ABSTRACT:
BACKGROUND OF THE INVENTION
Loads on rail cars need to be restrained from shifting under the various loads imposed by draft, buff, and rocking of the car. For particular types of loads, such as large rolls or coils of sheet material, or palletized loads, tensioning mechanisms using straps and anchors are advantageous. A special anchor fitting adapted to receive a corresponding anchor pin combines with a strap length controlling mechanism midway from the ends of a strap to maximize strength, ease of operation, economy in manufacture and minimize damage to rolls, coils or palletized cargo. A simple cam locking mechanism may be used instead of the prior art metal ratchet mechanism on a strap.
The invention was initially adapted to shipment of paper rolls and other rolls of material easily damages by prior art rail car wall anchors. Other cargos can be secured to advantages, particularly palletized cargo such as shrink wrapped, packaged juices, or other similarly vulnerable cargo that should be protected from contact with in-car projections during loading, transporting and unloading. Further, appropriately sized snugger straps and hooks could even be used for other materials. In other uses, other transportation devices such as over the road trailers and shipping containers continue to utilize maximum cubic volume (“high cube”) designs the ability to recess anchors also has added utility.
SUMMARY OF THE INVENTION
The invention combines several distinct elements into an improved cargo snugger strap and hook mechanism. An anchor has an “L” shaped aperture which A strap shortening device enables a two part strap to be shortened to fit the cargo load through the use of a combination of turns and bights around a three part clip having a generally oval ring with an upstanding half-oval ring portion displacing the various parts of the strap threaded thereon to increase friction to the point where the strap length can be effectively fixed under load, yet the length varied when not under load.
