ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to plan review tables, and more particularly those that are for all weather use and collapsible for easy transportation.
SUMMARY OF THE INVENTION
Accordingly, a primary object of the present invention is to provide an adjustable and collapsible table made of durable plastic or other lightweight materials that can be used in an all weather type environment and is practical.
It is a more specific object of the invention to provide a collapsible table surface which includes two horizontally slidably connected, tubular type surfaces which contain pre-molded guide/stiffeners to ensure rigidity and strategically placed alignment holes on the top and bottom edge of the table surface to obtain various open and closed positions. The top surface has a plan lip or stop to ensure that the blueprints remain on the table during reviewing. One outer edge of the table has a handle for transportation when collapsed.
The legs also are comprised of two vertically tubular type surfaces containing numerous pre-drilled holes which allow various heights and angles to be obtained easily for each individuals independent height requirements. The legs are foldable by use of extruded pins protruding from the upper leg into molded support blocks creating a pivot point. The legs are locked in the open and collapsed position by lock out bolts placed through pre-drilled holes on the molded support blocks. In addition, each leg has an anchor foot plate, that can be fastened to any surface through pre-drilled holes.
It is further object of the present invention to provide a versatile, lightweight, durable and economical blueprint review table for construction superindentents, Forman, engineers, architects and the like to use in any weather environment that is quick and easy to transport.
More objects of the present invention will become obvious as drawings and detailed description to follow are reviewed with drawing reference numbers that correspond.
