Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of walking aids, and particularly relates to a walking aid. BACKGROUND

[0002] A walking aid, such as a walking stick, is an auxiliary device for assisting human body to support body weight, maintain balance and walk. Such a device provides important help for patients or the elderly users with weak strength and poor balance in rehabilitation treatment and daily life.

[0003] However, when the user holds the walking stick, the walking stick may contact the ground at various angles. When the walking stick contacts the ground in a non-vertical state, only part of the bottom plate of the walking stick contacts the ground, which reduces the friction between the walking stick and the ground, and the walking stick is easy to slip, so that the walking stick cannot play a supporting role, which brings safety hazards to the user.

[0014] In some embodiments, the chassis further includes an inner cavity and a through hole for communicating with the second cavity and the inner cavity; the limiting member includes: a limiting rod, which passes through the first cavity and the second cavity, and one end of the limiting rod extends out of the rotating member and movably passes through the through hole, so as to limit the rotation angle of the rotating member when the rotating member swings relative to the chassis in any direction; and a first blocking part, which is located in the inner cavity and connected to one end of the limiting rod extending out of the through hole, so as to limit the limiting rod from disengaging from the chassis.

[0015] In some embodiments, the limiting member further includes a baffle, which is sleeved on the limiting rod and located between the first blocking part and the through hole. The baffle has a through hole through which the limiting rod passes. The diameter of the baffle is larger than the inner diameter of the through hole, the inner diameter of the through hole is smaller than the inner diameter of the through hole, and the diameter of the first blocking part is larger than the inner diameter of the through hole.

[0037] The terminology used in this application specification is for the purpose of describing particular embodiments only and is not intended to limit the application. Descriptions using terms such as "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0038] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0039] Please see Figures 1 to 3 This application provides a walking aid device 100, including a handheld part 10, a rod assembly 20, a rotating assembly 30, and a base 40. The handheld part 10 is for the user to hold. The rod assembly 20 is connected to the handheld part 10 and the rotating assembly 30. The rotating assembly 30 is rotatably connected to the base 40, allowing the rotating member 31 to swing relative to the base 40 in any direction. The base 40 is used to abut against a support surface to facilitate walking with the assistance of the user. Exemplarily, the support surface can be a flat ground or a sloped surface, etc.

[0040] Please see Figures 6 to 7 The rotating assembly 30 includes a rotating member 31, a limiting member 32, and an elastic reset member 33. One end of the rotating member 31 is rotatably connected to the chassis 40, so that when the rotating member 31 swings relative to the chassis 40 in any direction, the chassis 40 remains relatively stationary with respect to the surface to be supported. The other end of the rotating member 31 is connected to the rod assembly 20. A cavity is formed inside the rotating member 31, and the limiting member 32 passes through the cavity. One end of the limiting member 32 extends out of the rotating member 31 and is movably connected to the chassis 40 to limit the rotation angle of the rotating member 31 when it swings relative to the chassis 40 in any direction. The elastic reset member 33 is sleeved on the limiting member 32 and confined within the cavity. When the rotating member 31 swings relative to the chassis 40 in any direction, it compresses the elastic reset member 33, which provides an elastic reset force to help the rotating member 31 return to its initial position. For example, the initial position can be a position perpendicular to the surface to be supported.

[0041] The walking aid 100 of this embodiment is rotatably connected to the chassis 40 via a rotating member 31. This allows the chassis 40 to remain relatively stationary with respect to the surface to be supported when the rotating member 31 swings relative to the chassis 40 in any direction. This enables the user to adjust the angle of the walking aid 100 according to different needs, adapting to different terrains or walking postures. The handheld part 10, the rod assembly 20, and the rotating assembly 30 can swing flexibly as a whole, while the chassis 40 maintains stable contact with the surface to be supported. Simultaneously, the limiting member 32 restricts the rotation angle of the rotating member 31, satisfying flexibility while preventing excessive rotation that could compromise safety. The elastic reset member 33 helps the rotating member 31 return to its initial position, allowing the handheld part 10, the rod assembly 20, and the rotating assembly 30 to quickly reset after tilting. The elastic reset member 33 is fitted onto the limiting member 32 and confined within the cavity to achieve an elastic connection between the rotating member 31 and the chassis 40. When the rotating member 31 swings, it can compress the elastic reset member 33 to achieve an angle tilt. While meeting a certain tilt angle, it can also ensure the maximum contact area between the chassis 40 and the surface to be supported. Through the above settings, when using the walking aid 100, the user can contact the surface to be supported at various angles, ensuring that the entire chassis 40 contacts the surface to be supported, thereby helping the user maintain balance and stability, preventing slippage, and improving safety.

[0042] Understandably, the fact that the rotating component 31 swings in any direction relative to the chassis 40 means that the rotating component 31 can swing in any direction in the 360° circumferential direction relative to the vertical axis, such as forward, backward, left, right, etc.

[0043] For example, by setting the limiting member 32, the rotation angle of the rotating member 31 can be limited to a preset angle range. The preset angle range can be designed according to specific needs. For example, the rotating member 31 can rotate to a range of 0°-45° relative to the vertical axis, as long as the needs are met. The specific angle is not specifically limited here.

[0044] In some embodiments, the elastic reset member 33 can be a spring, which is sleeved on the limiting rod 321. This allows for an elastic connection between the chassis 40 and the rotating member 31, while also providing an elastic reset force to assist the rotating member 31 in quickly resetting.

[0045] Please see Figures 6 to 7In some embodiments, the rotating component 31 includes a rotating rod 31a and a spherical connecting portion 31b, wherein a cavity is disposed in the rotating rod 31a, and the rotating rod 31a is connected to the rod assembly 20 and the spherical connecting portion 31b. The chassis 40 is provided with a rotating groove 41 adapted to the spherical connecting portion 31b, and the spherical connecting portion 31b is rotatably disposed in the rotating groove 41. Thus, through the cooperation between the spherical connecting portion 31b and the rotating groove 41, not only can the rotating component 31 swing in any direction relative to the chassis 40, but the installation process is also simpler and faster, reducing installation difficulty and cost. During rotation, the spherical connecting portion 31b can play a certain buffering role, reducing structural damage caused by impact or vibration, thereby reducing loosening caused by wear.

[0046] In some embodiments, the spherical connecting portion 31b is a hemispherical structure, and the rotating groove 41 is constructed as a hemispherical groove adapted to the spherical connecting portion 31b.

[0047] Please see Figures 6 to 9 In some embodiments, the walking aid 100 further includes a protective pad 50, which surrounds the edge of the rotating groove 41. An annular portion 313 is provided around the end of the rotating rod 31a connected to the spherical connecting portion 31b, and this annular portion 313 elastically abuts against the protective pad 50. Thus, the cooperation between the protective pad 50 and the annular portion 313 prevents the rotating component 31 from wearing down the chassis 40, providing protection. The elastic force of the elastic reset member 33 creates an elastic connection between the rotating component 31, the protective pad 50, and the chassis 40, allowing the rotating component 31 to swing in any direction by compressing the elastic reset member 33. This ensures maximum contact area between the chassis 40 and the surface to be supported at larger tilt angles, while the cooperation between the spherical connecting portion 31b and the rotating groove 41 provides better stability.

[0048] In some embodiments, the protective pad 50 may be made of elastic materials such as silicone or rubber.

[0049] In some embodiments, the annular portion 313, the spherical connecting portion 31b, and the rotating rod 31a can be integrally formed or separately connected.

[0050] Please see Figures 6 to 7In some embodiments, along the extending direction of the rotating member 31, the cavity includes a first cavity 311 facing the handheld part 10 and a second cavity 312 facing the chassis 40. A limiting member 32 passes through the first cavity 311 and the second cavity 312, with one end of the limiting member 32 extending out of the second cavity 312 from the rotating member 31. An elastic reset member 33 is confined within the first cavity 311. Thus, confining the elastic reset member 33 within the first cavity 311 achieves an elastic connection between the rotating member 31 and the chassis 40. When the rotating member 31 swings, it can compress the elastic reset member 33 to achieve an angle tilt, ensuring maximum contact area between the chassis 40 and the surface to be supported while maintaining a certain tilt angle. Furthermore, the elastic reset member 33 helps the rotating member 31 return to its initial position, allowing the handheld part 10, the rod assembly 20, and the rotating assembly 30 to quickly return to their original positions after tilting as a whole.

[0051] Please see Figures 6 to 7 In some embodiments, the chassis 40 further includes an inner cavity 42 and a through hole 43 for connecting the second cavity 312 and the inner cavity 42. The limiting member 32 includes a limiting rod 321 and a first blocking portion 322. The limiting rod 321 passes through the first cavity 311 and the second cavity 312, with one end extending out of the rotating member 31 and movably passing through the through hole 43, to limit the rotation angle of the rotating member 31 when it swings relative to the chassis 40 in any direction. The first blocking portion 322 is located in the inner cavity 42 and connected to the end of the limiting rod 321 extending out of the through hole 43, to prevent the limiting rod 321 from detaching from the chassis 40. Therefore, the inner cavity 42 and the through hole 43 facilitate the movable connection between the chassis 40 and the limiting rod 321. The limiting rod 321 and the first blocking part 322 limit the tilt angle range of the rotating part 31, which can satisfy the flexibility while avoiding the rotating part 31 from rotating too much and affecting safety.

[0052] Please see Figure 6 , Figure 7 and Figure 9In some embodiments, the limiting member 32 further includes a baffle 60, which is sleeved on the limiting rod 321 and located between the first blocking part 322 and the through hole 43. The baffle 60 has a through hole 61 through which the limiting rod 321 passes. The diameter of the baffle 60 is larger than the inner diameter of the through hole 43, the inner diameter of the through hole 61 is smaller than the inner diameter of the through hole 43, and the diameter of the first blocking part 322 is larger than the inner diameter of the through hole 61. For example, the diameter of the limiting rod 321 can be less than or equal to the inner diameter of the through hole 61. Therefore, through the above arrangement, the limiting rod 321 can pass through the through hole 43 and the through hole 61 and has a certain range of motion, allowing the rotating member 31 to rotate relative to the chassis 40 while limiting the rotation range of the rotating member 31. Simultaneously, one end of the limiting rod 321 can be restricted within the inner cavity 42 of the chassis 40 by the first blocking part 322, thereby preventing the limiting rod 321 from detaching from the chassis 40.

[0053] In some embodiments, the first blocking part 322 and the limiting rod 321 can be integrally formed or connected separately. When the first blocking part 322 and the limiting rod 321 are connected separately, the first blocking part 322 can be fixed to the limiting rod 321 by means of fasteners such as nuts, threaded connections or other installation methods.

[0054] In some embodiments, the limiting member 32 further includes a second blocking portion 323, which is connected to one end of the limiting rod 321 located in the first cavity 311. A partition 314 is provided inside the rotating member 31, separating the first cavity 311 and the second cavity 312. One end of the elastic reset member 33 abuts against the second blocking portion 323, and the other end of the elastic reset member 33 abuts against the partition 314. Thus, the second blocking portion 323 restricts the upward movement of the elastic reset member 33, and the partition 314 restricts the downward movement of the elastic reset member 33, thereby confining the elastic reset member 33 within the first cavity 311 and preventing it from overstepping its bounds.

[0055] In some embodiments, the second blocking part 323 and the limiting rod 321 can be integrally formed or separately connected. When the second blocking part 323 and the limiting rod 321 are separately connected, the second blocking part 323 can be fixed to the limiting rod 321 by means of fasteners such as nuts, threaded connections or other installation methods.

[0056] Please see Figures 1 to 5In some embodiments, the rod assembly 20 includes a telescopic structure 21, which includes a first telescopic rod 211, a second telescopic rod 212, and a positioning member 213. The first telescopic rod 211 is connected to the handheld part 10, and a receiving cavity 2111 is formed within the first telescopic rod 211. Along the extension direction of the first telescopic rod 211, the first telescopic rod 211 is provided with a plurality of spaced-apart limiting holes 2112 that communicate with the receiving cavity 2111. The second telescopic rod 212 is connected to the rotating member 31 and can extend or retract into the receiving cavity 2111. The positioning member 213 is connected to the second telescopic rod 212, and when the second telescopic rod 212 extends into the receiving cavity 2111, it is engaged with any of the limiting holes 2112 by the positioning member 213 to adjust the length of the telescopic structure 21. Therefore, by setting the positioning element 213 and the limiting hole 2112, the length of the telescopic structure 21 can be adjusted, that is, the height of the pole assembly 20 can be adjusted arbitrarily according to the user's needs, so as to facilitate the use of the walking aid device 100.

[0057] For example, the positioning member 213 may be an integrally formed or separately connected to the outer peripheral wall of the second telescopic rod 212. The protrusion is engaged with the limiting hole 2112 to fix the relative position of the first telescopic rod 211 and the second telescopic rod 212. The length of the telescopic structure 21, that is, the height of the rod assembly 20, can be adjusted by adjusting the position of the protrusion and the limiting hole 2112.

[0058] In some embodiments, the telescopic structure 21 further includes a clamping member 214. After the positions of the first telescopic rod 211 and the second telescopic rod 212 are fixed, the clamping member 214 can lock the first telescopic rod 211 and the second telescopic rod 212, thereby preventing the first telescopic rod 211 and the second telescopic rod 212 from swinging left and right.

[0059] Of course, in other embodiments, the telescopic structure 21 may not be limited to using the cooperation of the positioning member 213 and the limiting hole 2112 to achieve telescopic adjustment, and may also be implemented in other ways.

[0060] In some embodiments, the rod assembly 20 further includes a folding structure 22, through which the second telescopic rod 212 is connected to the rotating member 31. The folding structure 22 includes a first rod 221, a second rod 222, and an elastic connecting portion 223. The first rod 221 is detachably connected to the second telescopic rod 212. One end of the second rod 222 is detachably connected to the first rod 221, allowing the first rod 221 and the second rod 222 to be separated from and folded or coaxially connected to the second telescopic rod 212. The other end of the second rod 222 is connected to the rotating member 31. The elastic connecting portion 223 connects the first rod 221 and the second telescopic rod 212, and is used for elastic stretching when the first rod 221 and the second rod 222 are separated from the second telescopic rod 212. Therefore, when the walking aid 100 is not in use, the above-described configuration allows the first rod 221 and the second rod 222 to separate from the second telescopic rod 212 and fold, reducing the size of the walking aid 100 for easier storage. The elastic connection 223 ensures that the first rod 221 and the second rod 222 can be folded without detaching from the walking aid 100. When the walking aid 100 needs to be used again, the first rod 221, the second rod 222, and the second telescopic rod 212 can be coaxially connected, facilitating use.

[0061] For example, the end of one of the second rod 222 and the second telescopic rod 212 can be nested in the other, and the end of one of the first rod 221 and the second rod 222 can be nested in the other, so as to achieve a coaxial connection between the first rod 221, the second rod 222 and the second telescopic rod 212.

[0062] For example, the elastic connection 223 can be a long, elastic object such as an elastic rope.

[0063] It should be noted that the walking aid device 100 in this application embodiment may only have a telescopic structure 21 or only have a folding structure 22, or may have both a telescopic structure 21 and a folding structure 22, to facilitate the use of the walking aid device 100.

[0064] In some embodiments, the handle 10 has a flexible layer at least in the area for the user to grip. For example, the flexible layer may be a flexible material such as soft rubber, which, when applied to the handle 10, can alleviate the pressure on the user's hand from holding the handle 10 for a long time and improve user comfort.

[0065] For example, the handheld portion 10 may have a flexible layer only in the portion for the user to hold, or the flexible layer may be provided on the entire surface of the handheld portion 10.

[0066] In some embodiments, the handgrip 10 is provided with an anti-slip structure at least in the area for the user to grip. For example, the protective structure may be an anti-slip pattern, anti-slip protrusion, or other structure. Since the user's hands tend to sweat after holding the handgrip 10 for a long time, this embodiment of the application increases the friction to a certain extent by adding an anti-slip structure to the handgrip 10, thereby achieving an anti-slip effect.

[0067] For example, the handheld part 10 may have a protective structure only in the portion for the user to hold, or it may have a protective structure on the entire surface of the handheld part 10.

[0068] Please see Figures 1 to 4 as well as Figures 6 to 9 In some embodiments, the chassis 40 includes a base 40a and a support portion 40b disposed at the bottom of the base 40a. A rotating groove 41, an inner cavity 42, and a through hole 43 are all provided on the base 40a. The support portion 40b abuts against the support surface, and the rotating assembly 30 is rotatably connected to the base 40a. At least three support portions 40b are provided, and these at least three support portions 40b are centrally symmetrically arranged about the centerline of the base 40a. Thus, the base 40a and the support portions 40b provide support, and the arrangement of at least three support portions 40b disperses the weight of the chassis 40, reducing the risk of single-point stress and improving overall stability. The centrally symmetrical layout helps maintain the balance of the chassis 40 on the support surface, reducing swaying or tipping caused by a shift in the center of gravity, allowing the chassis 40 to be stably supported on the support surface.

[0069] In some embodiments, the base 40a may be circular in shape (e.g., Figure 1 (as shown), triangles with rounded corners (such as) Figure 2 As shown), irregular shapes (such as...) Figure 3 (as shown) regular or irregular shapes.

[0070] In some embodiments, the bottom of the support portion 40b may be provided with anti-slip patterns, anti-slip protrusions, or other structures to increase friction and thus provide an anti-slip function.

[0071] Without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples.

[0072] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
