As shown in FIG. 5, the backrest portion 4 is a member attached to the rear side of the seat portion 2 so as to stand up and down, and can support the back portion of the user U from the rear. ing. An arm member 10 that extends downward is provided on the back side of the backrest portion 4. An upper end side of the arm member 10 is connected to the backrest portion 4, and a hinge member 11 is provided on the lower end side. That is, the backrest part 4 is connected to the arm member 10 so as to be swingable around an axis facing the left-right direction with respect to the rear end side of the seat part 2 by the hinge member 11 so that the reclining part can be reclining back and forth around the lower end. It has become. An airbag (a back airbag 12 to be described later) is also built in the backrest portion 4 on the side facing the user U (front side).

By the way, the airbag which presses a part of user's U body seated on the seat part 2 is each provided in the inside of the seat part 2, the armrest part 3, or the backrest part 4 mentioned above. Specifically, in this embodiment, a total of five airbags are provided, one on each side of the seat 2, one on each of the left and

right armrests

3 and 3, and one on the backrest 4. Yes.
Of the five airbags described above, the left airbag 8 is built in the left armrest 3 and presses the left thigh and waist of the user U in the right direction. Is built in the right armrest 3 and presses the right thigh and waist of the user U toward the left. The left airbag 8 and the right airbag 9 press the lower limbs of the user U along the left-right direction, thereby causing the user U to perform a twisting motion along the left-right direction; It has become.

The front airbag 5 is built in the front side of the seat portion 2 and presses the user's U thigh upward. The rear airbag 6 is built in and used on the rear side of the seat portion 2. The person U's buttocks are pressed upward. The front airbag 5 and the rear airbag 6 are configured to cause the user U to perform a twisting motion along the front-rear direction by pressing the lower limbs and lower back of the user U upward. It has become.

In addition to the first airbag and the second airbag, the shape-up chair 1 includes a back air that is built in the backrest 4 and presses the back of the user U along the front-rear direction. A bag 12 is provided.
These airbags can be individually inflated and deflated by sending compressed air or the like using a pump or an air pipe (not shown), and the user's U thigh can be inflated and deflated. , Buttocks, back, etc. can be pressed along the front-rear direction and the left-right direction.

By the way, if the airbag described above is provided in a place where slack is likely to occur, such as the buttocks and thighs in the body, muscles in places where slack is likely to occur when the airbag is inflated are stimulated. The muscles contract and perform a slight shape-up exercise.
However, in order to fully enhance the ability of the body and realize and maintain the body type, not only the muscles of the surface layer stimulated by airbags, but also deep muscles such as inner muscles and core muscles existing inside the body It is necessary to train.

Therefore, the shape-up chair 1 of the present invention has a curved surface that swells downward on the lower side of the seat portion 2 and is in contact with the floor surface at the top portion 16 on the curved surface with respect to the floor surface. A support portion 7 that supports the seat portion 2 while providing a balance is provided.
Thus, if the support part 7 which supports the seat part 2 is provided, maintaining the balance with respect to a floor surface, when pressing the user U seated on the seat part 2 using either of the airbags mentioned above, The chair 1 tilts as the seating posture or seating position of the user U on the seat 2 changes, and the user U twists the upper body in the opposite direction to try to return the tilted chair 1 to the original position. Thus, it is possible to allow the user to naturally perform a twisting exercise that is effective in training the deep muscles, ie, twisting the upper body. As a result, it is possible to train not only superficial muscles that are stimulated by airbags, but also deep muscles such as inner muscles and core muscles, and more effectively strengthen the physical ability and maintain the body shape. Can do.

In other words, the shape-up chair 1 of the present invention does not use an air bag only for the function of stimulating muscles in a place where it is easy to sag, but performs a shape-up exercise for maintaining balance by pressing the user U. An air bag is used for the function to be performed.
In addition, if the support part 7 is provided like the chair 1 for shape-up of this invention, and the seat part 2 can be tilted, if the seat part 2 swings back too much, the chair 1 will mount the user U. Since the case of accidentally falling backward is also conceivable, the fall preventing unit 13 that prevents the chair 1 from falling by suppressing the seat 2 from tilting more than a predetermined angle toward the rear of the user U is provided. It is provided as an indispensable component.

Next, the support part 7 and the fall prevention part 13 which are the characteristics of the chair 1 for shape-up of this invention are demonstrated.
As shown in detail in FIGS. 2 to 4, particularly FIG. 5, the support portion 7 is a member having an area that can cover the lower surface of the seat portion 2. The support portion 7 is curved so that the center portion protrudes downward with respect to the outer edge portion, and the protruding end protruding downward is formed as a curved surface curved in a hemispherical shape downward. ing.

Further, the support portion 7 can come into contact with the floor surface at any portion (the top portion 16 in the stationary state) on the curved surface of the tip, and is added to the seat portion 2 while balancing at the contact portion. All weights can be supported. When the seat 2 tilts in any direction with respect to the horizontal plane, the contact portion in contact with the floor moves to another position on the curved surface, and the weight applied to the seat 2 at another position Therefore, the support portion 7 can support the weight applied to the seat portion 2 while allowing the seat portion 2 to tilt.

Specifically, the top portion 16 of the support portion 7 is positioned substantially at the center lower side of the seat portion 2, in other words, substantially at the middle lower side in the front-back direction and the left-right direction of the seat portion 2, and is seated on the seat portion 2. If the user U appropriately adjusts the sitting posture by slightly twisting the upper body, the weight balance can be easily adjusted in the direction in which the upper body is twisted. Further, the vertical distance from the lower surface of the seat portion 2 to the top portion 16 of the support portion 7 is about half of the thickness of the seat portion 2, and the support portion 7 has an upper surface of the seat portion 2 with respect to the floor surface. For example, tilting to an inclination angle of about 20 ° can be permitted.

The fall prevention unit 13 suppresses the chair 1 (seat part 2) from tilting rearward by a predetermined tilt angle or more, and prevents the chair 1 from tilting backward due to excessive rear tilt. To do. In the present embodiment, the fall prevention portion 13 is composed of a column member 14 made of a pair of left and right pipe members extending downward from the seat portion 2 and a protruding piece 15 provided at the lower end of the column member 14. ing. The projecting piece 15 has a shape that is obtained by bending the pipe material into a race track shape (rectangular shape) so as to be substantially parallel to the upper surface of the seat portion 2 (a flat surface on which the above-described cushion material or the like is placed). Is formed. And the front end side of this protrusion piece 15 is connected with the lower end of the support | pillar member 14, and the rear end of the protrusion piece 15 is located further back than the rear end of the seat part 2, and contacts a floor surface etc. By doing so, the chair 1 can be prevented from tilting backward.

For example, as shown in FIG. 6A, when the chair 1 is not tilted at all, the upper surface of the seat portion 2 and the floor surface are substantially parallel to each other, and the protruding piece 15 of the fall prevention member 13 is also a floor. Parallel to the surface. Therefore, the protruding piece 15 does not contact the floor surface, and the tilting of the chair 1 is not restricted by the fall prevention member 13.
However, as shown in FIG. 6B, when the chair 1 tilts backward, the upper surface of the seat 2 tilts backward with respect to the floor surface and is parallel to the upper surface of the seat 2. The protruding piece 15 attached so as to become inclined with respect to the floor surface. When the chair 1 tilts to a predetermined tilt angle, the rear end side of the protruding piece 15 comes into contact with the floor surface, and the chair 1 cannot tilt backward beyond this tilt angle. Therefore, if the fall prevention part 13 mentioned above is provided, it will be prevented that the chair 1 tilts too much backward and falls.

Next, the shape-up exercise performed using the shape-up chair 1 of the present embodiment will be described with reference to FIGS. 7 (a) to 7 (c).
7 (a) to 7 (c) show the chair 1 for shape-up and the user U (shown in gray in the figure) sitting on the chair 1 as seen from the front (front) of the chair 1. It shows what shape-up exercise the user U is doing. Further, in the following description, a shape-up exercise performed by pressing the user U along the left-right direction using the left and right airbags 8, 9 (first airbag) is given as a representative example. .

As shown in FIG. 7A, when neither the left airbag 8 nor the right airbag 9 is inflated, the user U sits on the seat portion 2 while maintaining the balance on the floor surface via the support portion 7. Think if you are.
As shown in FIG. 7B, when the right airbag 9 is inflated, the user's U waist or lower limb is pressed horizontally toward the left by the right airbag 9, and the user U's waist or The lower limb moves to the left side of the seat.

At this time, as shown in FIG. 7 (c), if the user U balances by twisting the upper body in the right direction, the right side of the chair 1 becomes heavy and the leftward inclination is corrected. And deep muscles, such as an inner muscle and a core muscle, are trained by the shape-up exercise | movement accompanied by the twist of the upper body which this user U performs naturally. Therefore, according to the above-described chair 1 for shape-up, it is possible to make the seated user U effectively perform shape-up exercises for the purpose of enhancing the ability of the body or maintaining the body type.

The shape-up exercise described above is an example of a twisting exercise along the left-right direction using the first airbag, but the shape-up exercise is performed in the front-rear direction using the second airbag according to the following procedure. You can also exercise.
For example, as shown in FIG. 6A, when the chair 1 is not tilted at all, the upper surface and the floor surface of the seat portion 2 are substantially parallel to each other, and the protruding piece 15 of the fall prevention member 13 described above is also used. Parallel to the floor. Therefore, the protruding piece 15 does not come into contact with the floor surface, and the tilting of the chair 1 is not restricted by the fall prevention unit 13.

In this state, when the second airbag composed of the front airbag 5 or the rear airbag 6 provided on the upper surface of the seat portion 2 is inflated, the lower limbs or waist of the user U can be pressed upward. . For example, as shown in FIG. 6B, when compressed air is sent only to the front airbag 5 while the rear airbag 6 is deflated and the front airbag 5 is inflated, While the vicinity of the buttocks positioned on the rear side is lowered, the vicinity of the knee positioned on the front side is lifted, and the posture of the user U falls backward.

At this time, if the user U balances by twisting the upper body forward, the front side of the chair 1 becomes heavy and the backward tilt is corrected. And deep muscles, such as an inner muscle and a core muscle, are trained by the shape-up exercise | movement with the twist to the front of the upper body which this user U performs naturally.
If the chair 1 is tilted backwards too much, the fall-preventing member 13 contacts the floor, and the chair 1 will not fall back any further, so that the shape-up exercise can be performed safely. .

Also, if compressed air is sent only to the rear airbag 6 while the front airbag 5 is deflated, the user U is displaced forward, and the user U is shaped up with a rearward twist to compensate for it. It is also possible to exercise.
By the way, the chair 1 mentioned above can be used as a normal chair, when shape-up exercise is not performed. That is, if the user U sits deeply on the seat 2, the weight balance of the chair 1 is naturally rearward, and the above-described fall prevention member 13 comes into contact with the floor, so that the chair 1 is in a stable posture. It will be in the state left still on the floor.

As described above, according to the shape-up chair 1 of the present invention, it is possible to cause the seated user U to perform an effective shape-up exercise.
The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. In particular, in the embodiment disclosed this time, matters that are not explicitly disclosed, such as operating conditions and operating procedures, various parameters, dimensions, weights, volumes, and the like of a component deviate from a range that is normally performed by those skilled in the art.
