Description

[Detailed Description of the Invention] This invention relates to a folding type Western umbrella that has an improved external shape in an open state and an improved folding device for the umbrella cloth.

As shown in FIG. 1, the conventional folding type Western umbrella 1° has a main rib 7 near the base end 8 and a lower opening black 2 rotatably supported by a support rib 4.
Further, the vicinity of the center of the support bone 4 and the upper potter's wheel 3 are rotatably supported by the backbone 5, and the vicinity of the pivot point of the support bone 4 of the support bone 5 is connected to the proximal end 8 of the main rib 7. The umbrella cloth 10 is rotatably supported by a bone 6°, and an umbrella cloth 10 is stretched over the upper surface between the tip 9 of the main rib 7 and the upper end of the upper potter's wheel 3.

Furthermore, when the umbrella 1° is folded, the umbrella cloth portion 11o between the base end 8 of the main rib 7 and the upper end of the upper potter's wheel 3 is automatically folded inward along the fold line. The central part 12 and appropriate parts of the middle ribs 5 and struts 4 are connected to string-like members 13.
It is provided in the folding device connected at 13'.

In the case of this Western umbrella of 1°, as is clear from Fig. 1, the umbrella cloth portion 11. Since it is not directly supported by the umbrella ribs, if the umbrella cloth portion 11° becomes flat or if the tension of the umbrella cloth 10 is strong, it will become concave downward.
There is a drawback that the appearance is significantly inferior to the plump appearance of a Western umbrella in the open state of a conventional Western umbrella in which the entire length of the umbrella cloth is stretched over the entire length of the main rib.

Further, since the umbrella cloth portion 11o is not supported by the umbrella rib in the open state, the umbrella cloth portion 11. There may also be inconveniences such as rainwater accumulating in the umbrella and making the umbrella heavy.

In addition, since the folding device is installed by passing one of the string-like members 13 and 13' through a hole provided in the backbone 5 or strut 4, the work is troublesome and requires a large number of man-hours, resulting in considerable processing fees. This is also one of the reasons for the rise in the cost of a 1° Western umbrella.

The present invention has been developed to compensate for the above-mentioned drawbacks; it has an excellent appearance when the umbrella is open, has good water resistance against rainwater during use, and can be provided at a low cost because the folding device can be installed extremely easily. The aim is to provide folding Western umbrellas.

2 and 3 showing an embodiment of the present invention will be described below.

In the folding type Western umbrella 1 according to the present invention, the proximal end 8' of the main rib 7 and the lower opening black 2 are rotatably supported by the supporter 4, and the supporter 4
The vicinity of the center and the upper potter's wheel 3 are rotatably supported by the central rib 5, and the vicinity of the pivot point of the central rib 5 with the support bone 4 and the main rib 7 are connected from the pivot point with the main rib 7 to the main rib. The umbrella cloth 10 is stretched on the upper surface between the tip 9 of the main rib 7 and the upper end of the upper potter's wheel 3, and is rotatably supported by a connecting bone 6 which is bent 14 after being extended to a required length on the extension line of the main rib 7. It was established.

Furthermore, the umbrella cloth 10 is in contact with 14 bends of the connecting bones 6.
The parts are loosely connected by flexible cord-like members 15 such as strong threads.

In the folding type Western umbrella 1 according to the present invention, since the back rib 6 extends for a required length on the extension line of the main rib 7, the umbrella cloth portion 11 between the base end 8 of the main rib 7 and the upper potter's wheel 3 in the open state is Because the length is shortened and forms an arc rather than a flat plate, the appearance when opened is almost the same as that of a conventional Western umbrella, in which the entire length of the umbrella cloth is supported by the ribs, and it has an excellent appearance. Since the umbrella cloth portion 11 has an arcuate shape, rainwater can be easily drained and the umbrella 1 does not become heavy due to rainwater.

In addition, the folding device does not require passing the string-like member 15 through the hole in the backbone 6, and only loosely connects the 14 bends of the backbone 6 to the umbrella cloth 10, so it is extremely easy to install and reduces processing costs. It can be prevented.

In this invention, the vicinity of the proximal end of the main bone and the lower mouth black are used as a support bone, the vicinity of the center of the support bone and the upper potter's wheel are used as the middle bone, and the vicinity of the pivot point of the main bone with the said support bone and the base end of the main bone. In a folding Western umbrella, the connecting bones are rotatably supported by connecting bones, and an umbrella cloth is stretched between the tip of the main rib and the upper end of the upper potter's wheel. A cord-shaped member is extended from the pivot point to the extension line of the main rib for a required length, and then bent and rotatably pivoted to the main rib. Since this is a folding Western umbrella characterized by loosely connected members, it has the following effects.

(1) It has an excellent appearance in the open state, making it fashionable, stimulating the purchaser's desire to purchase, and contributing to increased sales.

(2) Since it has good drainage against rainwater, it does not become heavy during use, making it extremely useful.

(3) Since the folding device is extremely easy to install, the processing fee is low, contributing to a reduction in cost.
