Movable support for window washers and the like

An apparatus used in conjunction with a rope and harness utilized by window washers when hanging over the edge of a building having a parapet wall said apparatus comprising:

• (a) movable upright frame supported on a parapet wall be a plurality of wheels mounted thereon which engages said parapet wall and with said upright frame extending upwardly in the same vertical plane as said parapet wall to direct the line of action applied by the weight of the washer substantially downwardly into the wheels and parapet walls;
• (b) means for guiding said upright frame along the parapet wall;
• (c) a horizontal frame mounted to said upright frame proximal the top of said parapet wall such that said horizontal frame extends from the outer edge of said parapet wall inwardly of the wall in perpendicular relation thereto with said means for guiding being horizontally adjustable on said horizontal frame to accommodate varying widths of parapet walls and further supported on said wheels to maintain said upright frame on said wall;
• and
• (d) an opposing pair of vertical extension legs mounted to the upper horizontal frame inwardly of the wall, depending downwardly parallel the wall and mounted to a balance frame that is supported on an adjacent roof by a set of wheels with said vertical extension legs being adjustable to accommodate varying heights of the parapet walls.

An apparatus used in conjunction with a rope and harness window washers utilize when washing windows of buildings which have a parapet wall on the roof, comprising:

• (a) an upright frame movable along the parapet wall extending upwardly in substantially the same vertical plane of said wall with said upright frame directing the force applied by the weight of the operator downwardly into the upper surface of the parapet wall;
• (b) means mounted to said upright frame for movably supporting said upright frame on the parapet wall;
• (c) means for guiding said upright frame along the parapet wall;
• and
• (d) a ladder mounted to said upright frame such that said ladder depends below the outer edge of said wall in parallel relation to said wall.
