Abstract
Abstract A boot dryer utilizes a housing having an ingress port and an egress port and a low current consuming motor driven fan therein. A pair of flexible hoses are removably secured to the ports of the housing and extend downwardly therefrom when the housing is supported by a wire-like hook pivotably secured to the uppermost regions of the housing. The hook is extensible in length facilitating and supporting the housing depending downwardly therefrom. The free end of the flexible hoses, removably secured to the ports of the housing, are cut so as to form an angle to the longitudinal axis of the hoses. In use, the hoses are inserted into a pair of boots exposed in side by side relationship and a slow cool flow of air enters one boot and circulates upwardly through one hose and through the housing and then downwardly through the other hose, exiting outwardly from the remaining boot, thus drying the boot without cracking or deteriorating the interior of the boot. A timer may be utilized in conjunction with an on-off operating switch. Power is derived from household utility sources or a low voltage direct current supply.

Claim 1
Independent Claim
239 words
A boot dryer comprising a housing, an electrical motor operated fan, said fan being disposed within said housing, said housing having an ingress port and an egress port, said ingress port and said egress port being disposed in a common plane, a pair of hollow tubes, said pair of hollow tubes having one end of each removably coupled to said ingress port and said egress port, said pair of tubes each having the free end thereof disposed forming an acute angle to the longitudinal axes of each of said pair of tubes, said free ends defining a pair of openings communicating to the interior of said pair of tubes, said pair of openings each residing in intersecting planes, said intersecting planes intersecting at a line intermediate said longitudinal axes, each of said longitudinal axes of said pair of tubes being disposed parallel to one another and transverse to said common plane, a switch, a line cord, said switch and said line cord being disposed in a series electrical circuit with said electrical motor, a wire-like hook element, one end of said wire-like hook element pivotably secured to said housing, the other end of said wire-like hook element being disposed having a hook-like portion, said wire-like hook element being extensible in length, said intersecting planes extending upwardly and outwardly from said line and said common plane being disposed below said housing when said housing is supported by said wire-like hook.
Claim 2
Dependent Claim
239 words
A boot dryer comprising a housing, an electrical motor operated fan, said fan being disposed within said housing, said housing having an ingress port and an egress port, said ingress port and said egress port being disposed in a common plane, a pair of hollow tubes, said pair of hollow tubes having one end of each removably coupled to said ingress port and said egress port, said pair of tubes each having the free end thereof disposed forming an acute angle to the longitudinal axes of each of said pair of tubes, said free ends defining a pair of openings communicating to the interior of said pair of tubes, said pair of openings each residing in intersecting planes, said intersecting planes intersecting at a line intermediate said longitudinal axes, each of said longitudinal axes of said pair of tubes being disposed parallel to one another and transverse to said common plane, a switch, a line cord, said switch and said line cord being disposed in a series electrical circuit with said electrical motor, a wire-like hook element, one end of said wire-like hook element pivotably secured to said housing, the other end of said wire-like hook element being disposed having a hook-like portion, said wire-like hook element being extensible in length, said intersecting planes extending upwardly and outwardly from said line and said common plane being disposed below said housing when said housing is supported by said wire-like hook.
Claim 3
Dependent Claim
