In some embodiments described below, the same or similar components may be denoted by the same reference numerals and description thereof may be omitted. Moreover, in each embodiment, the characteristic component is mainly demonstrated and you may provide the component of other embodiment.

[First embodiment of the present invention]
FIG. 1 shows a perspective view of a shoe 1 according to a first embodiment of the present invention. The left side in FIG. 1 is referred to as the front direction of the shoe or the toe side, and the right side is referred to as the rear direction of the shoe or the heel side. The direction connecting the toes and heels is referred to as the length direction, and the direction perpendicular thereto is referred to as the width direction.

  As shown in FIG. 1, the shoe 1 of this embodiment is a high heel for women, and includes a heel portion 2, a shoe sole portion 3, and an upper portion 4. The heel portion 2 stands substantially perpendicular to the ground contact surface, and the heel portion is positioned higher than the toe portion of the wearer.

  The shoe sole portion 3 is joined to the upper surface of the heel portion 2 on the heel side. The upper portion 4 has a mouth for putting a foot, and is joined to the shoe sole portion 3 at the peripheral portion of the upper surface of the shoe sole portion 3.

  The heel part 2, the shoe sole part 3, and the upper part 4 are formed of a transparent hard member. The hard member may be translucent and may have a metallic or mineral luster. The mineral luster may have a pattern like a marble marble pattern. The hard member may have a color on at least a part of its surface. Alternatively, at least a part of the surface may have iridescent gloss.

  In the present embodiment, the hard member has a plurality of reflection planes (facets) on the surface as shown in FIG. The reflection plane is provided on the entire surface of the upper portion 4, the side surface of the shoe sole portion 3, and the entire surface of the heel portion 2, and receives and reflects light. Since the reflection plane is provided on the entire surface of the shoe, the upper portion 4, the shoe sole portion 3 and the heel portion 2 can be seen continuously, and the upper portion 4, the shoe sole portion 3 and the heel portion 2 are made of different parts. However, it is possible to produce an effect that looks as one. In addition, although the upper part 4 also consists of a hard member in the example of FIG. 1, the upper part 4 may consist of a normal leather or a soft member instead of a hard member. Even in such a case, only the heel portion 2 and the shoe sole portion 3 are made of a hard member, so that a sufficiently beautiful appearance can be obtained. Further, it is possible to provide a reflection plane only on the surface of the heel portion 2. In this case, the heel portion 2 can be emphasized to have a design feature.

  As the hard member, for example, glass, organic glass (acrylic resin, polycarbonate resin, PETG resin (glycol-modified polyethylene terephthalate)) or the like can be used.

  Furthermore, it may be an artificial material mainly composed of acrylic resin or polyester resin such as artificial marble. Furthermore, for example, a soft acrylic whose impact resistance is improved by a polymer obtained by mixing a rubber component (IR) with an acrylic resin (PMMA). Soft acrylic is a flexible thermoplastic acrylic resin.

  Reference numeral 5 denotes a decoration attached to the upper portion 4. The decoration will be described later.

  FIG. 2 shows a side view of the shoe 1 according to the first embodiment of the present invention.

  The shoe 1 has a plurality of decorations 5. In the example of FIG. 2, the bump portion 7 (portion in front of the mouth), the heel portion, and the side portion (side portion of the mouth) of the upper portion 4. Several are attached.

  The decoration 5 may be attached to the heel portion 2 and the shoe sole portion 3. The decoration 5 includes colorless and transparent gemstones such as diamonds, colored gemstones such as sapphire and emerald, pearls or imitations thereof, resin-made ribbons, butterflies and other objects with motifs of animals and plants. The decoration 5 may be formed of a member having the same quality as the hard member. The decoration 5 may be made of the same material as that of the hard member constituting the shoe, and may have a different color.

  The decoration 5 is attached to the upper portion 4 via the attachment portion 12. The attachment portion 12 serves as a pedestal for the decoration 5, and is fixed to the upper portion 4 by adhesion, fusion, or integral molding. The decoration 5 is attached to the attachment portion 12 by fitting, sliding connection, screwing, adhesion, or the like.

  A curved portion 6 that protrudes downward is provided at the front portion of the shoe sole 3. The curved portion 6 is provided at a portion where the vicinity of the metatarsal of the shoe sole 3 contacts in order to stabilize the vicinity of the metatarsal of the wearer. The curved portion 6 prevents slipping of the foot, and the burden on the toe where the body weight is large and the base of the finger and the front of the sole can be reduced.

  A bump part insole 10 made of a flexible material is provided inside the bump part 7 of the upper part 4. The bump portion insole 10 reduces the gap between the upper portion 4 and the wearer's foot, and allows the wearer's foot to move somewhat within the shoe 1 during walking. The bump part insole 10 is preferably made of a transparent material.

  Although the thickness of the shoe sole part 3 is arbitrary, the maximum thickness is 8 mm to 50 mm, preferably 10 mm to 20 mm.

  FIG. 3 is an exploded perspective view of the shoe 1 in which the heel portion 2 and the shoe sole portion 3 are integrally formed.

  In FIG. 3, a base 11 comprising a heel portion 2 and a shoe sole portion 3 is integrally formed, and an upper portion 4 is attached thereto. The integral molding will be described later.

In the example of FIG. 4, the bottom insole 9 is attached to the front of the shoe sole portion 3, and the side insole 13 is attached to the side portion of the upper portion 4. A plurality of insoles can be attached to the inner surfaces of the shoe sole portion 3 and the upper portion 4.

The insole is a flexible member having cushioning properties. For example, a shock-absorbing polymer gel (gel), an elastomer having a hardness of 10 to 30 degrees, silicon rubber, or the like is suitable. Although a part of the surface may have color, it is preferable that the same color as the shoe bottom portion 3 and the upper portion 4, transparency, or mirror surface provides the integrity with the shoe 1.
Here, the hardness is “durometer hardness” which is generally widely used since the measuring machine is simple. "Durometer hardness" is a method of pressing a non-sharp needle (press needle, indenter) into the surface of the object to be measured, measuring the amount of deformation and digitizing it, and using a spring as the force to push the needle . There are two types of durometers, which are standardized in JIS K 6253-3, and there are types A, D, E, and AM.
• Use Type A when the hardness is less than 20 on a Type D durometer.
• If the hardness is less than 20 with a Type A durometer, use Type E.
• If the hardness is greater than 90 with a Type A durometer, use Type D.
• For thin specimens (thickness less than 6.0 mm), use type AM. The hardness in the present specification and claims is a value measured with a durometer of the type selected above.

  The insole may be a foam material such as polyurethane foam. Furthermore, synthetic leather may be used. In order to produce an effect that the inside of the shoe looks transparent, a material in which the member is a transparent body is desirable. On the other hand, when a paint or a pattern is applied to the inner surface of the shoe, it does not necessarily have to be a transparent body.

  The bottom insole 9 and the side insole 13 compensate for a gap generated between the shoe and the wearer's foot, and have a cushioning property so that the wearer's foot is fitted when stationary, and the foot of the wearer's foot when walking. Movement can be tolerated. This will be described with reference to FIG.

By inserting a flathead screwdriver into the gap, the joint surface 39 and the joint surface 39 ′ are separated from each other, and the heel tip portion 33 can be easily removed from the heel base 34.

  By engaging the rotation stopper (convex portion) 40 and the rotation stopper (concave portion) 41, it is possible to prevent the heel tip portion 33 from rotating with respect to the heel base portion 34.

[First production method of the present invention]
FIG. 13 is an explanatory diagram of a shoe manufacturing method according to an embodiment of the present invention.

  The heel part 2, the shoe sole part 3 and the upper part 4 are each integrally formed by injection molding.

  In the injection molding, synthetic resin melted by heating is injected into a cavity of a mold having cavities in the shape of the heel part 2, the shoe sole part 3 and the upper part 4, and then molded. The mold is cooled while pressure is applied until the resin injected into the mold is solidified.

  As described above, when the mold is cooled, a so-called “sink” deformation phenomenon occurs. Sinks may cause dents and holes in the product. For this reason, it is preferable to reduce the deformation as much as possible on the side having the decorative surface.

  On the other hand, in this manufacturing method, cooling is performed from one of the molds. The upper part 4h will be described below as an example.

  In order to form the upper portion 4h, a female die 42 having a concave portion that forms the outer (back side) surface of the upper portion 4h and a male die 43 having a convex portion that forms the inner surface of the upper portion 4h are used. When the female mold 42 and the male mold 43 are combined, a hollow portion having the shape of the upper portion 4h is formed therebetween. After the female mold 42 and the male mold 43 are combined and the synthetic resin is injected into the cavity, the synthetic resin in the upper portion 4 h is cooled from the female mold 42. Thereby, the deformation | transformation of the outer side (back side) surface of the upper part 4h can be decreased. Less deformation on the decorative surface is advantageous for the shoe of the present invention made of a hard material having transparency, color and gloss.

  It is sufficient that the cooling is performed from the mold on the surface side of the product, and is not related to the male and female of the mold. In addition to the upper portion 4h, since the female die is generally the outer surface of the heel portion or the shoe sole portion, cooling is performed from the die that contacts the outer surface.

Also, by increasing the injection pressure, sink marks can be minimized.
For example, in the case of acrylic having a shoe sole thickness of 15 mm, the following conditions may be used.
Tonnage of molding machine (necessary clamping force): 180 tons or more, preferably 250 to 500 tons Injection pressure: 120 MPa or more at the maximum point, preferably 150 to 200 MPa at the maximum point
Injection holding force: about half or more of the above, preferably 70% or more Molding time: 120 seconds or more, preferably 3 to 10 minutes Molding temperature: 200 to 240 ° C.

Molding shrinkage occurs in the process in which the molten resin filled in the cavity is cooled and solidified, and particularly, a resin that crystallizes causes relatively large mold shrinkage. Mold shrinkage is determined by the interaction of many factors. In general, the main factors are as follows.
1 resin temperature, 2 mold temperature, 3 injection pressure, 4 injection speed, 5 injection time, 6 molded product thickness, 7 filler, shape of reinforcing agent, content.

  Here, with respect to the problem of sink caused by the “thickness of the molded product” described in 6 above, it is possible to minimize the sink by increasing the “injection pressure” described in 3 above. Further, by controlling the temperature difference of the “die temperature” in 2 above, a measure is taken to prevent sink marks from appearing on the outer peripheral surface.

  In addition, it can be said that conventional products have been made to keep the wall thickness as constant as possible to eliminate sink marks of the product, and to reduce the wall thickness, shorten the molding time, and increase the strength.

  For this reason, it can be said that the manufacture of products having a large thickness and different thicknesses depending on the parts has been avoided. The product of the present invention aims at a seemingly sculptured product with a thick wall, uneven surface relief, and the like. For example, when the thickness of a molded product made of acrylic resin exceeds 15 mm, cooling time of about 20 minutes is required for cooling. The cooling of each mold is controlled during this cooling time.

  Further, deformation is likely to occur due to internal heat even after taking out the molded product. It is necessary to make a jig so that the deformation does not easily occur and to support it to suppress the deformation, or to hold (placing) the deformation difficult.

  In the shoe sole, the bottom of the outer heel portion 2 of the shoe sole and the bottom near the metatarsal bone are placed on a plane, (1) the toe direction before the vicinity of the metatarsal bone, and (2) the bottom and middle of the heel portion 2 Deformation is suppressed by using a jig provided with a support that suppresses slack in the middle position near the foot bones. Depending on the thickness of the shoe sole 3, only the support (2) may be used. Further, when the width of the heel is thick, the vicinity of the base of the heel tends to swell sideways. For this reason, holding the shoe sole 3 and suspending the heel 2 may prevent the side swell.

  In order to join the heel part 2 and the shoe sole part 3 manufactured by injection molding, a ridge 46 is provided on the upper surface of the heel part 2. The shoe sole portion 3 and the upper portion 4 are joined together at the peripheral edge portion of the ridge 46 and the shoe sole portion 3. The ridge 46 will be further described later.

  Further, in order to join the heel portion 2 and the shoe sole portion 3, a convex portion 44 is provided on the upper surface of the heel portion 2, and a concave portion 45 is provided on the lower surface of the shoe sole portion 3. The heel portion 2 and the shoe sole portion 3 are fitted together with the convex portion 44 and the concave portion 45 and are integrally joined to each other at the joint surface with the convex portion 44 and the concave portion 45.

  FIG. 14A and FIG. 14B show a joining method using the ridge 46 and a modification thereof.

  In the example of FIG. 14A, the ridge 46 is provided on the inner side of the portion of the shoe sole 3 that is joined to the bottom of the upper portion 4. When the shoe sole part 3 and the upper part 4 are combined for joining, the protruding line part 46 comes into contact with the inside of the joining part of the upper part 4. That is, the bottom surface of the joint portion of the upper portion 4 is in contact with the top surface of the shoe bottom portion 3 in abutting state, and the inner side surface of the bottom portion of the joint portion of the upper portion 4 is in contact with the side surface of the ridge 46. Thereby, a joining area becomes large and a firm joining can be obtained.

  In the example of FIG. 14B, the ridge 46 is provided at a position that coincides with the bottom surface of the joint portion of the upper portion 4. The bottom surface of the joint portion of the upper portion 4 has a groove portion 47 that fits with the ridge 46. When the shoe sole portion 3 and the upper portion 4 are combined for joining, the ridge 46 is fitted into the groove 47. When the ridge 46 of the shoe sole 3 and the groove 47 of the upper 4 are fitted to each other, a firm joint can be obtained.

In addition, it is preferable that a junction part is transparent and can use the adhesive agent which has a methylene dichloride as a main component. Further, a cyanoacrylate instantaneous adhesive or a transparent epoxy resin adhesive may be used.
The joining method is not limited to adhesion, and any known joining method such as thermal fusion can be used.

  FIG. 15 shows a shoe 1i in which a heel portion 2 and a shoe sole portion 3 are integrally formed in advance to form a base portion 11i.

  As shown in FIG. 15, the heel portion 2 and the shoe sole portion 3 are integrally formed, and the upper portion 4 is joined to the upper surface thereof. In general, since the base portion 11i is suitable for integral molding, this manufacturing method can simplify the manufacturing process.

  In addition, although the protruding item | line part 46 is provided in the example of FIG. 15, the joining method is not restricted to this, Arbitrary joining methods can be taken.

  Further, in the example of FIG. 15, the ribbon-shaped decoration 5i is provided, but the above-described arbitrary decoration can be provided.

[Second production method of one embodiment of the present invention]
FIG. 16 is a view illustratively showing another shoe manufacturing method of the present invention.

  According to this manufacturing method, the shoe 1j is composed of halved parts 50j 'and 50j "that are vertically divided in the length direction of the shoe, and each is formed by integral molding. Dowels 49 and dowel holes corresponding to the dowels 49 are provided on the joint surfaces 48 of the half parts 50j ′ and 50j ″. At the time of joining, the dowel 49 and the dowel hole are fitted. Thereby, it is difficult to shift the position and the bonding is strong.

  The dowels 49 and the dowel holes may be provided with O-rings or stepped portions, or the joint surfaces may be fitted to each other, and may be joined so as to be fitted to each other.

  In addition, although the recessed part 8j which arrange | positions an insole is provided in each of the half component 50j 'and 50j' ', it cannot be overemphasized that the recessed part 8j also aligns mutually.

[Third production method of one embodiment of the present invention]
Still another shoe manufacturing method according to the present invention is a manufacturing method in which only the heel portion 2 is not halved, the shoe bottom portion and the upper portion are formed as halved parts, and the heel part is incorporated and joined between both halved parts. Is the method.

  FIG. 17 is a view illustratively showing this manufacturing method.

  The shoe 1k is manufactured separately from the halved parts 50k 'and 50k "obtained by vertically cutting the shoe sole portion and the upper portion in the length direction of the shoe, and the heel portion 2k. The integral molding process and the cooling method are as described above.

  The half parts 50k 'and 50k "have a notch 51 at the bottom of the heel. The notch 51 has a T-shaped or inverted triangular notch shape so that the mated counterpart does not come out downward. The notch 51 is provided from the half surface to a predetermined depth. Further, a dowel 49k and a dowel hole corresponding to the dowel 49k are provided on the joint surface between the half parts 50k 'and 50k ".

  On the other hand, on the upper portion of the heel portion 2k, a slide fitting portion 52 whose vertical cross-sectional shape matches the notch shape is provided.

  In this manufacturing method, the half parts 50k ′ and 50k ″ and the heel part 2k are first integrally formed separately, and then the heel part 2k is disposed between the half parts 50k ′ and 50k ″, The slide fitting portion 52 of the portion 2k is incorporated by sliding into the cutout portions 51 of the half parts 50k ′ and 50k ″. After the heel portion 2k is assembled, the half parts 50k 'and 50k "are joined so that the dowels 49k and dowel holes are fitted.

  Thus, the shoe 1k is formed with the heel portion 2k incorporated. Since the cutout portion 51 is provided only from the half surface to a predetermined depth, the slide fitting portion 52 of the heel portion 2k cannot be seen from the outside. Note that the slide fitting portion 52 does not necessarily have a slidable shape. For example, a spherical fitting portion may be used. In this case, the notch may be a hemispherical notch that sandwiches the sphere from both sides.

  FIG. 18 shows a side view of a shoe 1m having a coating 53 on the inner surface.

  In the example of FIG. 18, the entire inner surface of the shoe 1m is glossed. The gloss consists of a glossy material that appears gold, silver, pearl or iridescent. As the glossy material, a paint containing glittering powder called lamé or glitter can be used, and a material that shines in a pearl tone by utilizing multi-layer reflection of light can also be used.

  The gloss material may be applied to the inner side surface of the shoe or may be affixed, or a hologram sheet, a reflection sheet, or the like may be affixed in addition to the above. Moreover, about gold | metal | money and silver, it can also be made to adhere to the inner surface of 1 m of shoes by vapor deposition and sputtering.

  In addition to gloss, colors, patterns, and patterns may be applied to the inner surface of the shoe. Since the shoe body is transparent, gloss, color, pattern, and pattern (hereinafter referred to as gloss) can be visually recognized from the outside of the shoe, and the gloss etc. shines more beautifully by receiving light from the outside.

  Moreover, since gloss etc. are given to the inner surface of shoes, even if the outer surface of shoes is damaged, a glossy surface etc. do not peel off.

  The coating 53 may be applied to the entire inside of the shoe, or may be applied to only a part.

  Further, the coating 53 may be given a color such as white or black, or may be mixed with gold, silver or pearl to give a glossy appearance. Alternatively, a gold foil may be applied on the inner side and a hermetic seal treatment may be applied thereon.

  In addition to the glossy coating 53, rubber 54 or fur 55 can be applied to the inner surface of the shoe. Alternatively, electrostatic flocking or the like may be used to plant the inner surface with microfiber or the like. This will be described below.

  The rubber 54 is a member having elasticity and flexibility, and for example, natural rubber, isoprene rubber, chloroprene rubber, styrene-butadiene rubber and the like are suitable.

  The rubber 54 may be provided on the inner side surface of the shoe by double molding, or a urethane material or a resin material containing fibers is applied to the inner side of the shoe and is provided on the inner side surface of the shoe through these. You can also. Since the shoe body is transparent, the urethane material, the fiber-containing resin material, and the rubber 54 are more aesthetically pleasing.

  By applying rubber 54 having elasticity and flexibility to the inside of the shoe, it is possible to absorb the pressure applied to the foot during walking. In addition, the forward sliding of the foot can be suppressed.

  The rubber 54 may be applied to the entire inside of the shoe or may be applied to only a part thereof.

  The fur 55 may be a faux fur made of a chemical fiber in addition to a real fur such as a rabbit fur or a fox fur. In any case, short hair is preferred because it is applied to the inside of the shoe. The fur 55 is suitable for use on a cold day because it has excellent breathability and moisture absorption, as well as excellent cold resistance and heat retention.

  The fur 55 may be affixed to the inside of the shoe via the rubber 54, or only the hair portion of the fur 55 may be directly implanted into the inside of the shoe. Since the shoe main body is transparent, the outer appearance of the shoe becomes gorgeous when applied so that the surface side of the fur 55 can be visually recognized from the outside of the shoe.

  The fur 55 may be applied to the entire inside of the shoe, or may be applied to only a part of the shoe.

  Further, in order to make the appearance look like a bare foot, the inner surface may be applied with a skin color (skin color, light orange color, wheat color, etc.). Alternatively, the insole may be a bare skin color. Further, finger decoration (pattern) may be applied to the inner surface of the finger portion, and decoration (pattern) of the nail may be applied to the inner surface of the nail portion. That way, even if you are wearing socks, you can look like bare feet.

  FIG. 19 shows a usage diagram of a shoe 1m and a sock 56 according to an embodiment of the present invention, and the sock 56 is worn inside the shoe 1m.

  By wearing the shoe 1m and the sock 56 of the present embodiment together, the size of the shoe can be easily adjusted, and the shoe can be fitted to the foot more. In particular, in socks (foot socks, foot covers) shaped so as to cover the part in contact with the shoe of the foot, the instep portion of the foot is wide open, it can be expected to be worn with no external discomfort.
