Portable screen

Abstract

A portable safety screen is constructed of sight blocking material and supported by spaced apart uprights. A line extends between the uprights and the sight blocking material is connected to the line. The sight blocking material has a plurality of air passage cuts extending therethrough.

1 . A portable screen, comprising: 
 a plurality of spaced apart uprights;    a primary support line connected to and extending between the uprights; and    a sight blocking material connected to the primary support line and extending between the uprights, said blocking material having a plurality of air passage cuts extending therethrough.    
   
   
       2 . A portable screen, as set forth in  claim 1 , wherein there are a multiplicity of air passage cuts extending through the sight blocking material from the bottom of the sight blocking material to adjacent the primary support line.  
   
   
       3 . A portable screen, as set forth in  claim 2 , wherein the multiplicity of air passage cuts are transversely separated one from the other by at least 4 inches.  
   
   
       4 . A portable screen, as set forth in  claim 2 , wherein the multiplicity of air passage cuts are transversely separated one from the other in the range of about 4 to about 12 inches.  
   
   
       5 . A portable screen, as set forth in  claim 1 , wherein the lower portion of the uprights is of tri-pod construction.  
   
   
       6 . A portable screen, as set forth in  claim 5 , wherein the tri-pod lower portion of each upright is removeably connected to the upright and the end portion of the upright is tapered to a point.  
   
   
       7 . A portable screen, as set forth in  claim 1 , wherein the line extending between and connecting the uprights is a nylon line.  
   
   
       8 . A portable screen, as set forth in  claim 1 , wherein the line extends beyond the last upright on each end and is connectable to a stationary object for stabilizing the portable screen.  
   
   
       9 . A portable screen, as set forth in  claim 1 , including first and second lines each extending from the upper end portion of each upright to the ground at a distance of about 6 feet from the respective upright, each first and second line being connectable to a stationary object for stabilizing the portable screen.  
   
   
       10 . A portable screen, as set forth in  claim 1 , wherein the sight blocking material is formed of organic plastic.  
   
   
       11 . A portable screen, as set forth in  claim 10 , wherein the sight blocking material is formed of polyethylene.  
   
   
       12 . A portable screen, as set forth in  claim 10 , wherein the uprights are formed of organic plastic.  
   
   
       13 . A portable screen, as set forth in  claim 1 , wherein the portable screen is sufficiently flexible per 50 feet of length to be rolled into a cylindrical form having a diameter less than 12 inches.  
   
   
       14 . A portable screen, as set forth in  claim 1 , wherein the portable screen is at least 6 feet in height and at least 50 feet in length.  
   
   
       15 . A portable screen, as set forth in  claim 1 , wherein the sight blocking material includes first and second layers each having air passage cuts, said air passage cuts of the first layer being laterally offset relative to the air passage cuts of the second layer.  
   
   
       16 . A portable screen, as set forth in  claim 1 , including a stabilizing bar connectable to an upper end portion of an upright and being maintainable relative to the ground.  
   
   
       17 . A portable screen, as set forth in  claim 16 , wherein the stabilizing bar is formed of organic plastic.
