[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor finishing material. More specifically, it relates to a floor finishing material suitable for a free access floor and the like.

[0002]

2. Description of the Related Art Conventionally, floor finishing materials have been fixed with an adhesive or nails. Recently, however, a removable structure such as a free access floor or a multipurpose floor has been required. Carpets. Tile carpets are widely used as floor finishing materials that can be laid, because the surface of the tile carpet is flexible and there is little lifting or curling.

On the other hand, floor finishing materials made of rigid materials such as wood, hard resin, tiles, and stones are difficult to lay like tile carpets because they warp or float around four sides. In addition, male and female fittings are provided in order to prevent the four rounds from being lifted, but it is difficult to remove them partially because they are restricted.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a floor finishing material whose surface is made of a rigid body and which can be detachably laid. "0005"

According to the invention of the present application, the specific gravity is appropriately adjusted on the lower layer (2) made of a flexible sheet as a base layer (31) mainly composed of a flexible resin or rubber. An upper layer (4) made of a rigid decorative material is laminated via an intermediate layer (3), and a fruit (6) is provided on two opposite sides of the laminate (5), and the upper layer (4) And the intermediate layer (3)
At least one parting line (7) that can be split in parallel along (6)
Floor finishing material (1) "provided with at least one book is provided.

The flexible sheet (21) constituting the lower layer (2) is
Any material may be used as long as it is a flexible sheet-like material. Examples of the material include resin, foamed resin, paper,
Woven fabrics, nonwoven fabrics, metals and the like can be mentioned. The shape may be any as long as it can function as a sheet material. For example, the shape may be configured as a net-like sheet material.

[0007] The intermediate layer (3) is a layer that contributes to floor adaptability and weight adjustment of the floor covering material of the present application, and is formed of a flexible resin or rubber as a base layer (31). The specific gravity of the intermediate layer (3) is adjusted to about 0.8 to 1.5, preferably about 1.0 to 1.5. That is, when the specific gravity of the upper layer (4) described later is 0.7 or less, it contributes to stabilization as a weight to the upper layer (4), and when the specific gravity of the upper layer (4) is 1.5 or more, it contributes to weight reduction. The adjustment of the specific gravity is performed by mixing an appropriate heavy material into the base layer (31). Examples of the flexible resin or rubber that constitutes the base layer (31) include synthetic resins and synthetic rubbers such as vinyl chloride, polyethylene, polypropylene, and urethane resins, and materials recycled from these wastes. In addition, as the heavy material, inorganic materials such as tantalum, talc, diatomaceous earth, carbon black, metal powder, and metal oxide powder are preferably used, but an organic material having a relatively high specific gravity can also be used in some cases. .

The rigid decorative material constituting the upper layer (4) includes:
Wood materials such as natural wood decorative plywood, vinyl chloride and acrylic,
Hard resins, artificial marbles, tiles, stones, and the like, in which an inorganic filler is mixed into a polyester resin or the like, may be used. Further, the upper layer (4) may be formed by arranging the above-mentioned materials in a strip shape or a tile shape. Such a configuration is preferable because even if there is a warp, the floating is not conspicuous.

The above-mentioned lower layer (2), intermediate layer (3) and upper layer (4)
Are laminated via a suitable adhesive, but when the intermediate layer (3) itself has tackiness, the intermediate layer (3) does not need to use a separate adhesive. The obtained laminated body (5) is provided with connecting fruits (6) composed of a combination of male and female shapes capable of repeatedly connecting the laminated body (5) only on two opposing sides. When the laminate (5) is formed in a rectangular shape, two sets of two opposing sides are obtained. However, only one of the sets may be provided with the fruit (6). They may be provided together.

In the laminate (5), the upper layer (4) and the intermediate layer (3) have one dividing line (7) which can be divided in parallel along the fruit (6).
More than books are provided. That is, the intermediate layer (3) and the upper layer (4) divided by the dividing line (7) are held without being completely divided by the lower layer (2) provided on the lower surface of the intermediate layer (3). In other words, the lower layer (2) in the parting line (7) acts as a hinge, and the laminated body (4) can be bent at this part. A plurality of the dividing lines (7) may be provided at appropriate intervals as long as they are parallel to the actual (6). Further, a dividing line (8) orthogonal to these dividing lines (7) may be provided. As described above, the more the dividing lines (7) and (8) are provided, the more the familiarity of the laminate (5) increases.

[0011]

According to the present invention, a lower layer made of a flexible sheet is provided.
(2) A laminate (5) in which an upper layer (4) made of a rigid decorative material is laminated via an intermediate layer (3) whose specific gravity is appropriately adjusted as a flexible resin or rubber as a base layer (31). The floor finishing material (1) is provided with bonding nuts (6) on two opposite sides thereof, and the upper layer (4) and the intermediate layer (3) are paralleled along the fruits (6). Since at least one parting line (7) that can be divided into two parts is provided, even if the floor finishing materials (1) are connected to each other via a real (6), Since the lower layer (2) remaining undivided in the section (7) acts as a hinge because of its flexibility, the floor covering (1) can be bent along the dividing line (7), The coupling can be released and removed.
