Description

Technical Field

[0001] This utility model relates to the field of walking trolley technology, specifically to a multi-functional flip-top trolley. Background Technology

[0002] A walking cart is a mobile tool that combines walking assistance and cargo carrying functions, primarily serving people with mobility impairments.

[0003] Most walkers, while assisting users in walking and carrying items, have limited space on the stool. Furthermore, if a user gets tired and wants to sit down, they must remove the items from the stool, making the process somewhat cumbersome.

[0004] Therefore, a multi-functional flip-top trolley is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a multifunctional flip-top trolley to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A multi-functional flip-top trolley includes a folding frame, with casters and omnidirectional wheels at the bottom of the frame. A footrest is hinged to the frame, along with a backrest and a stool. A fixing block and a U-shaped buckle are attached to the surface of the stool and engage with the frame. A storage bag is located below the stool. A mounting base with an armrest hinged to it is also provided. A brake assembly is mounted on the frame.

[0008] Furthermore, the number of the fixing blocks and U-shaped buckles is set to two, and they are symmetrically distributed.

[0009] Furthermore, the connection between the folding frame and the storage bag is a fixed connection, and the connection is secured by cable ties.

[0010] Furthermore, the folding frame is made of aluminum alloy profiles, and the wall thickness of the aluminum profiles is 2.3mm and 2.0mm.

[0011] Furthermore, the connection between the folding frame and the mounting base is a fixed connection, and it is fixed by bolt connection.

[0012] Furthermore, the backrest has a fabric layer on the backrest side and a mesh layer on the non-backrest side, with memory foam filling inside the fabric layer.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model, through the design of a folding frame, U-shaped buckles, and storage bags, allows for easy storage in a vehicle trunk or home by folding the frame. During normal use, the user can hold the folding frame and engage the brake assembly, allowing movement via the combination of the casters and swivel wheels. At higher speeds, the brake assembly can be used to slow down or stop the vehicle. To store items, an upward pulling force can be applied to the stool, disengaging the U-shaped buckles from the folding frame and flipping the stool over to reveal the storage bags. Items can then be placed inside. Inside the storage bag, the stool is flipped over so that the U-shaped buckle locks onto the folding frame, closing the stool. It can also be used to store items or for the user to sit on. The footrest and armrests provide comfort. The hinges between the folding frame and the footrest, and between the mounting base and the armrests, facilitate folding and reduce space. However, the footrest and armrests can only be flipped upwards, not downwards, due to the restriction below. This design allows for the opening and closing of the stool, with a storage bag underneath for convenient storage, expanding storage space. It is foldable, easy to store, simple to operate, and highly practical. Attached Figure Description

[0024] like Figs. 1-3 As shown, a multi-functional flip-top trolley includes a folding frame 1, with casters 2 and 3 at the bottom of the frame 1, a footrest 4 hinged to the frame 1, a backrest 5, and a stool 6 hinged to the frame 1. A fixing block 7 is mounted on the surface of the stool 6, and a U-shaped buckle 8 is attached to the surface of the fixing block 7 and engages with the frame 1. A storage bag 9 is located below the stool 6 on the frame 1. A mounting base 10 is mounted on the frame 1, with an armrest 11 hinged to the mounting base 10. A brake assembly 12 is also mounted on the frame 1. Figs. 1-3 As shown, specifically, the number of fixing blocks 7 and U-shaped buckles 8 is set to two, symmetrically distributed. The connection between the folding frame 1 and the storage bag 9 is a fixed connection, which is fixed by binding with cable ties. The material of the folding frame 1 is set to aluminum alloy profile, and the wall thickness of the aluminum profile is 2.3mm and 2.0mm. The connection between the folding frame 1 and the mounting base 10 is a fixed connection, which is fixed by bolt connection. The backrest 5 has a fabric layer on the back-facing side and a mesh layer on the non-back-facing side. The fabric layer has memory foam filling inside.

[0025] More specifically, by setting the number of fixing blocks 7 and U-shaped buckles 8, the stability of the stool board 6 in the closed state is improved. The folding frame 1 and the storage bag 9 are fixedly connected by cable ties, and the installation and fixation can be completed without tools. The fixation is highly stable and the maintenance cost is low. By setting the material and wall thickness of the folding frame 1, it is lightweight while being able to bear 100kg. The folding frame 1 is fixedly connected to the mounting base 10 by bolts, which facilitates its assembly and disassembly. The fabric side of the backrest 5 provides a soft touch to reduce skin friction and discomfort, while the mesh side enhances breathability. The fabric layer has memory foam filling inside, which can adapt to the spinal curve and reduce lumbar pressure. The mesh layer assists in load-bearing through elastic tension and avoids local pressure concentration.

[0026] In summary, the brake assembly 12 consists of brake shoes, springs, steel cables, friction pads, and brake drums. When the user squeezes the handle, the cable retracts, causing the brake shoes to open. Friction forces the moving wheels 2 to decelerate and brake. By folding the folding frame 1, it can be retracted to save space, making it easy to put into the trunk of a vehicle or at home. During normal use, the user can hold the folding frame 1 and contact it with the brake assembly 12. The moving wheels 2 and the casters 3 work together to move the vehicle. When pushing at a high speed, the brake assembly 12 can be used to decelerate or stop the vehicle. If it is necessary to store items, an upward pulling force can be applied to the stool 6 to disengage the U-shaped buckle 8 from the folding frame 1, allowing the stool 6 to flip over. The storage bag 9 will then be exposed, allowing items to be placed inside. The stool 6 can then be flipped over, causing the U-shaped buckle 8 to engage with the folding frame 1, closing the stool 6. This allows for storage of items or seating. The footrest 4 and armrest 11 provide comfort for the user. The hinges between the folding frame 1 and footrest 4, and between the mounting base 10 and armrest 11, facilitate folding and reduce space. However, the footrest 4 and armrest 11 can only be flipped upwards, not downwards, due to the restriction below. This design allows for the opening and closing of the stool 6, with the storage bag 9 underneath for convenient storage, expanding storage space. The stool is foldable, easy to store, simple to operate, and highly practical.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
