Abstract
The invention provides heated gloves. A battery saver circuit applies heat with a temperature responsive pulse width modulation that changes the duty cycle at which heat is applied to the glove. The battery saver circuit is part of a battery pack which is mounted on the back of the glove. A reflective foil is contained within the glove for directing heat toward the wearer's hand.
Claims20
A garment comprising a heating element, an insulating member, a reflective foil and an outer shell, means for energizing said heating element either directly or intermittently with a duty cycle depending upon a user setting, and temperature sensitive means for changing said duty cycle to supply energy to said heater over greater percentages of the time as the sensed temperature becomes lower or over lesser percentages of the time as the sensed temperature becomes higher, said reflective foil being positioned to reflect heat from said heating element toward the person wearing the garment.
A device for heating a garment comprising a heating element, oscillator means including temperature sensitive means for changing the duty cycle of said oscillator as a function of variations of the ambient temperature, said duty cycle having drive pulses which become wider as said ambient temperature goes down, and a driver transistor controlled by said oscillator for controlling an intermittent application of energy to said heating element during time periods corresponding to said width of said drive pulses.
A glove with a heating element energized by a pulse width modulated system, temperature sensitive means for adjusting said pulse width as a function of ambient temperature, and means for applying energy directly to said heating element while inhibiting said pulse width modulating means.
A glove comprising a heating element, said heating element being a printed circuit strip line sandwiched between sheet of plastic film, said strip line being shaped and proportioned to extend over the backs of the wearer's fingers, said strip line terminating in a connector in the region of the back of the hand, a pocket formed on the back of the hand part of the glove, a battery pack removably fitted into said pocket, and a connector in said battery pack to receive the connector on said strip line, an insulating member, a reflective foil and an outer shell, means for energizing said heating element either directly or intermittently through an electronic circuit in said battery pack, said circuit comprising a temperature sensitive relaxation oscillator having an on/off cycle which sets said duty cycle, said duty cycle depending upon a suer setting, said temperature sensitive relaxation oscillator changing said duty cycle to supply energy to said heater over greater percentage of the time as the sensed temperature becomes lower or over lesser percentages of the time as the sensed temperature becomes higher, said reflecting foil being positioned to reflect heat from said heating element toward the person wearing the garment.
