Abstract
An air supply device of a wheel-mounted shoe which can supply ambient air into the interior of the shoe by continuously suck the ambient air in by use of the rotating force of the frictional roller interposed between adjacent ones of the wheels rotatably mounted to the bracket of the outer sole of the shoe, irrespective of the rotating direction of the wheels. Accordingly, the air supply device eliminates uncomfortableness caused by sweat and odor generated from the user in the interior of the shoe, to maintain the interior of the shoe in a pleasant state, thereby helping the user's foot health.
Claims24
An air supply device of a wheel-mounted shoe comprising:
- a fixed plate mounted to a lower surface of a top plate portion of a bracket fixed to an outer sole of the wheel-mounted shoe by fixing members;
- a housing coupled to the fixed plate such that the housing is vertically movable while being elastically supported by an elastic member;
- a frictional roller rotatably coupled to the housing by a shaft such that the frictional roller is in close contact with a circumferential surface of at least one of wheels rotatably mounted to the bracket;
- air sucking means to suck ambient air in when the frictional roller rotates;
- and
- air ventilation means to supply the air sucked in by the air sucking means into the interior of the shoe.
An air supply device of a wheel-mounted shoe comprising:
- a fixed plate mounted to a lower surface of a top plate portion of a bracket fixed to an outer sole of the wheel-mounted shoe by fixing members, and provided with a pair of guide rods respectively mounted with springs;
- a moving plate elastically mounted to the fixed plate in a state of being fitted around the guide rods such that the moving plate is vertically movable, the moving plate being provided with a freely-rotatable hollow shaft mounted to a lower portion of the moving plate;
- a frictional roller fixedly mounted on the shaft such that the frictional roller is in close contact with a circumferential surface of at least one of wheels rotatably mounted to the bracket;
- air sucking means to suck ambient air in when the frictional roller rotates;
- and
- air ventilation means to supply the air sucked in by the air sucking means into the interior of the shoe through the shaft.
