The present invention provides an adjustment mechanism by which a luminaire may be adjusted and secured along an arc. The adjustment mechanism includes a mounting bracket, adjustment bolt, adjustment brace, which is attached to the optical housing of the luminaire, and a positioning means, such as an eyebolt. The adjustment bolt is threadably attached to the adjustment brace via a non-rotatable nut. The adjustment bolt, which is disposed through the positioning means, is turned in order to adjust the position of the luminaire. As the adjustment bolt turns, the non- rotatable nut, along with the adjustment brace and optical housing attached thereto, moves along the threaded shaft of the bolt. When the turning of the bolt has ceased, the non- rotatable nut, adjustment brace and optical housing are secured in position by the frictional engagement of the thread of the bolt and the thread of the nut.
La présente invention concerne un mécanisme d'ajustement par lequel un luminaire peut être ajusté et fixé le long d'un arc. Le mécanisme d'ajustement comprend un support de fixation, une vis d'ajustement, un renfort d'ajustement qui est attaché au boîtier optique du luminaire, et un moyen de positionnement, comme un boulon à oil. Le boulon d'ajustement est vissé au renfort d'ajustement à l'aide d'un écrou non tournant. Ledit boulon d'ajustement, qui est disposé au travers des organes de positionnement, est tourné de manière à ajuster la position du luminaire. € mesure que le boulon d'ajustement tourne, l'écrou non tournant, avec le renfort d'ajustement et le boîtier optique qui y est attaché, se déplace le long de la tige filetée du boulon. Lorsque la rotation de la vis a cessé, l'écrou non tournant, le renfort d'ajustement et le boîtier optique sont maintenus en position par le frottement entre le filetage du boulon et le filetage de l'écrou.
