Description

M243061 V. Creation Description (i) [Technical Field to which the New Type belongs] This creation relates to the improvement of a shoe structure, in particular to provide a heel cushion with a shock-absorbing cushioning effect, so that the heel position is provided with a shock-absorbing cushioning effect. The elastic air cushion effectively relieves the pressure on the heel when walking or standing for a long time. [Previous technology] Taiwanese's feet are wider and shorter than those in Europe and the United States. Therefore, choosing a pair of shoes that are both popular and healthy and suitable for you can fully enjoy walking. For teachers or hotel doormen who have been standing for a long period of time due to their occupations, they have become a member of the plantar fasciitis community. The so-called "plantar fasciitis" is generally known as heel pain, long bone spurs on the soles of the feet, or inflammation of the floor. Plantar fascia is a layer of tissue located on the sole of the foot that extends forward from the calcaneus behind the sole to the toes. The plantar fascia plays a very important role in the function of the foot, it helps to maintain the arched structure of the foot, and also helps to maintain the stability of the foot as the foot advances. There are many causes of plantar fasciitis. Improper training methods, inappropriate shoes, and excessive walking or training may cause the plantar fascia to be overused. Flat and high arched feet are more likely to be caused by abnormal feet. He was tired and injured. The most important thing in treating plantar fasciitis is to remove any factors that may cause an undue load on the plantar fascia to create a good healing environment. Proper rest, improved training style or environment, wearing suitable shoes, raising heels (use hard materials to increase by about one centimeter), appropriate physical therapy or cooperation

How to actively self-care to avoid plantar fasciitis is very important, and choosing appropriate air cushion shoes to elastically absorb shock, support the arch of the foot, and protect the arch air chamber to reduce the pressure on the foot and increase the comfort of the foot will also Is an important way of health. The air cushion is like a shock absorber of the body, which can prevent the body from being damaged by pressure shock when walking or exercising; although the general air cushion shoes can achieve the ability to reduce the weight of the shock, the thickness of the air cushion deeply affects the shock absorption capacity. There are many air cushion shoes, but not many can achieve excellent shock absorption. In particular, it is limited by the positive relationship between the thickness of the cushion and the ability to absorb shock. Therefore, air-filled shoes in the workshop are mostly limited to shoes with thick soles such as sports shoes, rest shoes or shipwreck shoes. For gentlemen's shoes worn by men or women's wear High-heeled shoes, because it avoids too heavy soles from affecting the overall appearance, rarely has air cushion function. For example, US Patent No. 5, 2 1 8, 0 5 6 discloses an elastic air cushion structure "Elastomers", which is preset on the midsole 20 (lower η ter 1 ayer) of the shoe with respect to the axillary and heel bone positions of the foot. The grooves 2 6 and 2 8 (recesses), and the sheet-shaped elastic air pockets 2 2 and 2 4 (shock-absorbing insole pads) are built in the grooves. However, because the sheet-shaped elastic disc is positioned in the groove by adhesive bonding, the bonding place will often fall off and shift with the use of time. If it is not adjusted immediately, the discomfort of the anti-trace foot will be felt. In addition, since the elastic air cushion is made of a thin and soft material, the elastic cushion can provide a relatively limited shock absorption effect based on the proportional relationship between the thickness of the cushion and the shock absorption capacity.

M243061 V. Creative Instructions (3) For another example, the US Patent No. 4,9 1 8, 8 3 8 discloses another elastic air cushion structure rShoe sole having compressible shock absorbers ", which is a cylindrical shock absorbing element 2 (aircy 1 inder) is placed in a circle hole 1 2 1 (circu 1 arrecess) preset at the heel 1 2 (so 1 eunit). However, if the cylindrical shock-absorbing element has a poor connection with the round hole due to long-term use, the cylindrical shock-absorbing element cannot guarantee contact with the heel bone at the most correct vertical angle, and it will also cause the so-called foot discomfort, meanwhile, The cylindrical shock-absorbing element can only provide point contact with the heel bone, so the shock-absorbing effect it can provide is also quite limited. [New content] The applicant of this case is a professional manufacturer of air-cushion shoes. In view of the existing shortcomings of the conventional products mentioned above, it is striving to develop a heel air cushion with shock absorption and cushioning effect. That is, the main purpose of this creation is to provide a heel cushion with shock-absorbing cushioning effect. A preset groove is attached to the heel portion of the outsole of the shoe to accommodate the cushion assembly. The cushion assembly is composed of a rigid fixed frame and A soft air cushion body is formed; wherein, a U-shaped dovetail groove is provided on the inner edge of the fixed frame for the U-shaped dovetail periphery protruding from the central belly of the air cushion body to the sides to be inserted into the dovetail groove, and the central belly of the air cushion body faces upward The one-piece micro-projection top plane is used to directly contact the heel to withstand the downward pressure from the heel, while the bottom surface of the air-cushion body's central abdomen and one-piece micro-projection bottom plane is mounted on the bottom of the heel groove, as The upward support area of the air cushion body after compression. Make the heel press the sole at the maximum pressure position, and set an elastic air cushion with shock absorption and cushioning effect to relieve walking or standing for a long time.

[Implementation method] The following descriptions and drawings are examples disclosed based on the characteristics of this creation, so that the structural technology and characteristic range of this creation can be more easily understood. Please refer to the first to third figures. The preset grooves (not shown) of the heel portion 11 of the outsole 1 are used to receive the air cushion assembly. The air cushion assembly is made of EVA, It consists of a rigid fixed frame 2 made of TPU or PE and a soft air cushion body 3 made of PU, EVA or GEL. Among them, a 'horse-shaped horseshoe-shaped fixed frame 2 has a U-shaped nine bird tail on the inner edge. Slot 2 1 Air cushion body 3 Central abdomen 3 1 Perimeter-shaped dovetail perimeter protruding from both sides of the pressure equalizing area 3 1 1 Insert the U-shaped dovetail groove 2 1 and locate the air cushion body 3 Central abdomen 3 1 The integrally formed top surface of the microprojection 3 2 pressure area is used to directly contact the heel to withstand downward pressure from the heel, and the central abdomen of the air cushion body 3 1 is integrally formed with the bottom surface of the microprojection 3 3 is in contact with the bottom of the groove of the heel, and the 俾 serves as an upward support area after the air cushion body is compressed. As shown in the second figure, when the air cushion assembly inserts the air cushion body 3 with the central abdomen 3 1 of the U-shaped dovetail protruding to the sides 3 1 1 into the U-shaped dovetail of the inner edge of the horseshoe-shaped fixed frame 2 according to the above combination. After the groove 21, the top plane 3 2 and the bottom plane 3 3 of the air cushion body 3 extending upward and downward will remain the same plane as the top surface 2 2 and the bottom surface 23 of the horseshoe-shaped fixed frame 2. When the entire air cushion assembly 3 is placed in the groove of the heel 1 1 of the outsole 1 as shown in the third figure, the top plane 3 2 of the air cushion body 3 directly receives the downward pressure from the heel.

M243061 V. Creation instructions (5) The downward pressure is hindered by the counterforce of the bottom plane 3 3 of the air cushion body 3 and the upward supporting force is turned to the central belly 3 of the air cushion body 3 1 and the U-shaped dovetail peripheries 3 1 1 on both sides of the air cushion body are diffused to achieve the purpose of shock absorption. Because the air cushion body of this creation is indeed positioned in the horseshoe-shaped fixed frame, and the horseshoe-shaped fixed frame is accommodated in the heel groove, the air cushion body will have no problem of foot displacement due to long-term use. Because the air cushion system carries the heel on the entire top plane, the contact area and the total volume of the air cushion body will provide the best shock absorption effect.

Based on the above, it can be seen that this creation creates an excellent air cushion function with a very streamlined structure, so that the elastic cushion with shock absorption and cushioning effect can achieve the purpose of reducing weight and shock, which is of great health significance, and its practical effect is beyond doubt, However, this creation has never been published in the market or seen in other publications. It has actually complied with the provisions of the Patent Law and has filed a patent application in accordance with the law.
