Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
160 words
An umbrella comprising a hollow tubular member, a bushing member press-fitted into one end of said hollow tubular member, said bushing member being of a resilient, electrical insulating material and having an axial bore extending therethrough, and a metal terminal plug press-fitted into said axial bore of said bushing member, said bushing member and said terminal plug forming a water-tight seal at said one end of said hollow tubular member, means detachably connected to said tubular member for supporting an electric lamp in electrical connection with said terminal plug, means for supporting an electrical power source near the other end of said tubular member, and an electrical conductor wire disposed in said tubular member, one end portion of said wire being adapted for connection to said power source, And the other end portion of said wire being press-fitted between the inner surface of said axial bore of said bushing member and an outer surface portion of said metal terminal plug.
Claim 2
Dependent Claim
160 words
