Adjustable Mirror Mount

This adjustable mirror mount includes resilient restraint blocks which prevent excessive mirror movement, and possible mirror damage, as a result of dropping or the like.

Mirror 10 is a flat first-surface mirror which is mounted at three points 11, 12 and 13 relative to base 14. Each of the three mounting points is as shown in Fig. 3, and includes metallic mounting block 15 having an adjusting screw 16 and a spring biased pin 17. Pin 17 freely slides in an opening 18 which accurately aligns the center of the pin with the center of the adjusting screw 16. Thus no mirror bending movement occurs. Pin 17 is bias toward the adjusting screw by leaf spring 19.

Each mounting block 15 includes a cylindrical boss 22 which is located concentric with opening 18. This boss provides a close tolerance fit to locating holes 23 in base 14.

Three mirror restraint blocks 24, 25 and 26 are provided to limit movement of the mirror 10 toward the base 14. As seen in Fig. 2, the ramp-like edge 27 of each block is spaced from the mirror's edge and prevents extreme shifting of the mirror 10 so as to, for example, engage the surface 28 of a mounting block 15.

Each of the mounting points includes a probe hole 20 such that a tool, represented by broken line 21 in Fig. 3, can be inserted to depress the leaf spring 19 and facilitate, for example, mirror replacement.
