寝椅子の開発 1/4
/Development of chaise longue 1/4
「朝目覚めると腰が痛い。」そんな悩みを長年抱えてきました。そろそろ何とかしなくては・・・・今回は私自身が発注者です。わがままな発注者の依頼を受けて、全くのオリジナルの寝椅子をゼロから開発しました。
When I wake up in the morning, my back hurts. I have had such troubles for many years.I have to do something about it … This time I am the orderer.At the request of such a selfish orderer, I have developed a completely original chaise longue from scratch.

実はこのブログ、特に独創的な事例には海外からとても勇気づけられるコメントをいただいています。
そんな方々に向けて、少しでも読みやすくしたいので、今回は対訳付きの事例紹介に挑戦してみます。なお、日本の方で英語の得意な方、この拙い英文を添削していただけるようお願いします。
Actually, this blog, especially the original introduction, has received very encouraging comments from overseas.
For such people, I want to make it as easy to read as possible, so this time I will try to introduce a case study with translation.
If you are Japanese and are good at English, please correct this poor English sentence.

After many years of trial and error, the conclusion was that sleeping on a flat surface is no good.

High-class bets and electric bets controlled by the latest smartphones. All non-flat beds are expensive and hard to come by. Development started with the idea that “then you have to make it myself”.

It’s a good idea to sleep on the sofa that was close to me, put stools side by side to support my legs, put a cloth in the anchor, sleep for months and improve, and finally this shape became. The seasons changed during trial and error, and the days of buying a sleeping bag for the winter, actually sleeping every night, and verifying the next morning are finally over.

Make a pattern that copies the shape.The best shape for my body, which I had a hard time collecting, became a paper pattern.

Draw a sketch with reference to this shape. The sketch was completed, considering the detailed structure and the convenience of the materials.

The material is a 910 x 1820 x 15 mm lumbar core. Place the actual size paper pattern and decide the shape according to the actual size.

I will make a full-scale pattern for each part, this is the seating surface. Only half of the symmetrical parts are made with the center line as the boundary.Actually, this shape is conscious of the”Dreadnought” of my favorite Martin guitar.

Copy the line to the material.

At the same time, draw the arrangement of the groove for curving.

Copy other parts in the same way.

Cut out the parts with a jigsaw.

Cut a groove with a circular saw.

Leave a groove of about 1 mm to the surface and dig it so that it will not be separated. The way the circular saw blade comes out is adjusted.

Since the backrest part is curved in an S shape, the groove will be dug from both the front and back like this.

Cut out the surface on which the legs will be placed in the same way.

Arrange the edges

Dig a ditch.

Since this is bent toward C, dig only from one side.

Since the part on which the legs are placed is movable, pin the actual size type and try moving it to determine the shape of the details so as to avoid interference with other parts.

Also stores the legs. feel well.
