<p>1,186,709. Locks. COMPAGNIE INDUSTRIELLE DE MECANISMES. 13 Dec., 1967 [16 Dec., 1966; 29 Nov., 1967], No. 56587/67. Heading E2A. A fastening device for a door or the like comprises a ball or roller 1 which is engageable successively in two consecutive recesses 7, 8 in a striking plate 9 to provide safety fastening and complete fastening of the door and a spring urged rod 4 urges the ball or roller towards the fastening position. The ball 1 is movable in a recess in a slider 3 and is retained in fastening position by a pivoting cylindrical abutment 11 which is rotated by actuating a push button 15 to bring a flat surface on the abutment opposite the ball to allow the ball to move against spring action and to allow the door to open. The edges of the striking plate may be inturned to prevent the fastening bursting open inadvertently in a crash. In another embodiment the roller is supported by trunnions engaging, with play, recesses in the fastening casing. The roller is retained in fastening position by a pivoting arcuate member which is urged by a spring to engage the roller. The casing is moulded from plastics and has an integral return spring for the roller and has protuberances for guiding the striking plate. The striking plate engages behind a base plate of the fastening casing to prevent the door bursting open inadvertently. The striking plate has a resilient end of travel abutment 19 for the slider 3.</p> |
