Golf Classic March 2013 (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 determine the swing trajectory. Analysis is performed.

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, there is a problem that the trainer function is not sufficient because only a rough estimation calculation using the acceleration data, etc., can be performed.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to improve the accuracy of information to be provided to users.

The system of the present invention, which has been made to achieve the above objects, (A) acquires the data necessary to identify the trajectory and speed of the swing, and performs processing for calculating and reporting information on the trajectory and speed of the swing. Arithmetic processing means is provided, and each data is obtained separately by separate detection means.

According to the system of the present invention, the data necessary for identifying the trajectory of the swing and the data necessary for identifying the speed of the swing are obtained separately by separate detecting means, and based on these data, the arithmetic processing means calculates the swing speed. Calculating and announcing information on the trajectory and speed of the As a result, highly accurate information calculated based on the measured values is obtained. For example, in a conventional configuration in which the velocity is determined from the trajectory of the swing, the determined velocity is merely an estimated velocity of the swing, resulting in poor accuracy. Can also be configured.

The system of the present invention further comprises: (B) the arithmetic processing means acquires data corresponding to the same swing from each of the detection means, It is preferable to have a configuration that it is configured as a means for calculating information related to.

Information on the trajectory and speed of the swing when an object is swung once can be calculated with high accuracy, and by notifying based on the results of the calculation, it is possible to make a single swing from both the viewpoint of the trajectory and the viewpoint of speed. It is possible to give the user an opportunity to analyze and consider the swing of the player. The "thing" to be swung may be, for example, a part of a machine or a part of the body of a person or an animal, but it is particularly preferable to use a tool. The equipment may be equipment that a person swings with his/her body, especially sports equipment.

In these systems of the present invention, (C) the detection means for acquiring the data necessary for specifying the trajectory of the swing is attached to the object to be swung, and the detection means for acquiring the data required for specifying the speed of the swing is It is good to adopt the composition of installing in another place other than the above-mentioned thing.

The swing trajectory of an object can be directly detected by attaching a detection means for acquiring the data necessary for specifying the swing trajectory to the object, and the detection means for acquiring the data required for specifying the speed of the swing is provided. By installing it in an appropriate location other than the above, it is possible to objectively and accurately grasp the speed of movement of the object from the outside, and as a result, it is possible to accurately detect the trajectory and speed of the swing. In particular, the "another appropriate location" may be, for example, a location that does not move at least with a swing, and preferably a location 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) Based on the acquired data, the arithmetic processing means determines whether or not the object is in a ready state for starting a swing, and performs control for notification.
(E) The arithmetic processing means performs control for judging whether or not the object has finished swinging based on the acquired data and notifying the same.

By providing such a configuration, it is possible to notify the swing detecting means attached to the object that the object has been prepared for starting the swing or that the swing has been completed.

In these cases, it is preferable to further provide a configuration of (F) performing the notification from a portion attached to the object to be swung.

The swing detection means that receives the above-mentioned notification performs a display based on the notification, so that the user who is about to swing the object can be accurately notified as to whether or not it is permissible to start swinging. measurements, etc., can be performed. As a result, the accuracy of detection is also improved.

Further, in these systems of the present invention, (G) the arithmetic processing means can cause the display means to distinguish overlapping trajectories from the start of the swing to the end of the swing as the processing for notification. It is also preferable to perform a process of displaying information about the trajectory of the swing in a display mode.

For example, in golf swing practice, one swing consists of an upswing and a downswing of the club, and their trajectories overlap. In such a case, the user can accurately determine whether there is a point to be corrected in the upswing or the downswing by adopting a display mode in which the overlapping can be distinguished. Become.

More specifically, it can be configured as in (G1) to (G3) below.
(G1) 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 as the display mode.
(G2) As the display mode, the arithmetic processing means performs a process of changing the display color on the boundary of the inflection point of the trajectory from the start of the swing to the end of the swing.
(G3) The arithmetic processing means performs processing for displaying, as the display mode, a moving image of a trajectory from the start of the swing to the end of the swing.

According to the configurations of (G1) and (G2), when the entire swing trajectory is displayed, it is possible to easily understand which one is the trajectory immediately after the start of the swing from the difference in color in the overlapping portion. According to the configuration of (G3), by displaying the trajectory of the swing as a moving image, for example, an upswing and a downswing in golf can be distinguished. It should be noted that the configuration of (G3) may be adopted together with the configurations of (G1) and (G2). In this case, the overlap can be distinguished from the entire drawn trajectory while feeling the change in the trajectory during the reproduction of the moving image, and information can be conveyed to the user in a more comprehensible manner.

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

By adopting such a configuration, it is possible to effectively use the screen size of the display means to display the swing trajectory. For example, in the case of golf swing practice, if the ball is displayed in the center of the screen, the overall swing trajectory will be displayed in a small size. , the swing trajectory can be drawn large.

In the system provided with display means, further, (J) the data necessary for specifying the trajectory of the swing is acquired at a sampling interval of 2 ms or less; On the other hand, it is also preferable to employ a configuration in which the trajectory is displayed in a display mode that represents continuous changes in position corresponding to the sampling interval.

For example, taking a golf swing practice as an example, the lowest point of the swing trajectory is the position for hitting the ball. In this case, when the sampling interval from the swing detection means is about 5 ms, the lowest point position cannot be captured with high accuracy, whereas the detection signal from the swing detection means is generated at a sampling interval of 2 ms or less, more preferably 1 ms or less. is obtained, the accuracy of capturing the lowest point position is increased, and it becomes possible to more accurately convey to the user the trajectory of the swing at the moment of impact.

By doing so, it is possible to facilitate the attachment work when attaching the object to the bar-shaped portion of the object by the tensile force generated in the fastener. For example, it is easy to turn the back of the rod-shaped portion of the fastener, and when the back of the rod-shaped portion is turned and the fastener is pulled, the object is less likely to shift from the rod-shaped portion. The work of hooking on the part can be facilitated.

In the "structure in which the rod-shaped part of the object is sandwiched between the object body and the fastener", the object body and the fastener are not limited to the form in which the object body and the fastener directly abut against the rod-shaped part. A form in which some kind of inclusion such as a non-slip sheet is sandwiched may be adopted, or a form in which some kind of inclusion is sandwiched between the fastener and the rod-shaped portion may be adopted. A configuration in which an inclusion is sandwiched between both the main body and the fastener may be adopted.

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

"Objects" and "bars" include, for example, golf club shafts, tennis racket shafts, baseball bats, spear throwing spears, bicycle frames, propeller shafts and connecting rods of automobile engines, etc. be able to.

Examples of the "fastener having a hanging ring" include a rubber ring, a perforated band rubber, and a rubber cord having a ring. The material is not limited to rubber, and may be synthetic resin, coil springs, or the like.

Examples of the "hanging part" include a hook-shaped hook, a mushroom-shaped pin, etc., which are provided so as to abut against the object body, and a slit formed by cutting the object body from the front side. can.

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

Furthermore, as the "stretching force reduction structure that can be provided for the latch", there are provision of provisional hooks that protrude in a direction other than the stretching direction of the fastener, and rotation of the latch from the rear to the front. It can be provided with a lever or slider that can be moved or slid for temporary hanging. In this case, the lever or slider may be manually operated or electrically operated.

In addition, as the "stretching force reducing structure that can be provided in both the fastener and the latching part", for example, the number of hooks is increased, and the number of holes in the perforated rubber band is increased accordingly. reducing the area of the cross section that supports the tensile force of

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

By providing the configuration (2), when attaching an object, it is only necessary to pull the fastener to the extent that it is temporarily hung on the temporary hanging part, and the stretching force when hooking the fastener can be reliably reduced. The work of stretching the fastener after it has been temporarily hung can be easily performed because the temporarily hung part can be used as a fulcrum.

For example, it is preferable to set the relationship between the temporary hooking portion and the real hooking portion so that the stretching force is smaller in the temporarily hooked state than in the fully hooked state. In this case, ``the temporary hanging part has a structure that pulls and hangs in a direction different from the direction in which the force is applied to the real hanging part'', or ``the temporary hanging part has a structure in which it is in the real hanging state "placed at a position closer to the pulling direction", or "the actual hooking state is a state in which a plurality of parts are hooked, and the temporary hooking state is a state in which one part is hooked".

In this case, 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 in a direction intersecting with the direction in which the fastener is routed is provided in a part of the hooking portion.

Here, the direction of the pulling force to be applied to the fastener to sandwich the rod-shaped portion of the object between itself and the object body is the direction in which the fastener is routed. By providing the configuration (3), the fastener can be pulled in a direction other than the direction in which the fastener should generate a tensile force for sandwiching the rod-shaped portion between the object body and the fastener when the fastener is temporarily hung. It is only necessary to pull it, and it becomes possible to easily perform the temporary hooking work. In addition, the direction in which the fastener is pulled in order to finish hooking the fastener to the latching portion after temporary hooking is also the direction in which the fastener should generate a tensile force for sandwiching the rod-shaped portion between the object body and the fastener. They do not have to match each other, and the temporary hooking claw forms a bent portion in the stretching operation, so that the stretching operation can be easily performed until the hooking is finished.

In this case, configuration (3) may be embodied as follows.
(4) As the temporary hooking portion, the hooking portion is provided with a first axial hook portion toward one end of the shaft and a second hook portion toward the other end of the shaft along the axial direction of the bar-shaped portion. 2 axial hooking claws

By adopting configuration (4), after the hanging ring portion of the fastener is pulled so as to expand in the axial direction of the rod-shaped portion and is temporarily attached to one of the axial hanging claw portions, it is pulled toward the axial hanging claw portion on the opposite side. Moreover, when the fastener is hooked on the opposite axial hook, the fastener is firmly hooked between the axial hooks. In spite of the fact that the work up to temporary hooking and the work up to the completion of hooking are easy, the fastener is firmly hooked so as not to come off carelessly. In this way, the effect of reducing the stretching force in the stretching operation when hooking the fastener is exhibited more reliably. As a result, for example, there is no need to use a thick rubber band, and the need for the latching portion to protrude greatly to the side is also eliminated, and the effect of reducing the outer size of the object is exhibited.

In the configuration (4), for example, instead of attaching a wall extending to the front side to the latching portion to prevent the fastener from coming off, a protrusion is added in the vertical direction (the axial direction of the rod-shaped portion) to prevent the fastener from coming off. It is preferable to reduce the amount of tension on the fastener to reduce the mounting force.

In this case, it is preferable to have the following configuration.
(5) Between the axial hanging hook portions, a gap is provided to the extent that a finger can pass through.

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

Configuration (2) may also be embodied as follows.
(6) The stretching force reducing structure is movable between a temporary hanging position and a permanent hanging position, and at least during movement from the temporary hanging position to the permanent hanging position, the hanging ring portion of the fastener is hooked. Equipped with mobility assistance means that can

At the temporary hanging position, the hanging ring portion of the fastener is temporarily hung on the moving force assisting means, and then the moving force assisting means is moved to the actual hanging position.

The moving force assisting means may be of a manual type or an electric type, and may be of a rotating lever type or a sliding type as long as it can be moved from the temporary hanging position to the actual hanging position.

For example, "(6A) As the stretching force reducing structure, the bar-shaped portion of the latching portion is placed at an intermediate position in the axial direction between a tilted position tilted to the back side and a raised position tilted to the front side. and a rotating member capable of temporarily engaging the hanging ring portion at the collapsed position.".

When the configuration (6A) is provided, the fastener is temporarily attached to the rotating member in a state in which the rotating member is laid down to the collapsed position. First, the fastener is temporarily attached to the rotating member. Temporary attachment of the fastener to the rotating member that is laid down on the back side can be performed without stretching the member strongly. After the temporary hanging is completed, the rotating member can be lifted up to allow the fastener to be stretched with less force using the principle of leverage. become a thing. Even when this configuration (6) is adopted, it is not necessary to use a thick rubber band to make it easy to pick up.

The pivoting member can be constituted by a lever attached to the object. In addition, the fastener does not have a special thickness shape, but a general-purpose O-ring. When this O-ring is hooked on the lever and the lever is raised, the main body can be attached to the shaft of a golf club, etc., by the principle of leverage with little force. can be attached to the bar of the In addition, in the case of the above mounting method, the rubber had a special shape, but in this case, a rubber component with a simple shape such as an O-ring can be used. Parts and structures are required to prevent the lever from coming off due to force applied to the lever when attached to a golf club or the like, which may increase the number of parts and complicate the structure.

These object mounting structures of the present invention may further include the following configuration.
(7) The fastener is composed of an elastic ring-shaped member closed as a whole, at least a part of which is provided with an insertion opening having a dimension smaller than the cross-sectional dimension of the elastic ring-shaped member, and located at both axial ends of the rod-shaped portion. The object is provided with a retaining portion for preventing detachment corresponding to the latching portion.

By adopting the configuration (7), it is possible to perform the hooking work in a state in which the fastener is firmly pulled vertically and horizontally in parallel using the temporarily hooked state, and the mounting state of the object becomes more stable. . In order to achieve such a stable tensioning state, it is possible to complete the work of hooking the fastener by using the principle of leverage from the temporarily hung state or by stretching in the axial direction that is not the final pulling direction. As a result, it is possible to exert a sufficient pulling force even when using a relatively small diameter, and to make the attachment of the object robust. As a result, for example, it becomes possible to implement the present invention using a general-purpose O-ring as a fastener.

Also, 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 latching portion is composed of the composite ring-shaped member. The free end side of each opening of the member is composed of a plurality of hook portions that can be hooked as hook loop portions.

As a specific example of the configuration (8), for example, it is possible to imagine a fastener that is made by integrating a plurality of rubber bands. The fastener can be hooked in a state in which a firm pulling force is generated even if it is made thinner. By reducing the diameter of each part, the stretching force during hooking work is reduced. Also, even if one of the wires breaks, the object will not fall off because the hooked state will not be released.

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 latch portion has a comb-shaped structure having three or more hook portions. to be

As a specific example of the configuration (9), there are four or more parts that exert a tensile force. As a result, even if one is broken, the remaining three can be used to firmly maintain the attached state. As a result, if the fastener is made of rubber parts, it can be made thinner. This is the result of the fact that the number of parts exerting a pulling force is four or more, and the role of a safety device is firmly fulfilled. And, as a result of being able to make it thinner, it is possible to reduce the outer dimensions of the fastener. As a result, the overall object can be small and compact.

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

By also providing the configuration (10), the compression deformation of the abutting member on the back surface of the object strengthens the clamping against the rod-like portion, and pressure contact due to friction in the mounting state can be expected, and the mounting state is further stabilized. . This contact member also functions as a non-slip.

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

By also providing configuration (10), the object can be more stably attached to the object. For example, the shaft of a golf club is tapered from the grip toward the head, or tapered with a step. Baseball bats gradually thicken from the grip to the tip. In configuration (10), for example, the rubber applied to the club is also inclined according to the inclination of the shaft so as to correspond to the shaft of the golf club. It is. For example, the contact member may have an inclined surface or a stepped surface corresponding to the shape of the outer surface on the back side. With this configuration, when the rod-shaped portion has a tapered or stepped outer surface shape whose diameter varies depending on the position in the axial direction, compression deformation of the contact member on the back surface of the object causes contact between the object and the object. To maintain high adhesion even when the diameter of such a rod-shaped portion changes in the axial direction by enhancing adhesion and forming the back side of the contact member as an inclined surface or a stepped surface. Therefore, it is possible to prevent an object from being attached at a slant or an unstable attachment state such as a gap at the lower end side, for example.

When these contact members are provided, it is preferable to further provide the following configuration.
(12) The contact member is detachably attached to the object.

The abutment member has the effect of increasing 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 abutment portion, there is a risk of an unstable mounting state with a gap. This is because the configuration (12) can be used to replace the abutment member with a back surface corresponding to the outer diameter and taper angle of the rod-shaped portion of the object. By providing a structure in which the non-slip abutting member can be easily removed, for example, a battery can be placed in the portion where the abutting member is attached so that the battery can be replaced. Further, for example, it is possible to prepare a rubber abutment member suitable for each type of golf club and replace it to improve the anti-slip effect when attaching an object.

When such a detachable abutment member is provided, it is preferable to further provide the following configuration.
(13) The contact member is configured such that the amount of compressive deformation increases outward from the axial center of the rod-like portion.

The abutting member is different from a simple plate-shaped rubber pasted on the back of the object. As a result of the contact member being compressed and deformed more strongly on both end sides, a strong adhesion force is generated.

In this case, it is preferable to further include the following configuration.
(13A) The contact member is composed of an elastic member having a cross-sectional shape having a flat surface on the front side and a recessed surface on the back side, and a frame-shaped rib projecting toward the front is formed around the flat surface. wherein the object has 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 when the compressive deformation is performed; detachably accommodates parts thicker than the height of the frame-shaped part of the

With the configuration (13A), the frame-shaped ribs of the abutting member abut against the frame-shaped portion on the housing side at positions close to both ends of the fastener, and the abutting member is relatively thick in this portion. The amount of compressive deformation increases by 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 will not be damaged by the pressure. When taking out the inner part, the back surface of the part has an edge protruding toward the back side from the frame-shaped part of the housing, and the part can be easily removed by putting a finger on the edge.

These object mounting structures of the present invention preferably have the following configurations.
(14) The object is a moving object used to swing around, and the object is an electronic device having an electronic circuit built in a housing or a fixture for mounting an electronic device having an electronic circuit built into the housing. .

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

The object should preferably be an object to which a force is applied to separate the object attached to the rod-shaped portion of the object from the rod-shaped portion of the object during normal use of the object.

It is preferable that the target object is an object whose part is grasped and moved by a person. In particular, it should be exercise. In particular, a grip may be provided as a part to be gripped, and the grip may be gripped and swung around for exercise. Examples of exercise objects that are gripped and swung around include golf clubs, tennis rackets, and baseball bats. A method of detecting the state of a swing with a swing sensor or the like is advantageous for acquiring higher skills using these exercise objects. In this case, there is also a method of photographing the swinging state of these moving objects with a camera from the side and analyzing and analyzing the images, but in that case, photography technology is required. On the other hand, if a sensor is attached directly to these moving objects, such a high imaging technique is not required. On the other hand, if the mounting state of the sensor directly attached to the moving object is unstable, accurate detection cannot be performed. In this respect, the object mounting structure of the present invention facilitates the mounting work of the object, so that the object can be mounted in an appropriate position in a stable state, so swing detection with sufficiently improved accuracy is possible. do.

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

When the configuration (15) is adopted, when consciously operating the power switch of the electronic device attached to the exercise object, this can be easily performed while holding the grip, and the on/off operation can be performed as intended. It is possible to easily confirm whether or not the display is in the state while holding the grip, and there is also an effect that it is easy to see. On the other hand, if the user does not intentionally operate the switch, the rod-shaped part will interfere and the switch will inadvertently touch the body such as the thigh or other surrounding objects (simply referred to as "the thigh" in this specification). There is no need to turn on or off a switch against your will.

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

In configuration (16), when the electronic device is attached to a moving object, the handle of the terminal cover faces the rod-like portion, and the terminal cover may unintentionally come into contact with the thigh and the terminal cover may open. because there is no For example, by making it difficult to open the terminal cover when attached to a golf club, it is possible to prevent the cover from opening due to accidental contact of the main body with something.

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

This is because, by providing the configuration (17) as well, the terminal cover cannot be opened in an object-attached state, but the problem of inadvertent opening can be almost completely avoided.

Moreover, the object mounting structure of the present invention may further include the following configuration.
(18) The object is an electronic device in which an abutment member that is compressed and deformed by the tensile force of the fastener is detachably attached to the object from the back side of the object, and the object is an electronic device in which an electronic circuit is built in a housing. A replaceable part is housed in the casing in such a manner that its circuit portion is positioned on the rod-shaped portion in a state of being movable in the axial direction of the rod-shaped portion.

In this case, it is preferable to further include the following configuration.
(18A) The replacement part includes a part with a relatively high breakability on one axial end side of the rod-shaped portion and a part with a relatively low breakability on the other axial end side of the rod-shaped portion. 2. storing the replaceable parts such that the relatively breakable parts are located on the opposite side of the direction of the forces to which the object is subject to movement;

In this case, it is preferable to further include the following configuration.
(18B) The replaceable part is a battery, and the battery comprises a substrate as the relatively fragile part.

When the object is swung around the rod, centrifugal force is generated outward from the rotation center of the rod, and when the object is moved in the axial direction of the rod, inertia is generated in the direction opposite to the moving direction. Forces are generated, but due to the above configuration, the circuit parts of replacement parts and parts with a relatively high possibility of destruction are located on the opposite side of the direction in which these forces act, so important circuit parts can be removed from the housing. never be hit by For example, when a swing sensor is attached to a golf club as an object, centrifugal force acts in the direction of the head when the club is swung. For example, even if there is a component that is loosely housed in a way that is movable in the axial direction inside the housing, the important circuit portion of the component will not hit the housing. As a result, for example, even if a replacement part such as a battery is easily replaced and accommodated in the housing, damage to the replacement part can be avoided.

In this case, it is preferable to further include the following configuration.
(19) The replaceable part is a battery, and the lead wires connected to the circuit part are accommodated together with the lead wires in a gap having a width that allows them to be positioned to the side of the battery.

In the configuration (19), the lead wire is intentionally lengthened to protect the circuit part on the battery side. There is no chance of being pinched and damaged.

It should be noted that the object mounting structure of the present invention may further include the following configuration.
(20) The object is an exercise device that is used by gripping and swinging a grip, the object is an electronic device containing a plurality of circuit boards connected by a board-to-board connector in a housing, and the housing is an electronic device. The front-side housing is composed of a back-side housing for fixing the 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 formed with a rib so as to protrude toward the rear surface, and in a state in which the front housing is attached to the rear housing, the rib extends to the circuit on the front side of the plurality of circuit boards. The height should be such that it contacts the surface of the substrate.

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), swinging the club will generate a BtoB connector. connections will not come loose. As a result of the structure in which the ribs of the front housing are brought into contact with the surface of the circuit board on the front side, even if centrifugal force acts on the circuit board in the direction of loosening the connection, the ribs exert the force on the circuit board. because it can accept

Moreover, the object mounting structure of the present invention can further include the following configuration.
(21) The object is an exercise device that is used by gripping and swinging a grip, the object is an electronic device containing a plurality of circuit boards connected by a board-to-board connector in a housing, and the housing is an electronic device. The front-side housing is composed of a back-side housing for fixing the 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. (1) is attached with a cushion member that abuts on the surface of the front side circuit board among the plurality of circuit boards in a state of being attached to the back side housing.

In the same way that configuration (20) suppresses outward movement of the front circuit board by means of ribs on the front housing, configuration (21) allows the cushion member to prevent the front circuit board from moving outward. It is possible to restrict the movement of the board and prevent loosening of the connection of the board-to-board connector (BtoB connector).

Moreover, the object mounting structure of the present invention can further include the following configuration.
(22) The object is an exercise device that is used by gripping and swinging a grip, the object is an electronic device containing a plurality of circuit boards connected by a board-to-board connector in a housing, and the housing is an electronic device. The plurality of circuit boards is composed of a back-side housing for fixing a back-side circuit board of the plurality of circuit boards, and a front-side housing attached so as to close the front of the back-side housing. The substrates are adhered to each other by a double-sided adhesive mat having double-sided adhesive layers.

Configuration (22) is different from suppressing and regulating the movement of the circuit board from the outside, but the double-sided adhesive mat is fixed to the back side housing to prevent the circuit board on the front side from moving outward. The movement of the circuit board on the front side is restricted by the action of attracting it toward the circuit board on the back side, and the action of preventing loosening of the connection of the board-to-board connector (BtoB connector) is exhibited.

In addition, the object attachment structure of the present invention having at least the configurations (1A) and (1B) can further include the following configurations.
(31) A tightening strength changing structure for changing the tightening strength of the fastener.

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

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

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

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

By using one of the hanging rings, you can use it in an easy-to-install method that reduces the stretching force, or use another hanging ring to increase the tightening force, and it can be used firmly for thin objects. You can use it by wearing it.

In addition, the object attachment structure of the present invention having at least the configurations (1A) and (1B) can further include the following configurations.
(41) As the stretching force reducing structure, a cushion body having a thickness capable of being compressed and deformed when tightened by the fastener is sandwiched between the object body and the object.

The compression deformation of the cushion body reduces the stretching force during tightening work, and after installation, the reaction force associated with the compression deformation of the cushion body exerts the tightening force together with the tensile reaction force of the fastener, making the stretching work easier. Despite the fact that it is easier, it can be in a firm wearing state.

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

Hereinafter, as embodiments of the object mounting structure of the present invention, several examples will be described in detail based on the drawings, taking a golf swing sensor mounting structure as an example. A golf swing sensor is attached near the grip of the golf club shaft and measures acceleration information, etc. when the golf club is swung. This is for finding and displaying the trajectory, etc., and helping the player correct his or her habits.

In the golf swing sensor mounting structure as Example 1, as shown in FIG. It is a mounting structure that sandwiches the

For this attachment, first, as shown in FIG. It is attached to hooks 12a to 12c for holding the band formed so as to protrude laterally from the band so as to be in a state of being prevented from coming off. Then, the other end 2b of the rubber band 2 (hereinafter referred to as the other end 2b) is pushed while pressing the rubber contact member 20 attached to the back side of the golf swing sensor 1 against the shaft 3a at a position near the grip 3b of the golf club 3. (referred to as "free end 2b") is hooked on hooks 13a to 13c for latching formed so as to protrude laterally from the right side surface of the rear housing 11 of the golf swing sensor 3. As shown in FIG. As a result, as shown in FIG. 1(C), the shaft 3a of the golf club 3 is sandwiched between the rubber contact member 20 and the rubber band 2 from the front and back, and the golf swing sensor 1 is attached to the shaft of the golf club 3. 3a. In this state, a tensile force is generated in the rubber band 2 in the spanning direction, and the force that tends to shrink against this tensile force acts as a force that tightens the shaft 3a of the golf club 3. As shown in FIG.

As shown in FIG. 2, the rubber band 2 has three openings 2c to 2e arranged in the vertical direction. Four cord-like portions 2f to 2i located above and below these three openings 2c to 2e are provided as portions that generate a pulling force.

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

The four string-like portions 2f to 2i arranged in the vertical direction all have a circular cross section with the same diameter, and fill the adjacent R-angled portions of the openings 2c to 2e at the base end 2a. are integrated. Therefore, the base end 2a of each of the openings 2c to 2e is closed with a longitudinal cord having the same diameter as the cord-like portions 2f to 2i.

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

In this embodiment, the openings 2c to 2e of the rubber band 2 configured in the shape of a compound ring serve as a loop portion.

As shown in FIGS. 3 to 8, the golf swing sensor 1 has an L-shape extending laterally and bent forward so that the openings 2c to 2e of the rubber band 2 can be hooked at the same time. A rear housing 11 provided with hooks 12a to 12c and 13a to 13c having a comb-like structure such that three comb teeth are arranged in the vertical direction in a cross section, and a rear housing 11 closing the front side of the rear housing 11. and a front housing 15 forming a housing space for housing substrates and the like.

The front housing 15 has an overall semicylindrical outer surface 15a and an upper tapered surface 15b that tapers upward. A switch window 15d through which a power switch can be seen is cut out from the upper end surface 15c from the rear, and a circular hole 15e through which an LED can be seen is formed in the front central lower portion of the upper tapered surface 15b. In addition, a terminal window 15g through which the terminals can be seen is cut out from the rear in the bottom surface 15f of the front housing 15. As shown in FIG.

As shown in FIG. 3C, the hooks 12a to 12c and the hooks 13a to 13c project from the left and right side surfaces of the rear housing 11 so that the vertical position and the amount of projection in the horizontal direction are symmetrical. It is Further, the hooks 12a to 12c and the hooks 13a to 13c have the same projecting amount in the front-rear direction as shown in FIG. 3(A) and the like. 4(A) and 4(B), the hooks 12a-12c have projections 14a-14c for preventing detachment on the inner surface of the tip of the wall-shaped portion extending forward. protruded. The distance between the tips of the projections 14a-14c and the left and right side surfaces of the rear housing 11 is smaller than the diameter of the base end 2a of the rubber band 2, so that the rubber band 2 can be attached to the hooks 12a-12c. 1(B), the rubber band 2 is integrated with the golf swing sensor 1, and when the golf club 3 is attached to the shaft 3a, the sensor is attached to the shaft 3a. It is designed so that it does not deviate from 1.

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

The rubber abutting member 20 has an outer shape that fits in the rectangular recessed portion 11a. It is constructed as a rubber molding. As shown in the enlarged views of FIGS. 4(A) and 4(B), the V-groove portion 22 has a contact surface 22b that tapers rearward as a whole so that the bottom surface 22a of the groove 22a becomes the rear side as it goes downward. It has. As shown in FIGS. 1(B) and 1(C), the shaft 3a of the golf club 3 has a tapered outer shape such that the grip 3b side is thicker and the head side is thinner. be.

As shown in FIG. 7, the rubber abutment member 20 is formed with engagement recesses 23a formed by notching the sides from the front to the middle of the rear in the left and right upper and lower portions of the flat surface 21 on the front side. ing. A circular recess 23b located on the center line in the height direction of the upper side of these engaging recesses 23a is also formed so as to be recessed rearward from the flat surface 23. As shown in FIG.

The rectangular recessed portion 11a of the rear housing 11 is provided with a circular projection 11b projecting rearward from the front and engaging projections 11c projecting inwardly from the left and right side surfaces. These engaging projections 11c are engaged with the engaging recesses 23a of the rubber abutment member 20 to attach the rubber abutment member 20 to the rectangular recessed portion 11a of the rear housing 11 so as not to come off. It is. Further, the circular projection 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 abutment member 20, which is separate from the housing 10, is fitted into the rectangular recessed portion 11a of the rear housing 11 so as to be positioned and prevented from coming out of the housing 10. It will be attached to the back side of the

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

Since the abutting member 20 itself is made of rubber, it can be removed by bending it with a finger if it needs to be replaced or the like. As a result, it is possible to easily replace the golf club with one having an abutment surface shape with improved adhesion to the shaft according to the type of golf club.

As shown in the exploded views of FIGS. 6 to 8, the golf swing sensor 1 includes a sensor board 31, a Bluetooth board 32, and a housing 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 with a rubber contact member 20 mounted on the back side.

In this assembly, the sensor board 31 and the Bluetooth board 32 are assembled in parallel with each other via the BtoB connector 34 . At this time, the sensor board 31 is in a state where the front surfaces of the edges of the upper and lower notch portions 31a and 31b at oblique positions abut against the rear ends of the screw bosses 15h projecting from the inner surface of the front housing 15. and fixed to the front housing 15 with screws.

On the inner surface of the front housing 15, a horizontal rib 15i protruding rearward is provided near the portion where the front surface of the Bluetooth board 32 is exposed. The height of the horizontal rib 15i in the front-rear direction is such that when the sensor board 31 is screwed and fixed to the front housing 15, the front surface of the Bluetooth board 32 attached to the front side thereof by the BtoB connector 34 just hits. It is As a result, the front surface of the Bluetooth board 32 is pressed by the horizontal ribs 15i of the front housing 15, so that the Bluetooth board 32 is assembled in the housing in a state in which it is difficult to shift in the front-rear direction.

Further, during this assembly, the tip of the light guide 35a of the LED component 35 provided on the upper front surface of the sensor substrate 31 faces the circular hole 15e of the upper tapered surface 15b of the front housing 15, and the sensor The tip of the operation portion 36a of the slide switch 36 provided on the upper back surface of the substrate 31 projects from the switch window 15d of the upper end surface 15c of the front housing 15. As shown in FIG. Furthermore, during this assembly, a terminal cover 40 is also assembled so as to cover the USB terminal 37 provided on the lower 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 into the depression 15k formed around the terminal window 15g on the bottom surface 15f of the front housing 15 and the depression 11k (see FIGS. 6 and 7) on the bottom surface of the rear housing 11. 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 and hooking the fingertip into the recess 11k extending to the rear bottom surface of the housing 10. As shown in FIG.

The battery 33 is assembled so as to be accommodated in the battery storage frame 11m on the front side of the rear housing 11. As shown in FIG. Therefore, the battery 33 is housed on the back side of the sensor substrate 31, and wiring connection to the sensor substrate 31 can be performed from the back side. If a connector is used for the connecting portion, replacement becomes possible, and by removing the rear housing 11, replacement with a new one can be easily executed.

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. The four string-like portions 2f to 2i of the rubber band 2 are provided, and the three openings 2c to 2e are used as hanging loops to span between the hooks 12a to 12c and the hooks 13a to 13c. The shaft 3a of the golf club 3 is sandwiched between the rubber abutting portion 20 and the cord-like portions 2f-2i by the tensile force generated in the rubber cord portions 2f-2i. It is possible to reduce the stretching force when hooking on the hooks 13a to 13c. Further, the retaining hooks 12a to 12c are provided with detachment-preventing projections 14a-14c, and as a result, the mounting work can be performed in the detachment-preventing state as shown in FIG. The work of pressing the sensor 1 against the shaft 3a and turning the rubber band 2 to the back of the shaft 3a is easy, and the sensor 1 is less likely to 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 being able to reduce the stretching force, it is possible to easily carry out the operation of hooking the hanging ring portions (the free end sides of the openings 2c to 2e) on the hooks 13a to 13c.

In addition, since the rubber band 2 has four cord-like portions 2f to 2i, even if one of them is broken, the other portions are still connected. It is also possible to have the role of a safety device that can be removed. By providing the role of this safety device, the string-like parts 2f-2i can be thinned and the rubber band 2 can be thinned, and as a result, the amount of protrusion of the hooks 12a-12c and 13a-13c can be reduced. , and the effect of reducing the external dimensions of the sensor main body is exhibited.

Furthermore, in this embodiment, as a result of sandwiching the shaft 3a between the rubber abutting portion 20 on the back side of the sensor body and the rubber band 2, the frictional force between the rubber and the shaft material realizes a firm mounting state. In addition, since the rubber contact portion 20 is provided with the contact surfaces 22b, 22b corresponding to the taper of the shaft 3a of the golf club 3, which tapers toward the tip, the rubber contact member 20 is adapted to the shaft 3a. The pressing force becomes constant, and problems such as the sensor being installed at an angle can be prevented.

Further, since the switch 36 for power supply is located on the upper end surface 15c of the sensor body, it is easy to operate the switch while gripping the grip 3b of the golf club 3, and the switch can be switched by accidentally touching the thigh or the like. It is also difficult to cause the problem of falling off. In addition, as a result of the LED being visible through the upper tapered surface 15b, the state of the power supply can be easily confirmed even while gripping the grip 3b of the golf club 3. FIG.

Further, the terminal cover 40 is attached so that the hinge portion 41 is positioned on the front side and the knob portion 42 is positioned on the back side, and is configured to be flush with the bottom surface of the housing. The problem of accidentally opening the door by touching it is also less likely to occur.

In addition, the free end of the rubber band 2 is provided with a flat portion 2j and a bulging portion 2k so that it can be easily picked up with fingers and the pinched fingers are less likely to come off, thereby improving the operability in the pulling operation. .

Furthermore, the rubber abutment member 20, which ensures resistance to slippage due to friction when attached, is not simply a rubber plate but abuts with a line touch at a position outside the axis of the shaft 3a. As a result of the fact that the thickness of the contact portion is sufficient and the compressive deformation ability is enhanced, the adhesion is enhanced.

In this embodiment, the battery 33 is mounted on the rear side of the sensor board 31 so as to be accommodated in the battery storage frame 11m of the rear housing 11. Therefore, the rear housing 11 can be removed to replace the battery. 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 via 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 is not loosened and the various functions of the sensor are not affected.

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 object to be mounted is the shaft portion of the golf club as in the first embodiment. The golf swing sensor 101 has substantially the same configuration as that of the first embodiment, and a sensor board, a Bluetooth board, etc. are housed inside a housing 110 constructed by assembling a front housing 115 and a rear housing 111. , the switch is exposed from the upper end surface 115c, and the light guide of the LED is exposed on the upper tapered surface 115b. A thick rubber contact member 120 having a V groove is detachably attached to the rear surface of the rear housing 111 .

The first difference from Example 1 is that a rubber ring 102 using a general-purpose O-ring is used as a fastener, as shown in FIG. 9(C).

As another difference, in the second embodiment, since a simple ring-shaped rubber ring 102 is used, the rear housing 111 can be used as a hook serving as a holding portion, as shown in FIGS. A hook 112 projecting leftward from the left side of the hook and bending forward and having a large width in the vertical direction is adopted. It is constructed so that one end of the rubber ring 102 can be retained in a locked state.

Further, as one of the features of the second embodiment, instead of the hooks 13a to 13c of the first embodiment, a latching portion 113 having a rotating lever 113a is provided on the right side surface of the rear housing 111. FIG. The rotating lever 113a is made of spring steel and is U-shaped and is rotatably mounted from the inside of the upper and lower boss portions 113b. ) and a raised position raised to the front side (see FIGS. 9B and 9E). A structure is adopted in which it is fitted into a groove 113c formed so as to cut in the direction to prevent it from coming off unintentionally.

In addition, the pivot lever 113a has an inner curved portion 113e at its root side so that the U-shaped main body 113d approaches the housing 110 side in the raised position. As a result, the rubber ring 102 can be hooked to the outside of the boss portion 113b so as to be slid into the front surface of the boss portion formed between the inner curved portion 113e and the housing 110. .

For mounting, after the rubber ring 102 is locked onto the hook 112, the sensor is set so that the rubber abutment member is pressed against the shaft 3a, and the rotating lever 113a is tilted to the collapsed position. While pulling the free end of the manufacturing ring 102, it is hooked from the tip of the rotating lever 113a so as to be temporarily hooked (see FIG. 9(D)). Next, the rotating lever 113a is rotated to the raised position (see FIG. 9(E)). As a result, according to the principle of leverage, the rubber ring 102 can be stretched with a small amount of force, and the rubber ring 102 is hooked on the outside of the boss portion 113b, and the sensor 101 is attached to the shaft 3a of the golf club. can be attached with

In this embodiment, by utilizing the assisting force of the rotating lever 113a, the mounting work of the rubber ring 102 is facilitated, and it is also possible to use a part such as a general-purpose O-ring. This is the result of the principle of leverage that allows the rubber ring 102 to be stretched firmly without applying a large force. Since the device can be firmly stretched and held down with a small amount of force, the force required for stretching by the person who performs the installation 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 a sensor board and a Bluetooth board are housed inside a housing 210 constructed by assembling a front housing 215 and a rear housing 211. The switch is exposed from the upper end surface 215c, the light guide of the LED is exposed on the upper tapered surface 215b, and a thick rubber contact member 220 having a V groove is detachably attached to the rear surface of the rear housing 211. There is.

Further, in Example 3, as in Example 2, a rubber ring 202 using a general-purpose O-ring as shown in FIG. 10B is used as a fastener. Since the simple ring-shaped rubber ring 202 is used, the hook serving as the holding portion protrudes leftward from the left side surface of the rear housing 211 and bends forward as in the second embodiment. A hook 212 with a large width is employed, and a plate-like projection 214 protruding inward is provided approximately in the middle of the hook 212 in the vertical direction so that one end of the rubber ring 202 can be held in a non-disengaged state. bottom.

On the other hand, unlike the second embodiment, as shown in FIG. 10(A), the hook for latching is provided with an upward hook portion 213m that protrudes rightward from the right side surface of the rear housing 211. An upper hook 213a and a lower hook 213c projecting rightward from the right side surface of the rear housing 211 and having a downward hooking claw portion 213n are provided. Between the upper hook 213a and the lower hook 213c, there is formed a gap 213b through which a finger can pass.

For mounting, after the rubber ring 202 is kept in the hook 212, the sensor is set so that the rubber abutting member is pressed against the shaft 3a, and as shown in FIG. The free end side of the ring 202 is hooked on the upper hook 213a from above. This state is a temporary hooking state, and can be implemented by slightly stretching the rubber ring 202 . After that, put your finger on the portion hanging down in the gap 213b, pull it downward, avoid the lower end of the downward hooking claw portion 213n, and hook it to the lower hook 213c to complete the hooking state. The operation of pulling down the rubber ring 202 after temporarily hooking it on the upward hooking claw portion 113m is simplified as a result of forming a starting point for stretching by the temporary hooking. As a result, the operation of attaching the sensor 201 to the shaft 3a of the golf club can be easily carried out.

Incidentally, it is also possible to use the hook 213c on the lower side instead of the upper side for temporary hooking and pull it upwards for the actual hooking. In any case, instead of bending the tip of the hook on the latching side forward to create a wall in the diameter direction of the club shaft, a protrusion in the vertical direction (in the axial direction of the club shaft) is added, In the third embodiment, the amount of pulling of the rubber ring 202 is reduced to reduce the force during attachment.

Next, Example 4 will be described with reference to FIG. Example 4 also relates to the mounting structure of the golf swing sensor, and the object of attachment is the shaft portion of the golf club as in Examples 1-3. Further, the golf swing sensor 301 has the same structure as the hook in the third embodiment. 11, the flat surface 321 on the front side of the rubber contact member 320 is provided with frame-shaped ribs 326 protruding toward the front, 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 311 a , and the rubber contact member 320 and the rear housing 311 are arranged so that the frame-shaped rib of the contact member 320 receives pressure when the sensor is attached. 326 and the frame-shaped portion 316 of the rectangular recessed portion 311a of the rear housing 311 are different from the third embodiment. The configuration such as the shape of the back side of the rubber contact member 320 is the same as that of the third embodiment.

As a result of adopting such a configuration, an internal structure is provided in which a gap remains on the front side of the flat surface 325 when the rubber contact member 320 is compressed and deformed. Since this gap has a depth that is the sum of the height of the frame-shaped rib 326 and the height of the frame-shaped portion 316, a plate-shaped battery 333 that is thick enough to fit in this gap is used instead of the battery 33 employed in the first embodiment. A feature of the fourth embodiment is that it is housed.

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

The thickness of the battery main body 333d of the plate-shaped battery 333 is set to be larger than the height of the frame-shaped portion 316 formed on the rear housing 311 side, so that when the rubber contact member 320 is removed, a finger can be hooked on the battery body 333d. It has an easy configuration. The width of the plate-shaped battery 333 is narrower than the width of the gap in the horizontal direction, and the length thereof is shorter than the length of the gap in the vertical direction. In this case, the board portion 333a is positioned upward, and the lead wire 333b is long enough to fit beside the plate-shaped battery 333. As shown in FIG.

As a result, when the golf swing sensor 301 of Example 4 is attached to the shaft of the golf club and the golf club is swung, a centrifugal force is generated in the axial direction of the shaft from the grip to the head, and the golf swing sensor 301 is accommodated in the gap in a loose state. The plate-like battery 333 moves toward the bottom of the housing, but since the plate-like battery 333 is stored so that the substrate portion 333a that is easily damaged faces the upper side, the substrate portion 333a is placed on the inner surface of the rectangular recessed portion 311a. is not strongly pressed against In addition, the pressure in the attached 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 pressure during attachment. Furthermore, since the lead wire 333b is also accommodated beside the plate-like battery 333, it will not be damaged by pressure during installation.

Next, Example 5 will be described with reference to FIG. Example 5 is the same as Example 4 except for the following points. The difference is that the knob portion 442 of the terminal cover 440 has a length that allows it to wrap around the arc-shaped recess 411 d of the rear housing 411 . As a result, the golf swing sensor 401 can be attached so that the knob 442 of the terminal cover 440 is sandwiched between the shaft of the golf club and the possibility that the terminal cover 440 will accidentally open due to contact with the thigh or the like can be further reduced. It is characterized by being able to

Example 6 is similar to Example 1, and as shown in FIG. 13, a golf swing sensor 501 further includes a cushion member 539 on the front side of a Bluetooth board 532 . As a result, the Bluetooth board 532 will be in a more stable mounting state. In this case, the mounting state of the Bluetooth board 532 is stable even without the horizontal rib 15i employed in the first embodiment.

Example 7 is the same as Example 1, and as shown in FIG. This also allows the Bluetooth board 632 to be attached in a more stable state. Even in this case, the mounting state of the Bluetooth board 532 is stable even without the horizontal rib 15i employed in the first embodiment.

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

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

The motion sensor 730 incorporates sensors for motion detection on 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 . The LED lamp 732 indicates the state of the motion sensor 730 by the way it lights, as will be described later. A micro USB terminal 733 is for attaching an accessory AC adapter when charging the lithium-ion battery incorporated in the motion sensor 730, and is always covered with a cover.

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

The motion sensor 730 has the same internal structure, external shape, etc. as the golf swing sensor 1 described in the first embodiment. 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 processing for displaying the swing trajectory. This system can display the swing trajectory by switching between the view from behind and the view from above, and can also record the direction of the head at the moment of impact. It is configured so that it can be

As shown in FIG. 16, the mounting belt 750 has three horizontally long openings 752c to 752e arranged vertically from a base end 752a toward a free end 752b. Four string-like portions 752f to 752i positioned above and below these three laterally elongated openings 752c to 752e are provided as portions that generate a pulling force when attached to the shaft of a golf club.

These three laterally elongated openings 752c to 752e include a first middle partition 752m reaching from the inner surface of the cord-like portion 752f to the inner surface of the cord-like portion 752i at a position about 1/3 of the opening length from the base end 752a, A second middle partition 752n extending from the inner surface of the cord-like portion 752f to the inner surface of the cord-like portion 752i at a position about 1/4 of the opening length on the right side thereof creates three small openings 752c1 to 752c3 in the longitudinal direction. It is divided into 752d1 to 752d3 and 752e1 to 752e3.

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

The four string-like portions 752f to 752i arranged in the vertical direction have an oval cross section with a long side approximately twice the diameter of the base end 752a having a circular cross section. It is made flush with the base end 752a and is thicker than that of the first embodiment so as to protrude toward the front side. The amount of protrusion is set so as not to protrude outside of the bulging portion 752k, so that it does not cause a sense of discomfort in appearance. In addition, these cord-like portions 752f to 752i are integrated so as to be continuous with the portion forming the base end 725a at the base end 752a and fill the adjacent R-angled portions of the laterally long openings 252c to 2522e. there is

The laterally long openings 752c to 752e are integrated by a flat plate portion 752j so as to fill adjacent R-angled portions on the free end 752b side as well. The flat plate portion 752j has the same thickness as the diameter of the base end 752a. It is integrated with the flat plate portion 752j. A free end 752b, which is the tip of the flat plate portion 752j, is integrally formed with a bulging portion 752k so as to bulge in the front-rear direction. The flat plate portion 752j has an area that can be picked up with fingers, and the bulging portion 752k has front and rear surfaces continuous from the end of the flat plate portion 752j on the free end side, gradually increasing toward the free end. The thickness of the flat plate portion 752j is increased to about three times the maximum thickness, and serves to make it difficult for fingers pinching the front and rear surfaces of the flat plate portion 752j to come off in the direction of the free end.

In this embodiment, small openings 752c1 to 752e3 at the left end of each of the laterally elongated openings 752c to 752e of the mounting belt 750 configured in the shape of a compound ring correspond to the loop portions. In this embodiment, as will be described later, the small openings 752c2 to 752e2 in the center can be used as loops with the first intermediate partition 752m regarded as the base end. The small openings 752c3 to 752e3 at the right end can also be used as a hanging ring in some cases, but in this embodiment, the second middle partition 752n is mainly intended to reinforce the string-like portions 752f to 752i. It is provided for stabilizing the lengthwise extension of the string-like portions 752f-752i when the small central openings 752d1-752d3 are used as the hanging ring portions.

The motion sensor 730 has substantially the same configuration as the golf swing sensor 1 of Example 1, as shown in FIG. Similar components such as an L-shaped hook are denoted by the same reference numerals as those described in the golf swing sensor 1 of Example 1, and detailed description thereof will be omitted. The motion sensor 730 has a rubber contact member 735 attached to the back side of the rear housing 11. The back side of the rubber contact member 735 is formed into an arc-shaped groove 736. The motion sensor 730 is rectangular with a thickness of 5 mm so as to cover the entire back side. The difference is that it has a structure in which a sponge body 737 with dimensions of 40.5 mm×15 mm is attached. As shown in the cross-sectional view, the rubber contact member 735 has a rim 738 with a height of 1 mm and a thickness of 1 mm. The entire surface is pasted along the arc of 736 . The sponge body 737 is attached so as to fit inside the edge 738, and as a result, even if the adhesive is peeled off during use, the edge is less likely to rise. 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 the base end 752a of the mounting belt 750 projects laterally from the left side surface of the rear housing 11 of the motion sensor 730. 18(C), the sponge body 742 on the back surface of the motion sensor 730 is attached to the grip 3b of the golf club. The free end 752b of the mounting belt 750 is pulled straight and wrapped around the back of the golf club 3 so as to be pressed against the shaft 3a at a near position, and protrude 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 latching.

In this embodiment, since the sponge body 737 is used as the club installation surface of the motion sensor 730, the tensile force generated in the mounting belt 750 and the compressive force generated in the sponge body 737 act to move the motion sensor 730 against the golf club 3a. It can be worn firmly.

An appropriate mounting position is a position where the motion sensor 730 is located on the opposite side of the face surface and about 2 cm below the grip 3b, as shown in FIGS. 18(C) and (D). Although calibration can be performed by calibrating the mounting position of the sensor, which will be described later, when measuring the swing path of the club, it is better not to place the sensor too far below the grip 3b. is in the range of At this time, the power switch 731 and the LED lamp 732 are attached so as to be positioned on the grip side.

In addition, as shown by the lower arrow in FIG. It can also be worn to tighten it more tightly.

When using the trainer system of this embodiment, first, as shown in FIGS. Charge the battery from a household power source. At this time, the LED lamp 713 of the trainer device 710 and the LED lamp 732 of the motion sensor 730 are lit in red during charging and in blue when charging is completed. After charging is completed, the micro USB terminal 781 is pulled out and the covers 719 and 734 are firmly closed. In addition, the trainer device 710 and the motion sensor 730 are configured to automatically stop charging when fully charged, so as to prevent overcharging.

Also, as shown in FIG. 20A, the trainer device 710 has the cover 719 opened, the micro SD card 790 is loaded, 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. The angle adjustment bracket 770 is composed of a base 771 and a bracket 773 having a ball-shaped fitting portion 772, as shown in FIG. The projection 774 of the bracket 773 is inserted into the hole 710a provided in the . By attaching the angle adjusting bracket 770, the trainer device 710 can be rotated vertically and horizontally to adjust the angle so that the main body is horizontal as shown in FIG. 20(D). As a result, accurate measurement and the like can be performed even in an uneven place.

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

"Head speed" in "Swing mode" is the speed of the club head, "estimated flight distance" is the flight distance calculated from the club used and the head speed or ball speed, and "ball speed" is the speed of the ball. "Meat rate" is the numerical value of "ball speed divided by head speed" and expresses the efficiency of the swing transmitted from the club to the ball. In addition, the display can be switched among horizontal one-item display, history display, and graph display.

"Arc mode" is a mode performed by wearing the motion sensor 730, and has a configuration in which the display of "face trajectory" and "shot data" can be switched in addition to the "swing trajectory". The configuration is such that a "model" for the "swing trajectory" can also be displayed.

The golf swing trainer system 700 of this embodiment, as shown in FIG. It has a system configuration that can display various types of "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 section 726 , a recording section 727 , a group of switches 728 and a transmission/reception section 729 .

Doppler sensor 721 is a microwave Doppler sensor with an output frequency of 24.15 GHz. The output signal of the Doppler sensor 721 (one wave corresponds to 6 mm movement of the golf club head) is amplified by the amplifier 722 and compared with the reference value by the comparator 723. 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 .

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

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

The first microcontroller 724 calculates an estimated flight distance and a hit rate based on the head speed calculated by itself and the ball speed calculated by the second microcontroller 725 . Then, the first microcontroller 725 performs display on the display control section 726 and recording on the recording section 727 based on the head speed, ball speed, estimated flight distance, and hit rate data. Note that the first microcontroller 724 performs display switching, mode switching, and the like based on inputs from the switch group 728 . When the Arc mode is selected by operating the switch, the swing trajectory is calculated and displayed based on the detection signal from the motion sensor 730 received by the transmitting/receiving section 729 .

In addition, the first microcontroller 724 is also configured to adjust the gain of 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 .

Motion sensor 730 includes microcontroller 741 , sensor 742 , LED controller 743 , and transceiver 745 .

The microcontroller 741 receives the detection signal from the sensor 742 , executes necessary arithmetic processing, and transmits the result via the transmission/reception section 745 . The signal transmitted from the transmitting/receiving section 745 is received by the transmitting/receiving section 729 of the trainer device 710, and various displays and the like in the above-described Arc mode are executed. The sensor 742 is a motion detection sensor for three axes of acceleration and three axes of angular velocity. The microcontroller 741 also performs processing for responding to data transmission requests received from the trainer device 710 via the transceiver 745 . The microcontroller 741 also controls the lighting/blinking state of the LED lamp 732 via the LED control unit 743 .

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

(1) Lights up in "red" in the "charging" state.
(2) In the "charging (power on)" state, "red" and "yellow" are lit alternately. The blinking pattern of "red" and "yellow" in this case changes depending on the Bluetooth connection status.
(3) When the state of "charging completed" is reached, "blue" lighting is performed.
(4) In the state of "charging completed (power on)", "blue" and "light blue" are lit alternately. In this case, the "blue" and "light blue" flashing pattern changes depending on the Bluetooth connection status.
(5) In the state of "abnormal charging", light up in "pink". This is to inform the user of the possibility of temperature abnormality or overcharging.
(6) In the state of "power on (Bluetooth/unconnected)", "green" flashes quickly.
(7) In the state of "power on (during Bluetooth pairing)", slow flashing of "green" lighting and extinguishing is performed.
(8) In the "power on (Bluetooth/connected)" state, the LED blinks in a pattern of turning on "green" twice and turning off for a predetermined period of time.
(9) Lights up in "green" in the state of "detecting motion". This pattern is executed when the trainer device 710 is activated in "Swing Mode", "Arc Mode" or "Practice Mode" with a Bluetooth connection.
(10) In the state of "motion calculation in progress", blinking is performed in a pattern of turning on "green" twice and turning off for a predetermined time. "Motion calculation in progress" is a state in which the swing trajectory and the like are being calculated after the swing is performed. This is a display for making the next swing wait until the state of (9) "green lighting" is reached.

The lighting pattern of (9) “Continue green lighting” in the motion sensor 730 is obtained by the first microcontroller 724 of the trainer device main body 710 receiving the detection signal from the motion sensor 730 (transmitted at a sampling interval of 2 ms). It is started by notifying the motion sensor 730 by wireless communication that it has been determined that "the user is in a substantially stationary state with the golf club held" based on the above. In addition, the above-mentioned (10) blinking pattern of “lights green twice and turns off” in the motion sensor 730 is determined by the first microcontroller 724 of the trainer apparatus main body 710 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 the club is in a "almost stationary state" depends on whether or not the club is in a stationary state. There is some latitude in the judgment conditions. Also, "end of swing" is determined using a detection signal corresponding to "impact of impact". Therefore, in the case of a "missed swing", the judgment is not "end of swing" but "release of stationary state". It becomes possible to

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

As shown in FIG. 24A, the trainer device 710 is powered on by pressing and holding the power button 716 for two seconds or more in the power off state, and by pressing and holding the power button 716 for two seconds or more in the power on state. is configured to turn off the power by The motion sensor 730 is powered on by turning on the power switch 731 as shown in FIG. 24(B). As described above, immediately after the power is switched on, the LED lamp 732 is in a "green blinking" state. Note that FIG. 24B shows a state in which the power switch 731 is turned off.

When the menu button 712 is pressed after the power of the trainer device 710 is turned on, a menu screen is displayed on the display screen 711 as shown in FIG. 24(C). As shown, in this embodiment, "swing mode", "arc mode", "setting mode", "practice mode", "arc playback mode", and "power off" can be selected from the menu screen. Mode selection can be performed by touching a mode button on these menu screens with a finger.

(1) "Swing mode" is a mode for detecting and displaying "head speed", "estimated flight distance", "ball speed" and "meat rate", as described above. Also, when certain criteria are met, a "nice shot animation" will be displayed. Furthermore, the average value of swing data for each club and numerical values for each club can also be displayed. Also, each item can be displayed as a graph.
(2) “Arc mode” is a mode in which the motion sensor 730 detects and displays the trajectory of the club.
(3) "Setting mode" is a mode for changing the settings of the main body such as date and time and left-handed settings.
(4) "Practice mode" is a mode for automatically or manually setting the target distance. In this mode, when certain criteria are met, a "Nice On Animation" is displayed.
(5) "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 long-pressing the power button 716 .

To use this system, first set the date and time. By setting the date and time, the date and time of recording can be added to the data detected in the golf swing. When checking with data management software, you can use the recording date and time as a mark to select files and compare data. Note that the default setting is 00:00 on January 1, 2013 immediately after the battery is installed.

As shown in FIG. 25A, the operation method is to touch "setting" 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. Enter the year, month, day, hour and minute in this order by operating the "ten key", "clear" and "OK".

[Swing mode]
Next, the operating procedure of the "swing mode" will be described. As shown in FIG. 25B, when "swing" on the menu screen is touched and the club button on the switched screen is touched, a club selection screen is displayed. In this embodiment, "wood,""utility,""iron,""wedge," and "putter" are prepared as selectable club types. To select the No. 1 wood, as shown in the figure, touch "Wood" and touch "1W" on the changed 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 when the ball is swinging or hit with a club with a large loft angle (irons, wedges), it is calculated based on the head speed. The flight distance calculated from the ball speed takes into consideration the coefficient of restitution of the head and the ball, so it is possible to calculate a more accurate numerical value than the flight distance calculated from the head speed.

Here, in the system of this embodiment, calculation processing is performed with the "flying distance calculation reference" determined as follows.
(1) Calculated based on coefficients obtained from numerous data collections based on general clubs on the market.
(2) The flight distance is calculated as a value including the run, assuming an average spin rate, no wind, and flat terrain.
(3) The directionality of the hit ball is not considered.
Depending on the club used, there may be an error between the indicated distance and the actual distance.

In order to calculate such a flight distance, in this embodiment, the type of club and the loft angle are set in advance in the storage device of the trainer device 710 as shown in FIG. 25(C).
As for the wedge, a configuration is adopted in which the initial set value can also be changed.

"Meat 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 hit ratio (ball speed/head speed) is 1.40 or higher. "Nice shot animation" is displayed only when a wood club is selected.

Next, procedures 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 type club is selected. As shown in FIG. 26(A), the detection sensor 715 of the trainer device 710 is positioned about 1 to 1.5 m behind in the direction in which the ball is to be launched. Install horizontally. At this time, if the installation location is undulating, an angle adjustment bracket 770 is used (see FIG. 20(D)). The figure shows the case of hitting to the right.

As already described, the system of this embodiment is capable of simultaneously displaying four items as well as displaying one item horizontally. Basically, four items are displayed at the same time. As shown in FIG. 26B, when an item to be displayed is touched, the screen can be switched to a screen in which the item is horizontally displayed in a large size. As a result, the user can see the item that he/she wants to know the most from the position shown in FIG. 26(A).

When the user swings, the trainer device 710 executes arithmetic processing for head speed measurement, ball speed measurement, carry distance calculation, and contact rate calculation based on the signal from the Doppler sensor 721 . A message "Please wait" is displayed on the display screen 711 while this arithmetic processing is being performed. When the detection result is obtained, the detection result blinks and then switches to lighting to inform 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 saved as a history. The history can be deleted by touching the detection result screen for 2 seconds after the display of the detection result changes from flashing to lighting.

It should be noted that the head speed can be displayed even when swinging. As mentioned above, it has a function to calculate the distance based on the head speed even when the ball speed is not detected. When the flight distance is about 30 yards or less, no display is made.

The detection result obtained in this manner can be recorded by associating the date and time of acquisition with the detected data by "setting the date and time" as described above.

In addition, it may not be displayed correctly in the following cases.
(1) If the trajectory of the ball is high (the launch angle is large) or if it deviates to the left or right, it may not be possible to detect the ball speed.
(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 meat rate becomes low.
(3) When using a golf practice net, the ball speed may not be detected if the distance from the ball placement position to the net is less than 3m.
(4) If the ball speed is less than 20.0 m/s, it cannot be detected.
(5) It cannot be detected when the head speed is less than 15.0 m/s.
(6) Correct detection may not be possible if multiple units are used at a short distance. 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-type club is selected. In the initial settings, when the meet rate is 1.40 or higher, the "Nice Shot Animation" is set to be displayed. In addition, "Nice Shot Animation" also adopts a configuration that allows the setting to be changed to "Do not display".

Next, the installation position and the like of the device when the "putter" is selected in the "swing mode" will be described. In this case, first, as shown in FIG. 27A, "Swing" is touched on the menu screen, the club button is touched, and the putter is selected. Next, as shown in FIG. 27(B), the trainer device 710 is moved about 20 cm away from the ball launch line on the opposite side of the user, and about 20 cm ahead of the ball position in the launch direction. , and the detection sensor 715 is installed so as to face about 1 m ahead in the direction in which the ball is launched. At this time as well, the trainer device 710 is installed horizontally so that there is no obstacle between it and the ball. This figure also shows the case of hitting to the right.

When the user putts, the trainer device 710 executes calculation processing for ball speed measurement and estimated flight distance calculation based on the signal from the Doppler sensor 721, and the detection result is as shown in FIG. 27(C). Display estimated flight distance and ball speed. The display of the message "please wait" while the arithmetic processing is being performed and the switching from blinking to lighting when the detection result is obtained are the same as in the case of the wood.

The following conditions are adopted in the measurement and calculation for this putting.
(1) Green speed (stimp) is calculated assuming 7.8 feet.
(2) If the distance the ball moves is short (approximately 1 m or less), it cannot be detected.
(3) Head speed cannot be detected.
(4) Accurate detection may not be possible if there are moving objects or people in the vicinity of the detection area. Conversely, if there are moving objects or people near the detection area, they may be detected and displayed based on their movements.
(5) The distance may not match the actual distance due to turf, undulation, and other conditions.
(6) Correct detection may not be possible if multiple units are used at a short distance. Therefore, when using a plurality of units, it is desirable to keep a distance of at least 2 m from each other.

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

The "history display screen" is configured to display seven items each from the latest history, and by touching "next page", the display switches to the next seven items. The example shown in the figure relates to a No. 1 wood, where "No." in the upper row is a sequential number with the latest history being 1, "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 a structure is adopted in which each batch is displayed in one line.

In addition, the average values of head speed, ball speed, estimated flight distance, and hit rate are displayed on the top row. This average value does not change even if you touch the "next page" or "previous page", and by comparing it with the average value, you can know the success or failure of each swing.

By touching the club button and selecting another type of club, the history of the selected club can be checked. If no club is selected or all clubs are selected, the history is displayed with no numerical value entered in the average value column as shown in FIG. 28(B). Also, when only head speed is detected, such as practice swing, the ball speed and contact rate are blank.

As shown in FIG. 28C, when "graph display" is touched on the history function selection screen, the screen is switched to a 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. It should be noted that when "All" is touched on the history date confirmation screen, the date specification screen is not displayed. In this embodiment, the date is managed, and the hour and minute are not specified.

When the date to be displayed in the graph is selected in this manner, a "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 "meat 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 pieces of 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. . Further, by touching the club switching button, the club can be selected from this graph display screen. Furthermore, by touching the vertical axis setting button, the display range of the vertical axis can be changed.

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

When erasing the history, as shown in FIG. 29(C), touch the "History button" and touch "Erase" on the history function selection screen. together with "yes" and "no" buttons for confirmation. Then, when "yes" is touched, history deletion processing starts in the trainer device 710. FIG. When the history deletion is completed, a message "History has been deleted" is displayed, and after 2 seconds, the history screen returns. When "No" is selected for confirmation, the screen also returns to the history screen. When history deletion is completed, the number of histories becomes 0.

[Practice mode]
Next, procedures for executing the "practice mode" using the system of this embodiment will be described. "Practice mode" is for practicing shots aiming at a set target 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 (C). do.

When "AUTO" is touched, the target distance is randomly set between 50 and 150 yards by internal processing of the trainer device 710. FIG. When "MANUAL" is touched, operate the ten keys to input the target distance between 50 and 150 yards, and touch "OK" to set. As shown in FIG. 30(D), settable ranges and initial set values are defined for the upper and lower limits of the target set 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 radius of the green, and the unit of speed and distance can be changed by setting.

After setting the target distance, as shown in FIG. 30(E), the club button is touched to execute club selection. As shown, the putter is 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, and calculation processing is performed to determine whether or not to display the "nice on animation" in comparison with the set target distance.

The installation position of the device in the "practice mode" is the same as in the "swing mode", as shown in FIG. Place the trainer device 710 horizontally at a distance of 1 to 1.5 m with no obstacles between the trainer device 710 and the ball.

When the user swings, the trainer device 710 executes arithmetic processing for head speed measurement, ball speed measurement, flight distance calculation, and contact rate calculation based on the signal from the Doppler sensor 721, and detects the estimated flight distance. This detection result is flashed on the display screen. Then, if the estimated flight distance is within ±10 yards of the radius of the target distance, a "nice on animation" as shown in FIG. 30(G) is displayed on the display screen. When the blinking of the detection result ends, the next ball can be processed in the practice mode. As described above, the green radius for judging a good turn and whether or not to display a nice turn animation can be changed by setting.

[Arc mode]
Next, procedures for executing the "Arc mode" using the system of this embodiment will be described. “Arc mode” is a mode in which the trainer device 710 and the motion sensor 730 are used to record the swing trajectory of the swing. The motion is temporarily stored for each swing, but it is configured to disappear if the next swing is performed without saving. In order to save, the "save" button is touched for each stroke, and a maximum of 30 items can be saved in the storage device of the trainer device 710. FIG.

First, as shown in FIG. 31(A), the attachment belt 750 is used to firmly attach the motion sensor 730 so that the upper end of the motion sensor 730 is positioned approximately 2 cm below the lower end of the grip 3b of the club to be used. At this time, the motion sensor 730 is positioned 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, the club is selected, and the sensor attachment position and face surface are calibrated. This operation is performed by touching "setting" on the menu screen as shown in FIG. Touch "Club" to display the club setting screen and select a club, then touch "Sensor Mounting Position" and input the sensor mounting position 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, as shown in FIG. 31(D), return to the club setting screen and touch "face surface calibration". Then, the trainer device 710 displays a screen showing the method of face calibration in diagrams and text on the display screen. The user performs an operation of touching "OK" with the face of the club equipped with the motion sensor 730 aligned with the horizontal plane, according to the instruction by the diagram and text on the screen. When "OK" is touched, trainer device 710 communicates with motion sensor 730 to calibrate the face. At this time, a process of detecting the positional relationship between the motion detection position by the motion sensor 730 and the face surface is executed with reference 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 motion sensor 730 is also turned on.

Next, as shown in FIG. 31(E), as in the "swing mode", the trainer device 710 is placed horizontally on a flat, flat place with no obstacles between the player and the ball. Install at a position about 1 to 1.5m behind. In addition, by installing in this way, it will be in the state which can perform the measurement and calculation of "Arc mode" and "swing mode" simultaneously. Note that if the motion sensor 730 and the trainer device 710 are connected via Bluetooth, measurement and calculation in the “Arc mode” are possible. Therefore, for users who do not need data such as head speed, the installation method is not limited to that shown in FIG. It suffices to install the trainer device 710 at the

When the motion sensor 730 has been attached and the trainer device 710 has been installed as described above, confirm that the respective power sources are turned on, and touch "Arc" on 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 one of the following states: fast flashing of "green", repetition of lighting once and turning off, repetition of lighting and turning off twice, or continuous lighting.

As shown in the table of FIG. 21(A), fast blinking of "green" means "Bluetooth is not connected", repeating turning on and off once means "Bluetooth pairing", and repeating turning on and turning off twice. is "connected to Bluetooth" or "calculating motion", and the continuous lighting state is "detecting motion". It is in the "green" continuous lighting state that a swing can be performed to perform motion detection. The user can perform a swing at any time after confirming the continuous lighting state of "green". It should be noted that the continuous lighting state of "green" is a state in which the club is stationary according to the signal from the motion sensor 730, and a state in which no motion calculation processing is performed on the trainer device 710 side. Whether or not the club is stationary is determined on the side of the trainer device 710, and the determination conditions are set so that the stationary state can be determined even if the club is moved within a certain range. This takes into consideration that some users have a habit of slightly moving the club when taking an address posture.

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

When the user swings and impacts the ball, the hitting point is determined, and the trainer device 410 calculates the swing trajectory based on the sensor signals from the motion sensor 730 before and after that point. Then, as shown in the screen on the right side of FIG. 32(B), a moving image is displayed in which an image of a person moves as if swinging a club and a swing trajectory is drawn. The display of this video is played repeatedly, but it is not automatically saved. To save the swing trajectory, touch the "Save" button on the screen. Trainer device 710 saves the data on the swing trajectory currently displayed as a moving image when the save button is touched. The maximum storable number in this embodiment is 30.

When the screen repeatedly displaying the swing path is touched, as shown in FIG. Switch to a different display. Each display is repeatedly played back with a moving image.

Here, it is difficult to understand because colors 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 shown in the same color. A display mode is adopted in which the distinction can be judged by the color shade. In addition, in the case of a golf swing, since there is a turning point from an upswing to a downswing, the turning point is calculated, and the upswing part is blue, and the downswing part is red. may be changed. With these display modes, it is possible to distinguish between an upswing and a downswing even on the screen in which the swing trajectory has been drawn, and information for correcting the trajectory can be conveyed more accurately. In the present embodiment, processing for drawing the swing trajectory is performed using moving images, so that the trajectory of the upswing and the trajectory of the downswing can also be distinguished.

Also, when 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, and the ball is placed in the center so that it can be clearly read from the "rear" and "top" of FIG. A display mode is adopted in which the display position is shifted to the right side of the display. Thereby, the swing trajectory can be drawn larger on the display screen.

Also, when "switch" is touched, the display of the swing trajectory is switched to the display of the "face trajectory". By touching the display screen of this "face trajectory", the screen is switched between "face angle at impact" and "loft angle at impact". This screen is a still image, not a video.

This display of the face trajectory is performed by calculating the orientation of the face at intervals of 2 ms on the trainer device main body 710 side based on the data of the three-axis acceleration and the three-axis angular velocity detected at sampling intervals of 2 ms on the motion sensor 730 side. The change of plane is displayed on the screen in a display form of a set of intermittent lines. At this time, a display mode is adopted in which the center of the screen is the lowest point of the face trajectory. 2 ms is a sampling interval for drawing the direction of the face surface at the instant of impact, which is the lowest point, as shown in the figure. In the above-mentioned display mode of the swing trajectory seen from the back or top, the ball is shifted to the right so that the swing trajectory can be drawn large, but in the case of the face trajectory, the direction of the face surface before and after the impact is accurately displayed. In the sense of conveying, it is suitable to display so that the lowest point (ball impact position) is in the center. The sampling interval should be 2 ms or less, more preferably 1 ms or less.

If you touch "Switch" while "Face trajectory" is displayed, the screen will switch to "Swing data", showing "Club type", "Upswing time", "Downswing time", "Face angle at impact", and "Loft at impact". The screen switches to a screen that displays "Angle" as a numerical value.

In addition to being able to check the face angle and loft angle numerically as "swing data", by drawing the trajectory of the face surface at a sampling interval of 2ms as the face trajectory, in addition to the numerical value, you can see your swing more accurately as an image. It is possible to comprehend.

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

In the trainer device 710, the "swing trajectory" is repeatedly reproduced, but since the motion calculation has already been completed, the next swing can be executed continuously to obtain the swing trajectory, etc. It has become. Therefore, the LED lamp 732 of the motion sensor 730 is in the state of "continued green lighting". When the user needs to save, he touches "Save" before making the next swing. If there is no need to save, it is possible to swing immediately after confirming that the LED lamp 732 continues to light green.

[Arc playback mode]
Next, procedures for executing the "Arc playback mode" using the system of this embodiment will be described. The “Arc reproduction mode” is a mode for reproducing and confirming 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. After turning on the power, as shown in FIG. Then, as shown in FIG. 33B, the stored Arcs are displayed in chronological order from the newest one, so touch the Arc to be played back. Then, as shown in FIG. 33C, swing trajectory, face trajectory, and Arc are reproduced as swing data. Screen switching and the like are the same as those in the Arc mode.

[Model display]
Next, in the "Arc mode" and "Arc playback mode", the function of superimposing and displaying the "model" when displaying the "swing trajectory" will be described. To use this function, as shown in FIG. 34(A), touch "Settings" on the menu screen, then open the "Arc tab" and select "Display" as shown in FIG. 34(B). Touch , touch "Do not display sample", touch "Display" on the screen that opens, change it to "Display sample", 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 "Display model" in this way, as shown in FIG. When the swing trajectory is displayed, the model swing trajectory is superimposed and displayed. This model is based on data when a professional golfer makes a swing using this system, and is stored in advance as "model data" in the storage device of the trainer device 710 .

Even in this "example display", by touching the screen, the screen display can be switched from front → front (from slightly above) → rear → top → front → … and a model is superimposed on each screen. It is configured to be displayed.

Also, by setting to "display a model" and confirming it in the "Arc playback mode", as shown in FIG. can be utilized.

[Setting mode]
Next, the setting mode will be explained. As shown in FIG. 36A, when "setting" is touched on the menu screen, the setting screen is displayed as shown on the right side. By touching the "forward key" and "return key" on the setting screen, the setting object can be switched among "swing tab", "arc tab" and "system tab".

An operation method for changing the display mode in the "swing mode" using this "setting mode" will be described. As shown in FIG. 36(B), if you want to switch the display positions of "head speed" and "estimated flight distance" vertically, touch "display item" in the "swing tab" to display the screen shown at the bottom left. Let On this screen, when the top display item "head speed" is touched, the screen is switched to the screen on the right side. If you touch "estimated flight distance" on the switched screen, the screen switches to a screen in which "estimated flight distance", "estimated flight distance", "ball speed", and "meat rate" are arranged in order as shown on the right side. This time, touch "Estimated distance" on the second row, and touch "Head speed" on the screen that switches. rate” and the display position is changed. By touching "return" here, the settings for changing the display order are stored in the trainer device 710. FIG. After that, when the "swing mode" is activated, the display items can be displayed in a state in which the top and bottom of the display items are reversed. 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 a screen with 4 items displayed as shown in Fig. 36(C), then touch "Meat rate" and select "Do not display" on the switched screen. touch. Then, as shown on the right side, the bottom of the display items is switched to "do not display", and by touching "return" in this state, the change to the display of three items is stored in the trainer device 710. After that, when the "swing mode" is activated, a screen with three items can be displayed as shown in the second lower row. Similarly, it is also possible to set two-item display and one-item display.

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

Touch "Screen" to switch "Nice Shot Display" between "Yes" and "No", set "Nice Shot Reference Value" by entering numerical values, and switch "Right-handedness" and "Left-handedness" for "Select handedness". can be set. It should be noted that the "reference value" can be set within a limited range of "1.20 to 1.60".

When you touch "Practice mode", you can set the "upper limit of target setting distance", "lower limit of target setting distance", "green radius" by numerical input, and switch "on" or "not" for "nice on display". It has a configuration that allows The upper limit of the target setting distance can be set to 51 to 999 yards, the lower limit of the target setting distance to 50 to 149 yards, and the green radius to 1 to 50 yards.

When you touch "Flying distance factor (ball)", a club selection screen is displayed, and after selecting a club, the flying distance factor can be set by entering a numerical value within the range of 50% to 150%. . It should be noted that the "wedge" cannot be selected among the clubs in the "flying distance coefficient (ball)".

The club selection screen is also displayed when "flying distance coefficient (club)" is touched, and after selecting a club, the flying distance coefficient can be set by numerical input within the range of 50 to 150%. there is It should be noted that, in the "flying distance coefficient (club)", the "putter" cannot be selected among the clubs.

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

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

Touch "Club" to switch to the selection screen for "Club selection", "Sensor position" and "Face surface calibration". In the "Arc mode", any of "wood", "utility", "iron", "wedge" and "putter" can be selected in the "club selection".

The "sensor position" and "face calibration" have already been described. This "sensor position" and "face calibration" make it possible to improve the detection accuracy of the swing trajectory and face trajectory.

When "Display" is touched, a screen for setting switching between "on" and "off" for "doll display" and "model display" is displayed. By combining "display" and "not display" of "doll" and "model", the display mode of the swing trajectory in "Arc mode" can be changed to one of the four patterns shown.

The results of operations performed in the setting modes described above are stored in the trainer device 710 and become the setting state for each user.

[Measurement of head speed, etc.]
Next, the internal structure of the microcontroller of the trainer device 710 and arithmetic processing such as measurement of head speed and ball speed 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 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 taken into the capture register 724c when a predetermined event occurs. A periodic data storage area for storing periodic data is provided in the memory 724b, and this area consists of 110 array areas (220 bytes in total) with a width of 16 bits.

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

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

In each process executed by the first microcontroller 724, "waiting to start", "measurement in progress", "completion", and "error" are defined as measurement states (processing states), and each state is stored in the memory 724b. This 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. This state is set immediately after resetting (immediately after turning on the power), and when the trailing edge of the Doppler pulse is detected and the cycle thereof is equal to or less than a specified value, the state is changed to "measurement in progress". The state "measuring" is a state in which cycle data is being accumulated. The state "completion" is a state in which accumulation of period data is completed and the number of effective measurement data exceeds a specified value. When this state is reached, speed calculation processing is performed to check the stored data and calculate the speed. The state "error" is a state in which the accumulation of periodic data is completed, but the number of accumulated data is less than the specified number. When this state is reached, the stored data is immediately discarded, and processing (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 flow chart of FIG. Since the counter 724a is 16 bits, when the counter value reaches 65535+1, a counter overflow interrupt occurs and this processing is started.

First, in S110 (S110 is an abbreviation for step 110, and the same applies hereinafter), the number of overflow occurrences held in the memory is incremented by one. In the following S120, it is determined whether the measurement state is "waiting to start", "completed", or "measurement in progress". If the measurement state is "waiting to start" or "completed" (S120: waiting to start or completed), this process ends. On the other hand, if the measurement state is "measurement in progress" (S120: measurement in progress), the process proceeds to S130. In S130, it is determined whether or not the number of overflow occurrences has reached a specified number. This specified number of times is set to 16 times. The fact that overflow occurs 16 times means that the trailing edge of the pulse is not input for a long time of about 400 ms, and in such a case, it is necessary to get out of the "measurement in progress" state. . If the number of overflow occurrences has not reached the specified number (S130: No), the counter overflow interrupt processing is ended. On the other hand, when the number of overflow occurrences reaches the specified number (S130: Yes), the process proceeds to S140. In S140, it is determined whether or not the number of recorded data (the number of recorded periodic data) exceeds a specified number. This prescribed 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" at S150, and this interrupt process ends. On the other hand, if the number of recorded data does not exceed the specified number (S140: No), the process proceeds to S160, changes the measurement state to "error" at S160, and terminates this interrupt process.

With this process, the number of overflow occurrences is counted when an overflow occurs, and when an abnormal state such as 16 overflow occurrences occurs, the measurement is stopped at that point, and when the recorded data exceeds the specified number changes the measurement status to "Complete" and performs the speed calculation process described later, but if the recorded data does not exceed the specified number, it changes the measurement status to "Error" and discards the accumulated data. Then, a process (not shown) for returning to the "waiting for start" state is performed.

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

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

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

In S332, C is incremented by "+1", and in S334, it is determined whether or not the new incremented value of C is four. 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, resets C=0 (S336), and then proceeds to S338. At S<b>338 , the first microcontroller 724 outputs an accumulation start signal to the second microcontroller 725 . In other words, when the period is smaller than the measured value (Yes in S320) and no overflow occurs (Yes in S330) four times, it can be determined that the swing has occurred, and the accumulation start signal is output. output. The function of executing the processing steps of S320 to S338 constitutes swing discrimination means.

When the period of the Doppler signal based on the Doppler signal output by the Doppler sensor becomes a periodic pattern corresponding to the swing of the head, the swing determination means determines that there has been a swing of the head (finally Yes in S334). are doing. The periodic pattern corresponding to the swing of the head is determined in advance based on periodic patterns obtained by swinging various types of clubs by a large number of people and periodic patterns obtained when the clubs are not swung. Alternatively, for example, a periodic pattern corresponding to the user's swing may be learned and used.

After outputting the accumulation start signal, the first microcontroller 724 proceeds to S340. In this S340, the measurement state is changed to "during measurement", and the process proceeds to S350. In S350, the number of falling edges stored in the memory 724b is changed to zero. In this way, when the period of the Doppler signal output by the Doppler sensor 721 becomes smaller than a predetermined value, setting is made to start accumulating period data in the memory 724b. Therefore, in the interrupt processing at the next Doppler pulse falling edge, it is determined that "measurement is in progress" at S310, and the processing from S360 onwards is performed.

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

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

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

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

At S410, it is determined whether or not the number of recorded data in the array on the memory 22 exceeds the specified number. , the measurement state is changed to "completed" and this interrupt process ends. On the other hand, if the specified number is not exceeded (S410: No), the process proceeds to S430, where the measurement state is changed to "error", and this interrupt process ends. The specified number of recorded data in S410 is set to "32". That is, if it is determined that an overflow has occurred in the processing of S370 (S370: Yes) or if it is determined that the cycle is equal to or greater than the specified value in S380 (S380: No), the processing of S390 is not performed, and the cycle data (memory 22), the number of recorded data may be less than 110. In this case, 32 pieces are set as the number necessary for the speed calculation process in FIG. On the other hand, if this number is not exceeded (S410: No), the measurement state is changed to "error", the accumulated data is discarded, and processing (not shown) is performed to return to the "waiting for start" state. make it possible

By the Doppler pulse trailing edge detection interrupt processing as described above, when the measurement state is "completed", 33 or more pieces of data relating to the period for which the velocity is to be calculated are stored in the memory (array) 724b. .

Next, speed calculation processing will be described with reference to FIG. The velocity calculation process is started when the measurement state becomes "completed".

In S510, the moving average of the data from the beginning to the number of accumulated pieces of the periodic data accumulated in the memory 724b is calculated, and the calculation result is stored in the memory (RAM) 724b. Specifically, an arithmetic average is obtained from the four data of period data 1 to period data 4, and stored in a moving average storage array in the memory (RAM) 724b. Subsequently, an arithmetic average is obtained from the four data, period data 2 to period data 5, and stored as moving average period data in the moving average storage array in the memory 724b. In the same manner, 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 high variability are excluded. That is, if all of the four original data used to calculate the moving average in S510 are not within the range of the average value ± n%, the data is data with large variations (that is, data with low reliability of measured values). ), and the moving average value calculated from the original data is excluded from subsequent processing.

Specifically, in S520, first, the value of n is set to 12.5%, and if all the four original data are not within the range of the average value ±12.5%, the data is considered to have a large variation. As such, an 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 piece of moving average cycle data in a format corresponding to the moving average storage array, for example.

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

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

In the following S550, as a result of the exclusion process in S520, it is determined whether or not the number of data for which the exclusion flag is not set (the number of valid data) is less than 10. If the number is less than 10 (S550: Yes), the process proceeds to S560. Transition. At S560, the measurement state is set to "error", and this process ends. On the other hand, if 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. Also, in S530, when the number of data for which the exclusion flag is not set (the number of valid data) 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, minimum cycle data (corresponding to minimum cycle value=maximum frequency value=maximum speed) is searched from the moving average cycle data for which the exclusion flag is not set. In the following S580, the speed (head speed) is calculated from the minimum cycle data obtained in S570. Calculation of the speed is performed based on the following (Equation 1).

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

In the following S590, the head speed obtained in S580 is displayed on the display. For example, display like 50.0 m/s. At this time, the display of the head speed is flashed 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 displayed as a lighting display, and the process proceeds 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 the 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 teed up and actually hit, or a practice swing may be performed without setting the ball.

When the head of the golf club enters the detection range of the Doppler sensor 721 as the golf club swings, a Doppler pulse with a period corresponding to the movement speed of the head 2 is input to the first microcontroller 724, and data for each period is stored in the memory. 724b, after which the maximum velocity is measured. Then, when the measurement is performed correctly, the obtained head speed (instantaneous maximum speed) is displayed in a blinking state on the display screen 711 . 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 has been measured, and if so, the speed, depending on whether or not the speed is displayed in a blinking state.

The function of the second microcontroller 725 will now be described. The second microcontroller 725 incorporates the Doppler signal (amplified signal) output from the amplifier 722 into the second microcontroller 725 when receiving the accumulation start signal from the first microcontroller 724 in accordance with the execution of S338 described above. The digital signal is converted into a digital signal by an A/D converter, which is stored in a built-in memory (RAM) for 160 ms. When the loading is completed, FFT calculation is performed on the accumulated data in the memory to calculate the speed. As a method of calculating the speed by performing calculation by FFT, a known method used for a speed gun or the like may be used. The calculated velocity data is then 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 before and after hitting the ball, and then gradually decreases. On the other hand, when the golf club starts swinging, the ball remains stationary, so the movement speed is 0, and when the head hits it and it is launched, it moves and the speed increases. There is a lag between the peak of the head speed change and the peak of the ball speed change (the peak of the ball speed occurs with a delay). Therefore, the golf swing is detected by the swing determination means (processing algorithm for executing S320 to S328), and after the first microcontroller 724 outputs the accumulation start signal, the ball speed is determined by the second microcontroller 725. A Doppler signal (signal amplified by the amplifier 722) required for calculation is recorded.

As a result, the head speed is calculated based on the Doppler signal output by the Doppler sensor based on a data group that accumulates data relating to the period of the Doppler signal, while the ball speed is calculated based on the Doppler signal output by the Doppler sensor. It is calculated based on an A/D conversion data group in which /D conversion data is accumulated. By separating head speed and ball speed in this manner, both head speed and ball speed can be accurately measured.

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

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

When the ball is actually hit, the estimated flight distance is obtained from the ball speed and the type of club used. Specifically, the coefficient for the ball speed and the coefficient for the bed speed are set in advance for each club type (a club type-coefficient table is provided), and the coefficient corresponding to the club type is set for the ball speed or head speed. The multiplied value is the estimated flight distance. The presence or absence of the ball may be specified manually by manual operation, or may be automatically recognized by a device provided with various sensors.

In the present embodiment, the speed is calculated based on the data for each period, and the data that may cause erroneous detection is discarded, and the speed is calculated based on the final remaining reliable data. Therefore, the displayed speed is accurate and unaffected by the surrounding conditions. In addition, when the head speed is measured when the ball is actually hit, the ball flies out with great force after impact. Although it may be based on the movement of the ball, the wave number of the Doppler signal generated during the distance from the golf club head entering the detection range of the Doppler sensor 721 to the position where it is assumed to impact the ball Since the period data is stored in the memory 724b only for the prescribed number of 110 times corresponding to , 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 "meat 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 "meeting rate" is compared with the set "meeting rate reference value (1.40 in the initial setting)" to determine the size and display the "nice shot animation" in the "swing mode". "Estimated distance" is reflected in whether or not to display "nice on animation" by comparing with "target setting distance" and "green radius" set in "practice mode" be done.

Arithmetic processing in this trainer device 710 is also executed in the "Arc mode". Therefore, after confirming the swing trajectory, etc. on the screen in the "Arc mode", by returning to the menu screen and touching "Swing", it is possible to refer to the "head speed", etc. of the current swing. In "Arc mode", as a result of "model display", you can check the "head speed" etc. at that time in the "swing mode" display while correcting the swing trajectory to match the "model" swing trajectory. By doing so, it is useful for training for increasing the flight distance with a compact swing. The swing trajectory in the "Arc mode" is measured by measuring the 3-axis velocity and 3-axis angular velocity at 2 ms intervals sent from the motion sensor 730, and the calibration results of the sensor mounting position and the face surface in the setting mode. is calculated based on the results recorded by the first microcontroller 724 of the trainer device 710 as position information at predetermined time intervals and the detection results of the impact timing. The swing trajectory, face trajectory, upswing time, downswing time, face angle at impact, and loft angle at impact can be accurately calculated by the calibration function in the setting mode.

Also, when 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" and the like of the current swing are checked. After that, the user returns to the menu screen and touches "Arc" to check the swing trajectory, face trajectory, and swing data of the current swing.

It should be noted that this is the same when an operation is performed to switch the display screen between the "practice mode" and the "Arc mode".

As described above, according to this embodiment, the Doppler sensor can accurately measure the "head speed" and "ball speed", and based on this, the "estimated flight distance" can be calculated with high accuracy. Not only can the "rate" be accurately detected, but the "swing trajectory", "face trajectory" and "swing data" during the swing can also be accurately measured by performing the initial calibration or the like. Furthermore, by using the "model display", the user can accurately and accurately provide information to be referred to during training so that the user can perform a more accurate swing at a more appropriate head speed.

In this embodiment, measurement of "head speed" and "ball speed", calculation of "estimated flight distance" and "meat rate", calculation of "swing trajectory", "face trajectory" and "swing data", and notification to motion sensor 730 and communication control, detection of switch operations such as screen switching by touching the display screen, and various arithmetic processing such as switching of the display screen are performed by a computer program pre-installed in the ROM of the microcontrollers 724 and 725 of the trainer apparatus main body 710. Realized. The computer program itself may be uploaded to a server or the like as a downloadable application, and may be downloaded and installed on the trainer device main body 710 using the Bluetooth wireless communication function, or may be installed on various terminal devices or personal computers. It does not matter as a configuration to be used as

Also, the first microcontroller 724 and the second microcontroller 725 of the trainer device main body 710 in this embodiment may be configured as one controller. Conversely, a speed detection device having a microwave Doppler sensor 721 and a separate third processing device (for example, a mobile communication terminal) are provided, a motion sensor 730 is attached to the golf club as in the present embodiment, and speed The detection device is installed under the same installation conditions as the trainer device 710 in this embodiment, the detection data is transmitted from this speed detection device and the motion sensor 730 to the mobile communication terminal, and the first microcontroller in the mobile terminal device 724 and the second microcontroller 725 can also be configured as a system that performs the same arithmetic processing. In this case, the data detected by the motion sensor 730 may be received by the mobile terminal device via the speed detection device. As internal processing of the portable terminal device, a menu screen may be displayed, display screens may be switched, and settings may be changed.

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

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

For example, the sensor may be mounted on a tennis racket shaft, a baseball bat, a javelin throw, a bicycle frame, or a propeller shaft or connecting rod of an automobile engine. Further, the present invention can be applied to a mounting structure for mounting an object other than a sensor, and can also be applied to a mounting structure for mounting a sensor holder for mounting a sensor.

At the time of mounting, the mounting structure may be such that a non-slip sheet is interposed between the rubber contact portion 20 and the shaft 3a and between the rubber band 20 and the shaft 3a.

A perforated band rubber, a rubber cord with a ring, or the like may be used as the fastener, and the material may also be synthetic resin other than rubber, a coil spring, or the like.

A mushroom-shaped pin may be used as a retaining hook to prevent the housing from coming off, or a slit formed by cutting from the front side of the housing may be used. In the type of Embodiment 3, the temporary hanging portion may be formed by mushroom-shaped pins instead of hooks. It may also be configured to have a claw that has been bent.

In the type of the first embodiment, the number of openings may be four or more, or conversely two.

In the type of Embodiment 2, a slide type assisting means may be provided instead of a rotating type to reduce the force in the operation of stretching the fastener from the temporary hook to the main hook, and a large object may be attached. In such cases, these levers and sliders may be electrically operated instead of manually operated.

Further, in the first embodiment, the battery housing structure of the fourth embodiment may be employed, or the terminal cover may be attached by wrapping around to the shaft side as in the fifth embodiment.

As shown in FIGS. 45A and 45B, a mounting belt 750 may be used for the golf swing sensor 1 of Example 1 which does not have a sponge member. At this time, as shown in the illustration (A), it is not only used for the part that is hooked to the hook part of the sensor body during normal use, but in the state shown in the illustration (A), the fixing to the shaft is weak and the sensor body moves. In this case, as shown in the illustration (B), by hooking this part on the hook part of the sensor body, the length of the rubber band used for tightening becomes shorter, and the sensor body can be fixed to the shaft with a stronger force. As a result, the sensor body becomes difficult to move. In this case, in the mounting belt 750, as already explained, two types of fixing methods (if the number of hooking places is increased) can be made possible with one type of rubber band by creating a plurality of hooking places. Cost becomes cheaper than attaching a kind of rubber band. In addition, it is simpler, easier to understand, and less labor intensive to change the hooking position with one rubber band than to select and use from a plurality of rubber bands having similar shapes and different lengths. In addition, in the method shown in (B), 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 FIG. 4B but stronger than the method shown in FIG. ) on the shaft and fixing the sensor body from above increases the amount of stretching of the rubber band, so it can be fixed with an intermediate force between (A) and (B). In this case, the fixing force can be changed by changing the thickness of the rubber tube 800 . A cut 801 is provided in the rubber tube 800, and the cut 801 can be opened and attached to the shaft 3a.

Here, in the modified example of FIG. 45(C), the rubber tube 800 has an inner diameter of 12 mm or less, and is sized so that the slit 801 is open when 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 silicone rubber is superior in terms of adhesion and friction performance, and synthetic rubber is black in color. is superior to silicone rubber based on white color. The thickness of the rubber tube 800 is preferably about 3 mm.

Further, in the mounting belt 750 of the eighth embodiment, the hooks 12a to 12c may be hooked on the second partition portion 752n, and the mounting method may also be implemented such that the hooks 12a to 12c are further tightened.

Also, the golf swing trainer system 700 of the eighth embodiment may be combined with sensors of the types described in the first to seventh embodiments other than the type using the mounting belt 750 described in the eighth embodiment.

In the eighth embodiment, a silicone gel sheet may be attached to the entire surface of the sponge body 737 on the golf club side with double-sided tape. The silicon gel sheet has a surface that is less slippery than the sponge body 737, and can be fixed without slipping when the club is swung.
The total thickness of the silicon gel sheet and the double-sided tape is 0.25 mm, and the thickness of the silicon gel sheet is significantly thinner than 5 mm, which is the thickness of the sponge body. This is because the silicon gel sheet has a weaker repulsive force than the sponge body 737 when compressed. Because it will be stored away.
In this way, the surface of the golf club contacting the shaft side is provided with the first member (silicon gel sheet in the above example) that is made of a material that is relatively resistant to surface slippage and has a weak repulsive force and is thin. A second member (sponge body 737 in the above example) made of a material having a relatively strong repulsive force and having a relatively large thickness is provided on the side farther from the shaft than the first member (sponge body 737 in the above example). should be

INDUSTRIAL APPLICABILITY 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 or the like.
