Abstract: A surface-mountable locking system is designed to secure an item to a surface via one or more mechanical engagements that are protected from tampering by encompassing the engagements point(s) within cavity-defining surfaces. In one example the mechanical engagement is effected by placing a pin in a box and securing the pin in the box using a bolt and the tampering protection is effected by the surfaces that define the box. In another example, the mechanical engagement is effected by placing a surface-attached anchor within a cavity and securing the anchor relative to the cavity using a bolt and the tampering protection is effected by the surfaces that define the cavity. The securing bolt may be, for example, the bolt of locking mechanism, a threaded bolt to engage a receptacle having complementary threads, or a smooth bolt to engage a receptacle having a shape complementary to that of the bolt.

Abstract: A surface-mountable locking device includes a body within which is disposed: (1) a box configured to receive a pin and (2) a locking mechanism having a bolt configured to engage the pin when the pin is inserted into the box. Because the locking-mechanism bolt engages the pin within the box disposed in the body, the body protects the locking-mechanism bolt from tampering, creating a more secure lock than when the bolt is exposed. An adapter for attaching a chain link (or similar link) to the locking device is also disclosed. The adapter is configured on one end as a pin to engage the box and on the other end to engage a link.
