Description

The utility model relates to children's furniture, in particular to children's furniture with a side railing, equipped with a device for rocking a crib and lulling a child.

A device for motion sickness of the child, containing a cot with legs and located under the bed swing mechanisms associated with the front legs of the crib (see, for example, the description of the invention to US patent No. 4793080, class A47D 9/02, 1988).

The disadvantages of this solution are the lack of mobility of the crib, which does not allow to increase the effectiveness of motion sickness of the child.

There is also known a device for motion sickness of a child, containing a crib with legs and rocking mechanisms located under the bed, connected with the front legs of the crib, each of which is made in the form of a plate, along the edges of which holes are made with fasteners missing in opposite directions (see, for example , description of the invention to the patent of the Russian Federation No. 2055511, CL A47D 9/02, publ. 10.03.1996).

The disadvantage of this device is a rather complicated design and insufficient reliability of operation, the need for multiple tilt to the child, which causes fatigue and reduces its attractiveness .;

The closest known for its technical essence and the achieved result is a device for swinging a crib, selected as a prototype, containing a housing fixed to the support element with a drive mechanism for limited movement and ensuring a smooth change in the amplitude of auto-oscillations of the crib to the maximum (see, for example, description inventions to the patent of the Russian Federation No. 2239346, class A47D 9/02, publ. 10.11.2004).

The disadvantages of this device are the rather complicated massive design of guide bushings and vane rollers, which negatively affects the operational reliability in general, as well as the lack of the possibility of automatic self-oscillating reciprocating movement of the crib and lulling the child.

The essence of the claimed utility model is expressed in the aggregate of essential features sufficient to achieve the technical result provided by the proposed utility model, which is expressed in increasing operational reliability by simplifying the design and making it possible to automatically oscillate the reciprocating movement of the crib and lull the child, as well as to enable approach to the child in the functional working area of a person and increase the convenience of knowledge.

The specified technical result is achieved in that the device for rocking the crib containing a housing fixed to the support element with a limited movement drive mechanism and providing a smooth change in the amplitude of the crib’s self-oscillations to a maximum is equipped with an electric drive mechanism motor with a crib auto-oscillating mode regulator, the drive mechanism itself made in the form of a drum with a flexible rod fixed to the shaft of an electric motor for kinematic communication with a children's with a rim and ensure the possibility of its reciprocating movement, and the regulator of the self-oscillatory movement of the crib is made in the form of a microprocessor circuit equipped with sensors for monitoring the self-oscillatory movement.

The claimed combination of essential features is in direct causal relation to the achieved result.

Comparison of the claimed technical solution with the prototype made it possible to establish compliance with its criterion of "novelty", since it is not known from the prior art.

The proposed device is industrially applicable, because can be implemented by existing technical means.

Thus, the proposed technical solution meets the established conditions of patentability of a utility model.

The other known technical solutions for a similar purpose with similar significant features by the applicant was not found.

Figure 1 presents a device for rocking a crib, a General view, figure 2, 3 and 4 is a diagram of the controller of the mode of self-oscillating reciprocating movement of the crib.

A device for rocking a crib contains a housing 2 fixed to the support element 1 with a drive mechanism for limited movement and ensuring a smooth change in the amplitude of auto-oscillations of the crib to the maximum.

The proposed device is equipped with an electric motor 3 of the drive mechanism with a regulator of the self-oscillatory movement of the crib, the drive mechanism is made in the form of a drum 5 mounted on the shaft 4 of the electric motor 5 with a flexible rod 6 for kinematic communication with the crib 7 and the possibility of its reciprocating movement, and the controller self-oscillatory movement of the crib is made in the form of a microprocessor control circuit 8, equipped with control sensors (not shown) Yelnia displacement.

The operation of the device is as follows.

When the microprocessor control circuit for controlling the mode of self-oscillatory movement of the crib is turned on, the electric motor 3 is turned on, the drum 5 starts to rotate on the shaft 4, and when the flexible coupling 6 is tensioned, the crib 7 deviates from its initial equilibrium state, determined by the electric motor power and the setting of the sensors for controlling the self-oscillatory movement, while the electric current reaches its maximum value and turns off, the polarity of the connection changes, at which The th electric motor turns on and the crib returns to its original position, continuing to move in the opposite direction. There is a reverse rotation of the drum 5 and a self-oscillating reciprocating movement of the crib 7 in the self-oscillating process. In this case, the crib has the ability to swing, similar to lulling a child.

Thus, the use of the proposed device provides increased operational reliability by simplifying the design and providing the possibility of automatic self-oscillating reciprocating movement of the crib and lulling the child, as well as providing the possibility of approaching the child in the functional working area of a person and improving ease of use.
