Almost as it is or artificial grass is filled with joint sand. However, this prior art is weak because the artificial turf mat is coarse after being used for a long time (3 to 4 months), and in this kind of tea ground mat, due to the torsion load, the artificial turf mat is The wrinkles are more torn and the appearance is worse, the durability is poor, and the golf tee is hard to tamp during long-term use, and the golf tee does not stick. Therefore, it is necessary to repeat the laying of the artificial turf mat frequently, resulting in high maintenance cost.

Further, as a golf practice mat, an elastic plate such as a rubber mat laminated to the bottom of a cut pile is found in the market, but it has almost no water permeability and is not suitable for long-term laying outdoors. Is. In addition, it is also possible to use a sponge mat of open cells bonded to each other instead of the rubber plate. The water between the turf fibers cannot be drained, and in rainy weather the artificial turf mat will be flooded, hindering the game. Also, with this structure, the tee cannot be stuck anywhere. Even if it is water-permeable, even the fine open-celled air bubbles retain water, so if you ride on this mat after the rain, the pressure will cause water to seep out onto the artificial grass surface, and the durability of the sponge mat itself will be insufficient. Therefore, it cannot withstand long-term use.

As in the lower layer 14, there may be provided a reinforcing edge 16 in which only the rubber piece 11 is bonded with a binder in the range of 1 to 2 cm around the edge. Alternatively, instead of the reinforcing edge 16, the periphery of the artificial turf mat 20 may be bent along the peripheral wall surface of the base mat layer 10 and bonded integrally with it.

The expanded particles 13 are formed by adding a foaming agent to polyethylene or a copolymer resin of polyethylene and polystyrene and foaming it, and the expansion ratio is 30 to 40.
And the particle size was 3 to 4 mm. The mixing weight ratio of the rubber pieces 11 and the expanded particles 13 was 100; 7.

In a typical embodiment of the artificial turf mat 20, the ground 21 composed of the chain yarn and the inserted yarn is made of a kind such as Russell knitting, and the stitch gap 22 is almost equal to the thickness of the leg portion 30 of the golf tee A. They are the same, and the flat synthetic resin fibers 23 are woven into the chain yarn as a cut pile. Therefore, the artificial grass mat 20
From the surface to the base mat layer 10 has water permeability and is formed so that a golf tee can easily pierce it (see FIG. 3).

Embodiment 3 An embodiment of the method invention according to claim 6 will be described. First, the size of the mat A of the present invention is, for example, 1.5 square meters and the depth is 4
A mold 40 having a size of about cm is prepared, and the artificial grass mat 20 having a size corresponding to the mold 40 is laid in the mold 40 with its surface facing downward, and the periphery of the mold 40 is covered as necessary. It stands up along with the standing wall 41 (see FIGS. 4 to 6). In this case, the notch 24 is provided in advance in the artificial grass mat 20 in the portion that becomes the corner 42 of the mold 40.

Next, stitches 22 are formed on the back surface of the artificial grass mat 20.
Apply binder to the extent that it does not block. Next, the rubber piece 11 and a binder, which is compatible with the rubber piece 11 as a binder and has adhesiveness to the foamed particles 13, for example, an adhesive made of a one-component moisture-curable urethane resin are used in a weight ratio. 30 to 35 parts of the binder is added to 100 parts of the above and mixed, and a thickness of 2 cm to 3 cm is averaged on the artificial grass mat 20 laid in the mold 40. Then, the lid 43 is put on and the binder is solidified while applying a slight pressure. Finally, the artificial turf mat is released from the mold 40 to obtain a product (see FIGS. 1 and 2).

Embodiment 4 An embodiment including the method invention according to claims 7 and 8, wherein
A method different from that of Example 3 is to form the basic mat layer 10, and first, the rubber pieces 11 and the expanded particles 13 are added in a weight ratio of 100 parts of the rubber pieces to 7 parts of the expanded particles 13.
And 37 parts of a binder are added and mixed, and the mixture is spread on the mold 40 to a thickness of 2 cm to 2.5 cm, and the thickness is averaged.

Next, before the binder is solidified,
The same mixture of rubber pieces 11 and binder as in Example 3 was laid on it, the thickness was averaged, and then the lid was closed in the same manner as in Example 3 to wait for the solidification of all the binders.
The product is released from the mold 40. The foamed particles 1 described above
Before filling the mold 40 with the mixture of the rubber piece 11 and the binder 3, the reinforcing edge 16 is formed along the four standing walls 41 of the mold 40 to a width of 1.5 cm to 2 cm to the depth of the mold 40.
May be formed (see FIGS. 8 and 9). Example 3
The product of Example 1 is molded by the method of
The product of Example 2 is molded by the method described above.

Operation of the Example If the mat A, which is the product of the example 1, is relatively small in size, it is used by laying it on the bat at the driving range like a conventional golf practice mat. Larger mats A will be used by laying them on the teeing ground of an outdoor practice field or an actual golf course. When the impactor stands on this mat, the rubber pieces 11 in each crosslinked state are elastically deformed by the treading pressure, and when the treading pressure is removed, the rubber pieces 11 return to the original shape. When the ball is placed on the mat and hit with the club, even if the ball moves in the shearing direction due to friction with the club, the base mat layer 1
Each of the rubber pieces 11 of 0 also elastically deforms in the shearing direction correspondingly and does not overload the artificial grass mat 20 and the club.

Further, rainwater and the like pass through the coarse gaps 15 and are not absorbed, and even when it is raining or after rain, it is drained to the same extent as natural grass. In the product of Example 2, in order to use it, the required number of mats 10 are laid on a tea ground with the artificial grass surface facing upward, and appropriately fixed to the ground with a fixing tool such as a U-shaped nail. The user pierces the tee T on the mat A from the surface of the mat A to at least the upper layer 12 of the base mat layer 10. Therefore, depending on the player's preference, the tee T may be pierced until it penetrates the lower layer 14 as well as the upper layer 12. In this way, the leg portion 30 of the tee T causes the rubber piece 11 of the base mat layer 10 to bend, and the gap 15a thereof elastically deforms and expands, and the tee T
The tee T stands up by sandwiching the leg portion 30 of the. At this time, the top of the tee T is substantially flush with the surface 23 of the cut pile 23 of the artificial turf mat or slightly protruding.

Then, a ball is placed on the top of the golf tee T and struck in the same manner as a normal tee shot. When hit, the tee T falls sideways due to the hitting force, but its leg 3
Since 0 is only supported between the elastic rubber pieces 11, it is laid down with almost no resistance and does not particularly affect the impact. When the tee T is removed, the elastic deformation of the rubber piece 11 is restored. Further, since the artificial grass mat 20 has a coarse mesh 22 and the gland 21 has flexibility, the tee T
At the time of insertion, it is flexed as it is or slightly to the side.

In the mat A of this Example 2, since the base mat layer 10 has the gap 15a and the rubber pieces 11 and the foamed particles 13 are elastically deformed, the mat A has a cushioning property as a whole and rainwater and the like permeate therethrough. To do. Also, the base mat layer 10
Since the lower layer 14 is formed only of the rubber pieces 11, not only the tissue is dense, but also the bond is strong. When the reinforcing edge 17 is provided, the peripheral edge of the mat A is strong, and has sufficient supporting force even when the peripheral edge is fixed by a fixture, and does not collapse from the peripheral edge even by the pedaling pressure. In each embodiment of the invention of the manufacturing method, the above-mentioned embodiment can be manufactured.

[0031]

According to the inventions of the above-mentioned claims 1 and 2, the supporting force against the tread pressure is large, the cushioning property does not deteriorate even after long-term use, and the water permeability is excellent. Because of this, it can be used outdoors in the rain or after rain as much as natural grass. Further, even if sand or the like is clogged in the gap, the gap is rough, so that they can be easily removed by punching or washing with water. According to the invention of any one of claims 2 to 5, the tee can be easily pierced from the surface of the mat into the gap between the artificial turf mat and the base mat portion, and after the piercing, the tee is separated by the elastic restoring force of the rubber piece. It is supported tensely and can fully support the golf ball.

Further, the mat itself has a cushioning property close to that of natural turf due to the above-mentioned structure, and the surface is covered with the artificial turf mat, so that it is extremely strong, and the artificial turf mat and the base mat layer are integrated. It does not wrinkle even if it is hit and hit hard, and its appearance hardly changes for a long time,
Since it can withstand long-term use and has water permeability as a whole, rainwater does not collect on the mat surface, and once installed, no considerable long-term maintenance is required. In the invention according to claim 3, since the mixing ratio of the rubber pieces and the foamed particles is the same as described above, the resistance formed when the gap formed in the base mat layer pierces the tee is small. In addition, it has a proper supporting force for standing up the tee, accurately supports the golf ball, and has a resistance at the time of impact close to that of natural grass.

In the invention according to claim 5, since the bottom surface is formed of a lower layer composed of only rubber pieces, the bottom surface is sufficiently resistant to friction with the tee ground when hit, and the overall shape retention force is further improved. strong.

In the method invention according to claim 6, the mat according to claim 1 or 2 can be molded. Claim 7
In the method invention described above, the mat of the invention described in claims 3 to 4 can be molded. In the method of claim 8, the mat of the invention of claim 5 can be molded. In the invention of each method, by mixing the rubber pieces and the binder, the directions of the rubber pieces become irregular, and the rubber pieces become cross-linked with each other, which is sufficient for the basic mat layer of the molded product. A mat with various gaps and cushioning properties can be molded.

Effects of Embodiments of the Invention Those having the structures corresponding to the respective claims not only exhibit those effects, but those of which the peripheral surface of the mat A is also covered with the artificial grass mat 20 have a peripheral edge. It is strong and even when many mats A are laid, the mats will not be damaged because shoes or clubs are caught in the seams. When the rubber pieces 11 that are cut out from industrial waste such as old tires are used, the resources can be effectively reused and the product becomes inexpensive.
