Description

TECHNICAL FIELD

[0001] The present invention relates to the field of travel equipment technology, specifically to the subfield of multifunctional integrated travel equipment. In particular, it relates to a travel bag integrating a telescopic support structure and a clothing hanging rack structure. This travel bag is designed for scenarios such as travel, performances, sports competitions, and outdoor camping, which require frequent clothing changes or temporary storage of items. It addresses the limitations of traditional travel equipment that have single functions and insufficient adaptability to various scenarios. The invention achieves integrated all-scenario functionality including storage, volume expansion, clothes hanging, and privacy changing, meeting the storage and clothing management needs for individual travel, team performances, and other varied contexts. It significantly enhances the practicality and applicability of travel equipment.BACKGROUND OF THE INVENTION

[0002] With the diversification of travel scenarios, user demands for travel bags have evolved from simple storage to multifunctional integration, especially in outdoor, performance, and competition settings. Users not only require sufficient storage space but also convenient temporary clothes hanging and changing facilities, as well as privacy for changing. However, existing travel bags and related integrated equipment suffer from several technical shortcomings and fail to meet these needs:

[0003] Conventional travel bags (such as backpacks and handheld luggage) have highly single-functionality limited to basic storage. They lack the supporting structures needed for hanging clothes and cannot form temporary changing spaces. When users need to change clothes outdoors, they must carry additional accessories like hangers or portable changing tents, increasing the load and reducing portability.

[0004] Some existing patents attempt to combine supporting structures or hanging functions with travel equipment but still have significant deficiencies:

[0005] U.S. Pat. No. 10,512,318 B2 (McKelvey) discloses a luggage system with a detachable storage top and support frame. The support frame depends on the luggage's own pull rod system for fixation and support, limiting its use to specific luggage equipped with such rods and incapable of adapting to ordinary travel bags or backpacks, thus restricting its applicability. Moreover, its installation requires disassembling the luggage storage top, involving cumbersome steps taking more than 10 minutes for a single user, resulting in low efficiency.

[0006] U.S. Pat. No. 10,905,214 B1 (Wicelaw) proposes a foldable box and hanger combination comprising more than three buckles, hinges, and linkage rods. This structure is complex and requires sequential unlocking of multiple buckles to fold or unfold. Folded parts still require separate storage, prone to loss. Further, it serves only as a suitcase frame and lacks basic storage functions for travel bags, showing low integration of functionality.

[0007] US 2009 / 0321204 A1 (Barkow et al.) designs a convertible wardrobe luggage with two thin upright rods forming a hanging structure. However, the rods are fixed simply by slots and tilt noticeably under loads over 2 kg, lacking sufficient support stability. The structure does not integrate privacy screening components, requiring additional privacy curtains. It does not meet the “integrated” requirement.

[0008] In summary, the prior art fails to overcome contradictions among single functionality, complex structure, narrow applicability, and poor portability. It does not achieve efficient integration of travel bags with support structures, clothing hanging racks, and privacy changing spaces. Users still need to carry extra accessories for multiple scenarios, and convenience and adaptability remain to be improved.SUMMARY OF THE INVENTION(1) Technical Problem to be Solved

[0009] The present invention aims to overcome the deficiencies of the prior art by addressing core issues in existing travel equipment. It provides a travel bag with a rational structure, diverse functionality, and ease of use, featuring a telescopic support structure and a clothing hanging rack structure. Specifically, it solves the following technical problems:

[0010] Existing travel bags have single functions and cannot simultaneously meet the multi-scenario demands of basic storage, volume expansion, clothes hanging, and privacy changing, resulting in poor scenario adaptability;

[0011] Existing integrated supporting structures in travel equipment either depend on specific components (such as luggage pull rods) leading to limited applicability, or have complex structures (such as multi-buckle folding mechanisms) leading to low efficiency in switching configurations, failing to adapt to frequent switching scenarios like backstage quick dressing;

[0012] Existing clothes hanging / changing related travel equipment lack stable supporting structures (e.g., thin upright rods prone to tilt) and lack integrated designs for privacy screening, requiring extra accessories and resulting in poor portability;

[0013] Existing product supporting parts (e.g., upright rods, crossbars) have scattered storage without dedicated storage solutions, prone to loss or collision wear, affecting service life and portability.(2) Technical Solution

[0014] To achieve the above objectives, the invention provides the following technical solution:

[0015] A travel bag with a telescopic support structure and clothing hanging rack structure, comprising an upper bag body and a lower bag body; a latching mechanism disposed inside the upper bag body; a limiting mechanism disposed inside the lower bag body; and supporting components housed inside the lower bag body;

[0016] The supporting components comprise a case support rod, a telescopic upright rod, a crossbar assembly, a limit pin, and an extension rod;

[0017] The crossbar assembly is used for hanging clothes; the telescopic upright rod connects the crossbar assembly with the upper and lower bag bodies; the case support rod supports the upper and lower bag bodies.

[0018] The latching mechanism comprises symmetrically fixed latching blocks inside the upper bag body, each having a latching slot and an insertion slot.

[0019] The limiting mechanism comprises symmetrically fixed limiting blocks inside the lower bag body, each provided with a limiting slot corresponding to the latching slot.

[0020] The upper bag body includes a protective housing and a sealing layer; the lower bag body includes a flexible bag wall and a collection box for storing the supporting components.

[0021] The case support rod and telescopic upright rod can be inserted into the latching slot and limiting slot, respectively, and fixed by the limit pin.

[0022] The crossbar assembly can be sleeved on the telescopic upright rod; the extension rod can be inserted into the connecting block on the crossbar assembly for hanging a privacy curtain.(3) Beneficial Effects

[0023] The invention achieves three usage configurations of the travel bag through the above structure:

[0024] Storage configuration: all supporting components are stored within the bag, enabling use as a conventional travel bag;

[0025] Expanded volume configuration: the case support rod props open the bag to increase storage space;

[0026] Clothes hanging and changing configuration: the telescopic upright rod and crossbar assembly build a clothes hanging rack, and curtains can be added to form a private changing space.

[0027] The invention integrates the travel bag with telescopic support structure and clothing hanging rack into one, providing stable structure and convenient switching, significantly enhancing the practicality and applicability of the travel bag.BRIEF DESCRIPTION OF DRAWINGS

[0043] The technical solutions of the exemplary embodiments of the present application are described clearly and completely below in conjunction with the figures of the present application. It is apparent that the described embodiments are only a part of the embodiments of the present application and not all possible embodiments. All other embodiments obtained by those skilled in the art based on the disclosed embodiments without creative efforts shall fall within the scope of the protection of the present application.

[0044] A preferred embodiment of this application provides a travel bag comprising an upper bag body (1) and a lower bag body (2). The upper bag body (1) is internally equipped with a latching mechanism (3). The lower bag body (2) is internally equipped with a limiting mechanism (4) and supporting components (5). The supporting components (5) include a case support rod (501), a telescopic upright rod (502), a crossbar assembly (503), an extension rod (504), and a limit pin (505).

[0045] In the storage configuration, all supporting components (5) are housed within a collection box (202), while the sealing layer (102) is closed via a zipper.

[0046] In the expanded volume configuration, the case support rod (501) is inserted into the latching slot (302) and limiting slot (402), and fixed in place using the limit pin (505), causing the upper bag body (1) to be propped upward to increase storage capacity.

[0047] In the clothing hanging and changing configuration, the telescopic upright rod (502) is inserted into another set of latching slots (302) and limiting slots (402), and after height adjustment, the crossbar assembly (503) is installed for hanging clothes. For privacy changing purposes, the extension rod (504) is inserted into the connecting block (6), to attach a privacy curtain and thereby form a changing space.

[0048] In the embodiment of the present application, the travel bag employs a modular design for supporting components, allowing quick disassembly and assembly among the case support rod, telescopic upright rod, crossbar assembly, extension rod, and limit pin. Users can flexibly combine these parts according to their needs, achieving different usage configurations to enhance adaptability and flexibility. This modular design facilitates maintenance and component replacement, thereby extending the service life of the equipment.

[0049] Referring to FIGS. 1-2, in the embodiment of the present application, when the travel bag is in the storage configuration, the supporting components (5)—including the case support rod (501), telescopic upright rod (502), crossbar assembly (503), extension rod (504), and limit pin (505)—are all placed within the collection box (202) of the lower bag body (2). The interior of the collection box (202) is provided with contour-fitting recesses adapted to the shapes of each supporting component (5), which prevent collision and abrasion of the components during transport. In addition, a protective housing (101) of the upper bag body (1) covers the top of the collection box (202) to provide secondary protection, while the sealing layer (102) is tightly closed by a zipper, ensuring that the internal components are isolated from external dust and moisture.

[0050] Referring to FIG. 3, in the embodiment of the present application, when the travel bag is switched to the expanded volume configuration, the case support rod (501) is first inserted into the latching slot (302) of the latching mechanism (3) and the limiting slot (402) of the limiting mechanism (4), then the limit pin (505) is inserted into a preformed through-hole on the case support rod (501) to lock the position of the case support rod (501). At this time, the flexible bag wall (201) of the lower bag body (2) is stretched upward by the support of the case support rod (501), resulting in an increase of the internal storage space by 1.5-2 times compared to the storage configuration, allowing storage of folded bedding, large garments, and more travel items. In the expanded volume configuration, the flexible bag wall uses multi-layer composite structures to maintain support while preventing deformation, ensuring shape stability.

[0051] Referring to FIGS. 4-5, in the embodiment of the present application, in the clothing hanging and changing configuration, the telescopic upright rod (502) is inserted into a different set of latching slots (302) and limiting slots (402), and the height of the telescopic upright rod (502) can be adjusted according to user needs—for example, adjusted to 1.6 m for hanging short jackets, or to 1.8 m for hanging long down coats. The crossbar assembly (503) is then sleeved onto the tops of two telescopic upright rods (502), with anti-slip pads at the connection to prevent lateral movement of the crossbar assembly (503) during use, thereby ensuring stable hanging of clothes.

[0052] Referring to FIG. 8, in the embodiment of the present application, if it is necessary to form a private changing space in the clothing hanging and changing configuration, the extension rod (504) is inserted into a connecting block (6) provided on the crossbar assembly (503). Each crossbar assembly (503) is provided with two connecting blocks (6) symmetrically arranged at both ends, each capable of receiving one extension rod (504). A privacy changing space can thus be constructed by means of the extension rod (504) and the crossbar assembly (503), meeting the privacy needs for individual changing.

[0053] In some embodiments, the surfaces of the supporting components (5) are all treated with special protective coatings, providing corrosion resistance, wear resistance, and scratch resistance suitable for outdoor environments. The protective coating materials have passed environmental certification, ensuring user safety and no adverse environmental impact. Among them, the case support rod (501) and telescopic upright rod (502) adopt hot-dip galvanizing, maintaining rust resistance for more than five years; the limit pin (505) and extension rod (504) use plastic powder coating with a surface layer thickness of 0.1-0.2 mm, effectively isolating air and moisture and preventing rust deterioration in use. The supporting components are made from lightweight, high-strength alloys, balancing strength and portability, and meeting the demands of prolonged outdoor use.

[0054] In certain embodiments, the connecting block (6) on the crossbar assembly (503) is integrally formed with the crossbar assembly (503). The inner diameter of the hollow connecting block (6) exceeds the outer diameter of the extension rod (504) by 0.5 mm, facilitating rapid insertion and preventing excessive play that could lead to shaking. In addition, the outer side of the connecting block (6) is equipped with an elastic press buckle; after the extension rod (504) is inserted, pressing the buckle embeds it into a positioning hole on the extension rod (504) surface, achieving dual fixation of the extension rod (504).

[0055] Referring to FIGS. 1-6, in the embodiment of the present application, the protective housing (101) is not a standalone box, but a textile composite shape-retaining structure integrated onto the upper portion of the upper bag body (1). It is constructed by multi-layer lamination of Oxford fabric, identical in origin to the sealing layer (102) and flexible bag wall (201), with thin shape-retaining interlining placed between layers or with stitched or hot-pressed frame strips formed circumferentially at the opening to maintain the rectangular profile of the upper bag body's top opening during use and assembly. This prevents collapse without support and facilitates the smooth closure of the sealing layer (102) as well as convenient access and storage of items. In expansion configuration, the structure provides clear alignment space for insertion of the case support rod (501) into the latching slot (302) of the latching mechanism (3); it is not intended as a load-bearing or shock-resistant member, and will slightly deform under vertical compression together with the bag body.

[0056] Other optional embodiments may achieve the same purpose by localized reinforcement with similar textile materials. For example, high-weight fusible interlining or fiber-reinforced tape may be set around the opening, additional reinforcing stitches or shape-retaining strips may be added to the corners, or multilayer Oxford cloth may be partially compounded with fusible adhesive to form a ring-shaped shape-retaining zone, thereby enhancing opening rigidity and boundary stability. This ensures guidance and alignment during closure, item access, and component assembly.

[0057] In some embodiments, the sealing layer (102) of the upper bag body (1) adopts a high-elasticity composite material that not only provides excellent sealing performance but also possesses tear resistance and high-temperature resistance. This sealing layer is made from the same durable fabric as the flexible bag wall of the lower bag body, ensuring overall structural strength and extensibility. For example, waterproof Oxford fabric treated with a PTFE coating on the fabric surface achieves an IPX4 water resistance rating. Even when the travel bag is briefly exposed to rain, external water cannot penetrate the interior of the sealing layer (102). Additionally, the sealing layer is equipped with a metal bi-directional zipper, and the zipper teeth are nickel-plated to effectively prevent rust and jamming under humid conditions.

[0058] In some embodiments, the collection box (202) of the lower bag body (2) is a flexible storage space formed based on the structure of the lower bag body itself, rather than a separately assembled rigid box. Specifically, it is formed by the natural extension of the flexible bag wall (201) of the lower bag body to the bottom of the bag, creating a flexible soft bottom integrated with the flexible bag wall (201) by one-piece sewing using homologous 600D polyester Oxford fabric. The entire structure is soft and bendable without additional rigid support, allowing flexible adaptation of storage space as the lower bag body (2) deforms. It can be designed with multifunctional compartments that automatically adjust the storage space based on the shapes of different supporting components, maximizing space utilization while ensuring components do not interfere. Within this flexible bottom, a waterproof nylon zipper integrated with the bottom material is sewn. When storing supporting components (5), the user simply unzips the waterproof nylon zipper, unfolding the flexible bottom into a flat soft bearing surface, onto which the case support rod (501), telescopic upright rod (502), limit pins (505), and other parts can be directly placed without dismantling or installing any independent box components. After placement, closing the zipper encloses the bottom inside the lower bag body (2), forming a flexible box-shaped storage space with a top opening, achieving centralized storage of the supporting components (5).

[0059] In some embodiments, the interior of the collection box (202) of the lower bag body (2) is provided with removable partitions. Users can adjust the internal space of the collection box (202) by installing or removing the partitions according to the quantity and size of the supporting components (5). For example, when more extension rods (504) are to be stored, the partitions can be removed to form a larger space for extension rods (504); when storing small components such as limit pins (505), the partitions can be installed to create separate smaller spaces to prevent loss of small components.

[0060] In certain embodiments, the collection box (202) of the lower bag body (2) is detachably connected to the inner side of the flexible bag wall (201) by hook-and-loop fasteners (Velcro) around its perimeter. If components inside the collection box (202) become contaminated with dust or stains, users can remove the collection box (202) from the flexible bag wall (201) for cleaning in its entirety. Meanwhile, the bottom of the collection box (202) is equipped with non-slip rubber pads, so that even when the travel bag is placed on a smooth suitcase surface, the collection box (202) will not shift with the travel bag.

[0061] In some embodiments, the latching mechanism (3) of the upper bag body (1) includes two symmetrically arranged latching blocks (301). The latching blocks (301) are fixedly stitched to the inner side of the protective housing (101) by high-strength sewing thread. The latching slot (302) on each latching block (301) is set to a depth of 8-10 cm, fully enveloping the top of the case support rod (501) or telescopic upright rod (502), thereby enhancing the stability of the supporting structure. In addition, the insertion slot (303) on the latching block (301) can be used to insert spare limit pins (505) or other small auxiliary components during travel bag use, preventing loss of small parts.

[0062] In some embodiments, the latching blocks (301) symmetrically arranged in the latching mechanism (3) of the upper bag body (1) are integrally molded and connected to the inner wall of the protective housing (101) via injection molding. Compared to sewing fixation, this connection method improves connection strength by over 40%, effectively preventing the latching blocks (301) from detaching after prolonged use. The insertion slot (303) on the latching blocks (301) has an internal diameter precisely matched to the outer diameter of spare limit pins (505). An elastic silicone ring is set at the opening of the insertion slot (303) so that when the limit pin (505) is inserted, a tight fit is formed, preventing the limit pin (505) from sliding out during travel bag movement. The limit pin (505) adopts a unique tooth-shaped locking structure to enhance fixation reliability, avoiding structural instability caused by loosening due to vibration.

[0063] Referring to FIG. 6, in some embodiments, the limiting mechanism (4) of the lower bag body (2) consists of two limiting blocks (401) symmetrically fixed to the inner wall of the flexible bag wall (201). The limiting slot (402) on the limiting block (401) is vertically aligned with the latching slot (302) of the upper bag body (1), ensuring the case support rod (501) or telescopic upright rod (502) can be vertically inserted without deviation. The inner wall of the limiting slot (402) is coated with a wear-resistant resin layer, reducing friction with the supporting components (5) during repeated insertion and extraction and extending the service life of the limiting mechanism (4).

[0064] Referring to FIG. 9, in some embodiments, the symmetrically arranged latching blocks (301) in the latching mechanism (3) of the upper bag body (1) are integrally injection-molded with the inner wall of the protective housing (101), improving connection strength by over 40% compared to stitching and providing improved durability. The insertion slot (303) on the latching block (301) is precisely adapted to the outer diameter of the spare limit pin (505), with an elastic silicone ring at the opening for a tight fit, avoiding slippage during movement. In the limiting mechanism (4) of the lower bag body (2), the limiting block (401) is made of ABS engineering plastic, which combines impact resistance and lightweight characteristics, being only one-third the weight of traditional metal limiting blocks, thus reducing the total weight of the travel bag. The depth of the limiting slot (402) is set to 6-8 cm, corresponding to the length of the inserted ends of the case support rod (501) and telescopic upright rod (502), ensuring the supporting components (5) do not shake after insertion, further enhancing support stability.

[0065] In some embodiments, the surface of the case support rod (501) is provided with axial reinforcing ribs, uniformly distributed along the length of the rod body in a quantity of 4-6 ribs. This increases the bending resistance of the case support rod (501) by more than 50%. When the travel bag is in the expanded volume configuration and filled with heavy items, the case support rod (501) will not bend or deform from excessive force, ensuring storage space stability.

[0066] Referring to FIG. 7, in some embodiments, the telescopic upright rod (502) adopts a multi-section telescopic structure, with each section of the rod body connected by a spring-based positioning ball. To adjust height, the user simply presses the positioning ball to extend or retract the rod body, with the positioning ball snapping into the corresponding positioning hole for height fixation. The maximum extension length of the telescopic upright rod (502) can reach 2 meters, which is suitable for hanging overcoats, long skirts, and other long garments, as well as meeting various user height requirements for assembling a changing space.

[0067] Further, the telescopic upright rod (502) may adopt a multi-section threaded screw-type telescopic structure to achieve height adjustment, as an alternative to the spring-loaded positioning ball connection. Specifically, adjacent rod sections of the telescopic upright rod (502) have the inner rod section's outer wall formed with external threads and the outer rod section's inner wall formed with matching internal threads, with a thread pitch set at 2-3 mm to ensure adjustment precision and structural stability. When adjusting height, the user rotates the inner rod section, causing it to extend or retract along the thread path inside the outer rod section. Once adjusted to the desired height, the self-locking feature of the threaded structure fixes the height without additional positioning elements. The load-bearing capacity of this structure is comparable to the spring-loaded positioning ball structure (able to withstand 3-5 kg tensile force), and the threaded connection offers better sealing to reduce dust and moisture ingress into the rod body, preventing wear. This structure also avoids potential elastic failure of spring-loaded positioning balls over long-term use, making it suitable for outdoor scenarios with high durability requirements. It differs substantially from existing spring ball telescopic structures in connection principle and operation, effectively mitigating infringement risks.

[0068] Additionally, in other embodiments, the telescopic upright rod (502) may utilize a multi-section snap-fit telescopic structure. In this structure, the outer rod section sidewall is provided with 2-3 annular snap slots spaced 10-15 cm apart to meet common height adjustment needs. The inner rod section end includes a plastic snap buckle with elastic reset function, made of fatigue-resistant PA66 nylon capable of thousands of open-close cycles. During adjustment, the user presses the snap buckle on the inner rod section to retract it out of the current snap slot, then pulls the inner rod section to the target height and releases the buckle, which elastically snaps into the corresponding snap slot to fix the height. This structure is highly intuitive, requiring no rotation or precise alignment with positioning holes, allowing a single user to complete one height adjustment within 10 seconds. The clearance between the snap buckle and snap slot is 0.3 mm, ensuring no wobble after adjustment. This meets hanging clothes and changing space setup functional needs, and its “snap buckle-snap slot” engagement distinctly differs from the spring ball structure, providing more structural options to avoid infringement.

[0069] Further, the telescopic upright rod (502) rod body is made of aluminum alloy with a wall thickness controlled between 1.2-1.5 mm. This ensures load-bearing capacity (withstanding 3-5 kg tensile force) while minimizing weight. Each rod section surface is printed with a height scale line at 1 cm precision, enabling users to accurately set rod height based on the scale without repeated measurement.

[0070] In some embodiments, the length and cross-sectional dimensions of the crossbar assembly (503) are optimized to balance load-bearing capacity and portability, accommodating various clothing weights and volumes. Further, a two-section splicing structure may be used, where the two rod sections are connected via built-in threaded interfaces. When disassembled, each section is only half the total assembled length, facilitating storage in the collection box (202). During assembly, wear-resistant lubricating grease is applied to the threading connection, enabling users to quickly screw the parts together while reducing wear from long-term assembly and disassembly, thereby extending the service life of the crossbar assembly (503).

[0071] In some embodiments, when the travel bag is in clothes hanging and changing configuration and a privacy changing space is set up, the extension rod (504) length is 1.2-1.5 meters. Two extension rods (504) inserted into the connecting blocks (6) at both ends of the crossbar assembly (503) allow a privacy curtain-enclosed dressing space with an internal width of 1.2-1.4 meters and depth of 0.8-1 meter. This space can accommodate a single person standing for changing as well as folded change of clothing, enhancing ease of use.

[0072] In some embodiments, switching among the three configurations of the travel bag does not require any additional tools. When switching from the storage configuration to the expanded volume configuration, the user only needs to open the sealing layer (102), take out the case support rod (501) and limit pin (505) from the collection box (202), and insert and fix them in place. When switching from the expanded volume configuration to the clothes hanging and changing configuration, the user only needs to remove the case support rod (501) and replace it with the telescopic upright rod (502) and crossbar assembly (503). The entire switching process takes about 3 to 8 minutes, making it very convenient for outdoor scenarios such as travel, performances, and the like. Further, the bag body joining process is optimized by using heat sealing and seamless bonding techniques, which enhance the overall waterproof performance and aesthetic appearance.

[0073] Compared to the prior art, the beneficial effects of the present utility model are:

[0074] The utility model provides a travel bag with an integrated telescopic support structure and clothing hanging rack structure. The upper bag body (1) is internally equipped with a latching mechanism (3); the lower bag body (2) is internally equipped with a limiting mechanism (4); the lower bag body (2) houses supporting components (5). The supporting components (5) include a case support rod (501), a telescopic upright rod (502), a crossbar assembly (503), a limit pin (505), and an extension rod (504). The crossbar assembly (503) is used for hanging clothes; the telescopic upright rod (502) connects the crossbar assembly to the upper and lower bag bodies; the case support rod (501) supports the upper and lower bag bodies.

[0075] Through the above structure, the travel bag realizes three usage configurations: in the storage configuration, all supporting components are stored inside the bag, allowing use as a conventional travel bag; in the expanded volume configuration, the bag is propped open by the case support rod, effectively increasing storage capacity; in the clothes hanging and changing configuration, the telescopic upright rod and crossbar assembly form a clothing hanging rack, and curtains may be added to form a private changing space.
