Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention generally relates to an electrical bicycle
shift control device. More specifically, the present invention relates
to an electrical shift control assembly, which has at least one
electrical shift control device clamped onto the handlebar to provide
at least one additional location to control shifting.
[0003] 2. Background Information
[0004] Bicycling is becoming an increasingly more popular form
of recreation as well as a means of transportation. Moreover, bicycling
has become a very popular competitive sport for both amateurs and
professionals. Whether the bicycle is used for recreation, transportation
or competition, the bicycle industry is constantly improving the
various components of the bicycle. One component that has been extensively
redesigned is the bicycle shifting mechanism.
[0005] In the past, the operating force applied by the fingers
to a shift control lever was transmitted to the drive component
of a bicycle shifting mechanism by a cable that was fixed at one
end to the control lever. More recently, electric switches mounted
on the handlebar have been used instead of mechanical control levers
in order to operate the bicycle shifting mechanism. For example,
as shown in Japanese Laid-Open Patent Application No. 5-338581 and
U.S. Pat. No. 5,358,451, a plurality of electric switches may be
provided at a plurality of handlebar locations in order to allow
for quicker shifts and to enhance responsiveness. However, it is
often inconvenient to move the hands around the handlebar to operate
the brakes and the electric switches depending on the hand position
at a given time. Additionally, these typical braking devices and/or
electric switches can be difficult or at least cumbersome to assemble
and install on the bicycle. Furthermore, these typical braking devices
and/or electric switches can be unsightly.
[0006] In view of the above, it will be apparent to those skilled
in the art from this disclosure that there exists a need for an
improved electrical bicycle shift control assembly with an improved
electrical shift control device. This invention addresses this need
in the art as well as other needs, which will become apparent to

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0042] Selected embodiments of the present invention will now be
explained with reference to the drawings. It will be apparent to
those skilled in the art from this disclosure that the following
descriptions of the embodiments of the present invention are provided
for illustration only and not for the purpose of limiting the invention
as defined by the appended claims and their equivalents.
[0043] Referring initially to FIGS. 1 and 2, a bicycle 10 is illustrated
with a pair of electrical shift/brake control devices 12R and 12L
(only one shown in FIG. 1) and a pair of additional electrical shift
control devices 13R and 13L (only one shown in FIG. 1) mounted on
a bicycle handlebar 14 in accordance with the present invention.
The electrical shift/brake control devices 12R and 12L and the additional
electrical shift control devices 13R and 13L form parts of a brake
and shift control system or assembly of the bicycle 10 in accordance
with the present invention. The additional electrical shift control
devices 13R and 13L are preferably mounted to a central transverse
portion T of the handlebar 14 in accordance with the present invention,
as explained below. The transverse portion T is preferably straight
(i.e., linear).
[0044] The right and left hand side control devices 12R and 12L
are essentially identical in construction and operation, except
that that are mirror images. Moreover, the parts of right and left
hand side control devices 12R and 12L that are identical or mirror
images will be given the same reference numerals for the sake of
brevity. The additional shift control devices 13R and 13L are also
essentially identical in construction and operation, except that
that are mirror images. Thus, only one of the shift control devices
13R and 13L will be discussed and illustrated herein. Moreover,
the parts of right and left hand side shift control devices 13R
and 13L that are identical or mirror images will be given the same
reference numerals for the sake of brevity.
[0045] The right hand side control device 12R is operatively coupled
to a rear derailleur 16 via a bicycle computer unit 24, while the
left hand side control device 12L is operatively coupled to a front
derailleur 20 via the bicycle computer unit 24. The additional right
hand side shift control device 13R is also operatively coupled to
the rear derailleur 16 via the bicycle computer unit 24, while the
additional left hand side shift control device 13L is also operatively
coupled to the front derailleur 20 via the bicycle computer unit
24. Additionally, the right hand side control device 12R is preferably
directly mechanically coupled to a rear brake device 18 via a brake
cable 18a, while the left hand side control device 12L is preferably
directly mechanically coupled to a front brake device 22 via a brake
cable 22a. The cycle computer unit 24 also forms a part of the brake
and shift control system or assembly of the bicycle 10 mentioned
above. The cycle computer unit 24 operates the rear and front derailleurs
16 and 20 via electrical wires 16a and 20a in a conventional manner.
Preferably, at least one of the additional electrical shift control
devices 13R and 13L supports the cycle computer unit 24, as explained
below.
[0046] The brake and shift control system of the bicycle 10 controls
the rear derailleur 16, the rear brake device 18, the front derailleur
20 and the front brake device 22. In particular, the brake and shift
control system of the bicycle 10 mechanically controls the rear
brake device 18 and the front brake device 22, while the brake and
shift control system of the bicycle 10 electronically controls the
rear derailleur 16 and the front derailleur 20. Thus, the brake
and shift control system of the bicycle 10 preferably includes a
conventional mechanical brake control system as well as an electrical
shift control system or assembly in accordance with the present
invention, as explained below.
[0047] Since most of the parts of the bicycle 10 are well known
in the art, the parts of the bicycle 10 will not be discussed or
illustrated in detail herein, except for the parts relating to the
present invention. Moreover, various conventional bicycle parts,
which are not illustrated and/or discussed in detail herein, can
also be used in conjunction with the present invention. In other
words, it will be apparent to those skilled in the art from this
disclosure that various modifications can be made to the various
parts of the bicycle 10 without departing from the present invention,
as needed and/or desired.
[0048] Referring now to FIGS. 2-11, the additional electrical shift
control devices 13R and 13L will now be discussed in more detail.
Basically, each of the shift control devices 13R and 13L includes
a handlebar mounting portion 30 and an electrical shift control
switch portion 32. The handlebar mounting portion 30 is configured
to be clamped onto the transverse portion T of the handlebar 14.
The electrical shift control switch portion 32 is detachably coupled
to the handlebar mounting portion 30 via a protrusion and recess
arrangement and a threaded fastener or screw 34. The parts of the
protrusion and recess arrangement will be discussed in more detail
below.
[0049] For the sake of convenience, the "electrical shift
control switch portion 32" will also simply be referred to
as "the electrical switch portion 32" hereinafter. When
the fastener 34 is removed, the electrical (shift control) switch
portions 32 can be removed from the handlebar mounting portions
30 without removing the handlebar mounting portions 30 from the
handlebar 14. The electrical (shift control) switch portions 32
of the shift control devices 13R and 13L are utilized by the rider
to shift the rear derailleur 16 and the front derailleur 20, respectively.
[0050] Referring mainly to FIGS. 2-7, the handlebar mounting portion
30 basically includes a tubular clamping member 36, a switch mounting
structure 38 and a computer support leg 40. The switch mounting
structure 38 is fixedly coupled to the tubular clamping member 36,
while the computer support leg 40 is removably coupled to the tubular
clamping member 36. The electrical switch portion 32 is detachably
coupled to the switch mounting structure 38 of the handlebar mounting
portion 30, as explained below in more detail. Preferably, the switch
mounting structure 38 and the tubular clamping member 36 are integrally
formed together as a one-piece, unitary member of a lightweight,
rigid material such as cast aluminum or hard plastic.
[0051] The tubular clamping member 36 includes a first attachment
end 36a, a second attachment end 36b and a band section 36c extending
between the attachment ends 36a and 36b. A bolt 42a and a nut 42b
couple the attachment ends 36a and 36b together to mount the tubular
clamping member 36 on the handlebar 14. Specifically, the nut 42b
is non-rotatably coupled to the second attachment end 36b, while
the bolt 42a is rotatably coupled to the first attachment end 36a.
Thus, rotation of the bolt 42a causes the attachment ends 36a and
36b to move toward each other to reduce the effective inner diameter
of a curved mounting surface 36d of the band section 36c. The curved
surface 36d contacts the outer surface of the handlebar 14. Accordingly,
the tubular clamping member 36 is clamped onto the handlebar 14.
[0052] The computer support leg 40 is mounted on the bolt 42a between
the attachment ends 36a and 36b. Specifically, a pair of resilient
members 44 (e.g. rubber washers) are arranged on opposite sides
of the computer support leg 40 such that the support leg 40 is securely
held between opposing surfaces of the attachment ends 36a and 36b
on the bolt 42a. The resilient members 44 are deformable such that
the computer support leg 40 and the members 44 do not interfere
with securing the tubular clamping member 36 onto the handlebar
14. In other words, the resilient members will deform to become
effectively thinner if needed in order to securely clamp the tubular
clamping member 36 onto the handlebar 14.
[0053] The computer support leg 40 basically includes a bicycle
attachment end 40a, a computer attachment end 40b and a bent section
40c disposed between the bicycle attachment end 40a and the computer
attachment end 40b. The bicycle attachment end 40a has opposed flat
surfaces with a through hole extending therebetween for receiving
the bolt 42a. The computer attachment end 40b is releasably coupled
to the cycle computer by a snap-fit or using fasteners (not shown)
in a conventional manner. The bent section 40c is configured and
arranged such that the bicycle computer unit 24 is longitudinally
offset from the band section 36c of the tubular clamping portion
36.
[0054] In the illustrated embodiment, the computer support legs
40 of the additional shift control devices 13R and 13L are preferably
integrally formed together as a one-piece, unitary computer support
member 41 that has a substantially U-shaped configuration, as best
seen in FIGS. 2 and 3. Thus, the computer attachment end 40b of
one of the computer support legs 40 is preferably common to the
other computer support leg 40. However, it will be apparent to those
skilled in the art from this disclosure that the computer support
legs 40 could be formed as separate members, and/or that one of
the computer support legs 40 could be completely eliminated if needed
and/or desired. If one of the computer support legs 40 is eliminated,
it will be apparent to those skilled in the art from this disclosure
that the single computer support leg 40 could be integrally formed
with the tubular clamping member 36 of one of the shift control
devices 13R and 13L, as discussed below with reference to another
embodiment of the present invention. In any case, the computer support
leg or legs 40 are preferably configured and arranged such that
the bicycle computer unit 24 is longitudinally offset from the band
sections 36c along the handlebar 14, as best seen in FIGS. 2 and
3.
[0055] The switch mounting structure 38 basically includes a pair
of longitudinal rails 46 extending from an abutment member 48 to
form a substantially T-shaped longitudinal recess 50 with a single
open end. A hexagonal shaped cutout 52 preferably extends through
the abutment member 48, the longitudinal recess 50 and partially
through the rails 46, as best seen in FIGS. 9 and 11. The nut 42b
is received in the cutout 52 prior to attaching the electrical switch
portion 32 to the handlebar mounting portion 30. A stepped through
bore 48a is formed in the abutment member 48 to receive the fastener
34. The switch mounting structure 38 (i.e., the T-shaped recess
50) preferably forms part of the protrusion and recess arrangement,
which couples the handlebar mounting portion 30 with the electrical
switch portion 32 mentioned above.
[0056] The bicycle computer unit 24 basically includes a computer
housing 54 with a display screen 56. The display screen is preferably
an LCD display screen. The internal workings of the bicycle computer
unit 24 are well known in the art. Thus, the bicycle computer unit
24 will not be discussed and/or illustrated in detail herein, except
as related to the present invention. The computer housing 54 basically
encloses the internal parts of the bicycle computer unit 24 such
as the CPU, ROM, RAM, I/O interface, etc. The bicycle computer unit
24 can be powered by an internal power supply (e.g. a battery) or
externally as needed and/or desired. The computer unit 24 receives
electrical signals from the various electrical switches of the bicycle
10, processes the signals, and then operates/actuates (i.e., via
electrical signals sent through the cords 16a and 20a) the rear
and front derailleurs 16 and 20 in a conventional manner.
[0057] The computer housing 54 also is utilized to support the
bicycle computer unit 24 by the computer support legs 40. In particular,
the computer housing 54 includes a bottom surface 54a configured
to be coupled to the computer attachment end 40b of the computer
support legs 40 as best seen in FIG. 2. In particular, the bottom
surface 54a is preferably configured to be snap fit with the computer
attachment end 40b, or configured with threaded holes to be attached
via fasteners in a conventional manner. In the illustrated embodiment,
the computer attachment end 40b of the computer support leg 40 and
the bottom surface 54a are preferably configured to be snap-fitted
together in a conventional manner. Accordingly, the precise structure
of the computer attachment end 40b of the computer support leg 40
as well as the bottom surface 54a will not be discussed and/or illustrated
in detail herein, except as related to the present invention.
[0058] Referring to FIGS. 2-14, the electrical switch portion 32
will now be explained in more detail. The electrical switch portion
32 is electrically coupled to an electrical cord 58 having an electrical
conductor 58a, an electrical conductor 58b and an electrical conductor
58c. The electrical cord 58 is electrically coupled to the bicycle
computer unit 24. The electrical switch portion 32 basically includes
a housing 60, an operating member 61 and an electrical contact assembly
62, as seen in FIGS. 7 and 8. The operating member 61 is rotatably
coupled to the housing 60 and operatively coupled to the electrical
contact assembly 62 to be selectively moved relative to the handlebar
mounting portion 30 (i.e., to first and second actuating positions
from a neutral, rest position). The electrical contact assembly
62 is mounted within the housing 60 and is configured and arranged
to be operated by the operating member 61.
[0059] The electrical contact assembly 62 is electrically coupled
to the electrical contacts 58a-58c of the electrical cord 58. As
explained below in more detail, the electrical switch portion 32
(i.e., the operating member 61) has a first actuating or upshift
position, a second actuating or downshift position and a neutral
or rest position located between the first and second actuating
positions as best seen in FIGS. 12-14. Accordingly, the electrical
switch portion 32 (i.e., the operating member 61) can be utilized
for both upshifting and downshifting one of the derailleurs 16 and
20. The first and second actuating positions are arranged on opposite
sides of the neutral position.
[0060] Of course, it will be apparent to those skilled in the art
from this disclosure that the upshifting and downshifting positions
of the operating member 61 could be reversed if needed and/or desired,
depending on how the cord 58 is connected. In other words, the additional
electrical shift control devices 13R and 13L are preferably identical,
except for the way in which the operating members 61 are configured.
Specifically, the operating members 61 are mounted such that they
are mirror images of each other. However, the cords 58 can be connected
in the same manner or differently so the additional electrical shift
control devices 13R and 13L operate in the same manner or slightly
different manners. For example, one of the additional electrical
shift control devices 13R and 13L can be connected to its respective
cord 58 such that a particular actuating movement (e.g., clockwise
movement of the operating member 61) produces an upshift, while
the other of the additional electrical shift control devices 13R
and 13L can be connected to its respective cord 58 such that a particular
actuating movement (e.g., clockwise movement of the operating member
61) produces a downshift, and vice versa.
[0061] Preferably, the housing 60 is constructed of two pieces.
For example, the housing 60 as illustrated, includes a rectangular
cup-shaped base element 64 and a rectangular cover element 66 that
is coupled to the base element 64. The base element 64 and cover
element 66 are each preferably constructed of a hard rigid material
such as a hard rigid plastic or metal material. The electrical contact
assembly 62 is housed within the housing 60 between the base element
64 and the cover element 66 and electrically coupled to the electrical
conductors 58a-58c of the electrical cord 58, as mentioned above.
Specifically, the electrical contact assembly 62 is preferably mounted
in the base element 64 as seen in FIG. 8. After all electrical connections
between the electrical contact assembly 62 and the cord 58 are made,
the cover element 66 is fixedly coupled to the base element (e.g.,
by a snap fit, glue, fasteners, or any other suitable attachment
technique).
[0062] Preferably, the base element 64 includes a wire opening
64a that is configured and arranged to receive a rubber wire mounting
member 59 that has the cord 58 extending outwardly therethrough
as best seen in FIG. 7. The wire mounting member 59 seals the wire
opening 64a so that a filler material such an epoxy resin filler
material can be retained in the area B after all electrical connections
between the cord 58 and the electrical switch portion 32 are made.
[0063] The cover element 66 includes a substantially T-shaped longitudinal
projection 68 with a longitudinally extending threaded blind bore
68a extending from an end surface 68b that is configured to threadedly
receive the threaded fastener 34 therein. The projection 68 preferably
has a cross-sectional shape identical or substantially identical
to the cross-sectional shape of the recess 52 of the switch mounting
structure 38. In other words, the projection 68 is configured to
be slid into the recess 52 until the end surface 68b of the projection
68 contacts the abutment member 48. The fastener 34 is then inserted
through the hole 48a of the abutment member 48 into the threaded
hole 68a to couple the electrical switch portion 32 to the handlebar
mounting portion 30. In other words, after the fastener 34 couples
the electrical switch portion 32 to the handlebar mounting portion
30, the electrical switch portion 32 is non-movable relative to
the handlebar mounting portion 30. However, if the fastener 34 is
subsequently removed, the electrical switch portion 32 is slidable
relative to and removable from the handlebar mounting portion 30,
without removing the handlebar mounting portion 30 from the handlebar
14.
[0064] The T-shaped protrusion 68 and the T-shaped recess 52 form
parts of the protrusion and recess arrangement mentioned above.
Of course, it will be apparent to those skilled in the art from
this disclosure that other types of protrusion and recess arrangements
can be used in conjunction with the present invention. For example,
the protrusion and recess arrangement illustrated herein could be
reversed if needed and/or desired. Furthermore, it will be apparent
to those skilled in the art from this disclosure that the protrusion
and recess arrangement illustrated herein could be modified without
departing from the present invention. For example, the fastener
34 could be eliminated and the protrusion and recess arrangement
illustrated herein could be provided with a snap-fit retaining structure
(i.e., a bulge/detent arrangement) rather than using a separate
fastener.
[0065] The operating member 61 protrudes out from the housing 60
such that rotational movement of the operating member 61 causes
the electrical contact assembly 62 to move from a normal or rest
position to one of the two actuating positions as explained below.
The operating member 61 basically has a knob or dial-shaped actuator
70, a pivot shaft 72 and a toggle member 74. The actuator 70 is
fixedly attached the outer end of the pivot shaft 72 by a set pin
76 that contacts a flat portion of the outer end of the pivot shaft
72. The inner end of the pivot shaft 72 has the toggle member 74
fixedly coupled thereto. Thus, rotation of the actuator 70 by the
rider causes the pivot shaft 72 and the toggle member 74 to rotate
therewith.
[0066] Preferably, a bearing assembly 78 is positioned between
the housing 60 and the pivot shaft 72 such that the operating member
61 pivots or rotates smoothly about a rotational operating axis
or pivot axis X. Preferably, the pivot axis X of the operating member
61 is non-parallel to a center axis C of the transverse portion
T of the handlebar 14. The pivot axis X preferably intersects the
curved mounting surface 36d of the tubular clamping portion 36 as
best seen in FIG. 7.
[0067] A biasing element (coil spring) 79 is positioned between
the housing 60 and the toggle member 74 to normally bias the toggle
member 74, and thus, the operating member 61 to the normal rest
or neutral position from the first and second actuating positions.
In particular, one end of the spring 79 is preferably received in
an axial hole (not shown) of the base element 64, while the other
end of the spring 79 is preferably received in an axial hole (not
shown) of the toggle member 74. The axial holes (not shown) and
the spring 79 are preferably arranged and configured to bias the
operating member 61 to the neutral rest position from the first
and second actuating positions. The spring 79 preferably has a coiled
portion with at least two coils.
[0068] The toggle member 74 has an annular mounting portion 74a
with a radially extending projection 74b extending outwardly from
the mounting portion 74a. The mounting portion 74a preferably has
a non-circular opening with a portion of the pivot shaft 72 non-rotatably
received therein. The projection 74b engages the electrical contact
assembly 62 in response to rotation of the operating member 61,
as explained below.
[0069] The actuator 70 basically includes a dial element 70a, at
least one projection 70b and a pair flange elements 70c. The projection
70b extends radially outwardly from the outer edge of the dial element
70a to facilitate engagement with the rider's thumb or fingers.
The dial element 70a has a textured outermost edge 70d with a frustaconical
surface 70e extending therefrom as best seen in FIGS. 3-6. The flange
elements 70c project from the frustaconical surface 70e. The textured
outermost edge 70d as well as the flange elements 70c are configured
to facilitate engagement with the riders thumb or fingers. The flange
elements 70c are circumferentially spaced in opposite directions
from the projection 70b. The projection 70b preferably has a maximum
radial dimension measured relative to the textured outermost edge
70d that is about the same as a maximum radial dimension of the
dial element 70a measured between the pivot axis X and the outermost
edge 70d.
[0070] As seen in FIGS. 12-14, the electrical contact assembly
62 preferably includes a common contact bar 80, a first stationary
contact 82, a first movable (downshift) contact 84, a second stationary
contact 86, a second movable (upshift) contact 88 and a biasing
element 90 formed of a pair of leaf springs 90a and 90b. Generally,
when the electrical switch portion 32 (i.e., the operating member
61) is in the rest/neutral position, the projection 74b of the toggle
member 74 (i.e. of the operating member 61) is located centrally
between the first and second movable contacts 84 and 88. In particular,
the biasing element 90 holds the toggle member 74 of the operating
member 61 in the rest position between the first and second movable
contacts 84 and 88. The spring 79 also holds the toggle member 74
in the rest position.
[0071] However, when the rider rotates the actuator 70 of the operating
member 61, this causes the pivot shaft 72 to pivot the toggle member
74 such that the projection 74b is pressed against one of the movable
contacts 84 and 88. This pivotal movement of the toggle member 74
causes one of the movable contacts 84 and 88 to be deflected such
that the deflected movable contact directly contacts the corresponding
one of the stationary contacts 82 and 86. More specifically, when
the actuator 70 of the operating member 61 is rotated in a clockwise
direction as seen by the rider (FIG. 13), the toggle member 74 deflects
the first movable contact 84 such that the first movable contact
84 contacts the first stationary contact 82. The rider's view of
the actuator is reversed from that illustrated in FIGS. 12-14. Thus,
an electrical connection is made between the first stationary contact
82 and the first movable contact 84 such that a shift control signal
is sent to the cycle computer unit 24, which in turn operates one
of the derailleurs 16 and 20 to cause a shift to occur. If the actuator
70 of the operating member 61 is rotated in a counterclockwise direction
as seen by the rider (FIG. 14), an opposite shift of one of the
derailleurs 16 and 20 occurs. In particular, rotation of the actuator
70 of the operating member 61 causes the toggle member 74 to deflect
the second movable contact 88 against the second stationary contact
86 to result in an electrical connection therebetween. The rider's
view of the actuator is reversed from that illustrated in FIGS.
12-14. This electrical connection causes a control signal to be
inputted into the cycle computer unit 24 such that a shift control
signal is sent to one of the derailleurs 16 and 20.
[0072] The cycle computer unit 24 is electrically coupled to the
electrical switch portion 32 via the electrical cord 58, as mentioned
above. In particular, the first electrical conductor 58a of the
electrical cord 58 is electrically connected to the common contact
bar 80. The second electrical conductor 58b of the electrical cord
58 is electrically connected to the first stationary contact 82,
while the third electrical conductor 58c of the electrical cord
58 is electrically connected the second stationary contact 86. When
the first contacts 82 and 84 are touching, the first conductor 58a
is electrically connected to the second electrical conductor 58b
to transmit a downshift control signal to the cycle computer unit
24. On the other hand, when the second contacts 86 and 88 are touching,
the first conductor 58a is electrically connected to the third electrical
conductor 58c to transmit an upshift control signal to the cycle
computer unit 24.
[0073] Basically, the first stationary contact 82 includes a wiring
plate 82a and a contact element 82b with a first stationary engagement
surface. The first stationary contact 82 is constructed of a rigid
electrical conductive material such as those known in the art. The
first stationary contact 82 is fixedly secured to the housing 60
when the base element 64 and the cover element 66 are fixedly coupled
together. The second electrical conductor 58b of the electrical
cord 58 is electrically connected to the first stationary contact
82 by soldering or otherwise attaching the conductor to the wiring
plate 82a.
[0074] The first movable contact 84 includes a first mounting element
84a with a contact element 84b mounted on one end of the first mounting
element 84a, and a second mounting element 84c coupled to the other
end of the first mounting element 84a. The elements 84a-84c of the
first movable contact 84 are constructed of rigid electrical conductive
materials such that an electrical path is created by these elements.
The first mounting element 84a is swingably mounted to the common
contact bar 80 and the second mounting element 84c such that the
first mounting element 84a moves between a normal or rest position
and an actuating position in response to rotation of the actuator
70 of the operating member 61. Thus, the contact element 84b has
a movable engagement surface that is arranged and configured to
move with the first mounting element 84a when the operating member
61 is operated. In other words, the movable engagement surface of
the contact element 84b of the first movable contact 84 selectively
moves into electrical engagement with the first stationary engagement
surface of the contact element 82b of the first stationary contact
82 upon clockwise rotation of the actuator 70 of the operating member
61 to the first actuating position as seen by the rider (FIG. 13).
[0075] The second mounting element 84c is coupled between the common
contact bar 80 and the free end of the first mounting element 84a
to control the swinging or pivotal movement of the first mounting
element 84a. Thus, the second mounting element 84c is pivotally
mounted at its first end to the common contact bar 80 and at its
second end to the first mounting element 84a. One end of the leaf
spring 90a of the biasing element 90 is coupled to the common contact
bar 80, while the other end of the leaf spring 90a is coupled to
the first mounting element 84a such that the first and second mounting
elements 84a and 84c urge the toggle member 74 of the operating
member 61 to the center rest position and the contact element 84b
out of engagement with the stationary contact element 82b.
[0076] This arrangement of the leaf spring 90a together with the
first and second mounting elements 84a and 84c form an audible clicking
element that is configured and arranged to produce an audible sound
that occurs upon selective movement of the operating member 61 to
the first actuating position. In other words, an audible clicking
sound occurs simultaneous with the movable engagement surface of
the contact element 84b engaging the stationary engagement surface
of the contact element 82b.
[0077] Basically, the second stationary contact 86 includes a wiring
plate 86a and a contact element 86b with a second stationary engagement
surface. The second stationary contact 86 is constructed of a rigid
electrical conductive material such as those known in the art. The
second stationary contact 86 is fixedly secured to the housing 60
when the base element 64 and the cover element 66 are fixedly coupled
together. The third electrical conductor 58c of the electrical cord
58 is electrically connected to the second stationary contact 86
by soldering or otherwise attaching the conductor to the wiring
plate 86a.
[0078] The second movable contact 88 includes a first mounting
element 88a with a contact element 88b mounted on one end of the
first mounting element 88a, and a second mounting element 88c coupled
to the other end of the first mounting element 88a. The elements
88a-88c of the second movable contact 88 are constructed of rigid
electrical conductive materials such that an electrical path is
created by these elements. The first mounting element 88a is swingably
mounted to the common contact bar 80 and the second mounting element
88c such that the first mounting element 88a moves between a normal
or rest position and an actuating position in response to rotation
of the actuator 70 of the operating member 61. Thus, the contact
element 88b has a movable engagement surface that is arranged and
configured to move with the first mounting element 88a when the
operating member 61 is operated. In other words, the movable engagement
surface of the contact element 88b of the second movable contact
88 selectively moves into electrical engagement with the second
stationary engagement surface of the contact element 86b of the
second stationary contact 86 upon counterclockwise rotation of the
actuator 70 of the operating member 61 to the second actuating position
as seen by the rider (FIG. 14).
[0079] The second mounting element 88c is coupled between the common
contact bar 80 and the free end of the first mounting element 88a
to control the swinging or pivotal movement of the first mounting
element 88a. Thus, the second mounting element 88c is pivotally
mounted at its first end to the common contact bar 80 and at its
second end to the first mounting element 88a. One end of the leaf
spring 90b of the biasing element 90 is coupled to the common contact
bar 80, while the other end of the leaf spring 90b is coupled to
the first mounting element 88a such that the first and second mounting
elements 88a and 88c urge the toggle member 74 of the operating
member 61 to the center rest position and the contact element 88b
out of engagement with the stationary contact element 86b.
[0080] This arrangement of the leaf spring 90b together with the
first and second mounting elements 88a and 88c form an audible clicking
element that is configured and arranged to produce an audible sound
that occurs upon selective movement of the operating member 61 to
the second actuating position. In other words, an audible clicking
sound occurs simultaneous with the movable engagement surface of
the contact element 88b engaging the stationary engagement surface
of the contact element 86b.
[0081] Referring now to FIGS. 1, 2, 15 and 16, the electrical shift/brake
control devices 12R and 12L will now be explained in more detail.
Basically, each of the electrical shift and brake control devices
12R and 12L includes a support member or brake lever bracket 130,
a brake lever 132, and a pair of electrical shift control switches
136. In the control device 12R, the brake cable 18a is fixedly coupled
to the brake lever 132 such that the inner wire is pulled when the
rider squeezes the brake lever 132. Likewise, the brake cable 22a
is fixedly coupled to the brake lever 132 of the control device
12L such that the inner wire is pulled when the rider squeezes the
brake lever 132.
[0082] As best seen in FIG. 2, the cycle computer unit 24 is electrically
coupled to the first and second electrical shift control switches
136 and 138 of each of the control devices 12R and 12L via a pair
of electrical cords 154.
[0083] In particular, each of the electrical cords 154 has a pair
of first electrical conductors 154a, a pair of second electrical
conductors 154b and a pair of third electrical conductors 154c,
which are electrical coupled to the electrical shift control switches
136 and 138. Each cord 154 connects one of the electrical shift
control switches 136 and the electrical shift control switches 138
to the bicycle computer 24. When one of the first conductors 154a
is electrically connected to one of the second electrical conductors
154b via the electrical shift control switch 136 or 138, then a
downshift signal is transmitted to the cycle computer unit 24. On
the other hand, when one of the first conductors 154a is electrically
connected to one of the third electrical conductors 154c via the
electrical shift control switch 136 or 138, then an upshift signal
is transmitted to the cycle computer unit 24. The cycle computer
unit 24, the electrical switch portions 32, the first electrical
shift control switches 136 and 138 form parts of the electrical
shift control system of the present invention.
[0084] Basically, each of the electrical shift control switches
136 and 138 includes a housing 160, an operating member 161 and
an electrical contact assembly 162, as seen in FIG. 22. The operating
member 161 is rotatably coupled to the housing 160 and operatively
coupled to the electrical contact assembly 162. The electrical contact
assembly 162 mounted within the housing 160 and configured and arranged
to be operated by the operating member 161. The construction of
the electrical contact assembly 162 is the same as the electrical
contact assembly 62, discussed above. Thus, the electrical shift
control switches 136 and 138 will not be discussed or illustrated
in detail herein. Rather the construction and operation of the electrical
shift control switches 136 and 138 can be readily determined from
the description of the electrical contact assembly 62, discussed
above.
Second Embodiment
[0085] Referring now to FIGS. 17 and 18, an additional bicycle
shift control device 213R is illustrated in accordance with a second
embodiment of the present invention is illustrated. This second
embodiment is identical to the first embodiment of the present invention
except that the computer support member 41 of the first embodiment
has been replaced with a modified computer support member 241 in
this second embodiment. Otherwise, this second embodiment is identical
to the first embodiment. Accordingly, this second embodiment will
not be discussed and/or illustrated in detail herein. Rather, it
will be apparent to those skilled in the art from this disclosure
that the descriptions and illustrations of the first embodiment
also apply to this second embodiment, except as explained and illustrated
herein. Identical parts of the first and second embodiments will
be referenced with identical reference numerals.
[0086] The modified computer support member 241 is identical to
the computer support member 41 of the first embodiment, except that
one of the computer support legs 40 of the first embodiment has
been eliminated and the computer support member 241 is integrally
formed with a handlebar mounting portion 230 of the right shift
control device 213R. Accordingly, the resilient elements 44 of the
first embodiment can be eliminated in this second embodiment. Moreover,
the left shift control device 13L of the first embodiment is used
in this second embodiment, except it does not support the bicycle
computer 24. The handlebar mounting portion 230 of the right shift
control device 213R is identical to the handlebar mounting portion
30 of the first embodiment, except that the handlebar mounting portion
230 has the computer support member 241 integrally formed therewith.
Thus, the handlebar mounting portion 230 will not be discussed in
further detail herein.
[0087] The computer support member 241 basically includes a computer
support leg 240 with a bicycle attachment end 240a, a computer attachment
end 240b and a bent section 240c disposed between the bicycle attachment
end 240a and the computer attachment end 240b. The computer attachment
end 240b supports the computer 24 in a manner identical to the first
embodiment. The bicycle attachment end 240a is integrally formed
with a tubular clamping portion 236 of the handlebar mounting portion
230. Thus, the computer support leg 240 of this second embodiment
is identical to the right computer support leg 40 of the first embodiment,
except the left computer support leg 4-0 of the first embodiment
has been eliminated and the bicycle attachment end 240a is integrally
formed with a tubular clamping portion 236 of the handlebar mounting
portion 230. Accordingly, this second embodiment will not be discussed
in further detail herein.
[0088] Of course, it will be apparent to those skilled in the art
from this disclosure that the computer support member could be integrally
formed with part of the additional left shift control device instead
of the additional right shift control device if needed and/or desired.
Moreover, it will be apparent to those skilled in the art from this
disclosure that the computer support member could be integrally
formed with parts of both the left and right shift control devices
if needed and/or desired. In such an arrangement, the computer support
member should have a configuration similar to the first embodiment,
but should be fixed to or integrally formed with both the handlebar
support portions of the shift control devices.
Third Embodiment
[0089] Referring now to FIGS. 19-21, an additional bicycle shift
control device 313R is illustrated in accordance with a third embodiment
of the present invention. The shift control device 313R illustrated
herein is preferably a right side device. However, it will be apparent
to those skilled in the art from this disclosure that the shift
control device 313R is preferably utilized in conjunction with a
modified left additional shift control device (not shown) that is
a mirror image of the shift control device 313R. Moreover, it will
be apparent to those skilled in the art from this disclosure that
the cycle computer 24 of the first and second embodiments is preferably
supported by the shift control device 313R and the modified left
additional shift control device (not shown) in accordance with the
first embodiment or the second embodiment. In other words, this
third embodiment is identical to the first embodiment of the present
invention except that the operating member 61 with the actuator
70 of the first embodiment has been replaced with a modified operating
member 361 with a modified lever-shaped actuator (element) 370 that
rotates about a rotation axis 3X in this third embodiment.
[0090] The inclination of the rotation axis 3X is oriented differently
in this third embodiment relative to the center axis C of the handlebar
14 than the rotation axis X of the first embodiment. However, this
third embodiment operates in a manner substantially identical to
the first embodiment. Accordingly, this third embodiment will not
be discussed and/or illustrated in detail herein. Rather, it will
be apparent to those skilled in the art from this disclosure that
the descriptions and illustrations of the first embodiment also
apply to this third embodiment, except as explained and illustrated
herein. Identical parts of the first and third embodiments will
be referenced with identical reference numerals. Parts that are
functionally identical will be referenced with identical reference
numerals but with "300" added to them. Parts of this third
embodiment that are functionally identical to parts of the first
embodiment can be better understood from the descriptions and illustrations
of the first embodiment, if needed.
[0091] The operating member 361 protrudes out from a modified housing
360 such that rotational movement of the operating member 361 causes
the electrical contact assembly 62 to move from a normal or rest
position to one of the two actuating positions, in a manner similar
to the first embodiment. The operating member 361 basically has
the lever-shaped actuator 370, the pivot shaft 72 of the first embodiment
and a modified toggle member 374. The actuator 370 is fixedly attached
the outer end of the pivot shaft 72 by a set pin (not shown) that
contacts a flat portion of the outer end of the pivot shaft 72 in
a manner identical to the first embodiment. The actuator 370 basically
includes a lever-shaped element 370a configured and arranged to
facilitate engagement with the rider's thumb and/or fingers (preferably
the rider's thumb).
[0092] The inner end of the pivot shaft 72 has the toggle member
374 fixedly coupled thereto. Thus, rotation of the actuator 370
by the rider causes the pivot shaft 72 and the toggle member 374
to rotate therewith. The toggle member 374 is identical to the toggle
member 74 of the first embodiment, except the toggle member 374
has a shorter radially extending projection 374b due to the location
and orientation of the operating axis 3X. The projection 374b engages
the electrical contact assembly 62 in response to rotation of the
operating member 361 in a manner identical to the first embodiment.
Thus, the toggle member 374 will not be discussed in further detail
herein.
[0093] Preferably, the bearing assembly 78 that is used in the
first embodiment is positioned between the housing 360 and the pivot
shaft 72 such that the operating member 361 pivots or rotates smoothly
about the rotational/operating axis or pivot axis 3X. Preferably,
the pivot axis 3X of the operating member 361 is non-parallel to
the center axis C of the transverse portion T of the handlebar 14.
The pivot axis 3X preferably intersects the curved mounting surface
36d of the tubular clamping portion 36.
[0094] The biasing element (coil spring) 79 that is used in the
first embodiment is also used in this embodiment. Specifically,
the biasing element 79 is positioned between the housing 360 and
the toggle member 374 to normally bias the toggle member 374 to
the normal rest or neutral position from the first and second actuating
positions. Thus, the operating member 361 is normally maintained
in the normal rest or neutral position, similar to the first embodiment,
as discussed above. In particular, one end of the spring 79 is preferably
received in an axial hole (not shown) of a modified base element
364 of the housing 360, while the other end of the spring 79 is
preferably received in an axial hole (not shown) of the toggle member
374. The axial holes (not shown) and the spring 79 are preferably
arranged and configured to bias the operating member 361 to the
neutral rest position from first and second actuating positions
in a manner identical to the first embodiment. The spring 79 preferably
has a coiled portion with at least two coils.
Fourth Embodiment
[0095] Referring now to FIGS. 22-24, an additional bicycle shift
control device 413R is illustrated in accordance with a fourth embodiment
of the present invention. The shift control device 413R illustrated
herein is preferably a right side device. However, it will be apparent
to those skilled in the art from this disclosure that the shift
control device 413R is preferably utilized in conjunction with a
modified left additional shift control device (not shown) that is
a mirror image of the shift control device 413R. Moreover, it will
be apparent to those skilled in the art from this disclosure that
the cycle computer 24 of the first and second embodiments is preferably
supported by the shift control device 413R and the modified left
additional shift control device (not shown) in accordance with the
first embodiment or the second embodiment. In other words, this
fourth embodiment is identical to the first embodiment of the present
invention except that the operating member 61 with the actuator
70 of the first embodiment has been replaced with a modified operating
member 461 with a modified lever-shaped actuator (element) 470 that
rotates about a rotation axis 4X in this fourth embodiment.
[0096] The inclination of the rotation axis 4X is oriented differently
in this fourth embodiment relative to the center axis C of the handlebar
14 than the rotation axis X of the first embodiment. However, this
fourth embodiment operates in a manner substantially identical to
the first embodiment. Accordingly, this fourth embodiment will not
be discussed and/or illustrated in detail herein. Rather, it will
be apparent to those skilled in the art from this disclosure that
the descriptions and illustrations of the first embodiment also
apply to this fourth embodiment, except as explained and illustrated
herein. Identical parts of the first and fourth embodiments will
be referenced with identical reference numerals. Parts that are
functionally identical will be referenced with identical reference
numerals but with "400" added to them. Parts of this fourth
embodiment that are functionally identical to parts of the first
embodiment can be better understood from the descriptions and illustrations
of the first embodiment, if needed.
[0097] The operating member 461 protrudes out from a modified housing
460 such that rotational movement of the operating member 461 causes
the electrical contact assembly 62 to move from a normal or rest
position to one of the two actuating positions, in a manner similar
to the first embodiment. The operating member 461 basically has
the lever-shaped actuator 470, the pivot shaft 72 of the first embodiment
and a modified toggle member 474. The actuator 470 is fixedly attached
the outer end of the pivot shaft 72 by a set pin (not shown) that
contacts a flat portion of the outer end of the pivot shaft 72 in
a manner identical to the first embodiment. The actuator 470 basically
includes a pair of finger operated lever-shaped elements 470a configured
and arranged to facilitate engagement with the rider's thumb or
fingers. The actuator 470 preferably has a V-shape as seen in FIG.
23 such that one of the elements 470a can be actuated by the rider's
thumb, while the other element 470a can be actuated by the rider's
finger(s).
[0098] The inner end of the pivot shaft 72 has the toggle member
474 fixedly coupled thereto. Thus, rotation of the actuator 470
by the rider causes the pivot shaft 72 and the toggle member 474
to rotate therewith. The toggle member 474 is identical to the toggle
member 74 of the first embodiment, except the toggle member 474
has an axially extending part 474c extending from a radially extending
projection 474b due to the location and orientation of the operating
axis 4X. The axially extending part 474c selectively engages the
electrical contact assembly 62 in response to rotation of the operating
member 461 in a manner substantially identical to the first embodiment.
Thus, the toggle member 474 will not be discussed in further detail
herein.
[0099] Preferably, the bearing assembly 78 that is used in the
first embodiment is positioned between the housing 460 and the pivot
shaft 72 such that the operating member 461 pivots or rotates smoothly
about the rotational/operating axis or pivot axis 4X. Preferably,
the pivot axis 4X of the operating member 461 is non-parallel to
the center axis C of the transverse portion T of the handlebar 14.
The pivot axis 4X preferably intersects the curved mounting surface
36d of the tubular clamping portion 36. Moreover, the pivot axis
4X preferably substantially passes through the center axis C of
the handlebar 14 to form a substantially right angle relative thereto.
[0100] The biasing element (coil spring) 79 that is used in the
first embodiment is also used in this embodiment. Specifically,
the biasing element 79 is positioned between the housing 460 and
the toggle member 474 to normally bias the toggle member 474 to
the normal rest or neutral position from the first and second actuating
positions. Thus, the operating member 461 is normally maintained
in the normal rest or neutral position, similar to the first embodiment,
as discussed above. In particular, one end of the spring 79 is preferably
received in an axial hole (not shown) of a modified base element
464 of the housing 460, while the other end of the spring 79 is
preferably received in an axial hole (not shown) of the toggle member
474. The axial holes (not shown) and the spring 79 are preferably
arranged and configured to bias the operating member 461 to the
neutral rest position from first and second actuating positions
in a manner identical to the first embodiment. The spring 79 preferably
has a coiled portion with at least two coils.
