Description

The invention relates to a furniture fitting for fastening a front panel to a drawer frame, with a front panel associated preassemblable on the front panel connecting element and a drawer associated with the frame, fastening device connectable to a frame plate, an adjusting plate and on the frame plate, in particular rotatable arranged and acting on the adjusting plate adjusting elements, by which the adjusting plate relative to the frame plate in the vertical direction and in the lateral direction is adjustable. In addition, the invention relates to a drawer with such a furniture fitting and a piece of furniture with a corresponding drawer.

There are a variety of ways known in the art to attach a front panel to a drawer container, in particular to the drawer frame. It is important on the one hand, that the front panel is attached to the frame relatively easy and quickly detachable from the drawer. On the other hand, it is also important that adjustment are provided in order to adjust the front panel relative to the drawer frame at least in the vertical and lateral directions.

An example of such a drawer frame with a corresponding furniture fitting goes from the WO 2009/006651 in which in the drawer frame, a base plate and a mounting plate and a corresponding height adjustment and a support plate and a tilt adjustment device are provided. In contrast, a side adjustment is arranged on the mountable on the front panel connecting element. A disadvantage of this design is the relatively large footprint of the entire drawer. This means that the drawer frame is designed to be relatively wide (over 2 cm), especially in the lower area, thus reducing the volume available in the drawer (high space requirement). In addition, the locking mechanism as well as the individual adjustment mechanisms is very complex and designed with relatively many parts and therefore complicated.

In a similar way and with the same disadvantages goes from the EP 0 636 327 A1 a device for attaching the front panel of a drawer to drawer out. An eccentric serves to adjust the height of a receiving plate relative to a base plate. On this mounting plate a mounted on the front panel over dowel holding part is mounted, this hinged holding part can be adjusted laterally via a head of an adjusting screw. Thus, the eccentric engages the height adjustment on a different part than the head of the adjusting screw for lateral adjustment.

Furthermore, it is from the not pre-published, but priority senior applicant registration AT 509 411 a the preamble of the claim according to the invention forming drawer known. From this document is already a relatively narrow (less than 1 cm thick) drawer out, on which a front panel can be releasably locked. In this frame actuating elements for lateral and vertical adjustment of a control plate are provided in the fastening device for the front panel. At the same time, this positioning plate forms the connecting element that can be preassembled on the front panel and is also detached from the remaining drawer container when removing the front panel and thus from the individual adjusting elements.

The object of the present invention is to provide a comparison with the prior art improved furniture fitting. In particular, the space required for furniture fitting should be reduced, at the same time the functionality for lateral adjustment, height adjustment and locking should be integrated as compact as possible in this furniture fitting.

This object is achieved for a furniture fitting with the features of the preamble of claim 1, characterized in that the connecting element can be suspended on the adjusting plate and participates in the suspended state, the adjustment movements of the adjusting plate relative to the frame plate. In contrast to the third, Austrian, earlier priority font can be solved by the fastening device, the front panel together with connecting element, the set by the adjusting elements corresponding adjusting plate remains in the fixture and thus is ensured when re-attaching the front panel that the previously set position of the front panel when re-attaching is unchanged. Through this Design can also the drawer wall (thickness of the frame) to less than 15 mm, preferably to less than 11 mm or even to a maximum of 8 mm, be reduced. In addition, the two adjusting elements for the lateral and vertical adjustment of the fastening device are assigned, so that the front panel together with the connecting element can be made very simple. "Assigned to the front panel" means that the corresponding parts are located on the front panel in the event of a hung front panel. In contrast, "associated with the drawer frame" means that the corresponding parts remain arranged with the front panel removed on the drawer or on its fastening device.

According to a preferred embodiment of the present invention can be provided that the adjusting plate has at least one Einhängnut into which the connecting element via a, preferably pin-shaped, latching element can be suspended. This suspension groove preferably has vertically upwardly pointing side boundaries, so that when the front panel is attached the latching elements remain in the suspension groove by gravity.

Especially with high front panels (over 25 cm) may be preferably provided that the adjusting plate has two Einhängnuten, in which the connecting element via one, preferably pin-shaped, latching element can be suspended. The individual locking elements are arranged vertically one above the other. Of course, should not be ruled out that three or more locking elements are arranged one above the other on a one-piece or multi-part connecting element. It should also be noted that identical connecting elements are arranged on both side areas of a front panel, which correspond correspondingly to the two drawer side walls formed by the frames, wherein the frames preferably have mutually mirror-inverted fastening devices.

Preferably, the connecting element may be formed such that it has two mutually substantially parallel tabs, wherein between the tabs connecting the tabs, the latching element forming pin is arranged, via which the connecting element to the adjusting plate of the fastening device can be hung. Thus, the connecting element is preferably designed in the form of a slide-on rider.

In order to achieve the most accurate fitting of the connecting element to the fastening device (in particular at the groove of the adjusting plate), it can preferably be provided that the distance between the mutually substantially parallel tabs at least in the region of the detent element forming pin is 40% greater as the thickness of the actuator plate. By this slightly larger distance between the two tabs relative to the thickness of the adjusting plate, the connecting element can be hung relatively unhindered on the adjusting plate and it is still prevented too great play of the connecting element relative to the adjusting plate in the lateral direction. In addition, lateral adjustment is facilitated by the lateral play.

Alternatively, however, it can also be provided that the distance between the two tabs can also be much larger. It can then be provided that the rivet-shaped pin has a corresponding recess or notch, which is adapted to the thickness of the adjusting plate in the region of the groove, so that hardly any play between the locking element and the adjusting plate in the mounting position in the front panel.

In order to achieve a particularly stable formation of the connecting element, it can preferably be provided that the connecting element is U-shaped in cross-section, wherein the two mutually substantially parallel tabs are connected to one another via a pin remote crosspiece.

For a simple attachment and secure holding the front panel to the frame may preferably be provided that the fastening device comprises a locking device by which the hinged to the adjusting plate connecting element to the fastening device is releasably lockable. Preferably, the front panel can be attached without tools to the drawer, whereas when loosening the locking device, a tool (screwdriver or the like) should be used.

Furthermore, it can preferably be provided that the adjusting plate by a first adjusting element in the form of a lateral adjustment relative to the frame plate in Side direction is pivotable and is displaceable by a second actuator in the form of a height adjustment relative to the frame plate in the height direction. In this case, the lateral adjustment device is preferably designed in the form of a thread, wherein the adjusting plate engages in the region of the threads and can be pivoted laterally by turning. The height adjustment device is preferably designed in the form of an eccentric, which acts on the control plate and, depending on the position, shifts the control plate to different heights. Preferably, the axis of rotation of the two adjusting elements relative to the frame plate of the fastening device is fixed in position. In principle, however, should not be ruled out that the control elements are not rotatable but, for example, slidably actuated. In order to allow the adjustment at all, there is enough clearance between the first adjusting element and the adjusting plate in the vertical direction in order to allow an adjustment of the second adjusting element in the vertical direction. Accordingly, there is enough play between the second adjusting element and the adjusting plate in the lateral direction to permit an adjustment of the first adjusting element in the lateral direction.

It should not be ruled out that the control plate is designed in several parts, so that the actuating elements and a locking element provided engage different parts of the control plate. Preferably, however, it is provided that the adjusting plate is integrally formed and attack both adjusting elements of this one-piece actuator plate.

In order to move the adjusting plate within predetermined limits relative to the frame plate of the fastening device, it is preferably provided that the adjusting plate is non-detachably and movably connected to the frame plate via bearing elements. Particularly preferred in this regard is provided that the frame plate has two mutually substantially parallel and mutually fixed plate parts and the adjusting plate is disposed between these two plate parts, wherein the two plate parts and the adjusting plate are connected to each other via the bearing elements. In this case, bearing elements may be provided which connect only the two plate parts of the frame plate together. At the front panel facing away from the frame plate while two bearing elements should be provided, on which the actuator plate in the actuator plate formed elongated holes in the height direction displaceable and held in the assembled state inextricably between the plate parts of the frame plate.

Protection is also desired for a drawer with the features of claim 11 and for a piece of furniture with the features of claim 12.

Fig. 1 shows in a 3D view of the furniture 19, consisting of a furniture body 20 and a drawer 21 relative to the furniture body 20 movable drawer 16. This drawer 16 has a drawer bottom 17, a drawer rear wall 18, two drawer side walls forming drawer 3 and third 'and one with the drawer 3 and 3' connectable front panel 2.

Fig. 2 shows a two-part, preassembled on the front panel 2 connecting element prior to attachment to the drawer 3. In Fig. 3 the trained in the drawer frame fastening device 4 is shown, which forms the furniture fitting 1 with the first part 5a and the second part 5b of the connecting element 5. Here, these two parts 5a and 5b in the mounted state on the front panel 7a to each other on a fixed, non-adjustable positional relationship and are arranged in alignment with each other on the front panel 2. Preferably, these two parts 5a and 5b are formed substantially identical to each other.

In Fig. 4 the drawer 3 is shown attached to the front panel 2 position. This is fitting in Fig. 5 the furniture fitting 1 shown, the connecting elements 5a and 5b are connected to the fastening device 4 and are releasably locked by the locking device 14.

In Fig. 6 a furniture fitting 1 is shown, in which the connecting element 5 is attached to the fastening device 4. The fastening device 4 consists essentially of the two plate parts 6a and 6b of the frame plate 6, the adjusting plate 7, the two adjusting elements 8 and 9 and the locking device 14. The connecting element 5 has as essential components in the U-shaped base element and the locking elements 11 and 11 'and the mounting elements 23. These mounting elements 23 are preferably formed in the form of dowels and are used to mount the connecting element 5 on the front panel 2, wherein the Dowels are fixed by spreading 30 in appropriately formed in the front panel pilot holes.

In the exploded view according to Fig. 7 the five bearing points 27 formed on the plate part 6b are shown. The corresponding corresponding bearing points on the plate part 6a are also provided with the reference numeral 27. The two plate parts 6a and 6b of the frame plate 6 are fixedly connected to each other by the bearing elements 15 and 15 ', wherein in the connected state, the bearing elements 15' rest against the slots 22 of the control plate 7 as possible without play, so that the control plate 7 insoluble, but still in the vertical direction HR relative to the frame plate 6 is displaceable. These bearing elements 15 'may have a partially spherical area central region. The adjusting element 8 for adjustment in the lateral direction SR is rotatably mounted in the plate part 6b and engages via the thread 34 at an edge of the receiving opening 29 of the adjusting plate 7. By actuating (turning) the adjusting element 8 by a tool acting on the cross recess 33, the adjusting plate 7 is pivoted relative to the plate parts 6a and 6b, since the adjusting plate 7 is held centrally between the plate parts 6a and 6b by the bearing elements 15 'remote from the front panel. In this case, the bearing elements 15 'form, so to speak, the pivot axis for the adjusting plate 7. Furthermore, the adjusting element 9 for adjusting the position of the adjusting plate 7 in the height direction HR relative to the plate parts 6a and 6b is shown. This adjusting element 9 is rotatably mounted in the plate part 6b and has an eccentric bulge 35 (see in particular Fig. 8 ), wherein this rests on the edges of the receiving opening 28 in the adjusting plate 7 and by adjusting this adjusting element 9, a height adjustment of the adjusting plate 7 is achieved (for a more detailed illustration is exemplary of the Fig. 12 and 13 of the AT 509 411 note). The adjusting plate 7 is associated with a locking element 14, which is rotatably mounted on the rotary axle receiving 26 of the adjusting plate 7 via a rotation axis part 25, wherein this locking element 14 is acted upon by a force of a locking spring 24. Furthermore, in the Fig. 7 the Einhängnuten 10 and 10 'shown, where the connecting element 5 via the locking elements 11 and 11' can be suspended.

The 8 and 9 show a furniture fitting 1 for a low front panel 2, wherein the connecting element 5 has only one locking element 11 and accordingly also in the region of the fastening device 4, only one Einhängnut 10 is formed. In principle, it should not be ruled out that the connecting element 5 has more than the two mounting elements 23 shown, but is provided as a preferred ratio that per locking element 11 two, arranged at the same distance from the locking element 11 mounting elements 23 are provided.

In the 10 and 11 the position of the locking element 14 is shown prior to attachment of the connecting element 5, wherein the locking spring 24 is in (at least relatively) relaxed position. The slightly indented area 36 of the locking element 14, together with the groove-shaped indentation 32 in the adjusting plate 7, a guide for the first mounting of the connecting element 5 and the locking element 11. A corresponding "Voreinhängeposition" is suitable in Fig. 12 shown. In particular, this groove-shaped indentation 32 serves to prevent the shutter 2 from falling down during the unlocking of the connecting element 5 or the front panel 2 and that the unlocking is supported. In Fig. 12 is also clearly visible that the locking spring 24 rests on the one hand on the locking element 14 and on the other hand on the adjusting plate 7.

In Fig. 13 the connecting element 5 and its locking element when connecting or snapping on the fastening device 4 is shown, wherein the locking device 14 is rotated by moving the locking lug 31 to the left in the clockwise direction about the axis of the rotary axis part 25. During this movement, the spring 24 is tensioned. These Fig. 13 also shows a pre-locking in unfavorable tolerance position.

Fig. 14 shows the connecting element 5 and its locking element 11 in locked by the locking device 14 position, wherein the locking lug 31 is disposed above the locking element and thus removal of the front panel 2 is prevented. Only by pressing the Phillips 33 and pivoting the locking element 14 in the clockwise direction, the locking lug 31 moves to the left and thus releases the locking element 11. When the upper adjusting element 9 is actuated, the adjusting plate 7 moves upwards or downwards relative to the plate parts 6a and 6b in the height direction HR.

The Fig. 15 and 16 show a one-piece connecting element 5 with two locking elements 11 and 11 ', at the two Einhängnuten 10 and 10' of the Fastening device 4 are mounted. There is only one locking device 14 is necessary because the locking takes place in the region of the upper Einhängnut 10 'over the contour.

In the Fig. 17 and 18 is the lateral adjustment or Seitenverschwenkung the control plate 7 relative to the plate parts 6a and 6b of the frame plate 6 illustrates. By pressing or turning the adjusting element 8, the position of the thread 34 changes and the fitting in the thread of the thread adjusting plate 7 is pivoted accordingly, since it is held in the front panel remote area on the bearing element 15 'centrally between the plate parts 6 a and 6 b, causing the front panel-facing part of the adjusting plate 7 adjusted in the lateral direction SR.

In the FIGS. 19 and 20 It can be seen that the locking element 11 connects the two tabs 12 of the cross-sectionally U-shaped connecting element 5, wherein the tabs 12 are integrally connected by the transverse web 13. With only slight pivoting of the adjusting plate 7 is due to the game (about 2/10 mm) between the adjusting plate 7 and the tabs 12 of the connecting element 5 hardly any movement of the connecting element with the adjusting plate 7 and thus hardly given a lateral adjustment. The obliquely the adjusting plate 7 but adjusted, the more follows also the connecting element 5 of the inclination. By this Seitenverstellmechanismus a total lateral adjustment is given by about 1.5 mm. In Fig. 20 It can be seen that the distance A between the tabs 12 of the connecting element 5 by about 30% greater than the thickness D of the adjusting plate 7, whereby the hooking of the connecting element 5 is facilitated on the fastening device 4.
