Abstract

Abstract A lap desk for use by children while traveling in an automobile has a box-like frame. The desk has a door which forms a compartment for storage of paper, coloring books, etc. and a separate compartment designed for storage of markers and crayons. A circular upstanding holder is designed as a receptacle for beverage containers. The lap desk is attached to a seat belt by straps, and is placed over the child's legs. A strap from the desk extends beneath the child's legs to secure the lap desk during use. An optional pad snaps to the bottom surface of the desk and may be provided with a curvature to receive the legs of a child.
