Embodiment Construction

[0018]As shown in FIGS. 1 and 2, a first preferred embodiment of a fence in the present invention consists of an upper fence 1 and a lower fence 2, and a connecting member 3 linking the upper fence 1 with the lower fence 2. The connecting member 3 is composed of an upper fastening bar 30, a lower fastening bar 31, a connecting tube 32 and a connecting pin 33.

[0019]The upper fastening bar 30, as shown in FIGS. 3 and 3B, is formed as a straight strip, transversely positioned on the lower sidewall of each post 10 of the upper fence 1 by being sideward fastened by a screw 300 to keep the bottom of the post 10 of the upper fence 1 connected, and having a pushing-and-pulling surface formed on its top.

[0020]The lower fastening bar 31, as shown in FIG. 2 and FIG. 3C, is also formed as a straight strip, transversely positioned on the upper sidewall of each post 20 of the lower fence 2 by being fastened by a screw 310 to keep each of the posts 20 connected. Also, the upper fastening bar 30 an...

Abstract

A fence has a connecting member to join an upper fence and a lower fence together. The connecting member consists of an upper fastening bar transversely positioned on the bottom of each post of the up per fence, a lower fastening bar also transversely positioned on the top of each post of the lower fence, and a connecting tube that is cut with an inserting groove in its bottom and plural holes bored on its top respectively for each post of the upper fence to insert. Two positioning segments are formed inside the connecting tube to respectively fix with the upper fastening bar and the lower fastening bar. A connecting pin has its two ends respectively inserted into each post of the upper fence and also each post of the lower fence to keep the two posts joined together. Thus, the fence can be easily assembled and raised with its height without discarding original posts.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to a fence, particularly to one having its screws invisibly installed, and its upper fence and its lower fence conveniently assembled together.[0003]2. Description of the Prior Art[0004]Commonly, a conventional fence or the like made of metal is composed of plural rails (at least an upper one and a lower one), and plural posts cross-linked with the rails. Each intersection of the rails and the posts is fastened by a screw. But, if the fence is to be heightened, it is always done either by replacing the posts with longer ones, posing a high cost, or by being welded with additional posts, possible to smear the fence.SUMMARY OF THE INVENTION[0005]The objective of this invention is to offer a fence able to be easily assembled and raised with height.BRIEF DESCRIPTION OF DRAWINGS[0006]This invention is better understood by referring to the accompanying drawings, wherein:[0007]FIG. 1 is a planar view of ...
