Description

Technical Field

[0001] The present invention belongs to the technical field of footwear, and particularly relates to a sock-free hand-free shoe based on innovative structural design and its manufacturing process, which is especially suitable for scenarios with convenient wearing and taking off requirements. Background Art

[0002] During the use of traditional footwear products, the wearing and taking off process usually requires the user to use their hands to assist in stretching the shoe opening and bend down to insert the foot into the shoe. This operation method poses significant usage barriers for the elderly, pregnant women, people with limb disabilities or limited mobility, and users in fast-paced work scenarios. Although some footwear products claiming to have convenient wearing and taking off functions have been launched in the current market, in actual applications, their wearing and taking off processes still cannot achieve a truly "hand-free" operation, and there is still a large room for improvement in terms of wearing comfort, anti-slip performance, and cleaning convenience. Therefore, it is of great practical significance to develop a new type of footwear product that can effectively solve the above problems. Summary of the Invention Object of the Invention

[0003] The present invention aims to achieve the function of quickly wearing and taking off without hand assistance in a standing state through innovative designs of core components such as the heel counter structure and the connection method between the sock and the sole. At the same time, by optimizing the elastic structure of the sock, the anti-slip design of the sole, and the cleaning characteristics, the comprehensive performance of the footwear product is comprehensively improved to meet the diverse needs of different user groups.

[0004] The sock-free hand-free shoe is composed of a low-waist elastic sock and a foamed lightweight sole. Among them, the sock is provided with an inlet, a heel part, and a cavity part. The heel part adopts a pocket-shaped double-layer structure and is internally provided with an easy-to-wear and take-off heel counter, which includes a guiding part for guiding the heel to slide into the shoe and an arc part for accommodating the heel. The inner and outer waists of the cavity part and the connection between the side and bottom of the shoe head extend out an eaves-shaped protruding strip, which is connected to the outer bottom edge of the double-layer structure of the heel part to form a closed-loop structure and is fixedly connected to the edge of the midsole material through a lockstitch process.

[0005] Elastic sock: It is made by an elastic knitting process to ensure that the sock can closely fit the foot, improving the wrapping and comfort of wearing.

[0006] Protruding strip structure: The protruding strip is designed to have a width suitable for the lockstitch process. Through firm stitching with the edge of the midsole material and the fixation of the midsole material and the sole, the connection stability between the sock and the sole is ensured.

[0007] Optimization of the heel counter: In the smooth transition area between the guiding part and the arc part, a clamping foot structure that at least partially protrudes from the shoe head in the side view direction is formed. This structure can effectively prevent the heel from slipping out during the wearing state and enhance the wearing stability of the shoe.

[0008] Sole functional design: A stepping part is provided at the heel part of the sole, facilitating the user to perform the shoe removal operation by applying pressure with the other foot; the bottom surface of the sole adopts an anti-slip texture design or adheres anti-slip rubber sheets to ensure walking safety.

[0009] Buffering design: Memory cotton, latex and other buffering materials are provided on the upper surface of the midsole material, directly acting on the sole through the sockliner, providing a comfortable foot feeling while simplifying the structure of the insole.

[0010] Elastic control structure: A confinement structure is provided in the cavity part of the sockliner. By sewing elastic bands or using special knitting techniques, the elastic expansion range of the sockliner is restricted, avoiding the phenomenon of the shoe not fitting well during wearing.

[0011] The sockliner-free hands-free shoe supports machine washing, facilitating daily cleaning and maintenance. Beneficial effects

[0012] 1. Convenient wearing and taking off: Through the structural cooperation of the heel counter guiding part and the arc part, combined with the self-adaptive wrapping characteristics of the elastic sockliner, rapid wearing and taking off without hand assistance and without bending down in a standing state are realized, significantly improving the convenience of use.

[0013] 2. Comfortable fitting: The synergistic effect of the elastic sockliner, the cavity part confinement structure and the midsole buffering material enables the shoe to closely fit the foot contour and provide a good shock absorption and buffering effect, effectively improving the wearing comfort.

[0014] 3. Stable anti-slip: The heel counter clamping part design prevents the heel from slipping out during walking. Combined with the anti-slip structure of the sole, a stable walking experience is provided for the user, reducing the risk of slipping.

[0015] 4. Cleaning convenience: The machine-washable feature simplifies the cleaning process of the shoe, saving the user's time and energy costs.

[0016] 5. Structure optimization: The traditional insole design is omitted, and the midsole buffering material directly acts on the sole, simplifying the product structure and reducing the production cost; at the same time, the lock-sewing connection method between the protruding strip and the midsole material ensures the stability of the overall structure of the shoe body.

Specific Embodiments

[0021] The following is combined with Figures 1-3 , to introduce the specific embodiments. (I) Manufacturing Method of Sock Sleeve Hands-Free Shoes 1. Sock Sleeve Manufacturing

[0022] Fabric Processing: Select elastic yarns to knit the sock sleeve. Reserve the foot entry opening, heel part, cavity part, and eaves-shaped protruding strip according to the design dimensions.

[0023] Heel Part Assembly: Knit the heel part into a pocket-shaped double-layer structure, and accurately install the easy-to-put-on-and-take-off heel counter inside the double-layer structure to ensure that the guiding part, arc part, and foot clamping part are in accurate positions and the surface of the heel part has a smooth transition.

[0024] Protruding Strip Connection: Make the pre-knit eaves-shaped protruding strip at the inner and outer waists of the cavity part and the connection between the side and bottom of the shoe tip form a closed-loop structure with the outer bottom edge of the double-layer structure of the heel part.

[0025] Elastic Control: Construct a confinement structure at a suitable position in the cavity part by sewing elastic bands or using special knitting techniques to limit the elastic expansion range of the sock sleeve. 2. Sole Manufacturing

[0026] Molding Process: Select foamed lightweight materials such as EVA, and injection mold the sole through a mold, reserving the stepping part structure at the heel position.

[0027] Anti-Slip Treatment: Design anti-slip textures or paste anti-slip rubber sheets in the key contact areas on the bottom surface of the sole to form an anti-slip structure.

[0028] Cushioning Setting: Paste or sew cushioning materials such as memory foam and latex on the upper surface of the midsole material to complete the sole manufacturing. 3. Upper Assembly

[0029] Adopt a lockstitch process to firmly stitch the closed-loop structure of the sock sleeve to the edge of the midsole material to ensure that the sock sleeve and the midsole material are tightly combined as a whole. 4. Shoe Body Assembly
