Description

Chair

It relates to the technology of chairs used to lay infants.

Infants have an empirical rule that they are easy to lie down when they are swung up, down, left and right. As a more specific example, when an adult is hugging and shaking lightly, or sitting on a child seat of a car and shaking with the vibration of a running car, the infant will fall asleep immediately.
On the other hand, it is very troublesome for an adult to always hold an infant or get in a car every time he lays him down.

Therefore, in recent years, a technique such as a rocking sway that automatically sways has been proposed in consideration of the reduction in time and effort of sleeping (

DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described with reference to the drawings.
(Structure of the chair according to the present embodiment)
The structure of the chair 1 according to the present embodiment will be described with reference to FIGS. 1 to 5 are views showing one embodiment of the chair 1.

The chair 1 is an instrument for a person 10 holding an infant 8 to sit down and to lay the infant 8 comfortably by swinging his / her body up and down while holding the infant 8. Since the infant 8 is shaken up and down while being held by the person 10, it is prompted to fall asleep while shaking while feeling the warmth of the human skin. On the other hand, the person 10 who wants to lie down on the infant 8 can swing the infant 8 up and down while sitting on the chair 1 instead of standing, so that the physical burden is small.

1 to 5, the chair 1 includes a seat portion 2, a grounding portion 4, and an intermediate portion 6. The seat portion 2 is a portion that contacts the buttocks when a person (particularly a person holding the infant 8) 10 sits down. The seat 2 is also referred to as a seating surface. The seat 2 swings up and down as the person 10 swings his / her body up / down / left / right to move the center of gravity.

The grounding unit 4 is a part in contact with the floor or the ground when the chair 1 is placed on the floor or the ground. The grounding unit 4 is sometimes called a leg of the chair 1. The intermediate part 6 is a part that connects the seat part 2 and the grounding part 4.
Next, the principle of operation in which the seat 2 swings up and down will be described.
When the center of gravity of the person 10 is moved while sitting on the chair 1, the seat 2 moves to the lower position or the upper position and swings in the vertical direction.

Such a swinging motion of the seat portion 2 may be a motion caused by the seat portion 2 itself being bent or returning to its original shape based on the movement of the center of gravity of the person 10. At this time, the elastic force by which the seat portion 2 itself bends or returns to the original shape can be appropriately adjusted according to the weights of the infant 8 and the person 10 and the swinging width that the infant 8 can easily fall into.

Further, the swinging motion of the seat portion 2 may be a motion generated by the middle portion 6 extending and contracting in the vertical direction based on the movement of the center of gravity of the person 10. The elastic force that expands and contracts in the vertical direction of the intermediate portion 6 can be adjusted as appropriate according to the weight of the infant 8 and the person 10 and the swing width that the infant 8 can easily fall into.

Further, the swinging motion of the seat portion 2 may be generated based on the effects of both the elastic force caused by the bending of the seat portion 2 and the elastic force caused by the expansion and contraction of the intermediate portion 6 described above. Even in this case, the elastic force included in the seat 2 and the intermediate portion 6 can be appropriately adjusted according to the weight of the infant 8 and the person 10 and the swing width at which the infant 8 can easily fall asleep.

As shown in FIG. 1, the chair 1 may have a configuration in which the intermediate portion 6 includes a spring member 12. As shown in FIG. 2, the chair 1 may have a configuration in which the intermediate portion 6 includes a suspension member 14. The chair 1 shown in FIGS. 1 and 2 is provided with an elastic force in the intermediate portion 6 for swinging the seat portion 2 in the vertical direction.
On the other hand, as shown in FIG. 3, the chair 1 may be in the form of an ottoman.

On the other hand, as shown in FIG. 4, the chair 1 may be in the form of a rubber air cushion. Although not shown, the chair 1 is in the form of a so-called balance ball which is a spherical elastic body. There may be.
Further, as shown in FIG. 5, the chair 1 may have a form in which the side surface of the intermediate portion 6 has a bellows shape and exerts an elastic force.
In the chair 1 shown in FIGS. 3 to 5, at least one of the seat portion 2 and the intermediate portion 6 is provided with an elastic force for swinging the seat portion 2 in the vertical direction.
(How to use the chair according to this embodiment)

The use method of the chair 1 according to the present embodiment will be described with reference to FIG. FIG. 6 is a diagram for explaining how to use the chair 1 shown in FIG. Here, although the usage method of the chair 1 illustrated in FIG. 1 is demonstrated, it is the same as that of the following usage method also about the usage method of the chair 1 illustrated in FIG.

The person 10 who wants to lay down the infant 8 sits down while holding the infant 8 in the seat 2 of the chair 1. At this time, the seat 2 is stabilized at a predetermined position (height) even if it is slightly depressed.

Next, the person 10 moves his / her center of gravity while sitting down on the seat portion 2 to cause the intermediate portion 6 to perform expansion / contraction, and accordingly, the seat portion 2 swings up and down. . At this time, the magnitude of the swing width of the seat portion 2 (intermediate portion 6) can be appropriately adjusted depending on how the body of the person 10 moves (the amount of movement of the center of gravity).
The person 10 keeps shaking his / her body up and down until the baby 8 who has been held falls asleep. When the baby 8 falls asleep, the person 10 stops the vertical movement.

By using the chair 1 to lay down the infant 8 in this way, the infant 8 can be encouraged to fall asleep without feeling uncomfortable, and the physical burden on the person 10 who lies down can be reduced.
(Summary)
The chair 1 is swayed in a state where the person 10 feels the safety and warmth of the human skin, thereby prompting the infant 8 to fall asleep comfortably.
The chair 1 can lay the infant 8 while the person 10 who lays the infant 8 is sitting down, so that the physical burden on the person 10 is reduced.

Although the embodiment of the present invention has been described in detail above, the present invention is not limited to the specific embodiment, and various modifications are possible within the scope of the gist of the present invention described in the claims.・ Change is possible.
