Benefits of technology

[0020] In accordance with this invention, there is disclosed a movable and repositionable safety rail for use with scaffolding which includes a pair of spaced apart vertical posts in connected relationship with at least two horizontal cross-members defining a frame, a pair of downwardly extending legs from a bottom of said frame, at least one load-bearing and positioning means on each leg for contacting engagement with said scaffolding, and at least one stabilization means on each leg, said stabilization means in only non-permanent, physical contacting relationship with said scaffolding. In a prefer...

Problems solved by technology

However, it has been found that workers can, for one reason or another, fall through unprotected spaces between the floor, cross braces, and uprights.
While it is fairly easy to hang guard rails on erected portions of scaffolding, it is practically impossible to provide guard rails on the next uppermost level to be erected with the structures and equipment currently available in the industry.
There is, however, an inherent problem in building scaffolding in how to provide fall prevention means at the top of scaffolding before the workmen get up on that level to complete the assembly thereof.
But this raises the problem of what to attach the safety harness to.
However, if there is no structure adjacent to the scaffolding, then this is not a viable solution.
This leaves on...

Embodiment Construction

[0039] Referring now to the drawings wherein the showings are for purposes of illustrating the preferred embodiment of the invention only and not for purposes of limiting the same, the figures show a movable and repositionable safety rail 40 for use with a tubular frame scaffolding system 10 which comprises a plurality of trusses, a plurality of cross-braces, a plurality of work platforms, and optionally a plurality of safety accessories. As used in this application, references to “vertical” will mean a “Z” direction which is essentially normal to a level ground plane, whereas references to “horizontal” will mean an “X-Y” direction which is essentially normal to a plane defined by a wall of a building to which a scaffolding system is affixed. References to “right” and “left” will use a reference point when viewing the scaffolding positioned about a facility looking toward that facility. It will be understood that when viewing the scaffolding using a rear elevational view shown in FI...

Abstract

The invention relates generally to movable and repositionable safety guard rails for use with scaffolding.

Description

TECHNICAL FIELD [0001] The invention relates generally to the art of scaffolding, and in particular, to movable and repositionable safety guard rails for scaffolding. BACKGROUND OF THE INVENTION [0002] In typical scaffold constructions, two spaced apart upright members are secured in proper upright position on base members and held in place by side cross braces. Safety guard rails are attached between the uprights on the outward side of the scaffolding, the side away from a building. Floor boards are extended between the uprights so that workmen can stand on and work on the stable, elevated temporary flooring. However, it has been found that workers can, for one reason or another, fall through unprotected spaces between the floor, cross braces, and uprights. For this reason the Occupational Safety and Health Administration or “OSHA,” a federal regulatory and safety agency has imposed many regulations on the industry to require suitable fall protection on the scaffolding. While it is...
