Description

Technical Field

[0001] This utility model relates to the field of walking aid technology, and in particular to a walking aid for nursing care. Background Technology

[0002] The elderly walking aid is a professional assistive device carefully designed for the elderly and people with mobility impairments. Its core purpose is to provide strong support and reliable stability when the user walks, thereby significantly reducing the possibility of falls during walking and adding a sense of safety and peace of mind to their daily activities. The walking aid mainly consists of a frame, casters, and a seat. When using it, the elderly person supports themselves with their hands on the frame, and then pushes the frame to walk slowly. When the elderly person needs to rest, the seat is flipped down, and the elderly person can sit on the seat after turning around once.

[0003] When elderly people need a short rest, they must first flip down the seat in front of them. Then, they must hold onto the support frame with both hands and turn around very slowly to sit on the seat for a short rest. Given that most elderly people have difficulty walking, there is a high risk of falling when turning around in the relatively narrow space of the support frame. This walking aid still has considerable room for improvement and optimization in terms of convenience. The design needs to be improved to better serve the elderly and reduce their potential dangers and inconveniences during use. Therefore, this application provides a nursing walking aid to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a nursing walking aid device to address the issue that the convenience of walking aids needs to be improved.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A nursing walking aid includes two supports, with a connecting rod fixed between them. Each support has a horizontal section one and a horizontal section two, with the horizontal section one located above the horizontal section two. Casters are fixed to the bottom of each support. The device also includes:

[0007] The support assembly includes a circular tube fixedly sleeved at two horizontal parts of the bracket. A cam is movably sleeved on the surface of the circular tube. A support plate is fixed on the surface of the cam. A horizontal support block is fixed on the surface of the circular tube. Two connecting plates are fixedly sleeved at the vertical part of the same bracket. A support rod is movably inserted through the top of the two connecting plates. The support rod abuts against the surface of the cam. A ring is fixedly sleeved on the surface of the support rod. The ring is located above the connecting plate. A spring is fixed between the bottom of the ring and the top of the upper connecting plate. A positioning hole is opened on the side of the cam.

[0008] When the elderly person sits on the support plate, the support plate is attached to the top of the horizontal support block, and the support rod moves along the side of the cam until it touches the ground. When the support plate is vertical, the support rod is inserted into the positioning hole.

[0009] Preferably, a triangular block is fixed to the surface of the cam, and the side of the triangular block is fixed to the bottom of the support plate.

[0010] Preferably, a support pad is fixed to the top of the support plate.

[0011] Preferably, the support pad is a rubber pad, and the top of the support pad has anti-slip stripes.

[0012] Preferably, a guide sleeve is movably fitted onto the surface of the support rod, and the guide sleeve is fixed between two connecting plates of the same bracket.

[0013] Preferably, the top of the support rod is hemispherical.

[0014] Preferably, a foot pad is fixed to the bottom of the support rod, and the top diameter of the foot pad is smaller than the bottom diameter of the foot pad.

[0015] Preferably, a limiting groove is formed on the surface of the circular tube, and a limiting block is fixed to the inner wall of the cam, with the limiting block slidably connected to the inner wall of the limiting groove.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, by setting up a support plate, when the elderly need to rest, they do not need to turn their bodies. They can simply flip the support plate downwards and sit down to rest by hand. When they get up, they can also simply flip the support plate back to its original position by hand. This greatly simplifies the operation process, makes it convenient for the elderly with mobility issues to use, effectively avoids the risk of falling due to turning, and improves the overall convenience of the walking aid device.

[0018] By incorporating a cam, positioning holes, and a support rod, when the support plate is rotated to the elderly person's seating position, the cam rotates on the circular tube during the rotation process. This causes the support rod to slide downwards along the side of the cam and support the ground. The foot pads increase the friction with the ground, effectively preventing the support from wobbling when the elderly person is resting. This provides stable and reliable support and ensures the safety of the elderly person while resting. When the support plate is vertical, the support rod will insert into the positioning hole to fix the support plate in place. No extra action is needed to lock the support plate, making operation more convenient.

[0019] By incorporating a support pad, the rubber support pad on top of the support plate is soft in texture, and its anti-slip stripes effectively increase the friction between the elderly and the support plate, preventing the elderly from slipping when seated, thus further improving the comfort and safety of the elderly when using the walking aid device.

[0020] By setting a limiting groove and a limiting block, and through the sliding connection between the limiting groove and the limiting block, the stability and accuracy of the cam's rotation on the round tube are ensured, so that the support plate can only rotate within a range of ninety degrees, making it more convenient to use.

[0021] By setting a guide sleeve, which movably engages with the support rod, the smooth sliding of the support rod is ensured, preventing the support rod from shifting. Attached Figure Description

Detailed Implementation

[0032] The following is a detailed description of a nursing walking aid device provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0033] like Figures 1-5 As shown, an embodiment of this utility model provides a nursing walking aid device, including two supports 1, a connecting rod 4 fixed between the two supports 1, and a horizontal part 1 2 and a horizontal part 2 3 provided on each of the two supports 1, with the horizontal part 1 2 located above the horizontal part 2 3. A caster wheel 5 is fixed to the bottom of the supports 1, and the device also includes:

[0034] Support assembly 6 includes a round tube 7 fixedly sleeved at the horizontal part 23 of bracket 1, a cam 8 movably sleeved on the surface of the round tube 7, a support plate 9 fixed on the surface of the cam 8, a horizontal support block 12 fixed on the surface of the round tube 7, two connecting plates 13 fixedly sleeved at the vertical part of the same bracket 1, a support rod 21 movably passing through the top of the two connecting plates 13, the support rod 21 abutting against the surface of the cam 8, a ring 15 fixedly sleeved on the surface of the support rod 21, the ring 15 being above the connecting plate 13, a spring 16 fixed between the bottom of the ring 15 and the top of the upper connecting plate 13, and a positioning hole 17 opened on the side of the cam 8;

[0035] When the elderly person sits on the support plate 9, the support plate 9 is attached to the top of the horizontal support block 12, the support rod 21 moves along the side of the cam 8, and finally the support rod 21 touches the ground. When the support plate 9 is vertical, the support rod 21 is inserted into the positioning hole 17.

[0036] like Figure 5 As shown, in this embodiment, a triangular block 11 is fixed to the surface of the cam 8, and the side of the triangular block 11 is fixed to the bottom of the support plate 9. The triangular block 11 strengthens the connection strength and stability between the cam 8 and the support plate 9, ensuring that the two can move closely and coordinately during the rotation of the support plate 9, accurately transmitting force and movement, preventing breakage between the cam 8 and the support plate 9 due to long-term use or large external force, ensuring the reliability and durability of the walking aid device's support and conversion functions, reducing safety hazards caused by component connection problems, and extending the device's service life.

[0037] like Figures 1-4As shown in this embodiment, a support pad 10 is fixed to the top of the support plate 9. When the elderly person sits on the support plate 9 to rest, it provides a buffer and support surface for direct contact with the body, which increases the comfort of the elderly person when resting and reduces local pressure on the body. In particular, it can effectively relieve fatigue for the elderly person who has been resting for a long time or whose body is relatively weak. At the same time, the presence of the support pad 10 also makes the contact between the elderly person and the support plate 9 softer, reducing the physical discomfort or skin damage that may be caused by hard contact.

[0038] like Figures 1-4 As shown, in this embodiment, the support pad 10 is a rubber pad with anti-slip stripes on the top. The rubber material has a certain elasticity and flexibility, and the anti-slip stripes increase the surface friction. The elasticity of the rubber pad further enhances comfort and can better adapt to changes in the body shape and movement of the elderly. The anti-slip stripes can effectively prevent the elderly from slipping on the support board 9 due to body movement or external shaking, enhancing safety during rest. In particular, for the elderly with limited mobility and poor balance, it greatly reduces the risk of accidental falls.

[0039] like Figures 1-4 As shown, in this embodiment, a guide sleeve 14 is movably sleeved on the surface of the support rod 21. The guide sleeve 14 is fixed between two connecting plates 13 of the same bracket 1. The guide sleeve 14 provides precise guidance and limitation for the movement of the support rod 21, so that it can only move smoothly between the connecting plates 13 along the set straight line direction. This ensures the accuracy and stability of the movement of the support rod 21 driven by the rotation of the cam 8, and avoids affecting the normal operation of the entire support assembly 6 due to the offset, shaking or jamming of the support rod 21. This helps to improve the reliability and response speed of the device, and ensures that the support structure can play a timely and accurate role when the elderly need to sit down or get up, reducing the probability of failure.

[0040] like Figure 4 As shown, in this embodiment, the top of the support rod 21 is hemispherical. The hemispherical top makes the support rod 21 more smoothly contact and slide relative to the side of the cam 8, reducing the frictional resistance and wear between the support rod 21 and the cam 8, improving the smoothness and flexibility of their movement. During long-term use, it can reduce the heat and component wear caused by friction, help maintain the stability of the device's performance, extend the service life of related components, and also make the movement transition of the entire support assembly 6 smoother, reducing the adverse effects on elderly users caused by jamming or sudden changes in resistance. It also allows the support rod 21 to be quickly inserted into the positioning hole 17.

[0041] like Figures 1-4As shown, in this embodiment, a foot pad 18 is fixed to the bottom of the support rod 21. The top diameter of the foot pad 18 is smaller than the bottom diameter of the foot pad 18. When the support rod 21 is supported on the ground, the foot pad 18 contacts the ground. Its special shape design increases the contact area and friction with the ground. The larger contact area can better disperse the pressure borne by the support rod 21, preventing the ground from being damaged or the support rod 21 from sinking into the ground due to pressure concentration. The increased friction can effectively prevent the bracket 1 from shaking or shifting due to insufficient ground friction when the elderly are resting. This significantly improves the stability and safety of the device in the supported state, providing a reliable rest support environment for the elderly.

[0042] like Figure 5 As shown, in this embodiment, a limiting groove 19 is formed on the surface of the circular tube 7, and a limiting block 20 is fixed to the inner wall of the cam 8. The limiting block 20 is slidably connected to the inner wall of the limiting groove 19, which precisely limits and guides the rotation of the cam 8 on the circular tube 7, restricting its rotation range and direction, and ensuring that the cam 8 can only rotate within a 90-degree angle range. This prevents structural damage or functional failure of the support component 6 due to excessive rotation or deviation from the normal track. This limiting design makes the working process of the entire walking aid device more standardized and predictable, improves the safety and reliability of the device, reduces the risk of safety accidents caused by accidental rotation, and also helps to extend the service life of each component and reduce maintenance costs.

[0043] Working principle: When the elderly need to sit down to rest, they do not need to turn their body. They can simply flip the support plate 9 downwards with their hands. Since the cam 8 is movably connected to the round tube 7, and the triangular block 11 fixes the support plate 9 to the cam 8, the support plate 9 drives the cam 8 to rotate on the round tube 7 during the downward flipping process. At this time, the support rod 21, which is fixedly connected between the two connecting plates 13 in the vertical part of the bracket 1, will move along the side of the cam 8. Due to the action of the spring 16, the support rod 21 will slide smoothly on the side of the cam 8. Finally, the support rod 21 will touch the ground, and the foot pad 18 will contact the ground. The top diameter of the foot pad 18 is smaller than the bottom diameter, which can increase the friction between the foot pad 18 and the ground, prevent the bracket 1 from shaking when the elderly sit on the support plate 9 to rest, and improve safety. At this time, the support plate 9 is attached to the top of the horizontal support block 12, providing stable support for the elderly.

[0044] When the elderly person finishes resting and gets up, they can directly flip the support plate 9 upwards with their hands. During this process, the cam 8 rotates in the opposite direction, and the support rod 21 moves upwards along the side of the cam 8. When the support plate 9 returns to the vertical position, the support rod 21 is inserted into the positioning hole 17 on the side of the cam 8 under the action of the spring 16 to support and fix the support plate 9 so that the walking aid device can be used normally in the future.

[0045] Throughout the process, the limiting groove 19 on the surface of the circular tube 7 is slidably connected to the limiting block 20 fixed on the inner wall of the cam 8, ensuring the stability and directionality of the cam 8 when rotating on the circular tube 7. At the same time, the rubber support pad 10 on the top of the support plate 9 has anti-slip stripes on its top, which can provide a comfortable and non-slip sitting surface for the elderly. In addition, the guide sleeve 14 that is movably sleeved on the surface of the support rod 21 is fixed between the two connecting plates 13 of the same bracket 1, which guides the movement of the support rod 21. The top of the support rod 21 is hemispherical, which facilitates its smooth sliding on the side of the cam 8.

[0046] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
