1. A mechanism for engaging an item of portable equipment to a belt clip system in which the portable equipment is provided
with a first protrusion comprised of a short column and a flange, and the belt clip includes a plate surface formed with an
engaging part composed of frames arranged at both sides and a front plate formed with a substantial U-shaped recess having
a released side and a fitting limit part, wherein the short column may be guided by the recess at said belt clip to cause
the flange to be fitted to and held at the engaging part, thereby said portable equipment is removably attached to said belt
clip, wherein the improvement comprises:
said flange of said portable equipment having a disc and a continuous annular frame formed at the circumferential edge of
the disc defining a locking recess with an outwardly facing end surface and radially inwardly projecting cam engaging protrusion;
a resilient claw cantilevered in relation to said plate surface and projection along a portion of said plate surface, said
claw having a slanted engagement surface corresponding to said released side of said recess and at least one slanted disengagement
surface adjacent to said engagement surface, said engagement surface being operable to abut against said annular frame in
an area opposing an inwardly directed surface of said cam engaging protrusion and said annular frame under a state in which
the flange at said portable equipment substantially reaches said fitting limit part of said engaging part and said claw is
in said locking recess, and said disengagement surface being operable to slide over said cam engaging protrusion as said first
protrusion is rotated to drive said claw out of said recess whereby said portable equipment may be removed from said belt
clip.
