Description

[0001] The present invention relates to an upholstered furniture combination according to the preamble of the main claim. Such upholstered furniture combinations comprise a first base frame, which has a longitudinal extension, with at least one first side armrest, one first backrest, and one first seat section that can be fixed to the base frame. Furthermore, a second base frame is also used, which has a longitudinal extension and comprises at least one second side armrest, one second backrest, and one second seat section that can be fixed to the base frame. Such upholstered furniture combinations can be configured as corner units with respect to the base frame.

[0002] Upholstered furniture combinations that can also be configured as corner units are known from the prior art. These combinations are typically designed as either left- or right-hand corner units to ensure optimal integration into either a left- or right-hand corner. This requires custom-designed and manufactured pieces for either the left or right corner. Furthermore, if an ottoman is to be used on the left or right side of the unit, a simple switch between a left- and right-hand corner unit is not possible, as the ottoman has a wide side arm integrated into its frame.Therefore, this basic frame cannot be used in any other way for a corner upholstered furniture combination.

[0003] Further details of upholstered furniture are known from the documents US 2011 / 0 101 763 A1, CA 2 424 626 A1 and DE 81 21 535 U1.

[0004] However, today's mobility of the population also requires more frequent moves, which also involves changing living spaces, so furniture should be adaptable to the respective living situation.

[0005] The object of the present invention is to overcome, at least partially, the aforementioned disadvantages of the prior art. In particular, it is an object of the present invention to create an upholstered furniture combination that can be easily adapted to different living space conditions. It is especially advantageous if the upholstered furniture combination can be adapted to the various corner areas in the living space.

[0006] The present problem is solved by an upholstered furniture combination with the features of the main claim, in particular from the characterizing part. Further features and details of the invention will become apparent from the respective dependent claims, the description, and the drawings.

[0007] The upholstered furniture combination according to the invention comprises a first base frame with a longitudinal extension and a second base frame, also with a longitudinal extension, which are arranged at angles to each other, in particular at right angles to each other. Additionally, the first base frame has at least one first side armrest, one first backrest, and one first seat section, which can be fixed to the base frame. The second base frame also has at least one second side armrest, one second backrest, and one second seat section.

[0008] Seat section. To increase the seating-reclining comfort of the upholstered furniture combination, the second base frame can be designed as an ottoman seat section. To make the first side armrest detachable from the first base frame, it can be attached to a first head end of the first base frame by a first connecting element. Furthermore, the second base frame can be attached to a second head end of the first base frame by a second connecting element. Thus, the first side armrest and the second base frame are arranged at the two head ends of the first base frame. According to the invention, it is now provided that the first side armrest is interchangeable with the second base frame, so that the first side armrest can also be attached to the second head end of the first base frame, and the second base frame can also be attached to the first head end of the first base frame.In other words, the first side armrest can be attached to the second base frame at the opposite end of the first base frame. This design makes it possible to easily configure the upholstered furniture combination according to the invention as either a left-hand corner sofa or a right-hand corner sofa. Thus, the first base frame itself always remains the same; only the arrangement of the first side armrest can be changed or exchanged with the arrangement of the second base frame at the end of the first base frame.

[0009] For this purpose, it is advantageously provided that the first connector for attaching the first side panel to the first end of the first base frame functions identically to the second connector for attaching the second base frame to the second end of the first base frame, in order to facilitate the exchange of the first side panel with the second base frame on the first base frame. In other words, the first connector is designed identically to the second connector so that a simple exchange of the first side panel with the second base frame is possible via the connectors. Ideally, the connectors themselves are designed as hook elements, screw elements, or snap-in elements to make the exchange particularly easy. Preferably, the reconfiguration of the corner upholstered furniture combination (from left to right or vice versa) should be possible without tools.

[0010] Furthermore, the invention may provide that at least the backrest or the first seat section is permanently attached to the first base frame. This fixed attachment of the backrest and / or the first seat section to the base frame allows for a particularly stable design of the upholstered furniture combination. It also facilitates the assembly of such an upholstered furniture combination. It is also conceivable that the first backrest and / or the first seat section forms an integral part of the first base frame. In other words, the first backrest and / or the first seat section cannot be removed from the first base frame without being destroyed.

[0011] It is also conceivable that the second side arm is permanently attached to the second base frame to form the aforementioned ottoman seat. It is also conceivable that the second side arm forms an integral part of the second base frame to increase its stability. In this case, the second side arm can only be detached from the first base frame by destroying it.

[0012] To further increase the range of applications for the upholstered furniture combination according to the invention, it can be provided that a pull-out box (or pull-out trolley) is attached to the first base frame, which, when retracted, is located under the first seat section. Blankets, pillows, or the like can be stored in this pull-out box. In this case, the pull-out box is designed as a drawer with additional storage space.

[0013] It is also conceivable that the pull-out drawer includes an extension section (also called a lifting section), which is height-adjustable, to create a level surface with the first seat section when the pull-out drawer is extended. By using this extension section, the upholstered furniture combination according to the invention can be transformed into a seat-lounger combination.

[0014] It can also be designed so that, when the pull-out drawer is extended, a chaise longue combination is formed with a corresponding sleeping surface on both the seat and the extension section. Ideally, the resulting sleeping surface is level to ensure optimal comfort. A topper can also be used on this sleeping surface to bridge the gaps between the seat and the extension sections. When extended, the extension section can thus be raised to the same height as the seat sections from the two base frames to create the uniform sleeping surface.

[0015] Furthermore, it is conceivable that when the pull-out drawer is retracted, or even without a pull-out drawer, a corner upholstered furniture combination with corresponding seating surfaces on the seat sections is created, optionally configured on the left or right side. Overall, this allows for a highly versatile upholstered furniture combination that can be adapted to individual living spaces with minimal effort and without the use of tools.

[0016] Within the scope of the invention, it is possible for at least the second seat section or the second backrest to be removable from the second base frame. This design allows the ottoman seat section to be positioned on either side of the first base frame, rotated 180° (along the longitudinal axis L2). Furthermore, the second seat section can be attached to the second base frame with a retaining element, and / or the second backrest can also be attached to the second base frame with a fixing element. The use of the retaining elements and / or fixing elements enables a simple reconfiguration of the second base frame with the second seat section and the second backrest. It is conceivable that the retaining element and / or fixing element could be designed as a hook element, screw element, or locking element.A particularly simple and stable design uses a screw-in element, where screws or threaded rods extend from the underside of the second seat section, aligning with holes in the second base frame and being screwed to the second base frame from below with nuts, ideally wing nuts, without the need for tools. The fixings for attaching the second backrest can also be designed as screws or threaded rods, which can be fastened to the second seat section or the second base frame using threaded nuts, ideally wing nuts. A kinematic reversal of the screw and nut arrangement is also conceivable.

[0017] As previously mentioned, the second backrest can either be attached to the second seat section using fasteners, or the second backrest can be permanently connected to the second seat section. This combined unit, consisting of the second seat section and the second backrest, can be attached to the second base frame using the aforementioned fasteners. The advantage of the combined unit lies in its particularly stable construction. However, the necessary change of direction of the second seat section relative to the second base frame can be more difficult because the combined unit is correspondingly heavier than two separate parts (second seat section and second backrest structurally separate). This change of direction of the second seat section on the second base frame is necessary to allow the ottoman seat section to be positioned on the left or right side of the first base frame.

[0018] Within the scope of the invention, it is further conceivable that the second seat section (with or without the second backrest) can be rotatably attached to the second base frame from at least a first position by approximately 180° to a second position. Ideally, the existing retaining devices can be used for both positions. This allows for easy replacement of the second seat section on the second base frame, particularly without tools.

[0019] As previously stated, the second seat section and the second backrest can be permanently attached to each other and preferably form a monolithic component. This monolithic component was previously mentioned as a combination part, which is of particularly robust construction.

[0020] To improve the stability of the second base frame, the second side armrest forms a support edge for the second seat section. Ideally, the second backrest is permanently attached to the second base frame. This allows the second seat section to be embedded in a recess in the second base frame formed by the support edge of the second side armrest. Preferably, the second side armrest extends laterally beyond the second seat section, thereby increasing both seating and reclining comfort and significantly improving stability (especially of the ottoman seat section). Ideally, the second side armrest extends the entire length of the second base frame, ensuring that the second seat section rests against the aforementioned support edge along its entire length.This design means that not all the necessary holding forces acting on the second seat part have to be transferred from the holding means to the connection with the second base frame, since a large part of the forces can also act on the second base frame via the support edge.

[0021] To further improve the comfort of the (corner) upholstered furniture combination according to the invention, it can be provided that at least the first or second backrest is at least partially adjustable in its orientation. This allows the existing backrests to be adapted to the user's desired sitting or reclining position. Furthermore, it is conceivable that at least the first or second backrest is at least partially upholstered, which also improves user comfort. It is also possible that at least the first or second side armrest is at least partially upholstered. Ideally, the upholstery of the backrests is identical to that of the side armrests, thereby achieving both a pleasing appearance of the upholstered furniture combination and increased comfort.

[0022] To allow for adjustable seat height of the upholstered furniture combination, at least the first or second base frame may be equipped with adjustable feet to support the furniture on the floor. If height adjustment is not desired, simple glides can be used instead of feet.

[0023] As already described in the invention, the upholstered furniture combination can easily be converted from a left-hand corner configuration to a right-hand corner configuration. Naturally, the reverse conversion of the corresponding corner configuration is also conceivable. The corresponding (tool-free) conversion, which is particularly easy to perform – even for a layperson – is explained in detail in the following description of the figures.

[0024] Furthermore, it should be mentioned that the present invention is also directed to the described conversion method of the upholstered furniture combination according to the invention.

[0025] The preceding explanation described the invention using various examples. Naturally, individual features of the invention can be freely combined with one another, provided this is technically feasible, without departing from the scope of the present invention.

[0026] According to the invention, the features from the description and the claims can be essential to the invention individually as well as in conceivable combinations. Further measures improving the invention are described in more detail below, together with a description of preferred embodiments in various applications of the invention, with reference to the figures:

[0027] They show: Fig. 1 Three-dimensional view of the upholstered furniture combination according to the invention with a retracted pull-out box, Fig. 2 comparable upholstered furniture combinations made of Fig. 1 with an extended pull-out drawer and a raised extension part, Fig. 3 + Fig. 4. Indicated conversion of the upholstered furniture combination from Fig. 1, Fig. 5 fully converted upholstered furniture combinations made of Fig. 1, Fig. 6 Exploded view of the upholstered furniture combination according to the invention made of Fig. 1, Fig. 7 comparable upholstered furniture combinations made of Fig. 1, however with a structurally separate second backrest from the second seat section, Fig. 8 comparable to Fig. 4, however with a structurally separate second backrest and the second seat section, Fig. 9a + Fig. 9b possible retaining means between the second seat part and the second base frame of the upholstered furniture combination according to the invention, Fig. 10a + Fig. 10b Schematic side view of the upholstered furniture combination according to the invention made from the Fig. 9a and Fig. 9b and Fig. 11a + Fig. 11b comparable to the Fig. 10a and Fig. 10b, however, the second backrest is connected to the second seat section via fixing elements.

[0028] In the following figures, the same reference numerals are used for the same technical features even for different embodiments.

[0029] In the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 to Fig. Figure 6 shows an upholstered furniture combination 10 according to the invention, which can be converted from a right-hand corner upholstered furniture combination 10 to a left-hand corner upholstered furniture combination 10 (and vice versa). For this purpose, the upholstered furniture combination 10 has at least a first base frame 20 and a second base frame 40, which are arranged transversely to each other, preferably at a 90° angle to each other. The first base frame 20 has a longitudinal extension L1, just as the second base frame 40 has a longitudinal extension L2 (see Figure 6). Fig. 1 or Fig. 6) Advantageously, a first seat section 21 and a first backrest 23 are fixedly arranged on the first base frame 20, ideally forming an integral part of the first base frame 20. Furthermore, a pull-out box 20.1 can be arranged on the first base frame 20, which is essentially covered by the first seat section 21 when retracted S (see Figure 6). Fig. 1) To make the upholstered furniture combination 10 convertible, a first side arm 22 can be attached to the first head end 20.3 (first interchangeable side 20.3) of the first base frame 20 via connecting elements 13. Furthermore, the second base frame 40 can also be attached to the second head end 20.4 (second interchangeable side 20.4) of the first base frame 20 via connecting elements 13.

[0030] In the Fig. 1, Fig. 2 to Fig. 3 The first side armrest 22 is arranged on the left side of the first head end 20.3 of the first base frame 20 via connecting elements 13. At the second head end 20.4 of the first base frame 20, the second base frame 40 is attached via connecting elements 13. To simplify the exchange of the first side armrest 22 with the second base frame 40 on the first base frame 20, the respective connecting elements 13 are preferably of identical design. As can be seen from the Fig. 3 and Fig. As shown in Figure 4, the conversion of the right-hand corner upholstered furniture combination 10 into the left-hand corner upholstered furniture combination 10 can be achieved by exchanging the first side armrest 22 on the first base frame 20 with the second base frame 40. This involves exchanging the first seat section 21 and the second base frame 40 at the head end points 20.3 and 20.4 of the first base frame 20.

[0031] Furthermore, a modification to the second base frame 40 is also necessary to completely transform the upholstered furniture combination 10. For this purpose, a second seat section 41 and a second backrest 43 are arranged on the second base frame 40. The second base frame 40 also has a second side armrest 42, which forms an integral part of the second base frame 40. In this case, the second base frame 40, together with the second seat section 41, the second side armrest 42, and the second backrest 43, forms a so-called ottoman seat section. To ensure that the second backrest 43 is correctly positioned on the first base frame 20 after the second base frame 40 is replaced, the second seat section 41 and the second backrest 43 are interchangeably arranged on the second base frame 40 via retaining elements 14 (see below). Fig. 9) Now that the second base frame 40 is attached from the head end 20.4 to the other head end 20.3 of the first base frame 20, the second seat section 41 and the second backrest 43 must be rotated (by 180°) on the second base frame 40, as shown in Fig. 4 indicated by the rotation arrow. After the second base frame 40 has also been completely converted and attached to the first base frame 20, the right-hand corner upholstered furniture combination 10 has become the left-hand corner upholstered furniture combination 10, as shown in Fig. 5 shown, originated.

[0032] In the Fig. Figure 6 shows the essential components of the upholstered furniture combination 10 according to the invention, namely the first base frame 20 with the removable first side armrest 22, the second base frame 40 with the removable second seat section 41 and the second backrest 43 arranged thereon, in an exploded view. Only the additional cushion 11 made of Fig. One is missing.

[0033] In the Fig. Figure 2 further shows the upholstered furniture combination 10 according to the invention, comprising a pull-out box 20.1 and an extension part 20.2 arranged thereon. In the Fig. 2 is - in contrast to the Fig. Figure 1 shows the pull-out box 20.1 in its extended state L with the extension section 20.2 raised. This upholstered furniture combination 10 forms a large sleeping surface 16, in which all seat sections 21, 41 and the extension section 20.2 are essentially at the same level and form the sleeping surface 16. This sleeping surface 16 can additionally be covered with a topper (not shown).

[0034] As already mentioned, the conversion of the upholstered furniture combination 10 according to the invention is carried out from the Fig. 1 in the Fig. 3 and Fig. 4 shown graphically, so that the upholstered furniture combination 10 consists of Fig. 5 results.

[0035] In the Fig. 7 and Fig. 8 is a variant of the upholstered furniture combination 10 according to the invention. Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 to Fig. Figure 6 shows the essential difference being that the second seat section 41 is not designed as a single unit with the second backrest 43, but rather is structurally separate from the second backrest 43. The conversion of this upholstered furniture combination 10 is essentially the same as the conversion described previously. Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 to Fig. 6, wherein the connection of the second seat part 41 with the second backrest 43 can additionally take place when the second base frame 40 is rotated.

[0036] In the Fig. 11a and Fig. Figure 11b shows the fixing means 15 for connecting the second backrest 43 to the second seat section 41 in more detail. These can consist of a screw 17 or screw rod 17 and a corresponding nut 18. Advantageously, the screws 17 can be attached to the second seat section 41, which, when attached to the second backrest 43, mechanically interact with the wing nuts 18 shown to form a secure connection between the two components 41 and 43. Washers 19 can also be used in the screw connection to improve the mechanical strength of the connection.

[0037] In the Fig. 9a and Fig. Figure 9b shows in detail the fastening elements 14, which serve to create a secure connection between the second base frame 40 and the second seat part 41. Here too, the fastening elements 14 can consist of screws or threaded rods 17, which interact mechanically with corresponding nuts or wing nuts 18 to create the secure connection between the second base frame 40 and the second seat part 41. Additionally, washers 19 can be used with both the fastening element 14 and the fixing element 15.

[0038] In the Fig. 10a and Fig. 10b is a side view, partially in section - comparable to the illustrations from the Fig. 9a and Fig. 9b - shown.

[0039] How well from the Fig. As can be seen in Figures 9a to 10b, the screws 17, which serve as retaining elements 14, interact with corresponding holes in the second base frame 40. When the second seat section 41 is rotated (by 180°), the same holes can be used for the screws 17, since they are arranged symmetrically on the upholstered furniture combination 10. Thus, the upholstered furniture combination 10 shown in the exemplary embodiments can be converted by a user without tools.

[0040] Even those in the Fig. 2 and Fig. The six indicated connecting elements 13 can be designed as hook elements, screw elements, or snap-fit ​​elements. It is also conceivable that these connecting elements 13, similar to the holding elements 14 and fixing elements 15, consist of screws 17 and nuts 18.
