Description

Background of the invention

Field of the Invention

The present invention refers to a functional footwear of a new concept, which adapts to the shape of the foot and provides a smooth sensation when walking.

Description of the prior art

Examples of regular footwear are shoes and socks.

A shoe according to the preamble of claim 1 is shown in US 6484419 B1. This document reveals a removable device to cover a shoe insole not attached to the insole.

The structure of a habitual shoe has developed in a different way depending on the use of it. The shoe generally includes an upper part, which covers the upper part of the foot and maintains the appearance and shape of the shoe, and a sole. On the sole, an outer sole that makes contact with the ground, a midsole located between the outer sole and an inner sole, a inner sole formed of a hard material to maintain the appearance of the shoe and that are stacked are sequentially stacked It works as a connection between the upper part and the sole, and an internal sole to hide residual threads, tacks and nails.

In addition, a regular sock, especially a short sock, includes an upper part that covers the upper part of the foot and a lower part that covers the sole of the foot.

In relation to the sensation when walking, a shoe has been suggested for the absorption of the impact due to the weight of a user while walking or exercising, by inserting an elastic body in the part between the inner sole texion and the sole exterior, or the formation of a midsole made of elastic material. However, in the structure of a conventional shoe, since the inner sole texion cannot be made of a soft and elastic material but can only be made of a hard material to function as a connecting part of the upper part and the sole, to maintain the shape of the shoe, and to fix the midsole or elastic body inserted in the midsole, there has been a limit in obtaining sufficient softness with which the shoe adapts to the shape of the foot in terms of the walking sensation

In the conventional shoe, the problem of the hard inner sole has been reinforced in general by the use of a midsole. However, even in this case, given that the shoe has a hard inner sole in the lower part of the midsole, there has also been a limit on obtaining sufficient softness in terms of walking sensation.

In the case of a short sock, an effort has been made to reduce the partial impact and improve the sensation during use by using double-woven fabrics at the bottom of these. However, since short socks assume the function of a shoe, there is still a limit to obtaining sufficient softness, in terms of the appearance of the sensation when walking, with which the sock adapts to the shape of the foot.

In the case of a functional shoe used for orthopedic purposes such as the correction, improvement or prevention of skeletal muscle problems, and assistance in rehabilitation, and for exercises of predetermined parts such as predetermined muscle reinforcement, objects, in general, are meet through a midsole of the footwear.

In addition, European Patent No. 0999764 and 1124462 disclose functional footwear for orthopedic purposes and for exercises of predetermined parts of the human body.

In the patents, a shape is defined that includes a transition portion from hard to soft between the foot and the floor surface. As a result, a continuous process is performed in a mandatory manner, which is based on the desired type when walking or an additional load is applied to one or more predetermined muscles when walking, so that the footwear corresponds to one or more necessary predetermined objects for a shoe user.

In addition, the aforementioned footwear has the purpose of simulating the sensation of walking, for example, on non-flat surfaces such as an area with sand, soils in the forest or a meadow, while being used on a flat surface such as a paved road , a smooth or concrete surface.

However, since the aforementioned functional footwear includes a hard texion inner sole or a separate hard structure to maintain the appearance of the footwear, there has been a limit in obtaining sufficient softness, in terms of the appearance of the sensation when walking, with which the shoe adapts to the shape of the foot.

In addition, since the functional shoe works as a mandatory therapy that requires a predetermined method of walking and a predetermined posture to the user, the user must maintain balance using the required locomotion organs such as muscles and skeleton. The method of walking or the regulation of the posture when walking is determined by using a hard or soft insert material that has a lower structure in a predetermined way. An orthopedist deliberately determines how the user should act and what attitude he should have and therefore determines the default form of the lower structure.

However, the predetermined shape of the lower structure may be unsuitable for individual symptoms and has a danger of requiring inadequate posture over a long period of time due to an improper diagnosis of an orthopedist.

In conventional footwear used for special functions, it is often necessary for footwear to adapt to individual walking methods and individual structures of locomotion organs to have an excellent effect on orthopedic objects or exercises for predetermined parts. However, in general, and as if a user selects an erroneous structure or an orthopedist makes an inaccurate diagnosis, functional footwear is not comfortable when they start to be used, they are difficult to use, and in the worst case they can misuse total discomfort. Such a situation arises when users need to adapt to footwear.

The users not only adapt to the footwear but the footwear adapts to the shape of the foot of the user and to his methods of walking in the footwear and in the inner soles texion, that are manufactured in leather or fabric by means of a simple method.

However, fiber, plastic and rubber, currently used as synthetic materials, have a basic limit in the adaptation of soft materials to the user's foot due to their characteristics and the structures of the aforementioned footwear.

In addition, it has been studied and tested through experiments that provide comfort at the user's foot and the maximum degree of freedom has a healing orthopedic effect through the user's movement sequence. This is related to a report indicating that people in rural countryside who walk barefoot on soft natural soil keep their locomotion organs much more fit than the inhabitants of cities that use standardized footwear.

Therefore, it is necessary to develop footwear with a new concept that suits the user to provide total comfort while walking and the maximum degree of freedom to the foot, even if some or all structures are abandoned to maintain the appearance of the footwear.

Summary of the Invention

Therefore, the present invention has been made to solve the aforementioned problems that occur in the prior art, and an object of the present invention is to provide footwear that has a simple structure and can give the feeling of walking barefoot on a Padded spongy or grassy layer like a soft carpet to provide total comfort to the user when walking.

Another object of the present invention is to provide footwear that can easily change the feeling one has when using it and the correction function when walking if necessary.

Another object of the present invention is to provide footwear that provides total comfort to the user when walking and the maximum degree of freedom to the foot.

The aforementioned objects are achieved with a shoe comprising the features of claim 1.

A conventional shoe, essentially, includes a hard texion inner sole or a hard structure to maintain the appearance of the shoe, but the present invention does not include a hard texion inner sole or a separate structure to maintain the appearance of the shoe in order to improve the appearance of the footwear. walking sensation

In accordance with the present invention, despite partially abandoning the appearance of maintaining the appearance of a shoe, the present invention not only has a relatively simple structure and can give a feeling of walking barefoot on a spongy padded layer or on grass like a carpet soft to provide

Total comfort to the user when walking, but can also give the maximum degree of freedom to the foot by adapting a part of contact with the foot to the shape of the sole of the foot.

The part that supports the foot also includes a cover that covers a part or all of the outer surface parts of the soft resilient padded layer and that fixes the soft resilient padded layer.

Depending on the structure, the resilient padded layer formed of an elastic body can be easily protected and received and fixed and the resilient padded layer (an elastic body received in a chamber, in the case where the cover forms the chamber) can be interchanged, having the appearance of the footwear the fixing section of the upper part of the foot and a cover that maintain the original shape.

The part that supports the foot includes a lower part formed on the outer surface of the cover to prevent the sliding movement of the footwear when it makes contact with the ground. The lower part is formed integrally with the cover forming the contact part with the floor of the cover in a thicker way than the other parts. In addition, the lower part can be formed by coating at least a part of the contact part with the floor of the roof.

The cover can be formed integrally with the resilient padded layer, or it can be formed separately and firmly adhered to the resilient padded layer by adhesive bonding, etc.

In addition, the elastic body uses an open elastic body, a closed elastic body or both.

Here, the open elastic body refers to an elastic body for example, a foam material or structure made of sponge, rubber or a natural / synthetic resin that contains air inside or in its structure, which has an elasticity property in the method of discharging air by applying pressure and pressing the elastic body, and recharging air by reducing the pressure.

In the case of forming a resilient padded layer that includes the open elastic body, if the elastic body is compressed, the air existing in an intermediate space of the material or structure can be transferred into the fixing section of the upper part of the foot, The user's foot reaches a state of ventilation due to the flow of air generated during the pressure and expansion of the air and also a feeling of smoothness when walking due to the elastic body.

Preferably, the resilient padded layer is divided into an upper part that includes at least one open elastic body and a lower part that includes a closed elastic body.

Thanks to the double structure of the resilient padded layer, the lower part provides a relatively stable elasticity property, and the upper part uses the elastic body open in such a way that the ventilation property of the footwear can be improved during the time when He is walking, using the air generated while the resilient padded layer relaxes and contracts.

More preferably, the elastic body that forms the resilient padded layer includes elastic particles inside.

According to the structure, the elastic particles inside the soft elastic body can function as a shock absorber that alleviates the phenomenon that the soft elastic body is pressed quickly when the footwear is worn, and prevents the sensation of the hard ground from transferring to the foot when The soft elastic body is subjected to maximum compression. In addition, the sensation of using the hunt or the sensation when walking can be regulated by adjusting the amount, size and type of hard elastic particles inserted when the elastic body is manufactured, thereby regulating the degree of compression and the maximum compression thickness.

Preferably, the present invention includes a lower part adhered to the outer surface of the part that supports the foot, to protect the part that supports the foot that includes the resilient padded layer and prevent sliding movement while making contact with the ground.

The lower part may be formed only in the part of contact with the ground but is not limited thereto. The lower part extends and covers at least a part of the front, rear, right and left sides of the foot to connect the part that supports the foot with the fixing section of the upper part of the foot additionally, or it extends to fix a part of or all the foot.

In addition, the fixing section of the upper part of the foot is formed of a soft material and is shaped like a short sock. The soft material includes a natural or synthetic fiber as in a regular sock and any material flexible enough to adhere to or detach from footwear, such as natural or synthetic latex and a synthetic resin.

Since the fixation section of the upper part of the foot is generally in the shape of a usual sock, it can easily adhere or peel off and the sensation when wearing footwear and the feeling of smoothness when walking, compared to footwear, can be maximized. conventional.

Preferably, the fixing section of the upper part of the foot is in the form of a short sock of a textile material and is adhered to the cover at the upper end of the foot to be formed, integrally, with the cover. In this case, the cover can be adhered by various methods such as sewing, adhesive bonding, etc. Especially if the material of the cover is the same as that of the fixing section of the upper part of the foot, the cover can be formed integrally with the fixing section of the upper part of the foot, or it can be manufactured separately and then adhere to the fixing section of the upper part of the foot by sewing, etc., so that it has the shape of a dual sock that has a reception space at the lower end thereof.

More preferably, a part of the connecting part of the fixing section of the upper part of the foot and the cover can be opened and closed to remove and change the resilient padded layer. In addition, the shape of the fixing section of the upper part of the foot is not limited to a sock and can be applied to various forms of shoes, sandals, etc.

bottom of the foot, a cover 3 formed integrally with the resilient padded layer 2 or adhered separately to the resilient padded layer 2 for fixing the resilient padded layer 2, and a bottom (not shown) formed in the contact surface with the floor to prevent the sliding movement of the footwear.

As can be understood in the preferred embodiment, since the present invention does not include a hard inner sole and a separate part to maintain the appearance of the footwear, which is different from a usual shoe, the feeling of the soft resilient padded layer 2 is transfers to the foot when walking, and therefore, the user feels the comfort of walking barefoot on a soft sponge, carpet or grass.

In addition, the lower part (not shown) to prevent the sliding movement of the contact surface with the floor of the part that supports the foot can be formed selectively. The lower part can be omitted if it is not necessary, depending on the material and shape of the resilient padded layer 2 or the place where the footwear is used. In case the lower part is omitted, the resilient padded layer 2 alone forms the part that supports the foot. In addition, if the cover 3 is applied to the footwear according to the present invention, the lower part may be formed integrally with the cover when the cover is formed, or it may be adhered separately to the surface of the cover that comes into contact with the ground

In addition, as described below, the lower part (not shown) can be extended upwards to fix the part that supports the foot with the fixation section of the upper part of the foot or can be used to fix the foot to the footwear when walking .

In the preferred embodiment of the present invention, the soft resilient material 2 can be fixed to the fixation section of the upper part of the foot 1 by one of the known connection methods such as joining with an adhesive, sewing and connecting with an element of Velcro fastener, a sliding fastener (or a closure), or a pressure fastener. In the case where the cover 3 is applied to the resilient padded layer 2, the resilient padded layer 2 can be adhered using a connection part of the cover 3 according to known methods. In addition, in some cases, the bottom (not shown) can be extended to adhere.

The fastening section of the upper part of the foot 1 comprises a soft material and can have various shapes such as a sock, rubber boot, sports shoe, sandal, chinel and the like according to its use. The material of the fastening section of the upper part of the foot 1 may include various materials such as soft rubber, fabric, a mesh, leather and the like.

In addition, a plurality of ventilation holes can be formed in the fixing section of the upper part of the foot and the design of the foot fixing part can be modified, for example, by the formation of a transparent window.

The resilient padded layer 2 is formed of a soft elastic body or includes the cover. And the elastic body material can be classified into an open elastic body and a closed elastic body, the open elastic body refers to an elastic body for example, a foam material or structure made of sponge, or a natural / synthetic resin containing air inside or in its structure, which has an elasticity property in the method of discharging air by applying pressure and pressing the elastic body, and recharging air by reducing the pressure, the closed elastic body refers to a elastic body for example, a filled body that is in the form of a closed bag that is filled with a filling material such as air, a fluid, and a gel or rubber with an elasticity property whose shape can only be changed by applying pressure and compressing the elastic body while no air or filler material is introduced or discharged. For the various embodiments of the resilient padded layer 2, one or both types of resilient bodies can be used.

The material and structure of the soft elastic body are selected such that the compression rate of the resilient padded layer is fifty to ninety percent if the footwear is worn.

In addition, a closed bag-shaped elastic body has a valve (not shown) such that the elasticity property can be varied, if necessary, by the discharge or filling of the filling material therein.

The flat shape of the resilient padded layer 2 generally follows the shape of the bottom surface of the shoe. The thickness (thickness of the resilient padded layer in the case where the bottom is not formed) of the resilient padded layer 2 varies according to the weight of the user and the elasticity property of the elastic body. In addition, as described above, the soft elastic body of the present invention has a compression rate of fifty to ninety percent when the shoe is worn. Therefore, according to the present invention, it is preferred that the thickness of the elastic body is at least 1 cm from the surface of contact with the ground, and at least 0.5 cm in the case that it is for children.

Foot adheres to each other through a part of the cover 3. The cover 3 can be integrally formed with or separately from the resilient padded layer 2.

By way of reference, in the connection structure, although the connection part is shown as a part of the cover 3 which extends, it can be a part which extends from a lower part (not shown).

Hereinafter, the connection structure of the fixing section of the upper part of the foot and the part that supports the foot will be explained in detail with reference to the drawings.

With reference to Figure 5a, the cover 3 of the resilient padded layer of the part that supports the foot is fixed and adheres to the fixing section of the upper part of the foot by joining or sewing to adhere the part that supports the foot including the padded layer resilient to the foot fixing part. On the outer surface of the cover 3 a part can be opened and closed to exchange the resilient padded layer by inserting and removing the resilient padded layer without separating the entire cover from the fixing section of the upper part of the foot.

In the preferred embodiment, although the part, which can be opened or closed using a sliding fastener 4, is formed in the heel part of the cover 3, it can be mounted on any surface according to the use and design of the footwear.

In the preferred embodiment, by using the part that can be opened and closed, the resilient padded layer 2 formed of an elastic body can be protected and received and fixed with additional ease and only the resilient padded layer can be exchanged, maintaining the appearance of footwear the original form.

Figure 5b is a view showing the state in which a part that supports the foot is detachably connected in the form of a chanclo by extending the upper part of the cover 3 of the part that supports the foot to cover and fix the upper part of the foot fixing part.

In the preferred embodiment, the fixing section of the upper part of the foot can be separated from the part that supports the foot by removing the cover in the form of a chanclo. During separation, the resilient padded layer 2 can be changed and only the fixing section of the upper part of the foot can be replaced by another or can be washed.

Figure 5c is a cross-sectional view showing the state in which the cover 3 extends to an ankle part on the upper part of the foot to be fixed and the part that supports the foot is fixed in the form of a dual sock.

In the preferred embodiment, the fixing section of the upper part of the foot can be separated from the part that supports the foot by removing the cover of the fixing section of the upper part of the foot as in the form of a pig. In addition, during separation, the resilient padded layer 2 can be changed and only the fixing section of the upper part of the foot can be replaced by another or can be washed.

In addition, in this case, as shown in the figure, a space can be formed in the heel part of the foot that is designed for ventilation.

Figure 5d shows a structure in which the part that supports the foot is fixed in the form of a dual sock by extending the cover to the ankle part on the upper part of the foot at the front of the foot to fix the cover . The back of the cover extends only to a heel part of the foot and adheres by sewing. In the structure, the resilient padded layer 2 can be exchanged by installing a sliding fastener at the rear end of the cover and by opening and closing only the heel part.

The connection structure is especially suitable for the case in which the foot fixing part and the foot supporting part are formed of a textile material or a soft rubber and have shapes such as socks.

Figure 5e shows the state in which a sliding clamping element 4 is mounted to the upper end of the cover 3 as a connecting part and the cover 3 adheres to the sliding clamping element mounted at the lower end of the fixing section from the top of the corresponding foot.

In the connection structure, if the sliding fastener is opened, the part that supports the foot is separated so that the resilient padded layer 2 can be interchanged. In the preferred embodiment, the sliding fastener 4 is formed in the resilient padded layer if the cover is not applied to the resilient padded layer.

With reference to Figure 5f, the lower part, the upper end of the cover, or the resilient padded layer adheres to the fixing section of the upper part of the foot 1 by the use of a Velcro fastener.

In the preferred embodiment, a Velcro fastener 5a is mounted only to the outer peripheral surface of the upper part of the part that supports the foot and adheres to a Velcro fastener 5b mounted at the lower end of the section of fixation of the upper part of the foot to prevent the feeling of use of the footwear is reduced due to the Velcro connection. In addition, the Velcro part can extend not only on the connecting surfaces of the foot fixing part and the part that supports the foot but also on the circumference of the side surfaces of the foot fixing part and the part that supports the foot to reinforce the connection using a Velcro tape 5c.

For specific embodiments, two connection methods can be used independently or together.

Figures 6a to 6g are seen to explain methods of forming parts that support the foot in accordance with the structures of the resilient padded layer 2, the cover 3, and the bottom 4 of the present invention.

Figure 6a shows a preferred embodiment including only the resilient padded layer 2. The resilient padded layer, which is an elastic body, can have a part for operation as a cover formed integrally on its outer surface during the process of manufacturing. In this case, according to the manufacturing method, the cover or a part that functions as a cover can be formed of the same material as the elastic body, thereby strengthening the mechanical friction of the external surface of the elastic body. The resilient padded layer can adhere directly to the fixation section of the upper part of the foot or can be used as an inserted material according to the embodiment. In addition, a lower part (not shown) that prevents the sliding movement of the footwear can be formed selectively on the ground contact surface.

In the case where the described cover is then applied, the cover may be integrally formed with the resilient padded layer when the resilient padded layer is manufactured. In the case where the cover is manufactured separately, it can be detachably adhered to the resilient padded layer and firmly fixed to the resilient padded layer by adhesive bonding, etc.

Figure 6b shows a preferred embodiment in which the cover 3 covers the entire elastic body. In this case, for example, the cover must be essentially a soft resilient film or membrane such as a thin rubber, resilient textile material, etc. In the preferred embodiment, the ground contact surface functions as a lower part making the ground contact surface thicker than the other parts when the roof is manufactured.

Figure 6c shows the case in which the cover 3 covers only the periphery of the upper surface of the resilient padded layer to minimize the change of sensation when wearing the footwear. Similarly, the ground contact surface becomes thicker than the other parts when the cover is manufactured.

The part of the cover, which covers the resilient padded layer, functions as a connection part when the fixing section of the upper part of the foot adheres to the cover by adhesive bonding, sewing, or Velcro, etc.

With reference to Figure 6d, the cover extends to the top of the resilient padded layer. An adhesion part such as a sliding fastener, a Velcro fastener, or a pressure fastener is mounted on the part of the extended cover that will adhere to the corresponding part of the fastener section of the upper part of the foot. The cover can be extended further to reach the fixing section of the upper part of the foot in the form of a chanclo or dual sock. Similarly, the ground contact surface becomes thicker than the other parts when the cover is manufactured.

Figures 6e to 6g show the cases in which the lower part 6 is formed separately on the surface of contact with the floor of the roof.

Figures 7a and 7b are perspective views showing preferred embodiments in which the resilient padded layer has divisions. In figure 7a the resilient padded layer is divided to the right and to the left of the foot. In Fig. 7b, the resilient padded layer is divided to the right, left, the front and back of the foot such that the resilient padded layer can be in the form of a matrix.

In this case, the cover (not shown) can have the same shape as the outer shape of the resilient padded layer 2 to receive the resilient padded layer 2, or it can receive the resilient padded layer, regardless of the shape of the padded layer resilient

In this case, the cover or a part that functions as a cover can be formed of the same material as the elastic body thereby strengthening the mechanical friction of the external surface of the elastic body according to the manufacturing methods. The resilient padded layer can adhere directly to the fixation section of the upper part of the foot or can be used as an inserted material according to the embodiment. In addition, a lower part (not shown) that prevents the sliding movement of the footwear can be formed selectively on the ground contact surface. In addition, the sensation when using the footwear and the corrective function when walking can be changed according to the user's requirements by adjusting the shape and / or materials of the divisions of the resilient padded layer.

Figures 8a and 8b show the structure of the cover 3 in which the resilient padded layer is manufactured by inserting resilient bodies into chambers formed in the divided cover 3. The cover forms a plurality of chambers that receive the resilient bodies and the Resilient padded layer 2 is formed by inserting the plurality of resilient bodies in the chambers. In this case, a cover covering (not shown) covering the open parts of the resilient padded layer is used selectively. In the case of using the cover of the cover, the cover of the cover is formed of a soft and ventilated material.

Figures 9 and 10 are seen to explain the compression rate in the case where the footwear is used, before and after the insertion of an insert material into the elastic body of the resilient padded layer.

In the case of forming the body of the resilient padded layer with foam material of a synthetic resin for example, polyurethane, the elastic body that includes the insert material can be manufactured by inserting polyurethane particles or granules during the foaming process to perform the Foam material shape. In addition, in the case of the closed elastic body in which a bag is filled with a fluid or gel, it can be manufactured by placing the elastic particles such as polyurethane granules before filling the liquid or gel in the bag.

Figure 9c is a graph showing the resilient repulsive force F as a function of changing the difference Δ between the thickness d1 of the resilient padded layer before using the shoe and the thickness d2 of the resilient padded layer after using the footwear in the case where a general elastic body is applied to the resilient padded layer.

Figure 10c is a graph showing the resilient repulsive force F as a function of changing the difference Δ d between the thickness d1 of the resilient padded layer before using the shoe and the thickness d2 of the resilient padded layer after using the footwear in the case where granules harder than a general elastic body are inserted inside the resilient padded layer.

Figure 9a shows that the resilient repulsion force is changed close to the fundamental thickness d1 of the resilient padded layer in a predetermined linear shape.

On the other hand, in the case of the resilient padded layer of Figure 10a, which includes granules harder than the elastic body material, the curve of the resilient repulsion force can be regulated according to the quantity and type of granules as in the graphic.

The drawings reveal only the cross sections for ease of understanding, but the present invention applies to resilient bodies that form resilient padded layers with different shapes.

The footwear according to the present invention has a simple structure and can give the sensation of walking barefoot on a spongy padded layer or grass like a soft carpet to provide total comfort to the user when walking.

Furthermore, according to the present invention, the sensation of using the footwear and the correction function can be easily changed when walking if necessary.

In addition, the present invention can provide total comfort to the user when walking and the maximum degree of freedom at the foot.
