Description

The present invention relates to training equipment.

Patent Literature 1 discloses a stretching device in which two spherical bodies are movably fitted to a main body made of braided elastically stretchable string bodies such as rubber. When the string-like main body of this stretching device is pulled up and down, the main body becomes thinner and the spherical body descends. The closer the direction when the body is pulled is to the vertical direction, the faster the spherical body descends. However, as the direction of the main body when pulled is changed from the horizontal direction to the vertical direction, the load felt by the user's body increases. By utilizing this phenomenon and pulling the body closer to the vertical so that the spherical body falls as quickly as possible, the posture and body balance of the user can be naturally straightened.

<Example 1>
A first embodiment embodying the present invention will be described below with reference to FIGS. 1 to 5. FIG. 2 and 3 are defined as upward and downward as they are in the following description.

As shown in FIG. 1, the training apparatus A of Example 1 includes one elongated elastic body 10 and two (plural) movable bodies 20 and 30 . As shown in FIGS. 1 and 3, the long elastic body 10 is made by braiding three rubber cords 11 made of silicone rubber. Therefore, on the outer peripheral surface of the long elastic body 10, there are a plurality of protrusions 12, which are portions of the rubber cord 11 that are bent from the outside to the inside in order to form the braid. When the long elastic body 10 is in a free state without elastic deformation, the plurality of projections 12 are arranged at a constant pitch in both the length direction (axial direction) and the circumferential direction of the long elastic body 10. are arranged as follows.

The cross-sectional shape of each rubber cord 11 of the rubber cord 11 is a perfect circle, and the outer diameter of the rubber cord 11 is constant over the entire length. The outer diameter dimension and length dimension of the three rubber cords 11 are the same. A pair of gripping portions 13 are formed at both ends of the long elastic body 10 by tying the long elastic body 10 in a ring shape. As shown in FIG. 2, the user U of the training device A can elastically stretch the long elastic body 10 (rubber cord 11) by hooking both hands H on the pair of grips 13. As shown in FIG.

In the first embodiment, the outer diameter of one long elastic body 10 is defined as the diameter of an imaginary circle that circumscribes the three rubber cords 11 (projections 12 of the long elastic body 10). In a free state in which the long elastic body 10 is not elastically stretched, there is a gap between the three rubber cords 11 as shown in FIG. That is, in a cross section obtained by cutting the long elastic body 10 perpendicularly to the length direction, there is a gap between the three rubber cords 11 in the free state. When the long elastic body 10 in the free state starts to expand, the three rubber cords 11 elastically expand while approaching each other in the radial direction and the circumferential direction. As the long elastic body 10 elastically expands, the outer diameter of the long elastic body 10 becomes smaller.

The first movable body 20 is made of silicone rubber like the long elastic body 10 (rubber cord 11). The first movable body 20 as a whole has a vertically symmetrical, vertically long tubular shape with its axis directed in the vertical direction. As shown in FIGS. 3 and 4, the first movable body 20 is formed with a first insertion hole 21 penetrating vertically. The cross-sectional shape of the first insertion hole 21 when the first movable body 20 is horizontally cut is a perfect circle. The inner diameter dimension of the first insertion hole 21 is constant over the entire length of the first insertion hole 21 . The inner diameter dimension of the first insertion hole 21 is smaller than the outer diameter dimension of the long elastic body 10 in the free state. The length dimension La in the axial direction (vertical direction) of the first movable body 20 (the first insertion hole 21) is larger than the pitch between two protrusions 12 adjacent to each other in the vertical direction.

The plan view shape and bottom view shape of the first movable body 20 are squares concentric with the first insertion hole 21 . The vertical dimension of the first movable body 20 is larger than the maximum outer diameter dimension of the first movable body 20 (diagonal length of square in plan view). The outer peripheral surface of the first movable body 20 includes two pairs of first planes 22 , two pairs of second planes 23 and four pairs of third planes 24 . The first plane 22 is composed of isosceles triangles, which are vertically symmetrically adjacent to each other and form a pair with a common base. The two pairs of first planes 22 constitute the front and rear surfaces of the first movable body 20 . The second plane 23 is formed of an isosceles trapezoid, and pairs of vertically symmetrically adjacent ones with the bottom bases in common are formed.

The two pairs of second planes 23 constitute left and right side surfaces of the first movable body 20 . The third plane 24 is formed of scalene triangles, and adjacent triangles having a common apex angle form a pair in a vertically symmetrical manner. The four pairs of third planes 24 are arranged so as to intervene between the first plane 22 and the second plane 23 in the circumferential direction. In plan view and bottom view, the upper bases of the two second planes 23 and the bases of the four third planes 24 form a regular hexagon concentric with the first insertion hole 21 .

The second movable body 30 is made of silicone rubber like the long elastic body 10 (rubber cord 11) and the first movable body 20. As shown in FIG. As shown in FIGS. 3 and 5, the second movable body 30 as a whole has a tubular shape with its axis directed vertically. The second movable body 30 is formed with a second insertion hole 31 penetrating vertically. The cross-sectional shape of the second insertion hole 31 when the second movable body 30 is horizontally cut is a perfect circle. The inner diameter dimension of the second insertion hole 31 is constant over the entire length of the second insertion hole 31 . The inner diameter dimension of the second insertion hole 31 is smaller than the outer diameter dimension of the long elastic body 10 in the free state, and the same dimension as the inner diameter dimension of the first insertion hole 21 .

The length dimension Lb in the axial direction (vertical direction) of the second movable body 20 (the second insertion hole 31) is larger than the pitch between the two protrusions 12 adjacent to each other in the vertical direction. smaller than the height dimension La. For example, the length La of the first insertion hole 21 (first movable body 20) is approximately 1.7 times the length Lb of the second insertion hole 31 (second movable body 30). Since the first insertion hole 21 and the second insertion hole 31 have the same inner diameter, the inner peripheral area of the first insertion hole 21 is larger than the inner peripheral area of the second insertion hole 31 . The weight W (volume) of the first movable body 20 is greater than the weight W (volume) of the second movable body 30 . For example, the weight W (volume) of the first movable body 20 is approximately 1.1 to 1.4 times the weight W (volume) of the second movable body 30 .

The outer peripheral surface of the second movable body 30 is composed of two upper and lower polyhedral portions 33 . The upper polyhedral portion 33 has a form in which five polygonal faces 34 formed of regular pentagons of the same size are arranged adjacent to each other in the circumferential direction and connected over the entire circumference. The lower polyhedral portion 33 also has a configuration in which five polygonal faces 34 of regular pentagons of the same size are adjacent to each other in the circumferential direction and connected over the entire circumference. The upper polygonal surface 34 and the lower polygonal surface 34 are adjacent to each other with a positional relationship shifted by half a pitch in the circumferential direction. The sides forming the upper edge or the lower edge of the second movable body 30 in each polygonal surface 34 form a regular pentagon concentric with the second insertion hole 31 when the second movable body 30 is viewed from the front and bottom.

When the long elastic body 10 is in a free state in which it is not elastically stretched, the outer diameter of the long elastic body 10 is larger than the inner diameter of the first insertion hole 21 . The elastic body 10 is elastically contracted in diameter. Therefore, due to the radially outward elastic restoring force of the long elastic body 10 , a gap between the outer periphery (projection 12 ) of the long elastic body 10 and the inner peripheral surface of the first insertion hole 21 is formed. A frictional force F is generated by an elastic restoring force of 10. Since the frictional force F at this time is larger than the weight W of the first movable body 20, the first movable body 20 does not descend even if the elongated elastic body 10 is directed vertically by its own weight. Similarly, when the long elastic body 10 is in the free state, the second movable body 30 also does not descend.

When the long elastic body 10 is elastically stretched, the outer diameter of the long elastic body 10 gradually decreases. Power is getting smaller. Therefore, when the long elastic body 10 is extended to a predetermined length, the frictional force F between the long elastic body 10 and the first insertion hole 21 (first movable body 20 ) increases to the weight W of the first movable body 20 . , the first movable body 20 starts to descend. Similarly to the first movable body 20, the second movable body 30 also starts to descend when the long elastic body 10 extends to a predetermined length.

As described above, the timing at which the first movable body 20 and the second movable body 30 start to descend during the elongation process of the long elastic body 10 depends on the weight W of each movable body 20 and 30 and the weight W of each movable body 20 and 30. It is determined by the magnitude relationship with the frictional force F generated between the long elastic body 10 and the elastic body 10 . The frictional force F is determined by the coefficient of friction μ between the long elastic body 10 and the movable bodies 20 and 30 and the radially outward drag force R caused by the elastic restoring force of the long elastic body 10. = μ·R. The coefficient of friction μ is determined by the relationship between the material of the long elastic body 10 and the materials of the movable bodies 20 and 30 .

The drag force R of the long elastic body 10 is the radially outward pressure P caused by the extension amount of the long elastic body 10 (the outer diameter of the long elastic body 10) and the inner circumference of each insertion hole 21, 31. It depends on the contact area S (the length dimensions La and Lb and the inner diameter dimensions of the insertion holes 21 and 31) with the long elastic body 10 at . Which of the first movable body 20 and the second movable body 30 starts to descend first is determined according to the magnitude relationship of these parameters. Depending on the parameter settings, the first movable body 20 and the second movable body 30 may start descending at the same timing.

In the case of the training device A of the first embodiment, the inner diameters of the first insertion hole 21 and the second insertion hole 31 are the same size, but the number of protrusions 12 elastically contacting the inner peripheral surface of the first insertion hole 21 is , more than the number of protrusions 12 elastically contacting the inner peripheral surface of the second insertion hole 31 . Therefore, when the long elastic body 10 is elastically stretched, the frictional force F generated in the first movable body 20 becomes larger than the frictional force F in the second movable body 30 regardless of the length of the stretched length. The frictional force F is proportional to the number of protrusions 12 elastically contacting the inner peripheral surfaces of the insertion holes 21 and 31, and the number of protrusions 12 elastically contacting the inner peripheral surfaces of the insertion holes 21 and 31 is approximately equal to each. It is proportional to the length dimensions La and Lb (inner peripheral areas) of the insertion holes 21 and 31 . Therefore, the frictional force F generated in the first insertion hole 21 is approximately 1.7 times the frictional force F generated in the second insertion hole 31 .

On the other hand, the weight W of the first movable body 20 is larger than that of the second movable body 30, and the ratio of the weight W of the first movable body 20 to the weight W of the second movable body 30 is about 1.1 to 1.1. 4. The ratio of the weight W between the first movable body 20 and the second movable body 30 is obtained from the value of the ratio of the frictional force F generated in the first movable body 20 and the frictional force F generated in the second movable body 30 (approximately 1.7). is also small. Therefore, the second movable body 30 starts to descend earlier than the first movable body 20 .

In the first embodiment, not only the weight W of the first movable body 20 and the weight W of the second movable body 30 are different, but also the friction generated in the first movable body 20 when the long elastic body 10 is in the free state. The force F and the frictional force F generated in the second movable body 30 are also different. The ratio of the weight W to the frictional force F generated when the long elastic body 10 is in the free state is different between the first movable body 20 and the second movable body 30 . As a result, in the process of elongating the long elastic body 10, the timing of the start of descent of the first movable body 20 and the start of descent of the second movable body 30 are different.

Moreover, the descending speeds of the movable bodies 20 and 30 after the first movable body 20 and the second movable body 30 start to descend are different from each other. When the movable bodies 20 and 30 descend, the movable bodies 20 and 30 are slightly tilted with respect to the axis of the long elastic body 10, and the lower sides of the insertion holes 21 and 31 of the movable bodies 20 and 30 are moved downward. is hooked on the protrusion 12 once. Immediately after that, the postures of the movable bodies 20 and 30 are tilted in another direction, so that they pass through the protrusion 12 and are caught by another protrusion 12, and this operation is repeated.

At this time, the larger the lengths La and Lb of the insertion holes 21 and 31 are, the smaller the inclination angles of the movable bodies 20 and 30 are. The smaller the margin of engagement with the protrusion 12, the shorter the time required for each movable body 20, 30 to change its posture and pass through the protrusion 12.例文帳に追加Therefore, in the training device A of the first embodiment, the first movable body 20 having a large vertical dimension descends faster than the second movable body 30 .

Next, a training method using the training device A of the first embodiment will be described. Gripping portions 13 at both ends of the long elastic body 10 are grasped with both hands H, and the training device A is positioned to the side of the user U (see FIG. 2) or to the front of the user U. Extend both arms A. In this state, by extending both arms A in the vertical direction, the long elastic body 10 is elastically deformed so as to extend in the vertical direction. Since the movement of extending both arms A and opening them wide in the vertical direction is rarely performed in daily life, the range of motion of the shoulder joints and elbow joints can be expanded. When you move the joint a lot, the muscles connected to the joint expand and contract greatly, so you can get a stretching effect that stretches and loosens the muscle group that has become stiff. In addition, as the long elastic body 10 elastically expands, the elastic restoring force accumulated in the long elastic body 10 increases, so the load acting on the user U increases. This makes it possible to strengthen the muscle strength of the upper body (arm A, shoulders, chest, back, abdomen, etc.).

At this time, it is desirable to apply an appropriate load according to the user's U physical strength, training goal, and the like. Therefore, the user U selects one of the movable bodies 20 and 30 from the first movable body 20 and the second movable body 30 . For example, when it is desired to reduce the load, the long elastic body 10 is stretched with the second movable body 30 having an early descent start timing positioned below the first movable body 20 . Then, the second movable body 30 starts to descend when the amount of extension of the long elastic body 10 is relatively small, that is, when the load is small. Therefore, by using the timing at which the second movable body 30 starts to descend as a guide, the arm A can be trained with a relatively small load.

Further, when it is desired to increase the load, the long elastic body 10 is stretched with the first movable body 20 having a later descent start timing positioned below the second movable body 30 . Then, the descent of the first movable body 20 is not started until the amount of elongation of the long elastic body 10 becomes relatively large, that is, until the load becomes large to some extent. Therefore, by using the timing at which the first movable body 20 starts to descend as a guide, the arm A can be trained with a relatively large load. As described above, by using the training apparatus A of the first embodiment, it is possible to perform training in which the magnitude of the load is changed according to the physical strength of the user U and the training target.

As another training method using the training apparatus A of the first embodiment, endurance can be increased by maintaining the long elastic body 10 in a stretched state. The first movable body 20 with a fast descent speed has a relatively short descent time required from the start of the descent to the end of the descent. Therefore, by using the required time for lowering the first movable body 20 as a measure of the time required to maintain the extended state of the long elastic body 10, it is possible to increase the endurance of the arm A with a relatively light load.

In addition, the second movable body 30 having a slow descent speed has a relatively long descent time required from the start of the descent to the end of the descent. Therefore, if the time required for the second movable body 30 to descend is used as a measure of the time required to maintain the extended state of the long elastic body 10, it is possible to increase the endurance of the arm A with a relatively strong load. As described above, by using the training apparatus A of the first embodiment, it is possible to perform training for increasing endurance in accordance with the physical strength of the user U and the training target.

The training device A of the first embodiment includes a long elastic body 10 that can be elastically deformed in a form that reduces its diameter as it expands, and an external body that allows the long elastic body 10 to move in the longitudinal direction. It has a first movable body 20 and a second movable body 30 that are fitted together. In a free state in which the elongated elastic body 10 is not elastically deformed, the movement of the first movable body 20 and the second movable body 30 is restricted by friction between the elongated elastic body 10 . The training equipment A of the present embodiment 1 can select a plurality of modes of use according to the user's U physical strength and training goals.

That is, the timing at which the first movable body 20 and the second movable body 30 start to descend in the process of extending the long elastic body 10 in the vertical direction depends on the timing of the first movable body 20 and the second movable body 30. are different from each other. According to the vertical arrangement order of the first movable body 20 and the second movable body 30 when the long elastic body 10 is stretched with both hands H in the vertical direction and the extension amount of the long elastic body 10, the The descent modes of the first movable body 20 and the second movable body 30 are changed. Therefore, by selecting the arrangement order of both movable bodies 20 and 30 and using the descent form of both movable bodies 20 and 30 as a guide, it is possible to apply a suitable load according to the user's physical strength and training target. .

In addition, the descent speed of the first movable body 20 and the second movable body 30 when the long elastic body 10 is vertically extended to a predetermined length is there is a difference between Accordingly, when the long elastic body 10 is extended to a predetermined length, the time required for the first movable body 20 to descend and the time required for the second movable body 30 to descend are different from each other. When performing training to maintain the long elastic body 10 in a stretched state, one of the movable bodies 20 and 30 is selected according to the physical strength of the user U and the training target, and the selected movable body 20 and 30 is lowered. The required time can be used as a measure of the extension maintenance time of the long elastic body 10 .

The configuration for differentiating the descent speeds of the first movable body 20 and the second movable body 30 is as follows. A plurality of protrusions 12 are provided on the outer periphery of the long elastic body 10 so as to be aligned in the longitudinal direction of the long elastic body 10 . The first movable body 20 and the second movable body 30 have different length dimensions La and Lb in the axial direction of the long elastic body 10 . In the process of lowering the movable bodies 20 and 30, the movable bodies 20 and 30 slightly tilt their postures to catch on the protrusions 12, and then tilt their postures in different directions to separate from the protrusions 12, which is repeated. At this time, since the inclination angle of the first movable body 20 having a large length dimension La is smaller than that of the second movable body 30 having a small length dimension Lb, the descending speed of the first movable body 20 having a large length dimension La is is faster than the second movable body 30 having a small length dimension Lb.
