  The present invention has an excellent shock absorption function when walking, and has an excellent ventilation function for improving the ventilation characteristics by smoothly flowing fresh air from the outside into the shoe, and has a double landing function. This relates to the structure of the sole.

  Ordinary shoes are worn on a person's foot to protect the foot and at the same time facilitate movement of the person. Various types of such shoes are manufactured in order to satisfy the functional aspects required by human activities as well as improving the standard of living. For example, there are types of shoes such as athletic shoes, shoes, work shoes, boots and climbing shoes.

  Such shoes can satisfy the function according to the person's activity field and give convenience and efficiency improvement to people in the field of the activity, but only by the form that wraps the person's foot so as to seal it. Manufactured. In the surface portion of a person's foot wrapped by such shoes, the temperature increases due to friction between the inner surface of the person's foot and the shoe, and the humidity increases due to sweat generated from the person's foot. As a result, a bad odor was generated from the inside of the shoe and from the human foot, and as a result, the human foot suffered from an epigenetic disease such as athlete's foot.

  The present invention is for solving the above-described problems, and can effectively absorb a shock generated when walking to enable easy and safe walking, and air is maintained inside the shoe. The purpose of the present invention is to obtain a shoe sole structure having an excellent ventilation function and a double landing function so that a comfortable state can be maintained.

  To achieve the above object, the present invention provides a main groove that is formed on the bottom surface of the heel and communicates with the inside of the shoe to supply air, and a flat plate-type pressure pad that swells and protrudes at the bottom in a portion corresponding to the main groove. And a sole in which a connecting portion connecting the pressure pad and the sole is formed. After the bottom surface of the pressure pad touches the bottom and is pulled into the main groove, the bottom surface of the sole touches the bottom. It has a heavy landing process, and the connecting portion is formed with a thickness thinner than that of the pressure pad, and smoothly draws in the pressure pad when landing. A structure of a shoe sole having a landing function is proposed.

  The present invention can generate air naturally when walking and supply it to the inside of the shoe. The pressure pad is formed so as to protrude downward on the ground, and is formed on the pressure pad and the midsole. The internal space area between the grooves is widened, and the force applied to the midsole by the body when walking and the force applied to the pressure pad by the ground are simultaneously generated to increase the internal pressure, thereby reducing the amount of air induction. Of course, the shock absorption is increased and the comfortable and easy walking is possible.

  In addition, when walking through a double landing due to an organic action of the pressure pad and the bottom of the sole, it is possible to prevent slipping and to walk stably.

  Furthermore, the present invention may further have an excellent air induction amount and shock absorption amount by forming the pressure pad and the groove at all portions of the shoe front and the heel and communicating with each other through the flow pipe. It can be done.

FIG. 4 is a cross-sectional view of the midsole according to the present invention, FIG. 5 is a plan view showing another embodiment of the sole according to the present invention, and FIG. FIG. 7 is an exemplary diagram showing the contraction of the shoe sole according to the present invention.

  As shown in FIGS. 1 to 3, the shoe sole according to the present invention has a main groove (110) formed on the bottom surface at a portion where the heel of the foot touches and a ventilation groove (120) on the top surface of the portion where the front of the foot touches. And a midsole (100) formed with a pressure pad (210) in a corresponding portion between the main groove (110) and the midsole (100). (200).

  The main groove (110) formed in the midsole (100) is formed at a certain depth and generates air by pressure from the pressure pad (210). The ventilation groove (120) is formed in a portion of the upper surface of the midsole (100) where the front of the foot touches, and communicates with the main groove (110) to flow in air generated in the main groove (110). It is supplied to the inside of the shoe.

  Hereinafter, the communication between the main groove 110 and the ventilation groove 120 will be described in detail. The main groove (110) and the ventilation groove (120) communicate with each other through a channel pipe (130) coupled to the midsole (100). As shown in FIGS. One end of the pipe (130) is connected to the main groove (110) and the other end is connected to the ventilation groove (120) to connect the main groove (110) and the ventilation groove (120). At this time, as shown in FIG. 4, the channel pipe (130) is connected to the main groove (110) at one end and is extended in the bottom length direction of the midsole (100). A central portion of the sole (100) passes through the midsole (100) and protrudes from the upper surface of the midsole (100), and extends to the ventilation groove (120) along the upper surface length direction of the midsole (100). Extended. Therefore, all the air generated in the main groove (110) flows through the channel pipe (130) and flows into the ventilation groove (120).

  The pressure pad (210) formed on the sole (200) has a flat plate shape and is made of a rubber material to which an elastic force is applied. However, the pressure pad (210) is swollen so as to protrude from the bottom of the sole (200). When formed and landed, the entire bottom surface of the pressure pad (210) touches the bottom and draws in the direction of the main groove (110) when coming into contact with the bottom surface to induce air and absorb the impact. That is, when the pressure pad (210) which bulges and protrudes in the bottom direction is landed, the air pressure is induced by increasing the internal pressure of the main groove (110) while pulling in the direction of the main groove (110) in contact with the bottom surface. The induced air flows through the flow pipe (130) and flows into the ventilation groove (120).

  At this time, the sole (200) is formed along the frame, and a connecting portion (214) connecting the pressure pad (210) and the sole (200) is formed along the frame of the pressure pad (210). The connecting portion 214 is formed thinner than the pressure pad 210 and swells in the direction of the main groove 110. This is to allow the pressure pad (210) to be pulled in smoothly, so that the frame of the pressure pad (210) connected to the sole (200) is swollen and protruded to have a length. By being extended, the length of the frame portion can be compensated by the tension generated in the frame portion in the process of pulling in the pressure pad (210), and the pressure pad (210) can be pulled in smoothly. Is.

  On the other hand, a circular midsole protrusion (112) is formed in the main groove (110) with a bottom surface protruding and a terminal contacting the pressure pad (210), but the midsole protrusion (112) is contracted. In contact with the above while expanding, the pressure pad (210) is supported to absorb the impact. That is, when the pressure pad (210) is pulled into the main groove (110) during the landing process during walking, the midsole protrusion (112) absorbs an impact generated in the pressure pad (210) while contracting, When the pressure pad (210) protrudes outward again, the pressure pad (210) is continued and supported while expanding. At this time, the midsole protrusion 112 may be formed in a size and a form so as to have an optimum amount of shock absorption according to the size and form of the shoe to be manufactured without being limited to a circular form. is there.

  At the same time, a pad groove (212) sandwiched by the midsole protrusion (112) is formed on the upper surface of the pressure pad (210). The pad groove (212) corresponds to the midsole protrusion (112). The outer peripheral surface of the midsole protrusion (112) formed in the portion to be inserted and inserted into the portion is wrapped. Accordingly, the pressure pad (210) is pulled into the main groove (110) and the midsole protrusion (112) is contracted or the bottom direction of the pressure pad (210) protrudes to protrude the midsole protrusion (112). ) Expands, the pad groove (212) wraps around the outer peripheral surface of the midsole projection (112), preventing the midsole projection (112) from being twisted or detached, and the midsole projection (112). 112) can be improved.

  As shown in FIG. 5, an auxiliary pad 220 may be additionally formed in the corresponding portion of the auxiliary groove 140 in the sole 200. Therefore, the auxiliary pad (220) and the auxiliary groove (140) have the same effect as the organic action between the pressure pad (210) and the main groove (110), It can have improved shock absorption and air induction.

  As shown in FIGS. 6 to 7, when walking with a shoe sole having the above-described structure, when the shock absorption and air are generated and flowed, the pressure pad (210 6), the air inside the main groove (110) flows along the flow pipe (130) as shown in FIG. 6 while the entire bottom surface touches the bottom and is drawn into the main groove (110). It reaches (120) and flows into the shoe. At the same time, in the process of pulling in the pressure pad (210), at the same time, the midsole protrusion (112) supporting the pressure pad (210) gradually contracts and sufficiently absorbs the impact. It passes.

  Thereafter, when the pressure pad (210) is completely pulled into the main groove (110), the bottom surface of the pressure pad (210) and the bottom surface of the sole (200) are aligned with each other. All can be landed stably and completely through a secondary landing process where the bottom touches the bottom. The air landing amount and the shock absorption amount are increased by the double landing process through the introduction of the pressure pad (210), and a stable and easy walking can be performed while always maintaining a comfortable state. is there.
