Abstract
A quick attaching and quick releasing roller attachment for aerial ladders on fire fighting equipment and the like to support a rope or hose and the like on the ladder includes a pair of spaced, rung embracing channels carried by an overcenter type linkage, and rope or hose supporting rollers arranged such that in a first, expanded position of the overcenter linkage the channels are positioned adjacent a selected pair of ladder rungs, and in another, latched position of the linkage the channels are moved toward one another in secure engagement with the rungs and the rollers are disposed in a position to support the rope or hose and the like in spaced relation to the rungs.
Claims10
A quick-release roller attachment for supporting a rope or hose and the like on an aerial ladder, comprising:
- a first pair of spaced apart, substantially parallel side links;
- rung-engaging hook means carried by the side links at one end thereof;
- a pair of spaced apart, substantially parallel roller-supporting side plates pivotally connected between the ends thereof to the other ends of the side links;
- roller means carried by the side plates adjacent one end thereof and spanning the space therebetween in a position to support a rope or hose and the like thereon;
- a pair of side bars pivotally connected at one end thereof to the other ends of the side plates, and defining with the side plates and side links an over-center linkage means;
- and rung-engaging hook means carried by the other ends of the pair of side bars.
A quick-release roller attachment for supporting a rope or hose and the like on an aerial ladder, comprising:
- a pair of elongate, parallel, spaced apart side links;
- first rung-engaging hook means carried by the side links at one end thereof;
- a pair of substantially identical, spaced apart, angularly shaped side plates pivotally connected between their ends to the other ends of the side links;
- further linkage means connected to the side plates and defining with the side plates and side links an overcenter linkage means;
- second rung-engaging hook means carried by the further linkage means in spaced relation to the first hook means, for movement of the hook means relatively toward and away from one another into and out of engagement with a pair of spaced apart rungs upon operation of the overcenter linkage means to releasably support the attachment on a ladder;
- and a pair of parallel, spaced apart rollers extending between and rotatably supported on said side plates.
