This makes everyday activities like bending over, walking, standing, and even standing up difficult. This increases the risk of falls, making mobility a major issue for the elderly. Crutches have become a popular solution for this problem. However, current crutches on the market primarily focus on preventing falls, while none address the problem of how to easily pick up the crutch without bending over. Furthermore, when elderly people use crutches on public transportation, they often have nowhere to place them, further increasing the risk of falls. Furthermore, existing crutches with assistive standing functions make them bulky, making them difficult to carry and store. Furthermore, while existing crutches offer height adjustment, these are primarily limited to selectable positions and cannot be customized to suit the user's height, resulting in a less than optimal user experience.

[0027] Furthermore, the transmission shaft 30 is stuck in the internal support rib 28 of the auxiliary crutch standing component 1 at the left end, and is connected to the transmission gear 1 31 at the right end. The transmission gear 1 31 is a 16-tooth gear with a pitch circle diameter of 6.4mm. The transmission shaft 2 35 passes through the internal auxiliary rib 34 of the auxiliary crutch standing component 2, and is connected to the transmission gear 2 33 at the left end and the transmission gear 3 36 at the right end. The transmission gear 2 33 is a 16-tooth gear with a pitch circle diameter of 6.4mm. The transmission gear 3 36 is a 16-tooth gear with a pitch circle diameter of 6.4mm.

[0028] When used on a bus, after the elderly sit down, they only need to open the magnetic buckle 7 connected to the end of the magnetic buckle ring 6 and hang it on the hollow part of the upper part of the bus seat back.

[0029] When the elderly stand up from a sitting position, Figure 1 The auxiliary armrest 9 in the folded state is unfolded around the bolt 8, and under the driving action of the movable rivet group 10 and the connecting shaft 12, the folding support frame 11 and the foldable support frame 2 13 are unfolded in the folded state. Figure 3 In the supporting state, the lower end of the foldable support frame 2 13 is clamped in the lower end of the folding bracket groove 15. The elderly only needs to hold the auxiliary armrest 9 with one hand and the crutch handle 2 with the other hand, and support the body with both hands at the same time, and can stand up with the support of the auxiliary armrest 9 and the crutch handle 2.

[0030] When the elderly need to adjust the height of the crutches according to their personal height, they only need to adjust the crutches Figure 1In this state, hold the anti-slip texture 18 on the outer upper part of the tightening buckle sleeve 19 with your hand, rotate it counterclockwise relative to the upper body 14 of the crutch until there is resistance, and then slide the tightening buckle sleeve 19 downward to separate the tightening buckle sleeve 19 and the tightening buckle tube 17 that are connected to each other under the action of the tightening buckle 20 and the tightening buckle groove 16. Figure 5 The lower part of the tightening clip 17 is clamped with the telescopic main body 21 of the crutch, so that the telescopic main body 21 of the crutch will not slide up and down relative to the tightening clip 17, thereby achieving the purpose of height adjustment.

[0031] When the crutch falls, the elderly do not need to bend over to help the elderly stand up. They can step on the flat cut part of the upper part of the auxiliary crutch standing component 24 and rotate the auxiliary crutch standing component 24 90 degrees relative to the ground with the central axis of the flip moving piece 29 at the right end of the auxiliary crutch standing component as the rotation axis. In this process, since the left end of the transmission shaft 30 is stuck in the internal support rib 28 of the auxiliary crutch standing component, the auxiliary crutch standing component 24 drives the transmission gear 1 31 connected to the right end of the transmission shaft 30 to rotate 90 degrees. Since the transmission gear 1 31 and the transmission gear 2 33 are engaged with each other, the transmission gear 2 33 rotates 90 degrees. Since the transmission gear 2 33 is connected to the left end of the transmission shaft 2 38, it drives the transmission shaft 2 The transmission gear three 36 connected to the right end of 38 rotates 90°. Since the transmission gear three 36 and the 18-tooth gear on the left end of the transmission gear four 39 are meshed with each other, and the gear ratio of the transmission gear three 36 and the 18-tooth gear on the left end of the transmission gear four 39 is 8:9, since the ratio of the number of teeth of the two gears is equal to the inverse ratio of the rotation speed of the two gears, and the rotation time of the two gears is the same, the rotation angle ratio of the two gears is the inverse ratio of the number of teeth. Therefore, at this time, the transmission gear four 39 rotates 80°. Since the anti-reverse ratchet 42 can only rotate counterclockwise relative to the 36-tooth ratchet on the right end of the transmission gear four 39, the anti-reverse ratchet 42 also rotates 80° under the drive of the 36-tooth ratchet on the right end of the transmission gear four 39, thereby driving the auxiliary crutch standing component 1 24 and the auxiliary crutch standing component 1 to rotate. The other crutches of the assisting crutch standing component 25 are rotated 80 degrees relative to the ground with the central axis of the rotating groove 38 at the lower end of the assisting crutch standing component 3 as the rotation axis. The reason for designing it to rotate 80 degrees at this time is to prevent the crutch from hitting the elderly due to inertia by directly rotating 90 degrees. Afterwards, on this basis, the crutch handle is grasped and exerted force to make the other crutches except the assisting crutch standing component 1 and the assisting crutch standing component 2 rotate another 10 degrees relative to the ground with the central axis of the rotating groove 38 at the lower end of the assisting crutch standing component 3 as the rotation axis. At the same time, since the anti-reversal ratchet 42 is stuck in the auxiliary rib 43 inside the assisting crutch standing component 3, the anti-reversal ratchet 42 is driven by the assisting crutch standing component 3 26 relative to the transmission The 36-tooth ratchet on the right end of gear four 39 rotates counterclockwise by 1 tooth, and during the rotation and dislocation process, the transmission gear four 39 slides to the left along the fixing screw 41 under the action of the anti-reverse ratchet 42. Under the tension of the spring 40, after the anti-reverse ratchet 42 rotates counterclockwise by 1 tooth relative to the 36-tooth ratchet on the right end of the transmission gear four 39, the anti-reverse ratchet 42 and the 36-tooth ratchet on the right end of the transmission gear four 39 resume their previous engagement state. At this point, after the above steps, the crutch is rotated from 0° relative to the ground when it falls to 90° relative to the ground when it is not fallen, so that the elderly can easily stand up with the crutch without bending over when the crutch falls. There is currently no crutch for the elderly with this function, which makes up for the shortcomings of the existing technology.
