As in 1a shown, has a drawer 10 trained movable part of a hinted piece of furniture 1 on two sides, in which it is in the piece of furniture 1 is slidably received and movably mounted, each a guide rail 14 on. Preferably at least one guide rail 14 is with a runner 15 a linear motor 2 Mistake. The at least one runner 15 is formed by a series of magnets or of magnetizable material, wherein in the case of magnets, these preferably alternate at predetermined intervals with respect to the orientation of the magnetic poles.

In one the drawer 10 receiving furniture of the piece of furniture 1 are corresponding to the guide rails 14 on lateral walls or wall sections of the furniture 1 guide rails 12 arranged in which the guide rails 14 the drawer 10 and with it the drawer 10 self-guided is stored. In the or the guide rails 12 that with a guide rail 14 Corresponds with a runner 15 is equipped, is or are each a stator 13 of the respective linear motor 2 arranged. The respective stator 13 consists essentially of a series of electrically energizable coils. The coils are along the extension of the guide rail 12 arranged such that they upon application of a voltage with the respective rotor 15 interact in such a way that the runner 15 and with it the drawer 10 in the opening or closing direction of the drawer 10 can be moved.

To determine if the drawer 10 is fully open or closed, additional sensors may be provided. By way of example, an end stop switch 11 for detecting a closed position of the drawer 10 and a roller switch 16 for detecting an open position of the drawer 10 shown.

When closing the drawer 10 it bumps against the limit stop switch shortly before its closed position 11 and press this. A drive circuit of the respective linear motor, in the simplest form a controller, switches due to the current closing operation and detecting the operation of the end stop switch 11 the respective stator 13 from. Due to a now possible generator operation of the at least one linear motor 2 the drawer is slowed down in its movement. Ie. by means of the at least one linear motor 2 At the same time a stop shock absorption can be realized.

In its closed position and when opening the drawer 10 pushes it against the roller switch 16 so that it is in on position. Becomes the linear motor 2 operated in drawer opening direction, and is the drawer 10 almost or fully opened, the drawer arrives 10 out of engagement with the role of the roller switch 16 , the roller switch 16 is then in off position. The drive circuit switches on the basis of the current opening operation and detecting the state change of the roller switch 16 the respective stator 13 from.

One directly coupling the switches to the drive circuit such, that an operation of a switch directly to shutdown of the stator is not possible. The effectiveness the switch is dependent on the movement of the drawer.

Instead of or in addition to limit switch 11 and roller switches 16 can be at least one stator 13 have a Wegmesssensor, which is preferably formed by means not shown Hall sensors. This makes it possible, in addition to the open and closed position of the drawer 10 additional intermediate positions or distances traveled by the respective runner 15 or linear motor 2 to investigate.

According to another, in 1b shown second embodiment of the invention are guide rails 14 each side below the drawer 10 arranged. The magnets or the magnetizable material of the runners 15 are inside the side walls of the drawer 10 arranged. Alternatively, the guide rail 14 with the respective runner 15 at the bottom of the drawer 10 be fastened for example by means of screws. In the storage room for the drawer 10 of the furniture 1 are corresponding support or guide rails 12 arranged the stators 13 have, inasmuch as the corresponding guide rail 14 a runner 15 having.

Instead of Endanschlagschalter- and roller switch assembly in 1a are right and left in 1b in the receiving space for the drawer 10 two arranged in the drawer movement direction strips arranged. The bars each have two roller switches 16 arranged, the detection of the open or closed position the drawer 10 enable. The provision of two strips is used for redundancy, if one of the roller switches 16 should fail. In principle, one bar is sufficient. The bar also serves for safety. For example, in a cabinet with several, one above the other and adjacent to each other arranged drawers 10 could be a bottom drawer 10 be so packed that when closing the lower drawer 10 the content against a front surface of a roller switch 16 in 1b an upper drawer 10 and thus releases it from the anchorage. In an example in 1b shown strip, extending from an insertion opening for the drawer 10 continuous at least until the rear roller switch 16 extends, this danger does not exist, the contents of the respective drawer 10 finds no attack surface.

The bar is of course also in the 1a used variant shown. The only difference is that the rear roller switch 16 eliminated.

1c again shows a drawer 10 according to a third embodiment of the invention. As can be seen, this is at least a linear motor 2 not integrated into a guide rail system. Instead, the runners 15 the linear motors 2 in an upper section of side panels of the drawer 10 integrated so that they flush with an upper surface of the respective side wall Fl and are preferably encapsulated against mechanical influences, for example by means of a potting compound. The casting compound also allows the formation of a rotor module, which facilitates assembly.

Above the respective rotor is on a respective side wall of the receiving space for the drawer 10 a stator 13 arranged such that he with the respective runner 15 can interact. The stator 13 can be similar to the one in 1b shown roller switch 16 be integrated in a bar. It is also not necessary that the respective stator 13 not over an entire depth from the insertion opening for the drawer 10 To extend to the rear wall can advantageously roller switch and stator 13 be integrated in one and the same bar. Is the runner 15 protected against mechanical stress, the at least one roller switch 16 at the runner 15 also do no damage.

About a suspension and an arrangement of rollers 32 is the sliding door wing 21 stored stored. Im in 2c Example shown are on each suspension two Rol len 32 arranged such that a roll 32 on a lower track or guide rail 31 unrolls and takes on each other's role 32 on an upper track or guide rail 31 supported. This double support serves to avoid vertical movements of the sliding door leaf, so that stator 22 and runners 23 a linear motor 2 always have a predetermined minimum distance from each other. The upwardly supporting rollers and the upper guide rail 31 can also be omitted. The runner 23 is at an upper edge of the sliding door leaf 21 for example by means of a in 2d attached shown U-shaped clamping profile. The stator 22 is in the lower guide rail 31 integrated or attached to a lower edge of this, as well as in 2d shown.
