no. 1 example

[0041] The first embodiment ( figure 1 , figure 2 )

[0042] In the massage machine 1, the back rest portion 12 extends obliquely rearwardly and upwardly from the rear end of the seat portion 2 supporting the buttocks of the person to be treated, and the calf placement portion 14 extends obliquely forwardly downwardly at the front end of the seat portion 2 for a short period of time. Armrests 13, 13 are provided on both left and right sides of the seat 2. As shown in FIG.

[0043] Massage machine 1 is reclining chair type, in figure 2 In the reset state shown in a, the seat part 2 is approximately parallel to the ground 7, and figure 2 Under the reclining chair state shown in b, the seat portion 2 is inclined so that the front portion is lifted higher than the rear portion. This inclination angle can be adjusted arbitrarily by the lifting drive mechanism described later.

[0044] Such as figure 1 As shown, a treatment mechanism 15 is respectively equipped on the opp...

[0066] The second embodiment ( image 3 )

[0067] This is an embodiment in which the rail 6 is omitted from the first embodiment described above.

[0068] In the second embodiment, if the floor 7 is tatami or carpet, smooth lifting of the auxiliary legs 3 cannot be expected, but if it is a hard floor such as a wooden floor, there will be no problem in the lifting operation of the auxiliary legs 3 .

no. 3 example

[0069] The third embodiment ( Figure 4 )

[0070] The rail 6 is omitted from the first embodiment described above. Also, the position of the bracket 10 pivotally supporting the auxiliary leg 3 is changed to the rear portion of the seat portion 2 .

[0071] Compared with the first embodiment, the upper end pivot support position of the auxiliary leg 3 is closer to the deflection fulcrum 21 of the seat 2, but the installation position of the airbag 41 is hardly changed compared with the first embodiment.

[0072] The size of the expansion load of the airbag 41 is not affected by the pivotal support position of the auxiliary leg 3, but is mainly affected by the position of the airbag 41 from the deflection fulcrum 21, so in the case of the third embodiment, the expansion of the airbag 41 The load hardly changes from the first embodiment.

[0073] However, as seen from the accompanying drawings, in the reset state of the massage machine 1, the third embodiment is closer to par...

Abstract

The invention provides a massager, when a seat part of the massager is inclined due to the expansion of an air bag, the load is reduced relative to the air bag, and the expandable stroke of the air bag is shortened. In the massager provided with the seat part (2) holding the buttock of a patient, which is inclined by using an oblique fulcrum (21) at the rear side of the seat part to change the angle of the seat part (2), a pivot of an auxiliary leg (3) for inclining the seat part before the oblique fulcrum (21) is supported to be lifted on the seat part (2), and the auxiliary leg is connectedwith the air bag (41).

Description

technical field [0001] The present invention relates to a massage machine capable of changing the inclination of a seat supporting the buttocks of a person to be treated. Background technique [0002] Among massage machines, there is a massage machine that utilizes the expansion and contraction of an air bag to perform massage, that is, a massage chair with an air pump. Therefore, the applicant attempted to change the inclination of the seat by expanding and contracting air cells different from massage air cells using the air pump. [0003] However, it is known that a small air pump for massage cannot adopt a structure in which the seat portion is directly raised by the expansion of the airbag. Such as Figure 12 As shown, when the raised position of the airbag 41a relative to the seat 2 is close to the deflection fulcrum 21 of the seat 2, the load on the airbag becomes large and the torque is insufficient. Therefore, it is necessary to replace the airbag 40 with a large a...
