Abstract
Abstract A cargo loading mechanism for use in the cargo compartment of aircraft having an opening in the side thereof providing access to the cargo compartment. A track is secured to the ceiling of the cargo compartment and is aligned with the opening providing access thereto. A carriage is mounted on the track for movement longitudinally therealong toward and away from the opening. A guide frame is pivotally secured to the carriage and has a support adapted to permit a depending downward movement of the guide frame externally of the aircraft from the carriage generally perpendicular to the track when the carriage is positioned adjacent the opening. The guide frame extends generally parallel to the track when it is positioned away from the opening and inside the aircraft. A lift carriage is mounted on the guide frame and is adapted to move between raised and lowered positions when the guide frame is positioned external of the aircraft.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
177 words
A cargo loading mechanism for use in the cargo compartment of a vehicle having an opening in the side thereof providing access to said cargo compartment, comprising: elongated and horizontally aligned track means secured to a ceiling in said cargo compartment and is aligned with said opening; carriage means mounted on said track means for movement longitudinally therealong in said vehicle toward and away from said opening; elongated guide frame means pivotally secured to said carriage means and including support means adapted to permit a depending downward movement of said guide frame means externally of said vehicle from said carriage means generally perpendicular to said track means when said carriage means is positioned adjacent said opening and to permit an extending of said guide frame means generally parallel to said track means when said carriage means is positioned away from said opening; and lift carriage means mounted on said guide frame means and adapted to move between raised and lowered positions when said guide frame means is in said depending relationship to transport cargo between said positions.
Claim 2
Dependent Claim
177 words
A cargo loading mechanism for use in the cargo compartment of a vehicle having an opening in the side thereof providing access to said cargo compartment, comprising: elongated and horizontally aligned track means secured to a ceiling in said cargo compartment and is aligned with said opening; carriage means mounted on said track means for movement longitudinally therealong in said vehicle toward and away from said opening; elongated guide frame means pivotally secured to said carriage means and including support means adapted to permit a depending downward movement of said guide frame means externally of said vehicle from said carriage means generally perpendicular to said track means when said carriage means is positioned adjacent said opening and to permit an extending of said guide frame means generally parallel to said track means when said carriage means is positioned away from said opening; and lift carriage means mounted on said guide frame means and adapted to move between raised and lowered positions when said guide frame means is in said depending relationship to transport cargo between said positions.
Claim 3
Dependent Claim
56 words
A cargo loading mechanism according to claim 1: wherein said track means extends transversely of the longitudinal axis of said vehicle; and wherein said carriage means includes driving means for driving said carriage means along said track means and simultaneously effecting a movement of said guide frame means between said depending and said horizontally aligned positions.
Claim 4
Dependent Claim
42 words
A cargo loading mechanism according to claim 2, wherein said support means includes winch means mounted on said vehicle adjacent said opening and aligned with said track means and an elongated cable connected between said winch means and said lift carriage means.
Claim 5
Dependent Claim
55 words
A cargo loading mechanism according to claim 3, including securement means for securing said lift carriage means to said guide frame means adjacent the lower end thereof whereby a driven movement of said lift carriage means by said winch means will effect a movement of said guide frame means between horizontally and vertically aligned positions.
Claim 6
Dependent Claim
33 words

Claim 7
Dependent Claim
31 words
A cargo loading mechanism according to claim 5, wherein said lift carriage means includes at least two individual parts which are hingedly connected together for movement between coplanar and overlapping relation.
Claim 8
Dependent Claim
44 words
A cargo loading mechanism according to claim 1, including a support bar means intermediate the upper and lower ends of said guide frame means and is adapted to be secured to said vehicle to rigidify said guide frame means when in said depending position.
Claim 9
Dependent Claim
32 words
A cargo loading mechanism according to claim 1, wherein said guide frame means includes at least a pair of laterally spaced side bars which define guide rails for said lift carriage means.
Claim 10
Dependent Claim
17 words
A cargo loading mechanism according to claim 1, wherein said lift carriage means includes conveyor means thereon.
Claim 11
Dependent Claim
15 words
