Description

  The present invention relates to a shoe having a sole that can be sized according to the sole of the user and a method for adjusting the size of the sole of the shoe according to the sole of the user. According to the characterizing part of the claim.

  A shoe of the kind described above, i.e. a shoe having a sole that can be adapted to the unique size of the sole of the shoe user, faces the problems encountered and described in the previous literature. Long known as having.

  Patent Document 1 describes a shoe having a shoe sole including an insert formed of a deformable material capable of stretching the shoe sole, and a screw member for maintaining the shoe sole in a desired stretched state. Has been.

  Patent Document 2 has an insert and / or an opening that can deform the sole in different directions, and the deformation can be adapted to the specific size of the sole of the shoe user. In addition, the literature describes various means for maintaining the shoe sole in a preferable deformed state, that is, a member including a string, a rack-type member, and a member for clamping with a screw. Etc. are described.

  Similar techniques for solving the above problems are also described in Patent Documents 3 to 9.

  All these prior patents use mechanical means that complicate the manufacture and assembly of the shoe to keep the shoe sole in a favorable deformed state, so it is not easy to implement and is subject to wear. If it breaks, it is generally necessary to replace the entire shoe. Another means for the use of mechanical means to keep the shoe sole in a favorable deformed state is described in US Pat. This document uses a T-shaped rigid insert that is inserted into a suitably formed seat provided in the body of the shoe sole.

  This measure also has several drawbacks. The first disadvantage is that due to the presence of the insert of the protruding member snap-engaged in each hole provided in the sole of the shoe for fitting the insert, it depends on the shoe sole and the insert. Shoe deformation can only take place at some predetermined positions.

  In the technique described in this prior patent, the tension or pressure acting along the longitudinal axis of the rigid insert is large enough to change the position of the insert and consequently the shape of the shoe. The shoe sole cannot be stably maintained in a preferable deformed state for a long time.

It is an object of the present invention to provide a shoe having a sole that can be sized to the sole of a shoe user and to overcome the above-mentioned drawbacks, and in particular to maintain the shape in a deformed state. Pressure that is easy to manufacture and assemble, and that can adjust the deformation of the sole so that the sole fits in an optimal manner to the specific size of the sole of the user's sole, and encourages or reduces the deformation It is to provide a method for adjusting the size of the sole of a shoe having means to ensure that its deformation is maintained over time even if it is applied.

  These objects and other objects apparent to those skilled in the art are achieved by a shoe and method according to the features of the independent claims.

  The invention will become more apparent from the accompanying drawings provided for non-limiting examples.

  Referring to FIG. 1, the shoe of the present invention will be apparent to those skilled in the art, but for example, an upper portion secured to the sole 2 in a conventional manner such as sewing or gluing, i. 1 and an insole 3 which is inserted into the toe on the sole 2. This toe may be made of any material suitable for the above purpose, in particular an at least partially elastic material of the type normally used in the footwear field.

  As an advantage, the bottom of the toe is fixed to the sole with an insert 1B made of a material having at least some elasticity so that the size of the toe, in particular its width, does not change with deformation. It is in a position close to the peripheral part.

  The shoe sole 2 shown in the example includes a combination of two parts connected to each other, that is, an intermediate part 4 having a lower surface 4A that partially contacts the ground, and a plurality of members that contact the ground. It is two parts of the outer part 5 which has and functions as the collar 5A and the collar 5B. This outer part is well known to those skilled in the art and is formed of many different parts, for example, the heel part or the front part of the foot, which is the outer part of the foot on the ground. It acts to weaken the impact of mounting.

  Referring to FIG. 1, the middle part 4 of the shoe sole 2 includes several parts. That is, the deformed portions 6A and 6B and the substantially non-deformed portions 7A, B, and C. Due to the deformation of the deformation portions 6A and 6B, the size of the shoe sole can be changed at least partially, and the size of the shoe sole can be adjusted to the size of the sole of the shoe user. .

  In this specification, it is noted that the definitions of deformed and non-deformable materials are understood in the sense that when a material is not deformed, it is undeformed when subjected to a force equivalent to the force that deforms the deformable material. Should.

  According to a preferred embodiment, the deformable portion 6A-B is formed of a plastic resin material, for example, an elastomer, in particular, natural rubber, synthetic rubber, vulcanized rubber or injection-molded thermoplastic resin in order to achieve its purpose. On the other hand, the non-deformed portions 7A-C of the intermediate shoe sole 4 are formed of leather.

  It is preferred that the deformable portions 6A-B have coplanar protrusions 8 (4A-M) interconnected by an intermediate collar 9 that can take on the various profiles shown in FIGS. 4A-M. . In some embodiments (4A-G), the projecting portion 8 of the deforming portion is fitted to a recess 10 having the same shape and size as the projecting portion 8 and provided in the non-deforming portion 7A-C. As a result, the protrusion 8 and the upper surface 4B of the middle part 4 of the shoe sole are positioned substantially on the same plane. The deforming portion 6A-B and the non-deforming portion 7A-C are preferably a well-known method used by specialization in the art such as forming, bonding, and sewing the deforming portion 6A-B to the non-deforming portion 7A-C. By attaching, they are firmly connected to each other.

  In another embodiment (FIGS. 4H-M), the protrusion 8 and all deformations 9 are integrated with the lower part 5 of the shoe sole in contact with the ground. In this case, the sole portion 5 and the deformed portion are formed of the same material or different materials, and are usually molded or injected so that the sole portion 5 is in contact with the ground in a higher density than the material of the portion 4, for example. It is formed by molding. In addition, the protrusion 8A can be fixed to the leather sole 4 by a well-known method such as adhesion, sewing, integral molding, injection molding, or the like. The leather shoe sole 4 has the same base (not shown) as the above-described base 10 below the base 10. In addition, the protrusion may be provided below the portion 5B and fixed to the leather shoe sole 4 together with the portion 5B.

  As shown in FIGS. 4A-M, for example, the flange 9 has two mutual shapes as shown in FIGS. 4A, B, M, as shown in FIGS. 4A, B, M. V-shaped (Fig. 4C) inclined to the center, a shape indicated by a plurality of U's that are larger and alternately arranged at the center of the heel, and a shape represented by U's of the same elongated shape that are alternately arranged (Fig. 4D) A shape formed by continuously arranging a plurality of Us having the same shape with a long and narrow width (FIG. 4E), a plurality of U shapes (FIG. 4L) whose end portions are combined and contracted in an undeformed state, A shape in which wide U's are continuously arranged in a state where they are alternately arranged with narrow U's (FIG. 4F), a shape in which V of various sizes are alternately arranged in succession, and a side portion. The shape of the part (FIGS. 4H, I) which has a long central part and is T-shaped in the undeformed state and U-shaped in the deformed state Various shapes etc. can take.

  In order to more suitably fit the deformed portion in a specific shape, the wall portion of the base 10 provided on the shoe sole 4 for the purpose of fitting the deformed portion is the wall portion of each heel portion in the non-deformed state. The upper portion 10A (FIG. 4C) or the lower portion 10B (FIG. 4D) includes inclined wall portions that approach each other so as to act as an abutment. Advantageously, since the surfaces of these abutments are not connected to each other, the deformation of the heel can be facilitated. When the inclined wall portion 10B is approached downward, the surface of the heel that contacts the ground is limited, while a relatively large ridge portion can be fitted.

  A hook-shaped deformed portion is preferable to a flat deformed portion. In other words, the hook-shaped deformed portion has a continuous closed cross-sectional portion such as a rectangle, and in this respect, the force required to widen the deformed portion due to the hook shape is large. It is smaller than the force acting when the deformed portion is flat. Therefore, there is less risk of the deformed portion being destroyed or leaving the non-deformed portion when exposed to the tension for deformation.

  It is also advantageous that the deformed part has a continuous long shape and is arranged symmetrically about the longitudinal axis S of the shoe sole. This is because the arrangement and shape ensure further improvement in resistance of the deformed portion and more uniform deformation of the shoe sole. This is limited to shoes in which the end portion 13 of the deformed heel portion is open at the side end of the shoe sole.

  In addition to various transverse shapes, the above-described deformable portion can be variously changed in length or shape extending in the longitudinal direction and the position of the deformable portion.

  FIG. 1 shows a first deforming portion 6A having a U-shape extending from a U-shaped end portion 13 located in the arch portion of the shoe sole to the front portion of the foot along the outer edge of the shoe sole, A slightly arcuate second deforming portion 6B extending across the longitudinal axis S of the shoe sole at a portion is shown. 6A of 1st deformation | transformation parts accept | permit the deformation | transformation of a periphery, ie, the breadth of the front part of a shoe sole, while a 2nd deformation | transformation part accepts expansion | extension of a shoe sole.

  FIG. 2A shows a first deformed portion 16A having a closed shape substantially equal to the circumference of the sole along the outer edge of the sole and disposed at the outer end of the sole. With this shape, every part of the sole can be expanded. In order to make this expansion more suitable, a second portion that is the same as the first closed portion 16A of FIG.

  FIG. 2B shows a pair of deformed portions 26A that are arranged symmetrically with respect to the longitudinal axis S of the sole at the front portion of the foot and have end portions 26C that are ends at the toe portion and the arch portion of the sole. The 2nd part 26B provided in the arch part in the state straddling the said axis | shaft and arrange | positioned at the wave form is shown.

  FIG. 2C shows a first deforming portion 36A extending from the toe portion to the heel portion in a state of substantially overlapping with the longitudinal axis S of the shoe sole, and a second portion 36B provided on the arch portion straddling the vertical axis. Indicates.

  FIG. 2D is a pair of crumbled M shapes extending symmetrically about the longitudinal axis S of the sole at the front part of the foot and having ends 46C ending at the toe part of the shoe sole and the arch part. 46A, and a second long V-shaped portion 46B whose apex is disposed at the heel portion and whose end ends at the arch portion.

  FIG. 2E shows the only deformation 56A that corresponds to the portion 6A shown in FIG.

  FIG. 2F shows that the heel part extends from the heel part to the arch part in a state of being overlapped with the ordinate S, is symmetrical with respect to the ordinate S at the arch part, and extends along the outer periphery of the shoe sole. A deformed portion 66A having an arcuate arm portion 66B that is divided and extended so as to merge again.

  FIG. 2G shows a first portion 76A that substantially matches the portion 16A of FIG. 2A and a central portion 76B that is substantially identical to the portion 6B of FIG. 1 except that it is connected to the portion 76A.

  FIG. 2H shows a plurality of deformations 86A, B that form a grid that is parallel and perpendicular to the longitudinal axis of the sole.

  FIGS. 3A and 3B show an arcuate deformed portion 96 </ b> A arranged symmetrically with respect to the longitudinal axis of the sole in the front portion of the foot, along with the ends 13 at the arch and toe portions.

  In order to deform the shoe, the force F (FIG. 3B) needs to act in a direction substantially perpendicular to the shoe in order to widen and / or stretch or shrink the circumference of the sole. That is, the thickness of the deformed portion is, for example, about F1 to F2 (FIGS. 3A and 3B) as shown in FIGS. 3A and 3B. According to a variant according to the invention, the width or length is 1-10 mm.

  In order to maintain the shoe sole of the present invention in the desired deformed state, the shoe insole 3 has one or more suitably sized rigid inserts 14. These inserts preferably have a flat portion 14A for wrapping the sole, and a side surface portion 14b extending from the flat portion 14 along the side surface of the toe. The flat portion 14A has a lattice shape due to the openings C, and the insert 14 is preferably formed of, for example, a metal having a similar property of high rigidity or a rigid material that does not deform, such as plasticity. The insert is preferably firmly fixed to the lower surface of the insole 3 by gluing, injection molding or integral molding.

  With the insert shown in FIG. 1, two effects can be obtained by inserting the insole 3 into the shoe. Due to the presence of the rigid insert 14, the front part of the foot of the shoe sole 4 is deformed so as to maintain a width L 1 that is equal to the width L 2 of the insert.

  Depending on the deformation of the shoe sole part, inserts with larger or smaller sizes and suitable shapes are used. For example, the cruciform insert 24, shown in phantom in FIG. 2C, can deform the shoe sole to change both length and width in the area in front of the foot, and the deformation is maintained.

  If the arm portion 24A is removed and only the arm portion 24B is left, only deformation that changes the length is possible. An insert that is indicated by a broken line in FIG. 2D and denoted by reference numeral 34 can be modified to change the width of only the ridge region.

  In order to prevent the insole 3 from rising from the sole 2 by the rigid insert 14, the insert 14 has means 18 for securing the insert 14 in a removable state from the sole. Therefore, the insert 14 is provided in a member 5B (indicated by an arrow A) of the outer portion of the shoe sole, for example, protruding from the lower surface thereof and attached to the outside and penetrating the hole 20 provided in the shoe sole 4. The screw 19 is screwed into the screw hole 5C.

  In accordance with the present invention, for each size of the shoe of the invention, the purchaser can utilize a plurality of different insoles, each with various rigid inserts. For example, if a purchaser purchases a size 8 shoe, many insoles will have a size if they do not use various rigid inserts that fit the sole, such as wide, normal or narrow. All 8 shoes will be worn out.

  After the insole is selected that best fits the buyer's foot, the insole is inserted into the shoe and the rigid insert is attached to the insole, so that the shoe sole deforms and becomes the size of the insole. This deformation is maintained during use of the fitted shoe.

  Therefore, according to the present invention, for a shoe of the same size, the purchaser can adapt all or only a specific portion of the sole within a range of ± 0.5 of the shoe size.

  It should be noted that the shape and size of the toe 1 can be modified at least in part by the collar 14B (FIG. 1) of the rigid insert 14, and in particular, the part or insertion of the collar 14B. The thing 1B is a point comprised with the member which is at least partially elastic. In this respect, when the insole 3 is inserted, not only the extension of the shoe sole tailored to the individual, but also the extension of the toe leather is achieved by the heel part 14B.

  Finally, it should be noted that the present invention has been described by way of example only, and that numerous modifications are possible within the inventive concept. For example, the substantially undeformed leather part 7A-C may be replaced with a plastic member, and the shoe sole 2 may be integrally formed of a plastic material. Moreover, you may form the deformation | transformation part 6A-6B integrated with member 5A-5B and said part 7A-C by normal shaping | molding and / or injection molding, for example.
