DE19517656C2 - Lifting and lowering device for furniture elements - Google Patents

Description

The invention relates to furniture elements that have lifting and guiding elements are firmly connected to a wall and which individually or together between an upper and a lower end position adjustable by means of a drive are.

Solutions are already known for lowering cupboard furniture allow. For example, according to the German patent DE 36 13 530 a cabinet furniture can be mounted on a vertical wall suggest that between an upper end position near the wall and a lower End position remote from the wall is adjustable parallel to the mounting wall. Invention according to at least one guide device on a base plate attached, which in turn consists of two guide elements, the one hand arranged on the base plate, on the other hand connected to the cabinet.

Modifications of the solution according to the invention use guide plates between which run guide profiles in the direction of movement of the cabinet. Another variant uses handlebar pairs as the guide device, their Handlebar arms are attached to the base plate and cabinet.

These solutions have in common that the guide device on the side Movable cabinet furniture is arranged and a side wall is required is firmly connected to the base plate.

Fluid-operated cylinders are used to raise and lower the cupboard furniture drives provided, each installed inside the cabinet furniture are.

The disadvantage of these solutions is that the movable closet space these measures is restricted. In addition, the proposed Solution disadvantageously the lateral attachment of the guide device, which too  considerable conversions or changes to the cabinet furniture.

The invention is therefore based on the object, optionally in its amount adjustable furniture elements that move individually or together develop that without lateral loss and loss of space in the for important, lower movable furniture elements, get along.

The movable furniture elements should also be from the usual series production come. They are therefore provided without conversions and installations and in all Usually offered variants can be used.

The movement devices are to be attached concealed to the optical Impression not to deteriorate compared to a conventional furniture element and should be sophisticated, maintenance-free and low-noise.

By easy assembly of the additionally required lifting and guiding furnishing is the greater effort compared to the usual furniture elements to reduce.

The object of the invention is achieved in that the furniture elements ( 2 ) can be adjusted individually or together between an upper end position near the wall and a lower end position remote from the wall by means of a drive ( 5 ) by means of a lifting and guiding device by which they are connected to a vertical wall are. ( Fig. 1, 2, 3)

The lifting device consists of a drive ( 5 ), the pivot points ( 4 ), ( 7 ), which are firmly connected to the base plate ( 1 ), the rotating elements ( 6 ) and ( 8 ), for connecting the coupling links (A) and ( B), a common fastening device ( 23 ) which is fixed to the pivot point ( 17 ).

The guide device consists of coupling links (C) and the pivot points ( 13 ), ( 18 ) and ( 22 ), which are connected to the base plate ( 1 ) and the pivot points ( 12 ), ( 19 ) and ( 21 ), which are connected to the fastening device ( 23 ) are connected.

The movable furniture elements ( 2 ) are optionally moved electrically, pneumatically or hydraulically by a drive ( 5 ) and can be switched via remote control switches in a manner known per se.

The lifting device is accommodated in a furniture element ( 3 ) fixed to the wall above the height-adjustable furniture element ( 2 ).

The drive ( 5 ) is fastened in point ( 4 ).

The drive is preferably equipped with a spindle thread. Of the For this purpose, the drive moves the spindle thread in such a way that in the drive direction the corresponding spindle is either moved up or down.

Via the fulcrum ( 7 ), which is firmly connected to the base plate ( 1 ), the force is transmitted via coupling elements (A) and (B) via the rotating element ( 8 ) and the fulcrum ( 17 ) to the fastening device ( 23 ). The coupling member (B) is firmly connected to the furniture element ( 2 ) via the pivot point ( 17 ) and the fastening device ( 23 ).

The guide device can optionally be designed such that the coupling elements (C) are arranged parallel to one another and are connected by means of a coupling element (D) via the rotating elements ( 20 ). ( Fig. 1)

On the other hand, there is the possibility of arranging a damping element (E) between the pivot point ( 24 ), which is firmly connected to the base plate ( 1 ), and the rotating element ( 20 ). The damping element (E) advantageously has a force-relieving effect.

Another embodiment of the guide device consists in that the coupling members (C) are arranged in a scissor-lattice configuration and are connected to one another via the rotary element ( 16 ) ( FIG. 3).

The base plate ( 1 ) in FIG. 2 can advantageously have a size that is uniform for all applications.

The base plate is connected to the lifting and guiding device. In order to lifting and guiding devices are possible that are economical sensible type prefabricated and optionally individually or in large numbers, but independently of each other, in a simple way on the mounting wall can be attached.

The lifting device is housed in the claimed form in a furniture element ( 3 ) which is fixed to the wall and which is above the height-adjustable furniture element ( 2 ). This arrangement ensures that only the fixed furniture element ( 3 ), which is difficult to reach for the user who is primarily addressed here (e.g. the disabled), is spatially loaded with the necessary lifting devices.

A special embodiment of the invention is made possible by the fastening device ( 23 ). Via the pivot points ( 12 ), ( 17 ) and ( 19 ) connected to it, the joint connection of lifting and guiding devices is achieved and at the same time the fastening and stable guidance of the movable furniture elements ( 2 ) is ensured. Modifications to the furniture elements weaving excluded, since the fastening device ( 23 ) is only attached to the rear of the furniture elements.

The invention is illustrated in the following exemplary embodiments explains:

Example 1: ( Fig. 1)

In the starting position, the movable furniture element ( 2 ) is located below the fixed furniture element ( 3 ). By retracting the drive, the coupling member (A) is moved about the pivot point ( 7 ) in such a way that the point ( 8 a) and the pivot point ( 17 a) are brought into position ( 8 b) or ( 17 b).

The furniture element ( 2 ) covers the path shown in Figure 1. The furniture element ( 2 ) is thus in the lower position away from the wall.

In order to ensure a parallel constraining guide of the furniture element (2), the coupling member (C) of the guide device which is fixed about pivot point (18) on the base plate (1), over the pivot points (19 a) from its starting position into the end position ( 19 b) performed.

The coupling links (C) thus give that for the furniture element guide necessary way.

Example 2: ( Fig. 3)

The movement of the furniture element ( 2 ) takes place initially via the drive ( 5 ), as in Example 1 ( Fig. 1).

The forced guidance of the furniture element ( 2 ) by means of the guiding device takes place like scissors.

The fixed pivot point ( 12 a) attached to the fastening device ( 23 ) is brought to ( 12 b). Thus the positively guided pivot points ( 13 ), ( 21 ) and ( 22 ) are guided along the guide profile ( 14 ) and ( 15 ). The guide profile ( 14 ) is attached to the base plate ( 1 ). The guide profile ( 15 ) is attached to the furniture element ( 2 ) on the back. The coupling elements (C) are rotatably connected to one another via the rotating element ( 16 ). This enables the scissor-like guidance of the coupling links.
