Description

DESCRIPTION

Furniture hinge

The present invention relates to a furniture hinge with the features of the preamble of claim 1.

Document DE 20115250 shows a damping device for a furniture hinge, which is placed on the hinge part. In this regard, a piston rod is pressed into a shock absorber housing during a movement of the hinge part and is moved back to the extended position during an opening movement. Such a furniture hinge comparatively needs a lot of construction space and has a complex structure.

From EP 1555372 a furniture hinge is known in which a hinge part is pivotably placed on a side part. For this purpose, a support lever and a guide lever are provided, which pivot the fixed hinge piece in a movable part in a movable furniture part, such as a furniture door. To dampen the movement, a linear shock absorber is provided on the side, which is connected to a shoulder on the guide lever through a chain link. Therefore, damping is performed during a pivoting of the guide lever. In this respect, the coupling is rigidly configured, so that a limited tolerance compensation is possible, in particular when a furniture door is aligned and, in this respect, the hinge part is adjusted relatively to the side part or a mounting plate In addition, the coupling through the chain links is comparatively complex and more difficult to assemble. A similar hinge is also shown in EP 1375797 A1.

In WO 2006/053364 A1 a hinge with at least seven rotating axes is disclosed, which is configured as a high-angle hinge and in which a linear damper is fitted on the outside in an intermediate piece of the hinge.

WO 2006/042344 A1 discloses a damper arrangement on a hinge, which has a push rod under pressure, which can be supported on an adjustable support element.

In document US2003 / 0200625 a damper arrangement is shown on a hinge, in which a linear shock absorber is arranged on a pivotable hinge part which can be operated through a pushrod with a sliding surface. The sliding surface establishes contact through a hinge lever.

EP1375797 discloses the features of the preamble of claim 1.

Therefore, the objective of the present invention is to create a furniture hinge that allows, with a simple structure, a damping of the movement of the hinge part.

This objective is solved with a furniture hinge with the characteristics of claim 1.

According to the invention, a contact surface is arranged on the support lever or the guide lever, acting for damping by a closing movement of the hinge part directly on the shock absorber housing or the piston rod. With this, with a minimum number of components, both the function of the furniture hinge with a damping of the closing movement can be achieved. In addition, this structure is comparatively easy to assemble, since the piston rod or shock absorber housing does not attach to a connecting element coupled to the hinge part. Rather, the timing of the damping is caused by touching the contact surface on the shock absorber housing or the piston rod, the initial damping point can also be designed in an adjustable manner.

According to a preferred configuration of the invention, the contact surface is configured in an integrated manner with the support lever or the guide lever. Then a protrusion, which forms the contact surface, can be configured in an integrated manner. Preferably, this shoulder is configured on the support lever.

The contact surface preferably touches one end of the piston rod where the shock absorber is simply fixed to the housing on a side part or the mounting plate. In this regard, the piston rod can slide over the contact surface also in a certain frame to compensate for a movement towards the sides of the contact surface.

In accordance with the invention, damping is not achieved throughout the pivoting path of the hinge part, but the contact surface touches the piston rod or the damper housing only when the hinge part is disposed between a position of closing and an opening angle of 10 ° to 40 °, preferably 15 ° to 30 °. Generally, in the area of an opening position a damping has to be performed, since This only makes handling difficult. Avoid slamming the door only before closing the furniture door. Therefore, it is sufficient when the shock absorber is only effective in an end area before the closing position. In this regard, the shock absorber is prestressed through a spring in the extended position, so that, in the case of an opening of the hinge part, the shock absorber automatically moves to the extended position. The shock absorber housing is fixed to the side or mounting plate. The housing can also be adjustable in the longitudinal direction of the hinge part so that the damping point can then be adjusted. The invention is explained in more detail below by an exemplary embodiment with reference to the attached drawings. They show:

Figure 1, a partially sectioned side view of an embodiment of a furniture hinge according to the invention in the open position;

Figure 2, a view of the furniture hinge of Figure 1 in a slightly open position only, and Figure 3, a view of the furniture hinge of Figure 1 in the closed position.

A metal or plastic furniture hinge 1 comprises a mounting plate 2 that can be fixed to a furniture body, on which a side part 3 is fixedly or adjustablely arranged. On the side part 3 a pivotally placed a hinge part 4 cup-shaped. The hinge part 4 may be inserted in a recess of a furniture door for pivotable placement.

For this, the hinge part 4 is connected to the side part through a support lever 5 and a guide lever 6, the support lever 5 being attached to the side part through an axis 8 and through a axis 7 to the hinge part 4, and the guide lever 6 being connected through an axis 9 to the hinge part 4 and through an axis 10 to the side part 3.

To dampen the pivoting movement of the hinge part 4, a damper with a damper housing 13 and a piston rod 12 of linear movement is provided. The damper can be configured as a fluid buffer or as a pressurized gas damper. A spring 14 is provided in the housing of the shock absorber 13, which presses the piston rod 12 towards the extended position. One end of the piston rod 12 may rest on a contact surface 15, which is provided on a shoulder 11 that is formed in an integrated manner with the support lever 5.

In figure 1 the hinge part 4 is shown in a fully open position. The piston rod 12 is in the extended position because of the force of the spring 14.

In Figure 2, the hinge part 4 has been pivoted to a position only slightly open, which has approximately an opening angle of about 45 °. In this position, the shoulder 11 with the contact surface 15 is disposed distantly from the end of the piston rod 12, so that the shock absorber is not yet effective.

Figure 3 shows the closed position of the furniture hinge 1. During pivoting the hinge part 4, the contact surface 15 presses briefly before the closed position, approximately in a range between 10 ° and 40 °, preferably from 20 ° to 30 °, against the end of the piston rod 12, so that it moves towards the housing of the damper 13. In this way, the closing movement of the hinge part 4 is damped. In this respect, the hinge part 4 is prestressed by a spring to the closed position, the force of this spring being greater than the force of the spring 14 in the damper housing 13.

In the exemplary embodiment shown, the tip of the piston rod 12 rests directly on the contact surface 15. Naturally, it is possible to provide a sliding element on the piston rod 12. Apart from that, the contact surface 15 can also act on the shock absorber housing 13, then the piston rod 12 is supported on the side 3 or the mounting plate 2.
