Description

Composite Insole (Part 1)

This invention is a composite insole comprising a set of arch support insoles and full-foot insoles that can be joined and positioned together to prevent the arch support insoles from slipping inside the shoe.

The arch of the foot can support the body weight and absorb the impact from the ground when walking, reducing the stress on the lower limb joints and spine. Therefore, there are many types of arch support insoles on the market for users to place on the bottom of their shoes to reduce pressure on the arch and achieve health benefits.

The creator has made improvements to arch support insoles, including M651432, M669027 and M674636. After implementation, these arch support insoles do increase walking comfort and stability and reduce foot pressure.

The arch support insoles of these known technologies are semi-foot-shaped and have anti-slip treads on the bottom surface of the forefoot and heel areas. When the user walks, the weight of the body presses down, causing the bottom surface of the forefoot and heel areas to fit tightly against the top surface of the insole in the midsole, thereby enhancing the anti-slip effect.

However, when the user lifts their other foot, the arch support insole loses the pressure of the body weight. Additionally, some users have a large gap between their shoes and feet, allowing the foot to easily slide inside the shoe. This causes the arch support insole, despite its anti-slip treads, to still be pushed forward by the foot, resulting in slippage. Therefore, how to improve this shortcoming of the arch support insole being pushed forward by the user's foot is the problem that the creator aims to address.

The purpose of this invention is to provide a composite insole comprising a set of arch support insoles and full-foot insoles that can be coupled and positioned together, so that the arch support insole can be prevented from slipping inside the shoe when the user wears the shoe and is insulated with it.

To achieve the above objectives, this invention is a composite insole comprising a full-length insole and an arch support insole superimposed on the full-length insole. The arch support insole has a plate-like body that corresponds to the shape of the human foot, comprising a forefoot area, a heel area, and an arch support area located between the forefoot area and the heel area. Its features include... The arch support insole has at least one downwardly protruding buckle on the bottom surface of the forefoot area and/or heel area. The top surface of the full-length insole has a recessed hole opposite to the buckle, and the buckle of the arch support insole can be inserted into the recessed hole of the full-length insole, so that the arch support insole is attached and positioned on the top surface of the full-length insole, preventing the arch support insole from sliding inside the shoe.

The implementation methods of each component are further explained below:

In practice, the buckle of the arch support insole is a hollow short column or hollow ball made of plastic to provide cushioning elasticity when the arch support insole is compressed.

In practice, the bottom surface of the forefoot area and/or heel area of the arch support insole is provided with at least one upper recessed hole. The depth of the upper recessed hole is less than the height of the buckle, so that the top of the buckle can be separately inserted into the upper recessed hole of the arch support insole, and the bottom of the buckle can be separately inserted into the lower recessed hole of the full-foot insole.

In practice, the buckle is joined to the bottom surface of the forefoot area and/or heel area of the arch support insole by a secondary molding process.

In practice, the arch support insole body has a slot in the forefoot area, and a forefoot support pad is provided inside the slot. The buckle is located on the bottom surface of the forefoot support pad.

In practice, the forefoot support pad and the arch support pad are made of plastic, silicone or rubber materials of different hardness.

In practice, a slot is provided in the heel area of the arch support insole body, and a heel support pad is provided inside the slot. The buckle is provided on the bottom surface of the heel support pad.

In practice, the heel support pad and the arch support pad are made of plastic, silicone or rubber materials of different hardness.

In practice, the bottom surface of the arch support area of the arch insole body arches upward relative to the forefoot and heel areas, so that the arch insole body has an upward elastic reaction force when it is pressed down relative to the arch support area.

In practice, the arch support area of the insole body is provided with a slot, and an arch support pad is provided inside the slot. The arch support pad and the body are made of plastic, silicone or rubber materials with different hardness.

Compared to previous technologies, this invention combines the arch support insole with a buckle and a recessed hole on the top surface of the full-length insole, and then extends from the front edge of the full-length insole to the toe and is positioned inside the shoe. This prevents the arch support insole from being pushed or displaced by the user's foot inside the shoe when the user wears the shoe and is wearing it.

Based on the technical means of this invention, the following are examples of implementation methods suitable for this invention, along with accompanying illustrations:

As shown in Figures 1 to 3, this invention is a composite insole comprising a full-foot insole 1 and an arch support insole 2 superimposed on the full-foot insole 1. The arch support insole 2 has a plate-shaped body 10, which is substantially the same as the outer contour of the human foot and has a forefoot area 11, a heel area 12, and an arch support area 13 located between the forefoot area 11 and the heel area 12. The bottom surface of the arch support area 13 arches upward relative to the forefoot area 11 and the heel area 12, so that the arch support insole 2 body 10 has an upward elastic reaction force when it is pressed down relative to the arch support area 13.

The forefoot area 11 and/or heel area 12 of the arch support insole 2 are provided with at least one downward protruding buckle 20 on the bottom surface, and the top surface of the full-foot insole 1 is provided with a recess 21 at the position opposite to the buckle 20.

As shown in Figure 4, the buckle 20 of the arch support insole 2 can be inserted into the recessed hole 21 of the full-length insole 1, so that the arch support insole 2 is combined and positioned on the top surface of the full-length insole 1. The full-length insole 1 is usually made of elastic foam material. When the user wears the shoe and steps on the arch support insole 2, the foot applies downward pressure, causing the bottom surface of the arch support insole 2 to tightly overlap with the top surface of the full-length insole 1, thereby strengthening the positioning of the buckle 20. The front edge of the full-length insole 1 extends to the toe and is positioned inside the shoe, preventing the arch support insole 2 from being pushed and displaced by the user's foot inside the shoe, so that the arch support insole 2 can support the user's arch in the correct position.

In practice, the buckle 20 of the arch insole 2 is a hollow short column or hollow ball made of plastic, which can be slightly deformed and embedded in the recessed hole 21, and provides cushioning elasticity when the arch insole 2 is pressed down, so as to avoid the user from feeling foreign objects when stepping on it and maintain the comfort of the arch insole 2.

The arch support insole 2 and the buckle 20 can be combined in various ways. For example, as shown in Figures 1 to 4, the bottom surface of the forefoot area 11 and/or heel area 12 of the arch support insole 2 is provided with at least one upper recess 22. The depth of the upper recess 22 is less than the height of the buckle 20, so that the top of the buckle 20 can be inserted into the upper recess 22 of the arch support insole 2, and the bottom of the buckle 20 can be inserted into the lower recess 21 of the full-foot insole 1, so that the arch support insole 2 is positioned on the top surface of the full-foot insole 1.

Alternatively, as shown in Figure 5, the buckle 20 is integrally formed and joined to the bottom surface of the forefoot area 11 and/or heel area 12 of the arch support insole 2 by a secondary injection process. The bottom of the buckle 20 is then embedded in the recessed hole 21 of the full-foot insole 1, so that the arch support insole 2 is assembled and positioned on the top surface of the full-foot insole 1.

As shown in Figures 6 to 9, the arch support insole 2 can further improve the comfort of stepping. A slot 14 is hollowed out in the forefoot area 11, heel area 12 and arch support area 13 of the body 10. The inner perimeter of each slot 14 is provided with a forefoot support pad 30, a heel support pad 40 and an arch support pad 50 respectively by combination or secondary injection molding.

The forefoot support pad 30, heel support pad 40, and arch support pad 50 can contact the human foot, providing soft and comfortable elastic cushioning. Each support pad and the body 10 of the arch insole 2 are made of plastic, silicone, or rubber materials of different hardness to increase the support of the body 10 relative to the human arch.

In this embodiment, the buckle 20 is disposed on the bottom surface of the forefoot support pad 30 and/or the heel support pad 40. Specifically, as shown in Figures 6 to 8, the bottom surface of the forefoot support pad 30 and/or the heel support pad 40 is provided with at least one upper recessed hole 22 for the top of the buckle 20 to be inserted and positioned, or as shown in Figure 9, the buckle 20 is integrally formed and combined with the bottom surface of the forefoot support pad 30 and/or the heel support pad 40; the bottom of the buckle 20 is then inserted into the lower recessed hole 21 of the full-foot insole 1, so that the arch support insole 2 with multiple support pads is combined and positioned on the top surface of the full-foot insole 1.
