ABSTRACT:
An expandable finger ring or the like having a pair of arcuate expandable sections each pivotally hinged at one end by a clevis-like arrangement to an arcuate mounting portion. One expander section is provided with an extending centrally reduced tongue portion which is formed with a longitudinally directed open slot. The slotted portions transverse opening at the tongues open end being greater than that at the opposite end. The other expander section is formed so as to slidingly engage the first expander by being formed with a central longitudinal recess at its free end to receive the tongue portion. Disposed intermediate the walls of the second expander and extending across the recess is a fixed stud of a diameter slightly larger than the narrowest portion of the slot. The stud rides in the slot so that when the expanders are fully slidingly engaged with each other, the stud will tightly abut and frictionally engage the walls of the slot to thereby releasably lock the expander sections together.
