Description

[Detailed Description of the Invention] The present invention relates to a mat, and particularly to an improved mat that prevents slippage between the mat and the floor surface. More specifically, it relates to mats that mainly use synthetic resin foam sheets or carpets as the mat body, such as bath mats used in bathrooms, mats for bathing, kitchen mats, entrance mats, and leisure mats.

Conventionally, these mats tend to slip between the mat and the floor on which they are laid, and there is a risk that the mat will slip and fall when you put your feet on it in a bathroom, for example, and the floor surface cannot be easily fixed. There was a drawback that it could slide out of position. For this reason, there is an extremely high demand for mats that have an anti-slip effect, and there have been several inventions regarding mats using suction cups etc.
47435, 55-47436, 55-47437, etc.). However, these devices cannot be expected to have sufficient adhesion to the relatively small uneven surfaces of tile floors in bathrooms, etc., or they use pressure-sensitive adhesives, so they are difficult to install, and they do not last long after long-term use. There was a risk that the adhesion strength would decrease.

The present invention solves the various problems of the prior art as described above, and provides a mat that prevents slipping and movement.The gist of the invention is as follows. That is, this anti-slip mat is made by laminating a cardboard-like plastic sheet made of flexible synthetic resin and having a large number of independent convex air chambers on the underside of the mat main body with the protruding surface of the convex air chambers facing outward. DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIGS. 1 and 2 are side and back views showing one embodiment, in which 1 is a mat main body, 2 is a cardboard-like plastic sheet, and 3 is an independent convex air chamber. This embodiment is an example in which a cardboard-like plastic sheet 2 is laminated on the entire lower surface of the mat main body 1.

FIGS. 3 and 4 are side and back views showing another embodiment, in which a plurality of strip-shaped cardboard-like plastic sheets 2 are arranged in parallel and laminated on the underside of the mat main body 1. It is.
The cardboard-like plastic sheet 2 is not necessarily limited to a band-like shape, and may be a plurality of rectangular or circular shaped sheets laminated at appropriate positions.

In any of the above embodiments, the cardboard-like plastic sheet 2 is laminated against the lower surface of the mat main body 1 with the air chamber protruding surface facing outward.

The mat main body 1 of the present invention is preferably made of a synthetic resin foam sheet, but is not limited to this, and carpets such as entrance mats and joint carpets are also included. The above synthetic resin foam sheet is made of polyethylene,
The foam sheet is made of a foam such as ethylene-vinyl acetate copolymer, polypropylene, polyvinyl chloride, polyurethane, synthetic rubber, or a mixture thereof, and polyethylene foam is particularly preferred. This synthetic resin foam sheet may be a single-layer sheet, but it may also be a lamination of multiple foam sheets with different thicknesses, colors, or expansion ratios, and may also be laminated with a film or fabric on the surface. It also includes printed or embossed items. In addition, products with irregularities on the surface created using a heat molding method and those with grooves for drainage on the bottom surface are also eligible.

The cardboard-like plastic sheet 2 used in the present invention usually has a cross-sectional shape as shown in FIG. By pasting a flat sheet 4 (liner sheet) to the surface on the recess forming side to close the openings of each recess, each hollow convex portion 7 becomes an independent air chamber 3 in which air is trapped. It is of structure. It is preferable that the cardboard-like plastic sheet 2 in the present invention has a convex air chamber 3 formed on one side as shown in FIG.

The sheets 4 and 5 mentioned above are made of synthetic resins such as flexible polyethylene, ethylene-vinyl acetate copolymer, flexible polyvinyl chloride, thermoplastic elastomer, synthetic rubber, or mixtures thereof, and in particular ethylene-vinyl acetate. Copolymers are preferred. In addition, the thickness of these sheets 4 and 5 is generally
It may be about 0.1 mm to 1 mm, but is not limited to this.

This corrugated plastic sheet 2 is produced, for example, by continuously conveying the material sheet along the circumferential surface of a rotary drum type vacuum forming or pressure forming mold with a large number of depressions formed on the circumferential surface, and in the process of conveying the material sheet. By continuously vacuum or pressure forming the sheet as a molded sheet 5, and then continuously supplying and bonding the liner sheet 4 to the 5 side of the molded sheet, it is possible to continuously manufacture a long sheet. can.

Although the shape of the large number of independent convex air chambers 3 provided in the cardboard-like plastic sheet 2 is not particularly limited, a cylindrical shape is usually preferred. Although there are no particular restrictions on the diameter and height of each cylindrical shape, the preferred shape is about 3 to 15 mm in diameter and 2 to 10 mm in height.
Also, how the cylinders are arranged, the distance between adjacent cylinders,
The ratio of the area occupied by the cylinder to the total area may be arbitrary, but the preferred area ratio is about 20 to 60%.

The mat main body 1 and the corrugated plastic sheet 2 are usually laminated using an adhesive or heat fusion, but other methods such as heat fusion using an adhesive film may also be used. These two layers 1 and 2 can also be laminated continuously by further supplying the mat main body 1 to the surface of the manufactured sheet and bonding them together during the continuous manufacturing process of the above-mentioned cardboard-like plastic sheet 2.

In addition, it is also possible to provide punched holes that penetrate the entire mat, or for those that are partially laminated with cardboard-like plastic sheets 2 as shown in Figure 3, punch holes may be punched only in the mat body 1 to improve drainage. Included in this proposal.

The present invention has the above-mentioned configuration, and includes a cardboard-like plastic sheet 2 on the underside of the mat.
Use it on the floor with the side facing down. As a result, the mat does not actually slip on the floor surface, so the danger of the mat slipping and falling can be almost completely prevented, and there is no possibility that the mat will deviate from its fixed position on the floor surface.

The reason why the mat made of laminated cardboard-like plastic sheets 2 has an anti-slip effect is that the material of the cardboard-like plastic sheets 2 itself is made of a non-slip resin. Since the lower surface 6 is finished relatively thin, the lower surface 6 of each air chamber 3 due to contraction of the internal air.
This is largely related to the fact that the concave lower surface 6 of each air chamber 3 exhibits a kind of suction cup effect due to the weight of the entire mat or the pressure of stepping on the mat when it comes into contact with the floor surface. considered to be a thing.

Furthermore, when the mat of the present invention is used as a bath mat, hot water flowing between the mat and the floor flows smoothly through the spaces between the convex air chambers 3 of the cardboard-like plastic sheet 2, resulting in good drainage. Because it is breathable, any wetness between the mat and the floor will dry within a short period of time, making it highly hygienic.
