Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf practice mat and, more particularly, to a golf practice mat in which a ball mounting table for placing a golf ball is laid on a ball mounting table which can be tilted.

[0002]

2. Description of the Related Art A golf driving range for practicing golf shots is constructed in the suburbs of the city by surrounding the surroundings with a net or the like, and many golf fans go out to practice on holidays.
I practice shots. In a golf driving range of this kind, generally, an artificial turf shot mat is laid on a normal floor or the ground, and a practicer stands on the golf club and swings a golf club to practice a shot.

[0003]

The practice of a shot at such a golf driving range is just a practice, and it is important to be able to hit an accurate shot as desired when standing on a golf course that is a real golf course. . However, there is a big difference between an actual golf course and a driving range. One of the differences is that the shot practice position of the driving range, that is, the place where the trainee stands, is always horizontal. Even so, there are grounds inclined in various directions, and even on rough or bunkers or inclined surfaces, shots must be taken on inclined surfaces inclined in various directions.

[0004] For this reason, there is a problem that even if the player practices a shot at a golf driving range, he / she cannot hit an accurate shot when he goes to an actual golf course and plays golf. There has been a demand for a golf practice table that can effectively practice shots in various postures according to the terrain of the course.

In view of the above, conventionally, various golf practice tables provided with a tilt table that can be tilted in an arbitrary direction have been proposed. When performing a shot on a golf practice table having a tilt table of this type, a golf practice mat is laid on the tilt table, a ball is placed on the mat, and the shot is practiced. However, since the inclination angle can be adjusted to an arbitrary angle, when the inclination is steep, the ball rolls on the mat, and there has been a problem that shot training on the inclined surface cannot be performed stably.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem. Even if the ball is laid on an inclined ball mounting table, the ball does not roll and the golf shot practice is performed stably and favorably. It is an object of the present invention to provide a golf practice mat that can be used.

[0007]

In order to achieve the above object, a golf practice mat according to the present invention is a golf practice mat laid on a tiltable ball mounting table, and is formed in a flat plate shape. On the mat substrate, a large number of brush bristle bundles are planted at regular intervals, and each brush bristle bundle has a standard hair having a standard length, and a proportion of long bristle longer than the standard bristle is smaller than the standard bristle. It is characterized by being mixed and planted.

[0008]

This golf practice mat is used by laying it on a tiltable ball mounting table, placing a ball on the golf practice mat and swinging the golf club to practice a shot. At this time, the mat of the ball mounting table is inclined, and the ball may roll.However, the long hair protruding upward in a rough state from the standard hair of the mat holds the ball, so the ball is rolled. Instead, it is possible to practice the shot while holding it stably at the placed position.

When practicing iron shots such as a sand wedge and a pitching wedge, the lower part of the club head enters a brush bristle bundle below the ball and is swung out. Unlike conventional artificial turf made of polymer elastic, the frictional resistance is very small, and a small number of long hairs hold the circumference of the ball, so it is possible to swing the club head relatively easily. The wear of the brush bristle bundle is very small, and the life of the golf practice mat can be extended.

[0010] Further, as set forth in claim 2, the brush bristle bundle comprises:
The intermediate portion of the bundled brush bristles is bent, inserted into a flocking hole pre-drilled on the mat substrate, and fixed to the mat substrate with a U-shaped pin and an adhesive. Can be planted satisfactorily by preventing falling off.

Further, each brush bristle bundle is provided with a synthetic resin having an outer diameter of 0.4 mm to 0.7 mm in a flocked hole formed at predetermined pitch intervals vertically and horizontally on a flat surface of a mat substrate. A set of 20 to 25 bristles made of brush is inserted and inserted into the bent middle part, and the standard length of the bristles of the bristles is 40.
mm to 60 mm, and the length of long hair is 20 times longer than that of standard hair.
With a configuration formed by 30% to 30% longer, the ball can be stably held on the mat, the mat is not worn, and the shot practice can be performed satisfactorily.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a plan view of a golf practice mat, and FIG. 2 shows a side view thereof. In the golf practice mat, basically, a large number of brush bristle bundles 2 are planted at regular intervals on a mat substrate 1 formed in a flat shape, and each brush bristle bundle 2 has a standard length. Standard hair 2 with
The long hair 2b longer than the standard hair 2a is included in the standard hair 2a.
It is constructed by mixing and planting in a smaller proportion.

That is, the mat substrate 1 is formed of a relatively hard synthetic resin such as vinyl chloride into a plate having a thickness of about 15 mm, and has a large number of flocked holes on its upper surface as shown in FIGS. 1a are arranged and formed in a staggered manner at intervals of a pitch P (about 5 mm). The diameter of the flocking holes 1a is about 5 mm and the depth is about 12-13 mm.

A brush bristle bundle 2 is planted in these flocking holes 1a. As shown in FIG. 3, the brush bristle bundle 2 has a brush bristle bundle 2 with a U-shaped pin 3 in an intermediate portion of the brush bristle bundle 2 in a state in which an adhesive is applied to the inner surface of a large number of flocking holes 1 a. The U-shaped pin 3 is pushed into the mat substrate 1 while being sandwiched, and the intermediate portion of the folded brush bristle bundle 2 is press-fitted and adhered to the flocking hole 1a for planting. In other words, this golf practice mat is constructed by implanting brush bristle bundles 2 used in a general cleaning brush on the mat substrate 1 at regular intervals.

The brush bristle bundle 2 has a thickness (outer diameter) of 0.1 mm.
It is made by mixing and bundling standard bristles 2a of 4 mm to 0.7 mm (preferably 0.5 mm to 0.6 mm) and long bristles 2b of the same thickness and length. 25 (preferably 22 to 23) long hairs 2b are about 10% to 20% of standard hairs 2a, ie, about 2 to 4 hairs are standard hairs 2a.
Is mixed and bundled. The brush bristle bundle 2 is formed by bending the standard bristle 2a and the long bristle 2b from the middle part into two and planting them.
The number is from 4 to 46, and the number of long hairs 2b is from 4 to 8. Further, since the length h ₀ in the implanted state of the standard bristles 2a is about 50 mm, the length h ₁ of Nagashakuke 2b is about 60mm~ about 65 mm, a length of Nagashakuke 2b are standard hair About 20% from 2a
It will be formed 30% longer.

As shown in FIGS. 1 to 3, flocked holes 1a having an inner diameter of 5 mm are arranged in a zigzag pattern on a mat substrate 1 at a pitch P of 5 mm, and a brush bristle bundle 2 is planted in the flocked holes 1a. However, since these brush bristle bundles 2 are spread so that their tips have an area of about twice in plan view, the upper surface of the golf practice mat is almost uniformly covered with brush bristle, In each brush bristle bundle 2, 10% to 20% of the long bristles 2b are mixed in the standard bristles 2a, so that the tips of the long bristles 2b protrude 10 mm to 15 mm above the standard bristles 2a. Will appear.

The standard bristle 2a and the long bristle 2b of the brush bristle bundle 2
Has a sufficient stiffness and high durability because it uses vinyl chloride or nylon wire (outer diameter of about 0.5 to 0.6 mm) (used for general cleaning deck brushes, etc.). Can be made.

As shown in FIG. 5, the golf practice mat constructed as described above is used by being mounted on a ball mounting table 17 provided on the side of the tilt table 2 so that the tilt can be adjusted.

The tilting table 12 is disposed on the base 11 so as to be tiltable. The base 11 is formed in a substantially square plate shape using an angle member, a tube member having a rectangular cross section, and the like, and the support shaft 1 is provided at the center.
The tilting table 12 is connected to the support shaft 14 via a pillow block at the tip, and the tilting table 12 is supported on the base 11 in a tiltable manner. Further, at four places on the base 11, that is, the center of the base 1 when viewed in a plan view is set as the center position of the XY coordinates, and at the equidistant positions on the X axis and Y axis,
Two pairs of hydraulic cylinders 15, 16 are mounted with their piston rods facing upward, and one pair of hydraulic cylinders 1
Reference numerals 5 and 16 are installed on the X axis, and a pair of hydraulic cylinders (not shown) are installed on the Y axis.

Each of the hydraulic cylinders 15, 16 is pivotally supported by a horizontal axis along the X-axis and Y-axis so that the distal ends of the piston rods 15a, 16a of the hydraulic cylinders 15, 16 are orthogonal to the pivots. Are connected to the inside of the tilting table 12 by a horizontal shaft.

The tilting table 12 is formed in a substantially square plate shape using an angle member, a tube member having a rectangular cross section, or the like, and a plate member 19 is mounted thereon, and a rubber or polymer elastic material is placed on the plate member 19. Mats are laid. Such a tilting table 12 can be tilted in any direction on the base 1 by being supported by the tip of the support shaft 4 erected at the lower center, and tilted by the operation of the fluid pressure cylinders 15 and 16. I do.

The ball mounting table 17 is formed in a rectangular plate shape, is connected to an end of the tilt table 12 via a hinge 18, and can be tilted up and down. In order to automatically tilt the ball mounting table 17, a pair of hydraulic cylinders 13 are pivotally supported inside the tilting table 12 via a horizontal connecting shaft, and the tip of the piston rod 13 a is connected to the ball mounting table 17. Is connected to the lower side through a shaft. When the piston rod 13a of the fluid pressure cylinder 13 is pushed out, the ball mounting table 1
Numeral 7 tilts so that its free end is raised upward, and when the piston rod 13a is pulled back, the ball mounting table 1
7 tilts downward.

A golf practice mat having the above-described structure is laid on the ball mounting table 17. As shown in FIG. 6, the golf practice mat has a structure in which a large number of brush bristle bundles 2 are planted on a mat substrate 1. The brush bristle is used when a golf ball B is placed thereon. It is planted densely enough to hold the ball B on the standard bristles 2a without sinking so much, and has sufficient elasticity.
When the ball mounting table 17 on which the mat is laid is inclined as shown in FIG. 6, the ball B easily rolls in the inclination direction. Since the long bristles 2b that are 20% to 30% longer than the lengths are mixed by 10 to 20% of the standard bristles, the ball B
Are long hairs 2 protruding above the standard hairs 2a in these coarse states.
b, it is held and prevented from rolling, and is stably held at the placed position.

The trainee who practices the shot is the tilt table 1
2 and the ball B is placed on a golf practice mat of the ball mounting table 17 and the golf club is shaken to practice a shot. At this time, the tilting table 12 and the ball mounting table 17 are moved to the operation panel. It is possible to practice by tilting in any direction by operating the switch.

For example, by turning on a switch, as shown in FIG.
As a result, the ball mounting table 17 is tilted upward via the hinge 18, and the ball mounting table 17 on which the ball is mounted is tilted so as to tilt toward the trainee, as shown in FIG. 5.

Although the stance position at which the player stands is flat, the shot practice can be performed effectively on the assumption that the ball is on an inclined slope or the like. At this time, the ball mounting table 17 is inclined, and the ball B may roll. However, as described above, the ball B is held by the long bristles 2b protruding upward in a rough state from the standard bristles 2a of the mat. Therefore, the player can practice the shot while stably holding the ball B at the position where the ball B is placed.

For example, when practicing iron shots such as a sand wedge and a pitching wedge, the lower part of the club head enters the brush bristle bundle 2 below the ball B and is swung out. The bundle 2 has a very small frictional resistance unlike the synthetic turf made of a polymer elastic body or rubber, so that the club head can be swung relatively easily,
The wear of the brush bristle bundle 2 is also very small, and the life of the golf practice mat can be extended.

In the above embodiment, the mat substrate 1 is formed of a relatively hard synthetic resin plate, but the mat substrate may be formed of a soft synthetic resin or a polymer elastic body. For example, when the mat substrate is formed of a rubber-like polymer elastic body, as shown in FIG. 7, the mat substrate uses the upper mat substrate 21 and the lower mat substrate 22 separately, and uses the metal wires 23. The brush bristle bundle 2 can be stopped.

That is, a number of flocked holes are arranged and perforated in the upper mat substrate 21 in a staggered manner at a predetermined pitch (about 5 mm), and the bundled standard bristles 2a and long bristles are placed in the flocked holes. 2
b is inserted into the folded portion from the middle portion by bending it into two, and the metal wire 23 is inserted into the bent portion from the back side to prevent the wire from being pulled out. Then, the lower mat substrate 22 provided with an adhesive is attached to the back side of the upper mat substrate 21 and adhered. By implanting the brush bristle bundle in this way, even if the mat substrate is a rubber-like polymer elastic body, the brush bristle bundle can be prevented from coming off, and a practice mat can be manufactured.

[0030]

As described above, the present invention is constructed as described above. Therefore, when a mat is laid on an inclined ball mounting table and the ball placed on the mat may roll, The ball is held by long hairs that protrude upward in a rough state from the standard hair, so that the ball can be stably held at the placed position without rolling and the shot practice can be improved. it can. Unlike a conventional polymer turf made of a polymer elastic body, the brush bristle bundle has a very small frictional resistance, and a small number of long bristles hold the circumference of the ball, so that the club head is relatively easy to use. , And the brush bristle bundle can be worn very little, so that the life of the golf practice mat can be extended.
