Description

Technical Field

[0001] This invention relates to the field of nursing equipment technology, specifically to an assistive standing and fall prevention device for elderly care. Background Technology

[0002] Elderly care is an important field of medical and social services. With the growth of the global aging population, there is increasing concern for the health and safety of the elderly. Older adults often face problems such as mobility impairment, muscle weakness, and decreased balance, which increase their risk of falls when standing and walking. Falls can lead to serious injuries and complications. To reduce the risk of falls in older adults, assistive fall prevention devices are needed to improve their leg mobility.

[0003] Existing fall prevention devices for elderly care always require the elderly to use their hands for support. After prolonged use, this can put a significant strain on the elderly's physical strength, leading to fatigue. Once fatigued, the fall prevention device loses its stability due to the loss of arm support, increasing the risk of falls and injuries. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an assistive standing and fall prevention device for elderly care, which solves the problems of poor protection and inability to provide fall prevention protection for the elderly from multiple directions.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an assistive standing and fall prevention device for elderly care, comprising tracks, movable blocks slidably connected to the top left and right sides of two tracks, a relay plate fixedly connected to the adjacent side of the two movable blocks, an embedded block fixedly connected to the bottom of each movable block, pulleys rotatably connected to the bottom left and right sides of each embedded block, positioning blocks fixedly connected to the adjacent side of each movable block, limit grooves formed on the upper and lower sides of the inner wall of each positioning block, protective plates slidably connected to the adjacent side of the inner walls of each positioning block, ropes fixedly connected to the distant side of each of the two protective plates, limit rings fixedly connected to the outer walls of each rope, springs provided on the distant side of each of the two protective plates, positioning rollers rotatably connected to the upper and lower sides of the inner walls of each movable block, mounting rings fixedly connected to the adjacent side of multiple ropes, vests rotatably connected to the inner walls of each mounting ring, speed sensors provided on the left and right sides of each vest, a positioning component installed on the top of the relay plate, and mounting components installed on the left and right sides of the tracks.

[0006] Preferably, the positioning component includes a motor, which is fixedly connected to the top of the relay plate. A first bevel gear is fixedly connected to the output end of the motor. A second bevel gear is rotatably connected to the top of the relay plate. A mating block is fixedly connected to the bottom of the relay plate. A lead screw is fixedly connected to the bottom of the second bevel gear. A push plate is threadedly connected to the outer wall of the lead screw. Through rods are fixedly connected to the left and right sides of the bottom of the push plate. Multiple locking slots are provided at the bottom of the track.

[0007] Preferably, the installation assembly includes a placement rod, which is fixedly connected to the left and right sides of the track. The placement rod has a first movement groove on both its upper and lower inner walls, and a second movement groove on both its left and right sides at the middle of its inner wall. Lifting columns are slidably connected to both the upper and lower sides of the placement rod. Passage grooves are formed on the near-diagonal sides of the two lifting columns. Toothed plates are fixedly connected to the near-diagonal sides of the two lifting columns. A transmission rod is rotatably connected to the middle of the inner wall of the placement rod. A drive gear is fixedly connected to the middle of the outer wall of the transmission rod. Rotary wheels are fixedly connected to the far sides of the two transmission rods. Rubber plates are fixedly connected to the far sides of the two lifting columns.

[0008] Preferably, the rope passes through the movable block and is movably connected to the adjacent side of the two positioning rollers, the spring is disposed on the distant side of the two movable blocks, and the protective plate is slidably connected to the inner wall of the limiting groove.

[0009] Preferably, the pulley is movably connected to the inner wall of the track, and the embedded block is slidably connected to the inner wall of the track.

[0010] Preferably, the push plate is slidably connected to the inner wall of the mating block, and the through rod passes through the mating block and is slidably connected to the inner wall of the locking groove.

[0011] Preferably, the first bevel gear and the second bevel gear are meshed, and the lead screw is rotatably connected to the bottom of the inner wall of the mating block.

[0012] Preferably, the toothed plate is slidably connected to the inner wall of the second motion groove, and the lifting column is slidably connected to the inner wall of the first motion groove.

[0013] Preferably, the toothed plate is slidably connected to the inner wall of the passage groove, and the toothed plate and the drive gear are meshed.

[0014] Preferably, the limiting ring is slidably connected to one side of the two moving blocks.

[0015] Working Principle: When using this assistive standing and fall prevention device, the operator first determines the installation location. Then, by rotating the wheel, the transmission rod is controlled to rotate the drive gear. During the rotation of the transmission rod, the drive gear and the toothed plate mesh synchronously, causing the toothed plates to move towards each other under the drive of the drive gear. This pushes the upper and lower lifting columns to connect the rubber plate with the wall and the ground. After adjustment, the damping device inside the wheel effectively prevents the wheel from reversing. This design effectively improves the adaptability of the device to different installation space heights and enhances the overall stability of the device during use through the contact between the rubber plate and the wall and the ground. Furthermore, due to the synchronous displacement of the two lifting columns, the track remains in the upper middle position, making it convenient for the elderly to wear the vest for use.

[0016] After installation, staff can have elderly individuals wear vests and perform standing or walking exercises. During standing, if an elderly person tilts forward or backward, the speed sensor immediately transmits the data to the PLC. If the forward / backward movement data exceeds a preset value, the PLC immediately controls the motors on both sides to drive them. The motors drive the first and second bevel gears to mesh, which in turn drives the lead screw to push multiple through-bars at the bottom of the push plate downwards via a threaded connection. This connects with the locking grooves at the bottom of the track, locking the moving block. This design effectively prevents the elderly person from tilting forward or backward. If the elderly person tilts left or right, a preset rope length pulls the protective plate to slide inside the positioning block, limiting the tilt to a certain angle and preventing them from falling to the ground. Furthermore, during use, the positioning component works in conjunction with the protective plate and other structures to provide multi-directional anti-tipping protection for the elderly person. With springs limiting the left and right range, the elderly person can move their upper limbs flexibly at a suitable tilt angle, improving the device's nursing functionality.

[0017] This invention provides an assistive standing and fall prevention device for elderly care. It has the following beneficial effects:

[0018] 1. This invention improves the fall prevention effect during elderly care assistance in standing and walking by using components such as positioning blocks, protective plates, ropes, vests, speed sensors, and positioning components. When the speed sensor detects that the forward and backward movement speed is too fast, the positioning components can be controlled to brake urgently to prevent the elderly from falling forward or backward and causing injury.

[0019] 2. This invention, through the combined use of components such as springs, positioning blocks, protective plates, limiting rings, and moving blocks, can prevent tipping during the lateral movement of elderly people during rehabilitation walking. At the same time, the range protection formed by the springs and protective plates allows the elderly to perform certain tilting movements during rehabilitation walking, thereby improving the flexibility of the elderly during use.

[0020] 3. The present invention, through the coordinated use of components such as the placement rod, lifting column, toothed plate, drive gear, rubber plate, and rotating wheel, can effectively improve the adaptability of the device when facing different floor heights. By rotating the turntable for adjustment, the track can always be positioned in the upper middle of the floor height, making it convenient for the elderly to wear and use after installation.

[0030] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example:

[0032] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 8 Appendix Figure 3 Appendix Figure 7 This invention provides an assistive standing and fall prevention device for elderly care, comprising a track 1, with movable blocks 2 slidably connected to the top left and right sides of two tracks 1, a relay plate 5 fixedly connected to the adjacent side of the two movable blocks 2, an embedded block 3 fixedly connected to the bottom of the movable blocks 2, pulleys 4 rotatably connected to the bottom left and right sides of the embedded block 3, a positioning block 6 fixedly connected to the adjacent side of the two movable blocks 2, a limit groove 7 formed on the upper and lower sides of the inner wall of the positioning block 6, a protective plate 8 slidably connected to the adjacent side of the inner wall of the two positioning blocks 6, a rope 9 fixedly connected to the outer wall of the two protective plates 8, a limit ring 10 fixedly connected to the outer wall of the rope 9, a spring 12 provided on the distant side of the two protective plates 8, a positioning roller 11 rotatably connected to the upper and lower sides of the inner wall of the movable blocks 2, and an installation ring 13 fixedly connected to the adjacent side of multiple ropes 9, a vest 14 rotatably connected to the inner wall of the installation ring 13. Through the rotatable connection between the vest 14 and the installation ring 13, the elderly can turn around and continue walking when walking to the edge of the track 1. Speed ​​sensors 15 are installed on both the left and right sides of vest 14, positioning components 16 are installed on the top of relay plate 5, and installation components 17 are installed on both the left and right sides of track 1.

[0033] When the elderly wear vest 14 and stand to use it, walking can pull the moving block 2 to move within the limits of track 1. The pulley 4 as an aid can effectively reduce the movement resistance of the moving block 2 and reduce the burden of walking for the elderly. The setting of spring 12 and protective plate 8 can improve the elderly's activity space during the anti-tipping process. When the elderly tilts to the left, the right protective plate 8 will gradually compress the spring 12 and contact the rear of the moving block 2 after sliding a certain space, effectively slowing down the speed of the overload of the tilt angle to the ground. The total length limitation of rope 9 and protective plate 8 can lock the elderly's position after tilting to a certain extent to prevent the elderly from falling to the ground. When the elderly are helped to stand up, spring 12 can push the protective plate 8 back to the original position to provide anti-tipping protection for subsequent use. During the tilting process, it can work in sync with positioning component 16 to complete the anti-tipping protection effect for the elderly from multiple angles.

[0034] Please see the appendix Figure 3 Appendix Figure 4 The positioning component 16 includes a motor 161, which is fixedly connected to the top of the relay plate 5. The output end of the motor 161 is fixedly connected to a first bevel gear 162. The top of the relay plate 5 is rotatably connected to a second bevel gear 163. The bottom of the relay plate 5 is fixedly connected to a mating block 168. The bottom of the second bevel gear 163 is fixedly connected to a lead screw 164. The outer wall of the lead screw 164 is threadedly connected to a push plate 167. The bottom left and right sides of the push plate 167 are fixedly connected to through rods 165. The bottom of the track 1 has multiple locking slots 166.

[0035] After the vest 14 is worn, the speed sensor 15 will transmit motion data to the PLC in real time. If the elderly person falls, the protective plate 8 will limit the tilt angle and exceed the PLC's preset motion speed value, thereby controlling the motor 161 to drive the lead screw 164 to rotate. This causes the push plate 167 to move downward during the threaded connection of the lead screw 164, thereby connecting the through rod 165 with the locking groove 166. This prevents the moving block 2 from moving and causing the elderly person to fall and touch the ground due to overload.

[0036] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 7The mounting assembly 17 includes a placement rod 171, which is fixedly connected to the left and right sides of the track 1. The inner wall of the placement rod 171 has a first movement groove 172 on both the upper and lower sides, and a second movement groove 173 on both the left and right sides of the middle of the inner wall of the placement rod 171. Lifting columns 174 are slidably connected to the upper and lower sides of the placement rod 171. Passing grooves 175 are opened on the near diagonal sides of the two lifting columns 174. Tooth plates 176 are fixedly connected to the near diagonal sides of the two lifting columns 174. A transmission rod 177 is rotatably connected to the middle of the inner wall of the placement rod 171. A drive gear 178 is fixedly connected to the middle of the outer wall of the transmission rod 177. A rotating wheel 1710 is fixedly connected to the far side of the two transmission rods 177. A rubber plate 179 is fixedly connected to the far side of the two lifting columns 174.

[0037] By rotating the damped wheel 1710, the connection between the drive gear 178 and the toothed plate 176 is controlled, so that the lifting columns 174 on both sides synchronously push the rubber plate 179 to contact the roof and ground of the installation floor, effectively improving the stability of the track 1 during use.

[0038] Please see the appendix Figure 5 - Appendix Figure 6 Rope 9 passes through the movable block 2 and is movably connected to the adjacent side of the two positioning rollers 11. Spring 12 is set on the distant side of the two movable blocks 2. Protective plate 8 is slidably connected to the inner wall of the limiting groove 7.

[0039] First, the position of the spring 12 is limited so that the spring 12 will not deform after exerting force on the protective plate 8. In the event of a tipping, the rope 9 passing through the moving block 2 can pull the protective plate 8 to exert a compressive force on the spring 12 under the spatial limitation of the limiting groove 7.

[0040] Please see the appendix Figure 3 The pulley 4 is movably connected to the inner wall of the track 1, and the embedded block 3 is slidably connected to the inner wall of the track 1.

[0041] The embedded block 3 can improve the stability of the moving block 2 during its movement on the top of the track 1, and the pulley 4 serves as an aid to reduce resistance during the movement of the elderly.

[0042] Please see the appendix Figure 3 - Appendix Figure 4 The push plate 167 is slidably connected to the inner wall of the mating block 168, and the through rod 165 passes through the mating block 168 and is slidably connected to the inner wall of the locking groove 166.

[0043] The position of the push plate 167 is limited so that the push plate 167 can change from rotation to up and down movement through the threaded connection of the lead screw 164, thereby pushing the through rod 165 to complete the position locking between the rod and the locking groove 166.

[0044] Please see the appendix Figure 6 Appendix Figure 3 Appendix Figure 4 The first bevel gear 162 and the second bevel gear 163 are meshed together, and the lead screw 164 is rotatably connected to the bottom of the inner wall of the mating block 168.

[0045] Through the meshing connection between the first bevel gear 162 and the second bevel gear 163, the power output of the motor 161 can be transmitted to the lead screw 164, and the lead screw 164 can rotate stably at the bottom of the mating block 168.

[0046] Please see the appendix Figure 7 Appendix Figure 1 The toothed plate 176 is slidably connected to the inner wall of the second motion groove 173, and the lifting column 174 is slidably connected to the inner wall of the first motion groove 172.

[0047] The movement trajectory of the toothed plate 176 is limited so that it can always be in contact with the drive gear 178 to achieve the meshing transmission effect, and the lifting column 174 is pushed synchronously to move inside the first motion groove 172.

[0048] Please see the appendix Figure 7 The toothed plate 176 is slidably connected to the inner wall of the through groove 175, and the toothed plate 176 and the drive gear 178 are meshed.

[0049] When the toothed plate 176 pulls the lifting column 174 to the closest position inside the placement rod 171, the slot 175 can provide a certain amount of moving space to the toothed plate 176 to prevent the movement of the toothed plate 176 from being restricted.

[0050] Please see the appendix Figure 3 Appendix Figure 5 The limiting ring 10 is slidably connected to the adjacent side of the two moving blocks 2. The limiting ring 10 reduces the noise generated when the spring 12 pushes the protection plate 8 to reset.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
