Description:
BACKGROUND OF THE INVENTION 
       [0001]    This invention relates to windows for vehicles. More particularly the present invention relates to windows having a panel that can open to enable someone in the truck to deliver packages through the opening created by the open panel. 
         [0002]    Mail delivery personnel generally drive vehicles to deliver mail. These vehicles have vehicle windows that are somewhat standard in size. The windows are much larger then normally needed to deliver the average consumer&#39;s mail. When this occurs in the winter, with cold temperatures, the mail delivery personnel have to open or descend the window to deliver the mail. This large, open area created by the open window causes the personnel to become cold, the heat from within the passenger cabin to escape, inclement weather to enter the passenger cabin of the vehicle, and the personnel to suffer from cold temperatures. 
         [0003]    U.S. Pat. No. 4,932,454 discloses a window insert that is used to reduce the size of the opening needed to deliver mail. The &#39;454 patent discloses a window insert that is secured by the upward force of the top edge of a moveable window  16  engaged with a panel edge  18  of the insert. Thus the insert is disposed between the window and the door frame. This does not allow the window to be closed when the insert is being used or between periods of times of use. 
         [0004]    As can be seen, there is a need for a structure that can reduce the size of an opening required to deliver mail, and yet still allow personnel to close the window, and lock the door for security reasons. There is also a need to carry and store the vehicle window. 
       SUMMARY OF THE INVENTION 
       [0005]    One aspect of the present invention is a vehicle window, comprising: a primary portion; a panel at least partially disposed on said primary portion, said panel is capable of being opened to define an arm opening, said arm opening is capable of receiving an arm and hand of a person therethrough, whereby the vehicle window is capable of being secured to a vehicle door having an original equipment manufacturer&#39;s window, and the original equipment manufacturer&#39;s window may be closed while the vehicle window is installed on the vehicle door. Another aspect is a vehicle window, comprising: a primary portion capable of being removably secured to a door of a vehicle; an openable panel disposed on said primary portion; wherein an original equipment manufacturer&#39;s window may be in a closed position when said primary portion is secured to the door of a vehicle. 
         [0006]    These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
