DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1˜6 disclose a rib structure of an inverse folding umbrella, which comprises: an umbrella pole component (1) and a plurality of umbrella rib components (2); said umbrella pole component (1) includes an umbrella pole (11), a first umbrella receptacle (12) and a second umbrella receptacle (13), said first and second umbrella receptacles (12, 13) are respectively sleeved on the umbrella pole (11); said umbrella rib component (2) includes a first bar (21), a second bar (22), a third bar (23) and a fourth bar (24), one end of the first bar (21) is pivoted on the first umbrella receptacle (12), the other end is provided with a connecting piece (25), one end of the second bar (22) is pivoted on the connecting piece (25), the other end is configured with tail bead (3), and the second bar (22) is sleeved with a first pivot connecting base (26), one end of the third bar (23) is pivoted on the second umbrella receptacle (13), the other end is pivoted on the second pivot connecting base (27) sleeved on the first bar (21), and the body of the third bar (23) is provided with a third pivot connecting base (28), a movable pivot, connecting base (29) and a positioning piece (291) to limit the movable pivot connecting base (29), one end of the fourth bar (24) is pivoted on the movable pivot connecting base (29), the other end is pivoted on the first pivot connecting base (26), and the body of the fourth bar (24) is provided with a guiding piece (4) that is pivoted on the connecting piece (25), between the guiding piece (4) and the first bar (21), a flexible spring (5) is configured to connect them together.

More specifically, through the design of the lovable pivot connecting base (29) on the third bar (23), the third bar (23) and the fourth bar (24) are connected to each other and will drive each other, to move, and relieve the wind resistance upon the second bar (22). Thus, the second bar (22) will not distort easily and can be kept in good condition after a long time of use. Hence, the strength of the whole umbrella rib structure is greatly enhanced.

Moreover, the umbrella pole component (2) further comprises a third umbrella receptacle (14) sleeved on the umbrella pole (2). Between the third umbrella receptacle (14) and the second umbrella receptacle (13), a spring (6) is configured. The top end of the spring (6) pushes against the bottom of the second umbrella receptacle (13), and its bottom end pushes against the top of the third umbrella receptacle (14). And the umbrella rib components (2) further includes a fifth bar (7). One end of the fifth bar (7) is pivoted on the third umbrella receptacle (14), whale the other end is, pivoted on the third pivot connecting base (28).

More specifically, by sliding the third umbrella receptacle (14) up and down, it will drive the fifth bar (7), and the fifth bar (push the third bar (23), an the third bar (23) will unfold the fourth bar (24) through the movable pivot connecting base (29), and subsequently unfold the first and second bars (21, 22) to open the umbrella. Based on this, when folding or unfolding the inverse folding umbrella, the third umbrella receptacle (14) and the fifth bar (7) can provide an assistance, so that the inverse folding umbrella can be folded or unfolded smoothly.

In the above structure, the external surface of said third umbrella receptacle (14) has threads (141), and the third umbrella receptacle (14) is further provided with a threaded cap (8) that matches the threads (141). Based on this, the threaded cap (8) can fasten the edge of the inner fabric (10) of the inverse folding umbrella to further intensify the fixation of the inner fabric (10), so that the edge of the inner fabric (10) will not expose outside or have loose threads.

In the above structure, said tail bead (3) further includes: a first fixing piece (31) that is connected to one end of the second bar (22), and a second fixing piece (32) that is connected to the first fixing piece (31). One side of the first fixing piece (31) is further configured with an intersecting hole (311), and one side of the second fixing piece (32) is further configured with a through hole (321).

Specifically, by adopting the tail bead (3), the inner and outside umbrella fabrics (100, 200) of the inverse folding umbrella are respectively fixed on the second bar (22) to enhance the strength and wind resistance of the inverse folding umbrella.

Secondly, through combined application of the inner and outside umbrella fabrics (100, 200), the umbrella rib components (2) can be hidden between the inner and outside umbrella fabric (100, 200), so the inverse folding umbrella has better appearance while having higher strength. Such a design can greatly promote the consumers' willingness to buy and will meet the market demand.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrated embodiments and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
