Description

TITLE: AN IMPROVED UMBRELLA BACKGROUND OF THE INVENTION: The present invention relates to an improved urnbrella, and more particularly to an umbrella which can be operated easily and has a confirmed structure In prior art, there are umbrellas being designed for easy use. One kind i3 ?tn umbrella which can be operated to open or close handledly or automatically as chose. This kind of umbrelles has provided with yaps on the shaFt and locks inside the shaft.This design will cause many drawbacks, such as the rain and/or dust will enter the shaft which mar damage the iniier means, the convax of the U-shaped spring stands long to engage with the outer tube and will be destoried soon, and the elastic force of main spring may damage the gaps and/or the outer tube of the shaft whenever openiny or closing the umbrella.

SUMMARY OF THE INVENTION: It is the purpose of this present invention therefore, to mitigate and/or obviate the above-mentioned drawbacks iri the manner set forth in tie description of the preferred embodiment The primary purpose of the present invention is to provide an umbrella capable of being operated by handling or automating as chose.

A further purpose of the present invention is to provide an improved umbrella which has a confirmed structure and can be operated conveniently.

Another purpose of this invention is to provide a utilized umbrella which can prevent I;he undesired @ rain and/or dust from entering the shaft of the umbrella to avoid the dainagement.

Further purposes and advantages of the present invention will become apparent as the following description proceeds, and the features of novelty which characterity in the claims annexed to and forming a part of this invention.

BRIEF DESCRIPTION OF THE DRAWINGS: Figure 1 is an exploded perspective view ol an umbrella in accordance with the present invention.

Figure 2 is a oross-sectional view of the umbrella in its closed manner according to the present invention.

Figure 3 is a cross-sectional view oF the umbrella in its opened manner according to the present invention.

Figure 4 is a cross-sectional view oF the umbrella in the manner of operatiny by handling of this invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT: Now referring to the figures, it can be seen that tl-le present invention includes a cap (1) mount@d on an upper tube (5). A runner (A) and a runner ( B ) are provided arround the upper tube (5) as well as an outer tube (2), wherein the convaxes formed at the inner hole of the runner (A) are capable of engaging with the curved channels (51) on the upper tube (5). Two gaps (21) are Wormed on the top end of the outer tube (2) and the relative sliding guides (22) are also provided on the outer tube (2).A buffer (23) with a spring (25) is provided between the tube (2) and the stopper (52) provided under the upper tube (5), and has a concave (24) being relative to the sliding guide (22) of the tube (2).

An inner tube (3) has fixing holes (31), and gaps (32), (33), (34), and (35). There are fixiny hole (26) and gaps (27), (28), and (29) formed on the outer tube (2j.

U-shaped spring (36) is provided inside the inner tube (3) and has its two circular convaxes (37) engaged with the fixing hole (31) of the inner tube (3). A hook (4) has a U-notch (41) for engaging with a flange (43) of a bar (42).

A steel spring (44) is provided hav i nj- its two ends ( 45 ) connected with tie holes (46) ,( 47) of the hook (4) and bar (42), for Forming a single means to be assembled or used conveniently.

A lower ring (6) is provided arround the inner tube (3) and has a forky lower end (61) receiving a spring (62) and received irl a handle seat (7); wherein including two button (A'), (B') beside the seat (7) and a handle on the lower end of the seat (7).

As shown in figure 2, it is in z manner to be open automatically. At this time, the upper tube (5) is pressed downward to press the main spring (8). When pushing the button (B'), the flange (43) of the bar (42) will push the hoole (B1) of the runner (B) out of the gap (33), which forces the runner (A) moving downward as well as the runner (B) moving upward to open the umbrella as shown in figure 3.

In closing the umbrella, one can push the button (A') to force the hook (4) leaving the gap (34). Due to the inner elastic force of the frames (9), the cover, and the spring ( 91 ) as well as the extension force of the spring (62) inside the lower ring (6), the outer tube (2) can be moved upward very quickly and the umbrella is automaticcally closed as shown in figures 2 or 4.

Please referring to figure 4, it i3 in a manner of the present invention to be operated by handling. it can be seen that the outer tube (2) has been moved upward and the fixing holes (26) are engaged with the circular convaxes (37) of the U-shaped spring (36). At the same time, the sliding guides (22) have pressed the buffer spring (25) as in a static manner which can obviously prevent the fixing hole (26) and the U-shaped spring (36) from damagement. And it is to be understood that the assembly can prevent the undesired rain and/or dust from entering the shaft.

While th invention has been explained in relation to this preferred embodiments, it is to be understood that vat-ious modifications thereof will become apparent to those skilled in the art upon reading this specification. Thus, it will be most appreciated that the invention disclosed herein is intended to cover all such modifications as fall within the scope of the appended claims.
