1,212,988. Exterior rear view vehicle mirrors. JOSEPH LUCAS (INDUSTRIES) Ltd. 18 April, 1968 [26 May, 1967], No. 24610/67. Heading B7J. A vehicle exterior rear view mirror comprises a base 12, having resilient arms 13 extending upwardly therefrom, and a member 18 connecting said arms to a head 23, the upper ends of said arms being urged towards each other and defining an aperture 15 adapted to receive a corresponding shaped spigot of said member 18, the arrangement being such that rotation of said head will cause the spigot to rotate in aperture 15 forcing the arms apart, but on release of the head the resilience of the arms will cause the head to return to its original position, or 180 degrees with respect thereto if the rotation is greater than 90 degrees. The end of member 18 remote from the spigot is formed with a ball 22 received in a socket 28 of a member 25. Said member 25 is generally cylindrical and formed with a groove 26 gripped by the edge of an aperture 24 in the back wall 23 of the head. The part of member 25 forming the recess 28 comprises four axial fingers having rotatable thereabout a sleeve 31. Posts 32 of said sleeve co-operate with ramp surfaces forming the base of a groove 27, rotation of the sleeve causing the fingers to grip the ball. The mirror parts may be formed from moulded synthetic resin and the reflective surface of the head formed by chromium plating a specular surface.
