Abstract:
1. A ladder guard configured for movable attachment to a ladder having elongated rails and a series of spaced apart rungs extending between the rails, the ladder guard comprising: a blocking structure comprising at least a first panel member and a second panel member, each having an upper end and a lower end, the upper end of the second panel member being coupled to the lower end of the first panel member; an upper support assembly pivotally connected to the upper end of the first panel member and including a first rung engagement mechanism for engagement with an upper rung of the series of rungs; and a lower support assembly pivotally connected to a lower end of the blocking structure and including a second rung engagement mechanism for engagement with a rung below the upper rung in the series of rungs; a means for moving the upper support assembly and the lower support assembly in unison; wherein the ladder guard is configured to move about the ladder by moving the blocking structure with respect to the upper and lower support assemblies between: a first position, in which each respective panel member of the ladder guard is located in front of a respective ladder rung to prevent access to the respective rung; and a second position, in which each panel member of the ladder guard is located behind the respective rungs of the ladder to allow access to the respective rungs; whereby the movement from the first position to the second position includes an upward component and a rearward component to move each respective panel member upward and over the respective rung while the first and second rung engagement mechanisms are able to maintain engagement with the rungs; and a locking device to releasably lock the ladder guard with the panel members in said first position.
