Description

Technical Field

[0001] This invention relates to the field of walking aids, and more specifically to a multifunctional walking aid. Background Technology

[0002] For some patients who have difficulty getting out of bed, a small table is usually placed on the bed when they eat. The legs of the small table are placed on either side of the patient's thighs, and then the tableware and food are placed on the small table so that the patient can sit in bed to eat.

[0003] With the development of the concept of enhanced recovery after surgery (ERAS), it is advocated that postoperative patients get out of bed and move around as soon as possible to restore their ability to live independently and reduce postoperative complications. In particular, walking after meals has a great promoting effect on rehabilitation, which can further promote digestion and accelerate the recovery process. In order to facilitate patients' use of force, walking aids are usually used for support. Walking aids are assistive tools that support walking and are widely used in clinical practice for postoperative patients to help them walk independently, improve their ability to walk independently, reduce pain, and accelerate the recovery of walking function.

[0004] However, if a small dining table and a walking aid are placed in the ward at the same time, it will reduce the patient's activity space due to the limited space in the ward. Therefore, in order to reduce the space occupied in the ward, there is an urgent need for a multifunctional walking aid that can both allow patients to eat in bed and help them get out of bed. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is: in order to reduce the space occupied in the ward, there is an urgent need for a multifunctional walking aid that can both allow patients to eat in bed and help them get out of bed.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multifunctional walking aid, comprising: a dining board and a walking frame; the walking frame is respectively installed on both sides of the dining board in the length direction; each walking frame includes a support leg and a handrail; there are two support legs, each support leg including a connecting section, a telescopic section, a bending section, and a limiting mechanism; one end of the telescopic section is slidably installed in the connecting section, the connecting section is installed on the dining board, and the other end of the telescopic section is provided with a bending groove; one end of the bending section is located in the bending groove, the bending section is hinged to the telescopic section, and the bending section cooperates with the bending groove; the bending section can be limited by the limiting mechanism to restrict the sliding of the telescopic section on the connecting section; the handrail is installed on the two connecting sections. By incorporating the function of a dining table into the walking aid, the walking aid and the dining table are integrated into one unit, thereby effectively reducing the floor space occupied.

[0007] Preferably, the limiting mechanism includes a torsion spring, a pushing block, a locking block, and a driving assembly; the torsion spring is installed at the hinge of the bending section and the telescopic section, and the torsion spring applies a torque to the bending section away from the bending groove; a sliding groove is provided in the length direction of the telescopic section, the pushing block is slidably installed in the sliding groove, and the end of the pushing block away from the torsion spring is provided with a pushing inclined surface; the locking block is arranged perpendicular to the pushing block, and the locking block slides through the telescopic section, the end of the locking block near the pushing block is provided with a pushed inclined surface, and the end of the locking block near the pushing block extends into the sliding groove, the pushed inclined surface and the pushing inclined surface are arranged parallel to each other; a locking groove is provided on the connecting section, and the side of the locking block away from the pushing block abuts against the locking groove; the bending section controls the sliding of the pushing block through the driving assembly. The bending section controls the movement of the jacking block through the drive mechanism. The jacking block slides away from the locking block, causing the jacking inclined surface of the jacking block to separate from the jacking inclined surface. The end of the jacking block away from the jacking inclined surface disengages from the slot on the connecting section and slides into the telescopic section, thereby stopping the limiting between the telescopic section and the connecting section, allowing the telescopic section to slide within the connecting section.

[0008] Preferably, the drive assembly includes a pull rope, a roller, and a spring; the roller is installed at the hinge of the bending section and the telescopic section, and the roller is fixedly connected to the bending section; one end of the pull rope is installed on the bending section, and the other end of the pull rope passes around the roller near the side of the bending section and is installed on the push block; the spring is installed in a groove, the spring is located at the end of the push block near the pull rope, one end of the spring abuts against the push block, and the other end of the spring abuts against the inner wall of the telescopic section. When the patient needs to eat, the bending section is rotated, and the bending section causes the pull rope to wrap around the roller, thereby pulling the push block to slide, while compressing and storing force on the spring. Conversely, when the patient needs to get out of bed, the bending section is rotated in the opposite direction, the pull rope extends, and the spring pushes the push block to push the locking block.

[0009] Preferably, the drive assembly further includes a reel, a first gear, and a second gear; one end of the pull rope is mounted on the bending section via the reel, and the reel is rotatably mounted on the bending section; the first gear is coaxially fixed to the roller, and the second gear is coaxially fixed to the reel, with the first and second gear meshing with each other. The bending section drives the second gear to rotate around the first gear, causing the first gear to drive the second gear to rotate, which in turn drives the reel to rotate. This allows the pull rope to not only wrap around the roller in a small section but also around the reel, enabling the pull rope to move the pushing block a greater distance, facilitating the pushing of the locking block.

[0010] Preferably, each of the walking aids is mounted on the table via one of the connecting segments, the connecting segments being rotatably mounted on the table; it also includes an adjustment mechanism that can adjust the angle of rotation of the connecting segments. By adjusting the angle of the connecting segments on the table via the adjustment mechanism, the angle of the walking aid can be adjusted, thereby adjusting the height of the table, and when the walking aid is tilted toward the opposite sides of the table, the stability of the support for the table can be improved.

[0011] Preferably, the adjustment mechanism includes a rotating shaft and two adjustment components; each adjustment component corresponds to a walking frame and includes a connecting sleeve, a threaded rod, and a sliding head; one end of the connecting sleeve is rotatably fitted onto the connecting section mounted on the table board, and the other end of the connecting sleeve is rotatably connected to the rotating shaft; the sliding head is slidably installed inside the connecting sleeve along its length; one end of the threaded rod is fixedly connected to the rotating shaft, and the other end of the threaded rod is located inside the connecting sleeve, and the other end of the threaded rod is threadedly connected to one end of the sliding head. The rotating shaft drives the threaded rod to rotate, and the threaded rod drives the sliding head to slide towards the connecting section inside the connecting sleeve, so that the sliding head abuts against the connecting section. After the angle of the connecting section is adjusted, the connecting section is fixed by the friction between the sliding head and the connecting section, thereby completing the angle adjustment of the walking frame.

[0012] Preferably, a limiting component is installed at one end of the sliding head near the connecting section; the limiting component includes an elastic plate, hooks, and abutments; the connecting section has multiple grooves arranged in a circular array around the axis of the connecting section, and each groove has protruding edges on opposite sides; both ends of the elastic plate are hinged to the abutments; an abutment is fixedly installed at the middle of the side of the elastic plate near the connecting section; multiple hooks are fixedly installed on the side of the elastic plate near the connecting section, and the hooks face the abutments. This limits the movement of the connecting section, thereby preventing it from rotating in either direction.

[0013] Preferably, it further includes a synchronization mechanism, which comprises a transmission gear and a reversing gear; the transmission gear corresponds one-to-one with the walking aid, and the transmission gear rotates synchronously with the connecting section rotatably mounted on the table; both the transmission gear and the reversing gear are rotatably mounted on the table; and the reversing gear meshes with two of the transmission gears. This ensures that when one walking aid is rotated, the other walking aid rotates synchronously in the opposite direction, thereby increasing the adjustment speed of the walking aid.

[0014] Preferably, the transmission gear rotates synchronously with the connecting section via a transmission assembly; the transmission assembly includes a first sprocket, a second sprocket, and a chain; the first sprocket is coaxially fixed to the connecting section, the second sprocket is coaxially fixed to the transmission gear, and the first sprocket is connected to the second sprocket via the chain. The connecting section drives the first sprocket to rotate, the first sprocket drives the second sprocket to rotate via the chain, and the second sprocket drives the transmission gear to rotate; this enables long-distance transmission and reduces the diameter of the gear.

[0015] Preferably, the armrests are fitted with soft padding. The soft padding improves patient comfort.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] By incorporating a dining table function into the walker, the invention effectively reduces the floor space required for meals. In this invention, when the patient needs to eat, the bending section is rotated, engaging the bending groove. As the bending section rotates, a limiting mechanism is activated, separating the telescopic section from the connecting section. After the bending section is engaged in the bending groove, the telescopic section slides, allowing both the telescopic and bending sections to slide entirely into the connecting section, thus shortening the leg length for easier placement on the bed. Finally, the two shortened walkers are placed on either side of the patient's thighs, supporting the dining table for meals. When the patient needs to get out of bed, the telescopic and bending sections slide out of the connecting section, and the bending section is rotated in the opposite direction, aligning the bending, telescopic, and connecting sections in a straight line. During the rotation of the bending section, the slid-out telescopic section is limited, thus securing it in place. Attached Figure Description

Detailed Implementation

[0029] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0030] In this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] See Figures 1-3 The present invention provides an embodiment of a multifunctional walking aid, comprising: a tray 1 and a walking frame; the tray 1 has walking frames mounted on both sides along its length; each walking frame includes a support leg and a handrail 2; the support leg has two legs, each leg including a connecting section 3, a telescopic section 4, a bending section 5, and a limiting mechanism 6; one end of the telescopic section 4 is slidably mounted in the connecting section 3, the connecting section 3 being mounted on the tray 1, and the other end of the telescopic section 4 having a bending groove 42; one end of the bending section 5 is located in the bending groove 42, and the bending section 5 is hinged to the telescopic section 4, and the bending section 5 cooperates with the bending groove 42; the bending section 5 can restrict the sliding of the telescopic section 4 on the connecting section 3 by the limiting mechanism 6; the handrail 2 is mounted on the two connecting sections 3; furthermore, a soft pad 21 is mounted on the handrail 2; specifically, the soft pad 21 can be made of rubber, which improves the patient's comfort.

[0033] Specifically, when the patient needs to eat, the bending section 5 is rotated, causing it to engage with the bending groove 42. As the bending section 5 rotates, it controls the limiting mechanism 6, which separates the telescopic section 4 from the connecting section 3. After the bending section 5 bends and engages with the bending groove 42, the telescopic section 4 slides, allowing both the telescopic section 4 and the bending section 5 to slide completely into the connecting section 3. This shortens the length of the support leg, making it easier to place on the bed. Finally, the two shortened walking frames are placed on either side of the patient's thighs, supporting the dining board 1 for eating. When the patient needs to get out of bed, the telescopic section 4 and the bending section 5 slide out of the connecting section 3, and the bending section 5 is rotated in the opposite direction, aligning the bending section 5, the telescopic section 4, and the connecting section 3 in a straight line. During the rotation of the bending section 5, the sliding telescopic section 4 is limited, thus securing it in place. By incorporating a dining table into the walker, the walker combines the functions of a walking aid and a dining table, thus effectively reducing the floor space required.

[0034] See Figures 1-5In other embodiments, the limiting mechanism 6 includes a torsion spring, a pushing block 61, a locking block 62, and a driving assembly. The torsion spring is installed at the hinge of the bending section 5 and the telescopic section 4, and applies a torque to the bending section 5 away from the bending groove 42. Specifically, the torsion spring is sleeved at the hinge of the bending section 5 and the telescopic section 4, with one end of the torsion spring fixedly connected to the bending section 5 and the other end fixedly connected to the telescopic section 4. When the bending section 5 rotates into the bending groove 42, the bending section 5 compresses and stores force on the torsion spring. When released, the torsion spring drives the bending section 5 to rotate outward from the bending groove 42. When the bending section 5 is parallel to and abuts against the telescopic section 4, the torsion spring applies a torque to the bending section 5 away from the bending groove 42. Pre-tension is applied to prevent spontaneous rotation of the bending section 5; a groove 41 is provided along the length of the telescopic section 4, and the push block 61 is slidably installed in the groove 41, with a push inclined surface at the end of the push block 61 away from the torsion spring; the snap-fit ​​block 62 is perpendicular to the push block 61 and slides through the telescopic section 4, with a push inclined surface at the end of the snap-fit ​​block 62 near the push block 61, and the push inclined surface and the push inclined surface are parallel to each other; a slot is provided on the connecting section 3, and the side of the snap-fit ​​block 62 away from the push block 61 abuts against the slot; the bending section 5 controls the sliding of the push block 61 through the drive assembly.

[0035] When the patient needs to eat, the bending section 5 is rotated, and the bending section 5 controls the push block 61 to move through the drive mechanism. The push block 61 slides away from the locking block 62, causing the pushing slope of the push block 61 to separate from the pushed slope of the push block 61. The end of the push block 61 away from the pushed slope disengages from the slot on the connecting section 3 and slides into the telescopic section 4, thereby stopping the limitation between the telescopic section 4 and the connecting section 3, allowing the telescopic section 4 to slide within the connecting section 3. Conversely, when the patient needs to get out of bed, the bending section 5 is rotated in the opposite direction, and the bending section 5 controls the push block 61 to slide towards the locking block 62 through the drive mechanism. The push block 61 pushes the pushed slope of the push block 61 through the pushing slope, locking the end of the push block 61 away from the pushed slope into the slot on the connecting section 3, thereby restricting the telescopic section 4 from sliding within the connecting section 3.

[0036] See Figures 1-5In other embodiments, the drive assembly includes a pull rope 63, a roller 64, and a spring 65; the roller 64 is installed at the hinge of the bending section 5 and the telescopic section 4, and the roller 64 is fixedly connected to the bending section 5; one end of the pull rope 63 is installed on the bending section 5, and the other end of the pull rope 63 passes around the roller 64 and is installed on the push block 61 near the side of the bending section 5; the spring 65 is installed in the slide groove 41, the spring 65 is located at the end of the push block 61 near the pull rope 63, and one end of the spring 65 abuts against the push block 61, and the other end of the spring 65 abuts against the inner sidewall of the telescopic section 4. When the patient needs to eat, the bending section 5 is rotated, and the bending section 5 causes the pull rope 63 to wrap around the roller 64, thereby pulling the push block 61 to slide through the pull rope 63, while compressing and storing the spring 65. Conversely, when the patient needs to get out of bed, the bending section 5 is rotated in the opposite direction, the pull rope 63 extends, and the spring 65 pushes the push block 61 to push the locking block 62.

[0037] See Figures 1-5 In other embodiments, the drive assembly further includes a spool 66, a first gear 67, and a second gear 68. One end of the pull rope 63 is mounted on the bending section 5 via the spool 66, and the spool 66 is rotatably mounted on the bending section 5. The first gear 67 is coaxially fixed to the roller 64, and the second gear 68 is coaxially fixed to the spool 66, with the first gear 67 and the second gear 68 meshing with each other. In specific implementation, rotating the bending section 5 causes the second gear 68 to rotate around the first gear 67, which in turn causes the first gear 67 to rotate, and the second gear 68 to rotate the spool 66. This allows the pull rope 63 to not only wrap a small portion around the roller 64, but also to wrap around the spool 66, enabling the pull rope 63 to move the pushing block 61 a greater distance, thus facilitating the pushing of the locking block 62.

[0038] See Figures 1-8 In other embodiments, each walking aid is mounted on the table board 1 via one of the connecting segments 3, and the connecting segments 3 are rotatably mounted on the table board 1. An adjustment mechanism 7 is also included, which can adjust the angle of rotation of the connecting segments 3. Specifically, by adjusting the angle of the connecting segments 3 on the table board 1 through the adjustment mechanism 7, the angle of the walking aid can be adjusted, thereby adjusting the height of the table board 1. Furthermore, when the walking aid is tilted towards either side of the table board 1, the stability of the support for the table board 1 can be improved.

[0039] See Figures 1-8In other embodiments, the adjustment mechanism 7 includes a rotating shaft 71 and two adjustment components; each adjustment component corresponds to a walking frame and includes a connecting sleeve 72, a threaded rod 73, and a sliding head 74; one end of the connecting sleeve 72 is rotatably fitted onto the connecting section 3 mounted on the tray 1, and the other end of the connecting sleeve 72 is rotatably connected to the rotating shaft 71; the sliding head 74 is slidably mounted inside the connecting sleeve 72 along its length; one end of the threaded rod 73 is fixedly connected to the rotating shaft 71, and the other end of the threaded rod 73 is located inside the connecting sleeve 72, and is threadedly connected to one end of the sliding head 74. In specific implementation, rotating the rotating shaft 71 causes the threaded rod 73 to rotate, and the threaded rod 73 causes the sliding head 74 to slide towards the connecting section 3 within the connecting sleeve 72, causing the sliding head 74 to abut against the connecting section 3. After the angle of the connecting section 3 is adjusted, the connecting section 3 is fixed by the friction between the sliding head 74 and the connecting section 3, thereby completing the angle adjustment of the walking frame.

[0040] See Figures 1-8 In other embodiments, a limiting member is installed at one end of the sliding head 74 near the connecting section 3; the limiting member includes an elastic plate 75, hooks 76, and abutment 77; the connecting section 3 is provided with a plurality of grooves 31, which are arranged in a circular array with the axis of the connecting section 3 as the center, and each groove 31 has a raised edge 32 on opposite sides outside the groove; the two ends of the elastic plate 75 are hinged to the abutment 77; the abutment 77 is fixedly installed in the middle of the side of the elastic plate 75 near the connecting section 3; a plurality of hooks 76 are fixedly installed in the side of the elastic plate 75 near the connecting section 3, and the hooks 76 are oriented toward the abutment 77. In practice, the elastic plate 75 can be made of iron, the same material as the spring 65, or other elastic materials. When the sliding head 74 moves, the abutment 77 contacts the connecting section 3. The abutment 77 causes the elastic plate 75 to bend inward, and the hook 76 on the elastic plate 75 rotates inward, so that the hook 76 can be engaged in the groove 31. This limits the connecting section 3 and prevents the connecting section 3 from rotating in both directions.

[0041] See Figure 9In another embodiment, a synchronization mechanism 8 is also included. The synchronization mechanism 8 includes a transmission gear 81 and a reversing gear 82. The transmission gear 81 corresponds one-to-one with the walking frame, and the transmission gear 81 rotates synchronously with the connecting section 3, which is rotatably mounted on the table 1. Both the transmission gear 81 and the reversing gear 82 are rotatably mounted on the table 1, and the reversing gear 82 meshes with the two transmission gears 81. In specific implementation, when one walking frame rotates, the connecting section 3 rotates, and the connecting section 3 drives the transmission gear 81 to rotate. The transmission gear 81 drives the other transmission gear 81 to rotate via the reversing gear 82, so that when controlling the rotation of one walking frame, the other walking frame rotates synchronously in the opposite direction, thereby improving the adjustment speed of the walking frame. Furthermore, the transmission gear 81 rotates synchronously with the connecting section 3 via a transmission assembly. The transmission assembly includes a first sprocket 83, a second sprocket 84, and a chain 85. The first sprocket 83 is coaxially fixed to the connecting section 3, and the second sprocket 84 is coaxially fixed to the transmission gear 81. The first sprocket 83 is connected to the second sprocket 84 via the chain 85. Specifically, the connecting section 3 drives the first sprocket 83 to rotate, the first sprocket 83 drives the second sprocket 84 to rotate via the chain 85, and the second sprocket 84 drives the transmission gear 81 to rotate. This enables long-distance transmission and reduces the diameter of the gear.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
