BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a furring strip for fence and a fence.
BACKGROUND ART
A fence is provided with furring strips for supporting and strengthening a fence body, by which a fence is usually strengthened and joined to a support.
A conventional furring strip is made of a pipe or the like, which is heavy in weight and presents heavy external appearance while it is strong. The furring strip is subject to wind pressure and snow weight, which causes in a strong wind area or a snowfall area disadvantage in strength. Further the furring strip cannot be easily cut on the spot the fence is built.
An object of the invention is to improve said disadvantage of the conventional art and to provide a furring strip which is light in weight, looks light, has little resistance to wind and is not subject to snow weight.
Another object is to provide a fence, which is light in weight, strong and has good outside appearance.
DISCLOSURE OF INVENTION
In order to accomplish said objects, the furring strip of the invention is characterized in comprising a bent wire rod which is bent alternately in opposite directions at predetermined intervals and a pair of parallel wire rods extending in a longitudinal direction which is provided with said bent wire at the front and the back sides.
Thus the furring strip of the invention is light in weight and tends not to be affected by wind and snow. It looks light as well. Further, the bent wire rod creates strength in a lateral direction and the parallel wire rods provide strength in a thickness direction, that causes large strength of the fence while being light in weight. Moreover the construction at the scene is easy, because processing steps, such as cutting the wire rods is easy.
The top of the bent wire rod preferably projects from the parallel wire rod so as to make welding work easy.
Though the furring strip of the invention may be adapted to many types of fence, it is most appropriately applied to a wire lattice fence, more preferably, to a fence where lateral wire rods are bent so as to form a folding screen-like-shape. It is hoped to locate the furring strip so as to make the locations of both tops of the bent lateral wire rods and said bent wire rod coincident. Such construction provides a fence with a nice appearance and larger strength. It is easy to set a plurality of the fences in steps.

BEST MODE OF CARRYING OUT THE INVENTION
An embodiment of the invention will be explained hereafter referring to drawings.
FIG. 1 is a plan view of a furring strip A of the invention, which comprises a bent wire rod 1, with a total of successively bent in a triangle form and a pair of parallel wire rods 2.
The parallel wire rods 2 are secured on both the front and back sides of the bent wire rod 1, with a total of four parallel wire rods 2 used there.
The parallel wire rods 2 are so set that a top 10 of the bent wire rod 1 projects a little over the outside of the pair of parallel wire rods 2.
This construction is to make welding the bent wire rod 1 and the parallel wire rods 2 eas
