A shackle-equipped lock with shielded shackle includes a housing enclosing a locking mechanism and a top wall with first and second bores therein. There is a shackle comprising a shaft and an inverted, generally U-shaped clasp, with the shaft lower end adapted for making locking engagement within the first bore and its upper end making a hinge joint with a first end of the clasp. The other end of the clasp is adapted for making locking engagement within the second bore, and in an unlocked condition the clasp is pivotable at the hinge about an axis which is perpendicular to the plane in which the shackle generally lies. A protective shield having a front wall, rear wall and spaced apart side walls, extends upwardly from the housing top wall, and surrounds the bores, and the front wall is spaced sufficiently from the second bore to allow the unlocked lower end of the clasp to pass when it is pivoted open.

A high security hasp-enshrouding lock for securing together a pair of companion locking bars having adjacent apertured hasp portions projecting outwardly in parallel abutment, the lock having a lock body providing with a rearwardly opening cavity to receive the alined abutting hasp portions therein shielded over most of their extent by the lock body and having a shackle bar on a pivoted shackle lever movable transversely through the cavity and hasp apertures to lock the hasp portions against withdrawal. The locking mechanism within the lock body includes a pivoted hasp clamping member along one side of the cavity having a rear portion projecting from the lock body to intercept wedge type attack tools during attempts to wedge the lock from the schackle and having a contact surface defining a side portion of the cavity. The schackle lever is moved between locked and unlocked conditions by a cylindrical actuating member movable between raised and lowered positions and having a key lock plug therein and locking pin means coactive with the housing to lock and release the cylindrical actuating member. The contact surface of the hasp clamping member is rotated toward the hasp portions to clamp them tightly against the opposite wall portion of the cavity when the hasp clamping member is moved by wedge type attack tools.

A wafer padlock has a lock body, a limiting wafer, multiple locking wafers, and a shackle. The limiting wafer and the locking wafers are arranged in the lock body at spaced intervals. One of two ends of the shackle is selectively engaged with the lock body, and the other one of the two ends of the shackle is inserted in the lock body and extends through the limiting wafer and the locking wafers. The wafer padlock is unlocked by inserting a key into at least one key hole formed in the lock body. There is no need to turn the key and no need to enter code numbers one by one. Unlocking of the wafer padlock is quick and convenient. The wafer padlock has simple structures and high security for locking items.

A portable lock includes a wireless signal receiver. The lock may be unlocked by transmitting a wireless unlock signal from a portable device such as a cellular telephone. Various actuation mechanisms which may include a solenoid, motor or memory wire of a type that contracts when energized are provided in example embodiments. Self-locking embodiments are readily operated with one hand.

A dual locking padlock having a code locking mechanism and an overriding mechanism is disclosed. The housing has a top body, a stack of dials and clutches mounted on a bottom body, and a spindle engaging with the clutches. The spindle has a channel to store the heel of a shackle. An upward movement of the spindle allows the shackle to be pulled upward to unlock the padlock. Each dial has a plurality of teeth with slope-like surfaces to engage with the wave slots of a clutch. Clutches are rotatable relative to the spindle only when the lock is in the locked mode along with the dials. In the opened mode, a dial can be turned relative to a clutch by disengaging the teeth from wave-slots. The spindle is allowed to move upward either when a correct combination code is used or when a key activates the overriding mechanism.
