A cooking appliance includes an oven cavity accessed through first and second French-style doors that are connected to the appliance through a door linkage system. The door linkage system establishes a particular timing of door openings and closings to minimize potential wear of a door gasket. That is, each of the doors has an associated gasket for use in sealing the oven cavity when the doors are closed. One of the doors is provided with an annular gasket, while the other door essentially incorporates a less that fully annular, preferably 3-sided or a three-quarter gasket. With this arrangement, each of the gaskets has three sides adapted to seal against a cabinet shell portion of the appliance, while the fourth side of the first gasket is adapted to seal against an extension provided on the other door.

1. A cooking appliance comprising: a frame;an oven cavity supported, at least in part, by the frame, said oven cavity including top, bottom, rear and opposing side walls that define a frontal opening;a first door pivotally mounted relative to the frame for selectively closing, in part, the frontal opening, said first door including an inner panel portion and an outer panel portion;a second door pivotally mounted relative to the frame for selectively closing, in part, the frontal opening, said second door including an inner panel portion and an outer panel portion;a first gasket positioned on the inner panel portion of the first door, said first gasket being substantially annular, with the first gasket including opposing gasket side portions that extend about an entire periphery of the inner panel portion of the first door; anda second gasket positioned on the inner panel portion of the second door, said second gasket being substantially less than annular, with the second gasket including a plurality of gasket portions that extends only about a partial portion of a periphery of the inner panel portion of the second door. 2. The cooking appliance according to claim 1, wherein the second gasket extends about three-fourths of the periphery of the inner panel portion of the second door. 3. The cooking appliance according to claim 1, wherein the second door includes a lateral extension member, one of said opposing gasket side portions of the first gasket member being adapted to abut the lateral extension member when the first and second doors are in a closed position to completely seal about the frontal opening. 4. The cooking appliance according to claim 3, further comprising: a linkage mechanism operatively coupled to each of the first and second doors, said linkage mechanism timing movement of the first and second doors so as to unseat the one of the opposing gasket portions from the lateral extension member upon a slight opening movement of either of the first and second doors. 5. The cooking appliance according to claim 4, wherein the slight opening movement is constituted by one of the first and second doors pivoting outward approximately 3-5 degrees. 6. The cooking appliance according to claim 4, wherein the timing mechanism shifts the second door toward a closed position at a rate faster that the first door to ensure that the one of the opposing gasket portions seats upon the lateral extension member. 7. The cooking appliance according to claim 1, wherein the second gasket extends about three sides of the periphery of the inner panel portion of the second door. 8. The cooking appliance according to claim 1, wherein the second gasket has first and second ends which terminate at positions spaced from each other such that a gasket gap is established about the periphery of the inner panel portion of the second door. 9. The cooking appliance according to claim 1, wherein the second gasket has an overall length which is substantially less than an overall length of the first gasket. 10. A method of operating a closure system for a cooking appliance having French-Style doors and an oven cavity including top, bottom, rear and opposing side walls that define a frontal opening comprising: opening the closure system by: shifting one of first and second doors that extend across the frontal opening of the oven cavity from a closed position towards an open position;unseating a first gasket mounted to an inner panel of the first door from an outer peripheral edge of the frontal opening, said first gasket being substantially annular including opposing gasket portions that extend about an entire periphery of the inner panel of the first door;unseating a second gasket mounted to an inner panel of the second door from the outer peripheral edge of the frontal opening, said second gasket being substantially less than annular including a plurality of gasket portions that extends only about a partial portion of a periphery of the inner panel of the second door; andexposing the oven cavity. 11. The method of claim 10, wherein the second gasket extends about three-fourths of the periphery of the inner panel of the second door. 12. The method of claim 10, further comprising: unseating one of the opposing gasket portions of the first gasket from a lateral extension member provided on the second door as either of the first or second doors is opened. 13. The method of claim 12, wherein the one of the opposing gasket portions unseats from the lateral extension member upon a 3-5 degree movement of one of the first and second doors. 14. The method of claim 10, further comprising: establishing an opening timing for the first and second doors wherein the first door is opened faster than the second door upon movement of either of the first and second doors. 15. The method of claim 10, further comprising: closing the closure system by: shifting one of first and second doors that extend across the frontal opening of an oven cavity from the open position towards the closed position;seating the second gasket against the outer peripheral edge of the frontal opening; andseating the first gasket against the outer peripheral edge of the frontal opening. 16. The method of claim 15, further comprising: seating one of the opposing gasket portions of the first gasket upon a lateral extension member provided on the second door. 17. The method of claim 16, further comprising: establishing a closing timing for the first and second doors, said closing timing ensuring that the second door closes faster than the first door, causing the one of the opposing gasket portions of the first gasket to seal against the lateral extension member. 18. The method of claim 10, wherein the second gasket extends about three sides of the periphery of the inner panel portion of the second door. 19. The method of claim 10, wherein the second gasket has first and second ends which terminate at positions spaced from each other such that a gasket gap is established about the periphery of the inner panel portion of the second door. 20. The method of claim 10, wherein the second gasket has an overall length which is substantially less than an overall length of the first gasket.
