Cooking apparatus, comprising a support structure, a cooking vessel having an opening therein, a cover controlling access to the vessel, and cover actuation apparatus. The cover actuation apparatus pivots the cover, and optionally includes slide structure enabling the cover to slide out of full overlying relationship with the vessel opening to a partially overlying relationship, before the pivoting action occurs. Optional biasing structure biases the cover upwardly from a position overlying the vessel opening. Preferred structure combines both sliding action and pivoting action to displace the cover from over the vessel opening, and to present the cover to the opening for sealing over the cooking vessel.

A closure structure adapted and configured to cover and close a cooking apparatus, comprising: (a) a cover adapted and configured to close an opening in a cooking vessel; (b) slide structure facilitating sliding said cover in a direction transversely across such opening into a position fully overlying such opening in such cooking vessel, and away from such position fully overlying such opening in such cooking vessel wherein a first portion of said cover overlies such opening in such cooking vessel and a second different portion of said cover does not overlie such opening in such cooking vessel; and (c) pivot structure pivoting said cover about a pivot axis when said cover has been slid away from such position fully overlying such opening in such cooking vessel, said cover being comprised in a cover assembly, said cover assembly further comprising slide arms (64A, 64B) supporting said cover assembly from said slide structure and sliding into and out of said slide structure between an extended position and a retracted position. 2. A closure structure as in claim 1, further comprising biasing apparatus biasing the pivoting of said cover about the pivot axis, and wherein said biasing apparatus exerts a net lifting force on said closure structure, effective to automatically lift said cover. 3. A closure structure as in claim 2, said biasing apparatus exerting sufficient biasing force to lift said cover when said cover is out of the fully overlying relationship with the opening. 4. A closure structure as in claim 2, said biasing apparatus comprising at least one gas spring. 5. A closure structure as in claim 1, said pivot structure comprising a pivot base about which said cover is pivoted, and pivot linkage between said pivot base and said cover. 6. A closure structure as in claim 1, said cover being comprised in a cover assembly, said cover assembly further comprising cover lifting apparatus (62), and a cover support bar (82) between said cover lifting apparatus and said cover. 7. A closure structure as in claim 5, said cover being comprised in a cover assembly, said cover assembly further comprising cover lifting apparatus (62), a cover support bar (82) between said cover lifting apparatus and said cover, and slide arms ( 64A, 64B) supporting said cover assembly from said slide structure and sliding into and out of said slide structure. 8. A closure structure as in claim 1, said slide structure comprising an interface in a mechanical linkage between said pivot structure and said cover. 9. A closure structure as in claim 6, said slide structure comprising an interface in a mechanical linkage between said pivot linkage and said cover. 10. A closure structure as in claim 2 wherein said biasing apparatus, said slide structure, and a latch mechanism (98, 104) cooperate with each other such that opening such cooking vessel includes sliding said cover in a direction transversely across such opening, followed by pivoting said cover away from such opening. 11. A closure structure as in claim 2 wherein said biasing apparatus raises said cover a first distance, and then substantially matches the weight of said closure structure, including said cover such that said cover is substantially effectively weightless and can be moved up or down about the pivot axis with minimal effort. 12. Cooking apparatus, comprising: (a) a support structure; (b) a cooking vessel having an opening thereinto, said cooking vessel being supported by said support structure; (c) a cover, controlling access to said cooking vessel through the opening; and (d) cover actuation apparatus mounted to said support structure, said cover actuation apparatus comprising (i) slide structure facilitating sliding of said cover in a direction transversely across the opening into a position fully overlying the opening in the cooking vessel, and away from such fully overlying position, wherein a first portion of said cover overlies the opening in the cooking vessel and a second different portion of said cover does not overlie the opening in the cooking vessel, and (ii) pivot structure pivoting said cover about a pivot axis when said cover has been slid away from such fully overlying positions said cover being comprised in a cover assembly, said cover assembly further comprising lowering and lifting apparatus designed and configured to lower said cover into sealing engagement with said cooking vessel, and to lift said cover out of sealing engagement with said cooking vessel. 13. Cooking apparatus as in claim 12, further comprising biasing apparatus biasing the pivoting of said cover about the pivot axis, and wherein said biasing apparatus exerts a net lifting force on said closure structure, effective to automatically lift said cover. 14. Cooking apparatus as in claim 13, said biasing apparatus exerting sufficient biasing force to lift said cover and such of said cover actuation apparatus as pivots with said cover about the pivot axis, when said cover is out of the fully overlying position. 15. Cooking apparatus as in claim 13, said biasing apparatus comprising at least one gas spring. 16. Cooking apparatus as in claim 12, said pivot structure comprising a pivot base about which said cover is pivoted, and pivot linkage between said pivot base and said cover. 17. Cooking apparatus as in claim 12, said cover being comprised in a cover assembly, said cover assembly further comprising cover lifting apparatus (62), a cover support bar (82) between said cover lifting apparatus and said cover, and slide arms ( 64A, 64B) supporting said cover assembly from said slide structure, and sliding into and out of said slide structure. 18. Cooking apparatus as in claim 12, said slide structure comprising an interface in a mechanical linkage between said pivot structure and said cover. 19. Cooking apparatus as in claim 17, said slide structure comprising an interface in a mechanical linkage between said pivot structure and said cover. 20. Cooking apparatus as in claim 13 wherein said biasing apparatus, said slide structure, and a latch mechanism (98, 104) cooperate with each other such that opening said cooking vessel includes sliding said cover in a direction transversely across the opening, followed by pivoting said cover away from the opening. 21.
