Abstract

An antiglare rear view mirror having an actuator assembly formed with a bearing surface at one end and a rotatable positioning member at the other end that are mounted between a pair of projecting flange members formed on the housing which carries the mirror element and in which the flange members are drawn towards each other for placing the actuator assembly in compression to thereby ensure that the housing maintains its position when moved to the "day" position or the "night" position.

Claims

1. An anti-glare rear view mirror comprising a housing which supports a mirror element having two reflecting surfaces of different reflecting powers, said housing including a back wall integrally formed with forwardly extending upper and lower flange members each of which has an elongated well formed therein, said back wall having a first aperture formed therein, a second aperture formed in said well in the lower flange member, a support extending through said first aperture into the interior of said housing, an actuator assembly in said housing including a body portion made of a plastic material and rigidly connected to one end of said support, said body portion having a bearing surface formed at the upper end thereof located in said well in said upper flange member for allowing said housing to pivot about a first horizontal axis relative to said body portion, an elongated cylindrical member located in said well in said lower flange member for rotation about a second horizontal axis and being formed with a tab member which extends through the second aperture and is accessible for manual movement between first and second positions, a flexible hinge connecting the lower end of said body portion to said cylindrical member whereby movement of said tab member between said first and second positions causes said cylindrical member to rotate about said second horizontal axis with resultant pivotal movement of said housing about said first horizontal axis so as to present one or the other of said reflecting surfaces to the viewer, and means connecting said upper flange member to said lower flange member so as to draw said flange members towards each other and thereby apply a preload to said body portion and said cylindrical member at said flexible hinge to ensure that said housing maintains its position when placed in said first position or in said second position.

2. An anti-glare rear view mirror comprising a housing which supports a mirror element having two reflecting surfaces of different reflecting powers, said housing including a back wall integrally formed with forwardly extending upper and lower flange members each of which has an elongated well formed therein, said back wall having a first aperture formed therein between said wells in the upper and lower flange members, a second aperture formed in said well in the lower flange member, a support extending through said first aperture into the interior of said housing, an actuator assembly in said housing including a body portion made of a plastic material and having a central portion thereof rigidly connected to one end of said support, said body portion having a bearing surface formed at the upper end thereof located in said well in said upper flange member for allowing said housing to pivot about a first horizontal axis relative to said body portion, an elongated cylindrical member located in said well in said lower flange member for rotation about a second horizontal axis and being integrally formed with a tab member which extends through the second aperture and is accessible for manual movement between first and second positions, a flexible hinge made of plastic material integrally connecting the lower end of said body portion to said cylindrical member whereby movement of said tab member between said first and second positions causes said cylindrical member to rotate about said second horizontal axis with resultant pivotal movement of said housing about said first horizontal axis so as to present one or the other of said reflecting surfaces to the viewer, and a strap comprising a pair of arms interconnected by a cross member, each of said arms having a hook portion at the opposite ends thereof for connecting said upper flange member to said lower flange member so as to draw said flange members towards each other and thereby apply a preload to said body portion and said cylindrical member at said flexible hinge to assure that said housing maintains its position when placed in said first position or in said second position.
