Abstract:
The present invention provides a staple for a heating unit. In one embodiment, the heating unit has a base, a first insulation layer, a second insulation layer, and a heating element. The first insulation layer has a top surface and a bottom surface. The heating element rests on the top surface of the first insulation layer. The staple includes a base and a plurality of legs. The base is capable of straddling a portion of the heating element. At least one of the plurality of legs is capable of extending through the top and bottom surfaces of the first insulation layer. A portion of the leg extending through the bottom surface of the first insulation layer is capable of being rolled to form a foot. The second insulation layer is located between the bottom surface of the first insulation layer and the base. In another embodiment, the present invention includes a staple for a heating unit having an insulation layer and a heating element. The heating element rests on the top surface of the insulation layer. The staple includes a base, a leg and a barb. The base is capable of straddling a portion of the heating element. The leg extends from the base and the barb is attached to the extended leg. The barb and a portion of the extended leg are capable of extending through the top surface of the insulation layer and retaining the heating element on the top surface of the insulation layer during repeated temperature cycles of the heating element.
