FIG. 1 is a schematic view of an embodiment of the firstsole layer 110 of thesole structure 10. As shown inFIG. 1 , thesole structure 10 includes a firstsole layer 110. The firstsole layer 110 has anupper surface 112 and a plurality ofopenings 116 penetrating theupper surface 112. Refer to the section view shown in theFIG. 2 . As shown in theFIG. 2 , the firstsole layer 110 has anupper surface 112 and alower surface 114. Theopenings 116 on the firstsole layer 110 penetrate theupper surface 112 and thelower surface 114. - In addition, the
sole structure 10 includes a secondsole layer 120 andspikes 130. Thespikes 130 are disposed at a side close to thelower surface 114 and correspond to theopenings 116. For example, each of theopenings 116 corresponds to aspike 130. The secondsole layer 120 envelops the firstsole layer 110, wherein a part of the secondsole layer 120 adheres to theupper surface 112, and a part of the secondsole layer 120 adheres to thelower surface 114. As shown inFIG. 2A , at the side near thelower surface 114, the secondsole layer 120 is penetrated by thespike 130 and attached to thelower surface 114. - Refer to
FIG. 2B .FIG. 2B is a partially enlarged view of the location of thespikes 130 on thesole structure 10. For concise explanation,FIG. 2B only illustrates thespike 130 and a portion adjacent to theopening 116 of the firstsole layer 110 and does not illustrate the second sole layer. As mentioned before, the firstsole layer 110 has theopening 116. Refer toFIGS. 1 and 2B . Theopenings 116 haveperipheries 118, wherein each of theopenings 116 has atubular wall 111 surrounding theperiphery 118 ofopening 116, and the tubular wall extends towards thelower surface 114. More specifically, thetubular wall 111 has a first end 111 a and asecond end 111 b. The first end 111 a connects to the firstsole layer 110. Thesecond end 111 b is the end of thetubular wall 111 opposite to the first end 111 a. As shown inFIG. 2B , thetubular wall 111 extends from the first end 111 a toward the side of thelower surface 114 and projects out. The end of thetubular wall 111 away from thelower surface 114, also known as thesecond end 111 b, contracts toward the center of theopening 116. In other words, theopening 116 tapers along the direction that thetubular wall 111 projects from thelower surface 114 to form an oblique tubular wall. - In an embodiment, the tubular wall encircles to form a closed type. For example, the
tubular wall 111 inFIG. 2B forms a closed cone with an opening to the spike in the lower part by spinning from the left side of thetubular wall 111 to its right side on an axis drawn from the spike to the opening. In other embodiment, the tubular wall may be a semi-closed type. For example, there may be gaps between two tubular walls which have a semi-circular cross section. Moreover, the shape of theopening 116 is not limited to circular. In other embodiment, the shape of the opening may be triangular or of different shapes based on design needs on different places of the first sole layer. - Moreover, as shown in
FIG. 2B , there is a gap d between thespike 130 and thecorresponding opening 116. The gap d is located between the end of thetubular wall 111 away from thelower surface 114 and thespike 130. Refer toFIG. 2A and 2B . The secondsole layer 120 passes through the gap d and is attached to thelower surface 114. In addition, the secondsole layer 120 is located on the side of thelower surface 114 that extends into theopening 116 and connects with thespike 130. Therefore, the secondsole layer 120 envelops the firstsole layer 110 and connects with thespike 130 through the gap d by extending into the openings of the firstsole layer 110. On the other hand, the secondsole layer 120 envelops thetubular wall 111; that is, it envelops the tubular wall by attaching itself to the upper surface and the lower surface and extending into the openings. -
FIG. 3 is a flow chart of the manufacturing procedure of the sole structure. As shown inFIG. 3 , the manufacturing method of the sole structure comprises step S10: forming a plurality of spikes in a mold, step S20: placing a first sole layer and leaving a gap between the first sole layer and the spikes. - Refer to
FIG. 4 , an illustration of the manufacturing procedure for the sole structure. As shown inFIG. 4 , the sole structure is formed in a mold. Themold 20 comprises anupper die 21 and alower die 22. Theupper die 21 has a plurality ofchannels 24 for injection molding. The manufacturing procedure includes forming thespikes 130 in themold 20 first and then placing the firstsole layer 110 inside themold 20. The firstsole layer 110 hasopenings 116 and there is a gap between eachspike 130 and itscorresponding opening 116. - As shown in
FIG. 3 , step S30 involves dispensing a second sole layer on the first sole layer; more specifically, dispensing an uncured second sole layer to the upper surface and the lower surface of the first sole layer in the mold. For example, by injecting the uncured second sole layer from the channel 24 (or 24 a), the uncured second sole layer dispenses onto theupper surface 112 of the firstsole layer 110 and also flows to the side of thelower surface 114 via theopenings 116 and dispenses onto thelower surface 114 of the firstsole layer 110. After the secondsole layer 120 cures, a portion of the secondsole layer 120 is attached to theupper surface 112, and another portion of the secondsole layer 120 is attached to thelower surface 114. The secondsole layer 120 located at the side of thelower surface 114 extends into the openings and connects with thespikes 130. The sole structure of the present invention improves the overall elasticity and durability. - In another embodiment, additional channels, for example 24 b, at different locations instead of corresponding to the openings are added to adjust the injection speed when the uncured second sole layer is injected.
- In another embodiment, small holes penetrating the upper surface and the lower surface are added to the first
sole layer 110, for example, at thelocation 24 b. The uncured second sole layer flows to the lower surface via the openings and the locations other than the borders of the first sole layer to adjust the uniformity of the dispensing. -
FIG. 6A is a schematic view of the dispensing of the second sole layer. As shown inFIG. 6A , the uncured second sole layer flows onto the first sole layer via the path r1 and dispenses onto theupper surface 112 via the paths r11 and r12. In addition, the uncured second sole layer flows onto thelower surface 114 through the openings via the path r1. In view ofFIG. 6A , the uncured second sole layer dispenses onto thelower surface 114 through the gap d between thespikes 130 and the firstsole layer 110 via the paths r21 and r22. Besides, the obliquetubular wall 111 guides the uncured second sole layer to flow towards the side of thelower surface 114 and prevents it from obstructing the flow of the uncured second sole layer near the gap d to provide a better flow when the uncured second sole layer is dispensed onto the lower surface through the gap. - After the second sole layer cures, the manufacturing of the sole structure is complete.
FIG. 6B is a schematic view of connecting the second sole layer with the spikes. As shown inFIG. 6B , the secondsole layer 120 is not only attached to theupper surface 112 andlower surface 114 but also extends into the locations corresponding to the openings. The secondsole layer 120 extended into the openings connects to thespikes 130 through the gap by flowing along thetubular wall 111. - In an embodiment, the first sole layer is a hard-fiber sole layer and the second sole layer is a thermoplastic-elastic sole layer. Therefore, the sole structure has better elasticity. The user's foot is not easily fatigued because the design is a thermoplastic-elastic sole layer enveloping a hard-fiber sole layer. Thus, the portion of the second sole layer which extends from the lower surface to the spikes along the tubular wall provides elasticity. In addition, the portion of the second sole layer which extends into the openings connects the side attached to the lower surface and the side attached to the upper surface to form an integral piece to provide elasticity and durability and to reduce impact when stepping on the ground, which improves protection to the feet. In addition, the second sole layer and the spikes may be identical in material so that the strain on the second sole layer is similar to that on the spikes' to keep the structure stable. However, the material of the spikes is not limited to what is mentioned above.
- In another embodiment, the first sole layer is a carbon-fiber sole layer and the second sole layer is a thermoplastic polyurethane (PTU) sole layer. Applying the carbon-fiber sole layer as the first sole layer decreases the overall weight. Applying the TPU sole layer as the second sole layer enveloping the first sole layer improves the durability of the sole structure and provides a good anti-bending effect while running
FIG. 7 shows another embodiment of thespikes 130, forming different spikes at different locations of the structure. For example, inFIG. 7 , thespikes 130 not only have the base part 132 as in the aforementioned embodiment but also have theprotruding part 134 which protrudes from the base part 132 and extends towards the upper surface. Connecting theprotruding part 134 and the portion of the second sole structure extending into the openings improves the bonding effect between thespikes 130, the firstsole layer 110 and the secondsole layer 120. Overall, the sole structure of the present invention, on one hand, provides bounciness and shock absorption through its second sole layer (PTU sole layer), and on the other hand, provides support to maintain the sole structure through its first sole layer (carbon-fiber sole layer) to prevent deformation from the force returned from ground via the spikes while running - The present invention has been described by the embodiments mentioned above. However, the embodiments are only for examples. But necessary to point out that the disclosure embodiments are not intent to limit the present invention. Conversely, any modifications and equivalent setups which are included in the scope and spirt of the present invention are under the scope of the present invention.
