Description

[Detailed description of the invention] This invention relates to an improvement of a mosaic parquet board.

Mosaic parquet boards used as surface materials for floors in schools, kindergartens, offices, etc. have traditionally been made of wood such as beech, tiger, and cherry. However, since this mosaic parquet floor is usually waxed or otherwise applied when cleaning, children and others tend to slip on it, and this tendency becomes even more pronounced when a slope hits the floor.

The mosaic parquet board of this invention eliminates the above-mentioned slipping while walking without sacrificing ease of construction or good finish, and also prevents deformation of the floor surface due to temperature changes after construction. It was proposed with the aim of A horizontally continuous groove is formed on the back side of both unit pieces, and all the wires are buried in the groove.

To explain this invention based on the embodiment shown in the drawings, 1 is a rectangular unit piece made of wood, made of beech, oak, etc.
Made from cherry blossoms, etc. In the present invention, in addition to this unit piece 1 made of wood, a rectangular unit piece 2 made of a hard rubber-like elastic material and having the same shape as the unit piece 1 is prepared. The unit piece 2 made of a hard rubber-like elastic material is made of a polymeric material such as synthetic rubber or synthetic resin, and its surface can be formed to have a similar pattern or color to the surface of the wood unit piece 1. shall be. In order to make the surface of the unit piece 2 made of rubber-like elastic material wood-like,
The entire body may be formed to have a wood-like appearance, or a thin layer of wood-like appearance may be applied on the main body.

Both unit pieces 1 and 2 as described above are first mixed appropriately and then arranged closely in a large number in the lateral direction. In this arrangement, the mixing ratio of the unit piece 2 made of hard rubber-like elastic material to the unit piece 1 made of wood may be determined arbitrarily, and the arrangement of the unit piece 2 made of hard rubber-like elastic material with respect to the unit piece 1 made of wood is as follows: It can be done at regular intervals as shown in the figure, or it can be done at random.

On the back surfaces of both unit pieces 1 and 2 arranged as described above, an arbitrary number (two rows in the illustrated example) of continuous grooves 3 are formed in the horizontal direction, and aluminum wires or other metal wires 4 are formed in the grooves 3. A mosaic parquet board is obtained in which the unit pieces 1 and 2 are interconnected.

In the figure, reference numeral 5 indicates a protruding strip provided at one end of the mosaic parquet board, and reference numeral 6 indicates a groove provided at the other end of the mosaic parquet board. It is used to fit together in order to join.

Note that it is desirable that the compressive strength of the unit piece 2 made of hard rubber-like elastic material is comparable to the compressive strength of the unit piece 1 made of wood to be incorporated together. The reason for this is to avoid giving pedestrians a sense of discomfort, and if the unit piece 2 made of rubber-like elastic material is too soft, pedestrians may get caught on the edge of the adjacent unit piece 1 made of wood. This is to prevent this from happening.

According to the above-described mosaic parquet board of this invention, when it is used as a floor surface, pedestrians' slippage is prevented by the unit pieces 2 made of hard rubber-like elastic material inserted between the unit pieces 1 made of wood. The friction provided by the However, since the amount of deformation is absorbed by the unit piece 2 made of rubber-like elastic material incorporated into the unit piece 1 made of wood, the floor surface will not be curved and deformed, and it will remain stable for a long time. This has the effect of providing a smooth floor surface.

[Scope of utility model registration request] Rectangular wood unit piece 1 and its wood unit piece 1
A large number of rectangular hard rubber-like elastic material unit pieces 2 mixed with the above are arranged closely in the lateral direction, and a groove 3 continuous in the lateral direction is formed on the back surface of both the arranged unit pieces 1 and 2. A mosaic parquet board is formed by embedding metal wires 4 in the grooves 3.
