Abstract
Description
[Technical Field]
[0001] The cause of stiff shoulders is daytime activities motion When you are doing exercise, your body temperature rises, your blood vessels become thicker, and blood flow improves. However, when you go to sleep at night, depending on how you cover yourself with your futon, drafts can get in through the shoulders, making your shoulders cold. The blood vessels in your shoulders, which are warmed by good blood flow during the day, shrink, causing poor blood flow, and it is thought that this is when substances that cause pain and lead to stiff shoulders accumulate. As a measure to alleviate stiff shoulders, technology has been developed to create a pocket with a raised area that can be used to insert magnets or heating pads into the collar of a futon or blanket, which can be placed at the shoulders while sleeping to improve blood flow and prevent catching a cold. [Background technology]
[0002] None in particular [Prior art documents]
[0003] Patent application No. 2022-76324 Summary of the Invention [Problem to be solved by the invention]
[0004] To create a quilt or blanket that prevents drafts from entering the shoulder area of a person sleeping and cooling the shoulder area of the quilt or blanket. the law of nature , while sleeping You can warm your shoulders I thought that persistent stiff shoulders and shoulder pain would heal naturally, so I wondered what to do and a problem arose.
[0005] To prevent drafts from entering through the shoulders when sleeping on one's back or side, a recess or protrusion is attached to the nape of the shoulders of a futon or blanket, and a heating pad is placed there. and magnets The pocket can be used to store items such as:
[0006] When you sleep using the futon or blanket of the present invention, drafts will not get in through the shoulders or nape of the futon, and the heat will be and magnets By being warmed by the device, the severe stiffness in my shoulders and neuralgia in my arms were alleviated and healed naturally. [Brief explanation of the drawings]
[0007] [Figure 1] This diagram shows how the bottoms of ordinary blankets and comforters have been made a little longer, with convex and concave parts attached to the nape of the neck, and pockets for inserting heating pads or magnets. Mode for carrying out the invention
[0008] The bottoms of ordinary blankets and comforters are made a little longer, and a protrusion or recess is attached to the nape of the neck, and a heating pad is placed there. and magnets It has a pocket for storing things, and when the convex or concave parts become a problem, this futon or blanket can be used upside down. [Example]
[0009] A few days before the judo or baseball match that was scheduled to start tomorrow, I followed the coach's instructions and used the invented futon or blanket to sleep so that my shoulders wouldn't get cold, and my shoulders felt much better.
[0010] When sleeping at night, the shoulders get cold due to drafts, and only the shoulders that are warmed by improved blood flow during the day get cold. This causes blood vessels to constrict, leading to poor blood flow and stiff shoulders. It is thought that this is caused by the accumulation of pain-causing substances, and as in the present invention, by creating convex or concave parts on the nape of the comforter or blanket. By creating a pocket in which you can put a heating pad or a magnet, To prevent drafts from entering through the shoulders while sleeping This can improve blood flow in the shoulder area. When the futon and bedding manufacturing industry learned what was possible, the potential for industrial use became extremely high. [Explanation of symbols]

Claims
[Claim 1] To provide an invention in which the nape of a person's neck is provided with an uneven portion and a pocket for inserting a magnet or a heating pad so that drafts do not enter through the neck of a blanket or a comforter used to cover the person while he or she is sleeping, cooling the shoulders and causing coldness that leads to stiff shoulders.
