ABSTRACT:
The invention refers to a lifeline device which is designed to lower persons from a burning building, after evacuation through a window, distinguished by the lifeline (A) having a length which corresponds to the mounting height of the equipment above the ground over a friction pulley (B) having a circumferential groove (C), which will cause braking said lifeline is threaded to occur under the weight of the person being lowered. The friction pulley of the pulley and lifeline (B) has a centered over-dimensioned axle hub (D) and runs between two bolts (E,E') attached to the sideplates (F) forming a pulley housing, which is fastened with a bracket (G) to a window sill or other structure. Under loading, the line (A) locks the friction pulley (B) against the bolts (E,E') so that the line is pulled through the friction pulley's groove (C) and the line passes between two bolts (H) placed in the lower end of the housing (F) to hold the line within the groove (C). With the lifeline coiled up, a safety harness (I) made of a suitable soft material is fastened to the short end of the like before use. The lifeline (A) is stored in a cassette (J) fitted with a sliding lid (K) with line release (L). By pressing the lid the line is released and the cassette can be thrown out of the window. The lifeline (A) which runs across the friction pulley (B) can easily be returned to the original position when the unloaded friction pulley is freed to rotate in the reverse direction.
