The slide further includes a handle that is capable of interacting with an attached connecting mechanism. The handle is articulated relative to the body such that the handle has a freedom of rotary movement of axis in a direction perpendicular to a longitudinal axis of the guide duct and different from a direction of traction of the connecting mechanism of the handle.

Abstract: A pulley apparatus (10), includes a dram (12) having a central axis mounted between two side plates (14, 16) for receiving a rope (120) passing around the drum. The dram (12) defines a cylindrical surface for receiving a rope or line. The pulley apparatus includes holes (14a, 16a) for hanging or supporting the pulley from a hook karabiner or the like. A rope guide means (30, 32) is defined on the underside of the pulley adjacent the dram and passing over the cylindrical surface of the dram for guiding the line to wrap around the central part of the dram and inhibiting overran of ropes. The guide means comprise two curved blades (30, 32) which extend from the side plates and bow out towards the center of the dram to define a convergent-divergent wasp-waisted passage for the line to pass through. A second single, freely rotatable sheave (40) is mounted to the apparatus between the lower ends of two plates (42, 44) whose upper ends are pivotally mounted to the side plates, and hangs below the guide means in use.

Abstract: A retrofittable hook protection device for use with a hook is provided. The hook includes an intermediate portion interconnecting a hook portion and an end having an aperture, a gate for opening and closing an opening proximate the hook portion, and a lanyard operatively connected to the end proximate the aperture. The protection device includes a first and second member. The first member is configured and arranged to receive a first portion of the lanyard and a second portion of the end proximate a first side of the hook. A second member is configured and arranged to receive a third portion of the lanyard and a fourth portion of the end proximate a second side of the hook. The first and second members are connectable to sandwich the portions of the lanyard and the end there between.
