초록 ▼

Introducing ultraviolet (UV) light to activate a light sensitive chemical compound applied to interior portions of footwear alters the environment inside a shoe or other footwear to destroy microorganisms or inhibit their growth. Visible light can also be used to prevent further microorganism growth. Introducing forced air flow through the footwear removes dampness in and thereby deodorizes the footwear. A preferred embodiment comprises an adjustable shoe tree equipped with a UV germicidal light source and electronic safeguards that prevent appreciable leakage of UV radiation outside the shoe.

대표청구항 ▼

1. Apparatus for sanitizing human footwear having an opening in which a person's foot is inserted to put on the footwear, comprising: a light source operable to receive power from a power source and to emit radiation in a wavelength range that sanitizes the footwear by inhibiting growth of or destroying microorganisms present in an interior region of the footwear;a support for the light source to set it in a sanitization position to direct the radiation to the interior region of the footwear;a light block arranged to inhibit the radiation from harming an individual proximally located to the footwear during sanitization; andsafety switch circuitry operatively associated with the power source to interrupt delivery of power to the light source upon anticipation of escape from the footwear of an excessive amount of radiation caused by failure of the light block to inhibit the radiation or dislodgment of the light source from the sanitization position. 2. The apparatus of claim 1, in which the human footwear includes a shoe. 3. The apparatus of claim 1, further comprising a shoe tree including an extensible spine operatively connecting a forepart and a heel section, the forepart being sized to fit in the opening in the footwear and including the light source, the support for the light source, and an aperture through which the radiation can propagate for incidence on the microorganisms in the interior region. 4. The apparatus of claim 3, in which the extensible spine has an extension length and the heel section includes a handle suitable for a user to grasp to change the extension length of the extensible spine. 5. The apparatus of claim 1, in which the safety switch circuitry includes a light sensor that cooperates with the light block to operatively enable prevention of an excessive amount of the radiation from escaping the footwear. 6. The apparatus of claim 1, in which the light source emits ultraviolet (UV) light. 7. The apparatus of claim 6, in which the light source includes a light bulb. 8. The apparatus of claim 1, in which the light source emits visible light. 9. The apparatus of claim 1, in which the light source includes a light-emitting diode (LED).
