TWM508929U - Reformation of a replaceable uppers of offloading shoe of outsole structure - Google Patents

Abstract

According to the article, used therapeutic footwear which showed lower foot pressure, therefore therapeutic footwear is useful to reduce new ulceration. So this creation was to continue the concept of the replaceable uppers of offloading shoe[1], and further took into account the practical application of additional the offloading insole's height. Thus this creation was to reform the outsole structure of a replaceable uppers of shoe.

Description

Improved sole structure of foot sole decompression shoe with replaceable upper and sole

Due to the previously replaceable upper and lower sole decompression shoe 17[1], please refer to Fig. 3, which is a one-piece cloth upper 18, which is matched with the male and female devil's felt for the bonding of the upper and the sole. The bonding action needs to be combined with the devil felt 18L on the lower edge of the upper layer of the upper, and the upper edge of the sole is combined with the devil felt 21L. Therefore, the height of the modular sole 21 is related to the width of the devil's felt. Felt, the height of the modular sole 21 will increase, but if the decompression insole 13 is added, the overall height of the shoe will inevitably increase, which may cause potential risks when walking, so this The creative department is improving the sole structure of the detachable shoe.

The basic structure of the conventional shoe is generally composed of a sole, an upper, and an insole, wherein the sole is composed of a sole and a midsole, and the insole is designed to increase the comfort when worn. Therefore, the insole is placed on the sole and under the upper, so generally the groove space is reserved at the sole for directly placing the insole, and the use of the groove space is usually due to the functional factors and weight factors of the footwear. Or cost factors, etc., to further change the position or area of the original groove space, the conventional method is to make the outsole of the shoe as a groove facing upwards, or at the position of the outsole of different shoes. Patch to further utilize these The grooves that are facing upwards are listed here with some prior patent applications.

Elastic breathable sole structure 12 [2], please refer to Figure 1, and the method is to make the outsole of the shoe into a groove that is facing upwards, or to set a plurality of pockets at the outsole of the shoe, and A plurality of convex elastic bodies are placed on the outsole of the shoe, and an insole is placed thereon to provide a structure of an elastic and breathable sole, thereby achieving the effects of gas circulation, shock absorption and massage.

With environmentally friendly lightweight shoes 14 [3], please refer to Figure 1, which is to dig the ergonomic shape of the groove on the sole of the sole and place it on the flexible rubber. The wavy air cushion makes it lighter and longer.

The composite structure 15 [4] of the midsole and the insole, as shown in Fig. 2, is to set the PU outsole into a groove, thereby reducing the weight of the PU outsole and the midsole and the insole. Lightweight materials such as EVA form a composite body that is placed in the groove of the outsole of the shoe to achieve the design of lightweight shoes and provide elasticity and shock absorption.

Air cushion shoes 16 [5], please refer to Figure 2, which is designed to design a groove at the heel of the sole of the shoe, and place the air cushion material in the groove, and then set the outer insole and the inner cushion on the air cushion. Insole to achieve the effect of heel decompression.

Therefore, in order to make the footwear have different functionalities, the above-mentioned various types of patents all make good use of the space of the sole, and provide various grooves in the space and put different components in order to achieve the required functions, thus revealing The construction of the midsole and the outsole of the shoe can have an applicable space depending on the function of the shoe design and the intended use.

In view of this, the concept of making good use of the sole space has been in existence for a long time, and the concept of space application of the patent structure of the sole is not very different. The difference lies in the use of the shoe. The way, or the effect, and the starting point and use of the above patents are different from the detachable shoes of this creation, and it seems that the concept of applying the concept to the detachable combination of the sole and the upper is rare at present. Therefore, the purpose of the present invention is to solve the problem: after adding the sole decompression insole 13, the overall height preset by the sole decompression shoe 17 of the replaceable upper and the sole is not affected.

Since the bonding action of this patent needs to be combined with the devil felt 13L on the lower edge of the inner layer of the upper, and the devil felt 21L on the upper edge of the sole side, if the larger width of the devil felt is used, the height of the modular sole 21 will be Increasing, if the sole decompression insole 13 is added, the overall height of the shoe is bound to increase, so the method is to make the modular sole 21 into a full-foot groove sole 22 facing upward, which is concave The trough space 22a is just sufficient to accommodate the plantar decompression insole 13.

The design of the sole decompression insole 13 placed on the groove sole is divided into two types: detachable and non-detachable, and for the detachable manner, here is the devil felt 13L and the groove on the inner side of the back of the insole. The devil's felt 22L on the inner side of the sole is bonded, so that in addition to not increasing the overall height of the shoe, the decompression effect can be achieved, and the extra arch support can be provided due to the thickness of the devil felt, and The concept of a detachable shoe is simple and does not require complicated processes.
