Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combination tile having excellent performance and handleability.

[0002]

[Prior art]

 As a method of laying tiles on the floor surface, etc., in addition to the method of tightly arranging the tiles while fixing them with an adhesive, the method of using various combined tiles such as press fitting by combining pin-shaped protrusions and holes is adopted. Has been done.

[0003]

[Problems to be solved by the device]

 Although the method of arranging tiles closely while fixing them with an adhesive is a widely adopted method, it is not suitable for the purpose of temporary tiles for exhibition halls and workshops.

A small notch-shaped rectangular recess (3 y) is provided from the center to the lower part of the end face at a nearby position, and the trapezoidal projection ((y) is formed on the lower half of the end face at the center of side c, side d or near the center. The reverse taper trapezoidal recess (2y) that fits 2x) is provided, and the lower part that fits into the rectangular recess (3y) is located from the center to the bottom of the end face at a position at least near both sides of side c and side d. It has a structure with a small wedge-shaped protrusion (3x) with a sharp side.

The present invention will be described in detail below.

The combination tile of the present invention comprises a plastic tile having a rectangular shape such as a square or a rectangle. This tile is manufactured by injection molding a resin raw material containing auxiliary materials such as a filler, a flame retardant, and a colorant as required.

The surface of the tile main body (1) may be a smooth surface, a non-slip surface, a patterned surface, or the like.

It is desirable to provide ribs (4) on the back surface of the tile body (1) along at least four circumferences thereof, and it is desirable to provide ribs (4) other than the four circumferences. Further, the lower surface of the tile rib (4) may be formed as a non-slip surface, or a cushioning material may be provided on the rear surface of the tile body (1).

In the present invention, when the pair of adjacent two sides of the tile body (1) are a and b and the other pair of adjacent two sides is c and d, first, the center of the side a and the side b Or, on the lower half side of the end face at the position near the center, an inverse taper trapezoidal protrusion (2x) protruding from the tile body (1) is provided. The number of trapezoidal protrusions (2x) is one or more per side.

Then, a small notch-shaped rectangular recess (3y) is provided from the central portion to the lower portion of the end face at a position near at least both sides of the sides a and b. The number of the rectangular recesses (3y) is 2 or 3 or more per side.

Further, a reverse taper trapezoidal recess (2y) into which the trapezoidal protrusion (2x) is fitted is provided on the lower half side of the end face at the center of the side c or the side d or at a position near the center. The number of the trapezoidal recesses (2y) is the same as the number of the trapezoidal protrusions (2x) described above.

Further, a small wedge-shaped projection (3x) having a sharp lower end that fits into the rectangular recess (3y) is provided from the central portion to the lower portion of the end face at a position at least near both sides of the sides c and d. The number of the wedge-shaped protrusions (3x) is the same as the number of the rectangular recesses (4) described above.

The combination tile of the present invention having the above structure is useful as a tile provided on a floor surface of an exhibition hall, a passageway, a workshop, a warehouse, or the like.

[0016]

[Action]

 In the combination tile of the present invention, a pair of adjacent two sides a and b of the tile body (1) are trapezoidal protrusions (2x) of reverse taper shape and small square recesses of cut shape. Both sides (3y) are provided, and another pair of two adjacent sides, c and d, have a trapezoidal recess (2y) with an inverse taper shape and a small wedge-shaped protrusion (3x) with a sharp lower side. Both are set up.

After aligning the trapezoidal protrusions (2x) of one tile with the trapezoidal recesses (2y) of the other tile so that they overlap each other, the latter tile is pushed downward and the former tile is pushed. The wedge-shaped projections (3x) of the latter tile fit into the rectangular recesses (3y) of the two tiles, and both tiles are connected. If one of the two tiles is lifted in the connected state, both tiles will remain connected. In this way tiles can be connected one after the other in either direction. When removing it, it is sufficient to bend it in a “F” shape when viewed from the front so that the connecting end face portions of both tiles are convex upward.

If the size of the trapezoidal protrusion (2x) is slightly smaller than the size of the trapezoidal recess (2y), and the size of the wedge-shaped protrusion (3x) is slightly smaller than the size of the rectangular recess (3y), Since there is a small gap between the tiles after connection, even if the tile may expand due to sunlight after installation on the floor surface, etc., the expansion is absorbed by the gap and floats on the installed tile. Will never occur.
