Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to artificial turf made of synthetic resin, and particularly to an artificial turf having an edge member attached to at least one edge thereof.

(Prior Art) Examples of artificial turf structures that have been subjected to edge-containment treatment include Utility Model Application No. 120632/1982 and Publication No. 32799/1983.

In the former method, the peripheral edge of the base plate placed on the underside of the artificial turf is used as a protruding edge on the frame, a concave part opening inward is formed in the protruding edge, and the edge of the artificial turf is inserted into this part. This is what I did.

In addition, the latter has a large number of pointed locking claws erected on the top surface of the metal substrate to be inserted into the bottom surface of the artificial turf, and a holding piece with a U-shaped cross section made of a suitable soft synthetic resin is formed on the edge side. The edge of the artificial turf is held between the holding pieces while the pointed locking claws are inserted into the bottom surface of the artificial turf.

(Problem to be solved by the invention) However, in the former case, simply due to the upward repulsive force of the raised artificial turf itself and the elasticity of the ridge,
Because the edge of the artificial turf is held in the recess, it is easy for the rug to fall out of the recess, and when a person steps on the edge, the edge cannot support this load and falls downward. It was concave, giving a sense of discomfort to pedestrians, and furthermore, the raised portion within the protrusion was pressed, weakening its repulsive force and making it easier to fall out.

In addition, in the latter case, the fixing action of piercing the locking claw into the artificial turf and the sliding action of rolling the edge into the holding piece must be performed at the same time, making installation work difficult. There were problems such as it was difficult to readjust the arrangement, and the artificial turf had holes and the locking claws were deformed, making it difficult to disassemble and reuse.

The present invention solves the above-mentioned drawbacks, and provides an artificial turf with an edge member that makes it easy to attach the edge member to the edge, securely locks the edge of the artificial turf, and prevents the edge from denting even when a load is applied from above. We aim to provide the following.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a base part, a large number of grass leaf-like strips are planted in blocks on the base part, and a predetermined distance between the blocks is provided. an artificial turf made of flexible synthetic resin having parallel gaps provided at each interval; and an edge member having at least a top surface and a bottom surface; the inner edge of the top surface of the edge member is bent downward to form a hanging engagement piece; A gap equal to at least the thickness of the base surface of the artificial turf is provided between the lower end and the bottom surface of the hanging engaging piece, and at least one block portion along the edge of the artificial turf can be press-inserted between the upper bottom surface of the hanging engaging piece. The artificial turf with an edge member is constructed by an edge member formed with a cavity.

(Function) Place one end of the edge member against one side of the artificial turf, press-fit at least one block along the edge of the artificial turf into the cavity of the edge member, and at the same time insert the hanging engagement piece of the edge member into the artificial turf. If the edge member is inserted so as to bite into the gap in a line between the blocks and both are slid in the longitudinal direction of the edge member, the two will be engaged as if meshing. The end face of the edge member may be closed with a stopper or the like, if necessary, or abutted against an extending or intersecting edge member.

(Example) Hereinafter, an example of artificial turf with edge members according to the present invention will be described based on the drawings, but the present invention is not limited to the following examples unless it exceeds the gist thereof.

Fig. 1 is a partially omitted perspective view of the edge member and artificial turf combined, Fig. 2 is a partially enlarged side view of the state before the two are combined, and Fig. 3 is a partially enlarged side view of the state after the two are combined. It is a diagram.

Reference numeral 1 denotes an artificial turf with an edge member, which is composed of an artificial turf 2 and an edge member 3 attached to the edge of the artificial turf 2.

The artificial turf 2 is molded from a flexible synthetic resin, and includes a plate-shaped base portion 4 and grass leaf-like strips 5 planted on the base portion 4 to form a large number of grass-like blocks 6. A gap 7 having an appropriate interval is formed between the large number of blocks 6, and the base portion of the gap 7 is formed to be slightly thicker than other base portions as necessary. . The grass leaf-like strips 5 are formed by dividing a cylindrical peripheral wall that is integrally planted on the base portion 4 into elongated strips with tapered upper ends and slightly rounded shapes, but any other grass-like shape may be used. It can be configured as follows. Further, a protective sheet 8 such as a polymeric sheet of loosely woven cloth and thin paper may be fixed to the lower surface of the base portion 4 as required.

The edge member 3 includes a band-shaped bottom surface 9 and a top surface 10, a hanging engagement piece 11 bent downward from the inner edge of the top surface 10, and a rib 12 standing longitudinally in the middle between the top and bottom surfaces.
Flexible synthetic resins, such as olefin resins such as polyethylene and polypropylene, styrene resins such as polystyrene, rubber-reinforced polystyrene, and ABS resins, vinyl chloride resins, polyamides, and polycarbonates. , polyesters, etc. may be used alone or in combination depending on the material, or may be manufactured from aluminum or other appropriate metal materials.

The upper surface 10 of the green member 3 has approximately half of the outer edge side sloped downward, and the outer edge is a converging inclined surface continuous with the bottom surface 9, and approximately half of the inner edge side is a horizontal surface, and the height between the horizontal surface and the bottom surface 9 is The height is lower than the standing height of the grass leaf-like strips 5, preferably about 1/2 to 2/3 of the height. The hanging engagement piece 11 is formed with a gap slightly wider than at least the thickness thereof so that the base part 4 of the artificial grass 2 can be slidably inserted between the lower end and the bottom surface 9, and the inner side thereof A cavity 13 is formed in a portion surrounded by the upper bottom surface and the ribs 12, into which at least one row of blocks 6 along the edge of the artificial turf 2 can be inserted.

Thus, in the artificial turf 1 with an edge member of the present invention, one end of the edge member 3 is pressed against one side end of the artificial turf 2, and at least one block portion along the edge of the artificial turf 2 is pressed against the edge member 3. While press-inserting it into the cavity 13, insert the hanging engagement piece 11 of the edge member 3 so as to bite into the gap 7 in a line between the block 6 press-inserted into the cavity 13 and the block 6 adjacent thereto; When the edge member 3 is slid in the longitudinal direction, the 5 groups of grass leaf-like pieces of the press-inserted block 6 deform as if crushed, form a mass, press against the edge member 3 from the inside of the cavity 13, and hang down. It engages with the engagement piece 11 so as to mesh with it. An adhesive layer may be formed on the bottom surface of the edge member 3 and, if desired, the lower surface of the artificial turf 2, or a non-slip member may be formed in advance, and then the anti-slip member may be provided at a desired location such as the floor surface.

A cavity 13 is formed on the end surface of the edge member 3 as necessary.
The artificial turf 2 can be prevented from sliding by fixing a stopper that closes the edge of the artificial turf 2 or a stopper that is approximately the same shape as the end surface, or an edge member can be attached to the block row that intersects the block row to which the edge member 3 is attached. Put on the
Both edge members may abut against each other to form a corner part,
The edge member 3 may be attached to the entire periphery of the artificial turf to form a picture frame shape.

Therefore, the artificial turf with edge members 1 of the present invention can be installed simply by press-inserting the row of grass-like blocks 6 into the hollow portion 13 of the edge member 3 and sliding it longitudinally, making the installation of the edge member 3 extremely easy.
Similarly, it can be easily removed by simply sliding it, but the edge member 3 will not come off in a direction intersecting the sliding direction, and the edge of the artificial turf to which this edge member 3 is attached will not be turned over.

In addition, since the upper surface 10 of the edge member is supported by the ribs 12 and the hanging engagement piece 11 which holds the base portion 4 of the artificial turf 2 at the lower end, the edge member may be stepped on by people. Even if a large load is applied to the upper plate, it will not be dented or distorted, and the hanging engagement piece 11 will be deformed, the gap 7 at the lower end will widen, and the engagement with the artificial turf 2 will be disengaged. Nor.

The protective sheet on the underside of the artificial turf does not damage the artificial turf itself or the flooring material when the artificial turf is rolled up or moved when it is unrolled. Even when attaching grass to a floor surface, the protective sheet helps to increase its adhesive strength.

In the above embodiment, the outer edge side portion of the edge member 3 may be made solid instead of the rib 12, and a cavity for thinning may be provided within this solid portion. A configuration may also be adopted in which there is no portion on the outer edge side of the rib 12.

It is also possible to attach a non-slip material to the top surface of the edge member to prevent slips, or to form unevenness on the top surface of the edge member.Furthermore, it is also possible to form turf leaf-like strips, similar to artificial turf, in an upright manner on the bottom surface. A protrusion or the like may be formed to prevent slipping.

Furthermore, the structure of the grass blade-like strips is not limited to the above embodiments, and may be arranged in any desired manner as long as parallel gaps are formed along the edges.

(Effects of the invention) As described above, according to the artificial turf with edge member of the present invention, the edge member can be easily attached to the artificial turf, and the bonded state after attachment is strong, so that the artificial turf can be easily attached to the artificial turf. Even if a force is applied in the direction of separating the artificial turf and the edge member, the artificial turf and the edge member will not turn over or separate, and the initial bonding strength can be maintained even after long-term use. In addition, the edge members are easy to install and remove, and the size of the artificial turf and the length of the edge members can be easily changed according to the size of the place where it is installed, and if the artificial turf or edge members are damaged. But it can be easily replaced,
Furthermore, even if it becomes necessary to change the arrangement, it can be easily done, and the workability can be significantly improved.

Further, according to the present invention, even if the edge member is stepped on, it will not be greatly dented or distorted, so it will not give a sense of discomfort to pedestrians, and the usability can be improved.
