A panel system is provided in which adjacent panels are removably joined at their edges. The system includes the following components: a pair of substantially identical clips, each of which is affixed to an edge of a panel, each clip including a base portion and a body portion extending upwardly from the base portion in a generally perpendicular disposition with respect to the base portion. At least two linear members extend in an inward direction away from the body portion away from the base. These members define slots which also extend parallel to the base. These body further includes a substantially flat, outwardly facing portion on the side of the body opposite the members. Each of the panel edges defines a channel having flat walls which extend parallel to their respective panel. The channel walls extend from a channel bottom upwardly to the panel edge. The base of each clip is designed to be affixed to its respective channel at the bottom. The configuration and height of the clips are such that at least one of the linear members and at least one of the slots is disposed within the channel when the base is mounted in place, and at least one of the linear members and at least one of the slots extends out of the channel beyond or above the edge of the panel. The flat, outwardly facing portion of the body of each clip extends in substantial contact with its adjacent channel wall when the clip is affixed in the channel. The clips and their associated panels can be mounted to one another by sliding the linear members of one of the clips into complementary slots in the other clips, with the channel walls preventing the two clips from being disengaged. Once it is desired to disassemble the panels they are vertically slid apart. Because the normal loading of a panel is not normally in that lengthwise direction, inadvertent dislodgement is highly unlikely.

A modular display panel and edge latching system therefor which employs concealed movable latching mechanism that can be actuated between adjacent panels set up, for example, on a floor to lock the panels into vertical alignment and against any tendency of floor unevenness to cause adjacent panels to become misaligned vertically. The components in the latching mechanism which create vertical position locking are actuated by the insertion of actuators typically carried as downward projections on other panels which rest on top of directly floor supported, underlying panels.

A portable display formed of a plurality of assembleable panels having wire management permitting concealment of wire for powering accessories within the junctures between panels. In a preferred embodiment, the panel edges have edge portions formed with outwardly facing channels defining or including wire conduits. Panel connector portions, either of the sliding type, or the peg or plug-in type secure the panels together to form the display. In a preferred embodiment, each panel has four corners each with corner components that engage with the edge portions, preferably by insertion into receiving openings in said edge portions. Said corner components having a receptacle exposed at each corner to permit either connection with plug-in components, for example, panel connectors for vertical stacking of panels or with accessory brackets. The panel connectors having a U-shaped portion consistent with the wire management characteristics of the invention that that allows the wire conduit to extend through said connectors. Thus attachment of electric powered accessories with concealed power lines is provided.
