Zipper component 3. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Example 1 like Figures 1 to 4 As shown, a pet pack extension structure in this embodiment includes a main pack 1 and an extension pack 2.

[0020] The main package 1 has a main cavity 11, and the main cavity 11 has a side opening 111 on its side. In this embodiment, the main package 1 takes an approximately rounded rectangular body structure as an example. The side opening 111 is located on the back side of the main package 1. At the same time, the top and front of the main package 1 can also be provided with an entrance 112 that connects to the main cavity 11. Each entrance 112 is provided with an openable and closable cover 113 to facilitate putting the pet in through the entrance 112.

[0021] The main bag 1 in this embodiment is also provided with a handle 12 at the top rear side, a shoulder strap 13 at the rear side, and ventilation windows 14 and storage bags 15 on the left and right sides, so that the pet bag can be carried or worn when going out and the pet can be ventilated.

[0022] The expansion package 2 is connected to the side opening 111 and can be unfolded and folded. When unfolded, it forms an expansion cavity 21 that communicates with the side opening 111. The space of the expansion cavity 21 is larger than the space of the main cavity 11, and the width of the expansion cavity 21 is larger than the width of the side opening 111 and the width of the main cavity 11. The expansion cavity 21 has an expansion area 211 facing the side opening 111 and an expansion area 212 located laterally to the expansion area 211.

[0023] This embodiment significantly enlarges the size of the expansion pack 2, so that it is not limited to the area directly opposite the side opening 111, but extends to an additional expansion area 212 located to the side of the side opening 111. This allows the space of the expansion cavity 21 inside the expansion pack 2 to be larger than the space of the main cavity 11, providing more space for the pet to move around and meeting the user's needs.

[0024] The expansion package 2 in this embodiment includes a flexible support frame 22 and flexible fabric 23 connected to each side of the flexible support frame 22; the flexible fabric 23 can be a breathable mesh fabric to facilitate ventilation and observation.

[0025] The flexible support frame 22 has six sides: front, back, left, right, top, and bottom. The flexible fabric 23 on the rear side of the flexible support frame 22 is connected to the side opening 111 and has an expansion opening 24 corresponding to the side opening 111. The expansion opening 24 directly connects to the expansion area 211. Specifically, the edge of the expansion opening 24 can be sewn and fixed to the edge of the side opening 111 to achieve the connection between the expansion bag 2 and the main bag 1.

[0026] By setting up the flexible support frame 22 and the flexible fabric 23, the expansion pack 2 can be easily unfolded and folded. When the expansion capacity is not needed, the flexible support frame 22 and the flexible fabric 23 can be bent and stored in the side opening 111.

[0027] Specifically, the flexible support frame 22 in this embodiment may include a rectangular front frame rib 221 located on the front side, and four support ribs 222 connected to the rear sides of the four corners of the front frame rib 221 and located between the top, bottom, left, and right sides; the rear side of the flexible support frame 22 does not have ribs. Since the size of the expansion pack 2 is larger than the size of the side opening 111, the number of ribs can be reduced by omitting the ribs on the rear side, which facilitates bending of the expansion pack 2 when it is closed, making it easier to put into the side opening 111, while ensuring that the expansion pack 2 has sufficient support when it is unfolded.

[0028] The material of the ribs can refer to existing technologies.

[0029] In this embodiment, the area of ​​the flexible fabric 23 on the rear side of the flexible support frame 22 without the expansion opening 24 is also combined with a flap 16; one side of the flap 16 is rotatably connected to one side of the side opening 111, and the other side is detachably connected to the remaining edge of the side opening 111, for closing the side opening 111 after the expansion bag 2 is stored; the other side of the flap 16 is detachably connected to the edge of the side opening 111 through the zipper assembly 3.

[0030] For details, please refer to Figure 4In this embodiment, the expansion opening 24 can be located in the middle of the flexible fabric 23 on the rear side of the flexible support frame 22; the expansion cavity 21 has two expansion areas 212 located on the left and right sides of the expansion area 211, respectively.

[0031] The extended opening 24 has a flip cover 16 on each of its left and right sides. The two flip covers 16 are movably fastened together to simultaneously close the openings 111 on the opposite sides.

[0032] By incorporating the flip-top 16, the side opening 111 can be closed while storing the expansion pack 2. Moreover, the flip-top 16 is directly attached to the rear side of the expansion pack 2, providing some support when closing. That is, the flip-top 16 can be used as a support base to press and bend the ribs, and then flip the flip-top 16 to move the ribs and flexible fabric 23, directly inserting the expansion pack 2 into the side opening 111. This makes it more convenient to use and solves the problem of the expansion pack 2 being difficult to close when it is too large.

[0033] In this embodiment, a fastener 161 extends from one of the right-side flip-up panels 16 toward the other right-side flip-up panel 16, and a Velcro assembly (not shown) is provided between the fastener 161 and the other flip-up panel 16.

[0034] Therefore, after the two flaps 16 are connected to the side openings 111 via the zipper assembly 3, they can be further fastened with Velcro to improve structural stability.

[0035] In this embodiment, the flexible fabric 23 on the front side of the flexible support frame 22 is also provided with an opening 25, and an openable and closable door panel 26 is provided at the opening 25. The door panel 26 can be detachably connected to the opening 25 through the zipper assembly 3. After the door panel 26 is opened, it is convenient for the pet to enter the expansion cavity 21 through the opening 25.

[0036] Example 2 like Figure 5 and Figure 6 As shown, the structure of this embodiment is basically the same as that of the above embodiments. The main difference is that the extended opening 24 is provided on the left or right side of the flexible fabric 23 on the rear side of the flexible support frame 22 in this embodiment.

[0037] This embodiment uses the example of an expansion opening 24 on the right side for illustration. Correspondingly, the expansion cavity 21 in this embodiment has an expansion area 212 located to the left of the expansion area 211.

[0038] Meanwhile, in this embodiment, only one flip cover plate 16 needs to be provided on the other side of the extended opening 24. The flip cover plate 16 can also be movably fastened to close the opening 111 on the opposite side.

[0039] This indicates that the location of the extended opening 24 is not limited to that of this embodiment.
