Abstract: An updatable and lockable flip chart holder that can clip into the rail strip or channel of a shelf or fasten to a display at a retail store. The flip chart holder allows manufacturers or promoters of products that are sold at retail to create consumer, educational, or promotional flip charts that can easily and economically be updated by opening rings. The lockable flip chart has a panel, and attached to the panel is a ring system with each ring having two ring halves and hinged leaves connected to each other and attached to each ring half respectively. A locking mechanism on the ring system presses against the leaves to prevent the ring halves from opening. Locking the rings also provides security so consumers cannot take the pages out of the flip chart holder.

Abstract: A binding assembly includes first and second sheet retaining members which are releasably attached to a base member by first and second latching mechanisms. The sheet retaining members include a pair of side members which support a pair of pins and tubes onto which sheets of paper or other materials are placed. Each of the side members includes an engaging rod which is receivable in a channel provided in the base member to retain the sheet retaining members to the base member. Each of the latching mechanisms are independently pivotable about an axis perpendicular to the pins and tubes from a retaining position where the sheet retaining members are constrained to the base member, to a releasing position where the sheet retaining members may be detached from the base member.

Abstract: A binder for storage of sheet materials, particularly large sheet materials, such as maps, blueprints and the like, in a flat configuration. An elongated frame element, which supports the sheet materials along a marginal edge in a hanging orientation, is provided with a pivoting hand grip mounted on the frame and movable between vertical and horizontal orientations. The hand grip, of which there may be more than one, enables the binder and its contents to be conveniently removed from a storage rack and re-positioned for use.

Abstract: A binding mechanism is provided having a plurality of carriers, each supporting a pair of engaging rods, slidably mounted lengthwise of a spine. A pinion member interfacing a plate with gear teeth mounted to one of the pair of engaging rods allows for movement of one of each of the pairs of engaging rods simultaneously.
