Chain connector

Abstract

A link for connecting a chain. The link has a first outer chain plate, a first pin, a second pin, and a second outer chain plate. The first outer chain plate has two circular holes. The pin has, at a first end, an enlarged flat head and, at a second end, a dome head near which a groove extends so as to form a neck. The second outer chain plate has a circular hole and a hole consisting of a relatively small semicircular hole overlapping partially with a relatively large semicircular hole. In a plant, the first pin is (a) inserted through a hole of the first outer chain plate, holes of two inner chain plates, and the circular hole of the second outer chain plate and (b) riveted at both heads to thereby combine these elements conventionally. The second pin is inserted through the other hole of the first outer chain plate and the enlarged flat head thereof is secured to the first outer chain plate. A bike rider can (a) insert the dome head of the second pin through holes of other two inner chain plates, (b) move the dome heads toward each other, whereby the dome head of the second pin is permitted to be inserted through the relatively large semi-circular hole, and (c) release the second pin to thereby permit the neck to be received in the relatively small semicircular hole.
