Releasable panel assembly for window frame or the like

A panel assembly particularly for a door or a window comprising:

• a frame member;
• a panel member composed of a plurality of constituent members at least two of which are arranged adjacent each other, said panel member being thus formed with a generally planar configuration having an upper edge and a lower edge;
• means mounting said panel member on said frame member for movement between a closed position in which said panel member is located to be within a first generally vertical plane, a tilted position at which said panel member is pivoted about said lower edge with said upper edge being spaced away from said frame member, and a laterally offset position at which said panel member is located to lie within a second generally vertical plane parallel to and spaced from said first plane in a direction away from said frame member;
• an angular housing connected to said panel member adjacent said lower edge between at least two of said adjacent constituent members thereof to provide a reinforcing connection tending to strengthen the rigidity of said panel member;
• and
• at least one releasing arm connected between said frame member and said panel member, said releasing arm being arranged to extend between said panel member and said frame member to support said panel member at the lower end thereof when said panel member is in said laterally offset position.
