Problems solved by technology

In this way, due to the instability of the electrical components, once a fault occurs, it will cause loss of power or slippage, which will easily cause the user to fall, and there is a large potential safety hazard.
[0006] In order to solve the above problems, the applicant has applied for a patent on a method of assisting stair climbing to prevent falls, which introduces a device for assisting stair climbing, but there are still some problems in the device that are not reasonable enough in structural design and inconvenient to use. defect

Embodiment 1

[0046] Embodiment 1: see Figure 1-4 , a stair-climbing auxiliary device based on handrails, including a horizontally arranged pull rod 1, a downward bayonet 2 is set under one end of the pull rod 1 (the orientation is described based on the use state of the device), the width direction of the bayonet 2 and the length of the pull rod The direction is the same and the bayonet can be snapped into the handrail 14 of the stairs by sliding back and forth; its feature is that it is also provided with an active pressing mechanism, which includes a telescoping device telescopically installed on the right side of the bayonet. The active clamping joint 16 in the groove also includes a button 17 located in the direction of the front surface of the pull rod. Pressing the button 17 can drive the active clamping joint to actively protrude outward.

[0047] The device can assist the elderly or people with handicapped legs and feet to climb stairs and go upstairs. When in use, the user (that...

Embodiment 2

[0073] Embodiment 2, the difference in structure between this embodiment and embodiment 1 is that the two clamping joints are two fixed clamping joints, and the rest of the structure is the same as that of embodiment 1. In this way, the fixed clip joint can directly bear the force, making the force bearing process of the above effect more stable.

Embodiment 3

[0074] Example 3, see Figure 5 The structural difference between this embodiment and Embodiment 1 is that, among the two snap joints, the left snap joint is a fixed snap joint, and the right snap joint is the active snap joint.

[0075] In this way, the advantages of the above two clamping joint structures can be taken into account. When the device is used for load bearing, pressing the button drives the active clamping joint to protrude and be fixed by the cam, forming the effect of two fixed clamping joints to ensure the load bearing process stability and reliability. When the device is pushed forward without bearing force, the button is released, and the active clamping joint is retracted backward by spring force, which facilitates the device bayonet to slide forward on the armrest, which is smoother and more convenient.

[0076] In summary, the present invention can help the elderly or disabled to go upstairs with less effort, can prevent falling, and has the advantages ...

Abstract

The invention discloses a stairs climbing assisting device based on a handrail. The stairs climbing assisting device comprises a horizontal pull rod, wherein a downward clamping opening is formed in the lower portion of one end of the pull rod, the width direction of the clamping opening is consistent with the length direction of the pull rod, and the clamping opening can be slidably clamped in the handrail of stairs front and back. The stairs climbing assisting device is characterized by further comprising an active abutting mechanism and a button, wherein the active abutting mechanism comprises an active clamping joint which is telescopically installed in a telescopic groove in the right side face of the clamping opening, the button is located on the surface of the front side of the pullrod, and by pressing the button, the active clamping head can be driven to actively stretch out. The stairs climbing assisting device has the advantages that the old or disabled can be helped to go upwards with less effort, and can be prevented from falling over themselves, and has the advantages of being higher in safety, convenient to implement and low in cost.

Description

technical field [0001] The invention relates to the technical field of life assistance for the elderly or persons with inconvenient legs and feet, in particular to a stair climbing auxiliary device based on handrails. Background technique [0002] Existing high-rise buildings are usually equipped with elevators, but some buildings with lower floors and some old buildings still rely on steps to go up and down floors. staircase. Like this, for some elderly people or some handicapped people with inconvenient legs and feet, they will be more strenuous when climbing this step-type stairs, and they will easily fall down due to exhaustion, causing safety accidents. Especially for the elderly, falling on this step, head and step edge collision can directly cause great threat to life safety. [0003] CN201711032317.3 once disclosed a booster for going up and down stairs; it includes a lifting platform arranged on the stair steps of a residence, and a controller for controlling the ...
