Pneumatic door opening and security system

Abstract

A pneumatic door system and a method of using the same are disclosed herein. According to one embodiment, a trailer may include a seamless main door and at least one side door. The doors may be configured to be locked shut with a system of pneumatic locks. The main door may be configured to open and close as controlled by pneumatic pressure applied to a door cylinder. The pneumatic system may be configured to be controlled by an interior control box. The pneumatic system may be configured to operate off of pneumatic pressure in an auxiliary air tank, the pressure being protected by a series of one-way check valves. The pneumatic system may also be configured to operate wirelessly using RFID or Bluetooth technology, among other things, to secure the cargo and facilitate ingress and egress to the trailer.

1 - 9 . (canceled) 
     
     
         10 . A method of operating a pneumatic door system, the method comprising:
 receiving a wireless signal for opening an overhead door positioned on a delivery vehicle;   actuating a pneumatic mechanism to open the overhead door;   determining that it is time to close the overhead door; and   actuating the pneumatic mechanism to close the overhead door.   
     
     
         11 . The method of  claim 10 , wherein the wireless signal is an RFID signal. 
     
     
         12 . The method of  claim 10 , wherein the wireless signal is a Bluetooth signal. 
     
     
         13 . The method of  claim 10 , wherein determining that it is time to close the overhead door comprises determining that the wireless signal is no longer being received. 
     
     
         14 . The method of  claim 10 , wherein determining that it is time to close the overhead door comprises determining that a set time period has expired. 
     
     
         15 . The method of  claim 10 , wherein determining that it is time to close the overhead door comprises a wireless receiver being turned off. 
     
     
         16 . A method of operating a pneumatic door system that includes a controller configured for receiving wireless signals, the method comprising:
 activating a wireless transmitter to transmit a signal to the controller for opening an overhead door positioned on a delivery vehicle; and closing the overhead door by one of a) carrying the wireless transmitter out of range of the controller, or b) causing the wireless transmitter to stop transmitting the signal.   
     
     
         17 . The method of  claim 16 , wherein the signal is a pulsed signal. 
     
     
         18 . The method of  claim 16 , wherein the transmitter continues sending the signal until a user pushes a button. 
     
     
         19 . The method of  claim 16 , wherein the transmitter continues sending the signal until a set time period has elapsed since the transmitter was first activated.
