Definitions

  • This invention relates to a safety harness including a line for attaching the harness with respect to a fixed structure.
  • safety harness is used herein to include articles of apparel, e.g. a jacket, which can act as a safety harness when secured by a line with respect to a fixed structure.
  • British Patent Specification No. 2,024,749 illustrates such a system for use on a yacht, the system being adapted to allow free sliding movement of the lanyard attachment along a peripheral life- line -past intermediate support points thereof.
  • a retaining device for location on or associated with said means providing said eyelet, the retaining device having parts one on each side of the eyelet for receiving and locating a portion of a respective one of said connector devices, when not in use.
  • the retaining device may comprise a housing having housing portions one on each side of the eyelet for receiving and locating therein a portion of a respective one of said connector devices.
  • Each housing portion may have resilient retaining means projecting inwardly thereof for engaging and retaining the respective connector device when it is engaged in that housing portion.
  • the housing is made of resilient, preferably plastics, material and is formed with an inward depression in a side wall of each housing portion thereof to form said resilient retaining means.
  • each housing portion Preferably a pair of opposed inward depressions are formed in opposite side walls of each housing portion.
  • the housing may have a slot in a side wall or in each of a pair of side walls thereof to receive said means on the harness providing said eyelet in order to mount the housing thereon.
  • An advantage of safety apparatus is that during use it can obviate the unattached length of trailing lanyard as in the system described above using two lanyards and, in preferred embodiments, the connector device not in use at the time being, is conveniently stowed.
  • Safety apparatus is readily suitable for use in combination with a load-transfer device as described in British Patent No. 1,582,201 and, for marine applications, in conjunction with safety equipment as disclosed in and as claimed in any claim of British Patent No. 2,024,749.
  • the disclosures in these British Patents are included herein by reference.
  • safety apparatus comprises a lanyard or other attachment line (10) having secured to each of its free ends a safety hook connector (11,12).
  • the lanyard (10) passes through an eyelet which is provided for example by a "D" ring, shackle or hook (13) or any similar attachment device through which the lanyard can pass easily, and is connected to a safety harness or a jacket, the relative dimensions of the eyelet (13), lanyard (10) and hooks (11,12) being such that the lanyard can run freely through the eyelet (13) but the hooks (11,12) will not pass through the eyelet (13).
  • the apparatus further includes a hook grip (14) as shown particularly in Figure 2.
  • the hook grip (14) comprises a moulded plastics housing having a generally oblong cross-section which narrows progressively towards the centre of the housing to form a "bow-tie" shape. Pairs of depressions (15,16) are formed in side walls of the housing (14) adjacent respective opposite ends thereof, the depressions projecting towards each other inwardly of the housing.
  • the wearer of the harness fitted with the safety apparatus attaches himself to a safety line using one of the safety hooks (11,12) at an end of the lanyard (10), the other hook being conveniently stowed in the hook grip (14) as shown in Figure 3.
  • the safety hook (11) is retained in the hook grip (14) by the corresponding pair of depressions (16) which are resiliently sprung apart as an end portion of the hook (11) is engaged in the respective end of the hook grip (14) to then assume their original position on further insertion of the hook (11) into the hook grip thereby providing a positive restraint of the hook until sufficient force is applied thereto to once again resiliently deform the depressions (16) of the hook grip.
  • the hook (11) stowed in the hook grip (14) is withdrawn therefrom and clipped to the safety line on the opposite side of the second person.
  • the originally connected hook (12) is then released and stowed in the opposite end portion of the hook grip (14) to complete the passing operation.
  • FIG. 1 illustrates such a system.
  • a wire safety line (20) is suspended by U-shaped clips (21) and a load-transfer device (22) is engaged for sliding movement along the wire (20) and is capable of traversing the clips -(21) without becoming detached from the wire (20).
  • the load-transfer device comprises two wheels (23,24) having an annular series of spaced apart radial projections- (25,26); the wheels (23,24) being mounted for free rotation on a common axle (27) in a spaced apart relation.
  • a connector element (28) is mounted to extend between the wheels for free pivotal movement on the axle (27) and has an aperture (29) for receiving the hook connectors (11,12) of the apparatus of Figures 1 to 5.
  • a slipper member (30) is positioned between the wheels at a peripheral part thereof.
  • the slipper member has arcuate flanges (31) on opposite sides thereof for engaging in recesses (32,33) in the wheels (23,24) respectively such that the wheels can rotate with respect to the slipper member without becoming detached therefrom.
  • the load-transfer device (22) When during sliding movement along the wire (20) the load-transfer device (22) encounters a supporting clip (21) for the wire, the vertical limbs of the clip engage a pair of projections (25,26) of the wheels, respectively, causing the wheels to rotate relative to the slipper member (30) thereby allowing the clip (21) to pass through the load-transfer device (22) while the slipper member (30) remains in engagement with the wire (20). In this way the load-transfer device can traverse the supporting clips (21) without becoming detached from the wire (20).
  • Figure 7 illustrates diagrammatically a procedure for two persons to pass one another, each person being attached to a safety wire (20) by a safety apparatus as shown in Figures 1 to 5 used in conjunction with load-transfer devices as shown in Figure 6.
  • Figure 7A illustrates two load-transfer devices (22) engaged with the same safety wire (20) and each person is attached with respect thereto by a respective lanyard (10) with each safety hook thereof hooked through the aperture ( 29 ) in the connector element ( 28 ) of the device (22) and with the second hook (12) stowed in the hook grip of the apparatus as shown in Figure 3.
  • the second set of hooks (12) are removed from their hook grips (14) and clipped onto the connector element ( 28 ) of the opposite load-transfer device (22) so that, at that moment, the lanyard (10) associated with each person is clipped onto both load-transfer devices (22).
  • the first set of hooks (11) are released from the load-transfer devices (22) allowing the persons to carry on in their desired directions as shown in Figure 7D with the first set of hooks (11) being stowed in the respective hook clips (14) as illustrated in Figure 3.
  • safety apparatus as illustrated in Figures 1 to 5 can be used to allow a person attached by one lanyard hook to a first strong point or fixed structure to transfer to a second strong point or fixed structure without complete detachment of both such strong points or fixed structures even momentarily.
