Description

Technical Field

[0001] This utility model relates to the field of cane technology, specifically to a fall-prevention cane. Background Technology

[0002] A cane is an assistive tool used to support and balance the body. It typically consists of a pole and a handle and can help people with mobility issues due to illness or age. It helps balance the center of gravity, reduce the burden, and maintain stability while walking. Canes can be divided into common single-leg canes and multi-leg canes. Compared to single-leg canes, multi-leg canes can provide more stable and balanced support and improve the fall prevention effect.

[0003] Although multi-legged crutches have a good anti-fall effect, unlike single-legged crutches which allow for smooth alternating movement, four-legged crutches require all four legs to be placed down simultaneously, resulting in a staggered and slow gait that cannot achieve a natural stride. Furthermore, when used on sloping surfaces, if all four legs are supported on the incline, the rod tilts against the body, limiting the user's range of motion and flexibility, and reducing the support effect. If the rod is kept vertical, only a portion of the four legs will be in contact with the ground, reducing the contact area between the legs and the ground and consequently decreasing the grip, thus reducing the overall stability of the crutches and making it easier for the body to lose balance or fall. Utility Model Content

[0004] In summary, to overcome the shortcomings of the prior art, this utility model provides a walking stick that makes walking smoother and can adapt to different inclines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fall-prevention cane, comprising a pole and a base, the base having a plurality of legs arranged around its center, and also including an elastic element, the bottom of the pole being hinged to the base, the base limiting the swing angle of the pole, the elastic element controlling the pole to move in a direction perpendicular to the base, and the top of the pole having a handle, the handle being oriented in the same direction as the swing direction of the pole.

[0006] With this design, the support legs on the edge of the chassis will rest on the ground during use, while the cane can swing on the chassis. When walking, the cane will thrust forward, and when the support legs are fully in contact with the ground, the cane will be tilted due to its swing, making it easier for the user to hold. The elasticity of the spring element will also provide a forward guiding force, conforming to the slight tilt and sway that naturally occurs when walking, making the walking process smoother and also cushioning the impact of the cane hitting the ground. At the same time, when encountering a slightly inclined surface, the support legs can also fit against the ground without the cane being perpendicular to it. The cane will automatically adapt to the ground during use without manual adjustment, making it convenient to use. The cane also has a swing angle limit, which can only swing within a fixed angle, preventing it from falling at a large angle and not affecting its anti-fall function. The addition of a grip makes it easier to determine the direction of swing, ensuring that the user can set the swing direction to forward.

[0007] Furthermore, the elastic element is a tension spring, and elastic elements are provided on both sides of the rod in the swing direction. The two ends of the elastic elements are respectively connected to the rod and the chassis.

[0008] With this configuration, the tension springs on both sides of the rod will simultaneously apply force to the rod. When the forces on both sides are balanced, the rod will be guided to the center position, which is the angle perpendicular to the chassis. Using tension springs as elastic elements results in a simple structure, low cost, and light weight.

[0009] Furthermore, the rod and the chassis are respectively provided with connecting plates, the connecting plates are provided with connecting holes, and the two ends of the elastic element are located in the connecting holes.

[0010] With this configuration, the hooks on both sides of the tension spring will pass through the connecting holes and hook onto the connecting plate, thus completing the connection through the connecting plate on the rod and the chassis, making installation convenient.

[0011] Furthermore, the hinge axis between the rod and the chassis is located above the chassis, the connecting plate is located below the chassis, the chassis is provided with a movable hole, and the rod is located in the movable hole.

[0012] With this setup, the tension spring will also be located below the chassis, thus being blocked and preventing the user from touching it under normal circumstances, making it safer. Furthermore, the width of the movable hole can exert a preliminary limiting effect on the rod. When the rod swings, the two ends will be blocked when they hit the edge of the movable hole and cannot continue.

[0013] Furthermore, a connecting bottom cover is provided below the chassis and is detachably connected thereto, with the elastic element located within the connecting bottom cover.

[0014] This design allows the connecting cover to completely enclose the tension spring, without even exposing the bottom of the chassis, ensuring that the user will not be touched under any circumstances, thus enhancing safety. It also prevents foreign objects such as stones from falling in and affecting the operation of the tension spring, making it more stable.

[0015] Furthermore, a mounting groove is provided below the chassis, the elastic element is located in the mounting groove, and the inner wall of the connecting bottom cover is threadedly connected to the outer wall of the chassis.

[0016] With this configuration, the connecting bottom cover will rotate and cover the mounting slot at the bottom of the chassis, thus completely enclosing the tension spring and making installation convenient.

[0017] Furthermore, the top surface of the chassis is provided with hinge plates on both sides of the rod, and the rod is hinged to the two hinge plates.

[0018] With this setup, the hinge of the rod can be completed in a conventional way, by having the hinge shaft pass through the hinge plate and the rod. The structure is simple and easy to install.

[0019] Furthermore, the hinge plate is provided with an arc-shaped groove centered on the hinge axis of the rod, and the rod is provided with a limiting rod at the position of the arc-shaped groove.

[0020] With this design, the limiting rod will swing in the arc-shaped groove, which can limit the swing of the rod. The structure is simple.

[0021] Furthermore, the hinge plate is provided with a fixing hole, and the rod body is provided with a positioning hole corresponding to the fixing hole and adapted to the limiting rod. The limiting rod is detachably connected to the rod body.

[0022] With this setup, the rod can be fixed to the hinge plate by pulling out the limit rod and inserting it through the fixing hole into the positioning hole. This completely restricts the swing of the rod when needed, temporarily turning it into an ordinary anti-fall cane. The limit rod can be connected to the rod in various ways, such as interference fit, threaded connection, etc.

[0023] Furthermore, the elastic element is provided in several parts, and the number of elastic elements on both sides of the rod is the same.

[0024] This setup allows for a smaller chassis, thus controlling the spacing between the outriggers. Multiple small tension springs can be used to increase the rebound force of the rods, with the specific number depending on the needs. Attached Figure Description

[0032] With this configuration, the support legs 201 on the edge of the chassis 2 will rest on the road surface during use, while the pole 1 can swing on the chassis 2. When walking, the cane will thrust forward, and when the support legs 201 are fully in contact with the road surface, the pole 1 will be tilted due to its swinging motion, making it easier for the user to hold. The elastic force of the elastic element 3 will also provide a forward guiding force to the user, conforming to the slight tilting and swaying that naturally occurs when walking, making the walking process smoother and also buffering the impact force generated when the cane contacts the road surface. At the same time, when encountering a slightly inclined road surface, the support legs 201 can also fit against the road surface, and the pole 1 does not need to be perpendicular to the road surface. The cane will automatically adapt to the road surface during use without manual adjustment, making it convenient to use. In addition, the pole 1 has a limit on the swing angle, which can only swing within a fixed angle, preventing it from falling at a large angle and not affecting its anti-fall function.

Using tension springs as elastic elements 3 results in a simple structure, low cost, and light weight.

[0035] In this preferred embodiment, the rod body 1 and the chassis 2 are respectively provided with connecting plates 102, the connecting plates 102 are provided with connecting holes 103, and the two ends of the elastic element 3 are located in the connecting holes 103.

[0036] With this configuration, the hooks on both sides of the tension spring will pass through the connecting holes 103 and hook onto the connecting plate 102, thus completing the connection between the rod 1 and the connecting plate 102 on the chassis 2, making installation convenient.

[0037] In this preferred embodiment, the hinge axis between the rod 1 and the chassis 2 is located above the chassis 2, the connecting plate 102 is located below the chassis 2, the chassis 2 is provided with a movable hole 202, and the rod 1 is located in the movable hole 202.

Furthermore, the width of the movable hole 202 can exert a preliminary limiting effect on the rod 1. When the rod 1 swings, its two ends will be blocked when they hit the edge of the movable hole 202, preventing it from continuing.

[0039] In a preferred embodiment, a connecting bottom cover 203 is provided below the chassis 2 and is detachably connected thereto, and the elastic member 3 is located in the connecting bottom cover 203.

[0040] With this design, the connecting cover 203 can completely enclose the tension spring, and even the bottom of the chassis 2 is not exposed, ensuring that the user will not be touched under any circumstances, which is safer. At the same time, it prevents foreign objects such as stones on the ground from falling in and affecting the operation of the tension spring, making it more stable.

[0041] In a preferred embodiment, the chassis 2 is provided with a mounting groove 204 below it, the elastic element 3 is located in the mounting groove 204, and the inner wall of the connecting bottom cover 203 is threadedly connected to the outer wall of the chassis 2.

[0042] With this configuration, the connecting bottom cover 203 will rotate and cover the mounting groove 204 at the bottom of the chassis 2, thus completely enclosing the tension spring and making installation convenient.

[0043] In a preferred embodiment, the top surface of the chassis 2 is provided with hinge plates 205 on both sides of the rod 1, and the rod 1 is hinged to the two hinge plates 205.

[0044] With this configuration, the hinge of rod 1 can be completed in a conventional way by passing the hinge shaft through the hinge plate 205 and rod 1. The structure is simple and easy to install.

[0045] In this preferred embodiment, the hinge plate 205 is provided with an arc-shaped groove 2051 centered on the hinge axis of the rod body 1.

In this way, different limiting angles can be achieved by inserting the limiting rod 104 into the arc-shaped grooves 2051 at different heights. Insertion holes can be provided on the rod body 1 at the corresponding positions of each arc-shaped groove 2051 to facilitate the insertion of the limiting rod 104.

[0046] With this configuration, the limiting rod 104 will swing in the arc groove 2051, which can limit the swing of the rod 1. The structure is simple.
