US Classification:

135 33C

Abstract:

Folding umbrellas which close into a compact condition, for convenience in storage and portability are, of course, well known. To such umbrella, having the characterizing closing mode in which lower rib portions fold bodily against upper rib portions, there are provided, in one embodiment, cooperating closure panels which move towards each other from opposite sides against the bodily folded ribs and are joined to each other, by snaps, zipper, or the like, so as to effectively serve as an integral cover for the umbrella and, in another embodiment, a sock-like tube which is pulled over the folded-closed umbrella thereby serving as a closure for same.

Inventors:

Joseph DeMarco - New York NY

International Classification:

A45B 1906
A45B 1100

US Classification:

135 26

Abstract:

A folding umbrella, particularly useful as a beach umbrella, in which circumferentially spaced outer ribs are slidably disposed on cooperating struts as the undersupport of the fabric cover, and in one extreme position of the slides, the umbrella opens to a radius of approximately 42 inches, and in an opposite slide position, the umbrella closes to a radius of approximately 32 inches, the 10 inch difference being the result of slide movement of the end of the rib along a strut which produces an internal fold in a central location of the fabric cover and thus diminishes its size accordingly.

Inventors:

Joseph H. DeMarco - New York NY

International Classification:

A45B 1910

US Classification:

135 25R

Abstract:

A folding umbrella of the type in which a lower section closes upon an upper section, as both these sections close upon the umbrella rod, and wherein this closing movement is automatically achieved, i. e. is the result of articulating or pivotal movement of the umbrella ribs, rather than being movement that must be manually imparted.
