Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a golf ball removing device for removing a ball on a green of a driving range.

[0002]

[Prior art]

 A golf ball excluding device is provided with Japanese Patent Application No. 59- The applicant has already proposed it as 260198.

[0003]

[Problems to be solved by the device]

 However, in the conventional golf ball excluding device as described above, the support rod remains protruding even when the pole is upright, so the golf ball hit by the customer at the driving range hits the support rod and the bat May bounce off and be dangerous. Therefore, the object of the present invention is to obtain a golf ball excluding device in which the hit ball does not hit the support rod.

[0004]

[Means for Solving the Problems]

 Therefore, the support rods can be moved up and down, and when the poles are in the upright state, the support rods are interlocked to be lowered and stored.

[0005]

[Action]

 When the pole is lying sideways to eliminate the ball on the green, the support rod rises, and the support rod receives the reaction force due to the rotation of the pole. When the pole is upright, the support rod is interlocked and stored downward, so that the golf ball hit by the customer does not hit the support rod.

Embodiments Embodiments of the present invention will be described below. FIG. 1 is a perspective view of a green 2 incorporating a golf ball excluding device 1 according to the present invention. A rotating body 3 is provided in the golf ball excluding device 1, and a pole 4 is erected on the rotating body 3. A flag 5 is attached to the upper end of the pole 4. As shown in the figure, the pole 4 can be switched between the upright state indicated by the solid line 4a and the sideways state indicated by the alternate long and short dash line 4b, and the rotating body 3 is rotationally driven in the sideways state of the pole 4. As a result, the golf ball 6 on the green 2 is excluded to the outside. The rotating body 3 is provided with a support rod 7 for receiving the reaction force of the pole 4 when the pole 4 rotates in such a state that the pole 4 is laid sideways. Further, inside the pole 4, there is a telescopic rod 8 which is designed so as to project from the inside of the pole 4 by the centrifugal force when it is rotationally driven in a sideways state.

FIGS. 2 and 3 are enlarged views of the golf ball excluding device 1, FIG. 2 shows the pole 4 in an upright position, and FIG. 3 shows the pole 4 in a lateral fall. A rotating body 3 is rotatably provided in the center of the excluding device body 10 via a bearing 11, and a gear 12 formed around the rotating body 3 and a pinion 14 of a motor 13 fixed to the excluding device body 10 mesh with each other. Due to the matching, the rotating body 3 is rotationally driven by the operation of the motor 13. Two through holes 15 and 16 are bored in the rotating body 3, the base of the pole 4 is inserted into the through hole 15, and the support rod 7 is inserted into the through hole 16. A flange 17 is formed at the lower end of the support rod 7, and the flange 17 is pushed down by the extension force of the spring 18 mounted around the support rod 7, so that the support rod 7 is always inserted into the through hole 16. It is urged to pull inside. A protrusion 19 is formed at the lower end of the through hole 16 to engage with the flange 17 and regulate the lowering limit of the support rod 7.

As shown in FIG. 4, a curved guide groove 20 is formed in the upper portion of the through hole 15 so as to gradually become deeper toward the through hole 15. The rotor 3 is seen from above as shown in FIG. 5, and the through hole 16 of the support rod 7 is located right next to the guide groove 20. As shown in FIG. 2, a connecting rod 21 is flexibly pin-joined to the base of the pole 4, and the lower end of the connecting rod 21 is fixed to a rotating block 22 arranged below the rotating body 3. ing. A protrusion 23 is provided upright on the rotary block 22 so as to be positioned just below the through hole 16 of the support rod 7. A trunnion 24 that rotatably supports the rotating block 22 is attached to the lower side of the rotating block 22, and the rotating block 22 and the trunnion 24 are provided along a guide rod 25 provided at substantially the center of the rotating body 3. It can be raised and lowered. The trunnion 24 is connected to the tip of a swingable lever 27 pivotally supported by the expulsion device body 10, and the lever 27 is swung by the expansion and contraction operation of a cylinder 28 mounted at approximately the center of the lever 27. When moved, the trunnion 24 and the rotation block 22 are configured to move up and down along the guide rod 25. Then, when the rotary block 22 rises, the pole 4 and the connecting rod 21 gradually bend while being regulated by the guide groove 20 as shown in FIG. 6, and the lateral side of the pole 4 as shown in FIG. In addition to being in the state of falling, the protrusion 23 provided upright on the rotation block 22 is fitted into the through hole 16 of the support rod 7 from below to push up the support rod 7 against the force of the spring 18. As a result, the upper end of the support rod 7 projects above the rotating body 3.

Now, in the golf ball excluding device 1 as described above, when the cylinder 28 is extended and the rotary block 22 is descended as shown in FIG. 2, the pole joined to the connecting rod 21 by the pin is joined. The base of 4 is pulled into the through hole 15, and the pole 4 is in an upright state. Further, the protrusion 23 provided upright on the rotation block 22 is also lowered, and the support rod 7 is pushed down by the force of the spring 18 and is accommodated in the through hole 16. Then, when the pole 4 is in the upright state in this manner, the customer hits the golf ball with the pole 4 facing, but the support rod 7 is retracted, so the golf ball 6 hit by the customer is the support rod 7. There is no worry to hit.

When the golf balls 6 accumulated on the green 2 are to be removed, first, the cylinder 28 is operated in a shortened manner and the rotary block 22 is raised. As a result, as described with reference to FIG. 6, the pole 4 and the connecting rod 21 are gradually bent while being regulated by the guide groove 20, resulting in the state in which the pole 4 falls sideways as shown in FIG. The raised portion 23 is fitted into the through hole 16 of the support rod 7 from below and pushes up the support rod 7 against the force of the spring 18, so that the upper end of the support rod 7 projects above the rotating body 3. Here, as shown in FIG. 5, the through hole 16 is located immediately beside the guide groove 20, so that the support rod 7 protruding above the rotating body 3 is guided by the guide groove 20 as shown in FIG. The pole 4 which is regulated by the above and is in the state of falling sideways is projected to the side, and the side of the pole 4 is pressed by the support rod 7. In this way, when the pole 4 is laid down sideways and the side of the pole 4 is pressed by the support rod 7, the motor 13 is operated to rotationally drive the rotating body 3 to rotate the pole 4 on the green 2. As a result, the telescopic rod 8 built inside the pole 4 pops out by the centrifugal force and extends as shown by the alternate long and short dash line in FIG. 1 to eject the golf ball 6 on the green 2 to the outside. Further, the reaction force due to the rotation of the pole 4 is received by the support rod 7.

Then, when the elimination of the golf ball 6 is completed, the cylinder 28 is extended again and the rotary block 22 is lowered as shown in FIG. As a result, the base of the pole 4 is pulled into the through hole 15, and the pole 4 is in the upright state. Further, when the protrusion 23 is lowered, the support rod 7 is pushed down by the force of the spring 18 and is housed in the through hole 16. Thus, the customer starts hitting the golf ball 6 again, but since the support rod 7 is retracted, there is no fear of hitting it.

[Effect of device]

 According to the golf ball excluding device of the present invention, when the pole is upright, the support rod is interlocked and retracted, so there is no concern that the golf ball hit by the customer hits the support rod. It is safe with no bounce problems. Also, when the pole is laid sideways to eliminate the ball on the green, the support rod moves up and the reaction force due to the rotation of the pole can be received by the support rod.
