Benefits of technology

[0026]In accordance with one aspect of the present invention, there is provided a base element for assembly of a roofing bracket, wherein the roofing bracket has an upper member. The base element comprises a fastening means for removably atta...

Problems solved by technology

These means are typically not used for metal roofs, due to the resulting permanent puncture damage to the roof.
However, in practice many roofing brackets do not permit any angular adjustment, suggesting the need for a simple and sturdy roofing bracket that can easily be used at different angles and does not rely on the engagement of a prop.
The prior art in this field suffers from a number of drawbacks.
In U.S. Pat. No. 6,164,033, the seam is disfigured permanently by bolts that attach the clamp to the seam directly, which increases the likelihood of roof leakage.
In bo...

Embodiment Construction

[0074]FIGS. 1 to 3 illustrate one embodiment of the base (10), which may be a metal pressing or a casting, preferably made of steel. It and has a flat underside portion including an attachment strip (10a) at a normally upper end, and which divides into spaced surface portions (10b) separated by a flat raised portion (10c) extending down to the normally lower end. The attachment strip (10a) has angled slots (12) for receiving nails or other suitable attachment means allowing the strip to be temporarily and removably secured to a roof.

[0075]The flat raised portion 10c is parallel to the underside and connected thereto by sloping shoulders (10d). The raised portion (10c) has a pair of keyhole-shaped slots (14) adjacent its ends, with the larger ends of the keyhole slots being at the normally upper end. The raised portion (10c) is preferably cast, rather than welded, for enhanced structural strength.

[0076]FIGS. 4-6 show another embodiment of the base member (100), in which the shoulders...

Abstract

A base element for assembly of a roofing bracket comprises a fastening means for temporarily or attaching the base element to a metal or non-metal roof and an upper surface. The upper surface comprises a means for engagement of an underside of an upper member of the roofing bracket. The upper member can be selectively attached to the base element in a first or second position.

Description

RELATED APPLICATIONS[0001]This application claims priority from U.S. Provisional patent application Ser. No. 60 / 893,250 entitled “Roofing Bracket for Supporting a Platform” filed Mar. 6, 2007. This application is incorporated by reference herein in its entirety.BACKGROUND OF THE INVENTION[0002]The present invention relates to a base element used in the assembly of roofing brackets, and to roofing brackets used for the support of roofing accessories and equipment.[0003]Roofing brackets have been used for many years for supporting roofing accessories and equipment. Usually, a roofing bracket is designed for the attachment of a specific type of accessory. For example, a certain class of roofing brackets has been designed for the support of one or more planks to provide a generally horizontal platform for use by roofers. Another class of roofing brackets can be used only for the attachment of safety lanyards. Yet a third class includes roofing brackets designed solely for the attachment...
