Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, specifically to a hollow-cushioned shoe sole. Background Technology

[0002] A vacuum-cushioned sole has an air-filled cavity between the upper and lower parts of the sole to form an air cushion. The main difference between vacuum-cushioned shoes and ordinary soles is the air-filled cavity, which can provide a great deal of cushioning to improve the comfort of the user's feet.

[0003] However, current vacuum-cushioned shoe soles are relatively soft. While the comfort and anti-slip capabilities of vacuum-cushioned shoe soles have been improved as research and development have progressed to better handle different conditions, their pressure resistance during climbing and outdoor training still has certain shortcomings. During climbing and outdoor training, the sharp points of sharp objects in the environment can easily puncture the sole when stepped on, which can pose a safety hazard to the user's feet in severe cases.

[0004] In view of this, a medium-air cushion sole was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] An air-cushioned insole includes a bottom insole and a top insole disposed on the bottom insole. The bottom insole includes a thickened and wear-resistant outsole, the top of which is provided with a pre-installed mold cavity. The bottom of the pre-installed mold cavity is provided with a plurality of evenly distributed puncture-resistant pads, and the top of the plurality of puncture-resistant pads is provided with a rebound pressure plate and a wear-resistant pad disposed on the top of the rebound pressure plate. The top insole includes an air cushion cover disposed on the top of the pre-installed mold cavity and a thickened top pad disposed on the top of the air cushion cover.

[0008] In a preferred embodiment, the present invention can be further configured such that: the top layer of the insole also includes a plurality of uniformly distributed air cushion filling layers, and the air cushion filling layers are generally arc-shaped;

[0012] In a preferred embodiment, the present invention can be further configured such that: the bottom of the thickened sole is provided with uniformly distributed anti-slip grooves, and the inner side of the anti-slip grooves is filled with raised particles;

[0013] The thickened sole is made of thickened rubber material, and the interior of the thickened sole is filled with fascia.

[0014] In a preferred embodiment, the present invention can be further configured such that the puncture-resistant pad is made of ultra-thin stainless steel sheet by stamping, and multiple puncture-resistant pads are coated with adhesive.

[0015] In a preferred embodiment, the present invention can be further configured such that: the bottom of the rebound plate is provided with uniformly distributed correction grooves, and the top of the rebound plate is provided with uniformly distributed buffer grooves.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a mid-air cushioned shoe sole. Example 1

[0029] Combination Figures 1-4 As shown, the present invention provides a hollow air cushion sole, including a bottom insole 100 and a top insole 200 disposed on the bottom insole 100. The bottom insole 100 is used to improve the anti-slip force when landing and to prevent sharp objects from puncturing it. The top insole 200 is used to facilitate the placement of the insole and to provide greater comfort for the user's feet.

[0030] The insole bottom layer 100 includes a thickened and wear-resistant thickened sole 110. The top of the thickened sole 110 is provided with a pre-installed mold cavity 130. The bottom of the inner cavity of the pre-installed mold cavity 130 is provided with a plurality of evenly distributed anti-puncture pads 140. The top of the plurality of anti-puncture pads 140 is provided with a rebound pressure plate 150 and a wear-resistant pad 180 provided on top of the rebound pressure plate 150.

[0031] The top layer 200 of the insole includes a plurality of evenly distributed air cushion filling layers 240, an air cushion cover 210 disposed on the top of the pre-installed mold cavity 130, and a thickened top pad 220 disposed on the top of the air cushion cover 210. The air cushion filling layer 240 has an overall arc-shaped structure.

[0032] The air cushion filling layer 240 is made of thickened thermoplastic polyurethane material.

[0033] Traditional vacuum-cushioned shoe soles have certain drawbacks in actual use. In order to improve comfort and cushioning, these soles are more flexible, but their puncture resistance is also worse in climbing and outdoor training activities. In severe cases, they may be punctured or broken by sharp objects.

[0034] The sole is constructed by adding multiple evenly distributed anti-puncture pads 140 between the vacuum layer and the sole. The pre-installed mold cavity 130 stably loads the multiple evenly distributed anti-puncture pads 140 and fixes them with adhesive. At the same time, the wear-resistant pad 180 and the rebound pressure plate 150 are assembled on top of the multiple anti-puncture pads 140 with adhesive. When the thickened sole 110 is pressed and stepped on a sharp object, the multiple evenly distributed anti-puncture pads 140 can block the sharp point of the object and provide protection for the user's feet.

[0035] When the sole is in use for climbing, the multiple anti-puncture pads 140 can bend to a certain extent. At the same time, with the assistance of the rebound pressure plate 150, the multiple anti-puncture pads 140 after bending are quickly restored to their original position, thereby reducing the fatigue of the user's feet when climbing. It also provides anti-breakage protection for the thickened sole 110, air cushion cover 210 and thickened top pad 220. Example 2

[0036] Combination Figures 2-4 As shown, based on Embodiment 1, the bottom of the thickened sole 110 is provided with uniformly distributed anti-slip grooves 120, and the inner side of the anti-slip grooves 120 is filled with raised particles.

[0037] Preferably, by adding raised particles to the inner side of the anti-slip groove 120, when the sole is pressed and walked on a wet ground, the raised particles can improve the adhesion of the pressure-strengthened sole 110 to the ground, thereby improving the safety of the user walking on wet ground.

[0038] The thickened sole 110 is made of thickened rubber material, and the interior of the thickened sole 110 is filled with fascia.

[0039] Preferably, the thickened sole 110 is laminated with rubber liquid and fascia through a mold. When the thickened sole 110 is deformed under pressure to a certain extent, the fascia can provide anti-wrinkle protection for the body of the thickened sole 110, thereby improving the fatigue resistance of the thickened sole 110.

[0040] The puncture-resistant pad 140 is made of ultra-thin stainless steel sheet by stamping, and multiple puncture-resistant pads 140 are coated with adhesive.

[0041] Preferably, adhesive is injected into the top and gaps of the multiple anti-puncture pads 140. After the adhesive cures, the multiple anti-puncture pads 140, after being repeatedly bent and reset, can provide anti-puncture protection against sharp objects, while also preventing the anti-puncture pads 140 from becoming misaligned, thus affecting the user's foot comfort.

[0042] The bottom of the spring plate 150 is provided with evenly distributed correction grooves 160, and the top of the spring plate 150 is provided with evenly distributed buffer grooves 170.

[0043] The wear-resistant pad 180 has a pre-made silicone layer.

[0044] Preferably, by setting the rebound plate 150 as a corrugated structure, as the body of the thickened sole 110 bends, the rebound plate 150 in the corrugated structure can assist the user's foot to make the thickened sole 110 quickly return to its original position, so as to avoid the air cushion cover 210 bending too much and wrinkling, which would lead to the air cushion cover 210 being damaged and causing air leakage.

[0045] The rebound pad 150 can further prevent punctures by sharp objects. Example 3

[0046] Combination Figure 2 As shown, in the above embodiment, the thickened top pad 220 is made of ethylene-vinyl acetate copolymer, and the interior of the thickened top pad 220 is filled with metal wires.

[0047] The top of the thickened top pad 220 is provided with a molded groove 230.

[0048] Preferably, by incorporating laminated metal wires inside the thickened top pad 220, the thickened top pad 220 can provide anti-breakage protection for the sole during actual use and improve its compressive protection against wear of the multiple air cushion filling layers 240, thereby increasing the service life of the sole.

[0049] The working principle and usage process of this utility model are as follows: First, the pressure-resistant metal is cut into multiple anti-puncture gaskets 140 that are adapted to the structure of the pre-installed mold cavity 130. Then, the multiple anti-puncture gaskets 140 in sheet structure are evenly distributed and filled at the bottom of the inner cavity of the pre-installed mold cavity 130. Then, glue is injected onto the top of the multiple evenly distributed anti-puncture gaskets 140. Next, the pre-stamped spring pressure plate 150 is placed on top of the multiple anti-puncture gaskets 140. Then, the wear-resistant pad 180 is placed on top of the spring pressure plate 150. The side of the wear-resistant pad 180 is injected and sealed with glue to the inner wall of the pre-installed mold cavity 130.

[0050] Next, the air cushion cover 210 and the thickened top pad 220 are pressed out using a stamping die, and the multiple cut air cushion filling layers 240 are filled into the inner cavity of the air cushion cover 210. Finally, the bottom layer 100 and the top layer 200 of the insole are further molded and prefabricated using a die.

[0051] When the sole of the shoe is used for climbing and stepping on sharp gravel or foreign objects, even if the sharp gravel or foreign objects pierce the thickened sole 110, they will eventually be blocked by the evenly distributed anti-puncture pads 140.

[0052] When the sole adapts to the user's foot and climbs on the rock face, there are certain gaps between the evenly distributed multiple puncture-resistant pads 140, and under the pressure of the rebound plate 150, it maintains a sufficiently elastic deformation state. As the user's foot returns from a bent position to a normal position, the highly elastic rebound plate 150 can cause the thickened sole 110 and multiple puncture-resistant pads 140 to quickly return to their original position, thereby improving the user's wearing comfort. At the same time, the vacuum cavity formed between the abrasion-resistant pad 180, multiple air cushion filling layers 240 and air cushion cover 210 can also reduce the impact force and reduce the problem of the air cushion cover 210 being creased or broken due to excessive pressure.
