paperclip

详情

A paper clip is usually a thin wire in a looped shape that takes advantage of the elasticity and strength of the materials of its construction (usually steel or some other metal, but sometimes plastic) to compress and therefore hold together two or more pieces of paper by means of torsion and friction. Some other kinds of paper clip use a two-piece clamping system.

Recent innovations include multi-colored plastic-coated paper clips and spring-fastened binder clips.

 

According to the Early Office Museum, the first patent for a bent wire paper clip was awarded in the United States to Samuel B. Fay, in ***7. This clip was originally intended primarily for attaching tickets to fabric, although the patent recognized that it could be used to attach papers together.[1] Fay received U.S. patent *4,**8 on April *3, ***7. Although functional and practical, Fay's design along with the *0 other designs patented prior to ***9 are not considered reminiscent of the modern paperclip design known today.[2] Another notable paper clip design was also patented in the United States by Erlman J. Wright in ***7. This clip was advertised at that time for use in fastening newspapers.[1]
