Abstract
A personal escape device which can be used by men, women, and children, including physically disabled persons, to descend in a controlled and secure manner from high structures such as office buildings, multistory homes, and the like. The device is designed for a relatively low-cost, small size which may be used by payloads of variable weights. The rescue device of the invention may be a single-use device or a multi-use device.
Claims14
A personal escape device, comprising:
- A. a housing having a port,
- B. a primary spool extending along a central axis and disposed within said housing opposite said port, said primary spool being rotatably coupled to said housing to permit rotation of said primary spool about said central axis,
- C. an elongated cord having a proximal end and a distal and, said proximal end being affixed to said primary spool and said distal end extending through said port, said cord including a plurality of windings around said primary spool,
- D. a secondary spool on an idler shaft extending along an idler axis parallel to said central axis, said secondary spool being rotatably coupled to said housing to permit rotation of said secondary spool about said idler axis, and said secondary spool including an elongated, circular cross-section core extending along said idler axis, said core having a lateral surface disposed about said idler axis, and wherein said cord includes at least one winding around said secondary spool between said primary spool and said port,
- E. an anchor assembly extending from said distal end of said cord, including means for selectively coupling said distal end of said cord to an external object,
- F. a payload coupler affixed to said housing for receiving a harness assembly for supporting a payload, and
- G. an unwind control assembly including centrifugal means for controlling the rate of exit of said cord from said housing to be a predetermined function of time in response to a substantially constant pulling force on said distal end.
