Abstract:
A tamper-resistant locking mechanism for restricting access to the interior space of a rigid enclosure, comprising:a star cam twister defining a longitudinal axis, said star cam twister defining a first axially extending member having a first end and a second end disposed opposite said first end, said first end of said star cam twister being configured with an axially extending first opening having a star-shaped transverse cross-sectional shape, said second end of said star cam twister being configured with an axially extending first cam member, said star cam twister being rotatable, said cam member being configured for engaging a cam receiving member;a spin bushing, said spin bushing being rotatable, said spin bushing defining a second axially extending member having a first end and a second end disposed opposite said first end, said spin bushing defining an axially extending second opening having a transverse cross-sectional shape that can receive a key therein and allow said key to pass therethrough to be received within and held non-rotatably by said star-shaped cross-sectional shape of said first opening of said star cam twister, said first end of said spin bushing being disposed apart from and facing said first end of said star cam twister said disposition of said spin bushing with respect to said star cam twister defining an axial gap between said spin bushing first end and said star cam twister first end, said axial gap preventing said star cam twister from contacting said spin bushing; andan axially extending latch member having a first end configured to selectively engage and disengage a hook member, said latch member having a second end being configured with a cam receiving member for receiving said first cam member.
