Abstract

A spring clip for attaching a radiant burner unit to a cooktop includes a retention tab having a portion extending in a first direction and a retention arm defining a lever portion projecting away from the retention tab to an end displaced from the tab in a second direction generally normal to the first direction. The retention arm further defines a resiliently deformable section facilitating movement of the lever toward and away from the retention tab. The spring clip further includes a snap tab positioned opposite the retention arm from the retention tab and resiliently deflectable toward and away from the retention tab.

First claim

What is claimed is:

1. A spring clip for attaching a radiant burner unit to a cooktop, comprising:
a retention tab having a portion extending in a first direction;
a retention arm defining a lever portion projecting away from the retention tab to an end displaced from the tab in a second direction generally normal to the first direction, the retention arm further defining a resiliently deformable section facilitating movement of the lever toward and away from the retention tab; and
a snap tab extending from the retention arm and having a first portion extending away from the retention arm in the second direction and away from the retention tab in the first direction, the snap tab having a second portion that is resiliently deflectable toward and away from the retention tab.

2. The spring clip of claim 1 , further comprising a body extending in the first direction, the retention tab coupled to the body and extending generally parallel therewith.

3. The spring clip of claim 2 , wherein the resiliently deformable section of the retention arm is joined between the body and the lever portion.

4. The spring clip of claim 2 , wherein the snap tab is positioned opposite the retention arm from the retention tab by a support arm projecting from the body.

5. The spring clip of claim 4 , wherein the support arm of the snap tab is coupled with the body by a spring loop disposed between the body and the support arm, the spring loop being resiliently expandable in a direction away from the body.

6. The spring clip of claim 2 , wherein the body, the retention tab, the retention arm, and the snap tab are of a single, unitary piece of material.

7. The spring clip of claim 1 , wherein the retention tab of the snap tab includes:
a release arm extending in a vertical direction opposite the support arm, the release arm defining the portion of the snap tab that is resiliently deflectable toward and away from the retention tab; and
first and second side arms extending from the release arm on opposite sides thereof.

8. The spring clip of claim 1 , wherein the retention arm is a first retention arm and is disposed on a first side of the snap tab, the spring clip further having a second retention arm disposed on a second side of the snap tab opposite the first side.

9. A cooktop, comprising:
a support structure defining a burner unit aperture therein and a retention aperture adjacent the burner unit aperture;
a burner unit comprising a heating element retained within a housing having a vertical side wall and a lower surface with a hole therein adjacent the side wall; and
a spring clip retaining the burner unit within the burner unit aperture and including:
a retention tab engaged with the hole in the burner unit and including a portion extending in a first direction within the housing;
a retention arm defining a lever portion projecting away from the retention tab to an end contacting the side wall of the housing, the retention arm further defining a resiliently deformable section biasing the lever against the side wall; and
a snap tab spaced apart from the housing and engaged with the retention aperture.

10. The cooktop of claim 9 , wherein the biasing of the lever against the side wall of the housing retains the snap tab within the hole of the housing.

11. The cooktop of claim 9 , wherein the spring clip further has a support arm projecting from a body and supporting the snap tab within the retention aperture.

12. The cooktop of claim 11 , wherein the support arm of the snap tab is supported by a deformable portion, a spring loop applying a compressive force between the retention tab and the retention aperture.

13. The cooktop of claim 9 , wherein the spring clip further includes a body on which the retention tab, the retention arm, and the snap tab are supported, the body defining a first stability arm extending from a first side of the body along the lower surface of the housing and a second stability arm extending from a second side of the body along the lower surface of the housing.

14. The cooktop of claim 9 , wherein the snap tab includes:
a release arm having a first end disposed within the support structure and extending through the retention aperture to a second end disposed outside of the support structure; and
first and second side arms within the support structure and extending from the release arm on opposite sides thereof.

15. A method for assembling a burner unit with a cooktop, comprising:
assembling a first spring clip with a housing of the burner unit, including aligning a retention tab of the first spring clip with a first hole in a lower surface of the housing with a retention arm of the first spring clip biased against a side wall of the housing; and
engaging a spring tab of the first spring clip with a first receiving aperture disposed in a support structure of the cooktop by vertical movement of the housing toward the support structure.

16. The method of claim 15 , wherein assembling a first spring clip with the housing of the burner unit further includes:
positioning and urging the first spring clip in a first lateral direction against a bias of the retention arm to align the retention tab of the first spring clip with the first hole; and
releasing the first spring clip such that the retention tab is engaged with the first hole and the retention arm is biased against the side wall.

17. The method of claim 15 , wherein:
assembling the first spring clip with the support structure of the cooktop further includes aligning the housing of the burner unit with an aperture in the support structure; and
engaging the spring tab with the first receiving aperture includes deflection of the spring tab in a vertical direction against a bias of the first spring clip.

18. The method of claim 17 , wherein:
assembling the spring clip with the support structure of the cooktop includes positioning a portion of the housing of the burner unit against an underside of a glass substrate of the cooktop; and
deflecting the spring tab in the vertical direction such that the bias of the spring clip retains the portion of the housing of the burner unit against the underside of the glass substrate.

19. The method of claim 15 , further including assembling a second spring clip with the housing of the burner unit, including aligning a retention tab of the second spring clip with a second hole in the lower surface of the housing with a retention arm of the second spring clip biased against the side wall of the housing.

20. The method of claim 19 , wherein the vertical movement of the housing toward the support structure further engages a spring tab of the second spring clip with a second receiving aperture disposed in the support structure.
