Abstract:
1. A shock dampener bumper for motor-vehicles, adapted to be applied on motor-vehicles of various kind, both for personal uses and for sports contests, in order to protect the constructive structure of the motor-vehicle from possible damage and/or breakage thereof in the case in which the motor-vehicle falls, comprising first and second component parts combined and assembled to each other with adequate arrangements, of which said first component parts are made of semi-rigid materials selected from the group consisting of magnesium, plastic, aluminium and other metallic and/or plastic materials having similar characteristics, which are adapted to be secured to and supported by the motor-vehicle constructive structure and to come into contact with the ground when the motor-vehicle falls, said first component parts including a first shaped disc ( 8 ), turned towards the motor-vehicle constructive structure for being secured to and supported by the same by fixing means ( 20 ), a support bush ( 10 ) and a covering cap ( 11 ), turned outwards and adapted to come into contact with the ground during the fall, said first disc ( 8 ) being shaped with a flat back surface ( 12 ) turned towards the motor-vehicle and joined to a short central hub ( 13 ), also turned towards the motor-vehicle and projected towards the motor vehicle beyond said back surface ( 12 ), said first disc ( 8 ) also shaped with a flat front surface ( 14 ) turned in an opposite direction, which is joined at one end portion thereof to a central collar ( 15 ) slightly projected outwards, and at the other end portion thereof to a flat inclined circular shaped peripheral edge ( 17 ), said first disc ( 8 ) being further provided with an axial and central through hole ( 19 ) provided through said hub ( 13 ) and said collar ( 15 ), for the insertion and the fixing of said fixing means ( 20 ), and said second component parts being made of an elastomeric material and being interposed between said first component parts, in order to dampen and absorb the energy of the shocks and related vibrations, which are produced during the fall, said second component parts including a second shaped disc ( 9 ), adaptable between said first disc ( 8 ) and said covering cap ( 11 ) and couplable with the same by means of said bush ( 10 ) and said fixing means ( 20 ), wherein said second disc ( 9 ) is shaped with a projected back surface ( 24 ) having an outline adaptable by insertion with the flat front surface ( 14 ) of said first disc ( 8 ), and joined with its outer end portion with a flat inclined circular shaped peripheral edge ( 25 ) and with its inner end portion with an axial and central through hole ( 26 ), provided in a position coinciding to that of the central through hole ( 19 ) of said first disc ( 8 ), said second disc ( 9 ) being also shaped with a flat front surface ( 27 ) turned in an opposite direction, which is joined at its one end portion with a flat and cylindrical central collar ( 28 ) , which is depressed with respect to said front surface ( 27 ) and delimits said central through hole ( 26 ), and at its other end portion is joined to said flat inclined peripheral edge ( 25 ).
