Description

Insole structure

technical field

The present invention relates to an insole structure, in particular to an insole structure with a more detachable upper pad. When the upper pad is dirty, just replace the upper pad or clean the upper pad without cleaning or discarding the entire insole. .

Background technique

The main appeal of conventional functional insoles is nothing more than the support of the arch of the foot, or the design of breathable and anti-beriberi, or the combination of shock-absorbing and dissipating pressure materials to reduce the pressure on the sole of the foot. The insole is expensive, and in order to make a functional insole, the production process is usually increased, resulting in cumbersome production, and in order to achieve one of the functions, it is usually necessary to give up other functions, such as: breathable insoles, usually the support effect is Poor, therefore, conventional insoles are difficult to integrate into one. In addition, the insole for arch support is usually recommended by professional doctors to correct the arch, which makes the cost of correcting the insole more expensive. In order to correct the arch, the functions such as shock absorption, pressure dissipation and ventilation must be abandoned. There is a need for improvement.

And whether it is a functional insole or a general insole, the main structure usually includes a main foam layer, and a layer of fabric is fixed on the top surface of the main foam layer, and is removed through the surface layer. Smell, antibacterial or add power stones to avoid the smell of shoes and take into account the user's foot health.

Although the conventional insole has multiple functions, the surface cloth layer usually cannot be removed from the foam layer of the main body, because the surface cloth layer will be closely connected with the foam layer, once the surface cloth layer is damaged or dirty, The user usually can only discard the insole and replace it, or brush the entire insole, which will cause the foam layer to absorb moisture and become damp, which reduces the service life of the insole.

Furthermore, it is very cumbersome and time-consuming to manufacture the insoles of multi-layer materials in order to fix them and keep the surface flat. Especially when other functions are to be added, the structure must be improved. It will inevitably consume a lot of man-hours, resulting in an increase in costs, relatively causing consumers to spend more money to buy, resulting in an economic burden on consumers.

Therefore, it is an urgent design to design an insole that is cheap, shortens the production time, and integrates multiple functions at the same time.

Detailed ways

Other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the drawings.

Please refer to FIGS. 1 , 2 and 3 , which are the exploded and three-dimensional schematic views of the first embodiment of the insole structure of the present invention. As can be seen from the figures, it mainly includes an upper pad 1 and a lower pad 2 . The upper pad 1 is soft or flexible. Winding or flexible or deformable elastomer, fabric or foam or combination of fabric and foam or soft and breathable leather, the upper pad 1 has a top surface 11 and a bottom surface 12, the top surface 11 For a comfortable surface, it can have anti-slip, moisture absorption and perspiration wicking and deodorizing properties, and a positioning element 121 is disposed on the bottom surface 12 . In this embodiment, the positioning element 121 is a matte surface. In addition, 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 with shock absorption and pressure dissipation properties.

The bottom pad 2 includes a foam body 21 composed of independent air cells with many air cells that are not connected. The foam body 21 can be a chemical cross-linked foam body (XPE Foam or XPP Foam) or It is made of electronic cross-linked foam (EPE Foam or EPP Foam), the foaming ratio is 2-40 times, and the thickness is 2mm, 3mm, 4mmc or 5mm. The anti-slip element 22, the anti-slip element 22 can be made of synthetic rubber, the anti-slip element 22 is provided with an anti-slip pattern, and the top surface of the foam body 21 is provided with a binding element 23, in this embodiment, the binding element 23 is a mesh Fiber burr wire, the mesh fiber burr wire can be covered or partially combined on the top surface of the foam body 21, the length of the mesh fiber burr wire must be less than the thickness of the upper pad 1, to avoid the mesh fiber burr wire running through The top surface of the upper pad 1, and the mesh fiber burr wire is arranged obliquely upward or straight upward.

The foaming ratio of the above-mentioned foam 21 is preferably 2 times, 3 times, 4 times, 5 times, 6 times, 7 times, 8 times, 9 times, 10 times, 11 times, 12 times, 13 times, 14 times times, 15 times, 16 times, 17 times, 18 times, 19 times, 20 times, 21 times, 22 times, 23 times, 24 times, 25 times, 26 times, 27 times, 28 times, 29 times, 30 times, 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 combined with the top surface of the lower pad 2, so that the positioning element 121 of the upper pad 1 is tightly combined with the combining element 23 of the lower pad 2, and the upper pad 1 is fixed on the lower pad 2. In this embodiment 4 to 6, the mesh fiber burr wire penetrates into the rough surface of the upper pad 1, once the upper pad 1 receives the force in the X (left and right direction) or Y axis (front and rear direction) direction, The upper pad 1 does not slide because it is limited by the burrs of the mesh fibers. However, as shown in FIG. 6 , if the upper pad 1 is subjected to a force in the direction of the Z-axis (up and down direction), it can be easily pulled upward, so that the burr surface of the upper pad 1 is separated from the mesh fiber burr wire, and is connected with the lower pad 1. 2-phase disengagement.

Please refer to FIG. 7 and FIG. 8 , the lower pad 2 can first be shaped into the shape of the sole of the foot (corresponding to the bulge of the arch of the foot). When the lower pad 2 is placed on, the upper pad 1 will be shaped into the same shape as the top surface of the lower pad 2 as shown in FIG. 8 (the shape with the arch of the foot).

Please refer to FIGS. 9 , 10 and 11 , the positioning element 121 on the bottom surface of the upper pad 1 and the bonding element 23 on the top surface of the lower pad 2 can be mutually felt devil felts. As shown in FIG. 9 , the positioning element 121 And the combination element 23 can be arranged on both sides of the upper pad 1 and the lower pad 2; or as shown in FIG. or as shown in FIG. 11 , the positioning element 121 and the combining element 23 can be arranged near the front and rear ends of the upper pad 1 and the lower pad 2 , and other structures are the same as those in FIGS. 1 to 8 . I won't go into details here.

Please refer 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 combined, there is a gap between the upper pad 1 and the lower pad 2, and the gap can supply the airflow 3 to circulate, so as to achieve cooling purpose.

Please refer to FIG. 13 , when the lower pad 2 combined with the upper pad 1 is placed in the shoe 4 , the positioning element 121 of the upper pad 1 will be restricted by the combination element 23 of the lower pad 2 toward the X-axis (left and right directions) and The movement in the Y-axis (front-rear direction) direction, therefore, when the user's foot 5 steps on the upper pad 1 to walk, the upper pad 1 is restricted by the coupling element 23 of the lower pad 2, so it will not move forward, It can be moved backward or left or right, so that the user can walk stably without uncomfortable feeling on the feet 5, and the foam body 21 has independent closed air bubbles, which has the advantages of light weight and sufficient supporting force. At the same time, it has the characteristics of shock absorption, pressure dissipation and cushioning, so as to reduce the force when the user's feet press down. In addition, since the junction of the upper pad 1 and the lower pad 2 is not tight, but 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 be opened and closed. And the closing action to drive the airflow, and quickly bring out the heat energy of the sole of the foot to achieve the purpose of heat dissipation; Furthermore, since the upper pad 1 and the lower pad 2 are detachable combination, when the upper pad 1 is used for a period of time When time, dirt or odor occurs, the user can remove the upper pad 1 from the lower pad 2 and replace the upper pad 1 with a new one, so as to achieve the purpose of saving costs.

After the present invention separates the upper pad and the lower pad, they are combined in use to omit the cumbersome process of integrally processing and molding the conventional insole, resulting in a relatively low cost in this case, to reduce the burden on consumers, and the lower pad. It is very sturdy and does not accidentally damage, so that the upper pad can be replaced at any time, allowing consumers to choose the upper and lower pads of different thicknesses or materials or different functions to combine, which will contribute more to the selectivity and economy of consumers.

4. The present invention divides the insole into an upper pad and a lower pad. 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, and more Wash the upper pad, which is an effect that cannot be achieved by conventional insoles.

5. The upper pad of the present invention has the characteristic of deformation. As long as the lower pad is molded into the shape of the sole of the human body, 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, so as to omit the upper pad.
