Full rigidity. In the case of the present embodiment, the seat portion 2 is a housing formed of plastic and is provided The frame bone composed of a metal pipe in the casing is combined and formed.

Moreover, the upper surface of the seat portion 2 is formed on the center side thereof Both ends of the right direction are still low. The center side of the seat portion 2 is formed into a flat surface shape so that a cushioning material or the like can be placed. On the other hand, in the central portion of the flat seat portion 2, the front airbag 5 and the rear airbag 6 are arranged side by side in the front and rear.

Further, the seat portion 2 is formed in a tapered shape in which the sectional area in the horizontal direction becomes smaller and smaller as it goes from the upper side toward the lower side, and the area of the lower surface of the seat portion 2 is larger than the area of the upper surface. Still small. On the lower surface of the seat portion 2 having a small area, a support portion 7 to be described later is provided.

The armrest portion 3 is oriented upward from the upper surface of the seat portion 2 The bulging method is provided on the left and right sides of the seat portion 2, and the elbow of the user U can be placed on the upper end of the bulged portion. The armrest portion 3 has a left armrest portion provided on the left side of the seat portion 2 for supporting the left elbow of the user, and a right armrest portion provided on the right side of the seat portion 2 for supporting the right elbow of the user. The left and right armrest portions 3 and 3 are symmetrical with each other in the center of the center of the seat portion 2, and both of them are respectively housed on the side facing the user U (inward in the width direction) (the left airbag 8 to be described later) And right air bag 9).

As shown in Fig. 5, the backrest portion 4 is behind the seat portion 2. On the side, the member is mounted in such a manner as to stand up and down, and the back of the user U is supported from the rear. On the rear side of the backrest portion 4, an arm member 10 extending downward is provided. The upper end side of the arm member 10 is coupled to the backrest portion 4, and the movable joint member 11 is provided on the lower end side. That is, the backrest portion 4 is made to be movable by the movable joint member 11 and at the rear end side with respect to the seat portion 2 The arm members 10 that are free to swing around the shaft in the left-right direction are coupled, and the lower end is centered to adjust the elevation angle. The inside of the backrest portion 4 is also housed in an airbag (back airbag 12 to be described later) on the side (front side) facing the user U.

By the way, in the above seat 2, the armrest 3, or Inside the back portion 4, there are respectively provided airbags for pressing a part of the body of the user U seated on the seat portion 2. Specifically, in the present embodiment, one for each of the front and rear of the seat portion 2, one for each of the left and right armrest portions 3, and one for the backrest portion 4, and five airbags are provided in total.

Among the above five airbags, the left airbag 8 is housed in the left armrest portion 3, and the left side of the user's U is pushed in the right direction, and the right airbag 9 is housed on the right side of the armrest portion 3. In order to push the right thigh or waist of the user U toward the left. The left airbag 8 and the right airbag 9 are the first airbags that allow the user U to perform the torsional movement in the left-right direction by pressing the lower limbs of the user U in the left-right direction.

Moreover, the front airbag 5 is built in the front side of the seat 2 and will be The user U pushes the upper leg upward, and the rear airbag 6 is built in the rear side of the seat 2 and pushes the user U's buttocks upward. The front airbag 5 and the rear airbag 6 are the second airbags that allow the user U to perform the torsional movement in the front-rear direction by pressing the lower limb or the waist of the user U upward.

Moreover, in the above-described shaping chair 1, except for the first airbag or The second airbag is further provided with a backrest portion 4 and a back edge of the user U The back airbag 12 is pushed in the front and rear direction.

These airbags can be individually swelled by using compressed air or the like that is not displayed on the surface of the pump or the exhaust pipe. Contraction, by bulging the airbag. By contracting, the user's U's thigh, buttocks, back, etc. are pushed in the front-rear direction or the left-right direction.

Furthermore, if the above-mentioned airbag is provided, for example, in the buttocks in the body The so-called easy-to-relax area of the thigh or thigh causes the muscles in the place where it is easy to relax when the airbag is swollen, and the muscles in these places will contract, and the slight shaping movement can be performed.

However, in order to truly strengthen the physical ability and realize or maintain the lean body type, it is not only a superficial muscle that is stimulated by a balloon or the like, but also a so-called deep muscle that exists in the inner muscle or the core muscle existing inside the body.

Here, in the shaping chair 1 of the present invention, in the seat 2 The lower side is provided with a support portion 7 having a curved surface that bulges downward, and the top portion 16 on the curved surface continues to contact the floor surface, and supports the seat portion 2 while maintaining balance with respect to the floor surface.

When the support portion 7 that supports the seat portion 2 while maintaining balance with respect to the floor surface is provided, the user on the seat portion 2 is pressed when any of the airbags is pressed against the user U seated on the seat portion 2 The posture of the U or the seating position changes to make the chair 1 tilt. Since the user U wants to return the inclined chair 1 to the original shape and twist the upper body in the opposite direction to the inclined side, the user can naturally perform the so-called twisting upper body. Effective exercise for deep muscles. As a result, not only the muscles of the surface layer stimulated by the airbag Meat can also exercise deep muscles such as the inner muscles or the core muscles, which can more effectively strengthen the physical ability or maintain the thin body type.

In other words, the chair 1 for shaping of the present invention is not only only The use of an airbag for stimulating a muscle that is easy to relax is also used to push the user U and perform a function of shaping movement for maintaining balance.

Further, when the support portion 7 is provided with the support portion 7 of the present invention, the seat portion 2 is configured to be tiltable, and it is conceivable that the seat 1 is carried by the user U when the seat portion 2 is swung toward the rear. In the state where the state is reversed in the wrong direction, the angle of the tilting prevention portion 13 for preventing the chair 1 from falling over is necessary to prevent the angle generated when the seat portion 2 is tilted toward the rear of the user U to a predetermined inclination or more. Or a component that is missing.

Next, a description will be given of a chair 1 for shaping the same as the present invention. The support portion 7 and the fall prevention portion 13 are characterized.

2 to 4, in particular, as shown in detail in Fig. 5, the support portion 7 is a member having an area which covers the lower surface of the seat portion 2. The support portion 7 has a central portion that is curved so as to protrude downward with respect to the outer edge portion, and the projecting end that protrudes downward is formed into a curved surface that is bent downward in a hemispherical shape.

Further, the support portion 7 is any part of the curved surface of the protruding end (the top portion 16 in the standing state) can be in contact with the floor surface, and the contact portion can support the entire weight applied to the seat portion 2 while maintaining balance. Then, when the seat portion 2 is tilted in any direction with respect to the horizontal plane, the contact portion in contact with the floor surface moves to another position on the curved surface, and Since the position is maintained at the balance of the weight applied to the seat portion 2, the support portion 7 can continue to tilt the seat portion 2 and support the weight applied to the seat portion 2.

Specifically, the top portion 16 of the support portion 7 is located at the seat portion 2 The lower side of the center, in other words, is located on the lower side of the front and rear direction of the seat portion 2 and the left and right direction, and the user U seated on the seat portion 2 can appropriately adjust the seat posture by slightly twisting the upper body or the like. The balance of the weight is easily adjusted by twisting the direction of the upper body. Further, the distance from the lower surface of the seat portion 2 to the upper and lower directions of 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 allows the upper surface of the seat portion 2 to be inclined with respect to the floor surface. A tilting action to a tilt angle of, for example, about 20°.

The tipping prevention portion 13 suppresses the orientation of the chair 1 (seat portion 2) The angle generated when the rear tilting operation is equal to or greater than a predetermined inclination, and the person who is tilted toward the rear in order to prevent the rear tilting operation of the chair 1 from being excessive. In the present embodiment, the fall prevention portion 13 is composed of a pillar member 14 and a protruding piece 15 provided at a lower end of the pillar member 14, and the pillar member 14 is a group of left and right extending downward from the seat portion 2. The tube is formed. The protruding piece 15 is formed by bending a tube into a circular racetrack 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 cushioning material or the like is placed). Further, the front end side of the protruding piece 15 is coupled to the lower end of the strut member 14, and the rear end of the protruding piece 15 is located further rearward than the rear end of the seat portion 2, and the rear of the chair 1 can be prevented by contact with the floor surface or the like. Tilting action.

For example, as shown in Figure 6(a), there is no chair 1 at all. In the case of a tilting action, the upper surface of the seat 2 and the floor surface are substantially mutually Parallel, and the protruding piece 15 of the fall prevention member 13 is also parallel with respect to the floor surface. Therefore, the protruding piece 15 does not contact the floor surface, and the tilting action of the chair 1 is not defined by the tipping prevention member 13.

However, as shown in FIG. 6(b), when the chair 1 is tilted toward the rear, the upper surface of the seat portion 2 is inclined downward toward the floor surface, and is mounted in parallel with the upper surface of the seat portion 2. The protruding piece 15 also becomes inclined with respect to the floor surface. Further, when the chair 1 reaches the predetermined tilt angle tilting operation, the rear end side of the protruding piece 15 comes into contact with the floor surface, and the chair 1 can no longer tilt upward beyond the tilt angle. Therefore, if the fall prevention portion 13 described above is provided, it is possible to prevent the chair 1 from tilting too far toward the rear and tilting.

Second, using Figure 7 (a) ~ Figure 7 (c), said The shaping movement by the shaping chair 1 of the present embodiment will be described. Further, in Figs. 7(a) to 7(c), the chair 1 for shaping is viewed from the front (front) of the chair 1, and the user U seated on the chair 1 (shown in gray in the figure) In addition, in the following description, the left and right airbags 8 and 9 (first airbag) are used to push the user U in the left-right direction by using the left and right airbags 8 and 9 (Example 1). The shaping movement is a representative example.

As shown in Fig. 7(a), the left air bag 8 and the right air bag 9 are shown. In the case where there is no swelling, it is conceivable that the user U is seated on the seat portion 2 while the support portion 7 is held in balance on the floor surface. As shown in Fig. 7(b), when the right airbag 9 is swollen, the waist and the lower limbs of the user U of the right airbag 9 are horizontally pressed toward the left direction, and the user U's The waist and even the lower limbs will move to the left.

At this time, as shown in Figure 7 (c), as long as the user U will When the upper body is twisted in the right direction to maintain balance, the right side of the chair 1 becomes heavier and the inclination toward the left direction is corrected. In other words, the user U exercises deep muscles such as the inner muscle or the core muscle by shaping the upper body with nature. Therefore, according to the above-described chair 1 for shaping, the user U who is seated can effectively perform the shaping movement for the purpose of strengthening the physical ability or maintaining the slim body type.

Moreover, the above shaping movement uses the first airbag. As an example of the torsional movement in the left-right direction, the second airbag can be used to perform the shaping movement in the front-rear direction by the following sequence.

For example, as shown in Fig. 6 (a>, when the chair 1 has no tilting operation 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 above-described fall prevention member 13 is also opposed. The floor surface is parallel. Therefore, the protruding piece 15 does not contact the floor surface, and the tilting action of the chair 1 is not limited by the tipping prevention portion 13.

In this state, if it is provided on the upper surface of the seat portion 2 When the second airbag constituted by the front airbag 5 or the rear airbag 6 is swollen, the lower limb or the waist of the user U can be pressed upward. For example, as shown in Fig. 6(b), if only the compressed air is supplied to the front airbag 5 while the rear airbag 6 is kept in a contracted state, the front airbag 5 is swollen, and the lower limb of the user U remains positioned. The state in which the hips are lowered near the back side is raised near the knee on the front side, and the posture of the user U is tilted toward the rear.

At this time, as long as the user U twists the upper body toward the front, etc. To maintain balance, the front side of the chair 1 becomes heavier and the tilt toward the rear is corrected. In other words, the user U exercises deep muscles such as the inner muscle or the core muscle by the shaping movement toward the front of the upper body with nature.

Further, when the tilting motion toward the rear of the chair 1 is too large, the fall prevention member 13 comes into contact with the floor surface, and the situation in which the chair 1 is further turned backward is eliminated, and the shaping movement can be performed safely.

Moreover, the state in which the front airbag 5 is kept contracted only to the rear airbag 6 When the compressed air is supplied, the user U is displaced toward the front, and the user U can perform the shaping movement accompanying the backward twisting in order to maintain the balance.

Furthermore, the above-mentioned chair 1 can be used as a general chair when the shaping exercise is not performed. That is, the user U is deeply seated in the seat portion 2, and the center of gravity of the chair 1 naturally becomes rearward. The above-mentioned fall prevention member 13 will come into contact with the floor surface, and the chair 1 will be quiet on the floor surface in a stable posture. Set the status.

As described above, the chair 1 for shaping according to the present invention can be made The user U seated performs an effective shaping movement.

Further, all the descriptions of the embodiments disclosed herein are to be considered as illustrative and not restrictive. In particular, in the embodiments disclosed herein, matters that are not clearly disclosed, for example, operating conditions or operating procedures, various parameters, size, weight, volume, etc. of the components, do not exceed the range generally practiced by the industry. It is easy to imagine the value as long as it is a general business.

In the above embodiment, it is assumed that five airbags are provided. For example, as long as the number of airbags is at least one or more, several may be used.

In the above-described embodiment, the airbag is arranged side by side in front of and behind the seat portion, but the airbags on the seat portion may be arranged side by side.
