Barrier gate for longitudinal highway barrier
First Claim
1. A barrier gate for a longitudinal highway barrier of the type having at least first and second axially aligned barrier segments separated by a gap therebetween, said barrier gate comprising:
- an elongated gate;
means for mounting the gate in alignment with said first barrier segment such that the gate extends toward the second barrier segment along an axis defined by the first barrier segment; and
means for translating the gate along the axis between a first position, in which at least a portion of the gate overlaps the first barrier segment along the axis and reveals at least a portion of the gap, and a second position, in which at least a portion of the gate is positioned in the gap to extend along the axis toward the second barrier segment, thereby closing at least a portion of the gap;
said translating means comprising a motor mounted adjacent one end of the gap, a drive wheel mounted to engage the gate to move the gate axially past the drive wheel, and a drive member interconnecting the motor and the drive wheel.

Abstract
A barrier gate for a longitudinal highway barrier of the type having first and second axially aligned barrier segments separated by a gap includes two elongated gates. These gates are mounted by rails and wheels for axial movement between an opened position in which the gates reveal the gap, and a closed position, in which the gates close the gap. The gates are designed to fit over and straddle the adjacent barrier segments, and are provided with a sidewall configuration that matches the shape of the barrier segments to eliminate snagging surfaces.

6. A barrier gate for a longitudinal highway barrier of the type having at least first and second axially aligned barrier segments separated by a gap therebetween, said barrier gate comprising:
-
first and second elongated gates; means for mounting the first gate in alignment with the first barrier segment such that the first gate extends toward the second barrier segment along an axis defined by the first barrier segment; means for mounting the second gate in alignment with the second barrier segment such that the second gate extends toward the first barrier segment along the axis; means for translating the first and second gates along the axis between a first position, in which at least a portion of the first and second gates overlap the first and second barrier segments, respectively, along the axis to reveal at least a portion of the gap, and a second position, in which at least portions of the first and second gates are positioned in the gap to extend toward one another along the axis, thereby closing at least a portion of the gap; said translating means comprising two motors, each mounted adjacent a respective end of the gap, two drive wheels, each mounted to engage the respective gate to move the respective gate axially past the respective drive wheel, and two drive members, each interconnecting the respective motor and drive wheel. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A barrier gate for a longitudinal highway barrier of the type having at least first and second axially aligned barrier segments separated by a gap therebetween, said barrier gate comprising:
-
first and second elongated gates; a telescoping mounting arrangement operative to mount the first gate in alignment with the first barrier segment such that the first gate is movable along an axis defined by the first barrier segment; a telescoping mounting arrangement operative to mount the second gate in alignment with the second barrier segment such that the second gate is movable along an axis defined by the second barrier segment; a drive mechanism coupled to the first and second gates to translate the first and second gates between a first position, in which at least portions of the first and second gates axially overlap the first and second barrier segments, respectively, to reveal at least a portion of the gap, and a second position, in which at least portions of the first and second gates are positioned in the gap to extend toward one another, thereby closing the gap; said drive mechanism comprising two motors, each mounted adjacent a respective end of the gap, two drive wheels, each mounted to engage the respective gate to move the respective gate axially past the respective drive wheel, and two drive members, each interconnecting the respective motor and drive wheel. - View Dependent Claims (15, 16, 17, 18)
