Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a highly stable walking aid device capable of walking on slopes. Background Art

[0002] Walking aids are mainly divided into two types: non-wheeled and wheeled. The non-wheeled type is moved forward step by step with both hands, featuring good stability and the height can be adjusted arbitrarily according to the user's height. It is mainly used for patients with perfect upper limb functions and relatively minor lower limb function injuries. The non-wheeled walking frame is further divided into fixed type, folding type and differential stepping type. Among them, the fixed type has good stability and low price, the folding type is convenient for transportation and storage, and the differential stepping type moves the walking aid forward by alternating hands, with high stability. The wheeled walking frame is equipped with casters, and the walking aid never leaves the ground during walking. Due to the small frictional resistance of the wheels, it is easy to push and move. It is suitable for users with lower limb dysfunction who cannot lift the walking frame to move forward, but its stability is slightly poor. The wheeled walking frame is further divided into various forms such as two-wheeled, three-wheeled, and four-wheeled;

[0003] However, no matter which existing walking aid device is used, it is only suitable for use on flat ground. When going downhill, the walking aid device may get out of control and tip over, which will cause the walking aid device to lose its supporting function and even cause the user to fall and get injured.

[0075] The limiting rod 322 is located below the rack 321. The limiting rod 322 is fixedly connected to the rack 321. The bottom end of the limiting rod 322 abuts against the upper end surface of the limiting block 145, and the limiting rod 322 limits the limiting block 145.

[0076] The working principle of the present invention:

[0077] When walking on a flat road, the state is as Figure 1 , 2 shown. At this time, the push rod 110 is in a horizontal state, and the control rod 210 abuts against the latch rod 220, so that the latch head 223 on the latch rod 220 is always stuck on the limiting tooth 131 on the cross frame 130. Furthermore, the handrail frame 120 cannot rotate around the cross frame 130, and the position of the push rod 110 is thus fixed and will not rotate. Moreover, the bottom end surface of the limiting rod 322 at the lower end of the limiting device 320 abuts against the upper end surface of the limiting block 145, so that the walking wheel 146 always contacts the ground. When walking on a flat road, the walking wheel 146 can assist the user to push forward, making the pushing easier;

[0078] When going downhill, the user rotates the control lever 210 upward and unscrews it by a certain distance so that the lower part of the control lever 210 no longer limits the clamping rod 220. At this time, when the push rod 110 is pulled backward, the push rod 110 will start to rotate around the cylinder three 134 on the cross frame 130. At the same time, through the cooperation of the rotating block 113 on the push rod 110 and the notch two 122 on the armrest frame 120, the armrest frame 120 rotates relative to the round hole three 132 on the cross frame 130 at the same time. During the rotation of the armrest frame 120, the clamping rod 220 inside the armrest frame 120 moves up and down repeatedly under the combined action of the spring 230 and the limiting teeth 131 to facilitate controlling the rotation angle of the armrest frame 120. When the armrest frame 120 rotates, the armrest frame 120 will drive the elliptical turntable two 260 to rotate through the cylinder one 125. The rotation of the elliptical turntable two 260 will further drive the elliptical turntable one 240 and the elliptical turntable three 280 to rotate into the inside of the cross frame 130 through the rotating rod one 250 and the rotating rod two 270. After the elliptical turntable one 240 and the elliptical turntable three 280 rotate, they will drive the front leg 140 and the rear leg 150 to rotate outward around the cylinder four 135 or the cylinder two 133. The outward rotation of the front leg 140 and the rotating rod one 250 will increase the distance between the bottom ends of the front leg 140 and the rear leg 150, which can further improve the stability of the entire walking aid device. While the front leg 140 rotates around the cylinder four 135, the gear 310 above the front leg 140 will start to rotate under the action of the gear ring 136. After the gear 310 rotates, due to the meshing of the rack 321 on the limiting device 320 and the gear 310, the limiting device 320 will drive the entire limiting device 320 to move upward, and the bottom end of the limiting rod 322 will be separated from the limiting block 145, causing the limiting block 145 to drive the walking wheel 146 to move upward relative to the notch six 144 under the pressure of the entire walking aid device until the bottom end of the front leg 140 touches the ground and stops. At this time, the walking wheel 146 is separated from the ground, and the bottom end of the front leg 140 touches the ground, changing the rolling contact to sliding contact, which can improve the stability of the entire walking aid device in contact with the slope. When the bottom end of the front leg 140 completely touches the ground and the armrest frame 120 rotates to a certain angle, the push rod 110 stops rotating, and then the control lever 210 is screwed downward so that the bottom end of the control lever 210 presses against the first clamping block 221 on the clamping rod 220. Then the clamping rod 220 makes the clamping head 223 at the lower end of the clamping rod 220 tightly press against the limiting teeth 131 on the cross frame 130, thereby realizing the re-fixation of the armrest frame 120 and the cross frame 130 and completing the slope deformation of the entire walking aid device.
