Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
199 words
A wire duct comprising an elongated U-shaped enclosure defined by a bight portion and spaced finger portions extending normally thereto and having first locking means on an inner face thereof, a retaining clip for the retention and positioning of wires within said wire duct, said retaining clip comprising a U-shaped body defined by a bight portion and spaced leg portions extending generally normally thereto with flanges at the ends thereof, the leg portions of the U-shaped body being engageable with a first pair of opposite faces on the finger portions of said duct, the flanges on the leg portions and the bight portion of the U-shaped body being engageable with a second pair of opposite faces on the finger portions of said duct normally related to the first pair of faces, an arm extending generally perpendicularly from the bight portion of said retaining clip and laterally of said duct for retaining and positioning said wires, and second locking means on the bight portion of said retaining clip engageable with said first locking means on the finger portions of said duct to position and retain said retaining clip at a selected spacing relative to the bight portion of said duct.
Claim 2
Dependent Claim
199 words
A wire duct comprising an elongated U-shaped enclosure defined by a bight portion and spaced finger portions extending normally thereto and having first locking means on an inner face thereof, a retaining clip for the retention and positioning of wires within said wire duct, said retaining clip comprising a U-shaped body defined by a bight portion and spaced leg portions extending generally normally thereto with flanges at the ends thereof, the leg portions of the U-shaped body being engageable with a first pair of opposite faces on the finger portions of said duct, the flanges on the leg portions and the bight portion of the U-shaped body being engageable with a second pair of opposite faces on the finger portions of said duct normally related to the first pair of faces, an arm extending generally perpendicularly from the bight portion of said retaining clip and laterally of said duct for retaining and positioning said wires, and second locking means on the bight portion of said retaining clip engageable with said first locking means on the finger portions of said duct to position and retain said retaining clip at a selected spacing relative to the bight portion of said duct.
Claim 3
Dependent Claim
58 words
A wire duct in accordance with claim 1 wherein said retaining clip has a pair of recesses in the bight portion thereof situated along the lines of intersection of the plane of the bight portion and the planes of the leg portions of the U-shaped body to allow the leg portions to flex relative to the bight portion.
Claim 4
Dependent Claim
39 words
A wre duct in accordance with claim 1 wherein the second locking means on said retaining clip is movable relative to the bight portion thereof to facilitate unlocking of said retaining clip from the finger portions of said duct.
Claim 5
Dependent Claim
