ABSTRACT:
An adapter is disclosed which allows the secure installation of a lighting fixture to a lighting track and which lies flush with the face of the track in its locked condition. The adapter includes a pair of wing-like pull down levers pivotably mounted to a base. A resilient retention member is engaged by cam walls extending from the lever so that when the lever is pivoted to a flush, locking position the resilient members are moved transversely outwardly and become wedged against the inner walls of the lighting track, thereby to secure the adapter to the track. The lighting fixture can be locked in a desired horizontal and vertical orientation by the operation of a single actuator arm. Rotation of the actuator arm from an unlocked to a locked position causes two friction plates to come into engagement, thereby to establish a braking action that prevents further movement of the lighting fixture in the vertical direction, and also moves a pair of clamps into operative engagement with the lighting fixture, thereby to limit its horizontal rotation.
