Abstract
A rear view minor assembly is disclosed in which the minor has a viewing section and an alignment section meeting to form a reflex angle. The alignment section is etched with a targeting image: a cross-hair or the side surface of the vehicle. When the targeting image is aligned with appropriate feature on the side of the vehicle, the reflex angle is such that the minor is properly aligned. Also disclosed is a mirror assembly having viewing section and an alignment section with a clear protective outer layer a selective acceptance layer below the clear protective outer layer, and a colored substrate below the selective layer. When the vehicle operator can see the colored substrate through the selective acceptance layer, which transmits only normal light, the minor is properly aligned.
Description
- This application is a divisional of U.S. application Ser. No. 12/823,742 filed Jun. 25, 2010, which is a divisional of U.S. application Ser. No. 12/259,713 filed Oct. 28, 2008, now abandoned, both of which are hereby incorporated by reference.
- The present development relates to a rear view minor that facilitates properly aligning the minor.
- Minor systems are provided on automotive vehicles to aid the operator of the vehicle in viewing other vehicles while merging, lane changing, turning, reversing, etc. Mirrors can provide a view of the vehicles and objects in the vicinity of the operator's vehicle. However, the effectiveness of that view depends on proper alignment of the minors. It is known in the art, through customer interviews, car clinics, and survey comments that many vehicle operators do not align their mirrors in an orientation which provides the most information to the operator.
- In particular, it is common for drivers to position their exterior side minors so that they can see the edge of their own vehicle. As illustrated in
FIG. 1 ,side minors vehicle 10. In this position, the images ofvehicles mirrors mirrors - Properly adjusted
exterior minors FIG. 2 . Images ofvehicles viewing regions 16′ and 18′. Also, there is less overlap ofviewing regions 16′ and 18′ withregion 26. Also note that neither ofviewing regions 16′ or 18′ intersects withvehicle 10, thereby making a more effective use of available image area ofmirrors FIG. 1 . - One of the advantages of adjusting the minors so that
viewing region 16 includes a portion ofvehicle 10 is shown inFIG. 3 . Because the operator can view an image of the side of thevehicle 28 inside mirror 12, it provides the operator an object to view during adjustment of the mirror. However, such a position inFIG. 3 corresponds to the improper adjustment illustrated inFIG. 1 . When proper adjustment position such as illustrated inFIG. 2 is used,viewing regions 16′ and 18′ do not overlapvehicle 10, thereby failing to provide a reference point with which to assess the suitability of the adjustment. - To partially overcome maladjustment of the minors by many vehicle operators, some manufacturers provide the vehicle with larger mirrors than would otherwise be required if the mirrors were properly adjusted. Larger mirrors increase weight and aerodynamic drag to the vehicle, both of which penalize fuel economy. Also, the farther the mirrors extend from the vehicle, the greater the likelihood that the vehicle will clip an object in tight conditions such as entering a narrow garage opening or when moving the car close to a booth for collecting a parking ticket or paying a toll.
- A rear view minor assembly is disclosed which has a minor coupled to an angle adjusting mechanism. The mirror has a viewing section and an alignment section which meet to form a reflex angle. The alignment section is etched with a targeting image. In one embodiment, the target image is a cross-hair. In another embodiment the image is an outline of the side surface of the vehicle. Typically, the viewing section, the viewing section, is larger than the alignment section, the targeting section. In one example the viewing section exceeds the alignment section by more than a factor of five in cross-sectional area. In one embodiment, the viewing and alignment sections are uninterrupted, but abutting each other, with the line of abutment being generally vertical.
- The reflex angle is selected so that the target image of the outline lines up with the side surface of the vehicle from the viewpoint of the vehicle. The viewing section as viewed by the operator provides a desired image which excludes all parts of the vehicle. In one embodiment, the alignment section has lower reflectivity than the viewing section.
- Also disclosed is a rear view mirror assembly in which a minor is coupled to an angle adjusting mechanism. The minor has a viewing section abutting an alignment section. The two are aligned with respect to other such that an imaginary, infinite plane of the viewing section and an imaginary, infinite plane of the alignment section intersect form an obtuse angle. The viewing section is more than 10 times larger in surface area than the alignment section. The abutting interface is generally vertical, i.e., more vertical then horizontal in orientation. The minor assembly is coupled to a side of an automotive vehicle with the alignment section proximate the vehicle. The alignment section may have a lower reflectivity than the viewing section. The alignment section is etched with a feature which an operator of the vehicle aligns with a feature of the vehicle to ensure proper minor adjustment.
- In an alternative embodiment, the alignment section has a selective acceptance layer below the clear protective outer layer, and a colored substrate below the selective layer. The selective acceptance layer transmits light rays which are normal to its surface and absorbs non-normal light rays. The obtuse angle is selected so that when the alignment surface is aligned to allow an operator of the vehicle to observe the colored substrate, the viewing section as viewed by the operator provides an image which excludes all parts of the vehicle. The alignment surface is embedded in the viewing surface so that the two top surfaces are flush with each other, or, alternatively, the alignment surface may be applied to the surface of the viewing surface.
- One embodiment includes a minor assembly for a vehicle having an adjustable mounting structure and a mirror having a viewing section and an alignment section. The alignment section has a visual alignment feature that may be viewed to confirm that the viewing section is properly aligned with the adjustable mounting structure.
- Also disclosed is a method for providing a minor assembly for an automotive vehicle. A mirror frame is installed on an outside surface of the vehicle. A mirror adjustment mechanism is installed to the mirror frame. The minor frame has a mirror mounted in which the mirror has a flat surface with a facet, the facet having an alignment feature to indicate when the mirror is properly aligned.
- More drivers will be able to adjust minors properly if an affirmative method is provided for determining when the rear view minor is properly adjusted. Properly adjusted minors afford the driver an improved view of the objects in the vehicle's vicinity which reduces or eliminates blind spots.
- The cross-sectional area of the mirror may be minimized if the manufacturer can be confident that drivers properly adjust the minors. In some cases, manufacturers place larger mirrors on vehicles than strictly necessary, to overcome the problem of maladjusted mirrors giving inappropriate views. With assurance that the viewing angle is adjusted properly, manufacturers would not need to compensate for maladjusted mirrors. The benefits of smaller mirrors are improved fuel economy by reducing the area of cross-section of the vehicle with respect to the direction of travel. Also, rear view minors can be a source of wind noise, which would be lessened with smaller mirrors. Finally, mirrors are known to be clipped by encounters with fixed or moving objects. Examples of fixed objects are mail boxes, garage door openings, toll booths, and telephone poles. Any decrease in the size of the mirror can reduce the overall width of the vehicle, which allows for access to tighter places and a reduced chance of hitting the minor with another object.
- Customer satisfaction may be enhanced because a foolproof method is provided for properly adjusting the mirrors.

FIG. 4 , aminor assembly 30 having a first surface 32 (alternately called a viewing section) and a second surface 34 (alternately called an alignment section) is shown mounted inhousing 36.Housing 36 has anarm 38 for attaching themirror assembly 30 tovehicle 10. In one embodiment,second surface 34 is less reflective thanfirst surface 32.Second surface 34 is etched with a targeting feature, which in one embodiment is a cross-hair 40 to aid in aligning themirror assembly 30 properly. In particular, a feature on the car, such as a door handle (not shown), is designated to be the target point for cross-hair 40 to ensure suitable alignment ofminor assembly 30. - Alternatively, in
FIG. 5 , the targeting feature is a targetingoutline 42 for aligning thefirst surface 32 ofminor assembly 30 is an outline of the outside surface of the vehicle. When, the image of the outside ofvehicle 28 aligns with targetingoutline 42, thefirst surface 32 of themirror assembly 30 is properly aligned. The illustration inFIG. 5 shows targeting outline 42 not quite aligned with the image of the outside ofvehicle 28. When the two are lined up, the first surface ofminor assembly 30 provides a suitable rear view to the operator ofvehicle 10. - Cross-hair 40 and targeting
outline 42 of the outline ofvehicle 10 are etched into the glass surface, in one embodiment. However, cross-hair 40 or targetingoutline 42 could also be painted or marked on or within the glass in any known manner, in other embodiments. - In
FIG. 6 , a top view of thefirst surface 32 andsecond surface 34 are shown. The front faces of the two surfaces form a reflex angle 44 (greater than 180°). - Another way to define the angle is shown in
FIG. 7 in which imaginary, infinite planes extending from the faces offirst surface 32 andsecond surface 34 are illustrated. The two planes intersect with formingobtuse angle 46. - In
FIG. 8 , anadjusting mechanism 48 is shown that allows themirror housing 36 to pivot relative to thearm 38. InFIG. 9 , anadjusting mechanism 50 is shown in whichminor 30 adjusts with respect tohousing 36. Thehousing 36 does not move with respect toarm 38. These illustrations are provided by way of example and are not intended to be limiting. Any known way of providing for adjustment of the mirror, including, but not limited, to known mechanical and electrically-driven adjustment mechanisms may also be incorporated with this development. - In
FIG. 10 , an alternative embodiment of amirror assembly 60 shows that a flat surface minor 62, viewing section, is provided with aninset element 64, alignment section. Alternatively,inset element 64 could be placed proximate the periphery ofsurface 62. - In
FIG. 11 ,element 64 is shown to have 3 layers: a topprotective layer 66, aselective acceptance layer 68, and an opaquecolored layer 70. Theselective acceptance layer 68 transmits only on-axis light, that is, light that is directed normal to the surface oflayer 70. Opaquecolored layer 70 is a colored layer that the driver of the vehicle is only able to see when the driver'seye 71 is aligned such than an imaginary ray emanating from the eye intersectsselective acceptance layer 68 perpendicularly. If the line of sight from the eye is off-axis,selective acceptance layer 68 prevents off-axis light from being transmitted; hence, the driver cannot see opaquecolored layer 70. By careful selection of theangle 72 between the face ofselective acceptance layer 70 and the face ofmirror 62, the driver is able to see opaquecolored layer 70 only when minor 62 is properly aligned.FIG. 11 shows an embodiment in whichelement 64 is placed on top ofminor 62. InFIG. 12 ,element 64 is integrated intoflat surface mirror 62. In one embodiment,selective acceptance layer 68 is formed out of polarizing material. Such material has a narrow cone of acceptance of light which is transmitted, with non-normal light being absorbed. In another embodiment,selective acceptance layer 68 is made from fiber optic cable. These embodiments are provide by way of example and not intended to be limiting. - In
FIG. 11 , a top surface ofprotective layer 66 and bottom surface ofprotective layer 66 are parallel, but are not parallel as shown inFIG. 12 . The shape ofprotective layer 66 is largely immaterial because light passing throughprotective layer 66 is largely unaffected. The orientation ofselective acceptance layer 68 establishes the reference angle with respect to themirror 62 that assures proper alignment. - While particular embodiments of the invention have been shown and described, numerous variations and alternate embodiments will occur to those skilled in the art. Accordingly, it is intended that the invention be limited only by the appended claims.
- As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
