TH18967Y - Flexible traffic bollards - Google Patents

Abstract

This invention describes a flexible rubber traffic cone designed for installation on road surfaces. It serves as a lane control device, used for dividing lanes, separating traffic areas, or indicating intersections, thereby enhancing safety. These cones are commonly installed on roads and are hollow cylindrical in shape, based on the design specifications of Manual No. 4 (Manual for the Installation of Traffic Signs and Construction, Rehabilitation, and Maintenance of Expressway Department, 2018). The flexible traffic cone must have a minimum height of 70 centimeters and a minimum diameter of 7.5 centimeters. A new design has been developed, allowing for two different installation methods on road surfaces. A M20x80 mm bolt is installed at the center of the cone's base to secure it to a mounting device (anchor) embedded beneath the road surface. This new installation method reduces installation time and minimizes the risk of exposed nuts or screws that could cause tire blowouts and lead to accidents. The curved, bendable design allows for flexible installation of this rubber traffic cone. The new design features increased resistance and bending range compared to conventional collapsible traffic bollards, which reduces cracking from repeated compression and results in a longer lifespan and greater safety.

Claims (8)

1. Flexible traffic cone (100) consists of: the body of the cone (101) which is a hollow cylinder and serves as the body structure of the flexible traffic cone (100); the indentation (102) which is curved inward and serves as a connecting part, with one end connected to the body of the cone (101) and the other end connected to the base (103); the base (103) which is a cylinder with holes for fastening devices (104) and serves as a base to support the weight of the body of the cone (101) and the indentation (102); the fastening device (104) is a bolt and serves as a device for fastening to the road surface or inside the road; the groove (105) is a deep groove with at least 3 grooves around the body of the cone (101) and serves as a boundary for installing reflective strips, with a specific characteristic being that the base (103) has a hole in the middle on one side. It is a deep hole that extends 80-85 percent of the base (103), with the height of the base (103) being 4-8 percent of the length of the body (101), and the diameter of the base (103) being 80-100 percent of the diameter of the body (101). The aforementioned indentation (102) is axially symmetrical and has no holes. The height of the indentation point is 5-15 percent of the length of the body (101), and the size of the indentation point with the smallest value is 25-35 percent of the diameter of the body (101) for bending during assembly. 2. Flexible traffic posts according to claim 1, where the body (101) has an outer diameter of at least 7.5 centimeters and a height of at least 70 centimeters. 3. Orange traffic cone, according to claim 1 or 2, where the body (101) has an internal surface area that is sloped at an angle of 0.5-3 degrees from the top end to the bottom end. 4. Collapsible traffic posts under any of the claims 1 to 3, where the body (101) has a thickness of the top wall less than the bottom wall. 5. Flexible traffic posts according to any one of the claims 1 to 4, in which the body (101) has at least 2 holes at one end for drainage of water to the outside. 6. Flexible traffic bollards, according to any one of the claims 1 to 5, where the base (103) has a fastening device (104) protruding from the end area by at least 50 millimeters. 7. Flexible traffic bollards, as per any one of claims 1 through 6, where the rubber is rigid and retains its shape. 8. Flexible traffic bollards, as per any one of claims 1 through 7, where the rubber has a hardness of 50 plus or minus 3 Shore A.
