Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin roll-up floor material of a type in which floor materials formed to have a constant length are lined up and laid on a floor surface, and a method for manufacturing the same.

[0002]

2. Description of the Related Art In order to prevent slipping at poolsides, to reduce the danger of slipping and falling down, and to make it possible to walk with bare feet without high temperatures in summer. Resin flooring is often laid. Resin flooring is characterized in that its hardness is lower than that of mortar and the like, and that it is less likely to reach high temperatures than that of inorganic surface materials.

[0003] Also, in the summer, it is used as a tennis court,
If the site is to be used for multiple purposes, such as being used as a parking lot around a ski area in winter, resin flooring that can be used for tennis will be laid in summer and removed in winter. In other words, flooring is repeatedly laid and removed every season.

Conventionally, such a flooring material has a side of 30 pieces.
A floor member formed in a square shape of about cm has been used. That is, when laying, the floor members are laid one by one from the corners, and when the floor members are removed, they are removed one by one from the corners (for example, see Japanese Utility Model Publication No. Sho 62-36911).

[0005]

As described above, in the conventional floor coverings, the floor members are laid one by one from the corners or removed one by one from the corners regardless of whether they are laid or removed. However, there is a problem that the installation work and the removal work are complicated and time-consuming because it is necessary to proceed.

The present invention was devised to solve the above problems, and an object of the present invention is to provide a roll-up type flooring which facilitates the laying work and the removing work, and a manufacturing method thereof.

[0007]

In order to solve the above-mentioned problems, the roll-up type flooring material according to claim 1 of the present invention has a rectangular shape in a plan view, and one of the long side surfaces along the longitudinal direction thereof. A plurality of floor members are provided in the width direction in which engaging projections are formed at both ends in the width direction, and engaging holes are formed at both ends in the width direction of the other long side surface along the longitudinal direction. , The adjacent floor members are connected to each other by engaging the engaging projections of one floor member with the engaging holes of the other floor member and connecting the adjacent floor members with the engaging projections as rotation axes. Is a roll-up type floor material configured to be sequentially wound,
The opposing side surfaces on the upper surface side of the engaging protrusions and the engaging holes of the adjacent floor members are formed as inclined surfaces that gradually expand toward the upper surface side of the rotating shaft.

As a result, when the floor member is successively wound around the rotation axis from the end, the end floor member and the second floor member adjacent to the end member come into contact with each other until the opposing inclined surfaces come into contact with each other. The member is rolled up and then the end floor member and the second floor member are rolled up until the opposing slopes of the second floor member and the adjacent third floor member meet. In this way, the third floor member and the fourth floor member are sequentially wound up, and finally the floor member at the opposite end is wound up.

That is, up to the first winding, the relative positional relationship between the adjacent floor members is determined by the contact between the adjacent inclined surfaces, and from the second winding, the polygon formed by the first winding. The floor member will be sequentially wound along the outside of the shaped floor member (i.e. without hitting adjacent slopes).

Further, when the roll-up type flooring material is laid on the floor surface, it is necessary to be in a state conforming to the shape of the floor surface.
In this case, in the roll-up type flooring material of the present invention, the flooring material is recessed along the concave portion of the floor surface until the adjacent inclined surfaces hit each other.

According to a second aspect of the present invention, there is provided a take-up floor material according to the first aspect, which is lower than the engaging projections and the engaging holes of the adjacent floor members. A predetermined gap is formed between the opposite side surfaces of the.

As a result, when the roll-up type flooring material is laid on the floor surface and the floor surface is convex, the floor surface is covered until the lower end edges of the side surfaces of the adjacent floor members hit each other. The floor material will protrude along the convex portion.

According to a third aspect of the present invention, in the method for manufacturing a roll-up type flooring material, the plan view has a rectangular shape, and the long side surfaces along one of the longitudinal directions of the winding floor material are engaged with each other at both ends in the width direction. A mating protrusion is formed, and a plurality of floor members each having an engaging hole formed at both widthwise end portions of the other long side surface along the longitudinal direction are arranged in the width direction, and adjacent floor members are adjacent to each other. The engaging projections of one floor member are locked and connected to the engaging holes of the other floor member so that the connected floor members can be sequentially wound around the engaging projections as a rotation axis. A method for manufacturing a roll-up type floor material, which is adapted to the shape above the center of the engaging projections of the connected floor members, and has an inner surface shape excluding the engaging projections and the engaging holes. And the upper mold formed on the lower part of the floor member connected below the center of the engaging protrusion. And a lower die formed into an inner surface shape excluding the engaging protrusion and the engaging hole portion, and a cylindrical peripheral surface of which has a tip end peripheral surface in the shape of the engaging hole. A shaft die having a fitting tapered surface and an engaging recess formed at the center of the tip end surface that fits the shape of the engaging projection is provided, and the upper die and the lower die are provided. Insert the tip of the metal mold from the side into the cut-out portion for joining and forming the engaging projection and the engaging hole, and in this state, fill the resin into the metal mold, and then insert the metal mold into the metal mold. Is laterally pulled out, and then the upper die and the lower die are opened to form the floor member in the connected state.

That is, it is possible to form each floor member in a state in which the floor members can be wound and connected by one-time molding, and the trouble of sequentially connecting the individually molded floor members can be saved. It is a thing.

Are formed on the inclined surfaces 2a and 5a that gradually expand from the engagement protrusions 4 and 4 toward the upper surface 9 side, and the adjacent floor members 1 and 1 are
A predetermined gap P is formed between the engaging projections 4, 4 and the facing side surfaces 2, 5 below the engaging holes 7, 7. Thus, the connected floor members 1, 1,... Can be sequentially wound inward with the engagement protrusions 4, 4 as rotation axes.

That is, when the floor members 1, 1 ... Are sequentially wound from the ends around the engaging projections 4, 4, the first floor member 1 (indicated by reference numeral 1a in FIG. 7) and the adjacent floor member 1 are provided. The first floor member 1a is wound up and then the second floor member 1b is wound until the opposing inclined surfaces 2a, 5a of the second floor member 1 (shown by reference numeral 1b in FIG. 7) hit each other. The first floor member 1a and the second floor member 1 until the opposing inclined surfaces 2a, 5a of the third floor member 1 (shown by reference numeral 1c in FIG. 7) adjacent thereto hit each other.

floor members 1f to 1j are sequentially wound up without hitting a and 5a).

In this embodiment, the inclined surfaces 2a and 5a are
The inclination angle is 30 degrees, and thus the wound shape is hexagonal as shown in FIG. If the inclination angles of the inclined surfaces 2a and 5a are 45 degrees, the wound shape will be a square shape. The inclination angles of the inclined surfaces 2a and 5a may be arbitrarily determined in consideration of such a shape at the time of winding.

Further, when such a roll-up type floor material A is laid on the floor surface, it must be in a state conforming to the shape of the floor surface. In this case, when the floor surface is recessed, the floor members 1, 1 are recessed along the recesses until the adjacent inclined surfaces 2a, 5a hit each other. Further, when the floor surface is convex, the locking projections 4 of the adjacent floor members 1, 1 are
Since the predetermined gap P is formed between the facing side surfaces 2 and 5 below 4, the floor members 1 and 1 are arranged along the convex portion until the lower end edges 2b and 5b of the facing side surfaces hit each other. It will stick out.

Each floor member 1, 1 ... Has an L-shaped projection 15 formed on the lower end edge of one short side surface 12 along the width direction, and the lower end edge of the other short side surface 13 partially forms. A fitting concave portion 14 is formed by being cut out so that the L-shaped projection 15 can be fitted therein. That is, a plurality of roll-up floor materials A of the present invention are arranged in the width direction, and L formed on the short side surface 12 of each floor member 1, 1 ... Character projection 15
To each of the floor members 1, 1
By fitting the fitting recesses 14 formed on the short side surfaces 13 of the ..., the roll-up floor material A can be sequentially connected in the width direction.

However, the connecting structure is not limited to this, and for example, one short side surface 12 is cut upward by a predetermined length from two locations on the lower edge so as to replace the L-shaped projection 15 with a constant width. -Shaped protrusions (not shown) are formed, and on the other short side surface 13, a protrusion holding portion having a U-shaped cross-section that allows the notch-shaped protrusions to be inserted from above is formed in a protrusion shape (not shown). The floor members 1, 1 ... of the roll-up floor material A adjacent to the protrusion holding portion formed on the short side surface 13 of the floor members 1, 1. By fitting the notch-shaped projections formed on the short side surface 12 of the above, the roll-up flooring material A may be structured so as to be sequentially connectable in the width direction.

With this structure, the notch-shaped protrusions are flush with the short side surface 12, so that there is little concern that the notch-shaped protrusions may hit something during transportation, winding, or unfolding. Further, the protrusion holding portion is formed on the short side surface 13 in a protruding shape, and the shape thereof is a U-shaped cross section, which is a shape capable of obtaining sufficient strength. Therefore, there is almost no fear that the projection holding portion will hit against something and break during transportation, winding, or unfolding.

When the take-up floor material A is connected in the longitudinal direction, as shown in FIG. 8, the floor member 1 at one end of the next take-up floor material A is slightly curved with both hands. Then, the engaging protrusions 4 and 4 may be bent inward and fitted into the engaging holes 7 and 7 of the last floor member 1 of the take-up floor material A to be connected. Although the floor member 1 is formed of a hard resin, the shape thereof is relatively easy to bend with a downward U-shaped cross section, so that the floor member 1 can be curved to this extent.

The size of the floor member 1 is L = 5 in the longitudinal direction.
The width is about 0 to 70 cm, the width direction W is about 5 to 10 cm, and the number of the connected pieces may be arbitrarily determined according to the place of use.
