<p>A quick disconnect assembly is disclosed for joining two members. The assembly is comprised of two circular steel bushings, a cylindrical steel pin and a steel spring ring. The bushings include axial circular openings and are each disposed in one of the legs of the first member so that they are axially aligned. The pin includes an annular groove in which is disposed the spring ring. The second member has a circular bearing at one end which has a circular opening extending axially therethrough. Connection of the first and second members is accomplished by positioning the second member between the legs of the first member so that the bearing opening is in axial alignment with the bushings openings. The pin is then inserted into the three aigned openings from one end. Insertion is aided by chamfers which help to compress the spring ring. When the pin is fully inserted, the spring ring expands because of its resiliency and abuts against an annular shoulder in the opening of the first bushing to retain the pin in position. Disconnection is accomplished by pulling the pin out of the openings. Pin removal is impeded by the annular shoulder. A second annular shoulder in the other bushing acts to retain the pin in a partially withdrawn position.</p> |
