Due to the decline of physical functions, weakened muscle strength, decreased joint flexibility and poor balance, the elderly often face great difficulties when converting from a sitting or lying position to a standing position, and may even fall due to unstable standing, leading to serious consequences such as fractures and craniocerebral injuries. Currently, the existing assistance standing devices on the market have many limitations. Some traditional assistance standing devices have simple structures and lack the adjustment function for the elderly with different body shapes and heights, making it difficult to meet diverse usage requirements. For example, the support structure with a fixed spacing will cause cramped space and a sense of oppression for the elderly with a larger body size; while for the elderly with a smaller body size, it cannot provide sufficient stable support, posing a safety hazard. At the same time, most devices have deficiencies in anti-fall protection. Relying only on simple handrails or fences, they cannot quickly and effectively provide protection when the elderly suddenly lose their body balance, and cannot fundamentally reduce the risk of the elderly falling and getting injured.

Protective component An arm support seat 16 is installed in the center of the upper surface of the fixed plate 11. The flexible pad 18 at its upper end provides a comfortable support for the elderly's arm; the grip 17 on the front surface of the upper end of the fixed plate 11 is convenient for the elderly to hold and helps to maintain balance. Anti-fall component The anti-fall component is composed of multiple parts. The first rotating motor 14 is installed at the rear end inside the fixed plate 11. Its output end is connected to the screw rod 39. The screw rod 39 is arranged in the sliding groove opened on the opposite inner surfaces of the fixed plate 11. The slider 40 is threadedly sleeved on the outer end of the screw rod 39 and can slide in the sliding groove. The front end of the slider 40 is hinged to the scissor fork 41. The front end of the scissor fork 41 is connected to the mounting plate 36. The front end of the mounting plate 36 is fixed with a waist protection arc plate 37. A flexible pad is provided inside the waist protection arc plate 37 for buffering and protection. At the same time, fixing seats 34 are installed on both sides of the outer end of the sliding groove opened on the fixed plate 11.

The buckles 38 at both ends of the waist protection arc plate 37 can be fixed after it fits the elderly's waist. When the elderly are in danger such as losing balance, the anti-fall component can protect the safety of the elderly.

[0027] Instructions for use The universal wheels 6 at the bottom of this assisted standing device endow it with flexible mobility. Caregivers can easily push the device to the positions where the elderly need to stand, such as beside the bed or the sofa. The armrests 7 on the top plate 2 are convenient for the elderly to grasp and get leverage. The placement groove 8 and the water cup groove 9 enable the elderly to place their personal items and drink water before and after standing, avoiding instability caused by reaching for items. The elderly can control each functional component of the device through the control panel 10 to prepare for the standing process. The adjustment component is installed in the center of the inner part of the front plate 1, and its operation revolves around the bidirectional motor 29. When the elderly are ready to use the device to stand, the caregiver or the elderly starts the bidirectional motor 29 through the control panel. The power at both ends of the motor is transmitted to the driving gear disk 31 through the connecting rod 30. The driving gear disk 31 rotates and drives the chain 32 to run. The chain 32 is connected to the linkage gear disk 27, and the linkage gear disk 27 drives the second rotating rod 25 to rotate. The driven gear disk 26 on the second rotating rod 25 meshes with the tooth block at the front end of the guide block 24, thereby pushing the guide block 24 to slide in the through groove of the limit block 23. Since the rear end of the guide block 24 is connected to the first support column 3, the sliding of the guide block 24 realizes the adjustment of the distance between the two first support columns 3. According to the body type of the elderly, the distance can be flexibly adjusted. For example, for an elderly person with a larger build, increasing the distance can make them stand more comfortably;For an elderly person with a thin build, reducing the spacing can provide more stable support, ensuring a suitable activity space for the elderly person inside the device. To prevent the elderly person from falling due to physical exhaustion, sudden loss of balance, etc. during standing, the anti-fall component can be activated in advance through the control panel 10. The rotation motor 1 starts to work, and its output drives the screw rod 39 to rotate in the chute of the fixed plate 11. The slider 40 is threadedly sleeved on the outer end of the screw rod 39. As the screw rod 39 rotates, the slider 40 slides axially in the chute. The scissor fork 41 hinged at the front end of the slider 40 changes its angle accordingly, pushing the mounting plate 36 to move back and forth. The lumbar arc plate 37 at the front end of the mounting plate 36 gradually approaches the waist of the elderly person. The flexible pad on the inner side of the lumbar arc plate 37 fits the body of the elderly person, providing buffering and support. At the same time, the telescopic rod 35 connected to the hinge seat at the front end of the fixed seat 34 plays an auxiliary support and stabilizing role to prevent the lumbar arc plate 37 from shaking. When the lumbar arc plate 37 is in place, it can be fixed through the latches 38 at both ends. During the standing process of the elderly person, if unstable situations such as forward leaning, backward leaning, or side tilting of the body occur, the anti-fall component can provide support in a timely manner, effectively preventing the elderly person from falling. If, after the elderly person stands, they feel that the height of the arm support seat 16 is not appropriate, the height of the fixed plate 11 can be adjusted through the linkage structure between the adjusting plate 4 and the support plate 12. The rotation motor 2 is activated, and its output drives the rotating rod 1 to rotate. The taper gear disks 1 on both sides of the outer end of the rotating rod 1 rotate accordingly. The taper gear disk 1 meshes with the taper gear disk 2, driving the gear disk at the rear end of the rotating rod to rotate. The gear disk meshes with the tooth blocks on both sides of the connecting plate 13, pushing the connecting plate 13 to move up and down, and then driving the support plate 12 to slide up and down in the opening of the adjusting plate 4, achieving the adjustment of the height of the fixed plate 11. In this way, regardless of the height of the elderly person, the arm support seat 16 can be adjusted to a suitable height, allowing the elderly person to place their arms naturally on the arm support seat 16, reducing the burden on the arms and increasing the comfort and stability during standing.;
