发明名称 Lineman's safety strap assembly
摘要 A lineman's safety strap assembly is intended for attachment to a body belt. An elongated strap terminating in a buckle at one end for varying the length of the safety strip is provided with a first hook for coupling the safety strap to the body at the other end. A second hook for coupling the safety strap to the body belt is slidably mounted on the safety strap. An inclined sharp edged roller is slidably mounted on the safety strap for movement toward the midpoint of the strap. A cross belt terminating in spring-backed latches at both ends may be slidably coupled to the safety strap at two locations in order to form a closed loop for encircling the pole with the rollers facing inwardly. In the event of a fall, the cross belt bears against the inner face of the pole and the safety strap jams in the latches, while the lower edge of the roller is pulled into biting engagement with the outer face of the pole. The lower edges of the latches may also dig into the face of the pole. The assembly thus provides a braking feature in the event of a fall, but the configuration of the roller is such that it does not hinder the lineman in ascending or descending a wooden utility pole when the braking feature is not needed.
