A telescopic scaffold comprising opposed pairs of elongated support legs each received in adjustable sleeve members securable at a predetermined location therealong. Arresting means is provided to interlock each sleeve member with its associated leg at a predetermined location therealong. An adjustable bracing end support structure is adjustably securable between each adjustable sleeve member of each pair of legs to secure each leg of the pairs of legs at a desired inclined angle to each other and at a desired spacing therebetween. A tubular support member is secured to each of the adjustable sleeve members and extends transverse to the longitudinal axis of the sleeve member and the end bracing. An intermediate horizontal support member is telescopically securable between opposed tubular members of the opposed pairs of support legs to constitute adjustable elongated side supports.
A telescopic scaffold comprising opposed pairs of elongated support legs, each said legs being received in an adjustable sleeve member securable at a predetermined location therealong, arresting means to interlock said sleeve member with its associated leg at said predetermined location, an adjustable bracing end support structure adjustably securable between each said adjustable sleeve members of each pair of said legs to secure each leg of said pairs of legs vertically or at a desired inclined angle to each other and at a desired spacing therebetween, a tubular support member secured to each said adjustable sleeve members and extending transverse to the longitudinal axis of said adjustable sleeve member and said end bracing, an intermediate horizontal support member telescopically securable between opposed tubular members of said opposed support legs to constitute adjustable elongated side supports, a vertical flange secured along each sleeve of said pairs of sleeves, a plurality of spaced apart holes in each flange, said adjustable bracing end support structure comprising a top and bottom transverse adjustable support member secured in a spaced apart relationship across opposed legs of each pair of legs and secured at their respective ends to said flanges of said pair of sleeves, adjustably securable brace members secured adjacent an end thereof to a selected one of said holes in an associated one of said vertical flanges of one of said pairs of sleeves and extending angularly toward said top transverse support members and having its other end secured thereto to provide a rigid top transverse support, said adjustable transverse supports having their lengths adjustably secured whereby to vary said inclined angle of each said sleeves and said legs.
A telescopic scaffold as claimed in claim 3 wherein said elongated bars are flat bars of right angle cross section, said holes in said bars being spaced apart holes in a vertical wall portion of said flat bars.
A telescopic scaffold as claimed in claim 4 wherein said securable means is constituted by one or more lock bolt fasteners extending through aligned ones of said holes in overlapped end portions of said two flat bars.
A telescopic scaffold as claimed in claim 5 wherein a fastener also secures said one end of a respective brace member to said support member, said flat bars having a horizontal wall portion disposed uppermost to constitute a flat support surface for supporting boards disposed thereon to form a support platform.
