Door handle type closure system discloses an exclusive "positioning washer" that helps to keep the positioning of the door handle when in "open" or "closed" position, as well as it transfers the sensation of limit, wherein said "positioning washer" is made of thermoplastic material and has characteristics of resilience (spring effect), and thus it is able to define the "limit" of the door handle, both to open and to close the system; said "limit", which is resultant of the physical constructiveness of said positioning washer and said fixed bushing, eliminates the gravity effect on the clearances among the components of the closure system disclosed herein, and, consequently, the positioning of the door handle is kept, since its "misalignment" is eliminated; the door handle (1) is attached to the closure system, wherein its longitudinal ribs (1.2) are housed into said cuts (2.3) of the washer (2); in the "open position", the washer (2) is housed into said fixed bushing (3) so that its external upsets (2.1) are arranged within two entrances (3.2) located in opposite to said fixed bushing (3); in the "intermediate position", said external upsets (2.1) of the washer (2) are dislocated from said entrances (3.2) of the fixed bushing (3), wherein part of said washer (2) is deformed, so as to reduce the original diameter of said washer (2); in the "closed position", said washer (2) is housed into said fixed bushing (3) so that its external upsets (2.1) are arranged within two entrances (3.2) located in opposite to said fixed bushing (3). |
