Hinge

Abstract

Hinge with a hinge cup, which can be inserted into a boring in a furniture part, with a damper housing fixed onto the hinge cup, wherein the damper housing can be fastened onto or removably secured to the hinge cup wherein the damper housing is disposed at least partially outside the boring when the hinge cup is inserted into the boring in the furniture part.

Description

The invention concerns a hinge with a hinge cup which can be inserted into a boring in a furniture part, with a damper housing fixed onto the hinge cup.

Hinges fitted with a damper which brakes furniture doors during closing are known in the art from EP 1 199 433 A2, from the Austrian utility model AT 005 477 U1 and the German utility models DE 201 15 250 U and DE 202 05 905 U. The problem of the invention is to create a hinge with a damper such that the damper can be used universally.

The inventive problem is solved by the fact that the damper housing can be fastened onto or removably secured to the hinge cup wherein the damper housing is disposed at least partially outside the boring when the hinge cup is inserted into the boring in the furniture part.

Advantageously, provision is made for the damper housing to be disposed entirely outside the boring when the hinge cup is inserted into the boring in the furniture part.

A further embodiment of the invention makes provision that the hinge cup has a flange abutting on the furniture doors and that the damper housing is anchored on the flange of the hinge cup.

Next, one embodiment of the invention will be described with the aid of the figures in the attached drawings, which show:

In the embodiment shown, the damper 1 is anchored on the hinge cup 3 of a hinge 2. The hinge cup 3 is inserted in a boring in the furniture door 7 and linked via an articulated lever 5 with a hinge arm 4, which is anchored to a base plate 6. The base plate 6 is fixed to a side wall of the body of furniture 8, for example screwed into it.

The damper 1 is in the form of a rotation damper with a rotary piston 12. It comprises a two-part damper housing 9. In one housing part 10 a cylinder chamber 11 is formed, in which the rotary piston 12 of the damper 1 is disposed, and in the second housing part 13 there is a slider 14, which acts as the actuation element. The slider 14 is fitted with an insertion element 15 on which a toothed rack profile 16 is formed. The toothed rack profile 16 could also be formed directly on the slider 14. The insertion element 15 brings purely technical advantages.

The slider 14 runs displaceably in a recess 17 in the housing element 13 and is acted upon by a pressure spring 28. On the end of it which projects out of the damper housing 9, the slider 14 is equipped with a roller body 18, which rolls away along the hinge arm 4 when the furniture door 7 is closing.

The rotary piston 12 runs on an axis 19. At the other end of the axis 19 there is a pinion 20, which in the installation position is taken up into a recess 21 of the slider 14 and meshes with the toothed rack profile 16 of the insertion element 15.

The wing 22 of the rotary piston 12 has a valve which is formed by an opening 23 in the wing 22 and a leaf spring 24. If the rotary piston 12 is rotated in the direction of damping, the leaf spring 24 closes off the opening 23 in the wing 22, and the damping fluid is pressed through the gap between the tip 25 of the wing 22 and the wall 26 of the damper housing 9, as the result of which the desired damping effect is produced. When the furniture door 7 is opened the rotary piston 12 is rotated in the opposite direction, whereupon the leaf spring 24 opens and clears the opening 23, so that the damping fluid can also flow through he opening 23. The pressure spring 28 thereby slides the slider 14 back into the ready position.

The damper housing 9 or the housing element 10 respectively is equipped with a cover 27.

The hinge cup 3 has a flange 29 with an edge 30. In the edge 30 on opposite sides of the flange 29, recesses 31 are formed. The damper housing 9 of the rotary damper 1 has moulded elastic hooks 32 being part of the damper housing 9, which engage in the recesses 31 under the flange 29 when the rotary damper 1 is installed. The rotary damper 1 can thus be mounted without using tools onto the hinge cup 3, by simply pressing it onto the flange 29. Advantageously, the elastic hooks are designed so that the damper housing 9 is also detachable from the flange 29. The damper housing 9 can also be removed from the flange 29 without tools.

Since hinge arms 4 can have various forms, for example there are also cranked hinge arms 4, the invention makes provision for an attachment 17 to be attachable to the hinge arm 4, on which the control surface 21 for the actuation element in the embodiment of the slider 14 is formed. When the door 7 is closing the actuation element presses with its free end on the control surface 21. The control surface 21 describes a curved path, which is adapted to the respective requirements. The control surface 21 can be inclined in opposing directions, and be concave, convex or also straight and angled in form. This allows a specific influencing of the closing characteristics of different hinge types and different closure mechanisms.

The attachment is equipped, for example, with lugs 33 and the hinge arm 4 with holes 34, so that if necessary the attachment 17 can easily be pressed onto the hinge arm 4.
