Description

Technical Field

[0001] The present invention relates to a golf distance measuring device for providing the distance between a measurement target and a target point.

Background Art

[0002] Golf is a sport played on an 18-hole course, with the goal of putting the golf ball into the cup on the green from the tee shot of each hole.

[0003] In such golf, in order to select a club suitable for each shot, it is very important to accurately grasp the distance from the current position where the golf ball is located to the target point (such as the hole cup or the flag on the cup).

[0004] Normally, a golfer asks a caddie for the distance from the current position to the target point and selects a golf club based on that.

[0005] However, depending on the experience and ability of the caddie, there is a problem that the distance heard from the caddie is different from the actual distance.

[0006] Moreover, these days, as the usage fees of golf courses are soaring, there are an increasing number of golf courses that offer the option of not using a caddie, or even public golf courses that do not have caddies at all.

[0007] As a result, various types of golf distance measuring devices have been developed to measure the distance from the current position to the target point.

[0008] For example, there are golf distance measuring devices that utilize GPS technology, ultrasonic technology, laser technology, etc.

[0009] Below, the usage methods of these traditional golf distance measuring devices will be explained in detail.

[0010] First, take off and move while riding on a trolley.

[0011] Then, walk to the current location where the golf ball is located and measure the distance from the current location where the golf ball is located to the target point.

[0012] After that, return to the trolley, select a golf club suitable for the measured distance, return to the current position and play golf.

[0013] Alternatively, after moving by trolley, estimate the approximate distance and select 2 to 3 golf clubs that are judged to be suitable for moving to the current location where the golf ball is located.

[0014] Then, after measuring the distance from the current location to the target point, select the optimal club from the 2 to 3 clubs and hit the ball.

[0015] Then, return to the trolley with 2 to 3 golf clubs.

[0016] As a result, when using a conventional golf distance measuring device, the user had to repeatedly travel back and forth by trolley from the current location and carry 2 to 3 heavy golf clubs from the trolley to the current location.

[0017] As a result, as the hole progresses, the golfer's stamina rapidly decreases, and the farther the distance from the trolley to the position of the golf ball, the worse the situation becomes.

[0018] There is also a problem that the play of golf is excessively delayed.

[0019] Therefore, various types of golf distance measuring devices have been proposed conventionally.

[0020] For example, Patent Document 1 and Patent Document 2 disclose devices that calculate the distance using GPS.

Embodiments for Carrying Out the Invention

[0027] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0028] In FIG. 1, reference numeral 1 indicates a golf distance measuring device according to the present invention.

[0029] This golf distance measuring device 1 includes a distance measuring unit 10, an angle measuring unit 20, an inclination angle measuring unit 30, a data calculation unit 40, a display unit (described later) 100, and a housing (not shown) equipped with these, and is configured to be easily portable and operable with one hand.

[0030] As shown in FIG. 2, this golf distance measuring device 1 is configured to provide the calculated distance BT between the measurement target B and the target point T to the user M of this golf distance measuring device 1, such as a golfer, who is at a location away from the measurement target B.

[0031] For example, the measurement target B may be a golf ball, and the target point T may be the target point to which the golf ball is shot or the flag of the hole cup.

[0032] The distance measurement unit 10 is configured to measure the target point distance MT from the user M to the target point T and the measurement target distance MB from the user M to the measurement target B.

[0033] Therefore, the distance measurement unit 10 can include various sensors such as a GPS sensor and a laser sensor. However, in this golf distance measurement device 1, it includes a laser sensor that does not require an absolute position, and is configured to measure a straight-line distance using the transmission and reception time of this laser.

[0034] Also, in some cases, a corrected distance reflecting the inclination angle described later is used for this straight-line distance.

[0035] The angle measurement unit 20 is configured to measure an angle (included angle) a included between the target point distance MT of the target point T and the measurement target distance MB of the measurement target B with the user M as the center.

[0036] Therefore, the angle measurement unit 20 can be configured to include various sensors such as a gyro sensor and a geomagnetic sensor.

[0037] For example, in the case of a gyro sensor, the included angle a is measured by accumulating the angles of information regarding the left and right movements.

[0038] Furthermore, the data calculation unit 40 is configured to calculate, by using trigonometry, the calculated distance BT between the target point T and the measurement target B from the target point distance MT, the measurement target distance MB, and the included angle a included therebetween.

[0039] Specifically, the mathematical formula (1) using trigonometry is as follows.

[0040] BT = √{MT2 +MB 2 -2×MT×MB×cos(a)} ··· Equation (1)

[0041] Next, an actual usage example of this golf distance measuring device 1 will be described.

[0042] First, after a golfer (user) M hits a tee shot, they get on a cart and move close to the golf ball (measurement target) B.

[0043] Next, at a position where the golfer M can see the flag (target point) T inserted into the hole cup and the golf ball B near the cart, the golfer M first takes a picture of the flag T and measures the target point distance MT between the golfer M and the flag T.

[0044] Next, the golf distance measuring device 1 is rotated left and right to accumulate the angle, and the measurement target distance MB between the golfer M and the golf ball B is measured.

[0045] From the target point distance MT measured in this way, the measurement target distance MB, and the included angle a between the target point distance MT of the target point T centered on the golfer M and the measurement target distance MB of the measurement target B, the distance (calculated distance) BT between the golf ball B and the flag T is calculated and provided by calculation.

[0046] According to this golf distance measuring device 1, it is not necessary to measure the distance BT from the point where the golf ball B is located to the flag T. That is, even at a position away from the golf ball B, the distance (calculated distance) BT between the golf ball B and the flag T can be accurately measured by calculating it by calculation without any limitation on that position.

[0047] As a result, the golfer M does not need to unnecessarily travel back and forth between the cart and the golf ball B with a heavy golf club as in the past.

[0048] In the above example, the golfer M can measure the calculated distance BT from the golf ball B to the flag T near the cart and select only a suitable golf club.

[0049] Therefore, the physical strength of golfer M is maintained well, it becomes easier to demonstrate skills, and the playing time also increases, so golf can be enjoyed more.

[0050] Next, with reference to FIG. 3, a method for measuring the compensation distance between the measurement target B and the target point T using the golf distance measuring device 1 will be described.

[0051] This golf distance measuring device 1 further includes an inclination angle measuring unit 30 for measuring a target point inclination angle b1 between the target point distance MT and the horizontal plane O and a measurement target inclination angle b2 between the measurement target distance MB and the horizontal plane O.

[0052] This inclination angle measuring unit 30 can include various sensors such as an acceleration sensor.

[0053] In addition, the data calculation unit 40 additionally calculates the vertical height h between the measurement target B and the target point T based on the target point distance MT, the measurement target distance MB, the target point inclination angle b1, and the measurement target inclination angle b2 using trigonometry.

[0054] The vertical height h between the measurement target B and the target point T is calculated using the following formula (2).

[0055] h1 = MT × sin(b1) h2 = MB × sin(b2) ··· Formula (2) h = h1 + h2

[0056] At this time, h1 is the height between the target point T and the horizontal plane O, and h2 is the height between the measurement target B and the horizontal plane O.

[0057] This height h can be calculated by the following formula when measuring the target point distance MT and the measurement target distance MB. Horizontal difference of BT = √BT 2 -h 2 = m Compensation distance of BT = m + h

[0058] The golf distance measuring device 1 can provide a practical compensation distance for BT by calculating the distance BT, height h, and horizontal distance m between the object B and the target point T.

[0059] Next, FIG. 4 shows a flowchart illustrating the measurement method of the golf distance measuring device 1.

[0060] The parts described in the above-described golf distance measuring device 1 are omitted to avoid duplication.

[0061] The measurement method of the golf distance measuring device 1 provides the calculated distance BT between the measurement object B and the target point T to the user M located at a position away from the measurement object B, and includes a distance measurement step S10, an angle measurement step S20, an inclination angle measurement step S30, and a data calculation step S40.

[0062] In the distance measurement step S10, the target point distance MT from the user M to the target point T and the measurement object distance MB from the user M to the measurement object B are measured.

[0063] Next, in the angle measurement step S20, the included angle a between the target point distance MT of the target point T centered on the user M and the measurement object distance MB of the measurement object B is measured.

[0064] Also, in the data calculation step S40, the calculated distance BT between the measurement object B and the target point T is calculated using trigonometry from the target point distance MT, the measurement object distance MB, and the included angle a between them.

[0065] Note that in the measurement method of the golf distance measuring device 1, the above steps do not necessarily have to be executed in numerical order.

[0066] For example, it is desirable that the distance measurement step S10, the angle measurement step S20, and the inclination angle measurement step S30 be executed simultaneously.

[0067] Next, FIG. 5 shows an actual example in the display unit 100 of the golf distance measuring device 1.

[0068] Also, FIG. 6 is a diagram showing a first method of using the actual example of FIG. 5, and FIG. 7 is a diagram showing a second method of using the actual example of FIG. 5.

[0069] First, referring to FIG. 5, the display unit 100 of the actual golf distance measuring device 1 is configured to display the measurement target (measurement target B or target point T) 110, the icon 120 of the compensation mode, the straight-line distance or compensation distance 130 of BT, and the distances 140 of MT and MB.

[0070] The golf distance measuring device 1 includes a normal mode (distance measurement for the user) and a mate mode (distance measurement for a third party), and can set another mate mode icon 150 for the mate mode to notify the user that it is in the state during distance measurement for a third party and that the corresponding distance display is different from the normal mode.

[0071] The actual usage methods of this golf distance measuring device 1 include, for example, a first usage method of using the mate mode individually, and a second usage method of using the mate mode after measuring the user's distance in the normal mode.

[0072] Specifically, in the first usage method, first, enter the mate mode by a designated button (not shown) or a designated operation provided on the golf distance measuring device 1.

[0073] To indicate that the mate mode has been entered, as shown in FIG. 6(a), the mate mode icon 150 becomes active, and one side 152 of the icon 150 blinks to measure the target object first.

[0074] When the measurement of the target point T is completed, as shown in FIG. 6(b), the target point distance (MT) 132 between the user M and the target point T is displayed, and the other side 154 of the icon 150 blinks to indicate that the measurement of a third party (accompanying golfer) is to be performed.

[0075] When the measurement of the third party is completed, as shown in FIG. 6(c), the target point distance (MT) 132 between the third party and the target point T, the target point distance (MT) 132 between the user M and the target point T, and the distance 134 between the user M and the third party are displayed on the display unit 100.

[0076] Also, according to the second usage method, first, as shown in FIG. 7(a), the result when the object is measured in the normal mode is displayed. Of course, it may vary depending on the manufacturer.

[0077] In the actual golf distance measuring device 1, the azimuth mode and the compensation mode are combined and adopted.

[0078] When this mode is activated, the icons 120 and 150 are displayed simultaneously (see FIG. 7(b)).

[0079] The slope mode is a function that provides a corrected distance reflecting the difference in height between the measurement object and the target object. Usually, an acceleration sensor is used to calculate the inclination angles between the measurement position (user M), the measurement object B, and the target point T.

[0080] When this mode is activated, the icons 120 and 150 are displayed simultaneously (see FIG. 7(b)).

[0081] Measurement is performed according to the procedure of the first method, and the final result is as shown in FIG. 7(b).

[0082] 130 indicates the compensated distance of BT, 142 indicates the compensated distance of MT, and 144 indicates the compensated distance of MB.

[0083] Thus, in this golf distance measuring device 1, the actual distance or the compensated distance of the calculated distance BT between the measurement target B and the target point T is calculated.

[0084] That is, this measurement method includes the steps of setting the golf distance measuring device 1 to either the normal mode or the mate mode, measuring the target point distance MT from the user M to the target point T, measuring the measurement target distance MB from the user M to the measurement target B, measuring the angle (included angle) a between the target point distance MT and the measurement target distance MB centered on the user M, and calculating and calculating the calculated distance BT between the measurement target B and the target point T from the target point distance MT, the measurement target distance MB, and the included angle a using the trigonometric method. In the step of setting to the mate mode, when the icon 150 of the display unit 100 of the golf distance measuring device 1 is activated, one side 152 of the icon 150 blinks to guide the user M to measure the target point distance MT. After the target point distance MT is measured in the step of measuring the target point distance MT, the other side 154 of the icon 150 can blink to guide a third party to measure the target point distance MT.

[0085] Also, in the step of measuring the target point distance MT, after setting the golf distance measuring device 1 to an individual normal mode, a plurality of target point distances MT can be measured.

[0086] According to the above configuration, this golf distance measuring device 1 provides the calculated distance BT between the golf ball (measurement target) B and the target point (target) T to the user M located at a position away from the place where the golf ball B is located. It includes a distance measuring unit 10 that measures the measurement target distance MB from the user M to the measurement target B and the target point distance MT from the user M to the target point T, an angle measuring unit 20 that measures the angle (included angle) a between the target point distance MT of the target point T and the measurement target distance MB of the measurement target B centered on the user M, and a data calculation unit 40 that calculates and calculates the calculated distance BT between the measurement target B and the target point T from the target point distance MT, the measurement target distance MB, and the angle a using the trigonometric method.

[0087] Accordingly, without using a system such as GPS, the calculated distance BT from the measurement target B to the target point T can be measured at a location away from the measurement target B while having a simple and easy configuration.

[0088] That is, the calculated distance BT from the measurement target B to the target point T such as the hole cup can be measured not at the current position where the golf ball (measurement target) B is located but at another position such as near the cart.

[0089] The disclosure regarding the present invention described above can be summarized at least in the following matters.

[0090] That is, the golf distance measuring device according to the present invention is a golf distance measuring device for providing a calculated distance between a measurement target and a target point, including a distance measuring unit for measuring a target point distance from a user to the target point and a measurement target distance from the user to the measurement target, an angle measuring unit for measuring an angle between the target point and the measurement target centered on the user, and a data calculation unit for calculating and calculating the calculated distance between the target point and the measurement target using trigonometry based on the target point distance, the measurement target distance, and the angle.
