ABSTRACT:
A contact-sensitive display screen panel of a craft unit is protected by a pivotable lid. The lid is rotatably supported by lid pivot attachments that enable the lid to be pivoted between closed and open positions, and to be stably locked as a support member in its fully extended attitude. Lid pin elements extend from opposite ends of a lid pin support element and engage left side and right side hinge assemblies. Each lid pin element has a tab element translatable along the underside of the lid. Each lid pin element is biased by a compression spring into engagement with a capturing slot in an interior bore of a post of a hinge arm element of a respective one of hinge assemblies. To rotate the lid from its open position, to its fully extended position, the craftsperson translate the tab elements against the biasing of compression springs, so that the lid pin element becomes unlocked from a slot in the interior bore of the hinge arm element of a respective hinge assembly. Once rotated to its fully extended position, finger pressure against the tab elements is released and the tab elements are allowed to again be biased by the compression springs, locking the reduced thickness portions of the lid pin elements in slots of the interior bores of the hinge arm elements of the hinge assemblies, so that the lid will be stably retained as a support element in its fully extended position.
