[0002]
[Prior art]
Conventionally, artificial turf laid in places for skiing, ski jumping in summer, playing with kites in amusement parks and resort facilities, and water shoots are made of plastic on a cushioning material such as foamed polyethylene resin bonded onto a concrete base. Adhere a roll-shaped artificial lawn with an innumerable number of grass leaf-like pieces planted, or directly attach a roll-shaped artificial lawn with an infinite number of plastic grass-leaf pieces planted on cushioning material to a concrete base It was normal to do. However, plastic turf leaves tend to wear out due to skiing, scissors, etc., and cannot be used for a long period of time. Generally, it is necessary to replace the artificial turf every several years, which increases maintenance costs. There was a problem. Moreover, when partially repairing a damaged artificial lawn, the minimum basic unit of a roll-shaped artificial lawn is 1m x 30m size, so the repair work of repair is important and the cost is high, and the maintenance cost is high. There was a problem. In addition, when using it for playing with kites, skiing, ski jumping, etc., if you spray water on the surface of the artificial lawn and do not apply a lubricant such as silicone oil to the skis or the kite, slipping will be bad, Since the trouble that the lawn melts due to frictional heat occurs, the application work and the water spraying work are indispensable, and there is a problem that the cost required for this work and the lubricant increases and the running cost increases.

DETAILED DESCRIPTION OF THE INVENTION
Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings.
Reference numeral 1 denotes a slide unit having a horizontal width of 990 mm and a vertical width of 510 mm. The slide unit 1 includes a large number of brush-like wire rod portions 2 and a plastic plate portion 4, and the wire rod portion 2 is a plastic made of polypropylene resin having a diameter of 2 mm. A large number of wires 2a are bundled, and the upper edge thereof is insert-molded into a fastening plate 2b made of polypropylene resin and fixed in a brush shape. Further, the plastic wire 2a is waved to reduce the contact surface with the bag or ski so that the frictional resistance is reduced. The plastic plate portion 4 is made of a polypropylene resin plate 4a attached to the surface of the slide member 1, and the plate 4a has a vertical width shorter than the vertical width of the wire portion 2 and is below the plate 4a. The plastic wire 2a is projected from the edge. A number of reinforcing ribs 4b extending in the vertical direction are formed on the lower surface of the plate body 4a. The reinforcing rib 4b is formed in the central portion of the plate body 4a and has a tapered shape that increases from the upper side toward the lower side, and the fastening plate 2b of the wire portion 2 is superimposed on the flat upper upper surface of the plastic plate portion 4. The fastening plate 2b of the slide unit 1 laid on the lower side of the lower surface of the plastic plate portion 4 which is arranged and bulges in a taper shape is arranged so as not to be uneven at the overlapping portion between the slide units 1. I am doing so.
[0006]
5 is a cushioning material made of foamed polyethylene resin having a thickness of about 20 mm, which is attached to an inclined base surface 6 constructed of concrete or wood, and 7 is a mesh of about 39 mm square which is attached to the surface of the cushioning material 5. A net material made of polypropylene resin, and the buffer material 5 and the net material 7 are arranged by appropriately arranging a metal band 8 attached to the net material 7 by partially under the net yarn. It is fixed to the inclined base surface 6 by driving a nail or a bolt through the retaining hole of the metal band 8, but the overlapping portion of the adjacent net material 7 is always fixed by the metal band 8 and the net material. 7 is not lifted up. Reference numeral 9 denotes a fixing member for integrally connecting and fixing the wire portion 2, the plastic plate portion 4, and the net member 7. The fixing member 9 forms a tooth 9b on the upper surface of the belt 9a and a ring through which the belt 9a is inserted. A binding member made of polypropylene resin in which a claw that engages with the tooth 9b only in the retaining direction is formed on the portion 9c. Reference numerals 10 and 11 denote through-holes for passing the belt 9a of the fixing member 9 that is provided through the upper edges of the fastening plate 2b and the plate body 4a.
[0007]
In the structure configured as described above, the cushioning material 5 made of foamed polyethylene resin is laid on the entire inclined base surface 6 constructed of concrete or wood. Subsequently, the net material 7 is laid on the upper surface of the buffer material 5. At this time, a part of the periphery of each net member 7 is overlapped. Then, a metal band 8 that partially hides the lower side of the net yarn is applied to the overlapped portion of each net material 7 and a required place, and a nail or a bolt is passed through a retaining hole of the metal band 8 to attach wood or concrete. The net material 7 and the buffer material 5 are fixed to the inclined base surface 6.
[0008]
Next, the plate body 4 a is placed on the net member 7, and the slide unit 1 is formed on the plate body 4 a by aligning the upper edge and attaching the wire portion 2. Then, the belt 9a of the binding tool as the fixing member 9 is passed through the net member 7 through the through holes 10 and 11 of the fastening plate 2b and the plate body 4a, and the drawn belt 9a is inserted into the ring portion 9c and tightened. Then, the belt 9a is engaged and fixed to the ring portion 9c by the teeth 9b of the belt 9a and the claw of the ring portion 9c that are engaged only in the retaining direction, and the plate body 4a is attached to the lower surface of the wire portion 2. The slide unit 1 is fixed to the net member 7. When a large number of the slide units 1 are arranged in parallel on the inclined base surface 6 in this way, the lower plate portion 4b of the upper stage plate 4a to be laid next is concealed with the fastening plate 2b portion of the lower stage slide unit 1. In addition, the protruding portion of the wire portion 2 of the slide unit 1 is positioned so as to be disposed on the upper surface of the plastic wire 2a of the lower slide unit 1, and further, the left and right overlapping portions of the slide unit 1 laid on the lower step Are arranged in a staggered manner so that the central portion of the upper slide unit 1 is located on the upper part of the slide unit. In the same manner as described above, the wire portion 2 and the plate body 4 a of the slide unit 1 are fixed to the net member 7 with the fixing member 9. Thereafter, the slide unit 1 may be laid on the entire inclined base surface 6 in the same manner.
[0009]
This is because the upper surface of the slide unit 1 laid on the entire surface of the slope is composed of a large number of brush-like plastic wires 2a. Even when skiing or sliding is performed, the bundled plastic wire 2a disperses the load caused by skiing or heeling, so that a large load is not applied only to a part of the plastic wire 2a. Smooth skidding can be obtained without applying the agent to skis, scissors or the like, or spraying water on the slide unit 1, and severe wear can be prevented. Further, since the plastic wire 2a is formed in a wave shape, the contact area with the ski and the heel is small and the frictional resistance is reduced, so that the sliding is smoother and wear can be more reliably prevented. Further, the plate body 4a on the lower surface of the wire portion 2 accurately prevents the user from falling over due to the ski board or the bag coming into contact with the net member 7 or the like even if the plastic wire 2a is partially peeled off. In addition, when the slide unit 1 is worn out partly, it is not easily worn out by removing the fixing member 9 of the slide unit 1 where the wear is severe, turning the wire portion 2 over and stopping again with the fixing member 9. The slide unit 1 can be configured with the new rear surface facing the front surface. And it is only necessary to replace the slide unit 1 with a new one only when the front and back surfaces are worn out. In the preferred embodiment, the fixing member 9 is used as a binding tool. However, the fixing member 9 may be fastened to the net member 7 with a wire or the like. The slide unit 1 may be fixed by stopping.

【The invention's effect】
As is apparent from the above description, the present invention uses a slide unit in which a wire portion , in which a large number of plastic wires are bundled in a brush shape and fixed at the upper edge thereof, is attached to the surface of the plastic plate portion, thereby providing a conventional artificial lawn. Further, the durability can be greatly improved and the wire portion can be turned over so that it can be used for a long time. In addition, the brush-like wire portion disperses the load, applies the lubricant to the skis, the heels, etc., and can smoothly run without spraying water on the slide unit 1, thereby reducing running costs. In addition, the wear of the plastic wire is also reduced. In addition, by attaching a plastic plate part to the back of the slide unit, even if a situation where the wire part is peeled off, the ski board and the bag do not come into direct contact with the net material. It is possible to reliably prevent the ski board and the saddle from falling over , and in particular, the plastic plate portion of each slide unit is placed on the back surface of the plate body whose vertical dimension is shorter than the length of the wire portion described above. is assumed that a plurality of tapered reinforcing ribs increases toward the lower side from the side is provided, the lower portion of the the wire section Yes allowed out Zhang the lower edge of the plate body, such slide unit The upper part of each slide unit forming a lower row by being aligned horizontally in the lower portion thereof by the lower portion of the wire portion of each slide unit that is arranged in a horizontal row and forming the upper row Since being concealed are laid in a zigzag shape as a state, causing no unevenness in the superposed section of between slide unit. Furthermore, since a large impact can be absorbed by fixing the net material via a cushioning material, it can also be used for ski jumping and the like, and can also absorb an impact when falling. Further, by making the wire portion into a brush shape and making the plastic wire into a wave shape, the contact area with the ski and the heel is further reduced, so that smoother sliding can be obtained. In addition, by using the fixing member, it is not necessary to use an adhesive at the time of construction, so that it is preferable for the health of the worker, and repairs such as partial replacement can be performed easily and inexpensively. In addition, if the fixing member is a binding tool, it has various advantages such that it can be easily constructed and repaired by hand without using a tool.
Therefore, the present invention greatly contributes to the development of the industry as an artificial grass for sliding that solves the conventional problems.
