A padlock comprises a lock body and a hoop, in particular a flexible hoop, which has a first hoop end. In this respect, the lock body has a first hoop receiver in order to selectively receive the first hoop end therein. The lock body further comprises a blocking element which is displaceable between a blocked position in which it blocks the first hoop end against an exiting from the first hoop receiver and a release position in which it releases the first hoop end for an exiting from the first hoop receiver. The lock body furthermore comprises a drive element which is rotatable between a locked position in which it locks the blocking element in its blocked position and an unlatched position in which it permits a displacement of the blocking element into its release position. The drive element in turn comprises a rotary body and a latch element which is displaceably supported at the rotary body, with the latch element being preloaded toward the blocking element in the unlatched position in order to secure the blocking element against an automatic displacement into the release position.

A wireless ultra-low power portable lock may be realized as a lock apparatus including: a locking mechanism having at least locked and unlocked states, the locking mechanism operable to provide physical resistance to being unlocked when in the locked state; an actuator operable to move the locking mechanism from the locked state to the unlocked state in response to a received signal; and a controlling unit configured to control the actuator and to receive one or more signals from one or more devices external to the lock apparatus.

A hoop lock including a shackle and a crossbar, with the shackle having a pair of legs extending from a body portion, and each of the legs having a foot including a tip with a non-circular cross-section. The cross-bar includes a housing having a pair of foot-receiving openings and a pair of tip-receiving openings substantially aligned with foot-receiving openings. The tip-receiving openings are configured to matingly engage the tips such that the tips are rotationally coupled to the housing.

An electronic lock has a lock body and a hoop that can be selectively locked to the lock body or released from the lock body. The lock body comprises an electromechanical locking device having a cam rotatable about an axis of rotation and the hoop comprises a first introduction section that can be introduced into the lock body and having a lower holding section and an upper locking notch. The cam is configured, in a locking rotational position, to engage into the upper locking notch of the first introduction section and to lock the hoop to the lock body; in an unlocking rotational position, to release the upper locking notch and to hold the first introduction section at the lower holding section; and in a removal rotational position, to release the lower holding section of the first introduction section and to thereby release the hoop for a complete detachment from the lock body.

A keyed or combination cable lock for securing one or more cables or a lock shackle is presented. The lock secures one or both ends of a single cable or one end each of two separate cables when locked. Alternatively, the lock can secure one or both ends of a lock shackle. When the lock is unlocked, the secured ends can be removed from the lock by activation of a control knob. The lock is also able to a secure a section of a single slidable cable or two sections of a single slidable cable so that the lock can be slid down the slidable cable[s] in first direction when the lock is locked or unlocked, but the lock can be slid down the slidable cable[s] in the opposite direction only when the lock is unlocked and a control knob is activated.

An exemplary lock apparatus generally includes a shackle, a crossbar, a lock device, a first bolt, and a trigger. The lock device has a locked state in which the lock device retains a spindle in a spindle locking position, and an unlocked state in which the lock device does not prevent movement of the spindle to a spindle unlocking position. The first bolt is engaged with the spindle such that movement of the spindle between the spindle locking position and the spindle unlocking position drives the first bolt between a first locking position and a first unlocking position. The trigger is movably mounted in the crossbar for movement between an engagement position, in which the trigger maintains the spindle in the spindle unlocking position, and a disengagement position, in which the spindle is operable to move to the spindle locking position.

A lockable enclosure includes a housing and an access door assembled with the housing and movable between a closed position and an open position. A latch is carried by the access door and is slideable along a first axis between a door latching and a door releasing position. A plurality of dials are carried by the access door and rotatable about a post extending along a second axis. When each of the plurality of dials is rotated to an unlocking orientation, an outer peripheral recess on each of the dials aligns with a corresponding dial engaging portion of the latch, allowing the latch to slide along the first axis from the door latching position to the door releasing position.

A U-lock including a U-shaped shackle that includes two legs extending from a bow, the legs being received in a locked orientation in apertures formed in a crossbar, and a lock mechanism coupled to the crossbar for locking the legs with the crossbar. At least one of the legs and the bow of the U-shaped shackle has a cross-sectional shape of a polygon which has flat sides and none of the flat sides are parallel to each other.

This invention involves a novel method, device, system and apparatus to receive return or exchange goods and services at one's doorstep securely. The invention involves a novel security apparatus and a parcel receptacle. The security apparatus is connectable to any fixture, including to one or more parcel receptacles. The parcel receptacles can be of many types. The parcel receptacles can be secured via a physical cable and a security apparatus, or secured via connectivity to the wireless network of a parcel recipient. The parcel receptacles can also be secured via a novel GPS module, accelerometer and other technological devices inside parcel receptacle. The locking mechanism in the security apparatus and/or on the parcel receptacle can be of technological in nature using the latest advancements in wireless technology, or alternatively, involve simple physical lock and key mechanisms. The apparatus allows access to parcels to authenticated users only, and involve many safety features including an audible alarm and other tamper-proof mechanisms to ensure safety of parcels.

A pressurized chemical theft deterrent device includes a locking portion and a shackle. The locking portion includes a locking mechanism. The shackle includes a shackle wall. The shackle is configured to house a chemical deterrent within the shackle wall. The chemical deterrent is pressurized while being housed inside the shackle such that a breach in the integrity of the shackle wall causes an aerosolized release of the chemical deterrent.
