Description

[01] Field of technology

[02] The utility model relates to the furniture industry, namely to an element for fastening a flexible upholstery material to a metal frame of upholstered furniture. The utility model can be used for fixing upholstery fabric or leather upholstery on the frame of a sofa or armchair.

[03] State of the art

[04] The closest analogue of the utility model is the fastening element of the fabric upholstery to the furniture frame, disclosed in the RF utility model patent RU 202033, 07/28/2020. The fastening element is made of a polymer sheet and has a bent part, which engages with the protruding part of the profile, and a flat part, which is connected to the edge of the fabric cover.

[05] The main disadvantage of the analogue is the difficulty of assembling furniture, due to the fact that when attaching the upholstery, it is necessary to fix the edge of the material on a rigid fastener. If the fixing material is soft enough, this can lead to deformation and the element jumping off the profile when tension is applied. If the fastening material is rigid, it becomes difficult to break through to attach the upholstery to it. Everything creates difficulties in assembling furniture.

[06] Disclosure of the Invention

[07] The main technical problem, which the utility model is aimed at solving, is the complexity of the production of upholstered furniture with a metal frame.

[08] The technical result of the utility model is to simplify the fastening of the upholstery material to the frame.

[09] The specified technical result is achieved in the claimed utility model due to the fact that the fastening element of the flexible upholstery material to the metal frame of upholstered furniture is made of sheet polymeric material and includes a bent part, made with the possibility of engagement with the protruding part of the frame, and a flat part, made with the possibility of attaching to the upholstery material. In this case, the bent part is made of a polymeric material capable of retaining its shape during deformation, and the flat part is made of a softer polymeric material in relation to the polymeric material of the bent part.

[010] In particular embodiments of the utility model:

[011] - the folded part is formed by a folded edge of the sheet material, which runs parallel to the main part to form a gap;

[012] - the flat part is made with the possibility of fastening to the upholstery material by means of staples or rivets or seams;

[013] - the bent part is made of suspension polyvinyl chloride, and the flat part is made of polyvinyl chloride compound.

[014] Unlike analogues, the claimed fastening element is composed of two different materials. The bent part (for hooking on the profile) is made harder and is able to retain its shape under load, and the flat part (for attaching to the fabric upholstery) is softer. This allows, on the one hand, to preserve the functionality (rigidity) of the fastening element, and on the other hand, to facilitate the connection of the fastening element with the upholstery, since it is much easier to break through the soft polymer material.

[015] Brief Description of the Drawings

[016] The utility model is illustrated by drawings, where:

The figure 1 shows a fragment of upholstered furniture on a metal frame;

Figure 2 shows a cross section of a piece of furniture;

The figure 3 shows a part of the section of the fragment at the attachment point of the upholstery;

The figure 4 shows the tubular frame profile;

The figure 5 shows the cross section of the profile;

Figure 6 shows the claimed upholstery fastening element

The figure 7 shows the cross section of the fastening element;

The figure 8 shows the mount assembly;

Figure 9 shows a cross section of the mount.

[017] Structural elements are indicated in the figures by the following positions:

1 - furniture frame,

2 - tubular profile (element) of the frame,

3 - lamella,

4 - soft element,

5 - upholstery material (coating),

6 - upholstery fastening element,

7 - the main part of the profile,

8 - protruding part of the profile,

9 - bent part of the fastening element,

10 - flat part of the fastening element.

[018] The implementation of the invention

[019] Furniture using the claimed utility model includes a metal frame (1) formed using tubular profiles (2) (tubular elements), lamellas (3) installed in the frame, soft elements (4) placed on the frame, and upholstery material (5) stretched over soft elements.

[020] The upholstery fastening unit (5) is formed by a tubular profile (2) (Fig. 4, 5) and fastening elements (6) placed on it (Fig. 6, 7).

[021] The tubular profile (2) has a closed configuration of a complex shape and consists of a main part (7), which in cross section has the shape of a rectangle, in particular a square, as well as a protruding part (8), which is formed by two closed walls of a closed contour, one of which is a continuation of the side of the main part (7). In other words, the cross-sectional profile has a hollow area (main part 7) which merges into a flat area (raised part 8). The protruding part (8) of the profile (2) is preferably directed inward along the plane of the frame (1) (see Fig. 3). Conventional manufacturing methods such as rolling, pressing or casting can be used to produce a tubular profile of complex shape.

[022] The claimed attachment element (6) of the upholstery material (5) is made of a single polymer sheet and is formed by a bent part (9), which passes into a flat part (10). The bent (9) (hook-shaped) part is formed by the bent edge of the sheet material, which runs parallel to the main part with the formation of a gap in which the protruding part (8) of the profile (2) is located. The bent part (9) of the sheet is made of a rigid polymeric material, which has the ability to retain its shape when the fastening element (6) is loaded. For example, polyvinyl chloride suspension brand SI-67 can be used. The flat part (10) of the sheet of the element (6) is used for fastening to the upholstery material (5) and is made of a polymer material that is softer in relation to the part (9). For example, a rubber-like material can be used, in particular polyvinylchloride compound grade Sh-62-0. Seam, rivets, staples and other elements can be used to fasten the upholstery. The fastening element (6) can be made by joint casting of two different polymeric materials, in which parts (9) and (10) are combined into a single sheet.

[023] Assembly of furniture using the claimed fastening element is carried out as follows.

[024] From pre-formed profiles (2) of the claimed design, a metal frame (1) is assembled into which lamellas (3) are installed. Soft elements (4) are laid on the resulting substrate and the structure is covered with a flexible upholstery material (5), for example, fabric, artificial or natural leather. The edges of the upholstery (5) are attached to the flat part (10) of the fasteners (6). The bent part (9) of the elements (6) is hooked to the protruding part (8) of the profile (2) along the perimeter of the frame from the inside (see Fig. 3). In this case, the fasteners (6) are held by the tension of the upholstery (6).
