DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf ball collecting apparatus installed in a golf driving range, and more particularly to a golf ball collecting apparatus for automatically recovering hit balls without using a human hand or a collecting wheel. About.

[0002]

2. Description of the Related Art A conventional golf ball collecting device is constructed as shown in FIG. As shown in the drawing, the golf ball collecting device 1 is installed on the far side of the golf driving range as seen from the bat, and the slope body 2 laid at the point where the hit ball falls and the slope body 2 of the slope body 2. It mainly comprises a hoisting wire rope 3 attached to an end portion on the back side, a pulley 4 for guiding hoisting of the hoisting wire rope 3, and a winch 5 with a hoisting body for hoisting the hoisting wire rope 3.

The slant member 2 is formed of a synthetic fiber net, and only the front end of the slant member 2 is fixed to the ground when viewed from the bat. On the other hand, the winding wire rope 3 is attached to the rear end of the slant body 2 as described above. Further, a pillar 6 is provided upright on the innermost side of the golf driving range. The pulley 4 is attached at a predetermined height above the column 6. Further, the winch 5 with a winding drum is attached below the column 6. Therefore, the base end of the hoisting wire rope 3 is attached to the winch 5 with a winding drum, and the extended end of the hoisting wire rope 3 is attached to the winch 5 with a winding drum via a pulley 4 provided above the winch 5 with a winding barrel.
It is attached to the rear end of the slant body 2.

The golf balls are collected by the golf ball collecting device 1 as follows. That is, when the front end of the slant body 2 is set as the fixed point b and the rear end thereof is set as the moving point a, when the hoisting wire rope 3 is hoisted by the hoist 5 with the winding drum through the pulley 4. , The moving point a rises forward and follows points aa ₁ , a ₂ and a ₃ . As a result, the inclined body 2 is gradually inclined, golf balls are gathered on the front side along the inclined inclined body 2, and the collected golf balls are collected manually or by using a ball-collecting car. .

[0005]

By the way, in the conventional golf ball collecting apparatus, since the slant body 2 for receiving the golf ball is made of the synthetic fiber net, the slant body 2 is wound by the hoisting wire rope 3. When the golf ball is pulled up, the weight of the golf ball causes the synthetic fiber net to slacken, and the golf ball remains in this slackened portion, which makes it difficult to gather on the front side.

Therefore, in order to collect all the golf balls on the front side of the slope body 2, it is necessary to mount the pulley 4 at a considerably high position of the column 6 and pull up the moving point a to an extremely high position. There was a problem of poor efficiency.

Further, when the sloped body 2 is returned to its original state after the completion of the recovery of the golf balls, the slanted body 2 is lowered by its own weight, so that the sloped body 2 is difficult to return to its original state easily. In particular, when the wind is blowing, the slanted body 2 often catches the wind and does not return to its original state.

Further, since the pulley 4 is attached to the column 6 at a considerably high position, it is very difficult to engage with the ball-proof net and there is a problem that it is not practical.

Since the synthetic fiber net is loosened as described above, the golf ball is likely to concentrate on a specific portion thereof, the portion subjected to the concentrated load is easily stretched or worn, and as a result, the synthetic fiber net is damaged. There was a problem.

In view of the above problems, an object of the present invention is to provide a slant body.
The behavior of the golf ball dropped on top of it is approximated to the natural movement.
And a state, in very efficiently can be recovered golf balls, yet to provide a golf ball collection ball device rich strong and practical.

[0011]

In order to achieve the above object, a golf ball collecting apparatus according to the present invention has a slope body laid at a golf ball drop point on a driving range, and one of the slope bodies is grounded. other Write and lifting while applying a tension to the oblique face piece is fixed, rubber which is adapted to tilt it
In the ruff ball collecting device, the slant body is
The surface of the wire with corrosion resistance is covered with a cushion material.
It is characterized by being formed by polymerizing a decorative material.

In the above structure, preferably, the slanted body is hoisted by a balance winch.

[0013]

[0014]

According to the above construction, one of the slanted bodies laid at the falling point of the golf ball on the driving range is fixed to the ground, while the other is slanted. Therefore, although the slanted body is inclined, the lifting is performed so that tension is applied to the slanted body, so that the slanted body does not loosen. As a result, since there is no golf ball remaining in the slack portion, all the golf balls that have fallen onto this slant are collected on the fixed side. Since the sloping body is not loosened in this manner, it is not necessary to lift the sloping body high, and the golf ball is efficiently collected. Also, tensile strength
And the surface of the wire with corrosion resistance through the cushion material
The slanted body formed by polymerizing the decorative material is used.
It's durable and practical because it is hard to break due to its tensile strength and corrosion resistance.
Of golf balls that fall on this slope.
Motion is reproduced in a state similar to natural motion.

When the slant body is suspended by a balance winch, the slant body can be easily and appropriately tensioned by the forward and reverse rotation of the winch motor, and the looseness can be easily removed. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a golf ball collection device according to the present invention will be described in detail below with reference to the accompanying drawings.

The golf ball collecting apparatus of this embodiment is shown in FIG.
And as shown in FIG. As shown in the drawing, a slanted body 22 that constitutes a golf ball collecting device 21 is laid at the falling point of the flying ball on the far side when viewed from the bat at the driving range. The front end of the slanted body 22 as viewed from the bat is fixed to the ground. On the other hand, the winding wire rope 23
Is inserted. The hoisting wire rope 23 is formed in an endless shape, and passes through the first pulley 24, the balance winch 25, and the second pulley 26 in this order from the end portion on the inner side of the slant body 22, and again the slant body. It is inserted through the end portion on the back side of 22.

A pillar 27 is provided at the farthest side of the driving range.
Is provided upright, and the pillar 27 has the above-mentioned first
Pulley 24, balance winch 25 and second pulley 26
Is installed. That is, the first pulley 24 is provided at a predetermined height position of the support column 27, the balance winch 25 is provided below the first pulley 24, and the second pulley 26 is provided below the balance winch 25. As shown in FIG.
Guide pulleys 28a and 28b for guiding the movement of the hoisting wire rope 23 are provided between the first pulley 24 and the balance winch 25 and between the balance winch 25 and the second pulley 26, respectively. . The balance winch 25 is attached to the reversible capstan 25a for winding the hoisting wire rope 23, the winch motor 25b for driving the reversible capstan 25a, and the hoisting wire rope 23. An upper balancer 25c located above the capstan 25a and a lower balancer 2 located below the reversible capstan 25a.
5d.

Further, FIG. 3 is a partially cutaway plan view showing the structure of the slant body 22, and FIG. 4 is a side sectional view thereof. The slope 22 is placed directly on the ground, and moisture from the ground surface enters the slope 22. Therefore, the slope 22 must be formed of a material resistant to corrosion. In addition, for example, the length must be 30 m and the width must be 10 m, and it must be formed of a material that can withstand the tension for lifting one point. In addition, when the golf ball falls on the slope 22, it is necessary to create a state similar to the behavior of falling on natural grass.

Specifically, the slanted body 22 is constructed as follows. The skeleton portion of the slant body 22 is, for example,
It is formed by arranging AS ropes 22a having a diameter of 6.0 mm vertically and horizontally in a grid pattern. This AS rope 22a
Is a tension body for receiving the tension applied to the slant body 22, which is arranged at intervals of about 1 m in the vertical direction and about 5 meters in the horizontal direction.
They are arranged at intervals of 10 m. The intersections of these vertical and horizontal AS ropes 22a are bound by AS lines. An AS lifting wire 22c is attached to an end portion on the back side of the lattice-shaped AS rope 22a via a wire clip 22b. The AS hoisting wire 22c is formed by twisting an AS wire, and the hoisting wire rope 23 is inserted through the AS hoisting wire 22c at intervals of the width of 10 m. That is, the AS lifting wire 22c is the winding wire rope 2 described above.
They are arranged in an arc shape between the three. By thus arranging the AS hoisting wires 22c in a bow shape, it is possible to uniformly apply strong tension by the hoisting wire ropes 23 to the slant body 22. A tension wire net 22d is stretched on the lattice-shaped AS ropes 22a.
The tension wire netting 22d is bound to the AS rope 22a by an AS wire. Furthermore, a cushion material 22e made of, for example, a chemically synthetic fiber or an organic foam is polymerized and fixed on the tension wire net 22d so as to cover the entire surface thereof. A surface decoration material 22f is further polymerized and fixed on the cushion material 22e. In the present embodiment, the surface decoration material 22f is made of artificial grass, but it is not limited to this and may be made of, for example, a carpet material, a woven cloth, a soft sheet or the like.

Next, the operation of the above embodiment will be described.

As shown in FIGS. 1 and 2, the end of the slant body 22 on the front side when viewed from the bat is designated as the fixed point D, and the end on the rear side thereof is designated as the moving point A. The slanted body 22 between the moving point A and the fixed point D is pulled by the hoisting wire rope 23 forming the triangles A, B, and C while A-
Lifted following the A _1, A _2, A ₃ points sequentially. Unlike the slope body 2 of the conventional golf ball collection device 1 shown in FIG. 7, the golf ball collection device 21 of the present embodiment cannot have a large slack in the slope body 22. In addition, the golf ball collection device 21 of this embodiment is too high and the slope 22
The golf ball G can be collected without pulling up, and the golf ball can be collected by pulling up at a position considerably lower than the slant body 2 of the conventional golf ball collecting device 1.

Specifically, although the moving point is at the point A in the initial state of the slanting body 22, when the hoisting wire rope 23 moves in the direction of the arrow by the forward rotation of the winch motor 25b of the balance winch 25, Point A is A ₁ , A ₂ ,
Ascends to A ₃ . At this time, the slanted body 22 is forcibly pulled up while the tension is still applied. By the way, (BA) + (AC) and (BA ₁ ) + (A ₁ C) or (B) in the winding wire rope 23.
The length of A ₂ ) + (A ₂ C) is not completely constant, and the upper balancer 25c and the lower balancer 25d are automatically adjusted by the changing length of the hoisting wire rope 23. Is.

Further, the moving point for completing the collection of the golf ball G is not necessarily the point of A ₃ , but the point of around A ₂ .
When the golf ball G has been completely collected, the winch motor 25b is reversed so that the slanted body 22 can be pulled down to the point A. Also in this case, since the slanted body 22 is forcibly pulled down while receiving the tension, it can be completely returned to the original position. If necessary, slahedron 2
When the moving point of 2 returns to point A, it is possible to lay it by further applying tension.

Further, when the slanted body 22 is slack, if the winch motor 25b is further reversed, the slack can be completely removed by applying tension to the winch motor 25b. This is effective even when the slant body 22 is placed on the ground.

Incidentally, if the ball discharge groove 29 is appropriately formed in the vicinity of the fixed end of the slant body 22, the golf balls G collected along the slant body 22 can be easily collected. Is.

As described above, in the golf ball collection device 21 of the present embodiment, it is not necessary to make a fixed slant body for collecting the golf ball G, and there is no need to make a foundation as a foundation therefor. . Since the slant member 22 of the golf ball collection device 21 of the present embodiment is formed by using the AS twisted wire or the wire mesh of the AS wire, the cushion material, and the artificial turf, it has tensile strength and corrosion resistance. It is durable and practical. In addition, the golf ball G dropped on the slope 22
The behavior of is reproduced in a state similar to natural movement.

FIGS. 5 and 6 show a concrete example in which the golf ball collecting device 21 is actually applied to a golf driving range. FIG. 5 is its plan view and FIG. 6 is its side view. Is. The slanted body 22 in FIG. 5 shows only the frame of the AS rope 22a. As shown in the figure, assuming a general driving range with a total length of about 200 m and a width of about 50 m at the back, about 70 at the back.
The golf ball collection device 21 of the present embodiment is installed in the m portion. The front side is the fixed side in the 30m part in the back,
One slant body 32a is installed so that the inner side is the moving side,
At the 40m portion in front of it, the two slanted bodies 32b, 3 are arranged so that the center is the fixed side and the side is the moving side so as to face each other.
2c is installed.

An existing concrete pole is used for the pillar 27. In addition, the above balance winch 25
Are attached to the rear of these columns 27 facing the inside of the field, but may be attached to the side. Specifically, the balance winch 25 is attached to the six columns 27 in the back 30 m, and the balance winch 25 is attached to the left and right five columns 27 in the front 40 m. The balance winch 25 attached to the columns 27a, 27b, 27c, and 27d located at the ends of the slopes 32a, 32b, and 32c among the columns 27 has the slopes 32a and 32c.
Since the ends of b and 32c are pulled up, it is essential to install the balance winch 25 so that the AS lifting wire 22c is pulled obliquely outward by the hoisting wire rope 23 and pulled up.

Further, the ball discharge groove 29 is formed in the slant body 3
It is formed in a T shape from the arrangement of the fixed sides of 2a, 32b, 32c. In the ball discharge groove 29, the slant body 3
An anchor 33 for fixing the fixed side of 2a, 32b, 32c is installed. In this case, the ball discharge groove 29
It may be formed as an anchor.

Further, as shown in FIG. 6, 34 is a ball-proof net in a golf driving range, and this ball-proof net 34 is attached to the end of each slant body 32a, 32b, 32c on the moving side. The lower parts of the parts 32a, 32b, 32c are driven as they are moved up and down.

In FIG. 5, if the target green is formed on the slant member 22 by the surface decoration material 22f, the golf ball G on the green can be collected at the same time. Then, in order to make the falling point of the golf ball G clearly visible from the bats side, the inclined body 32a in the inner portion of 30 m can be held at a certain inclination.

When actually applied to a golf driving range, the golf ball G can be efficiently collected by installing the above-mentioned golf ball collecting device 21 and forming the ball discharge groove 29 even if the ground is not leveled. be able to. When the golf ball collecting device 21 is installed, since the entire slope body 22 is configured as a so-called carry-in structure, the slope body 22 can be installed on a golf driving range by section. Therefore, it is not necessary to take a full holiday to renovate an existing practice field, and temporary partition nets and the like can be appropriately installed, and can be installed while partially operating, which is highly versatile.
