  • Stabilizer for folding step ladders
    Patent number: 6902036
    Abstract: A ladder is equipped with a stabilizing device. The stabilizing device resists movements of the ladder's feet which would occur in response to movements of a ladder's user while on the ladder. The stabilizing device holds the ladder's feet and provides transverse and longitudinal structure to provide counter forces to the ladder's feet to hold the ladder's feet against movement. The stabilizing device may have rigid bars forming a box structure extending between the ladder's feet or may be formed as a solid panel. The stabilizing device may be retrofitted to existing ladders.
