Abstract:
1. A quick release assembly, comprising: a receiver having at least one protrusion, the receiver having an opening having an elongate cross section; a body that is configured to be received within the opening of the receiver, the body inserting into the receiver in an insert direction, the body comprising four body contact surfaces and one or more latches, each latch corresponding to a respective protrusion of said at least one protrusion on the receiver, and each latch being rotatably mounted and comprising a rounded outer surface that is biased in a latch direction so that a portion of the rounded surface latches behind one of said at least one protrusion when the body is received within the receiver, the four body contact surfaces being tapered outward from an insert end of the body; the receiver having four receiver contact surfaces that align against the four body contact surfaces when the body is inserted into the receiver, the four receiver contact surfaces being tapered in a similar manner to the four body contact surfaces to cause two-directional wedging of the body in the receiver such that play is eliminated in both a fore to aft direction and a left to right direction when the body is inserted into the receiver, the fore to aft direction, left to right direction, and insert direction being mutually and substantially perpendicular; and a release mechanism for releasing said one or more latches from the protrusions wherein: the body is inserted into the receiver moving in a direction from a first end toward a second end; each said one or more latches is rotatably mounted about a rotational mount and the rounded outer surface of the latch defines a cam surface having an outward end and an inward end, the latch moving in a direction from the inward end toward the outward end to latch a respective protrusion; and for each latch, a portion of the rounded outer surface of the latch extending beyond a respective protrusion in the latch direction slants downward toward the rotational mount and toward the second end from the inward end toward the outward end so that the distance from the cam surface to the rotational mount decreases from the inner end to the outward end of the cam surface.
