RU205669U1 - HIPLESS FRAME OF TOTCHAN-TRANSFORMER - Google Patents

Abstract

The utility model relates to furniture production and can be widely used for residential and office premises. Due to the design of the hinged frame of the transformer trestle bed, consisting of at least 4 blocks of lattices and at least two blocks of backs with the function of a bed, sofa, arena and chair, in which each blocks of volumetric lattices having free ends of profiles of various sizes , enter into each other, forming a single lattice, transformation in the bed of various aspect ratios into a playpen is achieved, without the use of hinges. In this case, the blocks of the backs have free profiles perpendicular to the plane of the backs, corresponding in size to the free profiles of the lattice blocks. Due to this, the backrests, also without hinges, can provide the functions of a sofa, armchair, arena fence.

Description

The utility model relates to furniture production and can be widely used for residential and office premises.

From patent No. 2 273 449 RU, a corner sofa is known that can be transformed into a bed. The sofa contains two bases on one side, rigidly connected with the armrests, which are supporting, and the other side with the third central corner also supporting the base. The soft elements of the back and seats have a tubular frame with elastic elements of the armor type. The frame of the larger seat is pivotally connected to the upper part of the frame of the soft backrest element by a pair of levers allowing the soft backrest element to roll over the seat, turning around the longitudinal axis to a horizontal position when transforming into a bed. The corner sofa bed has a modular design with the same attachment points for the bases and armrests, allowing you to swap the smaller and larger bases. A set of corner sofa beds can include two or more center corner bases of smaller or larger bases with backrests and seats. The disadvantage of this sofa is the presence of a hinge joint, which limits the resource of the sofa, increases the likelihood of breakage, and also limits the possibilities of transformation.

The objective of the claimed utility model is the manufacture of multifunctional furniture with an increased set of transformation options, reduced transformation time and increased resource.

The problem is solved due to the design of the hinged frame of the transformer trestle bed, consisting of at least 4 blocks of lattices and at least two blocks of backs with the function of a bed, sofa, arena and armchair. In the proposed frame, each block is a three-dimensional lattice containing at least two layers of tubular profiles. The frame consists of such blocks with the same number of layers of tubular profiles, entering each other by means of the fact that the blocks have free ends of the profiles at the edges and at the same time some of the blocks have internal dimensions of the profiles less than the external corresponding dimensions of the profiles of the other part of the blocks by an amount from 1 to 30 %, and the free ends of blocks of profiles of various sizes enter each other, forming a single lattice. In this case, the layers of the rectangle in the vertical plane are interconnected by upright stops made of metal pipes. As a result, when using the frame as a base, transformation is achieved in a bed of various aspect ratios, into a playpen, without the use of hinges. In this case, the backrest blocks have free profiles perpendicular to the backrest plane, corresponding in size to the free profiles of the lattice blocks. Due to this, the backrests, also without hinges, can provide the functions of a sofa, armchair, arena fence.

The technical result achieved during implementation consists in creating a simple structure that allows you to transform one object into another without the use of any additional mechanisms.
