Description

Technical Field

[0001] The utility model belongs to the technical field of shoe materials, and particularly relates to a quick-wearing shoe heel structure. Background Art

[0002] With the continuous development of society, the types and styles of shoes have become more and more diverse. Different styles of shoes have different wearing effects. When wearing many existing shoes, it is necessary to bend down or squat down to expand the wearing opening of the shoe upper to facilitate putting the foot into the shoe. After that, it is necessary to tighten the shoe upper through shoelaces or elastic bands, so the process of putting on shoes is time-consuming. Another way to put on shoes is to push the foot into the shoe by stepping on the heel, but this method causes the heel to deform due to repeated extrusion, thus affecting the service life of the shoes.

[0003] The Chinese utility model patent with the publication number CN221179536U discloses a quick-wearing shoe, which specifically relates to the field of shoes, including a shoe sole and a shoe upper connected to the shoe sole. A heel is arranged at the rear end of the shoe upper, and a support component is arranged on the outer surface of the heel at the rear end of the shoe sole to support and rebound the heel through the support component; the top surface of the heel is inclined downward, and a fixing component is embedded in the heel to shape the opening of the heel, facilitating putting on the shoes faster. In the utility model, the support component is adopted to support at the heel. After the heel is stepped on and released, the support component will reset the heel to avoid the deformation of the heel under pressure. At the same time, the top surface of the heel opening is designed with an inclined surface downward, which is convenient for directly inserting the foot into the shoe. And a fixing piece is installed inside the heel opening to maintain the shape of the opening and avoid the deformation of the heel opening, affecting the wearing efficiency. However, pushing the foot into the shoe by stepping on the heel for a long time causes elastic fatigue of the support component, resulting in the aging and collapse of the shoe heel.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1:

[0030] As Figures 1 - 10As shown in the figure, a fast - wearing shoe heel structure provided by the utility model, the shoe heel structure 1 includes a main support keel 2, a main support component 3 and a secondary support component 4. A secondary support keel 10 is wrapped inside the main support keel 2.

The secondary support component 4 is arranged outside the horn - shaped part 5, and the main support component 3 is arranged outside the wrapping part 6. A clamping protection bag 7 is arranged on the inner side of the main support keel 2 at the connection between the horn - shaped part 5 and the wrapping part 6. Both the main support component 3 and the secondary support component 4 are fixed on the main support keel 2 by means of sewing with a needle and thread. Glue is provided on the joint surface between the main support component 3 and the secondary support component 4 and the main support keel 2. The connection part 8 between the clamping protection bag 7 and the horn - shaped part 5 is smoothly transitioned in the shape of the horn - shaped part 5. The clamping protection bag 7 is bent in a U - shape and a foot tendon accommodation groove 9 is formed in the middle section. The inside of the clamping protection bag 7 is any one of an air bag, a cotton bag and a down bag. The materials of the main support component 3 and the secondary support component 4 are PU material / fabric / TPEE material. The material of the secondary support keel 10 is TPEE material.

[0031] Through the above - mentioned technical solution, the shoe heel structure 1 of the utility model includes a main support keel 2, a main support component 3 and a secondary support component 4. The upper end of the main support keel 2 is turned outwards to form a horn - shaped part 5 in a semi - horn shape, and the lower end of the main support keel 2 is a wrapping part 6. A secondary support component 4 for enhancing the elastic support force is arranged outside the horn - shaped part 5, and a main support component 3 for enhancing the elastic support force is arranged on the wrapping part 6. When quickly putting on shoes, the heel is first inserted into the shoe body by stepping on the shoe heel structure 1. In this process, the shoe heel structure 1 is first squeezed and deformed, and then through the elastic action of the main support component 3 and the secondary support component 4, the shoe heel structure 1 returns to its original state, preventing the shoe heel structure 1 from collapsing and improving the service life of the shoes.

[0032] The horn - shaped part 5 of the main support keel 2 provides an inclined plane, enabling the heel to slide more smoothly into the shoe body, reducing the degree of deformation of the shoe heel structure 1 when being stepped on. A clamping protection bag 7 is also arranged on the main support keel 2. The connection between the clamping protection bag 7 and the horn - shaped part 5 is smoothly transitioned through the connection part 8, further improving the smoothness of the heel sliding into the shoe body, reducing the degree of deformation of the shoe heel structure 1 when being stepped on, preventing the shoe heel structure 1 from collapsing under long - term repeated stepping, and improving the service life of the shoes.

[0033] A secondary support keel 10 is wrapped inside the main support keel 2. The secondary support keel 10 is fixed to the main support keel 2 as a whole by means of gluing, improving the elastic support force of the main support keel 2.

[0034] The horn part 5 of the main support keel 2 provides an inclined surface, enabling the heel to slide more smoothly into the shoe body, reducing the degree of deformation of the shoe heel structure 1 when stepped on, and a clamping protective sac 7 is also arranged on the main support keel 2. The connection between the clamping protective sac 7 and the horn part 5 has a smooth transition through the connecting part 8, further improving the smoothness of the heel sliding into the shoe body, reducing the degree of deformation of the shoe heel structure 1 when stepped on, preventing the shoe heel structure 1 from collapsing under long-term repeated stepping, and improving the service life of the shoe.

[0035] Embodiment 2:

[0036] As Figures 1 - 10 shown, the shoe heel structure 1 of the present utility model includes a main support keel 2, a main support component 3 and a sub-support component 4. The main support keel 2 is integrally U-shaped to enhance the wrapping, stability and comfort of the shoe heel structure 1. A sub-support keel 10 is wrapped inside the main support keel 2, and the sub-support keel 10 is fixed to the main support keel 2 as a whole by gluing to improve the elastic support force of the main support keel 2. The upper end of the main support keel 2 turns outwards to form a horn part 5 in the shape of a semi-horn. When the user wears the shoes, the front part of the foot is inserted into the shoe body. At this time, the heel is located at the position of the horn part 5. By stepping on the horn part 5, under the action of the inclined surface of the horn part 5, the heel falls into the shoe body, and the shoe wearing process is quickly completed. The lower end of the main support keel 2 is designed with a wrapping part 6, and the wrapping part 6 is used to wrap the heel, and its shape is similar to that of the heel, so that the shoes are fixed on the user's feet.

[0037] On the outer side of the horn part 5, a sub-support component 4 is installed. The function of the sub-support component 4 is to enhance the elastic support force of the shoe heel structure 1 and ensure that the shoe heel structure 1 still has a restoring force after long-term repeated stepping. When quickly wearing the shoes, the user starts to insert the heel into the shoe body by stepping on the shoe heel structure 1. During this process, the horn part 5 is subjected to a strong extrusion force and will sink to a large extent. The long-term repeated large-degree sinking will cause elastic fatigue of the horn part 5 and cause the horn part 5 to not be able to recover. By installing the sub-support component 4 on the outer side of the horn part 5, the elastic support force of the horn part 5 can be improved, preventing the horn part 5 from being deformed too much under pressure, and improving the overall service life of the shoes. The combination of the sub-support component 4 and the horn part 5 provides additional stability and reduces the deformation phenomenon of the shoe heel part. The durability of the shoes is improved, and the comfort of the user when wearing is also increased.

[0038] To further improve the elastic support force of the shoe heel structure 1, a main support component 3 is installed on the outer side of the wrapping part 6. The main support component 3 is used to prevent the wrapping part 6 from deforming due to repeated use, thereby extending the service life of the shoes. When the user starts to insert the heel into the shoe body by stepping on the shoe heel structure 1, not only the horn part 5 but also the wrapping part 6 is subjected to a strong squeezing force. If the wrapping part 6 undergoes irreversible collapse, the collapse will cause protrusions to appear on the wrapping part 6, and these protrusions will press against the heel, which greatly affects the usability. By installing the main support component 3 on the outer side of the wrapping part 6, the elastic support force of the wrapping part 6 is improved, and the collapse of the wrapping part 6 is prevented. The combination of the main support component 3 and the wrapping part 6 ensures the firmness and comfort of the shoe heel, making the wearing experience more comfortable.

[0039] On the inner side of the main support keel 2, a clamping protective sac 7 is also provided at the connection between the horn part 5 and the wrapping part 6. The function of the clamping protective sac 7 is to provide additional wrapping and protection for the heel part of the shoe, prevent structural relaxation or displacement during wearing, and improve the comfort at the same time.

[0040] Embodiment Three:

[0041] As Figures 1 - 10 shown, the main support component 3 and the sub-support component 4 of the present utility model are fixed on the main support keel 2 by means of sewing with a needle and thread. This method firmly attaches these two components to the surface of the main support keel 2 through the sewing thread. This sewing process can effectively increase the connection strength between the main support component 3 and the sub-support component 4 and the main support keel 2, so that they will not fall off or become loose due to the action of external forces during use. In addition, in order to further improve the bonding firmness between the main support component 3 and the sub-support component 4 and the main support keel 2, glue is applied on their mating surfaces, so that the main support component 3 and the sub-support component 4 form an integral structure with the main support keel 2, improving the elastic support force of the shoe heel structure 1. Through the fixed method combining sewing with needle and thread and glue adhesion, the main support component 3 and the sub-support component 4 can form a tight integral structure with the main support keel 2. Such a combination not only increases the firmness of the structure but also improves the elastic support force. The fixing effect of the main support component 3 and the sub-support component 4 on the main support keel 2 enables the shoe heel structure 1 to better maintain its original shape and function when bearing the foot force, and avoids deformation or collapse of the shoe heel structure 1 due to repeated extrusion or long-term use.

[0042] Embodiment Four:

[0043] As Figures 1 - 10As shown, the connection between the clamping protective sac 7 and the horn part 5 of the present utility model presents a smooth transition with the same shape as the horn part 5. This smooth transition design makes the interface between the clamping protective sac 7 and the horn part 5 have no obvious protrusions or depressions, thereby improving the smoothness of the heel slipping into the shoe body during the shoe wearing process. When the heel passes through this smooth transition area, it will not be blocked or stuck, ensuring that the shoe wearing action is smooth and natural, and further enhancing the user's wearing experience.

[0044] The clamping protective sac 7 of the present utility model is bent in a U shape and forms a tendon accommodating groove in the middle section. The design of this tendon accommodating groove is used to cooperate with the protruding tendon part of the heel. Through this structure, the tendon accommodating groove can adapt to the natural contour of the heel, making the shoe wearing process more comfortable and further enhancing the user's wearing experience.

[0045] The internal filling material of the clamping protective sac 7 of the present utility model can be any one of an air sac, a cotton sac or a down sac. Selecting an air sac, a cotton sac or a down sac as the internal filling material aims to significantly improve the comfort of wearing the shoes. The air sac provides an adjustable gas pressure, enabling the shoe heel area to adapt to the shape and movement state of the foot, thereby providing a good buffering effect and comfort. The cotton sac provides a comfortable wrapping feeling and a certain supporting force with its soft characteristics, ensuring effective relief and protection for the shoe heel during wearing. The down sac provides high-quality comfort and lightness for the shoe heel area with its excellent warmth retention and light characteristics. These different filling materials can provide different comfort experiences for users during the shoe wearing process and effectively improve the overall comfort of the shoes.

[0046] Embodiment Five:

[0047] As Figures 1 - 10 shown, the materials of the main support component 3 and the auxiliary support component 4 of the present invention are any one of PU material, fabric or TPEE material. The use of these materials has a significant impact on the performance and comfort of the shoe heel structure 1.

[0048] PU material, that is, polyurethane material, is widely used in the shoe heel structure 1 due to its excellent elasticity and durability. The PU material has excellent elastic recovery ability, enabling the main support component 3 and the auxiliary support component 4 to quickly return to their original shapes after being subjected to foot pressure, preventing the shoe heel structure 1 from collapsing and increasing the service life of the shoes. The PU material also has good abrasion resistance and anti-aging properties, and can maintain its stability and function during multiple uses, reducing the possibility of deformation and damage.

[0049] Fabric, as another alternative material, has good softness and breathability. The fabric material can effectively absorb and discharge sweat, reducing the discomfort of the feet caused by long-term wearing. At the same time, the elasticity and flexibility of the fabric enable the shoe heel structure 1 to better adapt to the movement and changes of the feet, providing appropriate support and comfort.

[0050] The TPEE material, that is, thermoplastic elastomer, combines the elasticity of rubber and the durability of plastic, improving the elastic support force of the main support component 3 and the secondary support component 4, preventing the shoe heel structure 1 from collapsing, and increasing the service life of the shoes. The TPEE material has excellent elasticity and strength, and can provide good support and comfort when bearing the pressure of the feet.

[0051] The main support keel 2 of the present invention encloses a secondary support keel 10 inside to improve the elastic support force of the main support keel 2. The material of the secondary support keel 10 is TPEE material. The TPEE material has very stable physical properties, is not easy to deform and has elasticity. The secondary support keel 10 is fixed inside the main keel by gluing to improve the elastic support force of the main support keel 2.

[0052] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0053] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of this should be covered within the scope of the claims of this as long as they do not depart from the spirit and scope of the technical solution of this.
