This invention relates generally to sun visors for use in an automobile or other equipment with a window or windshield, where the sun visor is automatically positioned to block direct rays of sunlight from interfering with the vision of the operator or the passenger, and the sun visor is automatically repositioned to adapt to changes in environmental conditions, the position or orientation of the vehicle, or the location of the operator's eyes.
Automobiles and other equipment containing windows and windshields often feature visors which can be manually adjusted to block sunlight from directly shining into the operator's or passenger's eyes. In order to be effective, manual visors must be positioned to effectively block direct sun rays entering through the vehicle or equipment windshield or window without impairing visibility. As a result, an operator must reposition manual visors continuously as the vehicle or equipment changes direction or orientation. The operator also must manually reposition the visor to account for differing angles of sunlight, such as when the sun changes its position in the sky, or the vehicle or equipment adopts or leaves an inclined position. In some cases, a visor may be ineffective for an operator or passenger with a short height or lower posture. It is also difficult and dangerous to rotate them from the front side while driving. They also block the view of stop lights and traffic signals. In all these situations, the constant need to adjust and reposition a manual sun visor in response to changing environmental and operating conditions can create a distraction that can lead to accidents or can have other safety concerns.
While manual sun visors may be suited for some applications, the safe operation of vehicles and other equipment requires an automatic sun visor system that repositions the visor to optimally shield the operator's eyes from direct sunlight, while minimizing the obstruction of the operator's view. In addition, such an automated system should respond rapidly to environmental and operational changes including: changing position of the sun, changing incline of the vehicle or equipment, change in direction or orientation of vehicle or equipment, changes in operator's or passenger's posture, and changes in the intensity of sunlight entering the window or windshield.
The present invention is directed to a device that satisfies the present need for an automatic sun visor apparatus to position a visor within the window or windshield frame of the vehicle or other equipment so as to block direct rays entering the window and interfering with the operator's or the passenger's vision, and also minimizing obstructions to the view of the operator. In general, the invention uses a specialized apparatus connected to an electronic control unit common in modern automobiles and other equipment to collect operational and environmental data concerning the sun position and the location and orientation of the vehicle or equipment to optimally position the visor and continually adjust the position in response to changing environmental and operational information.
Embodiments of the invention are depicted in the attached figures. Descriptions cover the presently contemplated mode for carrying out the invention of an automatic sun visor assembly. While the embodiments are presently considered to be practical implementations, it is to be understood that the present invention is not limited to the disclosed embodiments, but on the contrary is capable of implementation in various modifications and equivalent arrangements included within the general description of the invention.
The invention will be described in conjunction with the attached drawings in which referenced numerals designate elements, and wherein,
The Winder 48 and coiled Spring Wire 54 are located within a Housing 40. The Housing 40 should be sized to minimize the space occupied in the area of the operator and may be roughly the size of a soda can (5 inches in height and 2.5 inches in diameter) or smaller. The Housing 40 is designed to attach to the interior of the vehicle or equipment adjacent to the window or windshield. In an automobile, the Housing 40 may be attached to the A-pillar or any other suitable structure near the window or windshield frame. The Winder 48 is housed in a Carriage 44, which in turn is located within the Housing 40. In an embodiment of the invention, the Winder 48 is directly encased within the Housing 40 wherein the Carriage 44, unlike as shown in
The Carriage 44 enclosed within the Housing 40, has a Winder 48 spinning around a Winder Spindle 63 inserted into the Spindle Opening 46 located along the axis of the Winder 48. In this manner, the clockwise or counterclockwise rotations of the Winder 48 cause the Spring Wire 54 to correspondingly extend or retract out of the Spring Wire Guide 52 thereby bringing about a corresponding movement of the Sun Visor 50. The outward movements of the Spring Wire 54 are limited by inclusion of a Stopper 56 that prevents the Spring Wire 54 from unraveling and falling off the Winder 48.
An embodiment of the automatic sun visor assembly comprises of a spring wire having a first end, a second end, and a length wherein a visor is attached to the second end of the spring wire; a housing fixedly attached to a surface and including a volume wherein the volume further includes a carriage comprising of a winder adapted to wrap or unwrap the spring wire from its first end thereby shortening or unshortening the unwound length of the spring wire, a threading hole adapted to pass the second end of the spring wire therethrough wherein the threading hole is capable of moving in a vertical direction and thereby change an orientation of the spring wire, a rotation mechanism in communication with the housing and the carriage; wherein the rotation mechanism rotates the carriage enclosed within the housing. In an embodiment, the carriage has an inside surface and an outside surface, the winder substantially shaped like a cylinder and including a receptacle disposed along its axis, a winder motor including a spindle where the winder motor is capable of causing a rotational movement in the spindle with the winder motor fixedly attached to the inside surface of the carriage, and the spindle adapted to insert into the receptacle and thereby engage the winder, wherein the spring wire is wrapped or unwrapped over the winder surface upon the winder motor causing rotational movements of the spindle and thereby the winder. In an embodiment, the winder has a top surface, a lateral surface, and a bottom surface, and where the second end of the spring wire and the visor are attached with a visor attachment artifact, and the top surface of the winder includes a retention receptacle adapted to retain the visor attachment artifact when the spring wire is completely wound to the winder. In an embodiment, the winder surface includes grooves to facilitate the winding and unwinding of the spring wire.
Illustrated in
The Vertical Motor 64 drives a Pinion 60 which has a plurality of grooves that engage a Rack 58. Correspondingly, as the power gets transferred by the Vertical Motor 64 to its Vertical Spindle 65, it rotates the Pinion 60 which engages it through by winding and unwinding the grooves and correspondingly moving the Rack 58 vertically within the Rack Guide 42. As the Spring Wire 54 is running through the Spring Wire Guide 52 located on top of the Rack 58, the vertical movements of the Rack 58 effectively change the vertical direction towards which the Spring Wire 54 points. The extension or retraction of the Spring Wire 54, and the position of the Rack 58 thus control the position and angle of the Sun Visor 50.
In an embodiment of the invention, the carriage further includes a vertical motor having a pinion spindle attached to a pinion where the vertical motor is capable of causing a rotational movement of the pinion spindle and thereby the pinion, where the vertical motor being fixedly attached to the inside surface of the carriage, and the pinion further adapted to engage a rack where the rack includes the threading hole adapted to receive the spring wire therethrough, and the rotation movements of the pinion cause the rack to move in the vertical direction; a rack guide adapted to receive the rack and allow it to move in the vertical direction within the rack guide, wherein the rack guide is fixedly attached to the inside surface of the carriage; and where the orientation in the vertical direction of the spring wire is adapted to be changed by the rotational movements of the vertical motor and the pinion. In an embodiment of the invention, the vertical motor includes an electronic interface allowing the rotational movements of the vertical motor to be programmatically controlled by a computer program.
In a typical embodiment, the vehicle ECU receives signals from sensors that can include light sensors, occupant head position, compass, and time of day. The ECU uses these input signals to determine an X, Y, and Z location to position the Sun Visor 50. The ECU or visor controller will determine which of the three visor motors to actuate and duration to actuate them to move the sun visor panel to the correct location. In the current invention, the winder motor includes an electronic interface allowing the rotational movements of the winder motor to be programmatically controlled by a computer program.
As illustrated
In an embodiment of the invention, the outside surface of the carriage has a rotator motor fixedly attached thereupon, the rotator motor further including a rotator spindle whereupon a gear is fixedly attached; the housing further includes a rotator receptor complementary to and adapted to receive the rotator gear such that upon engaging the rotator gear into the rotator receptacle any relative movements between the rotator receptacle and rotator gear are prevented, and where a rotational movement of the rotator spindle results in a rotational movement of the carriage about the rotator spindle acting as an axis and with the rotator receptor acting as a pivot. In an embodiment, the rotator motor includes an electronic interface allowing the rotational movements of the rotator motor to be programmatically controlled by a computer program.
