The present invention provides a conveniently open and close sun umbrella, which includes a vertical pole, a connecting rod, an inclined rod, an umbrella frame and an umbrella opening mechanism. The two ends of the connecting rod are respectively hinged on the vertical pole and the inclined rod. The umbrella opening mechanism includes a first pull rope, a movable pulley, a second pull rope and a slide locking piece which is slidably mounted on the vertical pole. One end of the inclined rod is hinged on the slide locking piece, and the other end is hinged on a fixed umbrella disk. One end of the first pull rope is fixed on the movable pulley, and the other end is fixed on the movable umbrella disk. One end of the second pull rope is fixed on the vertical pole, and the other end is fixed on the slide locking piece.

A tilt device for an umbrella is a guide track assembly disposed in one of a first tilt member and a second tilt member. The guide track assembly has a first guide track member and a second guide track member. An enclosed guide track is within the guide track assembly. The guide track assembly is slideably received within the first tilt member. A driver that has an upper portion disposed in the second tilt member and a lower portion. The lower portion is disposed in the enclosed guide track. The enclosed guide track is configured to guide movement of the lower portion of the driver within the first tilt member. Movement of the driver causes the second tilt member to tilt relative to the first tilt member. The guide track assembly includes an open channel forming a part of a cord channel through the tilt device.

A cantilever umbrella including a frame having an upper tray and a lower tray is provided. Two first crossed rods, a transverse rod and a first long rib are articulated to the upper tray. Two second crossed rods and two first short ribs are articulated to the lower tray. One of the two first short ribs is articulated to a middle portion of the transverse rod and the other one is articulated to a middle portion of the first long rib. A middle portion of each second crossed rod is articulated to a middle portion of the first crossed rod on a same side. An end of each first crossed rod is articulated with a short-rib tray which is articulated to a short rib, and an end of each second crossed rod is articulated with a long-rib tray which is articulated to a long rib. The short ribs each has one end articulated to the short-rib tray and another end articulated to a middle portion of one of the long ribs. The upper tray and the two long-rib trays are each disposed with a cap thereon, and a canopy fabric is covered on the long ribs to form three canopies.

A canopy tension system for an umbrella. The umbrella comprises a frame having a pole with a rib assembly at one end, the rib assembly comprising a plurality of ribs an end cap assembly attached to a distal end of each rib, the end cap assembly including a channel with an adjustable depth for receiving the rib; and a canopy attached to the end cap assembly of each rib of the frame. The end cap assemblies are adapted to modify the tension of the canopy to prevent excessive or insufficient tension when the canopy is mounted by adjusting the depth of one or more channels before the distal end of the rib is inserted.

A parasol includes a stand column and an umbrella cover assembly which includes a tilt strut. A sliding block is installed in cooperation with one end of the tilt strut. A chute is disposed on the stand column, and the sliding block is for sliding up and down along the chute. The chute is provided with a shading device. A collecting mechanism is coordinately arranged in the stand column, and includes a drive assembly, a clutch fork assembly and a transmission assembly. The transmission assembly includes a collecting and supporting transmission assembly and an inclination transmission assembly. The drive assembly is able to be in clutch cooperation with the collecting and supporting transmission assembly or the inclination transmission assembly under action of the clutch fork assembly.

A free arm standing parasol comprises a mast, on which an arm with its end of the arm facing towards mast is guided extendably and retractably via a mast slide and is thereby held by a supporting element between the arm and mast while the end of the arm facing away from the mast carries a parasol part with a crown, the parasol part comprising main struts which are radially hinged to the crown and associated supporting struts which are hinged to a corresponding main strut and a parasol slider. The parasol part is connected, via actuating organs, to a drive unit at the mast, a first actuating organ being connected to the mast slide via first deflection rollers for moving the mast slide up and down across a first functional distance, and a second actuating organ being coupled to the actuating organ via an action coupling and being connected to the parasol slider via second deflection rollers for moving the parasol slider across a second functional distance. To improve operability and stability, it is proposed that the second actuating organ be provided with a transmission unit configured in such manner that the first functional distance and the second functional distance have different lengths.

An umbrella for facilitating folding of umbrella surface includes an umbrella surface assembly and a pole assembly that are cooperatively connected to each other. The umbrella surface assembly includes a middle stick, an upper umbrella tray, a lower umbrella tray, a set of first cross rods and a set of second cross rods. The upper umbrella tray is hingedly connected to a first diagonal draw bar, a middle portion of the first diagonal draw bar is hingedly connected to a second diagonal draw bar, and a lower end of the first diagonal draw bar is hingedly connected to a sliding portion. The pole assembly includes an outer pole, an inner telescopic rod slidably connected to the outer pole, a traction device and an elastic element.

A tilt device for an umbrella is a guide track assembly disposed in one of a first tilt member and a second tilt member. The guide track assembly has a first guide track member and a second guide track member. An enclosed guide track is within the guide track assembly. The guide track assembly is slideably received within the first tilt member. A driver that has an upper portion disposed in the second tilt member and a lower portion. The lower portion is disposed in the enclosed guide track. The enclosed guide track is configured to guide movement of the lower portion of the driver within the first tilt member. Movement of the driver causes the second tilt member to tilt relative to the first tilt member. The guide track assembly includes an open channel forming a part of a cord channel through the tilt device.

A weight system for containing fill material for supporting a free-standing object, comprising a container defining an interior chamber adapted to contain the fill material and a closure system. The closure system is arranged to allow the container to be configured in a closed configuration and an open configuration. Fill material is arranged within the interior chamber when the container is in the open configuration.
