Diabolo is the name given to the shape of the lampshade. The diabolo lampshades were very popular in the 1950s. You can find several examples on Vintageinfo.
The diabolo, some yo-yo, has its origin in China. It’s a double-coned bobbin that can be twirled, tossed, and caught on a string secured by two sticks, one held in each hand. The first diabolo’s were made of bamboo and they made some whistling sound.
In the eighteenth century, the diabolo became known in England and France. The term “diabolo” was made up by French engineer Gustave Phillippart, who developed the modern diabolo in the early twentieth century and he was re-released. Since then, he has been widespread.
