Description

Technical Field

[0001] The utility model relates to the technical field of shoes, in particular to a hands-free pulling auxiliary elastic member. Background Art

[0002] In the current field of footwear design and manufacturing, the heel design mainly follows traditional processing methods. This involves first precisely cutting the fabric according to the shoe design drawing, and then assembling the various components through processes such as gluing and pressing. This traditional processing method, with its efficient and stable production process, has dominated the footwear manufacturing industry, effectively meeting the high demand for footwear products in the market. However, from a user experience perspective, this traditional design of shoes has certain inconveniences when worn, especially in the processing of the heel.

[0003] Specifically, because traditional heel designs lack sufficient elasticity or support structures, users often need to insert their hands into the shoes and bend the heels to accommodate the foot shape. This action may not be difficult for most people, but it can pose a significant challenge for elderly people with limited mobility, people with physical disabilities, or young people who pursue a more convenient lifestyle. They may be troubled by a reluctance to bend frequently or lack sufficient hand strength, which affects the convenience and comfort of putting on shoes. Utility Model Content

[0004] In view of the deficiencies of the prior art, the present invention provides a hands-free pulling auxiliary elastic member, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a hands-free pulling auxiliary elastic part, including a main body, a plurality of deformation allowance holes are reserved at the heel of the main body, and the edge of the top of the main body is connected with a U-shaped edging, and a guide part is provided on the inner side of the top of the main body, and the guide part is an inclined surface from top to bottom.

[0006] Furthermore, both ends of the main body are connected to a wrapping portion, and the top of the wrapping portion has two raised portions and one recessed portion, and the two raised portions and one recessed portion together form an "S"-shaped curve wrapping structure.

[0007] Furthermore, a wing portion is connected between the two main bodies and the wrapping portion, and deformation allowance grooves are reserved between the main body and the wing portion, and between the wing portion and the wrapping portion.

[0008] Furthermore, the side wing portions and the wrapping portion are both convex arc-shaped structures with the top and bottom portions close to each other and the middle portions away from each other.

[0009] Furthermore, the main body, side wing parts and wrapping part are all components made of elastic materials and can undergo elastic deformation.

[0010] Furthermore, the inclination angle of the guide portion is 5 to 8 degrees.

[0011] Furthermore, among the shapes of several deformation allowance holes, the deformation allowance holes of the top and bottom layers are symmetrical trapezoidal structures, and the deformation allowance holes of the top layer are larger than those of the bottom layer, and the deformation allowance holes of the middle layer are diamond structures.

[0012] The utility model provides a hands-free pulling auxiliary elastic member. Compared with the prior art, it has the following features:

[0013] Beneficial effects:

[0014] This hands-free pull-assisted elastic member allows the user's heel to smoothly guide and adapt to the shape of the shoe during the donning process, automatically expanding and closing the heel with a simple step, eliminating the need to manually bend the heel. This innovative design not only effectively reduces the user's physical exertion when donning shoes, but also provides great convenience, especially for the elderly, those with physical disabilities, and those who seek convenience in life. It significantly improves the comfort and dignity of the shoe-donning process, while also avoiding the risk of lumbar injuries caused by frequent bending, thus having significant social benefits and practical value.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-7 The present invention provides a technical solution: a hands-free pulling auxiliary elastic member, consisting of a main body 1, two side wings 2 and two wrapping parts 4, wherein the main body 1, the two side wings 2 and the two wrapping parts 4 are all integrally formed by an injection molding process, and after molding, they are fixed to the outer side, inner side or middle layer of the heel of the shoe. The main body 1, the side wings 2 and the wrapping parts 4 are all components of elastic material and can undergo elastic deformation. When integrally formed, the top of the wrapping part 4 has two protrusions and one recessed part, and the two protrusions and one recessed part together form an "S"-shaped curve wrapping structure. Deformation allowance grooves 3 are reserved between the main body 1 and the side wings 2 and between the side wings 2 and the wrapping parts 4. The side wings 2 and the wrapping parts 4 are both convex arc-shaped structures with the top and bottom close to each other and the middle parts away from each other, which fit the shape of the human foot, not only achieving a more flexible wrapping process and making it more comfortable to wear, but also laying the foundation for the hands-free pulling function of the shoe.

[0025] In addition, a plurality of deformation allowance holes 11 are reserved at the heel of the main body 1. The deformation allowance holes 11 of the uppermost and lowermost layers are symmetrical trapezoidal structures, and the deformation allowance holes 11 of the uppermost layer are larger than the deformation allowance holes 11 of the lowermost layer. The deformation allowance holes 11 of the middle layer are diamond-shaped structures, and the edge of the top of the main body 1 is connected with a U-shaped edging 12. A guide portion 13 is provided on the inner side of the top of the main body 1. The guide portion 13 is an inclined surface from top to bottom, and the inclination angle of the guide portion 13 is 5 to 8 degrees.

[0026] When the user puts on the shoes, the foot first extends into the interior of the shoe through the shoe opening, and then the user's heel steps on the guide portion 13 of the main body 1. The user presses down with a little force on the heel, and the main body 1 will be deformed, causing the several deformation allowance holes 11 to be deformed synchronously. Because the guide portion 13 is an inclined surface from top to bottom, when the heel continues to exert force, the heel will automatically enter the heel. At this time, the main body 1 and the several deformation allowance holes 11 will also synchronously return to their initial state. The user does not need to pull out the heel with his hands, which saves time and effort. The user does not need to bend over when putting on the shoes, which can protect the user's waist.
