Anti-Tip Chair Foot

摘要

Disclosed is an anti-tip chair leg device that is attachable to the foot of a chair's rear leg, to prevent or reduce the risk of the chair tipping over backwards. This feature of the device is especially beneficial when a child is using the chair. The anti-tip chair leg device has a leg receiver housing mounted on a footplate. The leg receiver housing has means to grip the lower (or foot) portion of a leg of the chair leg received into the leg receiver housing. The grip means holds the foot of the chair leg in place when the chair leg is received in the leg receiver housing. The footplate then acts to shift the distance of a tipping moment-arm of the chair backward and away from the center of mass of the chair and increase the force required to tip the chair backward.
