[0001] The subject of the invention is a sliding gate, particularly a fire gate. Such gates
are intended mainly for enclosing space and preventing fire from spreading. In the
case of gates crossing evacuation routes, the gate wing is provided with at least
one passage door.
[0002] The passage door installed in the gate should be provided with a safety measure preventing
door opening during motion - opening/closing the gate wing, as well as when the gate
wing remains open. The passage door may be opened only when the door is closed.
[0003] A solution according to the invention was developed in order to meet the described
requirements.
[0004] A sliding gate including a housing with an entry pocket, placed within the housing
of the moving rail and a gate wing with the passage door and a drive system,
characterised in that it is equipped with a mechanical locking system located in the top part of the gate,
above the passage door, formed by a body made of an closed profile, a tensioning spring
attached to the housing at one end and connected to the bolt at the other end, a linkage
provided as a steel bar, in the closed position of the gate resting on the housing
at one end and holding the bolt in the unlocked position at the other end, a linkage
guide made of a closed profile, fixed within the body, a connection socket with a
width corresponding to the bolt thickness, located in the top part of the passage
door wing, or with an electric locking system located on the gate wing, including
an electric bolt with a latch located within the passage door, a battery providing
power supply through the electric bolt wires and a latching socket provided at the
edges of the door wing.
[0005] The locking system is preferably located within the gate wing, in the area of the
door wing, on the side of the door lock.
[0006] The body preferably has a rectangular or a circular cross-section.
[0007] The bolt preferably has the shape of a rectangular plate with one tapered edge.
[0008] The linkage preferably has the shape of a circular or a rectangular cross-section
steel bar.
[0009] The guide preferably has the shape of a closed profile with a circular or a rectangular
outline. The cross-sectional dimensions of the linkage are preferably adapted to the
internal dimensions of the guide.
[0010] The electrical locking system couples the electric bolt with the door wing. Locking
is the condition prevalent when the electric bolt is not supplied, which is usually
the case during a fire. The electric bolt then holds the latch inside the latching
socket. The passage door is locked when the gate wing is moving. Unlocking takes place
when the gate wing is closed, by switching the power supply on. The electric bolt
unlocks the latch from the latching socket and the door wing may be operated. Locking
using the electrical bolt is used usually when the gate is provided with a power supply
system.
[0011] The design of the locking system is simple to make and operate.
[0012] The locking system enables simple coupling between the passage door and the gate
wing when the gate is moving and holding the bolt in the unlocking position when the
gate is closed. The intermediate door secured against opening during gate motion significantly
increases operational safety of the sliding gate.
[0013] The subject of the presented in an embodiment in the drawing, in which Fig. 1 - presents
the gate in its open position, Fig. 2 - presents the moving gate, Fig. 3 - presents
the gate in its closed position, Fig. 4 - presents a front view of the mechanical
locking system, partially in a cross-section, Fig. 5 - presents a side view of the
mechanical locking system, Fig. 6 - presents the gate wing with the door wing locking,
Fig. 7 - presents the gate wing with the door wing unlocking in the closed position,
Fig. 8 - presents the gate with the electrical locking system, Fig. 9 - presents the
door wing locked with the gate wing using an electrical locking system, and Fig. 10
- presents the door wing and the gate wing in the unlocked position.
[0014] The sliding gate is fixed inside a housing. It is built out of a gate wing
1 suspended on a moving rail
2 and intermediate door
3 placed in it, with a door wing
4, a drive system and a locking system. The mechanical locking system 5 is located in
the top part of the gate, above the passage door 3, in the corner area of the door
wing 4, on the side of the door lock. The locking system
5 comprises of a body
6 in the shape of a closed profile, fixed to the gate wing 1, a bolt
7 in the shape of a rectangular plate with one tapered corner, installed and rotating
on a pin 8 fixed in the body 6, a tensioning spring 9 fixed to the body 6 at one end,
and on the other end - connected with the bolt 7, a linkage 10 in the form of a steel
bar, sliding inside a guide 11 in the shape of a closed profile, fixed to the interior
of the body 6 and a latching socket 12 placed in the top part of the door wing 4.
The latching socket
12 cooperates with the bolt 7. During motion - opening or closing of the gate wing 1,
the bolt 7 passes through the latching socket 12 and blocks the opening of the passage
door 3 during gate motion.
[0015] In the closed position of the sliding gate, the linkage 10 rests at one end against
the housing and the other end holds the bolt 7 in a position moved away from the latching
socket 12, such that the door wing 4 is released and may open. On the other hand,
when the gate wing 1 starts moving from the closed position of the gate, the end of
the linkage 10 moves away from the housing and the linkage 10 will move due to the
pressure of the bolt 7 caused by the tensioning spring 9, causing the bolt
10 to move onto the latching socket
12 and locking the door wing
4. The length of the linkage
10 and of the body
7 depends on the dimensions of the wing gate 1 and of the passage door
3 placed in it. The electrical locking system 13 is placed on the gate wing 1. It includes
and electric lock 14 with a latch 15, a battery 16 powering the electric lock 14 and
a latching socket 16 installed on the edges of the door wing 4.
[0016] The door wing 4 becomes locked with the gate wing 1 when the electric lock 14 is
not energised. This is significant during a fire, when the power supply system is
inoperational. Unlocking takes place when the power supply is switched on.
This improves safety during the use of sliding gates.
[0017] The subject of the invention has been presented in an embodiment. In the case of
low gate wings and lack of space preventing the locking system 5 from being placed
in the top part of the gate, the locking system 5 may be placed vertically.
[0018] This solution may also be used with gates with low gates, by placing the locking
systems in a horizontal position.
