Description

[Detailed description of the invention] The present invention relates to the improvement of slats that are used by laying them on the floor of a bathroom, etc., and in particular, two anti-slip bodies made of internally plasticized vinyl chloride resin are installed on the lower surface of the pedestal that supports the top plate. This invention relates to slats that are integrally molded by color extrusion molding and exhibit a stable anti-slip effect over a long period of time.

Synthetic resin grates made of polystyrene foam have recently been widely used because of their advantages of being lightweight, water resistant, and having a cushioning effect.

However, if this product is used on a slippery surface such as a bathroom floor, it has the drawback that accidents such as slips and falls are likely to occur due to the surface slipperiness of polystyrene foam. Therefore, a structure has been proposed in which a pedestal made of polystyrene foam that supports the top plate is extruded and then foamed rubber is bonded to the lower surface of the pedestal using an adhesive to prevent slipping.

However, this method using foamed rubber not only does not provide a sufficient anti-slip effect, but also has the disadvantage that the adhesive layer is destroyed by the constantly humid operating environment, and the anti-slip body peels off shortly after use.

The present invention eliminates the above-mentioned disadvantages of conventional slats, and the lower surface of the pedestal that supports the upper plate is made of internally plasticized vinyl chloride resin that maintains high adhesiveness on the surface by itself without the use of external plasticizer. The object of the present invention is to provide a gridiron in which the anti-slip body is integrally molded by two-color extrusion molding so that a stable anti-slip effect can be obtained over a long period of time.

To explain the present invention in detail, in a gridiron grid, a plurality of upper plates having an appropriate width are connected and fixed in parallel to the upper surface of the base legs arranged at appropriate intervals so as to be orthogonal to the base legs. The base leg is formed by two-color extrusion molding of a base base body made of polystyrene foam and a non-slip body made of internally plasticized vinyl chloride resin, so that the head of the non-slip body is embedded within the base body, and the lower part thereof is This is a drainboard characterized by being integrally molded so as to protrude from the lower surface of the base body.

EMBODIMENT OF THE INVENTION Hereinafter, the specific structure of this invention will be explained in detail based on the illustrated Example.

In the figure, 1 is an upper plate made of synthetic resin such as polystyrene foam having an appropriate length and width, and 2 are arranged at appropriate intervals on the lower surface of this upper plate 1 in a direction perpendicular to the upper plate 2. It is a fixed pedestal.

The base leg 2 consists of a base base body 3 made of polystyrene foam and a non-slip body 4 made of internally plasticized vinyl chloride resin located below this base base body 3. Reference numeral 4 is a two-color extrusion molding in which the head 5 of the anti-slip body 4 is embedded in the base body 3, and the lower part thereof is simultaneously extruded so as to protrude from the lower surface of the base body 3.

Incidentally, a groove 6 for collecting adhesive when bonding the upper plate 1 is formed in the upper surface of the base plate body 3.

In this way, the head 5 of the anti-slip body 4 is embedded in the base plate body 3, so there is no need to use adhesive as in the conventional case, and the head 5 is buried in the base plate body 3. It has a structure that is held in place so it is extremely sturdy.

The internally plasticized vinyl chloride resin forming the anti-slip body 4 is made by adding a higher alkyl vinyl derivative such as lauryl vinyl ether during the polymerization of vinyl chloride and copolymerizing it together. The molecule has long alkyl groups as side chains in some places, and these alkyl groups act similar to an external plasticizer, weakening the bonds between copolymer molecules, resulting in extremely flexible and highly adhesive surfaces. This is what makes it special.

The present invention focuses on such characteristics of internally plasticized vinyl chloride resin, and is integrally fixed to the lower surface of the base plate body 3 by two-color extrusion molding, and does not contain a large amount of external plasticizer. Unlike anti-slip materials, there is no migration of plasticizer, and no deterioration in physical properties due to plasticizer is observed.

In this way, the present invention firmly attaches the anti-slip body made of internally plasticized vinyl chloride resin to the lower surface of the base body made of polystyrene foam by two-color extrusion molding. This eliminates the drawback that the anti-slip body peels off during use. In addition, as mentioned above, the anti-slip body is made of internally plasticized vinyl chloride resin that maintains high adhesiveness on its surface, so it adheres tightly to the bathroom floor and is highly slippery. In addition to exhibiting high resistance, unlike vinyl chloride resins that use external plasticizers such as dibutyl phthalate and diheptyl phthalate, there is no migration phenomenon of plasticizers, and there is no risk of staining bathroom floors.

Furthermore, in the case of the present invention, unless the anti-slip body wears out due to wear or the like, a stable anti-slip effect can be obtained at all times, making it ideal for use on slippery surfaces such as bathroom floors.
