Abstract

The invention relates to a reinforced rib of a three-folded umbrella, which is provided with a reinforced rod in the second rib of the frame. The second rib is then to obtain a perfect strength for resisting strong wind and can be effectively used since damage is prevented. The umbrella will be obviously more utilized for use.

Description

    FIELD OF THE INVENTION
  • The present invention relates to a reinforced rib of a collapsible umbrella, which is particularly about an improvement of a three-folded umbrella.
    • BACKGROUND OF THE INVENTION
  • Generally, a three-folded umbrella is an umbrella having three ribs to assemble the frame. As in use, the second rib of the frame usually bears the most pressure of wind. It is known that the second rib is always the first broken point when strong wind blows. In order to overcome this prior drawback, the conventional method is to provide the second rib with a different material, such as steel, FRP, or carbon fiber. The strength of such second rib can be increased but the cost in manufacturing and assembling will be high. Moreover, this rib must be made by another independent procedure and it always increases the volume of the collapsible umbrella in closed state.
    • SUMMARY OF THE INVENTION
  • The present invention is to provide a reinforced rib of a three-folded umbrella, wherein a reinforced rod is provided directly in the U-shape space of the second rib. Hence, the three-folded umbrella with the reinforced rod can provide a perfect strength to resist wind and to prevent from damage. Now, accompanying with the following drawings, the character of the present invention will be described here and after.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1-1 is a perspective view showing a single frame of a three-folded umbrella according to the present invention.
  • FIG. 1-2 is an exploded perspective view showing the second rib and the reinforced rod of FIG. 1-1.
  • FIG. 1-3 is an assembled perspective view of FIG. 1-2.
  • FIG. 1-4 is a plan view showing the three-folded umbrella in opened state according to the present invention.
  • FIG. 1-5 is a cross-sectional view alone line A-A of FIG. 1-4.
  • FIG. 2-1 to 2-5 are views showing another embodiment with relating state to FIG. 1-1 to 1-5 according to the present invention.
  • FIG. 3-1 to 3-5 are views showing a further embodiment with relating state to FIG. 1-1 to 1-5 according to the present invention.
  • FIG. 4-1 to 4-5 are views showing still another embodiment with relating state to FIG. 1-1 to 1-5 according to the present invention.
  • FIG. 5-1 to 5-5 are views showing a modified embodiment with relating state to FIG. 1-1 to 1-5 according to the present invention.
  • FIG. 6-1 to 6-5 are views showing a further modified embodiment with relating state to FIG. 1-1 to 1-5 according to the present invention.
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • The present invention is to provide an improvement about a three-folded umbrella. In first embodiment in FIG. 1-1 to 1-5, it shows a normal three-folded umbrella, which includes three ribs to assemble a frame. The characteristic of the present invention is to provide a reinforced rod (2), which is received directly in the U-shape space of the second rib (1) of the umbrella and can be fixed therein by the lock (11) formed on the rib (1). The reinforced rod can be made of FRP, carbon fiber, metal, etc. Hence, the second rib (1) with the reinforced rod (2) inside can obtain a better strength for preventing from damage.
  • It can be found that it is unnecessary to change the structure of the original umbrella. The present invention just provides the reinforced rod (2) in a conventional second rib (1) and connects them together. It increases the strength of the second rib to resist strong wind that obtains the improvement and utilization.
  • The above embodiment relates to an application of a manual umbrella and it is only an exemplary. Other embodiment with the same spirit of the present invention will be also claimed in this invention. Such as shown in FIG. 2-1 to 2-5, it is an application of an automatic umbrella being similar to FIG. 1-1 to 1-5.
  • FIG. 3-1 to 3-5 show another manual three-folded umbrella with different structure of frame, which includes an elastic rib (4) extended through the second rib (1). The present invention provides a reinforced U-shape rod (3), which is received in the second rib (1). The U-shape space of the reinforced rod (3) provides the elastic rib (4) passing through. FIG. 4-1 to 4-5 show an automatic collapsible umbrella being similar to FIG. 3-1 to 3-5.
  • FIG. 5-1 to 5-5 and FIG. 6-1 to 6-5 are also modified embodiments, which have the second rib (1) provided with the reinforced rod (3) for increasing the strength of the frame.
  • Accordingly, the improvement of the present invention is to provide a reinforced rod in the second rib of a three-folded umbrella. Hence, the strength of the second rib is increased that prevents from damage and obtains utilization. Furthermore, since the reinforced rod is received directly in the second rib, the volume of the collapsible umbrella will not be increased.
  • In above embodiments, the reinforced rod is formed a round shape or a U shape. Actually, other modified shape can be permitted in the present invention, such as being semi-circular, D-shaped, triangle, W-shaped, V-shaped, or M-shaped, all of which are recited in the scope of this invention.

Claims (4)
