Abstract
A hanger bar assembly for a recessed luminaire is disclosed. The hanger bar assembly includes a first hanger bar member having a first attachment structure disposed on an end thereof, and a second hanger bar member having a second attachment structure disposed on an end thereof, the second hanger bar member being adjacent to the first hanger bar member. The first and the second attachment structures each include a first wall having a first fastener aperture and a second wall having a second fastener aperture, the first and second fastener apertures being formed about a common central longitudinal axis.
Claims19
A hanger bar member, comprising:
- a rail comprising a first end and a second end;
- and
- an attachment structure disposed on the first end of the rail, wherein the attachment structure comprises:
- at least one wall;
- a fastener, wherein a guide aperture is disposed in the at least one wall for guiding the fastener;
- and
- a mounting flange integrally coupled to the bottom end of the at least one wall and extending out from the at least one wall in a substantially perpendicular direction to the at least one wall, wherein the at least one wall is disposed perpendicular to a longitudinal axis of the rail and wherein the substantially perpendicular direction is substantially parallel to the longitudinal axis of the rail, wherein an aperture slot is disposed in the mounting flange, the aperture slot allowing for lateral movement of the attachment structure.
A hanger bar member, comprising:
- a rail, the rail comprising a first end and a second end;
- and
- an attachment structure disposed on the first end, wherein the attachment structure comprises:
- at least one wall;
- a fastener, wherein a guide aperture capable of accepting the fastener is disposed in the at least one wall;
- a mounting flange integrally coupled to the bottom end of the at least one wall and extending out from the at least one wall in a substantially perpendicular direction to the at least one wall, wherein the at least one wall is disposed perpendicular to a longitudinal axis of the rail and wherein the substantially perpendicular direction is substantially parallel to the longitudinal axis of the rail, wherein an aperture is disposed in the mounting flange, the aperture providing a passageway through the mounting flange for extending a fastener therethrough;
- and
- a protruding catch extending angularly upward from the at least one wall, wherein the catch and the mounting flange extend out on opposite sides of the at least one wall.
A hanger bar member, comprising:
- a rail comprising a first end and a second end;
- and
- an attachment structure disposed on the first end of the rail, wherein the attachment structure comprises:
- at least one wall, wherein an elongated slot aperture is disposed along a mounting flange coupled to the bottom end of the at least one wall, the elongated slot aperture providing an elongated passageway through the mounting flange;
- a fastener;
- an aperture in the at least one wall capable of accepting the fastener;
- and
- an attachment tab extending upward from the top end of the at least one wall, the attachment tab comprising a fastener aperture disposed through the attachment tab, wherein the fastener aperture provides a passageway through the attachment tab.
