In a first embodiment variant shown in FIG. 5, guide walls 7, which are aligned horizontally, parallel to one another and perpendicular to the front surface 5 of the furniture 1, are embedded in a wall 4, 10, 6 and 11 surrounding the furniture front or the carriage 3. In each of the guide rails 7, at least one impeller 8 is guided, which is rotatable on an axis 9, wherein the axis 9 is fixedly arranged on an edge of the furniture front 2, 2 ', 2 ", 2'" or of the carriage 3. To improve the running characteristics of such a furniture front

2, 2 \ 2 ", 2 '" in the furniture body in at least two directly or indirectly interconnected wheels 8 are arranged in each of the guide rails 7. As a result, tilting of the furniture front is effectively prevented during a Einschiebevorgangs.

Instead of the quadruple guide, as shown in Figure 5, a triple or double guide the furniture front 2 _S 2 ', 2 ", 2'" or the carriage 3 in guide rails 7 is conceivable. Possible arrangements of these guide rails 7 are shown in FIGS. 6 to 12 and 14. In the variant shown in Figure 15, in which the furniture front 2, 2 \ 2 ", 2 '" or the carriage 3 are guided in the region of their upper corners in guide rails 7, in the region of the lower corners in addition rollers 12 on the furniture - Front 2, 2 ', 2 ", 2'" or arranged on the carriage 3, which are supported on the top of a horizontally arranged below the furniture front 2 worktop 4 and roll during a sliding operation on the plate 4.

In the embodiment variants shown in FIGS. 13 and 16, only rollers 12 are arranged above impeller axes 13 on the furniture front 2, 2 ', 2 ", 2'" or the carriage 3. In this case, at least two rollers 12 arranged one behind the other in the direction of travel are either arranged only in the lower region of the furniture front 2, 2 ", 2 '" or of the carriage 3 with which the furniture front 2, 2', 2 ", 2" 'or the carriage 3 can be moved on a plate 4 arranged horizontally below the furniture front 2 or in addition there are rollers 12 in the upper one

Fixed area of the furniture front 2, 2 ', 2 ", 2'" or the carriage 3, so that a support of the furniture front 2, 2 \ 2 ", 2 '" or the carriage 3 at a horizontal above the furniture front , 2 ', 2 ", 2'" arranged second plate 6 is made possible.

The area-offset displacement of the furniture front 2, 2 ', 2 ", 2'" preferably takes place electrified. For this purpose, the furniture preferably has an electric drive unit with which the furniture front 2, 2 ', 2 ", 2'" is displaceable. A first embodiment variant of such an electric drive unit is shown in FIGS. 17 to 19. The electric drive unit is designed here as a toothed belt drive.

As shown in FIG. 17, a drive motor 19 is arranged in the carriage 3, which drives a drive axle 17 via a toothed belt 18. The drive shaft 17 pierces in their respective end regions a plate 22 fastened vertically to the carriage 3. Behind the plate 22 sits on the ends of the drive axle 17 in each case a toothed wheel 16 with external teeth. About this gear 16, a toothed belt 15 is placed, which is pressed from the right and left of the gear 16 arranged pulleys 14 against the gear 16. The tooth- - -

As a result, in the region of the toothed wheel 16 and the deflection rollers 34 in the shape of an omega, the ring 15 is placed around the toothed wheel 16, which results in secure toothed belt clamping.

The toothed belt 15 and the guide rollers 14 are in a first guideway

20 of the guide rail 7, wherein the toothed belt 15 is fixed end with adjusting elements 28 in the guide rail 7. By means of the adjusting elements 28 of the toothed belt 15 is horizontally displaceable and fixable.

In order to increase the ease of movement in the guide rail 7, the guide rail 7 has a second guide track 21, in which spaced as far as possible wheels 8 are guided, which are fixed to the right and left of the pulleys 14 on the plate 22. The guide track 21 and correspondingly the wheels 8 are offset from the first guide track 20 and the pulleys 14 running therein, as can be clearly seen in particular in FIG.

As can be clearly seen in FIG. 17 and also in FIG. 20, the plate 22 has two oblong holes 27, through which screws 26 are set, which makes the plate 22 vertically adjustable on the carriage 3 in a direction z.

As can also be seen in FIG. 20, a similar vertical adjustment of wheels 12 running on a plate 4 of the furniture body via a plate arranged on a carriage 3 in the lower region of the carriage is also conceivable.

As shown in FIG. 21, the furniture front 2, 2 ', 2 ", 2'" is arranged on the carriage 3 in an angle-adjustable manner. For this purpose, in the back of the furniture front 2, 2 \ 2 ", 2 '" preferably ball joint shells 33 are inserted, in each of which a ball head 31 designed as an end of a rotatably mounted in the carriage 3 knurled knurled 29 arranged, which via a thumbwheel 32nd and one in the

Wall 24 of the carriage 3 screwed screw thread 30 is adjustable. As a result, a Femjustierung the furniture front 2, 2 ', 2 ", 2'" with respect to the front surface 5 of the furniture 1 can be made in a simple manner. FIGS. 22 to 25 show a further embodiment variant of the drive unit. Here, the drive unit is designed as an electrified cable winch drive. In this case, a holding element 34, the side of the furniture front 2, 2 ', 2 ", 2'" or is fixed to the carriage 3, moved by an electrically driven cable drum 35 on which a cable 39 is wound for each support member 34 which is guided at at respective ends of the guide rail 7 'arranged deflection rollers 37, 38 and fixed via a fastening element 44 on the holding element 34. The cable 39 is not continuous, but is set with its ends at different positions on the cable drum 35 such that during operation one end winds up, while at the same time the other end unwinds. For a slip-free method of the carriage 3 is guaranteed.

The guide rail 7 'has two parallel to the longitudinal axis of the guide rail extending webs 36, which together with the outer walls of the cross-section

Omega-shaped guide rail T channels for the cable 39 form. On the back of the support member 34, two wheels 40 are arranged, which run in a guideway, which is formed by the mutually facing sides of the webs 36. The width of the holding elements 34 (viewed in the direction of displacement y) corresponds to the width of the furniture front 2 to be held or the width of the carriage 3 to be held.

To enable a horizontal in the plane of the front surface of the furniture horizontal adjustment of the furniture front 2, 2 ', 2 ", 2'", the holding element 34 at perpendicular projecting from a rear wall of the support member 34 legs 41 slots on which the furniture front 2, 2nd ', 2 ", 2'" or the carriage 3 can be set horizontally adjustable. Additional webs 42, 43 of the holding element 34, which protrude vertically or obliquely upward from the back of the holding element in the direction of the furniture front 2, 2 ', 2 ", 2'" or the carriage 3, also allow a secure vertical Hold the furniture front 2, 2 ', 2 ", 2'" or the

Carriage 3 on the holding element 34th

In the embodiment variant of the furniture 1 shown in FIGS. 26 to 28, the furniture front 2, 2 ', 2 ", 2""is parallelogram-like laterally upwards over webs 46 pivotally mounted on the carriage 3. As can be seen in particular in Figure 28, with such an arrangement, another furniture element 47, which is arranged above the carriage 3 in the furniture 1, after a displacement of the carriage 3 to the rear, via a lift assembly down in the front of the carriage 3 vacated space are lowered. Furthermore, at the

Rear of the carriage 3 of the furniture front 2, 2 \ 2 ", 2 '" corresponding back member 45 is arranged so that the back of the furniture in the pushed back position of the carriage 3 can also be closed flush by the back member 45.

FIGS. 29 to 32 show two different design possibilities, such as an improved volume utilization of the space in front of the furniture front 2, 2, 2, 2 "is made possible when the furniture front 2, 2, 2, 2" is pushed completely backwards. For this purpose, a chassis 51, to which the furniture front 2, 2 ', 2 ", 2'" is fastened, and which can be moved in linear guide rails 7 between a front and a rear position, is formed with a telescopic arm 50 on which one of two arranged in the guide rail 7 wheels 8 is arranged. Furthermore, a locking lever 49, with which the telescopic arm 50 can be retained in an extended position, is arranged on a rear wall 48 of the chassis 51. As a result, the running in the respective guide rails 7 wheels 14 to avoid jamming of the chassis 51 are widely spaced apart in the greatest possible distance.

If the chassis 51 is displaced in the direction of the maximum position remote from the front surface 5 of the furniture 1, then the locking lever 49 abuts against a rear wall of the furniture 1 and thereby moves out of its position blocking the telescope 50 so that the telescopic arm 50 in the chassis 51 is retractable. In its end position, the chassis 51 has only a reduced depth b, whereby the usable volume in front of the furniture front 2, 2 ', 2 ", 2'" is increased.

In an alternative embodiment, shown in FIGS. 31 and 32, the guide rails 7 "are made bent and the chassis 51 consists of two sections separated from each other by a hinge 52, which during a Displacement of the chassis 51 in the direction of the maximum of the front surface 5 of the furniture 1 remote position from a coaxially extending position in a kinked position are pivoted, with one of the furniture front 2, 2 ', 2 ", 2'" remote impeller 8 As a result, the initial depth a of the chassis 51 shown in Fig. 31 can be extended to a depth b of the chassis 51 shown in Fig. 32. As shown in Figs.
