Collapsible Tray for Fold-Up Chair

Abstract

A collapsible tray for use with portable chairs. The tray is mounted to the chair frame by a mounting bracket or clamp. The horizontal support is connected to the vertical support by a pivoting connector, which allows the tray to swing out of the way for easy access. The tray surface itself is made of flexible material and is attached to two tray supports. The two tray supports are connected using two hinged extensions connected to either end of the tray supports. The hinged extensions are connected to the horizontal support by a connector to the support allowing the extensions to pivot and fold. Opening or closing the tray may be accomplished by folding the extensions in or out. The tray can be easily collapsed which allows it to be stored with the chair, or carried in the storage bag with the chair itself.
