Replacement non-scratch pads with detachable cover for rolling walker

Abstract

The present invention provides a replaceable cap designed to fit into the rear leg of walker. The cap has a non-scratch pad on the bottom surface which provides skidding action and removes the chirping noise caused by normal walkers. The cap is also designed to be inserted into a protective cover for use on rough surfaces.

1 . A replaceable cap adapted for installation on a terminal end of a leg on a walker to replace the elastomeric tip found at the end of said leg, said cap comprising:
 a non-scratch pad;   a recessed bottom bonded to the non-scratch pad, wherein one side of the recessed bottom is shaped to partially encase the non-scratch pad and another side of the recessed bottom is shaped to surround and frictionally engage the leg on a walker when the leg is inserted into said cap; and   a detachable cover for protecting the non-scratch pad on rough or outdoor surfaces, configured with concentric grooves, allowing the recessed bottom to snap into the cover.   
     
     
         2 . The cap of  claim 1 , wherein said recessed bottom is a cast or extruded shape. 
     
     
         3 . The cap of  claim 1 , wherein said recessed bottom is composed of fiberglass, thermoplastic, silicone or polyethylene.

         5 . The cap of  claim 1 , wherein said non-scratch pad is made from the group consisting of polyacrylate, polyamide, polyester, polyimide, polystyrene, polycarbonate, polypropylene and polyurethane. 
     
     
         6 . The cap of  claim 1 , wherein said detachable cover is cylindrically shaped with an outer wall partially cut open and designed to receive the outer edge of the recessed bottom. 
     
     
         7 . The cap of  claim 1 , wherein the detachable cover is made from fiberglass, thermoplastic, silicone, polyethylene or polyoxymethylene. 
     
     
         8 . The cap of  claim 1 , wherein the total weight of the cap is between about 50 grams to about 1000 grams. 
     
     
         9 . The cap of  claim 1 , wherein the diameter of the cover is between about 1 cm to about 5 cm. 
     
     
         10 . The cap of  claim 1 , wherein the total length of the cap is between about 4 cm to 10 cm. 
     
     
         11 . A replaceable cap adapted for installation on a terminal end of a leg on a walker, said cap comprising:
 a scratch resistant pad; and   a recessed bottom bonded to the scratch resistant pad, wherein one side of the recessed bottom is shaped to partially encase the scratch resistant pad and another side of the recessed bottom is shaped to surround and frictionally engage the leg on a walker when the leg is inserted into said cap.   
     
     
         12 . The cap of  claim 11 , wherein said recessed bottom is a cast or extruded shape. 
     
     
         13 . The cap of  claim 11 , wherein said recessed bottom is composed of fiberglass, thermoplastic, silicone or polyethylene. 
     
     
         14 . The cap of  claim 13 , wherein said thermoplastic is acrylonitrile, butadiene or styrene. 
     
     
         15 . The cap of  claim 11 , wherein said scratch resistant pad is made from the group consisting of polyacrylate, polyamide, polyester, polyimide, polystyrene, polycarbonate, polypropylene and polyurethane. 
     
     
         16 . The cap of  claim 11 , wherein the total weight of the cap is between about 25 grams to about 1000 grams. 
     
     
         17 . The cap of  claim 11 , wherein the total length of the cap is between about 2 cm to 8 cm. 
     
     
         18 . A detachable cover for protecting replaceable caps adapted for installation on the bottom legs of walkers, comprising:
 a hollow, cylindrical plastic cast or extruded figure, partially cut open and configured with concentric grooves.   
     
     
         19 . The detachable cover of  claim 18 , wherein the detachable cover is made from fiberglass, thermoplastic, silicone, polyethylene or polyoxymethylene. 
     
     
         20 . The detachable cover of  claim 18 , wherein the total weight of the detachable cover is between about 25 grams to about 750 grams. 
     
     
         21 . The detachable cover of  claim 18 , wherein the diameter of the cover is between about 1 cm to about 5 cm. 
     
     
         22 . The detachable cover of  claim 18 , wherein the total length of the cover is between about 4 cm to 10 cm.
