ABSTRACT:
A combination padlock includes: a plurality of magnifying lenses juxtapositionally mounted on a lock body of the padlock with each lens projectively corresponding to each numeral formed on each dial so that the numeral formed on each dial can be magnified by each magnifying lens for a clear reading by a user's eyes; and a hasp pivotally mounted in a side portion of the lock body of the combination padlock having an arcuate hook member operatively lockable with a hasp socket recessed in a projecting portion extending upwardly sidewardly from the lock body in an opposite direction of the arcuate hook member of the hasp for locking an object or a staple within the hasp with a wider angular movement of the hasp. The lock can be conveniently operated with one hand to not only rotate the dials and lock and unlock the hasp, but also to move the hasp into its fully open or locked positions. The magnifying lenses are integrally formed with a transparent cover assembly which is locked around the lock body by a portion of the hasp.
