The frames of the base, soft elements and backs are made tubular.

The prototype is a piece of furniture for sitting and lying with a transformation mechanism (RU, 92312, А47С 17/13, 03/20/2010), comprising a body, a back, a sliding part with a frame and a pillow, a transformation mechanism made on the basis of articulated joints that provide movement the sliding part and raising the cushion to form a place for lying, characterized in that the transformation mechanism is made of a lifting-and-sliding, containing a rolling-out frame on which two lifting mechanisms are mounted, a rolling-out mechanism made in the form of a set articulated GOVERNMENTAL sliders and flat plates provided with regulation nodes stretching, and further comprises a strut, one of which is fixedly secured to the rear inner wall of the piece of furniture and the other - on the withdrawable frame.

Disadvantages - the need for a gap between the sofa and the wall for folding, the felt joints between the back and the seat when forming a berth.

The purpose of the invention is to increase the functionality of a corner sofa bed and its ease of use.

The task to which the utility model is directed is to eliminate these drawbacks, i.e. creation of a corner sofa bed with increased functionality, more convenient to use and with simpler details, maintainable.

The problem is solved in that in the known mechanism for transforming an angular sofa bed, including a sofa base, a sliding base connected by guides on the sofa base and interacting with these guides installed on the base of the retractable pull-out wheels, the side base made of metal pipes and equipped with supporting parts, a linen box, as a limiter for the base of the slide-out between the tubular guides, a plate with stops on which the plates are mounted stmassovye laths and linen box with lateral base mounted thereon is attached to the base of the couch by means of wedge hooks.

The maximum permissible distributed static load on an unfolded berth is 200 kg.

The transformation mechanism is a three-dimensional structure and consists of the following main parts:

1. The base of the sofa.

2. The base is retractable.

3. The base is lateral.

The base of the sofa consists of a base frame and a base frame. The base frame is a welded structure, which is made of a profile pipe 20x20 mm. The base frame consists of two left and right sidewalls, welded together by a jumper. Two parallel sidewall pipes act as guides for the rollers of the base of the retractable. The rear legs of the base frame simultaneously serve as a limiter of the extreme rear position for the base of the retractable. The limiter for the base of the retractable in the extreme forward position are plates welded between the pipes, which form the guides. Stops are welded to the plates, which exclude horizontal displacement and backlash of the sliding base when moving it.

To reduce friction and eliminate damage to the paintwork, a plastic overlay is installed on the stops, which acts as a sliding bearing. The base frame performs the supporting function for the entire sofa. On the left and right sides of the base frame, wedge hooks are installed to ensure the attachment of a linen box or the installation of an armrest. The linen box can be attached to the base of the sofa both on the left and on the right, as well as the armrest can be installed both on the right and on the left. The base frame is fastened to the base frame using a bolt connection, the frame of which is made of a profile pipe 30 × 30 mm onto which bent glued elastic elements (latoflexes) are installed through intermediate parts (lato-holders). The base of the sofa, through rolling wheels mounted on a sliding base, interacts with it. The sliding base consists of a base frame, a base frame and two lifting mechanisms (left and right). On the base frame, using a bolted connection, two lifting mechanisms are installed. The base frame is attached to the lifting mechanisms, also by means of a bolted connection. In front of the base of the drawer, two wheel bearings are installed, by means of which the drawer has contact with the floor. The back of the base of the drawer rests on the sidewalls (left and right) of the base of the sofa by means of two withdrawable wheels. The base frame is a welded structure, which is made of a profile pipe 20 × 20 mm. Lifting mechanisms with swivel joints are designed to change the height of the base frame when the transformation mechanism is moved from the “sofa” position to the “bed” position and vice versa.

Lifting mechanisms are made of strip and angular profile. The frame of the base frame is made of a profile pipe 30 × 30 mm, on which bent glued elastic elements (latoflexes) are installed through intermediate parts (lato-holders). The base sliding with two pull-out wheels interacts with the guides of the base of the sofa and has the ability to move in the horizontal plane when the transformation mechanism is switched from the “sofa” position to the “bed” position and vice versa.

The lateral base is intended for installation on a linen box. It consists of a base frame and two lifting mechanisms (left and right). The lifting mechanisms are attached to the side walls of the linen box and provide lifting of the base frame, allowing access to the inside of the box. The frame of the base frame is made of a profile pipe 30 × 30 mm onto which bent glued elastic elements (latoflexes) are installed through intermediate parts (lato-holders). The base frame is attached to the lifting mechanisms by means of a bolted connection. A linen box, with a lateral base mounted on it, is attached to the base of the sofa with wedge hooks.

A wedge hook - a bayonet, consists of elements that are inserted into each other, serves to connect furniture parts and hold them pressed to each other. The hooks are used so that they are not visible on the furniture. The hook parts to the linen box and the armrest are mounted on screws or bolts, and to the structural elements of the transformation mechanism by welding, which ensures their snug fit to the furniture details. Hooks are made of galvanized steel of sufficient thickness. The advantage of this fastening is simplicity, reliability, maintainability, easy replacement, as well as excellent load-bearing ability. Plastic plugs are installed on all open ends of the pipes of the transformation mechanism. All metal structural parts are painted with RAL7035 powder paint.

Thus, as a result of the implementation of the utility model, the following advantages are achieved:

1) simplification of the design, increasing reliability and improving the operational characteristics of the angular sofa bed by eliminating spherical bearings and introducing roller and wheel bearings giving linear contact, rather than point contact, by using structural elements of the base of the sofa bed as guides for withdrawable rollers base retractable;

2) comfort and ease of use due to the use of a drawer for linen in the sofa bed;

3) lightness and strength of the structure due to the use of a profile pipe in the manufacture of elements that make up the transformation mechanism.

Regardless of the type of furniture, the process of transformation from a “sofa” to a “bed” occurs the same way. It is performed in two simple steps.

1. We take a special loop or handle and fully roll out the base retractable;

2. Raise the base frame up and pull it towards you, as a result of which the base frame becomes one level with the seat, forming a berth. To add structure, it is enough to do all the operations in the reverse order. First you need to lower the base frame, then roll the base retractable into place. If the mechanism is operational, all manipulations are carried out without much difficulty. Such a sofa does not need to be moved away from the wall.

Thus, the implementation of the utility model solves all the problems posed by the authors.
