In addition, the system includes a bracket for temporarily, yet securely, attaching a safety railing to a ladder.Type: ApplicationFiled: December 21, 2007Publication date: September 25, 2008Inventor: John R.

Publication number: 20080217103Abstract: An all directional ladder is provided having a base and a plurality of stair treads supported by and extending upwardly from the base at an angle. The ladder further includes a set of footpads, a retractable first and second set of wheels, and a third set of non-retractable wheels. The first and second set of wheels rotate 360° about a vertical axis to allow the ladder to be moved in any direction. A step lock assembly is positioned proximate the front of the base and a series of linkages are associated with this step lock assembly retracting the first and second set of wheels to change the ladder from a mobile position to a stationary position in which the ladder rests on the set of footpads and the third set of wheels. A kit and a method for retrofitting a ladder with an all directional movement system is also provided.Type: ApplicationFiled: March 6, 2008Publication date: September 11, 2008Applicant: TRI-ARC MANUFACTURING CO.Inventor: Eric S.

Publication number: 20080202851Abstract: Described is a ladder safety device for use with non supported ladders and methods of using such a device. The device has a cross bar and hooks extending from it. The hooks will engage the rails or a rung of the ladder and hold the cross bar tightly against the ladder rails. Legs extend in the opposite direction with feet that will sit on the structure which is commonly a roof, but could also be any structure in which a ladder extends beyond a support line.Type: ApplicationFiled: February 4, 2008Publication date: August 28, 2008Inventors: Donald R.

Publication number: 20080169154Abstract: A device for stabilizing a ladder has a clamp adapted to engage a side rail of the ladder, an arm extending from the clamp and a screw member disposed at the end of the arm. The ladder is leaned against the roof in the conventional manner and the device is positioned on the side rail of the ladder with the arm extending under the eaves. The screw member is then tightened against the underside of the roof (or against the soffit if there is one) to secure the ladder in position.Type: ApplicationFiled: January 7, 2008Publication date: July 17, 2008Inventors: Jerry Hein, Manuel George, Gerard Reposa
