20100014934 | METHOD FOR RETROFITTING A CHAIN TIE DOWN SYSTEM TO PARALLEL SHAFT STRAP TIE DOWN SYSTEM - A method for retrofitting chain tie down systems to strap tie down systems. Exemplary embodiments include a method for retrofitting a chain tie down apparatus to a strap tie down apparatus, the chain tie down apparatus having a central shaft, the method including affixing a first parallel shaft adjacent the central shaft and affixing shaft plates to the central shaft, wherein the first parallel shaft is radially moveable with respect to the central shaft. | 01-21-2010 |
20090241741 | VEHICLE AND CARGO TRANSPORT RATCHETING TIE DOWN APPARATUS AND SYSTEM - A ratcheting tie down apparatus and system. Exemplary embodiments include a ratcheting tie down system, including a ratchet assembly affixed to an end of a tie down shaft having a longitudinal axis, a pawl mechanism coupled to the ratchet assembly, wherein the ratchet assembly includes a ratchet gear, a ratchet head coupled to the ratchet gear, wherein an inner face of the ratchet gear is positioned in opposition to and in mechanical contact with an inner race of the ratchet head, and wherein the ratchet gear, the ratchet head and the shaft are configured to rotate as a single integral unit when rotated in a forward direction about the longitudinal axis, and the ratchet head is configured to rotate with respect to the ratchet gear and the shaft when the ratchet head is rotated in a reverse direction about the longitudinal axis. | 10-01-2009 |
20090196707 | PARALLEL SHAFT STRAP TIE DOWN APPARATUS AND SYSTEM - A parallel shaft strap tie down apparatus and system. Exemplary embodiments include a parallel shaft strap tie down apparatus and system for vehicle transports. Exemplary embodiments include a central shaft having a ratchet wheel and a pawl configured to wrap a strap around the central shaft. A parallel shaft is positioned parallel to the central shaft. The strap can be inserted between a variable gap between the central shaft and the parallel shaft. When the central shaft is rotated the strap is wound around the central shaft and the parallel shaft, both of which cooperate to create a self-tightening response of the strap on the central and parallel shafts. | 08-06-2009 |
20090196706 | PARALLEL SHAFT STRAP TIE DOWN APPARATUS AND SYSTEM - A parallel shaft strap tie down apparatus and system. Exemplary embodiments include a parallel shaft strap tie down apparatus and system for vehicle transports. Exemplary embodiments include a central shaft having a ratchet wheel and a pawl configured to wrap a strap around the central shaft. A parallel shaft is positioned parallel to the central shaft. The strap can be inserted between a variable gap between the central shaft and the parallel shaft. When the central shaft is rotated the strap is wound around the central shaft and the parallel shaft, both of which cooperate to create a self-tightening response of the strap on the central and parallel shafts. | 08-06-2009 |
