Abstract
Description
Technical Field
[0001] This utility model belongs to the field of luggage technology, and in particular relates to a suitcase. Background Technology
[0002] Currently, most suitcase handles on the market are either directly mounted on the surface of the suitcase or have a recess larger than the handle created in the shell and fitted into that recess. Surface mounting increases the overall size of the suitcase, necessitating a reduction in the effective volume during the design phase to meet carry-on standards. Recessed mounting requires a gap between the handle and the shell to allow fingers to easily reach in and remove it, creating a strip-shaped indentation on the shell. This indentation makes the suitcase prone to dust accumulation and difficult to clean, while also affecting its aesthetic appeal. Furthermore, these deep indentations are more difficult to manufacture, requiring complex molds and resulting in higher development costs. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a suitcase that solves the problem of dust accumulation and difficulty in cleaning at the handle of the existing recessed handle installation method.
[0004] To solve the above problems, the technical solution of this utility model is as follows:

[0030] The present invention provides a suitcase in further detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims.
[0031] See Figures 1 to 8 In one embodiment, a suitcase includes a body and a handle.
[0032] The top surface of the housing has a handle mounting recess. The handle portion includes a handle mounting shell and a handle body. The handle body is mounted in the handle mounting recess via the handle mounting shell and is configured to switch between a folded configuration and a raised configuration. In the folded configuration, the handle body is located within the handle mounting recess; in the raised configuration, at least a portion of the handle body extends upward beyond the handle mounting recess.
[0033] The handle body has at least one recessed groove, and the handle also includes a flexible cover that covers the top surface of the handle body and the recessed groove, with the edge of the flexible cover fitting into the handle mounting recess. The flexible cover is configured to deform under external force and enter the recessed groove to form an operating space within the handle mounting recess. Furthermore, in the folded configuration, the flexible cover does not protrude from the top surface of the housing.
[0034] This embodiment features a handle mounting recess on the top surface of the case, into which the handle body is installed via a handle mounting shell. The handle body can move relative to the recess, switching between a folded and raised configuration. A recessed groove and a flexible cover are provided on the handle body, which covers the handle body and the recessed groove and fits snugly against the edge of the recessed cavity. When the bag needs to be lifted, the operator presses the flexible cover into the corresponding recessed area to raise the handle body to the raised configuration. Furthermore, the flexible cover fits seamlessly into the recessed cavity, eliminating gaps. Therefore, when not in use, dust only accumulates on the top surface of the case and the flexible cover, preventing it from entering the narrow lower area. This facilitates cleaning and solves the problem of dust accumulation and difficulty in cleaning existing recessed handle mounting methods.
[0035] Furthermore, this embodiment achieves a smooth, flush fit between the handle and the top surface of the suitcase through the use of a flexible cover, thereby maximizing the internal volume of the suitcase within the carry-on size requirements and resulting in a more aesthetically pleasing overall appearance. Additionally, it reduces the difficulty of creating the recessed shell and lowers development costs.
[0036] The specific structure of the suitcase in this embodiment will be further explained below:
[0037] In this embodiment, the thickness of the flexible cover gradually decreases from the handle body toward the edge of the handle mounting cavity. The purpose of gradually decreasing the thickness is to allow it to fit seamlessly with the rounded corner of the top surface of the housing at the handle mounting recess.
[0038] In this embodiment, the handle body includes a grip section and connecting extension sections connected to both sides of the grip section, and the connecting extension sections are slidably connected to the handle mounting shell.
[0039] Specifically, the connecting extension section is provided with a sliding groove, and the handle mounting shell is provided with a corresponding connecting post. The connecting extension section is fitted onto the corresponding connecting post through the sliding groove. The length of the sliding groove is the distance that the connecting extension section and the grip section can move relative to the connecting post and the housing.
[0040] In this embodiment, there is a single clearance groove, located on one side along the length of the grip section, forming a narrow middle section and two wide end sections at both ends along the length of the narrow middle section, i.e., a shape that is narrow in the middle and wide on both sides. The width difference between the clearance groove and the wide end sections in the width direction is used to insert and pry out the grip section for use.
[0041] In other embodiments, there may be two clearance grooves, which are respectively opened on both sides of the grip section in the length direction to form a narrow middle section and two wide end sections located at both ends in the length direction of the narrow middle section, which are also narrow in the middle and wide on both sides.
[0042] In this embodiment, the handle mounting housing includes two handle seats and two inner covers. The handle seats and corresponding inner covers are fitted together and clamped to the bottom surface of the handle mounting recess, forming the aforementioned connecting posts. Specifically, there can be two connecting posts. The handle seats and corresponding inner covers can be connected by providing openings in the housing shell and using bolts.
[0043] In this embodiment, the handle body can be injection molded. As the main force-bearing structure of the handle, the flexible cover is a soft rubber that is injection molded onto the handle body. The soft rubber covers the grip section and is used to cover the appearance of the handle into a uniform plane.
[0044] The processing steps of the suitcase in this embodiment are as follows: 1. Vacuum-form the suitcase body (shell) into a suitable groove shape (the groove shape is the handle mounting recess mentioned above), and drill holes in a suitable position; 2. Inject-mold the handle body, and then inject-mold it with soft handle rubber; 3. Insert the left and right handle seats into the sliding grooves of the connecting extension sections on both sides of the handle body; 4. Insert the above assembly into the pre-drilled holes in the suitcase shell from the outside, then cover the left and right seat inner covers from the inside, and fix them with bolts to complete the installation.
[0045] This embodiment of the suitcase optimizes existing handle designs by using a recessed handle that allows for a completely flat outer surface. This maximizes the internal volume of the suitcase within the required size constraints without significantly complicating the manufacturing process of the shell. The perfectly fitted shape is less prone to dust accumulation and easier to clean than traditional grooved designs.
[0046] 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.
