Abstract

Abstract A picket fence comprising a plurality of parallel and laterally spaced metal pickets which are interconnected by a plurality of parallel pairs of stringers. The stringers are made from a metal material and have opposite ends shaped in a tubular configuration which are received in mating recesses on adjacent, parallel pickets such that the pickets are rotatable about the tubular configurations of the stringers whereby the pickets and their associated stringers are movable with respect to each other in such a manner that the pickets may be disposed along a curved path.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 168 words
A flexible picket fence comprising: a plurality of parallel, laterally spaced pickets; and a plurality of parallel pairs of stringers interconnecting said pickets, each stringer having opposite ends pivotally attached to adjacent, laterally spaced pickets such that said pickets and their associated stringers are movable with respect to each other about an axis parallel to the longitudinal axis of said pickets while maintaining said pickets in said parallel relationship and permitting said pickets to be disposed along a curved path, each of said pickets having a front wall and side walls connected thereto, each side wall having longitudinally spaced connecting joints, each of said connecting joints having a slot dividing the joint into upper and lower recesses including circular rings adjacent to said slot between said slot and the upper and lower recesses, said recesses having a circular configuration, each of said stringers having tubular end sections, said tubular end sections being matingly received by said picket recesses to permit pivotal movement between said pickets and said stringers.
Claim 2
Dependent Claim 168 words
A flexible picket fence comprising: a plurality of parallel, laterally spaced pickets; and a plurality of parallel pairs of stringers interconnecting said pickets, each stringer having opposite ends pivotally attached to adjacent, laterally spaced pickets such that said pickets and their associated stringers are movable with respect to each other about an axis parallel to the longitudinal axis of said pickets while maintaining said pickets in said parallel relationship and permitting said pickets to be disposed along a curved path, each of said pickets having a front wall and side walls connected thereto, each side wall having longitudinally spaced connecting joints, each of said connecting joints having a slot dividing the joint into upper and lower recesses including circular rings adjacent to said slot between said slot and the upper and lower recesses, said recesses having a circular configuration, each of said stringers having tubular end sections, said tubular end sections being matingly received by said picket recesses to permit pivotal movement between said pickets and said stringers.
Claim 3
Dependent Claim 44 words
The flexible picket fence defined in claim 1 further comprising: a plurality of stake members; means for connecting said stake members to selected numbers of said pickets at the base thereof for permitting said selected number of pickets to be affixed to the ground.
Claim 4
Dependent Claim 19 words
The flexible picket fence defined in claim 1 wherein each of said stringers is fabricated from a metal material.
Claim 5
Dependent Claim 19 words
