Abstract
A rotatable base apparatus for use with a hose reel enclosure. The
base comprises an upper and a lower portion. A bearing is located
in between the upper and lower portions and allows the portions to
rotate with respect to each other. The bearing can comprise balls
mounted in sockets in the lower base portion which ride in a track
in the upper base portion. Clips are provided on the upper base portion
to secure the hose reel enclosure thereto. This arrangement allows
the user to remove the hose from the reel in any direction without
the danger of the hose reel enclosure tipping over. The hose reel
enclosure will rotate to the direction in which the hose is being
removed. It also allows the hose reel enclosure to rotate to the direction
that the hose is being wound onto the reel. This prevents the hose
from being unevenly wound onto the reel, i.e. piling up on one side
of the reel.

Description
FIELD OF THE INVENTION
[0001] This invention pertains to reels for use in storage of flexible
hoses and more particularly, to a hose reel having a pivotable base
to allow the hose reel to turn in the direction the hose is being
removed from or rewound onto the reel.
BACKGROUND INFORMATION
[0002] Portable hose reel dispensers for handling and storage of
flexible water hoses, such as garden and air hoses, have gained
wide public acceptance. While the construction of hose reels is
quite varied, such reels are primarily constructed of molded plastic
components having a centrally disposed rotatable spool for reeling
of the flexible hose, and a frame for supporting of the spool. Recently
there has been recognized a need for aesthetically pleasing hose
reel storage devices. The hose and reel being mounted in an aesthetically
pleasing enclosure. For more information concerning the structure
and operation of these hose reel storage devices, reference may
be made to U.S. Pat. Nos. 6,050,291 and 5,404,900 the teachings
of which is hereby incorporated by reference. When the hose reel
is located in the type of enclosure disclosed in U.S. Pat. No. 6,050,291
a problem arises with removal of the hose from the reel and winding
the hose back onto the reel. If the hose is not substantially perpendicular
to the reel when it is removed there is a tendency for the reel
and enclosure to tip over on its side in the direction that the
hose is being removed. Also, when the hose is wound back on the
reel, if it is not substantially perpendicular to the reel there
is a tendency for the hose to pile up on one end of the reel and
not evenly distribute itself along the length of the reel.
[0003] U.S. Pat. No. 5,404,900 recognizes the problem of the hose
not being substantially perpendicular to the reel when it is removed
and wound back thereon. Swivel bolt 28, FIGS. 4 and 12, permit the
reel to be turned toward the direction that the hose is lying, on
the ground, to allow the hose to be evenly wound onto the reel.
[0004] U.S. Pat. No. 5,462,298 is directed to a hose reel cart
which utilized a circular bearing surface to support an upper surface
34 on a lower surface 34. The hose and reel are mounted on the upper
surface. This arrangement allows the hose and reel to pivot in the
direction of use. However, an enclosure which will hold the reel
and hide it from view is not provided by this device.
[0005] U.S. Pat. No. 6,478,265 is directed to a conventional wall-mounted
bracket 10 which has a reel 12 for a hose. The bracket 10 is mounted
onto a sleeve 32 which in turn is pivotally mounted on post 26.
This arrangement allows the hose and reel to be pivoted to the direction
of use. An enclosure for the hose reel is not provided and hence
the reel is not aesthetically pleasing
[0006] U.S. Pat. No. 5,080,322 discloses a turntable wherein the
turntable element 10 and bearings 22 are made of plastics. Turntable
element 10 is positioned between upper rotatable support board 12
and lower base board 14. A central shaft 8 passes through element
10 and rotatably connects the two boards so they can move freely
relative to one another. In this patent, a television is placed
on the upper support board and can rotate freely while the lower
base board remains stationary. There is no indication that this
could be used to support an hose and reel.
[0007] U.S. Pat. No. 4,757,838 discloses a swivel fire hose reel.
A hose reel 14 is rotatably mounted to base 12 via swivel joint
28. When in storage the hose is fully supported by the reel 14.
When the hose is pulled off the reel, the reel 14 and guard 16 will
rotate so the hose may be deployed from the reel in the direction
of the fire.
[0008] U.S. Pat. No. 6,807,982 discloses a garden hose storage
device which is also used to transport the hose. The garden hose
is held in compartment 26 located between outer cylindrical wall
14 and inner cylindrical wall 18. Inner wall 18 is attached to mounting
post 30. Post 30 has a lower section 32 with a water inlet connector
34 and an axially aligned upper section 36 rotatably mounted on
the lower section 32. Sections 32 and 36 are coupled together with
a rotatable watertight coupling 38. The hose is removed from the
storage device through hose guide 42. This does not allow for the
deployment of the hose in any direction without applying an undue
side force to the storage device.
[0009] These patents fail to teach or disclose a rotary table or
base on which an enclosed hose reel can be mounted in accordance
with the instant invention. What is lacking in the art is an enclosed
hose reel which is pivotable so that the hose may be dispensed in
various horizontal directions without tipping over the enclosure.
Also, when the hose is wound back on the reel the pivotable base
prevents the hose from rolling up on one side of the reel leaving
the other side empty.
BRIEF DESCRIPTION OF THE INVENTION
[0010] Among the several aspects and features of the present invention
may be noted the provision of a rotary base on which an enclosed
hose reel is mounted. This permits the hose to be withdrawn from
and wound back onto the reel from any angle. Since the object or
objects which need water may not always be in front of the hose
reel, the hose may have to be removed from the reel at a substantial
angle relative to the front of the reel which will impose an undue
side force on the reel and enclosure. This usually results in the
entire hose enclosure tipping over onto its side. A similar problem
exists when the hose is wound back onto the reel at a substantial
angle from the front of the enclosure. The hose tends to pile up
on one side of the reel so that the diameter of the hose on the
reel will become larger that the allowable space within the hose
enclosure. This results in the hose not being completely wound back
onto the reel.
[0011] In one embodiment, resilient clips spaced around the rotary
base are used to attach the hose reel enclosure to the rotary base.
This prevents separation of the enclosure and base. In another embodiment
sliding latches are utilized to attach the hose reel enclosure to
the base. This provides for easy separation of the base and hose
enclosure. In a further embodiment the base is integral with the
hose reel enclosure.
[0012] Thus, it is an object of the instant invention is to provide
a rotary base for an enclosed hose reel which will permit the hose
to be removed from and replaced onto the reel without exerting any
undue side force on the reel so as to result in the enclosure tipping
over.
[0013] Another object of the invention is to provide a rotary base
for an enclosed hose reel which includes resilient clips on the
base for attaching the hose enclosure to the base. This permits
easy and secure mounting of the hose reel enclosure.
[0014] A further object of the invention is to provide slidable
latches on the rotary base for attaching the hose enclosure to the
base. This permits relative easy removal of the hose enclosure from
the base.
[0015] Other objects and advantages of this invention will become
apparent from the following description taken in conjunction with
the accompanying drawings wherein are set forth, by way of illustration
and example, certain embodiments of this invention. The drawings
constitute a part of the specification and include exemplary embodiments
of the present invention and illustrate various objectives and features
thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0039] While the present invention is susceptible of embodiment
in various forms, there is shown in the drawings and will hereinafter
be described a presently preferred, albeit not limiting, embodiment
with the understanding that the present disclosure is to be considered
an exemplification of the invention and is not intended to limit
the invention to the specific embodiments illustrated.
[0040] Referring now to the figures, and generally to FIGS. 4-11,
and 13-16 there are shown rotary base members 200, 300, 400 and
500 embodying the principles of the present invention. The rotary
base members provide support for the hose reel enclosure 100 attached
thereto. The preferred hose reel enclosure is disclosed in U.S.
Pat. No. 6,742,740, the contents of which are incorporated herein
by reference.
[0041] In a preferred, albeit non-limiting embodiment, a hose reel
enclosure 100 is attached to the upper base element 202 of rotary
base member using clips 206 which can be integrally formed with
the upper element or added as a separate element. These clips cooperate
with the lowermost horizontal flanges on the bottom portion of the
sidewalls of the hose reel enclosure, as illustrated in FIG. 6 of
U.S. Pat. No. 6,742,740. Once the hose reel enclosure is securely
attached to the upper element 202, the upper element 202 may be
rotated relative to the lower base element 204. This is shown in
FIG. 3 of the drawings. The enclosed hose reel may now be easily
rotated in any direction so that the hose can be withdrawn from
and wound onto the reel in a substantially perpendicular direction
to the front face of the hose reel enclosure. This prevents the
above noted problems of the enclosure tipping over or the hose piling
up on one side of the reel.
[0042] The upper base element of the rotary base is supported on
the lower base element utilizing a bearing. In the embodiment illustrated
in FIGS. 10 and 11 the bearing comprises rotary balls 208 and circular
track 212. The rotary balls 208 are located in sockets 210 in the
top side of lower base element 204, They ride along on and support
circular track 212, which is located in the underside of the upper
base element 202. Circular track 212 comprises a pair of vertically
extending, circular flanges 214. The bottom portions of the flanges
214 engage the top portions of the balls 208. Additionally, means
are provided to rotatably attach the upper element to the lower
base element. These are resilient clips 216 and circular flange
218 illustrated in FIG. 11. The clips 216 are formed integrally
with the upper base element 202 and extend downwardly from the underside
thereof. Circular flange 218 is formed integrally with the lower
base element 204. Clips 216 are located on upper base element 202
in a circular pattern so as to fit within the inner circumference
of flange 218. A lip 220 on the lower portion of clip 216 engages
the lower circular edge portion of flange 218. This prevents separation
of the upper and lower base elements once they are snapped together,
while permitting rotation of the elements relative to each other.
These base elements may be separated from each other by flexing
clips 216 inwardly until lip 220 is no longer in engagement with
the lower portion of flange 218. Strengthening ribs 205 are integrally
formed in the lower portions of the upper and lower base elements
202 and 204, as shown in FIG. 7. This allows a smooth, aesthetically
pleasing appearance on the upper portions of the upper and lower
base elements.
[0043] Stakes 222 anchor the lower base element to the ground.
The stakes 222 pass through apertures 224 in the lower base element
204 as seen in FIG. 8A. The top of the stake 222 cooperates with
the aperture 224 in the lower base element to anchor the lower base
element to the ground. When a rotary force is exerted on the hose
enclosure 100 it can freely rotate with respect to the ground since
it is mounted on a rotary base 200. The lower element is also provided
with apertures 226 which are formed as an aperture with a plurality
of different diameter holes which can be punched out to accommodate
different size fasteners, such as screws, bolts, nails, etc. These
apertures are preferably integrally formed with the lower element
but could be added after the manufacture of the lower base element.
This provides a means to attach the lower element to structures,
such as decks, and vehicles, such as cars, trucks, boats and planes.
[0044] Another embodiment is illustrated in FIGS. 13 and 14. A
circular bearing surface 306 is integrally formed on the top side
of the lower base element 304. A circular track 308 is integrally
formed on the underside of upper base element 302. Elements 306
and 308 are formed utilizing low friction materials to allow for
relatively easy and smooth movement of one bearing surface with
respect to the other bearing surface. Additionally lubricants may
be utilized in between these bearing surfaces to provide for easy
rotation of the upper and lower base elements. The upper and lower
base elements are also connected together utilizing clips and a
circular flange similar to elements 216 and 218 in FIG. 11. Strengthening
ribs 310 are integrally formed in the top side of the lower element
304. Although not shown, the lower base element 304 is formed similar
to lower base element 204 and can be provided with apertures 224
and 226. These apertures provide a means to anchor the lower base
element to a surface.
[0045] A further embodiment is illustrated in FIG. 15. A race 406
is positioned between upper base element 402 and lower base element
404. The race comprises a circular base portion 408 onto which cylindrical
ball retention members 410 are formed. Balls are located within
ball retention members 410. A portion of the ball protrudes below
the lowermost portion of the ball retention member 410 and circular
base portion 408. This protruding portion of the ball rides in track
412 which is formed in the top side of the lower base element 404.
The circular base portion 408 also rides in track 412. Another portion
of the ball protrudes above the ball retention member 410. The diameter
of the hole at the top of the ball retention member 410 is selected
such that only a small portion of the ball protrudes above the ball
retention member. This protruding portion of the ball rides in a
track which is formed in the underside of the upper base element
402. The race 406 enables the even distribution of the balls along
track 412. Upper and lower base elements are also connected together
utilizing clips and a circular flange similar to elements 216 and
218 shown in FIG. 11.
[0046] In another embodiment, illustrated in FIGS. 12, 12A, and
12B latches 230 are used in place of the clips 206 of FIG. 4. The
latches 230 engage the same lowermost horizontal flanges on the
bottom portion of the sidewalls of the hose reel enclosure that
clips 206 engage. The latches are slidable from a retracted position,
shown in FIG. 12A, to an extended position, shown in FIG. 12B. In
the extended position, the latch 230 engage the lowermost horizontal
flanges of the hose reel enclosure securing the hose reel enclosure
to the upper element of the rotary base. The hose reel enclosure
and the upper base element can now rotate together as one unit.
In the retracted position, the latches 230 do not engage the lowermost
horizontal flanges of the hose enclosure. The hose reel enclosure
can now be removed from the upper base element. Since the hose reel
enclosure is relatively hollow, as illustrated in U.S. Pat. No.
6,742,740, latches 230 are readily accessible. Other conventional
fasteners, not shown, could be utilized in place of latches 230.
[0047] FIG. 16 illustrates a further embodiment wherein rollers
506 are employed as the bearings. The rollers are held in position
by sockets 508 which provide a support for the axis of roller 506
to rotate in. These sockets are positioned in a substantially circular
pattern on the top surface of the lower base element 504. A substantially
circular track (not shown) is located on the underside of the upper
base element 502 in alignment with the circular pattern of rollers.
Since the rollers do not allow for movement in a direction transverse
to the direction of rotation, there is practically no horizontally,
transverse movement of the upper and lower base elements with respect
to each other.
[0048] FIGS. 17-19 illustrate the unique feature of the invention
wherein a storage area is provided for stakes 222. Channels 240
are provided around the periphery of the underside of lower base
element 204. Retainers 242 are located in the central portion of
the channels substantially midway between the ends of the channels.
The retainers are provided with an aperture 244 for the receipt
of a stake 222. The lower portions of the channels are provided
with a plurality of raised supports 246 which together with the
retainers 242 function to hold the stakes in place during shipping
and storage after the stakes have been removed from apertures 224.
The supports are formed with two raised portions 248 and 250. They
are of different heights. The taller portion 250 is located closer
to the mid-portion of the channel 240. The top of the stake is located
in between the portions 248 and 250, as shown in FIG. 19. The lower
tip of the stake rests on portion 250 during shipping, as shown
in FIG. 19. The retainers 242 exert a downward pressure, as seen
in FIG. 19, on the stake 222. Supports 246 exert an upward pressure
on the stake. In addition portions 248 and 250 provide support for
the top of the stake so it cannot move longitudinally in channel
240. The combination of these forces enable the stakes to be frictionally
held in their storage positions in channels 240.
[0049] As will be appreciated by those skilled in the art from
a study of the figures and the above description, the base members
200, 300, 400, and 500 are formed primarily from molded components.
In a present form, the base members 200, 300, 400, and 500 are formed
primarily from high density polyethylene (HDPE) using an injection
molding process. Those skilled in the art will recognize that there
are various other materials that can be used to form the base members
200, 300, 400, and 500 components and various other processes by
which the components can be made, which other materials and process
are within the scope of the present invention.
[0050] All patents and publications mentioned in this specification
are indicative of the levels of those skilled in the art to which
the invention pertains. All patents and publications are herein
incorporated by reference to the same extent as if each individual
publication was specifically and individually indicated to be incorporated
by reference.
