发明名称 Portable writing board structure
摘要 A portable writing board presentation structure has a collapsible writing surface, such as a dry-erase or "white board" surface, and an integral, height-adjustable tripod stand. The writing board structure is defined by first and second injection molded plastic panels, each panel having a writing surface on one side thereof and a non-writing surface on an opposite side thereof. The panels are pivotally coupled to one another to define an open position and a closed position. The open position situates the writing surface in a co-planar relationship to provide a continuous writing surface. The closed position situates the writing surface sides of each panel in a parallel relationship. With respect to the tripod stand, an end section of a telescoping leg is integrally molded into each panel such that the remaining telescoping section of the telescoping leg extends into a recess formed in a non-presentation side surface of the panel.
