One end of the flexible traction member (6) is securely mounted on the slider (3), and the other end is securely mounted on a counterweight member (7). When the umbrella is to be closed, the slider (3) is moved downward along the support tube (5), and the sliding device pulls the flexible traction member (6) to lift the counterweight member (7) upwards. When an upper end of the counterweight member (7) is brought into contact with a lower end of the guide tube (4), the guide tube (4) is pushed upwards by the counterweight member (7), and the upper hub (1) is lifted. At the same time, the ribs (9a) pivotably connected to the upper hub (1) are driven to be lifted. In a second embodiment, a free pulley system is additionally provided for labor-saving purposes. The pulley system is composed of an additional push rod (11) telescopically disposed in the support tube (5) and the guide tube (4), and operable through a device such as an additional traction member. On closing of the umbrella, the push rod (11) is driven to move by the counterweight member (7), and the guide tube (4) is pushed upwards by the push rod (11).
Umbrella assemblies described herein are configured to retract and extend, tilt side to side, and open and close. In some embodiments, the umbrella assembly can include a cantilevered beam. The umbrella assembly can further include a tilt mechanism operable to rotate the canopy frame. The umbrella assembly can include a clutch mechanism fixed to the cantilevered beam. The umbrella assembly can also include an integrated mechanism to both open and close the canopy frame and raise and lower the cantilevered beam.

The first clamping arm and the second clamping arm (4, 5) have a first boss and a second boss (41, 51) respectively. The first boss and the second boss are disposed opposite to each other. The number of the short rib fixing holes (3) is not less than 2, and the short rib fixing holes (3) are arranged at intervals in the length direction of the short rib insertion portion. Both the first clamping arm and the second clamping arm (4, 5) are of an arc shape or a corner shape. The middle disk of the sunshade is formed by combining a first portion and a second portion (6, 7). The first portion (6) comprises a first end and a second end (61, 62) connected to each other. The second end (62) has the first clamping arm (4). The second portion (7) comprises a third end and a fourth end (71, 72) connected to each other. The fourth end (72) has the second clamping arm (5). The first end and the third end (61, 71) are in contact with each other to form the short rib insertion portion. The middle disk of the sunshade is of a simple structure and is simple to be assembled.
A slide block mechanism of a standing post of a sunshade comprises a standing post (1), a slide block (2), a slide block handle (3), an elastic component (4), a plate buckle (5), and a positioning pin (6). A connection portion (31) is disposed on the slide block handle (3). The standing post (1) is provided with a positioning hole (11) axially. The slide block (2) is disposed on the standing post (1) along an axial direction of the standing post (1) in a sliding manner. The slide block handle (3) is disposed on the slide block (2). The plate buckle (5) is disposed on the slide block handle (3) in a rotatable manner. The positioning pin (6) is disposed on the plate buckle (5) and passes through the slide block (2) and the positioning hole (11). The elastic component (4) is located between the positioning hole (11) and the slide block (2) and butts against the positioning pin (6) and the slide block (2) separately.
