Anti car-theft device

Abstract

A device for prevention of theft of a vehicle and for keeping a parking space for a vehicle when the vehicle is not parked in the space. The device is a collapsible barrier controlled by a remote control. It has a novel mechanism of protecting accidental damage to cars and to the barrier itself. Protection is afforded by means of a biasing element built into the device which gives way when accidentally hit by an approaching car and then automatically returns to a vertical position. When the vehicle with the remote control approaches and is about to hit the barrier a warning alarm is sounded, or in another embodiment of this invention, the remote sensor in the device is automatically lowered when it senses the approaching vehicle. In another embodiment of this invention the collapsible barrier is secured onto a ceiling above a parking surface enabling a convenient electric source for the devices and easier maintenance and central control over numerous barriers placed in a large parking facility.
