Abstract

The invention relates to a hinge comprising a moveable hinge section and a hinge section consisting of a fixed stop section, which are interconnected by at least one joint axis, and comprising a damping device mounted on one of the hinge sections whose translationally or rotatably moveable damping member is acted upon at least in the closure region of the hinge via gear means from the other hinge section. According to the invention for adjustment of the moveable damping member depending on the tilt of the moveable hinge section relative to the at least one joint axis, there is provided at least three moveable gear members are provided, of which one is the damping member itself.

Claims

1. A hinge (1), comprising

a first movable hinge section (3),

a second hinge section (2) including a fixed stop section,

at least one joint axis interconnecting said first and second hinge sections (3, 2),

a damping device mounted upon one of said first and second hinge sections (3, 2) and comprising at least one damping member (16) mounted for rotational movement,

gear means mounted for acting upon said at least one damping member (16) at least in a region of a closed position of said hinge (1),

said gear means comprising at least three movable gear members (20, 22, 45),

an axis (61) positioned upon one of said hinge sections (2, 3) for supporting one of said gear members (22) intermediately-mounted between said two other gear members (20, 45) of said at least three gear members (20, 22, 45),

said intermediately-mounted gear member (22) comprising two separate engaging members (21, 23) arranged

(i) concentrically about said axis (61) supporting said intermediately-mounted gear member (22),

(ii) at a periphery of said intermediately-mounted gear member (22), and

(iii) at unequal distance from said axis (61) supporting said intermediately-mounted gear (22),

with one of said engaging members (23) mounted further from said axis (61) arranged to engage one (20) of said gears (20, 22, 45) contacting said damping member (16),

said other engaging member (21) mounted closer to said axis (61) arranged to engage the other (45) of said gears (20, 22, 45), and

said other (45) of said gear members (20, 22,45) being rotatably mounted upon an axis (60) situated upon said hinge section (2) on which said damping device (16) is mounted and arranged to engage both said intermediately-positioned gear (22) and other hinge section (3).

2. The hinge of claim 1, wherein said engaging members (21, 23) are constituted by toothed segments (21, 23) concentrically-curved with respect to said axis (61) upon which said intermediately-positioned gear (22) is mounted and having different radii of curvature,

with one of said engaging members (23) mounted further from said axis (61) having the larger radius of curvature and said other engaging member (21) mounted closer to said axis (61) having the smaller radius of curvature, and

said other (45) of said gears (20, 22, 45) being rotatably mounted and comprising a toothed segment (48) arranged to engage said toothed segment (21) having the smaller radius of curvature.

3. The hinge of claim 2 wherein ratio of said smaller:

larger radii is from 1;

1.5 to 1;

3.

4. The hinge of claim 1, wherein

said damping member (16), and other (45) of said gears (20, 22, 23) are both rotatably mounted upon said fixed hinge section (2).

5. The hinge of claim 1, wherein said other (45) of said gear members (20, 22, 45) comprises a projection (46) arranged to project into a swivel path of said movable hinge section (3) in open position of said hinge (1) and be actuated by said movable hinge section (3) upon closing of said hinge (1).

6. The hinge of claim 5, additionally comprising

a spring (58) arranged to pre-stress said damping device (16) in the open position of said hinge (1) and act upon at least one of said intermediately-positioned and other gear members (22, 45).

7. The hinge of claim 6, wherein said projection (46) is constituted by a lever arm (46) extending radially away from the axis of rotation (60) thereof and projecting through an opening (44) of a cup-shaped recess of the fixed hinge section (2) on which said other gear (45) is mounted,

such that the lever arm (46) lies in a swivel path of the movable hinge section (3) which actuates said other gear member (45) upon closing.

8. The hinge of claim 1, wherein one (2) of said hinge sections (2,3) to which at least one of said damping device (16) and gear members (22, 45) are affixed, is constructed as a hinge cup having a flange.

9. The hinge of claim 1, wherein at least one of said damping device (16) and three gear members (20, 22, 45) comprises a pivoting axis (62, 61, 60) extending substantially normal to said joint axis.

10. The hinge of claim 1, wherein

said damping device comprises a plurality of damping members (16, 16), and

said engaging member (23) mounted further from said axis (61) of said intermediately-positioned gear member (22) is arranged to actuate all said damping members (16), in common.

11. The hinge of claim 1, wherein said intermediately-mounted gear (22) and other gear member (45) are arranged to engage at an angular position 20°

-30°

before reaching a completely-closed position of said hinge (1) to provide damping action.

12. The hinge of claim 1, wherein a gear (20) of said three gears (20, 22, 45) contacting said damping member (16) is a pinion keyed onto said damping member (16).

13. The hinge of claim 12, wherein

said damping device comprises two rotation dampers (16) mounted upon respective axes of rotation (62), and

said gear means comprise two pinions (20) each being mounted upon the respective axis of rotation (62) of the rotation damper (16) and meshing with the engaging member (23) of said intermediately-positioned gear mounted further from the axis of rotation (61) thereof.

14. The hinge of claim 1, wherein said other gear (45) additionally comprises a lever arm (46) extending radially away from the axis of rotation (60) thereof and projecting through an opening (44) of a cup-shaped recess of the hinge section (2) on which said other gear (45) is mounted,

such that the lever arm (46) lies in a swivel path of the movable hinge section (3) which actuates said other gear member (45) upon closing.
