Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for use in home massage, and more particularly to a massage device which provides a physical massage effect by sliding a push ball by air pressure.

[0002]

2. Description of the Related Art In general, a physical massage device using a kneading ball or the like is widely used in current homes. Muscle fatigue due to sports, stiff shoulders, low back pain, etc. may cause the muscle blood vessels around the affected area to contract, resulting in a lack of muscle tone and a prolonged feeling of dullness and fatigue. By physically rubbing,
It has the effect of promoting blood circulation and relaxing muscle tone.

A typical home massage device is a chair-type massage machine, which has a built-in massage mechanism for performing a kneading operation, a hitting operation and the like in a chair-type body. The chair-shaped body is provided with a backrest portion having a built-in massage mechanism, a seat portion continuously provided at a lower end of the backrest portion, a footrest portion extending at a tip of the seat portion, and an upper end of the backrest portion. One formed with a head abutment portion is well known. The backrest portion, the seat portion, the footrest portion, the head contact portion, and the like are rotatably connected so that the angle can be adjusted between them. Then, the massaging ball moves along the back side of the backing material of the backrest portion, performs a finger pressure-like operation by driving a motor or the like, and performs a massage action.

[0004] These motor driven massages are
It is a configuration in which the massaging balls and the like are mechanically rocked back and forth, up and down, etc., and the user deposits weight on the body support means such as the backrest portion, which causes excessive finger pressure-like stimulation and avoids this Therefore, when an excessive load is applied to the kneading balls or the like by the safety device, the operation is stopped.

Therefore, a mechanical massage machine that adjusts the body pressing force without stopping the massage operation has been devised. For example, in Japanese Patent Application Laid-Open No. 7-59825, a pair of left and right treatment elements for performing a massage operation, a mechanism for adjusting the distance between the two treatment elements, and a mechanism for adjusting the strength of the massage operation by both treatment elements are provided. In a pine surge machine, the adjusting operation by these adjusting mechanisms is operable only for the treatment element during the pine surge operation, and the treatment element during the pine surge operation is moved to increase or decrease the strength. A pine-surge machine has been devised that does not over-stretch or narrow the interval to adjust or adjust the interval, and does not apply an excessive load to the user. .

However, in order to prevent an excessive load from being applied to the user in these motor driven massage machines, the above-mentioned Japanese Patent Application Laid-Open No. 7-5982 has been proposed.
Japanese Patent Laid-Open No. 5-3898
The pressing force detecting mechanism shown in the example of Japanese Patent Application Laid-Open No. H11-157572 is required, and it is inevitable that the structure becomes complicated. In order to prevent the structure from becoming complicated and large, a massage machine driven by air pressure has been devised. JP Hei 10
In Japanese Patent Application Laid-Open No. 155854, a mechanism that operates by pneumatic pressure is incorporated in a driving unit for operating a fir ball in a pine surge, and when excessive movement resistance acts on the fir ball, the working air is compressed, so that it is painful. Since the movement of the fir-ball is decelerated or stopped before the user feels, there is no need to adjust the position of the motor and its transmission mechanism, etc., and a massage machine that does not complicate the structure and does not increase the size has been devised. ing.

This has the following configuration as shown in FIG. Four fir balls 3 are protruded from the upper surface of a casing 2 having handles 1 protruding to both sides, and a driving unit 4 for massaging the fir balls 3 is provided inside the casing 2. Have been. Fir ball 3
It is formed of a flexible material with a hollow inside like a rubber ball. Therefore, if gas such as air is taken in and out of the fir balls 3, the fir balls 3 can be switched between a state in which the fir balls 3 are crushed by applying an external pressure and a state in which the swollen shape is held by the internal pressure. The hardness of the expanded state can be changed according to the level of the internal pressure.

The drive section 4 is constituted by an actuator using a gas such as air as an operation source, and has two cylindrical bodies 5 having a bellows structure. These cylinders 5 extend when a gas such as air is supplied to the inside thereof,
Conversely, if gas escapes, it shortens. By actuating the drive unit 4, the support member 6 that repeats swinging
Accordingly, each of the four fir balls 3 moves in a predetermined plane to perform a so-called fir massage operation.

When the fir ball 3 makes excessive contact with the body, the operation of the driving section 4 is decelerated or stopped by the operational resistance, so that it is possible to prevent the fir effect from being too strong and causing pain. You. Each fir ball 3 repeats expansion and contraction in the state of contact with the body,
As a result, a massage operation similar to acupressure or beating is performed. In this case, too, the body is not so painfully pressed or beaten, but is automatically adjusted to an appropriate level. If the internal pressure of the fir balls 3 can be adjusted from this, the hardness of the fir balls 3 can be set to a desired value, which is extremely convenient.

[0010]

However, in the above-mentioned conventional physical massage, it is necessary to promote the blood circulation and to relax the muscle tension by selectively rubbing muscle fibers at the corresponding locations. At this time, it is effective to sequentially press the muscles along the muscle fibers to release the muscle tension. There are massage devices that use pneumatic pressure, in which the treatment element expands and contracts by air pressure, and in which the treatment element is driven using air pressure. The treatment element is mounted on a pneumatic actuator used in a fir ball drive unit. Because it is arranged, the treatment element is separated from the treatment element, and if the treatment element does not hit the appropriate position when sequentially pressing the muscle, it goes without saying that the treatment element has hit the appropriate position. However, there is a problem that the muscles cannot be pressed between the treatment elements, and proper sequential pressing cannot be performed.

In the present invention, in order to solve such a problem, it is possible to selectively knead and muscle the muscle fiber at a position corresponding to the body of the massaged person, and to arrange the fir balls between the treatment elements so as to apply appropriate sequential pressing. The present invention is to provide a massage machine that can provide muscle massage and can effectively relieve muscle tone of a specific part of the body.
