Description

State of the art

Adjusting devices for furniture with a furniture body on a guide unit movably received movable furniture part are known, wherein the guide unit engages on the one hand on the movable furniture part and on the other hand on the furniture body. If the guide unit is, for example, a full extension for the displaceable movement of an extension or a drawer, the guide unit has a drawer rail engaging the drawer, a carcass rail engaging the furniture carcass, and a middle rail, the rails being telescopically displaceable relative to one another. A guide unit can also be understood to mean a hinge, for example, for a pivotably movable furniture flap or furniture door.

For example, aperture setting devices with a tilt adjustment of the movable furniture part accommodated on the guide unit are in use, wherein the guide unit is not adjusted in its position or inclination itself relative to the furniture body. With the adjustment is a tendency of lying in a field of view of the furniture front part made of the movable furniture part. With a tilt adjustment of the front part, in particular a desired optical appearance of a front side of the furniture can be set up with exactly aligned component edges or uniform distances between adjacent movable furniture parts. For example, lifting or lowering devices are used for the movable furniture part, with which an adjustment of the inclination or pivoting of the movable furniture part and thus the front part takes place about a horizontal or about a corresponding pivot axis during an adjustment. An adjusting device is set up, for example, in a front region of the movable furniture part, that is to say in a region which faces an operating side of the furniture.

With regard to a stable support of the movable furniture part, it is disadvantageous that with the adjustment, the movable furniture part is pivoted along a point or line support of the furniture part.

Such adjusting is from the EP 1421876 A known.

Purpose and advantages of the invention

The object of the present invention is to provide arrangements of the above-mentioned type, which are improved over previous arrangements.

This object is solved by the independent claims.

The dependent claims relate to advantageous variants of the invention.

The invention relates to a device for adjusting the inclination of a movable furniture part with a front part relative to a furniture body to which the movable furniture part is received via a guide unit, and the movable furniture part is supported in contact with a bearing element of the adjusting device on the guide unit, wherein the guide unit has a carcass unit acting on the furniture carcass and a connectable to the movable furniture part furniture unit comprises, and wherein the adjustment between the movable furniture part and the guide unit is provided such that depending on the adjustment of the adjustment, the inclination of the movable furniture part relative to the furniture body is predetermined by the bearing element in different positions relative can be brought to the guide unit.

The essence of the invention is to be seen in that a displacement element is provided, which is displaceable along the guide unit and that on the displacement element, the bearing element is supported such that by displacing the displacement element along the guide unit, the bearing element on a sloping or curved path a shift the height position relative to the guide unit performs. Advantageously, a surface support is provided with this arrangement, in particular between sections of the adjusting device and the guide unit. With the arrangement according to the invention, it is possible that with the displacement of the displacement element along the guide unit or with the reciprocating, a flat support for the displacement element is maintained. In this case, the bearing element, which is coupled to the movable furniture part, displaced on an inclined or curved path relative to the guide unit. The changing height position of the bearing element during adjustment thereby leads to the height position displacement of the movable furniture part. Pivoting or tilting parts of the adjusting device via a point or a line relative to the guide unit, which z. As regards the occurring in the contact area highest component loads is disadvantageous, is avoided.

Furthermore, the interaction between the furniture part and guide unit can be made compact and stable, in an area of storage or support of the movable furniture part on the guide unit, ie where the adjustment is present interacting.

In addition, with the displacement of the displacement element over all adjustment positions and consistently improved and more reliable support on the guide unit can be achieved. Because in all adjustment positions, the displacement element remains flat in contact with the guide unit. In addition, it is easily possible, the inclination of the movable furniture part infinitely z. B. make a fine adjustment relative to the furniture body.

The inventive principle of the front inclination adjustment can be used advantageously for all types of movable furniture parts, for example for drawers, doors or flaps.

It is further proposed that the bearing element is fixed in the direction of displacement of the displacement element. In particular, the bearing element is guided on the positionally fixed between the bearing element and the displacement element intermediate member of the adjustment in its movement to shift the height position movement. Thus, a height adjustment of the relevant portion of the movable furniture part is allowed in relation to the guide unit.

Preferably, an intermediate component of the adjusting device is present, which is designed for positionally fixed attachment to the guide unit, on which the displacement element and / or the bearing element are guided during the adjustment movement. The intermediate component is in particular releasably fixable, for example, attachable to a mating portion of the guide unit, for example, on a protruding hook portion on an upper side of a furniture part unit or drawer rail. Thus, the adjusting device is fixed to the guide unit, the relative movement of the bearing element in the height adjustment direction and the displacement element in the direction of displacement, however, remains with respect to the intermediate component.

The fixation of the bearing element in the direction of displacement of the displacement element is preferably by a corresponding Realized guide contour on the intermediate component, in which a counter portion of the bearing element is slidably engaged or received.

The intermediate component provides the sliding element in particular a guide surface together with support for the defined sliding movement in the direction of displacement. In addition, z. B. transversely to a lifting of the displacement element relative to the guide unit, which is undesirable because it would influence the height position of the bearing element undefined, be prevented by further corresponding guide contours on the intermediate component. In particular, the intermediate component is designed such that a jerk-free reciprocating movement of the displacement element and of the bearing element can take place thereon.

Advantageously, the adjusting device comprises a slotted guide with at least two engaging elements on the displacement element, wherein an engagement element is associated with a guideway, which cooperate such that during displacement of the displacement element, a displacement of the height position of the bearing element takes place relative to the guide unit. The displacement is in particular positively controlled in both directions, that is to say in the case of a reduction as well as an increase in the height position of the bearing element relative to the guide unit. Thus, a characteristic increase of the bearing element and thus of the movable furniture part can be realized individually for an adjustment. In particular, each of the engaging elements moves during an adjustment process along each of the respective engaging element associated guideway of the slotted guide. In this way, desired trajectories can be accurately tracked or specified. The engagement elements and the guideways may possibly be coordinated with one another such that only a linear movement of the bearing element takes place during the adjustment process, or a movement which comprises at least a portion of a non-linear movement, for example. B. has a pivoting movement.

Preferably, at least two guideways for the at least two engagement elements are formed substantially obliquely to a displacement direction of the displacement element. Thus, the adjustment can be designed compactly.

For securing a set adjustment position, at least one guideway may be provided with a tooth contour which cooperates with a mating contour matching the tooth contour on the engagement element which runs along the relevant guideway, so that an automatic adjustment of a set adjustment position is prevented. This can be done for example by a hooking together of tooth contour and counter contour.

It is further proposed that the at least two engagement elements are offset from one another with respect to the displacement direction of the displacement element. This measure increases the balanced guidance of the displacement element relative to the bearing element.

The displaced on the displacement element in the displacement direction at least two engaging elements are preferably formed in each case with paired protruding in particular aligned zueinender aligned Eingreifenden that may be present outwardly above the sliding element. There are thus preferably at least four engagement ends present per engagement element two, which cooperate respectively with the slotted guide, ie in particular in accordance with four guide contours of the slotted guide z. B. engage in four curved or oblique slots.

For guiding the displacement element relative to the intermediate component as described above, the engagement elements or engagement ends can additionally engage in guide contours on the intermediate component, for example in elongated holes of the intermediate component.

It is also advantageous that the displacement element is adjustable relative to the bearing element via an operable in the assembled state of the adjusting actuator assembly. Thus, a desired inclination adjustment can be made externally, in particular by a user or a fitter. The operable positioning arrangement can function via one of different operating mechanisms, in particular, the adjusting arrangement can be adjusted via an operating tool or manually.

It is particularly advantageous that the actuating arrangement comprises a toothed-gear arrangement, an eccentric arrangement and / or a drive-rod arrangement. Thus, the actuator assembly can be made compact and reliable.

It is further proposed that the toothed gear arrangement comprises a pinion which is rotatably mounted on the bearing element and the pinion meshes with an adjusting operation with a tooth portion on the displacement element. The pinion has for this purpose a pinion section. With a pinion and a toothed gear arrangement, an exact adjustment or adjustment can optionally be set up in a confined space in a self-locking manner. The pinion may be externally accessible, for example, having an engaging portion for mating engagement of an operating tool.

The displacement element may be surrounded by the bearing element in the manner of a housing, so that the engagement of the pinion portion takes place in the tooth portion of the displacement element in the interior of the adjusting device.

In an advantageous modification of the subject invention, the pinion and the tooth portion are coordinated such that the pinion is supported in an end position relative to the tooth portion of at least two teeth of the tooth portion. In particular, the pinion rolls on the tooth portion, wherein in each end positions of the pinion relative to the tooth portion advantageously an end stop is provided, the tooth geometry to a relatively high torque value nondestructive works.

In particular, it can be avoided that a tooth of the tooth geometry or the pinion portion is damaged or possibly completely failed and, for example, breaks off. In addition, slipping or spinning of the pinion in an end position is reliably avoided.

In addition, it is preferred that the displacement element is displaceably guided on a bearing fixed relative to the guide unit. The positionally fixed support opposite the guide unit is provided in particular by a region of the intermediate component.

Moreover, it is advantageous that a separate tension element is provided, which is connectable to the displacement element, so that in the connected state of tension element and displacement element, the tension element provides an additional guidance and / or support to the displacement element. For larger sized movable furniture parts more than one tension element can be attached. For smaller movable furniture parts, an additional tension element can be omitted.

The invention also relates to a piece of furniture with a furniture part including front part, wherein the furniture part is movably received relative to a furniture body via a guide unit, wherein the guide unit comprises a carcass unit engaging on the furniture carcass and a furniture subunit connectable to the movable furniture part, one of the above-mentioned devices is available. Thus, an arrangement with the explained advantages can be realized on a piece of furniture.

In particular, a drawer or an extension which is displaceably guided via a partial or full extension is provided on the furniture, in which a lifting of the drawer relative to the full extension or partial extension and thus an inclination of the drawer relative to the guide unit is possible.

Further features and advantages of the invention are explained in more detail with reference to a concrete embodiment and an arrangement shown only in the basic principle.

FIG. 1 shows in perspective obliquely from above an adjusting device 1 according to the invention, which can be used to adjust the inclination of a movable furniture part together with the front part relative to a furniture body, in which the movable furniture part is received via a guide unit. The movable furniture part may for example be a drawer, which is displaceable by means of a partial or full extension of the furniture body.

FIG. 1 shows that from the items according to FIG. 2 to FIG. 5 assembled component which forms the adjusting device 1. The adjusting device 1 accordingly comprises a housing 2 designed as a bearing element, a rotatably mounted on the housing 2 Verstellritzel 3, a Displacement element, which is formed as displaceable relative to the housing 2 recorded Verstellkeil 4, and a Neigungsverstellhebel 5. In addition, in FIG. 6 In perspective, a pulling wedge 6 is shown, which can be attached to a connecting end 7 of the adjusting wedge 4 selectively or detachably.

FIG. 7 shows the adjustment device 1, which is attached to the housing 2 on a drawer frame 10 and the tilt adjustment lever 5 on an upper side 8 of a drawer rail 9, so that the drawer rail 9 via the adjustment device 1 with a drawer or here with a drawer 10 of the drawer is coupled. The adjusting device 1 is positioned at a rear end region of the drawer rail 9, which is opposite to the furniture of a front or operating side of the furniture.

FIG. 8 shows enlarged the rear end and a rear end portion of the drawer rail 9 and the drawer frame 10 with the attached adjustment device 1, which is in a first end position with respect to a tilt adjustment of the drawer or the drawer frame 10, not shown.

FIG. 9 In contrast, shows a second end position with respect to a tilt adjustment of the drawer or drawer 10.

The adjustment of the adjusting device 1 or the displacement of the adjusting wedge 4 is effected by the action of the in FIG. 10 For this purpose, a cross-slot-shaped recess is formed on the adjusting pinion 3 to the Verstellritzel 3 according to the double arrow P3 (see FIG. 10 ), for example, with a Phillips screwdriver to twist.

Transverse to the longitudinal extent of the adjusting wedge 4 projecting engagement elements are formed on both sides, which as Gleitnasen 11 to 14 are configured. At a front end region in the longitudinal direction of the adjusting wedge 4, which is directed in the installed state of the adjusting device 1 to a front side of the drawer, the sliding lugs 11 and 12 are formed, which respectively have tooth-shaped notches 11a and 12a on the top and bottom. The notches 11a, 12a are used for locking the Verstellkeils 4 in a setting position relative to the housing 2. For this purpose, in the slot-shaped guideways 15, 16 in the housing 2, which serve as gate guide for the Gleitnasen 11 and 12, a corresponding to the notches 11a, 12a tuned tooth portion 17 on opposite flanks of the guideway 15, 16 is formed (see FIGS. 1 and 2 ). In the other relevant figures with the housing 2, the tooth portion 17 is not shown in detail.

The further sliding lugs 13 and 14 present in the longitudinal direction in a rear section of the adjusting wedge 4 slide without latching possibility into guide tracks 18, 19 on the side of the housing 2, which accordingly also have no corresponding tooth section. At the rear end of the adjusting wedge 4, following the sliding lugs 13, 14, a wedge portion 20 is present with sloping top. An underside of the adjusting wedge 4 slides during the displacement of the adjusting wedge 4 relative to the housing 2 and the inclination adjusting lever 5 on a sliding surface 21 of the inclination adjustment lever fifth

When adjusting the adjusting device 1 by turning the Verstellritzels 3 of the adjusting wedge 4 is in accordance with the double arrow P1 in FIG. 11 moved along the sliding surface 21 and moved in these directions relative to the housing 2 and the tilt adjustment lever 5. In this case, slide the sliding lugs 11 to 14 in the guideways 15, 17, 18, 19. Furthermore slide the sliding lugs 14 and 12 in slots 22, 23, which are formed in a perpendicular to the sliding surface 21 upstanding central portion 24 of the tilt adjustment lever 5. The slots 22 and 23 are offset in the longitudinal direction of the tilt adjustment lever 5 and the adjusting device 1 and aligned with each other or one behind the other at a constant distance from the sliding surface 21. The Verstellkeil 4 is also provided on the upper side with a support surface 27, which guided on the underside of a web 5a of Neigungsverstellhebels 5 slidably. The adjusting wedge 4 can therefore only move in the directions according to P1, but not lift off the tilt adjustment lever 5 upwards.

When adjusting the adjusting device 1 by rotating the housing fixedly mounted adjusting pinion 3 rolls a pinion or tooth portion 3a of Verstellritzels 3 in an opening 25 of the Verstellkeils 4, wherein an edge at a lower edge 25 of the opening with a matched to the tooth portion 3a Counter tooth portion 26 is provided. Two adjustment states show, for example, the FIGS. 13 and 14 , By the engagement of the slide lugs 12 and 14 in the slots 22, 23 of the tilt adjustment lever 5 of the Verstellkeil 4 is perpendicular to the displacement directions according to arrow P1 and in the direction of the double arrow P2 in FIG. 11 fixed in position. The underside of Verstellkeils 4 always slides defined on the sliding surface 21. This requires when moving the Verstellkeils 4 by the engagement of Gleitnasen 11 to 14 in the guideways 15, 16, 18, 19 that the housing 2 according to the double arrow P2 in its vertical position relative adjusted to the top 8 of the drawer rail 9 or raised or lowered. The drawer or the drawer frame 10 is accordingly supported via the housing 2 via the sliding lugs 11 to 14 on the adjusting wedge 4, which in turn is supported on the drawer rail 9.

With the displacement of the adjusting wedge 4, the housing 2 is adjusted in its height position via the interplay of the sliding lugs 11 to 14 in the guideways 15, 16, 18, 19. Since the tilt adjustment lever 5 is fixedly fixed to the drawer rail 9, relative to the drawer rail 9 is a tilt adjustment of the drawer frame 10 together with drawer relative to Drawer rail 9 instead. This is in particular from the two end positions according to FIG. 8 and FIG. 9 clear. FIG. 8 shows an end position in which over the length of the drawer frame 10, this is aligned parallel to reference edges in the longitudinal extent of the drawer rail 9, based on a height position according to arrow P2 in FIG. 11 , A distance between the top 8 of the drawer rail 9 and one end 10a of the drawer 10 is a minimum adjustable value a0.

FIG. 9 In contrast, shows a further end position of the adjusting device 1, in which a rear end portion with the end 10a of the drawer 10 is raised relative to the rear end of the drawer rail 9, so that relative to the position in FIG. 8 after bridging a maximum adjustment a maximum adjustable distance a1 between the top 8 of the drawer rail 9 and the end 10a of the drawer 10 is set up.

For defined vertical relative movement of the housing 2 with respect to the tilt adjustment lever 5 or the adjusting wedge 4, a vertical guide groove 28 is formed in the installed state of the adjusting device 1 on the drawer on the tilt adjustment lever 5. In the guide groove 28 engages a guide web 29, which is configured on the inside of the housing 2, a (see in particular FIG. 5 and FIG. 15 ).

For an even better support of the adjusting wedge 4 on the upper side 8 of the drawer rail 9, the pull-wedge 6 can be detachably latched or clamped with a receptacle 31 on a downwardly projecting pin 30 at the connecting end 7 of the adjusting wedge 4, so that the pulling wedge 6 engages Extension of the sliding on the top 8 underside of Verstellkeils 4 forms what FIG. 12 shows schematically.

Furthermore, in particular FIGS. 13 and 14 the interaction of the tooth portion 3 a, which here for example comprises 6 teeth, with the counter tooth portion 26 in the opening 25 of the adjusting wedge 4.

FIG. 12 shows an adjustment with the Verstellritzel 3 between two possible end positions, with two teeth of the tooth portion 3a are supported on two teeth of the counter-tooth portion 26. In an end position according to FIG. 14 It is particularly advantageous in terms of damage or a breakage or failure of teeth on the mating tooth portion 26 and the tooth portion 3a, that the teeth 32 to 35 of the tooth portion 3a on the mating tooth portion 26 and on teeth 36, 37 and 38 of the mating tooth portion 26 can support.

FIG. 16 and FIG. 17 show highly schematized and not to scale a drawer 39 with a front part 40 which is slidably mounted on a guide unit 41 with a drawer rail on a furniture body, not shown. In addition, a connecting section 42, which is shown in a semicircular form and which supports the front of the underside of the drawer 39 with the guide unit 41, is also shown in highly schematic form. Furthermore, in the rear area of the drawer 39 or in a rear end area of the drawer 39 facing away from the front part 40, a double wedge arrangement 43 acts. The double wedge arrangement 43 functions according to the operating principle of the adjusting device 1 according to FIGS FIGS. 1 to 15 ,

Moreover, in the FIGS. 16 and 17 a vertical S indicated.

The double wedge assembly 43 includes a front wedge gear 44 and a rear wedge gear 45. Each wedge gear 44 and 45 includes an upper wedge surface 44a and 45a, which are associated with the drawer 39 and z. B. each attached to a drawer frame 39a or drawer side wall. The wedge surfaces 44a and 45a is associated with a cooperating wedge surface 44b and 45b, respectively, so that the co-operating inclined surfaces 44a and 44b or 45a and 45b slide against each other when on the Double wedge assembly 43 is acted upon.

A special feature is that the inclination of the wedge surfaces 44a and 44b is the same, here z. B. inclined by α1 of about 9 degrees to the guide unit 41, but differs from the inclination of the wedge surfaces 45a, 45b, whose inclination is also equal to each other. The wedge surfaces 45a, 45b have an inclination relative to the guide unit 41, whose angle α2 relative to the upper side 41a is approximately 14 degrees, for example.

Starting from a setting according to FIG. 16 , By adjusting the double wedge assembly 43, the inclination of the front part 40 relative to the vertical S in the in FIG. 17 changed position shown. Advantageously, almost no adjustment takes place in the horizontal direction of the drawer 39 or in the longitudinal direction of the guide unit 41. This is particularly clear from the distance S1 of the lower end of the front part 40 to the front end of the guide unit 41 in comparison to the distance S2 in FIG FIG. 17 , <U> REFERENCE LIST: </ u> 1 adjustment 43 Double wedge arrangement 2 casing 44a, 44b wedge surface 3 Verstellritzel 45a, 45b wedge surface 3a tooth portion 44, 45 spline gear 4 adjusting wedge 5 Neigungsverstellhebel 5a web 6 Zugkeil 7 connecting end 8th top 9 drawer rail 10 drawer 10a The End 11 - 14 slide nose 11a, 12a notch 15, 16 guideway 17 tooth portion 18, 19 guideway 20 wedge portion 21 sliding surface 22, 23 Long hole 24 midsection 25 opening 26 Against tooth portion 27 support surface 28 guide 29 guide web 30 spigot 31 admission 32 - 35 tooth 36 - 38 increase 39 drawer 39a drawer 40 front part 41 Guide unit 41a top 42 connecting portion
