Description

Technical Field

[0001] This utility model belongs to the field of luggage technology, and in particular relates to a modular luggage. Background Technology

[0002] Most bags and luggage products on the market are manufactured with the front and back shells separate, and then connected by connectors such as zippers or metal frames to form a whole bag. The bag can be opened from the connection point to put items into or take items out of the bag.

[0003] However, the aforementioned structure of the luggage product has several drawbacks. First, it is inconvenient to place luggage pieces thicker than half the size of the suitcase (such as the back shell). Second, because the opening area of ​​the shell encircles the entire suitcase along its vertical center line, the overall strength of the suitcase is relatively low. Third, since the opening is located between the front and rear shells, handles and other components cannot be installed in the exact center of the top or side of the suitcase, making it difficult to apply downward force when lifting the suitcase, causing the center of gravity to shift and making lifting inconvenient. Finally, the casters and pull rods of the front-to-back assembled suitcase are difficult to conceal inside the suitcase, resulting in weaker structural strength for the casters and pull rods and a less aesthetically pleasing appearance.

Detailed Implementation

[0018] The present invention provides a more detailed description of a modular bag / suit based on the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims.

[0019] The term "comprising" and its variations as used herein are open-ended inclusions, meaning "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Definitions of other terms will be given in the description below.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0021] See Figures 1-2 This embodiment provides a modular bag, which enables the bag to be assembled by combining the upper and lower structures. Its main structure includes an upper box 1, a lower box 2, a side box 3, and an external connector 4.

[0022] Taking a conventional bag structure as an example, the bag is a cuboid structure with length, width, and height. The height direction of the bag is defined as the direction in which its long side is placed vertically.

[0023] Along the height direction of the bag, the upper box 1 is located in the space above the bag, and the lower box 2 is located in the space below the bag. After the upper box 1 and the lower box 2 are joined together, they form the complete height structure of the bag. Specifically, the bottom of the upper box 1 is provided with a first connecting part 101, and the top of the lower box 2 is provided with a second connecting part 201. The first connecting part 101 and the second connecting part 201 are respectively provided with corresponding splicing edges on opposite sides. The outlines of the splicing edges of the first connecting part 101 and the second connecting part 201 are arranged in a complementary irregular splicing configuration, so that when the upper box 1 and the lower box 2 are joined together along the height direction of the bag, the connection between the upper box 1 and the lower box 2 forms a complete and seamless continuous plane.

[0024] The first connecting part 101 and the second connecting part 201 are respectively provided with a plurality of fixing holes 102.

[0025] The extended shape of the outer connector 4 is adapted to the horizontal cross-sectional outer contour of the upper box 1 and the lower box 2. Taking a conventional cuboid structure bag as an example, the outer connector 4 has a "U" shape and can be attached to the outer surface of the upper box 1 and the lower box 2 in the horizontal direction. Specifically, the outer connector 4 has several fixing shafts 401 on the side facing the upper box 1 and the lower box 2, which are adapted to the distribution and size of the fixing holes 102. Several fixing shafts 401 in the same outer connector 4 can pass through several fixing holes 102 in the first connecting part 101 and the second connecting part 201 at the same time, so that the upper box 1 and the lower box 2 are fixedly connected and cannot be separated or disassembled.

[0026] Meanwhile, after the upper box 1 and the lower box 2 are assembled, an opening is formed in the horizontal direction of the bag. The side box 3 can be opened and closed or movably covered at the opening. Thus, in this embodiment, the opening is located on one side of the bag, and the thickness of the bag is the horizontal thickness of the upper box 1 and the lower box 2. When the bag is laid flat on a horizontal surface, it is convenient to directly place thicker, larger luggage into the internal space of the bag by opening the side box 3. At the same time, the upper box 1 and the lower box 2, as the main load-bearing structures of the bag, no longer have a connecting opening at the center line of the vertical height of the bag, which can significantly improve the overall structural strength and stability of the bag.

[0027] The specific structure and function of the modular bag provided in this embodiment will be described in further detail below: Preferably, in one embodiment, the shape of the splicing edge of the first connecting part 101 and the second connecting part 201 includes bending along a wave shape, bending along a polygon, or extending along a straight line, wherein the specific shape of the polygon bending includes, but is not limited to, triangle, rectangle, trapezoid, etc.

[0028] Furthermore, in one embodiment, the wavy or polygonal bends of the first connecting part 101 and the second connecting part 201 include crest regions and trough regions. When the upper box 1 and the lower box 2 are assembled vertically, the crest region of the first connecting part 101 is inserted into the trough region of the second connecting part 201, and the crest region of the second connecting part 201 is inserted into the trough region of the first connecting part 101. Based on the wavy or polygonal bend edge design, the first connecting part 101 and the second connecting part 201 interlock with each other, improving the connection stability of the first connecting part 101 and the second connecting part 201 in the horizontal direction of the bag.

[0029] Fixing holes 102 are respectively provided in the crest regions of the first connecting part 101 and the second connecting part 201.

[0030] Meanwhile, the fixing shaft 401 of the external connector 4 is staggered with a first shaft group and a second shaft group along the height direction of the bag. The first shaft group is distributed relatively above, and the second shaft group is distributed relatively below. During the process of the fixing shaft 401 passing through a number of fixing holes 102 in the first connecting part 101 and the second connecting part 201, the fixing shaft 401 in the first shaft group is used to pass through the fixing holes 102 in the crest area of ​​the second connecting part 201, and the fixing shaft 401 in the second shaft group is used to pass through the fixing holes 102 in the crest area of ​​the first connecting part 101, thereby realizing the integrated connection of the external connector 4 between the upper box 1 and the lower box 2.

[0031] Preferably, in one embodiment, the main structure of the assembled bag also includes an inner connector 5. The extended shape of the inner connector 5 is adapted to the internal contour of the horizontal cross section of the upper box 1 and the lower box 2. That is, the inner connector 5 also has a "U" shaped structure and can be attached to the inner surface of the upper box 1 and the lower box 2 in the horizontal direction. Specifically, the inner connector 5 is provided with a number of limiting holes 501 that are adapted to the distribution and size of the fixed shaft 401 and the fixed hole 102. The inner connector 5 is configured such that after the fixed shaft 401 of the outer connector 4 passes through the fixed hole 102 of the upper box 1 or the lower box 2, it can also pass through the limiting holes 501 until the outer connector 4 is in contact with the surface of the upper box 1 and the lower box 2. Then, the fixed shaft 401 is fixedly connected to the inner connector 5 by the fixing member. This achieves a stable connection between the outer connector 4 and the upper box 1 and the lower box 2 in the horizontal direction of the bag, and further prevents the upper box 1 and the lower box 2 from shifting and separating in the horizontal direction of the bag.

[0032] The fasteners include those that use nut connections or riveting to fix the fixed shaft 401 to the inner connecting member 5.

[0033] Preferably, in one embodiment, the splicing edges of the first connecting part 101 and the second connecting part 201 are further fixedly connected by sewing, thereby further improving the connection strength between the first connecting part 101 and the second connecting part 201.

[0034] Preferably, in one embodiment, the inner connector 5 is fixed in the internal splicing space of the upper box 1 and the lower box 2 by snap-fit, so as to realize the fixed connection between the inner connector 5 and the bag, that is, to further ensure the stability of the connection between the outer connector 4 and the upper box 1 and the lower box 2.

[0035] Preferably, in one embodiment, the outer connector 4 and the inner connector 5 are integrally molded using injection molding materials, so that the outer connector 4 and the inner connector 5 have high geometric accuracy and structural strength, ensuring that the bag has superior overall structural strength.

[0036] The upper box 1, lower box 2, and side box 3 are all integrally molded using injection molding materials, which gives the upper box 1, lower box 2, and side box 3 high geometric accuracy and structural strength, ensuring that the bag has superior overall structural strength.

[0037] Preferably, in one embodiment, the side box 3 and the bag opening are connected by a zipper assembly to achieve an openable or movable connection.

[0038] Preferably, in one embodiment, a first handle 6 is fixedly provided in the center area of ​​the top surface of the upper box 1 along the height direction of the bag. That is, in this embodiment, since there is no connecting opening at the center of the vertical height of the bag, the first handle 6 can be set in the center area of ​​the top of the bag. When the bag is placed vertically and the bag is lifted vertically through the first handle 6, the bag will not tilt left, right, front, or back, making it easier and safer to carry for a long time.

[0039] Along the horizontal direction of the bag, a second handle is fixedly provided in the central area of ​​the bag formed by the same side of the upper box 1 and the lower box 2. One end of the second handle is fixedly connected to the upper box 1, and the other end is fixedly connected to the lower box 2. That is, the second handle is set in the center of both sides of the joint area of ​​the upper box 1 and the lower box 2. Similarly, since there is no longer a connecting opening at the center ring of the vertical height of the bag, the second handle can be set in the central area of ​​the side of the bag. When the bag is placed horizontally and the bag is lifted vertically through the second handle, the bag will not tilt left, right, front, or back, making it easier and safer to carry for a long time.

[0040] Preferably, in one embodiment, the bottom of the lower case 2 is provided with casters 7 along the height direction of the case, and a pull rod assembly 8 is provided on the side of the case away from the side case 3. The pull rod assembly 8 can extend upward along the height direction of the case, or retract and be accommodated inside the case along the height direction of the case. The combination of casters 7 and pull rod assembly 8 further improves the flexibility of the case's movement and ease of use.

[0041] The caster wheel 7 includes a caster wheel body and a caster wheel fixing groove, which are rotatably connected and extend into the interior space of the lower housing 2. The pull rod assembly 8 includes a pull rod body and a pull rod receiving groove, which are slidably connected and extend into the interior space of the upper housing 1.

[0042] In this embodiment, the concealed design of the universal wheel fixing groove and the pull rod receiving groove can reduce the height of the bag off the ground, prevent the universal wheel fixing groove and the pull rod receiving groove from being easily impacted by external forces, improve the structural strength of the universal wheel 7 and the pull rod assembly 8, and improve the aesthetics of the bag.

[0043] In summary, this utility model provides a modular bag, including an upper box 1, a lower box 2, and a side box 3. The upper box 1 and the lower box 2 are aligned by a wave-shaped edge, and are fixedly connected by an outer connector 4 and an inner connector 5. The side box 3 can be opened and closed or movably covered by the opening formed by the upper box 1 and the lower box 2 after assembly. Therefore, in this utility model, the main load-bearing structure of the bag no longer uses a front and rear box assembly method, but instead... The upper and lower compartments are designed to be joined together, with the thickness of the upper compartment 1 and the lower compartment 2 being the same as the thickness of the bag. This facilitates the direct placement of large luggage. At the same time, there is no longer a connecting opening at the center of the vertical height of the bag, which can significantly improve the overall structural strength of the bag. The handle can be placed in the center area of ​​the top or side of the bag, which makes it easier to distribute the force evenly and stabilize the center of gravity when the bag is lifted. In addition, the universal wheel fixing groove and the pull rod storage groove can be hidden inside the bag, which effectively improves the structural strength and aesthetics of the universal wheel and pull rod assembly.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
