Description

Sensor installation structure of golf measuring instrument {IMPROVEMENT IN SENSOR STRUCTURE FOR USE IN PORTABLE MEASURING DEVICE FOR GOLFERS}

The present invention efficiently measures and manages the hit speed of the golf club head and the flying distance of the hit golf ball when hitting the golf ball with a golf club, such as in the practice range, to help improve the personal record and performance of golf. It relates to a sensor installation structure of the golf measuring device designed to improve the accuracy of the measurement by improving the installation structure of the measurement sensor in the golf measuring device configured to give.

In golf, the speed at which the ball strikes the golf club and the distance of the ball is one of the important factors that affect the performance and the result of the golf player. Can only be obtained by repeating many exercises and corrections.

Such golf practice can be achieved through rounding on a real golf course, but it is usually performed in a golf practice range equipped with facilities capable of concentrating, repeatedly hitting, correcting posture and keeping records in a short time. Because the driving range is equipped with the necessary facilities in a limited space to practice golf, the exerciser has a limitation in that it is difficult to determine how far the ball is actually flying. In order to compensate for this, some conventional golf driving ranges have a measuring unit installed at each predetermined practice site in the driving range, and the hitting speed and the distance of the ball measured by the measuring unit are displayed through a central computer. This is to inform the exerciser who wants to know the result of his practice.

However, according to the conventional technique as described above, it is difficult for a practitioner who practices golf in the golf practice range to immediately check the exact result of each stroke. Not only can it be dependent on the batting practice, it is difficult to meet the desire to achieve more concentration, more efficient practice and correction within a limited time, and it is also possible to measure the hitting record flexibly in response to each individual's hitting characteristics, habits and driving conditions. Management was also a difficult problem.

The present inventors have applied for the domestic utility model registration application Nos. 97-28223 and 97-28288 for the golf measuring device and golf recorder designed to solve this problem, the golf measuring device introduced here When practicing golf in a place such as a golf practice field, the golfer can immediately check the hit speed and the distance of the ball for each time the golf ball is hit.This allows more focused and efficient golf within a limited time and space. It is configured to practice and strike attitude correction.

By the way, the golf measuring instrument of this source appeared to have some problems in the measurement accuracy as a result of actual use, briefly explain the problem of the source design in order to help the present invention.

Figure 1 shows a conventional sensor installation structure and its measuring action applied to the aforementioned golf measuring device, which is typically an infrared sensor suitable for application to such a golf measuring device for the purpose of the golf First and second sensors 2 and 3 spaced apart from each other on the measurement head 1 of the measuring instrument at a predetermined interval from side to side, and the first and second sensors 2 and 3 are respectively It is composed of a combination of the infrared light emitting portion 4 and the light receiving portion 5 arranged in parallel to each other in the right and left or up and down, and in front of the light emitting portion 4 and the light receiving portion 5 of the cylindrical light guide passage (6) ( 7) is formed by forming each. The conventional sensor configured as described above has a golf practice in front of the light emitting unit 4 of the first sensor 2 and the light emitting unit 4 of the second sensor 3, respectively, in the state in which infrared light is emitted forward. When swinging the golf club to hit the golf ball by itself, the golf club head 8 moves in the direction of the arrow, and the golf club head 8 first reflects the infrared rays emitted from the light emitting part 4 of the first sensor 2 to reflect the golf club head 8. The reflected light is incidently detected by the light-receiving portion 5 of the first sensor 2, and then infrared rays emitted from the light-emitting portion 4 of the second sensor 3 hit the golf club head 8 and are reflected to reflect the reflected light. Incident detection is detected by the light receiving unit 5 of the second sensor 3. At this time, the detection of the reflected light at each of the light receiving units 5 of the first and second sensors 2 and 3 depends on the traveling speed of the golf club head 8 and the distance between the first and second sensors 2 and 3. It occurs with a corresponding parallax, from which the speed of the golf ball strike moment of the golf club head 8 and the flying distance of the hit golf ball can be calculated.

However, the infrared rays emitted from each of the light emitting portions 4 of the sensors 2 and 3 do not go straight straight but have spreadability as illustrated in Fig. 1, so that the golf club head 8 proceeds along the direction of the arrow. For example, in the case of the first sensor 2, since the infrared rays are spread in a considerable width when the infrared rays from the light emitting portion 4 meet, the golf club head 8 has an irregular reflective surface. Infrared light from the light emitting portion 4 reflected at the point A may be incident to the light receiving portion 5 through the simple cylindrical light guide path 7, and of course, the light emitting portion 4 reflected at the point B may be detected. In some cases, the infrared light from the light-receiving unit 5 is incident on the light-receiving unit 5, and in the case of the second sensor 3, the infrared light from the light-emitting unit 4 reflected at point C is also incident-detected on the light-receiving unit 5. From the light emitting portion 4 reflected at point D. It is possible that when the outer optical rotation is detected, enters the light-receiving unit (5).

Therefore, when practicing golf in front of a golf measuring device having such a conventional sensor mounting structure, if the golf club head 8, which the practitioner wielded as an example, is reflected at the point A of the first sensor 2, When the first sensor (2) in front of the first sensor (2) in front of the second sensor (3) is detected by the light reflected from the position of the point D, the golf club head (8) Is measured at a slower speed than actually before the two sensors (2) and (3), and as another example, the golf club head (8) is first reflected by the light reflected at the point B in the first sensor (2). If it is sensed that the sensor 2 has passed in front, and then the second sensor 3 detects that the light has passed through the front of the second sensor 3 with the light reflected at the point C, the golf club head 8 The speed through both sensors (2) and (3) is measured faster than it actually is, The measurement error will occur, and this measurement error will cause the golf practitioner to make an error in his or her hit record measurement management, and thus cause the golfer to lose confidence in the golf measuring instrument.

Therefore, the present invention is devised to provide a sensor installation structure of a golf measuring device that can be improved more effectively to solve the above-mentioned problems as described above to make the required measurement during golf practice more accurately.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

Figure 2 is a planar cross-sectional view showing the main portion of the golf measuring device to which the sensor mounting structure of the present invention is applied, wherein reference numeral 1 denotes a measuring head disposed at the tip of the relevant golf measuring device.

As illustrated herein, the present invention includes first and second sensors 2 and 3 spaced apart from each other on the measurement head 1 at a predetermined interval from side to side, and the first and second sensors 2 (3) A combination of an infrared light emitting unit 4 and a light receiving unit 5 arranged in parallel with each other in the right and left or up and down directions, respectively, the front of the light emitting unit 4 and the light receiving unit 5 In the sensor mounting structure of the golf measuring device in which the guide passages 6 and 7 are formed, the first light shielding portion 9 and the first light shielding portion at the tip of the light guide passage 7 in front of the light receiving portion 5 are provided. A second light shielding portion 11 disposed at a position closer to the light receiving portion 5 than the first portion 9 and forming a light incidence gap 10 at an appropriate interval between the first light blocking portion 9; The inner circumferential surface of the passage 7 is formed by forming a continuous mountain pleat 12.

FIG. 3 shows a preferred example for installing and providing the first and second light blocking portions 9 and 11 and the pleats 12 inside the light guide passage 7 in front of the light receiving portion 5. A semi-cylindrical passage member 13 having a first light shielding portion 9 formed at the tip portion and a continuous mountain fold 12 formed on the inner circumferential surface thereof, and a second light shielding portion 11 formed at the tip portion thereof, and the passage member on the inner circumferential surface thereof. A semi-cylindrical passage member 14 having a continuous mountain pleat 12 as in (13) is provided, and the two passage members 13 and 14 are combined in the illustrated manner to provide a light guide passage 7 ) It is to be assembled and installed inside. The reason for this is that the first and second light blocking portions 9 and 11 and the continuous mountain pleats 12 are integrally formed on the inner wall of the guide passage 7 because it is very difficult due to the requirements of injection manufacturing. By using a bar, rubber material or synthetic resin material, the passage members 13 and 14 may be separately manufactured, and then assembled into the guide passage 7 so that the measuring head 1 may be manufactured in any way. The desired light shielding portions 9 and 11 and the pleats 12 can be simply installed inside the guide passage 7 without causing difficulty.

The present invention configured as described above has the position before the E point when the head of the golf club swinged by the golf practitioner moves in the direction of the arrow from the front of the measuring head 1 as shown in FIG. Infrared light from the light emitting portion 4 which hits the golf club head and is reflected at the position after the F point is reflected by the first light blocking portion 9, the second light blocking portion 11, and the pleats 12 by the reflective action. 5), and in the case of the front of the second sensor 3, the infrared light from the light emitting portion 4 that hits the golf club head and is reflected at the position before the G point and the position after the H point is also described above. Due to the action of the first light blocking portion 9, the second light blocking portion 11, and the wrinkles 12, the light receiving portion 5 may not be reached.

Therefore, the sensor mounting structure of the present invention has a light emitting part that hits the golf club head at a position between E point and F point, which is a substantially center position in front of the light receiving part 5 in front of the first sensor 2. Only the infrared light from (4) is made to be detected to reach the light receiving portion 5 through the light incidence gap 10, and also in the case of the second sensor 3 in front of the light receiving portion 5 almost in the center. Since the infrared light from the light emitting portion 4 reflected by hitting the golf club head at the position between the G point and the H point is made to be detected to reach the light receiving portion 5 through the light incidence gap 10, the conventional measurement is performed. This greatly reduces the error and allows for very accurate measurements.

Therefore, the present invention provides a more accurate measurement and management of the golf ball hitting speed and the hitting distance of the hitter during the golf practice by the configuration, operation as described above, thereby improving the reliability of the use of the related golf measuring device It's a new and useful design that can help you improve your personal record and performance.
