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 with an adjustable canopy comprises a canopy adjustment device having a transverse rod connector, an upper clutch gear, a lower clutch gear and a handle; and a transverse rod rotation device disposed on the middle of a transverse rod; the front end of a tilted rod is rotatably connected to the transverse rod rotation device; the bottom end of the transverse rod is rotatably connected to a sliding block through the canopy adjustment device. The upper clutch gear is fixedly connected to the transverse rod; the bottom end of the transverse rod connector is rotatably connected to the sliding block; one end of the handle is rotatably connected to the periphery the upper clutch gear which is against the upper surface of the lower clutch gear. The invention has the advantages of simple and reasonable structure, convenient operation, stable and reliable positioning, and can realize the canopy adjustment only by operating the handle.

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).

An umbrella includes an umbrella column having a top portion hingedly fitted with one end of a connecting rod, and the other end of the connecting rod is hingedly fitted with a pull rod. One side of the umbrella column has a chute, an armrest shell is slidably fitted in the chute, one end of the pull rod is hingedly fitted with an upper umbrella tray, and the other end of the pull rod is fixedly connected to a handle base. The rope reel set is used to wind an umbrella rope, and extends into an umbrella tray assembly along the pull rod. The handle base is hingedly fitted with the armrest shell located at an inner side of the umbrella column and provided for fitting with the chute. The armrest shell is movably positioned along the chute.

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.
