Description

The utility model relates to light industry, in particular to transformable furniture, which can be transformed from a vertical position to a horizontal position "bed" by lowering the folding base of the bed and can be used in rooms with a limited area.

Known folding bed (RU 50783, А47С 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 bases of the branches are hard limiters interacting with the frame frame stops by means of adjusting elements, the bed transformation mechanism, with abzhenny 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 use of the counterweight and the associated design complexity.

Known folding bed (RU 2284138, А47С 17/38, 09/27/2006), consisting of a rotary frame, two fixed supports and a rotary mechanism containing two gas compression springs mounted on the sides of the rotary bed frame. In the folding bed, the first fastener for fixing one end of the gas spring of the rotary mechanism is mounted on the rotary frame at a point offset from the head of the bed, greater than the offset of the bearings, and the second fastener for securing the second end of the gas spring is mounted on the flange of the rotary mechanism below the horizontal line passing through the axis of the bearing at a distance from the head greater than the displacement of the bearing. The distance between the axes of the fasteners in the vertical position of the bed is not more than the length of the gas spring in the free state.

A disadvantage of the known folding bed is the lack of rigid fixation of the folding bed in an upright position, and the associated possibility of spontaneous folding of the folding bed when children are pampered or gas springs fail.

Closest to the claimed technical solution is the bed selected as a prototype (CN 202842996 U, А47С 17/52. 04/06/2011), consisting of a vertical box, a bed base with a support, a mechanism for lifting the bed base and a locking mechanism.

A disadvantage of the known bed is the difficulty of fixing the folding bed in an upright position, the need to use two hands for this, one to hold the bed base, the other to actuate the locking mechanism.

The task of developing a utility model is to create a design for a folding bed, providing ease of fixation of the folding bed in a vertical position, and its release.

The specified technical result is achieved in that in a folding bed, consisting of a vertical wall box, a bed base with a support, a mechanism for lifting the bed base, a locking mechanism, the locking mechanism is made in the form of a latch lock consisting of a holder box, a rod placed on both sides of the wall box , a coil spring, a leaf spring, as well as a hook placed on both sides of the base of the bed with a head and a sleeve.

In FIG. 1 shows a folding bed in the unfolded position. In FIG. 2 shows a view of a folding bed in a position preceding a snap. In FIG. 3 shows the latch-lock mechanism in a fixed position. In FIG. 4 presents the mechanism of the lock-latch when pressed on the base of the bed. In FIG. 5 shows the latch-lock mechanism at the time of separation.

The folding bed (Fig. 1) consists of a vertical wall box 1, the base of the bed 2 with a support 3, a mechanism for lifting the base of the bed, consisting of parts 4 fixed on both sides of the wall box 1 and pivotally connected parts 5 fixed on both sides of the base beds 2, gas springs 6, installed between parts 4 and 5, a latch lock, consisting of a holder 7 located on both sides of the wall box 1, a rod 8, a coil spring 9, a leaf spring 10, placed on both sides of the base of the bed 2 of the hook with Goal Application Serial 11 and the sleeve 12.

A folding bed is moved from the "bed" position (Fig. 1) to the upright position as follows.

Raising the foot of the bed, turn the base of the bed 2 and the associated parts 5 relative to the hinge attachment to the parts 4, while the gas springs 6 installed between the parts 4 and 5, expanding, facilitate the lifting of the base of the bed 2. Throw the support 3 and continue to lift the foot, turning the base of the bed 2 to a vertical position (Fig. 2), while the hooks with the head 11 located on both sides of the base of the bed 2, press the rod 8 into the holder 7, compressing the coil spring 9 and spreading the tab spring 10. Petal spring 10 shifts the sleeve 12 and engages with the head 11 of the hook (Fig. 3), fixing, thus, the base of the bed 2 in an upright position.

A folding bed is moved from an upright position to a “bed” position as follows.

While pushing at the foot, the bases of the bed 2 are slightly sunk into the wall box 1, while the hooks with the head 11 located on both sides of the base of the bed 2 press the rod 8 into the holder 7 to the end, compressing the coil spring 9, while the sleeve 12 further extends the tab spring 10 (Fig. 4). Stop pressing on the foot of the base of the bed 2, while the spiral spring 9, unclenching, acts on the rod 8, squeezing out the hooks with the head 11 placed on both sides of the base of the bed 2 from the petal spring 10, while the petal spring 10 moves the sleeve 12 to the head 11 of the hook and then, sliding on the sleeve 12, does not engage with the head 11 of the hook (Fig. 5), providing the opening of the lock-latch. Moving the foot on itself and down, turn the base of the bed 2 and the associated parts 5 relative to the hinged attachment to the parts 4, while the gas springs 6 installed between parts 4 and 5, compressing, facilitate lowering the base of the bed 2. Throw the rocker support 3, continue to move the foot of the bottom, turning the base of the bed 2 to a horizontal position in the "bed" position.

As a result of the implementation of this technical solution, the ease of fixing the folding bed in a vertical position and its release, as well as the possibility of carrying out these operations with one hand, is ensured.
