  • Patent number: 9248323
    Abstract: A portable fall prevention apparatus. The apparatus provides points of attachment for a tether line to which a safety harness worn by a workman on a sloped roof can be attached. A pair of grapples attach to opposite, overhang portions of a sloped roof. A tie down strap threaded through a ratchet tie down connects each of the grapples to oppositely-disposed, oppositely-directed hinge plates of an anchor assembly. With the anchor assembly placed transversely across the ridge of a sloped roof and the tie down straps tightened to eliminate slack therein, the anchor assembly provides a secure point of attachment for a tether line.

    Abstract: A truck (136) has a sleeper cab (138) in which a bunk (140) is elevated from a floor (72) of the cab. A cabinet (110) is adjacent an end of the bunk. A track (146, 148) runs on the cab floor from inside the cabinet to outside the cabinet. A set of stairs (42; 242) are movable along the track from a non-deployed position inside the cabinet to a deployed position that allows a person to ascend and descend the stairs for climbing up into and climbing down from the bunk. A releasable locking system (150) locks the stairs in the deployed and non-deployed positions. A handle (158) can be pulled to unlock the stairs from non-deployed position and move them to deployed position. The handle can be pushed to unlock the stairs from deployed position and move them to non-deployed position.

    Abstract: A ladder support system, comprising a free-standing frame having an upper and lower horizontal member, and a ladder that is supported on the upper horizontal member and lower horizontal member. The frame further has a pair of ends which each have two legs joined by a top joint which forms an acute angle between the two legs which are both perpendicular to the upper horizontal member, which is also attached to the top joint. The upper horizontal member is parallel to the lower horizontal member. The ladder has wheel assemblies which engage the upper horizontal member and lower horizontal member so that the ladder may move laterally along the frame. A movement mechanism comprises a pair of end pulleys located at the ends, and a rope having a pair of rope extremities. The rope is threaded through the end pulleys with the rope extremities available to a workmen on the ladder, so that the workmen can move the ladder laterally along the frame without climbing down the ladder.

  • Patent number: 5065838
    Abstract: A movable support structure from which a window washer is suspended that utilizes the parapet wall of a building as a support or runway by directing the force applied by the weight of the washer downwardly into the parapet wall. An upright frame above the parapet wall extends upwardly in substantially the same vertical plane of the parapet wall. The upright frame is supported on the parapet wall by a first set of wheels that rest on the wall. The upright frame may be further maintained on the roof by a second set of wheels that rest on the roof. The wheels roll along the roof and wall to facilitate horizontal movement of the apparatus. The horizontal movement is guided by internal and external guide rollers that engage the respective surfaces of the parapet wall. In addition, a ladder depends over the edge of the wall such that a window washer may safely step over the parapet wall and into a position to begin cleaning.
