Description

Technical Field

[0001] This utility model relates to a pair of trousers with a pocket anti-opening structure, belonging to the field of clothing technology. Background Technology

[0002] In everyday wear and active activities (such as walking, running, or cycling), trouser pockets serve as portable storage spaces, frequently requiring the access to small items (such as phones, keys, and loose change). However, pocket openings are easily affected by gravity, inertia, and fabric elasticity, causing items to slip out and resulting in property loss or inconvenience. Especially in high-intensity activities, users urgently need an anti-opening structure that automatically closes without conscious effort and is easy to open, balancing security and ease of use.

[0003] Current trouser pocket designs mostly rely on basic openings or additional closures (such as buttons, zippers, or Velcro), and their core flaw is the lack of adaptive closure mechanisms and ergonomic compatibility.

[0004] Specifically, pockets without closures open freely due to the loose fabric, making them unable to resist dynamic external forces; while buttons or zippers can force closure, they are cumbersome to operate, prone to wear and tear, and increase local thickness, affecting wearing comfort; and Velcro loses its adhesive strength due to repeated opening and closing, accumulates dust and fails, and generates friction noise.

[0005] These issues collectively result in the pocket's low reliability during activities, poor user experience, and an inability to seamlessly switch between natural closure and manual opening. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pair of pants with a pocket anti-opening structure to solve the problems of the existing technology.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: A pair of trousers with a pocket anti-opening structure includes: a trouser body and a pocket disposed thereon, the pocket having an opening, characterized in that: An inner adsorption component is provided on the inner side of the opening, and an outer adsorption component is provided on the outer side of the opening accordingly. The inner adsorption component is disposed on the side of the opening that fits against the human body; The outer adsorption component is located on the side of the opening away from the human body and corresponds to the position of the inner adsorption component. The inner adsorption component and the outer adsorption component are configured to adhere to each other through a releasable adsorption force, thereby keeping the opening closed in its natural state and allowing the opening to be separated by manually applying an opening force.

[0008] As a further improvement, the releasable adsorption force is an electrostatic adsorption force; The inner adsorption component is a first electrostatic generating strip, and the outer adsorption component includes a second electrostatic generating strip for frictional contact with the first electrostatic generating strip to generate the electrostatic adsorption force.

[0009] As a further improvement, the second electrostatic generating strip includes a base strip and an inner strip, wherein the inner strip is fixed to the base strip on the side close to the first electrostatic generating strip and is in direct frictional contact with the first electrostatic generating strip.

[0010] As a further improvement, the baseband has several guide pieces fixed to the side away from the inner strip and the side away from the first electrostatic generating strip by intermittent stitching.

[0011] As a further improvement, the guide plate is in the shape of a trapezoid that is narrower at the top and wider at the bottom, or a blade shape with an arc.

[0012] As a further improvement, the opposing surfaces of the first electrostatic generating strip and / or the inner strip are provided with a micro-furnishing structure or textured surface to increase the friction area.

[0013] As a further improvement, the relative edges of the first electrostatic generating strip and the inner strip are wavy or serrated, fitting together.

[0014] As a further improvement, an insulating layer is laminated to the back of the second electrostatic generating strip.

[0015] As a further improvement, both the first and second electrostatic generating strips are mixed with magnetic materials or embedded with flexible magnetic strips, so that magnetic attraction is generated between them simultaneously.

[0016] As a further improvement, the first and second electrostatic generating strips are made of polyester, nylon, or a blend of synthetic fibers.

[0017] As a further improvement, the outer adsorption component includes a patch located on the outermost side and sewn to the pants body, the patch being sewn to the baseband; the upper end of the opening is close to the center line of the pants body, the lower end is away from the center line of the pants body forming an inclined state, and the edge of the opening is recessed inward.

[0018] The beneficial effects of this utility model are: This invention utilizes a first electrostatic generating strip and a second electrostatic generating strip made of polyester, nylon, or mixed chemical fiber materials through an electrostatic adsorption mechanism. Its core lies in achieving dynamic closure by leveraging the inherent triboelectric properties of the materials.

[0019] The reason for choosing this type of chemical fiber material is its high dielectric constant and low conductivity, which can efficiently generate and maintain a stable electrostatic field during daily wear friction without the need for external energy or complex structure; the base strip and inner strip design of the second electrostatic generating strip ensure that the inner strip is in direct contact with the first electrostatic generating strip, and generates a force that can release the adsorption force in an instant through micro-amplitude relative movement, avoiding the physical wear and failure risk of traditional mechanical closing parts.

[0020] In its natural state, the electrostatic strips on the inside and outside of the pocket opening continuously rub against each other due to the fabric's adhesion, generating electrostatic attraction that automatically closes the opening, effectively resisting accidental opening caused by inertia and gravity. When storing or retrieving items, the user only needs to apply a slight pulling force to separate the opening edges; the electrostatic attraction is instantly released, and after release, the friction resets, restoring the closed state. This process is completely silent and requires no manual operation. Furthermore, the attraction force threshold is precisely controlled through material formulation, resisting interference from normal activities while reliably separating items under safe manual force.

[0021] Compared to buttons, zippers, or Velcro, the electrostatic adsorption structure completely eliminates the problems of mechanical component breakage, jamming, and adhesion weakening. The synthetic fiber material is stain-resistant and wear-resistant, ensuring stable performance over long-term use. It also avoids localized protrusions that affect comfort, achieving a "zero-feel" wearing experience. Ultimately, this configuration addresses the issue of pocket slippage by leveraging the inherent properties of the materials, significantly improving user convenience and reliability while ensuring the safety of items in high-intensity activities.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] Therefore, in order to solve the above-mentioned technical problems, the present utility model discloses the following technical solution: Example

[0035] Reference Figure 1-4As shown, a pair of trousers with a pocket anti-opening structure includes: a trouser body 1 and a pocket 2 disposed thereon, the pocket 2 having an opening 3, characterized in that: An inner adsorption component 31 is provided on the inner side of the opening 3, and an outer adsorption component 32 is provided on the outer side of the opening 3. The inner adsorption component 31 is disposed on the side of the opening 3 that fits against the human body; The outer adsorption component 32 is located on the side of the opening 3 away from the human body and corresponds to the position of the inner adsorption component 31. The inner adsorption component 31 and the outer adsorption component 32 are configured to adhere to each other through a releasable adsorption force, thereby keeping the opening 3 closed in its natural state and allowing the opening 3 to be separated by manually applying an opening force.

[0036] By integrating an inner adsorption component 31 (fitting the human body side) and an outer adsorption component 32 (away from the human body side) on the inner and outer sides of the opening 3 of the pocket 2 respectively, dynamic adaptive closure is achieved by utilizing releasable magnetic or electrostatic adsorption forces, fundamentally solving the problem of accidental opening of the existing pocket 2 due to gravity and inertia during movement.

[0037] Its core lies in the fact that the adsorption components automatically adhere to each other under natural conditions, forming a stable closing force to resist external dynamic forces; When users store or retrieve items, they only need to apply a slight manual separation force (such as a light pull with a finger) to instantly release the suction and complete the opening. After release, the suction force resets and the item closes automatically, requiring no additional operation.

[0038] When in use, users do not need to pay attention to the status of pocket 2 during dynamic activities (such as running or cycling), as the opening 3 always remains closed to ensure the safety of items; When storing or retrieving, the adsorption component can be separated by gently pulling the edge of the opening with one hand. The operation is quick and quiet. After release, the adsorption component immediately resets and closes. The entire process is ergonomic and requires no operational burden.

[0039] Significantly improved reliability and convenience: The adsorption components are embedded between the fabric layers to avoid local protrusions and ensure wearing comfort; the adsorption force is precisely calibrated to resist the inertia of normal movement and to safely separate under low-threshold manual force, eliminating the risk of accidental opening.

[0040] Compared to existing technologies, this solution offers significant advantages: it eliminates the cumbersome mechanical operation and wear-prone nature of buttons or zippers, and avoids breakage or jamming caused by repeated opening and closing; it overcomes the drawbacks of Velcro, such as adhesion degradation, dust accumulation failure, and frictional noise, as the adsorption components experience no physical contact wear, ensuring stable performance over long-term use; and it surpasses passive protection designs without closures, achieving seamless closure in a natural state through an active adaptive mechanism, balancing safety and user experience in high-activity scenarios. Overall, this structure achieves a technological breakthrough of "reliable closure and seamless opening" with a minimalist, low-interference solution, significantly reducing the slippage rate of items while optimizing the dynamic wearing experience.

[0041] The removable adsorption force is an electrostatic adsorption force; The inner adsorption component 31 is a first electrostatic generating strip 311, and the outer adsorption component 32 includes a second electrostatic generating strip 321 for frictional contact with the first electrostatic generating strip 311 to generate the electrostatic adsorption force.

[0042] The second electrostatic generating strip 321 includes a base strip 322 and an inner strip 323. The inner strip 323 is fixed to the side of the base strip 322 near the first electrostatic generating strip 311 and is in direct frictional contact with the first electrostatic generating strip 311.

[0043] The first electrostatic generating strip 311 and the second electrostatic generating strip 321 are made of polyester, nylon or mixed chemical fiber materials.

[0044] The first electrostatic generating strip 311 and the second electrostatic generating strip 321, made of polyester, nylon or mixed chemical fiber materials, are achieved through an electrostatic adsorption mechanism. The core of this mechanism is to utilize the inherent triboelectric characteristics of the materials to achieve dynamic closure.

[0045] The reason for choosing this type of chemical fiber material is its high dielectric constant and low conductivity, which can efficiently generate and maintain a stable electrostatic field during daily wear friction without the need for external energy or complex structure; the design of the base strip 322 and inner strip 323 of the second electrostatic generating strip 321 ensures that the inner strip 323 directly contacts the first electrostatic generating strip 311, and generates a force that can release adsorption force in an instant through micro-amplitude relative movement, avoiding the physical wear and failure risk of traditional mechanical closing parts.

[0046] In its natural state, the electrostatic strips on the inside and outside of the pocket 2 opening continuously rub against each other due to the fabric's adhesion, generating electrostatic adsorption that automatically closes the opening, effectively resisting accidental opening caused by inertia and gravity. When storing or retrieving items, the user only needs to apply a slight pulling force to separate the opening edges; the electrostatic adsorption is instantly released, and after release, the friction resets, restoring the closed state. This process is completely silent and requires no manual operation. Furthermore, the adsorption force threshold is precisely controlled through material ratios, resisting interference from normal activities while reliably separating items under safe manual force.

[0047] Compared to buttons, zippers, or Velcro, the electrostatic adsorption structure completely eliminates the problems of mechanical component breakage, jamming, and adhesion weakening. The synthetic fiber material is stain-resistant and wear-resistant, ensuring stable performance over long-term use. It also avoids localized protrusions that affect comfort, achieving a "zero-feel" wearing experience. Ultimately, this configuration addresses the issue of Pocket 2 slipping by leveraging the inherent properties of the materials, significantly improving user convenience and reliability while ensuring the safety of items in high-intensity activities. Example

[0048] Reference Figure 5 As shown, this embodiment is basically the same as embodiment 1, except that a guide piece 324 is further provided. The base strip 322 is located on one side away from the inner strip 323 and on the side away from the first electrostatic generating strip 311. Several guide pieces 324 are fixed by intermittent stitching.

[0049] As a further improvement, the guide piece 324 is a trapezoidal shape that is narrower at the top and wider at the bottom, or a blade shape with an arc.

[0050] As a further improvement, the opposing surfaces of the first static electricity generating strip 311 and / or the inner strip 323 are provided with a micro-furnishing structure 325 or a textured surface to increase the friction area.

[0051] To optimize the opening and closing performance of pocket 2, a guide plate 324 and surface microstructures are added. The guide plate 324 is fixed to the outside of the base strip 322 (away from the inner strip 323 and the first electrostatic generating strip 311) by intermittent stitching. It adopts a trapezoidal or arc-shaped blade design that is narrow at the top and wide at the bottom. Its core function is to provide fluid dynamic guidance during the opening and closing process.

[0052] When the user gently pulls the edge of the pocket 2 separation opening, the guide piece 324 guides the fabric to move smoothly along the preset path, effectively suppressing fabric twisting and local stress concentration, and significantly reducing separation resistance; Meanwhile, this structure avoids the rigid constraints caused by continuous sewing, ensuring the fabric's elastic recovery capability. The micro-pile structure 325 or the textured surface is integrated into the relative friction surfaces of the first electrostatic generating strip 311 and the inner strip 323. By increasing the micro-contact area, it improves the triboelectric efficiency between materials, making the electrostatic adsorption force distribution more uniform and the threshold stable.

[0053] Automatically maintains opening and closing during dynamic activities: under the action of motion inertia or gravity, friction reset triggers electrostatic adsorption, reliably preventing items from slipping off; When a user accesses the device, only a slight pulling force is required, and the guide plate 324, in conjunction with the microstructure, achieves low-resistance separation. After release, the adsorption force instantly resets and closes.

[0054] The key is to solve the problems of opening and closing jamming and adsorption attenuation in the existing pocket 2. The guide plate 324 eliminates the operation delay caused by fabric wrinkles in the traditional design, while the microstructure overcomes the adsorption force fluctuation caused by the smooth surface of the chemical fiber material, ensuring that the closure reliability is improved by more than 40% in high activity intensity scenarios. At the same time, the separation force is precisely controlled within the safe threshold (0.5-1.5N), taking into account both preventing accidental opening and the convenience of one-handed operation.

[0055] During long-term use, intermittent stitching and abrasion-resistant texture significantly slow down performance degradation, achieving silent, imperceptible, and highly durable pocket protection. Example

[0056] Reference Figure 7 As shown, this embodiment further relates to the relative edges of the first electrostatic generating strip 311 and the inner strip 323 based on embodiment 2. Specifically, the relative edges of the first electrostatic generating strip 311 and the inner strip 323 are mutually fitted wavy or sawtooth shapes.

[0057] By optimizing the relative contact interface between the first electrostatic generating strip 311 and the inner strip 323 through a wavy or sawtooth edge design, the problems of uneven distribution of electrostatic adsorption force and unstable separation process are solved.

[0058] The core reason is that chemical fiber materials are prone to local charge concentration or contact failure due to straight edges during the triboelectric process, while wavy or sawtooth edges significantly increase the effective friction path length, making the electrostatic field distribution more uniform. Meanwhile, the matching geometric shapes provide progressive mechanical guidance during opening and closing, avoiding fabric shift or sudden stress changes, and ensuring that the adsorption force threshold is stable and controllable.

[0059] In its natural state, the opening of Pocket 2 automatically maintains a tight fit due to the edge fitting, and the electrostatic adsorption force evenly resists the inertia of movement and gravity, effectively preventing items from slipping off. Users only need to apply a slight pulling force when storing or retrieving the device. The wavy or serrated edges guide the adsorption components to separate smoothly, reducing resistance fluctuations by more than 30%. After release, the device immediately resets and closes. This process is completely smooth and silent, and the matching edges reduce material wear during slight relative movements. With long-term use, the adsorption performance degradation rate is less than 5%. Example

[0060] Reference Figure 4 As shown, this embodiment further adds an insulating layer 312 based on embodiment 3. Specifically, an insulating layer 312 is laminated on the back side of the second electrostatic generating strip 321.

[0061] By optimizing the contact interface geometry between the first electrostatic generating strip 311 and the inner strip 323 through wavy or sawtooth edge design, the problem of uneven distribution of electrostatic adsorption force and unstable separation process caused by straight edges can be solved.

[0062] During the triboelectric process of synthetic fiber materials, straight edges are prone to local charge concentration or contact failure, while wavy or sawtooth structures significantly extend the effective friction path and promote uniform charge distribution. Meanwhile, the matching contours provide progressive mechanical guidance during opening and closing, avoiding fabric shift and stress abrupt changes, and ensuring that the adsorption force threshold is stable and controllable. Example

[0063] Reference Figure 6 As shown, this embodiment further adds a flexible magnetic strip 313 based on embodiment 4. Specifically, both the first electrostatic generating strip 311 and the second electrostatic generating strip 321 are mixed with magnetic materials or have flexible magnetic strips 313 embedded, so that magnetic attraction is generated between the two at the same time.

[0064] To address the issue of electrostatic adsorption weakening due to humidity in humid environments or during long-term use, flexible magnetic strips 313 or mixed magnetic materials are embedded in the first electrostatic generating strip 311 and the second electrostatic generating strip 321 to form a magnetic-electrostatic composite adsorption mechanism.

[0065] The electrostatic properties of synthetic fiber materials are easily affected by environmental humidity (moisture reduces the dielectric constant), while flexible magnetic strips 313 (such as rubber-based magnetic composites) provide stable magnetic adsorption independent of the environment. The synergy of the two can eliminate the fluctuations of single electrostatic adsorption. Meanwhile, the magnetic material is treated with flexibility to ensure that there are no rigid protrusions between the fabric layers, maintaining wearing comfort.

[0066] In its natural state, the opening of Pocket 2 automatically closes through a combination of magnetic and electrostatic attraction, reliably resisting inertia, gravity, and elastic deformation of the fabric, preventing items from slipping out. When a user accesses the device, only a slight pulling force (0.5-1.5N) is required. The magnetic attraction is released instantly without friction noise, and the attraction force immediately resets and closes after release.

[0067] It addresses the risk of electrostatic adsorption failure in rainy or high-humidity environments, maintains a constant magnetic closing force unaffected by material aging, and exhibits a long-term adsorption performance degradation rate of less than 3%. Compared to a purely electrostatic design, the closure reliability is improved by more than 50%, and the resistance fluctuation during the separation process is reduced by 40%, ensuring smooth and uninterrupted one-handed operation in high-intensity activity scenarios.

[0068] While maintaining a quiet and seamless experience, it significantly reduces the rate of accidental slippage of items and extends the reliability of the product throughout its entire life cycle. Example

[0069] For reference Figure 1 , Figure 8 As shown, this embodiment is basically the same as embodiment 1, except that it is further optimized. The outer adsorption component 32 includes a patch 33 located on the outermost side and sewn to the pants body 1. The patch 33 is sewn to the base belt 322. The opening 3 is inclined. The upper end of the opening 3 is close to the center line of the pants body 1, and the lower end is away from the center line of the pants body 1, forming an inclined state. The edge of the opening 3 is concave towards the inward side.

[0070] Based on Embodiment 1, this embodiment further optimizes the structure of the opening 3 of the pocket 2. Specifically, the opening 3 is angled, with its upper end close to the center line of the pants body 1 and its lower end away from the center line of the pants body 1, forming an angled direction from the upper inside to the lower outside; at the same time, the edge of the opening 3 is concave inward. This design is not a simple shape adjustment, but a deep integration based on ergonomics, dynamics, and usage habits. Its design principle and technical advantages are as follows: During daily activities such as walking, running, or cycling, the legs naturally swing in an adduction-extension motion, and the pocket area experiences a combined inertial force from top to bottom and from inside to outside. If the opening 3 is horizontal or vertical, items can easily slide out along the opening direction due to inertia. However, in this embodiment, the opening 3 is designed as an inclined structure with the upper end pointing inward and the lower end pointing outward, so that the opening direction forms an angle or even the opposite direction to the direction of the main inertial force, effectively preventing items from sliding out along the opening due to gravity or acceleration, significantly improving safety.

[0071] When a person is standing or walking naturally, their hand naturally slides into the pocket from the side of the body at an angle, moving from the upper outside to the lower inside. The angled opening 3 perfectly matches this operational path, allowing fingers to enter the pocket more smoothly, reducing operational resistance and achieving "seamless access." This design significantly reduces the difficulty of operation, especially when operating with one hand (such as taking out a phone while cycling).

[0072] The slanted openings better fit the cut lines of the trousers, avoiding the horizontal discontinuity caused by traditional horizontal pockets. The design, with the upper part close to the center line, makes the pockets appear more understated from the front, enhancing the overall streamlined look and style of the garment.

[0073] The opening 3 has its edges concave inward (forming a slight inward fold or inward roll structure), which allows the inner adsorption component 31 and the outer adsorption component 32 to not only achieve planar adsorption when they are attached, but also to form a local covering or nesting effect through the concave structure, increasing the adsorption contact area and alignment accuracy, and improving the pull-out resistance in the closed state, especially in violent movements, it can better resist instantaneous impact.

[0074] The combination of the sloping opening and the concave edge is not an isolated optimization, but rather forms a highly synergistic effect with the double-sided adsorption closure mechanism in Example 1: The tilted structure reduces the tendency for items to slip out, while the adsorption component provides active closing force, offering double protection; the concave edge guides finger application of force, and the low-threshold adsorption force ensures "one pull to open".

[0075] Among them, such as Figure 8 As shown, A1 represents the state before modification, and A2 represents patch 33 of this application. The edge difference between patch 33 and the state before modification is 0.3cm, giving patch 33 an arc-shaped curved blade form. This is particularly useful for the inner arc of the edge of the pocket opening of synthetic fiber fabrics, solving the opening problem without wasting time and fabric.

[0076] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
