DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0014]
As shown in FIGS. 1 to 6, the approach protection fence of this embodiment is a car stop pole having a fence portion 1 that protrudes on the ground in order to separate a human area and a car area and prevent a car from entering. Yes. With this entry guard, the vehicle is normally prevented from entering, and the vehicle is allowed to pass only when necessary.
[0015]
As shown in FIG. 2, this approach protection fence (car retaining pole) includes a stainless steel fence portion 1 that protrudes on the ground, and a stainless steel sheath that is disposed in the ground to cover the fence portion 1. A pipe 2, a stainless steel guide ring 3 laid downward from the ground surface (GL, FL) and through which the fence part 1 is inserted, and a stainless steel fixing cylinder part for positioning the sheath pipe 2 to the guide ring 3 4 and a stainless steel decorative plate 5 on the ground surface through which the fence portion 1 is inserted and covers the guide ring 3. Between the sheath tube 2 and the fence portion 1, a guide tube portion (bush) 6 made of ABS resin is interposed. The decorative plate 5 on the ground surface is provided with a stainless steel shell lid 7 (almost flush with the ground surface when closed).
[0016]
The stainless steel guide ring 3 has an edge 8 standing on its outer periphery. The height of the edge 8 is set corresponding to the depth at which the guide ring 3 is laid on the ground surface (GL, FL). The stainless steel fixing cylinder part 4 is composed of a cylindrical part 9 and a fixing collar part 10 extending to the cylindrical part 9. The decorative plate 5 passes through the guide ring 3 and is fixed to the ground by a countersunk screw 11.
[0017]
The fence portion 1 is supported by the anchor bolt 12 of the sheath tube 2 and protrudes to the ground. The fence portion 1 has a stainless steel crane 13 at the top of the fence portion 1 so as to perform the collection / removal work into the ground. As shown in FIG. 4, the position at which the fence portion 1 is retracted into the ground is indicated by “open” and “closed” of the mark portion 14.
