[0005] The combined shoe according to the embodiment of the present invention has at least the following beneficial effects: the combined shoe comprises a shoe body and a combined body, wherein the shoe body comprises a sole, a front upper and a rear upper, the front upper and the rear upper being connected to the front end and the rear end of the sole respectively, so as to jointly define a wearing cavity for a human foot to wear; the combined body comprises an insole connecting piece and an upper connecting piece, the rear end of the insole connecting piece being connected to the lower end of the upper connecting piece, and in the combined state, the user can insert the combined body into the wearing cavity so that the insole connecting piece is connected to the upper end of the sole, and the insole connecting piece is connected to the upper through the insole connecting piece. The connection of the connecting pieces enables the upper connecting piece to fit and connect with the front end of the back upper. The arrangement of the assembly helps to enhance the anti-bending performance of the back upper of the combination shoe. When the user steps the foot from the back to the front into the inner cavity of the shoe, the upper connecting piece and the back upper can jointly bear the pressure of the foot, thereby avoiding the problem of the back upper of the combination shoe collapsing forward, thereby playing a role in assisting the human foot to smoothly enter the wearing cavity. The combination shoe can be made easier to wear through the cooperation of the assembly and the shoe body.

[0006] According to some embodiments of the present invention, the hardness of the upper connecting piece is greater than the hardness of the back upper.

[0007] Specifically, the hardness of the upper connecting piece is greater than the hardness of the back piece. By differentiating the hardness of the upper connecting piece and the back piece, the combination shoe can enhance the hardness of the back piece of the combination shoe while maintaining overall wearing comfort, which is beneficial to enhancing the bending resistance of the back piece of the combination shoe, and is beneficial to enabling the combination shoe to withstand the forward pressure of the foot without collapsing, thereby helping the human foot to smoothly penetrate the wearing cavity.

[0008] According to some embodiments of the present invention, the upper portion of the rear end of the upper connecting piece is a forward convex upper arc portion, and the lower portion of the rear end of the upper connecting piece is a backward convex lower arc portion, and the shape of the rear upper is adapted to the shape of the lower arc portion.

[0009] Specifically, the upper part of the rear end of the upper connecting piece is a forward-convex upper arc-shaped part, and the lower part is a backward-convex lower arc-shaped part, that is, the rear end of the upper connecting piece is "S"-shaped, which conforms to the shape of the human foot. The forward-convex upper arc-shaped part can assist the human foot to enter the wearing cavity. The human foot can enter the wearing cavity along the forward-convex surface of the upper arc-shaped part, making the combination shoe easier to wear, and the forward-convex upper arc-shaped part can improve the wrapping of the human foot, and the backward-convex lower arc-shaped part is adapted to the shape of the human heel. The shape of the back upper is adapted to the shape of the lower arc-shaped part, which is conducive to improving the fit between the back upper and the upper connecting piece, and the backward-convex lower arc-shaped part improves the wrapping performance of the human heel.

[0010] According to some embodiments of the present invention, the upper arc portion has a bending section that gradually bends upward from front to back, the upper end of the bending section is located above the upper end of the back panel, and the rear end of the bending section is located behind the rear end of the back panel.

[0011] Specifically, the upper arc portion has a bending section that gradually bends upward from front to back, the upper end of the bending section is located above the upper end of the back upper, and the rear end of the bending section is located behind the rear end of the back upper, that is, the upper end of the bending section is tilted back to the rear of the back upper. When the user wears the combination shoe, the user's foot enters the wearing cavity from back to front. At this time, the user's foot first abuts against the upper end of the bending section, and then slides into the wearing cavity along the arc surface of the upper arc portion. The shape setting of the upper arc portion is conducive to assisting the user to complete the wearing of the shoes, and is conducive to avoiding the problem of the user stepping on the back upper of the shoe when wearing. When the user wears the combination shoe, it is conducive to reducing the scratching of the back upper on the human heel.

[0012] According to some embodiments of the present invention, the width of the upper connecting piece in the left-right direction gradually decreases from bottom to top, the thickness of the upper connecting piece gradually becomes thicker from the upper end toward the middle of the upper arc portion, gradually becomes thinner from the middle of the upper arc portion toward the junction of the upper arc portion and the lower arc portion, gradually becomes thicker from the junction of the upper arc portion and the lower arc portion toward the middle of the lower arc portion, and gradually becomes thinner from the middle of the lower arc portion toward the lower end; and / or,

[0013] The upper connecting piece has a built-in support piece.

[0014] Optionally, the width of the upper connecting piece in the left-right direction gradually decreases from bottom to top, that is, the lower end of the upper connecting piece is wider, which can meet the support and wrapping performance of the human heel, while the upper end of the upper connecting piece is narrower to meet the requirement of the upper connecting piece to deform at the shoe opening. Specifically, the thickness of the upper connecting piece gradually becomes thicker from the upper end toward the middle of the upper arc portion, gradually becomes thinner from the middle of the upper arc portion toward the junction of the upper arc portion and the lower arc portion, gradually becomes thicker from the junction of the upper arc portion and the lower arc portion toward the middle of the lower arc portion, and gradually becomes thinner from the middle of the lower arc portion toward the lower end, that is, the upper end of the upper connecting piece is thinner, which meets the requirements of the shoe opening. The upper end of the upper connecting piece needs to be turned back to expand the shoe opening under the downward pressure of the human foot, which plays a role in assisting the user to put on the shoes. The middle part of the upper connecting piece is thinner. When the human foot passes into the wearing cavity along the upper arc part, the upper arc part can be turned back relative to the lower arc part to assist the user to complete the wearing. The lower end of the upper connecting piece is thinner, which meets the use requirement of connecting the lower end of the upper connecting piece with the insole connecting piece; optionally, the upper connecting piece is equipped with a supporting piece. The setting of the supporting piece is conducive to enhancing the bending resistance of the upper connecting piece, which is conducive to avoiding the problem of users stepping on the back of the shoe of the combination shoe.

[0015] According to some embodiments of the present invention, the insole connecting piece and the upper connecting piece are formed separately, and the rear end of the insole connecting piece is overlapped and connected with the lower end of the upper connecting piece.

[0016] Specifically, the usage requirements of the upper connecting piece and the insole connecting piece are different. The upper connecting piece needs to withstand pressure from the back to the front and needs to have high bending resistance, while the insole connecting piece is used to connect with the sole of the human foot to improve the user's wearing experience. The insole connecting piece and the upper connecting piece of the combination shoe are formed separately to meet the usage requirements of the upper connecting piece and the insole connecting piece respectively. The rear end of the insole connecting piece is overlapped and connected with the lower end of the upper connecting piece to achieve a stable connection between the upper connecting piece and the insole connecting piece. Under the mutual limiting action of the insole connecting piece and the wearing cavity, it is conducive to fixing the position of the insole connecting piece in the wearing cavity. Through the connection between the insole connecting piece and the upper connecting piece, the upper connecting piece is made to abut against the front end of the back upper to improve the fit between the combination and the shoe body.

[0017] According to some embodiments of the present invention, the insole connecting piece and the upper connecting piece are integrally formed parts.

[0018] Specifically, in order to improve the connection stability between the insole connecting piece and the upper connecting chain, the insole connecting piece and the upper connecting piece of the combination shoe can be an integrally molded part to improve the connection stability between the rear end of the insole connecting piece and the lower end of the upper connecting piece, thereby avoiding the problem of breakage at the connection between the upper connecting piece and the upper connecting piece during wearing.

[0019] According to some embodiments of the present invention, a plurality of ventilation holes are provided at the front and / or back parts.

[0020] Specifically, a plurality of ventilation holes are provided at the front upper and / or the back upper. The provision of the ventilation holes is conducive to improving the breathability of the combination shoe and is conducive to avoiding the problem of stuffy feet in the combination shoe.

[0021] According to some embodiments of the present invention, the shoe upper and / or the back are made of rubber, EVA, PU or resin materials.

[0022] Specifically, the upper and / or the back are made of rubber, EVA (ethylene-vinyl acetate copolymer), PU (polyurethane) or resin materials, and a plurality of ventilation holes are provided at the front and / or the back, that is, the shoe body is a hole shoe style. The combination shoe is conducive to enhancing the bending resistance of the hole shoe at the back of the shoe through the coordination and connection between the combination body and the shoe body, which helps to avoid the problem of the user stepping on the back of the shoe when wearing the hole shoe, and plays a role in assisting the human foot to smoothly penetrate the wearing cavity.

[0023] According to some embodiments of the present invention, the left end of the front upper is connected to the left end of the back upper, and the right end of the front upper is connected to the right end of the back upper to form a ring-shaped shoe upper.

[0024] The left end of the front upper is connected to the left end of the back upper, and the right end of the front upper is connected to the right end of the back upper to form a ring-shaped upper. The setting of the upper is conducive to enhancing the wrapping of the user's foot and making the upper connecting piece fit with the front end of the back upper.

[0039] Reference Figures 1 to 5As shown, a combined shoe according to an embodiment of the present invention includes a shoe body 200 and a combined body 100 .

[0040] Reference Figure 1 、 Figure 2 and Figure 3 As shown, the shoe body 200 includes a sole 220, a front upper 230 and a back upper 210, wherein the front upper 230 and the back upper 210 are respectively connected to the front end and the back end of the sole 220, the left end of the front upper 230 is connected to the left end of the back upper 210, and the right end of the front upper 230 is connected to the right end of the back upper 210, that is, the front upper 230 and the back upper 210 together form a ring, and the front upper 230, the sole 220 and the back upper 210 together define a wearing cavity 240, which can be worn by a human foot.

[0041] Reference Figure 1 、 Figure 4 and Figure 5 As shown, the assembly 100 includes an upper connecting piece 120 and an insole connecting piece 110 , and the lower end of the upper connecting piece 120 is connected to the rear end of the insole connecting piece 110 , and the upper connecting piece 120 and the insole connecting piece 110 are arranged in an L shape.

[0042] Reference Figure 1 、 Figure 2 and Figure 3 As shown, the combined shoe has an assembled state and a separated state. The separated state is when the combined body 100 and the shoe body 200 are completely separated. The assembled state is when the combined body 100 is inserted into the wearing cavity 240, and the lower end of the insole connecting piece 110 is connected to the upper end of the sole 220, and the upper connecting piece 120 is fitted and connected to the front end of the back cover 210. The shape of the lower end of the insole connecting piece 110 is adapted to the shape of the upper end of the sole 220.

[0043] Reference Figure 1 and Figure 2 As shown, in the assembled state, the user can insert the assembly 100 into the wearing cavity 240, and place the insole connecting piece 110 into the wearing cavity 240. The inner wall of the wearing cavity 240 faces the outer edge of the insole connecting piece 110, so that the position of the insole connecting piece 110 in the wearing cavity 240 is relatively fixed. The connection between the insole connecting piece 110 and the upper connecting piece 120 facilitates the upper connecting piece 120 to fit and connect with the front end of the back cover 210.

[0044] Reference Figure 1 、 Figure 2 and Figure 3As shown, the combination shoe is advantageously enhanced in its anti-bending performance at the shoe back by the arrangement of the shoe upper connecting piece 120. When the user steps the foot into the inner cavity of the shoe from the back to the front, the shoe upper connecting piece 120 and the shoe back 210 can jointly bear the pressure of the foot, thereby avoiding the problem of the combination shoe collapsing forward at the shoe back, thereby playing a role in assisting the human foot to smoothly enter the wearing cavity 240. The combination shoe can be made easier to wear by the cooperation between the combination body 100 and the shoe body 200.

[0045] Reference Figure 1 、 Figure 2 and Figure 3 As shown, for example, the shoe body 200 may be a ready-made shoe that lacks support at the back of the shoe. The user can combine and connect the combination 100 with the shoe body 200 to form the combined shoe and enhance the bending resistance of the shoe body 200, making the shoe body 200 easier to wear.

[0046] Reference Figure 1 、 Figure 2 and Figure 3 As shown, it is understandable that, considering the different usage requirements of the combination shoe at the back of the shoe and the sole 220, the combination shoe needs to withstand the pressure of the user's foot at the back of the shoe and guide the user to wear it, so the hardness requirement of the combination shoe at the back of the shoe is higher.

[0047] Reference Figure 1 、 Figure 4 and Figure 5 As shown, specifically, the hardness of the upper connecting piece 120 is greater than the hardness of the back 210. By differentiating the hardness of the upper connecting piece 120 and the hardness of the back 210, the combination shoe enhances the hardness of the back of the shoe while maintaining overall wearing comfort, which is beneficial to enhancing the bending resistance of the back of the shoe of the combination shoe, and is beneficial to enabling the combination shoe to withstand the forward pressure of the foot without collapsing, thereby playing a role in assisting the human foot to smoothly penetrate the wearing cavity 240.

[0048] Reference Figure 1 、 Figure 4 and Figure 5As shown, specifically, based on the different usage requirements of the upper connecting piece 120 and the insole connecting piece 110, the upper connecting piece 120 needs to withstand pressure from the back to the front and needs to have higher anti-bending performance, while the insole connecting piece 110 is used to connect with the sole of the human foot to improve the user's wearing experience. The insole connecting piece 110 and the upper connecting piece 120 of the combination shoe are formed separately, so that the hardness of the upper connecting piece 120 is greater than the hardness of the back 210 and the hardness of the insole connecting piece 110, so as to enhance the anti-bending performance of the combination shoe at the back of the shoe, and improve the user's foot feel when wearing the combination shoe, meeting the usage requirements of the upper connecting piece 120 and the insole connecting piece 110.

[0049] The rear end of the insole connecting piece 110 is overlapped and connected with the lower end of the upper connecting piece 120 to achieve a stable connection between the upper connecting piece 120 and the insole connecting piece 110. The outer edge of the insole connecting piece 110 and the inner wall surface of the wearing cavity 240 limit each other, which is conducive to fixing the position of the insole connecting piece 110 in the wearing cavity 240. Through the connection between the insole connecting piece 110 and the upper connecting piece 120, it is conducive to making the upper connecting piece 120 abut against the front end of the rear cover 210, so as to improve the fit between the combination 100 and the shoe body 200.

[0050] Specifically, a residual edge is provided at the lower edge of the upper connecting piece 120, and the residual edge is overlapped with the rear edge of the insole connecting piece 110. The residual edge and the insole connecting piece 110 are sewn or bonded to achieve a fixed connection between the upper connecting piece 120 and the insole connecting piece 110.

[0051] It should be understood that in some other embodiments, specifically, in order to improve the connection stability between the insole connecting piece 110 and the upper connecting chain, the insole connecting piece 110 and the upper connecting piece 120 of the combination shoe can be an integrally molded part to improve the connection stability between the rear end of the insole connecting piece 110 and the lower end of the upper connecting piece 120, thereby avoiding the problem of breakage at the connection between the upper connecting piece 120 and the upper connecting piece 120 during wearing.

[0052] Specifically, the upper connecting piece 120 and the insole connecting piece 110 can be integrally formed by a foaming process or a hot pressing process.

[0053] It should be understood that in some other embodiments, a connecting piece is provided at the lower end of the upper connecting piece 120, and a receiving groove is provided at the insole connecting piece 110. The connecting piece can be inserted into the receiving groove, and the connection between the upper connecting piece 120 and the insole connecting piece 110 is achieved by the mutual limitation of the connecting piece and the receiving groove.

[0054] Reference Figure 1 、 Figure 4 and Figure 5 As shown, it can be understood that in this embodiment, the width of the upper connecting piece 120 gradually decreases from bottom to top. That is, the lower end of the upper connecting piece 120 is wider to provide support and wrapping for the human heel, while the upper end of the upper connecting piece 120 is narrower to meet the requirement of deformation of the upper connecting piece 120 at the shoe opening.

[0055] Reference Figure 1 、 Figure 3 and Figure 5 As shown, the upper portion of the rear end of the upper connecting piece 120 is a forward convex upper arc portion 121 , and the lower portion of the rear end of the upper connecting piece 120 is a backward convex lower arc portion 122 , and the shape of the rear upper 210 is adapted to the shape of the lower arc portion 122 .

[0056] Reference Figure 1 、 Figure 3 and Figure 5 As shown, the rear end of the upper connecting piece 120 is in an "S" shape, which conforms to the shape of the human foot. The forward-convex upper arc portion 121 can assist the human foot in entering the wearing cavity 240. The human foot can enter the wearing cavity 240 along the forward-convex surface of the upper arc portion 121, making the combined shoe easier to wear. The forward-convex upper arc portion 121 can improve the wrapping performance of the human foot, and the rear-convex lower arc portion 122 is adapted to the shape of the human heel. The shape of the rear upper 210 is adapted to the shape of the lower arc portion 122, which is beneficial to improving the fit between the rear upper 210 and the upper connecting piece 120. The rear-convex lower arc portion 122 improves the wrapping performance of the human heel.

[0057] Reference Figure 1 、 Figure 2 and Figure 3 As shown, it can be understood that the upper arc portion 121 has a bending section 1211 that bends gradually upward from front to back, the upper end of the bending section 1211 is located above the upper end of the back cover 210, and the rear end of the bending section 1211 is located behind the rear end of the back cover 210.

[0058] Reference Figure 1 、 Figure 2 and Figure 3 As shown, the upper end of the bent section 1211 is tilted back to the rear of the back cover 210. When the user wears the combination shoe, the user's foot enters the wearing cavity 240 from the back to the front. At this time, the user's foot first abuts against the upper end of the bent section 1211, and then slides into the wearing cavity 240 along the arc surface of the upper arc portion 121. The shape setting of the upper arc portion 121 is helpful in assisting the user to complete the wearing of the shoes, and is helpful in avoiding the problem of the user stepping on the back cover of the shoe when wearing it. When the user wears the combination shoe, it is helpful to reduce the scratching of the back cover 210 on the human heel.

[0059] Reference Figure 1 、 Figure 4 and Figure 5 As shown, it can be understood that the thickness of the upper connecting piece 120 gradually becomes thicker from the upper end toward the middle of the upper arc portion 121, gradually becomes thinner from the middle of the upper arc portion 121 toward the junction of the upper arc portion 121 and the lower arc portion 122, gradually becomes thicker from the junction of the upper arc portion 121 and the lower arc portion 122 toward the middle of the lower arc portion 122, and gradually becomes thinner from the middle of the lower arc portion 122 toward the lower end.

[0060] Reference Figure 1 、 Figure 4 and Figure 5 As shown, the upper end of the upper connecting piece 120 is thinner, which meets the use requirement that the upper end of the upper connecting piece 120 needs to be turned back to expand the shoe opening under the downward pressure of the human foot, and plays a role in assisting the user to put on the shoes. The middle part of the upper connecting piece 120 is thinner. When the user inserts into the wearing cavity 240 along the upper arc portion 121, the upper arc portion 121 can be turned back relative to the lower arc portion 122 to assist the user to complete the wearing. The lower end of the upper connecting piece 120 is thinner, which meets the use requirement of connecting the lower end of the upper connecting piece 120 with the insole connecting piece 110.

[0061] Reference Figure 1 、 Figure 4 and Figure 5 As shown, when a user wears the combined shoe, the human foot can be inserted from the back to the front at an inclined downward angle. The human foot first contacts the bent section 1211 at the upper end of the upper arc portion 121 and can slide along the arc surface of the upper arc portion 121 to assist the human foot in entering the wearing cavity 240 surrounded by the front upper 230, the back upper 210 and the shoe body 200, which helps to avoid the problem of the human foot stepping on the back upper of the shoe and collapsing it. As the human foot continues to penetrate the shoe body 200, the human foot can exert outward pressure on the upper connecting piece 120 located in the wearing cavity 240 and the shoe upper located at the shoe opening. The upper arc portion 121 of the upper connecting piece 120 can be folded backward relative to the lower arc portion 122, thereby driving the shoe upper to expand backward to expand the caliber of the shoe opening, so that the user can insert the foot into the inner cavity of the shoe body 200. After the user's foot penetrates the inner cavity of the shoe body 200, the squeezing force on the upper connecting piece 120 at the shoe opening gradually decreases. Under the action of its own elasticity, the upper connecting piece 120 can rebound forward and fit with the human foot to achieve wrapping and support for the human foot. Compared with traditional shoes that require manual assistance to put on, the combination shoe, through the coordination and connection of the combination body 100 and the shoe body 200, allows the user to put on the combination shoe by simply inserting the foot into the inner cavity of the shoe body 200 without the need for manual assistance, making it easier to put on and take off.

[0062] Reference Figure 1 、 Figure 2 and Figure 3As shown, it can be understood that, specifically, the shoe body 200 can be a hole shoe style, and a plurality of ventilation holes 250 are provided at the front upper 230 and the back upper 210. The provision of the ventilation holes 250 is conducive to improving the breathability of the combination shoe and helping to avoid the problem of stuffy feet in the combination shoe.

[0063] Reference Figure 1 、 Figure 2 and Figure 3 As shown, the upper and back 210 are made of elastic materials such as rubber, EVA, PU, or resin. This combined shoe, through the coordination and connection between the assembly 100 and the shoe body 200, helps enhance the bending resistance of the back of the Crocs, preventing the back from collapsing when the user steps on the Crocs, and assisting the foot in smoothly entering the wearing cavity 240. The front 230 and back 210 can be integrally formed by foaming to enhance the connection stability between the front 230 and back 210.

[0064] It should be understood that, in some other embodiments, the front upper 230 is provided with a plurality of ventilation holes 250. The provision of the ventilation holes 250 is conducive to improving the breathability of the combination shoe and helping to avoid the problem of stuffy feet in the combination shoe.

[0065] It should be understood that, in some other embodiments, the back cover 210 is provided with a plurality of ventilation holes 250. The provision of the ventilation holes 250 is conducive to improving the breathability of the combination shoe and helping to avoid the problem of stuffy feet in the combination shoe.

[0066] It should be understood that in other embodiments, the shoe body 200 may be a casual sports shoe, and the front upper 230 and / or the back upper 210 may be made of materials such as mesh or knitted fabric. The front upper 230 and the back upper 210 may be integrally woven to enhance the connection stability between the front upper 230 and the back upper 210; alternatively, the front upper 230 and the back upper 210 may be fixedly connected by sewing or bonding.

[0067] It should be understood that in some other embodiments, the upper connecting piece 120 is equipped with a support piece. The provision of the support piece is conducive to enhancing the bending resistance of the upper connecting piece 120 and helping to avoid the problem of users stepping on the back of the combination shoe to collapse.

[0068] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
