Fencing system

Abstract

This invention provides a fencing system (10) comprising a plurality of spaced apart parallel extending upright posts (12); a plurality of horizontally extending bearers (14); and a plurality of parallel extending uprights (16). First connecting means (18) connects the bearers (14) to the posts (12) and second connecting means (20) connects the uprights (16) to the bearers (14). Each post (12) defines an elongate channel 12.1, and is provided with a cover 12.2 connected to the post (12) by a fourth connecting means (22), for closing the channel 12.1. Posts (12) located in a central region of the fencing system (10) are adapted to receive a supporting insulator (24), for supporting an electrified conductor (26). A carrier (28) is connected to corner posts (12) by third connecting means and includes a carrier (28) with connecting formations 28.2 for connecting to an insulator (30) for carrying electrified conductors (26).

Description

INTRODUCTION AND BACKGROUND TO THE INVENTION [0001] This invention relates to a fencing system. [0002] South African patent number 99 / 0156 discloses a method of joining an upright to a bearer. Both the upright and the bearer are of channel sections and comprise a web with a flange along each edge of the web, the flanges diverging from one another in the direction away from the web. This method includes the steps of forming two spaced slots in the bearer, the slots being at an angle with respect to one another, forcing said flanges of said upright towards one another to decrease the size of the gap between them, inserting the flanges into said slots and releasing the flanges so that they spring apart. [0003] A disadvantage of the above fence is that, owing to the configuration of the connection, the upright is relatively easily removed from the bearer. [0004] South African patent number 2000 / 0700 discloses a method of constructing a fence. This method includes the steps of erecting a...

Benefits of technology

[0008] It is therefore an object of the present invention to provide a fencing system with which the aforesaid disadvantages can be overcome or at least minimised, and to provide a useful alternative to the known fences. SUMMARY OF THE INVENTION

[0019] Further according to the invention, the male formation is provided with a resilient portion extending out of its plane for providing a clip lock, the arrangement being such that the portion is forced into the plane when the planar spigot is inserted into the slot and further such that the resilient portion deforms out of the plane after insertion, to restrict withdrawal of the male formation.

Problems solved by technology

A disadvantage of the above fence is that, owing to the configuration of the connection, the upright is relatively easily removed from the bearer.

A disadvantage of the above fencing system is that the use of separate locking clips is cumbersome in that one has to ensure that an equal amount of clips and uprights are provided at the erection site, and if one of the clips should be damaged, a shortage of clips is experienced at the site.

One of the disadvantages of the above fence is that it is relatively expensive to manufacture as the amount of material and machining required to manufacture the horizontal bearers are excessive.
