Spring detent for foldable side mount rear view mirror
First Claim
1. A side-mounted vehicular rear view mirror of the type which comprises a hollow gooseneck support arm secured to a bodyside mount which permits the gooseneck arm and a mirror assembly carried outboard of the vehicle thereby to be folded from a predetermined, mechanically detented viewing position toward the vehicle bodyside, the gooseneck arm having a first, essentially upright length which is adapted to be secured to said mount and, integral therewith but angularly displaced relative thereto, a second outwardly extending length adapted to carry said mirror assembly wherein the improvement comprises:
- a longitudinal detent structure formed in the side wall of the upright length of said gooseneck arm;
a semi-cylindrical bearing surface formed in said body mount to receive and support said upright length for rotation therein; and
a spring clamp having opposed feet secured to said bodyside mount on opposite sides of said surface, a resilient spring portion clamping said upright length into said surface, and flexor portions interconnecting the spring portion and said feet, said spring portion having a detent structure formed therein which is cooperable with said gooseneck arm detent structure to yieldably maintain said gooseneck arm in said viewing position and to yield as permitted by said flexor portions to permit the folding of said arm relative to said vehicle body side.

Abstract
A side mounted vehicular rear view mirror of the type which comprises a hollow tubular steel gooseneck support arm which can be rotated forwardly or rearwardly relative to a clamp type mount on the vehicle body to fold the mirror against the vehicle body side to prevent damage to the mirror in, for example, a vehicle carwash or other narrow passageway. The clamping structure comprises a mount having longitudinally spaced semi-cylindrical bearing seats adapted to receive a length of the gooseneck arm and a spring steel clamp having opposing complemental bearing surfaces and an arcuate detent which engages a straight sides slot formed in the gooseneck arm where it overlies the spaced apart bearing seats. The spring clamp flexes to provide a relatively high break away torque and a relatively low continued rotation torque.
