Description

Technical Field

[0001] The utility model belongs to the technical field of daily necessities, and in particular relates to a soft and hard combined wide pull-bar suitcase. Background Art

[0002] Currently, there are some soft and hard combination luggage bags on the market. For example, it includes a hard bottom shell with a groove shape, and the outer surface of the bottom is used to install rollers, and the rest of the bag is a flexible structure. The bottom shell and the flexible structure together form a bag body or box structure with storage space. This type of bag is easy to set up as a backpack, so that the main body can be placed on the ground and pulled, or it can be carried on the user's shoulders for use. Another type of bag generally includes a hard back and bottom surface. In some cases, the hard bottom surface and back surface are an integrated structure, and the other surfaces of the bag are replaced by a flexible structure. This type of bag is easy to set up with various pull rods. Although the above-mentioned soft and hard combination bags each have their own advantages, they all have the problem that the flexible structure is relatively weak in rigidity, lacks support, and is easily deformed during use, which affects storage space.

In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0022] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0023] As the instruction manual Figure 1-3As shown, the present invention discloses a flexible and rigid wide-handle suitcase, comprising an upper shell 1, a lower shell 3, and flexible sidewalls 2. The upper shell 1 and lower shell 3 are made of a non-flexible material with a certain degree of rigidity (such as molded polymer resin, composite material, etc.). The flexible sidewalls 2, as the name suggests, are made of a flexible material (such as leather, textile fabric, or synthetic fabric). The upper shell 1 includes a top surface 10 and an upper sidewall 11 extending downward along the periphery of the top surface 10. The lower shell 3 includes a bottom surface 30 and a lower sidewall 31 extending upward along the periphery of the bottom surface 30. The upper end of the flexible sidewall 2 is attached to the upper sidewall 11 along the periphery of the upper sidewall 11, while the lower end of the flexible sidewall 2 is attached to the lower sidewall 31 along the periphery of the lower sidewall 31. The connection between the flexible sidewall 2 and the upper and lower sidewalls 11 and 31 is closed, so that the flexible sidewall 2, the upper shell 1, and the lower shell 3 collectively form a case body. The interior of the case body is provided with a storage space for luggage. The attachment method can be fixed or removable. Fixing methods include sewing, heat pressing, riveting, etc., which ensure the case body structure is stable and durable. Removable methods include zippers, buckles, Velcro, etc., allowing for easy removal of the flexible sidewalls 2 for cleaning or replacement.

[0024] This embodiment also includes a number of rigid support rods 4; the support rods 4 are arranged on the inner side of the flexible side wall 2, that is, inside the main body of the box. The two ends of the support rods 4 are rigidly connected to the upper shell 1 and the lower shell 3 respectively. Rigid connection means that the support rods 4 are relatively fixed to the upper and lower shells after installation and cannot move relative to each other. The flexible side wall 2 is tightly attached to the support rods 4, and the support rods 4 provide rigid support for the flexible side wall 2. Alternatively, in some embodiments, the support rods are passed through at least a portion of the flexible side wall; for example, the flexible side wall is a multi-layer composite structure, the support rods pass through the interior of the composite multi-layer structure, and are connected to the upper and lower shells, or the flexible side wall is provided with a sleeveable attachment portion, such as a ring, so that after the support rods pass through the attachment portion of the flexible side wall, they can not only provide rigid support for the flexible side wall, but also have an attachment relationship with it.

[0025] Furthermore, the support rod 4 can be connected directly to the upper shell 1 or lower shell 3, or through some connecting parts. This embodiment employs a connection method in which mounting posts 5 are provided on the inner sidewalls of the upper shell 1 and lower shell 3. These mounting posts 5 have sockets 50 for inserting the support rod 4. The mounting posts 5 are positioned as close as possible to the periphery of the upper sidewall 11 or lower sidewall 31, allowing the support rod 4 to be as close as possible to the flexible sidewall 2 after installation.

[0026] Furthermore, the flexible side wall surface 2 is provided with an opening for communicating with the receiving space; a locking member 20 for opening and closing the receiving space is provided at the opening. The locking member 20 includes a zipper, a button, a Velcro, etc. Furthermore, a combination lock hole 13 is provided on the upper surface of the upper shell 1 for accommodating a combination lock 6; the combination lock 6 and the locking member 20 are locked by a combination. For example, when the locking member 20 is a zipper, the zipper pull head and the combination lock are locked by a combination. The combination lock is a commonly used locking method for existing suitcases and belongs to the prior art. The combination lock and zipper pull head locking technology will not be described in detail here.

[0027] Furthermore, because the upper and lower shells 1 and 3 need to maintain structural strength, their thickness is relatively thick, hindering connection with the flexible sidewalls 2. Therefore, the upper sidewall 11, at its peripheral edge where it connects to the flexible sidewall 2, has an upper extension 12 formed downwardly, thinner than the upper sidewall 11; and the lower sidewall 31, at its peripheral edge where it connects to the flexible sidewall 2, has a lower extension 32 formed upwardly, thinner than the lower sidewall 31. The thinness of the upper and lower extensions 31 and 32 facilitates direct connection to the flexible sidewall 2, or connection to the flexible sidewall 2 via an N-shaped rubber strip.

[0028] Furthermore, rollers 7 are installed on the outer side of the bottom surface of the lower shell 3 to facilitate the user to drag the suitcase.

[0029] Furthermore, the outer side of the top surface 10 is provided with an inwardly recessed handle groove 14, and the bottom of the handle groove 14 is provided with a pull rod hole 15; the inner side of the lower shell 3 is provided with a pull rod mounting seat 33; the pull rod mounting seat 33 is opposite to the pull rod hole 15. Figure 4 As shown, this embodiment adopts a pull rod assembly 8 with a wide pull rod, and the handle groove 14 runs through the length direction of the top surface 10 to facilitate the installation of the pull rod assembly 8. The handle groove 14 is placed in the middle of the top surface 10. Of course, in some embodiments, a narrow pull rod can also be used, and the pull rod groove is located on one side of the top surface. The wide pull rod described in this embodiment refers to a pull rod with a handle length that is almost the same as the length of the box body. Conversely, a narrow pull rod refers to a pull rod handle that is about 10 cm long and is often a pull rod on the back of the box body.

[0030] Furthermore, the perimeter size of the upper side wall 11 is the same as the perimeter size of the lower side wall 12, so that the upper and lower ends of the flexible side wall 2 have equal perimeters, and the box body formed by them is in the shape of a straight cylinder. This design facilitates the cutting and attachment of the flexible side wall 2.

[0031] Those skilled in the art can make various other corresponding changes and deformations based on the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the present utility model.
