Abstract
A self-retracting lifeline assembly (10) includes a housing (12), a shaft (14) fixed to the housing (12) against rotation, a drum (18) mounted for rotation on the shaft (14) and including a compartment (20) within the drum (18), a lifeline (22) wound on the drum (18), a brake module (24) carried on the shaft (14) and mounted within the compartment (20), and a pawl mechanism (26) mounted on the drum (18) for rotation therewith. The pawl mechanism (26) is mounted within the compartment (20) and configured to selectively engage the brake module (24).
Claims20
A self-retracting lifeline assembly comprising:
- a housing;
- a housing cover piece;
- a shaft having a proximal end and a distal end, the shaft fixedly coupled at the proximal end to the housing, thereby preventing rotational motion of the shaft relative to the housing;
- a spring carried on the shaft;
- a drum comprising a pawl mechanism, the drum supported upon the shaft at a position distal the spring, the drum configured to retain a lifeline for selective deployment and retraction and
- a brake module carried on the shaft at a position distal the spring and distal the position at which the drum is supported on the shaft, wherein the brake module can be disposed to and removed from the shaft via the distal end without moving the spring relative to an axial direction of the shaft.
A self-retracting lifeline assembly comprising:
- a housing;
- a housing cover piece;
- a shaft having a proximal end and a distal end, the shaft fixed at the proximal end to the housing such that rotation of the shaft relative to the housing about a central axis of the shaft is prevented;
- a spring carried on the shaft;
- a drum comprising a pawl mechanism, the drum supported upon the shaft at a position distal the spring, the drum configured to retain a lifeline for selective deployment and retraction, the spring configured to apply a rotational force to the drum relative to the shaft and
- a brake module carried on the shaft at a position distal the spring and distal the position at which the drum is supported on the shaft, the drum extending radially from the shaft and axially towards the distal end of the shaft such that the drum extends substantially about the brake module, the brake module being configured to be slidably removed from the distal end of the shaft, wherein the brake module can be disposed to and removed from the shaft via the distal end without moving the spring relative to an axial direction of the shaft.
