Definitions

  • the present disclosure relates to a heel-reinforced shoe in which a mounting structure of a detachable member replaceably mounted on the heel body is reinforced so as to improve the abrasion and damage resistance not only of the detachable member, which is replaceable, but also of the heel body, which is integrated with the shoe and thus is non-replaceable.
  • shoes each having a heel protruding downward, are variously classified into leather shoes, formal shoes, high-heeled shoes, loafers, and boots.
  • Such shoes may be manufactured in such a manner that the lower end of each heel, which comes into contact with the ground and is thus easily worn out, includes a detachable heel member, whereby the shoes can be used merely by replacing the heel member.
  • a groove is formed in a bottom surface of the heel and a fixing pin is provided on the top surface of the heel member, so that the fixing pin is inserted into the groove, thereby fixing the heel member to the heel.
  • the heel member may be removed by pulling the fixing pin out of the groove, and a new heel member may be installed. Accordingly, it is possible to use the shoes for a long period merely by replacing the easily worn-out heel member.
  • the heel is formed of a rigid synthetic resin material, a surface of the heel, which is in contact with the heel member, i.e. the bottom surface of the heel may be worn out. Even though the heel member is fixed to the heel through fitting-fixing between the groove and the fixing pin, the top surface of the heel member and the bottom surface of the heel are in plane contact with each other. Thus, a strong impact is applied to the heel members when a user walks with the shoes, a contact surface therebetween may be worn out and, in particular, a corner of the contact surface may be damaged due to slight shaking.
  • the heel member since the heel member is manufactured to be smaller and thinner than the heel in order to emphasize the beauty of the curve of the heel member, the heel member may be easily damaged, rather than worn out from the bottom surface thereof, which comes into contact with the ground, when a strong impact is applied thereto. Thus, the heel member needs to be frequently replaced.
  • heels which are sensitive to fashions, like dresses, and thus when the heels, which are hardly replaced, become scratched, the user may have desire to replace his/her shoes and may thus buy new shoes.
  • the shoes may not be used for a long time.
  • Korean Patent No. 10-1201844 filed and registered in the name of the applicant of the present disclosure, discloses a detachable heel member, in which, in configuring the detachable heel member on a heel, a heelpiece, which comes into contact with the ground, is made to be movable up and down and a shock-absorbing member is incorporated therein, so that an impact applied to the heel is buffered by the shock-absorbing member.
  • a groove is formed in the heel and an insertion portion (a constituent element corresponding to the fixing pin of Korean Patent No. 10-1017789 ) to be inserted into and fixed to the groove in the heel is formed in the top surface of the heel member.
  • the heelpiece which may be easily worn out or damaged, may be easily removed from the heel member such that the shock-absorbing member, the shock buffering function of which deteriorates upon long-term use, may also be easily removed from the heel member so as to be replaced and the entire heel member may also be easily replaced.
  • shock-absorbing shoes which can be used for a long period at a low cost by replacing only some of the constituent elements of the easily detachable heel member of the heel.
  • Korean Patent No. 10-1201844 filed in the name of the applicant of the present disclosure, a structure, in which a projection of a heel member is inserted into and fixed to the groove of the heel is provided, as in Korean Patent No. 10-1017789 .
  • the bottom surfaces and corners of the heels may be easily worn out or damaged, and the replaceable heel members may also be easily damaged.
  • the present disclosure was made in order to solve the problems described above, and an object of the present disclosure is to provide a heel-reinforced shoe, which can be manufactured in such a manner that the endurance of a heel is improved by detachably installing a heel member to the heel, and the heel member, which is replaced and used, is protected so that the usable lifetime of the heel member can be significantly increased, and the overall appearance of the heel can be made to be beautiful even though the heel member is detachably installed.
  • another object of the present disclosure is to provide a shoe which is provided with a heel, which is easily detachable and mountable and is improved in elasticity, and in which a heelpiece shock-absorbing member is made to absorb a load while sliding up and down within a heelpiece body when the load if the weight of a user is applied thereto, and if necessary, the heelpiece shock-absorbing member as well as the heelpiece body can be easily removed to thus be repaired or to be replaceably used, whereby the endurance of the shoe can be improved and economic efficiency and convenience can be remarkably improved.
  • the present disclosure provides a heel-reinforced shoe provided with a heel including: a heel body fixed to a rear portion of the bottom surface of the shoe, and having a groove formed in the bottom surface thereof; and a detachable member including an insertion portion inserted into and fixed into the groove in the heel body, and an upper contact surface formed around the insertion portion to be in close contact with the bottom surface of the heel body, so that the detachable member is made to be replaceable.
  • the shoe further includes a reinforcing frame made of a metal material and interposed between the upper contact surface of the detachable member and the bottom surface of the heel body, the reinforcing frame includes a side cover portion bent to extend downwards from the peripheral edge of the upper contact surface so as to cover the side surface of the detachable member, and the side cover portion is formed to protrude outwards from the side surface of the lower portion of the heel body.
  • a heelpiece is mounted on the bottom portion so as to be in contact with the ground such that the heelpiece is introduced into the detachable member in a piston-like manner so as to move up and down, and an elastic member is incorporated in the detachable member so as to buffer an impact applied to the heelpiece.
  • the elastic member includes one or multiple compression springs.
  • a long bolt is provided so as to be slidable up and down, and when multiple compression springs are provided, a long bolt is provided to be slidable up and down between the compression springs.
  • a guide protection tube is further provided and the long bolt is installed by being inserted into the guide protection tube.
  • a notch is formed in the lower end of the heel body such that the detachable member is separated from the heel body by inserting a ring into the notch and pulling the detachable member downward.
  • the side cover portion of the reinforcing frame protrudes outwards from the side surface of the heel body.
  • the reinforcing frame is interposed between the heel body and the detachable member, it is possible to prevent the abrasion of the heel body even if the detachable member is shaken with respect to the heel body.

  • the detachable member which includes the elastic member therein, is prevented from being damaged by the reinforcing frame, so that the detachable member can be used for a long period merely by replacing the heelpiece.
  • the notch is formed in order to enable the mounted detachable member to be easily separated, and it is possible to prevent the detachable member from being damaged when separating the detachable member using the notch.
  • the lower end of the heel body which may be damaged by being placed close to the ground, can be protected by the reinforcing frame, which protrudes outwards from the side face of the lower end of the heel body.
  • heel bodies and detachable members which constitute heels in different embodiments, are differently configured depending on embodiments, and constituent elements, in which upper contact surfaces are formed in the detachable member, are different from each other depending on the embodiments, the heel bodies, the detachable members, and the upper contact surfaces will be denoted by the same reference numerals, respectively.
  • a heel-reinforced shoe includes an upper configured to receive a human foot, an insole provided on a bottom surface inside the upper so that the sole of a foot is in contact with the insole, an outsole provided on the bottom side of the insole to come into contact with the ground, and a heel 100 or 200 installed to the rear portion of the outsole to protrude downwards so as to lift a foot heel.
  • the heel 100 or 200 includes: a heel body fixed to the rear portion of the bottom surface of the outsole; a detachable member detachably mounted on the lower portion of the heel body so as to come into contact with the ground and support the heel body, and including a heelpiece, which is mounted on a bottom portion of the heel body to come into contact with the ground, the heelpiece being mounted to be introduced into the detachable member like a piston so as to move up and down, and an elastic member incorporated in the detachable member such that an impact applied to the heelpiece is absorbed by the elastic member, which is compressed when the heelpiece is introduced into the detachable member; and a reinforcing frame, which wraps a portion, which is in contact with the heel body, on the surface of the detachable member so as to prevent the detachable member and the heel body from being worn out or damaged, whereby the heel has a structure that improves endurance while relieving an impact applied through the heel 100 or 200 while a user walks in the state of wearing the shoe.
  • the upper, the insole, and the outsole are not limited to the shapes illustrated in the accompanying drawings of the present application, and may be modified in various forms depending on types of shoes. Since the shapes, structures, materials, and the like thereof are known in the related art, detailed descriptions thereof will be omitted.
  • the detachable member can be mounted by inserting the insertion portion, which protrudes upward from the detachable member to be described later, into the groove. After being mounted, the detachable member can be separated as necessary.
  • the groove includes a lower space portion formed in a lower side, a bottle-neck space portion formed in a middle portion to be narrower than the lower space portion such that a lower end step is formed at the boundary between the bottle-neck space portion and the lower space portion, and an upper space portion formed in an upper side to be wider than the bottle-neck space portion such that an upper end step is formed at the boundary between the bottle-neck space portion and the upper space portion.
  • the upper space portion is formed to penetrate the upper surface of the heel body, and the groove is formed vertically through the heel body. Accordingly, when the outsole is penetrated at the position of the upper space portion and the rear portion of the insole is configured to be removed, a long bolt can be inserted through the upper space portion even in the state in which the heel body is fixed to the bottom of the rear portion of the outsole.
  • the detachable member includes: an insertion portion, which is detachably inserted into and fixed to the groove in the heel body so as to make the detachable member detachable from the heel body; an upper contact surface formed around the insertion portion to be in close contact with the bottom surface of the heel body; and the heelpiece, which comes into direct contact with the ground.
  • the detachable member is provided with an inner space, the lower portion of which is opened, and the elastic member is inserted into the inner space.

  • the elastic member includes a first shock-absorbing material mounted to directly abut on the inner end step, a compression spring vertically erected such that the upper end thereof abuts on the first shock-absorbing material, and a second shock-absorbing material that wraps the compression spring along the outer periphery thereof. Accordingly, when compressed by the heelpiece, the compression spring and the second shock-absorbing material are simultaneously contracted, so that elastic restoring force generated by each of the compression spring and the second shock-absorbing material is exhibited, and the first shock-absorbing material is also contracted by the contraction of the compression spring and the second shock-absorbing material, so that elastic restoring force is exhibited.
  • the elastic member is configured to execute a dual shock-absorbing action by the compression spring and the second shock-absorbing material and a multi-stage shock-absorbing action by the addition of the first shock-absorbing material, so that compared to the case in which only the compression spring is installed, an impact may be received in a more distributed manner and the life span of the compression spring may also be extended.
  • the diameter of the inner cross section of the compression spring is set to be larger than the outer diameter of the long bolt.
  • the second shock-absorbing material wraps the compression spring, which causes the compression spring to be stably maintained in an erected state and also prevents the compression spring and the long bolt from coming into contact with each other.
