JPH08294402A - Boots with air conduit formed in outsole - Google Patents

Abstract

PURPOSE: To ease the extraction of boots out of the mud for the assurance of safe walking by neutralizing the sucking force due to vacuum created between the outsole and the mud by allowing air to flow through into between the outsole and the mud. CONSTITUTION: An air conduit 2 is formed running from upper or inner part of a boot 1 to the outsole of the same. A valve 3 is attached to the outsole end of the conduit 2, which valve 3 closes and prevents muddy water from flowing into the boot 1 under pressure produced when the boot 1 treads into the mud and opens and lets air in through the air conduit 2 under the suction force produced on the outsole upon the extraction of the boot 1 from the mud. The inflow of air eliminates vacuum for the prevention of suction force generation for the assurance of easy extraction of the boot 1 from the mud.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to boots in which air holes are provided from the upper part to the sole to allow air to flow into the sole.

[0002]

2. Description of the Related Art Heretofore, when walking in a muddy ground with boots, the stepped-on shoes may not come out of the mud and may not be able to move. At other times, there were cases in which only the feet would fall out while leaving boots in the mud. As a result of researching what kind of action is caused by this,
It was found that the main cause was that a vacuum was created between the shoe sole and the mud by trying to pull the shoe out of the mud, and suction force was generated.

[0003]

[Problems to be Solved by the Invention] In order to eliminate this suction force, it is necessary to eliminate the vacuum state. According to the present invention, air is introduced from the air holes into the shoe sole to eliminate the vacuum state.

[0004]

SUMMARY OF THE INVENTION According to the present invention, when the boots are to be pulled out from the mud when wearing boots and walking on mud, etc., the valve of the soles of the shoes is opened by the suction force generated by the vacuum state generated in the soles. open. Then, air flows in from the air holes to atmospheric pressure, the suction force due to the vacuum is eliminated, and the shoe can be pulled out easily. Also, when stepping on the valve, the pressure closes the valve, preventing backflow of mud or water into the air holes.

[0005]

In this way, when walking in the mud ground wearing boots, the stepped foot can be pulled out from the mud with a little force, and the walking can be facilitated.

[0006]

Embodiments of the present invention will be described below.
The effect of the air holes on the shoe sole side can be increased by arbitrarily setting the position according to the shape of the shoe sole and providing a plurality of air holes depending on the application. If the performance of the valve is improved, the backflow of water can be completely prevented, so that the shape of claim 2 is possible.

[0007]

EFFECTS OF THE INVENTION The present invention has the above-described structure, and its usage is the same as that of the conventional product, and it is easy to pull out shoes from mud or the like.
