The internal lock (4) has a bolt which is maintained in the extending locked position by a spring (7). The bolt (2) for the first lock (1) has a driver (3) which when the bolt is moved to its locked position causes the slide (8) to move to engage with the internal lock position blocking it in its locked position. The slide is subjected to spring force which attemps to push it out of engagement with the bolt (5) for the internal lock. It is coupled to an internal operating component (12) which can push and out of engagement with theThis operating component has a driver part (13) with which the main driver in the first lock bolt can come into effect when its bolt moves towards the locked position. The operating component is bent angularly, its one arm (13) forming the driver part, whilst its other amt (14) is controlled for straight-line movement at right-angles to the direction of displacement of the slide. |
