A device that integrates an ascender with a pulley block consisting of two side plates pivotally connected to one another and selectively opened or closed, for loading a rope into a rope channel defined therebetween. Affixed adjacent the rope channel is a selectively activated rope clamp, to hold or release a rope. A sheave adapted to freewheel on an axle, is positioned offset the rope channel, and is used for mechanical advantage rigging when ascending or rescue. Also, a link connection is located at or near the sheave and is used for the attachment of a foot loop or other connection for assisting in ascending on a rope.

Device that integrates an ascender with a pulley block

Method and Apparatus for a Compact Descender used in conjunction with a rope. The invention includes a first plate and a second plate arranged adjacent to one another and pivotally connected to one another by a rope post at the top ends of the first plate and the second plate. The first plate and the second plate are selectively and pivotally opened and closed and are interlocked when closed by attachment of a carabiner through a hole in the bottom end of the first plate and an adjacent hole in the bottom end of the second plate. The first plate and the second plate include a rope channel adjacent to a lever, where the lever is pivotally attached to a pivot pin affixed to the first plate. A substantially rectangular shaped rope clamping cam is pivotally attached above the lever on the same pivot pin.

Method and apparatus for a compact descender

A combination descender, pulley, and force limiting rope brake for rope rescue has a supporting plate having a one-way pulley sheave rotatably mounted thereto for free-wheeling rotation of the sheave in only a first rotational direction. A fixed brake member is mounted rigidly to the supporting plate. A movable brake member is pivotally mounted to the supporting plate. A pinching opening is defined by the gap. The rope passes in a first direction through the gap when the sheave is free-wheeling in the first rotational direction. The movable brake member translates relative to the fixed brake member in cooperation with rotation of the sheave. Rotation-under-load of the sheave in an opposite rotational direction urges translation of the movable brake member towards the fixed brake member from an open position, wherein the pinching opening is open sufficiently to allow the rope to freely pass therethrough, to a closed position wherein the movable brake member closes the pinching opening so as to frictionally pinch the rope at a preset minimum opening of the pinching opening.
