Abstract
A dumbbell is made up of a carrying seat, a plurality of weights, and a weight-selecting device. The carrying seat is formed of two plates, two hollow rods and a grip. The plates are provided with a plurality of through holes and carrying grooves. One of the two plates is provided with a receiving cell. The weights are formed of two identical block bodies each having two through holes and a plurality of carrying grooves. The two block bodies are provided with two connection rods fastened therebetween to facilitate the juxtaposing of the weights on the carrying seat. The weight-selecting device is disposed in the receiving cell and is composed of an adjustor, and two pins which are disposed in the hollow rods such that the pins are connected at one end thereof with the adjustor, and that the pins are corresponding at other end thereof to one of the through holes of the plates, and further that the two pins can be extracted from or retracted into the hollow rods. The carrying seat can be thus coupled with a desired number of weights.
