Description

  The present invention relates to a mat, for example, a mat made of synthetic resin, having a large number of through holes through which water flows down in an upper board portion on which a person or an object is placed.

  Conventionally, a wide variety of mats have been proposed and marketed as mats having a large number of through holes in an upper board part on which a person or an object is placed, for example, a mat made of synthetic resin.

  Many through holes in the upper plate of the conventional mat are mainly used for mud and moisture such as carts, wheelchairs, bicycles, etc. It is provided in order to discharge moisture from sprinkling or the like downward.

  For example, a mat body of a synthetic resin mat described in Japanese Patent Application Laid-Open No. 8-333875 is constituted by a plurality of blocks 2 in a substantially square shape in plan view, and the substrate 21 of each block 2 is formed in a lattice shape. As a result, a large number of through holes are provided, and support posts 22 are projected from the bottom surface of the substrate 21 at appropriate intervals.

  A mat body 2 of a synthetic resin mat described in Japanese Patent Laid-Open No. 10-159315 is divided into a total of nine blocks 5, and each block 5 includes a substrate 6, a support column 7, and a block 6, respectively. Each substrate 6 is formed in a substantially square lattice plate shape having a large number of holes on the plate surface.

  Although such a conventional mat is provided with a through-hole itself, there is no one that pays attention to the point that the moisture content on the upper board is kept as low as possible by discharging the moisture downward. .

JP-A-8-333875 Japanese Patent Laid-Open No. 10-159315

  The present invention has been made in view of the above-described problems existing in the prior art, and the object of the present invention is to provide an upper plate portion of the mat even when the mat is wet with rain water or other water. It is an object of the present invention to provide a mat that can maintain a relatively low moisture content and is excellent in anti-slip and moisture removal effects.

The mat of the present invention that achieves the above object
An upper board part on which an object is placed, and a support part that supports the upper board part above the placement surface, the mat having a large number of through holes in the upper board part,
The peripheral part of the said through-hole part has a projection part provided with the edge part which stands | starts up toward the inner side of a through-hole part and extends toward the downward or diagonally downward direction.

  The peripheral portion of the through-hole portion has a protrusion having an edge portion extending downward or obliquely downward, and the direction of the peripheral portion of the through-hole portion and the edge portion intersects in plan view.

  Water (for example, water transferred from wet feet or shoes, water dripped from an umbrella or other things, water due to rain or watering, etc.) is located on the upper surface around the through hole portion of the upper board portion. When a part of the water reaches the edge portion of the protrusion, the water rises inward of the through hole portion and is guided downward through the edge portion extending downward or obliquely downward. Thereby, the water on the upper surface around the through hole portion of the upper board portion is sequentially and efficiently discharged downward along the edge portion of the ridge portion through the through hole portion.

  As described above, even when the mat is wetted by rain water or other water, the upper surface of the upper board portion of the mat can maintain a relatively small amount of water, and thus has excellent effects such as anti-slip and water removal. .

  In the mat of the present invention, the edge portion of the protruding portion may extend downward or obliquely downward from the lower side of the through hole portion.

  In this case, in this case, when water is located on the upper surface of the upper board portion around the through hole portion, and when a part of the water reaches the edge portion of the projection portion below the through hole portion, The water is guided downward along the edge. Thereby, the water on the upper surface around the through-hole portion in the upper board portion is sequentially and efficiently discharged downward through the through-hole portion, along the edge portion of the projection portion.

  In the mat of the present invention, the edge portion may extend downward or obliquely downward along a certain vertical plane.

  In this case, since the edge portion extends downward or obliquely downward along a certain vertical plane, the water transmitted through the edge portion is efficiently guided downward.

  Further, in the mat of the present invention, two or more edge portions extending downward or obliquely downward from different positions in plan view in the peripheral portion of one or two or more through-hole portions are located below the through-hole portions. Collectively, at least the lower end portions of the edge portions may be suspended below the upper board portion. The lower end portion of the edge portion can be a position where two or more edge portions are gathered, or one edge after gathering can extend below the gathering position to reach the lower end portion. After some of the three or more edge portions are gathered, another edge may be gathered below that.

  In this case, two or more edge portions extending downward or obliquely downward from different positions in a plan view at the peripheral edge of one or two or more through-hole portions gather together below the through-hole portion. The water that flows down along each edge also gathers.

  In this way, by increasing the amount of water due to the gathering, the dripping of water from the lower end of the edge portion hanging below the upper board portion is promoted, and the flow of water at each upstream edge portion is reduced. Contributes to facilitation. Thereby, the flow of water from different positions in a plan view at the peripheral edge of one or two or more through-hole portions can be made efficient.

  The said support part shall have a water droplet guide groove-shaped part of the direction which the said support part inclined in the up-down direction or the angle of 45 degrees or less with respect to the up-down direction at the side peripheral surface part.

  In this case, when water is located on the upper surface of the upper board portion around the through-hole portion and a part of the water reaches the water droplet guide groove-like portion of the side peripheral surface portion of the support portion, the water is It is guided downward by the water droplet guide groove-shaped portion in a direction inclined at an angle of 45 degrees or less with respect to the vertical direction or the vertical direction.

  Therefore, the water on the upper surface around the through-hole portion in the upper board portion is guided to the water droplet guide groove-like portion on the side peripheral surface portion of the support portion through the through-hole portion, and is sequentially efficiently discharged downward. .

  In the mat of the present invention, the upper surface of the partition part that divides the periphery of the through hole part in the upper board part may be inclined downward toward the through hole part.

  In this case, when water is located on the upper surface of the partition part that divides the periphery of the through hole part in the upper board part, the water easily flows into the through hole part. Easy to be discharged.

  The mat of the present invention has a large number of protrusions on the upper surface of the partition part to prevent water droplets from being held in that position, and the interval between the protrusions is an adjacent protrusion on the upper surface of the partition part. It can be an interval at which water droplets are not retained due to surface tension.

  In this case, when water is positioned on the upper surface of the upper board portion around the through-hole portion, the protrusion prevents the water droplet from being held at that position, and the adjacent protrusion on the upper surface of the partitioning portion. Since water droplets are also prevented from being held by surface tension between them, water on the upper surface of the upper board portion around the through hole portion flows into the through hole portion and is easily discharged efficiently through the through hole portion. . Moreover, the anti-slip | skid effect can also arise with a protrusion.

  In the mat of the present invention, even when the mat is wetted by rain water or other water, the upper surface of the upper board portion of the mat can maintain a relatively small amount of moisture, which is effective for preventing slipping and removing moisture. Excellent.

  The mat M has a planar shape (for example, on a certain plane) so that a large number of element mat bodies E whose basic shape in a plan view has a square shape with a substantially constant dimension form a grid pattern with a predetermined gap therebetween. ) The adjacent element mat bodies E are connected to each other through the connecting portion J in the state of being adjacently arranged. The overall shape is substantially square in plan view. However, as the shape of the mat (and the element mat body) of the present invention in a plan view, a rectangular shape or other shapes (for example, various polygons, circles, ellipses, etc.) can be adopted. Further, the basic shape and dimensions of each element mat body in the mat body are not necessarily constant. In addition, the mat of the present invention does not necessarily require that such a large number of element mat bodies are connected.

  In this mat M, the entire mat M including the joint portion J and the element mat body E is a synthetic resin (for example, an olefin resin such as polypropylene. For example, a non-water-absorbing or non-water-permeable material other than the synthetic resin may be used. Can be integrally molded. The mat M can be adjacently connected to the same other mat M in a plan view, and the connection can be released. In this mat M, as a means for connection and connection release, a connection loop portion L is provided on any two adjacent sides, and a connection protrusion that can be fitted to and removed from the connection loop portion L on the other two adjacent sides. P is provided. It should be noted that the mats M are not necessarily required to be connected and disconnected.

  Each element mat body E supports an upper board part 10 (an upper board part 10 on which a person or an object is placed) on which an object is placed, and the upper board part 10 above a placement surface such as a floor surface or the ground. A plurality of substantially circular column sections 12 and flat plate-like vertical plate portions 14 or bent plate-like vertical plate portions 16 (corner portions of the element mat body E). The support column 12 has a water droplet guide groove-shaped portion 18 in the vertical direction (the vertical tilt direction, for example, a direction tilted at an angle of 30 degrees or less with respect to the vertical direction) on the side peripheral surface portion. In addition, as a support part, a support wall etc. can be employ | adopted other than the support | pillar of various cross sections, the flat plate-shaped vertical plate part 14, or the bending plate-shaped vertical plate part 16, for example. A plurality of types of support portions can be used as in this example, and only one type of support portions can be provided.

  The upper board portion 10 has a lattice shape and has a large number of rectangular through holes 20 penetrating in the vertical direction over the entire upper surface of the upper board portion 10. The rectangular through-hole portion 20 has a cross-sectional shape in the vertical direction (vertical side direction) and the horizontal direction (horizontal side direction) of the element mat body E having a square shape. They are aligned via the partition 22. In any column and any row, the through-hole portions 20 are aligned in alternate directions of vertical, horizontal, vertical, and horizontal. In addition, as a shape in planar view of the through-hole part 20, a square, a triangle, other polygons, a circle | round | yen, an ellipse etc. can be employ | adopted suitably, and it has a through-hole which has multiple types of shape, a magnitude | size, etc. It can also be. When there is a possibility that the mat may be stepped on with shoes, the size of the through-hole portion 20 can be set such that the heel of the high heel is not inserted. Moreover, the through-hole part 20 does not necessarily need to be evenly provided on the entire upper surface of the upper board part 10 of the mat, and does not necessarily need to be aligned. For example, a predetermined part of the upper board part 10 can have a through hole part, and further, a part of the upper board part 10 that does not have a through hole part has a flocked part, a pile part, etc. You can also.

  In each element mat body E, a partition section 22 (including a cross-shaped section partitioning each through hole section 20 and a square outer peripheral section of the element mat body E) that divides the periphery of each through hole section 20 has strength and rigidity. In order to realize light weight and cost reduction while ensuring, it is formed in the groove-shaped cross section of the lower opening. The upper surface of the partition portion 22 is an angle of about 20 degrees with respect to the horizontal direction toward the side (for example, the side of the through-hole portion 20, the gap between the adjacent element mat bodies E or the outside of the mat M). Inclined down. In this case, when water is located on the upper surface of the partition part 22 that divides the periphery of the through hole part 20 in the upper board part 10, the water easily flows into the through hole part 20. It is easy to drain water efficiently. In addition to the fixed angle (for example, 5 to 45 degrees, preferably 10 to 30 degrees with respect to the horizontal direction), the downward inclination angle of the upper surface of the partition portion 22 changes, for example (for example, the inclination angle toward the side). (A curved inclined surface that increases or decreases).

  Fin-shaped protrusions 24, 26, and 28 are formed on the lower side of the partition 22 that forms one side of each through hole 20. Edge portions 24 a, 26 a, and 28 a of the protrusions 24, 26, and 28 (end edges of the fin-like protrusions 24, 26, and 28) are inward of the through-hole portion 20 at the periphery of the through-hole portion 20. Edge portions 24 a, 26 a, and 28 a that rise toward the bottom, and the lower end of the side surface facing the through hole portion 20 of the partition portion 22 is the upper end (starting end), and is substantially continuous with the side surface (therefore, the After extending downward (without projecting inwardly), it is inclined downward toward the outer side as viewed from the through hole 20 and reaches the lower end (terminal). The lower end position of the edge portion can be higher than the lower end of the mat, or the edge portion can reach the lower end of the mat. The edge portions 24a, 26a, and 28a in this example extend downward or obliquely downward along a certain vertical plane. Examples of the edge portion include, in addition to the fin-shaped portion, an end edge portion (ridge portion where the protruding ends are connected) of a protruding portion such as a protruding portion or a plate-like protruding portion.

  The lower end position of the fin-like protrusion 24 provided on the inner part (position other than the outer peripheral part) of the element mat body E is higher than the lower end position of the element mat body E (and therefore the mat M). It hangs downward. The fin-like protrusions 24 at positions other than the outer peripheral part in the element mat body E form a vertical protrusion that intersects in a cross shape in plan view, and the edge of each protrusion 24 that forms the cross shape is an edge part. 24a is formed. FIG. 5 shows one protrusion 24 among the four protrusions 24 having a cross shape. The four protrusions 24 having a cross shape are suspended below the upper board 10. The edge portions 24a of the four projecting portions 24 having a cross shape extend downward from the lower sides of the four adjacent through-hole portions 20, and then incline downward and downward as viewed from the respective through-hole portions 20. They gather at the lower end.

  One protrusion 26 is provided at each of the four corners of the element mat body E, and an edge 26a formed by the end edge of the protrusion 26 extends downward from the bottom of one through hole 20. After that, as viewed from the through-hole portion 20, it is inclined downward and connected to the corner of the bent plate-like vertical plate portion 16.

  The protrusions 28 in portions other than the four corners of the outer periphery of the element mat body E have a Y shape in plan view. The base portion 281 of the projection portion 28 is connected to the flat plate-like vertical plate portion 14, and the bifurcated portion 282 of the projection portion 28 is provided below the two adjacent through-hole portions 20. The edge portion 28a formed by the projecting portion 28 has a portion formed by the end edge portion of the bifurcated portion 282 extending downward from the lower side of the two adjacent through-hole portions 20, respectively. Inclined downward as viewed from the hole 20, gathered at one edge formed by the base 281, and further inclined downward to the vertical middle position of the corner of the folded plate-like vertical plate 16. Has reached.

  The edge portion projects from the peripheral portion of the through hole portion, that is, from the through hole portion or from the position protruding above the through hole portion into the through hole portion or from the lower side of the through hole portion. Without projecting or projecting to the inner side of the part, it may be downward or diagonally downward (some are downward, and other parts are diagonally downward. The diagonally downward is, for example, 30 degrees or more with respect to the horizontal direction. A downward inclination at an angle, preferably 40 degrees or more, more preferably 45 degrees or more, and even more preferably 60 degrees or more, is a downward inclination toward the outer side or the inner side of the through hole portion. It can be extended towards).

  The edge portion rises inward of the through hole portion. That is, in the plan view, the rising direction of the peripheral edge portion and the edge portion of the through-hole portion intersects each other (thus, in the plan view, the rising edge direction of the peripheral edge portion and the edge portion is not parallel. In the plan view, it forms a cross shape with an angle of 15 to 90 degrees).

  The start part of the edge part can be located at an intermediate position between both ends of one side of the through-hole part, and can be located at one end part (corner part) of the side. In the case of a shape having no side such as a circle or an ellipse in a plan view, it can be set to an arbitrary position. Further, one or more edge portions can be provided for one through hole portion or, for example, one side of one through hole portion.

  Each of the locations where the four corners of the through-hole portion 20 are located on the upper surface of the partition portion 22 has a protrusion 30 for preventing water droplets from being held in that position. The interval between the protrusions 30 is an interval at which water droplets are not held between the protrusions 30 on the upper surface of the partition part 22 due to surface tension.

  In this case, when water is positioned on the upper surface of the upper board portion 10 around the through-hole portion 20, the water droplets are prevented from being held in that position by the protrusion 30, and the upper surface of the partition portion 22. Since water droplets are also prevented from being held by surface tension between adjacent protrusions 30 in the water, water on the upper surface of the upper board 10 around the through hole 20 flows into the through hole 20 and the through hole It is easy to be discharged efficiently through 20.

  For example, the protrusion has a maximum dimension in a plan view (diameter in the case of a circle, one side in the case of a square, and long side in the case of a rectangle) that is equal to or less than the width of the partition 22 around the through hole 20. Yes, and the height can be between 0.3 mm and 5 mm. Preferably, the maximum dimension in a plan view is 0.6 to 0.8 times the width of the partition part 22 around the through-hole part 20 and the height is 0.5 to 0.8 mm.

  Water (for example, water transferred from wet feet or shoes, water dripped from an umbrella or other things, water by rain or sprinkling, etc.) on the upper surface of the upper board portion 10 around the through-hole portion 20, that is, rainwater , Water-based liquids containing various other components), and a part of the water flows downward through the through-hole portion 20 to the edge portions 24a, 26a, and 28a of the protruding portions 24, 26, and 28a. When it reaches, the water rises inward of the through-hole portion 20 and is guided downward through the edge portions 24a, 26a, and 28a extending downward or obliquely downward. As a result, water on the upper surface of the upper board portion 10 around the through hole portion 20 is sequentially and efficiently discharged downward through the through hole portion 20 through the edge portions 24a, 26a, and 28a of the ridge portion. Is done. Since the edge portions 24a, 26a, and 28a extend downward or obliquely downward along a certain vertical plane, the water transmitted through the edge portions 24a, 26a, and 28a is efficiently guided downward.

  Further, the fin-like protrusions 24 at positions other than the outer peripheral part in the element mat body E form vertical protrusions that intersect in a cross shape in plan view, and each of the edge parts 24a has four adjacent through holes. After extending downward from the lower side of the portion 20, the four edge portions 24 a are gathered at the lower end portion and inclined downward as viewed from the through-hole portions 20, and are suspended below the upper board portion 10. Yes. For this reason, the amount of water flowing down along the four edge portions 24a is increased by aggregation, so that the dripping of water from the lower end portion of the edge portion 24a hanging below the upper board portion 10 is promoted, and its upstream side. This also contributes to the smooth flow of water at each edge 24a. Thereby, the flow of water from different positions in a plan view at the peripheral portions of the four through-hole portions 20 can be made efficient.

  Further, when water is located on the upper surface of the upper board portion 10 around the through-hole portion 20 and a part of the water reaches the water droplet guide groove-like portion 18 on the side peripheral surface portion of the support portion, the water is Since the water droplet guide groove 18 in the vertical direction is guided downward, the water on the upper surface of the upper board portion 10 around the through hole portion 20 passes through the through hole portion 20 to the side peripheral surface portion of the support portion. It is guided to the water droplet guide groove-like portion 18 and efficiently discharged downward.

  Furthermore, since the upper surface of the partition part 22 which divides the circumference | surroundings of the through-hole part 20 in the upper board part 10 inclines downward toward the through-hole part 20, the circumference | surroundings of the through-hole part 20 among the upper board parts 10 are included. When water is located on the upper surface, the water tends to flow downward through the through-hole portion 20.

  Furthermore, when water is located on the upper surface of the upper plate portion 10 around the through-hole portion 20, water droplets are prevented from being held at that position by the protrusion 30 and the upper surface of the partition portion 22. Since water droplets are also prevented from being held by surface tension between adjacent protrusions 30 in the water, water on the upper surface of the upper board 10 around the through hole 20 flows into the through hole 20 and the through hole It is easy to be discharged efficiently through 20. In addition, a non-slip effect is produced by the protrusion 30.

  In this way, even when the mat is wetted by rain water or other water, the upper surface of the upper board portion 10 of the mat can maintain a relatively small amount of moisture, so that the effect of anti-slip and moisture removal can be maintained. Excellent.
