ABSTRACT:
A safety assembly for stabilizing the legs of a ladder is disclosed which includes an elongated support bar, a pair of U-shaped, spaced apart, ladder leg coupling elements mounted on opposite end portions of the support bar and means, such as a pair of brackets, for attaching the support bar to a building or structure against which a ladder is to be operatively positioned. The coupling elements confine the legs of the ladder therein to prevent the ladder from tilting sideways as a person climbs off of or onto the ladder onto or off of the structure. An additional safety feature includes a pair of ladder leg snugging pins which are removably inserted laterally through the legs of the coupling elements to tightly or snuggly confine the ladder legs in the coupling elements. Still another safety feature includes a pair of pivotally movable latches which have a closed position across the otherwise open ends of the coupling elements, which latches can be swung inwardly by means of a pull cord to an open position so that the ladder legs can be removed from the coupling elements by a person standing on the ground in front of the ladder. A pair of springs bias the gates to a normally closed position against a stop member.
