Abstract
A padlock includes a shackle attached to a lock housing, a lever pivotally disposed in the lock housing and having one end for anchoring legs of the shackle to the lock housing, a carrier slidably received in the lock housing and having an actuating member to selectively disengage the lever from the legs of the shackle and having a number of protrusions. A follower is slidably attached onto the lock housing, and includes an anchoring device to anchor the carrier to the lock housing at selected positions. An operating device includes a number of selected bars slidably attached onto the lock housing, to actuate the protrusions of the carrier, and to move the carrier relative to the lock housing step by step.
Claims14
A padlock comprising:
- a lock housing including a chamber formed therein, and including two longitudinal channels formed in side portions thereof,
- a shackle including two legs slidably engageable into said channels of said lock housing respectively, and each having a notch formed therein,
- a lever pivotally disposed in said lock housing with a pivot pin, and including a first end for engaging into said notch of either of said legs of said shackle, to anchor said legs of said shackle to said lock housing, and including a second end,
- a carrier slidably received in said chamber of said lock housing, and including an actuating member provided thereon, for selectively engaging with said second end of said lever, and for rotating said lever relative to said lock housing, to disengage said first end of said lever from said notch of said legs of said shackle, and to allow said legs of said shackle to be disengaged from said lock housing, said carrier including a plurality of protrusions extended therefrom,
- a spring biasing means for biasing said actuating member of said carrier away from said second end of said lever,
- a follower slidably attached onto said lock housing, and including an anchoring device for engaging with said carrier, and for positioning and anchoring said carrier to said lock housing at selected positions,
- an operating device including a plurality of selected bars and non-selected bars slidably attached onto said lock housing, said selected bars being arranged to engage with and to actuate said protrusions of said carrier, in order to move said carrier relative to said lock housing step by step, and said non-selected bars being arranged to engage with and to actuate said follower, to selectively disengage said anchoring device of said follower away from said carrier, and to allow said actuating member of said carrier to be biased away from said second end of said lever by said spring biasing means.
