Description

The invention relates to a drawer with side frames and a front panel which is adjustable laterally and / or in its height position, i.e. in the direction of its planar extent, and which is connected to the side frames via support elements which are displaceably guided in the side frames in the longitudinal direction of the side frames, wherein the support elements cooperate with clamping devices which are respectively arranged in the side frames and by means of which the front panel can be pulled in order to be fixed against head ends of the side frames, wherein the front panel is displaceable laterally in an adjustment position of the clamping device and / or in its height position relative to the side frame, and wherein in the adjustment position the front panel is spaced apart from the side frame and is adjustable in the direction of the side frame by pressure on the front panel. The invention further relates to a furniture fitting for fastening a front panel to side frames of a drawer, comprising a clamping device and a panel carrier interacting with the clamping device via a support element. The invention further relates to a method for adjusting a front panel of a drawer.In drawers or furniture fittings of this type, the front panel can be easily mounted on the one hand by inserting holders connected to the front panel into the clamping devices and by actuating the clamping devices pulling the front panel against the head ends of the side frame and thus fixing it. On the other hand, the front panels can be easily adjusted in the lateral direction (left / right) or with respect to the height (top / bottom) by bringing the front panel into the desired position in the relaxed state or in a slightly tensioned state and then fixing it by actuating the tensioning device. Displaceability of the front panel relative to the side frames results here either from displaceability of the holders relative to the front panel or from displaceability of the holders within their guides in the side frames. The holders can be fastened directly to the front panel or to a front panel carrier, to which the front panel is in turn fixed. Front panel attachments of this type for drawers are known, for example, from the publications DE 2 823 251 A1 or AT 390 872 B. In both cases, an eccentric rotary latch is used as the clamping element. The publication EP 0 732 069 A2 shows an adjustable front panel attachment for a drawer, wherein a toggle joint lever, which can be operated from the underside of the drawer, is used as a clamping device.The publication U.S. Pat. No. 5,375,923 A likewise describes a front panel fastening for drawers with an eccentric rotary latch as clamping device, by means of which the front panel can be used for fastening to side frames of the drawer. The rotary latch acts via a head of a tension bolt on a panel carrier which is connected to the front panel. In a relaxed position of the eccentric rotary latch, the panel carrier and thus the front panel can be displaced laterally and / or in terms of their height with respect to the tension bolt in order to adjust the front panel.The spread of increasingly wider drawers and the use of materials with a high density, for example stone or glass, in front panels gives rise to the problem that such front panels slide directly downward on release of the clamping device on account of the weight force. It is difficult or even impossible to set an adjustment position on the clamping device, in which the position of the front panel is still easily displaceable manually, but a set position is maintained independently until the clamping device is brought into the clamped position and the front panel locking position.It is an object of the present invention to provide a drawer with an adjustable front panel and a furniture fitting for adjusting a front panel of a drawer, in which an adjustment position of the clamping device is provided, in which the front panel can easily be displaced manually into a desired position, wherein this position is maintained even without the user acting against the weight force of the front panel.This object is achieved by a drawer or a furniture fitting having the features of the respective independent claim. Advantageous embodiments and developments are the subject matter of the dependent claims.In the drawer, an adjustment position of the clamping device is provided, in which the front panel is displaceable laterally and / or in its height position relative to the side frame. In the adjustment position, the front panel is spaced apart from the side frame, wherein the front panel is adjustable by pressure on the front panel in the direction of the side frame.The front panel is thus adjustable and only when it is pressed in in the direction of the side frame, which is achieved only by the spacing from the side frame in the adjustment position. Without the user acting, the front panel remains in its position.According to the invention, a force storage device is provided in the releasable holding device for this purpose, by means of which the front panel is fixed in its position relative to the side frame in the adjustment position by static friction and / or a latching. Preferably, the front panel or alternatively a panel carrier carrying the front panel has a latching field with which a latching element of the carrying element interacts. A spring can be used as a force accumulator, which is arranged between the front panel or the panel carrier and the support element. In a particularly compact design, such a panel carrier is pot-shaped and can be inserted into the front panel, wherein the energy store is integrated into the panel carrier.In an advantageous embodiment of the drawer, the releasable holding device fixes the front panel laterally and / or with respect to its height position in the adjustment position and releases it for adjustment by pressure on the front panel in the direction of the side frame. The front panel can be adjusted in this way while the drawer is retracted. In this position, the gap dimension to adjacent furniture fronts can advantageously be used as an adjustment aid.In a further advantageous embodiment of the drawer, the clamping device has an eccentrically running clamping curve with which the support element interacts. Alternatively, the clamping device has an arrangement of levers connected to one another, with which the supporting element interacts. Both embodiments are suitable both for providing the clamping functionality and for bringing the front panel into the required adjustment position. In a tensioned position, the tensioning device brings the adjustable front panel into contact with the side frame in such a way that the support element and the front panel cannot be displaced relative to one another.A furniture fitting according to the invention of the type mentioned at the beginning is characterized in that in an adjustment position of the clamping device the panel carrier is laterally and / or in its height displaceable with respect to the support element, wherein a force accumulator acting on the support element is provided, by means of which the panel carrier interacts with the support element in such a way that the panel carrier is fixed in its position relative to the support element, and wherein the interaction of support element and panel carrier is canceled by pressure on the front panel in the direction of the side frame, whereby the front panel is adjustable on all sides. The advantages mentioned in connection with the drawer result.Finally, a method according to the invention for adjusting a front panel of a drawer has the following steps: an adjustment position is set, in which the front panel is spaced apart from a side frame of the drawer, wherein a releasable holding device fixes the front panel laterally and / or in its height position in this adjustment position. The releasable holding device is then released by pressing the front panel in the direction of the side frame and the lateral and / or height position of the front panel is manually adjusted. After the front panel is relieved of the pressure in the direction of the side frame, a clamping device is actuated, as a result of which the front panel is pulled against a head end of the side frame in order to be fixed. The aforementioned advantages also result here: the front panel can be adjusted manually and, due to the releasable holding device, nevertheless maintains its position when it is released by the user after the adjustment.The invention is explained in more detail below with reference to exemplary embodiments with the aid of figures. The figures show: FIG. 1 a shows a detail of a drawer with a fitting for adjustably fastening a front panel in a first exemplary embodiment in a sectional illustration in a locking position; FIGS. 1 b, 1 c show the drawer of FIG. 1 a in an adjustment position and during an adjustment of the front panel; FIG. 2 ashows a second exemplary embodiment of a drawer with a fitting for adjusting the front panel on all sides in a second exemplary embodiment in a sectional illustration in a locked position, and FIGS. 2 b, 2 c show the drawer of FIG. 2 a in an adjustment position and during an adjustment of the front panel.FIGS. 1a to 1c show a first embodiment of a drawer with a fitting for adjusting a front panel. The figures are sectional representations through the front part of the drawer, wherein the section is carried out perpendicularly along the direction of the longitudinal extent of the side frame. FIG. 1 ashows the drawer with a fixed and locked front panel. FIG. 1 bshows the front panel in an adjustment position, in which it can be adjusted by a user in the lateral direction and / or with respect to its height. FIG. 1 c finally shows the adjustment process.The drawer shown in FIG. 1a has side frames 1, against the top end 2 of which a front panel 5 bears. The front panel 5 is configured in a planar manner with a front 6, which points away from the side frames 1, and a rear 7, which abuts the head ends 2 of the side frame 1. Usually, two side frames 1 are provided on the right and left sides of the drawer, respectively. For the sake of simpler illustration, only the one side frame 1, visible here in FIG. 1, is mentioned in the following.For connecting the front panel 5 to the side frame 1, the front panel 5 is connected to a panel carrier 30.In the exemplary embodiment shown, the panel support 30 is of pot-shaped construction and is inserted into a corresponding pot hole bore 8 which is made in the front panel 5 from the rear side 7. For this purpose, the diaphragm carrier 30 has an external catch 31, with which it is fixed in the pot hole bore 8, optionally in conjunction with an adhesive, screws or another conventional pot connection method. The panel support 30 has a base 32 which extends outwards flush with the rear side 7 of the front panel 5. In the middle of the bottom 32 there is a central bore 33 through which a support element 20 with its shaft 21 leads. The shaft 21 of the support element 20 thus protrudes substantially perpendicularly from the rear side 7 of the front panel 5. In the interior of the diaphragm carrier 30, the shaft 21 is connected to a plate 24 running perpendicular to it. On its side pointing toward the frame, the plate 24 has latching projections 26, with which it rests on the inner side of the base 32 of the panel carrier 30. On this inner side, the bottom 32 is provided with a latching field 34, which enables latching in both spatial directions, i.e. for example upwards and downwards in the drawing plane and into and out of the drawing plane. At the edge opposite the base 32, the panel support 30 is substantially open, but is provided with a circumferential, inwardly pointing clamping edge 35. A spring 36 is inserted on this clamping edge 35, which is designed here as a plate or leaf spring. The spring 36 presses in its central region onto a head surface 25 of the plate 24.At its end opposite the plate 24, the shank 21 initially merges into a taper 22, at the end of which a head 23 is arranged. Preferably, the support element 20 is manufactured in one piece. Alternatively, it is also conceivable for the shaft 21 to be produced integrally with the plate 24, for example as a plastic injection-molded part. The taper 22 with the head 23 is inserted into the latter, wherein the taper 22 and the head 23 are in turn formed in one piece, for example as a metal formed part. In this case, provision can be made for the taper 22 to be provided with an external thread and the shank 21 to be provided with an internal thread, with the result that the length of the supporting element 20 from the plate 24 to the head 23 can be adjusted.In the side frame 1 a clamping device 10 is arranged which interacts with the support element 20. In the present exemplary embodiment, the clamping device 10 is an insert which can be rotated within the side frame 1 and has a substantially circular outer contour. With this outer contour, the clamping device 10 is inserted into a corresponding circular receptacle 3 in the side frame 1. On the outer contour, the clamping device 10 has a grid 11 which prevents an undesired rotation of the clamping device 10. The clamping device 10 is of sickle-shaped construction, one side of the sickle providing an eccentrically running clamping cam 12. On the other side of the sickle, a substantially hook-shaped recess is formed, which will be referred to below as the adjustment position 13. From the receptacle 3 for the clamping device 10, a guide 4 runs through the side frame 1 toward the front panel 5.By means of this guide 4, the shank 21 of the support element 20 is guided in a sliding manner and in a displaceable manner in the longitudinal direction of the side frame 1. The head 23 of the support element 20 projects into the clamping device and rests on the clamping cam 12. In this position, a tensile stress can be exerted on the support element 20 by rotating the clamping device 10. This tension, on the one hand, presses the plates 24 with their latching projections 26 onto the latching field 34 of the base 32 of the panel carrier and thus fixes the supporting element 20 relative to the panel carrier 30 in such a way that a displacement of the two elements relative to one another is not possible. At the same time, the panel support 30 and thus the front panel 5 are pulled against the head end 2 of the side frame 1 and thus fixed in a force-locking manner. For actuating the clamping device 10, a tool holder, which is not visible in this figure, for example for a screwdriver or for a socket wrench, is provided on the clamping device 10.If the clamping device 10 is now rotated in the clockwise direction, the tension of the support element 20, with which the support element 20 pulls the front panel against the side frame 1, is first reduced. Upon further rotation, the head 23 is brought out of engagement with the clamping cam 12. Upon further rotation, the head 23 is fixed in the adjustment position 13, as is shown in FIG. 1 b. The adjustment position 13 is arranged within the clamping device 10 such that the front panel 5 is spaced apart from the head end 2 of the side frame 1. Due to the spring 36, however, the plate 24 is still pressed with its latching projections 26 against the latching field 34. The panel support 30 and thus the front panel 5 thus maintains its lateral or height position relative to the support element 20.The front panel 5 can thus be brought from the locked position into the adjustment position 13 without its lateral or height position changing. If a pressure is now exerted by the user on the front surface 6 of the front panel 5 in the direction of the side frame, the latching projection 26 and the latching field 34 can be disengaged counter to the spring force of the spring 36. This state is shown in FIG. 1c. In this state, the front panel 5 can be adjusted laterally and / or in its height position freely within its displacement range. This is defined by the size of the plate 24 in relation to the inner diameter of the aperture carrier 30 or by the size of the central bore 33 relative to the shaft 21. The front panel 5 can thus be adjusted with the drawer closed until a desired position is reached, in which, for example, a uniform gap dimension with respect to adjacent elements of the furniture front is achieved. When the pressure is removed from the front surface 6 after adjustment has been completed, the latching projections 26 again engage with the latching field 34 by the spring 36, so that the set desired position is maintained. Subsequently, by rotating the clamping device 10 in the counterclockwise direction, the front panel 5 can first be pulled to the head end of the side frame 1 and then pressed against the latter.FIG. 2 shows in three different sectional views, analogously to FIG. 1, a further exemplary embodiment of a drawer with side frames and an adjustable front panel. Identical reference numerals in this exemplary embodiment identify identical or identically acting elements as in the first exemplary embodiment.Again, in this exemplary embodiment, a clamping device 10 is also provided in the side frame 1, with which a panel carrier 30, on which the front panel 5 is fixed, can be pulled in the direction of the side frame, so that the front panel 5 is clamped against head ends 2 of the side frame 1 and is thus fixed with respect to its side and / or height position. In contrast to the exemplary embodiment of FIG. 1, the clamping device 10 in this exemplary embodiment uses a clamping mechanism which has a plurality of articulated and interconnected levers 14 and a tension spring 17. Two actuating levers are provided, a positioning lever 15 and an unlocking lever 16, which cooperate with the levers 14 in such a way that a supporting element 20 connected to the front panel 5 can be inserted in a longitudinal direction of the side frame 1, is gripped and is tightened by the tension spring 17 under the action of spring force. With the disengagement lever 16, the support element 20 can be released in order to be able to remove the front panel 5 again. With the aid of the positioning lever 15, the entire clamping mechanism can be moved in such a way that the front panel 5 can be spaced apart from the side frame 1 and is thus in the adjustment position.A further difference from the first exemplary embodiment is the configuration of the supporting element 20, which here has a flat, tab-shaped shaft 21 which is provided with a guide slot 27.The basic mode of operation in this exemplary embodiment corresponds to that of FIG. 1. By inserting the supporting element 20 into the clamping device 10, an inserted front panel can be pulled via the supporting element 20 against the head end 2 of the side frame 1. Here, the plate 24 connected to the shaft 21 again abuts a base 32 of the panel carrier 30, wherein both the plate 24 and the base 32 have latching means, for example the latching projections or latching surfaces mentioned in connection with the first exemplary embodiment, which engage in one another. After actuation of the positioning lever 15, the clamping device 10 with the support element 20 is extended in the locked state, so that the front panel 5 is spaced apart from the head end 2 of the side frame 1. This is shown in FIG. 2 b. Due to the spring 36, which is designed as a spiral spring in the present case, the plate 24 of the support element 20 and the latching surface of the base 32 are still pressed against one another, as a result of which the position of the panel support 30 relative to the support element 20 and thus the position of the front panel 5 do not change.As shown in FIG. 2 c, the spring 36 can be compressed by pressure on the front surface 6 of the front panel 5, whereby the plate 26 with its latching means is spaced apart from the latching surface of the base 32. In this state, the front panel 5 can be brought into the desired position laterally and in its height. Subsequently, by actuating the positioning lever 15 and the clamping lever 16, the locked state shown in FIG. 2 acan be reached again.List of reference characters1 Side frame 2 Head end 3 Receptacle for clamping device 4 Guide 5 Front panel 6 Front 7 Rear side 8 Pot hole bore 10 Clamping device 11 Grid 12 Clamping curve 13 Adjustment position 14 Lever 15 Positioning lever 16 Unlocking lever 17 Tension spring 20 Supporting element 21 Shaft 22 Taper 23 Head 24 Plate 25 Head surface 26 Latching projection 27 Guide 30 Panel carrier 31 External latching 32 Base 33 Central bore 34 Latching field 35 Clamping edge 36 Spring
