Description

Field of the Invention

[0001] The invention relates to an adjustment device for a furniture drawer, in particular a drawer, the furniture drawer having a front element extending in the width direction of the furniture drawer, a rear wall arranged opposite the front element, and at least two side parts extending between the front element and the rear wall, wherein the furniture drawer is guided movably relative to a furniture body by means of at least one guide unit belonging to the adjustment device, wherein the guide unit has a main rail fixable to the furniture body and at least one pull-out rail movably supported relative to the main rail and coupled to the furniture drawer by means of at least one coupling unit, and wherein the adjustment device has at least one adjustment unit for adjusting the relative position between the furniture drawer and the pull-out rail. Background Art

[0002] Adjustment devices for furniture drawers have long been known, which are used to adjust or align the position of the furniture drawer relative to the furniture body surrounding it.

[0003] As a popular example, mention is made here of an adjustment device with which the engagement diagram between the front element of a drawer and the furniture body surrounding the front element can be adjusted.

[0004] Such an adjustment device is described, for example, in DE 20 2015 006 934 U1, wherein the adjustment device includes a so-called latch coupler which is used to couple the drawer and the assigned pull-out rail of the guide unit. The latch coupler has a lateral adjustment unit with which the relative position of the front element relative to the furniture body in the width direction can be adjusted. If necessary, the latch coupler is also configured as a so-called 3D latch coupler, so that relative position adjustment can also be carried out along two other spatial directions, namely the depth direction and the height direction.

[0005] However, when using such an adjustment device, it may occur that during maximum lateral adjustment of the furniture drawer, the adjustment stroke is so large that the furniture drawer tilts in the front-to-back situation. As a result, a front gap or closing error may occur between the front of the drawer or the front element and the front edge of the body. Summary of the Invention

[0006] The object of the invention is to provide an adjustment device of the type mentioned at the beginning, with which the relative position between the furniture drawer and the furniture body surrounding the furniture drawer can be optimally adjusted, wherein the adjustment device can in particular adjust a front gap which is particularly evenly constructed between the front element of the furniture drawer and the surrounding furniture body.

[0007] This task is solved by an adjustment device having the features of independent claim 1. The expansion solutions of the present invention are described in the dependent claims.

[0008] The adjustment device according to the invention is characterized in that the adjustment unit is assigned to the rear end of the pull-out rail and has a base body that can be fixed to the furniture pull-out side. The actuating element and the actuator are movably supported on the base body such that the actuator can be adjusted relative to the base body by actuating the actuating element in order to adjust the relative position between the furniture pull-out and the pull-out rail in the region of the rear end of the pull-out rail in the width direction.

[0009] In order to achieve, in the front visible region as described above, a uniform joint pattern or a uniformly structured front gap between, on the one hand, the furniture pull-out and, on the other hand, the furniture body surrounding the furniture pull-out, the relative position between the furniture pull-out and the pull-out rail is adjusted in the rear region of the pull-out rail or in the region of the rear end.

[0010] It is possible that such an adjustment device is only assigned to the rear end of the pull-out rail and thus the adjustment is only carried out in the region of the rear end of the pull-out rail. However, it is advantageous, especially in order to avoid the disadvantages of the front-to-back side skew position described above for the furniture pull-out, that in addition to the adjustment unit in the region of the rear end of the pull-out rail, an adjustment unit is also provided in the front region of the pull-out rail.

[0011] Therefore, it is particularly preferred that the adjustment device has at least one alignment unit assigned to the front region of the pull-out rail, which alignment unit is used to adjust the relative position between the furniture pull-out and the pull-out rail in the region of the front end of the pull-out rail in the width direction.

[0012] In a particularly preferred manner, the alignment unit is part of a coupling unit, for example, it can be integrated into the coupling unit. It is possible that with the aid of the alignment unit, so-called 3D adjustment can be carried out in all three spatial directions, that is to say, the adjustment of the relative position of the furniture pull-out with respect to the furniture body can be carried out in the width direction, height direction and depth direction.

[0013] In an extended embodiment of the present invention, the coupling unit is configured as a locking coupler for releasably locking the pull-out rail and the furniture pull-out part. Since the furniture pull-out part is usually guided relative to the furniture body by two opposed guide units, namely a right guide unit and a left guide unit, it is expedient to assign an adjustment unit to each pull-out rail, i.e., the left pull-out rail and the right pull-out rail, respectively, at the rear end of the respective pull-out rail, which adjustment unit is used to adjust the relative position between the furniture pull-out part and the pull-out rail. However, in principle, it is also conceivable to provide an adjustment unit only on one of the pull-out rails at the rear end.

[0014] In an extended embodiment of the present invention, a coupling mechanism is provided which, in addition to the coupling unit, is assigned to the rear region of the pull-out rail and which has a coupling tab, in particular configured in the form of a hook, and a tab receiving part for receiving the coupling tab, the coupling tab and the tab receiving part being configured such that the clear width of the tab receiving part is so much greater than the width of the coupling tab that width compensation can be carried out.

[0015] It is expedient for the coupling tab to be configured, in particular, on the upper side of the pull-out rail and the tab receiving part to be configured on the side of the furniture pull-out part. However, in principle, it is also conceivable to assign the coupling tab to the furniture pull-out part and the tab receiving part to the pull-out rail.

[0016] In an extended embodiment of the present invention, a rear wall retainer is provided for connecting the assigned side member to the rear wall of the furniture pull-out part. The side member can be configured as a side wall or, as an alternative, as a side frame, the latter usually being configured as a cavity-frame.

[0017] In a particularly preferred manner, the rear wall retainer has a fixed interface on which the adjustment unit can be fixed or to which it can be fixed.

[0018] Particularly preferably, the rear wall retainer is configured as an angle profile which has a first profile leg assigned to the side member and fixable there and a second profile leg assigned to the rear wall and fixable there, with the fixed interface preferably being configured for fixing the adjustment unit to the second profile leg.

[0019] In an extended embodiment of the present invention, the base body and / or the actuator are configured in a plate-like manner.

[0020] In a particularly preferred manner, the actuator is rotatably supported on the base body by means of a swivel bearing device, wherein the rotary movement of the actuator can be triggered by the actuation of a control element. However, as an alternative, it is also conceivable that the actuator can move linearly relative to the base body by means of a suitable bearing device, wherein the linear movement of the actuator can also be triggered by the actuation of a control element.

[0021] In an extended embodiment of the present invention, the actuating element is configured as an adjusting wheel, which is rotatably arranged on the base body, wherein the rotational movement of the adjusting wheel can be converted into a rotary movement of the actuating mechanism by a conversion device acting between the adjusting wheel and the actuating mechanism. In the case of a linearly movable actuating mechanism, the rotational movement of the adjusting wheel can be converted into a linear movement of the actuating mechanism by a corresponding conversion device.

[0022] In an extended embodiment of the present invention, the conversion device has a worm guide portion, which has a worm groove and a guide journal that is inserted into the worm groove and is forcibly guided therein, wherein preferably the worm groove is formed on the adjusting wheel and the guide journal is formed on the actuating mechanism. As an alternative, it is possible to form the guide journal on the adjusting wheel and the worm groove on the actuating mechanism.

[0023] In an extended embodiment of the present invention, the actuating mechanism has a component for clamping the tension rail, in particular a clamping section of a hook, which can move for the purpose of width compensation in an adjustment movement of the actuating mechanism, which is triggered in particular by deflection, relative to the assigned component of the tension rail.

[0024] In an extended embodiment of the present invention, the fixing of the adjusting unit on the fixed interface of the rear wall holder is implemented by a fixing tab and a corresponding fixing slot for receiving the fixing tab, wherein preferably the fixing tab is formed on the rear wall holder and the fixing slot is formed on the base body. As an alternative, it is possible that the fixing tab is formed on the base body and the fixing slot is formed on the rear wall holder.

[0025] In a particularly preferred manner, the adjusting unit is made of plastic or made of a metallic material, such as steel or a metal casting material, preferably cast zinc.

[0026] The present invention further includes a piece of furniture, which has a furniture drawer that is movably guided relative to the furniture body by a guiding unit, and the furniture drawer is characterized by the adjusting device according to any one of claims 1 to 15.

[0037] Figures 1 to 9 Shows a preferred embodiment of the adjustment device 13 according to the invention in a furniture 11 equipped with a furniture drawer 12 in the form of a drawer.

[0038] As particularly shown in Figure 1 the furniture 11 has a furniture body 14 in which a drawer compartment 15 is constructed in the example case shown. The furniture drawer 12 is movably guided in the drawer compartment 15 and is constructed as a drawer in the example case shown.

[0039] The furniture drawer 12 in the form of a drawer has a bottom element 16, a front element (not shown), a rear wall 17 and two side parts 18a, 18b. The side parts 18a, 18b are constructed as side frames in the example case shown, suitably constructed as cavity-side frames.

[0040] As shown especially in Figure 1 shown, the rear wall 17 and the side members 18a, 18b project substantially vertically from the bottom element 16 and extend along the height direction 19. The rear wall 17 is opposite to the front element. The front element and the rear wall 17 extend along the width direction 20 of the furniture drawer 12. The two side members 18a, 18b form the left and right side end members of the furniture drawer 12 and extend along the depth direction 21, so that they are oriented substantially perpendicular to the rear wall 17 and the front element. At the mutually opposite inner sides 22a, 22b of the side walls 23a, 23b that define the furniture drawer 15 on the left and right in the furniture body 14, guide units 24a, 24b for guiding the assigned furniture drawer 12 are respectively fixed.

[0041] The guide units 24a, 24b are constructed substantially identically to each other, so that the description of the guide unit 24a also applies to the other guide unit 24b.

[0042] The guide units 24a, 24b each have a main rail 25, which can be configured, for example, as a bent plate member.

[0043] As shown especially in Figure 2 shown, the main rail 25 has main corner blocks for fixing, which have at least one mounting leg 26, and the mounting leg has a plurality of fixing openings (not shown) arranged, for example, in series one after another, through which the main corner blocks can be fixedly positioned on the assigned side wall 23a with the aid of suitable fixing devices. In the case of being oriented perpendicular to the mounting leg 26 and being assigned to the bottom of the drawer 15, the guide leg 27 extends along the depth direction 21 of the drawer 15.

[0044] In the illustrated exemplary case, the guide units 24a, 24b are configured as so-called full-extension drawers, which are characterized in that an intermediate rail 28 guided relative to the main rail 25 by a guiding device is assigned to the main rail 25.

[0045] Another component of the corresponding guide units 24a, 24b is a pull-out rail 29, which can also be referred to as a drawer rail. The pull-out rail 29 is connected to the furniture drawer 12 on the one hand by a coupling unit (not shown) and is guided relative to the intermediate rail 28 on the other hand.

[0046] Coupling units not shown in the drawings, for example, can be configured as so-called snap couplings, by means of which a releasable snap connection of the pull-out rail 29 and the furniture pull-out part 12 can be implemented. The snap coupling can be fixed to the lower side of the bottom element 16 and designed in such a way that it can be easily snapped into the snap coupling at the snap interface provided for this purpose on the pull-out rail 29.

[0047] A main aspect of the invention is the aforementioned adjustment device 13, which has at least one adjustment unit 30 for adjusting the relative position between the furniture pull-out part 12 and the pull-out rail 29.

[0048] In the illustrated exemplary case, the adjustment device 13 has two adjustment units 30a, 30b that are basically constructed identically to each other, where one of the adjustment units 30a is assigned to the left guiding unit 24a and the other adjustment unit 30b is assigned to the right guiding unit 24b. Therefore, the description of the operating principle of the adjustment units 30a, 30b below is limited to the explanation of the left adjustment unit 30a shown in Figures 2 to 4 where the right adjustment unit 30b has the same operating principle. In principle, it is possible that the adjustment device 13 has only a single adjustment unit, which is then either placed on the left guiding unit 24a or on the right guiding unit 24b. However, it is preferred to provide two adjustment units 30a, 30b.

[0049] As shown especially in Figures 1 to 4 the adjustment units 30a, 30b are each assigned to the rear end of the associated pull-out rail 29 and each have a base body 31 that can be fixed to the furniture pull-out part side. The actuating element 32 and the actuating mechanism 33 are supported on the base body 31 in such a movable manner that the actuating mechanism 33 can be adjusted relative to the base body 32 by actuating the actuating element 32 in order to adjust the relative position between the furniture pull-out part 12 and the pull-out rail 29 in the region of the rear end 34 of the pull-out rail 29 along the width direction 20.

[0050] As already mentioned, the furniture pull-out part 12 is coupled to the pull-out rail 29, especially in the region of the front end of the pull-out rail, by a coupling unit, especially in the form of a snap coupling. However, there is also a coupling between the furniture pull-out part 12 and the pull-out rail 29 in the region of the rear end 34 of the pull-out rail 29.

[0051] The coupling at the rear end 34 of the pull-out rail 29 takes place in a different way compared to the coupling unit.

[0052] Here, a coupling mechanism 35 is provided, which has coupling tabs 36 configured especially in the form of hooks. Further, a tab receiving portion 37 for receiving the coupling tabs 36 is provided, and the tab receiving portion is configured such that the net width of the tab receiving portion 37 is so much greater than the width of the coupling tabs 36 that width compensation can be carried out along the width direction 20. That is to say, the arrangement of the coupling tabs 36 and the tab receiving portion 37 allows relative movement of the furniture extension part 12 along the width direction 20 with respect to each other.

[0053] Suitably, the extension rail 29, as well as the intermediate rail 28 and the main body rail 25, are made of a metallic material, especially steel. Suitably, the coupling tabs are arranged on the extension rail 29, especially integrally formed therewith. In the case where the extension rail 29 is made of a metal, especially a steel material, the coupling tabs can be configured as bent tabs designed by an upward and forward bending of a part of the extension rail 29. Suitably, the tab receiving portion is on the side of the furniture extension part 12. Although not shown, the coupling tabs 36 have grooves, which have groove peaks and groove valleys placed successively along the depth direction. The groove valleys and groove peaks extend along the width direction 20. Paired grooves are formed on the tab receiving portion 37, whereby a stop along the depth direction 21 is carried out by the groove peaks on the coupling tabs 36 being embedded into the groove valleys of the paired grooves with respect to each other, that is to say, relative movement between the furniture extension part 12 and the extension rail 29 along the depth direction 21 is thereby prevented.

[0054] Although not necessary, but preferably, an adjusting unit (not shown) assigned to the front region of the extension rail 29 is provided for adjusting the relative position between the furniture extension part 12 and the extension rail 29 in the region of the front end of the extension rail 29 along the width direction 20. Suitably, the adjusting unit is part of a coupling unit in the form of a snap coupler.

[0055] As especially shown in Figures 2 to 4 a rear wall holder 38 is provided for connecting the assigned side member 18a to the rear wall 17 of the furniture extension part 12. In the shown example case, the left side member 18a is connected to the rear wall 17 by the rear wall holder 38. The rear wall holder 38 is configured as an angle profile.

[0056] As especially shown in Figures 2 to 4 the angle profile has a first profile leg 39a assigned to the side member 18a and fixable there, and a second profile leg 39b assigned to the rear wall 17 and fixable there. As for example in Figure 2As shown, the second profile leg 39b assigned to the rear wall 17 is fixed to the assigned rear wall 17 by means of fixing devices, such as fixing bolts 40. The second profile leg 39b assigned to the rear wall 17 has an inner side (not shown) that abuts against the outer side of the rear wall 17 in the installed state and an outer side 41 opposite to the inner side.

[0057] The rear wall holder 38 has a fixing interface 42 to which the adjusting unit 30a is fixed. In the example case shown, the fixing interface 42 is on the outer side 41 of the second profile leg 39b assigned to the rear wall 17.

[0058] Figures 5 to 9 The adjusting units 30a, 30b are shown, where the left adjusting unit 30a assigned to the left tension rail 29 is shown in the figure. The geometric shape that does not need to be mirror-formed relative to the left adjusting unit 30a, and the structure and principle of action of the unshown right adjusting unit 30b are the same.

[0059] The adjusting unit 30a basically has three main components. These are the base body 31, the operating element 32, and the actuator 33.

[0060] As especially shown in Figure 8 and 9 shown, the base body 31 and the actuator 33 are basically plate-shaped. As, for example, shown in Figure 2 shown, a tab receiving portion 37 that cooperates with a coupling tab 36 arranged on the tension rail 29 is on the second profile leg 39b of the lower side assigned to the rear wall 17.

[0061] The adjusting unit 30a is made of plastic in the example case shown, that is, the base body 31, the operating element 32, and the actuator 33 are suitably plastic bodies. It is particularly preferred that these plastic bodies are manufactured by plastic injection molding, whereby functional sections can be molded onto the base body 31 and the actuator 33 during manufacturing. Of course, it is also possible to manufacture the adjusting unit 30a from a metallic material.

[0062] The base body 31 of the adjusting unit 30a has an inner side 43 facing the actuator 33 and the second profile leg 39b of the rear wall holder 38 and an outer side 44 facing away from the inner side 43. The base body is penetrated by a plurality of fixing slots 45 extending between the inner side and the outer side 44, and the fixing slots are used to fix the adjusting unit 30a to the fixing interface 42. In order to fix the adjusting units 30a, 30b to the rear wall holder 38, fixing tabs 75 constructed on the second profile leg 39b are inserted into the fixing slots 45.

[0063] As, for example, shown in Figure 8As shown in FIG, the base body 31 is essentially rectangular, with the base body 31 having an upper edge 46 and a lower edge 47 arranged opposite the upper edge. In the region of the lower edge 47 of the base body 31, a cutout 48 is provided, into which the functional section of the actuator 33, which will be shown in more detail below, is arranged when the adjustment units 30a, 30b are installed. In the case of the left adjustment unit 30a, a projection 49 is placed to the left of the cutout 48, through which one of the fixing slots 45 extends.

[0064] As especially in Figure 9 As shown in FIG, the base body 31 has an upper edge wall section 50 formed on the upper edge 46 and pointing inwardly in the direction of the actuator. Between the upper edge 46 and the lower edge 47 of the base body 31 extend side edges 51 oriented perpendicular thereto, one of the side edges having a side edge wall section 52 which, in the installed state, surrounds on the outside the inner (right) side edge of the second profile leg 39a of the rear wall holder 38, which is associated with the rear wall 17.

[0065] As already mentioned, the actuator 33 is rotatably supported on the base body 31 by means of a swivel bearing arrangement, wherein a swivel movement of the actuator 33 can be initiated or triggered by actuating the actuating element 32 .

[0066] As especially in Figure 8 As shown in FIG, a main journal 53, which is rotatably mounted in an associated journal receptacle 54, is included in the slewing bearing element. In the exemplary case shown, the journal receptacle 54 is formed on the base body, while the main journal 53 is arranged on the actuator 33. The journal receptacle 54 is expediently located in the region of the upper edge 46 of the base body 31, and the main journal 53 is correspondingly located in the region of the upper edge 55 of the actuator 33. The arrangement of the main journal and the journal receptacles 53, 54 makes it possible to slew the actuator 33 relative to the base body 31 about an axis of rotation 56 oriented axially relative to the main journal 53.

[0067] The actuating element 32, which is already mentioned and is designed as an adjusting wheel in the example shown, serves to initiate a pivoting movement. Figure 5 As shown in FIG, the adjusting wheel protrudes laterally with a circumferential region beyond the left side edge 51 of the base body 31, thereby enabling the user to more easily manipulate the adjusting wheel from the outer side of the base body 31. Figure 9 As shown in FIG, the adjusting wheel is rotatably arranged on the base body 31. The rotational movement of the adjusting wheel is converted into a rotary movement of the actuator 33 by a conversion device acting between the adjusting wheel and the actuator 33.

[0068] As especially inFigure 9 As shown, another main journal 57 is constructed on the inner side of the base body, and an adjusting wheel is plugged onto the other main journal with a central bearing hole 58 and is rotatably supported there.

[0069] As particularly Figure 8 and 9 As shown in the overview of, the conversion device is constructed as a worm guide part 59, which has a worm groove 60 and a guide journal 61 that is immersed in the worm groove 60 and is forcibly guided there.

[0070] In the shown exemplary case, the eccentrically extending worm groove 60 is located on the adjusting wheel, where the guide journal 61 ( Figure 8 ) rests on the actuator 33. The guide journal 61 is arranged in the region of the side edge of the actuator 33. The guide journal 61 is immersed in the worm groove 60 constructed on the adjusting wheel in the installed state.

[0071] By introducing a rotational movement onto the adjusting wheel, the guide journal is forcibly guided in the worm groove 60 and slides inside the worm groove 60, whereby a rotational movement of the actuator 33 relative to the base body 31 occurs due to its eccentricity.

[0072] The base body 31 and the actuator 33 have additional functional sections. As particularly in Figure 8 As shown, a window-shaped void 62 is constructed on the base body, and behind this void, a partition-shaped coupling element 63 pointing towards the actuator 33 is constructed on the inner side 43 of the base body 31. Above and below the window-shaped void 62, fixing slots 45 are respectively present on the base body 31.

[0073] Particularly in Figure 8 and 9 The actuator 33 shown in and is constructed in a plate-like manner as mentioned. The actuator has an actuator-inner side 64 facing the base section and an actuator-outer side 65 that is assigned to the fixed interface 42 on the rear wall holder in the installed state of the adjusting unit 30a.

[0074] As already mentioned, the actuator 33 has an actuator-upper edge 55 and an actuator-lower edge 66 arranged opposite to the actuator-upper edge. As particularly in Figure 8 As shown, the actuator 33 has a clamping section 67 in the region of its lower edge 66, which is used to clamp components of the tension rail, that is, particularly hooks.

[0075] As particularly in Figure 8As shown, the clamping section has two clamping legs 68a, 68b opposite each other, which should be positioned at different positions relative to the coupling tab 36 or the hook of the tension rail as will be described in more detail below.

[0076] As especially shown in Figure 9 the actuator 33 has a window-shaped gap 69 into which the coupling element 36 on the base body 31 engages. The actuator 33 has actuator-side edges, with the left actuator-side edge wall section 70 in the mounted state on the left clamping profile leg 39a.

[0077] Figures 2 to 4 The operating principle of the adjusting device 13 according to the invention is shown.

[0078] In Figure 2 the initial position of the adjusting mechanism 30a is shown, in which the two clamping legs 68a, 68b are centered relative to the coupling tab 36 on the tension rail 29.

[0079] To perform width compensation in the region of the rear end of the tension rail 29, a rotational movement is induced by the adjusting wheel, which causes the deflection of the actuator 33. Here, the clamping section 67 with its two clamping legs 68a, 68b moves relative to the coupling tab 36, as for example shown in Figure 3 According to Figure 3 , the actuator 33 deflects in the counterclockwise direction. The left clamping leg 68a can contact the coupling tab 36 here, whereby the entire furniture drawer 12 is moved relative to the widthwise-position-fixed tension rail 29. In the example case shown, the furniture drawer 12 is moved to the left, whereby the above-mentioned problem can especially be eliminated in the region of the front element.

[0080] Figure 4 The clockwise deflection of the actuator 33 is shown, in which the right clamping leg 68b contacts the coupling tab 36, such that the furniture drawer 12 is moved to the right in this case.
