Abstract

Disclosed is a rear view mirror assembly of the antiglare, "day or night", type which is readily attachable, such as to the face of an existing rear view mirror in a motor vehicle.

The mirror assembly comprises a mirror unit (26) operable between two angularly displaced reflective positions. A cam lever (24) comprising first and second cams (48, 54) cooperates with first and second cam followers (36, 38) to move the mirror unit between the two positions. The mirror assembly preferably includes adhesive strip means (22) to secure the assembly to a support. The cam followers are preferably located on the rear wall (40) of the mirror unit such that vertical movement of the cam lever pivots the mirror unit between the operable positions, one for day driving and one for night driving. This simple, vertical actuating movement minimizes forces tending to displace the mirror assembly from the support.

Claims

1. An antiglare motor vehicle rear view mirror assembly comprising:

a mirror unit operable between two angularly-displaced reflective positions;

first and second cam followers associated with said mirror unit; and

a cam lever comprising first and second cams operable with said first and second cam followers to move said mirror unit between said operable positions, said cam followers being formations on a rear wall of said mirror unit.

2. An antiglare mirror assembly according to claim 1 wherein said mirror unit is pivotally engaged with a housing that supports said cam lever and encloses said first and second cams, said cam lever being vertically actuatable to move said cams within said housing to pivot said mirror unit between said operable positions.

3. An antiglare mirror assembly according to claim 2 wherein said first and second cam followers comprise cam following surfaces inclined from positions farther from said rear wall of said mirror unit at their tops, to positions closer to said rear wall at their bottoms;

said first cam follower comprises a cam-following surface that at its top is spaced from and faced toward said rear wall and at its bottom is fixed to said rear wall; and

, said second cam follower comprises a cam-following surface that faces outwardly from said rear wall.

4. An antiglare mirror assembly according to claim 3 wherein:

said first and second cams comprise inclined camming surfaces adapted to engage said first and second cam-following surfaces, respectively;

said first camming surface extends inwardly from the rear surface of said cam lever from a line of juncture at the top of said first camming surface and above an opening in said cam lever adapted to receive said first cam follower; and

said second camming surface extends rearwardly from the front surface of said cam lever from a line of juncture at the bottom of said second camming surface and below an opening in said cam lever adapted to receive said second cam follower.

5. An antiglare mirror assembly according to claim 4 that further includes hinge means attached to the tops of both said mirror unit and said housing.
