Patent ID: 6962234

Claim:
An anchorage device for securing a workman to a flanged structural member, said anchorage device comprising: an elongated cross-member defining a plurality of longitudinally-spaced apertures, each aperture being formed within a closed-sided perimeter; first and second clamps located on said cross-member, and adapted to receive and engage respective opposing flanges of the structural member, said first clamp being slidably mounted for movement along said cross-member relative to said second clamp; a pivoted pawl attached to said first clamp at a pivot point, and comprising: a pair of teeth spaced apart along a longitudinal axis defined by said cross-member; and an engagement portion for receiving a manual force sufficient to pivot said pawl relative to said cross-member from a clamp-locking position to a clamp-releasing position, such that: i. in the clamp-releasing position, said teeth are pivoted away from said cross-member, whereby said first clamp is freely slidable along said cross-member relative to said second clamp; and ii. in the clamp-locking position, said teeth move into respective spaced apertures of said cross-member, thereby locking said first clamp in a fixed condition on said cross-member relative to said second clamp.
