DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat made of natural rubber or synthetic rubber, with a mat having a concave and convex geometric shape on the front and back surfaces thereof. Drain holes that penetrate through the floor, and are laid on the floor surface around water areas such as bathrooms, kitchens, and poolsides. The present invention relates to a mat having a rubber hardness in the range of 30 to 90 degrees for preventing slipping or falling of a person due to wetness of the mat.

[0002]

2. Description of the Related Art Floors around water areas, such as bathrooms, kitchens, and poolsides, become slippery when wet with water. In particular, in the washing area of the bathroom, the floor surface is not only water but also soapy water,
Older and disabled people and their caregivers are at risk of slipping and falling because they are more slippery because they are wetted by detergent liquids such as shampoo water. However, there is no commercially available product to prevent this. For example, there is a wooden or synthetic resin cage or a plate made of a foamed synthetic resin such as polyvinyl chloride or polyethylene as the one to be placed in a washing place in a bathroom. However, the latter products emphasize cushioning properties, and many of these products are labeled with "caution from slipping". In addition, although it is not without rubber material, it is a thin sheet-like material, even if it is laid in a bath, it rolls up itself, water, soapy water, shampoo water etc. collects on the sheet surface, and it slides And the risk of falling. Therefore, there is no product suitable for laying on a floor around a water area such as a bathroom, a kitchen, a poolside, etc. to prevent the danger of slipping and falling.

[0003]

The floor around a water area such as a bathroom, a kitchen, and a poolside becomes slippery when wet with water. In particular, in a washing room of a bathroom, the floor surface is more slippery because it is wetted with not only water but also a detergent solution such as soapy water and shampoo water, and the elderly and disabled persons and their caregivers are at risk of slipping and falling. Have been. The present invention, bath, kitchen, laid on the floor around the water around the pool,
This is a mat invented to prevent the danger of slipping and falling of a person.

[0004]

A rubber material (natural rubber and various synthetic rubbers) is used as a mat material, and the mat does not slip even when force is applied to the front and back surfaces of the mat in any direction. The surface of the mat and the back of the mat are designed so that they do not move, so that various detergent liquids such as soap, shampoo, food and dishwashing detergents do not collect above and below the mat. Drainage grooves and drainage holes penetrating the drainage grooves on the front and back surfaces were provided.

[0005] The rubber hardness of the mat surface in contact with the foot is softened to improve the feel of the foot, and the adhesion to the foot is increased to make it hard to slip. The back surface is generally used as a floor material in a washing room in a bathroom. The rubber hardness according to the type of floor material is set so that the mat itself does not easily move on the floor of a ceramic resin, a marble, or a synthetic resin such as FRP. The range of the rubber hardness is 30 to 90 degrees for both the front and back surfaces, and the combination is within the range. However, if necessary, the hardness may be the same.

[0006] The mat is used alone,
There is a type having a coupling mechanism that can sequentially connect one by one to form a mat having a size suitable for the size of a floor surface to be laid. In addition, when the peripheral portion is joined to the one used alone, the peripheral portion is formed in a triangular shape so that a person does not trip and the step between the mat and the floor surface is eliminated.

[0007] A mat having these characteristics is obtained by vulcanizing and molding a mat of an arbitrary size using a mold processed to obtain a predetermined uneven geometrical shape.

The mat has drainage grooves on the front and back sides of the mat and drain holes that penetrate through the drainage grooves on the front and back sides so that various detergent liquids such as shampoo, food and dishwashing detergent do not collect on the top and bottom of the mat. Excellent drainage not only on the floor but also on the floor.

[0011] There are two types of mats: one that is used alone, and one that has a coupling mechanism that can be connected one by one to form a mat having a size suitable for the size of the floor to be laid. In addition, when the peripheral portion is joined to the one used alone, the peripheral portion is formed in a triangular shape so that a person does not trip and the step between the mat and the floor surface is eliminated.

By mixing a dye or a pigment in the rubber material, a colorful mat can be formed, and the atmosphere in the bathroom, kitchen or poolside can be enhanced.

The addition of an antibacterial agent makes it difficult for mold to grow on the mat, and can maintain hygiene.

By mixing rice husk, wood flour, sand, etc., a new design can be made inexpensively and easily without adversely affecting the processability and physical properties of rubber.

The anti-slip mat is as shown in Table 1.
A mixture of 22 kinds of compounding ingredients according to compounding formulas A to H is kneaded for 30 minutes by a 16-inch open roll having a surface temperature of 40 to 60 ° C., and vulcanized and molded using a predetermined mold. .
