Abstract

Abstract A post designed for sign post or guide marker use that will yield on impact and that will resume substantially its original configuration after the impact force has been removed. The post is formed as a single member, but with formed longitudinal shear planes to allow it to split along such shear planes upon impact, thereby reducing the tendency of the post to shear transversely. Correspondingly shaped caps and restrainers may be used during placement of the posts and to insure cohesiveness after shearing has occurred.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 68 words
A roadway delineator comprising an elongate post made of elastic materials and having at least one longitudinal shear plane extending substantially the length of the post, and individual components separated by each said longitudinal shear plane; a collar surrounding the post at one end thereof; a highway marker sign affixed to the collar; and means affixing the collar to only one of the individual components of the post.
Claim 2
Dependent Claim 68 words
A roadway delineator comprising an elongate post made of elastic materials and having at least one longitudinal shear plane extending substantially the length of the post, and individual components separated by each said longitudinal shear plane; a collar surrounding the post at one end thereof; a highway marker sign affixed to the collar; and means affixing the collar to only one of the individual components of the post.
Claim 3
Dependent Claim 103 words
A roadway delineator comprising an elongate post made of elastic materials and having at least one longitudinal shear plane extending substantially the length of the post, and individual components separated by each said longitudinal shear plane; a pointed tip telescoped onto one end of the post; at least one collar closely fitting around and slidable on the post; a cap having a flat, impact receiving upper surface and a lower recess closely fitting over the other end of the post; a highway marker sign affixed to the collar; and means fixing the collar to only one of the individual components of the post.
Claim 4
Dependent Claim 103 words
A roadway delineator comprising an elongate post made of elastic materials and having at least one longitudinal shear plane extending substantially the length of the post, and individual components separated by each said longitudinal shear plane; a pointed tip telescoped onto one end of the post; at least one collar closely fitting around and slidable on the post; a cap having a flat, impact receiving upper surface and a lower recess closely fitting over the other end of the post; a highway marker sign affixed to the collar; and means fixing the collar to only one of the individual components of the post.
Claim 5
Dependent Claim 57 words
A roadway delineator comprising an elongate post made of elastic materials and having at least one longitudinal shear plane extending substantially the length of the post, each said shear plane being at least partially formed by a reduction in thickness of the post material at such plane, and individual components separated by each such longitudinal shear plane.
Claim 6
Dependent Claim 57 words
A roadway delineator comprising an elongate post made of elastic materials and having at least one longitudinal shear plane extending substantially the length of the post, each said shear plane being at least partially formed by a reduction in thickness of the post material at such plane, and individual components separated by each such longitudinal shear plane.
Claim 7
Dependent Claim 34 words
The roadway delineator of claim 3, further including at least one collar extending at least partially around and slidable on said post, whereby said collar holds said individual components in a bundled together relationship.
Claim 8
Dependent Claim 62 words
A roadway delineator comprising an elongate post made of elastic materials and having at least one longitudinal shear plane extending substantially the length of the post, each said shear plane is at least partially formed by using fibers of lower tensile strength in said planes than are used elsewhere in the delineator, and individual components separated by each such longitudinal shear plane.
Claim 9
Dependent Claim 62 words
A roadway delineator comprising an elongate post made of elastic materials and having at least one longitudinal shear plane extending substantially the length of the post, each said shear plane is at least partially formed by using fibers of lower tensile strength in said planes than are used elsewhere in the delineator, and individual components separated by each such longitudinal shear plane.
Claim 10
Dependent Claim 34 words
The roadway delineator of claim 5 further including at least one collar extending at least partially around and slidable on said post, whereby said collar holds said individual components in a bundled together relationship.
Claim 11
Dependent Claim 65 words
A roadway delineator comprising an elongate post made of elastic materials and having at least one longitudinal shear plane extending substantially the length of the post, each said shear plane is at least partially formed by providing a reinforcement layer including transversely extending fibers on areas of the delineator other than each said shear plane and individual components separated by each such longitudinal shear plane.
Claim 12
Dependent Claim 65 words
A roadway delineator comprising an elongate post made of elastic materials and having at least one longitudinal shear plane extending substantially the length of the post, each said shear plane is at least partially formed by providing a reinforcement layer including transversely extending fibers on areas of the delineator other than each said shear plane and individual components separated by each such longitudinal shear plane.
Claim 13
Dependent Claim 34 words
The roadway delineator of claim 7, further including at least one collar extending at least partially around and slidable on said post, whereby said collar holds said individual components in a bundled together relationship.
