Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a footbed, and particularly to a footbed providing good ventilation and anti-distortion. The present invention also relates to a method for making the footbed.

[0003] 2. Description of the Prior Arts

[0004] Most of the conventional footbeds are made of ethylene-vinyl acetate copolymer (EVA). The manufacturing cost of footbeds can be reduced remarkably due to the low-cost EVA. However, the EVA footbeds have many drawbacks such as lack of ventilation and being impermeable to water. Accordingly, while wearing shoes with the EVA footbeds, the wearer's feet are enclosed in shoes, which causes discomfort of the wearer and generates foot odor due to the lack of ventilation of the EVA footbeds. Besides, when the wearer's feet sweat, sweat remains on the surface of the footbeds easily due to the EVA footbeds being impermeable to water, which makes the wearer's feet suffer from moisture and thus makes the footbed prone to growth of bacteria. As a result, the chance is increased for the wearer to get skin infection such as athlete's foot. Furthermore, the EVA footbeds are not anti-distortion due to the low recovery rate and the softness of EVA. Accordingly, after EVA footbeds are worn for a period of time, the EVA footbeds deforms, which results in negative effects on the wearer such as poor posture.

[0005] In addition, in order to increase the rigidity of the EVA footbeds so as to prevent undesirable deformation, injection molded heel cups made of polyurethane (PU) are laminated on the bottom surface of the rear heel area of the EVA footbeds. However, the PU heel cups still have drawbacks such as yellowing and decomposition after a long period of time. Besides, PU heel cups easily generate toxicity during the decomposing process, which is severely harmful to the wearer's health. Also, the EVA footbeds with PU heel cups still lack ventilation and are impermeable to water. Furthermore, the EVA footbeds with PU heel cups are not integrally formed, that is, EVA footbeds with PU heel cups are manufactured through multiple processes. Accordingly, the manufacturing cost of the EVA footbeds with PU heel cups is increased and the industrial applicability of the EVA footbeds with PU heel cups is reduced.

[0006] To overcome the shortcomings, the present invention provides a footbed and a method for making the footbed to mitigate or obviate the aforementioned problems.

[0020] According to the present invention, the elastic polyester staple fiber is capable of increasing the rigidity of the fabric of vertical fibers.

[0021] According to the present invention, the polyester staple fiber containing rubber is capable of increasing the recovery rate of the fabric of vertical fibers.

[0022] According to the present invention, the definition of the recovery rate is the extent to which the fabric of vertical fibers recovers after compression.

[0023] According to the present invention, the recovery rate of the footbed is higher than 70%. Preferably, the recovery rate of the footbed ranges from 70% to 90%.

[0024] According to the present invention, the fabric of vertical fibers is a fiber web having vertically aligned structure, wherein the definition of the vertically aligned structure is that majority of fibers are oriented perpendicular to the surface having the largest area of the fiber web.

Preferably, the temperature of the heat source ranges from 160.degree. C. to 200.degree. C.

[0026] According to the present invention, the definition of "integrally formed" is that during the course of heating the fabric of vertical fibers, the rigid shell and the soft body are simultaneously formed. Accordingly, after heating the fabric of vertical fibers, the rigid shell and the soft body are integrally formed.

[0027] Preferably, the rigid shell has a protective portion protruding from a rim of the middle portion of the shell body and connecting to the supporting portion, the protective portion has an inner face and an outer face opposite to the inner face, wherein the shell body, the protective portion and the supporting portion form a space, and the bottom face of the soft body is laminated with each inner face of the rear portion, the middle portion, the front portion, the supporting portion and the protective portion.

[0028] Preferably, the rigid shell has a protective portion protruding from each rim of the middle portion and the front portion of the shell body and connecting to the supporting portion, the protective portion has an inner face and an outer face opposite to the inner face, wherein the shell body, the protective portion and the supporting portion form a space, and the bottom face of the soft body is laminated with each inner face of the rear portion, the middle portion, the front portion, the supporting portion and the protective portion.

[0029] Preferably, the middle portion of the shell body is an upward arch toward the soft body for fitting the foot arch formed in the middle of a foot sole of a human.

[0030] Preferably, the footbed has a fabric layer attached to the top face of the soft body.

[0031] Preferably, the footbed has a foot pad disposed between the soft body and the fabric layer and at a location corresponding to the rear portion of the shell body.

[0032] Preferably, the footbed has a foot pad disposed between the soft body and the fabric layer and at a location corresponding to the front portion of the shell body.

[0033] Another main objective of the present invention is to provide a method for making the footbed, which comprises steps of:

[0034] providing a fabric of vertical fibers;

[0035] providing a mold, wherein the mold has a shape corresponding to the shape of the footbed, and the mold has a heating surface;

[0036] placing the fabric of vertical fibers into the mold to abut against the heating surface;

[0037] heating the heating surface of the mold to a temperature ranging from 160 to 200.degree. C. to heat the fabric of vertical fibers, and then the footbed is obtained; and

[0038] wherein the rigid shell is formed between the soft body and the heating surface.

[0039] According to the present invention, in the step of providing a fabric of vertical fibers, the thickness of the fabric of vertical fibers ranges from 10 to 25 mm.

[0040] According to the present invention, in the step of heating the heating surface of the mold to a temperature ranging from 160 to 200.degree. C. to heat the fabric of vertical fibers, the time of heating the fabric of vertical fibers is, but not limited to, between 30 and 60 seconds.

[0041] Preferably, the step of heating the heating surface to heat the fabric of vertical fibers includes heating the heating surface of the mold to a temperature ranging from 160 to 200.degree. C. to heat the fabric of vertical fibers and applying a pressure to the mold simultaneously, and then a footbed is obtained.

[0042] According to the present invention, the time of heating the fabric of vertical fibers and applying a pressure to the mold simultaneously is, but not limited to, between 30 and 60 seconds.

[0043] According to the present invention, the higher the temperature of the heating surface of the mold and the longer the time of heating the fabric of vertical fibers and applying a pressure to the mold, the thicker the rigid shell. For example, but not limited to the following description: a fabric of vertical fibers with a thickness of 13 mm is provided; the heating surface of the mold is heated to 170.degree. C. and the time of heating the fabric of vertical fibers and applying a pressure to the mold simultaneously is 40 seconds, and a footbed is obtained, wherein the thickness of the rigid shell of the obtained footbed is 1 mm while the thickness of the soft body of the obtained footbed is 12 mm. A relative example such as a fabric of vertical fibers with a thickness of 13 mm is provided; the heating surface of the mold is heated to 180.degree. C. and the time of heating the fabric of vertical fibers and applying a pressure to the mold simultaneously is 60 seconds, and a footbed is obtained, wherein the thickness of the rigid shell of the obtained footbed is 2mm while the thickness of the soft body of the obtained footbed is 11 mm

[0044] Preferably, after the step of providing a fabric of vertical fibers, the method comprises a step of providing a fabric layer and then laminating the fabric layer with the fabric of vertical fibers. Hence, the obtained footbed has a fabric layer attached to the top face of the soft body.

[0045] Preferably, the step of providing a fabric layer and then laminating the fabric layer with the fabric of vertical fibers includes providing a foot pad and then laminating the foot pad with the fabric of vertical fibers to obtain a fabric of vertical fibers with the foot pad; providing a fabric layer and then laminating the fabric layer with the fabric of vertical fibers with the footpad. Hence, the obtained footbed has a foot pad disposed between the soft body and the fabric layer and at a location corresponding to the rear portion of the shell body.

[0046] According to the aforementioned structure, the advantages of the footbed of the present invention are as follows:

[0047] 1. Because the rigid shell and the soft body of the footbed of the present invention are integrally formed by heating a fabric of vertical fibers and also because the rigid shell is rigid, the rigid shell is anti-distortion, such that the footbed of the present invention does not distort easily, which extends the lifespan of the footbed. Besides, due to the supporting portion, the footbed can protect the heel of the wearer and avoid a heel strike while walking. Thus, the footbed provides higher heel stability. Furthermore, the soft body and the rigid shell provide good ventilation and are permeable to water. Accordingly, the wearer's feet are kept fresh and cool while wearing a pair of shoes with the footbeds inside and thus feet odor is prevented. Even if the feet sweat, the surfaces of the footbeds do not become wet, which prevents the growth of bacteria and prevent any infection. In addition, the rigid shell and the soft body of the footbed are made of a heated fabric of vertical fibers, wherein the fabric of vertical fibers is a fiber web having a vertically aligned structure. Hence, the footbed has good elasticity, high recovery rate and provides high heat insulation, which improves the comfort of wearing the footbed and keeps the feet warm during the winter. Also, after the footbed is worn for a period of time, the footbed will not collapse and will not become compressed and deformed. Hence, the lifespan of the footbed is extended.

[0048] 2. Because the material of the fabric of vertical fibers is polyester staple fiber, the footbed will be free from yellowing and will not decompose to generate toxicity after the footbed is worn for a period of time. Hence, the footbed of the present invention is a safe product.

[0049] 3. Because the rigid shell has a protective portion, the footbed can support the forefoot and the mid-foot well.

[0050] 4. Because the middle portion of the shell body is an upward arch toward the soft body, the footbed supports the foot arch well and thus provides excellent stability for the feet. Hence, wearing shoes with the footbeds is extremely comfortable.

[0051] According to the aforementioned steps, the advantage of the method for making the footbed of the present invention is as follows:

[0052] The rigid shell and the soft body of the footbed of the present invention are integrally formed through the step of heating the fabric of vertical fibers.

[0053] Accordingly, other additional steps such as adhering a heel cup to the rear portion of the footbed is not needed. Thus, the method for making the footbed of the present invention is extremely simple to reach the purpose of manufacturing a footbed having a rigid shell and a soft body integrally formed. Accordingly, the industrial applicability of the method for making the footbed of the present invention is enhanced remarkably.
