The invention relates to furniture industry and can be used in hotels, rooms for mothers and children, on the transport.

Known children bed, containing a bed, on a path which has mesh fencing (U.S. patent No. 437618, CL 5/99, published. 15.03.83), as well as the bed containing the front and back of the backrest and a bed having a cavity with a pull-out containers (U.S. patent No. 3745596, CL 5/308, published. 1973).

Closest to the present invention is a bed containing the front and back and the bed, which is further provided with pivotally mounted on one of the backs cradle which is pivotally connected one end of the holders, and in the side walls of this back and the bed is made connecting the guide grooves, and the holders of its other ends are located in the slots for movement along them and fixing in position.

The disadvantages of specified beds are the complexity and the complexity of installation, and minimize the cradle associated with the movement of the holders of interconnected grooves of the bed and back. The end holders takes place when installing the cradle of first horizontal grooves of the bed, then in the vertical grooves of the back, and Vice versa. As the holder of the force of the weight perpendicular component of which the servant of the melt to remove the holder from the groove, the holders must be maintained by hand.

The purpose of the invention is ease of use.

This objective is achieved in that the holders are made of tubes of different diameters that are members of one another so that they can move relative to each other and fixing in position, the guide grooves of the back outer side is made smaller than the ends of which move in their holders. This allows you to change the length of the holders when installing and dismantling the cradle and eliminates the need for guide grooves of the bed. In this section of the guide grooves and form holders selected so that during movement of the end holder of the groove before installing it in a fixed position to balance the force acting to disengage the holder from the slot.

Figure 1 shows the bed with the cradle in position, front view; figure 2 - the cradle in the off position; figure 3 shows the forces acting on the holder; figure 4 - cross section of the groove of the back holder.

The bed contains the backrest 1, the top of which hinge 2 set the cradle 3.

The cradle 3 hinge 4 is connected with one end of the brackets 5. In the side wall of the backrest 1 has guide grooves 6.

When moving the holder 5 of the groove 6 on the center of gravity of the holder Of the force of gravity P, which can the be decomposed into two mutually perpendicular forces P 1and R2.

P2balanced force R3equal in magnitude and opposite in sign to the current side of the hinge 4.

The power of the P1acting to disengage the holder from the groove, the proposed cross section of the groove and the holder, is balanced by the power of R4effect at the end of the holder 5 from the outer wall of the groove.

P1=P4=Px cosα1-Px cosα2.

The device works in the following way.

The cradle 3 is lifted in a horizontal position, while the holders are rotated on the hinges 4 are moved along the guide grooves 6 and fixed.

In the claimed technical solution, the application of the holder of several tubes of different diameters that are members of one another so that they can move relative to each other and fixing in position for installation of the cradle is a new feature.

Therefore, the specified hallmark gives the basis to consider the claimed technical solution meets the criterion of "novelty".

In the claimed technical solution there are other signs that are not found in the known solutions:

- the use of the proposed cross-section of the groove;

- application form holder with thickening at its end, which moves within the guide groove.

On the basis of the years of the above we can conclude, that the claimed technical solution meets the conditions of patentability:

- is new, because it is not known from the prior art;

- involves an inventive step;

industrially applicable.

The bed containing the back, a cradle pivotally mounted in the upper part of the backrest can be moved in a horizontal position by means of holders pivotally connected at one end to the frame cradles, and the other is installed in the guide grooves can move along them and fixing in position, wherein the guide grooves are made in the side walls of the back, the holders made in the form of tubes of different diameters that are members of one another can be moved one relative to another and fixing in position at the ends of the holders moving in grooves have a thickness larger than size guide grooves back outside.
