Description

Technical Field

[0001] The utility model relates to the technical field of shoes, in particular to a pair of shoes with convenient insoles to be taken out. Background Art

[0002] In today's footwear market, shoes, as an essential daily wear item, have always garnered significant attention for their internal structural design. To enhance comfort, warmth, and moisture-wicking properties, most shoe styles incorporate insoles. As the part that directly contacts the foot, insoles effectively cushion the impact of walking, protect foot joints, and absorb perspiration, keeping the shoe dry.

[0003] However, for a long time, traditional footwear designs have had significant deficiencies in the ease of access to insoles. On the one hand, insoles are usually customized according to the shape of the shoe's inner cavity and fit tightly to the bottom of the shoe to ensure that they do not shift or wrinkle during walking, thereby affecting the wearing experience. This tight fit makes it difficult for users to remove the insoles. For example, it is difficult to insert fingers smoothly into the narrow gap between the insole and the wall of the shoe's inner cavity. Forcible pulling can easily cause the insole to deform or even damage the insole or the shoe itself. Especially for some shoes with a deeper shoe cavity and a high-top design, the limited space for hand operation greatly increases the difficulty of removing the insole.

[0004] On the other hand, some insoles utilize special rubber materials or textured designs on the bottom to enhance their anti-slip properties. While this effectively prevents the insoles from sliding during everyday wear, it further increases the friction between the insoles and the shoe's inner sole, making their removal a laborious and time-consuming task. In situations such as cleaning the insoles or replacing insoles with different functions (e.g., professional shock-absorbing insoles for exercise, soft and comfortable insoles for daily leisure), the inconvenience of operation causes great distress to users and seriously affects the overall practicality of the footwear product. Therefore, solving the problem of insole removal has become a key technical difficulty that needs to be overcome in the field of footwear design. Utility Model Content

[0005] In view of the problems pointed out in the background technology, the present invention proposes a shoe with convenient insole removal to solve the above technical problems.

[0006] The technical solution of the present utility model is achieved as follows:

[0007] A shoe with convenient insole removal comprises a sole, an upper portion of the sole being provided with a shoe upper, an insole being provided inside the shoe, a handle being provided at the rear end of the shoe upper, one end of the handle being fixedly connected to the shoe upper, and the other end of the handle being a free end; and a connecting strip being further provided, one end of the connecting strip being fixedly connected to the other end of the handle, and the other end of the connecting strip being connected to the rear end of the insole.

[0008] The utility model is further configured such that the other end of the connecting strip is fixedly connected to the rear end of the insole.

[0009] The present invention is further configured such that the other end of the connecting strip is detachably connected to the rear end of the insole.

[0010] The present invention is further configured such that the width of the handle is greater than the width of the connecting strip.

[0011] The utility model is further configured such that the other end of the handle is provided with a bristle surface of Velcro, and the inner side surface of the rear end of the shoe upper is provided with a corresponding round bristle surface of Velcro.

[0012] The present invention is further configured such that the other end of the connecting strip is fixedly connected to the rear end of the insole via stitching.

[0013] The present invention is further configured such that the other end of the connecting strip is detachably connected to the rear end of the insole via a Velcro or a snap fastener.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] In terms of ease of use, the insole removal is greatly enhanced by providing a handle at the rear end of the upper, which is wider than the connecting strip. No longer needing to laboriously dig at the edge of the insole, the user simply grasps the wide handle, providing ample grip space, applies even force, and smoothly pulls the insole out. This is particularly user-friendly for those with limited hand strength or dexterity, such as the elderly and children, achieving truly barrier-free operation and significantly saving time and effort when removing and placing the insole.

[0016] The handle's secure connection to the rear end of the upper, along with the optimally designed width of the connecting strip, contribute significantly to its structural stability. The wider handle provides a larger contact area with the upper, ensuring it stays in place during everyday wear, regardless of whether it uses Velcro or other fastening methods. The narrow connecting strip, however, flexibly adapts to the dynamic deformation of the insole. These two elements work together to ensure smooth transmission of tension during insole removal, effectively preventing component breakage and deformation and ensuring the long-term reliable operation of the entire insole removal mechanism.

[0017] Furthermore, the diverse connection methods, such as stitching the connecting strip to the rear end of the insole or detachable connections using Velcro or snap-on buckles, make the shoes highly practical. On the one hand, the stitching is durable and can withstand the various external forces of daily wear; on the other hand, the detachable connection facilitates cleaning and replacement of the insole, meeting the user's diverse needs for insole functionality in different scenarios, such as quickly switching between professional shock-absorbing and breathable insoles for exercise and leisure.

[0018] Overall, the patented design of this shoe comprehensively optimizes the insole retrieval experience, taking into account both structural stability and diverse functions, bringing consumers unprecedented comfort and convenience, and has great market value. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] 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.

[0025] Reference as follows Figure 1-3 The utility model is described as follows:

[0026] Example: A shoe with easily removable insoles includes a sole 1, which serves as the foundational support for the entire shoe, bearing the weight of the human body and providing a stable foothold for activities such as walking and exercise. The sole 1 is typically made of materials such as rubber and polyurethane that exhibit excellent wear resistance, flexibility, and anti-slip properties. The thickness and pattern of the sole 1 vary depending on the intended use of the shoe, adapting to various surface conditions and ensuring safe and comfortable walking for the wearer.

[0027] Upper 2 sits on the upper side of sole 1. This upper not only protects the foot from external impact and friction but also significantly influences the shoe's appearance. Upper 2 can be made of a variety of materials, including leather, fabric, and synthetics. Each material offers varying textures, breathability, and durability. For example, leather uppers offer a premium feel and excellent water resistance, making them popular for business and formal wear. Fabric uppers, on the other hand, offer superior breathability and are a popular choice for athletic and casual shoes.

[0028] The shoe is fitted with an insole 3, which sits snugly above the sole 1 and directly contacts the foot. It offers a variety of functions. Firstly, it cushions the impact of the ground during walking and running, reducing pressure on foot joints and preventing sports injuries. Secondly, it absorbs foot sweat, keeping the shoe dry, reducing odor, and enhancing wearing comfort. Common materials for the insole 3 include sponge, EVA foam, and silicone. A combination of materials is used depending on the functional requirements to achieve optimal cushioning and sweat absorption.

[0029] A special feature of the shoe is the meticulously designed handle 4 at the rear end of the upper 2. One end of the handle 4 is securely attached to the upper 2, ensuring it won't fall off easily when stressed, maintaining structural stability. The other end is free, allowing the user to easily grasp and apply force. The shape and size of the handle 4 are designed with ergonomic considerations in mind, ensuring it's easy to grip while avoiding scratches or discomfort during wear. Typically, the handle features rounded edges and is made of a material that balances softness and toughness, such as a soft plastic or rubber-wrapped metal strip.

[0030] Even more crucial is the connecting strip 5, which bridges the gap between the handle 4 and the insole 3. One end of the connecting strip 5 is securely attached to the free end of the handle 4, while the other end precisely connects to the rear end of the insole 3. The material selection for the connecting strip 5 is crucial: it needs to possess a certain strength to withstand the tensile forces of the insole 3 and prevent breakage; yet possess appropriate flexibility to allow the insole 3 to naturally flex and move with the foot during daily wear. A strip-like connecting strip made of materials like nylon provides both the required strength and the flexibility to adapt to various deformation requirements.

[0031] With this overall structural design, when the user needs to remove the insole 3, they no longer need to laboriously dig at the edge of the insole with their fingers. Instead, they simply gently grasp the free end of the handle 4 and apply a suitable pulling force outward. Through the conduction of the connecting strip 5, the insole 3 can be smoothly and completely pulled out of the shoe. The entire operation process eliminates the tedious and inconvenient traditional insole removal method, greatly improving the convenience of removing and placing the insole. Whether it is daily insole cleaning and replacement or insole replacement for different scenarios, it can be completed easily and efficiently, effectively optimizing the user experience of the shoes.

[0032] In the design of this innovative shoe that allows for easy removal of the insole, the connection method between the connecting strip 5 and the rear end of the insole 3 is a key detail. Different connection implementation structures have their own advantages and disadvantages, bringing diverse changes to the overall performance of the shoe.

[0033] Implementation structure 1: Suture fixed connection:

[0034] When the other end of the connecting strip 5 is fixedly connected to the rear end of the insole 3 with stitches, this method establishes a stable and lasting connection. From a process point of view, high-strength sewing thread, such as polyester fiber thread, is usually used for sewing operations. It has good wear resistance and tensile strength, and can maintain the integrity of the connection under repeated pulling. In the production process, professional shoemakers will accurately adjust the density of the stitches and the direction of the stitches according to the material properties of the insole 3 and the connecting strip 5. For thicker insole materials, such as multi-layer composite EVA foam insoles, double-line cross-stitching may be used to ensure that the stitches can penetrate each layer of material to make the connection more secure; for relatively thin insoles, such as sponge insoles, fine and uniform stitches can ensure the strength of the connection without excessively damaging the insole material.

[0035] In terms of long-term use effects, this type of suture fixed connection can effectively resist various pulling forces during daily walking and exercise. Whether it is the forward and backward displacement force exerted on the insole 3 when the wearer runs fast, or the external force generated by improper operation when frequently taking off or putting on shoes, the suture can tightly hold the connecting strip 5 and the insole 3 together to prevent the two from separating, thereby ensuring the reliability of the insole removal and placement mechanism. In addition, since the suture fits tightly to the insole and the connecting strip, there are no additional loose parts, and no abnormal noise or foreign body sensation will be generated in the shoe, making the wearing experience more comfortable and natural. However, the suture fixed connection method is relatively fixed. Once the insole 3 is severely worn and needs to be replaced, the process of removing the suture is relatively cumbersome and requires the use of professional tools. It is also easy to cause certain damage to the insole 3 or the connecting strip 5, which is not conducive to convenient replacement of the insole.

[0036] Implementation structure 2: Velcro or snap fastener detachable connection:

[0037] If the other end of the connecting strip 5 is detachably connected to the rear end of the insole 3 via Velcro or snap fasteners, this provides the shoe with exceptional flexibility. Velcro consists of a hook and loop surface, while snap fasteners consist of two matching male and female components. Their common feature is that they allow for quick and convenient connection and easy detachment.

[0038] In actual use, when the user needs to clean the insole 3, they simply tear the Velcro or undo the snap fastener to quickly separate the insole 3 from the connecting strip 5. This entire process can be completed by hand without the need for additional tools, significantly saving time and effort. Furthermore, this detachable connection allows the user to easily replace the insole 3 with a different function based on their needs. For example, when engaging in outdoor sports, a thick insole with professional shock absorption and support can be used; when commuting, a thin, soft, and breathable insole can be used to meet diverse comfort needs.

[0039] From a manufacturing perspective, Velcro or snap fasteners are relatively simple to install and can be attached or fastened after the insole 3 and connecting strip 5 are formed. This process does not require complex sewing processes, reducing production difficulty and costs. However, this connection method also has certain limitations. The hook and loop surfaces of Velcro are prone to absorbing dust, hair, and other debris during repeated pasting and tearing, affecting the pasting effect and causing the connection to become loose. Snap fasteners may become loose due to frequent opening and closing, especially in high-intensity sports scenarios. The insole 3 is at risk of detaching from the connecting strip 5, thus affecting the overall functionality of the shoe.

[0040] In summary, the two implementation structures have their own advantages and disadvantages. Under different usage scenarios and needs, they provide a variety of technical options for this shoe that is easy to remove the insole, so as to meet consumers' requirements for convenience, durability and other aspects.

[0041] The width of the handle 4 is greater than the width of the connecting strip 5. This design detail is of key significance first from the perspective of force. When the user needs to pull the insole 3 out of the shoe through the handle 4, the larger width of the handle 4 can effectively disperse the pulling force applied by the hand. Compared with the narrower connecting strip 5, the handle 4 provides more ample gripping space for the fingers, so that the force can be evenly distributed over a larger area. In this way, during the pulling process, whether it is instantaneous explosive force or continuous and stable pulling force, the handle 4 or the connecting strip 5 will not break or deform due to excessive local force, thereby ensuring the reliability and durability of the entire insole removal mechanism.

[0042] The relatively narrow width of the connecting strip 5, on the other hand, is a result of a comprehensive consideration of the shoe's interior space layout and its own functional characteristics. Connecting strip 5 primarily provides a flexible connection between the insole 3 and the handle 4, transmitting tension. Unlike the handle 4, it does not require direct gripping. Its narrow width reduces its footprint within the shoe, minimizing any impact on foot comfort. It also reduces material costs and manufacturing complexity.

[0043] The other end of the handle 4 is provided with a bristle surface 61 of a Velcro, and the inner side surface of the rear end of the upper 2 is provided with a corresponding round bristle surface 62 of the Velcro.

[0044] The handle 4, a key component for removing the insole 3, is ingeniously designed not only in its synergistic effect with the connecting strip 5 but also in its flexible connection to the upper 2. The other end of the handle 4 features a Velcro-like bristle surface 61, while the inner rear surface of the upper 2 is meticulously fitted with a Velcro-like bristle surface 62.

[0045] From the perspective of normal daily use, the insole 3 is safely located inside the shoe most of the time, performing basic functions such as cushioning and sweat absorption, and does not need to be removed frequently. At this time, the presence of the handle 4 does not cause any interference with daily wear. Thanks to the Velcro structure, the other end of the handle 4 fits tightly on the inner side of the rear end of the upper 2, and the burr surface 61 and the rounded burr surface 62 are firmly bonded, and the two together form a ring. This ring structure cleverly maintains the original position of the handle 4, preventing the handle 4 from shaking freely in the shoe, and preventing it from hanging abruptly outside, preventing the handle 4 from getting caught on other objects during walking or exercise, posing a potential safety hazard to the user.

[0046] Furthermore, in this annular state, the handle 4 retains its intended function. If the user needs to clean the insole 3 or replace it with a different one, they can simply apply a little force to overcome the adhesive force between the Velcro strips and separate the bristled surface 61 of the handle 4 from the rounded surface 62 of the upper 2, restoring the handle to a freely operable state. The user then applies outward force through the handle 4, which, thanks to the conduction of the connecting strip 5, smoothly pulls the insole 3 out of the shoe.

[0047] From the perspective of material selection and process implementation, the selection of Velcro is not random. The material of the round hair surface 62 used for the upper 2 must ensure sufficient viscosity to firmly fix the handle 4 during daily wear, and must also be soft so as not to have a negative impact on the texture and comfort of the upper 2. Usually, a round hair surface made of nylon with a fine texture and soft velvet is selected. The bristle surface 61 on the handle 4 has a certain wear resistance while ensuring good adhesion performance, preventing damage to the bristles caused by frequent opening and closing, which affects the service life of the Velcro. A bristle structure made of high-strength polyester fiber is often used. In terms of manufacturing technology, the installation of Velcro requires precise positioning. Whether it is sewing the round hair surface 62 on the upper 2 or integrating the bristle surface 61 when the handle 4 is formed, strict tolerance control is required to ensure that the two can perfectly match and fit together to achieve a stable and reliable connection effect.

[0048] In general, the dynamic connection design between the handle 4 and the rear end of the upper 2 formed by Velcro fully takes into account the needs of the shoes in different stages of use. While ensuring the convenience of daily wear, it also ensures the convenience of operation when removing the insole, providing users with a more intimate and efficient wearing experience.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
