Abstract
A ladder is stabilized in a plurality of planes so it will not twist, slide or fall once it is in place. Telescoping legs are mounted on each side rail of the ladder, a cable system acts as a harness rail and an anti-roll bar is mounted on top of each side rail. The cable system allows the harness to be extended on an extension ladder.
Claims4
A stabilized ladder unit comprising:
- A) a ladder which includes
- (1) two side rail units, each side rail unit including
- (a) a plurality of sections which slidably fit together,
- (b) a first section which is a top section when the ladder is in use,
- (c) a second section which is a bottom section when the ladder is in use,
- (c) a longitudinal axis which extends between the first section and the second section, and
- (e) each section having an inner surface, an outer surface, a longitudinal axis which extends between the direction of the longitudinal axis, a first side edge which is an upper side edge when the ladder is in use and a second side edge which is a lower side edge when the ladder is in use, and
- (2) a plurality of rungs which extend between the two side rail units, the rungs being located in a first plane on each section of the ladder;
- B) an anti-roll unit which includes a bar mounted on the outer surface of each side rail of the first section of the ladder to extend away from the side rail on which it is mounted in a direction transverse to the longitudinal axis of the side rail on which it is mounted, the bars being located in the first plane;
- C) an anti-tilt unit which includes a telescoping leg pivotally mounted on the outer surface of each side rail of the second section of the ladder to extend at an oblique angle to side rail on which it is mounted, each telescoping leg being located in a plane that is oriented at an oblique angle to the first plane;
- D) an anti-fall unit which includes a telescoping leg pivotally mounted on the upper side edge of each side rail of the second section of the ladder to extend at an oblique angle to the side rail on which it is mounted, each telescoping leg being located in a plane that is oriented at an oblique angle to the first plane and at an oblique angle to the telescoping leg of the anti-tilt unit mounted on the side rail on which the telescoping leg of the anti-fall unit is mounted and at an oblique angle with respect to the bars of the anti-roll unit;
- and
- E) a harness unit mounted on the ladder and including
- (1) a cable housing on one side rail,
- (2) a cable guide on the outer surface of one side rail of the first section of the ladder,
- (3) a cable which extends between the cable housing and the cable guide on one side rail of the ladder,
- (4) a cable loop movably attached to the cable, and
- (5) a cable grip portion attached to the cable loop.

A stabilized ladder comprising:
- A) two side rails and a plurality of rungs extending between the side rail, the rungs being located in a first plane;
- B) an anti-twist unit which includes a bar that extends outward from each of the side rails in the first plane;
- C) an anti-tilt unit which includes a telescoping leg pivotally mounted on each side rail, each telescoping leg of the anti-tilt unit being oriented to be at an oblique angle with respect to the first plane and at an oblique angle with respect to the bars of the anti-twist unit;
- and
- D) an anti-fall back unit which includes a telescoping leg pivotally mounted on each side rail, each telescoping leg of the anti-fall back unit being oriented to be at an oblique angle with respect to the first plane and at an oblique angle with respect to the telescoping legs of the anti-tilt unit and at an oblique angle with respect to the bars of the anti-twist unit.
