Abstract
A ladder having pivotable folding riser sections, includes at least one pair of elongated riser components connected by a folding joint. The components have mating contacting ends abutting each other at an angle 45.degree. from the linear axis of the components. A reinforcing member concentric with said components is positioned across the joint, and a pivotable connection is formed by hinge members connected to each of the ladder components which are pivotally connected to each other by means of a hinge pin located exteriorally of the components. The invention also provides pivoting stand off members and a strap tightening mechanism for providing tightening tension equally on both ends of the strap which thus is not caused to move laterally during tightening.
Claims7
In a ladder having risers formed of pivotable folding riser sections, a pair of elongated hollow tubular riser components forming said sections and connected by a folding joint, said components having mating contacting ends abutting each other at an obtuse angle relative to the linear axis of said components,
- a pivotable connection formed by a pair of hinge members, said hinge members each being connected to one of said riser components and pivotally connected to each other by means of a hinge pin located exteriorly of said components, said hinge members together concentrically circumscribing said folding joint between said hollow tubular riser components, and
- a reinforcing member concentric with and axially movable along said riser components, said reinforcing member being slidable away from said joint to allow folding of said joint and serving to prevent folding of said joint when positioned across said joint.
