Description

  The present invention relates to a connection structure for laying boards laid on a floor surface or the ground.

In recent years, square artificial turf boards that can be increased or decreased by connecting them have become widespread, and are used for various purposes and applications on the rooftops of gardens and buildings.
In addition, in response to this background, there are also laying boards that can be connected with such artificial grass boards in a compatible manner. And aesthetics are being improved.
In addition, products that have been laid on the balcony or poolside alone for the laying board, and products with enhanced makeup by attaching a tile board or wood board to the upper surface of the board are also considered.
Resin boards such as artificial turf boards and laying boards are mostly made of soft, shape-retaining synthetic resin materials, artificial turf boards, artificial turf boards and laying boards, and laying boards. The board-to-board connection structure is such that a ring-shaped locking receiving part is formed on the connection receiving side of one board to be connected, and a locking claw corresponding to the locking receiving part is formed on the connection side of the other board to be connected So that the locking body is forcibly shifted to the engaging state by using the elastic deformation of the locking receiving portion and the material of the locking body itself. By fitting, the boards can be connected to each other (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 9-88305 (page 2-3, FIGS. 2 to 7)

However, this kind of board connection structure is connected in a forced fit state using elastic deformation and locking structure once the boards are connected, so this kind of board is used when releasing the connection state Using the elastic deformation of the soft resin itself, the engagement state between the engagement receiving portion and the engagement body is forcibly released by force.
For this reason, this type of board connection structure has a product tendency that it is difficult to connect even during connection, and it is difficult to release the connected state. There are problems of poor separation and connection quality.
It is also possible to use a hard synthetic resin material as the material, but in this case, due to the characteristics of the material, the elastic deformation of the material itself is small. Because a large force concentrates on the local part said, there is a problem that cracks and cracks occur in such a part, and in order to solve this, there is a lot of play in engaging and receiving the lock It is conceivable that the engaging portion of the locking portion and the engaging portion can be easily connected and separated, but in this case, a gap is formed between the boards in the connected state, and an unstable connected state with rattling There is a problem.
Therefore, this type of board-to-board connection structure is made of a soft synthetic resin material, and in terms of usage, it is a product for limited use such as an attached board that can be connected to artificial grass boards. There is a problem.
