Method for blocking glare from the sun and apparatus therefor
In a motor vehicle, a method and apparatus for blocking glare from the sun includes a sun shield which is positioned to block the glare. The sun shield has a connector for attaching the sun shield to the vehicle, and has a plurality of rotationally positionable blades. The sun shield is attached to the vehicle, and one or more of the blades is rotated to block the glare. The sun shield may be attached to the vehicle's visor or to the side window.
The present invention pertains generally to motor vehicles, and more particularly to a method and apparatus for blocking the glare of the sun by interposing a sun shield between the glare and an occupant of the vehicle.
BACKGROUND OF THE INVENTIONDrivers are sometimes bothered by the glare of the sun, particularly when the sun is low upon the horizon such as occurs at dawn and dusk. At these times the sun can shine directly into the driver's eyes thereby creating a hazardous driving condition which cannot always be alleviated by employing the vehicle sun visor. The glare can come directly from the sun, or from reflections off of the drivers vehicle or the roadway.
Devices for shielding a driver from sun glare are known in the art. For example, U.S. Pat. No. 3,415,569 shows a sun visor attachment for a vehicle. The attachment comprises a translucent shield and a mounting bracket for securing the device to the conventional visor of the car, so as to prevent sun glare when the sun is low on the horizon. The attachment is translucent rather than opaque so that a driver can see through the device, and the device will not block the field of view of the drive. The attachment may be pivoted to multiple angles. The attachment can block direct sunlight, or sunlight which is reflected off of the hood of the vehicle.
U.S. Pat. No. 4,570,991 discloses an elongated sun visor panel of either opaque or tinted material which is pivoted on the vehicle body adjacent the juncture between the windshield pillar and the windshield header to enable pivotal movement between a vertical stored position overlying the windshield pillar and a horizontal position partially obstructing either the windshield opening or the side window opening. The elongated panel is preferably divided by a living hinge which provides a longitudinal extending hinge axis by which the panel may be folded to closely overlie the shape of the windshield pillar. A pair of such sun visor panels are preferably provided to enable simultaneous shielding of the occupant relative both the windshield and the side window. The sun visor panel is preferably held in the use position and the stored position by Velcro fasteners, magnets, or a detent associated with the pivot.
U.S. Pat. No. 6,086,132 illustrates a sun spot for use as an extension on a vehicle visor of a vehicle where the vehicle visor has a peripheral edge and the vehicle has an interior roof surface and a windshield. The sun spot comprises: a resiliently flexible injection molded shield member of unibody construction having a clip mechanism for adjusting and removing placement of the sun spot along the peripheral edge of the vehicle visor in approximate alignment with a longitudinal axis of the resiliently flexible injection molded shield member. The resiliently flexible injection molded shield member is sized and proportioned for shielding glare without impairing visibility through the windshield and the resiliently flexible injection molded shield member is retainable on the vehicle visor while flexing for comforming with the placement of the vehicle visor against the interior roof surface or the windshield. The resiliently flexible injection molded shield member is constructed for performing under temperature variations without materially failing.
BRIEF SUMMARY OF THE INVENTIONThe present invention is directed to a method and apparatus for blocking glare from the sun in a motor vehicle such as an automobile, truck, SUV, and the like. A sun shield is attached to a convenient part of the vehicle such as the visor (also known as sun visor) or side window. The sun shield has a plurality of blades which can be selectively rotated by the occupant of the vehicle to block glare from the sun. Glare can be blocked from the eyes of the occupant, or from other body parts such as arms, hands, legs, etc. The present invention can be used to block glare impinging upon the driver of the vehicle, or upon a passenger of the vehicle.
In accordance with a preferred embodiment of the invention, a method for blocking glare from the sun, comprises:
-
- (a) providing a vehicle having an occupant;
- (b) providing a sun shield which is attachable to the vehicle, the sun shield including:
- a connector for selectively attaching the sun shield to the vehicle;
- a swivel attached to the connector;
- a plurality of blades pivotally attached to the swivel, wherein each of the plurality of blades is rotationally positionable about the swivel;
- (c) the occupant using the connector to attach the sun shield to the vehicle;
- (d) the occupant selecting a blade to be rotated; and,
- (e) the occupant rotating the selected blade so that the selected blade blocks glare from the sun.
Other aspects of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring initially to
Sun shield 20 includes a connector 22 for selectively attaching sun shield 20 to the vehicle 500 (also refer to
A swivel 26 is attached to connector 22. Swivel 26 provides an axis about which a plurality of blades 28a through 28e may rotate. Swivel 26 may be a rivet (shown), screw and nut, bolt, post, pin axle, or any other member about which blades 28 may rotate. Plurality of blades 28 are pivotally attached to swivel 26, wherein each of the blades 28 is rotationally positionable about swivel 26 (also refer to
The plurality of blades 28 includes blades 28 having different lengths and having different widths. The different blade 28 lengths and blade 28 widths allows the occupant of the vehicle 500 to optimize the placement of blade 28 with respect to the direction and amount of glare. That is, a blade 28 may be selected such that the selected blade 28 will minimize the amount of viewing obstruction present to the occupant of the vehicle 500 and will still block glare 600 (also refer to
In an embodiment of the invention, the plurality of blades 28 are arranged in order from shortest to longest. This is so that when sun shield 20 is installed on the vehicle, access to the shortest blade 28a is not blocked by the larger blades 28. Also, the size of blades 28 can vary. In the shown embodiment the longest blade 28e is about 13 inches long (L), and the shortest blade 28a is about 8 inches long, and the widest blades 28e and 28d are about four inches wide (W) and the narrowest blades 28a and 28b are about three inches wide. It is also noted that if swivel 26 can be disassembled (such as a bolt and nut), blades 28 may be added to or removed from sun shield 20.
