Chair having retractable cup holder

摘要

A stackable molded plastic chair has a cup holder is connected to a cylindrical boss on the underside of a chair arm for movement between a retracted position lying underneath the chair arm and an open position extending away from the arm of the chair. The cup holder has a tubular boss having a first portion extending from the top surface of the cup holder and a second portion extending from the bottom surface of the cup holder. The first portion is at least partially within the cylindrical boss on the chair arm. A pin within the tubular boss has two or more spaced apart legs each leg having a foot. As the pin is inserted into the tubular boss the legs will move inward and then will move outward when the feet reach a recess on the inside surface of the cylindrical boss on the chair arm. The feet are each sized and configured to fit into the recess and the legs preferably have an outward curvature. The use of multiple legs having an outward curvature allows the pin to pop free when an excessive force is applied to the cup holder releasing the cup holder from the chair arm without breaking either the cup holder or the chair arm.
