Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an artificial lawn in which a large number of synthetic resin lawn pieces are laid abutting each other vertically and horizontally.

[Conventional technology and its problems]

Artificial lawns made of synthetic resin are easily charged with static electricity when people walk on them, and when a person walking on the artificial lawn touches a metal object, the static electricity is discharged and they receive a shock. Sometimes.

For this reason, as a means of discharging the static electricity accumulated in artificial lawns made of synthetic resin, conventional methods have been to form the entire artificial lawn with conductive resin, or to inject conductive resin into the leaf bodies made of ordinary synthetic resin. There is a method of interspersing the thus formed leaves.

However, forming the entire artificial lawn from conductive resin has a problem in that the unit price of the product is extremely high.

In addition, in the case where the leaves made of conductive resin are scattered, there is no electrical connection between the lawn pieces or between the conductive leaves of each lawn piece. The surface area of the leaves is small, so we cannot expect much corona discharge effect.

Therefore, this invention aims to effectively discharge the static electricity accumulated in an artificial lawn, which is made by laying a large number of rectangular synthetic resin lawn pieces abutting each other vertically and horizontally.

[Means to solve the problem]

In order to solve the above problem, the method taken by this invention is to provide continuous conductive leaf parts made of conductive resin in the grass-like leaf body so as to cross the lawn piece vertically and horizontally. , when a lawn piece is laid against the end of this conductive leaf body,
A joint portion was formed to be connected to the end of the conductive leaf body portion of the other lawn piece.

[Effect]

By the above method, when a large number of lawn pieces are laid abutting each other, the conductive leaf parts that cross each lawn piece are connected to each other by the joint parts, so that the overall surface area of the conductive leaf parts is reduced. Therefore, corona discharge is effectively carried out depending on the surface area, and charging of the artificial lawn is effectively prevented.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The artificial lawn according to this invention is constructed by laying a large number of rectangular lawn pieces 1 abutting each other vertically and horizontally.

The lawn piece 1 includes a lawn piece body 2 formed of EVA resin (a copolymer of polyethylene and vinyl acetate), and a conductive leaf body made of conductive resin that is detachably attached to the lawn piece body 2. It is composed of 3 and 3.

The lawn piece main body 2 has a large number of lawn-like leaves 5 formed on the surface of a grid-like substrate 4,
The substrate 4 is divided into nine blocks, and the blocks are connected to each other by a connecting portion 6, and the connecting portion 6 is formed with a pair of leg pieces 7 so as to protrude toward the back side. On the opposite sides of the substrate 4,
A connecting hole 8 and a connecting protrusion 9 are formed which are connected to each other when the lawn pieces 1 are butted and laid.

The conductive leaf part 3 consists of a base frame 10 in which a large number of rectangular frames are lined up in a straight line, and a leaf part 11 erected on the surface of the base frame 10.
It is formed in a grid shape to partition nine blocks. A large number of frame members constituting the base frame 10 are formed to fit snugly into leg pieces 7 formed at connecting portions 6 between the blocks of the substrate 4. Further, the frame body of the base frame 10 is formed with engagement protrusions 12 that engage with the connecting portions 6 that connect the blocks of the substrate 4 at predetermined intervals. It is designed to be fixed on the back. Further, the leaves 11 of the conductive leaf part 3 are arranged in a state where the base frame 10 is fixed to the back surface of the substrate 4.
The leaves 11 protrude from between the blocks of the substrate 4 toward the surface side of the substrate 4, and form a lattice pattern in the lawn-like leaves 5 of the lawn piece body 2.

A lattice-shaped base frame 1 constituting the conductive leaf portion 3
Each end of the grass 0 has a joint concave portion 13 and a joint convex portion 14 that are connected to each other when the lawn piece 1, which is a combination of the lawn piece body 2 and the conductive leaf body portion 3, is butted and laid. A joint portion 15 is formed.

When laying the artificial lawn according to this invention, first, the conductive leaf body part 3 is attached to the lawn piece main body 2 from the back side, and the lawn piece 1 is assembled. and,
Arrange this lawn piece 1 vertically and horizontally and each lawn piece 1
The connecting hole 8 and the connecting protrusion 9 are connected, and the conductive leaf body parts 3 of each lawn piece 1 are connected to each other by the joint part 15. In this way, the artificial lawn is laid.

[Effect of idea]

According to this invention, as described above, when the lawn pieces are laid out in rows and columns, the conductive leaf portions that cross the surface of each lawn piece are electrically connected to each other. The surface area of the conductive leaf body portion is large, and the effect is that the electrostatic corona discharge effect can be maintained at a high level over the entire surface of the artificial lawn.

Furthermore, since the conductive leaf portions of each lawn piece are connected to each other, if the conductive leaf portion of one lawn piece is grounded, charging of the artificial lawn can be more effectively prevented.
