| Description | A push type fastener for fastening a movable structural part to a fixed structural part, wherein the coupling and decoupling actions are both a push type operation, the fastener consisting of a plunger having a shank with a plunger head at one end and a threaded end portion at the other end, an expandable grommet adapted to receive the plunger shank there through, and an attachable head which is securable to the threaded end of the plunger shank. The fastener requires each structural part to be provided with an aperture and the attachable head to be smaller than the aperture in the second structural part. The plunger is extensible through the grommet and is structurally configured with an external camming surface which is cooperatively engageable with internal surfaces of the grommet so that when the plunger is inserted in the grommet, the relative positioning of said cooperable camming surfaces determines the expansion of the grommet. Coupling of the parts is effected when the grommet is inserted in the aperture in the fixed structural part and expanded by pushing the plunger head and plunger at least a minimal distance through the grommet. Decoupling is effected by pushing the attachable head. |
