Technical Field

[0001] This utility model belongs to the field of medical assistive device technology, and in particular relates to a bilateral walking aid. Background Technology

[0002] In today's society, the aging population is becoming an increasingly prominent issue. With the increasing number of elderly people, it is particularly important to equip families with assistive devices suitable for their use. Walking aids are two important assistive devices that are currently widely used in homes. They can effectively improve the quality of life for the elderly and ensure their safety.

[0003] Although there are some high-quality walking aids on the market, their high production costs and prices make them unaffordable for users with financial difficulties, limiting their widespread use. At the same time, some products on the market are designed in ways that do not meet the actual needs of the elderly. Common examples include canes and walking aids. Canes have poor stability, while walking aids are too bulky, inconvenient to move, or lack sufficient flexibility, failing to meet the comfort and convenience requirements of the elderly for daily use.

[0004] Therefore, when designing walking aids, it is necessary not only to ensure the safety and durability of the product, but also to pay attention to human-centered design, taking into account the physiological characteristics and usage habits of the elderly, and improving the product's operability, portability and comfort. There is an urgent need to develop more cost-effective products that are more suitable for the elderly, so as to meet the needs of users with different economic levels and provide practical help to improve the home life of the elderly.

[0005] Therefore, we propose a bilateral walking aid to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problems of existing walking aids being too bulky, inconvenient to move, and having limited functions, and to propose a bilateral walking aid.

[0008] A bilateral walking aid, comprising:

[0009] crossbar;

[0010] Two handrails are symmetrically and fixedly installed above the crossbar;

[0011] Two fixed support legs are symmetrically fixedly installed below the crossbar;

[0012] Two movable support legs are located at both ends of the crossbar. The movable support legs can rotate around the axis of the crossbar to form a movable A-shaped support structure with the fixed support legs. The bottom of the movable support legs is equipped with movable wheels.

[0013] An adjustment structure is used to control the rotation of the movable leg and fix the movable leg in a specified adjustment position;

[0014] The buffer locking structure is used to buffer the downward pressure on the handrail and restrict the rotation of the movable wheels when under pressure.

[0015] Preferably, the top of the handrail is curved to form a gripping part, and a cotton cover is provided on the gripping part.

[0016] Preferably, the adjustment structure includes a pin that passes through the movable support leg and is rotatably connected to the crossbar. The movable support leg has a through hole corresponding to the pin, and the end of the crossbar has a mounting hole corresponding to the pin. A tension spring is provided between the pin and the mounting hole. The outer circumferential surface of the pin is provided with limiting teeth, and the inner walls of both the through hole and the mounting hole are provided with limiting tooth grooves that are adapted to the limiting teeth.

[0017] Preferably, the mounting hole is provided with an anti-detachment groove, and the end of the pin is provided with an anti-detachment ring adapted to the anti-detachment groove.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1-4 A two-sided walking aid includes a crossbar 1, two handrails 2, two fixed legs 3, two movable legs 4, an adjustment structure 5, and a buffer locking structure 6.

[0031] The horizontal bar 1 is set horizontally and is the main structural component.

[0032] Two handrails 2 are symmetrically fixedly installed above the crossbar 1. The top of the handrail 2 is curved to form a gripping part, and a cotton cover 21 is fitted on the gripping part, which is more in line with the human body structure and easier to grip. The cotton cover 21 can increase the comfort of hand gripping.

[0033] Two fixed support legs 3 are symmetrically fixedly installed below the crossbar 1.

[0034] Two movable support legs 4 are located at both ends of the crossbar 1. The movable support legs 4 can rotate around the axis of the crossbar 1 to form a movable A-shaped support structure with the fixed support leg 3. The A-shaped support structure facilitates the angle adjustment of the fixed support leg 3 and the movable support leg 4, which is beneficial for adapting to users of different heights. After the angle is adjusted, the state of the walking aid can be changed. It can not only be used as a walking aid, but the fixed support leg 3 can also be inserted under the mattress to become a bedside guardrail, which effectively improves the home safety of the elderly. When the elderly get out of bed, the guardrail provides necessary support to ensure their safety. When independent walking is required, the function of the walking aid can be activated immediately to meet the needs of different scenarios. The bottom of the movable support leg 4 is equipped with movable wheels 41. When in use, the movable wheels 41 are used to roll, so there is no need to lift the entire walking aid when moving, which is more convenient and practical.

[0035] The adjustment structure 5 is used to control the rotation of the movable support leg 4 and fix the movable support leg 4 in the specified adjustment position.

[0036] Specifically, the adjustment structure 5 includes a pin 51 that passes through the movable support leg 4 and is rotatably connected to the crossbar 1. The movable support leg 4 has a through hole 42 corresponding to the pin 51, and the end of the crossbar 1 has a mounting hole 11 corresponding to the pin 51. A tension spring is provided between the pin 51 and the mounting hole 11. The outer circumferential surface of the pin 51 is provided with a limiting tooth 52. The inner walls of the through hole 42 and the mounting hole 11 are both provided with a limiting tooth groove 53 that matches the limiting tooth 52. During adjustment, the pin 51 is pulled outward to disengage the limiting tooth 52 from the limiting tooth groove 53 in the mounting hole 11. Then, the movable support leg 4 is rotated to adjust the angle. After adjustment, the pin 51 is released, and the pin 51 is reset under the action of the tension spring and re-inserted into the limiting tooth 52 in the mounting hole 11 to achieve locking.

[0037] An anti-detachment groove is provided in the mounting hole 11, and an anti-detachment ring adapted to the anti-detachment groove is provided at the end of the pin 51. The anti-detachment groove and the anti-detachment ring cooperate to limit the pull-out length of the pin 51 and prevent the pin 51 from being pulled out too much.

[0038] The buffer locking structure 6 is used to buffer the downward pressure of the handrail 2 and restrict the rotation of the movable wheel 41 when pressure is applied.

[0039] The movable support leg 4 includes a connecting part and a telescopic part. The connecting part and the telescopic part are connected in a sealed manner, and a buffer spring 43 is provided between the connecting part and the telescopic part. When the armrest 2 is subjected to force, the connecting part moves into the telescopic part and compresses the buffer spring 43, which plays a buffering role. The buffering role can effectively absorb part of the impact force, reduce the impact on the joints and body, thereby reducing the risk of injury and protecting the health of the elderly.

[0040] The buffer locking structure 6 includes a hydraulic cylinder 61 with a telescopic part. A piston 62 is slidably sealed inside the hydraulic cylinder 61. One end of the piston 62 extends out of the hydraulic cylinder 61 near the movable wheel 41 and is fitted with a brake pad 63 corresponding to the movable wheel 41. There is a cavity between the piston 62 and the hydraulic cylinder 61. The cavity is connected to the buffer cavity between the connecting part and the telescopic part through a hydraulic pipe. The cavity and the buffer cavity are filled with hydraulic oil. When the connecting part moves into the telescopic part and compresses the buffer spring 43, the hydraulic oil enters the hydraulic cylinder 61 through the hydraulic pipe and moves the piston 62 downward, causing the brake pad 63 to press against the movable wheel 41 and restrict the rolling of the movable wheel 41. This effectively prevents the movable wheel 41 from slipping during use, greatly reducing the risk of falls. When the elderly move and the handrail 2 is not under force, the movable wheel 41 can rotate freely, facilitating the movement of the walking aid. This design provides necessary stability and support for the elderly when walking, helping to enhance their confidence.

[0041] Working principle:

[0042] By adjusting the angle of the fixed support leg 3 and the movable support leg 4 through the adjustment structure 5, it is possible to adapt to users of different heights. After the angle is adjusted, the state of the walking aid can be changed. It can not only be used as a walking aid, but also the fixed support leg 3 can be inserted under the mattress to become a bedside guardrail, which effectively improves the home safety of the elderly. When the elderly get out of bed, the guardrail provides necessary support to ensure their safety; and when they need to walk independently, the function of the walking aid can be activated immediately to meet the needs of different scenarios.

[0043] During adjustment, pull the pin 51 outward to disengage the limiting tooth 52 from the limiting tooth groove 53 in the mounting hole 11, and then rotate the movable support leg 4 to adjust the angle. After adjustment, release the pin 51, and the pin 51 will reset under the action of the tension spring and re-insert into the limiting tooth 52 in the mounting hole 11 to achieve locking.

[0044] When used as a walking aid, when the handrail 2 is under pressure, the connecting part moves into the telescopic part and compresses the buffer spring 43. Hydraulic oil enters the oil cylinder 61 through the hydraulic pipe and causes the piston 62 to move downward, so that the brake pad 63 presses against the movable wheel 41 and restricts the rolling of the movable wheel 41. This can effectively prevent the movable wheel 41 from slipping during use and greatly reduce the risk of falling. When the elderly move, the movable wheel 41 can rotate freely when the handrail 2 is not under pressure, making it convenient to move the walking aid.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
