Fence

Abstract

This invention offers a fence, comprising vertical tubes, horizontal tubes joined with the vertical tubes, and integrated connectors for the join of the vertical tube and the horizontal tube. The interior of the horizontal tube is divided into an axial through hole and an axial embedded trough. An indented axial guiding notch is provided on the corresponding location of each interior wall of the embedded trough. The vertical tube is divided with a plurality of axial tube chambers. The integrated connector is made up of an insert piece and a slide piece, where both can be connected either in single-point pivot connection or into a single piece. The slide piece is provided with a protruded guiding bar corresponding to the guiding notch of the embedded trough. The single-piece type of the integrated connector will suit for the landforms where the vertical tube and the horizontal tube are perpendicular to each other.

1 . A fence, comprising a plurality of vertical tubes, at least two horizontal tubes for the join with the vertical tubes, at least two side posts for the fixing of both ends of the horizontal tube, and a plurality of integrated connectors for the join of the vertical tube and the horizontal tube; wherein,
 1.) horizontal tubes, having an axial embedded trough separated from its interior, which has an opening at the side facing the end of the vertical tube, and the width of the opening being wider than that of the vertical tube, where an indented axial guiding notch is provided on the corresponding location of each interior wall of the embedded trough;   2.) vertical tubes, having axial tube chambers therein;   3.) integrated connectors, where each is made up of an insert piece and a slide piece, and the slide piece being provided with a protruded guiding bar at the location of each side corresponding to that of the guiding notch of the embedded trough, which enables the slide piece to be placed in the embedded trough and its guiding bars in the guiding notch to avoid the slide piece fallen down from the embedded trough; the insert piece, having embedded chunks protruded facing the openings of the tube chambers of the vertical tube, where the embedded chunks are inserted into the tube chambers of the vertical tube respectively for a fixing.   
     
     
         2 . A fence as recited in  claim 1  wherein the insert piece and the slide piece of the integrated connector are in single-point pivot connection. 
     
     
         3 . A fence as recited in  claim 1  wherein the insert piece and the slide piece of the integrated connector are shaped into a single piece. 
     
     
         4 . A fence as recited in  claim 2  wherein the integrated connector made up of the insert piece and the slide piece is a single-point pivot connection structure, where the slide piece is provided with a protruded extension on each side facing the insert piece, and a pivot hole being devised at the center of each extension, while the insert piece joining the slide piece at the location between the two extensions of the slide piece, followed by the pivot connection with the insert piece through using a fastening piece to pierce through the pivot hole. 
     
     
         5 . A fence as recited in  claim 1  wherein the insert piece of the integrated connector is inserted into the vertical tube and both being fastened by a bolt. 
     
     
         6 . A fence as recited in  claim 1  wherein the interior of the horizontal tube is provided with an axial through hole, where the through hole is provided for the accommodation of an inner tube that enables the outside horizontal tube to be sustained by the inner tube, and both ends of the inner tube being fixed to the side posts.
