Description

The The present invention relates to an adjusting device for Furniture, with a housing and a sliding on it mounted part in which a recess and a rotary member arranged is that when rotating the surrounding housing relative to the Part moves.

There are different adjustment devices for furniture. From the DE 77 19 324 a drawer is known in which a base plate is fixed to a side plate with an eccentric disc. The rotatably mounted eccentric can act on an elbow, which is fixed to the front panel. Thereby, the position of the front panel can be changed relative to the side wall, in particular to align the front panel to a front of a piece of furniture. Such an adjustment is comparatively expensive to install, since the base plate and the elbow must be fixed to the side wall or front panel and then a corresponding adjustment must be made to align. An eccentric adjustment has the disadvantage that the adjustment path changes strongly and non-linearly relative to the angle of rotation, which leads to an uneven adjustment with uniform rotation. In addition, the effective lever arm changes and the maximum displacement is limited.

It Therefore, an object of the present invention is an adjustment to create furniture that is simple in construction easy to install and allows exact adjustment.

These Task is with an adjustment device for furniture solved with the features of claim 1.

According to the invention the rotary element on two control discs, each on a contact surface act on the recess. Here are the contact surfaces in the direction of adjustment on opposite sides of the Recess arranged so that the maximum adjustment is very large, because a control disc is responsible for moving only in one direction is. Each control disc only acts on one contact surface at the recess and at the opposite side the respective control disc spaced from a side wall arranged the recess.

According to one preferred embodiment of the adjusting device are the control discs designed so that the angle of rotation and the sliding path substantially over the entire displacement are proportional. Unlike one Eccentric allows the geometry of the control disc so choose that a change in angle when twisting the rotating element provides for a proportional displacement Preferably, the rotary member for moving the housing over a rotation angle of more than 180 °, preferably more than 210 °, rotatable. There are also rotational angles of more than 240 ° feasible, for example, up to almost 360 °, so a big one Angular range can be used for the sliding movement can.

Further it is advantageous if in the adjusting the rotary member has an axis of rotation, wherein the effective lever arm for adjusting of the housing is substantially constant. The control discs can each have an outer contact surface in the form of an involute, which extends around a base circle. As a result, the effective lever arm is kept constant, so that the forces stay the same when adjusting. The two control discs can in a basic position to a middle Level perpendicular to the adjustment be symmetrical. Preferably, the recess for a compact design arranged on the displaceably mounted part. Then the rotary element is over at least one pin rotatably mounted on the housing. In addition, the housing can be a receptacle for insertion have an end portion of the displaceably mounted part, so that the end portion is not visible from the outside.

According to one Alternative embodiment of the invention is the recess on the Housing formed and the rotary member is over rotatable at least one pin on the displaceably mounted part stored, so that in the part only a circular opening must be provided as a bearing bush.

The Adjustment device can be formed for example as a multi-part rail be adjustable to adjust the inclination of the front panel in length is and at least two slidably led together Parts has. This may affect the adjustment of the front panel done in a simple manner in which only the length of the railing is adjusted accordingly. This is especially possible to use in drawers where the change in length the railing to another position of the front panel in the upper area spaced from a floor leads. The adjusting device is then simple with just a few components. In addition, can the adjusting device also for other furniture fittings, For example, hinges, mounting plates, sliding elements be used for sliding doors o. Ä.

According to a further embodiment, the housing surrounds a rod-shaped part which is slidably received in the housing. This allows a stable linear guidance in adjustment direction, with a support in different directions is given perpendicular to the adjustment.
