Abstract
A motorized traffic-way controller wherein a retractile tire barrier and opening gate barrier are coordinated to operate in unison by a motor drive that is recycled by closing a mode switch through cam controlled "stop" and "go" switches responsive to the position of the motor drive, the installation being above grade with low profile modules having retractile tooth configurations that projects for tire damage, and with a signal barrier supported by a drive unit at the side of the traffic-way and in the form of an arm that is lifted when the tooth configuration is retracted, the modules and drive unit being adapted to coupled engagement one with the other when assembled.
Claims19
A motorized tire barrier and signal barrier vehicle traffic-way controller, and including:
- at least one elongated grade level tire barrier module extending transversely of the vehicle traffic-way, and comprised of a frame with oppositely ramped margins extending to spaced rail members defining a channel for the accommodation of a shaft rotatable therein and coextensive therewith, and a plurality of spaced blades projecting from one side of the shaft to extend upwardly from and retractile into the channel through rotation of the shaft;
- a signal barrier at one side of the traffic-way, and comprised of a vertically disposed frame with a standard and a head defining a chamber for the accommodation of a shaft rotatable therein, and an arm projecting from the shaft to extend horizontally across the traffic-way and retractile into a vertical position at the side of the traffic-way through rotation of the shaft;
- a drive unit for motorizing the blades and arm between extended "stop" positions and retracted "go" positions, and comprised of a reversible motor drive means with a bellcrank reciprocably operable through an obtuse angular displacement, with a connecting link from a first bellcrank to a lever on the at least one module shaft reciprocably operable through an acute angular displacement, and with a connecting link from a second bellcrank to a lever on the signal arm shaft reciprocably operable through an acute angular displacement;
- and control means for reversibly operating the motor drive means and positioning the tire barrier and signal barrier shafts in said "stop" and "go" positions.
A drive unit for selective motorized adaptation to a tire barrier and a signal barrier of a traffic-way controller:
- wherein the tire barrier comprises at least one elongated grade level tire barrier module extending transversely of the vehicle traffic-way, and comprised of a frame with oppositely ramped margins extending to spaced rail members defining a channel for the accomodation of a shaft rotatable therein and coextensive therewith, and a plurality of spaced blades projecting from one side of the shaft to extend upwardly from and retractile into the channel through rotation of the shaft;
- wherein the signal barrier comprises a vertically disposed frame at one side of the traffic-way and with a standard and a head defining a chamber for the accomodation of a shaft rotatable therein, and an arm projecting from the shaft to extend horizontally across the traffic-way and retractile into a vertical position at one side of the traffic-way through rotation of the shaft;
- the said drive unit being selectively coupled with and to operate the signal barrier arm and the tire barrier blades between extended "stop" positions and retracted "go" positions, and comprised of a reversible motor drive means with a bellcrank reciprocably operable through an obtuse angular displacement, with a connecting link to be coupled from a first bellcrank to a lever on the at least one module shaft reciprocably operable through an acute angular displacement, and with a connecting link to be coupled from a second bellcrank to a lever on the signal arm shaft reciprocably operable through an acute angular displacement;
- and control means for reversibly operating the motor drive means and conditioning the traffic-way controller in said "stop" and "go" positions.
