Abstract

Abstract A boot drying apparatus utilizes a hollow plenum chamber having a lowermost open mouth portion for resting upon a hot air discharge grill disposed in the surface of a floor of a room. The chamber supports a number of upright extending tubes, each having a snout-like portion pointed in one direction. Each of the tubes has a plurality of openings disposed along the length thereof as well as an additional opening being located at the end of the snout. A rod is carried by such that the rod is slidably affixed to the tube having the uppermost end thereof extending outwardly from the tube and having the lowermost end thereof formed into a lowermost leg of an L-shaped portion of the rod to which a plate is affixed. The plate is slidably located adjacent an opening in the plenum chamber as are a plurality of curved plates located and affixed to the rod adjacent the vertical leg portion thereof within the length of the tube. The plurality of openings of the tube are selectively covered by the plates affixed to the rod dependent upon the vertical position of the rod. A spring urges the uppermost end of the rod in an upward position such that the plates within the tube cover the opening of the tube and cover the opening inside the plenum chamber. Boots are placed selectively covering each of the tubes such that the sole of the boot is displaced in an uppermost position. The weight of the boot causes the rod to be depressed downwardly thereby uncovering the openings in the tube releasing hot air from them so as to dry out the boot. The additional opening constantly discharges warm air into the toe portion of the boot or shoe. When a shoe is placed upon a tube, the opening in the plenum chamber is similarly opened so as to cause additional warm air to enter the room facilitating drying out and carrying out the moisture laden air derived from the drying of the boot. Legs are provided in the form of sheets affixed to the exterior surface of the plenum chamber so as to provide additional vertical stability to the assembly when resting on the floor of the room.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 323 words
A boot drying apparatus comprising a plenum chamber, said plenum chamber having an open mouth portion, said plenum chamber having walls adjacent said open mouth portion thereof, said walls having a plurality of openings therein communicating to the interior of said plenum chamber, said open mouth portion of said plenum chamber located at a lower surface thereof, said plenum chamber having an upper surface, said walls being located intermediate said open mouth portion and said upper surface, said upper surface having a plurality of holes therein, a plurality of tubes, said plurality of tubes and said plurality of holes and said plurality of openings being equal in number, said plurality of tubes fixedly secured to said uppermost surface, each of said tubes having an opening at one end, said opening at said one end interlocated surrounding said holes in said upper surface, each of said tubes extending upwardly from said surface and having the longitudinal axes thereof being disposed substantially parallel to one another, each of said tubes having a plurality of openings in the walls thereof, said each of said tubes having a rod extending along the length of said tubes, means to bias the uppermost end of said rod upwardly away from said plenum chamber in an uppermost position, said plurality of openings in said each of said tubes being disposed in a closed position and said plurality of openings in said plenum chamber being disposed in a closed position when said rod is disposed in said uppermost position, said plurality of said openings in said each of said tubes being disposed in an open position when said plurality of said openings in said plenum chamber being disposed in an open position when said rod is disposed in a downward position, an additional opening in the surface of said tubes located in the uppermost region of said tubes, said additional opening being disposed open independent of the location of said rod.
Claim 2
Dependent Claim 323 words
A boot drying apparatus comprising a plenum chamber, said plenum chamber having an open mouth portion, said plenum chamber having walls adjacent said open mouth portion thereof, said walls having a plurality of openings therein communicating to the interior of said plenum chamber, said open mouth portion of said plenum chamber located at a lower surface thereof, said plenum chamber having an upper surface, said walls being located intermediate said open mouth portion and said upper surface, said upper surface having a plurality of holes therein, a plurality of tubes, said plurality of tubes and said plurality of holes and said plurality of openings being equal in number, said plurality of tubes fixedly secured to said uppermost surface, each of said tubes having an opening at one end, said opening at said one end interlocated surrounding said holes in said upper surface, each of said tubes extending upwardly from said surface and having the longitudinal axes thereof being disposed substantially parallel to one another, each of said tubes having a plurality of openings in the walls thereof, said each of said tubes having a rod extending along the length of said tubes, means to bias the uppermost end of said rod upwardly away from said plenum chamber in an uppermost position, said plurality of openings in said each of said tubes being disposed in a closed position and said plurality of openings in said plenum chamber being disposed in a closed position when said rod is disposed in said uppermost position, said plurality of said openings in said each of said tubes being disposed in an open position when said plurality of said openings in said plenum chamber being disposed in an open position when said rod is disposed in a downward position, an additional opening in the surface of said tubes located in the uppermost region of said tubes, said additional opening being disposed open independent of the location of said rod.
Claim 3
Dependent Claim 42 words
