Opening and/or closing device for furniture

The present invention relates to an opening and/or closing device for furniture, in order to accelerate, brake and/or hold a movable furniture part relative to a furniture body, with a mounting element that can be fixed to the movable furniture part or furniture body and to which an activator can be attached via a Adjusting mechanism is held, wherein the activator can be coupled to a mechanism for accelerating, braking and / or holding and is adjustable relative to the mounting element via a first actuating element in a first direction.

EP 2 266 436 B1 discloses an opening and/or closing device for a sliding element which can be locked in a closed position via a locking mechanism. A locking bar is provided for this purpose, on which a locking mechanism is provided so that only one of the sliding elements arranged one above the other can be pulled out of the furniture body. For this purpose, each sliding element has an activator that can be coupled to the locking mechanism. Alignment of the activator to the locking mechanism is necessary for error-free, smooth-running function. The locking mechanism includes an adjusting element to adjust a depth position, so that the position of a front panel can be adjusted relative to the furniture body. A further adjustment option is not provided.

AT 14959 U1 discloses a drawer lock for locking drawers when one of the drawers has been moved to an open position. A catching part is provided on the locking device and is arranged on an adjustment mechanism in order to align the catching part during assembly. The assembly is therefore comparatively complex and requires the respective catch part to be aligned during assembly. Although the catching part is attached to the panel in a pivotable manner, it cannot be displaced for an adjustment process.

It is therefore the object of the present invention to create an opening and/or closing device for furniture which enables flexible alignment of an activator which can be coupled to a mechanism for accelerating, braking and/or holding.

This object is achieved with an opening and/or closing device having the features of claim 1.

In the opening and/or closing device according to the invention, the activator is connected to a mounting element via an adjusting mechanism, the activator being adjustable in a first direction relative to the mounting element via a first adjusting element, and the adjusting mechanism comprising an activator carrier on which a second adjusting element for Adjusting the activator is provided relative to the mounting element in a second direction at an angle to the first direction. As a result, the activator can be adjusted in two different directions relative to the assembly element via the at least two adjusting elements, which makes it easier to align the activator and can compensate for assembly tolerances when assembling the piece of furniture.

Preferably, a housing is adjustably held on the mounting element, on which a third adjusting element is provided for adjusting the activator relative to the mounting element in a third direction at an angle to the first and the second direction. As a result, the activator can be adjusted in three different directions relative to the mounting element, so that the activator can be adjusted in depth, height and sideways. The three adjusting elements can adjust the activator in three directions, each of which is aligned perpendicular to one another.

In a preferred embodiment, the activator is fixed to a bar or formed integrally with it, which is held displaceably on the activator carrier. The strip can be aligned in the longitudinal direction perpendicular to an axial direction of a pin or projection that can be coupled to a driver. The activator can be held and guided stably on the activator carrier via the bar.

The activator carrier preferably has a receptacle for guiding the strip with the activator, and the activator carrier is guided in a displaceable manner along the housing. The housing in turn can be slidably held on the mounting element, so that the slidable arrangement of the housing on the mounting element, the activator on the housing and the activator on the activator support an adjustment in three different

15

35

Directions is made possible, with the activator carrier being held comparatively stable on the mounting element after the adjustment.

For a stable fixation of the mounting element, this can be designed as a mounting plate, which is fixed, for example, by means of fasteners on the movable furniture part or the furniture body and on which guide means, for example guide rails, are provided for adjustable fixing of the housing. The housing can at least partially enclose the mounting element with angled guide rails.

For a simple adjusting mechanism, the first, second and/or third adjusting element can be pivoted. For this purpose, each of the adjusting elements can optionally be designed as an eccentric or worm wheel drive. At least one adjusting element, preferably all adjusting elements, can be latched in the adjusted adjusting position for secure fixing of the respectively adjusted position.

For a particularly compact design of the adjustment mechanism, three receptacles can be formed on the housing, in each of which an actuating element engages and is rotatably mounted. As a result, the activator can be positioned on the housing using the three adjustment elements.

In a piece of furniture, a plurality of sliding elements arranged one above the other, such as drawers, movable shelves, containers, suspension file frames or other devices, are preferably arranged on a furniture body, which are each coupled to an opening and/or closing device in a closed position. A locking mechanism can be fixed to the furniture body, which locks the other sliding elements in a closed position when one sliding element is opened. Assembly is made easier if an activator is fixed to each sliding element, preferably to the rear of a front panel, via a mounting element. However, the opening and/or closing device can also be used in other mechanisms, for example in retraction devices, ejection devices or damping devices. In addition, the opening and/or closing device can be used not only with sliding elements but also with sliding doors.

The invention is explained in more detail below using an exemplary embodiment with reference to the accompanying drawings. Show it:
