Abstract

A type of spring-loaded leg base includes a base, a spring, and a connecting component. The base has a hollow chamber. The spring is placed inside the chamber. The connecting component is a unified component of a leg sleeve, a connecting bar and a spring cap. By passing the connecting bar through the grooved track and placing the spring cap on the top of the spring, the leg sleeve can be locked in position on the chair frame to create flexible support. This mechanism creates the rocking function for a regular chair.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to a chair accessory, and more particularly to a type of spring-loaded leg base. The base is placed where the chair frame touches the ground so that the chair can rock properly.Technical Background[0002]A rocking chair is a common leisure facility that has a rocking feature. However, it typically relies on arched bar components to have contact with the ground to create rocking movements. This causes the chair to remain in an unstable condition all the time, limiting its use to only certain leisure occasions. As such, manufacturers have improved on its defect, so that rocking chairs can work in a stable mode and a rocking mode.[0003]For example, a collapsible and portable rocking chair disclosed in Published U.S. Patent Application Publication U.S.20150282625A1. It includes an expandable and collapsible seat frame. That seat frame consists of a pair of side frame components and a connecting bar that ...
