Description
Technical Field
This invention relates to automotive accessories and more particularly to a device for concealing automotive headlights when they are not in use.
Background Art
Various structures have been provided to enhance the appearance of automobiles by concealing the headlights. Such structures are typically complicated and result in increased maintenance problems.
Several known structures include a member that smoothly conforms to the contour of the vehicle body when the headlights are not in use. This design favorably influences the aerodynamics of the vehicle. These structures, however, generally pivot to a position where the headlights are raised above the contour of the vehicle body when the lights are in use. In this raised position, the headlights adversely affect both the aesthetic appearance and the aerodynamics of the vehicle.
Those concerned with these and other problems recognize the need for an improved device for concealing vehicle headlights when they are not in use.
Disclosure of the Invention
The present invention provides a contoured concealment lens for vehicle headlights. The lens conforms to the contour of the vehicle body and includes an internal cavity that is selectively filled with an opaque fluid when the headlights are not in use. The concealment lens has no adverse influence on the aerodynamics of the vehicle when the lights are in use and it is aesthetically compatable with the vehicle at all times.
An object of the present invention is the provision of an improved concealment device for vehicle headlights.
Another object is to provide a concealment device for vehicle headlights that has no influence on the aerodynamics of the vehicle.
A further object of the invention is the provision of a contoured concealment lens that is aesthetically pleasing whether or not the vehicle headlights are in use.
Still another object is to provide a contoured concealment device that is simple in structure and easy to maintain.
A still further object of the present invention is the provision of a contoured concealment device for vehicle headlights that is reliable.

FIG. 2 is a top plan sectional view taken along line 2--2 of FIG. 1, and showing the position of the top portion of the concealment lens and the headlight in dashed lines;
FIG. 3 is an enlarged side elevation sectional view taken along line 3--3 of FIG. 2, showing the attachment of the lens to conform to the contour of the vehicle body and the vacuum system used to selectively fill the lens cavity with an opaque fluid;
FIG. 4 is a greatly enlarged side elevation sectional view showing the location of the ball check valve at the inlet to the vacuum line when a vacuum is applied and the lens cavity is filled with opaque fluid;
FIG. 5 is a greatly enlarged side elevational sectional view illustrating the vacuum selector switch positioned to prevent the application of a vacuum on the lens cavity;
FIG. 6 is a sectional view similar to FIG. 4, but showing the location of the ball check valve when no vacuum is applied and the opaque fluid is drained from the lens cavity; and
FIG. 7 is a greatly enlarged side elevation sectional view showing the opaque fluid reservoir located at the bottom of the lens cavity.
Best Mode for Carrying Out the Invention
Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, FIG. 1 shows the contoured headlight concealment device (10) of the present invention installed on the forward portion of a vehicle (2) such that the outer surface of the concealment device (10) smoothly conforms to the contour of the vehicle body (4) and overlies each of the vehicle headlights (6).
As most clearly shown in FIGS. 2 and 3, the concealment device (10) includes a transparent lens (12) having an internal cavity (14). It is to be understood that the lens (12) could be formed of shatter-resistant glass, plexiglass, or any other suitable transparent material. The upper portion of the cavity (14) converges to a point (FIG. 2, dashed line) and is disposed beneath the vehicle body (4). The lower portion of the cavity is co-extensive with and overlies an opening (8) in the vehicle body (4) located forward of the headlight (6). The concealment device (10) and the vehicle body (4) are interconnected by a sealing bracket (9) which is attached to the body (4) adjacent the inside surface of the opening (8).
As best shown in FIGS. 2, 4 and 6, the upper portion of the cavity (14) terminates in a vacuum port (16) that is connected to a vacuum line (18). An enlarged area (20) is formed in the cavity (14) adjacent the vacuum port (16) and receives a lightweight ball (22).
Referring now to FIGS. 3 and 7, the lower portion of the cavity (14) is in communication with a fluid reservoir (30). The reservoir (30) has a fluid volume sufficient to fill the cavity (14) and the enlarged area (20) with a safe reserve level remaining. A flexible diaphragm (32) is attached to the upper portion of the reservoir (30) by retainer (34). The diaphragm (32) is positioned adjacent a vent (36) in the top of the reservoir (30).
As illustrated by FIGS. 3 and 5, the vacuum line (18) is connected to a distribution diaphragm (40) that is in simultaneous communication with the cavities (14) of both lenses (12). The diaphragm (40) is connected by line (42) to a vacuum selector switch (50). The switch (50) is also connected by line (44) to the vehicle's engine vacuum canister (not shown). The switch (50) is mounted in the vehicle passenger compartment within easy reach of the operator.
The vacuum selector switch (50) includes a body section (52) having a vacuum opening (54), a vent opening (56), and a common opening (58). The common opening (58) is in communication with the distribution diaphragm (40) through line (42). The interior of the body section (52) slidably receives a block (60) having a passageway (62) formed therein. The block (60) is selectively positioned by movement of the finger tab (64).
Any suitable opaque fluid (70) can be used in the device (10). For example, mercury or an alcohol solution tinted to match or be compatable with the color of the vehicle body (4) would provide an opaque fluid (70) having a low freezing point.
In operation, the internal cavity (14) is selectively filled or emptied of the opaque fluid (70) by selective positioning of the vacuum control switch (50). When the switch (50) is positioned as shown in FIG. 3, the vacuum from the vehicle's vacuum canister is applied to the cavities (14) of each device (10) through the distribution diaphragm (40). The vacuum applied draws the opaque fluid (70) up from the reservoir (30) to completely fill the cavity (14) and the enlarged area (20) until the fluid (70) contacts the lightweight ball (22) and it floats up to seat against the vacuum port (16) as shown in FIG. 4. The opaque fluid (70) thus will fill the cavities (14) to conceal the headlights (6) when they are not in use. It is to be understood that the switch to operate the headlights (6) could be incorporated in or activated by the vacuum control switch (50) or separately activated.
When the switch (50) is positioned as illustrated in FIG. 5, the cavities (14) are vented to the atmosphere through vent opening (56). The opaque fluid (70) then flows by gravity into the reservoir (30), thereby allowing the passage of light from the headlight (6) through the transparent lens (12).
Thus, it can be seen that at least all of the stated objectives have been achieved.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that, within the scope of the appended claims, the invention may be practised otherwise than as specifically described.
