Description

  The present invention relates to a non-slip mat used for anti-slip by being placed on the bottom of a bathtub, a bathroom washing place, a pool side or the like.

  FIG. 4 of Japanese Patent No. 4523922 and paragraph 0057 of the specification show an anti-slip mat 10 ′ in which grooves 16 are formed on the entire surface of the surface layer 14.

  According to paragraph 0058 of the specification of the publication, “the groove 16 functions as a drainage groove when the non-slip mat 10 ′ is laid on a wet floor surface, and a plurality of grooves extending linearly in an oblique direction. (As a result, a substantially diamond-shaped concavo-convex pattern is formed on the surface of the surface layer 14.) The end portions of the grooves 16 are formed on the surface layer 14. The groove 16 can function more effectively as a drainage groove. ”.

  Further, in FIG. 5 of Japanese Patent No. 4523922 and paragraphs 0062 and 0063 of the specification, a non-slip mat 10 ′ in which a drain hole 18 penetrating from one surface layer 14 to the other surface layer 14 is formed. When the non-slip mat 10 ″ is used in a bathtub, the hot water can pass through the drain hole 18 and the anti-slip mat 10 ″ has an appropriate resistance. It is said that the non-slip mat 10 ″ can be sunk straight into the bathtub.

  The drain hole 18 in the anti-slip mat 10 ″ described in Japanese Patent No. 4523922 is provided regardless of the groove 16 or the uneven pattern.

  In Design Registration No. 1406966, a column in which a plurality of pairs of convex portions whose bottoms of the substantially equilateral triangular bottom faces each other is arranged at regular intervals so that the bases are arranged in a straight line is half of the regular interval. A non-slip mat is shown on the bottom side in a state where a large number of them are shifted in parallel with each other.

  In addition, Japanese Patent Publication No. 1539454 discloses an anti-slip mat having convex portions of a substantially equilateral triangular bottom surface that are adjacent to each other through a certain groove portion on the entire bottom surface.

  All of these are placed on an underwater target surface such as the bottom of a bathtub containing hot water, or on a target surface with a relatively large amount of water that can exist on the surface, such as a bathroom or a poolside. It is used for anti-slip in the state that has been done, but at the moment when the user rests on the foot or when the user sits down, or when the user rests on the foot or in the state of sitting down, It does not indicate a technique that can effectively prevent sliding against the target surface.

Japanese Patent No. 4523922 Design Registration No. 1406966 Design Registration No. 1539454

  The present invention is placed on an underwater target surface such as the bottom of a bathtub in which hot water is stored, or a target surface with a relatively large amount of water that can exist on the surface, such as a bathroom or a poolside. Even when the user sits on his / her foot or sits down, or when he / she sits on his / her foot or sits down, he / she is effectively prevented from slipping on the target surface. An object is to provide a non-slip mat.

  The non-slip mat of the present invention can be expressed as follows.

(1) An elastomeric anti-slip mat having a predetermined anti-slip part on the bottom side,
Each of the anti-slip portions has one anti-slip convex portion whose bottom surface forms an equilateral triangle shape in a number of the same equilateral triangular regions that share one side and are adjacent to each other. The part is formed in the recess of the lower opening,
The bottom surface of each of the anti-slip projections has a regular triangular shape in which each regular triangle region is concentrically reduced at a constant area ratio of 0.60 to 0.72 and is flat along a certain plane. None,
A portion between the opposing sides of the equilateral triangular bottom surfaces of the adjacent non-slip convex portions among the concave portions is a groove-shaped drain concave portion whose depth is 0.5 to 1.5 times the width of the lower opening. And
The apex part of the equilateral triangle bottom surface of each anti-slip convex part faces the intersecting concave part where the groove-like drainage concave parts intersect at an angle of 60 degrees,
The length of one side of the regular triangular bottom surface of each of the anti-slip convex portions is 2.5 to 7.5 mm, and the regular triangular bottom surface of each anti-slip convex portion is 100 gf / cm at the corresponding portion on the upper surface side. An anti-slip mat characterized in that in the state in which the load of ² is loaded downward, the entire bottom surface can be in close contact with a spherical surface having a radius of 10 m.

This anti-slip mat is made of elastomer, and the length of one side of the bottom surface of the regular triangle shape of each anti-slip convex portion is 2.5 to 7.5 mm, and the bottom surface of the regular triangle shape of each anti-slip convex portion is the top surface In the state where a load of 100 gf / cm ² is loaded downward on the corresponding part on the side, the entire bottom surface can be in close contact with a spherical surface having a radius of 10 m.

  When the non-slip mat made of elastomer is placed on a target surface such as a bottom surface of a bathtub or an upper surface of a bathroom or a poolside with the bottom surface as the bottom, the overall shape of the non-slip mat is a plane, This corresponds to the shape of the target surface such as a curved surface.

  When a load is applied to the elastomeric anti-slip mat in this state while the user is standing on the soles of the feet or sitting down on the hips (sitting on the buttocks), the target surface is not limited to a flat surface. Even if it is a curved surface having a curvature that is at least equal to or less than a spherical surface having a radius of 10 m, the regular anti-slip shape of each non-slip convex portion is a portion of the predetermined anti-slip portion on the bottom surface side where a downward load is loaded. It is easy for the entire bottom surface to be in close contact with the target surface.

  Compare the amount of water that can be present on the surface of the non-slip mat made of elastomer, such as the bottom of a bathtub in which hot water is stored, and the surface of a bathroom such as a bathroom or a poolside, with the bottom facing down. In a state where it is placed on a large number of target surfaces, a certain amount of water (or an aqueous liquid or other liquid. In the following, the term “water” is referred to as an aqueous liquid in the gap between the target surface and the bottom surface of the anti-slip mat. Alternatively, it is also used in the meaning including other liquids), for example, in the form of a film or a thin layer.

  However, the predetermined anti-slip portion on the bottom surface side of the anti-slip mat has one non-slip convex portion whose bottom surface forms an equilateral triangle in each of a number of identical equilateral triangular regions that share one side and are adjacent to each other. And the portions other than the non-slip convex portions are formed in the concave portions of the lower opening, and the bottom surfaces of the respective anti-slip convex portions are concentric with each equilateral triangle region and have a constant value of 0.60 to 0.72. A regular triangular shape that is non-rotated and reduced by the area ratio, has a planar shape along a certain plane, and the portion between the opposite sides of the regular triangular bottom surface of the adjacent non-slip convex portion among the concave portions, It is a groove-like drainage recess whose depth is 0.5 to 1.5 times the width of the lower opening, and the apex of the bottom surface of the regular triangle of each anti-slip projection is that the groove-like drainage recesses are It faces an intersection recess that intersects at an angle of 60 degrees. Therefore, the drainage efficiency through each drainage recess is as good as possible, and the ratio of the area of the equilateral triangle bottom surface of the anti-slip projection on the bottom side is as large as possible.

  Thus, as described above, on the elastomeric anti-slip mat placed on the target surface with the bottom surface at the bottom in a state where a certain amount of pore water exists in the gap between the target surface and the bottom surface of the anti-slip mat, When a person stands on his / her foot or sits down, the target surface is not limited to a plane but a spherical surface having a radius of at least 10 m at a portion of the predetermined anti-slip portion on the bottom side where a downward load is loaded. Even if it is a curved surface with the same or less curvature, the drainage of the interstitial water outward from the portion where the downward load is loaded through the groove-shaped drain recess and cross recess, and one side of each anti-slip projection The contact of the entire bottom surface of the regular triangular shape of 2.5 to 7.5 mm with the target surface is efficiently generated in a very short time, and the moment when the user sits on the non-slip mat on the sole or sits down Or on the sole Even in a state where the lower the state and the waist, it is effectively prevented that non-slip mat slides to the target surface.

  (2) The anti-slip mat according to the above (1), wherein the cross-section of the groove-shaped drain recess is constant.

  (3) The anti-slip mat according to the above (1) or (2), wherein a cross-sectional shape of the groove-shaped drainage recess is a square shape or a trapezoidal shape.

(4) Of the cross recesses, a through hole penetrating the upper surface is formed in the cross recess selected according to a predetermined rule,
The anti-slip mat according to any one of (1) to (3), wherein the through hole does not extend to a regular triangular bottom surface of the anti-slip convex part.

  A through-hole penetrating the upper surface extends into the equilateral triangular bottom surface of the non-slip convex portion in the intersecting concave portion selected according to a predetermined rule (for example, geometric rule) among the intersecting concave portions (for example, at a predetermined ratio). In order to prevent this, the non-slip convex portion is formed while maintaining the area of the equilateral triangular bottom surface.

  The sole of the foot with the user standing on the non-slip mat made of elastomer and placed on the target surface with the bottom face down, with some gap water in the gap between the target surface and the bottom surface of the anti-slip mat In the portion where the downward load is loaded in the predetermined anti-slip portion on the bottom surface side, the target surface is not limited to a flat surface but is at least equal to or less than a spherical surface having a radius of 10 m. Even if it is a curved surface of curvature, the upper surface of the anti-slip mat is discharged through the through holes provided in the intersecting recesses and the drainage of the interstitial water from the portion where the downward load is loaded through the groove-shaped drainage recesses and the intersecting recesses. The drainage to the side and close contact with the target surface of the entire bottom surface of the regular triangular shape having a side of 2.5 to 7.5 mm on each side of the anti-slip projections are efficiently generated in a very short time.

  Since the through hole does not reach the regular triangular bottom surface of the anti-slip projection, the through hole does not cause the slip prevention due to the close contact of the regular triangular bottom surface with the target surface.

  For this reason, the anti-slip mat slides against the target surface even when the user sits on the sole or sits down on the anti-slip mat or when the user sits on the sole or sits down. Can be prevented more effectively.

  (5) When the anti-slip portion is divided into a group of regular hexagonal regions composed of six adjacent equilateral triangular regions, and each regular hexagonal region shares one side and is adjacent to each other, The anti-slip mat according to the above (4), wherein a through hole is formed in the cross recessed portion other than the cross recessed portion located at the center of the regular hexagonal region.

  (6) When the anti-slip portion is divided into a group of regular hexagonal regions composed of six adjacent equilateral triangular regions, and each regular hexagonal region shares one side and is adjacent to each other, The anti-slip mat according to the above (4), wherein a through hole is formed in the intersecting recess located at the center of the regular hexagonal region.

  (7) The above-mentioned (4) to (6), wherein the through hole is inscribed in the apex of the bottom surface of the regular triangle of the anti-slip projection facing the intersecting recess, or is located on the inner side thereof. ) A non-slip mat according to any one of the above.

  In this case, the gap water as described above can be drained as smoothly as possible to the upper surface side of the anti-slip mat through the through hole.

  (8) The non-slip mat according to any one of (4) to (7), wherein a cross-sectional shape of the through hole is a circular shape or a regular polygonal shape having 6 or more corners.

  In this case, the gap water as described above can be more smoothly drained to the upper surface side of the anti-slip mat through the through hole.

  According to the non-slip mat of the present invention, on the elastomeric anti-slip mat placed on the target surface with the bottom surface as the lower side in a state where a certain amount of pore water exists in the gap between the target surface and the bottom surface of the anti-slip mat. When the user stands on his / her foot or sits down, the target surface is not limited to a flat surface in the portion of the predetermined anti-slip portion on the bottom surface side, and the radius is at least 10 m. Even if it is a curved surface with a curvature equal to or less than that of the spherical surface, the drainage of the interstitial water outward from the portion where the downward load is loaded through the groove-shaped drainage recess and cross recess, and each anti-slip projection Adhesion of the entire bottom surface of a regular triangle having a side of 2.5 to 7.5 mm with respect to the target surface efficiently occurs in a very short time, and the user sits down on his / her back on the anti-slip mat or sits down. At the moment Even in a state where the lower the state and waist resting in, it is effectively prevented that non-slip mat slides to the target surface.

The bottom surface of each of the anti-slip projections has a regular triangular shape in which each regular triangle region is concentrically reduced at a constant area ratio of 0.60 to 0.72 and is flat along a certain plane. None,
A portion between the opposing sides of the equilateral triangular bottom surfaces of the adjacent non-slip convex portions among the concave portions is a groove-shaped drain concave portion whose depth is 0.5 to 1.5 times the width of the lower opening. And
The apex part of the equilateral triangle bottom surface of each anti-slip convex part faces the intersecting concave part where the groove-like drainage concave parts intersect at an angle of 60 degrees,
A through-hole penetrating the upper surface is formed in the intersecting recess selected according to a predetermined rule among the intersecting recesses,
The through hole is a non-slip mat that does not reach the regular triangular bottom surface of the anti-slip convex portion, that is, the length of one side of the regular triangular bottom surface of each non-slip convex portion is 2.5 to 2.5. The bottom surface of the regular triangle shape of each anti-slip projection is 7.5 mm, and the entire bottom surface is a spherical surface having a radius of 10 m when a load of 100 gf / cm ² is loaded downward on the corresponding portion on the upper surface side. An anti-slip mat having the same configuration as the above-described anti-slip mat having the “through hole” may be used except that it does not have a configuration of “adhesive”.

  In this non-slip mat, the user sits on the non-slip mat made of elastomer and placed on the target surface with the bottom surface as the lower side in the presence of a certain amount of water in the gap between the target surface and the bottom surface of the anti-slip mat. When the product is placed on the sole with the foot in the standing position or when the user sits down, the downward load is applied through the groove-shaped drainage recess and crossing recess at the part of the predetermined anti-slip part on the bottom side where the downward load is loaded. Discharge of interstitial water outward from the loaded portion, drainage to the top surface of the anti-slip mat through the through-hole provided in the cross recessed portion, and the target surface of the equilateral triangular bottom surface of each anti-slip convex portion Adhesion occurs efficiently.

  Since the through hole does not reach the regular triangular bottom surface of the anti-slip projection, the through hole does not cause the slip prevention due to the close contact of the regular triangular bottom surface with the target surface.

  Therefore, when the user rests on his / her foot or sits down on the anti-slip mat, or when the user rests on his / her foot or sits down, the anti-slip mat slides against the target surface. Is effectively prevented.
