Abstract

A push button assembly for a cooking appliance may include a button, a button base coupled to the button defining an interior, and a button support coupled to the button and disposed within the interior. The button support may include a boss defining a channel. A support pin may be rotatably coupled with the button support. A pin may be coupled with the button base and slidably received within the channel. The push button assembly may further include a lever having a first end and second end. The lever may define an aperture configured to receive the pin.

First claim

What is claimed is:

1. A push button assembly for a cooking appliance, the push button assembly comprising:
a button;
a button base coupled to the button thereby defining an interior of the push button assembly;
a button support coupled to the button and disposed within the interior, the button support having a first boss defining a first channel and a second boss defining a second channel;
a first bearing slidably received within the first channel and a second bearing slidably received within the second channel;
a first pin and a second pin coupled with the button base, the first pin slidably received within the first bearing and the second pin slidably received within the second bearing;
a lever having a first end and second end, the lever defining an aperture therein, the aperture configured to receive the first bearing; and
an ejector pin operably coupled with the button, wherein the ejector pin is proximate to the first end of the lever and the second end of the lever is proximate to the button support, further wherein the first end of the lever is configured to displace the ejector pin upon application of a pressing force to the button.

2. The push button assembly of claim 1 , further comprising:
a button cover coupled with the button base, the button cover defining an aperture configured to receive the button.

3. The push button assembly of claim 2 , further comprising:
a support pin rotatably coupled with the button support, the support pin having an end coupled with one of the button and the button cover.

4. The push button assembly of claim 3 , wherein the one of the button and button cover further comprises a pin housing defining a slot configured to receive the end of the support pin.

5. The push button assembly of claim 2 , further comprising:
a support pin rotatably coupled with the button support, the button support having a clip configured to receive the support pin.

6. The push button assembly of claim 1 , wherein upon applying a force to the button, the button support abuts the second end of the lever thereby shifting the first end of the lever from a rest position to an eject position wherein the ejector pin is pushed outwardly.

7. A push button assembly for a cooking appliance, the push button assembly comprising:
a button;
a button base coupled to the button thereby defining an interior of the push button assembly;
a button support coupled to the button and disposed within the interior, the button support having a boss defining a channel;
a bearing slidably received within the channel;
a pin coupled with the button base, the pin slidably received within the bearing;
a lever having a first end and second end, the lever defining an aperture therein, the aperture configured to receive the bearing; and
an ejector pin operably coupled with the button, wherein the ejector pin is proximate to the first end of the lever and the second end of the lever is proximate to the button support, further wherein the first end of the lever is configured to push the ejector pin outwardly.

8. The push button assembly of claim 7 , further comprising:
a button cover coupled with the button base, the button cover defining an aperture configured to receive the button.

9. The push button assembly of claim 8 , further comprising:
a support pin rotatably coupled with the button support, the support pin having an end coupled with one of the button and the button cover.

10. The push button assembly of claim 9 , wherein the one of the button and button cover further comprises a pin housing defining a slot configured to receive the end of the support pin.

11. The push button assembly of claim 7 , further comprising:
a support pin rotatably coupled with the button support, the button support having a clip configured to receive the support pin.

12. The push button assembly of claim 7 , wherein upon applying a force to the button, the button support abuts the second end of the lever thereby shifting the first end of the lever from a rest position to an eject position wherein the ejector pin is pushed outwardly.

13. A push button assembly for a cooking appliance, the push button assembly comprising:
a button;
a button base coupled to the button thereby defining an interior of the push button assembly;
a button support coupled to the button and disposed within the interior, the button support having a boss defining a channel;
a support pin rotatably coupled with the button support;
a button base pin coupled with an interior side of the button base and slidably received within the channel; and
a lever having a first end and second end, the lever defining an aperture therein, the aperture configured to receive the button base pin.

14. The push button assembly of claim 13 , further comprising:
a button cover coupled with the button base, the button cover defining an aperture configured to receive the button.

15. The push button assembly of claim 14 , wherein the support pin further comprises an end coupled with the button cover.

16. The push button assembly of claim 15 , wherein the button cover further comprises a pin housing defining a slot configured to receive the end of the support pin.

17. The push button assembly of claim 13 , wherein the support pin further comprises a first end and a second end, the first end and the second end extending beyond the button support.

18. The push button assembly of claim 13 , wherein the button support further comprises a clip configured to receive the support pin.

19. The push button assembly of claim 13 , wherein the support pin further comprises an end coupled with the button.

20. The push button assembly of claim 13 , wherein upon applying a force to the button, the button support abuts the second end of the lever thereby shifting the first end of the lever from a rest position to an eject position.
