[Problem that the idea aims to solve]

However, as mentioned above, the pole, which was tilted toward the green, can be rotated back to the upright position. When a long pole is rotated from a horizontal position to an upright position, it takes a lot of effort. A large turning force is required, but the load added to the connecting part corresponds to the length of the pole. Because of this, the connection side circumferential surface of the pole is attached to the upper end corner of the hollow shaft like in conventional equipment. If you return the rotation while making contact with the pole, there will be a large contact resistance at the contact area between the hollow shaft and the pole. Resistance may occur and the connecting part of the pole may break or curve when returning to rotation. Therefore, there is a limit to the length of the pole that can be rotated back using the conventional device. For this reason , if the area of the green is wider than the rotation range of the pole, the outer periphery of the green may I was unable to remove the golf ball that was on the ground, and the golf ball that I hit Not only is it difficult to locate the golf ball, but it also interferes with the golf ball's roll. This poses a problem in that golf practice such as approach shots cannot be performed.

0004 This idea was developed in view of the above problems, and when the pole returns to rotation, the pole and slider By reducing the contact resistance with the pole by rotating the rolling elements, the pole can be returned to an upright position. It is easy to let the golf ball return to its original position, and it also allows you to hit the golf ball on the green all at once. To provide a golf ball removing device that can easily remove golf balls.

[0005]

[Means to solve the problem]

This idea uses a connection part between the rotating shaft and the pole to rotate the pole into an upright position. A slider that slides up and down between a raised position where it is fixed and a lowered position where it is released from the rotational fixation mentioned above. A point is provided to move the slider up and down in the direction of rotating the above-mentioned pole back to the upright position. A ball undulating means is provided at the upper end of the slider, and the slider is tilted toward the green side. The rolling element that guides the raising of the pole is rotatable, facing the circumferential surface of the lower end of the pole. The present invention is characterized in that it is a golf ball ejecting device that can hold golf balls with ease.

[0006]

[Effect]

The golf ball removing device of this invention drives the pole raising and lowering means to move the slider. After descending to the lowering position and tilting the pole in an upright position onto the green, The pole tilted toward the green is rotated horizontally to remove the golf ball. do.

[0007] Also, when rotating the pole back to the standing position, the pole hoisting means is driven. Raise the slider from the lowered position to the raised position, and at the same time The held rolling element rises while contacting the lower end side circumference of the pole, and slides between the pole and the slide. The contact resistance with the pole is reduced by the rotation of the rolling elements, and the connection between the pole and the rotating shaft is Move the slider to rotate and fix the pole in the standing position.

[0008]

[Effect of the idea]

As a result of the above, according to this invention, the work of removing golf balls can be done all at once and reliably. The pole can be easily rotated to an upright position after the golf ball has been removed. When returning, the contact resistance between the pole and slider is reduced by the rotation of the rolling elements. Compared to conventional equipment, the turning force required to return the pole to the standing position is smaller. This makes it easy to return the pole to rotation, and also ensures that the pole does not break or curve. can be prevented.

[0009] Therefore, it is not possible to reliably prevent the pole from breaking or bending, unlike conventional devices. Wear. And this effect changes whether the pole is long or telescopic. Therefore, by widening the rotation range of the pole, you can move the golf ball on the green. It can be eliminated all at once, and you can check the position and roll of the golf ball you hit. It is ideal for practicing golf such as approach shots without being obstructed, and it also allows you to use the golf ball. The removal work can be done in a short time, saving labor and improving efficiency. Ru.

A slider 8 is attached to the outer peripheral surface of the connection part with the rotating shaft 7 so as to be able to slide up and down. Lap the upper end opening facing the lower end circumferential surface of the pole 3 that is tilted toward the green 2. The opening 8a on the slider 8 is opened in the shape of a cylindrical shape, and the upper end side opening 8a of the slider 8 is turned upward to make the diameter larger. It is formed into a smooth guide surface. The upper end side opening of the slider 8 8a, a large number of rolling elements 9 formed in a spherical shape around the pole 3 are mounted outside the pole 3. These rolling elements 9 are arranged in the circumferential direction closely at intervals narrower than the diameter dimension, and each of these rolling elements 9... is rotatably held by a holding frame 9a fixed to the upper opening 8a of the slider 8. ing.

[0013] The slider 8 further includes link rods 10 on both sides of the lower end of the slider 8. Install 10. A guide hole 10a is provided in the intermediate portion of each of these link rods 10, 10. Guide pins are provided in the formed guide holes 10a to protrude from both sides of the lower end of the slider 8. 11, 11 and attached to both sides of the lower end of the slider 8. 10, one side of the lower side of 10 and the box 12 buried in the center of green 2. and the other side of the upper side of each of these link rods 10, 10.

The slider 8 is supported in a vertical position and moved up and down to a lowered position where the position is released.

[0014] The above-mentioned pole rotation mechanism 5 has a bottom end portion of a rotating shaft 7 formed in a hollow cross-sectional shape. A bearing 14 is inserted into the center of the box 12 and fixed to the center of the box 12. , 14 rotatably supports the rotating shaft 7, and is arranged inside the box 12. It is fixed to the sprocket 16 of the rotating motor 15 with a reducer and the lower end of the rotating shaft 7. The drive chain 18 is stretched around the sprocket 17 with a torque limiter, and the rotation The driving force of the motor 15 drives the sprockets 16, 17 and the drive chain 18. The rotating shaft 7 is rotated through the shaft, and the pole 3 connected to the rotating shaft 7 is tilted toward the green 2 side. Rotates horizontally while in the folded position.

[0015] In addition, a wire winding machine 19 is disposed inside the box 12, and the wire winding machine 1 The wire 22 is wound by a predetermined amount on the winding drum 20 constituting the winding drum 9. The gear 22 is inserted into the rotating shaft 7 via a pulley 23 bearing at the center of the bottom of the box 12. The end of the wire 22 is fixed to the lower end of the hollow pole 3a that constitutes the pole 3. ing. In other words, the winding driver is rotated by forward and reverse rotation of the winding motor 21 with a speed reducer. By winding or unwinding the wire 22 onto the pole 3, The extension and contraction lengths of the empty poles 3a, 3b, and 3c are variably adjusted.

[0016] The illustrated embodiment is constructed as described above, and the golf ball removing device 1 will be described below. The operation of removing golf ball A will be explained below. First, when removing golf ball A on green 2, as shown by the imaginary line in Figure 1, Then, the lifting cylinder 13 of the pole hoisting mechanism 4 is lowered to rotate with the pole 3. The slider 8 is lowered below the connection part with the shaft 7, and the connection between the pole 3 and the rotating shaft 7 is Release the rotation fixation and tilt the pole 3 installed in the center of the green 2 to either side. After it is knocked down, as shown in FIG. 4, the rotation motor 15 of the pole rotation mechanism 5 is driven. , the pole 3 tilted toward the green 2 is horizontally rotated in the direction of the arrow. And the wire The winding motor 21 of the winding machine 19 is reversely driven in the rewinding direction, and the winding motor 21 of the winding machine 19 is The wire 22 wound around the coil 20 is gradually unwound, and the centrifugal force generated during rotation causes the wire 22 to be Rotate horizontally while extending 3 in the length direction, and all the golf balls on green 2. Eliminate ball A...

[0017] Next, when rotating the pole 3 that has been tilted toward the green 2 side to the upright position, The rotation motor 15 of the wire rotation mechanism 5 is stopped, and then the wire winding machine 19 starts winding. The winding motor 21 is driven forward in the winding direction and fixed to the hollow pole 3a of the pole 3. The wire 22 that has been After reducing the pole 3 to its original size, as shown in Figure 2, the pole hoisting mechanism 4 is The cylinder 13 is moved upwardly, and the slider 8 is vertically moved along the circumferential surface of the lower end of the pole 3. Each rolling element held in the upper end opening 8a of the slider 8 9... rises while contacting the lower end side circumferential surface of the pole 3, and the pole 3 and the slider 8 The contact resistance of is reduced by the rotation of each rolling element 9..., and the pole 3 returns to rotation in the upright direction. Then, the connection part between the pole 3 and the rotating shaft 7 is fixed in a vertical position by the slider 8. By doing so, the raising operation of the pole 3 is completed.

[0018] In this way, the telescoping pole 3 tilted toward the green 2 side can be extended in the length direction. Since the golf ball A is rotated horizontally from the pole 3, all golf balls A within the rotation range of the same pole 3 are rotated horizontally. You can eliminate the golf ball A at once, and check the position and roll of the golf ball A that you hit. It is ideal for practicing golf such as approach shots without being obstructed, and it also allows you to use the golf ball. Elimination work of Rule A can be done in a short time, saving labor and improving efficiency. can.

[0019] Moreover, after shrinking the pole 3 that has been extended by centrifugal force to its original size, the slider 8 to return the pole 3 to the standing position, and after removing the golf ball. When returning the pole 3 to the upright position, the contact resistance between the pole 3 and the slider 8 This is reduced by the rotation of the rolling elements 9, so the pole 3 can be placed in an upright position compared to conventional devices. Only a small rotational force is needed to return the rotation, and the rotation of the pole 3 can be easily returned. At the same time, bending, bending, etc. of the pole 3 can be reliably prevented.

[0020] In FIG. 5, two guide rollers 24, 24 are placed relative to the upper end side opening 8a of the slider 8. This is another embodiment in which the shafts are pivoted facing each other. In other words, the slider 8 is centered around the pole 3. Guide rollers 24, 24 are pivotally supported opposite each other in the upper end side opening 8a, and the pole 3 is Two other photoelectric sensors, etc., are installed at two opposite locations on the center slider 8. sensors 25 and 26 are arranged. Each of these sensors 25, 26 is connected to a tilted port. As described later, the tilted pole 3 rotates horizontally to detect the sensor 2. After either one of 5 or 26 is detected, it continues to rotate horizontally, and after a predetermined period of time has elapsed. The pole 3 is rotated so that it is positioned above the two guide rollers 24, 24. It is for stopping. In other words, the above-mentioned positions for raising and lowering rotation of the pole 3 are different from each other. The position of the pole 3 on the guide roller 24 is determined by the arrangement position of the sensors 25 and 26. After the rotation of the pole 3 is stopped, the pole 3 is rotated back to the upright position after the golf ball has been removed. The contact resistance between the pole 3 and the slider 8 is reduced by the rotation of the guide roller 24. As a result, the rotation of the pole 3 can be easily restored as in the previous embodiment.

[0021] The rolling element of this invention corresponds to the rolling element 9 and guide roller 24 of the embodiment, Similarly below, The pole hoisting means includes a pole hoisting mechanism 4, a link rod 10, and a lifting cylinder 1. Although it corresponds to 3, This invention is not limited to the configuration of the above-described embodiment.

[0022] For example, the guide roller 24 may be installed at four or more locations in the upper end side opening 8a of the slider 8. You may set up a location.
