Utility Model Implementation

The transformable furniture includes a fixed body of the lifting bed 1, a folding berth of the lifting bed 2, the sides of the sofa 3, and a retractable seat of the sofa 4. (Fig. 1) The design contains two independent transformation mechanisms. The first transformation mechanism 5 serves to transform the bed of a lifting bed, including two swivel joints and four gas shock absorbers (not shown). The second - 6 for the transformation of the sofa, which allows you to partially remove the seat of the sofa inside the body of the lifting bed, providing a comfortable height for the sofa seat (unfolded) and free access to the bed (in the folded position) (Fig. 2 and 3). The sides of the sofa 3 are rigidly connected to the side walls of the housing of the lifting bed 1. The back of the sofa 18 is rigidly fixed to the folding berth of the lifting bed 2.

The retractable sofa seat 4 and the side walls of the lifting bed 1 are connected by a transformation mechanism 6. The transforming mechanism of the sofa seat consists of two five-link mechanisms mounted on the sides of the lower part of the base of the seat, each of which is made in the form of the upper 8 and lower 11 horizontal bars, articulated from the front by a pivoting lever 9, and from the back, the upper lever of a L-shaped form 7 is pivotally connected to the lower pivoting lever 9. (Fig. 4) The lower horizontal bar 11 is made in the form of a rectangular hydrochloric pipe, the front part of which is rigidly welded U-shaped plate 12, which carries the plate 13 for mounting the sofa plug 19 performing the function of the sofa back 4 when the support bed is in the unfolded position. The upper horizontal rails are connected to the lower part of the base of the seat by means of fixing bars on the sides. The front pivot arm 10 pivotally connects the upper horizontal bar 8 and the lower horizontal bar 11. The front pivot arm 10 is made of a single plate. On the lower horizontal rungs front and rear mounted supports 14 with wheels. The front wheels 15 are designed to move the folded seat of the sofa on the floor, and the rear 16 to move along the guides inside the bed body, which facilitates access when folding the lifting bed. There are fixing belts for sleeping accessories, the berth is equipped with a folding supporting leg 17.

Enjoy a convertible bed with a sofa as follows.

A transformable bed with a sofa can be installed anywhere in the living room, including in a wall niche or as part of a bedroom set furniture set, where the wardrobe-bed should be rigidly fixed. Unfolding the transformable bed with a sofa begins by bringing the seat for the sofa to the folded position (Fig. 5) and moving the sofa seat inside the wardrobe, then pulling the folding bed with the handles onto it until the bed reaches a comfortable position, to move the supporting leg into a vertical position (Fig. 3), and then continue lowering the berth. Smooth lowering of the bed is ensured by gas shock absorbers with an estimated linear force of 400-2500 N (depending on the chosen bed size, mattress weight and facade weight) and the presence of a swivel joint. Next, you need to unfasten the fixing belts that hold (when the bed is upright) pillows and a blanket and the bed is ready for use. To bring the bed to its initial state, it is enough to perform all operations in the reverse order. At the same time, moving the bed to a vertical position is just as easy and smooth.

To unfold the sofa, first of all, it is necessary to roll out the lower part, the seat, which moves along special guides in the bed body, to the stop. The sliding part must be pulled up and towards itself, using the loop provided for this. The retractable sofa seat will lock in at the level required for seating. The assembly of the sofa is carried out in the reverse order: the sliding part is lowered (if it is pulled up and toward you) and rolled under the bed.

The design of the cabinet with a folding bed and a retractable seat provides compactness and allows its use in bedrooms, children's rooms, living rooms, etc.

Thus, the use of the proposed transformable furniture will create a new compact type of furniture, significantly improve performance by ensuring the reliability and quality of transformation.
