Locking base for tablet stand
First Claim
Patent Images
1. An articulating electronic device stand for supporting an electronic device, said device stand comprising:
- a base having a plate portion for mounting to a support structure and including an upper surface and a generally opposed lower surface and an aperture extending from said upper surface to said lower surface, and a column extending upwardly from the plate portion and circumaxially about the aperture to define a channel through the base along an axis, said column including an annular bevel extending frustoconically outwardly therefrom to define a bevel surface forming an obtuse angle with respect to an outer surface of the column;
an intermediate plate rotatably mounted about said column; and
a radially adjustable collar positioned about said column, said collar having a chamfer that is coordinatable with said annular bevel of said column to reposition said collar with respect to said column, wherein radial contraction of said collar about said column during contact between said chamfer and the bevel surface forces said collar axially downward toward the intermediate plate, the collar thus being capable of applying a first force to the intermediate plate and inducing a reaction force applied from the upper surface of the plate portion of the base to the intermediate plate, wherein the first force and the reaction force resist rotation of the intermediate plate with respect to the base.
