Abstract
Description
[0001] The present invention relates to a hanging device for hanging 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 and EP 3 111 802 D1.
[0003] Such suspension devices essentially consist of a suspension element, such as a hook or a hook rail, and an adjustable support unit on or into which the suspension element engages.
[0004] In the first-mentioned document, the suspension element designed as a hook is fixed to a rear wall of the furniture and the adjustable support unit is fixed to a wall, in particular to a building wall.
[0005] In the second publication, the adjustable support unit provided with a hook is attached to a piece of furniture to be suspended, the hook being hooked onto a horizontally extending support bar attached to the wall.
[0006] The adjustable support unit typically has two adjustment devices, a first adjustment unit being used to adjust the furniture relative to the wall in its vertical alignment, while the second adjustment unit is used to adjust the distance between the back of the furniture and the wall.
[0007] This is particularly helpful when hanging the furniture, where the back of the furniture should not touch the wall while aligning by adjusting the adjustment units in order to prevent scratches on the wall or the back of the furniture.
[0008] The well-known suspension devices have proven themselves in practice.
[0009] The object of the present invention is to further develop a generic hanging device for hanging a piece of furniture on a wall in such a way that its construction is further simplified.
[0010] The stated object is achieved by a hanging device for hanging a piece of furniture on a wall having the features of claim 1.
[0011] The suspension device according to the invention has a wall bearing that can be attached to the wall and a body hook that can be fixed to the wall of the furniture.
[0012] A support unit is arranged on the wall bearing.
[0013] The carrying unit has a hook holder into which the body hook can be hooked.
[0014] The support unit further comprises a first adjusting device for adjusting the hook receptacle in a vertical direction and a second adjusting device for adjusting a distance of the hook receptacle from the end bearing in a direction perpendicular to the vertical direction.
[0015] The support unit also has an adjustment bar that can be pivoted on the wall bearing and a slider that is slidably held on the adjustment bar.
[0016] Furthermore, the adjustment bar has at least one fork-shaped contour which, engaging in a recess in the wall bearing, forms a pivot axis for pivoting the adjustment bar relative to the wall bearing.
[0017] With such a suspension device designed according to the invention, a simplified construction of such a suspension device is possible compared to the receiving devices [in the first] prior art.
[0018] The fork-shaped contour on the adjustment bar makes it possible to eliminate the need for a swivel axis designed as a separate component, for example in the form of a rivet or a rotary cylinder.
[0019] Advantageous embodiments of the invention are the subject of the subclaims.
[0020] According to a variant of the invention, the at least one recess in the wall bearing is arranged in a bend of the wall bearing that projects towards the adjustment bar.
[0021] Such a bend can be easily inserted into a wall bearing, preferably consisting essentially of a holding plate.
[0022] The bend of the wall bearing is preferably U-shaped, trapezoidal or semicircular in cross section.
[0023] All of the listed geometric designs of the bends can be easily incorporated into the wall bearing.
[0024] The at least one recess is preferably slot-shaped, wherein the slot extends perpendicular to the pivot axis.
[0025] The slot-shaped design also enables a concrete adjustment of the adjustment bar in a direction parallel horizontally to the wall bearing.
[0026] According to an advantageous further development, a front edge of the recess forms a support of the fork-shaped contour of the adjustment bar, defining the pivot axis.
[0027] According to a further advantageous embodiment, the adjustment strip has a base surface with edge webs bent at right angles along its long sides.
[0028] At the lower end of each of these edge bars, a fork-shaped contour is formed.
[0029] According to a further advantageous embodiment, the first adjusting device is designed as a bevel gear, with an adjusting wheel received in a bearing receptacle of a base surface of the slide, a sliding-resistant but rotatably held adjusting screw and a holding web fixed to the adjusting bar with a threaded bore in which a threaded section of the adjusting screw is received.
[0030] This allows 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.
[0031] According to a further preferred embodiment, the second adjusting device has an adjusting screw which is held in a sliding-proof manner by means of a threaded section in a holding element which is pivotably held in the slide.
[0032] A head piece of this adjusting screw is held displaceably in an undercut slot in the wall bearing, with an end of the adjusting screw facing away from the head piece having a tool holder for adjusting the adjusting screw, which is accessible through an opening in the base surface of the slide.
[0033] Thanks to the accessibility of the tool holder for the adjusting screw, both the first and the second adjustment device can be easily adjusted from the same side for fine adjustment after the furniture has been hung up.
[0034] According to a further advantageous embodiment, edge webs bent at right angles are also provided along the long sides of the base surface of the slider to guide the slider along the adjustment bar.
[0035] The formation of these edge webs makes it easy to guide the slider along the adjustment bar in the vertical direction.
[0036] In order to prevent the adjustment bar from lifting off after the fork-shaped contours have been inserted into the recesses in the wall bearing, according to a preferred development of the invention, bending webs are provided above the bend of the wall bearing, which, after the adjustment bar has been inserted, are bent into a corresponding slot in the base surface of the adjustment bar.
[0037] According to a further advantageous embodiment, an elongated hole is formed on the base plate of the wall bearing in a symmetrical arrangement on the left and right sides, on which the support unit can be arranged.
[0038] Due to its symmetrical geometry, the wall bearing can be used as both a left-hand and right-hand part.
[0039] The inventive use of a hanging device as described above for hanging a piece of furniture on a wall provides for simple hanging and alignment of the furniture while at the same time providing a simply constructed hanging device.

[0041] In the following description of the figures, terms such as top, bottom, left, right, front, back, etc., refer exclusively to the exemplary representation and position of the suspension device, wall mount, furniture, adjustment devices, adjustment bar, slider, and the like chosen in the respective figures. These terms are not to be understood as limiting; i.e., these references may change due to different working positions or mirror-symmetrical design, etc.
[0042] In the Figures 1 to 3 Reference number 1 designates a variant of a suspension device according to the invention.
[0043] The suspension device 1 serves, as shown in the Figures 1-3is shown, 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 panel, a front cover (not shown) and a rear wall 92, on which recesses 93 and 94 are arranged to allow access to tools and components of the suspension device 1.
[0044] The suspension device 1 has, as shown in detail in the exploded view according to Figure 7 shown, a wall bearing 2 which can be arranged on the wall 10.
[0045] The wall bearing 2 attached to the wall 10 is in Figure 2 as well as in Figure 4 The wall support 2 is preferably attached to the wall 10 by means of a screw connection with several screws 11, which are inserted into the recesses provided for this purpose in the wall support 2.
[0046] The suspension device 1 further comprises a body hook 3 that can be fixed to the side wall 91 of the furniture 9.
[0047] The body hook 3 consists of the Figures 2 to 4 and 7 illustrated embodiments essentially consists of a fastening plate 32 which can be fixed to the side wall 91 of the piece of furniture 9 and which is preferably screwed into a furniture wall 91 of the piece of furniture 9 designed as a side wall using screws 13 and expansion sleeves 12.
[0048] A bend 33 extends from the fastening plate 32, which in a first section extends approximately parallel to a rear wall 92 of the furniture 9, or approximately parallel to the wall bearing 2, and in a second section is bent such that it is aligned perpendicular to the wall bearing 2.
[0049] In the part of the bend 33 oriented perpendicular to the wall 10, a recess 31 is provided, which can be hooked into a hook receptacle 52 of a support unit for fastening the furniture 9.
[0050] The support unit of the suspension device 1 has an adjustment bar 4 which is arranged to be pivotable relative to the wall bearing 2 about a pivot axis S extending in a direction y and a slider 5 which is displaceably held on the adjustment bar 4.
[0051] In the preferred embodiment shown, the hook receptacle 52 for hanging the body hook 3 is formed on the slider 5.
[0052] 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.
[0053] Due to the pivoting movement of the adjustment bar 4, adjustment of the second adjustment device 7 always results in a slight adjustment in the vertical direction, which, however, is extremely small for the pivoting angles considered.
[0054] The adjustment bar 4 has at least one fork-shaped contour 43 which, engaging in a recess 23 in the wall bearing 2, forms a pivot axis S for pivoting the adjustment bar 4 relative to the wall bearing 2.
[0055] The adjustment strip 4 further comprises a base surface 41, an elongated hole 45, two receptacles 44 and edge webs 42 which are arranged at right angles to the base surface 41 and are arranged on the edge side of the longitudinal sides thereof, and at the lower ends of which such fork-shaped contours 43 are formed.
[0056] In the embodiment of the suspension device 1 shown here, the wall bearing 2 has a total of four such recesses 23.
[0057] 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 respective right and left furniture walls 91 designed as side walls.
[0058] The width of the wall bearing 2, viewed in a direction y, is dimensioned such that the load transfer into the wall 10 is distributed over as wide an area as possible.
[0059] In principle, a wall bearing 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.
[0060] How to continue in the Figures 5 to 7As shown, the recesses 23 of the wall bearing 2 are preferably made in a bend 22 of the wall bearing 2 projecting towards a base plate 21 of the wall bearing 2, which is aligned in a direction towards the adjustment bar 4.
[0061] The bend 22 of the wall bearing 2 is preferably U-shaped, trapezoidal, or semicircular in cross-section, in order to enable the fork-shaped contour 43 of the adjustment strip 4 to be placed as easily as possible on an edge of the recess 23. The edge of the recess 23 rests on a transition section between the tines of the fork.
[0062] The recesses 23 are preferably slot-shaped, wherein the slot extends 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 dip into the recess and, in the dipped state, can be pivoted by a predetermined angle.
[0063] The pivot axis S is defined by a front edge of the recess 23, which serves as a support for the fork-shaped contour 43 of the adjustment bar, as is particularly the case in Figure 9C is clearly visible.
[0064] The first adjusting device 6 and the second adjusting device 7 are in their individual parts in Figure 7 shown.
[0065] The functioning of the two adjustment devices 6,7 is explained below using the Figures 8-11 described.
[0066] The first adjusting device 6 is preferably designed as a bevel gear, with an adjusting wheel 62 received in a hook receptacle 52 of a base surface 51 of the slide, and with an adjusting screw 61 held on the slide 5 in a sliding-resistant but rotatable manner, having a head that meshes with the adjusting wheel 62 and a holding web 63 that is fixedly attached to the adjusting bar 4 by means of the receptacles 44 and has a threaded bore in which a threaded portion of the adjusting screw 61 is received. A tool holder is formed on the adjusting wheel 62 in order to also enable adjustment of the first adjusting device 6 by inserting a tool into the recess 94 of the rear wall 92.
[0067] The first adjustment device 6 enables, as can be seen particularly in comparison with the Figures 8C and 11C is illustrated, a displacement of the slider 5 along the adjustment bar 4 in the direction of the longitudinal extent of the adjustment bar 4.
[0068] The second adjustment device 7 of the support unit has an adjusting screw 71 which is held in a sliding-proof manner by means of a threaded section in a holding element 72 held on the slide 5, wherein a rotational movement of the adjusting screw 71 causes a pivoting of the holding element 72 and the slide 5.
[0069] A head piece 73 of the adjusting screw 71 is held in an undercut slot 24 of the wall bearing 2 so that it can be tilted.
[0070] An end of the adjusting screw 71 facing away from the head piece 73 has a tool holder 74 accessible through an opening 54 in the base surface 51 of the slide 5 for adjusting the adjusting screw 71.
[0071] The effect of an adjustment of this second adjustment device 7 is well shown in a comparison of the Figures 8C and 9C recognizable.
[0072] The Figures 8A , 9A , 10A and 11Ashow a front view of the wall-side assembly of the suspension device 1, consisting of wall bearing 2, adjustment bar 4 and slider 5.
[0073] 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 cutting plane passing through the adjusting screw 61 and 71 of the respective adjusting device 6,7.
[0074] 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 adjustment bar 4.
[0075] The adjusting screw 71 of the second adjusting device 7 is also in an initial position in which a distance d between the hook receptacle 52 on the slide 5 and the wall bearing 2 is minimal.
[0076] In this position, the adjustment bar 4 extends parallel or almost parallel to the wall bearing 2.
[0077] The Figures 10A to C show a position of the wall assembly in which no height adjustment was carried out, but in which the adjusting screw 71 of the second adjustment device 7 was adjusted so that the adjustment bar 4 together with the slider 5 are positioned in a position pivoted to the maximum relative to a vertical.
[0078] 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 position shown in the Figures 8A to C shown position and only the adjusting screw 61 of the first adjusting device 6 has been moved to its maximum adjustment position.
[0079] The adjustment of the adjusting screw 61 of the first adjusting device 6 is accompanied by a displacement of the slide 5 along the adjusting bar 4, so that the slide 5 relative to the adjusting bar 4, as a comparison of the Figures 8B with the Figure 11B As shown, it is positioned in a position that is maximally shifted upwards.
[0080] The Figures 9A to C show a combination of the adjustments of the first adjustment device 6 and the second adjustment device 7, so that in this adjustment position both the adjusting screw 61 of the first adjustment device 6 and the adjusting screw 71 of the second adjustment device 7 were moved into a maximum adjustment position.
[0081] It can also be seen that when the slider 5 is moved to its maximum height, the swivel angle is smaller than when the slider 5 is not adjusted in height, as shown in the Figure 10 B and C shown, is slightly lower than in the Figures 9B and Cshown pivoting position of the adjustment bar 4 and the slider 5.
[0082] Advantageously, an adjustment possibility of the first and the second adjustment device in a direction parallel to the extension of the side wall 91 of the furniture 9 is provided in that the tool holders on the adjusting screw 71 and adjusting wheel 62 face the user and recesses 93, 94 are introduced into the furniture.
[0083] To guide the slider 5 along the adjustment bar 4, the slider 5 also has edge webs 55 bent at right angles along the long sides of the base surface 51. Furthermore, a bearing receptacle 53 is formed on the base surface 51, which allows access to the tool holder of the adjusting wheel 62.
[0084] To prevent the adjustment bar 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 webs are bent into a corresponding slot 46 in the base surface 41 of the adjustment bar 4 after the adjustment bar 4 has been inserted.
[0085] How to continue in the Figures 8 to 12 As can be seen, with the exception of the respective body hook 3, all other components of the suspension device, in particular the wall mount 2, the two adjustment bars 4, and the slider 5, are constructed symmetrically. For this purpose, two elongated holes 24 are arranged on the base plate 21, particularly on the wall mount 2, in order to create a symmetrical component.
[0086] This makes it possible for only different body hooks 3 to be used for a suspension device 1 to be attached to the left side of the furniture 9 or to the right side of the furniture 9.
[0087] The wall bearing 2, the adjustment bar 4 and the slider 5 can therefore be used on both the right and left sides. List of reference symbols
