Description

Technical Field

[0001] This application claims priority to U.S. Provisional Application No. 63 / 724,339, filed on November 24, 2024, with the title: A NON-SLIDING OFF SHOULDER BAG, the disclosure of which is hereby incorporated by reference in its entirety.

[0002] The present disclosure relates to the field of wearable carry accessories, and more particularly to shoulder bags, tote bags, or cross-body bags having anti-slip and ergonomic features to prevent strap slippage, improve user control, and / or enable convenient access during use.

Background Art

[0003] The description of the background art includes information that may be useful for understanding the present disclosure. It is not admitted that any of the information provided herein is prior art or relevant to the currently claimed invention, nor is it admitted that any of the publications specifically or implicitly referenced are prior art.

[0004] Traditionally, shoulder bags have served as one of the most common and practical forms for carrying personal items for both men and women in daily life. These bags include, for example, handbags, tote bags, cross-body bags, messenger bags, satchels, etc., and have one or more straps designed to ride on the user's shoulder so that both hands can be free during bag wearing. The concept of shoulder bags has changed little over the decades, having a pouch or container with straps that hang over the shoulder and sometimes cross the body, providing both style and functionality. The materials used for the straps vary widely, from leather, synthetic fibers, canvas to newer rubberized and polymeric materials, depending on fashion trends and functional intentions.

[0005] However, despite their widespread popularity and seemingly simple design, shoulder bags have long suffered from several functional drawbacks that negatively impact the user experience. One of the most persistent problems with traditional shoulder bags is the tendency for the shoulder strap to slip off the user's shoulder. This is particularly problematic when the user is walking, running, or simply shifting their position, causing the strap to move and often slip off completely. This problem is exacerbated when the bag is unevenly loaded or heavy, as the weight distribution makes the strap even more prone to shifting. Many users find it inconvenient, uncomfortable, and distracting to constantly adjust or reposition the strap.

[0006] The core of the slipping problem lies in the fact that conventional straps cannot properly conform to the anatomical slope and curvature of the human shoulder. Most shoulder straps are flat and rigid, or have only slight flexibility, making them unsuitable for securely staying on the contours of the shoulder, which are usually sloped. Furthermore, the inner surface of conventional shoulder straps often lacks sufficient friction against clothing materials such as cotton, polyester, and silk. The smooth surface, combined with movement and weight, easily causes the strap to slip or shift, especially when the user is wearing clothing with a smooth texture.

[0007] Another related challenge is the lack of control users experience when trying to manage the movement of their bags while walking. Because the bag swings around the user's side, there is often no easy way to stabilize or control its movement without using one or both hands. This constant movement can be irritating and disruptive to concentration, and in crowded places, it can cause the bag to bump into other people or objects, creating social inconvenience and potential danger. This swinging motion also makes it difficult to access the contents of the bag while it is on the shoulder, because the bag tends to slip away when the user tries to open it. Traditional bags usually require both hands to open and close (i.e., one hand to hold the bag and the other to operate the zipper or latch mechanism). This design flaw makes it inconvenient to quickly or carefully retrieve items, especially while multitasking or on the go.

[0008] Furthermore, current designs offer only limited solutions to improve one-handed bag operation. The fasteners, zippers, clasps, and other closure mechanisms used in most bags are either too small, too stiff, or placed in inconvenient locations that make them difficult to reach without stabilizing the bag with one hand. In situations such as walking down a crowded street, carrying other luggage, or using a phone, having to use both hands to access the bag is highly impractical.

[0009] Given the limitations of conventional shoulder bag designs—specifically, the persistent problem of straps slipping, lack of ergonomic fit on the shoulder, instability during movement, and inconvenient access mechanisms—there is a clear and urgent need for a new approach to shoulder bag construction. Solutions are needed that not only improve comfort and wearability but also enhance control, accessibility, and overall usability. Shoulder bags that better conform to the natural shape of the shoulder, prevent slippage, allow for one-handed operation, and incorporate features that help stabilize the bag during movement would significantly improve the everyday experience of carrying such a bag. [Overview of the project]

[0010] In some embodiments, this disclosure relates to an off-shoulder bag designed to improve comfort, stability, and ease of use when worn over the user's shoulder.

The description herein is not intended to be a broad overview, and therefore concepts may be simplified for clarity and conciseness. All documents referenced in this application are incorporated herein by reference in their entirety.

[0052] According to some embodiments, this disclosure relates to a non-slip shoulder bag as shown in Figures 1 to 15. For convenience of explanation, it will be understood that in this specification, “non-slip shoulder bag” may be referred to as “shoulder bag” or simply “bag.”

[0053] Referring generally to Figures 1 to 15 and the more specific drawings provided herein, exemplary embodiment 100 depicts a bag 10 comprising a bag body 101 configured to hold the user's personal belongings, such as a telephone, tablet, laptop, or other similar electronic device. The bag body 101 can be made from materials such as leather, ballistic nylon, canvas, molded polymer, or a combination thereof. These materials can be selected to provide durability, water resistance, and aesthetic appeal, depending on the user's preferences and intended use. The shoulder bag 10 includes a strap assembly 11 (shown in Figure 2) comprising at least two or more strap segments connected by a swivel joint or rivet 110 that allows angular movement between the segments.

[0054] In Embodiment 100, the strap assembly 11 includes a front strap 102, at least one padded strap (e.g., padded strap A 103) and padded strap B 105 (shown in Figure 5), at least one connecting strap 104, and a rear strap 106 joined using a press-fit rivet mechanism 110. These joints 110 allow the strap assembly 11 to conform to the natural slope of the user's shoulder, improving fit and comfort. The inner surfaces of padded strap A 103 and padded strap B 105 (shown in Figure 5) may include anti-slip materials such as rubber, silicone, or textured polymer to enhance grip on the shoulder while walking and reduce unwanted movement. Materials used for the straps may include leather, molded silicone, or reinforced flexible polymer that combines rigidity and flexibility in their structure. Furthermore, the front strap 102 and rear strap 106 are rigid enough for the strap assembly 11 to stand upright when not being worn, improving convenience when placing it down or storing it.

[0055] In Embodiment 100, the strap assembly 11 (shown in Figure 2) is shown to be connected to the bag body 101 via a pair of hinge joints 12. These hinge joints 12 can be designed to limit the outward rotation of the strap to a predetermined angle, preferably less than about 180 degrees, thereby preventing the strap from slipping off the user's shoulder. The hinge joints 12 can be fixed or modular and removable, allowing the strap assembly 11 to be removed, replaced, or reconfigured as needed.

[0056] Furthermore, to enhance control and handling of the bag 10 while walking or moving, Embodiment 100 includes a thumb hook 111 (shown in Figures 1, 2, 3, and 4) attached to the side of the bag body 101. This feature allows the user to use their thumb to secure the bag 10 in place, thereby reducing swaying and movement. The thumb hook 111 (shown in Figures 1, 2, 3, and 4) may be integrally formed, detachably attached, or retractable / foldable into a recess when not in use. Variations such as thumb loops and thumb straps are also envisioned within the scope of this disclosure. In Embodiment 100, at least two thumb hooks 111 may be provided and positioned on the side wall of the bag body 101 of the bag 10, thereby further enabling ambidextrous use and improved stability according to the user's preference, as shown in Figure 3.

[0057] The strap assembly 11, including the front strap 102 and the rear strap 106, is shown attached to one end of the bag 10. In embodiment 100, a front view of a non-slip shoulder bag having the bag body 101 is disclosed in Figure 4. The strap assembly is shown having a padded strap 103, a connecting strap 104, and a rivet 110 connecting these two parts. The hinge joint 12 is shown connecting the strap assembly to the bag body 101. The hinge joint 12 prevents the strap assembly from falling outward from the user's shoulder while the user is moving. Furthermore, the bag 10 may be equipped with a thumb hook 111.

[0058] In this embodiment, the upper part of the strap assembly 11 is shown in Figure 5. The overall components of the strap assembly 11 include a front strap 102, a padded strap A 103, a connecting strap A 104, a padded strap B 105, a rear strap 106, and four sets of rivet sets 110. Furthermore, it is shown that padded straps A 103 and B 105 are provided with anti-slip material (3031, 3051). The padded straps are configured to have anti-slip material which can be applied, for example, by adhesive, heat lamination, or sewing. In this embodiment, the same material may be used for each padded strap, or each padded strap may be made of a different anti-slip material. This anti-slip material increases friction against clothing or skin, ensuring that the straps remain securely in place on the user's shoulders while walking or otherwise moving.

[0059] The strap assembly 11 comprises multiple strap segments connected to each other, for example, via rivets 110 configured to allow limited rotational movement between adjacent segments. These rivets 110 are press-fitted or staked under sufficient pressure to provide a controlled degree of rotation, allowing the strap assembly 11 to conform to the natural incline of the user's shoulder while maintaining structural stability. The rivets 110, together with the rivet shank or body 110a, form a secure connection to fasten different segments of the strap portion together. The rivets 110 can be made of durable materials such as stainless steel, aluminum, brass, or reinforced polymer composites, and may include washers or bushings to minimize wear and enhance performance.

[0060] In Embodiment 100, the non-slip shoulder bag can be configured to adjust to various states (e.g., upright or folded), as shown in Figures 6 and 7. The hinge joint 12 functions as a connecting mechanism between the strap assembly and the bag body 101, enabling both functional mobility and structural stability. The hinge joint 12 is configured to control the angular movement of the front strap 102 and rear strap 106 relative to the bag body 101, thereby allowing the straps to be adjusted between an upright state where the straps stand independently for easy carrying on the shoulder (see Figure 6) and a folded state for compact storage (see Figure 7). Anti-slip material (3051, 3031) can be attached to the inner surface of the straps, and the front strap 102 and rear strap 106 are joined by a connecting strap 104. The use of rivet shanks 110a to join multiple strap sections is shown. Each hinge joint 12 includes a leaf section 121 that forms one of the main arms or plates of the hinge. The leaf section 121 is integrally or securely attached to the strap assembly and the bag body 101. The hinge also includes screw holes 120 / 120a for receiving screws or bolts, which are used to secure the hinge to the respective structural components using mechanical fasteners such as screws, rivets, or bolts. The joint 12 may further include a pin or pivot axis that allows for limited rotation (e.g., less than 180 degrees (DD)), thereby ensuring that the strap does not tilt excessively outward or slip off the user's shoulder. The hinge material may include an alloy, molded polymer, or fiber-reinforced composite material to provide strength and fatigue resistance under repeated operation.

[0061] Referring to Figure 8, an embodiment 100 of the configuration is shown in which the user holds the bag using their hand and strap assembly. The bag body 101 is coupled to the leaf portion 121 of the hinge joint. The strap assembly 11 maintains an upright position by its semi-rigid structure, which, in conjunction with the thumb loop, prevents the bag from slipping and allows for one-handed access. This configuration is particularly beneficial when the user is walking or moving, ensuring that the bag is always held close to the body and under control. In this embodiment, multiple thumb loops can be provided on different sides of the bag body 101 to accommodate both right-handed and left-handed users, or to provide alternative grip options.

[0062] The front strap 102, rear strap 106, connecting strap 104, pad strap A 103, and pad strap B 105 are connected to the leaf portion 121 of the bag body 101. In this embodiment, Figures 9 to 12 disclose various aspects of the hinge joint. As shown in Figures 9 to 10, a front view of the hinge joint assembly shows how the hinge securely connects the front strap 102 or rear strap 106 to the bag body 101. The hinge comprises a leaf portion 121 that functions as the main pivoting component of the hinge. A mounting plate 122 is provided as a structural insert located inside the bag body 101 and sewn or fixed, providing mechanical support and durability at the connection point. The leaf portion 121 of the hinge is attached to the strap and includes screw holes for inserting screws 120 and bolts 120a to secure the hinge to both the strap and the internal plate. This configuration allows for a secure yet rotatable connection, preventing unintended detachment or excessive rotation while allowing the strap to move within a predetermined angular range. The hinge joint 12 (shown in Figure 10) is configured to connect the straps 102 / 106 to the leaf portion 121 of the bag body 101. Furthermore, Figure 11 provides an exploded view of the hinge joint. The strap 102 is detachably coupled to the bag body 101. The leaf portion 121 is shown separated from the internal mounting plate 122. Screws 120 and bolts 120a are inserted through the leaf portion 121 and plate 122 to secure them to each other. The mounting plate 122 is made to be sized and shaped so as to be sewn or glued inside the fabric or wall of the bag body 101, ensuring a flat and secure internal fit without compromising the structural integrity of the bag or user comfort. The hinge joint is modular and detachable, allowing for replacement and reconfiguration of the strap assembly.

[0063] In this embodiment, Figure 12 discloses a hinge joint 12 equipped with a screw 120 and a bolt 120a. The hinge joint is in a low angle position, and the strap 102 is depicted in a stationary position. This configuration demonstrates that the strap can be swiveled downward by the hinge mechanism when the bag is not being worn, enabling compact storage and easy handling. The low angle of the hinge joint indicates the range of rotational movement permitted by the leaf portion 121 and the internal mounting structure while maintaining a secure connection between the strap 102 and the bag body 101.

[0064] In this embodiment, Figure 13 discloses a front view of a non-slip shoulder bag equipped with a thumb hook. The thumb hook 111 is ergonomically shaped to allow the user to use their thumb to secure and stabilize the bag while it is slung over the shoulder. The thumb hook 111 is particularly useful in preventing the bag from shaking or rotating when opening the bag with one hand. The mounting base 112 is a structural part sewn into the inside of the bag's wall and functions as an internal anchor for the thumb hook. The mounting base 112 is typically made of molded plastic or a reinforcing material such as metal and is securely sewn or bonded to the bag's lining to withstand repeated use. The connecting plate 113 connects the thumb hook 111 to the internal mount 112 and can be shaped to lie along the outer surface of the bag or recessed, thereby maintaining aesthetic appeal and minimizing the risk of snagging.

[0065] In this embodiment, Figures 14 and 15 disclose a front view and a side perspective view of a non-slip shoulder bag with a thumb loop attached. The bag body 101 is configured to include a thumb loop 131, which is a variation of a thumb hook. The thumb loop 131 is secured to the bag body using a fastening assembly. The fastening assembly may include, for example, a threaded fastener assembly, a nut and bolt assembly, or a threaded fastener assembly. In Figure 15, the bag body 101 is configured to include a thumb loop 131, which is a variation of a thumb hook. The thumb loop 131 is secured to the bag body using a fastening assembly. The fastening assembly may include, for example, a threaded fastener assembly, a nut and bolt assembly, or a threaded fastener assembly. This assembly includes a screw 120 and a bolt 120a that secure the thumb loop 131 to the bag body 101. The thumb loop 131 can be positioned on the bottom, top, or side of the bag body 101. A strap 106 is configured to connect to the bag body 101. This configuration ensures durability and resistance to mechanical stress during handling. In Figure 14 of this embodiment, the bag is shown to further include a front strap 102, a rear strap 106, and a padded strap 103 connected via an intermediate connecting strap 104 as part of a connected strap assembly. The bag also includes a thumb loop 131 and a screw 120 for securely connecting the thumb loop 131 to the bag body 101.

[0066] Figures 16-17 show an example of a simplified strap assembly 200, including a front strap 202 and a rear strap 203. These two straps are connected to each other by a single rivet 110, allowing for relative rotational movement between the straps to conform to the natural slope of the user's shoulder. Furthermore, in Figure 18, anti-slip material 2031 and another anti-slip material 2021 (※202 in the original text is interpreted as 2021) are provided on the inner surfaces of both the front strap 202 and the rear strap 203. This configuration ensures that the strap assembly stays securely in place during use, contributing to the bag's non-slip properties. In addition, rivets 110 and rivet shanks or bodies 110a are used to securely connect the front strap 202 and the rear strap 203.

[0067] In this embodiment, Figures 19 to 21 show an example of a strap assembly 300 configured to include a padded strap 303 positioned between the front strap 302 and the rear strap 304. Each strap is connected to the bag 10 as shown in Figure 19. The padded strap 303 functions as an intermediate cushioning and structural element, improving comfort and load distribution when worn on the user's shoulders. The padded strap 303 is connected to both the front strap 302 and the rear strap 304 via rivets 110 that function as swivel joints, allowing each strap to move independently and better conform to the inclination and movement of the shoulders. In addition, two or more rivets can be used depending on the user's preference.

[0068] Figures 22–23 disclose another alternative embodiment of the strap assembly 400 in which a padded strap 403 is positioned between the front strap 402 and the rear strap 404. The padded strap 403 is configured with extension ends (403a and 403b) designed to protrude laterally beyond the conventional width of the strap, thereby increasing the surface area in contact with the user's shoulder. This structural reinforcement serves to evenly distribute the weight load over a wider area of ​​the user's shoulder, thereby reducing localized pressure and improving overall comfort during use. The padded strap 403 is connected to the front and rear straps using at least one rivet 420 (shown in Figure 22) to allow rotational flexibility between components. Preferably, multiple rivets 110 (shown in Figure 23) may also be used to further improve structural strength and adjustability.

[0069] Figures 24 and 25 show another configuration in which a segmented strap assembly can be implemented to improve ergonomics and user comfort. In Figure 24, the strap assembly includes a front strap 502 and a rear strap 508 connected to each other through a series of alternately arranged padded straps and connecting straps. More specifically, the straps include a padded strap A 503, a connecting strap A 504, a padded strap B 505, a connecting strap B 506, and a padded strap C 507, arranged sequentially between the front and rear straps. Each strap is connected to another strap by multiple rivets 110. The padded straps serve to provide a cushioned, comfortable contact surface to the user's shoulders, reducing strain during prolonged use and enhancing comfort. These padded straps are preferably made of padded or soft material to conform to the contours of the user's body. The connecting straps act as flexible joint segments connecting the padded straps and the main straps, allowing for limited rotational movement. This design allows the entire strap assembly to adapt to various shoulder inclinations and movements while maintaining a secure fit and alignment. Figure 25 discloses the front portion of the strap assembly, showing the front strap 502, pad strap A 503, and connecting strap A 504. The entire strap system is connected using rivet assemblies or rotary joints 110 that provide mechanical mobility at each joint. Furthermore, the number of pad straps and connecting straps can be increased, providing greater flexibility for design customization and scalability based on user needs and application types.

[0070] In one or more embodiments of the present disclosure, the strap assembly may include a front strap and a rear strap connected by rivets, or the strap assembly may comprise a front strap, a rear strap, and one or more padded straps connected by rivets, or (as shown in Figures 19 to 20) it may include a front strap, a padded strap, and a rear strap, all connected using rivets.

[0071] Figures 26-29 show an example of a strap assembly 600 employing a molded front strap / hinge 602 via an intermediate pad 603 and connecting strap element 604. In Figure 26, the strap assembly 600 includes a front strap 602, with the intermediate pad 603 and connecting strap element 604 connected to each other by rivets 110. Recommended strap materials include moldable silicone or rubber. The padded strap 603 is formed from a relatively soft material to maximize comfort on the user's shoulder, while the molded front and rear straps 602 are rigid enough to maintain the strap assembly in an upright position when not in use. To increase structural strength, inserts of plastic or composite material can be embedded within the straps. For efficient carrying of the bag, the bag body 601 is provided with thumb hooks 611. Figures 27-29 show further details of the hinge portion. This embodiment includes elements such as straps 602a / 606a, a bag body 601, bolts 520a / 620a, and screws 520 / 620. The hinge portion includes 602b and 602c as pivot or rotation surfaces, 602d as a leaf portion, and a central pivot channel 602e which is a cylindrical or concave portion of the hinge that allows controlled movement between the strap 602 and the bag body 601.

[0072] In some embodiments, the disclosure relates to a non-slip shoulder bag having a specially constructed strap assembly 700 molded from a flexible material such as silicone or other elastomer, as shown in Figure 30. The strap assembly 700 is designed to improve comfort and stability when worn on the user's shoulder while maintaining structural integrity for support. The strap assembly 700 includes a front strap 702a and a rear strap 702d, both of which are made of a relatively rigid material so as to keep the straps upright when not in use and to maintain their shape over time. These sections provide the desired structural support and durability to the assembly as a whole. Between the front and rear straps are one or more pads 702b located on the upper surface of the straps, i.e., the area that directly contacts the user's shoulder. Connecting these pads to the structural front and rear straps is a neck section 702c that functions as a transitional flexible joint. The neck section is thinner or more flexible than the surrounding components, allowing for controlled flexibility and mobility, ensuring that the strap assembly conforms to the natural contours of the user's shoulders while resisting unwanted slipping or shifting during movement.

[0073] Figures 31 and 32 show a dual-strap configuration for a non-slip shoulder bag that improves stability and comfort during use. In this embodiment, a bag 800 having a bag body 801 is provided with two different strap assemblies: an outer strap assembly and an inner strap assembly. The outer and inner straps are attached to the bag body 801 by sewing, or by other attachment methods such as adhesive, riveting, or mechanical fasteners. This configuration allows the straps to function independently or in conjunction, depending on the user's preference and weight distribution needs. In Figure 31, the outer strap assembly includes a front strap 802 and a padded strap 803, while the inner strap assembly includes a front strap 805, a rear strap 804, and a padded strap 806 connected by rivets 820. In Figure 32, the outer strap assembly 30 is typically positioned over the shoulder to provide primary support, while the inner strap assembly 31 functions as an auxiliary stabilizing strap positioned closer to the body to prevent the bag from slipping or shifting during movement. The outer strap assembly 30 includes a front strap 802, a rear strap 804, and a padded strap 803, all connected by rivets 110. The inner strap assembly 31 includes a front strap 805, a rear strap 807, and a padded strap 806, all connected by rivets 110. This dual-strap configuration increases the contact points with the user's body, thereby reducing pressure on a single area and improving ergonomic load distribution. It also allows for versatile wearing styles, such as diagonal or over-the-shoulder, depending on the strap adjustment and wearing method.

[0074] Figures 33–37 show a mannequin holding a non-slip shoulder bag. Such a bag is shown to include a strap assembly 40 and a bag assembly 41 connected via a hinge joint 42. The bag assembly 41 includes a thumb hook 911 and a bag body 901. The hinge joint 42 allows for a versatile and ergonomic connection between the strap 902 and the bag body 901. The strap assembly 41 can be connected to the hinge joint 42 in different directions depending on the user's desired range of motion and level of comfort. The ends of the strap can be attached to the top of the hinge joint 42, allowing the strap to naturally conform to the user's shoulder. Alternatively, the strap can be connected to the side of the hinge joint 42, allowing for lateral or angled movement. In another configuration, the strap can be fixed between segments of the hinge joint 42, providing a central pivot point that allows for smooth bidirectional rotation. Regardless of the direction of connection, the hinge joint 42 is configured to restrict movement within a predetermined angular range, thereby preventing the strap 902 from slipping off the user's shoulder. As shown in Figure 37, the angle AAA between the strap and the bag is maintained at less than 180 degrees, ensuring that the bag remains in a stable position during use. This hinge-based connection system not only enhances the user experience by providing comfort and adjustability, but also adds structural integrity and adaptability to the design of the shoulder bag. The leaf section 915 is attached to the bag body 901 by a screw 920. The leaf section is configured to connect the bag body 901 to the strap 902.

[0075] Figure 38 shows an embodiment 1000 of a mannequin holding a non-slip shoulder bag with a latch mechanism in the locked position. This embodiment 1000 includes a bag assembly 51 structurally designed to accommodate a variety of personal and work tools, including but not limited to laptops, tablets, documents, and accessories. The bag assembly 51 is configured with two zippers 1020 that allow the main compartment of the bag to be fully opened, partially opened, and securely closed.

[0076] In Figure 38, the strap assembly 50 comprises a front strap 1002 and a rear strap 1006, and has a padded strap. The strap assembly 50 may include a plurality of padded straps and / or connecting straps. The bag body 1001 is configured to include two finger pockets 1030 fixed to the bag, which allow for easy gripping and handling by the user, especially when zipper operation or quick access is required.

[0077] The bag assembly 51 further incorporates a latch mechanism 53. This latch mechanism 53 allows for secure closure and easy opening of the bag. In this embodiment, the latch mechanism 53 is locked to ensure that the user's personal belongings are kept safe within the bag's compartment.

[0078] In Figure 39, the latch mechanism is in the locked state. The hook 1011 is configured to be received in a mating slot. This configuration creates a secure connection so that the user's personal belongings are kept safe within the bag body 1001. In addition, Figure 40 discloses a cross-sectional view of the latch mechanism. The latch mechanism includes a hook assembly 1011 consisting of several structural components. The hook tip 1011a is configured to engage with the mating slot 1014, in particular the slot opening 1014b. The hook shank 1011b forms an intermediate section that provides structural support and lever action between the hook tip 1011a and the hook assembly 1011. The hook base / assembly 1011 is connected to a mounting bracket 1012 which is either integrally or detachably fixed to the bag body 1001. A fastening insert 1012a is used to reinforce the connection between the hook base and the wall of the bag, thereby ensuring mechanical stability and repeated use without deformation. On the opposite side of the hook, a mating slot 1014 is formed in the flap or panel of the bag body. The slot opening 1014b receives the hook tip 1011a, and the internal cavity 1013 and internal support wall 1013a of the slot function as an engagement interface, locking the hook tip in the locked position once engaged. This latch mechanism utilizes magnetic coupling between the hook tip 1011a and the mating slot opening 1014b, enhancing closure without requiring additional manual force. This structure ensures reliable and repeatable locking engagement, allowing the user to access the bag with a simple lift or pull motion.

[0079] In Figure 41, the latch mechanism is shown in the open position, allowing free access to the bag assembly 51. The bag assembly 51 comprises a bag body 1001 that defines the main storage compartment and serves as the structural base of the bag. A pair of zippers 1020 are positioned along the top opening of the bag assembly 51, allowing for auxiliary closure or partial opening to access the stored items.

[0080] The bag further includes a front strap 1002 and a rear strap 1006, which together form a strap assembly. These straps are positioned on the shoulder side of the bag, i.e., the side that is worn over the user's shoulder, while the bag assembly side 51, corresponding to the bag body 1001, defines the non-shoulder side. This configuration provides an ergonomic orientation that allows the straps to remain securely attached to the shoulder while the latch mechanism 53 and other functional elements are accessible from the outer non-shoulder side. A thumb loop or thumb strap 1030 is integrated into the side panel of the bag body 1001. This feature allows the user to insert their thumb to stabilize the bag when it is open or in motion, especially when the latch mechanism 53 is disengaged. Thumb operation improves grip and balance, thereby reducing the need to remove the bag from the shoulder during operation.

[0081] Figure 42 discloses the hook and mating slot in a disengaged state. This non-slip shoulder bag comprises a bag assembly 51 and a strap assembly 50 connected via a leaf portion 121 of at least one hinge joint. A latch mechanism 53 is provided for securing and releasing the closing flap or opening panel. The latch mechanism 53 includes a hook assembly 1011 and a mating slot 1014. The hook assembly 1011 engages with the mating slot 1014 through a guided insertion path, thereby providing a stable and secure locking interface. A mounting bracket 1012 structurally connects the hook assembly 1011 to the bag assembly 51, ensuring mechanical reinforcement and reliable operation during repeated use. The hook 1011 and the mating slot 1014 are magnetically coupled to each other.

[0082] The illustrated embodiment shows a hook-and-slot type latch with a hook assembly 1011 and a mating slot 1014, but other latching mechanisms have also been considered. For example, latching mechanisms may include magnetic latches, hook-and-loop fasteners, spring-loaded latches, snap-fit ​​latches, mechanical clasps, or slide-locking mechanisms.

[0083] In this embodiment, Figure 43 discloses an enlarged view of the latch mechanism. The bag body 1001 forms a structural base to which the mounting bracket 1112 is fixed. The mounting bracket 1112 provides a rigid interface for supporting the hook assembly 1011, ensuring proper alignment and consistent engagement between the hook and its corresponding socket structure. The hook assembly 1011, with its hook tip 1011a, is configured to be inserted into and held within the retaining wall 1014a of the mating slot 1014. As indicated by arrow Z, the hook tip 1011a moves toward and enters the retaining wall 1014a. Once engaged, the hook tip 1011a locks into the internal region of the retaining wall 1014a, establishing a stable closed state that resists accidental disengagement due to movement or external force. The mating slot 1014 is integrated into the bag's closing panel or flap, while the internal cavity 1013 is located behind the retaining wall 1014a. The internal cavity / magnetic holder 1013 functions as a socket structure, securely seating the hook tip 1011a inserted through the retaining wall 1014a. The geometric shape of the hook-socket interface provides a secure locking engagement while allowing for quick release when the user applies an upward or downward force in the opposite direction of arrow Z.

[0084] In this embodiment, Figure 44 discloses a hook assembly 1011 in which the hook tip 1011a is securely coupled to the engagement slot 1014. The hook assembly 1011 and the engagement slot are configured to securely lock the bag body 1001, thereby preventing the bag from opening unexpectedly or the user's personal belongings from falling out unintentionally.

[0085] In this embodiment, Figure 45 discloses a perspective view of the mating slot 1014. The hook assembly 1011 includes a hook tip 1011a configured to engage with the retaining wall 1014a of the mating slot 1014. The retaining wall 1014a is shaped and dimensional to allow smooth and guided insertion of the hook tip during the locking operation and to provide secure engagement when fully seated. As shown, the dimension PP of the retaining wall 1014a is greater than the dimension QQ, forming a widened or tapered opening that facilitates alignment and guided insertion of the hook assembly 1011 when closed. Similarly, the internal dimension SS of the mating slot 1014 is greater than the dimension RR, which allows the hook tip to seat firmly within the cavity of the slot, improving the locking strength and stability of the latch mechanism.

[0086] In this embodiment, Figure 46 discloses a locked hook assembly 1011 coupled to the bag body 1001. Furthermore, Figure 47 discloses a cross-sectional view of the hook and the fitting slot. Figure 47 shows the hook assembly 1011, the hook tip 1011a, the bag body 1001, the mounting bracket 1013, the magnetic pocket 1013b, the fitting slot 1014, the mounting bracket 1012, the magnetic pocket 1012b, and the magnet 1015.

[0087] Figure 48 discloses an exploded view of the hook assembly 1011. The hook assembly 1011 is supported and fixed to the bag body 1001 via a mounting bracket 1012 having a boss 1012a. The boss 1012a passes through a hole 1001a in the bag and fits snugly into a recess 1011b of the hook assembly 1011. A magnet 1015, located in the magnetic pocket 1012b, is also used by the assembly 1011.

[0088] Figure 49 discloses an exploded view of a latch mechanism with a hook assembly and a mating slot. The hook assembly 1011 is configured with a hook tip 1011a attached to the bag body 1001. A mounting bracket 1012 having a mating boss 1012a is used. The mating boss 1012a passes through a hole in the bag 1001 and fits snugly into the recess 1011b.

[0089] Figure 50 shows an example of the interaction between the hook socket 1014, the bag body 1001, and the mounting bracket 1013. The hook socket 1014 is formed to have a main slot opening 1014a and an internal retaining wall 1014b. The main slot opening 1014a allows for insertion while guiding the hook tip during the closing operation, while the internal retaining wall 1014b provides a structural stopper to ensure the hook remains securely engaged when fully inserted. The mounting bracket 1013 is positioned behind the hook socket 1014 and has the function of enhancing the locking engagement via magnetic attraction. It includes a front magnetic seat 1013a configured to align with the main slot opening 1014a and a magnetic pocket 1013b through which the mounting bracket 1013, the bag hole 1001a, and the hook socket 1014 are fastened.

[0090] Figure 51 shows the front magnet seat 1013a which connects to the internal retaining wall 1014b formed in the main slot opening 1014a. The front magnet seat 1013a protrudes outward from the mounting bracket 1013 and provides a precisely molded alignment function that securely fits within the internal retaining wall 1014b of the hook socket 1014. The hole 1001a in the bag body 1001 is the area where these two parts connect.

[0091] Figure 52 shows a perspective view of a shoulder bag inverted, similar to the shoulder bag in Figure 42. The bag body 1001 forms the main structure of the bag and is fitted with a bag handle or shoulder strap, which includes a front strap 1002 and a rear strap 1006 for carrying. This assembly further includes padded straps A 1003, B 1005, and connecting straps 1004 connected to the bag body via a hinge joint leaf portion 121, which allows for ergonomic swivel and conformity to the user's shoulder. A pair of zippers 1020 are positioned along the opening of the bag body 1001 to ensure secure closure of the main compartment. At the bottom of the bag, the bottom insert features a slot 1050b and eight rivets 1060. The slot 1050b is set to a specific size and position to accommodate one or more fingers of the user, allowing the user to firmly grip and stabilize the bag when retrieving contents or during transport. The bottom component 1001c is used as an additional protective layer to help securely hold items inside the bag.

[0092] Figures 53 and 54 show the bottom of the shoulder bag from different viewpoints. The bottom insert 1050 has a finger pocket 1050a on the bag body 1101. For example, eight rivets 1060 (1060x8) can be used. A slot 1050b is located within the bottom insert 1050, allowing the user to securely grip the bag with their fingers, improving control and stability during handling. A pair of projections 1050c extend upward from the bottom insert 1050, defining a retaining area that restricts the movement of flat objects placed inside the bag, such as laptops, electronic tablets, or other similar items, preventing lateral or vertical slippage. In addition, the bottom insert 1050 includes a curved cutout 1050d molded to fit the user's body, improving comfort when the bag is carried on the shoulder or held against the torso. The bottom insert 1050 is secured by eight rivets 1060. The bottom insert 1050 includes the bottom member 1001c of the bag body (shown in Figure 53). Note that there may be two or more protrusions, and they can take on various shapes and geometric structures.

[0093] In this embodiment, Figure 55 discloses how the user's thumb is engaged to hold the bag so that it does not tilt while the user is moving. The bag straps 1002 / 1006 are attached to the bag body 1001. In addition, the zipper 1020 prevents the user's personal belongings from falling out. The thumb loop 1030 is configured to allow the user to use their thumb to stabilize and hold the bag while the bag is slung over the shoulder. The thumb loop 1030 is retractable, foldable, or integrally formed with the bag body 1001 so that it can be compactly stored when not in use. In this embodiment, a thumb strap or thumb hook may also be used instead of the thumb loop.

[0094] In this embodiment, Figures 56-58 disclose perspective views of a user / mannequin holding the shoulder bag. The bottom insert 1050 (shown in Figures 56 and 58) is integrated into the bag body 1001 and works in conjunction with extensions 1001a / 1001cd, which serve to provide stability and support for the stored items. The combination of the finger pocket 1050a, thumb slots 1050b / 1050f, and extensions 1001a ensures that personal belongings are securely positioned and minimizes lateral or vertical movement when the bag is carried.
