It should be noted that the guide rail may be extended to the rear portion of the seat portion 2 so that the massage unit moves up and down within the seat portion 2 and the backrest portion 3 .

An upper arm airbag AB2 is provided at the upper left end and the upper right end of the backrest portion 3 . The user's upper arm is treated by the expansion and contraction of the upper arm airbag AB2.

The base portion 4 is a metal frame provided below the seat portion 2 and supports the seat portion 2 . Inside the base 4, a backrest actuator (not shown in FIG. 1), an ottoman actuator (not shown in FIG. 1), and a control unit CU1 are provided. The control unit CU1 controls various motors, various airbags, and the like based on signals output from an operation unit (not shown).

The forearm treatment sections 5 are provided upright on both the left and right sides of the seat section 2 and above the seat section 2 . The forearm treatment section 5 is provided with a forearm airbag (not shown). The forearm of the user is treated by inflating and deflating the forearm airbag.

The ottoman 6 accommodates the lower legs of the user. The ottoman 6 is provided with a leg airbag AB3. The user's lower legs are treated by inflating and deflating the lower leg airbag AB3.

The ottoman 6 is attached to the massage machine main body so as to be rotatable around a first rotation axis AX1 extending in the left-right direction. Specifically, the ottoman 6 is attached to the front end of the upper portion of the base portion 4 so as to be rotatable around a first rotation axis AX1 extending in the left-right direction.

The control unit CU1 varies the positional relationship of the ottoman 6 with respect to the main body of the massage machine based on the signal output from the operating section. As the positional relationship of the ottoman 6 with respect to the main body of the massage machine that can be realized by the control of the control unit CU1, there are the positional relationships shown in FIGS. 2 to 4, for example. 2 to 4, illustration of the side cover of the massage machine 1 and the like is omitted.

In the positional relationship shown in FIG. 2, when the user is seated on the massage machine 1 and the lower legs of the user are accommodated in the ottoman 6, the ankles of the user are positioned substantially directly below the knees of the user.

The positional relationship shown in FIG. 2 can be changed to the positional relationship shown in FIG. can. In the positional relationship shown in FIG. 3, when the user is seated on the massage machine 1 and the lower legs of the user are housed in the ottoman 6, the ankles of the user are located forward of the knees of the user.

By rotating the ottoman 6 counterclockwise as viewed from the left side of the massage machine 1, that is, by rotating the ottoman 6 from the front to the rear, the positional relationship shown in FIG. 3 can be returned to the positional relationship shown in FIG. can. However, as shown in FIG. 3, a foreign object 10 may be caught between the back surface of the ottoman 6 and the front surface of the base portion 4 .

In the massage machine 1, in a state where a foreign object 10 is sandwiched between the back surface of the ottoman 6 and the front surface of the base portion 4 as shown in FIG. is further rotated counterclockwise, the support member 8 rotates clockwise when viewed from the left side of the massage machine 1 as shown in FIG. It is possible to prevent an increase in the force of pinching the foreign object 10 between the front surfaces. As a result, damage to the foreign matter 10 can be reduced without causing a significant cost increase or secondary damage.

FIG. 5 is a left side view of the ottoman actuator 7. FIG. The ottoman actuator 7 has a rod member 71 , a tubular member 72 that accommodates the rear portion of the rod member 71 , and an ottoman motor 73 . A front end 711 of the rod member 71 is rotatably connected to a connecting portion 61 provided on the back surface of the ottoman 6 as shown in FIG.

The ottoman actuator 7 can change the amount of protrusion of the rod member 71 from the cylindrical member 72 by rotating the ottoman motor 73 . As the amount of protrusion of the rod member 71 from the cylindrical member 72 increases, the ottoman 6 rotates clockwise when viewed from the left side of the massage machine 1 . Conversely, when the amount of protrusion of the rod member 71 from the tubular member 72 decreases, the ottoman 6 rotates counterclockwise when viewed from the left side of the massage machine 1 .

However, even if the amount of protrusion of the rod member 71 from the cylindrical member 72 is reduced, the ottoman 6 rotates by the amount that the support member 8 rotates clockwise when viewed from the left side of the massage machine 1 as shown in FIG. is suppressed.

FIG. 7 is a left side view of the ottoman actuator 7 and the support member 8. FIG. Part of the base 4 is also shown in FIG. The base portion 4 supports the support member 8 , and the support member 8 supports the ottoman actuator 7 .

The support member 8 is rotatable relative to the base 4 around a second rotation axis AX2 extending in the left-right direction, and is cylindrically shaped around a third rotation axis AX3 extending in the left-right direction. It is rotatable with respect to member 72 .

The positional relationship between the first rotation axis AX1 and the seat portion 2 is fixed, and the positional relationship between the second rotation axis AX2 and the seat portion 2 is fixed. The first rotation axis AX1 is positioned forward and above the second rotation axis AX2. The positional relationship between the third rotation axis AX3 and the seat portion 2 changes as the support member 8 rotates around the second rotation axis AX2. Specifically, when the support member 8 rotates clockwise about the second rotation axis AX2 when viewed from the left side of the massage machine 1, the third rotation axis AX3 moves forward with the seat 2 as a reference. As a result, even when the amount of protrusion of the rod member 71 from the cylindrical member 72 is reduced as described above, the rotation of the ottoman 6 is suppressed.

The third rotation axis AX3 is preferably provided at the rear end of the tubular member 72 of the ottoman actuator 7 . This is because the support member 8 rotates smoothly.

In addition, it is preferable to provide an elastic member 9 that biases the support member 9 so that the third rotation axis AX3 faces rearward. This is because the support member 9 can be smoothly returned to its original position when the force for directing the tubular member 72 of the ottoman actuator 7 toward the front is no longer applied to the tubular member 72 .

One end 91 of the elastic member 9 is preferably attached to the support member 8 at a position between the second rotation axis AX2 and the third rotation axis AX3. This is because the biasing force of the elastic member 9 can be adjusted not only by the elasticity of the elastic member 9 but also by the mounting position between the second rotating shaft AX2 and the third rotating shaft AX3. The other end 92 of the elastic member 9 is attached to the base portion 4 .

The above embodiments should be considered illustrative in all respects and not restrictive, and the technical scope of the present invention is indicated by the scope of claims rather than the description of the above embodiments. It should be understood that all modifications that fall within the meaning and range of equivalents of the claims are included.

For example, in the above-described embodiment, the ottoman actuator 7 is suspended by the support member 8, but the ottoman actuator 7 is supported by reversing the positional relationship between the ottoman actuator 7 and the support member 8 in the vertical direction. A structure that is lifted by the member 8 may be used. However, the structure in which the ottoman actuator 7 is suspended by the support member 8 is preferable because the member (part of the base portion 4) that supports the support member 8 can be easily arranged.

Further, for example, in the above-described embodiment, the seat portion 2 is fixed to the base portion 4, but the base portion 4 is configured by the base portion body and the base portion for the seat portion. The portion 2 may be fixed to the seat portion base portion, and the seat portion base portion may be slidable in the front-rear direction with respect to the base portion main body. In this case, for example, if the ottoman 6 is attached to the seat base rotatably around the first rotation axis AX1, and the support member 8 is attached to the seat base rotatably around the second rotation axis AX2, good. As a result, even if the seat portion base portion is slid in the front-rear direction with respect to the base portion main body, the positional relationship between the first rotation axis AX1 and the seat portion 2 can be fixed, and the second rotation axis AX2 can be fixed. and the seat portion 2 can be fixed.
