Description

The utility model relates to the production of furniture, namely the production of side walls of sofas and armchairs [A47C 17/00, A47C 7/54].

The prior art known SIDE WALL FURNITURE [RU 151836 (U1), publ. 04/20/2015], containing a folding table with a mechanism for fixing in a horizontal position, a frame is placed inside the hollow side wall, a folding table with a mechanism for fixing in a horizontal position is attached to the upper part of the inner side of the frame, characterized in that the outer side of the frame communicates with the inner side of the side walls with a pair of guides, full roll-out guides or roller guides are used as guides.

The disadvantage of this analog is the low reliability of the side wall, due to the fact that in the unfolded position of the sofa, the side wall is not fixed to the bed of the sofa.

Known from the prior art SIDE FOR UPHOLSTERED FURNITURE [RU 201452 (U1), publ. 12/15/2020], containing a frame with a pocket equipped with an opening cover-armrest, the first table located on one side of the pocket, characterized in that the frame consists of a U-shaped base, the upper part and the inner side wall, fastened together, the sidewall is additionally contains a second table, located on the other side of the pocket, and a drawer, made in front of the upper part of the frame, while the depth of the drawer is equal to the length of the table above it, and on the outer side, the sidewall frame has an open side niche.

The disadvantage of analogue is that when using the sofa in the unfolded position, the sidewall of upholstered furniture cannot provide ease of use for the user, due to the fact that the length of the sidewall of the sofa is not located along the entire length of the end part of the bed, which leads to small options for the location of the pillow and the user on sleeping place.

The closest in technical essence is SOFA BED [RU 75284, publ. 08/10/2008], containing a rear wall, a retaining board, an anatomical double-sided backrest hinged to the sidewalls, a retractable seat with an opening lid and a drawer on support wheels, a transformation mechanism that includes a pair of rods hinged at one end to the anatomical backrest, and the other ends - with a retractable seat, characterized in that the rear wall and the retaining board with the sidewalls are connected detachably, a headrest is hinged to the rear wall, resting on the back in the deployed position, the sidewalls are equipped with tables and pockets with opening armrest covers, the cover of the retractable seat opens to the side back and is fixed at a given angle using the locking mechanism.

The main technical problem of the prototype is its limited functionality, due to the inability to change the location of the sidewall along the entire length of the bed and use it as a pillow stop along the entire width of the sofa.

The purpose of the utility model is to improve the design of sofas.

The technical result of the utility model is the expansion of the functionality of the sofa, namely, the provision of the possibility of placing the pillow stop both on a part of the width of the sofa, and across its entire width.

The claimed technical result is achieved due to the fact that the sofa with an emphasis for the pillow consists of a back wall, left and right sidewalls and a berth, interconnected by fastening elements, characterized in that the sidewall is made in the form of two parts, while the first part of the sidewall is hollow and rigidly connected to the rear wall and the sleeping place, on the inner walls of the first part of the sidewall there is an anti-friction material, which is configured to interact with the upholstery material placed on the side walls, the bottom and the upper part of the pillow support, the front edge of the sleeping place protrudes beyond the front the outer side of the first part of the sidewall, the second part of the sidewall is an emphasis for the pillow and is connected to the protruding part of the bed by means of a vertical interlocking connection, the second part of the sidewall is made with the possibility of being placed in the cavity of the first part of the sidewall, while the longitudinal and transverse dimensions of the second part of the sidewall are smaller longitudinal and transverse dimensions of the first part of the sidewall, and a handle is placed on the side outer wall of the second part of the sidewall.

Implementation of the utility model.

A sofa with an emphasis for a pillow (see Fig.1) consists of a rear wall 1, left and right sidewalls 2 and a bed 3, interconnected by fasteners (not shown in the figures). The sidewalls of 2 sofas are made in two parts. The first part of the sidewall 2 is hollow and rigidly connected to the rear wall and the sleeper 3 by means of fasteners, which can be bolted elements, while the front edge of the sleeper 3 protrudes beyond the front outer side of the first part of the sidewall 2. On the inner walls of the first part sidewall 2 is anti-friction material (not shown in the figures).

The second part of the side frame 2 is a cushion stop 4 and is connected to the protruding part of the bed 3 by means of a sofa connector 5, while the longitudinal and transverse dimensions of the pillow stop 4 are smaller than the longitudinal and transverse dimensions of the first part of the side frame 2.

Cushion stop 4 (see Figure 2, 3) is formed by side walls 6, bottom 7 and upper part 8, made, for example, of chipboard material and fastened together by means of fasteners (not shown in the figures). The bottom 7 of the cushion support 4 contains a spring leg-support 9, which is movable from the inner volume of the cushion support housing 4 to the outer space and back.

On the side wall 6, connected to the bed, there is a sofa connector 5, made in the form of a vertical interlocking connection, while the second part of the sofa connector 5 (see Fig.4) is placed on the outer side of the sofa bed 3. The sofa connector 5 is placed on the side wall 6 and on the berth of the sofa 3 with the possibility of vertical connection of the sofa stop for pillow 4 with the side of the berth of the sofa 3.

On the bottom 7, the side walls 6 and the upper part 8 of the cushion support 4 there is an upholstery material.

A handle 10 is placed on the side outer wall of the cushion support 4.

A sofa with an emphasis for a pillow is used as follows.

The bed 3 of the sofa is unfolded, then the pillow stop 4 is pulled out of the side wall by the handle 10 located on the outer end side wall, by sliding the upholstery material located on the pillow stop 4 along the anti-friction material located on the inner walls of the sidewall 2. 2 sofas along the bed 3 sofas, then press the pillow stop 4 to the side of the bed 3, and engage the pillow stop 4 with the side of the bed 3 using the sofa connector 5 by vertically moving the pillow stop 4 from top to bottom, while In this case, the support for the pillow 4 rests with the leg-support 9 on the floor, forming an additional point of support.

The removal of the stop for the pillow 4 and moving into the inner space of the sidewall 2 is carried out in the reverse order.

The technical result - the expansion of the functionality of the sofa, namely the provision of the possibility of locating the pillow stop both on part of the width of the sofa, and across its entire width, is achieved due to the fact that in the connected position of the sofa stop for the pillow with the side of the sofa berth 3 is formed additional support area used to support the pillow located at the edge of the bed 3.

An example of achieving a technical result.

When using a sofa for sleeping without a support for pillow 4, the user is forced to position the pillow in such a way that the pillow rests against the side of the sofa 2, which leads to a decrease in the usable area of the bed 3 of the sofa for its intended purpose. When using the pillow stop 4, the user did not change the spatial position of the body during sleep, while the pillow remained fixed on the edge of the bed 3 of the sofa.

In 2022, the applicant produced a prototype of the claimed technical solution, the trial operation of which confirmed the claimed technical result - expanding the functionality of the sofa, namely, ensuring the possibility of placing the cushion stop both on part of the width of the sofa and across its entire width.

The proposed technical solution is industrially applicable, since it can be manufactured industrially, workable, feasible and reproducible, therefore, it meets the condition of patentability "industrial applicability". At the same time, the utility model can be implemented in industrial production using simple equipment and modern materials.
