US Patent 10548391 Tool pouch with bi-stable hinged closures

A tool pouch, tool bag, utility pouch, or similar, comprising one or more individual tool pouches, used by tradesmen in difficult and/or dangerous environments where it would be convenient and preferred for safety reasons for the tool pouches to remain closed or remain open without manual intervention. Tool pouches within a tool pouch are configured with bi-stable hinges in which an over-center cam-spring arrangement alternatively maintains either a fully-closed or a fully-open configuration until an intentional opening or closing action by a user. Individual tool pouches within a tool pouch may be opened or closed independently of the open or closed positions of other tool pouches.
