Description

The utility model relates to the field of furniture products, in particular to transformable chairs, more precisely chaise lounges, with a changeable configuration of the body support and designed for sitting or resting a reclining one person.

There are (known) various devices for this purpose. A device is known for the adjustable inclination of the back and seat of a chair (patent FR 8906876 IPC A47C 1/032, 1989). The chair in accordance with this invention contains a backrest and a seat that are pivotally connected to each other and the supporting elements of this chair. The armrests of the chair are pivotally connected to the back and are connected to the legs by means of gear racks. The angle adjustment of the seat and backrest also produce gear racks. A significant disadvantage of this technical solution is the low comfort when using it.

The closest set of essential features to the claimed utility model and adopted as a prototype is a deck chair (patent for utility model UA 20694 IPC A47C 1/1, 2007). The utility model relates to furniture products, in particular lightweight folding adjustable chairs, which are comfortable to sit or relax reclining. The deck chair contains racks with upper and lower crossbars, quadrangular large and small frames, cross-connected by separate coaxial joints, a rod for attaching a panel or massager and a device for fixing the angle between the frames, made on a small frame in its rear lower part with the possibility of fixing with a jumper П- armrests, the ends of which are hinged through supports to the uprights in their upper part. In addition, the presence of hard cross members within the deck chair provides the user with the opportunity to sit or rest reclining, which, combined with the ability to quickly change the elements of the cloth or massager, complements the possibilities of its use.

Analysis of the technical characteristics of the prototype showed that, along with the advantages, there are significant disadvantages: low comfort during its operation, as well as low aesthetic quality (design).

The claimed utility model is based on the technical task of simplifying the design, increasing operating comfort and ease of fixing the positions of the back angle when transforming the chair into a chaise lounge, and improving aesthetic properties (design).

The stated technical problem is achieved by the fact that the claimed utility model contains sidewalls of bent elements, which are a rack with a support and armrest, made of one bent element (part). The sidewalls are interconnected by the front and lower crossbars (drawbars). Also contains quadrangular large and small frames. A large frame forms the back of the chair and contains a hard jumper. The small frame forms a seat with lower toothed devices for fixing the angle of inclination of the back. The frames are interconnected by coaxial joints on a common jumper. Soft ribbons or spring snakes are tensioned and fixed inside the large frame along its entire length, providing support to the user's back. In addition, the back of the chair may contain a massager in the form of a roller on a transverse tape mounted on the frame. On the small frame that forms the seat, flat wire springs are fixed, forming a spring mesh. A large frame is connected to the sidewalls with coaxial joints.

The seat, backrest and armrests are soft coated for comfort. The transformation of the chair into a chaise lounge provides the presence of a swivel in the back and the ability to fix the position of the chair with lower gear devices behind the front jumper when pushing the seat forward

The essence of the utility model is illustrated by drawings, which depict:

in Fig 1 - frame, General view;

in Fig 2 - frame, side view;

in Fig 3 - frame, rear view;

in FIG. 4 declared chair (frame with soft coating). General form.

as shown in FIG. 1, FIG. 2, FIG. 3, the frame of the chair contains sidewalls 1, which are racks with a support and armrest, made of one bent element (part). The sidewalls are interconnected by the front 2 and lower 3 crossbars (drawbars). A large frame 4 with a rigid jumper 8 forms the back of the chair, and a small frame 5 forms a seat with lower gears 6 mounted to fix the angle of the backrest and seat. The frames 4 and 5 are interconnected by short sides by coaxial joints 9 on a common rigid jumper 7. Inside the large frame 4, soft ribbons or spring snakes 12 are tensioned and fixed to support the back of the user. In addition, the back of the chair may contain a massager 11 in the form of a roller on a transverse tape mounted on a large frame 4. On a small frame 5 that forms the seat, flat tension springs 10 made of wire are installed and fixed, forming a spring mesh to absorb the seat support. A large frame 4 is connected to the sidewalls 1 with coaxial joints 13.

For practical use of the claimed frame as a chair - a deck chair, it is necessary to install a soft cover 14 on the spring mesh of the seat, back and armrests, as shown in FIG. four

The claimed utility model works this way.

For comfortable work or rest reclining there is a need to change the angle of the backrest to the seat. The chair is transferred from the sitting position to the reclining position (deck chair) by moving (pushing forward) the small frame 5 (seat), for which it is necessary to raise the front of the frame 5 and disengage the gear device 6 from the mesh (fixation) with the front cross member 2 Pull the frame 5 forward and, after obtaining the required angle of inclination of the backrest to the seat, lower it by fixing the gearing devices 6 to the front cross member 2. The chair is returned to its original position in the reverse order of the above.

As a result of the implementation of the claimed utility model, we obtain a comfortable chair, adapted both for sitting and relaxing reclining with a simple and convenient adjustment of the angle of inclination of the back to the seat, aesthetically attractive.
