Abstract

A portable writing desk is the subject of the present invention. The desk is particularly designed for use on a vehicle steering wheel. A flat surface is provided for resting against the steering wheel and a plurality of hooks extend from the surface for engagement over the rim of the wheel. A writing surface is disposed in spaced relationship to the flat surface and is inclined in the same direction as the steering wheel. The writing surface is hinged so as to provide access to an inner cavity which holds papers, writing instruments, etc. The portable writing desk may also be used in the lap of a person or on a flat planar surface and, in this manner, provides for an incline writing surface that is comfortable and convenient.
