Description

Technical Field

[0001] This utility model belongs to the field of shoe last technology, specifically relating to a shoe last for tall boots. Background Technology

[0002] Because of their high boot shafts and diverse styles (such as over-the-knee boots, mid-calf boots, and Dr. Martens boots), the requirements for the structural design, dimensional accuracy, and fit of the shoe last are far higher than those for ordinary footwear. A shoe last specifically designed for tall boots is a shoemaking tool tailored to the foot shape, boot shaft form, and wearing needs of tall boots, directly affecting the boot's fit, comfort, and appearance.

[0003] Currently available boot lasts are often of fixed sizes. Due to the differences in boot height, if the last is too short, it cannot effectively shape the boot. If the last is too long, the boot toe will be stretched excessively, exceeding the normal curvature of the shoe, resulting in an unnatural bulge or distortion at the boot toe, losing its original smooth lines. Furthermore, the edge of the boot opening will be pulled outward, causing the originally flat boot opening to turn outward, curl, or become irregularly deformed. It is impossible to adjust the height of the last according to the height of the boot.

[0004] Therefore, a special shoe last for tall boots was designed to overcome the aforementioned technical defects. Utility Model Content

[0017] This specific embodiment is a shoe last specifically for tall boots, and its structural schematic diagram is as follows: Figures 1-7 As shown, it includes multiple lasts 1 and last feet 2. The multiple lasts 1 are detachably connected. The lowest last 1 is fixedly connected to the last foot 2. All lasts 1 are annular hollow structures. The top surface of each last 1 is provided with a docking groove 13. An air supply component is provided in the docking groove 13 on the uppermost last 1. A docking ring 12 is fixedly connected to the bottom surface of each last 1. A sealing component is provided between the multiple lasts 1.

[0018] The outer surface shape of the boot body 1 and boot foot 2 can be limited according to the size and style of the boots.

[0019] like Figure 5 As shown, two positioning blocks 3 are fixedly connected to the bottom surface of the last 1, and two positioning grooves 4 are opened on the top surface of the last 1. The upper positioning block 3 is adapted to the lower positioning groove 4, and the side wall of the positioning block 3 is provided with an anti-detachment component.

[0020] The connection method of positioning block 3 and positioning groove 4 can serve as a positioning function to facilitate docking, and also facilitates the connection of through holes 10 between multiple lasts 1, so that the injected hot airflow can flow into the interior of multiple lasts 1.

[0021] like Figure 3 and Figure 7 As shown, the anti-detachment component includes a groove 5 formed in the side wall of the positioning block 3, a stop block 6 is provided in the groove 5, a spring 8 is fixedly connected between the stop block 6 and the side wall of the groove 5, a slot 7 adapted to the stop block 6 is formed in the side wall of the positioning groove 4, and a control component is provided in the side wall of the stop block 6. The bottom surface of the stop block 6 is inclined.

[0022] like Figure 7 As shown, the control component includes a pull rope 9 fixedly connected to the side wall of the stop block 6. A through hole 10 is provided on the side wall of the groove 5, which penetrates the last 1 and communicates with the docking groove 13. The other end of the pull rope 9 passes through the through hole 10 and is fixedly connected to a pull ring 11. The pull rope 9 can be made of steel wire, which is both tough and strong.

[0023] By setting the stop block 6 as an inclined structure, when the positioning block 3 is inserted into the positioning groove 4, no other operation is required, and the locking can be automatically completed by the force of the spring 8, which has high flexibility. When the last 1 needs to be disassembled, the stop block 6 can be disengaged from the slot 7 simply by pulling the pull ring 11. Thus, the disassembly operation is also very convenient and highly practical.

[0024] like Figure 5As shown, the air supply assembly includes multiple air inlets 17 formed on the side wall of the through hole 10. The air inlets 17 are connected to the inner cavity of the last body 1. The through hole 10 penetrates the bottom surface of the last body 1 and is located inside the docking ring 12. Several fins 18 are fixedly connected to the inner wall of the last body 1.

[0025] Specifically, the through hole 10 is divided into two sections. One section runs through the upper and lower surfaces of the last 1, and the other section runs through the groove 5, so that the two sections of the through hole 10 are connected. In addition to storing the pull rope 9, one section of the through hole 10 is also used to inject hot airflow and can be used as an airflow channel. The airflow can easily enter the inner cavity of the last 1 from the air inlet 17. The fins 18 can be made of metal, preferably iron, copper, aluminum, etc., which can retain heat and prolong the time of hot airflow inside the last 1.

[0026] like Figure 6 As shown, the sealing assembly includes a sealing cap 14 threaded into the uppermost mating groove 13, and a connector 15 fixedly connected to the top surface of the sealing cap 14. The sealing assembly adopts a threaded connection, which facilitates mating with the last 1, and being located at the uppermost side, it does not require frequent disassembly. In use, only the middle last 1 needs to be spliced ​​together.

[0027] like Figure 5 As shown, a sealing ring 16 is fixedly connected to the side wall of the mating ring 12. The sealing ring 16 is used to enhance the sealing performance when multiple lasts 1 are mated together, and to prevent air leakage and waste.

[0028] Working principle: First, select an appropriate last 1 according to the height of the boot, and insert the positioning block 3 on the upper last 1 into the positioning groove 4 on the lower last 1. At the same time, the inclined surface of the stop block 6 is forced to move into the groove 5, and the spring 8 is compressed. When the positioning block 3 is inserted into the appropriate position in the positioning groove 4, the force of the spring 8 causes the stop block 6 to pop out and insert into the slot 7, which is used to fix the two lasts 1. After multiple lasts 1 are inserted, the sealing cover 14 is screwed into the uppermost docking groove 13 and connected to the external hot air pipe through the connector 15. Hot air is injected into the docking groove 13 and enters the inner cavity of multiple lasts 1 in sequence through the through hole 10 and the air inlet 17. At the same time, the fins 18 can retain and conduct heat, so that the last 1 and the last foot 2 generate heat, which helps to shape the boot and improve its performance.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
