Security device for use with a safety line

A security device for attaching a lanyard to a safety line, said device comprising:

• a frame assembly including a main frame portion and a movable frame portion comprising a pivot member pivotally mounted to said main frame portion;
• said main frame portion comprising parallel first and second side plates and a U-shaped portion connecting said side plates, said first side plate having a pivot aperture;
• a safety line channel located between said side plates and adjacent to said U-shaped portion for receiving a safety line, said safety line channel defining a channel axis extending through said main frame portion;
• said pivot member including parallel pivot member plates and including a pivot aperture formed in one of said pivot member plates, said pivot member plate pivot aperture aligned with said pivot aperture in said first side plate, such that said pivot member plate pivot aperture and said pivot aperture in said first side plate define a common, colinear axis on said main frame portion;
• a rigid, elongated fastener member extending through both said pivot member plate pivot aperture and said pivot aperture in said first side plate and extending along said common, colinear axis to define a pivot axis extending perpendicular to said channel axis;
• a cam portion supported on said movable frame portion, said cam portion comprising a cam member having a cam surface directed into said channel;
• a ring portion connected to said cam portion for connection of a lanyard thereto;
• a pair of first apertures formed through said first and second side plates and aligned along a first common axis parallel to said pivot axis;
• a pair of second apertures formed through said first and second side plates and aligned along a second common axis parallel to said pivot axis;
• first and second pin passages defined by respective first and second bushings extending through said pivot member and connected to said parallel pivot member plates;
• a first longitudinally removable pin member extending through said pair of first apertures and through said first pin passage, said first removable pin member supported for sliding movement within said first pin passage in a direction parallel to said pivot axis;
• a second longitudinally removable pin member extending through said pair of second apertures and through said second pin passage, said second removable pin member supported for sliding movement within said second pin passage in a direction parallel to said pivot axis;
• and
• wherein said pivot member is pivotally movable about said pivot axis from a closed position with said cam portion located between said side plates to an open position providing clearance between said cam portion and said side plates for passage of a safety line into and out of said channel.
