Abstract: The invention relates to a device for guiding a moving body (1) along a tensioned cable (4) attached at intervals to a building facade (3) and at a given distance therefrom. It comprises a pivoting device (7) formed by a pair of stars (8) parallel, coaxial and integral with one another, the points (9) of which face one another, pivoting about an axis perpendicular to the cable axis (4), the axis of the pair of stars (8) being rotationally integral with the structure of the guided moving body (1).

Abstract: A system for securing a life-line around the outside of a structure, e.g., the wheelhouse of a boat, includes attachment devices for the life-line at intermediate positions therealong (particularly at corner parts of the structure) which allow a hook of a safety line attached for sliding movement to the life-line, to pass those attachment points. In one embodiment each attachment device comprises a recessed wheel and a slipper member located to embrace tip portions of the wheel projections to be held thereby while allowing rotation of the wheel relative to the slipper member. In this way the slipper member guides the line in an arcuate path around a peripheral part of the wheelhouse to allow a hook engaged for sliding movement along the life-line to traverse the attachment point by engaging in a recess in the wheel which then rotates relative to the slipper member to pass the hook through the attachment device.

Abstract: A load transfer device is disclosed which includesa rotatable wheel which is formed with several recesses in its periphery to receive a load bearing element. The load bearing element extends transversely to the plane of the wheel and cooperates in use with the load transfer device, the recesses being evenly spaced around the wheel and adjacent recesses being separated by a projecting part of the wheel.at least one guide member is supported at a peripheral part of the wheel, the wheel and guide member having cooperating relatively rotatable surfaces to allow the wheel to rotate about its axis relative to the guide member with the load bearing element being received, guided and passed in at least one of the recesses while being located with respect to the wheel by the guide member.
