Abstract
Abstract One or more elongated roller assemblies may be selectively mounted at a variety of positions along the inner edge of a scaffold platform. The inner and outer edges of the platform each include a series of correspondingly spaced apertures therethrough which receive the support rods or shafts of the roller assemblies. When the roller assemblies are emplaced the rollers lie between the inner edge of the platform and the vertical wall of the building along which the scaffolding is moving, and the mounting or support rods extend entirely through the platform and act as reinforcement of the assembly.

Claim 1
Independent Claim
214 words
A suspended scaffold for use in transporting equipment and/or personnel along the vertical wall of a building or structure, said suspended scaffold comprising: (a) a load bearing platform including a forward edge, an opposite rear edge, and a plurality of passageways extending through said platform between said front and rear edges; (b) suspension means operably connected to said platform for moving said platform along the vertical building wall while maintaining said platform horizontal with said front edge facing said building wall; (c) a plurality of roller assemblies; each including: (i) a mounting bracket carrying at least one force absorbing elongated roller formed of a resilient material; (ii) at least two support rods secured to said mounting bracket and extending rearwardly therefrom, said support rods, when assembled, extending entirely through selected ones of said passageways from said front through said rear edge for detachably mounting said roller assembly at one of various selected points along said forward side of said platform; (d) means for retaining said support rods in assembled relation through said platform; whereby said roller assemblies may be positioned on said platform at spaced points corresponding to the spaces between solid building portions extending between the windows thereof so that said rollers move along the building wall preventing damage thereto by said scaffold.

A suspended scaffold for use in transporting equipment and/or personnel along the vertical wall of a building or structure, said suspended scaffold comprising: (a) a load bearing platform including a forward edge, an opposite rear edge, and a plurality of passageways extending through said platform between said front and rear edges; (b) suspension means operably connected to said platform for moving said platform along the vertical building wall while maintaining said platform horizontal with said front edge facing said building wall; (c) a plurality of roller assemblies; each including: (i) a mounting bracket carrying at least one force absorbing elongated roller formed of a resilient material; (ii) at least two support rods secured to said mounting bracket and extending rearwardly therefrom, said support rods, when assembled, extending entirely through selected ones of said passageways from said front through said rear edge for detachably mounting said roller assembly at one of various selected points along said forward side of said platform; (d) means for retaining said support rods in assembled relation through said platform; whereby said roller assemblies may be positioned on said platform at spaced points corresponding to the spaces between solid building portions extending between the windows thereof so that said rollers move along the building wall preventing damage thereto by said scaffold.
Claim 3
Dependent Claim
153 words
An improvement in suspended scaffolding rigs of the type having a horizontal platform with a front and rear edge and used in transporting equipment and personnel along the vertical wall of a building or other structure, said improvement including a detachable bumper attachment comprising: (a) a plurality of elongated roller assemblies; (b) each roller assembly comprising a roller support bracket with at least two elongated support rods extending rearwardly therefrom; (c) a plurality of passageways extending horizontally through said platform from front to rear at spaced positions therein, the number of said passageways exceeding the number of support rods; (d) means for releasably securing said support rods within said passageways with the rods extending entirely across the front to rear dimension of said platform; (e) whereby said roller assemblies may be removed from a first set of passageways and inserted in another set of passageways to vary the spacing between said roller assemblies.
