Description

Technical Field

[0001] The present invention relates to a training device. More specifically, it relates to a training device for performing muscle strength training.

Background Art

[0002] In many muscle strength trainings, as a configuration using an elastic body, a rubber band whose tension when pulled serves as a load is used. In training using a rubber band, since the material is rubber, it deteriorates and there is a risk of suddenly breaking during training. Also, it is often used by tying rubber, which takes time to prepare. Instead of this, as a mechanically configured one, a rope winding device that winds a rope body such as a drum biased by a spring is used. For example, Patent Document 1 describes a health promotion device including a drum housed in a case body and biased around a shaft by a spring, and a handle portion provided at one end of a rope wound by the drum. According to the health promotion device described in Patent Document 1, a user can promote health by repeatedly performing an exercise of gripping the handle portion and pulling out and then returning the rope from the case body against the load.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, with training using rubber bands, the rubber material deteriorates and there is a risk of it suddenly breaking during training, requiring regular replacement. Also, since the rubber is often used by tying knots, changing the band when changing the load takes time and preparation is cumbersome. Furthermore, according to the health promotion device described in Patent Document 1, a U-shaped member attached to the main body is suspended from an arm body such as a metal frame by a hook or the like. As a result, the orientation of the main body changes depending on the direction in which the user pulls the rope, making it impossible to pull the rope in the direction required for training, thus preventing effective training.

[Figure 10] This is a side view of the fixed part of the training device 1 according to the sixth embodiment of the present invention. [Modes for carrying out the invention]

[0033] Next, a first embodiment of the present invention will be described with reference to Figures 1 to 3.

[0034] [Overall configuration of training device 1] Figure 1 is a perspective view of a training device 1 according to a first embodiment of the present invention. Figure 2 is a perspective view of the base 38 of Figure 1, viewed from the back. Figure 3 is a schematic diagram showing the inside of the main body 10 of the training device 1.

[0035] The training device 1 consists of a main body 10, an angle adjustment unit 20, and a fixing unit 30.

[0036] The main body 10 houses a wire 12 as a string-like member inside and is capable of automatically winding up the wire 12 when it is pulled out from the main body 10. The main body 10 is equipped with the wire 12, a pull-out section 121 shown in Figure 3 provided at one end of the wire 12 for pulling the wire 12 out of the main body 10, a winding section 141 provided at the other end of the wire 12 for winding the wire 12 into the main body 10, and a load-applying section 14 that applies a load to the pull-out section 121 during the operation of pulling the wire 12 out of the main body 10.

[0037] The angle adjustment unit 20 shown in Figure 1 is located below the main body 10 and is integrally connected to the main body 10. It is provided so that the mounting angle of the main body 10 with respect to the fixed member 8 can be arbitrarily changed by rotating the main body 10 in the vertical direction.

[0038] According to this, since the angle adjustment unit 20 is installed below the main body, the main body 10 can be rotated to adjust the installation angle of the main body 10 with respect to the fixed member 8, allowing for smooth movement from a horizontal to a vertical position. Because the angle adjustment unit 20 is installed, the movement angle of the main body 10 is not restricted, there is no interference with the wire 12, and the angle of the main body 10 can be easily adjusted to the angle desired by the user.

[0039] The fixing part 30 is located below the angle adjustment part 20 and is integrally connected to the angle adjustment part 20. It provides fixing means for fixing the entire device, including the main body 10 and the angle adjustment part 20, to the fixed member 8. In one embodiment of the present invention, the fixing means includes suction cups 36a and 36b that fix the main body 10 to the fixed member 8 by negative pressure. The fixed member 8 is the object to which the training device 1, including the main body 10 and the angle adjustment part 20, is fixed by the fixing part 30. For example, it refers to an object arbitrarily selected by the user from flooring, desks, tables, workbenches, beds, bed frames, etc. In Figure 1, the fixed member 8 is shown as flooring as an example.

[0040] According to this, since the main body 10 is equipped with a fixing part 30 for fixing to the fixed member 8, it can be used with stable mounting in various locations.

[0041] Next, we will specifically describe the three mechanical components of training device 1.

[0042] [Main unit 10] The main body 10 is more specifically equipped with a wire 12, a winding section 141 having a winding body 13 for winding the wire 12 inside the main body 10, and a load-applying section 14 that applies a load to the winding body 13 by applying a load to the winding section 121 during the operation of pulling out the wire 12 from the main body 10. The main body 10 also includes a case 101 that houses the winding body 13, supports the central axis 131 which is the winding center of the winding body 13, and has an inlet / outlet 102 through which the wire 12 passes in and out as it is pulled out and wound up. The winding body 13 is connected to the other end of the wire 12 and is configured to rotate freely in the forward and reverse directions with the central axis 131 as the center of rotation.

[0043] An auxiliary roller 16 is further installed inside the case 101 of the main body 10. The auxiliary roller 16 is intended to ensure that the load applied to the draw-out section 121 by the load-applying section 14 is perpendicular to the opening surface of the inlet / outlet 102. The auxiliary roller 16 is installed between the central axis 131 of the winding body 13 and the inlet / outlet 102 through which the wire 12 is drawn out of the main body 10. The auxiliary roller 16 contacts the wire 12 from the side on or near the straight line connecting the central axis 131 of the winding body 13 and the inlet / outlet 102. By the auxiliary roller 16 contacting the wire 12 from the side, the direction in which the wire 12 is drawn out of the main body 10 is changed to a direction perpendicular to the opening surface of the inlet / outlet 102. The auxiliary roller 16 has its central axis 161, which is its center of rotation, supported by the case 101, and constantly presses the wire 12 toward the center of the winding body 13. Furthermore, the string-like component can be a string, rope, cable, or the like, in addition to the wire 12.

[0044] The case 101 houses a winding body 13 for winding the wire 12. The case 101 comprises a thin disc-shaped portion and a tapered portion that protrudes tapered from the disc-shaped portion. At the tip of the tapered portion of the case 101, a circular opening 102 is formed, which communicates with the inside of the case 101, through which the wire 12 is inserted, pulled out, and wound up. The opening 102 serves as the entrance and exit for the wire 12.

[0045] As shown in Figure 3, the pull-out section 121 consists of a handle 17 as a gripping section installed at one end of the wire 12, an elastic body 19 for shock absorption provided at the opening 102 of the case 101, and a stopper 18 that abuts against the elastic body 19 when the wire 12 is wound inside the main body 10. The gripping section may also be replaced with an annular member made of synthetic fiber, metal, cloth, rubber, etc., instead of the easy-to-grip handle 17, and may have a polygonal shape such as a hook, ellipse, or triangle. The gripping section may be configured to be attached to any of the four limbs of a person, such as the upper limb, upper arm, forearm, shoulder, elbow, wrist, fingers, foot, lower limb, thigh, lower leg, ankle, knee, or toes. Note that in Figures 1, 2, 5, 7, 8, and 9, the handle 17 installed at one end of the wire 12 is omitted in each drawing.

[0046] The load-applying section 14 is equipped with a coil spring 15. When winding the wire 12 into the main body 10, the winding body 13, which rotates around the central axis 131, is biased in one direction around the central axis 131 by the restoring force of the coil spring 15, that is, in the direction in which the wire 12 is wound into the main body 10.

[0047] The winding body 13 is a cylindrical component that winds the wire 12. The mainspring 15 is located inside the inner circumferential surface of the winding body 13 and rotates the winding body 13 in the direction of winding the wire 12. The mainspring 15 is an example of a spring according to the present invention. The outer end 1311 of the mainspring 15 is fixed to the inner circumferential surface of the winding body 13 and applies a rotational force to the winding body 13 in one direction (in this embodiment, in the direction of arrow A). The load-applying unit 14 applies a load to the unwinding unit 121 by biasing the winding body 13 and the mainspring 15 in the direction of winding the wire 12.

[0048] As shown in Figure 1, an adjustment dial 11 is installed on the main body 10. The adjustment dial 11 is a dial for adjusting the torque of the mainspring 15. The adjustment dial 11 has a central shaft 131 that passes through the rotation center of the winding body 13. The inner end 1312 of the mainspring 15 is fixed to the central shaft 131. For example, when the adjustment dial 11 is rotated in the direction of arrow A in Figure 3, the torque of the mainspring 15 increases, and the load on the pull-out section 121 increases. When the adjustment dial 11 is rotated in the direction of arrow B in Figure 3, the torque of the mainspring 15 decreases, and the load on the pull-out section 121 decreases.

[0049] [Angle adjustment section 20] The angle adjustment unit 20 is located below the main body 10 and is integrally connected to the main body 10. As shown in Figure 1, it is provided so that the mounting angle of the main body 10 can be arbitrarily changed so that the main body 10 rotates upward from a horizontal position relative to the fixed member 8 to a position aligned with the vertical direction. The main body 10 is integrally attached to the top plate portion 222 of the rotating plate 22. Figure 1 shows a case in which a disc-shaped main body 10 having a predetermined thickness is connected to the upper surface of the rotating plate 22, which is roughly pentagonal in plan view, by a plurality of screws 223a, 223b, etc. The rotating plate 22 is installed on the fixed member 8 via a base 38. A pair of left and right support parts 23 are erected on the base 38 at a predetermined distance apart. A rotating shaft 221, which is the rotation center of the rotating plate 22, is mounted on the pair of support parts 23. The rotating plate 22, which has a pair of left and right side plates 224 installed opposite to a support portion 23 erected on a base 38, is supported by a rotation shaft 221 mounted on the support portion 23 so as to be able to rotate freely from a horizontal position to a vertical position. The rotating plate 22 has a roughly fan shape when viewed from the side with respect to the rotation shaft 221, and an arc-shaped elongated hole 24 is formed near the lower outer circumference. The threaded portion of a thumb screw 21 is inserted through the elongated hole 24. The threaded portion of the thumb screw 21 is inserted through the elongated hole 24 of the side plate 224 of the rotating plate 22 and screwed into a threaded hole formed in the support portion 23. When this thumb screw 21 is loosened, the rotating plate 22 is guided by the threaded portion of the thumb screw 21 inserted through the elongated hole 24 and rotates between a horizontal position and a vertical position around the rotation shaft 221. The configuration of the rotating plate 22 with the elongated hole 24, the support portion 23 with screw holes, and the thumb screw 21 is also provided on the rotating plate located on the upper right side of the top plate portion 222 in Figure 1, opposite the rotating plate 22 located on the lower left side of the top plate portion 222 in Figure 1. Since the configuration is the same, the explanation will be omitted. The main body 10, which is integrally attached to the top plate portion 222 of the rotating plate 22, rotates vertically together with the rotating plate 22. In the first embodiment, the angle adjustment portion 20 allows the mounting angle of the main body 10 to be arbitrarily changed by rotating the main body 10 vertically, but it is not limited to this, and may be configured to be rotatable in the vertical and / or horizontal directions, similar to the second embodiment described later.

[0050] Furthermore, the configuration of the rotating plate 22 with the elongated hole 24, the support portion 23 with screw holes, and the thumb screw 21 may be arranged so as to be located only on one side of the top plate portion 222 in Figure 1.

[0051] During training, when the thumb screws 21 located on both sides of the top plate 222 are loosened and the wire 12 is pulled out from the main body 10 by gripping the pull-out section 121, the angle adjustment section 20 is configured to adjust the angle of the main body 10 in accordance with the movement of the wire 12 being pulled out from the main body 10. As a setting, when the thumb screws 21 on both sides are tightened while maintaining that angle, the device is set to maintain a predetermined angle that follows the movement of pulling the wire 12 out from the main body 10.

[0052] According to this, the user can adjust the angle of the main unit 10 according to the type of training, thus expanding the range of training. Furthermore, since the angle adjustment unit 20 is equipped with a setting unit for setting the main unit 10 to maintain a predetermined angle relative to the fixed member, the main unit 10 becomes stable and training can be performed appropriately by fixing the angle of the main unit 10 according to the type of training.

[0053] [Fixed part 30] The fixing part 30 is located below the angle adjustment part 20 and is integrally connected to the angle adjustment part 20. It provides fixing means for fixing the entire device, including the main body 10 and the angle adjustment part 20, to the fixed member 8. In the first embodiment of the present invention, the fixing means includes two suction cups 36a and 36b that fix the main body 10 to the fixed member 8 by negative pressure. The number of suction cups may be one or more.

[0054] According to this, the fixing part 30 is equipped with suction cups 36a and 36b that fix the main body to the fixed member 8 by negative pressure, so it can be easily attached to a flat surface and the training device 1 can be used in a stable attached state.

[0055] The two suction cups 36a and 36b are attached to the underside of the base 38. Each suction cup 36a and 36b has an adsorption part that contacts the fixed member 8 and adheres to it by creating a nearly vacuum airtight seal between them. The base 38 is also equipped with rubber feet 37 to maintain a horizontal position when the base 38 is installed, in relation to the two suction cups 36a and 36b. The fixing part 30 includes a release part 34 for releasing the adsorption of the two adsorbed suction cups 36a and 36b. The release part 34 includes a single release part 342 for releasing the adsorption force of both suction cups 36a and 36b at once. The simultaneous release unit 342 is equipped with a claw portion 343 at the tip of the release lever 341. By sliding the release lever 341, the tip of the claw portion 343 interferes simultaneously with the suction portions of the two suction cups 36a and 36b, thereby opening the suction portions to the outside air, releasing the airtight seal, and simultaneously releasing the suction state.

[0056] According to this, the device is equipped with a release unit 34 that releases the suction force of the suction cups 36a and 36b, and the release unit 34 is equipped with a simultaneous release unit 342 that releases the suction force of multiple suction cups at once, so the main body 10 can be easily attached and detached.

[0057] More specifically, Figure 4 is an enlarged perspective view of the release unit 34. As shown in Figure 4, the release unit 34 has a knob 344 attached to one end of the release lever 341 as an operating part, and a claw part 343 at the other end as a single release unit 342. The release lever 341 is assembled to slide back and forth through an elongated hole 345 formed in the base 38 so as to interfere with the suction cups 36a and 36b, as shown in Figures 1 and 2.

[0058] The fixing part 30 further includes pressing levers 31a and 31b, which rotate and press the upper parts 33a and 33b of the suction cups 36a and 36b installed on the lower part of the base 38, respectively, to adhere to the fixed member 8 and maintain the suction state. The auxiliary levers 32a and 32b are levers that provide an auxiliary grip to make it easier to operate the pressing levers 31a and 31b.

[0059] [Training movements] Training device 1 is used, for example, for muscle training. A user performing muscle training operates the fixing part 30 to fix the entire device, including the main body 10 and the angle adjustment part 20, to the fixed member 8, and repeatedly performs an exercise of pulling out the wire 12 from the case 101 against the load and then returning it by gripping the handle 17.

[0060] Next, a second embodiment of the present invention will be described with reference to Figures 5 and 6.

[0061] [Overall configuration of training device 1] Figure 5 is a perspective view of a training device 1 according to a second embodiment of the present invention. Figure 6 is a longitudinal cross-sectional view showing the structure of the fixing part 30.

[0062] The training device 1 consists of a main body 10, an angle adjustment unit 20, and a fixing unit 30.

[0063] The main body 10 houses a wire 12 as a string-like member inside and is capable of automatically winding up the wire 12 when it is pulled out from the inside. The main body 10 comprises the wire 12, a pull-out section 121 provided at one end of the wire 12 for pulling the wire 12 out of the main body 10, a winding section 141 provided at the other end of the wire 12 for winding the wire 12 into the main body 10, and a load-applying section 14 that applies a load to the pull-out section 121 during the operation of pulling the wire 12 out of the main body 10. (See Figure 3)

[0064] The angle adjustment unit 20 is located below the main body 10 and is integrally connected to the main body 10. It is provided so that the mounting angle of the main body 10 can be arbitrarily changed by rotating the main body 10 in the vertical and / or horizontal directions.

[0065] The fixing part 30 is located below the angle adjustment part 20 and is integrally connected to the angle adjustment part 20. It provides fixing means for fixing the entire device, including the main body 10 and the angle adjustment part 20, to the fixed member 8. In one embodiment of the present invention, the fixing means is composed of a vise mechanism 50 as a clamping part that holds the fixed member 8. The fixed member 8 is the object to which the entire device, including the main body 10 and the angle adjustment part 20, is fixed by the fixing part 30. For example, it is an object arbitrarily selected by the user from flooring, desks, tables, beds, etc. In Figure 6, the fixed member 8 is shown as a part of a desk as an example. For example, a part of a desk is the tabletop or the legs of a desk.

[0066] According to this, the fixing part 30 is equipped with a clamping part that holds the member to be fixed 8, so it can be easily attached and the training device 1 can be used in a stable attached state.

[0067] The three mechanical parts of the training device 1 in the second embodiment will be described in detail. Here, only the parts that differ from the first embodiment will be described, and other parts will be omitted from the description by using the same reference numerals.

[0068] [Main unit 10] Since the main body 10 has the same configuration as the first embodiment, a detailed explanation will be omitted here.

[0069] [Angle adjustment section 20] The angle adjustment unit 20 is located below the main body 10 and is integrally connected to the main body 10. It is provided so that the mounting angle of the main body 10 can be arbitrarily changed by rotating the main body 10 in the vertical and / or horizontal directions. The configuration for rotating the main body 10 vertically is common to both this embodiment and the first embodiment of the angle adjustment unit 20, so only the different configurations will be described here.

[0070] In this embodiment, the configuration for rotating the main body 10 horizontally differs from that of the first embodiment. Below the base frame 58, which corresponds to the pedestal 38 of the first embodiment, the clamping frame 55 is provided opposite the base frame 58 and is supported by a rotation axis 581 so as to be able to rotate horizontally. The base frame 58 has an arc-shaped elongated hole 583 formed in its bottom plate portion 584. The base frame 58 and the clamping frame 55 are fixed through the elongated hole 583 by a thumb screw 582. The thumb screw 582 is fixed through the elongated hole 583 of the base frame 58 to the screw hole of the clamping frame 55. When this thumb screw 582 is loosened, the base frame 58 can rotate horizontally around the rotation axis 581 by the length of the elongated hole 583, and in this embodiment, it can rotate within a range of 90 degrees. The main body 10, which is integrally attached to the top plate portion 222 of the rotating plate 22, rotates vertically and / or horizontally together with the rotating plate 22 and the base frame 58.

[0071] [Fixed part 30] The fixing part 30 is located below the angle adjustment part 20 and is integrally connected to the angle adjustment part 20, and includes fixing means for fixing the entire device, including the main body 10 and the angle adjustment part 20, to the member to be fixed 8. In the second embodiment of the present invention, the fixing means includes a clamping part for clamping the member to be fixed 8.

[0072] As shown in Figure 6, the vise mechanism 50, which acts as a clamping part, moves the movable vise 52 by rotating a knob 536 fixed to the screw 53, and the member to be fixed 8 is held between the movable vise 52 and a fixed vise 51 fixed in a position opposite to it.

[0073] Specifically, the vise mechanism 50 has a clamping frame 55 to which a slide bar 54 supporting a fixed vise 51 and a movable vise 52 is attached. The fixed vise 51 is fixedly installed at the left end of the slide bar 54, fitted into the slide bar 54. The movable vise 52 is fitted into the slide bar 54 so as to be slidable in the left-right direction, opposite the fixed vise 51. Below the slide bar 54, a screw holder 531 is installed, fixed to the clamping frame 55, to hold a screw 53 with threads on its outer circumference for sliding the movable vise 52, and having an internal thread. The movable vise 52 and one end of the screw 53 are connected by inserting a bolt 532 into a recess 537 via a disc spring 534, a resin spacer 535, and a washer 533. A knob 536 for rotating the screw 53 is engaged with the other end of the screw 53.

[0074] In another embodiment, the movable vise 52 is constructed of a resin material with good sliding properties, such as polyacetal, and the upper surface 521 of the movable vise 52 is extended upward to a dimension that allows it to slide against the inner surface 551 of the clamping frame 55. In this case, the upper surface 521 of the movable vise 52 can slide in the left-right direction while in contact with the inner surface 551 of the clamping frame 55. Therefore, the movable vise 52 can slide without play even if the slide bar 54 is structurally omitted.

[0075] In addition, in Figure 6, to improve the clarity of the diagram, the hatching that should be applied to the cross-sections of the movable vise 52, screw 53, disc spring 534, spacer 535, washer 533, bolt 532, screw holder 531, fixed vise 51, knob 536, and clamping frame 55 has been omitted.

[0076] Based on the above, users can easily perform training. Furthermore, the angle of the main unit 10 can be adjusted according to the type of training, expanding the range of training options. In addition, since the fixing means consists of a suction cup that fixes the main unit to the fixed member by negative pressure or a clamping part that grips the fixed member, the training device 1 can be used in a stable mounting state in various locations, and setup is easy.

[0077] Next, a third embodiment of the present invention will be described with reference to Figure 7.

[0078] [Overall configuration of training device 1] Figure 7 is a perspective view of the training device 1 according to a third embodiment of the present invention.

[0079] The training device 1 according to the third embodiment consists of a mounting body 56 equipped with a suction cup 561 for fixing, in addition to the basic configuration of the main body 10, angle adjustment unit 20, and fixing unit 30 of the second embodiment described above. In this embodiment, the mounting body 56 is formed to be detachably attached to the clamping unit. As shown in Figure 7, the mounting body 56 is attached to the clamping unit by rotating the knob 536 in the vise mechanism 50, which serves as the clamping unit, and holding the mounting body 56 between the fixed vise 51 and the movable vise 52. At this time, the entire device can be fixed to the fixed member 8 by the suction cup 561 of the mounting body 56 attached to the clamping unit. When fixing the entire device to the fixed member 8 with the vise mechanism 50, the mounting body 56 can be removed from the vise mechanism 50 before use. When the mounting body 56 is attached to the clamping part, the upper part of the mounting body 56 is positioned between the fixed vise 51 and the movable vise 52 and is housed in the vise mechanism 50 (storage arrangement). Compared to the state in which the clamping part and the mounting body 56 are separated, the overall volume of the fixing means can be made more compact. Therefore, when storing the training device 1, the fixing means can be stored compactly by attaching the mounting body 56 to the clamping part. By configuring the mounting body 56 to be detachable from the clamping part, the options for fixing the main body to the fixed member are expanded, and the fixing means can be stored compactly, which is convenient for the user. Furthermore, if the product is shipped in the aforementioned integrated storage arrangement state, it can be compactly packaged. The fixed member 8 is the object to which the entire device, including the main body 10 and the angle adjustment part 20, is fixed by the fixing part 30, and refers to an object arbitrarily selected by the user from, for example, flooring, desks, tables, beds, etc.

[0080] According to this, the options for fixing the main unit to the fixed member are expanded, and the fixing means can be stored compactly, which is convenient for the user.

[0081] Next, a fourth embodiment of the present invention will be described with reference to Figure 8.

[0082] [Overall configuration of training device 1] Figure 8 is a perspective view of the training device 1 according to the fourth embodiment of the present invention.

[0083] As shown in Figure 8, the training device 1 according to the fourth embodiment consists of a main body 10 and a fixing part 30, and does not have an angle adjustment part 20 like the first embodiment. Therefore, the angle of the main body 10 is adjusted by the mounting location and mounting direction of the fixing part 30 to the member to be fixed.

[0084] The main body 10 houses a wire 12 as a string-like member inside and is capable of automatically winding up the wire 12 when it is pulled out from the inside. The main body 10 comprises the wire 12, a pull-out section 121 provided at one end of the wire 12 for pulling the wire 12 out of the main body 10, a winding section 141 provided at the other end of the wire 12 for winding the wire 12 into the main body 10, and a load-applying section 14 that applies a load to the pull-out section 121 during the operation of pulling the wire 12 out of the main body 10. (See Figure 3)

[0085] The fixing part 30 is located below the main body 10 and is integrally connected to the main body 10. It is equipped with fixing means for fixing the entire device, including the main body 10, to the fixed member 8. In one embodiment of the present invention, the fixing means includes suction cups 36a and 36b that fix the main body 10 to the fixed member 8 by negative pressure. (See Figure 2) The fixed member 8 is an object to which the entire device, including the main body 10 and the angle adjustment part 20, is fixed by the fixing part 30. For example, it can be an object arbitrarily selected by the user from flooring, desks, tables, beds, etc.

[0086] According to this, users can easily perform training. Furthermore, the device can be easily configured and the training device 1 can be used in a stable mounting state in various locations.

[0087] Since the main body 10 and the fixing part 30 have the same configuration as the first embodiment in the fourth embodiment, further detailed explanation is omitted here. Components common to both the first and fourth embodiments are denoted by the same reference numerals.

[0088] Next, a fifth embodiment of the present invention will be described with reference to Figure 9.

[0089] [Overall configuration of training device 1] Figure 9 is a perspective view of the training device 1 according to the fifth embodiment of the present invention.

[0090] As shown in Figure 9, the training device 1 according to the fifth embodiment consists of a main body 10 and a fixing part 30, and does not have an angle adjustment part 20 like the second embodiment. Therefore, the angle of the main body 10 is adjusted by the mounting location and mounting direction of the fixing part 30 to the fixed member 8.

[0091] The main body 10 houses a wire 12 as a string-like member inside and is capable of automatically winding up the wire 12 when it is pulled out from the inside. The main body 10 comprises the wire 12, a pull-out section 121 provided at one end of the wire 12 for pulling the wire 12 out of the main body 10, a winding section 141 provided at the other end of the wire 12 for winding the wire 12 into the main body 10, and a load-applying section 14 that applies a load to the pull-out section 121 during the operation of pulling the wire 12 out of the main body 10. (See Figure 3)

[0092] The fixing part 30 is located below the main body 10 and is integrally connected to the main body 10. It is equipped with fixing means for fixing the entire device, including the main body 10, to the fixed part 8. In one embodiment of the present invention, the fixing means is composed of a vise mechanism 50 as a clamping part that holds the fixed member 8. (See Figure 5) The fixed member 8 is the object to which the entire device, including the main body 10 and the angle adjustment part 20, is fixed by the fixing part 30, and can be flooring, a desk, a table, a bed, etc., arbitrarily selected by the user.

[0093] According to this, users can easily perform training. Furthermore, the device can be easily configured and the training device 1 can be used in a stable mounting state in various locations.

[0094] Since the main body 10 and the fixing part 30 have the same configuration as the second embodiment, further detailed explanation is omitted here. Components common to both the second embodiment and the fifth embodiment are denoted by the same reference numerals.

[0095] Figure 10 is a side view showing the structure of the fixing part 30 of the training device 1 according to the sixth embodiment of the present invention. In this embodiment, the screw holder 531 holds only the lower part of the screw 53. The upper part of the screw 53 is held by the holding lever 57. The holding lever 57 comprises a lever body 570, a handle 571, a female screw portion 574, a swing support portion 573, and a swing shaft 572. In Figure 10, when the lever body 570 is screwed onto the screw 53, as shown by the solid line, the handle 571 is provided on the upper right and the female screw portion 574 is provided on the lower left.

[0096] The swing support portion 573 is located below the handle 571, to the lower right of the lever body 570. The swing support portion 573 is positioned opposite to the left and right sides of the projection 552 that protrudes from the right side of the clamping frame 55 in Figure 10. The swing shaft 572 is installed passing through the pair of left and right swing support portions 573 and the projection 552. The lever body 570 is swingable around the axis of the swing shaft 572, as shown by the dashed line in Figure 10.

[0097] The screw holder 531 and the female threaded portion 574 allow the movable vise 52 to move linearly toward the fixed vise 51 without rotating the screw 53 with the knob 536, while the screw 53 remains screwed in. Conversely, the movable vise 52 cannot be moved linearly toward the fixed vise 51. To move the movable vise 52 toward the fixed vise 51, the screw holder 531 and the female threaded portion 574 are screwed into the screw 53, and the screw 53 is rotated with the knob 536 or the screw is released with the holding lever 57.

[0098] To release the screw 53 from the screw holder 531 and the female thread portion 574 using the holding lever 57, push the handle 571 downwards. The lever body 570 rotates clockwise around the pivot axis 572 as shown by the dashed line in Figure 10, and the female thread portion 574 moves upward away from the screw 53. By moving the knob 536 to the right in Figure 10, the screw 53 can be moved laterally without having to rotate it. This releases the clamped state of the fixed member 8 between the movable vise 52 and the fixed vise 51.

[0099] It should be noted that the present invention is not limited to this embodiment, and within the scope of the technical concept of the present invention, this embodiment can be modified as appropriate in ways other than those suggested here. Furthermore, the number, position, shape, etc. of the constituent members are not limited to this embodiment, and can be set to a number, position, shape, etc. that is suitable for carrying out the present invention.
