Abstract (en)

[origin: CA2931712A1] A pole support system suitable for lighting fixtures. The system may include a lower support; a guide member or wiring chamber interior to the lower support; a telescoping upper support inside the lower support and axially movable between an extended position and a retracted position, the upper support being at least partially received in an annular space between the lower support and the guide member or wiring chamber; a biasing member biasing the upper support to the extended position; and a locking assembly partially surrounding the lower support at one end of the lower support. The locking assembly may include a body having a passage in which the upper support slides therethrough, and enclosing the passage at a first end while maintaining the passage in fluid communication with the interior of the lower support; and a lock configured to engage the upper support to constrain motion of the upper support.
