Apparatus for securing a trim frame to a recessed housing member and a method of making thereof
View Patent ↗An apparatus is provided for securing a trim frame to a housing member in a recessed lighting fixture. The apparatus includes a spring associated with the trim frame having a top edge, a left edge, a right edge, and a bottom edge, a left portion, a right portion, and a center portion between the left portion and the right portion. The left portion is connected to the center portion along a first bend, and the right portion is connected to the center portion along a second bend. The left portion includes a first lead-in portion formed by a third bend and a first retention portion formed by a fourth bend, and the right portion includes a second lead-in portion formed by a fifth bend and a second retention portion formed by a sixth bend.
1. An apparatus for securing a trim frame to a housing member, both the trim frame and the housing member being parts of a recessed lighting fixture, comprising:
a spring having a top edge, a left edge, a right edge, a bottom edge, a left portion, a right portion, and a center portion between the left portion and the right portion,
wherein
the left portion is connected to the center portion along a first bend extending substantially parallel to a vertical centerline of the spring from the top edge to the bottom edge,
the right portion is connected to the center portion along a second bend extending substantially parallel to the vertical centerline of the spring from the top edge to the bottom edge,
the left portion has first lead-in portion formed by a third bend extending from the top edge to the left edge and a first retention portion formed by a fourth bend extending from the bottom edge to the left edge,
the right portion has a second lead-in portion formed by a fifth bend extending from the top edge to the right edge and a second retention portion formed by a sixth bend extending from the bottom edge to the right edge, and
the spring, which is detachably affixed to the trim frame via the center portion, is received by the housing member to secure the trim frame to the housing member.
2. The apparatus of claim 1 wherein the center portion includes at least one mounting hole.
3. The apparatus of claim 2 wherein the center portion includes two mounting holes.
4. The apparatus of claim 1 wherein the left portion and the center portion form an angle of approximately 31 degrees.
5. The apparatus of claim 4 wherein the right portion and the center portion form an angle of approximately 31 degrees.
6. The apparatus of claim 5 wherein the first lead-in portion forms an angle of approximately 80 degrees with a portion of the left portion.
7. The apparatus of claim 6 the first retention portion forms an angle of approximately 30 degrees with a portion of the left portion.
8. The apparatus of claim 7 wherein the second lead-in portion forms an angle of approximately 80 degrees with a portion of the right portion.
9. The apparatus of claim 8 wherein the second retention portion forms an angle of approximately 30 degrees with a portion of the right portion.
10. The apparatus of claim 9 wherein the housing member includes an indented surface along the interior surface of the housing member, the indented surface being positioned within the housing member such that at least a part of the first and second retention portions of the spring are located above the indented surface when the spring is received in the housing member.
11. The apparatus of claim 1 ,
wherein the spring is martempered and marquenched.
12. The apparatus of claim 11 wherein the spring is martempered and marquenched to a range of approximately 53 to 55 Rockwell C.
13. The apparatus of claim 1 wherein the spring has a first surface and a second surface, and the thickness of the spring between the first surface and the second surface is approximately 0.008 inches.
