Assembly and method of mounting a liquid delivery device utilizing expanding bushing

Abstract

A flanged bushing top portion is applied to a sink or counter surface over a mounting hole with a skirt portion descending from the top portion of the flanged bushing in to the mounting hole. A tapered expansion sleeve is threaded into the skirt portion of the flanged bushing. As the tapered expansion sleeve is threaded upwards into the tapered skirt portion, the skirt expands and pressed against the inside diameter of the sink mounting hole thereby securing the flanged bushing to the sink surface. A faucet valve assembly, soap/lotion dispenser, or water dispenser is lowered into the bores of the flanged bushing and the expansion sleeve, and the valve's escutcheon collar is secured to the top of the flanged bushing by means of a lock down collar which is threaded onto the exterior threads of the flange of the flanged bushing. This secures the valve assembly, soap/lotion dispenser, or water dispenser to the flanged bushing and consequently to the sink. This same method is utilized to attach the faucet spout securely to the sink.

         2 . The mounting assembly according to  claim 1  wherein said threaded outer surface of said expansion sleeve and said threaded bore have a truncated conical configuration for urging said expandable members outward.  
     
     
         3 . The mounting assembly according to  claim 2  wherein said expandable members are a plurality of flexible fingers.  
     
     
         4 . The mounting assembly according to  claim 2  further including a flange on said flanged bushing, said flange having a circular configuration and a flat lower surface for contacting the upper surface of the support member.  
     
     
         5 . The assembly according to  claim 4  further comprising a locking collar including an opening having interior threads, said flanged bushing having a threaded periphery for engaging said the interior threads of said locking collar, said locking collar being moveable relative to said flange through rotation of said locking collar relative to said flange for locking said flanged bushing on the upper surface of the support member.  
     
     
         6 . The mounting assembly according to  claim 5  further comprising an upper collar having a threaded bore in alignment with the bore of said flanged bushing for receiving the liquid delivery device, said upper collar being secured to said locking collar.  
     
     
         7 . The mounting assembly according to  claim 6  wherein said upper collar has a lower cylindrical portion for contacting the top of said flanged bushing, said cylindrical portion having a periphery having a conical shape, said locking collar having an upper conical shape in said threaded bore for engaging and locking said upper collar.  
     
     
         8 . The mounting assembly according to  claim 2  wherein said threaded exterior of said expansion sleeve includes a plurality of vertical key slots, said means for rotating said expansion sleeve comprises a rotatable tool.  
     
     
         9 . The mounting assembly according  claim 8  wherein said rotatable tool includes a shaft selectively extending through said bore of said flanged bushing and a blade for engaging a pair of said key slot for rotating said expansion sleeve through rotation of said shaft.  
     
     
         10 . The mounting assembly according to  claim 9  wherein the liquid delivery device is a water faucet.  
     
     
         11 . The mounting assembly according to  claim 9  wherein the liquid delivery device is a soap/lotion dispenser.  
     
     
         12 . The mounting assembly according to  claim 9  wherein said liquid delivery system is a water dispenser.  
     
     
         13 . The mounting assembly according to  claim 1  wherein said support member is either a sink top or a tub counter.  
     
     
         14 . A method of mounting a liquid delivery device having a downwardly descending hose on a bushing inserted downward through the mounting holes of a support surface having upper and lower surfaces comprising the steps of 
 inserting a flanged bushing having a lower expandable skirt and a threaded central bore having a truncated conical configuration through the mounting hole of the support member,    inserting an exteriorly threaded expansion sleeve into threaded engagement with said threaded central bore of said flanged bushing,    attaching a locking collar on said flanged bushing to lock said bushing to the top of the upper surface,    inserting a tool into said threaded bore of said bushing into engagement with said expansion sleeve, and    rotating said expansion sleeve relative to said threaded central bore to cause movement of said expansion sleeve and wedge said expandable skirt outward to a diameter greater that the diameter of the mounting hole for the sole mounting of said flanged bushing.    
     
     
         15 . The method according to  claim 14  wherein said threaded periphery of said expansion sleeve has a plurality of vertical slots, inserting said tool having a lower blade and an upper extending shaft into said threaded central bore to allow said blade to contact a plurality of vertical slots, rotating said shaft for causing rotation of a said expansion sleeve for relative wedging movement of said expandable skirt outward.  
     
     
         16 . The method according to  claim 15  further mounting an upper collar on said locking collar, mounting the liquid delivery device on said upper collar with said hose descending downward through the central bore of said flanged bushing and said expansion sleeve.
