Modular Portable Writing And Projection System Having Variable Curvature
Modular Portable Writing And Projection System Having Variable Curvature
US Patent:
2011004, Feb 24, 2011
Filed:
Aug 20, 2010
Appl. No.:
12/860037
Inventors:
Michael McManus - Oakdale PA, US

International Classification:
B43L 1/00
US Classification:
434408
Abstract:
A modular, portable writing and projection system having a variable curvature is disclosed. The system uses dry erase boards, chalk or black boards, or other flexible panels having at least one writing surface. The panels have edges for joining to posts. The system combines panels to form a large, modular system for use at meetings, gatherings or other assemblies. The system allows a large number of users to contribute to a presentation, and also allows users to view the presentation. Because the panels are flexible, the system may be curved, allowing more panels to be mounted, used, written on and viewed, within limited space. The panels may be used in either a convex or concave manner, i.e., curved in or curved out, as desired. The resistance of the panels to remaining in a curved state is overcome by feet on the posts and braking or holding devices on the feet.

International Classification:
A47B 23/04
US Classification:
2484471, 248488, 4061101
Abstract:
A modular collaborative panel system intended for use on walls, frames and stands is disclosed. The system uses dry erase boards, chalk or black boards, or other panels having at least one writing surface. The panels have notches or cut-outs on each side so the panels can be mounted to a wall or a frame using pegs. The system combines panels in rows or columns, or both, to form a large, modular system for use at meetings, gatherings or other assemblies. The system allows a large number of users to contribute to a presentation, and also allows users to view the presentation.
