Abstract
Abstract A handle for a small appliance, utensil or other body such as a coffee maker, for example, and particularly designed to be used in a microwave environment, the handle being made entirely of material which will remain cool when subjected to microwave radiation and being constructed of a ring encircling the appliance body and a gripping member fixed to the ring by a rigid inseparable joint, and a compressible member between the ring and the body which allows the handle to be applied to bodies having variations in dimensional tolerances.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
117 words
A handle structure for supporting a device comprising a ring member shaped to encircle said device, a handle member fixedly attached to said ring member, said ring member having a first connecting portion extending radially therefrom, said handle member having a second connecting portion assembled with said first connecting portion, and means for rigidly and nondetachably securing said connecting portions together in assembled relation, said first connecting portion being provided with axially extending projections of predetermined shape, and said second connecting portion being provided with axially extending projections shaped to interfit with the projections on the first connecting portion whereby said portions may be locked together by relative sliding movement of said portions in an axial direction.
Claim 2
Dependent Claim
117 words
A handle structure for supporting a device comprising a ring member shaped to encircle said device, a handle member fixedly attached to said ring member, said ring member having a first connecting portion extending radially therefrom, said handle member having a second connecting portion assembled with said first connecting portion, and means for rigidly and nondetachably securing said connecting portions together in assembled relation, said first connecting portion being provided with axially extending projections of predetermined shape, and said second connecting portion being provided with axially extending projections shaped to interfit with the projections on the first connecting portion whereby said portions may be locked together by relative sliding movement of said portions in an axial direction.
Claim 3
Dependent Claim
17 words
A handle structure as set forth in claim 1 wherein said connecting portions are fixedly bonded together.
Claim 4
Dependent Claim
29 words
A handle structure as set forth in claim 2 wherein said ring member and said handle member are made of material having a low dielectric loss at microwave frequencies.
Claim 5
Dependent Claim
27 words
A handle structure as set forth in claim 2 wherein said ring member and said handle member are made substantially entirely of material transparent to microwave radiation.
Claim 6
Dependent Claim
23 words
A handle structure as set forth in claim 2 wherein a compressible ring is disposed adjacent the inner surface of said ring member.
Claim 7
Dependent Claim
23 words
A handle structure as set forth in claim 5 wherein said ring member, handle member and compressible ring are transparent to microwave radiation.
Claim 8
Dependent Claim
92 words
A handle structure for supporting a device comprising a ring member shaped to encircle said device, and a handle member attached to said ring member, said ring member being split in the area where the handle member is attached to it to form two end portions, said end portions each having a connecting portion extending radially of the ring member, said handle member having a connecting portion shaped to interfit with the connecting portions of said ring member, and means for rigidly and undetachably securing said connecting portions together in assembled relation.
Claim 9
Dependent Claim
92 words
A handle structure for supporting a device comprising a ring member shaped to encircle said device, and a handle member attached to said ring member, said ring member being split in the area where the handle member is attached to it to form two end portions, said end portions each having a connecting portion extending radially of the ring member, said handle member having a connecting portion shaped to interfit with the connecting portions of said ring member, and means for rigidly and undetachably securing said connecting portions together in assembled relation.
Claim 10
Dependent Claim
23 words
A handle structure as set forth in claim 7 wherein a compressible ring is disposed adjacent the inner surface of said ring member.
Claim 11
Dependent Claim
33 words
A handle structure as set forth in claim 8 wherein said end portions of the ring member are movable during assembly with a handle member toward each other to compress the compressible ring.
Claim 12
Dependent Claim
51 words
A handle structure as set forth in claim 7 wherein said connecting portions on the ring member are each provided with interlocking means, and said connecting portion of the handle member is provided with interlocking means shaped to interfit with the interlocking means on the connecting portions of the ring member.
Claim 13
Dependent Claim
41 words
A handle structure as set forth in claim 10 wherein said interlocking means on said ring member comprises axially extending grooves and flanges, and the interlocking means on the handle member comprises a lipped slot in which said flanges are disposed.
Claim 14
Dependent Claim
26 words
A handle structure as set forth in claim 11 wherein the surfaces of said grooves and flanges are fixedly bonded to the surfaces of said slot.
Claim 15
Dependent Claim
27 words
A handle structure as set forth in claim 12 wherein said ring member and said handle member are of material having low dielectric loss at microwave frequencies.
Claim 16
Dependent Claim
27 words
A handle structure as set forth in claim 12 wherein said ring member and said handle member are made substantially entirely of material transparent to microwave radiation.
Claim 17
Dependent Claim
23 words
A handle structure as set forth in claim 9 wherein said ring member, handle member and compressible ring are transparent to microwave radiation.
