Abstract
A combination padlock with an improved rocker assembly as looking control device. The combination padlock contains a slide plate, a rocker assembly, a shackle, a predetermined number of numbered wheels, and a plurality of wheel sleeves respectively matching the numbered wheels. The slide plate is provided with a predetermined number of semicircular holes, each of the semicircular holes is adapted for receiving a spring and one of the wheel sleeves. An oblong hole is located between two of the semicircular holes, each of the semicircular holes is further provided with an angled flange corresponding in angle and dimension to a notch provided in each of the wheel sleeves. When a correct combination is dialed, the notches match the angles and the lock is unlocked. The rocker assembly contains a rocking hole, a retaining bar, and a rocking shaft. The rocking hole is dimensioned as to fit over a protuberance on the lower housing of the padlock such that the rocker assembly can be caused to pivot about the protuberance. The retaining bar is capable of being caused, by a downward movement of the slide plate, to move to retain a retaining head of the shackle when the angled flange of any one of the semicircular holes of the slide plate is not coincident with a coinciding notch of the wheel sleeves, thereby causing the shackle to be locked.
