Description

Technical Field

[0001] This utility model relates to the field of shoe support technology, specifically to a shoe support frame. Background Technology

[0002] In the vast field of shoemaking and footwear maintenance, shoe trees play a crucial role as an indispensable auxiliary tool, widely used in shoe shaping, maintenance, and size adjustment. However, traditional shoe tree structures are often relatively simple in design and have limited functionality, mainly focusing on supporting specific parts of the shoe and lacking sufficient flexibility. This design limitation prevents shoe trees from fully meeting the precise support needs of both the entire shoe and specific areas, leading to underutilization and potential waste of their function.

[0003] More importantly, most shoe trees on the market currently use a uniform design, failing to fully consider the subtle differences in shape and size between the left and right feet. This "one-size-fits-all" design makes it difficult for shoe trees to achieve ideal fit and expansion effect, thus affecting the user experience and comfort. Therefore, we propose a shoe support frame. Utility Model Content

[0004] One of the technical problems this application aims to solve is to break through the limitations of traditional shoe support design and achieve flexible and precise support for the entire shoe and specific areas.

[0005] To solve the above-mentioned technical problems, this application provides a shoe support frame, including an expanded foot, with two expanded feet respectively for the left and right feet, and each including a foot last shell and a foot expansion unit. The foot expansion unit is disposed inside the foot last shell, and its expansion drive shaft end is located outside the foot last shell.

[0006] It also includes:

[0007] The main control rod is detachably connected to the foot expansion unit, so as to set the foot expansion unit to drive the foot last shell to expand;

[0008] The heel expansion unit is installed on the main control rod to cooperate with the foot last shell to expand the heel.

[0009] In some embodiments, a polygonal groove is formed at the end of the drive shaft of the foot expansion unit, and a polygonal insertion part adapted to the polygonal groove is integrally formed at the end of the main control rod to detachably connect the main control rod and the foot expansion unit.

[0010] In some embodiments, the end of the main control lever away from the polygonal mating portion is hook-shaped.

[0011] In some embodiments, the heel support unit includes a mounting ring rotatably mounted on the outside of the main control rod, the mounting ring having a continuous external thread on its outer side, and a heel support body threaded onto the mounting ring.

[0012] In some embodiments, a polygonal grip is provided at the end of the mounting ring.

[0013] In some embodiments, the main control rod includes a hook portion and two extension rods, the ends of the two extension rods are rotatably connected to the hook portion, and the ends of the two extension rods are polygonal insertion portions, and the two extension rods are each provided with a heel expansion support unit.

[0014] The utility model has at least the following beneficial effects:

[0015] 1. By setting two expansion soles for the left and right feet respectively, and equipping them with a foot last shell and foot expansion unit, precise expansion of the inside of the shoe is achieved, effectively solving the problem that traditional shoe trees cannot accurately fit the differences in shape between the left and right feet, thus improving wearing comfort and expansion effect.

[0016] 2. The detachable connection design between the main control rod and the foot expansion unit allows users to flexibly assemble or disassemble the shoe support according to actual needs. Especially when expanding the foot independently on a single shoe, it can ensure effective independent expansion of the foot and also allows the main control rod to be reused for expansion of multiple feet, eliminating the need to equip multiple supports, effectively saving costs, and making it easy to store and carry.

[0017] 3. The addition of the heel support unit, working in conjunction with the forefoot support unit, can provide comprehensive support to the front and back of the shoe as needed.

[0018] 4. The multi-sided grip and hook-shaped main control rod design allows users to easily hold and hang the shoe trees, simplifying the operation process and improving the user experience.

[0019] 5. The main control bar adopts a double extension bar design, which not only enhances the stability of the shoe support and the uniformity of the expansion effect, but also provides users with more usage options and flexibility. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: This utility model provides a technical solution:

[0029] See appendix Figure 1 As shown, the shoe support frame includes an expanded foot 1, with two expanded foot 1s respectively for the left and right feet, in order to solve the problem that traditional shoe supports cannot accurately fit the differences in the shape of the left and right feet;

[0030] Participation Figure 2 As shown, both extended footstocks 1 include a footstock last shell 11 and a footstock expansion unit 12. The footstock expansion unit 12 is disposed inside the footstock last shell 11. It should be noted that the footstock expansion unit 12 adopts the expansion method of a conventional shoe tree, so it is not described in detail. However, the end of the expansion drive shaft of the footstock expansion unit 12 is located at the tail of the footstock last shell 11 for detachable docking of the device.

[0031] In addition, as attached Figure 1 and appendix Figure 3 As shown, it also includes a main control lever 3:

[0032] The main control rod 3 is detachably connected to the foot expansion unit 12 so that the foot expansion unit 12 drives the foot last shell 11 to expand. In addition, through the detachable connection design between the main control rod 3 and the foot expansion unit 12, the shoe support can be flexibly assembled or disassembled according to actual needs.

[0033] Specifically, for the assembly and docking method of the main control rod 3, a polygonal groove 5 needs to be opened at the end of the drive shaft of the foot expansion unit 12, and a polygonal insertion part 6 adapted to the polygonal groove 5 is integrally formed at the end of the main control rod 3. Then, when in use, the polygonal insertion part 6 can be inserted into the polygonal groove 5 to detachably connect the main control rod 3 and the foot expansion unit 12.

[0034] In addition, as attached Figure 4 As shown, it also includes a heel support unit 4:

[0035] The heel support unit 4 includes a mounting ring 41 rotatably mounted on the outside of the main control rod 3. The mounting ring 41 has a continuous external thread on its outer side, and a heel support body 42 is threaded onto the mounting ring 41 to work in conjunction with the foot support unit 12. It can provide comprehensive support for the front and rear parts of the shoe as needed. In specific use, the entire device is placed inside the shoe body, and then the mounting ring 41 is rotated separately to drive the heel support body 42 to move, so as to adapt to the shoe body support of different sizes.

[0036] As a technical means, the end of the main control rod 3 away from the polygonal insertion part 6 is hook-shaped, which makes the whole unit easy to hook, store, and dry.

[0037] Furthermore, a polygonal grip 2 can be provided at the end of the mounting ring 41 to facilitate the rotation of the mounting ring 41 and thus expand the support for the heel.

[0038] Example 2: Based on Example 1, this application proposes another technical solution for the main control lever 3:

[0039] See appendix Figures 5-6 As shown, the main control rod 3 includes a hook part 31 and two extension rods 32. The ends of the two extension rods 32 are rotatably connected to the hook part 31, and the ends of the two extension rods 32 are also polygonal insertion parts 6. The two extension rods 32 are provided with heel expansion support units 4. With this design, while ensuring the basic characteristics of being detachable, it is convenient to store and dry a pair of shoes at the same time, avoiding subsequent storage work and ensuring more flexible use.

[0040] Furthermore, the design of rotating the two extension rods 32 allows the two shoes to be moved away from each other when expanding a single shoe body, thus effectively facilitating the rotation drive of the main control rod 3 when expanding a single shoe body.
