Abstract

1289591 Safety devices for workmen; releasable fastenings LEBAG LEITUNGS-UND ELEKTROBAU AG 7 Oct 1970 [9 Oct 1969] 47688/70 Headings E1S and E2B A safety device for a workman comprises a hollow elongate support member 1 having a longitudinal opening, which is permanently fixed to a ladder or adjacent structure, a slide member which is displaceable along the support member 1 and has a first portion 3 held captive within the support member and a second portion 4 projecting through the longitudinal opening, and a clamping member in the form of an eccentric cam 7 pivoted on the projecting portion 4 of the slide member and having a coupling member 11 for attachment to the workman, the slide member being freely slidable along the support member in normal use, but falling of the workman causing the cam 7 to be displaced so that its operative portion 9 and the portion 3 of the slide member grip a portion 5 of the support member therebetween and prevent further movement. A spring-loaded plunger 12 is mounted in a bore 13 in the projecting portion 4 of the slide member and urges the cam 7 towards the clamping position so that, in the event of a fall, clamping takes place almost immediately. The support member may be curved, and may be of sections 1 jointed at 2. The slide member may have guide shoes 6 defining with the portion 3 guide grooves for the support member edges.
