Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
184 words
A bolt cover assembly for covering the exposed end of a holddown bolt and nut for a toilet fixture, the assembly comprising: a cap having a hollow cylindrical body member, a top enclosing one end of said body member, a first groove in said body member spaced upwardly from the open end a distance greater than the height of the nut, and a second groove in said body member between said first groove and the open end of said member, and a resilient disc having a central hub, a flange extending radially outward from said hub a distance greater than the inner diameter of said cylindrical body member and a central opening in said disc having a diameter less than said bolt, said second groove being spaced inwardly from the open end of said member a distance substantially equal to the thickness of the central hub, whereby said disc is adapted to be mounted on said bolt on either side of the nut and said cap can be mounted on said disc with said flange seated in one of said first or second grooves.
Claim 2
Dependent Claim
184 words
A bolt cover assembly for covering the exposed end of a holddown bolt and nut for a toilet fixture, the assembly comprising: a cap having a hollow cylindrical body member, a top enclosing one end of said body member, a first groove in said body member spaced upwardly from the open end a distance greater than the height of the nut, and a second groove in said body member between said first groove and the open end of said member, and a resilient disc having a central hub, a flange extending radially outward from said hub a distance greater than the inner diameter of said cylindrical body member and a central opening in said disc having a diameter less than said bolt, said second groove being spaced inwardly from the open end of said member a distance substantially equal to the thickness of the central hub, whereby said disc is adapted to be mounted on said bolt on either side of the nut and said cap can be mounted on said disc with said flange seated in one of said first or second grooves.
Claim 3
Dependent Claim
49 words
The assembly according to claim 1 including a flange on the inside surface of said member, said flange forming a continuation of the upper surface of said first groove and having an inner diameter smaller than the inner diameter of said member to form a seat for said disc.
Claim 4
Dependent Claim
48 words
The hold-down bolt cover assembly according to claim 1 including a rib on the inside surface of said cylindrical body member and a groove in the outer periphery of said disc whereby said disc is restricted from rotation relative to said body member when mounted on said groove.
Claim 5
Dependent Claim
21 words
The cover assembly according to clAim 1 wherein said cylindrical body member is formed as a unitary member from plastic material.
Claim 6
Dependent Claim
187 words
In combination with a hold-down nut and bolt assembly for a toilet fixture, the assembly including a bolt having a threaded end extending beyond the nut, a cover assembly for the nut and threaded end of the bolt comprising a cap having a cylindrical side wall, a closed end and an open end, a first groove on the inside surface of said side wall spaced from the open end of said cap a distance greater than the height of the nut and second groove on the inside surface of said side wall spaced inwardly from the open end of said cap a distance less than said first groove, and a disc having a central hub, a flange extending outwardly from the outer portion of said hub a distance greater than the inner diameter of said cylindrical side wall and a central opening in said hub smaller than the outer diameter of the threaded end of said bolt whereby said disc can be mounted on said bolt and said cap can be mounted on said disc with the disc seated in one of said first and second grooves.
Claim 7
Dependent Claim
