Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a mobile training frame for elderly care. Background Technology

[0002] Lower limb walking function training is a crucial part of geriatric rehabilitation care, significantly contributing to maintaining or restoring mobility, preventing falls, and improving quality of life. Portable training frames, as a common assistive device, are favored for their ease of use in different locations, especially for elderly patients who require frequent adjustments to their training position or need to be transferred between training sessions.

[0003] The existing technology has the following shortcomings: The existing technology disclosed in CN221888679U discloses an assistive walking training device for elderly care, which "includes a bracket, the bracket is H-shaped, a connecting plate is fixedly installed between the two sides of the lower part of the bracket, a support plate is fixedly installed at the bottom of the bracket, a caster wheel is fixedly installed below the support plate, a support frame is movably installed above the bracket, a pad is fixedly installed above the support frame, a handle is fixedly installed on the inner side of the pad, an adjustment component is fixedly installed in the middle of the bracket, a foot plate is fixedly installed at the output end of the adjustment component, and a seat plate is provided in the middle of the bracket, the seat plate is rotatably connected to the bracket"; While the casters at the bottom of the aforementioned training device facilitate overall transport and repositioning, they also pose significant safety hazards during walking training. When a patient attempts to walk while holding onto the training frame, the device moves as a whole with the patient's push. This movement is often uncontrollable, easily causing the patient to lose balance due to the device slipping, leading to a risk of forward or backward falls. This risk is particularly pronounced for elderly patients with weak lower limb strength and poor balance. Furthermore, standard mobile training frames require sufficient space for the patient to push the device. In confined hospital wards, home environments, or crowded rehabilitation areas, this requirement is often difficult to meet, limiting the widespread application of the device. Additionally, the mode of walking by pushing the device differs from natural stationary stepping or treadmill training, making it difficult to precisely control stride length, cadence, and training intensity, which is detrimental to standardized gait training and muscle strengthening exercises.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] This utility model provides a technical solution: such as Figure 2 and Figure 6 As shown in this embodiment, a mobile training frame for elderly care includes a base 1. A controller is installed on the top of the base 1 to control the electric telescopic rod 4 and the drive motor 18. Multiple sets of limiting posts 2 are symmetrically installed on the top of the base 1 to limit the movement of the limiting frame 10 and ensure its vertical movement. An adjustment component is installed above the base 1 to adjust the position of the silicone pad 14. A training component is installed above the base 1 to assist the elderly in completing walking training. Two sets of limiting holes are opened on the top surface of the base 1 to limit the movement of the third lead screw nut 20 and ensure its horizontal movement. Storage cavities 3 are opened at the four corners of the bottom of the base 1 to store the casters 5 and ensure the stability of the equipment during use. The electric telescopic rod 4 is installed in the storage cavity 3 by bolts, and the height of the casters 5 can be adjusted. The output end of the electric telescopic rod 4 is equipped with casters 5, which facilitates the user to adjust the position of the training equipment and facilitates the use of the training equipment in different locations.

[0018] like Figure 2 and Figure 3As shown, the adjustment assembly includes a fixing frame 6, which is bolted to the top of the base 1. A first lead screw 7 is rotatably installed inside the fixing frame 6. A handwheel is provided at the end of the first lead screw 7 for adjusting the position of the first lead screw nut 8, thereby adjusting the height of the silicone pad. A first lead screw nut 8 is sleeved on the outside of the first lead screw 7. A fixing plate 9 is bolted to the side wall of the first lead screw nut 8. Limiting brackets 10 are installed at both ends of the side wall of the fixing plate 9 for limiting the second lead screw nut 12 to ensure the horizontal movement of the second lead screw nut 12. A second lead screw 11 is rotatably installed inside the limiting bracket 10. A handwheel is provided at the end of the second lead screw 11. The first screw nut 8 and the second screw nut 12 are fitted with a second screw nut 12. A connecting plate 13 is bolted to the side wall of the second screw nut 12. A silicone pad 14 is installed on the side wall of the connecting plate 13. A strap 15 is symmetrically installed on the side wall of the silicone pad 14 for securing the elderly person's waist, preventing the elderly person from leaning forward or backward, and ensuring the elderly person's safe training. The surfaces of the fixing frame 6 and the limiting frame 10 are both opened with sliding openings. The first screw nut 8 and the second screw nut 12 are both slidably set with the sliding openings. The limiting frame 10 is slidably fitted on the outside of the limiting post 2. The surface of the strap 15 is provided with Velcro. With the setting of the adjustment component, the position of the silicone pad can be adjusted according to the elderly person's height and body shape, which is convenient for different elderly people to use for training.

[0019] like Figure 4 and Figure 5As shown, the training assembly includes multiple sets of limiting plates 16 and drive motors 18. The limiting plates 16 are symmetrically mounted on the top of the base 1 using bolts. Each limiting plate 16 has a limiting groove 17 on its surface to limit and guide the sliding of the limiting rod 25, thereby causing the foot pedal 26 to rise in an arc shape and then slide back to its original position. The drive motor 18 is bolted to the inner wall of the limiting opening on the surface of the base 1 and is used to drive the movement of the reciprocating screw 19, thereby moving the foot pedal 26. The output end of the drive motor 18 is equipped with the reciprocating screw 19 to ensure the reciprocating movement of the foot pedal 26. A third screw nut 20 is sleeved on the outside of the reciprocating screw 19, and a connector 21 is mounted on the top of the third screw nut 20. The limiting groove 17 includes a horizontal groove and an arc-shaped groove. One end of the horizontal groove and the arc-shaped groove are connected together, and the other end of the horizontal groove and the arc-shaped groove have a height difference. The length of the reciprocating screw 19 corresponds to the length of the horizontal groove. The connector 21 has an L-shaped cross-section. A limiting frame 22 is installed at one end of the connector 21 to limit the movement of the fixed cylinder 23, thereby limiting the movement of the foot pedal 26. The fixed cylinder 23 is slidably installed inside the limiting frame 22 to limit the limiting rod 25. A spring 24 is installed inside the fixed cylinder 23 to ensure that the limiting rod 25 slides along the trajectory of the limiting groove 17. The limiting rod 25 is installed at one end of the spring 24 and is slidably disposed with the limiting groove 17. A foot pedal 26 is installed between the fixed cylinders 23 for the elderly to place their feet. The surface of the foot pedal 26 is provided with anti-slip protrusions. With the training component, the elderly only need to stand on the foot pedal 26 to complete the cyclical walking training, reducing safety hazards during the training process. At the same time, the walking training is not limited by space, realizing standardized gait training and muscle strength exercise for the elderly.

[0020] This utility model provides a mobile training frame for elderly care, the specific working principle of which is as follows: In the initial state, the casters 5 are outside the storage cavity 3, allowing the user to directly move the training equipment to the desired location. Then, the electric telescopic rod 4 is activated, causing the casters 5 to rise and retract into the storage cavity 3, ensuring the base 1 is in contact with the ground and guaranteeing the stability of the training equipment. During walking training, the user stands above the foot pedal 26 and then rotates the first lead screw 7 and the second lead screw 11 according to the user's height and build. The rotation of the first lead screw 7 causes the first lead screw nut 8 to move... The movement of the first lead screw nut 8 causes the fixed plate 9 to move, which in turn causes the connecting plate 13 and the silicone pad 14 to move, allowing adjustment of the height of the silicone pad 14. The rotation of the second lead screw 11 causes the second lead screw nut 12 to move, which in turn causes the connecting plate 13 to move, which in turn causes the silicone pad 14 to move, allowing adjustment of its front-to-back position. After adjusting the position of the silicone pad 14, the strap 15 can be used to secure it. With the user's waist supported, ensuring a stable standing position, the drive motor 18 is then started. The two sets of drive motors 18 operate intermittently, with one set operating while the other remains stationary. The drive motor 18 drives the reciprocating lead screw 19 to rotate. The rotation of the reciprocating lead screw 19 causes the third lead screw nut 20 to move forward and then return to its original position. The forward movement of the third lead screw nut 20 causes the connecting piece 21 and the limiting frame 22 to move. At this point, the limiting rod 25 is located within one end of the arc-shaped groove. The movement of the limiting frame 22 causes the limiting rod 25 to remain within the limiting groove 1. The foot pedal 26 slides within the arc-shaped groove of the limiting groove 17. When passing through the arc-shaped groove of the limiting groove 17, the fixed cylinder 23 slides within the limiting frame 22, causing the foot pedal 26 to rise and move forward, and the spring 24 to be compressed. When the third lead screw nut 20 resets, the limiting rod 25 slides along the transverse groove of the limiting groove 17, causing the foot pedal 26 to reset. Finally, under the reset force of the spring 24, it is locked back into the arc-shaped groove. This cycle repeats to assist the user in completing walking training. The user can adjust the speed of the drive motor 18 as needed to change the step frequency.
