Ladder Mounted Brush Apparatus

US Patent:
8191684, Jun 5, 2012
Filed:
May 18, 2010
Appl. No.:
12/782151
Inventors:
David R. Dammann - Port Orchard WA, US
International Classification:
A46B 15/00
US Classification:
182129, 15161, 15237
Abstract:
The ladder mounted brush apparatus provides for ladder safety with a removably mounted device that affixes to the lower rung of a ladder, adjacent to the ladder rail. Upon beginning to climb the ladder, a user steps downwardly on the brush bristles and base to position the base and bristles atop the rung, moving the base and bristles and attachment plate from parallel to the ladder rail to a position atop the rung, perpendicular to the rail. The user then weights alternates feet to scrub footwear soles, thereby cleaning the footwear to ensure against slipping on the ladder rungs. Upon cessation of use, the attachment plate with attached brush base with bristles automatically returns to a position immediately adjacent to the ladder rail, thereby out of the way of ladder ascension and dissention.
