RELEASABLE RETAINING MEANS FOR A CLOSURE ELEMENT

摘要

A releasable retaining means for mounting on the inside of an outward opening closure element movable to open and close an opening. First and second mounting means (13 and 14) are respectively mountable on the closure element (11) and opening surround (12) with a stay (15) slidably and pivotably coupled to the second mounting means (14). Stay (15) is pivotably couplable by engagement means (22) to the first mounting means (13) and releasable therefrom by sliding stay (15) relative to mounting means (14) but only when the closure element is closed. Recoupling means (16, 24) automatically cause the engagement means (22) to couple to said first mounting means (13) when the closure (11) is moved into the closed position. The retaining means thus prevents closure element (11) from opening more than a predetermined amount unless the stay (15) is released from the first mounting means (13) prior to opening the closure element (11). If stay (15) is released it becomes automatically recoupled on closing the closure element.
