Abstract:
An anti-tamper locking assembly for locking a position of a block, comprising:an electrical moving means, selectively activated by an electronic circuit, for moving a pin that is normally maintained in a first position in an un-energized state of said moving means to a second position in an energized state of said moving means, said pin having an overhanging portion that extends laterally from at least one side of said pin;a block mounted to move along a path passing transverse to an axis of said pin;said block having a pin blocker extending outward from a side of said block;said block having at least one spring-arm mounted thereto, said spring-arm being normally maintained in a first position near said axis of said pin and being moveable in a direction away from said axis of said pin;wherein in an un-energized state of said moving means a) when said block is moved along said path to an adjacent position whereat said pin is adjacent said pin blocker, said overhanging portion abuts said pin blocker and a surface of said spring-arm is positioned to block said overhanging portion to prevent said pin from being forced to a position wherein the overhanging portion does not abut said pin blocker, and wherein in an energized state of said moving means a) said overhanging portion is moved to a position whereat when said block is moved along said path, said overhanging portion abuts said spring-arm to cause said spring-arm to move laterally away from the axis of said pin and b) said overhanging portion is positioned so as to pass said pin blocker when said block is moved along said path past said adjacent position.
