[0011] A training system 1 according to an embodiment of the present disclosure will be described below with reference to FIGS.
[0012] [Configuration of the Training System] First, the general configuration of the training system 1 will be described with reference to Figures 1 and 2. Figure 1 is a schematic diagram showing the overall configuration of the training system 1. Figure 2 is a block diagram showing the configuration of a load control unit 10 and a display device 20.
[0013] 1, the training system 1 includes a load control unit 10 and a display device 20. The load control unit 10 is a device for applying an additional braking force to the load generated by a weight 141 (described later) of the training device 100.
[0014] Training machine 100 has seat 300 for the user to sit on and handles 301 for the user to grasp with both hands to push open or lift up. Display device 20 is supported by support device 200 attached to training machine 100.
[0015] 2, the load control unit 10 has a control unit 15, a setting unit 16, a storage unit 17, and a communication unit 18. The control unit 15 controls each part of the load control unit 10. The control unit 15 also controls the magnitude of the braking force that is added to the load generated by the weight 141.
[0016] Furthermore, setting unit 16 sets a load waveform that indicates the displacement of the braking force added to weight 141. Storage unit 17 is made up of a semiconductor memory, and stores various data used for controlling load control unit 10. Communication unit 18 is connected to be able to communicate with communication unit 25 of display device 20 via short-range wireless communication such as Bluetooth (registered trademark).
[0017] The display device 20 is, for example, a communication device such as a smartphone or a tablet carried by a user. The display device 20 includes a processing unit 21, a touch panel 22, a display 23, a memory 24, and a communication unit 25.
[0018] The processing unit 21 controls each unit of the display device 20. The touch panel 22 is arranged on the screen of the display 23, detects the position pressed on the screen, accepts input from the user, and outputs it to the processing unit 21. The display 23 is a display screen such as a liquid crystal display or an organic EL (Electro Luminescence) display, and displays images. The memory 24 has a dedicated application stored in advance. The communication unit 25 is connected to the communication unit 18 of the load control unit 10 so as to be able to communicate with it.
[0019] [Configuration of Training Apparatus] Next, the general configuration of the training apparatus 100 will be described with reference to Figures 3 and 4. Figure 3 is a schematic diagram showing the general configuration of the training apparatus 100 in which the load control unit 10 is arranged. Figure 4 is a cross-sectional view of the load control unit 10 taken along line IV-IV as viewed from the left side. For ease of explanation, the up-down direction, left-right direction, and front-rear direction of the training apparatus 100 will be defined below as shown by the arrows in Figures 3 and 4.
[0020] 3 and 4, training device 100 has a weight stack structure in which multiple weights 141 are stacked. Training device 100 is a weight stack type training device in which weights 141 move back and forth in the vertical direction, i.e., up and down, in response to the user's stroke. Here, a stroke refers to the action of the user operating handle 301 to move weights 141 from the lowest position to the highest position.
[0021] The weight 141 is used as a load for the training device 100 via a cable or pulley, allowing for a variety of training depending on the type of training, thereby enabling the user to perform effective muscle training.
[0022] The training device 100 allows a specific weight to be set by stacking multiple weights 141 to form a weight stack 140. The resistance control unit 10 detects the movement of the weight stack 140 in real time. The resistance control unit 10 then applies additional damping force to the weight selected by the user. This allows the user to fine-tune the resistance.
[0023] As shown in FIG. 3, the training device 100 has a right frame 111, an upper frame 112, a left frame 113, a lower frame 114, a cable 120, a pulley 131, a pulley 132, a pulley 133, a pulley 134, a weight stack 140, a lift shaft 151, a left guide shaft 152, and a right guide shaft 153.
[0024] The upper frame 112, the left frame 113, and the lower frame 114 form the framework for supporting the weight stack 140. The right frame 111 and the left frame 113 extend in the vertical direction and are connected by the upper frame 112 and the lower frame 114.
[0025] The cable 120 is used by the user to apply resistance to his or her body for training. One end 121 of the cable 120 is connected to a handle that the user holds with his or her hand. The other end 122 of the cable 120 is fixed to the upper frame 112.
[0026] Each of the pulleys 131 to 134 has a rotatable structure and is arranged to allow smooth movement of the cable 120. The pulley 134 is hung on the cable 120 and connected to the tip of the lift shaft 151. When one end 121 of the cable 120 is pulled, the pulley 134 rises because the other end 122 of the cable 120 is fixed to the upper frame 112. As the pulley 134 rises, the lift shaft 151 also rises.
[0027] The user can select any weight by replacing the pin P, allowing for quick and easy load adjustment. The lift shaft 151 is located in the center of the weight stack 140 and generates training load by raising and lowering it. The left guide shaft 152 and the right guide shaft 153 complement the lift shaft 151 and maintain the overall balance and stability of the weight stack 140.
[0028] The load control unit 10 is placed directly below the weight stack 140. This placement allows the load control unit 10 to detect the movement of the weight stack 140 in real time and make accurate load adjustments. The load control unit 10 can be retrofitted to training equipment already installed in a training facility, allowing for flexible compatibility with existing equipment.
[0029] This makes it easy to upgrade training equipment, allowing users to perform more effective training using the load control unit 10. The load control unit 10 may also be installed in training equipment before it is installed in a training facility, and may also be applied to newly introduced training equipment.
[0030] [Configuration of Load Control Unit] Next, the load control unit 10 will be described in detail with reference to Fig. 4. As shown in Fig. 4, the load control unit 10 includes a reel 11, a cable 12, a rotation detection unit 13, a magnetorheological fluid device 14, and a control unit 15.
[0031] The reel 11 has a rotating shaft member 11a. The cable 12 is connected to the lift shaft 151. The reel 11 is arranged to be rotatable around the rotating shaft member 11a as a rotation axis. The cable 12 is wound around the reel 11.
[0032] When the lift shaft 151 is raised, the cable 12 is unwound from the reel 11. On the other hand, when the lift shaft 151 is lowered, the cable 12 is wound onto the reel 11.
[0033] The rotation detection unit 13 detects the amount and direction of rotation of the rotating shaft member 11a and transmits the detection results to the control unit 15. The rotation detection unit 13 is, for example, a rotary encoder. The rotary encoder detects the rotation angle and rotation speed of the rotating shaft member 11a and transmits the detection results to the control unit 15. The control unit 15 controls the rotation of the reel 11 based on the amount and direction of rotation of the rotating shaft member 11a detected by the rotation detection unit 13.
[0034] Alternatively, a magnetic sensor or an optical sensor may be used as the rotation detector 13. The magnetic sensor detects the movement of a magnet attached to the rotating shaft member 11a and detects the amount and direction of rotation. The magnetic sensor transmits a control signal corresponding to the rotation of the rotating shaft member 11a to the controller 15.
[0035] The magnetorheological fluid device 14 includes a magnetorheological fluid 14 a and a container 14 b. The container 14 b contains the magnetorheological fluid 14 a. The magnetorheological fluid 14 a has a characteristic that its viscosity changes depending on the strength of the applied magnetic field.
[0036] An opening 14c is provided in the front surface of the container 14b. The rear portion 11b of the rotating shaft member 11a is inserted into the container 14b through the opening 14c. The magnetorheological fluid device 14 applies a braking force to the rear portion 11b of the rotating shaft member 11a inserted in the container 14b by changing the viscosity of the magnetorheological fluid 14a.
[0037] Specifically, the magnetorheological fluid device 14 has a rotor to which the rotating shaft member 11a is fixed and a coil that applies a magnetic field to the rotor. A magnetic field is generated when a current flows through the coil. This magnetic field changes the viscosity of the magnetorheological fluid 14a. The change in viscosity of the magnetorheological fluid 14a applies a braking force that prevents rotation of the rotor, i.e., rotation of the rear portion 11b of the rotating shaft member 11a. The prevention of rotation of the rotating shaft member 11a prevents rotation of the reel 11.
[0038] The control unit 15 is a device for comprehensively controlling each component of the load control unit 10. The control unit 15 changes the viscosity of the magnetorheological fluid 14a by adjusting the strength of the magnetic field applied to the magnetorheological fluid 14a. The control unit 15 adjusts the braking force applied to the rear portion 11b of the rotating shaft member 11a to precisely adjust the training load.
[0039] The control unit 15 realizes the training load set by the user by controlling the operation of the magnetorheological fluid device 14 based on the detection result by the rotation detection unit 13. The control unit 15 can adjust the load in real time according to the progress of the training or changes in the load.
[0040] A laser range finder 19 is provided at the front of the load control unit 10. The laser range finder 19 measures the distance to the weight 141 into which the user has inserted a pin P, out of the multiple weights 141 included in the weight stack 140. Based on this measurement result, the control unit 15 calculates the total weight of the weights 141 lifted by the user. This makes it possible to appropriately manage the load during training.
[0041] [Function of Load Control Unit] Next, the function of the load control unit 10 will be described with reference to Figures 3 and 4. When using the training device 100, the user determines the total weight by selecting each weight 141 to be lifted. Then, the user inserts a pin P through the pin insertion hole 141a of the lowest weight 141 of the weights 141 to be lifted and the pin insertion hole 151a of the lift shaft 151.
[0042] When a user grips the handles (not shown) of the training device 100 with both hands and performs a training motion, the lift shaft 151 rises, and the weights 141 selected by the user also rise.
[0043] When the user starts a stroke, the lift shaft 151 rises, and the cable 12 connected to the lower end of the lift shaft 151 also rises. At this time, the cable 12 is pulled out from the reel 11. When the cable 12 is pulled out from the reel 11, the rotary shaft member 11a of the reel 11 rotates.
[0044] The rotation detection unit 13 detects the amount and direction of rotation of the rotating shaft member 11a and transmits the detection result to the control unit 15. Based on the detection result by the rotation detection unit 13, the control unit 15 transmits to the magnetorheological fluid device 14 an instruction to change the strength of the magnetic field applied to the magnetorheological fluid 14a.
[0045] Based on instructions from the control unit 15, the magnetorheological fluid device 14 changes the strength of the magnetic field applied to the magnetorheological fluid 14a, thereby changing the viscosity of the magnetorheological fluid 14a, thereby generating a braking force that prevents rotation of the rear part 11b of the rotating shaft member 11a.
[0046] [Control Flow of Training System] Next, the control flow of the training system 1 will be described with reference to the flowchart in Fig. 5. As shown in Fig. 5, first, the processing unit 21 of the display device 20 determines whether or not the user has operated the touch panel 22 to log in to a dedicated application (S1).
[0047] The processing unit 21 repeats step S1 until a login is made using the application on the display device 20 (S1: NO), and when a login is made by the user (S1: YES), an input screen (not shown) for allowing the user to input training information is displayed on the display 23.
[0048] The user inputs training information by entering the training information into the input screen displayed on the display 23 (S2: input step).
[0049] The training information includes information about the user's age and gender, the type and position of the sport the user wishes to train, and the athlete the user aims to train in. The user inputs information such as age: 30, gender: male, desired sport: baseball, position: pitcher, and target athlete: XX player into the touch panel 22 as the training information.
[0050] After step S2, the processing unit 21 displays on the display 23 a load waveform corresponding to the training information input to the touch panel 22 (S3: display step).
[0051] It is assumed that a plurality of load waveforms corresponding to the content of the training information are stored in the memory unit 17 of the load control unit 10. For example, if the training information input to the touch panel 22 includes a baseball pitcher, it is assumed that a load waveform suitable for training a baseball pitcher is stored in advance in the memory unit 17.
[0052] The load waveforms include load waveforms corresponding to various modes, such as a "beginning high mode" and a "final high mode." In the "beginning high mode," the braking force reaches its maximum value in the first half of the user's stroke and gradually decreases to its minimum value. In the "final high mode," the braking force reaches its minimum value at the start of the user's stroke and gradually increases to reach its maximum value in the second half of the stroke.
[0053] The user achieves the training objective by selecting and executing a training mode according to the input training information.
[0054] After step S3, the user operates the load waveform displayed on the display 23 via the touch panel 22 so that the load waveform displayed on the display 23 becomes the desired waveform (S4).
[0055] 6 is a diagram showing the "peak change mode" displayed on the display 23 of the display device 20. The "peak change mode" is a mode for changing the position of the peak value, which is the maximum value of the braking force.
[0056] The user can adjust the magnitude of the peak value by moving the operation key 231 up and down on the touch panel 22, and can adjust the timing at which the peak value occurs by moving the operation key 231 left and right.
[0057] The user can also adjust any of the first set position P1 and second set position P2 displayed on the display 23 via the touch panel 22. The first set position P1 may be the starting point of the stroke, and the second set position P2 may be the end point of the stroke. The first set position P1 may be the starting point of the rise of the braking force, and the second set position P2 may be the end point of the fall of the braking force. The range from the first set position P1 to the second set position P2 may be set to a range in which the power of the control unit 15 is on.
[0058] In this way, the user can set a new load waveform by using the setting unit 16 to set the position of the peak value in the load waveform and the slope of the load waveform, or the first setting position P1 and the second setting position P2 of the load waveform and the slope of the load waveform, based on the operation of the touch panel 22.
[0059] 5, after step S4, the setting unit 16 sets a new load waveform changed by the user's operation (S5: setting step). After step S5, the control unit 15 stores the new load waveform set by the setting unit 16 in the storage unit 17 (S6).
[0060] The control unit 15 stores in the storage unit 17 the combination of the first set position P1 and the second set position P2 that define the new load waveform set by the setting unit 16, and the position of the peak value.
[0061] Specifically, the control unit 15 stores information regarding the first setting position P1 and the second setting position P2 that define the new load waveform and the position of the peak value in the memory unit 17 at multiple addresses prepared in advance for each training mode.
[0062] After step S6, the user operates start key 233 on display 23 via touch panel 22 to start load control unit 10 and begin training with training apparatus 100 (S7). In step S7, control unit 15 operates load control unit 10 in a training mode corresponding to the new load waveform.
[0063] After step S7, the control unit 15 controls the magnitude of the current flowing through the coil of the magnetorheological fluid device 14, for example, using PWM control, to adjust the strength of the magnetic field applied to the magnetorheological fluid 14 a, thereby changing the viscosity of the magnetorheological fluid 14 a. As a result, the control unit 15 controls the magnitude of the braking force so as to follow the new load waveform set in step S5 (S8: control step).
[0064] After step S8, the control unit 15 determines whether the training has ended by determining whether an operation to end the training has been performed on the touch panel 22 of the display device 20 (S9). When the user wishes to end the training, the user operates the touch panel 22 to stop the load control unit 10 via the communication unit 25.
[0065] The control unit 15 repeats step S8 until the training is completed (S9: NO), and when the training is completed (S9: YES), the control unit 15 displays the training results on the display 23 (S10), and ends the flow shown in Fig. 5. Fig. 7 is a diagram showing an example of the training results displayed on the display 23. This allows the user to check the training results.
[0066] [Effects of the Embodiment] According to the training system 1 of the embodiment described above, a load waveform corresponding to the training information input by the user to the touch panel 22 is displayed on the display 23, and a new load waveform is set based on the user's operation on the load waveform displayed on the display 23. The control unit 15 then controls the magnitude of the braking force in accordance with the new load waveform, thereby controlling the magnitude of the load applied to the user of the training device. This allows the user to easily make appropriate settings depending on the training purpose. Furthermore, by customizing the training mode, more personalized training can be performed. This improves the quality of training and increases the user's motivation.
[0067] Furthermore, with the load control unit 10, the control unit 15 can finely adjust the strength of the magnetic field applied to the magnetorheological fluid 14a, thereby changing the viscosity of the magnetorheological fluid 14a and accurately controlling the magnitude of the braking force in increments of 0.1 kg. This makes it possible to meet the high demands of users, allowing them to feel the small improvements they are making in their daily training, thereby maintaining their motivation.
[0068] In addition, the combination of the first set position P1 and the second set position P2 that define the new load waveform set by the setting unit 16 and the position of the peak value of the additional braking force is stored in the memory unit 17, so that the user can easily perform training using the new load waveform during the next training session or thereafter.
[0069] Furthermore, since information regarding the first set position P1 and second set position P2 that define the new load waveform and the position of the peak value of the additional braking force is stored in multiple addresses prepared in advance for each training mode, the new load waveform can be quickly read out from the memory unit 17 during the next and subsequent training sessions.
[0070] Furthermore, in display step S3, an optimal load waveform that takes into consideration the age and sex of the user, the type and position of the sport the user wishes to train, and the athlete the user is aiming to become can be displayed on the display 23. Furthermore, in setting step S5, the user can operate the load waveform on the display 23 using the touch panel 22 to set a new load waveform, thereby enabling more personalized training.
[0071] [Other Embodiments] In the above-described embodiment, the training system 1 is used by a user to perform training, but this is not limiting. For example, the user may use the training system 1 to perform rehabilitation, or to play a game.
[0072] In the above embodiment, the display device 20 is operated by the user, but it may also be operated by an instructor who provides training guidance to the user. This allows the instructor to easily set the load for one stroke of the user of the training device 100, making it possible to provide optimal training guidance to the user.
[0073] In the above embodiment, the control unit 15 controls the strength of the magnetic field applied to the magnetorheological fluid 14a to adjust the load applied to the user, but this is not limiting. For example, the load applied to the user may be adjusted by controlling an electric motor.
[0074] [Summary] A training system according to a first aspect of the present disclosure includes a load control unit that controls the load applied to a user of a training device and a display device capable of communicating with the load control unit.

[0085] With the above configuration, the display can show an optimal load waveform that takes into consideration the user's age and gender, the type and position of the sport the user wishes to train, and the athlete the user aspires to be. Furthermore, the user can perform more personalized training by manipulating the load waveform on the display to set a new load waveform.
