Description

  The present invention relates to a vehicle stopping technique for blocking an approach path of a vehicle with a wire and a blocking visual recognition tool.

Japanese Utility Model Laid-Open No. 4-41513 (Patent Document 1) and Japanese Patent Application Laid-Open No. 10-204838 (Patent Document 2) have been proposed to enable the chain to be extended and stored from the inside of the column main body in the car stopper. Yes. The technique disclosed in the former Patent Document 1 hangs a wire 7 wound around a fixed pulley assembly 10 corresponding to a fixed pulley around a movable pulley assembly 14 corresponding to a moving pulley, and further passes the tip of the wire 7 to the chain wheel 3. The drum 6 is fixed to the drum 6 that rotates integrally, and has a complicated structure in which two fixed pulleys are incorporated. In addition, there is a waste of operating elements such as the use of a wire for feeding and storing the chain 5, and this mechanism cannot use a general wire in place of the chain 5. Furthermore, since the movable pulley assembly 14 is operated by the elastic force of the tension coil spring 15, the feeding force is increased at the extended end of the chain 5, and the operating force is varied such that the storage force is weakened at the storage end.
The technique disclosed in the latter patent document 2 wraps the wire 2 connected to the chain 14 around the fixed pulley 4, and the tip of the wire 2 wound around the moving pulley 7 is above the rising end of the moving pulley 7. A step lever 9 which is locked to the inner wall of the pole 1 and fixed to the lower surface of the guide frame 8 which rotates and holds the movable pulley 7 protrudes outward from the pole 1, and the chain 14 is lowered by stepping on the step lever 9 with a foot. Install. In this structure, the chain 14 cannot be housed inside the pole 1, and therefore the chain 14 remains on the road when the vehicle entry path is unblocked. Depending on the vehicle entry condition, an unnecessary external force may be applied to the chain 14. May cause the pole 1 to be pulled over. In addition, a warning element such as a sign or a visual check tool at the time of blocking cannot be attached because it is crushed by the vehicle and dirty when placed on the ground.
