VEHICLE HAVING VEHICLE-MOUNTED DUAL RETRACTABLE TELESCOPING STRUCTURES HOUSING SURVEILLANCE EQUIPMENT WITH ONE STRUCTURE BEING MOUNTED TO FLATBED OF THE VEHICLE AND ANOTHER STRUCTURE BEING FULLY RETRACTABLE WITHIN VEHICLE

A surveillance equipment platform mounting in an interior cabin of a vehicle. The interior cabin of the vehicle has a roof with an opening. The surveillance equipment platform includes a retractable telescoping structure having surveillance equipment mounted so as to extend through the opening of the roof, and to fully retract into the interior cabin. The surveillance equipment platform also includes a sealing device that mounts to the retractable telescoping structure below the surveillance equipment and oriented parallel to the roof of the interior cabin. The sealing device includes an elastically deformable gasket that elastically deforms during travel of the sealing device through the roof of the interior cabin when the surveillance equipment extends through the opening in the roof during extension of the retractable telescoping structure, and when the surveillance equipment retracts into the interior cabin during retraction of the retractable telescoping structure.
