The panel can be slid into an open position where it can be rotated, the panel being in contact with fasteners (2, 3) for a top and bottom rail (1) in this position. At least one of the fasteners (2) includes a first locking part (2a), and in the opening position the second fastener (3) acts as a spring-loaded second locking part extending parallel to the panel rotation shaft (2e). Each locking part has a round cavity (2b), and the second locking part has a complimentary male profile (3b). As the panel is slid into the opening position the first locking part moves the second locking part and ensures the male profile becomes fixed inside the corresponding female cavity. Profiles (2d) associated with the two locking parts are used to ensure the male and female parts remain engaged when the panel is swung out, so that the panel remains fixed in the open position. |
