Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf rangefinder for measuring the flight distance of a ball during golf play.

[0002]

2. Description of the Related Art Conventionally, the distance traveled by a ball has been visually sensed during golf play.

[0003]

However, such a method has the following problems because the accurate distance cannot be grasped. The ball flew well, or didn't fly very much,
Since I only knew it roughly, I didn't have the pleasure of being overwhelmed by the slight difference in the flight distance of the ball. Since the distance to the green was not exactly known, there were times when mistakes were made in the selection of clubs, making it difficult to establish an appropriate strategy.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a golf range finder which can accurately measure the flight distance of a ball and improves the enjoyment of golf.

[0005]

The golf rangefinder according to the present invention is as follows, which achieves the above object.
A sensor that detects vibrations associated with walking, a step counting unit that counts the number of steps by integrating the detection signals of this sensor, a counting stop switch that temporarily stops the counting of this step counting unit, and a stride that sets a stride. A setting unit, a distance calculation unit that calculates a distance by multiplying the step length set by the step setting unit and the number of steps counted by the step number counting unit, and the distance calculated by the distance calculation unit is displayed in yard units. And a display portion for operating the housing, the display portion is provided on the front surface of the housing, and the rear surface of the housing is provided with a latching portion for latching the belt of the pants on the housing. It is provided freely.

[0006]

The operation of the golf rangefinder according to the present invention is as follows. In order for the player to use the golf range finder, first, the stride is set by the stride setting unit, and the stride is hooked on the pants belt or the like by the hooking unit. And, for example, if you walk from the point where you hit the ball to the point where the ball reaches,
A value obtained by multiplying the number of steps by the stride is displayed as a flight distance on the display unit in units of yards. The player can view the display unit by rotating the housing of the golf rangefinder with respect to the hooking unit. Further, when the club is swung or the like, the sensor erroneously detects it as walking, so the counting stop switch is pressed to stop the integration of the step counting section.

FIG. 4 is a front view of the housing in which the housing is lifted from the above state. Hereinafter, a detailed description will be given with reference to these drawings.

The golf range finder 10 includes a sensor 12 for detecting vibrations caused by walking, a step count counter 14 for counting the number of steps by accumulating detection signals from the sensor 12, and a count for the step count counter 14 temporarily. A counting stop switch 16 for stopping, a stride setting unit 18 for setting a stride, and a distance calculating unit 20 for calculating a distance by multiplying the stride set by the stride setting unit 18 and the number of steps counted by the step counting unit 14. The housing 24 is provided with a display unit 22 for displaying the distance calculated by the distance calculation unit 20 in units of yards, and the front face 2 of the housing 24 is provided.
A display portion 22 is provided on the housing 4a, and a back portion 24b of the housing 24 is provided with a hooking portion 30 for hooking on a belt 28 of pants or the like so as to be rotatable with respect to the housing 24.

The sensor 12 converts changes in pressure, acceleration, etc. into electrical signals. The sensor 12 may be a pendulum type, an electromagnetic type, or the like, but any sensor 12 may be used as long as it can detect the vibration associated with walking. Step counting section 1
Reference numeral 4 is composed of a counter circuit, and the detection signal from the sensor 12 is input as a digital amount and integrated. The counting stop switch 16 is a switch, for example, provided between the sensor 12 and the step counting section 14 to prevent the detection signal from the sensor 12 from being input to the step counting section 14. The stride setting unit 18 includes an input key 40 for inputting a stride and a storage circuit (not shown) for storing the input stride. Distance calculator 20
Is composed of a multiplication circuit and multiplies the step length and the number of steps.
The display unit 22 includes a liquid crystal display element 42 and a liquid crystal display element 42.
And a liquid crystal drive circuit (not shown) for driving the. The hooking portion 30 is a hooking piece 62 bent in a hook shape.
And a hinge 64 that rotatably connects the hooking piece 62 and the housing 24. The hinge 64 has an appropriate resistance in the rotating direction in order to prevent the housing 24 from swinging.

The front face 24a of the housing 24 is shown in FIG.
Will be described. On the front surface 24a of the housing 24,
Liquid crystal display element 42 in the center, counting stop switch 1 on the right end
6, reset switch 44 at the lower right end, input key 4 at the left end
0 and the like are provided. The liquid crystal display element 42 has a stride display surface 46 on the upper left, a step count display surface 48 on the upper right, a distance display surface 50 on the lower side, a walking mark 52 on the upper end, a counting stop mark 54, etc. on the lower end. The input key 40 is provided with an addition key 56 at the top, a subtraction key 58 at the center, and a set key 60 at the bottom.

Next, a method of using the golf rangefinder 10 will be described. Since the liquid crystal display element 42 is a reflective liquid crystal shutter, “lighting” means a light-shielding state, that is, a state in which characters and the like appear, and “light-off” means a light-transmitting state, that is, a state in which characters and the like disappear. Shall be pointed out. Also,
2 to 4, for convenience of explanation, both the walking mark 52 and the counting stop mark 54 are lit, but in reality, either one of them is lit.

First, the player sets the step length by the step length setting unit 18 in the following procedure. By pressing the counting stop switch 16 for about 2 seconds, the counting stop mark 54 lights up.
When the set key 60 is continuously pressed for about 2 seconds, the stride display surface 46
Flashes. By pressing the addition key 56 and the subtraction key 58, the value is increased or decreased by "0.01" to a desired value.
When the set key 60 is continuously pressed for about 2 seconds again, the stride display surface 46 lights up and the stride is set. If the reset switch 44 is pressed for about 2 seconds while the counting stop mark 54 is lit, the step count display surface 48 and the distance display surface 50 blink. When the user releases the finger from the reset switch 44 and presses the reset switch 44 again for about 2 seconds, both the numerical values on the step count display surface 48 and the distance display surface 50 become "0".

Subsequently, the hooking piece 62 is attached to the pants (not shown).
The belt 28 by inserting it between the
Hang on. It is assumed that the ball is hit while the counting stop mark 54 is lit. When the ball is hit, the counting stop switch 54 is pressed for about 2 seconds to turn off the counting stop mark 54 and turn on the walking mark 52. When the player walks from the point where the ball is hit to the point where the ball reaches, the step count at that time is displayed on the step count display surface 48, and the value obtained by multiplying the step count by the step length is a distance display surface in yard units as a flight distance. 50 is displayed. The player can see the display unit 22 by rotating the housing 24 with respect to the hooking unit 30.

Further, in order to prevent the sensor from erroneously detecting a motion other than walking as walking, the counting stop switch 16 is pressed to count counting mark 54 except when the distance is measured.
It is desirable to turn on. In the case of the second shot, the third shot, etc., by pressing the counting stop switch 16 to turn off the counting stop mark and turning on the walking mark 52, the value is added to the display value at that time to measure the distance. I can continue.

[0015]

According to the golf rangefinder of the present invention, it is possible to prevent the movement such as the swing of the club from being detected as the number of steps by the counting stop switch and display the measured distance by the yard unit. Therefore, the flight distance of the ball can be accurately measured, and the enjoyment of golf can be improved.
