Abstract
A telescoping ladder includes a stabilizer connected to a stabilizer housing proximal to the floor surface on which the ladder is positioned. The first stabilizer can move between an extended position and a collapsed position. In the extended position, the first stabilizer extends out of a hollow body portion of the stabilizer housing and collapse into the hollow body portion of the rung in the collapsed position. The stabilizer comprises a locking button to lock the stabilizer in its extended position. The ladder comprises a flange that can release the locking button thereby unlocking the stabilizer from its extended position and move it into the collapsed position.
Claims15
A telescoping ladder, comprising:
- a first stile,
- a second stile, the first and second stiles each having
- a plurality of columns disposed in a nested arrangement for relative axial movement in a telescopic fashion along an axis of the plurality of columns between an extended position and a collapsed position, wherein,
- a first column of the first stile and a second column of the second stile each having a hollow body, the first and second columns being proximal to a floor surface on which the ladder is positioned, the first column having a flange positioned in the hollow body of the first column coaxially with the axis of the plurality of columns,
- a plurality of rungs extending between the first stile and the second stile, each rung connected to a column of the first stile and a column of the second stile;
- a first stabilizer housing being connected to the first and second columns, the first stabilizer housing being proximal to the floor surface on which the telescoping ladder is positioned, the first stabilizer housing having a hollow body portion;
- and
- a first stabilizer slidingly connected to the first stabilizer housing, the first stabilizer adapted to move between an extended position and a collapsed position, wherein, in the extended position, the first stabilizer extends out of the hollow body portion of the first stabilizer housing, the first stabilizer extending past the first stile in a direction substantially normal to the axis of the plurality of columns in the extended position, and the first stabilizer adapted to collapse into the hollow body portion of the first stabilizer housing in the collapsed position, the first stabilizer comprising a locking button adapted to protrude past an aperture defined on the first stabilizer housing to lock the first stabilizer in its extended position, wherein, the locking button and the aperture are coaxial to the axis of the plurality of columns in the extended position of the first stabilizer, and
- wherein the flange abuts against the locking button protruding past the aperture of the first stabilizer housing due to the telescoping movement of the plurality of columns in a direction toward the first stabilizer housing, the abutment of the flange against the locking button pushing the locking button away from the aperture and thereby unlocking the first stabilizer from its extended position and into the collapsed position.
