Description

Technical Field

[0001] The invention provides a sole structure and a shoe tool structure, in particular a sole structure and a shoe tool structure suitable for medium and long distance walking. Background Art

[0002] Shoes are daily necessities for human beings. The soles of shoes are basically composed of outsoles, midsoles and insoles. According to different needs, the structures of the soles are also different. The outsoles, midsoles and insoles must be produced with different molds to meet the needs of different usage occasions and environments. As a result, the current production cost of soles is high and the production efficiency is poor.

[0003] Most outsoles on the market are made of rubber to provide anti-slip function, while the midsoles are mostly made of ethylene vinyl acetate (EVA), which can provide sufficient cushioning capacity. However, traditional midsoles must be manufactured using molds of different shapes and hot-pressed foaming, which has a complex process and poor production efficiency. In addition, as road running activities become increasingly popular, there are also requirements for the comfort and protection of shoes used in medium and long-distance distances.

[0004] In order to meet the above needs, midsoles made of carbon fiber have appeared on the market. They are widely loved by consumers because of their lightness and excellent sprinting assistance for runners. However, midsoles made of carbon fiber are lightweight, and when used in medium and long-distance sports, they will increase the pressure on the ankles or joints, and may also increase the risk of injury.

[0005] In view of this, how to provide a sole with good elasticity and strength and can protect the ankle while reducing production costs is still an industry requirement with commercial value in the market. Utility Model Content

[0040] The following will discuss various embodiments of the present invention in more detail. However, this embodiment can be an application of various new concepts and can be specifically implemented in various specific scopes. The specific embodiments are for illustrative purposes only and are not limited to the scope of the disclosure. In addition, in order to simplify the drawings, some conventional structures and components will be depicted in the drawings in a simple schematic manner, and repeated components may be represented by the same number.

[0041] Please refer to Figures 1 to 4 , Figure 1 A schematic diagram of a sole structure 100 according to an embodiment of the present invention is shown. Figure 2 Draw Figure 1 An exploded perspective view of the sole structure 100 , Figure 3A Draw Figure 1 An exploded perspective view of the first plate 110, Figure 3B Draw Figure 1 An exploded perspective view of the second plate 120, Figure 4 Draw Figure 1 The sole structure 100 includes a first plate 110, a second plate 120 and a second pad 130.

[0042] The first plate 110 has a first surface 111 and a second surface 112, and the first plate 110 includes two first side pieces 113 and a first connecting piece 114. Specifically, the first connecting piece 114 is integrally connected to the two first side pieces 113, and the first connecting piece 114 is located between the two first side pieces 113 to reduce production costs and manufacturing procedures. Furthermore, the shape of the first side piece 113 can be an arc, a semicircle, a circle, a square, etc., but the present invention is not limited thereto.

[0043] Furthermore, if Figure 3A As shown, the first plate 110 may further include two first coating layers 115 and a first fiber layer 116, wherein the first fiber layer 116 is disposed between the two first coating layers 115. Furthermore, the material of the first fiber layer 116 may include stretchable polypropylene (OPP), and the first fiber layer 116 may have a woven pattern A. The material of each of the two first coating layers 115 may include polypropylene. Thus, by configuring that the first fiber layer 116 is located between the two first coating layers 115, and the material of the first fiber layer 116 is stretchable polypropylene and the material of the first coating layer 115 is polypropylene, the effect of waterproof and wear resistance can be achieved, and the weight of the sole structure 100 can be effectively reduced. In addition, the woven pattern A of the first fiber layer 116 may be plain, twill, satin and other styles, and the present invention is not limited to the styles disclosed in the accompanying drawings.

[0044] The second plate 120 has a first surface 121 and a second surface 122, and includes two second side pieces 123 and a second connecting piece 124. Specifically, the second connecting piece 124 integrally connects the two second side pieces 123, and the second connecting piece 124 is located between the two second side pieces 123. Furthermore, the shape of the second side piece 123 can be arc, semicircular, circular, square, etc., but the present invention is not limited thereto.

[0045] Furthermore, if Figure 3BAs shown, the second plate 120 may further include two second coating layers 125 and a second fiber layer 126, wherein the second fiber layer 126 is disposed between the two second coating layers 125. Furthermore, the material of the second fiber layer 126 may include stretchable polypropylene, and the second fiber layer 126 may have a woven pattern B. The material of each of the two second coating layers 125 may include polypropylene. Thus, by configuring that the second fiber layer 126 is located between the two second coating layers 125 and the material of the second fiber layer 126 is stretchable polypropylene and the material of the second coating layer 125 is polypropylene, the effect of waterproof and wear resistance can be achieved, and the weight of the sole structure 100 can be effectively reduced. In addition, the woven pattern B of the second fiber layer 126 may be a plain weave, a twill weave, a satin weave, etc., and the present invention is not limited to the patterns disclosed in the accompanying drawings.

[0046] Two pads 130 are connected to the first plate 110 and the second plate 120, one side of one pad 130 is connected to the second surface 112 of the first plate 110, the other side of the one pad 130 is connected to the first surface 121 of the second plate 120, one side of the other pad 130 is connected to the second surface 122 of the second plate 120, and the other side of the other pad 130 is connected to the first surface 111 of the first plate 110. In this way, the arrangement of the pads 130 can provide walking comfort and flexibility, and the configuration of the two pads 130 and the first plate 110 and the second plate 120 can not only make the connection between the components more compact, but also effectively improve the manufacturing efficiency of the sole structure 100.

[0047] For example Figure 1 and Figure 4 As shown, the first connecting piece 114 and the second connecting piece 124 are located in the central portion 101 of the sole structure 100, and the first connecting piece 114 and the second connecting piece 124 are arranged side by side and staggered. In this way, the force applied by the foot to the sole during walking can be evenly dispersed, thereby protecting the foot and reducing the damage caused by uneven force. Furthermore, the width of the first connecting piece 114 is less than or equal to half of the width of each of the two first side pieces 113, and the width of the second connecting piece 124 is less than or equal to half of the width of each of the two second side pieces 123. Thus, by limiting the width of the first connecting piece 114 and the width of the second connecting piece 124, when the first connecting piece 114 and the second connecting piece 124 are arranged side by side and staggered in the central portion 101 of the sole structure 100, it is possible to avoid the reduction in the strength of the sole structure 100 due to the first connecting piece 114 and the second connecting piece 124 being squeezed against each other due to their excessive widths, and the elasticity and cushioning force of the sole structure 100 of the present invention can be greatly improved.

[0048] Furthermore, the material of the two pads 130 can be a material with foaming properties such as ethylene vinyl acetate (EVA) to provide excellent elasticity, but the present invention is not limited thereto.

[0049] For example Figure 1 and Figure 2 As shown, the sole structure 100 may further include two sole pads 140, wherein one of the two sole pads 140 may be disposed adjacent to one pad body 130 and disposed on the second surface 122 of the second plate 120, and the other of the two sole pads 140 may be disposed adjacent to the other pad body 130 and disposed on the second surface 112 of the first plate 110. Specifically, the two sole pads 140 are located on the side of the sole structure 100 facing the ground, and the material of the sole pads 140 may be a non-slip material, so that the sole pads 140 can directly contact the ground and increase the friction between the sole structure 100 and the ground, thereby reducing foot injuries caused by uneven or slippery roads when walking or exercising.

[0050] Please refer to Figures 5 to 7 , Figure 5 A schematic diagram of a shoe structure 200 according to another embodiment of the present invention is shown. Figure 6 Draw Figure 5 An exploded view of the shoe structure 200, Figure 7 Draw Figure 5 The shoe structure 200 includes an upper structure 210 and a sole structure 100, wherein the sole structure 100 in the shoe structure 200 is the aforementioned Figure 1 The sole structure 100 has the same structural details as those described in the previous paragraph and will not be described in detail here.

[0051] The sole structure 100 is connected to the upper structure 210, wherein the upper structure 210 is connected to the sole structure 100 to form a foot accommodating space (not shown). Figure 6 and Figure 7 As shown, the upper structure 210 and the sole structure 100 can be directly or indirectly bonded to form a foot accommodation space, and when the user wears the shoe structure 200, the foot accommodation space formed by the connection between the upper structure 210 and the sole structure 100 can not only accommodate the user's feet, but also protect the user from injuries caused by foreign objects directly touching the feet when walking or exercising. In this way, the new shoe structure 200 can have excellent comfort and an effect of evenly applying force to the foot, thereby improving safety and comfort.

[0052] Furthermore, if Figure 7As shown, the shoe structure 200 may further include one or more insoles 220, and the insoles 220 may be disposed between the upper structure 210 and the sole structure 100. The insoles 220 may increase the comfort of the foot and increase the elasticity of the shoe structure 200, and the material of the insoles 220 may include foam material, so that it has functions such as breathability, antibacterial, and deodorization, but the present invention is not limited thereto.

[0053] In summary of the above embodiments, the advantages of the sole structure and shoe structure of the present invention are as follows. First, the configuration that the first connecting piece of the first plate integrally connects the two first side pieces of the first plate and the second connecting piece of the second plate integrally connects the two second side pieces can reduce the production cost and manufacturing process. Second, the structural firmness can be enhanced by connecting the two pads to the first surface and the second surface of the first plate and the first surface and the second surface of the second plate respectively, and the material of the first plate and the second plate can achieve the effect of waterproof and wear resistance, and can effectively reduce the weight of the sole structure. Third, the first connecting piece and the second connecting piece are located in the central part of the sole structure and are arranged side by side and staggered with each other, so that the force applied by the foot to the sole during walking can be evenly dispersed, thereby protecting the foot and reducing the damage caused by uneven force. Fourth, by limiting the width of the first connecting piece and the width of the second connecting piece, it is possible to avoid the first connecting piece and the second connecting piece from squeezing each other due to the excessive width, thereby reducing the strength of the sole structure, and the elasticity and buffering force of the present sole structure can be greatly improved. Therefore, the novel sole structure and shoe structure have commercial application potential in related industries.

[0054] Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention.
