DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air massage device for performing massage by inflating and deflating an air bag.

[0002]

2. Description of the Related Art As this kind of air massage device,
For example, a chair-type air massage device as shown in FIG. 8 has been considered.

In the chair-type air massage apparatus shown in FIG. 8, a backrest 201 is attached to the rear edge of the seat 200 so as to be able to rotate back and forth. While arranging a plurality of air bags 203a to 203f,
The air supply / exhaust device 204 and each of the air bags 203a to 203f are connected by air hoses 205a to 205f.

Further, in this air massage device, each air bag 203a-2
03f is expanded and contracted in order.

[0005]

However, in this air massage device, since the air bags 203a to 203f extend to the left and right of the seat portion 200 and the backrest portion 201, the air bags 203a to 203f are used by the user. However, the effect of simply pressing the back and the like of the person cannot be obtained, and the massage effect of grasping and rubbing the body cannot be obtained.

An air massager disclosed in Japanese Patent Application Laid-Open No. 58-99958 has been proposed to solve this problem to some extent. In the air massage device disclosed in this publication, a constriction in the width direction is provided at the center in the longitudinal direction of the air bag, and the center of the air bag is slightly lowered depending on the weight of the user and the like, so that the air bag is inflated. The left and right parts sandwich the body when going out.

However, in this configuration, the central portion of the air bag is slightly sunk due to the weight of the user and the like.
When the air bag was inflated, the left and right portions of the air bag had a small force to pinch the body, and a sufficient kneading effect as obtained by hand could not be obtained.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an air massage device which can provide a sufficient kneading effect as by a human.

And the front and rear ends are open.

The air bladders 23a and 23b correspond to the acupuncture points of the acupuncture points located on the lower limbs of the human body, and the lower airbags 23a and 23b inflate the corresponding lower bladders. By applying it, massage the muscles and stimulate the points.

In FIG. 1, reference numeral 40 denotes an air bag 55a, 55b,
64, 23a, 23b, or air bladders 55a, 5b.
This is an air supply / exhaust device for exhausting the air in 5b, 64, 23a, 23b. The air supply / exhaust device 40 is attached to the rear lower surface of the seat 11.

As shown in FIG. 5, the air supply / exhaust device 40 includes an air compressor 41 for generating compressed air, a filter tank 42 for purifying and storing the compressed air, and a compressed air bag in the filter tank. 55a, 55b, 6
And a control circuit 4 for controlling the air compressor 41 and the distribution switch 43 by operating an operation switch (not shown) on the operation panel 16.
4 is provided.

The distribution switch 43 includes air bags 55a, 55b.
, A hose 46 connected to the air bladders 64, 64, and a hose 47 connected to the air bladders 23a, 23a, 23b, 23b.

The distribution switch 43 supplies compressed air to each of the hoses 45 to 47 to supply each of the air bags 55a, 55b, 64, 23a,
23b is inflated, and the air bags 55a, 55b, 64, 23a, and 23b are exhausted by connecting the hoses 45 to 47 to the outside air. The supply of the compressed air and the communication with the outside air are performed using, for example, a plurality of electromagnetic switching valves.

Next, the operation of the above embodiment will be described.

First, a case where only the neck is massaged will be described.

The main switch (not shown) of the operation panel 16 is turned on. Thereby, the air compressor 41 is driven and the compressed air is stored in the filter tank 42. Then, a neck massage is selected by operating an operation switch (not shown) on the operation panel 16. By this operation, the distribution switch 43 is controlled to supply compressed air to the hose 45, and the air bladders 55a and 55b are inflated as shown in FIG.

The air bags 55a, 55b are in a state in which the opposing side surfaces 52a, 52b of the recess 52 serve as walls, so that the ceiling pillar of the acupoint of the neck is sandwiched and grasped and rubbed.

When the air bags 55a and 55b are fully inflated, the supply of the compressed air to the hose 45 is stopped. Then, compressed air is supplied to the hose 46, and the air bags 64, 64 are inflated. Due to the inflation of the air bladders 64, 64, the movable plate 60 moves backward against the spring. The rearward movement of the movable plate 60 causes the air bladders 55a and 55b to move the air bags 55a and 55b while holding the neck therebetween, as shown in FIG.
It is drawn into.

By this retraction, the air bags 55a, 55b
Means to pull and massage the apex of the acupoint of the neck.

Thereafter, the supply of the compressed air to the hose 46 is stopped, and the hoses 45, 46 are communicated with the outside air to exhaust the air bladders 55a, 55b, 64, 64. This exhaust causes the air bags 55a, 55b, 64, 64 to contract. As the air bladders 64, 64 contract, the movable plate 60 moves forward by the urging force of the spring, and returns to the original state shown in FIG.

By repeating these operations, the neck portion is massaged by grasping and rubbing, and a sufficient pinching and rubbing effect as by manual operation can be obtained.

Next, the case of massaging the calf will be described.

The calf massage is selected by operating the operation switches on the operation panel 16. By this operation,
The distribution switch 43 is controlled to supply compressed air to the hose 47, and the air bladders 23a and 23b are expanded.
Due to the inflation of the air bladders 23a and 23b, the calf of the lower limb is grasped and rubbed so as to be sandwiched from both sides.

When the air bags 23a and 23b are sufficiently inflated, the supply of the compressed air to the hose 47 is stopped, the hose 47 is communicated with the outside air, and the air bags 23a and 23b are evacuated. 23a and 23b contract.

By repeating these operations, the neck is massaged by grasping and rubbing, and a sufficient pinching and rubbing effect can be obtained as by manual operation. By the way, above the holding grooves 22
Side and front and rear ends are open, so the calf
(Legs) can be easily placed in the holding grooves 22, 22.
it can. In addition, the calf is placed in the holding grooves 22,22.
The calf is relaxed by letting it
You can relax this calf
Softens and its calf massages enough
Is done. For this reason, the pinching and rubbing effect as by manual operation is sufficient.
In minutes. In addition, the holding grooves 22
When the air bladders 23a and 23b are inflated,
The holding grooves 22, 22 do not expand at the same time.
The calves by inflating the air bags 23a and 23b.
It can be pressed efficiently from the side, and the pinching and rubbing effect is effective.
It can be obtained efficiently. Moreover, the holding grooves 22, 22
Even when strong, the upper and front and rear ends are open
The calf part can be easily inserted into the holding grooves 22
Can be placed.

In the above embodiment, the neck massage and the calf massage are performed separately, but they may be performed simultaneously. Also, it goes without saying that air bags may be arranged on the seat portion 11 and the backrest portion 14.
Further, the lower limb massage device 20 may have the same configuration as the neck massage unit 50.

According to the first aspect of the present invention, on the concave receiving portion,
And the front and rear ends are open.
Can be easily placed on the concave receiving portion. And concave
Both legs are inflated due to inflation and deflation of the air bag provided on the side of the receiving part.
Pressed or released from the side,
Such a pinching and rubbing effect can be obtained. Moreover, the concave receiving part
It's a leg rest so you can relax
This relaxes the legs and softens them,
The part is fully massaged. For this reason, it is manual
The eel pinching and rubbing effect can be sufficiently obtained. Also,
Even if the concave receiving part is firm, the upper and front and rear ends are open.
So that the legs can be easily placed on the concave
it can. According to the second aspect of the invention, the concave receiving portions are opposed to each other.
The air bladders located on the sides
With this, the massage part of the human body is sandwiched
Therefore, it is possible to obtain a sufficient kneading effect as if by hand.
And pulling the air bag to the bottom of the concave receiving part.
Performing a massaging massage more manually
Can be.
