Description

Technical Field

[0001] This invention relates to the field of footwear technology, specifically to a double-heeled high heel shoe. Background Technology

[0002] High heels, as a common footwear product, are widely used in daily wear and formal occasions. They improve the posture and appearance of the human body by raising the position of the heel. However, existing high heels usually adopt a single heel support structure in their structural design, and the sole is generally rigid, which leads to obvious problems of unreasonable stress during wear. Specifically, due to the high heel height, the body's center of gravity shifts significantly forward when wearing high heels, causing the forefoot area to bear a large amount of concentrated pressure for a long time. At the same time, the heel, as the main support point, also continuously bears the pressure from the body weight. During walking or standing for a long time, the forefoot and heel areas are repeatedly pressured, which can easily cause local fatigue, pain or even injury, seriously affecting the comfort of wearing them. The existing high heels with publication number CN103547179A improve the contact between the arch and the sole by setting a fixed support structure at the arch, thereby reducing the pressure on the ball of the foot and heel. However, in application, the contact pressure between the fixed support structure and the arch is fixed, which not only increases the feeling of foreign objects under the foot, but also increases the pressure on the heel after wearing for a long time or the pressure on the forefoot during walking. Furthermore, it lacks effective cushioning and is difficult to adapt to changes in force, resulting in the arch being unsupported or insufficiently supported, further aggravating the problem of concentrated force on the forefoot. The impact force is difficult to disperse and transmit, which easily causes discomfort in the heel area.

[0003] Similar to the above solutions, existing technologies include methods to improve comfort by adding insoles, using soft materials, or setting up air cushion structures. However, these methods are mostly focused on local cushioning and fail to optimize from the perspective of the overall force path. They are still difficult to effectively solve the problem of simultaneous pressure on the forefoot and heel, and they also have certain deficiencies in terms of stability and support. Therefore, how to distribute and buffer the force through reasonable structural design while ensuring the structural stability of high heels, reduce the pressure on the forefoot and heel areas, and improve the arch support effect to enhance overall wearing comfort has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a double-heeled high heel shoe to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a double-heeled high heel, including a sole, a first heel, and a double-heel mechanism disposed on the right side of the sole. The first heel is the main load-bearing structure, used to bear the main weight of the human body and ensure the overall structural stability. The double-heel mechanism is disposed on one side of the first heel, and the force distribution mode of the traditional single heel is changed by introducing a secondary support structure.

[0006] The double-heel mechanism includes a second heel and an elastic component disposed between the second heel and the first heel, enabling the second heel to undergo vertical elastic displacement relative to the first heel. Thus, when the wearer is walking or standing, and the force on the heel area increases, the second heel can move downward in a controlled manner. The impact force is absorbed and released through the compression and rebound of the elastic component, reducing the instantaneous peak force on the heel and alleviating the discomfort caused by continuous pressure.

[0007] The shoe sole is equipped with an arch support mechanism in the middle, which includes an elastic steel plate arranged along the front-to-back direction of the sole. The two ends of the elastic steel plate are connected to the first heel, thus forming an elastic force-bearing component that spans the arch area. An arch support plate is provided above the elastic steel plate, and a bottom fixing plate is provided below it. The three form a clamping structure. When the sole is pressed down, the elastic steel plate bends and deforms, and supports the arch support plate upward through its rebound characteristics, so that the arch area receives dynamic support, effectively making up for the problem of insufficient arch support in traditional high heels.

[0008] The elastic displacement of the second heel works in conjunction with the deformation of the arch support mechanism, allowing the cushioning deformation of the heel area to be transmitted to the middle of the sole and triggering a response from the arch support structure. This creates a continuous force distribution path from the heel to the arch and then to the forefoot, thus distributing the force to the forefoot, reducing the pressure concentration in the forefoot area, and improving overall walking stability and comfort.

[0009] Furthermore, the upper left and right sides of the first heel have two parallel support frame structures with a space between them. This structure not only helps to reduce the overall weight, but also provides installation space for elastic components and related connecting structures, while improving the structure's resistance to lateral deformation.

[0010] Furthermore, the sole has two limiting openings extending in the left and right directions. The left end of the first heel is inserted into the limiting opening, and the front and rear sidewalls of the limiting opening are used to limit the first heel. This limiting structure can effectively suppress the back-and-forth movement of the first heel relative to the sole, enhance the connection reliability, and prevent loosening or displacement during repeated stress.

[0011] Furthermore, an installation port is provided in the middle of the sole between the two limiting ports. The installation port is arranged through the sole thickness direction to accommodate the arch support mechanism and provide sufficient deformation space for the elastic steel plate, so that it can fully exert its elastic deformation capacity during the stress process and avoid structural interference affecting the support effect.

[0012] Furthermore, the first heel has mounting grooves on the front and rear sides of the mounting opening, and the two ends of the elastic steel plate are respectively embedded and fixed in the mounting grooves, thereby achieving a stable and reliable connection method, preventing the elastic steel plate from shifting or falling off during long-term repeated deformation, while ensuring the effective transmission of force.

[0013] Furthermore, the arch support plate has an arc-shaped structure, with its left and right ends fixedly connected to the inner wall of the mounting opening, and its middle part raised towards the upper surface of the sole. This structure can better conform to the curve of the human foot arch, providing support while avoiding local pressure and improving wearing comfort.

[0014] Furthermore, the bottom fixing plate is a flat plate structure, with its left and right sides fixedly connected to the lower surface of the shoe sole, and forming a gap space between it and the arch support plate. This gap is used to accommodate the deformation of the elastic steel plate, so that it has sufficient room to move during the stress process, thereby ensuring the sensitivity and stability of the elastic response.

[0015] Furthermore, the elastic component is a compression spring, which is arranged vertically. Its upper end is fixedly connected to the second heel, and its lower end is fixedly connected to the first heel. This structure is simple and reliable, and can generate a stable rebound force when compressed, thus achieving a continuous cushioning effect.

[0016] Furthermore, the double-heel mechanism also includes a limiting hinge block and a hinge post. The upper end of the limiting hinge block is hinged to the second heel, and the middle part is hinged to the hinge post, thereby forming a multi-point hinged guide limiting structure, which enables the second heel to guide during vertical movement, avoid deviation or tilting, and improve movement stability.

[0017] Furthermore, the lower side of the limiting hinge block is an arc-shaped structure that bends to the right. When the second heel moves down to the preset stroke, the arc-shaped structure abuts against the outer wall of the first heel, thereby forming a rigid limit, restricting the maximum displacement of the second heel, preventing excessive compression of the elastic component, and improving the safety and durability of the overall structure.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are: By incorporating a double-heel mechanism and elastic components, the second heel can undergo vertical elastic displacement during walking or standing, buffering and absorbing the force on the heel. This transforms the concentrated impact force on the heel into elastic deformation energy, effectively reducing the continuous pressure on the heel area and alleviating fatigue and pain caused by prolonged stress.

[0019] By incorporating an elastic steel plate and an arch support plate, the shoe can undergo adaptive elastic deformation during the compression of the sole, and lift the arch area upwards, providing dynamic support to the arch. This distributes the pressure on the forefoot, reduces stress concentration in the forefoot area, and significantly alleviates discomfort and pain caused by prolonged pressure on the forefoot.

[0020] By incorporating a linked structure with a double heel mechanism and an arch support mechanism, the sole of the shoe can undergo coordinated deformation while the heel undergoes elastic displacement. This redistributes the force among the heel, arch, and forefoot, creating a continuous and cushioned force transmission path. Overall, this reduces the pressure intensity in the front and rear areas, improving stability and comfort during walking. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0023] Example 1: Please refer to Figure 1-13 The present invention provides a technical solution: a double-heeled high heel, including a sole 2, a first heel 1 and a double heel mechanism 5 disposed at the heel of the sole 2, wherein the first heel 1 is the main load-bearing structure, and its whole is in the form of a split double support structure. The two support frames are spaced apart in the front-back direction and are interlocked with each other on the upper side and the lower side of the sole 2, thereby forming a stable force-bearing foundation. A double heel mechanism 5 is provided on the right side of the first heel 1. The double heel mechanism 5 includes a second heel 501 and two compression springs 502 disposed between the second heel 501 and the first heel 1. The compression springs 502 are arranged vertically, with their upper ends fixedly connected to the lower structure of the second heel 501 and their lower ends fixedly connected to the upper surface of the right end of the first heel 1, so that the second heel 501 can generate a vertical elastic displacement relative to the first heel 1 when subjected to force, thereby buffering the impact force when the wearer walks or stands. An arch support mechanism 6 is provided in the middle of the sole 2. The arch support mechanism 6 includes an elastic steel plate 602 arranged along the front and rear direction of the sole 2. The front and rear ends of the elastic steel plate 602 are respectively embedded and fixed in the mounting groove 601 on the first heel 1. An arch support plate 604 is provided above the elastic steel plate 602 and a bottom fixing plate 603 is provided below it. The three form a clamping structure. During use, when the wearer walks or the right end of the sole 2 is compressed, the second heel 501 is compressed and displaced under the action of the compression spring 502. At the same time, the sole 2 deforms downward, which in turn causes the elastic steel plate 602 to support the arch support plate 604. The arch support plate 604 is pushed upward relative to the sole 2, providing support for the arch area, thereby reducing pressure on the forefoot area and improving wearing comfort and stability.

[0024] Example 2: Please refer to Figure 1-13Based on Embodiment 1, the present invention provides a technical solution: two limiting openings 3 extending in the left and right directions are provided on the sole 2, the left end of the first heel 1 is inserted into the limiting opening 3, and the front and rear side walls of the limiting opening 3 and the outer wall of the first heel 1 form a fitting structure. With the above settings, the first heel 1 is not only fixedly installed when connected to the sole 2, but also effectively constrained in the front and back directions, thereby preventing loosening or displacement during long-term stress or dynamic walking, and improving the overall structural stability. Meanwhile, an installation opening 4 is provided in the middle of the sole 2 between the two limiting openings 3. The installation opening 4 is provided through the sole thickness direction to accommodate the arch support mechanism 6. The arch support plate 604 adopts an arc structure design. Its left and right ends are fixedly connected to the inner wall of the installation opening 4, and the middle part is raised upward to make its shape more in line with the curve of the human arch. The bottom fixing plate 603 is set at the bottom of the mounting port 4. Its left and right sides are fixedly connected to the lower surface of the sole 2 and form a certain gap with the arch support plate 604. This gap is used to provide the elastic steel plate 602 with deformation space when subjected to force. Through this structure, the arch support mechanism 6 has better elastic response capability when subjected to force, avoiding the discomfort caused by rigid pressure.

[0025] Example 3: Please refer to Figure 1-13 Based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: based on the above embodiments, the limiting structure of the double heel mechanism 5 is further improved. The double heel mechanism 5 also includes a limiting hinge block 503 and a hinge post 504. The hinge post 504 is fixedly disposed on the upper surface of the right end of the first heel 1. The upper end of the limiting hinge block 503 is hinged to the second heel 501, and the middle part is hinged to the hinge post 504, thus forming a multi-point hinge structure, which enables the second heel 501 to have a guiding effect during vertical movement and avoids tilting or swaying. Furthermore, the lower side of the limiting hinge block 503 is configured as an arc-shaped structure that bends to the right. When the second heel 501 is compressed downward to the preset stroke, the lower end of the arc-shaped structure will contact the outer wall of the first heel 1, thereby forming a rigid limit and restricting the maximum downward stroke of the second heel 501. By setting the above-mentioned limiting structure, on the one hand, it can prevent the compression spring 502 from being over-compressed and causing structural failure, and on the other hand, it can avoid instability caused by excessive heel sinking, thereby improving the overall structural safety and durability while ensuring the cushioning effect.
