Abstract
Abstract A clothespin made of plastic as one unit, having two opposite pin plates, an elastic bridge formed between intermediate portions of the pin plates, an elastic plate respectively extending from a bottom end of each pin plate and bending inward, one elastic plates having a bending stopper formed at the end and two projections extending up and under near the end stopper, the elastic plate with the stopper being pressed upward to let the top of the other elastic plate push and support the former elastic plate so as to keep both of them in that position and to be compressed by the lower portions of the pin plates to open the upper portions for pinching clothes between them.

Claim 1
Independent Claim
204 words
A clothespin made of plastic as one unit, comprising; two opposite pin plates having teeth on upper inner portions for pinching clothes, an elastic plate extending bendingly inward from a bottom end of each pin plate, a slightly bending stopper formed at the end of one of the elastic plates, a projection on and under the same elastic plates near the end stopper; an elastic curved-up bridge formed between intermediate portions of said two pin plates to supply elasticity to recover said pin plates its original closed position after lower portions of said pin plates are pressed inward to force open the upper toothed portions for pinching clothes; and said elastic plate with the stopper and the two projections being pressed upward or inward to let the top of the other elastic plate push and support the upper end of the lower projection of said elastic plate at its place so that said two elastic plates may also have elasticity to recover their position after pressed inward by the lower portions of the pin plates, in addition to that of said elastic bridge, so as to always keep the upper toothed portions of said pin plates tensely closed up for pinching clothes between them.
