Insole having arch support

The present invention relates to an insole, and more particularly to an insole having a foot support that can be adjusted in height.

As the most ideal way of walking, walking on the floor from the heel to the sole of the foot to the root of the big toe is known as the "triple" walking method.

However, the conventional shoe is applied to the sole made of a flat, the weight of the weight is concentrated on the heel of the foot when walking, the impact force is transmitted to the spine, etc., causing a burden on the waist, shoulders, neck, etc. as well as causing pain The toes are deformed and the connection of the foot is not supported, so flat feet are induced, and three-time walking is not performed, and there are various problems such as increased fatigue.

In order to solve this problem, in Korean Patent No. 239854, front and rear incisions are respectively formed on the front and rear portions of the shoe sole, so that three-time walking is naturally performed, and fatigue is significantly reduced while acupressure and blood circulation. To function. In addition, in Korean Patent No. 556050, the heel is inclined in two stages to have a first ground plane and a second ground plane, and at the same time, a boundary between the front heel and the heel and the boundary of the first ground plane and the second ground plane. The surface was upwardly recessed to a predetermined depth, so that the three-time walking could be accurately performed when walking. However, in the former case, there is a problem that the arch of the foot is not supported and the rear incision reduces the area where the rear touches the ground, thereby making it impossible to balance the body. In the latter case, the arch of the foot is not supported. There is a problem.

To this end, in Korean Patent No. 851537, the foot arch support is inserted into the connection portion of the sole of the shoe, so that the user corrects the arch of the foot when walking to induce the development of the correct foot, and keep the rolling motion of the foot naturally, In order to prevent the deformation of the disease and the foot by distributing the load due to, in the shoe sole consisting of the first half, the second half and the connecting portion connecting the first half and the second half, a foot arch support is inserted into the connecting portion, the foot arch support is the inner side of the connecting portion Disclosed is a shoe sole inserted to be positioned from the end to the center. However, since the height of the foot arch support is determined, there is a problem in that it is difficult to match all the foot arches of different sizes, and the structure of the sole is complicated because the foot arch support is inserted into the sole of the shoe, there is a problem that the manufacturing cost increases accordingly.

Accordingly, it is an object of the present invention to provide an insole capable of varying the height of the foot arch support while having a foot arch support.

Another object of the present invention is to provide an insole in which air flows smoothly in the longitudinal direction of the shoe.

Still another object of the present invention is to provide an insole in which ventilation and shock absorption are efficiently performed at the same time.

The object is an insole that is fitted inside the shoe and in contact with the sole of the wearer, the insole has a foot arch portion formed corresponding to the foot arch of the foot of the wearer, the foot arch support is attached to the back of the foot arch portion, the foot arch support A screw hole is formed at the center of the screw hole, and the height adjusting screw is screwed to the screw hole, and the height adjusting screw is achieved by an insole which adjusts the height of the foot arch support by the length protruding from the screw hole.

Preferably, the insole may include a front sole and a heel protruding toward the surface in a hemispherical shape in a portion corresponding to the front sole and the heel of the wearer.

In addition, a plurality of slots connecting both ends along the longitudinal direction of the insole are formed on the front and rear surfaces, respectively, so that the air can be smoothly ventilated through the longitudinal direction.

Preferably, the foot arch support is formed in an arc shape bent in the opposite direction of the foot arch portion, the contact portion with the insole of the foot arch support may form an extension to have a wide contact area.

In addition, the support ribs protrude to a constant height at the edge of the heel portion of the insole to distribute the weight that the wearer's heel presses upon seating and to stably support the heel.

According to the above structure, simply applying the insole to the inside of the shoe, it is possible to maintain the foot arch support at an appropriate height regardless of the size of the foot arch of the wearer.

In addition, the air flow in the longitudinal direction of the shoe can be made smoothly.

In addition, it is possible to efficiently perform ventilation and shock absorption at the same time.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

1 is a cross-sectional view taken along line 2-2 ′ of FIG. 1, and FIG. 3 is a cross-sectional view taken along line 3-3 ′ of FIG. 1.

1 to 3, the insole 100 forms a single body, and a convex foot arch part 110 is formed at a portion corresponding to the foot arch. Insole 100 may be injection molded from PVC, PC, rubber, nylon or plastic material. At the edge of the heel portion of the insole 100, the support rib 132 protrudes to a certain height to distribute the weight pressed down when the heel is seated and supports the heel in a stable manner.

The thickness of the insole 100 is 1.5 mm or less is appropriate, which is usually used to fit inside the prefabricated shoes used by the insole (100) by inserting the insoles (100) based on the volume of the prefabricated shoes. This is because the wearer may not feel discomfort when considering the volume of space occupied by 100).

Preferably, the surface of the insole 100 may be adhered to the absorbent fibers or coated with an absorbent paint.

Foot arch 110 is processed to protrude to the front when the insole 100 injection molding, foot foot support 112 is attached to the back surface of the foot arch (110).

The foot arch support 112 is formed in an arch shape that is bent in the opposite direction to the foot arch portion 110, and a through screw hole 114 is formed at the center thereof. A screw groove is formed in the inner wall of the through screw hole 114, and the height adjusting screw 116 is screwed thereto. A groove 117 is formed in the exposed end of the screw 116 to fit a suitable tool therein to adjust the length of the screw 116 protruding from the screw hole 114.

Preferably, the contact portion of the foot arch support 112 with the insole 100 forms the extended portions 112a and 112b to disperse the pressing force of the foot arch through a wide contact area, so that the wearer may feel comfortable.

The foot arch support 112 may be made of plastic, rubber, or the like, and the screw hole 114 may be formed integrally with the foot arch support 112, or a metal nut may be fitted to the foot arch support body 112 by insert injection. have. In addition, the height adjusting screw 116 may be applied to a metal or plastic material.

According to this structure, when the wearer's foot arch pressing the foot arch 110, the foot arch support 112 is lowered to support the foot arch of the wearer by contacting the sole of the shoe, wherein the height adjustment screw 116 is appropriately lengthened The height of the foot arch support 112 can be adjusted based on the sole of the shoe. Therefore, the wearer can always maintain a comfortable wearing comfort by adjusting the height of the foot arch support 112 to match his foot size.

According to the present invention, preferably, the front soles 120 and the heel portions 130 that are convexly raised on the portions corresponding to the front soles and the heel of the foot arch 110 of the insole 100 are respectively. Is formed. The front sole 120 and the heel 130 may be hemispherical in size to cover the front sole and the heel as a whole.

According to this structure, the shock is absorbed during the three-time walking and the ventilation is efficiently performed by pressurization and delivery of air. That is, as mentioned above, the three-time walking is to say that walking on the floor in order from the heel to the foot, the root of the big toe to go forward, as shown in Figure 4, the heel 10 is insole 100 Pressing the heel portion 130 of the air received in the space 134 formed on the back surface of the heel portion 130 is contracted by the pressure while supporting the heel to absorb the shock and move to the foot arch portion 110 at the same time do. Subsequently, when the walking is progressed and the sole foot arch presses the foot arch part 110, the air of the foot arch part 110 moves to the front sole part 120 in the same manner, and the front sole is moved to the front sole part 120 again. When pressurized, the air of the front sole 120 escapes to the front of the insole 100. In this way, since the pumping of air is made, the ventilation on the back side of the insole 100 is made smoothly.

Here, after the air escapes from the heel portion 130, the foot arch portion 110 and the front sole portion 120, the new air is filled in these portions again.

In addition, according to the present invention, a plurality of slots 102 and 104 are formed on the front and rear surfaces, respectively, to connect both ends in the longitudinal direction so that air is smoothly ventilated through the longitudinal direction of the insole 100.

The slots 102 and 104 are approximately 1 mm in size, and air flow passages are formed through the slots 102 even though the wearer's foot covers the surface of the insole 100. In particular, the air movement consisting of the heel 130, the foot arch 110 and the front sole 120 through the slot 104 formed on the back surface of the insole 100 can be performed more smoothly.

In the above description, the embodiment of the present invention has been described, but various changes can be made at the level of those skilled in the art. For example, the screw hole may be in the form of a groove that does not penetrate the foot arch support, and the foot arch support may be formed integrally with the body constituting the insole or may be manufactured separately and attached.
