Abstract

Shoe has an inner assembly (48) having a deformable portion (46, 50) which acts together with the shoe upper (24) to adjust the girth of the shoe to fit feet of differing widths and girths. Pref. the portion is resiliently deformable and can be made of elastic sheet material, on adjustably tensioned spring or a deformable gas filled bladder. The elastic material can be a spandex fabric. The inner assembly (48) can be made in part of plastic foam.

Description

BACKGROUND OF THE INVENTION In order for a shoe to fit properly on a foot, the length, inner width, and girth size of the shoe must match the movement of the foot. In the text, the girth size refers to the size of the circumference of the foot measured in the left-right direction. In other words, it is the size measured along the bulge, neck, and instep of the big toe. Therefore, in the case of shoes, it refers to the size of the inner width and circumference of the shoe that hits the girth portion of the foot. In the conventional shoe making method, the shoe width is divided into 9 kinds or more, and the shoe width has been devised so as to fit the foot by using the shoe width according to the size of the shoe. However, the girth size is usually different on the left and right. Also, due to the accumulation of water in the legs during the day, the width of the legs is 1 to 1.
Expand by 5 or 2 sizes. For these reasons, it is not possible to adjust the girth size sufficiently by the shoemaking method that is generally used. However, the current mass production method provides only one girth size for one shoe size in order to suppress the production cost. For this reason, shoes that fit perfectly on the foot are rare, and rather, most shoes do not fit the foot. On the contrary, over the long term, many shoes bring various obstacles to the foot.

For these reasons, the development of shoes that can adjust the shoe width and girth size economically and practically has been awaited. The shoe according to the present invention has a girth-size adjusting structure that is hard to see from the outside, and is used for a shoe using a conventional sole and an instep portion (all portions above the sole) and various other types of shoes. Can be applied, so it is economical and practical.

Several shoes with adjustable girth size have been developed so far. For example, shoelaces, belts, or
These are shoes that adjust girth size from the outside. However, the girth size is ideally adjusted according to the bulging part of the base of the big toe, and it is not possible to make sufficient adjustment with a shoelace or a belt. Moreover, style-conscious loafers, high heels and other fashionable women's shoes, or boots do not have these girth adjusters. Also,
For infants, the elderly, and people with physical disabilities, it is difficult to manually adjust the girth size by using shoelaces or belts, and therefore girth shoes that are automatically adjusted are particularly desired.

The inventor has invented various girth adjusting shoes and has obtained U.S. patent numbers such as 3,404,468, 3,541,708 and 3,686,777. However, none of these were commercially viable in various respects and were not worth commercializing.
For example, Nos. 3,541,708 and 3,686,777 have drawbacks such that the structure is too complicated and it takes too much time and cost for mass production, and it is easily broken when dust enters. No. 3,404,468 had similar drawbacks, and it was inferior in durability and style to ordinary shoes. 3,
The 404, 468 No. 11, 12, and 13 types did not have sufficient girth adjustment and were not worth putting to practical use. However, despite various drawbacks, through these inventions, finally,
We were able to create the mechanism of R & D and bring about this invention.

U.S. Pat. Nos. 3,442,031 and 3,922,800 provide girth adjustment by raising a portion of the insole surface. Therefore, when the girth size changes, the toes become higher together. To use this method to fit the front and back of the shoe to the foot, girth adjustments must be made on the front of the shoe. However, if the adjustment is made only with the frontal area, the balance is lost and the "tread" of the shoe (the area where the shoe touches the ground) is affected. This is because the relationship between the height of the heel and the bulge of the base of the toe collapses. Normally, the girth size is different on the left and right, so
When the girth adjustment is performed in this way, the distance between the ground and the toes will be further different between the left and right. For this reason,
In the long run, the legs may be deformed.

The inventions of U.S. Pat. Nos. 490,998, 2,691,227, 3,436,842 are structurally similar to this invention, but functionally quite different. For example, these inventions perform girth adjustment in a weightless condition. However, according to the present invention, the adjustment can be performed both in a weighted state and a weightless state. This property is especially important because the discomfort that occurs when the shoe does not fit on the foot occurs when the person is under weight. Also, 2,691,227 and 3,4
Nos. 36,842 are not structured to prevent the intrusion of dust or stones.

U.S. Pat. No. 3,693,270 secures a flexible sponge in the boot without the need for a zipper or similar device to move the foot in and out. However, since this sponge causes heat and pressure when it is applied to the groin of the big toe, it cannot be used for general shoes and formal shoes that require girth adjustment at the bulge of the big toe.

U.S. Pat. No. 4,736,531 provides girth adjustment by wrapping the front of the foot with a partially elastic slipper-type insole. The back of the slipper-type insole is fixed to the sole, while the top of the slipper is separated from the instep. This method can keep the tongue of the shoe straight. But,
If there is a person with a slender foot, there is a gap in the tip of the foot, and as a result, the sensitive part of the groin of the big toe, that is, the joint part used when walking, may be distorted when walking with a large thigh U.S. Pat. No. 4,038,762 inserts hard-bottomed shoes, such as alpine ski boots, into a bag of sticky and fluid objects. Since general shoes perform girth adjustment along the bulge of the big toe, that is, the part where the MP joint (metatarsus / phalange) bends when walking, this method cannot be applied to general shoes. Other than this, there is a method of using air, gel (gelled body), gas, plastic foam, or the like. However, in either case, it is good to use it with shoes with a firm sole so that it is applied to the back of the groin of the big toe, but it is too stimulating to use it directly against the bulge and it feels uncomfortable. , Not good for your foot health.

SUMMARY OF THE INVENTION The purpose of this invention is to create a girth adjustment structure that is invisible to the outside and also be applicable to shoes using conventional soles and to any other type of shoe. That is.

The shoe according to the invention is made up of freely deformable uppers.
The instep side is firmly fixed to the sole or the sole. The girth adjusting structure is arranged in the cavity between the instep and the sole. This girth adjustment structure has an inner lining structure in which the lining is stretched over the inside of the shoe. The inner lining structure is attached to the back side of the uppermost part of the instep, and since it has elasticity, it deforms according to the girth of the foot. Also, since the instep side is also elastic, it deforms according to the movement of the upper part and adjusts the girth. Deformation of the upper part occurs only while wearing shoes and walking, so it is almost invisible.

As another application of the present invention, there is a method of stretching a backing made of a material having low elasticity on the side of the foot. The lining is attached to a stretchable panel under the foot with a removable midsole between the panel and the foot.

Another application is the reverse use of the functions described above. Stretch the elastic backing on the side of the foot, on the contrary,
Use a material with low elasticity for the bottom panel.

Although not shown in the figure, in another application, the side lining and the panel portion under the foot are made of one stretchable material. This structure is especially suitable for "tube"("tu
Suitable for pipe-structured shoes called bular "type".

In another application, the instep backing, which is made of less stretchable material, is attached to the underfoot panel and insole, which is also made of less stretchable material. The panel and insole are mounted on a frame structure whose size can be adjusted in the left-right direction. The frame structures are preferably connected to each other by a bridge portion which acts like a hinge. The bridge is then fitted with springs or other resilient material, cables, cams or other such adjustment devices. in this way,
When the foot moves left and right, the frame structure sways toward the side of the backing, adjusting the girth size of the inner backing structure. Since the deformation of the instep occurs only when the weight of the shoe is applied, a part of the insole must be attached to the body of the shoe even when the weight is not applied. In the unladen state, the upper retains its original shape regardless of the girth size of the person wearing the shoe.

Another application is a girth size adjustment structure designed for low cost shoes. In this structure, the girth adjusting structure is not visible from the outside as in the above-mentioned example. The lining is made of a stretchable material, part of which is attached to the upper of the shoe. Therefore, when adjusting the girth size according to the shape and size of the foot, the contour of the instep and the backing is slightly displaced. In this construction, the entire instep and backing edges should be firmly secured to the bottom panel.

In order for the structure and purpose of the present invention to be properly understood, a more detailed description will be given below with reference to the drawings.

Detailed Description of the Invention Next, taking a loafer shoe as an example, a detailed description of the adjustable girth shoe will be added with reference to the drawings. The loafer shoes are taken as an example because they are easy to explain.
It can be applied to boots, sneakers, slippers and all other types of shoes. Reference numbers in the following description are numbers assigned to each function. Therefore, if the numbers are the same, it means that they have the same function.

1 to 3 are basic examples of the present invention. In the shoe 20, as a feature of the present invention, it is desirable that the instep portion 22 (the entire portion above the bottom skin) be made of a stretchable material such as leather. The upper 22 is composed of a toe skin 24 and a plug skin 26. The toe skin 24 and the plug skin 26 are sewn together by a seam 28, and the seam 28 extends along the edge of the plug skin 26 to the front portion of the shoe. The back of the shoe has an inverted pocket, or a toe cap 30, overlying the toe cap 24. The tab skin 30, the upper 22 and the upper end of the lining 46 are covered with a collar or folded skin 32 and sewn together. The sole portion 34 is a commonly used type, with heels 42, insteps 43 and constrictions.
Includes parts such as 49, groin of the base of the big toe 45, and toe 47. The construction is made up of a unit shoe sole 36 and a rubber intermediate sole 38. The material of the unit shoe sole 36 is made of commonly used rubber, and may be cut from what is called a "blocker". The bottom of the rubber middle bottom 38 is
It is joined to the upper portion of the unit sole 36 by a bonding agent or other method. The periphery of the rubber intermediate bottom 38 is preferably attached to the bottom portion of the toe skin 24 by suturing if possible.
A feature of the shoe 20 is an adjustable shoe interior 48, which comprises a backing 46 and an insole 50. support
Use a non-stretchable material for 46. For example, Cambrelle, a nylon material (non-woven fiber) provided by Faytex of Braintree, or other non-stretchable fibers may be used. The backing 46 has its upper end connected to the upper end of the toe skin 24, while the other parts are separated. However, at the heel area, the stitches 3
It is sewn by hand with 0 and the toe skin 24. The insole 50 is made of stretchable fibers and is firmly sewn to the backing 46 at the bottom. The interior 48 of the shoe is composed of an insole 50 and a backing 46, which covers the sides and bottom of the shoe. For the insole 50, it is preferable to use a stretchable unit fiber called spandex, but other stretchable fibers may be used. Also, preferably, there is a removable insole 44 to cover the seam of the backing 46 and insole 50. The insole 44 can prevent the insole 50 from being worn, the backing 46 and the stitched portion of the insole 50 being frayed, or the foot hitting the stitched portion. The length of the insole 44 should be larger than the length of the inside size of the shoe, and the width should be the maximum size within the allowable range of the shoe type (the shoe type when the shoe was made). Also, it should be able to be removed from the inside 48 of the shoe so that it can be taken out immediately when foreign matter enters and for easy cleaning.

FIG. 2 is a cross-sectional view showing a state where the weight of the insole 50 of the shoe 20 is not applied. Therefore, the insole 44 is floating in the air.
In this state, the insole 50 has the smallest width and the backing 46
The distance between the bottom edge of the and the insole 50 is also the shortest.
The contour of the upper part 22 also retains the shape of the shoe mold when the shoe is made. On the other hand, when wearing shoes, as shown in Fig. 3, the insole 50 stretches and the lining 46 deforms, so that the shoes fit perfectly to particularly important parts such as the groin of the big toe, neck, and instep. Has become. Then, the inside of the shoe 48 extends according to the girth size of the person wearing the shoe so that the shoe fits over the entire foot. Also, as shown in FIG. 3, in the state where the shoe is worn, the instep portion 22 is slightly enlarged in the left-right direction, and the shoe interior 48 and the insole 44 are pushed downward by the pressure of the foot. Then, within the allowable range of the girth size of the shoe, the upper part 22 is deformed so as to fit the girth size of the wearer.

4 to 7 are examples in which the concepts of FIGS. 1 to 3 are used in reverse. That is, use a stretchable material on the side or top of the shoe and a non-stretchable material for the area under the foot. FIG. 4 illustrates the structure of a moccasin shoe as an example. Upper part 22
Is shaped based on a fixed insole 58. Fixed insole 58
Is made of Texon or similar material. The shoe interior 56 consists of a backing 51 and an insole 44, the two parts of which are sewn together. Backing 51
Is made of spandex or a stretchable material similar to it. The insole 54 supports the insole 44 and is made of a non-stretchable material such as Cambrelle. 4 to 6 are application examples of moccasin shoes. The seam 28 is a pseudo seam (virtual stitch) formed by heat, and in fact, the plug skin 26 and the toe skin 24 are made of one sheet. The machine that creates the seams or creases by thermoforming is provided by Geo.Knight, Blockton, Massachusetts. As shown in FIGS. 4 and 5, the seam 28 and the backing 51 are sewn while the shoe is not under pressure, ie, the shoe is not expanded. FIG. 6 assumes that a person with a relatively wide foot wears shoes, and the seam 28 and the backing 51 are expanded. Also, the instep 22
Is deformed along the sides as in FIG. 3 and along the expanded seam 28. FIG. 5 shows a state in which the shoe is not worn, and the pressure on the inside 56 of the shoe is zero or very small. The virtual suture and the inside of the shoe 56 may be combined together, but the girth adjustment can be made by performing only virtual suture. Alternatively, as shown in FIG. 7, without performing virtual stitching, girth adjustment can be performed only within the shoe interior 56. In this case, the girth adjustment is performed by the expansion and contraction of the toe skin backing and the deformation of the toe skin side accordingly.

8 to 11 show still another application example of the present invention. In this example, the inside of the shoe has a backing 46, an insole 50 and a frame structure 60.
Made of FIG. 8 is a sectional view of the shoe viewed from the side. Both the backing 46 and the insole 50 are made of non-stretchable Cambrelle. The insole 50 is
It is also supported by a non-stretchable insole 62 and a filler block 68. Upper 22 is shaped based on a commonly used fixed insole 70. As shown in FIG. 11, the frame structure 60 includes a frame 61 serving as a joint mechanism, which serves as a basis for performing girth adjustment. The material of the frame 61 is preferably plastic such as extruded polypropylene and has a thickness of about 0.03 to 0.04 inch (0.76 mm to 1.0 mm). The frame 61 has notches at 69 parts, and these notches serve as a bridge. The bridge portion acts as a hinge when the spring 72 is applied with force, thereby moving the frame in the left-right direction. The spring is a fastener 70 and
Attached to the frame by 71. If possible, the spring material is preferably made of stainless steel. As described above, the frame structure 60 is composed of the frame 61, the cut line 69, the spring 72, the fasteners 70 and 71, and the like. When the bridge is not created, the frame is divided and divided, and a space is provided between the divided frames. In this case, the length of one divided frame may be considerably short, or the number of divided frames may be reduced. Another method is to attach a spring 72 to the insole 62 that supports the insole. In this case, the fastener 74 is used to center the filler block 68 so that the frame moves in the left-right direction in a well-balanced manner. The insole 50 has an extended peripheral edge and surrounds the frame 61. Then, the folded back end portion is joined to the lower portion of the frame by an adhesive or heat radiation bonding. The backing 46 attaches to the frame structure. To do this, first place the instep 22 in a shoelace and use a jig to hold the frame in a fully expanded condition. In this state, the lower end of the backing 46 is attached to the peripheral end of the insole 50 with a bonding agent and attached to the entire frame structure. When the installation is complete, remove the jig. Also, the upper end of the backing 46 is attached to the instep 22 by stitching or adhesive, as shown. The instep part 22 is shaped according to the standard type fixed insole 70 by a conventional method. Finally, the lower end of the instep part 22 is cut off and attached to the unit sole with an adhesive or the like. Other sole configurations may be incorporated as desired. FIG. 9 is a sectional view of FIG. 8 viewed from the front, in a state where shoes are not worn. FIG. 10 assumes that the girth size of the person wearing the shoes is slightly smaller than the maximum girth size of the shoes.

12 and 13 are yet another application of the present invention. Although it is functionally the same as the example of FIGS. 8 to 11, in the case of FIGS. 12 and 13, the cam 78 is used to perform girth adjustment. That is,
By changing the girth size by turning the cam 78 by hand from the inside of the shoe and adjusting the tension of the spring 87. A cable extends from the rear end of the spring 87. This cable passes through the cam follower wheel 82 and connects to the insole 44 at the fastening point 43. The cable emerging from the spring tip acts on the girth backing structure, allowing the shoe to automatically fit the foot for different girth sizes. First, when the cam 78 is turned using the screw 76, the cam follower wheel 82 moves according to the radius of the cam groove 80. Then, the girth size is adjusted according to the tension applied to the spring 87. Cam follower
82 also moves a vertically moving metal plate attached to the back of the insole to vertically suppress the movement of the cam follower wheel 82. If necessary, the metal plate may be extended to the grommet 74 to harden the midsole portion between the cam follower wheel 82 and the grommet 74.
It prevents the insole 44 from twisting vertically when adjusting the girth.

There is also a method of adjusting the girth completely manually without using a spring in the above structure. In this case, the cable extends directly from the grommet along point 88. The cable passes through the cam follower 82 and stops at the fastening point 43. With this structure, the cam is manually adjusted to
Adjust the girth size by changing the distance between the 61 left and right frames. Although not shown in the figure, the girth size can be adjusted by either the manual method or the automatic method by applying the left-right spring 72 of FIG. 11 to the manual method. Alternatively, instead of a cable, a spring and / or a cam may be installed at the constricted part of the foot.

14 to 16 show still another application example. Figures 14 to 16
Is functionally similar to FIGS. 12 and 13. However, compared to other application examples, it can be made relatively inexpensive, which is preferable when the cost is limited. The shoe 90 shown in FIG. 14 is a typical tube type moccasin loafer, but this structure can be applied to other types of shoes. Upper portion 92 of shoe 90 is made of leather or a similar material. Consists of plug skin or tip
94, toe skin 100, toe skin backing 98 or plug skin backing 9
It is composed of 8a etc. The plug skin or tip 94 is
Double stitched with the toe skin 100 by hand-sewn 96.
The material for the back of the toe skin and the back of the plug skin is preferably spandex that extends in the left-right direction along the girth portion. HL Warshow &Sons's Spundura in New York
Is particularly sturdy and durable. The backings 98 and 98a are secured to the instep 92 by stitching at several points. In other words, as shown in the figure, the plug skin is 91, the plug skin backing is 91a, the cuff skin is 91b, and the heel is 91c, and they are firmly fixed by hand sewing. The lining 98 is sewn to the intermediate bottom 102 together with the toe skin 100 by the Littleway method 106. The unit shoe sole 104 is attached to the intermediate sole 102 with cement.
As the material of the intermediate sole 102 and the shoe sole 104, a sheet material or a mold material made of commonly used leather, plastic, rubber or the like is used. Finally, the removable insole 106 is inserted into the shoe 90 for comfort and durability.

FIG. 15 assumes that a person wears shoes with little or little need to adjust girth size. Upper 100 is partially fastened to backings 98 and 98a, while the other parts are spaced from the backing. Therefore, it deforms according to the height and width of the foot of the person wearing the shoe.

In FIG. 16, the backings 98 and 98a completely overlap the instep and plug skins. Therefore, the contour of the shoe matches the last model of the shoe when the shoe was made. FIG. 16 assumes that there is a person with a large girth size, and the girth size of the shoe is maximized.

The backings 98 and 98a are preferably made of stretchable fiber material. However, using other materials or mechanisms,
A structure can be created between the foot and the instep that allows the girth size to be adjusted. In this case, make sure the shoes fit at least the bulging part of the big toe. For example, air and / or other gases, gels, flowable substances or elastic plastic foam etc. should be placed in a bag made of a sealed or sealable plastic or plastic-like material. Then, there is a method of adjusting the girth by changing these amounts. Resilient plastic foams include closed cell thermoformable polyesters based on polyurethane foam. This is the United Form Products, Inc. of Georgetown, Massachusetts.
ited Foam Products Corp.). Other plastic foams may have a density of 2 # / cubic foot or less. Alternatively, the elasticity of the plastic foam may be used to directly adjust the girth. In this case, the plastic foam is backed with a slightly elastic cloth or lint. In order to properly adjust the girth with this method, at least the groin of the big toe, neck, instep, etc.
Adjustment width of 1/4 inch (0.635 cm) is required. To provide such a range of adjustment and proper compression, the backing thickness must generally be greater than the thickness applied for the toe skin backing. In other words, the thickness of the cloth and plastic foam, including 3/8 "(0.95cm) to 1/2" (1.27cm) before compression, and 1/16 "after compression.
Must be larger than an inch (0.16 cm) or 1/8 inch (0.32 cm). However, this width is too large, and there is a risk that there will be a gap between the tip line of the shoe and the foot. To minimize or eliminate this gap,
It is necessary to thin the part that touches the tip line of the groin, neck, instep, etc. of the big toe and form the contour of the plastic foam appropriately. That way, it looks
You can make shoes that fit even if you do. Next, an application example for correctly forming the contour of a plastic foam will be given.

There are various ways to properly shape the contours of plastic foam. For example, it is possible to use a plastic foam as it is, mold it by skiving, or use a plastic foam sheet material to remold it. However, for maximum efficiency at a minimum cost, and for application to all types of shoes, it is better to use thermoformable plastic foam. The types, including the ones already mentioned, are heated from 260 ° F to 300 ° F for 8 minutes to 12 minutes.
What can be processed if it is processed in minutes is preferable. The simplest method is to use a knitted fabric that is backed by a polyurethane foam sheet material that is thermoformable. In this case, first insert a 3/8 inch (0.95 cm) to 1/2 inch (1.27 cm) thick polyurethane foam knit cloth into the finished shoe and fit the shoe on it. The girth size of the shoe shape fits the foot with the smallest girth size for that shoe. After inserting the last, warm the shoe in an oven and / or pour hot oil or other liquid into the last to warm it. The portion of the polyurethane foam having a low compression rate formed by this heat treatment brings about an appropriate girth adjustment.

Although not shown in the figure, another application example is to use a small leaf spring. In this method, a leaf spring is inserted between the backing that covers the constricted side of the shoe and the instep, and girth adjustment is performed. Leaf springs are punched from a flat spring pawl with a thickness of approximately .010 inches (0.075 cm). This leaf spring is bent in advance so that the plug part (upper part of the upper part) is lowered and the upper part side spreads outward so that it fits a person with a small girth size.
Then, when a person with a large girth size is present, the plug portion becomes high, and the instep side is pulled inward while resisting the pressure of the leaf spring.

All of the applications described thus far allow the shoe to automatically fit the foot by adjusting the girth size between the groin of the big toe and the instep. These applications can also be applied to conventional shoe structures, so loafers, boots, slip-ons, and
It can also be used for this kind of shoes.
