The present invention provides a resistant lock for locking doors, having a locking mechanism that enable locking the door in any direction without any modification or adjustment thereof, and that provide improved security.

The present invention relates to a security lock for vehicles, especially for the cargo compartments of lorries or vans, but also usable on other doors. The lock system uses a clamp having two halves or plates such that same hold a bolt, increasing the contact area in the event of a possible attack or leverage, and, if the surface of the vehicle becomes deformed, the two halves jam the bolt, further increasing security and reducing the possibility of opening. Using this invention, the system of inside opening by means of a cable is eliminated. Now, opening from the inside is performed by rotating a shaft or handle perpendicular to the surface of the vehicle, preventing the vehicle from being accessed from the outside.

One embodiment of an improved mechanism for operating a gate latch lever has a flexible line extending between two handles, one of which is connected to a gate latch lever (115). A portion of flexible line (107) is sheathed inside a coil spring (108) and traverses through a hole (112) bored horizontally through a gatepost (118). One end of the coil spring is attached to an anchor whose flange portion (105) prevents the coil spring from slipping through the gatepost hole. The other end of the coil spring is attached to the flexible line by a clamp (109). Thus, one can open the gate latch lever using one of the handles positioned on either side of the gatepost, and the tension of the coil spring returns the gate latch lever to its closed position automatically. Other embodiments are described and shown.
