Description

The present invention relates to a system or the like.

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

In the swing sensor described in Non-Patent Document 1, a fixture separate from the sensor body is attached to the shaft of the golf club in advance, and the sensor body is slid in the axial direction using a dovetail joint. It has a mounting structure that allows you to attach and detach. In this mounting structure, sufficient play is formed in the dovetail joint in order to facilitate attachment / detachment of the sensor body. Therefore, a thick and strong rubber band is used to attach the attachment so that the attachment does not loosen even if the centrifugal force due to the swing of the golf club is applied to the sensor body.

Golf Classic March 2013 issue (pages 86-91)

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 to obtain a swing trajectory or the like. It is for analysis.

Taking golf practice as an example, it is important to catch the ball with an accurate head speed, an accurate swing trajectory, an accurate face trajectory, and an accurate loft angle. However, in the technology of Non-Patent Document 1, the sensor mounting position is used. There was a problem that the trainer function was not sufficient because it could only be a rough estimation calculation using acceleration data and the like.

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

The system of the present invention made to achieve the above object is (A) a process for acquiring data necessary for specifying a swing trajectory and speed, and calculating and notifying information on the swing trajectory and speed. It is characterized in that it is provided with arithmetic processing means to perform, and is configured to acquire each of the data separately by different detection means.

According to the system of the present invention, the data necessary for specifying the swing trajectory and the data necessary for specifying the swing speed are separately acquired by different detection means, and the arithmetic processing means is based on these data. Performs processing to calculate and notify information about the trajectory and velocity of. As a result, the information is highly accurate and calculated based on the measured values. For example, in the conventional configuration in which the speed is obtained 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, the information on the speed is not merely an estimation. It can also be configured.

Further, in the system of the present invention, (B) the arithmetic processing means acquires data corresponding to the same swing from each of the detection means, and the trajectory and speed of each swing in which the swing is swung once. It is also preferable to have a configuration that it is configured as a means for calculating information about.

Information on the trajectory and speed of the swing when an object is swung once can be calculated accurately, and by performing notification based on the calculation result, once from both the viewpoint of the trajectory and the viewpoint of speed. It is possible to give the user an opportunity to analyze and examine the swing of. The "thing" to be swung may be, for example, a part of a machine or a part of the body of a human or an animal, and is particularly preferable as a tool. As the equipment, it is preferable to use equipment that a person swings using his / her body, and in particular, it is preferable to use sports equipment.

In these systems of the present invention, (C) the detecting means for acquiring the data necessary for specifying the trajectory of the swing is attached to the swing, and the detecting means for acquiring the data necessary for specifying the speed of the swing is. It is also advisable to adopt a configuration in which it is installed in a place other than the above.

By attaching a detection means that acquires the data necessary for identifying the swing trajectory to the object, the swing trajectory of the object can be directly detected, and the detection means that acquires the data necessary for identifying the swing speed. By installing it in another appropriate place other than the above, the speed at which an object moves can be objectively and accurately grasped from the outside, and as a result, the trajectory and speed of the swing can be detected accurately. In particular, the "other appropriate place" may be, for example, a place that does not move at least with a swing, and preferably a place that does not move constantly.

In this case, it is preferable to further include at least one of the following configurations (D) and (E). (D) The arithmetic processing means controls to determine and notify whether or not the said thing is in a state where it has finished holding for the start of a swing based on the acquired data.
(E) The arithmetic processing means controls to determine and notify whether or not the said thing is in a state where it has finished swinging, based on the acquired data.

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

In these cases, it may be further provided that (F) the notification is performed from the portion attached to the swinging object.

By displaying based on the notification by the swing detecting means that has received the above notification, it is possible to accurately inform the user who is trying to swing the object whether or not the swing may be started, which is wasteful. It is possible to perform no measurement. As a result, the accuracy of detection is also improved.

Further, in these systems of the present invention, (G) the arithmetic processing means can make the display means distinguish the overlap of the trajectories from the start of the swing to the end of the swing as the processing for the notification. It is also preferable to include a configuration in which information regarding the trajectory of the swing is displayed in the display mode.

For example, in the case of golf swing practice, one swing is composed of an upswing and a downswing of a club, and the trajectories overlap. In such a case, by using a display mode that can distinguish the overlap, the user can accurately judge 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 follows (G1) to (G3).
(G1) As the display mode, the arithmetic processing means performs a process of gradually or stepwise changing the display color of the trajectory from the start of the swing to the end of the swing.
(G2) As the display mode, the arithmetic processing means performs a process of changing the display color at the extreme point of the trajectory from the start of the swing to the end of the swing.
(G3) As the display mode, the arithmetic processing means performs a process of displaying a trajectory from the start of the swing to the end of the swing as a moving image.

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 by the difference in color in the overlapping portion in the state where the entire swing trajectory is displayed. According to the configuration of (G3), for example, the upswing and the downswing of golf can be distinguished by displaying the swing trajectory as a moving image. The configuration of (G3) may be adopted together with the configurations of (G1) and (G2). In this case, it is possible to distinguish the overlap from the entire orbit that has been drawn while feeling the change of the orbit during the reproduction of the moving image, and it is possible to convey the information to the user in a form that is easier to understand.

A system provided with display means may further employ either or both of (H) and (I).
(H) When the arithmetic processing means displays information on the swing trajectory to the display means, the display is such that the ball before being hit by the display means is shifted in a predetermined direction with respect to the center of the screen. Perform the process of displaying in the mode.
(I) When the arithmetic processing means displays information on the swing trajectory to the display means, the ball before being hit by the object and the standing position of the person swinging the object are located in the center of the screen. On the other hand, the process of displaying in a display mode distributed in a predetermined direction is performed.

By adopting such a configuration, it is possible to make a display such as drawing a swing trajectory by effectively utilizing the width of the screen of the display means. For example, in the case of golf swing practice, when the ball is displayed in the center of the screen, the swing trajectory becomes a small display as a whole and it is easy to win. This is because the swing trajectory can be drawn large.

In the system provided with the display means, (J) the data necessary for specifying the swing trajectory is acquired at a sampling interval of 2 ms or less, and (K) the arithmetic processing means is used on the display means. On the other hand, it is also preferable to adopt a configuration in which the orbit is displayed in a display mode indicating a continuous change in the position corresponding to the sampling interval.

For example, in the case of golf swing practice, the lowest point of the swing trajectory is the position where the ball is met. In this case, when the sampling interval from the swing detecting means is about 5 ms, the lowest point position cannot be accurately captured, whereas the detection signal from the swing detecting means is set at a sampling interval of 2 ms or less, more preferably 1 ms or less. This is because the accuracy of grasping the lowest point position is improved by acquiring, and it becomes possible to more accurately convey the trajectory of the swing at the moment of impact 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 this case as well, since the configuration for calculating the estimated flight distance using the detection result by the Doppler sensor is adopted, the calculation accuracy of the estimated flight distance is improved, and more accurate trainer information can be given to the user.

In this case, (62) it is preferable that the arithmetic processing means includes a nice-on determination reference value automatic setting means for automatically setting the nice-on determination reference value based on the selected club.

This is because the trouble of setting the judgment standard is eliminated.

When the practice mode is provided, (63) the arithmetic processing means may also adopt a configuration in which the nice-on determination reference value manual setting means for manually setting the nice-on determination reference value associated with the club is provided. ..

This is because it is possible to change the standard according to the skill level and each club that is good or bad, and it is expected to have the effect of improving the motivation of practice and improving the result.

When these practice modes are provided, (64) the arithmetic processing means may also adopt a configuration in which the nice-on non-notification switching means for switching to a setting in which the Nion notification by the nice-on notification means is not performed.

Suitable when nice-on notification is troublesome.

Here, in the mounting structure described in Non-Patent Document 1, although the sensor body can be easily attached and detached, it is necessary to mount the mounting tool so as to tighten the shaft of the golf club with a thick and strong rubber band. There is a problem that it requires force to attach the.

Therefore, if the purpose is to facilitate the attachment work when attaching an object to the rod-shaped portion of the object by the tensile force generated by the fastener, the following inventions should be extracted from the following examples. 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 hung on the back surface side of the object body. (1A) The fastener is in a state in which one end side is prevented from coming off by the object body, and the hanging ring portion on the other end side is stretched by the rod-shaped portion when hooked on the hooking portion of the object body. (1B) At least one of the hooking portion and the fastener is provided with a stretching force reducing structure for reducing the fastener stretching force required when hooking the hooking ring portion on the hooking portion. It is characterized by that.

By doing so, it is possible to facilitate the attachment work when attaching the object to the rod-shaped portion of the object by the pulling force generated in the fastener. For example, the fastener is easy to turn the back of the rod-shaped portion, and when the fastener is pulled by turning the back of the rod-shaped portion, the object is less likely to shift with respect to the rod-shaped portion, and the hanging ring portion is clamped on the object body side. The work of hooking on the part can be easily done.

In the "configuration in which the rod-shaped portion of the object is sandwiched between the object body and the fastener", the form is not limited to the form in which the object body and the fastener are in direct contact with the rod-shaped portion, but between the object body and the rod-shaped portion. A form may be adopted in which some inclusions such as a non-slip sheet are sandwiched, or a form in which some inclusions are sandwiched between the fastener and the rod-shaped portion may be adopted, or an object. It is also possible to adopt a form in which inclusions are sandwiched between both the main body and the fastener.

The "state in which the fastener is stretched by the rod-shaped portion" is based on the relationship between the thickness and diameter of the rod-shaped portion of the object sandwiched between the clamp and the object body and the length from one end side to the other end side of the fastener. It means a state caused by a relationship in which a pulling force is generated on the fastener when the fastener is turned on the back side of the rod-shaped portion and hooked on the hooking portion of the object body.

The "object" and "rod-shaped part" include, for example, a golf club shaft, a tennis racket shaft, a baseball bat, a spear for throwing, a bicycle frame, a propeller shaft of an automobile engine, a conrod, and the like. be able to.

Examples of the "clamp having a hanging ring portion" include a rubber ring, a rubber band with a hole, and a rubber cord having a ring. The material is not limited to rubber, but may be synthetic resin, coil spring, or the like.

Examples of the "hooking portion" include hook-shaped hooks, mushroom-shaped pins, and the like that are provided so as to abut from the object body, and slits that are formed so as to cut into the object body from the front side. can.

In addition, examples of the "stretching force reducing structure that can be provided for the fastener" include reducing the wire diameter in the rubber ring and increasing the number of holes in the perforated rubber band.

Furthermore, as a "stretching force reducing structure that can be provided for the hooking tool", a temporary hooking claw that protrudes in a direction other than the stretching direction of the fastener is provided, or the hooking part rotates from the rear to the front. It can be equipped with a lever or slider that can be slid or slid as a temporary hook. In this case, the lever or slider may be manually operated or may be electrically operated.

Further, as a "stretching force reducing structure that can be provided on both the fastener and the hooking portion", for example, the number of hooks is increased, and the number of holes of the perforated rubber band is increased accordingly to the rubber band rubber. It is possible to reduce the area of the cross section that supports the tensile force of the rubber.

Here, the configuration (1B) may be as follows.
(2) As the stretching force reducing structure, the hooking portion is provided with a temporary hooking portion for temporarily hooking the hanging ring portion.

By providing the configuration (2), it is sufficient to pull the fastener to the extent that the fastener is temporarily hooked on the temporary hooking portion when the object is attached, and the stretching force when the fastener is hooked can be reliably reduced. The work of stretching the fastener after the temporary hooking is performed can be easily performed because the temporarily hooked portion can be used as a fulcrum.

For example, it is advisable to "set the relationship between the temporary hanging portion and the main hanging portion so that the temporary hanging state has a smaller stretching force than the main hanging state". In this case, "the temporary hanging part has a structure in which the temporary hanging part is pulled and hung in a direction different from the direction in which the force is applied to the main hanging part", or "the temporary hanging part is in the position where the main hanging part is in the main hanging state". It can be placed at a position in front of the pulling direction, or it can be set as "the main hooked state is a state of being hooked on a plurality of parts, and the temporary hooked state is a state of being hooked on one part".

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

Here, the direction of the pulling force that should be generated in the fastener in order to sandwich the rod-shaped portion of the object between the object body and the object body is the direction in which the fastener is routed. By providing the configuration (3), the fastener is provided in a direction other than the direction in which the fastener should generate a pulling force for sandwiching the rod-shaped portion between the object body and the fastener when temporarily hooking. All you have to do is pull it, and you can easily perform the temporary hanging work. In addition, the direction in which the fastener is pulled to finish hooking the fastener to the fastener after temporary hooking is also the direction in which the fastener should generate a pulling force for sandwiching the rod-shaped portion between the object body and the fastener. It is not necessary to match them, and since the bent portion in the stretching operation is formed by the temporary hooking claw portion, the stretching work until the hooking is completed can be easily performed thereafter.

In this case, the configuration (3) may be embodied as follows.
(4) As the temporary hooking portion, the hooking portion has a first axial hooking claw portion toward one end of the shaft and a first axial hooking portion toward the other end of the shaft along the axial direction of the rod-shaped portion. Equipped with 2 axial hanging claws

With the configuration (4), the hook ring portion of the fastener is pulled so as to expand in the axial direction of the rod-shaped portion, temporarily hooked on one of the axial hook claw portions, and then directed toward the axial hook claw portion on the opposite side. It suffices to pull it, and when it finishes hooking on the axially hooked claws on the opposite side, the fastener is firmly hooked between the axially hooked claws. Despite the fact that the work up to the temporary hooking and the work until the hooking is finished are easy, the fasteners are firmly hooked without being inadvertently disengaged. In this way, the effect of reducing the stretching force in the stretching work when the fastener is hooked is more reliably exerted. As a result, for example, it is not necessary to use a thick rubber band, it is no longer necessary for the hooking portion to protrude greatly to the side, and the effect of reducing the outer dimension of the object is also exhibited.

In the configuration (4), for example, instead of attaching a wall extending to the front side to the hooking portion to prevent the fastener from coming off, a protrusion in the vertical direction (axial direction of the rod-shaped portion) is attached at the time of mounting. It is advisable to have a structure in which the amount of tension of the fastener is reduced to reduce the mounting force.

In this case, the following configuration may also be provided.
(5) A gap is provided between the axially hanging claws so that a finger can pass through.

This is because the provision of the configuration (5) facilitates the temporary hanging work and facilitates the work until the hooking is completed after the temporary hanging work.

Further, the configuration (2) may be embodied as follows.
(6) As the stretching force reducing structure, it is possible to move between the temporary hanging position and the main hanging position, and at least while moving from the temporary hanging position to the main hanging position, the hanging ring portion of the fastener is hooked. Must be equipped with a mobility assisting means that can be used.

The hanging ring portion of the fastener may be temporarily hung on the moving force assisting means at the temporary hanging position, and then the moving force assisting means may be moved to the main hanging position.

The moving force assisting 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 hanging position to the main hanging position.

For example, "(6A) As the stretching force reducing structure, at an intermediate position in the axial direction of the rod-shaped portion of the hooking portion, between a tilted position tilted toward the back surface and a rising position raised toward the front side. It is preferable to adopt the configuration of "providing a rotating member capable of temporarily hanging the hanging ring portion at the tilted position."

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

The rotating member can be configured by a lever attached to an object. In addition, the fastener is not a special thickness shape, but a general-purpose O-ring, and when this O-ring is hooked on the lever and the lever is raised, the main body can be turned into a golf club shaft, etc. with less force by the principle of the lever. Can be attached to the rod-shaped part of. Further, in the case of the above mounting method, the rubber has a special shape, but 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 structures are required to prevent the lever from coming off due to the force applied to the lever when it is attached to a golf club or the like, which may increase the number of parts and complicate the structure.

The object mounting structure of the present invention may further include the following configurations.
(7) The fastener is composed of an elastic ring-shaped member that is closed as a whole, and at least a part thereof is provided with an insertion port having a size smaller than the cross-sectional dimension of the elastic ring-shaped member, and the positions of both ends of the rod-shaped portion in the axial direction. Provided the object with a holding portion for retaining the stopper corresponding to the hooking portion.

By adopting the configuration (7), it is possible to perform the hooking work in a state where the fastener is firmly pulled in parallel in the vertical and horizontal directions by using the temporary hooking state, and the mounting state of the object becomes more stable. .. Then, in order to achieve such a stable pulling state, it is possible to complete the work of hooking the fastener by using the principle of leverage from the temporarily hooked state or by stretching work in the axial direction other than the final pulling direction. As a result, even if an object having a relatively small diameter is used, a sufficient tensile force can be exerted to make the attachment of the object robust. As a result, for example, it is possible to carry out the present invention 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 composed of a composite ring-shaped member having a plurality of closed openings arranged in the axial direction of the rod-shaped portion, and the hooking portion is formed of the composite ring-shaped portion. The free end side of each opening of the member shall be composed of 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 in which a plurality of rubber bands are integrated may be imagined, and as a result of having three or more portions stretched in parallel in the pulling direction, the respective diameters. Even if you make it thinner, you can hook the fastener in a state where a firm pulling force is generated. By reducing the diameter of each part, the stretching force during hooking work is reduced. Further, even if one of them is cut, the object will not fall off because it will not be released from the hooked state.

In this case, it is particularly preferable to configure as follows.
(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 hooking portion has a comb-shaped structure having three or more hooking 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 of them is cut, the remaining three can firmly maintain the mounted state. As a result, if the fastener is made of rubber parts, it can be made thinner. This is a result of having four or more parts that exert a pulling force and firmly fulfilling the role of a safety device. As a result of making it thinner, the external 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 is provided with a contact member on the back surface side that is compressed and deformed by the tensile force generated in the fastener.

By also providing the configuration (10), the compression deformation of the contact member on the back surface of the object strengthens the pinching to the rod-shaped portion, and pressure contact due to friction in the mounted state can be expected, and the mounted state becomes more stable. .. This contact member also functions as a non-slip member.

In this case, the following configurations can also be provided.
(11) The rod-shaped portion has an outer surface shape having a different diameter depending on its axial position, and the contact member is provided with a surface corresponding to the outer surface shape on the back surface side.

By also providing the configuration (10), the object can be attached to the object more stably. For example, the shaft of a golf club may be tapered so as to become thinner from the grip toward the head, or it may be gradually tapered with a step. Baseball bats gradually thicken from the grip to the tip. In the configuration (10), for example, the rubber applied to the club is tilted according to the tilt of the shaft so as to correspond to the shaft of the golf club, so that the force against which the rubber is pressed when the rubber is attached to the club is made as constant as possible. It is a thing. For example, the contact member may be provided with 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 having a diameter different depending on its axial position, the object and the object are subjected to compressive deformation of the contact member on the back surface of the object. By improving the adhesion and making the back surface side of the contact member an inclined surface or a stepped surface, high adhesion can be maintained even when the diameter of such a rod-shaped portion changes in the axial direction. This makes it possible to prevent the object from being tilted and mounted, or from becoming an unstable mounting state such that there is a gap on the lower end side.

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

The abutting member has the effect of improving the adhesion between the object and the rod-shaped portion, but if the rod-shaped portion does not correspond to the back surface of the abutting portion, an unstable mounting state with a gap may occur. This is because the configuration (12) can be used to replace the contact member with a back surface corresponding to the outer diameter and taper angle of the rod-shaped portion of the object. By adopting a structure in which the non-slip contact member can be easily removed, for example, a battery can be placed in a portion where the contact member is attached so that the battery can be replaced. Further, for example, it is possible to prepare a rubber contact member suitable for each type of golf club and replace it to improve the anti-slip effect when the object is attached.

When such a detachable contact member is provided, the following configuration may be further provided.
(13) The contact member is configured so that the amount of compression deformation increases toward the outside from the axis of the rod-shaped portion.

The abutting member is different from a simple plate-shaped rubber attached to the back surface of an object, and is abutted so that the amount of compression deformation increases from the axis of the rod-shaped part to the outside, and the fastener is far from the axis. As a result of the contact member being compressed and deformed more strongly on both ends, a strong adhesion force is generated.

In this case, the following configuration may be further provided.
(13A) The contact member is composed of an elastic member having a flat surface on the front side and a recessed surface on the back surface side, and has a frame-shaped rib protruding toward the front around the flat surface. The object is provided with a frame-shaped portion corresponding to the frame-shaped rib, and has a housing having an internal structure in which a gap remains on the front side of the flat surface at the time of compression deformation, and the housing side is contained in the gap. Detachably accommodates parts that are thicker than the height of the frame-shaped part.

According to the configuration (13A), in the abutting member, the frame-shaped rib abuts on the frame-shaped portion on the housing side at a position close to both ends of the fastener, and the abutting member is relatively thick in the portion. The amount of compression deformation increases accordingly. On the other hand, since the gap formed between the flat surface of the contact member and the housing is not subjected to pressure, the parts housed in the gap are not damaged by pressing, and the gap is removed by removing the contact member. When taking out the inner part, the back surface of the component has an edge protruding toward the back surface side from the frame-shaped portion of the housing, and the component can be easily removed by hooking a finger on the edge.

These object mounting structures of the present invention may particularly have the following configurations.
(14) The object is a motion used to swing around, and the object is an electronic device having an electronic circuit built in the housing or a mounting tool for attaching an electronic device having an electronic circuit built in the housing. ..

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

As the object, it is preferable that an object attached to the rod-shaped portion of the object is subjected to a force to be separated from the rod-shaped portion of the object, particularly during normal use of the object.

The object may be a part of the object that is grasped and moved by a person. Especially good for exercise. In particular, it is preferable to provide a grip as a grip portion and use the exercise to grip and swing the grip. Examples of the exercise used to grip and swing the grip include a golf club, a tennis racket, and a baseball bat. In order to acquire higher skill by using these movements, it is advantageous to detect the state of the swing with a swing sensor or the like. In this case, there is also a method of taking a picture of the swinging state of these moving objects from the side with a camera and analyzing or analyzing the image, but in that case, a shooting technique is required. On the other hand, if the sensor is directly attached to these moving objects, such high-level shooting technology 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, in the object mounting structure of the present invention, since the object mounting work is facilitated, the object can be mounted in an appropriate position in a stable state, so that swing detection with sufficiently improved accuracy is possible. do.

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

When the configuration (15) is adopted, when consciously operating the power switch of the electronic device attached to the moving object, this can be easily performed while holding the grip, and the on / off as intended. You can easily check whether it is in a state or not while holding the grip, which also has the effect of being easy to see. On the other hand, if the switch is not operated intentionally, the switch will inadvertently touch the body such as the thigh or other peripheral objects (in this specification, simply referred to as "thigh") due to the obstruction of the rod-shaped part. It doesn't happen, and the switch isn't turned on and off unintentionally.

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

In the configuration (16), when 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 unintentionally touches the thigh or the like and the terminal cover opens. Because there isn't. For example, by making the terminal cover difficult to open when attached to a golf club, it is possible to make it difficult for the main body to accidentally hit something and open the cover.

In this case, the following configuration may be further provided.
(17) The grip portion has an end portion that wraps around 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.

This is because the problem that the terminal cover cannot be opened carelessly can be almost completely avoided by providing the configuration (17) as well, although the terminal cover cannot be opened in the state where the object is attached.

Further, the object mounting structure of the present invention may further have the following configuration.
(18) An electronic device in which a contact member that is compressed and deformed by the tensile force of the fastener is detachably attached to the object from the back surface side of the object, and the object has an electronic circuit built in the housing. The replaceable parts are housed in the housing so that the circuit portion is located in 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 relatively highly destructible part on one end side in the axial direction of the rod-shaped portion and a relatively low destructible part on the other end side in the axial direction of the rod-shaped portion. The replaceable part is housed so that the relatively destructible part is located on the opposite side of the direction of the force received by the movement of the object.

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 relatively highly destructible part.

When the object is moved to swing 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, the inertia is in the direction opposite to the moving direction. Although force is generated, due to the above configuration, the circuit part of the replacement part and the parts with relatively high possibility of destruction are located on the opposite side to the direction in which these forces act, so that the important circuit part is the housing. 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 can be moved in the axial direction in the housing and is in a loosely stored state in a sense, an important circuit portion of the component is not abutted against the housing. As a result, for example, even if a replacement part such as a battery is easily replaced 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 capable of locating the lead wire on the side of the battery.

The configuration (19) protects the circuit portion on the battery side by intentionally lengthening the lead wire, facilitates replacement work because the lead wire is long, and even if the lead wire is long, when the object is attached. It will not be pinched and damaged.

The object mounting structure of the present invention may further have the following configuration.
(20) The object is a motion that is used by grasping and swinging a grip, and the object is an electronic device that houses a plurality of circuit boards connected by a board-to-board connector in a housing, and the housing is a housing. It is composed of a back side housing for fixing a circuit board on the back side of the plurality of circuit boards and a front side housing attached so as to close the front of the back side housing. Ribs are formed so as to project toward the back surface, and when the front side housing is attached to the back surface side housing, the ribs are the circuits on the front side of the plurality of circuit boards. The height should be such that it abuts on the surface of the board.

For example, when two circuit boards are installed in parallel in the housing of an electronic device such as a swing sensor attached to a golf club and connected by a board-to-board connector (BtoB connector), the club is swung to form a BtoB connector. The connection does not loosen. This is a structure in which the rib of the front side housing is brought into contact with the surface of the circuit board on the front side. As a result, even if a centrifugal force in the direction of loosening the connection acts on the circuit board, the force is applied by the rib. Because it can be accepted.

Further, the object mounting structure of the present invention may further include the following configurations.
(21) The object is a motion that is used by grasping and swinging a grip, and the object is an electronic device that houses a plurality of circuit boards connected by a board-to-board connector in a housing, and the housing is a housing. It is composed of a back side housing for fixing a circuit board on the back side of the plurality of circuit boards and a front side housing attached so as to close the front of the back side housing. Is attached to a cushion member that comes into contact with the surface of the circuit board on the front side of the plurality of circuit boards in a state of being attached to the housing on the back surface side.

Just as configuration (20) prevented the front circuit board from trying to move outward by the ribs on the front housing, configuration (21) allows the cushion member to be the front circuit. It is possible to regulate the movement of the board and prevent the connection between the board and the board connector (BtoB connector) from being loosened.

Further, the object mounting structure of the present invention may further include the following configurations.
(22) The object is a motion that is used by grasping and swinging a grip, and the object is an electronic device that houses a plurality of circuit boards connected by a board-to-board connector in a housing, and the housing is a housing. The plurality of circuits are composed of a back surface side housing for fixing the circuit board on the back surface side of the plurality of circuit boards and a front side housing attached so as to close the front surface of the back surface side housing. The boards are bonded to each other by 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 backside housing so that the circuit board on the front side tries to move out. By attracting the circuit board toward the circuit board on the back side, the movement of the circuit board on the front side can be restricted and the connection between the board and the board connector (BtoB connector) can be prevented from being loosened.

Further, in the object mounting structure of the present invention having at least the configurations of (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 changing structure, by appropriately changing the tightening strength with the fastener, it is possible to support both usage that emphasizes reduction of stretching force and usage that emphasizes increasing tightening force. .. The fastener may be provided on the body of the object with a tightening strength changing structure for changing the tightening strength, but it is particularly preferable to provide the fastener on the fastener.

In this case, the following configurations can be further provided.
(32) The tightening strength changing structure has a stepwise tightening strength changing structure that gradually changes the tightening strength.

By adopting a structure in which the tightening strength is changed stepwise, it is possible to accurately switch the usage as described above.

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

Use one of the hanging parts to reduce the stretching force and use it in an easy-to-use method, or use another hanging part to increase the tightening force, and firmly even for narrow objects. It can be used such as wearing it.

Further, in the object mounting structure of the present invention having at least the configurations of (1A) and (1B), the following configurations can be further provided.
(41) As the stretching force reducing structure, a cushion body having a thickness that can be compressed and deformed when tightened 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, and after mounting, the reaction force associated with the compression deformation of the cushion body exerts the tightening force together with the pulling reaction force of the fastener, and the stretching work can be performed. Despite the ease, it can be firmly attached.

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

Hereinafter, as an embodiment of the object mounting structure of the present invention, a golf swing sensor mounting structure will be taken as an example, and some embodiments will be described in detail with reference to the drawings. The golf swing sensor is attached near the grip of the shaft of the golf club and measures the acceleration information when the golf club is swung. Based on the acceleration information detected by the sensor, the swing is performed by dedicated software. It is intended to be useful for correcting the habits of the player by displaying the trajectory and the like.

In the golf swing sensor mounting structure as the first embodiment, as shown in FIG. 1, the shaft 3a of the golf club 3 is formed between the golf swing sensor 1 and the rubber band 2 spanned on the back surface side of the golf swing sensor 1. It is a mounting structure that sandwiches.

In this mounting, first, as shown in FIG. 1 (B), the rubber band 2 has one end 2a (hereinafter referred to as "former end 2a") on the left side surface of the rear housing 11 of the golf swing sensor 1. It is attached so as to be in a state of being prevented from coming off from the band holding hooks 12a to 12c formed so as to project laterally from the hook. Then, while pressing the rubber contact member 20 attached to the back surface side of the golf swing sensor 1 against the shaft 3a at a position close to the grip 3b of the golf club 3, the other end 2b of the rubber band 2 (hereinafter, hereinafter, The "free end 2b") is hooked on the hooks 13a to 13c for hooking 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. 1 (C), the golf swing sensor 1 is sandwiched between the rubber contact member 20 and the rubber band 2 from the front and back so that the shaft 3a of the golf club 3 is sandwiched between the shaft of the golf club 3 and the shaft 3a of the golf club 3. It is attached to 3a. In this state, a pulling force is generated on the rubber band 2 in the hanging direction, and a force that tries to contract against the pulling force acts as a force for tightening the shaft 3a of the golf club 3.

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

In this embodiment, the upper and lower openings 2c and 2e are elongated elliptical circles having the same vertical dimension (hereinafter referred to as "width") and lateral dimension (hereinafter referred to as "length") having the same shape. It has a shape. The central opening 2d is a rectangular opening having four corners rounded so that the length is equal to the upper and lower openings 2c and 2e and the width is about twice that of the upper and lower openings 2c and 2e.

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

Each of the openings 2c to 2e is integrated by a flat plate-shaped portion 2j so as to fill the adjacent R-angle portions even on the free end 2b side. The flat plate-shaped portion 2j has the same wall thickness as the diameters of the string-shaped portions 2f to 2i, and the upper and lower edges are formed as semicircular edges continuous with the outer surfaces of the string-shaped portions 2f and 2i. A bulging portion 2k is integrally formed at the end of the flat plate-shaped portion 2j opposite to the opening so as to bulge in the front-rear direction. The flat plate-shaped portion 2j has an area that can be picked up by a finger, and the bulging portion 2k has an anterior-posterior surface continuous from the free end side end of the flat plate-shaped portion 2j, and gradually toward the free end. The wall thickness is thickened to a maximum of about 3 times, and it plays a role of making it difficult for the finger picking the front and rear surfaces of the flat plate-shaped portion 2j to come off in the free end direction.

In this embodiment, each opening 2c to 2e of the rubber band 2 formed in the shape of a composite ring serves as 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 the openings 2c to 2e of the rubber band 2 can be hooked at the same time. The rear housing 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 the cross section, and the front side of the rear housing 11 are closed to close the rear housing 11. A housing 10 composed of a front housing 15 forming a storage space for storing a substrate or the like is provided between the two.

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

As shown in FIG. 3C and the like, the hooks 12a to 12c and the hooks 13a to 13c are projected from the left and right side surfaces of the rear housing 11 so that the positions in the vertical direction and the protrusion amount in the horizontal direction are symmetrical. Has been done. Further, as shown in FIG. 3A and the like, the hooks 12a to 12c and the hooks 13a to 13c have the same protrusion amount in the front-rear direction. As a difference, as shown in an enlarged manner in FIGS. 4A and 4B, the hooks 12a to 12c have protrusions 14a to 14c for preventing the hooks from coming off inward on the inner surface of the tip of the wall-shaped portion extending forward. It has been projected. The distance between the tip of the protrusions 14a to 14c and the left and right side surfaces of the rear housing 11 is made smaller than the diameter of the portion of the original side end 2a of the rubber band 2, and the rubber band 2 is attached to the hooks 12a to 12c. As shown in FIG. 1B, the rubber band 2 is integrated with the golf swing sensor 1 when the golf club 3 is attached to the shaft 3a. It is designed so that it does not deviate from 1.

As shown in the rear view of FIG. 3E, the front housing 15 and the rear housing 11 are integrated with two screws to form the housing 10. A rectangular recess 11a for mounting the rubber contact member 20 is formed on the back surface side of the rear housing 11.

The rubber contact member 20 has an outer shape having dimensions that fit into the rectangular recessed portion 11a, has a flat surface 21 on the front side, and has a wall thickness of a V-groove portion 22 running in the vertical direction on the back surface side. It is configured as a rubber molded body. As shown in the enlarged views of FIGS. 4A and 4B, the V-groove portion 22 has a contact surface 22b that is tapered rearward as a whole so that the groove bottom 22a becomes the back surface side as it goes down. It has. This corresponds to the tapered outer surface shape of the shaft 3a of the golf club 3 so that the grip 3b side is thick and the head side is thin, as shown in FIGS. 1B and 1C. be.

Further, as shown in FIG. 7, the rubber contact member 20 is formed with an engaging recess 23a formed by cutting out a side surface from the front to the middle of the rear at the upper left and the lower portion of the flat surface 21 on the front side. ing. Further, the circular recess 23b located on the height center line of the upper one of the engaging recesses 23a is also formed so as to be recessed rearward from the flat surface 23.

In the rectangular recessed portion 11a of the rear housing 11, a circular protrusion 11b is projected from the front to the rear, and an engaging convex portion 11c is formed so as to project inward from the left and right side surfaces. These engaging protrusions 11c are for fitting with the engaging recesses 23a of the rubber contact member 20 so that the rubber contact member 20 is attached to the rectangular recessed portion 11a of the rear housing 11 so as not to come off. It is a thing. Further, the circular protrusion 11b is for positioning by fitting with the circular recess 23b of the rubber contact member 20 at that time. As a result, the rubber contact member 20 that is separate from the housing 10 is positioned so as to fit into the rectangular recessed portion 11a of the rear housing 11, and is in a retaining state and is in a retaining state. It will be attached to the back side of.

In this mounted state, as shown in FIGS. 4A and 4B, the contact surface 22b of the rubber contact member 20 is located on the back surface side of the arcuate recess 11d formed in the rear housing 11. The wall thickness of the rubber contact member 20 is designed so that the rubber contact member 20 is in such a state. As a result, in the mounted 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 pull of the rubber band 2. It will be sandwiched from the front and back by. At this time, the rubber contact member 20 is in a contact state due to a line touch between the two contact surfaces 22b of the V-groove portion 22 and the shaft 3a. Since the rubber contact member 20 has a sufficient wall thickness at the portion contacted by the line touch, it is possible to sufficiently exert the force against the above-mentioned compression. Further, since both the contact member 20 and the band 2 are made of rubber, the frictional force stabilizes the mounted state of the golf swing sensor 1.

Since the contact member 20 itself is made of rubber, it can be removed by bending it with a finger if it is necessary to replace it. This makes it possible to easily replace the golf club with one having a contact surface shape with improved adhesion to the shaft depending on the type of golf club.

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

In this assembly, the sensor board 31 and the Bluetooth board 32 are assembled in a parallel integrated state via the BtoB connector 34. At this time, the sensor board 31 is in a state where the front surface of the edges of the upper and lower cutout portions 31a and 31b at diagonal positions is in contact with the rear end of the screw boss 15h projecting from the inner surface of the front housing 15. It is positioned so as to be, and is fixed to the front housing 15 with screws.

On the inner surface of the front housing 15, a horizontal rib 15i projecting rearward is provided so as to face a portion where the front surface of the Bluetooth substrate 32 is exposed. The height of the horizontal rib 15i in the front-rear direction is the height at which the front surface of the Bluetooth substrate 32 assembled by the BtoB connector 34 just abuts on the front surface side of the sensor substrate 31 when the sensor substrate 31 is screwed and fixed to the front housing 15. Has been done. As a result, the Bluetooth substrate 32 is assembled in the housing in a state where the front surface is pressed by the horizontal rib 15i of the front housing 15 so as not to be displaced in the front-rear direction.

Further, at the time of this assembly, the tip of the light guide body 35a of the LED component 35 provided on the upper front surface of the sensor board 31 faces the circular hole 15e of the upper tapered surface 15b of the front housing 15, and the sensor. The tip of the operation portion 36a of the slide switch 36 provided on the upper portion of the back surface of the substrate 31 is made to protrude from the switch window 15d on the upper end surface 15c 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 in the lower part of the back surface of the sensor board 31 from below. The terminal cover 40 is attached to the housing 10 so that the hinge portion 41 is on the front side and the knob portion 42 is on the back side. At this time, the terminal cover 40 fits in the recess 15k formed around the terminal window 15g on the bottom surface 15f of the front housing 15 and the recess 11k on the bottom surface of the rear housing 11 (see FIGS. 6 and 7). Is mounted so as to be substantially flush with the housing 10. As shown in FIG. 5B, the knob portion 42 of the terminal cover 40 can be opened by inserting a fingertip into the recess 11k extending to the back 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 storage frame 11 m on the front side of the rear housing 11. Therefore, the battery 33 is housed in the back side of the sensor board 31, and the wiring can be connected to the sensor board 31 from the back side. If a connector is used for the connection portion, it can be replaced, and by removing the rear housing 11, it is possible to easily replace it with a new one.

According to the first embodiment described above, the rubber band 2 is provided with three openings 2c to 2e, and the housing 10 is provided with hooks 12a to 12c and 13a to 13c having a comb-like structure having three comb teeth. By providing the three openings 2c to 2e as hanging rings and hanging them between the hooks 12a to 12c and the hooks 13a to 13c, the four string-shaped parts 2f to 2i of the rubber band 2 are provided. As a result of configuring the shaft 3a of the golf club 3 to be sandwiched between the rubber contact portion 20 and the string-shaped portions 2f to 2i by the pulling force generated in the above, each of the string-shaped portions 2f to 2i is formed by the thin rubber string portion. It can be configured and the stretching force when hooked on the hooks 13a to 13c can be reduced. Further, the holding hooks 12a to 12c are provided with protrusions 14a to 14c for preventing the golf club from coming off, and the mounting work can be performed after the hooks 12a to 12c are in the state of being prevented from coming off as shown in FIG. 1B. As a result, the shaft of the golf club 3 The work of pressing the sensor 1 against 3a and turning the rubber band 2 to the back of the shaft 3a is easy, and the sensor 1 does not easily shift from the desired position in the work of pulling the rubber band 2 after turning the back of the shaft 3a. As a result of reducing the stretching force, the work of hooking the hanging ring portion (the free end side of the openings 2c to 2e) to the hooks 13a to 13c can be easily executed.

Further, since the rubber band 2 is provided with four string-shaped portions 2f to 2i, even if one of them is cut, the other portions are connected, so that the sensor body is from the golf club 3. It can also serve as a safety device that can be removed. By having the role of this safety device, the string-shaped 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. It also has the effect of reducing the external dimensions of the sensor body.

Further, in this embodiment, as a result of sandwiching the shaft 3a between the rubber contact portion 20 on the back side of the sensor body and the rubber band 2, a firm mounting 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 contact surfaces 22b and 22b corresponding to the taper of the shaft 3a of the golf club 3 that becomes thinner toward the tip, the rubber contact member 20 is provided with the shaft 3a. The force pressed against the sensor becomes constant, and problems such as the sensor being tilted and attached 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 operate the switch while holding the grip 3b of the golf club 3, and the switch is switched by inadvertently touching the thigh or the like. It is hard to cause the problem of getting rid of it. In addition, as a result of being able to see the LED from the upper tapered surface 15b, it is possible to easily check the state of the power supply even while holding the grip 3b of the golf club 3.

Further, since the terminal cover 40 is mounted so that the hinge portion 41 is located on the front side and the knob portion 42 is located on the back surface side, the terminal cover 40 is configured to fit flush with the bottom surface of the housing, so that the terminal cover 40 can be placed on the thigh or the like. The problem of accidentally opening it by touching it is unlikely to occur.

Further, the free end side of the rubber band 2 is provided with a flat plate-shaped portion 2j and a bulging portion 2k, which makes it easy to pick with fingers and makes it difficult for the picked fingers to come off, improving operability in pulling operation. ..

Further, the rubber contact member 20 that guarantees the resistance to slippage due to friction when attached is not merely a rubber plate stretched, but is in contact with a line touch at a position outside the axis of the shaft 3a. As a result of the sufficient wall thickness of the contact portion and the enhanced compressive deformation ability, the adhesion is enhanced.

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

The Bluetooth board 32 assembled in the housing is detachable from the sensor board 31 with the BtoB connector 34, but in the assembled state, it is in a state of being abutted against the horizontal rib 15i of the front housing 15. Even if the golf club 3 is swung, it does not shift in the housing, and as a result, the BtoB connector 34 does not loosen and causes various functions of the sensor to malfunction.

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 almost the same configuration as that of the first embodiment, and a sensor board, a Bluetooth board, and the like are housed inside the housing 110 formed by assembling the front housing 115 and the rear housing 111. The switch is exposed from the upper end surface 115c, and the light guide body of the LED is seen through the upper tapered surface 115b. Further, a thick rubber contact body 120 having a V-groove portion is detachably attached to the back 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.

As another difference, in the second embodiment, since the rubber ring 102 having a simple ring shape is used, as a hook serving as a holding portion, as shown in FIGS. 9A and 9B, the rear housing 111 is used. A hook 112 having a large width in the vertical direction is adopted, which protrudes to the left from the left side surface of the hook 112 and bends forward, and is provided with a plate-shaped protrusion 114 projecting inward in the middle of the vertical direction of the hook 112. It is configured so that one end of the rubber ring 102 can be held in a state where it is prevented from coming off.

Further, as one of the features of the second embodiment, instead of the hooks 13a to 13c of the first embodiment, a hooking portion 113 provided with a rotating lever 113a is provided on the right side surface of the rear housing 111. The rotating lever 113a is a U-shaped spring steel rotatably mounted from the inside of the upper and lower boss portions 113b, and is tilted to the back surface side (FIGS. 9A and 9D). It can be rotated between the start-up position (see FIGS. 9B and 9E) raised up to the front side, and the start-up position is from the front side to the rear side of the boss portion 113b. We adopted a structure that fits into the groove 113c formed so as to cut toward the surface and does not come off carelessly.

Further, the rotation lever 113a has a portion on the root side as an inner bent shape portion 113e so that the U-shaped main body 113d is in a state of approaching the housing 110 side at the rising position. As a result, the rubber ring 102 can be hooked on the outside of the boss portion 113b by sliding it into the front position of the boss portion formed between the inner bent shape portion 113e and the housing 110. ..

For mounting, after holding the rubber ring 102 on the hook 112, set the sensor so that the rubber contact member is pressed against the shaft 3a, tilt the rotary lever 113a to the tilted position, and rubber. While pulling the free end of the manufacturing ring 102, hook it from the tip of the rotating lever 113a so that it is temporarily hooked (see FIG. 9D). Next, the rotation lever 113a is rotated to the rising position (see FIG. 9E). As a result, the rubber ring 102 can be stretched with a small force by the principle of the lever, and the sensor 101 is brought to the shaft 3a of the golf club in the state of the main hook in which the rubber ring 102 is caught on the outside of the boss portion 113b. Can be attached.

In this embodiment, the assist force of the rotary lever 113a is used to facilitate the attachment work of the rubber ring 102, and it is also possible to use a general-purpose O-ring or other component. This is a result that the rubber ring 102 can be stretched firmly without applying a large force by the principle of the lever, and even if "O-ring with a large diameter" or "O-ring with a small inner diameter" is used. Since the device can be stretched firmly with a small amount of force and the device can be held down, the force required for stretching by the person performing the mounting work can be reduced.

Next, Example 2 will be described with reference to FIG. The third 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 and second embodiments. The golf swing sensor 201 has substantially the same configuration as that of the second embodiment, and the sensor substrate and the Bluetooth substrate are housed inside the housing 210 formed by assembling the front housing 215 and the rear housing 211. The switch is exposed from the upper end surface 215c, the light guide body of the LED is seen through the upper tapered surface 215b, and a thick rubber contact body 220 having a V groove portion is detachably attached to the back surface of the rear housing 211. There is.

Further, also in the third embodiment, as in the second embodiment, a rubber ring 202 using a general-purpose O-ring as shown in FIG. 10B is used as a fastener. Since the rubber ring 202 having a simple ring shape is used, the hook serving as the holding portion protrudes to the left from the left side surface of the rear housing 211 and bends forward in the vertical direction as in the second embodiment. A wide hook 212 is adopted, and a plate-shaped protrusion 214 projecting inward in the middle of the vertical direction of the hook 212 is provided so that one end of the rubber ring 202 can be held in a detached state. did.

On the other hand, unlike the second embodiment, the hook for hooking is projected from the right side surface of the rear housing 211 to the right and has an upward hooking claw portion 213 m as shown in FIG. 10 (A). It is provided with an upper hook 213a and a lower hook 213c which is similarly projected to the right from the right side surface of the rear housing 211 and has a downward hook claw portion 213n. A gap 213b is formed between the upper hook 213a and the lower hook 213c so that a finger can pass through.

For mounting, after the rubber ring 202 is held in the hook 212, the sensor is set so as to press the rubber contact member against the shaft 3a, and as shown in FIG. 10 (C), it is made of rubber. Hook the free end side of the ring 202 on the upper hook 213a from above. This state is a temporary hanging state, and can be carried out only by slightly stretching the rubber ring 202. After that, a finger is hung on the portion hanging in the gap 213b, and the lower end of the downward hooking claw portion 213n is evaded so as to be stretched downward and hooked on the lower hook 213c to be in the main hooking state. The operation of temporarily hanging the rubber ring 202 after temporarily hanging it on the upward hanging claw portion 113 m becomes easy as a result of the temporary hanging forming the starting point of stretching. As a result, the work of attaching the sensor 201 to the shaft 3a of the golf club can be easily carried out.

It should be noted that the temporary hook may be set as the lower hook 213c instead of the upper hook and pulled upward for the main hook. In any case, instead of bending the tip of the hook on the hook side forward to create a wall in the diameter direction of the club shaft, a protrusion in the vertical direction (axial direction of the club shaft) is attached, and when installing. In the third embodiment, the structure is such that the pulling amount of the rubber ring 202 is reduced to reduce the force at the time of mounting.

Next, Example 4 will be described with reference to FIG. The fourth 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 to third embodiments. Further, the golf swing sensor 301 has the same structure as that of the third embodiment in terms of the structure of the hook and the like. The difference is that, as shown in FIG. 11, a frame-shaped rib 326 projecting toward the front is provided around the flat surface 321 on the front side of the rubber contact member 320, and the rear housing 311 has a rectangular shape. A frame-shaped portion 316 corresponding to the frame-shaped rib 326 is provided around the recessed portion 311a, and the rubber contact member 320 and the rear housing 311 apply pressure at the time of sensor mounting to the frame-shaped rib of the contact member 320. It is different from the third embodiment in that it is received by the 326 and the frame-shaped portion 316 of the rectangular recessed portion 311a of the rear housing 311. The configuration of the rubber contact member 320 on the back surface side is the same as that of the third embodiment.

As a result of adopting such a configuration, when the rubber contact member 320 is compression-deformed, it is provided with an internal structure in which a gap remains on the front side of the flat surface 325. Since this gap has a depth obtained by adding the height of the frame-shaped rib 326 and the height of the frame-shaped portion 316, instead of the battery 33 adopted in the first embodiment, a plate-shaped battery 333 having a thickness that fits in the gap is used. Another feature of Example 4 is that it is stored.

The plate-shaped battery 333 is provided with a substrate portion 333a at one end in the longitudinal direction, and has a configuration in which a lead wire 333b extended from the substrate portion 333a is connected to a sensor substrate via a connector 333c at the tip thereof. It has become. The connector 333c has a structure in which a through window is formed in the lower portion of the rectangular recessed portion 311a and is attached to and detached from the sensor substrate in the housing.

The thickness of the battery body 333d of the plate-shaped battery 333 shall be larger than the height of the frame-shaped portion 316 formed on the rear housing 311 side, and a finger may be hooked when the rubber contact member 320 is removed. It has an easy structure. Further, the width of the plate-shaped battery 333 is narrower than the width in the left-right direction of the gap, and the length is also shorter than the length in the vertical direction of the gap, and the plate-shaped battery 333 is stored in a state of being movable in the axial direction in the gap. At this time, a lead wire 333b having a length that fits next to the plate-shaped battery 333 is adopted with the substrate portion 333a facing upward.

As a result, when the golf swing sensor 301 of the fourth embodiment is attached to the shaft of the golf club to swing, centrifugal force is generated in the axial direction of the shaft from the grip to the head, and the golf swing sensor 301 is stored in the gap in a loose state. The plate-shaped battery 333 moves toward the lower side of the housing, but since the plate-shaped battery 333 is housed so that the easily damaged substrate portion 333a faces upward, the substrate portion 333a is the inner surface of the rectangular recessed portion 311a. It is not strongly pressed against. Further, the pressure in the mounted state is received by the frame-shaped rib 326 on the rubber contact member 320 side and the frame-shaped portion 316 on the rear housing 311 side, which are in contact with each other around the gap. The substrate portion 333a is not damaged by the mounting pressure. Further, since the lead wire 333b also fits next to the plate-shaped battery 333, it is not damaged by the pressure at the time of mounting.

Next, Example 5 will be described with reference to FIG. Example 5 is the same as Example 4 except that the following points are different from those of Example 4. The difference is that the knob portion 442 of the terminal cover 440 has a length that allows it to wrap around to the arcuate recess 411d of the rear housing 411. As a result, the golf swing sensor 401 can be attached so as to sandwich the knob portion 442 of the terminal cover 440 between the shaft of the golf club and the like, and the risk of the terminal cover 440 being inadvertently opened by hitting the thigh or the like can be further reduced. The feature is that it 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 sandwiches the cushion member 539 on the front side of the Bluetooth substrate 532. As a result, the Bluetooth substrate 532 becomes a more stable mounting state. In this case, the mounting state of the Bluetooth substrate 532 is stable even without the horizontal rib 15i adopted in the first embodiment.

Example 7 is the same as that of Example 1, and as shown in FIG. 14, the golf swing sensor 601 has a Bluetooth substrate 632 bonded to the sensor substrate 631 with a double-sided adhesive mat 639. This also makes it possible to bring the Bluetooth substrate 632 into 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 adopted in the first embodiment.

Next, as Example 8, a golf swing trainer system will be described. As shown in FIG. 15, the golf swing trainer system 700 includes a trainer device 710, a motion sensor 730, and a mounting belt 750, and an angle adjusting bracket 770 is used as needed.

It has a terminal 717 and a micro SD insertion slot 718, and has a built-in rechargeable lithium-ion battery.

A window-touch type 3.2-inch ultra-bright full-color liquid crystal display is used for the display screen 711 to display the detection result and the remaining battery level. The menu button 712 is a button to be pressed when it is desired to display a menu screen on the liquid crystal display device 711 in order to execute various settings, selection of processing contents, and the like. The LED lamp 713 indicates a charging state, and lights up in red during charging and in blue when charging is completed. The detection sensor unit 715 is for executing various measurements such as head speed by directing this surface in the direction of hitting the ball. The power button 716 is a button for turning on / off the power of the trainer device 710. The micro USB terminal 717 is for attaching an accessory AC adapter when charging the lithium ion battery built in the trainer device 710.

The micro USB terminal 717 and the micro SD insertion slot 718 are always covered with the cover 719, and the AC adapter can be connected or the micro SD card can be attached / detached by opening the cover 719 when necessary.

As shown in FIG. 15B, the motion sensor 730 is equipped with a power switch 731 on the upper end surface, an LED lamp 732 on the diagonally inclined wall surface on the upper front surface, and a micro USB terminal 733 on the bottom surface, and is rechargeable. It has a built-in lithium-ion battery.

The motion sensor 730 has built-in sensors for motion detection having three axes of acceleration and three axes of angular velocity. The power switch 731 is a switch for turning on / off the power of the motion sensor 730. As will be described later, the LED lamp 732 indicates the state of the motion sensor 730 by the way it shines. The micro USB terminal 733 is for attaching the accessory AC adapter when charging the lithium ion battery built in the motion sensor 730, and is always covered with a cover.

The mounting belt 750 is an injection molded body made of synthetic rubber, and is for mounting the motion sensor main body 730 to a golf club. The angle adjusting bracket 770 is used by mounting the trainer device 710, and is used when the trainer device 710 is installed horizontally even on a non-flat ground.

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 trajectory. In this swing trajectory display, this system can switch between the state viewed from behind and the state viewed from above so that it can be viewed from various directions, and also records the direction of the head at the moment of impact. It is configured so that it can be done.

As shown in FIG. 16, the mounting belt 750 has a shape provided with three horizontally long openings 752c to 752e so as to be arranged in the vertical direction from the original side end 752a toward the free end 752b, and the motion sensor 730 is provided. As a portion that generates a tensile force when attached to the shaft of a golf club, four string-shaped portions 752f to 752i located above and below these three horizontally long openings 752c to 752e are provided.

These three horizontally long openings 752c to 752e include a first partition portion 752 m that reaches from the inner surface of the string-shaped portion 752f to the inner surface of the string-shaped portion 752i 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 by the second partition portion 752n reaching the inner surface of the string-shaped portion 752i from the inner surface of the string-shaped portion 752f at a position about 1/4 of the opening length on the right side thereof. It is divided into 752d1 to 752d3 and 752e1 to 752e3.

Further, the upper and lower horizontally long openings 752c and 752e have an elongated oval shape in the left-right direction having the same shape in the vertical direction (hereinafter referred to as "width") and the horizontal dimension (hereinafter referred to as "length"). It has become. The central horizontal opening 752d is a rectangular opening with four corners rounded so that the length is equal to the upper and lower horizontal openings 752c and 752e and the width is about twice that of the upper and lower horizontal openings 752c and 752e. It is a department. The small openings 752c1 to 752c3, 752d1 to 752d3, 752e1 to 752e3 also have rectangular openings with rounded four corners.

The four string-shaped portions 752f to 752i arranged in the vertical direction have an oval cross section having a long side approximately twice the diameter of the original side end 752a having a circular cross section, and each has a back surface. It is configured to be flush with the original side end 752a and thicker than that of the first embodiment so as to protrude to the front side. The amount of protrusion is such that the amount of protrusion does not protrude beyond the bulging portion 752k, and is sized so as not to cause a sense of discomfort in appearance. Further, these string-shaped portions 752f to 752i are integrated so as to fill the adjacent R angle portions of the horizontally long openings 252c to 2522e while being continuous with the portions constituting the original side end 725a at the original side end 752a. There is.

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

In this embodiment, the small openings 752c1 to 752e3 at the left end of each of the horizontally long openings 752c to 752e of the mounting belt 750 configured in the shape of a composite ring correspond to the hanging ring portion. Further, in the present embodiment, as described later, the small openings 752c2 to 752e2 in the center can be used as the hanging ring portion with the first partition portion 752 m as the original side end. The small openings 752c3 to 752e3 at the right end can also be used as a hanging ring portion in some cases, but in this embodiment, the second partition portion 752n is mainly for reinforcing the string-shaped portions 752f to 752i. It is provided to stabilize the extension of the string-shaped portions 752f to 752i 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 configurations such as an L-shaped hook are designated by the same reference numerals as those described in the golf swing sensor 1 of the first embodiment, and detailed description thereof will be omitted. In the motion sensor 730, the rubber contact member 735 mounted on the back surface side of the rear housing 11 has an arcuate groove portion 736 on the back surface side thereof, and has a rectangular wall thickness of 5 mm so as to cover the entire back surface. The difference is that the structure is such that a sponge body 737 having dimensions of 40.5 mm × 15 mm is attached. As shown in the cross-sectional view, the rubber contact member 735 is provided with an edge 738 having a height of 1 mm and a wall thickness of 1 mm, and the sponge body 737 is fitted inside the edge 738 to form an arcuate groove portion. It is pasted on the entire surface along the arc of 736. As a result of the sponge body 737 being attached so as to fit inside the edge 738, the edge does not easily rise even if the adhesive is peeled off during use. By providing the rubber contact member 737 with the edge 738, the effect of not impairing the function and appearance of the sponge body 737 is exhibited.

In the eighth embodiment, as shown in FIGS. 18A and 18B, the mounting belt 750 is formed so that its original side end 752a projects laterally from the left side surface of the rear housing 11 of the motion sensor 730. Attached to the band holding hooks 12a to 12c so as to be in a detached state, and as shown in FIG. 18C, attach the sponge body 742 on the back surface of the motion sensor 730 to the grip 3b of the golf club. While pressing against the shaft 3a at a close position, handle the free end 752b of the mounting belt 750 on the back surface of the golf club 3 so as to wind it while pulling it straight, and project it laterally from the right side surface of the rear housing 11. It is attached to the golf club so as to be hooked on the formed hooks 13a to 13c for hooking.

In this embodiment, since the club installation surface of the motion sensor 730 is a sponge body 737, the pulling force generated in the mounting belt 750 and the compressive force generated in the sponge body 737 act on the motion sensor 730 with respect to the golf club 3a. Can be firmly 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 the sensor mounting position calibration described later, it is better not to be too below the grip 3b when measuring the swing trajectory of the club, and the optimum mounting range is 2 to 5 cm from the lower end of the grip. Is the range of. At this time, the power switch 731 and the LED lamp 732 are attached so as to be located on the grip side.

As shown by the lower arrow in FIG. 18B, the first partition portion 752 m is attached and used so as to be in a state of being prevented from coming off from the hooks 12a to 12c for holding the band. It can also be installed so that it is tightened more tightly.

In using the trainer system of this embodiment, first, as shown in FIGS. 19A and 19B, the trainer device 710 and the motion sensor 730 are used by 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 light up in red during charging and in blue when charging is completed. When charging is completed, the micro USB terminal 781 is pulled out and the covers 719 and 734 are closed tightly. The trainer device 710 and the motion sensor 730 are provided with a configuration in which charging is automatically stopped when the battery is fully charged so as not to be overcharged.

Further, as shown in FIG. 20A, the cover 719 is opened, the micro SD card 790 is attached to the trainer device 710, and the cover 719 is firmly closed. A record of golf practice can be saved in this micro SD card 790, and it can be taken out and installed in a personal computer or the like. As shown in FIG. 20 (B), the angle adjusting bracket 770 is composed of a base 771 and a bracket 773 having a ball-shaped fitting portion 772, and as shown in FIG. 20 (C), the bottom surface of the trainer device 710. The protrusion 774 of the bracket 773 is inserted into the hole 710a provided in the bracket 773. By attaching this angle adjustment bracket 770, as shown in FIG. 20 (D), the trainer device 710 can be rotated in the vertical direction and the horizontal direction to adjust the angle so that the main body becomes horizontal. This makes it possible to perform accurate measurement even in an uneven place.

As shown in FIG. 21, the golf swing trainer system 700 of this embodiment uses the display screen 711 of the trainer device 710 to display four items of "head speed", "estimated flight distance", "ball speed", and "meet rate". It has a "swing mode" that can be displayed at the same time and an "Arc mode" that displays the "swing trajectory".

The "head speed" displayed in the "swing mode" is the speed of the club head, the "estimated flight distance" is the flight distance calculated from the club used and the head speed or the ball speed, and the "ball speed" is the speed of the ball. "Meat rate" is the value of "ball speed ÷ head speed" and represents the efficiency of the swing transmitted from the club to the ball. In addition, the display can be switched between horizontal one item display, history display, and graph display.

The "Arc mode" is a mode in which a motion sensor 730 is attached, and is configured to be able to switch to display of "face trajectory" and "shot data" in addition to "swing trajectory", and further, "Arc mode". It is also configured to be able to display a "model" for the "swing trajectory".

As shown in FIG. 22, the golf swing trainer system 700 of this embodiment is described above with respect to the display screen 711 of the trainer device 710 by transmitting and receiving by Bluetooth between the trainer device 710 and the motion sensor 730. It has a system configuration that 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. The output signal of the Doppler sensor 721 (one wave corresponding to the movement of the head of the golf club by 6 mm) is amplified by the amplifier 722, compared with the reference value by the comparator 723, and the Doppler pulse (high when it is above the reference value). If 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.

In the first microcontroller 724, the swing speed (head speed) is calculated based on this Doppler pulse. Further, the signal amplified by the amplifier 722 is input to the second microcontroller 725.

In the second microcontroller 725, the ball speed is calculated 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 the meet rate based on the head speed calculated by itself and the ball speed calculated by the second microcontroller 725. Then, the first microcontroller 725 displays on the display control unit 726 and records on the recording unit 727 based on the data of the head speed, the ball speed, the estimated flight distance, and the meet rate. The first microcontroller 724 executes display switching, mode switching, and the like by input from the switch group 728. Then, 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 adjust the amplification factor with respect to 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 inputs the detection signal of the sensor 742, executes necessary arithmetic processing, and transmits the detection signal via 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 device 710, and various displays in the above-mentioned Arc mode are executed. The sensor 742 is a sensor for motion detection having three axes of acceleration and three axes of angular velocity. The microcontroller 741 also executes a process for responding to a data transmission request received from the trainer device 710 via the transmission / reception unit 745. Further, the microcontroller 741 controls the lighting / blinking state of the LED lamp 732 via the LED control unit 743.

FIG. 23A shows the details of lighting / blinking control of the LED lamp 732 by the microcontroller 741 of the motion sensor 730.

(1) In the "charging" state, "red" is lit.
(2) In the "charging (power on)" state, "red" and "yellow" are turned on alternately. The blinking patterns of "red" and "yellow" in this case change depending on the Bluetooth connection status.
(3) When the state of "charging completed" is reached, "blue" is lit.
(4) In the state of "charging completed (power on)", "blue" and "light blue" are turned on alternately. The blinking pattern of "blue" and "light blue" in this case changes depending on the connection state of Bluetooth.
(5) In the state of "charge abnormality", it is turned on in "pink". This is to notify the user of the possibility of abnormal temperature or overcharging.
(6) In the "power on (Bluetooth / not connected)" state, "green" blinks quickly.
(7) In the "power on (during Bluetooth pairing)" state, "green" is turned on and off to slowly blink.
(8) In the "power on (Bluetooth / connected)" state, the pattern consisting of "green" lighting twice and turning off for a predetermined time blinks.
(9) In the state of "motion detection in progress", it lights up in "green". 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, the pattern consisting of "green" lighting twice and turning off for a predetermined time is blinked. "During motion calculation" is a state in which a swing trajectory or the like is calculated after a swing is performed. This is a display for waiting for the next swing until the state of (9) is "lit in green".

In the lighting pattern of (9) "continuation of green lighting" in the motion sensor 730, the first microcontroller 724 of the trainer device main body 710 detects a signal from the motion sensor 730 (transmitted at a sampling interval of 2 ms). It is started by notifying the motion sensor 730 that it is determined that the user is holding the golf club and is almost stationary based on the above. Further, in the blinking pattern of (10) "green on / off twice" in the motion sensor 730, the first microcontroller 724 of the trainer device main body 710 "to the ball" based on the detection signal from the motion sensor 730. It is started by notifying by wireless communication that it is determined that the impact is completed and the swing is completed.

Here, whether or not it is "almost stationary" is about "resting" so that even a user who has a habit of swinging the club back and forth after holding it does not cause chattering for the determination of the stationary state. The judgment conditions have a range. Further, the "end of swing" is determined by using the detection signal corresponding to the "impact of impact". Therefore, in the case of "missing swing", it is judged as "resting state release" instead of "swing end", but if you hold it again and take "resting state", it will be in the state of "green lighting continuation" and the swing will be measured immediately. It becomes possible to do.

In this embodiment, as shown in FIG. 23B, in the trainer device 710, the icon 711b indicating the charging state of the motion sensor 730 is displayed on the display screen 711 together with the icon 711a indicating the charging state of the main body. It also has a configuration to do.

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 the power button 716 is pressed and held for 2 seconds or longer in the power on state. It is configured to turn off the power. As shown in FIG. 24B, the motion sensor 730 is powered on by switching the power switch 731 on. As described above, immediately after the power is turned on, the LED lamp 732 is in the “green blinking” state. Note that FIG. 24B shows a state in which the power switch 731 is tilted to the off side.

After turning on the power of the trainer device 710, when the menu button 712 is pressed as shown in FIG. 24 (C), the 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. You can select the mode by touching the mode buttons on these menu screens with your finger.

(1) As described above, the "swing mode" is a mode in which "head speed", "estimated flight distance", "ball speed", and "meet rate" are detected and displayed. Also, if certain criteria are met, a "nice shot animation" will be displayed. Furthermore, it is also possible to display the average value of swing data for each club and the numerical value for each club. In addition, each item can be displayed as a graph.
(2) The "Arc mode" is a mode in which the motion sensor 730 detects and displays the trajectory of the club.
(3) The "setting mode" is a mode for changing the settings of the main body such as the date and time and the left-handed setting.
(4) The "practice mode" is a mode in which the target distance setting is automatically or manually set. In this mode, when a certain standard is satisfied, "nice on animation" is displayed.
(5) The "Arc reproduction mode" is a mode for reproducing the recorded swing trajectory (Arc).
(6) By touching "Power off", the power of the main body can be turned off without pressing and holding the power button 716.

To use 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 data management software, you can select files and compare data using the recording date and time as a marker. Immediately after installing the battery, the default setting is 0:00 on January 1, 2013.

As for the operation method, as shown in FIG. 25 (A), touch "Settings" on the menu screen and touch right scroll to display the "System tab". Next, touch "General", touch "General" on the switched screen, and touch "Date and time" on the switched screen. After that, operate the "numeric keypad", "clear", and "OK" to enter the year, month, day, hour, and minute in that order.

[Swing mode]
Next, the operation procedure of the "swing mode" will be described. As shown in FIG. 25B, when the "swing" on the menu screen is touched and the club button on the switched screen is touched, the club selection screen is displayed. In this embodiment, "wood", "utility", "iron", "wedge", and "putter" are prepared as the types of clubs that can be selected. To select the first wood, touch "wood" as shown in the figure, and then touch "1W" on the switched screen.

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

Here, in the system of this embodiment, the calculation process in which the "flying distance calculation standard" is defined as follows is performed.
(1) Calculated based on the coefficients obtained from a large number of data collections based on the general clubs on the market.
(2) The flight distance is calculated as a value including a run assuming an average spin amount, a windless state, and a flat terrain.
(3) The direction of the hit ball is not taken into consideration.
Depending on the club used, there may be an error between the flight distance display and the actual flight distance.

In order to calculate such a flight distance, 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. 25 (C).
The wedge has a configuration in which the initial setting value can be changed.

The "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 this embodiment is initially set to be displayed when the meet rate (ball speed ÷ head speed) becomes 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 this embodiment will be described. FIG. 26 shows the installation position and the like of the device when a wood-based club is selected. As shown in FIG. 26 (A), an obstacle is placed 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 so that there is no such thing. At this time, if the installation location has undulations, the angle adjustment bracket 770 is used (see FIG. 20 (D)). The figure shows the case of right-handed.

As described above, the system of this embodiment can display one item horizontally in addition to the simultaneous display of four items. Basically, four items are displayed at the same time, and as shown in FIG. 26 (B), when an item to be displayed is touched, the screen can be switched to a large horizontal display of the item. As a result, the user can often see the item that he / she wants to know most from the standing position in FIG. 26 (A).

When the user swings, the trainer device 710 executes 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. While this arithmetic processing is being performed, the message "Please wait" is displayed on the display screen 711. When the detection result is obtained, the detection result is blinked and displayed, and then switched to lighting to notify that the result has been updated.

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

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

The detection result obtained in this way can be recorded in which the acquisition date and the time are associated with the detected data by setting the "date and time" as described above.

In the following cases, it may not be displayed correctly.
(1) If the trajectory of the ball is high (the launch angle is large) or if it deviates to the left or right, the ball speed may not be detected.
(2) Since a club with a large loft angle also has a large launch angle, it may not be possible to detect the ball speed. Also, the value of the meet rate becomes low.
(3) When using a golf practice net or the like, if the distance from the ball placement position to the net is 3 m or less, the ball speed may not be detected.
(4) If the ball speed is less than 20.0 m / s, it cannot be detected.
(5) If the head speed is less than 15.0 m / s, it cannot be detected.
(6) If multiple units are used at a short distance, it may not be detected correctly. Therefore, when using a plurality of units, it is desirable to keep a distance of at least 2 m from each other.

The "nice shot animation" shown in FIG. 26C is configured to be displayed only when a wood-based club is selected. In the initial setting, "nice shot animation" is displayed when the meet rate becomes 1.40 or more. The "nice shot animation" also adopts a configuration that allows the setting to be changed to "not displayed".

Next, the installation position of the device when "putter" is selected in the "swing mode" will be described. In this case, first, as shown in FIG. 27 (A), touch "swing" on the menu screen, touch the club button, and select a putter. Next, as shown in FIG. 27 (B), the trainer device 710 is separated from the launch line of the ball by about 20 cm on the opposite side of the user, and the rear end is about 20 cm ahead of the position of the ball in the launch direction. The unit is located, and the detection sensor unit 715 is installed so as to face about 1 m ahead in the launch direction of the ball. Also at this time, the trainer device 710 and the ball are installed horizontally so that there are no obstacles, and when there are undulations, the angle adjustment bracket 770 is used. This figure also shows the case of right-handed.

When the user performs putting, the trainer device 710 executes arithmetic processing of ball speed measurement and estimated flight distance calculation based on the signal from the Doppler sensor 721, and as a detection result, as shown in FIG. 27 (C). The estimated flight distance and ball speed are displayed. It should be noted that the display of the "Please wait" message during the arithmetic processing and the switching of the display from blinking to lighting when the detection result is obtained are the same as in the case of Wood.

The following conditions are adopted in the measurement and calculation for this putting.
(1) The speed (stimp) of the green is calculated assuming 7.8 feet.
(2) If the moving distance of the ball 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, and other conditions.
(6) If multiple units are used at a short distance, it may not be detected correctly. Therefore, when using a plurality of units, it is desirable to keep a distance of at least 2 m from each other.

As described above, 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. Therefore, as shown in FIG. 28A, the "history display screen" can be called by touching the "history button" on the swing mode screen and then touching the "history display" on the switched screen.

The "history display screen" is configured to display 7 items at a time from the latest history, and by touching the "next page", the display is switched to the next 7 items. The example shown is for No. 1 wood, where "No." in the upper row is a serial number with the latest 1 in the history, "H / S" is the head speed, "distance" is the estimated flight distance, and "B /". "S" means ball speed and "meet" means meet rate. As a result of using a small screen, the item names are abbreviated and one time is displayed in one line.

In addition, the average value of head speed, ball speed, estimated flight distance, and meet rate is displayed at the top. This average value does not switch even if you touch the "next page" or "previous page", and by comparing it with the average value, you can know the result or failure of each swing.

You can see the history of the selected club by touching the club button and selecting another type of club. If no club is selected or all clubs are selected, the history is displayed without a numerical value in the average value column as shown in FIG. 28 (B). If only the head speed is detected, such as a swing, the ball speed and the meet rate will be blank.

As shown in FIG. 28C, when the “graph display” is touched on the history function selection screen, the screen switches to the history date confirmation screen. Touch "Date and time" to switch to the date specification screen, and touch the date you want to display in the graph to select the display target. If you touch "All" on the history date confirmation screen, you will not be taken to the date specification screen. In this embodiment, it is managed by the date, and the hour and minute are not specified.

When the date to be displayed in the graph is selected in this way, the "history display item selection screen" is displayed as shown in the upper column of FIG. 28 (D). When the user touches any of "head speed", "estimated flight distance", "ball speed", and "meet rate", the screen switches to the graph display screen corresponding to the touched item as shown in the lower column.

Each graph displays up to 100 data on one page, and the old data can be read and displayed by touching the return button, and the new data can be read and displayed by touching the forward button. .. In addition, by touching the club switching button, the club can be selected from this graph display screen. Furthermore, the display range of the vertical axis can be changed by touching the vertical axis setting button.

Next, saving the history will be described. As shown in FIG. 29 (A), touch "swing" on the menu screen, touch the "history button" on the switched screen as shown in FIG. 29 (B), and "save" on the history function selection screen. By touching, the trainer device 710 starts the process for saving the history to the SD card. While the save process is being executed, the message "Saving ... Please do not remove the SD card" and the symbol indicating the progress of the process are displayed as shown in the figure. When the save is completed, the message "Completed" is displayed.

To delete the history, touch the "History button" as shown in Fig. 29 (C), and then touch "Delete" on the history function selection screen, and the question message "Do you want to delete the history?" And display the "Yes" and "No" buttons to confirm. Then, when "Yes" is touched, the history erasing process starts in the trainer device 710. When the history deletion is completed, the message "History has been deleted" is displayed and the screen returns to the history screen after 2 seconds. Even when "No" is selected for confirmation, the screen returns to the history screen. When the history deletion is completed, the number of histories becomes 0.

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

When "automatic" is touched, the target distance is randomly set between 50 and 150 yards by the internal processing of the trainer device 710. When "manual" is touched, operate the numeric keypad to enter the target distance between 50 and 150 yards, and touch "OK" to set. As shown in FIG. 30D, settable ranges and initial setting values are defined for the upper and lower limits of the target setting distance, club selection, speed unit, flight distance unit, green radius, and nice-on animation display. The upper and lower limits of these target setting distances, the green radius, and the units of speed and distance can be changed by setting.

When the setting of the target distance is completed, touch the club button as shown in FIG. 30 (E) to execute the club selection. As shown, putters are not included in the selectable clubs. 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 a calculation process for determining whether or not to display the "nice on animation" by comparing with the target set distance.

As shown in FIG. 30 (F), the installation position of the device in the "practice mode" is the same as in the "swing mode", and the detection sensor unit 715 of the trainer device 710 is approximately rearward toward the direction in which the ball is launched. Install it horizontally so that there is no obstacle between the trainer device 710 and the ball at a position 1 to 1.5 m away.

When the user swings, the trainer device 710 executes 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, and detects the estimated flight distance. This detection result is blinking on the display screen. Then, when the estimated flight distance is within a radius of ± 10 yards of the target distance, a “nice-on animation” as shown in FIG. 30 (G) is displayed on the display screen. When the flashing of the detection result ends, the practice mode can be processed 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 in which the swing trajectory when swinging is recorded by using the trainer device 710 and the motion sensor 730. The motion is temporarily stored for each swing, but it disappears when the next swing is performed without saving it. To save, touch the "Save" button for each stroke, and save up to 30 items in the storage device of the trainer device 710.

First, as shown in FIG. 31A, the club is firmly attached using the attachment belt 750 so that the upper end of the motion sensor 730 is located 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 located on the opposite side of the face surface with respect to the shaft 3a, and the power switch 731 and the LED lamp 732 are attached so as to face the grip side.

After the motion sensor 730 is attached to the club shaft in this way, the club is selected next, and the sensor attachment position and the face surface are calibrated. For this operation, touch "Settings" on the menu screen as shown in FIG. 31 (B), and touch the feed switch on the setting screen to display the Arc tab as shown in FIG. 31 (C). Touch "Club" to display the club setting screen and select a club, then touch "Sensor mounting position" and enter the sensor mounting position by using the numeric keypad. The sensor mounting position is configured so that the distance from the tip of the head to the motion sensor 730 can be calibrated within a range of 50 to 100 cm.

When the calibration of the sensor mounting position is completed, return to the club setting screen and touch "Face surface calibration" as shown in FIG. 31 (D). Then, the trainer device 710 displays a screen showing the method of face surface calibration with figures and sentences on the display screen. The user performs an operation of touching "OK" with the club equipped with the motion sensor 730 facing the horizontal plane according to the instructions on the screen and the text. When "OK" is touched, the trainer device 710 communicates with the motion sensor 730 and calibrates the face surface. At this time, the process of detecting the positional relationship between the motion detection position and the face surface by the motion sensor 730 is executed by referring to the sensor mounting position data and the club selection data. When the calibration is completed, a message to that effect is displayed on the display screen. When performing this operation, the power of the motion sensor 730 is also turned on.

Next, as shown in FIG. 31 (E), as in the case of the "swing mode", the trainer device 710 is struck so that the ball is horizontal on a flat place without undulations and there is no obstacle between the ball and the ball. Install at a position about 1 to 1.5 m behind. By installing in this way, the measurement / calculation of the "Arc mode" and the "swing mode" can be executed at the same time. If the Bluetooth is connected between the motion sensor 730 and the trainer device 710, the measurement / calculation in the "Arc mode" is possible. Therefore, for users who do not need data such as head speed, the position is not limited to the installation method shown in FIG. 31 (E), and Bluetooth connection is possible in an environment where there are no obstacles or other radio waves generated in between. It suffices to install the trainer device 710 in.

After installing the motion sensor 730 and the trainer device 710 as described above, check that each power is 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 fast blinking "green", repeating lighting and extinguishing once, repeating lighting and extinguishing twice, and continuously lighting.

As shown in the table of FIG. 21 (A), the fast blinking of "green" is the "Bluetooth not connected state", the repetition of turning on and off once is "during bluetooth pairing", and the state of repeating turning on and off twice. Is "Bluetooth connection in progress" or "motion calculation in progress", and the lighting continuation state is "motion detection in progress". It is in the "green" continuous lighting state that the swing can be performed and the motion detection can be executed. The user can execute the swing at any time after confirming the continuous lighting state of this "green". The continuous lighting state of "green" is a state in which the club is stationary from the signal from the motion sensor 730, and the motion calculation processing is not performed on the trainer device 710 side. The determination of whether or not the club is in a stationary state is performed on the trainer device 710 side, and the 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 some users have a habit of subtly moving the club when taking an address position.

The user takes an address posture, confirms that the LED lamp 732 of the motion sensor 730 is continuously lit in green, and then swings. When using for the first time immediately after turning on the power, an image of a person holding a club as shown on the left side of FIG. 32 (B) is displayed. Even if you make a swing in this state, the motion calculation is not executed. This is because the trainer device 740 is set with a calculation condition that requires an impact on the ball for motion calculation.

When the user swings and an impact on the ball occurs, the hitting 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 the hit point. Then, as shown in the screen on the right side of FIG. 32 (B), an image of a person moves like swinging a club and a moving image in which a swing trajectory is drawn is displayed. The display of this video is played repeatedly, but it is not saved automatically. To save the swing trajectory, touch the "Save" button on the screen. The trainer device 710 saves data related to the swing trajectory currently displayed as a moving image when the touch to the save button is detected. The maximum number that can be stored in this embodiment is 30.

When you touch the screen that repeatedly displays the swing trajectory, as shown in FIG. 32 (C), the direction of showing the swing trajectory is "front (from above)", "rear", "top", "front". It switches to a different display. Each display is played repeatedly as a video.

Here, it is difficult to understand because the color cannot be displayed in the figure, but in this embodiment, 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 performed. A display mode is adopted in which the distinction between the two can be judged by the hue. In the case of a golf swing, a pole change point from the upswing to the downswing occurs, so the pole change point is calculated and the upswing part is blue, the downswing part is red, and so on. It may be a display mode to change. With these display modes, it is possible to distinguish between an upswing and a downswing even on the screen in a state where the swing trajectory has been drawn, and it is possible to more accurately convey information when correcting the trajectory. In this embodiment, since the process of drawing the swing trajectory is performed by the moving image, the trajectory of the upswing and the trajectory of the downswing can be distinguished by this as well.

In drawing the swing trajectory, 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. 32 (C), and the ball is in the center. The display mode is adopted so that it is positioned to the right of the right side. As a result, the swing trajectory can be drawn larger on the display screen.

If you touch "Switch", 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 can be switched between "face angle at impact" and "loft angle at impact". This screen is not a video, but a still image.

This face trajectory display is based on the data of the 3-axis acceleration and the 3-axis angular velocity detected at the sampling interval of 2 ms on the motion sensor 730 side, and the face orientation is calculated at the 2 ms interval on the trainer device main body 710 side, and the face is displayed. It is displayed on the screen in a display mode as a set of lines that intermittently change the surface. 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 figure, 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 above-mentioned display mode of the swing trajectory seen from the rear or the upper surface, the ball is shifted to the right so that the swing trajectory can be drawn large, whereas in the case of the face trajectory, the orientation of the face surface before and after the impact is accurate. In the sense of communication, it is suitable to display the ball so that the lowest point (ball impact position) is in the center. The sampling interval is preferably 2 ms or less, more preferably 1 ms or less.

Touch "Switch" while "Face trajectory" is displayed to switch to the "Swing data" screen, "Club type", "Upswing time", "Downswing time", "Face angle at impact", "Loft at impact". The screen switches to the screen that displays "corner" numerically.

In addition to being able to confirm the face angle and loft angle numerically as "swing data", by drawing the trajectory of the face surface at a sampling interval of 2 ms as the face trajectory, in addition to the numerical value, your swing can be more accurately imaged. It is possible to grasp.

If you touch "Switch" while "Swing data" is displayed, you will return to the video 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, it is possible to continuously execute the next swing to obtain the swing trajectory and the like. It has become. Therefore, the LED lamp 732 of the motion sensor 730 is in the state of "continuing to light green". When the user needs to save, he touches "Save" and then makes the next swing. If there is no need to save, the LED lamp 732 can be swung immediately after confirming "continue to light green".

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

[Model display]
Next, in the "Arc mode" and "Arc reproduction mode", the function of displaying the "model" in an overlapping manner when displaying the "swing trajectory" will be described. To use this function, touch "Settings" on the menu screen as shown in FIG. 34 (A), and then open the "Arc tab" and "Display" as shown in FIG. 34 (B). Touch, touch "Do not display model", touch "Display" on the opened screen, change to "Display model", and then touch "Back". By this operation, the display condition of the "swing trajectory" in the trainer device 710 is changed from the initial setting "do not display the model" to "display the model".

After setting to "Display model" in this way, as shown in FIG. 34 (C), if "Arc" is touched from the menu screen to activate "Arc mode", as shown in FIG. 34 (D). When displaying the swing trajectory, the model swing trajectory is displayed in an overlapping manner. This model is based on the data when the professional golfer swings using this 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 (slightly from above) → back → top → front → ..., and the model is superimposed on each screen. It is configured to be displayed.

Also, by setting to "Display model" and checking in "Arc playback mode", as shown in Fig. 35, you can correct the habit of making a big swing as shown in the lower row and get closer to the model as shown in the upper row. It can be utilized.

[Setting mode]
Next, the setting mode will be described. As shown in FIG. 36 (A), when "Setting" is touched on the menu screen, the setting screen is displayed as shown on the right side thereof. By touching the "send key" and "return key" on the setting screen, the setting target can be switched between "swing tab", "Arc tab", and "system tab".

An operation method for changing the display mode in the "swing mode" by using this "setting mode" will be described. As shown in FIG. 36 (B), if you want to switch the display position of "head speed" and "estimated flight distance" up and down, touch "display item" of "swing tab" to display the screen shown at the lower left end. Let me. Touching "Head Speed", which is the top display item on this screen, switches to the screen on the right side. If you touch "Estimated flight distance" on the switched screen, the screen will switch to the screen in which "Estimated flight distance", "Estimated flight distance", "Ball speed", and "Meet rate" are arranged in this order as shown on the right side. Next, touch "Estimated flight distance" on the second stage, and then touch "Head speed" on the switched screen. As shown on the rightmost screen, "Estimated flight distance", "Head speed", "Ball speed", and "Meet". The screen will be changed to "Rate" and the display position. By touching "Back" here, the setting in which the display order is changed is stored in the trainer device 710. After that, when the "swing mode" is activated, the display can be displayed in a state where the top and bottom of the display items are exchanged. By switching the order of the display items in this way, it is possible to change the target of horizontal display of one item by touching the screen.

Next, an operation method for changing the number of display items in the "swing mode" using the "setting mode" will be described. Touch "Settings" and "Display items" to display the screen with 4 items displayed 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 items is switched to "not displayed", 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, the screen for displaying three items can be displayed as in the second row at the bottom. Hereinafter, similarly, it is possible to set two-item display and one-item display.

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

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

As shown in FIG. 40, the first microcontroller 724 has a 16-bit counter (timer) 724a and a memory (RAM) 724b as a first storage means. A 2.5 MHz signal is input to the counter 724a as a reference pulse, and counting is performed. The value of the counter 724a can be captured in 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 is 16-bit wide and consists of 110 array areas (220 bytes in total).

The Doppler pulse output from the comparator 723 is input to the first microcontroller 724. The first microcontroller 724 measures the period of this Doppler pulse. A counter 724a is used to measure this cycle. Specifically, when the falling edge of the Doppler pulse occurs as a predetermined event, the falling edge 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 storage candidate data. Then, when a Doppler pulse fall detection interrupt occurs, the contents of the capture register 724c are recorded in the memory 724b as periodic data in the interrupt processing routine.

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

In each process executed by the first microcontroller 724, "waiting for start", "measuring", "completed", and "error" are defined as measurement states (process states), and each state is stored in the memory 724b. It is stored in the set state storage area, and the processing content is changed based on this stored state. The state "waiting for start" is a state of waiting for the fall of the first Doppler pulse. Immediately after reset (immediately after turning on the power), this state is set, the falling edge of the Doppler pulse is detected, and when the cycle is 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 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 in which the accumulated data is inspected and the speed is calculated. The state "error" is a state in which the accumulation of periodic data is completed, but the number of accumulated data does not meet the specified value. When this state is reached, the stored data is immediately discarded, and a process (not shown) is performed to return to the "waiting for start" state.

First, the counter overflow interrupt processing function executed by the first microcontroller 724 will be described with reference to the flowchart of FIG. 41. Since the counter 724a is 16 bits, a counter overflow interrupt occurs when the counter value reaches 65535 + 1, 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 1. In the following S120, it is determined whether the measurement state is "waiting for start", "completed", or "measuring". If the measurement state is "waiting for start" or "completed" (S120: waiting for start or completed), this process is terminated. On the other hand, when the measurement state is "measuring" (S120: measuring), the process proceeds to S130. In S130, it is determined whether or not the number of overflow occurrences has reached the specified number of times. This specified number of times is set to 16. The fact that the overflow occurs 16 times means that the fall of the pulse is not input for a long time of about 400 ms, and in such a case, it is necessary to exit the "measuring" state. .. If the number of overflow occurrences has not reached the specified number (S130: No), the counter overflow interrupt processing 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 the 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 processing is terminated. On the other hand, if the number of recorded data does not exceed the specified number (S140: No), the process proceeds to S160, the measurement state is changed to "error" in S160, and this interrupt processing is terminated.

By such processing, the number of overflow occurrences is counted when an overflow occurs, and if an abnormal condition such as the number of overflow occurrences of 16 occurs, the measurement is stopped there and the recorded data exceeds the specified number. Changes the measurement status to "Complete" and performs the speed calculation process described later, while if the recorded data does not exceed the specified number, the measurement status is changed to "Error" and the accumulated data is discarded. Then, a process (not shown) is performed to return to the "waiting for start" state.

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

When the first microcontroller 724 detects the falling edge of the Doppler pulse, it starts the falling interrupt processing of the Doppler pulse shown in FIGS. 42 and 43. First, in S310, it is determined whether the measurement state is "waiting for start", "completed", or "measuring". In the case of "waiting for start", the process proceeds to (S310: waiting for start) S320, in the case of "completed", the process proceeds to (S310: completed) S440, and in the case of "measuring", the process proceeds to S360.

In S320, it is determined whether or not the period is smaller than the specified value. As a 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. That is, specifically, it is determined whether or not the value of the capture register 724c is smaller than this specified value. If the cycle is smaller than the specified value (count value is smaller than 776 times) (S320: Yes), the process shifts to S330, and if the cycle is greater than or equal to the specified value (count value is 776 times or more), (S320: Yes). S320: No), shift to S440. In S330, it is determined whether or not the number of overflow occurrences is 0. If it is 0 (S330: Yes), it shifts to S332, and if it is not 0 (non-zero) (S330: No), it shifts to S440.

In S332, C is incremented by "+1", and in S334, it is determined whether or not the incremented new value of C is 4. If the value of C is not 4, that is, from 1 to 3 (S334: No), the process proceeds to S440, and if the value of C is 4, the value is reset to C = 0 (S336), and then the process proceeds to S338. In S338, the first microcontroller 724 outputs a storage start signal to the second microcontroller 725. In other words, when the cycle is smaller than the measured value (S320 is Yes) and overflow has not occurred (S330 is Yes) four times, it can be determined that the swing has been performed, and the above accumulation start signal is displayed. Output. The function of executing the processing steps of S320 to S338 constitutes the swing determination means.

This swing discriminating means determines that the head has swung when the cycle of the Doppler signal based on the Doppler signal output by the Doppler sensor has a cycle pattern corresponding to the swing of the head (finally Yes in S334). is doing. The periodic pattern corresponding to the swing of the head is determined in advance based on the periodic pattern obtained by swinging various clubs by a large number of people in advance and the periodic pattern obtained when the club is not swinging. Alternatively, for example, the periodic pattern corresponding to the swing of the user may be learned and used.

After outputting this accumulation start signal, the first microcontroller 724 shifts to S340. In this S340, the measurement state is changed to "measuring" and the process shifts to S350. In S350, the number of falling falls stored in the memory 724b is changed to 0. In this way, when the period of the Doppler signal output by the Doppler sensor 721 becomes smaller than the predetermined value, the setting to start the accumulation of the period data in the memory 724b is performed. Therefore, in the next interrupt process at the fall of the Doppler pulse, it is determined in S310 that "measurement is in progress", and the process after S360 is performed.

In S360, the number of falling falls stored in the memory is incremented by 1. In the following S370, it is determined whether or not the number of overflow occurrences is 0. If the number of overflow occurrences is 0, the process proceeds to (S370: Yes) S400, and if the number of overflow occurrences is not 0, the process proceeds to (S370: No) S380.

Since the counter 21 is 16 bits, an overflow interrupt is generated when the count value exceeds 65535, and the overflow occurrence number is incremented by the overflow interrupt process (S110). Since the count value 65535 corresponds to about 26 ms and is sufficiently longer than the value (cycle) to be measured, it is determined that if an overflow occurs, it is not necessary to record this cycle data.

In S380, it is determined whether or not the period is smaller than the 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, which is the same as the specified value of S320. If the cycle is smaller than the specified value (count value is smaller than 776 times) (S380: Yes), the system shifts to S390, and if the cycle is greater than or equal to the specified value (count value is 776 times or more), (S380: Yes). S380: No), shift 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 the previously recorded data, it is recorded in the area next to the area in the previously stored array), and the data is transferred to S400.

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

In S410, it is determined whether or not the number of recorded data in the array on the memory 22 exceeds the specified number, and if it exceeds the specified number (S410: Yes), the process proceeds to S420, and in S420. , Change the measurement status to "Complete" and end this interrupt processing. On the other hand, if the specified number is not exceeded (S410: No), the process proceeds to S430, the measurement state is changed to "error" in S430, and this interrupt processing 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 processing of S370 (S370: Yes) or when the period is determined to be equal to or higher than the specified value in S380 (S380: No), the processing of S390 is not performed and the periodic data. Since the data is not recorded in the array (memory 22), the number of recorded data may be less than 110. In this case, the number required for the speed calculation process in FIG. 9, which will be described later, is set to 32. If the number exceeds this number (S410: Yes), the measurement state is set to "complete" and the speed calculation process is performed. If the number does not exceed this number (S410: No), the measurement status is changed to "error", the accumulated data is discarded, and the process returns to the "waiting for start" status. Let me do it.

By the Doppler pulse fall detection interrupt processing as described above, when the measurement state is "completed", 33 or more data related to the cycle for which the velocity is calculated will be accumulated in the memory (array) 724b. ..

Next, the speed calculation process will be described with reference to FIG. 44. The speed calculation process starts when the measurement state becomes "completed".

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

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

Specifically, in S520, first, the value of n is set to 12.5%, and if all four original data are not within the range of the average value ± 12.5%, the data has a large variation. Assuming that, the exclusion flag is set for the moving average value calculated from the original data. The exclusion flag allocates a 1-bit memory area for one moving average period data in a format corresponding to, for example, a moving average storage array.

In the following S530, if the number of data (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 then the process proceeds to S540. ..

In S540, the value of n is set to 25% this time, and if all four original data are not within the range of the average value ± 25%, the data is regarded as data with large variation and calculated from the original data. Set the exclusion flag for the moved average value.

In the following S550, as a result of the exclusion process in S520, it is determined whether or not the data (number of valid data) for which the exclusion flag is not set is less than 10, and if it is less than 10, (S550: Yes), the process proceeds to S560. Transition. In S560, the measurement state is set to "error" and this process is terminated. 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. Further, in S530, even 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.

（ｖ：ヘッド速度、ｃ：光速(299792485m/s)、fb：カウンタの基準パルス周波数、f0：マイクロ波ドップラーセンサ出力周波数(24.15GHz)、nmin：最小周期データの値） In S570, the minimum period data (minimum value of period = maximum value of frequency = corresponding to maximum speed) is searched from the moving average period data in which the exclusion flag is not set. In the following S580, the velocity (head speed) is calculated from the minimum period data obtained in S570. The speed is calculated based on the following (Equation 1).

(V: Head speed, c: Light speed (299792485m / s), fb: Counter reference pulse frequency, f0: Microwave Doppler sensor output frequency (24.15GHz), nmin: Minimum cycle data value)

In the following 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 head speed display is blinked for 10 seconds from the start of the display. When the blinking display process for 10 seconds is completed, the head speed obtained in S580 is set as a lighting display, and the process shifts to S600.

In the following S600, the measurement state is changed to "waiting 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. Then, in that state, the golfer swings the golf club. At this time, the ball may be teeed up to actually hit the ball, or the ball may be swung without being set.

When the head of the golf club enters the detection range of the Doppler sensor 721 with the swing, a Doppler pulse with a cycle corresponding to the movement speed of the head 2 is input to the first microcontroller 724, and the data of each cycle is stored in the memory based on the input. It accumulates in 724b and then the maximum speed is measured. Then, when the measurement is performed correctly, the obtained 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, by looking at the display screen 711 after the swing, the user can know whether or not the speed can be measured and, if the speed can be measured, whether or not the speed is displayed in a blinking state.

Next, the function of the second microcontroller 725 will be described. When the second microcontroller 725 receives the storage start signal from the first microcontroller 724 with the execution of S338, the second microcontroller 725 incorporates the Doppler signal (amplified signal) output from the amplifier 722 into the second microcontroller 725. It is converted into a digital signal by the A / D converter, and is taken in and stored in the built-in memory (RAM) for 160 ms. When the acquisition is completed, the stored data in the memory is calculated by FFT to calculate the speed. As a method of 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.

That is, 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 in the vicinity of before and after hitting the ball, and then gradually decreases. On the other hand, at the beginning of the swing of the golf club, the moving speed of the ball is 0 because the ball remains stopped, and the speed is increased because the ball moves when the head hits and launches the ball. Then, there is a discrepancy 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, after the swing determination means (processing algorithm that executes S320 to S328) detects the golf swing and the first microcontroller 724 outputs the accumulation start signal, the second microcontroller 725 determines the ball speed. The Doppler signal (signal amplified by the amplifier 722) required for the calculation is recorded.

Thereby, the head speed is calculated based on the data group accumulating the data regarding the period of the Doppler signal based on the Doppler signal output by the Doppler sensor, while the ball speed is calculated based on the Doppler signal output by the Doppler sensor. It is calculated based on the A / D conversion data group in which the / D conversion data is accumulated. By separating the speed of the head and the speed of the ball in this way, both the head speed and the ball speed can be accurately measured.

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

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

For the estimated flight distance, when the ball is actually hit, the flight distance is obtained from the ball speed and the club type used, and in the case of swinging, the flight distance is obtained from the head speed and the club type used. 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 the club type-coefficient is provided), and the 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 or absence of the ball may be manually specified by manual operation, or various sensors may be provided and the device may automatically recognize the presence or absence of the ball.

In this embodiment, the speed is calculated based on the data for each cycle, the data that may be erroneously detected is discarded, and the speed is finally obtained based on the remaining reliable data. Therefore, the displayed speed will be accurate without being affected by the surrounding conditions. In addition, when the head speed is measured with the ball actually hit, the ball pops out vigorously after impact, so the moving speed of the ball is sufficiently higher than the head speed, and the output of the Doppler sensor 721 is The number of waves of the Doppler signal generated during the distance from the head of the golf club entering the detection range of the Doppler sensor 721 to the position where it is expected to impact the ball, which may be based on the movement of the ball. Since the configuration is such that the periodic data is stored in the memory 724b only for the specified number of 110 times corresponding to the above, the swing speed can be measured correctly 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 the "practice mode". In addition to being used for display, the "meat rate" displays the "nice shot animation" in the "swing mode" by comparing and judging the magnitude with the set "meat rate reference value (1.40 in the initial setting)". It is reflected in whether or not, and the "estimated flight distance" is reflected in whether or not the "nice on animation" is displayed by making a comparison judgment with the "target setting distance" and "green radius" set in the "practice mode". Will be done.

The arithmetic processing in the trainer device 710 is also executed in the "Arc mode". Therefore, after confirming the swing trajectory or the like on the screen in the "Arc mode", the "head speed" or the like in the current swing can be referred to by returning to the menu screen and touching the "swing". In "Arc mode", as a result of "model display", the swing trajectory is corrected to match the swing trajectory of "model", and the "head speed" etc. at that time is confirmed by the display of "swing mode". By doing so, it is useful for training to increase the flight distance with a compact swing. The measurement of the swing trajectory in the "Arc mode" includes the measured values of the 3-axis speed and the 3-axis angular velocity transmitted from the motion sensor 730 at intervals of 2 ms, and the calibration result of the sensor mounting position and 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 the position information at predetermined time intervals 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 calculated accurately.

Also, if the motion sensor 730 is attached to the club, the power is turned on, and the "swing mode" is executed while the LED lamp 732 is continuously lit in green, the "head speed" etc. for this swing is confirmed. After that, if you return to the menu screen and touch "Arc", you can check the swing trajectory, face trajectory, and swing data in this swing.

This also applies when the operation of switching the display screen between the "practice mode" and the "Arc mode" is performed.

As described above, according to this 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, and the "meet" can be calculated. Not only can the "rate" be detected accurately, but also 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 "model display", the user can accurately and accurately provide information to be referred to when training so that a more accurate swing can be performed at a more appropriate head speed.

In this embodiment, measurement of "head speed" and "ball speed", calculation of "estimated flight distance" and "meet rate", calculation of "swing trajectory", "face trajectory" and "swing data", notification to the motion sensor 730. Various arithmetic processes such as control related to communication, detection of switch operations such as screen switching by touching the display screen, and display screen switching are performed by a computer program installed in advance in the ROM of the microcontroller 724,725 of the trainer device main body 710. It has been realized. This computer program itself may be uploaded to a server or the like as a downloadable application, and downloaded and installed on the trainer device main body 710 using the Bluetooth wireless communication function, or installed on various types of terminal devices and personal computers. It may be used as a configuration.

Further, the first microcontroller 724 and the second microcontroller 725 of the trainer device main body 710 in this embodiment may be configured by one controller. On the contrary, a speed detection device provided with a microwave Doppler sensor 721 and a separate third arithmetic processing device (for example, a mobile communication terminal) are provided, and a motion sensor 730 is attached to a golf club as in the present embodiment, and the speed is increased. The detection device is installed under the same installation conditions as the trainer device 710 in this embodiment, 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 is used. 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 speed detection device may perform calculations and transmit the calculation results to the mobile terminal device. As an internal process of the mobile terminal device, the menu screen may be displayed, the display screen may be switched, or the setting may be changed.

According to each of the above-described embodiments, the pulling force generated on the fasteners (rubber band 20, rubber rings 120, 220, mounting belt 750) on the rod-shaped portion (shaft 3a) of the object (golf club 3) is an object. (Golf swing sensor 1,101,201,301,401,501,601, motion sensor 730) can be easily attached.

Although the examples for carrying out the invention have been described above, the present invention is not limited to these, and various modifications can be made without departing from the gist thereof.

For example, it may be adopted as a mounting structure for mounting a sensor on a shaft of a tennis racket, a baseball bat, a spear for throwing, a frame of a bicycle, a propeller shaft of an automobile engine, a conrod, or the like. Further, it can be used as a mounting structure for mounting an object other than the sensor, or can be applied to a mounting structure for mounting a sensor holder for mounting the sensor.

At the time of mounting, a non-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 rubber band with a hole, a rubber string provided with a ring, or the like may be adopted, and the material may be a synthetic resin other than rubber, a coil spring, or the like.

A mushroom-shaped pin may be used as a holding hook to prevent the housing from coming off, or a slit formed so as to cut from the front side of the housing may be used. In the type of the third embodiment, the temporary hooking portion may be formed by a mushroom-shaped pin instead of the hook. It may be configured to have a hooked claw.

In the type of Example 1, the number of openings may be 4 or more, or vice versa.

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

Further, in the first embodiment, the battery storage structure of the fourth embodiment may be adopted, or the terminal cover may be wrapped around to the shaft side and attached as in the fifth embodiment.

As shown in FIGS. 45 (A) and 45 (B), the attachment belt 750 may be used for the golf swing sensor 1 of the first embodiment which is not provided with the sponge body. Also at this time, as shown in the figure (A), not only is it used for the part that hooks on the hook part of the sensor body during normal use, but in the state of the figure (A), the fixing to the shaft is weak and the sensor body moves. In this case, as shown in the figure (B), by hooking this part on the hook part of the sensor body, the length of the rubber band used for tightening is shortened, and the sensor body is fixed to the shaft with a stronger force. Therefore, the sensor body becomes difficult to move. In this case, as described above, in the mounting belt 750, by creating a plurality of places for hooking the hook portion, two types of fixing methods (more if the number of hooking places are increased) can be made with one type of rubber band. It is cheaper than attaching a type of rubber band. In addition, the method of changing the hooking place with one rubber band is simpler, easier to understand, and less troublesome than selecting and using a plurality of rubber bands having similar shapes and different lengths. In the method (B) shown in the figure, a large force is required to hook the rubber band to the hook portion on the opposite side. If you want to fix the sensor body weaker than the method shown in the figure (B) and stronger than the method shown in the figure (A), the rubber tube 800 (with a cut on one side) as shown in FIG. 45 (C). ) Is fitted to the shaft and the sensor body is stopped from above, so that the amount of stretching the rubber band increases, so that the rubber band 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 contains a cut 801 and may be attached to the shaft 3a by opening the cut 801.

Here, in the modified example of FIG. 45 (C), the rubber tube 800 has an inner diameter of 12 mm or less, and has a dimension such that the cut 801 is 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 is made of synthetic rubber which is black in terms of the color of the material. Is superior to silicone rubber, which is basically white. It is preferable to use a rubber tube 800 having a wall thickness of about 3 mm.

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

Further, the golf swing trainer system 700 of 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 mounting belt 750 described in the eighth embodiment.

In Example 8, it is preferable to attach the silicon gel sheet to the entire surface of the sponge body 737 located on the golf club side with double-sided tape. The surface of the silicon gel sheet is less slippery than the sponge body 737, and the silicon gel sheet can be further 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 the thickness of the sponge body of 5 mm. This is because the silicon gel sheet has a weaker repulsive force than the sponge body 737 when compressed, for example, the pressed portion remains compressed and the surface of the silicon gel sheet becomes uneven, for example, and the adhesion is lowered. Because it will be stored.
As described above, the surface of the golf club in contact with the shaft side is provided with a first member (silicon gel sheet in the above example) which is made of a material having a relatively weak surface slip and a weak repulsive force and has a thin wall thickness. A configuration is provided with a second member (sponge body 737 in the above example) which is made of a material having a relatively strong repulsive force and a thick wall on the side away from the shaft, which is relatively prone to surface slippage. It is good to say.

The present invention can be used in various industries as a structure for attaching an object to a rod-shaped portion of an object. It can also be used as a practice system for golf and the like.
