    Abstract: A load balancing descending device for controlling the descent of a user descending on a rope carrying a load is provided. The rope has a decreasing rope free end as the user descends. The load balancing descending device comprises a first plate and a second plate. A first pin is positioned between the first plate and the second plate with the first pin spacing the first plate from and pivotally connecting the first plate to the second plate and the combined first plate and second plate having a first side and a second side. A second pin is positioned between the first plate and the second plate with the second pin spaced from the first pin. An attachment mechanism is formed in the first side of the combined first plate and second plate for attaching a user and/or load. The rope is wrapped in a serpentine manner about the first pin and the second pin between the first plate and the second plate with the rope free end exiting the combined first plate and second plate from the second side.

  • Patent number: 8733504
    Abstract: 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.

  • Patent number: 8701840
    Abstract: A self-belay device for controlling climbing and descending along a rope. The self-belay device comprises a hollow casing, a linear frictionless track fixed inside the casing and a braking unit disposed in the casing and mounted on the track for reciprocating sliding movement along the track between a first position and a second position. The braking unit is normally biased to the first position. The braking unit has a passage there through for passing of the rope. The rope is moveable through the passage in the braking unit in the first position, while the movement of the rope through the passage in the braking unit prevented in the second position thereof.

  • Patent number: 8678134
    Abstract: A lightweight safety harness comprises adjustable belt sections for the upper chest, waist and upper thighs. In one of two shoulder straps, there is stored a primary release pin and secondary brake strap. The shoulder straps criss-cross to form a soft, triangular shaped panel on the harness wearer's back. A spine brace divides that triangle in two. Near the top of that spine brace is a rack having at least one aperture wrapped with Kevlar® webbing. A long nylon rope serpentines back-and-forth, between sets of elastic loops running down opposed legs to the triangular panel before being threaded through the rack in a preferred pattern. At the base of that triangular panel, there is attached one end to a reserve suspension relief strap (RSRS). A cover extends the triangular panel but can be removed for inspection before every use.

  • Publication number: 20140041960
    Abstract: A descender device, typically for use in a fall arrest system, for enables a suspended body to be lowered, and includes a descent line and a release element to be actuated by a person. The release element is arranged in a restraint configuration to inhibit the descent line from being deployed and in a release configuration to permit the descent line to be deployed. A restraint arrangement is arranged prior to deployment of the descent line, to clamp or pinch a length of flexible line thereby to inhibit deployment of the descent line, the restraint arrangement being reconfigurable upon release of the release element to permit the descent line to be deployed.

  • Patent number: 8616333
    Abstract: A descent control device is disclosed manufactured with a bar having holes for guiding a rope used in descent, and a lever designed to pivot or move relative to the bar and compress the opening of one of the holes. Compressing the opening increases friction and slows or stops descent. Control can be from manually moving the lever or by connecting the lever to the descending weight, thereby automatically moving the lever. Hole and pivot geometry may be altered to provide multiple braking options, accommodate varying ropes, and alter normal operating friction.

  • Patent number: 8522918
    Abstract: The rescue harness is a personal use device for donning by an individual requiring escape from an elevated location in a building structure or the like. The harness includes a front latch and bracket having a removable combination glass cutter and hammer, and a removable explosive charge. A rope brake is also secured to the bracket, and a rope passes through the brake. The user of the harness removes the glass cutter and hammer combination, and scribes an opening on a glass window panel. The explosive charge is placed on the glass in the scribed area. A timer permits the user to momentarily leave the immediate vicinity. The hammer is used to break out any remaining glass shards after the explosion blows out the scribed area of glass. The user exits the structure through the hole in the panel, using the rope brake to control his or her descent.

    Abstract: The disclosed subject matter relates to an apparatus so designed that when properly used may aid in the prevention of injury and or even death. This device is so designed that a fallen hunter is left hanging facing the tree, allowing mobility and movement. With the attached (DOWN E-Z) device, one may lower himself to the ground with little or no effort. This final step is very important due to the documented factual records of hunters dying while being left hanging for hours and blood begins to clot.
