Detailed Description of the Preferred Embodiment
FIGS. 1-4 illustrate a rear vision mirror assembly 10 for use on a vehicle 12 that may include a housing 14 made of metal or plastic material. The housing 14 is seen to include a pair of substantially vertically extending side walls 16 and 18 with a top walls 20 and bottom wall 22 having a rear wall 24 all joined together with an open end spaced from the rear wall 24 in order to be able to view the vertically disposed mirror 25 positioned within the housing 14. The mirror 25 includes a pair of mirror panels 26 and 28 positioned relative to each other and having reflective faces of different values of intensity. The angle defined by the mirror 25 as seen in FIG. 2 is selected to permit the mirror 25 to be supported in a first position as seen in FIG. 2 in which the panel 26 may be utilized, which for purposes of discussion will be designated as the daytime panel. A second position is provided in which the panel 28 is brought into use, which for purposes of discussion may be considered the night panel.
To permit movement of the mirror 25 between the first and second positions supporting means 30 is provided such that the mirror 25 is rotatably mounted with the mirror panels 26 and 28 facing the open end of the housing 14. The supporting means 30 includes a pivot member 32 that as seen in FIG. 3 may extend between the upper wall 20 and lower wall 22 and may be in the form of a circular member. Positioned on the pivot member 32 are a pair of arms 34 and 36 that may be spaced from each other and extend outwardly from a vertically extending mirror supporting surface 38 having back surface 39. The respective mirror panels 26 and 28 may be formed or secured to the supporting surface 38 in a manner well known.
By providing the first arm 34 and second arm 36 in spaced relation to each other the mirror 25 is free to rotate about the axis of the pivot member 32.
In order to limit the travel of the mirror 25 between its first position and second position stop means 40 as seen in FIG. 2 is provided and mounted within the housing 14 to limit the path of travel of the mirror 25 between the first and second positions. The stop means 40 includes a pair of spaced apart vertically extending tabs 42 and 44 that are disposed rearwardly of the mirror 25 as by securement to the wall 22. The back surface 39 abuts each of the tabs 44 and 42 when the mirror 25 comes to rest in the first or second positions respectively. As seen in FIG. 2 the panel 26 is in position and has the support plate 38 abutting tab 44. In similar fashion tab 42 acts as a stop in the movement of night panel 28 when the mirror 25 is brought into the second position.
In order to maintain the mirror assembly in fixed position to the vehicle 12 mounting means 45 is provided as seen in FIG. 3 and may include a plate 46 secured as by a screw 48 to the vehicle 12 and having a support member 48 extending from the plate 46 and connected as by a swivel joint 50 to the bottom wall 22 of the housing 14. This permits gross adjustment of the housing 14 by the driver of the vehicle 12.
The driver of the vehicle is provided with controlling means 52 illustrated in FIG. 4 to permit manual adjustment of the mirror between the first and second positions from within the vehicle. The controlling means 52 includes bracket or holder 54 that may be secured to the dashboard 56 or other part of the inside of the vehicle. The brace 54 includes an upwardly extending neck portion 56. Within the housing 14 and which may be secured to the bottom wall 22 is a bracket 60 having an aperture 62 extending therethrough. A flexible tubular sheath 64 extends between the neck portion 56 within the vehicle and the bracket 60 within the housing 14. The sheath 64 exits the housing 14 through an aperture 66 on the bottom wall 22 and through a corresponding aperture 68 on plate 46. Mounted within the sheath 64 is a flexible cable 70 secured at one end 72 through an opening 74 within the arm 36 as seen in FIGS. 2 and 3. The opposite end 76 of the flexible cable 70 exits past the neck portion 56 and is secured to a lever 78.
The lever 78 is mounted within the vehicle for angular displacement as by mounting on a rib 80 that extends outwardly from neck 56 and has a pin 82 extending through the lever 78 and rib 80. The cable 70 is secured to the lever at one end 84, and the opposite end 86 is free to be manually controlled by the driver with the free end 86 extending through an opening 88 in the dashboard 56. In this manner movement of the lever actuator 78 effects linear movement of the cable 70 within the sheath 64 which movement is transmitted by the end 72 of the cable 70 to the arm 36 in a manner to effect angular displacement of the mirror 25 between its first and second positions.
Although an illustrative embodiment of the invention has been described in detail herein with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiment, and that various changes and modifications may be effected therein without departing from the scope or spirit of the invention.
