Bi-Stable Support Fixture for Addition of Pendants to Jewelry Chains

摘要

A support fixture is provided for holding chain to facilitate addition of pendants thereto. The fixture comprises a polymeric base and a pair of inter-nesting uprights pivotably mounted therein at opposed ends of the base. The uprights can be stably disposed in either an upright usage configuration or a nested horizontal configuration. The base has an upper surface with a generally planar periphery and a major centrally located recess formed therein. The upper extremity of each upright is provided with a retention pin and a padded clamp. Each clamp is formed from a “7” shaped portion and an inverted “L”-shaped arm pivotably joined thereto, with horizontal portions of the “L” shaped arm and the “7” shaped portion defining the jaws of the clamp. A resilient spring is disposed between a vertical leg of the “7” shaped portion and a vertical leg of the inverted “L” shaped arm.
