Abstract

Disclosed in the present invention is a distance measurement device for golf (1A), enabling the measurement of the distance between the player's position and the flagstick during a golf game. Measuring the distance to a flagstick by positioning a distance measurement device (1A) at a preset distance in front of the eyes causes scenery above, below and on both sides of the flagstick to enter into the field of view, making it difficult to align the base lines of the distance measurement device to the top and bottom ends of the flagstick. Distance measurement devices with housing structures incorporating view finders and the like are an unwieldy encumbrance and impractical. In the present invention, a see-through window (3A) enabling the viewing of the flagstick is formed on a card component (2A) with a thin board form; the remaining area not covered by the see-through window consists of a light exclusion section (8A); the viewer positions the card component (2A) at a preset distance (30 cm for example) away from the eyes in the forward direction, and aligns the top and bottom ends of the flagstick viewed in the see-through window (3A) to the upper guide line (4A) and lower guide line (5A), to obtain the reading of the distance to the flagstick, indicated in a numeric value by the graduation of the scale.

Description

Golf distance measuring tool

The present invention relates to a golf distance measuring tool for measuring the distance from a shot position to a flagpole on a green.

When shooting with a flagpole on the green during golf play, the distance from the shot position to the flagpole on the green is estimated by visual measurement or display of yardage, and a club corresponding to the distance is selected and shot. The distance to be measured is from several yards to about 200 yards, but the accuracy of the measurement often decreases considerably due to the influence of the fairway situation (tilt, undulation, etc.) and the surrounding landscape. Accordingly, many golfers are eagerly awaiting the practical use of a small and lightweight golf distance measuring device.

The simple distance measuring instrument for golf described in Patent Document 1 includes a holder that is elongated in the vertical direction and a strip-shaped measuring member (scale) that is slidably attached to the holder. A plurality of scale marks indicating a distance to the flagpole and a plurality of distance numerical values are marked on the measurement member. When measuring the distance from the shot position to the flagpole, the upper end of the flagpole is aligned with the reference line at the upper end of the measurement member, and the distance to the flagpole is measured from the distance value corresponding to the lower end of the flagpole.

The surveying instrument described in Patent Document 2 includes first and second arms that are openable and closable by connecting one end to a pin. First and second pointer portions are provided at the distal ends of the first and second arms, and a scale portion having a plurality of distance numerical values is formed on the second arm. When measuring the distance from the shot position to the flagpole, the opening degree of the first and second arms is adjusted so that the flagpole is sandwiched between the first and second pointer parts, and the first and second Read the distance value of the scale at the intersection of the arms.

The distance measurement measurement value scale seal for golf described in Patent Document 3 is a scale seal that is used by being attached to the outer peripheral surface of a shaft of a golf club. In this scale seal, a horizontal reference line, a plurality of scale lines based on the reference line, and a plurality of distance numerical values are described in the vertical direction. When measuring the distance from the shot position to the flagpole, the distance value is read with the arm holding the golf club extended and the lower end of the flagpole aligned with the reference line of the scale seal.

The distance measuring device described in Patent Document 4 (see FIGS. 4 and 5) includes a cylinder, a finder provided at the base end of the cylinder, and an objective window provided at the tip of the cylinder. The finder includes a reference underline made of a straight line, a reference overline made of a straight line, and a distance scale in which a plurality of distance values are marked along the reference underline. When measuring the distance from the shot position to the flagpole, the flagpole is sandwiched between the reference underline and the reference overline while looking at the flagpole through the viewfinder and the objective window, and the distance is read from the distance scale.

In addition, various distance measuring devices with a configuration incorporating an electronic device or a distance measuring device incorporating a lens or a finder in a handy case have been proposed, but the configuration is complicated and bulky, which is inconvenient to use. It lacks practicality.

Here, when the length of the flagpole is 2.2m above the ground and the length of the flagpole is measured at a position 60cm away from the eyes, the relationship between the distance to the flagpole and the length of the flagpole is as shown in the following table. become.
Distance (yard) 40 60 80 100 120 140 160 180
Flagpole length (mm) 36 24 18 14.4 12.0 10.4 9.0 8.0

In the distance measuring device for golf of Patent Document 1, since a plurality of horizontal scale marks and distance numerical values are arranged in a vertical direction on a measurement member elongated in the vertical direction, in the region where the distance to the flagpole is 100 yards or more, the above As can be seen from the table, since the interval between the plurality of scale marks is very narrow (about 2.4 mm to 1.0 mm), it is difficult to clearly display the scale marks and the distance numerical values. The scale seal of Patent Document 3 also has the same problem as described above.

Since the surveying instrument of Patent Document 2 has a configuration in which the first and second arms are connected to be openable and closable, it is bulky and expensive to manufacture. In addition, there is a problem that the operation of increasing or decreasing the opening degrees of the first and second arms is troublesome during measurement.

The distance measuring device of Patent Document 4 has a bulky structure in which a finder and an objective window are incorporated in a cylindrical body, so that it is not easy to use, lacks practicality, and is expensive to manufacture. Of the reference underline and the reference overline described in the viewfinder on the eyepiece side, it is desirable that the reference overline is a partial hyperbola, but the horizontal axis (distance indication scale) of the area of 100 m or less is long because it is described as a straight line. Therefore, the width of the finder is increased.

In addition, since the reference upper line and the reference underline are described in a transparent viewfinder, and the background on the lower and upper sides of the flagpole enters the field of view from the viewfinder, make the upper and lower ends of the flagpole match the reference upper line and the reference underline. Difficult to generate errors and difficult to measure quickly.

Accuracy can be improved. Since the card member 12 has a simple structure in which only the upper and

lower instruction lines

14 and 15 and the

distance instruction graduations

19 and 19a are described, the manufacturing cost can be reduced. The distance indicating scale 19a may be omitted. Other operations and effects are substantially the same as those of the first embodiment except for the operation and effects of the light shielding portion.
