Description

{AIR PUMPING INNERSOLE}

The present invention relates to a shoe insole, and more particularly, to a shoe insole that absorbs outside air and blows air into a shoe by a pumping action to improve a shoe hygiene.

In general, shoes such as sneakers and shoes except for sandals and slippers are not easy to sweat, and ventilation is not smooth, so odor is generated in shoes or athlete's foot or other eczema is likely to occur on the feet. Also, on a hot summer day, the temperature inside the shoe suddenly rises, increasing the fatigue and causing the sudden deterioration of the condition.

In order to solve the problem of conventional shoes which are not well ventilated as described above, shoes having a plurality of pores formed on the outer surface of the shoe so as to allow ventilation are being marketed. However, such shoes are not actively blowing in the air, There is a problem that the ventilation effect depends on the external environment in a passive manner in which the wind is naturally introduced through the pores formed in the outer shell. In addition, since such shoes are expensive or costly to process the pores, they are generally expensive, so that it is very costly to provide various kinds of shoes depending on their use. In the case of shoes with a lot of pores on the surface, there is a disadvantage that the rainwater easily penetrates on the rainy day and shoes and socks easily get wet.

On the other hand, Korean Patent No. 10-0718543, Registered Utility Model No. 20-0278132, and No. 20-0155115 have proposed shoes insole having improved breathability. However, such insole is composed of a complicated structure, and there are disadvantages such as a feeling of foreign body feeling or inconvenience when worn due to various structures, and there are problems such as deforming the structure of existing shoes in order to attach the parts, In the case of the constructed insole, when the life of some parts such as magnets is short or defective, the entire shoe must be replaced, and there is a problem that the shoe design is limited.

Disclosure of the Invention The present invention was conceived in order to solve the problems of the conventional shoe insole as described above, and it is an object of the present invention to provide a shoe insole which is excellent in ventilation function and simple in structure, easy to install and wear, It is intended to provide a shoe insole which can be used for general purposes and can be replaced only when parts are defective. It is also an object of the present invention to provide a shoe insole that can be expected to have a cushioning effect as well as a ventilation effect.

According to an aspect of the present invention, there is provided a shoe insole comprising: a base pad disposed on an inner bottom surface of a shoe and having a magnet mounted on an upper surface of a rear heel portion; A front end portion of the base pad is coupled to the base pad and a rear end portion of the base pad is configured as a free end so that the rear side is pivotable up and down, A heel pad to which a magnet having the same polarity as the magnet mounted on the upper surface is mounted; An air bladder of an elastic material having an air inlet at one side thereof. The air bladder is disposed between the base pad and the heel pad. When the heel pad is pressed downward, air is pumped into the shoe through the air inlet Means.

Here, each of the magnets mounted on the base pad and the heel pad is fitted into the concave magnet mounting groove formed on the heel top surface of the base pad and the bottom surface of the heel pad, respectively.

In the lower portion of the front end side of the backhoe pad, one coupling protrusion is protruded on both the left and right sides, and the coupling protrusion is fitted into the heel pad coupling groove formed in the base pad.

In addition, an air outlet of the air pumping means is disposed between each engaging projection of the backhoe pad, and a concave air flow groove is formed so that air can pass therethrough.

The air inlet port of the air pumping means is made of a plastic material and is fitted into the air flow grooves formed between the right and left coupling protrusions of the heel pad.

It is preferable that the portion where the engaging protrusion of the backhoe pad is formed is flat and the lower surface on the rear side of the engaging projection is configured to be thinner than the front side in order to accommodate the air pumping means.

According to the present invention as described above, ventilation can be effected by sucking outside air and blowing air into the shoe, and a pumping action and a cushioning effect can be expected by using the repulsive force of the magnet. In addition, it has a simple structure, simple installation and removal, easy replacement of parts, excellent wearing feeling, universal use for existing shoes, and also has an advantage of having a height effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the configuration and operation of a shoe insole according to the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

1 to 3, the shoe insole according to the present invention includes a base pad 10, a heel pad 20, and an air pumping means 30.

The base pad 10 is disposed on the entire inner bottom surface of the shoe so as to provide a cushion on the sole of the shoe wearer. The base pad 10 is preferably made of an elastic material such as rubber or silicone for cushioning. It is preferable that the heel portion is relatively thick and the heel portion is relatively thin.

This base pad 10 is constructed in the same manner as a general shoe insole. However, as shown in FIG. 2, a magnet 12 is mounted on a rear heel portion, A magnet mounting groove 14 for inserting and mounting the magnet 12 is formed on the upper surface of the rear portion of the body 10. In the front side of the magnet mounting groove 14, there are formed left and right heel pad connecting grooves 16 in which the engaging protrusions 22 of the heel pad 20 are inserted in order to engage the heel pad 20 to be described later .

The back padding 20 is a cushion member disposed on the upper layer of the back side heel portion of the base pad 10. The front side portion is coupled to the base pad 10 and the rear end portion is configured as a free end, As shown in Fig. In the lower part of the front end side of the backhoe pad 20, one coupling protrusion 22 protrudes from both the left and right sides, and the coupling protrusion 22 is formed on the base pad 10, And the hinge pad 20 is configured to be pivotally connected to the base pad 10 in a rearward direction with respect to the base pad 10 by being engaged with the groove 16 in an interference fit manner.

Although the coupling protrusions 22 are illustrated as being bar-like projections protruding vertically and inserted into the heel pad coupling grooves 16 of the base pad 10 in the present embodiment (even if the heel pad 20 The base pad 10 and the heel pad 20 may be hinged or bonded to each other for a more smooth turning operation.

2, it is preferable that the periphery of the coupling protrusion 22 be flattened for smooth contact with the base pad 10, and the coupling protrusions 22 of the right and left sides The air inlet 32 of the air pumping means 30 described later is disposed so that a concave air flow groove 24 is formed so that air can pass therethrough. The cross section of the air flow grooves 24 is preferably formed in a substantially rectangular shape since the periphery of the engaging projections 22 is flat.

It is preferable that the central portion of the back padding 20 is formed in a substantially concave shape or a thinner thickness than the front side in order to accommodate the air pumping means 30 described later. A magnet 26 is mounted on a lower surface of the back pad 20 at a position corresponding to the magnet 12 mounted on the base pad 10. The magnet 26 is mounted on the back pad 20, And is inserted into a magnet mounting groove 28 formed concavely in the lower side of the rear side of the magnet mounting groove 28. [

The magnets 12 mounted on the base pad 10 and the magnets 26 mounted on the heel pad 20 are arranged so as to have the same polarity, 10 and the backbone pad 20 are subjected to forces in directions opposite to each other.

The air pumping means 30 is a kind of a hand pump, and is configured in the form of an air bag of an elastic material provided with an air inlet 32 on one side. For example, the air pumping means 30 is compressed and deformed by a pressing force, such as a rubber bulb used in a pipette or the like, and then swells back when the pressing force is released. The air pumping means (30) is disposed between the base pad (10) and the heel pad (20). As described above, the air pumping means 30 is made of an elastic material such as rubber or other synthetic resin. However, the air inlet 32 may be formed in the shape of a curved surface of the heel pad 20 The plastic air inlet 32 and the heel pad 20 are preferably made of a rigid plastic material so that they can be fitted into the air flow grooves 24 formed between the left and right side engagement projections 22 in an interference fit manner. It is preferable that the air flow grooves 24 are formed so that their shapes and dimensions are correspondingly formed so that the air flow passages 32 can be firmly fitted into the air flow grooves 24. On the other hand, the air pumping means 30 may be configured to be foldable by forming a plurality of pleats such as a bellows or an accordion.

FIG. 3 is a sectional view showing a joint structure of a shoe insole according to the present invention having the above-described structure, and FIG. 4 is a view illustrating an operation state of the shoe insole.

4 (a), when the weight of the shoe wearer is not applied to the heel portion of the shoe insole according to the present invention, the magnets 12 of the base pad 10 and the magnets (not shown) of the heel pad 20 The rear side of the backhoe pad 20 is pushed upward and pivoted. At this time, the air introduced into the inside of the shoe from the outside flows into the air pumping means 30 through the air inlet 32, so that the air pumping means 30 swells. 4 (b), when the weight of the shoe wearer is loaded on the heel portion of the shoe insole, the heel pad 20 is pushed downward, and the air pumping means 30 is pushed down, The air inside the pumping means 30 is discharged to the inside of the shoe through the air inlet 32. [

Since this operation is repeatedly performed by repetition of the walking operation, the pumping operation is performed each time the shoe wearer walks, and the air is continuously blown into the shoe so that the ventilation effect is excellent. Further, the cushion effect of the base pad 10 and the heel pad 20 itself and the cushion effect of the repulsive force of the magnet are added, the buffer effect is excellent, and a key-level effect can be achieved without a separate height-level insole. Further, it has an advantage that it can be easily installed and disassembled with a relatively simple structure, and can be applied to all shoes that have been used without changing the structure of the shoe.

While the present invention has been particularly shown and described with reference to the preferred embodiments thereof, it should be understood that various changes and modifications may be made therein without departing from the spirit and scope of the appended claims. And should be construed as falling within the scope of protection of the present invention.
