Description

Technical Field

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

[0002] A walking aid is a device designed to assist elderly people, patients, or people with disabilities who have difficulty moving around to help them walk or exercise their limbs. Most existing walking aids have a simple frame structure, meaning users need to move from a bed or chair into the aid. Users with mobility impairments often find this difficult to accomplish on their own, making it challenging to use existing walking aids. Furthermore, while some walking aids include a seat, the process of moving from standing to sitting still requires users to actively adjust their position, get up, and sit down, making the transition difficult and increasing the user's burden and potential risks. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a walking aid that allows users to get up from a bed or sofa when the seat is folded up. After getting up, the seat can be folded up, allowing users to sit down and rest at any time during walking.

[0004] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0005] This invention provides a walking aid, comprising:

[0006] Main frame, motor, seating conversion device and battery;

[0007] Both the sitting / standing conversion device and the battery are mounted on the main frame;

[0008] The main frame includes an electric cylinder and a fixed frame. The electric cylinder is located at the bottom of the fixed frame, and the motor is located on the electric cylinder.

[0009] The battery is connected to the motor to provide power to the motor, which can drive the electric cylinder to move, thereby pushing the fixed frame to make piston movement;

[0010] The sitting-standing conversion device includes a seat plate, a connecting rod, and a connecting shaft;

[0011] The seat plate is rotatably connected to the electric cylinder via a connecting shaft;

[0012] One end of the connecting rod is rotatably connected to the main frame, and the other end can be installed on the movable end of the seat plate through a connecting shaft to fix the seat plate.

[0013] The seat plate can be adjusted in angle via the connecting shaft and the connecting rod.

[0014] Furthermore, the main frame also includes a front frame and a telescopic forearm;

[0015] The fixing frame is movably connected to the top of the front frame via a pivot.

[0016] The telescopic forearm is fixed to the side of the fixed frame via a pivot.

[0017] Furthermore, the main frame also includes a first handrail and a second handrail;

[0018] The first handrail is fixed to the telescopic forearm;

[0019] The second handrail is fixed to the side of the fixed frame, opposite to the extension direction of the telescopic forearm.

[0020] Furthermore, a control button is fixed on the surface of the first handrail for controlling the operation of the motor;

[0021] The telescopic forearm is also equipped with a hook at the end where the first handrail is installed.

[0022] Furthermore, a charging port is provided on the surface of the battery.

[0023] Furthermore, the main frame also includes front wheels and rear wheels;

[0024] The rear wheel is connected to the bottom of the electric cylinder;

[0025] The front wheel is connected to the bottom of the front frame.

[0026] Furthermore, a support frame is fixed to the lower end of the electric cylinder, and the rear wheel is installed below the support frame;

[0027] The rear wheel includes multiple unidirectional directional wheels.

[0028] Furthermore, an angle adjuster is fixed below the seat plate to control the rotation angle of the seat plate.

[0029] Furthermore, the main frame body is also provided with armpit auxiliary support, elbow auxiliary support, chest auxiliary support and table board on the side;

[0030] The elbow support, the chest support, and the table can be snapped onto the surface of the telescopic forearm.

[0031] The axillary auxiliary support can be mounted on the side of the mounting frame via a fixing rod.

[0032] Furthermore, rubber pads are fixed to the surfaces of both the first and second handrails;

[0033] The seat panel, the armpit support, the elbow support, and the chest support are all filled with sponge.

[0034] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0035] The walking aid provided by this invention is equipped with an electric cylinder, a motor, a battery, and a fixed frame. The battery provides power to the motor, which drives the electric cylinder to move, thereby pushing the fixed frame to make piston movements to raise and lower the walking aid. This allows the patient to adjust the posture of the walking aid according to their own condition. After the patient holds the first handrail and ensures that it is stable, they can control the operation of the motor through the control button on the first handrail, so that the electric cylinder drives the fixed frame to slowly rise until the legs are perpendicular to the ground and then stop raising and lowering. This helps the patient go from sitting to standing, and the front frame of the main frame ensures walking safety, allowing patients with walking difficulties to walk independently.

[0036] The walking aid provided by this invention can adjust the overall height of the main frame so that the overall height of the walking aid is consistent with the height of the patient when sitting down. Furthermore, by further setting up a seat board, connecting rod and connecting shaft, the accompanying person can flip the seat board so that the patient can sit down and rest anytime and anywhere, avoiding discomfort after standing or walking for a long time. In addition, with the rear wheels with one-way directional wheels, the patient can maintain a stable state during rest, preventing the walking aid from moving or wobbling and causing the patient to fall over, thus improving the convenience and safety of the walking aid.

[0037] The walking aid provided by this invention provides better support for patients by setting up axillary, chest, and elbow auxiliary supports, preventing patients from tilting or falling when getting up. It also helps patients maintain stability while walking independently. Furthermore, the sponge filling inside the axillary, chest, and elbow auxiliary supports can prevent pressure on the patient's armpits, chest, and elbows during long-term walking, thus improving patient comfort.

Detailed Implementation

[0050] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0051] Example 1

[0052] Please see Figures 1-5This embodiment provides a walking aid, which includes a main frame 1 and a motor 2, a seat 3 and a connecting rod 4 mounted on the main frame 1. The main frame 1 includes a front frame and a front wheel 101, a rear wheel 102, an electric cylinder 103, a first handrail 105, a second handrail 106, a telescopic forearm 107 and a fixing frame 108 mounted at the bottom of the front frame. The front wheel 101 is mounted on the lower end of the front frame, and the fixing frame 108 is movably connected to the upper end of the front frame via a pivot. The rear wheel 102 is fixed to the lower end of the electric cylinder 103. The telescopic forearm 107 is fixed to the side of the fixing frame 108 via a pivot. The hook 104 and the first handrail 105 are fixed to one end of the telescopic forearm 107, and the second handrail 106 is fixed to the side of the fixing frame 108.

[0053] In this embodiment, the patient can adjust the posture of the walker according to their own condition. After the patient holds the first handrail 105 and ensures that it is stable, the patient can control the motor 2 to operate through the control button on the first handrail 105, so that the electric cylinder 103 drives the fixed frame 108 to rise slowly until the legs are perpendicular to the ground and the lifting stops. This helps the patient go from sitting to standing, and the front frame of the main frame 1 can ensure the safety of walking, allowing patients with walking difficulties to walk independently.

[0054] The seat plate 3 can be movably connected to the side of the electric cylinder 103 via a rotating shaft. A connecting shaft 6 is movably connected to the upper end of the seat plate 3, and a connecting rod 4 can be installed on the upper end of the seat plate 3 via the connecting shaft 6. The upper end of the connecting rod 4 is fixed to the side of the fixing frame 108. The angle of the seat plate 3 can be adjusted via the connecting shaft 6 and the connecting rod 4. An angle adjuster is fixed below the seat plate 3, and the angle adjuster can control the rotation angle of the seat plate 3. By adopting the above technical solution, the angle adjuster can adjust the maximum rotation angle of the seat plate 3 to ensure that the two seat plates 3 can be laid flat. After the two seat plates 3 are laid flat, they can overlap each other for the patient to sit down and rest. At the same time, when the seat plate 3 is lifted, it is convenient for the patient to move to the middle position of the walker.

[0055] A support frame 109 is fixed to the lower end of the electric cylinder 103. The rear wheels 102 are installed below the support frame 109. There are two sets of rear wheels 102, and each set of rear wheels 102 has two unidirectional directional wheels. The motor 2 is fixed to the surface of the electric cylinder 103, and the motor 2 and the electric cylinder 103 can be electrically connected. By adopting the above technical solution, multiple rear wheels 102 with unidirectional directional wheels can keep the patient in a stable state during rest, avoid the walking aid from moving or shaking, and prevent the patient from falling over, thereby improving the convenience and safety of the walking aid.

[0056] Two control buttons are fixed to the surface of the first armrest 105, and the two control buttons are located on the same side. They control the raising and lowering of the machine respectively. There are two first armrests 105, and the control buttons can be fixed to the surface of either first armrest 105. A hook 104 is also fixed to one end of the telescopic forearm 107, and the position of the hook 104 corresponds to that of the first armrest 105. By adopting the above technical solution, the two control buttons can control the forward and reverse rotation of the motor 2 respectively, thereby controlling the extension and retraction of the electric cylinder 103, and thus controlling the raising and lowering of the walker. This allows the walker to adjust its shape according to the patient's needs. At the same time, the control buttons can be installed on the corresponding first armrest 105 surface according to the patient's own situation.

[0057] A battery 5 is also attached to the surface of the main frame 1. The battery 5 has a charging port 501 on its surface. The battery 5 can be electrically connected to the control button, motor 2 and electric cylinder 103. By adopting the above technical solution, the battery 5 can provide power to the control button, motor 2 and electric cylinder 103. At the same time, the battery 5 is attached to the surface of the main frame 1. When the power inside the battery 5 is exhausted, the battery 5 can be removed from the surface of the main frame 1, a new battery 5 can be replaced, and the old battery 5 can be charged through the charging port 501.

[0058] Please see Figures 6-8 The patient controls the operation of motor 2 via a control button. Motor 2 controls the electric cylinder 103 to retract downwards, thereby causing the fixed frame 108 fixed at the upper end of the electric cylinder 103 to move downwards. The front frame, which is movably connected to the fixed frame 108, moves forward with the cooperation of the front wheel 101, thereby causing the walker to descend as a whole. At the same time, with the cooperation of connecting rod 4 and connecting shaft 6, the seat plate 3 can be rotated. The angle adjuster can limit the maximum rotation angle of the seat plate 3, so that the seat plate 3 can be laid flat. After the two seat plates 3 are laid flat, they can overlap each other, making it convenient for the patient to sit on the surface of the seat plate 3. The connecting rod 4 and connecting shaft 6 can provide support for the seat plate 3, while preventing the seat plate 3 from continuing to flip after bearing a large pressure, causing the patient to fall off the surface of the seat plate 3.

[0059] The walking aid provided in this embodiment can adjust the overall height of the main frame 1 so that the overall height of the walking aid is consistent with the height of the patient when sitting down. At the same time, the accompanying person can assist in flipping the seat board 3 so that the patient can sit down and rest anytime and anywhere, avoiding discomfort after standing or walking for a long time. In addition, with the rear wheel 102 with one-way directional wheels, the patient can maintain a stable state during rest, preventing the walking aid from moving or wobbling, which could cause the patient to fall over, thus improving the convenience and safety of the walking aid.

[0060] Example 2

[0061] Please see Figures 9-10Based on Embodiment 1, the main frame body is further provided with axillary auxiliary support 7, elbow auxiliary support 8, chest auxiliary support 9, and table 10 on its sides. The elbow auxiliary support 8, chest auxiliary support 9, and table 10 can be snapped onto the surface of the telescopic forearm 107. The axillary auxiliary support 7 can be installed on the side of the fixed frame 108 via a fixing rod. Rubber pads are fixed to the surfaces of the first handrail 105 and the second handrail 106. The seat board 3, axillary auxiliary support 7, elbow auxiliary support 8, and chest auxiliary support 9 are all filled with sponge. The present invention, through the axillary auxiliary support 7, chest auxiliary support 9, and elbow auxiliary support 8, can better support the patient, preventing the patient from tilting or falling when getting up. It can also help the patient maintain a stable state during independent walking. Furthermore, the sponge filling the axillary auxiliary support 7, chest auxiliary support 9, and elbow auxiliary support 8 can prevent pressure on the patient's armpits, chest, and elbows during long-term walking, thus improving the patient's comfort.

[0062] Working principle: Step 1, getting on the machine: The user moves to a suitable position for getting on the machine (such as at the corner of the bed or on the seat). The assistant will use the control buttons on the surface of the first armrest 105 to control the walker to adjust to the lowest position, open the seat board 3, and move it in front of the patient.

[0063] Step 2, Getting Up: The patient chooses to wear accessories such as axillary support 7, chest support 9, and elbow support 8 according to their own needs. By controlling the motor 2 through the control button at the first handrail 105, the electric cylinder 103 drives the fixed frame 108 to slowly rise until the legs are perpendicular to the ground, and then stops rising and falling. This helps the patient go from sitting to standing, and the front frame of the main frame 1 ensures the safety of walking, allowing patients with walking difficulties to walk independently.

[0064] Step 3, walking: The accompanying person or the patient manually flips the seat panel 3 to connect them, and then the patient pushes the walker. With the cooperation of the front wheel 101 and the rear wheel 102, the patient can walk independently using the walker.

[0065] Step 4, Rest-Stand-Up Cycle: The patient controls the motor 2 via the control button on the surface of the first armrest 105, which in turn controls the electric cylinder 103 to retract, thereby causing the walker to descend as a whole. When the walker descends to a suitable height, the buttocks reach the seat to rest. The patient then controls the motor 2 to reverse via the control button on the surface of the first armrest 105, which causes the walker to rise as a whole until the buttocks are completely off the seat and the legs are perpendicular to the ground, allowing the patient to walk without interference.

[0066] Step 5, Disembarkation: The patient moves the walker to a suitable position independently, and the assistant helps adjust the position to ensure that the patient's buttocks can contact the seating surface after descent. Then, the seat board 3 is opened, and the control method of step 4 is repeated to control the walker to descend as a whole until the buttocks reach the edge of the bed or the seat surface. Finally, the patient leaves the main frame 1, and the assistant helps the patient lie down or adjust their position, and then moves the walker to a suitable position.
