Abstract:
1. A rotary supporting base for a display device, comprising: a stationary lower base member having a top surface formed with a ring-supporting region that is confined by an inner periphery and an outer periphery that is concentric with and that surrounds said inner periphery, said lower base member being further formed with an engaging unit on at least one of said inner and outer peripheries; a coupling ring plate disposed on said top surface of said lower base member at said ring-supporting region and rotatable relative to said lower base member about a rotary axis transverse to said top surface of said lower base member, said coupling ring plate having inner and outer peripheral edges, at least one of which is in sliding engagement with said engaging unit to retain rotatably said coupling ring plate on said top surface of said lower base member; a rotatable upper base member disposed on top of said lower base member and coupled to said coupling ring plate for co-rotation therewith relative to said lower base member; and a coupling unit provided on at least one of said coupling ring plate and said upper base member and adapted to engage an upright prop of the display device; wherein said coupling unit includes an outer tube segment extending uprightly from said upper base member, and wherein said coupling unit further includes an inner tube segment extending uprightly from said inner peripheral edge of said coupling ring plate and through said upper base member, said inner and outer tube segments being configured to slidingly retain the upright prop of the display device.
