Description

Controller and weight training device

[0001] The present invention relates to a controller and a weight training device.

[0002] When training with a weight training device that requires the use of both arms, the user cannot use their hands and therefore cannot operate external devices such as the weight training device with a controller that is operated by hand.

[0003] Patent Document 1 discloses a weight training device that includes a weight with a built-in electromagnet and a conduction relay that controls the supply of power to the electromagnet. This weight training device also includes a sound sensor or other sound-related sensor as a controller.

[0004] In the weight training device described in Patent Document 1, for example, when a user speaks because they cannot withstand the load, a sound sensor detects the voice and sends a signal to the weight training device, and upon receiving the signal, a conductive relay cuts off the supply of power to the weight containing the electromagnet, causing the weight that has been attracted to the weight containing the electromagnet to detach (fall off).

[0005] Japanese Patent Application Laid-Open No. 2020-179166

[0006] However, if a sound sensor is used as a controller, factors such as noise and volume may prevent the weight attached to the weight incorporating the electromagnet from being released when desired, or it may release when not desired, making it impossible to properly control the release of the attached weight.

[0007] An object of the present invention is to provide a controller that allows an user to appropriately operate an external device without using his or her hands, and a weight training device that includes the controller.

[0008] The controller includes a mounting part that can be worn on the user's head, two chin hooks that are attached to the mounting part with a gap between them and can be hung on the user's lower jaw, a transmitter that can transmit signals to an external device, and a control part. The chin hooks are movable or extendable relative to the mounting part when the user opens their mouth. The control part can measure or detect the displacement of the chin hook relative to the mounting part, and when the displacement of the chin hook exceeds a predetermined amount, it causes the transmitter to transmit a signal.

[0009] The controller may have a pair of winding units in the mounting section, each of which has a rotatable reel, and each reel is attached to one side or the other of the chin rest, and can wind up and unwind the chin rest by rotating.

[0010] The winding portion may include an elastic body, which exerts a restoring force (biases) the reel so that the reel rotates in the direction of winding the chin hook.

[0011] The reel of at least one of the winding units may include a magnetic body, and the control unit may include a magnetic switch on the winding unit where the reel includes the magnetic body. The magnetic body approaches or moves away from the magnetic switch as the reel rotates. When the magnetic body approaches, the magnetic switch turns on and causes the transmitter to output a signal.

[0012] The winding section, in which the reel is provided with a magnetic material, may be provided with a rotatable position adjustment section. The magnetic switch is provided in the position adjustment section, and can be moved toward or away from the magnetic material by rotating the position adjustment section.

[0013] The controller may include a light emitting unit that emits light visible to a user wearing the controller, and the control unit causes the light emitting unit to emit light when the displacement of the chin rest is equal to or greater than a predetermined amount.

[0014] The reel of at least one of the winding units may include a magnetic body, and the winding unit having the magnetic body may include a light-emitting unit that emits light visible to the user, and the control unit may include a magnetic switch on the winding unit having the magnetic body. The magnetic body approaches or moves away from the magnetic switch as the reel rotates. When the magnetic body approaches, the magnetic switch turns on, causing the light-emitting unit to emit light.

[0015] The weight training device includes the controller, a transmission unit that transmits the load of the weight in response to user operation, an electromagnet unit that is provided in the transmission unit and includes an electromagnet, an attractive weight that can be attracted to the electromagnet unit by the magnetic force of the electromagnet, a receiving unit that can receive signals from the transmitting unit, and a device control unit. The device control unit controls the supply of electricity to the electromagnet based on whether or not the receiving unit receives a signal, and controls the attraction and detachment of the attractive weight from the electromagnet unit.

[0016] The controller allows the user to appropriately operate external devices without using their hands, and the weight training device allows the user to appropriately release the adhesive weight by operating the controller.

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A controller 1 includes a mounting unit 10, a chin strap unit 40, a transmitter unit 50, a light emitter unit 60, and a controller unit .

[0019] In this embodiment, the mounting portion 10 includes a mounting portion main body 20 and a pair of winding portions 30, as shown in FIGS.

[0020] The wearing portion main body 20 can be worn on the head of the user U. The wearing portion main body 20 is preferably worn on the head of the user U above the mouth. In this embodiment, as shown in FIGS. 1 to 3 , the wearing portion main body 20 is eyeglass-shaped and includes a frame 21, a pair of temples 23 provided on the left and right sides of the frame 21, lenses 25 provided on the frame 21, and a pad 27 provided on the frame 21 and placed on the nose of the user U. The wearing portion main body 20 may be other than the eyeglass-shaped one described above, as long as it can be worn on the head of the user U. For example, the wearing portion main body 20 may be a band or the like that is wrapped around the head.

[0021] The winding section 30 is for winding up the chin hook 40, which will be described later. In this embodiment, the winding section 30 is provided on each of the left and right sides of the attachment main body 20. As shown in FIGS. 1 to 9 , the winding section 30 includes a cover 31, an attachment section 32, a first shaft section 33, a second shaft section 34, a reel 35, an elastic body 36, and a position adjustment section 37.

[0022] The cover 31 has an internal space in which the components of the winding unit 30 are housed. As shown in FIGS. 1 to 3 , each cover 31 is connected to the left and right sides of the frame 21 of the mounting unit main body 20 via attachment parts 32 so as to be positioned outward in the left-right direction from the mounting unit main body 20. The cover 31 has an access part 31a extending downward from its front surface. The access part 31a is cylindrical, and its interior communicates with the inside and outside of the cover 31. The cover 31 also has an elongated hole 31b extending from its front surface to its bottom surface.

[0023] As shown in Figures 4 to 9, a first shaft 33 and a second shaft 34 are provided inside the cover 31 and are directly or indirectly connected to the cover 31. The first shaft 33 is provided integrally with the cover 31. The first shaft 33 has a shape with a portion cut out of a cylinder, and its axis is approximately parallel to the left-right direction. The second shaft 34 is cylindrical and connected to the first shaft 33. The second shaft 34 is provided outward in the left-right direction from the first shaft 33. The axis of the second shaft 34 is approximately parallel to the left-right direction and is the same axis as the first shaft 33.

[0024] 4 to 6, the first shaft portion 33 is provided with a recess 33a recessed from the tip end surface toward the rear in the axial direction. The tip end surface of the first shaft portion 33 is also provided with a first shaft portion groove 33b that is connected to the recess 33a and extends linearly from the recess 33a toward the outside in the radial direction of the first shaft portion 33.

[0025] As shown in FIGS. 4 to 6 , the reel 35 is rotatably mounted on the first shaft portion 33. The reel 35 is annular, with the first shaft portion 33 passing through a hole in the reel 35 and rotatable around the first shaft portion 33. An annular outer circumferential groove 35a is provided on the outer periphery of the reel 35. Furthermore, a reel groove 35b is provided on the distal end surface of the first shaft portion 33 and on the surface facing the position adjustment portion of the reel 35. The reel groove 35b connects to the recess 33a and extends linearly from the recess 33a toward the radially outer side of the first shaft portion 33 to the reel 35. The reel groove 35b extends in a different direction from the first shaft groove 33b. Furthermore, a cylindrical magnetic body mounting portion 35c is provided on the surface of the reel 35 facing the position adjustment portion at a predetermined distance from the center of the reel 35. A magnetic body 35d is fitted into the magnetic body mounting portion 35c. The magnetic body 35d is a cylindrical or disk-shaped magnet.

[0026] As shown in Figures 4 to 6, the reel 35 and the first shaft portion 33 are provided with an elastic body 36. In this embodiment, the elastic body 36 is a torsion spring. The elastic body 36 has an inner diameter portion 36a that is fitted in the recess 33a, one arm portion 36b that is fitted in the first shaft portion groove 33b, and the other arm portion 36b that is fitted in the reel groove 35b. A screw is passed through the inner diameter portion 36a of the elastic body 36, and the elastic body 36 is attached to the first shaft portion 33 with the screw.

[0027] As shown in Figures 4 and 7 to 9, a position adjustment unit 37 is rotatably provided on the second shaft unit 34. The position adjustment unit 37 is annular, with the second shaft unit 34 passing through a hole in the position adjustment unit 37, allowing the position adjustment unit 37 to rotate around the second shaft unit 34. An inwardly recessed switch housing unit 37a is provided on the surface of the position adjustment unit 37 facing the reel 35. The distance from the center of the position adjustment unit to the switch housing unit 37a is approximately the same as the distance from the center of the reel 35 to the magnetic body 35d. The position adjustment unit 37 is provided with a lever 37b that passes through the elongated hole 31b from its outer circumferential surface and protrudes outward.

[0028] The chin rests 40 are attached to the attachment unit 10 at intervals so that they can be placed around the lower chin of the user U. The chin rests 40 can move or extend relative to the attachment unit 10 when the user U opens their mouth (when an external force is applied).

[0029] In this embodiment, as shown in Figures 1 to 3, the chin hook 40 includes a chin hook main body 41 and a chin rest 43. The chin hook main body 41 is flexible and linear. In this embodiment, the chin hook main body 41 is a fiber string. Each end of the chin hook main body 41 is attached to the outer circumferential groove 35a of the reel 35 of each winding unit 30.

[0030] The chin rest 43 is a portion that comes into contact with the lower jaw of the user U, and has a bowl-like shape that can accommodate the lower jaw of the user U. A plurality of holes (not shown) are formed in the chin rest 43. The chin rest 43 is attached to the chin rest main body 41 by passing the chin rest 43 through the plurality of holes in the chin rest 43 so that the chin rest 43 passes through the inside and outside of the chin rest 43.

[0031] The chin rest main body 41 may be a member that extends relative to the attachment part 10, and may be, for example, a rubber or spring attached to the attachment main body. In this case, the winding part 30 is not necessary.

[0032] 1, 2, and 5, in the initial state where no external force is acting on the chin hook 40, the chin hook main body 41 of the chin hook 40 is wound around the reel 35 of the winding unit 30, and the chin hook 40 is located in its initial position. When an external force that attempts to lower the chin hook 40 acts on the chin hook 40, the reel 35 of the winding unit 30 rotates in a direction (one side) that feeds the chin hook main body 41 from the winding unit 30, and the chin hook 40 is fed from the winding unit 30 and lowers. At this time, due to deformation of the elastic body 36, a restoring force of the elastic body 36 acts on the reel 35 to rotate the reel 35 in a direction that winds up the chin hook main body 41. When the external force tending to lower the chin hook portion 40 is removed, the restoring force of the elastic body 36 causes the reel 35 of the winding portion 30 to rotate in the direction of winding the chin hook portion main body 41 (the other side), the chin hook portion main body 41 is wound onto the reel 35, and the chin hook portion 40 returns to its initial position.

[0033] The elastic body 36 may be any elastic body 36 such as a coil spring, as long as the restoring force as described above acts on the reel 35 .

[0034] The transmitter 50 is for transmitting signals to an external device. In this embodiment, the transmitter 50 is provided inside the case of the retractor 30, as shown in Figures 5 to 9. The external device may be any type, and examples include weight training equipment, game machines, and medical equipment.

[0035] The light-emitting unit 60 emits light visible to the user U. In this embodiment, the light-emitting unit 60 is an LED light, and is provided on the front side of the case of the right-side transmitter 50, as shown in FIG. 1. The light-emitting unit 60 is connected to the transmitter 50 by a wiring 61, as shown in FIGS. 5 and 6. The light-emitting unit 60 is capable of emitting light forward.

[0036] The control unit 70 is capable of measuring or detecting the displacement of the chin rest 40 relative to the wearing unit 10, and controls the transmission of the transmitting unit 50 and the emission of the light emitting unit 60 based on the measurement or detection.

[0037] In this embodiment, the control unit 70 is a magnetic switch. As shown in FIG. 4 , the control unit 70 is attached to the switch housing 37a of the position adjustment unit. The control unit 70 is connected to the transmitter 50 by a wire 71. The control unit 70 is also connected to the light-emitting unit 60 via the transmitter 50. The control unit 70 is also connected to a battery (not shown), which serves as a power source. The control unit 70 is turned on when the magnetic body 35d approaches and turned off when the magnetic body 35d moves away from the magnetic body 35d. When the control unit 70 is turned on, it supplies power to the transmitter 50 and the light-emitting unit 60. Upon receiving the power supply, the transmitter 50 transmits a signal to an external device, and the light-emitting unit 60 emits light. When the control unit 70 is turned off, it does not supply power to the transmitter 50 and the light-emitting unit 60. In response to this, the transmitter 50 does not transmit a signal to the external device, and the light-emitting unit 60 does not emit light.

[0038] As shown in Fig. 8, in the initial state, the magnetic body 35d is separated from the control unit 70 (magnetic switch), and the control unit 70 is turned off. As shown in Fig. 9, when the reel 35 rotates in the direction in which the chin hook main body 41 is unwound, the magnetic body 35d approaches the control unit 70. Furthermore, when the reel 35 rotates in the direction in which the chin hook main body 41 is wound up, the magnetic body 35d moves away from the magnetic switch. When the chin hook main body 41 is unwound by a predetermined amount from the winding unit 30, in other words, when the displacement of the chin hook 40 relative to the attachment unit 10 exceeds a predetermined amount, the magnetic body 35d approaches the control unit 70, and the control unit 70 is turned on, causing the transmitter 50 to transmit a signal to an external device and the light-emitting unit 60 to emit light.

[0039] 7 and 8, the position of the control unit 70 in the initial state can be adjusted by operating the lever 37b of the position adjustment unit 37 to rotate the position adjustment unit 37. By adjusting the position of the control unit 70, the amount of displacement of the chin rest 40 at which the control unit 70 is turned on can be adjusted.

[0040] Note that the control unit 70 may be any device that can measure or detect the displacement of the chin hook 40 relative to the attachment unit 10 and that can control the transmission of the transmission unit 50 and the emission of the light-emitting unit 60 based on the measurement or detection. For example, the control unit 70 may include a displacement meter that measures the displacement of the chin hook 40 and a control device that includes a CPU and memory, and the control device may cause the transmission unit 50 to transmit a signal and the light-emitting unit 60 to emit light based on the measurement of the displacement meter.

[0041] As shown in Figures 10 and 11 , the above-described controller 1 is used by wearing the attachment unit 10 on the head of the user U like eyeglasses, and by fitting the chin rest 43 around the user U's lower jaw and hanging the chin hook unit 40 around the user U's lower jaw. As shown in Figure 10 , when the user U has their mouth closed, the control unit 70 of the controller 1 is off, the transmitter 50 does not transmit a signal, and the light-emitting unit 60 does not emit light. As shown in Figure 11 , when the user U opens their mouth, the chin hook main body 41 is unwound from the winding unit 30, following the user U's lower jaw, and the magnetic body 35d approaches the control unit 70 due to the rotation of the reel 35. When the magnetic body 35d approaches the control unit 70, the control unit 70 is turned on, a signal is transmitted from the transmitter 50, and the light-emitting unit 60 emits light. As the opening of the user U's mouth closes, the chin hook main body 41 is wound up onto the winding section 30, following the user U's lower jaw, and the magnetic body 35d moves away from the control section 70 as the reel 35 rotates, turning off the control section 70, stopping the transmission of signals from the transmitting section 50 and causing the light emitting section 60 to stop emitting light.

[0042] Next, a description will be given of a weight training device equipped with the above-described controller 1. Although the weight training device is not limited to this, a stack-type training device 100 and a free weight-type training device 200 will be described as examples.

[0043] As shown in FIG. 12, the stack-type training device 100 includes the controller 1, a frame 21, a transmission unit 120, a weight 130, stack pins 140, a receiving unit 150, and a device control unit 160.

[0044] Each component of the stack-type training device 100 is attached to the frame 110. The transmission unit 120 transmits the load of the weight 130 to the user U. In this embodiment, the transmission unit 120 includes an operating unit (not shown), a linear body 121, and a weight support unit 123. The operating unit is a portion where the user U operates the weight 130 with their arms or legs. The linear body 121 is made of metal and has one end connected to the operating unit. The linear body 121 is hung on a pulley provided on the frame 110, and the other end is suspended from the frame 110. The weight support unit 123 is pin-shaped, and its rear end (upper end) is connected to the other end of the linear body. The weight support unit 123 has multiple pin holes 125 that penetrate horizontally (front-to-back) at intervals along its longitudinal direction (up-down direction).

[0045] The weight 130 is used to apply a load to the user U. In this embodiment, the weight 130 includes a plurality of electromagnetic weights 131 and a plurality of attractive weights 133. The electromagnetic weight 131 (electromagnet portion) is a substantially rectangular plate-like member and includes an electromagnet in its entirety or in part. The electromagnet may be, for example, an electromagnet or a permanent electromagnet, and an electromagnet is used here. The attractive weight 133 has substantially the same shape as the electromagnetic weight 131 and is capable of being attracted to the electromagnetic weight 131. Here, the attractive weight 133 is made of a non-magnetic weight. The weight 130 is stacked from top to bottom, with the electromagnetic weights 131 and the attractive weights 133 alternately aligned. The electromagnetic weights 131 and the attractive weights 133 are passed through the frame 110 and can be raised and lowered. All of the weights 131, 133 are provided with holes (not shown) for the weight support parts 123 that penetrate in the vertical direction and allow the weight support parts 123 to pass through. The weight support parts 123 pass through the holes for the weight support parts 123. The electromagnetic weight 131 has a pin hole 137 that penetrates in the horizontal direction (front-to-back direction). In a non-operation state where the operating unit is not being operated, the pin hole 137 of the electromagnetic weight 131 overlaps with the pin hole 125 of the weight support part 123.

[0046] The stack pin 140 is used to support the weight 130 on the transmission part 120. As shown in FIG.

[0047] The pin portion 141 is conductive and can be inserted into and removed from the overlapping pin holes 125, 137 of the electromagnetic weight 131 and the weight support portion 123. The handle portion 143 is a handle for inserting and removing the pin portion 141 into and from the pin holes 125, 137, and is connected to the rear end of the pin portion 141.

[0048] The handle 143 is provided with a power supply, a receiving unit 150, and a device control unit 160. The power supply serves as a source of power supply to the receiving unit 150, the device control unit 160, and the electromagnetic weight 131.

[0049] The receiving unit 150 is capable of receiving a signal transmitted by the transmitting unit 50 of the controller 1 .

[0050] The device control unit 160 controls the supply of power to the electromagnetic weight 131 via the pin portion 141 based on the signal received by the receiving unit 150. The device control unit 160 is electrically connected to the transmitting unit 50 and the pin portion 141. In this embodiment, the device control unit 160 is a relay circuit. When the pin portion 141 of the stack pin 140 is inserted into the pin hole 137 of the electromagnetic weight 131 and the receiving unit 150 is not receiving a signal from the transmitting unit 50, the device control unit 160 supplies power via the pin portion 141 to the electromagnetic weight 131 into which the stack pin 140 is inserted, and the electromagnetic weight 131 into which the stack pin 140 is inserted becomes able to attract the attraction weight 133. In addition, when the receiving unit 150 receives a signal from the transmitting unit 50, the device control unit 160 cuts off the supply of power to the electromagnetic weight 131 into which the stack pin 140 is inserted, and the electromagnetic weight 131 into which the pin portion 141 is inserted becomes unable to adsorb the adsorption weight 133.

[0051] Next, we will explain how to use the stack-type training device 100. As shown in Figures 10 and 11, the user U wears the attachment unit 10 of the controller 1 on their head like eyeglasses. They also place the chin hook 40 around their lower chin so that the chin rest 43 of the chin hook 40 is in contact with their lower chin.

[0052] 12 , in the stack-type training device 100, stack pins 140 are inserted into the overlapping pin holes 125, 137 of the corresponding electromagnetic weights 131 and weight support portions 123 so that the user U can receive the desired load. When the stack pins 140 are inserted into the pin holes 125, 137, power is supplied to the electromagnetic weight 131 into which the stack pin 140 is inserted, and the attractive weight 133 directly below it is attracted to the electromagnetic weight 131. The attractive weight 133 is supported by the magnetic force of the electromagnetic weight 131 into which the stack pin 140 is inserted. The load weights that apply a load to the user U are the electromagnetic weight 131 into which the stack pin 140 is inserted, the weights 131, 133 above the electromagnetic weight 131, and the attractive weight 133 attracted directly below the electromagnetic weight 131.

[0053] In the above state, the user U performs training by operating the operating unit to raise and lower the load weight via the transmission unit 120. During training, if the user U's mouth is closed or the opening of the mouth is less than a predetermined amount, no signal is transmitted from the transmission unit 50 of the controller 1, and the suction weight 133 remains attached to the electromagnetic weight 131. If the user U wishes to reduce the load, for example because they cannot bear the load, they can open their mouth more than a predetermined amount, at which point a signal is transmitted from the transmission unit 50 of the controller 1, the receiving unit 150 of the stack-type training device 100 receives the signal, and the device control unit 160 cuts off the supply of power to the electromagnetic weight 131 into which the stack pin 140 is inserted, causing the suction weight 133 to fall or no longer follow the raising and lowering of the load weight, as shown in FIG.

[0054] Next, a description will be given of the free weight type training machine 200. The free weight type training machine 200 comprises the above-mentioned controller 1, a transmission unit 220, weights 230, a collar 240, a receiving unit 250, and a machine control unit 260.

[0055] As shown in FIG. 14 , the transmission unit 220 is a shaft and also corresponds to the operating unit. The weight 230 includes a normal weight 231 and an attractive weight 233. The normal weight 231 is one or more disk-shaped weights, and has a hole in its center for passing the transmission unit 220 (shaft). The attractive weight 233 is a weight that can be attracted to the electromagnet unit 243. The attractive weight 233 is rectangular and made of a non-magnetic material. The normal weights 231 are attached to both sides of the transmission unit 220, and the attractive weights 233 are attached by being attracted to the electromagnet unit 243 of each collar 240.

[0056] The collar 240 is typically used to attach the weight 231 to the transmission unit 220. In this embodiment, as shown in FIGS. 14 and 15 , the collar 240 includes a collar body 241, an electromagnet unit 243, a receiver 250, and a device control unit 260. The collar body 241 is generally rectangular and has a space therein large enough to accommodate the components of the collar 240. The collar body 241 also includes a hole 242 for passing the transmission unit 220 (shaft). The electromagnet unit 243 is provided on the bottom surface of the collar body 241 and includes an electromagnet in its entirety or in part. The electromagnet may be, for example, an electromagnet or a permanent electromagnet; an electromagnet is used here. The power source supplies power to the receiver 250 and the device control unit 260 and is provided within the collar body 241. The receiver 250 is the same as that in the stack-type training device 100 and is provided in the collar body 241. The device control unit 260 controls the supply of power to the electromagnet unit 243 based on whether or not the receiving unit 250 has received a signal. The device control unit 260 is electrically connected to the power source, the transmitting unit 50, and the electromagnet unit 243. In this embodiment, the device control unit 260 is a relay circuit. When the receiving unit 250 has not received a signal from the transmitting unit 50, the device control unit 260 supplies power to the electromagnet unit 243, enabling the electromagnet unit 243 to attract the attraction weight 233. When the receiving unit 250 has received a signal from the transmitting unit 50, the device control unit 260 cuts off the supply of power to the electromagnet unit 243, preventing the electromagnet unit 243 from attracting the attraction weight 233.

[0057] Next, a method of using the free-weight training device 200 using the controller 1 will be described. The user U wears the controller 1 on their head as described above. With regard to the free-weight training device 200, as shown in FIG. 14 , normal weights 231 are attached to both ends of the transmission unit 220 by means of collars 240. In addition, the attraction weights 233 are attracted to the electromagnet units 243 of each collar 240.

[0058] The free-weight training device 200 is used in a similar manner to a typical free-weight training device 200 (barbell). During training, if the user U's mouth is closed or the opening of the mouth is less than a predetermined amount, no signal is transmitted from the transmitter 50 of the controller 1, and the attractive weight 233 remains attracted to the electromagnet unit 243. If the user U wishes to reduce the load, for example because the load is unbearable, the user U opens their mouth by more than a predetermined amount, which transmits a signal from the transmitter 50 of the controller 1. The receiver 250 of the free-weight training device 200 receives the signal, and the device control unit 260 cuts off the supply of power to the electromagnet unit 243, causing the attractive weight 233 to fall, as shown in FIG. 16 .

[0059] The controller 1 allows the user to appropriately operate an external device without using their hands.

[0060] The controller 1 includes a winding section 30, and the chin hook 40 can be wound up on a reel 35, allowing the controller 1 to be made compact when not in use. Furthermore, the length of the chin hook 40 that protrudes from the winding section 30 can be adjusted, allowing the chin hook 40 to fit the lower jaw of any user U.

[0061] The controller 1 is provided with an elastic body 36 on the reel 35, and a restoring force acts on the reel 35 so that the elastic body 36 rotates in the direction in which the chin hook 40 is wound up, thereby applying tension to the chin hook 40 on the lower chin of the user U, thereby enabling the chin hook 40 to reliably follow the movement of the lower chin of the user U and ultimately enabling more accurate operation of external devices. Furthermore, the controller 1 can automatically wind up the chin hook 40 that has been fed out from the winding unit 30 onto the reel 35.

[0062] The controller 1 is provided with the light emitting unit 60, so that the transmitter of the controller 1 transmits a signal to an external device, allowing the user U to check whether the controller 1 is being operated appropriately.

[0063] In the weight training device of the present invention, the user U can appropriately release the adhesive weights 133 and 233 by operating the controller 1.

[0064] The present invention is not particularly limited to the above-described embodiment, and can be modified as appropriate within the scope of the gist of the present invention.
