Description

Functional insole and Shoes using the same}

The present invention relates to a functional insole and a shoe to which the same is applied.

In general, the shoe serves to mitigate the impact force transmitted by the weight when walking to the spine or the like.

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. However, there was a problem that the arch of the foot (footbow) is not supported and the rear incision causes the area of the back to reach the ground to be small, thus preventing the balance of the body.

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, the bottom surface is defined by a boundary between the front heel and the heel and a boundary between the first ground plane and the second ground plane. In order to be inclined upward, the three-time walking was performed accurately while walking, but the arch of the foot was not supported.

In order to solve these problems, in Korean Patent No. 851537, the foot arch support is inserted into the connection portion of the shoe sole, so that the user corrects the arch of the foot when walking to induce the development of the correct foot, and the rolling motion of the foot is naturally maintained. In order to prevent the deformation of the foot and the disease by distributing the load due to the weight, in the sole of the shoe consisting of the first half, the second half and the connecting portion connecting the first half and the second half, the foot portion is inserted into the foot support, the foot arch support Discloses a shoe sole inserted to be positioned from the inner end to the center of the connection. However, since the height of the foot arch support is determined, there is a problem that it is difficult to fit all the foot arches of different sizes.

In order to solve this problem, Korean Patent No. 912910 includes: a functional shoe having a foot arch support fixed to an accommodation groove formed in an outsole, the foot arch support being a base unit fixed to the accommodation groove; A slider screwed to the base unit and lifted by rotation; And a head coupled to the top of the slider and protruding into the shoe.

According to this patent, there is an effect that it is possible to provide a foot support of an appropriate height irrespective of the size of the foot of the wearer, but since the foot support is fixed, the load is concentrated on the foot support when walking, causing pain in the sole of the foot. There is this.

In addition, even if the foot arch support is applied, the weight is concentrated on the foot arch support, the effect of substantially dispersing the weight is insignificant.

Accordingly, it is an object of the present invention to provide a functional insole capable of uniformly dispersing weight over the sole of the foot.

Another object of the present invention is to provide a functional insole with improved breathability.

Another object of the present invention is to provide a functional insole that can minimize the noise of contact between the shoe and the ground.

The object is, in the insole that is fitted inside the shoe, hinged to the bottom of the inside of the shoe at a predetermined position in the longitudinal direction, extending from the calcaneus of the foot inserted into the shoe to the metatarsal and phalangeal boundary to the foot Achieved by a resiliently supported functional insole.

Preferably, the hinge engaging position may be a position corresponding to the bottom of the cubic bone.

In addition, the object is made of a single body, the body extends from the calcaneus of the foot to the metatarsal and phalangeal boundary to elastically support the foot, the body is arcuate in a predetermined position in the longitudinal direction of the body Is achieved by a functional insole that is bent into and hinged to the bottom of the shoe interior.

In addition, the above object, in the insole that is fitted inside the shoe, the sole support member for supporting the sole of the foot, and the heel support member for supporting the heel of the foot is combined, and from the calcaneus of the foot to the metatarsal border Extending to support the foot elastically, at the engagement position any one of the sole support member and the heel support member is achieved by a functional insole that is bent in an arc shape and hinged to the bottom of the shoe.

In addition, the above object, in the insole that fits inside the shoe, consists of a single body, the body extends from the calcaneus of the foot to the metatarsal and phalangeal boundary to elastically support the foot, in the longitudinal direction of the body An arc-shaped hinge member is coupled to the lower portion of the body at a predetermined position, and the hinge member is achieved by a functional insole hinged to the bottom of the shoe.

According to this structure, the weight can be uniformly distributed over the sole of the foot.

In addition, the air flow is smoothed by the hinge action, thereby improving air permeability.

In addition, by sufficiently absorbing the external impact can minimize the noise of contact between the shoe and the ground.

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

1 is a perspective view showing a functional insole according to an embodiment of the present invention, Figure 2 shows a state in which the functional insole according to the present invention is applied to a shoe worn on the foot.

As shown, the functional insole 10 consists of a single body 11 and consists of a sole support 12 supporting the sole, a hinge 13 and a heel support 14 supporting the heel.

Preferably, the body 11 may be injection molded from a metal or plastic material, but is not limited thereto.

In addition, preferably, the heel support portion 14 has a thickness of 1 to 1.5 mm and the sole support portion 12 has a thickness of 0.5 to 1 mm when the steel sheet is applied. Can be supported. The thickness of the body 11 may be appropriately selected according to the weight of the user, and importantly, the body 11 should be able to elastically support the weight sufficiently while being properly curved.

Preferably, the sole support 12 may be provided with a vent slot 15 or a vent ball for venting, and the heel support 14 may be provided with a recess 16 for accommodating the pointed calcanus 101 of the heel. You can make your heel rest comfortably.

In addition, the rear edge of the heel support 14 is preferably raised slightly to support the heel as if it is wrapped.

The hinge portion 13 formed at a predetermined position in the longitudinal direction of the body 11 may be configured by bending the body 11 itself in an arc or U-shape, and unlike this embodiment, a separate hinge member may be formed in the body 11. Can be attached to the lower surface of the The hinge part 13 is hinged to the bottom of the shoe to allow the body 11 to perform a hinge movement with respect to the hinge part 13, and at the same time, the sole support part 12 and the heel support part 14 are hinge parts. The body 11 is made elastic such as a leaf spring by being lifted from the bottom of the shoe inside by (13).

The position at which the hinge portion 13 is formed may be approximately a position corresponding to the lower portion of the cubic bone 102. Preferably, the toe node of the metatarsal 104 and the phalanx 105 at the heel calcanus 101 is 4 It may be a position divided by: 6.

The body 11 of the functional insole 10 of the present invention elastically supports the foot by extending from the calcaneus 101 of the foot inserted into the shoe to the boundary of the metatarsal 104 and the phalanx 105.

Referring to FIG. 2, an accommodating groove 31 is formed in an outsole or a midsole 30 of a shoe, and a hinge case 20 is fitted into and fixed to the accommodating groove 31, and an insole 10 is attached to the hinge case 20. The hinge portion 13 is fitted to the hinge movement is possible. In other words, the front sole support 12 and the rear heel support 14 are hinged like a seesaw about the hinge portion 13 fitted to the hinge case 20.

Preferably, the hinge case 20 may be manufactured by injection molding of a plastic material so that the hinge portion 13 of the insole 10 may smoothly operate the hinge, and should bear sufficient rigidity because it bears most of the weight. .

As shown in FIG. 2, the foot 100 moves from the calcaneus 101 constituting the heel to the cubic bone 102, the columnar bone 107, the tongue bone 103, the metatarsal bone 104, and the phalanges 105. It consists of various bones that follow. Reference numeral 108 denotes a tibia and 106 denotes a tibia.

In this structure, the weight pressure exerted along the tibia 108 is transmitted toward the toe along the vertebrae 101 of the heel, as well as the scapula 107, tongue tongue 103, and metatarsal 104. As a result, the weight pressure is concentrated on the heel of the calcaneus 101 and the toe node by the boundary of the metatarsal 104 and the phalanx 105, resulting in fatigue of the foot arch 110 of the sole.

In order to solve this problem, conventionally, the foot arch support 110 is applied to the foot arch arch 110 of the sole. When the height of the foot arch support is increased, the weight pressure is concentrated on the foot arch arch 110, and the height of the foot arch support becomes low. No effect is obtained. In addition, even if the height is properly adjusted, while walking, the impact from the floor is transmitted to the foot arch arch 110 through the foot arch support to feel the pain.

However, according to the functional insole of the present invention, the weight pressure is configured to extend from the calcaneus 101 of the foot to which the weight pressure is transmitted to the boundary of the metatarsal 104 and the phalanx 105, thereby causing the calculus 105 at the calcaneus 101. It is possible to obtain the effect of continuously and uniformly dispersing up to. In addition, since the sole and the heel are elastically supported by the leaf spring effect by the sole support 12 and the heel support 14, the shock can be sufficiently absorbed from the outside of the shoe.

Herein, the elastic support means that the sole support part 12 and the heel support part 14 have a leaf spring tension in a vertical direction with respect to the hinge part 13 while being spaced apart from the inner bottom of the shoe. Means to support the heel.

On the other hand, as described above, in the three-step walking method of walking from the heel to the sole, the big toe root portion in order to walk forward, first press the ground with the heel to press the heel support 14 Since the sole support 12 is lifted up by the hinge action of the hinge part 13, the sole support part 12 is elastically supported in close contact with the sole of the up state. Then, when the sole touches the ground for the next step and the heel is lifted and the toe node is pressurized, the heel support 14 is lifted up by the hinge action of the hinge 13 in the same principle as above. Closely and elastically support effectively. By repeating this process, the walking is performed, so that the pressure applied to the foot arch arch 110 can be uniformly dispersed as a whole.

In addition, when the foot arch support is conventionally applied, the space inside the shoe is narrowed by the foot arch support, so that it is difficult to put or remove the foot in the shoe, but in the case of the present invention, the foot is in the state in which the insole is inserted into the shoe by the hinge action. It is easy to put in and take out. That is, when the foot is put into the shoe, the sole support 12 is pressed by the sole that is inserted first, so that sufficient space is provided in the front, so that the foot can be easily fitted.

Moreover, the air circulation inside the shoe is smoothed by such a hinge action, and in particular, as the air circulates through the ventilation slots 15 as shown in FIG. 1, odors can be removed.

In addition, the effective noise distribution and the sufficient absorption of the external impact by the leaf spring tension can minimize the noise of contact between the shoes and the ground.

Figure 3 shows a functional insole according to another embodiment of the present invention.

According to this embodiment, the functional insole 30 is the sole support 32 and the heel support 34 is coupled by a rivet 35 or the like. Here, the hinge part 33 is integrally formed with the heel support part 34, but may be integrally formed with the sole support part 32. Welding may be used instead of the rivet 35.

Figure 4 shows a functional insole according to another embodiment of the present invention.

According to this embodiment, a separate hinge member 43 is coupled to the lower surface of the single body having the sole support 42 and the heel support 44 by a rivet 45 or the like. Welding may be used instead of the rivet 45.

On the other hand, although not shown, it may be composed of a cylindrical bracket attached to the lower surface of the body as a separate hinge member and a fixed shaft installed through the bearing inside the bracket. Both ends of the fixed shaft are fixed to both sidewalls of the hinge case, so that the bracket can be freely rotated by the bearing, so that the body to which the bracket is fixed is hinged.

In addition, in the above embodiment, the installation of the functional insole directly inside the shoe has been exemplified, but a soft cover may be laminated on the functional insole of the present invention. In other words, the functional insole of the present invention can not support the toe of the front of the phalanx because it is from the heel to the toe node of the metatarsal and phalangeal border, so that the soft cover of the size covering the entire inside of the shoe is used on the functional insole Can be.

As such, the invention is susceptible to various modifications and variations at the level of those skilled in the art. Therefore, the scope of the present invention should not be limited to the above embodiments but should be interpreted by the claims described below.
