2. Description of the Related Art Existing rubber boots, boots, etc., regardless of price, are used for snow plucking in winter, liquor storehouses, pickle factories, tofu factories, etc. that handle large amounts of water and work in frozen warehouses. For example, when you have to wear rain boots at all times, the perspiration phenomenon from your feet and the temperature difference between the inside and outside of the boots cause water droplets to accumulate inside the boots in a relatively short time, creating an extremely uncomfortable environment. Not only that, but if it is left without being fully dried after that, and if it is left undried and kept worn repeatedly, it may cause a bad smell and become a hotbed for athlete's foot and other bacteria. Therefore, in the case of boots that are more likely to get wet and hard to dry once wet, it is possible to quickly dry the sweat and condensation that tend to be trapped inside the boots. It is a major issue over to or not to those of comfort and comfort for many years, even early realization that the day had been desired.

As a technique for solving such a problem of stuffiness, for example, a plurality of independent recesses disclosed in Japanese Patent Laid-Open No. 11-276201 are formed in the lower layer of the bottom, and the plurality of recesses have hygroscopicity. However, there is an inner boot formed by forming a bridge-like upper layer that allows moisture to pass through.In the case where this inner boot is worn and boots are worn, the perspiration of the sole of the foot is certainly caused by the recesses through the upper layer of the bottom. Although it has the advantage that the upper upper part of the bottom upper part is kept comfortable, it is necessary to prepare inner boots in addition to boots, which is relatively expensive and troublesome to wear. It causes the drawback that it is not suitable for daily use. In the invention disclosed in Japanese Utility Model Laid-Open No. 7-33102, air ducts are provided at the front and rear of boots, the inside of the instep including the toes is formed into a resilient net, and the space is provided between the boot and the outer wall. It is intended to reduce the contact area with the foot by forming a gap of several mm to reduce the discomfort caused by dew condensation or sweating, but the inner wall structure of the mesh is individually contacted with the foot surface. This results in the formation of a space that is not continuous and has a drawback that good air permeability cannot be ensured.

Further, in the invention disclosed in Japanese Unexamined Patent Publication No. 8-84603, a "ventilation boot with an intake / exhaust device" is provided, which is formed by a ventilation tube provided with a vent hole extending to the front rising part of the instep part, and gripping the vent hole so as to wrap it. Has been made, but the structure with the intake and exhaust device provided on the instep is complicated, and it will be more expensive than general boots,
There is a drawback that it becomes uncomfortable in appearance, and the tubular protrusion provided on the upper surface of the shoe sole, as in Japanese Utility Model Laid-Open No. 3-53102 “Boots with ventilation in shoes”, By repeating the load and release of the user's weight, the outer surface of the boots repeatedly swells and restores, and it is also possible to automatically discharge the air in the boots and take in the outside air. The cylindrical projection on the top of the shoe sole is not suitable for firmly supporting the feet because it has a structure in which the outer surface swells and restores repeatedly due to weight bearing, and is not suitable for supporting the feet. It is not suitable for use in places where the feet are unstable and therefore lacks versatility, and for the same reason, even in the case of "boots with ventilation performance" devised by Noboru 3044249, Air pump-like air on the heel of the bottom It is a kind of thing that the air chamber is repeatedly compressed and restored by the weight load during walking to automatically ventilate, and it is not suitable for work on frozen snowy roads or high places. It is impossible to solve the difficulty of being.

As described above, although development of a technique for improving the breathability of boots has been promoted in various fields,
Some problems such as lack of general versatility, structure that is too complicated to provide at low cost, and difficult to carry out routine maintenance were left unsolved,
In this invention, from the perspective of whether it is possible to provide boots that are easy to wear on a daily basis and yet highly breathable, the development and research of the boots have been started quickly, and trial and error over a long period of time and numerous trial productions have been made. As a result of repeating experiments, the present invention finally succeeded in realizing boots having a novel structure. The configuration will be described in detail below along with an embodiment representative of the present invention shown in the drawings. I decided to.

[0006]

As can be clearly understood from the embodiments of the present invention shown in the drawings, the boots of the present invention basically have the following construction. That is, a plurality of vertical groove-shaped ventilation passages extending in the vertical direction are formed over the entire inner peripheral surface of the cylindrical body main body excluding the edge band portion having the entire predetermined lower width from the upper end. The upper end of each of the ventilation passages is in communication with a ventilation hole that penetrates the thickness direction of the tubular body body and opens to the outside, and the outsides of all the ventilation holes are

To change the expression of the boots having the above basic structure, the upper and lower parts of the tubular body main body are vertically moved from the upper end to the entire inner peripheral surface excluding the edge band having the entire predetermined lower width. In addition to forming a number of vertical groove-shaped ventilation passages extending in the same direction, the upper ends of these vertical groove-shaped ventilation passages communicate with the ventilation holes that penetrate through the thickness direction of the tubular body and open to the outside. At the same time, the outside of all the ventilation holes is made blind by a hole concealing protrusion that hangs downward from the lower edge of the outer peripheral surface of the tubular body main body edge band or slightly higher than it. By covering and hiding the structure, it is possible to prevent rainwater from entering the ventilation hole from the lateral direction or the oblique lateral direction above it, and to secure a ventilation path that is not visible from the outside. On the other hand, the lower end side of the vertical groove-like ventilation passage is empty inside the shoe part that is integrally molded below the tubular body part. It can be said to be boots configured so as to be communicated with or substantially communicating shape.

A large number of vertical groove-shaped air passages extending in the vertical direction over the circumference are formed, and the lower end sides of these vertical groove-shaped air passages communicate with or are substantially connected to the inner space of the shoe portion integrally formed below the tubular body portion. Of the tubular trunk body and the entire inner peripheral surface of the shoe section are appropriately finished with a lining material, while each upper end of the vertical groove-like ventilation passage has a tubular trunk section. The ventilation holes that penetrate through the thickness direction of the main body and open to the outside are connected to each other, and the outside of all the openings of the ventilation holes is the lower end edge of the outer peripheral surface of the tubular trunk body edge band or slightly higher. Formed in a blind structure covered blindly with a hole concealing protrusion that hangs down from the entire circumference It is possible to become one with the boots Te.

If it is shown by a more specific structure,
Along the entire inner peripheral surface of the tubular body main body excluding the edge band of the entire predetermined lower width from the upper end, a plurality of vertical groove-shaped ventilation passages extending in the vertical direction are formed and the vertical groove-shaped ventilation is performed. Finish the entire tubular body and inner surface of the shoe with an appropriate liner so that the lower end of the road is in communication with or is substantially in communication with the internal space of the shoe that is integrally molded under the tubular body.
