As shown in FIG. 1, it is a perspective view which shows the external appearance of a chair type air massage machine. The chair body 11 is provided with a seat portion 12 substantially horizontally above the installation surface of the air massage machine, a back portion 13 is provided at a predetermined angle on the rear side of the seat portion 12, and provided on both sides of the seat portion 12. The armrest part 14 is comprised.
[0014]
The seat portion 12 and the back portion 13 are provided with waist airbags 15a, 15b, 15c, a back airbag 16, and a head airbag 17, which are airtight and made of a soft material. Each air bag is connected to an air drive unit 19 provided under the seat 12 by a piping hose 18 made of an elastic member. The air bag is inflated and deflated by supplying air distributed to each air bag by pneumatic expression means including a pump (not shown) built in the air drive unit 19 and air passage opening / closing means.
[0015]
The armrest portion 14 is provided with an adjusting means 20 capable of adjusting air supply / exhaust on one side of both sides. For example, by operating the waist airbag adjustment means 20a, 20b, 20c, the back airbag adjustment means 20d, and the head airbag adjustment means 20e, the piping hose 18 is pressed or tightened by a pressing means (not shown). The air in each air bag is adjusted.
[0016]
As shown in FIG. 2, the pressing means 21 provided on the outer periphery of the pipe hose 18 made of an elastic member connected to the waist central airbag 15 b and the air drive unit 19 is composed of a fixed member 22 and a movable member 23. Has been. The movable member 23 that faces the hose holding member 22 that is the fixing member via a hose has a pressing tool 24 and a coil spring 25 that is an elastic member interposed between the elastic member fixing surface 26.
[0017]
Usually, the piping hose 18 is deformed by the force of the coil spring 25, which is an elastic member, so that the sectional area of the piping hose 18 is reduced. Along with this, the air inflow amount of the airbag is suppressed, and the inflation speed of the airbag is decreased. When the deformation of the hose 18 by the elastic member 25 made of a coil spring recovers as the internal pressure increases as the amount of air in the airbag increases, the timing at which the airbag inflates can be delayed. Among the plurality of airbags, the inflation timing of the airbag can be shifted by changing the deformation of the hose depending on the portion where the force of the elastic member 25 is increased by the adjusting means 20 and the portion where the force is reduced.
[0018]
Further, as shown in FIG. 3, the portion that abuts on each inner hose of the pressing member 24 that is a part of the movable member 23 and the hose holding member 22 that is a fixed member is shaped along the outer shape of the hose When the pressing tool 24 and the hose holding member 22 are applied to the hose 18 in the direction in which the hose 18 is deformed by the elastic member 25, the effect of uniform deformation of the hose can be obtained.
