Hole closing plug

Abstract

A closure for an opening through a partition includes a barrier surrounded by a perimetral wall having an outside surface dimensioned to fit in the opening and a continuous outwardly extending flange. A plurality of tension members are hinged to the perimetral wall by a thin frangible web and include second ends having openings arranged in overlapping relation to each other. A tether passes through the overlapped openings of the second ends and includes a handle-forming loop.

What is claimed is:  
     
         1 . A molded plug for forming a closure for an opening through a partition, the plug comprising: 
 a barrier surrounded by a perimetral wall having an outside surface dimensioned to fit in the opening and bounded by a leading edge and a trailing edge,    a flange protruding outward from the perimetral wall, and    a plurality of tension members having first ends coupled to the leading edge and second ends including a coupling for coupling to a teather.    
     
     
         2 . The molded plug of  claim 1  wherein the barrier and the flange lie in a common plane.  
     
     
         3 . The molded plug of either  claim 1  or  2  wherein the flange is connected to the trailing edge of the perimetral wall.  
     
     
         4 . The molded plug of  claim 3  wherein the perimetral wall is continuous.  
     
     
         5 . The molded plug of  claim 4  wherein the flange is circumferentially continuous.  
     
     
         6 . The molded plug of  claim 1  wherein the first ends of the tension members includes a thin web hinging the tension members to the perimetral wall.  
     
     
         7 . The molded plug of  claim 6  wherein the thin web of the first ends of the tension members is frangible under a tension load supportable by said flange.  
     
     
         8 . The molded plug of  claim 1  wherein the coupling on the tension members second ends comprises an opening.  
     
     
         9 . A closure for an opening through a partition, the closure comprising: 
 a barrier surrounded by a perimetral wall having an outside surface dimensioned to fit in the opening and bounded by a leading edge and a trailing edge,    a flange protruding outward from the perimetral wall,    a plurality of tension members having first ends coupled to the leading edge and second ends arranged in overlapping relation to each other, and    a tether coupled to the overlapped second ends.    
     
     
         10 . The closure of  claim 9  wherein the barrier and the flange lie in a common plane.  
     
     
         11 . The closure of either  claim 9  or  10  wherein the flange is connected to the trailing edge of the perimetral wall.  
     
     
         12 . The closure of  claim 11  wherein the perimetral wall is continuous.  
     
     
         13 . The closure of  claim 11  wherein the flange is circumferentially continuous.  
     
     
         14 . The closure of  claim 9  wherein the first ends of the tension members includes a thin web hinging the tension members to the perimetral wall.  
     
     
         15 . The closure of  claim 14  wherein the thin web of the first ends of the tension members is frangible under a tension load supportable by said flange.  
     
     
         16 . The closure of  claim 9  wherein the coupling on the tension members second ends comprises an opening.  
     
     
         17 . The closure of  claim 16  wherein the tether comprises a cord passing through the opening of the tension members second ends.  
     
     
         18 . The closure of  claim 17  wherein the tether further comprises an enlarged first end sized to be retained by the opening of the tension members second ends.  
     
     
         19 . The closure of  claim 18  wherein the tether further comprises a second end including a handle-forming loop.  
     
     
         20 . A closure for an opening through a partition, the closure comprising: 
 a barrier surrounded by a continuous perimetral wall having an outside surface dimensioned to fit in the opening and bounded by a leading edge and a trailing edge,    a continuous flange protruding outward from the trailing edge,    a plurality of tension members having first ends including a thin frangible web hinging the tension members to the leading edge and second ends including openings arranged in overlapping relation to each other, and    a tether passing through the overlapped openings of the second ends, the tether having an enlarged first end sized to be retained by the openings and a second end including a handle-forming loop.
