Locking device for sliding doors

The innovation relates to a locking device for sliding gates according to the preamble of claim 1.

In the known locking devices of the aforementioned type, a recess is made on the inside leg of the vertical U-rail and a flat iron is attached to this inside leg, which has an arched recess at the height of the recess, into which the hook-shaped bolt of the lock engages. However, this engagement is only guaranteed if the bolt and flat iron are precisely aligned with each other. However, this precise alignment is only guaranteed if, on the one hand, the sliding gate is guided precisely in its guide rails and the vertical U-rail is precisely aligned with the guide rails. If the assembly is not precise, it is possible to cause the bolt to disengage from the recess in the flat iron by applying pressure against the door leaf of the sliding gate, thus allowing the sliding door to be opened.

The task is to design the locking device in such a way that a simplified assembly of the sliding gate is possible without compromising the safe functionality of the locking device.

This problem is solved with the features of claim 1. Advantageous embodiments can be found in the subclaims.

Examples of embodiments are explained in more detail below using the drawing, which shows a perspective view of the sliding gate in the area of the locking device.

When the term sliding gates is used below, it also applies to folding gates.

A vertical lock board runs at a slight distance from the end 1 of the door leaf 2

3. The lock 4 is embedded in the lock board 3. This lock 4 has a hook-shaped bolt 5.

The end 1 of the door leaf 2 engages in a vertical U-rail 6 in the closed state. This U-rail has a leg 7 on the inside of the gate. The lock 4 is arranged offset to the inside of the gate with its vertical axis 8 formed by the bolt 5 relative to the leg 7 on the inside of the gate. In the closed state, the bolt 5 is therefore at a distance from the leg 7 on the inside of the gate.

An angle iron 9 is attached to the U-rail 6, which has a vertical leg 10 running at right angles to the leg 7 on the inside of the gate. This leg 10 abuts the front edge of the leg 7 at right angles. At the level of the bolt 5, the leg 10 is provided with a recess 11. In the closed state, the bolt 5 engages in this recess 11 and engages behind it. The horizontal dimension of this recess 11 is larger than the horizontal dimension of the bolt 5. This allows relatively large tolerances between the U-rail 6 and the position of the lock 4 determined by the door leaf 2 to be compensated.

In the embodiment shown in solid lines, the leg 10 is part of a U-shaped angle iron 9, consisting of the side legs 10, 12 and the middle leg 13. The middle leg 13 runs parallel to the leg 7 of the U-rail 6. The leg 12 is longer than the leg 10 and rests against the middle leg 14 of the U-rail 6. It has two vertically extending slots 15, via which it is screwed to the leg 6 in a height-adjustable manner.

According to a further embodiment, the angle iron 9 can be L-shaped, consisting of the previously described leg 10 and a further leg 16, which rests against the leg 7 on the inside of the gate. The leg 16 is then also screwed to the leg 7 via elongated holes. In this embodiment, the recess 11 can be open towards the inside of the gate, but is preferably delimited by a vertical web formed by the leg 10.

In a known manner, the door leaf 2 is guided in a horizontal guide rail 17 on the floor. In order to ensure precise guidance of the door leaf 2, particularly in the area of the end 1, the lock board 3 is extended in the direction of the guide rail 17 and carries two rollers 18 with a vertical axis of rotation that engage in the guide rail 17.

In the U-shaped angle iron 9, the recess 11 is laterally limited on the one hand by the leg 7 on the inside of the gate and the middle leg 13. In the L-shaped angle iron 9, the recess 11 is limited on the one hand by the leg 16 and on the other hand by the aforementioned vertical web.
