Description

[0001] The present invention relates to a suspension device for suspending a piece of furniture on a wall according to the preamble of claim 1.

[0002] Suspension devices of this type are known, for example, from EP 1 362 531 A1, EP 3 328 245 B1 and EP 3 111 802 D1. Such suspension devices essentially consist of a suspension element, in particular a hook or a hook strip, and an adjustable support unit on which or into which the suspension element engages.

[0003] In the first-mentioned document, the suspension element, designed as a hook, is specified on a rear wall of the furniture, and the adjustable support unit is specified on a wall, in particular on a building wall.

[0004] In the second printed publication, the adjustable support unit, equipped with a hook, is attached to a piece of furniture to be hung, with the hook being hooked onto a horizontally extending support rail attached to the wall.

[0005] The adjustable support unit typically has two adjustment devices, with a first adjustment unit serving to adjust the furniture relative to the wall in its vertical orientation, while the second adjustment unit serving to adjust the distance between the back of the furniture and the wall.

[0006] This is particularly helpful during the hanging process of the furniture, where the back of the furniture should not touch the wall during alignment by adjusting the adjustment units, in order to prevent scratches on the wall or the back of the furniture.

[0007] The known suspension devices have proven their worth in practice.

[0008] The object of the present invention is to further develop a generic suspension device for suspending a piece of furniture on a wall in such a way that its construction is further simplified.

[0009] The problem is solved by a suspension device for suspending a piece of furniture on a wall with the features of claim 1.

[0010] The suspension device according to the invention has a wall bracket that can be attached to the wall and a body hook that can be fixed to the furniture wall of the furniture.

[0011] A support unit is arranged on the wall bracket.

[0012] The carrying unit has a hook receptacle into which the body hook can be inserted.

[0013] The support unit further comprises a first adjustment device for adjusting the hook receptacle in a vertical direction and a second adjustment device for adjusting a distance of the hook receptacle from the end bearing in a direction perpendicular to the vertical direction.

[0014] The support unit further features an adjustment strip that can be pivoted on the wall bearing and a slider that can be moved along the adjustment strip.

[0015] Furthermore, the adjusting strip has at least a fork-shaped contour which, engaging in a recess in the wall bearing, forms a pivot axis for pivoting the adjusting strip relative to the wall bearing.

[0016] With such a suspension device designed according to the invention, a simplified construction of such a suspension device is made possible compared to the receiving devices [in the first] prior art.

[0017] The fork-shaped contour on the adjustment bar makes it possible to save on a swivel axis designed as a separate component, for example in the form of a rivet or a rotary cylinder.

[0018] Advantageous embodiments of the invention are the subject of the dependent claims.

[0019] According to one embodiment of the invention, at least one recess in the wall bearing is provided in a bend of the wall bearing projecting towards the adjustment strip.

[0020] Such a bend can be easily incorporated into a wall support, preferably consisting essentially of a retaining plate.

[0021] The bend in the wall bearing is preferably U-shaped, trapezoidal or semicircular in cross-section.

[0022] All of the listed geometric designs of the bends can be easily incorporated into the wall bearing.

[0023] The at least one recess is preferably slot-shaped, with the slot extending perpendicular to the pivot axis.

[0024] The slot-shaped design also allows for precise adjustment of the adjustment strip in a direction parallel to the wall bearing.

[0025] According to an advantageous further development, an end-face edge of the recess forms a support defining the pivot axis of the fork-shaped contour of the adjustment strip.

[0026] According to another advantageous design variant, the adjusting strip has a base surface with edge ribs bent at right angles along its longitudinal sides.

[0027] At the lower end of these edge ribs, a fork-shaped contour is formed.

[0028] According to a further advantageous embodiment, the first adjusting device is designed as a bevel gear drive, with an adjusting wheel received in a bearing receptacle of a base surface of the slide, an adjusting screw held in a sliding but rotatable position and a retaining web fixed to the adjusting bar with a threaded bore in which a threaded section of the adjusting screw is received.

[0029] This allows for a simple vertical displacement of the slider relative to the adjustment bar and thus also relative to the wall bearing by turning the adjusting wheel.

[0030] According to another preferred embodiment, the second adjusting device has an adjusting screw which is held securely in a pivotable position in the slide by means of a threaded section.

[0031] A head of this adjusting screw is slidably held in an undercut elongated hole of the wall bearing, wherein an end of the adjusting screw facing away from the head has a tool receptacle for adjusting the adjusting screw, which is accessible through an opening in the base surface of the slider.

[0032] The accessibility of the tool holder of the adjusting screw allows both the first and second adjustment devices to be easily fine-tuned from the same side after the furniture has been hung.

[0033] According to another advantageous design variant, perpendicularly bent edge webs are also provided along the longitudinal sides of the base surface of the slide to guide the slide along the adjustment strip.

[0034] The shaping of these edge ribs provides a simple way to guide the slider along the adjustment bar in a vertical direction.

[0035] To prevent the adjusting strip from lifting off after the fork-shaped contours are inserted into the recesses in the wall bearing, bending webs are provided above the bending of the wall bearing according to a preferred embodiment of the invention, which are bent into a corresponding slot in the base surface of the adjusting strip after the adjusting strip has been inserted.

[0036] According to another advantageous design variant, a slot is formed on the base plate of the wall bearing in a symmetrical arrangement on both the left and right sides, on which the support unit can be arranged.

[0037] Due to its symmetrical geometry, the wall bearing can be used as both a left and a right part.

[0038] By using a suspension device as described above for hanging a piece of furniture on a wall according to the invention, simple hanging and alignment of the furniture is possible with a suspension device that is also simply constructed.

[0040] In the following figure descriptions, terms such as top, bottom, left, right, front, back, etc., refer exclusively to the exemplary representation and position of the suspension device, wall bracket, furniture, adjustment mechanisms, adjustment strip, slider, and the like as chosen in the respective figures. These terms are not to be understood restrictively; that is, these references may change due to different working positions, mirror-symmetrical design, or similar factors.

[0041] In the Figures 1 to 3 Reference numeral 1 designates a variant embodiment of a suspension device according to the invention.

[0042] The suspension device 1 serves, as shown in the Figures 1-3The illustration shows the suspension of a piece of furniture 9 on a wall 10. The piece of furniture 9 consists of side walls 91, a base, a top, a front cover (not shown) and a back wall 92, on which recesses 93 and 94 are arranged to allow access for tools and components of the suspension device 1.

[0043] The suspension device 1 has, as shown in detail in the exploded view according to Figure 7 The illustration shows a wall support 2 that can be arranged on the wall 10.

[0044] The wall bracket 2, attached to wall 10, is in Figure 2 as in Figure 4 The wall bracket 2 is preferably attached to the wall 10 by means of a screw connection with several screws 11, which are received in corresponding receptacles in the wall bracket 2.

[0045] The suspension device 1 also has a body hook 3 that can be fixed to the side wall 91 of the furniture 9.

[0046] The body hook 3 consists of the in Figures 2 to 4 and 7 The illustrated embodiments essentially consist of a fastening plate 32 which can be fixed to the side wall 91 of the furniture 9 and which is preferably screwed into a furniture wall 91 of the furniture 9 designed as a side wall using screws 13 and expanding sleeves 12.

[0047] From the mounting plate 32 extends a bend 33, which in a first section extends approximately parallel to a rear wall 92 of the furniture 9, or approximately parallel to the wall support 2, and in a second section is bent in such a way that it is aligned perpendicularly to the wall support 2.

[0048] In the part of the bend 33 oriented perpendicular to the wall 10, a recess 31 is provided which can be inserted into a hook receptacle 52 of a support unit for fastening the furniture 9.

[0049] The support unit of the suspension device 1 has an adjustment bar 4 which is pivotably arranged relative to the wall bearing 2 about a pivot axis S extending in a direction y and a slider 5 which is slidably held on the adjustment bar 4.

[0050] In the preferred embodiment shown, the hook receptacle 52 for attaching the body hook 3 is integrally formed on the slider 5.

[0051] The support unit further comprises a first adjusting device 6 for adjusting the hook receptacle 52 in a vertical direction z and a second adjusting device 7 for adjusting a distance d of the hook receptacle 52 from the wall bearing 2 in a direction x perpendicular to the vertical direction z.

[0052] The pivoting movement of the adjusting bar 4 always results in a slight adjustment in the vertical direction when adjusting the second adjusting device 7, although this adjustment is extremely small at the pivoting angles considered.

[0053] The adjusting strip 4 has at least one fork-shaped contour 43 which engages in a recess 23 in the wall bearing 2 and forms a pivot axis S for pivoting the adjusting strip 4 relative to the wall bearing 2.

[0054] The adjusting strip 4 further has a base surface 41, an elongated hole 45, two receptacles 44 and right-angled bent edge webs 42 adjoining the base surface 41, arranged on its longitudinal sides, at the edges of which fork-shaped contours 43 are formed.

[0055] In the embodiment of the suspension device 1 shown here, the wall bracket 2 has a total of four such recesses 23.

[0056] As in Figure 4 As shown, two such suspension devices 1 are preferably used to suspend the furniture 9, the body hooks 3 of which are fixed to the respective right and left furniture walls 91 designed as side walls.

[0057] The wall support 2 is dimensioned in its width, viewed in a direction y, such that the load transfer into the wall 10 is distributed over as wide an area as possible.

[0058] In principle, a wall support 2 is also conceivable which is reduced in width by about half, with correspondingly only two recesses 23 for receiving the two fork-shaped contours 43 on the edge webs 42 of the adjustment strip 4.

[0059] What next in the Figures 5 to 7As shown, the recesses 23 of the wall support 2 are preferably provided in a bend 22 of the wall support 2 projecting towards a base plate 21 of the wall support 2, which is oriented in a direction towards the adjusting strip 4.

[0060] The bend 22 of the wall support 2 is preferably U-shaped, trapezoidal, or semicircular in cross-section to facilitate the simplest possible placement of the fork-shaped contour 43 of the adjusting strip 4 onto an edge of the recess 23. The edge of the recess 23 rests on a transition section between the prongs of the fork.

[0061] The recesses 23 are preferably slot-shaped, with the slot extending perpendicular to the pivot axis S. The length of the slot-shaped recesses 23 is dimensioned such that one of the tines of the fork of the fork-shaped contour 43 can immerse in the recess and, in the immersed state, can pivot through a predetermined angle.

[0062] The pivot axis S is defined by an end-face edge of the recess 23, which serves as a support for the fork-shaped contour 43 of the adjustment strip, as is particularly evident in Figure 9C It is clearly visible.

[0063] The first adjusting device 6 and the second adjusting device 7 are in their individual parts in Figure 7 depicted.

[0064] The operation of the two adjustment devices 6, 7 is explained below using the following: Figures 8-11 described.

[0065] The first adjusting device 6 is preferably designed as a bevel gear drive, with an adjusting wheel 62 received in a hook receptacle 52 of a base surface 51 of the slide, and an adjusting screw 61 held on the slide 5 in a sliding-resistant but rotatable manner, having a head meshing with the adjusting wheel 62, and a retaining web 63 fixed to the adjusting bar 4 by means of the receptacles 44, having a threaded bore in which a threaded section of the adjusting screw 61 is received. A tool receptacle is integrally formed on the adjusting wheel 62 to also enable adjustment of the first adjusting device 6 by means of this, by allowing a tool to be inserted into the recess 94 of the rear wall 92.

[0066] The first adjustment device 6 enables, as particularly in comparison to the Figures 8C and 11C This illustrates a movement of the slider 5 along the adjustment bar 4 in the direction of the longitudinal extension of the adjustment bar 4.

[0067] The second adjusting device 7 of the support unit has an adjusting screw 71 which is held in a sliding-resistant position by a threaded section in a retaining element 72 held on the slide 5, wherein a rotational movement of the adjusting screw 71 causes the retaining element 72 and the slide 5 to pivot.

[0068] A head piece 73 of the adjusting screw 71 is held tiltably in an undercut elongated hole 24 of the wall bearing 2.

[0069] An end of the adjusting screw 71 facing away from the head piece 73 has a tool receptacle 74 accessible through an opening 54 in the base surface 51 of the slide 5 for adjusting the adjusting screw 71.

[0070] The effect of adjusting this second adjusting device 7 is well illustrated in a comparison of the Figures 8C and 9C recognizable.

[0071] The Figures 8A , 9A , 10A and 11Ashow a front view of the wall-side assembly of the suspension device 1, consisting of wall bracket 2, adjustment strip 4 and slider 5.

[0072] The Figures 8B , 9B , 10B and 11B show a side view and the Figures 8C , 9C , 10C and 11C a sectional view through a vertical section plane that is placed through the adjusting screw 61 and 71 of the respective adjusting device 6,7.

[0073] The Figures 8A to C show a starting position of the respective wall assembly, in which the adjusting screw 61 is in its lowest position and thus the slider 5 is in a lowest position relative to the adjusting bar 4.

[0074] The adjusting screw 71 of the second adjusting device 7 is also in a starting position in which the distance d between the hook receptacle 52 on the slide 5 and the wall bearing 2 is minimal.

[0075] In this position, the adjustment strip 4 extends parallel or almost parallel to the wall bearing 2.

[0076] The Figures 10A to C show a position of the wall assembly in which no height adjustment was made, but in which the adjusting screw 71 of the second adjusting device 7 was adjusted so that the adjusting bar 4 together with the slider 5 is positioned in a position pivoted to the maximum relative to a vertical.

[0077] The Figures 11A to C show an adjusted position of the assembly of the suspension device 1, in which the adjusting screw 71 of the second adjusting device 7 is in the Figures 8A to C the position shown and only the adjusting screw 61 of the first adjusting device 6 has been moved to its maximum adjustment position.

[0078] Adjusting the adjusting screw 61 of the first adjusting device 6 causes the slider 5 to shift along the adjusting bar 4, so that the slider 5 is positioned relative to the adjusting bar 4, as shown by a comparison of the Figures 8B with the Figure 11B illustrates that it is positioned in a maximally upward-shifted position.

[0079] The Figures 9A to C show a combination of the adjustments of the first adjusting device 6 and that of the second adjusting device 7, such that in this position both the adjusting screw 61 of the first adjusting device 6 and the adjusting screw 71 of the second adjusting device 7 were moved into a maximum adjustment position.

[0080] It can also be seen that when slider 5 is raised to its maximum position, the swivel angle is different compared to slider 5 when its height is not adjusted, as shown in the Figure 10 B and C as shown, is somewhat less than in the Figures 9B and Cshown swivel position of the adjusting bar 4 and the slider 5.

[0081] Advantageously, the first and second adjustment devices can be adjusted in a direction parallel to the extension of the side wall 91 of the furniture 9, in that the tool holders on the adjusting screw 71 and adjusting wheel 62 are facing the user and recesses 93, 94 are provided in the furniture.

[0082] To guide the slide 5 along the adjusting bar 4, the slide 5 also has perpendicularly bent edge webs 55 along the longitudinal sides of the base surface 51. Furthermore, a bearing receptacle 53 is formed on the base surface 51, which allows access to the tool receptacle of the adjusting wheel 62.

[0083] To prevent the adjusting strip 4 from lifting off after the fork-shaped contours have been inserted into the recesses 23 in the wall bearing 2, webs 25 are provided above the bend 22 of the wall bearing 2, which are bent into a corresponding slot 46 in the base surface 41 of the adjusting strip 4 after the adjusting strip 4 has been inserted.

[0084] What next in the Figures 8 to 12 As can be seen, with the exception of the respective cabinet hook 3, all other components of the suspension device, in particular the wall bracket 2, the two adjustment strips 4 and the slider 5, are symmetrically constructed. Specifically, two elongated holes 24 are arranged on the base plate 21 of the wall bracket 2 for this purpose, thus creating a symmetrical component.

[0085] This makes it possible to use only different cabinet hooks 3 for a hanging device 1 to be attached to the left side of the furniture 9 or to the right side of the furniture 9.

[0086] The wall bracket 2, the adjustment strip 4 and the slider 5 can therefore be used on both the right and left sides. Reference symbol list
