Description

Technical Field

[0001] This utility model relates to a walking aid, specifically a fall prevention walking aid for pregnant women, and belongs to the field of walking aid technology. Background Technology

[0002] During the second and third trimesters of pregnancy, as the fetus develops and the uterus enlarges, the abdomen gradually protrudes, causing a significant forward shift in the body's center of gravity. This leads to an increased lumbar lordosis, anterior pelvic tilt, and increased weight-bearing on the lower limbs. Walking becomes extremely challenging, as women are more prone to fatigue, instability, and decreased balance, significantly increasing the risk of falls and posing a serious threat to both the mother and fetus. Therefore, walking aids become essential assistive devices for pregnant women in the second and third trimesters, aiding in daily activities and exercise.

[0003] Several walking aids specifically designed for pregnant women have emerged in the prior art. For example, CN213346680U discloses a maternal medical assistive walking device for pregnant women, which includes a support frame A and a support frame B. A mounting sleeve and an adhesive sleeve are movably connected between the support frames. A fixing strap is fixedly connected inside the mounting sleeve to restrain the waist. A first seat, a second seat, and a third seat are fixedly connected to the upper surface of the support frames, allowing the pregnant woman to sit and rest when tired. The device secures the support frames by wrapping and adhesively attaching the fixing straps, preventing the device from tilting and causing accidents. Another example is CN210962932U, which discloses a walking aid for pregnant women, including a frame, four casters, a support component, a stool, and a strap assembly. The stool is detachably connected to the frame and has a storage position and an unfolded position. The waist strap of the strap assembly is connected to the frame to restrain the pregnant woman's waist. When in use, the pregnant woman is within the space formed by the frame, with her arms resting on the support frame and her hands gripping the handrails to propel herself forward. The frame provides support for the pregnant woman, and the waist strap prevents her from falling. However, while the existing walking aids mentioned above address the needs of pregnant women for support during walking and temporary rest to some extent, their functions remain relatively limited and cannot fully meet the diverse physiological characteristics and usage needs of pregnant women. On one hand, the seat structure in existing technologies only provides basic sitting and resting functions, but pregnant women lack sufficient support points when getting up or sitting down, making them prone to instability and falls. Furthermore, the seat height is often fixed or inconvenient to adjust, making it difficult to adapt to the different heights of pregnant women and the variations in body shape due to changes in gestational age. On the other hand, and more importantly, existing walking aids generally lack specific support structures for the protruding abdomen of pregnant women. During walking, the weight of the abdomen is entirely borne by the lumbar spine, pelvis, and lower limb muscles, resulting in a noticeable feeling of abdominal heaviness and continuous tension in the back muscles. Prolonged walking easily leads to fatigue and soreness. Existing technologies only use a waist belt for simple restraint, which only serves to prevent backward falls and cannot effectively support and reduce the pressure on the abdomen, thus failing to truly alleviate the physical burden on pregnant women. In addition, the existing walking aids have a relatively simple armrest height adjustment method, which makes it difficult to achieve coordinated adaptation with the seat height and the position of the belly support. This results in poor versatility of the walking aids at different stages of pregnancy and a limited usage period. Utility Model Content

[0004] This invention addresses the problem that existing walking aids have limited functionality, only assisting pregnant women in maintaining balance and walking through a support structure, thus failing to meet the diverse needs of pregnant women. Therefore, this invention provides a fall prevention walking aid for pregnant women.

[0005] The present invention achieves the above objectives through the following technical solution: it includes support legs, a reinforcing frame is fixedly connected between two support legs, a liftable handrail is fixedly connected to the surface of each support leg, and a handle is fixedly connected to the top of each liftable handrail.

[0006] Each adjustable armrest has a sleeve that slides onto its surface. Between the two sleeves is a seat unit for pregnant women to rest on. A belly support is installed on the upper side of the two support legs. The belly support is located behind the seat unit. An adjustment unit is installed between the belly support and the reinforcing frame to adjust the installation height of the belly support.

[0007] As a further improvement of this utility model: each support leg has a walking wheel rotatably connected to both ends via an axle, and two of the walking wheels are equipped with brakes.

[0008] As a further embodiment of this utility model: the seat plate unit includes a connecting block, a claw, a locking rod and a seat plate. Each sleeve has a connecting block symmetrically fixedly connected to both sides. Each connecting block has a claw fixedly connected to its side surface. Two locking rods are respectively locked into the claws at corresponding positions. The surfaces of the two locking rods are fixedly connected to the seat plate.

[0009] As a further improvement of this utility model: multiple adjustment holes are equally spaced on the surfaces of the sleeve and the adjustable handrail, and the sleeve is connected to the adjustable handrail through the cooperation of two fastening bolts and the adjustment holes.

[0010] As a further improvement of this utility model: L-shaped handrails are fixedly connected to the surfaces of the two connecting blocks on the same side, and anti-slip sleeves are fixedly fitted onto the surfaces of the L-shaped handrails.

[0011] As a further embodiment of this utility model: the adjustment unit includes an outer hollow column, a connecting horizontal plate, a gearbox, a screw, a first bevel gear, a second bevel gear, a control lever, and a movable column. The connecting horizontal plate is fixedly connected to the bottom surface of the support plate. The outer hollow column is fixedly connected between the connecting horizontal plate and the reinforcing frame. The gearbox is fixedly connected to the column body section of the outer hollow column. The screw is rotatably connected inside the gearbox. The top end of the screw penetrates the surface of the gearbox and extends to the inner side of the outer hollow column. A movable column is slidably connected to the inner side of the outer hollow column. The movable column is threaded onto the surface of the screw. The first bevel gear is fixedly sleeved on the body of the screw. The second bevel gear is meshed with the surface of the first bevel gear. A control lever is rotatably connected to the side surface of the gearbox. The control lever and the second bevel gear are fixedly connected.

[0012] As a further improvement of this utility model: positioning cylinders are fixedly connected to the surfaces of both support legs, and L-shaped inserts are fixedly connected to both sides of the support plate, with the L-shaped inserts slidably inserted into the positioning cylinders.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model effectively solves the problem that traditional walking aids for pregnant women can only assist walking but cannot provide temporary rest for pregnant women by setting sleeves and seat units on the height-adjustable armrests. The walking aid is equipped with a seat unit consisting of a connecting block, claws, a lever and a seat between the two sleeves. When pregnant women are tired from walking, they can sit down and rest directly without having to find a separate seat, which greatly improves the convenience and safety of use. The seat is engaged with the claws and levers, which is simple in structure, easy to assemble and disassemble, and has strong stability. It can meet the temporary sitting and resting needs of pregnant women, while not affecting the normal walking support function. It truly realizes the free switching between walking and resting, which significantly improves the comfort and practicality of pregnant women when going out and indoors, and reduces the risk of falls and overexertion caused by physical exhaustion.

[0015] 2. This utility model effectively solves the problems of abdominal sagging and excessive lumbar burden during walking by setting an abdominal support board and matching adjustment unit on the upper side of the support leg. It achieves flexible support and pressure relief protection for the abdomen. The abdominal support board is set on the rear side of the seat unit, which can conform to the shape of the pregnant woman's abdomen and provide even support for the protruding abdomen, relieving the pressure of the abdominal weight on the lumbar spine, pelvic floor muscles and lower limbs, and reducing walking fatigue. The adjustment unit adopts a purely mechanical structure such as an outer hollow column, gearbox, screw, bevel gear and moving column, which can continuously and accurately adjust the height of the abdominal support board to adapt to the abdominal position of pregnant women of different stages of pregnancy and different heights. The support force is moderate and the position is adjustable. The structure achieves a high degree of adaptation to the physiological characteristics of pregnant women, improving the safety and comfort during the walking process.

[0016] 3. This utility model, through the combination of a height-adjustable armrest, adjustment holes, and fastening bolts, achieves synchronous height adjustment of the armrest and seat unit, solving the problems of fixed height and poor adaptability in traditional walkers. Multiple sets of equally spaced adjustment holes are provided on both the height-adjustable armrest and the sleeve surface, and the fastening bolts ensure positioning and fixation. Pregnant women can flexibly adjust the armrest and seat height according to their height, arm length, and the size of their abdomen during pregnancy, ensuring comfortable upper limb support, stable sitting posture, and a reasonable abdominal support position. The height adjustment operation is simple and the locking is reliable, requiring no special tools. This allows the walker to adapt to different body shape changes before, during, and in late pregnancy, extending its service life and improving the product's versatility and economy.

[0017] 4. This utility model significantly improves the mobility and stability of the walker by installing braked wheels at the bottom of the support legs, along with L-shaped handrails and anti-slip sleeves. This achieves a fall-prevention and easy-to-control effect. Wheels are installed at both ends of the support legs, making it easy for pregnant women to push and move, reducing walking resistance. Two of the wheels have built-in brakes, allowing for quick braking when the pregnant woman sits or stops, preventing accidental slippage and tipping over, thus greatly improving safety. The connecting block has L-shaped handrails with anti-slip sleeves, providing multi-point support for the pregnant woman when getting up, sitting down, and walking, increasing grip friction and preventing hand slippage. The combined effect of these multiple structures effectively reduces the risk of falls due to instability or exhaustion, ensuring safe movement.

[0018] 5. This utility model improves overall rigidity and stability by fixing a reinforced frame between the two support legs, preventing deformation and shaking during use. L-shaped inserts on both sides of the abdominal support board slide and engage with positioning cylinders on the support legs, guiding and limiting the lifting and lowering of the abdominal support board, ensuring it remains horizontally stable during adjustment without deviation or tilting. The adjustment unit uses gear and screw transmission, resulting in a compact structure, smooth transmission, and good self-locking. The abdominal support height is precisely adjusted and not easily loosened. The overall structural design is reasonable, with uniform force distribution, enabling long-term stable use and meeting the requirements of pregnant women for safe, reliable, and durable walking aids.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figures 1 to 8 As shown, a fall prevention walking aid for pregnant women includes support legs 1, a reinforcing frame 3 fixedly connected between two support legs 1, a height-adjustable handrail 4 fixedly connected to the surface of each support leg 1, and a handle 5 fixedly connected to the top of each height-adjustable handrail 4.

[0031] Each adjustable armrest 4 has a sleeve 6 slidably fitted onto its surface. A seat unit for pregnant women to rest is provided between two sleeves 6. A belly support board 7 is provided on the upper side of the two support legs 1. The belly support board 7 is located on the rear side of the seat unit. An adjustment unit is provided between the belly support board 7 and the reinforcing frame 3 to adjust the installation height of the belly support board 7.

[0032] When using this utility model, the handles 5 at the top of the adjustable armrest 4 are held with both hands, and a stable support structure is formed by the two support legs 1. The reinforced frame 3 firmly connects the two support legs 1 to improve the overall stability. The adjustable armrest 4 can be adjusted according to the height of the pregnant woman. The sleeve 6 slides along the adjustable armrest 4 to adjust the seat plate unit to a suitable resting height. The abdominal support board 7 is placed under the pregnant woman's abdomen. The installation height of the abdominal support board 7 can be changed by adjusting the unit to adapt to the abdominal height of different stages of pregnancy.

[0033] This new type of walker can simultaneously provide walking support, temporary rest, and abdominal pressure relief, solving the problem of the single function of traditional walkers. The reinforced frame 3 greatly improves the overall rigidity of the walker and prevents swaying and tipping. The height-adjustable handrail 4 works in conjunction with the abdominal support board 7 to accommodate pregnant women of different heights and gestational weeks, making it more widely applicable. It reduces the risk of falls and physical burden on pregnant women from both walking support and abdominal support aspects.

[0034] It should be noted that the liftable handrail 4 consists of an inner rod and an outer cylinder. The inner rod is slidably inserted into the outer cylinder, and the two are fixed in position by bolts, which is a common existing lifting structure.

[0035] Furthermore, each support leg 1 has a walking wheel 2 rotatably connected to both ends via an axle, and two of the walking wheels 2 are equipped with brakes.

[0036] When in use, the walking wheels 2 at both ends of the support leg 1 touch the ground, and the pregnant woman can easily push the walker to move. When she needs to stop to rest or fix a position, she can step on the walking wheel 2 with its own brake function to lock the wheel and prevent the walker from sliding.

[0037] The walking wheels 2 significantly reduce the physical exertion required for pregnant women to push the walker, making movement easier and less strenuous. The walking wheels 2 with brake function can quickly fix the position of the walker, preventing it from slipping when the pregnant woman sits or supports her belly, effectively improving safety. It protects the pregnant woman's fall prevention needs from both movement and fixation aspects, and is simple and convenient to use.

[0038] Furthermore, the seat plate unit includes a connecting block 61, a claw 63, a locking rod 64, and a seat plate 65. Each sleeve 6 has a connecting block 61 symmetrically fixedly connected to both sides. Each connecting block 61 has a claw 63 fixedly connected to its side surface. Two locking rods 64 are respectively locked into the claws 63 at corresponding positions. The surfaces of the two locking rods 64 are fixedly connected to the seat plate 65.

[0039] The connecting blocks 61 on both sides of the sleeve 6 provide an installation base for the seat plate unit. The claws 63 are fixed on the connecting blocks 61. The seat plate 65 is directly snapped into the claws 63 by the bottom clip rod 64 to complete the installation. When pregnant women are tired from walking, they can sit directly on the seat plate 65 to rest. The usage state can be switched without disassembly.

[0040] The snap-fit ​​design of the claw 63 and the lever 64 allows for quick assembly and disassembly of the seat 65, making it convenient to use and meeting the needs of pregnant women to rest at any time. This solves the problem of traditional walkers lacking a rest structure. The seat 65 stably supports the weight of the pregnant woman and, together with the support structure, forms a safe sitting space, preventing the pregnant woman from falling due to exhaustion and improving the practicality and comfort of the walker.

[0041] Furthermore, multiple adjustment holes 67 are equally spaced on the surfaces of the sleeve 6 and the adjustable handrail 4. The sleeve 6 is connected to the adjustable handrail 4 through the cooperation of two fastening bolts 62 and the adjustment holes 67.

[0042] During use, the sleeve 6 can be slid up and down along the adjustable handrail 4 according to the height of the pregnant woman and her usage needs. Align the sleeve 6 with the corresponding adjustment holes 67 on the adjustable handrail 4, insert the fastening bolt 62 and tighten it to complete the height fixation of the sleeve 6 and the seat plate unit.

[0043] The adjustment hole 67 and the fastening bolt 62 work together to achieve multi-level precise adjustment of the seat plate unit height, which can be adapted to pregnant women of different heights and body types. The fastening connection is firm and reliable, with no risk of loosening or shaking, ensuring the safety of the seat plate 65. The height-adjustable structure allows the walker to adapt to the changes in the pregnant woman's body shape throughout the entire pregnancy, extending the service life and improving the versatility of the device.

[0044] Furthermore, L-shaped handrails 66 are fixedly connected to the surfaces of the two connecting blocks 61 on the same side, and anti-slip sleeves are fixedly fitted on the surfaces of the L-shaped handrails 66.

[0045] When in use, pregnant women can hold the L-shaped handrail 66 on the connecting block 61 when getting up, sitting down, or walking. The anti-slip sleeve on the surface of the L-shaped handrail 66 increases the friction of the hand and provides additional support points.

[0046] The L-shaped armrests provide multiple points of support for pregnant women, compensating for the lack of single support from the top handles and reducing the probability of falls when standing up or sitting down. The anti-slip sleeves effectively prevent hand slippage and improve grip stability. The L-shaped structure conforms to human grip habits, resulting in more reasonable force distribution and further enhancing the walker's anti-fall function, making it safer and more comfortable to use.

[0047] Example 2

[0048] Improvements based on Example 1:

[0049] Furthermore, the adjustment unit includes an outer hollow column 73, a connecting horizontal plate 74, a gearbox 75, a screw 76, a first bevel gear 77, a second bevel gear 78, a control lever 79, and a moving column 710. The connecting horizontal plate 74 is fixedly connected to the bottom surface of the support plate 7. The outer hollow column 73 is fixedly connected between the connecting horizontal plate 74 and the reinforcing frame 3. The gearbox 75 is fixedly connected to the column section of the outer hollow column 73. The screw 76 is rotatably connected inside the gearbox 75. The top end of the screw 76 penetrates the surface of the gearbox 75 and extends to the inner side of the outer hollow column 73. The moving column 710 is slidably connected to the inner side of the outer hollow column 73. The moving column 710 is threaded onto the surface of the screw 76. The first bevel gear 77 is fixedly sleeved on the shaft of the screw 76. The second bevel gear 78 is meshed with the surface of the first bevel gear 77. The control lever 79 is rotatably connected to the side surface of the gearbox 75. The control lever 79 and the second bevel gear 78 are fixedly connected.

[0050] When the height of the belly support plate 7 needs to be adjusted, the control lever 79 on the outside of the gearbox 75 is rotated to drive the second bevel gear 78 to rotate. The second bevel gear 78 meshes with and drives the first bevel gear 77 and the screw 76 to rotate. The screw 76 drives the moving column 710 to move up and down in the outer hollow column 73. The belly support plate 7 is pushed up and down through the connecting horizontal plate 74 to achieve precise adjustment of the belly support height.

[0051] The bevel gear and screw 76 transmission structure ensures smooth, precise, and seamless height adjustment of the abdominal support plate 7, with strong self-locking properties and no slippage after adjustment. The control lever 79 is easy to operate, allowing pregnant women to adjust it independently. The outer hollow column 73 and the movable column 710 work together to provide high support strength, stably supporting the weight of the abdomen, effectively relieving the feeling of heaviness in the abdomen and pressure on the waist, and improving the comfort of walking.

[0052] It should be noted that both the outer hollow column 73 and the moving column 710 of the adjustment unit adopt an anti-deflection guide structure design. The cross-section of the moving column 710 is rectangular, and the interior of the outer hollow column 73 has a rectangular sliding groove that matches the outer dimensions of the moving column 710. The moving column 710 is slidably fitted within this sliding groove. During the rotation of the screw 76, the rectangular-section moving column 710, under the limiting action of the rectangular sliding groove of the outer hollow column 73, can only move in a straight vertical direction, effectively limiting the circumferential deflection and radial sway of the moving column 710. This ensures that the screw 76 will not cause the moving column 710 to rotate, deviate, or tilt when rotating, making the height adjustment process of the support plate 7 more stable, precise, and reliable, while improving the structural stability and stress safety of the support plate.

[0053] Furthermore, positioning cylinders 71 are fixedly connected to the surfaces of both support legs 1, and L-shaped inserts 72 are fixedly connected to both sides of the support plate 7. The L-shaped inserts 72 are slidably inserted into the positioning cylinders 71.

[0054] The L-shaped inserts 72 on both sides of the abdominal support plate 7 rise and fall with the abdominal support plate 7, and slide up and down in the positioning cylinder 71 on the support leg 1 to limit and guide the movement trajectory of the abdominal support plate 7.

[0055] The L-shaped insert 72 slides with the positioning cylinder 71 to ensure that the abdominal support plate 7 does not shift or tilt during the lifting and lowering process, and always maintains a horizontal and stable abdominal support state; the positioning guide structure improves the support stability of the abdominal support plate 7, avoids shaking that may cause abdominal discomfort to the pregnant woman, further enhances the overall structural reliability of the walking aid, and ensures the stable performance of the abdominal support function.

[0056] It should be noted that the abdominal support plate 7 adopts a quick-release and detachable structural design. The movable column 710 in the adjustment unit can be completely removed axially from the rectangular sliding groove inside the outer hollow column 73. At the same time, the L-shaped inserts 72 on both sides of the abdominal support plate 7 can be smoothly pulled out vertically upward from the positioning cylinders 71 fixed on the support legs 1. In use, the movable column 710 cooperates with the outer hollow column 73, and the L-shaped inserts 72 cooperate with the positioning cylinders 71 to achieve stable support and height adjustment of the abdominal support plate 7. When the pregnant woman does not need the abdominal support function, or needs to store or clean the equipment, the movable column 710 can be pulled out from the outer hollow column 73, and the L-shaped inserts 72 can be pulled out from the positioning cylinders 71, allowing the entire abdominal support plate 7 to be quickly separated from the main body of the walker, achieving free assembly and disassembly. This structure not only ensures the stability and safety of the abdominal support, but also allows for flexible selection of whether to install the abdominal support plate 7 according to the actual needs of the pregnant woman, changes in gestational age, and the needs of the scenario, improving the flexibility and versatility of the walker.

[0057] Working principle: Before using the walking aid, pregnant women should first make overall adjustments according to their height, gestational age and abdominal size. First, adjust the height of the adjustable handrails 4 on both sides of the support legs 1, and adjust the height of the handrails to a position where the arms hang naturally and can be held comfortably. Grip the handles 5 firmly to maintain a stable standing posture.

[0058] Then, adjust the height of the sleeve 6 on the adjustable armrest 4, slide the sleeve 6 up and down along the armrest, align the sleeve 6 with the corresponding adjustment hole 67 on the adjustable armrest 4, insert the fastening bolt 62 and tighten it to fix it, so that the seat plate unit is at a comfortable sitting height. After the height adjustment is completed, insert the locking rod 64 at the bottom of the seat plate 65 into the locking claw 63 on the connecting block 61 to complete the quick installation of the seat plate 65, so that pregnant women can rest at any time.

[0059] Next, adjust the abdominal support structure, rotate the control lever 79 on the outside of the gearbox 75, and drive the first bevel gear 77 and screw 76 to rotate through the second bevel gear 78, driving the moving column 710 to rise and fall in the outer hollow column 73, so that the abdominal support plate 7 fits against the lower abdomen of the pregnant woman, and the L-shaped inserts 72 on both sides of the abdominal support plate 7 slide synchronously in the positioning cylinder 71 to ensure that the abdominal support plate 7 is horizontal and stable.

[0060] When in use, the pregnant woman holds the handles 5 with both hands and walks with the help of the stable frame formed by the support legs 1 and the reinforced frame 3. The walking wheels 2 at the bottom of the support legs 1 can roll easily, reducing walking resistance. When she needs to stop or sit down to rest, she steps on the walking wheels 2 with brakes to completely fix the walker in place, and can then sit comfortably on the seat 65 to rest. When getting up or sitting down, she can hold the L-shaped armrests 66 and use the anti-slip sleeves to increase friction and achieve stable support. After use, she can release the claws 63 and the lever 64 to remove the seat 65, loosen the fastening bolts 62, and retract the sleeve 6 to complete the storage.

[0061] This walking aid has the advantages of assisting walking, preventing falls, allowing for sitting and resting, adjustable height, and providing abdominal support and pressure relief. It comprehensively solves the problems of traditional pregnant women's walking aids having limited functions, lacking a resting seat, and lacking an abdominal support structure. The walking wheels with brakes ensure both ease of movement and safety of use. The brakes are fast and reliable, preventing the device from slipping and causing accidents.

[0062] The height-adjustable armrest 4, in conjunction with the multi-level adjustment holes 67 and fastening bolts 62, allows for free height adjustment of the armrest and seat 65, accommodating pregnant women of different heights and gestational stages, making it suitable for use throughout pregnancy and extending the product's lifespan. The seat unit adopts a quick-installation structure with claws 63 and levers 64, requiring no tools for installation and removal, making operation simple and convenient, meeting the needs of pregnant women to rest at any time, and effectively relieving walking fatigue.

[0063] The maternity support board 7, equipped with an adjustment unit, allows for precise and stable height adjustment, effectively supporting the weight of the abdomen, reducing pressure on the lumbar spine and lower limbs, and alleviating the feeling of abdominal heaviness. The guiding structure of the L-shaped insert 72 and positioning cylinder 71 ensures stability and prevents wobbling during support, enhancing user comfort. The L-shaped armrest 66 and anti-slip sleeve provide multi-point auxiliary support for pregnant women when getting up and sitting down, further improving safety. The overall structure is scientifically designed, with reasonable force distribution and simple operation, truly meeting the needs of pregnant women for safe, comfortable, and convenient movement.
