  Hereinafter, each embodiment of the moon core etc. concerning the present invention is explained in full detail based on a drawing. In each embodiment, the moon core is applied to men's leather shoes.

  FIGS. 1-23 has shown 1st Embodiment of the moon core etc. which concern on this invention, and the moon core 11 which concerns on the said embodiment is the side of the heel 1b of the shoe 1, as shown in FIG. The leather 12 is interposed between the front leather 2 and the back leather 3 in the rear part of the shoe so as to surround the part, and as shown in FIG. The impregnated paper 13 obtained by impregnating the base paper with the resin is bonded with a predetermined solvent-based adhesive 14 so that the entire impregnated paper 13 is inside as shown in FIG. A curve is formed along the side of the flange 1b.

  Here, as shown in FIG. 19, the moon-shaped core 11 is set to a thickness of about 2.2 mm, and the leather 12 and the impregnated paper 13 are attached to each thickness of 1.1 mm. Are combined. Thereby, in the moon core 11 which concerns on this embodiment, compared with the conventional moon core which uses the leather of thickness 2.2mm alone, the weight of the leather is about half, and Since the impregnated paper 13 is sufficiently light compared to leather, it is significantly lighter than the conventional lunar core.

  As shown in FIGS. 19 and 21, the lunar core 11 has the entire peripheral edge portion 11b so that the cross section is tapered, and the impregnated paper 13 is disposed only in the central portion 11a. The peripheral edge portion 11b is composed only of the leather 12 that is thinly sown by the above-described squeezing process. Further, the moon core 11 is the side 15 a of the both ends 15, 16 a and the lower side of the moon core 11 at both ends of the longitudinal one end 15 and the other end 16. The angle between the side 18a of the other side portion 18 in the longitudinal direction described later is an acute angle, that is, the sides 15a and 16a of the both end portions 15 and 16 are inclined upward toward the shoe rear side. Is formed.

  The impregnated paper 13 is a base paper made of wood pulp alone, a base paper mixed with wood pulp and flesh, or a base paper mixed with wood pulp, flesh and synthetic fibers, so-called SBR synthetic latex or acrylic. The base paper is impregnated with the resin by dipping in a resin agent containing the resin, and dried. The component ratio of the impregnated paper 13 is 15% to 40% of the resin with respect to 85% to 60% of the wood pulp.

  Here, the scraps are shaving scraps that are discarded as scraps in the field of shoes, bags, and other leather materials, and the shaving scraps are pulverized by a pulverizer to be broken into fibers. It is a fiber (so-called collagen fiber). In addition, although the mixing ratio of this leather waste may be any as long as it is within the range of 10% to 90% of the wood pulp ratio, it is desirable that the ratio of wood pulp to 50% is good.

  Moreover, also about the said synthetic fiber, the thing discarded as an end material is cut | disconnected and used similarly to the said skin waste. In addition, about the mixing ratio of this synthetic fiber, 15% of wood pulp and flakes ratio is made into an upper limit, Preferably 5%-8% of wood pulp and flakes ratio is favorable.

  Hereinafter, the manufacturing method of the lunar wick 11 according to the present invention and the manufacturing apparatus of the lunar wick 11 according to the present invention used in the rolling process described later in the production will be described with reference to FIGS. To do.

  Here, first, a method for manufacturing the moon core 11 will be described. As shown in FIG. 1, the moon core 11 is a cutting (unplugging) process S1 as a first process and a second process. It is manufactured through four steps including a bonding (adhesion) step S2, a third step (slicing) step S3, and a fourth step (bending (molding) step S4).

  That is, in the cutting step S1, which is the first step, as shown in FIGS. 2 and 3, leather 12 obtained by pruning rawhide and impregnated paper 13 obtained by impregnating a base paper with resin are respectively provided. Cutting (punching) is performed with the same punching die 21 using a hydraulic cutting machine (die cutting machine) called a clicker (not shown). The cutting die 21 is provided with a blade portion at least at the entire circumference of one end portion thereof, and the cutting die 21 is brought into contact with the leather 12 or the impregnated paper 13 to be extracted so that the cutting die 21 is By pushing with a pressing force by a clicker, each of the punching objects is punched into the shape of the punching die 21. Here, the cutting of the leather 12 and the impregnated paper 13 will be described in detail. First, the cutting of the leather 12 is cut in half from the back to a thickness of 1.1 mm as shown in FIG. Place the leather 12 that has been chopped on the clicker table, punch the punching die 21 one by one in the direction of the arrow while identifying the part that can be used as the lunar core 11 while avoiding the scratched part. To do. Since the punched leather 12 has different qualities depending on the parts such as the shoulder and the stomach, the punched leather 12 is classified into the same quality. On the other hand, as shown in FIG. 3, the impregnated paper 13 is cut by stacking five sheets of impregnated paper 13 impregnated with the resin on a standardized paper having a thickness of 1.1 mm and aligning the corners. After that, one corner is fixed with a staple 22 or the like, and the punching die 21 is pushed in the direction of the arrow as in the case of the leather 12, thereby punching five pieces at predetermined intervals. Thus, in the cutting of the leather 12, one sheet of leather 12 is obtained for each cutting, whereas in the cutting of the impregnated paper 13, five sheets of impregnated paper 13 are obtained for each cutting. In addition, since it is not necessary to identify an appropriate part or to sort it into the same quality as the cutting of the leather 12, the cutting is performed at least five times more efficiently than the cutting of the leather 12. It can be performed.

Subsequently, in the bonding step S2 which is the second step, the cut impregnated paper 13 is taken one by one, and this is applied to a coating machine called a gravure coater, so that the leather 12 of the impregnated paper 13 and The adhesive 14 is applied to the outer side surface 13a which is a bonding surface. Then, as shown in FIG. 4, the leather 12 cut into the same size is placed on the impregnated paper 13 to which the adhesive 14 is applied, thereby bonding the both 12 and 13 together. By repeating such operations, a predetermined number of the lumber cores 11 formed by polymerizing the leather 12 on the impregnated paper 13 are stacked, and these are applied to a press machine until the adhesive 14 is dried with a load of about 1 t / cm ^2. By pressurizing, the leather 12 and the impregnated paper 13 are pressure-bonded to each moon core 11.

  Next, in the sowing step S3, which is the third step, first, the moon core 11 formed by laminating the leather 12 and the impregnated paper 13 in the bonding step is provided with a band-shaped blade called a band knife. 19, the peripheral portion 11b of the surface on the impregnated paper 13 side is processed so that the impregnated paper 13 remains in the central portion 11a as shown in FIG. At this time, the peripheral edge portion 11b of the moon core 11 is divided into four regions including one end portion 15 and the other end portion 16 in the longitudinal direction and one side portion 17 and the other side portion 18 in the longitudinal direction. Each of the regions is separated and processed by dividing the peripheral edge 11b of the moon core 11 into four times. That is, as the first combing process, after forming the first slice portion 15b in the one end part 15 by combing the longitudinal one end part 15 of the moon core 11, as the second combing process, A second slice portion 16b is formed in the other end portion 16 by subjecting the other end portion 16 to be formed, and then, as a third punching portion, one side portion in the longitudinal direction which is an upper portion of the moon core 11 After the third slice portion 17b is formed on the one side portion 17 by rolling 17, the other side in the longitudinal direction, which is the opposite side and the lower side portion of the lunar core 11, as the fourth winding processing A fourth slice portion 18b is formed on the other side portion 18 by rolling the portion 18.

  In this way, the peripheral edge 11b of the lunar core 11 is divided into four regions each consisting of the longitudinal end portions 15 and 16 and the longitudinal side portions 17 and 18 and separately processed, so that the moon As shown in FIGS. 19 and 20, the core 11 includes first and second slice portions 15 b and 16 b at the end portions 15 and 16 in the longitudinal direction and third and third portions at the side portions 17 and 18 in the longitudinal direction. By intersecting the four slice portions 17b and 18b, an inner corner portion 11d corresponding to the outer corner portion 11c, which is the four corner portions of the lunar core 11 having a substantially trapezoidal shape, is formed in the central portion 11a. In addition, a ridge portion 11e that is a ridge line continuous from each inner corner portion 11d toward each outer corner portion 11c is formed. Then, the lunar core 11 so-rolled in this way becomes so-called waist by forming the inner corner portions 11d and the ridge portion 11e continuous therewith, and a desired rigidity is ensured. ing. In other words, the inner corner portion 11d and the ridge portion 11e continuing to the inner corner portion 11d serve as so-called reinforcing ribs, so that the rigidity is secured in the lunar core 11 after the rolling process, thereby providing a resilient restoration property. Can be obtained.

  Note that, when performing each of the above-described combing processes, the first and second combing processes have a relatively large combing width as compared with the third and fourth combing processes, and thus a relatively large first one provided with a band knife. While using the slicer 30 (see FIG. 5), the third and fourth milling processes are relatively small compared to the third and fourth milling processes. A second slicer 60 called an edge cutter is used (see FIG. 14). In addition, the structure of both these facilities is demonstrated in detail later.

Finally, in the bending step S4 which is the fourth step, the lunar core 11 which has been subjected to the above-described winding process as shown in FIG. 19 is used as a pair of male mold and female mold set in a predetermined molding machine not shown. 22 and pressurizing with a load of about 1 t / cm ² by this molding machine, and then bending (molding) the finished winding process into a curved state as shown in FIG. This completes the lunar core 11.

  Then, the commercialized lunar core 11 is then inserted into a so-called upper 1a where the shoe sole 1e is not attached after being immersed in water and left for a predetermined time in a shoe factory, that is, after the curing operation. Then, a predetermined adhesive is applied between the front leather 2 and the back leather 3 of the upper 1a and the moon core 11, so that the upper leather 2 and the back leather 3 are bonded and fixed via the adhesive. (See FIG. 23). Here, according to the moon-shaped core 11 according to the present embodiment, the thickness of the leather 12 can be reduced by the thickness of the impregnated paper 13, and the thickness of the leather 12 is reduced. The time required for drying after dipping the moon core 11 in water at a shoe factory, that is, the time for curing the moon core 11 can be shortened. Thereby, it becomes possible to shorten the occupation time of the shoe type | mold concerning manufacture of one shoe, and it will be used for the improvement of productivity of shoes. Further, since the impregnated paper 13 is bonded to the leather 12, the leather 12 is pulled by the impregnated paper 13 when the moon-shaped core 11 is dried, so that the leather 12 is not greatly contracted. In other words, it becomes possible to reduce the variation in the shrinkage of the leather 12 when the moon core 11 is dried, and as a result, the quality of each product of the moon core 11 can be made almost uniform. It becomes.

  Hereinafter, the first and second slicers 30 and 60 used for the processing of the lunar core 11 will be described with reference to FIGS.

  Specific procedures (methods) of the winding process for the respective regions of the one end 15 and the other end 16 in the longitudinal direction in the peripheral edge 11b of the moon core 11 performed using the first slicer 30 configured as described above. This will be described with reference to FIGS.

In the case of performing the cutting process on the region of the longitudinal end portion 15 of the moon core 11, first, the first adjustment block 47 is moved to the right by moving the first adjustment rod 47 clockwise. By rotating the second adjustment rod 50 counterclockwise, the second adjustment block 51 is moved backward in the right direction, so that the roller support member 41 is inclined to the left as shown in FIG. Is adjusted to adjust the inclination θ ₁ of the driven roller 33 (see FIG. 9), and the winding width required for the lunar core 11, that is, the winding width W1 of the first slice portion 15b is set (see FIG. 19).

  Thereafter, the moon core 11 is placed in the input space 35a of the work table 35 with the surface on the impregnated paper 13 side down, and the side 15a of the longitudinal end portion 15 is operated as shown in FIG. In the state where it abuts on the first guide 53 disposed on the left side in the drawing in the table 35, the moon core 11 is pushed out to the positions of the rollers 32 and 33 along the first guide 53. Then, the moon-shaped core 11 is sent out toward the band knife 31 so as to be pulled in by the rollers 32 and 33, and at this time, the one end 15 of the driven roller 33 is connected to the band knife 31 by the one end 33 a. The first slice portion 15b corresponding to the set width W1 is formed in the one end portion 15 of the moon core 11 by being sent out by the rollers 32 and 33 while being pressed against the blade portion 31a. Then, it is discharged to a discharge space 35b behind the work table 35.

On the other hand, in the case where the region of the other end 16 in the longitudinal direction of the lunar core 11 is to be subjected to a boring process, first, the first adjustment block 48 is turned counterclockwise by rotating the first adjustment rod 47 counterclockwise. While moving backward, the second adjustment block 50 is rotated clockwise to move the second adjustment block 51 to the left, so that the roller support member 41 is inclined downward as shown in FIG. By adjusting the inclination, the inclination θ ₁ of the driven roller 33 is adjusted (see FIG. 9), and the winding width required for the moon core 11, that is, the winding width W 2 of the second slice portion 16 b is set (see FIG. 19). ).

  Thereafter, the moon core 11 is placed in the input space 35a of the work table 35 with the surface on the impregnated paper 13 side down, and the side 16a of the other end 16 in the longitudinal direction is placed as shown in FIG. The work table 35 is thrown in along with the second guide 54 disposed on the right side in the drawing. Then, this moon-shaped core 11 is sent out by the rollers 32 and 33 in a state where the other end 16 is pressed against the blade 31a of the band knife 31 by the other end 33b of the driven roller 33. The second slice portion 16b corresponding to the set width W2 is formed at the other end portion 16 of the core 11, and is discharged into the discharge space 35b behind the work table 35.

Next, the second slicer 60 will be described. As shown in FIGS. 14 to 18, the second slicer 60 has a blade portion 61 a continuous in the longitudinal direction at least at one end portion in the width direction (end-side end portion). A substantially annular band knife 61 that rotates based on the driving force of an electric motor (not shown), and is tangential to the blade portion 61a of the band knife 61 and directly above the blade portion 61a of the band knife 61. A driven roller 62 that feeds the moon core 11 while pressing the moon core 11 against the blade portion 61a of the band knife 61, and an inclination θ _{2 of the} driven roller 62. A width adjustment means 63 for adjusting the widths W3 and W4 of the third and fourth slice portions 17b and 18b at the peripheral edge portion 11b of the moon core 11 by changing ing.

  The band knife 61 is continuously driven in the longitudinal direction by being rotationally driven by the electric motor through a pulley (not shown) accommodated in the housing 64. The band knife 61 is also provided with a blade portion 61a over the entire circumference of the front end portion in the X-axis direction in FIG. 14 in the width direction. As shown in FIGS. 11 is moved along the X-axis direction of FIG. 14, and the third and fourth slice portions 17 b and 18 b are placed on the longitudinal side portions 17 and 18 on the surface of the impregnated paper 13 facing the blade portion 61 a. It comes to form.

  The follower roller 62 has a cylindrical shape with a different diameter in the middle in the axial direction, and is provided at the tip of an arm 65 extending in an inverted concave shape in the Z-axis direction in FIG. The roller support mechanism 66 is rotatably supported, and the inclination θ2 is changed by changing the inclination of a roller support member 67, which will be described later, constituting the roller support mechanism 66. Here, this inclination θ2 represents the inclination of the axis Q of the driven roller 62 with respect to the tangent N of the band knife 61 parallel to the horizontal upper surface 64a of the housing 64, as shown in FIG. The gap C2 between the driven roller 62 and the band knife 61 changes depending on the inclination θ2 of the driven roller 62, and a range in which the gap C2 is smaller than the basic thickness width of the moon core 11 is each It corresponds to the slice portions 17b and 18b, and the gap C2 in the range is set to the thickness width of the moon core 11 after the sawing. That is, the driven roller 62 presses the moon core 11 against the blade portion 61a of the band knife 61 in a range corresponding to each of the winding widths W3 and W4, so that the winding process is performed in the range. .

  As shown in FIGS. 14 and 15, the roller width adjusting means 63 is a roller support mechanism that rotatably supports the driven roller 62 via a roller support member 67 that is rotatably provided at the tip of the arm 65. 66, and a roller inclination varying mechanism 68 that changes the inclination θ2 of the driven roller 62 via an adjustment rod 70 described later linked to the roller support mechanism 66.

  The roller support member 67 is configured to support both end portions in the axial direction of the driven roller 62 by both opposing end portions of the support portion 67a formed in an inverted concave shape, and is described later as being inserted into the support portion 67a. The pin member 69 is rotatably supported at the tip of the arm 65.

The roller tilting variable mechanism 68 includes a pin member 69 that is inserted into a corner of one end in the longitudinal direction of the support portion 67a of the roller support member 67, and one end in the longitudinal direction of the support 67a in the Z-axis direction in FIG. The arm portion 67b extending toward the front end of the arm 65 and the arm 65 is screwed along the Y-axis direction in FIG. 15, and one end of the arm portion 67b is pressed in the negative Y-axis direction in FIG. Thus, an adjustment rod 70 that changes the inclination of the roller support member 67 via the arm portion 67b, and an adjustment rod 70 that is disposed on the distal end side of the arm 65 so as to be in elastic contact with the other side surface of the arm portion 67b. 15 is a leaf spring member 71 that presses the arm portion 67b in the positive direction of the Y axis in FIG. 15, which is the distal end side of the adjustment rod 70. The adjustment rod 70 is rotated to rotate the protrusion amount L on the distal end side of the adjustment rod 70. Adjust the arm 6 b rotational position of being changed, thereby, and can be changed inclination theta ₂ of the driven roller 62 via the roller support member 67.

  Specific procedures (methods) of the winding process for each region of the one side 17 and the other side 18 in the longitudinal direction of the peripheral edge 11b of the moon core 11 performed by using the second slicer 60 configured as described above. ) Will be described with reference to FIGS.

In the case where the region of the one side portion 17 in the longitudinal direction of the moon core 11 is to be subjected to winding, first, the inclination θ of the driven roller 62 is adjusted by rotating the adjustment rod 70 to adjust the protrusion amount L on the tip side. ₂ is adjusted (see FIG. 16), and the width W3 of the third slice portion 17b required by the lunar core 11 is set (see FIG. 19).

  Thereafter, the side 17a of one side 17 in the longitudinal direction was disposed on the horizontal upper surface 64a of the housing 64 with the moon core 11 faced on the impregnated paper 13 side as shown in FIG. Push along guide 72. Then, this moon-shaped core 11 is sent out in a state where the one side portion 17 is pressed against the blade portion 61a of the band knife 61 by the one end portion 62a of the driven roller 62 as the driven roller 62 rotates. The third slice portion 17b corresponding to the set width W3 is formed on the entire one side portion 17 of the moon core 11.

Even when the region of the other side portion 18 in the longitudinal direction of the moon core 11 is to be rolled, the adjustment rod 70 is rotated so that the protruding amount L on the distal end side is set in the same manner as the one side portion 17 side. By adjusting, the inclination θ ₂ of the driven roller 62 is adjusted (see FIG. 16), and the width W4 of the fourth slice portion 18b required by the moon core 11 is set (see FIG. 19).

  Thereafter, the moon core 11 is pushed along the guide 72 along the side 18a of the other side 18 in the longitudinal direction as shown in FIG. 18 with the surface on the impregnated paper 13 side down. Then, this moon-shaped core 11 is sent out in a state where the other side portion 18 is pressed against the blade portion 61a of the band knife 61 by the one end portion 62a of the driven roller 62 as the driven roller 62 rotates. The fourth slice portion 18b corresponding to the set width W4 is formed on the entire other side portion 18 of the core 11.

  Thus, by using each of the slicers 30 and 60, each of the slice portions 15b to 18b can be separately wound on the peripheral edge portion 11b of the lunar core 11, so that each of the inner corner portions 11d can be processed. It becomes possible to form the ridge part 11e continuous with this, and it is used for ensuring the rigidity and the restoring property of the lunar core 11 after the sowing process.

  In particular, when the both end portions 15 and 16 of the lunar core 11 are to be machined, the first slicer 30 is not suitable for a punching machine that is a small slicer such as the second slicer 60. Since a relatively large slicer such as the above must be used, the large slicer is configured to process the entire periphery 11b at once using a mold as described above. Each slice part 15b-18b cannot be separately wound and processed. However, according to the first slicer 30 according to this embodiment, the pair of tilt variable mechanisms 43 and 44 can be independently operated in the winding width adjusting mechanism 34, and the roller support member 41 can be tilted. As a result, the both end portions 15 and 16 of the lunar core 11 are subjected to separate machining.

It should be noted that when the both end portions 15 and 16 of the lunar core 11 are to be machined using a large slicer such as the first slicer 30, the axial intermediate portion such as the driven roller 62 used in the second slicer 60 is used. By using a roller with a constricted portion, the both end portions 15 and 16 can be separately wound. In this case, depending on the winding widths W1 and W2 of the slice portions 15b and 16b, respectively. Therefore, production management becomes complicated and the manufacturing cost increases. However, according to the first slicer 30 according to the present embodiment, as the structure in which the driven roller 33 is inclined, the widths W1 and W2 of the slice portions 15b and 16b are set by the inclination θ ₁ of the driven roller 33. Therefore, it is possible to perform the winding process for any width by only the driven roller 33 having a substantially uniform outer diameter in the axial direction. That is, according to the first slicer 30 according to the present embodiment, it is not necessary to prepare a driven roller corresponding to the width of the roller for the width of the roller, which facilitates production management and reduces the manufacturing cost. It will also be used for cost reduction.

Moreover, according to the first slicer 30, the inclination θ ₁ of the driven roller 33 can be changed only by rotating the adjustment rods 47 and 50, so that the width W 1 of the slice portions 15 b and 16 b can be changed. The adjustment work of W2 can be performed as easily as possible, and the adjustment work man-hour is reduced. Thereby, it can contribute to the further reduction of the manufacturing cost which concerns on the moon-shaped core 11. FIG.

  As described above, according to the present embodiment, the first and second slicers 30 and 60 are used to perform the winding process according to the present embodiment, that is, the respective slice portions 15b to 18b are separately processed. Accordingly, the inner corner portions 11d and the ridge portion 11e continuous therewith can be formed on the inner surface of the moon core 11. As a result, the lunar core 11 after the whispering can be provided with a waist, and sufficient rigidity and restorability can be secured in the lunar core 11 after the whispering.

  FIG. 24 shows a modification of the moon core 11 according to the first embodiment. The basic configuration of the moon core 81 according to the present modification is the same as that of the moon core 11 according to the first embodiment. Therefore, for convenience of explanation, the moon according to the first embodiment will be described below. About the same structure as the shape core 11, the same code | symbol is attached | subjected and the description is abbreviate | omitted, and only a different point from the moon shape core 11 which concerns on the said 1st Embodiment is demonstrated.

  That is, the moon-shaped core 81 according to the present modification is obtained by applying thermosetting adhesives 82 and 82 to both the front and back surfaces of the moon-shaped core 11 according to the above-described embodiment and drying it. The adhesive application work in the shoe factory, which is bonded to the upper 1a in the shoe factory through the adhesives 82, 82, is unnecessary.

  And in manufacturing the moon core 81 which concerns on this embodiment, the adhesive agent which is a 5th process with respect to the moon core 11 which concerns on the said 1st Embodiment obtained through the said 1st-4th process. In the coating step, the adhesive 82, 82 is applied to both the front and back surfaces, and then dried to complete the manufacture of the moon core 81. The product-made lunar core 81 is then inserted between the front leather 2 and the back leather 3 of the upper 1a in a shoe factory, and the upper 1a is fitted into a foot-shaped mold. By being heated and pressed at a temperature of about 70 to 90 ° C., the two leathers 2 and 3 are bonded and fixed via the adhesives 82 and 82.

  Thus, according to the moon core 81 according to the present embodiment, since it is molded by heating and pressurizing using a mold, like the moon core 11 according to the first embodiment, There is no need to perform the cumbersome curing operation of immersing in water and then drying it against a shoe mold. For this reason, in the case of the said lunar core 81, compared with the lunar core 11 which concerns on the said 1st Embodiment, shoemaking work can be performed in a shorter time. That is, it becomes possible to greatly improve the efficiency of use of the shoe mold, which is used to further improve the productivity of the shoe.

  Conventionally, the upper 1a is bonded by manually applying an adhesive at a shoe factory as a post-process. However, in the case of the moon core 81 according to this modification, the bonding is performed. Since the agents 82 and 82 are preliminarily applied, the lunar core 81 is inserted between the upper leather 2 and the back leather 3 of the upper 1a, and is heated and pressed with a heating molding machine as it is. Gluing can be performed. That is, according to the moon core 81 according to the present modification, the conventional manual work in the shoemaking process is mechanized, and there is an advantage that the productivity of shoes is further improved.

  25 and 26 show a second embodiment of the moon core according to the present invention, and the shape of the moon core 11 according to the first embodiment is changed. Since the basic configuration of this embodiment is the same as that of the first embodiment, the same components as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted for convenience of description. Only differences from the first embodiment will be described.

  That is, the moon core 111 according to this embodiment is attached to the upper 1a, and the other end 16 in the longitudinal direction disposed on the outside (outside) of the shoe 1 is the moon according to the first embodiment. Similar to the core 11, it is set to be relatively short so as to surround only the vicinity of the heel 1 b, whereas the longitudinal one end side 15 arranged on the inner side (inward) of the shoe 1 is from the heel 1 b. It is set to be relatively long so as to extend to the toe 1d side rather than the arch 1c, and the one end side 15 in the longitudinal direction is configured to be longer than the other end side 16. From such a configuration, not only the vicinity of the heel 1b but also the inside of the foot is surrounded by the moon core 111 from the heel 1b to the toe 1d side of the arch 1c.

  According to the moon core 111 according to the present embodiment configured as described above, the shoe 1 that can be opposed to the foot with a larger area than the other end 16 in the longitudinal direction disposed on the outside of the shoe 1. By forming the longitudinal one end side 15 arranged on the inside so as to extend longer than the other end side 16, it is possible to more effectively limit the movement of the foot within the shoe. As a result, the fatigue of the foot caused by the movement of the foot within the shoe can be more effectively reduced.

  In addition, as in the present embodiment, in order to form the longitudinal one end side 15 so as to extend longer, higher rigidity is required than the lunar core 11 according to the first embodiment. Although it is difficult to ensure sufficient rigidity of the lunar core 111 according to the embodiment depending on the milling process using the mold, the peripheral portion has the first and second slicers 30 and 60 according to the first embodiment. For 11b, it is possible to ensure sufficient rigidity even in the lunar core 111 according to the embodiment by separately slicing and processing the slice portions 15b to 18b, and the movement of the foot in the shoe. Subject to appropriate regulations.

  FIGS. 27 and 28 show a third embodiment of the moon core according to the present invention, in which the shape of the moon core 111 according to the second embodiment is changed. The basic configuration of the moon core 211 according to this embodiment is the same as that of the moon core 111 according to the second embodiment. Therefore, for convenience of explanation, the moon according to the second embodiment will be described below. About the same structure as the shape core 111, the same code | symbol is attached | subjected and the description is abbreviate | omitted, and only a different point from the moon shape core 111 which concerns on the said 2nd Embodiment is demonstrated.

  That is, the moon core 211 according to the present embodiment is attached to the upper 1a, and the longitudinal one end side 15 disposed on the inner side of the shoe 1 is the same as the moon core 111 according to the second embodiment. Further, the other end 16 in the longitudinal direction disposed outside the shoe 1 is also substantially the same length as the one end 15 while being configured to extend from the heel 1b to the toe 1d side rather than the arch 1c. Or it is comprised so that it may extend comparatively long so that it may become about 1-2 cm shorter than the said one end side 15. In other words, when the shoe 1 is worn by the moon-shaped core 211, the inside of the foot is surrounded by the one end side 15 from the heel 1b to the toe 1d side rather than the arch 1c, and the outside is the other end. The side 16 surrounds the ridge 1b to the vicinity of the position corresponding to the arch 1c.

  According to the moon core 211 according to the present embodiment configured as described above, not only the inner side surface of the foot but also the outer side surface of the foot is surrounded from the heel 1b to the vicinity of the position corresponding to the arch 1c. By doing so, it is possible to further restrict the movement of the foot in the shoe as compared with the lunar core 111 according to the second embodiment. On the other hand, the extension of the other end 16 in the longitudinal direction of the lunar core 211 is fastened from the heel 1b to the vicinity of the position corresponding to the arch 1c, so that the comfort of the shoe 1 is unnecessarily increased and the comfort deteriorates. There is no risk of inviting. In other words, according to the moon-shaped core 211, it is possible to restrict the movement of the foot within the shoe to the maximum as long as the rigidity of the shoe 1 does not become too high. As a result, the fatigue of the foot caused by the movement of the foot within the shoe can be minimized.

  In addition, as in the present embodiment, when forming the longitudinal ends 15 and 16 to extend longer, rigidity higher than that of the moon core 111 according to the second embodiment is required, Although sufficient rigidity of the lunar core 211 according to the present embodiment cannot be ensured by the conventional milling, the first and second slicers 30 and 60 according to the first embodiment For the portion 11b, it is possible to ensure sufficient rigidity even in the lunar core 211 according to the embodiment by separately dividing the sliced portions 15b to 18b and separately processing the foot in the shoe. Provided with appropriate restrictions on movement.

  The present invention is not limited to the configuration of each of the above embodiments, and for example, the moon core according to the present invention can be applied to shoes other than men's leather shoes.

  Further, the modified example of the first embodiment can be combined not only with the first embodiment but also with any of the second embodiment or the third embodiment.
