摘要： A flip-chart comprising at least two sheets bound by a linear attachment spine. The spine is positioned at a substantially vertical angle. The sheets are releasably securable to the spine and to optionally to a chart cover by means of support pegs. The sheets are adapted for writing on both sides thereon, and each sheet is removable from the pad.

摘要： A folding presentation pad easel, particularly suited for a classroom or teaching environment, utilizes a support spine and a leg element with additional legs to form a rigid triangular base, a supporting column, and a telescopic support, with pivotal supports therebetween. Superior stability is provided as well as a minimum required floor space to the rear of the easel, a feature which is particularly desirable in a classroom. When the easel is folded it has a set of wheels and a handle in which can be used for mobility.
