THEFT-DETERRENT SYSTEM FOR CONTAINER VEHICLE

Abstract

A theft-deterrent assembly for a container vehicle includes a physical barrier that is movable between a closed position that prevents the opening of a discharge port for the product carried in the container, and an open position that allows the opening of the discharge port. A sensor is provided that determines if the physical barrier is in the open position or in the closed position. The sensor is operatively attached to a theft-deterrent controller that is adapted to record the movement of the physical barrier between the open and closed positions upon the occurrence of such movement.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

[0019] This description of preferred embodiments of the invention is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description of this invention. The drawing figures are not necessarily to scale, and certain features of the invention may be shown exaggerated in scale or in somewhat schematic form in the interest of clarity and conciseness.

[0020] As shown in FIG. 1, container trailer assembly 10 includes container 12, which is divided into four fluid product compartments (not shown). Discharge ports 14, 16, 18 and 20 are provided in discharge port bank 22 that is located below container 12. Each of the discharge ports is operatively connected to and in fluid communication with one of the fluid product compartments.

[0021] The preferred double-bar interlock assembly is attached to frame component 23 of container trailer assembly 10. This double-bar interlock assembly includes actuation bar 24 that is operatively connected to blocking bar 26. Blocking bar 26 is attached to frame component 23 by a pair of hinges, one of which, hinge 27, is shown in FIGS. 2 and 3. This double-bar interlock assembly is configured so that when actuation bar 24 is moved by an operator of the container vehicle from the actuation bar closed position shown in FIG. 2 to the actuation bar open position shown in FIG. 3, blocking bar 26 will pivot on its hinges about substantially horizontal pivot axis PH to move from the blocking bar closed position, in which it prohibits or blocks access to the discharge ports, to the blocking bar open position which allows access to the discharge ports. This preferred blocking bar physically interferes with the discharge valves of the discharge ports when in the blocking bar closed position. In another embodiment of the invention (not shown), the blocking bar may be pivotally attached at a first end so as to pivot about a substantially vertical pivot axis on a first side of the discharge port bank between an open position that allows access to the discharge ports and a closed position that engages a latch component on the second end of the blocking bar with a latch assembly on the second side of the discharge port bank so as to physically interfere with the discharge valves of the discharge ports. In yet another embodiment of the invention (also not shown), the blocking bar may operate to close valves in the discharge ports when in the closed position.

[0022] To the left of discharge port bank 22 (as viewed in FIG. 1) is proximity sensor enclosure 28 which encloses proximity sensor 30 (shown in FIG. 4). Also shown in FIG. 1 is controls enclosure 32, which encloses the controls for operating the discharge ports and other features of trailer assembly 10, and also includes theft-deterrent controller 34. The theft-deterrent controller may include a processor, a memory component and other components for running an application, for communicating with a global positioning system and for transmitting a signal to a third party that is remote from the container vehicle. Various circuits, including but not limited to power supply circuitry, may also be associated with and operatively connected to the theft-deterrent controller. Numerous commercially available microprocessors can be configured to perform the functions of the theft-deterrent controller. It should be appreciated that the theft-deterrent controller could readily be embodied in a general purpose computer or machine microprocessor capable of controlling numerous functions of trailer assembly 10.

[0023] When actuation bar 24 is moved to the actuation bar open position (i.e., upwardly, as shown in the drawings), blocking bar 26 will also move to the blocking bar open position. This sets normally-open proximity sensor 30 to an open state, which causes theft-deterrent controller 34 to record the time, and preferably the location of the container vehicle (using access to a global positioning system). In a preferred embodiment of the invention, theft-deterrent controller 34 will also cause an “open” signal to be sent to a third party that is remote from the container vehicle. Then, when the actuation bar 24 is moved to the actuation bar closed position shown in FIGS. 1 and 2, blocking bar 26 will also move to the blocking bar closed position. This sets proximity sensor 30 to a closed state, which causes theft-deterrent controller 34 to record the time, and preferably the location of the container vehicle. In a preferred embodiment of the invention, theft-deterrent controller 34 will also cause a “closed” signal to be sent to a third party that is remote from the container vehicle. The “open” and “closed” status information may also be stored in the memory component of theft-deterrent controller 34 for retrieval at the container vehicle terminal or other location.

[0024] Because the proximity sensor is not accessible to the vehicle operator (i.e., it is enclosed in tamper-proof sensor enclosure 28), it is impossible for a vehicle operator or other person to override or tamper with the theft-deterrent system without cause obvious damage to trailer assembly 10. The invention thus provides a relatively simple system and assembly for detecting in real time and recording when a discharge port is accessed. Furthermore, in a preferred embodiment of the invention, the system automatically communicates with a fleet management system or other party remote from the container vehicle to notify such party that a discharge port has been accessed.

[0025] Although this description contains many specifics, these should not be construed as limiting the scope of the invention but as merely providing illustrations of the presently preferred embodiment thereof, as well as the best mode contemplated by the inventors of carrying out the invention. The invention, as described and claimed herein, is susceptible to various modifications and adaptations, as would be understood by those having ordinary skill in the art to which the invention relates.
