Abstract
Abstract Telescopic guide for conducting a flexible cable between relatively moving parts. For positioning between relatively moving parts, such as an aircraft fuselage and a swingable wing connected thereto, there is provided a housing comprising telescopic parts, said housing being positioned between the relatively moving parts and conducting the cable therethrough. The cable is clamped at either end of the housing and a loop maintained in the cable in at least all positions other than the fully extended position of the telescopic housing. Pin and slot arrangements between the telescopic parts of the housing provide a positive limit to the extension of the housing and thereby assure that the housing will not be unduly extended and result in either damage to the housing or damage to the cable.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
180 words
In a telescopic guide for housing and protecting electric cable means creating the electric connection between relatively mOvable structural parts, the improvement comprising: means defining an elongated housing, said housing means consisting of a plurality of sections movable telescopically into one another and a pair of end wall means movable toward and away from each other; electrical conducting cable means mounted in said housing means and comprising at least one flexible electrically conducting cable, opposite ends of said electrically conducting cable being connected to and extending between said end wall means of said elongated housing means; and electrically conducting arcuate loop means positioned intermediate the ends of and connected in circuit with said electrical conducting cable means, the amount of cable in said loop means varying inversely proportional to the spacing between said end wall means by decreasing as said end wall means become increasingly spaced and increasing as said end wall means become closer spaced whereby said loop means permits an accomodation in the change in spacing between said end wall means due to a telescoping of said sections.
Claim 2
Dependent Claim
180 words
In a telescopic guide for housing and protecting electric cable means creating the electric connection between relatively mOvable structural parts, the improvement comprising: means defining an elongated housing, said housing means consisting of a plurality of sections movable telescopically into one another and a pair of end wall means movable toward and away from each other; electrical conducting cable means mounted in said housing means and comprising at least one flexible electrically conducting cable, opposite ends of said electrically conducting cable being connected to and extending between said end wall means of said elongated housing means; and electrically conducting arcuate loop means positioned intermediate the ends of and connected in circuit with said electrical conducting cable means, the amount of cable in said loop means varying inversely proportional to the spacing between said end wall means by decreasing as said end wall means become increasingly spaced and increasing as said end wall means become closer spaced whereby said loop means permits an accomodation in the change in spacing between said end wall means due to a telescoping of said sections.
Claim 3
Dependent Claim
13 words
The improvement according to claim 1, wherein said arcuate loop means is S-shaped.
Claim 4
Dependent Claim
94 words
The improvement according to claim 2, wherein a portion of said cable on one side of said loop means is straight and is positioned adjacent one side of said housing means and connected to one of said pair of end wall means; wherein a portion of said cable means on the other side of said loop means is straight and is positioned adjacent the other side of said housing means and connected to the other one of said pair of end wall means; and wherein said S-shaped loop means connects said straight cable portions.
Claim 5
Dependent Claim
62 words
The improvement according to claim 3, wherein said sections of said elongated housing means comprises hollow members of progressively decreasing cross section, one of said hollow members being slidingly received in an adjacent hollow member; and wherein a pair of remote hollow members have said wall means thereon; and wherein said loop means is positioned inside the arrangement of said hollow members.
Claim 6
Dependent Claim
15 words
The improvement according to claim 4, wherein said hollow members have a rectangular cross section.
Claim 7
Dependent Claim
23 words
The improvement according to claim 4, wherein said hollow members have a friction reducing coating thereon to thereby facilitate said telescoping relative movement.
Claim 8
Dependent Claim
79 words
The improvement according to claim 5, wherein a plurality of said hollow members have means defining aligned, longitudinally extending elongated slots in the side walls thereof; and wherein at last one of said hollow members is free of elongated slot means and has pin means thereon received in said aligned elongatd slots, the ends of said slots positively limiting the spacing between said end wall means in both the extended and retracted positions of said plurality of hollow members.
