Benefits of technology

"The invention provides an improved way to construct pool fences by using a hollow rail and pickets that enter the rail through entry apertures and are fastened inside the rail using fastening means. The pickets can be fastened using rods or deformation of the rail. The fence can have one or two parallel rails and the pickets pass through or end within the rail. The internal structure of the rail can hold the pickets, and the pickets can be fastened using fastening means inside the rail or by deformation of the pickets. The invention also includes equipment for constructing panels for a fence or picket structure. The technical effects of the invention include improved construction of pool fences and better protection of pickets."

Problems solved by technology

Each panel typically has 20-30 pickets so the methods are generally slow with a significant cost of manual labor.
The need to paint the panel after the pickets have been fastened to the rails can also be a disadvantage.
Structural weaknesses are sometimes experienced in panels where the pickets do not extend beyond the top rail.
In these systems the top ends of the pickets lie within the top rail and can be difficult to fasten sufficiently strongly to the rail.

Embodiment Construction

[0037] Referring to the drawings it will be appreciated that the invention can be implemented in various ways for a range of different picket-like structures, such as pool fences, balustrades, ladders, walls and the like. This description of pool fence embodiments is given by way of example only.

[0038]FIG. 1 shows the main components of a panel for a pool fence including a bottom rail 10, mid rail 11, a top rail 12, a number of pickets 13, two posts 14, locking rods 15 and top pins 16, and bottom pins 17. These components may be provided in a wide range of numbers, shapes, and sizes, and may be assembled in different ways, depending on the purpose and style of the fence. The components are usually provided has hollow tubes or other sections of a metal such as aluminum or steel.

[0039]FIG. 2 shows how the panel may be assembled. The pickets 13 pass through pairs of apertures in the bottom and mid rails 10, 11 and in this example, enter but do not exit the top rail 12, which has aper...

Abstract

A fence construction system in which panels are formed by attaching pickets to rails using fastening means that is located inside the rails. In one system, the pickets are fastened to a rail by a common locking rod. In another system the pickets are deformed inside the rail by a crimping tool. Equipment that assists assembling the panels may be provided. Top or bottom rails may also have a support structure provided within the rail.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a division of U.S. application Ser. No. 10 / 549,772, filed Sep. 19, 2005, which is in turn a Section 371 of International Application No. PCT / AU2004 / 001791, filed Dec. 20, 2004, which was published in the English language on Oct. 12, 2006, under International Publication No. WO 2005059279. The disclosures of these applications are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] This invention relates to construction of fences, in particular but not only to systems for construction of pool fences or balustrades. The systems might also be suitable for other structures which in some cases have picket-like features in common with fences, such as ladders or walls. [0003] Pool fences are constructed in a wide variety of ways. A standard pool fence typically has a number of aluminum panels that are formed separately and then placed in position together. Each panel has two or more horizontal rails that sup...
