Abstract
An energy storing device comprises a first drum, a second drum and at least one intermediate drum, an elastic cord wound from the first drum to the second drum via the intermediate drum, and means for mechanically connecting the drums so that the peripheral displacement of the second drum is greater than that of the intermediate drum and that of the intermediate drum is greater than that of the first drum. By providing the at least one intermediate drum, energy output from the device can be obtained even if the initial strain of the elastic cord is zero, and high energy output efficiency can be obtained in comparison with conventional one drum and two drum devices.
