Description

Technical Field

[0001] The present invention relates to the technical field of elderly assistance, and in particular to an elderly toilet-assisting standing device. Background Art

[0002] As one of the vulnerable groups, the elderly are deeply concerned about their various actions in society. Due to the weakening of various functions of the elderly, the elderly or patients with weak knees cannot stand easily after using the toilet due to limb behavior degeneration, knee joint degeneration and calcium deficiency. This often causes safety hazards such as unstable standing or tilting and falling, and usually requires someone to help. Standing is a crucial factor affecting the independence of activities in the daily life of the elderly. With the increase of age, many elderly people who have the ability to walk can only be trapped in chairs because of the lack of ability to stand. The elderly are unable to stand up from a sitting position and need the care of others, which seriously affects the physical and mental health of the elderly, and also creates a huge burden on the family and society.

[0003] Some toilet equipment for the elderly lacks sufficient stability when in use, especially when the elderly or users with limited mobility sit down or get up, the equipment is prone to tilt or accidents, which may cause the user to fall or get injured. Many traditional toilet-assistive devices are relatively simple in design and cannot effectively take into account the comfort of the elderly or users with limited mobility. There may be problems with uncomfortable support or posture adjustment. Due to their large size and fixed structure, toilet-assistive devices are often inconvenient to carry or transfer. This is very inconvenient for the elderly or users with limited mobility who need to change their use environment frequently. After using the toilet, the elderly or users with limited mobility need additional help to stand up smoothly. Traditional toilet-assistive devices often cannot effectively provide such support, resulting in users facing difficulties in standing up after using the toilet. Traditional toilet-assistive devices can generally only provide fixed support and cannot flexibly adjust posture according to the needs of the user, which may cause discomfort to the user. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a device for assisting the elderly in standing up when using the toilet, which solves the problems of poor stability, insufficient comfort, poor convenience, and lack of auxiliary standing up and posture adjustment functions in many traditional toilet equipment for the elderly, which may cause users to face the problems of falling, difficulty in standing up, and discomfort.

[0013] The present invention provides a toilet-assisting standing device for the elderly, which has the following beneficial effects: 1. The present invention has a space-saving and flexible folding design: the design of the device can fold all components (such as the lifting rail, curved hanger, upper body cushion, lower body seat ring, foot pedal, etc.) when not in use, saving space and avoiding occupying too much room or bathroom space. In particular, the upper body cushion and lower body seat ring in the curved fixed arm are inverted, which fully utilizes the space-saving effect of folding and storage, avoiding the excessive size of the equipment. Through the longitudinal displacement control of the rotating seat, the prying of the curved pry bar, and the push of the hydraulic rod, the entire device will be unfolded during use, and can be folded through the hydraulic system and linkage mechanism when not in use, reducing the volume and facilitating storage and carrying.

[0014] 2. The present invention has the coordination effect of the hydraulic system and the mechanical linkage system: a two-stage hydraulic system is adopted, and through the linkage of the first stage and the second stage, precise lifting force control can be provided. The first-stage hydraulic telescopic pushes the curved hanger and the lifting slide rail to rise, ensuring the stable lifting of the device. The second-stage hydraulic telescopic pushes the linkage column through the linkage frame to ensure that the rotating seat can be stable and undisturbed during rotation, while avoiding friction interference between the linkage frame and the rotating seat, increasing the stability and comfort of the structure, and the precise cooperation between mechanical parts such as the curved pry bar, linkage frame, rotating arm and boom enables each part of the device to be smoothly unfolded during operation, and the synergy between different parts ensures smooth overall movement. Especially during the lifting, rotating and folding process, the device will not have motion interference, ensuring that the user can get comfortable auxiliary support.

[0015] 3. The present invention has ergonomics and comfort in use: the reasonable layout and rotation design of the upper body cushion and the lower body seat can provide comfortable support for users when using the toilet, and adjust the posture with the lifting and rotation of the device, so that users can feel the maximum support and stability during the toilet process, especially the auxiliary operation when standing up, which significantly reduces the physical burden of the elderly or people with limited mobility. The design of the foot pedal and the lower body seat ensures that the user can place his feet comfortably when using the toilet, and ensures its stability during the folding process through mechanical linkage. In particular, the 180-degree rotation design of the seat helps to avoid interfering with the user's activities when folding, and effectively supports the user's body.

[0016] 4. The present invention combines a hydraulic system with manual rotation operation: the hydraulic system of the device provides automated lifting and displacement functions, but also retains the manual rotation adjustment function, ensuring that caregivers can manually rotate the curved fixed arm or adjust the structure as needed, providing more precise support and operation. This design not only improves the flexibility of use, but also adapts to different usage scenarios and needs. During the folding process of the equipment, the traction rod, pry bar and other mechanisms will automatically complete the corresponding actions, pushing the lower body seat ring to fold, allowing the user to smoothly detach from the seat ring, and the pushing force allows the user to return to an upright standing state. This process does not require complicated operations and can be easily completed by users and caregivers.

[0017] 5. Enhanced safety and comfort of the present invention: Through the precise mechanical structure and the linkage of the hydraulic system, the device can maintain extremely high stability during the lifting and rotation process, avoiding excessive tilting or sudden movement, and ensuring the safety of the user during the toilet. At the same time, the relative rotation design between the rotating seat and the linkage column of the device effectively avoids friction and interference between the rotating parts, further improving the safety and durability of the device. The design and installation of the rotating seat ensure that the device will not cause discomfort or harm to the elderly or people with limited mobility even when adjusting the posture and support, reducing the potential safety hazards caused by the movement or dislocation of mechanical parts.

The bottom wall of the lower body seat ring 19 is also rotatably connected to two linkage suspension rods 22 away from the linkage folding component 24. The linkage suspension rods 22 are relatively parallel to each other and their positions are relatively increased. The ends of the two linkage suspension rods 22 away from the lower body seat ring 19 are rotatably connected to the same foot pedal 23, and the side wall of the curved fixed arm 5 is also located below the rotating arm 7 and is fixedly connected with a ground support frame 25. When the elderly toilet standing aid device is not in use, the lifting rail 2 will be retracted into the slide frame 1, and the curved hanger 3 will also descend along with the retraction of the lifting rail 2.

When the elderly or the user is in use, the two-stage hydraulic rod 12 installed on the top of the slide frame 1 is opened at the same time. The two-stage hydraulic rod 12 has two stages of hydraulic telescopic ends. The output of the first stage telescopic end pushes the curved hanger 3 and the lifting rail 2 to rise along the internal slide structure of the slide frame 1.At the same time, the curved fixed arm 5 is also hung and fixed by the cylindrical boom 4 arranged between the curved hanger 3, and then follows the rise of the curved hanger 3.

[0023] Please see attached Figure 5 -Attached Figure 6 And attached Fig.10 and attached Fig.11The vertical transmission assembly 17 includes a slide 171 and a fixed suspension rod 172. The slide 171 is fixedly connected to the inner top wall of the curved fixed arm 5, and the fixed suspension rod 172 is slidably connected to the inner top wall of the curved fixed arm 5. A curved slide rod 173 is slidably connected inside the slide 171. The bottom end of the fixed suspension rod 172 is rotatably connected to a curved pry bar 174. One end of the curved pry bar 174 close to the rotating seat 16 is rotatably connected to the side wall of the rotating seat 16. One end of the curved slide bar 173 away from the rotating seat 16 is movably connected to the curved pry bar 20. The curved slide bar 173 is slidably connected to the side wall of the sliding groove 21 provided on the curved pry bar 20. The end of the curved pry bar 174 away from the rotating seat 16 is rotatably connected to a traction rod 175. The other end of the traction rod 175 is rotatably connected to the side wall of the fixed suspension rod 172. The longitudinal displacement of the rotating seat 16 will move the The power is transmitted to the curved pry bar 174 included in the vertical transmission assembly 17, and the curved pry bar 174 will also begin to pry along the end of the fixed suspension rod 172 due to the effect of the longitudinal displacement. At the same time, the fixed suspension rod 172 also begins to slide along the side wall of the curved fixed arm 5 due to the motion interference, and the prying end of the curved pry bar 174 pulls the traction rod 175 to form a lateral drag force, dragging the curved slide bar 173 to start lateral displacement along the slideway 171. The curved slide bar 173 also pushes the curved pry bar 20 and the sliding groove 21 installed at the end of the rotating arm 7 under the effect of the lateral displacement. The curved pry bar 20 also generates a prying force along the rotating arm 7 at the same time, prying the upper body cushion 8 to start rotating until it rests on the supporting frame 25 provided on the curved fixed arm 5, so that the upper body cushion 8 can be unfolded and used as the curved hanger 3 rises.

[0024] Please see attached Figure 1 -Attached Figure 6The linkage folding assembly 24 includes a traction rod 241 and a traction rod 242. One end of the traction rod 242 is rotatably connected to the bottom wall of the upper body cushion 8, and the other end of the traction rod 242 is rotatably connected to a curved pry bar 243. The middle part of the curved pry bar 243 is rotatably connected to the side wall of the lower body seat ring 19. One end of the traction rod 241 is rotatably connected to the side wall of a linkage suspension rod 22, and the other end of the traction rod 241 is rotatably connected to the curved pry bar 243. At one end away from the traction rod 3 242, the upper body cushion 8 unfolds and guides the motion work to the rotating suspension arm 18 through the linkage folding assembly 24. When the upper body cushion 8 rotates, the traction rod 3 242 included in the linkage folding assembly 24 will start to pull the curved pry bar 3 243 installed at its bottom end, and the curved pry bar 3 243 guides the traction force to the lower body seat ring 19, so that it starts to rotate 180 degrees along the rotating suspension arm 18, and the curved pry bar 3 243 43 forms a prying force under the drag of the traction rod three 242 to push out the traction rod two 241 installed on its prying end, so that the traction rod two 241 pushes the two linked suspension rods 22 to start rotating along the lower body seat 19, and at the same time, the foot pedal 23 provided for the user to step on and the lower body seat 19 for sitting or lying are unfolded at the same time. The person sits or lies on the lower body seat 19, leans on the upper body cushion 8 and steps on the foot pedal 23 to use the toilet. The caregiver can also manually rotate the curved fixed arm 5 at the same time to make it rotate along the fixed bearing one 6 at the bottom end of the suspended cylindrical suspension arm 4, and the user also changes the walking direction, and the rotating structure will not produce motion interference. At the same time, during the folding process, the lower body seat 19 also rotates and folds accordingly, and the elderly and the user will be separated from the lower body seat 19 during the folding process, and will be pushed by the driving force generated by the folding to form an upright state, which is convenient for the elderly and the disabled to assist in standing up after using the toilet.

[0025] Working principle: When the elderly toilet standing aid device is not in use, the lifting rail 2 will be retracted into the slide frame 1, and the curved hanger 3 will also drop with the retraction of the lifting rail 2. The upper body cushion 8 arranged in the curved fixed arm 5 will rotate along the rotating arm 7 and be folded inside the curved fixed arm 5, while the lower body seat 19 will be inverted on the inner side of the curved fixed arm 5, and the foot pedal 23 will be folded at the bottom of the lower body seat 19 along the linkage suspension rod 22. When the elderly or the user goes to the toilet, the two-stage hydraulic rod 12 installed on the top of the slide frame 1 is opened at the same time. The two-stage hydraulic rod 12 has two stages of hydraulic telescopic ends. The output of the first stage telescopic end pushes the curved hanger 3 and the lifting rail 2 to rise along the internal slide structure of the slide frame 1. At the same time, the curved fixed arm 5 is also hung and fixed with the cylindrical boom 4 arranged between the curved hanger 3, and then rises with the curved hanger 3. The secondary telescopic end of the two-stage hydraulic rod 12 is also pushed out after the first stage is completed. The linkage frame 13 fixed at its end transmits the rising thrust to the linkage column 14 slidably installed in the cylindrical boom 4. The fixed bearing 15 arranged at the bottom end of the linkage column 14 is previously embedded and fixed in the interior of the rotating seat 16, so that the linkage column 14 and the rotating seat 16 can form relative rotation, so as to prevent the linkage frame 13 and the linkage column 14 from affecting the rotation of the rotating seat 16 and the curved fixed arm 5. At the same time, the rotating seat 16 will also undergo longitudinal displacement following the push out of the linkage column 14, and the vertical transmission component 17 installed on the side wall of the rotating seat 16 will rotate the rotating seat 16 The vertical motion displacement is transmitted to the rotating arm 7 and the upper body cushion 8, and the longitudinal displacement of the rotating seat 16 transmits the motion force to the curved pry bar 174 included in the vertical transmission assembly 17. The curved pry bar 174 will also begin to pry along the end of the fixed suspension rod 172 due to the effect of the longitudinal displacement. At the same time, the fixed suspension rod 172 also begins to slide along the side wall of the curved fixed arm 5 due to the motion interference, and the prying end of the curved pry bar 174 pulls the traction rod 175 to form a lateral drag force, dragging the curved slide bar 173 to start lateral displacement along the slideway 171. The curved portion of the curved slide bar 173 also pushes the curved pry bar 20 and the sliding groove 21 installed at the end of the rotating arm 7 under the effect of the lateral displacement. The curved pry bar 20 also moves along the rotating arm 7 at the same time. The rotating arm 7 generates a prying force to pry the upper body cushion 8 to start rotating until it abuts against the abutting frame 25 provided on the curved fixed arm 5, so that the upper body cushion 8 can be unfolded and used as the curved hanger 3 rises. When the upper body cushion 8 is unfolded, the motion work is guided to the rotating suspension arm 18 through the linkage folding component 24. When the upper body cushion 8 rotates, the traction rod 3 242 included in the linkage folding component 24 will begin to pull the curved pry rod 3 243 installed at its bottom end, and the curved pry rod 3 243 will guide the traction force to the lower body seat ring 19, so that it starts to rotate 180 degrees along the rotating suspension arm 18, and the curved pry rod 3 243 forms a prying force under the drag of the traction rod 3 242 to push out the traction rod 2 241 installed at its prying end.The traction rod 241 pushes the two linkage suspension rods 22 to start rotating along the lower body seat 19, and at the same time, the foot pedal 23 provided for the user and the lower body seat 19 for sitting or lying are unfolded at the same time. The person sits or lies on the lower body seat 19, leans on the upper body cushion 8, and steps on the foot pedal 23 to use the toilet. The caregiver can also manually rotate the curved fixed arm 5 at the same time, so that it rotates along the fixed bearing 1 6 at the bottom end of the hanging cylindrical suspension arm 4. The user also changes the walking direction, and the rotating structure will not produce motion interference. At the same time, during the folding process, the lower body seat 19 also rotates and folds accordingly. The elderly and the user will be separated from the lower body seat 19 during the folding process, and will be pushed by the driving force generated by the folding to form an upright state, which is convenient for the elderly and the disabled to assist in standing up after using the toilet. The volume is also reduced by re-rotating and folding, which is convenient for people to go out or transfer and carry equipment.
