Shower drain and protective cover

Abstract

Shower drain assemblies and their components are disclosed. In examples, a shower drain assembly may include a receptor, a threaded flange, a plate, and a protective cover. The protective cover may protect the plate, the threaded flange, or other components from damage. The protective cover may be installed directly onto the threaded flange or onto the plate when the plate is installed onto the threaded flange. The same protective cover can thus be used to protect shower drain assemblies at different stages of installation—whether or not trim pieces such as the plate have yet been installed.

1 - 7 . (canceled) 
     
     
         8 . A protective cover for a shower drain assembly, the protective cover comprising:
 a top surface;   a bottom surface;   a first pair of friction tabs extending from the bottom surface, wherein each of the first pair of friction tabs includes a first hook portion facing radially inward; and   a second pair of friction tabs extending from the bottom surface, wherein each of the second pair of friction tabs includes a second hook portion facing radially outward.   
     
     
         9 . The protective cover of  claim 8 , further comprising a lip around the perimeter of the protective cover. 
     
     
         10 . The protective cover of  claim 8 , wherein a perimeter of the protective cover is round, and an outer diameter formed by the first pair of friction tabs is less than the outer diameter formed by the second pair of friction tabs. 
     
     
         11 . The protective cover of  claim 8 , wherein the protective cover comprises molded, flexible elastomer and the first pair of friction tabs and the second pair of friction tabs are integrally formed with the bottom surface. 
     
     
         12 . The protective cover of  claim 8 , further comprising:
 a third pair of friction tabs extending from the bottom surface, wherein each of the third pair of friction tabs includes a third hook portion facing radially inward; and   a fourth pair of friction tabs extending from the bottom surface, wherein each of the fourth pair of friction tabs includes a fourth hook portion facing radially outward.   
     
     
         13 - 20 . (canceled) 
     
     
         21 . The protective cover of  claim 8 , wherein the first hook portion is configured to engage a drainage hole of a plate installed on a threaded flange. 
     
     
         22 . The protective cover of  claim 8 , wherein the second hook portion is configured to engage a groove formed in an upper interior surface of a threaded flange. 
     
     
         23 . The protective cover of  claim 8 , wherein the first pair of friction tabs and the second pair of friction tabs are spaced symmetrically about the bottom surface. 
     
     
         24 . The protective cover of  claim 8 , wherein the first pair of friction tabs is shorter in length than the second pair of friction tabs. 
     
     
         25 . The protective cover of  claim 8 , wherein the second pair of friction tabs is configured to extend through drainage holes of a plate and engage with a groove in the threaded flange. 
     
     
         26 . The protective cover of  claim 8 , wherein a lip of the protective cover is configured to frictionally engage an outer perimeter of a plate or a threaded flange. 
     
     
         27 . The protective cover of  claim 8 , wherein the protective cover is configured to cover one or more drainage holes of a plate to reduce debris from falling into the drain assembly. 
     
     
         28 . The protective cover of  claim 8 , wherein the protective cover is configured to be installed directly onto a threaded flange when no plate is installed. 
     
     
         29 . The protective cover of  claim 8 , wherein the protective cover is configured to obscure at least a portion of a plate installed on the threaded flange. 
     
     
         30 . The protective cover of  claim 8 , wherein the second pair of friction tabs is configured to exert an outward force against an upper interior surface of the threaded flange. 
     
     
         31 . The protective cover of  claim 8 , wherein the first and second pairs of friction tabs are positioned to avoid obstructing drainage holes of a plate. 
     
     
         32 . The protective cover of  claim 8 , wherein the first and second hook portions are configured to engage with a bottom surface of a plate or a threaded flange. 
     
     
         33 . The protective cover of  claim 8 , wherein the friction tabs are configured to extend through drainage holes on either side of a friction tab of a plate. 
     
     
         34 . The protective cover of  claim 8 , wherein the first and second pairs of friction tabs are configured to engage through drainage holes on opposite sides of different friction tabs of a plate. 
     
     
         35 . The protective cover of  claim 8 , wherein the friction tabs are spaced radially about the bottom surface of the protective cover.
