ABSTRACT:
A parking space barrier comprises a stationary base for anchoring to the ground of a parking space and a moveable pylon attached to the base member by an extensible cable. The pylon comprises a cushioned peripheral portion upstanding from a carriage containing a spring motor attached to one end of the cable. A wirelessly operated lock remotely controlled by the car driver secures the carriage to the base adjacent the entrance to the parking space. A car entering the parking space engages the cushioned peripheral portion and pushes the pylon before it across the parking space to a vehicle admitting position, the cable extending under the car and winding the spring motor so that the pylon will be drawn back by the spring motor and cable with the car when reversing out of the parking space. A manually operable arresting device is provided to maintain the pylon in the vehicle admitting position remote from the base member, if required. An indicator showing the condition of the locking device is mounted at the top of the pylon and directly linked to the locking mechanism to show the locking position.
