Abstract: A channel bar assembly is provided for use with a modular display system. The modular display system can have a display frame that is made up of a plurality of legs that are coupled to a plurality of hubs. The channel bar assembly includes a first channel bar and a second channel bar, each channel bar having a first end and a second end, and a hub connector having a first end hingedly coupled to the second end of the first channel bar, and a second end hingedly coupled to the first end of the second channel bar. The hub connector is connected to one of the plurality of hubs.

Abstract: A storage case has a plurality of walls surrounding an internal compartment, a door provided in a front wall for providing access to the internal compartment, a top panel for covering the internal compartment, and a removable table top assembly resting on the top panel. The table top assembly has a plurality of table top panels that are removably coupled together to form the table top assembly, and which are adapted to be stored in the internal compartment. The storage case further includes a base panel between the plurality of walls, and a set of wheels provided adjacent the base panel. A shelf may be provided in the internal compartment when the storage case is used as a combined storage cabinet and table top. The storage case is especially adapted for use in storing components are that used to assemble a modular display system.

Abstract: A system is disclosed for connecting a first panel to a second panel in a manner which aligns the first and second panels at the same vertical level with respect to each other. The first panel has a female connecting member provided along its vertical edge, and a channel disposed transverse to the vertical edge. The second panel has a male connecting member provided along its vertical edge, and a slot provided in the male connecting member. A sliding pin block is retained for sliding movement inside the channel of the first panel, the sliding pin block having a pin normally biased to extend through the female connecting member. The pin is fitted inside the slot of the male connecting member when the first and second panels are connected along their vertical edges to align the first and second panels at the same vertical level with respect to each other.
