Description

The invention relates to a piece of furniture with a furniture body that has two opposite body side walls and with at least one pair of guide units for guiding a movable furniture part, in particular a drawer, in the furniture body, wherein the body side walls each have at least one mounting interface that has at least two fastening holes arranged one behind the other in a side wall depth direction, to which the guide units of the pair are fastened opposite each other, wherein the body side walls each have at least two protrusions arranged one above the other in a side wall height direction to increase their rigidity, wherein the protrusions are raised on the inside of the respective body side wall and wherein at least one mounting interface is arranged in the side wall height direction between adjacent protrusions, wherein the at least one mounting interface is recessed in a groove-like manner relative to the protrusions and has a mounting surface having the fastening holes and wherein several mounting interfaces are provided, each of which is arranged between two protrusions arranged adjacently in the side wall height direction.

A piece of furniture of this type is, for example, from the FR2.204.959 A5 The furniture described there has a furniture body with two opposing side walls, on the inside of which a link structure is formed which extends inwards from the rest of the side wall and has several rail profiles lying one above the other in the vertical direction. A guide unit can be fastened between two rail profiles lying adjacent to each other in the vertical direction using fastening holes.

The JP 2002 017486 A1 or the FR2204959 A5 discloses a guide structure for a drawer, with two opposing side walls made of metal material or plastic, which has a plurality of fastening interfaces for fastening a body rail of a guide unit.

Every household has several pieces of furniture with furniture bodies in which drawers are movably guided. The drawers are guided by guide units, one of which is attached to the left side wall of the furniture body and another to the right side wall opposite. The furniture bodies can be made of wood or metal. Since drawers are quite heavy, especially when loaded, the attachment of the associated guide units to the side walls must also be designed in such a way that the weight of the drawer is reliably supported. This requires the side walls of the furniture body to be sufficiently stable, so thin plywood panels, for example, are not suitable for such side walls.

The side walls of furniture bodies known from the state of the art are therefore relatively thick and bulky, which means that a relatively large amount of installation space is required. This is not particularly aesthetically pleasing either.

The object of the invention is therefore to create a piece of furniture of the type mentioned at the outset which, compared to furniture from the prior art, requires less installation space overall and is aesthetically pleasing, particularly with regard to the design of the side walls.

This object is achieved by a piece of furniture having the features of independent claim 1.

The furniture according to the invention according to claim 1 is characterized in that the groove-like recessed mounting interfaces are each connected to one another at their front and rear sides located in the side wall depth direction via a vertical groove, such that a ladder-like structure is formed.

The features increase the rigidity of the side walls, so that their wall thickness can be significantly lower than in the state of the art, while still allowing the guide units to be reliably attached to the side wall. A finished body with side walls designed in this way is lighter than conventional finished bodies. In addition, the side walls with lower wall thickness have a significant influence on the aesthetics. Another aspect that should not be neglected is that the mounting interfaces for connecting the guide units are arranged in the side wall height direction between adjacent features. The clear width of the furniture body, which is available for mounting the guide units, is therefore not affected by the features. On the contrary, compared to conventional furniture bodies with relatively wide side walls, this solution allows a movable furniture part, in particular a drawer, to be used with a larger width and thus, in the case of a drawer, more storage space.

In a further development of the invention, the fastening holes of the mounting interfaces are designed for tool-free mounting of the guide units on the body side walls. It is possible, for example, for the fastening holes to be designed like a keyhole as part of a bayonet connection. An alternative tool-free fastening can be achieved by means of a clip connection, whereby, for example, clip elements arranged on the guide units could be clipped into the fastening holes.

As an alternative to the tool-free fastening of the guide units to the fastening holes of the mounting interfaces, non-tool-free assembly is also possible, for example by means of a screw connection.

In a further development of the invention, the guide unit has a body rail and at least one guide rail that is guided in a linearly movable manner on the body rail, wherein the body rail is fastened to the associated mounting interface on the body side wall. The body rail can have several fastening angles arranged one behind the other in the longitudinal direction of the rail or a single continuous long fastening angle for fastening it in the area of the associated Mounting interface on the cabinet side wall. It is possible that several guide rails are provided, of which one guide rail is a pull-out rail and another rail is a middle rail. The middle rail is inserted between the cabinet rail and the pull-out rail and is guided in a linear manner both in relation to the pull-out rail and in relation to the cabinet rail. The combination of cabinet rail, middle rail and pull-out rail is also referred to as full extension.

The at least one mounting interface is recessed in a groove-like manner relative to the features and has a mounting surface having the fastening holes.

Several mounting interfaces are provided, each of which is arranged between two adjacent features in the side wall height direction. It is therefore possible for the furniture body to have several movable furniture parts lying one above the other, for example drawers, which are each attached to the associated body side walls via mounting interfaces and associated fastening holes, wherein the mounting interfaces are each arranged between features on the body side wall.

The groove-like recessed mounting interfaces are each connected to one another at their front and rear sides in the side wall depth direction via a vertical groove in such a way that a ladder-like structure is formed.

In a further development of the invention, the fastening holes of a respective mounting interface are divided into several hole groups which each have a number of fastening holes arranged in a common height plane in the side wall depth direction, with the hole groups being arranged one above the other in the side wall height direction. The arrangement of the fastening holes in hole groups offers the advantage that the guide unit to be fastened can be adjusted in the height direction and depth direction and that pairs of aligned fastening holes and assembly holes can always be found on the side of the guide unit, even in different adjustment positions.

In a further development of the invention, the body side walls are designed as sheet metal components, in particular sheet metal components. It is possible, for example, to design the body side walls as thin sheet metal components.

In the case of sheet metal body side walls, the material thickness of such side walls is less than 3 mm, preferably 0.5 to 1.5 mm, in particular 0.7 mm to 1 mm.

In the case of side walls that are not made of sheet metal, the body side walls can have a wall thickness in the range of 4 mm to 30 mm, preferably 6 mm to 19 mm, in particular 8 mm to 16 mm.

In the case of body side walls made of sheet metal, there is the advantage that they are much easier to clean than wooden components and cleaning can be carried out using chemicals. Such furniture is not only used in the kitchen, but can also be used in office furniture designed in this way.

In a further development of the invention, the furniture has at least one movable furniture part, in particular a drawer, which is guided in the furniture body by means of a pair of guide units. However, other movable furniture parts are also conceivable, for example a furniture pull-out not designed as a drawer or a furniture flap.

In a further development of the invention, at least one of the body side walls has holding means for holding an electrical line. At least one electrical line, for example a power cable, is expediently held on the holding means. Alternatively or additionally, it is possible for the body side walls to have at least one opening for the passage of an electrical line. At least one electrical line is expediently led through the associated opening.

In a further development of the invention, the furniture has a base and a rear wall, which are each connected to the body side walls by means of fastening means, wherein the fastening means are preferably designed for tool-free fastening of the body side walls, base and rear wall to one another.

In a particularly preferred manner, the fastening means have claw elements formed in particular on the body side walls, which claw into the material, in particular wood material, of the floor and/or the rear wall. A furniture body produced in this way is expediently a hybrid component, with body side walls made of metal and the floor and rear wall made of wood.

In a further development of the invention, at least one of the body side walls has at least one cavity in which electrical functional components, in particular electrical cables and/or at least one lighting element for illuminating the movable furniture part are accommodated.

In a further development of the invention, the body side walls have a coating for sound reduction, particularly on their outside.

It is possible for the body side walls to be screwed to the top with wooden cross profiles, preferably clipped with a steel angle to ensure a suitable body width.

It is possible that height-adjustable feet are integrated into the carcass side walls.

It is also possible for the body side walls to each have locking and quick-connection elements for connecting other furniture bodies. The locking and quick-connection elements can, for example, be integrated into the associated body side walls, preferably as a metal and/or plastic part that can be clipped on or as a metal and/or plastic part that can be screwed onto the associated body side wall.

The Figures 1 to 8 show a preferred embodiment of a piece of furniture 11 according to the invention. The piece of furniture can be used as kitchen furniture in the kitchen area or as office furniture in an office. The piece of furniture 11 according to the invention comprises, in an exemplary manner, A movable furniture part 12 ( Figure 3 ), which is shown here as an example in the form of a drawer. However, it is also possible to use other movable furniture parts 12 as drawers, for example differently designed furniture pull-outs. In the following, however, the invention can be explained using the example of a drawer.

The furniture 11 has a furniture body 13, which in the example shown has two opposite body side walls 14a, 14b. The furniture body 13 also has a base 15, which is connected to the two body side walls 14a, 14b in a manner explained in more detail below and keeps the two body side walls 14a, 14b at a distance from each other. On the upper side of the furniture body 13 opposite the base 15, an upper closure is provided, which is shown by way of example in the form of two cross profiles 16a, 16b, which are each connected on the one hand to one and on the other hand to the other body side wall 14a, 14b. Of course, it is also possible to use differently designed upper closures of the furniture body 13 instead of the cross profiles 16a, 16b, for example an upper cover that completely closes off the upper side of the furniture body 13. However, it is often the case, especially with kitchen furniture, that such furniture is arranged underneath a large cover or worktop, which in turn forms the upper end of several such pieces of furniture together.

In the example of office furniture, however, an upper cover plate is certainly conceivable, for example in the case that the furniture is a roll container, which then has such an upper cover plate as a uniformly handled piece of furniture.

Furthermore, the furniture body 13 can have a rear wall (not shown) which forms the rear end of the furniture 12.

Overall, in the example shown, the two body side walls 14a, 14b, the base 15 and the two cross profiles 16a, 16b define an interior space 17 in which several drawers are accommodated in a manner explained in more detail below and are each movably guided by means of guide units 18. In the example shown, it is possible, for example, for five drawers lying one above the other in a side wall height direction 19 to be accommodated in the interior space 17 of the furniture 11.

An essential aspect of the invention is the connection of the guide units 18 to the associated body side walls 14a, 14b.

A pair of guide units 18 is provided for guiding a drawer, wherein the body side walls 14a, 14b each have at least one mounting interface 20a, 20b, which have at least two fastening holes 22 arranged one behind the other in a side wall depth direction 21, to which the guide units 18 of the pair are fastened opposite one another.

Compared to conventional furniture, the furniture 11 according to the invention has body side walls 14a, 14b with a relatively thin wall thickness. On the one hand, this results in a weight reduction compared to conventional furniture and, on the other hand, such furniture with relatively thin-walled body side walls 14a, 14b also meets increased design requirements, which are often encountered today.

However, the reduction of the wall thickness of the body side walls 14a, 14b to achieve the above-mentioned results does not lead to the effect that the side walls would become unstable and a reliable fastening of the guide units at the mounting interfaces on the body side walls 14a, 14b is not possible.

In the furniture according to the invention, the body side walls 14a, 14b each have at least two protrusions 23 arranged one above the other in the side wall height direction 19 to increase their rigidity, wherein the protrusions 23 are raised on the inner side 24 of the respective body side wall 14a, 14b and are arranged between adjacent protrusions 23 in the side wall height direction 19 at at least one mounting interface 20a, 20b.

Because the mounting interfaces 20a, 20b are arranged between two adjacent protrusions 23 in the side wall height direction 19, the inwardly raised protrusions 23 do not impair the installation space available for guiding the drawer.

In the example shown, the body side walls 14a, 14b are designed as sheet metal components, in particular sheet metal components. It is possible, for example, to form the features 23 from a flat, level-arranged raw sheet metal part by means of an embossing or punching process. All features can expediently be formed using an embossing or punching process.

Particularly preferably, sheet metal components made of thin sheet metal, in particular thin steel sheet metal, are provided as body side walls 14a, 14b. The wall thickness of such thin sheet metal body side walls is less than 3 mm, preferably 0.5 mm to 1.5 mm, in particular 0.7 mm to 1 mm.

As in particular in Figure 1 shown, the mounting interfaces 20a, 20b according to the invention are groove-like compared to the features 23 recessed and have a mounting surface 25 having the fastening holes 22. The groove-like recessed mounting interfaces 20a, 20b are each connected to one another at their front side 26 and rear side 27 lying in the side wall depth direction via a vertical groove 28 in such a way that a ladder-like structure is formed.

In the example shown, the mounting interfaces 20a, 20b are extended on their front side 26 beyond the vertical channel by a channel section 29 which is relatively short in the side wall depth direction and which ends at the front edge of the body side walls 14a, 14b.

As already mentioned, the guide units 18 for guiding the drawer are attached to the mounting interfaces 20a, 20b. As shown in particular in the example in Figure 3 As shown, the furniture is equipped with three drawers lying one above the other in the side wall height direction 19, with three pairs of guide units being provided, one pair of which is used to guide a drawer. The guide units 18 of a pair are attached to opposite mounting interfaces 20a, 20b of one and the other body side wall 14a, 14b. The associated mounting interfaces 20a, 20b are therefore located at the same height as the associated body side walls 14a, 14b. In the following, only the attachment of one guide unit 18 of a guide unit pair is described, with the attachment of the opposite other guide unit taking place in the same way to the associated body side wall 14a, 14b.

The guide units 18 may be so-called standard guide units, i.e. a modification the guide units 18 for the purpose of fastening to the associated mounting interface 20a, 20b is not necessary.

A respective guide unit 18 has a body rail 30 and at least one guide rail 31 which is guided linearly movably on the body rail 30, wherein the body rail is fastened to the associated mounting interface 20a, 20b on the body side wall 14a, 14b.

In the example shown, two guide rails 31 are provided, of which only one is shown, one of the guide rails 31 being a drawer rail, which in turn is connected to the drawer via corresponding coupling means, and a middle rail (not shown) arranged between the drawer rail and the body rail 30 and movably guided relative to these two rails. Such an arrangement is also called full extension.

The body rail 30 is used to fasten the guide units to the associated mounting interface 20a, 20b of the associated body side wall 14a, 14b, which, when fastened, is fixedly connected to the associated body side wall 14a, 14b.

The body rail 30 has a body angle 32 which has a guide section 33 ( Figure 5 ) which, when the body rail 30 is mounted, projects inwards from the inner side 24 of the associated body side wall 14a, 14b. The middle rail is guided on the guide section 33 via corresponding guide means and the drawer rail is guided on this in turn via corresponding guide means in a linearly movable manner. The body angle 32 also comprises a mounting section 34, which for example in Figure 3 and in the Figure 4 as well as in the Figure 5 is shown in more detail. The mounting section 34 is designed like a plate and rests with its outer surface on the mounting surface 25 of the mounting interface 20a, 20b. The mounting section 34 has a plurality of mounting holes 36 so that suitable ones of the mounting holes 36 can be aligned with the fastening holes 22 of the mounting interface 20a, 20b in order to carry out the subsequent assembly process.

As in particular in Figure 3 shown, the fastening holes 22 of the mounting interface 20a, 20b are arranged in a plurality of hole groups 35a, 35b, each of which has a plurality of fastening holes 22 arranged in a common height plane in the side wall depth direction 21, wherein the hole groups 35a, 35b are arranged one above the other in the side wall height direction 19. In the example shown, two hole groups 35a, 35b are provided which are arranged one above the other in the side wall height direction 19, of which a first hole group 35a has a plurality of, for example 6, fastening holes which are arranged one behind the other in the side wall depth direction. The second hole group 35b, which is offset in the side wall height direction 19 and is lower in the example, also consists of a plurality of fastening holes arranged one behind the other in the side wall depth direction 21, for example three in number. The large number of fastening holes 22 in the hole groups 35a, 35b, in conjunction with the mounting holes 36 on the mounting section 34 of the body angle 32, allows the body rail 30 to be adjusted both in the side wall height direction 19 and in the side wall depth direction 21 and, depending on the adjustment position, the mounting holes 36 and fastening holes can still be aligned to match.

As in particular in Figure 3 As shown, the groove-like recess of the mounting interfaces 20a, 20b also forms a type of assembly aid when assembling the body angle 32 in such a way that the dimension of the groove-like recess in the side wall height direction 19 corresponds approximately to the height of the mounting section 34 and therefore it is clearly visible during assembly that the mounting section 34 of the body angle 32 belongs in the groove-like recess.

As particularly in the Figures 4, 5 and 8th As shown, the body angle 32 according to the first embodiment is screwed to the inner side 24 of the associated body side wall 14a, 14b via screw fastening means after aligning the position of the mounting section 34 on the mounting surface 25 of the mounting interface 20a, 20b and the associated alignment of the matching fastening holes 22 on the one hand and mounting holes 36 on the other hand.

As in particular in Figure 8 As shown, the screw fastening means comprise a fastening screw 37, in particular in the form of a self-tapping fastening screw. The screw fastening means also include a fastening sleeve 38, which is expediently made of plastic.

As further stated in Figure 8 As shown, the associated fastening hole 22 in the body side wall 14a, 14b is arranged in a depression 39 which is formed by pressing out the material of the body side wall 14a, 14b from the inner side 24 to the outside.

The fastening sleeve 38 has a disk-shaped sleeve head 40, to which a cylindrical base section 42 is connected along a sleeve longitudinal axis 41, which passes through the fastening hole 22. At the free end of the fastening sleeve 38 there is a fixing section 43, the diameter of which is larger than the diameter of the cylindrical base section and also larger than the diameter of the fastening hole. The fixing section 43 consists of two semicircular segments 44, which are separated from one another by a radially running longitudinal slot 45. The two segments 44 are deformable in such a way that the fastening sleeve 38 with the fixing section 43 and the segments 44 in front can be pushed through the fastening hole 22 while deforming the segments 44, wherein the segments 44 snap back into their original position after passing through the fastening hole and ensure that the fastening sleeve 38 can no longer come out of the fastening hole 22 against the direction of insertion, since the segments 44 are supported on the outside of the body side wall 14a, 14b. When the fastening sleeve 38 is pressed in, the sleeve head 40 is positioned in the recess 39, whereby the sleeve head 40 does not protrude beyond the inside of the body side wall 14a, 14b, i.e. beyond the mounting surface 25.

To fasten the body angle, the associated fastening screw 37 is then screwed through the central opening 46 in the fastening sleeve 38, wherein the diameter of the central opening 46 in the area of the sleeve head 40 is significantly smaller than the diameter of the screw shaft 47, so that the fastening screw 37 cuts into the material of the sleeve head 40 with its thread and therefore clamps the mounting section 34 to the mounting surface 25.

As in particular in Figure 3 As shown, the body side walls 14a, 14b each have at least one opening 48 for the passage of an electrical line, in particular in the form of a power cable. In the example shown, the openings 48, for example two in number, are arranged in the side wall depth direction 21 as seen from the front side 26 of the mounting interfaces 20a, 20b behind the ladder-like structure of the mounting interfaces 20a, 20b. The openings 48 can, for example, have a slot-like shape.

As in particular in Figure 4 and also in Figure 5 shown, at least one recess 49 is formed on the body side walls 14a, 14b, which is expediently formed in the area of the embossings 23. The recesses 49 can be made, for example, by an embossing or punching process, which can be carried out after the embossings 23 have been formed. The recesses 49 serve to accommodate a lighting element 50, which is shown, for example, in the form of an LED element. As shown in particular in Figure 7 As shown, the LED element is located in a receiving sleeve 51, which in turn is inserted into a mounting hole 52 provided in the recess 49 and is mounted there. The longitudinal axis 53 of the receiving sleeve 51 is expediently directed from the outside to the inside at an angle to the base 15, so that the light cone generated by the LED element is directed diagonally downwards and is particularly suitable for illuminating the interior of the drawer.

As in Figure 6 As shown, it is possible that unused fastening holes 22 of the mounting interfaces 20a, 20b are pre-occupied by fastening sleeves 38.

As in particular in Figure 2 As shown, the body side walls 14a, 14b and the base 15 are connected by means of fastening means 54. The fastening means 54 are tool-free fastening of the body side walls to the floor.

In the example shown, the body side walls 14a, 14b are made of sheet metal as mentioned and the base 15 is made of wood. For this combination, fastening means 54 are suitable which have claw elements 55 which claw into the material of the base 15.

We also in Figure 2 As shown, fastening webs 56 are formed on the lower edges of the body side walls 14a, 14b, which can be produced, for example, by a substantially right-angled bend of the lower edge of the body side walls 14a, 14b. The claw elements 55 are located on the upper side of the fastening webs 56, i.e. directed towards the interior 17, so that the base 15 can be inserted and the claw elements can be driven into the underside of the base 15.

As already mentioned, cross profiles 16a, 16b are provided as the upper end of the furniture body 13 according to the first embodiment, which can consist of wood material, for example, and are fastened to the body side walls 14a, 14b by means of fastening profiles 57.

As in particular in Figure 1 shown, the fastening profiles 57 can be designed in such a way that a connection to an adjacent furniture body 13 of any kind is possible via a coupling interface 58 provided for this purpose. In the example case, the coupling interface has several, in particular two, fastening holes 59 ( Figure 3 ) on.

The Figures 9 and 10 show an embodiment of the furniture not belonging to the invention. In contrast to the previously described preferred embodiment, the body side walls 14a, 14b of the second embodiment are designed differently. The body side walls 14a, 14b are expediently also made of sheet metal, in particular sheet metal. The body side walls 14a, 14b of the second embodiment also each have at least one mounting interface 60. The mounting interface 60 in turn has several, for example two, fastening holes 61, which are arranged one behind the other in the side wall depth direction 21. In contrast to the previously described first embodiment, the fastening holes 61 of the second embodiment are significantly larger and in the form of window-like openings. The mounting interface 60 is again designed to be recessed in the manner of a channel, wherein in the example shown the two fastening holes 61 are preferably arranged in the form of window-like openings at the front and rear ends of the channel-like recess 62.

As in the first embodiment, guide units 18 are attached to the mounting interfaces of the second embodiment. Here, too, two guide units 18 of a pair are attached opposite one another and serve together to guide a drawer.

In contrast to the first embodiment described above, a respective guide unit 18 is designed differently. The body rails 63 of such a guide unit 18 have two mounting elements 64a, 64b arranged one behind the other in the longitudinal direction of the rails. The mounting elements correspond to the window-like mounting holes 61 on the mounting interface 60.

The mounting elements 64a, 64b replace the mounting section 34 of the standard body rail. The mounting elements 64a, 64b each have a base section 67a, 67b attached to the guide section 66 of the body rail 63, in particular in one piece, and a plate-shaped mounting section 68a, 68b aligned in the height direction of the guide unit 18, connected to the base section 67a, 67b and protruding transversely from it. The outline of the mounting sections 68a, 68b is each smaller than the opening cross-section of the associated fastening hole 61, such that the mounting section 68a, 68b can be pushed through the fastening hole 61 and is fastened by means of holding means to the edge 69 formed by the body side wall 14a, 14b and surrounding the fastening hole 61. The holding means have a clamping tongue 70 which is preferably bent out of the material of the mounting section 68a, 68b against the insertion direction and by means of which the mounting section 68a, 68b is clamped to the edge 69 of the fastening hole 61.

In this case, the guide unit 18 is connected to the body side wall 14a, 14b without tools by engaging and clamping the clamping tongue 70 with the edge 69 of the associated fastening hole 61.
