Description

The present invention relates to a pattern molding machine such as a unit sole or upper of footwear (sandals, shoes, slippers, etc.) that fits various human feet without using a wooden pattern, and footwear manufactured based thereon.

Shoe making has many processes, and there are a lot of tools, equipment, and materials, so it takes time to acquire technology and manufacture, and the finished shoes will not be comfortable to wear unless you actually wear them. It was the cause that made it difficult. There are people who are in trouble because the existing shoes don't fit their feet, so I thought that the shoe-making market would be activated if individuals provided a way to make shoes according to their size.

Provide a method that is simplified as much as possible in the three points of paper pattern production, shoe production, and comfort adjustment. If the work process is reduced and simplified, less tools, equipment and materials are used, and technical acquisition and production time can be reduced. In addition, insoles with a high degree of freedom are provided to improve comfort.

A paper pattern molding machine according to the present invention includes a temporary unit sole on which a foot is placed, a temporary upper that presses the instep of the foot, and a paper pattern formed therefrom, and the temporary unit sole and the temporary upper are provided. A plurality of rows of threading holes for temporary stitching are provided in the stitching areas when sewing, and the temporary upper is applied to the instep of the foot placed on the temporary unit sole, and the stitching area of the temporary upper is defined. Pattern molding in which the template of the temporary unit sole and the template of the temporary upper are respectively formed on the basis of the arrangement of the respective threading holes through which the thread is passed through when stitched to the stitching region of the temporary unit sole. It is a vessel.

In addition, the temporary upper is divided into an inner member and an outer member with the peak of the instep of the foot as a boundary, and an area corresponding to the peak of each of the divided members is used for temporary sewing for sewing these members. Based on the arrangement of the threading holes when a plurality of threading holes are provided and the inner member and the outer member applied to the former are stitched together along the ridge, the height of the upper is determined. In addition, the temporary upper pattern is formed. Further, the footwear according to the present invention is footwear manufactured by a footwear unit sole and footwear upper cut out from the above-mentioned pattern.

The footwear unit sole includes an insole and an outsole, and an edge of the insole that is sewn to the footwear upper is sewn with a thread exposed to the insole, The footwear upper is the footwear described above, which is stitched to the footwear unit sole by sewing the exposed thread with another thread.

An insole is laid on the footwear unit sole, and a hook-and-loop fastener is attached to a contact surface between the insole and the footwear unit sole so as to be detachable. The footwear described above, wherein a belt to be fastened is attached. The footwear is any of sandals, shoes, and slippers.

In the conventional method of making shoes according to the feet, after measuring the feet in an upright posture with a measure and correcting the wooden pattern, the pattern was made from the wooden pattern. The problem with this work is that the three-dimensional and curved legs are measured with a measuring tool that bends, so the numerical value varies depending on the sizing person, and the numerical value may change each time the measurement is taken. In addition, since the feet in the upright position are measured, there are cases where the shoes can be rubbed when walking with the shoes on. By using the paper pattern molding machine according to the present invention, it is possible to omit the measurement and wooden pattern correction process, which had previously required skilled experience, and to further confirm walking, thereby reducing shoe rubbing during walking. it can. This makes it possible to reduce the manufacturing time, shorten the time required for technical acquisition, and manufacture comfortable shoes. In addition, the manufacturing cost can be reduced because a wooden mold is not used. Furthermore, the conventional pattern making method uses a wooden pattern to make a pattern from there, but there are various methods, each of which has advantages and disadvantages. Instead of using a wooden pattern, you can make a pattern with simpler accuracy than the conventional method by using the pattern that is confirmed by walking with your upper legs and walking.

Further, since the cutting mold manufactured by the pattern molding machine is suitable for an individual's foot, the cutting mold of the shoe having a different shape can be manufactured according to the individual's foot by using the cutting mold. When manufacturing shoes according to the individual's feet, what is particularly required is the crust dimension of the part with the widest instep width and the crust dimension of the part with the highest instep height. The part with the widest instep is the ball girth, which is the part of the bone slightly behind the base of the big toe and little toe. The highest is the cuneiform bone, which is the instep bone just below the ankle. The size of the foot varies from individual to individual, but the average size can be adapted to many feet for toe and heel size. If the ball girth and the cuneiform dimensions of the wedge bone are known, a combination of the average size of the toes and heels can be used to produce general boots and boots that cover the entire foot. In addition, slippers and sandals that cover only the toes and not the heel can be manufactured in shapes other than those that are separated by peaks. In addition, if you create a dedicated pattern molding machine that matches the shape of the shoe, you can efficiently create a pattern that matches your foot.

The unit sole for footwear of the present invention has an insole and an outsole bonded together, and is sewn into the green part of the insole with the thread exposed. By using the stitching thread and stitching the exposed thread in the footwear upper hole and the footwear unit sole with a lace stitch, the shoe-making process can be reduced, less learning techniques and less manufacturing time. . Further, if the suture thread for the sewing is cut, the insole is separated from the outsole, so that the members can be easily replaced. In the case of manufacturing by the conventional method, it is possible to bond the outsole after stitching the hole of the footwear upper and the hole of the insole without bonding the insole without the exposed yarn and the outsole.

Further, the footwear unit sole has an advantage of reducing the cost because a molding die is not manufactured, compared to the case where a synthetic resin is poured into a conventional molding die to manufacture the unit sole. Furthermore, when a mold was manufactured, it was necessary to re-manufacture the mold when it was desired to change the shape of the bottom and the number of stitching holes. However, the present invention can be easily changed because the member is cut and manufactured. . Conventionally, there has been a method of stitching the leather and upper attached to the unit sole on the side of the shoe, but the sutures generated on the side of the upper may not match the customer's preference. According to the method of stitching using the exposed thread equipped on the insole of the present invention, it can be manufactured without impairing the appearance of the shoe.

The insole of the present invention can adjust the tightening of the instep using the upper belt when the instep changes due to swelling of the foot, the thickness of the socks, and the like, and the comfort becomes worse. The instep belt goes into the shoes, so the appearance is not impaired. As footwear other than sandals, it can be worn on shorts, boots and slippers. An advantage that each member can be adjusted by attaching and detaching with a hook-and-loop fastener is that an individual can easily adjust it in a short time when the shoe suddenly rubs on the go. In addition, the hook-and-loop fastener is elastic, so it absorbs shocks when walking, reducing the pain of the soles and octopus. If the insole becomes dirty, the hook-and-loop fastener can be removed and replaced. When putting the insole into a shoe, an attachment method other than a hook-and-loop fastener can be used.

An embodiment of the present invention will be described with reference to FIGS. In Example 1, the standard sandals in which the upper is separated into the inner side and the outer side are explained based on FIGS. 1 to 6 until the cutting dies E and G are manufactured using the paper pattern molding machine C. Then, FIG. Based on FIG. 8, a method for stitching the footwear upper H and the footwear unit sole J manufactured using the cutting dies E and G will be described. Example 2 is based on FIGS. 9 to 14 and uses a standard sandal cutting mold E to manufacture a single-sandal cutting mold M of FIG. 13 and a pump cutting mold P of FIG. explain. Thereafter, a pump pattern forming machine will be described with reference to FIG. 15 as an application example of the pattern forming machine. Example 3 is based on FIG. 16 and FIG. 17, and the insole T for providing a shoe manufactured based on a cutting die made to fit the foot and further adjusted to match the change in the instep is provided. explain.

Hereinafter, as an embodiment of the present invention, a paper pattern molding machine C for making sandal paper patterns will be described with reference to FIGS. The embodiment of the present invention is described in the case where the temporary upper A is divided into an inner member A4 which is the thumb side of the foot and an outer member A2 which is the little finger side of the foot with the instep peak as a boundary. To do. The pattern forming machine C shown in FIG. 2 is composed of the temporary upper A for holding the instep shown in FIG. 1 and the temporary unit sole B for placing the foot, and is formed by stitching them together. Is done. The configuration of the temporary upper A includes an inner member A4 and an outer member A2, and these are formed by stitching them at the ridge portion. The ridge portion threading hole A1 is arranged in a plurality of rows, and a hole to be sewn can be freely selected according to the size of the upper.

Next, the provisional unit sole B is composed of an insole B3 and an outsole B4. The insole B3 and the outsole B4 are bonded only at the hatched portion of the midsole bonding portion B2, and are located inside the hatched portion. Both sides of the bottom B3 are turned up. By turning up the insole B3, it is possible to use the side threading hole A3 and the insole threading hole B1 when sewing the temporary upper A and the temporary unit sole B. Further, since the side threading hole A3 and the midsole threading hole B1 of the temporary upper A are formed in a plurality of rows, the hole to be sewn can be freely selected according to the size of the foot. If the ridge stitching hole C1 and the side stitching hole C2 which are the stitched holes are copied on the pattern, a pattern suitable for an individual's foot can be manufactured without using a wooden pattern.

Next, how to use the pattern molding machine C will be described with reference to FIG. First, a provisional upper A and a provisional unit sole B are prepared by stitching a plurality of rows of holes according to a general foot size. Put your feet there, grasp the problem location such as the temporary upper A floating or tightening tight, if there is a problem, unwind and re-stitch. After that, if there is a problem with comfort after walking, this is repeated until the comfort is improved by unwinding the thread and sewing it again. In this manner, the hole positions of the suture holes C1 and C2 that match the individual foot size are obtained.

Next, a method of manufacturing the upper cutting die E using information on the suture holes C1 and C2 will be described based on FIGS. This method uses the information on the hole positions of C1 and C2 stitched in accordance with the individual's feet to produce a pattern, so that it is possible to produce a cutting die that matches the individual's feet. 3 and 4, the temporary upper mold paper D and the upper cutting mold E are made of thick paper or the like. FIG. 2 shows that the holes used for suturing are stitched holes C1 and C2, which are stitched to the feet. FIG. 3 shows the positions of the stitched holes C1 and C2 copied on the temporary upper template D. FIG. 4 shows an upper cutting die E produced by processing the temporary upper template paper D. 3 is manufactured based on FIG. 2, and FIG. 4 is manufactured based on FIG. Next, a method for copying the positions of the suture holes C1 and C2 in FIG. 2 on the temporary upper template D in FIG. 3 will be described. The hole positions of the stitching holes C1 and C2 in FIG. 2 are picked up one by one and copied as a black circle D1 of the temporary upper template D. As a result, the suture holes C1 and C2 that match the individual's feet can be obtained in the temporary upper template D. Next, a method of manufacturing the upper cutting die E of FIG. 4 from the temporary upper template D of FIG. 3 will be described. After the holes other than the black circle D1 of the temporary upper pattern D are omitted, a seam allowance is provided in parallel with the black circle D1 as in the upper seam allowance E1. By doing so, the upper cutting die E can be manufactured.

The manufacturing method of the temporary unit sole middle bottom paper F of FIG. 5 and the middle bottom cutting die G of FIG. 6 is the same as the manufacturing method of the temporary upper paper D and the upper cutting die E. By using the upper cutting die E and the middle bottom cutting die G thus manufactured, a sandal as shown in FIG. 8 can be manufactured. The insole cutting die G can be used as both the insole J3 and the outsole J4 in FIG.

Next, a processing method of the footwear upper H and the footwear unit sole J will be described using the upper cutting die E and the midsole cutting die G based on FIGS. 4, 6, and 7. Upper material for leather, synthetic leather, fabric, etc. used for footwear upper H is placed on upper cutting die E, which is cardboard, and cut along the outer shape. H inner and outer members can be manufactured. The insole J3 is processed by placing an insole cutting die G, which is cardboard, on a material such as leather or synthetic leather, cutting along the outer shape, and providing a threading hole by drilling. J3 can be manufactured. The processing method of the outsole J4 can be manufactured by placing an insole cutting die G on a material such as leather or synthetic resin and cutting along the outer shape.

Next, as an example of the sewing method of the footwear upper H and the footwear unit sole J based on FIG. 7 and FIG. 8, the exposed thread J1 sewn into the insole J3 is stitched by the stitching thread J2 by the stitch sewing. How to do it. The structure of the footwear upper H can be formed by stitching two members separated at the peak of the instep of the foot at the peak as in H1, and the footwear unit sole J and stitched on both sides There is a hole to do. The footwear unit sole J has a structure in which the thread is exposed at the edge of the insole J3 to be sewn with the footwear upper H in a state where the thread is exposed like J1, and the exposed thread J1 is in the insole J3. After being sewn in, the outsole J4 is bonded. Next, a method for stitching the footwear upper H and the footwear unit sole J is as follows. First, the ridge portion of the footwear upper H is stitched like H1, and then the holes on both sides of the footwear upper H and the footwear unit sole J The exposed thread J1 is stitched. At that time, the stitching thread J2 scoops up the exposed thread J1 and sews it for a sewing to complete a sandal as shown in FIG. Thus, by stitching the exposed yarn J1, the footwear upper and the footwear unit sole can be sewn without impairing the appearance.

An advantage of using a finished product of the bottom member, such as the footwear unit sole J sewn with exposed yarn, is that the shoe manufacturer can eliminate the process of processing the bottom member. The conventional method of processing the bottom material corresponding to the footwear unit sole J has been to prepare the insole J3 and the outsole J4 by attaching them together with a shoe-specific glue and shaving the outer periphery with a grinder. By omitting these processes, it is not necessary to acquire tools, equipment, materials, and techniques, which can be simplified. Further, compared with the case where a synthetic resin is poured into a conventional molding die to form a unit sole, there is an advantage that the cost is reduced because the molding die is not manufactured. Furthermore, when a mold was manufactured, it was necessary to re-manufacture the mold when it was desired to change the shape of the bottom and the number of stitching holes. However, the present invention can be easily changed because the member is cut and manufactured. . Conventionally, there has been a method of stitching the leather and upper attached to the unit sole on the side of the shoe, but the sutures generated on the side of the upper may not match the customer's preference. By using the exposed yarn J1 mounted on the insole J3 of the present invention, it can be manufactured without impairing the appearance of the shoe.

As an application example of the footwear unit sole J, it is possible to provide a shoe manufacturer with a unit sole having a structure in which both sides of the insole B are turned up like the temporary unit sole B. As an advantage, it is possible to save the trouble of the provider sewing the exposed yarn J1. However, the shoe manufacturer needs to glue the turn-up part with a ladle for the shoe after sewing the upper and the insole. In this case, it is not necessary to open a plurality of rows of suture holes on both sides of the midsole, and only one row is sufficient.

So far, the manufacturing method and the manufacturing method of the standard sandal cutting mold have been described. The following is the standard sandal cutting mold, based on FIG. 9 and FIG. A method for manufacturing M will be described. The shape of the single-layer sandal is shown in FIG. 13, which is a shape without stitching at the peak portion of the standard sandal. When manufacturing footwear, the size of the foot, which is called the ball girth C4 shown in FIG. Since this part has different insteps for each individual, adapting the distance of the ball girth C4 obtained with standard sandals to single-layer sandals can provide single-layer sandals tailored to individual feet. This method is for making sandals with different shapes based on the upper cutting type E tailored to the individual's feet, and provides a simple shape sandals by eliminating stitching at the peak of the standard sandals. Is to do. First, the upper cutting die E in FIG. 4 is overlaid as shown in FIG. At this time, the distance of the ball garth E2 is not changed. Further, the ridge stitch holes L2 are stacked in a well-balanced manner so that the black circles do not greatly deviate from each other. After that, when the overlapped ridge stitching hole L2 in FIG. 9 is omitted and the shape of the outer shape is smoothed and the shape is adjusted, a single-layer sandal cutting mold M can be manufactured as shown in FIG.

Further, a method for manufacturing the pump cutting die P will be described with reference to FIGS. 11 and 12, using a standard sandal cutting die, FIG. The shape of the pump to be manufactured is shown in FIG. This method is to produce a pump cutting die by combining the ball girth C4 of FIG. 2 and the average value of the toe and the heel with little individual difference in size. First, a pump cutting die having an average size as shown in FIG. 11 is prepared, and an upper cutting die E is placed on the die with a good balance so as not to change the distance of the ball girth E2. At this time, the upper part may overlap like N2, but it is assumed that there is no problem because the pump has a large open part and is not used. The unnecessary black circle in the central portion and the outline of the upper cutting die E are omitted and processed as shown in FIG. In this way, a pump cutting type P can be manufactured. If the instep of a wedge-shaped bone is also incorporated into this method, it is possible to produce a cutting type such as a general boot or boot, and a slipper shape that covers only the toes and does not cover the heel.

Next, a paper pattern molding machine having a pump shape will be described with reference to FIG. 11 and 12, the method of manufacturing the pump cutting type has been described. In these methods, the toe and the heel were manufactured in an average size. In the case where the toe and the heel are not the average size, or when making the pattern after confirming the comfort of the heel, a pump pattern forming machine S as shown in FIG. 15 can be used. The structure has cuts S1 on the toe, heel, inner side, and outer side, and a plurality of rows of threading holes S2 are open to the cuts S1. In FIG. 15, the end surfaces of the cut line S <b> 1 are abutted, but may be overlapped from the beginning. The usage is the same as that of the standard sandal pattern molding machine C, and a cutting mold is manufactured by copying holes stitched in accordance with the feet on the pattern. In the method of making a cut mold without a cut like the pumps in FIG. 14, the paper patterns are overlapped in the description based on FIG. 9 and FIG. 10, but the paper patterns are overlapped on the basis of the stitching holes by the same method. Can be produced. In this way, a pattern forming machine can be manufactured for each shape of the shoe by making a plurality of rows of threading holes in the place where the foot is to be adjusted by making a foot and providing the same pattern.

Next, a method for implementing the insole T of the present invention will be described with reference to FIGS. FIG. 16 shows an implementation method of the insole T, and FIG. 17 shows a state where the insole T is inserted into the pump. This insole T is for adjusting the tightening of the upper part by the upper belt T2 to improve the comfort. Further, when putting the insole T into the shoe, the upper belt T2 can be attached at a position where it cannot be seen from the appearance. The insole T can be used for the sandals of FIG. 8, but can also be used for the sandals of FIG. 13 and the pumps of FIG. Strap shoes such as sneakers can be easily walked by adjusting the tightness of the instep with the strap, but especially in pumps, the instep portion is not covered and there is no function to adjust the tightness on the instep portion. The problem that it is easy to take off and difficult to walk occurs more often than other shoes. In such a case, the insole T of the present invention is effective.

In the structure of the insole T, a hook-and-loop fastener T4 is bonded to the back surface of the insole member T1 as indicated by a hatched portion. Further, a hook-and-loop fastener T3 is fixed to the upper belt T2, and T3 and T4 can be attached and detached with each other. Thereby, the mounting position of the upper belt T2 can be changed, and the upper belt T2 can be adjusted according to the distance of the upper shell. First of all, the insole member T1 and the instep belt T2 are attached and detached so as to fit the instep position and instep circumference. At that time, the instep belt T2 is visible from the exterior as shown in FIG. Install in a position that is not. When the width of the upper belt T2 is wide and visible from the appearance, the width of the upper belt T2 is processed to be thin. When the position, instep, and width of the upper belt T2 are determined, the upper belt T2 is put into a shoe and joined by hook-and-loop fasteners T4 and U1 as shown in FIG. If there is a problem with walking, peel off the hook-and-loop fasteners T4 and U1, take out the insole T from the shoe, adjust the position, length and width of the upper belt T2 again, and then put the insole T into the shoe and walk. To confirm. This adjustment is repeated until the comfort is improved.

The insole T of the present invention can respond to changes in the instep. The distance of the instep will vary depending on the swelling of the feet, the thickness of the socks, stockings and bare feet. Depending on the compatibility of the foot and the shoe, the slight comfort of the instep may cause the comfort that was not a problem before, but it may become loose and the heels may float up, the instep may be tightened, and tight. Even in such a case, it is possible to adjust and adjust the tightening of the upper belt T2. In addition, when the heel floats up, it is possible to add an instep belt in the vicinity of the heel and adjust the upper part and the heel part with the upper belt.

Further, the use of the hook-and-loop fasteners T4 and U1 for joining the insole T has an effect of improving the elasticity. In the case of conventional insoles, some products may lose the elasticity of the sponge while being used, causing the soles of the feet to hurt and octopus. Such problems can be improved by using hook-and-loop fasteners. The structure of the hook-and-loop fastener is composed of a side raised in a hook shape and a side raised in a loop shape. The hook-and-loop fastener has a lot of space due to raising, so it has high elasticity and is suitable for use as an insole for shoes. It is more elastic than conventional sponge-type insoles. Further, when the insole becomes dirty, the hook-and-loop fastener can be removed and replaced.
