Abstract
A coupling for connection of a valve and a control element in a gas cooking appliance is provided. More particularly, the present invention provides a flexible coupling to connect between a control element manipulated by the user and a gas valve that regulates the flow of fuel to a gas burner. By coupling the control and valve by a flexible coupling, options are created for the relative placement of the valve and control, which increases the space available in the interior of the appliance and can increase the space available upon its control panel.
Claims17
A cooking appliance, comprising:
- a gas burner for supplying heat to a food for cooking;
- a valve for setting a user-selected flow rate of gas to the gas burner;
- a control for allowing a user of the appliance to adjust said valve to selectively change the user-selected flow rate of gas to the burner, said control positioned in the appliance separately from said valve;
- and
- a coupling that connects said valve and said control, said coupling comprising a flexible element coupled to said valve and said control to transmit adjustments of said control by the user to said valve so as to cause said valve to change the user-selected flow rate of gas to said gas burner;
- wherein said control comprises:
- a handle portion;
- an upper cam configured to push and turn rotation by the user, said upper cam defining a locking tab;
- said upper cam in mechanical communication with said handle portion;
- an upper hub defining an opening for the receipt of said upper cam, said upper hub also defining a notch for the receipt of said locking tab;
- a lower cam configured for selective receipt of said upper cam, said lower cam connected with said flexible element;
- and
- a lower hub defining an opening for receipt of said lower cam.

A system for controlling a gas flow in a cooking appliance, the cooking appliance having at least one gas burner, the system comprising:
- a valve for setting a user-selected flow rate of gas to the gas burner;
- a control for allowing a user of the appliance to adjust said valve to selectively change the user-selected flow rate of gas to the burner, said control positioned in the appliance separately from said valve;
- and
- a coupling that connects said valve and said control, said coupling comprising a flexible element coupled to said valve and said control to communicate adjustments of said control by the user to said valve so as to cause said valve to change the user-selected flow rate of gas to said gas burner due to the adjustments;
- wherein said control comprises
- a knob;
- an upper cam configured for push and turn rotation by the user, said upper cam defining a locking tab;
- said upper cam attached to said knob;
- an upper hub defining and opening for the receipt of said upper cam, said upper hub also defining a notch for the receipt of said locking tab;
- a lower cam configured for selective receipt of said upper cam, said lower cam connected with said flexible element;
- and
- a lower hub defining an opening for receipt of said lower cam.
