Hinged base for lighting pole

Claim 1

A hinged base for mounting a lighting pole to a foundation, said foundation including a plurality of upwardly projecting studs and an upwardly facing abutment portion, said hinged base comprising: a first and a second hinge plate, each having an aperture to pass a respective one of said studs, and a face on each of said plates so disposed and arranged as to face downwardly to bear against said upwardly facing abutment portion of said foundation; fastener means engageable to said studs and adapted to bear against the respective hinge plate to press the said face in abutment against said upwardly facing portion of said foundation; a hinge clevis carried by one of said hinge plates, said clevis having a pair of arms which form a channel between them, said channel having an axis, and an open and a closed side, said channel having a first channel width adjacent to the open side thereof, and a second channel width adjacent to the closed side, the second channel width being larger than the first channel width; a hinge pin carried by the other one of said hinge plates, said hinge pin having an axis, a first pin width, and a second pin width angularly spaced from the first pin width, said second pin width being greater than the first pin width, the respective first and second pin widths being no greater than the respective first and second channel widths, whereby with the first widths aligned, the pin can be placed in and passed through the part of the channel having the first channel width to the region having the second channel width, and may then be rotated so the two second widths are unaligned, thereby preventing removal of the pin from the channel, said post being attachable to one of said hinge plates, the axis of the pin being horizontal when the said widths are unaligned.
