Horizontal shutting multi-folding umbrella hand pulling opening or closing structure

Abstract

The present invention relates to a horizontal fastened folding umbrella hand-pulling opening and back-drawing structure. Said structure includes a lower nest and a pulling ring, on the lower nest a fastening structure is set, the pulling ring is cover-tied on the lower nest. The described fastening structure is a wane, the cross-section of said wane is made into the form of inwards-curved ar, said wane is horizontally placed on the lower nest, the movement direction of said wane is perpendicular to the axle centre of said lower nest. The above-mentioned structure can adopt simple hand-operated push-pulling mode to implement opening and back-drawing control of said umbrella.

Description

technical field [0001] The present invention relates to an umbrella, specifically an umbrella opening and closing control structure, which enables people to achieve the effect of opening and closing the umbrella by pushing and pulling it by hand. Background technique [0002] Multi-folding umbrellas usually use a control button on the lower nest. There is a seesaw in the button. The seesaw is held by a spring. The seesaw acts on the middle stick. When the umbrella is opened, the seesaw is fastened to the locking groove of the middle stick. , so that the lower nest is positioned and the umbrella surface is stretched; when the umbrella is retracted, press the button to release the locking of the seesaw on the center rod, and the umbrella can be retracted. This method is realized through the control of the button, and the button is set in a part of the nest under the umbrella. Whether it is intentional or unintentional during use, the umbrella surface will rotate, causing the p...

Problems solved by technology

This method is realized through the control of the button, and the button is set in a part of the nest under the umbrella. Whether it is intentional or unintentional during use, the umbrella surface will rotate, causing the position of the button to be not fixed. Umbrellas need to manually find the position of the button to achieve control, which is not convenient for operation

[0003] Therefore, patent application 0229267.0 (name: umbrella nest positioning device) proposes a new control mechanism for opening and closing umbrellas. This mechanism is to improve the lower nest of the umbrella, except for the original umbrella opening control mechanism. The control method is changed to a pull ring combined with a buckle. The buckle is set on the upper nest, protrudes downward, and fastens with the lower nest. The release of the buckle is controlled by the pull ring. This structure needs to be improved for the upper and lower nests. Complicated structure, impractical

[0004] Moreover, the upper nest parts protruding downward will expand the space occupied by the lower nest, resulting in an increase in the volume after the umbrella is retracted. At the same time, the form of the upper and lower fastening needs to be provided with guide grooves, otherwise it will not be able to achieve accurate buckling due to the left and right offsets.
