VEHICLE LOCK

Abstract

A vehicle lock is provided for doors with a moving leaf. The vehicle lock includes a strike plate attached to a passive element, to which a bolt attached to the moving leaf is connected. One or more perpendicular spindles, along which the strike plate slides, emerge from the passive element.

Claims

2. The vehicle lock, according to claim 1, wherein at least one spindle (6) includes a spring (7) to push the strike plate (6) against the passive element (2).

3. The vehicle lock, according to claim 1, wherein it consists of an inclined plane (8) in the area of contact between the bolt (3) and the strike plate (1) on the part furthest from the passive element (2).

4. The vehicle lock, according to claim 3, wherein it also consists of an inclined plane (8) in the area of contact between the bolt (3) and the strike plate (1) on the part nearest the passive element (2).

5. The vehicle lock, according to claim 2, wherein it consists of springs (7) in at least one spindle (6) on both sides of the strike plate (1).

6. The vehicle lock, according to claim 1, wherein the strike plate (1) has a fixed part (1) attached to the passive element (2), and a moving part on the spindles (6).

7. The vehicle lock, according to claim 1, wherein the spindles (6) are attached to the fixed part (1) of the strike plate (1).

8. The vehicle lock, according to claim 4, wherein it consists of springs (7) in at least one spindle (6) on both sides of the strike plate (1).

METHODS OF EMBODIMENT OF THE INVENTION

[0024] There follows a brief description of a method of embodiment of the invention, for information purposes only.

[0025] In FIGS. 1A and 1B, the different positions of a lock are shown according to a particular embodiment. This includes a strike plate (1), which is attached to a passive element (2) such as the frame of an industrial or commercial vehicle. If it is a double-leaf door, the strike plate (1) is attached to the leaf that opens second, which is in turn securely fixed to the frame.

[0026] Alternatively, the lock in FIGS. 1-2 has a bolt (3), such as a latch, which slides along a locking body (4) attached to the moving leaf (5). The bolt (3) may be connected to a spring which pushes it towards one end of the locking body (4). The bolt (3) is connected to a controller so that the user can open the lock. Any known controller may be used, including electromechanical elements. The system may have a controller locking element, in the form of a lock, although this is not essential for the invention.

[0027] The bolt (3) may be moved by rotation or any other type of movement, without necessarily having to be a sliding movement. FIG. 3 shows an example of a lock with a rotating movement.

[0028] FIG. 4 shows an additional embodiment in which the bolt (3) has a groove which holds the strike plate (1), in this case a rod with a neck that fits into the groove. The bolt (3) shown is a sliding bolt, but in the invention a scissor mechanism may also be used to hold the strike plate (1). In this case, the strike plate (1) is made up of two parts, with only the part furthest from the passive element (2) sliding along the spindles (6). The other part is a fixed part (1) attached to the passive element (2). As can be seen, this embodiment only requires one spindle (6).

[0029] As is made clear in FIGS. 2-4, the strike plate (1) is mounted on spindles (6), with enough play to allow the strike plate (1) to move along them, normally in a direction perpendicular to the surface of the passive element (2). A spring (7) in at least one spindle (6) pushes the strike plate (1) against the passive element (2). In FIG. 3 only, the strike plate (1) has not separated from a fixed part (1) from where the spindles (6) and a moving part emerge.

[0030] The bolt (3) and strike plate (1) have an inclined plane (8) in the contact area. This inclined plane (8) may be on one or both elements. It is situated so that the area of contact between the bolt (3) and the strike plate (1) is on the part furthest from the passive element (2). If the moving leaf (5) is perfectly coplanar with the moving element (2), the bolt (3) will go straight into the space in the strike plate (1). However, if they are not coplanar, they will collide with each other in the area of the inclined plane (8). This causes the strike plate (1) to move along the spindles (6) as it is kept apart by the inclined plane (8), as can be seen in FIG. 2. Once it has been separated, the bolt (3) fits perfectly into the strike plate (1). The springs (7) ensure that this support does not move and that the strike plate (1) returns to its initial rest position when the door is open.

[0031] The inclined plane (8) may also be in the area of contact between the bolt (3) and the strike plate (1) on the part nearest the passive element (2). This solution is particularly useful if the spindles (6) have springs (7) to centre the strike plate (1). In other words, they have springs (7) on both sides of the strike plate (1), enabling movement in both directions to ensure that it stays centred. This solution allows for play in any direction. In
