This disclosure relates to a rotating engagement system for an aperture trim assembly that engages a recessed lighting fixture.
Recessed lighting fixtures include tension springs that are fixed in position with a support structure. Recessed lighting fixtures may also include a trim assembly that must be aligned to an adjustable assembly that may rotate to provide an angular focus of a light source of the recessed lighting fixture. However, tension springs fixed in position on a recessed lighting trim do not accommodate alignment of the trim assembly and the housing when supporting features on the housing are rotated. A means to accommodate the alignment of the trim assembly and the housing when the supporting features on the adjustable assembly are rotated would be beneficial.

Generally, as illustrated in
The aperture trim 200 may have a generally square exterior shape or may have a circular shape or any shape that may include a plurality of side walls 202 and a plurality of support walls 206. The side walls 202 and support walls 206 may extend in different directions from the flange surface 204. For example, the side walls 202 may extend substantially perpendicular to the flange surface 204, while the support walls 206 may extend at an acute angle to the flange surface 204 toward a top surface 213 that is defined along a perimeter of the aperture trim opening 215. The support walls 206 may also extend at an acute angle to the side walls 202. The side walls 202 may extend a portion of the distance from the flange to the top surface 213.
Both the plurality of side walls 202 and plurality of support walls 206 may be planer surfaces or alternatively may have some curvature. Further, the support walls 206 may be angled relative to the flange surface 204 to form a generally truncated pyramidal shape with the top surface 213. While exemplary embodiments show four support walls 206, the number of support walls 206 could be any number of support walls such as one support wall if circular, or three support walls, or five support walls.
As illustrated specifically in
In addition, each receiving member 214 may further have an alignment boss 230 extending from their respective receiving surfaces 222 in a generally perpendicular direction. Each alignment boss 230 may have a width generally equal to the diameter of the securing member 120. Also, each alignment boss 230 may have a height sufficient to extend through the rotatable ring 300 and the top surface 402 of the retention plate 400. As another option, each receiving member 214 may also have a respective ring supporting surface 238 that forms a surface adjacent of its respective alignment boss 230 and offset a distance toward the flange surface 204. The ring supporting surface 238 may be generally parallel to the receiving surface 222 of its respective receiving member 214. Each alignment boss 230 may be positioned between and thus separate its respective top surface 222 and its respective ring supporting surface 238.
Each alignment boss 230 may also have respective ring guide surface 246 formed on an exterior or outboard surface of each alignment boss. These ring guide surfaces 246 may be curved surfaces or alternatively, they may be planar. Furthermore, the center of the holes 280 and alignment bosses 230 may be located on concentric circles with a center point at the center of the aperture trim opening 215. Each alignment boss 230 may be formed as a separate part and installed onto the aperture trim 200, such as a pin or may be formed integrally with the aperture trim 200. Alternatively, each alignment boss 230 may be located independent from the receiving members 214 and ring supporting surfaces 238.
Each ring supporting surface 238 may be located outboard of its respective alignment boss 230. Alternatively, each ring supporting surface 238 may be located independent from the receiving members 214 and alignment bosses 230. The ring supporting surfaces 238 may be coplanar and offset a distance towards the flange surface 204 that is equal to or greater than the thickness of the rotatable ring 300 from their respective top surfaces 222 of their receiving members 214.
In addition, the aperture trim 200 may include a spring supporting surface 220. The spring supporting surface 220 may have a circular shape and may also be coplanar with a top surface 203 of the plurality of side walls 202 and also parallel to the flange surface 204. The spring supporting surface 220 may be offset a vertical distance from the ring supporting surface 238. The outside diameter of the spring supporting surface 220 may be less than the outside diameter of the rotation ring 300. The spring supporting surface 220 may support the tension springs 150, 160 as they are rotated along with the rotation ring 300 around the aperture trim opening 215 to ensure the tension springs 150, 160 do not move vertically while the rotation ring 300 is rotated.
The aperture trim 200 may further comprise a plurality of support bosses 260 that each have an engaging surface 270 that are parallel to the flange surface 204 and may be coplanar to each other. The engaging surfaces 270 may also be coplanar with the ring supporting surfaces 238. Alternatively, the engaging surfaces 270 may be offset a distance from the ring supporting surfaces 238. The support bosses 260 may be equally spaced apart from each other and also spaced equally apart from the receiving members 214. For example, in the exemplary embodiments of
The rotatable ring 300 may be located onto the aperture trim 200 by the receiving members 214. The rotatable ring 300 may have a ring surface 302. The exterior shape of the rotatable ring 300 is preferably circular, while it could have a different exterior shape.
The rotatable ring 300 may have a circular interior opening 306 defining an interior surface 308. In particular, the ring surface 302 of the rotatable ring 300 may engage the ring supporting surfaces 238 of their respective receiving members 214. Additionally or alternatively, the ring surface 302 may also communicate or contact with the engaging surfaces 270 of their respective support bosses 260.
The interior surface 308 of the rotatable ring 300 may also be in communication with at least one of the ring guide surfaces 246 of the alignment boss 230. These ring guide surfaces 246 may help to align the interior opening 306 of the rotatable ring 300 with the aperture trim opening 215. While the interior surface 308 may be in communication with at least one of the ring guide surfaces 246, the rotatable ring 300 is still free to rotate around the aperture trim 200 and along the ring supporting surfaces 238.
The rotatable ring 300 may further include a first pair of elongated slots 312 and a second pair of elongated slots 316. The first pair of elongated slots 312 may be positioned on a first side of the rotatable ring 300 such that the second pair of elongated slots 316 are mirrored from the first pair of elongated slots 312 and positioned on an opposite side. The pairs of elongated slots 312, 316 may be curved or linear. Additionally, the pairs of elongated slots 312, 316 may have a width slightly wider than the width of the wire forming the tension springs 150, 160. Further, a first elongated slot of each pair may be spaced a fixed distance from its corresponding second elongated slot. For example, the space between the first elongated slot and the second elongated slot may be at least 2 times the length of each of the elongated slots.
