AI Technical Summary
Conventional umbrellas with sharp rod-shaped tips pose a risk of eye injury when carried sideways, especially for children and adults behind the umbrella holder.
A circular cap-shaped object with a diameter of about 3cm and a gentle curve is attached to the tip of the umbrella, opposite the handle, to prevent direct contact with the eyes.
The circular shape distributes pressure and reduces the risk of eye injury when the umbrella is closed or carried sideways, aligning with the average human eye dimensions.

Abstract
Description
[Technical field]
[0001] The present invention relates to an umbrella that has a slightly rounded, circular cap-like object attached to the tip of the fabric or ferrule on the side opposite the handle. [Background technology]
[0002] Traditionally, the tip of the umbrella has overwhelmingly been pointed and rod-shaped (thin cylinder, cone, or truncated cone). [Prior art documents] Registered literature
[0003] Practical registration document 1: Jitsuto 3228604 Practical registration document 2: Jitsuzenhei 03-098618 Summary of the Invention [Problem to be solved by the invention]
[0004] Traditionally, umbrellas have a sharp tip on the side opposite the handle. Umbrellas are often held sideways when not in use, and the sharp tip has been a problem in that it can injure people behind. On stairs, the tip can come into contact with the face of people behind, and even when not on stairs, when an adult holds an umbrella, it is at eye level with children behind them, and there have been many cases of injuries. Ophthalmologists have sounded the alarm, and warnings about the risk are broadcast on television almost every year during the rainy season. The present invention has been made to eliminate the above-mentioned risk of umbrellas injuring people's eyes in particular. There are various theories as to why umbrellas have bases, but one is that it prevents the fabric from touching the ground directly. Another is (from GONWEB Takumi no Kasamiya Take Case Studies) that the roots of modern Western umbrellas lie in England, where women's parasols were originally more popular than rain umbrellas, and rain umbrellas were born from these, but as men were resistant to them, they were made to resemble the walking sticks that men carried at the time, and so they became popular. The roots of the length of an umbrella lie in walking sticks. The reason this shape has not been improved is probably because Western umbrellas are a culture that was introduced from overseas, and it was considered common sense specific to the industry. Also, Western umbrellas are made to similar standards all over the world, so it may not have been questioned. (End of quote) It is said that an adult male's umbrella needs to be 55cm long to keep them dry. If you add the ferrule and handle to that, it is too long to hold in your hand or hang the handle on your wrist when carrying it, even when it is not raining, so you often end up holding the umbrella sideways. As for whether a ferrule is necessary to hold the umbrella fabric together, it is thought that a long ferrule is not necessary, since folding umbrellas do not have long ferrules. Also, when elementary school students walk to and from school, even when it is not raining, they generally hold their umbrellas horizontally. [Means for solving the problem]
[0005] Attach a circular object about 3 cm in diameter to the tip of the umbrella opposite the handle, with a gentle curve that follows the curve of the top of the umbrella when it is open. When a new umbrella is manufactured, a circular object of that shape is provided at the top of the fabric from the beginning, and if an umbrella with a ferrule is to be manufactured, a cap-like object is provided at the tip of the ferrule, and a cap-like object that can be attached to the ferrule of an existing umbrella can be provided. Effect of the Invention
[0006] The average size of a human eye is said to be 2.7 to 3 cm wide and 1 cm tall. Therefore, if the umbrella is circular and has a diameter of 3 cm or more, the entire umbrella will not directly enter the eye and cause injury, and even if the umbrella hits the eye when it is closed and held sideways and swung, the pressure is dispersed and the damage to the eye is reduced. If the circle has a gentle curve that follows the roundness of the top of the umbrella when it is open, it is impossible for the circumference of the circle to enter the eye due to the angle. The risk of stabbing the eyes has been pointed out in the past, and some have been registered for practical use, but I have never seen one. This invention may seem simple at first glance, but it is a unique shape for protecting the eyes, and it is precisely because it is simple that it is likely to become widespread. The danger will not go away unless everyone starts carrying one, to the point where it is recognized as the "standard shape of an umbrella." [Brief description of the drawings]

[Figure 4] Umbrella when using this invention [Diagram 5] Umbrella when using this invention when attached to a ferrule DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] Hereinafter, an embodiment of the present invention will be described. At the tip of the umbrella (1) opposite the handle, there is provided a circular object (2) made of plastic, metal, rubber, silicon, etc., with a gentle curve that follows the roundness of the top of the umbrella fabric when it is open, and a diameter of about 3 cm or more. The present invention is the structure described above. If a traditional stick-like ferrule is needed, a cap can be attached to the tip of the ferrule, and if an existing umbrella is used, a cap can be attached to the end of the ferrule. When the umbrella is in use, the rain drops onto the umbrella fabric, just like a conventional umbrella, because the umbrella has a gentle curve. When a wet umbrella is folded, the amount of water that falls off the umbrella varies depending on whether it is a top-integrated type, a tip-attached type, or a cap type, but there are various types that can be considered, such as a type that fills the inside of the curved part or a strainer type that lets water escape.
