Description

  The present invention relates to a detachable wedge heel applied to high heel shoes, and more particularly to a detachable wedge heel that can be detachably coupled to a high heel shoe having a thin and high heel.

  There are a variety of shoes that are thin and have high heels. In recent years, the height of the heel of shoes has become higher, while the width of the heel has become narrower. Such a thin and high heel or shoe including such a heel has been referred to as a “pin heel”, “kill heel” or “Stiletto heel”. Shoes that are thin and have high heels throughout this specification are defined as “high heel shoes”.

  High heel shoes not only have a small surface area on the heel that contacts the ground, but also keep a person's heel away from the ground. Therefore, the concentrated load from the ground is transmitted to the wearer's foot through the thin heel. For this reason, the wearer feels great inconvenience and fatigue. However, many women love high-heeled shoes with a sense of inconvenience and fatigue. Many working women wear high heels as they are outdoors, but tend to switch to sneakers and relatively easy shoes prepared in the room, especially in the workplace.

  On the other hand, there are wedge heel shoes including a wedge heel as a heel instead of a thin heel such as a pin heel, a kill heel and a stiletto heel. Such a wedge heel shoe can be easily worn by the wearer despite having a high heel because the surface area of the heel contacting the ground is large. However, despite the advantages of such wedge heel shoes, the popularity of high heel shoes including heels such as kill heels is still high.

  In the past, attempts and research have been made to change the structure and form of the heel in order to make it easier for the wearer to wear high-heeled shoes. However, such attempts and research require changes in the design of the high heel shoes themselves and are uneconomical, making it difficult to meet consumer needs.

  One problem to be solved by the present invention is a removable wedge heel that can be easily attached to a high heel shoe and used as a wedge heel shoe without structural changes or deformation of the high heel shoe. Is to provide.

  Another problem to be solved by the present invention is to provide a method for customizing a detachable wedge heel that processes and customizes a wedge heel that can be harmoniously coupled to a specific high heel shoe.

  The present invention provides a removable wedge heel for high heel shoes. The high heel shoes are formed with an upper inclined surface corresponding to an inclined sole of the high heel shoes, a bottom surface that intersects the upper inclined surface and contacts the ground, and an upper portion of the upper inclined surface toward the bottom surface. And a heel insertion hole inserted in close contact with the heel of the high heel shoe.

  In consideration of the case where the heel is inserted into the heel insertion hole but does not adhere, in this case, the wedge heel and the high heel shoe cannot be coupled without structurally changing or deforming the high heel shoe. Even if an additional fixing means is introduced between the high heel shoes and the wedge heel, it is essential that the heel insertion hole and the heel are fixed by inserting the heel of the high heel into the heel insertion hole of the wedge heel. It is.

  According to one embodiment, the removable wedge heel is made of a viscoelastic material at least around the heel insertion hole.

  According to an embodiment, the removable wedge heel may further include a pair of fixing clips provided on both side surfaces of the lower portion of the upper inclined surface and in contact with both side surfaces near the sole of the high heel shoe.

  According to one embodiment, the pair of securing clips is made of a transparent material.

  According to an exemplary embodiment, the removable wedge heel may further include a non-slip portion formed on the upper inclined surface.

  According to another aspect of the present invention, there is provided a method for customizing a detachable wedge heel that recognizes the shape of a high heel shoe and processes the semi-finished product according to the recognized shape of the high heel shoe to produce a detachable wedge heel. . At this time, the removable wedge heel includes a heel insertion hole that is inserted in close contact with the heel of the high heel shoe.

  According to one embodiment, the semi-finished product is pre-formed with the heel insertion hole or a corresponding basic insertion hole, and the semi-finished product is surface-treated to correspond to the inclined sole of the high heel shoe. An upper inclined surface is formed.

  According to one embodiment, the surface processing is performed using a laser.

  According to the present invention, it is possible to transform a high-heeled shoe into a comfortable wedge-heeled shoe by combining the removable heel with a high-heeled shoe that feels tired and inconvenient due to a high and thin heel in a simple manner. . The removable wedge heel according to the present invention has the advantage that it will not cause any damage or change to the high heel shoe itself. The wearer can conveniently select and use high heel shoes and wedge heel shoes by attaching or separating the wedge heel. The present invention provides the advantage that the wedge heel can be easily customized according to the shape of the high heel shoe.

  Referring to FIG. 1, a high heel shoe 10 includes high and thin heels 12 referred to as “pin heel”, “kill heel” or “Stiletto heel”. Further, the high heel shoe 10 includes an inclined shoe sole 14 that is inclined downward from the vicinity of the upper end of the heel 12 to the vicinity of the toe. When a person wears the high heel shoes 10, the inclined sole 14 forms a substantially triangular space between the ground and the ground without substantially contacting the ground. As described above, the thin and high heel 12 of the high heel shoe 10 applies a concentrated load to the sole due to a small contact area with the ground, which makes the wearer feel great inconvenience and fatigue.

  Referring to FIG. 2, a removable wedge heel 20 according to one embodiment of the present invention is coupled to a high heel shoe 10. The heel 12 of the high heel shoe 10 is concealed in the wedge heel 20 by the coupling of the detachable wedge heel 20, and the detachable wedge heel 20 functions as a heel, and the high heel shoe 10 is a wedge heel shoe. It is transformed into the form. At this time, the upper inclined surface of the detachable wedge heel 20 is in contact with the inclined sole 14 (see FIG. 1) of the high heel shoe 10, and the wide bottom surface of the detachable wedge heel 20 is in contact with the ground with a large surface area. The detachable wedge heel 20 fills the entire space between the heel 12 and the toe of the high heel shoe 10. Thereby, the said detachable wedge heel 20 can give the wearer good comfort.

  Further, the removable wedge heel 20 is made of a viscoelastic material having excellent buffering properties such as latex, gel, cork, and / or polyurethane, so that the wearer can be given further comfort.

  Referring to FIGS. 3 and 4, a removable wedge heel 20 according to an embodiment of the present invention includes an upper inclined surface 20a that is inclined downward from the rear side toward the front side, and a lower portion of the upper inclined surface 20a. And a bottom surface 20b provided so as to intersect with the ground.

  Further, the detachable wedge heel 20 is provided on the heel insertion hole 22 formed deeply in a substantially vertical direction from the upper portion of the upper inclined surface 20a toward the bottom surface 20b, and on both side surfaces of the lower portion of the upper inclined surface 20a. And a plurality of anti-slip portions 26 provided on the upper inclined surface 20a. The removable wedge heel 20 is generally made of a viscoelastic material, and a rigid cover 27 can be attached to the side surface to produce a beautiful design or color.

  The material of the rigid cover 27 is preferably a plastic material, but other materials such as metal may be used. Even when the rigid cover 27 is used, it is preferable that a part of the height region 28 adjacent to the bottom surface of the removable wedge heel 20 exposes a viscoelastic or compressible material.

  The heel 12 (see FIGS. 1 and 2) of the high heel shoe 10 is fitted into the heel insertion hole 22 exactly. This is not limited to the fact that the heel 12 is fitted to the heel insertion hole 22 over the entire depth of the heel insertion hole 22, but only in a part of the depth of the heel insertion hole 22. It also means that the heel 12 fits snugly into the heel insertion hole 22.

  For this reason, it is preferable that the size of the heel insertion hole 22 is slightly smaller than the size of the heel 12 in at least a part of the depth of the heel insertion hole 22. In this case, when the heel 12 of the high heel is inserted into the heel insertion hole 22, the periphery of the heel insertion hole 22 is elastically compressed, and the inner surface of the heel insertion hole 22 strongly adheres to the surface of the heel 12. . If at least the periphery of the heel insertion hole 22 is made of a viscoelastic material, the periphery of the heel insertion hole 22 can be elastically deformed when the heel 12 is inserted.

  The depth of the heel insertion hole 22 is formed to be greater than the height of the heel 12 of the high heel shoe 10. Further, the heel insertion hole 22 may have a structure in which the lower part is closed, or alternatively, a penetration structure in which the lower part is opened.

  The pair of fixing clips 24 are provided on both side surfaces of the lower portion of the inclined surface 20a and are in contact with and meshing with both side surfaces of the high heel shoe 10 (see FIGS. 1 and 2). The pair of fixing clips 24 are provided to prevent the removable wedge heel 20 from being twisted in the rotational direction with respect to the high heel shoe 10. When the twist of the wedge heel 20 is suppressed only by the close insertion of the heel 12 with respect to the insertion hole 22, the fixing clip 24 may be omitted. The securing clip 24 is preferably made of a transparent material in order to minimize the influence on the design of the high heel shoe 10.

  The anti-slip portion 26 is made in a plate shape and is affixed on the upper inclined surface 20a.

It can be attached to the surface 20a for a long time.

  The wedge heel 20 described above can be processed and sold at a store specializing in it. At this time, a method for customizing a wedge heel for processing a wedge heel according to a high heel shoe worn by a consumer can be provided as in the following embodiment.

  As shown in FIG. 5, a method for customizing a detachable wedge heel according to an embodiment of the present invention includes a wedge heel semi-finished product preparation step (P1), a high heel shoe shape recognition step (P2), and a semi-finished product. Process step (P3). The semi-finished product processing step (P3) may include a surface processing step (P31) and an insertion hole processing step (P32). The method for customizing the detachable wedge heel may be performed by an automated device, or may be performed by an operator or an expert.

  In the present embodiment, the method for customizing the wedge heel by the automated device is mainly described. However, it should be noted that this does not exclude the manual customization method by the operator.

  In the wedge heel semi-finished product preparation step (P1), a wedge heel semi-finished product is prepared in advance. At this time, as shown in FIG. 6A, the semi-finished product may not include the basic shape of the wedge heel and the basic insertion hole, and is shown in FIG. 6B. As shown in FIG. 6C, the wedge heel has the basic shape of the wedge heel and does not need to include the basic insertion hole. And may include a basic insertion hole, and may include both a basic shape of the wedge heel and a basic insertion hole as shown in FIG. 6 (d). .

  In the shape recognition step (P2) of the high heel shoes, the shape and size of the inclined sole of the high heel shoes and / or the shape and size of the heel are recognized. In the case of manual work, the shape is recognized with the naked eye by an operator or an expert, but when using an automated device, the shape of the high heel shoes must be recognized using a known three-dimensional shape recognition program. Can do. The recognized shape information, that is, the shape and size of the slanted sole of the high heel shoe and the shape and size of the heel are stored as three-dimensional coordinate information in a memory of a computer or an automated device.

  As described above, the semi-finished product processing step (P3) may include a wedge heel surface processing step (P31) and an insertion hole processing step (P32), and the surface processing step (P31) For example, the surface of the semi-finished product is processed by means such as a laser. At this time, as described above, surface processing can be automatically performed based on the recognized and stored three-dimensional coordinate information. Depending on the semi-finished product, the degree of surface processing may be different, and when using the semi-finished product shown in FIG. 6 (a), the processing for producing the basic shape of the wedge heel must be performed first. First, when using the semi-finished products shown in FIGS. 6 (b) and 6 (d), the wedge heel has a basic shape, so it corresponds to the shape of the inclined sole of the high heel shoe. Even surface processing that finely adjusts the upper inclined surface of the wedge heel is sufficient.

  The insertion hole processing step (P32) may be performed by adjusting the size and shape of a basic insertion hole formed in advance in a semi-finished product to match the heel of the high heel shoe. Since the heel insertion hole is elastically deformed and inserted in close contact with the heel of the high heel shoe, a basic shape prepared in advance may be used as it is. Only when necessary, the heel insertion hole is processed by expanding the insertion hole. Even if the surface processing step (P31) is performed by an automated device, the insertion hole processing step (P32) is not necessarily performed by the automated device.

  When using a semi-finished product as shown in FIGS. 6A and 6B in which a basic insertion hole is not formed, forming the heel insertion hole is also the insertion hole processing step (P32). include.
