Abstract
Description
Technical Field
[0001] This utility model relates to the field of handbag technology, and in particular to an expandable and stretchable handbag. Background Technology
[0002] Traditional handbags have a fixed capacity, making them difficult to hold many items while appearing bulky when carrying few, thus failing to meet diverse storage needs. Their fixed carrying space limits their flexibility for shopping or travel, resulting in a poor user experience.
[0003] Some existing expandable handbags are prone to jamming when unfolded and stretched, and their structure is loose and unstable after expansion. When folded, the creases are obvious, the appearance is not neat, and there is a lack of effective restraint structure. They are also prone to deformation when expanded, making it difficult to balance practicality and aesthetics. Utility Model Content
[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an expandable and stretchable handbag that can be flexibly expanded and stretched to increase its capacity. After being expanded, the structure is stable and not easy to loosen. It is suitable for repeated stretching and use, and is easy to operate, taking into account both portability and storage needs.
[0005] This utility model also provides a tote bag with the above-mentioned unfoldable and stretchable design, including a main fabric body for the bag, with side folded fabrics fixedly connected to both sides of the main fabric body, and side stretchable adjustment fabrics movably connected to the sides of the side folded fabrics, with symmetrical long strips of hook and loop fasteners fixedly connected to the sides of the main fabric body, and symmetrical short strips of hook and loop fasteners fixedly connected to the inner side of the side stretchable adjustment fabrics.
[0006] According to the present invention, the unfoldable and stretchable handbag has a corresponding pull handle fixedly connected to both ends of the main fabric body of the handbag.
[0007] According to the present invention, the expandable and stretchable handbag has a plurality of symmetrical connecting holes at one end of the side stretchable adjustment fabric and at the other side of the main fabric body of the handbag, and a first sewing thread is movably connected through the corresponding connecting holes.
[0008] According to the present invention, in the expandable and stretchable handbag, the long strip of hook and loop fastener is correspondingly and movably connected to the short strip of hook and loop fastener.
[0009] According to the present invention, the unfoldable and stretchable handbag has multiple symmetrical connecting buttons that are movably connected between the long strips of Velcro, and a second sewing thread is movably connected through the side of the main fabric body of the handbag and the corresponding connecting buttons.
[0010] According to the present invention, the unfoldable tote bag has a hanging rope fixedly connected between the short hook and loop fasteners, and symmetrical reinforcing sewn fabric is fixedly connected to the inner side of the side stretch adjustable fabric. The two ends of the hanging rope are fixedly connected to the reinforcing sewn fabric.
[0011] According to the present invention, in the expandable and stretchable handbag, the hanging rope is correspondingly and movably connected to the connecting button.
[0012] Beneficial effects: 1. The unfoldable and stretchable handbag of this technical solution uses side folding fabric and side stretching adjustment fabric to flexibly unfold and stretch to expand its capacity. Long strip hook and loop fasteners and short strip hook and loop fasteners, connecting buttons and hanging ropes provide double fixation. After unfolding, the structure is stable and not easy to loosen.
[0013] 2. The fixed sewn fabric is reinforced to strengthen the hanging rope connection. The first and second sewing lines improve the overall sturdiness and are suitable for repeated stretching. It is easy to operate and can quickly switch between shrinking and unfolding states, taking into account both portability and storage needs. Attached Figure Description

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0017] Reference Figure 1-6 This utility model embodiment is an unfoldable stretchable handbag, which includes a main fabric body 1 for the handbag, and side folded fabric 2 for the handbag on both sides of the main fabric body 1. Side stretchable adjustment fabric 4 is movably connected to the side of the side folded fabric 2. Symmetrical long strips of hook and loop fastener 5 are fixedly connected to the side of the main fabric body 1. Symmetrical short strips of hook and loop fastener 7 are fixedly connected to the inner side of the side stretchable adjustment fabric 4. The two work together to achieve a fixed state.
[0018] Specifically, the two ends of the main fabric body 1 of the handbag are fixedly connected with a lifting handle 3. The lifting handle 3 is convenient for the user to hold and carry. Its connection position avoids the stretching area and does not affect the unfolding and shrinking function of the handbag.
[0019] Specifically, a plurality of symmetrical connecting holes 12 are provided on one end of the side stretch adjustment fabric 4 and the other side of the main fabric body 1 of the bag. A first sewing thread 6 is connected through the corresponding connecting hole 12. By sewing the first sewing thread 6, the side stretch adjustment fabric 4 is firmly connected to the main fabric body 1 of the bag, so as to prevent it from falling off when stretched.
[0020] Specifically, the long strip of hook and loop fastener 5 is connected to the short strip of hook and loop fastener 7. By attaching and separating the hook and loop sides, the handbag can be quickly locked in its retracted or unfolded state, making it easy to operate.
[0021] Specifically, multiple symmetrical connecting buttons 10 are movable between the long strips of Velcro 5, and a second sewing thread 11 is movablely connected through the sides of the main fabric body 1 of the bag and the corresponding connecting buttons 10 to ensure that it does not loosen during use.
[0022] Specifically, the corresponding fixed connections between the short hook and loop fasteners 7 are hanging cords 9, and the corresponding fixed connections on the inner side of the side stretch adjustment fabric 4 are symmetrical reinforced fixed sewn fabrics 8. The two ends of the hanging cords 9 are correspondingly fixed to the reinforced fixed sewn fabrics 8, making the connection of the hanging cords 9 more stable and less likely to be pulled off.
[0023] Specifically, the lanyard 9 is attached to the connecting button 10, and together with the long strip of hook-and-loop fastener 5 and the short strip of hook-and-loop fastener 7, it forms a double limit, making the unfolded state more stable and preventing accidental shrinkage during use.
[0024] Working principle: Fold the side folded fabric 2 of the bag up, attach the long loop fastener 5 and the short hook fastener 7 together, and let the hanging rope 9 hang naturally. The overall size of the bag is compact, suitable for storing a small number of items. Separate the long loop fastener 5 and the short hook fastener 7, and stretch the side folded fabric 2 of the bag outward. The side stretching adjustment fabric 4 will extend accordingly, increasing the storage space of the bag. Connect the hanging rope 9 to the connecting button 10, and then reattach the long loop fastener 5 and the short hook fastener 7. This double-locking mechanism secures the bag in its unfolded state and prevents accidental shrinkage. Unfasten the hanging rope 9 from the connecting button 10, separate the fasteners, fold the side folded fabric 2 of the bag inward, and reattach the fasteners to lock them in place. The bag returns to its folded state.
[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
