Description

[Technical Field]

[0001] This invention relates to a shoe horn for shaping shoes that guides the heel of the foot into footwear such as shoes and sneakers (sports shoes), and is used with the foot still in the shoe to shape the shoe and protect the foot. [Background technology]

[0002] Traditionally, shoehorns have been constructed separately from footwear and typically held in the hand. While shoehorn-shaped guides integrated into the heels of footwear have been proposed and commercially available, these have drawbacks in appearance and usability, as they remain attached even when not in use. To improve usability, synthetic resin-made products with longer inserts are now commercially available and are attached to shoes or sports shoes (Figures 11 and 12).

[0003] As prior art, the following has been disclosed as a shoehorn that can be attached to a shoe. Patent Document 1 relates to a shoehorn that allows people who have difficulty putting their toes into their shoes to easily put on their shoes. It also discloses plan views of the spatula 4 of the shoehorn 1 according to an embodiment of the invention (Figs. 14 and 15). Patent Document 2 states that its problem is to provide shoes that can be put on and taken off easily and quickly without the need for a shoehorn or hands, that are comfortable to wear, and that look good in appearance, and discloses as its solution that "has a leaf spring 12 with one end attached to the inside of the heel part 4 of the shoe, and when not in use, the leaf spring 12 is separated from the heel part 4 and maintains an inclination with respect to the attachment point of the shoe, and when in use, as the foot is inserted into the shoe, it moves closer to the heel part 4 against the biasing force of the leaf spring 12" (Figure 13).

[0005] [Patent Document 1] Patent No. 7553734 [Patent Document 2] Japanese Patent Application Laid-Open No. 2010-142486 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the conventional shoehorns and shoes with leaf springs described above do not fit the shape of the shoe or the shape of the foot, and do not take into consideration the shoe's material for adjusting the shoe's shape or protecting the foot, particularly the heel cavity. In other words, the conventional shoehorns and shoes described above are made of synthetic resin, which is different from the shoe's material and does not adjust the shoe's shape. Furthermore, they are not sufficient for providing warmth or preventing foot sweating or odor inside the shoe (especially for bare feet). Particularly when wearing shoes barefoot, they need to retain the shape and temperature of the bare foot and feel one with the shoe. However, they have the problem of not matching the shape of the foot, especially the bare foot. In recent years, sports shoes have become more common even in business settings, but there has been no product that can address the sweating and odor associated with sports shoes. In addition, because ordinary shoehorns are separate from the shoes, they are easily lost; integrated shoehorns are cumbersome because they cannot be removed when not needed; they can damage the heel of the shoe or ruin the appearance; they cannot eliminate sweaty feet or odors; and the colors of shoes and socks and the skin color cannot be coordinated when wearing footwear barefoot.

[0007] The purpose of this invention is to provide a shoe horn for shaping shoes that has a structure that can be easily attached only when in use and easily removed when not needed, that can smoothly guide the heel of the foot into the heel part of the shoe when in use, but does not get in the way even when attached to the shoe (it fits the shape of the foot and protects it), is comfortable to wear, and also protects the foot by shaping the shoe. [Means for solving the problem]

[0008] The present invention is a shoehorn for guiding the heel of a foot into footwear such as shoes or sneakers (sneakers), and is characterized by comprising a concave heel recess that guides and protects the heel of the foot, and adhesive means such as adhesive tape or adhesive on the back side of the heel recess for attaching and detaching the heel of the footwear, the heel recess being positioned approximately vertically along the heel of the footwear and being detachably attached by the adhesive means. According to the present invention, the shoehorn for foot and shoe orthopedics of the present invention is provided with adhesive tape or adhesive for attaching and detaching to the heel part of the footwear, so that it can be attached to the heel part of the footwear and used as an integrated part with the shoe. The shoehorn is provided with a concave heel recess that guides and protects the heel of the foot, and it corresponds to the shape of the heel of the foot and the heel recess of the shoe, so that the heel can be smoothly guided into the heel part of the shoe, and it can be used without getting in the way even when attached to the shoe, and it can also adjust the shape of the shoe.

[0009] The present invention is a shoehorn for guiding the heel of a foot into footwear such as shoes or sneakers (sneakers), and is characterized by comprising a concave heel recess that guides and protects the heel of the foot, and a stepping sole extending from the heel recess that is stepped on by the heel-side sole of the foot, the heel recess being positioned approximately vertically along the heel of the footwear, the stepping sole having a larger recess than the heel recess and positioned at an angle downward and forward from the approximately vertical heel recess, so that it is stepped on by the heel-side sole of the foot. The shoe horn is designed to protect the sole of the foot (the heel side) and prevent the shoehorn from easily coming off the shoe. In other words, the shoehorn can be adjusted by simply stepping on it with the sole of the foot, without using adhesive tape or adhesive.

[0010] This device can be used as an instep cover to cover and protect the instep of footwear such as shoes and athletic shoes, and is characterized by the fact that the instep spatula (upper part of the instep) placed on the instep of the footwear and the adhesive means are detachably provided. According to the present invention, the instep cover can be used to cover and protect the instep of shoes such as sneakers and athletic shoes, and since the adhesive means is detachably attached to the instep spatula (upper part of the instep) arranged on the instep of the footwear, it can be easily attached and detached to the instep spatula (upper part of the instep) arranged on the instep of the footwear.The instep spatula is pressed and molded to match the shape of the instep of the footwear, and covers the instep to create a protective section.

[0011] This invention is characterized by being made of flexible plaster and / or fiber-reinforced plaster, and is molded into a concave shape with an appropriate curvature angle to fit the heel of the user's foot. According to this invention, flexible gypsum is suitable for applications requiring flexibility and shape change in the heel area according to walking posture, and if strength is required, it can be mixed with fiber-reinforced gypsum. In addition, the orthopedic shoehorn for feet and shoes of this invention is characterized by being made of synthetic cast material used as medical plaster cast material or splint material, or synthetic cast material that becomes like hard plaster after hardening, and is molded into a concave shape with an appropriate curvature angle to fit the user's foot. According to this invention, the shape of the shoe can be shaped and adjusted to suit the user's foot while providing appropriate protection (protection with a cast or splint in case of injury). In other words, the shoe can be shaped and adjusted to fit the user's foot while providing protection.

[0012] The present invention is characterized in that a front cover member made of fiber or fabric that covers the heel recess and the recess of the treading sole is attached in a replaceable manner. According to the present invention, the front cover member is replaceable, so that breathability can be maintained to prevent foot sweating and odor, and the cover can be replaced to deal with foot sweating and odor.

[0013] The present invention is characterized in that a rear cover member made of fiber or fabric that covers the heel recess and the treading bottom is attached in a replaceable manner. According to the present invention, the front cover member is replaceable, so that breathability can be maintained to prevent foot sweating and odor, and the cover can be replaced to deal with foot sweating and odor. [Effects of the Invention]

[0014] As described above, this invention provides a mounting structure and method for baseboards and wall finishing materials that can prevent deterioration and alteration caused by water intrusion and chemicals in facilities where the use of water and chemicals is expected, while maintaining the beauty of the joints between walls and floors and improving construction efficiency.

[0016] (First embodiment of shoehorn 1A for orthopedic foot and shoe) Figures 1(a)(b), 2(a)(b), 3 and 4 are perspective views (photographs) illustrating and comparing shoehorns 1A and 1B for foot and shoe shaping according to embodiments of the present invention. Each shoehorn has a concave heel recess 2 that guides and protects the heel of the foot, and an adhesive means 5 on the back side of the heel recess 2 for attaching and detaching the heel portion Sa of footwear S. The heel recess 2 protects the heel of the foot, guides and leads the heel to the heel of the shoe S, and shapes the heel of the shoe. The lower end 2a of the heel recess 2 stands on the bottom of the shoe S, and a protruding guide portion 3 is provided on the upper side of the heel recess 2. Therefore, when the heel of the foot is guided from the protruding guide portion 3, the foot is guided into the shoe S from the heel side via the heel recess 2, thereby protecting it. The back side of the heel recess 2 is provided with adhesive means 5 such as double-sided tape or pressure-sensitive adhesive for attaching and detaching the heel portion Sa of the shoe S. Figures 6(a) and 6(b) show a configuration in which double-sided tape 5a, 5a is placed in two locations, while Figures 7(a) to 7(c) show an arrangement in which double-sided tape or pressure-sensitive adhesive as adhesive means 5 is placed over almost the entire back side of the heel recess 2.

[0017] The shoehorn 1 for foot and shoe orthopedics of this embodiment is made of flexible plaster or fiber-reinforced plaster. This allows it to flex and change in response to the movement of the heel recess 2 of the foot, and is therefore designed to be worn especially with bare feet. The upper protrusion 3 may also be made of synthetic resin or metal. The tread bottom 4, which will be described later, is slightly larger than the heel recess 2 and is also formed with a larger recess. This is because it is necessary to provide angled protection for the bottom of the foot (the heel-side bottom). The stepping bottom 4 has a larger recess than the heel recess 2 and is inclined downward and forward from the heel recess 2, which is disposed almost vertically, making it easier to step on with the heel side bottom of the foot. In other words, it is shaped to correspond to the inclined posture of the sole and heel when walking.

[0018] A back cover 6 and a front cover 7 made of colorful fibers or fabrics are detachably attached to the inside of the heel recess of this shoehorn. In addition, a detachable adhesive tape or adhesive is attached to the back side of the heel recess 2, allowing it to be coordinated with the color of shoes, socks, or feet (skin color), and allowing for hygienic use to prevent feet and socks from getting sweaty. These cover members 6, 7 are preferably made of waffle fabric, gauze fabric (especially multi-layer gauze), which has overlapping layers that trap air and give the surface a soft, uneven feel, terry cloth, quilted fabric, and other fabrics that have an uneven surface that can bond with the shoe fabric (heel fabric) or cause the uneven surfaces to rub against each other.

[0019] A fabric-based, breathable front cover member 6 is replaceably attached to cover the heel recess and the stepping bottom. A back cover member is provided on the entire or part of the heel guide and stepping bottom, covering the back adhesive means. It can also be used as a regular shoehorn (to provide a foot-sliding effect).

[0020] In this invention, when worn in shoes, materials such as flexible gypsum are suitable for use in applications requiring flexibility and change in foot shape (worn barefoot), as they adapt to the shape and flexibility of the foot. Furthermore, when strength is required, it is also possible to use a mixed material (hybrid) with fiber-reinforced gypsum. Other examples of such materials include Lunacast®, which is used as a medical plaster cast or splint, and Polycast®, a synthetic cast material that hardens to resemble hard plaster and is used for fixation where greater strength and stability are required. Another suitable material is Polycast®, a synthetic cast material also used for medical purposes (plaster casts and splints). Lunacast® looks like bandage fabric, while Polycast looks like hard plaster once hardened. Lunacast, mentioned above, is a synthetic cast material that looks like gauze or a bandage and is used in medical settings as a plaster (splint) material to immobilize fractures, sprains, and other injuries. These synthetic cast materials are characterized by their construction, in which a flexible fabric such as polyester fiber is impregnated with a hardening resin. When used, the material is soaked in water and then wrapped around the body, where it hardens through a chemical reaction. Hardening typically begins within 5 to 10 minutes, reaching a practical hardness in approximately 30 minutes. Compared to plaster casts, Lunacast is lightweight, water-resistant, breathable, and highly durable. Before hardening, it is soft like a bandage and easy to handle. Polycast, mentioned above, is a synthetic casting material that hardens like hard plaster and is used for fixation requiring greater strength and stability. It is also a product used for medical purposes (plaster casts, splints), and is characterized by its gauze material containing polyurethane and polyester synthetic resins. It is used in the same way as Lunacast: it is wetted with water and then wrapped around the body to harden. After hardening, it becomes harder and has a plaster-like texture, allowing for firm fixation. It is typically used in areas subject to high loads or in cases requiring long-term fixation.

[0021] (Foot and shoe orthopedic shoehorn 1B of the second embodiment) The foot and shoe orthopedic shoehorn 1B of this embodiment is a shoehorn that guides the heel of the foot into footwear such as shoes or sneakers (sneakers), and is equipped with a concave heel recess 2 that guides and protects the heel of the foot, and a stepping sole that extends from the heel recess and is located on the bottom of the heel side of the foot to protect it (Figures 1(a)(b) and 2(a)(b)). The stepping sole 4 has a recess 4a that is larger than the heel recess 2, and has a large concave shape 4 that is recessed further back than the heel recess 2 in the approximately vertical position. The user steps on the stepping sole 4 with their foot in this large recessed state, so it will not fall off the shoe even without the use of an adhesive or the like.

[0022] As a method of use, the shoehorn 1B for shaping the foot and shoe, which has been heated to a predetermined temperature, is placed inside the shoe S, and then the user places the foot inside the shoe S, allowing the shoehorn to be shaped to an appropriate curve angle to suit the user's foot.

[0023] (Application example 1) The shoehorns 1A-1C for foot and shoe orthopedics of the present invention are composed of a shape-reversible thermoplastic resin. The shoehorns soften when heated to a predetermined temperature (55-60°C) and are molded to the appropriate curvature angle to fit the user's foot. A "shape-reversible thermoplastic resin" is a thermoplastic material that, even after being deformed, has the property of returning to its original shape (i.e., shape memory) when subjected to a certain stimulus (mainly heat). One representative example is polycaprolactone (PCL). Polycaprolactone (PCL) has a relatively low melting point of approximately 55-60°C, is flexible, soft at room temperature, has a slightly rubber-like elasticity, and is easily processable: it can be molded immediately upon application of heat. After cooling, it becomes a stable solid. It is also biodegradable and decomposes in vivo and in soil, making it suitable for environmental and medical applications. Therefore, it can be molded to the user's foot shape only once (after being molded to the desired shape), and the shape is maintained in a hardened state by leaving it at room temperature. This makes it possible to provide a shoehorn with a shape that is easy to use and specific to the user.

[0024] (Application example 2) The foot and shoe orthopedic shoehorns 1A-1C of the present invention can also be used as instep covers 1C that cover and protect the instep portion (Sa) of footwear such as shoes and sneakers (sneakers). The instep spatula (upper portion of the instep) Sa, which is placed on the instep (Sa) of the footwear, is detachably attached to the adhesive means 5 (Figs. 9(a)-(d)), 10(a)-(c)). The shoelace Sb pulls the shoehorns 1A, 1B on the rear side of the shoe S and the shoehorn 1C on the front side together, allowing the shoe S to be shaped and the foot to be protected (protected by a plaster cast). This type of use can be used interchangeably with the instep spatula (upper part of the instep) Sa placed on the instep of the footwear S, as their shape and pressing function are similar. Furthermore, since the adhesive means 5 is provided detachably, it can be easily attached and detached to the instep spatula (upper part of the instep) Sa placed on the instep S of the footwear S, and in the case of sports shoes, it can be attached and detached to the instep spatula (upper part of the instep) Sa to adjust the shape of the shoes S and protect the feet.

[0025] In the above-described embodiment, even if the heel of a shoe or footwear is stepped on (see symbol Sf in Figures 9(a) and 9(b)), the present invention is useful as a method for restoring this (the shoe shape can be reshaped). In other words, the shape of the heel recess 2 and the tread area 4 of the shoe can be neatly restored. Then, the foot can be smoothly inserted into the repaired shoe (the shoe shape can be reshaped), and walking can be continued. [Explanation of symbols]
