Description

  The present invention relates to a unit floor material laid on a balcony or a poolside.

  Conventionally, this type of unit flooring is provided with a male fitting portion that protrudes downward in the thickness direction from the back surface of the main body portion along two adjacent or opposite sides of the main body portion formed in a substantially rectangular shape. It is generally used that provided with a female fitting portion that receives and fits the male fitting portion in the thickness direction of the main body portion along the remaining two sides of the main body portion. The male mating portion of one unit floor material is fitted to the female mating portion of the other unit floor material and a plurality of sheets are connected to each other and laid on a balcony or the like.

However, since the unit flooring has a structure in which the male fitting part is not easily moved in the vertical direction within the female fitting part, when the laying surface has a non-land portion, a part of the unit flooring Rises from the laying surface, which is not preferable in appearance and difficult to walk.
Therefore, a bulging part is formed at the distal end of the male fitting part to serve as a detent when fitted to the female fitting part, and the female fitting is performed at the base end of the male fitting part. The unit floor material on the male fitting part side can be moved up and down relative to the unit floor material on the female fitting part side by loosely fitting to the part, so that it corresponds to the uneven part It has been proposed (see, for example, Patent Document 1).

  In addition, a bulging portion is formed at the distal end portion of the male fitting portion as a detent when fitted to the female fitting portion, and the male fitting portion is separated from the base end portion by a predetermined distance. The unit floor material on the male mating portion side and the unit floor material on the female mating portion side can be moved vertically up and down by loosely fitting the female mating portion at the position. A device that has been devised so as to be able to cope with a non-land portion has been proposed (see, for example, Patent Document 2).

However, any of the above unit floor materials can be moved up and down because one unit floor material moves up and down a predetermined distance with respect to the other unit floor material, so that it corresponds to the difference in height of the uneven area. If the difference in height of the uneven part is greater than the distance, the detent of the bulge part will not work, the male fitting part will come off the female fitting part, and the unit flooring will be connected May not be maintained.
