摘要： A traffic barrier comprises a step-like obstruction able to resist or prohibit the advance of a vehicle, a hinged platform disposed in advance of the step-like obstruction and rockable between a lowered position and a raised position, in which its trailing edge is adjacent the top of the step-like obstruction, spring means urging the platform into its raised position, latch means operable to lock the platform in its raised position to permit a vehicle to advance over the step-like obstruction, and control means including a coin-operated device or the like, for controlling the operation of the latch means.In one embodiment, the latch means is normally in its released condition, and is actuated to lock the platform in its raised position when the prescribed parking fee is inserted into coin-operated device. The control means is responsive to advance of the rearmost wheels of the vehicle on to the top of the step-like obstruction to release the latch means and prevent advance of a following vehicle until the coin-operated device is tripped by the driver of the following vehicle.In another embodiment, the latch means is normally retained in its latched condition, and the control means is responsive to the front wheels of a vehicle approaching the platform to release the latch means if the driver of that vehicle does not insert the prescribed parking fee in the coin-operated device.
