Description

  The present invention relates to an instrument for measuring the height from the ground near the grip end of a golf club or a simulated golf club.

  The inventors of the present application invented an apparatus for measuring a golf swing by fixing a motion sensor to a grip end of a golf club.

Here, a mobile phone with a built-in microcomputer is used as a receiver, and an inclination angle with respect to the central axis of the golf club shaft is calculated by a program incorporated in the mobile phone. That is, the motion sensor S functions as a tilt angle sensor with respect to the shaft center axis.

  2A is a plan view of the grip end height measuring tool X, FIG. 2B is a front view of the grip end height measuring tool X, and FIG. A side view and a bottom view of the grip end height measuring tool X are shown in FIG. The grip end height measuring tool X includes a laser distance measuring unit 10 and a pedestal unit 20. The laser distance measuring unit 10 includes a laser output unit 12 that irradiates the front surface of a casing 11 formed of a flat box with laser light from a laser diode, and a laser light receiving unit 13 that detects reflected light of the laser irradiated by the laser output unit 12. And a reflection time measuring means for measuring the time from the output of the laser beam to the reception of light is provided inside the casing 11. These structures are the same as those of a general laser distance measuring device. The casing 11 further includes a transmission means for transmitting the detected time information to the mobile phone.

  The pedestal portion 20 supports and fixes the bottom surface of the casing 11 and is composed of a disk having substantially the same diameter as the grip end end portion. The pedestal portion 20 fixes the casing 11 to the upper surface so that the casing 11 can freely rotate by gravity around a rotation axis that passes vertically through the center of the disk. Further, an engagement protrusion 22 is provided at the center of the bottom surface of the pedestal portion 20 so as to be fitted and fixed in a hole passing through the shaft center axis provided at the center of the upper surface of the motion sensor S. With such a structure, when the engaging protrusion 22 of the pedestal 20 is engaged and fixed in the hole of the motion sensor S, the laser output unit 12 of the laser distance measuring unit 10 maintains an angle of 90 degrees with respect to the shaft axis. However, it is supported so as to rotate around the central axis of the shaft so as to always face downward due to gravity.

  Next, a method of using the grip end height measuring tool X having the above configuration will be described. First, the user inserts the engagement protrusion 22 of the base portion 20 into the hole on the upper surface of the motion sensor S fixed to the grip end, and fixes the grip end height measuring tool X to the grip end. In this state, when the user holds the grip of the club and takes an address, the laser output unit 12 of the laser distance measuring unit 10 faces downward as shown in FIG. A plane including the locus and the shaft central axis is a plane perpendicular to the ground. In this state, the laser distance measuring unit 10 transmits the time until the distance D in FIG. 3 to the mobile phone. On the other hand, since the information about the inclination angle θ with respect to the central axis of the shaft is sent from the motion sensor S to the mobile phone, the height H in the figure is calculated by the software built in the mobile phone from these two data. Can do.

Here, the motion sensor S is used as an inclination angle sensor for measuring the inclination angle of the laser distance measuring unit 10 in the laser irradiation direction, but the inclination angle sensor is built in the casing 11 of the laser distance measuring unit 10. May be. In this case, without attaching the motion sensor S, the grip end height measuring tool X can be directly attached to the grip end of the club to measure the height from the ground at the time of address of the grip end.
Here, the laser irradiation direction of the laser distance measuring unit 10 is set to a direction perpendicular to the center axis of the club shaft, but as shown in FIG. 4, a constant angle α (0 <α <90 °).
And may be slightly inclined downward. In this case, as shown in FIG. 5, the height cannot be calculated only by the inclination angle θ, but since the angle α is known, for example, the height H is obtained from H = Dsin (α−θ) in FIG. be able to.

(Embodiment 2)
FIG. 6 is a perspective view showing a state in which the grip end height measuring tool Y according to the second embodiment is fixed to a golf club in which the motion sensor S is fixed to the grip end. The motion sensor S is the same as that according to the first embodiment. 7A is a plan view of the grip end height measuring tool Y, FIG. 7B is a front view of the grip end height measuring tool Y, and FIG. 7C is a grip end height measuring tool. A side view of Y is shown, and a bottom view of the grip end height measuring tool Y is shown in FIG.

  The grip end height measuring tool Y includes a laser distance measuring unit 10 and an aiming device 30. The laser distance measuring unit 10 has substantially the same structure as the grip end height measuring tool X according to the first embodiment, but is fitted and fixed to a hole passing through the shaft center axis provided at the center of the top surface of the motion sensor S on the bottom surface. For this purpose, an engagement protrusion 22 is provided. When the engaging protrusion 22 is engaged and fixed in the hole of the motion sensor S, the laser output unit 12 of the laser distance measuring unit 10 maintains an angle of 90 degrees with respect to the shaft central axis, and when a constant force is applied, the shaft It can be fixed at an arbitrary rotational position while rotating around the central axis and applying no force.

  The sighting device 20 is a thick plate body having an isosceles trapezoidal shape in plan view, and a groove 21 having an inverted triangular section is formed at the center of the upper surface. The edge line formed at the bottom of the groove 21 is gently inclined so as to approach the main body side toward the bottom surface. The sight 20 is arranged so that the apex of the groove 21 is just on the opposite side of the laser irradiation direction, and is located on an extension line extending the laser to the opposite side. When the extended line of the edge line of the groove 21 of the sight 20 is positioned on a plane passing through the center mark and the shaft central axis, the laser beam is present on this plane.

Next, a method of using the grip end height measuring tool Y having the above configuration will be described. First, the user inserts the engagement protrusion 22 into the hole on the upper surface of the motion sensor S fixed to the grip end, and fixes the grip end height measuring tool Y to the grip end. In this state, the user rotates the grip end height measuring tool positioning tool Y so that the sighting device 30 faces in the direction of the center mark M drawn on the grip G. When the center mark M of the grip G is viewed from the grip end side through the sighting device 30 in this state, the state is as shown in FIG. Normally, at this stage, as shown in this figure, when the line of sight is aligned with the edge line of the groove bottom of the sight 30, the line of sight does not coincide with the center mark M. Therefore, the grip end height measuring tool positioning tool Y is rotated and adjusted so that the edge line of the groove bottom of the sighting device 30 and the center mark M are aligned on the line of sight as shown in FIG. Thereby, the laser irradiation direction is directed to the side opposite to the center mark side in a plane passing through the center of the center mark M and the central axis of the club shaft. In this state, when the user grasps the grip of the club and takes an address, the center mark is positioned at the upper center of the grip. Therefore, as shown in FIG. 3, the laser locus output from the laser output unit 12 A plane including the shaft central axis is a plane perpendicular to the ground. Therefore, the height H in FIG. 3 can be calculated from the time for the laser beam measuring unit 10 to reciprocate the laser beam up to the distance D in FIG. 3 and the information about the tilt angle θ with respect to the shaft center axis by the motion sensor S. .
In the second embodiment, as in the first embodiment, an inclination angle sensor may be built in the casing 11 of the laser distance measuring unit 10, and the laser irradiation direction is set to a certain angle α (0). <Α <90) may be set slightly downward.

(Embodiment 3)
FIG. 9 is a perspective view showing a state where the grip end height measuring tool Z according to the third embodiment is fixed to the grip end of the golf club. 10A is a plan view of the grip end height measuring tool Z, FIG. 10B is a front view of the grip end height measuring tool Z, and FIG. 10C is a grip end height measuring tool. A side view of Z and a bottom view of the grip end height measuring tool Z are shown in FIG. The grip end height measuring tool Z includes a laser distance measuring unit 10, a horizontal support unit 40, and a pedestal unit 20.

  The laser distance measuring unit 10 has substantially the same structure as the grip end height measuring tool X according to the first embodiment. The horizontal support portion 40 includes leg portions 41 and 41 made up of a pair of plates that pivotally support both side surfaces of the casing 11 of the laser distance measuring portion 10 at positions from the rear end, and leg portions 41 and 41. It is comprised from the fixed plate 42 which consists of a disc body fixed on a lower end side, and it supports so that the laser irradiation direction of the laser distance measurement part 10 may face a lower side with gravity. The pedestal portion 20 has substantially the same structure as the grip end height measuring tool X according to the first embodiment, but instead of supporting and fixing the casing 11, the bottom surface of the fixing plate 42 of the horizontal support portion 40 can be freely rotated. To support. With this structure, when the engagement protrusion 22 of the pedestal 20 is engaged and fixed in the hole at the grip end, the laser output of the laser distance measuring unit 10 is rotated by the rotation by the pedestal 20 and the rotation by the horizontal support 40. The part 12 is supported so as to be directed vertically downward under gravity.

  Next, a method of using the grip end height measuring tool Z having the above configuration will be described. First, the user inserts the engagement protrusion 22 into the hole at the end of the grip end, and fixes the grip end height measuring tool Z to the grip end. In this state, when the user grasps the grip of the club and takes an address, the shaft support portions of the pedestal portion 20 and the horizontal support portion 40 are rotated naturally by gravity as shown in FIG. Since the laser irradiation direction is directed vertically downward, the height from the ground to the grip end can be measured by measuring the laser distance in this state.

(Embodiment 4)
FIG. 12 is a perspective view showing a state where the grip end height measuring tool V according to the fourth embodiment is fixed to the grip end of the golf club. FIG. 13A is a plan view of the grip end height measuring tool V, FIG. 13B is a front view of the grip end height measuring tool V, and FIG. 13C is a grip end height measuring tool. A side view of V and a bottom view of the grip end height measuring tool V are shown in FIG. The grip end height measuring tool V includes a laser distance measuring unit 10, a horizontal support unit 40, and an aiming device 30. The laser measuring unit 10 and the horizontal support unit 40 are substantially the same as those of the grip end height measuring tool Z according to the third embodiment. The difference is that the fixed disk of the horizontal support part 40 is formed to be slightly thicker, the engagement protrusion 22 is provided on the bottom surface, and the sighting device 30 is provided on the fixed disk 42. The configuration of the sighting device 30 is the same as that of the grip end height measuring tool Y according to the second embodiment. The sighting device 30 is arranged such that the edge line of the groove 31 is positioned on a plane that bisects the rotation axis in which the horizontal support unit 40 rotatably supports the laser distance measurement unit 10.

  Next, a method of using the grip end height measuring tool V having the above configuration will be described. First, the user inserts the engagement protrusion 22 into the hole at the grip end end portion of the golf club, and fixes the grip end height measuring tool V to the grip end. In this state, the user rotates the grip end height measuring tool positioning tool V so that the sighting device 30 faces in the direction of the center mark M drawn on the grip G, and measures the grip end height of the second embodiment. As with the tool Y, adjustment is made so that the edge line of the groove bottom of the sighting device 30 and the center mark M are aligned on the line of sight as viewed from the grip end side. As a result, the direction of the irradiated laser rotates in a plane passing through the center of the center mark M and the central axis of the club shaft. In this state, when the user grasps the grip of the club and takes an address, the center mark is positioned at the upper center of the grip, so that the plane including the center mark and the shaft central axis is a vertical plane with respect to the ground. That is, the laser irradiation direction is in the vertical plane. On the other hand, the laser irradiation direction of the laser distance measuring unit 10 is naturally directed vertically downward due to gravity in the plane of rotation by the horizontal support unit 40. As a result, the laser irradiation direction is vertically downward as shown in FIG. By measuring the laser distance in this state, the height from the ground to the grip end can be measured.

(Modification)
In the second and fourth embodiments, the sighting device is used as a reference unit for matching the position reference, but other mechanisms may be used. For example, as shown in FIG. 14, various modifications are conceivable, such as the indicator needle 51 extending parallel to the shaft center axis is supported by the support lid 52 and the tip position of the indicator needle 51 is positioned on the center mark M. It is done. Furthermore, even when the sighting device is used, the shape of the sighting device can be variously modified, and a scope type device or the like can also be adopted.
Further, in the third embodiment, the freely rotating rotation axes are two orthogonal axes. However, since the rotation axis may be substantially rotated between the shaft central axis and the orthogonal axis orthogonal thereto, the laser distance measuring unit 10 is a spherical joint. You may make it fix so that rotation is possible.
Furthermore, in each of the above embodiments, the case where the golf club is fixed to the grip end of the golf club has been illustrated. However, any other shape can be used as long as there is a clip end portion. Therefore, the golf club for practice and the grip portion of the golf club are simulated. It can be used as an input device for computer games. In addition, it goes without saying that an inclination angle sensor may be built in in advance.
