Abstract

A safety knob assembly for actuating a burner is provided. The safety knob assembly includes a dial, the dial includes at least one alignment hole, an interlock disk, the interlock disk includes at least one locking pin, the at least one locking pin having an outer diameter less than then the inner diameter of the at least one alignment hole, a safety post, the safety post connected to the dial and the safety post including a locking hub, the locking hub connected to a switch post, a spring, the spring sized such that the inner diameter of the spring is larger than the outside diameter of the safety post, the spring positioned on the safety post and positioned between the dial and the locking post, wherein the at least one locking pin of the interlock disk engages the at least one alignment hole of the dial as a bottom surface of the dial approaches a top surface of the interlock disk, wherein the interlock disk engages the locking hub as a bottom surface of the interlock disk approaches the locking hub, and wherein the burner is actuated as the dial, the interlock disk, the safety post and the locking hub are positioned to rotate the switch post relative to the burner to allow the flow of energy from an energy source to the burner.

Claims (28)

1. A safety knob assembly for actuating a burner, said safety knob assembly including:

a dial; said dial including at least one alignment hole;

an interlock disk, said interlock disk including at least one locking pin, said at least one locking pin having an outer diameter less than then an inner diameter of said at least one alignment hole;

a safety post, said safety post connected to said dial and said safety post including a locking hub, said locking hub connected to a switch post;

a spring, said spring sized such that an inner diameter of said spring is larger than an outside diameter of said safety post, said spring positioned on said safety post and positioned between said dial and said locking hub;

wherein said at least one locking pin of said interlock disk engages said at least one alignment hole of said dial as a bottom surface of said dial approaches a top surface of said interlock disk;

wherein said interlock disk engages said locking hub as a bottom surface of said interlock disk approaches said locking hub; and

wherein the burner is actuated as said dial, said interlock disk, said safety post and said locking hub are positioned to rotate said switch post relative to the burner to allow the flow of energy from an energy source to the burner.

2. The safety knob assembly as recited in claim 1 , wherein said interlock disk includes at least one prong, said at least one prong sized to engage a void of said locking hub as said dial, said interlock disk, said safety post and said locking hub are positioned to rotate said switch post relative to the burner to allow the flow of energy from the energy source to the burner.

3. The safety knob assembly as recited in claim 1 , wherein said interlock disk includes at least one notch positioned at a hole of said interlock disk, said at least one notch sized and positioned to engage a tab of said locking hub as said dial, said interlock disk, said safety post and said locking hub are positioned to rotate said switch post relative to the burner to allow the flow of energy from the energy source to the burner.

4. The safety knob assembly as recited in claim 3 , wherein said interlock disk includes a locking post that extends outward from the bottom surface of said interlock disk, said locking post sized to engage a hole on a front surface of a device supporting the burner.

5. A safety knob assembly for actuating a burner, said safety knob assembly including:

a dial; said dial including at least one alignment hole;

an interlock disk, said interlock disk including at least one locking pin, said at least one locking pin having an outer diameter less than then an inner diameter of said at least one alignment hole and said interlock disk further including at least one prong;

a safety post, said safety post connected to said dial and said safety post including a locking hub, said locking hub including at least one void and said locking hub connected to a switch post;

a spring, said spring sized such that an inner diameter of said spring is larger than an outside diameter of said safety post, said spring positioned on said safety post and positioned between said dial and said locking hub;

wherein said at least one locking pin of said interlock disk engages said at least one alignment hole of said dial as a bottom surface of said dial approaches a top surface of said interlock disk;

wherein said at least one prong of said interlock disk engages said void of said locking hub as a bottom surface of said interlock disk approaches said locking hub; and

wherein the burner is actuated as said dial, said interlock disk, said safety post and said locking hub are positioned to rotate said switch post relative to the burner to allow the flow of energy from an energy source to the burner.

6. A safety knob assembly for actuating a burner, said safety knob assembly including:

a dial; said dial including at least one alignment hole;

an interlock disk, said interlock disk including at least one locking pin, said at least one locking pin having an outer diameter less than then an inner diameter of said at least one alignment hole and said interlock disk further including at least one notch;

a safety post, said safety post connected to said dial and said safety post including a locking hub, said locking hub including at least one tab and said locking hub connected to a switch post;

a spring, said spring sized such that an inner diameter of said spring is larger than an outside diameter of said safety post, said spring positioned on said safety post and positioned between said dial and said locking hub;

wherein said at least one locking pin of said interlock disk engages said at least one alignment hole of said dial as a bottom surface of said dial approaches a top surface of said interlock disk;

wherein said at least one notch of said interlock disk engages said at least one tab of said locking hub as a bottom surface of said interlock disk approaches said locking hub; and

wherein the burner is actuated as said dial, said interlock disk, said safety post and said locking hub are positioned to rotate said switch post relative to the burner to allow the flow of energy from an energy source to the burner.

7. The safety knob assembly as recited in claim 6 , wherein said interlock disk includes a locking post that extends outward from the bottom surface of said interlock disk, said locking post sized to engage a hole on a front surface of a device supporting the burner.
