Abstract: An articulating buckle including a loop side and a hook side, the loop side configured to pivotably couple with the hook side via insertion of a cylindrical bar of the loop side into a rounded groove of the hook side. Coupling via the cylindrical bar and rounded groove enables the loop side to pivot relative to the hook side while the two sides are engaged. The articulating buckle further includes a first cam latch and a second cam latch, pivotably coupled to a base of the hook side, and configured to releasably secure the cylindrical bar within the rounded groove. The first cam latch includes a first lobe, and the second cam latch includes a second lobe, wherein the first lobe and the second lobe are configured to bias the first cam latch and second cam latch, respectively, towards a locked position, when acted against by the cylindrical bar.

Abstract: A brake bar assembly having a U-shaped frame, a sliding friction bar positioned on the U-shaped frame near a closed end of the frame, a fixed friction bar attached to an open end of the U-shaped frame, and a lockable center bar assembly positioned on the U-shaped frame between the sliding friction bar and the fixed friction bar having a spring operated locking mechanism which allows the center bar to be releasably pivoted on the frame.
Abstract: A fall arrest harness having a primary arrest attachment attached to a dorsal portion of a harness by a dorsal release strap, a releasable friction device positioned at a hip location of the harness and a repositioning tether releasably connected to the primary fall arrest attachment. The harness provides manual and controllable transfer of a suspension point from a dorsal location by letting out the dorsal release strap through the releasable friction device until tension from a user's weight is transferred from the dorsal release strap to the repositioning tether.
Abstract: A pulley is provided having a first plate and a second plate arranged adjacent to the first plate and connected to the first plate by an axle. An eccentrically mounted sheave is located between the first plate and the second plate and is adapted to freewheel in one direction only. The eccentrically mounted sheave is mounted eccentrically with respect to the axle. A fixed block is mounted between the first plate and the second plate and is adapted to fixedly lock a line between the fixed block and the eccentrically mounted sheave.
