A multi-part pull-out guide 3 is arranged on the base 1 of a tall cabinet 2, on its pull-out rail 4 a vertically standing pull-out frame 7 is fixed is with a front vertical frame leg 5 and a rear vertical frame legs 6 and upper and lower horizontal frame legs 8 and 9. An upper horizontal frame leg 8 engages Guide 10, which has the task of stabilizing the pull-out frame. The single ones Frame legs can optionally be telescopic and can be extended or shortened to the dimensions of the pull-out frame to adapt a tall cabinet 2. Between the frame legs 5 and 6 Several insert baskets 11 can be suspended, only one of which is shown here is. A front panel 12 can be fixed on the front vertical frame leg 5, the tall cabinet 2 to the front when the pull-out guide 3 is retracted closes. To fix this front panel 12 on the pull-out frame 7 are on whose front vertical frame leg 5 dowel pin 13 is provided, the protrude into corresponding holes on the front panel 12 and here are arranged on spars 14. These spars 14 extend transversely to the longitudinal direction of the front frame leg 5.

A spar 14 carries dowel pins 13 at its two ends, which are conventional can be designed as expansion dowels. The spread is made by twisting of the lever 15 arranged on the rear of the spar 14. These dowel pins 13 can also be designed so that one of the two dowel pins 13 is adjustable relative to the other in such a way that their distance changed from each other. In this case, one of the dowel pins is 13 µm an eccentric axis parallel to its central axis is rotatably supported. In this case too, the rotation is effected with the lever 15. Instead of Twist around an eccentric axis can be the one anchor relative to the other dowels slidably mounted along the connecting straight line of these dowels his. However, this is not shown in detail here. Laying down this Holmes 14 with the attached dowel pin 13 on the front frame leg 5 serves a clamping part 16, which in a on the front of the frame leg 5 recess 17 is insertable.

This clamping part 16, which is designed as an expansion block, has a U-shaped profile piece 18 on. Between the cheeks of the U-shaped profile piece 18 is a Jaws 19 stored. Profile piece 18, jaws 19 and spar 14 are penetrated by a pin 20, one end of which a widened head 21st has and the end face has a longitudinal bore (Fig. 8). The Wide head 21 of the pin 20 lies in a longitudinal groove 22 of the spar 14. In the bottom this longitudinal groove 22 has an elongated hole recess 23 in the spar 14, which extends in its longitudinal direction.

The clamping jaws 19 consist of a profile piece with a U-shaped cross section 24, the web 25 connecting the side cheeks an outer, approximately gable roof-like Has shape (Fig. 8). Between the cheeks of this profile piece 24 of the jaw 19 is a rubber-like fitting 26 is held, the opposite the longitudinal edges of the cheeks of the profile piece 24 protrudes somewhat. This The jaws 19 are connected to the pin 20 by the screw 27. Between the outer profile piece 18 and the jaws 19 is a pin 20 penetrated expansion member 29 is provided which is rotatable about this pin 20 is stored. This disc-shaped expansion member 29 has a laterally projecting one Swivel lever 30 connected by a in one cheek of the Profile piece 18 recessed, slot-like opening 31 protrudes. The expansion member 29 is formed as a disc, one side of which is arranged diametrically to one another Wedge slopes, which with the gable roof-shaped web 25 of the Profile piece 24 interacts directly. Instead of the gable roof shape of the Web 25 and the wedge bevels of the expansion member 29 could the web 25 and that Spreading member 29 also each have a screw surface that abut each other and a displacement of the expansion member 29 when the latter is rotated Clamp jaws 19 cause.

On its outer surface, the profile piece 18 carries pairs Guides 32, which extend across the width B of this profile piece 18 and whose sides facing away from the spar 14 are arc-shaped in the exemplary embodiment shown run. Seen from the spar 14 is this arcuate course the guides 32 convex. The end face of the clamping part 16 is chamfered (Fig. 6), the bevel of one end face 35 being approximately 45 °. The cone 20 is offset from the longitudinal center of the clamping part 16 and points from the beveled end face 35 of the clamping part 16 at a distance which is greater than its half length.

The guides 32 can also protrude the width of the profile piece 18, wherein on the profile piece, a contact plate for the spar 14 is attached, which is on both sides extends beyond the profile piece and at their upper and lower Edges the guides 32 are provided. On the outside of the profile piece 18 of the clamping part 16 is one adjoining one of the guides 32 for the spar 14 and heel-like, extending over the width of the profile piece Increase 33 provided.

To accommodate the clamping part 16 in the front, designed as a box profile Frame leg 5 is an extending across the width of the box profile Recess 17 is provided, the front edge 34 corresponding are formed to the outer boundary surfaces which are curved here the guides 32 for the spar 14. The distance between these front edge edges 34 from each other is slightly larger than the mutual distance of the curved Boundary surfaces of the guides 32 (see. C in Fig. 3). The width B of the Clamping part 16 is slightly smaller than the inner width of the box section.

Around the clamping part 16 with the spar 14 in the recess 17 of the frame leg 5 use, the pivot lever 30 is initially opposite the 3 and 5 visible position pivoted by 90 °. This will make the Clamping part 16 relaxed. Now this clamping part 16 is in the recess 17th introduced, which facilitated by the beveled end faces of the profile piece 18 is. If the clamping part 16 is threaded into the frame leg 5, it can it can be shifted somewhat in the axial direction because of the axial length of this recess 17 is larger, e.g. by about 1 cm than the distance C of the top guide 32 from the lower elevation 33 (Fig. 3). Is the clamping part and thus the Spar 14 properly positioned, then the pivot lever 30th pivoted back into its position shown in Figures 3, 5 and 9, and the clamping member 16 is activated by the expansion member 29, which is located within of the frame leg 5 formed as a box profile braced.

In the vertical frame leg 5, an actuator 41 is inserted, of which in Fig. 2 a part of the adjusting wheel 42 is visible, which is used for the vertical adjustment of the Threaded spindle 43 is used. First and second bevel gears are in a housing 44 45, 46, which mesh with each other, rotatably mounted. The first bevel gear 45 is rotatably mounted on a shaft 47 which can be rotated by the adjusting wheel 42. Instead of the setting wheel 42, a non-circular recess could For example, a hexagon may be formed in the shaft 47, in which for Rotating the first bevel gear 45 a tool can be inserted. The first Bevel gear 45 and shaft 47 can also be formed in one piece.

The second bevel gear 46 has an internal thread 48 that the threaded spindle 43 records. By turning the adjusting wheel 42 is the first Bevel gear 45 and via this the second bevel gear 46, the axis 49 is arranged vertically, driven. As a result, the non-rotatably mounted Threaded spindle 43 moved in the vertical direction. To secure the threaded spindle 17 in the embodiment according to FIG the threaded spindle with a longitudinal groove extending in the axial direction 50 provided, into which a guide pin 51 arranged on the housing 44 protrudes. Instead of the longitudinal groove 50, the threaded spindle could also be from an elongated hole be enforced. The shaft 47 could also pass through this. In the 16 has the threaded spindle 43 for securing against rotation opposed flattened areas 52 on which guide surfaces 53 of the housing 44 abut.

The first and second bevel gears 45, 46 are at right angles to each other arranged and stored in the housing 44 on the same walls. For storage of the first bevel gear 45, this has two mutually angled Conical surfaces 54, 55, which abut against these conical surfaces 54, 55 Portions of the walls of the housing 44 are added. For storage of the second bevel gear 46 in the housing 44 has a stepped Approach 56, which is received by a step 57 in the housing.

The housing 44 is in a corresponding recess on the back of the vertical frame leg 5 inserted and fastened in this. Will be at in the frame leg 5 inserted clamping part 16 on which the front panel 12th is fixed, the pivot lever 30 is pivoted into the release position, so the Clamping part 16 by actuating the setting wheel 12 from the setting part 41 in a vertical position Direction can be adjusted, the spar 14 can also be offset in its longitudinal direction become. The weight of the front panel 12 must be in this adjustment are not carried by a person assisting in the adjustment, but is also on the pull-out frame when the clamping part is open transfer. After adjusting the front panel to the desired one Position, the swivel lever 30 is moved back into its clamping position, in which it lies laterally on the box section or on the frame leg 5. The The clamping part is thereby clamped in the frame leg 5 and the spar 14 becomes clamped on the clamping part.

In the embodiment described above, the clamping or Clamping force that can be exerted by the clamping part 16 in the plane of the Pull-out frame 7 and at right angles to the frame leg 5.

11 to 14 now show an embodiment of the clamping part 16, at the clamping and clamping force can act in two directions, on the one hand in the Level of the pull-out frame 7 and at right angles to the frame leg 5 and on the other hand, at right angles to the level of the pull-out frame 7 and to the frame leg 5. In this embodiment, the jaws 19 in two Partial jaws 36 and 37 divided lengthways. Between the sides facing each other of these two partial jaws 36 and 37 is the pin 20, which is one of the here Rotational symmetry has a different cross-section, for example an oval Cross-section. This part of the pin is also with the pivot lever 30 rotatably connected, as well as the expansion member 29, which also in this embodiment is available, but that of the first mentioned construction parts in 11 to 14 is almost completely covered, but which has a structure like this discussed in connection with the first discussed embodiment has been. The cheeks of the profile piece 18 have window-like recesses here 38, and outer elevations 39 are formed on the partial jaws 36 and 37, the dimensions corresponding to the window-like recesses 38 are formed and protrude through them with play. Will the Swivel lever 30 pivoted in the sense of the above statements, so the Part jaws 36 and 37 by the expansion member 29 in the axial direction of the pin 20th offset and because of the cross-section of the pin 20 mentioned additionally laterally, the outer sides of the elevations 39 on the inner walls of the frame leg 5 friction fit. With the one discussed here The embodiment is divided into two parts. It consists of the head here 21 having part and a rotatably connected to the pivot lever 30 Sleeve with the mentioned cross-section deviating from the rotational symmetry, wherein the expansion member 29 is integrally formed on the pivot lever 30.

15 shows a further detail in view, which serves to facilitate assembly: The longitudinal groove 22 in the spar 14 has at one of its ends the passage of the Head 21 of the pin 20 enabling widening 40. This longitudinal groove 22 is formed like a keyhole. This makes assembly easier.

The components described here can without Tools are connected and assembled.

Although the use of a clamping part, which in the front frame leg can be jammed, is preferred, it would also be conceivable in principle and possible to use a clamping part, which such a jamming in Frame legs are not allowed, but only clamps the crossbar 14. In this case, storage in the vertical direction would only be done by the control element.
