초록 ▼

A cargo tie-down device in one embodiment includes hooks and/or loops for connection to the vehicle, a buckle assembly comprising a pair of buckles, and straps which extend through the buckles and interconnect the hooks and/or loops. The straps extend a plurality of times between the buckles to provide a mechanical advantage for the tie-down device. Loops or handles on the straps allow the user to easily pull a take-up strap to initially take in the slack in the strap, and then to pull a winch strap to tightly secure the tie-down device over the load. Releasable cam locking mechanisms on the buckles normally engage the straps during the tightening process, but can be manually manipulated to release the straps to remove the tie-down device from the vehicle. In a second embodiment, the tie-down device comprises a pair of hooks for connection to the vehicle, a single buckle, and a strap which extends through the buckle and interconnects the hooks. The strap again extends a plurality of times between the buckle and one hook to provide a mechanical advantage. The buckle in the second embodiment also includes a releasable cam locking mechanism which normally engages the strap but can be manually manipulated out of engagement with the strap.
