ABSTRACT:
An emergency umbrella includes a hollow, tubular handle; a hub formed of an inverted cup-like section slidably contained in the handle between an open position at the upper end of the handle and a stored position at the lower end of the handle, the hub also including a piston secured to the inverted cup-like section; a sleeve slidably mounted on the hub between an upper position and a lower position, the sleeve including a central section slidably mounted on the hub and radially directed strut locking sections hingedly connected to the central section; a plurality of struts connected to the strut locking sections, each strut movable between an upright position substantially parallel to the longitudinal axis of the handle and a radial position substantially radially outward from the longitudinal axis; and a web of flexible, water-resistant material connected to the struts, such that opening and closing of the struts is accomplished by a snap action of the handle, whereupon the sleeve slides on the piston of the hub.
