Abstract
A shoe pad structure having an air chamber, particularly a shoe pad structure having an air chamber with cushion effects and applicable to the heel or ball on a shoe sole, comprising a flexible unit installed in an air chamber composed of two flexible plastic films with depressed centers thereof, characterized in that: the flexible unit is installed in the center depression of the air chamber, forming a ring-shaped buffer air chamber at the rim of the flexible unit in the air chamber, thereby enabling better cushion effects to prevent possible injury from exercise.
Description
- 1. Field of the Invention
- The present invention relates to a shoe pad structure having an air chamber, particularly a shoe pad structure having an air chamber with cushion effects and applicable to the heel or ball on a shoe sole.
- 2. Description of the Prior Art
- Due to better living standards in recent years, people have placed an increasing emphasis on their physical health. As a result, it has become a fad for people to engage in sports or exercise, which has resulted in increasing cases of injury during exercise or sporting activities. Most injuries sustained during exercise or sport are caused by either insufficient warm-up or poorly designed sports shoes. Insufficient warm-up can be corrected by the person doing the exercise, but poor design of sports shoes will have to be addressed by manufacturers. To date, the shoe industry has spent an extended period of time researching a design to prevent injury during sports activities or exercise. Most designs have divided a sports shoe pad into a pad unit and an air pad, the air pad serving to withstand and buffer the gravity of the user. In most cases, the air pad is installed in the heel of a shoe where most part of a body weight falls during exercise. Conventional air pad structures involve primarily a
support block 12 installed in anair chamber 11 composed of twoplastic films 10. Thesupport block 12 is a serial combination of a specified number of hard and hollowplastic blocks 13, thesupport block 12 filling the space in theair chamber 11. - However, while conventional air pad structures in athletic shoes do have a buffer effect and are widely adopted in the industry for use by the general consumers. In actual application, it does have the following shortcomings:
- 1. In the conventional shoe's air pad structure, the
support block 12 fills the space in theair chamber 11, so there is but a slight buffer distance between the flexibleplastic films 10 on upper and lower sides and thesupport block 12. As a result, when the user jumps up and down on a surface, it produces a large compression force from the user's heels. So, the flexibleplastic films 10 on the upper and lower sides of theair chamber 11 are compressed by that downward force to directly press against thesupport block 12 by the heels, resulting in the direct impact of the heels on thesupport block 12. Also, because thesupport block 12 is composed of several hard and hollowplastic blocks 13 in serial combination, injury can easily be sustained during sports activities. - 2. Furthermore, due to the fact that there is just a slight buffer distance between the
support block 12 and the flexibleplastic films 10 on upper and lower sides, after a certain period of use of the air pad, the flexibleplastic films 10 on upper and lower sides of thesupport block 12 will experience flexible fatigue caused by compression force from the heels. As a result, the flexibleplastic films 10 on upper and lower sides of theair chamber 11 are pressed tightly against thesupport block 12, losing their buffer effect. So the heels of the user will directly come into impact thesupport block 12 during sports activities and suffer injury. - The objective of the present invention is to provide a type of shoe pad structure having an air chamber with a buffer effect and applicable to the heel or ball on a shoe sole, comprising of a flexible unit installed in an air chamber composed of two flexible plastic films having slightly depressed centers, particularly the flexible unit is installed in the center depression of the air chamber, forming a ring-shaped buffer air chamber at the rim of the flexible unit in the air chamber, thereby providing better buffer effect, to prevent injury during sports and exercise activities.
- For full understanding of the structure, characteristics and applicability of the present invention, please refer to the following description of the preferred embodiment and drawings.
-
FIG. 1 is a perspective exterior view of a prior art. -
FIG. 2 is an exploded view of the present invention. -
FIG. 3 is a section view of the present invention. -
FIG. 4 is a perspective exterior view of the present invention. -
10 plastic film 11 air chamber 12 support block 13 plastic film 20 plastic film 21 air chamber 22 flexible unit 23 plastic block 24 buffer air chamber - Please refer to FIGS. 2 to 4. The present invention is a shoe pad structure having an air chamber, particularly a shoe pad structure having an air chamber providing buffer function, applicable to the heel or ball of a shoe sole, comprising an
air chamber 21 consisting of two flexibleplastic films 20 with slightly depressed center parts, containing aflexible unit 22. Theflexible unit 22 is a flexibleplastic block 23, or a serial combination of more than one flexibleplastic block 23. Theflexible unit 22 is installed in the center depression of theair chamber 21, forming a ring-shapedbuffer air chamber 24 at the rim of theflexible unit 22 in theair chamber 21. - Because of the special structural design of the present invention as described above, the present invention has the following characteristics in application:
-
- 1. Because of the present invention of shoe pad structure, the
flexible unit 22 is installed at a central depression of theair chamber 21, forming a ring-shapedbuffer air chamber 24 at the rim of theflexible unit 22 of theair chamber 21, theflexible unit 22 being installed at the center of the ring-shapedbuffer air chamber 24, having a clearance on an upper and lower part thereof, so when a user jumps down on a hard surface, the force pressing onto the user's heel can be absorbed by thebuffer air chamber 24, thereby avoiding direct impact of the user's heel onto theflexible unit 22, and reducing the possibility of exercise injury. - 2. Furthermore, due to the shoe pad structure in the present invention, the
flexible unit 22 is installed in the center depression of theair chamber 21, forming a ring-shapedbuffer air chamber 24 at the rim of theflexible unit 22 in theair chamber 21, so even after an extended period of use of the shoe pad unit, thebuffer air chamber 23 is capable of maintaining an appropriate buffer distance, though the flexibleplastic film 10 wrapping the upper and lower sides of theflexible unit 22 may have flexible fatigue caused by long-time compression from the downward force of the heel, thereby maintaining excellent flexible effects.
- 1. Because of the present invention of shoe pad structure, the
- It is to be understood that the preferred embodiment and design drawings described above are for reference purposes, and shall not be a basis to restrict the scope of claim of the present invention, and that all equivalent modifications or variations made without departing from the above description shall be included in the following claim.
