Description

FIELD OF TECHNOLOGY TO WHICH A USEFUL MODEL IS

The utility model relates to cabinet furniture, namely to beds combined with “cabinet” type cabinet furniture, etc. Such a bed in the folded position occupies the minimum dimensions in the space of the room, does not interfere with cleaning and other activities.

BACKGROUND

Known folding bed, including a rotary frame, two fixed supports and a rotary mechanism containing two gas compression springs mounted on the sides of the rotary frame of the bed. In a hinged bed, the first fastening element, for fixing one end of the gas spring of the rotary mechanism, is mounted on the rotary frame at a point with a displacement relative to the head of the bed greater than the offset of the bearings, and the second fastening element for fixing the second end of the gas spring is mounted on the flange of the rotary mechanism below horizontal a 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. (Description of the invention to the patent of the Russian Federation No. 2284138, IPC A47C 17/38, published September 27, 2006).

A disadvantage of the analogue is the occurrence of sliding friction of surfaces during the operation of the transformation mechanism, namely the instability and weak efforts of gas springs, which can lead to deterioration of the sliding surfaces of the folding bed.

Known transformable bed containing a fixed base, including side 1, rear 2 and lower 3 walls, and a folding bed, including a mattress 4, placed in the box, consisting of side 5 and end 6 walls, as well as the bottom 7 with a supporting leg 8, and connected to the side walls 1 of the base by means of a bed transformation mechanism containing at least two swivel joints including an axis 9, conjugated with the side walls 1 of the base and with the side walls 5 of the box, as well as at least two gas x springs (four in the description) 10, 11, 12, 13, pivotally connected to the side walls 5 of the box, the axis 9 is paired with the side walls 1 of the fixed base by means of a rigid connection, and with the side walls 5 of the box pivotally. At the same time, levers 19, 20, 21, 22 are rigidly attached to the axis, the free ends of which are pivotally connected to gas springs 10, 11, 12, 13. At the same time, a space 31 is formed between the mattress 4 and the bottom 7 of the box, in which the bed transformation mechanism is located ; Hinged panels 32, the height of which exceeds the height of the mattress 4, can be pivotally attached to the side walls 5 of the box. (Description of the utility model for RF patent No. 88922, IPC А47С 17/40, published on November 27, 2000).

A disadvantage is the occurrence of sliding friction of surfaces during the operation of the transformation mechanism, namely the instability of the force of gas springs, which can lead to deterioration of the sliding surfaces of the folding bed.

A smart bed is known, including a wardrobe and a bed frame, comprising a cabinet body that is movably connected to the front end of the bed through a supporting buffer connecting structure. The bed can rotate around the rotation shaft. When the bed is not used, it is installed in the cabinet, when used, the movable support extends in the bed and the bed rotates slowly around the shaft under the action of gravity and the buffer cylinder. The movable support always remains upright by gravity and rotates to the floor in accordance with the rotation of the bed, so that the movable support is the support of the bed. (CN 202653648 U, Cl. A47c 17/02, 01/09/2013).

In the proposed technical solution, taken as a prototype, the bearing is located on the bottom of the cabinet, i.e. on the part fixed to the wall and acts as a vertical bearing to support the bed.

DISCLOSURE OF A USEFUL MODEL

The objective of the proposed technical solution is to increase the operational characteristics of furniture, due to the reliability and quality of transformation due to the smooth and easy folding and lifting of the bed.

The technical result of the task is aimed at improving the design of the transformable bed, by eliminating friction, which increases the smoothness of the transformation.

The solution to this problem is achieved by the fact that in the known design containing a fixed base including side walls, a rear wall and a folding berth, including a box consisting of side walls and end walls, as well as a bottom with a hinged supporting leg; the box is connected to the side walls of the base by means of a bed transformation mechanism comprising two swivel-joints, including an axis mating with the side walls of the fixed base and with the side walls of the box, by means of a rigid connection, which is a support bar; There are also four gas springs connected to the side walls of the box by means of hinges, respectively, the bearing is fixed on the box of the folding berth.

It differs from the prototype in the presence of a bearing assembly with a bearing pressed inside the hinged-rotary connection. The use of a bearing assembly with a bearing pressed inside allows eliminating friction and improving the smoothness of transformation, as well as increasing the service life.

Wherein:

- each element of the transformation mechanism is connected at one end to a support bar installed in the lower part of the side wall of the cabinet, and the other end to a support bar mounted on the box sleeper,

- gas springs are fixed in the transformation mechanism in a compressed state with the possibility of their expansion after the installation of the transformable bed,

- gas springs are located (combined) in two together, which will enhance the action of gas springs, as well as increase the service life and provide additional security,

- transformable bed is made with a facade.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present utility model is illustrated by a specific example of execution, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the required technical result.

IMPLEMENTATION OF A USEFUL MODEL

Transformable bed, made in the form of a wardrobe, - folding bed, includes:

1. The side wall.

2. The back wall.

3. A folding berth.

4. Box.

5. Folding support leg.

6. Facade.

7. The mechanism of transformation of the bed.

8. Swivel joint.

9. Gas shock absorbers.

10. Support plate of the housing.

11. The basic level of a berth.

12. The axis of rotation.

13. Bearing assembly.

14. Pens.

15. The bearing.

The essence of the transformable bed is that it contains a fixed base, including side walls 1, rear wall 2, a folding sleeping 3 place, including a box 4, consisting of side walls and end walls, as well as a bottom with a hinged supporting leg 5; the box is connected to the side walls of the base through the mechanism of transformation of the bed 7.

The mechanism for transforming the bed 7 contains two swivel joints 8 made of steel, including a bearing assembly 13, with a pressed bearing 15, an axis 12, conjugated to the side walls of the fixed base and the side walls of the box, and four gas springs (shock absorbers) 9, with a calculated linear force of 400-2500 N.

Gas springs are connected to the side walls of the duct through hinges, respectively.

The axis 12 is connected to the side walls of the fixed base 1 and to the side walls of the duct 4 by means of a rigid connection, which is the support strips 10 and 11, and the axis is interfaced to the side walls of the duct through hinges.

Gas springs 9 are located (combined) two together.

Gas springs are fixed in the transformation mechanism in a compressed state with the possibility of their expansion after installing a transformable bed.

Transformable bed is made with a facade of 6.

Use a transformable bed as follows.

The transformable bed 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 must be rigidly fixed.

Unfolding the transformable bed begins with pulling the folding bed 3 with the help of handles 14 until the box reaches a comfortable position to move the supporting leg 5 from the position shown in FIG. 7 to the position shown in FIG. 6, then continue lowering the bed.

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 (not shown in the figure) that hold the pillows and blanket (when the bed is upright) 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.

The design of the cabinet with a folding bed provides compactness and allows using it in bedrooms, children's rooms, living rooms, etc.

The presence in this design of the mechanism for transforming the bed, made in the form of two symmetrically located swivel joints and four gas shock absorbers with an estimated linear force of 400-2500 N, can significantly reduce the efforts made when transforming a bed to a bed.

The presence of the facade allows you to give the product the most aesthetic appearance, while the implementation of the facade fixed to the box provides compactness when opening a berth.

Thus, the use of the proposed transformable bed will significantly improve the operational characteristics of furniture by ensuring the reliability and quality of transformation, by smoothly and easily folding and lifting the bed.
