ABSTRACT:
There is disclosed an improved adjusting mechanism for an articulated headlamp construction or the like. The adjusting mechanism is comprised of a minimum number of parts, namely a housing, a scroll member and an adjusting rack member. The scroll member provides the input member for the mechanism and upon rotation thereof rotative movement thereof is transformed into transitory movement of the rack member pursuant to a spiral or scroll projection that is engaged with teeth on the adjusting rack member. The transitory movement of the adjusting rack member will correspondingly produce pivotal movement of the articulated headlamp component. If desired, the adjusting rack member may be curved so that the movement of the end thereof affixed to the headlamp will closely approximate the pivotal movement of the headlamp component. Further, there is disclosed a combination of an articulated headlamp component and an adjusting mechanism of the type having a rotatable input member and a output member operatively connected thereto for transitory movement upon rotation of the input member. In this regard, the output member is provided with a socket construction on the end thereof which is engaged with a ball component of a ball-headed screw affixed to an articulated headlamp thereby eliminating the need for brackets and individual socket components affixed to the headlamp as is the standard practice in the art.
