Description

Technical Field

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

[0002] In people's daily lives, canes play an indispensable role as an important walking aid. They are widely used by people with leg injuries or leg diseases who have difficulty moving, as well as the elderly who are frail and have reduced walking ability. They provide strong support for these people's daily travel, help them maintain their balance, reduce the risk of falls and injuries during walking, and greatly improve their safety and independence. However, most walking sticks currently on the market adopt a one-piece structure design. While this one-piece structure provides stable support during use, it exposes many obvious technical problems in the storage and packaging / transportation stages, causing considerable inconvenience to users and related businesses, and requires further improvement. From a user's storage perspective, because one-piece canes cannot be disassembled, their overall length remains fixed. When users don't need to use the cane indoors, they need to find a dedicated storage space. For example, in a small home environment, the excessive length of a one-piece cane makes it difficult to find a suitable corner for storage. Randomly placing it not only takes up a lot of indoor space but may also affect the tidiness and aesthetics of the indoor environment, and even pose a tripping hazard. For users who need to carry canes when going out, the one-piece cane is also inconvenient to carry when taking public transportation (such as buses and subways) or driving. Whether placed next to the seat or in the trunk, it takes up a lot of space, causing considerable inconvenience. From the perspective of packaging and transportation for merchants, the relatively long overall length of one-piece canes places higher demands on packaging materials and transportation methods. To ensure the canes are not damaged during transportation, merchants need to customize packaging materials with a length matching the canes, which undoubtedly increases packaging costs. Furthermore, in the express delivery process, the excessive length of the canes makes them unsuitable for transport as standard small items, often requiring higher shipping fees as large items. 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 folding cane structure.

[0004] A folding cane structure designed for this purpose includes a handle and a folding assembly, the folding assembly including at least two folding tubes arranged sequentially in the vertical direction, a connecting element disposed between two adjacent folding tubes, and an elastic connecting rope. The uppermost folding tube is connected to the handle; the lowermost folding tube is used to contact the ground to form support. The connecting element includes a first pair of insertion parts, a limiting part, and a second pair of insertion parts connected in sequence; both ends of the folded tube are provided with insertion spaces; When the connecting element is connected to two adjacent folded tubes, the first pair of insertion parts are interference-fitted into the insertion space of one of the folded tubes, the second pair of insertion parts are interference-fitted into the insertion space of the other folded tube, and the limiting part is fitted and limited to the opposite wall surfaces of the two folded tubes. The elastic connecting rope is sequentially threaded inside all the folded tubes; the upper end of the elastic connecting rope is fixedly connected to the uppermost folded tube, and the lower end is fixedly connected to the lowermost folded tube.

[0005] Preferably, the handle is provided with a downwardly extending extension tube, and the uppermost folding tube is fixedly connected to the extension tube.

[0006] Preferably, the extension tube is hollow inside and open at the lower end; the uppermost folding tube is at least partially inserted into the extension tube. The extension tube has multiple positioning pin holes arranged in a vertical direction; the uppermost folding tube has a mounting hole that communicates with any one of the positioning pin holes; a locking pin that can be inserted into any one of the positioning pin holes is movably disposed in the mounting hole; the locking pin is connected to the uppermost folding tube with an elastic element; the elastic element is used to push the locking pin into the positioning pin hole.

[0007] Preferably, the elastic element is a sheet or a spring.

[0008] Preferably, the lower end of the bottommost folded tube is fixedly connected with a rubber pad.

[0009] Preferably, the handle or the extension tube is connected to a hanging cord.

[0010] Preferably, the folded tube is made of carbon fiber material.

[0011] Compared with the prior art, this utility model has many significant advantages, as follows: Firstly, it achieves a breakthrough in storage and portability. This structure, utilizing a folding assembly consisting of at least two folding tubes and connecting elements, overcomes the limitation of traditional one-piece canes that cannot be disassembled. When the cane is not in use, the multiple folding tubes can be disassembled by separating the connecting elements and the folding tubes through an interference fit, significantly reducing the overall length and space occupied. For home storage, even in small living environments, the disassembled folding tubes can be easily stored in drawers, cabinet corners, etc., avoiding the problems of traditional canes being placed haphazardly, taking up space, affecting indoor tidiness, and creating tripping hazards. For travel scenarios, users can conveniently place the disassembled folding tubes into backpacks or handbags. Whether taking public transportation such as buses or subways, or driving and placing them in the vehicle's storage compartment, they do not take up much space, greatly improving portability and meeting diverse travel needs. Secondly, it significantly reduces packaging and transportation costs for merchants. Since the folding cane can be disassembled into multiple short folding tubes, there's no need to customize extra-long packaging materials to match the length of traditional one-piece canes during the factory packaging stage. Standard-sized packaging is sufficient to hold all the folding tubes, greatly reducing the customization and procurement costs of packaging materials. In the express delivery stage, the disassembled folding tubes meet the standard shipping specifications for small items, eliminating the need to pay high shipping fees as for large items. Furthermore, during bulk shipments, the transport vehicle can accommodate more folding tubes (compared to traditional one-piece canes, more disassembled products can be loaded within the same transport space), effectively improving the space utilization of the transport vehicle, reducing the unit product transportation cost, alleviating the economic pressure on merchants, and enhancing the product's market competitiveness.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] See Figures 1-3 A folding cane structure includes a handle 10 and a folding assembly 20. The folding assembly 20 includes at least two folding tubes 210 arranged sequentially in the vertical direction, a connecting element 200 disposed between two adjacent folding tubes 210, and an elastic connecting rope 220. The uppermost folding tube 210 is connected to the handle 10; the lowermost folding tube 210 is used to contact the ground to form support. The connecting element 200 includes a first pair of insertion parts 201, a limiting part 203, and a second pair of insertion parts 202 connected in sequence; both ends of the folded tube 210 are provided with insertion spaces; When the connecting element 200 is connected to two adjacent folded tubes 210, the first insertion part 201 is interference-fitted into the insertion space of one of the folded tubes 210, the second insertion part 202 is interference-fitted into the insertion space of the other folded tube 210, and the limiting part 203 is fitted and limited by the opposing wall surfaces of the two folded tubes 210. The elastic connecting rope 220 is sequentially threaded inside all the folded tubes 210; the upper end of the elastic connecting rope 220 is fixedly connected to the uppermost folded tube 210, and its lower end is fixedly connected to the lowermost folded tube 210.

[0015] The working principle of this folding cane structure revolves around two core scenarios: "assembly support" and "disassembly and storage." Through the coordinated operation of various components, it achieves convenient use and efficient storage, as detailed below: I. Assembly Support Principle When using a cane to assist walking, first use the traction and positioning effect of the elastic connecting rope to quickly find the corresponding connection position of each folded tube. Since the elastic connecting rope is threaded through all the folded tubes in sequence, and its two ends are fixed to the top and bottom folded tubes respectively, it can naturally pull the scattered folded tubes into a state of sequential arrangement in the vertical direction, avoiding component misalignment and simplifying the assembly and positioning steps. The folded tubes and connecting elements are then assembled: the first pair of inserts of the connecting element is aligned with the interlocking space of one of the folded tubes, and the second pair of inserts is aligned with the interlocking space of the adjacent folded tube. The two are then connected and fixed by an interference fit. The interference fit structure ensures that the connecting element and the folded tube form a tight and fixed relationship, preventing loosening during use. At the same time, the limiting part of the connecting element will precisely fit against the opposing walls of the two folded tubes, further limiting the radial displacement of the folded tubes and preventing the tubes from shifting or shaking under force. After all adjacent folding tubes are assembled through connecting elements, the entire folding assembly forms a rigid support structure extending in the vertical direction: the uppermost folding tube is firmly connected to the handle, providing a gripping fulcrum for the user's hand; the lowermost folding tube is in direct contact with the ground, and the overall rigid structure evenly transmits the pressure of the user's body to the ground, forming a stable support force to meet the user's needs for assisted walking.

[0016] II. Principles of Disassembly and Storage When the cane is no longer needed and needs to be stored or carried, the interference fit between the connecting element and the folding tube can be released by applying external force; by pulling two adjacent folding tubes in opposite directions, the first pair of plugs and the second pair of plugs of the connecting element can be disengaged from their corresponding plug spaces, thus enabling the disassembly of a single folding tube. During the disassembly process, the elastic connecting rope plays a crucial role: its two ends are fixed to the top and bottom folded tubes, and it passes through all the middle folded tubes. Therefore, even if the folded tubes are separated, they will be connected together by the elastic connecting rope, preventing the loss of individual parts. At the same time, the elasticity of the elastic connecting rope allows the folded tubes to move flexibly within a certain range, making it convenient for users to organize the multiple short folded tubes after disassembly, greatly reducing the overall space occupied, and making it easy to put into small spaces such as backpacks and drawers for storage or carrying. In summary, this folding cane, through the synergistic mechanism of "elastic connecting rope traction positioning + interference fit of connecting elements," not only ensures the stability of the support after assembly but also achieves the convenience of storage after disassembly, fully taking into account both functionality and practical needs. See Figures 1 to 3 The handle 10 is provided with an extension tube 110 extending downward, and the uppermost folding tube 210 is fixedly connected to the extension tube 110.

[0017] See Figures 1 to 3 The extension tube 110 is hollow inside and open at the lower end; the uppermost folded tube 210 is at least partially inserted into the extension tube 110; the extension tube 110 has a plurality of positioning pin holes 510 arranged in the vertical direction; the uppermost folded tube 210 has a mounting hole 520 that communicates with any one of the positioning pin holes 510; a locking pin 530 that can be inserted into any one of the positioning pin holes 510 is movably disposed in the mounting hole 520; the locking pin 530 is connected to the uppermost folded tube 210 by an elastic element 540; the elastic element 540 is used to push the locking pin 530 into the positioning pin hole 510. The extension tube is hollow and open at the bottom, allowing the uppermost folding tube to be partially inserted and moved relative to it. Combined with multiple positioning pin holes in the extension tube, mounting holes in the folding tube, a locking pin, and a spring element, the insertion length of both canes can be adjusted by moving the folding tube. The spring element pushes the locking pin into the corresponding positioning pin hole, enabling quick and flexible height adjustment to suit users of different heights. When it is necessary to disassemble the cane or adjust the height, simply press the locking pin to disengage it from the positioning pin hole.

[0018] Specifically, the elastic element 540 is a sheet or a spring.

[0019] See Figure 2 and Figure 3A connecting hook 230 is connected inside the uppermost folded tube 210, and the upper end of the elastic connecting rope 220 is connected to the connecting hook 230. A limiting member 240 is installed inside the lowermost folded tube 210, and a mating member 250 is provided inside the folded tube 210 below the limiting member 240. The mating member 250 can fit and limit the movement of the lower surface of the limiting member 240; the lower end of the elastic connecting rope 220 passes downward through the limiting member 240 and is fixedly connected to the mating member 250.

[0020] In this utility model, the lower end of the folded tube 210 located at the bottom is fixedly connected with a rubber pad 30.

[0021] In this utility model, the handle 10 or the extension tube 110 is connected to a hanging rope 120.

[0022] In this invention, the folded tube 210 is made of carbon fiber material.
