A rod of an umbrella is a rod having a tail end and an extension rod having two ends; one end of the extension rod is detachably connected to the tail end of the rod; the rod is a hollow tube in which the extension rod is inserted, a limiting mechanism is located inside the rod for limiting insertion of the extension rod; the extension rod is made of rigid material or elastic material. When in use, the assembly can be completed by inserting the extension rod into the tail end of the rod, so that the rod becomes longer and is very easy to use. In the present invention, the rod is simple and reasonable in structure and easy and quick for operation and assembly, which can greatly increase the shading area, meet the functional requirements of the product, and reduce the packaging and transportation costs.

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 delta-shaped umbrella apparatus for shading or shielding a user from the rain includes a hub configured for receiving a handle. The hub has a plurality of spring receptacles, and a plurality of springs, with each spring having a coiled portion, a lower anchoring portion, and an upper anchoring portion. Each spring receptacle has a spring chamber configured to hold the coiled portion, at least one anchoring hole configured for the lower anchoring portion to be inserted therethrough, and a slot. A plurality of ribs are anchored to the plurality of springs' upper anchoring portions, and each slot is configured to allow the a rib to swing through a predetermined range of motion relative to the hub. The range of motion defines an arc extending from a position substantially parallel to the handle to a position substantially perpendicular to the handle.

This invention proposes a modern umbrella, which consists of ribs, nests, shaft and canopy. The ribs have long ribs and supporting ribs, and the nests are composed of upper nest and lower nest, with the lower nest composed of several disks from up to down. Between two neighboring disks is a connecting tube, and the disks mentioned above have several mounting notches, which are not arranged in order. One end of supporting rib is articulated to mounting notch, and the other end to long rib. With regard to two neighboring disks, the distance from the joint between supporting rib connected with upper disk and long rib to upper nest is no greater than the distance from the joint between supporting rib connected with lower disk and long rib to upper nest. The canopy clings to long ribs to shape various concave-convex surfaces. Through layers of disks at the lower nest, the canopy clinging to ribs shows the staggered arrangement of concave-convex surfaces to improve water diversion effects, air flow dispersion ability and the ability to withstand wind. Meanwhile, such design can achieve the aim of folding the umbrella safely.

This application provides an umbrella including an umbrella frame, supporting members, rotating shafts, fixing members, and umbrella surfaces. The umbrella surfaces are installed at the umbrella frame through connections of the supporting members and the fixing members so as to form a layered structure with a beautiful appearance and good breathability and ventilation. Each of the supporting members has installation arms which can be directly installed at the umbrella rib through the rotating shaft. Each of the supporting members has a first supporting surface and a second supporting surface cooperating with the umbrella rib to achieve limitation, which can limit a rotation range of the supporting members and reduce members such as a bracket, a spring and so on. The structure is simpler, and the assembly is very convenient.
