Abstract
This invention relates to a retraction and extension mechanism for extending or retracting a set of telescopic supports that connect a mirror head (10) to a mirror mounting bracket (11). It comprises a mirror mounting bracket (11) with a first tube (18) projecting from the mounting bracket (11). The mirror head (10) has a support (19) projecting from it that locates into and slides back and forth within the first tube (18). A roller (34) is mounting with respect to the support (19) and cable (29) is attached at one end with respect to the first tube (18) and a point between the roller (34) and the mirror head (10). It extends to and around the roller (34) and into the mirror head (10). The other end of the cable (29) extends into and is attached with respect to the first tube (18). A capstan (31) is located within the mirror head (10) and engages the cable (29). A motor (47) drives the capstan (31) in either direction to cause the mirror head (10) to extend or retract with respect to the mirror mounting bracket (11).
