Description

Technical Field

[0001] This patent belongs to the technical field of pet supplies, and particularly refers to an expandable pet bag. Background Art

[0002] With the improvement of people's living standards, in order to eliminate loneliness, for entertainment and other spiritual needs, keeping pets at home has become more and more popular. Usually, when pet owners take their pets out for a walk, they generally use a leash to lead the pets. However, if the pet owners are traveling or in a hurry and the pets walk slowly, they need a bag that can hold the pets to facilitate carrying the pets. Therefore, pet bags came into being.

[0003] Existing pet bags usually have a smaller specification for easy carrying and storage. However, in order to increase the activity space of pets, many pet bag producers add zippers on the side of the bag body. The two chains of the zipper are set at a certain distance apart. When the zipper is opened, the bag body expands, and when the zipper is closed, the bag body shrinks, as disclosed in Chinese Patent No. 201410637294.9. However, for the pet bag with this structure, due to the limitation of the fabric between the two chain teeth, the space expansion is extremely limited, and the whole bag is relatively bulky and not easy to carry. Summary of the Invention

[0004] The purpose of this patent is to provide an expandable pet bag with simple expansion and easy to carry.

[0005] The purpose of this patent is achieved as follows:

[0006] An expandable pet bag, comprising:

[0007] A bag body;

[0008] A folding and expanding structure, connected to one side wall of the bag body; the folding and expanding structure has a folded state and an unfolded state; and

[0009] A connecting channel, arranged on one side wall of the bag body facing the folding and expanding structure, for communicating the bag body with the folding and expanding structure;

[0010] Wherein, the folding and expanding structure includes:

[0011] A bottom panel, reversibly arranged on one side wall of the bag body;

[0012] A folding surface, connected between the bottom panel and the bag body; and

[0013] A support assembly, used for supporting the folding surface;

[0014] When the folding and expanding structure is in the folded state, the bottom panel fits against one side wall of the bag body, and the folding surface and the supporting assembly are folded between the bottom panel and the bag body;

[0015] When the folding and expanding structure is in the unfolded state, the bottom panel is laid flat on one side of the bag body, and the folding surface is unfolded under the action of the supporting assembly and is connected to the bottom panel, the supporting assembly and the bag body to form a three-dimensional structure.

[0016] Further, the supporting assembly includes:

[0017] Support panel a, one end of which is flip-connected to the outer end of the bottom panel; and

[0018] A connecting strip, one end of which is fixed on the bottom panel and the other end is detachably connected to the outer side surface of the support panel a, and is used to keep the support panel a in an upright state when the connecting strip is connected to the support panel a.

[0019] Further, an extension part is provided outward at the connection part of the bottom panel with the outside of the support panel a, and the connecting strip is connected to the support panel a through the outer end of the extension part.

[0020] Further, a magic tape is provided at one end of the connecting strip connected to the support panel a, and a first adhesion part corresponding to the magic tape is provided on the support panel a.

[0021] Further, a second adhesion part corresponding to the magic tape is provided on the bag body, and is used to fix the bottom panel on the bag body when the folding and expanding structure is in the folded state.

[0022] Further, a support angle is also flip-mounted on the support panel a. When the support panel a is in the upright state, the support angle flips to be perpendicular to the support panel a and abuts against the extension part.

[0023] Further, the supporting assembly includes:

[0024] Support panel b, one end of which is flip-connected to the outer end of the bottom panel; and

[0025] An elastic support member, which is made of an elastic reset material, and its two ends are respectively connected to the other end of the support panel b and the bag body, and is used to support the support panel b to open outward and keep it vertically arranged when the folding and expanding structure is in the unfolded state.

[0026] Further, the elastic support member includes a first support bar and a second support bar, and the folding surface includes side folding surfaces connected between the first support bar and the bottom panel and between the second support bar and the bottom panel, and a top folding surface connected between the first support bar and the second support bar.

[0027] Further, a shielding portion is also provided in the connection channel. The shielding portion is connected to the bag body through a third zipper assembly and seals the connection channel.

[0028] Further, the shielding portion is flip-connected to one side edge of the connection channel, and a soft pad is provided on one side surface of the shielding portion; by opening the third zipper assembly, the shielding portion is laid flat on the bottom panel, and the side of the shielding portion provided with the soft pad is exposed outward.

[0047] The present patent will be further described below in conjunction with specific embodiments:

[0048] Embodiment 1:

[0049] An expandable pet bag includes a bag body 1, a folding and expanding structure 2, and a connection channel 3;

[0050] Among them, the folding and expanding structure 2 includes:

[0051] A bottom panel 4, which is reversibly arranged on one side wall of the bag body 1;

[0052] A folding panel 5, which is connected between the bottom panel 4 and the bag body 1; and

[0053] A support assembly;

[0054] The folding and expanding structure 2 has a folded state and an unfolded state.

[0055] Such as Figure 1As shown, the bag body 1 in this embodiment is a backpack, which has a shoulder strap part 11 for the user to carry on the back; there is a ventilation hole 12 at the top of the bag body 1, and a front opening 13 is provided at the front end of the bag body 1. A shielding surface 15 is fixed in the front opening 13 through a fourth zipper assembly 14; at the same time, a shielding curtain 16 is also wound above the shielding surface 15. A plurality of side walls are provided on the bag body 1, and the folding and expanding structure 2 is fixed on one of the side walls, and correspondingly, a connecting channel 3 is provided between the folding and expanding structure 2 and the bag body 1.

[0056] As Figure 6 shown, on the side wall of the bag body 1 where the folding and expanding structure 2 is provided, there is a shielding part 31. The shielding part 31 is specifically a square cloth block whose lower side is sewn together with the bag body 1, and the remaining sides of the square cloth block are connected to the bag body 1 through a third zipper assembly 32. When the third zipper assembly 32 is opened, the square cloth block flips towards its lower side, thereby forming the connecting channel 3 on the bag body 1. It should be noted that all the outer edges of the shielding part 31 can be connected to the bag body 1 through the third zipper assembly 32. At this time, the shielding part 31 can be removed through the third zipper assembly 32 to form the connecting channel 3.

[0057] In Variant 1, as Figure 5 shown, the shielding part 31 can also not be provided, and a bare opening can be directly provided to serve as the connecting channel 3, and the connecting channel 3 is blocked by the folding and expanding structure 2 in the folded state.

[0058] As Figure 1 、 2 shown, the bottom panel 4 is supported by a plastic material, and one end of it is connected to the lower end of one side wall of the bag body 1, and it is set to be flipped with the bag body 1 through sewing; at the same time, second zipper assemblies 41 are provided on both sides of the bottom panel 4. When the folding and expanding structure 2 is in the folded state, the bottom panel 4 is connected to the bag body 1 through the second zipper assemblies 41, so that the bottom panel 4 is attached to and fixed on one side wall of the bag body 1; by opening the second zipper assemblies 41, the bottom panel 4 is separated from the bag body 1. After the bottom panel 4 is opened 90 degrees and laid flat, the folding and expanding structure 2 is in the unfolded state, and the folding panel 5 is unfolded into a three-dimensional shape under the action of the support assembly.

[0059] As Figure 3 、 4As shown, the support assembly in this embodiment includes a support frame 631 made of elastic reset material, including a horizontal support rib group 6311 arranged in a "冂" shape in the vertical and horizontal directions and a vertical support rib group arranged vertically; one end of the horizontal support rib group 6311 is connected to the upper end of the bag body 1, and the other end is connected to the vertical support rib group 6312, and the other end of the vertical support rib group 6312 is connected to the outer end of the bottom panel 4. At this time, the bag body 1, the bottom panel 4, the horizontal support rib group 6311 and the vertical support rib group 6312 are connected to form a rectangular body, and a cavity 632 is formed on each surface of the rectangular body. The folding panel 5 includes an elastic gauze, which is arranged in the cavity 632 and connected to the support frame 631 or the bag body 1 or the bottom panel 4.

[0060] The elastic reset material includes a bone, which is elastic and can be bent by applying force, and has reset property and remains vertical when no force is applied. When folding, the folding and expansion structure 2 in this patent overcomes the elasticity of the support frame 631 to fold it into a planar structure, and then connects the bottom panel 4 to one side wall of the bag body 1 through the second zipper assembly 41 to fold the support frame 631 between the bottom panel 4 and the bag body 1. During the folding process, the outer corners of the support frame 631 are driven to move inward, overcome the elasticity of the horizontal support edge group 6311 and the vertical support edge group 6312 to bend, so that the folding panel 5 connected to the support frame 631 is stacked on the bottom panel 4, and then the bottom panel 4 is flipped so that the bottom panel 4 is flush with one side wall of the bag body 1, and then the second zipper assembly 41 is driven to fix. When the folding and expanding structure 2 needs to be opened, the second zipper assembly 41 is first opened to unfold the bottom panel 4 to a horizontal position. At this time, the supporting frame 631 is restored to a three-dimensional state under the action of the elastic restoring material, thereby supporting the folding panel 5 connected to the supporting frame 631 to form a closed three-dimensional shape. At this time, the connecting channel 3 is opened again to connect the bag body 1 to the folding and expanding structure 2, thereby completing the expansion of the pet bag space.

[0061] In this embodiment, the folding and forming of the folding and expanding structure 2 is achieved through the structure of the supporting frame 631 and the bottom panel 4. The structure is easy to unfold and can be unfolded quickly.

[0062] Furthermore, a first zipper assembly 633 is provided between the folding panel 5 and the supporting frame 631. Figure 5 , 6 As shown, the first zipper assembly 633 is provided on the folding panel 5 in the outermost cavity 632 in the support frame 631, and the folding panel 5 is separated from the support frame 631 by the first zipper assembly 633, thereby forming an exit on the outer side of the support frame 631 for the pet to leave the pet bag.

[0063] Furthermore, a soft pad is provided on one side of the shielding portion 31 in this embodiment. By opening the third zipper assembly 32, the shielding portion 31 is laid flat on the bottom panel 4, and the side of the shielding portion 31 with the soft pad is exposed outward. The soft pad can be made of lamb fleece and is used to provide a comfortable seat cushion for pets.

[0064] Embodiment 2:

[0065] As Figure 7 、 8 shown, most of the structures in this embodiment are the same as those in Embodiment 1. The difference lies in that the support assembly includes:

[0066] A support panel a611, one end of which is flip-connected to the outer end of the bottom panel 4; and

[0067] An elastic support member 622, which is made of an elastic reset material and has two ends respectively connected to the other end of the support panel a611 and the bag body 1, and is used to support the support panel a611 to open outward and maintain a vertical setting when the folding and expanding structure 2 is in the unfolded state.

[0068] Among them, the support panel a611, like the bottom panel 4, is made of cloth and can be flip-connected to the outer end of the bottom panel 4 in a sewn form. The elastic support member 622 is specifically a strip-shaped connecting member made of the rubber bone; there are two elastic support members 622, including a first support strip 6221 and a second support strip 6222, which are respectively connected to the bag body 1 on the left and right sides of the support panel a611; at this time, cavities 632 are formed between the two elastic support members 622 and between the elastic support member 622 and the bottom panel 4, and a folding surface 5 is provided in the cavities 632, including side folding surfaces 51 connected between the first support strip 6221 and the bottom panel 4 and between the second support strip 6222 and the bottom panel 4, and a top folding surface 52 connected between the first support strip 6221 and the second support strip 6222, so as to form a folding and expanding structure 2 with a three-dimensional shape.

[0069] When the folding and expanding structure 2 of this structure is folded, the elasticity of the elastic support member 622 is overcome to bend it and overlap it on the bottom panel 4, and then the support panel a611 is flipped to fit it on the bottom panel 4, and then the bottom panel 4 is flipped, and the second zipper assembly 41 on the bottom panel 4 is connected to the bag body 1, and the elastic support member 622 and the support panel a611 are folded between the bottom panel 4 and the bag body 1. When the folding and expanding structure 2 of this structure is unfolded, the second zipper assembly 41 is opened first to open the bottom panel 4, and then the support panel a611 is flipped to a vertical state. While flipping the support panel a611, an initial force of resetting is given to the elastic support member 622 to reset and stretch the elastic support member 622, so as to support the support panel a611 to keep it in a vertical state.

[0070] This embodiment adopts the support panel a611 as the support component. Compared with the support frame 631 structure in Embodiment 1, the support effect brought by the support panel a611 is better and more stable, and is not easy to tip over.

[0071] Embodiment 3:

[0072] Most of the structures of this embodiment are the same as those of the second embodiment, and it also has the support panel b621, but the difference is that the elastic support member 622 is not provided in this embodiment, and the support panel b621 is supported by a connecting strip 612 structure; specifically, one end of the connecting strip 612 is fixed to the bottom panel 4, and the other end is detachably connected to the outer side of the support panel b621, so as to keep the support panel b621 in a vertical state when the connecting strip 612 is connected to the support panel b621. At this time, the folding surface 5 is an integrated foldable partition net whose outer edges are respectively connected to the bag body 1, the support panel a611 and the bottom panel 4.

[0073] like Figure 10As shown, an extension part 613 is provided outside the connection of the bottom panel 4 with the support panel b621. The connecting strip 612 is connected to the support panel b621 through the outer end of the extension part 613; the extension part 613 can be obtained by selecting the connection position between the support panel b621 and the bottom panel 4. The connecting strip 612 is made of cloth, one end of which is fixed on the lower side of the bottom panel 4 by sewing, and the other end is bent upward to connect the support panel b621; by setting the length of the connecting strip 612, when the connecting strip 612 is connected to the support panel b621, the connecting strip 612 abuts against the outer end of the extension part 613. When the support panel b621 is tilted inward, the connection will abut against the outer end of the extension part 613 for positioning, so that the connecting strip 612 pulls the support panel b621 to keep it in an open state; at this time, the support panel b621, the extension part 613 and the connecting strip 612 form a structurally stable triangle, and the support triangle brought by the structure of the extension part 613 is used to keep the support panel b621 stable.

[0074] Specifically, a magic tape is provided at one end of the connecting strip 612 connected to the support panel b621, and a first adhesion part 615 corresponding to the magic tape is provided on the support panel b621. The connecting strip 612 is connected to the support panel b621 by means of adhesion of the magic tape. The magic tape form has the advantage of quick disassembly and assembly.

[0075] When the folding and expanding structure 2 is folded, by unfastening the connecting strip 612, then folding the support panel b621 and the bottom panel 4 in sequence, and connecting the bag body 1 and the bottom panel 4 through the second zipper assembly 41 provided on the bottom panel 4; since the elastic support member 622 is not provided, the folding and expanding structure 2 in this embodiment is easier to fold, and there is no need to consider the placement problem of the rigid elastic support member 622.

[0076] Furthermore, as Figure 9 shown, a second adhesion part 616 corresponding to the magic tape is provided on the bag body 1. When the bottom panel 4 is turned over to fit with the bag body 1, the second adhesion part 616 is adhered by the magic tape on the connecting strip 612 to fix the bottom panel 4 on the bag body 1, which cleverly utilizes the detachable structure of the connecting strip 612, so that one connection method can meet multiple connection requirements.

[0077] Furthermore, as Figure 10 、 11As shown, a support angle 617 is also flip - installed on the support panel b621. The support angle 617 is made of fabric and is in the shape of a right - angled triangle as a whole. It is flip - installed on the side of the support panel b621 facing the extension 613 by sewing. When the support panel b621 is in a vertical state, the support angle 617 is flipped so that it is perpendicular to the support panel b621 and the extension 613. At this time, the support panel b621 is limited from flipping on one side by the connecting strip 612 and is limited from flipping on the other side by the support angle 617, so that the support panel b621 is more stable and not easily toppled, and thus the overall structure of the folding and expanding structure 2 is stable.

[0078] The above - mentioned embodiments are only the preferred embodiments of this patent, and do not limit the protection scope of this patent accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this patent should be covered within the protection scope of this patent.
