Description

Vacuum shaping and heat-setting corrective insole manufacturing method

The invention relates to a method for manufacturing a corrective insole, in particular to a method for correcting an insole which can correct a foot in a correct posture after a vacuum operation and a heating operation, so as to effectively support a "foot arch" of a "flat foot" patient and avoid " The problem of the collapse of the arch of the foot continues to deteriorate, and it effectively guides the problem of the calcaneus valgus of the patient with "valgus". In addition, the use of the corrective insole can also keep the sole of the foot in the correct posture and achieve preventive health care. efficacy.

Generally speaking, the human foot is made up of 26 bones, 57 joints, and 107 ligaments. The above structure forms a "foot arch" on the bottom side of the foot. When people walk, walk, run or jump with their feet. At the time of the event, the "foot arch" can help maintain the balance and support of the body, and provide a good shock absorber cushioning capacity to alleviate the various pressures on the foot and the reaction force from the ground during the activity. Therefore, the "foot arch" is lacking. People are prone to foot acid, fatigue or falls, and even cause changes in the bearing axis, which in turn leads to problems of knee and hip wear in the future, and even affects the balance of the pelvis, spine and cervical vertebrae. Produce a variety of health issues.

According to the information, the most common "foot arches" in modern times are "Flat Foot" and "Pronated Foot". Please refer to Figure 1a for the "flat feet". Refers to the phenomenon that the "longitudinal arch" of the sole of the foot is low (as indicated by the dotted line), and the lowering of the "crossed arch" is also called "opening the foot"; also, as shown in Figure 1b, "the valgus foot" is Outside the calcaneus Turning over (as indicated by the dotted line on the left foot), the "calcaneus" valgus will cause the body's gravity line to be not evenly transmitted to the foot, thus indirectly causing the burden on the knee and spine, and often combined with the knee Joint valgus (X-leg) and lower back pain.

In the second investigation, for young children, the musculoskeletal system of children aged 1 to 6 is at a stage of rapid development and integration. However, not all children's musculoskeletal system's self-balancing mechanism can work well, if musculoskeletal. If the deviation of the system exceeds the reasonable range, the correction should be sought as soon as possible so as not to miss the golden correction period. For example, children with severe "overturned foot" and "flat feet" have an "flat foot" phenomenon due to their underdeveloped ligaments and muscles. At this time, if the "valgus" is beyond reasonable range Not only will it seriously undermine the balance of biomechanics of the lower extremities, so that every step of the child will be unsteady, and the problem will be that the body's weight will not be scattered evenly due to the weight of the body, and the body's gravity line will be shifted in the future. Under the circumstances, it is necessary to customize a "corrective shoe" or "corrective insole" according to the individual needs to effectively support the "foot arch" and prevent the "foot arch" from collapsing and continue to deteriorate. The problem of guiding the gravity line offset.

The purpose of tailor-made tailor-made "corrective shoes" or "corrective insoles" is to help children guide the development of bones and muscles as early as possible to avoid irreparable deformities in the future. After all, children's foot bones and muscles are like saplings. Like the roots, if it is tilted immediately, if it can be immediately corrected, as the years grow, the roots of the tree will naturally lead back to the correct position. However, the tailor-made tailor-made "corrective shoes" or "corrective insoles" Not only do you have to wait for a few weeks, but the cost is not too high. It takes thousands to tens of thousands of dollars, and the children in the developmental period must be replaced regularly, and they have corrective effects. Therefore, for some parents, it will undoubtedly cause economics. A heavy burden on it.

Accordingly, how to design a method for correcting the insole so that the corrective insole required by the patient can be quickly and immediately formed, so that the patient can immediately obtain a low price after ordering. Customizing a tailored insole, and the corrective insole can fully match the overall or partial configuration of the patient's foot and perform correction to effectively correct the aforementioned problems of "flat feet" and "valgus feet" Here are the important issues that you want to solve.

The invention is a vacuum shaping and heat-setting correcting insole method, please Referring to Figures 2 to 4, the orthotic insole 1 can be placed in a shoe (not shown) for the user's foot to step on. In the first embodiment, the orthotic insole 1 includes a The inner cover layer 10, a plurality of thermoplastic elastic particles 11 (such as TPU, TPEE, SEBS, etc.) and an outer cover layer 13, wherein the inner cover layer 10 is a gas permeable material (such as: Made of a breathable fabric or a breathable plasticized film, and having flexibility or elasticity itself, and the periphery of the inner cover 10 can be sealed and a first receiving space is formed therein, and the heat is further The shaped elastic particles 11 are filled into the first receiving space such that the inner covering layer 10 assumes a predetermined thickness (as shown in FIG. 2) and is maintained in a soft state, and the thermoplastic elastomer particles 11 are maintained. The particle diameter is larger than the gas permeable pore size of the inner cladding layer 10, and therefore, the thermoplastic elastomer particles 11 can move only within the inner cladding layer 10, but cannot be separated from the inner cladding layer 10, and The thermoplastic elastomer particles 11 have a melting point lower than the melting point of the inner coating layer 10, that is, when the thermoplastic elastomer particles 11 are in a molten state, The inner cover 10 still maintains its integrity without being in a molten state.

In addition, as shown in FIGS. 2 to 4, the outer covering layer 13 is made of a gas impermeable material (for example, an air impermeable plasticizing film), and has flexibility or elasticity itself, wherein the outer covering layer The periphery of the layer 13 can be sealed to form a second receiving space therein, and the inner covering layer 10 together with the thermoplastic elastomer particles 11 can be accommodated in the second receiving space, so that the outer packaging The cover layer 13 has a predetermined thickness and is also maintained in a soft state. Further, the outer cover layer 13 is provided with an air passage 131 which can communicate with the inside and the outside of the outer cover layer 13 when the outer cover layer 13 When squeezed, the air therein can be discharged to the outside of the outer covering layer 13 via the air passage 131. Further, the thermoplastic elastomer particles 11 have a melting point lower than the melting point of the outer covering layer 13. That is, when the thermoplastic elastomer particles 11 are in a molten state, the outer cladding layer 13 can maintain its integrity without being in a molten state.

Referring to FIGS. 2 and 5, in the first embodiment, the inner cladding layer 10 is filled into the outer cladding layer 13 together with the thermoplastic elastomer particles 11 (ie, the fifth layer). After the step (301) of the figure, "filling operation", the planar configuration of the inner covering layer 10 and the outer covering layer 13 is integral or partial to the sole of the foot (for example, corresponding to the phalanges, the midfoot bones or the feet). The planar configuration of the partial portion of the calcaneus is matched, so that when the entire or part of the sole is stepped on the outer covering layer 13 in the correct posture, the thermoplastic elastic particles 11 may be integral or partial with the sole of the foot. The three-dimensional configuration is displaced, and at the same time, the air in the outer cladding layer 13 and the inner cladding layer 10 is discharged to the outside of the outer cladding layer 13 via the air passage 131 due to the weight applied by the sole (ie, Step (302) of the fifth figure (step shaping operation), after which an air extracting device (not shown) is connected to the air passage 131 to pass the second receiving space via the air passage 131. And evacuating the first accommodation space (ie, step (303) "vacuum operation" in Fig. 5), at this time, as the air is discharged to the outer cladding The outer cover layer 13 is also deformed inwardly, and the inner cover layer 10 and the thermoplastic elastomer particles 11 filled therein are extruded to make the thermoplastic elastic particles 11 closely adhere to each other. Close together, until the thermoplastic elastomeric particles 11 are shaped in a state in which they are not able to continue to be displaced (as shown in Fig. 3), the air passage 131 is hermetically sealed to form an initial insole 1A.

Furthermore, as shown in Figures 3 to 5, the initial insole (1A) is placed in a heating device (not shown) to heat the initial insole 1A (i.e., Figure 5) Step (304) "heating operation"), and the heating temperature is higher than or equal to the melting point of the thermoplastic elastomer particles 11, but lower than the melting points of the inner cladding layer 10 and the outer cladding layer 13, The thermoplastic elastomer particles 11 are melted and bonded to each other (as shown in FIG. 4) to shape the corrective insole 1 so that the corrective insole 1 is not always kept correct. The three-dimensional configuration of the posture, and it will present a solid but elastic appearance. In addition, if it is used for a long time, if it is covered When the layer 13 or the inner covering layer 10 is damaged, since the thermoplastic elastic particles 11 have been bonded into one body, the corrective insole 1 can still maintain the stereo configuration in the original correct posture to effectively extend the correction. The service life of the insole 1. It is specifically claimed herein that the heat source of the heating device of the present invention can be infrared rays, hot gases, microwaves, ultrasonic waves, high frequency waves or ultraviolet rays, etc., as long as the heating device can make the surface of the thermoplastic elastomeric particles 11 or The whole is melted by high temperature and bonded together to each other, that is, the heating device of the present invention.
