Abstract

A combination lock comprises a plurality of buttons 12, a locking member 3 and code member associated with each button. The code member is mounted between a code positioning member 6 and a movable member 5 and includes a code plate 81 and code pin 82 protruding through an elongate slot in the movable member and movable between two lateral positions to determine the unlock code. The locking member 3 includes a blocking protrusion 33 and an inclined surface (31, fig. 10) cooperating with the button such that pressing the button moves locking member sideways such that the blocking protrusion either obstructs the code rod 82 or is offset from the code rod. When the correct code is entered the stopping blocks 33 of the locking members are offset from the code rods 82 and upon operating knob (14, fig. 1) movable member 5 is allowed to move; if an incorrect code is entered blocking protrusions 33 obstruct code rods 82 preventing movement of member 5 and stopping operation of the knob. A reset member 2 includes hooks which retain locking members 3 once pressed and is released either by rotation of knob or pressing of a reset button 13.
