Description

  The present invention relates to an assembly of unit floor materials laid on a veranda, a balcony, a terrace or the like.

  For the purpose of improving aesthetics and the like, unit floor materials that are connected to each other on a balcony, veranda, terrace, etc. of a house are preferably used. However, these unit floor materials have a problem that at least the synthetic resin that forms the substrate part contracts and expands due to a temperature difference between the temperature and the temperature, the connecting part is detached and the openings are opened, or the unit floor materials are pushed up. Has occurred.

  As a means for solving the above-mentioned problems, the portion of the connecting ring where the connecting projection is inserted is formed into a long hole shape, and a play that allows the connecting projection to slide in the direction of the long hole is provided to absorb the dimensional change due to the temperature difference between cold and warm. A connection structure is disclosed (see Patent Document 1).

However, in this connection structure, the space between the unit floor materials connected to each other is not fixed because of the play, and even if it can be installed at a fixed interval at the laying site, it will eventually become a size depending on the temperature change from that state. There were problems such as inability to absorb changes.
No. 7-6320

  The object of the present invention is to provide a unit flooring that eliminates the disadvantages of the prior art and can absorb the dimensional change due to cold and warm, no matter who lays it.

  That is, the present invention is a unit flooring which has a columnar connecting projection and a connecting ring for inserting the connecting projection, and is connected to each other by fitting of the connecting projection and the connecting ring to form a floor surface. The unit floor materials that are connected to each other have play in the adjacent direction, the connection protrusion has a bulging portion for holding the fitting, and the connection ring defines the relative position with respect to the play portion and is connected It is a unit flooring characterized by having a notch for introducing a protruding portion of a protrusion.

  According to the present invention, it becomes possible to connect unit flooring materials at a fixed interval and at an interval assuming a temperature change that can occur from the environment at the time of laying. It is possible to lay unit flooring that can cope with dimensional changes. Therefore, it can prevent that a connection part remove | deviates and a mesh opening arises or unit floor materials push up.

  As a material for forming the unit flooring of the present invention, it is particularly preferable to use a synthetic resin for the substrate portion in terms of lightness, workability, cost, and the like. In addition, since the present invention can appropriately cope with a dimensional change due to a temperature change of the synthetic resin, it can be said that the present invention is particularly suitable for the synthetic resin. Examples of the synthetic resin include olefinic resins such as polyethylene and polypropylene, copolymers thereof, and thermoplastic resins such as ethylene-vinyl acetate copolymer. Furthermore, if necessary, an olefin rubber such as EPDM or EPM may be added as an elastomer as appropriate.

  In addition, it is also preferable from the viewpoint of the design property that a decorative material such as artificial lawn, ceramic tile, artificial wood and natural wood is further bonded onto the base material as a surface material. In addition, a material obtained by integrally molding a base material and a surface material with a synthetic resin is preferable in terms of light weight, handleability, cost, and the like.

  The unit flooring of the present invention has a connection protrusion and a connection ring for inserting the connection protrusion. The connecting projections and the connecting ring are fitted, and the adjacent unit floor materials are connected to each other. In FIG. 1, the unit flooring 1 has connecting projections 4 protruding in the thickness direction of the unit flooring on two adjacent sides, and connecting rings 5 on the remaining two adjacent sides. By fitting the connecting protrusion 4 and the connecting ring 5, a plurality of unit floor materials can be connected to form a floor surface.

  Further, as the shape of the unit flooring, in addition to the rectangle as shown in FIG. 1, a triangle, a polygon, or a combination thereof is also preferable in terms of design.

  The shape of the connecting protrusion may be a columnar shape or a prismatic shape, and may be a hollow structure having a cavity inside the protrusion or a solid structure.

  Moreover, as for the unit flooring of this invention, the said connection protrusion has a bulging part. The bulging portion can hold the fitting with the connecting ring. The connection protrusion 4 as shown in FIG. 2 (A) has a bulging portion 6, and when connected to the connection ring 5 as shown in FIGS. 2 (B) and 2 (C), the bulging portion 6 returns. It has a structure that stops and is difficult to come off. As the shape of the bulging portion, it is preferable to taper from the viewpoint of easy attachment / detachment.

  It is important that the unit flooring of the present invention has play in the direction in which the unit flooring members connected by the connecting rings are adjacent to each other. For example, as shown in FIG. 3, when the temperature of the initial flooring state (A) drops in winter and the material constituting the unit flooring contracts, the connecting projection 4 slides to absorb the dimensional change as shown in (B). . Further, when the temperature rises in summer and the material constituting the unit flooring expands, the connecting protrusion 4 slides to absorb the dimensional change as shown in (C).

  In the unit flooring of the present invention, it is important that the connecting ring has a notch. The notch defines a relative position with respect to the play portion in the connection ring and introduces the bulging portion of the connection protrusion.

  The relative position of the notch with respect to the play portion in the connection ring is preferably approximately the center of a hole formed by the connection ring (hereinafter also referred to as a connection hole). By providing a notch at this position, it is possible to flexibly cope with temperature changes starting from the initial environment (FIG. 3A) regardless of the season in which the unit flooring is laid (FIG. 3B). ), (C)).

  As the shape of the cutout portion, a tapered portion 8 directed toward the center line side of the connecting hole 7 as shown in FIG. 2 (B) may be used, or a cutout portion vertically cut out as shown in FIG. 2 (C). 9 is also acceptable. Further, the shape of the cutout portion viewed from above may be polygonal or circular, but it is preferable to match the cross-sectional shape of the connecting protrusion. In addition, [width including the bulging portion 6 of the connecting protrusion 4]> [width not including the notched portion of the connecting hole 7] makes it easy to guide the connecting protrusion 4 by the notched portion, and fits. It is preferable from the point of making it difficult to remove the joint. Furthermore, [the width not including the bulging portion 6 of the connecting protrusion 4] ≧ [the width not including the notch of the connecting hole 7] is to prevent a small impact when laying after being guided and introduced. It is preferable because it is difficult to move.

One Example of the unit flooring of this invention is shown, (A) is a top view, (B) (C) is sectional drawing. It is an expansion perspective view which shows the principal part of the unit flooring of this invention, (A) shows a connection protrusion, (B) (C) shows a connection ring. It is sectional drawing which shows the effect | action of the unit flooring of this invention, (A) is the connection initial stage, (B) is in the contracted state, (C) shows the expanded state.
