Abstract
Prior apparatus for anchoring a person working within an enclosed chamber such as a manhole (10) is relatively bulky. Herein, a member (18) sits upon a periphery (14) of an overhead opening (18) to the chamber (10). A support structure (26) is attached to the member (18). An anchoring structure (32) serves for normally preventing a line (17) which is attached to a person in the chamber (10) from playing out downwardly into the chamber (10) and for allowing the line (17) to be freely drawn upwardly out of the chamber (10) with the person attached thereto. The anchoring structure (32) is mounted to the member (18). The overall apparatus (16) is relatively small and light in weight, can be used on sloped ground and allows maximal use of a rescuer's leg muscles in drawing a person out of the manhole (10).
Claims9
In an enclosed chamber (10) having an overhead opening (12) having a periphery (14), an improved safety apparatus (16) for anchoring a line (17) attached to a person and for withdrawing the line (17) and the person from the chamber (10), comprising:
- a generally planar member (18) generally centrally open and having a top portion (20) and a bottom portion (22), said member (18) being adapted to surroundingly engage a substantial portion of said periphery (14);
- a support structure (26) attached to said member (18) adjacent said periphery (14);
- anchoring means (32) for normally preventing a line (17) attached to a person in the chamber (10) from playing out downwardly into the chamber (10) and for allowing the line (17) to be freely drawn upwardly out of the chamber (10);
- and
- means (34) for mounting the anchoring means (32) to the member (18).
