Abstract

A threaded bolt for a hinge arrangement includes a cylindrical main body. On an outer circumferential surface thereof the cylindrical main body has a first frustoconical projection and a second frustoconical projection, which adjoins the first frustoconical projection. The diameter of a side of the first frustoconical projection that faces toward the second frustoconical projection is smaller than the diameter of a side of the second frustoconical projection that faces toward the first frustoconical projection. The first frustoconical projection comprises at least one tooth on its outer circumferential surface, which tooth protrudes radially beyond an imaginary continuation of the second frustoconical projection.

First claim

What is claimed is:

1. A threaded bolt for a hinge arrangement, comprising:
a cylindrical main body, wherein
on an outer circumferential surface thereof the cylindrical main body has a first frustoconical projection and a second frustoconical projection, which adjoins the first frustoconical projection,
the diameter of a side of the first frustoconical projection that faces toward the second frustoconical projection is smaller than the diameter of a side of the second frustoconical projection that faces toward the first frustoconical projection, and
the first frustoconical projection comprises at least one tooth on its outer circumferential surface, which at least one tooth protrudes radially beyond a continuation of the second frustoconical projection.

2. The threaded bolt according to claim 1 , wherein the cylindrical main body comprises a blind hole, in which a screw is screweable.

3. The threaded bolt according to claim 2 , wherein the at least one tooth is two teeth or three teeth.

4. A hinge arrangement, comprising:
a first hinge part with a through-bore and a frustoconical hinge eyelet, further comprising a threaded bolt according to claim 3 , wherein the at least one tooth is pressed in a wall defining the hinge eyelet of the first hinge part such that the second frustoconical projection rests against the wall and a cavity is formed between the first frustoconical projection and the wall.

5. The hinge arrangement according to claim 4 , further comprising a screw, which is screwed to the threaded bolt in the through-bore.

6. The hinge arrangement according to claim 5 , wherein the cavity is in the form of a frustoconical ring.

7. The hinge arrangement according to claim 6 , wherein an outer circumferential surface of the second frustoconical projection and the wall defining the hinge eyelet are devoid of unevennesses.

8. The hinge arrangement according to claim 7 , further comprising a second hinge part that is rotatably fixed to the threaded bolt.

9. The hinge arrangement according to claim 8 , wherein the first hinge part is fixed to a body of a motor vehicle or to a door of the motor vehicle.

10. The hinge arrangement according to claim 8 , wherein the second hinge part is fixed to a body of a motor vehicle.

11. The hinge arrangement according to claim 8 , wherein the first hinge part is fixed to a door of a motor vehicle.

12. The hinge arrangement according to claim 1 , wherein the second hinge part is fixed to a door of a motor vehicle.
