US Patent 10239642 Hinge and lock mechanism for roll-out solar array

A roll-out solar array includes a first mandrel having first and second ends and a second mandrel having first and second ends. A hinge extends between the first and second mandrels, such that the roll-out solar array can transition between a stowed position where the mandrels are in a substantially parallel configuration and a deployed position where the mandrels are in a series configuration. A latch may be provided to lock the roll-out solar array in the stowed configuration.
