Description

Technical Field

[0001] The present invention relates to a non-slip mat disposed on a floor surface wetted with water or a floor surface in water.

Background Art

[0002] Conventionally, when the floor surface of a bathroom, the bottom surface of a bathtub, a poolside, the bottom surface of a pool, the floor surface of a toilet, the floor surface of a kitchen, etc. are wet with water, one may slip and fall. To prevent this, non-slip mats are used. A non-slip mat usually includes a plurality of convex portions on a non-slip surface for making point contact or line contact with the floor surface wetted with water, and groove portions formed between the convex portions and used for drainage.

[0003] As non-slip mats, those having various planar shapes, cross-sectional shapes, or arrangement patterns of the convex portions are known (see, for example, Patent Documents 1 to 5).

Summary of the Invention

Problems to be Solved by the Invention

[0005] As described above, the convex portions of the anti-slip surface in a known anti-slip mat have a contact surface between the drainage passage for draining water on the floor surface and the floor surface, and the shapes of the drainage passage and the contact surface are ingeniously designed. However, particularly under conditions such as waterlogged states or in water, the convex portions may peel off from the contact surface, and the anti-slip effect may not be sufficiently exhibited. For example, when an elderly person or the like uses a bathtub for bathing, an anti-slip mat may be placed on the bottom surface of the bathtub. In the first step of stepping onto such an anti-slip mat, the load applied to the anti-slip mat is relatively low, and the force for stepping on and pressing the anti-slip mat is also weak. Therefore, the anti-slip mat may be prone to lateral slipping. Also, after bathing, when one foot is taken out of the bathtub, the load from the foot remaining on the anti-slip mat is also relatively low, and similarly, the anti-slip mat may be prone to lateral slipping. An object of the present invention is to provide an anti-slip mat that has excellent drainage using groove portions and is difficult to slip laterally even under a low load when placed on a wet floor surface or a floor surface in water.

Means for Solving the Problems

[0006] The present inventors have found that, in an anti-slip mat including a mat main body portion and a plurality of convex portions protruding from its surface, by making the groove portions surrounding the plurality of convex portions on the anti-slip surface have a specific configuration, the above problems can be solved, and the present invention has been completed.

[0007] The present invention is as follows. 〔1〕 A sheet-like anti-slip mat, including a mat main body portion, a plurality of convex portions protruding from the surface of the mat main body portion, a plurality of groove portions formed between the plurality of convex portions and communicating with the peripheral edge of the mat, and comprising: The plurality of groove portions include linear groove portions facing at least four directions in each longitudinal direction, and the anti-slip mat is characterized in that. 〔2〕 The convex portion has an end surface in a plane substantially parallel to the surface of the mat main body portion, and the outer shape of the end surface of at least one of the convex portions is polygonal in plan view. The anti-slip mat according to 〔1〕. 〔3〕The anti-slip mat according to 〔2〕, wherein the outer shape includes a polygon with four or more sides. 〔4〕The anti-slip mat according to 〔3〕, wherein at least three sides of the sides forming the polygon with four or more sides are in the same direction as the three longitudinal directions of the linear groove portions. 〔5〕The anti-slip mat according to any one of 〔2〕 to 〔4〕, wherein the distance from the surface of the mat main body portion to the end surface is 0.3 mm or more. 〔6〕The anti-slip mat according to any one of 〔2〕 to 〔5〕, wherein the end surface abuts on the floor surface of a bathroom or the bottom surface of a bathtub and is arranged.

Advantages of the Invention

[0008] According to the present invention, the anti-slip mat having excellent drainage using the groove portion and placed with the anti-slip surface facing the wet floor surface or the floor surface in water is difficult to slide laterally under a low load state. Also, since the drainage paths using the groove portions are at least in four directions, it is suitable for installation on the floor surface of a bathroom, the bottom surface of a bathtub, a pool side, the bottom surface of a pool, the floor surface of a toilet, the floor surface of a kitchen, etc. For example, when an elderly person or the like sinks and places an anti-slip mat on the bottom surface of a bathtub and takes a bath, the first step of stepping onto such an anti-slip mat has a relatively low load on the anti-slip mat compared to the body weight, and the force to step on and press the anti-slip mat is also weak, so the anti-slip mat may be easily laterally slid. Also, after taking a bath, when one foot is put out of the bathtub, the load from the foot remaining on the anti-slip mat is also relatively low, and similarly, the anti-slip mat may be easily laterally slid. However, when the anti-slip mat of the present invention is used, such problems are suppressed.

Mode for Carrying Out the Invention

[0010] As shown in FIGS. 1 and 2, the anti-slip mat 10 of the present invention includes a mat main body 11, a plurality of convex portions 13 protruding from the surface of the mat main body 11, and a plurality of groove portions 15 formed between the plurality of convex portions 13 and communicating with the peripheral edge portion 16 of the anti-slip mat 10. The plurality of groove portions 15 are characterized by including linear groove portions (straight groove portions) facing at least four directions in each longitudinal direction in a plan view of the mat 10. In addition, the anti-slip mat 10 of the present invention may include curved groove portions in addition to the straight groove portions. The convex portion 13 preferably has a convex end surface 131 in a plane substantially parallel to the surface of the mat main body 11. In this specification, the surface of the mat main body 11 having the convex portion 13 of the anti-slip mat 10 is described as the "anti-slip surface 111 (FIG. 1)", and one surface of the mat main body 11 is described as the "second surface 112 (FIG. 1)". The second surface 112 is the surface on the side that the user touches and steps on. The linear groove portion (straight groove portion) has a substantially rectangular shape with the direction sandwiched between two convex portions 13 as the width and the direction extending in the drainage direction as the length in a plan view. Therefore, all the substantially rectangular groove portions provided on the anti-slip surface 111 side can be regarded as the groove portions 15.

[0011] The pattern of the convex portions 13 on the anti-slip surface 111 of the anti-slip mat 10 of the present invention having the structure shown in FIG. 1 is exemplified in FIGS. 2, 6, and 7, for example. The anti-slip mat 10 of the present invention includes a plurality of convex portions 13 protruding from the mat main body portion 11 on the anti-slip surface 111 and a groove portion 15 communicated with the peripheral edge portion 16 of the anti-slip mat 10. Therefore, the water between the floor surface in contact with the convex portion 13 having the convex portion end surface 131 and the mat 10 can be easily drained. Since this groove portion 15 is formed between the convex portions 13 on the anti-slip surface 111, it is a part of the mat main body portion 11.

[0012] As described above, in the anti-slip mat 10 of the present invention, the convex portion 13 preferably has a convex portion end surface 131 substantially parallel to the surface of the mat main body portion 11. Thereby, when the anti-slip mat 10 of the present invention is placed and used on the floor surface of a bathroom, the bottom surface of a bathtub, etc., the convex portion end surface 131 of the convex portion 13 of the anti-slip mat 10 can surely contact the floor surface and the side surface, and the anti-slip effect can be exhibited. Further, the convex portion 13 has a convex portion side surface 132 (FIG. 4) protruding from the mat main body portion 11 and is connected to the end surface 131. From the viewpoint of drainage, it is preferable that the convex portion side surface 132 protrudes in a direction substantially perpendicular to the surface of the mat main body portion 11.

[0013] Embodiment 1 The anti-slip mat 10 according to Embodiment 1 has an anti-slip surface with a convex pattern shown in FIG. 2, and on the anti-slip surface 111 of the mat main body 11, convex portions 13 whose convex end faces 131 are in contact with the floor surface of a bathroom, the bottom surface of a bathtub, etc., and groove portions 15 through which water flows between the convex portions 13, and a groove portion 15 that is connected to the peripheral edge portion 16 of the anti-slip mat 10 and drains water. In Embodiment 1, the groove portion 15 includes at least groove portions 21 having a regular hexagon shape (reference numeral 21 in FIGS. 2 and 3) indicated by a dotted line, and adjacent groove portions 21 are in a connected state. As shown in FIG. 3, one of the hexagonal convex portions separated by the groove portion 21 is divided into six equal parts in three directions by straight groove portions 15 that start from the center of one side of the regular hexagon-shaped convex portion separated by the groove 21, pass through the center of the regular hexagon, and then extend toward the center of the other opposite side, and a plurality of convex portions 13 separated by the groove portion 21. Further, as shown in FIG. 1, there are groove portions shown in the vertical direction (z-axis in FIG. 1), and from the viewpoint of linear drainage, a configuration is adopted in which a plurality of linear groove portions are provided from one end side to the other end side on the anti-slip surface 111.

[0014] The groove portion 15 that constitutes the anti-slip mat 10 having the convex pattern of FIG. 2 includes, in addition to groove portions 21 whose longitudinal directions are different from each other in three directions (D1, D4, and D6), linear groove portions facing the three directions of D2, D3, and D5 (a total of six directions). Therefore, a plurality of convex portions 13 are at least surrounded by a plurality of linear groove portions facing different directions in each longitudinal direction and exist in an island shape. As a result, the outer shape of the convex end face 131 includes a polygon, and in FIG. 2, it is a quadrilateral with one obtuse interior angle. In the case of a modification of the convex pattern of FIG. 2, for example, the polygon is not limited to a quadrilateral, and can be either or both of a polygon having five or more sides with all interior angles being acute angles and a polygon having five or more sides with at least one obtuse interior angle. Therefore, it is preferable that the polygon, which is the outer shape of the convex end face 131, has four or more sides, that is, a polygon with four or more sides. Further, among the sides forming this polygon, it is preferable that at least three sides are in the same direction as the three longitudinal directions of the linear groove portion.

[0015] In FIG. 2, when a straight line (line A-A and line B-B in the figure) is drawn from one end side to the other end side of the anti-slip surface so as to straddle a plurality of convex portions 13, the outer shape of the convex portion end surface 131 is different from each other or the orientation is different even if the outer shape of the convex portion end surface 131 is the same among adjacent convex portions 13 on the straight line in plan view. When the anti-slip mat 10 is placed so that the convex portion end surface 131 abuts on a wet floor surface or a floor surface in water, for example, when a user places one foot on the anti-slip mat 10 placed on the bottom surface of a bathtub, straddling the wall of the bathtub, and applies a force to the foot placed on the mat in an attempt to maintain balance in a state of low load at the moment of placing one foot, a force is applied to the anti-slip mat 10 in the direction of placing one foot as viewed by the user. When viewed from the anti-slip mat 10, a deviating force in the direction away from the user's direction, that is, a so-called side-slip force, is applied to the anti-slip mat 10, and a stress that resists the side-slip force is applied to the convex portion 13 and the convex portion end surface 131 due to the friction between the convex portion end surface 131 and the floor surface. Here, for example, when the outer shape of the convex portion end surface 131 is circular in plan view (so-called the convex portion 13 is a cylindrical protrusion), the maximum side-slip stress is concentrated at one point at the tip of the circular vertex of the circular convex portion end surface 131 in the sliding direction. Therefore, the area of the convex portion end surface 131 that acts on the anti-slip effect on the concentrated stress (hereinafter also referred to as the "anti-slip effective area") is substantially small, and the contact surface (convex portion end surface 131) of the mat and the floor surface may be peeled off due to inability to withstand the concentrated stress, and the anti-slip mat 10 may slide. On the other hand, since the convex portion 13 of the anti-slip mat 10 of Embodiment 1 is arranged to be surrounded by the groove portion 15 and the groove portion 21 including linear groove portions facing at least in four directions in each longitudinal direction, a plurality of convex portion end surfaces 131 have various outer shapes with different angles at the corners in plan view with respect to the sliding direction. Thereby, even when the same side-slip force is applied to the anti-slip mat 10 in the same state of low load, the sliding stress applied to the convex portion 13 caused by the sliding is dispersed to a plurality of corners. As a result, the effective area substantially involved in the anti-slip action is increased.

[0016] Regarding the convex portions of the anti-slip surface 111 of the anti-slip mat 10, the distance between the surface of the mat main body 11 and the end face 131 of the convex portion (hereinafter referred to as "convex portion height") shown in FIG. 1 is preferably 0.3 mm or more, more preferably 0.4 mm or more, from the viewpoint of facilitating the drainage of water between the floor surface and the end face 131 of the convex portion. On the other hand, if the convex portion height is too high, when a load is applied to the mat main body 11, the convex portion 13 is likely to deform. For example, the convex portion 131 is likely to shear-deform so as to shift in a direction parallel to the surface of the mat main body 11 and the end face 131 of the convex portion. Therefore, the stress applied to the end face 131 of the convex portion is concentrated on a specific portion, and the end face 131 of the convex portion and the floor surface are likely to peel off. Therefore, from the viewpoint of the anti-slip effect, the upper limit of the convex portion height is preferably 5 mm or less, more preferably 2 mm or less, and even more preferably 1 mm or less.

[0017] The width length of the groove portion 15 (including the groove portion 21) sandwiched between the two convex portions 13 is not particularly limited, but from the viewpoint of drainage, it is preferably 0.5 mm or more, more preferably 0.7 mm or more, and even more preferably 1 mm or more. Also, from the viewpoint of increasing the contact area between the end face 131 of the convex portion and the floor surface, the width length is preferably 5 mm or less, more preferably 3 mm or less, and even more preferably 2 mm or less. The width lengths of the groove portion 15 may be the same or different from each other in all widths. Also, the depth (convex portion height) of the groove portion 15 may be the same or different from each other in all widths.

[0018] In the present invention, the anti-slip mat 10 in a preferred embodiment has a structure in which, as shown in FIG. 1, when the convex portion 13 is viewed from the side, the outer periphery of the convex portion 13 that extends from the central portion of the end face 131 of the convex portion and then extends in the direction of the mat main body portion 11 is angled. That is, the convex portion 13 has a convex portion end face 131 and a convex portion side face 132, and the corner portion formed by the convex portion end face 131 and the convex portion side face 132 has a structure in which the peripheral edge of the convex portion end face 131 is angled (hereinafter referred to as "angled structure r"). The angled structure r is an important structure to ensure that the outer periphery of the outer shape of the convex portion end face 131 abuts on the floor surface. As shown in FIG. 4, in a side view, the angled structure r is a part of the circumference of a circle 50 drawn to be inscribed by the convex portion end face 131 and the convex portion side face 132, and the length of the angled structure r is the length of the radius of the circle 50. In FIG. 4, the angle formed by the three points of the contact point between the circle 50 and the convex portion end face 131, the center of the circle 50, and the contact point between the circle 50 and the convex portion side face 132 is shown as 90 degrees, but it may be larger or smaller than 90 degrees. The angled structure r is preferably 0.5 mm or less, more preferably 0.3 mm or less, and still more preferably 0.1 mm or less.

[0019] FIG. 5 is a partially enlarged view of FIG. 2, each including a plurality of convex portions 13 and groove portions 15. The convex portions 13X and 13Y, the outer shape of the end face 131 of which is the same quadrilateral, are arranged in a direction orthogonal to the longitudinal direction of the linear groove portion F1 and adjacent to each other with the linear groove portion F1 therebetween. Further, the convex portions 13X and 13Y are arranged such that at least one (for example, F2 and F3 in the figure) of the longitudinal directions of other linear groove portions surrounding the convex portions 13X and 13Y other than the linear groove portion F1 is different. In the anti-slip mat 10 provided with the convex portion 13 having such an arrangement form on the anti-slip surface 111, in a state of a low load, in the convex portion 13 having a plurality of corner portions in a plan view of the convex portion end face 131, the stress is dispersed to each corner portion on the convex portion end face 131, and the anti-slip effective area becomes large, so that a high anti-slip effect can be obtained on a floor surface wetted with water or a floor surface in water.

[0020] The area of the convex portion end face 131 of the convex portion 13 is not particularly limited, but the area of the circle inscribed therein (per convex portion end face) is preferably 3 mm 2 or more from the viewpoint of increasing the contact area with the floor surface to obtain an anti-slip effect.

[0021] The ratio of the total area of the convex portion end faces 131 of the convex portions 13 to the total area of the anti-slip mat 10 in plan view is preferably 30 to 90%, more preferably 40 to 80% from the viewpoint of ensuring both the contact area between the convex portion end faces 131 of the anti-slip mat 10 and the floor surface on which it is placed and the drainage area of the groove portions 15 of the anti-slip mat 10.

[0022] In the anti-slip mat 10, the total outer peripheral length forming the outer edge of the convex portion end faces 131 included in the mat per 20 mm × 20 mm is preferably 30 mm or more, more preferably 50 mm or more, still more preferably 100 mm or more, particularly preferably 120 mm or more from the viewpoint of dispersing the stress generated by the slipping force and ensuring the anti-slip effect. The upper limit is preferably 500 mm or less, more preferably 400 mm or less, still more preferably 350 mm or less, particularly preferably 250 mm or less from the viewpoint that if the outer peripheral length is made too large, the area of each convex portion end face 131 becomes small and the anti-slip effect deteriorates.

[0023] The surface form of the side peripheral surface of the convex portion 13 is not particularly limited and may be any of a flat surface, a curved surface, and a rough surface.

[0024] The constituent materials of the anti-slip mat 10 are not particularly limited. At least from the viewpoint of ensuring the contact with the uneven or curved floor surface where the convex portion end face 131 abuts, the convex portion 13 preferably consists of an elastic resin material having a Type A durometer hardness measured in accordance with JIS K 6253 in the range of 20 Point to 90 Point, more preferably 40 Point to 80 Point. All of the convex portions 13 may be made of the same material, or may be made of a plurality of types of materials, for example, adjacent convex portions 13 may be made of different materials from each other. Also, adjacent convex portions 13 may have different Type A durometer hardnesses from each other.

[0025] The elastic resin material constituting the convex portion 13 can be, for example, a thermoplastic elastomer or rubber, or a resin composition mainly composed of a mixture of these and a thermoplastic resin. Examples of the thermoplastic elastomer include olefin-based elastomers, styrene-based elastomers, diene-based elastomers, hydrogenated diene-based elastomers, vinyl chloride-based elastomers, chlorinated polyethylene-based elastomers, ethylene-vinyl acetate-based elastomers, polyester-based elastomers, polyamide-based elastomers, fluorine-based elastomers, and the like. Among these, styrene-based elastomers are preferred. Examples of the rubber include ethylene-propylene-diene rubber, nitrile rubber, butadiene rubber, and the like.

[0026] The above elastic resin material may contain, if necessary, a reinforcing material, an inorganic filler, a softening agent, a weather resistance-imparting agent, an antioxidant, an antistatic agent, a flame retardant, a fungicide, a coloring agent, etc. for adjusting specific gravity, flexibility, elasticity, etc.

[0027] The constituent materials of the mat main body portion 11 and the convex portion 13 may be the same as or different from each other. In the present invention, it is preferable that the mat main body portion 11 and the convex portion 13 are an integrated body composed of a continuous phase of the same material. The anti-slip mat 10 may be either a single-layer type composed of all the same material or a laminated type in which different materials are stacked in the thickness direction of the anti-slip mat 10.

[0028] The surface form of the second surface 112 of the anti-slip mat 10 of Embodiment 1 is not particularly limited. For example, it can have a concavo-convex structure with a lattice pattern, a concentric circle pattern, a dot pattern, a pattern with design characteristics, etc. FIG. 1 shows the convex portions corresponding to the design layer 18.

[0029] The thickness of the anti-slip mat 10 including the height of the convex portion (t in FIG. 1) can be set to any thickness as long as the effects of the present invention are not impaired. However, if it is too thin, the strength of the mat itself against tearing and breaking will decrease. On the other hand, if it is too thick, from the viewpoint that the weight is heavy and the mat itself is difficult to bend following the floor surface with a curved surface, the thickness of the mat 10 is preferably 1 mm or more, more preferably 1.5 mm or more, and still more preferably 2 mm or more. On the other hand, the upper limit of the thickness of the mat 10 is preferably 10 mm or less, more preferably 5 mm or less, and still more preferably 4 mm or less.

[0030] The planar size of the anti-slip mat 10 is appropriately selected according to the application and is not particularly limited. For example, from the viewpoint of the weight of the mat 10, it can be sized 20 to 100 cm × 30 to 90 cm.

[0031] The specific gravity of the anti-slip mat 10 measured according to JIS K 7112 is preferably greater than 1.0 from the viewpoint of sinking in water. The upper limit is preferably 4 or less, more preferably 3 or less, and still more preferably 2.5 or less from the viewpoint of facilitating the handling of transportation and laying of the mat 10 of Embodiment 1. If the specific gravity is within a preferable range, the structure and material of the anti-slip mat 10 may use a foam in terms of imparting cushioning properties. Further, the mat main body portion 11 of the anti-slip mat 10 according to the present invention may be provided with through holes penetrating in the thickness direction.

[0032] The method for manufacturing the anti-slip mat 10 is not particularly limited. When the mat main body 11 and the convex portions 13 are made of the same elastic resin material, the anti-slip mat 10 can be manufactured by a conventionally known resin molding method such as injection molding, extrusion molding, or press molding.

[0033] According to Embodiment 1, for example, when an elderly person or the like takes a bath using a bathtub with the anti-slip mat 10 sunk in its bottom surface, the first step of stepping onto such an anti-slip mat is that the load on the anti-slip mat is relatively low compared to the body weight, and the force to step on and press the anti-slip mat is also weak, so the anti-slip mat may be prone to side slipping. Also, after taking a bath, when one foot is taken out of the bathtub, the load from the foot remaining on the anti-slip mat is also relatively low, and similarly, the anti-slip mat may be prone to side slipping. However, when the anti-slip mat 10 of Embodiment 1 is used, such problems are suppressed and the drainage property is also excellent.

[0034] Embodiment 2 The anti-slip mat 10 according to this Embodiment 2 includes an anti-slip surface 111 having a convex pattern shown in FIG. 6. On the anti-slip surface 111 of the mat main body 11, a convex end surface 131 substantially parallel to the surface of the mat main body 11 has convex portions 13 that contact the floor surface of the bathroom, the bottom surface of the bathtub, etc., and a groove portion through which water flows between the convex portions 13, and a groove portion 15 that communicates with the peripheral edge 16 of the anti-slip mat 10 to drain water. In Embodiment 2, on the anti-slip surface 111, first hexagonal convex portions divided by groove portions 23 with dotted lines of hexagons (reference numeral 23 in FIG. 6) shown by dotted lines at the center are formed. Then, inside the outer periphery of the convex portions divided by the regular hexagonal groove portions 23, second hexagonal second convex portions divided by regular hexagonal grooves not communicating with the groove portions 23 are formed. Further, from the central portion of each side of the outer periphery of the first hexagonal convex portions, grooves communicating with the outer peripheral groove portions of the second hexagonal convex portions from three directions are formed by straight grooves 15 directed toward the center of the first hexagonal convex portions. Also, a plurality of regular hexagonal grooves 23 are each formed in a connected state between adjacent groove portions. Also, different from Embodiment 1, the groove portions are formed in a zigzag shape from one end side to the other end side on the anti-slip surface 111 to ensure drainage.

[0035] In the anti-slip mat 10 according to Embodiment 2, the groove portion 15 includes linear grooves facing at least four directions in each longitudinal direction, similar to Embodiment 1. In FIG. 6, linear grooves facing six different directions of D1 to D6 are formed. Therefore, a plurality of convex portions 13 having various outer shapes of the convex portion end face 131 are present in an island shape, surrounded at least by a plurality of linear grooves facing different directions in each longitudinal direction. As a result, the outer shape of the convex portion end face 131 includes a polygon, and in FIG. 6, it includes a hexagonal shape with one obtuse interior angle.

[0036] In the anti-slip mat 10 according to Embodiment 2, the width length of the groove portion 15, the depth of the groove portion 15 (convex portion height), the area and its ratio of the convex portion end face 131, the total outer peripheral length of the convex portion end face 131, etc. can be made the same as in Embodiment 1.

[0037] Embodiment 3 The anti-slip mat 10 according to this Embodiment 3 includes an anti-slip surface having a convex pattern shown in FIG. 7. On the anti-slip surface 111 of the mat main body portion 11, convex portions 13 with end faces 131 substantially parallel to the surface of the mat main body portion 11, which come into contact with the floor surface of a bathroom, the bottom surface of a bathtub, etc., and groove portions through which water flows between the convex portions 13, and a groove portion 15 that is connected to the peripheral edge of the anti-slip mat 10 to drain water. In Embodiment 3, similar to Embodiment 2, on the anti-slip surface 111, first regular hexagonal convex portions separated by groove portions 25 with a dotted hexagon (reference numeral 25 in FIG. 7) as the center of the dotted line are formed. Then, inside the outer periphery of the convex portions separated by the regular hexagonal groove portions 25, second regular hexagonal second convex portions separated by regular hexagonal grooves not communicating with the groove portions 25 are formed. Further, grooves are formed that communicate from the center of each side of the outer periphery of the first regular hexagonal convex portions to the outer peripheral groove portions of the second regular hexagonal convex portions in three directions by linear grooves 15 directed from the center of the first regular hexagonal convex portions. In addition, the plurality of regular hexagonal groove portions 25 are each formed in a connected state with adjacent groove portions. Also, different from Embodiment 1, the groove portions are formed in a zigzag shape from one end side to the other end side on the anti-slip surface 111 to ensure drainage.

[0038] In the anti-slip mat 10 according to Embodiment 3, the groove portion 15 includes linear grooves facing at least four directions in each longitudinal direction, similar to Embodiments 1 and 2. In FIG. 7, linear grooves facing six different directions D1 to D6 are formed. Therefore, a plurality of convex portions 13 having various outer shapes of the convex portion end faces 131 are present in an island shape, surrounded at least by a plurality of linear grooves facing different directions in each longitudinal direction. As a result, the outer shape of the convex portion end face 131 includes a polygon, and in FIG. 7, it includes a hexagonal shape with one obtuse interior angle.

[0039] In the anti-slip mat 10 according to Embodiment 3, the width length of the groove portion 15, the depth of the groove portion 15 (convex portion height), the area and its ratio of the convex portion end face 131, the total outer peripheral length of the convex portion end face 131, etc. can be made the same as in Embodiment 1.

[0040] Note that the present invention is not limited to these embodiments. For example, it can be an anti-slip mat having an anti-slip surface with the convex portion pattern (enlarged view of the main part) shown in FIG. 8. FIG. 8 shows a convex portion pattern in which four convex portions (13K, 13L, 13M, and 13N) having different outer shapes of the end faces are arranged as one unit, and a plurality of groove portions are formed between the convex portions so that these groove portions face four different directions H1 to H4. Since the convex portions in the outer shape of the convex portion end face face in multiple directions, even in a state of a low load on the anti-slip mat, stress is dispersed to the ends and recesses of the plurality of convex portions 13K, 13L, 13M, and 13N of the outer shape of each convex portion end face. As a result, the effective area substantially involved in the anti-slip action becomes large and an excellent anti-slip effect is exhibited.
