[0001] The present invention relates to a sliding gate consisting of a frame with at least
one post, that is brought in between two ground-connected stakes when the gate is
closed.
[0002] Such sliding gates are well-known and are a.o. described in the German Gbm 8906344
and the European patent applications 134.824, 711.898 and 792.969.
[0003] It is extremely important that a closed sliding gate can be firmly locked. Indeed,
when the interlocking mechanism and/or the closing devices of the gate are opened
or broken, it is relatively simple to completely open the gate or even wrench it.
[0004] The invention intends to provide a new kind of sliding gate, allowing to firmly interlock
the gate when closed.
[0005] To that end, for the aforementioned kind of gate, the invention proposes that the
post and both stakes are equipped with integrated tubular elements that align when
the gate is closed, and that an interlocking bar can be slid through the aligned tubular
elements in the post and both stakes to interlock the gate when closed.
[0006] Preferably, the post and stakes are hollow.
[0007] It is an advantage that the post and both stakes are equipped with at least two sets
of integrated tubular elements, that align when the gate is closed, and that at least
two interlocking bars can be slid into the two sets of tubular elements to interlock
the gate when closed. It is desirable that the ends of the two interlocking bars are
interconnected by a cross element, so as to form a U-shaped interlocking device, and
that the cross element is close to the adjoining stake when the U-shaped interlocking
device is closed.
[0008] In a preferred embodiment, the interlocking bar or the U-shaped interlocking device
is equipped with closing devices, that concur with the closing devices in the adjoining
stake when the interlocking bar or the U-shaped interlocking device is closed. Hereby
it is advisable to equip the adjoining stake with a U-shaped safety device so that
the cross element of the U-shaped interlocking device clicks into this safety device
when the U-shaped interlocking device is closed.
[0009] In a further preferred embodiment, at least one interlocking bar and the adjoining
stake are provided with concurring means to connect the interlocking bar to the stake
so that it cannot be removed.
[0010] The invention will be explained in detail in the following description by means of
the accompanying drawings.

the gate is closed, in which a post of the gate is brought in between two ground-connected
stakes ;

when the interlocking device is opened ;

stake, equipped with means to connect the interlocking bar to the stake so that it

[0011] Figure 1 represents a view in perspective of a sliding gate 1 according to the invention
when the gate is closed. The sliding gate 1 consists of a frame 2 with railings 3
at regular intervals and the necessary drive and guide wheels 4. The frame 2 consists
of at least one lower 5 and one upper 6 cross beam and two upright posts 7. Figure
1 clearly shows that the left-hand post 7 of the gate 1 is brought in between two
ground-connected stakes 8 when the gate 1 is closed.
[0012] Preferably, the post 7 and both stakes 8 are hollow, made of steel and present a
practically rectangular cross-section.
[0013] According to the invention, the post 7 and both stakes 8 are equipped with welded
tubular elements 9. When the gate is closed, the two tubular elements 9 of the stakes
8 mutually align and also align with the corresponding tubular element 9 in the post
7. The length of the tubular element 9 in the post 7 should practically be equal to
the depth of the post 7.
[0014] According to the invention, an interlocking bar 10 can be slid through the aligned
tubular elements 9 in the post 7 and both stakes 8 to interlock the gate 1 when closed.
[0015] In addition, Figure 1 shows that the post 7 and both stakes 8 are equipped with two
sets of integrated tubular elements 9, that align when the gate 1 is closed and that
two interlocking bars 10 are brought in the two sets of tubular elements 9 to interlock
the gate 1 when closed.
[0016] Figure 1 also shows that the ends of the two interlocking bars 10 are interconnected
through a cylindrical cross element 11 to form a U-shaped interlocking device 12 and
that the cylindrical cross element 11 comes close to the adjoining stake 8 when the
gate 1 is closed.
[0017] Figure 2 shows a side view of the opened U-shaped interlocking device 12 according
to the invention. Figure 2 uses the same reference digits as figure 1 to indicate
the same parts of the gate. The cylindrical cross element 11 of the interlocking device
12 is equipped with integrated closing devices 13, that concur with closing devices
14 in the adjoining stake 8 when the device 12 is closed. The cross element 11 is
also equipped with a handle 15 to facilitate moving the interlocking bars 10 in the
tubular elements 9 in the post 7 and the stakes 8.
[0018] Figures 1 and 2 also show that the stake 8 adjoining to the interocking device 12
is equipped with a welded U-shaped steel profile 16. When the U-shaped interlocking
device 12 is closed, the cylindrical cross element 11 is brought in the U-shaped profile
16. Therefore, the cross-sections of the U-shaped steel profile 16 and the cylindrical
cross element 11 are similar or in other words the U-shaped steel profile 16 functions
as safety device for the cross element 11 and the integrated closing devices 13 of
the U-shaped interlocking device 12. When the interlocking device 12 is closed and
the cylindrical cross element is brought in the U-shaped safety device 16, it is impossible
to wrench a chisel or similar object between the cross element 11 and the adjoining
stake 8 to break open the closing devices 13.
[0019] Figure 3 shows a longitudinal cross-section of an interlocking bar 10 according to
the invention, used to be slid in the tubular elements 9. Preferably, the interlocking
bar 10 and the corresponding tubular elements 9 have practically circular cross-sections,
that are adapted to one another or in other words the cross-section diameter of the
bar 10 is slightly smaller than the inner diameter of the tubular elements 9 in the
post 7 and the stakes 8. As figure 3 clearly shows, the bar 10 has a notch 17 over
a part of its length. The purpose of this notch 17 will be explained below in the
description of figure 4.
[0020] Figure 4 represents a view in perspective of a part of an interlocking bar 10 and
the adjoining stake 8, equipped with means to connect the interlocking bar 10 to the
stake 8 so that it cannot be removed. To this end, the protruding part 18 of the tubular
element 9 in the stake 8 has a cross groove 19 in which fits an integrated cross plate
20, that concurs with the longitudinal notch 17 in the bar 10. When the cross plate
20 in the groove 19 is fixed to the stake 8, it is impossible to remove the bar 10
from the tubular element 9 as the end 21 of the bar 10 is stopped by the cross plate
20.
