Car rearview mirror
First Claim
1. A car rearview mirror, comprising:
- a mirror unit having a reflected surface on a front thereof, a hemispheric convex surface on a back thereof, said mirror unit further being provided with two windows;
means for supporting said mirror unit, said supporting means having a hemispheric concave surface; and
means for forcing said hemispheric convex surface to said hemispheric concave surface to fit said mirror unit to said supporting means in such a manner that said mirror unit is pivotable in relation to said supporting means;
said forcing means including a central support provided on said mirror unit, two end supports provided on said supporting means corresponding to said windows of the mirror unit, and an elongated leaf spring that is retained at a center and opposite ends, respectively, thereof by means of said central and two end supports in a bowed state,said two end supports being fitted to said windows of said mirror unit to prevent said mirror unit from being oscillated about an axis of said hemispheric convex surface.

Abstract
A car rearview mirror comprises a mirror unit having a hemispheric convex surface formed thereon and a central support formed integrally therewith on the opposite side to the hemispheric convex surface to receive a leaf or wire spring at the center of the latter, and a mirror housing having a hemispheric concave surface formed thereon and two end supports formed integrally therewith to retain the spring at the opposite ends, respectively, of the latter. The hemispheric convex surface of the mirror unit is fitted to the hemispheric convex surface of the mirror housing in such a manner that the mirror unit can be pivoted in relation to the mirror housing. To assemble the rearview mirror, the spring is bowed and supported at the center thereof on the central support and at the opposite ends thereof on the two end supports. Namely, the car rearview mirror can have a reduced number of parts.

13. A car rearview mirror, comprising:
-
a mirror unit having a reflecting surface on a front thereof and a hemispheric convex surface on a back thereof; means for supporting said mirror unit, said supporting means having a hemispheric concave surface; and means for forcing said hemispheric convex surface to said hemispheric concave surface to fit said mirror unit to said supporting means in such a manner that said mirror unit is pivotable in relation to said supporting means; said forcing means including a central support provided on said mirror unit, two end supports provided on said supporting means, and a wire spring having a circular section and being retained at a center and opposite ends, respectively, thereof by means of said central and two end supports in a bowed state, said wire spring being supported at the center thereof in a substantial point contact on a pin fixed to a top of said central support perpendicularly to said wire spring, one end of said wire spring being looped and fixed to one of said two end supports with a screw, the other of said end supports having two abutments extending axially of said screw and between which a through hole is formed, and said wire spring being ended at the second end thereof by a crank consisting of a bend extending generally in parallel with the central axis through said looped end and which is to be set between said two abutments to prevent said wire spring from rotating about the axis of the two abutments and an extreme portion contiguous to said bend and extending straight in a direction away from the first end, said extreme portion inserted into said through-hole and retained at a wall of said through-hole.
