Detailed Description of the Preferred Embodiment
FIGS. 1-6 illustrate an auxiliary, external rearview mirror apparatus for motor vehicles according to a presently preferred embodiment of the invention. The auxiliary mirror apparatus is generally designated by reference numeral 10 and comprises an auxiliary mirror member 12 and first and second support arms 14 and 16 for attaching the auxiliary mirror member to an existing external mirror member of a vehicle.
Auxiliary mirror member 12 comprises an auxiliary mirror 18 supported within an auxiliary mirror housing 20. Auxiliary mirror 18 may be flat or of convex curvature as known to those skilled in the art, and is mounted within auxiliary mirror housing 20 in any suitable manner. As best shown in FIGS. 2 and 4, auxiliary mirror housing 20 comprises a molded plastic housing formed to have an inner section 22 at which the support arms are attached, and a generally streamlined outer section 24 which will be described in greater detail hereafter.
Support arms 14 and 16 are attached to auxiliary mirror member 12 by a universal mounting generally designated by reference numeral 32. More particularly, and as shown in FIG. 6, mounting section 22 of auxiliary mirror housing 20 is formed to have a generally spherical-shaped recess 40 which is adapted to receive a generally spherical, ball-shaped element 42 that is capable of moving universally within recess 40. A cylindrical-shaped projection 44 extends outwardly from ball element 42 and is adapted to extend through aligned apertures 46 and 48 adjacent the ends of support arms 14 and 16, respectively. A self-tapping screw 50 or the like is extended axially into projection 44 as shown in FIG. 6 to secure the support arms to the ball element.
Universal mounting 32 permits auxiliary mirror housing 20 to be tilted in various directions relative to the support arms to permit the auxiliary mirror 18 mounted therein to be oriented as desired for proper viewing. In addition, the support arms 14 and 16 are pivotally mounted to mirror member 12 to permit the free ends of the arms to be adjusted closer together or farther apart as indicated by arrows 52 in FIG. 3 to permit apparatus 10 to be mounted to existing external mirrors of different size. FIG. 3 illustrates two positions of arms 14 and 16 in solid and dashed line, respectively.
First and second support arms 14 and 16 include first and second pairs of projections 61 and 62, respectively, formed integrally thereon. Each of the projections 61 and 62 is substantially identical, and as shown in FIGS. 4 and 5, includes a depending portion 63 which extends from the inner side of its respective support arm in a direction generally toward the other support arm, and an extended portion 64 which extends substantially perpendicularly from the outer end of the depending portion in a direction toward the rear of the mirror apparatus. The depending portion 63 is generally in alignment with the rear side 66 of the support arms 14 and 16, and defines with the rear side 66 a first seating surface 68, and the extended portions 64 extend rearwardly of the support arms beyond the rear side 66 thereof to define a second seating surface 69. As best shown in FIG. 5, seating surfaces 68 and 69 form a generally L-shaped seat designated by reference number 67 which is adapted to receive and seat the existing external mirror structure of a vehicle to mount the auxiliary mirror apparatus 10 to the vehicle.
More particularly, as shown in FIGS. 4 and 5, an existing external mirror member 70 on a vehicle typically includes an existing mirror housing 71 having an existing rearview mirror 72 mounted therein. Usually, the existing mirror is somewhat recessed within the existing mirror housing as shown in FIGS. 4 and 5 to define an annular rim 73 on the housing which surrounds the existing mirror. The extended portions 64 of the L-shaped seats 67 defined by the projections 61 and 62 are adapted to extend into the recessed housing such that the second seating surfaces 69 thereon bear against annular internal surface 75 of annular rim 73 above and below existing mirror 72, and the outer edge of rim 73 bears against the first seating surface 68. In essence, the L-shaped seats seat the annular rim 73 of existing mirror housing 71 at two locations above and two locations below the existing miror to mount support arms 14 and 16 of apparatus 10 to existing mirror member 70.
To secure auxiliary rearview mirror apparatus 10 to existing mirror member 70, apparatus 10 further includes a pair of flexible straps 74 and 76. One end of the flexible straps 74 and 76 are secured to one of the support arms 14, and the other end of the straps are adapted to be extended around the back side 86 of the existing mirror housing, inserted through slots 78 in the other support arm 16 (see FIG. 4) and then pulled tightly as shown in FIG. 5 to firmly secure the auxiliary mirror apparatus 10 to the existing mirror member 70. As shown in FIG. 5, a surface of the flexible straps is preferably formed with a plurality of spaced ridges 79 which cooperate with slots 78 to help maintain the straps tightly secured around the existing mirror member.
As shown in FIG. 4, when the auxiliary rearview mirror apparatus of the present invention is mounted to an existing mirror member of a vehicle, the existing mirror remains substantially fully uncovered by the apparatus and can continue to be used for viewing by the driver or other occupant of the vehicle. The projections 61 and 62 engage the housing 71 of the existing mirror above and below the existing mirror without blocking the existing mirror to any significant extent, and the straps 74 and 76 extend around the back of the existing mirror member and also do not cover the existing mirror.
The L-shaped configuration of projections 61 and 62 in conjunction with the flexible straps 74 and 76 permits the auxiliary rearview mirror apparatus 10 to be mounted to existing mirror members of substantially any size or shape. This is best illustrated in FIG. 5 wherein the housing 71 of the existing mirror member defines a substantially thick annular rim 73. Because of the L-shaped configuration of the projections 61 and 62, and because the extended portions 64 of the projections extend rearwardly beyond the back side 66 of the support arms, thick existing mirror housings can be properly seated in the L-shaped seat in a firm, reliable manner. The ability to adjust the length of the flexible straps from the first support arm to the second support arm also permits apparatus 10 to be reliably secured to existing mirror members of diverse sizes and shapes by simply pulling the straps tightly around the existing mirror housing as shown in FIG. 5.
In order to use the auxiliary external rearview mirror apparatus 10 of the present invention, the projections 61 and 62 on the support arms 14 and 16 of the apparatus are positioned to seat the upper and lower edges of the existing mirror housing 71 in the L-shaped seats 67. The support arms can easily be pivoted as required around screw 50 to properly position the projections relative to the existing mirror member. The straps 74 and 76 are then extended around the back of the existing mirror member, inserted through the slots 78 in the support arm 16, and pulled tightly, as shown in FIG. 5, until the auxiliary mirror apparatus is firmly secured to the existing mirror member.
The support arms 14 and 16 are of one-piece construction and are preferably formed of a somewhat flexible, molded plastic material. Accordingly, they are capable of bending somewhat to extend substantially parallel to one another above and below the existing mirror when the straps are tightened. The flexible nature of the support arms in the apparatus of the present invention makes it unnecessary to from the support arms in two or more articulated sections to achieve a proper fit with the diverse existing mirror members on different vehicles; thus, simplifying the construction of the apparatus and reducing manufacturing costs.
As best shown in FIG. 2, when the apparatus 10 is mounted to an existing mirror member 70 the auxiliary mirror member 12 and the auxiliary mirror 18 carried therein extends outwardly from the side of vehicle 80 beyond the existing mirror 70. The streamlined section 24 of housing 20 of auxiliary mirror member 12 is of generally tapered shape, and includes a back housing surface 82 which will be the forwardly facing surface of the housing when the auxiliary mirror apparatus is mounted to a vehicle and which is angled outwardly and rearwardly relative to the vehicle such that the oncoming wind striking surface 82 during movement of the vehicle will tend to strike the surface at a generally acute angle and be deflected outwardly and rearwardly along the surface 82 as shown by arrows 84. In addition, mirror apparatus 10 is mounted to existing mirror 70 such that it essentially follows the line along which the existing mirror member extends from the vehicle and the back surface 82 of the auxiliary mirror housing comprises substantially a continuation of the forwardly facing back surface 86 of the existing mirror housing. As a result, and as shown in FIG. 2, wind striking the existing mirror member will also be deflected outwardly and rearwardly as shown by arrows 87 and be deflected along surface 82 of the auxiliary mirror apparatus away from the vehicle.
Because of the streamlined construction of the auxiliary mirror apparatus, the auxiliary mirror apparatus is able to withstand the force of the oncoming wind while the vehicle is in motion without vibrating to any significant extent. A clear image will thus be provided by the auxiliary mirror at substantially all times. Because the auxiliary mirror member will not vibrate to any significant extent, it will also not transmit any significant vibration to the existing mirror member, and the existing mirror will also remain substantially free from vibration and provided a clear view.
While what has been disclosed constitutes a presently preferred embodiment of the invention, it should be understood that the invention could take numerous other forms. Accordingly, it should be recognized that the invention should be limited only insofar as is required by the scope of the following claims.
