Abstract
Description
Technical Field
[0001] The present application relates to the field of shoe production, and in particular to a shoe tree. Background Art
[0002] Riding boots and other leather boots have excellent protection and wear resistance, and incorporate a variety of fashion elements in their design. They can provide good support for the user's ankles and effectively protect the user's legs during outdoor activities. They are especially popular among outdoor enthusiasts, horse riding enthusiasts and fashion pursuers.
[0003] After the shoes are produced and passed the quality inspection, the next step is to pack them. Since these shoes are relatively soft, in order to reduce the wrinkles generated during storage and transportation and keep the shoes in good shape, it is usually necessary to place shoe trees at the shoe opening.
[0004] Due to the particularity of boots (the length of the shoe shaft of boots is relatively long), it is necessary to use a shoe stretcher to insert the shoe shaft along the shoe opening to prop up the shoe shaft of the boots, but the shoe shaft of such shoes has a relatively complex contour. In the prior art, the shoe stretcher is usually arranged in an integrated manner, that is, the shoe stretcher is directly shaped by the cooperation of an upper mold and a lower mold, and the shoe stretcher is placed on the upper mold or the lower mold as a whole after the mold is opened. However, due to the poor rigidity of the shoe stretcher, demolding by using a mold ejector rod may cause the shoe stretcher to be damaged or deformed, making demolding inconvenient, and the shoe stretcher is usually made in one piece, thereby increasing the production cost of the shoe stretcher. Utility Model Content
[0005] In order to reduce the production cost of a shoe tree, the present application provides a shoe tree.
[0006] The present application provides a shoe support adopting the following technical solution:
[0007] A shoe stretcher comprises a shoe stretcher body, wherein the shoe stretcher body comprises a first supporting portion and a second supporting portion. When the first supporting portion covers the second supporting portion, the formed contour is adapted to the contour of the shoe opening.
[0008] By adopting the above technical solution, the shoe stretcher is divided into a first supporting part and a second supporting part. After the first supporting part and the second supporting part are manufactured, the first supporting part and the second supporting part are covered with each other. At this time, the contour formed by the combination of the first supporting part and the second supporting part is the same as the contour of the shoe opening. The operator only needs to insert the combined first supporting part and the second supporting part into the shoe opening. Compared with the one-piece molded shoe stretcher, this method reduces the difficulty of demoulding during the production process of the shoe stretcher, plays a positive guiding role in improving the production efficiency of the shoe stretcher, thereby reducing the production cost of the shoe stretcher.
[0009] Preferably, the first supporting portion is hinged to one end of the second supporting portion close to the shoe opening.
[0010] By adopting the above technical solution, during the production process of the first support part and the second support part, one end of the first support part and the second support part close to the shoe opening is in a sticky state, so that the first support part and the second support part can be overlapped with each other relatively accurately, reducing the probability of a situation in which the shoe shaft cannot be fully supported due to position deviation when the first support part and the second support part overlap each other, and also facilitating the operator to place the shoe support body composed of the first support part and the second support part into the shoe opening.
[0011] Preferably, the first supporting portion is hinged to one end of the second supporting portion close to the sole.
[0012] By adopting the above technical solution, compared with the method of hingedly connecting one end of the first support part and the second support part close to the shoe opening, a method of hingedly connecting one end of the first support part and the second support part close to the sole is adopted. When the shoe support body composed of the first support part and the second support part is placed in the shoe opening, the overlapping part of the first support part and the second support part at the shoe opening is relatively flat, and the hinge point cannot be seen, which plays a positive guiding role in improving the appearance quality of the product.
[0013] Preferably, a holding portion is provided at one end of the first supporting portion and the second supporting portion close to the shoe opening, and the holding portion is formed by depressions of the first supporting portion and the second supporting portion along the thickness direction thereof.
[0014] By adopting the above technical solution, when the operator needs to place the shoe stretcher body composed of the first supporting part and the second supporting part into the shoe opening, the operator only needs to pinch the holding part with fingers to place the shoe stretcher body into the shoe opening without using additional auxiliary tools, thereby reducing the time for placing the shoe stretcher body into the shoe opening and playing a positive guiding role in improving the overall production efficiency.
[0015] Preferably, an ankle supporting portion is provided on the first supporting portion and the second supporting portion respectively.
[0016] By adopting the above technical solution, when the shoe stretcher body composed of the first supporting part and the second supporting part is placed in the shoe opening, the ankle supporting part located on the first supporting part and the second supporting part can just abut against the ankle of the shoe, so that the ankle of the shoe can also be propped up, so that when the shoe stretcher body is placed in the shoe shaft, the shape of the shoe is relatively full, and the number of concave points of the shoe when the shoe stretcher body is placed in the shoe shaft is reduced.
[0017] Preferably, the first supporting portion and the second supporting portion are arranged in a hollow manner on the side away from the side abutting against the inner wall of the shoe shaft.
[0018] By adopting the above technical solution, when the first supporting part and the second supporting part overlap each other, the two overlapping surfaces are hollowed out, which can reduce the weight of the shoe stretcher body compared to a solid type, and also reduce the production cost of the shoe stretcher body.
[0019] Preferably, the first supporting portion and the second supporting portion are respectively provided with clamping portions on both sides along the width direction thereof.
[0020] By adopting the above technical solution, when the first support part and / or the second support part need to be demolded during the production process, the operator only needs to pinch the clamping part with fingers to remove the first support part and / or the second support part from the mold, which to a certain extent solves the problem that the first support part and / or the second support part are difficult to remove from the mold due to smooth or uneven surfaces.
[0021] Preferably, the first supporting portion and / or the second supporting portion are provided with direction indicating marks.
[0022] By adopting the above technical solution, the operator can quickly identify the direction of the shoe stretcher main body through the direction indication marks on the first support part and / or the second support part, thereby facilitating the rapid and accurate placement of the shoe stretcher main body into the shoe opening, which to a certain extent solves the problem of needing to adjust the direction of the shoe stretcher main body or the shoe opening due to inaccurate matching between the direction of the shoe stretcher main body and the direction of the shoe opening, and reduces the time it takes to place the shoe stretcher main body into the shoe opening.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. The shoe stretcher body is composed of a first support part and a second support part, and the contour formed when the first support part and the second support part overlap each other is adapted to the shape of the shoe opening. The split production method is adopted, which reduces the demoulding difficulty during the production of the shoe stretcher body and plays a positive guiding role in reducing the production cost of the shoe stretcher;
[0025] 2. During the production of the first support part and the second support part, one end close to the shoe opening is in a hinged state, and the hinge point can be used to guide the first support part and the second support part to overlap each other relatively accurately, thereby reducing the probability that the shoe stretcher body cannot fully support the shoe opening due to deviation in the overlapping position when the first support part and the second support part overlap each other;
[0026] 3. The operator only needs to pinch the holding part with fingers to put the shoe stretcher body composed of the first supporting part and the second supporting part into the shoe without additional auxiliary tools, which simplifies the process of placing the shoe stretcher body and plays a positive guiding role in reducing the time the shoe stretcher body is placed in the shoe opening.

[0032] The following is combined with Figure 1-4 This application is described in further detail.
[0033] The present application embodiment discloses a shoe tree. Figure 1 A shoe stretcher includes a shoe stretcher body 1, which includes a first support portion 2 and a second support portion 3. When the first support portion 2 covers the second support portion 3, the contour formed matches the contour of the shoe opening. The first support portion 2 can be made of plastic material or paper material. In this embodiment, in order to improve the appearance quality of the shoe stretcher body 1, the shoe stretcher body 1 is made of paper material. The first support portion 2 and the second support portion 3 are separately produced and processed by the cooperation of an upper mold and a lower mold, and then assembled again after the production and processing are completed, so that it can adapt to shoe shafts of different lengths. Compared with a conventional one-piece shoe stretcher, the shoe stretcher body 1 formed by the combination of the first support portion 2 and the second support portion 3 can be designed according to the length of the shoe shaft, has stronger adaptability, and does not have the problem of demoulding difficulty, thereby reducing the number of defective products caused by demoulding difficulty after the shoe stretcher is produced, and plays a positive guiding role in reducing the production cost of the shoe stretcher.
[0034] Example 1
[0035] Reference Figure 1 and Figure 2 The first supporting part 2 is hinged to the second supporting part 3 at one end close to the shoe opening.
[0036] Specifically, the covering surfaces of the first support part 2 and the second support part 3 near the shoe opening are in a connected state. One implementation method is: during the production process of the first support part 2 and the second support part 3, the connection between the first support part 2 and the second support part 3 near the shoe opening is integrally formed through mold production, so that the first support part 2 and the second support part 3 are produced and manufactured at the same time, the production efficiency is higher, and there is no need to use other connecting parts to bond the first support part 2 and the second support part 3 to each other later.
[0037] Another implementation method is: the first support part 2 and the second support part 3 are processed in a split manner, and the first support part 2 and the second support part 3 are processed respectively by the cooperation of two sets of upper molds and lower molds. Compared with the method in which the first support part 2 and the second support part 3 are formed at the same time, the split forming method reduces the number of the first support part 2 and the second support part 3 being formed at the same time. Due to the appearance of defective products (such as cracks, unevenness, etc.) in the first support part 2 and / or the second support part 3, the first support part 2 and the second support part 3 become scrapped at the same time. The operator can remove the defective products in the first support part 2 and / or the second support part 3 by sorting, and connect the first support part 2 and the second support part 3 to each other through a connector (such as adhesive paper), thereby reducing the number of defective products in the production process.
[0038] Example 2
[0039] Reference Figure 4 The difference from Example 1 is that the first supporting portion 2 is hinged to the second supporting portion 3 at one end close to the sole, and the hinge method is the same as that of Example 1, which will not be described in detail here.
[0040] The implementation principle of Example 2 is as follows: because the first support part 2 and the second support part 3 are hinged at one end close to the sole, when the operator combines the first support part 2 and the second support part 3 to form the shoe stretcher main body 1, the connection between the first support part 2 and the second support part 3 is close to the sole, but there is no hinge point at one end of the shoe stretcher main body 1 located at the shoe opening, so that when the operator covers the first support part 2 and the second support part 3 with each other and places the formed shoe stretcher main body 1 in the shoe opening, the covering surface of the first support part 2 and the second support part 3 located at the shoe opening is relatively flat, thereby improving the appearance quality of the first support part 2 and the second support part 3 when placed in the shoe opening.
[0041] Reference Figure 1-Figure 4 In any figure, a gripping portion 4 is provided at one end of the first supporting portion 2 and the second supporting portion 3 close to the shoe opening, and the gripping portion 4 is formed by the first supporting portion 2 and the second supporting portion 3 being recessed downward along the thickness direction thereof.
[0042] Specifically, the pinching parts 4 located on the first support part 2 and the second support part 3 are respectively extruded through the cooperation of the upper mold and the lower mold to form grooves for the operator's fingers to place. Therefore, after the operator covers the first support part 2 and the second support part 3 with each other, he uses his fingers to pinch the two pinching parts 4 respectively, so that the first support part 2 and the second support part 3 are in a state of being pressed against each other, reducing the deviation of the matching position of the first support part 2 and the second support part 3 when placing the first support part 2 and the second support part 3 in the shoe opening, so that when the shoe stretcher main body 1 is placed in the shoe opening, the shape of the shoe shaft is relatively full; at the same time, the operator or user can quickly and conveniently place the shoe stretcher main body 1 in the shoe opening, or take out the shoe stretcher main body 1 along the shoe shaft through the pinching part 4.
[0043] Reference Figure 1-Figure 4 In any figure, the first support part 2 and the second support part 3 are respectively provided with an ankle support part 5, and the two ankle support parts 5 are respectively formed as a whole with the first support part 2 and the second support part 3 by mold extrusion, and when the shoe support body 1 formed by covering the first support part 2 and the second support part 3 is placed in the shoe shaft, the two ankle support parts 5 are located at the ankle of the shoe shaft (in order to make the user more comfortable when wearing the shoes, the ankle of the shoe shaft is a convex setting, and when the user's foot wears the shoe, the ankle is located in the convexity), thereby propping up the ankle of the shoe shaft, making it easier for the user to intuitively understand the details of the shoe, and also making the appearance of the shoe fuller.
[0044] Continue to refer to Figure 3 The first supporting portion 2 and the second supporting portion 3 are arranged in a hollow manner on the side away from the side abutting against the inner wall of the shoe shaft.
[0045] Specifically, the first support portion 2 and the second support portion 3 are extruded and formed by using an upper mold and a lower mold, so that the thickness of any part of the first support portion 2 and the second support portion 3 is in the same state. Compared with an integrally formed shoe stretcher, the overall weight of the shoe stretcher main body 1 formed when the first support portion 2 and the second support portion 3 are covered is greatly reduced, and the amount of raw materials used in making the shoe stretcher main body 1 is also reduced, which plays a positive role in reducing the manufacturing cost of the shoe stretcher.
[0046] Reference Figure 1-Figure 4 In any of the figures, the first supporting portion 2 and the second supporting portion 3 are respectively provided with clamping portions 6 on both sides along the width direction thereof.
[0047] Specifically, the arrangement and function of the clamping portion 6 on the first supporting portion 2 and the clamping portion 6 on the second supporting portion 3 are the same, and the matching relationship between the first supporting portion 2 and the clamping portion 6 is described below.
[0048] The clamping portion 6 is integrally formed with the first support portion 2 along the width direction of the first support portion 2 by mold extrusion, and is recessed inwardly at two edges along the width direction of the first support portion 2, and the clamping portion 6 can be located at any point of the first support portion 2 along its width direction. In the present embodiment, the clamping portion 6 is located on the first support portion 2 near the ankle support portion 5.
[0049] Therefore, after the first support part 2 and the second support part 3 are extruded through the cooperation of the upper mold and the lower mold, the first support part 2 and the second support part 3 are still located on the lower mold. The operator uses his fingers or other clamping tools to take out the first support part 2 and the second support part 3 along the lower mold through the clamping part 6 without changing the shape of the first support part 2 and / or the second support part 3, thereby reducing the number of defective products.
[0050] Reference Figure 1 The first supporting portion 2 and / or the second supporting portion 3 are provided with a direction indicating mark 7. In the present embodiment, the direction indicating mark 7 is provided as an indicating arrow, and can also be provided as a text indicating mark. The indicating arrow is integrally formed with the first supporting portion 2 and / or the second supporting portion 3 by mold extrusion. In the present embodiment, the indicating arrow has the following three setting modes: ① an indicating arrow is provided on the first supporting portion 2, but no indicating arrow is provided on the second supporting portion 3; ② no indicating arrow is provided on the first supporting portion 2, but an indicating arrow is provided on the second supporting portion 3; ③ both the first supporting portion 2 and the second supporting portion 3 have indicating arrows. When the shoe support body 1 needs to be placed in the shoe shaft, the direction of the shoe support body 1 can be quickly distinguished by the arrow indicating mark, so that the shoe support body 1 can be accurately placed in the shoe shaft, thereby reducing the probability of the situation that the shoe support body 1 and the shoe shaft are not aligned, and the shoe support body 1 needs to be adjusted again / or the direction of the shoe shaft needs to be adjusted.
[0051] The implementation principle of a shoe stretcher in the embodiment of the present application is as follows: by using the cooperation of the upper mold and the lower mold, the first support part 2 and the second support part 3 are produced and processed respectively. When the first support part 2 and the second support part 3 overlap each other, the contour formed is adapted to the contour of the shoe shaft, so that the shoe stretcher body 1 can adapt to shoe shafts of different lengths. Compared with the traditional one-piece molded shoe stretcher, the combination of the first support part 2 and the second support part 3 can be customized according to the length of the shoe shaft, thereby improving the adaptability. At the same time, the number of defective products caused by the difficulty of demolding during the production process is effectively reduced.
[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
