Puzzle ring
First Claim
1. A toy puzzle comprising, a first collapsible four-link parallel linkage arranged in a pantograph configuration having all links thereof pivotal, the four links having pivot points at opposite end portions thereof, means pivotally connecting said four links at said pivot points, a first of the four links having a second link and a third link pivotally connected thereto on a same inner side of opposite end portions thereof and a fourth link opposite said first link having said second link and said third link pivotally connected thereto on a same outer side of opposite end portions thereof, a second collapsible four-link parallel linkage arranged in a pantograph configuration having all links thereof pivotally connected and constructed similarly to said first collapsible four-link parallel linkage, four connecting links each pivotally connecting corresponding pairs of pivot points of said first and second four-link parallel linkages, two of said four connecting links each having an end portion pivotally connected at a separate one of said pivot points on an outer side of said first link of said first four-link parallel linkage and each having an opposite end portion pivotally connected at one of separate points on an inner side of the first link of the second four-link parallel linkage and inwardly of links connected thereto, two others of said four connecting links each having an end portion pivotally connected at a separate one of said pivot points on an inner side of the fourth link of said first four-link parallel linkage and each having an opposite end pivotally connected at a separate one of the pivot points on an outer side of the corresponding fourth link of the second four-link parallel linkage outwardly of links pivotally connected thereto, and all of said links having a same length and each being elongated, flat and flexible for deformation thereof arcuately along the length and thickness dimensions thereof.
