Expandable Backflow Cage

Abstract

Disclosed is a cage assembly having a first cage portion and a second cage portion where the first and second cage portions together form a cage enclosure with an adjustable length.

1 . A cage assembly comprising:
 a first cage portion comprising a surface, an open front and a closed back and a second cage portion comprising a surface, an open front and a closed back,   wherein the first and second cage portions together form a cage enclosure with an adjustable length.   
     
     
         2 . The cage assembly of  claim 1  wherein the cage enclosure is attached to a foundation. 
     
     
         3 . The cage assembly of  claim 1  wherein the foundation is formed using an adjustable foundation form. 
     
     
         4 . The cage assembly of  claim 1 , wherein the first cage portion is smaller than the second cage portion and at least a portion of the first cage portion can fit inside the second cage portion. 
     
     
         5 . The cage assembly of  claim 4 , wherein the length of the cage assembly can be determined by varying the amount of the first cage portion housed by the second cage portion. 
     
     
         6 . The cage assembly of  claim 1 , wherein the second cage portion comprises a lock mechanism and the first cage portion comprises a hasp. 
     
     
         7 . The cage assembly of  claim 6 , wherein first cage portion comprises a bar that runs along at least a portion of the length of the first cage portion and wherein the hasp is attached to any location along the bar. 
     
     
         8 . The cage assembly of  claim 7 , wherein the location of the hasp can be altered to any point along the bar. 
     
     
         9 . The cage assembly of  claim 7 , wherein the hasp can be positioned at any number of predetermined points on the bar. 
     
     
         10 . The cage assembly of  claim 6 , wherein the lock mechanism mates with the hasp to form a locked cage enclosure. 
     
     
         11 . The cage assembly of  claim 1 , wherein the first cage portion is at least partially supported by at least one hinge assembly. 
     
     
         12 . The cage assembly of  claim 1 , wherein the second cage portion is at least partially supported by at least one hinge assembly. 
     
     
         13 . The cage assembly of  claim 1 , wherein the rear of the second cage portion is attached to a foundation by a hinge assembly. 
     
     
         14 . The cage assembly of  claim 1 , wherein the rear of the first cage portion is attached to a foundation by a hinge assembly and the rear of the second cage portion is attached to a foundation by a hinge assembly. 
     
     
         15 . The cage assembly of  claim 7 , wherein the location of the hasp along the bar determines the length of the cage assembly. 
     
     
         16 . The cage assembly of  claim 1 , wherein the surfaces of the first cage portion and the second cage portion comprise expanded metal. 
     
     
         17 . The cage assembly of  claim 7 , wherein the bar is positioned outside of the surface of the first cage portion. 
     
     
         18 . A method of securing piping assembly comprising:
 enclosing a piping assembly with a cage enclosure having a first cage portion and a second cage portion, wherein the first and second cage portions together form a cage enclosure that can have an adjustable length.   
     
     
         19 . The method of  claim 18 , further comprising attaching the cage enclosure to a foundation. 
     
     
         20 . The method of  claim 18 , further comprising forming a foundation using an adjustable foundation form.
