    • 2. The cooking appliance of claim 1, wherein the grate includes at least one rear corner ear portion having, at a laterally inward portion thereof, at least one cup member.
      • 3. The cooking appliance according to claim 2, further comprising: a hinge mount fixed to a portion of the cooktop and including a locating structure received in the at least one cup member provided on the grate when the grate is positioned over the at least one cooking element.
        • 4. The cooking appliance according to claim 3, wherein the hinge mount includes a main body portion from which extends the locating structure, said locating structure defining a pivot axis for the grate.
          • 5. The cooking appliance according to claim 4, wherein the cooktop includes a rim, said hinge mount being attached to the rim with a plurality of fasteners.
    • 14. The cooking appliance according to claim 1, further comprising: a lift assist unit provided on the cooktop for aiding a user in pivoting the grate relative to the cooktop.
  • 6. A cooking appliance comprising: a cooktop;at least one cooking element mounted to the cooktop;a grate including a surface portion for supporting a cooking vessel, wherein the grate is mounted to the cooktop and is configured to be separated from the cooktop by vertical lifting only when pivoted to any of at least two angles within a range of angles,wherein the grate includes at least one rear corner ear portion having, at a laterally inward portion thereof, at least one cup member; anda hinge mount fixed to a portion of the cooktop and including a locating structure received in the at least one cup member provided on the grate when the grate is positioned over the at least one cooking element,wherein the hinge mount includes a main body portion from which extends the locating structure, said locating structure defining a pivot axis for the grate and comprising a pair of projections extending in opposing directions from the main body portion of the hinge mount.
    • 7. The cooking appliance according to claim 6, wherein the grate includes a front body portion, a rear body portion and a perimeter body portion, said at least one rear corner ear portion extending beyond the rear body portion of the grate.
      • 8. The cooking appliance according to claim 7, wherein said at least one cup member includes a pair of cup members.
        • 9. The cooking appliance according to claim 8, wherein each of said pair of cup members is defined by a lower rear wall portion, an arcuate wall portion, a top wall portion and an open bottom portion for receiving a respective one of said pair of projections.
          • 10. The cooking appliance according to claim 9, wherein the grate is configured to be vertically lifted from the cooktop with the pair of projections sliding through the open bottom portions of the pair of cup members.
            • 11. The cooking appliance according to claim 10 wherein, upon pivoting of the grate through a predetermined angle, the lower rear wall portion extends below a portion of a respective said one of said pair of projections, thereby preventing the grate from being vertically lifted from the cooktop.
      • 12. The cooking appliance according to claim 7, wherein the perimeter body portion is adapted to rest upon the cooktop when the surface portion extends in a substantially horizontal plane.
        • 13. The cooking appliance according to claim 12, further comprising: positioning members provided on the perimeter body portion, with the positioning members aligning with recesses provided on a rim of the cooktop.
  • 15. A method of mounting a grate including a surface portion for supporting a cooking vessel over at least one cooking element of a cooktop of a cooking appliance, said method comprising: mounting the grate to the cooktop with the grate being initially separable from the cooktop by vertically lifting of the grate only when the grate is pivoted to any of at least two angles within a range of angles.
    • 16. The method of claim 15 wherein, upon pivoting through a predetermined angle, the grate is prevented from being lifted vertically based on at least one cup member, provided on at least one rear corner ear portion of the grate, becoming interlocked with the locating structure.
    • 17. The method of claim 15 wherein the grate is prevented from being lifted vertically by engagement of at least one cup member, provided on at least one rear corner ear portion of the grate, with a pair of projections of the locating structure.
      • 18. The method of claim 17, wherein the at least one cup member includes a pair of cup members, with each of said pair of cup members being defined by a lower rear wall portion, an arcuate wall portion, a top wall portion and an open bottom portion for receiving a respective one of said pair of projections, and wherein, after the grate is positioned over the at least one heating element, the grate can be vertically lifted from the cooktop with the pair of projections sliding through the open bottom portions of the pair of cup members.
        • 19. The method of claim 18 wherein, upon pivoting the grate through a predetermined angle, the lower rear wall portion extends below a portion of a respective said one of said pair of projections, thereby preventing the grate from being vertically lifted from the cooktop.
    • 20. The method of claim 15, further comprising: assisting in pivoting the grate relative to the at least one cooking element with a lift assist unit provided on the cooktop.
