Padlock cylinder retention
View Patent ↗A padlock with a removable lock cylinder. A retaining member couples the lock cylinder to the padlock's body. In some embodiments, the retaining member includes a flange for actuating the retaining member between a retained position and a released position. The flange is accessible through an opening of the lock body when the shackle is in the unlocked position and inaccessible when the shackle is in the locked position.
1. A padlock comprising:
a body;
a shackle movable relative to the body between a locked position and an unlocked position, wherein the shackle includes a first arm movably installed within a first opening of the lock body, wherein the shackle includes a second arm retained within a second opening of the lock body in the locked position and movable out of the second opening of the lock body in the unlocked position;
a lock cylinder within the lock body;
a retaining member movable between a first position that couples the lock cylinder with the body and a second position that releases the lock cylinder from the body;
wherein the retaining member includes a flange for actuating the retaining member between the first position and the second position, wherein the flange is accessible through the second opening of the lock body when the shackle is in the unlocked position and the flange is inaccessible when the shackle is in the locked position;
wherein the retaining member is movable between the first position and the second position about an axis transverse to a longitudinal axis of the lock cylinder;
wherein the retaining member includes a first leg and a second leg extending from the flange;
wherein the first leg and the second leg engage the lock cylinder when the retaining member is in the first position; and
wherein at least one of the first leg and second leg include a laterally extending bump.
2. The padlock as recited in claim 1 , wherein the body defines a slot that extends transverse to a longitudinal axis of the lock cylinder, wherein the retaining member is movable between the first position and the second position within the slot.
3. The padlock as recited in claim 2 , wherein the slot includes at least one recess configured to receive the bump when the retaining member is in the first position.
4. The padlock as recited in claim 3 , wherein the flange includes one or more recesses for gripping the retaining member.
5. A padlock comprising:
a body;
a shackle movable relative to the body between a locked position and an unlocked position, wherein the shackle includes a first arm movably installed within a first opening of the lock body, wherein the shackle includes a second arm retained within a second opening of the lock body in the locked position and movable out of the second opening of the lock body in the unlocked position;
a lock cylinder within the lock body;
a retaining clip comprising a first leg and a second leg extending from a flange, wherein the retaining clip is slidable between a first position in which the first leg and the second leg engage the lock cylinder to couple the lock cylinder to the body and a second position that releases the lock cylinder from the body;
wherein the flange of the retaining clip is accessible through the second opening of the lock body when the shackle is in the unlocked position and the flange is inaccessible when the shackle is in the locked position; and
wherein the first leg and the second leg include a laterally extending bump.
6. The padlock as recited in claim 5 , wherein the body defines a slot that extends transverse to a longitudinal axis of the lock cylinder, wherein the retaining member is movable between the first position and the second position within the slot, wherein the slot includes at least one recess configured to receive the bump when the retaining member is in the first position.
