Abstract

1,159,737. Pin tumbler lock mechanisms. VIRO INNOCENTI S.p.A. 6 Sept., 1967 [6 Sept., 1966; 3 May, 1967], No. 40816/67. Heading E2A. A pin tumbler lock mechanism comprises a housing 1, a plug 2 rotatably housed inside the housing, a keyhole in said plug, a number of spring-urged pin tumblers 10 housed inside a corresponding number of aligned bores formed in the cylinder and the plug and positioned so as to coact with depressions formed in at least one edge of a key whereby when the key is inserted into the plug, the pin tumblers are moved so as to permit the plug to be rotated, two additional rows of pin tumblers being provided in the plug and housing .and positioned to coact with corresponding depressions formed in the opposite sides of the key. In the construction described the pin tumblers of the two additional rows are not disposed opposite each other but are axially offset. The axes of the two additional rows either lie in a diametral plane of the plug or in a chordal plane of the plug. The key is made symmetrical about its centre line so that each edge is provided with depressions and there are two rows of recesses in each side this arrangement enabling the key to be inserted into the keyhole either way up. The plug is provided with a cam for actuating a bolt (not shown) and the housing and the plug can be made of sintered metal powder. In a modification also the lock mechanism can be provided with an additional row of pin tumblers engaging depressions in the opposite edge of the key to the pin tumblers 10.
