Horizontal lifeline shuttle apparatus

A horizontal lifeline shuttle apparatus, comprising:

• an attachment portion rotatable about an axis of a moveable pin and connected to a body portion by the moveable pin the body portion comprising:
• a fixed jaw having a first moveable pin groove;
• and
• a moveable jaw having a second moveable pin groove, wherein a cable channel is defined by at least a portion of the fixed jaw and at least a portion of the moveable jaw;
• wherein at least a portion of the moveable pin is disposed within the first moveable pin groove of the fixed jaw and the second moveable pin groove of the moveable jaw such that a range of motion of the moveable pin is defined at least in part by the first moveable pin groove of the fixed jaw and the second moveable pin groove of the moveable jaw;
• wherein at least one of the first moveable pin groove and the second moveable pin groove comprises a vertical portion and a first non-linear portion;
• wherein the horizontal lifeline shuttle apparatus is configurable between an open position, a closed position, and a standard position:
• the horizontal lifeline shuttle apparatus being configurable in the closed position based at least in part on a first force acting on the attachment portion in a falling direction, wherein the first force causes the moveable pin to move away from the body portion along the first moveable pin groove and the second moveable pin groove and drives the moveable jaw into the closed position, wherein the closed position is defined at least in part by the moveable jaw rotating about a fixed pin toward the fixed jaw to at least partially close a cable channel gap that is defined adjacent the cable channel between the fixed jaw and the moveable jaw;
• and
• the horizontal lifeline shuttle apparatus being configurable in the open position based at least on a two-step operation comprising a compression of a button element and a second force applied to the attachment portion in a second direction different from the falling direction, wherein the second force causes a displacement of the moveable pin that rotates the moveable jaw such that the cable channel gap is widened to a first gap length sufficient wide to allow a cable to pass into the cable channel via the cable channel gap;
• wherein the standard position is defined at least in part by the cable channel gap being arranged at a second gap length smaller than the first gap length to prevent the cable from passing therethrough, while enabling movements of a fixed jaw cable channel surface of the fixed jaw and a moveable jaw cable channel surface of the moveable jaw along respective sides of brackets holding up the horizontal lifeline shuttle apparatus.
