Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shoe with removable members and a method of manufacturing the shoe.

The production of today's women's and men's synthetic shoes and casual shoes is a capital-intensive process, requiring expensive machinery and skilled technicians to assemble the shoes from a wide variety of parts. It's a business. This leads to more expensive shoes and compresses the profits of traditional shoe makers and shoe sellers. In general, the cost of makeup has been replaced by sports shoes such as plus deck, rubber or cloth shoes such as oak shoes.
This will be a loss for the traditional shoe industry.

It is believed that shoe manufacturers, shoe sellers, and shoe consumers would benefit from having a basic shoe sitter that can have completely different appearances at a small expense.

Accordingly, various methods and means have been proposed to meet some of the above needs. One way in which the basic shape of the shoe can be varied considerably is by combining heels of different types, colors or lengths. If different heels for the basic shoe shapes were permanently used during manufacturing, not only would the shoe manufacturer have a considerable profit, but the realization of this manufacturing method would also make the shoes cheaper for sellers and shoe consumers. Now, sellers and shoe consumers can afford to buy high-quality shoes. Most of the prior inventions in this field have been based on the idea that the heel and the shoe that requires the heel (and other sheath parts) are manufactured separately, and that once they are assembled in a factory, they remain there for the life of the shoe. It concerns a shoe system that maintains the wearer's feet and cannot be put on or taken off again; in these cases,
The shoes are not designed to easily install different heights or new heels for fashion or reproduction purposes. Therefore, shoe sellers and shoe consumers are denied most or all of the benefit of changing the basic shoe design by simply selecting a heel to be attached to a basic shoe that requires a heel.

Alternatively, you can replace the currently installed heel with a different heel, new heel, tall heel, short heel, long heel, sporty heel, narrow heel, thick heel, or colored heel. heels,
The benefit of replacing heels covered with expensive covering materials and matching with clothing is also lost.

In view of the above, the basic design of the heel shoe of the present invention includes a downwardly sloping outer circumferential side wall that protrudes vertically downward and extends along both lateral sides and the rear side, and a downwardly inclined outer circumferential side wall in the center thereof. A heel is formed with the necessary sole member, made of a semi-hard molded material with a flat lower end wall having a cylindrical socket with an opening. A small diameter hole passing through the sole member is preferably formed on the upper surface of the sole member that overlaps with the thick portion of the base.

On the other hand, it is preferable that a cylindrical boss located at the center and projecting upward is formed at the upper end of the heel portion, and that a screw hole opening upward is formed in the center of the cylindrical boss. Further, the cylindrical boss is surrounded by a flat upper end surface. An upright body (flange) extends along both lateral and rearward sides of the upper end surface of the heel member. The inner surface of this flange is sloped to accommodate the heel jack. The heel member is removably attached to the required sole member by properly inserting the cylindrical boss into the cylindrical socket, passing through the opening on the sole side, and screwing a screw into the screw hole in the boss.

The system also consists of four basic components: a decompositionally formed insole/II! j jack unit,
By using a removable track material with an internal attachment member, an upper sheath material, and an outer sole sheath material, even a small business or a small group of craftsmen can manufacture cosmetic shoes.

Preferably, the midsole/heel jack unit comprises upper and lower layers of sheet material and a body portion of plastic integrally molded between these layers. Also, during shoe manufacturing, the midsole/heel jack unit is inserted into the upper sheath and fixed in place such that the heel jack is exposed from the bottom.

An outer sole sheath is attached to the lower surface of the front part of the upper sheath, and a heel of various heights and types can be removably fixed in place.

The present invention will be described in detail below with reference to the drawings.

Figures 1 to 3 show the upper sheath 2 schematically shown as a foot shape.
12, an undersole 214, a sole member 216 (which in a preferred embodiment includes a ground contacting insert 218), and a heel member 220 (which includes a lift element 222 in a preferred embodiment). Shoe 210 is shown with a removable connector 224 (which in the preferred embodiment is a screw).

This sole member 216 is inserted into the inserting plate 218 during molding.
It is preferably injection molded of a somewhat hard plastic material such as nylon or ABS resin. In addition, the insert plate 218 is made from real tanned leather,
The sidewalls 226 of the sole member 216 are cut into a radially outwardly recessed profile so that the interposer plate 218 can be securely secured to the opening 228 of the sole member 216 during molding of the sole member 216. If this insert plate 218 is made of genuine leather, the fixing effect is facilitated by the fact that the loose fibers of the side wall 226 are embedded in the plastic material of the sole member 216, particularly of the surrounding opening 228.

If necessary or desired, metal studs (not shown) may be embedded in the instep or heel connection portion of the molded sole member 216 during injection molding.

In manufacturing the shoe 210, the sole member 2
16 and the upper sheath 212 is attached to the undersole 214 or the sole member 216, or to both the undersole 214 and the sole member 216.

The lower side of the sole member 216 extends from the area where the insert plate 218 is stored to the area where the heel is attached.
In the region where the heel is attached, the sole member 216 suddenly (discontinuously) thickens until it reaches the protruding boss 23, which usually constitutes a pedestal or jack for the heel.
4 is formed vertically downward.

As can be seen in the plan view, the boss 2313-4 of the first embodiment is shaped as if the C-shaped portion of the sole member 216 had forgotten to form two opposing, generally vertical, back-facing shoulders 236. As you can see, it suddenly becomes wider and longer.

The boss 234 has a flat full inner wall 238 and a significantly rounded rear outer wall 240, with the horizontal cross-sectional shape of the boss 234 being generally rounded D-shaped. Further, the outer wall 240 is curved to 3/4 of the outer circumference of the boss 234, and furthermore, the circumference of the upper end 242 of the boss 234 is slightly larger than the circumference of the lower end 244 of the boss 234, and is inclined downward.

The lower surface 246 of boss 234 is typically horizontal and flat. Also formed within this boss 234 is a downwardly opening cylindrical socket 248 having an interior side wall 250 and a top end wall 252 (if the sole member 216 had an embedded metal shank, the end wall 262 may optionally be formed on the underside of the shank).

The sole member 216 is formed concentrically where it overlaps the cylindrical socket 248 where the material is fairly thin 14-. The diameter of this opening 254 is a considerable fraction of the inner diameter of the cylindrical socket 248. Further, a recess may be appropriately formed on the upper surface 230 of the sole member 216 in contact with the opening 254 so that, for example, the head of a flat screw does not protrude.

The heel member 220 also includes an external attachment member of a women's high heel, such as a conventional spike-shaped lift element 222 that projects upwardly from the lower end.

This heel member 220 has a rounded D-shaped cross section throughout its height, ie, up to level 258. From this level 258 to the top, the heel member 220 exists as a flange or shell 260 on the outer wall. The core and inner wall of the heel member 220 are cut out to form a recess 262 that is open upwardly and forwardly.

Within the recess 262, the inner sidewall of the shell 260 is located at the upper end 2.
64 slopes downwardly to a flat, horizontal floor 268 having a lip 258 as a front end.

Disposed in the center of the flat floor is a vertically upwardly projecting cylindrical boss 270 having a cylindrical outer wall 272 and a flat, horizontal upper end surface 274 .

This cylindrical boss 270 has a vertical screw hole 276 opened upwardly formed in its center.

The heel portion U 220 is preferably made from a semi-hard material for injection molding, such as nylon or ABS plastic, into which reinforcing material (not shown) may be incorporated.

All or a specific outer peripheral side wall of the heel member 220 may be covered with a decorative material such as colored leather, decorative urethane, or vinyl.

Such a heel part + J 220 and sole member 21
6 are spatially oriented as shown in FIG. 1, but the members are assembled to each other in close vertical alignment. Therefore, the boss 220 in the heel member 220
The upper surface 274 of 20 lies near the upper surface 2520 of the heel member 220 and the lower end surface 246 rests on the floor 268;
Furthermore, the inner surface 278 of the upright and inclined shell 260 is attached to the pedestal 234.
Sole member 2 until it forcibly engages with the rear/lateral outer end surface.
16 into the socket 248 on the lower side of the pedestal.

This insertion relationship is maintained by threading the screw 244 through the hole 254 and into the threaded hole 276, with the screw head tightly engaging the recess 256 in the upper surface of the sole member 216.

The underlay 214 covers the screw heads within the recesses 256, thereby hiding the screws from view and preventing the screw heads from being felt by the wearer's heel. This underlay is made with adhesive or the like so that this area can be easily turned over.

In the first embodiment, the upper edge 264 of the shell 260 is flush with the outer edge of the upper surface 230 of the sole member 216, and the outer edge of the undersole 214 is placed between the edges so that the assembled shoe 210 has a fine finished appearance. covers equally.

To replace the shoe 210 with a black sole and green heel to the shoe 210 with a black sole and red heel,
It is necessary for the shoe manufacturer, seller, or consumer to remove the green heel and install the red heel. In a preferred embodiment, attachment/detachment involves flipping up the rear of the underlay 214 until the heads of the screws 244 are exposed, loosening the screws 244, pulling the heel member 220 vertically downward, and then inserting the desired heel member 220. Finally, the rear part of the underlay 214 is glued to the surface 230 to complete the process.

A shoe according to a second embodiment of the invention is shown in FIGS. 3-5. In these figures, corresponding elements are numbered the same as those not shown in FIGS. 1 and 2, and are denoted by ''.

All that the shoe shown in FIGS. 3-5 differs from the shoe shown in FIGS. 1 and 2 is that the outer end M, shown at the upper end of the shell of the heel member 220 in FIG. Heel member 22
0', and instead forms an integral part with the sole member 216' at a corresponding position M'. Therefore, in the shoe of the second embodiment, the upper end 264' of the shell 260' in the assembled shoe 210' is located at the base 237 of the outer surface 280' of the outer end M' of the sole member 216! It engages around the rear and left and right sides of l'.

In both these shoes, the left and right front ends 266.266' of the shell 260.260' are connected to the sole member 216.216'h.
260, 260'.

Although the present invention has been shown as a high heel women's shoe, all examples of boots and other similar footwear or shoes may be used for men's, women's, or children's shoes. It can be formed regardless of the presence of the heel. For example, the Heene member may be 20 to 100 mm high, and the screw 244 may have a length of 2.5 CII+ with a head of 51 mm.
It may have a diameter of n. Screws 224, or even other equivalent fastening means (including adhesives), may be used instead to removably hold and cover the heel member in place. Materials used for the underlayment 214, 214' also include those sold under the TEXON and BONTEX brand names. The thickness of these is usually 2III
It is LIL.

A central vertical groove in the front wall of the heel member 282, 282' may be formed to accommodate the outer edge of a decorative sheet member or leather covering the side wall of the heel member.

The typical thickness of the sole in the area of the sole plate 218 is 3.
It is mm.

The insole system of the present invention will be described with reference to FIGS. 6-16.

In FIG. 6, four main parts of the shoe 10 are shown: the midsole/heel jack unit 12, the upper sheath 14, and the heel 1.
6 and an external sole 18 are shown. This midsole/l Jack Knit 12 is a new development of the present invention.

This two-part separator 171 is of a conventional type, for example made of lined or partially lined leather, or of leather only.

The manner in which the heel 16 and insole/heel jack unit 12 relate to the heel jack 20 will be described more precisely in connection with FIGS. 1-5.

First, the upper sheath material 14 of the present invention is manufactured by a conventional method. The upper sheath 14 thus has an upper opening 22 through which the user's foot can enter and exit when the shoe is in use. Further, the midsole 7M jack unit 12 is also inserted into this upper opening 22 when the shoe is assembled. The upper sheath member 14 further includes a rear projection 26 located at the center of the heel, a front projection 28 located at the center of the toe and foot section, and an intermediate portion between the rear projection 26 and the front projection 28. A longitudinal central gap 30 is provided therebetween and centrally formed at the bottom of the upper sheath member 14.

The rear protrusion 2G has an insole/heel jack unit 12 that is connected to the upper shoe 1. The heel jack 20 is sufficiently large that the heel jack 20 projects downwardly from the bottom of the upper sheath 14 when inserted into the upper sheath 14 .

This upper sheath material 11 again! When assembling the insole/heel jack unit 12 to 'l, the insole/heel jack unit 1
2 and at least one of the internal surfaces 34 of the bottom of the upper sheath 14 are coated with a suitable adhesive. This adhesive is applied only to the inner surface area, ie the surface outside the chamfer where the rear projection 26 and the front projection 28 are located. This inner surface area includes a periphery 36 of the rear protrusion 26 and a periphery 38 of the front protrusion 28 .

Further, the upper sheath material 14 is pressed into the midsole/heel jack unit 1 by platen means (not shown) using a conventional press machine.
It is folded to the bottom surface of 2. As a result, an uneven pattern 40 is formed as shown in FIG. 14. This uneven pattern 4o
has a central portion 42 that includes a longitudinal central gap 30.

This longitudinal center gap 30 has substantially parallel boundaries 44 around the sides and is formed wide enough to accommodate the curved portion 46 in the outer sole 18 if the outer sole 18 has a curved portion 46. Ru. Alternatively, the external sole 18 may include the curved portion 46
It doesn't have to be. In this case, the corresponding central portion 42, in other words the protrusion, is omitted.

Alternatively, the outer sole 18 may simply not be attached to the lower surface of the intermediate assembly 48 when it is assembled. This textured pattern 40 includes the front quarter of the edge 36 at the rear and is located at the tip 54 of the heel 16, regardless of the presence or absence of the curved tab 62 in which the outer sole 18 is housed in the central portion 42. It includes a curved portion 50 having a boundary line 54 forming a jig (stitch).

Finally, the uneven pattern 40 is located at the front of the edge 58 at 1//l.
The curved portion 56 has a border 60 that forms a jig that includes and is uniformly positioned on the outer sole 18 .

In all cases, when the shoe 10 is to be further assembled, at least one member interconnecting between the upper part 6/1 and the lower part 66 is coated with a suitable adhesive conventionally used in shoe manufacturing, and the two parts are bonded together. Attach the outer sole 18 to the midsole/heel jack unit 12/intermediate assembly 118 by pressing the A screw 68 is passed through the opening lower 0 formed vertically in the center of the shoe and screwed downward to fix the inner mustard 16 of the shoe 10.
The assembly is completed. This screw 68 is screwed into an upwardly opened screw hole 72 formed in the center of the upper surface of the heel 16.

The method of assembly of heel 16 and heel jack 20 will be described in conjunction with the corresponding structures shown in FIGS. 1-5. That is, in this construction the heel jack 20 is formed on the outer sole member rather than the inner sole member. In general, the midsole/heel jack unit 12 is mostly a fairly thin member, and a thick heel jack 20 extends downward from the bottom in the remaining heel part (pedestal part) near the rear part. There is. This heel jack 20 has a front side,
Both sides and the rear side each have an inclined circumferential wall 74, and these are non-circular, ? In other words, it forms an abbreviated horizontal cross section. A socket 76 having a cylindrical wall opening downward is formed in the center of this pedestal portion. Further, the main body of the midsole/heel jack unit 12 is formed with a small diameter open lower 0 perpendicular to the central axis of the roof of the socket 76 and having a conical recess 78 at the top. On the other hand, at the upper end of the heel 16, a cylindrical boss 80 having a screw hole 72 formed therein is concentrically formed and protrudes upward at the center. The base of this cylindrical boss 80 has a flat end face 82 surrounded by an upright annular 7 flange 84.
surrounded by. The inner surface of the annular flange 84 is sloped to fit over the outer sidewall of the heel jack 20.

Further, the upper surface 88 of the annular flange 84 is recessed in a substantially spherical shape. However, the front portion 90 of this upper surface 88 is recessed in a substantially cylindrical shape.

The heel 16 inserts the cylindrical boss 80 into the socket 76,
This socket 76 is fitted into a heel annular socket 92 formed between the cylindrical boss 80 and the side wall 86 of the flange 84, and is freely assembled to the lower side of the intermediate assembly 48. Thereafter, the screw 68 is screwed downward until the head matches or sinks below the edge 78 of the open lower 0, and the screw 68
The threaded portion of the heel 16 engages with the socket 72 of the heel 16.

Heel 16 can be easily replaced with a heel 16 having interconnecting surfaces similar to intermediate assembly 48. The replacement heel 16 is available in various lengths and the sidewalls 94 are covered in various colors, fabrics, or decorations. For example, this heel 16
The length may be between 20 and 80 cm, and may be thick, medium or thin, or may be in men's or women's styles.Also, to match or contrast with the material used for the screen of the upper sheath 14. Alternatively, the plastic sheet, leather or fabric may be decoratively covered to resemble a layer of laminated leather.

The main body of the heel 16 is preferably injection molded using nylon or plastic 4A size, which are conventionally used in the manufacture of heels. In such a case, the threaded socket 72 may be a tubular brass section that is inserted into a mold and embedded in the plastic material of the body of the heel 16.

On the other hand, the midsole/heel jack unit 12 is preferably manufactured in advance by the following method.

Paper-like fibrous products sold under the trademarks EXON and BONTEX have recently become commercially available, and this sheet material can be heated under moderate pressure (e.g. 10 atmospheres) and humidity (e.g. 150 degrees Celsius). It is molded and punched out. This maintains the molded shape like a taco shell.

To manufacture the midsole/heel shirt cuckoo knit 12, first, two layers 98 and 100 suitably cut from a moldable and hardenable sheet material are placed in an injection mold (not shown) of a specific shape. . In this case, layer 98 is placed against the upper mold and layer 100 against the lower mold.

The molds are also shaped to grip layers 98 and 100 together at ring 102. Layers 98 and 100 meet at ring 102, but with a larger diameter opening 104 in which heel jack 20 is formed downwardly from where a smaller opening for screw 68 is formed through top layer 98.
are each radially and laterally spaced from where they are formed through the bottom layer 100.

The upper and lower surfaces of each mold have corrugated shapes corresponding to each other, so when the mold is closed and injection is started, an imitation of the overall shape of the midsole is formed with an edge 106 as shown in the figure. . This edge 106 is formed all over the periphery, but is particularly noticeable from the bulge at the base of the thumb to the heel. Also, the highest part of this edge corresponds to the arch of the foot, which corresponds to the inside 108
It is.

Preferably, layer 98 is configured so that it does not extend significantly forward of ring 102. This entire end 110 is shown in FIG. However, some types of shoes have layers 98 and 1.
00 also does not need to protrude to the front of the ring 102.

This modified example is shown in the middle sole/heel jack unit 12 in FIG.
'It is shown.

While blanks 98 and 100 are held in the mold, a solid plastic synthetic resin is injected through the openings in layer 98 or layer 100 and into the mold. This plastic member is
forming a thin lenticular 112 near the top of the large aperture 104 in the entire area enclosed by the ring 102 between layers 98 and 100, i.e. near the tip of layer 98;
It flows through the opening in layer 100 into a corresponding portion of the lower mold to form heel jack 20 . If the heel jack 20 is to be reinforced, a piece of brass, aluminum or other metal can be placed in a mold and embedded in the plastic. Once the plastic has thus been injected into the pocket 114 forming the lenticular 112 and the heel jack 20, and the layers 98 and 100 have been molded decompositionally, the plastic member is allowed to cool naturally, after which the layers 98 and 100 are molded. 100 is integrally coupled with the body 116 of the lenticular 112/I jack 20 and removed from the mold as a midsole/heel jack unit 12 having the shape shown.

Further, the lower mold not only forms a regular mold (pedestal) downward from the layer 100, but also forms a pattern 118 of dust corresponding to the uneven pattern 40 described above. In fact, the textured pattern 40 may be forced onto the underside of the upper sheath 14 to match the pattern 118 when the upper sheath 14 is assembled into the midsole/heel jack unit 12.

The plastic for the main body 116 is preferably one that is conventionally used in the manufacture of hard elastic inner soles and outer soles of decorative shoes, such as nylon, ABS resin, or solid polyurethane.

Alternatively, the body 116 may be preswaged and injection molded to have approximately the shape shown, and then a layer 98 of a simpler plastic may be applied with or without additional adhesive.
and 100 may be combined.

29- The outer sole of the shoe 10 is preferably one conventionally used as an outer sole member such as PVC, TR or leather. When the outer sole 18 has a rearwardly projecting curved portion 46 that mates with the central portion 42 of the recess on the underside of the intermediate assembly 48 , the outer sole 18 preferably extends so far that the rear end 120 is covered by the heel 16 . It has a length of If necessary or desired, 122 is formed at the upper tip of the heel.

The edge 104 surrounding the end of the midsole/heel jack unit 12 is, for example, 20 mm high at 106 and approximately 6-8 mm at the corresponding location on the outside. In the raised area of the base of the thumb and in the finger area, the height of the edge 104 (if any) may be significantly reduced, for example to about 2 m111.

Similarly, the recessed pattern 118 on the underside of the midsole/heel jack unit 12 preferably has a depth of about 2111111.

The shoe of the invention thus allows for easy assembly of the four main components. A decoration, such as a backing (not shown), may also be used to cover the foot supporting heel portion of the midsole and the upper tongue of the curved portion, and to hide the heads of the screws 68. Finished shoe 10 with a foot-conforming and foot-supporting surface provides curved support and horizontal support to cure minor foot problems such as flat feet and make walking safer and more secure. I'm helping out.

The shape of the upper part of the heel is an insole/It! jack unit 12
/ corresponds to the shape of the intermediate assembly 48 consisting of the upper shoe 14,
These surfaces substantially cover all interior surfaces that abut, are of strong and attractive construction, and can be replaced at any time during the life of the shoe 10 with a decorative, replacement, or decorative heel.
