Patent attributes
A multiple function lock comprising an engaging element and a captive element. The engaging element enters a captive space provided in the captive element for locking the lock. The captive element includes a selectable passage into the captive space for permitting the engagement element to be selectively released or secured. The selectable passage is revealed or concealed through translation or rotation of a blocking element. In certain embodiments, the multiple function lock comprises a body, a shackle having toe and heel portions, a first locking mechanism for securing the heel portion to the body and a separate second locking mechanism for securing the toe portion to the body. The second locking mechanism is operative to engage and disengage the toe portion from the body so the shackle may rotate about the heel portion secured by the body.
