<p>1,032,304. Locking devices. V. CORNARO. June 5, 1964 [Oct. 3, 1963], No. 23516/64. Heading E2A. A locking apparatus for a container for valuables comprises a lock 5 disposable in and removable from a wall portion 1 of said container in the unlocked condition of the locking apparatus, and a locking bolt 14 carried by said wall portion, said lock comprising a housing and a locking bolt actuating mechanism, said locking bolt being displaceable by said mechanism into a locking position only after insertion of said lock in said wall portion. In the embodiment shown the wall portion is the door 1 of the container with a recess 3 for receiving the lock actuating mechanism 5, the mechanism being held in place by a leaf spring 6, a shoulder 7 of which engages an opening 8 in the rear wall 1b of the door. The element 10 comprises a slide member which is displaced vertically out of the housing 4 by means of a key. In the upper part of the door there is a bolt 14 displaceably supported for vertical upward movement within a sleeve 15. The bolt has a shoulder 17 which bears against a door ledge 16 in its lowest position and a surface 14a which bears against the upper surface 10a of the slide member 10 so that on moving the member 10 upwardly the bolt 14 is simultaneously moved upwardly to protrude from the door wall into an opening in the frame of the door. During unlocking the slide member 10 is pulled downwardly allowing the bolt 14 to be withdrawn into the door under its own weight. In another embodiment the lock actuating mechanism has a further bolt which co-operates with the slide member 10. The slide member 10 is formed with an inclined slot in which a cylindrical pin rigidly connected to the additional bolt slides so that when the slide member extends the bolt 14 it also extends the bolt 23 (Fig. 3, not shown). There may also be provided at least one additional bolt in the door preferably moving vertically but extending from the bottom of the door. The two bolts may be operated simultaneously by the horizontal movement of a double wedge member, a toggle device the two links of which are connected to the slide members or a rotatable cam disc which co-operates with rollers on the inner ends of the bolts.</p> |
