Patent ID: RE39842

Claim:
An improved temporary guardrail system for removable attachment to a building under construction including a plurality of upright stanchions, each respective stanchion having an anchor bracket on a bottom end thereof, said stanchions being connected by a plurality of vertically spaced upper and lower side rails and by toe board, the improvements comprising: means for rotatably connecting said rails to said stanchions enabling each respective side rail to be rotated 360° about a longitudinal axis of each respective stanchion in a horizontal plane and each respective side rail to be pivoted at varying angles in a vertical plane, said connecting means including a first threaded stud outwardly projecting from a top end of said stanchions in substantially axial alignment therewith enabling each of said upper side rails to be rotatably mounted thereon at various angles, said upper side rails being pivoted in a vertical plane at varying angles by use of angulation means, said angulation means comprising a generally L-shaped swivel bracket disposed on said first threaded stud at said top end of said stanchion, said L-shaped bracket including a long leg portion and a short leg portion being fixedly attached in perpendicular relation thereto, said bracket further including swiveling means being adapted for pivoting movement in a plane parallel to the plane defining said long leg portion, said swiveling means including a second threaded stud disposed in perpendicular relation to said axis of said stanchion enabling said upper side rails to be mounted thereon and pivoted in a vertical plane at varying angles for installation of said temporary guardrail system on inclines such as stairs; means for telescopically adjusting the length of each respective side rail and said toe board enabling said temporary guardrail system to be adapted to dimensional features of different buildings under construction; and means for selectively extending the vertical height of said guardrail system to provide an increased measure of safety for employees performing specialized tasks requiring ladders and stilts adjacent thereto.
