Description

Technical Field

[0001] This utility model relates to the field of cane technology, and in particular to a carbon fiber cane stool. Background Technology

[0002] As a portable device that combines walking assistance and temporary rest, the cane stool is widely used by the elderly, people with mobility impairments, and in outdoor travel scenarios. Its core value lies in achieving "dual use" through structural integration, meeting the user's dual needs when moving or resting. Existing cane stools generally consist of a first tube, a second tube, a seat, and a handle assembly. The first and second tubes, as core support components, are connected by a rotating structure to achieve relative rotation, thus switching between folded and unfolded states. When unfolded, the first and second tubes open at a certain angle, forming a stable support base, and the seat unfolds for the user to sit on. When folded, they come together to reduce space occupation for easy storage. However, the existing support structure design of cane stools has significant flaws, hindering further improvements in portability. Specifically, in existing technologies, the first and second tubes are designed as support components that directly contact the ground. To ensure stability and support height (adapting to the walking and sitting postures of adults), this direct-contact design necessitates sufficient length for the first and second tubes to meet support strength and user comfort requirements. However, this design results in excessively long tubes for the first and second tubes, leading to a larger overall volume that is difficult to store in containers and requires carrying by hand, causing inconvenience for users. Furthermore, the longer tube length increases storage space requirements, making it unsuitable for storage in limited spaces such as homes and cars. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a carbon fiber cane stool that can be reduced in size and is easy to store.

[0004] A carbon fiber cane stool designed for this purpose includes a first tube, a second tube, a seat plate, and a handle assembly; the second tube has two sections and is located on the first tube; the second tube is rotatably connected to the first tube. The rear side of the seat plate is rotatably connected to the first pipe fitting; The upper end of the second pipe extends upward to the lower front of the seat plate and is rotatably connected to the seat plate; The lower end of the first pipe fitting is detachably connected to a downwardly extending first support pipe; the first pipe fitting and the first support pipe are connected by a first elastic rope; The lower end of the second pipe fitting is detachably connected to a downwardly extending second support pipe; the second pipe fitting and the second support pipe are connected by a second elastic rope; The upper end of the first tube extends upward and is connected to the handle assembly.

[0006] Preferably, the lower end of the first pipe fitting is connected to a second plug fitting; The second connector includes a third connector portion, a second limiting portion, and a fourth connector portion connected in sequence; The third insertion part is interference-fitted with the first pipe fitting; The fourth connector is interference-fitted with the first support tube. The second limiting part is in contact with the lower end face of the first pipe fitting and the upper end face of the first support pipe.

[0007] Preferably, the grip assembly includes a third tube and a grip connected to the third tube; The third pipe fitting is detachably connected to the first pipe fitting; The third pipe fitting is connected to the first pipe fitting by a third elastic rope.

[0008] Preferably, the lower end of the third pipe fitting is connected to a third plug fitting; The third connector includes a fifth connector portion, a third limiting portion, and a sixth connector portion connected in sequence; The fifth insertion part is interference-fitted with the third pipe fitting; The sixth connector is interference-fitted with the first pipe fitting. The third limiting part is in contact with the lower end face of the third pipe and the upper end face of the first pipe.

[0009] Preferably, the seat plate is provided with a C-shaped clamp that engages with the first pipe fitting.

[0010] Preferably, the lower end of the first support tube is connected to the lower end of the second support tube with a rubber pad.

[0011] Preferably, the first fitting, the second fitting, the first support tube, and the second support tube are made of carbon fiber.

[0012] Compared with the prior art, this utility model has achieved significant optimization in terms of storage portability and assembly convenience, and the specific beneficial effects are as follows: Significantly reducing the folded length and improving portability: Addressing the issue of existing cane stools remaining too long after folding due to the direct contact of the tubes with the ground, this innovative solution features a first support tube detachably connected to the lower end of the first tube and a second support tube detachably connected to the lower end of the second tube. When the cane stool is not in use and needs to be stored, the user can directly detach the first support tube from the first tube and the second support tube from the second tube. At this point, the first and second tubes retain only their basic lengths, resulting in a significantly shorter overall length compared to existing cane stools after folding. The shortened cane stool is easier to fit into backpacks, tote bags, and other storage containers, eliminating the need to hold it separately. This effectively solves the pain points of existing products, such as large storage volume and inconvenience in carrying, and is especially suitable for the daily travel and outdoor use needs of elderly users and those with mobility impairments. Elastic ropes prevent separation and ensure quick reassembly. A first elastic rope connects the first fitting to the first support tube, and a second elastic rope connects the second fitting to the second support tube. This design prevents complete separation of the first support tube from the first fitting and vice versa after the support tubes are disassembled. On one hand, it prevents the loss of the support tubes after disassembly, reducing the risk of lost parts during use. On the other hand, when the user needs to use the cane stool again, the elastic ropes quickly locate the corresponding fitting and support tube, eliminating the need to find matching parts. Assembly is completed simply by reassembling the support tube back into the corresponding fitting, simplifying the assembly process and improving ease of use, especially for elderly users with limited dexterity.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] See Figures 1-7 A carbon fiber cane stool includes a first tube 10, a second tube 20, a seat 30, and a handle assembly 40. Two second tubes 20 are provided and located at the first tube 10. The second tube 20 is rotatably connected to the first tube 10. The rear side of the seat 30 is rotatably connected to the first tube 10. The upper end of the second tube 20 extends upward to the lower front of the seat 30 and is rotatably connected to the seat 30. The lower end of the first tube 10 is detachably connected to a downwardly extending first support tube 110. The first tube 10 and the first support tube 110 are connected to a first elastic cord 620. The lower end of the second tube 20 is detachably connected to a downwardly extending second support tube 210. The second tube 20 and the second support tube 210 are connected to a second elastic cord 220. The upper end of the first tube 10 extends upward and is connected to the handle assembly 40.

[0016] This carbon fiber cane stool, through the rotating connection and detachable design of its components, allows for switching between functions such as "assisted walking - temporary sitting and rest - portable storage." The specific operating principle is as follows: 1. Unfolding and Using: Switching from storage mode to walking / sitting mode Support tube assembly: In the stored state, the first support tube 110 and the second support tube 210 have been removed from the corresponding fittings. Before use, the support tubes must be assembled: With the help of the first elastic rope 620 for traction and positioning, align the first support tube 110 with the connection structure (such as interference fit, snap, thread, etc.) at the lower end of the first fitting 10 and fix it, so that the first support tube 110 extends downward to form the main support leg of the cane stool; similarly, with the second elastic rope 220 for positioning, assemble the two second support tubes 210 to the lower end of the corresponding second fittings 20 and fix them to form the auxiliary support legs on both sides. The overall structure unfolds; after assembly, the two second tubes 20 are pushed to rotate around their rotational connection point with the first tube 10. At the same time, the upper end of the second tube 20 will drive the seat plate 30 to flip upward around its rear rotation point with the first tube 10. When the second tube 20 rotates to a preset angle with the first tube 10, the seat plate 30 will unfold to a horizontal state with the support of the second tube 20. At this time, the entire cane stool forms a stable base with three-point support of "first support tube 110 + two second support tubes 210". The seat plate 30 can bear the user's weight for temporary rest. If only walking assistance is needed, it is not necessary to fully unfold the seat plate 30. Just adjust the second tube 20 to an appropriate angle, hold the handle assembly 40, and walking assistance can be achieved with the support of the first support tube 110 and the second support tube 210. Disassemble the support tubes; disconnect the fixed connections between the first support tube 110 and the first fitting 10, and between the second support tube 210 and the second fitting 20. At this time, the first elastic cord 620 will suspend the first support tube 110 from the lower end of the first fitting 10, and the second elastic cord 220 will suspend the second support tube 210 from the lower end of the corresponding second fitting 20 to prevent the support tubes from being lost. After disassembly, the first fitting 10 and the second fitting 20 retain only their basic length, and the overall volume is greatly reduced. They can be directly put into a backpack or handbag for carrying, meeting the user's portable travel needs.

[0017] See Figure 4 The lower end of the second pipe fitting 20 is connected to a first plug-in component 230; the first plug-in component 230 includes a first plug-in portion 231, a first limiting portion 232 and a second plug-in portion 233 connected in sequence; the first plug-in portion 231 is interference-fitted with the second pipe fitting 20; the second plug-in portion 233 is interference-fitted with the second support pipe 210; the first limiting portion 232 is in contact with the lower end face of the second pipe fitting 20 and the upper end face of the second support pipe 210. The first connector 230 is the core connecting component between the second pipe 20 and the second support pipe 210. Through the sequential connection of the first connector 231, the first limiting part 232, and the second connector 233, it achieves a detachable interference fit between the two components. The first connector 231 is interference-fitted with the second pipe 20, and the second connector 233 is interference-fitted with the second support pipe 210, allowing for quick assembly without additional tools. This ensures a stable connection and accommodates the need to disassemble the support pipe during storage. Furthermore, the first limiting part 232 simultaneously abuts against the lower end face of the second pipe 20 and the upper end face of the second support pipe 210, precisely limiting the insertion depth and preventing the support pipe from tilting due to excessive or shallow insertion, thus ensuring overall support stability. Additionally, if further strengthening of the connection is required (e.g., for long-term, high-frequency use), the first connector 231 and the second pipe 20 can be glued together according to connection requirements, enhancing connection reliability while retaining the detachable characteristic and adapting to the usage intensity needs of different users.

[0018] See Figure 7 The lower end of the first pipe fitting 10 is connected to a second plug-in 610; the second plug-in 610 includes a third plug-in portion 611, a second limiting portion 612, and a fourth plug-in portion 613 connected in sequence; the third plug-in portion 611 is interference-fitted with the first pipe fitting 10; the fourth plug-in portion 613 is interference-fitted with the first support pipe 110; the second limiting portion 612 is in contact with the lower end face of the first pipe fitting 10 and the upper end face of the first support pipe 110. The second connector 610 is a key component for achieving a stable connection between the first tube 10 and the first support tube 110. Through the sequentially connected third connector 611, second limiting connector 612, and fourth connector 613, it plays a dual core role: On the one hand, with the interference fit between the third connector 611 and the first tube 10, and the interference fit between the fourth connector 613 and the first support tube 110, the two can be quickly assembled and disassembled without the need for additional tools. This ensures the stability of the connection during daily use and meets the need to disassemble the first support tube 110 to shorten its length when storing it. On the other hand, the second limiting connector 612 can simultaneously fit tightly against the lower end face of the first tube 10 and the upper end face of the first support tube 110, which can precisely limit the insertion depth of the two and effectively prevent the first support tube 110 from tilting due to excessive or shallow insertion, thus ensuring the overall support stability of the cane stool. In addition, for scenarios requiring higher connection strength, such as long-term high-frequency use, the third plug part 611 can be glued and fixed to the first tube 10 according to the actual connection needs. This further enhances the connection reliability while retaining the detachable feature, and adapts to the usage strength needs of different users.

[0019] See Figure 1 and Figure 5 The handle assembly 40 includes a third tube 410 and a handle 420 connected to the third tube 410; the third tube 410 is detachably connected to the first tube 10; and a third elastic cord 520 is connected to the third tube 410 and the first tube 10. The detachable connection between the third tube 410 and the first tube 10 allows users to easily separate the two components according to their needs or storage requirements, further reducing the overall size of the cane stool and improving portability. The third elastic cord 520 also prevents the third tube 410 from completely separating from the first tube 10 after disassembly, preventing component loss and facilitating quick reassembly. The handle 420 provides comfortable support for the user's grip, ensuring operational stability during assisted walking.

[0020] See Figure 6The lower end of the third pipe fitting 410 is connected to a third plug-in component 510; the third plug-in component 510 includes a fifth plug-in portion 511, a third limiting portion 512, and a sixth plug-in portion 513 connected in sequence; the fifth plug-in portion 511 is interference-fitted with the third pipe fitting 410; the sixth plug-in portion 513 is interference-fitted with the first pipe fitting 10; the third limiting portion 512 is in contact with the lower end face of the third pipe fitting 410 and the upper end face of the first pipe fitting 10. The third connector 510 is a key component for achieving a stable and detachable connection between the third tube 410 and the first tube 10. Its specific functions are as follows: Among the fifth connector 511, the third limiting part 512, and the sixth connector 513 connected in sequence, the fifth connector 511 is interference-fitted with the third tube 410, and the sixth connector 513 is interference-fitted with the first tube 10. The two can be quickly assembled without tools, ensuring the stability of the connection. At the same time, the third limiting part 512 fits against the lower end face of the third tube 410 and the upper end face of the first tube 10, which can accurately limit the insertion depth of the two, avoid the grip assembly 40 from tilting due to over-insertion, ensure the stability when the user holds the grip, and further optimize the assembly and use effect of the grip assembly.

[0021] In this invention, the seat plate 30 is provided with a C-shaped locking member 310 that engages with the first pipe fitting 10. The core function of this structure is to form a locking engagement with the first pipe fitting 10 when the seat plate 30 is folded: when the seat plate 30 is rotated around its rotational connection point with the first pipe fitting 10 to a folded state that fits the pipe fitting, the C-shaped locking member 310 can quickly lock the first pipe fitting 10, preventing the folded seat plate 30 from shaking or unfolding at will.

[0022] In this invention, the lower end of the first support tube 110 and the lower end of the second support tube 210 are connected by a rubber pad.

[0023] In this utility model, the first pipe fitting 10, the second pipe fitting 20, the first support pipe 110, and the second support pipe 210 are made of carbon fiber.
