Title:
TELESCOPIC SINGLE-LEGGED PORTABLE WORKING CHAIR
Document Type and Number:
WIPO Patent Application WO/2018/135801
Kind Code:
A1
Abstract:
The present invention relates to a single-legged portable working chair using a compression repulsive force of a spring body, wherein: when used, the telescopic single-legged portable working chair is worn on a user's body such that, when the user sits down, the spring body is compressed by the weight of the user's body to store power, and when the user stands up, the spring body pushes up the user's body using the compressed power, so that the power consumption required for the sitting and standing actions of the body can be reduced; when the user repeatedly lifts a weight, the load applied to the user's joints and muscles is alleviated by the magnitude of a repulsive force of the spring body, so that injuries to the body due to work over a long period of time can be reduced; and the operation of the spring body is controlled by controlling a trigger device linked with movements of the body preceding the actions for sitting and standing, so that the stability and efficiency of the portable working chair can be increased.
