Abstract
Abstract A wire raceway member, for containing the wires which extend between a fan motor and its separate control module, is formed of a lower U-shaped portion and an upper expandable portion. An opening in the expandable portion is normally smaller than the diameter of the wires to be contained but, when temporarily expanded, the width is wider than the diameter of the wires so as to enable the insertion of the wires into the slot. The ends of the raceway have integrally formed members that are attachable to the motor and to the orifice ring, respectively, without fasteners. A radially extending portion of the grille cover is aligned with the top slot of the raceway member so as to thereby act as a cover to prevent the inflow of moisture into the raceway member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
181 words
An improved wire raceway structure of the type which contains a segment of electrical wires extending between a fan motor suspended from a central portion of an air conditioner unit and a control box located at a side wall of the unit comprising: a U-shaped bottom portion having a width which is substantially greater than a diameter of the wire such that a pair of wires can be contained therein and extend along a length thereof; a converging top portion integrally connected to said bottom portion and converging inwardly as it extends upwardly to its top end where it defines a longitudinal gap along its length, the width of said gap being normally less than the diameter of the wire to be contained but being temporarily expandable by flexing of said top portion to thereby allow insertion of the wire into the raceway structure; and wherein the raceway structure is mounted between the fan motor and an orifice ring, with the ends of the raceway structure being formed to accommodate attachment to said motor and said orifice ring without separate fasteners.
Claim 2
Dependent Claim
181 words
An improved wire raceway structure of the type which contains a segment of electrical wires extending between a fan motor suspended from a central portion of an air conditioner unit and a control box located at a side wall of the unit comprising: a U-shaped bottom portion having a width which is substantially greater than a diameter of the wire such that a pair of wires can be contained therein and extend along a length thereof; a converging top portion integrally connected to said bottom portion and converging inwardly as it extends upwardly to its top end where it defines a longitudinal gap along its length, the width of said gap being normally less than the diameter of the wire to be contained but being temporarily expandable by flexing of said top portion to thereby allow insertion of the wire into the raceway structure; and wherein the raceway structure is mounted between the fan motor and an orifice ring, with the ends of the raceway structure being formed to accommodate attachment to said motor and said orifice ring without separate fasteners.
Claim 3
Dependent Claim
20 words
An improved wire raceway structure as set forth in claim 1 wherein the structure is formed of a plastic material.
Claim 4
Dependent Claim
46 words
An improved wire raceway structure as set forth in claim 1 wherein said raceway structure is mounted to said motor by way of a pair of spaced tongues extending from a top portion of said raceway structure and extending over a supporting portion of said motor.
Claim 5
Dependent Claim
58 words
An improved wire raceway structure as set forth in claim 1 wherein said raceway structure is secured to said orifice ring by way of a notch formed on the lower side of said raceway structure, with said notch being adapted to overlay a portion of said orifice ring in a manner such that it is cradled in place.
Claim 6
Dependent Claim
158 words
In an air conditioning system of the type having a motor and a control device mounted separately on a frame structure and being interconnected by electric wires, an improved wire raceway structure comprising: a unitary member having a means for attaching it to the frame structure and including an enlarged section for containing portions of the electric wires; an expansible portion integrally connected to said enlarged portion to facilitate insertion of the wire into said enlarged portion and to assist in retention therein, said expansible portion being flexible and defining an opening which, in its unflexed condition, is narrower than a diameter of the electric wires and which, in its flexed condition, is wider than the diameter of the electric wires; and wherein the raceway structure is mounted between the fan motor and an orifice ring, with the ends of the raceway structure being formed to accommodate attachment to said motor and said orifice ring without separate fasteners.
Claim 7
Dependent Claim

Claim 8
Dependent Claim
21 words
The air conditioning system as set forth in claim 5 wherein the wire raceway structure is formed of a plastic material.
Claim 9
Dependent Claim
46 words
The air conditioning system as set forth in claim 5 wherein the wire raceway structure is mounted to said motor by way of a pair of spaced tongues extending from a top portion of said raceway structure and extending over a supporting portion of said motor.
Claim 10
Dependent Claim
58 words
The air conditioning system as set forth in claim 5 wherein the wire raceway structure is secured to said orifice ring by way of a notch formed on the lower side of said raceway structure, with said notch being adapted to overlay a portion of said orifice ring in a manner such that it is cradled in place.
