Abstract
Abstract In the titled arrangement, a guide pin which is received by the track is assembled with a retainer with the assembly being carried by a pair of spaced-apart walls connected to the closure member and being axially displaceable relative thereto, the retainer including an arm adapted for selective engagement and disengagement with one of the two spaced-apart walls in accordance with the rotative position of the retainer to hold the assembly in an extended position with the guide member in the track, and to permit the assembly to be axially moved to a retracted position in which the guide member is out of the track.

208 words
An arrangement for supporting a closure member from a track, comprising: a guide member and retainer assembly, said guide member having one end adapted to be received by said track, and its other end received by said retainer; spaced apart inner and outer walls connected to said closure and lying in planes generally parallel to said track and generally normal to the axis of said guide member and retainer assembly, said walls having registering holes therein to receive said assembly in axially displaceable relation therein; means carried by said retainer for selective engagement and disengagement with said inner wall in accordance with the rotative position of said retainer to establish one and another axially displaced positions of said assembly relative to said walls; said engaging means carried by said retainer comprises an arm projecting generally radially relative to the axis of said retainer; and said inner wall includes a slot through which said arm is movable in the axial displacement of said assembly relative to said walls, so that said arm is axially movable, with said retainer, from a position between said walls for said engagement with said inner wall, to a position on the inner side of said inner wall for said disengagement with said inner wall.
