  However, the conventional flooring with many protrusions on the surface can improve design and anti-slip properties, but smooth drainage such as rain water that has fallen on the flooring surface due to many protrusions on the flooring surface. Is blocked, or dust or dirt that has accumulated or adhered to the floor surface is prevented from being swept out (sweeping with a soot, etc.), or dirt that has adhered to the floor material surface is wiped out (wiping with a mop or the like). There was a tendency to be.

The present invention has been made under the circumstances described above, and the problem to be solved is to provide a flooring material that has good slip resistance, good drainage properties, sweeping properties, and wiping properties, and is rich in design. There is to do.
In the present specification, the sweeping property and the wiping property may be collectively referred to as cleaning property, and the drainage property, the sweeping property, and the wiping property may be collectively referred to as drainage / cleaning property.

  In order to solve the above problems, the flooring according to the present invention is a flooring in which a number of strip-like regions are arranged adjacent to each other so that the longitudinal axes of the strip-like regions are parallel to each other. The strip region is formed by a group of ridges oriented in an arbitrary direction, and the intersection angle α (including 0 °) between the longitudinal axis of the strip region and the central axis of the strip in the strip region Are different between adjacent belt-like regions.

In the flooring of the present invention, in all strip regions, the longitudinal axis of the strip region and the central axis of the ridges in the strip region are not parallel, and the intersection angle α does not include 0 °. desirable.
And the total area of the belt-like region where the crossing angle α is 0 ° <α ≦ 15 ° and the belt-like region where 165 ° ≦ α <180 ° occupies 0 to 30% of the area of the floor material surface, The total area of the belt-like region where the crossing angle α is 15 ° <α ≦ 60 ° and the belt-like region where 120 ° ≦ α <165 ° occupies 30 to 70% of the area of the floor surface, and the crossing angle α It is desirable that the total area of the belt-like regions where the angle is 60 ° <α <120 ° occupies 10 to 40% of the area of the flooring surface.

  The floor structure according to the present invention is characterized in that the floor material according to the present invention is laid on the floor surface such that the longitudinal axis of the belt-like region is parallel to the longitudinal axis of the floor surface. It is what.

In the present invention, a typical belt-like region is a rectangular region that can be recognized as a belt-like region having a constant width dimension, such as the belt-like region 1 shown in FIG. It is not a thing, for example, it has a wide part and a narrow part like the strip | belt-shaped area | region 1 shown to FIG. All of the elongated regions that are similar to the belt shape are included, such as those that have been gradually reduced or gradually increased as in the belt-like region 1 in FIG.
A typical axis in the length direction of the belt-like region is a center axis in the length direction of the belt-like region 1 as shown by an axis L in FIG. 2A, but is limited to such a center axis. If the axis is parallel to the length direction of the band-like region 1 like the axis L shown in FIGS. 2B, 2C, and 2D, the one that is off the center of the band-like region 1 may be used. included.
Further, as shown in FIG. 5, the intersection angle α between the longitudinal axis L of the strip region and the central axis Lc of the ridge 2 in the strip region is the intersection of the central axis Lc in the clockwise direction with respect to the axis L. This means an angle, and the intersection angle α includes 0 °, that is, the case where the axis L and the central axis Lc are parallel.

  Like the flooring of the present invention, the band-shaped region is formed by a group of ridges oriented in an arbitrary direction, and the intersection angle α () between the longitudinal axis of the band-shaped region and the central axis of the ridge in the band-shaped region (Including 0 °) is different between adjacent belt-like regions, the direction of the ridges (direction of the central axis) is different for each belt-like region, and the ridges are oriented in various directions for each belt-like region. Therefore, no matter which direction you walk on the flooring, grip force is generated in all directions of 360 ° due to the ridges oriented in various directions for each belt-like region, and good anti-slip properties (anti-slip function) are exhibited. Walking safety. In addition, if the ridges are oriented in various directions for each belt-like region, drainage of rainwater, etc. that has fallen on the surface of the flooring material, and sweeping of dust and dirt that has accumulated and adhered to the surface of the flooring material (sweeping with a soot, etc.) ) And dirt adhering to the surface of the flooring (wiping with a mop or the like) is less likely to be hindered by the ridges, so drainage, sweeping, and wiping are improved. Therefore, the flooring of the present invention eliminates the risk of a pedestrian slipping and falling, and facilitates removal of water pools, dust, dirt, etc. on the flooring surface.

  In addition, when the floor material of the present invention is irradiated with sunlight or illumination light, the ridges are oriented in various directions for each band-like region. The light reflected on the flat surface (the surface of the flat flooring) is divided into a belt-like region that appears bright when it enters the pedestrian's eyes, and a belt-like region where the light reflected on the flat surface appears dark because it is blocked by the ridges. Thus, a beautiful pattern is formed by the difference in brightness between the belt-like regions. And since the light and dark pattern by such a strip | belt-shaped area | region changes every moment with the position of a pedestrian's eye moving, the design which was beautiful and varied was expressed, and the design property of a flooring improves. .

Further, in all belt-like regions, the floor material is configured such that the longitudinal axis of the belt-like region is not parallel to the central axis of the ridges in the belt-like region, and the intersection angle α does not include 0 °. Has the following effects.
That is, on floor surfaces such as outdoor open corridors and balconies, drainage grooves are usually formed along one side in the length direction of the floor surface so that the floor surface gradually decreases toward the drainage grooves. A water gradient is provided. And a pedestrian often walks in the length direction of a floor surface. If the above flooring is laid on the floor surface of such an open corridor or balcony so that the longitudinal axis of each strip region is parallel to the longitudinal axis of each floor region, the projection of each strip region is Since the central axis of the strip is not parallel to the longitudinal axis of the floor surface, and the convex strip is not oriented perpendicular to the width direction of the floor surface (that is, the direction of the water gradient), The obstruction is further reduced and the drainage of the flooring is improved. If sweeping and wiping are performed in the direction of the water gradient (the width direction of the floor surface), dust and dirt can be swept out and wiped out. In addition, since there is no belt-like region where the walking direction and the axial direction of the ridges coincide with each other, the grip force of the flooring is increased and the slip resistance is improved.

As described above, when the flooring is laid on the floor so that the longitudinal axis of the belt-like region and the longitudinal axis of the floor surface are parallel, the longitudinal axis of the belt-like region and the belt-like region In the band-like region where the intersecting angle α with the central axis of the ridge is 0 ° <α ≦ 15 ° and the belt-like region where 165 ° ≦ α <180 °, the ridge is an axis in the length direction of the floor surface. Oriented in a state that is nearly parallel [in other words, a state that is almost perpendicular to the width direction of the floor (the direction of the water gradient)], so walk in the width direction of the floor (for example, after going through a corridor, trying to enter a room) The gripping power when the action is performed) is extremely large, and the slip resistance is good. However, the drainage in the floor surface width direction due to the water gradient is not so good, and the sweeping and wiping properties in the floor surface width direction (water gradient direction) are not so good. Further, since the grip force is not large when walking in the length direction of the floor (for example, an action such as moving along a corridor), it cannot be said that the slip resistance is very good.
On the other hand, in the belt-like region where the crossing angle α is 15 ° <α ≦ 60 ° and the belt-like region where 120 ° ≦ α <165 °, the ridges are oblique 45 ° with respect to the longitudinal axis of the floor surface. Therefore, the non-slip property, the drainage property, and the cleaning property (sweeping property and wiping property) are better than the above-described belt-like region. And, in the belt-like region where the crossing angle α is 60 ° <α <120 °, the ridges are oriented in a state close to parallel to the width direction of the floor surface (the direction of the water gradient). The anti-slip property when walking in the direction is not so good, but the anti-slip property during walking in the length direction of the floor surface is good, and drainage / cleanability (drainage property, sweeping property, wiping property) is very good.
Therefore, in the flooring of the present invention, the total area of the belt-like region where the crossing angle α is 0 ° <α ≦ 15 ° and the belt-like region where 165 ° ≦ α <180 ° is 0 to 30% of the area of the flooring surface. The total area of the belt-like region where the crossing angle α is 15 ° <α ≦ 60 ° and the belt-like region where 120 ° ≦ α <165 ° occupies 30 to 70% of the surface area of the flooring, and the crossing angle α When the total area of the belt-like region where the angle is 60 ° <α <120 ° occupies 10 to 40% of the surface area of the flooring, as demonstrated in the examples described later, the slip resistance and drainage / cleanability are Overall, it is a good flooring material with a good commercial value that also has an excellent design.

  Further, the floor structure of the present invention is the floor material of the present invention laid on the floor surface so that the longitudinal axis of the belt-like region is parallel to the longitudinal axis of the floor surface. All the operational effects of the flooring of the present invention described above are exhibited.

It is a partial top view of the flooring which concerns on one Embodiment of this invention. (A) (b) (c) (d) is a schematic explanatory drawing of the strip | belt-shaped area | region from which each shape differs. (A) (b) (c) (d) is an enlarged partial plan view of both belt-like regions adjacent to each other, and the adjacent forms of the ends of the ridges forming both belt-like regions are different from each other. FIG. An example of a protruding line is shown, (a) is an enlarged plan view, (b) is an enlarged front view, and (c) is an enlarged side view. It is explanatory drawing about the intersection angle (alpha) of the axis line of the length direction of a strip | belt-shaped area | region, and the central axis of the protruding item | line in the strip | belt-shaped area | region. It is a schematic explanatory drawing of the floor structure concerning one embodiment of the present invention.

  The floor material F shown in FIG. 1 has a number of strip-shaped regions 1 arranged adjacent to each other on the surface thereof, and the longitudinal axes L (see FIG. 2) of the strip-shaped regions 1 are parallel to each other. It arrange | positions so that it may become the direction. These band-like regions 1 are formed by a group of ridges made up of a number of ridges 2 oriented in any one direction for each band-like region, and the longitudinal axis L of the band-like region 1 and the ridges 2 The intersection angle α (see FIG. 5) with the axis Lc is different between adjacent belt-like regions.

  The floor material F is mainly composed of thermoplastic synthetic resin such as vinyl chloride resin or olefin resin, or natural rubber or synthetic rubber, and the ridges 2 in each band-like region 1 are formed by embossing rolls. It is formed by a known method such as hot press. This flooring F may be tiled, but it is suitable for outdoor use where rainwater falls or dust and dirt are carried and accumulated by wind and rain, for example, on the floor of an open corridor or balcony of an apartment. A long floor sheet is desirable. Although the dimension is not limited, for example, it is appropriate that the width is about 90 to 210 cm and the thickness is about 1 to 5 mm, and such a long floor sheet has good workability and transportability.

  Each band-like region 1 is formed by a group of ridges composed of a number of ridges 2 oriented in an arbitrary direction. In the case of a long floor material F (floor sheet), each band-like region 1 It is desirable that the direction of each band-like region 1 be aligned on the surface of the flooring F so that the axis L in the lengthwise direction of 1 is parallel to the axis of the longitudinal direction of the flooring F. In other words, in the present invention, the longitudinal axis L of each band-like region 1 does not have to be parallel in a strict sense). If the direction of the belt-like region 1 is arranged in this way, when a long floor material F is laid on a floor surface such as an open corridor as will be described later, drainage and cleanability (sweeping and wiping properties). Has the advantage of improving.

  As described above, the belt-like region 1 includes all the strip-like regions as shown in FIGS. 2A to 2D, or various elongated shapes approximate to the belt-like shape. No grooves or convex ribs are formed that indicate the boundary of the above or the border with the adjacent band-like region. This is because when such grooves and convex ribs are formed, dust and dirt accumulate in the grooves, and sweeping and wiping out of the dust and dirt are hindered by the convex ribs, thereby reducing the cleaning performance.

  In the floor material F of this embodiment, as shown in FIG. 3A, the end portions of the ridges 2 and 2 of both strip regions 1 and 1 at the boundary portion between both strip regions 1 and 1 adjacent to each other. Although they are almost in contact with each other with a very small gap, as shown in FIG. 3 (b), the ends of the ridges 2, 2 of both strip regions 1, 1 are slightly separated from each other. Alternatively, as shown in FIG. 3 (c), the ends of the ridges 2 and 2 of both belt-like regions 1 and 1 may be continuous, as shown in FIG. 3 (d). In addition, the end portions of the ridges 2 and 2 of both belt-shaped regions 1 and 1 may protrude between the ends of the ridges 2 on the other side. In the case of FIG. 3 (a), the end portions of both ridges 2 and 2 are almost in contact with each other, which is the boundary between the belt-like regions 1 and 1, and in the case of FIG. The center between the ends of the ridges 2 and 2 is the boundary between the two strip-like regions 1 and 1, and in the case of FIG. In the case of FIG. 3D, the middle of the portion where the ends of both ridges 2 and 2 enter each other is the boundary between both strip regions 1 and 1. As will be described later, when calculating the area of the belt-like region 1, the area may be calculated based on these boundaries.

  The width of the belt-like region 1 is preferably about 2 to 40 mm (preferably about 5 to 20 mm) in consideration of the pedestrian's shoe width, particularly from the viewpoint of improving the slip resistance. If the width dimension is about this, the number of the belt-like regions 1 that can be stepped on at the same time with one shoe sole is several to several tens, so that the grip force is increased without causing a large bias depending on the walking direction, Good slip resistance is exhibited.

  This flooring F has an intersection angle α (see FIG. 5) between the axis L in the length direction of the belt-like region 1 and the center axis Lc of the ridge 2 in the belt-like region 1 between the adjacent belt-like regions 1 and 1. It has great features where it is different. Like this flooring F, when the strip | belt-shaped area | region 1 is formed by the protruding stripes orientated to arbitrary one directions, and said crossing angle (alpha) differs between the strip | belt-shaped area | regions 1 and 1 adjacent, each strip | belt-shaped area | region The direction of the ridges 2 (the direction of the central axis Lc) differs from one to another, and the ridges 2 are oriented in various directions for each band-like region 1, so that no matter which direction the floor material F is walked, the band-like Grip force is generated in all directions of 360 ° by the ridges 2 oriented in various directions for each region 1, and good anti-slip properties are exhibited to ensure walking safety. In addition, when the ridges 2 are oriented in various directions for each belt-like region 1, drainage of rainwater or the like that has fallen on the surface of the flooring material F, or dust or dirt that has accumulated or adhered to the surface of the flooring material F Sweeping (sweeping with scissors etc.) and wiping off dirt adhering to the surface of the flooring material F (wiping with mop etc.) are less likely to be hindered by the ridges 2, so drainage, sweeping, and wiping properties Will also be improved. Therefore, the floor material F eliminates the risk that the pedestrian slips and falls, and it becomes easy to remove the water pool, dust, and dirt on the floor material surface.

  Further, when the floor material F is irradiated with sunlight or illumination light, the ridges 2 are oriented in various directions for each band-like region 1, so that the ridges 2 are mutually connected depending on the irradiation direction and the irradiation angle of the light beam. A band-like region 1 in which light reflected by a flat surface (flat floor material surface) in between enters the eyes of a pedestrian and appears bright, and a band-like region in which light reflected by the flat surface appears blocked by the ridges 2 and appears dark A beautiful pattern is formed by the difference in brightness between the belt-like regions. And the light and dark pattern by such a strip | belt-shaped area | region 1 changes every moment with the position of a pedestrian's eyes, and since the design which was beautiful and varied was expressed, the design property of the flooring F is also good. It will be greatly improved.

  In this floor material F, any belt-like region 1 has a constant crossing angle α within a range of 0 ° ≦ α ≦ 180 °. In other words, the belt-like region 1 has a crossing angle α of 0 ° (180 °). For example, it is desirable not to provide the belt-like region 1 in which the axis L in the length direction of the belt-like region and the central axis Lc of the ridge 2 are parallel to the floor material surface. As will be described later, when the floor material F is laid on a floor surface such as an open corridor so that the longitudinal axis L of the strip-like region 1 is parallel to the longitudinal axis of the floor surface, the intersection angle α Is provided on the floor surface, the direction of the ridges 2 (the direction of the central axis Lc) of the band-like region 1 is parallel to the axis of the floor surface in the longitudinal direction such as an open corridor. Since it is perpendicular to the width direction (water gradient direction) of the floor surface, the grip force when walking in the length direction of the open corridor is reduced, and drainage by the water gradient and the width direction of the floor surface This is because sweeping and wiping of dust and the like to the surface is hindered by the ridges 2 and it is impossible to sufficiently improve the slip resistance, drainage property, sweeping property, and wiping property.

Further, the belt-like region 1 in which the crossing angle α between the longitudinal axis L of the belt-like region and the central axis Lc of the ridge 2 in the belt-like region is 0 ° <α ≦ 15 °, and 165 ° ≦ α <180 ° The strip-like region 1 is in a state where the ridges 2 are almost parallel to the axis of the floor surface in the longitudinal direction such as an open corridor [in other words, in a state close to a right angle with the width direction of the floor surface (water gradient direction)]. Since it is oriented, it is a region where drainage is not so good, and sweeping and wiping in the width direction of the floor surface are not so good. And since the grip force when walking in the length direction of a floor surface is not large, it is an area | region where slip resistance is not so good.
On the other hand, in the belt-like region 1 where the crossing angle α is 15 ° <α ≦ 60 ° and the belt-like region 1 where 120 ° ≦ α <165 °, the protrusion 2 is in the length direction of the floor surface such as an open corridor. Therefore, the crossing angle α is 0 ° <α ≦ 15 ° and 165 ° ≦ α <180 °. In addition, the belt-like region 1 in which the cleaning property (sweeping property and wiping property) is good and the crossing angle α is 60 ° <α <120 ° is the width of the floor surface such as the ridge 2 is an open corridor. Since it will be oriented parallel to the direction (direction of water gradient), the slip resistance when walking in the width direction of the floor is not so good, but drainage / cleanability (drainage, sweeping, wiping The take-off property is a better region.

Therefore, in order to improve the slip resistance and drainage / cleanability of the floor material F comprehensively, as shown in Table 1 below, the crossing angles α are 0 ° <α ≦ 15 ° and 165 ° ≦ α <180 °. The total area of the band-like region 1 [hereinafter referred to as S (0 to 15)] occupies 0 to 30%, more preferably 5 to 20% of the surface area of the flooring, and the intersection angle α is 15 ° <α. ≦ 60 ° and 120 ° ≦ α <165 °, the total area [hereinafter referred to as S (15-60)] of the strip-like region 1 is 30 to 70%, more preferably 40 to 60% of the area of the flooring surface. The total area of the band-like region 1 in which the crossing angle α is 60 ° <α <120 ° [hereinafter referred to as S (60 to 90)] is 10 to 40% of the area of the floor material surface, more preferably 15 Occupying ˜30%, and the sum of S (0-30), S (30-60), S (60-90) is 100%, It is desirable that the difference angle α is arranged different band region 1 the floor material surface.
Further, in addition to being in the range of the area ratio, the crossing angles α are variously different so that the relationship of S (0-15) <S (15-60) ≧ S (60-90) is established. Desirably, the region 1 is disposed on the floor material surface, and the total area S (90) of the belt-like region 1 having an intersection angle α of 90 ° preferably occupies 5 to 10% of the floor material surface area. .

  Furthermore, the range of the crossing angle α of the band-like region is limited to 10 ° ≦ α ≦ 170 °, and instead of the total area S (0 to 15), the band-like region where the crossing angle α is 10 ° ≦ α ≦ 15 °. And 165 ° ≦ α ≦ 170 °, the total area S (10 to 15) of the belt-like region occupies 0 to 30%, more preferably 5 to 20% of the area of the floor material surface. This is desirable because it further improves the anti-slip property, drainage and cleanability.

  When calculating the total area of the belt-like regions, as described above, the boundaries of the belt-like regions 1 and 1 adjacent to each other are defined, and the crossing angles α are respectively within the above range based on the borders. What is necessary is just to obtain | require an area and total.

  Each ridge 2 of the ridge group forming the band-like region 1 has a substantially rectangular planar shape as shown in FIG. 4A, and both end faces of the ridge 2 are semicircular in order to improve drainage. It is formed in a convex curved surface. However, the ridge 2 need not be limited to such a shape, and may be an elliptical or elliptical planar shape, but from the viewpoint of ensuring drainage and cleaning properties, It is desirable not to use those that have indentations. Further, in order to reduce adhesion of dust, dirt, dirt, etc., and to improve sweeping and wiping properties, as shown in FIGS. Further, a rounded portion 2a is formed at the rising portion to the end face. The upper surface of the ridges 2 and the floor material surface between the ridges are formed as flat surfaces, but may be pear surfaces or fine uneven surfaces.

  The dimensions of the ridges 2 are not particularly limited, but the height dimension H is about 0.3 to 2.0 mm and the width dimension W from the viewpoint of improving the design properties, slip resistance, drainage properties, sweeping properties, wiping properties, and the like. Is preferably set to about 0.1 to 2.0 mm. In addition, it cannot be overemphasized that the length dimension of the protruding item | line 2 is decided depending on the width dimension of the strip | belt-shaped area | region 1, and the said intersection angle (alpha). Moreover, the mutual space | interval of the protrusion 2 (distance between the side surfaces of the adjacent protrusions 2 and 2) is constant within one strip | belt-shaped area | region 1, This mutual space | interval I shall be set to about 0.5-3.0 mm. Is desirable. The relationship between the height dimension H of the ridge 2 and the mutual interval I is preferably such that the relationship of H ≧ I is established from the viewpoint of effectively expressing the above-described bright and dark design by the reflection of light rays.

In addition, in the belt-like region where the crossing angle α is 0 ° <α ≦ 15 ° and the belt-like region where the crossing angle α is 165 ° ≦ α <180 °, the drainage property, the sweeping property, the wiping property, etc. in the water gradient direction are considered. Then, it is desirable to make the height dimension H of the ridges 2 lower than the height dimension H of the ridges 2 in the band-shaped region where the crossing angle α is in the range of 15 ° <α <165 °. Is preferably about 2/3 to 1/2.
In addition, in the belt-like region where the crossing angle α is 0 ° <α ≦ 15 ° and the belt-like region where the crossing angle α is 165 ° ≦ α <180 °, the drainage property, the sweeping property, the wiping property, etc. in the water gradient direction are considered. Thus, it is desirable that the mutual interval between the ridges 2 is wider than the mutual interval between the ridges 2 in the band-shaped region where the crossing angle α is in the range of 15 ° <α <165 °.

  FIG. 6 is a schematic explanatory diagram of a floor structure according to an embodiment of the present invention.

  In this floor structure, an adhesive 4 is applied to a floor surface 3 (concrete ground surface) of an outdoor open corridor using a comb-shaped iron or the like, and the long floor material F is laid on the adhesive and pressure-bonded. A drainage groove 3a is formed along one side in the length direction of the floor surface 3 (one side on the outdoor side), and the floor surface 3 is gradually lowered toward the drainage groove 3a. A gradient is provided in the width direction of the floor surface 3. The long floor material F is laid such that its longitudinal axis (not shown) is parallel to or coincides with the longitudinal axis (not shown) of the floor surface 3 of the open corridor. The lengthwise axis L of each strip-like region 1 disposed on the surface of the material F is also parallel to the lengthwise axis of the floor surface 3.

  The floor structure in which the floor material F is laid and bonded to the floor surface 3 of the open corridor as described above is a ridge that is oriented in various directions for each strip region 1 regardless of the direction of walking on the floor material F. 2 gives an appropriate grip force in all directions of 360 °, and exhibits a good anti-slip property. In addition, rainwater or the like that has fallen on the surface of the floor material F flows between the ridges 2 of each band-like region 1 in the direction of the water gradient (the width direction of the floor surface 3), and is drained to the drain groove 3a. Therefore, the drainage is good, and the dust, dirt, dirt, etc. deposited on and adhered to the surface of the flooring F can be easily swept or wiped in any direction with a jar or mop. The wiping property is also greatly improved. In particular, the sweeping property and the wiping property in the width direction (water gradient direction) of the floor surface 3 where the sweeping and wiping inhibition by the ridges 2 are most unlikely to occur are good. Therefore, this floor structure eliminates the risk of a pedestrian slipping and falling, and has the effect of facilitating the removal of water pools on the surface of the flooring material F, dust, dirt and dirt.

  Next, the effect confirmation test performed on the flooring of the present invention will be described.

Further, as a flooring material for comparison, a flooring material having a length of 90 cm and a width of 45 cm, and a large number of ridges having a height dimension of 0.7 mm and a width dimension of 1.5 mm on the entire surface, 1.5 mm The flooring formed in the length direction of the flooring was prepared with a space between each other. The floor material used in the vertical direction was used as the floor material of Comparative Example 1, and the floor material used in the horizontal direction was used as the floor material in Comparative Example 2.

[Test method]
About the flooring material of Examples 1-4 and the flooring material for a comparison, anti-slip property and sweeping-out property were evaluated.
The anti-slip property was evaluated with respect to the length direction and the width direction of the flooring based on the test method of JIS A 1454.
Further, the sweepability was evaluated by the following method with the sweep direction as the width direction of the flooring. That is, on a table inclined at 15 °, the flooring is fixed sideways so that the flooring is inclined at 15 ° in the width direction, and 100 g / m ^{2 of} pure sand (particle size less than 120 μm) is sprayed on the surface. Then, the floor material was swept 5 times in the direction in which the floor material tilted with a heel (hair length 40 mm), the amount swept from the floor material was measured, and the sweep removal rate was calculated from the following formula and evaluated.
Sweep removal rate = (amount of removed sand sand / amount of spread sand sand) × 100
The results are shown in Table 2 below.

  In Table 2, ◎ of the judgment code of each performance is extremely preferable (100 to 90% in the sweep removal rate), ○ is preferable (90 to 80%), Δ is conformity (80 to 60%), and x is Inappropriate (60 to 0%).

As can be seen from Table 2, each of the flooring materials of Examples 1 to 4 can achieve both slip resistance and sweeping performance, but S (15 to 60) is 50% like the flooring material of Example 1. And then, S (60-90) is as high as 30%, and S (0-15) is as low as 20%, which is excellent in slip resistance in the length direction of the flooring, and in the width direction. Is also good. On the other hand, the flooring of Example 3 has a low S (60 to 90) of 15% and a high S (15 to 60) of 65%. Good slip resistance and sweeping performance. Moreover, since the floor material of Example 2 has S (0 to 15) being 0% of the lower limit and S (60 to 90) being as much as 40% of the upper limit, the floor material is excellent in slip resistance in the length direction. The anti-slip property in the width direction is normal. And since the floor material of Example 4 has many S (0-15) with 30% of an upper limit, and S (60-90) has few with 10% of a minimum, although it is excellent in the anti-slip property of the width direction of a flooring. In the longitudinal direction, slip resistance and sweeping are normal.
From these, S (0 to 15) is effective in improving the anti-slip property in the width direction of the flooring material, but is hardly useful for improving the anti-slip property and sweeping out property in the length direction. It can be judged that the range of 0 to 30% is appropriate. Further, S (60 to 90) is effective for improving the slip resistance in the length direction of the flooring material and improving the sweeping property, but is hardly useful for improving the slip resistance in the width direction. It can be judged that the range of 10 to 40% is appropriate. Moreover, S (15-60) is effective in improving the anti-slip property and sweeping property in the length direction and the width direction of the flooring, and the area ratio is from S (0-15) or S (60-90). It can be determined that a floor material in which anti-slip performance and sweep-out performance are balanced in total can be obtained by increasing the size.
Further, the floor material of Comparative Example 1 is turned sideways, such as the floor material of Comparative Example 1, in which ridges are formed on the entire surface in the length direction of the floor material, and the floor material of Comparative Example 2 The one used in the above exhibits excellent anti-slip properties in either the length direction or the width direction of the flooring material, but cannot exhibit anti-slip properties in the other direction, and also has a sweepability. Since it can be exhibited only in one direction and not in the other direction, it can be determined that the floor material is inappropriate.

The floor materials of Examples 1 to 4 and the floor materials of Comparative Examples 1 and 2 were laid on the floor surface in a dark place and observed by irradiating light from a light source fixed at an arbitrary position.
In the observation of the flooring materials of Comparative Examples 1 and 2, no difference in brightness due to the reflection of irradiation light was observed.
On the other hand, in the observation of the flooring materials of Examples 1 to 4, it was confirmed that in any flooring material, light and darkness was generated in each band-like region and an excellent aesthetic appearance was achieved. Furthermore, it was confirmed that when the observer walks, the brightness and tone of each belt-like region that is visually recognized and its tone move with slight changes, and an extremely novel design feeling can be obtained.
