[0001] This utility model relates to the field of rehabilitation equipment technology, and in particular to an elderly gait trainer. Background Technology

[0002] Currently, Chinese Patent Publication No. CN201426942Y discloses a parallel bar for gait training, which includes a base platform. Two sets of telescopic adjustable support rods are fixedly installed on the base platform. Adjustable crossbars are horizontally inserted at the extended ends of each support rod and positioned by corresponding fastening screws. Two parallel handrails are set through the two sets of adjustable crossbars. A combined gait correction walking platform is set on the base platform. This discloses a training device with a general existing structure. However, when elderly people in rehabilitation centers take turns using it, they need to repeatedly adjust the height of the handrails. The existing handrails need to be adjusted by fastening screws, which is slow and inconvenient. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes an elderly gait trainer, which solves the technical problem that the existing handrails need to be adjusted by fastening screws, which is slow and inconvenient.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an elderly gait trainer, comprising a base frame, rotating rollers disposed on both sides of the base frame, a running belt disposed on the outer side of the rotating rollers, a drive device for driving one of the rotating shafts to rotate, and a base plate disposed on the base frame for supporting the running belt, and further comprising adjustable handrails disposed on the front and rear sides of the base frame, wherein the adjustable handrails comprise guide frames fixed on the front and rear sides of the base frame, a movable plate slidably disposed within the guide frames, a handrail rod disposed on the top surface of the movable plate, a rack fixed in the middle of the guide frames, a pawl rotatably disposed on the movable plate and engaging with the rack, and a spring disposed on the movable plate for engaging the pawl with the rack.

[0005] Furthermore, a cylinder is provided on the side of the pawl away from the moving plate, a mounting block is provided on the moving plate, an elastic sheet is provided on the mounting block for fitting with the cylinder, a contact part bent into a triangle is provided on the elastic sheet near the cylinder, and a reset block is provided at the bottom of the guide frame for contacting the elastic sheet.

[0006] Furthermore, the mounting block is internally screwed with a threaded post, and a rubber block is provided on the side of the threaded post away from the pawl.

[0007] Furthermore, a suspension frame is provided on one side of the base frame, a take-up reel is rotatably connected to the middle of the suspension frame, multiple pulleys are provided on the top of the suspension frame, a connecting line connected to the pulley is provided on the outer side of the take-up reel, a hanging plate is provided on the side of the connecting line away from the take-up reel, and a drive mechanism for driving the take-up reel to rotate is provided in the middle of the suspension frame.

[0008] Furthermore, the drive mechanism includes a worm gear rotatably disposed in the middle of the suspension frame, a worm wheel rotatably disposed on the suspension frame and cooperating with the worm gear, and a handwheel disposed on one side of the worm gear, wherein the worm wheel is connected to the take-up reel.

[0009] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0010] This gait trainer for the elderly utilizes a pawl mechanism. When the handrail height needs adjustment, pulling the handrail upwards causes the pawl on the moving plate to move upwards, separating it from the teeth on the rack. Once the handrail is adjusted to the appropriate height, the pawl re-engages with the rack under spring pressure, securing the moving plate and handrail. This allows for quick handrail height adjustment, enabling users of different heights to adjust quickly. It solves the problem of existing handrails requiring adjustment via screws, which is slow and inconvenient. Attached Figure Description

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] refer to Figures 1 to 8This embodiment provides an elderly gait trainer, including a base frame 1, rotating rollers 2 on both sides of the base frame 1, a running belt 3 on the outside of the rotating rollers 2, a drive device 4 for driving one of the rotating shafts to rotate, and a base plate 5 on the base frame 1 for supporting the running belt 3. It also includes adjustable handrails 6 on the front and rear sides of the base frame 1. The adjustable handrails 6 include guide frames 601 fixed on the front and rear sides of the base frame 1, a movable plate 602 slidably disposed in the guide frame 601, a handrail 603 on the top surface of the movable plate 602, a rack 604 fixed in the middle of the guide frame 601, a pawl 605 rotatably disposed on the movable plate 602 and cooperating with the rack 604, and a spring 606 disposed on the movable plate 602 for engaging the pawl 605 with the rack 604.

[0021] When adjusting the handrail height, pull the handrail upwards. This will move the pawl on the moving plate upwards, separating it from the teeth on the rack. Once the handrail is adjusted to the appropriate height, the pawl will re-engage with the rack under the action of the spring, securing the moving plate and handrail. This allows for quick adjustment of the handrail height, enabling users of different heights to adjust quickly. This is especially beneficial when multiple people need to take turns using the handrail in a rehabilitation center.

[0022] The pawl 605 has a cylinder 607 on the side away from the moving plate 602. The moving plate 602 has a mounting block 608. The mounting block 608 has an elastic sheet 609 for fitting with the cylinder 607. The elastic sheet 609 has a contact part 610 bent into a triangle near the cylinder 607. The bottom of the guide frame 601 has a reset block 611 for contacting the elastic sheet 609.

[0023] The elastic plate is designed so that when the handrail height needs to be readjusted, the handrail is pulled to its highest position. The width of the topmost rack of the guide frame is greater than the width of the bottom rack. When the pawl contacts the top rack, the pawl will rotate, causing the cylinder to engage with the elastic plate contact part near the mounting block. The contact force of the elastic plate contact part will prevent the pawl from engaging with the rack under the action of the spring. At this point, it moves down, and the pawl will not engage with the rack. When it moves to the bottom, the elastic plate engages with the reset block, and the pawl rotates under the action of gravity. The middle position of the pawl cylinder fits against the contact part of the elastic plate. When the pawl approaches the rack, the spring force will cause the pawl to re-engage with the rack, restoring the locking function and facilitating the adjustment of the handrail height.

[0024] The mounting block 608 is internally screwed with a threaded post 612. A rubber block 613 is provided on the side of the threaded post 612 away from the pawl 605. With the threaded post in place, after the height of the handrail is fixed, the rubber block can be rotated, and the rubber block drives the threaded post to rotate. The threaded post is screwed on the side close to the pawl, which limits the position of the pawl and helps to restrict the handrail from moving upward, making it convenient for use when the limbs are not coordinated.

[0025] A suspension frame 7 is provided on one side of the base frame 1. A take-up reel 8 is rotatably connected to the middle of the suspension frame 7. Multiple pulleys 9 are provided on the top of the suspension frame 7. A connecting line 10 connected to the pulley 9 is provided on the outside of the take-up reel 8. A hanging plate 11 is provided on the side of the connecting line 10 away from the take-up reel 8. A drive mechanism for driving the take-up reel 8 to rotate is provided in the middle of the suspension frame 7. The drive mechanism includes a worm gear 12 rotatably provided in the middle of the suspension frame 7, a worm wheel 13 rotatably provided on the suspension frame 7 and cooperating with the worm gear 12, and a handwheel 14 provided on one side of the worm gear 12. The worm wheel 13 is connected to the take-up reel 8.

[0026] The drive mechanism is designed so that when an elderly patient is unsteady on their feet, ropes are threaded through both sides of the suspended platform and tied to the patient. Then, the handwheel is rotated. The first handwheel drives the worm gear to rotate, which in turn drives the worm wheel at the bottom to rotate. The worm wheel then drives the take-up reel to rotate. The take-up reel tightens and loosens the connecting line, allowing the height of the suspended platform to be adjusted. This design prevents elderly patients from falling due to insufficient arm strength.
