1. Technical Field
This invention relates to sun visors and, more particularly, to a power-operated vehicle sun visor.
2. Prior Art
Every person who owns a vehicle of some type is well aware of the consequences when they leave their vehicle parked in the sun. Ultra Violet (UV) radiation freely enters the car through the front windshield and the rear window causing the interior of the car to be considerable warmer than the ambient temperature outside. Since the heated air inside can not escape an enclosed vehicle, the heat is transferred to surfaces on the interior thereof, such as the dashboard and the steering wheel, in effect causing the car's interior to become like an oven. This heating effect is not only uncomfortable to a driver once they reenter the vehicle, but heat transfer can cause permanent and serious damage to the interior surfaces of the car including, but not limited to, cracking and discoloration of surfaces. To prevent this from happening, the use of manual sun visors has become a common practice.
Manually placed and adjusted sun visors for temporarily covering the windshield of an automotive vehicle are nearly ubiquitous, available in a plethora of shapes, sizes, and colors, providing ample testimony for the need to protect the dashboard of contemporary motor vehicles. Unfortunately, forgetfulness on the part of the motor vehicle operator often results in an overheated vehicle or, worse, a damaged dashboard, when the simple, manually placed sun visor is absent from its intended position.
Accordingly, a need remains for a power-operated vehicle sun visor in order to overcome the above noted shortcomings. The present invention satisfies such a need by providing a power-operated vehicle sun visor that is easy to use, has electric and motorized means of operation. Ti improve safety, such a sun visor only operates when the engine is turned off. Such a vehicle sun visor advantageously eliminates the clutter and hassle associated with storing and putting up the more conventional manual sun visors that have inundated the market. The power-operated vehicle sun visor allows for a quick and convenient way to cover both a vehicle's windshield and rear window in order to reduce interior heating of the vehicle and the damage associated therewith.
In view of the foregoing background, it is therefore an object of the present invention to provide a power-operated vehicle sun visor. These and other objects, features, and advantages of the invention are provided by a power-operated visor assembly for shielding undesirable sunlight from penetrating into an interior of the vehicle.
The visor assembly includes first and second coextensive shades formed from opaque material for advantageously reflecting sunlight outwardly and away from the vehicle. Such first and second shades are sized and shaped in such a manner that the first and second shades become nested subjacent to a windshield and partially intercalated within a selected portion of the vehicle frame surrounding the windshield.
The first and second shades are situated within a slot of the vehicle frame such that an outer edge portion of each of the first and second shades becomes hidden and directed along a travel path defined by the vehicle slot. Each of the first and second shades has a centrally registered longitudinal axis extending substantially parallel to a longitudinal length of the vehicle in such a manner that the axes are equidistantly positioned inwardly of the vehicle frame.
The first and second shades further include medially registered inner edge portions extending substantially parallel to the longitudinal axis of the vehicle frame. Such inner edge portions are juxtaposed side-by-side and are formed from rubber material such that a continuous seal is created between top and bottom edge portions of the vehicle window when the first and second shades are biased to the extended positions.
First and second pairs of guide tracks are intercalated within the vehicle slot and securely conjoined to a top surface of the first and second shades respectively. Such a first pair of guide tracks is equidistantly spaced from one of the axes wherein one of the first and second pairs of guide tracks lays adjacent to the vehicle slot and another of the first and second pairs of guide tracks lays adjacent to the longitudinal axis of the vehicle respectively. The first and second guide tracks are preferably attached to a top surface of the first and second shades respectively, and extend parallel to a longitudinal length of the first and second guide tracks respectively. Each of the first and second guide tracks may have a corrugated top surface for being operably engageable with the sprockets as the sprockets rotate about a fulcrum axis registered with the first and second drive shafts respectively.
The present invention further includes a power mechanism for selectively positioning the first and second shades between retracted and extended positions defined along a horizontal roof portion of the vehicle frame and a sloped window portion of the vehicle frame. The user can conveniently extend and retract one of the first and second shades while another of the first and second shades remains stationary.
The power mechanism preferably includes first and second motors medially seated proximate to the horizontal portion of the vehicle frame and above the sloped window portion thereof wherein the first and second motors are nested within the vehicle slot. Such first and second motors are preferably medially situated and equidistantly offset from the longitudinal axis of the vehicle such that the controller can be easily coupled thereto.
First and second elongated and rectilinear drive shafts are operably engaged with the first and second motors respectively. Each of the first and second drive shafts has opposed end portions traversing a longitudinal length of one of the first and second pairs of tracks respectively. Such first and second drive shafts span across approximately one-half a horizontal width of the vehicle window respectively. The first and second drive shafts are further preferably axially registered along a rectilinear path situated orthogonal to the travel path of the first and second shades respectively.
A plurality of annular sprockets is included that have serrated outer surfaces radially spaced about the opposed end portions of the first and second drive shafts respectively. A controller is housed within a compartment of the vehicle such that a user seated within the vehicle can conveniently readily access the controller during operating conditions. Such a controller is electrically coupled to a power supply source and to the first and second motors. The controller instructs the first and second motors to rotate in clockwise and counterclockwise directions for operably transferring the first and second pair of guide tracks through the vehicle slot.
