Abstract

A padlock has a shackle with a short leg and a long leg and a lock body having two partial channels to accommodate the short and long legs. Each of the short and long legs has a bolt groove to receive a bolt. The lock body also has a through channel for placing a spindle having a locking area and an unlocking groove. A plurality of dials and clutches mounted on the spindle control the spindle movement. When the padlock is in the locked mode, the spindle is located within the through channel such that the locking area pushes the bolts against the bolt grooves, preventing the shackle from being pulled upward. When dials match the combination code, the spindle can move upward to allow the bolts to move away from the bolt grooves toward the unlocking groove and the shackle can be pulled upward to unlock the padlock.
