CASTER FOR GEL CHAIR, CAPABLE OF MAINTAINING PROPER POSTURE

摘要

The present invention relates to a caster for a gel chair. More specifically, an inner cover connected to a wheel is connected to the inside of an outer cover. A protrusion connecting the lower part of an elastic spring is formed on one side of the upper part of the inner cover. The protrusion connecting the lower part of the elastic spring is formed on one side of the upper part of the outer cover. The caster for a gel chair can smoothly move like a normal chair when not being used. The caster for a gel chair prevents a slide as the wheel is inserted into the outer cover when a user works while sitting on the chair and also as the lower part of the outer cover comes into contact with the ground. Therefore, the caster for a gel chair enables the user to stably and conveniently use the chair. Specifically, the caster for a gel chair can reduce causes of back pain even if the user sits for long time since a soft gel cushion is installed on the back of the chair to prevent poor posture where the back is bent.;COPYRIGHT KIPO 2020
