Description

Technology Field

[0001] The present invention relates to a bag, and more specifically, to a bag comprising a shaking prevention structure capable of preventing the bag worn on the back from shaking excessively from side to side during exercise. Background Technology

[0002] Generally, bags are widely used by various users, such as students, office workers, and travelers, as a means of storing and carrying items; in particular, the backpack type, designed to be worn on both shoulders, has established itself as the most popular structure. Backpacks are highly practical because they are worn close to the user's back, causing minimal strain even during prolonged use, and allow for the freedom of both hands. However, as the wearer's walking or activity speed increases, the backpack's ability to secure the bag reaches its limit.

[0003] Recently, with the rise in outdoor and fitness activities, there has been an increasing demand for backpacks that can be used during strenuous workouts such as hiking, running, and cycling. However, conventional backpacks are designed to be secured to the wearer's body solely by shoulder straps, which frequently causes the bag to sway from side to side when moving quickly or rotating the body. This hinders the wearer from maintaining balance and leads to problems such as reduced athletic performance and distraction.

[0004] The issue of a bag swaying from side to side is not merely an inconvenience but is directly linked to safety. For example, if a bag continuously shakes while running or cycling, it can disrupt the user's sense of balance, increasing the risk of falls; this poses a particularly greater risk factor for adolescents and the elderly. This structural problem suggests that existing backpacks have not adequately considered the exercise environment.

[0005] Items stored inside the bag are also affected by shaking. If the bag shakes excessively from side to side or up and down, items inside frequently collide, increasing the risk of damage to sensitive items. Furthermore, if the zipper or Velcro at the top opening is not fully closed, items may be flung out due to the shaking. This issue can lead to serious situations, such as the loss or theft of personal belongings during outdoor activities.

[0006] While some existing backpack designs have attempted to attach a waist belt in addition to the shoulder straps, these methods suffered from drawbacks, such as the belt not being manufactured as a single integrated unit or easily slipping out of its fixed position. Furthermore, most waist belts are designed to support only the lower body, limiting their ability to effectively control upper body movement. Consequently, wearers frequently complain of discomfort caused by upper vibrations even while wearing the waist belt.

[0007] In other conventional technologies, methods have been proposed to secure the back panel to the user's body using Velcro or fastening devices; however, these methods had structural defects, such as difficulty in adjusting the position to suit the user's physical condition and causing discomfort due to skin pressure or friction during prolonged wear. In particular, as the load of the bag increases, the pressure applied to the fastening parts increases, resulting in a counterproductive effect that actually restricts the wearer's movement during exercise.

[0008] Conventional structures also present a problem in that they are difficult to adapt flexibly to the user's body type. Despite the existence of users with diverse body types—such as men, women, adults, and children—a structure that provides the same fixing force at the same position is inherently inefficient. Unless a structure is provided that allows for individual adjustment of the fixing position or fine-tuning of the tightening strength, the effectiveness of the anti-shake function is limited.

[0009] Some products have attempted to mitigate shaking by applying band-type elastic straps; however, structurally, this often causes discomfort as it acts to compress the wearer's chest or abdomen. Furthermore, problems frequently occurred where the strap lost its elasticity and function when kept tensed for an extended period, or slipped off during activity. Structural improvements are necessary to address these issues, as the strap's performance is inconsistent depending on changes in the user's body shape or usage environment.

[0010] One of the problems with existing backpack structures is that tightening force and position adjustment are not separated. Most backpacks are designed with securing straps that perform only a single function, which entails the inconvenience of requiring the user to manually operate the strap in multiple steps using both hands to fasten or unfasten it. This is particularly problematic when the tightness needs to be adjusted mid-activity, as it is either impossible or requires considerable hassle.

[0011] Ultimately, conventional bag structures share a common problem: they lack a multi-layered, organic design to fundamentally control shaking. Existing methods, consisting of simple shoulder straps, fixing belts, and elastic bands, operate with each element functioning independently; they fail to provide a structure that interlocks or responds in real-time to the wearer's body shape and movements. Consequently, they are unable to effectively suppress shaking in various situations, resulting in unsatisfactory outcomes in terms of protecting contents and user convenience.

[0012] The present invention aims to solve the problems of the conventional technology. By providing a tightening structure capable of interlocking at the upper and lower sections, respectively, and a guide structure capable of position adjustment, the present invention is designed to allow for the customized application of an anti-shake function according to the wearer's body type and exercise style. Through this, it seeks to fundamentally resolve issues such as instability, discomfort, and damage to stored items that occur in conventional backpack structures. Prior art literature

[0013] Korean Patent Publication No. 10-2042630 (Registration Date: November 04, 2019) The problem to be solved

[0014] Conventional backpacks are structured to be secured to the wearer's back solely by shoulder straps, which causes the storage body to shake violently from side to side or up and down when the wearer walks or runs, thereby hindering walking and causing damage or loss of stored items. Furthermore, users experience significant inconvenience because the securing position cannot be adjusted to fit the body shape or the tightening strength cannot be controlled. To solve the above problems, the present invention aims to provide a bag that includes an anti-shake structure that guides the storage body of the bag to be securely attached to the wearer's back and torso and is adjustable according to the body shape. means of solving the problem

[0015] A bag according to one aspect of the present invention for achieving such an objective may comprise: a storage body portion forming a storage space capable of accommodating items from an upper opening; a shoulder wearing portion mounted on one side of the storage body portion and guiding the storage body portion to be worn on both shoulders of the wearer so as to be in close contact with the wearer's back; and an anti-shake portion mounted in a manner that wraps around a portion of the outer surface of the storage body portion in a horizontal direction, has a structure extending to the left and right sides, and is fastened in a manner that wraps around a portion of the wearer's torso to secure the storage body portion to the wearer's back.

[0016] In one embodiment of the present invention, the anti-shake member may be configured to include: a wire rope structure extending in a horizontal direction to wrap around the central part of the storage main body and extending in both directions by a predetermined length, and an upper tightening wire connected to a lower tightening wire at both ends; and a wire rope structure extending in a horizontal direction to wrap around the lower part of the storage main body and extending in both directions by a predetermined length, and a lower tightening wire connected to an upper tightening wire at both ends.

[0017] In one embodiment of the present invention, the anti-shake member may be configured to include: an upper guide having a ring structure that is mounted in plurality at a predetermined distance in the horizontal direction from the center of the storage main body and fixes the vertical position of the upper tightening wire while allowing sliding movement in the left and right directions; and a lower guide having a ring structure that is mounted in plurality at a predetermined distance in the horizontal direction from the lower part of the storage main body and fixes the vertical position of the lower tightening wire while allowing sliding movement in the left and right directions.

[0018] In one embodiment of the present invention, the anti-shake member may be configured to include a tightening fixing member having a structure that is symmetrically mounted at both ends where the upper tightening wire and the lower tightening wire are connected, and which tightens and fixes the upper tightening wire and the lower tightening wire by pulling them toward the sternum of the bag wearer.

[0019] In this case, the upper guide may be structured to be fixed by adjusting its height according to the wearer's body type and intention.

[0020] In addition, the lower guide may be structured to be fixed by adjusting its height according to the wearer's body type and intention. Effects of the invention

[0021] According to the present invention, an anti-shake unit is provided to secure the storage body to the wearer's back, thereby minimizing the shaking of the bag from side to side or up and down during exercise. The upper and lower tightening wires are designed to interlock with each other to stably wrap around the wearer's torso, and the wearer can easily adjust the tightening strength and secure the bag from the front through a tightening fixing member provided at the connection point. Furthermore, the upper and lower guides are structured to allow sliding while also being fixed, allowing for height adjustment to fit the user's body type, thereby improving user convenience. This structure can flexibly adapt to various body types and exercise environments, preventing the bag from shaking while enabling stable storage of contents. Moreover, by simultaneously ensuring adjustability and fixing power without interfering with the wearer's exercise movements, the comfort and functionality of wearing the bag can be maximized.

Specific details for implementing the invention

[0023] Preferred embodiments of the present invention will be described in detail below with reference to the drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the present invention.

[0024] Throughout this specification, when it is stated that one component is located "on" another component, this includes not only cases where one component is in contact with another component, but also cases where another component exists between the two components. Throughout this specification, when it is stated that a part "includes" a component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0025] FIG. 1 shows a front view of a bag according to one embodiment of the present invention, and FIG. 2 shows a rear view of a bag according to one embodiment of the present invention.

[0026] Referring to these drawings, the bag (100) according to the present embodiment is equipped with a storage body part (110) of a specific structure, a shoulder wearing part (120), and an anti-shake part (130), so that the position and tightness of the anti-shake part (130) can be customized according to the wearer's body type and intention, and the bag worn on the back can be prevented from shaking even during exercise, and ultimately, the wearer can be encouraged to exercise smoothly and the storage condition of the contents inside the bag can be stably guaranteed.

[0027] Hereinafter, each component constituting the bag (100) according to the present embodiment will be described in detail with reference to the drawings illustrated in FIGS. 1 to 6.

[0028] Detailed description of the storage main body (110)

[0029] The storage body (110) is a central structure of the bag of the present invention and forms an internal storage space for accommodating various items. The storage space is configured to be openable and closable through an upper opening, and the shape and size of the opening are adjusted so that the user can easily put items in and take them out. This storage body can be designed with a general rectangular or curved shape and is designed to be positioned at the center of the user's back when the bag is worn.

[0030] The storage body (110) forms the outer shell of the entire bag and is made of a material that can simultaneously ensure durability and lightness. For example, nylon or high-strength polyester fibers may be used, and the contents can be protected from the external environment by applying a waterproof and stain-resistant fabric. The interior is equipped with at least one detachable pocket or band structure so that various items such as electronic devices, documents, and clothing can be stored separately and securely.

[0031] The storage main body (110) includes various fixing parts or through holes so that components of the anti-shake part (130) can be attached to the outer surface. Since the upper tightening wire and the lower tightening wire are designed to wrap around the outside of the main body, corresponding guide parts are arranged at appropriate intervals in the horizontal direction. The outer surface of the main body may be reinforced with additional reinforcing patches or friction-reducing materials to withstand the friction of the wires.

[0032] This storage body can also improve comfort by including cushioning material or a mesh-based breathable material on the back, which comes into close contact with the wearer's back. Particularly since body temperature rise and sweat wicking must be considered during strenuous exercise such as running or cycling, the back of the body may include an air channel structure that facilitates sweat wicking or maintains breathability. This allows the wearer to remain comfortable even during prolonged use.

[0033] Additionally, an external pocket, auxiliary storage space, or bottle holder may be added to the bottom or side of the storage body, and additional functions such as a USB port, locking mechanism, or reflective strip may be included as needed. In particular, since the present invention emphasizes the suppression of shaking and the tight seal of the storage body, it is preferable that the external structure be configured in a streamlined shape to form a sense of unity with the body without unnecessary protrusions.

[0034] Detailed description of the shoulder-mounted part (120)

[0035] The shoulder-mounted portion (120) is connected to both upper sides of the storage body (110) and is draped over both shoulders of the user, thereby serving to secure the bag to the wearer's back. Similar to a standard backpack, the shoulder-mounted portion of the present invention is manufactured with a structure that includes pads, designed so as not to cause pressure or pain even when worn for a long time. The length of the portion includes a length-adjusting buckle or slide adjuster that can be adjusted to fit the wearer's body.

[0036] The interior of the shoulder wearing part (120) is designed with a curved structure that is ergonomically designed, so that it naturally adheres to the shoulder line. This prevents the shoulder strap from slipping or twisting depending on the wearer's body shape and also performs the function of maximizing weight distribution. In particular, since the wearing part must be connected to form a sense of unity with the back panel in conjunction with suppressing the shaking of the storage body, the lengths on both sides can be independently adjusted so that it can be mounted evenly on both shoulders without losing its center of gravity.

[0037] The lower part of the shoulder strap (120) is connected to an extended position with the upper part of the storage body and can be configured to be indirectly connected to the upper tightening wire (131). For example, the shoulder strap and the upper tightening wire may be combined into a single interlocking structure to provide fixing force simultaneously when worn, or an interlocking mechanism may be adopted in which the upper tightening wire is tightened together when the wearer pulls the shoulder strap. Such a structure simplifies the wearer's movements and helps to use the anti-shake function more intuitively.

[0038] The shoulder straps contain an internal high-elasticity sponge or porous filler to provide cushioning when worn, while the exterior finish is treated with waterproof and highly durable fabric to prevent wear in harsh outdoor environments. Additionally, small pockets for storing personal items, hook holders, or reflective materials may be added to the outer surface of the shoulder straps. This serves to ensure visibility during nighttime activities or enhance user convenience.

[0039] Furthermore, the shoulder-mounted portion (120) may be provided with a fastening portion near the center so that it can be used together with a chest connecting strap. This fastening portion forms a structure that can further strengthen the suppression of vertical shaking by linking with a tightening fixing member (135) or another chest strap, and can provide high stability, especially to users engaged in vigorous activities. Overall, the shoulder-mounted portion is an important component that stably supports the storage body and simultaneously works organically with the anti-shake portion to enhance the wearing comfort.

[0040] Detailed description of the anti-vibration part (130)

[0041] The anti-shake unit (130) is a component that performs the core function of the present invention and serves to suppress left-right and up-down shaking by fixing the storage main body (110) so that it adheres closely to the wearer's torso. This anti-shake unit includes an upper tightening wire (131) and a lower tightening wire (132) extending in the horizontal direction, an upper guide (133) and a lower guide (134) that guide and support them, and a tightening fixing member (135) that tightens and fixes the wires. This configuration provides stable fixing force by simultaneously wrapping the wearer's torso at two points, upper and lower.

[0042] The upper tightening wire (131) extends horizontally along the outer side of the central part of the storage body and is configured to protrude to the left and right for a predetermined length, wrapping around the body above the user's chest. This upper tightening wire is made of a synthetic wire or strap material that is flexible yet maintains elasticity, so that it can maintain a constant tension according to the wearer's movements. The lower tightening wire (132) is arranged in a similar structure along the outer side of the lower part of the storage body and, like the upper tightening wire, extends to the left and right to wrap around the wearer's abdomen or solar plexus area.

[0043] These wires can be connected to each other at each end to form a single loop, and a tightening fixing member (135) is installed at the connection point. The tightening fixing member is designed to be positioned on the front of the wearer, for example, near the solar plexus, and includes a tightening handle or a sliding fixing device that the wearer can easily operate with both hands. The wearer sets the tightening strength by pulling or pushing to adjust the length of the wire, and the position is automatically fixed by the fixing member.

[0044] The wire is inserted along the upper guide (133) and lower guide (134) installed on the outer surface of the storage body, and each guide is manufactured in a loop shape to guide the wire's position in the horizontal direction and prevent it from deviating in the vertical direction. These guides are arranged in multiple numbers at predetermined intervals in the horizontal direction, allowing the wire to slide left and right and naturally align to fit the wearer's body shape. In particular, the upper and lower guides can be adjusted in height according to the user's body shape and wearing position, thereby providing a customized fit.

[0045] As a result, the anti-shake unit (130) does not simply pull the storage body with a strap, but rather organically closes it at two points, upper and lower, and through a structure that can actively respond to the wearer's movements, it fundamentally solves the problems of shaking, discomfort, and uneven wearing that occurred in conventional bags. This structure minimizes shaking of the bag even during vigorous exercise or walking for a long time, thereby providing the user with a stable and comfortable wearing experience.

[0046] Detailed description of the upper clamping wire (131)

[0047] The upper tightening wire (131) is a key fixing member constituting the anti-shake part (130), extending horizontally along the outer side of the central part of the storage main body (110) and forming a structure that wraps across the upper chest of the wearer. The upper tightening wire (131) is formed to protrude a certain length or more to both the left and right sides to wrap around the wearer's chest area, and is designed to allow for close adjustment according to the wearer's movements or body shape. This tightening structure effectively controls the bag from shaking up and down or left and right.

[0048] The upper tightening wire (131) is generally made of a material that possesses both flexibility and resilience. For example, a metal cable with a nylon coating, a reinforced plastic wire, or a high-elasticity synthetic fiber (e.g., Kevlar, Dyneema, etc.) may be used, and a thin iron core or tension band is inserted inside the wire to maintain constant tension. This structure ensures that there is no loss of tension even during repeated tightening and releasing operations, and prevents the wire from losing elasticity or breaking.

[0049] The middle portion of the upper tightening wire (131) passes through a plurality of upper guides (133) mounted on the outer side of the storage main body. These upper guides are formed as loop-shaped or sliding guide structures, allowing the wire to slide left and right while fixing it so that it does not move in the up and down direction. Through this, even if the wearer moves, the position of the tightening wire does not deviate, and a tightening effect suitable for the body shape can be provided at a consistent position.

[0050] Both ends of the upper tightening wire (131) are connected to both ends of the lower tightening wire (132), and a tightening fixing member (135) is positioned at this connection point. The user can tighten or loosen both wires simultaneously by pulling the tightening fixing member located on the front of the bag, for example, near the solar plexus. In particular, since the upper tightening wire is designed to cross the chest, the storage body adheres firmly to the upper part of the wearer's upper body, and can effectively suppress upper shaking even during vigorous movements.

[0051] As an example of actual application, the upper tightening wire (131) is useful in high-motion environments such as running, cycling, and hiking. When the user tightens the upper tightening wire after wearing it, the storage body is firmly attached to the upper chest, so that shaking of the upper body is not directly transmitted to the bag. This minimizes the shaking of the upper chest or swaying from side to side that commonly occurs in conventional bags, and has the effect of protecting the contents and reducing fatigue of the wearer.

[0052] Detailed description of the lower clamping wire (132)

[0053] The lower tightening wire (132), like the upper tightening wire (131), is one of the core components of the anti-shake part (130), extends horizontally along the lower outer side of the storage body part (110), and forms a structure that wraps around the wearer's abdomen or the area below the sternum. The lower tightening wire forms a binding structure with the upper tightening wire and secures the wearer's torso in a double upper and lower manner, thereby preventing the bag from tilting forward or imbalance caused by load transfer.

[0054] The lower tightening wire (132) is made of the same or similar material as the upper tightening wire, and adopts a high-elasticity synthetic material, a metal core cable, or a tension band insertion structure to stably maintain tension even with repeated use. The lower tightening wire is designed with appropriate thickness and elasticity ratio so as not to particularly compress the abdomen or waist area, and it is desirable to wrap it with a flexible covering material so that it responds elastically to movement.

[0055] The lower tightening wire (132) passes along a plurality of lower guides (134) arranged at regular intervals in the lower part of the storage main body, and these guides are also formed with a loop-shaped sliding structure. The lower guides maintain the horizontal arrangement of the lower tightening wire and allow it to be automatically adjusted to fit the wearer's body shape through the left and right sliding of the wire. The above structure enables the wire to be arranged in a customized manner according to the user's waist position or pelvic shape.

[0056] Both ends of the lower tightening wire (132) are connected to the same tightening fixing member (135) as both ends of the upper tightening wire, and are configured so that the user can pull or push the wire from the front to fix it. As a result, the upper and lower wires are adjusted simultaneously, and the wearer can secure a tight fit over the entire torso with a single movement. In particular, the lower tightening wire firmly grips the lower part of the storage body at the abdomen or below the solar plexus, so that the storage body can be prevented from bouncing up or tilting downwards during walking or jumping.

[0057] The lower tightening wire (132) is particularly effective in environments requiring high activity, such as hiking backpacks, military backpacks, and aerobic training backpacks. For example, in exercises involving many rotations or jumping movements centered on the lower body, the storage body often tilts downward, but the lower tightening wire firmly secures it between the abdomen and the back, integrating the storage with the user's center of gravity. This plays an important role in preventing back pain or loss of balance, as well as improving exercise efficiency.

[0058] Detailed description of the upper guide (133)

[0059] The upper guide (133) is composed of a ring-shaped member that supports the upper tightening wire (131) so that it can extend stably in a horizontal direction along the outside of the storage body (110). The upper guide is installed on the outer side of the central part of the storage body and is positioned to be in close contact with the flat surface without protruding toward the back panel of the bag. Through this, it serves to guide the wire so that it does not deviate from its position without causing discomfort to the user's back.

[0060] The upper guide (133) is generally formed of a durable synthetic resin, high-strength silicone, or metal and includes a through hole or groove structure into which a wire can be inserted in the horizontal direction. Each guide is installed at multiple locations at regular intervals in the horizontal direction, allowing the wire to move freely along the guides. As a result, the wire is provided with the flexibility to slide naturally left and right according to the wearer's body shape or movement.

[0061] The most significant feature of the upper guide (133) is its structure, which allows the wire to slide left and right but prevents it from moving up and down. To this end, ribs or seating grooves are formed inside the guide to prevent the wire from moving vertically, and a surface treatment is applied to the outside of the guide to account for friction so that the wire can be kept fixed. In some embodiments, the wire may be configured to be fixed by an external clip structure rather than passing through the inside of the guide.

[0062] The upper guide can also be implemented with a height-adjustable structure. Considering situations where the position of the upper tightening wire needs to be adjusted according to the user's body type or shoulder height, it is possible to form a vertical guide slot in the storage body and configure the upper guide so that it can be moved up and down along the slot and secured with a screw or snap. This allows the fixing position of the upper tightening wire to be customized for the user.

[0063] As a practical application example, the upper guide allows the tightening wire to be held firmly near the chest to suppress upper body swaying during running, and prevents the wire from lifting or coming off even during vigorous movements. Additionally, since the upper guides are placed at regular intervals, the wire wraps around the torso with even pressure, maintaining consistency in tightening and reducing discomfort for the wearer.

[0064] Detailed description of the lower guide (134)

[0065] The lower guide (134) is a component that supports and guides the lower tightening wire (132) so that it can extend stably in a horizontal direction along the lower outer side of the storage body (110). Similar to the upper guide, the lower guide is distributed at multiple locations in a horizontal direction and is mounted to be in close contact with the lower outer surface of the bag. This ensures that the position of the lower tightening wire remains fixed even if the wearer repeats movements during exercise, and contributes to providing appropriate contact force to the wearer's abdomen.

[0066] The lower guide (134) is made of a highly durable synthetic resin, silicone, or aluminum alloy and includes a through hole, groove, or guide channel inside so that the lower tightening wire is inserted along a specific path. Friction reduction treatment is applied so that the lower tightening wire can slide in the left and right directions, and helps to prevent the wire from stretching asymmetrically or shifting when the user wears it. The end of the lower guide may include a hook structure or a protruding rib to prevent the wire from coming off.

[0067] The most important function of the lower guide (134) is to prevent vertical deviation while maintaining uniform tension of the wire according to the wearer's movement. To this end, the inside of the guide is designed with a curved surface that maintains a relatively tight space without interfering with the elasticity of the wire. It is configured so that movement in the left and right directions is easy, but deviation or sagging does not occur in the up and down directions.

[0068] The lower guide can also be designed with a structure that allows for height adjustment to suit the wearer's body shape. A vertical adjustment groove or slot is formed at the bottom of the storage body, and the lower guide is designed to move up and down along this slot and be fixed in the desired position using an adjustment fastener or button. This allows the wearer to freely adjust the height of the wire according to their waist height or abdominal thickness.

[0069] In a practical application example, during hiking, when there is frequent movement of the waist or lifting of the lower body, the lower guide secures the lower tightening wire near the waist to prevent the bag from tilting downwards. Additionally, as multiple lower guides are evenly distributed, the wire provides a tight grip without twisting in the horizontal direction, thereby effectively suppressing shaking of the bottom of the storage body.

[0070] Detailed explanation of the clamping fixing member (135)

[0071] The tightening fixing member (135) is a structure for adjustment and fixation that connects both ends of the upper tightening wire (131) and the lower tightening wire (132) to allow the two wires to be pulled and tightened simultaneously from the front of the user's torso. This component is generally designed to be located near the wearer's solar plexus or the center of the abdomen and is positioned so that the user can easily operate it with both hands. By integrally adjusting the two wires, the tightening fixing member enhances the convenience of wearing and allows for the intuitive use of the anti-shake function.

[0072] The tightening fixing member (135) includes a tightening adjustment mechanism that can finely adjust the length of the wire and a fixing mechanism that can maintain the state in which the user pulls. For example, a one-touch slide lock, a cam lock structure, or a rotary roller clamp method may be used, and it is automatically fixed when the user pulls with a certain force and can be released by operating a button or release lever. This structure allows the tightening force to be set more quickly and precisely than the conventional strap method.

[0073] The clamping fixing member is externally compact and designed to closely adhere to the user's abdomen, ensuring no foreign body sensation during wear. Additionally, the exterior finish is made of soft plastic, rubber, or fabric to prevent pain caused by pressure or friction, even during prolonged use. Internally, guide rollers or sleeves may be embedded to minimize friction between the upper and lower wires, and a structure featuring independent channels is also applied to prevent the two wires from twisting.

[0074] The tightening fixing member (135) is designed with a structure that can control the upper and lower wires in conjunction, thereby having the advantage of tightening or loosening the wearer's chest and abdomen simultaneously with a single motion. This structure saves time and motion compared to conventional individual tightening structures and helps maintain the balance of tightening strength, so that the bag does not tilt to one side and remains centered. It provides great convenience, especially when it needs to be fastened or unfastened quickly during outdoor activities.

[0075] In a practical example, when a user adjusts the upper and lower wires using the clamping mechanism, the main body of the device adheres closely to the wearer's back in both upward and downward directions, thereby suppressing both upper body and abdominal swaying during exercise. Since the clamping mechanism is designed to centrally regulate the overall clamping force, it maintains consistency in the user experience and ensures the same wearing effect across various body types and environments.

[0076] Three embodiments regarding the height adjustment structure of the upper guide (133) and the lower guide (134)

[0077] Example 1: Belt-type adjustment slot and multi-position fixing structure

[0078] The first embodiment is a method of determining a fixed position by forming a plurality of fixed slots or belt loops at regular intervals on the outer surface of the storage body (110), and attaching hook or button-shaped protrusions to the rear surfaces of the upper guide (133) and lower guide (134) and inserting and fastening them into slots of a desired height. This structure has the advantage of allowing position adjustment through simple fastening without a complex mechanism and simplifying the manufacturing process.

[0079] The above fixed slots are formed in multiple numbers along the vertical direction at intervals of 2 to 4 cm, and each slot is a loop-shaped structure made of reinforced fabric or webbing belt material. The upper guide and lower guide have a latch-type fastening projection or a plastic clip protruding that can be inserted into this loop, so that the user can set the height of the guide by attaching it to a loop at a desired position.

[0080] This method is easy to manufacture due to its simple structure and small number of parts, and it has the advantages of being lightweight, having fewer breakdowns. Additionally, precise height adjustment is possible depending on the number and spacing of the loops, and flexible settings can be adjusted according to changes in the wearer's body shape or purpose of use. Since the guide section through which the wire passes is precisely fixed in a fixed position, shaking or sagging can also be prevented.

[0081] As a practical example, if the wearer has a thick abdomen or a high waist, the lower guide can be installed in the upper slot to wrap the wire at a high position. Conversely, for those with a low waist or large chest, the upper guide can be installed in the lower slot to achieve a natural, snug fit. This method can be efficiently utilized in environments where multiple users must share the same product, such as schools or the military.

[0082] This embodiment allows the user to easily disassemble and assemble it without tools, making it advantageous for maintenance or replacement. Additionally, when changing the position while wearing, the method involves removing the guide from one loop and reattaching it to another loop, making it intuitive and easy to repeat. Since there are no separate sliding parts, the production cost is low and the durability is excellent.

[0083] Example 2: Vertical slot insertion and Velcro fastening method

[0084] The second embodiment is a method in which the fixing parts of the upper guide (133) and the lower guide (134) are inserted into a slit-shaped pocket or sliding slot formed vertically on the outer side of the storage body, and the position is fixed at a desired height using Velcro. Velcro has the advantages of being easy to fasten, having strong fixing power, and allowing for flexible position adjustment, making it suitable for accommodating various body types and movements.

[0085] Inside the slot, one side of Velcro (e.g., the hook side) is continuously attached in a vertical direction, and the opposing side (the loop side) of Velcro is also attached to the rear of the upper or lower guide, so that when the user slides the guide up and down and presses it at the desired position, it is fixed in that location. The slot can be formed on the outer surface of the storage body by sewing or compression.

[0086] The advantage of this method is that it allows for fine height adjustment. While the first embodiment offers stepwise (slot-unit) adjustment, this method enables continuous adjustment, allowing for more precise adaptation to the user's body shape. In particular, wearer satisfaction is high because the position can be finely set based on waist height, back curvature, and chest protrusion.

[0087] The slot and Velcro structure makes it convenient to adjust the position directly while wearing the bag. With the bag on, the wearer can adjust the position by reaching behind their back and sliding the guide up and down, or simply by pressing with a finger to secure it. In particular, it allows for easy real-time adjustment even if the bag lifts or sags during movement.

[0088] As a practical application example, if the upper tightening wire moves upward and causes discomfort due to body posture changes such as leaning forward while cycling, the upper guide can be readjusted to the lower part within the slot so that the wire is positioned at the bottom of the chest. The Velcro provides sufficient fastening force in normal usage environments and offers great user convenience as it can be easily detached when replacement or washing is required.

[0089] Example 3: Toothed snap button attachment method

[0090] The third embodiment is a method of selecting a fixed position by forming a toothed fixed rail or a spaced multi-stage arrangement of snap buttons on the outer side of the storage body and snapping them together with means corresponding to the upper guide (133) and the lower guide (134). This structure is mechanically securely fixed and provides a strong fixing structure that remains stable without shaking once fastened.

[0091] The above-mentioned fixed rail is formed with protruding snap buttons or an interlocking tooth structure at regular intervals, and a clip structure or female snap is attached to the joint between the upper and lower guides to be pressed and inserted. The user can move the guide position vertically and press it to secure it by aligning it with the snap at the desired position. This method provides a tactile click, allowing the user to accurately verify whether the connection is secure.

[0092] This structure is particularly advantageous in environments requiring long-term fixation. For instance, in long-distance trekking, military backpacks, and rescue backpacks, where consistent tightening force is critical, a design where snap buttons do not easily loosen under external force is a significant advantage. Furthermore, this method is suitable for long-term use after a single fixation, rather than for repeatedly adjusting the height.

[0093] Snap buttons are made of metal or reinforced plastic, and if corrosion-resistant materials are used, they operate without issues even in outdoor environments. During manufacturing, snaps are sewn or riveted to the main body at spaced intervals, and corresponding female snaps are injection-molded and attached to the guide section. Fine adjustment is also possible by designing a narrow spacing between the snaps.

[0094] As a practical example, if a user wishes to prevent the wire from slipping while hiking, securing the upper guide to the top of the toothed snap ensures stable upper clamping force. Furthermore, since the snap mechanism provides a clear fastening state, there is no risk of the wire becoming dislodged due to body shape or movement, and it offers excellent position retention even under strong external impacts.

[0095] As explained above, the present invention effectively solves the problem of left-right and up-down vibration inherent in conventional backpacks by providing a structure to prevent shaking of a bag that adheres closely to the wearer's back during exercise. Conventional backpacks were secured to the wearer's body solely by shoulder straps, which caused the bag to detach from the back and shake during vigorous movements; however, the present invention fundamentally improves this problem by ensuring the main body of the bag adheres closely to the user's body through a shaking prevention part mounted on the outer side of the storage body.

[0096] The anti-sway section features an upper and lower tightening wire that extend horizontally to stably wrap around the wearer's torso, and these wires are connected at both ends to form an integrated tightening structure. Unlike conventional waist belts or separate straps, this structure provides balanced fixing force from both the top and bottom, ensuring that the entire bag is stably secured around the user's central axis and suppressing shaking.

[0097] The fixation of the wire is further reinforced by the upper and lower guides mounted on the storage body. The upper and lower guides are implemented with a ring-shaped sliding structure, which prevents the wire from slipping out in the vertical direction while allowing it to move flexibly in the horizontal direction according to the wire's elasticity and tightening. Through this, the user can obtain a secure fixation that responds naturally to movement and prevent unnecessary shifting or pulling of the wire.

[0098] The upper and lower tightening wires can be easily secured and released by a tightening fixing member positioned on the front of the user. The tightening fixing member according to the present invention is configured to apply tightening force by pulling both wires simultaneously and to be secured without separate operation, thereby enabling much faster and simpler wearing and unwearing compared to conventional complex strap adjustment methods. This provides the advantage of easily adjusting the tightening state as needed during exercise.

[0099] Furthermore, the upper and lower guides are not limited to providing a simple fixed position; they are structured to allow sliding and fixation according to the wearer's body type and wearing position, thereby providing a customized fit for a wide range of users. In conventional technology, position adjustment was difficult, leading to discomfort depending on body type; however, in the present invention, since the user can directly set the position of the guide parts, limitations caused by differences in body shape are eliminated.

[0100] Consequently, the present invention provides a function that securely fastens the bag to the body without hindering the wearer's free movement during exercise, thereby enhancing comfort, safety, and storage stability. This improves upon the structural limitations and inconveniences of conventional technology and realizes the value of a functional bag usable in various situations, such as outdoor activities, fitness, and commuting.

[0101] Finally, the present invention has great technical significance in that it provides a high-performance bag that comprehensively compensates for the shortcomings of conventional technology by not merely improving the appearance of the bag through the above configurations, but by structurally integrating key functions related to bag usage, such as the tightening method, position adjustment, ease of wearing, and anti-shake.

[0102] The above detailed description of the present invention describes only specific embodiments thereof. However, it should be understood that the present invention is not limited to the specific forms mentioned in the detailed description, but rather should be understood to include all variations, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.

[0103] In other words, the present invention is not limited to the specific embodiments and descriptions described above, and any person skilled in the art to which the present invention pertains can make various modifications without departing from the essence of the invention as claimed in the claims, and such modifications fall within the scope of protection of the present invention.
