Universal hub and plate assembly for attaching multiple graphic systems on a single frame

A universal hub assembly for a portable display frame, the portable display frame including a plurality of elongate arms pivotably coupled to the universal hub assembly configured to enable the mounting of at least one stretched fabric panel and/or a frame assembly, the universal hub assembly comprising:

• a hub component having an outer surface, an inner surface, and a plurality of side surfaces, the inner surface and the plurality of side surfaces defining a plurality of grooves shaped and sized to accommodate ends of the plurality of elongate arms and configured for pivotably coupling an elongate arm to the hub component, the hub component further defining a through bore passing from the outer surface to the inner surface;
• a rigid threaded insert housed within the through bore;
• and
• a threaded post having a threaded portion and a button head, the threaded portion being configured to threadedly couple to the threaded insert such that button head extends from the outer surface of the hub component, the button shaft being configured to operably couple to at least one of a stretched fabric panel or a frame assembly,
• wherein the outer surface of the hub component includes structure defining a keyed boss protruding therefrom, and wherein the through bore extends through the keyed boss to the inner surface;
• a faceplate having an outer surface and an inner surface, the inner surface being shaped and sized to mate with the keyed boss such that the faceplate couples to the outer surface of the hub component and the keyed boss nests within the inner surface of the faceplate, and wherein the faceplate includes structure defining a through bore that, when coupled to the hub component, the through bore of the faceplate is aligned with the through bore of the hub component,
• wherein an inner sidewall of the through bore of the faceplate is threaded, and wherein, when assembled, the threaded post threadedly engages the inner sidewall of the through bore and the threaded insert housed within the through bore of the hub component, and the button head extends from the outer surface of the faceplate.
