ABSTRACT:
A lowering device for lowering a person or other load comprises a line for lowering the load and a support structure through which the line runs during lowering. In some modes of operation a free end of the line is secured to a fixed point, and the support structure is secured to the person and travels with the person down the line. In other modes the support structure is secured to a fixed point, and the load is secured to a free end of the line and is lowered downwardly away from the support structure. Pivotably mounted on the support structure is a transverse guide member carrying a fixed guide element at each end thereof and a rotatable guide element at the center thereof. The line passes around the guide elements and under the effect of load tension the transverse member pivots to bring the guide elements on the member into a pinching effect with guide elements which are fixed on the support structure. Variation of speed of the rope through the support structure is achieved by rotating an external lever coupled to the transverse member. The rope may follow various routes through the support structure entering and exiting at selected openings to produce different effects.
