Abstract:
A combination of tall pole and cross arms for elevating a plurality of large wattage light fixtures, which is partially pre-assembled and pre-wired, then conveniently shipped, and then completely pre-assembled and pre-wired prior to erection at the location of installation of the pole in the ground, comprising:a base including a lower portion adapted for insertion and anchoring in the ground or to other supporting structure and an upper portion having an outside diameter; a hollow pole shipable in one or more sections, having a top with an upper open end and a bottom with a lower open end, which is mateably slip-fittable over at least a portion of the upper section of the base; a plurality of lighting fixtures mounted to one or more cross arms; a pole top including an elongated hollow vertical portion which is mateably slip fittable over the top of the pole, a hollow extension extending laterally from the elongated hollow vertical portion to each fixed cross arm, interior passageways in each cross arm communicating with openings at spaced apart positions in each cross arm defining attachment locations for the plurality of lighting fixtures; pre-wired cables between lighting fixtures and the hollow section, the pre-wired cables terminating in a header which is accessible through an opening in the top pole which is sealable by a removable cover member; pre-sized cables having a connection to said header and a length to extend from said header through the interior of the pole to in the vicinity of the base when the apparatus is assembled; adjustable connection mounts between the attachment locations on each cross arm and the lighting fixtures to allow pre-assembly of lighting fixtures to each cross arm and pre-aiming of lighting fixtures prior to shipping, and final pre-aiming once at the installation location; slip fit joints between any pole sections and between said pole top and the top of the pole to allow final assembly of the tall pole with the pole top and fixtures on the ground at the assembly location, with pre-wired cables extending in the hollow pole, and including a component for securing the cables in place in the pole, a component for deterring abrasion of the cables with the interior of the pole and a second header to electrically connect said cables to the header the pole top, to complete pre-wiring from the fixtures to at or near the bottom of the pole when the pole and pole top are on the ground; a ballast box with a mounting bracket; a bracket on the exterior near the bottom of the pole to allow mounting of the ballast box to the bracket on the pole when the pole is on the ground, the brackets including a receiver member on the pole means and a capture member near the top of the ballast box, to allow securement of the top end of the ballast box to the pole, the pole having an opening and a hollow connecting piece space apart from and below the receiver which mates into a receiving opening near the lower end of the ballast box; internal pre-wiring between pre-assembled electrical components in the ballast box, including multiple ballasts for the plurality of light fixtures, in the ballast box, and connectors to connect up with the cables in the pole; and a connection in the ballast box for quick connection to service lines to electrically connect the electrical circuitry of the pole to an electrical power source so that the pre-assembled tall pole can then be erected onto said base in the ground, with all light fixtures pre-assembled, pre-aimed, and pre-wired to a ballast box and electrical power source.
