Description

TECHNICAL FIELD The present invention relates to a golf ball retrieval tool used for retrieving a golf ball from a hole cup buried in a putting green.

When taking out a golf ball from a hole cup on a putting green, it is necessary to bend or stoop at the waist to pick up the golf ball in the cup with one's fingers, which puts strain on the lower back, knees, and the like. Due to rule revisions, putting can now be done without removing the pin (flagstick), which has narrowed the space inside the cup, making it even more cumbersome to remove the golf ball from the cup.

In order to deal with this problem, Patent Document 1 discloses that a cylindrical shaft member is slidably inserted into a flagpole, a plate member on which a golf ball is placed is fixed to the lower end of the shaft member, and a hook member is attached to the upper end of the shaft member. A ball lifting device with a fixed ball has been proposed. When a club is hooked onto the hook member and pulled up, the plate member comes out of the hole cup, and the golf ball rolls onto the green due to the inclined surface of the plate member. The shaft member, hook member, and plate member all have a split and mating structure so that they can be attached to the flagpole regardless of the presence of a heral. Further, the axial length of the shaft member is about 500 mm, and the hook member fixed to the upper end and projecting horizontally does not affect the behavior of the ball during putting.

There is. On the upper surface of the sounding body 14, that is, on the flat upper surface 14b of the support base 10, a golf ball ejector 18 is placed, which is inserted from the ferrule 16 side before the pin 6 is fixed. Note that the pin 6 means the whole including the ferrule 16.

As shown in FIG. 2, the golf ball extractor 18 includes an insertion hole 20a through which a pin 6 erected in a hole cup 4 buried in the putting green 2 is inserted from its lower end side (ferrule 16 side). A circular ball receiving plate 20 is placed on the supporting base 10 to be supported, and a ball receiving plate 20 is fixed to the lower surface of the ball receiving plate 20 at a position offset from the center of the ball receiving plate 20, and when placed on the supporting base 10. a tilting member 22 for tilting the ball receiving plate 20, and when the first end region 20b of the ball receiving plate 20 on the tilting member 22 side is pressed from the upper side of the hole cup 4 toward the lower side, The golf ball 24 (see FIG. 1) resting on the second end region 20c of the ball receiving plate 20 on the opposite side to the tilting member 22 is rotated by the ball receiving plate 20 using the tilting member 22 as a fulcrum. It has a flip-up structure. That is, the tilting member 22 is provided biased only to one side in the radial direction on the lower surface of the ball receiving plate 20, so that when the ball receiving plate 20 is placed on a flat surface, the ball receiving plate 20 is inclined. There is.

The tilting member 22 is supported on the support base 10 at a plurality of locations (here, two locations) spaced apart in a direction (here, orthogonal) to the radial direction (arrow X direction) of the ball receiving plate 20 (here, orthogonal). It has a configuration that makes contact with the stand 10. That is, the inclination member 22 has a length extending in the direction of the arrow Y, and includes a rectangular fixing piece 26 fixed to the lower surface of the ball receiving plate 20, and a rectangular fixing piece 26 that extends from both ends of the fixing piece 26 to the bottom of the hole cup 4. It is provided with a pair of abutting pieces 28, 28 extending toward the side and having a lower end 28a having an arc shape. The lower end 28a of each contact piece 28 has a semicircular shape. In this embodiment, the inclination member 22 is formed by bending a metal plate. It may be formed by integral molding or die-casting using resin.

A side edge 26a of the fixing piece 26 on the insertion hole 20a side has a curved recess 26b along the curvature of the insertion hole 20a, and the fixing piece 26 is arranged close to the insertion hole 20a (see FIG. 3(a)). Two screw holes 26c are formed at intervals in the direction of the arrow Y in the fixed piece 26, and correspondingly, a screw insertion hole 20d is formed in the ball receiving plate 20. It is fixed to the lower surface of the plate 20 with two screws 30. The tilting member 22 may be fixed to the ball receiving plate 20 by welding or an adhesive (including adhesive, double-sided tape, etc.). The upper surface of the first end region 20b of the ball receiving plate 20 is provided with a plurality of (three in this case) convex portions to suppress slipping when pressed with a pressing tool such as the grip 34a of the club 34 (see FIG. 4). 32 is formed. Note that here, a case is shown in which the tilting member 22 is fixed to the lower surface of the ball receiving plate 20 with two screws 30, but in addition to this, the tilting member 22 may be fixed to the lower surface of the ball receiving plate 20 by spot welding, etc. Fixing by other means is also possible.

An example of specific dimensions of the golf ball extractor 18 in this embodiment will be explained with reference to FIG. 3. The diameter D1 of the ball receiving plate 20 is 100 mm, the diameter D2 of the insertion hole 20a is 26 mm, and the thickness t1 is 2 mm. The diameter D2 of the insertion hole 20a is set to be slightly larger than the maximum diameter of the ferrule 16, so that the golf ball extractor 18 can be inserted into the pin 6 to which the ferrule 16 is fixed from the lower end side. ing. The thickness t2 of the fixed piece 26 and the abutting piece 28 of the inclination member 22 is 2 mm, which is the same as the ball receiving plate 20, the width W1 is 46 mm, and the W2 is 20 mm, the radius of curvature R1 of the curved recess 26b is 15 mm, and the lower end of the abutting piece 28 The radius of curvature R2 of the portion 28a is 10 mm. The distance d1 from the center of the insertion hole 20a of the ball receiving plate 20 to the center of the screw insertion hole 20d is 18 mm, the distance d2 from the center of the screw insertion hole 20d to the center of the convex part 32 is 25 mm, and the distance between the centers of the convex parts 32 d3 is 10 mm.

As shown in FIG. 1, when setting the pin 6 in the hole cup 4, the ferrule 16 is inserted into the insertion hole 20a of the ball receiving plate 20 of the golf ball extractor 18, and the pin is press-fitted and fixed to the sounding body 14. 6 is completed. As a result, the golf ball extractor 18 is engaged with the pin 6 so as to be movable in the axial direction thereof. The lower end 28a of the contact piece 28 of the inclination member 22 contacts the upper surface 14b of the sounding body 14 in a point contact state, and the lower surface of the second end region 20c contacts the corner of the sounding body 14, causing the golf ball The take-out tool 18 is placed on the support base 10 with the ball receiving plate 20 tilted. This completes the setting of the golf ball extractor 18. That is, the setting is completed by an extremely simple operation of passing the lower end of the pin 6 through the insertion hole 20a, fixing the pin 6, and then placing it on the support base 10.

Since the pair of abutting pieces 28 of the inclination member 22 and the lower surface of the second end region 20c are in contact with the upper surface 14b of the sounding body 14, a sound transmission path to the sounding body 14 is configured, and the sounding body 14 The pronunciation function is maintained. No matter where the golf ball 24 cupped into the hole cup 4 lands on the ball receiving plate 20, it will eventually come into contact with the second end region 20c of the ball receiving plate 20 and the inner peripheral surface of the cup body 8. It stops in that state.

As shown in FIG. 4, when the club 34 is inserted into the hole cup 4 with the grip 34a facing downward from the state shown in FIG. The pair of abutting pieces 28 serve as fulcrums to rotate the ball receiving plate 20 on the principle of leverage, and the golf ball 24 resting on the second end region 20c on the opposite side is flipped up. The bounced up golf ball 24 flies out of the hole cup 4 and falls onto the nearby putting green 2. The player only needs to look down at the hole cup 4 while standing, locate the pressing point (first end region 20b), and press the club 34 down. That is, since there is no need to bend or stoop at the waist to take out the golf ball 24 from the hole cup 4, no burden is placed on the waist or knees.

As described above, the golf ball extractor 18 of this embodiment has a simple configuration and is easy to set up. Since the entire structure of the golf ball take-out tool 18 exists within the hole cup 4 and is not visible from the outside, the appearance does not deteriorate and the behavior of the golf ball on the putting green 2 is not affected. Further, since there is no need for any member on the pin 6 or the support base 10 side to assist the flipping function, assembly and manufacturing are easy and contribute to cost reduction. Even when it is necessary to remove the pin 6 from the hole cup 4, it is only necessary to remove it from the lower end side of the pin 6 that has been removed from the support base 10, and the operability at the time of removal is good.

The insertion hole 20a of the ball receiving plate 20 is set to a size that allows the above-mentioned flip-up operation, that is, the rotational movement of the ball receiving plate 20 using the pair of contact pieces 28 as a fulcrum, in relation to the outer diameter of the pin 6. ing. When the ball receiving plate 20 rotates, the pair of contact pieces 28 serving as fulcrums support the rotation of the ball receiving plate 20 while sliding on the upper surface 14a of the sounding body 14 so as to approach the center of the ball receiving plate 20. Since the lower end 28a of the abutment piece 28 is semicircular, the ball receiving plate 20 rotates smoothly throughout the entire period from the beginning of the pressing by the club b34 to the end of the pressing. Although the number of contact pieces 28 may be one, rotation of the ball receiving plate 20 is stabilized by providing two contact pieces 28 at a distance from each other as in this embodiment.

Since the golf ball extractor 18 has a structure in which the center of gravity is biased to one side as described above, after extracting the golf ball 24, that is, after pulling up the club 34, the golf ball extractor 18 is tilted on the support base 10 as shown in FIG. It returns to the state where it was placed.

[Second embodiment]
A second embodiment will be described with reference to FIGS. 5 and 6. The same parts or parts that can be considered to be the same as those in the first embodiment are indicated by the same reference numerals, and the explanations regarding the structure and function that have already been given will be omitted as appropriate.

As shown in FIG. 5, the golf ball extractor 36 in this embodiment includes a ball receiving plate 20 and a tilting member 38 fixed to the lower surface of the ball receiving plate 20. As shown in FIG. As shown in FIG. 6, the tilting member 38 has a length extending in the direction of arrow Y, and includes a rectangular fixing piece 40 fixed to the lower surface of the ball receiving plate 20 in the same manner as in the first embodiment. A pair of abutting pieces 42, 42 are provided, each extending from both ends of the fixing piece 40 toward the lower side of the hole cup 4, and each having a lower end 42a having an arcuate shape. The difference from the first embodiment is that the fixed piece 40 does not have a structure corresponding to the curved recess 26b, and each contact piece 42 has a triangular shape, and the radius of curvature R3 of the lower end 42a is different from that of the first embodiment. The radius of curvature is smaller than the radius of curvature R2 of the lower end portion 28a of the contact piece 28, and the convex portion 32 is not provided in the first end region 20b of the ball receiving plate 20.

Compared to the first embodiment, in the first embodiment, the fixed piece 26 can be placed close to the insertion hole 20a due to the presence of the curved recess 26b, so the distance L1 from the force point to the fulcrum shown in FIG. The distance can be made larger than the distance L2. Therefore, there is an advantage that the pressing force (moment) by the club 34 can be made smaller than in the second embodiment. Further, since the operating range of the pressing tool such as the club 34 can be widened, stability during pressing can be obtained. Further, in the case of the first embodiment, since the lower end 28a of the contact piece 28 is semicircular and has a small curvature, the rotational movement when the ball receiving plate 20 flips up is smoother than in the second embodiment. becomes. In addition, in the case of the first embodiment, since the convex portion 32 is provided in the first end region 20b of the ball receiving plate 20 on the side of the tilting member 38, the pressing position may shift due to slipping when the pressing tool is applied. It is possible to prevent this, and the flip-up operation of the golf ball take-out tool 18 can be performed smoothly.

In each of the above embodiments, the tilting member 22 has a structure in which the two contact pieces 28 are integrated (the same applies to the tilting member 38), but as shown in FIG. The members 44 may be individually fixed. In FIG. 7(a), reference numeral 46 indicates a fixing piece, and 46a indicates a screw hole. Further, as shown in FIG. 7(b), the tilting member 48 may have an integral structure having an abutment surface 48c having the same curvature as in the first embodiment at the lower end. In FIG. 7(b), reference numeral 48a indicates a curved recess, and 48b indicates a screw hole.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various changes can be made within the scope of the claims and the technical idea described in the specification and drawings. is possible. For example, in the above embodiment, the dimensions and shapes of each member are specified and illustrated, but the present invention is not limited thereto. Further, the shape of the ball receiving plate 20 is not limited to a circular shape, and may be any shape that can prevent the golf ball 24 from slipping downward and allow it to bounce up.
