Description
Technical Field
[0001] The present application relates to the field of shoe production, and in particular to an adjustable shoe tree. Background Art
[0002] After the shoes are produced, they are usually propped up with shoe trees to reduce wrinkles or deformation caused by squeezing during storage and transportation, so that the shape of the shoes is relatively full.
[0003] After the shoes are produced, they need to be designed according to the shape of the shoe shaft. Because there are many types of shoes and the sizes of shoes are different, in order to make the shoe stretcher have a good supporting effect on the shoes, it is necessary to design shoe stretchers of various sizes to adapt to shoes of different sizes.
[0004] In the actual production process of shoe stretchers, in order to meet the design requirements of shoe stretcher sizes, it is necessary to design a variety of cutters and shoe stretcher forming molds of different specifications to complete the processing of shoe stretchers. However, the shoes themselves are updated and iterated at a fast speed. After the current products are produced, some cutters and forming molds cannot meet the production requirements of the next generation of shoe stretchers and have to be discarded, which indirectly increases the production cost of the shoe stretchers. Utility Model Content
[0005] In order to reduce the production cost of the shoe tree, the present application provides an adjustable shoe tree.
[0006] The adjustable shoe support provided in this application adopts the following technical solution:
[0007] 1. An adjustable shoe stretcher, comprising a shoe stretcher main body, the shoe stretcher main body comprising a toe support portion, a shoe body support portion and a shoe opening support portion, the two ends of the shoe body support portion are respectively connected to the toe support portion and the shoe opening support portion, the toe support portion is used to support the toe of the shoe, the shoe body support portion is used to support the shoe body, and the shoe opening support portion is used to support the heel of the shoe, the shoe opening support portion comprises a first support plate and a second support plate, one end of the first support plate is fixedly connected to one end of the shoe body support portion along the width direction thereof, one end of the second support plate is fixedly connected to the other end of the shoe body support portion along the width direction thereof, and the other ends of the first support plate and the second support plate are detachably connected to each other.
[0008] By adopting the above technical scheme, the toe support part, the body support part and the shoe opening support part are fixedly connected in sequence to form a shoe stretcher main body, the toe of the shoe is supported by the toe support part, the body of the shoe is supported by the body support part, and the shoe opening of the shoe is supported by the shoe opening support part. When the shoe stretcher main body is placed in the shoe, the shoe stretcher main body props up the shoe, making the shoe outline relatively full and reducing wrinkles generated during transportation or storage. At the same time, because the first supporting piece and the second supporting piece are detachably connected to each other, when facing shoes of different sizes, the operator only needs to separate the first supporting piece and the second supporting piece from each other, adjust them to a suitable length, and then fix the first supporting piece and the second supporting piece again, so that the shoe stretcher main body can adapt to shoes of different sizes, without designing a shoe stretcher for each size of shoe, which plays a positive guiding role in reducing the production cost of the shoe stretcher.
[0009] Preferably, a first clamping groove is provided on the first supporting sheet, and a plurality of second clamping grooves are provided on the second supporting sheet. The first clamping groove can be clamped with any one of the second clamping grooves.
[0010] By adopting the above technical solution, when the size of the shoe support body needs to be adjusted, the size enclosed by the first clamping groove and the second clamping groove clamped therewith can be matched with the size of the shoe by switching between the plurality of second clamping grooves and the first clamping groove.
[0011] Preferably, the first supporting sheet is provided with a plurality of first engaging grooves, and the second supporting sheet is provided with a second engaging groove, and the second engaging groove can be engaged with any one of the first engaging grooves.
[0012] By adopting the above technical solution, when the size of the shoe support body needs to be adjusted, the size enclosed by the first clamping groove and the second clamping groove connected thereto can be matched with the size of the shoe by switching between the first clamping groove and the second clamping groove connected thereto.
[0013] Preferably, the first supporting sheet is provided with a plurality of first engaging grooves, and the second supporting sheet is provided with a plurality of second engaging grooves, and any one of the first engaging grooves can be engaged with any one of the second engaging grooves.
[0014] By adopting the above technical solution, any one of the snap-in grooves provided on the first supporting plate can be snap-fitted with any one of the snap-in grooves provided on the second supporting plate, thereby making the size enclosed between the first supporting plate and the second supporting plate more flexible to adjust, making it more adaptable to shoes of different sizes, and reducing the gap between the shoe support body and the shoe when the shoe support body is placed in the shoe.
[0015] Preferably, the ends of the shoe body supporting portion and the toe supporting portion which abut against the sole are open-type.
[0016] By adopting the above technical solution, compared with a closed shoe stretcher, the end of the shoe body support part and the toe support part of the shoe stretcher main body that abuts against the sole is open-type, thereby reducing the raw materials required for the production of the shoe stretcher main body. At the same time, the shoe stretcher main body can be preliminarily cut through a plate to have a planar contour of the shoe stretcher main body, and the shoe stretcher main body is shaped again through a mold. Compared with a closed shoe stretcher, the shoe stretcher main body is easier to demould, thereby reducing defective products caused by damage or deformation of the shoe stretcher due to demoulding difficulties.
[0017] Preferably, the first bending parts are respectively provided at both ends of the shoe body supporting part where the shoe sole abuts.
[0018] By adopting the above technical scheme, the distance between the sole and the upper of the shoe body can be different according to the different functions of the shoes (for example, sports shoes are looser and leather shoes are more compact). Therefore, when facing shoes with different shoe body sizes, the operator can bend the first bending part to adjust the height of the shoe body support part so that it can adapt to different types of shoes. At the same time, if the two ends where the shoe body support part abuts against the sole directly abut against the insole of the shoe, the supporting force of the shoe support part on the sole directly acts on the insole of the shoe. When the user takes out the shoe stretcher body along the shoe opening, an indentation will appear at the abutment point between the insole of the shoe and the shoe stretcher support part, thereby affecting the appearance quality of the shoe insole. Therefore, when the first bending part of the shoe stretcher body is bent and placed in the shoe, the contact area between the shoe body support part and the sole is increased by the first bending part, so as to reduce the force acting on the insole by the shoe body support part, thereby reducing the indentation on the insole.
[0019] Preferably, the second bending parts are respectively provided at both ends of the shoe opening support part abutting against the sole.
[0020] By adopting the above technical solution, according to different shoe categories (such as sports shoes and leather shoes), in sports shoes, the toe of the shoe is usually looser, but in leather shoes, the shoe body to the toe is usually gradually narrowed. Therefore, facing toes of different shapes, the operator can adjust the toe support part through the second bending part, so that it can support shoes of different categories, thereby improving the adaptability of the shoe stretcher body; at the same time, it can also increase the contact area between the toe support part and the sole, so as to reduce the force of the toe support part on the insole, thereby reducing the indentation on the insole.
[0021] Preferably, the first bending portion is provided with a plurality of rows of first auxiliary guide bending holes along its height direction, and the second bending portion is provided with a plurality of rows of second auxiliary guide bending holes along its height direction.
[0022] By adopting the above technical solution, when it is necessary to bend the first bending portion and / or part, the operator can quickly bend the first bending portion and / or the second bending portion through the guiding effect of the first auxiliary guide bending hole and / or the second auxiliary guide bending hole, so that the bending part is relatively flat and the wrinkles at the bending part are reduced.
[0023] Preferably, the shoe stretcher main body is suitable for left shoes and right shoes / or the shoe stretcher main body includes a left shoe stretcher main body and a right shoe stretcher main body.
[0024] By adopting the above technical solution, the shoe tree main body can support both the left shoe and the right shoe, and has strong adaptability; or the left shoe tree main body is used to support the left shoe, and the right shoe tree main body is used to support the right shoe.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] 1. The shoe stretcher body composed of the toe support part, the body support part and the shoe opening support part supports the shoe, thereby reducing deformation or wrinkles in the storage or transportation of the shoe; in shoes of different sizes, the operator can change the size enclosed by the first support sheet and the second support sheet to meet the support requirements of shoes of different sizes, and fix the first support sheet and the second support sheet to each other after adjusting them to a suitable length, so that the shoe stretcher body can adapt to shoes of different sizes, without having to set a shoe stretcher for each size of shoe, which plays a positive guiding role in reducing the production cost of the shoe stretcher;
[0027] 2. A first clamping groove is provided on the first support sheet, and a second clamping groove is provided on the second support sheet. Through the cooperation of the first clamping groove and the second clamping groove, the size of the first support sheet and the second support sheet can be flexibly adjusted. When adjusted to fit the current shoe, the first clamping groove and the second clamping groove can be mutually clamped and cooperated, so that the first support sheet and the second support sheet are stably connected, thereby reducing the shaking of the shoe support body when placed in the shoe;
[0028] 3. When it is necessary to bend the first bending portion and / or part, the operator can quickly bend the first bending portion and / or the second bending portion through the guiding effect of the first auxiliary guide bending hole and / or the second auxiliary guide bending hole, so that the bending part is relatively flat and the wrinkles at the bending part are reduced.

DETAILED DESCRIPTION
[0035] The following is combined with Figure 1-5 This application is described in further detail.
[0036] The present application embodiment discloses an adjustable shoe support. Figure 1 The shoe support body 1 is a shoe support body 11, a shoe support body 12 and a shoe opening support body 13. The two ends of the shoe support body 12 are respectively connected to the shoe support body 11 and the shoe opening support body 13. The shoe support body 11 is used to support the toe of the shoe, the shoe support body 12 is used to support the shoe body, and the shoe opening support body 13 is used to support the heel of the shoe. At the same time, the ends of the shoe support body 11 and the shoe support body 12 that abut against the sole are open-type, that is, when the shoe support body 1 is placed in the shoe, the side of the shoe support body 1 that abuts against the sole is in a non-closed state, thereby reducing the raw materials required for the production of the shoe support body 1. The shoe support body 1 can be preliminarily cut through a plate to have a planar contour of the shoe support body 1, and then the shoe support body 1 is shaped through a mold. Compared with a closed shoe support, the shoe support body 1 is easier to demould, thereby reducing the probability of cracking or deformation of the shoe support body 1 during the demoulding process.
[0037] Correspondingly, since the left shoe and the right shoe are symmetrically arranged, the shoe stretcher main body 1 can be suitable for the left shoe and the right shoe. However, in the present embodiment, in order to enable the shoe stretcher main body 1 to have a good supporting effect on both the left shoe and the right shoe stretcher main body 1, the shoe stretcher main body 1 is also distinguished between the left shoe stretcher main body 1 and the right shoe stretcher main body 1. The left shoe stretcher main body 1 is only used to support the left shoe, and the right shoe stretcher main body 1 is only used to support the right shoe. However, the left shoe stretcher main body 1 and the right shoe stretcher main body 1 are also symmetrically arranged, and the manufacturing method and components are the same. They are collectively referred to as the shoe stretcher main body 1 in the following specification, and are described in detail.
[0038] Furthermore, the shoe opening support portion 13 includes a first support piece 131 and a second support piece 132, one end of the first support piece 131 is fixedly connected to one end of the shoe body support portion 12 along its width direction, one end of the second support piece 132 is fixedly connected to the other end of the shoe body support portion 12 along its width direction, and the other ends of the first support piece 131 and the second support piece 132 are detachably connected to each other. Therefore, for shoes of different sizes, the operator can adapt the first support piece 131 and the second support piece 132 to the current shoes by changing the length of the matching. There is no need to design a shoe stretcher for each size of shoes, which reduces the production cost of the shoe stretcher to a certain extent.
[0039] Example 1
[0040] Reference Figure 1 A first snap-in groove 2 is provided on the first supporting piece 131, and a plurality of second snap-in grooves 3 may be provided on the second supporting piece 132. The first snap-in groove 2 may be snap-fitted with any second snap-in groove 3. The first snap-in groove 2 is formed by a depression from one end of the first supporting piece 131 close to the shoe opening to one end close to the sole, and at the same time, a plurality of second snap-in grooves 3 are formed by a depression from one end of the second supporting piece 132 close to the sole to one end close to the shoe opening. In the present embodiment, three second snap-in grooves 3 are provided, and the three second snap-in grooves 3 are evenly distributed on the second supporting piece 132 along the length direction of the second supporting piece 132.
[0041] The implementation principle of Example 1 is: the operator can engage the first engaging groove 2 with any second engaging groove 3 to adjust the size enclosed by the first supporting plate 131 and the second supporting plate 132 so as to meet the support requirements of shoes of different sizes.
[0042] Example 2
[0043] The difference from Example 1 is that, referring to Figure 2 The first supporting piece 131 may be provided with a plurality of first snap-in grooves 2, and the second supporting piece 132 may be provided with a second snap-in groove 3. In the present embodiment, three first snap-in grooves 2 are provided, and the three first snap-in grooves 2 are formed by the first supporting piece 131 being recessed downward from one end close to the shoe opening to one end close to the sole, and the second snap-in groove 3 is formed by the second supporting piece 132 being recessed downward from one end close to the sole to one end close to the shoe opening. The operator can engage the second snap-in groove 3 with any one of the first snap-in grooves 2, thereby adjusting the size enclosed by the first supporting piece 131 and the second supporting piece 132, so that the size can meet the support requirements of shoes of different sizes.
[0044] Example 3
[0045] The difference from Example 1 and Example 2 is that, referring to Figure 3 The first support sheet 131 may be provided with a plurality of first snap-fitting grooves 2, and the second support sheet 132 may be provided with a plurality of second snap-fitting grooves 3. In this embodiment, three first snap-fitting grooves 2 and three second snap-fitting grooves 3 are respectively provided. The three first snap-fitting grooves 2 are formed by the first support sheet 131 being concave downward from one end close to the shoe opening to one end close to the sole, and the three second snap-fitting grooves 3 are formed by the second support sheet 132 being concave downward from one end close to the sole to one end close to the shoe opening, and the three first snap-fitting grooves 2 are connected along the first support sheet 131. The length direction is evenly distributed on the first support piece 131, and the three second clamping grooves 3 are evenly distributed on the second support piece 132 in the length direction. The operator can clamp and match any one of the first clamping grooves 2 with any one of the second clamping grooves 3, and the adjustment range is wider, so that the size adjustment surrounded by the first support piece 131 and the second support piece 132 can be more delicate, so that it can meet the support requirements of shoes of different sizes, and reduce the gap between the shoe support body 1 and the shoe when the shoe support body 1 is placed in the shoe.
[0046] It should be noted that, refer to Figure 4 and Figure 5 The first clamping groove 2 in the first to third embodiments can also be formed by the first support piece 131 being recessed downward from one end close to the sole to one end close to the shoe opening, and the second clamping groove 3 can also be formed by the second support piece 132 being recessed downward from one end close to the shoe opening to one end close to the sole, so that when the first clamping groove 2 and the second clamping groove 3 are clamped together, the first support piece 131 and the second support piece 132 are locked with each other and are at the same height, thereby improving the appearance quality of the shoe stretcher body 1. Because the first clamping groove 2 and the second clamping groove 3 are clamped together, the stability of the first support piece 131 and the second support piece 132 is improved, and to a certain extent, the problem that the connection between the first support piece 131 and the second support piece 132 is loose, thereby affecting the supporting effect of the shoe stretcher body 1 on the shoe is solved.
[0047] Reference Figure 1-Figure 4In any figure, the first bending parts 4 are respectively provided at the two ends where the shoe body support part 12 abuts against the sole. According to the functional characteristics of different shoes (such as sports shoes are usually loose, while leather shoes are more compact), the gaps between the shoe body and the sole of different types of shoes are different. In order to adapt to different types of shoes, the operator can adjust the height of the shoe body support part 12 by adjusting the first bending part 4, so that the shoe support body 1 can provide appropriate support for the shoe body of different types of shoes. At the same time, if the shoe body support part 12 directly contacts the insole of the shoe, when the user takes out the shoe support body 1 from the shoe, it may leave an indentation on the insole, affecting the appearance of the shoe. Therefore, the operator bends the first bending part 4 and places it inside the shoe to increase the contact area between the shoe body support part 12 and the sole, reduce the pressure of the shoe body support part 12 on the insole, and thus reduce the indentation on the insole.
[0048] Reference Figure 1-Figure 4 In any figure, the second bending parts 5 are respectively provided at the two ends where the shoe opening support part 13 abuts against the sole. Depending on the type of shoes (such as sports shoes and leather shoes), in sports shoes, the toe of the shoe is usually looser, but leather shoes are usually gradually narrowed along the shoe body to the toe. Therefore, facing toes of different shapes, the operator can adjust the toe support part 11 through the second bending part 5, so that it can support shoes of different types, thereby improving the adaptability of the shoe stretcher main body 1; at the same time, it can also increase the contact area between the toe support part 11 and the sole to reduce the force of the toe support part 11 on the insole, thereby reducing the indentation on the insole.
[0049] Reference Figure 4 The first bending portion 4 is provided with several rows of first auxiliary guide bending holes 6 along its height direction, and the second bending portion 5 is provided with several rows of second auxiliary guide bending holes 7 along its height direction. In the present embodiment, the first auxiliary guide bending holes 6 and the second auxiliary guide bending holes 7 are respectively arranged in three rows, and are respectively evenly distributed on the first bending portion 4 and the second bending portion 5 along the height direction of the first bending portion 4 and the second bending portion 5. At the same time, the first auxiliary guide bending holes 6 can be set to be hole-shaped or slot-shaped. When it is necessary to bend the first bending portion and / or the second bending portion, the operator can quickly bend the first bending portion 4 and / or the second bending portion 5 through the guiding effect of the first auxiliary guide bending holes 6 and / or the second auxiliary guide bending holes 7, so that the bending portion is relatively flat and the wrinkles at the bending portion are reduced.
[0050] The implementation principle of an adjustable shoe stretcher in the embodiment of the present application is as follows: the shoe stretcher body 1 composed of a toe support portion 11, a body support portion 12 and a shoe opening support portion 13 supports the shoe to reduce deformation or wrinkles generated during storage or transportation of the shoe; for shoes of different sizes, the operator can change the size enclosed by the first support piece 131 and the second support piece 132 to meet the support requirements of shoes of different sizes, and after adjusting the first support piece 131 and the second support piece 132 to a suitable length, fix them to each other, so that the shoe stretcher body 1 can adapt to shoes of different sizes, without designing a shoe stretcher for each size of shoe, which plays a positive guiding role in reducing the production cost of the shoe stretcher.
[0051] 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.
