Abstract
The invention relates to a safe umbrella frame, which includes a shaft, a runner, and an umbrella frame being composed of several frame units. Each frame unit includes one or more main ribs and at least one U-shaped branch rib, wherein the opening ends of the branch rib are folded inward to make the sharp rims of the branch facing inside. Hence, user will not be hurt as opening or closing the umbrella if he contacts with the bottom of the branch rib in accident. That obtains the safe purpose of the present invention.
Description
- As shown in
FIG. 1 , an umbrella usually has a shaft (1), a runner (4), and an umbrella frame (2), which is composed of several frame units. Each frame unit includes one or more main ribs (3) and at least one branch rib (5). The branch rib (5) has its two ends being pivoted with the main rib (3) and the runner (4). It is known that the branch rib (5) always has a U-shaped cross section, as shown inFIGS. 2 and 3 , in order that the umbrella can arrange the frame with a small volume when it is closed. Hence, the opening end of the branch rib (5) becomes a sharp rim (51) as it is manufactured by cutting. When a user operates the umbrella to open or close, his fingers would be hurt if touching the sharp rim (51) of the branch rib (5) in accident. - The present invention is to provide a safe umbrella frame to overcome the drawback of said known structure. The branch rib has its opening end be folded inward to prevent users from being hurt. Now, accompanying with the following drawings, the character of the present invention will be described here and after.
-
FIG. 1 is a perspective view showing a traditional umbrella frame and a user's hand. -
FIG. 2 is a perspective view showing the conventional branch rib ofFIG. 1 . -
FIG. 3 is a plan view ofFIG. 2 . -
FIG. 4 is a perspective view showing an umbrella frame and a user's hand according to the present invention. -
FIG. 5 is a perspective view showing an embodiment of the branch rib according to the present invention. -
FIG. 6 is a plan view ofFIG. 5 . -
FIG. 7 is a perspective view showing another embodiment of the branch rib according to the present invention. -
FIG. 8 is a plan view ofFIG. 9 . - Referring to
FIG. 4 to 6, the present invention mainly relates to an improvement of a branch rib (5) of an umbrella, which includes a shaft (1), a runner (4), and an umbrella frame (2) being composed of several frame units. Each frame unit includes one or more main ribs (3) and at least one branch rib (5). The character of the present invention is to fold the opening ends of the branch rib (5) inward. Hence, the sharp rim (51) of the branch rib (5) is faced upward and the bottom portion of the branch rib (5) becomes a smooth plane. It is to be understood that any user will not be hurt when he opens or close the umbrella even touching the branch rib (5) in accident. - Referring to
FIGS. 7 and 8 , the branch rib (5) is capable of being modified that the opening ends are folded inward to make the sharp rims (51) face centrally. This can also obtain a safe purpose for preventing hurting user's fingers. - Accordingly, the present invention has a most character that the sharp rims (51) of the branch rib (5) are folded to avoid contacting with user for a safe effect. It is then understood that the above-mentioned embodiments are only exemplary of the present invention. Other modifications, such as the opening ends of the branch rib are folded inward equal or more than ninety degrees, are still claimed in this application.
