Description

Technical Field

[0001] This invention discloses a five-finger shoe last, belonging to the field of footwear production technology. Background Technology

[0002] A shoe last is a mold used in shoe production to support and shape the inside of a shoe.

[0003] Five-finger shoes are a new type of shoe. With the popularization of health concepts, five-finger shoes are becoming more and more popular. However, because existing five-finger shoes require the big toe to be separated, and because people wear ordinary shoes all year round, their toes are usually in a closed state. When wearing five-finger shoes, the thickness of the shoe upper will cause the toes to be separated by a large distance. This means that there is no transitional adaptation period when wearing five-finger shoes. The existing shoe last cannot be adjusted to compress and thin the shoe upper between the big toe.

[0004] A new solution is proposed to enable a smooth transition for first-time wearers after the five-finger shoes are molded. Summary of the Invention

[0005] The purpose of this invention is to provide a five-finger shoe last in order to solve the above-mentioned problems.

[0006] The present invention achieves the above objective through the following technical solution: a five-finger shoe last, comprising:

[0007] The shoe last, the main body of the shoe last, is hollow inside;

[0008] The thumb piece is movably installed on the last body. Five thumb pieces are provided and are made to mimic the shape of the human big toe.

[0009] A control device is fixedly installed inside the last body, and the control device is used to control the distance between the thumb pieces;

[0010] A hot-pressing component is fixedly installed on the thumb component, and the hot-pressing component is used to convert electrical energy into heat energy;

[0011] The hot-pressing component is located on the side adjacent to the thumb component.

[0012] Preferably, the control device includes a rotating plate, a pressure component, and a power component. The rotating plate is rotatably connected to the inner wall of the last and is fixedly connected to a thumb component at one end away from the last. The pressure component is slidably installed inside the last and abuts against the rotating plate for transmission. The power component is installed inside the last and is connected to the pressure component for transmission.

[0013] Preferably, the rotating plate has a pressure groove and a movable groove that are interconnected. The movable groove is arc-shaped and concentric with the rotation point of the rotating plate. The pressure groove extends from the movable groove to the inside of the thumb member. The pressure member is provided with a protrusion that moves within the pressure groove and the movable groove.

[0014] Preferably, two pressure rollers are fitted on the protrusion, and the two pressure rollers abut against the two sides of the pressure groove respectively.

[0015] Preferably, there is a gap between the two pressure rollers, and they do not drive each other.

[0016] Preferably, the power component is a cylinder, the pressure component slides inside the power component, and the pressure component and the power component are sealed together. A conduit is provided at the end of the power component away from the pressure component. The conduit extends along the last to the corresponding ankle position and exits the last.

[0017] Preferably, the last is provided with a contact piece at the corresponding ankle position, and the contact piece is electrically connected to the hot press component.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: When using this product, the thumb piece on the last is inserted into the corresponding toe position of the shoe. Then, the hot pressing component is energized to heat up. The thumb piece is then pushed by the control device to bring the thumb pieces closer together, so that the thumb piece heats and presses the fabric between the toes. The heat pressing reduces the gap between the toes of the shoe fabric, thereby reducing the overall thickness of the fabric. This prevents the toes from experiencing severe discomfort due to excessive fabric thickness between the toes when wearing five-finger shoes, making them more comfortable to wear. Furthermore, the heat-pressing deformation process, which has relatively poor stability, allows the shoe to slowly return to its original position during daily use, gradually increasing the distance between the toes. This allows the wearer to become more accustomed to wearing any five-finger shoe after a period of time. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In this description, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a five-finger shoe last includes:

[0026] The last 1 comprises a thumb piece 2 movably mounted on the last 1, a control device fixedly mounted inside the last 1, and a hot-pressing component fixedly mounted on the thumb piece 2. The last 1 is hollow inside. Five thumb pieces 2 are provided and are made to mimic the shape of a human big toe. The control device is used to control the distance between the thumb pieces 2. The hot-pressing component is used to convert electrical energy into heat energy and is located on the side adjacent to the thumb piece 2. The control device includes a rotating plate 32, a pressure component 33, and a power component 31. The rotating plate 32 is rotatably connected to the inner wall of the last 1 and is fixedly connected to the thumb piece 2 at the end away from the last 1. The pressure component 33 is slidably mounted inside the last 1 and abuts against the rotating plate 32 for transmission. The power component 31 is mounted inside the last 1 and is connected to the pressure component 33 for transmission.

[0027] This product is suitable for producing five-finger shoes. First, the shoe last 1 is placed inside the shoe. Then, with the control device off, the position of the thumb piece 2 is adjusted so that it accurately inserts into the corresponding toe hole. Electricity is then supplied to the heating element, causing it to heat up. The power element 31 is then activated, pushing the pressure element 33, which in turn pushes the rotating plate 32. The rotating plate 32 moves the thumb pieces 2 closer together, allowing them to press against the fabric between the thumb pieces 2, thus reducing the gaps between the fibers of the fabric. The reduction in size leads to a decrease in the thickness of the fabric. Furthermore, the contouring of the thumb piece 2 causes the fabric surface to form the shape of a thumb, ensuring that the shape of the toes on the five-finger shoe matches the shape of human toes. This reduces the feeling of foreign objects when wearing the shoes, making them more comfortable for users initially. Additionally, through heat pressing, the heat-pressed points gradually reset as the user wears the shoes. The reset fabric then pushes the toes apart, resulting in a situation where there is no strong feeling of foreign objects when wearing normal five-finger shoes.

[0028] The rotating plate 32 has a pressure groove 321 and a movable groove 322 that are interconnected. The movable groove 322 is arc-shaped and concentric with the rotation point of the rotating plate 32. The pressure groove 321 extends from the movable groove 322 into the interior of the thumb piece 2. The pressure piece 33 has a protrusion 331 that moves within the pressure groove 321 and the movable groove 322. The movable groove 322 allows the protrusion 331 to move left and right when it is within the groove, thus allowing the thumb piece 2 to adjust its position freely when inserted into the shoe to the corresponding thumb position. The thumb piece 2 is better inserted into the thumb position of the shoe, and then the power piece 31 pushes the pressure piece 33, so that the pressure piece 33 slides along the movable groove 322 to the pressure groove 321. When the pressure piece 33 moves from the sliding groove to the pressure groove 321, the pressure piece 33 abuts against one side wall of the movable groove 322, so that the pressure groove 321 pushes the rotating piece 32 to rotate. The rotating piece 32 drives the thumb piece 2 to press against the fabric, thereby forming a heat-pressed indentation on the surface of the fabric. This reduces the gap between the toes when the toes are inserted into the shoe, so that the foot does not feel a foreign object.

[0029] Two pressure rollers 332 are fitted on the protrusion 331. The two pressure rollers 332 abut against the two sides of the pressure groove 321 respectively. There is a gap between the two pressure rollers 332 and they do not drive each other. When the two pressure rollers 332 abut against the two sides of the pressure groove 321 respectively, they can independently push the side wall of the pressure groove 321, avoiding the situation of jamming when pushing. In addition, the rotation of the pressure rollers 332 can effectively reduce the friction, making it easier for the pressure component 33 to push the rotating plate 32, and also avoiding wear.

[0030] The power component 31 is set with a cylinder body, and the pressure component 33 slides inside the power component 31. The pressure component 33 and the power component 31 are sealed together. A conduit 34 is set at the end of the power component 31 away from the pressure component 33. The conduit 34 extends along the last 1 to the corresponding ankle position and exits the last 1. The control of the last 1 is transmitted to the outside through the conduit 34. By pumping hydraulic oil or air into the last 1, the power component 31 drives the pressure component 33 to move, thereby achieving the effect of the power component 31 pushing the pressure component 33. It is directly controlled from the outside, making the control more convenient. If hydraulic oil is used to control the power component 31, valves need to be set at the inlet and outlet of the conduit 34 to prevent the hydraulic oil from leaking when moving the shoe last.

[0031] The last 1 is provided with a contact piece 4 at the corresponding ankle. The contact piece 4 is electrically connected to the hot press component, and electrical energy is transferred through the contact piece 4, making it more convenient when transportation is required.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
