Lockable hatch with several panels, and method for producing such a hatch by converting an existing hatch

摘要

Fastening means (10) are fastened permanently to the frame, and complementary fastening means (12, 13) are fastened permanently to each of the panels and are designed to interact respectively with the fastening means of the frame and of at least one adjacent panel. Several panels can slide on the frame along the latter parallel to at least one of the said sides between a position in which each panel is free relative to the frame and to at least one adjacent panel already fitted and a locked position in which the complementary fastening means of each of the panels are respectively in engagement with the corresponding fastening means of the frame and of at least one adjacent panel. Specific fastening means are designed to interact with moving elements for locking a panel designed to be fitted last with respect to the frame and with respect to at least one adjacent panel. <IMAGE>
