Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an elastic tile, and in particular to an elastic tile in which an elastic surface material is attached to the surface of a substrate, and in which the elastic surface material can be freely attached and removed. Regarding.

[Prior art] Elastic tiles, which are made by attaching an elastic surface material made of rubber or a compound thereof to the surface of a substrate made of a highly rigid material such as cement, have traditionally been used as paving materials for sidewalks, parks, etc. ■ It feels good when walking and has a soft feel on the legs and hips.

■ Colors can be freely selected and the appearance is excellent.

■ Noise caused by walking is reduced.

The following effects are expected.

Conventionally, as an elastic tile, Utility Model Application No. 56-138902
, Utility Model Publication No. 62-89302, etc. have been proposed, but all of these are manufactured by preparing a rubber surface material in advance, pouring cement onto the back side of this surface material, and hardening it.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional elastic tiles, the rubber surface material and the cement substrate are fixed together, so when the rubber surface material is worn or damaged,
It is not possible to replace only the facing material, the entire elastic tile must be replaced.

An object of the present invention is to solve the above-mentioned conventional problems and provide an elastic tile whose surface material can be easily attached and detached.

[Means for Solving the Problems] The elastic tile of the present invention is such that an elastic surface material having grooves on the back side is removably attached to a substrate having protrusions on the surface by fitting the protrusions with the grooves. Resilient tiles installed. The cross-sectional shape of the protruding strip perpendicular to the length direction has a tapered top and a constricted base.

In addition, in the present invention, the materials constituting the substrate include:
It is preferable to use materials that have sufficient rigidity and elasticity to prevent damage to the fitting part, and are generally made of concrete, asphalt concrete, or synthetic resins such as polyethylene, polypropylene, vinyl chloride, polystyrene, ABS, etc., composites, or foamed materials. One example is the body. The substrate does not necessarily have to be a solid plate, and may be one with ribs left to form a space as long as it is within the allowable range of mechanical strength.

In addition, the base polymer of the material constituting the elastic surface material varies depending on its color, and black or brown colors include natural rubber (
NR), styrene butadiene rubber (SBR), chloroprene rubber (CR), ethylene propylene rubber (EPR)
, butyl rubber, butadiene rubber (BR), and other general-purpose polymers can be used alone or in a blend of two or more. In addition, fibrous rubber chips obtained by vulcanization and curing with a binder such as a general-purpose rubber or urethane can also be used. EPR for light color.

Hypalon, chlorinated polyethylene, halogenated EPR,
Butyl rubber, halogenated butyl rubber, etc. can be used alone or in combination of two or more. others,
Coloring can also be achieved by vulcanizing and curing fibrous rubber chips with a colored binder.

The polymer constituting the elastic surface material contains various commonly used f! Additives can be used in combination. In particular, it is extremely effective to use a flame retardant as a flame retardant method when flame retardancy is required. As a flame retardant, use an inorganic flame retardant such as aluminum hydroxide in an amount of 10 to 1 part by weight per 100 parts by weight of the polymer.
00 parts by weight is preferable, and it is also effective to use highly flame-retardant polymers such as CR, chlorinated polyethylene, and halogenated EPR.

Furthermore, in order to reduce costs, it is possible to add plasticizers, etc., but in terms of the dimensional stability of the resulting elastic surface material, especially the recesses on the back side, the amount of such low boiling point plasticizers and softeners to be added is limited. It is important to limit this to the minimum necessary.

In addition, since light-colored compounding polymers and polymers with high weather resistance and flame retardancy are generally expensive, these polymers are used only in the surface layer of the elastic surface material, and the lower layer is a two-layer structure in which regular polymers are used. By adopting this structure, it is possible to reduce the total cost without impairing the color scheme, weather resistance, or flame retardancy. Further, cost reduction can also be achieved by foaming part or all of the polymer.

In the present invention, the physical properties of the elastic surface material are hardness JIS
A is 50 to 80 degrees, especially 60 to 70 degrees, and elongation is 5
0% or more, especially 100% or more, and the tear strength is 10 K g f / cm or more, especially 20 K
It is desirable that it is greater than or equal to g f / cm.

Such an elastic tile of the present invention can be easily manufactured by molding the substrate and the elastic surface material into desired shapes, and then fitting them together using the protrusions and grooves.

[Function] In the elastic tile of the present invention, the substrate and the elastic surface material are removably fitted together through the protrusions and grooves, and only the surface material can be replaced. Moreover, since the top of the protrusion is tapered, the protrusion can be easily fitted into the groove. In addition, since the base portion is constricted, the fitting state between the protrusion and the groove can be stabilized.

A total of 6 pieces are installed in parallel.

In the present invention, the cross-sectional shapes of the protrusions formed on the substrate are not limited to those shown in FIGS. 1 to 4. For example, a hexagonal shape 4A having a neck 4a as shown in FIG. 5, a circular cross-sectional shape 4B as shown in FIG.
The convex strip may have a fan-shaped shape 4F as shown in the figure, or a shape such as 4C, 4E, 4G, etc. each having a neck 4a as shown in FIGS. 7, 9, and 11. The cross-sectional shape may be tapered at the top and constricted at the base, and various other shapes may be adopted.

Moreover, it is also possible to employ a combination of protrusions of different shapes.

Further, there is no restriction on the installation form of the protruding strips 4 on the substrate 3, and as shown in FIG. 12, the substrate 3A (see FIGS.
The embodiment shown in FIG. 4 corresponds to this pattern), the substrates 3B are arranged perpendicularly as shown in FIG. 13, the substrates 3C are arranged diagonally orthogonally as shown in FIG. Various configurations may be adopted, such as a substrate 3D arranged diagonally in parallel as shown in FIG. 16, a substrate 3F arranged concentrically as shown in FIG. 17, etc. Moreover, a combination of these patterns can also be employed.

In addition, in the present invention, in order to prevent the edges of the elastic surface material from turning over, a protrusion having a shape with a bulged middle part in the protruding direction as shown in FIG. 18 is provided near the edge or corner of the substrate 3. 7 is provided, and the elastic surface material is also provided with a recess (
(not shown) may be formed, and these protrusions 7 and recesses may be fitted into each other.

[Effects of the Invention] As detailed above, in the elastic tile of the present invention, only the surface material can be attached and detached. Therefore, in the elastic tile of the present invention, when the elastic surface material is worn out or damaged, only the elastic surface material can be easily replaced, which is extremely advantageous in terms of maintenance, cost, etc.

In addition, since the fitting portion between the elastic surface material and the substrate extends as a convex strip and a groove, the stability of the bond between the elastic surface material and the substrate is good.Moreover, the cross-sectional shape of the convex strip has a tapered top. Because it is tapered into a shape, the protrusions can be easily fitted into the grooves, and the constricted base makes it possible to increase the bonding strength between the protrusions and the grooves. Take.
