摘要

The long carrying case (1) has a handle mounted in the centre on top and is fitted with two end plates (2). These secure hinged struts (7) while a third strut is hinged from a middle setting. The screen is pulled out of the top of the case and is held upright by a telescopic, hinged strut (6). The case has slots in the top and the bottom to extend the struts and screen. The struts are spring loaded to secure in the extended position and the whole structure is lightweight to carry and simple to erect.
