COUPLING WITH INTEGRAL FLUID PENETRATION BARRIER

摘要

The present disclosure provides a support coupling which provides a frangible point for a lighting fixture, and which prevents water from accumulating at the frangible point and from penetrating an inner chamber of the lighting fixture where electronic components are disposed. In certain example embodiments, the coupling accomplishes this by providing an inner wall and an outer wall, in which the inner wall has a higher grade (i.e., is taller) than the outer wall. A space between the inner wall and the outer wall receives an extension column. Water running down the sides of the extension column is collected in the space and pours out of the coupling over the shorter outer wall before the water reaches the top of the inner wall.

主权项

1. A support coupling, comprising:
a top portion comprising:
an inner cylindrical wall;an outer cylindrical wall disposed around the inner wall, wherein each of the inner cylindrical wall and the outer cylindrical wall comprises a top edge and a bottom edge; anda base extending from the bottom edge of the inner cylindrical wall to the bottom edge of the outer cylindrical wall,wherein a space is formed between the inner cylindrical wall, the outer cylindrical wall, and the base; andwherein the top edge of the inner cylindrical wall extends beyond the top edge of the outer cylindrical wall; and a bottom portion comprising a coupling feature, wherein an inner opening traverses the top portion and the bottom portion.
