Description

The technical solution relates to household items and relates to children's furniture, in particular cradle beds for newborns and young children.

A known cradle bed containing a cradle suspended on a support of a crossbeam, comprising a front, rear and two side walls having the shape of a trapezoid, and a cradle suspension means including rods, the lower parts of which are elements of the side walls (see US patent 1715600, A47D 9/00, 1929).

This device does not provide adequate ease of use. Convenience in operation is understood as comfort for a baby, which, as a rule, in modern conditions does not swaddle tightly and can sit down, get up and walk in a cot; Convenience for caring for a child, which consists in the ability to easily and quickly install a cradle bed in the desired place, disassemble it for transportation, and also use the bed as an arena, freeing it from the corresponding suspension or swing devices.

Also known is a cradle of rigid construction having a removable type platform combined with a crib (French patent No. 1019031, A47D 9/02 of 1953). However, this cradle requires a specially made bed, the baby is rocked by turning the cradle around its longitudinal axis, which causes the baby to roll over, the cradle does not have means to fix toys over the baby, cannot be used as an independent item and requires storage space when needed it disappears.

The prior art Russian analogues of the claimed technical solution.

For example, a cradle for combining with a removable type baby bed is known, comprising a rigid platform having communication means with the bed body with the possibility of oscillatory movements. The cradle platform is equipped with a means of stabilizing it in a horizontal position, made in the form of sliders rigidly attached to the platform to interact with the vertical elements of the bed, forming guides for the sliders. The means of communication of the platform with the bed body, providing the possibility of oscillatory movements of the platform in the vertical plane, are formed by elements with elastic tensile or compressive deformations, or with a combination of them (RU 2079281, A47D 9/02, 1997.05.20) (the closest analogue).

Also known is a children's cradle bed containing a cradle suspended on a support of a crossbeam, including a front, rear and two side walls having the shape of a trapezoid, and a cradle suspension means including rods, the lower parts of which are elements of the side walls. The large bases of the trapezoidal side walls of the cradle are located in its lower part, and the bottom is made of prefabricated flat inserts and a base that engages with rods, while the crossbar of the supports has wedge-shaped samples corresponding to the shape of the sections of the supports (RU 2096014, A47D 9/00, 1997.11.20).

Common disadvantages for the above technical solutions is their structural complexity, which determines the large labor costs in the implementation of the fluctuation of the beds and significant efforts made to motion sickness of the child.

The task to which the claimed technical solution is directed is to develop the design of the crib, the operation of which will be greatly simplified and the process of motion sickness of the child will be facilitated and thus the most comfortable conditions for falling asleep will be created.

The technical result of the claimed solution is to simplify and facilitate the process of fluctuation of the crib, as well as, as a result, the creation of the most favorable conditions for motion sickness of the child.

This problem is solved in that the crib bed, which contains a stationary bed base and an oscillating body, according to the claimed technical solution, additionally contains a pendulum mechanism, which is a pendulum - a rectangular oriented plate made with holes at the ends, bearings installed into the aforementioned pendulum openings and the corresponding openings made in the base of the bed and the pillars of the bed body, as well as the axles - fixing elements copies, while a rectangular-oriented plate is made up to 180 mm long, up to 35 mm wide and up to 10 mm thick, and holes in the plate are made up to 16 mm in diameter with a center distance between them of up to 150 mm.

In addition, the pendulum may be made of metal, wood or polymer.

As shown by the practical use of this technical solution, when it is implemented with the indicated ranges of values of a rectangular oriented plate, the highest performance characteristics are achieved.

From the point of view of geometry, the indicated size range of the pendulum achieves the fact that the suspension points of the rocking chairs are transferred to a level higher than the level of the center of gravity of the crib as a whole, due to which the whole structure is in a position of stable equilibrium, which ensures smoothness and softness of oscillatory movements when swinging.

First of all, this is expressed in the fact that the process of oscillating a crib is greatly simplified by reducing the applied effort with which the cradle sways. It becomes much easier to rock the cradle, which is so important for a young mother or an elderly nurse.

The following is information confirming the influence of a number of features of the utility model formula on the achieved technical result - simplification and facilitation of the process of crib vibrations (see Table 1), obtained empirically.

As can be seen from Table 1 when implementing the “8” motion sickness mode, when it is known that the most favorable mode of motion sickness for a child is the mode in which the frequency of crib vibrations is in the range of values up to 132-130 vibrations per minute (62-67 pairs of reciprocating movements cribs: “round-trip”), the parameters of the crib elements (given in the table) correspond to the values given in the formula of the utility model.

The fame of this most favorable regimen is confirmed by our tests, according to which, if in a normal situation (the child is not hungry, not sick and there are no other force majeure circumstances), the child should be rocked with this regimen, the probability of his fast falling asleep is close to 100 %

The claimed technical solution is illustrated by graphic materials.

In figure 1, 2 is a fragment of the rack casing of the crib, the pendulum mechanism and the base element of the crib,

In figure 3, 4 - pendulum mechanism.

2 ₁ and 2 ₂ - elements of the base of the bed,

3 ₁ - pendulum mechanism

3 ₂ - pendulum,

4 ₁ and 4 ₂ - holes for mounting bearings and axles - fasteners,

5 ₁ and 5 ₂ - axis - fasteners,

6 - holes in the pendulum,

7 ₁ and 7 ₂ - bearings.

The following is one of the possible ways to implement the claimed technical solution, in no way limiting all possible options for its implementation.

A bearing (not shown) is installed in the hole (4 ₂ ) made on the element (2 ₂ ) of the stationary base of the crib.

Then, by means of an axis - a fastening element (6 ₂ ) and a bearing (7 ₁ ), placed in the hole (6), made with a diameter of up to 16 mm of the pendulum, the pendulum (3) is installed in a vertical, working position on the axis - the fastener (5 ₂ ) already in the hole (4 ₂ ) and attached to the base of the crib.

The pendulum is made in the form of a rectangular oriented plate with a length of up to 180 mm, a width of up to 35 mm and a thickness of up to 10 mm, and the holes in the plate are made with a diameter of up to 16 mm with a center distance between them of up to 150 mm.

The choice of the size of the pendulum is due, as noted above, established experimentally in the process of prolonged use of the laws between the size of the plate and the ease with which the cradle oscillates.

Then, in the bearing hole (7 ₂ ) installed in the hole (6) of the pendulum (3 ₂ ), an axis is mounted - the fastener (5 ₁ ). And already on this axis is the fastening element (5 ₁ ), the bed body pillar ( ₁ ) is installed by means of the hole 4 ₁ made in it and a bearing (not shown) placed in it.

After installing all 4 racks of the movable bed body on the corresponding pendulum mechanisms (there are also 4 of them), the axles, fasteners, of the bed rack are finally fixed.

Thus, it turns out that the movable crib body, which is a rectangular box with vertical struts placed in its corners, is suspended on 4 pendulum mechanisms that ensure its oscillation.

The cradle bed is assembled and ready for use. The assembly of the crib-cradle can be carried out in a different order, more accessible to the user.

As can be seen from the above, this solution really simplifies the process of oscillation of the crib body.

Thus, the implementation of the crib-cradle simplifies the process of its operation, mainly its fluctuations and motion sickness of the child.
