Method and apparatus for mounting a light bar on the roof of a vehicle

A mounting for a light bar on a roof of a vehicle comprising:

• mounting brackets fastenable to said vehicle at opposite sides of said roof to provide fixed mounting brackets with respect to said roof;
• adjustable mounting brackets fastenable under said light bar at opposite ends thereof;
• a pivot coupling each of said adjustable mounting brackets in floating relationship to a different one of said fixed mounting brackets to enable pivoting of said adjustable mounting bracket about a first axis extending longitudinally along a length of the vehicle to position said light bar substantially level with respect to said roof about said first axis when said fixed mounting brackets are fastened to said roof and said adjustable mounting brackets are fastened to said light bar;
• each of said adjustable mounting brackets having an upper portion fastenable under said light bar and a lower portion mountable upon the roof of the vehicle, and said upper portion is coupled to said lower portion to tilt the light bar about a second axis extending laterally along a width of the vehicle to position said light bar substantially level with respect to said roof about said second axis;
• wherein said floating relationship of each of said adjustable mounting brackets with said different one of said fixed mounting brackets provides vertical adjustment of said adjustable mounting bracket up and down with respect to said fixed mounting bracket and rotation of said adjustable mounting bracket about said first axis with respect to said fixed mounting bracket, and said rotation is provided by a pivotal section journalled in said lower portion of said adjustable mounting bracket, said pivotal section being connected to said fixed mounting bracket via a bolt through an opening of said lower portion of said adjustable mounting bracket providing clearance for said bolt for rotation with said pivotal section and vertical displacement of said bolt with said pivotal section, and said mounting further comprising retainers encaptured in openings in said adjustable mounting bracket having clearance providing for vertical displacement of said retainers with said pivotal section journalled therein.

• wherein said floating relationship of each of said adjustable mounting brackets with said different one of said fixed mounting brackets provides vertical adjustment of said adjustable mounting bracket up and down with respect to said fixed mounting bracket and rotation of said adjustable mounting bracket about said first axis with respect to said fixed mounting bracket;
• wherein said vertical adjustment and said rotation about said first axis is enabled simultaneously;
• and
• wherein said pivot coupling each of said adjustable mounting brackets in floating relationship to a different one of said fixed mounting brackets is journalled in said adjustable mounting bracket by retainer members in which said pivot is mounted in said retainer members via one or more openings in said adjustable mounting bracket which have clearance to enable said vertical adjustment.

An apparatus for mounting for a light bar on a roof of a vehicle comprising:

• a mounting assembly at each end of a light bar having a first member fastenable to the light bar, a second member fastenable to one end of the side of the roof, and a third member mountable upon the roof of the vehicle;
• said second member being pivotally mounted to said first member for rotation about a first axis extending longitudinally along a length of the vehicle;
• said third member being mounted to said first member for tilting said first member about a second axis extending laterally along a width of the vehicle to a fixed tilt position, in which rotation about said first axis and tilt about said second axis levels the light bar on the roof notwithstanding the curvature of the roof, wherein said second member is mounted for vertical adjustment with respect to said third member to set the height of the light bar above the roof;
• and
• at each said end of the light bar a pivot coupling said third member in floating relationship with said second member which is coupled to said third member by retainer members, and said pivot is mounted in said retainer members via one or more openings in said third member which have clearance to enable said vertical adjustment.
