Detailed Implementation

[0020] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific embodiments of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solutions claimed in the present invention.

[0021] like Figure 1-7 As shown, this embodiment provides a portable walking aid, including a seat assembly 1, a first folding structure 2 and a frame assembly 3. The frame assemblies 3 on both sides are connected to the seat assembly 1 through the first folding structure 2, and the seat assembly 1 can be unfolded or folded. The frame assembly 3 includes an armrest assembly 31, a front leg assembly 32, a rear leg assembly 33, and a second folding structure 34. The two sides of the seat cushion assembly 1 are respectively connected to the armrest assembly 31 through the first folding structure 2. The front leg assembly 32 and the rear leg assembly 33 are rotatably connected to the armrest assembly 31 through the second folding structure 34, so that the armrest assembly 31 and / or the front leg assembly 32 can be folded or unfolded relative to the rear leg assembly 33.

[0022] The present invention proposes a portable walking aid that can be folded up, which is beneficial for merchants' warehousing and transportation, and is also convenient for users to store and carry when going out in a vehicle.

[0023] Furthermore, the first folding structure 2 includes an upper limit part 21, an upper hinge tube 22, a lower hinge tube 23, and a lower limit part 24. The upper limit parts 21 and the lower limit parts 24 on both sides are respectively fixed to the inner side of the armrest assembly 31 on both sides. The upper sides of the two upper hinge tubes 22 are respectively hinged to the two upper limit parts 21, and the lower sides of the two lower hinge tubes 23 are respectively hinged to the two lower limit parts 24. The middle parts of the two lower hinge tubes 23 are hinged by a screw, and the upper ends of the two lower hinge tubes 23 are respectively hinged to the upper hinge tubes 22 on the opposite side.

[0024] The upper limit part 21, upper hinge tube 22, lower hinge tube 23 and lower limit part 24 are designed to be simple and convenient. When opened, they can provide sufficient support for the whole structure, and when closed, they are also convenient.

[0025] Furthermore, a protective plug 4 is provided at the upper end of the lower hinged pipe 23. The protective plug 4 includes a protective plug body 41. The lower end of the protective plug body 41 can be interference-fitted with the pipe wall of the lower hinged pipe 23. An upper hinged pipe groove 221 is provided at the lower end of the upper hinged pipe 22. A reinforcing rib 42 extends from the upper end of the protective plug 4. When the protective plug body 41 is rotated into the upper hinged pipe groove 221, the reinforcing rib 42 abuts against the outer side of the pipe wall of the upper hinged pipe 22.

[0026] The design of the protective plug 4 is ingenious. In particular, the reinforcing rib 42, when the walking aid needs to be deployed, ensures that the lower hinge tube 23 and the upper hinge tube 22 are aligned, thus strengthening the support at the connection between them. This makes the connection between the lower hinge tube 23 and the upper hinge tube 22 on opposite sides more stable when the walking aid is deployed.

[0027] Preferably, the first folding structure 2 further includes a first reinforcing strip 25 and a second reinforcing strip 26. The outer sides of the first reinforcing strip 25 and the outer sides of the second reinforcing strip 26 are respectively hinged to the lower limiting portions 24 on both sides, and the inner sides of the first reinforcing strip 25 and the inner sides of the second reinforcing strip 26 are hinged by a screw.

[0028] The first reinforcing strip 25 and the second reinforcing strip 26 provide further support for vehicle stability.

[0029] Furthermore, a sliding buckle 5 is fitted onto the first reinforcing strip 25. A partition 51 is provided in the middle of the sliding buckle 5. A first reinforcing strip connecting hole 52 is provided on the front side of the partition 51 and inside the sliding buckle 5. The first reinforcing strip 25 is fitted into the first reinforcing strip connecting hole 52. A second reinforcing strip groove 53 is provided on the rear side of the partition 51. The end of the second reinforcing strip 26 can be limited in the second reinforcing strip groove 53. A spring groove 54 protrudes outward from the side wall of the sliding buckle 5 inside the first reinforcing strip connecting hole 52. A spring 6 is fixed on the first reinforcing strip 25, and the spring 6 can move within the spring groove 54. A handle 55 is also provided on the outside of the sliding buckle 5.

[0030] The sliding buckle 5, though small in size, is highly functional. When the first reinforcing bar 25 and the second reinforcing bar 26 are at the same horizontal position, the spring 6 pushes the sliding buckle 5 to the connection point of the first reinforcing bar 25 and the second reinforcing bar 26, thus reinforcing the connection. When the walking aid needs to be folded up, the user can easily unlock the first reinforcing bar 25 and the second reinforcing bar 26 by pressing the handle 55 and pushing the sliding buckle 5. The operation is simple, and the strengthened connection between the first reinforcing bar 25 and the second reinforcing bar 26 enhances the stability of the seat assembly 1.

[0031] Preferably, the handrail assembly 31 includes a handrail tube 311 and a handrail 312. The handrail 312 is detachably disposed on the upper end of the handrail tube 311. The upper limit part 21 and the lower limit part 24 are respectively fixed to the lower side and the middle part of the inner side of the handrail tube 311.

[0032] The design of the handrail tube 311 and handrail 312 allows users to adjust the height of the handrail 312 as needed.

[0033] Furthermore, the seat cushion assembly 1 includes a soft cushion 11, a seat cushion support tube 12, and a seat cushion connecting tube 13. The seat cushion support tube 12 is fixed to the rear side of the upper limit part 21 on both sides, and the seat cushion connecting tube 13 is hinged to the front side. The two sides of the soft cushion 11 can be respectively fastened to the seat cushion support tube 12 and the seat cushion connecting tube 13 on the same side.

[0034] The seat support tube 12 strengthens the connection of the soft cushion 11, ensuring that the soft cushion 11 remains horizontal when the walking aid is unfolded and placed on top. The seat connecting tube 13 is hinged to the upper limit part 21. Preferably, a reinforcing structure is provided at the hinge point to ensure that the seat connecting tube 13 remains stable with the upper limit part 21 when unfolded and does not rotate arbitrarily when folded. The seat connecting tube 13 is hinged to the upper limit part 21 so that it can be folded up when the user needs to fold the walking aid, preventing it from scratching others.

[0035] Furthermore, the second folding structure 34 includes a front foot connector 341, a rear foot connector 342, a handrail connector 343, and a support assembly 7. The front foot connector 341 is disposed on the upper end of the front foot assembly 32, the rear foot connector 342 is disposed on the upper end of the rear foot assembly 33, and the handrail connector 343 is disposed on the lower end of the handrail tube 311. The front foot connector 341, the rear foot connector 342, the handrail connector 343, and the support assembly 7 can be hinged together by bolts. A cover 344 is provided on the outside of the second closing structure 34.

[0036] The second folding structure 34 has a simple structure. Preferably, a groove is provided in the front foot connector 341 or the rear foot connector 342, so that the two can be connected to each other and then connected to the armrest connector 343. This not only strengthens the connection between the front foot connector 341 or the rear foot connector 342, but also makes the second folding structure 34 occupy less space overall.

[0037] Furthermore, the support component 7 includes a first support bar 71, a second support bar 72, and a third support bar 73. The front side of the first support bar 71 is hinged to the front foot component 32, the rear side of the second support bar 72 is hinged to the rear foot component 33, the first support bar 71 and the second support bar 72 are hinged together, and the upper end of the third support bar 73 is hinged to the handrail tube 311, and the lower end is hinged to the first support bar 71 or the second support bar 72.

[0038] The first support bar 71 and the second support bar 72 facilitate the unfolding or folding of the rear leg assembly 33 and the front leg assembly 32. When the rear leg assembly 33 and the front leg assembly 32 need to be unfolded, the first support bar 71 and the second support bar 72 provide support for both. In particular, the third support bar 73 strengthens the connection between the first support bar 71 and the second support bar 72 and the overall walking aid, making the support assembly 7 as a whole, as well as the rear leg assembly 33 and the front leg assembly 32, more stable.

[0039] Furthermore, casters 8 are installed at the lower ends of both the front foot assembly 32 and the rear foot assembly 33.

[0040] The casters 8 facilitate the movement of the walking aid. Preferably, the casters 8 on the rear foot assembly 33 are equipped with a braking structure, making the walking aid safer overall and easier for the user to park.

[0041] The above descriptions are merely some embodiments of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
