Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
A ladder support structure, comprising: (a) a base having a pyramidal configuration, said base including two pairs of legs converging upwardly to a common junction at an apex of the pyramidal configuration; (b) a ladder rest for supporting a ladder extending transverse to said legs and being rigidly fixed to said base at the apex of the pyramidal configuration, said rest extending for a predetermined distance on opposite side of said apex, the transverse extension of said rest having a length which is less than but which approximately equals the corresponding dimension of the base distal to said apex; and (c) ladder stops affixed to opposite ends of the ladder rest and extending substantially perpendicular thereto for preventing sliding movement of a ladder on the ladder rest.
Claim 2
Dependent Claim
127 words
A ladder support structure, comprising: (a) a base having a pyramidal configuration, said base including two pairs of legs converging upwardly to a common junction at an apex of the pyramidal configuration; (b) a ladder rest for supporting a ladder extending transverse to said legs and being rigidly fixed to said base at the apex of the pyramidal configuration, said rest extending for a predetermined distance on opposite side of said apex, the transverse extension of said rest having a length which is less than but which approximately equals the corresponding dimension of the base distal to said apex; and (c) ladder stops affixed to opposite ends of the ladder rest and extending substantially perpendicular thereto for preventing sliding movement of a ladder on the ladder rest.
Claim 3
Dependent Claim
34 words
A ladder support structure as recited in claim 1 wherein said base includes a first pair of legs of a first predetermined length and a second pair of legs of a second predetermined length.
Claim 4
Dependent Claim
29 words
A ladder support structure as recited in claim 2 wherein the length of said first pair of legs is dissimilar from the length of said second pair of legs.
Claim 5
Dependent Claim
29 words
A ladder support structure as recited in claim 3 wherein said first pair of legs has a length which is longer than that of said second pair of legs.
Claim 6
Dependent Claim
31 words
A ladder support as recited in claim 3 wherein said first pair of legs define a geometric plane, said ladder stops extending away from said ladder rest in said first plane.
Claim 7
Dependent Claim
36 words
A ladder support as recited in claim 1 further including spacers adjacent the ladder stops for inhibiting slippage of a ladder into the ladder stops to establish a spacing between the ladder and the ladder stops.
Claim 8
Dependent Claim
38 words
A ladder support as recited in claim 6 wherein the stop spacers extend upwardly from the ladder rest for approximately one half inch and the ladder stops extend upwardly from the ladder rest for at least two inches.
