The plastic fence of the present invention (hereinafter referred to as
Simply called a fence. The leg part of) is attached to the lower end of the column to obtain stability of installation of the fence, and is formed in a hollow shape, and if necessary, a weight such as a stone is put in the hollow part for use. This leg is usually attached to the column at right angles to the fence, but depending on the installation surface,
The structure may be such that the mounting direction can be changed. The cross-sectional shape of the legs, if the shape of the fence stability can be obtained,
Any shape such as a square pole, a cylinder, a triangle pole, and a polygonal pole may be adopted. The legs are usually mounted with the stanchions in the center of the legs for stability.

Further, it is preferable that the legs are formed to have an appropriate size from the viewpoint of the appearance of the fence as a whole from the viewpoint of balance and prevention of falling, and the length of the legs is equal to the height of the column. It is preferable to form it in a size of 0.35 to 0.6 times.

Each constituent member of the fence of the present invention is formed of plastic, and particularly preferably, a thermoplastic resin is formed by extrusion molding or injection molding. As the moldable thermoplastic resin that can be used for the fence of the present invention, polyvinyl chloride, polystyrene polycarbonate,
Polypropylene, polyethylene, ABS and the like,
Additives such as stabilizers and modifiers are added to these resins depending on the application such as outdoor use. Furthermore, in order to enhance the design of the fence, white etc. according to the purpose of use,
It is preferable to give arbitrary coloring.

Further, the constituent members of the fence of the present invention are usually pellets or powder of a thermoplastic resin supplied to an extruder hopper, and under normal extrusion conditions of each resin, a pillar having a hollow structure, a furring strip, and a panel. Mold the legs separately. Each component coming out of the die is cooled and sized in a vacuum sizing water tank, etc., and then taken by a caterpillar take-off machine etc., cut and made into a certain size, and then the furring is inserted as a secondary process. A hole is formed in the column and a hole for inserting the panel is formed at a predetermined position on the furring strip. Further, each extruded constituent member may be extruded into two layers by using two kinds of resins such as a base resin and a surface layer resin in addition to a single layer extruded from a single resin, Furthermore, two or more kinds of resins may be used to perform multi-layer extrusion of two or more layers.

An example of the fence of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the fence of the present invention is composed of a pillar 1, a furring strip 2, a panel 3, a pillar lid 4, and a leg portion 5 attached to a lower end portion of the pillar.
