RECTIFICATION APPARATUS FOR FEET EQUIPPED WITH SHOCK ABSORBING MEMBERS

Technical Field

[1] The present invention relates to a rectification apparatus for a feet, and more particularly to a rectification apparatus for feet, which includes a body having a hole formed for preventing contact of a bone in the heel of the feet and a hole formed for junction with shock absorbing members, and shock absorbing members made by ejaculation and jointed to the body, so as to absorb shocks whenever a user uses the rectification apparatus for feet and improving junction force between the shock absorbing members and the body. Background Art

[2] Generally, a feet rectification device is a device for rectifying an abnormal foot into a shape of a normal foot by using a specific configuration.

[3] Now, such a feet rectification device is described on the basis of a flat foot as an example.

[4] In a normal case, when a person stands upright, outer edges of the sole of the foot and a front side of the heel of the foot are just contacted with the ground, but an inner portion of the sole of the foot is separated from the ground in an oval shape. This oval- like inner portion is called 'Jangsim', and such a shape of the inner portion of the sole relieves shocks when a person walks, thereby protecting brain and blood vessels in the sole of the foot.

[5] An abnormal foot, called a flat foot, has no oval shape, so the entire sole is contacted with the ground. In this case, all shocks are transferred to a person, so the person feels fatigue easily.

[6] In order to rectify such a flat foot, an arch-shaped rectification device is conventionally used to form such an oval shape on the sole of the foot.

[7] Hereinafter, the conventional arch-shaped rectification device is described with reference to Fig. 1.

[8] A conventional rectification device 10 has an arch portion 11 formed convex upward on one side toward the inner portion of the sole, and a seating portion 12 formed concave downward on the opposite side so that the heel of a foot of a user is seated thereon.

[9] By using such configuration, if the user wears the rectification device 10, an oval shape is formed on the sole by means of the arch portion 11, and the user may wear the rectification device stably by means of the seating portion 12.

[10] However, the conventional rectification device is made of rigid material in order to prevent deterioration of durability or deformation of its shape. Such rigid material is however collided with the heel of the foot on which weight of the user is concentrated, so shocks are transferred to the user as they are, thereby deteriorating health and functionality of the foot.

[11] In addition, an inner portion of the sole of the foot is contacted with the arch portion

11, so a sharp shape at the end of the arch portion 11 may cause pains or wounds on the sole of the user. Disclosure of Invention Technical Problem

[12] The present invention is designed in consideration of the above problems of the prior art, and therefore an object of the invention is to provide a rectification apparatus of feet, which has shock absorbing members installed thereto to absorbing shocks, has a hole formed at a position contacted with a bone in the heel of a foot so as to prevent the bone of the heel of the foot from directly contacting with the rectification apparatus and thus prevent shocks from being transferred to a user, and having a curved portion formed at an end of an arch portion so as to prevent the sole of a foot from being damaged and also improve functionality of the rectification apparatus. Technical Solution

[13] This object may be accomplish using configuration that shock absorbing members are installed to a body acting as a rectification apparatus, and a hole is formed at a position contacted with a bone of the heel of a foot so that the bone of the heel is not contacted with the body.

[14] At this time, a curved portion is preferably formed at an end of the arch portion.

Best Mode for Carrying Out the Invention

[28] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[29] As shown in Fig. 2, a rectification apparatus 100 of the present invention includes a body 110 for rectifying feet of a user, and shock absorbing members made by ejaculation and jointed to the body 110. The shock absorbing members 120 are jointed to the body 110 to surround the body 110 (see Fig. 3).

[30] To describe the body 110 with reference to Fig. 4, a portion of the body 110 that is surrounded by the shock absorbing members 120 has a shock absorbing hole 112. The shock absorbing hole 112 is designed so that the heel of a foot of the user is not contacted with the body 110. By means of the shock absorbing hole 112, a bone of the heel of the user is contacted with the shock absorbing members 120, so shocks are not transferred to the user who wears the rectification apparatus (see Figs. 5 and 7).

[31] In addition, the shock absorbing members 120 are preferably made of material that is capable of preventing slippery. Such material may give convenience to the user when the user uses the rectification apparatus 100 of the present invention as an insole since the foot is not slip thereon.

[32] Meanwhile, an arch surface 111 for rectifying the sole of the user is formed in a portion of the body 110 of the rectification apparatus 100 according to the present invention, which is not surrounded by the shock absorbing members 120, and a seating surface 114 is formed in a portion where the shock absorbing hole 112 is formed.

[33] The arch surface 111 is convex upward to form an oval shape on the sole of a flat foot. The arch surface 111 keeps pushing the sole of a flat foot to form an oval shape, resulting in rectifying the sole.

[34] In addition, the seating surface 114 is formed in a portion of the body 110, which is

contacted with heel of a foot.

[35] The seating surface 114 is concave downward so that a rear side of the heel of the user is caught by the seating surface 114. By means of such configuration, the user may use the rectification apparatus 100 of the present invention in a more stable way.

[36] Around the shock absorbing hole 112, junction holes 113 are formed at regular intervals. The junction holes 113 have a smaller diameter than the shock absorbing hole 112, and improves jointing ability between the shock absorbing members 120 and the body 110, as described below with reference to Fig. 5.

[37] As mentioned above, the junction holes 113 are arranged around the shock absorbing hole 112 at regular intervals. At this time, the shock absorbing members 120 are jointed to the body 110 by means of ejaculation as mentioned above. When using the ejaculation as mentioned above, the shock absorbing members 120 are connected up and down by means of the junction holes 113.

[38] The shock absorbing members 120 interconnected through the junction holes 113 improve junction ability with the body 110. That is to say, since the junction holes 113 are arranged around the shock absorbing hole 112 and fix the shock absorbing members 120 not to be deviated from the body 110, the performance of the rectification apparatus is not deteriorated even the rectification apparatus is used for a long time.

[39] Meanwhile, an inner portion of the sole of a foot is contacted with the arch portion

111 to rectify a flat foot. At this time, if an end of the arch portion 111 is sharp, the sole of the foot of a user may be harmed. Thus, in the present invention, a curved portion 11 Ia is formed on the arch portion 111 so that the sole of a foot is not harmed though the sole is contacted with the arch portion 111 (see Fig. 6).

[40] As described above, the present invention absorbs shocks by installing the shock absorbing members 120 to the body 110 for rectifying feet, and the shock absorbing members 120 are jointed to the body 110 by means of ejaculation as mentioned above.

[41] Hereinafter, another embodiment of jointing the shock absorbing members 120 is described.

[42] Fist, a hot melting material may be used as the shock absorbing members 120 for jointing as described below (see Fig. 7).

[43] The hot melting material is defined as a material that is adhered by heating and melting solid polymer. In the present invention, such a hot melting material is jointed to the body 110 and then used as the shock absorbing members 120.

[44] In addition, as mentioned above, the hot melting material has an adhesive ability, so it may be used to joint the aforementioned shock absorbing members 120 to the body 110. That is to say, a hot melting material 120-1 is adhered to the body 110, and then the shock absorbing members 120 are jointed on the hot melting material 120-1 (see

Fig. 8).

[45] Meanwhile, it is also possible to coat an adhesive 120-2 on the body 110 and then joints the shock absorbing members 120 thereto. That is to say, after the adhesive 120-2 is sufficiently coated on the body 110, the shock absorbing members 120 are inserted so that they are jointed with the body 110 (see Fig. 9).

[46] Heretofore, a method for jointing the shock absorbing members 120 by means of different materials is described. Now, a method for jointing the shock absorbing members 120 themselves is described.

[47] Referring to Fig. 10, the shock absorbing members 120 includes an upper shock absorbing member 121 and a lower shock absorbing member 122. The upper shock absorbing member 121 is positioned on an upper portion of the body 110, and it has protrusions 121a on its lower portion, which are formed in correspondence with the junction holes 113. The protrusions 121a pass through the junction holes 113 and are then contacted with the lower shock absorbing member 122, and then they are jointed thereto by hot melting.

[48] At this time, it is also preferred that insert holes 122a are formed on the lower shock absorbing member 122 so that the protrusions 121a are inserted therein (see Fig. 11).

[49] That is to say, though the protrusions 121a are formed at the same positions on the upper shock absorbing member 120, the insert holes 122a are also formed in the lower shock absorbing member 122 so that the protrusions 121a are inserted therein. By using this configuration, if the protrusions 121a are inserted into the lower shock absorbing member 122 and then adhered thereto by means of hot melting, stronger adhesive force is obtained rather than the aforementioned adhering method.

[50] Meanwhile, a shape of the shock absorbing hole 112 is not limited to a circular shape. That is to say, the shock absorbing hole 112 may have a rectangular shape (see Fig. 12) or a star shape (see Fig. 13).

[51] As described above, the present invention is configured so that the shock absorbing hole 112 is formed at a position contacted with the bone in the heel of a foot, thereby preventing shock from being transferred to the user and improving adhesive force between the body 110 and the shock absorbing members 120. Now, it is described how to use the present invention with reference to Fig. 14.

[52] In this example, the feet rectification apparatus 100 of the present invention is used as an insole of a shoe. As shown in Fig. 7, in the case that the feet rectification apparatus 100 is put in a shoe and then a user wears the shoe, the bone of the heel of the user is contacted with a portion occupied by the shock absorbing hole 112 as mentioned above. By using this configuration, the bone in the heel of the user is not contacted with the body 110 but is contacted with the shock absorbing member 120 so that shocks are not transferred to the user.

[53] In addition, since the shock absorbing members 120 are interconnected through the body 110 through the junction holes 113, the shock absorbing members 120 are more stably adhered to the body 110.

[54] Moreover, by means of the arch surface 111 having the curved portion 11 Ia as mentioned above, the rectification apparatus of the present invention forms a normal oval shape on the sole of the user to rectify the sole, and the seating surface 114 allows the heel of the user to be stably positioned. Thus, the user may use the rectification apparatus 100 of the present invention in a more convenient way. Industrial Applicability

[55] As described above, the rectification apparatus of the present invention is configured so that the shock absorbing members 120 are mounted to the body 110 for rectifying the foot in order to absorb shocks, the shock absorbing hole is formed at a portion contacted with the bone in the heel of a user, and the shock absorbing members 120 are interconnected through the body 110 by means of the junction holes 113. Thus, the rectification apparatus prevents shocks from being transferred to the user and improves adhesive ability between the shock absorbing members 120 and the body 110. Therefore, the user may use the rectification apparatus 100 of the present invention in a more stable way without shocks, so the present invention improves functionality of the rectification apparatus and improves health of the foot of the user.

[56] In addition, since the curved portion 11 Ia is formed on the arch surface 111, the present invention prevents the sole from being damaged. Moreover, by means of the slippery-preventing function of the shock absorbing members 120, a user may use the rectification apparatus in a more stable way without slippery in case that the rectification apparatus is used as an insole of a shoe.
