Publication number: 20110315481Abstract: Herein is disclosed a centrifugally-operated apparatus that comprises at least a shaft with an axis of rotation and a pawl that is coaxially mounted on the shaft with at least a portion of the pawl being movable radially inwardly and outwardly from the shaft. The axis of rotation of the shaft passes through the pawl, at a location that is radially offset from the center of mass of the pawl. Rotation of the shaft and pawl above a predetermined speed can cause at least the movable portion of the pawl to be moved radially outward from the shaft, in which position an engaging end of the movable portion of the pawl may engage with a component such as a ratchet.Type: ApplicationFiled: June 23, 2010Publication date: December 29, 2011Inventors: Stephen Griffiths, Kurt D. Dietrich

Patent number: 8061483Abstract: A windage brake for a fan descender comprises a rotatable spool connected by drive belts to a fan comprising a radial flow air impeller. A line is wound helically upon the spool. A user of the fan descender puts on a harness (not shown) at the free end of the line and jumps from an elevated position. The line is thereby drawn off the spool and rotates it. The rotating spool drives the fan and also winds a power spring formed by a resilient strip. The windage of the fan regulates the descent of the jumper, the fan being accelerated to a speed at which the braking force is such that the jumper descends at a rate safe for landing on the ground. When the jumper is on the ground, he removes the harness and releases the free end of the line. The line is then automatically retrieved by the power spring and rewound on the spool.Type: GrantFiled: March 20, 2007Date of Patent: November 22, 2011Assignee: Drop Zone UK LimitedInventor: Nicholas Moriarty

Publication number: 20110278095Abstract: A fall protection arrangement including a rotatable hub and a lifeline having a first end attached to the hub and a second end for removable attachment to a user, an engagement mechanism to prevent rotation of the hub upon activation, and a braking arrangement to brake the payout of the lifeline during a fall event.Type: ApplicationFiled: May 9, 2011Publication date: November 17, 2011Inventors: Mitchell H. Hetrich, David J. Losos

Publication number: 20110220436Abstract: A fall protection system comprising a line wound onto a rotatable pulley having a centrifugal clutch which activates a gearbox which in turn drives an input shaft of a hydraulic actuator whereby the hydraulic actuator controls the rate of rotation of the pulley, and a secondary brake which slows the rotational speed of the pulley should it exceed a predetermined speed, whereby in use, the line is attached to a user to restrain a fall and then the system facilitates unwinding of the line at a controlled speed to effect descent.Type: ApplicationFiled: September 18, 2009Publication date: September 15, 2011Inventor: Stephen Green
