An umbrella drawing-in by winding includes an umbrella fabric, a frame, a shaft and retracting assemblies. The frame includes a notch, a runner and a rib support set. A top end of the rib support set is secured at a top end of the shaft via the notch. A bottom end of the rib support set is secured on the shaft via the runner. The umbrella fabric has folds and is secured on the frame. The retracting assemblies are secured on one side of the folds.

An umbrella assembly can be assembled using L-shaped elongate members pivotably coupled with upper and lower hubs for supporting and actuating an umbrella cover. The L-shaped elongate members can be pivotably coupled together and paired such that a lateral portion of each of the elongate members extends opposite the other lateral portion within the pair and pivotably coupled with one of the upper hub and the lower hub. The lateral portions pivotably coupled within rib-receiving slots corresponding to one of the upper hub and the lower hub and secured within the rib-receiving slots by one of an upper hub cap and a lower hub cap.

The present invention relates to an easily assembled and disassembled shade-providing structure, such as may be mounted to a playground assembly. The shade-providing structure comprises an outer frame defining an interior space and a canopy that may be positioned in that interior space. The canopy has one or more rods around its periphery, such as may be inserted through one or more pockets in the canopy fabric. Each of the outer frame and the rod(s) has a set of apertures configured to receive a locking fastener and a set of apertures configured to receive a jack screw or similar tensioning device. Accordingly, to assembly the structure, one or more jack screws can be used to provide the canopy with a desired tension and then locking fasteners can be used to secure the canopy to the outer frame.

An umbrella frame bending structure for two-fold inverted umbrella includes an umbrella shaft assembly, an umbrella frame and bending devices. The bending devices are arranged on the umbrella frame such that when the main ribs and auxiliary ribs of the umbrella frame are opened, the auxiliary ribs limit the opening distance of the main ribs, causing the main ribs to curve. The umbrella frame bending structure has the advantages of low cost, simple structure and ease of installation.

The disclosure is directed at an umbrella including a canopy having a set of canopy portions; and a frame portion comprising a shaft portion; a sliding collar assembly coupled to the shaft portion and sliding along the shaft portion; and a set of ribs, each of the independent ribs attached to one of the set of canopy portions and to the sliding collar assembly, where each of the set of ribs move independently of each other when a high wind force is experienced by one of the canopy portions.

The parasol includes a base having a pole, a head secured to one end of the pole and having a canvas filtering at least part of the rays of the sun, and a structure supporting the canvas and being deformable between an open configuration with the canvas outstretched, and a folded configuration with the canvas folded. The support structure includes a hoop or peripheral hoop, which is closed in on itself and lies in a plane in the open configuration. The parasol includes the canvas attached inside the peripheral hoop such that the canvas is stretched out inside the peripheral hoop in the open configuration.

A hat-umbrella comprises a circular frame with a shade attached to a plurality of extendable and retractable radial supports that form an umbrella around the circular frame. When expanded, the radial supports extend away from the circular frame, thus a large shade is formed. When retracted, the radial supports collapses around the circular frame and the shade is folded.
