Description

Technical field

[0001] The invention relates to a multi-part system which is provided for attaching a cover to an upholstered body of, in particular, a piece of furniture, and to a corresponding piece of furniture.

[0002] Such cover attachment systems are generally used to connect covers of seat surfaces, backrests and / or armrests of, for example, armchairs, sofas, chairs or vehicle seats to the upholstery, which is regularly designed as a foam part. State of the art

[0003] Typically, for the aforementioned purpose, fastening elements are foamed into the foam padding, to which corresponding retaining elements of the padding cover engage.

[0004] Thus, a fastening element known from DE 195 30 279 C2 has an insert held in the upholstery, which is clamped around by two bracket parts that have an assembly and disassembly access facing the top of the upholstery for retaining elements of the upholstery cover. With this solution, the cover is replaceable, but the stability of the anchoring in the upholstery could be improved.

[0005] Furthermore, WO 2016 / 170687 A1 discloses a clip socket which can be engaged with at least one cover which covers at least part of an outer surface of a foam molded body and which is embedded in a cover fastening groove of the foam molded body.

[0006] The clip socket comprises a bottom wall, a pair of right and left side walls extending to the right and left and upwards from the bottom wall, and a pair of right and left engaging sections extending from the upper sides of the right and left side walls towards a center point between the right and left side walls. The right and left engaging sections can be brought into engagement with the clip insert. The clip socket includes, between the right and left side walls, a clip insert receiving chamber that can receive the clip insert between the right and left engaging sections, as well as insertion spaces for foam material on the right and left sides of the clip insert receiving chamber for inserting material of the foam insert.While this solution provides a sufficiently firm anchoring in the foam molded body, it is disadvantageous with regard to the possible replaceability of the cover.

[0007] The present invention is therefore based on the objective of providing a system for attaching a cover to an upholstered body of, in particular, a piece of furniture, which on the one hand allows easy replacement of the cover and at the same time ensures a reliable and robust anchoring in the upholstered body. Description of the invention

[0008] The problem is solved according to the invention by a system as defined in claim 1 and by a piece of furniture as defined in claim 15.

[0009] In a first aspect, the invention comprises a system for attaching a cover to an upholstered body, in particular a piece of furniture. The system comprises a longitudinal profile configured to be fixed in the upholstered body and a longitudinal clip configured for attaching the cover. The longitudinal profile defines a slot-shaped receptacle for the longitudinal clip, wherein the slot-shaped receptacle has a first coupling section, and the longitudinal clip has a second coupling section. The first coupling section of the slot-shaped receptacle of the longitudinal profile and the second coupling section of the longitudinal clip are configured to form a positive and / or force-fit connection with each other.

[0010] In the present case, the term “piece of furniture” refers in particular to a sofa, an armchair, a chair or a vehicle seat or a vehicle rear bench, as well as any seats, benches or armchairs of buses, trams, trains or airplanes.

[0011] In this context, the term “upholstery body” generally refers to the basic frame or structure of the corresponding piece of furniture together with the applied foam or other upholstery material. In this respect, the term “upholstery body” also includes a body made of a material other than foam.

[0012] In this context, the term “longitudinal profile” refers to a profile that regularly has a greater longitudinal dimension than a transverse dimension. The profile preferably has at least one central, upwardly open, slot-shaped recess formed by two U-shaped legs projecting from a base plate. The U-shaped legs may each have coupling sections directed inwards, i.e., into the slot-shaped recess, at their upper and distal end regions. Furthermore, the profile regularly has extensions projecting laterally from the base plate with through-openings, which serve to anchor the longitudinal profile in the foam material. The extensions preferably have an L-shape. The longitudinal profile is preferably formed as an extrusion profile from a predominantly rigid plastic material. “Predominantly rigid” in this context means that a certain degree of flexibility is still present.Flexibility is maintained.

[0013] The term “longitudinal clip” refers to a clip shape which regularly has a greater longitudinal dimension than a transverse dimension. The longitudinal clip can be inserted into the slot-shaped receptacle of the longitudinal profile and has coupling sections which correspond to or are opposite to the coupling sections of the U-shaped legs of the longitudinal profile. In this respect, the longitudinal clip is in particular designed as a double-sided hook, i.e., it has two clip legs which have coupling sections directed outwards (i.e., towards the inside of the slot-shaped receptacle of the U-shaped profile) which form a detachable connection with the coupling sections of the U-shaped legs. The longitudinal clip is preferably made of a plastic material that is at least partially flexible.

[0014] Preferably, the first coupling section of the U-shaped profile and the second coupling section of the longitudinal clip are designed in a mirror-image manner, i.e., they have interlocking forms, such as locking lugs or locking projections and corresponding indentations or recesses.

[0015] Preferably, the first coupling section or the second coupling section is designed as a projection, wherein the second coupling section or the first coupling section is then designed as a recess corresponding to the projection. In this way, a particularly effective and easily detachable connection can be achieved between the longitudinal profile and the longitudinal clip.

[0016] Preferably, the U-shaped profile has a base plate from which a first U-leg and a second U-leg project substantially perpendicularly, with the slot-shaped recess for the longitudinal profile being formed between the first U-leg and the second U-leg. This ensures easy insertion of the longitudinal clip.

[0017] Preferably, the first U-shaped leg and the second U-shaped leg are each hook-shaped and each have a recess as a coupling section in their distal end region, with the two recesses facing each other. This allows, in particular, the longitudinal clip to be locked in place near the outside of the piece of furniture or the upholstered part, which facilitates easier replacement.

[0018] Preferably, the base plate has a first, preferably L-shaped, extension and a second, preferably L-shaped, extension, each of which projects substantially horizontally from the base plate (i.e., they lie in a plane with the base plate). The shorter leg of the “L” preferably projects substantially vertically upwards, i.e., in the same direction as the two U-shaped legs. In this way, particularly good positioning and fixation in the foam or upholstery material can be achieved.

[0019] Preferably, the first preferably L-shaped extension and the second preferably L-shaped extension each have several through-openings. These through-openings allow for a particularly secure anchoring of the U-shaped profile in the foam or cushioning material. The through-openings are preferably designed as round or oval holes or elongated holes through which the foam or cushioning material penetrates, creating a robust, form-fit connection. Other geometries for the through-openings, such as rectangular, square, triangular, or polygonal shapes, are also conceivable.

[0020] Preferably, the first preferably L-shaped extension and the second preferably L-shaped extension each have several indentations. Particularly when used in the lower area of, for example, a sofa, i.e., along the outer contour of the seat, a corresponding (lower) profile strip of the longitudinal profile must have a particularly pronounced flexibility for the corresponding curves in order to ensure precise assembly.

[0021] Preferably, the longitudinal clip has a base plate from which a first clip leg and a second clip leg project substantially perpendicularly (or at right angles). Furthermore, preferably, the first clip leg and the second clip leg each have a first projection (preferably in their distal end region) which corresponds to a recess in the first U-shaped leg and the second U-shaped leg. The projections are arranged facing away from each other. In this way, a structure that mirrors the coupling section of the U-shaped profile can be efficiently created, with the two clip legs of the longitudinal clip being designed to be flexible in order to reliably engage in the recesses when the longitudinal clip is inserted and to be easily removed from them.

[0022] Preferably, the longitudinal clip has an arrow-shaped retaining element arranged between the first clip leg and the second clip leg, which projects substantially perpendicularly from the base plate. More preferably, the arrow-shaped retaining element also has an arrowhead with undercuts configured for attaching, typically hook-shaped, mounting elements of a cover. This allows for a simple and reliable hook-in mounting of the cover's mounting elements, with the undercuts providing support and the pointed front of the arrowhead serving as an insertion aid.

[0023] Preferably, the first clip leg and the second clip leg each have a second projection at their distal end, which, in the assembled state, extends beyond the distal end of the first hook-shaped U-leg and the second hook-shaped U-leg, respectively, and which further preferably each forms a chamfer directed towards the arrowhead of the arrow-shaped retaining element. The second projections each form an outer termination of the system and also function as an insertion aid, which interacts with the arrowhead. The second projections form a clean transition to the foam and generate a smooth surface without foam build-up due to the reference stresses. It should be noted that the clip does not need to be replaced when changing the cover, but remains in the profile. Only the cover together with the sewn-on hooks may need to be removed.However, if the clip becomes damaged or defective, it can be removed and replaced. The second protrusions can then be used as a gripping tool to squeeze the two flexible clip arms together.

[0024] Preferably, the system comprises mounting elements of the cover which are configured to be mounted on the longitudinal clip. The mounting elements of the cover are preferably designed in the form of hooks which are clicked into the longitudinal clip, preferably engaging undercuts of the arrowhead. The cover is attached or sewn to the rear ends of the mounting hooks.

[0025] Another aspect of the present invention comprises a piece of furniture with an upholstered body and a system as described above, as well as with a cover which is attached to the longitudinal clip by means of the corresponding (hook-shaped) mounting elements.

[0026] The present invention thus enables the creation of a particularly efficient multi-part system in which the longitudinal profile is anchored particularly firmly in the foam or upholstery body and in which the longitudinal clip can be inserted into the longitudinal profile particularly easily and removed from it again in the event of a defect. The hooks, which are sewn onto the cover, are then inserted into the mounted clip. When the cover is replaced, the clip regularly remains in the longitudinal profile. Since the longitudinal profile is regularly made of a robust or at least predominantly rigid plastic material, it does not warp when the foam is applied or when the cover is mounted, which could later lead to the longitudinal clip becoming unintentionally easy to detach.

[0027] By first firmly embedding the longitudinal profile in the foam or upholstery body, then clicking the longitudinal clip into the U-shaped profile, and finally hooking the mounting elements of the cover into the longitudinal clip, an optimal combination of secure hold (i.e., of the U-shaped profile and the longitudinal clip) on the one hand and easy replaceability (of the cover along with its mounting elements) on the other hand can be provided.

In this context, the following provision applies to the entire subsequent description: If reference symbols are included in a figure for the purpose of graphical clarity, but are not mentioned in the immediately associated descriptive text, reference is made to their explanation in preceding figure descriptions.Furthermore, if the descriptive text directly pertaining to a figure mentions reference symbols that are not included in the figure itself, reference is made to the preceding and following figures. Similar reference symbols in two or more figures represent similar or identical elements.

[0031] Fig. 1 shows a perspective view of a basic body 25 for a sofa (i.e., without foam material) with a seat 23 and a backrest 22, as well as with the corresponding bracing. In the upper area of ​​the backrest 22, an upper profile strip Po with a longitudinal profile 1 is arranged, with only the underside and the openings 11 visible here. The corresponding longitudinal clip 5 and the upper cover are otherwise mounted (after the foam or upholstery material has been applied) from behind the backrest 22. In the front area of ​​the seat 23, a lower profile strip Pu with a U-shaped profile 1 is arranged, which, in addition to the openings 11, also has notches 12 to allow the profile strip Pu to adapt optimally to the curves. The design and arrangement of the notches 12 are illustrated in more detail in Figs. 5(B) and 6(B).The assembly of the corresponding longitudinal clip 5 and the lower cover is carried out (after application of the foam or padding material) from below the seat plate 23.

[0032] Figure 2 now shows the base body according to Figure 1, provided with the corresponding foam or upholstery material 21, which is referred to here as the foam or upholstery body 20. In the upper area of ​​the backrest 22, the upper profile strip Po is indicated and, essentially parallel to it, in the rear area of ​​the seat plate 23, the lower profile strip Pu.

[0033] Figure 3 schematically shows a side sectional view of a system according to the invention for attaching a cover to an upholstered body 20 of a piece of furniture, which in this case is mounted in the upper area of ​​a backrest 22 of the upholstered body 20. The longitudinal profile 1 is firmly anchored in or surrounded by the foam material 21, with the foam material 21 also penetrating the openings 11. The L-shaped extensions 4a and 4b, which project from or form an extension of the base plate 4, point outwards, i.e., towards the cover 30, which ensures a particularly robust anchoring of the U-shaped profile in the foam material 21.The longitudinal clip 5 is inserted into the slot-shaped receptacle 2 of the longitudinal profile 1 and engages with the first projection 6a of the first clip leg 5a in the indentation 3a of the first U-shaped leg 1a and with the first projection 6b of the second clip leg 5b in the indentation 3b of the second U-shaped leg 1b. The indentations 3a and 3b, together with the first projections 6a and 6b, each form the coupling sections in the area of ​​the slot-shaped receptacle 2. A second projection 6c is provided at the distal end of the first clip leg 5a and a second projection 6d at the distal end of the second clip leg. The distal end of the first U-leg 1a engages in the space between the projections 6a and 6c of the first clip leg 5a and preferably rests on the outwardly facing side of the projection 6a.Accordingly, the distal end of the second U-shaped leg 1b engages in the space between the projections 6b and 6d of the second clip leg 5b and preferably rests on the outwardly facing side of the projection 6b. The two second projections 6c and 6d each form a chamfer S, which is directed towards the arrowhead 8a of the arrow-shaped retaining element 8 and whose inner edge serves to support the hooks 9. The arrow-shaped retaining element 8 projects from the base plate 7 of the longitudinal clip at regular intervals from the first clip leg 5a and the second clip leg 5b, with the tip of the arrowhead 8a preferably extending beyond the lower end of the chamfer S. In this way, a particularly efficient insertion aid for the mounting elements 9 of the cover 30 is provided. Preferably, the mounting elements 9 of the reference 30 are designed in a hook shape, so that after insertion (i.e.Along the chamfer S and the arrowhead 8a), the undercuts 8b and 8c on the back of the arrowhead 8a engage or hook into place; simultaneously, the legs of the hook-shaped mounting elements 9 are supported at the lower end of the chamfer S by the first clip leg 5a and the second clip leg 5b, respectively. This ensures a particularly secure hook-in mounting. The cover 30 is usually sewn to the rounded (outwardly facing) ends of the mounting elements 9. To replace the cover 30, the operator simply needs to remove the hooks 9 from the longitudinal clip 5 (a tool such as a screwdriver may be used for this purpose). If both the rear and front covers are being replaced, the longitudinal clip may also need to be replaced; however, this is generally only necessary if it is damaged.

[0034] Fig. 4 illustrates a longitudinal profile 1 in a frontal view. The two L-shaped extensions 4a and 4b project horizontally from the base plate 4, with the shorter legs each projecting vertically upwards. The two U-shaped legs 1a and 1b each project vertically upwards from the base plate 4, with the essentially hook-shaped coupling sections 3a and 3b or the indentations facing each other. The base 2a of the slot-shaped receptacle 2 is preferably somewhat thicker than the longer legs of the L-shaped extensions 4a and 4b and has approximately the same length. The chamfer S' in the distal end region of the first and second U-shaped legs 1a and 1b, respectively, serves as an insertion aid for a longitudinal clip 5, and in particular for its underside, which has corresponding chamfers S".

[0035] Figure 5 shows a top view of an upper profile strip Po of a longitudinal profile (A) and a lower profile strip Pu of a longitudinal profile (B). In the lower profile strip Pu, the notches 12 between the individual through-openings 11 are visible in (B). These notches provide improved flexibility, for example, for the curves in the front area of ​​a seat plate 23 (see Figure 1). The notches 12 above and below the slot-shaped receptacle 2 are preferably arranged alternately with each other, i.e., offset from each other in the longitudinal direction. A notch 12 is preferably opposite a through-opening 11, and vice versa. The through-openings 11 are elongated.In the upper profile strip PO, as illustrated in (A), the through-openings 11 above and below the slot-shaped receptacle 2 are preferably arranged opposite each other and have a less elongated, hole-like design than the through-openings of the lower profile strip Pu. However, an offset arrangement of the through-openings 11 in the longitudinal direction is also conceivable in the upper profile strip PO.

[0036] Fig. 6 illustrates in perspective view an upper profile strip Po of a U-shaped profile in (A) with the through-openings 11 and a lower profile strip Pu of a longitudinal profile in (B) with the alternatingly arranged indentations 12 and through-openings 11. The first leg of the U 1a and the second leg of the U 1b with the two facing indentations 3a and 3b as coupling sections of the slot-shaped receptacle 2 can also be seen.

[0037] Figure 7 shows a cross-sectional view of the longitudinal clip 5. The first clip leg 5a and the second clip leg 5b extend essentially vertically upwards from the base plate 7. The arrow-shaped retaining element 8, with its arrowhead 8a and two undercuts 8b and 8c, extends between the two clip legs. To the left and right of the arrow-shaped retaining element 8 are the receiving sections 14a and 14b of the longitudinal clip 5 for the mounting elements 9 of the reference 30. The first clip leg 5a and the second clip leg 5b each have a first projection 6a and 6b and a second projection 6c and 6d, respectively, with the second projection being located at the distal end of the clip legs 5a and 5b and the first projection 6a and 6b being located slightly below it. Between the first projection 6a or 6b and the second projection 6c or 6d there is a free space 13a or 6d.13b are formed, each serving to receive the distal end of the U-shaped legs 1a and 1b. The first projection 6a or 6b is approximately nose-like, and the second projection 6c or 6d is approximately pin-like. The projections 6a and 6b, and 6c and 6d, respectively, point outwards, away from each other. The second projection 6c or 6d is oriented obliquely upwards, thus forming the chamfer S', which, together with the arrowhead 8a, serves as an insertion aid for the mounting elements 9 of the reference 30 into the receiving section 14a or 14b, and as support for the hooks 9 by means of the reference tension, which are thus additionally secured in their final position. On its underside, the longitudinal clip 5 has further chamfers S” on the left and right sides to facilitate insertion into the longitudinal profile 1.

[0038] In Fig. 8, an upper and lower clip strip C (which are identical) of a longitudinal clip 5 are shown in perspective view according to (A), and a lateral clip strip Cs of a longitudinal clip 5 is shown in perspective view according to (B). In the lateral clip strip Cs, the incisions 15, which are alternately made in the clip strip and which serve to improve flexibility, can be seen in (B); i.e., for the side area of ​​the sofa or the armrest area (cf. Fig. 1). The first projections 6a and 6b and the second projections 6c and 6d of the first clip leg 5a and the second clip leg 5b, respectively, as well as the arrow-shaped retaining element 8 with the arrowhead 8a arranged between them, can also be seen.

[0039] Finally, Figure 9 (A) shows a side view of a lateral clip strip Cs, which is used particularly in curved side areas. The clip strip has alternating incisions 15 from the top and bottom, which ensure optimal flexibility. In section (B), it can be seen that the arrowhead 8a of the arrow-shaped retaining element 8 is not continuous in this area in order not to impair flexibility; i.e., the arrowhead is interrupted in sections. The same applies to the areas of the two clip legs 5a and 5b with the projections 6a and 6c and 6b and 6d, respectively. The incision 15 extends here to slightly above the base plate 7 of the longitudinal element 5.
