Ladder securing apparatuses, ladders incorporating same and related methods
View Patent ↗A ladder is provided comprising a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. A pair of hooks are located such that each hook is positioned adjacent and upper end of an associated rail. A securing apparatus is coupled adjacent the upper end of the first pair of spaced apart rails. The securing apparatus includes a pair of spaced apart engaging members and may include a cross-member coupled therebetween. Each of the engagement members is pivotal with respect to an associated rail of the first pair of spaced apart rails. In one embodiment, the securing apparatus lacks any biasing members (e.g., springs or actuators) or locking members. The engagement members and hooks cooperatively encircle and overhead, generally horizontal support member to support and secure the ladder in a desired position.
1. A ladder comprising:
a first pair of spaced apart rails;
a plurality of rungs extending between and coupled to the first pair of spaced apart rails;
a first hook positioned adjacent an upper end of a first rail of the first pair of spaced apart rails;
a second hook positioned adjacent an upper end of a second rail of the first pair of spaced apart rails;
a securing apparatus comprising a first engagement member positioned adjacent the first hook and a second engagement member positioned adjacent the second hook, wherein the first hook is positioned on a first side of the first rail and the first engagement member is positioned on a second, opposing side of the first rail, and wherein the second hook is positioned on a first side of the second rail and the second engagement member is positioned on a second, opposing side of the second rail, wherein the securing apparatus is configured to engage an overhead, horizontal support member, such that:
upon application of force to a portion of the first engagement member by the overhead, horizontal support member the first engagement member is displaced from a first position to a second position relative to the first rail such that the first hook and the first engagement member cooperatively encircle and grip a first portion of the overhead, horizontal support member, the first hook and the first engagement member each being in contact with the overhead, horizontal support member when the first engagement member is in the second position; and
upon application of force to a portion of the second engagement member by the overhead, horizontal support member the second engagement member is displaced from a first position to a second position relative to the second rail such that the second hook and the second engagement member cooperatively encircle and grip a second portion of the overhead, horizontal support member, the second hook and the second engagement member each being in contact with the overhead, horizontal support member when the second engagement member is in said second position.
2. The ladder of claim 1 , further comprising a second pair of rails and another plurality of rungs extending between and coupled to the second pair of spaced apart rails, wherein the second pair of rails are slidably coupled with the first pair of rails.
3. The ladder of claim 1 , further comprising a safety apparatus having a safety line and an attachment mechanism coupled therewith.
4. The ladder of claim 3 , wherein the safety line is coupled with an inertia locking mechanism.
5. The ladder of claim 1 , further comprising a second securing apparatus, the second securing apparatus including a first arm, a second arm, and a strap member coupled between the first arm and the second arm, wherein the first arm is pivotal relative to the first rail of the ladder and the second arm is pivotal relative to the second rail of the ladder.
6. The ladder of claim 5 , wherein the second securing apparatus includes a first ratcheting mechanism associated with the first arm and a second ratcheting mechanism associated with the second arm.
7. The ladder of claim 6 , wherein the first and second ratcheting mechanisms are configured to permit rotation of the first and second arms towards one another, but selectively prohibit rotation of the first and second arms away from one another.
