Description

Technical Field

[0001] This invention relates to the field of assistive devices for the elderly, specifically to a structure for a standing safety device for the elderly. Background Technology

[0002] Neurology is a subspecialty of neurology, primarily treating cerebrovascular diseases, migraines, inflammatory brain diseases, myelitis, epilepsy, dementia, metabolic diseases and genetic predispositions, trigeminal neuralgia, sciatica, peripheral neuropathy, and myasthenia gravis. In the later stages of Alzheimer's disease, if the condition is severe, symptoms such as limb stiffness, slow movement, unsteady gait, and frequent falls may occur. This is because many brain cells are damaged or dead, thus affecting mobility. Medication is necessary, along with appropriate exercise such as walking and listening to music. To ensure that the elderly can get up normally, some designers have developed assistive mechanisms for getting up. These mechanisms are mostly installed on the bed or chair surface and use external force to provide assistance to the elderly's hips, helping them to get up.

[0003] However, in actual use, we found that most existing standing devices can only assist elderly people in sitting positions to get up. When it is necessary to assist elderly people in lying positions to get up, most elderly people need to be equipped with a separate standing device for lying positions. This means that when going out, they need to carry two standing devices, which not only increases the tools they need to carry and increases the burden of exercise for the elderly, but also provides no protection when getting up and requires assistance from caregivers. Therefore, we propose a standing protection device structure for the elderly. Summary of the Invention

[0004] The purpose of this invention is to provide a structure for a standing safety device for the elderly, in order to solve the problems mentioned in the background art.

[0049] The back panel 15 is equipped with side guards 6, which can be used to protect the elderly when they get up.

[0050] The side guard 6 includes a fixed shaft 61 on both sides of the back plate 15. A side plate 62 is rotatably mounted on each fixed shaft 61. A torsion spring 63 is mounted on each fixed shaft 61. The two ends of the torsion spring 63 are connected to the fixed shaft 61 and the side plate 62 respectively. A through groove 64 is provided on each side plate 62. A fixing groove 41 is provided on each side plate 62. It can be folded up in use.

[0051] The fixed base 13 is equipped with a switching component 7, which can drive the back plate 15 and the thigh plate 16 to rotate respectively, thereby completing the task of getting the elderly up.

[0052] The switching assembly 7 includes a second rotating shaft 71 rotatably mounted on a fixed base 13, a stock plate 16 mounted on the second rotating shaft 71, and two driving members 8 respectively used to cooperate with the first rotating shaft 52 and the second rotating shaft 71 in the fixed groove 41, so as to drive the first rotating shaft 52 and the second rotating shaft 71 to rotate respectively.

[0053] The driving component 8 includes a third push rod 81 mounted on the positioning rod 72. A connecting seat 82 is slidably mounted on the end of the third push rod 81. An upper rack 83 and a lower rack 84 are respectively mounted on the top two ends of the connecting seat 82. A lower gear 85 and an upper gear 86 that cooperate with the lower rack 84 and the upper rack 83 are respectively mounted on the first rotating shaft 52 and the second rotating shaft 71.

[0054] Positioning rods 72 are provided on both sides of the fixed frame 42, and adjustment control 9 is provided on each positioning rod 72. The rotation adjustment of the back plate 15 and the thigh plate 16 can be controlled by the adjustment control 9 respectively.

[0055] The adjustment control 9 includes irregularly shaped slide rails 91 on both sides of the fixed base 13. Each connecting base 82 is provided with a protruding post 92, which is movably disposed in the irregularly shaped slide rail 91. Each connecting base 82 is provided with a spring 93, and each spring 93 is provided with a positioning plate 94 that is slidably disposed on the connecting base 82. Each positioning plate 94 is provided with a roller 95 at its bottom. The irregularly shaped slide rail 91 is shaped like a "J". The upper position is used for the upper rack 83 and the upper gear 86 to mesh, and the lower position is used for the lower gear 85 and the lower rack 84 to mesh. The inclined position in the middle is used for switching between the two. The protruding post 92 is located in the initial unused state and the resting state after use.

[0056] The fixed base 13 is equipped with a storage battery 43 and a controller 44. The first push rod 35, the second push rod 51 and the third push rod 81 are all electrically connected to the storage battery 43 and the controller 44.

[0057] When in use, caregivers remove the fixed seat 13 from the walking aid body 1, place it on the chair or bed where the elderly person is lying, and help the elderly person sit on the fixed seat 13.

[0058] If it is on the chair surface, the second push rod 51 drives the fixing frame 42 to move backward, so that the protrusion 92 on the connecting seat 82 moves to the top along the inclined position of the irregular slide rail 91. At this time, the upper rack 83 can mesh with the upper gear 86. The third push rod 81 drives the connecting seat 82 to move along the upper position of the irregular slide groove. The elderly person's hand is held on the walking aid body 1. During this process, the upper rack 83 drives the upper gear 86 to rotate, which in turn drives the rotating shaft 71 and the thigh plate 16 to rotate, so as to realize the elderly person's standing up action. After the elderly person stands up, the protruding rod 21 on the fixing seat 13 cooperates with the positioning groove 22 to place the fixing seat 13 on the walking aid body 1 for easy carrying.

[0059] If placed on a bed, after being positioned under the elderly person's body, the second push rod 51 is activated to move the fixing frame 42 forward, causing the protrusion 92 on the connecting seat 82 to move oriented to the bottom along the inclined position of the irregular slide rail 91. At this time, the lower rack 84 can mesh with the lower gear 85. After the back plate 15 extends, its side wall will rotate inward synchronously under the action of the torsion spring 63 to protect the elderly person when getting up. Then, the third push rod 81 is used to drive the connecting seat 82 to move along the lower position of the irregular slide groove. During this process, the lower rack 84 drives the lower gear 85 to rotate, thereby driving the rotation... The rotating shaft 52 and back plate 15 rotate to enable the elderly to get up. Then, the first push rod 35 is activated to drive the main rack 32 to move, which in turn drives the main gear 34 and main shaft 33 to rotate, thereby rotating the fixed seat 13 so that the position of the leg plate 16 is facing one side of the bed. Then, the operation can be repeated as if on a chair. Because it is relatively inconvenient for the elderly to get in and out of bed, the height of the bed where the elderly sleep is generally relatively low. When the elderly get up, the fixed seat 13 is placed on the walking aid body 1 by the cooperation of the protruding rod 21 on the fixed seat 13 and the positioning groove 22, making it easy to carry.
