Description

BACKGROUND OF THE INVENTION

This invention relates generally to a desk with storage and removable, multi-positional and multi-sided writing surfaces which may be different types of surfaces.
Traditionally, there was the ubiquitous blackboard or slate, which was written on with sticks of chalk. Commonly today, the board is white in color and is written on with special felt markers. The whiteboard provides erasable information, much like the blackboard but offers a different type of writing surface. Often children or artists attempting to achieve a specific type of effect in a sketch or drawing will have a desire to work solely on one type of surface or may desire to use both types of surfaces interchangeably.
Young children often need a smaller sized workstation where they can experiment with different mediums, a vertical surface, similar to that of an easel is ideal for this purpose. Yet the need for a flat table for other various craft products is also existent.
Moreau, U.S. Pat. App. No. 20030226948, teaches an easel workstation consisting of four legs attached to a base so that the legs form a pyramid structure. This design does not include a nonpermanent means to write on the board, nor does it include a flat working surface.
Holdredge, et al., U.S. Pat. No. 6,575,103, teaches a combination table/easel including a worksurface with an erasable surface which is able to be positioned as either a table or easel. However, this is an easily collapsible design, not very sturdy in nature, and does not include a dual sided writing surface or storage capabilities.
Previous systems do not provide for both a flat and upright desk/easel apparatus designed to be compactly stored and stow supplies inside.

SUMMARY OF THE INVENTION

It is envisioned that the present invention may be utilized as a free standing desk with a removable, repositionable upper surface which has a different surface on each side of the upper surface.
