Description

TECHNICAL FIELD

[0001] The utility model relates to shoe technology field, concretely relates to a kind of elastic shoe sole and the shoe of application this shoe sole. BACKGROUND

[0002] In today's footwear manufacturing field, the performance of the sole plays a crucial role in the overall comfort and functionality of the shoe. As consumers' demands for wearing experience continue to rise, the elasticity of the sole has become a focus for many shoe manufacturers and researchers.

[0003] Traditional soles are usually made of a single material and are formed as a whole, which has limited elasticity and cannot meet the needs of human body for cushioning and rebound performance of the sole in various scenarios such as long-distance walking and sports. In recent years, in order to improve the elasticity of the sole, researchers have made many innovative attempts.

[0004] Patent application No. CN202322346070.X discloses an elastic sole. It achieves the enhancement of the elasticity of the sole by setting a slot at the rear end of the sole and placing a spring element in the slot. This design has a certain pioneering nature. The slot breaks the original rigid structure of the sole, giving the sole stronger deformation ability, so that the sole can more flexibly adapt to different ground conditions and human movements when under stress. The spring element is placed in the slot and bears the responsibility of supporting and stabilizing the overall structure of the sole, so that the sole maintains stability during repeated deformation and avoids excessive deformation that may cause damage to the sole or exacerbate the discomfort of wearing.

[0005] However, after a thorough analysis of the design, it is not difficult to find its limitations. Since the spring element is strictly adapted to the shape and size of the slot, the close fit of the two not only ensures structural stability but also raises new problems. On the one hand, the spring element, due to its relatively fixed shape and rigidity, inevitably restricts the free deformation of the slot when the sole is deformed under stress. The slot cannot fully expand and compress as expected, which limits the space for improving the elasticity of the sole. The elasticity of the sole relies more on the elasticity of the spring element itself rather than the combined performance of the slot and the spring element. On the other hand, this close-fitting structure, due to frequent friction and compression between the spring element and the slot, is prone to component wear, shortening the service life of the sole, and may also cause local stress concentration in the sole, further weakening the elasticity of the sole and affecting the wearing experience. In summary, although the existing technology has made an important step in improving the elasticity of the sole, there are still many problems to be solved, and a new sole elasticity optimization scheme is urgently needed.

[0027] Fig. 2 It is a structural schematic view of the utility model.

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present utility model.

[0030] The following references are made to Figs. 1-2 The present utility model is described as follows:

[0031] Embodiment: The elastic shoe sole relates to a core component, which comprises a shoe sole body 2, a slot 1, a bottom support 3, a connecting strip 4, and two support columns, i.e., a first support column 5 and a second support column 6.

[0032] The shoe sole body 2 is a basic load-bearing part of the whole shoe sole structure, and the bottom surface of the heel of the shoe sole body 2 is provided with the slot 1, which is arranged through the left side, the right side, the back side and the lower side of the shoe sole body 2. This all-around through design is of great significance. From the perspective of mechanics, when the shoe sole is subjected to vertical pressure or friction force in different directions from human walking or movement, the area occupied by the slot 1 can first produce deformation, and due to its multi-directional through characteristics, the deformation can be expanded synchronously or sequentially in multiple dimensions, breaking the rigid limitation of the traditional single-material integral forming of the shoe sole and laying a foundation for the overall elasticity improvement of the shoe sole.

[0033] The bottom support 3 is located at the lower side of the heel of the shoe sole body 2, and it plays a key role in the whole elastic system. The upper side of the bottom support 3 is provided with support columns connected with the rear end of the shoe sole body 2. The number of the support columns here is two, which are the first support column 5 and the second support column 6, and the first support column 5 is in front and the second support column 6 is at the back. The front and back layout of the support columns, combined with the relative position relationship between the bottom support 3 and the shoe sole body 2, constructs a unique mechanical support architecture. On the one hand, the support columns provide vertical support force for the shoe sole body 2, which ensures that the shoe sole will not collapse excessively when the shoe sole bears weight, and maintains the basic shape of the shoe sole and the wearing stability; on the other hand, they separate the shoe sole body 2 and the bottom support 3 in the vertical direction, and together with the bottom support 3 form a first deformation cavity 7. The first deformation cavity 7 is an important space for the elastic buffering of the shoe sole, and in the process of stress, the air in the cavity can be compressed and released, cooperating with the deformation of the shoe sole body 2 and other components, to absorb and disperse the impact force on the sole, and improve the rebound performance of the shoe sole.

[0034] The front end of the bottom support 3 is connected with the sole body 2 through the connecting strip 4. From the perspective of structural integrity, the connecting strip 4 cooperates with the support column to stably attach the bottom support 3 under the sole body 2, avoiding displacement and falling of the bottom support 3 during use. Further observation shows that the lower end of the first support column 5 is connected with the rear end of the connecting strip 4, and this connection mode skillfully utilizes the geometric relationship among the three to enclose the second deformation cavity 8 among the sole body 2, the first support column 5 and the connecting strip 4. The existence of the second deformation cavity 8 further enriches the elastic performance level of the sole, and cooperates with the first deformation cavity 7 to play a respective buffering and deformation role at different stress stages and stress positions.

[0035] In particular, the bottom support 3 is connected with the sole body 2 only through the connecting strip 4 and the support column, in a point contact connection state. This connection mode minimizes the restriction of the bottom support 3 on the deformation of the sole body 2, especially the slot 1. Unlike the similar components in the traditional sole design which are closely attached to each other and restrict each other, the slot 1 here is almost not additionally restricted around during the stress deformation of the sole, and can freely expand and compress according to the size and direction of external force, fully mobilizes the elastic potential of the sole material itself, and comprehensively improves the elastic ability of the sole body 2, providing a more superior buffering and rebound experience for the wearer, effectively reducing foot fatigue and improving the overall comfort and functionality of the shoe, whether for long walking or high-intensity sports scenarios.

[0036] The sole body 2 includes an upper sole 21 and a lower sole 22. The upper sole 21, as the part directly contacting the foot, adopts a relatively soft material. This feature enables the wearer to feel a more comfortable touch during walking or exercising, and better fits the foot contour, effectively disperses the foot pressure, and avoids excessive local pressure causing discomfort. Moreover, the relatively soft material can quickly respond when slightly stressed, providing preliminary buffering for the overall elastic feedback of the sole.

[0037] The lower sole 22 is arranged on the lower side of the upper sole 21, and the hardness of the lower sole 22 is greater than that of the upper sole 21. This hardness difference design has a clear functional consideration. The lower sole 22, with its higher hardness, undertakes the main supporting task, especially when dealing with large external force impact, it can maintain the stability of the sole structure and prevent excessive deformation of the sole. For example, when the wearer performs jumping, running or other intense exercise, the foot instantaneously applies a large pressure to the sole, and the lower sole 22 can resist excessive deformation by its rigidity, ensuring the stability of the overall sole structure and avoiding the risk of foot injury caused by sole collapse. At the same time, as the direct carrier of the slot 1, the relatively stable structural characteristics of the lower sole 22 provide a reliable basic framework for the slot 1 during multidirectional deformation, ensuring that the slot 1 can accurately perform the elastic deformation function as designed.

[0038] The lower shoe sole 22 and the insole 3 are made of plastic. The plastic material has many advantages to meet the needs of the shoe sole. On the one hand, it has a certain flexibility and can deform moderately under stress, providing elastic power for the shoe sole. On the other hand, its good wear resistance ensures that the shoe sole is not easily worn out during long-time friction with the ground, maintaining the service life of the shoe sole. Moreover, the plastic material is relatively light, which helps to reduce the overall weight of the shoes and improve the feeling of lightness when wearing.

[0039] The connecting strips 4 and the support columns are connected with the lower shoe sole 22, and this connection mode strengthens the overall integrity of the shoe sole structure. The connecting strips 4 connect the front end of the insole 3 with the lower shoe sole 22, ensuring that the insole 3 always maintains a relative fixed positional relationship with the shoe sole during dynamic stress of the shoe sole, preventing loosening due to external force pulling and twisting. The support columns are also connected with the lower shoe sole 22, and they are precisely distributed in the heel part of the lower shoe sole 22, cooperating with the insole 3 to not only build a stable mechanical support system to provide vertical support force for the shoe sole, but also participate in enclosing the key first deformation cavity 7 and the second deformation cavity 8.

[0040] The lower shoe sole 22, the connecting strips, the first support columns 5, and the insole 3 are integrally provided. This integrated design greatly optimizes the performance of the shoe sole. From the perspective of production and manufacturing, it reduces the assembly link of parts, reduces production cost and process complexity, and improves production efficiency; from the perspective of structural mechanics, integral molding eliminates the connection gaps and weak links between parts, making the force transmission between the parts of the shoe sole more smooth and efficient. When the shoe sole is stressed, the parts deform cooperatively and do not produce stress concentration or energy loss due to loose connection, ensuring that the elastic mechanism of the shoe sole operates stably, continuously provides reliable cushioning and rebound effect for the wearer, meets the diversified sports and daily walking needs, and improves the wearing experience of the shoes in all directions.

[0041] The design of the second support column 6 has a unique and ingenious feature. Its upper and lower ends are connected with the lower shoe sole 22 and the insole 3 by hinged connection, and this connection form brings many advantages to the improvement of the overall elastic performance of the shoe sole.

[0042] From the perspective of mechanics, when the sole is subjected to external force, whether it is the vertical body weight pressure or the lateral friction force and torsional force generated by the change of foot action in the process of walking and movement, the hinged second support column 6 can respond flexibly. Unlike rigid fixed connection, the hinge makes the second support column 6 no longer limited to a single fixed posture, and it can swing around the hinge point within a certain amplitude. For example, when the wearer is walking, the rear side of the sole is subjected to a backward impact force at the moment of foot landing. At this time, the upper end of the second support column 6 has a tendency to move backward with the lower sole 22, and the hinge structure of the lower end allows the lower end to swing relative to the bottom support 3. This swinging process can effectively buffer the instantaneous impact force and prevent the impact force from being directly and rigidly transmitted to other parts of the sole, preventing local stress concentration from causing sole damage or discomfort.

[0043] Moreover, during the continuous deformation process of the sole under stress, the swing of the second support column 6 can dynamically adjust the relative position relationship between the various components of the sole, further optimizing the distribution of force in the sole structure. For example, when the wearer performs a turning action, the stress on one side of the sole increases, and the second support column 6 adjusts the stress distribution between the bottom support 3 and the lower sole 22 through swinging, allowing the overall deformation of the sole to be more uniform and natural, thereby enhancing the sole's ability to cope with complex external force environments in all directions.

[0044] Furthermore, the second support column 6 is made of metal material, which is also a well-considered choice. Metal materials have high strength and rigidity, and can ensure the stability of their own structure when subjected to large external forces, preventing easy bending deformation or breaking, and providing reliable support for the sole. At the same time, although metal is relatively rigid compared to other materials, in combination with its hinge design with the lower sole 22 and the bottom support 3, it can also play a role similar to an "elastic skeleton" during the elastic deformation of the sole, assisting and guiding the deformation of the various components of the sole according to the reasonable mechanical law, and further expanding the elastic deformation space of the sole in cooperation with other elastic components such as the slot 1, the first deformation cavity 7 and the second deformation cavity 8, etc., to improve the cushioning and rebound performance of the sole in various movement scenarios and daily walking conditions, and to provide the wearer with a more outstanding foot support and comfortable experience.

[0045] Another implementation structure, when the second support column 6 is integrally provided with the lower sole 22 and the bottom support 3, the elastic sole involved in the present patent still exhibits many outstanding advantages.

[0046] In terms of elastic performance, the slot 1 on the bottom surface of the heel of the sole body 2 penetrates multiple sides. This unique design enables the sole to deform in multiple dimensions when subjected to force, effectively breaking through the rigid constraints of traditional soles and opening up a new elastic mode. The bottom support 3 is connected to the sole body 2 in combination with the connecting strip 4 and the integrated support structure, creating the first deformation cavity 7 and the second deformation cavity 8. The air in the cavities is compressed and released along with the sole, perfectly matching the overall deformation of the sole, efficiently absorbing and dispersing the impact force from the ground, and significantly improving the sole's rebound performance. Although the second support column 6 is integrally provided, as a key support part of the sole structure, it plays a stable guiding role in the deformation process of the sole by virtue of its reasonable mechanical layout. For example, when the wearer is walking, the rear side of the sole is subjected to pressure, and the entire sole structure relies on the integrated support system to adjust the deformation of each part in an orderly manner, ensuring that the elastic response is timely and accurate, effectively buffering the impact force in the moment of landing. In the turning action, the integrated second support column 6 cooperates with other components to evenly distribute the force on the sole, allowing the sole to deform smoothly and naturally, and confidently responding to complex external force changes, providing comprehensive protection for the elasticity of the sole.

[0047] From the perspective of structural stability, the lower sole 22 is harder than the upper sole 21, and the lower sole 22 takes on the key role of main support, even if it encounters strong impact from intense exercise, it can still maintain the stability of the sole structure and firmly prevent the risk of collapse, providing a solid and reliable framework foundation for the free deformation of the slot 1. Moreover, the integrated setting of the lower sole 22, the connecting strip 4, the first support column 5, the second support column 6, and the bottom support 3 completely eliminates the connection gaps and potential weak links between components, enabling the force to be transmitted within the sole like a high-speed train running smoothly and unobstructed, effectively ensuring the stable and efficient operation of the elastic mechanism, and providing protection for the durability of the sole.

[0048] The first support column 5 and the second support column 6 are arranged in a spreader shape. From the perspective of force distribution, when the sole bears the weight of the human body and external forces during walking and exercise, the spreader-shaped arrangement can make the support force more evenly distributed to the heel area of the sole. Compared to parallel arrangement, the spreader-shaped structure makes the support point of the support column form a certain angle with the sole body 2 in the vertical direction, and performs outstandingly in dealing with lateral forces. For example, in the movement scenario of rapid turning and side movement, the spreader-shaped support column can guide the sole to produce adaptive deformation according to the direction of external force, effectively preventing the sole from turning over and enhancing the stability of wearing. At the same time, this layout cooperates with the slot 1 on the heel of the sole body 2 to provide differential support intensity on both sides of the slot 1 during the deformation of the sole, prompting the slot 1 to stretch and compress more reasonably, and further optimizing the elastic performance of the sole.

[0049] The connecting strip 4 is arranged with a middle high and two ends low, and is arranged in an upward arch shape. The upward arch shape makes the connecting strip 4 have a certain elastic reserve capacity. When the shoe sole is subjected to force, the connecting strip 4 can deform like a spring before other parts of the shoe sole, buffer part of the impact force, and uniformly transmit the force to the shoe sole. Especially when the shoe sole is subjected to vertical pressure, the arch part is pressed to sink, through the elastic deformation process of itself, absorbs energy, reduces the influence of instantaneous impact force on the overall structure of the shoe sole. In addition, the shape design of the connecting strip 4 cooperates with the first support column 5, the second support column 6 and the bottom support 3 to jointly build a more three-dimensional and flexible mechanical support network, optimize the elastic response mechanism of the shoe sole under different stress states, and improve the durability and comfort of the shoe sole.

[0050] An elastic shoe comprises the elastic shoe sole, and the upper side of the shoe sole body 2 is provided with a vamp 23.

[0051] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
