Description

[Technical field]

[0001] The present invention relates to a training seat having a sensor. [Background technology]

[0002] Conventionally, devices that control the load according to the physical condition of a user are known as training devices used for rehabilitation, muscle training, etc. For example, Patent Document 1 discloses a device that attaches multiple measurement electrodes to the body and adjusts the load according to the pattern of acquired electrocardiogram waveform data (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-65504 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional training devices require sensors to be attached to the user's body to detect the user's physical condition, which can be inconvenient, making it difficult to relax while exercising and raising concerns about hygiene.

[0005] Therefore, an object of the present invention is to provide a training sheet that can acquire a user's biological information and use it for training without requiring the user to wear a sensor on the body during training.

[0006] Another object of the present invention is to provide a training sheet that can evaluate the user's exercise posture. [Means for solving the problem]

[0007] A training seat for solving the above-mentioned problems comprises a seat body, a sensor provided on the seat body for acquiring biometric information of a user sitting on the seat body, exercise equipment provided integrally or separately from the seat body for the user to exercise, and a control unit connected to the sensor. The control unit is configured to acquire biological information from the sensor, and notify the user of information related to the user's exercise status based on the biological information.

[0008] According to this configuration, the control unit notifies the user of information regarding the exercise status based on the bio-information acquired from the sensor, so that the user who is training can know the exercise status. And, since the sensor that acquires the user's bio-information is provided in the seat body, the user does not need to wear the sensor on his / her body. Therefore, the user can train in a relaxed state without worrying about the sensor. Also, since there is no need to wear the sensor on the body, there is no need to worry about hygiene.

[0009] In the above-mentioned training sheet, the sensor may include a pressure sensor, and the control unit may be configured to compare the pressure value with a predetermined standard to evaluate the exercise posture of the user.

[0010] According to this configuration, the user's exercise posture can be evaluated by comparing with a predetermined reference value and notified, so that the user can attempt training in an appropriate posture.

[0011] The training seat that solves the above-mentioned problems comprises a seat body, a sensor provided on the seat body for acquiring biometric information of a user sitting on the seat body, exercise equipment provided integrally or separately from the seat body for the user to exercise, and a control unit connected to the sensor and connected to the exercise equipment so as to control the load of the exercise equipment. The control unit may be configured to acquire biometric information from the sensor and control the load of the exercise machine based on the biometric information.

[0012] According to this configuration, the control unit controls the load of the exercise equipment based on the bio-information acquired from the sensor, so the user can train effectively with an appropriate load. Furthermore, since the sensor that acquires the user's bio-information is provided in the seat body, the user does not need to wear the sensor on his / her body. Therefore, the user can train in a relaxed state without worrying about the sensor. Furthermore, since there is no need to wear the sensor on the body, there is no need to worry about hygiene.

[0013] In the above-mentioned training sheet, it is preferable that the control unit reduces the load of the exercise equipment when it determines, based on the biological information, that the load of the user's exercise is greater than a predetermined reference value.

[0014] Furthermore, when the control unit determines, based on the biological information, that the load of the user's exercise is smaller than a predetermined reference value, it is preferable that the control unit increases the load of the exercise machine.

[0015] In the above-mentioned exercise sheet, the biological information may include at least one of pressure from the user, temperature, humidity, pulse rate, sweat, and the user's heart rate. Effect of the Invention

[0016] The control unit notifies the user of information regarding the exercise status based on the bio-information acquired from the sensor, so that the user who is training can know the exercise status. Since the sensor that acquires the user's bio-information is provided in the seat body, the user does not need to wear the sensor on his / her body. Therefore, the user can train in a relaxed state without worrying about the sensor. In addition, since there is no need to wear the sensor on the body, there is no need to worry about hygiene.

[0017] In addition, by comparing the user's exercise posture with a predetermined reference value and notifying the user, the user can attempt training in an appropriate posture.

[0018] Furthermore, the control unit controls the load of the exercise equipment based on the bio-information acquired from the sensor, allowing the user to train effectively with an appropriate load. Since the sensor that acquires the user's bio-information is provided in the seat body, the user does not need to wear the sensor on his / her body. This allows the user to train in a relaxed state without worrying about the sensor. Furthermore, since there is no need to wear a sensor on the body, there is no need to worry about hygiene.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Next, an embodiment of the present invention will be described in detail with reference to the drawings as appropriate. As shown in FIG. 1, the training seat 1 of this embodiment includes a seat body S, an exercise machine 10 provided separately from the seat body S and used by a user P to exercise, and a control unit 30.

[0021] In this specification, training includes both strength training for able-bodied individuals to increase muscle strength, and rehabilitation for individuals who have become physically disabled due to illness or accident to recover their motor skills.

[0022] 2, the seat body S includes a seat cushion S1, a seat back S2, and a headrest S3. The headrest S3 may not be provided, or may be integrated with the seat back S2.

[0023] The seat cushion S1, seat back S2 and headrest S3 are constructed by covering a frame (not shown) with a pad made of urethane foam or the like, and further covering the pad with a covering made of fabric, leather, artificial leather or the like.

[0024] The seat cushion S1 and the seat back S2 are provided with pressure sensors PS (PS1 to PS12), which are an example of sensors that acquire biological information of a user sitting on the seat main body S. The pressure sensors PS are disposed, for example, between the surface and the pad.

[0025] As an example, six pressure sensors PS are provided on each of the seat cushion S1 and the seat back S2. Specifically, the seat back S2 is provided with a pressure sensor PS1 at a portion corresponding to the right shoulder, a pressure sensor PS2 at a portion corresponding to the right back, and a pressure sensor PS3 at a portion corresponding to the right waist. The pressure sensors PS1, PS2, and PS3 are arranged in this order from top to bottom. In addition, the seat back S2 is provided with pressure sensors PS4, PS5, and PS6 symmetrically to the pressure sensors PS1, PS2, and PS3.

[0026] On the other hand, the seat cushion S1 is provided with a pressure sensor PS7 at a portion corresponding to the right buttock, and pressure sensors PS8 and PS9 at portions corresponding to the right thigh. The pressure sensors PS7, PS8, and PS9 are arranged in this order from rear to front. The seat cushion S1 is also provided with pressure sensors PS10, PS11, and PS12 symmetrically to the pressure sensors PS7, PS8, and PS9.

[0027] Returning to Fig. 1, the exercise machine 10 is, for example, a butterfly machine that mainly trains the pectoral muscles. The exercise machine 10 includes a frame 11, a movable part 12, a wire 13, a weight 14, and a load generator 21. A seat body S is fixed to the front part of the frame 11.

[0028] The movable part 12 is provided on the upper part of the frame 11 so as to be rotatable around a vertical axis. Two movable parts 12 are provided, one on the left and one on the right, and are provided in an arrangement suitable for the user P to perform opening and closing movements using the left and right upper arms. Each movable part 12 is provided with a pulley 15A to which a wire 13 is fixed, so that the pulley 15A rotates together with the rotation of the movable part 12.

[0029] One end of the wire 13 is connected to the pulley 15A, and the other end is fixed to the weight 14 and the load generator 21. Specifically, pulley 15B is provided behind pulley 15A on frame 11. Wire 13 is wound around pulley 15A and pulley 15B, and is redirected downward by pulley 15B. Weight 14 is passed through the portion of wire 13 that extends vertically, and wire 13 and weight 14 are fixed by fixture 14A.

[0030] The load generator 21 is, for example, a motor, and a pulley 21A is provided on a portion corresponding to the output shaft of the motor. An end of the wire 13 is fixed to the pulley 21A.

[0031] A bracket 19 is attached to the upper front end of the frame 11, and a display DSP is fixed to the bracket 19. The training seat 1 is provided with a switch (not shown) for starting the control unit 30 at an appropriate position, for example, near the display DSP.

[0032] The control unit 30 is connected to each pressure sensor PS. The control unit 30 is also connected to a load generator 21 of the exercise machine 10 so as to be able to control the load of the exercise machine 10. The control unit 30 is also connected to a display DSP so as to be able to notify the user P of the exercise status, advice, and the like.

[0033] The control unit 30 includes a CPU, a ROM, a RAM, etc., and is configured to be able to execute various processes by executing programs stored in advance.

[0034] The control unit 30 is configured to acquire biological information from the pressure sensor PS, and notify the user P of information related to the user's exercise condition based on the biological information. Specifically, the control unit 30 can obtain a heartbeat signal as one piece of biological information from a pressure change of the pressure sensors PS, particularly the pressure sensors PS2 and PS5 corresponding to the user P's back.

[0035] The control unit 30 controls the exercise load of the user P during training based on the heart rate N. For example, when the control unit 30 determines that the exercise load of the user P is smaller than a predetermined reference value N1 based on the heart rate N, the control unit 30 increases the load of the exercise tool 10. On the other hand, when the control unit 30 determines that the exercise load of the user P is larger than a predetermined reference value N2 based on the heart rate N, the control unit 30 decreases the load of the exercise tool 10. The reference value N2 is a value larger than the reference value N1. The exercise load can be adjusted by the load generator 21. The load generator 21 has a configuration similar to that of a motor, and therefore can generate resistance when the wire 13 is paid out from the pulley 21A, similar to a so-called regenerative brake. Note that, when starting training, the control unit 30 generates a load using the load generator 21. Therefore, when starting training, the user P performs training with a combined load of the load from the weights 14 and the load from the load generator 21.

[0036] Furthermore, the control unit 30 outputs the pressure values ​​acquired by each pressure sensor PS to the display DSP in the form of an image as the exercise status of the user P. At this time, areas with high and low pressure values ​​are displayed with different colors and saturation (brightness).

[0037] The control unit 30 is also configured to compare the pressure values ​​with a predetermined standard to evaluate the exercise posture of the user P. For example, the exercise posture can be evaluated by comparing the balance of the magnitudes of the pressure values ​​P1 to P12 acquired from the pressure sensors PS1 to PS12 with the balance of the pressure values ​​L1 to L12 when training on the butterfly machine in an ideal exercise posture.

[0038] To explain an example of this evaluation, first, since the pressure values ​​P1 to P12 vary greatly depending on the weight of the user P, the pressure values ​​P1 to P12 are normalized so that the total sum becomes a predetermined value. Then, the amount of deviation M of the balance between the ideal pressure values ​​L1 to L12 and the standardized pressure values ​​P1 to P12 is calculated. The amount of deviation M can be calculated, for example, as follows: M = (P1-L1) 2 +(P2-L2) 2 +···+(P12-L12) 2 It can be calculated as follows:

[0039] When the control unit 30 determines that the amount of deviation M is greater than the threshold value Mth, it displays a message on the display DSP indicating that the posture is not good and which part of the body is out of balance. The part of the body that is out of balance is determined by calculating each term (e.g., (P1-L1)) when calculating the amount of deviation M. 2 It is possible to determine this by the size of the

[0040] Next, an example of the process performed by the control unit 30 will be described with reference to FIG. As shown in Fig. 3, when training is started by the user P operating a switch or the like, the control unit 30 first acquires pressure values ​​P1 to P12 from the pressure sensors PS1 to PS12 (S101). Then, the control unit 30 calculates the heart rate N from the pressure changes of the pressure sensors PS2 and PS5 (S102). Then, the control unit 30 outputs an image of the pressure values ​​to the display DSP (S103). For example, as shown in Fig. 4, an image of the seat body S is output to the display DSP, and a rectangle filled with a darkness according to the magnitude of the pressure value is displayed at a position corresponding to each pressure sensor PS. Although not shown in FIG. 3, the control unit 30 controls the load generator 21 according to the set load value during training.

[0041] Next, the control unit 30 determines whether the heart rate N is smaller than the reference value N1 (S110), and if it is smaller (S110, Yes), increases the load value when controlling the load generator 21 (S111). If the heart rate N is not smaller than the reference value N1 (S110, No), the control unit 30 does not increase the load value.

[0042] Next, the control unit 30 determines whether the heart rate N is greater than the reference value N2 (S120), and if so (S120, Yes), reduces the load value when controlling the load generator 21 (S121). If the heart rate N is not greater than the reference value N2 (S120, No), the control unit 30 does not reduce the load value.

[0043] Next, the control unit 30 normalizes the pressure values ​​P1 to P12 (S130). Then, the control unit 30 calculates the amount of deviation M of the balance (S131) ​​and judges whether the amount of deviation M is greater than the threshold value Mth (S140). When the control unit 30 judges that the amount of deviation M is greater than the threshold value Mth (S140, Yes), it displays a message on the display DSP (S141). For example, as in the image of the seat body S shown in FIG. 4, if the balance of the pressure values ​​is stronger on the right side of the body, it is possible to display a message MSG such as "Your posture is leaning to the right" or "Stretch your upper body firmly."

[0044] After displaying the message MSG, or if the control unit 30 determines that the deviation amount M is not greater than the threshold value Mth (S140, No), it determines whether the training has ended in step S150 (S150). If it determines that the training has not ended (S150, No), it repeats the processing from step S101, and if it determines that the training has ended (S150, Yes), it terminates the processing.

[0045] According to the training sheet 1 described above, the following effects can be achieved. Based on the bio-information acquired from the pressure sensor PS, the control unit 30 visualizes the distribution of pressure values ​​as information regarding the exercise status and displays it on the display DSP to notify the user P, so that the user P who is training can know the exercise status.

[0046] Furthermore, the control unit 30 controls the load of the exercise machine 10 based on the biological information acquired from the pressure sensor PS, so that the user P can perform effective training with an appropriate load.

[0047] And since the pressure sensor that acquires the biological information of the user P is provided in the seat body S, the user P does not need to wear a sensor on his / her body. Therefore, the user P can train in a relaxed state without worrying about the sensor. Also, since there is no need to wear a sensor on the body, there is no need to worry about hygiene.

[0048] Furthermore, the control unit 30 evaluates the exercise posture of the user P by comparing it with a predetermined reference value Mth and notifies the user P as a message MSG on the display DSP, so that the user P can attempt training in an appropriate posture.

[0049] Although the embodiment of the present invention has been described above, the present invention can be practiced by appropriately modifying it as shown in the following other forms. In the following description, the same reference numerals are used to designate configurations that are substantially the same as those in the above embodiment, and the description thereof will be omitted. For example, in the above embodiment, the training seat 1 is provided with the exercise equipment 10 separate from the seat body S, but as in the training seat 1B shown in Fig. 5, the exercise equipment may be provided integrally with the seat body S. The training seat 1B has armrests 40 as an example of exercise equipment on the left and right sides of the seat back S2, and an ottoman 50 as an example of exercise equipment at the front end of the seat cushion S1.

[0050] The armrest 40 is rotatably supported by the seat back S2. A load generator 41 made of a motor is provided on the rotation shaft of the armrest 40.

[0051] The ottoman 50 is rotatably supported by the seat cushion S1. A load generator 51 made of a motor is provided on the rotation shaft of the ottoman 50.

[0052] The control unit 30 is configured to control the loads generated by the load generators 41 and 51 .

[0053] In such a training seat 1B, for example, a load is generated by a load generator 41 so as to urge the armrest 40 upward, and the user P can perform an exercise of lowering the armrest 40 with his / her forearm.

[0054] Furthermore, the training seat 1B can generate a load by using the load generator 51 to urge the ottoman 50 upward, and the user P can perform an exercise to lower the ottoman 50 with his / her lower legs. Conversely, when the user P is undergoing rehabilitation, the ottoman 50 may be used to support the user P when performing an exercise to lift his / her lower legs.

[0055] In the above embodiment, pressure is acquired as a signal for acquiring biological information, but temperature or humidity may be acquired. Also, the heart rate of the user P may be acquired by a physical quantity other than pressure, for example, light such as infrared light.

[0056] In the above embodiment, the control unit 30 and the display DSP are separate entities, but the control unit 30 and the display DSP may be integrated. For example, a smartphone or a tablet may be used as a combination of the control unit 30 and the display DSP.

[0057] In the above embodiment, only the pressure value is displayed on the display DSP as the exercise status, but other exercise status such as the heart rate and body temperature may also be displayed.

[0058] In the above embodiment, a sensor that acquires pressure at individual locations has been exemplified as the pressure sensor, but a pressure distribution sensor that measures the distribution of pressure may also be used as the pressure sensor.

[0059] In the embodiment, the sensor is provided under the surface of the seat, so to speak, built into the seat, but it can also be provided on the outside of the seat. In this case, the sensor can be provided so that its position can be adjusted according to the user's physique. For example, when using it for the first time, the user may attach the sensor to an appropriate position on the seat that suits his or her physique. The sensor may also be removably attached to the surface of the seat with a hook-and-loop fastener or the like.

[0060] In the above embodiment, a butterfly machine is exemplified as an exercise machine, but the type of exercise machine is not limited. For example, the exercise machine may be an air bike, or a wheelchair equipped with foot pedals like an air bike.

[0061] In the above embodiment, the load of the user's exercise is determined based on the heart rate, but the load may be determined based on the degree of posture disturbance. For example, the load may be determined to be low when the degree of posture disturbance is small, and the load may be determined to be high when the degree of posture disturbance is large. Furthermore, in the case where temperature is acquired as biological information, it can be determined that the load is large when the temperature, i.e., body temperature, is high, and that the load is small when the temperature is low. Furthermore, in the case where humidity is acquired as biological information, it can be determined that the load is heavy when the humidity, i.e., the sweating state, is high, and that the load is light when the humidity is low.

[0062] The exercise status data acquired by the training seat may be stored in a server or a terminal owned by the user. The exercise status data can be used to determine the user's athletic ability. For example, when training on another training seat, the control unit of the training seat can read the stored exercise status and set the load applied by the load generator to a level suitable for the user.

[0063] In the above embodiment, the training seat is provided with a seat back, but it does not have to be provided with a seat back.

[0064] In the above embodiment, the exercise status and the like are notified to the user by displaying the information on the display, but the information can also be notified by other means such as sound or Braille.

[0065] The elements described in the above-mentioned embodiment and modified examples may be implemented in any combination. [Explanation of symbols]
