POLE ASSEMBLY

Abstract

A pole assembly includes four supporting poles spaced from one another, two rails each supported on two adjacent supporting poles, and a mounting apparatus. Each of the supporting poles includes a fastener. Each fastener includes a locking portion and two connecting portions. The rails are in a row and positioned at a same height of the supporting poles. Each rail defines two locking slots adjacent to opposite ends of the rail. Each locking slot includes an opening and a locking hole communicating with the opening. Each rail is set on two adjacent supporting poles. The connecting portions engage in the corresponding locking holes. The adjacent ends of two adjacent rails are fixed to the mounting apparatus.

Description

BACKGROUND

1. Technical Field

The present disclosure relates to poles and, particularly, to a pole assembly for supporting photovoltaic modules.

2. Description of Related Art

A supporting apparatus for photovoltaic modules may be made by welding a plurality of metal poles together with a non-flexible structure, which results in inconvenience in transportation of the supporting apparatus. Another type of supporting apparatus is assembled by a number of poles. The poles are connected to each other by screws. However, it may be time-consuming in assembling the poles with screws.

DETAILED DESCRIPTION

The disclosure, including the accompanying drawings in which like references indicate similar elements, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”

FIG. 1 shows an embodiment of a pole assembly. The pole assembly includes four supporting poles 10, a plurality of rails 20 supported on the supporting poles 10, and a plurality of mounting apparatus 30. The supporting poles 10 are parallel to one another and angled in relation to the ground. The rails 20 are parallel to one another and perpendicular to the supporting poles 10. Each rail 20 is supported by two adjacent supporting poles 10 and fixed to the same heights of the supporting poles 10. Each two rails 20 fixed to the same heights of the supporting poles 10 are connected by a mounting apparatus 30.

FIG. 2 to FIG. 4 show that each supporting pole 10 includes a plurality of fasteners 12 at different heights. Each fastener 12 is formed by stamping of the supporting pole 10. The fastener 12 includes a truncated cone shaped locking portion 122 and two connecting portions 123 extending from opposite sides of the locking portion 122 and connected to the tops of the supporting pole 10 respectively. The width of the locking portion 122 is greater than the width of the connecting portions 123.

Each rail 20 is U-shaped and includes a bottom wall 21 and two sidewalls 22 extending from opposite sides of the bottom wall 21. The bottom wall 21 defines two locking slots 211 in opposite ends of the bottom wall 21. The distance between the locking slots 211 is equal to a distance between two adjacent supporting poles 10. Each locking slot 211 includes an opening 2111, and two locking holes 2113 communicating with opposite sides of the opening 2111. The width of each locking hole 2113 is less than the width of the opening 2111. The sidewalls 22 define two opposite through holes 221 in each end of the rail 20.

Each mounting apparatus 30 includes a U-shaped connecting member 31 and a plurality of screws 33. The connecting member 31 includes two parallel side plates 311. The side plates 311 each define a plurality of mounting holes 312.

FIG. 5 shows that to mount the rails 20 to the supporting poles 10, each rail 20 is set on two adjacent supporting poles 10, with the locking slots 211 aligning with the fasteners 12. The locking portions 122 are inserted in the corresponding openings 2111. The rail 20 is then slid toward the corresponding mounting apparatus 30, to make the connecting portions 123 engage in the corresponding locking holes 2113 away from the mounting apparatus 30. The locking portions 122 block a top surface of the rail 20 surrounding the locking holes 2113. The adjacent ends of two rails 20, which are in a row and supported on same heights of the four supporting poles 10, are engaged in the corresponding connecting member 31 between the side plates 311. The screws 33 extend through the mounting holes 312 and the through holes 221 to fix the adjacent ends of the rails 20 to the connecting member 31. Thus, the two rails 20 are assembled on the supporting poles 10.

In one embodiment, the rails 20 are fixed to the supporting poles 10 through the fasteners 12 mating with the locking slots 211, which can reduce the quantity of screws being used. Furthermore, the position needed for screwing is changed to a space between two supporting poles 10 and not at a junction of the supporting pole 10 and the rails 20, which is easy to operate.

It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
