Frame made of reinforced plastic withstands wind speed of 15m / s, and is tough, hard to break and tough structure resisting strong wind. It is a folding umbrella with a structure that can be easily returned to its original state even if the umbrella is overturned by strong winds.
If you want to design a strong umbrella bone, you must select a hard and thick material, which inevitably increases the product weight. Amvel Inc. aims to create a structure that withstands strong winds without increasing the weight of the product, and develops products based on the idea of "making the wind". In other words, by making the umbrella bone flexible in response to the wind, a structure that is not easily broken is realized.
Normally, folding umbrellas use metal such as aluminum to reduce the product weight. However, aluminum used for umbrellas has weak strength, and if exposed to strong winds, it will be damaged if it bends or breaks bones. In order to "make the wind", it is required to be as flexible as bamboo, and by reviewing the conventional aluminum material and adopting reinforced plastic as the umbrella frame material, a flexible frame against strong wind was created.
Umbrellas can be damaged by strong winds and may break. "Toughness mini" is a structure that is easy to return the frame by using a reinforced plastic material. In addition, it has excellent durability, and it has been repeatedly inspected 100 times after turning it back, but there is no damage or deformation.
It is not only reinforced plastic materials that are strong. It is a device that is hard to break everywhere.
The folding umbrella is usually structured to fold in three steps, but the folding connection is made of metal rivets. Metal rivets are not easily broken, but they can bend or break under load. Rivets can be heavily loaded by sudden winds such as gusts. "Toughness Mini" eliminates the rivets that cause failure, and the joint part is a built-in integral type of reinforced plastic frame.
The "Toughness Mini" shaft has a dodecagon shape (12-sided) and is hard to break.
* Conducted a bending strength test of the shaft which is not usually a folding umbrella. A 1.5 kg weight test was carried out for 1 minute, but the shaft did not break.
The part that slides when opening and closing the umbrella is called the runner, but the "Toughness Mini" runner does not require button operation. Just slide the runner when opening and closing the umbrella.
The shaft of a common folding umbrella is thicker at the handle and thinner at the top. "Toughness Mini" is the opposite structure, with a thicker top. When the upper part is thick, the runner and the shaft fit, and it becomes a structure that is hard to be attached to a strong wind.
The common folding umbrella rib is six, but "Toughness Mini" has eight ribs. It may feel like a little difference, but it will make the umbrella frame hard to stick because it will support the fabric firmly if there are a large number of ribs.
The "Toughness Mini" fabric is coated with "Easy-Dry", which has a strong water-repellent finish. By modifying the water repellent into fine particles of nano class, the water repellent coating penetrates deep into the fiber and becomes difficult to peel off.
Umbrella is a product that is difficult to disassemble and recycle because the structure is complex and various materials are used. Broken umbrellas can be dumped in public places, incinerated, or disposed of in landfills. Disposal is, of course, a very annoying act, and incineration generates carbon dioxide. There is also a limit to landfilling, and you should still reduce umbrella waste. We think that we can contribute to the environment by using a durable umbrella rather than an umbrella that is quickly broken and turned into garbage.
