US 5,826,604 A · Standing umbrella

Abstract

A standing umbrella includes an upright pole, a top affixed to the upper end of the upright pole, a slide member displaceably mounted on the upright pole, at least four tensioning struts having free outer ends and inner ends linked to the slide member at respective pivots, a flexible cover affixed to the tensioning struts, and flexible carrier elements extending between the top and the tensioning struts. Displacement of the slide member towards the lower end of the upright pole moves the tensioning struts into positions in which they almost extend perpendicularly to the upright pole, diametrically opposite ones of the tensioning struts enclosing an angle of less than 180.degree., whereby the umbrella is opened, and displacement of the slide member towards the upper end of the upright pole causes the umbrella to be closed. A flexible member extends between the tensioning struts and is affixed thereto for limiting the opening movement of the tensioning struts.

A standing umbrella comprising

(a) an upright pole having an upper end and a lower end that may be anchored to a support,
(b) a top extending in a horizontal plane and affixed to the upper end of the upright pole,
(c) a slide member displaceable mounted on the upright pole,
(d) at least four tensioning struts having free outer ends and inner ends linked to the slide member at respective pivots,
(e) a flexible cover affixed to the tensioning struts,
(f) flexible carrier elements associated with the tensioning struts and extending between contact points at the top and the tensioning struts,
(1) displacement of the slide member towards the lower end of the upright pole moving the tensioning struts into positions in which they almost extend perpendicularly to the upright pole, diametrically opposite ones of the tensioning struts enclosing an angle of less than 180.degree., whereby the umbrella is opened, and displacement of the slide member towards the upper end of the upright pole causing the umbrella to be closed,
(2) the contact points of the flexible carrier elements at the top having a maximum distance from the pivots of the associated tensioning struts in a horizontal direction whereby the force required for the displacement is reduced, and
(3) diametrically opposite ones of the flexible carrier elements being connected to form a unit extending over the top and being held and guided by the top, and
(g) a flexible member extending between the tensioning struts and affixed thereto for limiting the opening movement of the tensioning struts.
