## Title
Snap-on chrome plated automotive grille overlay

## Abstract

A snap-on automotive grille overlay (10) that is formed with a thin-walled overlay body (20) configured to duplicate an existing automotive grille when nested thereupon. The overlay body (20) includes an essentially rectangular peripheral border (22) that incorporates a rim (24) extending inward from the border periphery. One or more horizontal slats (28) and vertical bars (26) are formed within the border rim to form an ornamental design that mates with a vehicle existing grille. A plurality of inward-protruding clips (32) are integrally formed within the slats and bars for connecting the grille to the vehicle. The clips are beveled (34) on an interior surface (36) and yield sufficiently to permit deflection over a vehicle grille, thus allowing the grille overlay to be snapped into place.

DISCLOSURE OF THE INVENTION
Historically, automobile grilles that cover and admit air to flow into radiators have been made of metal and chrome plated to provide corrosion protection. More recently, vehicle grilles have been made of injection molded thermoplastic with some being plated and others painted. Lately the trend has been to paint a grille, which blends the grille's appearance with the balance of the vehicle, but traditionalists still appreciate the rich and substantial look of a chrome plated grille. Therefore the primary object of the invention is to supply a grille overlay that has the configuration of an original equipment manufacturer grille and simply snaps into place securely over the existing grille, thus duplicating the appearance of a chrome grille without the necessity of removing the existing grille.
An important object of the invention is the easy installation of the grille overlay, as no tools are required and the person attaching the snap-on grille overlay simply places it over the existing vehicle grille until it snaps firmly in place with no further fastening required.
Another object of the invention is that the snap-on grille overlay is thin and replicates the existing grille so completely that it is not apparent to the casual observer that an overlay has been added.
Still another object of the invention is that the snap-on grille overlay is easily produced and, with respect to economies of numbers, the initial cost is reasonable and within the reach of all consumers.
Yet another object of the invention is that the snap-on grille overlay may be removed at a later date without affecting the existing grille in any way.
These and other objects and advantages of the present invention will become apparent from the subsequent detailed description of the preferred embodiment and the appended claims taken in conjunction with the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION
The best mode for carrying out the invention is presented in terms of a preferred embodiment for a snap-on chrome plated automotive grille overlay 10. As shown in FIGS. 1 through 10, the grille overlay 10 is comprised of a thin-walled grille overlay body 20 that is configured to exactly duplicate an existing automotive grille when nested thereupon. The overlay body 20 consists of an essentially rectangular peripheral border 22 that includes a rim 24 that extends inward from the border 22, as best shown in FIGS. 6 and 7.
Most existing automotive grilles incorporate a plurality of vertical bars that are disposed perpendicularly within a border rim, and in many cases the body also includes at least one horizontal slat disposed within the same border rim, thereby forming essentially rectangular openings. The existing automotive grilles are configured in many shapes and designs and are differ from other manufacturers as well as individual models within the same line change sometimes insignificantly and other times substantially for each vehicle particularly in a new model year.
Examples of the grille overlays 10 are shown in FIGS. 1, 2, 6 and 7, with FIGS. 1 and 2 showing a combined horizontal slat 28 and an opposed pair of vertical bars 26. FIGS. 6 and 7 show the rim 24, and a plurality of vertical bars 26 that form rectangular openings 30. It should be noted that the configuration of the overlay body 20 is not limited to the examples shown as there are as many types and styles as there are different vehicles. Some current vehicle grilles include irregular shapes, ovals, polygons etc., while others have no slats or bars and yet still fall within the scope of the invention.
The common feature of the grille overlay 10 is the addition of a number of inward protruding clips 32 that are integrally formed within the horizontal slats 28 and/or the vertical bars 26. The clips 32 have a bevel 34 on an interior surface 36, with the clip 32 configured to have sufficient resiliency to allow the clip 32 to be deflected over an exposed edge of a vehicle grille and snap into place. The clips 32 are integrally formed within the body 20 and include a straight shank 38 having a distal end 40. The bevel 34 extends outward from the shank 38 forming a right angular ledge 42, with the ledge 42 having a width sufficient to grip the existing vehicle grille. FIGS. 3–5 and 8–10 show the clips 32 in cross section.
Since the automotive grilles vary in shape and design the clips 32 illustrated are only representative, as the length, width and location may vary and still maintain the requisite shape and surfaces to function effectively. In some cases the clips 32 retain the overlay body 20 on the vehicle grille, and studs or protruding rectangular spacers orient the grille overlay 10, thus permitting the clips 32 to function appropriately.
The snap-on automotive grille overlay 10 is formed from a thermoplastic material such as acrylonitrile butadeine styrene (ABS), poly vinyl chloride (PVC), cellulose, polyethylene, polystyrene or polypropylene, and the chrome plating on the thermoplastic is produced by electroplating methods well known in the art and in common practice.
In order to prevent vibration from separating the overlay from the vehicle grille and to minimize noise levels, a cushioning material 44 may be attached to an inside surface of the thin-walled grille overlay body 20, as shown in FIG. 2. The cushioning material 44 can consist of double-sided adhesive tape or a foam coating that preferably consists of sprayed-on polyurethane.
In order to attach the grille overlay 10 to a vehicle, the overlay body 20 is placed on the existing vehicle grille and aligned accurately to the similarly formed mating parts. The overlay body 20 is then physically pressed into place, expanding the clips 32 until they deflect sufficiently to snap over the grille in the appropriate areas. For removal the opposite procedure is followed.
While the invention has been described in detail and pictorially shown in the accompanying drawings, it is not to be limited to such details, since many changes and modifications may be made to the invention without departing from the spirit and scope thereof. Hence, it is described to cover any and all modifications and forms which may come within the language and scope of the appended claims.
