Description

shoes

The present invention relates to shoes, and more particularly, to assembling shoes.

Generally, shoes are tailored to specific uses, and people own many different types of shoes for different purposes. For example, different shoes are used for walking, hiking, athletics, or official events. Even if they belong to the same category, you need a lot of shoes, including hiking shoes that are suitable for snow, shoes that are suitable for wetlands, and lightweight shoes that are designed to be comfortable for long-distance hiking in dry terrain. It is. Similarly, even for formal footwear, various shoes with different colors and styles are used depending on the type of clothes and events.

Also, general shoes are molded with the upper part, the inner sole part, and the outer sole part all fixed. Therefore, it is generally impossible for the user to freely change the design and color of a single shoe. At present, a user owns a plurality of shoes and selects and uses one shoe in accordance with the design and color of clothes to be worn and a bag to be carried each time.

The following solutions have been proposed for such issues. U.S. Patent No. 6,057,051 discloses an athletic shoe having an elastic upper portion that can be inserted into or removed from a shoe sole, heel leather and toe core. However, the tip and heel leather parts are mechanically connected to the sole and are not changeable. A further deficiency of this shoe is that only the upper part can be changed.

Patent Document 2 discloses a shoe having an upper portion and a bottom heel portion that are connected to each other by a male / female groove fastener. The upper portion of the shoe includes an upper rear portion and an upper threaded hole. The inadequacy of this shoe is that the tread is connected to the insole and therefore cannot be changed independently. A further inadequacy of this shoe is that only the upper part can be changed.

Furthermore, Patent Document 3 discloses a reversible shoe having a removable medium. The upper part of this shoe is connected to the outsole. The deficiency of this shoe is that the upper part is on the midsole and has a zipper to support the upper part in place. The zipper is at least partially visible and fragile. Another deficiency of this shoe is that the shoe tip is formed with the midsole and is not interchangeable. A further inadequacy of this shoe is that the upper part is not completely replaceable.

It is preferable to have a locking portion at the tip of each first ribbon.

The shoe kit of the present invention is characterized by comprising any of the above outer soles, inner soles, upper socks, and a first ribbon.

Furthermore, the method for assembling the shoes using the shoe kit of the present invention is such that the inner sole is inserted into the upper sock and placed on the outer sole, and the outer sole and the inner sole or the outer sole and the inner so as to embrace the inner sole. The sole and the upper socks are connected by a first ribbon. Thus, by joining with the first ribbon, the inner sole follows the movement of the foot during wearing, the foot is less likely to slip within the inner sole, the fit is improved, and the stability is increased.

Furthermore, the method for assembling a shoe using the shoe kit of the present invention is such that the inner sole is inserted into the upper sock and placed on the outer sole, the first ribbon is placed on the upper sock, and the inner sole is hugged. The outer sole and the inner sole, or the outer sole, the inner sole, and the upper sock are joined with a first ribbon so as to be inserted. Thus, by joining with the first ribbon, the inner sole follows the movement of the foot during wearing, the foot is less likely to slip within the inner sole, the fit is improved, and the stability is increased.

The material of the outer sole that corresponds to the bottom material of general shoes is not limited, but it is made of leather, synthetic rubber or synthetic resin, or synthetic rubber or synthetic resin. However, it may be vulcanized using natural rubber as a raw material.

The inner sole of the present invention corresponds to a common insole of shoes, and the upper sock of the present invention corresponds to an upper material of a general shoe, and the materials of the inner sole and the upper socks are not limited, Natural leather, artificial leather, synthetic leather (woven fabric, knitted fabric, non-woven fabric or other fiber sheet coated with a resin such as urethane or nylon), natural fiber, or synthetic fiber can be used.

The first ribbon used in the present invention is an important member that connects the outer sole and the inner sole to the wearer's foot, and the material thereof is not limited, but is made of natural leather, artificial leather, synthetic Made of leather (fabric sheets, knitted fabrics, non-woven fabrics, etc., coated with a resin such as urethane or nylon), natural fibers, or synthetic fibers can be used. In particular, fibers are preferable from the viewpoint of strength, durability, and flexibility, synthetic fibers are particularly preferable, and woven fabrics are more preferable from the viewpoint of dimensional stability. Further, the material of the second ribbon provided for facilitating the assembly operation and for easy wearing can be adopted from those described in this paragraph.

The shoe of the present invention is composed of a plurality of parts, and has the following effects.
Since a shoe manufacturer does not need equipment for assembling shoes, the equipment can be simplified. In particular, a general shoe requires a long experience and dexterity in the work of bonding or sewing the toe portion or the heel upper material to the sole due to its complicated three-dimensional shape. Such experience and dexterity are not necessary. Moreover, what is necessary is just to provide what provided the function specialized for each component, and management of the process from design of a material and a shape to manufacture is easy. Furthermore, since the shape of each part is a comparatively simple shape compared with the shoe which is a product, the loss of material is reduced.

The seller of the shoes of the present invention can sell the three parts of the outer sole, the inner sole and the upper sock separately, so that the stock quantity can be greatly reduced. That is, if you sell shoes as a finished product, it is necessary to have the stock amount multiplied by the number of design types and the number of sizes, but according to the present invention, the stock amount may be the addition of each part. Because. For example, if there are 10 types of upper material designs and 5 types of outer soles with different shapes and hardnesses, the number of combinations will be 50, for example, from 24 cm to 28.5 cm, which is a typical shoe size. If it is arranged in 0.5cm increments, it becomes 10 sizes, and a total of 500 pairs of stock is required. However, according to the present invention, since the inner sole can be used in common, it is 10 pairs for each size, and the design difference of the upper socks and the number of sizes are multiplied by 100 pairs, the difference in the shape and hardness of the outer sole, By multiplying the number of sizes, it is only necessary to have 50 parts, that is, a total of 160 parts in stock. In particular, if the upper socks have an appropriate stretch property, they can be used in several sizes, and the stock quantity can be further reduced. In addition, since the parts are not bulky compared to the finished product, they can be sold in a bag and suspended, and the store and inventory space can be reduced.

The purchaser of the shoes of the present invention can wear unique shoes by changing the combination of parts in accordance with individual preference. Moreover, by changing only the upper socks, many kinds of designs can be changed, which is economical. In addition, the inner sole and upper socks can be washed, so it is always clean. Furthermore, if necessary, the inner sole can be comfortably worn on a rainy day without getting wet directly by simply replacing the inner sole with a waterproof one that covers the toe and heel. it can.

Embodiments of the present invention will be described below, but it goes without saying that various changes and modifications can be made without departing from the technical scope of the present invention.

1 to 4 are schematic views of components as an example of the shoe of the present invention. In FIG. 1A, reference numeral 1 denotes an outer sole, 2 denotes a long first ribbon, and a middle portion in the longitudinal direction of each of a plurality of first ribbons 2 is fixed to the outer sole 1. Each first ribbon 2 has an annular ring-shaped locking portion 3 at both ends in the longitudinal direction. As shown in FIG. 1A, the method of fixing the intermediate portion of the first ribbon 2 to the outer sole 1 with the ring-shaped locking portions 3 at both ends of the first ribbon 2 is efficient in assembling work. However, it is also possible to use a shorter ribbon, one end of which is bonded to the outer sole or fixed by other methods, and the other end has a ring-shaped locking portion. The rear end portion of the outer sole 1 also has a second ribbon 4 fixed to the outer sole 1. A hook-and-loop fastener (male) 4 a is provided on the inner surface of the second ribbon 4. Alternatively, as shown in FIG. 1B, the first ribbon 2-1 may be formed into an annular shape, and both ends thereof may be bonded to the outer sole 1-1 or fixed by other methods. Moreover, since the surface fastener 5a (female type (refer FIG. 6, FIG. 7)) is also provided in the part of the inner sole 5 corresponding to the surface fastener (male type) 4a, the inner sole 5 is thereby attached to the outer sole 1. It is preferable because positioning at the time of mounting is facilitated and fine adjustment of positioning is facilitated. Thus, by connecting the outer sole and the inner sole with the hook-and-loop fastener, a fixed state can be made even when the foot is pulled out, which is preferable. The hook-and-loop fastener 4a of the second ribbon 4 may be female, and the hook-and-loop fastener 5a provided on the inner sole 5 may be male. In short, it is preferable that the corresponding portions of the second ribbon 4 and the inner sole 5 are provided with hook-and-loop fasteners, because a fixed state can be made even when the foot is pulled out. The second ribbon 4 can be removable and replaceable.

2 (a) and 2 (b), 5 and 5-1 are inner soles having an inner surface suitable for inserting a foot. The inner soles 5 and 5-1 have at least an inner shape that conforms to the outer shape of the foot, can cover the toe portion and the heel portion, and can be covered on a rainy day if it is waterproofed. This is preferable because the feet do not get wet. In addition, it is preferable that the inner soles 5 and 5-1 have a mesh shape because of excellent air permeability. The inner soles 5 and 5-1 do not cover the entire foot, but may have a planar shape that touches only the back of the foot as in the case of a general inner sole, but the shape retention and appearance when not worn In consideration of the above, it is preferable to have a shape that wraps the toe portion and the heel portion of the wearer. Assuming a wearing scene that does not get wet, it is preferable to use a highly breathable mesh material because the feeling of stuffiness is reduced.

3 (a) and 3 (b), 6 and 6-1 are upper socks into which the inner soles 5 and 5-1 can be inserted, respectively. It should be noted that the general upper material is disposed only on the instep portion of the foot, and it is not common for the upper socks 6 and 6-1 used in the present invention to have a shape that conforms to the outer shape of the foot. It has a sock-like shape and wraps the soles of the feet. Upper socks 6, 6-1 are preferably sock-like bags. Further, a general sock has a sewing line above the toes. However, when used for the upper socks, the design property becomes a problem. Therefore, it is more preferable to arrange the sewing lines on the toe back. It is preferable that a plurality of openings 6 a are provided at the bottom of the upper socks 6 and a plurality of openings 6 b are also provided at the upper portion of the upper socks 6. The

openings

6a and 6b serve as holes through which the first ribbon 2 is passed. 7 is a shoelace.

The upper sock is preferably a fiber structure because it is easy to follow the outer shape of the foot and is excellent in design. If the upper socks 6, 6-1 are made of knitted fabric, it is preferable from the viewpoints of comfort and design and ease of handling during washing, and can be knitted according to the shape of the inner sole. It is excellent in that it is possible to follow the inner sole without tracing the shape. Further, if the upper socks 6 and 6-1 are circular knitting, it is preferable for reducing the manufacturing cost. Further, if the upper socks 6, 6-1 are made of polyester fiber, it is preferable in terms of durability. In addition, for shape retention, a fused yarn is partially inserted into the upper socks 6 and 6-1, and is fused with an adjacent yarn by heat treatment, or a resin coat or film lamination is partially applied. It is also preferable to increase the hardness.

As shown in FIG. 5A, the inner sole 5 is inserted into the upper socks 6, and as shown in FIG. 5B, the inner sole 5-1 is inserted into the upper socks 6-1.

As shown in FIG. 6, the longitudinal middle portion of each first ribbon 2 is fixed to the outer sole 1 with a flange 8. In addition, it is good also as a shape which can fix a ribbon at the time of the injection molding of an outer sole, without using such a collar 8, or as mentioned above, the 1st ribbon 2 is adhere | attached on the outer sole 1, or it couple | bonds by sewing. May be. Alternatively, the outer sole 1 may be provided with a ring-shaped locking portion or the like so that the first ribbon 2 can be coupled to members such as the outer sole and the inner sole through the ring-shaped locking portion. First, the second ribbon 4 is inserted between the upper sock 6 and the inner sole 5 through the opening 6c formed in the upper sock 6, and the hook-and-loop fastener 4a provided on the second ribbon 4 (see FIG. 1A). If the hook-and-loop fastener 5a (see FIGS. 6 and 7) provided on the inner sole 5 is coupled, it is preferable because the subsequent assembly operation becomes easy. In order to improve the comfort, the width of the second ribbon 4 is not less than 5 mm and not more than 30 mm, and the stress at 5% elongation of the second ribbon 4 is 0.3 to 2.5 N / mm. Preferably, it is 0.5 to 2.0 N / mm. If the toe portion of the outer sole 1 is provided with a ribbon with a hook-and-loop fastener similar to the second ribbon 4 with the hook-and-loop fastener at the rear end, and is combined with a pair of hook-and-loop fasteners provided on the inner sole 5 Further, it is more preferable because the assembly work becomes easier. As shown in FIGS. 7, 8, and 9, each first ribbon 2 fixed to the outer sole 1 passes through an opening 6 a (see FIG. 6) formed in the upper sock 6, so that the upper sock 6 and the inner sole 5 It is inserted between.

As shown in FIG. 10, the shoelace 7 is inserted through the ring-shaped locking portions 3 formed at both ends in the longitudinal direction of the first ribbon 2 to tie the shoelace 7. FIG. 11 shows a state where the upper socks 6 are removed from FIG. Although the shoe of this embodiment has the 1st ribbon 2 and the shoelace 7, the 1st ribbon 2 can also serve as the function of the shoelace 7. For example, using a very long first ribbon, the long first ribbon is fixed to the heel provided on the outer sole 1, and both ends of the long first ribbon are tied or buckle If the function of the shoelace 7 shown in FIG. 10 or FIG. 11 is achieved by fixing with, for example, the shoelace 7 becomes unnecessary. In addition, since an assembly operation will be time-consuming if the long first ribbon is used, it is preferable to use a shoelace so that the tightening force can be easily adjusted. Moreover, as shown in FIG. 10, when most of the first ribbon 2 is disposed below the upper socks 6, the design is improved. However, the first ribbon 2 is used for reasons of wearer's preference and design. The upper socks 6 may be disposed on the upper side.

As shown in FIG. 11, since the first ribbon 2 is wound so as to tighten the foot from above the inner sole 5, if the width of the first ribbon 2 is too narrow, the foot is locally compressed. On the contrary, if the width of the first ribbon 2 is too large, it will be difficult to walk because it acts as a resistor when trying to bend the foot during walking. Therefore, the width of the first ribbon 2 is preferably 3 mm or more and 30 mm or less and wider than the shoelace. Furthermore, if the first ribbon 2 has appropriate elasticity, the comfort is further improved. Therefore, the stress at the time of 5% elongation of the first ribbon 2 is preferably 0.3 to 2.5 N / mm.

In addition, the stress at the time of 5% expansion | extension in the said 1st ribbon and the 2nd ribbon is a constant speed extension type test according to JIS-L-1096: 2010 8.14.1 JIS method (A method cut strip method). Using a machine, measure the load when the elongation rate becomes 5% at a gripping interval of 200 mm in the length direction of the ribbon at a tensile speed of 200 mm / min, and calculate the stress as follows. Value.
S: Stress at 5% elongation (N / mm) = L / W
L: Load at 5% elongation (N)
W: Ribbon width (mm)
Since the stress at the time of 5% elongation of the first ribbon and the second ribbon is 0.3 N / mm or more, the force to restrain the foot is sufficient, and it is difficult for the foot to swim in the shoe, 2.5 N / mm By being below, the wearer does not feel uncomfortable such as numbness without the force of tightening the foot being too strong. More preferably, the stress at 5% elongation of the first ribbon and the second ribbon is 0.5 to 2.0 N / mm.

As shown in FIG. 12, each first ribbon 2-1 fixed to the outer sole 1-1 is disposed so as to cover the upper sock 6-1 from the outside, and each first ribbon 2 shown in FIG. As shown in FIG. 13, the shoelace 7 is inserted into the base portion 9 of the annular portion -1 and tied.

The shoe of the present invention can select a suitable configuration according to various actual situations by changing the combination of the parts, so it can moisturize daily life and send a comfortable daily life. It is an invention that contributes significantly to the fashion industry.
