Description

State of the art

In the furniture sector, furniture is known which has a drawer which can be moved relative to a body, with a drawer front component being attached to drawer side parts via a drawer connecting device. The drawer front can preferably be attached detachably or interchangeably to the two drawer side parts, also called frames.

Fastening the drawer front to the drawer side parts in the area of the front end faces of the two drawer side parts, particularly when it comes to heavy or large fronts, requires skill and is often difficult. In addition, high forces must be absorbed by the connecting device in the connected state. Because of these forces, adjustment options for the connecting device in order to set a position of the drawer front relative to the drawer side part are constructed in a comparatively complicated manner, or a secure function of the adjustment options is not always reliably guaranteed. Known adjustment options are implemented, for example, by means of an adjustment device on the drawer side part and/or on the connecting device.

Previous drawer front connecting devices are also complicated to manufacture and/or have a multi-part design and require a comparatively large amount of free space on the two drawer side parts, so that satisfactory solutions are not available for all drawer designs. A generic drawer front connecting device is, for example CN 204 812 822 U known.

Object and advantages of the invention

The object of the present invention is to provide an improved drawer adjusting device for adjusting, in particular for adjusting the height of, a front connector of a drawer side wall of the type described in the introduction, in particular with regard to an economically advantageous production, a simplified assembly situation when assembling a drawer front on a drawer side part of any design and/or improved adjustment possibilities in order to adjust a position of the drawer front relative to the drawer side part.

This object is solved by the independent claims.

Expedient and advantageous developments of the invention are shown in the dependent claims.

The invention is based on a drawer adjustment device for adjusting a front connector of a drawer side wall, in particular a drawer height adjustment device for adjusting a front connector of a drawer side wall.

A drawer comprises, for example, a drawer front, a drawer base, a drawer rear wall and two drawer side walls or two drawer side parts or two drawer side frames, with one drawer side wall connecting the drawer front to the drawer rear wall when the drawer is in the arranged state. The drawer front includes an exterior surface and an interior surface. In the arranged state on the drawer, the inner surface of the drawer front delimits a drawer interior space and is located opposite a narrow side of the drawer side wall and/or protruding and/or adjoining the narrow side wall of the drawer. In the arranged state, the drawer base delimits the interior space of the drawer with a top side of the drawer base.

For example, a suspension component is present on the drawer front, in particular mounted and has connecting elements for connecting to a front connector. For example, the drawer adjustment device includes the front connector. For example, the connecting elements of the suspension component are designed to couple, in particular to latch, with a front connector of the drawer adjustment device.

A lateral adjustment of the drawer front relative to the side frame of the drawer takes place, for example, parallel to the plane of extension of the upper side of the drawer base and parallel to the narrow side of the side frame. A height adjustment of the drawer front relative to the side frame of the drawer takes place transversely, in particular perpendicular to the plane of extension of the top side of the drawer base and parallel to the side frame narrow side.

The drawer side wall extends in a longitudinal extension between the drawer front and the drawer rear wall. The drawer side wall has a drawer side wall inside which delimits the drawer interior space. A lateral adjustment of the drawer front relative to the drawer side wall of the drawer takes place, for example, transversely, in particular perpendicularly to the longitudinal extension of the drawer side wall and transversely, in particular perpendicularly to an extension plane of the drawer side wall inside. A height adjustment of the drawer front relative to the drawer side wall of the drawer takes place transversely, in particular perpendicular to the longitudinal extension of the drawer side wall and in particular parallel to the plane of extension of the drawer side wall inside.

The drawer side wall is advantageously designed as a hollow chamber frame. In the arranged state, the drawer adjusting device is, for example, in particular completely arranged in an interior space of the drawer side wall, for example a hollow chamber of the drawer side wall.

The drawer adjustment device is preferably provided between a drawer side wall in its front face area and the inner surface of the drawer front, so that the drawer front is connected to the two drawer side walls or to the remaining part of the drawer via two corresponding drawer adjustment devices.

The core of the invention is now to be seen in the fact that the drawer adjustment device comprises an outer housing, an inner housing and an adjustment arrangement, with the inner housing being present so that it can be displaced relative to the outer housing, with the adjustment arrangement having an adjustment element, a guide element and a link guide, with the The guide element is movably mounted on the slotted guide, with the slotted guide being formed on the inner housing, with the actuating element being mounted so as to be rotatable about an axis of rotation, with the actuating element being non-displaceable, in particular fixed in position, relative to the outer housing in a direction transverse to the axis of rotation, the guide element being in a Direction parallel to the axis of rotation is movable, wherein the actuating element and the guide element couple to each other in such a way that a rotary movement of the actuating element causes a movement of the guide element in a direction parallel to the axis of rotation. As a result, a comparatively simple, inexpensive and/or safe adjustment device for adjusting a front connector of a drawer side wall is realized.

For example, the actuating element is mounted on the outer housing such that it can rotate about an axis of rotation. Advantageously, the actuating element is non-displaceable in a direction transverse to the axis of rotation relative to the outer housing, in particular in a fixed position, for example mounted on the outer housing. For example, the actuating element is immovable in all directions transverse to the axis of rotation, in particular fixed in position relative to the outer housing, for example mounted on the outer housing. Advantageously, the actuator is in all directions mounted immovably, in particular in a fixed position relative to the outer housing on the outer housing, with a rotation of the actuating element, in particular about its own axis of rotation of the actuating element, nevertheless being ensured. For example, the actuating element is mounted immovably in a direction parallel to the axis of rotation of the actuating element, in particular in a fixed position relative to the outer housing on the outer housing, with rotation of the actuating element, in particular about its own axis of rotation of the actuating element, still being ensured. For example, there is a securing element which can be arranged on the actuating element and/or on the outer housing in such a way that movement, in particular displacement of the actuating element in a direction parallel to the axis of rotation of the actuating element on the outer housing, is prevented. The securing element is designed, for example, as a cotter pin, for example as a cotter pin spring and/or a disc spring.

It is further proposed that the adjusting element has an external thread.

The adjusting element is advantageously designed as a shaft, a hollow shaft or a screw. For example, the actuating element includes a screw thread. Preferably, the adjusting element, in particular in the form of a shaft or in the form of a hollow shaft, has a thread on its peripheral lateral surface. For example, the actuating element is designed as a worm shaft. It is also conceivable that the actuating element is present in the manner of a toothed rack.

It is also advantageous that the guide element has an internal thread. As a result, the actuating element can be coupled to the guide element in a comparatively simple manner.

The guide element preferably encompasses the actuating element. Advantageously, the guide element and the actuating element are movably coupled to one another, in particular via the thread. For example, the guide element and the actuating element are coupled to one another in a geared manner, in particular via the thread.

It is also conceivable that the guide element includes an engagement element with which it couples to the actuating element. The engaging element is designed, for example, in the manner of a tooth or a flag. Advantageously, the engagement member is protruding from the base body of the guide element. In particular, in the arranged state, the engagement element engages in threaded means, e.g. in a thread of the actuating element. It is also conceivable that the engaging member is designed like a toothed rack. For example, the guide element has rack-like pinions on an outer side of its base body. For example, the base body of the guide element, in particular the guide element, is present as a toothed rack.

Furthermore, it is advantageous that the guide element is mounted on the drawer adjustment device in a rotationally fixed manner.

For example, the internal thread of the guide element has an axis of rotation. The guide element is advantageously mounted on the drawer adjustment device, in particular on the inner housing, in such a way that a rotary movement of the guide element about the axis of rotation is blocked. For example, the inner housing includes guides, in particular guide surfaces, e.g. plain bearing surfaces, on which the guide element is movably, e.g. displaceably, e.g. Advantageously, the guide element is movably supported by the guide surfaces of the inner housing, e.g. displaceably, e.g.

In an advantageous variant of the invention, the guide element has a bearing journal, the guide element being coupled to the link guide via the bearing journal.

The bearing pin is advantageously provided protruding from the base body of the guide element. Advantageously, the guide element comprises, in particular, exactly two bearing journals. For example, the two bearing journals are opposite and spaced apart from each other on the guide element, e.g. the base body. The base body comprises, for example, an opening, e.g. a through opening, the opening comprising the internal thread. The bearing journal is advantageously designed as a pin, a journal and/or a bolt. In the arranged state, the bearing pin advantageously engages in the slotted guide, so that the guide element is guided by the slotted guide. An inverted design of the base body and the inner housing is also conceivable, in which the base body has link guides and the inner housing includes bearing journals which couple to the link guides of the base body.

It also proves advantageous that the outer housing is U-shaped, with the outer housing comprising a central element and a first side element and a second side element, with the central element connecting the two side elements to one another. Advantageously, the adjusting element is rotatably mounted on the two side elements.

Preferably, the two side members are opposite and spaced from each other. The first and the second side element are advantageously arranged protruding, in particular protruding in the same direction on the central element. For example, the outer housing is designed in one piece. For example, the outer housing is present as a flexure, e.g., as an angle member.

If the securing element is designed as a plate spring, the securing element can advantageously be arranged on the actuating element in such a way that the actuating element is movable in a direction parallel to the axis of rotation of the actuating element against a spring force of the plate spring Spring force of the plate spring acts between a side element of the outer housing and the actuating element. The disk spring is advantageously supported on a side element of the outer housing.

Advantageously, the outer housing includes a mounting element for mounting the outer housing, in particular the drawer adjustment device, to the side wall of the drawer.

It is also preferred that the housing elements of the outer housing enclose an inner volume, the inner housing being movably arranged in the inner volume of the outer housing. For example, the case members of the outer case include the side members and the center member.

In addition, it is advantageous that the outer housing has guide lugs, so that the inner housing is mounted on the outer housing by means of the guide lugs, in particular exclusively in a linearly movable manner. Advantageously, the inner housing is displaceable, in particular linearly displaceable, for example in a straight line to the outer housing. For example, the inner housing is, in particular, exclusively displaceable, in particular linearly displaceable, on the outer housing.

A guide tab of the outer housing is advantageously present at an angle on a side element of the outer housing. For example, a guide tab is spaced and opposite the central member. A first guide tab is advantageously arranged on a first side element and a second guide tab on a second side element of the outer housing, the guide tabs being spaced apart from one another. For example, the housing elements of the outer housing, side element, middle element, guide tabs are present in one piece. Preferably, the inner housing is movably mounted, in particular displaceably mounted, on the side elements, the central element and/or the guide tabs. For example, a first guide tab protruding in the direction of a second guide tab on the first side element. For example, the second guide tab is present on the second side element, protruding in the direction of the first guide tab.

It also proves to be advantageous that the axis of rotation of the actuating element is aligned transversely to the linear directions of movement of the inner housing. The axis of rotation of the actuating element is preferably aligned transversely to the direction of displacement of the inner housing relative to the outer housing.

The actuating arrangement preferably comprises a locking element and, for example, a locking element, the locking element being movable relative to the outer housing, the locking element advantageously being formed on the outer housing, a spring element also being present, for example, so that the locking element can be moved from a first position on the outer housing to a second position on the outer housing against a spring force of the spring element, the locking element being coupled in the first position to the actuating element and e.g. to the locking element in such a way that a rotary movement of the actuating element is blocked, the locking element being decoupled from the locking element in the second position is, so that a rotary movement of the actuating element can be realized. For example, the locking element can be moved from the first to the second position independently of the actuating element. Advantageously, the locking element is movable along and/or parallel to an axis of rotation of the actuating element relative to the actuating element.

It is also advantageous that the actuating element and the locking element are coupled in such a way that, in the first position of the locking element, a rotary movement of the actuating element and the locking element is prevented, for example locked or blocked, in particular by the coupling of the locking element to the locking member. It is also advantageous that the actuating element and the locking element are coupled in such a way that in the second position of the locking element a particular joint rotary movement of the actuating element and the locking element can be realized. Advantageously, the locking element rotates about an axis of rotation, in particular about an axis of rotation of the locking element, which is parallel to a displacement direction of the locking element.

Moreover, it is advantageous that the locking element latches, in particular is latched, in the first position with the latching member. As a result, a rotary movement of the locking element, in particular about the axis of rotation of the locking element, is prevented, for example blocked or impossible. Advantageously, the locking element comprises a cylindrical body. For example, the locking element is designed as a cylindrical body, with locking teeth being formed projecting circumferentially on the cylindrical body. It is also conceivable that recessed locking receptacles are present on the cylindrical body. The ratchet teeth and/or the ratchet receptacles are advantageously present, in particular evenly or e.g. regularly spaced apart from one another. For example, the locking element is provided in the form of a toothed ring, e.g. designed as a toothed ring. It is also conceivable that the locking element has a polygon around its circumference, e.g. in cross section, or is designed in the shape of a polygon, e.g. as a pentagon or as a hexagon. The locking member is advantageously designed to be complementary to the locking element. For example, the locking member is star-shaped or honeycomb-like. As a result, several, in particular different, latching positions of the locking element can be implemented relative to the locking element and/or to the outer housing.

In addition, it is proposed that the spring element is present on the drawer adjustment device in such a way that the locking element is automatically moved from the second position into the first position due to a spring force of the spring element. As a result, a comparatively simple and reliable self-locking, self-locking and/or self-latching of the locking element and thus of the actuating element is realized. Advantageously, the spring member is so at the Drawer adjustment device arranged that at least one main force component of the spring force of the spring member acts parallel to the axis of rotation of the locking element and / or to the axis of rotation of the actuating element on the locking element.

In an advantageous modification of the invention, the link guide is designed in such a way that the guide element is displaceable in a direction parallel to the axis of rotation of the actuating element and in the direction of the linear movement directions of the inner housing. The link guide is preferably designed in such a way that the guide element is displaceable in a direction parallel to the axis of rotation of the actuating element and in the direction of the linear movement directions of the inner housing relative to the outer housing.

The link guide is designed, for example, as a slot or as a gap. Advantageously, the slot or gap runs diagonally or at an angle to the linear movement directions of the inner housing and/or diagonally or at an angle to the axis of rotation of the actuating element.

Advantageously, the slotted guide is connected to the inner housing in a fixed position. For example, the inner housing includes the link guide. For example, the link guide is present in one piece with the inner housing.

When the guide element moves along an axis of rotation of the actuating element, the guide element preferably forces the link guide and thus the inner housing to move in a displaceable manner relative to the outer housing. As a result, the height of the inner housing is adjusted relative to the outer housing and thus the height of the drawer side wall is adjusted relative to the front connector and/or the drawer front.

An advantageous embodiment of the invention is a drawer side wall with a drawer adjustment device according to one of the embodiments described above, wherein the outer housing of the drawer adjustment device is arranged on the drawer side wall.

The front connector preferably has two or more connector plates, the connector plates being arranged at a distance from one another and connected to one another by means of a connecting element. For example, the connecting element permanently connects the connector plates to one another. The connecting element is present, for example, as a bolt and/or a rivet. For example, the connector plates are riveted and/or welded together. Advantageously, the front connector comprises three or four connector plates.

It is also advantageous that the front connector has at least two connector plates aligned in parallel and connected to one another. For example, the first and/or the second connector plate of the front connector are each formed as a continuous plate component. The connector plates are spaced from each other in a width direction of the front connector, for example. Preferably, the connector plates are symmetrical. The connector plates are, for example, arranged mirror-symmetrically to one another. It is also conceivable that the connector plates are identical. For example, each connector plate has parallel face sides and in between according to the thickness of the plates existing narrow sides, comprising an upper and a lower narrow side.

Advantageously, the inner housing comprises two opposite side parts that are spaced apart from one another, with at least two guide elements being present, with one guide element connecting the two side parts to one another, the guide elements being spaced apart from one another on the inner housing, each guide element having a longitudinal axis, the front connector being attached to the guide organs is mounted exclusively parallel to a side part along the longitudinal axes of the guide organs.

1 shows a piece of furniture 1 with a drawer 2 protruding at the front of the piece of furniture 1 or moved out as far as possible on the piece of furniture 1. The drawer 2 can be moved or is shown in FIG Furniture usage state recorded linearly displaceable in the horizontal direction via guide means 4 on a furniture body 3 of the piece of furniture 1. The piece of furniture 1 is, for example, in the form of a box piece of furniture, with opposite side walls 5, 6, a floor 7, a rear wall 8 and two transverse boards 10, 11 on the upper side. The transverse board 10 is horizontal at the top between the two side walls 5, 6 in the front area of the piece of furniture 1 and the transverse board 11 is horizontally present at the top between the two side walls 5, 6 in the rear area of the piece of furniture 1, whereby the two side walls 5, 6 are connected to the bottom 7 and the rear wall 8 in a stable manner. A covering plate to be provided above the two transverse boards 10, 11 on the piece of furniture 1 is not shown.

The guide means 4 comprise a left rail guide 13 and a right rail guide 14, the rail guides 13, 14 acting between the furniture carcass 3 and the drawer 2 and being designed, for example, as a full extension 12 with rails that are in particular telescopically displaceable in relation to one another. The right-hand rail guide 14 mirrored to the rail guide 12 on the item of furniture 1 is in 1 completely hidden.

Drawer 2 is in 2 shown alone without a drawer front 15. Further elements of the drawer 2 are a drawer bottom 16, a left drawer side part 17, a right drawer side part 18 and a drawer back 19.

The two similar drawer side parts 17 and 18 are formed here as drawer frames or as hollow chamber frames, for example formed from folded sheet metal material. The drawer side parts 17 and 18 are open at their front end 17a or 18a and are designed for connection to the drawer front 15 by means of a drawer adjustment device 9 in each case. A first drawer adjusting device 9 is provided for connecting the drawer front 15 to the drawer side part 17 and for connecting the drawer front 15 to the drawer side part 18 a second drawer adjustment device 9 is provided. Since the connection of the drawer front 15 to the respective drawer side part 17 or 18 is, for example, set up identically or takes place with an identical drawer adjustment device 9 in each case, the connection is described below as an example for a drawer side part.

In 3 the drawer front 15 is shown transparently and is therefore not shown, but merely indicated in outline or schematically as a detail in dashed lines.

The drawer adjustment device 9, which is designed as a multi-part structural unit, comprises an outer housing 20, an inner housing 21, a front connector 22, at least one actuator 23, 24 and, if necessary, a suspension component 25.

The elements 20 , 21 , 22 , 23 and 24 can advantageously be combined in a recessed receiving area at the front end 18a of the drawer side part 18 but can be accommodated in a fixed but detachable manner. The suspension component 25 is designed to be fixed, for example screwed, to an inner side 15a of the drawer front 15 . The drawer front 15 is connected to the drawer side parts 17 and 18 via the respective interaction of a suspension component 25 with an associated front connector 22. For this purpose, the component from the combined elements 20, 21, 22, 23 and 24 is on the front of each drawer side part 17, 18 accommodated. For the connection state, these components interact with a respective associated suspension component 25 . For this purpose, on the inside 15a of the drawer front 15, exactly two suspension components 25 are fixed at a point that is coordinated for this.

The connection is then made by hanging the drawer front 15 on the respective front connectors 22 on the two drawer side parts 17 and 18 via the two hanging components 25 on it.

The elements 20, 21, 23, 24 and 25 and a sliding element 31 on the front connector 22 are used to adjust the height and side of the drawer front 15 on the rest of the drawer or on the drawer side parts 17 and 18.

The front connector 22 has two narrow, preferably essentially plate-shaped connector plates 26 and 27, a spring 28, a latching element 29 and a bearing element 30 for the deflectable mounting of the latching element 29 on the connector plates 26, 27. The spring 28 is on the two connector plates 26 , 27 and causes the latching element 29 to be somewhat yieldable or pivotable about the longitudinal axis of the bearing element 30 and biased in a first pivoting direction. The latching element 29 can be deflected in the second pivoting direction R2, which is opposite to the first pivoting direction. The ability to avoid being used serves to cancel a latching, which can be set up automatically by the latching element 29 , with which the suspension component 25 can be latched on the front connector 22 . The latching is canceled by manually pressing from the outside against an operating section 29a on the latching element 29 against the force or spring action of the spring 28.

Between the first connector plate 26 and the second connector plate 27, the displacement element 31 belonging to the lateral adjustment is accommodated. The actuator 24 that can be rotated from the outside about its longitudinal axis is provided for this purpose. For this purpose, the actuator 24 reaches across through openings in the outer housing 20, the inner housing 21, the two connector plates 26, 27 and the displacement element 31.

The two connector plates 26, 27 are aligned parallel to one another and are spaced apart from one another in a width direction B of the front connector 22 by a distance over the predominant extent and are firmly connected to one another by elements that are not specifically shown, such as transverse bolts 83 to 85. The longitudinal axes 32 of the elements or the cross bolts are in 4 indicated by dashed lines, each element with its two ends on the associated Connector plate 26 or 27 is firmly connected. The transverse bolts 83 to 85 are preferably aligned parallel in the width direction B or in particular parallel to the bearing element 30 .

An upper ramp 33 and a lower ramp 34 are present on the front connector 22 at a distance from one another in a vertical direction H of the front connector 22 . The planar ramps 33 , 34 are oriented obliquely in a depth direction T of the front connector 22 and slope backwards away from a front side 35 of the front connector 22 or towards a rear side 36 of the front connector 22 .

The upper ramp 33 has an upper narrow side 33a of the first connector plate 26 and an upper narrow side 33b of the connector plate 27 . The narrow sides 33a and 33b lie in a common spatial plane. Correspondingly, the lower ramp 34 has a lower narrow side 34a of the first connector plate 26 and a lower narrow side 34b of the connector plate 27 . The narrow sides 34a and 34b lie in a common imaginary spatial plane which is parallel to the spatial plane of the upper narrow sides 33a, 33b.

Support sections 37 and 38 of the suspension component 25 are preferably of the same type or identical. The support sections 37, 38 are preferably formed as pin-like or elongated components, here for example as a pin or bolt with a concave or cylindrical outer shape. Other shapes such as a polygonal outer shape of the support sections 37, 38 are also possible.

To fasten the suspension component 25 to the drawer front 15, openings 41, 42 and 43 are formed on the suspension component 25 on a component rear side 39 of a base body 40 of the suspension component 25 for the fastening elements to reach through (see Fig. 3 ) .

The in the Figures 5 to 10 shown drawer adjustment device 44 according to the invention is advantageously in accordance with the in the Figures 1 to 4 shown embodiment of the furniture 1 to the drawer side parts 17, 18 can be arranged interchangeably.

The inner housing 45 of the drawer adjustment device 44 according to the invention comprises side parts 56, 57, a middle part 58, which connects the two side parts 56, 57, and a front part 59, which is opposite and spaced from the middle part 58. On the middle part 58 and on the front part 59 there is advantageously one link guide 50 each. The other elements of the inner housing 45 are, for example, identical or at least approximately similar to the elements of the inner housing 21 of the drawer adjustment device 9.

The actuating element 48 is designed, for example, as a cylindrical screw, with an external thread 62 being formed on the actuating element 48 on a cylinder jacket surface 61 along a longitudinal axis L of the actuating element 48, advantageously over a partial area. For example, an external thread 62 is present along the longitudinal axis L for approximately half of the total length of the actuating element 48 . For example is An external thread 62 is formed over less than half of the total length of the actuating element 48 along the longitudinal axis L, for example over a third of the total length of the actuating element 48 along the longitudinal axis L. Advantageously, the actuating element 48 comprises an operating element 63 by means of which the actuating element 48 can be rotated from the outside, in particular about its longitudinal axis L, by a user, for example by means of a tool. The operating element 63 is designed, for example, as a screw head, for example as a Phillips or Torx screw head.

The adjusting element 48 is rotatably mounted on side elements 64, 65 of the outer housing 46 (see in particular 7 ). At the in figure 6 shown illustration of the mounted control element 48 on the inner housing 45 is to install the outer housing 46, the control element 48 and in particular the plate spring 66 designed for example as a fuse to remove. Advantageously, the adjusting element 48 reaches through the side elements 64, 65 of the outer housing 46. For example, the outer housing 46 includes openings 86, 87 for this purpose, which are designed, for example, as pivot bearings.

It is advantageous that the outer housing 46 is U-shaped, with the outer housing 46 having a central element 67 connecting the two side elements 64, 65 to one another. In addition, the outer housing 46 can include a mounting element 68 for mounting the outer housing 46, in particular the drawer adjustment device 44, to the drawer side wall 55.

The outer housing 46 also includes, for example, guide lugs 69, 70, so that the inner housing 45 is mounted on the outer housing 46 by means of the guide lugs 69, 70, in particular in an exclusively linearly movable manner. The housing elements of the outer housing 46 enclose an inner volume 71 in which the inner housing 45 is arranged in the assembled state. Advantageously, the inner housing 45 is movably mounted on the outer housing 46, in particular displaceably. For this purpose, inner surfaces 72 of the Outer housing 46 and outer surfaces 73 of the inner housing 45 are advantageously designed in the manner of plain bearings, in particular as plain bearing surfaces.

A base body 74 of the guide element 49 is designed, for example, in the form of a sliding block, for example cuboid, e.g. as a cuboid. On the base body 74 , bearing journals 75 , 76 that are opposite one another and are spaced apart over a depth of the base body 74 are formed so as to protrude from the base body 74 . Furthermore, the base body 74 advantageously includes a through-opening 77 with an internal thread 78. In the installed state, the actuating element 48 engages through the through-opening 77 in the base body 74 of the guide element 49.

In the mounted state, the bearing journals 75, 76 engage in the link guides 50. By rotating the adjusting element 48 about its longitudinal axis L, which advantageously also forms an axis of rotation of the adjusting element 48 at the same time, the guide element 49 is positioned between the side parts due to a coupling of the external thread 62 of the adjusting element 48 to the internal thread 78 of the guide element 49 along the longitudinal axis L of the adjusting element 56, 57 movable back and forth. For this purpose, link guide 50 is designed as a slot 60, for example. The slot 60 advantageously runs diagonally or at an angle to the linear movement directions of the inner housing and/or diagonally or at an angle to the axis of rotation of the actuating element. As a result, the inner housing 45 is displaced transversely to the longitudinal axis L of the adjusting element 48 relative to the outer housing 46 in the height direction, as a result of which a height adjustment can be implemented. The guide element 49 is advantageously mounted and/or held between the central part 58 and the front part 59 in a rotationally fixed but displaceable manner.

In the assembled state, the external thread 62 of the actuating element 48 extends between the inner surfaces 79 of the side parts 56, 57 of the inner housing 45 along the longitudinal axis L of the actuating element L, advantageously not over an entire distance of Inner surfaces 79 of the side parts 56, 57 to each other. For example, the external thread 62 of the adjusting element 48 extends between the inner surfaces 79 of the side parts 56, 57 of the inner housing 45 along the longitudinal axis L of the adjusting element L over three quarters, for example over three quarters, of the distance between the inner surfaces 79 of the side parts 56, 57. As a result, the guide element 49 is advantageously protected relative to the adjusting element 48 against over-tightening and thus destruction of the threads of the two elements, or destruction of the threads is thereby prevented. For example, the external thread 62 is designed in such a way that when the base body 74 of the guide element 49 is moved toward an inner surface 79 of the side part 56, i.e., for example, when the base body 74 is in physical contact with the inner surface 79 of the side part 56, the outer thread 62 and the inner thread 78 are decoupled from each other.

The external thread 62 is advantageously designed in such a way that in a position of the base body 74 in which the base body 74 is in contact with an inner surface 79 of one of the side parts 56, 57, the external thread 62 cannot be engaged with the internal thread 78 if the adjusting element 48 is rotated in a direction of rotation, through which the base body 74 could be moved towards the side part 56, 57 on which it rests, whereas in the opposite direction of rotation of the adjusting element 48, through which the base body 74 can be moved away from the side part 56, 57 on which it rests is moved away, due to a spring force of the plate spring 66, the external thread 62 is available so that it can engage in the internal thread 78, as a result of which the base body can be moved away in this direction from the corresponding inner surface 79 on which it rests (see in particular figure 8 ).

In the Figures 9 and 10 is the drawer adjustment device 44 according to the Figures 5 to 8 shown, wherein another variant of a front connector 80 is shown. The front connector 80 differs from the front connector 51 the figure 6 advantageously only in its formation of the upper ramp 81. In figure 10 it is shown that the front connector 80 in the arranged state on the drawer adjustment device 44 with its recess 82 surrounds the adjustment arrangement 47 and in particular the adjustment element 48, the guide element 49 and the front part 59 of the inner housing 45 at least above and below and on one side. The front connector 80 can be arranged on the inner housing 45 in such a way that the front connector 80 and the inner housing 45 can be displaced together relative to the outer housing 46 by means of the actuating arrangement 47 . <u>Reference List</u> 1 Furniture 37, 38 support section 2 Drawer 39 component rear 3 furniture body 40 body 4 means of guidance 41 - 43 opening 5, 6 Side wall 44 Drawer adjustment device 7 Floor 8th back panel 45 inner case 9 drawer 46 outer case adjusting device 47 setting arrangement 10, 11 cross board 48 actuator 12 full extension 49 guide element 13, 14 rail guide 50 link guide 15 drawer front 51 front connector 15a inside 52 recess 16 drawer bottom 53, 54 connector plate 17 drawer side panel 55 drawer side panel 17a, 18a End 56, 57 side part 18 drawer side panel 58 center part 19 drawer back 59 front part 20 outer case 60 slot 21 inner case 61 cylinder surface 22 front connector 62 external thread 23, 24 actuator 63 control element 25 suspension component 64, 65 page element 26, 27 connector plate 66 disc spring 28 Feather 67 center element 29 latching organ 68 assembly organ 29a operating section 69, 70 guide tab 30 bearing element 71 internal volume 31 sliding element 72 Inner surface 32 longitudinal axis 73 outer surface 33, 34 ramp 74 body 33a, 33b narrow side 75, 76 bearing journal 34a, 34b narrow side 77 passage opening 35 front 78 inner thread 36 back 79 Inner surface 80 front connector 83 - 85 cross bolt 81 ramp 86, 87 opening 82 recess
