Description

Anti-theft lock

The present invention relates to a lock anti-theft that can be used on motor vehicle doors, especially in delivery vans and trucks, but also in any door where its placement is possible.

Various types of locks intended for such use are known. Thus, the document ES 1 057 040 U, of the applicant itself, describes an anti-theft lock consisting of two robust parts that can be coupled to the two doors of a vehicle. The first piece has a rod inside, manually movable parallel to the plane of the doors, which can be inserted into the second piece, where it is retained by an anchoring body that rotates when a lock is operated. In this way, both pieces are in solidarity and with them the doors to which they are attached, preventing their opening. However, such a solution leads to the rod being accessible from the outside, being able to be subject to a saw attack until causing its
cut.

In order to solve the problem described, has developed the anti-theft lock of the invention. This It comprises a stem that has a recess in its surface, joined perpendicular to a first fixed door or frame. A body Main, joins a second door. This main body It has a blind hole that can be received inside the stem, which covers and protects in closed position, and is equipped with a lock with removable key attached to a cylinder lock that in one position plays in the stem recess immobilizing it, while in another position it presents in front of the shank a recess that allows to freely insert and remove the blind drill stem of the main body.

In this way, the rod is not accessible when the lock is in the closed position, being protected by the main body against external attacks.

To complement the description above, and in order to help a better understanding of the characteristics of the invention, a description will be made detailed of a preferred embodiment, based on a set of drawings which are accompanied by this descriptive report, and where, with indicative and non-limiting nature, what has been represented next:

Figure 1 shows an elevation view of the lock of the invention.

Figure 2 shows a plan view of the lock of the invention.

Figure 3a shows a schematic section by line III-III of figure 2, with the lock in closed position.

Figure 3b shows a schematic section by line III-III of figure 2, with the lock in open position.

As can be seen in figures 1 to 4, the anti-theft lock of the invention consists of a rod (1) cylindrical, integral with a first door (2), which has a recess (3), cancel.

On the second door (4), a body is fixed main (5) that has a blind hole (6) capable of receive inside the rod (1), and that is equipped with a lock (7) provided with removable key, which when activated rotates a locking cylinder (8), which has a recess (9), circular sector, facing the rod (1).

The operation of the lock is the next. Once the doors and the rod (1) are closed inside the blind hole (6) of the main body (5), the lock (7) to rotate the locking cylinder (8) of such so that the recess (9) is on the opposite side of the recess (3) presenting the stem (1). See figure 3a. In this way the stem (1) is immobilized.

Actuating the lock (7) can now be done rotate the locking cylinder (8) an angle of 180º to a position as schematically represented in figure 3b, in which the recess (9) is faced with the rod (1) and this one is released, being able to be extracted from the blind hole (6) of the main body (5), which allows to open the second door (4) in the direction indicated in figure 2.

As for the realization of the lock anti-theft of the invention will be apparent to the expert in the matter a series of alternatives and variants to adapt the design to the means of production available. So the body main (5) will be preferably made of aluminum for hinder its cut with radial, but any suitable material. Likewise the fixation of the rod (1) and the main body (5) to the doors (2) (4) will be made preferably by screws (10) threaded on inserts rivets (11), taking the precaution of destroying the heads of the screws (10) after assembly, but it would be equally suitable use any equivalent means of attachment, such as rivets, or hidden screws threaded on the rod (1) and the body main (5) from inside the doors (2) (4).

Claims (3)

1. Anti-theft lock intended to secure the closure against a first door (2) or fixed frame, of a second door (4), characterized by comprising:
