发明名称 Lampshade frame with segmented ribs to achieve both an erect and collapsed state
摘要 There is provided a lampshade frame that shifts between an erect, use configuration and a collapsed configuration for shipping, packaging and/or storage. The frame includes an upper hoop and a lower hoop with segmented ribs extending between the hoops. Each of the segmented ribs includes at least two segments that are interconnected by a sleeve that allows them to shift between an extended position, where the length of the rib is maximized for erecting the lampshade, and a retraced state, where the length of the rib is shortened for collapsing the lampshade. The sleeve also locks the ribs in the extended state against unintentional collapse of the lampshade frame.
