Description

Automatic multi-fold folding umbrella

The present invention relates to an umbrella, and more particularly to an automatic multi-folding umbrella.

Umbrella is a functional device that provides shelter from rain, snow or sunlight and provides a cool or sheltering effect. The umbrella device comprises a handle member, and the handle member is coupled to a retractable rib mechanism, and the bolster mechanism is coupled with a canopy surface, whereby the umbrella surface can be supported by the rib mechanism Has a shadow effect.

However, in general, the umbrella is designed on the rib design. Because of the convenience of folding, the umbrella surface is usually pulled by the rib and retracted along the handle member. This method is the easiest in designing the mechanism, but it is also Inconvenience in generating certain usage states. For example, in rainy days, the umbrella is originally supported to prevent rain, but when it is recycled, the umbrella surface will be folded back along the handle piece. At this moment, the umbrella surface is still covered with sporadic water, and it will fall along the recycling direction. Caused by trouble, especially when entering the room from the outside, such as entering the car to recover the umbrella surface is most obvious.

In view of the above situation, some manufacturers have developed related anti-receipt products, such as the M508941 patent case, which is a related technology that counters the umbrella surface to avoid raindrops. However, this anti-receiving structure is due to institutional design problems. Can be made into a long umbrella, still can not meet the needs of consumers prefer short umbrella.

Therefore, the purpose of the present invention is to provide a short umbrella and automatically fold the umbrella.

Therefore, the automatic multi-folding umbrella of the present invention comprises a handle member, an rib unit, a driving unit and a shielding cloth. The rib unit is disposed on the handle member, and is mounted on the handle member. a base, a lower mount slidably disposed on the handle member, a main bone assembly coupled to the lower mount, a plurality of first bone assemblies coupled between the middle portion of the main bone assembly and the upper mount, and a plurality a second erect bone assembly coupled to the distal end of the main bone assembly, and a plurality of third erect bone assemblies coupled to the distal end of the second erect bone assembly, the lower mounting seat being slidable when the handle member is slid The rib unit is driven to form an unfolded position and a retracted position. When the stalk unit is extended outward, the rib unit extends outwardly. In the retracted position, the rib unit is centered on the handle member. Recessing inwardly, and the main bone component and the first struts, the second struts, and the third struts are formed to be folded in the direction of movement of the lower mount The state is reversed, and the driving unit drives the rib unit to form an unfolded and collapsed state by elastic action.

The effect of the present invention is that the rib unit is inwardly centered on the handle member, and the main bone assembly and the first struts, the second struts, and the third struts In the state in which the second mounting seat is folded in the direction of movement of the lower mounting seat, the reverse receiving is formed, and in addition to the utility of the existing water collecting, the short umbrella can be made suitable for the public.
