Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
152 words
A ladder having an anchoring system comprising in combination: a ladder including a pair of rails supporting a plurality of parallel spaced apart rungs, said ladder having a lower end to be positioned on the ground with the side rails extending upwardly in a normal position of use of the ladder and a lowermost rung of the ladder in said normal position of use including at least one aperture; and at least one stake adapted to be inserted through said at least one aperture in said lowermost rung including a first portion adapted to be driven into the ground and a second portion adapted to engage an upwardly facing portion associated with the lowermost rung in said normal upwardly extending position of use of the side rails with said first portion driven in the ground for anchoring the lower end of said ladder to the ground against movement in substantially all directions.
Claim 2
Dependent Claim
152 words
A ladder having an anchoring system comprising in combination: a ladder including a pair of rails supporting a plurality of parallel spaced apart rungs, said ladder having a lower end to be positioned on the ground with the side rails extending upwardly in a normal position of use of the ladder and a lowermost rung of the ladder in said normal position of use including at least one aperture; and at least one stake adapted to be inserted through said at least one aperture in said lowermost rung including a first portion adapted to be driven into the ground and a second portion adapted to engage an upwardly facing portion associated with the lowermost rung in said normal upwardly extending position of use of the side rails with said first portion driven in the ground for anchoring the lower end of said ladder to the ground against movement in substantially all directions.
Claim 3
Dependent Claim
27 words
The ladder and anchoring system as defined in claim 1 wherein said stake is generally L-shaped including a lateral offset defining said second portion of the stake.
Claim 4
Dependent Claim
95 words
A ladder having an anchoring system comprising: a ladder including a pair of side rails and two holes, one hole in each of said side rails below a lowermost rung of the ladder in a normal position of use of the ladder; and two stakes, one adapted to be inserted through each of said two holes in said side rails, each stake including a first portion adapted to be driven into the ground and a second portion adapted to engage against a respective side rail at said respective hole in the normal position of use.
Claim 5
Dependent Claim
95 words
A ladder having an anchoring system comprising: a ladder including a pair of side rails and two holes, one hole in each of said side rails below a lowermost rung of the ladder in a normal position of use of the ladder; and two stakes, one adapted to be inserted through each of said two holes in said side rails, each stake including a first portion adapted to be driven into the ground and a second portion adapted to engage against a respective side rail at said respective hole in the normal position of use.
Claim 6
Dependent Claim
69 words
The ladder and anchoring system as defined in claim 3 wherein each of said two holes and each of said stakes are relatively sized such that each stake is receivable through said hole in a direction angularly downwardly and inwardly relative to said side rails in the position of use of the ladder with said second portion of said stake disposed at an external side of the side rail.
Claim 7
Independent Claim
95 words
A method of anchoring a ladder to the ground comprising the steps: positioning a ladder having an aperture in a lowermost rung in a normal upwardly extending position of use; inserting a stake including a portion adapted to be driven into the ground and a portion adapted to engage an upwardly facing portion of the lowermost rung through said aperture; and driving the stake into the ground with said portion adapted to engage said upwardly facing portion against said upwardly facing portion whereby, said ladder is pulled toward said ground and is restrained against movement.
Claim 8
Independent Claim
95 words
A method of anchoring a ladder to the ground comprising the steps: positioning a ladder having an aperture in a lowermost rung in a normal upwardly extending position of use; inserting a stake including a portion adapted to be driven into the ground and a portion adapted to engage an upwardly facing portion of the lowermost rung through said aperture; and driving the stake into the ground with said portion adapted to engage said upwardly facing portion against said upwardly facing portion whereby, said ladder is pulled toward said ground and is restrained against movement.
