  • Patent number: 7137482
    Abstract: A ladder stand-off includes an extension beam and first and second stand-off sections slidingly mounted on the extension beam, so as to provide an adjustable span. Each stand-off section includes a support beam and an arm fixedly connected to the first support beam. A contact element is pivotally contacted to the outer end of each arm, allowing the device to be used with flat, curved and corner surfaces. The two arms preferably extend in an outward direction so as to be angularly divergent with respect to each other. The device can also be implemented as a ladder stand-off kit having multiple extension beams of different lengths that can be used interchangeably with the two ladder stand-off sections. In this case, the desired extension beam would be assembled with the first and second stand-off sections to form a ladder stand-off.

  • Patent number: 6962237
    Abstract: A ladder stand-off includes a beam and two arms fixedly connected to the beam at two spaced apart points between the two ends of the beam. The two arms extend outward from the beam so as to be angularly divergent with respect to each other. A contact element is pivotally connected to a second, outer end of each arm. This arrangement allows the ladder stand-off to be used with flat, curved and corner surfaces. In one embodiment, the ladder stand-off is sized so that the distance between the fixed ends of the arms is less than the width of the ladder, while the distance between the outer ends of the arms is equal to or slightly greater than the width of the ladder. Furthermore, the distance between the outer ends of the arms is less than the length of the beam.
