Patent number: 7963370Abstract: A personal, lightweight, high altitude rappel escape safety device is worn by an individual as a backpack and provides a safe means of lowering the individual from an elevated structure. The device comprises a structural body containing a mechanical device for slowly releasing a high strength cable. One end of the cable is secured to the structure prior to the user descending from the structure. The cable is released from a spool located inside the body and makes a circuitous path though a frictional structure. The structure contains baffles through which the cable extends. The friction caused by the pattern of release of the cable generates sufficient drag to safely lower a person from any altitude in a structure to the ground. The rate of descent may be adjusted via a braking mechanism.Type: GrantFiled: November 22, 2006Date of Patent: June 21, 2011Inventor: Byung-Sun Hwang

Patent number: 5145036Abstract: A new and improved descent retarding device having a main U shaped steel frame (7) allowing a short, light, design. There are five aluminum or steel cross bars (3) (4) (5) which act as friction retarders when the 7/16" rope (8) is attached. Two of the friction bars (4) are slotted on one end. This allows them to swing open when loading. The rope (8) slips through the space unoccupied by the open bars. The rope (8) is placed around the bars which are then pulled closed, contacting the friction bars (4) with the main frame (7). The device is now tight and ready to use. The unique combination of springs (9), handle bar (5) and adjustable self locking wing nuts (6) working in conjunction with each other make a safe, easy to use new concept in descenders. Using a handle instead of holding the rope on the descender increases balance and prevent burns.Type: GrantFiled: April 11, 1991Date of Patent: September 8, 1992Inventor: Michael Omalia

Patent number: 4470480Abstract: This manually operated conveying apparatus for lowering loads is easy to operate, light in weight and most of all it is safe for use.The apparatus has a rope made into a big loop. It is supported by a shaft with a roller inside the frame. When a load is applied to said rope it produced tension that causes the shaft housings to swing in the direction going with the load and the shafts that are fixed to the shaft housings pressed said rope against the rollers. These pressures tend to hold the rope and stop the load from going down but as the weight of the load exceeds this pressures the load goes down producing another sets of forces, the forces of friction between the rope and the rollers, between the shaft and the rope and between the roller and the shafts. The combined forces produced by the pressures and the frictions are going in the opposite direction that tend to hold and stop the load from going down.Type: GrantFiled: April 22, 1982Date of Patent: September 11, 1984Inventor: Remy B.
