Definitions
- the present disclosure relates generally to a telescoping light pole with an internal passage for electrical wiring and configured for a telescoping function facilitating worker access to a remote fixture.
- Lighting systems are used in many applications, with different constructions provided for different environments. Lighting is particularly important in industrial applications, which often requires work in low light conditions (e.g., at night). However, due to environmental conditions, accessing pole-mounted lights can be difficult and often dangerous. Adjustable lighting systems have been developed for industrial applications. As a result of the perils of ladder use in industrial settings, systems have been developed to safely lower the remote end (top end) of a light pole.

- an attached light fixture 122 is accessible by adjusting the pole support system height via the upper support 102 retracting into the lower support 106.
- the telescoping connection between the upper support 102 and the lower support 106 is aided by the "spring assist" from the biasing member 110.

- the locking assembly 104' further includes a raised surface 126 in the passage 1 15 opposite the translational member 1 17, implemented as a ledge (i.e., a flat surface against which the upper support 102 is held upon engaging the lock 1 16'.
- Other embodiments of lock 1 16, 1 16' may employ corresponding nuts or the like, use clasps or other fasteners, or operate using rotational versus translational motion. Any type of fastener may be used to engage the lock 1 16, 116' .

- Wiring chamber may include an adaptor 162.
- the adaptor 162 and the wiring chamber 160 (or guide member 108) may be coupled through threaded engagement.

- Wire 112 includes an elastically coiled portion 166, which is configured to conform to a length of a portion of the upper support above the locking mechanism.
- the elastically coiled portion 166 is configured such that, when the upper support 102 is lowered, the portion 166 will re-coil, thus preventing wiring 112 from bunching along the interior surface of the wiring chamber 160 (or guide member 108).
- the light fixture 122 is connected to the upper support 102.
- the illumination source of the light fixture 122 is powered through a connection to the electrical system, comprising a power source and wiring 1 12.
- the power source can be externally supplied or provided in a base, which may act as a support for the first pole.
- the wire is protected within the supports. More specifically, the wire is housed in the guide member or wiring chamber of the lower support and the interior chamber of the upper support.
- This positioning separates the wire from the spring assist system (e.g., biasing member 1 10).
- the provision of a separate housing for the wiring 1 12 is prevents the wire from interacting with or becoming damaged by the spring assist.
- the sealed conduit of the guide member or wiring chamber protects the wire from moisture, which can also be problematic.
- FIGS. 7A-7L illustrate various modes of use including wall mounting and spring mounting. As will be apparent, various means of mounting the pole support system described above will occur to those of skill in the art.
- FIG. 8 illustrates a pole support system for industrial lighting in accordance with embodiments of the present disclosure.
- Pole support system 800 comprises an upper support 806, a telescoping lower support 802 which retracts into the upper support 806 via the locking assembly. It is readily apparent that this configuration will have different associated advantages and disadvantages than the configurations above, but will operate in a similar manner by the telescoping support in conjunction with the spring assist.
