Abstract
Abstract In order to protect the electrical cables extending up through a hollow sailboat mast, the cable is inserted side-ways into a split tube made of flexible, impact-resistant material. The tube has an exterior longitudinal bead which is slid into a correspondingly-shaped keyway formed on the inside wall of the mast to hold the tube against the mast wall.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
80 words
A mast cable assembly comprising A. a hollow mast having a lengthwise keyway along its inside wall, B. a sleeve extending a substantial distance inside the mast, C. a lengthwise deflectable key affixed to the outside of the sleeve, said key slidably fitting in said keyway, and D. means for providing access into the sleeve for electrical conductors whereby, when conductors are placed inside the sleeve, they are protectively enclosed and held tightly against the inside wall of the mast.
Claim 2
Dependent Claim
80 words
A mast cable assembly comprising A. a hollow mast having a lengthwise keyway along its inside wall, B. a sleeve extending a substantial distance inside the mast, C. a lengthwise deflectable key affixed to the outside of the sleeve, said key slidably fitting in said keyway, and D. means for providing access into the sleeve for electrical conductors whereby, when conductors are placed inside the sleeve, they are protectively enclosed and held tightly against the inside wall of the mast.
Claim 3
Dependent Claim
33 words
The assembly defined in claim 1 wherein said means for providing access into the sleeve comprises a lengthwise split in the sleeve so that the conductors can be inserted sidewise into the sleeve.
Claim 4
Dependent Claim
46 words
The assembly defined in claim 2 and further including one or more openings along the length of the sleeve so that selected conductors can exit the sleeve partway along its length, and corresponding openings in the mast so that the selected conductors can exit the mast.
Claim 5
Dependent Claim
23 words
The assembly defined in claim 2 wherein the key is comprised of lips integral with the sleeve at each side of the split.
Claim 6
Dependent Claim
51 words
The assembly defined in claim 4 wherein A. the lips on each side of the split are flexible and resilient and bowed toward one another so that they form said key in the shape of a lengthwise bead, and B. the keyway inside the mast is shaped to receive the bead.
Claim 7
Dependent Claim
58 words
The assembly defined in claim 5 wherein the sleeve is formed so that A. when the sleeve is in its relaxed state, the lips are parted slightly to provide access for the conductors, and B. when the lips are retained within the keyway, they are pressed tightly together so that they resiliently engage the walls of the keyway.
