Abstract

A trim system includes a trim housing defining a top trim housing end and a bottom trim housing end, the trim housing defining an inner trim housing surface, the inner trim housing surface defining a trim housing bore extending into the trim housing from the bottom trim housing end towards the top trim housing end, the trim housing bore defining an axis; and a trim piece defining a top trim piece end and a bottom trim piece end, the top trim piece end inserted into the trim housing bore, the trim piece including a retention clip defining a first end and a second end, the first end secured to a base of the trim piece, the second end defining at least one tooth, the at least one tooth cutting into the inner trim housing surface and axially securing the trim piece to the trim housing relative to the axis.

Claims (19)

1. A trim system comprising:

a trim housing defining a top trim housing end and a bottom trim housing end, the trim housing defining an inner trim housing surface, the inner trim housing surface defining a trim housing bore extending into the trim housing from the bottom trim housing end towards the top trim housing end, the trim housing bore defining an axis, the inner trim housing surface defining a plurality of grooves; and

a trim piece defining a top trim piece end and a bottom trim piece end, the top trim piece end inserted into the trim housing bore, the trim piece comprising a retention clip defining a first end and a second end, the first end secured to a base of the trim piece, the second end engaging a groove of the plurality of grooves and axially securing the trim piece to the trim housing relative to the axis, wherein the first end of the retention clip is secured to the base by a fastener, and the retention clip is rotatable about the fastener relative to the base about and between an engaged position and a disengaged position, and the retention clip extends radially outward from the first end to the second end relative to the axis in the engaged position, and the retention clip is angled inward relative to a radial direction of the axis in the disengaged position.

2. The trim system of claim 1 , wherein:

the second end of the retention clip defines a beveled edge; and

the beveled edge engages the groove of the plurality of grooves.

3. The trim system of claim 1 , wherein the retention clip is rotationally fixed relative to the base.

4. The trim system of claim 3 , wherein:

the base defines a base slot;

the retention clip defines a locking tab disposed at the first end; and

the locking tab is received and secured within the base slot.

5. The trim system of claim 3 , wherein:

the inner trim housing surface defines a pocket extending radially outwards from the trim housing bore relative to the axis;

the plurality of grooves are defined within the pocket; and

the pocket defines an angled pocket sidewall surface configured to disengage the second end from the plurality of grooves when the second end is engaged with the angled pocket sidewall surface.

6. The trim system of claim 1 , wherein:

the retention clip defines a secondary retention tab;

the secondary retention tab extends outwards from the retention clip proximate to the second end; and

the secondary retention tab engages another groove of the plurality of grooves.
