Sheet material tensioning apparatus

      
Application Number 12772379
Grant Number 08307880
Status In Force
Filing Date 2010-05-03
First Publication Date 2010-08-19
Grant Date 2012-11-13
Owner Lucius Hudson, Inc. (USA)

Abstract

A sheet material tensioning apparatus includes frame members interconnected one with another to define a closed contour. The apparatus applies tension to sheet material by imposing a separation between frame members to expand the closed contour. Beneficially, the sheet material tensioning apparatus includes an edge-bridging mechanism, such as a spline, to span the gap between the separated frame members. The edge-bridging mechanism maintains the continuity of the edge supporting the sheet material. The sheet material apparatus may include a crossbar assembly to add rigidity to long frame members, while maintaining planar alignment even under considerable compression.
