Description

Technical Field

[0001] The present invention relates to an insole with anti-slip and elastic support for the arch, and in particular, the insole is provided with a forefoot cushion, an arch cushion, and a heel cushion to improve the comfort of the user's walking and the anti-slip effect.

Background Art

[0002] A general shoe is composed of an outsole, a midsole, and an upper. Among them, the outsole is at the bottom of the shoe, which is the part that directly touches the ground, and mainly has the functions of wear resistance and anti-slip. The upper is at the top of the shoe, mainly has breathability, and covers the back of the human foot in a stable state. The midsole is located between the outsole and the upper and is fixed to the upper surface of the outsole, so it provides elastic cushioning between the human foot and the outsole. When the user walks, the midsole and outsole of the shoe can absorb, buffer, and disperse the impact force generated when the foot lands when the user walks, achieving the effect of protecting the foot.

[0003] There is an insole layer on the upper pad of the midsole, which allows the user to wear comfortably. However, the insole is generally flat and different from the natural curve of the human foot by the arch of the foot. Therefore, there are various arch insoles that mimic the shape of the sole of the foot, which are made into a monolithic and undulating curved shape of the whole foot. A pad is provided on the upper surface of the midsole, and the user can reduce the pressure on the arch when wearing.

Summary of the Invention

Problems to be Solved by the Invention

[0004] A well-known full-sole arch insole includes the forefoot, arch, and heel from front to back. By strengthening the support at the arch of the foot, when walking, the user's forefoot, arch, and heel can be closely attached to the arch insole. It is known that it can maintain the normal height of the user's arch, disperse the pressure on the foot, achieve shock absorption, reduce the force on the joints and spine of the lower limbs, and achieve healthy foot functions.

[0005] Another commercially available arch insole is the half-foot insole. Since the front edge does not extend to the toe part of the shoe, when the pad is in the midsole, the upper surface of the midsole in the shoe is slippery. Especially when the user walks, the half-foot insole is slippery at the midsole, and it is also easy to slip between the sole of the human foot and the insole, and it cannot cope with the support problem.

[0006] The inventor of the present invention improved the above-mentioned drawbacks and invented an arch insole published under Taiwan Utility Model Publication No. M651432. Its feature is that a plurality of anti-slip cushions are secondarily injection-molded on the insole to achieve the effects of anti-slip and support. After actual use, it improves the lack of the conventional arch insole and improves the comfort of the user's walking. However, the inventor further improved the invention of the above-mentioned Taiwan Utility Model Publication No. M651432, and the stretchable support function of the foot arch insole became more perfect.

Means for Solving the Problems

[0007] The object of the present invention is to provide an insole with an anti-slip and elastic support function for the arch on the sole of the foot. Forefoot cushions, arch cushions, and heel cushions are respectively provided on the insole corresponding to the positions of the human forefoot, arch, or heel. Furthermore, the arch cushion has an upward elastic support effect, achieving the functions of anti-slip, buffering, and elastic support for the human arch, improving the comfort of the user's walking, and reducing the pressure on the foot.

[0008] To achieve the above object, the present invention is a kind of insole with anti-slip on the sole and elastic support for the arch. The insole has a plate-shaped main body corresponding to the shape of the human foot. The main body has a forefoot part, an arch support part, and a heel part corresponding to the shape of the human sole. The upper surface of the arch support part is curved upward, The main body is provided with a first positioning opening at a position corresponding to the forefoot part. The second positioning opening is arranged at a position corresponding to the arch support part area, and the third positioning opening is arranged at a position corresponding to the heel part area. Since the first positioning opening is fixed with a forefoot cushion around its inner circumference, the second positioning opening is fixed with an arch cushion around its inner circumference, and the third positioning opening is fixed with a heel cushion around its inner circumference. When the main body cushion is in the midsole of the shoe, the upper surfaces of the forefoot cushion and the heel cushion are in contact with the sole of the human foot respectively, having an anti-slip effect. Since the bottom surfaces of the forefoot cushion and the heel cushion are in contact with the midsole of the shoe respectively, they have anti-slip and buffering properties. The arch cushion has an upward elastic support effect on the part in contact with the human arch.

[0009] With the above structure, the insole is provided with a forefoot cushion, an arch cushion, and a heel cushion respectively at the positions of the human forefoot, arch, and heel. Also, the arch cushion has an upward elastic support effect on the part in contact with the human arch, achieving the functions of anti-slip, buffering, and elastic support, relieving the foot pressure of the user when standing or walking, and improving the comfort of the user during walking.

[0010] Hereinafter, the embodiments of each component will be further described.

[0011] In an embodiment, the forefoot cushion, the arch cushion, and the heel cushion are each filled in the form of secondary injection molding or fixed in the form of assembly in the corresponding first, second, and third positioning openings.

[0012] In an embodiment, the main body, the forefoot cushion, the arch cushion, and the heel cushion are each made of a plastic, silicon, or rubber material with different hardnesses, and the upper surfaces of the forefoot cushion, the arch cushion, and the heel cushion protrude from the upper surface of the main body, respectively.

[0013] In an embodiment, the upper surfaces of the forefoot cushion and the arch cushion are arc convex surfaces.

[0014] In an embodiment, since the contour of the first positioning opening is generally in the shape of a long arc extending horizontally, the forefoot cushion fixed to the first positioning opening is supported corresponding to the forefoot of the human body, providing an anti-slip and buffering effect between the forefoot of the human and the midsole of the shoe.

[0015] In an embodiment, since the bottom surface of the arch support area of the main body has an arch-shaped concave arc with respect to the forefoot and heel areas, when the main body corresponding to the arch support area is pushed down, it will have an upward elastic reaction force.

[0016] In an embodiment, the second positioning opening is composed of a front arc edge near the forefoot and a rear arc edge near the heel area. The curvature of the front arc edge is larger than the curvature of the rear arc edge, and both ends of the front arc edge and the rear arc edge are connected to each other. Therefore, the arch cushion fixed to the second positioning opening supports corresponding to the arch part of the human body, providing an upward elastic support and shock absorption effect for the arch of the human.

[0017] In an embodiment, the third positioning opening is composed of a straight edge near the arch support part and a U-shaped edge near the rear edge of the main body. The U-shaped edge is connected to each other at both ends of the straight edge. Therefore, the heel cushion fixed to the third positioning opening is supported corresponding to the heel part of the human foot, providing an anti-slip and buffering effect between the heel of the human foot and the midsole of the shoe.

[0018] In an embodiment, a magnet capable of contacting the sole of a human foot between the arch cushion and the heel cushion is provided on the upper surface of the main body.

[0019] In an embodiment, both sides of the main body and the periphery of the heel area extend outward with a limiting edge portion that gradually rises, and a plurality of reinforcing ribs capable of enhancing the structural strength are provided on the bottom surface of the limiting edge portion.

[0020] Compared with the prior art, the positions of the insole for the forefoot, arch, and heel of a human are respectively provided with a forefoot cushion, an arch cushion, and a heel cushion. Furthermore, the arch cushion and the upper concave arc generate a shock-absorbing and elastic supporting effect on the arch of the user's foot, achieving the functions of anti-slip, buffering, and elastic support, reducing the pressure on the user's foot when standing or walking, and improving the comfort of the user's walking.

[0021] The following will describe embodiments suitable for the invention in conjunction with the drawings based on the technical means of the present invention.

Modes for Carrying Out the Invention

[0024] The following will more fully describe various embodiments with reference to the diagrams, in which several exemplary embodiments are shown. However, the concept of this utility model can be embodied in many different forms and should not be construed as limited to the exemplary embodiments described herein. Specifically, the provision of such exemplary embodiments makes the present invention more detailed and complete, and the scope of the concept of the present invention can be fully conveyed to those skilled in the art. Similar numerical values always indicate similar components.

[0025] As shown in FIGS. 1 to 4, the present invention is a kind of insole having an elastic support for the sole and the instep of the foot. The insole has a plate-shaped main body 100 that is substantially similar in shape to the part of the human foot excluding the toes. That is, taking the half-foot sole type arch insole as an example, the main body 100 corresponds to the shape of the human foot and has a forefoot part 10, an arch support part 20, and a heel part 30. The upper surface of this arch support part 20 forms an upwardly curved arc, and the lower side of the arch support part 20 of the main body 100 has an upper concave arc 201 that is all arched and concave with respect to the forefoot part 10 and the heel part 30. During implementation, the shape of the main body 100 does not exclude adaptation to the specifications of a full-foot type arch insole, and it only needs to extend the front edge of the forefoot part 10 to the part relative to the toes.

[0026] The main body 100 is provided with a first positioning opening 11 at the position corresponding to the forefoot part 10, a second positioning opening 21 at the position corresponding to the arch support part 20, and a third positioning opening 31 at the position corresponding to the heel part 30. The first positioning opening 11 is fixed by a forefoot cushion 12 around its inner circumference, the second positioning opening 21 is fixed by an arch cushion 22, and the third positioning opening 31 is fixed by a heel cushion 32 around its inner circumference.

[0027] The insole has a pad placed on the upper surface of the midsole of the shoe. When the user steps on and presses down the main body 100 with the sole of the foot, the user's arch is pressed against the arch support part 20. Through the upper concave arc 201 and the arch cushion 22, the arch support part 20 generates shock absorption and upward elastic support for the user's arch (Arch of the foot).

[0028] At the same time, the front part of the user's foot is pressed against the front part cushion 12 and also pressed against the heel cushion 32. As a result, the sole of the human body comes into contact with the upper surfaces of the front part cushion 12 and the heel cushion 32 respectively, providing an anti-slip function. Since the front part cushion 12 and the heel cushion 32 are simultaneously pressed down by the weight of the human body, the bottom surfaces of the front part cushion 12 and the heel cushion 32 are in close contact with the upper surface of the midsole of the shoe respectively. Through the anti-slip and buffering effects between the front foot and the heel of the human and the front part cushion 12, the heel cushion 32 and the midsole of the shoe, the sole of the human body and the shoe are combined as a whole, effectively improving the wearing comfort of the shoe and preventing the midsole of the shoe from slipping on the sole of the human foot during walking.

[0029] During implementation, the bottom surface of the main body 100 in contact with the midsole of the shoe can be further arranged with an anti-slip line (not shown in the figure). Transverse anti-slip ribs 321 are respectively provided on the bottom surfaces of the front part cushion 12 and / or the heel cushion 32. The anti-slip ribs 321 have an anti-slip effect between the auxiliary insole and the midsole of the shoe.

[0030] During implementation, the bottom surface of the main body 100 in contact with the midsole of the shoe can be further arranged with an anti-slip line (not shown in the figure). Transverse anti-slip ribs 321 are respectively provided on the bottom surfaces of the front part cushion 12 and / or the heel cushion 32. The anti-slip ribs 321 have an anti-slip effect between the auxiliary insole and the midsole of the shoe.

[0031] In each positioning opening, in the embodiment, the first positioning opening 11 conforms to the shape of the human forefoot, is disposed at a position corresponding to the human forefoot, and its contour is an arc with a long horizontal extension. The forefoot cushion 12 fixed to the first positioning opening 11 supports the human forefoot position. As a result, through the forefoot cushion 12, a non-slip and buffering effect is provided between the human forefoot and the midsole of the shoe.

[0032] In the embodiment, the second positioning opening 21 is composed of a front arc edge 211 close to the forefoot part 10 and a rear arc edge 212 close to the heel part 30. The radian of the front arc edge 211 is larger than that of the rear arc edge 212. Both ends of the front arc edge 211 and the rear arc edge 212 are connected to each other to form an oval contour. The arch cushion 22 fixed to the second positioning opening 21 is correspondingly supported at the human foot arch part. Also, due to the design of the upper concave arc part 201 on the bottom surface of the foot arch support part 20 of the main body 100, the arch cushion 22 can provide an upward elastic support and shock absorption effect for the human arch.

[0033] In the embodiment, the third positioning opening 31 is disposed at a position corresponding to the heel of the human foot according to the shape of the human heel, and is close to the arch support part 20 Straight edge 311 and close to the rear edge of the main body 100 U-shaped edge It is composed of 312, and U-shaped edge 312 and Straight edge Both ends of 311 are connected to each other. The heel Part cushion 32 fixed to the third positioning opening 31 is supported correspondingly at the heel part of the human foot. As a result, a non-slip and buffering effect between the heel of the human foot and the midsole of the shoe is provided through the heel cushion 32.

[0034] In manufacturing, the forefoot cushion 12, the arch cushion 22, and the heel PartThe cushion 32 can be filled and fixed in the corresponding first, second, and third positioning openings 11, 21, 31 respectively in the form of secondary injection molding. Also, in order to strengthen the stability between each cushion and each positioning opening, two annular grooves and convex rings that are embedded and positioned with each other are arranged therebetween to prevent each cushion from falling off from the corresponding positioning opening. Of course, the forefoot cushion 12, the arch cushion 22 and the heel Part The cushion 32 is not excluded from being manufactured separately, and then it is assembled, fitted, and fixed in the first, second, and third positioning openings 11, 21, 31 respectively.

[0035] Furthermore, the forefoot cushion 12, the arch cushion 22 and the heel Part The upper surfaces of the cushions 32 each protrude from the upper surface of the main body 100. Since the upper surfaces of the forefoot cushion 12 and the arch cushion 22 are arc convex surfaces, the thicknesses of the forefoot cushion 12 and the arch cushion 22 will be slightly larger than the thickness of the main body 100, and the effect of the user stepping on the cushion can be increased.

[0036] Also, on the upper surface of the main body 100, between the arch cushion 22 and the heel Part A magnet 40 is provided between the cushion 32. By the user's sole contacting the magnet 40, the function of promoting blood circulation in the sole can be achieved.

[0037] In order for the material hardness of the main body 100 to support the weight of the human body without collapsing the upper concave arc 201, the material elasticity of the forefoot cushion 12, the arch cushion 22, and the heel cushion 32 is made to be able to provide a buffering and anti-slip function. Therefore, the main body 100, the forefoot cushion 12, the arch cushion 22 and the heel Part The cushion 32 can be made of materials with different softnesses during implementation. For example, the material of the main body 100 is a plastic having a certain hardness and elasticity.

[0038] Also, in the embodiment, both sides of the main body 100 and the peripheral part of the heel region 30 extend outward and gradually rise. Restricted edge There is a 101, which is used to fit to the peripheral part of the relative position of the user's sole. Restricted edge To strengthen the strength of 101, Restricted edge A plurality of reinforcing ribs 60 are arranged on the bottom surface of 101, Restricted edge so that its structural strength can be strengthened and 101 is less likely to deform.

[0039] Subsequently, the forefoot cushion 12, the arch cushion 22, and the heel Part cushion 32 are made of relatively soft silicon, rubber, latex, and other materials with anti-slip and cushioning elastic effects. Considering the breathability of the insole, the main body 100 is provided with a plurality of ventilation holes 50 at positions other than the first, second, and third positioning openings 11, 21, 31, so as to enhance the breathability for the user to wear through the ventilation holes 50.

[0040] In summary, the present invention can actually achieve the desired functions and purposes, and those skilled in the art can implement it based on the above detailed description. Therefore, from the above embodiments, changes in equivalent structures still do not deviate from the scope of the rights of the present invention. That is, changes or modifications made in the same creative spirit related to the present invention should be included in the protection scope of the present invention.
