Abstract

Abstract The invention provides safety equipment to enable a person to work and move freely around on deck in all weathers while being securely attached to the boat and to enable recovery of a person overboard by other crew members. The equipment comprises a life-line secured along both sides of the boat. At the intermediate attachment points the life-line is secured by latchways which allow a lanyard hook clipped onto the life-line to traverse each such attachment point. When a person goes overboard, the drag force on the lanyard causes the lanyard hook to move to the aft-most stanchion from where the person overboard is towed and removed by other crew members. In another embodiment, the person overboard is towed by pendants at the stern of the boat. A hoist is provided to haul the pendant inboard for recovery of the person overboard.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 325 words
Safety equipment for a boat, which equipment comprises: (a) a life-line for location along a peripheral portion of a boat, (b) support means for rigidly securing the life-line to a boat at a plurality of points along the length of the life-line to hold the line so as to conform to any configuration required by marine design, to which life-line a person can be attached by means of a safety harness, (c) a traversing device at each end and each intermediate attachment point of the life-line for attaching the life-line to the support means while allowing a lanyard attachment means engaged with the life-line to traverse freely each intermediate attachment point in either direction whether the wearer is inboard or overboard, each traversing device comprising: (i) a rotatable wheel which is formed with several recesses in its periphery, the recesses being evenly spaced around the wheel and adjacent recesses being separated by a projecting part of the wheel, (ii) a co-operating guide member supported at a peripheral part of the wheel, and adapted to allow rotation of the wheel about its axis with respect to the guide member while locating the life-line with respect to the wheel whereby a lanyard attachment can be received, guided and passed through the traversing device in recesses of said wheel which rotates relative to said guide member, (d) at least one towing pendant secured at a first end thereof with respect to the boat for towing a person overboard astern of the boat in a head-up position; (e) latching means at a second end of the pendant in detachable engagement with a traversing device at an end of the life-line and positioned to receive and firmly engage a lanyard attachment engaged with the life-line when such lanyard attachment reaches that traversing device when a person goes overboard, whereupon the second end of the pendant detaches from that traversing device to tow the person astern of the boat as aforesaid.
Claim 2
Dependent Claim 325 words
Safety equipment for a boat, which equipment comprises: (a) a life-line for location along a peripheral portion of a boat, (b) support means for rigidly securing the life-line to a boat at a plurality of points along the length of the life-line to hold the line so as to conform to any configuration required by marine design, to which life-line a person can be attached by means of a safety harness, (c) a traversing device at each end and each intermediate attachment point of the life-line for attaching the life-line to the support means while allowing a lanyard attachment means engaged with the life-line to traverse freely each intermediate attachment point in either direction whether the wearer is inboard or overboard, each traversing device comprising: (i) a rotatable wheel which is formed with several recesses in its periphery, the recesses being evenly spaced around the wheel and adjacent recesses being separated by a projecting part of the wheel, (ii) a co-operating guide member supported at a peripheral part of the wheel, and adapted to allow rotation of the wheel about its axis with respect to the guide member while locating the life-line with respect to the wheel whereby a lanyard attachment can be received, guided and passed through the traversing device in recesses of said wheel which rotates relative to said guide member, (d) at least one towing pendant secured at a first end thereof with respect to the boat for towing a person overboard astern of the boat in a head-up position; (e) latching means at a second end of the pendant in detachable engagement with a traversing device at an end of the life-line and positioned to receive and firmly engage a lanyard attachment engaged with the life-line when such lanyard attachment reaches that traversing device when a person goes overboard, whereupon the second end of the pendant detaches from that traversing device to tow the person astern of the boat as aforesaid.
Claim 3
Dependent Claim 132 words
Safety equipment as claimed in claim 1 wherein said latching means comprises a generally hook-shaped element which, before use of the pendant, is positioned to embrace the guide member of a traversing device at one end of the life-line which end is secured to that guide member, the hook-shaped element having a resilient latching element on a first arm of the hook-shaped element for resiliently engaging one side of that guide member with the second arm of the hook-shaped element located firmly against the opposite side of the guide member so that when a person goes overboard the lanyard attachment slides along the life-line over the guide member to which said end of the life-line is secured to be engaged by the hook-shaped element and held thereon by the resilient latching element.
Claim 4
Dependent Claim 51 words
Safety apparatus as claimed in claim 1 wherein each intermediate traversing device is mounted on a support by pivotal means adapted to allow the traversing device to topple outwardly and downwardly of a boat when the life-line is subjected to the drag force of a person overboard attached to the life-line.
