On the basis of the above transformation mechanism, furniture is built for seating and lying, which has a stable state in extreme positions.

Description

The claimed technical solution relates to the furniture industry, in particular to transformable upholstered furniture.

In well-known versions of the design of furniture for sitting and lying, transformation mechanisms are used, which are the basis of this furniture and form the seat and berth, but at the same time, using the same transformation mechanisms, you can create various furniture products, for example: sofa beds, chair beds, also different from each other in appearance, design.

Known transformable upholstered furniture, patented in the Russian Federation as a patent for the invention - 7 A47C 17/13 RU (11) 2197881 (13) C2. The sofa bed according to this invention has a rigid frame, as well as a transformable part, consisting of a section for the head, section of the seat and section for the legs, interconnected. The rigid frame consists of a rear wall, sidewalls with guides for the side rollers of the transformation mechanism, a back attached to the rear wall and sidewalls from above, forming a cavity in the “sofa” position to accommodate the head section. The seat section is mounted on the metal frame of the seat section of the transformation mechanism, and the leg section is mounted on top of the articulated linkage "trapezoid" mounted on the metal frame of the section for the legs of the transformation mechanism. The foot section frame has a telescopic connection to the seat section frame. The guide rollers of the head section are attached to the head section. The head section and the seat section are connected by movable brackets. The transformable part is installed in the guides of the rigid frame.

The disadvantages of this solution are:

1. The inevitable cumbersome construction of the frame, especially the back, as it

section for the head is installed.

2. Inconvenience in the use and manufacture of a berth consisting of three sections connected in series - many components; which requires alignment of these sections in height and softness.

3. The need to manufacture guides of complex configuration in the side walls of the frame to ensure uniform movement of sections of the transformation mechanism without jerking.

4. The need to adjust the position of the sections inside the frame to prevent falling from the rails in the side walls of the frame.

The closest is the technical solution, patented as a utility model No.RU (11) 18890 (13) U1 7 A47C 17/13. The essence of this technical solution lies in the fact that the sofa bed consists of a frame with rails, on which the rear wall and sidewalls are mounted, which has three sections - “section for the head”, “section of the seat”, “section for the legs”. "Section seat" (soft seat element) is mounted on the metal frame of the "section seat"; the “foot section” (the soft element of the part of the berth “at the feet”) is mounted on top to the “trapezoid” articulated link mechanism mounted on the metal frame of the “foot section”; the “foot section” frame has a telescopic connection to the “seat section” frame. In the sofa bed there are: a back, permanently attached to the back wall and sides, forming a cavity for installing the "head section" in the "sofa" position; roller guides "sections for the head" mounted on the sidewalls; rollers mounted on the "section for the head", brackets connecting the "section for the head" and "section of the seat"; upper and lower guides for rollers made with flanges in the frame of the "section of the seat"; rollers with flanges mounted on the frame "section for the legs."

The main disadvantages of this solution are the same as those of the above solution.

This design is heavy, material-intensive, requiring precise manufacturing and high labor costs.

The technical result of the claimed design solution of the two-section telescopic transformation mechanism (hereinafter referred to as the transformation mechanism) is the creation of a stable, convenient to manufacture and use the base of furniture for sitting and lying, forming the seat and berth. The transformation mechanism consists of two telescopically connected to each other metal section frames: “seat sections” and “leg sections” of increased width, which, when folded, serve as a seat, and when unfolded, they form a berth of the required length.

The length of a berth created by two sections of a two-section telescopic transformation mechanism is defined as the total length of the frames: the frame of the "section of the seat" and the frame of the "section of the legs".

These results are achieved due to the fact that the transformation mechanism is made in the form of the structure shown in FIGS. 1 to 3, where FIG. 1 is the position of the parts of the transformation mechanism in the “bed” position, FIG. 2 is in the intermediate position, and FIG. 3 - in the "sofa" position, where: 1 - the frame "section of the seat", 2 - the frame of the "section for the legs", 3 - the guide "sections of the seat" 1, in which the rollers with flanges 4 are mounted, mounted on the frame of the "section for legs ”2.

Anti-skew rollers 5 are installed on the frame of the “section of the seat” 1 to prevent distortions during the movement of the transformation mechanism inside the frame of furniture for sitting and lying, and on the frame of the “section for the legs” 2 - the hinged-lever mechanism of the “trapezoid” 6.

The bearings of the two-section telescopic transformation mechanism are wheels 7. The frames of the “section of the seat” 1 and the “section of the legs” 2 are mounted on the wheels 7, and can freely move on the floor - roll forward and return to the original

position.

An example of a two-section telescopic transformation mechanism.

The frames for the “foot section” and “seat section” are made of a rectangular metal profile. The length of the frame of the "section of the seat" is 1060 mm, the height of the frame of the "section of the seat" is 250 mm, the length of the frame of the "section of the legs" is 910 mm. Two rollers are installed on the upper sides of the frame of the "section of the seat". The frame of the "section of the seat" is mounted on two pairs of wheels, and the frame of the "section of the legs" is mounted on one pair, which is mounted in the front part, and the rear support is a pair of rollers installed in the guides of the frame of the "section of the seat".

Close to the claimed technical solution of furniture for seating and lying is protected by utility model patent No.RU (11) 18890 (13) U1 7 A47C 17/13.

The disadvantage of this furniture is the bulkiness of the design, the complexity of manufacturing this furniture, the bulkiness of the back, the difficulty of aligning the sections in height in the "lying" position.

The technical result of the claimed design solution for furniture for sitting and lying, made on the basis of the above transformation mechanism, is to create a simpler to manufacture, easy to use, reliable, inexpensive product.

The transformation mechanism in the "sitting" position can roll into the frame to the rear wall, while part of it is located under the back. Stable position fixation is achieved by getting the front pair of wheels into two locks mounted on the front screed between the side walls of the frame, and the most convenient seat depth can be selected, which is possible due to the moving transformation mechanism and due to the presence of clamps with two positions.

In the “lying” position, the transformation mechanism is completely rolled out from under the back, while a comfortable berth is formed from two sections. Stable fixation of the position is achieved when the rear pair of wheels gets into the latches installed on the rear screed between the side walls of the frame. The location in the frame of the rear screed with latches determines the distance by which the transformation mechanism from the back can roll out and the size of the gap between the back and the rear edge of the bed.

The size of the berth can be further increased due to the flexible connection between the lower edge of the back and the upper edge of the berth attached to the upper edge of the seat section mounted on the transformation mechanism and to the back.

Moreover, the transformation mechanism does not affect the shape and height of the back. The backrest can be made: either in the form of an integral frame with a support under the pillows, and removable pillows, or in the form of an opening box, with a soft element fixed to the front lifting wall, under which a niche is formed. The presence of a niche in the back of furniture for sitting and lying makes this furniture highly functional, because this niche can be used as a place to store bedding, or as a closed shelf.

The inventive furniture for sitting and lying consists of a rigid frame and a transformation mechanism installed in it with a "seat section" and "leg section" attached to the top of its frames. The frame is formed by a back wall to which the side walls are rigidly attached. A back hanging over the seat is attached to the back wall, remote from the back wall, while in the “sofa” position a seat is formed, the depth of which corresponds to the ergonomic requirements established by GOST.

At the bottom between the side walls of the frame there are front and rear screeds with metal clips fixed to the floor in the form of plates with a section curved upwards, designed to fix the wheels of the transformation mechanism.

In the “sitting” position, the rear wheels of the “seat section” frame of the transformation mechanism are located at the rear wall of the frame, and the front wheels are in the latches of the front coupler. To change the seat depth, a latch with two positions is provided, while the entire transformation mechanism moves either forward or backward.

In the “lying” position, the rear wheels of the “seat section” frame of the transformation mechanism are installed in the rear coupler latches.

Between the lower edge of the back and the upper inner edge of the "seat section" mounted on the transformation mechanism, there is a flexible connection that can provide an additional increase in the berth. Flexible connection can be made detachable.

The back of the furniture for sitting and lying can be made either multilayer from the back attached to the back wall and removable pillows adjacent to it, or in the form of a box attached to the back wall, with a soft element fixed to the front lifting wall of the box, under which a niche is formed . A niche can be used as a place to store bedding, or as a closed shelf.

The inventive furniture for sitting and lying is presented in Fig. 4 - Fig. 6, Fig. 4 is a sectional view of "lying", Fig. 5 is an intermediate position; 6 is a position of "sitting" in the context, where:

1 - back wall;

2 - side walls of the frame;

3 - back;

4 - a niche between a sidewall and a back;

5 - rollers "antiperekos" installed in the transformation mechanism;

6 - flexible connection;

7 - wheels mounted on the transformation mechanism;

8 - a front coupler with a clamp;

9 - a back coupler with a clamp;

10 - articulated lever mechanism "trapezoid";

11 - "section seat";

12 - "section for the legs";

13 - frame "section of the seat";

14 - frame "section for the legs";

15 - connection of the parts of the flexible connection;

16 - transformation mechanism;

17 - rollers "sections for the legs" installed in the guides "section for the seat."

To transform furniture for sitting and lying, for example, a sofa bed, from the "sofa" position (see Fig. 6) to the "bed" position (see Fig. 4), the frame of the "foot section" 14, which is part of the transformation mechanism 10 by pulling on it.

The rollers 17 (see Figure 3-Figure 1), mounted on the frame of the "section for the legs" 2, are installed in the frame of the "section of the seat" 1, move along the guides of the "section of the seat" 3.

Then, together with the frame “section for the legs” 14 (see Fig. 6), the frame of the “section of the seat” 13 rolls out to the stop in the latch of the rear screed 9, while the rollers “anti-skew” 5 installed in the transformation mechanism move along the side walls of the frame 2.

Further (see Figure 5) the articulated lever mechanism "trapezoid" 10 changes its state - rises, while the "section for legs" 12, mounted on this mechanism "trapezoid" is on the same level as the "section of the seat" 13, and is its continuation, forming a berth.

A flexible connection 6 between the backrest 3 and the "seat section" 11 is made in the form of a fabric. So that the sofa bed can be disassembled into modules during transportation, this

the flexible connection 6 can be made connected either by means of hooks or a zipper, or by connecting the joints of the joints with a Velcro contact tape, or by any other known method, where position 15 is the connection of the parts of the flexible connection. The sleeping place is ready.

When transforming a sofa bed from the "bed" to the "sofa" position, it is necessary to perform the manipulations in the reverse order.

1. - Lower the "section for the legs" 12, mounted on the articulated lever mechanism "trapezoid" 10 of the transformation mechanism 16.

2. - Roll the frame of the "section for the legs" 14 into the frame of the "section of the seat" 13.

3. - Next, roll the frame "section of the seat" 13 until it stops, between the side walls of the frame 2 so that the front wheels mounted on the frame of the "section of the seat" 13, went into the selected position of the clamps of the front coupler.

An example of the execution of furniture for sitting and lying.

Furniture for sitting and lying is made in the form of a frame with a low back - a support, in which there is a niche with shelves, removable pillows installed on the "section for the seat", mounted on the frame of the "section for the seat" of the transformation mechanism.

The transformation mechanism is made of two telescopically connected sections - the "section of the seat" and "section for the legs", which when folded serve as a seat, part of which is located under the back. When forming a berth, the seat rolls out from under the back, the "foot section" rolls out from under the "section of the seat" and rises to the level of "seat section".

The transformation mechanism moves freely inside the side walls of the frame. The position of the transformation mechanism relative to the frame is adjusted by adjusting the position of the anti-skew rollers installed in the transformation mechanism. This sofa design allows for a length of "seat section" of 1060 mm,

and a depth of 1100 mm create a berth with a length of 1970 mm.

Due to the use of the connection between the back and the "seat section" made of fabric, it is possible to increase the length of the berth by, for example, another 200 mm.
