  • Patent number: 4919563
    Abstract: A vehicular trafficway or roadway barrier or space barrier for controlling access to the same. The apparatus is installed below the parking space or roadway and includes a retractable barrier which blocks the space being protected when erected and permits access when retracted. The apparatus herein referred to as Scopelock is an entirely self-contained unit which may be operated from normal electrical service or a battery. The entire unit is designed to be unlocked and removed from a casing that is permanently fixed into the ground. Spaceage material protects the unit from moisture. Scopelock can be operated by remote control or coin boxes or keys as desired. Typically, when in place, Scopelock prevents access to vehicular parking spaces while at the same time, capable of providing parking security by limiting the space between Scopelock and other barriers positioned around the vehicles, thereby providing security from theft of the vehicle.
