Abstract
Abstract Traffic control apparatus employs an elongated barrier separating adjacent lanes of a highway. The barrier consists of a series of barrier sections hingedly secured together. A self propelled vehicle engages the barrier sections seriatim, elevates them and guides them within the vehicle along a generally sinusoidal path from one lane divider to another and discharges them.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
191 words
A segmented traffic control barrier capable of providing a safe separation between continuous lanes of opposing vehicle traffic that are adapted to be easily moved across lanes for reversible traffic lanes comprising: a continuous barrier having a plurality of connected barrier sections, each of said sections having a flat base member and a vertical web member fixedly secured to said base member to form an inverted T-like structure, hinge means connecting said barrier sections in a continuous string to form said barrier, said hinge means including a first hinge means located adjacent to the top of said vertical web at each end of each section and a second hinge means located adjacent to the bottom of said vertical web at each end of each section, said first hinge means allowing articulation between the connected sections without internal movement in said hinge means and said second hinge means operable to allow the base portions of adjacent section to move together and apart while maintaining vertical registry between adjacent sections, said hinge means allowing articulation in said barrier when the barrier is relocated from one lane to another through a sinusoidal transposition path.
Claim 2
Dependent Claim
191 words
A segmented traffic control barrier capable of providing a safe separation between continuous lanes of opposing vehicle traffic that are adapted to be easily moved across lanes for reversible traffic lanes comprising: a continuous barrier having a plurality of connected barrier sections, each of said sections having a flat base member and a vertical web member fixedly secured to said base member to form an inverted T-like structure, hinge means connecting said barrier sections in a continuous string to form said barrier, said hinge means including a first hinge means located adjacent to the top of said vertical web at each end of each section and a second hinge means located adjacent to the bottom of said vertical web at each end of each section, said first hinge means allowing articulation between the connected sections without internal movement in said hinge means and said second hinge means operable to allow the base portions of adjacent section to move together and apart while maintaining vertical registry between adjacent sections, said hinge means allowing articulation in said barrier when the barrier is relocated from one lane to another through a sinusoidal transposition path.
Claim 3
Dependent Claim
35 words
The segmented traffic control barrier defined in claim 1 wherein the underside of the base member includes a longitudinal groove along its axial length whereby the barrier may be placed over lane markers for alignment.
Claim 4
Dependent Claim
52 words
The segmented traffic control barrier defined in claim 1 including separate anchor means connected to its opposite ends, said anchor means operable to prevent relative movement of said barrier relative to said anchor means and at least one tensioning means in said anchor means operable to place increased tension on said barrier.
Claim 5
Dependent Claim
46 words
The segmented traffic control barrier as defined in claim 1 wherein the top of the vertical web member includes a horizontal flange by which the barrier may be supported on dolly means when it is being transposed from lane to lane along a sinusoidal transposition path.
