Claim:
A door handle type closure system consisting essentially of: a door handle movable from a vertical position to a horizontal position, the door handle having a coupling portion provided with at least one longitudinal rib; a movable latch attached to the coupling portion, which is movable by the handle for latching and unlatching a door; a bushing fixed to the door; and, a positioning washer made of a resilient thermoplastic material and having an annular body provided with two external upsets, two internal gaps located adjacent the two external upsets, the positioning washer having at least one cutout portion; each of said two resilient external upsets having a semicircular perimeter, the resilient external upsets being disposed at tangentially opposite positions on the washer; said two internal gaps being disposed as a mirror image thereto, each internal gap having a matching semicircular perimeter, said two internal gaps being deformable, whereby a diameter of the resilient positioning washer is temporarily modified; said at least one cutout portion providing a location for coupling with the at least one longitudinal rib of the door handle coupling portion such that the positioning washer moves therewith; said fixed bushing having a surrounding wall in an interior thereof, said surrounding wall having at least four entrances disposed in an equally-spaced manner therearound, said resilient positioning washer being rotatable within said fixed bushing such that the external upsets are alignable with said entrances; each said entrance having a semicircular perimeter sized to receive a perimeter of an external upset therein; said entrances being disposed about the fixed bushing, spaced in tangentially perpendicular positions relative to each other with a first pair of entrances corresponding to the vertical position of the door handle and a second pair of entrances corresponding to the horizontal position of said door handle; said entrances and said external upsets adapted to resiliently engage with sufficient force to limit movement of said door handle; and, wherein when said external upsets of the resilient positioning washer are resiliently received within said entrances, the door handle is held with sufficient force in said horizontal or vertical position to resist gravitational displacement of the door handle out of said horizontal or vertical position.
