Abstract

Folding sofa bed, consisting of a vertical wall box, a bed base with a support, a folding headboard, a mechanism for raising the bed base, a sofa bed, a mechanism for lowering a sofa bed, a sofa bed stop, characterized in that the bed base support is made in the form of a flip frame designs with a central emphasis.

Description

The utility model relates to light industry, in particular to transformable furniture, which can be converted from a sofa into a bed by lowering the folding base of the bed and can be used in rooms with a limited area.

Known folding bed (RU 50783, A47C 17/38, 01/27/2006), containing elements of cabinet furniture: a vertical wall housing, a mattress frame made of longitudinal and transverse elements, equipped with half shafts, a supporting frame in the form of a U-shaped rack, at the ends the branches of which the pins are rigidly fixed, in the pockets of which there are bearings covering the axles of the carcass, in the base of the branches are hard limiters that interact with the frame frame stops by means of adjusting elements, the bed transformation mechanism, bzhenny straps attached to the frame of the counterweight with the possibility of relative movement, the branches U-shaped strut on both sides of the frame is rigidly fastened harnesses stops, the support legs are connected to the frame by means of bolts and bearings.

The disadvantages of the known beds are the lack of a sofa seat in the folded position of the bed.

Closest to the claimed technical solution is the sofa bed selected as a prototype

(http://www.yapokupayu.ru/system/images/product/006/524/666_zoom.jpg, http://www.yapokupayu.ru/system/images/product/006/524/664_zoom.jpg, 1_zoom .jpg), consisting of a vertical wall box, a bed base with folding legs, a folding headboard, a bed base lifting mechanism, a sofa bed, a sofa bed lowering mechanism, a sofa bed rest.

A disadvantage of the known sofa bed is the low stiffness of the foot of the bed base and the associated restrictions on the maximum allowable weight maintained by the sofa bed.

The task of developing a utility model is to create the design of a folding sofa bed, providing an increase in the maximum allowable weight withstand a folding sofa bed.

The specified technical result is achieved in that the folding bed-sofa consists of a vertical wall box, a bed base with a support, a folding headboard, a mechanism for raising the bed base, a sofa bed, a mechanism for lowering the base of the sofa, an emphasis on the bed base, and the bed base support is made in in the form of a cross over frame design with a central emphasis.

In FIG. 1 shows a view of a folding sofa bed in the “bed” position. In FIG. 2 shows a view of a folding sofa bed in a position in which the bed base support is thrown to the folding position. In FIG. 3 shows a view of a sofa bed in an intermediate position. In FIG. 4 shows a view of the sofa bed in the "sofa" position.

The folding sofa bed (Fig. 1, Fig. 2, Fig. 3, Fig. 4) consists of a vertical wall box 1, the base of the bed 2 with a flip support of the frame structure 3 with a central emphasis 4, a folding back of the head of the bed 5, a mechanism lifting the base of the bed consisting of parts 6 fixed on both sides of the wall box 1 and pivotally connected parts 7 fixed on both sides of the base of the bed 2, gas springs 8 installed between parts 6 and 7, the base of the sofa 9, lowering mechanisms of the base of the sofa 10 connecting with of both sides of part 7 and the base of the sofa 9, folding support base of the sofa 11.

A folding sofa bed is transferred from the "bed" position (Fig. 1) to the "sofa" position (Fig. 4) as follows.

Raising the foot of the bed, turn the base of the bed 2 and the associated parts 7 relative to the hinge attachment to the parts 6, while the gas springs 8 installed between the parts 6 and 7, expanding, facilitate the lifting of the base of the bed 2. Swing the flip support frame structure 3 (Fig .2) and continue to rise the foot of the bed, turning the base of the bed 2 to a vertical position, while the lowering mechanisms of the base of the sofa 10 raise the base of the sofa 9, folding the folding support of the base of the sofa 11. In the vertical position of the base bed 2 is maintained pressurized gas spring 8 mounted between the portions 6 and 7.

A folding sofa bed is transferred from the "sofa" position (Fig. 4) to the "bed" position (Fig. 1) as follows.

Moving the foot on itself and down, turn the base of the bed 2 and the associated parts 7 relative to the hinged attachment to the parts 6, while the gas springs 8 installed between the parts 6 and 7, compressing, facilitate lowering the base of the bed 2. Tilt the frame support frame 3, while the central emphasis 4, resting against the middle part of the foot of the base of the bed 2, provides additional support in the center of the foot. The footing continues to move downward, turning the base of the bed 2 to a horizontal position, while the lowering mechanisms of the base of the sofa 10 lower the base of the sofa 9, folding the folding support of the base of the sofa 11, and the base of the bed 2 rests on the flip support of the frame structure 3 with a central focus 4.

As a result of the implementation of this technical solution, by supporting the bed base not only on the sides, but also in the center, an increase in the stiffness of the bed support at the foot of the bed is achieved, and an increase in the maximum allowable weight withstand the folding sofa bed.

Claims (1)

Folding sofa bed, consisting of a vertical wall box, a bed base with a support, a folding headboard, a mechanism for raising the bed base, a sofa bed, a mechanism for lowering a sofa bed, a sofa bed stop, characterized in that the bed base support is made in the form of a flip frame designs with a central emphasis.
