ABSTRACT:
An umbrella with an oval canopy comprising a center pole (1), a plurality of long main ribs (12), and a plurality of short main ribs (31). The center pole (1) consists of upper and lower poles (1') (1") slidably fitted. Each long main rib (12) consists of a proximal long main rib (16) and a long distal rib (19) slidably fitted to the proximal long main rib (16) through a slide member (18). Each short main rib (31) consists of a proximal short main rib (35) and a short distal rib (38) slidably fitted to the proximal short main rib (35) through a movable member (37). When opened, the canopy automatically assumes an oval form or substantially oval form, and when closed, the distal ends of the main ribs automatically lie on the same plane, and when compressed, the total length of the closed umbrella is considerably shortened.
