Patent ID: 7091450

Claim:
A grip heater or a handle, comprising: a tubular insulator having a central region terminating in a base end region and a distal end region, said tubular insulator having, a first pair of helical recesses terminating in said end regions, said first pair of helical recesses being formed by a first helical groove and a second helical groove which is substantially parallel to said first helical groove, and a second pair of helical recesses terminating in said end regions, said second pair of helical recesses being formed by a third helical groove and a fourth helical groove which is substantially parallel to said third helical groove, said second pair of helical recesses being interposed between said first pair of helical recesses, and said first pair of helical recesses and said second pair of helical recesses being arranged in an overlapping relationship, a first heating element residing in said first pair of helical recesses along said central region of said tubular insulator and terminating in a first element first end and a first element second end which are located in close proximity to said base end region of said tubular insulator; means for transferring said first heating element from said first helical groove to said second helical groove in close proximity to said distal end region of said tubular insulator; a second heating element residing in said second pair of helical recesses along said central region of said tubular insulator and terminating in a second element first end and a second element second end which are located in close proximity to said base end region of said tubular insulator; and means for transferring said second heating element from said third helical groove to said fourth helical groove in close proximity to said distal end region of said tubular insulator.
