Cover assembly and methods
Systems and methods of installing a fixture into a material are provided. The fixture includes a body and a cover assembly that is removably coupled to the body and configured to move relative to the body once the body has been secured within the material. The cover assembly includes a movable component configured to aid removal of the cover assembly.
1. A fixture assembly comprising:
a body defining an interior; and
a cover assembly removably coupled to the body and extending above the interior, the cover assembly configured to move relative to the body and having a cover and an outer component removably coupled to the cover and configured to move with the cover, the outer component having a crumple zone that facilitates deformation of at least a portion of the outer component as the cover assembly is decoupled from the body, the outer component including an inner ring and an outer ring coupled to the inner ring, the cover including a notch, and the outer component including a tab extending radially inward from the inner ring that is configured to engage the notch to rotatably couple the cover and the outer component.
2. The fixture assembly of claim 1 , wherein the cover has a generally cylindrical shape and the inner ring and the outer ring are spaced apart from one another and coupled to one another by ribs.
3. The fixture assembly of claim 1 , wherein the crumple zone comprises a discontinuity.
4. The fixture assembly of claim 3 , wherein the discontinuity is one or more notches extending into the outer component.
5. The fixture assembly of claim 3 , wherein the discontinuity is one or more gaps in the outer component.
6. A cover assembly comprising:
a cover defining a notch;
a movable component configured to engage the cover, wherein the movable component defines a projection that extends radially outward and a crumple zone that facilitates deformation of at least a portion of the movable component in response to urging the projection toward the cover as the cover assembly is decoupled from a body; and
a ring having an inner ring and an outer ring coupled to the inner ring, wherein the projection extends from the outer ring,
wherein the movable component defines a tab extending radially inward from the inner ring that is configured to engage the notch to rotatably couple the cover and the movable component.
7. The cover assembly of claim 6 , wherein the crumple zone comprises a discontinuity formed in the outer ring.
8. The cover assembly of claim 7 , wherein a peak radial thickness of the projection is less than a radial thickness of the ring.
9. The cover assembly of claim 7 , wherein the discontinuity reduces a radial thickness of the outer ring by about one-third.
10. The cover assembly of claim 6 , wherein the projection defines a leading edge extending from the outer ring at an angle of about ten degrees relative to an adjacent outer surface of the outer ring.
11. The cover assembly of claim 6 , wherein the ring has a frustoconical outer surface.
