CUSHION PAD
The present application relates to a cushion pad, which has flexibility. The cushion pad comprises an outer foot arch portion, an inner foot arch portion and a foot arch groove. The outer foot arch portion is formed by extending from one end of the cushion pad to the other end of the cushion pad, and the outer foot arch portion comprises a middle foot portion and a heel portion; the middle foot portion is disposed in the end of the outer foot arch portion; the heel portion is disposed in the other end of the outer foot arch portion that is opposing the middle foot portion and the heel portion is connected to the middle foot portion.
This application claims priority from Taiwanese Application No. 105212213, titled “Cushion Pad,” filed on Aug. 11, 2016, the contents of which are incorporated herein by reference in their entirety.
FIELD OF THE INVENTIONThe application relates to a shoe liner, in particular, it is a cushion pad placed in shoes.
BACKGROUND OF THE INVENTIONIn earlier ages, in order to protect feet from being hurt by rough ground, people wore shoes to protect their feet. Later on, as people's living conditions improved, shoes became required to not only protect people's feet but also to have desirable shape, style and comfort. No matter how people are walking or standing, their feet are always their necessary support. Accordingly, feet bear the pressure of overall human body weight. In particular, when people are wearing flat shoes or low-heeled shoes, the location which bears the most body weight is the rear part of foot. As a result, in the case when the soles or insoles of the shoes are very thin, the pressure generated when people are walking on ground will be applied on their feet. After a long period of time, this may result in various foot diseases, such as plantar fasciitis, foot peripheral nerve pain, foot joint pain, foot swelling and inflammation, etc.
In order to address the issues mentioned above, the existing technologies in the art typically use a whole piece of insole to increase the thickness of the bottom of shoes, which can only create a certain comfort for a people who wear such shoes. However, it is noted that such flat insole is unable to provide a support to feet arches on the bottom of the foot. In addition, such flat insole may also result in a very stiff shoe bottom, which prevents the shoe bottom from closely supporting the structure of human foot bottom. Accordingly, such insole makes it difficult for feet to engage in flexible movements and activities.
SUMMARY OF THE INVENTIONIn order to address the issues mentioned above, one aim of the present application is to provide a cushion pad to reduce the interaction between feet and the ground or between feet and a shoe bottom during walking.
For the foregoing purpose, the present application provides a cushion pad, which has flexibility. The cushion pad comprises an outer foot arch portion, an inner foot arch portion and a foot arch groove. The outer foot arch portion is formed by extending from one end of the cushion pad to the other end of the cushion pad, and the outer foot arch portion comprises a middle foot portion and a heel portion; the middle foot portion is disposed in on end of the outer foot arch portion; the heel portion is disposed in the other end of the outer foot arch portion that is opposing the middle foot portion and the heel portion is connected to the middle foot portion. Moreover, the inner foot arch portion is disposed on the cushion pad and is adjacent to the middle foot portion of the outer foot arch portion; the foot arch groove is disposed between the middle foot portion of the outer foot arch portion and the inner foot arch portion.
Preferably, each of the outer foot arch portion and the inner foot arch portion comprises an air pad, and the air pads have been disposed within the outer foot arch portion and the inner foot arch portion, respectively. More preferably, the cushion pad further comprises a connection path. The connection path has been disposed in the foot arch groove. The connection path functions to communicate the air pad within the outer foot arch portion with the air pad within the inner foot arch portion.
Preferably, the cushion pad is made from a material of thermoplastic polyurethane (TPU) elastomer.
In order to achieve the aim above provided, the present application further provides a cushion insole, which comprises the cushion pad described above, wherein the cushion pad may be disposed on the cushion insole in a protruding manner, disposed on the cushion insole in a recessing manner, disposed within the cushion insole, or disposed below the cushion insole.
For the cushion pad provided in the present application, the shape of the outer foot arch portion corresponds to a human foot's mid and rear parts, and the inner foot arch portion closely supports a human foot's inner foot arch, which helps to support the foot bottom, as well as disperse the pressure applied on the person's feet. Accordingly, it is able to reduce the incidence of plantar fasciitis. In addition, the air pad within the outer foot arch portion and the air pad within the inner foot arch portion are able to absorb the resilient force applied by the ground during walking. Therefore, the present application provides a cushion pad that is able to reduce the interaction between a walker's feet and the ground or between the walker's feet and a shoe bottom.
These and other features, aspects and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying figures where:
