  The conventional perforated rubber mat is difficult to handle if it is a single piece having a large size, and is inconvenient to carry. Therefore, a plurality of mats having a small size are often used in combination with connecting members.

  However, when combining with connecting members, there is room for improvement, such as it takes time for connecting work or it is difficult to remove and disassemble the connecting member from the mat once connected.

  Therefore, the present invention has been made in view of the problems in the conventional perforated rubber mat, and when performing a connecting operation or a disassembling operation when using a plurality of perforated rubber mats in combination using a connecting member. The purpose is to improve the workability.

  In order to achieve the above object, a perforated rubber mat according to the present invention connects a plurality of rubber mat members having a plurality of through holes penetrating in the thickness direction and adjacent mat members of the plurality of mat members. Each of the adjacent mat members including a plurality of connecting portions formed so as to extend in one direction and a connecting portion that connects the connecting portions to each other. The adjacent mat members are connected to each other by inserting the connecting portion through the through hole.

  Here, the rubber is a general term for natural rubber and synthetic rubber. Natural rubber refers to a solidified and processed rubber tree sap. Synthetic rubber refers to a synthetic polymer compound having properties similar to natural rubber, such as rubber elasticity at room temperature. For example, polyisoprene rubber obtained by polymerizing isoprene, styrene butadiene obtained by copolymerizing styrene and butadiene. Examples thereof include rubber and chloroprene rubber obtained by rubber-like polymerization of chloroprene.

  The resin is a generic name for natural resins and synthetic resins. The natural resin means a liquid that is secreted from the trunk and has been solidified by contact with air and losing volatile components. Synthetic resins refer to synthetic polymer compounds having properties similar to natural resins such as light and hard, and examples thereof include polystyrene, polyvinyl acetate, polyethylene, polypropylene, polyvinyl chloride, and polyethylene terephthalate.

  According to the present invention, since the soft mat member made of rubber is connected by the hard connecting member made of resin, the connecting member can be easily attached to the mat member, and the connecting operation and the disassembling operation can be easily performed. Workability is improved. Further, by connecting the connecting members to the originally provided through holes of the mat members, the mat members can be connected to each other using the connecting members without specially processing the mat members.

  Further, the connecting portion of the connecting member is formed into a truncated cone-shaped tapered portion whose outer diameter gradually increases from the insertion side end portion to the through hole of the mat member toward the other end portion, and the maximum diameter portion of the tapered portion. A cylindrical portion that is continuous and has an outer diameter smaller than the maximum diameter portion. Thereby, the mat member can be easily connected in a stable state by inserting the taper portion of the connecting portion into the through hole of the mat member and fastening it.

  Further, the connecting portion may be provided with a notch in the tapered portion and the cylindrical portion along the insertion direction, and the connecting member is matted by reducing the diameter of the connecting portion using the notch. Can be easily removed.

  As described above, according to the present invention, there is provided a perforated rubber mat that can be easily connected and disassembled, has good workability, and can easily connect mat members in a stable state. be able to.

  Next, modes for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 shows a mat member 1 constituting a perforated rubber mat according to the present invention. This mat member 1 is made of rubber, and has a base 2, a large diameter through hole 3, a small diameter through hole 4, and a ground. And a large number of protrusions 5 provided on the contacting surface. For example, the mat member 1 is formed in a square shape having a side of about 300 to 400 mm when viewed from above.

  The large-diameter through-hole 3 and the small-diameter through-hole 4 are provided for enhancing the anti-slip function on the upper surface side of the mat member 1 and for water permeability and weight reduction. The dimensions of these through-holes 3 and 4 are appropriately determined according to the purpose and place where the mat member 1 is installed. For example, the large-diameter through-hole 3 has a diameter of 30 mm and the small-diameter through-hole 4 has a diameter of about 15 mm. It can be. The large-diameter through hole 3 is also used when connecting a plurality of mat members 1 as described later.

  A large number of protrusions 5 are provided in order to exhibit an anti-slip function with the ground, and the height and diameter of the protrusions 5 are appropriately determined according to the purpose and place of the mat member 1.

  FIG. 2 shows a connecting member 11 for connecting the mat member 1. The connecting member 11 is formed of resin as a whole and is inserted into and fixed to the large-diameter through hole 3 of the mat member 1. The part 12 (12A-12D) and the plate-shaped connection part 13 which each connects these connection parts 12 (12A-12D) are provided. Each of the connecting portions 12 (12A to 12D) includes a truncated cone-shaped tapered portion 12a having an outer diameter gradually increasing from an insertion-side end portion to the large-diameter through hole 3 of the mat member 1 toward the other end portion, and a tapered portion 12a.
