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.

Claims

1. Improved padlock for securing a latching member, comprising:

(a) main case having a bottom, spaced-apart side walls and an upper wall with at least one shaft-receiving bore therein, said walls enclosing a locking mechanism, and including portions of said side walls that extend upwardly beyond said case upper wall and that surround said at least one bore, and said upper wall having an upper face providing a first shaped portion for engaging a latching member;

(b) latching head, disposed above said main case, and having at least one shaft-like connecting member fixedly attached to said head and extending from the bottom of said head into said at least one bore to make lockable engagement and limited axial movement therein, said head having outer wall portions that are slidably embraced within said upwardly extending side wall portions of said case for guiding said head in vertical movement relative to said case and for shielding said at least one shaft-like connecting member, and said latching head having a lower face providing a second shaped portion for engaging a latching member;

(c) wherein said padlock has a locked position in which said at least one shaft-like member is locked within said case and said first shaped portion lies in close proximity to said second shaped portion, and said latching head being releasable to an open position in which said first and second shaped portions are spaced apart wherein said first shaped portion is contoured with a first arcuate groove, and a second arcuate groove lies in said second shaped portion, and said first and second grooves adapted to grasp and hold a U-shaped member when said padlock is in locked position, and

a third arcuate groove in said second shaped portion, and wherein when said padlock is in locked position, said first, second and third grooves are adapted to grasp and hold a U-shaped member in a first orientation with respect to said padlock in which said first and second arcuate grooves grasp said U-shaped member, or in a second orientation at about 90°

to said first orientation in which said third arcuate groove grasps said U-shaped member.

2. Padlock as defined in claim 1 wherein said first and second grooves are oriented at about 90°

to said third arcuate groove.

3. Padlock as defined in claim 1 wherein said main case has a generally flat front wall and said latching head has a generally flat top, and said first and second arcuate grooves lie in a plane which is generally perpendicular to said front wall, and said third arcuate groove lies in a plane which is generally perpendicular to said top.
