Abstract
Abstract A quickly removable (or installable) modular cargocarrying system for use in vehicles such as aircraft, trucks, and the like, of the type having structural floor members and rollermounted cargo supporting floor panels therebetween. The system is especially useful in applications where the cargo containers are of such dimensions that they may not extend from one structural floor member to another. The system includes relatively lightweight roller trays having spring loaded or resilient mountings whereby cargo containers are supported by the roller trays about one-eighth inch above longitudinal and transverse beams of the system, the beams picking up the load exerted by the cargo containers and transfer it to the structural floor members when the resilient roller tray mounts bottom-out upon being subjected to a predetermined load. The longitudinal beam assemblies incorporate foot operated locks for restraining the containers under the required operating conditions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
207 words
A load-carrying system for vehicles carrying cargo containers and having floor structure including a major axis, a minor axis and a plurality of spaced-apart rails secured to said floor structure substantially parallel to said major axis, said rails being spaced apart by a distance greater than the width dimension of the cargo containers measured along said minor axis, said load-carrying system comprising: at least two transverse beams; first fastening means connecting said transverse beams to said rails substantially normal thereto, said first fastening means maintaining said transverse beams in spaced-apart relationship and above said floor structure; at least two longitudinal beams; second fastening means connecting said longitudinal beams to said transverse beams substantially normal thereto, said second fastening means maintaining said longitudinal beams in spacedapart relationship and above said floor structure, said longitudinal beams being spaced to coincide with the width dimensions of the cargo containers; stop means provided on at least some of said longitudinal beams for maintaining a cargo container in position thereon; and means normally supporting said container in spaced relationship above said longitudinal beams, said supporting means including resilient means which carry a predetermined load imposed by said container, said resilient means transferring loads exceeding said predetermined load directly to said longitudinal beams.
Claim 2
Dependent Claim
207 words
A load-carrying system for vehicles carrying cargo containers and having floor structure including a major axis, a minor axis and a plurality of spaced-apart rails secured to said floor structure substantially parallel to said major axis, said rails being spaced apart by a distance greater than the width dimension of the cargo containers measured along said minor axis, said load-carrying system comprising: at least two transverse beams; first fastening means connecting said transverse beams to said rails substantially normal thereto, said first fastening means maintaining said transverse beams in spaced-apart relationship and above said floor structure; at least two longitudinal beams; second fastening means connecting said longitudinal beams to said transverse beams substantially normal thereto, said second fastening means maintaining said longitudinal beams in spacedapart relationship and above said floor structure, said longitudinal beams being spaced to coincide with the width dimensions of the cargo containers; stop means provided on at least some of said longitudinal beams for maintaining a cargo container in position thereon; and means normally supporting said container in spaced relationship above said longitudinal beams, said supporting means including resilient means which carry a predetermined load imposed by said container, said resilient means transferring loads exceeding said predetermined load directly to said longitudinal beams.
Claim 3
Dependent Claim
25 words
A load-carrying structure as stated in claim 1 wherein said stop means are carried by said longitudinal beams and are located intermediate said transverse beams.
Claim 4
Dependent Claim
28 words
A load-carrying structure as stated in claim 1 including foot-operated retraction means connected to each stop means for retracting said stop means from a normally extended cargo-restraining position.
Claim 5
Dependent Claim
28 words
A load-carrying structure as stated in claim 3 including latch means engageable with said retraction means for locking said retraction means in a depressed non cargo restraining position.
Claim 6
Dependent Claim
24 words
A load-carrying system as stated in claim 1 wherein said means normally supporting said container includes a roller tray having rollers supporting said container.
Claim 7
Dependent Claim
32 words
A load-carrying system as stated in claim 5 wherein said resilient means is an elastomeric means carried by saId roller tray and engaging said floor structure to support said predetermined load thereon.
Claim 8
Dependent Claim
51 words
A load-carrying system as stated in claim 5 wherein said container includes a bottom portion resting directly on said rollers and edge rails extending over said longitudinal beams in spaced-relationship therewith, said edge rails being adapted to bottom-out on said longitudinal beams when said resilient means transfers said load directly thereto.
Claim 9
Dependent Claim
27 words
A load-carrying system as stated in claim 5 wherein said resilient means comprises resilient washers transferring said predetermined load from said roller tray to said transverse beams.
Claim 10
Dependent Claim
83 words
A load-carrying system as stated in claim 5 wherein said roller tray includes four corners and wherein said resilient means comprises: a load pin carried by each of said roller-tray corners; a support fitting assembly supporting each of said load pins; and resilient washer means rockably connecting each support fitting assembly to one of said transverse beams, whereby said load which exceeds said predetermined load will rock said support fitting assemblies to a position wherein said container bottoms out on said longitudinal beams.
