[Solution] A training tool 30 in which a first annular part 11 and a second annular part 12 are linked by a linking part 13 is configured such that when a user uses the training tool 30, the force needed to expand the tool in a longitudinal direction is different between when the first annular part 11 is grasped and expanded so as to achieve a reference length W1 and when the second annular part 12 is grasped and expanded so as to achieve the reference length W1, and the force needed to expand the tool in a transverse direction intersecting the longitudinal direction, when the first annular part 11 is grasped and expanded so as to achieve the reference length W1 and when the second annular part 12 is grasped and expanded so as to achieve the reference length W1, is different from the force needed to expand the tool in the longitudinal direction.

Description

training equipment

The present invention relates to training equipment that can be used for exercises to train muscle strength.

Conventionally, as an exercise to train muscle strength, an exercise in which a ring-shaped rubber band is stretched is known. Furthermore, there is known a training tool that can change the resistance (load) by selectively stretching each part formed in a ladder shape (for example, see Patent Document 1).

Japanese Patent Application Publication No. 2003-180867

However, there is still room for improvement regarding the configuration of generating multiple types of resistance using one training tool. For example, if you want to increase the resistance during similar training (exercise), or if you want to slightly differ the distance between the left and right handles, you may need to prepare different training equipment.

The present invention was created to solve these problems. That is, an object of the present invention is to provide a training tool in which the distance and resistance force of a handle for gripping the training tool can be suitably set in a plurality of stages.

The training tool according to claim 1 is a training tool configured to enable a user to exercise to train muscle strength by gripping a plurality of parts and performing a deformation operation to expand the gripped parts so as to be separated from each other. , a first annular portion (11) that is continuous in an annular shape with a longitudinal direction on a predetermined direction side, and a first annular portion (11) that is formed large over the entire circumference with respect to the first annular portion (11) and is on the predetermined direction side. a second annular part (12) whose longitudinal direction is in the same direction as , and a connecting part (13) that connects the second annular part (12) and the first annular part (11). In the longitudinal direction, the first annular portion (11) is held and expanded to a predetermined length, and the second annular portion (12) is held and expanded to a predetermined length. The force required for expansion is different depending on the case where the first annular portion (11) is gripped in the transverse direction intersecting the longitudinal direction and expanded to the predetermined length. The force required for expansion in at least one of the case where the second annular portion (12) is gripped and expanded to the predetermined length is the force necessary for the expansion in the longitudinal direction. are characterized by being configured differently.

According to the training tool according to claim 1, the user can grip each of the first annular part (11) and the second annular part (12) along the longitudinal direction. Since it is possible to carry out a movement in which the user grips a portion along the lateral direction and a movement in which the portion is gripped along the transverse direction, it is possible to carry out movements that generate various resistance forces. That is, in the longitudinal direction, the distance of the handle can be changed in two steps depending on when gripping the first annular part (11) and when gripping the second annular part (12), and , it is possible to set the distance of the handle in two stages also in the lateral direction. Therefore, it is possible to easily set multiple levels of handle distances with one training tool.

The training tool according to claim 2 is the training tool according to claim 1, in which the hole portion located inside the first annular portion (11) is divided into a plurality of parts when viewed from a direction in which the hole portion is visible. An inner continuous part (14) is provided inside the hole part so as to be continuous, and both end parts of the inner continuous part (14) are connected to the first annular part (11) or connected to the first annular part (11). It is configured to be connected to the outside of the annular portion (11).

According to the training tool according to claim 2, the inner continuous portion (14) can suppress deformation of the first annular portion (11) and the second annular portion (12), and The cross-sectional shape of the annular portions (11, 12) is such that the cross-sectional shape of the annular portion (11) and the second annular portion (12) is set to be elongated and easy to grasp, while increasing the resistance against deformation operations. You can increase the degree of freedom in setting the thickness and resistance.

According to the present invention, it is possible to provide a training tool in which the distance and resistance force of the handle for gripping the training tool can be suitably set in multiple stages.

The training tool of the present invention allows a user to perform an exercise to train muscle strength by gripping multiple parts and expanding the gripped parts so that they are separated, and the distance of the handle and the resistance force can be adjusted. It is configured so that it can be set in multiple stages. Embodiments of the present invention will be described below with reference to the drawings.

<Overall configuration of

training equipment

10, 20, 30>
FIG. 1 is a diagram showing

training equipment

10, 20 of the present invention, and FIGS. 1(a) and 1(b) are a front view and a side view showing the training equipment 10 having an oval shape. 1(c) is a front view showing a training tool 20 having an oval shape.

The training tool 10 includes a first annular portion 11, a second annular portion 12, and a connecting portion 13. The first annular portion 11 and the second annular portion 12 are both formed to have a longitudinal direction and a transversal direction when viewed from the front where the

holes

11a and 12a formed inside are visible. .

The first annular part 11 is an elliptical annular part whose longitudinal direction is longest in one direction (left-right direction in FIG. 1(a)), and the outer shape changes as the angle increases with respect to the longitudinal direction. The length becomes short, and the length is continuous so that the vertical width direction side (vertical direction in FIG. 1(a)) is the shortest.

The second annular part 12 is an elliptical annular part that is formed to be large over the entire circumference relative to the first annular part 11, and the same direction side as the longitudinal direction of the first annular part 11 is the longitudinal direction. The first annular portion 11 is integrated with the first annular portion 11 by the connecting portion 13 in the direction shown in FIG.

The connecting portions 13 are provided at multiple locations to connect the first annular portion 11 and the second annular portion 12. FIG. 1A shows an example in which the connecting portions 13 are provided at four locations. The hole 12a formed inside the second annular part 12 is divided into four arc-shaped regions by four connecting parts 13 between the first annular part 11 and the second annular part 12. has been done.

The training tool 10 is formed so that a force above a certain level is required to change the shape of the two

annular parts

11 and 12 that are integrated by the connecting part 13. Specifically, the material and cross-sectional shape of the training tool 10 are such that the material and the cross-sectional shape have a hardness (elastic modulus) with a constant stiffness that allows the original shape to be maintained in the initial state where no load is applied due to exercise. Set. Setting the hardness of the training tool 10 will be described later with reference to FIG. 3.

The number of connecting portions 13 should be at least three or more so that the shapes of the first annular portion 11 and the second annular portion 12 can be easily maintained in substantially the same shape according to deformation. It is preferable that the number of locations is 4 or more. In addition, the position of the connecting portion 13 is such that the long section Ha corresponding to the longitudinal direction and the short section Hb corresponding to the transverse direction are removed so that the user can easily grasp the sections Ha and Hb. It is preferable to set these at four locations, and as in this embodiment, it is preferable to provide at four locations located between the long section Ha and the short section Hb.

The two

annular parts

11 and 12 may be made of a material that can be elastically deformed by a user's deformation operation, and various materials such as an elastomer having rubber elasticity and polyvinyl chloride are exemplified. The two

annular portions

11 and 12 may be made of the same material or may be made of different materials. Further, the connecting portion 13 may be made of the same material as the

annular portions

11 and 12, or may be made of a different material. For example, the

annular parts

11 and 12 may be made of an elastomer that is easily elastically deformable, and the connecting part 13 may be made of a hard resin that is less deformable than the

annular parts

11 and 12, such as nylon or polyacetal.

Here, the two

annular portions

11 and 12 are not limited to an elliptical annular shape, but may be an annular shape whose longitudinal direction is in one direction, such as an ellipse or a substantially rectangular shape with arcuate corners. It may be formed into other shapes, if any. Further, as for the cross-sectional shape of the two

annular portions

11 and 12, the outer peripheral shape may be circular or elliptical, or may be oval or polygonal (for example, rectangular). Moreover, as for the shape of the inside of the cross section, it may be formed solid without a space, or it may be formed hollow with a space. Although it is preferable that the two

annular parts

11 and 12 have the same cross-sectional shape, they may have a configuration in which at least some of them have different shapes.

The cross-sectional shape and size of the connecting portion 13 may be the same as those of the

annular portions

11 and 12, or may be different in one or both of the cross-sectional shape and size. However, when the

annular portions

11 and 12 and the connecting portion 13 are integrally molded, it is preferable to make the

annular portions

11 and 12 have substantially the same cross-sectional shape as the

annular portions

11 and 12 to easily suppress the occurrence of sink marks and improve the appearance. It is preferable that it can be done.

Here, the training tool 10 is exemplified as having a constant external shape (thickness and thickness) around the entire circumference of the

annular parts

11 and 12, but there are parts of the

annular parts

11 and 12 that have partially different shapes. May include. For example, the intersection portion where the connecting portion 13 is connected to the

annular portions

11 and 12 may be configured to include a portion of a different shape as a part of the

annular portions

11 and 12, such as having a larger thickness than other portions. .

The shape of the two

annular parts

11 and 12 is such that the length between the length in the longitudinal direction and the length in the width direction in the second annular part 12 is different from that of the first annular part. A configuration may be adopted in which the length in the longitudinal direction of 11 is set. Thereby, it is possible to set the distance of the handle in four stages in the initial state, and it is also possible to make the increments of the distance of the four stages of the handle substantially constant. Further, the shapes of the two

annular parts

11 and 12 may be set so that the length in the longitudinal direction of the first annular part 11 and the length in the transverse direction of the second annular part 12 are approximately the same. good. In this case, it is possible to add a function to the training tool 10 that allows exercise to be performed with different resistance forces while using the same distance as the initial state.

An inner continuous portion 14 is provided inside the first annular portion 11 . The inner continuous portion 14 is configured to divide the hole portion 11a into a plurality of pieces when viewed from the front where the hole portion 11a of the first annular portion 11 can be visually recognized. That is, the inner continuous portion 14 is continuously provided inside the hole portion 11a so that both one end side and the other end side are connected to the inner peripheral portion of the annular portion 11. Specifically, the inner continuous portion 14 is constructed by combining four linear rod-shaped portions, and the four rod-shaped portions are connected at the central portion, thereby dividing the hole portion 11a into four regions. . This inner continuous portion 14 suppresses deformation of the first annular portion 11 and the second annular portion 12 in response to deformation operations. As a result, while the first annular portion 11 and the second annular portion 12 are set to be elongated and have a cross-sectional shape that is easy for the user to grasp, the training tool 10 can be easily deformed during exercise using the training tool 10. It is possible to increase the degree of freedom in setting the resistance force, such as increasing the resistance force.

The inner continuous portion 14 is formed by combining two linear portions extending from one portion of the first annular portion 11 to another such that they intersect. Thereby, even if the inner continuous portion 14 is elongated, the resistance to deformation operations can be efficiently increased. Note that the inner continuous portion 14 is not limited to a straight line shape, but may be formed in a curved shape or a polygonal shape instead of or in addition to this, or may have a portion that branches into two or more parts in the middle. It is also possible to have a configuration in which the components are included and connected.

Both end portions of the inner continuous portion 14 are connected to a portion of the first annular portion 11 where the connecting portion 13 is provided. Thereby, the inner continuous portion 14 can easily exert the action of generating a resistance force through the connecting portion 13 even when the second annular portion 12 is deformed. Note that both end portions of the inner continuous portion 14 do not necessarily need to be connected to the location where the coupling portion 13 is provided in the first annular portion 11; A configuration may be adopted in which only a part of the portion 14 is connected, or a configuration in which the entire inner continuous portion 14 is connected to a location where the connecting portion 13 is not provided.

Here, although FIGS. 1(a) and 1(b) illustrate a case where both end portions of the inner continuous portion 14 are connected to the inner peripheral portion of the first annular portion 11, The portion 14 may be configured to be connected to an outer side of the inner peripheral portion of the first annular portion 11 . For example, the inner continuous part 14 is provided at a position shifted from the inside of the hole part 11a, and the front side of the first annular part 11 (the front side in the direction perpendicular to the paper in FIG. 1(a)) or the back side (in the figure 1(a)), the inner continuous portion 14 may be connected to the first annular portion 11 (see FIG. 2(b)). Further, the inner continuous portion 14 may be connected not to the first annular portion 11 but to the connecting portion 13 or the second annular portion 12 located outside the first annular portion 11. Further, each end portion of the inner continuous portion 14 is connected to the first annular portion 11 at only one place, but the two end portions of the first annular portion 11 and the second annular portion 12 are For example, the first annular portion 11 may be connected at two or more points outside the inner peripheral portion thereof, or the first annular portion 11 and the connecting portion 13 may be connected at two or more points. It is also possible to have a configuration in which they are connected in a section having a certain length, such as in a section having a certain length.

FIG. 1(c) shows a form of training equipment 20 in which the inner continuous portion 14 is not provided with respect to the training equipment 10 described above. In the explanation of the training tool 20, the same names and numbers are given to the parts to which the same configuration as the above-described training tool 10 can be applied, and the explanation is omitted. Even if the training tool 20 is not provided with the inner continuous portion 14, the user can exercise using the first annular portion 11 and the second annular portion 12. Moreover, FIG. 1(c) illustrates a case where the first annular portion 11 and the second annular portion 12 are formed in an oval shape.

Next, another form of training equipment 30 will be described with reference to FIG. 2. FIG. 2 is a diagram showing a plurality of types of forms using a training tool 30 that is a combination of a plurality of parts, and FIGS. 2(c) and 2(d) show a form in which the inner continuous part 14 is bent in the longitudinal direction, and FIG. 2(e) and FIG. 2(f) show a form in which the inner continuous part 14 is arranged bent in the longitudinal direction. 2 shows a form in which the inner continuous portion 14 is bent in the lateral direction.

The training tool 30 is constructed by combining a plurality of parts so that the inner continuous part 14 can be attached to and detached from the two

annular parts

11 and 12. The training tool 30 can adopt various configurations such as materials and cross-sectional shapes of the

training tools

10 and 20 described above, and the same structure can be applied to the

training tools

10 and 20 described above. Names and numbers are given, and explanations are omitted.

The training tool 30 includes

annular members

31 and 32 forming two

annular parts

11 and 12, two rod-shaped

members

33 and 34 forming an inner continuous part 14, and a connecting part 35. The two

annular members

31 and 32 include a first annular member 31 with a small diameter corresponding to the first annular portion 11 and a second annular member 32 with a large diameter corresponding to the second annular portion 12. The first annular member 31 and the second annular member 32 are integrated by a portion of the rod-shaped

members

33 and 34 functioning as the connecting portion 13.

The rod-shaped

members

33 and 34 are members in which portions corresponding to the connecting portion 13 and the inner continuous portion 14 are integrated, and are configured in a linear shape. In addition, as shown in FIGS. 2(a) and 2(b), in the direction view (side view) of FIG. 2(b) where the

holes

11a and 12a in the two

annular members

31 and 32 are not visible, the two Rod-shaped

members

33 and 34 are arranged on both sides of the

annular members

31 and 32. The two rod-shaped

members

33, 34 are provided with

bolt portions

33a, 34a for integrating with the two

annular members

31, 32.

The connecting component 35 is constituted by a nut that can be fitted into the tip portions of the

bolt portions

33a, 34a protruding from the rod-shaped

members

33, 34. In the first annular member 31 and the second annular member 32, shaft holes 36 through which the

bolt parts

33a and 34a can be inserted are formed at locations corresponding to the

bolt parts

33a and 34a. A connecting component 35 is attached to a portion protruding on the opposite side of 32. Thereby, the two

annular members

31 and 32 and the rod-shaped

members

33 and 34 are integrated. Note that the mounting structure of the rod-shaped

members

33 and 34 to the

annular members

31 and 32 is not limited to a structure that combines bolts and nuts, but may be constructed using other mounting structures such as integration by fitting together by press-fitting. It's okay. Further, it is not necessarily necessary to use a removable mounting structure, and a non-removable mounting structure such as adhesive fixation, which partially breaks when separated, may be used. However, in order to make it possible to vary the resistance force (load) of movement, it is preferable to use a mounting structure in which the

annular members

31, 32 and the rod-shaped

members

33, 34 can be separated.

Here, the two

annular members

31 and 32 do not need to be configured as separate parts, and the training tool in which the two

annular members

31 and 32 are connected by the connecting part 13 (for example, the training tool shown in FIG. 20), the training tool 30 may be configured such that rod-shaped

members

33 and 34 can be attached thereto. In this case, although the length of the rod-

like members

33, 34 does not necessarily extend to the portion corresponding to the connecting portion 13, deformation of the two

annular portions

11, 12 can be efficiently suppressed by the inner continuous portion 14. In addition, it is preferable that the rod-shaped

members

33 and 34 be connected and fixed to the two

annular parts

11 and 12, or to at least one of the

annular parts

11 and 12 and the connecting part 13.

Next, another method of using the training tool 30 using two

annular members

31 and 32 and two rod-

like members

33 and 34 will be described. The training tool 30 is configured such that the resistance force against the deformation operation can be changed by changing the attachment positions of the two rod-

like members

33 and 34.

In Figs. 2(c) and 2(d), the resistance force is set high against deformation operations in the longitudinal direction (left-right direction in Fig. 2(c)), and the resistance force is set high in the transverse direction (Fig. 2(c) The case where the resistance force is set low for deformation operations in the vertical direction) is illustrated. The rod-

like members

33 and 34 are fixed at one end to the

annular members

31 and 32, then reversed while passing through the inside of the hole 11a, and then fixed at the opposite end to the annular members 31 and 32 (see FIG. 2(d) ) see arrow). The fixing position on the opposite side is a position where the rod-

like members

33, 34 are continuous in the longitudinal direction of the annular parts 11, 12 (annular members 31, 32). As a result, the resistance force is set high against the deformation operation in the longitudinal direction, which is a movement with a different resistance force than when the rod-shaped

members

33 and 34 are connected in the positions shown in FIGS. 2(a) and 2(b). These movements can be performed without using any separate parts.

2(e) and 2(f), the resistance force is set high against the deformation operation in the lateral direction (vertical direction in FIG. 2(e)), and the resistance force is set high in the longitudinal direction (vertical direction in FIG. 2(e)). The example shows a case where the resistance force is set low for deformation operations in the left-right direction). The rod-

like members

33, 34 are fixed at positions where the rod-

like members

33, 34 are continuous in the lateral direction of the annular portions 11, 12 (annular members 31, 32). As a result, the resistance force is different from that when the rod-

like members

33 and 34 are connected in the positions shown in FIGS. Even when the rod-

like members

33 and 34 are connected, a movement with a high resistance against deformation operations in the lateral direction can be performed without using separate parts, as a movement with different resistance forces.

<Resistance of training equipment 30>
Next, with reference to FIG. 3, the relationship between basic exercise using the training tool 30 and resistance force will be described. FIG. 3 shows a movement in which the training tool 30 is pulled in the left-right direction (hereinafter referred to as the "basic exercise") while changing the position of the handle that grips the training tool 30 (hereinafter referred to as the "gripping position"). FIG. 3 is a diagram illustrating the relationship between the distance of the handle and the resistance force when holding the handle. In order to make it easier to understand the shape of the training tool 30, the shapes of the

annular portions

11 and 12 shown in FIG. 3 are shown in a different shape from when they are actually stretched and elastically deformed.

3(a1) and FIG. 3(a2) show a case where the basic exercise is performed by grasping the second annular portion 12 (second long section Ha2) in the longitudinal direction of the training tool 30 as the grasping position. ing. The hardness of the training tool 30 is set to an elastic modulus that does not deform the form of the training tool 30 in the initial state shown in FIG. 3(a1). That is, in selecting the specifications that affect the elastic modulus, such as the cross-sectional shape and material, a small amount of force will not cause the training tool 30 to stretch out horizontally too much, and the shape of the training tool 30 will be maintained at the initial length Wa, which corresponds to the distance of the handle in the initial state. The specifications are selected. Furthermore, when the training tool 30 is stretched from the initial length Wa, the resistance force gradually increases in proportion to the amount of deformation, and when the training tool 30 is stretched to a certain reference length W1, the maximum resistance force Fa (for example, 15 N) increases. Each specification is selected to occur. Thereby, different resistance forces can be generated by selecting the gripping position, and it is possible to easily set the distance of the handle and the resistance force in many stages using one training tool 30.

FIGS. 3(b1) and 3(b2) show a case where the basic exercise is performed by grasping the first annular portion 11 (first long section Ha1) in the longitudinal direction of the training tool 30 as the grasping position. ing. In this case, compared to the resistance force Fa when gripping the second annular portion 12 (second long section Ha2), a large resistance force Fb (for example, , 30N) occurs. That is, in the longitudinal direction, the first annular part 11 is held and expanded to the reference length W1, and the second annular part 12 outside the first annular part 11 is held and expanded to the reference length W1. The force required for expansion differs between the case of expansion and the case of expansion to reach W1. Therefore, two different types of resistance forces can be generated depending on the gripping position in the longitudinal direction.

FIGS. 3(c1) and 3(c2) show a case where the basic exercise is performed by grasping the second annular portion 12 (second short section Hb2) in the lateral direction of the training tool 30 as the grasping position. It shows. In this case, the resistance force Fc (for example, 30 N) when stretching from the initial length Wc to the reference length W1 is larger than the resistance force Fa when gripping the second long section Ha2. Also, compared to the resistance force Fb when gripping the first long section Ha1, the difference between the resistance force Fc when stretching from the initial length Wc to the reference length W1 is greater than the resistance force Fb when gripping the second long section Ha2. is smaller than the resistance force Fa in the case of

Here, the cross-sectional shape of the training tool 30 is adjusted so that the resistance force Fc when the second short section Hb2 is gripped is approximately the same as the resistance force Fb when the first long section Ha1 is gripped. Specifications such as materials may be selected, or specifications may be selected to provide different resistance forces Fc (for example, 35 N). Further, as the length setting of the

annular parts

11 and 12, the initial length Wc is set to be the same as the initial length Wb when the first long section Ha1 is gripped, and the initial length Wb , Wc may be the same, but the resistance forces Fb and Fc may be set to be different.

FIGS. 3(d1) and 3(d2) show a case where the basic exercise is performed by gripping the first annular portion 11 (first short section Hb1) in the short direction of the training tool 30 as the gripping position. It shows. In this case, compared to the resistance force Fa when gripping the second long section Ha2, the difference in resistance force when stretching from the initial length Wd to the reference length W1 is the largest difference, and the maximum resistance force Fd (For example, 45N) is generated.

In this way, when performing a basic exercise using one training tool 30, two gripping positions are set in the longitudinal direction and two gripping positions in the transverse direction, making it possible to make the resistance forces different. It is configured. Therefore, the training tool 30 can easily set four levels of handle distances, and can generate resistance forces corresponding to the distances of multiple types of handles for basic exercise. 30 can be provided.

<Specific examples of exercise>
Next, a basic exercise using the training tool 30 and other exercise examples will be described with reference to FIGS. 4 to 6 in addition to FIG. 3. Figures 4 to 6 show specific examples of how to use the training equipment.

As shown in FIG. 3, the basic exercise is an exercise in which the training tool 30 is grasped with both hands and stretched in the horizontal direction. By performing this basic exercise, you can train your pectoralis major, deltoid muscles, and triceps. In the basic exercise, by selecting either the two long sections Ha1, Ha2 or the two short sections Hb1, Hb2 as the grasping position of both hands, the distance of the grips can be adjusted to suit the object of strengthening muscle strength. Exercises can be performed with resistance.

FIG. 4 shows a vertical stretching exercise (hereinafter referred to as "vertical exercise") performed by stepping on the lower part of the training tool 30 with both feet and fixing it so that it does not move, and grasping the upper part on the opposite side with both hands. ) is exemplified. In the vertical movement, it is possible to select either the two long sections Ha1, Ha2 or the two short sections Hb1, Hb2 as the grasping position of both hands and the pressing position of both feet. You can change the force and change the location where resistance begins.

As for the vertical exercise, you can select and perform an exercise that corresponds to the muscles you want to train. Figures 4(a1) and 4(a2) show vertical movement by bending and straightening the lower back, and Figure 4(a1) shows the initial state of bending the lower back and leaning forward. 4(a2) shows a state in which the user is in a standing posture with his or her hips stretched out. By bending and straightening your lower back, you can train the erector spinae, biceps femoris, and gluteus maximus muscles.

Figures 4 (b1) and 4 (b2) show the vertical movement of the knee by bending and straightening it. Figure 4 (b1) shows the initial state with the knee bent, and Figure 4 (b2) shows , shows a state in which the knee is extended relative to the initial state. By bending and straightening your knees, you can train your gluteus maximus, quadriceps, and hamstrings.

Figures 4 (c1) and 4 (c2) show the vertical movement of the elbow by bending and straightening it. Figure 4 (c1) shows the initial state of the elbow being extended, and Figure 4 (c2) shows , shows a state in which the elbow is bent and the hand is raised relative to the initial state. In this bending and straightening of the elbow, a case is illustrated in which the

annular parts

11 and 12 are held with the opposite hands, and thereby the biceps brachii muscles can be mainly trained.

FIG. 5 shows an example of an exercise in which the training tool 30 is expanded with both feet (hereinafter also referred to as an "expansion exercise"). Figures 5(a1) and 5(a2) show an extension movement in which one foot is placed on the floor and the opposite foot is spread apart. The initial state is shown, and FIG. 5(a2) shows a state where the distance between the legs is widened. This expansion exercise allows you to train your gluteus maximus and gluteus medius muscles. Further, FIGS. 5(b1) and 5(b2) illustrate an expansion movement when the training tool 30 is turned in a different direction and the foot is placed on the first annular portion 11. In this way, by selecting the orientation of the training tool 30 and the position on which the foot is placed, it is possible to perform an expansion exercise suitable for the target of muscular strength enhancement.

FIG. 6 illustrates a push-up exercise using the training tool 20. FIGS. 6(a1) and 6(a2) show a person lying on a support table as an apparatus, with the lower side of the training tool 20 hooked on the support table, and a push-up exercise in which the upper side is pushed upward. It shows. This push-up exercise allows you to train your pectoralis major, triceps, and deltoid muscles. Moreover, FIG. 6(b1) and FIG. 6(b2) illustrate a push-up exercise when the training tool 20 is changed in direction and the second annular portion 12 is gripped. In this way, by selecting the orientation of the training tool 20 and the positions of both hands, it is possible to perform a push-up exercise suitable for the target of muscular strength enhancement.

<Additional functions of training equipment>
Next, functions that can be added to the basic configurations of the above-described

training tools

10, 20, and 30 will be described.

As a resistance force adjustment function, in the training tool 30 shown in FIG. 2, a plurality of

annular members

31 and 32 having different hardness may be prepared, which are constituted by

annular portions

11 and 12 having different hardnesses (elastic modulus). . Moreover, instead of this, or in addition to this, a plurality of rod-shaped

members

33 and 34 having different hardnesses may be prepared. By replacing either or both of the

annular members

31 and 32 and the rod-

like members

33 and 34, the resistance to movement can be varied more widely.

Furthermore, the mounting positions of the rod-

like members

33 and 34 can be changed by providing a plurality of locations (for example, shaft holes 36) where the rod-

like members

33 and 34 are attached so as to be lined up in the direction in which the rod-

like members

33 and 34 are continuous. The resistance force may be increased or decreased by changing the mounting position. Furthermore, instead of just one rod-

like member

33, 34, two or more rod-like members may be attached so as to be stacked, and the resistance force may be changed depending on the number of rod-

like members

33, 34 attached.

Regarding the safety function, if the training equipment is configured to be elastically deformable, either the

annular portions

11 and 12, the connecting portion 13, or the inner continuous portion 14 may deteriorate due to repeated deformation or deterioration due to long-term use. may be damaged. In this case, if the damaged portion separates, there is a possibility that the separated end may come into contact with the user, so a safety feature may be added to prevent separation in the event of breakage. For example, at least a part of the training equipment, such as the

annular parts

11 and 12, is configured by two types of members that are formed separately on the outer peripheral side and the inner side (center side) of the cross section, so that even if the outer part breaks, the inner part It is preferable that the training equipment be continuous so that the training equipment will not be separated even if it is partially damaged. Specifically, a metal spring member that can be easily expanded and contracted is arranged as a core material in the central part of the cross section of the

annular parts

11 and 12, and a cylindrical spring member that is easily expanded and contracted is placed on the outside of the spring member. It may also be configured such that the outer peripheral portion is located.

Additionally, regarding the safety feature, if one side of the training equipment comes off from the stretched state and retracts forcefully, there is a possibility that the training equipment will come into contact with the user. For this reason, a cover member having cushioning properties that is softer than the material of the

annular parts

11 and 12 may be attached or wrapped around a part of the

annular parts

11 and 12. For example, cover members made of spherical urethane foam may be attached to multiple locations on the peripheral edge of the second annular portion 12. Thereby, the cover member absorbs the impact force when the training equipment comes into contact with the user, and the contact force applied to the user can be reduced. In addition, one or more cover members that can be attached to the position of the handle or the position where the foot steps are attached to the

annular parts

11, 12, etc., so that the training equipment can be removed from the hands and feet during exercise. It is also possible to adopt a configuration that can prevent slipping and coming off.

Regarding the usage status confirmation function, an output that can output different information to the

annular parts

11, 12, the connecting part 13, or the inner continuous part 14 before and after gripping and deforming the

annular parts

11, 12 Equipment may be provided. For example, an output device may be configured by combining a strain gauge and a transmitter equipped with a communication function such as Bluetooth (registered trademark), and deformation operations may be counted by another device such as a smartphone. A dedicated program for managing the number of days and frequency of exercise may be installed on a separate device to facilitate the management of the number of training sessions.

Note that a plurality of output devices capable of detecting the deformation of the

annular portions

11 and 12 may be installed for each of the two

annular portions

11 and 12 in order to detect the deformation status of the two

annular portions

11 and 12. It may be configured by attaching it to the location. Further, an output device may be attached to the connecting part 13 to detect the amount of change in angle and the amount of deformation such as distortion with respect to the

annular parts

11 and 12. The deformation can be detected by an output device installed on one coupling part 13.

In addition, regarding the usage status confirmation function, the

annular parts

11 and 12, the connecting part 13, and the inner continuous part 14 are grasped and deformed before and after deforming any or more of the

annular parts

11 and 12, the connecting part 13, and the inner continuous part 14. A marker (mark) whose relative position changes depending on the case may be provided. The marker may be composed of a part that is colored differently from other parts, may be composed of a color with higher saturation than other parts (for example, fluorescent color, etc.), or it may be composed of a part that is colored differently from other parts, or it may be made of a color that is more saturated than other parts (for example, fluorescent color), or it can be made of a part that is colored differently from other parts. The marker may be composed of a light emitting section. By using a camera device that can input image information of the user's exercise status, including the marker, to a management device such as a smartphone or personal computer, it is possible to count the number of deformation operations based on changes in the relative position of the marker. , resistance force can be estimated based on the amount of deformation, and training status can be easily managed with a dedicated application.

For example, in the above embodiment, the

training equipment

10, 20, 30 is provided with two

annular parts

11, 12, but three or more annular parts of different sizes are connected by a connecting part for training. Equipment may also be configured.

In addition, as an exercise using the

training tools

10, 20, and 30, a case where the user performs an exercise to stretch two places along the longitudinal direction or the transverse direction is illustrated, but the exercise in the longitudinal direction and the transverse direction The exercise of stretching the

training tools

10, 20, 30 in a diagonal direction other than the above may be performed, and the movement is not limited to the stretching movement, but also the movement of bringing the gripped parts closer together. Exercises using three or more locations may be performed, such as inserting the feet into two of the four hole sections defined by the and connecting portion 13 and grasping and stretching the section forming the remaining region. .
