Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an umbrella structure, and more particularly to a flexible omni-umbrella having the advantages of comprehensive shielding, hard to be damaged and easy to be furled.

2. Description of the Prior Art

With reference to FIG. 1, there is shown a stereo view of a conventional umbrella. As shown in FIG. 1, the conventional umbrella includes: a handle grip 1′, a first base 2′, a second base 3′, a plurality of first umbrella ribs 4′, a plurality of second umbrella ribs 5′, a plurality of beads 6′, an umbrella fabric 7′, and a plurality of clamping members 8′. There are having two procedures for spreading the conventional umbrella: First, in procedure (1), the second base 3′ is pushed to move toward the top end of the handle grip 1′; Next, in procedure (2), the second umbrella ribs 5′ are spread by the push of the second base 3′, therefore the first umbrella ribs 4′ are simultaneously spread due to the interlink of the second umbrella ribs 5′, and then the umbrella is completely spread. On the contrary, the flexible omni-umbrella can be furled by reversely operating the above-mentioned procedures (1) and (2).

The above-mentioned conventional umbrella includes the drawbacks and shortcomings as follows:

1. Because the main umbrella framework of the conventional umbrella is constructed by the first umbrella ribs 4′ and the second umbrella ribs 5′, there are many joint structures used for connecting the first umbrella ribs 4′ and the second umbrella ribs 5′; and usually, the structure strength of such umbrella framework is weak. Thus, when the conventional umbrella is hit by a strong wind in a fully spread condition, the main umbrella framework of the umbrella may be damaged or form some sharp structures, and the user could be hurt by the damaged umbrella or those formed sharp structures.
2. The conventional umbrella can merely used for shielding one directional plane, so that, if the rain brought by wind strikes the user multi-directionally, the conventional umbrella cannot protect the user from being wetted by rain.
3. Although the conventional umbrella can be furled to a long strip formation, the long strip umbrella is space-occupied and hard to be carried.

In view of the conventional have many drawbacks; the umbrella designers propose a flexible omni-umbrella. Please refer to FIGS. 2A and 2B, there are shown stereo views of the flexible omni-umbrella, in which the flexible omni-umbrella is disclosed by an R.O.C. patent with application number of 101207729, and includes: a rod 1a, a flexible wire 2a and an umbrella fabric 3a. The rod 1a has a through hole portion 11a and a fixing portion 12a provided on the two end thereof. The flexible wire 2a is fixed on the fixing portion 12a by one point thereof. In addition, two terminal ends of the flexible wire 2a are slidably passed through the through hole portion 11a of the rod 1a oppositely, and are further connected to each other by a bridge member 21a after being bent, so as to form a stereoscopic framework. Therefore, as shown in FIG. 2A, the stereoscopic framework consisting of one water-drop-shaped coil and an ellipse-shaped coil is constructed, wherein the water-drop-shaped coil and the ellipse-shaped coil are fixed by disposing two joining members (A′, B′) on two cross points thereof. Eventually, as shown in FIG. 3B, the umbrella fabric 3a is covered the stereoscopic framework.

Although the flexible omni-umbrella of FIGS. 2A and 2B proposed by the R.O.C. patent of 101207729 is able to solve the some shortcomings occurred in the conventional umbrella liking FIG. 1 shows, the flexible omni-umbrella still has the following drawbacks:

(1) Although the umbrella fabric 3a covering the stereoscopic framework formed by the flexible wire 2a is capable of shielding rain comprehensively, there are some crevices produced on the surface of the umbrella fabric 3a when the flexible omni-umbrella are fully spread, and the crevices allows the external rain getting into the inside of the umbrella, so as to wet the user.
(2) Since the rod 1a cannot be rotated, the user must directly compress the stretchy segments 111a of the rod 1a in order to furl the umbrella.

Accordingly, in view of the conventional umbrella and the flexible omni-umbrella disclosed by the R.O.C. patent with application number of 101207729 still have shortcomings and drawbacks, the inventor of the present application has made great efforts to make inventive research thereon and eventually provided a flexible omni-umbrella.
