Abstract
Two circular rings or discs which are somewhat rotatable with respect to one another. They are connected by a foldable cover which houses a spring inside. The spring, when collapsed, pushes the discs away from each other while the foldable cover is semi-flexible. When the accessory is collapsed, the foldable cover folds over itself, whereas when the accessory is expanded, the foldable cover becomes unfolded with a smaller-circumference center ridge which is less flexible or non-flexible, and situated between two larger circumference areas. Flanges on the inner and outer rings abut each other, keeping the spring collapsed and discs locked into each other in some embodiments. When the rings are rotated with respect to one another, the flanges become unlocked and the spring separates the discs such that one or both of the foldable cover or spring become the limiting factor in how far apart the discs spread from another.
