发明名称 Presentation device with automatic extending support
摘要 A display device such as a folder, binder or book includes transparent envelope pages and a support that deploys automatically when the covers of the display device are opened so that the display device can be supported on a horizontal surface by the lower edges of the covers and the deployed support. The deployment is caused by a tensioned elastic cord which also can be used to retain the covers in a closed position.
