Abstract
A stepladder assembly has step assemblies mounted to its front rails using a bracket at each end of each step. Each bracket has truss anchor pocket means therein. Each truss rod is headed at both ends. The brackets are pre-assembled with a truss rod to a step before mounting the step to the rails. The truss anchor pocket in each bracket receives and abuttingly retains one of the truss rod heads. The brackets are riveted to the steps and to the rails.
Claims12
A ladder step bracket comprising a unit of material formed to provide:
- a step receiver and a ladder rail mount, said receiver and mount being at about a right angle relationship to each other;
- gusset means formed in the receiver and mount to strengthen the angular relationship between the receiver and mount;
- a pocket in said mount adjacent said gusset means to receive and retain the head of a truss rod in said pocket;
- an aperture in said receiver adjacent said mount, to receive the head of a truss rod therethrough;
- said pocket having a slot communicating with said aperture to receive a headed truss rod in the slot when the truss rod head is received in the pocket.
In a method of fabricating a ladder front, the combination of the steps of:
- mounting a truss rod to a first ladder step bracket, with a head of the truss rod positioned in a head retainer in the first bracket;
- attaching the first bracket to the bottom of a ladder step;
- mounting the truss rod to a second ladder step bracket, with a head of the truss rod positioned in a head retainer in the second bracket;
- and
- attaching the second bracket to the bottom of the ladder step.
