The disadvantage of this device is the relatively narrow functionality, due to the possibility of using it only in relation to the sleeping area of the sofa bed.

There is also known a device - a means of transformation for upholstered furniture [RU 126580, U1, A47C 17/13, 04/10/2013] containing a transformation mechanism, a retractable frame with rolling bearings located in its front part and an additional soft element mounted on it, and containing a lever the lifting mechanism, and located in its front part of the drawer, rigidly connected to the housing of the sliding frame, longitudinal beams fastened by transverse elements, moreover, the transformation mechanism contains sidewalls, fastened together in a transverse direction and, longitudinal guides, rigidly interconnected by transverse elements, and is equipped with two side rollers with a flange inserted in the longitudinal guides and two stops restricting the movement of the said rollers with flanges, while the transformation mechanism is made of metal tubular frames, and the said mechanism the transformation is made of three supporting tubular elements, including the said retractable frame, the base frame and the support rotary frame, and the said retractable frame of the mechanism tr The information is located inside the base frame and is made of an integral welded structure containing upper longitudinal beams fastened by welding with upper transverse elements, lower longitudinal beams fastened by welding with lower transverse elements, middle longitudinal beams located above and below in the central part of the sliding frame, front , rear and central racks, connecting the upper and lower longitudinal beams and transverse elements by welding, and equipped with lateral beams fixed to the welded metal frame and the central partition made in the form of a Central wall, which are located between the aforementioned longitudinal beams and racks, and equipped with a bottom, and the said walls and the bottom of the sliding frame are made mainly of decorative panels made of durable material, while the said lever mechanism is made in the form of spring lever lifting mechanism equipped with fluoroplastic washers and mounted on the said side walls of the sliding frame, and said drawer is fixed to the front of the sliding about the frame through two plates, mainly with furniture bolts, and the retractable frame is equipped with a welded metal frame made with the possibility of installing said additional soft element on it, while the welded metal frame is fixed to the bracket located in the upper part of the said spring-lever lifting mechanism, and the aforementioned the rolling bearings located in front of the sliding frame are made in the form of rubberized wheels fixed in a metal cage and are fixed ry located under the rubber wheels in the front of the base frame, and the said latches are made with the possibility of protection against spontaneous rolling of the rubber wheels in the "bed" position, while the said base frame is made in the form of a solid welded structure containing lower longitudinal beams fastened by welding with lower transverse elements, the said sidewalls fastened by welding with transverse elements, front and rear struts, welding lower longitudinal beams and the above mentioned sheep, and provided with a bottom made mainly of a decorative panel of durable material, and the frame base is provided with said guides located in the upper part of the base frame below said sidewalls and with said stops located in front of the base frame between the sidewalls and the guides, this said two side rollers with a flange mounted on bolts cantilever, fixed to the upper part of the rear rack of the sliding frame, rely on the said guides of the fixed frame-based They are made as movable supports of the sliding frame, allowing it to move horizontally to the mentioned stop when transforming the sofa into the "bed" position, while quick-release hooks are mounted on the outside of the sidewalls and guides for mounting the armrests, and front and rear of the base frame fixed supports are made, wherein said supporting rotary frame is fixed to the base frame by means of rotation axes mounted in arcuate slots made in brackets located on top of the said uprights in the rear of the base frame, and is arranged to rotate with the soft element relative to the base frame on the rotation axes in arcuate slots located in the brackets with the formation of a back when the position is "sofa" or with the formation of a horizontally located soft element in the "bed" position.

The disadvantage of this device is its relatively high complexity.

The closest in technical essence to the proposed one is the device [RU 2527721, C1, A47C 17/28, 09/10/2014], which is a multi-link lever-articulated mechanism including a base, a console, levers pivotally articulated into two quadrangles, the lower and upper gas springs, in this case, the base and the first group of levers form the first quadrangle, the second group of levers and the console form the second quadrangle, the lower gas spring is fixed to the lever and the base, the upper gas spring is fixed to the console and the lever, that the lever is L-shaped, and the arms are designed as U-sections.

The disadvantage of this device is the relatively narrow functionality, because, although the device allows you to raise the support for the mattress on a surface parallel to the floor, it does not allow this when using the internal space of the support for storing bedding.

In addition, the device has a relatively low safety of operation (use), since it is not safe from the unexpected movement of the support for the mattress down, which can lead to injuries, and when closed, it can strike the support for the mattress on the front king of the bed, thereby damaging the bedding.

The lifting mechanism of the closest technical solution allows you to raise the support for the mattress only in a horizontal position, which, on the one hand, which, on the one hand, makes it difficult to access the drawer, and, on the other hand, without a safety device, allows the support for the mattress vertical translational movements that can cause injuries when the support is in a horizontal position This also reduces the safety of operation.

In addition, in the closest analogue, jamming of the mechanism during folding is possible.

The objective of this utility model is to create a reliable, safe and easy-to-use mechanism characterized by reducing vibration, preventing jamming and allowing not only to raise the mattress support in a horizontal and raised position, but also to tilt the mattress support and also to fix it in the raised position to protect against unexpected movement in order to increase the safety of operation and the reliability of the device.

The technical result is to prevent jamming.

This technical result, as will be shown below, is achieved by reducing the structural elements and introducing a plate fixed in the lower part of the lever, a slider mounted on the upper gas spring, a locking lever connected to the slider, as well as an L-shaped lock and a safety pin placed on the lower end of the upper gas spring, which is connected to the base .. This allows you to smoothly fix the berth in a horizontal position without excessive vibration, which prevents jamming of the mechanism when unfolding and folding. .

The problem is solved, and the required technical result is achieved by the fact that, in a lifting device in the form of a lever-lifting mechanism containing a console, configured to attach to the lower surface of the support for the mattress, a lever, the upper and lower ends of which are connected, respectively, to the console and with the base, made in the form of a lining, rigidly fixed on the inner side of the longitudinal side of the bed, as well as the lower gas spring, the ends of which are connected to the lever and the base, and the upper gas spring, the upper end of which is connected to the console, according to a utility model, a plate fixed at the bottom of the lever, a slider mounted on the upper gas spring, a locking lever connected to the slider, as well as an L-shaped lock and a safety pin located at the lower end are introduced the upper gas spring, which is connected to the base.

in FIG. 5 - a mechanism for lifting a bed's berth, side view, with a fixed position of the locking lever;

in FIG. 6 is an example of a structural embodiment of the mechanism for lifting the bed.

In the drawing are indicated:

1 - lever, 2 - L-shaped lock, 3 - base made in the form of a lining rigidly fixed on the inside of the longitudinal section of the bed, 4 - locking lever, 5 - lower gas spring, 6 - upper gas spring, 7 - console, 8 - a slider, 9 - a plate, 10 - a safety pin, 11 - a longitudinal section of a bed, 12 - a support for a mattress (berth).

The mechanism for lifting the bed is made in the form of a lever-lifting mechanism.

It contains a console 7 made with the possibility of fastening to the lower surface of the support 12 for the mattress or bed.

In addition, the mechanism for lifting the bed berth contains a lever 1, the upper and lower ends of which are connected, respectively, to the console 7 and to the base 3, made in the form of a lining, rigidly fixed to the inner side of the longitudinal side of the bed 11.

The mechanism for lifting the bed berth also contains a lower gas spring 5, the ends of which are connected to the lever 1 and the base 3, and a gas upper spring 6, the upper end of which is connected to the console 7.

In addition to the above, the mechanism for raising the bed's berth includes a plate 9 fixed to the lower part of the lever 1, a slider 8 mounted on the upper gas spring 6, a locking lever 4 connected to the slider 8, as well as an L-shaped latch 2 and a safety pin 10, located at the lower end of the upper gas spring 6, which is connected to the base 3.

The mechanism for lifting the bed is a multi-link lever-hinge mechanism, including a quadrangle formed by a lever 1, a console 7, an upper gas spring 6 and a base 3, as well as a lever 4 locking, L-shaped latch 2 in the form of a plug and a safety pin 10 , representing the site of protection against injuries and protection of the king of the bed, as well as the lower gas spring 5.

The mechanism for lifting the bed is as follows.

To the bed base by fixing the base 3 to the elements of the bed are fastened, as a rule, two lifting mechanisms of the bed, the console 7 of which are attached to the lower surface of the support 12 for the mattress or bed.

Lifting the berth up is carried out by applying a force directed upward to the free end of the console 7. Further operation of the mechanism occurs under the influence of the lower 5 and upper 6 gas springs, which output the lever 1, the console 7 and the protection unit, consisting of the lever 4 of the locking, L-shaped the latch 2 in the form of a plug and a fuse pin 10, in the first phase of opening (Fig. 3). When acting on the console 7 in the downward direction, the upper spring 6 is compressed, and the lever 4 locking, due to its configuration, is latched onto the safety pin 10, thereby translating the quadrangle formed by the lever 1, the console 7, the upper gas spring 6 and the base 3 , in a momentless (dead) position.

The lower gas spring 5 additionally gives rigidity to the whole mechanism, ensuring its stability.

In this position, it is convenient to cover the sleeping surface.

With further action on the console 7, the lower gas spring 5 is folded, due to the release of the locking lever 4 from the fuse pin 10, by resting on the plate 9, made in the shape of a rectangle, for example with dimensions 20 × 50 × 5, and fixed to the lever 1 by welding , and thus the mechanism smoothly transitions to the folded position, as shown in FIG. 2.

The practical applicability of the claimed mechanism for lifting the bed is shown in the following example (Fig. 6).

To the two longitudinal sections of the bed by fixing the base 3 are attached two lifting mechanisms of the bed. To their consoles 7 a sleeping place is attached.

The mechanism for lifting the bed's bed includes a quadrangle formed by a lever 1, 400 mm long, a cantilever 7, a length of 480 mm and made of a 32 × 32 mm corner with a wall thickness of 4 mm, an upper gas spring 6, a plate 9 with a length of 50 mm and a thickness of 5 mm . The lower gas spring 5 at one end is fixed to the lever 1 at a distance of 50 mm from the lower edge, the other on the base 3.

Testing of the mechanism showed that it allows you to smoothly fix the bed in a horizontal position without excessive vibration, prevent the mechanism from jamming when unfolding and protect the bed cotters when folding by reducing the vibration of the mechanism when folding, which eliminates damage to the casing, and is also technologically simple to manufacture in production. provides reliability and safety, ease of use, does not spoil the casing of the drawer, and is also technologically simple to manufacture in production.

The proposed mechanism design provides compact folding of the multi-link lever-articulated mechanism and, when unfolding, eliminates the movement of the berth down when the force is applied to it. Fixation of the protection mechanism occurs in the horizontal position of the berth and ensures the reliability of the fixation and silent operation.

Thus, due to the fact that a plate fixed in the lower part of the lever, a slider mounted on the upper gas spring, a locking lever connected to the slider, as well as a L-shaped latch and a safety pin located at the lower end of the upper gas spring, which is connected to the base, ensures the achievement of the required technical result, which is to prevent jamming.
