Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to shoes such as short boots and rain boots.In particular, the inside of the shoe is automatically ventilated as the user walks, thereby preventing foot stuffiness. This prevents the bad odor and the occurrence of athlete's foot.

0002

[Prior Art] Such shoes have an elastic air bag arranged on the upper surface of the heel of the shoe, a front air pipe and a rear air pipe are attached to the air bag, and the front air pipe is connected to the shoe. It is known to have an opening at the inner toe part, a rear air tube opening at the outside of the shoe, and each of these air tubes being provided with a check valve that allows air to pass only forward. In this shoe, as the user walks, the air bladder repeatedly contracts due to the user's weight and restores due to its elasticity, so that air is sequentially introduced into the shoe from the outside.

0003

[Problems to be Solved by the Invention] However, in the above-mentioned conventional shoes, after the elastic air bladder is compressed by the weight of the user, it takes some time for the elastic air bag to return to its original inflated state. Therefore, there is a problem in that the shoe cannot follow the walking tempo of the user, and as a result, air cannot be sufficiently introduced into the shoe from the outside. The present invention has been made in an attempt to solve such problems.

0004

[Means for Solving the Problems] In order to solve the above problems, the present invention reliably follows the walking tempo of the user and introduces fresh air into the shoes from the outside, while also introducing dirty air inside the shoes. To provide a shoe that discharges water out of the shoe. That is, in the shoe of the present invention, the front end of the tread is pivotally attached to the upper part of the heel inside the shoe, and a spring is disposed between the rear end of the tread and the heel to constantly bias the tread upward. A connecting rod is rotatably supported in the heel part at its intermediate part in the vertical direction, one end of the connecting rod is connected to the rear end of the footboard, and a bottom plate is attached to the other end of the connecting rod. Attachment: The bottom surfaces of a pair of left and right air bags are fixed to the top surface of the bottom plate, and the top surface of each air bag is fixed to the bottom surface of the footboard. Each of these air bags can be deflated and expanded, and one air bag can be inhaled. The other air bag is used as a discharge bag, and the suction bag is equipped with a suction pipe that opens to the outside of the shoe, and the suction pipe is equipped with a check valve that only allows air to flow into the suction bag. An air supply pipe is provided from the suction bag to the discharge bag via the toe section inside the shoe, and the air supply pipe is provided with an air inlet/output hole at least near the toe section, and a check valve is provided near each bag. The check valve near the bag only allows air to flow out from the suction bag, and the check valve near the discharge bag only allows air to flow into the discharge bag. The present invention is characterized in that a discharge pipe opening in the opposite direction is attached, and the discharge pipe is provided with a check valve that only allows air to flow out from the discharge bag.

[0005]

[Operation] When the shoes of the present invention are worn while walking, fresh air is introduced into the shoes from the outside and dirty air inside the shoes is expelled to the outside of the shoes. That is, when the user's weight is first applied to the footboard of the heel, the footboard is pushed down against the force of the spring. Then, the connecting rod whose one end is connected to the rear end of the treadle rotates and the other end rises, raising the sole plate, causing the suction bag and discharge bag in the heel to contract between the tread plate and the bottom plate. Therefore, as will be described later, fresh air that has been sucked into the suction bag from the outside is sent out into the toe portion from the air inlet/outlet hole in the toe portion through the air supply pipe. On the other hand, as will be described later, the air collected in the discharge bag from inside the shoe is discharged to the outside through the discharge pipe. Next, when the user lifts his or her heel, the footplate is rotated upward by the force of the spring, causing the connecting rod to rotate in the opposite direction and lowering the sole plate. Then, the suction bag and the discharge bag fixed between the lower surface of the footboard and the upper surface of the bottom plate are forcibly expanded. Therefore, fresh air is drawn into the suction bag from the outside through the suction tube. On the other hand, dirty air inside the shoe enters the air pipe through the air inlet/outlet hole in the toe area and is sucked into the discharge bag. The above process is repeated as the user walks, and fresh air is introduced into the shoe from the outside while dirty air inside the shoe is expelled to the outside of the shoe.

Embodiments Next, embodiments of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 is the heel portion within the shoe. The front end of a footboard 2 is pivotally attached to the upper part of the heel part 1, so that the footboard 2 can rotate vertically about the front end. A spring 3 is disposed between the rear end of the footboard 2 and the heel part 1 to constantly bias the footboard 2 upward. A connecting rod 4 is pivotally supported in the heel portion 1 at its intermediate portion so as to be rotatable in the vertical direction. 5 is connecting rod 4

Effects of the Invention As explained above, in the present invention, the inhalation bag and the discharge bag are forcibly contracted and expanded by the user's body weight and the force of the spring as the user walks. The movement of the bag and the discharge bag can sufficiently follow the walking tempo of the user. Further, according to the present invention, when a user walks while wearing the shoes, not only fresh air is introduced into the shoes from the outside, but also dirty air inside the shoes is actively and automatically expelled to the outside of the shoes. Therefore, foot stuffiness caused by the shoes is reliably prevented, and bad odor and athlete's foot in the shoes are effectively prevented.
