Abstract

In an aircraft cable feed out and retrieval storage apparatus, a storage compartment communicates with an assembly housing, having an inclined wall connecting between the two, with the assembly housing incorporating a base that mounts a pair of friction wheels, one of the wheels being an idler wheel, that is shiftable, and can exert pressure upon the ground cable arranged intermediate thereof, so that upon energization of a motor operatively associated with the other frictional drive wheel, the ground cable can be fed out, or retrieved, as required; the apparatus can be installed suspended to the underside of the passenger tunnel of an airline terminal, supported upon legs for mounting to the ground, or be conveyed upon wheels, and moved through actuation of a handle. The base of the assembly housing is pivotally mounted, or removable, to provide immediate access to its operating components and to facilitate their prompt servicing.

Claims

1. An aircraft ground cable handling mechanism for use in the feed out, retrieval, and storage of an electrical cable, comprising, a storage compartment, a cable moving assembly housing, said storage compartment and assembly housing being in communication with each other, said assembly housing being arranged upwardly and extending forwardly of the said storage compartment, a pair of side walls forming the side walls for both the storage compartment and the assembly housing, a common upper wall for both the storage compartment and the assembly housing connecting to the said side walls, a back wall for the storage compartment connecting to the said side walls, a bottom wall for the storage compartment connecting to the said side walls, and a front wall for the storage compartment connecting to the side walls, said front wall arranged inclined towards the assembly housing for facilitating the feed out and retrieval of the ground cable from the said storage compartment during operation of the cable handling mechanism, a cable moving assembly provided within the assembly housing and when operative functioning to withdraw said cable from the storage housing for delivery to the aircraft or retrieving said cable for return into the said storage compartment, said cable moving assembly being disposed adjacent the storage compartment and substantially aligned therewith for delivery of a quantity of cable for unencumbered storage within the said compartment or withdrawal therefrom, said cable moving assembly being supported upon a base means, said base means being shiftably mounted between said pair of side walls and capable of at least partial removal therefrom to facilitate servicing of the cable moving assembly, said cable moving assembly including a pair of friction wheels aligned for biasing against said cable when arranged intermediate thereof, one of said friction wheels being shiftable with respect to the other wheel, and pressure biased in a direction towards the same to exert a pressure against said electrical cable arranged intermediate thereof, and a motor means operatively associated with the cable moving assembly for turning of at least one of the said friction wheels to achieve the said feed out or retrieval of the ground cable.

2. The invention of claim 1 and including a storage compartment access opening provided through the said back wall.

3. The invention of claim 2 and including a cover for the said access opening, and secured to the said back wall.

4. The invention of claim 1 and including locating frame means connecting with the assembly housing and aligning the said ground cable intermediate the said friction wheels, switch means responsive to the movement of the said locating means, whereby upon actuation of the locating means effecting actuation of the switch means for curtailing operations of the motor means and terminating further retrieval of the ground cable into the storage compartment.

5. The invention of claim 4 and including another switch means responsive to the feed out of the ground cable and terminating further dispensing of the stored cable from the stogage compartment as the cable end approaches.

6. The invention of claim 1 and wherein said cable moving assembly supported upon the base means, being pivotally connected with the pair of side walls of the said assembly housing and storage compartment to accommodate its shifting to facilitate the servicing of said cable moving assembly.

7. The invention of claim 2, and including hinge means secured to the base means of the cable moving assembly, and also connecting with the side walls to accommodate the pivotal movement of the base means for attaining access to the cable moving assembly to facilitate its servicing.

8. The invention of claim 1 and wherein said cable moving assembly and its base means being slidably disposed with respect to the said side walls to accommodate the shifting of the said base means to facilitated the servicing of the said cable moving assembly.

9. The invention of claim 8 and including fastener means securing said base means to the assembly housing.

10. The invention of claim 8 and including angle means provided proximate the bottom of the side walls of the assembly housing, and said angle means supporting said base means and cable moving assembly with respect to the assembly housing.

11. The invention of claim 1 and wherein said mechanism being employed in conjunction with the passenger tunnel of an airline terminal, bracket means securing to the common upper wall and provided for connecting the cable handling mechanism suspended to the underside of the said tunnel.

12. The invention of claim 1 and wherein said mechanism being installed with respect to the ground, supports securing with the storage compartment and useful for stably mounting the mechanism upon the ground.

13. The invention of claim 1 and wherein said mechanism being portable, a series of wheel means rotatably mounted to at least said storage compartment and disposed for facilitating the wheeled movement of said cable handling mechanism.

14. The invention of claim 13 and including handle means securing with said storage compartment and provided for facilitating the wheeled movement of the said cable handling mechanism.

15. The invention of claim 14 and including brake means operatively associated with at least one of the wheel means and when engaged preventing the wheeled movement of the cable handling mechanism.

16. The invention of claim 15 and wherein said handle means incorporating bracket means whereby upon actuated movement of the handle means causes said brake means to engage the wheel means for preventing movement of the cable handling mechanism.

17. The invention of claim 16 and wherein the upward actuation of the handle means provides for wheel means engagement by the brake means.

18. The invention of claim 17 and wherein the upward actuation comprises a pivotal upward movement of the handle means.

19. The invention of claim 17 and wherein the downward actuation of the handle means releases the brake means.

20. The invention of claim 1 and including an electrical circuitry panel compartment provided proximate the back wall of the storage compartment.

21. The invention of claim 1 and wherein said friction wheels being normally spaced apart a dimension less than the diameter of the ground cable being handled, thereby exerting force upon the ground cable and to frictionally achieve its movement during feed out and retrieval.

22. The invention of claim 21 and wherein one of said friction wheels being shiftable laterally with respect to the cable to provide clearance for installation and removal of the cable during servicing.

23. The invention of claim 22 and including clamp means operatively associated with the base means and when engaged biasing the said shiftable friction wheel towards the said cable.

24. The invention of claim 23 and including spring means structured within the clamp means and urging the said shiftable friction wheel towards the other friction wheel for biasing against the said cable.

25. The invention of claim 24 and including an axle for the said shiftable friction wheel, there being a slot provided through the base means, and said axle extending therethrough, a mounting means for the said axle and stabilizing it upon the said base means for shifting within its said arranged slot, whereby upon actuation of the said clamp means exerting a bias against the shiftable frictional wheel and urging it towards the said contiguous cable.
