Abstract

Aspects of the present disclosure relate to the technological field of cooking devices, and more particularly to a cooking device that includes a surface having an opening and a gas flow control valve including a rod that extends through the opening of the surface. A knob may be arrayed on the surface to cooperate with the rod. A frame-plate may be arrayed between the knob and the surface. The frame-plate includes a central orifice that allows passage of the rod there through and is rotatable around the rod to align the frame-plate relative to the surface.

First claim

The invention claimed is:

1. A frame-plate for mounting a knob to a surface of a cooking device, the cooking device comprising at least one burner and a gas flow valve, the gas flow valve including a rod that cooperates with the knob to control the at least one burner, the frame-plate comprising:
a bottom surface surrounded by an outer wall;
a central orifice configured to allow passage of a rod of a gas flow valve through said frame-plate, wherein said frame-plate is configured to rotate about the rod;
at least one protuberance extending from the bottom surface, wherein the at least one protuberance is configured to be slotted through a corresponding opening provided in a surface of a cooking device and is configured to engage a first contact region on a rear side of said surface through an interference fit when said frame-plate is rotated about the rod; and
at least one geometry formed within the bottom surface of the frame-plate and configured to extend below the bottom surface, wherein the at least one geometry is configured to engage a second contact region on a rear side of said surface through a snap-fit connection when said frame-plate is rotated about the rod, and
wherein the frame-plate is configured to completely cover the opening in said surface when the frame-plate is mounted on the cooking device.

2. The frame-plate of claim 1 , wherein the at least one geometry is configured to provide audible feedback to indicate when the at least one geometry engages the second contact region of said surface.

3. The frame-plate of claim 1 , wherein the at least one protuberance comprises a pair of protuberances and the at least one geometry comprises a pair of geometries.

4. The frame-plate of claim 1 , wherein the at least one geometry prevents at least one of removal and displacement of said frame-plate by a user when the at least one geometry engages the second contact region of said surface.

5. The cooking device of claim 1 , further comprising:
a gap defined between the frame-plate and the surface.

6. The cooking device of claim 1 , wherein the at least one protuberance comprises two protuberances configured to pass through the opening in the surface and engage the first contact region of the surface upon rotation of the frame-plate about the rod to align the frame-plate relative to the surface.

7. The cooking device of claim 1 , wherein the at least one geometry comprises two geometries configured to engage the second contact region of the surface through a snap-fit connection upon rotation of the frame-plate about the rod.

8. The cooking device of claim 1 , wherein the at least one geometry comprises an S-shape.

9. The cooking device of claim 8 , wherein the at least one geometry is configured to provide audible feedback to indicate when the at least one geometry engages the second contact region of the surface.

10. A method of mounting a frame-plate to a surface of a cooking device, the method comprising:
providing said cooking device having at least one burner and a gas flow valve, said gas flow valve including a rod extending through an opening in said surface;
providing said frame-plate on a front side of the surface, the frame-plate having a bottom surface surrounded by an outer wall, a central orifice, at least one protuberance extending below the bottom surface, and at least one geometry formed within the bottom surface;
passing the rod through the central orifice of said frame-plate;
slotting the at least one protuberance through the opening in said surface; and
rotating said frame-plate about the rod to engage the at least one protuberance with a first contact region on a rear side of the surface and to engage the at least one geometry with a second contact region of said surface, wherein rotation of said frame-plate about the rod assembles said frame-plate relative to said first contact region through an interference fit and relative to the second contact region through a snap-fit connection, and
wherein the frame-plate is configured to completely cover the opening in the surface.

11. The method of claim 10 , further comprising:
providing said frame-plate with two geometries formed within the bottom surface and configured to engage the second contact region of said surface through a snap-fit connection.

12. The method of claim 10 , further comprising:
rotating said frame-plate about the rod until audible feedback is produced.

13. The method of claim 10 , further comprising:
providing said cooking device including said surface, wherein said cooking device is one of a hot panel or a cooktop.

14. The method of claim 10 , further comprising:
placing a knob on the rod with said frame-plate arrayed between the knob and a front side of said surface, wherein the knob is configured to cooperate with the rod to control the at least one burner.
