Abstract

A multi-part cooking grate with a lower sub-grate with a first plurality of V-shaped cooking members running along a length of the lower sub-grate and having a first predetermined spacing between the first plurality cooking members along a width of the lower sub-grate, and an upper sub-grate with a second plurality of V-shaped cooking members running along a length of the lower sub-grate and having a second predetermined spacing between the second plurality of cooking members along a width of the upper sub-grate.

First claim

What is claimed is:

1. A multipart cooking grate comprising:
a lower sub-grate with a first plurality of V-shaped cooking members running along a length of the lower sub-grate and having a first predetermined spacing between the first plurality cooking members along a width of the lower sub-grate; and
an upper sub-grate with a second plurality of V-shaped cooking members running along a length of the lower sub-grate and having a second predetermined spacing between the second plurality of cooking members along a width of the upper sub-grate;
wherein the first predetermined spacing accommodates a width of each of the second plurality of cooking members and the second predetermined spacing accommodates a width of each of the first plurality of cooking members such that the upper and lower sub-grates may be nested to create a first cooking surface comprising the first and second plurality of cooking members in an interfitted alternating relationship; and
wherein the upper and lower sub-grates provide second and third cooking surfaces, respectively with a higher degree of convective heating than the first cooking surface, and;
wherein the first and second predetermined spacing differs such that the second and third cooking surfaces provide a different degree of convective heating compared to one another.

2. The grate of claim 1 , wherein the upper and lower sub-grates each have at least one upper and lower cross member, respectively, that retains the respective cooking members in the first and second predetermined spacing.

3. The grate of claim 2 , wherein the upper and lower cross members nest to prevent movement between the upper and lower sub-grates along a length.

4. The grate of claim 1 , wherein the upper and lower sub-grates each have a plurality of upper and lower cross members, respectively, and the first plurality of lower cooking members are interrupted at a location spaced apart from the ends to accommodate at least one of the plurality of upper cross members when the upper sub-grate is placed upon the lower sub-grate.

5. A multi-part cooking grate comprising:
a first upper sub-grate having a first plurality of cooking members retained in a fixed relationship relative to one another by first and second upper cross-members that receive opposite ends of the first plurality of cooking members to form end caps thereon; and
a second lower sub-grate having a second plurality of cooking members retained in a fixed relationship relative to one another by first and second lower cross members that receive opposite ends of the second plurality of cooking members;
wherein the first and second sub-grates are configured to fit together such that their respective cooking members interfit to define a first cooking surface;
wherein the first and second sub-grates each define a second and third cooking surface, respectively, when detached from one another;
wherein the first cooking surface heats with a higher degree of radiant heating than both the second and third cooking surfaces, and both the second and third cooking surfaces heat with a higher degree of convective heating than the first cooking surface;
wherein the first sub-grate retains its associated cooking members at a first predetermined spacing from one another;
wherein the second sub-grate retains its associated cooking members at a second predetermined spacing from one another; and
and the first and second predetermined spacings are different so as to provide different degrees of heating with radiant and convective heating.

6. The grate of claim 5 , wherein the lower end caps nest within the upper end caps when the first and second sub-grates are fitted together.

7. The grate of claim 6 , wherein the respective cooking members are retained in a fixed relationship with the respective end caps such that the end caps prevent movement between the first plurality of cooking members and the second plurality of cooking members along a length thereof.

8. A multi-part cooking grate comprising:
a first upper sub-grate having a first plurality of cooking members retained in a fixed relationship relative to one another by first and second upper cross-members that receive opposite ends of the first plurality of cooking members to form end caps thereon; and
a second lower sub-grate having a second plurality of cooking members retained in a fixed relationship relative to one another by first and second lower cross members that receive opposite ends of the second plurality of cooking members;
wherein the first and second sub-grates are configured to fit together such that their respective cooking members interfit to define a first cooking surface;
wherein the first and second sub-grates each define a second and third cooking surface, respectively, when detached from one another;
wherein the first cooking surface heats with a higher degree of radiant heating than both the second and third cooking surfaces, and both the second and third cooking surfaces heat with a higher degree of convective heating than the first cooking surface; and
wherein the cooking members of the lower sub-grate are interrupted to receive a third cross member of the upper sub-grate that is spaced apart from the first and second cross members of the upper sub-grate when the upper sub-grate rests upon the lower sub-grate.

9. A multi-part cooking grate comprising:
a first upper sub-grate having a first plurality of cooking members retained in a fixed relationship relative to one another by upper channelized cross-members capping ends of the first plurality of cooking members such that the ends of the first plurality of cooking members do not extend beyond the upper channelized cross members; and
a second lower sub-grate having a plurality of second cooking members retained in a fixed relationship relative to one another by lower channelized cross members capping ends of the second plurality of cooking members such that the second plurality of cooking members do not extend beyond the lower channelized cross members;
wherein the first and second sub-grates are configured to fit together such that their respective cooking members interfit to define a first cooking surface
wherein the first and second sub-grate define second and third cooking surfaces, respectively;
wherein the first cooking surface heats with a higher degree of radiant heating than the second and third cooking surface and the second and third cooking surfaces heat with a higher degree of convective heating that the first cooking surface;
wherein the lower cross members of the lower sub-grate nest within the upper cross members of the upper sub-grate when the upper and lower sub-grate are interfitted; and
wherein the upper cross members of the upper sub-grate have cooperating recesses to fit the first plurality of cooking members of the lower sub-grate when nested with the lower cross members of the lower sub-grate.

10. The grate of claim 9 , wherein the first and second plurality of cooking members of the first and second sub-grates are inverted V-shaped cooking members.

11. The grate of claim 9 , wherein the first plurality of cooking members of the upper sub-grate are V-shaped and have ends with a portion removed to be sized to fit into holes defined in the upper cross member.

12. The grate of claim 9 , wherein the second plurality of cooking members of the lower sub-grate are V-shaped and have ends with a portion removed to be sized to fit into holes defined in the lower cross member.

13. The grate of claim 9 , wherein a spacing between the cooking members of the upper sub-grate differs from a spacing between the cooking members of the lower sub-grate so as to cr
