Description

[Technical field]

[0001] The present invention relates to a load transmission mechanism for training equipment and a training equipment using the same. [Background technology]

[0002] Muscle strength training is considered to be good for leading a healthy daily life, not limited to sports. In muscle strength training, a method of moving the body while applying a load is widely used. There are various types of training equipment used for such training. For example, Patent Document 1 discloses a training equipment that moves the body while applying a load to the abdomen and waist.

[0003] The training device disclosed in Patent Document 1 uses two relay rollers between a tension member such as a hanging belt extending from a weight plate (load) and an input unit such as a pressure pad pressed by the user, and transmits the tension of the tension member generated by the weight plate (load) to the input unit with its direction reversed. In training using the training device disclosed in Patent Document 1, a load is applied to the reciprocating motion in one direction, which raises and lays down the upper body of the exerciser.

[0004] Strength training is said to be capable of acquiring flexible and elastic muscle strength by moving multiple muscles around the skeleton through a complex movement. Training using the training device disclosed in Patent Document 1 involves training a limited range of muscles through monotonous reciprocating movements in one direction, and there is a risk that the muscles being trained will harden and lose flexibility and elasticity. Therefore, there has been a demand for training equipment that can simultaneously perform movements in multiple directions of the muscles being trained in strength training that involve muscle loading.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] <Overview of the load transmission mechanism 1A for training equipment according to the first embodiment> 1 to 6, a load transmission mechanism 1A for a training tool according to a first embodiment of the present disclosure (hereinafter referred to as the load transmission mechanism 1A) will be described. The load transmission mechanism 1A is attached to a first training tool 100 and a second training tool 201 described below, and receives input from a user's hand.

[0012] <Description of the configuration of the load transmission mechanism 1A> The configuration and operation of a load transmission mechanism 1A of the first embodiment will be described with reference to FIGS. First, the configuration of the load transmission mechanism 1A of the first embodiment will be described with reference to Fig. 1 to Fig. 4. Fig. 1 is a front view for explaining the internal configuration of the load transmission mechanism 1A, Fig. 2 is a side view for explaining the internal configuration of the load transmission mechanism 1A, Fig. 3 is a perspective view for explaining the internal configuration of the load transmission mechanism 1A, and Fig. 4 is a view for explaining a link mechanism 30 of the load transmission mechanism 1A.

[0013] The load transmission mechanism 1A includes a housing 22. Since Fig. 1 and Fig. 3 are diagrams for explaining the internal configuration of the load transmission mechanism 1A, the housing 22 is drawn by imaginary lines in Fig. 1 and Fig. 3. The housing 22 incorporates a main driving shaft 4, an intermediate shaft 5, an orthogonal shaft 6, and a sliding shaft 13. Bidirectional force transmission between the main driving shaft 4 and the sliding shaft 13 is possible via each shaft between the main driving shaft 4 and the sliding shaft 13. The drive shaft portion 4 has an end connected to a grip portion 11, which is an input portion through which the user inputs force, and rotates together with the grip portion 11 and moves horizontally in the longitudinal direction of the housing portion 22, toward and away from the sliding shaft portion 13. The first rotation transmission portion 1K links the drive shaft portion 4 and the intermediate shaft portion 5, and is used for transmitting rotation between the drive shaft portion 4 and the intermediate shaft portion 5. The intermediate shaft portion 5 rotates in conjunction with the rotation of the main drive shaft portion 4. In addition, the intermediate shaft portion 5, the orthogonal shaft portion 6, and the sliding shaft portion 13 are connected to the main driving shaft portion 4 via a connecting and fixing portion 23 described later, and therefore move horizontally in accordance with the horizontal movement of the main driving shaft portion 4. The housing 22 constitutes the outer wall of the load transmission mechanism 1A.

[0014] The orthogonal shaft portion 6 is perpendicular to the intermediate shaft portion 5 . The second rotation transmission portion 1M links the intermediate shaft portion 5 and the orthogonal shaft portion 6, and is used for transmitting rotation between the intermediate shaft portion 5 and the orthogonal shaft portion 6. The sliding shaft portion 13 receives tension from the outside and is supported by a sliding bearing 13a, allowing reciprocating motion in the axial direction of the sliding bearing 13a. The tension 19 is generated by load applying portions 130, 230 (described later) that freely adjust the magnitude of the load on the training tool 100.

[0015] The connecting and fixing part 23 connects the driving shaft part 4, the intermediate shaft part 5, the orthogonal shaft part 6, and the sliding bearing 13a. The connecting and fixing part 23 includes a first fixed piece 23a and a second fixed piece 23b. As shown in Fig. 1, the first fixed piece 23a is a straight plate-like body, and the second fixed piece 23b is an L-shaped plate-like body.

[0016] The first fixed piece 23a is provided with a driving bearing (not shown) and an intermediate bearing 5a, the driving bearing rotatably supports the driving shaft portion 4, and the intermediate bearing 5a rotatably supports the intermediate shaft portion 5. The driving bearing and the intermediate bearing 5a support the driving shaft portion 4 and the intermediate shaft portion 5 so that the driving shaft portion 4 and the intermediate shaft portion 5 are parallel to each other. The second fixed piece 23b is an L-shaped plate whose short side and long side are perpendicular to each other. A sliding bearing 13a is provided on the short side of the L shape, and an orthogonal bearing 6a is provided on the long side of the L shape. The sliding shaft portion 13 supports the sliding bearing 13a so that it can reciprocate in the axial direction. The orthogonal bearing 6a supports the orthogonal shaft portion 6 so that it can rotate freely. A link mechanism 30 , which will be described later, is connected at both ends to the sliding shaft 13 and the orthogonal shaft 6 , and converts the rotational motion of the orthogonal shaft 6 into the reciprocating motion of the sliding shaft 13 .

[0017] The first fixed side 23a is connected to the second fixed side 23b so as to be perpendicular to the L-shaped long side of the second fixed side 23b. Therefore, the driving shaft 4, the intermediate shaft 5, and the sliding shaft 13 are provided on the connecting and fixing part 23 so as to be parallel to each other. The orthogonal shaft 6 is provided on the connecting and fixing part 23 so as to be perpendicular to the driving shaft 4, the intermediate shaft 5, and the sliding shaft 13.

[0018] The main shaft portion 4 is provided with a main shaft sprocket 4c, and the intermediate shaft portion 5 is provided with an intermediate shaft sprocket 5c. A sprocket is a gear for transmitting the rotation of a shaft to a transmission chain 10, or transmitting the rotation of the transmission chain 10 to a shaft. The transmission chain 10 is one of the machine elements used for power transmission, which transmits the rotation of a shaft as tension. The transmission chain 10, which serves as the first rotation transmission portion 1K, is suspended between the main shaft sprocket 4c and the intermediate shaft sprocket 5c to link them together, and the transmission chain 10 rotates the main shaft sprocket 4c and the intermediate shaft sprocket 5c in conjunction with each other, so that the intermediate shaft portion 5 rotates in conjunction with the rotation of the main shaft portion 4.

[0019] The second rotation transmission unit 1M includes an intermediate shaft bevel gear 5d and an orthogonal shaft bevel gear 6c. The intermediate shaft bevel gear 5d and the orthogonal shaft bevel gear 6c transmit rotation to each other by meshing their teeth with the teeth of the other. The intermediate shaft portion 5 includes the intermediate shaft bevel gear 5d, and the orthogonal shaft portion 6 includes the orthogonal shaft bevel gear 6c. A bevel gear is a gear that is attached to each of two intersecting rotation shafts, transmits rotational motion between the two shafts, and has a conical toothed surface. The intermediate shaft bevel gear 5d and the orthogonal shaft bevel gear 6c constitute the second rotation transmission section 1M, linking the intermediate shaft section 5 and the orthogonal shaft section 6 that is orthogonal to the intermediate shaft section 5, and are used to transmit rotation between the intermediate shaft section 5 and the orthogonal shaft section 6.

[0020] The first fixed piece 23a is fixed to the slider 20c of the linear guide unit 20. The linear guide unit 20 is one of the mechanical components that includes guides 20a and 20b that serve as rails (railroad tracks), a slider 20c, and a guide support base 20d, and the slider 20c that slides along the guides 20a and 20b performs linear motion smoothly with low friction. The slider 20c is attached with a connecting and fixing part 23 that connects the driving shaft part 4, the intermediate shaft part 5, the orthogonal shaft part 6, and the sliding shaft part 13, and moves the connecting and fixing part 23 along a direction parallel to the extension direction of the first rotation transmission part 1K.

[0021] The linear guide unit 20 includes a first guide 20a, a second guide 20b, a slider 20c, and a guide support base 20d. The guide support base 20d is fixed inside the housing unit 22. The first guide 20a and the second guide 20b are linear rod-shaped bodies, and are fixed to the guide support base 20d while maintaining the first guide 20a and the second guide 20b in a parallel state. The slider 20c is installed across the first guide 20a and the second guide 20b, and moves linearly on the first guide 20a and the second guide 20b.

[0022] When the grip part 11, which is the input part, is moved horizontally by the user, the connecting and fixing part 23 moves horizontally smoothly with low friction along the extension direction of the first guide 20a and the second guide 20b together with the slider 20c. The intermediate shaft part 5 and the orthogonal shaft part 6 move horizontally in association with the horizontal movement of the connecting and fixing part 23. The first guide 20a and the second guide 20b are installed in the housing part 22 so that the extension direction of the first guide 20a and the second guide 20b is parallel to the extension direction of the orthogonal shaft part 6. As a result, the direction of horizontal movement of the orthogonal shaft part 6 associated with the horizontal movement of the drive shaft part 4 is parallel to the extension direction of the orthogonal shaft part 6. In addition, two directions being parallel means that they are three-dimensionally parallel, that is, the two directions are on the same plane and do not intersect.

[0023] The upper surface 22a of the housing 22 is provided with an elongated hole 33 that penetrates vertically. The elongated hole 33 is formed so as to extend in the direction in which the slider 20c moves linearly. The sliding shaft 13 is inserted into the elongated hole 33. The sliding shaft 13 moves horizontally within the elongated hole 33 as the user moves the grip part 11 horizontally.

[0024] The link mechanism 30 has both ends connected to the sliding shaft 13 and the orthogonal shaft 6, and converts the rotational motion of the orthogonal shaft 6 into the reciprocating motion of the sliding shaft 13 in the up-down direction. The configuration of the link mechanism 30 will be described with reference to FIG. 4. The link mechanism 30 includes a first link 30a and a second link 30b. A link is generally shaped like a long, thin rod, has joints at both ends, and is a member that transmits force and motion. One end of the first link 30a is fixed to the orthogonal shaft 6, and the other end of the first link 30a is connected to one end of the second link 30b to form a first joint 30c. The first joint 30c is a joint formed by the first link 30a and the second link 30b, and is a movable part. The second link 30b can rotate approximately 360 degrees relative to the first link 30a around the first joint 30c. The other end of the second link 30b is connected to a first end 13b of the sliding shaft portion 13 to form a second joint 30d. The second joint 30d is a movable part that is a joint formed by the second link 30b and the sliding shaft portion 13. The second link 30b is rotatable approximately 360 degrees relative to the sliding shaft portion 13 around the second joint 30d.

[0025] The tension member 25 is connected to the sliding shaft 13 to transmit the tension force 19 and change the direction of extension in accordance with the axial and linear movements of the sliding shaft 13 . The tension member 25 is a flexible rope with little stretchability, and its material and thickness are determined according to the load conditions and durability requirements. Metal is mainly used as the material for the tension member 25. The tension member 25 may also be a metal chain. In the first training device 100a for both arms (see Figures 8 to 11), the tension member 25 has one end connected to the second end 13c of the sliding shaft portion 13 and the other end connected to the tension member connection portion 181 of the load application portion 130. In the first training device 100b for one arm (see Figures 12 and 13), one end of the tension member 25 is connected to the second end 13c of the sliding shaft portion 13 of one of the two load transmission mechanism units 1A, and the other end is connected to the second end 13c of the other sliding shaft portion 13. The tension member 25 extends from the load applying section 130, and is inserted through the first guide roll 26, the second guide roll 27, and the direction changing guide wheel 170 and wound around it.

[0026] The first guide roll 26 and the second guide roll 27 are each disk-shaped, and have annular grooves 26a and 27a extending in the circumferential direction formed on their outer circumferential surfaces (see Figs. 1 to 4). The tension member 25 fits into and is held in the grooves 26a and 27a. By being held in the grooves 26a and 27a, the tension member 25 is restricted from moving in the front-rear direction (left-right on the paper surface of Fig. 1).

[0027] The tension member 25 is sandwiched between a first guide roll 26 and a second guide roll 27, and its left and right movement (left and right on the plane of FIG. 2) is restricted. The first guide roll 26 and the second guide roll 27 rotate in accordance with the advancement and retreat of the tension member 25 due to friction generated between them.

[0028] The turning guide vehicle 170 converts a downward load applied to the tension member 25 by a weight 131 (described later) into an upward load. The turning guide wheel 170 has a disk shape and has an annular groove 170a extending in the circumferential direction formed on the outer circumferential surface (see Figs. 1 and 2). The tension member 25 is fitted and held in the groove 170a.

[0029] The first guide roll 26 and the second guide roll 27 are attached near the top of the guide pillar 140 via an attachment bracket 141. The load transmission mechanism 1A is allowed to pivot about the guide pillar 140. The attachment bracket 141 changes its orientation so as to follow the orientation of the load transmission mechanism 1A in accordance with the orientation of the pivoting load transmission mechanism 1A.

[0030] <Description of the Operation of the Load Transmission Mechanism 1A> The operation of the load transmission mechanism 1A will be described with reference to Figures 5 and 6. Figure 5 is a front view for explaining the internal operation of the load transmission mechanism 1A, and Figure 6 is a view for explaining the operation of the link mechanism 30 of the load transmission mechanism 1A.

[0031] First, an internal operation when the drive shaft 4 in the load transmission mechanism 1A moves horizontally will be described with reference to Figures 1 and 5. In Figure 5, the housing 22 is drawn with imaginary lines. 1 and 5, the horizontal movement of the housing 22 of the gripping part 11 in a direction away from the guide post 140 caused by the user's operation is transmitted as horizontal movement of the sliding shaft 13 via the connecting and fixing part 23. The sliding shaft 13 moves horizontally within an elongated hole 33 formed in the upper surface 22a of the housing 22. The tension member 25 connected to the second end 13c of the sliding shaft 13 extends in accordance with the horizontal movement of the second end 13c, changing the angle of the extension direction from the part of the tension member 25 held by the grooves 26a and 27a.

[0032] 4 and 6, the movement of the internal structure when the drive shaft 4 in the load transmission mechanism 1A is rotated will be described. 4 and 6, the rotational motion of the grip portion 11 by the user is transmitted by the first rotation transmission portion 1K and the second rotation transmission portion 1M as the rotational motion of the orthogonal shaft portion 6. The rotational motion of the orthogonal shaft portion 6 is further converted by the link mechanism portion 30 into the up and down motion of the sliding shaft portion 13 to move the tension member 25 forward and backward, and this, combined with the horizontal movement of the grip portion 11, generates an appropriate twisting load on the user's body parts such as the arms and shoulders for the user rotating the grip portion 11, thereby enhancing the training effect of the muscles of the entire body.

[0033] <Regarding the load transmission mechanism 1B for training equipment according to the second embodiment> A load transmission mechanism 1B for a training tool according to a second embodiment (hereinafter referred to as load transmission mechanism 1B) will be described with reference to Fig. 7. The load transmission mechanism 1B is a modified example of the load transmission mechanism 1A, and is attached to a second training tool 201 (described later) when used, and receives input from the user's feet.

[0034] Next, a load transmission mechanism 1B according to a second embodiment will be described with reference to Fig. 7 and Fig. 15. Fig. 7 is a front view for explaining the internal configuration of the load transmission mechanism 1B, and Fig. 15 is an enlarged perspective view of a footrest 271 of a second training tool 201. In Fig. 7, the housing 22 is drawn with imaginary lines. The load transmission mechanism 1A described above is a mechanical component that is mainly held by the user in the hands and used for training the upper limbs. In addition to this, a load transmission mechanism 1B is proposed for training the lower limbs. The load transmission mechanism 1B is provided with a footrest 271, and the user places his / her feet on the footrest 271 to train the lower limbs. In this way, the structure of the load transmission mechanism for training equipment of the present disclosure can be expanded for use in training the upper and lower limbs.

[0035] In the load transmission mechanism 1B, a footrest 271, which serves as an input section for the user's force, is connected to a tip 276c of a drive shaft 276. The load transmission mechanism 1B is different from the drive shaft 4 of the load transmission mechanism 1A (see FIG. 1) in the configuration of the drive shaft 276, as compared with the load transmission mechanism 1A. The drive shaft 276 has a tip 276c protruding from the same side as the sliding shaft 13, and is different from the load transmission mechanism 1A in that a footrest 271 is connected to the tip 276c. In the following description of the load transmission mechanism 1B, the components common to the load transmission mechanism 1A are given the same reference characters as those used in the description of the load transmission mechanism 1A in FIG. 7 and FIG. 15, and the description thereof is omitted, and only the components different from the load transmission mechanism 1A will be described.

[0036] The load transmission mechanism 1B is rotated 90 degrees from the load transmission mechanism 1A (see FIG. 1) and is used in an upright state with the axial direction of the orthogonal shaft 6 being approximately vertical. A drive shaft 276 is disposed near an upper portion 277 of the main body (see FIG. 15).

[0037] The user places either the left or right foot on the footrest 271. The footrest 271 has an area slightly larger than the size of the user's foot. The footrest 271 includes a third rotating shaft 273, a side plate 274a, a side plate 274b, and a connecting plate 275.

[0038] A drive shaft portion 276 is vertically connected to the center of the connecting plate 275. Flat side plates 274a, 274b are provided at both ends of the connecting plate 275 and vertically connected to the connecting plate 275. A third rotating shaft 273 to which a footrest portion 271 is attached is rotatably installed between the side plates 274a, 274b.

[0039] The third rotating shaft 273 is rotatably supported by a bearing 272 (see FIG. 15) provided on the back surface of the footrest portion 271. This allows the footrest portion 271 to rotate around the third rotating shaft 273. Furthermore, the footrest portion 271 can rotate around the main shaft portion 276.

[0040] That is, the foot rest 271 can rotate around two mutually orthogonal different axes. Therefore, by providing the structure shown in FIG. 7 and FIG. 15, the user has more freedom in placing the foot, such as the direction of the foot and the bending angle of the foot, and can place the sole of the foot on the foot rest 271 stress-free and push the foot rest 271 with the foot at a desired angle. Therefore, the user can apply a load to the flexion and extension movement of the foot placed on the foot rest 271 in a posture (angle or force) desired by the user, and can also apply a load to the twisting movement of the entire foot by changing the direction of the toes of the foot from upward to sideways during the flexion and extension movement. Therefore, in the training of the lower limbs using the second training tool 201, the flexion and extension movement with load of the foot placed on the foot rest 271 and the twisting movement with load can be performed simultaneously, so that multiple muscles of the foot can be made to perform a complex movement under a state in which an appropriately adjusted load is applied.

[0041] <Description of Operation of Load Transmission Mechanism 1B According to Second Embodiment> The user can perform various leg exercises using the load transmission mechanism 1B. The operation of the load transmission mechanism 1B will be described below with reference to Fig. 7 and Fig. 15, showing an example of leg exercise. As an example of leg exercise, the operation of the load transmission mechanism 1B accompanying the exercise of bending and straightening the user's knee joint will be described.

[0042] As the initial posture of the user, the knee joint is bent and the top of the foot is placed on the footrest 271 facing straight upward (see FIG. 16). In the state of the user's initial posture, the footrest 271 is positioned on the side closer to the user's body by bending the user's leg.

[0043] Next, the user gradually straightens the knee joint from the initial posture in a bent state (see FIG. 17), while rotating the leg by tilting the knee joint inward (see FIG. 18). When straightening the knee joint, the user pushes the leg diagonally upward to push up the footrest 271, and moves the footrest 271 upward in parallel (see FIG. 17). Then, with the knee joint in the maximum open state, the user tilts the knee joint inward as much as possible (see FIG. 18).

[0044] At this time, the state of the footrest 271 is such that the user of the load transmission mechanism 1B has their legs stretched out and is positioned on the side farthest from the user's body, and the footrest 271 has rotated to the maximum extent around the axis of the drive shaft 276 (see FIG. 18). In the load transmission mechanism 1B, the upward translation of the footrest 271 causes the sliding shaft 13 to move upward, thereby increasing the load applied by the load application unit 230.

[0045] In the load transmission mechanism 1B, by rotating the footrest 271, the rotation of the main shaft 276 is transmitted to the sliding shaft 13 via the first rotation transmission unit 1K, the second rotation transmission unit 1M, and the link mechanism 30, and the sliding shaft 13 is displaced relative to the housing 22, and the displacement displaces the weight of the load application unit 230 up and down. In the load transmission mechanism 1B, the rotation of the footrest 271 around the axis of the main shaft 276 causes the displacement of the sliding shaft 13, and thus causes a change in the load caused by the load application unit 230. The user can perform a rotational movement of the footrest 271 while resisting the biasing force generated by the load application unit 230. Note that the footrest 271 can receive the load change generated by the load application unit 230 regardless of the rotational movement at any position in the translational movement of the footrest 271.

[0046] <Overview of the first training tool 100 and the second training tool 201> The first training tool 100 will be described with reference to Fig. 8 to Fig. 13. The first training tool 100 is a device to be used for exercising the upper limbs and is equipped with a load transmission mechanism 1A that receives input from the hands. The first training tool 100 is divided into a first training tool 100a for both arms (see Fig. 8 to Fig. 11) and a first training tool 100b for one arm (see Fig. 12 and Fig. 13).

[0047] 14 to 18, a second training tool 201 will be described. The second training tool 201 is equipped with a load transmission mechanism 1A that receives input from the hands and a load transmission mechanism 1B that receives input from the feet, and is a device that supports both upper and lower limb exercises.

[0048] The load transmission mechanism 1A includes a mechanism for transmitting loads such as weights of the first training tool 100 and the second training tool 201 to the user. The load transmission mechanism 1A includes a gripping portion 11 (see FIG. 1, etc.) which is a handle that is gripped by the user, and is used for training the upper limbs such as the arms and shoulders. The load transmission mechanism 1B includes a footrest portion 271 (see FIG. 7) for the user, and is used for training the lower limbs such as the legs.

[0049] The grip portion 11 that the user grips and the user's footrest portion 271 are input portions to which the user inputs force. For example, the user holds the two gripping parts 11, which serve as input parts, in the left and right hands with the backs of both hands facing the left and right outer sides of the first training tool 100 in the initial state (see Figs. 8 and 9). Then, while holding gripping part 11 with both hands, the user inputs a pulling force to gripping part 11 by moving both arms downward at the same time. The user also holds the two gripping parts 11 with the left and right hands, with the backs of both hands facing the left and right outside of the first training tool 100 in the initial state (see Figs. 8 and 9).The user then holds gripping part 11 with both hands, and with both arms stretched out, rotates both arms outward simultaneously to the left and right to perform a chest-opening exercise, thereby inputting a force via gripping parts 11 to rotate load transmission mechanism 1A outward. The grip portion 11 is annular, and the user grips the grip portion 11 by putting his / her hand through the grip portion 11 .

[0050] The user sits on the right side (front in the figures) of seat 211 of second training machine 201 (see FIGS. 14 to 18) in the initial state. The user then raises his right arm and grasps grip portion 11 with his right hand. The user then swings his right arm down forward while maintaining the state in which he is grasping grip portion 11 with his right hand, thereby inputting a pulling force to grip portion 11, which serves as an input portion. The user sits on the right side (near the front in the figures) of the seat 211 of the second training machine 201 (see Figs. 14 to 18), places the left leg on the footrest 271 that serves as the input section of the load transmission mechanism 1B, and bends the knee (see Fig. 16).The user then extends the left leg, thereby inputting a pushing force to the footrest 271 (see Fig. 17).

[0051] <First training tool 100> The configuration of the first training tool 100 is shown in Figures 8 to 13. The first training tool 100 is a training tool to which a load transmission mechanism 1A is attached when used. The first training tool 100 shown in Figs. 8 to 13 is divided into a first training tool 100a for both arms (see Figs. 8 to 11) and a first training tool 100b for one arm (see Figs. 12 and 13).

[0052] The first training device 100a for both arms shown in Figures 8 to 11 is a device in which the handles (grip parts 11) of the two load transmission mechanism parts 1A on the left and right are held with both hands and the upper limbs are exercised while always maintaining the same height, thereby coordinating the functions of the upper limbs and enhancing the functional correlation. The first training device 100b for one arm shown in Figures 12 and 13 is similar to the first training device 100a for both arms in that the handles (grip parts 11) of the two load transmission mechanisms 1A, one on the left and one on the right, can be held with both hands. However, the first training device 100b for one arm is mainly a device for holding one of the grip parts 11 of the two load transmission mechanisms 1A, one on the left and one on the right, in one hand and exercising with each upper limb. The first training tool 100 includes a first training tool 100a for both arms (see Figs. 8 to 11) and a first training tool 100b for one arm (see Figs. 12 to 13), and common components are designated by the same reference numerals.

[0053] <Description of the Configuration of the First Training Tool 100> The first training tool 100 can be used for training the upper limbs of a user by attaching the load transmission mechanism 1A to the first training tool 100. The configuration of the first training tool 100 will be described using an example in which the load transmission mechanism 1A is attached to the first training tool 100.

[0054] 8 to 13, the first training tool 100 includes a seating section 110, a framework 120 supporting the seating section 110, a load applying section 130 provided on the framework 120 and capable of adjusting the magnitude of the load, and two guide posts 140 fixed vertically at a predetermined interval to the framework 120 so that the seating section 110 is located at the center of the frame 120. The first training tool 100 further includes two load transmission mechanisms 1A each having one end thereof fitted thereto so as to be movable up and down and rotatable horizontally, a gripping section 11 connected to the lower end of the driving shaft 4 of each of the two load transmission mechanisms 1A, and a tension member 25 having one end connected to the load applying section 130 and the other end wound around a direction changing guide wheel 170 provided on the framework 120 and connected to the other end side of the fitting position of the guide posts 140 of the load transmission mechanism 1A. In the load transmission mechanism 1A, a load from the load applying unit 130 is applied via the tension member 25 to the gripping unit 11 in response to the rotation of the shaft.

[0055] The seating section 110 comprises a seat 111 suitable for a user of the first training apparatus 100 to sit on while facing forward, and a seat support 112 provided vertically on the underside of the seat 111.

[0056] The framework 120 stably places the first training apparatus 100 on the floor surface and serves as the skeleton of the entire first training apparatus 100, to which the seating section 110, the load applying section 130, and the two guide pillars 140 are fixed. A seat pillar 112 is inserted into a hole provided vertically forward from the center of the underside of the framework 120, and the seating section 110 is supported by the framework 120. The framework 120 is provided with a thigh holding section 121 that prevents the thighs of a user seated on the seat 111 from lifting up. The thigh holding section 121 is preferably provided so that the user can create an appropriate arch in their back during training.

[0057] The load applying unit 130 is provided on the frame 120, and is capable of freely adjusting the magnitude of the load on the first training apparatus 100. The load applying unit 130 is equipped with a weight 131 such as a stack weight made of a plurality of plate-like plates that are metal weight members, a weight guide pillar 132 that supports the weight 131 on the frame 120 so as to be movable up and down, and a clamp (not shown) that can adjust the number of weights 131 stacked on top of each other so as to be freely connected and separated from each other. The load (load) of the load applying unit 130 is adjusted by adjusting the number of weights 131. The pair of cylindrical weight guide pillars 132 are fixed vertically at the upper and lower ends to the frame 120 at a predetermined left-right interval behind the seating unit 110, and the plate-like plates of the weight 131 are inserted through the through-holes and stacked, and are supported on the frame 120 so as to be movable up and down.

[0058] A connection part 7 is provided on the housing part 22 in order to connect the load transmission mechanism part 1A to the first training tool 100. The connection part 7 of the load transmission mechanism part 1A is in the form of a cylindrical connection tube part 8. A guide post 140 is inserted into the connection tube part 8. The connection tube part 8 is made of a material with low sliding resistance, such as fluororesin. As a result, the load transmission mechanism part 1A can smoothly move up and down and rotate in the first training tool 100.

[0059] The load transmission mechanism 1A is fitted to the guide support 140 by inserting the guide support 140 into the connection portion 7, and is moved so as to be vertically movable and horizontally rotatable. The gripping parts 11 connected to the drive shaft parts 4 of the two load transmission mechanisms 1A are annular handles that serve as input parts for inputting force by being held by the user's hands. Each gripping part 11 is rotated horizontally around the drive shaft part 4 of the load transmission mechanism 1A. In the initial state of the first training tool 100 (see Figs. 8 and 9), the back of the hand of the user holding each gripping part 11 faces the left and right outside of the first training tool 100, and each gripping part 11 is located higher than the position of the hand of the user who is seated on the seat 111 and stretches his / her arm upward. The user can then grasp the gripping part 11 with his / her hand and lower his / her arm to lower the load transmission mechanism 1A through the gripping part 11. At this time, the user moves both arms outward from the midline (the center line between the left and right sides of the body) to open the chest. Figures 10 and 11 show the state of the first training tool 100a for both arms when the user is in a position with the chest open.

[0060] Of the first training device 100, Figures 8 to 11 show a first training device 100a for both arms that is used by moving both arms simultaneously, and Figures 12 and 13 show a first training device 100b for one arm that is used by moving each arm separately. In the first training device 100a for both arms, two ropes or wires of the same length are used as the pulling members 25, one end of each of the two pulling members 25 is connected to a weight 131, and the other end of each is connected to the load transmission mechanism 1A. The two pulling members 25 are each wound around a direction changing guide wheel 170. The direction changing guide wheel 170 converts the downward load applied to the pulling members 25 by the weight 131 into an upward load. The two tension members 25 and the weight 131 are connected at two tension member connection portions 181 (see FIGS. 9, 11, etc.).

[0061] A single rope or wire is used as the pulling member 25 of the first training device 100b for one arm shown in Figures 12 and 13. Both ends of this single pulling member 25 are connected to two load transmission mechanisms 1A, respectively. A movable pulley 134 is housed in a box section 133 provided at the upper end of the weight 131, and the pulling member 25 is wound around this movable pulley 134. The pulling member 25 is drawn into the box section 133 through two holes 136 provided on the upper surface of the box section 133 (only one hole 136 is shown in Figure 12). When one of the two load transmission mechanisms 1A is pulled down, the pulling member 25 lifts the weight 131 upward together with the movable pulley 134, using the other load transmission mechanism 1A as a fulcrum. The movable pulley 134 is rotatably supported by a support base 135 fixed inside the box portion 133 .

[0062] 8 and 9, a load is applied by the tension of the tensioning member 25 against the horizontal rotation of the load transmission mechanism 1A outward around the guide post 140. The tension of the tensioning member 25 is generated by the load applying unit 130 that freely adjusts the magnitude of the load of the first training tool 100. Note that in the second training tool 201 described later, similarly to the first training tool 100, the tension of the tensioning member 280 is generated by the load applying unit 230 that freely adjusts the magnitude of the load of the second training tool 201.

[0063] 10 and 11, a load acts to close the load transmission mechanism 1A inward so that it faces the front, and the user can rotate the load transmission mechanism 1A to a predetermined angle to face the load. The load acting to close the load transmission mechanism 1A inward so that it faces the front is proportional to the load of the load application unit 130 and is roughly inversely proportional to the vertical position of the load transmission mechanism 1A.

[0064] In addition, in the first training device 100b for one arm shown in Figures 12 and 13, by adjusting the load application unit 130, it is possible to train by varying the load associated with the lifting and lowering operation of the load transmission mechanism unit 1A for each user.

[0065] <Explanation of how to use the first training tool 100> A typical method of using the first training tool 100 will be described in order. First, weight 131 is set according to the load taking into consideration the user's muscle strength, purpose, etc. The user sits on seat 111 facing forward, and seat 111 is adjusted to an appropriate height and fixed so that the soles of the feet touch the floor. Furthermore, thigh presser 121 is adjusted to an appropriate height and fixed so that it comes into contact with the upper surfaces of the thighs of the user seated on seat 111.

[0066] Next, the user stands up, adjusts the load transmission mechanism 1A to its initial state (see Figs. 8 and 9) facing forward, and grasps the grips 11 with the backs of their hands facing the left and right outside of the first training tool 100. Then, while grasping the grips 11 with the hands extended upward, and pulling the grips 11 downward, the user sits down on the seat 111 facing forward.

[0067] Next, the user twists both upper arms outward against the rotational biasing force acting on the gripping parts 11 by a force proportional to the load of the load applying part 130, and rotates each gripping part 11 horizontally relative to the load transmission mechanism part 1A, so that the backs of the hands gripping each gripping part 11 face outward from the front direction of the first training tool 100. By taking this "dodge motion" position, both the flexor and extensor muscles are "relaxed," and the shoulders and arms are in a relaxed state. In addition, the gripping parts 11 are biased upward by the load of the load applying part 130, and the muscles around the shoulder girdle and the like are appropriately "stretched."

[0068] Next, the user bends both arms against the load of the load application unit 130 to "shorten" the muscles and pull down the grip unit 11 so that the muscles around the shoulder girdle, etc., which have been moderately "stretched", induce a "reflex". At this time, the user pulls down the grip unit 11 with both hands while adding the "relaxation" and "stretching" movements of twisting the upper arms outward. This movement of twisting the upper arms outward rotates each grip unit 11 further outward horizontally relative to the load transmission mechanism unit 1A, thereby pulling up the weight 131 and reducing the load in the initial movement of pulling down both arms. In this way, when bending both arms to pull down the grip unit 11 to "shorten" the muscles, by further twisting the upper arms outward to create the appropriate timing of "shortening" while adding the "relaxation" and "stretching" movements, each muscle group can obtain the timing of "relaxation-stretch-shortening" and perform the movement with good interlocking.

[0069] Furthermore, the user can apply an appropriately adjusted load by the load applying unit 130 in three directions, downward, rotational, and lateral, by pulling down both arms and twisting them outward while stretching them outward, so that each muscle group that has been appropriately "stretched" can obtain the timing of "relaxation-stretch-contraction" and perform movements with good interlocking. Note that when the upper arms are stretched outward, there is no large fluctuation in the load applied by the load applying unit 130 (weight 131) in response to the horizontal movement of the grip unit 11 (drive shaft 4).

[0070] When the user bends both arms to pull down the grip 11, the user gradually spreads both arms outward so that each load transmission mechanism 1A faces outward against the force that rotates the load transmission mechanism 1A so that it faces forward. The force that rotates the load transmission mechanism 1A so that it faces forward is approximately inversely proportional to the position (height) of the load transmission mechanism 1A, so that the resistance to spreading the arms outward decreases as the user bends both arms to pull down the grip 11. Therefore, when the user bends both arms to pull down the grip 11, the user can smoothly perform the action of gradually spreading the arms outward while pulling down the grip 11 by outputting approximately constant muscle force to spread the arms outward, and it becomes possible to prevent co-contraction of the agonist and antagonist muscles.

[0071] Agonist muscles are muscles that generate the main force required for movement. Antagonist muscles are muscles that act in the opposite direction to agonist muscles, providing a certain degree of resistance or counter-movement to a specific movement. Antagonist muscles act in the opposite direction to agonist muscles and control the action of agonist muscles. For example, when bending the elbow, the biceps corresponds to the agonist muscle, and the triceps on the opposite side (back side) of the biceps corresponds to the antagonist muscle. On the other hand, when straightening the elbow, the triceps corresponds to the agonist muscle, and the biceps corresponds to the antagonist muscle. When muscles are relaxed, they are relaxed and elongated, and they exert force by shortening (contracting). For example, bending the elbow is achieved by shortening the biceps and lengthening the triceps, which is the antagonist muscle. However, if both the biceps and triceps are tense and attempt to shorten, the elbow cannot be bent. Co-contraction means that both the agonist and antagonist muscles try to shorten at the same time, and it hinders the intended movement. Co-contraction is likely to occur when the body is tense due to excessive force being applied and unable to relax. In sports, co-contraction is an obstacle to the series of supple movements that build up momentum and then release the force, such as in pitching, throwing, and hitting.

[0072] Next, the user lowers each grip 11 to approximately shoulder height, and then twists the upper arms inward and closes both arms inward while following the biasing forces of the load applying units 130, slowly returning the backs of the hands to a seated position following the grips 11. This completes one cycle of training. This training is then repeated an appropriate number of times.

[0073] <Second training equipment 201> The configuration and operation of the second training tool 201 will be described with reference to Fig. 14 to Fig. 18. Fig. 14 is a perspective view of the second training tool 201, and Fig. 15 is an enlarged perspective view of a footrest section 271 of the second training tool 201. Figs. 16 to 18 are side views showing first to third modes of the second training tool 201 in use. <Description of the configuration of the second training tool 201> 14, the second training tool 201 includes a seating section 210 on which a user sits, a load applying section 230 that applies a load, and a cylindrical guide pole 240 that extends in the vertical direction. The second training tool 201 further includes a lifting section 250 that is guided by the guide pole 240 and is connected to the lifting section 250 so as to be movable in the vertical direction and rotatable, and a gripping section 260 provided on the lifting section 250. The second training tool 201 further includes a footrest 271 on which the sole of the user's foot is placed, slide rails 222a, 222b, a load transmission mechanism 1B that includes the footrest 271, and a tension member 280 that has one end connected to the lifting section 250 and the other end connected to the load transmission mechanism 1B and applies the load from the load applying section 230 to the lifting section 250 and the load transmission mechanism 1B.

[0074] The load transmission mechanism 1A can be applied and used as the lifting section 250. The gripping section 260 corresponds to the gripping section 11 of the load transmission mechanism 1A, and is an input section to which the user inputs a force.

[0075] First, the structure of the second training machine 201 will be described with reference to FIGS. 14, the seating section 210 of the second training apparatus 201 is supported by a framework 220 which serves as a base frame of the second training apparatus 201. The framework 220 serves as the skeleton of the entire second training apparatus 201 and serves to stably install the second training apparatus 201 on the floor surface. The framework 220 can be formed by processing a rectangular column pipe material or a plate material made of a material having a certain level of rigidity or more, such as steel, aluminum, stainless steel, or resin, and fixing the material with bolts, welding, or the like.

[0076] The seating section 210 is composed of a seat 211 on which a user sits, and a seat pillar 212 that supports the seat 211. The seat pillar 212 is fixed to the framework 220. The seat pillar 212 holds the seat 211. Although not shown, the seat pillar 212 has a through hole for passing the tension member 280 in the front-rear direction. The seat 211 is a place where a user of the second training apparatus 201 sits, and as shown in FIG. 14, the seat 211 is a rectangle that is long in the left-right direction of the second training apparatus 201. This is to allow the user to sit on either the right or left side of the seat 211, but it does not have to be rectangular as long as the user can sit comfortably, and may be square or circular.

[0077] As shown in FIG. 14, the seating portion 210 may include a backrest 215 between the load applying portion 230 and the rear of the seat 211 for supporting the user's body during use. A guide pillar 240 extending in the vertical direction is provided on the framework 220. As shown in Fig. 14, the guide pillar 240 is provided in a position forward of the load applying section 230 and rearward of the seating section 210. As shown in Fig. 14, the framework 220 includes an upper housing 225 for guiding the tension member 280 in the vertical direction, behind the guide pillar 240. The guide pillar 240 has a lower end connected to the framework 220 and an upper end connected to and fixed to the upper housing 225.

[0078] 14, a shock absorbing material 241 may be provided on guide pillar 240. Shock absorbing material 241 is a member for absorbing a shock when lifting section 250 comes into contact with upper housing 225 and framework 220. Shock absorbing material 241 may be realized by, for example, rubber, sponge, or the like.

[0079] The lifting / lowering unit 250 shown in FIG. 14 is attached to the guide column 240. As shown in FIG. 14, the lifting / lowering unit 250 is attached to the guide column 240 so as to be movable up and down. Although not shown, the lifting / lowering unit 250 has a through hole for inserting the guide column 240. Therefore, the lifting / lowering unit 250 moves up and down along the guide column 240. In addition, the lifting / lowering unit 250 is attached to the guide column 240 so as to be rotatable with respect to the guide column 240 as the central axis. Therefore, a certain level of rigidity is required for the guide column 240. Therefore, the guide column 240 may be made of stainless steel, for example. In the second training tool 201, the load transmission mechanism 1A according to the first embodiment described above may be applied as the lifting / lowering unit 250.

[0080] 14, the load transmission mechanism 1B of the second training machine 201 slides along slide rails 222a and 222b. The slide rails 222a and 222b are suspended from a frame 220 of the second training machine 201 and a frame 221 disposed in front of the frame 220, and are fixed at both ends.

[0081] As shown in FIG. 14, the load applying section 230 is composed of a pair of cylindrical weight guide posts 232 whose upper and lower ends are fixed to the frame 220, and a weight 233 that is provided so as to be movable up and down relative to the weight guide posts 232. The weight 233 is provided with a through hole for inserting the weight guide posts 232. The load applying section 230 is configured to be able to adjust the magnitude of the load to be applied, and specifically, the weight 233 such as a stack weight that serves as a weight member is made into a plate-like member, and the load can be adjusted by the number of sheets. Therefore, the load applying section 230 may be provided with a clamp (not shown) that adjusts the number of sheets to be stacked so that the multiple weights 233 can be connected and separated from each other. In addition, the weight guide posts 232 are provided with an impact absorbing material 231 that suppresses the weight 233 from colliding with the frame 220 with an impact of a certain level or more.

[0082] <How to use the second training device 201> A method of using the second training tool 201 will now be described with reference to FIGS. As shown in Fig. 16, the user sits on the right side of the second training apparatus 201, that is, on the right side of the seat 211 (the left front side of the paper in Fig. 16). That is, the user sits on the seat 211 with the load transmission mechanism 1B on the left side and the backrest 215 on the right side. Then, as shown in Fig. 16, the user places the left leg on the footrest 271 of the load transmission mechanism 1B with the knee bent.

[0083] From this state, the user extends the left leg and pushes the load transmission mechanism 1B. Then, as shown in Fig. 16, the load transmission mechanism 1B slides along the slide rails 222a, 222b. At this time, a load that pulls the second training apparatus 201 rearward (to the left on the paper in Figs. 16 to 18) is applied to the load transmission mechanism 1B by the tension member 280 connected to the connection part 279.

[0084] Then, from the state in which the legs are stretched as shown in Fig. 16, the load transmission mechanism 1B is slowly slid back to the original position along the slide rails 222a, 222b. This exercise is repeated a certain number of times. In other words, the user repeats the posture between Fig. 16 and Fig. 17 a predetermined number of times.

[0085] As shown in Fig. 18, the user may push the load transmission mechanism 1B farther by twisting the waist further than in the state shown in Fig. 17, and in that case, the user may train the waist while stretching the legs. This posture is possible because the footrest 271 is configured to be freely rotatable about the axis of the drive shaft 276 relative to the load transmission mechanism 1B body. The user may perform leg extension and contraction exercises between Fig. 16 and Fig. 17, or may perform leg extension and contraction exercises with waist twisting between Fig. 16 and Fig. 18.

[0086] 16 to 18, on the left side of the second training apparatus 201 (the rear side of the paper in FIGS. 16 to 18). In other words, the user can exercise with the right leg by sitting on the seat 211 with the load transmission mechanism 1B on the right side of the user and the backrest 215 on the left side.

[0087] Therefore, the user can use the second training machine 201 to perform bidirectional rotational exercises around the waist while strengthening both legs. Specifically, the user spreads his / her legs and pushes off the load transmission mechanism 1B in a kicking motion. This is a good example for strengthening the muscles around the hip joints, around the pelvis, thighs, knees, etc.

[0088] Each muscle group in the leg can achieve the timing of "relaxation-stretch-contraction" and perform movements in good coordination. Specifically, in the state shown in Fig. 16, no load is applied to the left foot by the load application unit 230, and the muscles are in a "stretched" state. In addition, the state shown in Fig. 16 is also a state in which the foot is simply placed on the footrest 271, and the overall state is relaxed, so it can also be said to be a "relaxed" state.

[0089] From this point, the user applies force to the foot and pushes the load transmission mechanism 1B to which the load is applied by the load application unit 230. That is, in the process shown in FIG. 16 to FIG. 17 or FIG. 18, the load of the load application unit 230 is applied to the left leg of the user, and the "contracted" state can be generated in the muscles of the left leg of the user. Then, in the state shown in FIG. 17 or FIG. 18, by rotating the foot rest 271 relative to the load transmission mechanism 1B, the internal crank mechanism pulls the connection part 279 into the load transmission mechanism 1B, thereby reducing the load applied by the load application unit 230 on the foot. That is, in the state in which the load transmission mechanism 1B is rotated as shown in FIG. 17 or FIG. 18, the "contracted" state can be generated in the foot of the user. Also, since the load applied by the load application unit 230 is not applied significantly to the parallel movement of the foot rest 271, the load transmission mechanism 1B can focus on the load associated with the rotation of the foot rest 271.

[0090] In the process of transitioning from the state shown in FIG. 17 or FIG. 18 to the state shown in FIG. 16, the leg is returned to the state shown in FIG. 16, thereby producing a "stretched" state of the muscle. Therefore, by repeating a cycle of movement in which the load transmission mechanism 1B is moved from the state shown in Fig. 16 to the state shown in Fig. 17 or Fig. 18 and then returned to the state shown in Fig. 16, a timing of "relaxation-extension-contraction" is generated, and movement can be performed with good interlocking. As for leg movement, the state shown in Fig. 16 may be set as the initial state, or one cycle of movement may be performed with the state shown in Fig. 17 or Fig. 18 as the initial state. However, since it is desirable to start the movement from a "relaxed" state, when starting the movement with the state shown in Fig. 17 or Fig. 18 as the initial state, it is desirable to start the movement from an unloaded state in the initial state with the cooperation of another person, etc.

[0091] Since the second training machine 201 is structured to train one leg at a time instead of both legs, there is no need to prepare a load transmission mechanism 1B for training both legs at once, and therefore the size can be made more compact than if it were configured to accommodate both legs. Furthermore, the second training machine 201 can be made narrower than if two load transmission mechanisms 1B were provided for both legs, so the area of ​​the space to be prepared as an installation space can be made smaller. In the exercises shown in Figs. 16 and 17, the user may perform the exercise by sitting on the seat 210 with the load transmission mechanism 1B facing forward and with the backrest 215 facing away from the second training machine 201.

[0092] <Summary of the first training tool 100 and the second training tool 201> The first training tool 100 and the second training tool 201 described above are tools that appropriately train the muscles of the shoulders, arms, back, legs, etc., by initial load training (registered trademark). Here, initial load training is defined as "training that utilizes a change in the body to a position where a reflex occurs and the accompanying change in the center of gravity position, etc., to promote a series of motion processes of "relaxation-stretch-shortening" of the agonist muscle, while preventing the co-contraction of the antagonist muscle and muscles that act antagonistically." A reflex is a reaction that occurs unconsciously. Initial load training is training that is completely different from final load training, which applies a load to the end and enlarges the muscle while keeping the muscle in a state of tension (hardening). In initial load training, it is necessary to carry out training while grasping the overall image of the movement, such as the point where the load is applied, the point and angle where the load is released, the rhythm, and the continuity of the muscle output. Conventional load training has the problem that it is difficult to take an appropriate movement or form due to the balance of the body and partial hardening. However, the first training tool 100 and the second training tool 201 that realize the initial load training easily induce training with an ideal series of movements and form.

[0093] In the initial load training using the first training tool 100 and the second training tool 201, first, "inter-segmental force transmission from the center (body trunk) to the extremities" is performed, that is, the human muscle, which has the characteristic of contracting without stretching itself, is relaxed and put into a relaxed state. Then, in the initial load training, an appropriate load is applied to the muscle spindle-tendon organ, which is a sensory receptor, and a muscle stretch reflex is generated, inducing the exertion of force when the muscle shortens from a moderately stretched point or from a passively stretched point, and the load is gradually decreased instantaneously and continuously, thereby obtaining an active state without co-contraction, which makes it possible to promote and develop neuromuscular control. The muscle stretch reflex is a spinal reflex, and refers to the phenomenon in which a skeletal muscle contracts when it is passively stretched. This contraction occurs when the muscle spindles in the muscle sense the tension caused by the muscle stretch. The muscle stretch reflex also has a defensive function, in that the muscle contracts to avoid injury when it is overstretched. An example of a muscle stretch reflex is the patellar tendon reflex. Cardiac muscle is said to be the only muscle in the human body that does not contract in unison, and initial load training is a type of training that prevents contraction by promoting the series of "relaxation-stretch-shortening" movements in muscles other than the cardiac muscle.

[0094] The initial load training using the first training tool 100 and the second training tool 201 is a training that uses the load of the training tool to cause a reflex in the muscles, so that the muscles that should be working work well, and improve the function of the muscles and nerves. The load is used as a catalyst to promote well-timed contraction and shortening of relaxed muscles. This type of training promotes a series of "relaxation-stretch-shortening" movements, and prevents co-contraction, thereby improving the function and coordination of the nerves and muscles, reducing the burden on the body such as muscle pain and fatigue, and obtaining flexible and elastic muscles without muscle hardening. In addition, by promoting aerobic metabolism with little forced increase in heart rate and blood pressure, it is effective in preventing lifestyle-related diseases such as diabetes and high blood pressure, and promoting the healing of ligament damage and fractures, and can create a beneficial state for the body, such as releasing stress on the nerves, muscles, and joints and removing waste products.

[0095] <Configuration of the load transmission mechanism 1C for training equipment according to the third embodiment> A load transmission mechanism 1C for a training tool according to a third embodiment (hereinafter referred to as the load transmission mechanism 1C) will be described with reference to Fig. 19. Fig. 19 is a front view for explaining the internal configuration of the load transmission mechanism 1C according to the third embodiment. The load transmission mechanism 1C is a modified example of the load transmission mechanism 1A, is attached to the first training tool 100 when used, and receives input from the user's hand. In the following explanation of the load transmission mechanism 1C, only differences from the load transmission mechanism 1A will be explained, and points in common with the load transmission mechanism 1A will be denoted by the same reference numerals as the load transmission mechanism 1A in Fig. 19, and explanations thereof will be omitted.

[0096] The load transmission mechanism 1C has a configuration in which a feed roll 28 is further added to the configuration of the load transmission mechanism 1A. The first guide roll 26 , the second guide roll 27 , and the feed roll 28 are mounted near the top of the guide post 140 via mounting brackets 141 . The tension member 25 extends from the load applying section 130, and is inserted through the first guide roll 26, the second guide roll 27, the feed roll 28, and the direction changing guide wheel 170 and wound around it. The tension member 25 is connected to the sliding shaft 13 to transmit the tension 19, and extends in the tangential direction of the outer circumferential surface of the cylindrical feed roll 28, changing the extension direction in accordance with the axial and linear movements of the sliding shaft 13. The tension member 25 connected to the second end 13c of the sliding shaft 13 extends in accordance with the horizontal movement of the second end 13c, changing the angle of the extension direction from the feed roll 28.

[0097] The feed roll 28 has a disk shape and has an annular groove 28a extending in the circumferential direction formed on the outer circumferential surface (see FIG. 19). The tension member 25 is fitted and held in the groove 28a. The feed roll 28 is disposed between the first guide roll 26, the second guide roll 27 and the sliding shaft portion 13, and regulates the movement of the tension member 25 in the front-rear direction (left-right direction on the paper surface of FIG. 19). The feed roll 28 rotates in accordance with the advancement and retreat of the tension member 25 due to friction generated between the feed roll 28 and the tension member 25 .

[0098] <Configuration of the Load Transmission Mechanism 1D for Training Apparatus of the Fourth Embodiment> A load transmission mechanism 1D for training equipment according to a fourth embodiment (hereinafter referred to as load transmission mechanism 1D) will be described with reference to Fig. 20. Fig. 20 is a front view for explaining the internal configuration of the load transmission mechanism 1D according to the fourth embodiment. The load transmission mechanism 1D is a modified version of the load transmission mechanism 1B and also a modified version of the load transmission mechanism 1C, which is attached to a second training equipment 201 and receives input from the user's foot. In the following explanation of the load transmission mechanism 1D, only the differences from the load transmission mechanism 1B will be explained, and the points in common with the load transmission mechanism 1B will be denoted by the same reference numerals as the load transmission mechanism 1B in Fig. 20 and will not be explained again.

[0099] The load transmission mechanism 1D has a configuration in which a feed roll 28 is further added to the configuration of the load transmission mechanism 1B. Furthermore, compared to the load transmission mechanism 1C, the load transmission mechanism 1D differs in the configuration of the drive shaft 276 from the drive shaft 4 (see FIG. 19) of the load transmission mechanism 1C. The drive shaft 276 differs from the load transmission mechanism 1A in that a tip 276c protrudes from the same side as the sliding shaft 13 and a footrest 271 is connected to the tip 276c.

[0100] The first guide roll 26 , the second guide roll 27 , and the feed roll 28 are attached near the tip of the guide post 140 via a mounting bracket 141 . 7, 1D shown in Fig. 20, and 1F shown in Fig. 22 are provided with a footrest 271 and mounted on a second training apparatus 201. In this case, the first guide roll 26, the second guide roll 27, and the feed roll 28 are installed near the bottom of the seat 211 via a mounting bracket 141. The tension member 25 extends from the load applying portion 230, and is inserted through the first guide roll 26, the second guide roll 27, the feed roll 28, and the pulley 285h and wound around it. Similar to the load transmission mechanism 1C, the tension member 25 is connected to the sliding shaft 13 to transmit the tension 19, and extends in the tangential direction of the outer circumferential surface of the cylindrical feed roll 28, changing the extension direction in accordance with the axial and linear movements of the sliding shaft 13. The tension member 25 connected to the second end 13c of the sliding shaft 13 extends in accordance with the horizontal movement of the second end 13c, changing the angle of the extension direction from the feed roll 28.

[0101] The feed roll 28, like the load transmission mechanism 1C, is disk-shaped and has an annular groove 28a extending in the circumferential direction formed on its outer circumferential surface (see FIG. 20). The tension member 25 is fitted and held in the groove 28a. The feed roll 28 is disposed between the first guide roll 26, the second guide roll 27 and the sliding shaft portion 13, and regulates the movement of the tension member 25 in the front-rear direction (the up-down direction on the paper surface of FIG. 20). The feed roll 28 rotates in accordance with the advancement and retreat of the tension member 25 due to friction generated between the feed roll 28 and the tension member 25, similarly to the load transmission mechanism 1C.

[0102] <Configuration of the Load Transmission Mechanism 1E for Training Apparatus of the Fifth Embodiment> A load transmission mechanism 1E for training equipment according to a fifth embodiment (hereinafter referred to as the load transmission mechanism 1E) will be described with reference to Fig. 21. Fig. 21 is a front view for explaining the internal configuration of the load transmission mechanism 1E according to the fifth embodiment. The load transmission mechanism 1E is a modified example of the load transmission mechanism 1A, is attached to the first training equipment 100 when used, and receives input from the user's hand. In the following explanation of the load transmission mechanism 1E, only differences from the load transmission mechanism 1A will be explained, and points in common with the load transmission mechanism 1A will be denoted by the same reference numerals as the load transmission mechanism 1A in Fig. 21 and explanations thereof will be omitted.

[0103] The load transmission mechanism 1E has a configuration in which the first guide roll 26, the second guide roll 27, and the mounting bracket 141 are removed from the configuration of the load transmission mechanism 1A. The tension member 25 extends from the load applying portion 230 , is inserted through the direction changing guide wheel 170 , is wound around the direction changing guide wheel 170 , and is connected to the sliding shaft portion 13 . The tension member 25 is connected to the sliding shaft 13 to transmit the tension 19, and changes its extension direction in accordance with the axial and linear movements of the sliding shaft 13. The tension member 25 connected to the second end 13c of the sliding shaft 13 extends in accordance with the horizontal movement of the second end 13c, and changes the angle of the extension direction from the direction changing guide wheel 170.

[0104] <Configuration of the load transmission mechanism 1F for training equipment according to the sixth embodiment> A sixth embodiment of a load transmission mechanism 1F for training equipment (hereinafter referred to as load transmission mechanism 1F) will be described with reference to Fig. 22. Fig. 22 is a front view for explaining the internal configuration of the load transmission mechanism 1F according to the sixth embodiment. The load transmission mechanism 1F is a modified version of the load transmission mechanism 1B and also a modified version of the load transmission mechanism 1E, which is attached to a second training equipment 201 and receives input from the user's foot. In the following description of the load transmission mechanism 1F, only differences from the load transmission mechanism 1B will be described, and commonalities with the load transmission mechanism 1B will be denoted by the same reference numerals as the load transmission mechanism 1B in Fig. 22 and will not be described.

[0105] The load transmission mechanism 1F has a configuration in which the first guide roll 26, the second guide roll 27, and the mounting bracket 141 are removed from the configuration of the load transmission mechanism 1B. The load transmission mechanism 1F is also different from the load transmission mechanism 1E in the configuration of the drive shaft 276, which is different from the drive shaft 4 (see FIG. 21) of the load transmission mechanism 1E. The drive shaft 276 differs from the load transmission mechanism 1A in that a tip 276c protrudes from the same side as the sliding shaft 13, and a footrest 271 is connected to the tip 276c. The tension member 25 extends from the load applying portion 230, is inserted through the pulley 285h, is wound around it, and is connected to the sliding shaft portion 13. The tension member 25 is connected to the sliding shaft 13 to transmit the tension 19, and changes its extension direction in accordance with the axial and linear movements of the sliding shaft 13. The tension member 25 connected to the second end 13c of the sliding shaft 13 extends in accordance with the horizontal movement of the second end 13c, and changes the angle of the extension direction from the pulley 285h.

[0106] <Configuration of the Load Transmission Mechanism 1G for Training Apparatus of the Seventh Embodiment> A seventh embodiment of a load transmission mechanism 1G for training equipment (hereinafter referred to as load transmission mechanism 1G) will be described with reference to Fig. 23 and Fig. 24. Fig. 23 is a front view for explaining the internal configuration of the load transmission mechanism 1G, and Fig. 24 is a perspective view for explaining the internal configuration of the load transmission mechanism 1G. The load transmission mechanism 1G is a modified example of the load transmission mechanism 1B, is attached to the second training apparatus 201 when used, and receives input from the user's feet. In the following explanation of the load transmission mechanism 1G, only the differences from the load transmission mechanism 1B will be explained, and the points in common with the load transmission mechanism 1B will be given the same reference numerals as the load transmission mechanism 1B in Figures 23 and 24 and explanations thereof will be omitted.

[0107] The load transmission mechanism 1G is different from the load transmission mechanism 1B in the guide direction of the linear motion guide unit 20. The guide direction of the slider 20c of the linear motion guide unit 20 of the load transmission mechanism 1G is a direction vertical to the paper surface of Fig. 23 and a direction perpendicular to the extension direction of the transmission chain 10. Therefore, the extension direction of the first guide 20a and the second guide 20b of the linear motion guide unit 20 is a direction vertical to the paper surface of Fig. 23 and a direction perpendicular to the extension direction of the transmission chain 10.

[0108] Since the connecting and fixing part 23 is fixed to the slider 20c, the connecting and fixing part 23 moves back and forth horizontally in a direction perpendicular to the plane of the paper in Fig. 23. The driving shaft part 276 and the sliding shaft part 13 move horizontally together with the connecting and fixing part 23. The horizontal movement of the driving shaft part 276 is accompanied by a load because it pulls the tension member 25 connected to the sliding shaft part 13. In addition, the rotational movement of the driving shaft part 276 is accompanied by an axial displacement of the sliding shaft part 13, and further accompanied by a load because it pulls the tension member 25.

[0109] The top surface 22a of the housing 22 is provided with an elongated hole 34 through which the driving shaft 276 protrudes to the outside. The driving shaft 276 reciprocates inside the elongated hole 34 in the direction of arrow 276a. The top surface 22a of the housing 22 is also provided with an elongated hole 33 through which the sliding shaft 13 protrudes to the outside. The sliding shaft 13 reciprocates inside the elongated hole 33 in the direction of arrow 13d.

[0110] The rotational motion of the footrest 271 attached to the tip 276c of the main shaft 276 is transmitted as the rotational motion of the intermediate shaft bevel gear 5d via the transmission chain 10. The rotational motion of the intermediate shaft bevel gear 5d is transmitted to the orthogonal shaft bevel gear 6c which constitutes the second rotational transmission unit 1M together with the intermediate shaft bevel gear 5d. Since the rotational motion of the orthogonal shaft bevel gear 6c is subjected to a resistance force due to the load of the tension member 25 via the link mechanism unit 30 and the sliding shaft unit 13, a force that moves the intermediate shaft bevel gear 5d horizontally in the same direction as the rotational motion of the intermediate shaft bevel gear 5d acts on the intermediate shaft bevel gear 5d as a reaction to the rotational motion of the intermediate shaft bevel gear 5d. The force that moves the intermediate shaft bevel gear 5d horizontally acts on the main shaft 276 and the footrest 271 via the connecting and fixing unit 23.

[0111] Therefore, when the user rotates the foot placed on the footrest 271 clockwise, the footrest 271 moves horizontally to the right as seen by the user, with a load. On the other hand, when the user rotates the foot placed on the footrest 271 counterclockwise, the footrest 271 moves horizontally to the left as seen by the user, with a load. As a result, the user's legs move horizontally in the same direction as the rotational movement of the footrest portion 271, and therefore the user's legs undergo simultaneous rotational and lateral movement, enabling a complex exercise using multiple leg muscles. Furthermore, by adding flexion and extension of the legs placed on the footrest 271, the user's legs can simultaneously perform three-directional movements, namely rotational movement, lateral movement, and flexion and extension, thereby enabling a complex three-directional exercise using a wide range of the leg muscles.

[0112] <Configuration of the Load Transmission Mechanism 1H for Training Apparatus of the Eighth Embodiment> A load transmission mechanism 1H for a training tool according to an eighth embodiment (hereinafter referred to as the load transmission mechanism 1H) will be described with reference to Fig. 25. Fig. 25 is a front view for explaining the internal configuration of the load transmission mechanism 1H. The load transmission mechanism 1H is a modified example of the load transmission mechanism 1A and a modified example of the load transmission mechanism 1G, which is attached to the first training tool 100 and receives input from the user's hand. The load transmission mechanism 1G is mainly used for lower limb exercise and is attached to the second training tool 201, whereas the load transmission mechanism 1H is mainly used for upper limb exercise and is attached to the first training tool 100. In addition, the load transmission mechanism 1H is different from the load transmission mechanism 1G in the configuration of the drive shaft 4 from the drive shaft 276 (see Figs. 23 and 24) of the load transmission mechanism 1G. The drive shaft 4 differs from the load transmission mechanism 1G in that its tip protrudes from the side opposite to the sliding shaft 13 and the grip part 11 is connected to the tip. In the following description of the load transmission mechanism 1H, only the differences from the load transmission mechanism 1A will be described, and the points in common with the load transmission mechanism 1A will be given the same reference numerals as the load transmission mechanism 1A in FIG. 25 and the description thereof will be omitted.

[0113] The load transmission mechanism 1H is different from the load transmission mechanism 1A in the guide direction of the linear guide unit 20. The guide direction of the slider 20c of the linear guide unit 20 of the load transmission mechanism 1H is a direction perpendicular to the paper surface of Fig. 25 and perpendicular to the extension direction of the transmission chain 10. Therefore, the extension direction of the first guide 20a and the second guide 20b of the linear guide unit 20 is a direction perpendicular to the paper surface of Fig. 25 and perpendicular to the extension direction of the transmission chain 10.

[0114] The rotational motion of the grip part 11 attached to the tip of the main shaft part 4 is transmitted as the rotational motion of the intermediate shaft bevel gear 5d via the transmission chain 10. The rotational motion of the intermediate shaft bevel gear 5d is transmitted to the orthogonal shaft bevel gear 6c constituting the second rotation transmission part 1M. Since the rotational motion of the orthogonal shaft bevel gear 6c is subjected to a resistance force due to the load of the tension member 25 via the link mechanism part 30 and the sliding shaft part 13, a force that moves the intermediate shaft bevel gear 5d horizontally in the same direction as the rotational motion acts on the intermediate shaft bevel gear 5d as a reaction to the rotational motion of the intermediate shaft bevel gear 5d. The force that moves the intermediate shaft bevel gear 5d horizontally acts on the main shaft part 4 and the grip part 11 via the connecting and fixing part 23.

[0115] Therefore, for example, the user stands up and faces the front in the initial state of the load transmission mechanism 1H (see Figs. 8 and 9), and grips the grip 11 with the back of the hand facing the left and right outside of the first training tool 100. When the user rotates the grip 11 clockwise from this state as viewed from above, the grip 11 moves horizontally with a load in the same direction as the rotation, i.e., to the right as viewed from the user. On the other hand, when the user rotates the grip 11 counterclockwise from this state as viewed from above, the grip 11 moves horizontally with a load in the same direction as the rotation, i.e., to the left as viewed from the user.

[0116] As a result, the user's arm moves horizontally in the same direction as the rotational movement of the gripping portion 11, and therefore the user's arm undergoes simultaneous rotational and lateral movement, enabling a complex movement using multiple muscles in the arm. Furthermore, by adding a downward pulling motion to the arm, the user's arm can simultaneously perform three-way movements: rotational movement, lateral movement, and downward movement, thereby enabling the user to perform a three-way compound movement using a wide range of the arm muscles.

[0117] The present invention is not limited to the load transmission mechanism units for training equipment 1A, 1B, 1C, 1D, 1E, 1F, 1G, and 1H according to the above-described embodiments, and the training equipment 100, 201 using the same, but can be embodied in various other modified forms or application examples without departing from the gist of the present invention as set forth in the claims.
