BACKGROUND OF THE INVENTION
Loads on railway 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.
To avoid the limitations with present practices of prior art the invention relates generally to the improvement in lading tie anchor systems for railway cars. Prior art is specific to a particular type of strap, hook, pin or anchor fitting and is limited to its own inherent arrangement. The invention combines several distinct elements into an improved cargo lading tie anchor system so as to offer the user more versatility in securing cargo.
This novel multipurpose anchor has multiple provisions and adapted to receive various different types of straps and cargo lading tie hardware that correspond to their particular attachment features.
The invention also provides a lading tie anchor system and method of using the same which can use various lading tie straps, bands, strap end pin or strap end hooks already in use and practice with various railway cars.
The anchor fitting is mountable in a wall, deck or support of a vehicle so that the fitting can be adapted to different load conditions including a different mix of lading.
DESCRIPTION OF RELATED ART
U.S. Pat. No. 6,422,794 teaches a cargo snugger strap and hook mechanism with an anchor with a “L” shaped aperture, where said system is dependant upon cargo straps and hook mechanism tailored to fit the specific “L” shaped aperture anchor. The disclosure in this patent is incorporated by reference in the instant application as if fully set forth herein.
U.S. Pat. No. 6,402,446 teaches a lading tie anchor system with a strap and a specific rigid hook body that respectively is retained and dependant upon a specifically shaped tie anchor aperture. The disclosure in this patent is incorporated by reference in the instant application as if fully set forth herein.
Application Publication No. 2003/0133767A1 published Jul. 17, 2003, shows two apertures, one for a pin and one for a plain woven strap. The unique capability of multipurpose anchor 10 allows enhanced usability for the railway car 34. Different arrangements, size and shaped lading 22 call for particular lading tie anchor system scenarios. The applicant's invention is intended to offer multiple lading tie hardware usage options so as to result in the railway car 84 being more versatile than what is disclosed within the prior art that has been previously discussed.
The forgoing prior art teaches certain parameters for lading tie anchor and lading tie strap systems and uses specific solutions to meet the needs. The instant invention departs from the limited functionality in its use of the anchors being specific to a limited selection of tie straps. Additionally, the prior art typically uses specific hardware that is dedicated for its specific use and is not versatile in its nature. The instant invention utilizes simple, yet offers an anchor with provisions to accept multiple strap configurations and not limited to the specific “L” shaped or bar shaped aperture anchor which offers a real advantage for the user so the user is not limited to usage of a limited strap hardware provision.
