Description

Suspension device The present invention relates to a suspension device for hanging a piece of furniture on a wall according to the preamble of claim 1. Typical suspension devices are known, for example, from documents EP 1362531 A1, EP 3328245 B1 and EP 3111802 D1. These suspension devices essentially consist of a suspension element, such as a hook or hook bar, and an adjustable support unit, on or to which the suspension element is attached. In the first document mentioned, the suspension element, designed as a hook, is attached to the back panel of the furniture, and the adjustable support unit is fixed to a wall, particularly a building wall. In the second document mentioned, the adjustable support unit, equipped with a hook, is attached to a piece of furniture to be hung, with the hook engaging a horizontal support rail fixed to the wall. The adjustable support unit typically features two adjustment mechanisms: one for vertically aligning the furniture with the wall, and the other for adjusting the distance between the back of the furniture and the wall. This is particularly useful during the furniture suspension process, as the back of the furniture should not touch the wall during alignment by adjusting the adjustment units, to avoid scratches on the wall or the back of the furniture. Known suspension devices have proven their effectiveness in practice. The objective of the present invention is to further develop a generic suspension device for hanging furniture on the wall, so that its construction is further simplified. The objective is achieved by means of a suspension device for hanging a piece of furniture on a wall with the characteristics of claim 1. The suspension device according to the invention features a wall bracket, which can be fixed to the wall, as well as a body hook, which can be fixed to the furniture wall. A support unit is arranged on the wall bracket. The support unit features a hook receptacle, into which the body hook can be inserted. The support unit also features a first adjustment device, for adjusting the hook receptacle in a vertical direction, and a second adjustment device, for adjusting the distance of the hook receptacle from the end bearing in a direction perpendicular to the vertical direction. The support unit also features an adjustment bar, pivotally mounted on the wall bracket, and a slider that can be slid along said adjustment bar. In addition, the adjustment bar has at least one fork-shaped contour which, when engaged in a receptacle of the wall bracket, forms a pivot axis, to pivot the adjustment bar with respect to the wall bracket. With a suspension device designed according to the invention, a simplified construction of said suspension device is achieved compared to the receiving devices [of the first] prior art. The fork-shaped contour of the adjustment bar allows for savings on a pivot shaft designed as a separate component, for example, in the form of a rivet or rotating cylinder. Advantageous embodiments of the invention are the subject of the dependent claims. According to one embodiment of the invention, at least one recess is provided in the wall bracket in a curve of the wall bracket, which projects towards the adjustment bar. This curvature can be easily incorporated into a wall bracket, preferably consisting essentially of a retaining plate. The curvature in the wall support preferably has a U-shaped, trapezoidal, or semicircular cross-section. All the listed geometric designs of the curves can be easily incorporated into the wall mount. Preferably, at least one of the recesses is groove-shaped, and this groove extends perpendicularly to the pivot axis. The grooved design also allows for precise adjustment of the adjustment bar in a direction parallel to the wall bracket. According to a further advantageous development, a front edge of the recess forms a support, which defines the pivot axis, of the fork-shaped contour of the adjustment bar. According to another advantageous embodiment, the adjustment bar has a base surface with ribs on the edges bent at right angles along its longitudinal sides. At the lower end of these edge ribs, a fork-shaped outline is formed. According to another advantageous embodiment, the first adjusting device is designed as a bevel gear mechanism, with an adjusting wheel housed in a bearing receptacle on the base surface of the slider, an adjusting screw held firmly so that it does not slide but rotate, and a retaining rib fixed stationarily to the adjusting bar with a threaded hole, in which a threaded section of the adjusting screw is housed. This allows for easy vertical movement of the slider relative to the adjustment bar and therefore also relative to the wall bracket, by turning the adjustment wheel. According to another preferred embodiment, the second adjustment device has a firmly held adjustment screw with a threaded section, so that it does not slide in the retaining element, which is pivotally held in the slider. The head piece of this adjusting screw is held slidingly in an elongated undercut hole in the wall bracket, so that one end of the adjusting screw facing outwards from the head piece features a tool receptacle, which allows the adjusting screw to be adjusted, which can be accessed through an opening in the base surface of the slider. The accessibility of the adjustment screw's tool receptacle allows both the first and second adjustment devices to be easily adjusted from the same side once the furniture is hung. According to another advantageous embodiment, right-angle bent edge ribs are also provided along the longitudinal sides of the slider's base surface to guide the slider along the adjustment bar. The shape of these edge ribs provides an easy way to guide the slider along the adjustment bar in a vertical direction. To prevent the adjustment bar from coming loose after the fork-shaped contours are inserted into the recesses of the wall bracket, bending ribs are provided above the curvature of the wall bracket according to a preferred development of the invention, which bend into a corresponding groove in the base surface of the adjustment bar, after the adjustment bar has been inserted. According to another advantageous embodiment, an elongated hole is formed in the base plate of the wall bracket in a symmetrical arrangement on both the left and right sides, onto which the support unit can be placed. Due to its symmetrical geometry, the wall mount can be used on either the left or right side. By using, according to the invention, a suspension device as described above to hang a piece of furniture on the wall, it is possible to hang and align the furniture easily with a suspension device, which is also of simple construction. Preferred exemplary embodiments of the invention are explained in more detail below, with reference to the accompanying drawings.

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, cabinet, adjustment devices, adjustment bar, slider, etc., as shown in the corresponding figures. These terms should not be interpreted restrictively; that is, these references may vary due to different working positions, symmetrical design, or similar factors. In Figures 1 to 3, reference number 1 designates a variant embodiment of a suspension device according to the invention. The suspension device 1 serves, in this case, as shown in Figures 1 to 3, to hang a piece of furniture 9 from a wall 10. In this case, the furniture 9 consists of side panels 91, a base, a top panel, a front cover (not shown) and a back panel 92, in which recesses 93 and 94 are arranged to allow access for tools and components of the suspension device 1. The suspension device 1 features, as shown in detail in the exploded view according to Figure 7, a wall bracket 2 that can be placed on the wall 10. The wall bracket 2, fixed to the wall 10, is shown in Figure 2, as well as in Figure 4. Preferably, the wall bracket 2 is fixed to the wall 10 by means of a screw connection with several screws 11, which are housed in the receptacles provided in the wall bracket 2. The suspension device 1 also features a body hook 3, which can be attached to the side panel 91 of the cabinet 9. In the exemplary embodiments depicted in Figures 2 to 4 and 7, the body hook 3 essentially consists of a fixing plate 32, which can be fixed to the side panel 91 of the furniture 9, and which is preferably screwed to a furniture panel 91 of the furniture 9, designed as a side panel, with screws 13 and expansion sleeves 12. From the fixing plate 32 extends a curve 33, which in a first section extends approximately parallel to a rear panel 92 of the cabinet 9, or approximately parallel to the wall bracket 2, and in a second section curves in such a way that it is aligned perpendicularly to the wall bracket 2. In the part of the curve 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, to fix the furniture 9. The suspension device support unit 1 features an adjustment bar 4 that is pivotally arranged with respect to the wall bracket 2 about a pivot axis S extending in a y direction, and a slider 5 slidably attached to the adjustment bar 4. In the preferred exemplary embodiment shown, the hook receptacle 52 for inserting the body hook 3 is integrally formed in the slider 5. The support unit further features a first adjustment device 6 for adjusting the hook receptacle 52 in a vertical z direction and a second adjustment device 7 for adjusting a distance d from the hook receptacle 52 from the wall support 2 in an x ​​direction perpendicular to the vertical z direction. The pivoting movement of the adjustment bar 4 always causes a slight adjustment in the vertical z direction when adjusting the second adjustment device 7, although this adjustment is extremely small at the pivot angles considered. The adjustment bar 4 has at least one fork-shaped contour 43 that engages in a recess 23 of the wall bracket 2 and forms a pivot axis S for pivoting the adjustment bar 4 with respect to the wall bracket 2. The adjustment bar 4 further features a base surface 41, an elongated hole 45, two receptacles 44, as well as right-angle bent edge ribs 42 adjacent to the base surface 41, arranged on the longitudinal sides of the edges, at whose lower ends the fork-shaped contours 43 are integrally formed. In the embodiment of the suspension device 1 shown here, the wall bracket 2 has a total of four of these recesses 23. As depicted in Figure 4, two of these suspension devices 1 are preferably used to hang the furniture 9, whose body hooks 3 are fixed to the respective right and left walls of the furniture 91 designed as side panels. The wall bracket 2 is dimensioned in its width, viewed from one direction, and in such a way that the load transfer to wall 10 is distributed over as wide an area as possible. In principle, a wall bracket 2 is also possible, which is reduced to half its width, with correspondingly only two recesses 23 to receive the two fork-shaped contours 43 in the edge ribs 42 of the adjustment bar 4. As further depicted in Figures 5 to 7, the recesses 23 of the wall bracket 2 are preferably arranged in a curve 22 of the wall bracket 2, which projects towards a base plate 21 of the wall bracket 2, which is oriented in a direction towards the adjustment bar 4. The curvature 22 of the wall bracket 2 preferably has a U-shaped, trapezoidal, or semicircular cross-section to facilitate the simplest possible placement of the fork-shaped contour 43 of the adjustment bar 4 on an edge of the recess 23. The edge of the recess 23 rests on a transition section between the fork tips. The recesses 23 are preferably groove-shaped, with the groove extending perpendicularly to the pivot axis S. The length of the groove-shaped recesses 23 is dimensioned so that one of the prongs of the fork-shaped contour 43 can be submerged in the recess and, in the submerged state, can pivot at a predetermined angle. The pivot axis S is defined, in this case, by a front edge of the recess 23, which serves as a support for the fork-shaped contour 43 of the adjustment bar, as can be seen particularly well in Figure 9C. Figure 7 shows, in their respective individual parts, the first adjustment device 6 and the second adjustment device 7. The operating mode of the two adjustment devices 6 and 7 is described below with reference to Figures 8 to 11. The first adjusting device 6 is preferably designed as a bevel gear mechanism, with an adjusting wheel 62 housed in a hook receptacle 52 on the base surface 51 of the slider, as well as an adjusting screw 61 firmly attached, so as not to slide but to rotate, to the slider 5, the head of which meshes with the adjusting wheel 62, and a retaining rib 63, fixed stationarily to the adjusting bar 4 by means of receptacles 44, with a threaded hole, in which a threaded section of the adjusting screw 61 is housed. A tool receptacle is integrally formed in the adjusting wheel 62, which allows the first adjusting device 6 to be adjusted as well, so that a tool can be inserted into the recess 94 of the rear panel 92. The first adjustment device 6 allows, as can be seen particularly in the comparison of Figures 8C and 11C, the slider 5 to slide along the adjustment bar 4 in the direction of the longitudinal extension of the adjustment bar 4. The second adjustment device 7 of the support unit features a firmly held adjustment screw 71, with a threaded section, so that it does not slip, in a retaining element 72 attached to the slider 5, such that a rotational movement of the adjustment screw 71 causes the retaining element 72 and the slider 5 to pivot. A head piece 73 of the adjusting screw 71 is tiltably held in an elongated undercut hole 24 of the wall bracket 2. One end of the adjusting screw 71 facing outwards from the headpiece 73 features a tool receptacle 74 accessible through an opening 54 in the base surface 51 of the slider 5, for adjusting the adjusting screw 71. The effect of adjusting this second adjustment device 7 can be clearly seen by comparing Figures 8C and 9C. Figures 8A, 9A, 10A and 11A show a front view of the wall-side assembly of the suspension device 1, consisting of a wall bracket 2, an adjustment rod 4 and a slider 5. Figures 8B, 9B, 10B and 11B show a side view and Figures 8C, 9C, 10C and 11C show a cross-sectional representation through a vertical section plane, which is placed through the adjusting screw 61 and 71 of the respective adjusting device 6, 7. Figures 8A to C show an initial position of the corresponding wall assembly, in which the adjusting screw 61 is in its lowest position and, therefore, the slider 5 is in a lower position relative to the adjusting bar 4. The adjusting screw 71 of the second adjusting device 7 is also in an initial position, where the distance d between the hook receptacle 52 on the slider 5 and the wall bracket 2 is at its minimum. In this position, the adjusting bar 4 extends parallel or nearly parallel to the wall bracket 2. 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 in such a way that the adjusting bar 4 together with the slider 5 is positioned in a pivoted position to the maximum with respect to a vertical. Figures 11A to C show an adjusted position of the suspension device assembly 1, in which the adjusting screw 71 of the second adjusting device 7 is in the position shown in Figures 8A to C and only the adjusting screw 61 of the first adjusting device 6 has been moved to its maximum adjustment position. Adjusting the adjusting screw 61 of the first adjusting device 6 causes the slider 5 to slide along the adjusting bar 4, so that the slider 5 is placed in a maximum upward offset position relative to the adjusting bar 4, as illustrated by a comparison with Figures 8B and 11B. Figures 9A to C show a combination of the settings of the first adjusting device 6 and the second adjusting device 7, so that in this adjusting 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 to a maximum adjusting position. Furthermore, it can be observed that when slider 5 is in its maximum upper position, the pivot angle is slightly less than in the pivot positions of adjustment bar 4 and slider 5, as shown in Figures 9B and C, compared to slider 5 not adjusted in height, as shown in Figures 10B and C. Advantageously, the first and second adjustment devices can be adjusted in a direction parallel to the extension of the side panel 91 of the cabinet 9, so that the tool receptacles on the adjustment screw 71 and the adjustment wheel 62 are oriented towards the user, and recesses 93 and 94 have been incorporated into the cabinet. To guide the slider 5 along the adjusting bar 4, the slider 5 also features right-angle bent edge ribs 55 along the longitudinal sides of the base surface 51. In addition, a bearing receptacle 53 is formed in the base surface 51, which allows access to the tool receptacle of the adjusting wheel 62. To prevent the adjustment bar 4 from lifting up after the fork-shaped contours have been inserted into the recesses 23 of the wall bracket 2, ribs 25 are provided above the bend 22 of the wall bracket 2, which bend into a corresponding groove 46 on the base surface 41 of the adjustment bar 4, after the adjustment bar 4 has been inserted. As can be seen in Figures 8 to 12, with the exception of the body hook 3, all other components of the suspension device, in particular the wall bracket 2, the two adjustment bars 4, and the slider 5, have a symmetrical construction. Specifically, this is achieved by providing two elongated holes 24 in the base plate 21 of the wall bracket 2, thus creating a symmetrical component. This allows the use of only different body hooks 3 for a suspension device 1, which is attached to the left side of the cabinet 9 or the right side of the cabinet 9. Therefore, the wall bracket 2, the adjustment bar 4, and the slider 5 can be used on both the right and left sides.
