Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 86 words
A cover for a trailer hitch, comprising: (a) a removable resilient body held securely in place by frictional fit with a trailer hitch; (b) a wiring connector formed integrally with said body, said wiring connector having a plurality of terminals for coupling said wiring connector to a source of electrical signals; and (c) a wiring cable connected to the terminals and extending through said body: wherein the connector is capable of coupling to the source of electrical signals when said body is removed from the hitch.
Claim 2
Dependent Claim 86 words
A cover for a trailer hitch, comprising: (a) a removable resilient body held securely in place by frictional fit with a trailer hitch; (b) a wiring connector formed integrally with said body, said wiring connector having a plurality of terminals for coupling said wiring connector to a source of electrical signals; and (c) a wiring cable connected to the terminals and extending through said body: wherein the connector is capable of coupling to the source of electrical signals when said body is removed from the hitch.
Claim 3
Dependent Claim 24 words
The cover of claim 1 wherein said resilient body defines a substantially hollow cylinder having an enclosed upper end and an open lower end.
Claim 4
Dependent Claim 35 words
The cover of claim 2 wherein said body includes an enlarged portion defining a concave recess which mates with a trailer hitch ball for holding said cover securely in position about the trailer hitch ball.
Claim 5
Dependent Claim 23 words
The cover of claim 2 wherein said body includes an internal circumferential ridge for gripping engagement with an upstanding trailer hitch ball post.
Claim 6
Dependent Claim 12 words
The cover of claim 1 wherein said resilient body defines a plug.
Claim 7
Dependent Claim 10 words
The cover of claim 5 wherein said plug is tapered.
Claim 8
Dependent Claim 88 words
A cover for a trailer hitch ball, comprising: (a) a substantially hollow cylindrical body having an enclosed upper end and an open lower end, wherein the inside diameter of said cylindrical body is slightly smaller than the diameter of trailer hitch ball; (b) an enlarged wall portion formed integrally with said cylindrical body; (c) a wiring connector held securely within said enlarged wall portion; and (d) a wiring cable connected to said wiring connector, wherein said wiring cable extends upward through the enlarged wall of said cylindrical body.
Claim 9
Dependent Claim 88 words
A cover for a trailer hitch ball, comprising: (a) a substantially hollow cylindrical body having an enclosed upper end and an open lower end, wherein the inside diameter of said cylindrical body is slightly smaller than the diameter of trailer hitch ball; (b) an enlarged wall portion formed integrally with said cylindrical body; (c) a wiring connector held securely within said enlarged wall portion; and (d) a wiring cable connected to said wiring connector, wherein said wiring cable extends upward through the enlarged wall of said cylindrical body.
Claim 10
Dependent Claim 33 words
The cover of claim 7 wherein said cylindrical body includes a concave circumferential recess which mates with the trailer hitch ball for holding said cover securely in position about the trailer hitch ball.
Claim 11
Dependent Claim 111 words
A cover for a trailer hitch convertible ball post, comprising: (a) a cylindrical body defining an axial receptacle extending from a lower end of said cylindrical body and terminating at an upper closed end thereof for removably coupling said cylindrical body to a trailer hitch convertible ball post; (b) a wiring connector securely positioned within the said cylindrical body for coupling the connector to a source of electrical signals; and (c) a wiring cable connected to said wiring connector, wherein said wiring cable extends upward through said cylindrical body and wherein the connector is capable of coupling to the source of electrical signals when said body is removed from the post.
Claim 12
Dependent Claim 111 words
A cover for a trailer hitch convertible ball post, comprising: (a) a cylindrical body defining an axial receptacle extending from a lower end of said cylindrical body and terminating at an upper closed end thereof for removably coupling said cylindrical body to a trailer hitch convertible ball post; (b) a wiring connector securely positioned within the said cylindrical body for coupling the connector to a source of electrical signals; and (c) a wiring cable connected to said wiring connector, wherein said wiring cable extends upward through said cylindrical body and wherein the connector is capable of coupling to the source of electrical signals when said body is removed from the post.
Claim 13
Dependent Claim 23 words
The cover of claim 9, wherein said cylindrical body includes an internal circumferential convex ridge for frictional engagement with the convertible ball post.
Claim 14
Dependent Claim 19 words
The cover of claim 9, wherein the lower end of said axial receptacle defines a conical inwardly tapering surface.
Claim 15
Dependent Claim 21 words
The cover of claim 11, further including a recess in said conical tapering surface for providing access to said wiring connector.
