[0042] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0043] Reference Figures 1 to 4 As shown in the figure, this utility model embodiment provides a single-leg walking aid.

[0044] The single-leg walking aid includes a footrest 100, a support frame 200, and a support foot 300.

[0045] The support frame 200 is hinged to the foot bracket 100. The support frame 200 rotates around a horizontal axis. The support foot 300 is connected to the support frame 200 and changes position as the support frame 200 rotates.

[0046] In this embodiment, the support frame 200 rotates below the foot support 100, causing the support foot 300 to change position between below and behind the foot support 100.

[0047] Rotate the support frame 200 downwards and move the support foot 300 below the footrest 100 to switch the single-leg walking aid to a standing position.

[0048] Fold the support frame 200 toward the footrest 100. The support frame 200 moves the support foot 300 to the rear of the footrest 100, thus switching the single-leg walker to a sitting position.

[0049] The single-leg walking aid switches between sitting and standing positions.

[0050] When the patient needs to walk or stand, the single-leg walker is switched to the standing position, and the support frame 200 is rotated to rotate the support foot 300 to the bottom of the footrest 100 so that the patient can walk or stand in a kneeling position on one leg.

[0051] When the patient needs to sit down, the support frame 200 is folded towards the footrest 100, so that the support foot 300 rotates to the back of the footrest 100. That is, the support foot 300 rotates to the back of the patient's injured foot when the patient is in a kneeling position. When the patient is in a sitting position, the footrest 100 and the lower leg are approximately perpendicular to the ground, so the support foot 300 touches the ground and lifts the patient's injured foot, preventing the patient's injured foot from touching the ground.

[0052] Therefore, patients can use a single-leg walker for standing, walking, and sitting without having to disassemble the walker, making it more convenient for users.

[0053] In some embodiments, refer to Figures 1 to 4 As shown, the single-leg walker is also provided with a first locking member 400. The first locking member 400 is located at the bottom of the footrest 100. After the support frame 200 is folded into the footrest 100, it will contact the first locking member 400. Therefore, when the single-leg walker is switched to a sitting position, the first locking member 400 can be connected to the support frame 200, so that the support frame 200 is fixed to the bottom of the footrest 100.

[0054] When the patient is in a sitting position, the first locking member 400 is used to fix the support frame 200 to the bottom of the footrest 100 to prevent the support frame 200 from rotating relative to the footrest 100 and causing injury to the patient's injured foot.

[0055] In some embodiments, refer to Figures 1 to 4 As shown, the bottom of the first locking member 400 is provided with a buckle groove 410, which faces downward. After the support frame 200 is folded upward to the bottom of the foot bracket 100, at least a part of the support frame 200 is inserted into the buckle groove 410.

[0056] The support frame 200 is fixed by the buckle groove 410 of the first locking member 400, making it easier to fix and release the support frame 200, and allowing the patient to operate the support frame 200 to rotate to switch the use of the single-leg walking aid.

[0057] In some embodiments, refer to Figures 1 to 4As shown, the support frame 200 is provided with a rotating shaft 210, a support rod 220 and a telescopic rod 230. The rotating shaft 210 is connected to the foot bracket 100, the support rod 220 is hinged to the rotating shaft 210, the telescopic rod 230 is connected to the support rod 220, the telescopic rod 230 can extend and retract along the axis of the support rod 220, and the end of the telescopic rod 230 is connected to the support foot 300.

[0058] Reference Figure 1 and Figure 2 As shown, when the single-leg walker is in a standing position, the distance between the supporting foot 300 and the footrest 100 can be changed by the telescopic rod 230, thereby adapting to the distance from the patient's knee to the ground and ensuring that the patient stands stably.

[0059] Reference Figure 3 As shown, when the single-leg walker is in a sitting position, the footrest 100 is set vertically. The distance between the support foot 300 and the footrest 100 can be increased by extending the telescopic rod 230. Since the patient's injured foot is located below the footrest 100, the support foot 300 moves downward to ensure that the support foot 300 lifts the patient's injured foot and prevents the patient's injured foot from touching the ground.

[0060] In some embodiments, refer to Figures 1 to 4 As shown, the support frame 200 is also provided with a slider 240 and a diagonal brace 250. The slider 240 is slidably connected to the foot bracket 100 and slides in the front-back direction. The front end of the diagonal brace 250 is hinged to the support rod 220, and the rear end of the diagonal brace 250 is hinged to the slider 240.

[0061] When the single-leg walker is in a standing position, the slider 240 and the diagonal brace 250 work together to provide a forward thrust to the support rod 220, preventing the support rod 220 from rotating backward and causing the support force to fail.

[0062] In some embodiments, refer to Figure 2 As shown, the footrest 100 is provided with a sliding groove 110 extending forward and backward. The slider 240 is slidably connected to the sliding groove 110 and slides forward and backward along the sliding groove 110. The single-leg walker is also provided with a second locking member 500. The second locking member 500 is provided on the footrest 100 and is located on the sliding trajectory of the slider 240. When the single-leg walker switches to the standing position, the second locking member 500 abuts against the slider 240 to limit the freedom of the slider 240 to move backward, thereby preventing the diagonal brace 250 from rotating the support rod 220 backward.

[0063] The second locking element 500 prevents the slider 240 from moving backward, ensuring that the diagonal brace 250 provides forward thrust to the support rod 220, thus ensuring that the support rod 220 supports the foot bracket 100.

[0064] In some embodiments, refer to Figures 1 to 4 As shown, the single-leg walking aid also includes a walking cart (not shown in the figure) and a connecting frame 600. The connecting frame 600 is hinged to the footrest 100 and is detachably connected to the walking cart.

[0065] When the single-leg walker assists the patient to move on flat ground, the connecting frame 600 extends from the bottom of the footrest 100, and then the support frame 200 is folded toward the bottom of the footrest 100. The connecting frame 600 can be used to connect the footrest 100 to the walker, and the patient can use the walker to move on flat ground in a kneeling position on one leg.

[0066] When the walker is not in use, the connecting frame 600 is removed from the walker and folded toward the bottom of the footrest 100.

[0067] In some embodiments, refer to Figure 4 As shown, the connecting bracket 600 can be detachably connected to the foot bracket 100.

[0068] The connecting frame 600 can be detached from the footrest 100. The connecting frame 600 and the walker can be purchased separately as additional assistive devices.

[0069] In some embodiments, refer to Figures 1 to 4 As shown, the support leg 300 has a through hole 310 running from left to right in the middle.

[0070] The support foot 300 is provided with a through hole 310 so that the support foot 300 can deform appropriately during the support process, and provide cushioning during the patient's walking process to reduce the pressure on the lower leg above the injured foot.

[0071] In some embodiments, refer to Figures 1 to 4 As shown, two support legs are set at approximately a 300mm interval.

[0072] The two support legs 300 are spaced approximately apart. When the single-leg walker is switched to a sitting position, the patient's injured foot is positioned between the two support legs 300, allowing the support legs 300 to avoid obstructing the patient's injured foot. When the single-leg walker is switched to a standing position, the two support legs 300 work together to provide support, helping patients using the single-leg walker to walk steadily.

[0073] Specifically, refer to Figures 1 to 4 As shown, the single-leg walking aid is equipped with a footrest 100, a support frame 200, a support foot 300, a first locking member 400, a second locking member 500, a connecting frame 600, and a walking aid trolley.

[0074] The footrest 100 has a soft foot pad on top, which is used to contact the patient's calf to relieve discomfort in the calf.

[0075] The bottom of the foot bracket 100 is provided with two sliding grooves 110 extending in the front-back direction. The two sliding grooves 110 are symmetrically arranged on the left and right. The bottom of the foot bracket 100 is also provided with two receiving grooves, which are symmetrically arranged on the left and right.

[0076] Reference Figure 1 and Figure 2 As shown, the support frame 200 is provided with a rotating shaft 210, two support rods 220, a connecting rod, two telescopic rods 230, two sliders 240, and two diagonal braces 250. The rotating shaft 210 is connected to the foot bracket 100 and extends in the left and right direction. The two support rods 220 are symmetrically arranged on the left and right sides, and the top ends of the two support rods 220 are respectively hinged to the left and right ends of the rotating shaft 210. The two telescopic rods 230 are connected to the two support rods 220 one by one. The telescopic rods 230 can extend and retract along the axis of the support rods 220. There are two support feet 300, and the ends of the two telescopic rods 230 are connected to the two support feet 300 one by one.

[0077] The connecting rod is hinged to two support rods 220, and two sliders 240 are respectively set in two slide grooves 110. The sliders 240 slide back and forth along the slide grooves 110. The rear ends of the two diagonal braces 250 are hinged to the two sliders 240 respectively, and the front ends of the two diagonal braces 250 are hinged to the connecting rod, so that the front ends of the diagonal braces 250 are hinged to the support rods 220.

[0078] The second locking element 500 is provided on the foot bracket 100, as shown in the reference. Figure 2 As shown, the second locking member 500 is rotatably connected to the foot bracket 100. The second locking member 500 rotates about an axis extending in the left and right direction. The rotation trajectory of the second locking member 500 intersects the sliding trajectory of the slider 240. When the slider 240 moves to the front end of the slide groove 110, the user rotates the second locking member 500 so that the front end of the second locking member 500 abuts against the rear side of the slider 240 and the rear end of the second locking member 500 abuts against the bottom of the foot bracket 100. The second locking member 500 restricts the degree of freedom of the slider 240 to move backward, so that the diagonal brace 250 provides a forward thrust to the support rod 220, ensuring that the support rod 220 supports the foot bracket 100.

[0079] Reference Figure 1 and Figure 2 As shown, when the single-leg walker is in a standing position, the distance between the supporting foot 300 and the footrest 100 can be changed by the telescopic rod 230, thereby adapting to the distance from the patient's knee to the ground and ensuring that the patient stands stably.

[0080] Reference Figures 1 to 4As shown, the two receiving slots are located on the rotation trajectory of the two support rods 220 respectively. When the support rod 220 is rotated upward and folded to the bottom of the foot bracket 100, the support rod 220 is inserted into the receiving slot. A first locking member 400 is provided on the rear side of the receiving slot. A buckle groove 410 is provided at the bottom of the first locking member 400. The buckle groove 410 is used to lock the bottom end of the support rod 220.

[0081] Reference Figure 3 As shown, when the single-leg walker is in a sitting position, the footrest 100 is set vertically. The distance between the support foot 300 and the footrest 100 can be increased by extending the telescopic rod 230. Since the patient's injured foot is located below the footrest 100, the support foot 300 moves downward to ensure that the support foot 300 lifts the patient's injured foot and prevents the patient's injured foot from touching the ground.

[0082] The support foot 300 is a rubber pad, and the middle of the support foot 300 has a through hole 310 running in the left and right direction.

[0083] The single-leg walking aid is also equipped with a connecting frame 600 and a walking cart.

[0084] Reference Figures 1 to 4 As shown, the connecting frame 600 is provided with a hinge seat and a connecting rod. The hinge seat is detachably connected to the bottom of the foot bracket 100 by screws. The hinge seat is located between two support rods 220. The top of the connecting rod is hinged to the hinge seat. A baffle is provided on the front side of the hinge seat to limit the degree of freedom of the connecting rod to rotate forward.

[0085] The walker has a connecting hole for inserting a connecting rod. The side wall of the connecting rod has multiple pin holes spaced along the axis. Rotate the connecting rod so that it is perpendicular to the foot bracket 100. Then insert the connecting rod into the connecting hole of the walker to complete the assembly. Finally, use the pin of the walker to insert into the pin hole to fix the connecting rod, thus realizing the connection between the connecting rod and the walker.

[0086] The left and right side walls of the hinge seat are respectively provided with arc-shaped grooves, and the front and rear ends of the arc-shaped grooves are respectively provided with clearance holes. The width of the arc-shaped groove is smaller than the diameter of the clearance hole. The slide rod is placed in the arc-shaped groove, and the connecting rod is provided with a mounting hole for installing the slide rod. The mounting hole passes through the connecting rod in the left and right direction. The slide rod slides left and right along the mounting hole. Limit heads are respectively provided at the left and right ends of the slide rod. The outer diameter of the limit head is larger than the diameter of the slide rod. The diameter of the mounting hole, the outer diameter of the limit head, and the diameter of the clearance hole are matched.

[0087] When the slide bar slides to the left or right, the limiting head disengages from the clearance hole, allowing the slide bar to slide along the arc groove, thus enabling the connecting rod to rotate. When the slide bar moves to the clearance hole, it slides left or right, causing the limiting head to fall into the clearance hole. The limiting head and the clearance hole then cooperate, preventing the slide bar from sliding along the arc groove and thus stopping the connecting rod from rotating.

[0088] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
