ABSTRACT:
A latch mechanism includes a cylindrically shaped rotating cam having a small radius portion and a large radius portion that are spaced from each other along a circumference of cylinder. A ball is seated against the cam. The ball is forced outward when it is seated in the small radius portion of the cam, and is allowed to move inward when it is seated in the large radius portion of the cam. A first hollow latch pin is provided, having an indentation at one point on the outer surface thereof into which the ball can seat. A second smaller size latch pin, also having an indentation in one point on the outer surface thereof into which the ball can seat, is insertable within the first hollow latch pin, to thereby allow multiple objects to be secured by the latch mechanism. A housing supports and facilitates movement of the cam, the ball and the two latch pins.
