Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf simulation device for measuring the movement of a club head when the golf club swings.

[0002]

2. Description of the Related Art As the above golf simulation apparatus, for example, the technology disclosed in Japanese Utility Model Publication No. 62-45735 is known. This device detects the movement of the putter head when the putter is swung, and processes the detected signal to display the movement trajectory of the putter in segments. The configuration of the device disclosed in this publication will be briefly described below.

On a flat plate on which putting is actually performed, three sensor rows are provided at predetermined intervals along the moving direction of the putter head and at right angles to the moving direction. Each sensor row is provided with seven sensor units at a predetermined interval, and each sensor unit has one light projector along the moving direction of the putter head and the light emitted from this light projector and reflected by the passing putter head. One photodetector is arranged to detect the emitted light.

The ball is placed on the reference line between the first sensor row and the second sensor row, and the ball is putted. The central sensor unit of each sensor row is located on the reference line, and three sensor units are located on each side of each central sensor unit. And
In the putting operation, the state of the putter head that has successively passed through each sensor row is displayed for each sensor row. That is, the deviation of the putter head from the reference line and the amount of inclination of the face when passing through each sensor row are displayed in segments.

[0005]

As described above, the projector and the receiver of each sensor unit in each sensor array are arranged along the moving direction of the putter head. However, in such a sensor unit configuration, it is not possible to close the interval between adjacent sensor units in each sensor row. This is because if the distance between the sensor units is narrowed, the light receiver may detect (interfere with) the light emitted from the light projector of the adjacent sensor unit.

Therefore, according to the conventional golf simulation device, the distance between the light receivers (measurement points) becomes large, and the deviation amount of the club head from the reference line and the inclination amount of the face at the reference line are rough results. I can only get it. That is, when the golf club is swung, the practitioner cannot recognize the accurate shift amount of the club head in each sensor row from the reference line and the accurate tilt amount of the face in the reference line.

According to the present invention, when a golf club is swung, a sensor row through which the club head passes measures an accurate deviation amount from the reference line of the club head and an accurate inclination amount of the face at the reference line. An object of the present invention is to provide a golf simulation device capable of performing the above.

[0008]

In order to solve the above-mentioned problems, a golf simulation apparatus of the present invention has a plurality of sensor units arranged at predetermined intervals in a direction orthogonal to a reference line through which a club head passes. Each of the sensor units constituting the sensor row detects a light projector and light emitted from the light projector and reflected by the club head, and is arranged on the same line orthogonal to the reference line. In a sensor array including a plurality of light receivers arranged and having the plurality of sensor units, the light projector of each sensor unit receives the reflected light from the club head only on the plurality of light receivers of the sensor unit. It is characterized in that it is arranged in a position.

[0009]

Each sensor unit includes one light projector and a plurality of light receivers arranged on the same line orthogonal to the reference line. Since the light emitted from each sensor unit and reflected by the club head is arranged so that the light emitted from the sensor unit is incident only on the plurality of light receivers, the distance between the sensor units forming the sensor row is increased. Can be made dense without interfering. That is, in each sensor row,
Since the number of measurement points increases and the distance between them increases, the sensor array through which the club head passes accurately measures the amount of deviation of the club head from the reference line and the amount of inclination of the face at the reference line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the accompanying drawings. FIG. 1 is a perspective view showing a configuration of a sensor unit 10 by enlarging a part of one sensor row in the golf simulation device of the present invention. The sensor unit 10 is projectingly provided on a substrate 2 provided on a flat plate (not shown), and one sensor unit emits light from the projector 11 at the center and from the projectors 11 on both sides thereof.
It is composed of a pair of light receivers 12 for receiving the light reflected by a club head (not shown). Projector 11 and photoreceiver 12 which constitute the sensor unit 10.
Are arranged on a line orthogonal to the moving direction (reference line) of the head shown by the arrow, and the sensor units 10 are arranged at predetermined intervals along this direction, whereby one sensor row is Composed.

The substrate 2 provided with the sensor array in this way
Are covered by the base plate 3 on which a reference line is drawn. A light projecting hole 5 for the light projecting device 11 and a light receiving hole 7 for the light receiving device 12 are formed in the base plate 3 so as to correspond to the sensor units forming the sensor array provided on the substrate 2. The reflected light is emitted and received through these holes.

FIG. 2 shows the overall structure of a golf simulation apparatus having the sensor unit 10 having the above structure. A start sensor row S, a sensor row A, a sensor row B, and a sensor row C, which are orthogonal to a reference line, are arranged at predetermined intervals on the flat plate 1 having the substrate and the base plate. Each of the sensor arrays A to C includes eight sensor units 10 (A1 to A8, B1 to B1) having a configuration shown in FIG. 1 in a direction orthogonal to the reference line at predetermined intervals.
8, C1 to C8) and are arranged symmetrically with respect to the reference line. In addition, the start sensor row S
Is four sensor units 10 having the configuration shown in FIG. 1 at predetermined intervals in the direction orthogonal to the reference line (S1 to S4).
I have it. Since the start sensor row S detects passage of the club head and generates a detection start signal to each of the sensor rows A to C, the distance between the sensor units can detect passage of the club head. The degree is enough. Further, in the figure, only some of the sensor units are denoted by the reference numerals corresponding to those in FIG.

When actually practicing with this apparatus, the practitioner makes a swing along the reference line or actually hits the ball. At this time, the golf ball is placed on the reference line between the sensor rows AB or between the sensor rows BC, and is placed on the tee 15 inserted on the reference line depending on the club used. In the figure, the control means for processing and calculating the signals detected by the photodetectors of the sensor units in each of the sensor rows A to C is omitted, but the sensor rows are detected by each sensor row,
The information processed and calculated by the control means is displayed on the display device 20. In the display device 20, for example, as shown in the figure, a reference line is copied on the display, and the position of the sweet spot of the head, the state of the face and the head speed at the position of each sensor row are displayed or calculated. It is configured to display the flight distance, directionality, etc. of the ball.

As described above, according to the structure of the sensor unit shown in FIG. 1, since the light receivers 12 for detecting only the light emitted from the light projector are arranged on both sides of the light projector 11 of the sensor unit, Even if the intervals between the units are made very close to each other, the light receiver does not detect the light emitted from the light projector of the adjacent sensor unit. That is, since the number of measurement points is increased and the distances between the adjacent sensor units do not interfere with each other and the distances between the sensor units are close to each other, the deviation of the club head from the reference line in the sensor row and the inclination of the face at the reference line are accurately measured. It will be possible.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made. For example, if two light receivers are densely arranged on both sides of the light projector shown in FIG. 1 to form a sensor unit, the number of measurement points can be further increased. Also, FIG.
The sensor unit may be configured by shifting the light projector 11 shown in FIG. In this case, it is possible to dispose a new light receiver between both the light receivers 12. Further, the number of sensor rows and the configuration of the start sensor row in the golf simulation device shown in FIG. 2 can be modified as appropriate.

[0016]

As described above, according to the present invention,
Since it is possible to increase the number of measurement points and make the intervals close without interfering with each other in the sensor row forming the sensor row, when the golf club swings, the sensor row passing through the club head is It becomes possible to measure an accurate deviation amount from the reference line and an accurate inclination amount of the face at the reference line.
