1. An orientable support for a movable mirror associated with a fixed travelling spotlight comprising a chassis (1), a shaft (2) mounted on the chassis (1), a support plate (8), means for driving the shaft (2) in rotation, a spindle (7) which is fixed with respect to the shaft (2), which extends parallel to the support plate (8) and on which the support plate is pivotally mounted, and pivoting means for pivoting the support plate (8) about the spindle (7), characterised in that the pivoting means comprise a flexible cable (18) connected at one end to the support plate (8) by means (19) for permitting a rotary movement of the point of attachment of the cable (18) with respect to the support plate (8), at a point which is spaced from the pivot spindle (7) parallel to the support plate (8), said flexible cable (18) extending through the hollow shaft (2) and being connected at another end to means (22) for regulating the length of the cable (18), said means being fixed with respect to the chassis (1), and means (12) for returning the support plate (8) towards a rest position when the cable (18) is released. |
