Description

[Technical field]

[0001] The present invention relates to training equipment. [Background technology]

[0002] Conventionally, various types of training equipment have been available. For example, Patent Document 1 discloses a training equipment that allows both arms to be exercised. The training equipment disclosed in Patent Document 1 allows the user to obtain flexible and elastic shoulder and back muscles without hardening the muscles, with less strain on the body such as muscle pain and fatigue.

[0003] Incidentally, the training equipment described in the above Patent Document 1 can mainly train the muscles of the shoulders and back, but it is desirable to train in a well-balanced manner. Therefore, it is desirable to provide a training equipment for obtaining flexible and elastic muscles, etc., without hardening the muscles, with less strain on the body such as muscle pain and fatigue, for parts other than the above-mentioned parts. In addition, in recent years, there are more and more situations where people stay at home. Therefore, some people have training equipment at home, and such training equipment is required to be compact in size, but there is a problem that the training equipment is often large in size.

[0004] [Patent Document 1] JP 2006-187317 A Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been made in consideration of the above demand, and aims to provide a training device that can train parts of the body other than the shoulders and back, and that puts less strain on the body, such as causing muscle pain and fatigue. [Means for solving the problem]

[0006] In order to solve the above problems, a training device according to one embodiment of the present invention comprises a seating section for a user to sit on, a load-applying section, a cylindrical guide pillar extending vertically, a lifting section that is guided by the guide pillar and can move freely in the up and down direction and is connected to the guide pillar and can rotate freely, a grip section provided on the lifting section, a placement section for placing the soles of the user's feet, a slide rail, a sliding section that has the placement section and slides against the slide rail, and a tensioning member having one end connected to the lifting section and the other end connected to the sliding section, and that applies a load from the load-applying section to the lifting section and the sliding section.

[0007] In the above training device, the tension member may be connected to the load applying portion via a pulley.

[0008] In the above training device, the tension member may apply a load from the load application part in a vertically upward direction to the lifting part.

[0009] In the above-described training device, the slide rail may extend in a direction away from the seating portion, and the tension member may apply a load from the load application portion to the sliding portion in the direction in which the slide rail extends, on the side pulling the sliding portion toward the seating portion.

[0010] In the above training device, the grip portion may be connected to the lift portion via a first rotation shaft that is rotatably provided.

[0011] In the above training equipment, the sliding part may include a sliding part main body that slides against the slide rail, a second rotation shaft that is rotatably provided against the sliding part main body, a connecting plate that vertically connects the second rotation shaft, two side plates that are vertically connected to both ends of the connecting plate, and a third rotation shaft that connects the two side plates, and the placement part may be rotatably connected to the second rotation shaft.

[0012] In the above training equipment, the tensioning member may comprise a first tensioning member having one end connected to the lifting portion, a second tensioning member having one end connected to the sliding portion, and a connecting portion connecting the other end of the first tensioning member to the other end of the second tensioning member.

[0013] In the above training device, the first tensioning member may be an elastic wire, and the second tensioning member may be an elastic chain.

[0014] In the above-mentioned training apparatus, the seat, guide posts and slide rails may be provided at predetermined positions on a single framework, and the load-applying portion may consist of a weight supported on the framework so as to be freely movable up and down and to be freely connected and separated from each other.

[0015] In the above training equipment, the gripping unit is rotatably connected to the lifting unit via a fourth rotation axis, and the lifting unit may include a rotation transmission unit that transmits rotational motion of the gripping unit around the fourth rotation axis, and a crank mechanism unit that converts the rotational motion transmitted by the rotation transmission unit into up and down motion of a sliding shaft connected to one end of the tensioning member.

[0016] In the above training equipment, the sliding part may include a rotation transmission part that transmits rotational motion around the second rotation axis of the sliding part, and a crank mechanism part that converts the rotational motion transmitted by the rotation transmission part into sliding motion of a connection part that is connected to the other end of the tension member.

[0020] Hereinafter, a training device according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0021] <Embodiment Mode> <Configuration> Fig. 1 is a perspective view showing the appearance of the training device 1. As shown in Fig. 1, the training device 1 includes a seating section 10 on which a user sits, a load applying section 30 that applies a load, a cylindrical guide post 40 extending in the vertical direction, a lifting section 50 that is guided by the guide post 40 and is connected to the lifting section 50 so as to be movable up and down and rotatable, a gripping section 60 provided on the lifting section 50, a placement section 71 on which the sole of the user's foot is placed, slide rails 22a, 22b, a sliding section 70 that includes the placement section 71, and a tension member 80 that is connected at one end to the lifting section 50 and at the other end to the sliding section 70 and applies the load from the load applying section 30 to the lifting section 50 and the sliding section 70.

[0022] The training device 1 will be described in detail below with reference to the drawings. First, the structure of the training device 1 will be described with reference to Figs. 1 to 4. As described above, Fig. 1 is a perspective view of the training device 1, Fig. 2 is an enlarged view of the lifting / lowering section 50 and its surroundings, and Fig. 3 is an enlarged view of the sliding section 70 and its surroundings. Fig. 4 shows the manner in which the training device 1 is used, but the internal structure of the training device 1, including the configuration of the tension member 80, will be described with reference to this drawing.

[0023] As shown in FIG. 1, in the training apparatus 1, the seating section 10 is supported by a framework 20 which is a basic frame of the training apparatus 1. The framework 20 is the skeleton of the entire training apparatus 1 and serves to stably install the training apparatus 1 on the floor surface. The framework 20 can be formed by processing a rectangular pipe material or a plate material made of a material having a certain level of rigidity such as steel, aluminum, stainless steel, or resin, and fixing it by bolts, welding, or the like. The seating section 10 is composed of a seat 11 on which a user sits and a seat pillar 12 which supports the seat 11. The seat pillar 12 is fixed to the framework 20. The seat pillar 12 holds the seat 11. Although not shown, the seat pillar 12 has a through hole for passing a tension member 80 in the front-rear direction. The seat 11 is a place where a user of the training apparatus 1 sits, and as shown in FIG. 1, it is a rectangle that is long in the left-right direction of the training apparatus 1. This is to allow the user to sit on either the right or left side of seat 11, but as long as the user can sit comfortably, the shape does not have to be rectangular, and may be square or circular. Note that in this embodiment, the front, back, left and right of training apparatus 1 are defined with Fig. 4 being a front view and Fig. 6 being a left side view.

[0024] As shown in FIG. 1, the seating portion 10 may include a backrest 15 between the load applying portion 30 and the rear of the seat 11, for supporting the user's body during use.

[0025] The framework 20 is provided with a guide pillar 40 extending in the vertical direction. As shown in Fig. 1, the guide pillar 40 is provided in a position forward of the load applying portion 30 and rearward of the seating portion 10. As shown in Fig. 1, the framework 20 includes an upper housing 25 behind the guide pillar 40 for guiding the extension direction of the tension member 80 inside the framework 20. The guide pillar 40 has a lower end connected to the framework 20 and an upper end connected to the upper housing 25 for being fixed.

[0026] 1 and 2, the guide pillar 40 may be provided with a shock absorbing material 41. The shock absorbing material 41 is a member for absorbing the shock when the lifting / lowering unit 50 comes into contact with the upper housing 25 and the framework 20. The shock absorbing material 41 may be realized by, for example, rubber, sponge, or the like.

[0027] The lifting / lowering unit 50 shown in Figs. 1 and 2 is attached to the guide support 40. As shown in Figs. 1 and 2, the lifting / lowering unit 50 is attached to the guide support 40 so as to be vertically movable. Although not shown, the lifting / lowering unit 50 has a through hole for inserting the guide support 40. Therefore, the lifting / lowering unit 50 moves vertically along the guide support 40. The lifting / lowering unit 50 is attached to the guide support 40 so as to be rotatable relative to the guide support 40 with the guide support 40 as the central axis. Therefore, a certain level of rigidity is required for the guide support 40. Therefore, the guide support 40 may be made of stainless steel, for example.

[0028] 2, the lifting unit 50 includes a rotating shaft 64 rotatably connected to the bottom surface of the lifting unit 50, a U-shaped frame body 63 connected to the rotating shaft 64, and a gripping unit 60 rotatably connected to the frame body 63. The gripping unit 60 is a part that the user holds when exercising. The gripping unit 60 may be simply fixed to the frame body 63. That is, the gripping unit 60 does not need to be rotatable with respect to the frame body 63.

[0029] 2, a connection portion 80b for connecting with a tension member 80 (first tension member 80a) is provided on the upper surface of the lifting / lowering unit 50, and the tension member 80 is connected to the connection portion 80b. As will be described in detail later, the tension member 80 is connected to the load application portion 30, and an upward tension acts on the lifting / lowering unit 50 due to the load of the load application portion 30.

[0030] As shown in Fig. 1, the sliding part 70 of the training device 1 slides along slide rails 22a and 22b. The slide rail 22a is suspended from the frame 20 of the training device 1 and a frame 21 disposed in front of the frame 20, and is fixed at both ends. Fig. 3 is an enlarged view of the sliding part 70 and its surroundings in the training device 1.

[0031] As shown in FIG. 3, the sliding portion 70 includes a support portion 71, a bearing 72, a third rotating shaft 73, a side plate 74a, a side plate 74b, a connecting plate 75, a second rotating shaft 76, an upper main body portion 77, a lower main body portion 78, and a connecting portion 79.

[0032] 3, the sliding part 70 includes a lower body part 78 that slides freely on the slide rails 22a, 22b in the extension direction of the slide rails 22a, 22b, and an upper body part 77 that is connected to the lower body part 78 and provided on the lower body part 78. The upper body part 77 and the lower body part 78 are connected to each other to form a sliding part main body. The lower body part 78 sandwiches the slide rails 22a, 22b and slides along the slide rails 22a, 22b.

[0033] A second rotating shaft 76 is provided on the main body upper part 77 and is rotatably connected to the main body upper part 77. The second rotating shaft 76 is connected to a connecting plate 75. The connecting plate 75 is a flat plate-shaped member, and the second rotating shaft 76 is connected vertically to its center.

[0034] Flat side plates 74a, 74b are provided at both ends of the connecting plate 75 and connected perpendicularly to the connecting plate 75. A third rotating shaft 73 is connected perpendicularly to the side plates 74a, 74b so as to be rotatable.

[0035] The third rotating shaft 73 is connected by being sandwiched between the mounting portion 71 and the bearing 72. The bearing 72 has a bearing portion that is rotatably fitted to the third rotating shaft 73. This allows the mounting portion 71 to rotate around the third rotating shaft 73. The mounting portion 71 can also rotate around the second rotating shaft 76.

[0036] That is, the placement portion 71 can rotate around two mutually orthogonal different axes. Therefore, by providing the structure shown in Fig. 3, the user can place the sole of the foot on the placement portion 71 stress-free and push the sliding portion 70 with the foot at a desired angle. Therefore, the user can apply a load to himself, including his feet, with the training tool 1 in a form (angle or force) that he desires.

[0037] 3, a connection part 79 for connecting a tension member 80 is provided at the rear of the sliding part main body. Since the load application part 30 is connected to the tension member 80, tension based on the load of the load application part 30 acts on the sliding part 70.

[0038] Fig. 4 is a side view showing a first mode of the training tool in a first mode of use, but is also a diagram for explaining the configuration of tension member 80. Fig. 4 is also a diagram showing how tension member 80 is connected to load applying unit 30, lifting unit 50, and sliding unit 70.

[0039] As shown in FIG. 4, the tension member 80 is formed by connecting a first tension member 80a and a second tension member 80c with a connecting member 80d. The training tool 1 includes pulleys 85a-85h at the positions shown in the figure for regulating the moving direction of the tension member 80. One end of the first tension member 80a is connected to the lifting unit 50 via a connecting portion 80b, and the other end is guided by the pulleys 85a and 85b to connect to the connecting member 80d. One end of the second tension member 80c (see FIG. 3) is connected to the sliding unit 70 (see FIG. 3) via a connecting portion 79, and the other end is guided by the pulleys 85h, 85g, 85f, 85e, 85d, and the movable pulley 85c to connect to the connecting member 80d.

[0040] In this embodiment, the first tension member 80a is specifically made of a wire, and the second tension member 80c is made of a chain. The connecting member 80d is configured to connect to the chain (the second tension member 80c) on one side, and connects the first tension member 80a and the second tension member 80c by winding and joining the end of the wire (the first tension member 80a) on the other side. Note that the above connection method is an example, and other methods may be used. By making the first tension member 80a a wire, the load of the load applying unit 30 can be pulled while maintaining a certain strength, and the first tension member 80a can also be stretched in the lateral direction relative to the extension direction, so that the lifting unit 50 can perform up and down movement along the guide post 40, as well as rotational movement centered on the guide post 40. In addition, by making the second tension member 80c a chain, the load of the load applying unit 30 can be pulled by a material having a higher rigidity than a wire, so that the durability of the training tool 1 can be improved.

[0041] The tension member 80 (second tension member 80c) is connected to the load application unit 30 via a movable pulley 85c. Since the load from the load application unit 30 is applied to the tension member 80 via the movable pulley 85c, the tension member 80 will not slacken regardless of the state of the lifting unit 50 (whether it is pulled down by the user or not) and regardless of the state of the sliding unit 70 (whether it is pushed by the user or not).

[0042] As shown in FIG. 1, the load applying section 30 is composed of a pair of cylindrical weight guide posts 32 (only one of which is shown in FIG. 1 due to space restrictions) whose top and bottom are fixed to the frame 20, and a weight configured to be movable up and down relative to the weight guide posts 32. The weight is provided with a through hole for inserting the weight guide posts 32. The load applying section 30 may be configured to adjust the magnitude of the load to be applied, and specifically, the weight serving as the weight member may be a plate-like member, and the load may be adjusted by changing the number of plates. Therefore, the load applying section 30 may be provided with a clamp (not shown) that allows the weights to be connected and separated from each other. By making each of the plate-like members of the weight a fixed weight, the magnitude of the load can be changed in stages. In addition, the weight guide posts 32 may be provided with an impact absorbing material 31 that suppresses the weight from colliding with the frame 20 with an impact greater than a certain level.

[0043] Therefore, when the lifting / lowering unit 50 descends or when the sliding unit 70 slides toward the front of the training apparatus 1, the tension member 80 is pulled, and the movable pulley 85c rises vertically upward, thereby pulling up the weight of the load application unit 30. At this time, the load of the load application unit 30 is applied upward to the lifting / lowering unit 50 or toward the rear of the sliding unit 70. As a result, a load can be applied to the arm of the user attempting to lower the lifting / lowering unit 50 via the grip unit 60, or to the foot of the user attempting to push the sliding unit 70.

[0044] Here, the configuration and function of the lifting / lowering unit 50 will be described with reference to the schematic perspective view of Fig. 17. One end of the lifting / lowering unit 50 is fitted to the guide post 40 so as to be movable up and down and rotatable horizontally. The lifting / lowering unit 50 is provided with a cylindrical guide part 54 that opens vertically at one end of a frame 53 that is covered from above by a box-shaped cover 52. Fitting the guide part 54 into the guide post 40 allows the lifting / lowering unit 50 to move up and down relative to the guide post 40 and to rotate horizontally around the guide post 40.

[0045] The gripping part 60 is held by the user in his / her hand, and is connected to the shaft 51 fixed to the other end of the lifting part 50 and rotatably provided below the lifting part 50. The gripping part 60 includes a handgrip part 61 on which the user places the fingers of the hand, a hand backing part 62 on which the back of the hand is placed, and a frame body 63 that supports the handgrip part 61 and the hand backing part 62. The handgrip part 61 is cylindrical in shape and the fingers of the hand except the thumb are placed on the handgrip part 61. The hand backing part 62 is cylindrical in shape and is covered with a cushioning material on the periphery thereof, and is placed on an appropriate position below the handgrip part 61 to protect the back of the hand (back of the hand) or the back of the wrist of the user who places the fingers on the handgrip part 61. The frame body 63 supports and fixes the handgrip part 61 and the hand backing part 62 at both ends, and the shaft 51 is fixed to the upper surface of the frame body 63. The shaft 51 is axially supported by the lifting section 50 via bearings provided on the upper and lower walls of a frame 53 of the lifting section 50. This allows the gripping section 60 to rotate about its axis in the horizontal direction relative to the lifting section 50.

[0046] Furthermore, the load transmission unit 90 provided in the lifting unit 50 is connected to the connection unit 80b of the tension member 80 in the lifting unit 50 so as to apply a load to the rotation of the gripping unit 60 about the axis 51 by the load applying unit 30. As can be seen from FIG. 17, the load transmission unit 90 includes a rotation transmission unit 91 (reference numerals 91a, 91b, 91c, 91d, and 91e in the figure) that transmits the rotational motion of the gripping unit 60 about the axis 51, and a crank mechanism unit 92 (reference numerals 92a and 92b in the figure) that converts the rotational motion transmitted by the rotation transmission unit 91 into vertical motion of the sliding shaft 57 connected to the connection unit 80b side of the tensioning member 80. By rotating the gripping unit 60 about its axis relative to the lifting unit 50, the sliding shaft 57 moves up and down via the rotation transmission unit 91 and the crank mechanism unit 92, and the weight of the load applying unit 30 connected by a clamp moves up and down.

[0047] More specifically, the rotation transmission unit 91 includes a sprocket 91a provided on the shaft 51 of the gripping unit 60 in the lifting unit 50, a sprocket 91b provided on a shaft whose upper and lower ends are journalled to the frame 53, a chain 91c hung on the sprockets 91a and 91b, a bevel gear 91d provided on the shaft on which the sprocket 91b is provided, and a bevel gear (crown gear) 91e meshing with the bevel gear 91d. The bevel gear 91e is provided on the free end of the crankshaft 92a journalled horizontally to the frame 53 on the gripping unit 60 side. As a result, the crankshaft 92a rotates in the horizontal direction in response to the rotation of the shaft 51 of the gripping unit 60.

[0048] The crank mechanism 92 includes a crank shaft 92a and a connecting piece 92b, one end of which is rotatably connected to a projection protruding from the center of the crank shaft 92a and the connecting piece 92b, the connecting piece 92b being rotatably connected to the lower end of the sliding shaft 57 at the connecting portion 80b. As a result, the sliding shaft 57 moves up and down by the rotation of the crank shaft 92a. In this manner, the gripping portion 60 is rotationally biased by a force proportional to the load of the load applying portion 30. Then, by axially rotating the gripping portion 60 against the rotation biasing force relative to the lifting portion 50, the sliding shaft 57 slides downward relative to the lifting portion 50 (i.e., the sliding shaft 57 and the tension member 80 connected to the sliding shaft 57 are pulled into the lifting portion 50), and the weight of the load applying portion 30 connected by the clamp is pulled up.

[0049] The internal structure of the sliding part 70 is also substantially the same as that shown in FIG. 17. Although the explanation of the drawings is omitted, a placement part 71 is provided at the position where the grip part 60 in FIG. 17 is provided, and the configuration corresponding to the guide pillar 40 is the slide rails 22a and 22b. On the other hand, unlike the lifting part 50, in the sliding part 70, a connection part 79 corresponding to the sliding shaft 57 is provided at the opposite position to that shown in FIG. 17 (the opposite side to the surface where the sliding shaft 57 is provided in FIG. 17). However, in the sliding part 70, as in the lifting part 50, a crank mechanism is used, and when the user rotates the placement part 71 on which the user places his / her foot, the crank mechanism rotates, and the connection part 79 and the tension member 80 to which the connection part 79 is connected are pulled into the sliding part 70, and the weight of the tension member 80 and the load applying part 30 connected thereto are pulled up. That is, the rotational motion of the mounting portion 71 is converted into a sliding motion of the connecting portion 79 relative to the sliding portion 70, thereby lifting the weight of the tension member 80 and the load applying portion 30 to which the tension member 80 is connected.

[0050] <First usage form> 4 to 7 are diagrams showing an example of exercise in a first mode of use of the training tool 1. FIG. 4 is a left side view showing a first aspect of the first mode of use of the training tool. FIG. 5 is a left side view showing a second aspect of the first mode of use of the training tool. FIG. 6 is a front view showing the first aspect of the first mode of use of the training tool. FIG. 7 is a front view showing the second aspect of the first mode of use of the training tool. That is, FIG. 6 corresponds to FIG. 4, and FIG. 7 corresponds to FIG. 5.

[0051] The first usage mode shows an example in which the user exercises his / her arms. Although this is arm exercise, the user can also train various parts of their body (for example, muscles around the shoulders and waist) in conjunction with the arms.

[0052] 4 and 6 show the initial state when exercising in the first usage mode. That is, Fig. 4 and Fig. 6 show the state in which the user is seated on the training device 1 in the state shown in Fig. 1. As shown in Fig. 4 and Fig. 6, the user sits on the right side of the training device 1, that is, on the right side of the seat 11. That is, the user sits on the seat 11 with the sliding part 70 facing forward and with the backrest 15 at his / her back. Then, as shown in Fig. 4 and Fig. 6, the user holds the grip part 60 with his / her left hand.

[0053] From this state, the user pulls the lifting unit 50 downward via the grip 60 while rotating the entire arm towards the rear of the user.

[0054] As a result, as shown in Figures 5 and 7, the user rotates his / her body (left arm) while pulling the lifting / lowering unit 50 until his / her elbow is at approximately 90 degrees (not limited to 90 degrees). This can be achieved by configuring the lifting / lowering unit 50 to be rotatable relative to the guide post 40. Although not shown, the pulley 85a is provided with a member for keeping the tension member 80 engaged with the groove of the pulley 85a, so that the tension member 80 will not come off the pulley 85a even if it is pulled in the direction shown in Figure 7.

[0055] 5 and 7, the user returns the lifting / lowering unit 50 to its original position. At this time, it is desirable to return the lifting / lowering unit 50 at a constant speed. That is, in the first usage mode, the postures between those shown in Figs. 4, 6 and those shown in Figs. 5 and 7 are repeated a predetermined number of times.

[0056] During this series of processes, the load of the load applying unit 30 is applied vertically upward to the tensile member 80 between the lifting / lowering unit 50 and the upper housing 25. Therefore, the force of the user trying to lower the lifting / lowering unit 50 and the force of the load of the load applying unit 30 trying to pull the lifting / lowering unit 50 upward are opposed to each other, so that the user can train the muscles of their arms, shoulders, waist, etc. according to the weight of the weight applying unit 30.

[0057] Specifically, the user, from a state where the gripping part 60 is being gripped, twists the upper arm of the arm gripping the gripping part 60 (the left arm in the case of Figs. 4 to 7; hereinafter, the left arm will be used, but the same applies to the opposite arm) outward against a force proportional to the load of the load applying part 30 that is rotating and biasing the gripping part 60 to face the front direction (the state shown in Fig. 1) so that the back of the hand of the gripping part 60 faces the back direction of the user. In this state, both the flexor and extensor muscles are relaxed, and the shoulders and arms can be in a relaxed state. In addition, the gripping part 60 (the lifting and lowering part 50) is biased upward by the load of the load applying part 30, and the surrounding muscles including those near the shoulder girdle are appropriately "stretched" (the state shown in Figs. 4 and 6).

[0058] Next, the user bends the left arm against the load of the load application unit 30 to "shorten" the muscles and pull down the grip unit 60 so that the muscles around the shoulder girdle, etc., which have been moderately "stretched," cause a reflex. That is, in the process of transitioning from the state shown in FIG. 4 (FIG. 6) to the state shown in FIG. 5 (FIG. 7), the muscles can be gradually "shortened." At this time, the weight of the load application unit 30 is pulled up by rotating the grip unit 60 in the horizontal direction outward relative to the lifting / lowering unit 50 by twisting the upper arm outward, thereby reducing the load in the initial movement of pulling down the left arm and creating a "relaxed" state. That is, when using the left arm to pull down the lifting / lowering unit 50, the grip unit 60 is rotated to cause the sliding shaft 57 to retract into the lifting / lowering unit 50 in conjunction with the rotation of the crank mechanism 90 in the lifting / lowering unit 50, thereby reducing the load on the left arm compared to when this mechanism is not present, and creating a "relaxed" state in the left arm. That is, in the state shown in FIG. 5 (FIG. 7), "relaxation" can be generated.

[0059] In addition, when the user bends the left arm to pull down the gripping part 60, the user gradually spreads the left arm outward so that the lifting / lowering part 50 faces outward (toward the back of the user) against the force that rotates the lifting / lowering part 50 to face the front direction. The force that rotates the lifting / lowering part 50 to face the front direction is approximately inversely proportional to the distance between the contact point between the pulley 85a and the tension member 80 (80a) and the lifting / lowering part 50, so that the resistance to spreading the left arm outward (toward the back of the user) decreases as the left arm is bent to pull down the gripping part 60. Therefore, when the user bends the left arm to pull down the gripping part 60, the user can smoothly perform the action of gradually spreading the left arm outward while pulling down the gripping part 60 by outputting approximately constant muscle force to spread the left arm outward, and it becomes possible to prevent muscle contraction.

[0060] Next, the user pulls down the gripping part 60 to about shoulder height, and then twists the left arm inward while following the biasing force of the load applying part 30, and closes the left arm inward while stretching the left arm, slowly returning the gripping part 60 to the state in which it was initially gripped (the state shown in Figs. 4 and 6). That is, in the process of returning from the state shown in Fig. 5 (Fig. 7) to the state shown in Fig. 4 (Fig. 6), the muscles are gradually "stretched", and reach the most "stretched" state in the state shown in Fig. 4 (Fig. 6). This completes one cycle of the exercise shown in Figs. 4 to 7. The user repeats this cycle for the number of floors appropriate for him / her. In this way, in the exercise using the training tool 1, the left arm is bent and the gripping part 60 is pulled down to "shorten" the muscle, and then the upper arm is twisted outward to "relax" the muscle, and in the process of returning the gripping part 60 to its original position, an "extension" motion is added, so that each muscle group can obtain the timing of "relaxation-extension-shortening", and can perform the motion in good coordination, and the user can obtain flexible and elastic muscles. The start position for the exercise may be the state of FIG. 4 or the state of FIG. 5, but it is preferable to start the exercise from a state where relaxation has occurred. The exercise may be started from either position, as long as the exercise including the cycle of "relaxation-extension-shortening" is repeated.

[0061] The training tool 1 is capable of appropriately training the muscles of the shoulders and back by initial load training (registered trademark). Initial load training is defined as "training that utilizes the body change to a position where a reflex occurs and the accompanying change in the center of gravity position, etc., to promote the series of movement processes of relaxation-stretching-contraction of the agonist muscle, while preventing the co-contraction of the antagonist muscle and the muscles acting antagonistically." It is completely different from final load training, which applies load to the end and enlarges the muscle while keeping the muscle in a state of tension (hardening). Initial load training requires 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 muscle output. There is a problem that it is difficult to take appropriate movements and forms due to the balance of the body at the current stage and partial hardening, but this training tool 1 easily induces training with an ideal series of movements and form.

[0062] Initial load training using this training device 1 allows for "inter-segmental force transmission from the center (body trunk) to the extremities", in other words, it relaxes the human muscles, which have the characteristic of contracting without stretching on their own, and applies an appropriate load to the muscle spindle-tendon organs, which are sensory receptors, inducing the exertion of force when the muscle shortens from a moderately stretched or passively stretched point, and by gradually decreasing the load instantly and continuously, it is possible to achieve an active state in which other muscles in the human body, which have been said to be the only muscles that do not contract together like the cardiac muscle, do not contract together, and it becomes possible to promote and develop neuromuscular control.

[0063] The initial load training using this training device 1 is a training that uses the load of the training device 1 to cause a reflex in the muscles, making the muscles that should be working work well and improving the functions of the muscles and nerves, and uses the load 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.

[0064] Although not shown, the user can also exercise his / her right arm by sitting on the left side of the training apparatus 1, opposite the seat 11 in Figures 4 to 7, i.e., by sitting on the seat 11 with the sliding part 70 on his / her right side and the backrest 15 on his / her left side.

[0065] Therefore, the user can perform rotational exercises around the shoulders and waist symmetrically while training both arms, thereby expanding his or her own range of motion.

[0066] Furthermore, by using a structure that trains one arm at a time instead of both arms, there is no need to prepare a lifting section 50 to train both arms at once, so the size can be made more compact than if the training device 1 were configured to accommodate both arms (the width can be narrower than if two lifting sections 50 were provided for both arms), and the area of ​​the space that needs to be prepared as installation space for the training device 1 can be reduced.

[0067] <Second usage form> The first usage mode described above shows an example of exercising the arms, whereas the second usage mode describes an example of the user exercising the legs using the training device 1. Although this is leg exercise, it is possible to train various parts of the user that are linked to the legs.

[0068] 8 to 10 are left side views showing an example of exercise in the second usage mode, in which the user is exercising his / her legs.

[0069] As shown in Fig. 8, the user sits on the right side of the training device 1, i.e., on the right side of the seat 11. That is, the user sits on the seat 11 with the sliding part 70 on the left side and the backrest 15 on the right side. Then, as shown in Fig. 8, the user places the left leg on the rest part 71 of the sliding part 70 with the knee bent.

[0070] From this state, the user extends the left leg and pushes the sliding part 70. Then, as shown in Fig. 9, the sliding part 70 slides along the slide rails 22a, 22b. At this time, a load is applied to the sliding part 70 from the load application part 30 connected to the tension member 80 connected to the connection part 79 toward the rear of the training apparatus 1 (to the left on the paper in Figs. 8 to 10).

[0071] Then, from the state in which the legs are stretched as shown in Fig. 9, the sliding part 70 is slowly slid back to the original position along the slide rails 22a, 22b. This movement is repeated a certain number of times. In other words, the user repeats the posture between Fig. 8 and Fig. 9 a predetermined number of times.

[0072] As shown in Fig. 10, the user may twist the waist further than in the state shown in Fig. 9 and push the sliding part 70 farther, and in that case, the user may train the waist while stretching the legs. This posture is possible because the placement part 71 is configured to be rotatable relative to the sliding part body. The user may perform leg stretching exercises between Fig. 8 and Fig. 9, or may perform leg stretching exercises between Fig. 8 and Fig. 10.

[0073] Also, although not shown, in the second mode of use, the user can also exercise with his / her right leg by sitting on the left side of the training apparatus 1, opposite the seat 11 in Figures 8 to 10, i.e., by sitting on the seat 11 with the sliding part 70 on his / her right side and the backrest 15 on his / her left side.

[0074] Therefore, the user can rotate around the waist while strengthening both legs symmetrically. Specifically, the user spreads his / her legs and pushes off the sliding part 70 as if kicking it. This is a good example for strengthening the muscles around the hip joints, around the pelvis, thighs, knees, etc.

[0075] In this second usage form, as in the case of the arms described above, each muscle group of the legs can achieve the timing of "relaxation-stretch-contraction" and perform movements with good coordination. Specifically, in the state shown in Fig. 8, the left leg is not loaded by the load application unit 30, and the muscles are in a "stretched" state. In addition, the state shown in Fig. 8 is also a state in which the foot is simply placed on the support unit 71, and the overall state is relaxed, so it can also be said to be a "relaxed" state.

[0076] From this point, the user applies force to the foot to push the sliding part 70 to which the load is being applied by the load application part 30. That is, in the process shown in FIG. 8 to FIG. 9 or FIG. 10, the load of the load application part 30 is applied to the left leg of the user, and a "contracted" state can be generated in the muscles of the left leg of the user. Then, in the state shown in FIG. 9 or FIG. 10, by rotating the placing part 71 relative to the sliding part 70, the internal crank mechanism pulls the connecting part 79 into the sliding part 70, thereby reducing the load applied to the foot by the load application part 30. That is, in the state in which the sliding part 70 is rotated as shown in FIG. 9 or FIG. 10, a "relaxed" state can be generated in the user's foot.

[0077] Then, by returning the foot from the state shown in FIG. 9 or FIG. 10 to the state shown in FIG. 8 during the process shown in FIG. 8, a "stretched" state of the muscle can be produced.

[0078] Therefore, by moving the sliding part 70 from the state shown in Fig. 8 to the state shown in Fig. 9 or Fig. 10 and repeating the cycle of movement back to the state shown in Fig. 8, the timing of "relaxation-extension-contraction" can be generated, and movement can be performed with good interlocking. As for the leg movement, the state shown in Fig. 8 may be set as the initial state, or one cycle of movement may be performed with the state shown in Fig. 9 or Fig. 10 as the initial state, but since it is desirable to start the movement from a "relaxed" state as with the arm movement, it is desirable to start the movement from the state shown in Fig. 9 or Fig. 10 with the help of others.

[0079] In addition, by adopting a structure for training one leg at a time instead of both legs, there is no need to prepare a sliding part 70 for training both legs at once, so the size can be made more compact than when the training tool 1 is configured to accommodate both legs (the width can be narrower than when two sliding parts 70 are provided for both arms), and the area of ​​the space to be prepared as an installation space for the training tool 1 can be made smaller. In the exercises shown in Figs. 8 to 9, the user may exercise by sitting on the seating part 10 with the sliding part 70 facing the training tool 1 and with the backrest 15 at his / her back. That is, only the leg exercise may be performed in the usage form shown in Figs. 11 and 12. By changing the orientation of the body, the user can train different parts of himself / herself.

[0080] <Third usage form> The first usage mode is an example of exercising the arms, and the second usage mode is an example of exercising the legs, but these can also be performed simultaneously. Hereinafter, a description will be given with reference to the drawings.

[0081] 11 and 12 show a first example of the third usage form. FIG. 11 shows a state in which the user extends his / her left arm, grasps the gripping part 60 with the left hand, bends the left leg, and places the left foot on the placement part 71. From this state, the user lowers the lifting part 50 while bending the left arm and rotating the waist, as shown in the first usage form. At the same time, the user pushes the sliding part 70 while extending the left leg, as shown in the second usage form, to slide it along the slide rails 22a and 22b. As a result, the user takes a posture in which the left arm is bent and the left leg is extended, as shown in FIG. 12. Then, the user slowly returns to the posture shown in FIG. 11. The user repeats the postures shown in FIG. 11 and FIG. 12 a certain number of times. This allows the user to exercise the arms and the legs at the same time.

[0082] 13 and 14 show a second example of the third usage form. In the first example, when either the arm or the leg is stretched, the other is bent, whereas in the second example of the third usage form, the arms and legs are stretched in conjunction with each other, that is, when the arms are bent, the legs are bent, and when the arms are stretched, the legs are stretched.

[0083] In the third usage mode, similarly to the first and second usage modes, the user can sit on the left side of the training apparatus 1 and train the arm or leg on the opposite side.

[0084] <Supplementary Information> The training tool 1 according to the above embodiment is not limited to the above embodiment, and may be realized by other methods. Various modified examples will be described below.

[0085] (1) In the above embodiment, the tensioning member 80 is formed by joining two members, the first tensioning member 80a and the second tensioning member 80c, but the tensioning member 80 may be formed as a whole from a single member. For example, the tensioning member 80 may be formed only from a wire or only from a chain. By forming the entire tensioning member 80 from a single member, the durability of the tensioning member 80 can be improved, and the process of joining the first tensioning member 80a and the second tensioning member 80c during production can be omitted.

[0086] (2) The number and arrangement of pulleys shown in Figure 4 may be other than those shown in Figure 4, as long as the load of the load-applying unit 30 is appropriately applied to the sliding unit 70 and the lifting unit 50 in the direction described above.

[0087] (3) Although not shown in the above embodiment, the seating portion 10 may be provided with a height adjustment unit capable of adjusting the height of the seat 11 relative to the seat support pillar 12. As an example, the height adjustment unit may be realized as follows. That is, an internal pillar perpendicular to the seat 11 is provided, and the seat support pillar 12 is made hollow. Then, the internal pillar is inserted into the seat support pillar 12. The seat support pillar 12 and the internal pillar are each provided with a plurality of side holes that can face each other on their side surfaces. Then, one of the plurality of side holes provided in the seat support pillar 12 and one of the plurality of side holes provided in the internal pillar are opposed to each other, and height adjustment posts are inserted into both of the opposed side holes to adjust the height. This allows the height of the seat 11 to be adjusted, so that a training tool 1 that can be used by users of any physique and ability can be provided.

[0088] In the above embodiment, the seat 11 of the seating portion 10 may be configured so that its position can be adjusted not only in the height direction but also in the horizontal direction. This will be described with reference to FIG.

[0089] As shown in Fig. 15(a) and Fig. 15(b), the seat 11 may be configured to be movable toward the right side or the left side of the training apparatus 1. That is, the seating portion 10 may be provided with a sliding mechanism (not shown) so that the seat 11 can slide in the left-right direction with respect to the seat support 12 between the state of Fig. 15(a) and the state of Fig. 15(b). As an example of the sliding mechanism, a sliding rail may be provided on the back surface of the seat 11, and a fitting member that slidably fits with the sliding rail may be provided on the top surface of the seat support 12, but this is not limited thereto. The fitting member may also be provided with a slide lock for locking the slide. By being able to slide the position of the seat 11 in the left-right direction, users of various body types can use the training apparatus, and the load applied to the user can be changed depending on the position of the seat 11 and the way the user sits, so that the parts to be trained can be changed even with the same exercise.

[0090] The seat 11 may be configured to be rotatable around the seat pillar 12. That is, the seat 11 may be configured to be able to transition from the state shown in FIG. 15(a) to the state shown in FIG. 15(c) and further to the state shown in FIG. 15(b). Specifically, the seat pillar 12 may be hollow, and the seat 11 may be provided with a cylinder that can be inserted into the seat pillar 12, and the cylinder may be inserted into the seat pillar 12 to rotate the seat. The rotation mechanism is not limited to this. The direction of rotation may be from FIG. 15(b) to FIG. 15(c) and from FIG. 15(c) to FIG. 15(a). With this configuration, when the training tool 1 is not in use, the training tool 1 can be slimmed down as a whole by setting it to the state shown in FIG. 15(c), and the space can be effectively utilized.

[0091] (4) In the above embodiment, the slide rails 22a, 22b may be configured to be extendable and retractable as long as the sliding portion 70 is configured to be slidable. Alternatively, the slide rails 22a, 22b may be rails configured by connecting a plurality of parts together, and in this case, the length of the slide rails 22a, 22b may be adjusted by adjusting the number of the parts. This allows users with various leg lengths to be accommodated, and allows the training tool 1 to be stored in a compact size.

[0092] (5) Although not specifically described in the above embodiment, the support portion 71 may be provided with a fixing member for preventing the user's feet from coming off the support portion 71 when the user places the feet on the support portion 71. For example, the fixing member may be a band or the like, and may be configured to fix the user's feet to the support portion 71 by binding the feet with the band when the user places the feet on the support portion 71.

[0093] (6) In the above embodiment, the load applying unit 30 applies a load using a weight formed by stacking multiple plate-like heavy objects, but the load does not have to be applied simply by a heavy object. For example, a mechanism utilizing electromagnetic force, hydraulic pressure, pneumatic pressure, etc. may be used.

[0094] (7) In the above embodiment, the user sits on the seat 11 of the seat 10, but it is not essential that the user sits on the seat 10. As shown in Figs. 16(a) and 16(b), the training device 1 can also be used while standing to the side. In Fig. 16(a), the user stands on the right side of the training device 1 and holds the grip 60 with the left hand. Then, as shown in Fig. 16(b), the user pulls the grip 60 from there to lower the lifting unit 50. Then, the user repeats the posture between Fig. 16(a) and Fig. 16(b). In Figs. 16(a) and 16(b), the user maintains a standing state, but the user may further open his / her legs and lower his / her entire body. By doing so, not only the arm exercise but also the leg-splitting exercise can be performed while stretching the Achilles tendon. Also, in Figs. 16(a) and 16(b), the user has his / her right leg forward and his / her left leg backward, but this may be reversed. That is, the arm exercise may be performed with the left leg forward and the right leg backward. This exercise can also be performed for the right arm by standing on the left side of the training tool 1.

[0095] (8) The above embodiments and supplementary notes may be combined as appropriate. [Explanation of symbols]
