Description

[Detailed description of the invention] Industrial applications The present invention relates to an umbrella.

Conventional technology Conventional umbrellas consist of a handle, a frame, and a waterproof sheet, and the length of the handle is reduced to 1 for convenience when carrying.
Foldable umbrellas with a length of 1/2 or 1/3 are common, but they are expensive due to their structure.

Problems to be Solved by the Invention However, umbrellas having the handle and frame as described above are structurally expensive. The present invention aims to provide a disposable, inexpensive umbrella that solves the above-mentioned problems.

Means for Solving the Problems In order to solve the above problems, the present invention has a point on substantially the center line of the opposing sides as the center, and the center line is set as a ridge line, which is provided on one side from the center. A folding line, a plurality of folding lines provided radially on each side of the folding line to become either an upper or lower ridgeline, and a waterproof plate whose folded part becomes a grip when the folding line is bent. Its body forms an umbrella.

As described above, the present invention provides an inexpensive umbrella by providing fold lines radially on a waterproof plate body, bending the fold lines to form a grip portion, and curving the waterproof plate body. This makes it possible to provide this service.

Embodiment The umbrella of the present invention will be explained with reference to an embodiment shown in FIGS. 1 and 2. FIG. 1 is a perspective view showing the state of use, and FIG. 2 is a developed view. According to FIGS. 1 and 2, 1 is an oblong plate made of sheet-like waterproof paper or sheet-like waterproof plastic, and 2 is located approximately on the center line of the opposite sides of this plate 1. A bending line centered at point 3 of
4a, 4b, 5a, and 5b are folding lines that are provided two radially on each side of this ridgeline 2 and become either the upper or lower ridgeline, and 6a to 6f are folding lines when the folding lines are bent.
The small holes are formed at an angle so that the holes are formed in the portions that overlap to form the grip portion 7.

The umbrella of the present invention is constructed as described above, but to explain how this umbrella is used, the fold line 2 is bent to become the lower ridge line, and the fold lines 4a and 5a are folded to become the upper ridge line. When 4b and 5b are further bent to form the lower ridgeline, the oblong plate 1 is curved to form an umbrella. At this time, the bent portion forms a grip portion 7 having a hole 6 in which the holes 6a to 6f overlap. Note that the state of the umbrella is maintained by holding this gripping portion 7 by hand, but it is also possible to maintain the state of the umbrella by locking this gripping portion 7 with a Stella pull or the like. Further, the fold line may be formed as a crease or as a perforation. Furthermore, the above-mentioned waterproof plate body can also be manufactured by continuously processing a hoop-shaped body.

Effects of the Invention As described above, the present invention centers on a point substantially on the center line of opposite sides of a waterproof sheet made of an oblong plate, and extends from the center to one side, using the center line as a ridgeline. The same plurality of folding lines are provided radially on both sides of the umbrella, and the folding lines are bent to form a grip part to form an umbrella, thereby providing an inexpensive umbrella suitable for various outdoor events.

Claims (2)

[Claims] (1) A fold line centered on a point approximately on the center line of the opposing sides and provided on one side from the center, with the center line as the ridge line, and a plurality of fold lines radially on each side of the fold line. An umbrella formed of a waterproof plate with a folding line serving as either an upper or lower ridgeline, and a waterproof plate whose folded portion becomes a grip when the folding line is bent. (2) The umbrella according to claim 1, comprising a waterproof plate having a small hole so that a hole is formed in the grip when the folding line is bent.
