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.
