Abstract
A door handle closure system has a positioning washer that holds a door handle in an “open” or “closed” position. The positioning washer is made of a resilient thermoplastic material, providing a positive spring feeling when the door handle reaches the opened or closed positions. The door handle (1) has a longitudinal rib (1.2) received in a cut (2.3) provided in the washer (2). In the open position, the washer (2) has external upsets which are received within two entrances (3.2) located in the fixed bushing (3). In any intermediate position, the external upsets (2.1) are dislocated from the entrances (3.2) of the fixed bushing (3), deforming part of the washer (2), so as to reduce its original diameter, in effect, loading the “spring”. In the closed position, the external upsets (2.1) are received within two entrances (3.2) located opposite thereto in the fixed bushing (3), relieving the spring pressure.
