Description

Technical Field

[0001] The present invention relates to the technical field of pet supplies, and particularly to a pet backpack and a method for loading a pet using the pet backpack. Background Art

[0002] With pets increasingly integrated into family life, keeping pets has become a common trend. As a result, there are more and more scenarios where pet owners take their pets out and participate in various activities together, which significantly increases the demand for convenient and safe tools for carrying pets when going out. In the prior art, pet backpacks generally include two types: hard-shell backpacks made of rigid plastic shells and soft-shell backpacks made of flexible materials. Although hard-shell backpacks have a more spacious internal space, soft-shell backpacks are the first choice for many pet owners because of their light weight and foldable characteristics, which make them more convenient to carry. Such backpacks are equipment specifically designed for transporting pets, and they are considered in terms of structure and materials. Commonly used breathable and durable materials, such as common nylon, canvas or Oxford cloth, are usually adopted to ensure that pets can stay comfortable and dry inside the backpack. Many designs also include an opening at the top to facilitate the pet to poke its head out, observe the environment and breathe freely, which is particularly important for reducing the anxiety of pets in a closed space.

[0003] However, in actual use, existing soft-shell pet backpacks still have some significant limitations, especially in terms of usability and safety. First of all, the process of putting a pet into the backpack is often not convenient enough, especially for larger pets or those not used to the backpack environment. The opening design of existing backpacks is often not spacious enough or in an ideal position, making it difficult for the owner to easily and quickly hold or guide the pet into the backpack, increasing the operation difficulty and the discomfort of the pet. Secondly, the safety structure of the opening at the top of the backpack needs to be improved. Although it is convenient for the pet to poke its head out, it also provides an opportunity for lively or nervous pets to break free. A simple buckle structure may not be able to effectively prevent the pet from struggling to escape. Once a break-free incident occurs in a public place, it may lead to the loss of the pet or pose a danger, causing potential safety hazards. These pain points indicate that the design of pet backpacks still needs to be innovated and optimized in terms of structure. Summary of the Invention

[0038] To further illustrate each embodiment, the present invention provides accompanying drawings. These drawings are a part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used to explain the operating principle of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0039] The present invention will now be further described in conjunction with the accompanying drawings and specific implementation manners.

[0040] As Figure 1-8As shown, this embodiment provides a pet backpack 1, including a backpack body 10, which is configured to carry a pet therein. An internal compartment for accommodating a pet is formed inside the backpack body 10. The backpack body 10 includes a bottom 101 and a peripheral wall surface 102 extending upward from the bottom 101. The peripheral wall surface 102 includes a front panel portion 11, side panel portions 12, 14, and a rear panel portion 13. The front panel portion 11, side panel portions 12, 14, rear panel portion 13, and bottom 19 of the backpack body 10 can be formed separately and can be connected to each other during the manufacturing process, for example, by stitching, by an adhesive, or by fabric welding. In other embodiments, one or more of the front panel portion 11, side panel portions 12, 14, rear panel portion 13, and bottom 19 of the backpack body 10 can be formed as a single piece (i.e., an integral structure). For example, the front panel portion 11, side panel portions 12, 14, rear panel portion 13, and bottom 19 of the backpack body 10 are respectively single panel materials. Or, in other embodiments, the front panel portion 11, side panel portions 12, 14, and rear panel portion 13 of the backpack body 10 are respectively single panel materials, and each single panel material extends downward to form the bottom 19 of the backpack body 10. The bottom 19 can be a flat-bottom structure or a pointed-bottom structure. The backpack body 10 can be formed of any suitable material, including natural or synthetic materials. For example, the backpack body 10 can be made of soft nylon fabric.

[0041] A shoulder strap 41 is connected to the backpack body 10. Specifically, in this embodiment, the shoulder strap 41 is connected to the rear panel portion 13 of the backpack body 10 to facilitate carrying the backpack 1 on the user's shoulder. In some examples, a chest strap 42 can be provided on the shoulder strap 41 and a support piece can be embedded in the rear panel portion 13 to make the entire backpack more stable on the human body and reduce the shaking of the backpack during walking. Especially during more intense activities, a stable carrying effect can be provided.

[0042] In some other embodiments, as Figure 5 shown, a waist fixing strap 43 is further connected to the lower part of the rear panel portion 13. The waist fixing strap 43 can fix the lower part of the backpack 1 to the human waist, thereby redistributing the weight of the backpack from the shoulders to the hips, being able to carry a heavier load, and further enhancing the stability of the backpack 1 on the human body.

[0043] The backpack body 10 is provided with an upper opening 15, which is configured to enable the head of the animal placed inside the backpack 1 to protrude, so that the pet can see its surrounding environment well and breathe freely, improving the comfort and sense of security of the pet.

[0044] The peripheral wall surface 102 of the backpack main body 10 is provided with two strip-shaped closures 5 arranged at intervals. Both of the two strip-shaped closures 5 extend from the edge of the upper opening 15 towards the bottom 101 of the backpack main body 10 to form an openable flap portion 103. As shown in Figure 2-Figure 3 , when the backpack main body 10 is opened at the two strip-shaped closures 5, the flap portion 103 can be folded downwards to form a side opening 18 communicating with the upper opening 15. Specifically, in this embodiment, the two strip-shaped closures 5 are a first zipper 16 and a second zipper 17. Both the first zipper 16 and the second zipper 17 extend from the edge of the upper opening 15 towards the bottom 101 of the backpack main body 10 to form an openable flap portion 103. As shown in Figure 3 , when the first zipper 16 and the second zipper 17 are opened, the flap portion 103 of the backpack main body 10 can be folded downwards to form a side opening 18 communicating with the upper opening 15. Due to the above settings, a larger opening of the backpack main body can be formed on the backpack main body 10 by the upper opening 15 and the side opening 18, which will be more convenient when a pet is put into the backpack 1 through the opening of the backpack main body, and is particularly beneficial for putting a pet with a larger body size or not accustomed to the backpack environment into the backpack 1. In other embodiments, the strip-shaped closure 5 can also be a plurality of snap fasteners arranged vertically, or a binding rope, a magic tape, etc.

[0045] Furthermore, as shown in Figure 2-Figure 3 , the first zipper 16 and the second zipper 17 extend substantially along the longitudinal direction, and the first zipper 16 and the second zipper 17 are arranged substantially in parallel, so that when the first zipper 16 and the second zipper 17 are opened, the backpack main body 10 can form a flap portion 103 substantially in a rectangular shape, so that a side opening 18 as large as possible can be formed on the backpack main body 10, which is more conducive to putting a pet into the backpack 1. Of course, in other embodiments, for the body shapes of different pets, it can also be designed to adopt two zippers arranged in a V shape and the corresponding triangular or trapezoidal flap portions.

[0046] In this embodiment, specifically, the first zipper 16 and the second zipper 17 are located on both sides of the front panel portion 11 and serve as the connection structure between the front panel portion 11 and the side panel portions 12, 14, so that the structure is simpler and the overall appearance is more beautiful. In this embodiment, the front panel portion 11 serves as the flap portion 103. In some other embodiments, the first zipper 16 and the second zipper 17 can be arranged at other positions of the backpack main body 10, as long as there is a sufficient interval between the first zipper 16 and the second zipper 17 to form a side opening 18 large enough for a pet to pass through.

[0047] Referring to Figure 2-Figure 4, in this embodiment, a collar assembly 20 is provided inside the backpack main body 10. The collar assembly 20 is detachably connected to two positions on the peripheral wall surface 102 of the backpack main body 10. Specifically, the collar assembly 20 is connected to the inner side walls of the front panel portion 11 and the rear panel portion 13. The collar assembly 20 is used to be sleeved on the neck of a pet, so that the pet can be stably held in the backpack 1. And because the collar assembly 20 is connected to two positions of the backpack main body 10, the collar assembly 20 can be first fixed to the neck of the pet, and then the collar assembly 20 is detachably connected to at least two positions of the backpack main body 10. This is not only more suitable for the loading operation of the pet, but also can effectively ensure the stability after loading, and can effectively prevent the pet from struggling and escaping outside the backpack 1, ensuring the safety of the pet. In other embodiments, the collar assembly 20 is connected to three or more positions on the peripheral wall surface 102 of the backpack main body 10, so that the collar assembly 20 can be more firmly connected to the backpack main body 10. However, this also brings the problem of more cumbersome operation. Therefore, connecting the collar assembly 20 to two positions on the peripheral wall surface 102 of the backpack main body 10 is a better implementation scheme.

[0048] In this embodiment, the collar assembly 20 is detachably connected to two opposite inner side walls of the backpack main body 10, and the force-bearing condition of the collar assembly 20 is more reasonable, and the effect of preventing the pet from struggling and escaping is better. Of course, in some other embodiments, it is also a feasible technical solution that the collar assembly 20 is connected to two adjacent inner side walls of the backpack main body 10.

[0049] In this embodiment, the collar assembly 20 includes a collar body 22 and two first connectors 21 fixedly arranged on the collar body 22. The collar body 22 is a ring structure and is used to be sleeved on the neck of a pet. Second connectors 23 are respectively arranged at two positions on the peripheral wall surface 102 of the backpack main body 10, and the detachable connection between the collar assembly 20 and the backpack main body 10 is realized by whether the first connectors 21 and the second connectors 23 are connected or not.

[0050] Refer to Figure 2-Figure 4 , the first connector 21 is a hanging ring 21, and the second connector 23 is a spring buckle 23. The spring buckle 23 is fixed to the peripheral wall surface 102 of the backpack main body 10 through a flexible band 25. The flexible band 25 can provide a movement space for the movement of the pet's head and improve the comfort of the pet when wearing.

[0051] The flexible belt 25 can be a strap or a rope, which can be adjusted in length in cooperation with an adjustment buckle, can be adapted to pets of different body sizes, and has a firm connection. Alternatively, the flexible belt 25 can be an elastic cord or a spring. The flexible belt 25 made of the elastic cord or the spring can adapt to pets of different body sizes due to its own elasticity, making it more convenient to use. Moreover, the flexible belt 25 made of the elastic cord or the spring forms a traction force on the collar assembly 20, and the fixation of the pet is more firm. In this embodiment, the hanging ring 21 is a D-shaped ring, so that the side facing the pet is relatively flat, which can improve the comfort of the pet when wearing.

[0052] In this embodiment, the number of the first connectors 21 and the second connectors 23 is two. The two second connectors 23 are respectively connected to the inner side walls of the front panel portion 11 and the rear panel portion 13 opposite thereto. Since the front panel portion 11 can be turned over and opened, after the first zipper 16 and the second zipper 17 are zipped up, the second connector 23 on the inner side wall of the front panel portion 11 can be connected to the corresponding first connector 21 on the collar assembly 20, without having to connect all the second connectors 23 and the first connectors 21 prematurely, reducing the time the pet is restricted and being beneficial to improving the comfort of the pet.

[0053] Refer to Figure 2-Figure 4 , an inner fixing belt 24 is further provided inside the backpack main body 10 near the bottom 101. The inner fixing belt 24 is used to fix the body of the pet inside the backpack main body 10, and can further prevent the pet from struggling and escaping.

[0054] Refer to Figure 1-Figure 4, since the first zipper 16 and the second zipper 17 are provided on the backpack body 10, a larger opening of the backpack body can be formed, which also leads to the possibility of a certain degree of decline in the overall structural strength of the backpack body 10. Therefore, it is necessary to strengthen the structure at the positions of the first zipper 16 and the second zipper 17 to prevent the zippers from being accidentally opened due to the activities of the pet. For this purpose, an upper support belt 31 near the upper opening 15 and a middle support belt 32 located between the upper opening 15 and the bottom 101 are also provided on the backpack body 10. The upper support belt 31 and the middle support belt 32 are used to strengthen the connection strength of the first zipper 16 or the second zipper 17. There are two upper support belts 31 and two middle support belts 32 respectively. Both ends of the upper support belt 31 and the middle support belt 32 are respectively connected to both sides of the first zipper 16 or the second zipper 17. The upper support belt 31 and the middle support belt 32 are both detachable and separable structures, for example, they can be detachably separated by buckles. When the first zipper 16 and the second zipper 17 are zipped up, the upper support belt 31 and the middle support belt 32 are fastened. The upper support belt 31 can strengthen the connection strength of the first zipper 16 and the second zipper 17 at the upper opening 15, and the middle support belt 32 can further strengthen the connection strength of the first zipper 16 and the second zipper 17 in the middle, thereby strengthening the overall strength of the backpack 1 and further improving the safety of the pet. Of course, in some other embodiments, only the upper support belt 31 may be provided.

[0055] Referring to Figure 1-Figure 4 , a handle 35 is connected to the outer side of the front panel portion 11 of the backpack body 10, so that the backpack 1 can be carried by hand through the handle 35, which is convenient for moving the backpack. A storage bag 36 is also connected to the outer side of the front panel portion 11 of the backpack body 10. The storage bag 36 can be used to store some pet supplies, greatly improving the convenience of traveling.

[0056] In some embodiments, the backpack body 10 is further connected with a top cover (not shown). The top cover is made of a transparent material and can be breathable. For example, the top cover is provided with air holes to achieve the breathable function. The top cover is used to cover the upper opening 15, so as to provide a shielding and protection function for the pet's head, improving the safety of the pet from surrounding pedestrians.

[0057] Referring to Figure 1-Figure 8 , especially referring to Figure 6-Figure 8 , this embodiment also provides a method for loading a pet using the pet backpack 1, including the following steps:

[0058] S1: Provide the pet backpack 1 as described above;

[0059] S2: Unfasten the upper support strap 31 and the middle support strap 32 on the backpack body 10, open the first zipper 16 and the second zipper 17 which are spaced apart from each other on the backpack body 10, and turn over the front panel portion 11 so that a side opening 18 is formed on the backpack body 10;

[0060] S3: Put on the collar body 22 around the neck of the pet 2, put the pet 2 into the backpack body 10 through the side opening 18, and fasten the body of the pet 2 inside the backpack body 10 with the inner fixing strap 24, as Figure 6 shown;

[0061] S4: Connect the collar body 22 with the first hook 21 on the first inner side wall of the backpack body 10. Then, at least partially zip up the first zipper 16 and the second zipper 17 so that the upper end of the front panel portion 11 is close to the collar body 22. Then, connect the second hook 23 on the inner side wall of the front panel portion 11 with the collar body 22, as Figure 7 shown.

[0062] S5: After the first zipper 16 and the second zipper 17 are completely zipped up, fasten the upper support strap 31 and the middle support strap 32, and then the loading of the pet into the pet backpack 1 is completed, as Figure 8 shown.

[0063] Through the above steps, the pet can be stably held in the backpack 1. Since the first zipper 16 and the second zipper 17 are provided on the backpack body 10, a relatively large side opening 18 can be formed on the backpack body 10, which is more convenient for the pet to be put into the backpack 1 through the side opening 18, especially beneficial for larger pets or pets not used to the backpack environment to be put into the backpack 1; and since the collar assembly 20 is connected to the two inner side walls of the backpack body 10, it can effectively prevent the pet from struggling and escaping outside the backpack 1, ensuring the safety of the pet.

[0064] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them fall within the protection scope of the present invention.
