A wind-resistant umbrella including a canopy attached to an upper end of a pole member, flexible ribs, and multiple load sensitive connectors (LSCs) is provided. The flexible ribs flex inwardly at a wind speed of more than about 10 miles per hour (mph) to preclude wind from traveling under the canopy. The LSCs detachably couple an upper canopy section to a lower canopy section of the canopy. The upper canopy section partially overlaps the lower canopy section along the LSCs. Upon impact from a wind gust that exceeds a speed of more than about 20 mph, at least one of the LSCs detach to allow wind to flow freely through one or more vents created between the upper and lower canopy sections, while providing warnings to a user, and to preclude wind-induced tilting and lifting actions on the wind-resistant umbrella, thereby precluding dislodgment thereof from an anchoring location.

Disclosed herein are retractable umbrella frame devices comprising a base body structure at least partially surrounding a central axis structure. The central axis structure can be connected to a skeletal frame structure comprising a plurality of arms having a first end connected to the central axis structure and a second free end. The plurality of arms can be moveably connected to the central axis structure, such that the arms can be retracted into or extended from the base body structure. In some embodiments, the base body structure comprises open portions along its length. In some embodiments, the retractable umbrella frame devices further comprise one or more secondary support structures at least partially surrounding the base body structure. In some embodiments, the retractable umbrella frame devices can further comprise guide structures connected to the one or more secondary support structures and the arms of the skeletal frame structure.

An umbrella including a support shaft, a plurality of ribs, a rotatable cam assembly, and a canopy. Each rib of the plurality of ribs has a proximal end portion and a distal end portion. The proximal end portion is pivotably attached to an upper portion of the support shaft to pivot the rib between an open position and a closed position. The rotatable cam assembly includes a cam configured to rotate about a longitudinal axis of the support shaft. The cam is engaged with each rib of the plurality of ribs such that (i) each rib moves in a direction from the closed position to the open position when the cam rotates in a first direction and (ii) each rib moves in a direction from the open position to the closed position when the cam rotates in a second direction, the second direction being opposite the first direction.

An umbrella assembly is described in which a spring assisted movement of a knob away from or toward an umbrella handle respectively deploys or retracts a canopy and a plurality of support ribs. In the deployed position, each rib curves and keeps the canopy under tension. Elastic potential energy of a spring located within a body interior space deploys or retracts the ribs and canopy out of or into the body interior space, respectively.

The invention is a shading structure (10) having an open state and a closed state and comprising a canopy (12), wherein the canopy (12) is affixed to further components of the shading structure (10) at at least two attachment places (18), wherein the two attachment places (18) define an axis of rotation (21), and at least two stiffening sections (14) arranged along a periphery of the canopy (12), wherein adjacent stiffening sections (14) are coupled to each other by a respective articulating member (16), and wherein the canopy (12) is stretched in the open state of the shading structure (10) by means of the stiffening sections (14) coupled to each other by the articulating member(s) (16).

The shading structure is characterised in that in the open state of the shading structure (10) the stiffening sections (14) are skew with respect to the axis of rotation (21), and in the closed state of the shading structure (10) the stiffening sections (14) extend in the direction of the axis of rotation (21), and the canopy (12) is rolled up around the axis of rotation (21).

A hand-push umbrella has a column, an upper nest at the top of the column, a lower nest on the column, a plurality of long rods having an upper end mounted on the upper nest and a plurality of first short rods having a lower end mounted on the lower nest and an upper end hinged to the middle portion of the long rod; a first retainer ring sleeved on the column above the lower nest and fixed with the column, a handle is connected to the bottom of the lower nest, and a handle control mechanism is disposed inside the lower nest. The umbrella is simple and can be easily unfolded and folded. A tray and a plurality of second short stretchers greatly strengthen the support to the canopy and improve the stability of the structure.
