ABSTRACT:
A support device for use in forming scaffolding or for supporting a paint bucket on the rail of a ladder or the like, consists of a pair of opposed bracket members having substantially identical configurations adapted to receive the ladder support rail or post therebetween. These bracket members each include flange elements extending outwardly therefrom and located in parallel relation to each other in the operative position of the device on the support rail. A generally L-shaped support bar having first and second angularly related legs is pivotally secured to the bracket members between their respective flanges adjacent the junction between the angularly related legs by a pivot pin which extends through the flange elements and support bar, with the flange elements being generally slidable along the pivot pin. A spring member is operatively engaged between the flange elements to bias these elements apart to extreme positions along the pivot pin. In this manner the bracket elements can be urged apart, as by manually squeezing the flange elements towards each other against the bias of the spring means, in order to permit adjustment of the position of the support device on the post. In the operative position of the device one of the legs of the support bar engages the support rail below the bracket elements, and is urged into engagement with that rail by a weight, for example a bucket of paint or a scaffold beam on the other of the legs, so that the bracket elements and support bar cooperate to hold the support device in a fixed position along the support rail.
