description

The invention relates to an adjusting device for adjusting, in particular for moving and / or opening and closing at least one drawer, a flap, a door or the like, which in a piece of furniture, such as a cabinet, especially a kitchen cabinet, or in a vehicle such For example, a commercial vehicle, in particular a service or emergency vehicle can be arranged, with at least one electric motor drive unit, which acts on a transmission means for adjusting the at least one drawer, a flap, a door or the like.

State of the art

Such adjusting is known for example from DE 91 13 223 Ul. As a transfer agent is used a friction wheel whose axis of rotation is perpendicular to the extension direction of the drawer and is arranged in the region below the respective drawer. The drawer has on its underside, or its bottom, a strip or the like, on which the friction wheel rests frictionally. Depending on the direction of rotation of the electric motor drive unit and thus the friction wheel, the drawer is extended or retracted. problem

In this known from the prior art adjusting device for moving a drawer occurs an excessively high wear of the friction wheel, so that it comes to malfunction of the adjustment. Such malfunctions occur when the friction wheel no longer exerts sufficient friction on the arranged on the bottom or the bottom of the drawer strip. The lack of frictional engagement then causes the drawer can not be properly opened or closed.

Furthermore, from DE 11 44 892 A a desk known. This has a lower box with drawers and arranged in the table top selection buttons for forward and backward drawer slide. A motor drives via a shaft and a sprocket to a chain, which puts a drive sprocket in revolutions via another sprocket and another shaft. The drive gear engages in a rack attached to the underside of a drawer, whereby the drawers can be moved in the open and closed positions.

In this prior art, the many individual parts of the device prove to be disadvantageous, as this makes the entire device is very prone to failure. task

This object is achieved by a device having the features of claim 1. Advantageous embodiments of the invention can be found in the subclaims.

Due to the fact that a transmission means arranged so as to be displaceable in a guide is provided on which the drive unit acts, only negligible signs of wear occur as a result of friction, so that the movement of the furniture part over its entire service life is ensured. The susceptibility to interference is minimized to a considerable extent, since the items necessary for adjusting are considerably reduced compared to the prior art.

According to a first advantageous embodiment of the invention, a pitch cable is used as the transmission means. In addition to the negligible wear, such pitch cables have the advantage that they do not place any great demands on the space required for arrangement on the furniture or the furniture part, since they are very small in construction. In addition, due to the flexibility of the transmission means of Advantage that they can be mounted in different arrangements on the furniture or the vehicle.

Advantageously, the drive unit has a pinion, which engages in the pitch cable and thus converts the rotational movement of a drive shaft of the drive in a translational movement of the pitch cable. This makes it possible that an adjustment, in particular a displacement, for example, to open and close the at least one drawer, a flap, a door or the like is possible.

Alternatively, it is also possible that a train-pressure cable is provided as a transmission means. Also, such train-pressure cable can be used in a simple manner by a drive for adjusting the at least one drawer, a door, a flap or the like. The simplest example of this may be arranged on the drive-side end of the train-pressure cable, a rack which can also be translated by a mounted on a drive shaft of the drive pinion and thus their movement to the train pressure cable and thus the at least a drawer, flap, door or the like transfers.

It has also proved to be advantageous that the drive is self-locking. By this measure, it is possible that the furniture part is not manually displaceable in the normal operating state of the adjustment. Thus, an effective anti-theft protection for stored in the drawer or behind the flap or door of the furniture or the vehicle items is given, since an adjustment is possible only by the electromotive actuation adjustment.

According to a further advantageous embodiment of the invention, the transmission means is arranged in a guide rail of the at least one drawer, a flap, a door or the like serving guide. By this measure, the space required for the adjustment is minimized again, since the transmission means is arranged in the cavity of the guide rail or the like guide and thus no additional space for the transmission means is necessary.

Thus, in particular when installing the device according to the invention an exact adjustment is possible, an adjustment is provided on the guide or the guide rail. By means of this adjustment means, the device can be fixed during installation in its optimum position in which a smooth adjustment of the drawer, the flap, the door or the like is possible.

It has proven to be useful to form this adjustment as a slot, which corresponds to a corresponding screw or clamp connection. Such compounds are simple and can be produced without much material and cost.

In order to store the transmission means particularly smoothly and also to protect against external influences, a guide tube for the transmission means is provided. This extends preferably over the entire travel of the transmission means.

In this case, the guide tube has an opening, via which the drive acts on the transmission means. By this measure, an adjustment of at least one drawer, a flap, a door or the like is ensured, the impairment is minimized by external influences.

This ensures that the at least one drawer, a flap, a door or the like furniture part always moves over a prolonged operation of the adjustment over and over again in its original starting position and not positioned incorrectly within or on the furniture or the vehicle. Such mispositioning may be particularly in the case of drawers not properly closed, Flaps, doors or the like cause injury, since the panel of the drawer, flap, door or the like is no longer aligned with the furniture or vehicle surface, but protrudes from this.

For a particularly uniform adjustment of the at least one drawer, a flap, a door or the like furniture part is ensured, at least two transmission means for adjusting the at least one drawer, a flap, a door or the like are respectively provided.

Furthermore, it has proved to be advantageous that the transfer means is arranged at a drawer on the drawer bottom. Due to the compact design of the transmission means, this results in no impairment of the overall height of the drawer. This ensures efficient storage space utilization of the drawer.

It has proved to be advantageous to arrange the transmission medium in the middle of the drawer bottom. In particular, if only one transmission means is used, this allows a uniform displacement of the drawer.

Furthermore, it has proved to be advantageous to arrange the transfer means in the rear region of the drawer bottom, since thereby the travel of the drawer is maximized. Alternatively, it is of course also possible to arrange the transmission means laterally on the drawer bottom, in particular if two transmission means are used. In this case, the two transmission means should be arranged opposite to the side of the drawer. As a result, a particularly uniform displacement of the drawer is ensured, whereby a uniform force is allowed when moving the drawer.

According to a particularly advantageous embodiment of the invention, the transmission means is arranged in a serving for guiding the drawer, the flap, the door or the like guide rail. This embodiment is very efficient because it does not take up any space in the drawer space. Also by this measure, the storage space is further maximized. Especially with a pitch cable drive this is particularly easy to install in the hollow guide rails.

According to another advantageous embodiment of the invention, the electric motor drive to the furniture or the vehicle can be fastened. As a result, no energy is required to move the electric motor drive itself.

Alternatively, it may of course also be provided to attach the electric motor drive to the drawer, flap, door or the like to be adjusted. This can be advantageous in particular for repairs or maintenance work on the drive, since this is then easily accessible. To be particularly advantageous, it has been found to arrange the electric motor drive in the area between furniture or vehicle and the drawer, flap, door or the like. This arrangement meets in particular optical requirements, since the drive remains invisible in any position of the adjustable drawer, flap, door or the like.

So that the adjustable drawer, flap, door or the like also in case of malfunction of the adjusting device, in particular the transmission means or the electric motor drive is actuated, the electric motor drive from the transfer means and / or the transfer means of the at least one drawer, a flap, a door or like decoupled.

Furthermore, it has proven to be advantageous for a driver attached to the drawer, the flap, the door or the like to be connected to the transmission means. The movement of the transmission means is transmitted by the driver to the drawer, the flap, the door or the like.

With the use of two transmission means, it is provided to fasten catch at two different locations on the drawer, the flap, the door or the like. This also ensures a smooth and trouble-free adjustment of the drawer, the flap, the door or the like. Furthermore, it is provided that the drawer, the flap, the door or the like in case of a defect of the adjusting device manually, preferably by pressing or pulling, can be adjusted.
