Description

Field of technology to which the utility model relates

The utility model relates to the field of furniture production and is intended for use in the frames of a transformable sofa bed.

State of the art

Among the large number of designs of folding upholstered furniture such as chair-beds and sofa beds, for example, transformable furniture for sitting and lying down is known (RU 2443381C1, IPC A47C17/13, publ. 02.27.2012, [1]). As in the claimed technical solution, analogue [1] includes a first section and a second section adjacent to the first. When transforming furniture for sitting and lying down, one of the sections is movable relative to the other and is supported on the floor surface by means of support units located on the sides of the section base. Each of the support units is equipped with a wheel and contains a spatial body and a connection unit between the spatial body and the base of the section, allowing rotation. On the side opposite to the base of the section, the spatial body is equipped with a pair of wheels.

The mechanism for transforming furniture is also known (RU157675U1, IPC A47C 17/13, published 12/10/2015, [2]). As in the claimed technical solution, analogue [2] consists of roll-out carriages containing a frame mounted on racks and placed with the ability to interact with each other in such a way that the frame of each subsequent carriage is made with the ability to move along the guide sides of the frame of the previous carriage. What is new is that the carriages are equipped with bases for sitting/lying, one end of which is fixed in a holder having a U-shaped section with protruding ends of an L-shaped profile, and on the transverse side of the carriage frame in contact with the holder, corresponding L-shaped grooves are made In addition, each base is installed with the ability to slide along the surface of the previous/successive base when the carriage moves. This design simplifies the design due to a simple mechanism for transforming furniture and makes assembly and operation easier.

A common disadvantage of the designs of analogues [1] and [2] is the large number of manipulations associated with the transformation of furniture, the fragility and unreliability of the structure during operation and the complexity of converting furniture from one type to another.

The prototype for the proposed utility model is the frame of a transformable sofa bed (RU221714, patent holder Anatoly Viktorovich Zhivaev, MPK A47C 17/13, published 11/21/2023, [3]), containing a roll-out base, which contains guide bases, the first and second crossbars of the base , base posts welded together. In this case, the guide bases (1) are equipped with first and second wheels (3, 4) for rolling out the base.

The disadvantage of this device [3] is the insufficient number of design transformations depending on the wishes of the user and the free space of the room.

The technical problem being solved is the need to improve the mechanism for transforming from a seat to a lying one, to increase and expand the performance qualities of folding furniture while maintaining simplicity of design and operation.

contains a carriage (25) with a transformation mechanism (23), which is installed inside the seat (17) with the ability to move the second mushroom wheels (22) along the second crossbars (10) of the seat (17), while the carriage (25) is fixed to the front part second brackets with wheels (24), while the transformation mechanism (23) is fixed to the third crossbars (21) of the carriage (25);

on the base (7) a frame-hood (28) is fixed with the possibility of folding, which is the frame of the headrest.

In particular cases, it is permissible to implement a technical solution as follows.

The base (7) is preferably made motionless.

An ear (6) is movably fixed in the upper part of each rear first post (4) of the base (7).

The seat (17) contains rear second pillars (11), which are connected by upper and lower second pipes (8). Moreover, the front second pillars (11) are connected by one upper second pipe (8). In this case, under the upper rear second pipe (8) on the second racks (11) a stop pipe (12) is fixed. In addition, transverse stiffeners (9) are fixed between the upper second pipes (8).

On the back of the seat (17) on the second pipes (8) there is a vertical second stop (13) with a wheel (14).

The horizontal third crossbars (21) are connected to each other by a longitudinal arc (18), on which the plates (20) are fixed.

The set of essential features of the proposed utility model is unknown from the prior art for devices of similar purposes, which allows us to conclude that it meets the “novelty” criterion for the utility model.

The frame of the transformable sofa bed was carried out by a specialist in practice and, when implemented, ensures the implementation of the stated purpose.
