Description

Technical Field

[0006] , , , , ,

[0001] The present invention relates to the technical field of pet carriers, and more specifically to a foldable pet carrier.

Background Art

[0002] As pet breeding becomes more popular, pet carriers have become essential tools for taking pets out, going to the vet, or for walks. The robustness, operability, and storage ability of their structures greatly affect the user experience.

[0003] Many of the currently commercially available foldable pet carriers adopt a general-purpose folding frame and a split-door structure, making the assembly work complicated. Also, when placing the pet in the car, the owner has to lift it and store it in the car, which requires a lot of effort for medium and large-sized pets or pets with mobility problems, making it difficult to handle. In addition, the conventional folding structure results in a large volume after folding and cannot stand on its own, making storage and transportation troublesome and difficult to store in a narrow space.

[0004] In view of the above problems, the present invention proposes a new foldable pet carrier.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The object of the present invention is to provide a foldable pet carrier to solve the problems of existing pet carriers mentioned in the background art, namely, the labor required for the owner to lift and place the pet, the looseness of the door part and its tendency to vibrate, and the inconvenience of storage after folding.

Embodiments for Carrying out the Invention

[0021] Hereinafter, while referring to the drawings related to the embodiments of the present invention, the technical configuration in the embodiments will be clearly and comprehensively described. Note that the described embodiments are only a part of the present invention, not all embodiments. All embodiments obtained by those skilled in the art without creative efforts based on the embodiments of the present invention are included in the protection scope of the present invention.

[0022] Embodiment This embodiment aims to improve the problems such as door rattling, poor usability, and excessive volume after folding in a conventional pet car.

[0023] Referring to Figures 1 to 5, a foldable pet car is provided, comprising a base frame 1, to which a main frame 9 is hinged, and to which a door frame 10 is hinged. A door plate 11 is fixed to the door frame 10, a sleeve rod 12 is fitted and fixed to the door frame 10, and a fastener 13 is rotatably attached to the sleeve rod 12. A support base 14 is fitted and fixed to the door frame 10, a storage cavity 15 is provided in the support base 14, and the door frame 10 can be fitted into the storage cavity 15. A groove 16 is formed inside the support base 14, a spring 17 is fixed in the groove 16, a button 18 is fixed to the end of the spring 17, and the button 18 abuts against the door frame 10. A pair of first body rods 19 are symmetrically hinged to the base frame 1, and a handle frame 20 is hinged to the first body rods 19.

[0024] Referring to Figure 2, the first link rod 21 is hinged to the first body rod 19, the second link rod 22 is hinged to the end of the first link rod 21, the second body rod 23 is hinged to the end of the second link rod 22, and the second body rod 23 is hinged to the handle frame 20. The third body rod 24 is hinged to the handle frame 20, the fourth body rod 25 is hinged to the third body rod 24, and the fourth body rod 25 is hinged to the second body rod 23.

[0025] Referring to Figure 3, two wheel saddles 2 are attached to the base frame 1, and through holes 201 are drilled in both wheel saddles 2 and the base frame 1. Bolts 6 are inserted through the through holes 201, and nuts 7 are screwed onto the outer circumference of the bolts 6. Rear wheels 8 are symmetrically assembled to the base frame 1, the through holes 201 of the wheel saddles 2 and the base frame 1 are aligned, and the bolts 6 fit the dimensions of the through holes 201. A connecting base 3 is fixed to the wheel saddles 2, a connecting frame 4 is fixed to the lower part of the connecting base 3, and the front wheels 5 are rotatably mounted inside the connecting frame 4.

[0026] The assembly procedure in this embodiment is as follows: First, the assembly work is carried out. Position the wheel base 2 according to the mounting points on both sides of the base frame 1, and align the through holes 201 of the wheel base 2 and the base frame 1. Insert the bolt 6 through the aligned through holes 201, screw the nut 7 onto the outer circumference of the bolt 6 and tighten it to complete the fixed assembly of the wheel base 2 and the base frame 1. Next, rotatably assemble the front wheel 5 into the connecting frame 4, and attach the rear wheel 8 to both sides of the base frame 1 to complete the assembly of the entire wheel unit.

[0027] Next, the pet car is unfolded. When the handle frame 20 is pulled upward, the first body rod 19 rotates upward using the hinge of the base frame 1 as a pivot point. In conjunction with this, the first link rod 21, the second link rod 22, the second body rod 23, the third body rod 24, and the fourth body rod 25 rotate and unfold in sequence, and the main frame 9 and the base frame 1 support each other, forming a stable frame-like support structure, and the unfolding of the body frame is completed. As a side note, only the body frame portion is shown in the drawing to make the internal structure easier to understand. In the actual product, a cloth cover is attached to the outside of the frame, but since the shape and attachment method of the cloth cover are known technology, a detailed description is omitted here.

[0028] The usage procedure is as follows: The latch 13 attached to the sleeve rod 12 is rotated to release the restraint on the door frame 10 by the latch 13. Then, the door frame 10 is rotated downward using the hinge axis of the main frame 9 and the door frame 10 as a pivot point, inverting the door frame 10 to an oblique position. This causes the entire door frame 10 to form an acute angle with the ground, creating a stable climbing platform structure, allowing the pet to smoothly enter the vehicle by moving along the surface of the inverted door frame 10. After the pet enters the vehicle, the door frame 10 is rotated upward to return to the vertical closed position. At this time, the back surface of the door frame 10 comes into contact with the button 18 on the support base 14, pressing the button 18 and compressing the spring 17 in the groove 16. The compressed spring 17 constantly applies a push-back force, firmly suppressing shaking and rattling between the door frame 10 and the main frame 9 when pushing the pet cart. Finally, rotate the latch 13 in the opposite direction to lock the door frame 10 and the main frame 9 in place, completing the closing of the door.

[0029] After use, it is folded and stored. When the handle frame 20 is pushed downward, the first body rod 19 rotates in the opposite direction around the hinge of the base frame 1 as a pivot point. As a result, the first link rod 21, the second link rod 22, the second body rod 23, the third body rod 24, and the fourth body rod 25 fold in the opposite direction in conjunction, and the main frame 9 folds toward the base frame 1 along with the entire body. The door frame 10 converges inward together with the main frame 9 and folds in conjunction with the body. When folding is complete, the door frame 10 is tightly pressed against the outside of the main frame 9, and the entire assembly becomes compact with all components overlapping without gaps, significantly reducing the storage volume and making it suitable for everyday storage and transport.

[0030] In this specification, relative terms such as "first" and "second" are used simply to distinguish one component or operation from another, and do not imply or suggest that there is an actual sequence or correlation between these components or operations. Furthermore, "equipped with," "includes," and their derived terms mean non-exclusive inclusion. Thus, a process, method, article, or apparatus having multiple components includes not only the components described, but also other elements not explicitly described, or elements inherent to the process, method, article, or apparatus.

[0031] The above description is merely a preferred embodiment of the present invention. Those with ordinary skill in the art may make numerous improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications shall also fall within the scope of protection of the present invention.
