Description

Insole structure

The present invention relates to an insole structure, in particular to an insole structure having a more disassembled upper pad. When the upper pad is dirty, the upper pad is replaced or the upper pad is cleaned, and the insole structure is not required to be cleaned or discarded.

The main point of the functional insole is that it is the support of the arch, or the design of the breathable anti-foot, or the combination of the shock-absorbing material to reduce the pressure on the sole of the foot, and the insole that appeals to the function is more expensive. Insole is expensive, and in order to make a functional insole, it usually causes an increase in the number of manufacturing processes, resulting in cumbersome production, and in order to achieve one of the functions, it is usually necessary to discard other functions, such as: breathable insole, usually the support effect is not Good, therefore, the conventional insole is difficult to concentrate on one. Furthermore, the insole supported by the arch is usually recommended by a professional physician for the correction of the arch, so that the cost of the corrective insole is higher, and in order to correct the arch, it is necessary to abandon the functions of shock absorption, ventilation and ventilation. There is a need for improvement.

Although the conventional insole has a plurality of functions, the face layer is usually not removed from the foam layer of the main body, because the face layer is tightly bonded to the foam layer, and when the face layer is damaged or dirty, The user can usually only discard the insole and replace it, or brush the entire insole. This will cause the foam layer to absorb moisture and get wet, which will reduce the service life of the insole.

Furthermore, it is necessary to stack and fix the insole of the multi-layer material in order, and to maintain the smoothness of the surface, which is very cumbersome and time-consuming in the production process. In particular, if other functions are to be added, the structure must be improved, and the production process is cumbersome and inevitable. Many working hours lead to increased costs, which in turn causes consumers to spend more to purchase, resulting in a financial burden on consumers.

Other technical contents, features, and effects of the present invention will be apparent from the following detailed description of the preferred embodiments.

Please refer to Figures 1, 2 and 3 for an exploded and perspective view of the first embodiment of the present insole structure. As can be seen from the figure, the main pad 1 and the lower pad 2 are mainly included, and the upper pad 1 is soft or a rollable or flexible or deformable elastomer, fabric or foam or fabric bonded to a foam or a soft breathable leather, the upper mat 1 having a top surface 11 and a bottom surface 12, the top surface 11 is a comfortable surface, which has the characteristics of anti-slip and moisture wicking and deodorization, and the bottom surface 12 is provided with a positioning member 121. In the embodiment, the positioning member 121 is a matte surface. The upper pad 1 can be set as a solid body or a hollow body according to requirements. If it is a hollow body, the upper pad has a filling space, and the filling space can be filled with a filler having shock absorbing and diffusing characteristics.

The underpad 2 comprises a foam 21 composed of a plurality of independent cells which are not connected to each other, and the foam 21 is a chemically cross-linked foam (XPE Foam or XPP Foam) or Made of cross-linked foam (EPE Foam or EPP Foam) with a foaming ratio of 2-40 times, the thickness is 2mm, 3mm, 4mmc or 5mm, the bottom end surface of the foam body 21 has an anti-slip element 22, the anti-slip element 22 can be a synthetic rubber, and the anti-slip element 22 is provided with a non-slip pattern, and The top surface of the bubble body 21 is provided with a bonding member 23, which in this embodiment is a reticular fiber burr wire which can be fully or partially bonded to the top surface of the foam body 2. The length of the reticular fiber burr 23 must be smaller than the thickness of the upper pad 1 to prevent the reticular fiber burr 23 from penetrating the top surface of the upper pad 1, and the reticular fiber burr 23 is disposed obliquely upward or straight.

The foaming ratio of the foam 21 is preferably 2, 3, 4, 5, 6, 7, 8, 8, 9, 10, 11, 12, 13 or 14 Multiple, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 times, 32 times, 33 times, 34 times, 35 times, 36 times, 37 times, 38 times, 39 times and 40 times.

The bottom surface of the upper pad 1 is coupled to the top surface of the lower pad 2, so that the positioning component 121 of the upper pad 1 and the bonding component 23 of the lower pad 2 are tightly coupled, and the upper pad 1 is fixed to the lower pad 2, in the present embodiment. In the example, as shown in Figs. 4 to 6, the reticular fiber burr 23 penetrates into the matte surface of the upper mat 2, and once the upper mat 1 is subjected to X (left-right direction) or Y-axis (front-rear direction) When the force is applied, the upper pad 1 does not slide due to the restriction of the reticular fiber burr 23 . However, as shown in Fig. 6, when the upper pad 1 receives the force in the Z-axis (up and down direction) direction, it can be easily pulled upward, so that the upper surface of the upper pad 1 is separated from the reticular fiber burr 23, and The lower pad 2 is detached.

Referring to Figures 7 and 8, the underpad 2 can be first molded into a shape of the sole (corresponding to the position of the arch of the arch). Since the upper pad 1 has deformable characteristics, when the upper pad 1 is coupled to When the lower pad 2 is placed, the upper pad 1 is shaped like the top surface of the lower pad 2 as shown in Fig. 8 (having a shape of a foot arch).

Referring to Figures 9, 10 and 11, the positioning member 121 of the bottom surface of the upper pad 1 and the bonding member 23 of the top surface of the lower pad 2 may be mutually felted devil felts, as shown in Fig. 9, the positioning element 121 and the coupling member 23 can be disposed on both sides of the upper pad 1 and the lower pad 2; or as shown in FIG. 10, the positioning member 121 and the coupling member 23 can be elongated and disposed on the upper pad 1 and below. The locating element 121 and the splicing element 23 can be disposed near the front end and the rear end of the upper pad 1 and the lower pad 2, and other structures are the same as the first to eighth ends. The figures are the same and will not be described here.

Referring to FIG. 12, since the bottom surface 12 of the upper pad 1 and the top surface of the lower pad 2 are not completely tightly joined, a gap is formed between the upper pad 1 and the lower pad 2, and the slit is available for the airflow 3 to circulate. To achieve the purpose of heat dissipation.

Referring to FIG. 13, when the lower pad 2 incorporating the upper pad 1 is placed in the shoe 4, since the coupling member 23 of the lower pad 2 restricts the positioning member 121 of the upper pad 1 toward the X-axis (left-right direction) And the movement in the Y-axis (front-rear direction) direction. Therefore, when the user's foot portion 5 is stepped on the upper pad 1, the upper pad 1 is restricted by the coupling member 23 of the lower pad 2, so it does not advance. Moving backwards or left and right, the user can walk stably, the foot 5 does not have an uncomfortable feeling, and the foam 21 has independent closed bubbles, and has the advantages of light weight and sufficient supporting force. At the same time, it combines the characteristics of shock absorption and cushioning to reduce the force when the user presses the foot. Moreover, since the joint between the upper pad 1 and the lower pad 2 is not a dense table, and there is a gap, when the user walks, the upper pad 1 will be pressed against the lower pad 2, so that the upper pad 1 and the lower pad 2 will open and close. And the closing action, in order to drive the airflow, and quickly bring out the heat energy of the sole to achieve the purpose of heat dissipation; further, since the upper pad 1 and the lower pad 2 are detachable and combined, when the upper pad 1 uses a section When the time or dirt is generated, the user can remove the upper pad 1 from the lower pad 2 and replace the new upper pad 1 to achieve cost saving.

The advantages of the insole structure provided by this creation are compared with other conventional techniques:

1. The underlying pad of this creation is a chemical chamber with a cross-linked foam (XPE Foam or XPP Foam) or an electronic cross-linked foam (EPE Foam or EPP Foam). The foam composed of the connected independent bubbles is used as the main body, so the cushioning and shock absorption and dispersion effects are quite good, and the vibration force and pressure generated by the user when walking can be absorbed, and the weight of the foam is light and placed. When in the shoe, the weight of the whole shoe can be reduced, thereby reducing the burden on the user's foot, and the lightweight weight of the underpad can make the upper pad material have better selection and design.

2. The underlying material of this creation is a chemical cross-linked foam (XPE Foam or XPP Foam) or an electronic cross-linked foam (EPE Foam or EPP Foam) with many gas chambers. The foam composed of the connected independent bubbles has strength due to the material characteristics, and is easy to be heated and softened to be cooled into various arch shapes by the mold to fit various foot types, thereby solving the problems of the flat foot low arch and the high arch. Balance the support, and then achieve the purpose of the pelvis and the spine.

3. This creation separates the upper pad and the lower pad, and then combines them in use to omit the complicated process of forming the insole integrally, which makes the cost of the case relatively low, so as to reduce the burden on the consumer.

4. This creation divides the insole into upper and lower pads. As long as the force from the Z axis (upward force) is applied, the upper pad can be easily removed from the lower pad, allowing the user to replace the upper pad. The upper pad is cleaned, which is an effect that cannot be achieved by the conventional insole.

5. The top pad of this creation has the characteristics of deformation, as long as the under pad is molded into the shape of the human sole, When the upper pad is placed on the lower pad, it will be shaped according to the shape of the top surface of the lower pad to omit the working time of the upper pad shaping.
