Description
[0001] The invention relates to a foot bolt of a sideways movable
sliding door, a wall, a sliding window or a similar element, the foot
bolt comprising a part locking the element in the base, such as a
pin fitting in the hole in the base and also comprising a counterpart
in the next element movable beside it, in which counterpart the part
in the edge of the preceding element can be fitted so that the adjacent
elements get sideways interlocked and that on moving the elements
in the opposite direction pushing the last brought element from beside
the preceding element opens the locking of the preceding element from
the base.
[0002] Previously known are foot bolt constructions as described
among others from U.S. patent publication 6108989, DE published
applications 4428718 and 19634390. In all of them as solution an
automatic foot bolt is presented always placed in the move preceding
element in its edge against which the next element is moved. The
foot bolt has a pin fitting in the hole in the base, the sliding
wall of which pin moved as the next contact makes by means of different
gears sink down into the hole in the base. The solutions include
that on moving walls away the removal of the preceding element releases
the foot bolt pin in the next element up from the hole in the base.
[0003] Such a solution is easily produced but in practice the solution
works only in connection with most accurately controlled elements,
for which the holes in the base are just in positions according
to the elements. In these solutions pushing the next element as
extension of the preceding one the locking of the edge of the preceding
element takes place only when the next element is pushed into contact.
Accordingly, there is then nobody to secure that the pin takes its
place in the hole in the base.
[0004] The weakness of these solutions is that on moving high elements,
such as those of 2,5-3 meter height, while only from their upper
edge in slide suspension, the elements do not at all hang by themselves
so accurately that in the bottom edge a pin, for instance with a
diameter of about 10 mm would hit a hole with a diameter of about
15 mm. In spaces where such closing walls are used there are often
so much air flows that the elements simply swing. Under those circumstances
it is impossible in the practice that automatic locking would work
nearly in ways corresponding to one another according to solutions
represented in the publications.
[0005] The aim of the invention is to produce a foot bolt, the
function of which is reliable, its locking quickly done and its
opening automatic, when walls are moved. The invention is characterized
in that the pin fitting in the hole in the base is meant to get
manually pressed with the foot into the hole, and the bolt construction
comprises a locking/release pin, which in the first stage is arranged
to lock the pressed-down pin in the hole in the base, and directed
towards the next element the pin has a bracket, for which there
is in the next element a counter-hole for interlocking and that
the locking/release pin is arranged to stick out from the element
edge so that it can with the next close beside the preceding brought
element be pushed into a pin releasing position, whereby he pin
is individually, for instance by a spring, arranged to get up from
the hole in the base, when the adjacent element is removed.
[0006] The advantage of the foot bolt according to this invention
is that when a separate wall is in its turn pushed to the position
intended for it, it can be controllably steered to its place and
at the same time simply stamp the locking pin down. The staying
put of the element is easily secured and the pin position is easily
seen, whether it has the possibility to get into the hole at the
time. In the solution you need not to bend, since locking, that
is stamping down the pin is most suitably done by foot. The next
element to be brought into contact tunes-up the foot bolt so that
it opens automatically, when starting to remove elements. The solution
according to the invention can be used both for small size elements
and especially for large ones.
[0007] In the following the invention is disclosed referring to
the enclosed drawing, where
[0008] FIG. 1 shows sliding fit glass elements from the side.
[0009] FIG. 2 shows fit glass elements, edge profile and the foot
bolt.
[0010] FIG. 4 shows the foot bolt from the side partly broken up.
[0011] FIG. 5 shows the foot bolt cut with the pin up.
[0012] FIG. 6 shows the boot bolt of FIG. 5 cut from above
[0013] FIG. 7 shows the foot bolt cut with the pin down.
[0014] FIG. 8 shows the boot bolt of FIG. 7 cut from above
[0015] In FIG. 1 elements 1-3 installed by means of rolls to be
moved in the upper fixing rail, by means of which elements a broad
corridor space, for instance, can if necessary be closed. In the
bottom edge of the glass sheet there are edge strips 4 and 6 made
of aluminium. The elements are linked in order to form a uniform
wall.
[0016] In FIG. 2 the elements are shown diagonally, whereat also
in FIG. 3 profile form 6 of the bottom edge is shown, in the end
of which foot bolt 10 can be fitted. In the other end of profile
6 foot bolt 10 is fitted and in the other end is the profile-locking
end piece furnished with hole 9 fitted. When element 3 is moved
in contact beside element 2 the pin 12 of element 2 foot bolt gets
into hole 9 in the end of element 3. The downwards pin 11 of foot
bolt 10 is positioned in the hole in the bottom as illustrated also
in FIG. 1.
[0017] FIG. 4 shows the foot bolt construction schematically. The
upwards movable locking pin 11 is pushed into hole in foot bolt
10 hole and from the oblong hole 19 in the side of the body the
threaded head of the sideways directed bracket 13 is pushed towards
the pin and screwed into hole 17 in pin 11. For pin 11 a travel
distance determined by the oblong side hole 19 is formed. Spring
15 is placed inside body 10, whereat it strives by means of its
springback factor to keep pin 11 in upper position. Spring 15 is
fitted into its housing by means of a shaft (not shown), which is
pushed from hole 18 and runs through the spring eye. There is in
body 10 for locking/release pin 12 a hole fitted with respect to
the of hole pin 11 that they intersect partly. Spring 4 pushes pin
12 outwards and, furthermore, pin 12 has a thinning spot 16 so that
when the thinning spot is on the line of pin 11, pin 11 can move
vertically.
[0018] FIG. 5 is a crosscut view of body 10. Spring 15 keeps pin
11 up. The thinning spot is on the line of pin 11. When the element
is moved by pressing it by foot to its place in order to lock bracket
13, whereat pin 11 gets into the hole in the base and also remains
in the lower position, since pin 11 has been pressed so much down
that locking/releasing pin 12 has according to FIGS. 7 and 8 come
out a little pushed by its spring 14 and its pin portion of even
thickness has moved partly over pin That is why pin 11 remains in
lower position.
[0019] When the next element is brought closed beside the preceding
one, there is in the edge of profile 6 of the element to be the
brought a cover an a hole 9. The cover hits locking/releasing pin
12 and pushes it into the body, bracket 13 gets into position in
cover hole 9. When cover hole 9 is loose or slightly oblong lengthwise
bracket 13 and pin 11 can get up a little by the force of spring
15, and when thinning point 16 of pin 12 is now on the line of pin
11 this pin 11 gets up crosswise with thinning point 16 of pin 12
(oblong hole 9 allows raising) so much that it gets locked into
position that releases pin 11. Bracket 13 is still in hole 9 and
pin 11 is still in the hole in the base, whereby the element is
locked to the base at the foot bolt and both sideways and in moving
direction and even the other end of the element's lower edge is
locked sideways. The ends of the lower edge profile 6 of each element
have a hole 9 and cover in one end and foot bolt 10 in other end.
Foot bolt body 10 is most suitably formed to be pushed directly
into profile 6 according to FIG. 3.
[0020] When elements 1-3 are moved away in the opposite direction
the move of element causes that foot bolt 11 of the next element
gets up by force of the spring 15 immediately Thus the next element
is automatically opened from locking and can be moved away as the
other ones left behind.
[0021] By means of the foot bolt solution the moving and locking
of elements to their places can be reliably carried out, since the
element is handled and controlled manually till the locking. Locking
can in no way be opened from the outside of the wall and no steering
rails need to be arranged for the elements, only a series of holes
on the line and at proper distances from one and other.
