Abstract
A ladder standoff device including first and second support bracket assemblies operably coupled to a ladder, wherein the first and second support bracket assemblies are operably coupled to one another, and rotatable stabilization devices secured to respective first and second support bracket assemblies, such that the rotatable stabilization devices operably bear against a respective surface to support an upstanding portion of the ladder.
Claims21
In operable combination with a ladder, a ladder standoff device comprises:
- (a) first and second support bracket assemblies operably coupled to the ladder, said first support bracket assembly including a first ladder mounting portion integrally formed therewith, and said second support bracket assembly including a second ladder mounting portion integrally formed therewith, said first ladder mounting portion being specifically configured to be directly and matingly received within said second ladder mounting portion so as to operably engage said first and second support bracket assemblies to one another, said first and second support bracket assemblies being operably engaged with one another through one or more connection apertures formed in respective coupling bodies that are structurally connected to the ladder;
- and
- (b) stabilizing means pivotally secured to respective said first and second support bracket assemblies, such that said stabilizing means operably bear against a respective surface to support an upstanding portion of the ladder, said stabilizing means including first and second chassis members independently pivotally secured to respective said first and second support bracket assemblies such that each of said first and second chassis members freely pivot independently with respect to one another, said first and second chassis members each include one or more transaxles secured thereto and one or more swing arms connected to and interconnecting respective distal ends of said one or more transaxles on respective said chassis members.
A ladder standoff device for use with, and operably coupled to, a ladder, said ladder standoff device, comprising:
- (a) first and second support bracket assemblies having respective proximal and distal ends, respective proximal ends being specifically configured so as to be directly matingly engageable with one another through apertures in respective adapter brackets which are adapted to be operably connected to the ladder;
- and
- (b) stabilizing means pivotally secured to respective said distal ends of said first and second support bracket assemblies, said stabilizing means include first and second chassis members independently pivotally secured to respective distal ends of said first and second support bracket assemblies such that each of said first and second chassis members freely pivot independently with respect to one another, each of said first and second chassis members include a first transaxle and at least one swing arm transversely connected to respective said first transaxle at a location on said respective first transaxle spaced from said respective first or second support bracket assembly, and a plurality of wheels operably connected to said respective swing arm.
