Description

[Technical field]

[0001] The present invention relates to a wearable training device. [Background technology]

[0002] In modern times, chronic lack of exercise and walking has led to a decline in muscle strength and various associated problems. In order to maintain muscle strength, it is necessary to apply an appropriate load to the muscles on a daily basis, but in modern life, the muscles involved in walking are often not loaded sufficiently, which results in a decline in lower limb muscle strength with age, which leads to a decline in walking function and the onset of various diseases.

[0003] For example, among the lower limb muscles, weakness is particularly problematic for the iliopsoas and adductor muscles. Both are large muscles involved in hip joint movement, with the iliopsoas contributing greatly to hip joint flexion and the adductor muscles contributing greatly to hip joint adduction. They are antagonistic to the gluteal muscles, but compared to the gluteal muscles, which are used more frequently in daily life, they tend to be weaker. Of these, weakness in the iliopsoas leads to a decrease in stride length, which is the main cause of impaired walking function, and weakness in the adductor muscles can induce external rotation of the hip joint while walking (the so-called "bow-legged" posture).

[0004] Conventionally, there are known training devices that can effectively apply a load to the iliopsoas muscle and can effectively train the iliopsoas muscle for people of all ages, from children to the elderly, and even for athletes. For example, Patent Document 1 describes a training device that includes a first mounting part that is attached at least above the greater trochanter, a second mounting part that is fixed to the thigh, and a load generating means that is placed between the first mounting part and the second mounting part, and that is characterized in that the load generating means applies a load when the leg is lowered forward.

[0005] [Patent Document 1] JP 2020-81305 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, while the training device described in Patent Document 1 is capable of effectively training the iliopsoas muscle, it has a problem in that it is not capable of selectively training the adductor muscles.

[0007] The present invention has been made in consideration of the above problems, and has as its main object to provide a wearable training device that can selectively train the adductor muscles. [Means for solving the problem]

[0008] In order to achieve at least one of the above objects, the present invention employs the following means.

[0009] The wearable training device of the present invention comprises: A wearable training device that is worn and used by a wearer, A waist attachment part that is attached to the waist of the wearer; A leg attachment part to be attached to the leg of the wearer; an arm portion that rotatably connects the waist attachment portion and the leg attachment portion; a load generating unit that generates a load in a lateral direction on the leg of the wearer when the arm unit rotates; The present invention is characterized in that it comprises It is something.

[0010] This wearable training device includes a waist attachment part that is attached to the waist of the wearer and a leg attachment part that is attached to the legs of the wearer, and the waist attachment part and the leg attachment part are rotatably connected by an arm part, so that the arm part rotates when the wearer walks or runs. At this time, a load generating part is provided that generates a load in the lateral direction of the wearer as the arm part rotates, so that a load is generated in the lateral direction of the wearer as the arm part rotates. In this way, a load can be selectively applied to the adductor muscles, and the adductor muscles can be selectively trained.

[0011] In the wearable training device of the present invention, the load generating unit may generate loads in the forward and lateral directions of the wearer when the wearer wears the device. This allows a load to be applied to the iliopsoas muscle in addition to the adductor muscles, thereby reducing the decline in lower limb muscle strength and preventing a decline in walking function.

[0012] In the wearable training device of the present invention, the load generating unit may generate a load when the wearer's legs are positioned backward. Since it is known that the adductor muscles are more active when the legs are positioned backward during walking, the adductor muscles can be trained efficiently by generating a load when the legs are positioned backward.

[0013] In the wearable training device of the present invention, the load generated by the load generating unit may be maximum when the hip joint angle of the wearer is between -10° and -20°. It is known that the load on the adductor muscles is effective when the hip joint angle of the wearer is between 0° and -30°, and more effective when it is between -10° and -20°. By applying the load at this angle, it is possible to increase the muscle activity of the adductor muscles, and to train the adductor muscles efficiently. Here, the hip joint angle means the angle between the base of the leg and the vertical direction, with the forward direction being a positive angle and the backward direction being a negative angle.

[0014] In the wearable training device of the present invention, the load generating section may include a guide section having a protrusion that protrudes to a side of the wearer when the wearer wears the device, and the arm section may rotate along the protrusion. In this way, the arm section is guided in the protruding direction of the protrusion as the arm section rotates, and the leg attachment section moves as the arm section moves in the protruding direction of the protrusion, so that a load can be applied to the wearer's leg in the protruding direction without the need for an external force.

[0015] In the wearable training device of the present invention employing this aspect, the protruding portion may be located rearward of the center of the guiding portion when worn by the wearer. This allows a load to be generated when the holding portion is located rearward of the center of the guiding portion, i.e., when the wearer's legs are located on the back side of the wearer, so that the adductor muscles can be trained efficiently.

[0016] In the wearable training device of the present invention, the arm portion may be made of an elastic material. In this way, even if a strong force is applied to the arm portion due to the wearer losing balance, or if the load of the load generating portion is too strong, the elasticity of the arm portion will absorb some of the force, thereby reducing the possibility of damage to the wearable training device.

[0018] Next, a wearable training device 20 will be described in detail as an example of an embodiment of the present invention. The embodiments and drawings described below are intended to illustrate a portion of the embodiment of the present invention, and are not intended to be used for the purpose of limiting the present invention to these configurations. Appropriate modifications can be made without departing from the gist of the present invention. In each drawing, corresponding components are denoted by the same or similar reference numerals.

[0019] As shown in FIG. 1, a wearable training device 20, which is an example of an embodiment of the present invention, includes a waist attachment section 22 attached to the waist of a wearer, a leg attachment section 24 attached to the leg of the wearer, an arm section 26 rotatably connecting the leg attachment section 24 to the waist attachment section 22, and a load generating section 30 that generates a load on the arm section 26. This wearable training device 20 is used by attaching the waist attachment section 22 to the waist of the wearer and the leg attachment section 24 to the leg of the wearer. When the wearer walks or steps (hereinafter referred to as "walking, etc.") while wearing the wearable training device 20, the leg attachment section 24 moves in response to the movement of the wearer's legs, and the arm section 26 rotates in response to the movement of the leg attachment section 24. At this time, a load is generated on the arm section 26 by the load generating section 30, so that a load can be applied to the wearer's legs by the wearer walking, etc., and the iliopsoas muscle, adductor muscles, etc. can be trained.

[0020] The waist attachment part 22 is a member for attaching the wearable training device 20 to the waist of the wearer. When the waist attachment part 22 is attached to the waist of the wearer, the waist attachment part 22 is positioned in a position parallel to the wearer's sacrum, so that the waist attachment part 22 is positioned at an appropriate position on the wearer and can efficiently apply a load to the iliopsoas and adductor muscles. The waist attachment part 22 may be, for example, in the form of a belt, in the form of clothing such as spats, or in the form of a fixture fixed to clothing. There are no particular limitations on the shape of the waist attachment part 22 as long as it can be attached to the waist of the wearer.

[0021] The leg attachment part 24 is a member for attaching the wearable training device 20 to the legs of the wearer, and is rotatably connected to the waist attachment part 22 and the arm part 26. The leg attachment part 24 is, for example, a belt-shaped member that can be wrapped around the leg fixed to one end of the arm part 26. It is more preferable that the leg attachment part 24 is attached to the leg of the wearer, below the thigh and above the knee. This makes it possible to efficiently apply a load to the iliopsoas muscle and adductor muscles.

[0022] The arm section 26 is a member that rotatably connects the waist attachment section 22 and the leg attachment section 24, and when the wearer wears the device, the waist attachment section 22 and the leg attachment section 24 are rotatably connected. Therefore, when the wearer's legs move due to the wearer walking, etc., the leg attachment section 24 moves with the movement of the wearer's legs, and the arm section 26 rotates with the movement of the leg attachment section 24. The arm section 26 is a band-shaped member made of an elastic material such as a flat metal or resin. By doing so, when the wearable training device 20 is worn inside clothing such as trousers, the arm section 26 is difficult to see from the outside of the clothing, etc., and it is difficult for people around to see that the wearable training device 20 is being worn. In addition, because the arm section 26 is a belt-shaped member made of an elastic material, even if a strong force is applied to the arm section 26 due to the wearer losing balance, or if the load of the load generating section 30 is too strong, part of the force is absorbed by the elasticity of the arm section 26, thereby reducing the possibility of damage to the wearable training device 20. In this case, by making the surface parallel to the wearer into a flat plate shape having a larger area than the surface approximately perpendicular to the wearer, the side toward the side of the wearer has greater rigidity than the side in the direction of travel of the wearer, and load can be efficiently applied to the adductor muscles.

[0023] 2 and 3, when the arm section 26 is worn by the wearer, a rotating body 26a that rotates with the rotation of the arm section 26 is provided on the wearer's surface at a position facing a protruding portion 40a (described later) provided on the guiding portion 40 in a state of abutting against the surface of the guiding portion 40. Therefore, when the arm section 26 rotates, the rotating body 26a smoothly guides it along the surface of the guiding portion 40, and the arm section 26 moves in the protruding direction (the direction away from the wearer when worn by the wearer) with the protruding portion 40a. In this way, a load can be applied in the direction away from the wearer, and the adductor muscles can be selectively trained.

[0024] 1, the load generating unit 30 is located on the side of the waist attachment unit 22, and is a member that applies a load to the arm unit 26 as the arm unit 26 rotates when the leg attachment unit 24 attached to the wearer's leg moves due to the wearer walking, etc. At this time, the load generating unit 30 applies a load in each of the directions of the leg's forward movement, the opposite direction to the forward movement, and the lateral direction of the leg. In this way, a load can be applied to the leg according to the wearer's walking state, etc., and the iliopsoas muscle and adductor muscle group can be trained.

[0025] 2 and 3, the load generating unit 30 includes a cam 32 connected to the arm unit 26 and rotating with the rotation of the arm unit 26, and a guide unit 40 having a protrusion 40a that protrudes laterally when the load generating unit 30 is worn by a wearer. When the wearer walks or the like and the hip joint angle changes with walking or the like, the arm unit 26 rotates with the movement of the leg attachment unit 24, and the cam 32 rotates with the rotation of the arm unit 26. The cam 32 is a plate cam having an outer peripheral surface formed of an arc having a peripheral surface whose distance from the cam rotation axis 32a varies depending on the position on the peripheral surface, and can apply a load according to the hip joint angle of the wearer to the moving direction side and the opposite side to the moving direction, and can efficiently train the iliopsoas muscle. Here, the "hip joint angle" refers to the angle of leg B (α in FIG. 4) with respect to the vertical direction A, as shown in FIG. 4. The angle of leg B is positive when it is in the direction of travel (front side), and negative when it is in the opposite direction to the direction of travel (dorsal side).

[0026] Here, the shape of the cam 32 will be described in detail. As shown in Fig. 2, the cam 32 is a plate cam having an outer circumferential surface formed of a circular arc having a circumferential surface whose distance from the cam rotation axis 32a varies depending on the position on the circumferential surface. By doing so, when the cam 32 rotates, the load increases at a position where the rate of change (mm / °) at which the distance from the center to the outer circumferential surface increases for a certain angle, and the load decreases at a position where the rate of change (mm / °) at which the distance from the center to the outer circumferential surface decreases for a certain angle change, so that when the cam 32 rotates in conjunction with the rotation of the arm portion 26, the load on the legs (load in the forward direction and in the opposite direction to the forward direction when the wearer wears it) can be adjusted according to the hip joint angle by the rotation angle of the cam 32.

[0027] As shown in FIG. 5, the load on the wearer is preferably applied when the hip joint angle of the wearer is between 0° and −30°, and more preferably between −10° and −20°. That is, when the leg is positioned behind the body, it is preferable to apply a load that is the largest in the forward direction. In this way, the iliopsoas muscle can be trained efficiently. When the hip joint angle is positive, the load is applied in the hip joint flexion direction, so that the wearer receives a negative load with respect to the walking of the wearer, that is, a force in the direction that assists the walking. FIG. 5 is a graph showing the relationship between the load and the hip joint angle, where the vertical axis shows the load (N) in the front-back direction with the hip joint flexion direction being positive, and the horizontal axis shows the hip joint angle (°).

[0028] As shown in Fig. 2 and Fig. 3, the guide unit 40 is a plate-like member having a protruding portion 40a that curves and protrudes toward the arm unit 26 at a position that is the rear side of the wearer when the guide unit 40 is worn by the wearer (a position that is the rear side of the center of the guide unit 40 when the guide unit 40 is worn by the wearer, the right side in Fig. 2 and the lower side in Fig. 3). At a position opposite to this protruding portion 40a, a rotating body 26a provided on the inner surface (the surface facing the wearer) of the arm unit 26 is located. In this way, when the wearer's leg is located on the rear side, it moves along the side of the guide unit 40 as the arm unit 26 rotates, and is guided in a direction away from the wearer along the curve of the protruding portion 40a, so that a load can be applied to the leg in the outward direction, and the adductor muscles can be efficiently trained.

[0029] It is preferable that the load on the wearer is the largest when the hip joint angle of the wearer is between -10° and -20°, that is, when the legs are positioned behind the body, as shown in Fig. 6. This makes it possible to train the adductor muscles efficiently. Note that Fig. 6 is a graph showing the relationship between the load and the hip joint angle, where the vertical axis shows the load (N) in the front-back direction with the hip joint flexion direction being positive, and the horizontal axis shows the hip joint angle (°).

[0030] According to the wearable training device 20 of the embodiment described above in detail, when the wearer wears the waist attachment part 22 on the waist and the leg attachment part 24 on the leg, and walks or the like, the arm part 26 rotates with walking or the like, and the leg attachment part 24 moves in a direction away from the wearer, thereby applying a load in the outward direction to the wearer's leg. In this way, a load is selectively applied to the adductor muscles, enabling efficient training.

[0031] In addition, when the wearer walks, etc., the arm portion 26 rotates in conjunction with the walking, etc., and the cam 32, which has an outer peripheral surface consisting of an arc with a circumferential surface whose distance from the cam rotation axis 32a varies depending on the position on the circumferential surface, rotates, thereby applying a load to the direction of travel and the opposite direction of travel depending on the hip joint angle, so that a load is selectively applied to the wearer's iliopsoas muscle, and both the iliopsoas muscle and the adductor muscles can be efficiently trained.

[0032] Furthermore, since the protrusion 40a is positioned at the rear side when worn by the wearer, when the wearer's legs are positioned at the rear side of the wearer, a load is applied to the legs in a direction away from the wearer (outward).It is known that the adductor muscles are more active when the legs are positioned at the rear when walking, so by generating a load when the legs are positioned at the rear side, the adductor muscles can be trained efficiently.

[0033] Furthermore, the load applied by the load generating unit 30 is maximum when the wearer's hip joint angle is between -10° and -20°, so that it is possible to increase muscle activity in the adductor muscles, thereby enabling the adductor muscles to be trained efficiently.

[0034] The arm 26 moves in a direction away from the wearer along the shape of the protruding portion 40a that curves as the wearer walks, etc., thereby applying a load to the wearer's legs in a direction away from the wearer (outward direction). This allows the adductor muscles to be selectively loaded and efficiently trained.

[0035] Furthermore, since the protrusion 40a is positioned on the back side of the wearer when worn by the wearer, when the wearer's legs are positioned on the rear side of the wearer, the arm portion 26 moves in a direction away from the wearer in accordance with the shape of the protrusion 40a, and an outward load can be applied when the wearer's legs are positioned on the rear side.

[0036] Furthermore, because the arm portion 26 is made of an elastic material, even if a strong force is applied to the arm portion due to the wearer losing balance, or if the load on the load generating portion is too strong, some of the force will be absorbed by the elasticity of the arm portion, thereby reducing the possibility of damage to the wearable training device 20.

[0037] It goes without saying that the present invention is not limited to the above-described embodiment, and can be embodied in various forms within the technical scope of the present invention.

[0038] For example, in the above-mentioned embodiment, the guide unit 40 is a plate-like member having a protruding portion 40a that curves and protrudes toward the arm unit 26 at a position on the rear side of the wearer, and the arm unit 26 moves along the curve of the side surface of the guide unit 40 by rotating the rotating body 26a provided on the arm unit 26, but the shape of the guide unit 40 is not limited to this as long as it has a structure that can guide the arm unit 26 in the outward direction, and for example, the curved side surface of the guide unit 40 may have a guide structure such as a groove or rail, the guide unit 40 may be provided with a rotating body and the arm unit 26 may have a guide structure, or the rotating body 26a may be a cam having an outer peripheral surface consisting of a circular arc having a peripheral surface whose distance from the cam rotation axis varies depending on the position on the peripheral surface. In any case, the same effect as the above-mentioned embodiment can be obtained. [Industrial Applicability]

[0039] As shown in the above-described embodiment, the present invention can be used as a training device in the training field, particularly for the iliopsoas and adductor muscles. [Explanation of symbols]
