Description

[0001] Suspension system and method for assembling a piece of furniture

[0002] The present invention relates to a suspension system for furniture, comprising a rail that can be fixed to a wall and has a retaining section, a furniture body with a top panel, a bottom panel and two side walls connecting the top panel to the bottom panel, at least two cabinet hangers fixed to the furniture body, each of which is suspended by a hook on the retaining section of the rail, and a fastening element arranged on a top side of the furniture body that is connected to the rail or is integrally formed with the rail, and a method for mounting a piece of furniture on a wall.

[0003] EP 2 745 739 B1 discloses a furniture suspension device in which a cabinet hanger is fixed to the back of a furniture carcass. This hanger is fixed to the carcass at one end and can be suspended from a rail, which is fixed to a wall, by means of a movable attachment point. The attachment point is movable relative to the furniture carcass for adjustment. Such cabinet hangers allow for the stable fixing of wall cabinets, especially when the fasteners on the rail are located in the area of ​​the cabinet hanger. However, in lightweight walls with posts arranged at regular intervals within the wall, the fasteners for fixing the rail may be positioned at a distance from the cabinet hangers, which can lead to stability problems under heavy loads.

[0004] EP 2 421 406 B1 discloses a cabinet bracket with a release mechanism. The cabinet bracket includes a hook that can be attached to a wall-mounted rail. Locking devices can be provided on the rail to limit lifting of the cabinet after installation. This prevents accidental release of the cabinet by lifting, but the problem remains that if the rail's fixings are too far from the cabinet hangers, stability issues can arise under heavy loads.

[0005] It is therefore an object of the present invention to provide a suspension system for furniture and a method for mounting furniture that ensure stable fixation of the furniture body to the wall. This object is achieved with a suspension system having the features of claim 1 or 13 and a method having the features of claim 14.

[0006] The furniture suspension system according to the invention comprises a rail with a retaining section that can be fixed to a wall, a furniture body with a top panel, a base, and two side walls connecting the top panel to the base, at least two cabinet hangers fixed to the furniture body, each of which is hooked onto the retaining section of the rail, and a fastening element arranged on the top of the furniture body, which is connected to or integrally formed with the rail, wherein the fastening element is fixed to the furniture body by at least one fastening means. The fastening element on the top of the furniture body thus not only provides protection against lifting the furniture body, but also a secure connection that improves the stability of the suspension.Especially when the furniture body is subjected to a high weight load, movement of the furniture body relative to the rail is limited or prevented by the fastening element, thus preventing the rail from detaching from the wall under heavy loads. This also compensates for unfavorable load conditions, for example, when the fasteners for fixing the rail to the wall are spaced apart along the length of the rail from the mounting hooks of the cabinet hanger, which can occur with lightweight walls featuring regularly spaced studs.

[0007] In a preferred embodiment, the rail has a hook-shaped retaining section. The hook-shaped section can be substantially U-shaped in cross-section, and the free end of the leg for attaching the mounting hook projects upwards. The hook-shaped retaining section is preferably located below mounting holes in the rail for wall fixing. This provides additional stabilization from the wall when, under heavy loads from the furniture body, a torque exerted on the rail in a direction away from the wall.

[0008] For particularly stable fixing of the furniture carcass, the rail can have an upper horizontal web that is integrally designed as a fastening element. The rail then rests with this upper horizontal web on a top surface of the furniture carcass, in particular on the top panel and / or an upper end edge of the side panel, and can be connected to the furniture carcass there by fasteners, for example, one or more screws. For this purpose, openings for the at least one fastener can be formed in the upper horizontal web, with the openings being spaced at regular intervals so that the number and position of the fasteners can be selected during installation. The upper horizontal web preferably extends over the entire length of the rail, so that after the rail is attached to the wall, one or more furniture carcasses can be suspended from the rail.

[0009] In an alternative embodiment, the rail has an upper horizontal rib to which a separate fastening element is attached. This separate fastening element can, for example, be designed as a rib that is hooked onto an opening in the upper horizontal rib. This reduces the material required for fixing the furniture carcass, as only one or more rib-shaped fastening elements need to be attached to the top of the furniture carcass, for example, using screws. The fastening element can be hooked into an opening in the upper horizontal rib, so that the fastening element is installed by inserting it into the opening and securing it to the top of the furniture carcass.

[0010] Alternatively, it is also possible to design the rail without the horizontal web and to fix the fastening device to a different section of the rail, for example to an upper bead.

[0011] For effective mounting, the cabinet hanger can have an adjustment mechanism that allows the height of the hook relative to the part of the hanger fixed to the cabinet body to be adjusted, particularly in terms of height and / or swivel. This allows the cabinet body to be hung on the mounting section of the rail via the hook, and after hanging, the cabinet body can be lifted using the adjustment mechanism before the mounting element is secured. The cabinet body is then also secured against being lifted from its mounted position. For stable fixing of the cabinet hanger, it can be screwed to a side panel of the cabinet body. For height adjustment, the rail preferably has several mounting holes in the form of elongated slots, which are inclined lengthwise to the horizontal. This allows for further height adjustments during installation.Preferably, at least one wall on one longitudinal side of the elongated hole is corrugated or has projections to secure the rail to mounting means for wall fixing, for example screws, and to prevent the rail from shifting. The opposite walls of the elongated hole preferably extend parallel to each other.

[0012] An alternative suspension system for furniture according to the invention comprises a rail with a mounting section that can be fixed to a wall, a furniture body with a top panel, a bottom panel, and two side panels connecting the top panel to the bottom panel, and at least two cabinet hangers fixed to the furniture body, each of which is hooked onto the mounting section of the rail by means of a hook. The wall-mountable rail has mounting openings for wall attachment located above the mounting section. This allows the rail, which runs continuously between the two cabinet hangers, to provide guidance when the hooks are attached to the mounting section, preferably by means of a vertical web in the rail. The rail thus allows recesses and unevenness in the wall to be bridged.Furthermore, this allows the leverage ratios to be optimized when forces act on the holding section and the rail is fixed to the wall using mounting devices such as screws.

[0013] In the inventive method for mounting furniture on a wall, a rail with a mounting section is first fixed to the wall. A furniture carcass is then suspended from the mounting section of the rail by means of at least two cabinet hangers, each with a hook, which are fixed to the carcass. Simultaneously with or after the suspension, a fastening element is arranged on an upper surface of the furniture carcass. This fastening element is connected to the rail or integrally formed with the rail. The fastening element is then fixed to the furniture carcass by means of at least one fastening device, for example, by screwing it in place. This securely fixes the furniture carcass to the rail, and the fastening element contributes to the overall stability by being fixed to the furniture carcass.This is particularly advantageous when, viewed lengthwise along the rail, there is a certain distance between the fasteners used to fix the rail to the wall and the mounting hooks, for example, more than 10 cm, which can cause the rail to deform, especially under heavy loads. This deformation is reduced when the fastener is fixed to the top of the furniture body, thus minimizing the lifting of the furniture body away from the wall.

[0014] In a preferred embodiment, after the furniture body has been hung, the furniture body is raised by means of an adjustment mechanism of the cabinet hanger, for example until the furniture body rests against an underside of a horizontal web of the rail or is arranged at approximately the same height as such a horizontal web.

[0015] The invention is explained in more detail below with reference to several exemplary embodiments and the accompanying drawings. These show:

[0016] Figures 1A and 1B show two views of a suspension system according to the invention for a piece of furniture;

[0017] Figure 2 shows a perspective view of a modified suspension system;

[0018] Figures 3A to 3C show several views of the rail of the suspension system of Figures 1 and 2;

[0019] Figure 4 shows a perspective view of a modified suspension system;

[0020] Figures 5A and 5B show two views of a further embodiment of a suspension system according to the invention;

[0021] Figure 6 shows a perspective view of the rail of the suspension system of Figure 5;

[0022] Figure 7 shows a perspective view of the fastening element of the suspension system of Figure 5, and

[0023] Figure 8 shows a perspective view of a modified rail for the suspension system of Figure 5. Figures 1A and 1B show a suspension system by means of which a piece of furniture with a cabinet body 1 can be fixed to a wall. The cabinet body 1 comprises a top panel 2, a base 4, and two side panels 3 that connect the top panel 2 to the base 4, with only one side panel 3 being shown. Adjacent to each side panel, a cabinet hanger 6 is fixed in the area of ​​a rear panel 5 of the cabinet body 1. The cabinet body 1 can be part of a wall cabinet for a kitchen or bathroom, which is suspended from the wall. The cabinet body 1 is preferably made of panels of a wood-based material.

[0024] The cabinet hanger 6 is connected to the side panel 3 by one or more screws 7, whereby corresponding pins engage in recesses in the side panel 3 and are penetrated by a screw 7. Alternatively, the cabinet hanger 6 can also be fixed by screwing it into the top panel 2, by a diagonally oriented screw between the back panel and the side panel, or by gluing in pins.

[0025] Each cabinet hanger 6 includes a mounting hook 8, which is adjustable relative to the part of the cabinet hanger 6 fixed to the furniture body 1, for example, by pivoting or sliding it. By adjusting the position of the mounting hook 8, the distance of the furniture body 1 from the wall and the height of the furniture body 1 can be changed.

[0026] The suspension system comprises a rail 10, made in particular of bent sheet metal or an extruded plastic or metal material, which can be fixed to a wall and has a lower hook-shaped retaining section 11. The mounting hooks 8 of the respective cabinet hangers 6 are attached to the hook-shaped retaining section 11 to fix one or more furniture bodies 1 to the rail 10. The rail 10 includes a vertical leg 12 that can be placed against a wall. Several mounting holes 16 are recessed in the vertical leg 12, which are at least partially penetrated by screws 15. The position of the screws 15 depends on the wall design, and in the case of a lightweight wall with posts at regular intervals, the position of the screw 15 can be spaced away from the cabinet hanger 6 along the longitudinal direction of the rail 10, which worsens the leverage under load.The rail 10 comprises, in addition to the vertical leg 12, an upper horizontal leg that projects from the wall and is arranged with a section on the top of the furniture body 1. This section of the horizontal leg forms a fastening element 13 in which one or more openings 14 for fasteners are provided. Fasteners, in particular screws, are inserted into at least one opening 14, preferably at least two openings 14, to firmly connect the fastening element 13 to the furniture body 1. The fasteners can be screwed either into the top panel 2 or into the upper end face of the side panel 3. The number of fasteners can be selected depending on the size of the furniture body 1.

[0027] In the furniture carcass 1 of Figures 1A or 1B, a recess 9 is milled into the upper area of ​​each side wall 3, allowing the rail 10 to be fixed continuously to the wall, for example over a length of more than 1 m, so that several furniture carcasses 1 can be hung side by side on the rail 10. The recess 9 allows the back of the side wall 3 to rest directly against a wall.

[0028] Figure 2 shows a modified embodiment of the furniture carcass 1 in which the side wall 3 no longer has a continuous recess, but only a pocket to accommodate an end section of the rail 10. This means that the rail 10 remains essentially invisible in one direction (longitudinal view) and is concealed behind the side wall 3, at least with respect to the vertical leg 12. Optionally, such a pocket can be omitted if the rail 10 terminates on the furniture carcass 1 in front of the side wall 3. Alternatively, the furniture carcass 1 can also be positioned at a distance from the wall using the cabinet hangers 6.

[0029] Figures 3A to 3C show the rail 10 for the suspension systems of Figures 1 and 2. The rail 10 is essentially angled and comprises the vertical leg 12 with the mounting openings 16 and the upper horizontal web, which forms an integral fastening element 13 in which openings 14 for fasteners, such as screws, are formed. The hook-shaped retaining section 11 is integrally formed on the vertical leg 12. The mounting openings 16 are designed as elongated slots, inclined longitudinally to the horizontal, for example at an angle α between 10° and 30°, so that the rail 10 can be adjusted vertically along the length L of the mounting openings 16. The mounting openings 16 can be arranged at regular intervals, for example between 30 mm and 100 mm.The mounting opening 16 can optionally be designed with a wave-like shape or projections on at least one long side of a wall. The rail 10 can then be fixed to the mounting opening 16 using a wall mounting device, for example a screw, and the rail 2 is better secured against slippage.

[0030] Figure 4 shows a modified rail 10' for a suspension system, which is otherwise designed as shown in Figure 1. The rail 10' includes mounting openings 16' on the vertical leg 12, which are designed as elongated holes, with the longitudinal direction of the mounting openings 16' extending essentially horizontally. This eliminates the possibility of adjusting the height of the rail 10' on the wall, whereas the height of the furniture body 1 can be adjusted via an adjustment mechanism on the cabinet hanger 6.

[0031] Figures 5A and 5B show another embodiment of a suspension system in which the furniture carcass 1 is suspended from a modified rail 20. The rail 20 includes a lower hook-shaped retaining section 21 into which a hook 8 of the cabinet hanger 6 is inserted. Mounting holes 28 for screws 15 are provided on a vertical leg 22 of the angled rail 20 to fix the rail 20 to a wall. Optionally, the mounting holes 28 can also be designed as angled elongated holes, as shown in Figure 3C.

[0032] The rail 20 comprises an upper horizontal web 23 in which several openings 24 are recessed. An end section 26 of a web-shaped fastening element 25 is inserted into at least one of the openings 24. The fastening element 25 is arranged on an upper surface of the furniture carcass 1, in particular on the top panel 2, and includes an opening 27 for a fastening element, for example a screw, to firmly connect the fastening element 25 to the furniture carcass 1, so that the furniture carcass 1 is also held to the rail 20 via the end section 26. The end section 26 is U-shaped and thus holds the furniture carcass to the rail 20 against movement away from the wall. Figure 6 shows the rail 20 in detail. The rail 20 is angled, with the horizontal web 23 being relatively short and having openings 24 at regular intervals for fixing a fastening element 25.Mounting openings 28 for wall mounting are also provided at regular intervals on the vertical leg 22, and the hook-shaped retaining section 21 is formed on one underside of the leg 22.

[0033] Figure 7 shows a fastening element 25 which is web-shaped and has a bent end section 26. The end section 26 is U-shaped and includes a fastening web 29 which, in the mounted position, projects towards the wall and secures the end section 26 against detachment from the upper web 23 of the rail 20.

[0034] Figure 8 shows a modified rail 20', which is designed like the rail of Figure 6 and has a vertical leg 22 with a hook-shaped retaining section 21. However, the upper horizontal web 23 is double-layered, so that the openings 24 extend through two layers of the upper horizontal web 23, which provides improved stability when fixing the fastening elements 25.

[0035] The rails 10, 10', 20, 20' are preferably made of bent sheet metal and can be fixed to a wall at the required length. The fastening element 25 is also preferably made of metal, but can also be made of plastic or a textile material.

[0036] The above embodiments can be combined in any way desired. For example, the side wall 3 can optionally have a milled recess 9, or only a milled pocket, or no recess in the area of ​​the extension of the rail 10, 10', 20 or 20'.
