Abstract
A ladder step platform can be mounted on any ladder having hollow rungs extending between ladder rails. This ladder step platform is especially intended for use with conventional extension ladders. The ladder step platform includes a tread or step plate extending between opposite side plates. The spacing between side plates can be adjusted so the ladder step platform will fit ladders of different width. A support rod insertable though hollow ladder rungs pivotally supports the ladder step platform with the side plates positioned on the outside of the ladder rails. A lower adjustable rod abuts the ladder rails to hold the tread or step plate in a horizontal orientation extending beyond the sloping ladder for easy access.
Claims20
An adjustable ladder step platform pivotally mountable at different elevations on a ladder, the ladder step platform including a tread mounted between two side plates with cylindrical protruding means extending inwardly from each side plate;
- the cylindrical protruding means forming axle means insertable into a hollow ladder rung to pivotally mount adjustable ladder step platform on the ladder;
- and abutment means extending inwardly from each side plate below the cylindrical protruding means, the abutment means being positioned to engage the ladder to prevent further rotation of the adjustable ladder step platform so that the tread extends generally horizontally beyond the ladder to form a flat support surface providing a more stable support than the ladder rungs.
A ladder step platform attachable to and detachable from a ladder having hollow rungs at different elevations on the ladder to provide a more stable support for a user of the ladder, the ladder step platform comprising:
- a tread spanning spaced apart parallel side plates extending substantially perpendicular relative to the tread, each side plate having a mounting opening horizontally aligned with a mounting opening in the parallel spaced apart side plate;
- a support rod having a length greater than the spacing between spaced apart side plates, the support rod being insertable through and detachable from the aligned upper openings and through a hollow rung flanked by the two spaced apart parallel side plates;
- and
- a stop member insertable through and removable from one of a series of lower openings in at least one of the spaced apart parallel side plates, the series of openings comprising means for positioning the stop member at different distances from the support rod to adjust the angle of the ladder step platform relative to the ladder so the tread can be substantially positioned in a horizontal plane for different angular orientations of the ladder.
A step platform mountable on a ladder at any elevation opposite any hollow rung on the ladder so that the step platform extends beyond the rung and the ladder, the step platform extension comprising:
- a tread;
- side plates on opposite ends of the tread and extending below the tread, each side plate having at least one hole forming a pair of aligned holes;
- and
- a first rod means insertable through the pair of aligned holes in the side plates an opposite ends of the tread, the first rod means being located adjacent a rear edge of the tread and being elevated above a second rod means located below the tread, the first rod means being insertable through the pair of aligned holes in the side plates and into a hollow rung positioned opposite the tread, the second rod means being positioned to engage a front edge of the ladder to support the step platform extending beyond the front edge of the ladder.
