Abstract
Embodiments of the present technology relate to safety knobs. An example automatic locking knob assembly includes a knob, a base, an adapter, and a locking sub-assembly. The locking sub-assembly is configured to automatically lock the knob into place when a valve stem of a stove is in an off position. The locking sub-assembly also allows for controlled rotation of the valve stem of the stove by actuation of buttons associated with the knob.
Claims19
An automatic locking knob assembly, comprising:
- a knob;
- a base configured to mount to a stove surface of a stove, the base comprising two pillars disposed in spaced apart relationship to one another, a first of the two pillars comprising a first groove and a second of the two pillars comprising a second groove;
- an adapter configured to mate with a valve stem of the stove extending through the base;
- and
- a locking sub-assembly, comprising:
- a first button comprising a first leg;
- a second button comprising a second leg, the first leg and the second leg being resiliently coupled to one another, the first button and the second button extending at least partially from the knob;
- the first leg and the second leg being configured to fit within one of the first groove and the second groove to place the knob in a locked position;
- and
- wherein simultaneous depression of the first and second button cause the first leg and the second leg to disassociate with the first groove and the second groove allowing the knob to freely rotate as well as the first and second legs to contact the adapter and turn the valve stem.

An automatic locking knob assembly, comprising:
- a knob;
- a base configured to mount to a stove surface of a stove, the base comprising a sidewall that comprises at least one slot;
- an adapter configured to mate with a valve stem of the stove extending through the base;
- and
- a locking sub-assembly, comprising:
- at least one button comprising at least one leg, the least one button extending at least partially from the knob;
- the least one leg being configured to mate with the at least one slot to place the knob in a locked position, wherein the knob is in the locked position the valve stem is in an off position;
- and
- wherein depression of the least one button causes the least one leg and a second leg to disassociate with the slots allowing the knob to freely rotate as well as the least one leg and the second leg to contact the adapter and turn the valve stem.

- a second button comprising a second leg, the first leg and the second leg being resiliently coupled to one another with a spring, the first button and the second button extending at least partially from the knob;
- the first leg and the second leg being configured to fit within one of the first groove and the second groove to place the knob in a locked position;
- wherein simultaneous depression of the first and second button cause the first leg and the second leg to disassociate with the first groove and the second groove allowing the knob to freely rotate as well as the first and second legs to contact the adapter and turn the valve stem;
- a first strut extending between the first button and the second button, wherein the first strut is rotationally supported on a central shaft aligned with a central axis of the assembly;
- and
- a second strut extending between the first button and the second button, wherein the second strut is rotationally supported on the central shaft, wherein simultaneous depression of the first and second buttons causes the first and second struts to rotate about the central axis.
