Description

[0001] Room dividers and methods for assembling a room divider

[0002] The invention relates to a room divider and a method for assembling a room divider.

[0003] Room dividers are well-known and serve to structure larger rooms and reduce acoustic and visual disturbances between different areas of a room.

[0004] Room dividers are, for example, placed on the floor or mounted on other furniture, especially desks.

[0005] Room dividers are known to exist that consist of a frame covered with a fabric to conceal the frame. However, such room dividers are complex to construct and therefore expensive.

[0006] The object of the invention is therefore to provide a room divider and a method for assembling a room divider that are visually appealing and cost-effective at the same time.

[0007] The problem is solved by a room divider with a frame and a connecting element. The connecting element has a central section and a tunnel section that forms the outer boundary of the central section and creates a tunnel. The frame has at least two support sections or at least one support section and a closure piece, wherein the at least two support sections or the at least one support section and the closure piece, when assembled, run within the tunnel section and, in the assembled state, form the shape of the room divider. The tunnel section has the shape of the room divider. The support sections are separate from each other in the unassembled state and are held together by the connecting element when assembled.

[0008] Because the support sections, or the support section and the locking piece, are held together by the covering in the assembled state, it is not necessary to equip the frame with snap connections and / or locking mechanisms. This reduces the cost of the room divider while simultaneously achieving an attractive appearance through the covering.

[0009] In particular, the tunnel section has the shape of the room divider in plan view when the reference is spread out on a flat surface.

[0010] In one embodiment, the shape of the room divider formed by the assembled support sections is a rectangle, a polygon, a circle, or an oval, in particular a rectangle or polygon with rounded corners. These shapes can be achieved with a simple frame construction.

[0011] To further reduce complexity and thus manufacturing costs, the frame can have exactly two support sections and / or be free of snap connections and / or locking mechanisms.

[0012] In one embodiment, the support sections each have at least one curved area and two legs, in particular wherein the legs run parallel to each other. In this way, the number of frame parts can be further reduced.

[0013] The thighs are particularly straight.

[0014] The two curved sections allow the beam section to have a U-shape, such as an irregular U-shape with legs of different lengths. The beam sections can be identical to each other and / or made of steel.

[0015] In one embodiment, the support sections are tubes, in particular tubes with a circular diameter, which further reduces manufacturing costs.

[0016] To simplify assembly, the support sections can be plugged into each other when assembled and / or the frame can have connecting pieces by means of which the support sections are aligned to each other.

[0017] For example, the connecting pieces have a reduced diameter compared to the support sections.

[0018] In one embodiment of the invention, the cover has a cover material that is a textile, imitation leather and / or leather.

[0019] In particular, the cover consists of the cover material, which makes the cover easy to manufacture.

[0020] In one design, the central section of the cover consists of exactly one layer of cover material, which further reduces costs.

[0021] Alternatively, the central section of the cover has two or more layers of the cover material, in particular wherein a filling material is provided between the two or more layers, so that the cover can achieve a further function, for example sound insulation.

[0022] The central section may also feature quilting and / or a decorative stitch. To further reduce manufacturing costs, the central section and the tunnel section may be made from the same covering material, in particular where the tunnel section is produced by folding and sewing the covering material to itself.

[0023] For example, they are made from the same material web.

[0024] In one embodiment, the tunnel section has an opening area in which the tunnel section has a fastening means, in particular a zipper, a hook-and-loop fastener and / or buttons, wherein the tunnel in the opening area is designed such that it can be formed or opened by means of the fastening means. The fastening means allows the tunnel to be opened to simplify assembly.

[0025] The buttons can also be snap fasteners, sliding buttons, or magnetic buttons.

[0026] To further simplify assembly, the fastening device can be located on the side of the tunnel section facing away from the central section and / or the opening area can extend over at least one corner of the shape of the room divider.

[0027] In one embodiment, the cover has exactly one tunnel, the tunnel section conceals the corners of the frame when assembled, and / or the tunnel section completely conceals the frame when assembled, thus increasing the value of the room divider.

[0028] The tunnel is, in particular, a topological torus.

[0029] In one embodiment, the tunnel section completely surrounds the central section, in particular where a seam is provided between the tunnel section and the central section, completely encircling the central section. In this way, the central section can be reliably fastened.

[0030] The problem is further solved by a room divider with a frame and a covering, wherein the covering has a central section and a tunnel section that bounds the central section externally. The covering has several separate material strips, each having a middle section and, at the ends of the middle section, an end section, forming a tunnel. The middle sections of the material strips together form the central section of the covering, and the end sections of the material strips together form the tunnel section of the covering. The frame has at least two support sections or at least one support section and a closure piece, wherein the at least two support sections or the at least one support section and the closure piece, in the assembled state, extend within the at least one tunnel section and, in the assembled state, form the shape of the room divider.The support sections are separate from each other in the unassembled state and held together by the cladding in the assembled state.

[0031] The features and advantages previously described for the room divider apply equally to this room divider and vice versa. In particular, this room divider can also have the features described above and / or the features of the dependent claims to claim 1.

[0032] In one embodiment, the middle sections of the material strips overlap each other and / or the material strips are arranged in different directions relative to each other, which further improves the stability of the room divider.

[0033] The problem is also solved by a method for assembling a room divider, in particular as described above, which has a frame with support sections and a reference with a central section and a tunnel section. The method comprises the following: a. providing a composite first subsection of the frame from at least one support section, b. subsequently inserting the first subsection into the tunnel section of the reference so that the tunnel section is completely traversed by the first subsection, c. subsequently assembling the entire frame from the first subsection and at least one further support section or a closure piece, d.Subsequent movement of part of the reference from the first subsection to at least one further support section, such that at least one further support section runs completely through the tunnel section, so that the support sections are held together by the reference.

[0034] In one embodiment, the composite first subsection consists of a single support section of the frame that is provided, or of several support sections of the frame that have been previously assembled and are provided as an assembly.

[0035] To increase the stability of the room divider, a fastening device of the tunnel section can be closed after the movement of the part of the reference from the first sub-section to the further support section has taken place.

[0036] Further advantages and features of the invention will become apparent from the following description and from the accompanying drawings, to which reference is made. In the drawings, Fig. 1 shows an embodiment of a room divider according to the invention in a fully assembled front view.

[0037] Figs. 2, 3 show the room divider according to Figure 1 in perspective view and top view respectively.

[0041] Fig. 7 shows the room divider in a state during assembly,

[0042] Fig. 8 shows a flowchart of a process according to a

[0043] An embodiment of the invention for assembling a room divider,

[0044] Fig. 9 shows a room divider according to a second embodiment of the invention in front view, and

[0045] Fig. 10 shows the frame of a room divider according to a third embodiment of the invention in perspective view.

[0046] Figure 1 shows a room divider 10 in front view.

[0047] In the illustrated embodiment, the room divider 10 has a rectangular shape with rounded corners. The height of the room divider 10 is between 1 m and 2 m, particularly 1.50 m. The room divider 10 is also between 50 cm and 1 m wide.

[0048] The room divider 10 serves as a visual barrier between two areas of a room that need to be separated, for example, between desks in an office. For this purpose, the room divider 10 can be positioned vertically, as shown in Figure 1. This can be done, for example, using a stand into which the room divider 10 is inserted, or legs that are attached to the room divider 10.

[0049] The room divider 10 has a cover 12 and a frame 14.

[0050] In the illustrated embodiment, the frame 14 is completely concealed by the cover 12 in the assembled state.

[0051] Figures 2, 3 and 4 show a perspective view, a top view and a section view through the room divider 10.

[0052] Figure 5 shows an enlargement of the sectional view according to Figure 4 in the area of ​​a frame.

[0053] Cover 12 is made of a cover material that is, for example, a textile, imitation leather and / or leather. In particular, cover 12 consists of the cover material.

[0054] Reference 12 has a central section 16 and a tunnel section 18.

[0055] The central section 16 covers, as seen in a top view according to Figure 1, the vast majority of the area of ​​the room divider 10, namely the area inside the frame 14.

[0056] Tunnel section 18 borders central section 16. For example, central section 16 transitions into tunnel section 18.

[0057] The tunnel section 18 surrounds the central section 16 on its outer surface, where "outer surface" in this context refers to the plane defined by the room divider 10. In Figure 1, this is, for example, the image plane. For instance, as in the embodiment shown, the tunnel section 18 completely surrounds the central section 16, so that the central section 16 is entirely enclosed by the tunnel section 18.

[0058] The central section 16 is single-layered and therefore consists of exactly one layer of the covering material.

[0059] It is also conceivable that the central section 16, as indicated by the dashed lines in Figure 5, consists of two layers of the covering material. A filler material can be provided between these layers.

[0060] In this case, it is also conceivable that the two layers of the central section 16 are connected by raking or quilting.

[0061] It is also conceivable that the central section 16 has more than two layers.

[0062] For example, tunnel section 18 is made from the same reference material as central section 16, as shown in the illustrated embodiment.

[0063] The tunnel section 18 forms a tunnel 20 for the frame 14 and, when the reference 12 is spread out on a flat surface, has the shape of the room divider 10. In the illustrated embodiment, the tunnel section 18 is therefore also rectangular with rounded corners.

[0064] It is conceivable that the shape of the room divider 10 is different, for example, a different polygon.

[0065] For example, as in the illustrated embodiment, the tunnel section 18 has exactly one continuous tunnel 20. This tunnel completely surrounds the central section 16. In this and other embodiments, the tunnel 20 is closed off from the central section 16.

[0066] Even if the central section 16 has several layers, tunnel 20 is separated from these layers.

[0067] For example, this is done by means of a seam 22 which is located between the tunnel section 18 and the central section 16 and which completely surrounds the central section 16.

[0068] As can be seen particularly well in Figure 5, the tunnel section 18 can be made from the same covering material as the central section 16. For example, the tunnel section 18 is produced by folding the covering material over itself at the edges and then attaching it to itself with a seam 22.

[0069] In this way, tunnel 20 is created, which, as previously described, is separated from the central section 16 by seam 22 and completely surrounds the central section 16.

[0070] Tunnel 20 and tunnel sections 18 are also closed off to the outside, i.e. on the side facing away from central section 16.

[0071] In certain areas of tunnel section 18, which are hereinafter referred to as opening areas 24, tunnel section 18 has a fastening device 26.

[0072] The fastening element 26 is particularly reusable, such as a zipper, a hook-and-loop fastener, or buttons. The term "buttons" also includes snap fasteners, slide fasteners, or magnetic buttons.

[0073] The fastening element 26 is indicated by a dashed line in Figure 5 because it is not present over the entire circumference of the room divider 10. For example, the fastening element 26 is located on the side of the tunnel section 18 facing away from the central section 16.

[0074] However, it is also conceivable that the fastening device 26 is arranged at other locations along the circumference of the tunnel 20.

[0075] The fastening device 26 can be opened so that the tunnel 20 is open.

[0076] In this open state, for example, frame 14 can be inserted into tunnel 20.

[0077] If the fastening device 26 is closed, the tunnel 20 is also closed.

[0078] Tunnel 20 is then completely closed and, topologically speaking, forms a torus.

[0079] For example, reference 12 has exactly one opening area 24.

[0080] The opening area 24 in the illustrated embodiment extends, as indicated by the dashed line in Figure 2, completely along the lower edge of the room divider 10, over both lower corners of the room divider 10 and a section along the sides.

[0081] Figure 6 shows the frame 14 in its unassembled state. The frame 14 has two support sections 28, which are two separate components.

[0082] The support sections 28 are, for example, as in the illustrated embodiment, tubes with a circular diameter. For example, the diameter is 22 mm. The material of the support sections 28 is, for example, steel. The support sections 28 are each manufactured in one piece. For simplification, the support sections 28 can be identical to each other.

[0083] In the embodiment shown, the frame 14 has exactly two support sections 28. However, it is also conceivable that the frame 14 has more than two support sections 28.

[0084] The support sections 28, for example, have a straight base 30, two straight legs 32, and two curved sections 34. In the assembled state, the base 30 forms the lower and upper sides of the room divider 10. The curved sections 34 adjoin the base 30 on both sides and each form an angle of 90°. One of the legs 32 extends from each of the curved sections 34, with the legs 32 running parallel to each other.

[0085] The legs 32 can be of the same length, so that the support sections 28 each have a uniform U-shape.

[0086] In the illustrated embodiment, however, the two legs 32 are of different lengths, so that the support sections 28 have an irregular U-shape.

[0087] One of the legs 32 has a connecting area 36 at its end, which is not connected to the curved area 34.

[0088] The connecting area 36 has a smaller diameter than the leg 32.

[0089] The diameter of the connection areas 36 is selected such that they can engage in the leg 32 of the other support section 28 that does not have a connection area 36. In the illustrated embodiment, the connection areas 36 are provided at the end of the longer leg 32 and have a diameter that corresponds to the inner diameter of the shorter leg 32.

[0090] It is conceivable that the frame 14 also has connecting pieces 38 (indicated by dashed lines in Figure 6). In this case, the legs 32 do not have connecting areas 36.

[0091] The connecting pieces 38 have a reduced diameter so that they can engage in the legs 32 of the support sections 28 and align them with each other.

[0092] In both cases, the frame 14 is designed without locking connections or locking mechanisms that could fasten the two support sections 28 together.

[0093] As can be seen from Figure 6, when the two support sections 28 are assembled, the frame 14 has the shape of the room divider 10. The frame 14 thus also forms the shape of the room divider 10, in this example a rectangle.

[0094] Frame 14 is also a topological torus.

[0095] As can be seen from Figures 4 and 5, the support sections 28 run completely within tunnel section 18.

[0096] In the illustrated embodiment, the tunnel section 18 completely covers the frame 14 and thus also the corners of the frame 14.

[0097] As can be seen in Figures 1 and 2, the frame 14 is no longer visible from the outside when the room divider 10 is fully assembled. Furthermore, the support sections 28 are held together by the support 12, which, as previously described, also has the shape of the room divider 10 and thus the corresponding dimensions. The assembly of the room divider 10 can be carried out using the procedure schematically depicted as a flowchart in Figure 8.

[0098] Initially, a first subsection 40 of frame 14 will be provided at S1.

[0099] If the frame 14, as in the first embodiment, consists of exactly two support sections 28, the first subsection 40 of the frame 14 corresponds to one of the support sections 28. This is already assembled or any connecting piece 38 can be inserted into the support section 28.

[0100] Subsequently, at S2, the first subsection 40 is introduced into tunnel section 18 of reference 12.

[0101] To insert the first subsection 40, the fastening device 26 of tunnel section 18 may need to be opened, if this has not already been done.

[0102] The insertion proceeds to the point where tunnel section 18 is completely traversed by the first subsection 40, so that reference 12 is fully threaded onto the first subsection 40. For this to happen, it may be necessary to gather reference 12.

[0103] The entire frame 14 is then assembled (S3). For this purpose, the first subsection 40 is connected to the remaining support sections 28 of the frame 14, i.e., to at least one further support section 28.

[0104] If necessary and not already done, the additional connecting pieces 38 can be used.

[0105] In the first embodiment, the first section 40 is thus inserted into another support section 28, so that the entire frame 14 is assembled. This state is shown in Figure 8.

[0106] Subsequently, part of the reference 12 is moved from the first subsection 40 to at least one further support section 28.

[0107] In this process, the further support section 28 is inserted into the tunnel section 18 of the reference 12, or the tunnel section 18 is stretched by tensioning the reference 12, so that it encompasses at least one further support section 28 and finally the entire frame 14.

[0108] At least one further support section 28 then also runs completely through tunnel section 18 (S4).

[0109] In this process, the entire reference 12 is stretched, so that the central section 16 is also stretched and enlarged, so that the reference 12 finally completely covers the entire frame 14 and also the area enclosed by the frame.

[0110] The fastening device 26 is then closed (S5).

[0111] The room divider 10 is now fully and reliably assembled and can now be set up.

[0112] The room divider 10 is therefore extremely simple in construction, as the frame consists of only a few parts and, in particular, requires no complicated snap connections or elaborate locking mechanisms. At the same time, the frame is visually very appealing, since the central section can be designed in almost any way and is tensioned.

[0113] Figure 9 shows a further embodiment of a room divider according to the invention, which essentially corresponds to the first embodiment of the room divider 10. Therefore, only the differences will be discussed below, and identical and functionally equivalent parts are provided with the same reference numerals. The illustration in Figure 9 corresponds to the illustration in Figure 1.

[0114] The frame 14 of the room divider 10 corresponds to the frame 14 of the room divider 10 of the first embodiment.

[0115] However, the room divider 10 according to the second embodiment has a different reference 12 to

[0116] The covering 12 of the room divider 10 according to the second embodiment has several separate material strips 42 which together form the covering 12.

[0117] The material strips 42 are elongated and have a width that is less than the width of the room divider 10.

[0118] The material strips 42 each have a middle section 44 with the width of the material strips 42, at the end faces of which an end section 46 is provided.

[0119] The material strips 42 are, in particular, rectangular.

[0120] However, it is also conceivable that the material strips 42 have other geometric shapes, for example, trapezoidal shapes.

[0121] The end sections 46 each form a tunnel 48, which extends transversely to the longitudinal direction of the middle section 44.

[0122] The length of the tunnel 48 thus corresponds to the width of the material strip 42.

[0123] The end sections 46 of the material strips 42 can be designed in the same way as described for the support sections 28 of the first embodiment and shown in Figure 5.

[0124] The length of the material strips 42 in the longitudinal direction of the central section 44 corresponds either to the height of the room divider 10 or to the width of the room divider 10. Therefore, in the second embodiment shown in Figure 9, material strips 42 of two different lengths are present: longer material strips 42 with a length corresponding to the height of the room divider 10, and shorter material strips 42 with a length corresponding to the width of the room divider 10.

[0125] In the assembled state, the longer material strips 42 extend vertically, i.e. in the longitudinal direction of the space divider 10, and the shorter material strips 42 extend horizontally, i.e. along the width of the material strip 42.

[0126] The shorter material strips 42 thus run perpendicular to the longer material strips 42, so that the material strips 42 are arranged in different directions relative to each other.

[0127] The middle sections 44 of the material strips 42 overlap with each other, in particular the middle sections 44 of the shorter material strips 42 overlap with the middle sections 44 of the longer material strips 42.

[0128] For example, the material strips 42 are interwoven.

[0129] The middle sections 44 thus together form the central section 16 of reference 12, and the end sections 46 in this way form the tunnel section 18 of reference 12.

[0130] In contrast to the first embodiment, it is conceivable that the tunnel section 18 no longer covers the corners of the frame 14. However, this can also be achieved by using suitably selected material strips 42. Thus, complete covering of the frame 14 by the covering 12 is also possible when using material strips 42.

[0131] The material strips 42, which are made of different materials and / or in different colors, can also be used to create a visually appealing room divider 10. The frame 14 is designed in the same simple manner as described in the first embodiment.

[0132] The assembly of the room divider 10 according to the second embodiment is also carried out as described for the first embodiment. It should be noted that when the first subsection 40 is inserted into the tunnel section 18, all end sections 46 or tunnel 48 of the material strips 42 are threaded over the first subsection 40.

[0133] To simplify the process, the material strips 42 can first be laid out in the desired pattern or arrangement before being threaded onto the first section 40.

[0134] Figure 10 shows a third embodiment of the room divider 10, in which only the frame 14 is shown.

[0135] In this embodiment, the frame 14 consists of only one support section 28 and one closure piece 50.

[0136] The support section 28 is completely closed except for an opening 52, i.e. the support section 28 almost completely surrounds the area inside the frame 14.

[0137] In the assembled state, a locking piece 50 is inserted into the opening 52, which closes the frame 14.

[0138] The closure piece 50 can be identical or similar to a connecting piece 38 of the previous embodiments.

[0139] For assembly, the support section 28 is provided as the first subsection 40, and then the cover 12, as described for the first embodiment, is threaded through the opening 52 onto the support section 28. Subsequently, the closure piece 50 is inserted into the opening 52, and part of the cover 12 is also pulled over the closure piece 50. Then the fastening device 26 can be closed.

[0140] Naturally, the features of the different designs can be combined in any way desired.
