Abstract

An assembly type rubber mat for walking or the like that is easy to install and remove.
As a unit of an assembly-type rubber mat, a square rubber plate having a thickness of one third of the length and thickness of each of two adjacent sides of a square rubber plate having a predetermined thickness and size. The projection 2 in the shape of the horizontal direction is provided, and two projections 2 in the shape of two truncated cones are provided at left and right symmetrical positions on the lower surface of each projection piece 1. When the recess 3 is provided in the rubber plate from the center position of each opposing side of the side, and the protruding piece 1 is fitted into the recess 3 from the lateral direction so that the upper and lower surfaces are adjacent to each other with the square rubber plates, The concave portion 3 is formed so that the protruding piece 1 is fitted to the concave portion 3 and the projection 2 of the protruding piece 1 reaches the lower surface of the rubber plate, and each of the protruding piece 1 and the concave portion 3 is formed on one square rubber plate. And the lower side of the entrance of the recess 3 is expanded downward.

Description

  The present invention relates to an assembly-type rubber mat for walking at construction sites, etc., which may be laid on rough road surfaces at outdoor events, etc., or laid on a school poolside to prevent falls. is there.

  Conventionally, in order to ensure safety at construction sites, etc., belt-shaped synthetic resin sheets and rubber mats are often laid for general pedestrian walkways. These operations are not easy, labor-intensive, bulky in storage, not easy to handle, and improvements are desired in installation, removal, maintenance and inspection.

On the other hand, as patent information, Patent Document 1 has a rubber additive-containing rubber mat having an anti-icing effect, and the liquid additive exudes on the surface of the rubber mat to form a film to prevent and peel off the icing. . Japanese Patent Laid-Open No. 2004-26883 discloses a pedestrian floor structure in which two layers having different elastic coefficients are provided, and the position is guided to the visually handicapped person with the feeling of the sole of the foot. Patent Document 3 proposes an anti-slip rubber mat, which has a drainage groove and an elastic protrusion on the surface, and breaks the frozen layer by elastic deformation of the elastic protrusion to obtain an anti-slip effect. Patent Document 4 has a rubber mat in which a rubber composition and a polyurethane resin are integrated, and is used by covering a road surface. Patent Document 5 discloses a mat-like rolling element for temporary restoration that is laid after the road is backfilled, but nothing relating to the shape or combination of rubber mats is found.

  The present invention is intended to provide a unit of a rubber mat for assembly that is easy to install and remove.

  Here, the present inventor, as a unit of an assembly type rubber mat, has a thickness of one third of the rubber plate at the center of the length and thickness of each of the two adjacent sides of a square rubber plate of a predetermined thickness and size. The projections 1 in the horizontal direction in the shape of a square are provided, and two projections 2 in the shape of two truncated cones are provided at left and right symmetrical positions on the lower surface of each projection piece 1. A recess 3 is provided in the rubber plate from the center position of each of the two opposing sides, and the projecting piece (1) is formed from the lateral direction to the recess 3 so that the square rubber plates are adjacent to each other and the upper and lower surfaces coincide with each other. When inserted, the recess 3 is formed so that the protrusion 1 fits into the recess 3 and the protrusion 2 of the protrusion 1 reaches the lower surface of the rubber plate, and the protrusion 1 and the recess are formed on one square rubber plate. 2 of each 3 existed, and a thing consisting of expanding the lower side of the entrance of the recess 3 downward was found.

  The reason why the lower side of the entrance of the recess 3 is expanded downward is to facilitate insertion of the protruding piece 1 and to facilitate insertion of a finger during disassembly.

  In order to construct the assembly type rubber mat, the protruding piece 1 of the square rubber plate as one unit of the assembly type rubber mat is fitted and connected to the recess 3 of the square rubber plate as one unit of the assembly type rubber mat. Thus, an assembly type rubber mat having a predetermined shape can be obtained.

  When the assembly type rubber mat of the present invention is removed and stored, the finger of the hand is inserted into the recess 3 of one unit of the used rubber mat and is pushed down slightly to pull it out, so that the protruding piece 1 is removed from the rubber mat.

  The assembly type rubber mat of the present invention is easy to install and remove, has good stability at the time of installation, and is not bulky at the time of storage.

  The assembly type rubber mat of the present invention is characterized in that the protruding pieces 1 appear on the two sides of the periphery in a configured state, but this does not hinder practical use. See FIG. Specific examples are described in the following examples.

  As a unit of the assembly type rubber mat, the protruding piece 1 has a square of 50 × 150 mm, and the protrusion 2 has a diameter of 20 mm at the bottom and a diameter of 14 mm at the top with respect to a square rubber mat having a side of 500 mm and a thickness of 15 mm. One unit of the rubber mat uses rubber that is hard to some extent, and can be easily molded by a mold.

  The assembly type rubber mat of the present invention is not only sufficiently effective, but also easy to install and remove, is not bulky for storage, and is easy to transport.

Claims (1)

  A horizontal protruding piece (1) in the shape of a square of a third thickness of the rubber plate at the center of the length and thickness of each of the two adjacent sides of a square rubber plate of a predetermined thickness and size The projections (2) having the shape of two truncated cones are provided in the left and right symmetrical positions of the lower surface of each projection piece (1), and each of the two sides having the projection piece (1) is opposed to each other. A recess (3) is provided in the rubber plate from the center position of the side, and the protruding piece (1) is inserted into the recess (3) from the side so that the square rubber plates are adjacent to each other and the upper and lower surfaces coincide. In this case, the recess (3) is formed so that the projecting piece (1) fits into the recess (3) and the projection (2) of the projecting piece (1) reaches the lower surface of the rubber plate. One unit of an assembling-type rubber mat having two protruding pieces (1) and two concave portions (3) on the rubber plate, and the lower side of the inlet of the concave portion (3) is expanded downward.
