BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit floor in which a connecting ring is horizontally projected from two adjacent side surfaces of a rectangular floor plate, and connecting projections which can be fitted into the connecting ring are formed on the remaining two side surfaces. Regarding materials

[0002]

2. Description of the Related Art A support leg is vertically provided on the back surface of a rectangular floor plate. A connecting ring is horizontally projected from two adjacent side surfaces of the rectangular floor plate, and the remaining two side surfaces can be fitted into the connecting ring. Unit floor materials that can be connected in all directions with connection protrusions are, for example,
It is known as disclosed in Japanese Utility Model Publication No. 59-41210.

[0003]

However, in such a unit floor material, when there is a protruding portion at the ground contact portion of the support leg of the floor material, the tip of the support leg is cut off to cope with the problem. Although the material can be laid substantially horizontally, there is a problem in that it cannot be dealt with by cutting off the connecting ring when there is a protruding portion at the grounding portion of the connecting ring.

The present invention solves the above-mentioned conventional problems and provides a unit floor material which can be laid substantially horizontally even if there is a protrusion on the floor surface where the connecting ring of the floor material is provided. To aim.

[0005]

According to the unit flooring of the present invention, support legs are vertically provided on the back surface of a rectangular floor board, and connecting rings are horizontally projected from two adjacent side surfaces of the rectangular floor board. In the unit flooring material in which the connecting projections that can be fitted to the connecting ring are formed on the remaining two side surfaces, the connecting ring is provided above the bottom surface of the floor plate.

The material of the rectangular floor board used in the present invention is not particularly limited, but it is preferable that it is easy to mold and lightweight, and for example, thermoplastic synthetic resin such as high density polyethylene or polypropylene is preferably used.

The shape of the floor plate is not particularly limited, but it is preferable that it is in the form of a grid in order to reduce the amount of raw materials used, reduce the weight, and improve drainage. Further, the shape of the support leg vertically provided on the back surface of the floor plate is not particularly limited, but it is preferable to use a cylindrical shape that requires a small amount of raw material, is easy to cut, and has no strength directionality.

The size of the floor board is not particularly limited, but from the viewpoint of ease of handling during transportation and laying work, it is preferable to make a square shape with a side of about 300 mm, and the dimension in the width direction at the laying place. A groove or thin portion may be provided in parallel with the edge for easy adjustment.

To prevent slippage, the surface of the floor plate may be roughened by providing fine irregularities. Further, for reasons of aesthetics and the like, a floor material such as a square tile, a wooden brick, or a fiber reinforced cement board may be attached to the surface of the floor board.

In order to increase the stability when fitting the connecting protrusion to the connecting ring, the connecting ring protruding from two adjacent side faces of the floor plate and / or the connecting protrusion formed on the remaining two side faces. An auxiliary leg reaching the bottom surface of the floor plate may be provided at the lower end of the.

[0011]

In the present invention, since the connecting ring is provided above the bottom surface of the floor plate, even if there is a protruding portion on the floor surface of the place where the connecting ring of the floor material is provided, it can be laid substantially horizontally.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view showing a first embodiment of a unit flooring of the present invention, FIGS. 2 to 8 are perspective views showing second to eighth embodiments of a connecting ring of a unit flooring of the present invention, and FIG. It is a perspective view which shows the 2nd Example of the connection protrusion of the unit floor material of this invention.

In FIG. 1, reference numeral 1 is a floor plate made of a thermoplastic synthetic resin and having a substantially square shape in a plan view, and a base plate portion 2 thereof has three pairs of three wide rods 21 which intersect at right angles. A row of substantially square through holes 22 is formed.

Each of the through holes 22 is divided into four equal parts by a narrower cross-shaped bar 23, and the wide bar 21 is narrowed so that the width can be easily adjusted by cutting with a blade. Cross-shaped rod
An elliptical hole 24 is formed along the longitudinal direction centering on the intersection with 23. The elliptical hole 24 also has a function as a drainage hole.

On the back surface of the base plate portion 2, four corners of the through hole 22, the center points of the narrow cross-shaped rods 22, the wide cross-shaped rods 21 and the narrow cross-shaped rods are provided so as to improve water drainage after laying. At each of the intersections with the rod 22, nine cylindrical support legs 3 are hung vertically, totaling 81.

From the lower ends of the two adjacent side surfaces of the floor plate 1, a plurality of substantially square tubular connecting rings 4, 4, --- are arranged above the bottom surface of the floor plate 1 and spaced apart from each other. And a locking projection 41 having a horizontal trapezoidal cross section is provided at the upper ends of the left and right inner walls of the connecting ring 4.

A plurality of connecting protrusions 5, 5 and so on are formed on the remaining two side surfaces of the floor member 1. At the lower end of the connecting protrusion 5, substantially triangular locking claws 51 project on both sides. The floorboard 1 can be connected in four directions by fitting the connecting protrusions 5 to the connecting ring 4.

In order to increase the stability when fitting the connecting protrusion 5 to the connecting ring 4, the lower end of the connecting ring 4 is shown in FIG.
8 to 8, plate-like auxiliary legs 42 reaching the bottom surface of the floor plate 1 may be partially extended as in the second to eighth embodiments. Further, an auxiliary leg 51 reaching the bottom surface of the floor plate 1 may be provided at the lower end of the connecting protrusion 5 as in the second embodiment shown in FIG.

In the vicinity of the four corners of the through hole 22 of the substrate portion 2, a circular hole-shaped adhesive injection portion 6 is recessed so that a rectangular tile or the like (not shown) can be fixed to the upper surface of the substrate portion 2. 6
Below the inner opening, a Y-shaped perforated partition plate 61 is provided so as to increase the bonding force between the injected elastic adhesive and the floor plate.

In a portion where four or two adhesive injection parts 6 are arranged in close proximity to each other, four or two adjacent adhesive injection parts 6 are surrounded to form a substantially square-cornered shape. -Shaped or substantially rounded square peripheral wall divided into two along the side wall
62 is provided vertically so that the elastic adhesive can be collectively injected into the plurality of adhesive injection parts 6 by one operation.

[0021]

Since the present invention is constructed as described above, it is possible to lay a floor material substantially horizontally even if there is a protruding portion on the floor surface at the location where the connecting ring of the floor material is provided. I can.
