ABSTRACT OF THE DISCLOSURE
A vehicular protection unit particularly for a vehicular lamp having a front or refractive surface.
The unit is an adhesive backed plastic film having a shape substantially conforming to the front or refractive surface of the vehicular lamp. The plastic film is produced from an ultraviolet stabilized polyvinylchloride extrusion. The adhesive is an acrylic based, W stable, pressure sensitive, transfer adhesive. The thickness of the plastic film is about 0.080 inches and the adhesive is about 0.005 inches trick.
Description
~ 3 FIELD ~F THE INVENTION
This invention relates to protective devices for vehicular fog, driving, signal, marker, tail, stop and headlamps.
10 BACKGROUND ~ND SUMNARY OF THE INVE~TION
The breakage of vehicular lamps is a common occurrence and an increasingly large expense for the motoring public to endure. This invention provides a system for alleviating the problem. The device of this invention acts as a zone of deceleration allowing any object impacting the vehicular lamp to dlssipate energy before contacting the front or refractive surface of the vehicular lamp. The invention provides a device that is of simple design, easy to install and fits and protects virtually all vehicular lamps.
There is therefore provided a vehicular lamp protection unit for a vehicular lamp having a front face, the unit comprising:
an adhesive backed plastic film having a shape substantially conforming to the front or refractive surface of the headlight. The unit is attached to a vehicular lamp for use.
The use of a plastic film as protection, as compared to devices presently known to the inventor:
(a) circumvents the need for removing the protective device to clean the vehicular lamp;
(b) requires no disassembly of the vehicle to which the protection is being installed;
(c) becomes and remains virtually invisible on the vehicular lamp after installation;
(d) provides more complete protection of vehicular lamps with relation to the size of the object impacting the vehicular lamp and the force of the impact;
(e) provides protection to a much wider range of vehicular lamps than can reasonably be protected by devices currently available;
(f) completely prevents abrasion or scratching of a vehicular lamp front or refractive surface;
(g) obstructs or absorbs ultraviolet (UV) radiation which arrests or reduces W degradation of plastic vehicular lamps; and (h) allows the usa of vehicular lamp wipers found on some automobiles.
sRIÆF DESCRIPTION OF THE DRAWINGS
There will now be described a preferred embodiment of the invention, with reference to the drawings, by way of illustration, in which like numerals denote like elements and in which:
Figure 1 is a perspective of an embodiment of the invention partly exploded;
Figure 2 is a side view section of a unit according to the invention adhered to a vehicular lamp; and Figure 3 is a cross-saction of an embodiment of the invention showing the laminated se~uence of layers in a form ready for distribution.
DETAILED DE8CRIP~ION OF PR~FERRED EMBO~IMENTS
In Figure 1 is shown a vehicular lamp 10 having a front or refractive surface 12 with a vehicular lamp protection unit comprising a film 14, and adhesive 16 on one side of the film. The unit has a shape substantially conforming to the front or refractive surface of the vehicular lamp. The adhesive is shown at 16. Figure 2 shows the protective unit adhered to the vehicular lamp 10.
The plastic fil~ 14 is preferably an W
stabilized polyvinylchloride (PVC) extrusion, with a thickness of about 0.080 inches. The range of thickness believed to have most utility for application to vehicular lamps, is 0.050 to 0.080 inches. The PVC preferably has an approximate Shore durometer rating of 50A and exhibits cold crack tolerance below -75C. Other materials may be used providing they exhibit more or less equivalent strength, W stability, flexibility, surface quality, solvent resistance and clarity.
The adhesive ~6 is preferably an acrylic based, W stable, pressure sensitive, transfer adhesive about 0.005 inches thick. The adhesive possesses a much greater affinity for the PVC film than for the front or refractive surface of the vehicular lamp surface to which it is to be applied.
Other materials may be used providing they exhibit more or less equivalent strength o~ bond, W
stability, flexibility, clarity, solvent resistance, transferability and ability to function as a filler between the vehicular lamp and the PVC film 14. This avoids formation of air bubbles between the film and the lamp surface, which may impede light transmission.
For sale of the product, the film ~4 and the adhesive 16 are laminated together with a poly coated paper liner 18 (to protect the adhesive before application) in accordance with well known techniques.
Lamination of these components produces a protective device that when applied to a vehicular lamp, for example, a standard low beam 4 x 6 inch headlamp of all glass sealed construction, has provided increased resistance to breakage by an average of 1777%. The protective device also completely prevents the abrasive or scratching of a vehicular lamp front or refractive surface.
The PVC film 14 and adhesive 16 exhibit excellent resistance to solvents such as gases, oils, antifreeze and salts. As well, light transmission is not reduced by more than about 10 to 15%, although that may increase with time due to degradation. This compares well with other methods of protection, some of which block between 25 and 30% o~ the illumination emitted by the vehicular lamp.
The protective device is die cut to fit standard 4 x 6 inch and 5 ~ 7 inch rectangular vehicular lamps, but may be supplied as a universal fit package, 8 x 14 inches or 8 x 18 inches for example, for protecting larger aerodynamic or composite headlamps, fog, driving, marker, signal, tail, rotary and stop lamps etc.
For installation, the vehicular lamp 10 and protective unit should be at room temperature (20 -24C). The vehicular lamp should be cleaned with a cleaning solution, rinsed and dried with a lint free cloth. The protective unit is provided with a paper backing 18 (see Figure 3) on the adhesive 16 and this should be removed. The protective unit is applied to the vehicular lamp using hand pressure with an outward or radial motion beginning at the center of the protective device.
Alternative ~mbodiments A person skilled in the art could make immaterial modifications to the invention described
