## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This patent application is a continuation of U.S. Utility Application No. 60/784,178, filed on Jun. 2, 2006, entitled “Window Insert for Vehicles,” the disclosure of which is incorporated as if fully written herein.


BACKGROUND OF THE INVENTION
The present invention relates in general to ventilation devices that are inserted into or otherwise installed in or used with windows, and more specifically to an adaptable, ventilating insert for use with the windows of trucks, tractor-trailer rigs and the like.
Truck drivers often rest or sleep in the cabs of their vehicles. To avoid running the vehicle's engine to power an air-conditioner unit, the driver may wish to open at least one of the vehicle's windows to provide ventilation to the interior of the cab. An open window, however, may create as many problems as it solves because insects, the elements, thieves, and other intruders can access the interior of the cab. Thus, there is a need for a system and/or device that allows the operator of a truck or similar vehicle to ventilate the interior of the vehicle's cab without compromising privacy, security, and safety. Such a system or device would also prevent unwanted insects and birds from entering the ventilated cab and would allow the operator of a truck to rest or sleep in the vehicle's cab more peacefully and comfortably than a partially or completely open window would permit.

Accordingly, the following embodiments of the invention are set forth without any loss of generality to, and without imposing limitations upon, the claimed invention.
The present invention relates to ventilating systems and devices for use with vehicle windows, and particularly those windows without vent posts. A first embodiment of this invention provides a ventilation system for use with vehicle windows. This system includes a frame mountable within the opening of a vehicle window; an insert mountable within the frame; and an adapter. The adapter is attachable to the frame and further includes a plurality of score lines formed therein for facilitating changing the dimensions of the adapter, if necessary. A second embodiment of this invention provides a device for use with vehicle windows. This device includes a frame having an aperture formed therein. The frame further includes a substantially linear top edge; a substantially linear bottom edge having a plurality of mounting flanges formed thereon; a rear panel that further includes a top extension and a bottom extension; and a front panel that further includes a plurality of score lines formed therein for facilitating changing the dimensions of the front panel, if necessary. This device also includes an insert mountable within the aperture formed in the frame; and an adapter. The adapter is attachable to the frame and further includes a plurality of score lines formed therein, which facilitate changing the dimensions of the adapter, if necessary. A third embodiment of this invention provides a method for ventilating the interior of a vehicle, comprising the steps of lowering a vehicle window to a predetermined height; placing a device in the window, wherein the device further comprises: a frame; an ventilating insert mountable within the frame; and an adapter that is attachable to the frame and that further includes a plurality of score lines formed therein for facilitate changing the dimensions of the adapter; raising the window to a height appropriate for securing the device in the window; and adjusting the position of the adapter to fill a portion of the window not filled by the frame.
With reference now to the Figures, FIG. 1 provides a side-view of an exemplary embodiment of the ventilation system of the present invention. In this view, window insert 10 is oriented for insertion into the passenger side of a vehicle, thus the “rear” portion of window insert 10 appears on the left side of the Figure and the “front” portion of window insert 10 appears on the right side of the figure. In this embodiment, window insert 10 includes a frame portion 20 and an attachable adapter 50, which allows window insert 10 to be used with a variety of window sizes and vehicle types. When properly installed in a window opening, this embodiment of window insert 10 provides ventilation through a screened portion while simultaneously blocking-off the non-ventilated portions of the window opening.
As best shown in FIGS. 1-2, frame 20 is substantially rectangular in shape and includes a rectangular aperture 21, which is adapted to receive an insert that typically includes screen frame 22, screen material 23, and screen supports 24. Screen supports 24 cooperate with one another to form a lattice-like structure for supporting screen material 23. As described in U.S. Pat. No. 4,913,212, the entirety of which is incorporated by reference herein, a mesh screen may be used to cover screen frame 22 and screen supports 24. In other embodiments of the present invention, the screen supports 24 are covered with a substantially impermeable, solid material and at least one aperture, opening, or vent is formed in a portion of window insert 10. In still other embodiments, the entire operative surface of window insert 10 is solid and substantially impermeable, and at least one aperture or vent is formed in a portion of the surface of window insert 10. A ventilating hose, tube, or other device may then be attached to this at least one aperture or vent for the purpose of providing outside air to the interior of the vehicle.
Again with reference to FIGS. 1-2, frame 20 includes a substantially linear top edge and a substantially linear bottom edge. A plurality of substantially rectangular mounting flanges 25, which are offset, front to back, left to right, from one another along the length of the bottom edge (see FIGS. 1-2), are included for the purpose of engaging the top edge of a window and stabilizing window insert 10 when the device is properly installed. A rear panel 36 is formed integrally with frame 20 and includes a removable top extension 38 and a bottom extension 40. Bottom extension 40 further includes a plurality of ridges 41, which provides additional strength and stability to bottom extension 40. Both top extension 38 and bottom extension 40 assist in stabilizing window insert 10 within the frame of a vehicle's door when window insert 10 is properly installed.
As shown in FIGS. 1-2, the front portion of frame 20 also includes a front panel having an integral adapter 26, which permits window insert 10 to be used with a variety of different vehicles having different window opening geometries. Integral adapter 26 further includes a plurality of score lines 28, as well as a plurality of mounting devices, i.e., first pin 30, hook 32, and second pin 34, formed on the lower portion thereof. These mounting devices are formed on both sides of frame 20 so that window insert 10 may re-oriented and used on either the driver or passenger side of the vehicle. The mounting devices cooperate with a plurality of corresponding mounting apertures, i.e., first mounting aperture 54, second mounting aperture 56, and third mounting aperture 58, to attach adaptor 50 to frame 20. A plurality of ribs 27 is formed in integral adapter 26 for adding strength and stability for this portion of window insert 10. Score lines 28 allow a user of window insert 10 to more easily remove a portion of integral adapter 26 so that frame 20 fits properly into the window opening of a particular vehicle such as, for example, a Kenworth, Peterbilt, Western Star, International, or Mack truck.
As shown in the Figures, an attachable adapter 50 is provided to further accommodate different window opening geometries and to allow the user of window insert 10 to substantially or completely block the portion of an open window that is not ventilated by screen material 23. Attachable adapter 50 also includes a plurality of score lines 52, as well as a first aperture 54, a second aperture 56, and a third aperture 58. Score lines 52 allow the user of window insert 10 to more easily remove a portion of attachable adapter 50 so that the entire window insert 10 fits properly into the window opening of a particular vehicle (see FIG. 3), such as, for example, a Kenworth, Peterbilt, Western Star, International, or Mack truck. The score lines formed in attachable adapter 50 correspond to the score lines formed in integral adapter 26 when the two components are connected to one another. Attachable adapter 50 is connected to integral adapter 26 by placing apertures 54, 56, and 58 over first pin 30, hook 32, and second pin 32 respectively and pressing down to snap attachable adapter 50 into place. For purposes of packaging and storage, attachable adapted 50 may be inverted such that it sits atop integral adapter 26, while still being attached to hook 32. For this purpose, hook 32 also acts as a “hinge” about which attachable adapter 50 may rotate.
The various components of the present invention are typically manufactured from high-impact plastic and/or other acceptable materials according to known manufacturing and fabrication methods and techniques including, but not limited to, injection molding and die cutting. Window insert 10 is typically installed and used to ventilate the interior of a vehicle by trimming both the integral adapter 26 and the attachable adapter 50 to the appropriate size (based on vehicle type); attaching adapter 50 to frame 20 and swinging adapter 50 upward; placing the assembled window insert 10 into the opening between the glass of the window and the door frame; raising the window to engage mounting flanges 25; swinging adapter 50 forward and downward into the bottom of the window opening to block off any space remaining between window insert 10 and the door frame (see FIG. 3). Use of window device 10 may reduce engine wear, save fuel and reduce pollution.
While the present invention has been illustrated by the description of exemplary embodiments thereof, and while the embodiments have been described in certain detail, it is not the intention of the Applicant to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention in its broader aspects is not limited to any of the specific details, representative devices and methods, and/or illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the applicant's general inventive concept.
