Articulated Kneeboard for Concrete Finishers

Abstract

A kneeboard for concrete worker has a knee pan which contains a cushioned knee pad, and a toe pan. The pans are interconnected by links which permit them to pitch with respect to one another, so that the pans can remain flush even when they are on different non-coplanar surfaces. This enables a concrete finisher to move over steps and obstacles without damaging the surface of the concrete.

1 . An articulated kneeboard for concrete finishers, said kneeboard comprising
 a knee pan,   a toe pan, and   structure interconnecting said pans in a way that permits each of the toe pans to pivot with respect to the other about at least one axis, whereby the pans can rest flush on respective non-coplanar surfaces.   
   
   
       2 . The invention of  claim 1 , wherein the interconnecting structure is a pair of laterally spaced links, each extending between the knee pan and the top pan, and the links are connected to each pan by a movable joint. 
   
   
       3 . The invention of  claim 2 , wherein each movable joint is a pin joint. 
   
   
       4 . The invention of  claim 2 , wherein each movable joint is a universal joint. 
   
   
       5 . The invention of  claim 2 , wherein each of said links is length adjustable. 
   
   
       6 . The invention of  claim 1 , further comprising a resilient knee pad secured in said knee pan. 
   
   
       7 . The invention of  claim 1 , further comprising an accessory holder attached to said knee pan. 
   
   
       8 . The invention of  claim 1 , wherein each of said pans has a broad flat bottom. 
   
   
       9 . The invention of  claim 8 , where the knee pan has sloping surfaces extending front and rear from said flat bottom. 
   
   
       10 . The invention of  claim 1 , wherein each of the pans has slots for receiving respective retaining straps. 
   
   
       11 . The invention of  claim 1 , wherein said pivot axis is transverse to a longitudinal axis extending between said pans.
