Fence structure

Abstract

A fence structure has a plane extended from the top of a connecting board to a vertical pipe and an embedded opening formed at corresponding position for embedding the vertical pipe. A protective flange is protruded from each of two corresponding sides of the embedded opening, attached onto a horizontal pipe for passing the vertical pipe to an inner wall of a hole, and installed at a position in the same displacing direction when the angle of the vertical pipe is adjusted. The horizontal pipe is formed by a main body with an opening on the longitudinal side and a cover disposed at the opening position and coupled to the main body. While adjusting the angle of the fence, the vertical and horizontal pipes are prevented from hitting each other or scratching their outer surfaces. In addition, the time and labor of assembling the fence can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(14) The technical characteristics, contents, advantages and effects of the present invention will be apparent with the detailed description of a preferred embodiment accompanied with related drawings as follows.

(15) With reference to FIGS. 13 for a fence of the present invention, the fence 1 comprises a plurality of vertical pipes 10, a plurality of horizontal pipes 20 and plurality of connecting members 30. Wherein, the vertical pipes 10 and the horizontal pipes 20 are passed and intersected with each other; the connecting members 30 are disposed in the horizontal pipe 20 and pivoted with an outer wall of the vertical pipe 10 to provide the effect of supporting and fixing the horizontal pipe 20 and prevent the horizontal pipe 20 from sliding away from the predetermined installation position.

(16) Wherein, the vertical pipe 10 is in a tubular shape, and the pipe wall of each of the horizontal pipes 20 has a radial pivot hole 11 at the intersection position.

(17) The horizontal pipe 20 is comprised of a main body 21 and a cover 22. The main body 21 is hollow and has an opening 210 formed on a longitudinal side, and a blocking flange 211 configured to be corresponsive to the upper and lower opening edges of the opening 210 and extended towards the interior of the opening 210. Both of the top and bottom of the main body 21 have an upper hole 212a and a lower hole 212b formed thereon and configured to be corresponsive to the installation positions of each vertical pipe 10 respectively, and the upper and lower holes 212a, 212b are aligned precisely in the vertically up-and-down direction, and have a hole opening 213a, 213b facing an end of the opening 210. The cover 22 is installed at a position of the opening 210 of the main body 21 and provided for covering the opening 210; each of the upper and lower ends of the cover 22 has a hook 220 extending into the opening 210, and the extending end of the hook 220 has an inclined guiding side 221, so that when the cover 22 and the main body 21 are combined, the guiding side 221 is provided for sliding the blocking flange 211, so that the hook 220 can be latched and positioned with the blocking flange 211 accordingly to cover the opening 210. The blocking flange 211 and the hook 220 constitute a binding device for combining the main body 21 and the cover 22 to form a horizontal pipe 20.

(18) The connecting board 30 is inverted L-shaped and has a straight side 31 and a plane 32 horizontally extended from the top of the straight side 31. An abdominal portion of the straight side 31 has a pivot shaft 310 horizontally extending towards the bottom of the plane 32 (as shown in FIGS. 4 and 10), and a positioning ring 311 is protruded from a middle section of the pivot shaft 310, and the connecting board 30 has a clip wall 312 horizontally extended from the abdominal portion of the straight side 31 towards the bottom of the plane 32, and a horizontal gap D is formed between an extending end 3120 of the clip wall 312 and the positioning ring 311 (as shown in FIG. 10), and the horizontal gap D has a size equal to the unilateral thickness of the vertical pipe 10, so that after the pivot shaft 310 and the positioning ring 311 are passed into the pivot hole 11, the extending end 3120 of the clip wall 312 and the positioning ring 311 can attach and fix the outer wall on a side of the vertical pipe 10 to the inner wall, so as to pivot the connecting board 30 to an outer wall of the vertical pipe 10. The plane 32 has an embedded opening 320 formed at a position corresponsive to the position of the upper and lower holes 212a, 212b, and the embedded opening 320 has an open opening facing an end of the vertical pipe 10, and a protective flange 321 is protruded from each of two corresponding sides. After the connecting board 30 and the horizontal pipe 20 are combined, the protective flange 321 is attached to the interior of the upper hole 212 of the horizontal pipe 20 and also attached to the hole wall of the upper hole 212, and the protective flange 321 is installed at a position in the same direction as the displacing direction of the vertical pipe 10 when the angle of the vertical pipe 10 is adjusted. With the protective flange 321 and the connecting board 30 made of a protective material (such as plastic) for preventing the metal pipes from being scratched, so that when the angle of the vertical pipe 10 (or horizontal pipe 20) is adjusted, the inner wall of the upper hole 212 will be protected and limited by the protective flange 321, and the outer wall of the vertical pipe 10 will not be rubbed, so as to prevent the vertical pipes and horizontal pipes 10, 20 from hitting each other or scratching the surface of the pipes.

(19) With reference to FIGS. 510 for the process of assembling the fence 1, the assembling process comprises the following steps:

(20) Step 1: Embed a connecting board 30 into the respective position of the upper and lower holes 212a, 212b of the main body 21 of each horizontal pipe 20, so that the protective flange 321 of the connecting board 30 is situated in the upper hole 212a and attached onto a hole wall of the upper hole 212a.

(21) Step 2. Embed a vertical pipe 10 into the respective position of the upper and lower holes 212a, 212b of the main body 21 (as formed after Step 1), and the pivot shaft 310 of the connecting board 30 into the respective pivot hole 11 of the vertical pipe 10, and then slide the connecting board 30 through the blocking flange 211 by the guiding side 221 of the hook 220 of the binding device, so that the hook 220 is latched and fixed to the blocking flange 211 accordingly to cover the opening 210 of the main body 21 and maintain the integrity of the peripheral pipe wall of the horizontal pipe 20.

(22) In FIGS. 1113, when the angle of the pipes of the fence 1 is adjusted, the vertical pipe 10 may be adjusted by shifting the axis to the left or right by the pivot shaft 310. Regardless of the vertical pipe 10 shifting all the way to the right (as shown in FIG. 12), or all the way to the left (as shown in FIG. 13), the vertical pipe 10 will be limited and protected by the protective flange 321, so that the outer wall of the vertical pipe 10 will not rub with the hole wall of the upper and lower holes 212a, 212b of the horizontal pipe 20 to prevent the pipe wall of the vertical pipe 10 from being scratched.

(23) In summation, the present invention has the following advantages and effects:

(24) 1. The time and labor for assembling the fence 1 are reduced.

(25) 2. When the angle of the pipes of the fence 1 is adjusted, the pipe wall of the vertical pipe 10 and the hole wall of the horizontal pipe 20 can be prevented from being scratched.

(26) 3. The integrity of the peripheral wall of the horizontal pipe 20 can be maintained.

(27) In summation of the above description, the present invention herein enhances the performance than the conventional structure and further complies with the patent application requirements and is submitted for patent application. While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
