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] Example 1: see Figure 1-4 , a handrail-based stair climbing auxiliary device, including a horizontally arranged draw bar 1, a downward bayonet 2 is set below one end of the draw bar 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 draw bar The direction is the same and the bayonet can be slid back and forth on the handrail 14 of the stairs; it is characterized in that an active abutting mechanism is also provided, and the active abutting mechanism includes a telescopic device installed telescopically on the right side of the bayonet. The active snap joint 16 in the groove also includes a button 17 located in the direction of the front side surface of the draw rod. Pressing the button 17 can drive the active snap joint to actively extend outward.

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

Embodiment 2

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

Embodiment 3

[0074] Example 3, see Figure 5 The difference between the structure of this embodiment and the first embodiment is that among the two card connectors, the left card connector is a fixed card connector, and the right card connector is the active card connector.

[0075] In this way, the advantages of the above-mentioned two card joint structures can be taken into account. When the device is used for load bearing, the button is pressed to drive the active card joint to extend and be firmly fixed by the cam, forming the effect of two fixed card joints and ensuring the load bearing process. stability and reliability. When the device is pushed forward without bearing force, the button is released, and the active snap joint is retracted backward by the spring force, which is convenient for the device bayonet to slide forward on the armrest, which is smoother and more convenient.

[0076] To sum up, the present invention can help the elderly or the disabled to go upstairs with less...

Abstract

The invention discloses a stair-climbing auxiliary device based on a handrail, which comprises a horizontally arranged pull rod. A downward bayonet is arranged under one end of the pull rod. The width direction of the bayonet is consistent with the length direction of the pull rod and the bayonet can be snapped into the On the handrail of the stairs; it is characterized in that it is also provided with an active pressing mechanism, the active pressing mechanism includes an active clamping joint that is telescopically installed in a telescopic slot on the right side of the bayonet, and also includes an active locking joint located on the front side of the pull rod There is a button in the direction of the surface, and pressing the button can drive the active card connector to actively protrude outward. The invention can help the elderly or the disabled go upstairs more labor-saving, can prevent falling, and has the advantages of better safety, convenient implementation and low cost.

Description

technical field [0001] The invention relates to the technical field of life assistance for the elderly or those with inconvenient legs and feet, in particular to a stair climbing assistance device based on handrails. Background technique [0002] Existing high-rise buildings are usually equipped with elevators, but in some buildings with lower floors and some old buildings, stairs are still used to achieve upper and lower floors. style stairs. In this way, for some elderly people or some disabled people with inconvenient legs and feet, it will be more difficult to climb such stepped stairs, and it is easy to fall down due to exhaustion, causing safety accidents. Especially for the elderly, falling on such steps, the collision between the head and the edge of the steps will directly pose a great threat to life safety. [0003] CN201711032317.3 once disclosed a booster for going up and down stairs; it includes a lift table arranged on a staircase of a residence, and a contro...
