Patent ID: 8002227

Claim:
A lighting fixture having a pivot and tilt apparatus for positioning said lighting fixture around vertical and horizontal axes comprising: a lighting fixture having a yoke with a central aperture; a vertical pivot body having a central annulus surrounded by an upper flange surface and also having an outwardly extending vertical pivot post, said vertical pivot body further having a lower flange surrounding a first end of said vertical pivot post; wherein said annulus has an annulus central axis which is substantially perpendicular to a central axis defined by said vertical pivot body; a horizontal pivot post extending through said central annulus of said vertical pivot body and having a circumferential groove; an index ring threadably engaging an end of said horizontal pivot post and said upper flange surface of said vertical pivot body; an index lock ring interposed between said index ring and said vertical pivot body; a locking knob threadably engaging a second end of said vertical pivot post extending through said yoke thereby tightening said yoke against said lower flange of said vertical pivot body which substantially surrounds said first end of said vertical pivot post thereby preventing rotation of said yoke about said vertical pivot post; a locking pin abutting against a surface of said yoke and through an aperture in an alignment washer and also through an aperture of said lower flange and into said central annulus of said vertical pivot body; whereby tightening said locking knob causes said locking pin to engage said circumferential groove of said horizontal pivot post thereby preventing rotation of said vertical pivot body about said horizontal pivot post.
