发明名称 Ladder stabilizing system
摘要 A ladder stabilizer boot for providing stability to a ladder during use upon softer substrate, such as loose soil, sod, sand, or gravel, preventing the sinking of the ladder leg into the ground, causing the ladder to tilt and possibly throwing off the balance of the user, causing injury. Molded of a single element, each stabilizer boot comprises a generally planar base, with a channel for receiving and frictionally holding the bottom end of a rectangular cross-section ladder leg therewithin. Alternatively, the ladder boot may be utilized on smooth surface, wherein an anti-skid texture on the bottom of the base provides friction between the ladder leg and the surface, preventing slippage of the ladder and possible injury.
