Description

  The present invention relates to a system and the like.

  Conventionally, there is a swing sensor for detecting a golf swing trajectory (for example, a trajectory) attached to a golf club shaft (Non-patent Document 1).

  The swing sensor described in Non-Patent Document 1 is a sensor main body in which a mounting tool separate from the sensor main body is mounted in advance on the shaft of the golf club and is slid in the axial direction using a dovetail joint. It has a mounting structure that can be removed. In this mounting structure, sufficient play is formed in the dovetail joint in order to facilitate attachment and detachment of the sensor body. For this reason, thick and strong rubber bands are used for mounting the mounting tool so that the mounting tool does not loosen even when a centrifugal force due to the swing of the golf club is applied to the sensor body.

  The golf swing sensor described in Non-Patent Document 1 wirelessly transmits data such as acceleration measured by a built-in sensor during a club swing to a mobile terminal, and uses application software downloaded to the mobile terminal side to detect a swing trajectory or the like. Analyze.

  Taking golf practice as an example, it is important to capture the ball with an accurate head speed, an accurate swing path, an accurate face path, and an accurate loft angle. However, there is a problem that only a rough estimation calculation using acceleration data or the like can be performed, and the trainer function is not sufficient.

  Accordingly, an object of the present invention is to improve the accuracy of information to be provided to a user.

  The system of the present invention, which has been made to achieve the above object, (A) obtains data necessary for specifying the trajectory and speed of the swing, and calculates and notifies information related to the trajectory and speed of the swing. An arithmetic processing means for performing the processing is provided, and each of the data is obtained separately by different detection means.

  According to the system of the present invention, data necessary for specifying the trajectory of the swing and data necessary for specifying the speed of the swing are separately acquired by separate detection means, and the arithmetic processing means is based on these data. The information about the trajectory and speed of the vehicle is calculated and notified. As a result, it is highly accurate information calculated based on the measured value. For example, in the conventional configuration for obtaining the speed from the trajectory of the swing, the obtained speed is only the estimated speed of the swing and the accuracy is poor. However, according to such a configuration, information on the speed is not merely estimated. It can also be configured.

  In the system of the present invention, (B) the arithmetic processing unit acquires data corresponding to the same swing from each of the detection units, and the trajectory and speed of the swing each time the swing is swung. It is good to have the structure that it is comprised as a means to calculate the information regarding.

  Information about the trajectory and speed of a swing when an object is swung once can be calculated with high accuracy, and notification is made based on the result of the calculation, so that it can be performed once from both the viewpoint of the trajectory and the speed. It is possible to give the user an opportunity to analyze and examine the swing. The “thing” to be swung may be, for example, a part of a machine or a part of a human body or an animal body. As a tool, it is preferable that a person swings using his / her body, and in particular, a sports tool.

  In these systems of the present invention, (C) the detection means for acquiring the data necessary for specifying the swing trajectory is attached to a swinging one, and the detection means for acquiring the data required for specifying the swing speed is It is good to adopt the configuration of being installed in another place other than the above.

  By attaching a detection means for acquiring data necessary for specifying the swing path of the swing to the object, the swing path of the object can be directly detected, and a detection means for acquiring the data necessary for specifying the swing speed is provided. By installing in another appropriate place other than the above, it is possible to objectively grasp the speed at which the object moves from the outside, and as a result, the swing trajectory and speed can be accurately detected. In particular, the “other appropriate location” may be a location that does not move, for example, at least with a swing, and preferably a location that does not move constantly.

In this case, at least one of the following (D) and (E) may be provided. (D) The arithmetic processing means performs control for determining and notifying whether or not the apparatus is in a state of being ready for the start of swing based on the acquired data.
(E) The arithmetic processing means performs control for determining and notifying whether or not the object has been swung based on the acquired data.

  By providing such a configuration, it is possible to notify the swing detection means attached to the object that the object has been prepared for the start of the swing or that the object has been swung.

  In these cases, it is preferable to further comprise (F) performing the notification from a part attached to the swing object.

  The swing detection means that has received the above notification performs a display based on the notification, so that it is possible to accurately notify the user who is about to swing the subject whether or not the swing may be started, and is useless. No measurement etc. can be performed. As a result, the detection accuracy is also improved.

  In addition, these systems according to the present invention can further (G) make the display processing means distinguish the overlap of the trajectory from the start of the swing to the end of the swing as the processing for the notification. It is good to also have the structure of performing the process which displays the information regarding the track | orbit of the said swing in a display mode.

  For example, in the case of golf swing practice, a single swing is constituted by an upswing and a downswing of a club, and the trajectories overlap. In such a case, the display mode can distinguish the overlap so that the user can accurately determine whether there is a point to be corrected in the upswing or a point to be corrected in the downswing. Become.

More specifically, it can be configured as in the following (G1) to (G3).
(G1) The arithmetic processing means performs a process of changing the display color of the trajectory from the start of the swing to the end of the swing gradually or step by step as the display mode.
(G2) The arithmetic processing means performs a process of changing the display color at the inflection point of the trajectory from the start of the swing to the end of the swing as the display mode.
(G3) The arithmetic processing means performs a process of displaying the trajectory from the start of the swing to the end of the swing as a moving image as the display mode.

  According to the configurations of (G1) and (G2), it is possible to easily understand which is the trajectory immediately after the start of the swing in the state where the entire swing trajectory is displayed by the color difference in the overlapping portion. According to the configuration of (G3), it is possible to distinguish, for example, a golf upswing and a downswing by displaying the moving image so as to draw a swing path. The configuration (G3) may be adopted together with the configurations (G1) and (G2). In this case, it is possible to distinguish the overlap from the entire drawn trajectory while feeling the change of the trajectory during the reproduction of the moving image, and to convey information to the user in a more easily understandable manner.

The system including the display means may further employ either (H) or (I) or both.
(H) When the arithmetic processing means displays information about the trajectory of the swing on the display means, the display is such that the ball before being hit by the object is shifted to a predetermined direction with respect to the center of the screen. Process to display in the form.
(I) When the arithmetic processing means displays information on the swing trajectory on the display means, the ball before being hit by the object and the standing position of the person who swings the object are at the center of the screen. On the other hand, display processing is performed in a display mode distributed in a predetermined direction.

  By adopting such a configuration, it is possible to display such as drawing a swing trajectory by effectively using the width of the screen of the display means. For example, in the case of golf swing practice, when the display with the ball positioned at the center of the screen is performed, the swing trajectory becomes a small display as a whole and wins. On the other hand, when adopting the configuration of (H) (I) This is because the swing trajectory can be drawn greatly.

  In the system including the display unit, (J) data necessary for specifying the swing trajectory is acquired at a sampling interval of 2 ms or less, and (K) the arithmetic processing unit is connected to the display unit. On the other hand, it is preferable to adopt a configuration in which the process of displaying the trajectory in a display mode representing a continuous change in the position corresponding to the sampling interval is performed.

  For example, taking golf swing practice as an example, the lowest point of the swing path is the position where the ball is met. In this case, when the sampling interval from the swing detection means is about 5 ms, the position of the lowest point cannot be accurately grasped, whereas the detection signal from the swing detection means is 2 ms or less, more preferably 1 ms or less. This is because the accuracy of capturing the position of the lowest point is increased by acquiring the position, and the swing trajectory at the moment of impact can be more accurately transmitted to the user.

  By adopting such a configuration, it is possible to sufficiently display the trajectory until the ball is met and the follow-through after the ball is met.

  In the case where these practice modes are provided, it is preferable that the arithmetic processing means includes (64) a nice-on non-notification switching means for switching to a setting in which the nice-on notification means does not perform nion notification.

  Suitable for cases where nice-on notification is troublesome.

  Here, although the mounting structure described in Non-Patent Document 1 is easy to attach and detach the sensor body, it is necessary to mount the mounting tool so that the shaft of the golf club is tightened with a thick and strong rubber band. There is a problem such as requiring power in mounting.

  Therefore, if the object is to facilitate the attachment work when the object is attached to the rod-like portion of the object by the pulling force generated in the fastener, the following invention should be extracted from the following embodiments. You can also.

  The object mounting structure of the present invention made to achieve the above object is an object mounting structure in which a rod-shaped portion of an object is sandwiched between an object body and a fastener spanned on the back side of the object body. (1A) The fastener has one end side secured to the object body, and is stretched by the rod-shaped part when the other-end hanging ring is hooked on the object body latching part. (1B) At least one of the latching portion and the fastener is provided with a stretching force reducing structure for reducing a fastener stretching force required when the hanging ring portion is hooked on the latching portion. It is characterized by that.

  If it does in this way, the attachment operation | work at the time of attaching an object with the pulling force which arises in a fastener to the rod-shaped part of a target object can be made easy. For example, the fastener is easy to turn the back of the rod-shaped part, and when turning the back of the rod-shaped part and pulling the fastener, it is difficult for the object to shift with respect to the rod-shaped part, and the hanging ring part is locked on the object body side It is possible to easily hook the part.

  In the “configuration in which the rod-shaped part of the object is sandwiched between the object body and the fastener”, the object body and the fastener are not limited to the form in which they directly contact the rod-shaped part, but between the object body and the rod-shaped part. A form in which some kind of inclusion such as a non-slip sheet is sandwiched may be adopted, or a form in which some kind of inclusion is sandwiched between the fastener and the rod-shaped part may be adopted. You may employ | adopt the form which inserts inclusions about both a main body and a fastener.

  "The state in which the fastener is stretched by the rod-shaped portion" means that the thickness and diameter of the rod-shaped portion of the object sandwiched between the object body and the length from one end side to the other end side of the fastener, This means a state caused by a relationship in which a tensile force is generated in the fastener when the fastener is turned on the back side of the rod-like portion and finished on the latching portion of the object body.

  Examples of the “object” and “bar” include a golf club shaft, a tennis racket shaft, a baseball bat, a throwing spear, a bicycle frame, a car engine propeller shaft and a connecting rod. be able to.

  Examples of the “fastener having a hanging ring portion” include a rubber ring, a perforated band rubber, and a rubber string provided with a ring. The material is not limited to rubber, and may be synthetic resin or a coil spring.

  Examples of the “holding portion” include a hook-like hook, a hook-like pin, and the like that are provided so as to project from the object body, and a slit that is formed so as to cut into the object body from the front side. it can.

  Examples of the “stretching force reducing structure that can be provided in the fastener” include, for example, reducing the wire diameter in a rubber ring and increasing the number of holes in a perforated rubber band.

  In addition, the “stretching force reduction structure that can be provided to the latching device” includes provisional pawls that protrude in a direction other than the direction in which the fasteners are stretched, or pivot from the rear to the front of the latching unit. For example, a lever or a slider that can be moved or slid can be provided as a temporary hook. In this case, the lever and the slider may be operated manually or may be operated electrically.

  In addition, as the “stretching force reducing structure that can be provided on both the fastener and the latching portion”, for example, the number of hooks is increased, and the number of holes of the perforated band rubber is increased accordingly. It is possible to reduce the area of the cross-section that supports the pulling force.

Here, the configuration (1B) is preferably as follows.
(2) As the structure for reducing the stretching force, a provisional hooking part for temporarily hanging the hooking part on the hooking part is provided.

  By providing the configuration (2), it is only necessary to pull the fastener to the temporary hook portion when the object is attached, and the stretching force when the fastener is hooked can be reliably reduced. Since the work of extending the fastener after the temporary hooking is performed can be performed using the temporarily hooked portion as a fulcrum, it can be easily performed.

  For example, “the relationship between the temporary hooking portion and the main hooking portion may be set so that the stretching force is smaller in the temporary hooking state than in the main hooking state”. In this case, the “temporary hanging portion is configured to be pulled by a direction different from the direction in which the force is applied to the main hanging portion in the main hanging state” or “the temporary hanging portion is in a position where the main hanging portion is in the main hanging state”. For example, “the main hooking state is a state of being hooked to a plurality of parts, and the temporary hooking state is a state of being hooked to one part”.

In this case, the configuration (2) may be embodied as follows.
(3) A provisional hooking claw part for temporarily hanging the hanging ring part from a direction intersecting with a direction in which the fastener is routed is provided as a part of the hanging part as the temporary hanging part.

  Here, the direction of the pulling force to be generated in the fastener for sandwiching the rod-shaped portion of the object between the object body is the direction in which the fastener is routed. By providing the configuration (3), when temporarily hanging, the fastener is moved in a direction other than the direction in which the tensile force for clamping the rod-shaped portion between the object body and the fastener should be generated in the fastener. The temporary hooking operation can be easily executed. In addition, the direction in which the fastener is pulled in order to finish hooking the fastener on the latching portion after provisional hooking is also a direction in which the pulling force for pinching the rod-shaped portion between the object body and the fastener should be generated in the fastener. It is not necessary to match, and the bent portion in the stretching operation is formed by the temporary hooking claw portion, and thereafter, the stretching operation until the hooking is completed can be easily performed.

In this case, the configuration (3) may be embodied as follows.
(4) As the temporary hanging portion, a first axial hooking claw portion directed to one end of the shaft along the axial direction of the rod-shaped portion and a first portion directed to the other end of the shaft as the temporary holding portion. Provided with two axial hooking claws

  With the configuration (4), after pulling the hanging ring portion of the fastener so as to expand in the axial direction of the rod-shaped portion and temporarily suspending it on one of the axial hanging claw portions, it is directed toward the opposite axial hanging claw portion. In addition, when the hooks on the opposite axial hooking claws are finished, the fastener is firmly hooked between the axial hooking claws. Although the work up to the temporary hook and the work up to the end of the subsequent hook are easy, the fasteners are securely hooked so as not to be unintentionally removed. In this way, the effect of reducing the stretching force in the stretching work when hooking the fastener is more reliably exhibited. As a result, for example, it is not necessary to use a thick rubber band, and it is not necessary to have the latching portion projecting greatly to the side, and the effect of reducing the outer dimension of the object is also exhibited.

  In configuration (4), for example, a wall extending to the front side is not attached to the latching portion so that the fastener is not removed, but a protrusion in the vertical direction (axial direction of the rod-shaped portion) is attached and attached. It is preferable to have a structure in which the tension of the fastener is reduced to reduce the mounting force.

In this case, the following configuration may be provided.
(5) A gap that allows a finger to pass is provided between the axial hooking claws.

  This is because provision of the configuration (5) also facilitates the temporary hooking work and facilitates the work up to the completion of the hooking after the temporary hooking work.

Further, the configuration (2) may be embodied as follows.
(6) The stretch force reduction structure is movable between the temporary hooking position and the main hooking position, and is in a state in which the hanging ring portion of the fastener is hooked at least during the movement from the temporary hooking position to the main hooking position. It must have a moving force assist means that can do it.

  It is only necessary to temporarily hang the hook ring portion of the fastener on the moving force assisting means at the temporary hooking position, and then move the moving force assisting means to the main hooking position.

  The moving force assist means may be a manual type or an electric type, and may be a rotary lever type or a slide type as long as it can be moved from the temporary hooking position to the main hooking position.

  For example, “(6A) As the structure for reducing the stretching force, between the tilted position tilted to the back side and the raised position raised to the front side at an intermediate position in the axial direction of the rod-shaped portion of the latching portion. It is preferable to employ a configuration in which a rotating member that can be rotated at the tilted position to temporarily hang the hanging ring portion at the tilted position is provided.

  When the configuration (6A) is provided, the fastener is temporarily hung in a state where the rotating member is tilted to the collapsed position. First, the fastener is temporarily hooked on the rotating member. The temporary hooking of the fastener on the rotating member that is tilted to the back side can be performed without being strongly stretched. After finishing the temporary hooking, it is possible to extend the fastener with less force by using the lever principle by raising the rotating member. As a result, the stretching force as a human work has been sufficiently reduced. It will be a thing. Even when this configuration (6) is adopted, for example, it is not necessary to make it easy to pick with a thick rubber band.

  The rotating member can be constituted by a lever attached to the object. In addition, the fastener is not a special thickness shape, but a general-purpose O-ring. When this O-ring is hooked on the lever and the lever is raised, the lever is used to move the body to the golf club shaft, etc. It can be attached to the rod-shaped part. In the case of the above attachment method, the rubber has a special shape. In this case, a rubber part having a simple shape such as an O-ring can be used. It should be noted that parts and a structure for making the lever not to be detached by a force applied to the lever at the time of attachment to a golf club or the like are required, which may increase the number of parts and make the structure complicated.

These object mounting structures of the present invention preferably further have the following configuration.
(7) The fastener is constituted by an elastic ring-shaped member closed as a whole, and at least a part thereof is provided with an insertion opening having a size smaller than the cross-sectional dimension of the elastic ring-shaped member, and both axial positions of the rod-shaped portion The object is provided with a retaining part for preventing the locking corresponding to the latching part.

  By adopting the configuration (7), it is possible to perform a hooking operation in a state in which the fastener is firmly pulled in parallel in the vertical and horizontal directions using the temporary hanging state, and the object mounting state becomes more stable. . And, in order to achieve such a stable tension state, it is possible to complete the operation of hooking the fastener by using the lever principle from the temporarily hooked state or by extending in the axial direction which is not the final pulling direction. As a result, even if a relatively thin diameter is used, sufficient pulling force can be exerted to make the attachment of the object robust. As a result, for example, the present invention can be implemented using a general-purpose O-ring as a fastener.

Further, the configuration (2) may be embodied as follows.
(8) As the stretching force reducing structure, the fastener is constituted by a composite ring-shaped member having a plurality of closed openings arranged in the axial direction of the rod-shaped portion, and the latching portion is formed by the composite ring-shaped member. The free end side of each opening of the member is configured with a plurality of hanging claws that can be hooked as a hanging ring.

  As a specific example of the configuration (8), for example, a fastener that integrates a plurality of rubber bands may be imagined. As a result of having three or more portions extended parallel to the pulling direction, each diameter Even if it is thinned, the fastener can be hooked in a state where a firm tensile force is generated. By reducing the diameter of each part, the stretching force during the hooking operation is reduced. Moreover, even if one piece is cut, it is not released from the hooked state, so that the object does not fall off.

In this case, the following configuration is particularly preferable.
(9) The composite ring-shaped member has a structure in which three or more closed openings are arranged in the axial direction of the rod-shaped portion, and the latching portion has a comb-shaped structure having three or more hanging claw portions. Being.

  As a specific example of the configuration (9), there are four or more parts that exert a tensile force. As a result, even if one is cut, the remaining three can be securely attached. As a result, when the fastener is made of rubber parts, it can be made thinner. This is a result of firmly performing the role of the safety device with four or more parts that exert the pulling force. As a result, the outer dimensions of the fastener can be reduced. As a result, the entire object can be made small and compact.

Further, these object mounting structures of the present invention can further include the following configurations.
(10) The object includes a contact member that is compressed and deformed by a tensile force generated in the fastener on the back surface side.

  With the configuration (10), the compression of the abutting member on the back surface of the object increases the pinching of the rod-shaped portion, so that pressure contact due to friction in the mounting state can be expected, and the mounting state becomes more stable. . This contact member also functions as a slip stopper.

In this case, the following configuration can also be provided.
(11) The rod-shaped portion has an outer surface shape whose diameter varies depending on an axial position thereof, and the contact member includes a surface corresponding to the outer surface shape on the back surface side.

  By providing the configuration (10), it is possible to attach the object to the object more stably. For example, the shaft of a golf club is tapered so as to become thinner toward the head from the grip, or gradually becomes thinner with a step. Baseball bats gradually become thicker from the grip toward the tip. In the configuration (10), for example, the rubber applied to the club is inclined in accordance with the inclination of the shaft so as to correspond to the shaft of the golf club, so that the force with which the rubber is pressed when attaching to the club is made as constant as possible. Is. For example, the contact member may include an inclined surface or a stepped surface corresponding to the outer surface shape on the back surface side. In this way, when the rod-shaped portion has a tapered or stepped outer surface shape whose diameter varies depending on the position in the axial direction, the compression of the contact member on the back surface of the object causes a deformation between the object and the object. Maintaining high adhesion even when the diameter of the rod-shaped part changes in the axial direction by increasing the adhesion and making the back side of the contact member an inclined surface or a stepped surface. Thus, it is possible to prevent the object from being inclined and being attached in an unstable state in which a gap exists on the lower end side, for example.

When these abutting members are provided, the following configuration may be further provided.
(12) The contact member is detachably attached to the object.

  While the contact member has an effect of improving the adhesion between the object and the rod-shaped part, if the rod-shaped part does not correspond to the back surface of the contact part, there is a possibility that an unstable mounting state in which a gap is generated may occur. This is because the configuration (12) can be used to replace the contact member with the back surface corresponding to the outer diameter, taper angle, etc. of the rod-shaped portion of the object. By adopting a structure in which the contact member that prevents slipping can be easily removed, for example, a battery can be inserted in a portion where the contact member is attached, and the battery can be replaced. Also, for example, a rubber contact member suitable for each type of golf club can be prepared and replaced to increase the anti-slip effect when an object is attached.

In the case of including such a detachable contact member, it is preferable to further include the following configuration.
(13) The contact member is configured such that the amount of compressive deformation increases toward the outer side from the axis of the rod-shaped portion.

  The abutting member is different from the one in which a simple plate-like rubber is attached to the back surface of the object, and is abutted so that the amount of compressive deformation increases from the axial center of the rod-shaped part to the outer side, As a result of the contact member being more strongly compressed and deformed at both ends, a strong adhesion force is generated.

In this case, the following configuration may be further provided.
(13A) The abutting member is composed of an elastic member having a cross-sectional shape having a flat surface on the front side and a recessed surface on the back side, and a frame-like rib protruding toward the front surface around the flat surface. The object has a frame-shaped portion corresponding to the frame-shaped rib, and includes a housing having an internal structure in which a gap remains on the front side of the flat surface during the compression deformation, and the case side Components that are thicker than the height of the frame-shaped part are accommodated in a removable manner.

  According to the configuration (13A), the abutting member has a frame-like rib that abuts the frame-like portion on the housing side at a position close to both ends of the fastener, and the abutting member is relatively thick at this portion. Only the amount of compressive deformation increases. On the other hand, since the gap formed between the flat surface of the abutting member and the housing is not subjected to pressure, the components housed in the gap are not damaged by pressing, and the abutting member is removed to remove the gap. When taking out the internal component, the rear surface of the component has an edge protruding to the rear surface side from the frame-shaped portion of the housing, and can be easily removed by placing a finger on the edge.

These object mounting structures of the present invention preferably have the following configuration.
(14) The object is an exercise used so that the object swings, and the object is an electronic device having an electronic circuit built in the housing or an attachment for attaching an electronic device having the electronic circuit built in the housing. .

  As the object, it is preferable that the object is moved at least during normal use of the object. For example, it may be an object moved by a motor or the like, or an animal or a human body itself.

  The object may be an object to which a force that separates the object attached to the rod-shaped portion of the object from the rod-shaped portion of the object is applied particularly during normal use of the object.

  The object may be a thing that a person holds and moves a part of the object. It is especially good for exercise. In particular, a grip is provided as a gripping part, and it is preferable that the movement is used to grip and grip the grip. Examples of exercises used for gripping and swinging include golf clubs, tennis rackets, and baseball bats. A method of detecting the state of swing by a swing sensor or the like is advantageous in order to acquire a higher technique using these exercises. In this case, there is a method in which the state of swinging these exercises is photographed with a camera from the side, and analysis and analysis are performed with an image. In that case, photographing technology is required. On the other hand, if a sensor is directly attached to these moving objects, such a high imaging technique is not required. On the other hand, if the mounting state of the sensor directly mounted on the moving object is unstable, accurate detection cannot be performed. In this respect, the object mounting structure of the present invention facilitates the object mounting operation, so that the object can be mounted in a stable state at an appropriate position, thereby enabling swing detection with sufficiently high accuracy. To do.

In such an exercise, it is preferable to have the following configuration.
(15) The object includes a grip, and the electronic device includes a power switch and an on / off display LED on a surface facing the grip.

  When the configuration (15) is adopted, when operating with the power switch of an electronic device attached to an exercise object, this can be easily performed while holding the grip, and on / off as intended. Whether or not it is in a state can be easily confirmed while holding the grip, and there is an effect that it is easy to see. On the other hand, if the switch is not operated intentionally, the switch touches the body such as the thigh and other surrounding objects (simply referred to as “thigh” in this specification) carelessly. It does not happen that the switch is turned on / off.

In such an exercise, it is preferable to have the following configuration.
(16) The terminal included in the electronic device is covered with a terminal cover attached to the housing such that the hinge portion is on the front side and the knob is on the back side.

  In the configuration (16), in a state where the electronic device is attached to a moving object, the knob portion of the terminal cover faces the rod-shaped portion side, and the terminal cover opens unexpectedly by touching the thigh or the like. Because there is no. For example, by making the terminal cover difficult to open when attached to a golf club, it is possible to make it difficult to cause a situation in which the body accidentally hits something and the cover opens.

In this case, the following configuration may be further provided.
(17) The knob portion has an end portion that extends to the back surface of the object, and the end portion is sandwiched between the object and the rod-shaped portion when the object is attached.

  By providing the configuration (17), the terminal cover cannot be opened in the object mounting state, but the problem of inadvertent opening can be almost completely avoided.

Further, the object mounting structure of the present invention may further include the following configuration.
(18) An electronic device in which a contact member that is compressed and deformed by a pulling force of the fastener is detachably attached to the object from the back side of the object, and the object includes an electronic circuit in a housing. The replaceable component is housed in the casing so that the circuit portion is positioned on the rod-shaped portion while being movable in the axial direction of the rod-shaped portion.

In this case, the following configuration may be further provided.
(18A) The replacement part is provided with a part having a relatively high possibility of destruction at one end side in the axial direction of the bar-like part and a part having a relatively low possibility of destruction at the other end side in the axial direction of the bar-like part. The replaceable part is housed so that the part having a relatively high possibility of destruction is positioned on the side opposite to the direction of the force to be received when the object moves.

In this case, the following configuration may be further provided.
(18B) The replaceable part is a battery, and the battery includes a substrate as the part having a relatively high possibility of destruction.

  When the object is moved so as to swing around the rod-shaped part, a centrifugal force is generated outward from the center of rotation of the rod-shaped part, and when the object is moved in the axial direction of the rod-shaped part, inertia occurs in the direction opposite to the moving direction. Although the force is generated, the circuit part of the replacement part and the part that is relatively likely to be destroyed are located on the opposite side to the direction in which these forces act. You will not be hit by. For example, when a swing sensor is attached to a golf club as an object, centrifugal force acts in the head direction when the club is swung. For example, even if there is a component that is movable in the axial direction in the casing and is in a loosely stored state, an important circuit portion of the component is not abutted against the casing. As a result, for example, even if a replacement part such as a battery is easily exchanged and stored in the housing, the damage can be avoided.

In this case, the following configuration may be further provided.
(19) The replaceable part is a battery, and the lead wire connected to the circuit portion is housed together with the lead wire in a gap having a width that can be positioned on the side of the battery.

  In the configuration (19), the lead wire is intentionally lengthened to protect the circuit portion on the battery side, and since the lead wire is long, the replacement work is facilitated. It won't be damaged by being caught.

In addition, in the object attachment structure of this invention, it is good to provide the following structures further.
(20) The object is an exercise used by holding and gripping the grip, and the object is an electronic device in which a plurality of circuit boards connected by a board-to-board connector are housed in a housing. The front-side casing is configured by a back-side casing that fixes a circuit board on the back-side of the plurality of circuit boards, and a front-side casing that is attached so as to close the front of the back-side casing. In the state where the rib is formed so as to protrude toward the back surface, and the front housing is attached to the back housing, the rib is a front circuit among the plurality of circuit boards. The height must be in contact with the surface of the substrate.

  For example, when two circuit boards are installed in parallel in a casing of an electronic device such as a swing sensor attached to a golf club and connected by a board-to-board connector (BtoB connector), a BtoB connector is obtained by swinging the club. The connection is not loosened. As a result of the structure in which the rib of the front housing is in contact with the surface of the circuit board on the front side, even if a centrifugal force in the direction of loosening the connection acts on the circuit board, the force is applied by the rib. It is because it can catch.

Further, the object mounting structure of the present invention can further include the following configuration.
(21) The object is an exercise used by holding and gripping the grip, and the object is an electronic device in which a plurality of circuit boards connected by a board-to-board connector are housed in a housing. The front-side casing is configured by a back-side casing that fixes a circuit board on the back-side of the plurality of circuit boards, and a front-side casing that is attached so as to close the front of the back-side casing. A cushioning member that is in contact with the surface of the front circuit board among the plurality of circuit boards in a state of being attached to the rear case.

  Similarly to the configuration (20) in which the front-side circuit board is prevented from moving outward by the ribs of the front-side housing, the configuration (21) allows the cushion member to be connected to the front-side circuit. The movement of the board can be restricted, and the connection between the board and the board connector (BtoB connector) can be prevented from loosening.

Further, the object mounting structure of the present invention can further include the following configuration.
(22) The object is an exercise used by holding and gripping the grip, and the object is an electronic device in which a plurality of circuit boards connected by a board-to-board connector are housed in a housing. The plurality of circuits are composed of a back-side casing that fixes a circuit board on the back side of the plurality of circuit boards, and a front-side casing that is attached so as to close the front of the back-side casing. The substrates are bonded with a double-sided adhesive mat having a double-sided adhesive layer.

  The configuration (22) is different from suppressing / restricting the movement of the circuit board from the outside, but the double-sided adhesive mat is fixed to the back side casing so that the circuit board on the front side is going to move outside. By the action of attracting toward the circuit board on the back side, the movement of the circuit board on the front side is restricted, and it is possible to prevent the connection between the board and the board connector (BtoB connector) from being loosened.

Further, in the object mounting structure of the present invention having at least the configurations (1A) and (1B), the following configurations can be further provided.
(31) A tightening strength changing structure for changing the tightening strength of the fastener is provided.

  By providing a tightening strength change structure, it is possible to respond to usage that emphasizes the reduction of stretching force and usage that emphasizes the tightening force by appropriately changing the tightening strength of the fastener. . The tightening strength changing structure for changing the tightening strength of the fastener may be provided in the object body, but is particularly preferably provided in the fastener.

In this case, the following configuration can be further provided.
(32) The tightening strength changing structure has a stepwise tightening strength changing structure for changing the tightening strength step by step.

  By adopting a structure in which the tightening strength is changed in stages, the above-described switching of usage can be performed accurately.

In this case, the following configuration can be further provided.
(33) The stepwise tightening strength As the stepwise changing structure, the fastener is provided with a plurality of the hanging ring portions at different positions in the extending direction.

  Use one of the hanging parts to reduce the stretching force, make it easy to do the installation work, use another hanging part to increase the tightening force, and firmly against narrow objects It can be used to wear it.

Further, in the object mounting structure of the present invention having at least the configurations (1A) and (1B), the following configurations can be further provided.
(41) As the stretching force reducing structure, a cushion body having a thickness capable of compressive deformation when being clamped by the fastener is sandwiched between the object body and the object.

  The cushion body is compressed and deformed to reduce the stretching force during tightening work.After installation, the reaction force accompanying the compression deformation of the cushion body exerts the tightening force together with the tension reaction force of the fastener, and the stretching work is performed. In spite of being easy, it can be in a firmly attached state.

  According to the present invention, according to the system, the accuracy of information to be provided to the user can be improved.

  Hereinafter, as an embodiment of the object mounting structure of the present invention, several examples will be described in detail with reference to the drawings, taking a golf swing sensor mounting structure as an example. A golf swing sensor is a device that is mounted near the grip of a golf club shaft and measures acceleration information when the golf club is swung. Based on the acceleration information detected by the sensor, the swing software is used with a dedicated software. It is intended to correct the player's wrinkles by displaying the trajectory and displaying it.

  As shown in FIG. 1, the golf swing sensor mounting structure according to the first embodiment includes a shaft 3 a of a golf club 3 between the golf swing sensor 1 and a rubber band 2 spanned on the back side of the golf swing sensor 1. It is the attachment structure which pinches | interposes.

  In mounting, first, as shown in FIG. 1B, the rubber band 2 has one end 2a (hereinafter referred to as “original side end 2a”) as the left side surface of the rear housing 11 of the golf swing sensor 1. Are attached to the hooks 12a to 12c for holding the band formed so as to project laterally from the band. Then, the rubber contact member 20 attached to the back side of the golf swing sensor 1 is pressed against the shaft 3a at a position close to the grip 3b of the golf club 3, while the other end 2b (hereinafter referred to as the rubber band 2) "Free end 2b") is hooked on hooks 13a to 13c for latching formed so as to project laterally from the right side surface of the rear housing 11 of the golf swing sensor 3. As a result, as shown in FIG. 1C, the golf swing sensor 1 is connected to the golf club 3 shaft so that the shaft 3a of the golf club 3 is sandwiched between the rubber contact member 20 and the rubber band 2 from the front and rear. It is attached to 3a. In this state, a tensile force is generated in the extending direction of the rubber band 2, and a force to shrink against the tensile force acts as a force for tightening the shaft 3 a of the golf club 3.

  As shown in FIG. 2, the rubber band 2 has a shape having three openings 2 c to 2 e so as to be aligned in the vertical direction, and when the golf swing sensor 1 is attached to the shaft 3 a of the golf club 3. As a portion for generating a tensile force, four string-like portions 2f to 2i located above and below these three openings 2c to 2e are provided.

  In the present embodiment, the upper and lower openings 2c and 2e are oblong and elongated in the left-right direction having the same shape and the same vertical dimension (hereinafter referred to as “width”) and horizontal dimension (hereinafter referred to as “length”). It has a shape. The central opening 2d is a rectangular opening with four rounded corners that are equal in length to the upper and lower openings 2c, 2e and about twice as wide as the upper and lower openings 2c, 2e.

  The four string-like portions 2f to 2i arranged in the vertical direction have a circular cross section with the same diameter, and fill the adjacent R-angle portions of the openings 2c to 2e at the original end 2a. It is integrated. Accordingly, the original side ends 2a of the openings 2c to 2e are closed by vertical strings having the same diameter as the string-like portions 2f to 2i.

  The openings 2c to 2e are integrated by the flat plate-like portion 2j so as to fill the adjacent R-angle portions on the free end 2b side. The flat plate-like portion 2j has the same thickness as the diameter of the string-like portions 2f to 2i, and the upper and lower edges are semicircular edges that are continuous with the outer surfaces of the string-like portions 2f and 2i. And the bulging part 2k is integrally formed so that it may swell in the front-back direction at the end on the opposite side to the opening of this flat plate-like part 2j. The flat plate-like portion 2j has an area that can be picked by a finger, and the bulging portion 2k has front and back surfaces that are continuous from the free end side of the flat plate-like portion 2j, and gradually toward the free end. The wall thickness is increased, and the wall thickness is about three times the maximum, and plays a role of making it difficult for the fingers gripping the front and rear surfaces of the flat plate-like portion 2j to move in the free end direction.

  In the present embodiment, each opening 2c to 2e of the rubber band 2 configured in a composite ring shape is a hanging ring portion.

  As shown in FIGS. 3 to 8, the golf swing sensor 1 has an L-shape that projects laterally and bends forward so that each of the openings 2 c to 2 e of the rubber band 2 can be latched simultaneously. A rear case 11 provided with hooks 12a to 12c and 13a to 13c having a comb-like structure in which three comb teeth are arranged in the vertical direction in a cross section, and the front side of the rear case 11 is closed, and the rear case 11 And a front case 15 that forms a storage space for storing a substrate and the like.

  The front housing 15 is provided with a bowl-like outer surface 15a as a whole, and the upper portion is an upper tapered surface 15b having a concavity. A switch window 15d through which the power switch can be seen is cut out from the rear side of the upper end surface 15c, and a circular hole 15e through which the LED can be seen is formed at the lower front center of the upper tapered surface 15b. Further, a terminal window 15g through which the terminal can be seen is cut out from the rear side in the bottom surface 15f of the front housing 15.

  As shown in FIG. 3C, the hooks 12a to 12c and the hooks 13a to 13c protrude from the left and right side surfaces of the rear housing 11 so that the vertical position and the horizontal protrusion amount are symmetrical. Has been. Further, as shown in FIG. 3A and the like, the hooks 12a to 12c and the hooks 13a to 13c have the same amount of protrusion in the front-rear direction. As a difference, as shown in enlarged views in FIGS. 4A and 4B, the hooks 12a to 12c are provided with protrusions 14a to 14c for preventing the release on the inner surfaces of the front ends of the wall-like portions extending forward. Projected. The distance between the front ends of the projections 14a to 14c and the left and right side surfaces of the rear housing 11 is made smaller than the diameter of the front end 2a of the rubber band 2, and the rubber band 2 is connected to the hooks 12a to 12c. 1B, when the rubber band 2 is integrated with the golf swing sensor 1 and attached to the shaft 3a of the golf club 3, as shown in FIG. It is designed not to deviate from 1.

  The front housing 15 and the rear housing 11 are integrated with two screws to form the housing 10 as shown in the rear view of FIG. A rectangular recess 11 a for mounting the rubber contact member 20 is formed on the back side of the rear housing 11.

  The rubber contact member 20 has an outer shape that fits in the rectangular recess 11a, has a flat surface 21 on the front side, and a thick V-shaped groove 22 that runs in the vertical direction on the back side. It is configured as a rubber molded body. As shown in the enlarged views of FIGS. 4 (A) and 4 (B), the V-groove portion 22 has a contact surface 22b tapered rearward so that the groove bottom 22a becomes the back side as it goes down. It has become. This corresponds to the fact that the shaft 3a of the golf club 3 has a tapered outer surface shape such that the grip 3b side is thick and the head side is thin, as shown in FIGS. is there.

  Further, as shown in FIG. 7, the rubber contact member 20 is formed with engagement recesses 23 a formed by cutting out the side surfaces from the front to the middle of the back on the left and right upper and lower portions of the flat surface 21 on the front side. ing. A circular recess 23b located on the center line in the height direction of the upper one of the engagement recesses 23a is also formed so as to be recessed backward from the flat surface 23.

  The rectangular recess 11a of the rear housing 11 has a circular protrusion 11b protruding from the front to the rear, and an engaging protrusion 11c that protrudes inward from the left and right side surfaces. These engagement protrusions 11c are fitted with the engagement recesses 23a of the rubber contact member 20 so that the rubber contact members 20 are attached to the rectangular recesses 11a of the rear housing 11 so as not to come off. Is. Moreover, the circular protrusion 11b is for fitting and positioning with the circular recessed part 23b of the rubber contact member 20 in that case. As a result, the rubber contact member 20 separate from the housing 10 is positioned and fitted in the rectangular recessed portion 11a of the rear housing 11 so as to be prevented from being detached. It will be attached to the back side.

  In this attached state, as shown in FIGS. 4A, 4B, etc., the contact surface 22b of the rubber contact member 20 is positioned on the back side of the arcuate depression 11d formed in the rear housing 11. The thickness of the rubber contact member 20 is designed so as to achieve this state. Accordingly, in the attached state of FIG. 1C, the shaft 3a of the golf club 3 has a force that resists the compression of the rubber contact member 20 and a force that tries to contract against the pulling of the rubber band 2. It will be pinched from the front and back. At this time, the rubber contact member 20 is brought into a contact state by a line touch between the two contact surfaces 22b of the V groove 22 and the shaft 3a. Since the rubber contact member 20 has a sufficient thickness at the portion that is contacted by this line touch, the force against the compression described above can be sufficiently exerted. In addition, since both the contact member 20 and the band 2 are made of rubber, the frictional force stabilizes the mounting state of the golf swing sensor 1.

  Since the contact member 20 is made of rubber itself, it can be removed by bending it with a finger if necessary. Thereby, according to the kind of golf club, it can replace | exchange easily for what has the contact surface shape which improved the adhesiveness with a shaft.

  As shown in the exploded views of FIGS. 6 to 8, the golf swing sensor 1 includes a sensor substrate 31, a Bluetooth substrate 32, and a storage space formed between the front housing 15 and the rear housing 11, The battery 33 is assembled so as to accommodate the battery 33, and the rubber contact member 20 is provided on the back side.

  In this assembly, the sensor substrate 31 and the Bluetooth substrate 32 are assembled in a state of being integrated in parallel via the BtoB connector 34. At this time, the sensor substrate 31 is in a state where the front surfaces of the edges of the upper and lower cutout portions 31 a and 31 b that are in an oblique position are in contact with the rear end of the screw boss 15 h that protrudes from the inner surface of the front housing 15. And is fixed to the front housing 15 with screws.

  On the inner surface of the front housing 15, a horizontal rib 15 i that protrudes rearward is provided in the vicinity of the portion where the front surface of the Bluetooth substrate 32 is exposed. The height in the front-rear direction of the horizontal rib 15i is such that when the sensor substrate 31 is fixed to the front housing 15 with screws, the front surface of the Bluetooth substrate 32 assembled with the BtoB connector 34 just contacts the front surface side. Has been. As a result, the Bluetooth substrate 32 is assembled in the housing in a state where the front surface is pressed by the horizontal ribs 15 i of the front housing 15 and is not easily displaced in the front-rear direction.

  Further, at the time of this assembly, the tip of the light guide 35a of the LED component 35 provided on the upper front surface of the sensor substrate 31 faces the circular hole 15e of the upper tapered surface 15b of the front housing 15, and the sensor The front end of the operation unit 36 a of the slide switch 36 provided on the upper surface of the back surface of the substrate 31 protrudes from the switch window 15 d of the upper end surface 15 c of the front housing 15. Further, at the time of this assembly, the terminal cover 40 is also assembled so as to cover the USB terminal 37 provided at the lower part of the back surface of the sensor substrate 31 from below. The terminal cover 40 is attached to the housing 10 such that the hinge part 41 is on the front side and the knob part 42 is on the back side. At this time, the terminal cover 40 fits in a recess 15k formed around the terminal window 15g on the bottom surface 15f of the front housing 15 and a recess 11k (see FIGS. 6 and 7) on the bottom surface of the rear housing 11, and the bottom surface. Is mounted so as to be substantially flush with the housing 10. As shown in FIG. 5B, the knob 42 of the terminal cover 40 can be opened by inserting a fingertip into the recess 11k extending to the bottom side of the bottom surface of the housing 10 and hooking it.

  The battery 33 is assembled so as to be housed in the battery housing frame 11m on the front surface side of the rear housing 11. Accordingly, the battery 33 is housed in the back side of the sensor substrate 31 and wiring connection to the sensor substrate 31 can be performed from the back side. If a connector is used for the connection portion, the replacement can be performed, and the rear housing 11 can be removed to easily perform replacement with a new one.

  According to the first embodiment described above, the rubber band 2 is provided with the three openings 2c to 2e, and the housing 10 is provided with the hooks 12a to 12c and 13a to 13c having comb-like structures having three comb teeth. The four string-like portions 2f to 2i of the rubber band 2 are provided by using the three openings 2c to 2e as hanging portions and hanging between the hooks 12a to 12c and the hooks 13a to 13c. As a result of the configuration in which the shaft 3a of the golf club 3 is sandwiched between the rubber contact portion 20 and the string-like portions 2f to 2i by the tensile force generated in the golf club 3, each of the string-like portions 2f to 2i is a thin rubber string portion. It can comprise, and the stretching force at the time of hooking on hook 13a-13c can be reduced. Further, the hooks 12a to 12c for holding are provided with protrusions 14a to 14c for preventing detachment, and the mounting operation can be executed after the detachment is prevented as shown in FIG. The operation of pressing the sensor 1 against the shaft 3a and turning the rubber band 2 to the back of the shaft 3a is easy to perform, and the sensor 1 is hardly displaced from the desired position in the operation of pulling the rubber band 2 after turning the back of the shaft 3a. As a result of reducing the stretching force, it is possible to easily perform the operation of hooking the hanging ring portion (the free end side of the openings 2c to 2e) onto the hooks 13a to 13c.

  Further, since the rubber band 2 includes four string-like portions 2f to 2i, even if one of them is cut, the other portion is connected, so that the sensor body is connected to the golf club 3. It can also be used as a safety device. By giving the role of this safety device, the string-like portions 2f to 2i can be made thinner and the rubber band 2 can be made thinner, and as a result, the amount of protrusion of the hooks 12a to 12c and 13a to 13c can be reduced. And the effect of reducing the outer dimensions of the sensor body is also exhibited.

  Furthermore, in this embodiment, as a result of the shaft 3a being sandwiched between the rubber contact portion 20 and the rubber band 2 on the back side of the sensor main body, a firm attachment state can be realized by the frictional force between the rubber and the shaft material. In addition, since the rubber contact portion 20 is provided with the contact surfaces 22b and 22b corresponding to the taper of the shaft 3a of the golf club 3 that becomes thinner toward the front, the rubber contact member 20 is provided with the shaft 3a. The force that is pressed onto the sensor becomes constant, and problems such as the sensor being tilted can be prevented.

  Further, since the power switch 36 is located on the upper end surface 15c of the sensor body, it is easy to perform a switch operation while holding the grip 3b of the golf club 3, and the switch is switched by touching the thigh carelessly. It is difficult to cause problems. In addition, as a result of being able to look into the LED from the upper tapered surface 15b, the state of the power source can be easily confirmed even while holding the grip 3b of the golf club 3.

  Further, since the terminal cover 40 is mounted so that the hinge part 41 is located on the front side and the knob part 42 is located on the back side so that the terminal cover 40 is flush with the bottom surface of the housing, the terminal cover 40 is placed on the thigh or the like. The problem of touching and opening carelessly is unlikely to occur.

  Further, the rubber band 2 is provided with a flat plate-like portion 2j and a bulging portion 2k on the free end side, so that it is easy to pick up with a finger and the picked-up finger is difficult to remove, improving the operability in the pulling operation. .

  Furthermore, the rubber contact member 20 that secures the difficulty of slippage due to friction when attached is not merely a tensioned rubber plate, but is contacted by a line touch at a position outside the shaft center of the shaft 3a. As a result of the sufficient thickness of the contact portion and the increased compressive deformation capability, the adhesion is improved.

  In this embodiment, since the battery 33 is mounted on the back side of the sensor substrate 31 so as to be housed in the battery housing frame 11m of the rear housing 11, the rear housing 11 may be removed to replace the battery. It is possible and the sensor 1 can be used for a long time.

  The Bluetooth substrate 32 assembled in the housing is detachable from the sensor substrate 31 by the BtoB connector 34, but is in a state of being abutted against the horizontal rib 15i of the front housing 15 in the assembled state. Even if the golf club 3 is swung, the golf club 3 is not displaced in the housing, and as a result, the BtoB connector 34 is not loosened, and the various functions of the sensor do not occur.

  Next, Example 2 will be described with reference to FIG. The second embodiment also relates to the mounting structure of the golf swing sensor, and the mounting target is the shaft portion of the golf club as in the first embodiment. The golf swing sensor 101 has substantially the same configuration as that of the first embodiment, and a sensor substrate, a Bluetooth substrate, and the like are accommodated in the housing 110 configured by assembling the front housing 115 and the rear housing 111. The switch is exposed from the upper end surface 115c, and the LED light guide is viewed through the upper tapered surface 115b. A thick rubber contact body 120 having a V-groove is detachably attached to the rear surface of the rear housing 111.

  The first difference from the first embodiment is that a rubber ring 102 using a general-purpose O-ring as shown in FIG. 9C is used as a fastener.

  Another difference is that the rubber ring 102 having a simple ring shape is used in the second embodiment, so that the rear casing 111 is used as a hook as a holding portion as shown in FIGS. 9A and 9B. The hook 112 having a large width in the vertical direction that protrudes leftward from the left side surface and bends forward is provided, and a plate-like protrusion 114 that protrudes inwardly in the middle of the vertical direction of the hook 112 is provided. The rubber ring 102 is configured to be held in a state where one end of the rubber ring 102 is prevented from coming off.

  Further, as one feature of the second embodiment, instead of the hooks 13 a to 13 c of the first embodiment, a latching portion 113 including a rotation lever 113 a is provided on the right side surface of the rear housing 111. The pivot lever 113a is a U-shaped spring steel mounted so as to be pivotable from the inside of the upper and lower bosses 113b, and is tilted to the rear side (FIGS. 9A and 9D). Can be rotated between the raised position raised to the front side (see FIGS. 9B and 9E), and at the raised position from the front side of the boss portion 113b to the rear. A structure that fits into the groove 113c formed so as to be cut toward the surface and does not accidentally come off is employed.

  In addition, the pivot lever 113a has a bent portion 113e on the root side so that the U-shaped main body 113d approaches the casing 110 at the raised position. Accordingly, the rubber ring 102 can be hooked to the outside of the boss portion 113b so as to be slid into the front position of the boss portion formed between the inner bent shape portion 113e and the housing 110. .

  For mounting, after the rubber ring 102 is kept from coming off the hook 112, the sensor is set so that the rubber contact member is pressed against the shaft 3a, and the rotating lever 113a is brought down to the collapsed position. While pulling the free end of the ring 102, it is hooked so as to be in a temporarily hooked state from the tip of the rotating lever 113a (see FIG. 9D). Next, the turning lever 113a is turned to the raised position (see FIG. 9E). As a result, with the lever principle, the rubber ring 102 can be stretched with a small force, and the rubber ring 102 is brought into the main hook state where the rubber ring 102 is caught on the outside of the boss portion 113b. And can be attached.

  In this embodiment, the assisting force of the rotating lever 113a is used to facilitate the mounting work of the rubber ring 102, and a general-purpose O-ring-like component can be used. This is a result of the fact that the rubber ring 102 can be firmly stretched without applying a large force by the lever principle, and even if a “large-diameter O-ring” or “small-diameter O-ring” is used. It is possible to reduce the force required for the person who performs the installation work to stretch, because the device can be restrained by firmly stretching with a small force.

  Next, Example 2 will be described with reference to FIG. The third embodiment also relates to a golf swing sensor mounting structure, and the mounting target is the shaft portion of the golf club, as in the first and second embodiments. The golf swing sensor 201 has substantially the same configuration as that of the second embodiment, and a sensor substrate and a Bluetooth substrate are accommodated in a housing 210 configured by assembling the front housing 215 and the rear housing 211. The switch is exposed from the upper end surface 215c, the LED light guide is viewed through the upper tapered surface 215b, and a thick rubber contact body 220 having a V-groove is detachably attached to the rear surface of the rear housing 211. It is.

  In Example 3, as in Example 2, a rubber ring 202 using a general-purpose O-ring as shown in FIG. 10B is used as a fastener. Since a simple ring-shaped rubber ring 202 is used, the hook serving as the holding portion protrudes leftward from the left side surface of the rear housing 211 and is bent upward in the same manner as in the second embodiment. A hook 212 having a large width is employed, and a plate-like protrusion 214 is provided so as to protrude substantially inwardly in the middle of the vertical direction of the hook 212 so that one end of the rubber ring 202 can be held off. did.

  On the other hand, the hook for latching is different from the second embodiment, and as shown in FIG. 10 (A), it protrudes rightward from the right side surface of the rear housing 211 and has an upward hooking claw portion 213m. Similarly, an upper hook 213a and a lower hook 213c that protrudes rightward from the right side surface of the rear housing 211 and includes a downward hooking claw portion 213n are provided. Note that a gap 213b is formed between the upper hook 213a and the lower hook 213c so that a finger can pass therethrough.

  For mounting, after the rubber ring 202 is kept from coming off from the hook 212, a sensor is set so that the rubber contact member is pressed against the shaft 3a. As shown in FIG. The free end side of the ring 202 is hooked on the upper hook 213a from above. This state is a temporarily hung state and can be implemented by slightly stretching the rubber ring 202. Thereafter, a finger is put on a part hanging from the gap 213b, and the lower hook 213n is pulled downward and hooked on the lower hook 213c so as to extend downward, and is brought into a main hook state. The operation of pulling down the rubber ring 202 after temporarily hooking on the upward hooking claw portion 113m is simplified as a result of forming the starting point of stretching by temporary hooking. As a result, the attachment work of the sensor 201 to the shaft 3a of the golf club can be easily performed.

  The temporary hook may be used as the lower hook 213c instead of the upper hook and pulled upward. In any case, instead of bending the hook end on the latching side forward to create a wall in the diametrical direction of the club shaft, attach a ledge in the vertical direction (the axial direction of the club shaft) In the third embodiment, the rubber ring 202 has a structure in which the pulling amount of the rubber ring 202 is reduced to reduce the force at the time of attachment.

  Next, Example 4 will be described with reference to FIG. The fourth embodiment also relates to a golf swing sensor mounting structure, and the mounting target is the shaft portion of the golf club as in the first to third embodiments. The golf swing sensor 301 is the same as that of the third embodiment with respect to the structure of the hook and the like. The difference is that, as shown in FIG. 11, a frame-like rib 326 protruding toward the front surface is provided around the flat surface 321 on the front surface side of the rubber contact member 320 and the rectangular shape of the rear housing 311 is provided. A frame-like portion 316 corresponding to the frame-like rib 326 is provided around the recessed portion 311a, and the rubber contact member 320 and the rear housing 311 are arranged so that the pressure at the time of sensor attachment is reduced by the frame-like rib of the contact member 320. The third embodiment is different from the third embodiment in that it is received by the frame-shaped portion 316 of the rectangular recessed portion 311 a of the rear housing 311. The configuration of the shape and the like on the back side of the rubber contact member 320 is the same as that of the third embodiment.

  As a result of adopting such a configuration, when the rubber contact member 320 is compressed and deformed, an internal structure in which a gap remains on the front side of the flat surface 325 is provided. Since this gap has a depth obtained by adding the height of the frame-like rib 326 and the height of the frame-like portion 316, instead of the battery 33 employed in the first embodiment, a plate-like battery 333 having a thickness that fits in this gap is used. The point of storing is also a feature of the fourth embodiment.

  The plate battery 333 includes a substrate portion 333a at one end in the longitudinal direction, and a lead wire 333b extended from the substrate portion 333a is connected to the sensor substrate via a connector 333c at the tip. It has become. The connector 333c has a structure in which a through window is formed in the lower part of the rectangular recess 311a, and the sensor board in the housing is detached therefrom.

  The thickness of the battery main body 333d of the plate battery 333 is larger than the height of the frame-like portion 316 formed on the rear housing 311 side, and a finger is applied when the rubber contact member 320 is removed. The configuration is easy. Further, the width of the plate battery 333 is narrower than the width of the gap in the left-right direction, and the length thereof is shorter than the length of the gap in the vertical direction, and is stored in a state of being movable in the axial direction within the gap. At this time, a lead wire 333b having a length that fits beside the plate battery 333 is employed with the substrate portion 333a facing upward.

  As a result, when the golf swing sensor 301 of Example 4 was attached to the shaft of the golf club and swung, centrifugal force was generated in the axial direction of the shaft from the grip toward the head, and the golf swing sensor was stored in the gap in a loose state. Although the plate battery 333 moves toward the lower side of the casing, the plate battery 333 is accommodated so that the easily damaged substrate portion 333a is located on the upper side. Therefore, the substrate portion 333a is the inner surface of the rectangular recessed portion 311a. It is not strongly pressed against. Further, since the pressure in the attached state is received by the frame-like ribs 326 on the rubber contact member 320 side that are in contact with each other around the gap, and the frame-like portion 316 on the rear housing 311 side, The substrate portion 333a is not damaged by the pressure at the time of attachment. Further, since the lead wire 333b is also placed beside the plate battery 333, it is not damaged by the pressure at the time of attachment.

  Next, Example 5 will be described with reference to FIG. The fifth embodiment is the same as the fourth embodiment except for the following points from the fourth embodiment. The difference is that the length of the knob 442 of the terminal cover 440 can be extended to the arcuate recess 411d of the rear housing 411. Accordingly, the golf swing sensor 401 can be attached so that the knob 442 of the terminal cover 440 is sandwiched between the shafts of the golf club, and the possibility that the terminal cover 440 may be inadvertently opened by hitting the thigh or the like is further reduced. It is a feature that can be done.

  The sixth embodiment is the same as the first embodiment, and as shown in FIG. 13, the golf swing sensor 501 further includes a cushion member 539 sandwiched between the front surface of the Bluetooth substrate 532. Thereby, the Bluetooth board | substrate 532 will be in the more stable attachment state. In this case, the mounting state of the Bluetooth substrate 532 is stable even without the horizontal rib 15i employed in the first embodiment.

  Example 7 is the same as Example 1, and as shown in FIG. 14, the golf swing sensor 601 is obtained by bonding a Bluetooth substrate 632 to a sensor substrate 631 with a double-sided adhesive mat 639. This also allows the Bluetooth substrate 632 to be in a more stable mounting state. Even in this case, the mounting state of the Bluetooth substrate 532 is stable even without the horizontal rib 15i employed in the first embodiment.

  The attachment belt 750 is a synthetic rubber injection-molded body for attaching the motion sensor main body 730 to the golf club. The angle adjustment bracket 770 is used by mounting the trainer device 710, and is used when the trainer device 710 is installed horizontally even in a place that is not flat.

  The motion sensor 730 has the same internal structure, outer surface shape, and the like as the golf swing sensor 1 described in the first embodiment. Then, by attaching the motion sensor 730 to a predetermined position of the golf club with the attachment belt 750 and using this system, the trainer device 310 can execute the process of displaying the swing path. With this system, the swing trajectory display can be switched from the rear view or the top view to a different view, and the head orientation at the moment of impact is recorded. It is configured to be able to do.

  As shown in FIG. 16, the attachment belt 750 has three horizontally long openings 752c to 752e arranged in the vertical direction from the original end 752a to the free end 752b. As a portion that generates a tensile force when attached to the shaft of the golf club, four string-like portions 752f to 752i positioned above and below these three horizontally long openings 752c to 752e are provided.

  These three horizontally long openings 752c to 752e are a first partition part 752m that reaches the inner surface of the string-like part 752i from the inner surface of the string-like part 752f at a position about 1/3 of the opening length from the original side end 752a, Three small openings 752c1 to 752c3 in the longitudinal direction are formed on the right side by a second partition part 752n that reaches the inner surface of the string-like part 752i from the inner surface of the string-like part 752f at a position that is approximately 1/4 of the opening length. It is divided into 752d1 to 752d3 and 752e1 to 752e3.

  Further, the upper and lower horizontal openings 752c and 752e have an oblong shape elongated in the left-right direction having the same vertical and vertical dimensions (hereinafter referred to as “width”) and horizontal dimensions (hereinafter referred to as “length”). It has become. The central lateral opening 752d has a rectangular shape with rounded corners such that the length is equal to the upper and lower lateral openings 752c and 752e and the width is approximately twice that of the upper and lower lateral openings 752c and 752e. Has become a department. Each of the small openings 752c1 to 752c3, 752d1 to 752d3, 752e1 to 752e3 is also a rectangular opening having four rounded corners.

  The four string-like portions 752f to 752i arranged in the vertical direction have an oval cross section having a long side that is approximately twice the diameter of the original end 752a having a circular cross section. It is configured to be thicker than that of the first embodiment so as to be flush with the original side end 752a and jump out to the front side. This pop-out amount is set to a size that does not cause a sense of incongruity as an amount that does not pop out beyond the bulging portion 752k. Further, these string-like portions 752f to 752i are integrated so as to fill the adjacent R-angle portions of the horizontally long openings 252c to 2522e while continuing to the portion constituting the original side end 725a at the original side end 752a. Yes.

  Each of the horizontally elongated openings 752c to 752e is integrated by a flat plate portion 752j so as to fill the adjacent R-angle portion on the free end 752b side. The flat plate-like portion 752j has the same thickness as the diameter of the original side end 752a, and the four string-like portions 752f to 752i have the back surface flush with the flat plate-like portion 752j and protrude to the front side. It is integrated with the flat plate portion 752j. A bulging portion 752k is integrally formed so as to bulge in the front-rear direction at a free end 752b that is the tip of the flat plate-like portion 752j. The flat plate portion 752j has an area that can be picked by a finger, and the bulging portion 752k has front and back surfaces that are continuous from the free end side of the flat plate portion 752j, and gradually toward the free end. The thickness is increased to a maximum of about three times the thickness, and plays a role of making it difficult for the fingers gripping the front and rear surfaces of the flat plate-like portion 752j to move toward the free end.

  In the present embodiment, the small openings 752c1 to 752e3 at the left end of the horizontally long openings 752c to 752e of the attachment belt 750 configured in a composite ring shape correspond to the hanging ring part. Further, in the present embodiment, as described later, the central small openings 752c2 to 752e2 can be used as the hanging part with the first partition part 752m regarded as the original end. In addition, although the small openings 752c3 to 752e3 at the right end can also be used as a hanging ring part in some cases, the second partition part 752n is mainly used to reinforce the string-like parts 752f to 752i in this embodiment. It is provided to stabilize how the string-like portions 752f to 752i extend in the length direction when the central small openings 752d1 to 752d3 are used as the hanging ring portions.

  As shown in FIG. 17, the motion sensor 730 has substantially the same configuration as the golf swing sensor 1 of the first embodiment. Similar components such as an L-shaped hook are denoted by the same reference numerals as those described in the golf swing sensor 1 of the first embodiment, and detailed description thereof is omitted. The motion sensor 730 has a rubber abutting member 735 mounted on the back side of the rear housing 11 having an arcuate groove 736 on its back side and a rectangular thickness of 5 mm so as to cover the entire back side. The difference is that a sponge body 737 having a size of 40.5 mm × 15 mm is attached. As shown in the cross-sectional view, the rubber contact member 735 has an edge 738 having a height of 1 mm and a thickness of 1 mm around the periphery, and the sponge body 737 is fitted inside the edge 738 to form an arc-shaped groove portion. Affixed on the entire surface along the arc 736. As a result of the sponge body 737 being affixed so as to fit inside the edge 738, even if the adhesive is peeled off during use, the edge is hardly lifted. By providing the rubber contact member 737 with the edge 738, the function and appearance of the sponge body 737 are not impaired.

  In the eighth embodiment, as shown in FIGS. 18A and 18B, the attachment belt 750 is formed such that its original side end 752a projects laterally from the left side surface of the rear housing 11 of the motion sensor 730. 18B. As shown in FIG. 18C, the sponge body 742 on the back surface of the motion sensor 730 is attached to the golf club grip 3b. While being pressed against the shaft 3a at a close position, the free end 752b of the mounting belt 750 is wound around the back of the golf club 3 so as to be wound while being pulled straight, and is extended laterally from the right side surface of the rear housing 11. The golf club is attached to the hooks 13a to 13c for hooking formed.

  In this embodiment, the club mounting surface of the motion sensor 730 is the sponge body 737, so that the pulling force generated on the attachment belt 750 and the compression force generated on the sponge body 737 act to cause the motion sensor 730 to move against the golf club 3a. Can be securely attached.

  As shown in FIGS. 18C and 18D, the appropriate mounting position is a position where the motion sensor 730 is located on the opposite side of the face surface and is about 2 cm below the grip 3b. Although it can be calibrated by calibrating the sensor mounting position, which will be described later, in measuring the swing trajectory of the club, it is better not to be too low from the grip 3b, and the optimal mounting range is 2 to 5 cm from the lower end of the grip. Range. At this time, the power switch 731 and the LED lamp 732 are attached so as to be positioned on the grip side.

  In addition, as shown by the lower arrow in FIG. 18B, the first partition part 752m is attached and used so as to be prevented from coming off from the band holding hooks 12a to 12c. It can also be installed to tighten more tightly.

  In using the trainer system of this embodiment, first, as shown in FIGS. 19A and 19B, a trainer device 710 and a motion sensor 730 are connected using an AC adapter 780 having a micro USB connector terminal 781. Charge from a household power source. At this time, the LED lamp 713 of the trainer device 710 and the LED lamp 732 of the motion sensor 730 are lit red during charging and blue when charging is completed. When charging is completed, the micro USB terminal 781 is removed and the covers 719 and 734 are firmly closed. Note that the trainer device 710 and the motion sensor 730 are configured to automatically stop charging when the battery is fully charged, and are not overcharged.

  In the trainer device 710, as shown in FIG. 20A, the cover 719 is opened, the micro SD card 790 is attached, and the cover 719 is firmly closed. Golf practice records can be stored on the micro SD card 790, and can be taken out and installed in a personal computer or the like. The angle adjustment bracket 770 includes a base 771 and a bracket 773 having a ball-like fitting portion 772 as shown in FIG. 20B, and the bottom surface of the trainer device 710 as shown in FIG. The protrusion 774 of the bracket 773 is inserted into the hole 710a provided in the mounting portion 710a. By mounting this angle adjustment bracket 770, as shown in FIG. 20 (D), the angle adjustment can be performed so that the trainer device 710 is rotated vertically and horizontally so that the main body is horizontal. Thereby, accurate measurement etc. can be performed even in a non-flat place.

  As shown in FIG. 21, the golf swing trainer system 700 of the present embodiment uses the display screen 711 of the trainer device 710 to set four items “head speed”, “estimated flight distance”, “ball speed”, and “meet rate”. A “swing mode” that can be displayed simultaneously and an “Arc mode” that displays a “swing trajectory” are provided.

  The “head speed” displayed in the “swing mode” is the club head speed, the “estimated flying distance” is the flying distance calculated from the club used and the head speed or the ball speed, and the “ball speed” is the ball speed. “Meet rate” represents the efficiency of the swing transmitted from the club to the ball by the numerical value of “ball speed ÷ head speed”. Further, the display can be switched to display of one horizontal item, history display, and graph display.

  The “Arc mode” is a mode performed by mounting the motion sensor 730, and can be switched to the display of “face trajectory” and “shot data” in addition to “swing trajectory”. The “exemplary” display for the “swing trajectory” can also be executed.

  As shown in FIG. 22, the golf swing trainer system 700 according to the present embodiment performs Bluetooth transmission / reception between the trainer device 710 and the motion sensor 730, so that the display screen 711 of the trainer device 710 has the above-described configuration. The system configuration can display such “Arc mode”.

  The trainer device 710 includes a Doppler sensor 721, an amplifier 722, a comparator 723, a first microcontroller 724, a second microcontroller 725, a display control unit 726, a recording unit 727, a switch group 728, and a transmission / reception unit 729.

  The Doppler sensor 721 is a microwave Doppler sensor having an output frequency of 24.15 GHz. An output signal of the Doppler sensor 721 (a signal corresponding to one movement of 6 mm of the golf club head) is amplified by an amplifier 722, compared with a reference value by a comparator 723, and a Doppler pulse (higher than the reference value). When the level is smaller than the reference value, it is output as a low level signal). This Doppler pulse is input to the first microcontroller 724.

  The first microcontroller 724 calculates a swing speed (head speed) based on the Doppler pulse. The signal amplified by the amplifier 722 is input to the second microcontroller 725.

  The second microcontroller 725 calculates the ball speed based on the Doppler signal amplified by the amplifier 722. The ball speed calculated by the second microcontroller 725 is input to the first microcontroller 724.

  The first microcontroller 724 calculates the estimated flight distance and meet rate based on the head speed calculated by itself and the ball speed calculated by the second microcontroller 725. The first microcontroller 725 performs display on the display control unit 726 and recording by the recording unit 727 based on the head speed, ball speed, estimated flight distance, and meet rate data. Note that the first microcontroller 724 executes display switching, mode switching, and the like in response to an input from the switch group 728. When the Arc mode is selected by the switch operation, the swing trajectory is calculated and displayed based on the detection signal from the motion sensor 730 received by the transmission / reception unit 729.

  In addition, the first microcontroller 724 is configured to also adjust the amplification factor for the amplifier 722. The first microcontroller 742 also performs processing such as a data transmission request to the motion sensor 730 via the transmission / reception unit 729.

  The motion sensor 730 includes a microcontroller 741, a sensor 742, an LED control unit 743, and a transmission / reception unit 745.

  The microcontroller 741 receives the detection signal of the sensor 742, executes necessary arithmetic processing, and transmits it through the transmission / reception unit 745. The signal transmitted from the transmission / reception unit 745 is received by the transmission / reception unit 729 of the trainer apparatus 710, and various displays in the Arc mode described above are executed. The sensor 742 is a sensor for detecting motion with three axes of acceleration and three axes of angular velocity. The microcontroller 741 also executes processing for responding to the data transmission request received from the trainer device 710 via the transmission / reception unit 745. Further, the microcontroller 741 controls the lighting / flashing state of the LED lamp 732 via the LED control unit 743.

  FIG. 23A shows the contents of lighting / flashing control for the LED lamp 732 by the microcontroller 741 of the motion sensor 730.

(1) In the “charging” state, “red” is lit.
(2) In the state of “charging (power on)”, “red” and “yellow” are alternately lit. In this case, the blinking pattern of “red” and “yellow” varies depending on the connection state of Bluetooth.
(3) When “charging completed” is entered, “blue” is lit.
(4) In the “charge complete (power on)” state, “blue” and “light blue” are alternately turned on. The blinking pattern of “blue” and “light blue” in this case varies depending on the connection state of Bluetooth.
(5) In the “charge abnormality” state, the light is turned “pink”. This is to notify the user of the possibility of temperature abnormality or overcharge.
(6) In the “power on (Bluetooth / not connected)” state, “green” blinks rapidly.
(7) In the “power on (Bluetooth pairing)” state, “green” is turned on and off slowly.
(8) In the “power on (Bluetooth / connected)” state, a pattern consisting of “green” lighting twice and turning off for a predetermined time is performed.
(9) Lights in “green” in the “motion detection in progress” state. This pattern is executed when the trainer device 710 is activated in the “swing mode”, “Arc mode”, or “practice mode” in the Bluetooth connection state.
(10) In the “motion calculation in progress” state, a pattern consisting of “green” lighting twice and turning off for a predetermined time is performed. “In motion calculation” is a state in which a swing trajectory is calculated after a swing. This is a display for making the next swing wait until the state of “9.

  The lighting pattern of the motion sensor 730 (9) “Continuous green lighting” indicates that the first microcontroller 724 of the trainer apparatus main body 710 detects the detection signal from the motion sensor 730 (transmitted at a sampling interval of 2 ms). Is started by notifying the motion sensor 730 by wireless communication that it is determined that “the user is almost stationary with the golf club held”. In addition, the blink pattern of the motion sensor 730 (10) “Turn green twice / turn off” indicates that the first microcontroller 724 of the trainer apparatus main body 710 determines that the “on ball” is based on the detection signal from the motion sensor 730. It is started by notifying by wireless communication that it is determined that the state is “the state where the impact is completed and the swing is finished”.

  Here, whether or not it is “almost stationary” means whether or not the user who has a habit of swinging the club back and forth after holding it will not cause chattering for the determination of the stationary state. The determination condition has a range. Further, “swing end” is determined using a detection signal corresponding to “impact of impact”. Therefore, in the case of “swinging”, it is determined that “still state is released” instead of “swing end”, but if it is held again and “still state” is taken, it becomes “continuous green lighting” state and the swing is measured immediately. It becomes possible to do.

  In this embodiment, in the trainer device 710, an icon 711b indicating the charging state of the motion sensor 730 and an icon 711b indicating the charging state of the motion sensor 730 are displayed on the display screen 711 as shown in FIG. The structure to do is also provided.

  As shown in FIG. 24A, the trainer device 710 is turned on by pressing and holding the power button 716 for 2 seconds or longer in the power-off state, and is held down for 2 seconds or more in the power-on state. The power is turned off. As shown in FIG. 24B, the motion sensor 730 is turned on by switching on the power switch 731. As described above, immediately after the power is turned on, the LED lamp 732 is in a “green blinking” state. Note that FIG. 24B illustrates a state where the power switch 731 is tilted to the off side.

  When the menu button 712 is pressed as shown in FIG. 24C after the trainer device 710 is powered on, a menu screen is displayed on the display screen 711. As shown in the figure, in this embodiment, “swing mode”, “Arc mode”, “setting mode”, “practice mode”, “Arc playback mode”, and “power off” can be selected from the menu screen. A mode can be selected by touching a mode button on the menu screen with a finger.

(1) The “swing mode” is a mode for detecting and displaying “head speed”, “estimated flight distance”, “ball speed”, and “meet rate” as already described. If a certain standard is satisfied, a “nice shot animation” is displayed. Further, the average value of the swing data for each club and the numerical value for each club can be displayed. Each item can also be displayed as a graph.
(2) “Arc mode” is a mode in which the motion sensor 730 detects and displays the club trajectory.
(3) “Setting mode” is a mode for changing settings of the main body such as date and left-handed setting.
(4) “Practice mode” is a mode in which the target distance setting is set automatically or manually. In this mode, “Nice On Animation” is displayed when a certain standard is satisfied.
(5) The “Arc playback mode” is a mode for playing back the recorded swing trajectory (Arc).
(6) When “Power Off” is touched, the power of the main body can be turned off without pressing the power button 716 for a long time.

  Before using this system, first set the date and time. By setting the date and time, the recording date and time can be added to the data detected by the golf swing. When checking with the data management software, it is possible to select files and compare data using the recording date and time as a mark. Note that immediately after the battery is mounted, the default setting is 0:00 on January 1, 2013.

  As for the operation method, as shown in FIG. 25A, the “setting” on the menu screen is touched and the right scroll is touched to display the “system tab”. Next, “General” is touched, “General” on the switched screen is touched, and “Date and time” is touched on the switched screen. Thereafter, the “ten-key”, “clear”, and “OK” are operated to input in the order of year, month, day, hour, and minute.

[Swing mode]
Next, the operation procedure of “swing mode” will be described. As shown in FIG. 25 (B), when “swing” on the menu screen is touched and the club button on the switched screen is touched, a club selection screen is displayed. In this embodiment, “Wood”, “Utility”, “Iron”, “Wedge”, and “Putter” are prepared as selectable club types. When selecting the first wood, as shown in the figure, touch “Wood” and touch “1W” on the switched screen.

  The “flying distance display” in the “swing mode” is calculated from the ball speed when the ball speed is detected. If the ball speed cannot be detected, such as a ball hit by a club (iron, wedge) with a large swing or a loft angle, it is calculated based on the head speed. Since the flight distance calculated from the ball speed takes into account the coefficient of restitution of the head and the ball, a more accurate numerical value can be calculated as compared with the flight distance calculated from the head speed.

Here, in the system of the present embodiment, calculation processing is performed in which the “flying distance calculation reference” is defined as follows.
(1) The calculation is based on coefficients obtained from a large number of data collections based on commercially available general clubs.
(2) The flight distance is calculated as a value including a run assuming an average spin amount, no wind, and flat topography.
(3) The directionality of the hit ball is not taken into consideration.
Depending on the club used, an error may occur between the flight distance display and the actual flight distance.

  In order to perform such flight distance calculation, in this embodiment, the type of club and the loft angle are preset in the storage device of the trainer device 710 as shown in FIG. In addition, about the wedge, the structure which can also change an initial setting value is employ | adopted.

  “Meet rate” is calculated as “ball speed ÷ head speed”. Generally, 1.56 is said to be the highest value (maximum coefficient of restitution of the ball). The “nice shot animation display” in the present embodiment is initially set to be displayed when the meet rate (ball speed ÷ head speed) is 1.40 or more. The “nice shot animation” is displayed only when a wood club is selected.

  Next, a procedure for executing the “swing mode” using the system of the present embodiment will be described. FIG. 26 shows the installation position of the apparatus when selecting a wood club. As shown in FIG. 26 (A), there is an obstacle between the trainer device 710 and the ball at a position about 1 to 1.5 m behind the detection sensor unit 715 of the trainer device 710 in the direction of launching the ball. Install horizontally. At this time, when the installation location is uneven, an angle adjustment bracket 770 is used (see FIG. 20D). The figure shows a right-handed case.

  As described above, the system according to the present embodiment can display a single item in a horizontal display in addition to the simultaneous display of four items. Basically, four items are displayed at the same time. As shown in FIG. 26B, when an item to be displayed is touched, the screen can be switched to a screen in which the item is displayed horizontally. Thereby, the user can often see the item he / she wants to know most from the standing position of FIG.

  When the user swings, the trainer device 710 performs arithmetic processing of head speed measurement, ball speed measurement, flight distance calculation, and meet rate calculation based on a signal from the Doppler sensor 721. While this calculation process is being performed, a message “Please wait” is displayed on the display screen 711. When the detection result is obtained, the detection result is blinked and then switched to lighting to notify that the result has been updated.

  In the present embodiment, a storage area is provided in the main body so that up to 500 detection results can be stored as a history. It should be noted that the history can be deleted by touching the detection result screen for 2 seconds after the detection result display changes from blinking to lighting.

  It is possible to display the head speed even by swinging. As mentioned above, even when the ball speed is not detected, it has a function to calculate the flight distance based on the head speed, but in the case of lightly swinging, the head speed is slow and the calculation is based on the head speed. When the flight distance is about 30 yards or less, the display is not performed.

  The detection result thus obtained can be recorded by associating the acquisition date and time with the detected data by performing “date and time setting” as described above.

In the following cases, it may not be displayed correctly.
(1) When the ball trajectory is high (launch angle is large) or deviates left and right, the ball speed may not be detected.
(2) A club with a large loft angle has a large launch angle, so the ball speed may not be detected. Further, the value of the meet rate is lowered.
(3) When a golf practice net or the like is used, the ball speed may not be detected if the distance from the ball placement position to the net is 3 m or less.
(4) When the ball speed is less than 20.0 m / s, it cannot be detected.
(5) It cannot be detected when the head speed is less than 15.0 m / s.
(6) If multiple units are used at short distances, they may not be detected correctly. Therefore, when using a plurality of units, it is desirable to keep the distance between them at least about 2 m.

  The “nice shot animation” shown in FIG. 26C is displayed only when a wood club is selected. In the initial setting, a “nice shot animation” is displayed when the meet rate is 1.40 or more. The “nice shot animation” employs a configuration that can be changed to “not display”.

  Next, the installation position of the apparatus when “Putter” is selected in “Swing mode” will be described. In this case, first, as shown in FIG. 27A, “swing” is touched on the menu screen, the club button is touched, and a putter is selected. Next, as shown in FIG. 27B, the trainer device 710 is separated from the ball launch line by about 20 cm on the opposite side of the user, and the rear end is about 20 cm away from the ball position in the launch direction. Is located, and the detection sensor unit 715 is installed so as to face about 1 m ahead in the ball launch direction. Also at this time, it is installed horizontally so that there is no obstacle between the trainer device 710 and the ball, and when there is undulation, the angle adjustment bracket 770 is used. This figure also shows a right-handed case.

  When the user performs putting, the trainer device 710 performs calculation processing of ball speed measurement and estimated flight distance calculation based on a signal from the Doppler sensor 721, and as a detection result, as shown in FIG. The estimated distance and ball speed are displayed. It should be noted that the display of the “Please wait” message during the calculation process and the switching from blinking to lighting when the detection result is obtained are the same as in the case of Wood.

In the measurement / calculation for this putting, the following conditions are adopted.
(1) Green speed (stump) is calculated assuming 7.8 feet.
(2) When the distance the ball has moved is short (about 1 m or less), it cannot be detected.
(3) Head speed cannot be detected.
(4) If there are moving objects or people near the detection area, accurate detection may not be possible. Conversely, if there are moving objects or people near the detection area, they may be detected and displayed based on those movements.
(5) The actual distance may not match due to turf, undulations, or other conditions.
(6) If multiple units are used at short distances, they may not be detected correctly. Therefore, when using a plurality of units, it is desirable to keep the distance between them at least about 2 m.

  The detection result obtained by performing the measurement or the like in the “swing mode” is stored in the storage area of the trainer device 710 as described above. Therefore, as shown in FIG. 28A, the “history display screen” can be called by touching the “history button” on the swing mode screen and touching the “history display” on the switched screen.

  The “history display screen” is configured to display seven items from the latest history, and by touching “next page”, the display switches to the next seven items. The illustrated example relates to No. 1 wood, “No.” in the upper row is a serial number where the latest in the history is 1, “H / S” is the head speed, “distance” is the estimated flight distance, “B / “S” means ball speed, and “meet” means meet rate. As a result of using a small screen, the item names are abbreviated, and a single display is displayed on a single line.

  In the top row, the average values of the head speed, ball speed, estimated flight distance, and meet rate are displayed. This average value is configured not to switch even if the “next page” or “previous page” is touched, and by comparing with the average value, it is possible to know whether or not each swing is possible.

  When the club button is touched and another type of club is selected, the history regarding the selected club can be confirmed. When no club is selected or all clubs are selected, the history is displayed in a state where no numerical value is entered in the average value column, as shown in FIG. Also, when only head speed is detected, such as swinging, the ball speed and meat rate are blank.

  As shown in FIG. 28C, when “Graph display” is touched on the history function selection screen, the screen is switched to the history date confirmation screen. When “Date and time” is touched, the screen is switched to the date designation screen, and the display target is selected by touching the date to be displayed in a graph. If “all” is touched on the history date confirmation screen, the date designation screen does not appear. In this embodiment, management is performed up to the date, and the hour and minute are not specified.

  When the date for graph display is selected in this way, a “history display item selection screen” is displayed as shown in the upper column of FIG. When the user touches any of “head speed”, “estimated flight distance”, “ball speed”, and “meet rate”, the screen is switched to a graph display screen corresponding to the touched item as shown in the lower column.

  Each graph is configured to display a maximum of 100 data on one page, and to read and display old data by touching the return button and new data by touching the feed button. . Further, the club can be selected from the graph display screen by touching the club switching button. Further, the display range of the vertical axis can be changed by touching the vertical axis setting button.

  Next, history storage will be described. As shown in FIG. 29A, “Swing” is touched on the menu screen, as shown in FIG. 29B, “History button” on the switched screen is touched, and “Save” is displayed on the history function selection screen. By touching, processing for storing history in the SD card is started in the trainer device 710. While the saving process is being executed, a message “During saving… Please do not remove the SD card” and a symbol indicating the progress of the process are displayed as shown in the figure. When saving is completed, the message “Finished” is displayed.

  When deleting the history, as shown in FIG. 29 (C), touch the “history button” and touch “delete” on the history function selection screen to ask “Do you want to delete the history?” In addition, “Yes” and “No” buttons are displayed for confirmation. Then, when “Yes” is touched, the history erasing process is started in the trainer device 710. When history deletion is completed, the message “History deleted” is displayed and the screen returns to the history screen after 2 seconds. Note that the screen returns to the history screen when “No” is selected for confirmation. When the history erasure is completed, the history number becomes zero.

[Practice mode]
Next, a procedure for executing the “practice mode” using the system of the present embodiment will be described. “Practice mode” is for practicing shots aiming at a set target distance, “automatic” for shooting at a target distance set at random, and shooting at an arbitrarily set flight distance There is “manual”. Touch “Practice” on the menu screen as shown in FIG. 30A, and touch either “Auto” or “Manual” on the opened screen as shown in FIGS. 30B and 30C. To do.

  When “automatic” is touched, the target distance is randomly set between 50 and 150 yards by internal processing of the trainer device 710. When “Manual” is touched, the target distance is input between 50 to 150 yards by operating the numeric keypad, and “OK” is touched to set. Regarding the upper and lower limits of the target setting distance, club selection, speed unit, flight distance unit, green radius, and nice on animation display, a settable range and initial setting values are defined as shown in FIG. The upper and lower limits of the target setting distance, the green radius, the speed and the distance unit can be changed by setting.

  When setting of the target distance is completed, as shown in FIG. 30E, the club button is touched to execute club selection. As shown, the putter is not in a selectable club. This is because the “practice mode” is a mode in which the estimated flight distance calculation function of the trainer device 710 is used to perform calculation processing for determining whether or not to display the “nice-on animation” in comparison with the target set distance.

  The installation position of the apparatus in the “practice mode” is the same as that in the “swing mode” as shown in FIG. 30 (F), and the detection sensor unit 715 of the trainer apparatus 710 is moved backward in the direction of launching the ball. It is installed horizontally at a position 1 to 1.5 m away so that there are no obstacles between the trainer device 710 and the ball.

  When the user swings, the trainer device 710 performs arithmetic processing of head speed measurement, ball speed measurement, flight distance calculation, and meet rate calculation based on the signal from the Doppler sensor 721 to detect the estimated flight distance. This detection result is displayed blinking on the display screen. When the estimated flight distance is within the target distance radius ± 10 yards, a “nice-on animation” as shown in FIG. 30G is displayed on the display screen. When the flashing of the detection result ends, the processing in the practice mode can be performed for the next ball. As described above, the green radius for the nice-on determination and the presence / absence of the nice-on animation display can be changed by setting.

[Arc mode]
Next, a procedure for executing the “Arc mode” using the system of this embodiment will be described. The “Arc mode” is a mode for recording a swing trajectory when swinging using the trainer device 710 and the motion sensor 730. The motion is temporarily stored for each swing, but disappears when the next swing is performed without saving. In order to save, the “Save” button is touched and saved for each stroke, and a maximum of 30 items can be saved in the storage device of the trainer device 710.

  First, as shown in FIG. 31A, the attachment is performed using the attachment belt 750 so that the upper end of the motion sensor 730 is positioned about 2 cm below the lower end of the grip 3b of the club to be used. At this time, the motion sensor 730 is mounted on the shaft 3a on the opposite side of the face surface, and the power switch 731 and the LED lamp 732 face the grip side.

  After the motion sensor 730 is attached to the club shaft in this way, club selection is performed next, and the sensor attachment position and the face surface are calibrated. As shown in FIG. 31B, this operation is performed by touching “Setting” on the menu screen and touching the feed switch on the setting screen to display the Arc tab as shown in FIG. After touching “Club” to display the club setting screen and selecting a club, touch “Sensor mounting position” and enter the sensor mounting position by numeric keypad input. The sensor mounting position can be calibrated within a range of 50 to 100 cm as a distance from the tip of the head to the motion sensor 730.

  When the calibration of the sensor mounting position is completed, as shown in FIG. 31D, the screen returns to the club setting screen, and “Face surface calibration” is touched. Then, the trainer device 710 displays on the display screen a screen showing a face surface calibration method in a diagram and text. The user performs an operation of touching “OK” with the club on which the motion sensor 730 is mounted in a state where the face is aligned with the horizontal plane, in accordance with the instructions on the screen and text. When “OK” is touched, the trainer device 710 communicates with the motion sensor 730 to calibrate the face surface. At this time, referring to the sensor attachment position data and the club selection data, processing for detecting the positional relationship between the motion detection position and the face surface by the motion sensor 730 is executed. When calibration is completed, a message to that effect is displayed. Note that when performing this operation, the power supply of the motion sensor 730 is also turned on.

  Next, as shown in FIG. 31 (E), as in the case of “swing mode”, the trainer device 710 is leveled on a flat place with no undulations so that there are no obstacles to the ball. Installed at a position of about 1 to 1.5m behind. In addition, by installing in this way, it will be in the state which can perform the measurement and calculation of "Arc mode" and "swing mode" simultaneously. Note that if the Bluetooth is connected between the motion sensor 730 and the trainer device 710, measurement and calculation in the “Arc mode” is possible. Therefore, for users who do not need data such as head speed, the installation method is not limited to the installation method of FIG. 31 (E), and the position where Bluetooth connection is possible in an environment where no obstacles or other radio waves are generated. It is sufficient if a trainer device 710 is installed in the vehicle.

  When the installation of the motion sensor 730 and the installation of the trainer device 710 are completed as described above, confirm that each power source is turned on, and touch “Arc” from the menu screen of the trainer device 710. , Set up a club. At this time, the LED lamp 732 of the motion sensor 730 is in a state of either “fast blinking of green”, repeated lighting and turning off once, repeating lighting and turning off twice, or continuous lighting.

  As shown in the table of FIG. 21 (A), “green” fast blinking is “Bluetooth not connected”, repeated lighting and turning off once is “bluetooth sparing”, turning on and off twice Is “Bluetooth connection is present” or “Motion calculation is in progress”, and the lighting continuation state is “Motion detection is in progress”. The motion detection can be performed by swinging in the “green” continuous lighting state. The user can execute the swing at any time after confirming the “green” lighting continuation state. The “green” lighting continuation state is a state in which the club is stationary based on a signal from the motion sensor 730 and the motion calculation process on the trainer device 710 side is not performed. Whether or not the club is in a stationary state is determined on the trainer device 710 side, and determination conditions are set so that the club can be determined to be in a stationary state even if the club is moved within a certain range. This takes into account that there are users who have a habit of moving the club slightly when taking the address posture.

  The user takes an address posture and performs a swing after confirming that the LED lamp 732 of the motion sensor 730 continues to be lit in green. When it is used for the first time immediately after the power is turned on, an image in a state where a person like the left side in FIG. 32B holds the club is displayed. The motion calculation is not executed even if swinging in this state. This is because for the motion calculation, calculation conditions that require impact on the ball are set in the trainer device 740.

  When the user swings and an impact on the ball occurs, the hit point is determined, and the trainer device 410 calculates the swing trajectory based on the sensor signals from the motion sensors 730 before and after that. Then, as shown in the screen on the right side of FIG. 32 (B), a moving image in which a person's image moves and a swing path is drawn is displayed as if the club is swung. This video display is played repeatedly, but not automatically saved. To save the swing path, touch the “Save” button on the screen. When the trainer device 710 detects a touch on the save button, the trainer device 710 saves data related to the swing trajectory currently being displayed. The maximum storable number in this embodiment is 30.

  When touching the screen repeatedly displaying the swing path, as shown in FIG. 32 (C), “front (from the top)”, “rear”, “upper surface”, “front” and the direction in which the swing path is displayed can be displayed. Switch to a different display. Each display is repeatedly played back as a moving image.

  Here, it is difficult to understand because the color cannot be displayed in the figure, but in this example, the display color of the trajectory from the start of the swing to the end of the swing is gradually changed from blue to yellow to red, and the upswing and downswing are changed. A display mode is adopted in which the distinction between the two can be determined by the hue. In the case of a golf swing, an inflection point from an upswing to a downswing occurs. Therefore, the inflection point is calculated and the upswing part is blue and the downswing part is red. The display mode may be changed. With these display modes, an upswing and a downswing can be distinguished even on a screen in a state where a swing trajectory has been drawn, and information for correcting the trajectory can be transmitted more accurately. In the present embodiment, since the process of drawing the swing trajectory is performed using a moving image, the upswing and the downswing trajectory can also be distinguished by this.

  In drawing the swing trajectory, in particular, the doll and the ball are distributed to the left and right with respect to the center of the display screen so that they can be clearly read from the “rear” and “upper surface” in FIG. A display mode that is shifted to the right side is employed. As a result, the swing trajectory can be drawn larger on the display screen.

  Further, when “switch” is touched, the display of the swing trajectory is switched to the display of “face trajectory”. By touching the display screen of this “face trajectory”, the screen is switched between “face angle at impact” and “loft angle at impact”. This screen is not a movie but a still image.

  This face trajectory display is based on the data of the triaxial acceleration and triaxial angular velocity detected at the sampling interval of 2 ms on the motion sensor 730 side, and calculates the face orientation at the interval of 2 ms on the trainer device body 710 side. It is displayed on the screen in a display mode in which the change of the surface is a set of intermittent lines. At this time, a display mode is adopted in which the center of the screen is the lowest point of the face trajectory. As shown in the drawing, 2 ms is a sampling interval for drawing the orientation of the face surface at the moment of impact, which is the lowest point. In the swing trajectory display mode as seen from the back or top, the ball is shifted to the right so that the swing trajectory can be drawn larger. In the case of the face trajectory, the orientation of the face surface before and after the impact is accurately determined. In the meaning to convey, a mode in which the lowest point (ball impact position) is displayed at the center is suitable. Note that the sampling interval may be 2 ms or less, more preferably 1 ms or less.

  Touch “Switch” in the “Face trajectory” display state to switch to the “Swing data” screen, and “Club type” “Up swing time” “Down swing time” “Face angle at impact” “Loft at impact” The screen switches to the screen that displays the "corner" as a numerical value.

  In addition to being able to confirm the face angle and loft angle numerically as “swing data”, by drawing the face trajectory at a sampling interval of 2 ms as the face trajectory, the user's own swing can be more accurately represented as an image in addition to the numerical value. It is possible to grasp.

  When “switch” is touched in the display state of “swing data”, the display returns to the moving image display state of “swing trajectory” again. Note that "save" can be executed from any display state.

  In the trainer device 710, the “swing trajectory” is repeatedly reproduced, but since the motion calculation has already been completed, the next swing can be executed to obtain the swing trajectory and the like. It has become. Therefore, the LED lamp 732 of the motion sensor 730 is in a “green continuation” state. When it is necessary to save, the user touches “Save” and then performs the next swing. If it is not necessary to save, it is possible to swing immediately after confirming “continuation of green lighting” of the LED lamp 732.

[Arc playback mode]
Next, a procedure for executing the “Arc playback mode” using the system of this embodiment will be described. The “Arc reproduction mode” is a mode for reproducing and confirming “Arc (swing trajectory, face trajectory, swing data)” stored in the trainer apparatus 710. This mode is a mode executed only by the trainer device 710. After turning on the power, as shown in FIG. 33 (A), touch “Arc playback” on the menu screen. Then, as shown in FIG. 33 (B), since the stored Arcs are displayed in the state of being arranged on the time axis in order from the newest one, the Arc to be reproduced is touched. Then, as shown in FIG. 33C, Arc is reproduced as swing trajectory, face trajectory, and swing data. Screen switching and the like are the same as in the Arc mode.

[Example display]
Next, in the “Arc mode” and the “Arc playback mode”, the function of displaying “example” in a superimposed manner when displaying “swing trajectory” will be described. When using this function, touch “Setting” on the menu screen as shown in FIG. 34A, and then open the “Arc tab” and display “Display” as shown in FIG. 34B. Touch, touch “Do not display example”, touch “Display” on the opened screen to change it to “Display example”, and then touch “Return”. By this operation, the display condition of the “swing trajectory” in the trainer device 710 is changed from the default setting “Do not display a model” to “Display a model”.

  After setting “example display” in this way, as shown in FIG. 34C, if “Arc mode” is activated by touching “Arc” from the menu screen, as shown in FIG. When the swing trajectory is displayed, the model swing trajectory is displayed in an overlapping manner. This model is based on data when a professional golfer swings using the system, and is stored in advance as “model data” in the storage device of the trainer device 710.

  Also in this “model display”, by touching the screen, you can switch the screen display from front → front (from a little above) → back → top → front →…. The configuration is displayed.

  Also, by setting to “Display Model” and confirming in “Arc Playback Mode”, as shown in FIG. 35, the wrinkles that are swung out as shown in the lower row are corrected, and training such as approaching the model as shown in the upper row is performed. Can be used.

[Setting mode]
Next, the setting mode will be described. As shown in FIG. 36A, when “Setting” is touched on the menu screen, a setting screen is displayed as shown on the right side. On the setting screen, the setting object can be switched between “swing tab”, “Arc tab”, and “system tab” by touching “feed key” and “return key”.

  An operation method for changing the display mode in the “swing mode” using the “setting mode” will be described. As shown in FIG. 36 (B), when the display position of “Head Speed” and “Estimated Flight Distance” is to be switched up and down, touch “Display Item” of “Swing Tab” to display the screen shown at the lower left corner. Let Touching “Head Speed”, which is the top display item on this screen, switches to the screen on the right side. Touching “Estimated flight distance” on the switched screen switches to a screen arranged in the order of “estimated flight distance”, “estimated flight distance”, “ball speed”, and “meet rate” as shown on the right side. Next, touch “Estimated flying distance” on the second stage, and touch “Head speed” on the switched screen. As shown on the rightmost screen, “Estimated flying distance”, “Head speed”, “Ball speed”, “Meet” “Rate” and the display position are changed. Here, by touching “Return”, the setting in which the display order is changed is stored in the trainer device 710. Thereafter, when the “swing mode” is activated, the display item can be displayed in a state where the top and bottom of the display items are switched. By switching the order of the display items in this way, it is possible to change the target of one item horizontal display by screen touch.

  Next, an operation method for changing the number of display items in the “swing mode” using the “setting mode” will be described. Touch “Setting” and “Display Item” to display a screen with a 4-item display state as shown in FIG. 36 (C), then touch “Meet Rate” and set “Do not display” on the switched screen. touch. Then, as shown on the right side, the bottom of the display item is switched to “not display”, and by touching “return” in this state, the change to the three item display is stored in the trainer device 710. After that, when the “swing mode” is activated, a screen with three items can be displayed as in the second row at the bottom. Hereinafter, similarly, two-item display and one-item display can be set.

  As shown in FIG. 37, items that can be changed for “swing tab” include “screen”, “practice mode”, “flying distance coefficient (ball)”, “flying distance coefficient (club)”, and “wedge loft angle”. There is.

  Touch “Screen” to switch between “Yes” and “No” for “Nice Shot Display”, “Nice Shot Reference Value” setting by numerical input, “Right-handed” and “Left-handed” for “Select dominant hand” Can be set. Note that the “reference value” is set to be limited to a range of “1.20 to 1.60”.

  Touching “Practice mode” allows you to set “Target setting distance upper limit”, “Target setting distance lower limit”, “Green radius” by numerical input, and “Nice on display” switching between “Yes” and “No”. It can be configured. The “target set distance upper limit” can be set to 51 to 999 yards, the “target set distance lower limit” to 50 to 149 yards, and the “green radius” to 1 to 50 yards.

  When “flying distance coefficient (ball)” is touched, a club selection screen is displayed, and after selecting a club, the flying distance coefficient can be set within a range of 50 to 150% by numerical input. . In the “flying distance coefficient (ball)”, “wedge” cannot be selected in the club.

  When the “flying distance coefficient (club)” is touched, the club selection screen is displayed, and after selecting a club, the flying distance coefficient can be set within a range of 50 to 150% by numerical input. Yes. In the “flying distance coefficient (club)”, “Putter” cannot be selected from the clubs.

  When “wedge loft angle” is touched, a wedge selection screen is displayed, and a loft angle can be set by inputting a numerical value within a range of 46 to 60 ° for the selected wedge.

  When the “Arc tab” is opened in the “setting mode”, a screen for setting “club” and “display” is displayed as shown in FIG.

  When “Club” is touched, a selection screen of “Club selection”, “Sensor position”, and “Face face calibration” is displayed. In the “Arc mode”, the club selection is possible in any of “wood”, “utility”, “iron”, “wedge”, and “putter” in “club selection”.

  The “sensor position” and “face surface calibration” are as described above. This “sensor position” and “face surface calibration” can improve the detection accuracy of the swing trajectory and the face trajectory.

  When “Display” is touched, a screen for setting switching between “Yes” and “No” for “Doll display” and “Example display” is displayed. By the combination of “display” and “not display” of “doll” and “example”, the display mode of the swing trajectory in the “Arc mode” can be changed to any of the four patterns shown in the figure.

  When “System Tab” is opened in “Setting Mode”, as shown in FIG. 39, setting items are selected from “General”, “Power Saving”, “Window Touch Correction”, “Bluetooth”, “System Information”, and “Setting Initialization”. Display the screen to select.

  When “General” is touched, “Bright”, “Normal”, and “Dark” are switched for “Screen luminance”, “m / s” and “mph” are switched for “Speed unit”, “yd” and “m” for “Distance unit”. “,” And “Date and time” can be set by numerical input.

  When “Power Save” is touched, “5 seconds” for “Auto Power Off” is selected from “5 seconds”, “10 seconds”, “30 seconds”, “1 minute”, “3 minutes”, and “OFF” for “Power Save Screen”. “10 minutes”, “20 minutes”, “30 minutes”, “60 minutes”, and “OFF”, a screen for the user to select a desired setting is displayed.

  When touching “Window touch correction”, as shown in the figure, by touching in order of “left center”, “lower center”, and “upper right corner”, position correction for “window touch” is executed, and the setting is reset. Do.

  Touch "Bluetooth" to proceed to the "New registration" setting process, touch "System information" to display the version of the program installed in the main unit, and touch "Initial setting" to "Yes" "No" A screen for inquiring is displayed, and if “Yes” is touched, initial setting is performed.

  The operation results in the above setting mode are stored in the trainer device 710 and are set for each user, and can be returned to the initial setting state by performing the initial setting.

[Measurement of head speed, etc.]
Next, arithmetic processing such as measurement of the internal structure of the microcontroller of the trainer apparatus 710, head speed, and ball speed will be described.

  As shown in FIG. 40, the first microcontroller 724 includes a 16-bit counter (timer) 724a and a memory (RAM) 724b as first storage means. The counter 724a receives a 2.5 MHz signal as a reference pulse and performs counting. The value of the counter 724a can be taken into the capture register 724c when a predetermined event occurs. A periodic data storage area for storing periodic data is provided in the memory 724b, and this area consists of 110 array areas (total of 220 bytes) with a 16-bit width.

  The first microcontroller 724 receives the Doppler pulse output from the comparator 723. The first microcontroller 724 measures the period of this Doppler pulse. A counter 724a is used to measure this period. Specifically, when a fall of the Doppler pulse occurs as a predetermined event, a fall detection interrupt of the Doppler pulse is generated and the counter value at that time is set to be captured in the capture register 724c. The capture register 724c stores accumulation candidate data. When a Doppler pulse falling detection interrupt occurs, the contents of the capture register 724c are recorded in the memory 724b as periodic data in an interrupt processing routine.

  When the counter value overflows in the counter 724a, a counter overflow interrupt is generated. When a counter overflow interrupt occurs, counter overflow interrupt processing is performed.

  In each process executed by the first microcontroller 724, “waiting to start”, “measuring”, “completed”, and “error” are defined as measurement states (process states), and the respective states are stored in the memory 724b. The data is stored in the set state storage area, and the processing content is changed based on the stored state. The state “wait for start” is a state waiting for the fall of the first Doppler pulse. This state is set immediately after resetting (immediately after power-on), and the fall of the Doppler pulse is detected, and when the cycle is equal to or less than the specified value, the state is changed to “measuring”. The state “measuring” is a state in which periodic data is accumulated. The state “completed” is a state in which the accumulation of the periodic data is completed and the number of valid measurement data exceeds the specified value. When this state is reached, a speed calculation process is performed to check the accumulated data and calculate the speed. The state “error” is a state in which the accumulation of the periodic data is completed, but the number of accumulated data is less than the standard. When this state is reached, the accumulated data is immediately discarded, and a process (not shown) for returning to the “waiting for start” state is performed.

  First, the counter overflow interrupt processing function executed by the first microcontroller 724 will be described with reference to the flowchart of FIG. Since the counter 724a has 16 bits, when the counter value reaches 65535 + 1, a counter overflow interrupt is generated and this processing is started.

  First, in S110 (S110 is an abbreviation for step 110, and the same applies hereinafter), the number of overflow occurrences held in the memory is incremented by one. In subsequent S120, it is determined whether the measurement state is “waiting to start”, “complete”, or “measuring”. If the measurement state is “wait for start” or “complete” (S120: wait for start or completion), this process is terminated. On the other hand, when the measurement state is “measuring” (S120: during measurement), the process proceeds to S130. In S130, it is determined whether or not the number of overflow occurrences has reached a specified number. This specified number of times is set to 16. The fact that the overflow occurs 16 times means that the falling edge of the pulse is not input for a long time of about 400 ms. In such a case, it is necessary to exit the “under measurement” state. . If the number of overflow occurrences has not reached the prescribed number (S130: No), the counter overflow interrupt process is terminated. On the other hand, when the number of overflow occurrences reaches the specified number (S130: Yes), the process proceeds to S140. In S140, it is determined whether or not the number of recorded data (the number of recorded periodic data) exceeds a specified number. This specified number is set to “32”. If the number of recorded data exceeds the specified number (S140: Yes), the process proceeds to S150, the measurement state is changed to “completed” in S150, and this interrupt process is terminated. On the other hand, if the number of recorded data does not exceed the prescribed number (S140: No), the process proceeds to S160, the measurement state is changed to “error” in S160, and this interrupt process is terminated.

  By such processing, when an overflow occurs, the number of overflow occurrences is counted, and when an abnormal state such as an overflow occurrence number of 16 occurs, the measurement is stopped there and the recorded data exceeds the specified number Changes the measurement state to “complete” and performs the speed calculation process described later, whereas if the recorded data does not exceed the specified number, the measurement state is changed to “error” and the accumulated data is discarded. Then, a process (not shown) for returning to the “waiting for start” state is performed.

  Next, the contents of the Doppler pulse falling interrupt processing (Doppler pulse period measurement and accumulation processing) when a Doppler pulse falling interrupt occurs will be described with reference to FIGS. 42 and 43. FIG.

  When detecting the fall of the Doppler pulse, the first microcontroller 724 starts the Doppler pulse fall interrupt processing shown in FIGS. First, in S310, it is determined whether the measurement state is “waiting to start”, “completed”, or “under measurement”. If “waiting for start” (S310: wait for start), the process proceeds to S320, if “completed” (S310: completed), the process proceeds to S440, and if “measuring”, the process proceeds to S360.

  In S320, it is determined whether or not the cycle is smaller than a specified value. As the specified value, for example, the head speed of the golf head is set to 776 times which is a count value corresponding to about 0.31 ms which is a cycle corresponding to 20 m / s. Specifically, it is determined whether or not the value of the capture register 724c is smaller than the specified value. When the cycle is smaller than the specified value (when the count value is smaller than 776 times) (S320: Yes), the process proceeds to S330, and when the cycle is the specified value or more (when the count value is 776 times or more) ( (S320: No), the process proceeds to S440. In S330, it is determined whether or not the number of overflow occurrences is zero. When it is 0 (S330: Yes), the process proceeds to S332, and when it is not 0 (non-zero) (S330: No), the process proceeds to S440.

  In S332, C is incremented by “+1”, and in S334, it is determined whether or not the incremented new C value is 4. When the value of C is not 4, that is, from 1 to 3 (S334: No), the process proceeds to S440. When the value of C is 4, after resetting to C = 0 (S336), the process proceeds to S338. In S338, the first microcontroller 724 outputs an accumulation start signal to the second microcontroller 725. In other words, when the cycle is smaller than the measured value (S320 is Yes) and no overflow has occurred (S330 is Yes), it can be determined that a swing has occurred, and the accumulation start signal is Is output. The function of executing the processing steps of S320 to S338 constitutes a swing determination unit.

  This swing discrimination means discriminates that there is a head swing when the period of the Doppler signal based on the Doppler signal output by the Doppler sensor is a periodic pattern corresponding to the head swing (finally Yes in S334). doing. A periodic pattern corresponding to the head swing is determined in advance based on a periodic pattern obtained by swinging various clubs with a large number of people in advance and a periodic pattern obtained when the club is not swinging. For example, a periodic pattern corresponding to a user's swing may be learned and used.

  After outputting the accumulation start signal, the first microcontroller 724 proceeds to S340. In S340, the measurement state is changed to “under measurement”, and the process proceeds to S350. In S350, the number of falling occurrences stored in the memory 724b is changed to zero. In this manner, when the period of the Doppler signal output by the Doppler sensor 721 becomes smaller than a predetermined value, setting is made to start accumulation of period data in the memory 724b. Therefore, in the interrupt process at the next falling edge of the Doppler pulse, it is determined as “measuring” in S310, and the processes after S360 are performed.

  In S360, the number of occurrences of falling stored in the memory is incremented by one. In subsequent S370, it is determined whether or not the number of overflow occurrences is zero. If the number of overflow occurrences is 0 (S370: Yes), the process proceeds to S400, and if the number of overflow occurrences is not 0 (S370: No), the process proceeds to S380.

  Since the counter 21 is 16 bits, an overflow interrupt occurs when the count value exceeds 65535, and the overflow occurrence count is incremented in the overflow interrupt process (S110). The count value 65535 corresponds to about 26 ms, and is sufficiently longer than the value (period) to be measured. Therefore, if overflow occurs, it is determined that the period data need not be recorded.

  In S380, it is determined whether or not the cycle is smaller than a specified value. Specifically, it is determined whether or not the value of the capture register 21a is smaller than this specified value. This specified value is set to 776 times the same as the specified value in S320. When the cycle is smaller than the specified value (when the count value is smaller than 776 times) (S380: Yes), the process proceeds to S390, and when the cycle is greater than the specified value (when the count value is 776 times or more) ( (S380: No), the process proceeds to S400. In S390, the data is recorded in the memory 724b. That is, the value of the capture register 724c is stored in the array on the memory (RAM) 724b (if there is data recorded previously, it is recorded in the area next to the area stored in the previously stored array), and the process proceeds to S400.

  In S400, it is determined whether or not the number of falling occurrences during measurement has reached a specified number. If the specified number has been reached (S400: Yes), the process proceeds to S410, and if the specified number has not been reached. (S400: No), the process proceeds to S440. The specified number of times (corresponding to “wave number”) is set to 110 times. The 110 times corresponds to 6 mm × 110 times = 66 cm as a “distance from when the measurement object enters the detection range of the Doppler sensor to the measurement object position”.

  In S410, it is determined whether or not the number of recorded data in the array on the memory 22 exceeds the prescribed number (S410: Yes), the process proceeds to S420, and in S420. Then, the measurement state is changed to “completed”, and the interruption process is terminated. On the other hand, if the specified number has not been exceeded (S410: No), the process proceeds to S430, and in S430, the measurement state is changed to “error” and the interrupt process is terminated. The specified number of recorded data in S410 is set to “32”. That is, when it is determined that an overflow has occurred in the process of S370 (S370: Yes) or when the period is determined to be equal to or greater than the specified value in S380 (S380: No), the process of S390 is not performed and the period data Therefore, the number of recorded data may be less than 110. In this case, the number required for the speed calculation process of FIG. 9 described later is set to 32, and when this number is exceeded (S410: Yes), the measurement state is set to “completed” and the speed calculation process is performed. If the number is not exceeded (S410: No), the measurement state is changed to “error”, the accumulated data is discarded, and the process returns to the “waiting for start” state. I will let you.

  When the measurement state is “completed” by the Doppler pulse falling detection interrupt processing as described above, 33 or more pieces of data related to the period for which the speed is to be calculated are accumulated in the memory (array) 724b. .

  Next, the speed calculation process will be described with reference to FIG. The speed calculation process starts when the measurement state becomes “complete”.

  In S510, the moving average of data from the beginning to the number of accumulated data among the periodic data accumulated in the memory 724b is calculated, and the calculation result is stored in the memory (RAM) 724b. Specifically, an arithmetic average is obtained from four data of the period data 1 to the period data 4 and stored in a moving average storage array in the memory (RAM) 724b. Subsequently, an arithmetic average is obtained from the four data of the period data 2 to the period data 5, and is stored as the moving average period data in the moving average storage array in the memory 724b. Similarly, the arithmetic average of the periodic data is obtained and sequentially stored in the moving average storage array in the RAM.

  Next, data with large variation is excluded. That is, if all of the four original data used for the calculation of the moving average in S510 are not within the range of the average value ± n%, the data is data with a large variation (that is, data with low reliability of the measurement value). ) And the moving average value calculated from the original data is excluded from the subsequent processing.

  Specifically, in step S520, the value of n is first set to 12.5%, and when all of the four original data are not within the range of the average value ± 12.5%, the data is regarded as data having a large variation. Therefore, an exclusion flag is set for the moving average value calculated from the original data. For example, the exclusion flag allocates a 1-bit memory area for one moving average period data in a format corresponding to the moving average storage array.

  In the subsequent S530, if the number of data (the number of valid data) for which the exclusion flag is not set is less than 10 as a result of the exclusion process in S520 (S530: Yes), the exclusion flag is canceled, and the process proceeds to S540. .

  In S540, if the value of n is now 25% and all of the four original data are not within the range of the average value ± 25%, the data is regarded as data having a large variation and is calculated from the original data. An exclusion flag is set for the moved average value.

  In the subsequent S550, it is determined whether or not the number of data (the number of valid data) for which the exclusion flag has not been set is less than 10 as a result of the exclusion process in S520. Transition. In S560, the measurement state is set to “error”, and this process ends. On the other hand, when the number of data (number of valid data) for which the exclusion flag is not set is 10 or more (S550: No), the process proceeds to S570. In S530, when the number of data (the number of valid data) for which the exclusion flag is not set is 10 or more (S550: No), the process proceeds to S570.

In S570, the minimum cycle data (minimum cycle value = maximum frequency value = corresponding to the maximum speed) is searched from the moving average cycle data in which the exclusion flag is not set. In the subsequent S580, the speed (head speed) is calculated from the minimum cycle data obtained in S570. The speed is calculated based on (Equation 1) below.


(V: head speed, c: speed of light (299792485m / s), fb: counter reference pulse frequency, f0: microwave Doppler sensor output frequency (24.15GHz), nmin: value of minimum cycle data)

  In subsequent S590, the head speed obtained in S580 is displayed on the display. For example, it is displayed as 50.0 m / s. At this time, the display of the head speed blinks for 10 seconds from the start of the display. When the flashing display process for 10 seconds is completed, the head speed obtained in S580 is displayed as a lighting display, and the process proceeds to S600.

  In the subsequent S600, the measurement state is changed to “wait for start”.

  With such a configuration, the user can know the head speed by looking at the display. That is, the golfer who is a user sets the trainer device 710 at a predetermined position and operates the switch group to turn on the power. Next, in this state, the golfer swings the golf club. At this time, the ball may be actually hit by teeing up, or may be shaken without setting the ball.

  When the golf club head enters the detection range of the Doppler sensor 721 along with the swing, a Doppler pulse having a period corresponding to the moving speed of the head 2 is input to the first microcontroller 724, and based on this, data of each period is stored in the memory. It is stored in 724b and then the maximum speed is measured. When the measurement is performed correctly, the calculated head speed (instantaneous maximum speed) is displayed on the display screen 711 in a blinking state. On the other hand, if the measurement cannot be performed correctly for some reason, the speed is not displayed. Therefore, the user can know whether or not the measurement is possible and whether or not the speed can be measured based on whether or not the speed is displayed in a blinking state by looking at the display screen 711 after the swing.

  Next, the function of the second microcontroller 725 will be described. When the second microcontroller 725 receives the accumulation start signal from the first microcontroller 724 in accordance with the execution of S338 described above, the second microcontroller 725 incorporates the Doppler signal (amplified signal) output from the amplifier 722 into the second microcontroller 725. Is converted into a digital signal by the A / D converter, and is loaded and stored in a built-in memory (RAM) for 160 ms. When the capture is completed, the speed is calculated by performing an FFT operation on the accumulated data in the memory. As a method for calculating the speed by performing an operation by FFT, a known method used for a speed gun or the like may be used. Then, the calculated speed data is sent to the first microcontroller 724.

  In other words, the moving speed of the head accompanying the swing of the golf club gradually increases from the start of the swing, reaches the maximum speed before and after hitting the ball, and then gradually decreases. On the other hand, since the ball remains stopped at the beginning of the swing of the golf club, the moving speed becomes 0, and when the head hits and strikes, the moving speed increases. There is a difference between the peak of the speed change of the head speed and the peak of the speed change of the ball speed (the peak of the ball speed occurs with a delay). Therefore, the swing determination means (the processing algorithm that executes S320 to S328) detects the golf swing and the first microcontroller 724 outputs the accumulation start signal, and then the second microcontroller 725 determines the ball speed. A Doppler signal (signal amplified by the amplifier 722) necessary for calculation is recorded.

  Accordingly, the head speed is calculated based on a data group in which data related to the period of the Doppler signal based on the Doppler signal output by the Doppler sensor is calculated, while the ball speed is calculated based on the Doppler signal output from the Doppler sensor. Calculation is performed based on the A / D conversion data group in which the / D conversion data is accumulated. By separating the head speed and the ball speed in this way, both the head speed and the ball speed can be accurately measured.

  Further, when speed data is sent from the second microcontroller 725, the first microcontroller 724 displays the speed as a ball speed on the display screen 711 and divides the ball speed by the head speed calculated by itself. The obtained value is displayed on the display screen 711 as a meet rate.

  That is, the first microcontroller 724 calculates the meet rate by “meet rate = ball speed / head speed”.

  The estimated flying distance is obtained from the ball speed and the used club type when the ball is actually hit, and in the case of swinging, the flying distance is obtained from the head speed and the used club type. Specifically, a coefficient for the ball speed and a coefficient for the bed speed are set in advance for each club type (a table of club type-coefficients is provided), and a coefficient corresponding to the club type is set for the ball speed or the head speed. The value multiplied is taken as the estimated flight distance. The presence / absence of the ball may be designated manually by manual operation, or various sensors may be provided and automatically recognized by the apparatus.

  In this embodiment, the speed is calculated based on the data for each period, the data that may be erroneously detected is discarded, and the speed is determined based on the remaining reliable data finally. Therefore, the displayed speed is accurate without being affected by the surrounding conditions. In addition, when the head speed is measured in a state where the ball is actually hit, since the ball jumps out vigorously after impact, the moving speed of the ball is sufficiently higher than the head speed, and the output of the Doppler sensor 721 is The wave number of the Doppler signal generated during the distance from the point where the golf club head enters the detection range of the Doppler sensor 721 to the position where it is assumed to impact the ball may be based on the movement of the ball. Since the period data is stored in the memory 724b only for the specified number of times corresponding to 110 times, the swing speed can be correctly measured regardless of the presence or absence of the ball.

  As described above, the “head speed”, “ball speed”, “estimated flight distance”, and “meet rate” calculated by the trainer device 710 based on the detection signal of the Doppler sensor 721 are the data in the “swing mode” and “practice mode”. In addition to being used for display, the “meet ratio” is compared with the set “meet ratio reference value (initial setting: 1.40)”, and “nice shot animation” in “swing mode” is displayed. “Estimated flight distance” is reflected in whether “Nice-on animation” is displayed by comparing with “Target setting distance” and “Green radius” set in “Practice mode”. Is done.

  Note that the arithmetic processing in the trainer device 710 is also executed in the “Arc mode”. Accordingly, after confirming the screen of the swing trajectory or the like in the “Arc mode”, returning to the menu screen and touching “Swing” makes it possible to refer to the “head speed” or the like in the current swing. In the “Arc mode”, the “model display” can be displayed. As a result, the swing path is corrected to match the swing path of the “model”, and the “head speed” at that time is confirmed in the “swing mode” display. This is useful for training to increase the flight distance through a compact swing. Note that the swing trajectory measurement in the “Arc mode” includes the measured values of the triaxial velocity and the triaxial angular velocity transmitted from the motion sensor 730 at intervals of 2 ms, the sensor mounting position and the calibration result of the face surface in the setting mode. Is calculated based on the result recorded by the first microcontroller 724 of the trainer device 710 as position information for each predetermined time and the detection result of the impact timing. With the calibration function in the setting mode, the swing trajectory, face trajectory, upswing time, downswing time, face angle at impact, and loft angle at impact can be accurately calculated.

  In addition, when “swing mode” is executed when the motion sensor 730 is attached to the club and the power is turned on and the LED lamp 732 is continuously lit in green, the “head speed” for the current swing is checked. After that, if the user returns to the menu screen and touches “Arc”, the swing trajectory, face trajectory, and swing data in the current swing can be confirmed.

  This is the same when an operation for switching the display screen between the “practice mode” and the “Arc mode” is performed.

  As described above, according to the present embodiment, the “head speed” and “ball speed” can be accurately measured by the Doppler sensor, and the “estimated flight distance” can be accurately calculated based on the measurement. In addition to being able to detect the “rate” accurately, the “swing trajectory”, “face trajectory”, and “swing data” at the time of the swing can be accurately measured by performing the first calibration or the like. Furthermore, by using the “example display”, the user can accurately and accurately give information to be referred to when training so that a more accurate swing can be executed at a more appropriate head speed.

  In this embodiment, “head speed” and “ball speed” are measured, “estimated flight distance” and “meet ratio” are calculated, “swing trajectory”, “face trajectory” and “swing data” are calculated, and the motion sensor 730 is notified. Various calculation processes such as detection of switch operations such as screen switching by touching the display screen, switching of the display screen, and switching of the display screen are performed by a computer program previously installed in the ROM of the microcontrollers 724 and 725 of the trainer apparatus main body 710. It has been realized. The computer program itself may be uploaded to a server or the like as a downloadable application, downloaded to and installed in the trainer apparatus main body 710 using the Bluetooth wireless communication function, or installed in various types of terminal devices or personal computers. It does not matter as a configuration used.

  Further, the first microcontroller 724 and the second microcontroller 725 of the trainer apparatus main body 710 in the present embodiment may be configured by one controller. Conversely, a speed detection device provided with the microwave Doppler sensor 721 and a separate third processing unit (for example, a mobile communication terminal) are provided, and the motion sensor 730 is attached to the golf club as in this embodiment, and the speed is The detection device is installed under the same installation conditions as the trainer device 710 in the present embodiment, the detection data is transmitted from the speed detection device and the motion sensor 730 to the mobile communication terminal, and the first microcontroller in the mobile terminal device It can also be configured as a system that performs the same arithmetic processing as in the 724 and the second microcontroller 725. In this case, the detection data of the motion sensor 730 may be received by the mobile terminal device via the speed detection device, or the calculation is performed in the speed detection device, and the calculation result is transmitted to the mobile terminal device. As an internal process of the mobile terminal device, a menu screen may be displayed, a display screen may be switched, or a setting change process may be performed.

  According to each embodiment described above, the object is generated by the tensile force generated in the fastener (rubber band 20, rubber rings 120, 220, mounting belt 750) on the rod-like portion (shaft 3a) of the object (golf club 3). The attachment work at the time of attaching (golf swing sensor 1,101,201,301,401,501,601, motion sensor 730) can be made easy.

  As mentioned above, although the Example for implementing this invention was described, this invention is not limited to these, The various change in the range which does not deviate from the summary is possible.

  For example, the mounting structure may be employed when a sensor is mounted on a tennis racket shaft, baseball bat, throwing spear, bicycle frame, automobile engine propeller shaft, connecting rod, or the like. Moreover, it can also be set as the attachment structure at the time of attaching objects other than a sensor, and can also be applied to the attachment structure in the case of attaching the sensor holder for attaching a sensor.

  At the time of attachment, an anti-slip sheet may be interposed between the rubber contact portion 20 and the shaft 3a and between the rubber band 20 and the shaft 3a.

  As the fastener, a perforated rubber band, a rubber string provided with a ring, or the like may be adopted, and the material may be a synthetic resin other than rubber or a coil spring.

  A hook-shaped pin may be employed as a holding hook that is to be prevented from coming off, or a slit formed so as to be cut from the front side of the housing. In the type of the third embodiment, the temporary hook portion may be formed with a hook-shaped pin instead of a hook. For example, only the upper portion is a temporary hook portion with an upward claw, and the lower side is directed forward as in the first embodiment. You may comprise so that the nail | claw which was used may be provided.

  In the type of the first embodiment, the number of openings may be 4 or more, or vice versa.

  In the type of the second embodiment, a sliding type assist means may be provided instead of a rotary type so as to reduce the force in the work of extending the fastener from the temporary hook to the main hook, or a large object is attached. In such a case, these levers and sliders may be electrically operated rather than manually operated.

  Further, in Example 1, the battery housing structure of Example 4 may be adopted, or a structure in which the terminal cover is attached to the shaft side as in Example 5 may be adopted.

  As shown in FIGS. 45A and 45B, a mounting belt 750 may be used for the golf swing sensor 1 of the first embodiment that does not include a sponge body. Also at this time, as shown in the figure (A), not only is it used for the part that is hooked to the hook part of the sensor body during normal use, but in the state shown in the figure (A), the fixing to the shaft is weak and the sensor body moves. In this case, as shown in the figure (B), the length of the rubber band used for tightening is shortened by hooking this part on the hook part of the sensor body, and the sensor body is fixed to the shaft with a stronger force. Therefore, the sensor body becomes difficult to move. In this case, in the mounting belt 750, as described above, by making a plurality of places where the hook portion is hooked, two types of fixing methods can be performed with one type of rubber band (more if the number of hooking points is increased). Costs are lower than attaching different types of rubber bands. Also, the method of changing the place to be hooked by one rubber band is simpler and easier to understand than the selection from a plurality of rubber bands having similar shapes and different lengths. In the method shown in FIG. 2B, a large force is required to hook the rubber band on the hook portion on the opposite side. If you want to fix the sensor body weaker than fixing it by the method shown in the figure (B) and stronger than fixing it by the method shown in the figure (A), as shown in FIG. ) Is fitted on the shaft, and the sensor body is stopped from above, so that the amount of the rubber band to be stretched increases, so that it can be fixed with an intermediate force between (A) and (B). In this case, the fixing force can be changed by changing the thickness of the rubber tube 800. The rubber tube 800 has a cut 801, and the cut 801 may be opened and attached to the shaft 3a.

  Here, in the modified example of FIG. 45C, the rubber tube 800 is assumed to have an inner diameter of 12 mm or less, and has a dimension that allows the cut 801 to be opened when the rubber tube 800 is attached to the shaft 3a of the golf club. Is desirable. The material of the rubber tube 800 may be either synthetic rubber or silicone rubber, but the silicone rubber is superior in terms of adhesion and friction performance, and the material color is black. Is superior to silicone rubber, which is based on white. The thickness of the rubber tube 800 may be about 3 mm.

  Further, in the attachment belt 750 of the eighth embodiment, an attachment method in which the second intermediate partition portion 752n is hooked on the hooks 12a to 12c and further tightened may be performed as necessary.

  Further, the golf swing trainer system 700 according to the eighth embodiment may be combined with a sensor of the type described in the first to seventh embodiments other than the type using the attachment belt 750 described in the eighth embodiment.

In Example 8, a silicon gel sheet may be attached to the entire surface of the sponge body 737 located on the golf club side with a double-sided tape. The surface of the silicon gel sheet is less slippery than the sponge body 737 and can be fixed without slipping when the club is swung.
The total thickness of the silicon gel sheet and the double-sided tape is 0.25 mm, and the silicon gel sheet is significantly thinner than 5 mm which is the thickness of the sponge body. This is because when the silicon gel sheet is compressed, the repulsive force is weaker than that of the sponge body 737, for example, the pressed portion remains compressed, and the surface of the silicon gel sheet becomes uneven, for example, and the adhesiveness decreases. Because it ends up.
As described above, the surface of the golf club that is in contact with the shaft side is provided with a first member (silicon gel sheet in the above example) that is relatively thin and has a small repulsive force and is thin. A structure provided with a second member (sponge body 737 in the above example) that is thicker than the one member on the side away from the shaft and is made of a material having a relatively strong surface repulsion and a relatively strong repulsive force. It is good to do.

  The present invention can be used in various industries as a structure for attaching an object to a rod-like portion of an object. Moreover, it can utilize as practice systems, such as golf.
