A four-legged cane that reduces the risk of tripping for the elderly

Abstract

Disclosed is a four-foot walking stick capable of lowering stumbling risks of an old person. Four supporting feet extend out from four corners of a column foot plate outwards and include three fixed supporting feet and a movable supporting foot, and the movable supporting foot rotating around a vertical shaft on the column foot plate is arranged at the corner closest to the foot of the person and usually stops at a position butting against a retaining column under the action of a rotary spring. When the walking stick falls to the ground, because of geotropic gravity, the movable supporting foot can only move horizontally, and the walking stick can bear force from top to bottom; when the old person carries the walking stick to go forward, the foot of the old person with the body most instable kicks the movable supporting foot, at the moment, the movable supporting foot is free of ground friction, and accordingly, horizontal resistance of the movable supporting foot is insufficient to stumble the old person. Since a roller can be arranged at a grounding position of the movable supporting foot, except for time nodes when the old person is easy to stumble, when the four-foot walking stick is placed flat downwards and the old person kicks the movable supporting foot, friction force between the movable supporting foot and the ground can be decreased under the action of the roller, kicking resistance is also decreased, and further, the stumbling risks of the old person can be minimized maximally.

Description

technical field [0001] The invention relates to the field of nursing equipment, in particular to a four-legged crutch for reducing the risk of tripping by the elderly. Background technique [0002] As we all know, old people often use crutches in order not to fall, and four-legged crutches have four fixed legs. It stretches in the four directions of front left, front right, back left, and back right, and it touches the ground through four anti-slip sleeves. Because it is supported on the ground like the four feet of a stool, it is not easy for the old man to shake the crutch when he walks. Four-legged crutches have almost become an essential tool for the elderly to walk today. When an old man walks with a four-legged cane, he usually lifts it up and lays it flat. For a person holding a cane with his right hand, the position of the four legs is the same. In order not to make the right foot stand too close to the foot, the crutch column is always installed on the side of the...
