Description

    The present invention is a training tool that obtains a load by a force by which an elastic member expands and contracts and strengthens muscles of the body.

In recent years, the necessity of exercise for maintaining health has been screamed, and the number of people who use sports gyms is increasing. In gyms and the like, various devices for training muscles are prepared for each part of the body, and a great training effect can be obtained, but it is necessary to go to that place and the cost is also expensive.
On the other hand, as a simple training tool that can be used easily at home, not in a gym or the like, an elastic member such as rubber or a spring is used, and training is performed with the force of expansion and contraction of the elastic member as a load. There are many things to do.
For example, Patent Literature 1 discloses a gymnastic instrument using an elastic band provided with a means for adjusting a load that adjusts the length of the band.
For example, Patent Literature 2 discloses a soft expander health device that is formed of only a soft material and avoids an accident during use without using a hard material such as metal or plastic.
For example, Patent Document 3 discloses an elastic rope of a fitness apparatus that is easy to carry by connecting a plurality of ring-shaped elastic units.
For example, Patent Document 4 discloses an exercise tool using a tube made of an elastic material such as rubber.
Such a training tool is suitable for carrying out casually at home every day, and there is a demand for a tool that has a higher effect even when used in such a case.

A basic configuration of the training tool of the present invention will be described.
The training tool of the present invention has a first stretchable member and a second stretchable member that is longer in the longitudinal direction than the first stretchable member, and includes a joint portion that joins both ends thereof. It is a configuration. The training tool of the present invention can obtain a training effect by, for example, holding joints with both hands and obtaining a load due to expansion and contraction of the elastic member when pulled up and down or left and right.
The first stretchable member gives a load to the user from the start of use of the present invention until it reaches the length of the second stretchable member after starting to stretch.
Since the second stretchable member is longer in the longitudinal direction than the first stretchable member, the first stretchable member exceeds the length of the second stretchable member from the first stretchable member. The elastic member overlaps with the load applied to the user and gives a load.
At this time, the 1st and 2nd elastic member may be comprised by one member, and may be comprised by the some member. Furthermore, you may be comprised with the several member from which length differs.
Embodiments of the present invention will be described in detail with reference to the drawings as follows. However, in the following examples, the first elastic member is shown as the elastic member 1, and the second elastic member is shown as the elastic member 2.

Example 1 shows a case where, for example, the first stretchable member (stretchable member 1) and the second stretchable member (stretchable member 2) are each configured by using one belt-like rubber band. .
FIG. 1 is an external view showing a configuration of a training tool according to Embodiment 1 of the present invention. The training tool 100 includes a stretchable member 1 using a belt-like rubber band and a stretchable member 2, and both ends are joined at joints 10. The stretchable member 2 is longer than the stretchable member 1. It is.
Here, the shape of the elastic members 1 and 2 is not limited to a belt shape, but may be a string shape, a rope shape, a tube shape, or a coil shape. Different shapes and widths may be used. The material may be not only an elastomer material (synthetic rubber, natural rubber or thermoplastic elastomer), but also a fiber containing elastic fibers such as polyurethane, or a metal (coiled). The elastic member 1 and the elastic member Each of 2 may be a different material.
When using the training tool 100, for example, the user holds both ends 10 with his / her left and right hands as shown in FIG. I do. At this time, how the load of the training tool 100 acts on the user will be described with reference to FIG.
FIG. 2 shows a view of the training tool 100 of FIG. 1 viewed from the direction A in FIG.
FIG. 2A shows a state immediately before holding the both ends of the training tool 100 of the present invention by hand and pulling it in the opposite direction, and shows a state where no load is applied to the user. If the length of the elastic member 1 at this time is x1, and the length of the elastic member 2 is x2, then x1 <x2.
FIG. 2B shows a state immediately after holding both ends of the training tool 100 by hand and starting to pull in the opposite direction (hereinafter referred to as initial movement), and the user is under a load during the initial movement. Show. At this time, as compared with the state of FIG. 2A, the elastic member 1 is in a state where the length is slightly extended, and the elastic member 2 is not changed in length. When the length of the elastic member 1 at the time of the initial movement is x1-1, the relationship x1 <x1-1 <x2 is established.
That is, at the time of initial movement, the user is subjected to a load that is generated when only the stretchable member 1 is pulled.
FIG. 2C shows a state in which the use of the training tool 100 is started and then pulled in the opposite direction (hereinafter referred to as the middle stage), and the user begins to receive a strong load exceeding the initial load. ing. At this time, the length of the stretchable member 1 is further extended as compared with the state of FIG. 2B, and is in a state extended to the same length as the stretchable member 2. When the length of the elastic member 1 at the middle stage is x1-2, the relationship x1 <x1-1 <x1-2 = x2 holds.
That is, during the middle stage, the user begins to receive a load generated by pulling both the elastic member 1 and the elastic member 2 from a load generated by only the elastic member 1 being pulled.
Thereafter, when the training tool 100 is further pulled in the opposite direction from the middle stage (hereinafter, at the end stage), the user is loaded with both the stretchable member 1 and the stretchable member 2. It becomes. At this time, the stretchable member 1 and the stretchable member 2 are in a state of extending longer than the length x2 in a state where the stretchable member 2 is not loaded.
That is, a strong load generated by pulling both the elastic member 1 and the elastic member 2 continues to be applied to the user at the end of the game.

In Example 2, for example, the first stretchable member (stretchable member 1) is one strip-shaped rubber band, and the second stretchable member (stretchable member 2) is two strip-shaped rubbers having different lengths. The case where it comprises using a band (elastic member 2A and 2B) is shown.
FIG. 3 is an external view showing a configuration of a training tool according to the second embodiment of the present invention. The training tool 110 joins the stretchable member 1, the stretchable member 2A, and the stretchable member 2B using a belt-like rubber band at the joint portion 10, and the stretchable member 1 has the shortest length in the longitudinal direction. The elastic member 2A and the elastic member 2B are long in this order. Here, the shape of the elastic members 1 to 2B is not limited to the belt shape, but may be a string shape, a rope shape, a tube shape, or a coil shape, and each of the elastic members 1 to 2B has a different shape or It may be a width. The material may be not only an elastomer material (synthetic rubber, natural rubber or thermoplastic elastomer), but also a fiber containing elastic fibers such as polyurethane, or a metal (coiled), and each of the elastic members 1 to 2B. May be of different materials.
Next, how the load of the training tool 110 acts on the user will be described with reference to FIG.
FIG. 4 shows a view of the training tool 110 of FIG. 3 as viewed from the direction A of FIG.
FIG. 4A shows a state immediately before holding the training tool 110 of the present invention with both hands and pulling it in the opposite direction, and shows a state where no load is applied to the user.
When the length of the elastic member 1 at this time is x1, the length of the elastic member 2A is x2A, and the length of the elastic member 2B is x2B, x1 <x2A <x2B.
FIG. 4B shows a state in which the training tool 110 is started to be used and pulled further in the left and right direction, and a load is applied to the user.
At this time, the length of the elastic member 1 is extended as compared with the state of FIG. 4A, and the elastic member 2B is extended to the same length as the elastic member 2A. There is no change. When the length of the elastic member 1 at this time is x1-1, the relationship x1 <x2A = x1-1 <x2B holds.
In other words, the user starts to be subjected to a load caused by pulling both the elastic member 1 and the elastic member 2A.
FIG. 4C shows a state in which the use of the training tool 110 is started and is further pulled in the opposite direction, and a further heavy load is applied to the user.
At this time, compared with the state of FIG.4 (b), the length of the elastic members 1 and 2A is the further extended state, and is the state extended to the same length as the elastic member 2B. When the length of the elastic member 1 at this time is x1-2 and the length of the elastic member 2A is x2A-1, the relationship of x1 <x2A = x1-1 <x1-2 = x2A-1 = x2B is established. It is true.
That is, the user begins to be subjected to a load generated by pulling all the elastic members 1 to 2B.
In a state where the training tool 110 is further pulled in the left and right direction after this, the user is in a state where all the loads of the elastic members 1 to 3 are applied. At this time, the elastic members 1 to 2B are in a state of extending longer than the length x2B in a state where the elastic member 2B is not loaded.
That is, a strong load generated by pulling all of the elastic members 1 to 2B is continuously applied to the user.
As described above, the training tool 110 is subjected only to a load on the stretchable member 1 in the initial movement when the user starts training, and the stretchability after the length of the stretchable member 1 exceeds the length of the stretchable member 2A. It seems that both the members 1 and 2A are loaded, and all the loads of the stretchable members 1 to 2B are applied after the length of the stretchable member 1 and the stretchable member 2A exceeds the length of the stretchable member 2B. Moreover, the magnitude of the load can be switched strongly in a stepwise manner during use. At this time, it is also possible to adjust the timing for strongly switching the magnitude of the load according to the lengths of the elastic member 2A and the elastic member 2B.
Furthermore, as the number of elastic members having different lengths increases, it is natural that the strength of the load and the number of steps for switching the load can be increased.

Example 3 shows a case where four training tools of Example 1 are provided as one unit, and each unit is connected in series in the longitudinal direction.
FIG. 5 is an external view showing a configuration of a training tool according to Embodiment 3 of the present invention. The training tool 200 includes a stretchable member 1 and a stretchable member 2 using a belt-shaped rubber band, and both ends are joined by a joint 10, and the stretchable member 1 is further provided at three locations other than the both ends joint 10. The elastic member 2 is longer than the elastic member 1.
Here, the shape of the elastic members 1 and 2 is not limited to the belt shape, but may be a string shape, a rope shape, a tube shape, or a coil shape. May be different. Further, the material may be not only an elastomer material (synthetic rubber, natural rubber or thermoplastic elastomer), but also a fiber containing elastic fibers such as polyurethane, or a metal (coiled). The materials may be different. Further, the three joint portions 11 are arranged at equal intervals for convenience of explanation, but may be arbitrary positions. In this case, the length x10 between the joints is naturally different.
When using the training tool 200, for example, the user holds both ends of the training tool 200 with his left and right hands as shown in FIG. Do training. At this time, how the load of the training tool 200 acts on the user will be described with reference to FIGS. 2 and 7.
FIG. 7A shows a state immediately before the user holds both ends of the training tool 200 with his / her hand and pulls it in the opposite direction, and shows a situation in which no load is applied to the user. This corresponds to the state of a).
FIG. 7 (b) shows a state where the user holds both ends of the training tool 200 with his / her hand and pulls it in the opposite direction, and shows a situation where the user is under load, FIG. 2 (b). Corresponds to the state of
FIG. 7C shows a state where the user holds both ends of the training tool 200 with his / her hand and pulls it to the limit in the left / right direction, and the user is under maximum load. This corresponds to the state of FIG.
From this, it can be seen that the training tool 200 of FIG. 5 operates in the same manner as the training tool 100 of FIG.
The training tool 200 includes a stretchable member 1 and a stretchable member 2 using a belt-like rubber band, and both ends are joined at a joint 10, and the joint 11 is provided at three locations other than the both ends joint 10. The stretchable member 2 has been described as having a longer configuration than the stretchable member 1, but the training tool 100 in FIG. A plurality of training tools 110 may be connected in series as one unit.
FIG. 8 is a diagram in which exercise is carried out by changing the parts of the training tool 200 held by hand. 8 (a) to 8 (c) are examples of training in which both ends of the training tool 200 are held by the left and right hands and pulled in the opposite directions. FIGS. 8 (a ') to (c') This is an example of training in which the training tool 200 is held through the left and right hands on the wheel and pulled in the opposite direction.
FIG. 8A and FIG. 8A ′ show a state immediately before the user holds the training tool 200 by hand and pulls it in the opposite direction, and shows a situation in which no load is applied to the user. Yes. At this time, when the width x100 of both hands in FIG. 8A and the width x200 of both hands in FIG. 8A ′ are set, x100> x200.
FIG. 8B shows a state where the user holds the training tool 200 with his / her hand and pulls it in the opposite direction. Only the stretchable member 1 is stretched and the stretchable member 2 is loosened. At this time, a situation is shown in which a load obtained by pulling only the stretchable member 1 is applied to the user. At this time, the width of both hands of the user is open to the same width as in FIG.
FIG. 8B 'shows a state where the user holds the training tool 200 with his / her hand and pulls it to the limit in the left / right direction, and both the elastic member 1 and the elastic member 2 are extended. . At this time, a situation is shown in which the maximum load obtained by pulling both the elastic member 1 and the elastic member 2 is applied to the user. At this time, when the width of both hands in FIG. 8B is x100-1 and the width of both hands in FIG. 8B ′ is x200-1, x100-1 = x200-1.
FIG. 8C shows a state in which the user holds the training tool 200 with his / her hand and pulls it to the limit in the left-right direction, and both the stretchable member 1 and the stretchable member 2 are stretched. At this time, a situation is shown in which the maximum load obtained by pulling both the elastic member 1 and the elastic member 2 is applied to the user. FIG. 8 (c ′) shows a state where the user holds the training tool 200 with his hand and pulls it to the limit in the left-right direction, and both the stretchable member 1 and the stretchable member 2 are stretched. . At this time, a situation is shown in which the maximum load obtained by pulling both the elastic member 1 and the elastic member 2 is applied to the user. At this time, since the user is already holding the training tool 200 in the state shown in FIG. 8 (b ′) and pulling the training tool 200 to the limit in the left / right direction, the state shown in FIG. 8 (b ′) The diagram of FIG. 8 (c ′) is the same. At this time, when the width of both hands in FIG. 8C is x100-2 and the width of both hands in FIG. 8C ′ is x200-2, x100-2> x200-2.
From this, the training tool 200 has different exercise start and end positions and the maximum extension width of the training tool depending on the position where the training tool is held. Due to these differences, the position where the load of only the stretchable member 1 and the load of both the stretchable member 1 and the load of the stretchable member 2 are switched in stages during the exercise, and the extension width and the stretch that the load of only the stretchable member 1 is applied The stretch widths to which both the elastic member 1 and the stretchable member 2 are applied are different.
That is, the training tool 200 can adjust the position of the training tool according to the user's physique, strength, and desired load.
Moreover, the training tool 200 may include a configuration in which the training tools 100 and 110 are connected in series as one unit. With this configuration, the number of stages for switching the load can be increased.
Further, when the training tool 200 has a configuration in which the training tool 100 is connected in series as a single unit, the difference in length between the elastic member 1 and the elastic member 2 in each unit is changed for each unit. The switching timing of the load between the respective joints is different, and the number of stages for switching the load can be further increased. At this time, if the unit includes the training tool 110, the number of stages for switching the load can be further increased by changing the lengths of the elastic member 2A and the elastic member 2B for each unit.
Thus, it becomes possible to adjust the load of the training tool 200 more delicately by changing the configuration of the elastic member for each unit.

Example 4 shows a case where three training tools of Example 1 are provided as one unit, each is connected in series in the longitudinal direction, and a connection member 3 is provided between the units. These are the external views which show the structure of the training tool concerning Example 4 of this invention. The training tool 300 includes the elastic member 1 using the belt-shaped rubber band shown in Example 1 and the elastic member 2 longer than the elastic member 1, and the training tool 100 having both ends joined at the joint portion 10, In this configuration, three training tools 100 and two joining members 3 are provided, and the training tools 100 and joining members 3 using elastic band-like rubber bands are connected alternately and in series. Here, for convenience, the elastic member 1 and the elastic member 2 have the same tensile elastic modulus, and the joining member 3 has a tensile elastic modulus twice that of the elastic member 1 and the elastic member 2. Furthermore, it is assumed that the length at the time when the load of the elastic member 1 and the joining member 3 is not applied is the same.
Here, since the properties of the stretchable member 1 and the stretchable member 2 are as described above, they will be omitted, and the properties of the joining member 3 will be described. The joining member 3 is a member different from the stretchable member 1 and the stretchable member 2 that are joined in series in the longitudinal direction to the joint portion between the ends of the stretchable member 1 and the stretchable member 2, and may or may not be stretchable. . The shape of the joining member 3 may be any shape, and the shape and width of each joining member 3 may be different. The material may be any material, and each material of the joining member 3 may be different. Moreover, although the ratio of the length of the elastic member 1 and the elastic member 2 and the length of the joining member 3 are made the same for convenience, it may be set to an arbitrary ratio and length. In this case, it is natural that the lengths x1 and x3 between the joints are different from each other.
Here, when the training tool 300 for explaining how the load of the training tool 300 acts on the user is pulled in the opposite direction, the lengths of the elastic member 1 and the elastic member 2 are the same from the initial movement. In the meantime, the elastic member 1 having a smaller elastic modulus than the bonding member 3 extends larger than the bonding member 3, but the bonding member 3 having a larger elastic modulus than the elastic member 1 is compared with the elastic member 1. It is clear that the elongation becomes smaller. Thereafter, since the stretchable member 1 and the stretchable member 2 are pulled at the same time in the training tool 100, the tensile elastic modulus of the training tool 100 and the joining member 3 are the same, and it is natural that they will be stretched at the same ratio. is there.
Here, when only the training tool 100 is joined in the longitudinal direction and the length of the training tool 300 is compared, the length is the same when no load is applied. When the elastic member 1 and the elastic member 2 are pulled in opposite directions until the lengths of the elastic member 1 and the elastic member 2 are the same, the training tool 100 having the elastic member 1 having a small tensile elastic modulus in series is arranged in five in the longitudinal direction. Of course, the joint is longer than the training tool 300. Thereafter, since the elastic member 1 and the elastic member 2 are pulled simultaneously in the training tool 100, the tensile elastic modulus of the training tool 100 and the joining member 3 is the same, and only five training tools 100 are joined continuously in the longitudinal direction. Of course, the training tool 300 will grow at the same rate.
From this, the user can combine the training tool 100 and the joining member 3 to obtain the exercise effect of the added strength obtained by the stretching force of the stretchable member 2 at a shorter stretch distance than that using only the training tool 100. Can be obtained.
In addition, the configuration of the training tool 300 includes three training tools 100 and two joining members 3 using elastic rubber bands, and the training tools 100 and the joining members 3 are alternately connected in series. The stretchable member 1, the stretchable member 2, and the joining member 3 have the same tensile elastic modulus, and the length when the load on the stretchable member 1 and the joining member 3 is not applied is the same. In the case of, it will be described how the training tool 300 acts on the user.
From the initial movement until the lengths of the elastic member 1 and the elastic member 2 become the same, it is clear that the elastic member 1 and the joining member 3 extend in the same manner because of the same elastic modulus. Thereafter, in the training tool 100, the stretchable member 1 and the stretchable member 2 are pulled simultaneously, so that the tensile elastic modulus is twice that of the joining member 3, and the training tool 100 is naturally less stretched than the joining member 3. It is.
Here, when only the training tool 100 is joined in the longitudinal direction and the length of the training tool 300 is compared, the length is the same when no load is applied. When the stretchable member 1 and the stretchable member 2 are pulled in opposite directions until the lengths of the stretchable member 1 and the stretchable member 2 are the same, the stretchable elastic modulus of the stretchable member 1 and the joining member 3 is the same. It is natural that the length of the training tool 300 is the same as that obtained by joining the five consecutively. Thereafter, since the stretchable member 1 and the stretchable member 2 are pulled simultaneously in the training tool 100, the stretchable elastic modulus of the training tool 100 is double the stretchable elastic modulus of the joining member 3, and the joining member 3 is more than the training tool 100. Naturally, since only five training tools 100 are joined in the longitudinal direction in a continuous manner, the elongation is smaller than that of the training tool 300.
In this case, the user combines the training tool 100 and the joining member 3 so that the stretchable member 1 and the joining member 3 have the same length as the stretchable member 2 from those using only the training tool 100. A strong load can be obtained while extending greatly.
Also, the training tool 300 configuration. Three training tools 100 and two plate-like plastic joint members 3 that are not stretchable are provided, and the training rule 100 and the joint safety A3 are alternately and in series, the stretchable member 1 and the stretchable member. 2 are the same tensile elastic modulus, and the length of the stretchable member 1 and the joining member 3 at the time when no load is applied is the same configuration, the training tool 300 gives the user how to Explain how it works.
From the initial movement until the lengths of the stretchable member 1 and the stretchable member 2 become the same, it is clear that only the stretchable member 1 extends, and the non-stretchable joining member 3 does not stretch. . Thereafter, in the training tool 100, the stretchable member 1 and the stretchable member 2 are pulled simultaneously, so that the tensile elastic modulus is twice that of the stretchable member 1 alone, but the non-stretchable joining member 3 extends. It is clear that only the load obtained by pulling only the training tool 100 is applied.
Here, when only the training tool 100 is joined in the longitudinal direction and the length of the training tool 300 is compared, the length is the same when no load is applied. When the stretchable member 1 and the stretchable member 2 are pulled in opposite directions until the length is the same, the joining member 3 is not stretchable, so that only the training tool 100 is joined continuously in the longitudinal direction. Naturally, the length is longer than the length of the training tool 300. Thereafter, since the stretchable member 1 and the stretchable member 2 are pulled simultaneously in the training tool 100, the stretch of the training tool 100 in which only five training tools 100 are joined in the longitudinal direction is larger than that of the training tool 300. Of course.
From this, the user can combine the training tool 100 and the joining member 3 to obtain the exercise effect of the added strength obtained by the stretching force of the stretchable member 2 at a shorter stretch distance than that using only the training tool 100. Can be obtained.
In addition, when the training tool 300 has a configuration in which the training tool 100 is a single unit and the joining member 3 are connected in series, the difference in length between the stretchable member 1 and the stretchable member 2 in each unit is calculated. By changing each unit, changing the length of the joining member 3, or changing the elastic modulus of elasticity of each of the elastic members and the joining member 3, the timing of switching the load between the joints will be different. In addition, the number of stages for switching loads can be increased. At this time, if the configuration includes the training tool 110, the number of stages for switching loads can be further increased by changing the lengths and elastic modulus of the elastic members 2A and 2B for each unit.
Thus, by changing the configuration of the elastic member for each unit or for each joining member 3, it is possible to adjust the timing for switching various loads.

Further, FIGS. 10-14 teach how to perform training using the training tool of the present invention.
FIG. 10 shows a state in which training is performed by pulling the training tool with both hands in opposite directions. The training tool shown in FIG. 10 uses a rubber band longer than the elastic member 1 and the elastic member 2 of the training tool 200 of Example 3 to increase the number of joints 11. FIG. 10 (a) corresponds to FIG. 7 (a), and FIG. 10 (b) shows a state corresponding to FIG. 7 (c). At this time, the length of the tool can be changed by changing the positions of the left and right hands, and the load applied during training can be adjusted.
FIG. 11 shows a motion of pulling two poles through the training tool in the opposite direction using the training tool of FIG.
FIG. 12 shows an exercise in which a training tool is passed through the ankle while sitting on a chair and the foot is opened in the opposite direction.
FIG. 13 shows an exercise in which the training tool is put on the foot and the leg is pulled in the opposite direction.
FIG. 14 shows the exercise of pulling the training tool while crossing the arms in the opposite direction from the back to the front.
As described above, in addition to pulling in the opposite direction by hand, it is possible to cope with various exercises such as exercises using tools and exercises using feet.
