The invention relates to a drawer with a bottom, two side walls, a rear wall and a front panel, being provided on both sides of the drawer per a load-side pull-out rail and attached to a furniture carcass support rail and between the support rails and the slide rails rollers, or balls Sliders are provided for load transfer, wherein the Ausziehschienen and the

Support rails with respect to each other to the side and in height unadjustable, preferably free of play, are guided, wherein on each side of the drawer in the front panel an adjusting device is provided with which the position of the drawer to the Ausziehschienen in height and to the side is adjustable.

In modern furniture is required that the drawer is guided sideways, that is, that the drawer does not wobble during the extraction and insertion and there are no jerky movements.

Another requirement that is placed on modern drawers, is that certain adjustment and Emstellmöglichkeiten are given, ie, that the position of the drawer and in particular the front panel with respect to the furniture body is adjustable, so that even with inaccuracies in the assembly of the Carrying or Ausziehschienen superimposed drawers aligned exactly and the joints between the front panels are uniformly wide.

Drawers are known which have at the front end of the support rails VersteUeinrichtungen by means of which the drawer can be adjusted in the side or the height of the furniture. However, this adjustment also require a lateral relative movement between the pull-out rail and the mounting rail, ie, on the other hand, a compact side guide during the entire course of the drawer is not achievable

From DE-OS 27 50 086 and DE-OS 36 32 442 pull-out rails are known, which are adjustably attached to the drawer.

The object of the invention is to improve a drawer of this type. The adjusting device should be easily accessible and compact. It should be possible both a side and a height adjustment.

The object of the invention is achieved in that each adjusting device is held by means of a height adjustable relative to the 25 adjusting member on the front panel of the drawer, which supports in a, preferably T-shaped, guide of the adjusting device in which it is displaceable by means of a height adjustment screw.

According to the adjustment of the rails is done directly to the front panel, which facilitates the positioning, since the position of the front panel is fixed to the furniture body immediately.

Advantageously, it is provided that the adjusting devices have slots aligned parallel to the front panel, through which the clamping screws protrude to fix the lateral adjustment, which respectively engage in a female thread in a horizontal web of the pull-out rails. Thus, a side adjustment of the drawer is made possible in a simple way

For easy installation, the holding parts may have pins by means of which they can be plugged into the front panel.

The height adjustment of the holding parts is advantageously characterized in that the holding parts have a lateral projection which projects through a vertical slot in the adjusting device and in an annular groove in the height adjustment screw

The arrangement of the adjusting advantageously takes place such that the Ausziehschienen C-profile, which ends just before the front panel 40 and that the adjusting means between the front panel and the front end of the C-profile are arranged. As a result, the adjusting device is easily accessible and arranged to save space.

Advantageously, it is further provided that lie in the adjusting the clamping screw for fixing the lateral adjustment and the height adjustment screw in the same plane parallel to the front panel. Both screws can be easily twisted with a screwdriver, the drawer must be pulled out only a short distance from the furniture body. This facilitates the positioning of the drawer.

Hereinafter, an embodiment with reference to the figures of the accompanying drawings will be described in detail.

Fig. 1 shows a longitudinal section through a drawer according to the invention. Fig. 2 shows an elevation of the rear support of the rails, the Fig. 3 shows a top view of the adjusting device from above, the

Fig. 4 shows a top view of the adjusting device from below, Fig. 5 shows a section along the line (EF) of Fig. 3, Fig. 6 shows the attachment of the adjusting device on the front panel, Figs. 7 and 8 show 9 shows a plan view of the adjusting device, FIG. 10 shows a section along the line (AB) of FIG. 9 and FIG. 11 shows a section along the line (CD) FIG. 9.

In the figures of the drawing, the front panel of the drawer is denoted by (1), the rear panel by (2), the side panel by (9) and the bottom by (3).

The pull-out rail (6), as can be seen in particular from FIG. 2, is arranged below the base (3) at an angle between the base (3) and the side wall (9). In Fig. 2, only the left side of the drawer is shown, of course, the right side is formed analogously. In the following description, for reasons of simplicity, only one side of the drawer will be referred to.

The pull-out rail (6) has C-profile and surrounds the mounting rail (7), which is formed with U-profile and at the upper edges outwardly projecting horizontal webs (7 '). Between the pull-out rail (6)

f.

-2AT 394 653 B and the support rail (7) load-bearing rollers are arranged, which are preferably mounted in a carriage. The rollers are not shown in the figures of the drawing; they are arranged according to the prior art. It is important that the leadership of the pull-out rail (6) on the support rail (7) takes place at least substantially free of play.

The mounting rail (7) is fastened via tabs (8) on the body side wall (10).

The pull-out rail (6) carries the front directly behind the front panel (1), the adjusting device (11). The C-profile of the pull-out rail (6) ends at the point (15) immediately before the adjusting device (11).

As can be seen in particular from FIG. 5, a holding part (12) is mounted in a height-adjustable manner in the adjusting device (11) and has a pin (16) with which it can be inserted into a bore in the front panel (1). The pin (16) forms the only anchorage of the pull-out rail (6) with the drawer at the front end of the pull-out rail (6).

At the rear, the pull-out rail (6) is provided with an upwardly projecting tab (4), which has a horizontal oblong hole (17) through which a fastening screw (5) projects (FIG. 1, 2). By means of the fastening screw (5), the tab (4) and thus the pull-out (6) on the rear wall (2) of the drawer attached The pull-out (6) can be adjusted laterally over the width of the elongated hole (17) with loose fastening screw (5) become.

As already mentioned, a holding part (12), which carries the pin (16), by means of which the entire unit adjusting device (11) and pull-out rail (6) is mounted in the front panel (1), is mounted in the adjusting device (11)

The holding part (12) is guided in a T-shaped guide (18) of the adjusting device (11) adjustable in height.

The holding part (12) further has a laterally protruding projection (27) which projects through a vertical slot (20) in the adjusting device (11) and is received in the height adjustment screw (14) by an annular groove (21).

By turning the height adjustment screw (14) of the holding part (12) is moved in the vertical, whereby the drawer of the pull-out rails (6) can be lifted.

On the side next to the height adjustment screw (14) a clamping screw (13) is arranged, which serves to determine the lateral adjustment The height adjustment screw (14) and the clamping screw (13) are in the same plane to the front panel (1).

The clamping screw (13) supports in a nut thread (22) in the upper horizontal web of the pull-out rail (6). Furthermore, the clamping screw (13) protrudes through a slot (23) in the adjusting device (11), which is aligned parallel to the front panel (1). If the clamping screw (13) loosened, the drawer with respect to the pull-out rail (6) and thus to the unit Ausziehschiene (6) and mounting rail (7) over the length of the elongated hole (23) can be adjusted laterally.

Above the height adjustment screw (14) is located in the horizontal web of the pull-out (6) a longitudinal slot (23) corresponding recess (24), so that the lateral adjustment of the drawer does not hinder the height adjustment (Fig. 5).

In the horizontal web of the pull-out rail (6) is laterally a slot (25) into which a nose (26) of the adjusting device (11) protrudes. The nose (26) prevents, together with the slot (25), a rotation of the adjusting device (11) when the clamping screw (13) is loosened.

As can be seen in Figures 7 and 8, the pin (16) is off-center with respect to the support member (12) but is centered laterally with respect to the adjustment means (11).
