Abstract

Pole mounted lighting system including mounting components to mount such things as an integrated multiple cross-arm assembly to a pole, a remote ballast box to the pole, or an integrated cross-arm ballast box to the pole. The mounting structures include adjustable connection members which allow customization of fit to different size poles.

Claims

1. A mounting system for installing a structure along a length of a pole comprising:

an attachment device comprising;

a pivot bracket having a base attached at a side of the structure facing the pole, the pivot bracket having a pivot axis generally parallel with the pole when the structure is installed on the pole;

resilient members positioned on lateral opposite sides of the pivot bracket;

an elongated member pivotably connected to the pivot bracket at a pivot point and having portions extending in opposite directions transverse to the pivot axis and over the resilient members, and including a recessed portion facing the pole generally aligned with the pivot point for receiving and centering the pole in the elongated member;

a securing member attachable at opposite portions of the elongated member and extending around the pole and including adjustable cinching devices to pull the elongated member to the pole.

2. The system of claim 1 wherein the resilient member comprises a pad member.

3. The system of claim 1 wherein the resilient member comprises a spring loaded device.

4. The system of claim 1 wherein the elongated member comprises a pivoting arm with a V-shaped recess generally centered along its length near a pivot axis, the V-shaped recess being adapted to receive a portion of the perimeter of the pole.

5. The system of claim 1 wherein the securing member comprises a flexible strap, and first connections at opposite ends of the strap attachable to adjustment members which are adjustable in length to cinch the strap to the elongated member.

6. The system of claim 5 wherein the strap is stainless steel.

7. The system of claim 5 wherein the strap includes first and second generally parallel rows of apertures to allow selection of a point of attachment of the strap to the first connections.

8. The system of claim 5 wherein the mounting system includes a supplemental attachment device connected to and spaced from the attachment device along the structure.

9. The system of claim 8 wherein the supplemental attachment device includes an elongated member nonpivotably attached to the structure.

10. The system of claim 1 wherein the structure comprises a ballast box having basically a box shape with one side including a door.

11. The system of claim 10 wherein the attachment device is located towards the bottom of the ballast box and the supplemental attachment device is located near the top of the ballast box.

12. The system of claim 5 wherein the securing member comprises a flexible elongated strap having one or more rows of apertures along its length, each aperture asymmetrical in nature having a larger portion decreasing in diameter to a smaller portion in the direction of elongation of the strap.

13. The system of claim 12 wherein the flexible elongated strap connects to the first connection through openings in slightly spread apart walls having a diameter which increases from a smaller to a larger diameter, and including a two headed pin having a first head that does not fit through any portion of the asymmetrical aperture and second head including a tapered portion that fits through the larger diameter portion by camming action causes convergence of the walls when tension is placed on the strap to secure the pin in place.

14. The system of claim 5 wherein the securing member comprises a flexible elongated strap made of two pieces, at least one row of openings along the strap positioned in embossments in the strap, each end of the strap connecting to adjustable connector means, the pieces sized for the diameter of the pole and having different sized embossments so that when overlapped the pieces secured to one another by nesting the embossments of one piece into those in the other piece.
