The present invention relates to a fence structure, and more particularly to a fence featuring a convenient assembling process, saving time and labor, and preventing the outer surface of vertical and horizontal pipes from being scratched when the vertical and horizontal pipes touch or hit each other in the process of adjusting the angle of the fence.
As disclosed in U.S. Pat. No. 7,384,025 (hereinafter referred to as “D1”) issued to the inventor of the present invention, a horizontal pipe and a vertical pipe are connected with each other by a screw hidden device, and the D1 is characterized in that a positioning strip is installed in the horizontal pipe, and each horizontal pipe hides each screw and each positioning strip to beautify the appearance of the fence structure. In another U.S. Pat. No. 9,404,283 (hereinafter referred to as “D2”) entitled “Fence structure” and issued to the inventor of the present invention, the fence structure of the D2 comprises a plurality of horizontal pipes 13 and a plurality of vertical pipes 10 intersected with each other, and a plurality of horizontal connecting boards 11 horizontally disposed on a side of the vertical pipes 10 and also on the inner side of the horizontal pipes 13 for supporting the horizontal pipe 13 on the vertical pipe 10.
However, the application of D1 and D2 still has the following drawbacks and requires further improvements.
1. Since there is a notch at the bottom of the horizontal pipe, the peripheral surface of the horizontal pipe is incomplete.
2. When the fence is assembled, it is necessary to assemble the vertical pipes with the horizontal pipes one by one with a space apart from each other and to insert the vertical pipes into the corresponding holes respectively, so that the assembling process takes much time and effort.
3. When the angle of installing the fence is adjusted, the intersection angle between the horizontal and vertical pipes is changed. When such angle is adjusted to its limit, the pipe wall of the vertical pipe touches the hole of the horizontal pipe, and the pipe wall of the vertical pipe will touch the hole wall of the hole of the horizontal pipe, and the pipe wall of the vertical pipe will be rubbed to produce a scratch or a paint chip or damage the surface of the vertical pipe.
Therefore, it is a primary objective of the present invention to provide a fence structure capable of maintaining the integrity of the peripheral surface of the horizontal pipes, reducing the time and labor of the assembling process, and preventing the vertical pipes and horizontal pipes from hitting each other or scratching their outer surfaces when the angle of the pipes is adjusted.
To achieve the aforementioned and other objectives, the present invention discloses a fence structure characterized in that a connecting board is disposed in the horizontal pipe for supporting the horizontal pipe and pivoting the vertical pipes, and a plane is extended from the top of the connecting board towards the vertical pipe, and the plane has an embedded opening configured to be corresponsive to the vertical pipe for embedding the vertical pipe. A protective flange is protruded from each of two corresponding sides of the embedded opening and attached onto the horizontal pipe for passing the vertical pipe through an inner wall of a hole, and the protective flange is installed at a position in the same direction as the displacing direction of the vertical pipe when the angle of the vertical pipe is adjusted. The protective flange is provided, and the connecting board is made of a protective material (such as plastic), so that when the angle of the vertical pipe (or horizontal pipe) is adjusted, the inner wall of the hole is limited and protected and will not be in contact with the vertical pipe outer wall, so as to prevent the pipe wall of the vertical pipe from hitting the wall of the hole of the horizontal pipe or scratching the surface of the vertical pipe.
The present invention is also characterized in that the horizontal pipe is comprised of a main body having an opening on a longitudinal side and a cover disposed at the position of the opening and coupled to the main body. Both of the top and bottom of the main body have a plurality of corresponding holes (upper holes and lower holes), and the holes have an open opening formed at an end facing the opening, so that when the horizontal pipes and the vertical pipes are assembled, the vertical pipes are embedded into the hole of the main body through the hole opening, and then the cover is combined with the main body. The invention improves the conventional fence that passes the vertical pipes into the holes of the horizontal pipes one by one respectively and reduces the time and labor of assembling the fence.
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.
With reference to
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.
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.
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
With reference to
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.
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.
In
In summation, the present invention has the following advantages and effects:
1. The time and labor for assembling the fence 1 are reduced.
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.
3. The integrity of the peripheral wall of the horizontal pipe 20 can be maintained.
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.
