Description

Technical Field

[0001] This application relates to the field of walking aid technology, specifically a small-sized portable walking aid. Background Technology

[0002] Walking aids enable elderly people, patients, and others with mobility issues or even those who have lost the ability to walk to take care of themselves and go for walks like able-bodied people. Currently, some walking aids on the market can be quickly folded and are small in size, but they do not have a seat function when unfolded. Others with seats are relatively large when folded, making them inconvenient to put next to the car seat and only able to be put in the trunk. This makes it inconvenient to carry when taking the elderly out for a walk. In addition, while quick-folding small walking aids without seats are small in size when folded, people or the elderly who are tired still have to find a place to sit temporarily, which does not provide this convenient function.

[0003] Furthermore, when using existing walking aids for uphill assistance, the device is tilted, causing the user's center of gravity to shift backward, resulting in instability.

[0004] Therefore, it is necessary to provide a small, portable walking aid to solve the above problems. Utility Model Content

The seat structure 2 includes two casters 103 that are fixedly installed on the folding brackets 101. A support base 201 is installed between the two mounting clips 203. A protective shell 202 is provided between the two support bases 201. A support rod 204 is installed at the bottom of each of the two support bases 201. The opposing surfaces of the two support rods 204 are provided with mutually meshing mounting gears 205. The two mounting gears 205 are located inside the protective shell 202.

[0027] The folding bracket 101 has a pneumatic lifting structure 3 on each of the two poles furthest from the person. The pneumatic lifting structure 3 includes a pneumatic housing 301. Four support columns 305 are installed on the top of the pneumatic housing 301. A connecting plate 306 is installed on the top of the support columns 305. An extension rod 302 is slidably installed on the bottom of the pneumatic housing 301. A limiting shell 304 is fixedly connected inside the pneumatic housing 301. A sealing disc 303 is installed on the top of the extension rod 302 inside the pneumatic housing 301. An air guide pipe 307 is installed on the top of the pneumatic housing 301. The other end of the air guide pipe 307 is connected to the bottom of one side of the pneumatic housing 301. A mounting block 310 is installed on one side of the pneumatic housing 301. A pneumatic turntable 308 is rotatably installed on one side of the mounting block 310. The other end of the pneumatic turntable 308 extends through the mounting block 310 and one side of the air guide pipe 307 into the air guide pipe 307 and is connected to a ball head 309.

[0028] The air pressure housing 301 is filled with compressed gas, and one end of the extension rod 302 and one end of the connecting plate 306 are installed in the middle section of the front of the folding bracket 101.

[0029] The handbrake 107 controls the operation of the two brake assemblies 104 via a connecting cable, the handle 102 can be folded according to the folding bracket 101, and the locking bolt 106 can lock and release the telescopic rod 105.

[0030] The ball head 309 has an exhaust port in the middle, and the sealing disc 303 can divide the entire compartment inside its air pressure shell 301 into two.

[0031] The outer wall of the pneumatic turntable 308 is provided with several anti-slip grooves.

[0032] Working principle:

[0033] Before using the device, first check all its components to ensure that they work properly and that the device can operate normally.

[0034] When using the device, the user first opens the device and adjusts it according to their own height. First, the user rotates the two locking bolts 106 to loosen the two telescopic rods 105. The user then lifts the two handles 102 to raise the telescopic rods 105. When the rods reach the appropriate position, the user locks the two telescopic rods 105 with the two locking bolts 106 to make the height suitable.

[0035] When the device is opened, the two support seats 201 are opened by two mounting gears 205 hidden in the protective housing 202, and the two support seats 201 form a cushion.

[0036] When the user is going uphill, the height of the air pressure lifting structure 3 can be adjusted according to the slope so that the device remains in a horizontal state or is lowered further in front. By rotating the air pressure turntable 308, the air pressure turntable 308 drives the ball head 309 to rotate. When the ball head 309 rotates, it connects to the air guide pipe 307. The user presses the device forward, causing the extension rod 302 to move the sealing plate 303 inside the air pressure housing 301. The high-pressure gas above the sealing plate 303 is squeezed through the air guide pipe 307 to the bottom of the sealing plate 303. The extension rod 302 retracts into the interior of the air pressure housing 301, realizing the downward descent to adapt to the slope.

[0037] By incorporating the main body structure 1, the device can be quickly folded and unfolded. Furthermore, by incorporating the telescopic rod 105, the device can be adjusted to accommodate users of different heights, thereby enhancing its practicality.

[0038] The seat cushion structure 2 helps users sit down, providing them with a convenient resting environment.

[0039] By incorporating a pneumatic lifting structure 3, the device can be adjusted to maintain a horizontal position when the user is going uphill, preventing the user from shifting their center of gravity backward.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
