Abstract

PROBLEM TO BE SOLVED: To make treating elements be laid along the projecting and recessed parts of the body to exhibit a finger pressure effect by communicating the plural treating elements driven to project and sink in with an air bag expanded and contracted with the supply and discharge of air with a common air bag. SOLUTION: When a control device 13 is started, pressurized air of a pressurized air supply source 12 is pressure-regulated by a pressure regulating valve 11 to be supplied and discharged to and from an air bag 7, whereby the air bag 7 is expanded and contracted to operate plural treating elements 3 to project and sink in, thereby applying finger pressure action to the body M. At this time, the projecting and sinking operation of each treating elements 3 is controlled by a controller 14 to obtain a desired treatment mode such as massaging, tapping, or the like. A hollow support frame 4 is installed vertically movably along a pair of right and left fixed rails 5 to change its position in the interior of a backrest part 2, and the respective treating elements 3 are fitted to the front ends of plural support shafts 6 independently supported on the front of the hollow support frame 4 to freely project and sink in. Thus, the treating elements 3 can be independently projected and sunk in to be laid along the projecting and recessed parts of the body M.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage machine configured to drive a treatment element in and out by an air bag which is inflated and contracted by supply and discharge of air.

[0002]

2. Description of the Related Art As the above-mentioned massage machine, for example, as disclosed in Japanese Patent Application Laid-Open No. Sho 57-6655, a push-up plate equipped with a plurality of acupressure members acts on an air bag to inflate and deflate the air bag. There is known a type in which a plurality of acupressure bodies supported by the push-up plate are moved up and down simultaneously by moving the push-up plate up and down.

[0003]

The massage machine having such a structure can perform a massage with a high acupressure effect, but has a structure in which a plurality of acupressure bodies are mounted on a common push-up plate and integrally protrude and disappear. Therefore, in order to make each acupressure body follow the unevenness of the body, the push-up plate as a whole will be inclined, and the operation of each acupressure body will affect each other,
There was a tendency for each acupressure body to be difficult to accurately follow irregularities on the body, or for the pressing force acting on the body to become unbalanced due to a change in the direction of each acupressure body.

[0004] Therefore, an object of the present invention is to provide a massager that can exert acupressure effect satisfactorily by making a plurality of treatment elements conform to unevenness of the body.

[0005]

According to the present invention, as shown in FIG. 2, an air bag 7 which is inflated and deflated by the supply and discharge of air is provided.
In the massage machine configured to drive the treatment elements 3 in and out, the plurality of treatment elements 3 act on the common air bag 7 and each treatment element 3 acting on the air bag 7 operates independently. It is characterized by the following.

[0006] The plurality of treatment elements 3 are independently protruded and retracted along the unevenness of the body, and the air bladder 7 according to the fluctuation of the applied air pressure.
By the expansion and contraction of the body, each part of the body is evenly pressed while each treatment element 3 is maintained in a predetermined posture to perform the acupressure treatment.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment in which the present invention is applied to a chair-type massage machine. Like a general massage machine of this type, a plurality of chairs 1 (in the example, (Four) treatment elements 3 are arranged in parallel, and each treatment element 3 is configured to move in and out by air drive.

As shown in FIG. 2, a hollow support frame 4 is provided inside the backrest 2 so as to be vertically movable and fixed along a pair of left and right fixed rails 5. The four support shafts 6 are independently supported on the front surface of the hollow support frame 4 so as to slide out and retreat, and the treatment element is formed of an elastic material such as rubber having a moderate hardness at the front end of each support shaft 6. 3 is attached.

An air bag 7 made of a rubber material or the like having excellent elasticity is accommodated in the hollow support frame 4. A pressure receiving plate 6 a provided at the inner end of each support shaft 6 faces the air bag 7. At the same time, each support shaft 6 is urged by a spring 8 to slide in the immersion direction.

The air bag 7 has an air inlet / outlet 7a,
The air inlet / outlet 7a is connected to a pressurized air supply source 12 such as a pump or a compressor via an electromagnetically driven control valve 10 and a pressure regulating valve 11, and the operation of these mechanisms is controlled by a controller 13. The armrest 15 of the chair 1 includes a controller 14 connected to the control device 13,
The start and stop of the control device 13 and the operation adjustment thereof can be performed while sitting.

The massage machine according to the present invention is configured as described above. When the control device 13 is activated, the pressure of the pressurized air from the pressurized air supply source 12 is regulated by the pressure regulating valve 11. The air bag 7 is supplied to and discharged from the air bag 7 in a desired characteristic pattern.
Each treatment element 3 is moved in and out with the contraction, and a local acupressure is applied to the body M. At this time, the controller 14 selects and adjusts the amount of protrusion of the treatment element 3, the protrusion pressure, the appearing / retreating speed, the appearing / retreating cycle, and the like, so that a desired treatment mode such as a kneading mode or a hitting mode can be obtained. Further, by adjusting the vertical height of the hollow support frame 4, the treatment location can be changed to a shoulder, a back, a waist, or the like.

In the above example, the treatment element 3 is immersed and urged by the spring 8, but the spring 8 may be omitted and the treatment element 3 may be immersed by the leaning action of the body M on the backrest 2. Good. The air bladder 7 may be configured in a bellows shape.

FIGS. 3 to 5 show examples in which the present invention is applied to a massage machine for upper and lower limbs. In this case, a pair of left and right treatment elements 3 are provided independently at a plurality of locations (three places in the example) in the longitudinal direction of the upper surface of the main body 16 on which the upper limb and the lower limb are to be placed, respectively. The child 3 is driven to protrude and retract by the inflation and contraction of each air bag 7 housed in the main body 16, and the drive control is performed in the same manner as in the previous example.

[0014]

According to the present invention, the plurality of treatment elements 3 which appear and disappear independently are driven by the inflation and contraction of the common air bag 7, so that each treatment element 3 can be operated without changing its working posture. Each of the treatment elements 3 can be uniformly and appropriately exerted with the acupressure function while being able to perform the pressure operation evenly along the unevenness of the body.
