Abstract

Description of a bump stopper for a mobile part in the car body of a motor-vehicle, consisting of a fixed element (3) that can be secured into a seat of the car body an of a mobile element (25) that can be co-axially connected to the fixed element, and which can be translated along its axis, and locked in the desired position as a consequence of said rotation. The transversal section of said fixed element (3) is basically triangular and can be snapped into a hole seat made on the fixed element (15) of the car body. The section of the mobile element (25) is basically circular, the mobile element being provided with means (28) to Fit it on an upper element (17) of said fixed element external to the body of the motor-vehicle.

Claims

1. Plastic bump stopper for a mobile part of the body of a motor vehicle, consisting of a fixed element (3) that can be fixed into a seat of the car body and of a mobile element (25) that can be coaxially connected to the fixed element, and can be translated along its axis in order to separate it from the fixed element by means of a clockwise rotation, and that can be locked on a part (17) of said fixed element into the desired position, as a consequence of said rotation, through locking means (35, 37), characterised in that the fixed element (3) presents a basically triangular section and can be snapped into a hole seat the outline of which corresponds to that of the fixed element, made on a fixed part (15) of the car body and that the mobile element (25) presents a basically circular section and is provided with means (28) to fit it, in a predefined angular position, on an upper element (17) of said fixed element external to the car body.

2. Bump stopper as claimed in claim 1 characterised in that the fixed element (3) consists of a triangular base from the vertexes of which start three standards (6) which get wider in order to form a basically cone structure that reaches a circular diaphragm (7) the diameter of which is such that it protrudes from the external profile of said standards;

the upper face of said diaphragm being provided with a triangular body (17) at the vertexes of which there are rectangular lobes (18) that extend along the bisecting line of the corresponding angle, said triangular element having a diameter shorter than the diameter of the diaphragm (7).

3. Bump stopper as claimed in claim 1 and claim 2 characterised in that the standards (6), the base (4) and the diaphragm (7) define windows (10) from which protrude means intended for the fixing to the car body in the form of flexible teeth (12) provided of engaging notches (13).

4. Bump stopper as claimed in claim 2 characterised in that the diaphragm (7) presents a protuberance (9) as a reference for its angular position.

5. Bump stopper as claimed in claim 2 characterised in that one of the standards (6) presents a section which is different from those of the others which are identical among them.

6. Bump stopper as claimed in claim 2 characterised in that the upper triangular element (17) presents a horizontal indentation on its side walls.

7. Bump stopper as claimed in claim 2 characterised in that the upper triangular element (17) presents an axial hole the section of which is basically triangular (22), said hole presenting a slightly bent wall the concavity being towards the external part of the hole.

8. Bump stopper as claimed in claim 1 characterised in that the mobile element (25) is cup-lid shaped the external face of it being provided with a knurling (26) and with a triangular indicator for the angular position, a rubber cap (2) being fixed on the upper face of said lid.

9. Bump stopper as claimed in claim 1 characterised in that inside the cup-lid element (25) there is a mushroom-shaped element (26) the longitudinal section of which is basically T-shaped, the head of the T presenting a peripheral left-hand thread 30 adapted to become engaged with a corresponding thread made on the internal wall of the lid (25).

10. Bump stopper as claimed in claim 7 and claim 9 characterised in that the mushroom-shaped element (26) presents a coaxial stem the section of which is basically triangular, with a concave face and the outline and dimensions of which are such that it can be inserted in said axial hole (22) of the upper element (17).

11. Bump stopper as claimed in any of the previous claims characterised in that connected to the lower inner edge of the lid element (25) there is a ring (39) the internal outline of which is that of a truncated cone the diameter of which increases towards the inner part of the lid and which is adapted to co-operate with appendixes (35) connected to the head (29), placed basically parallel to the stem (28) and equally spaced along the inner circumference of the lid;

said appendixes presenting a truncated cone external outline with a diameter decreasing towards the edge of the lid and an inner outline basically as that of one of the side walls of the upper triangular element (17) and provided with horizontal knurling (37) adapted to get coupled with the knurling (20) of the triangular body (17) when pushed against it by the relative translation between the mobile element (25) and the mushroom-shaped element (26) as a consequence of the counterclockwise rotation of the mobile element (25).

12. Bump stopper as claimed in claim 11 characterised in that the ring 38 is fixed to the mobile lid element (25) by means of a thread made near the lower edge.

13. Bump stopper as claimed in claim 11 characterised in that the appendixes (35) are connected to the head (29) by means of thin film hinges.
