Modular roof installation scaffolding system

Abstract

A modular roof installation scaffolding system comprises a plurality of light-weight, generally rectilinear rails having a plurality of regularly-spaced apertures extending laterally therethrough. The rails are supportable upon a plurality of feet adapted for pinned connection to the rails utilizing the apertures. One or more jacks are slidably supportable on the rails and are adapted for pinned connection to the rails. The jacks are adapted to support one or more planks extending orthogonally to and across the rails for supporting one or more roofing installers thereon. A roof hook is attachable to each rail for supporting the scaffolding on the roof at the ridgeline of the roof.

       9 . A modular roof installation scaffolding system according to  claim 8  and further comprising a plurality of apertures extending through the movable plank and fasteners extending through the apertures to couple the movable plank to the at least one jack.  
   
   
       10 . A modular roof installation scaffolding system according to  claim 6  and further comprising at least one line support pin attached to the rail for supporting at least one line.  
   
   
       11 . A modular roof installation scaffolding system according to  claim 10  wherein the at least one line support pin is attached to the rail by inserting the at least one line support pin through the apertures.  
   
   
       12 . A modular roof installation scaffolding system according to  claim 10  wherein the at least one line comprises at least one of a pneumatic supply line, an electric power cord, a vacuum line, and a water supply line.  
   
   
       13 . A modular roof installation scaffolding system according to  claim 1  and further comprising a cushion coupled to each foot for cushioning the contact of the foot with the roofing materials.  
   
   
       14 . A modular roof installation scaffolding system according to  claim 1  and further comprising at least one hook coupled to each rail and extending over the ridge to attach the scaffolding system to the roof.  
   
   
       15 . A modular roof installation scaffolding system according to  claim 1  and further comprising a plurality of apertures extending through the at least one jack and the movable plank, and fasteners extending through the apertures to couple the movable plank to the at least one jack.  
   
   
       16 . A modular roof installation scaffolding system according to  claim 1  wherein the rail comprises a pair of rails extending parallel to and in lateral registry with one another.  
   
   
       17 . A modular roof installation scaffolding system for attachment to a roof having an inclined roof deck and a ridge, comprising: 
 a rigid framework comprising at least two rails with a supporting plank extending between them, the rigid framework being supported away from the roof deck by at least two movable feet coupled to each rail;    wherein the at least two movable feet can be relocated along each rail between a first area of the roof deck having no installed roofing materials and a second area of the roof deck having installed roofing materials without disassembling the rigid framework;    whereby roofing materials can be installed on the roof deck beneath the scaffolding system without moving the rigid framework.    
   
   
       18 . A modular roof installation scaffolding system according to  claim 17  wherein the movable plank can be selectively repositioned along the rail without moving the at least two movable feet.  
   
   
       19 . A modular roof installation scaffolding system according to  claim 17  wherein the at least two rails and the supporting plank are provided with a plurality of apertures extending laterally therealong.  
   
   
       20 . A modular roof installation scaffolding system according to  claim 19  wherein the at least two rails and the supporting plank are rigidly coupled together by fasteners extending through the apertures.
