Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a tee ground for park golf.

[0002]

2. Description of the Related Art Park golf is a kind of golf game that has been recently introduced, and the size of a ball to be used is about twice as large as that of a normal golf ball and approximately the same size as a ball for a softball baseball. , The club for the impact also has a large head,
Use a type that puts emphasis on the direction of the hit ball, similar in shape and function to the putter, and can be played outdoors even if there is only a small space, especially the entertainment that can be played indoors High golf.

A golf tee ground is generally made of natural grass vegetation. Particularly in a park golf played indoors and outdoors, the tee ground is used as an indoor tee ground to improve the hitting property of the ball. In addition, some kind of rug is required. As the rug, the artificial turf for golf practice or the artificial turf for a gate ball cannot be used as it is because the artificial turf may be severely worn or the floor of an indoor facility may be damaged.

As a general golf tee ground, for example, Japanese Unexamined Patent Publication No. 3-244483 discloses an artificial turf structure for golf tees in which artificial turf is laminated on the surface of a foamed resin base mat reinforced by mixing fibers. Have been. Since a general golf tee ground is used by piercing several hundred Tipec a day, the golf tee ground is strongly required to have the piercing property of the Tipec and its durability. Is intended to hit a tee-up ball.
In the artificial turf structure for golf tee-up disclosed in Japanese Patent No. 4483, the base mat is laminated on the crushed stone at the bottom, and the artificial turf is further laid on the base mat, and the outer peripheral end of the artificial turf is backfilled. It can be easily configured by pressing and fixing the surrounding soil around the base mat. Therefore, when using such a general golf tee ground to play park golf that hits a ball that has not been tied up, there is a problem of adhesion between the base material and the artificial turf and the hitting property of the ball on the artificial turf. The problem, that is, if the tee shot is duffed, the base material and the floor below may be damaged to an irreparable degree.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above facts, and has as its object to easily perform a tee shot and to reduce the degree of damage even if a mistake is made. It is an object of the present invention to provide a park golf tee ground that has excellent portability and storage properties.

[0006]

According to the first aspect of the present invention,
The gist of the present invention is a tee ground for park golf, wherein an artificial turf is laminated on a base material including a hard plate-like reinforcing material.

[0007] The invention according to claim 2 provides a park golf tee according to claim 1, wherein the hard plate-like reinforcing material is plywood.

[0008] The hard plate-like reinforcing material used in the present invention is not particularly limited as long as it is capable of imparting appropriate rigidity to the base material so that the player can swing the club head smoothly on a stable scaffold. However, for example, a plywood or the like may be used as in the park golf tee ground according to the second aspect of the present invention.

The invention according to claim 3 is characterized in that a rubber sheet layer is laminated on the upper and lower surfaces of the synthetic resin foam and the plywood of the laminate comprising the synthetic resin foam and the plywood, and The gist of the present invention is a park golf tee ground in which artificial turf is laminated on a rubber sheet surface.

[0010] According to a fourth aspect of the present invention, the entire surface of a laminate comprising a synthetic resin foam and plywood is covered with a rubber sheet layer, and artificial turf is laminated on the rubber sheet surface on the plywood. The gist of the present invention is a tee ground for park golf, which is characterized by the following.

The synthetic resin foam used in the present invention is not particularly limited, but examples thereof include a vinyl chloride resin foam, a styrene resin foam, a polyethylene resin foam, and a polypropylene resin foam. And the like. The compressive strength of these synthetic resin foams is
The value measured according to JIS K 7220 is 50
It is preferably about 5,000 g / cm ² . still,
The compressive strength of the synthetic resin foam is indicated by the compressive strength at 5% strain or yield strain.

According to a fifth aspect of the present invention, there is provided a park golf tee according to the third or fourth aspect, wherein the synthetic resin foam is a styrene-based resin foam. Things.

The styrene-based resin foam used in the invention according to the fifth aspect is a foam having different properties depending on the type of the production method, the type of the foaming agent used in the production method, and other elements of the production process. Although it shows high compressibility as a whole, it not only gives a comfortable feeling of use, but also because it is lightweight, it is easy to prepare for the course before and after play, and it has excellent storage stability of the tee ground that can be cleaned up Become.

Among the above-mentioned styrene-based resin foams, a synthetic resin foam called a styrene foam board is mainly composed of a styrene resin and a styrene resin, and is made of a styrene resin composition obtained by blending another resin or graft-polymerizing. The resulting styrene-based resin beads are impregnated with an inflatable swelling agent or solvent such as propane, butane, pentane or hexane, and heated and pressed in a foaming mold to form a foamed closed-cell foam. Since each cell of the foam forms a lattice structure, it is presumed that the foam exhibits high compressibility as described above.

[0015] The plywood includes all plate-like bodies made of multi-layer processed wood in which warp, distortion and cracks caused by the warp and the like are suppressed during use. For example, Japanese Agricultural Standards (JAS) ) Is preferably used. The thickness of the plywood is appropriately set according to the properties of the synthetic resin foam used,
Although not particularly limited, for example, 2.7 to 15
Plywood having a thickness of about mm is preferably used. If the thickness of the plywood is less than 2.7 mm, the mechanical strength is low and it is not sufficient for repeated use. Even if the thickness exceeds 15 mm, there is no problem in the ball hitting property or durability. However, not only does it not require any additional thickness, but it also becomes heavier as a whole, so that portability in preparation after play becomes an issue.

The means for laminating the synthetic resin foam and the plywood includes:
Although not particularly limited, for example, a method of subjecting the synthetic resin foam and / or plywood to an undercoating treatment and other surface treatments, and pressing and laminating with an adhesive may be mentioned.

The rubber constituting the rubber sheet layer is:
There is no particular limitation as long as it adheres to the synthetic resin foam and the plywood. For example, natural rubber, recycled rubber, styrene butadiene rubber (SBR), acrylonitrile butadiene rubber (NBR), butyl rubber (II)
R), chloroprene rubber (CR), butadiene rubber (B
R), isoprene rubber (IR), fluoro rubber, ethylene propylene rubber (EPM, EPDM), chlorosulfonated polyethylene, silicone rubber, urethane rubber, polysulfide rubber, acrylic rubber (ACM, ANM), propylene oxide rubber, epichrom Hydrin rubber, trans-
1,5-polypentenamer (t-PA) and the like.

The thickness of the rubber sheet layer is appropriately determined depending on the properties of the artificial turf to be used, which will be described later, and is preferably 1 to 30 mm. When the thickness of the rubber sheet layer is less than 1 mm, it is difficult to sufficiently adhere to the back surface of the artificial turf having severe irregularities, and the adhesive strength at the time of lamination is reduced. In this case, the surface properties of a preferred plywood may be impaired, and it may be difficult to obtain a favorable ball hitting property.

The artificial turf forming the surface layer of the tee ground is obtained by splitting (fibrillating) a monofilament or polypropylene film of polypropylene, polyamide, polyvinylidene chloride or the like on a base cloth made of synthetic fiber such as polyester or polypropylene. Twisted into the fiber in advance,
It is a woven fabric that resembles natural turf in which turf leaves with a pile length of 5 to 15 mm are densely planted by tuft-weaving pile yarns that have been subjected to crimping or the like. The back of the tufted base fabric is coated with a synthetic rubber so that the grass leaves made of the pile yarn do not fall off, but regular irregularities are formed by the tufted weave. I'm done.

The means for laminating the artificial turf on the plywood surface of the laminate composed of the synthetic resin foam and the plywood via the rubber sheet layer is not particularly limited. For example, an adhesive may be used. And a method of laminating under pressure.

As described above, the tee ground for park golf according to the first aspect of the present invention is such that the artificial turf is laminated on the base material including the hard plate-like reinforcing material, so that the player is stable. And the club head can swing smoothly. In particular, in the tee ground for park golf according to the first aspect of the present invention, since the hard plate-like reinforcing material is plywood, the rigidity of the plywood, the elasticity of the base material, and the artificial turf are very comfortable. You can enjoy a nice tee shot.

According to a third aspect of the present invention, there is provided a tee ground for a park golf, wherein a rubber sheet is laminated only on the upper and lower surfaces of a synthetic resin foam of a laminate comprising a synthetic resin foam and plywood, and plywood. Therefore, as shown in FIGS. 1 and 2, the rubber sheet layer 21 laminated on the outer surface of the laminate 1 on the synthetic resin foam 11 side is
The artificial turf 3 laminated on the outer surface of the laminated body 1 on the side of the plywood 12 via a rubber sheet layer 22 is laminated on the four sides 13 of the laminated body 1 so as to protrude by about 50 mm on each side. , 13,... Are wrapped around and overlap and adhere to the rubber sheet layer 23 on the synthetic resin foam side protruding by about 50 mm on each side, so that the four side surfaces 13, .. May be formed with ears 4, 4,.
