  • Patent number: 5533591
    Abstract: A ladder rail cap comprising a shell. The shell has an inside surface defining a chamber into which a ladder rail is disposed. The shell has a top end and a bottom end having an opening in communication with the chamber. The ladder rail cap is also comprised of a clip attached to the inner surface of the shell near the top end of the shell. The clip mates with an end cap of the ladder rail and penetrates the ladder rail's envelope to hold the shell onto the rail. The present invention pertains to a ladder. The ladder comprises a first side rail having an end cap and defining a rail envelope. The ladder is also comprised of a second side rail having an end cap adjacent and in parallel to the first side rail. The second side rail defines a rail envelope. The ladder also comprises at least a first rung connected to the first side rail and the second side rail. Additionally, the ladder comprises a ladder rail cap disposed on each side rail.

  • Patent number: 5154255
    Abstract: A ladder shoe for providing enhanced stability between a ladder and a variety of surfaces. The ladder shoe is comprised of a shoe body having a first side plate, a second side plate and a base. The first side plate and the second side plate are attached to the base. The side plates include curved slots through which a fastener is disposed which movably connects the ladder shoe to the end of the ladder's side rail, thereby allowing the ladder shoe to move between a first position where the base is at a first angle with respect to the side rail and a second position where the base is at a second angle with respect to the side rail. Each slot has a notch in which the fastener catches causing the shoe to be maintained in an intermediate position until the shoe body is desired to be placed into another position. The base has a bottom which provides a slip resistant surface for engaging the shoe body to essentially flat surfaces when the shoe body is in the first position.
