Abstract

The invention relates to an infinitely variable door arrester (1), especially for vehicle doors, that comprises the following components: a stationarily mountable first retainer (2), a second retainer (4) that is linked with the first retainer (2) so as to be movable with respect to the first retainer and that is linked with a door, mechanical stopping means (6) that block the two retainers (2, 4) within their range of movement in any relative position to each other in both directions of movement, elastic coupling means (14) that facilitate minimal, relative, elastic control movements in any relative position of the retainers (2, 4) blocked by the stopping means (6) by impinging the retainers with a control force, and control means (16) that control the release of the stopping means (6) in the blocked state by an elastic control movement resulting from the control force. The door arrester (1) is configured as a hinged door arrester, the two retainers (2, 4) being rotationally interlinked by a hinge pin (8) about a rotational axis (10).

Claims

1. An infinitely adjustable door arrester (1), in particular for vehicle doors, having the following components:

a first retaining part (2) which can be fastened in a fixed position,

a second retaining part (4) which is connected to the first retaining part (2) in a manner such that it can move relative to it and is to be connected to a door,

mechanical braking means (6) such that the two retaining parts (2, 4) can be blocked in any desired relative position with respect to each other within their range of movement in both directions of movement,

elastic coupling means (14) such that in each relative position of the retaining parts (2, 4) blocked by the braking means (6) small, relative, elastic control movements are possible by applying a control force, and

control means (16) such that in the respectively blocked state the braking means (6) can be activated for release purposes by means of an elastic control movement resulting from the control force,

characterized by a configuration of a hinge-type door holder, the two retaining parts (2, 4) being connected via a hinge pin (8) to each other in a manner such that they can rotate about a rotational axis (10).

2. The door arrester as claimed in claim 1, characterized in that the control means (16) are designed in such a manner that after release of the braking means (6) an immediately following, dynamic door movement keeps the braking means (6) in their release position, and in that, once at rest again, the braking means (6) automatically become blocked again by means of a force accumulator (18), in particular by spring force (F).

3. The door arrester as claimed in claim 1 or 2, characterized by an unhingeable design, the hinge pin (8) together with the braking means (6), the elastic coupling means (14) and the control means (16) being assigned to the one retaining part (2 or 4) and being connected via releasable connecting means (12) to the other retaining part (4 or 2) in a manner locked with respect to torque.

4. The door arrester as claimed in one of claims 1 to 3,

characterized in that the braking means (6) are designed in the manner of clamping tongs or a clamping chuck having tong-like braking elements (22), the braking elements (22), which interact with oblique active surfaces (26) for blocking purposes, preferably acting directly on the hinge pin (8).

5. The door arrester as claimed in one of claims 1 to 3,

characterized in that the braking means (6) are designed in the manner of a drum brake having jaw-like braking elements (34), the braking elements (34) being arranged within a drum-like housing part (36) and interacting with oblique active surfaces (38) of a tappet-like control part (40) for blocking purposes.

6. The door arrester as claimed in one of claims 1 to 5,

characterized in that the elastic coupling means (14) are formed by a section of the hinge pin (8) acting as a torsion spring and/or by elastomeric deformation elements (46) arranged between the retaining parts (2, 4).

7. The door arrester as claimed in one of claims 1 to 6,

characterized in that the control means (16) are formed by a slip coupling, which consists of two coupling parts (30, 32), in such a manner that, in the event of a relative movement caused by an elastic control movement, a control movement for release of the braking means (6) is also forced on the one coupling part (30).

8. The door arrester as claimed in one of claims 1 to 3,

characterized by a structural form which is rotationally asymmetrical with regard to the rotational axis (10) and, in particular, is approximately in the manner of a sector of a circle in cross section.

9. A door arrester as claimed in claim 8,

characterized in that the braking means (6) comprise a braking path (52) which is in the shape of a sector of a circle and has a concavely curved braking surface (52a), which is in the shape of an arc of a circle, and a braking element (54) which acts radially against the braking surface (52a) by means of spring force (F).

10. A door arrester as claimed in claim 9, characterized in that the braking path (52) is arranged in a housing (56) which is connected, preferably integrally, to the one retaining part (2 or 4), a guide part (58), which guides the braking element (54) and is connected in radial extent to the hinge pin (8) in a manner locked with respect to torque, being arranged within the housing (56) in a manner such that it can pivot relative to the braking path (52).

11. The door arrester as claimed in claim 10,

characterized in that the braking element (54) is guided in a guide holder of the guide part (58) with radial movement play and is subjected to the spring force (F) by the spring element (20).

12. The door arrester as claimed in claim 10 or 11,

characterized in that the elastic coupling means (14) are formed in the region of the braking path (52) by the braking path (52) being guided relative to the housing (56) in a manner such that it can move about the rotational axis (10) and being supported against the housing (56) in both directions of movement via elastic elements (60).

13. The door arrester as claimed in one of claims 9 to 12,

characterized in that the control means (16) have actuating means for releasing the braking element (54) counter to the spring force (F), the actuating means being, when an initially elastic relative movement between the retaining parts (2, 4) occurs, acted upon by resultantly acting driving means for the purpose of releasing the braking element (54).

14. The door arrester as claimed in claim 13,

characterized in that the actuating means are formed by a toggle lever element (66), two levers (68, 70), which are connected via a toggle joint (72), being arranged in the braked position stretched between the braking element (54) and an abutment—

formed, in particular, by a rotational joint section (74) of the hinge pin (8)—

in such a manner that deflection of the toggle joint (72) enables the braking element (54) to be pulled back into a release position.

15. The door arrester as claimed in claim 13 or 14,

characterized in that the driving means comprise a driving wheel (76) and a driving path (78) which is provided coaxially with respect to the braking path (52) and offset axially in the housing (56), the driving wheel (76), when rotated, deflecting, via a coupling (82), in particular a lip coupling, a drag lever (80) the end side of which acts, via a coupling element (84), on the toggle joint (72) of the toggle lever element (66).
