However, in the above-described exercise aid, it is not easy to cause the main body portion to be largely inclined, and there is a problem in that, for example, when the rotational movement of the waist is performed, the radius of rotation of the waist portion is reduced, and the effective movement cannot be performed. Further, in the case of using the exercise aid described above, the user needs to lower the waist portion to the vicinity of the ground contact surface, and has an unnecessary load on the user's waist or the like.

Further, in Patent Document 1, a method of placing a exercise aid on a table is proposed. In this case, although the load is reduced when the user lowers the waist, it is necessary to prepare a table on which the exercise aid is placed, which is problematic for the user to use. Moreover, even if the exercise aid is used on the stage, it is not easy to tilt the main body portion as described above, and therefore it is difficult to solve the problem that the effective exercise cannot be performed.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a exercise aid which can improve the effect of the movement of the waist and is easy to use.

One aspect of the present invention is a sports aid characterized by comprising a body portion provided with a seat surface on which a user sits and a bottom surface having a slightly spherical shape.

The main body portion has a side portion that is erected and has a pair of flexible sides that are placed on the side of the pelvis portion of the user seated on the seat surface. The side edge portion is formed so as to be able to push the pelvic portion of the user sitting on the seat surface from the side (application 1).

In the above exercise aid, the height of the lowest point of the seat surface falls within the above specified range, and the bottom surface is slightly spherical. Therefore, when the user is seated, the waist is moved by using the grounded foot as a base point, and the bottom surface can be maintained at the ground. In the state, the seat surface is inclined in all directions. Further, since the exercise aid has the seat height of the above-described specific range, the range of movement of the seat surface accompanying the inclination of the seat surface can be ensured to be large within an appropriate range. That is, it is possible to increase the movable range of the user's waist. Therefore, for example, the radius of rotation in the rotational motion of the waist is increased, and the muscles of the waist can be effectively subjected to the torsional motion.

Further, the exercise aid has a restriction means for suppressing a case where the buttocks of the user are displaced from the seat surface. Thereby, the user is less likely to hold the hand support on the exercise aid while exercising. Further, by the above-described range of the specific seat height and the above-described restriction means, the effect of complementing the two can sufficiently improve the movement effect of the waist.

Further, since the height of the seat surface is set within the above-described specific range, the burden when the user sits down is reduced. Therefore, it is easy for the user to be a user.

As described above, according to the above aspect, it is possible to provide a exercise aid that can perform effective exercise and is easy to use.

In the above exercise aid, the height of the seat surface may be such that the ground surface is grounded by placing the center of the seat surface vertically above the ground point. The reference is obtained by measuring the height of the lowest point of the seat surface, and the like. This is the same as when the user sits down on the seat and sets the back in a straight natural state. The height from the ground plane up to the lowest point of the user's buttocks is substantially the same.

The height (lowest point) of the seat surface is 100 mm or more and 450 mm or less. By setting the height of the seat surface within the specific range, it is easy to achieve a state in which the waist of the user is appropriately separated from the ground contact surface. As a result, as described above, the seated surface can be easily tilted by causing the seated user to ground the foot and move the waist. Further, the movable range of the waist of the user is also widened, and the rotational movement can be performed freely. Therefore, it is an effect that can enhance the movement of the waist. Moreover, by making the height of the seat surface appropriate, it is easy for the user to sit down.

When the height of the seat surface is less than 100 mm, not only is it difficult for the user to sit down, but also because the distance between the seat surface and the ground plane is excessively short, the movable range of the waist of the user is narrowed. The effect of exercise is not sufficient. Therefore, the height of the seat surface is set to 100 mm or more, and preferably 140 mm or more, more preferably 160 mm or more.

Further, when the height of the seat surface exceeds 450 mm, the waist of the user is excessively separated from the ground contact surface, and the center of gravity is increased. When the waist portion is moved, it is difficult to achieve balance. Therefore, it is difficult to perform a smooth waist movement, and there is a possibility that the effect of the waist movement is insufficient. Therefore, the height of the seat surface is set to 450 mm or less, preferably 350 mm or less, more preferably 300 mm or less, and still more preferably 200 mm or less. Therefore, from From the viewpoints of both the movable range of the user's waist and the ease of balance, it is particularly preferable that the height of the seat surface is 160 mm or more and 200 mm or less.

The main body portion is formed by a material that does not substantially deform the bottom surface when the user sits down on the seat surface. Thereby, the height of the seat surface can be stably maintained, and the tilting operation using the shape of the bottom surface portion can be smoothly performed.

Further, the shape of the main body portion may be such that it does not interfere with the tilting operation of the seat surface. For example, it is considered that the entire surface is formed by a smooth curved surface continuous with the bottom surface. The shape is a slightly hemispherical shape, or a shape in which one of the rectangular parallelepipeds is formed into a substantially spherical shape and a shape of the bottom surface. In this manner, the shape of the remaining portion of the main body portion is not particularly limited as long as the bottom surface of the substantially spherical shape is formed.

Here, the so-called slightly spherical shape describing the shape of the bottom surface is not limited to a geometrically defined complete spherical surface, but is a concept including a spherical shape as a general feeling. In other words, the bottom surface may have a portion having a curvature that is different as long as the above-described tilting operation in the entire direction can be smoothly performed. For example, the bottom surface may not have the same radius of curvature, but may have a radius of curvature that decreases toward the edge direction or is not rotationally symmetric with respect to the central axis. The radius of curvature in the direction orthogonal to each other is set to a different value or the like.

Further, as the above restriction means, various forms can be employed. As The simplest form has a method in which the surface of the seat surface is made of a material having a high friction coefficient, and the frictional force is used to suppress the deviation between the buttocks and the seat surface of the user.

In another aspect of the limiting means, the shape may be changed such that at least a part of the shape of the hip, the waist or the thigh of the user sitting down is provided on the seat surface or the periphery thereof. Shape change section (application 2).

Thereby, it is possible to form a shape support for the buttocks, the waist or the thigh, and to suppress the deviation between the buttocks and the seat surface of the user.

In still another aspect of the above-described restriction means, a material which is deformed so as to easily follow the shape of the buttocks or the thigh of the user, for example, a low resilience foam or the like is used as the seat portion, and The manner in which the offset between the buttocks and the seat surface is improved is suppressed. These forms can also be combined.

Further, as the restriction means, a pair of sides that stand up between the seat surface and the seat surface may be disposed at a position on the side of the pelvic portion of the user sitting on the seat surface. Edge (application 3).

In this case, the side of the pair of sides is prevented from being displaced from the seat surface by the user's buttocks, and the movement of the pelvis portion of the user is easy to follow the movement of the seat surface. Thereby, for example, when the rotational movement of the waist is performed, it is easier to add the angle between the pelvic portion and the waist, and the muscles of the waist can be more effectively twisted. Therefore, it is an effect that can enhance the exercise more.

Further, the side edge portion may be provided with flexibility. Further, it is formed so as to be able to push the pelvic portion of the user sitting on the seat surface from the side (application 4).

In this case, the pelvic portion of the user can be held by the pair of side edges. Therefore, a sense of unity is generated between the pelvic portion of the user and the seat surface, and the movement of the pelvic portion becomes a movement that more easily follows the seat surface. As a result, the torsional movement of the muscles of the user's waist can be performed more efficiently, and the effect of the exercise can be further improved.

Further, it is preferable that the side edge portion is configured such that the height from the lowest point of the seat surface to the highest point of the side edge portion falls within a range of 100 to 250 mm (application) Item 5).

When the height of the side edge portion described above falls within the above-described specific range, the effect of sufficiently maintaining the pelvic portion of the user can be easily achieved at the same time, and the rotational movement of the waist portion is not hindered. The effect of smooth movement is achieved by the ground. Therefore, the system can enhance the effect of exercise.

When the height of the side edge portion described above is less than 100 mm, there is a problem that the effect of holding the pelvis of the user is reduced. Therefore, the height of the side edge portion is preferably 100 mm or more, more preferably 120 mm or more, and more preferably 140 mm or more. On the other hand, when the height of the side edge portion exceeds 250 mm, there is a hindrance to the smooth movement of the side edge portion. Therefore, the height of the side edge portion is preferably 250 mm or less, more preferably 200 mm or less, and more preferably 180 mm or less.

Further, the seat surface may be provided as the above-mentioned restriction means, and a bulge portion which is more bulged than the periphery may be provided at the center end portion thereof (Application 6).

In this case, the ridge portion is formed in a shape along the seat portion of the user who has sat down, and the displacement between the seat surface and the buttocks of the user can be suppressed in a shape, and it is easy to be The sitting position of the user at the seat surface is consistent with the position at which the effective movement can be performed.

Further, the main body portion may include a core portion and a skin portion covering the core portion, and the core portion may have at least a bottom member positioned on the bottom surface side and a position on the seat surface side The seat member is formed of a different material, and the bottom member has a larger hardness than the seat member (Application 7).

In this case, by using a harder material at the above-mentioned bottom member, it is possible to alleviate the sinking of the bottom surface due to the weight of the user. Therefore, it is easy to maintain the slightly spherical shape of the bottom surface. Moreover, by using a relatively soft material in the seat member, it is possible to reduce the burden on the waist of the user and to improve the feeling of adhesion.

In addition, as the bottom member, for example, a plastic represented by polyurethane or polystyrene, or a foamed plastic represented by a rigid polyurethane foam or a polystyrene foam may be used in a load. A material that is not easily deformed when it is weighted.

Further, as the seat member, a flexible foamable plastic such as a soft polyurethane foam may be used. Further, as the seat member, a low resilience foam or the like can be used by the weight of the user. The material which is easily deformed by the load is as described above, and the seat member can also function as the above-described restriction means. Further, when the seat member is largely deformed by the sitting of the user, the height (lowest point) of the seat surface after the deformation is in the range of 100 mm to 450 mm, as described above. , can improve the effect of exercise.

Moreover, by providing the above-mentioned skin material, it is possible to suppress abrasion caused by the use of the exercise aid. As the skin material, a cloth, a paint, or the like may be used. However, it is preferable that the skin material disposed near the bottom surface is a material having high abrasion resistance.

Moreover, it is preferable that the above-described exercise aid is provided with a center of gravity at a position where the seat surface faces upward in a natural placement state (Application 8).

In this case, it is possible to limit the movement of the direction before the exercise aid is used to a minimum. In other words, it is a large operation that does not require, for example, upside down. Further, in a state where the seat surface is directed upward, the user can easily achieve balance. As a result, the exercise subsidy described above becomes easier for the user.

Further, preferably, the radius of curvature of the bottom surface is 130 to 250 mm (application 9).

When the radius of curvature of the bottom surface falls within the above-described specific range, the inclination of the seat surface in the movable range of the waist of the user can be restricted to a range suitable for the movement. In other words, it is possible to limit the inclination of the seat surface to the effect of improving the rotational motion, and it is also easy for the user to obtain a balance and is not easy to turn over. Within the range of the fall.

When the radius of curvature of the bottom surface is less than 130 mm, the inclination of the seat surface may become excessive in the movable range of the waist of the user. Therefore, there is a tendency for the balance of the user to collapse and fall over. Therefore, the radius of curvature of the bottom surface is preferably 130 mm or more, more preferably 150 mm or more, and more preferably 160 mm or more. On the other hand, when the radius of curvature of the bottom surface exceeds 250 mm, the inclination of the seat surface is likely to be insufficient, and for example, in the rotational movement of the waist or the like, the effect of the movement may be lowered. Therefore, the radius of curvature of the bottom surface is preferably 250 mm or less, more preferably 230 mm or less, and more preferably 220 mm or less.

Here, the radius of curvature of the bottom surface can be expressed by the radius of the imaginary circle as follows. First, a reference axis that extends through the grounding point and extends in the vertical direction is defined for the ground point of the bottom surface. Thereafter, at a longitudinal section including the main body portion of the reference axis, two points on the bottom surface having a distance of 50 mm in the vertical direction from the ground point were prepared. The radius of the imaginary circle passing through the two points of the two points and the ground point is the radius of curvature of the bottom surface.

Further, the present invention may be configured to include a support frame that is disposed between the bottom surface and the ground plane, and is configured to suppress tilting operation of the exercise aid by the installation of the support frame ( Application 10).

In this case, by providing the support frame as an intermediary, it is possible to suppress the unexpected tilting motion of the exercise aid. When it is not used, it is easy to keep the above exercise aids. Moreover, the exercise aid which can suppress the tilting operation by the above-mentioned support frame can also be utilized as a chair.

Further, the pair of right and left support handles may be separately formed separately from the exercise aid, and may include a grip portion that the user can grip and a ground contact surface. The grounding portion and the grounding portion are formed so as to be capable of suppressing a positional deviation of the grounding portion placed on the grounding surface, and the user can be configured by one side When the grip portion is gripped, the grounding portion is placed on the grounding surface to suppress the tilting operation of the exercise aid (Application 11).

The support handle is configured such that when the exercise aid is used, the user can mount the ground portion on the ground contact surface while holding the grip portion. As a result, when the exercise aid is used, the user can achieve balance by the three points of the foot and the pair of support handles. Further, the positional shift of the support handle can be suppressed by the anti-slip portion formed at the ground portion. As a result, the exercise subsidy described above becomes easier for the user.

[Examples] (Example 1)

An embodiment of the exercise aid described above will be described with reference to Figs. 1 to 11 . The exercise aid 1 is generally provided as shown in Fig. 1, and has a body portion 10 provided with a seat surface 2 on which the user sits and a bottom surface 3 which is slightly spherical. . Further, as shown in FIG. 3, the height H of the lowest point 20 of the seat surface 2 is in the range of 100 to 450 mm, and is provided with the buttocks from the seat surface 2 for the user who has sat down. In the case of the offset, the side edge portion 4 and the ridge portion 21 of the restraining means are suppressed.

In addition, in the following directions, the directions of the upper and lower or the front and rear directions are used for the purpose of marking the orientation of the exercise aid 1 in a state where the user straightens the back and sits down on the seat surface 2.

The main body portion 10 is generally as shown in Fig. 5. When viewed from the side (upper side) of the bottom surface 2, the outer contour line is slightly elliptical, and the inner side thereof constitutes the seat surface 2. In front of the seat surface 2, that is, at the center front end portion, as shown in Figs. 3 and 6 to 8, a ridge portion 21 having a smooth curved surface and being more raised than the periphery is provided. Moreover, the main body portion 10 is generally as shown in FIG. 1 and FIG. 2, and when viewed from the front, the outer contour line has an arc shape, and at the side of the seat surface 2, there is a seat surface. 2 and stand up a pair of side edges 4.

As shown in FIG. 3, the seat surface 2 is provided with a lowest point 20 in a direction opposite to the central portion 22 of the bottom surface 2, that is, in a direction opposite to the ridge portion 21. Further, the seat surface 2 is gently inclined from the peripheral portion toward the lowest point 20, and forms a continuous smooth curved surface.

Here, the height H of the seat surface 2 is generally as shown in FIG. 3, and the bottom surface 3 is grounded in such a manner that the central portion 22 of the seat surface 2 is disposed vertically above the grounding point 30. In the state, the height of the lowest point 20 of the seat surface 2 when the ground plane is used as a reference. This is the same as the above, when the user sits down on the seat 2 and sets the back in a straight natural state. The height from the ground plane up to the lowest point 20 of the user's buttocks is substantially the same. Further, in this example, the height H of the seat surface 2 is set to 185 mm.

The bottom surface 3 has a slightly spherical shape as shown in FIG. 2 and FIG. 3, and the radius of curvature R measured in the front-rear direction is 177 mm.

The ridge portion 21, as shown in Fig. 5, is formed at a central front end portion of the seat surface 2, that is, a portion where the user's thigh portion is disposed. The ridge portion 21 is formed on a straight line connecting the lowest point 20 of the seat surface 2 and the central portion 22 of the seat surface 2, as shown in FIG. 3, and is gradually raised from the periphery toward the front end direction. . Further, as shown in FIGS. 6 to 8, generally, the seat surface 2 including the ridge portion 21 is formed by a continuous smooth curved surface.

The pair of side edges 4, as shown in Figs. 1 and 2, are on both sides of the side of the cover seat 2, that is, the pelvis of the user who is seated on the seat surface 2. The position of the side of the part is formed by sandwiching the seat surface 2 and standing up. The pair of side edges 4 are formed as viewed from the front as shown in FIG. 2, and are curved toward the seat surface 2 side as they advance upward. On the other hand, the side of the pair of side portions 4 that is in contact with the user is generally oriented as shown in FIGS. 4 and 6 to 8 so that the central portion thereof is more oriented than the surrounding portion. A gentle curved surface formed by recessing on the opposite side of the seat surface 2. Thereby, the pair of side edges 4 are configured to follow the shape of the buttocks and the waist of the user. Also, as shown in Figures 6-8, on the side of a pair The surface of the square portion 4 that is in contact with the user and the seating surface 2 are formed by a continuous smooth curved surface.

Further, the pair of side edges 4 are generally as shown in FIG. 3, and the outer contour when viewed from the side is gradually narrowed as it goes upward from the seat surface 2. The way is formed into a parabolic shape. In this example, the height I of the side edge portion 4 is set to 178 mm. Here, the height I of the side edge portion 4 is generally as shown in FIG. 3, and is the same as the height H of the seat surface 2, from the lowest point 20 of the seating surface 2 when the grounding state is set until The height from the highest point 40 of the side edge portion 4.

Next, an example of the method of using the exercise aid 1 will be described. The user, as shown in FIG. 9, is seated on the seat surface 2 of the exercise aid 1 in a state in which the back is straight. Thereafter, by tilting or rotating the waist while maintaining the position of the upper body, the seat surface 2 can be moved in the horizontal direction and inclined as shown in Fig. 11 . Thereby, as shown in FIG. 10, in general, the muscles around the waist can be subjected to a motion such as a rotational motion or a twisting motion.

Next, the effect of the exercise aid 1 will be described. The exercise aid 1 has a height H of the lowest point 20 of the seat surface 2 falling within a specific range, and the bottom surface 3 is slightly spherical. Therefore, in a state where the user is seated, the waist portion is moved by using the grounded foot as a base point, and the seat surface 2 can be tilted in the whole direction while the bottom surface 3 is maintained at the ground. Further, since the exercise aid 1 has the above-described specific height H, it is possible to ensure that the movement range of the seat surface 2 accompanying the inclination of the seat surface 2 is large within an appropriate range. That is, It can widen the movable range of the user's waist. Therefore, for example, the radius of rotation in the rotational motion of the waist is increased, and the muscles of the waist can be effectively subjected to the torsional motion. In this manner, by using the exercise aid 1 in which the height H of the seat surface 2 is set within the above-described specific range, the effect of the movement of the waist or the like can be improved.

Further, the exercise aid 1 is provided as a restriction means, and includes a side edge portion 4 that stands up in a pair between the seat surface 2 and a raised portion 21 that is disposed at a center front end portion of the seat surface 2. Further, the side edge portion 4 is configured such that the height I from the lowest point 20 of the seat surface 2 to the highest point 40 of the side edge portion 4 falls within the above-described specific range. On the other hand, the surface of the seat surface 2 and the raised portion 21 and the pair of side edges 4 that are in contact with the user are formed in a continuous manner along the shape of the buttocks, the waist and the thigh of the user. The smooth curved surface is configured to support the shape of the user's buttocks, waist or thigh. As a result, the user is less likely to hold the hand support on the exercise aid 1 while exercising. In addition, the exercise assisting device 1 is a sports support that can smoothly perform the rotational movement of the waist, such as the hip, which is difficult to be displaced from the seat surface 2 at the sitting position where the exercise can be performed effectively. With. In this way, the effect of complementing each other by the specific range of the seat height H and the restriction means can sufficiently improve the movement effect of the waist.

Further, since the height H of the seat surface 2 is set within the above-described specific range, the burden when the user sits down is reduced. Therefore, it is easy for the user to be a user.

Further, the radius of curvature R of the bottom surface 3 falls within the above specific range. Therefore, it is possible to limit the inclination of the seat surface 2 in the movable range of the waist of the user to a range suitable for the movement, and to limit the inclination of the seat surface 2 to the effect of improving the rotational motion or the like. It is large enough and also allows the user to easily achieve a balance that is not easy to fall over.

As described above, according to the above aspect, it is possible to provide the exercise aid 1 which is easy to use.

(Example 2)

In this example, the main body portion 10 of the exercise aid 1 in the first embodiment is configured by a plurality of materials. The exercise assisting device 1 of the present embodiment has a core portion 17 and a skin portion 15 covering the core portion 17 and a core portion 17 by the main body portion 10 as shown in FIG. The bottom member 13 positioned at the side of the bottom surface 3 is formed of a material different from the seating member 12 positioned at the side of the seating surface 2.

The bottom member 13 and the seat member 12 are formed by using urethane foams having different hardnesses. The seat member 12 is formed of a flexible soft urethane foam which is configured to be able to follow and deform a certain degree to the surface shape of the body when the user sits down. On the other hand, the bottom member 13 is formed of a hard urethane foam having a larger hardness than the seat member 12, and is difficult to be deformed when the user sits on the seat surface 2.

a pair of side edges 4 are integrally formed with the bottom member 12 It is formed of a soft urethane foam of the same material. Thereby, the pair of side edges 4 are provided with flexibility, and are formed so as to be able to press the pelvic portion of the user sitting on the seat surface 2 from the side. In addition, the soft amine urethane foam used in the seat member 12 in this example is measured by a Shaw hardness tester (model LX-C: manufactured by Wenzhou Shandu Instrument Co., Ltd.). The hardness is 12 degrees.

At the skin portion 15, a fabric is used, and a fabric having a high abrasion resistance is used at a portion where the bottom surface 3 is easily worn.

Moreover, the exercise aid 1 of this example is provided with the center of gravity in the position where the seat surface 2 is upward in the natural mounting state. For example, in this example, as shown in FIG. 12 and FIG. 13, the bottom member 13 having a relatively high density is formed in a shape that is slightly rotationally symmetrical with respect to the central axis, and is set for the center of gravity. The other constitution is the same as that of the first embodiment.

Next, the effect of this example will be explained. In the natural placement state, the exercise aid 1 of the present embodiment is provided with a center of gravity at a position where the seat surface 2 faces upward. Therefore, it is possible to limit the movement of the direction before the exercise aid 1 is used to a minimum. Moreover, in a state in which the seat surface 2 is directed upward, the user can easily achieve balance, and therefore, it is possible to perform the movement safely. As a result, the exercise aid 1 is more user-friendly.

Further, the side edge portion 4 is provided with flexibility, and is formed so as to be able to press the pelvic portion of the user sitting on the seat surface 2 from the side. Thereby, the pair of side edges 4 can be used The part of the pelvis is kept. Therefore, a sense of unity is generated between the pelvic portion of the user and the seat surface 2, and the movement of the pelvic portion becomes a movement that more easily follows the seat surface 2. As a result, the torsional movement of the muscles of the user's waist can be performed more efficiently, and the effect of the exercise can be further improved.

Further, the main body portion 10 includes a core portion 17 and a skin portion 15 covering the core portion 17, and the core portion 17 is formed by the bottom member 13 at the side of the bottom surface 3 and the seat surface 2 The seat member 12 at the side is formed of a different material, and the hardness of the bottom member 13 is greater than the hardness of the seat member 12. Therefore, by using a harder material at the bottom member 13, it is possible to substantially eliminate the sinking of the bottom surface 3 due to the weight of the user. As a result, it is easy to maintain the shape of the bottom surface 3. Moreover, by using a relatively soft material at the seat member 12, the burden on the waist of the user can be reduced, and the feeling of adhesion can be improved, and the restriction on the hip of the user can be suppressed. Means to work. In addition to this, the same effects as those of the first embodiment can be obtained.

In addition, in the first and second embodiments, the plural portions of the pair of side portions 4 and the like function as a restriction means, but the portions that function as the restriction means are provided as long as they are provided. It can be more than one place. For example, in the first embodiment, it is also possible to adopt a configuration in which a pair of side edges 4 are not formed, and the seat surface 2 and the ridge portion 21 are used to the user's buttocks or The stock unit is shaped to support and acts as a limiting measure. Further, conversely, as a restriction means, a configuration in which only one pair of side edges 4 are provided without providing the ridge portion 21 may be employed. to make. of course. In addition to the form of the shape support, the skin portion 15 may be a cloth having a large friction coefficient, and the friction between the seat surface 2 and the user's buttocks may be suppressed by friction. the way.

In the case of ○, when it is three or more, it is set as △, and when it is two or less, it is set as x, and it is set as the exhibitor, and the case of ◎, ○, and △ is judged as the tolerable result.

<radius of curvature of the bottom surface R>

The test bodies 21 to 30 in which the curvature radius R of the bottom surface 3 in the second embodiment was variously changed as shown in Table 3 were produced. Thereafter, in Table 3, the ease of the movement when the waist was rotated using the test bodies was demonstrated. In addition, the symbol of ◎, ○, △, and × in Table 3 is a number of people who are likely to perform a rotational motion, and is ◎ in the case of 10 or more among 10 people, and is 5 or more. In the case of ○, when it is three or more, it is set as △, and when it is two or less, it is set as x, and it is set as the exhibitor, and the case of ◎, ○, and △ is judged as the tolerable result.

<hardness of seat member>

The test bodies 31 to 38 in which the hardness of the seat member 12 of the exercise aid 1 in the second embodiment was changed as shown in Table 4 were variously changed. Thereafter, in Table 4, the ease of the movement when the waist was rotated using the test pieces was demonstrated. In addition, the symbols of ◎, ○, △, and × in Table 4 are the number of people who feel that it is easy to perform the rotational movement, and the number of the eight persons is eight or more, and is ◎, and is five or more. In the case of ○, when it is three or more, it is set as △, and when it is two or less, it is set as x, and it is set as the exhibitor, and the case of ◎, ○, and △ is judged as the tolerable result.

As can be seen from Table 1, the exercise aid 1 is preferably a height that can be effectively exercised by setting the height H of the seat surface 2 to at least 105 mm to 448 mm, and is preferably 143 mm to 293 mm. It will become even more ideal when it is 160mm~191mm.

Further, as can be seen from Table 2, in general, the exercise aid 1 can easily achieve the pelvic portion of the user at the same time by setting the height I of the pair of side portions 4 to at least 85 mm to 255 mm. It is a person who is more likely to perform sports when it is more effective in maintaining the effect of smooth movement and achieving smooth movement. When it is 120mm to 250mm, it is easier to perform sports. When it is 141mm~178mm, it is particularly easy to perform sports.

Further, as can be seen from Table 3, in general, the exercise assisting tool 1 can set the inclination of the seat surface 3 to at least 125 mm to 260 mm, thereby making it possible to increase the inclination of the seat surface for the purpose of improving the rotational motion or the like. It is said to be sufficiently large, and it is also limited to the range where the user does not easily fall over, and becomes more likely to be an exerciser. When 140mm~243mm, the system becomes more versatile. For those who are easy to exercise, when they are 164mm~212mm, they are particularly easy to exercise.

Further, although the hardness of the seat member 12 is not particularly limited, the exercise aid 1 can be known as shown in Table 4, and at least the Shore hardness tester (Model LX-C: Wenzhou Mountain) The hardness measured by the Instrument Co., Ltd. is 3 to 25 degrees, which reduces the burden on the user's waist and improves the feeling of adhesion, making it easier for people to exercise. When 7 to 20 degrees It is a person who is more likely to exercise, and when it is 8 degrees to 16 degrees, it is particularly easy to perform sports.

(Example 4)

The exercise aid 1 of this example is generally provided as shown in Fig. 14, and has an annular support frame 16. As shown in FIG. 15, the support table 16 is generally configured to be disposed between the bottom surface 3 and the ground plane, and is capable of suppressing the tilting operation of the exercise aid 1 by the intermediary of the support station 16.

In this way, by providing the support frame 16 as an intermediary, it is possible to suppress the unexpected tilting motion of the exercise aid 1 , and therefore it is easy to store the exercise aid 1 when not in use. Further, the exercise aid 1 capable of suppressing the tilting operation by the support frame 16 can be used as a chair.

(Example 5)

The exercise aid 1 of this example is as shown in FIG. 16 and FIG. In general, it is provided separately from the exercise aid 1 and has a pair of right and left support handles 18. As shown in FIG. 16, the support handle 18 is provided with a grip portion 180 that is configured to be slightly arcuately configured to be gripped by a user. Further, at both ends of the grip portion 180, as shown in Fig. 17, a substantially cylindrical land portion 181 placed on the ground contact surface is provided.

As shown in FIG. 17, the both ends of the ground portion 181 are provided with a rubber-made anti-slip portion 182 that is configured to be capable of suppressing the positional displacement of the land portion 181 placed on the ground plane. .

The support handle 18 is configured such that when the exercise aid 1 is used, the user can hold the ground portion 181 on the ground contact surface while holding the grip portion 180, thereby suppressing the tilting operation of the exercise aid 1 . Thereby, the user can achieve balance by the three points of the leg portion and the pair of support handles 18. Moreover, the positional deviation of the support handle 18 can be suppressed by the anti-slip portion 182 formed at the ground portion 181. As a result, the exercise aid 1 is more user-friendly.

Further, in the first to third embodiments, the case where the curvature radius R of the bottom surface 3 is slightly equal in the front-rear direction and the left-right direction is shown. However, the bottom surface 3 may be used. The radius of curvature R is a configuration in which the values are different in the front-rear direction and the left-right direction. In this case as well, as long as the radius of curvature R in the front-rear direction and the radius of curvature R in the left-right direction fall within the above-described specific range, the inclination of the seat surface 2 can be restricted as described above. The effect of the rotational motion is sufficiently large and can also be easily balanced by the user without being overturned.
