TECHNICAL FIELD
[0001] The utility model relates to the technical field of footwear manufacturing, in particular to a vamp and shoe back structure. BACKGROUND
[0002] In a one-piece leisure shoe without a shoelace and a tongue, the front end of the ankle of a user is prone to rubbing against the front side of the shoe opening during walking due to the lack of fixation by a shoelace and constraint by a tongue, and the vamp of the one-piece leisure shoe is made harder than a general leisure shoe to ensure the constraint on the foot, which is prone to causing the user's foot to be injured in the process of repeated rubbing. SUMMARY
[0003] The utility model aims at providing a vamp and shoe back structure to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0004] To solve the above technical problems, the utility model adopts the following technical scheme:
[0005] Firstly, the utility model provides a vamp and shoe back structure, which comprises a vamp surrounding piece, a shoe back surrounding piece and an elastic piece, the vamp surrounding piece, the elastic piece and the shoe back surrounding piece are combined to form a shoe opening at part of the edge, the middle of the rear edge of the vamp surrounding piece is concave, the concave part is connected with the elastic piece, and the elastic modulus of the elastic piece is smaller than that of the vamp surrounding piece.
[0006] Specifically, the vamp and shoe back structure are laid flat, the middle of the rear edge of the vamp surrounding piece is concave in the top view, the rear edge of the vamp surrounding piece is formed with a first connecting edge and a second connecting edge having a distance difference in the front-rear direction, the second connecting edge is symmetrically distributed relative to the center line in the left-right direction of the vamp surrounding piece and is connected with the first connecting edge, the second connecting edge is collinear with the original rear edge of the vamp surrounding piece, the edge degree of the elastic piece in the front-rear direction is greater than that in the left-right direction, the front edge of the elastic piece is connected with the first connecting edge, the short edge of the elastic piece is collinear with the second connecting edge, the edge of the shoe back surrounding piece in the left-right direction is connected with the second connecting edge and the short edge of the elastic piece, and the rear edge of the elastic piece and the front edge of the shoe back surrounding piece combine to form a shoe opening for the foot to pass through. The front edge, the edge in the left-right direction of the vamp surrounding piece and the rear edge of the shoe back surrounding piece are used to connect the shoe sole, and the elastic modulus of the elastic piece is smaller than that of the vamp surrounding piece.
[0007] It needs to be explained that the front and back of the above-mentioned scheme refers to the front and back of the shoe upper surrounding piece and the shoe back upper surrounding piece when they are laid flat. Since the front edge, left and right direction edges of the shoe upper surrounding piece and the rear edge of the shoe back upper surrounding piece are used to connect the sole, after connecting the sole, the shoe back upper surrounding piece and the shoe upper surrounding piece will change in the vertical direction, so that the shoe back upper surrounding piece and the shoe upper surrounding piece can fit the human foot. At this time, the front and back direction of the shoe back upper surrounding piece will change relatively, becoming the relative up and down direction, that is, the front of the shoe back upper surrounding piece will become vertically arranged relative to when the sole is not connected, becoming relatively upward.
[0008] The front half of the shoe opening is provided as an elastic piece, and the elastic modulus of the elastic piece is smaller than the elastic modulus of the shoe upper. The part of the shoe upper in contact with the front side of the ankle is softer and elastic than the shoe upper surrounding piece, so as to reduce the friction of the front end of the shoe opening on the front side of the user's ankle and improve the comfort of the shoe opening. When the user puts his foot into the shoe, the traditional one-foot shoe upper structure has a force on the surface of the human foot when the user's foot is put into the shoe. The setting of the elastic piece plays a buffering role. By setting the elastic piece, the user will deform the elastic piece when wearing the shoe. After the user wears the shoe, it returns to its original state, which can improve the comfort of wearing. The left and right end edges of the elastic piece are connected to the shoe back upper surrounding piece, so that the elastic piece forms a half-circle shoe opening and has a better deformation effect, making the user wear more comfortably. The inner recessed position is arranged at the rear edge of the shoe upper surrounding piece, so that the elastic piece is located at the central position of the shoe upper structure and uniformly contacts the front of the human ankle.
[0009] As an extension of the above-mentioned scheme, the shoe upper surrounding piece and the shoe back upper surrounding piece are integrally formed with the elastic piece. By integrally forming the shoe upper and the shoe back upper structure provided by the present application, the trimming process can be reduced, and the parts do not need to be separately formed and then sewn together. The connection between the shoe back upper surrounding piece, the connecting piece and the shoe upper surrounding piece is more secure, and the service life of the elastic piece is improved.
[0010] As an extension of the above-mentioned scheme, the front edge of the shoe upper surrounding piece is provided with a flat edge, and the left and right direction edges of the shoe upper surrounding piece are provided with serrated edges. It needs to be explained that the front edge and the left and right direction edges refer to the front and rear edges of the shoe upper surrounding piece in the laid flat state. By such a setting, it is convenient for the producer to subsequently use the shoe upper and the shoe back upper structure provided by the present application for fusion forming with the sole, thereby improving the fusion strength.
[0011] As an extension of the above-mentioned scheme, the shoe back upper surrounding piece includes a front surrounding piece and a rear surrounding piece, and the front surrounding piece and the rear surrounding piece jointly enclose a shoe back upper sleeve for filling the shoe back upper elastic member. The rear surrounding piece connects the elastic piece and the shoe upper surrounding piece.
[0012] Generally, the production of the shoe back and the shoe upper structure is to put the shoe back elastic element between the front and back pieces, then melt in the mold, and then sew with the shoe upper piece, while the shoe upper and shoe back structure provided by the utility model can make the shoe upper piece, the front piece and the back piece complete in the same textile process, then insert the shoe back elastic element into the shoe back sleeve, and then melt the shoe back sleeve and the shoe back elastic element together, so as to reduce the cutting process.
[0013] As an extension of the above scheme, the back piece is further provided with a skirt piece, which extends along the upper part of the back piece. It should be noted that the skirt piece extends along the upper part of the back piece, which means that the shoe back piece extends along the front part of the back piece in the flat state. Since it is a high-heeled shoe, the user will step on the shoe back when wearing the shoe, so that the foot is put into the shoe, at this time the shoe back will expand backward, the skirt piece is generally set as an integral part of the back piece, therefore, the skirt piece has the same performance as the back piece, so that the skirt piece can help the shoe back to reset when the shoe back expands backward.
[0014] As an extension of the above scheme, the distance between the shoe back sleeve and the skirt piece is 5 to 10 mm. The distance between the shoe back sleeve and the skirt piece refers to the distance between the top end of the shoe back sleeve and the top end of the skirt piece in the state that the shoe back piece stands up. Through such a setting, the skirt piece can provide better resetting ability for the shoe back.
[0015] The length of the skirt piece in the height direction of the shoe back piece is 5 mm. Since the shoe upper and shoe back structure provided by the utility model has an upwardly extending shoe back sleeve, the top of the front piece is bent downward, the front piece extends backward and downward to connect with the position 5 mm below the top of the back piece, and the upper area forms a skirt piece, which can hide the interface between the front piece and the back piece.
[0016] As an extension of the above scheme, the distance that the elastic piece extends in the front-back direction is 5 to 10 mm. Obviously, setting the entire shoe upper as an elastic elastic piece cannot provide sufficient wrapping for the user's foot, therefore, the elastic piece only occupies a part of the shoe upper piece, and the distance that the elastic piece extends in the length direction of the shoe upper piece is set to 5 to 10 mm, which does not affect the overall supportability of the shoe upper, and can improve the comfort of the shoe upper structure.
[0017] As an extension of the above scheme, the back edge of the shoe back piece is provided with a connecting piece, and the length of the connecting piece extending downward is 5 to 8 mm.
[0018] The rear edge of the rear quarter of the upper refers to the front edge of the rear quarter of the upper in the flat state, and the lower edge of the rear quarter of the upper is provided with a connecting piece when the rear quarter of the upper is connected with the sole, that is, the lower edge of the rear quarter of the upper. By providing a connecting piece of 5-8 mm, the lower edge of the rear quarter of the upper can be wrapped and clamped by the connecting piece, and the connection is more firm during welding.
[0019] As an extension of the above scheme, the elastic modulus of the connecting piece is less than the elastic modulus of the rear quarter of the upper.
[0020] Since the connecting piece is used to connect the sole and needs to be welded with the rear quarter of the upper, the elastic modulus of the connecting piece is less than the elastic modulus of the rear quarter of the upper, so that the connecting piece can be stretched longer and more easily wrapped around the rear quarter of the upper.

[0030] Referring to Figures 1 to 3 , the following will give several embodiments of the vamp and the back collar structure of the utility model.
[0031] As Figure 1 and Figure 3 shown, a vamp and a back collar structure, comprising: a vamp 100, a back collar 200 and an elastic piece 400, the part of the edge of the vamp 100, the elastic piece 400, the back collar 200 is enclosed to form a shoe opening 300, the middle of the back edge of the vamp 100 is concave, the concave part is connected with the elastic piece 400, and the elastic modulus of the elastic piece 400 is less than the elastic modulus of the vamp 100.
[0032] Specifically, the vamp and the back collar structure are laid flat, in the top view state, the middle of the back edge of the vamp 100 is concave, so that the back edge of the vamp 100 forms a first connecting edge 101 and a second connecting edge 102 with distance difference in the front-back direction, the second connecting edge 102 is symmetrically distributed relative to the middle line in the left-right direction of the vamp 100 and connected with the first connecting edge 101, the second connecting edge 102 is collinear with the original back edge of the vamp 100, the length of the edge of the elastic piece 400 in the front-back direction is greater than the length of the edge of the elastic piece 400 in the left-right direction, the front edge of the elastic piece 400 is connected with the first connecting edge 101, the short edge of the elastic piece 400 is collinear with the second connecting edge 102, and the edge of the back collar 100 in the left-right direction is connected with the second connecting edge 102 and the short edge of the elastic piece 400 at the same time, so that the back edge of the elastic piece 400 and the front edge of the back collar 200 enclose the shoe opening for the foot to enter. The front edge, the edge in the left-right direction of the vamp 100 and the back edge of the back collar 200 are used to connect the sole, and the elastic modulus of the elastic piece 400 is less than the elastic modulus of the vamp 100.
[0033] It needs to be explained that the front and back of the above scheme refer to the front and back of the vamp piece 100 and the back piece 200 when they are laid flat. Since the front edge, left and right edges of the vamp piece 100 and the rear edge of the back piece 200 are used to connect the sole, after connecting the sole, the back piece 200 and the vamp piece 100 will change in the vertical direction, so that the back piece 200 and the vamp piece 100 can fit the person's foot. At this time, the front and back direction of the back piece 200 will change relatively, becoming the relative up and down direction, that is, the front of the back piece 200 will become vertically arranged relative to when the sole is not connected, becoming relatively upward.
[0034] The front half of the shoe opening 300 is provided as an elastic piece 400, and the elastic modulus of the elastic piece 400 is less than that of the vamp piece 100. This can make the part of the vamp structure in contact with the front side of the ankle softer than the vamp piece 100 and have elasticity, so as to reduce the friction of the front end of the shoe opening 300 on the front side of the user's ankle and improve the comfort of the shoe opening 300. When the user puts his foot into the shoe, the traditional one-foot shoe vamp structure has a force on the user's foot when the user's foot is put into the shoe. The setting of the elastic piece 400 plays a buffering role. By adopting the setting of the elastic piece 400, the user will deform the elastic piece 400 when wearing the shoe, and the elastic piece 400 will return to its original state after the user wears the shoe, thereby improving the comfort of wearing. The left and right end edges of the elastic piece 400 are connected to the back piece 200, so that the elastic piece 400 forms a half-circle shoe opening and has a better deformation effect, making the user wear more comfortable. The inner recessed position is arranged at the rear edge of the vamp piece 100, so that the elastic piece 400 is located at the central position of the vamp structure and uniformly contacts the front of the user's ankle.
[0035] Since the one-foot casual shoe is generally produced using the flyknit process, the elasticity of the elastic piece 400 is greater than that of the vamp piece 100. Specifically, the elastic piece 400 can be formed on the vamp piece 100 by locally changing the yarn density or material during the production of the flyknit vamp.
[0036] In order to maximize the comfort provided by the elastic piece 400, the left and right ends of the elastic piece 400 in the width direction of the vamp piece 100 are connected to the back piece 200, and the elastic piece 400 extends in the length direction of the vamp piece 100 by 5 to 10 mm.
[0037] In order to make the production process simpler, the vamp 100 and the back collar 200 can be integrally formed with the elastic piece 400, the front edge of the vamp 100 is provided with a flat edge, and the lower edge of the vamp 100 in the left-right direction is provided with a sawtooth-shaped edge. The lower edge of the back collar 200 in the up-down direction is provided with a connecting piece 205, and the length of the connecting piece 205 in the up-down direction is 5-8 mm.
[0038] By arranging the elastic piece 400 on the side of the shoe opening 300 towards the toe, the part of the vamp of the one-piece shoe in contact with the front side of the ankle has greater elasticity than the vamp 100, so as to reduce the friction of the front end of the shoe opening 300 on the front side of the user's ankle and improve the comfort of the shoe opening 300. When the user puts on the one-piece shoe, the front side of the shoe opening 300 has a force on the user's instep, and the arrangement of the elastic piece 400 plays a buffering role. By arranging the elastic piece 400, the user can deform the elastic piece 400 when putting on the shoe, and the elastic piece 400 returns to its original shape after the user puts on the shoe, thereby improving the comfort of wearing.
[0039] As shown in Figure 2 In some embodiments, in order to facilitate the later installation of the back collar elastic piece 500 to realize the function of a one-piece shoe, the back collar 200 includes a front piece 201 and a rear piece 202, and the front piece 201 and the rear piece 202 enclose a back collar sleeve 203 for filling the back collar elastic piece 500. This arrangement is more time-saving than separately forming various components of the back collar and then combining them.
[0040] Because of the one-piece shoe, the user will step on the back collar when putting on the shoe, and the instep will be put into the shoe, at which time the back collar will expand backward. The rear piece can be further provided with a skirt piece 204 extending above the rear piece 202, so that when the back collar expands backward, the skirt piece 204 can help the back collar return to its original position. Because the skirt piece 204 is generally arranged as an integral part of the rear piece 202, the skirt piece 204 has the same performance as the rear piece 202.
[0041] In order to make the skirt piece 204 provide better returning ability for the back collar, the distance between the back collar sleeve 203 and the skirt piece 204 is 5-10 mm.
[0042] Since the vamp and the rear upper structure provided by the utility model has the upwardly extending rear upper sleeve 203, the top of the front panel 201 is bent downwards, that is, the front panel 201 is connected to the position 5mm below the top of the rear panel 202, so that the upper area forms the skirt panel 204, which can hide the interface between the front panel 201 and the rear panel 202. Therefore, the length of the skirt panel 204 in the height direction of the rear upper panel 200 is 5mm.
[0043] The preferred embodiments of the utility model are specifically described above, but the utility model creation is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the utility model, and these equivalent modifications or replacements are all included in the range defined by the claims of the application.
