Description

A furniture hinge The present invention relates to a furniture hinge, comprising a mounting plate on which a side part is arranged, and a hinge part mounted pivotably on the side part via a support lever and a guide lever, with a damper being provided to dampen the movement of the hinge part relative to the side part. DE 20115250 shows a damping apparatus for a furniture hinge which is placed on the hinge part. The piston rod is pressed into a damper housing during a movement of the hinge part and moved to the extended position again during an opening movement. Such a furniture hinge requires a comparatively large amount of overall space and has a complex arrangement. A furniture hinge is known from EP 1555372, in which a hinge part is pivotably held on a side part. For this purpose, a support lever and a guide lever are provided which in the manner of a parallel control arm pivot the hinge part fastened to a movable furniture part such as a furniture door. For damping the movement, a linear damper is provided on the side part which is coupled via a chain link with a projection on the guide lever. Damping thus occurs during the pivoting of the guide lever. The coupling is provided with a rigid configuration, so that a limited compensation for tolerances is possible, especially when a furniture door is aligned and the hinge part is adjusted thereby relative to the side part or a mounting plate. Moreover, the coupling via chain links is relatively complex and difficult to mount. It is therefore the object of the present invention to provide a furniture hinge which enables a damping of the movement of the hinge part in combination with simple arrangement. This object is achieved with a furniture hinge with the features of claim 1. In accordance with the invention, a contact surface is arranged on the hinge part, the support lever or the guide lever, with forces acting directly on the damper housing or the piston rod for damping during a closing movement of the hinge part. Both the function of the furniture hinge with a damping of the closing movement can thus be achieved with a minimum number of components. Moreover, this arrangement is comparatively easy to mount because the piston rod or the damper housing are not connected with a connecting element coupled with the hinge part. Rather, the time of damping is effected by the touching the contact surface on the damper housing or piston rod, with the initial point of damping also being provided with an adjustable configuration. In accordance with a preferred embodiment of the invention, the contact surface is provided to be integrally arranged with the hinge part, the support lever or the guide lever. A projection can then be integrally provided which forms the contact surface. Preferably, this projection is arranged on the support lever. The contact surface preferably touches one end of the piston rod where the damper can be fixed with the housing in a simple manner to the side part or the mounting plate. The piston rod can also slide on the contact surface in a certain frame in order to compensate any lateral movement of the contact surface. According to a further embodiment of the invention, damping is not achieved over the entire pivoting path of the hinge part, but the contact surface touches the piston rod or damper housing only when the hinge part is arranged between a closed position and an opening angle of 100 to 400, preferably 150 to 300. Damping must mostly occur in the region of an opened position because this would adversely affect handling. Slamming should be prevented merely before the closing of the furniture door. That is why it is sufficient when the damper is effective only in an end region before the closed position. Preferably, damper is pretensioned via a spring to the extended position, so that when the hinge part is opened the damper will automatically be moved to the extended position. The housing of the damper is preferably fixed to the side part or mounting plate. The housing can then also be adjustable in the longitudinal direction of the hinge part in order to then enable the setting of damping points. The invention is now explained in closer detail by reference to an embodiment shown in the enclosed drawings, wherein: Fig. I shows a partly sectional side view of a furniture hinge in accordance with the invention in the opened position; Fig. 2 shows a view of the furniture hinge of Fig. I in an only slightly opened position, and Fig. 3 shows a view of the furniture hinge of Fig. 1 in the closed position. A furniture hinge 1 made of metal or plastic comprises a mounting plate 2 which can be fixed to a furniture carcass and on which a side part 3 is arranged in a fixed or adjustable way. A pot-like hinge part 4 is pivotably held on the side part 3. The hinge part 4 can be inserted into a recess of a furniture door for holding it in a pivoting manner. For this purpose, the hinge part 4 is connected to the side part via a support lever 5 and a guide lever 6, with the support lever 5 being connected with the side part via an axis 8 and with the hinge part 4 via an axis 7, and the guide lever 6 is connected via an axis 9 with the hinge part 4 and via an axis 10 with the side part 3. In order to dampen the pivoting movement of the hinge part 4, a damper is provided which comprises a damper housing 13 and a linearly movable piston rod 12. The damper can be arranged as a fluid damper or as a gas-pressure damper. A spring 14 is provided on the damper housing 13 which presses the piston rod 12 to the extended position. One end of the piston rod 12 can rest on a contact surface 15 which is provided on a projection 11 which is formed integrally with the support lever 5. Fig. 1 shows the hinge part 4 in a widely opened position. The piston rod 12 is located in the extended position due to the force of the spring 14. In Fig. 2, the hinge part 4 was pivoted to an only slightly opened position which has an opening angle ax of approximately 45*. In this position, the projection 11 with the contact surface 15 is spaced from the end of the piston rod 12, so that the damper is not yet effective. Fig. 3 shows the closed position of the furniture hinge 1. When the hinge part 4 is pivoted, the contact surface 15 presses against the end of the piston rod 12 shortly before the closed position, approximately in a range of between 100 to 400, preferably 200 to 300, so that the same is moved into the damper housing 13. The closing movement of the hinge part 4 is thus dampened. The hinge part 4 is pretensioned by a spring to the closed position, with the force of said spring being larger than the force of spring 14 in the damper housing 13.

In the illustrated embodiment, the tip of the piston rod 12 rests directly on the contact surface 15. It is obviously possible to provide the piston rod 12 with a sliding element. Furthermore, the contact surface 15 can also act upon the damper housing 13. In this case, the piston rod 12 is supported on the side part 3 or the mounting plate 2.
