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.

An opening and closing structure for an umbrella combining automatic and non-automatic modes including an electric mechanism, a cranking mechanism and a clutch structure is described herein. The electric mechanism includes a screw rod, a motor and a first transmission element. The motor is configured to drive rotation of the screw rod, and the first transmission element is mounted at the screw rod. The cranking mechanism includes a second transmission element and a cranking handle. The second transmission element is engaged with the first transmission element, and the second transmission element is connected with the cranking handle via the clutch structure. The invention overturns a conventional method of using an electric umbrella, and provides a manual lifting-and-lowering function under the premise of maintaining a electric lifting-and-lowering function, that is, in case of insufficient or no power supply, the umbrella can be opened and closed through the cranking handle.

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.

A straight-pole sun umbrella hand-cranking device comprises a standing pole and a shell fixed on the standing pole, wherein the shell comprises a first outer shell and a second outer shell. The shell is fixed on one side of the standing pole, and a rope winding wheel is mounted within the first and the second outer shells. The rope winding wheel is connected to a cranking shaft, and the cranking shaft is propelled to rotate through a cranking handle connected with the cranking shaft. An anti-slip mechanism is arranged on the cranking shaft. The anti-slip mechanism comprises a torsion spring, the torsion spring is sleeved on the cranking shaft. The rope winding wheel achieves easy winding or unwinding of the ropes, and the anti-slip performance is improved by the elastic force of the spring. As the aforesaid structure is protected against abrasion, its functional life is significantly prolonged.

A tilting umbrella with a canopy assembly including a lower hub, an upright pole and a tilt mechanism. The tilt mechanism includes an actuator coupled with a lower pole portion and adjusts an upper pole portion from an untitled configuration to a second configuration. The lower hub is disposed at a tilt location between the upper pole portion and the lower pole portion. The lower hub can include an outer portion disposed over the upper pole portion that is pivotable relative to an inner portion disposed over the lower pole portion in the second configuration.

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 snap-in crank mechanism comprising a crank housing mounted out of a column, and a crank having a crank rod with two ends; the crank housing comprises a crank inner housing sleeved outside the column, and a crank outer housing detachably sleeved outside the crank inner housing; the crank inner housing has a left inner housing, a right inner housing and a lower inner housing, the left inner housing and the right inner housing are connected with each other forming a sleeve which is sleeved outside the column and has a crank rod mounting hole at the periphery of the sleeve; the crank outer housing is slidable on the periphery of the sleeve formed by the left inner housing and the right inner housing; the lower inner housing is inserted from the bottom of the crank outer housing, and is located between the crank outer housing and the bottom of the left inner housing and the right inner housing clamping with the left inner housing and the right inner housing; one end of the crank rod is located inside the crank rod mounting hole and is connected to the crank shaft running through the column, while the other end of the crank rod is connected to the crank head. The jacket of the crank head is made of natural rubber. The present invention is simple and reasonable in structure, easy to dissemble and assemble and aesthetic in appearance, and can satisfy the requirement of replacing many types of housings, improve the user’s comfort in use and improve the production quality and the user experience.

The invention discloses a cantilever parasol with reduced maintenance workload. When the reel mechanism requires maintenance, one only needs to detach the reel housing from the inclined rod, without a need to perform a separate disassembly operation to the cord spool assembly or a need to change a connection relationship between the inclined rod and the post, avoiding difficulty in re-assembling the inclined rod. The cantilever parasol includes a post, an inclined rod and a reel mechanism. The reel mechanism includes a reel housing is detachably connected with the inclined rod, and a cord spool assembly is rotatably installed in the reel housing and located on an outer side of the inclined rod. One end of the inclined rod is connected with the post, the inclined rod is provided with a cord hole, and a cord is passed through the cord hole and connected with the cord spool assembly.
