Micro Bellows


Micro Bellows

for folding cameras


      In 1978 Kodak had a line of cameras that required an even number of mirrors (0, 2, etc.),  Steve Hines, in the Kodak Research Laboratories, proposed a folding camera with a 2-mirror support, covered with a heavily textured black rubber membrane to lay flat against the back when closed, and to expand around the open mirror support when open. 


      Above is a highly enlarged drawing of the rubber covering with a peak-to-peak spacing of 2-3mm.  The surface had undulations in every direction so that it could expand equally in all directions.  


      This is the subject of U.S. Patent 4,279,492 assigned to Eastman Kodak.  This is not a product being offered for sale by HinesLab but is an example of engineering that companies might expect on a contract consulting basis.  Please contact Steve Hines at:
