Padlock assembly
First Claim
1. A padlock comprising:
- a lock body;
a shackle assembled with the lock body;
a lock subassembly disposed in a cavity in the lock body and operable between a locked position securing the shackle in a closed position and an unlocked position permitting movement of the shackle to an open position; and
a shackle retaining pin assembled with the lock body, the shackle retaining pin including a first end portion having a first diameter and a second end portion having a second diameter smaller than the first diameter, the first end portion being disposed in a first shackle bore and received in a recess in a first leg of the shackle disposed within the first shackle bore, the second end portion extending into a cross-bore in the lock body, the cross-bore intersecting the first shackle bore and the cavity;
wherein when the shackle is in the open position, the lock subassembly is manipulable to be moved from a first position to a second position to align an empty portion of the cavity with the shackle retaining pin, such that the second end portion of the shackle retaining pin is extendable into the empty portion of the cavity for disengagement of the shackle retaining pin from the first shackle leg recess, thereby permitting removal of the shackle from the lock body, with the first end portion of the shackle retaining pin abutting a shoulder surface in the cross-bore to prevent the first end portion of the shackle retaining pin from entering the cavity.

Abstract
A padlock includes a lock body, a shackle assembled with the lock body, a lock subassembly disposed in a cavity in the lock body, and a shackle retainer assembled with the lock body. The lock subassembly is operable between a locked position securing the shackle in a closed position and an unlocked position permitting movement of the shackle to an open position. The shackle retainer extends into a first shackle bore and is received in a recess in a first leg of the shackle. When the shackle is in the open position, the lock subassembly is manipulable to be moved from a first position to a second position to generate a space in the cavity aligned with the shackle retainer, such that the shackle retainer is extendable into the space for disengagement of the shackle retainer from the first shackle leg recess.

1. A padlock comprising:
-
a lock body; a shackle assembled with the lock body; a lock subassembly disposed in a cavity in the lock body and operable between a locked position securing the shackle in a closed position and an unlocked position permitting movement of the shackle to an open position; and a shackle retaining pin assembled with the lock body, the shackle retaining pin including a first end portion having a first diameter and a second end portion having a second diameter smaller than the first diameter, the first end portion being disposed in a first shackle bore and received in a recess in a first leg of the shackle disposed within the first shackle bore, the second end portion extending into a cross-bore in the lock body, the cross-bore intersecting the first shackle bore and the cavity; wherein when the shackle is in the open position, the lock subassembly is manipulable to be moved from a first position to a second position to align an empty portion of the cavity with the shackle retaining pin, such that the second end portion of the shackle retaining pin is extendable into the empty portion of the cavity for disengagement of the shackle retaining pin from the first shackle leg recess, thereby permitting removal of the shackle from the lock body, with the first end portion of the shackle retaining pin abutting a shoulder surface in the cross-bore to prevent the first end portion of the shackle retaining pin from entering the cavity. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. A method of removing a shackle from a lock body of a padlock, the method comprising:
-
moving a shackle within a first shackle bore of the lock body to an open position; with the shackle in the open position, moving a lock subassembly disposed in a cavity in the lock body from a first position to a second position to generate a space in the cavity in alignment with a shackle retaining pin having a first end portion at least partially disposed in the first shackle bore and within a recess in a first shackle leg disposed within the first shackle bore, and a second end portion extending into a cross-bore in the lock body, the cross-bore intersecting the first shackle bore and the cavity; with the lock subassembly in the second position, moving the second end portion of the shackle retaining pin into the cavity space until the first end portion of the shackle retaining pin abuts a shoulder surface in the cross-bore, thereby disengaging the shackle retaining pin from the recess in the first shackle leg; and with the shackle retaining pin disengaged from the recess in the first shackle leg, withdrawing the first shackle leg from the first shackle bore to remove the shackle from the lock body. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of assembling a padlock, the method comprising:
-
providing a lock body defining first and second shackle bores, an internal cavity, and a cross-bore intersecting the first shackle bore and the cavity; providing a shackle retaining pin in a shackle releasing position having a first end portion at least partially disposed in the cross-bore intersecting the first shackle bore and the cavity and a second end portion extending into the cavity, with the first end portion abutting a shoulder surface in the cross-bore; with the shackle retaining pin in the shackle releasing position, inserting a long leg of a shackle into the first shackle bore to align a first end of a recess in the long shackle leg with the cross-bore; with the long leg of the shackle inserted in the first shackle bore, moving the shackle retaining pin into a shackle retaining position such that the second end portion is withdrawn from the cavity into the cross-bore and the first end portion is received within the long shackle leg recess; with the retaining pin in the shackle retaining position, inserting a lock subassembly into the cavity; and with the lock subassembly inserted into the cavity, securing the lock subassembly to the lock body. - View Dependent Claims (19, 20, 21)
