Pool Filter

Abstract

A pool filter for use in pool piping or other fluid conveyance system. The pool filter may include a housing defining a fluid chamber for receiving one or more filters. Multiple openings may be defined in the housing for receiving and removing fluid from the fluid chamber. The openings may be approximately the same size and may be located on the housing at similar elevations and/or radial sectors. One or more footings may be joined to the housing. Each footing may include a base portion for receiving anchor members to anchor the housing to a support surface. The footings may be designed to transfer to the support surface predetermined lateral or other forces imposed upon the pool filter by events such as earthquakes and hurricanes. The footings may be separate components joined to the housing by tabs and/or mechanical fasteners.

1 . A pool filter comprising:
 a housing defining a chamber for receiving a filter, a fluid inlet in fluid communication with the chamber, and a fluid outlet in fluid communication with the chamber;   a filter; and   at least one footing joined to the housing and adapted to receive an anchoring member to anchor the housing to a support surface.   
     
     
         2 . The pool filter of  claim 1 , wherein the at least one footing includes a pair of legs configured to form an angle. 
     
     
         3 . The pool filter of  claim 2 , wherein at least one of the pair of legs abuts the housing. 
     
     
         4 . The pool filter of  claim 2 , wherein at least one of the pair of legs abuts the support surface. 
     
     
         5 . The pool filter of  claim 2 , wherein at least one of the pair of legs defines a hole for receiving the anchoring member. 
     
     
         6 . The pool filter of  claim 1 , wherein the anchoring member comprises an anchor bolt. 
     
     
         7 . The pool filter of  claim 1 , wherein the housing includes at least one slot, and the at least one footing includes at least one tab sized for receipt within the slot. 
     
     
         8 . The pool filter of  claim 7 , wherein the at least one tab engages the housing to resist removal of the at least one footing from the housing. 
     
     
         9 . The pool filter of  claim 7 , wherein the at least one footing includes a member extending from the at least one footing and at least one of the at least one tab is positioned at a distal end of the member. 
     
     
         10 . The pool filter of  claim 1 , wherein the at least one footing comprises at least one leg and at least one gusset connected to the at least one leg. 
     
     
         11 . A pool filter comprising:
 a housing defining a chamber for receiving a filter, and including at least one first opening that functions as a fluid inlet in fluid communication with the chamber and at least one second opening that functions as a fluid outlet in fluid communication with the chamber;   a filter; and   at least one footing associated with the housing and configured to receive an anchoring member to anchor the housing to a support surface,   wherein the at least one footing comprises a main body portion, the main body portion comprising an upright leg and a base leg.   
     
     
         12 . The pool filter of  claim 11 , wherein the upright leg and the base leg are joined at first ends. 
     
     
         13 . The pool filter of  claim 11 , wherein at least one gusset is joined to the main body portion of the footing. 
     
     
         14 . The pool filter of  claim 11 , wherein the housing further comprises at least one third opening that functions as a drain, the third opening in fluid communication with the chamber. 
     
     
         15 . The pool filter of  claim 11 , wherein the fluid inlet and the fluid outlet are positioned approximately on a same side of the housing. 
     
     
         16 . The pool filter of  claim 11 , wherein the fluid inlet and the fluid outlet are approximately a same size. 
     
     
         17 . The pool filter of  claim 11 , wherein the fluid inlet and the fluid outlet are positioned approximately on an opposite side of the housing. 
     
     
         18 . The pool filter of  claim 11 , wherein the housing includes at least one slot, and the footing includes a pair of prongs, each prong having a tab at an end of the prong, the tab configured for receipt within the slot such that the prong engages the housing to resist removal of the at least one footing from the housing. 
     
     
         19 . The pool filter of  claim 11 , wherein the at least one fitting is joined to the housing by heat or sonic welding or an adhesive or a combination thereof. 
     
     
         20 . The pool filter of  claim 11 , wherein the housing further comprises an upper portion and a lower portion and the at least one footing is joined to the lower portion of the housing.
