Trolley for transporting materials on seamed roofs

Abstract

Trolley for transporting materials that traverses seams and stepped sections of a roof includes a bed mounted on aligned frames that house wheels. Once positioned on the roof seams, roofing materials are hoisted onto the trolley for positioning where the materials are needed. The trolley may include a brake.

1 . A trolley for transporting materials on a roof having standing seams comprising: 
 a bed; and    a wheel fixed relative to said bed configured to roll on the roof guided by a seam therein.    
   
   
       2 . The trolley of  claim 1 , wherein said bed has a box-shaped cross-section.  
   
   
       3 . The trolley of  claim 1 , further comprising a rib mounted on said bed.  
   
   
       4 . The trolley of  claim 1 , further comprising a deck fixed relative to said wheel; 
 wherein: 
 the roof comprises: 
 a first section; and  
 a second section; and  
 
 when said trolley is disposed on the second section, said deck is alignable with the first section.  
   
   
   
       5 . The trolley of  claim 4 , further comprising a simulated roof seam mounted on said deck.  
   
   
       6 . The trolley of  claim 5 , wherein: 
 the first section includes a first seam therein; and    when said trolley is disposed on the second section, said simulated roof seam is alignable with the first seam.    
   
   
       7 . The trolley of  claim 1 , further comprising a frame interposed between said bed and said wheel.  
   
   
       8 . The trolley of  claim 1 , wherein said wheel has an annular recess for receiving the seam.  
   
   
       9 . The trolley of  claim 1 , further comprising a second wheel fixed relative to said bed configured to roll on the roof guided by the seam.  
   
   
       10 . The trolley of  claim 9 , wherein said wheel and said second wheel are oriented to be guided by a single seam.  
   
   
       11 . The trolley of  claim 9 , wherein said wheel and said second wheel are oriented to be guided by aligned seams.  
   
   
       12 . A trolley for transporting materials on a roof comprising: 
 a bed;    a wheel fixed relative to said bed configured to roll on the roof; and    a brake fixed relative to said bed configured to frictionally engage the roof.    
   
   
       13 . The trolley of  claim 12 , further comprising a deck fixed relative to said wheel; 
 wherein: 
 the roof comprises: 
 a first section; and  
 a second section; and  
 
 when said trolley is disposed on the second section, said deck is alignable with the first section.  
   
   
   
       14 . The trolley of  claim 13 , further comprising a simulated roof seam mounted on said deck.  
   
   
       15 . The trolley of  claim 14 , wherein: 
 the first section includes a first seam therein; and    when said trolley is disposed on the second section, said simulated roof seam is alignable with the first seam.    
   
   
       16 . The trolley of  claim 12 , further comprising a frame interposed among said bed, said wheel and said brake.  
   
   
       17 . The trolley of  claim 12 , wherein said wheel is configured to be guided by a seam in the roof.  
   
   
       18 . The trolley of  claim 12 , wherein said wheel has an annular recess for receiving a seam in the roof.  
   
   
       19 . The trolley of  claim 12 , wherein said brake is biased toward contacting the roof.  
   
   
       20 . The trolley of  claim 12 , wherein said brake is configured to contact the roof proximate to more than one seam in the roof.  
   
   
       21 . The trolley of  claim 12 , further comprising a handle for releasing said brake.  
   
   
       22 . The trolley of  claim 21 , wherein said handle may be articulated into a position for moving said trolley relative to the roof.  
   
   
       23 . The trolley of  claim 21 , wherein said brake comprises: 
 a rod operably connected to said handle;    a pin operably connected to said rod; and    a brake pad fixed relative to said pin;    whereby articulating said handle rotates said rod and moves said pin and said brake pad relative to the roof.    
   
   
       24 . The trolley of  claim 23 , said brake further comprising a knuckle fixed relative to said rod; 
 whereby said handle may be articulated to drive said knuckle against said trolley to move said trolley relative to the roof.    
   
   
       25 . The trolley of  claim 21 , further comprising a second handle fixed relative to said handle.  
   
   
       26 . The trolley of  claim 21 , further comprising a second handle fixed relative to said trolley.
