Description

  The present invention relates to an exercise device, a motion detection sensor, a motion detection device, and a motion analysis system.

  As a technique for analyzing and evaluating the movement associated with a swing such as a golf club, a baseball bat, a racket such as tennis, and a human body exercising using them, a method of analyzing based on an image captured by a camera is known. . Moreover, since there is a limit in accuracy in the analysis based on the image, it has been attempted to perform a more accurate motion analysis using a motion detection sensor including an acceleration sensor or a gyro sensor.

  There are various methods for attaching the motion detection sensor to the exercise equipment.

  For example, Patent Literature 1 discloses a sensor attachment for attaching a motion detection sensor to an exercise device. In Patent Document 1, the motion detection sensor is attached to the exercise equipment via a sensor fixture.

  Patent Document 2 discloses a sensor unit having an attachment structure including a holding portion that can accommodate a shaft of a golf club from the outer periphery in the radial direction.

  As shown in FIG. 1, the motion detection device 100 includes a motion detection sensor 10 and a golf club 20 (an example of an exercise device). FIG. 1 illustrates a state in which the motion detection sensor 10 is attached to the golf club 20.

  In the motion detection device 100, the motion (motion) of the golf club 20 is detected by the motion detection sensor 10 attached to the golf club 20. Here, the movement of the golf club 20 refers to movement of the spatial position of the golf club 20, change in shape, change in posture, rotation, vibration, and the like.

1.1.1. Golf Club FIG. 2 is a perspective view schematically showing the golf club 20 of the motion detection device 100 according to the first embodiment.

  As shown in FIG. 2, the golf club 20 has an exercise equipment part 22 and a sensor attachment part 24.

  The exercise equipment unit 22 is a part of the golf club 20 that is used for exercise (golf competition). The exercise equipment part 22 has a grip part 22a, a shaft part 22b, and a head part 22c.

  The grip part 22a is a part for a user to hold. The grip part 22a is attached to the shaft part 22b. The grip portion 22a covers the shaft portion 22b. The grip portion 22a is formed of an elastic member such as rubber or urethane elastomer, for example. In the illustrated example, the grip portion 22a is a rubber grip inserted into the shaft portion 22b. Although not shown, the grip portion 22a is tape-shaped and may be wound around the shaft portion 22b.

FIG. 5 is a perspective view schematically showing a state in which the motion detection sensor 10 is attached to the sensor attachment portion 24. 3 to 5, the exercise instrument unit 22 is partially omitted.

  As shown in FIGS. 3 and 4, the sensor attachment portion 24 and the exercise equipment portion 22 are provided integrally. Here, the sensor mounting part 24 and the exercise equipment part 22 are integrally provided that the sensor mounting part 24 and at least a part of members constituting the exercise equipment part 22 are combined into one. It means being done. For example, when the sensor mounting part 24 and at least a part of the exercise equipment part 22 are configured not to be detachable, the sensor mounting part 24 and the exercise equipment part 22 are integrally provided. I can say that. For example, when the sensor attachment part 24 and at least a part of the exercise equipment part 22 are integrally formed by insert molding or outsert molding, the sensor attachment part 24 and the exercise equipment part 22 are It can be said that they are integrated.

  In the illustrated example, the sensor mounting portion 24 and the grip portion 22a are integrally provided. When the sensor mounting portion 24 and the grip portion 22a are made of different materials, the sensor mounting portion 24 and the grip portion 22a are integrally formed by, for example, insert molding or outsert molding. Moreover, when the sensor attachment part 24 and the grip part 22a are the same materials, the sensor attachment part 24 and the grip part 22a are integrally molded by one metal mold | die, for example. Thus, the sensor attachment part 24 and the grip part 22a are integrally formed, and the sensor attachment part 24 and the grip part 22a are integrally formed. The sensor mounting portion 24 and the grip portion 22a may be integrally configured by being fixed with an adhesive, a screw, or the like.

  Although not shown, the sensor attachment portion 24 and the shaft portion 22b may be provided integrally.

  The material of the sensor mounting portion 24 is not particularly limited, and is, for example, polyethylene, polypropylene, polystyrene, polyvinyl chloride, polycarbonate, ABS resin, fluorine resin, acrylic resin, or a synthetic resin such as a copolymer thereof. . Further, the material of the sensor mounting portion 24 may be a metal. The material of the sensor mounting portion 24 may be different from the material of the grip portion 22a, or may be the same as the material of the grip portion 22a.

As shown in FIGS. 3 and 4, the sensor mounting portion 24 is fitted to the base portions 26 a and 26 b and the grooves 11 d and 11 e (an example of the first fitting portion, see FIG. 9) provided in the motion detection sensor 10. And the flange portions 28a and 28b (an example of the second fitting portion).

  The first base portion 26a and the second base portion 26b are respectively fixed to the grip portion 22a. The first base portion 26a and the second base portion 26b extend in parallel along the axis of the shaft portion 22b.

  The first flange portion 28a is provided on the first base portion 26a. The first flange portion 28a protrudes from the first base portion 26a. The second collar portion 28b is provided on the second base portion 26b. The second flange portion 28b protrudes from the second base portion 26b.

  The flange portions 28 a and 28 b function as fitting portions that fit into the grooves 11 d and 11 e provided in the motion detection sensor 10. By fitting the flange portions 28a, 28b and the grooves 11d, 11e, the motion detection sensor 10 can be stably attached to the golf club 20 so that the golf club 20 is not dropped, displaced, rotated, or the like.

  The details of attaching the motion detection sensor 10 to the golf club 20 will be described later in “1.1.3. Attaching the motion detection sensor to the golf club”.

  In the golf club 20 according to the present embodiment, the exercise equipment portion 22 and the sensor attachment portion 24 are integrally provided. Therefore, in the golf club 20 according to the present embodiment, when the motion detection sensor 10 is detached from the golf club 20 and the motion detection sensor 10 is attached to the golf club 20 again, the exercise equipment portion 22 and the sensor attachment portion 24 are integrated. Compared to the case where the movement detection sensor 10 is not provided, the displacement of the attachment position of the motion detection sensor 10 is small (or there is no displacement). That is, in the golf club 20 according to the present embodiment, the position reproducibility when the motion detection sensor 10 is detached and attached again is high.

  Therefore, according to the golf club 20 according to the present embodiment, it is not necessary to calibrate the motion detection sensor 10 every time the motion detection sensor 10 is attached to the golf club 20, and thus the number of times of calibration is reduced. be able to.

  The calibration of the motion detection sensor 10 refers to relative alignment of the detection axis of the motion detection sensor 10 with respect to the golf club 20. Calibration of the motion detection sensor 10 is performed by an arithmetic device (PC 700, see FIG. 28) described later. The arithmetic device is a device that analyzes the motion of the golf club 20 based on the detection result of the motion detection sensor 10. For example, the arithmetic unit uses the position of the head portion 22c of the golf club 20 at the time of addressing (at rest) as the origin, the target line indicating the target direction of the hit ball as the first axis, and the axis on the horizontal plane perpendicular to the first axis. A coordinate system (global coordinate system) is defined with the second axis and the third vertical axis. Thus, defining the global coordinate system is called calibration of the motion detection sensor 10.

  In the golf club 20 according to the present embodiment, the exercise equipment portion 22 and the sensor attachment portion 24 are integrally provided, so that the exercise equipment portion 22 and the sensor attachment portion 24 are not provided integrally. The motion detection sensor 10 can be more reliably fixed. Therefore, in the golf club 20 according to the present embodiment, it is possible to make it difficult for the motion detection sensor 10 to be displaced due to the inertial force or impact force applied to the motion detection sensor 10 by the swing of the golf club 20. Therefore, in the golf club 20 according to the present embodiment, for example, the motion detection sensor 10 does not need to be calibrated for each swing, and therefore the number of times of calibration can be reduced.

  In the golf club 20 according to the present embodiment, the sensor mounting portion 24 has flange portions 28 a and 28 b that fit into the grooves 11 d and 11 e of the motion detection sensor 10. Therefore, in the golf club 20 according to the present embodiment, the position reproducibility when the motion detection sensor 10 is detached and attached again can be easily increased.

  The motion detection sensor 10 includes a base (an example of a mounted part) 11, a cover 12, and a sensor part 13.

  The base 11 and the cover 12 constitute a housing. As shown in FIG. 10, the cover 12 is fixed to the base 11 with screws 14, thereby forming a housing having an internal space 10 a. In addition, the fixing means of the cover 12 to the base 11 is not limited to the screw 14, For example, adhesion | attachment may be sufficient, and if the base 11 and the cover 12 are formed with the plastic, fixation by welding is also possible. .

  The base 11 functions as an attached portion that is attached to the sensor attachment portion 24. The base 11 has grooves 11d and 11e (an example of the first fitting portion) that fit into the flange portions 28a and 28b (an example of the second fitting portion) of the sensor mounting portion 24. The motion detection sensor 10 is attached to the golf club 20 by fitting the grooves 11d and 11e of the base 11 to the flange portions 28a and 28b.

  As shown in FIGS. 7 and 9, the first groove 11 d is formed in the first protrusion 11 b provided on the base 11. The second groove 11 e is formed on the second protrusion 11 c provided on the base 11.

The motion detection sensor 10 is attached to the sensor attachment portion 24 by fitting the first groove 11 d and the second groove 11 e to the flange portions 28 a and 28 b of the sensor attachment portion 24.

  The openings in the X direction of the first groove 11d and the second groove 11e are formed to face each other. The first groove 11d and the second groove 11e are open in the -Y direction, and a groove wall 11f is formed in the opposite direction (+ Y direction) (see FIG. 10).

  The sensor unit 13 functions as a detection unit of the motion detection sensor 10. The sensor unit 13 includes a circuit board 13a and an electronic device 13b mounted on the circuit board 13a.

  The circuit board 13a is fixed to the surface 11a of the base 11 on the internal space 10a side by bonding or the like.

  A plurality of electronic devices 13b are mounted on the circuit board 13a. At least one of the electronic devices 13b is an inertial sensor such as an acceleration sensor or an angular velocity sensor. The sensor unit 13 is configured to analyze, for example, triaxial motion.

  The motion detection sensor 10 according to the present embodiment includes a base 11 as a mounted portion that is attached to a sensor mounting portion 24 that is provided integrally with the exercise equipment portion 22 (grip portion 22a). Therefore, according to the motion detection sensor 10 according to the present embodiment, it is not necessary to calibrate the motion detection sensor 10 every time the motion detection sensor 10 is attached to the golf club 20, so the number of times of calibration is reduced. can do. Further, according to the motion detection sensor 10 according to the present embodiment, the motion detection sensor 10 does not need to be calibrated for each swing, so that the number of times of calibration can be reduced.

  In the motion detection sensor 10 according to the present embodiment, the base 11 has grooves 11d and 11e that fit into the flange portions 28a and 28b provided in the sensor mounting portion 24. Therefore, in the motion detection sensor 10 according to the present embodiment, the position reproducibility when removing the motion detection sensor 10 from the golf club 20 and attaching it again can be easily increased.

1.1.3. Attachment of Motion Detection Sensor to Golf Club FIG. 11 is a diagram schematically showing how the motion detection sensor 10 is attached to the golf club 20. FIG. 12 is a schematic diagram illustrating a state in which the motion detection sensor 10 is attached to the golf club 20, and corresponds to FIG. FIG. 13 is a schematic diagram illustrating a state in which the golf club 20 is attached to the motion detection sensor 10, and corresponds to FIG. In FIG. 13, the illustration of the golf club 20 other than the first flange portion 28a is omitted.

  The movement detection sensor 10 is attached to the golf club 20 as shown in FIGS. 12 and 13 by moving the movement detection sensor 10 in the direction of the arrow with respect to the sensor mounting portion 24 of the golf club 20 as shown in FIG. As described above, the first and second flange portions 28a and 28b of the sensor mounting portion 24 are inserted into the first groove 11d and the second groove 11e of the motion detection sensor 10, and so-called slide insertion is performed. .

  Hereinafter, a state in which the first flange portion 28a is inserted through the first groove 11d will be described with reference to FIG. The same applies to the state in which the second flange portion 28b is inserted into the second groove 11e.

When the motion detection sensor 10 is moved in the arrow direction (−Y direction) with respect to the sensor attachment portion 24, first, the end portion on the + Y direction side of the first flange portion 28a of the sensor attachment portion 24 starts to be inserted into the groove 11d. The thickness (Z-direction thickness) t2 of the end on the + Y direction side of the first flange portion 28a is relative to the height s in the Z direction of the groove 11e.
t2 <s
It is formed to become. Thus, by making the thickness t2 of the end portion on the + Y direction side of the first flange portion 28a smaller than the height s of the groove 11d, it is possible to facilitate the incorporation at the start of insertion.

Further, when the first flange portion 28a is inserted into the first groove 11d, and the protrusion 29 provided on the first flange portion 28a hits the first protrusion 11b of the base 11 as shown in FIG. Is completed. In this state, the thickness t1 of the end portion on the −Y direction side of the first flange portion 28a is
t1> t2
If the relationship is formed, the gap between the first groove 11d and the first flange portion 28a in the Z direction is narrower on the −Y direction side than on the + Y direction side. At this time, for example,
t1 ≒ s
Or t1> s
With this condition, the first flange portion 28a is sandwiched between the surfaces of the first groove 11d in the Z direction, and the movement detection sensor 10 can be prevented from falling off from the sensor mounting portion 24. Further, rattling in the Z direction of the motion detection sensor 10 with respect to the sensor mounting portion 24 is suppressed, and appropriate swing data of the golf club 20 can be obtained.

  The distance L1 between the first flange portion 28a and the second flange portion 28b shown in FIG. 11 is equal to the distance L2 between the first groove 11d and the second groove 11e shown in FIG. 12 (L1 = L2), for example. ).

  Here, the distance L1 is more specifically the distance between the tip end portion of the first flange portion 28a and the tip end portion of the second flange portion 28b. The front end portion of the first flange portion 28a is a portion located on the bottom side (−X direction side) of the first groove 11d when fitted into the first groove 11d. The tip of the second flange portion 28b is a portion located on the bottom side (+ X direction side) of the second groove 11e when fitted in the second groove 11e. The distance L2 is a distance between the bottom of the first groove 11d and the bottom of the second groove 11e.

  If the flange portions 28a, 28b and the grooves 11d, 11e can be fitted, the distance L1 between the first flange portion 28a and the second flange portion 28b is equal to the first groove 11d and the second groove 11e. The distance L2 may be smaller than L2 (L1 <L2).

  Further, for example, the distance L1 between the first flange portion 28a and the second flange portion 28b may be larger than the distance L2 between the first groove 11d and the second groove 11e (L1> L2). In this case, by using the base portions 26a and 26b as elastic bodies, in a state where the flange portions 28a and 28b and the grooves 11d and 11e are fitted (see FIG. 12), the distance between the flange portions 28a and 28b is increased.

The second communication unit 710 includes a reception unit 711 that receives data transmitted from the first communication unit 130 of the motion detection sensor 10, and a transmission unit 712 that transmits data to the first communication unit 130. The motion analysis unit 720 performs data processing of the acquired detection data of the motion detection sensor 10 and analyzes the motion of the golf club 20. The motion analysis unit 720 calibrates the motion detection sensor 10 when analyzing the motion of the golf club 20. The display unit 700c displays the analysis result obtained by the motion analysis unit 720. The motion analysis system 1000 also includes a printer 800 for outputting the analysis results to the outside.

  Next, analysis of the motion of the golf club 20 in the motion analysis system 1000 will be described.

  When the golf club 20 to which the motion detection sensor is attached swings, the inertial sensor 110 detects the inertial force and sends detection data to the data storage unit 120. The data storage unit 120 processes the detected data into a data format that can be transmitted to the PC 700 and stores (stores) the data until a transmission instruction from the PC 700 is received. When a predetermined swing for motion analysis is completed, the motion analysis work is started. When the input unit 700a gives an instruction to start analysis to the processing unit 700b, the transmission unit 712 of the second communication unit 710 transmits a detection data transmission instruction to the first communication unit 130 wirelessly. Based on the command received by the reception unit 131 of the first communication unit 130, the detection data stored in the data storage unit 120 is transmitted to the processing unit 700b by the transmission unit 132.

The detection data received by the receiving unit 711 of the second communication unit 710 is sent to the motion analysis unit 720, and the motion analysis of the golf club 20 is executed based on a predetermined analysis program. The analysis result is displayed as an image on the display unit 700c of the PC 700, or is recorded and output on a recording medium by the printer 800 as an external output.

  The motion analysis system 1000 according to the present embodiment includes a motion detection sensor 10 and a golf club 20 having a sensor mounting portion 24 provided integrally with the exercise equipment portion 22. Therefore, in the motion analysis system 1000, it is not necessary to calibrate the motion detection sensor 10 every time the motion detection sensor 10 is attached to the golf club 20, and therefore the number of times of calibration can be reduced. In addition, according to the motion analysis system 1000 according to the present embodiment, the motion detection sensor 10 does not need to be calibrated for each swing, so that the number of calibrations can be reduced.
