Description

Technical Field

[0001] The present application relates to the technical field of shoe supports, in particular to an adjustable shoe support. Background Art

[0002] Shoe trees are tools used to maintain the shape of shoes and support the structure of shoes. They can be inserted into shoes when not being worn to help the shoes maintain their original shape and avoid wrinkles and deformation. At the same time, shoe trees can also help shoes breathe and dry, extending the service life of shoes.

[0003] After searching, the announcement number is CN207574622U, which discloses a multi-purpose adjustable shoe support with adjustable length and width, including a toe support, a threaded handwheel, a heel support and a threaded rod, the toe support is connected to the threaded rod, the heel support is connected to the threaded handwheel through an internal threaded hole, the threaded handwheel is movably connected to the threaded rod through a cylindrical through hole in the middle, and the toe mold includes a right toe mold and a left toe mold, and the right toe mold and the left toe mold are respectively provided with fastening screws, which are adjusted by the screw handwheel and are suitable for shoes of different lengths; the expansion of the right toe mold and the left toe mold is adjusted by the threaded rod, which is suitable for shoes of different widths; the fastening effect of the through-hole fastening screw can easily disassemble and install the right toe mold and the left toe mold without tools, so that the toe mold can be replaced more easily, and it can also be suitable for different shoe types. Therefore, the utility model has strong versatility, convenient maintenance, and is suitable for mass production.

[0004] However, existing shoe stretchers often use a single shoe stretcher to support a pair of shoes. Since the curvatures of the insteps of the left and right feet of a human body are symmetrical, the internal support of the shoe by a single shoe stretcher may not fit the instep position of the shoe well due to the different curvatures of the insteps of the left and right feet, thereby reducing the internal support of the shoe.

[0005] Moreover, although the existing shoe stretchers can adjust the distance between the front support and the rear support according to the shoe size, iron parts are often used to adjust and connect the front support and the rear support. Since the market demand for shoe stretchers is large, shoe stretchers are needed to support unworn shoes at shopping mall counters or daily households. When shoe stretchers with iron parts are mass-produced, the manufacturing cost of the shoe stretchers will inevitably increase. Therefore, how to reduce the cost while also being able to adjust the distance between the front support and the rear support to adapt to shoes of different sizes and ensure effective support for the shoes is worth solving.

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0034] See also Figure 1-5 , the utility model provides the embodiment:

[0035] like Figure 1-2 As shown, the adjustable shoe support includes a left foot oblique support and a right foot oblique support, which are symmetrically arranged. According to the symmetry of the left and right shoes of the human body, the left and right shoes can be supported respectively by the left and right oblique supports, and the left and right oblique supports both include a shoe upper support 1 for supporting the front of the shoe, and a plurality of groups of ventilation holes 11 are arranged on the surface of the shoe upper support 1, and the ventilation hole 11 is arranged at the toe position as a single ventilation hole 11, and the ventilation hole 11 is arranged at the shoe upper position. At least three groups of air holes 11 are provided and each group of air holes 11 consists of two air holes 11. The air holes 11 are located at the upwardly raised position of the upper support 1 and are provided as a single air hole 11 and two air holes 11. The single air hole 11 and the two air holes 11 are arranged in parallel. The air holes 11 can ensure that the upper support 1 supports the shoe head and also plays a role of ventilation, so that when the shoe is stored, the odor in the shoe can be dissipated through the air holes 11 of the upper support 1.

[0036] In order to save costs while maintaining the support of the vamp 1 for the head part of the shoe, the top surface of the vamp 1 located at the instep is an upwardly raised arc structure, and the top surface of the vamp 1 is vertically curved from the bulge to the edges on both sides, so that the interior of the vamp 1 is a hollow structure. While ensuring the height of the vamp 1, the upwardly raised arc structure can also provide support for the forefoot part of the shoe for the vamp 1, thereby reducing costs while also supporting the forefoot part of the shoe.

[0037] One end of the bottom surface of the upper support 1 is clamped with one end of the adjusting connecting rod 2, and the other end of the adjusting connecting rod 2 is clamped with the heel support 3 for supporting the heel of the shoe. The distance between the upper support 1 and the heel support 3 is adjusted by adjusting the installation position of the connecting rod 2 on the heel support 3.

[0038] Specifically, Figure 5 As shown, a support portion 31 is integrally formed at the bottom of the heel support 3, and the side wall of the support portion 31 is an arc structure. The support portion 31 is a curved cone structure from top to bottom. The arc structure of the side wall of the support portion 31 can support the heel portion on the inner side of the shoe, thereby supporting the heel of the shoe. The curved cone structure makes it easy for the heel support 3 to slide to the heel position of the shoe after the upper support 1 is first inserted into the head of the shoe, thereby facilitating installation.

[0039] like Figure 4 As shown, two connecting plates 12 are integrally formed at one end of the bottom surface of the upper support 1, and the two connecting plates 12 are symmetrically arranged on the bottom surface of the upper support 1. A first clamping hole 13 is penetrated through the side wall of the connecting plate 12, and the bottom surface of the connecting plate 12 to the first clamping hole 13 is inwardly opened. The adjusting link 2 includes a first pin column 23 and a second pin column 24. An inner groove 21 is formed on the bottom surface of the adjusting link 2, and a reinforcing rib 22 is integrally formed on the top surface of the inner groove 21. The opening of the inner groove 21 can reduce the materials required for the production cost of the adjusting link 2, and the setting of the reinforcing rib 22 can also ensure that the material is reduced while also strengthening the support and non-deformation property of the adjusting link 2.

[0040] A first pin 23 is integrally formed at one end of the adjusting link 2, and a second pin 24 is integrally formed at the other end of the adjusting link 2. The first pin 23 is engaged with the first engaging hole 13 formed in the side wall of the connecting plate 12 and is rotatably connected thereto.

[0041] like Figure 4 and Figure 5As shown, by squeezing the first pin 23 from the inward opening on the bottom surface of the connecting plate 12 into the first clamping hole 13, one end of the adjusting link 2 can be installed between the two connecting plates 12 at the bottom end of the upper support 1, and the bottom surface of the heel support 3 is integrally formed with two mounting plates 34, one of the mounting plates 34 has a side wall with multiple through holes 35 equidistantly formed, and the side wall of the other mounting plate 34 has multiple second clamping holes 36 respectively formed according to the positions of the multiple through holes 35. The structure of the second clamping hole 36 is arranged in the same way as the structure of the first clamping hole 13, the two ends of the second pin 24 are plugged into one of the through holes 35, and the other end of the second pin 24 is clamped into one of the second clamping holes 36.

[0042] When in use, one end of the second pin 24 on the other end of the adjusting link 2 is inserted into one of the through holes 35 selected according to the shoe size length, and then the other end of the second pin 24 is engaged with the second engaging hole 36 at the corresponding position, so that the upper support 1 is assembled into a shoe support by installing the adjusting link 2 and the heel support 3;

[0043] The installation position of the second pin 24 on the adjusting connecting rod 2 on the heel support 3 can be adjusted according to the length of the shoe size to adapt to different shoe size lengths.

[0044] Furthermore, a first hollow groove 32 is opened inside the supporting portion 31, and a second hollow groove 33 is opened inside the heel support 3. By opening the first hollow groove 32 and the second hollow groove 33, while ensuring the support of the heel support 3, the production materials of the heel support 3 can also be reduced, thereby reducing costs.

[0045] It is worth mentioning that the upper support 1, adjustment rod 2 and heel support 3 of the present application are all made of plastic material. While ensuring the adjustable function, they can also provide better support for the shoes, while also effectively reducing the production cost, and are suitable for mass production.

[0046] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
