Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a floor mat, and more particularly, to a floor mat in which a rubber plate or the like is integrally bonded to the back surface of a fiber portion by thermocompression bonding.

(Prior art) Conventionally, this type of floor mat has been manufactured by integrally providing a natural or synthetic elastomer on the back side of a fiber portion (carpet) formed into a desired size, and when bonding the two by thermocompression, the fiber portion is In order to prevent warping toward the elastomer side, which has a high shrinkage rate, the shrinkage rate of the elastomer was suppressed by containing a desired amount of short fibers of a desired length in the elastomer (for example, Utility Model Publication No. 48-92723). issue).

(Problem to be solved by the invention) However, since the above-mentioned conventional floor mats contained short fibers throughout the elastomer, they had the problem of high cost, and the fluidity of the elastomer was impaired, causing the fibers to There was a risk that the crimping properties with the parts would be impaired.

In addition, by including short fibers throughout the elastomer, the elastomer becomes hard as a whole, and the cushioning properties of the floor mat tend to be impaired.

The present invention was devised in view of the above-mentioned problems of the prior art, and its purpose is to inject short fibers only inside the periphery of the rubber plate, etc., excluding the crimped area with the fiber part. To include,
To reduce the shrinkage rate of a rubber plate, etc., while reducing costs, and to maintain cushioning properties as a floor mat without impairing the adhesion between the fiber part and the rubber plate, etc.

(Means for Solving the Problem) The technical means achieved by the present invention to achieve the above object is to attach a rubber plate or soft synthetic resin to the back side of the fiber part formed to a desired size from synthetic fiber material. In a floor mat formed by integrally providing a board, the fiber portion is thermocompression bonded to the surface of the rubber board, etc., leaving a peripheral edge in a predetermined area, and short fibers are included in the peripheral edge of the rubber board, etc. That's true.

(Function) Due to the above-mentioned technical means, short fibers are not contained inside the rubber plate below the fiber portion, and the fluidity of the rubber etc. during thermocompression bonding is good.

The peripheral edge of the rubber plate or the like is positioned around the fiber portion in a brim-like manner, and the contraction rate of the peripheral edge is suppressed by the short fibers contained inside, thereby suppressing warping of the entire rubber plate.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

A in the figure is a floor mat, and the floor mat A is the fiber part 2.
A plate body 1 made of a rubber material or the like and formed larger than the fiber part 2 is integrally bonded to the back surface of the fiber part 2 by thermocompression, excluding the crimped part of the fiber part 2. Short fibers 3 are contained only within the periphery of the body 1.

The plate body 1 is composed of, for example, a flat plate-shaped crimped part 1a and a peripheral part 1b including short fibers 3. It is formed by press-curing raw rubber (such as raw rubber mixed with ordinary additives such as rubber) and cutting it into a rectangular shape of a desired size.

The peripheral edge part 1b is made of, for example, raw rubber similar to the crimp part 1a mixed with short fibers 3 such as nylon, and has an overall rectangular shape of approximately the same size as the crimp part 1a, with a hollow part 1b' in the center thereof. It is formed into a plate having a shape and press vulcanized.

The amount of short fibers 3 included in the peripheral portion 1b is an appropriate amount relative to the raw rubber.

Further, the plate body 1 is not limited to a rubber material, and may be made of a soft synthetic resin material such as polyvinyl chloride or polyurethane.

Next, the fiber section 2 is based on a nonwoven fabric of a desired size made of synthetic fibers such as nylon, and is formed into a rectangular shape that is slightly larger than the hollow section 1b' of the peripheral edge section 1b.

The fiber portion 2 is not limited to nylon, and may be made of tetron or other desired synthetic fibers.

Then, the peripheral edge part 1b and the fiber part 2 are placed above the crimp part 1a so that the fiber part 2 is positioned on the crimp part 1a, and then they are thermocompressed to form the crimp part 1a,
The peripheral edge portion 1b and the fiber portion 2 are joined and integrally formed.

Further, as shown in FIG. 3, the hollow portion 1 of the peripheral portion 1b
A plate body 1 formed by fitting a crimp part 1a onto b' and press vulcanizing the plate body 1, and a fiber part 2 placed only on the crimp part 1a of the plate body 1 are bonded together by thermocompression. Good too.

In this embodiment, the floor mat A has been described as having a rectangular shape, but it may have a desired shape such as a round shape or a polygonal shape.

In addition, in this embodiment, the short fibers 3 are
Plate body 1 formed by thermocompression bonding of rubber material dispersed throughout b and a compression bonding portion 1a made only of ordinary rubber material.
However, as long as the peripheral edge of the plate 1 (the part where the fiber part is not provided) contains short fibers or a short fiber layer, it may have any configuration. do not have.

(Effect of the invention) Since the present invention has the above-mentioned configuration, the shrinkage rate of the peripheral edge of the rubber plate etc. located in a brim shape around the fiber part is suppressed, and the shrinkage rate of the peripheral edge with the suppressed shrinkage rate is reduced. It is possible to suppress warpage of the entire rubber plate.

Therefore, short fibers need only be included in the periphery of the rubber plate instead of the entire rubber plate as in the past, reducing costs and reducing the shrinkage rate of the rubber plate, resulting in products with less warping. High-value floor mats can be provided at low prices.

In addition, since short fibers are not contained inside the crimped portion of the rubber plate below the fiber portion, which is crimped with the fiber portion,
The fluidity of the rubber etc. is good during thermocompression bonding, and there is no risk of impairing the adhesion with the fiber part.Furthermore, the short fibers are only included in the periphery, and the other parts are simply rubber materials, etc., so the floor The cushioning properties of the mat as a whole can also be maintained.
