Abstract

A bezel assembly for a control panel of a cooking appliance. The bezel assembly includes a body portion that extends along an axis and includes a body exterior surface and a body interior surface. The body interior surface defines a channel for accommodating components of a control knob assembly. A rim portion extends along the axis and includes a rim exterior surface and a rim interior surface. The rim interior surface defines an opening for accommodating components of the control knob assembly. A plurality of cam fingers are configured to be articulated radially outwardly for interfacing with an interior surface of the control panel.

First claim

What is claimed is:

1. A bezel assembly for a control panel of a cooking appliance, the bezel assembly comprising:
a body portion extending along an axis and including a body exterior surface and a body interior surface, the body interior surface defining a channel for accommodating components of a control knob assembly;
a rim portion extending along the axis and including a rim exterior surface and a rim interior surface, the rim interior surface defining an opening for accommodating components of the control knob assembly and insertion of the body portion;
at least one cam finger configured to be articulated radially outwardly for interfacing with an interior surface of the control panel; and
at least one actuating post defined by the body portion that is in axial alignment with the at least one cam finger upon insertion of the body portion into the opening of the rim portion.

2. The bezel assembly of claim 1 , wherein the at least one cam finger includes a plurality of cam fingers.

3. The bezel assembly of claim 2 , wherein each cam finger includes an inner cam surface facing the axis that is curved.

4. The bezel assembly of claim 3 , wherein each cam finger extends from a post member.

5. The bezel assembly of claim 4 , wherein each cam finger includes an outer cam surface opposite the inner cam surface, the inner cam surface and the outer cam surface extending from the post member to a tip.

6. The bezel assembly of claim 5 , wherein each cam finger widens from the post member towards the tip.

7. The bezel assembly of claim 6 , wherein each cam finger widens from the post member to a central region and narrows to the tip.

8. The bezel assembly of claim 5 , wherein each cam finger includes at least one ratchet tooth.

9. The bezel assembly of claim 1 , wherein the body exterior surface defines at least one track groove and the rim portion defines at least one connection projection that is insertable into the at least one track groove.

10. The bezel assembly of claim 9 , wherein the at least one track groove includes a vertical section extending along the axis and a horizontal section that is transverse to the vertical section.

11. The bezel assembly of claim 1 , wherein the at least one actuating post includes a plurality of actuating posts.

12. The bezel assembly of claim 11 , wherein the at least one cam finger includes a plurality of cam fingers equal in number to the plurality of actuating posts.

13. The bezel assembly of claim 1 , wherein the at least one actuating post includes an outer post surface that is curved.

14. A bezel assembly for a control panel of a cooking appliance, the bezel assembly comprising:
a body portion extending along an axis and including a body exterior surface and a body interior surface, the body interior surface defining a channel for accommodating components of a control knob assembly;
a rim portion extending along the axis and including a rim exterior surface and a rim interior surface, the rim interior surface defining an opening for accommodating components of the control knob assembly;
a plurality of cam fingers having an unlocked position and a locked position wherein the plurality of cam fingers are articulated radially outwardly from the unlocked position; and
a key including a plurality of actuating posts that move the plurality of cam fingers between the unlocked and locked positions.

15. The bezel assembly of claim 14 , wherein the plurality of cam fingers each include an inner cam surface that is curved for interfacing with one of the plurality of actuating posts.

16. The bezel assembly of claim 15 , wherein the plurality of cam fingers each extend from a post member to a tip and wherein the plurality of cam fingers each include an inner cam surface facing the axis that is curved.

17. The bezel assembly of claim 16 , wherein each post member includes a catch detent extending towards an adjacent post member to interlock the tip in the locked position.

18. A bezel assembly for a control panel of a cooking appliance, the bezel assembly comprising:
a body portion extending along an axis and including a body exterior surface and a body interior surface, the body interior surface defining a channel for accommodating components of a control knob assembly;
a rim portion extending along the axis and including a rim exterior surface and a rim interior surface, the rim interior surface defining an opening for accommodating the body portion;
the rim portion including a plurality of cam fingers having an unlocked position and a locked position wherein the plurality of cam fingers are articulated radially outwardly from the unlocked position;
the body portion including a plurality of actuating posts that move the plurality of cam fingers between the unlocked and locked positions with relative rotation between the body portion and the rim portion; and
wherein the plurality of cam fingers include elastic memory towards the unlocked position.
