ABSTRACT:
An improved padlock having a main, generally rectangular case with walls that enclose a locking mechanism, and including a top wall with at least one shaft-receiving bore, and the case having side wall portions that extend upwardly beyond the case top wall and surround the at least one bore, and the top wall having a portion that is shaped for grasping. A latching head is disposed above the main case to which it is connected by at least one shaft extending from the latching head through the at least one bore for lockable engagement with the locking mechanism. The upwardly extending wall portions of the case slidably embrace the outer surface of the latching head to shield the at least one shaft and to guide the latching head in limited vertical movement from a padlock open position, in which a shaped portion of the latching head lower wall is spaced apart from the shaped portion of the case top wall, to a locked position in which these shaped portions are brought together. An opening in the case side wall allows for insertion of an article to be secured, such as a latch member having an end portion that is adapted to be lockably engaged by the aforementioned shaped portions.
