Description

The invention relates to a drawer frame with a fastening device for releasably and positionally adjustable attaching a front panel to a drawer container, wherein the front panel is releasably connectable via a pre-assembled on the front panel connecting element with the fastening device and wherein the container for adjusting the position of the front panel in the height direction, a first control element is assigned , as well as a drawer with such a drawer and a cabinet with a drawer and drawer.

Drawer frames generally form a stability-providing part of a drawer. Most of these drawer frames are formed in the lower side portions of the drawer, where the drawers are mounted on pull-out guides, the pull-out guides themselves being mounted in turn in a furniture body of a piece of furniture.

As from the generic WO 2009/006651 A2 As is known, in the region of the drawer frame facing towards the front panel, a fastening device is arranged on which a front panel is fastened. In addition, various adjustment mechanisms are arranged in the region of the fastening device, which allow a positional adjustment of the front panel, for example. In height, in side and in the direction of inclination. The adjusting elements for height and tilt adjustment are assigned to the container (frame), while the adjusting element is assigned to the side adjustment of the front panel. As can be seen in this document, this whole mechanism requires a relatively large amount of space in the attachment area and is elaborately designed with many parts.

The DE 43 05 074 A1 basically shows a drawer trim fitting that allows height and lateral adjustment of the front panel relative to the drawer side wall. The height adjustment is carried out by a support pin and a screw relative to a fastening part (longitudinal slot). The height is also fixable by a grub screw. In contrast, the lateral transverse adjustment of the front panel is directly connected to a connected to the front panel - and thus the front panel and not the drawer or its side wall associated - attachment part and there on the slots. A Transverse displacement along the elongated holes can only be done manually with loose fixing screws without a proper actuator.

Also for them EP 0 096 898 is true that for the side adjustment, the front panel itself must be moved laterally with the attached mounting bar. No active actuator for Seitenvesterstellung is shown.

The same applies to the DE 38 01 103 A1 , in which after a lateral displacement, a fixation by rotation of an eccentric takes place.

In the same way, this also applies to the non-generic AT 304 802 B , There are also given according to this document only slots for the lateral adjustment between a support plate and the front panel. A responsible for the height adjustment screw in conjunction with an opening is not assigned to the container, since in the release position of the front panel with pre-mounted support plate, the screws and threaded holes in the support plate - and thus the front panel - remain.

Even in the alien DE 85 31 752 U1 the existing set screws are assigned to the connecting element (holding part). In addition, there is no actual actuator for the side adjustment there.

Also are in the alien DE 20 2007 011 518 U1 Assigned bolt for height and lateral adjustment of a device connected to the front panel. That is, the connecting element can be solved only with the bolts of a, the container associated support member or the frame, whereby no adjusting elements are associated with the container.

In a similar way also shows the strangers EP 1 639 917 A1 the fastener associated screws, in addition, no actual Seitenverstellelement is taught.

Also at the DE 34 15 851 A1 The screws for height adjustment and for lateral adjustment of the front panel and its holding part are assigned.

According to the DE 36 20 450 A1 is the container associated hook height and page adjustable. Thus, the control elements do not engage any connecting element associated with the front panel.

The object of the invention is to provide a comparison with the prior art improved, less complicated and simplified drawer frame with fastening device. In particular, the space requirement should be reduced. Nevertheless, the functionality with respect to the disengagement and the position adjustment of the front panel should essentially be maintained.

This object is achieved for a drawer with the features of the preamble of claim 1 according to the invention that the container for adjusting the position of the front panel in the lateral direction, a second control element is assigned, wherein at least the first and second actuator on the same plate-shaped part of the connecting element attack, at Actuation of the second actuating element, the front panel on the plate-shaped part of the connecting element in the lateral direction is movable relative to the container. Above all, since the part of the connecting element, on which the first and the second actuating element engage, is substantially plate-shaped, a very narrow alignment of the fastening device is provided. In particular, the drawer is not widened compared to the prior art in the lower area, whereby the entire drawer wall is not wider than 15 mm. Preferably, the width is less than 11 or even a maximum of 8 mm.

Preferably, the part of the connecting element, on which both the first and the second actuating element engage, integrally formed. But it is also quite conceivable that said part of the connecting element consists of several pieces, which in the mounted state to each other have a fixed, non-adjustable positional relationship and still form the same part as claimed in claim 1.

It can preferably be provided that the plate-shaped part has indentations, wherein the adjusting elements engage in these indentations.

A further preferred embodiment variant of the invention can provide that during the adjustment of the second control element, preferably in the form of a screw, the plate-shaped part moves in the lateral direction relative to the container and that when adjusting the first control element, preferably in the form of an eccentric, the plate-shaped part moved in the height direction relative to the container. In order to enable these movements of the different control elements on the same plate-shaped part, must - in contrast to the prior art - sufficient clearance when not just actuated actuator be provided so as not to hinder the adjustment by the other actuator. For this purpose, it can be preferably provided that on the one hand between the second actuator and indentation of the plate-shaped part in the vertical direction game and this allows an adjustment of the first adjusting element in the vertical direction and on the other hand between first actuator and indentation of the plate-shaped part in the lateral direction game and this is an adjustment of second actuating element in the lateral direction permits.

In order to generally allow loosening and connecting the front panel to the drawer, it may be preferably provided that the container for releasably securing the front panel to the drawer is assigned a locking device, wherein by adjusting the locking device from a locking position to a release position, the connecting element from the container is solvable. In this case, a spring-mounted catch part may be provided which automatically pulls the penetration of the connecting element of the front panel to the drawer, after which the locking takes place.

In order to achieve the smallest possible execution even when providing a locking device, it is preferably provided that the locking device engages the plate-shaped part of the connecting element. Again, there should be enough clearance for the side and height adjustment of other control elements.

It should not be ruled out for the invention that a third, preferably also on the plate-shaped part of the connecting element attacking, adjusting element for tilt adjustment of the front panel is provided.

Preferably, it can further be provided that the adjusting elements and the locking device are rotatable, preferably actuated by a screwdriver, adjustable and self-locking. The individual control elements and the locking device can be reached either from the outside or from the inside by the screwdriver.

Since a drawer is attached to a pull-out guide on both its side areas, drawer frames are usually present on both sides in a drawer. The drawer frame according to the invention can be present with the fastening device either only on one side or on both sides. In any case, the front panel on the other drawer should allow the adjustments made. If the adjusting elements or the locking device is provided on both sides, the adjustment should be made on both sides.

Protection is also desired for a drawer with a drawer frame according to one of claims 1 to 11, and for a piece of furniture with a drawer according to claim 12.

Fig. 1 The drawer 15 consists essentially of the drawer container 8 and the front panel 7, the drawer container 8 a drawer bottom 31, the drawer rear wall 32 and the drawer 5 including frame attachment 8 includes. The drawer 5 is in Fig. 1 as wide as shown in the prior art, resulting in a small filling volume of the drawer 15 by itself.

Fig. 2 schematically shows a part of the drawer 5, which is connected to a container rail 19, and a first adjusting element 2 for adjusting an intermediate plate 20 in the height direction HR comprises. On this intermediate plate 20, a further adjusting element 1 is arranged for adjusting the front panel 7 via the connecting element 10 in the lateral direction SR.

As in Fig. 3 can be seen, this invention in Fig. 2 shown intermediate plate 20 is no longer needed. Much more are the drawer 5 at least two adjusting elements 1 and 2 assigned for adjustment in the lateral direction SR and height direction HR, both attacking the same part 10 of the connecting element 9 and by the adjustment of this plate-shaped part 10 on the holding extensions 12 (preferably in the form of dowels ) the front panel 7 relative to a drawer container 8 position change. In addition, the fastening device 6 may also have a locking device 4, which preferably acts on the same plate-shaped part 10 of the connecting element 9. "The container Assigned "means according to the present invention, that the adjusting elements 1 and 2 are arranged with removed front panel 7 (with connecting element 9 mounted thereon) on the drawer 8 (or the frame 5 and its attachment device 6).

Fig. 4 shows the essential components of the fastening device 6 of the drawer 5 in an exploded view. Container side, the fastening device 6 comprises substantially the U-profile 22, in which the individual control elements 1 and 2 and the locking devices 4 and 4a are arranged, and front panel side, the connecting element 9. The drawer 5 consists essentially of the U-profile 22 and At this drawer 5 a container rail 19 is attached to the underside of the drawer bottom 31, via which the entire drawer 15 can be attached to a pull-out guide, not shown.

Essential parts of the fastening device 6 are the second control element 1, which comprises the worm 13 and the actuating part 26, the first adjusting element 2 for adjustment in height direction HR, which comprises the eccentric 14 and the positioning nut 25, and the two locking elements 4 and 4a, which each comprise the locking screw 23, the locking element 24 and the locking spring 30. In the receptacle 27 of the U-profile 22, the connecting element 9 mounted thereon is introduced when attaching the front panel 7. This connecting element 9 has a plate-shaped part 10 with various indentations 11, each of which acts on the individual adjusting elements 1 and 2 or the locking devices 4 and 4a. The holding extensions 12 are easily elastically connected via bending elements 28 connected to the plate-shaped part 10. The recesses 11, which correspond to the locking devices 4 and 4a and the second control element 1, have a sufficient clearance S _HR in the height direction HR to the height adjustment with the first control element 2, which engages in the second indentation 11 seen from above to allow.

In Fig. 5 is the uniform width and at the same time relatively narrow version of the fastening device 6 can be seen. This can be an equally narrow and evenly wide Zargenaufsatz 18 on the base part 21 and on the U-profile 22 of the drawer 5 are attached. In contrast, especially shows the Fig. 3 of the WO 2009/006651 A2 a drawer frame becoming increasingly wider in the lower area, since the entire parts of the fastening device otherwise would not have room, whereby the interior of the drawer container is substantially reduced.

In detail D, the fastening device 6 is shown in the assembled state, wherein the plate-shaped part 10 of the connecting element 9 are connected via these protrusions 11 with the individual control elements 1, 2 and the locking device 4 with the drawer 5.

In Fig. 6 shows the section A by the screw 13, the normal position of the plate-shaped part 10 without adjustment in the lateral direction SR.

In Fig. 7 shows the detail section B through the first control element 2 and its eccentric 14, the normal position of the plate-shaped part 10 in the height direction HR, where already enough for the adjustment in the lateral direction SR game S _{SR is} present. The positioning nut 25 has numerous nubs in corresponding recesses on the U-profile 22 (see Fig. 4 ), whereby a self-locking is given after adjustment of the eccentric 14.

In Fig. 8 the detail section C shows a section through the locking screw 23 of the locking device 4, wherein the locking element 24 engages in the locking position V on the part 10. Also in this area, the plate-shaped part 10 in the U-profile 22 enough clearance S _SR in the lateral direction SR to allow the lateral adjustment by the second actuator 1.

In Fig. 9, this lateral adjustment is shown, wherein the plate-shaped part 10 of the connecting element 9 when inserted into the receptacle 27 in a Verklemmbereich 29 between the two sides of the U-profile 22 passes. By rotating the worm 13 of the actuating element 1, the plate-shaped part 10 from the position shown in FIG. 9 and Fig. 10 in the position according to Fig. 11 moves, whereby the position of the front panel 7 relative to the container 8 is changed. As it were, a pivoting of the plate-shaped part 10 takes place around the Verklemmbereich 29. To compensate for the extreme position shown in Fig. 9 inclined position of the retaining extension 12 in the front panel 7, the bending elements 28 (see Fig. 4 ) is provided in the connecting region between the holding extension 12 and plate-shaped part 10.

As in the Fig. 9 to 11 it can be seen, the frame attachment 18 is already slipped over the entire fastening device 6 and the U-profile 22, wherein the individual control elements 1 and 2 or the locking device 4 is accessible through the openings in the frame attachment 22. The operation can - in contrast to the illustrated embodiments - also done from the outside.

The FIGS. 12 and 13 show extreme positions of the first control element 2, wherein according to detail G, the plate-shaped part 10 with respect to the U-profile 22 in the height direction HR at the very bottom and in Fig. 3 the plate-shaped part 10 is arranged at the top in relation to the U-profile 22 in the height direction HR. By rotation of the eccentric 14, the plate-shaped member 10 is moved up and down.

Fig. 14 shows in detail J the locking element 24 of the locking device 4 in the locking position V in the plate-shaped part 10. By contrast, in detail K of Fig. 15 the locking member 24 is brought by turning the locking screw 23 in the right arrow direction against the spring force of the locking spring 30 in the release position L.

As in Fig. 17 can be seen, the locking of the locking device 4 can be done by locking the locking element 24 in the locking groove 34 in the plate-shaped part 10. For the adjustment in height direction HR enough clearance S _{HR is} provided in this locking groove 34, wherein in each height position must be guaranteed that the locking element 24 can reach the locking position V in the plate-shaped part 10. As well as out Fig. 17 it can be seen, the locking element 24 automatically snap when inserting the plate-shaped part 10, wherein the locking member 24 can slide against the spring force of the locking spring 30 at the upper end of the plate-shaped part 10 partially. Preferably, the recess 11 itself forms the locking groove, in which the locking element 24 snaps into the locking position V. This shows the Fig. 18 the position of the locking element 24 when the part 10 in the U-profile 22nd inserted while the locking member 24 is rotated against the spring force of the spring 20 until the full insertion of the part 10, the locking element 24 snaps into the upper recess 11 and the locking position V passes. In other words, the locking device 4 is designed as a buttoned, spring-loaded rotary latch. In general, it should be noted that the locking device 4 may be single or double (reference numerals 4 and 4a) provided in the fastening device 6.

In Fig. 16 is shown that the specified in claim 1 same part of the connecting element 9 does not necessarily have to be in one piece. Rather, this same part 10 may consist of two different sections 10a and 10b, but in the mounted state on the front panel 7 to each other have a fixed, non-adjustable positional relationship.

A significant advantage of the control elements 1 and 2 shown in this application is that they have a so-called "memory effect". That is, when the connecting element 9 is connected after loosening again with the other parts of the fastening device 6, the adjusting elements 1 and 2 remain by their self-locking always in the previously occupied position, which is not after removing and replacing the front panel. 7 a new position adjustment must be made. Although preferred embodiments of the present adjusting elements 1 and 2 are the worm 13 and the eccentric 14, it should not be ruled out that other self-locking adjusting elements such as gear drives or other non-self-locking adjusting elements in a similar manner, the adjustment of the front panel 9 relative to the drawer container 8 on allow one and the same part 10 of the connecting element 9.
