Description

Massage machine

  The present invention relates to a massage machine that performs massage with an air bag that expands and contracts with respect to a human body sitting or sleeping.

As shown in FIG. 3 , the thigh massage air bladder 2 is arranged on the front end side of the chair seat 6 and the buttocks massage air bladder 3 is arranged on the rear end side of the seat 6, and further the seat. There is a massage machine in which an air bag 1 for massaging a calf is disposed on a leg stand 4 that is rotatably attached to the front end of the part 6. The air bags 1, 2, and 3 connected to the air supply / exhaust means compress and massage the human body due to the expansion thereof. In the illustrated example, an air bag 11 is also disposed on the backrest 8 so that a pressure massage can be performed on the back and waist of the human body.

  By the way, the air bag 1 provided on the leg platform 4 presses the calf portion so as to sandwich the calf portion from both sides, while the thigh air bag 2 and the buttocks air bag 3 are large due to their expansion. The thigh and buttocks are pushed up from below, so that the human body floats upward, and the massage force generated by the inflation of the air bags 2 and 3 cannot be used effectively.

In addition, the air bags 2 and 3 are formed long in the direction perpendicular to the longitudinal direction of the human body, and may have a shape that blocks the blood flow when inflated. It was something that could not be done.

This invention is invented in view of said conventional problem, Comprising: It exists in providing the massage machine which can utilize effectively the massage force by expansion | swelling of an air bag.

In order to solve the above problems, a massage machine according to the present invention includes air bags for pressing a portion from the thigh to the buttocks of the human body from both sides, and the air bag that is inflated and contracted by the air supply / exhaust means. It is characterized in that a backup plate is arranged on the outer surface . In addition to widening the part that can be massaged by pressing the human body, it can prevent the human body from lifting when the air bag that presses the part from the thigh to the buttocks from below is inflated, The transmission efficiency of the massage force due to the expansion of the other air bag can be increased.

At this time, it has an air bag that presses a portion from the lower part of the human body to the buttocks from below, and the air bag and an air bag that presses the part from the thigh to the buttocks from both sides simultaneously, or When the air supply / exhaust timing by the air supply / exhaust means is set so that the latter expands slightly faster, the massage effect can be further enhanced.

  Moreover, it is also preferable to make the air bag which presses the part from the thigh of the human body to the buttocks from below into a shape along the longitudinal direction of the human body. Since the air bag does not hinder the blood flow, the massage effect can be enhanced.

The present invention can prevent the portion of the human body from the thigh to the buttocks from being lifted, and can increase the transmission efficiency of the massage force due to the expansion of another air bag. In addition, since there is a backup plate on the outer surface of the air bag that presses the part from the thigh to the buttocks from both sides, the air bag effectively performs the above-mentioned pressing when the air bag is inflated. Compared to the case where there is no air bag, since the air bag can be kept upright, the overall width can be reduced.

Hereinafter, the present invention will be described in detail based on an example of the embodiment . The massage machine shown in FIGS. 1 and 2 includes a seat portion 6, a backrest 8 that can be reclined, and a frame 7 that also serves as an armrest. It is a chair type, and the backrest 8 has a built-in massage mechanism M for performing shiatsu massage. Further, a leg rest 4 is disposed in front of the seat portion 6. The leg mount 4 is attached to the chair frame 7 via an expansion / contraction mechanism 5 that is a lazy tong mechanism, and is retracted below the seat 6 by contracting the expansion / contraction mechanism 5 when not in use. Be able to.

The seat portion 6 is provided with two air bags 3 and 3, and air bags 30 and 30 are provided on both sides of the two air bags 3 and 3. Are provided with air bags 1a and 1b for massage at the calf. Each air bag is connected to an air supply / exhaust means (not shown) and individually inflated by the air supplied from the air supply / exhaust means.

Here, the air bags 1a and 1b provided on the leg platform 4 are U-shaped in section by being suspended from the frame of the leg platform 1, and the calf portion is placed in the concave groove portion. When the air bag 1 is inflated, the calf portion is pressed from the left and right.

Further, the two air bags 3, 3 arranged on the seat 6, which is pressed from below when inflated in contact with the human thigh portion ranging buttocks air bag 30, 30 at the time of inflation Although the human thigh is to press the portion extending buttock from both sides, the outer surface of the air bladder 30, 30 Yes by arranging a backup plate 31 made of hard synthetic resin or the like, the air bag 30 , 30 are set to supply / exhaust timing so as to expand at the same time as the air bags 3, 3 or slightly earlier. C in FIG. 2 is an operating device.

  When the air bag 3 is inflated to press the thigh and buttocks from below, the air bag 30 prevents the thigh and buttocks from floating by pressing the thigh and buttocks from the side. Therefore, the massage force due to the expansion of the air bag 3 acts on the human body more effectively, and the air bag 30 pressing the thigh and the buttocks from the side causes the action of the massage on the human body. It would also be a wider range.

Furthermore, the two air bags 1a and 1b provided on the leg mount 4 are not inflated at the same time, but the air bag 1a located on the distal side is inflated first, and then the air bag 1b is inflated. In addition, intravenous blood in the calf can be sent in the direction toward the heart.

It is a perspective view which shows the external appearance of an example of embodiment of this invention. It is a perspective view which shows an internal structure same as the above. It is a perspective view of a prior art example .
