Description

Technical area

[0001] The present invention relates to the technical field of outdoor parasols, in particular to an outdoor parasol with a novel lifting mechanism for opening and closing. State of the art

[0002] The Roman umbrella, also known as a 360° rotating umbrella, is one of the most powerful outdoor umbrellas, capable of rotating horizontally in a circle or vertically by 90°. A Roman parasol is the most creative and casual way to shade from the sun on the Chinese market. Compared to other umbrellas, Roman umbrellas provide more shade and are easier to use.

[0003] A typical Roman umbrella consists of a riser and a canopy assembly, which includes a center pole, a cross pole, an upper canopy, a lower canopy, and a canopy. When the umbrella is closed, the height of the upper canopy remains unchanged, and the cross pole folds by moving the lower canopy upwards, thereby achieving the function of closing the umbrella. In the currently sold parasols, due to the large surface area of ​​the umbrella, the canopy bone is close to the ground when the umbrella is closed, and it is easy to touch the table under the umbrella and the objects on the table when opening and closing the umbrella. If the edge of the umbrella is too high, it will not provide shade.

[0004] A Roman umbrella that facilitates canopy contraction, as described in publication number CN109619782A, comprises a matingly connected canopy unit and a riser tube assembly, the canopy unit comprising a matingly connected center pole, an upper canopy disc, a lower canopy disc, a set of first cross poles, and a set of second cross poles, the upper canopy disc being hinged to a first inclined tension rod, the middle part of the first inclined tension rod being hinged to a second inclined tension rod, and the lower end of the first inclined tension rod being hinged to a sliding portion; the riser tube assembly comprising an outer riser tube, an inner telescopic pole, a tensioning device, and an elastic member.The present invention is reasonably designed and compact, and the structure of the present invention allows the upper screen panel to be positioned upward during the closing operation, which in turn raises the height of the entire screen surface unit, so that it is not easy to touch the table under the screen and the objects on the table. In addition, this structure eliminates the need to raise the edge of the screen, so that it is not too high, resulting in poor shading.

[0005] In the above structure, the umbrella column needs to cooperate with the internal multi-stage rollers for sliding traction, which makes the overall structure relatively more complex. Content of the invention

[0051] The manual drive section 620 comprises a hand rocker part 623, a drive gear seat 621 and a drive clutch 622, wherein the manual drive section 620 serves to drive the rotary shaft 610 in a rotating operation so that the telescopic sleeve assembly 700 can be telescoped or retracted along the central screw 800;Among them, the drive gear seat 621 and the drive clutch 622 are common components in the prior art. The hand rocker part 623 is usually a handle, and the user shakes the handle to drive the drive gear seat 621. With the power input of the rocker handle, the power output is realized through the gear seat 621 to the drive clutch 622. The upper part of the drive clutch 622 is connected to the bottom of the rotary shaft 610, so that the rotary shaft 610 can be driven to achieve rotation, to assist the movable opening and closing mechanism, and to achieve the opening and closing or position adjustment of the umbrella frame 200.

[0052] The lower end of the central screw 800 typically extends into the inner cavity of the rotary shaft 610 and is fitted into the inner cavity of the rotary shaft 610 by means of a screw bearing 810, wherein the screw bearing 810 can achieve an up and down movement along the inner cavity of the rotary shaft 610, thereby facilitating the up and down lifting and moving of the lifting umbrella column assembly in connection with the implementation of Example 1.

[0053] In combination with the above, in one of the preferred embodiments, the drive mechanism may be selected to coexist with the electric drive mechanism 500 and the manual drive mechanism 600 or to be accompanied by a separate electric drive mechanism or a separate manual drive mechanism.

[0054] Preferably, the electric drive mechanism is used to rotate the central screw, thereby causing the movable base to perform a positioning movement and completing the drive of the remaining components; and the manual drive mechanism is used to rotate the integral telescopic sleeve assembly by means of a rotary shaft, thereby causing the movable base to rotate. At this time, the central screw is at rest, and the movable base can rotate and then move up and down along the central screw.

[0055] The present invention uses a movable opening and closing mechanism in combination with a drive that can be electrically and / or manually driven to improve the ease of opening and closing the umbrella and the comfort of use. In particular, the movable opening and closing mechanism is optimized to utilize the cooperation between the central screw and the telescopic sleeve assembly, which can move the boom base in a convenient manner, so that the umbrella frame can be conveniently opened and closed.

[0056] The above embodiments are only a preferred embodiment of the present invention and do not constitute a limitation of the invention in any way, and any simple modifications, equivalent changes, or modifications made to the above embodiments in accordance with the technical principles of the present invention are still within the scope of the technical embodiments of the present invention.
