Description

The invention relates to products of light industry, in particular to pieces of furniture, in particular to beds, which can be used both at home and in hotels, especially in rooms where there is a shortage of free space.

Known hinged wall bed (SU, 1837832, class A47C 17/40, 1993), including a frame with a mattress, mounted by hinges mounted on the corners of the frame adjacent to the wall side of the frame, on a pair of hinges. Rods are pivotally attached to the same brackets, the opposite ends of which are also pivotally and symmetrically attached to the sides of the frame, forming the axis of rotation of the frame parallel to its wall side.

However, this design of the bed is not compact enough due to the fact that when it is removed it occupies a significant place on the floor, equal to at least the height of the bed in the working position.

Also known is a folding wall bed (RU, 2171087, class А47С 17/40, 07/27/2001), containing a frame in the form of a rectangular wall structure, on which a bed with a mattress is located. A bracket is attached to the wall, to which the rod is hinged, also pivotally attached to the side of the frame. A stand is attached to the wall, on the lateral surface of which a roller support is rolled. After the roller support reaches the top of the rack, it rolls onto the upper end surface of the rack and occupies the working position. At the same time, support legs are tilted at the side of the frame that is far from the wall, and the wall side of the frame fits tightly between the wedge-shaped stops that perform the function of the latches of the frame extreme position.

However, this wall bed in the assembled state is not compact enough, and its design is complicated.

A known lifting bed (RU, 2138976, class A47C 17/38, A47C 17/52, 1999), comprising a frame with a mattress and a frame transformation device, which is made in the form of a frame rotation unit with a counterweight. In addition, the bed is equipped with a L-shaped movable rear back with the ability to move it along the vertical guides located on the side panels.

All the above designs of lifting beds are transformed into an upright position, occupying in the assembled state a place at least equal to the height of the frame with the mattress, mainly 600 mm, which corresponds to the standard design of the depth of the wardrobe, i.e. well-known designs are non-compact and quite laborious during transformation.

As a prototype, the invention was chosen - a bed (RU 21335, class A46C 17/38, 01/20/2002), containing a base that is supported along one of its edges of the vertical frame structure and can be lowered down to the position of use and lifted up along one of the sides frame structure in the storage position, while maintaining a substantially horizontal position. On the opposite side of the frame structure there is another element of furniture, combined with the working mechanism of the bed and moving in the opposite direction relative to the bed, as a counterweight. Another element of furniture, as opposed to a bed, is for use during the day. The frame structure serves as a support for the bed base, resisting the tipping effect of the frame structure when the base is in the storage position. The frame structure includes at least one element having a trapezoidal configuration in cross section along the depth of this frame structure. The structure also includes a mechanism designed to facilitate the movement of the base, for example, in the form of a counterweight, connected to the corresponding system by flexible ties and pulleys.

The main disadvantage of the known bed is the bulkiness of its design, which occupies a fairly large place in the room. In addition, to counterbalance it from the opposite side of the frame structure, it is assumed that another item or element of furniture is installed, which is not always acceptable. The need to balance the bed on the opposite side of the frame structure with another element of furniture affects its lack of stability and reliability during operation.

The objective of the invention is to increase the reliability and convenience during its operation.

The technical result of the invention is to increase stability during descent, raising the bed.

The task and the specified technical result is achieved by the fact that in a lifting bed containing a frame with a mattress and a mechanism for moving the frame made with the possibility of vertical reciprocating movement and containing flexible connections connecting the frame with a counterweight, guide elements interacting with flexible connections, according to the invention, the flexible connections are combined into one flexible connection, including three pairs of vertical sections located on the trajectory of movement of the three corners of the frame, and two pa ry horizontal sections parallel to the adjacent sides of the frame and located at the same level, the corners at the corners are rigidly connected to the vertical sections of the flexible connection, and the guiding elements contain three pairs of cable blocks with horizontal axes of rotation located above the three corners of the frame, and one cable block with a vertical axis of rotation, and the counterweight is rigidly fixed to two adjacent vertical sections of flexible communication with the ability to move in the direction opposite to the direction of movement of the frame. Moreover, horizontal sections of flexible connections are located at the level of the floor and ceiling. The proposed device allows easy vertical reciprocating movement of the frame, completely freeing up when it is in the upper part of the floor occupied by it in the lower position, due to the design of the mechanism for moving the frame containing a cable block system, which is compact and does not take up much space. The location of the elements of the cable system on the ceiling and on the floor directly against the walls provides the maximum release of the space as a result of lifting the bed to the ceiling. In both end positions, the frame is locked with latches, the design of which may be different. The clamps will ensure the safety of the structure during operation.

The invention is illustrated by drawings, where in Fig.1 - a lifting bed located on the floor; figure 2 - a bed with vertical guides; figure 3 - lifting bed with a weight compensation device in the form of a winch with a manual drive; figure 4 - lifting bed with a weight compensation device in the form of a winch with an electromechanical drive; figure 5 - lifting bed containing two closed cable systems with horizontal floor sections of flexible connections; figure 6 - lifting bed containing two closed cable systems with horizontal ceiling sections of flexible connections; figure 7 - lifting bed with one cable system with horizontal floor sections of flexible connections; on Fig - lifting bed with one cable system with horizontal ceiling sections of flexible connections.

A lifting reciprocating bed contains a frame 1 with a mattress 2, mounted on flexible ties 3 connected to a device 4 for weight compensation of the frame 1 with a mattress 2, which can be made in the form of a counterweight (Fig. 1, 2, 5, 6, 7 , 8), or in the form of a winch with a manual drive 5 (figure 3), or in the form of a winch with an electromechanical drive 6 (figure 4). Flexible connections 3 contain vertical sections 7, on which the frame 1 is attached, vertical sections 8, with which the weight compensation device 4 interacts, as well as horizontal sections 9. Flexible connections 3 interact with ceiling guide elements 10 (Figs. 1-8), floor guiding elements 11 (Fig.5-8) and with a guiding element 12 with a vertical axis of rotation (Fig.7, 8). In one of the designs, the bed may contain fixed vertical guides 13, interacting with rollers 14, mounted on the frame 1 (figure 2). The bed contains latches 15 extreme positions of the frame 1 (Fig.1-8). As flexible connections 3, ropes or drive chains can be used, and rope blocks or sprockets, respectively, as guide elements.

The work of the lifting bed is illustrated in figure 1, 2, 5, 6, 7, 8.

To raise the frame 1 from the lower position to the upper, it is necessary to move the latches 15 of the frame 1 to the "free" position and, holding the frame 1, allow it to take the upper position "under the ceiling", into which the frame 1 will move, thanks to the counterweight 4 connected to the frame 1 by means of flexible connection 3. On the vertical sections 7 of flexible connections 3, moving upwards, the frame 1 is fixed, and on two of the three vertical sections 8 of flexible connections 3, moving down, a counterweight is fixed 4. In the upper position, the frame 1 locks 15. To move the frame 1 to the lower position "on the floor", the latches 15 must be moved to the "free" position and a downward force exerted on the frame 1 that is greater than the difference between the weights of the counterweight 4 and the frame 1 with the mattress 2 and bedding and the friction force until the frame 1 reaches its lowest position. In the lower position, the frame 1 is fixed to prevent it from returning to the upper position.

The translation of the bed in the upper position by means of a winch 5 with a manual drive and an electromechanical drive 6 is carried out in a similar way.

Raising the bed vertically upward to the ceiling ensures complete release of space after using the bed, expanding the useful area of the room. In this case, the bed can easily be returned back to the floor. The simplicity and convenience of a lifting bed were confirmed by a prototype.
