发明名称 Device for heating thermoplastic eyeglass frames
摘要 A device for heating a thermoplastic eyeglass frame having a rim and bridge portion and a temple portion, includes a housing having a pair of spaced infrared heat radiating surfaces mounted therein. The surfaces form an open-ended channel therebetween for receiving one of the eyeglass frame portions while permitting the other of said frame portions to remain out of range of the heat radiating surfaces. The heat radiating surfaces comprise spaced external surfaces on a heating block having a heating element embedded therein. The front radiating surface is larger than the rim and bridge portion of the frames while the rear radiating surface is smaller than the rim and bridge portion, for allowing the temple portions of the frames to extend beyond the rear radiating surface without exposure to that radiation. The rear radiating surface is small enough to fit between the temples of the smallest eyeglass frames in use but have their ends formed to radiate infrared rays in a diverging conformation to reach out and meet with the radiation of the larger front radiator, to thus accommodate radiation of and heating of any size eyeglass frames from the largest to the smallest in use. To further facilitate use of this device, support means located in front of and behind the open-ended channel support the eyeglass frames, either the rim or bridge portion, or the temple portion or any part thereof, in the chosen position for radiation by the operator of the device.
