A padlock is provided that can be locked and unlocked using a combination mechanism or a key mechanism. A padlock includes clutches that will not be turned during the lock mode or the open mode. A lock body has more than one slot to engage an extended fin of the clutch in the lock mode. An opening slot and faulty notches are located in each of the dials. In the lock mode, the turning of the dials will have no effect on the clutches. Each extended fin of the clutch is engaged in a slot of the lock body in the lock mode. The faulty notches on the dials are clearer and an intruder cannot feel the correct opening slot by turning dials to pick the combination.

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 group of embodiments for enabling the replacement of damaged shackles for multiple types of portable locks is disclosed. The embodiments have the ability to alter the shackle size and configuration for multiple types of portable locks by substituting one type of shackle with a different shackle, with no tools or special skills required.

This invention involves a novel method, device, system and apparatus to receive, return or exchange packages and goods securely, and to monitor and control a parcel receptacle remotely. The invention comprises of a DoorBox and a Smart DoorBox and utilizes a parcel receptacle and a host of electronic features and Internet of things (IOT) technologies. The security, apparatus is connectable to any fixture, including to one or more parcel receptacles. The parcel receptacles can be secured via a physical cable and a security apparatus, or secured via connectivity to a wireless network. The parcel receptacles can also be secured via a 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 IOT and other wireless technologies, or alternatively, involve simple locking mechanisms. The apparatus allows access to parcels to authenticated users only and involve many safety features including an audible alarm, mobile-app alerts, camera and a host of advanced features. The parcel receptacle can be integrated with smart home systems and can have a host of security features to monitor, alert any intruders.

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.

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.

An electronic lock includes a lock body and a shackle selectively securable via one or more ball bearings. An asymmetric cam can be rotated by a key or an electric motor to: a locked state in which the ball bearing secures the shackle within the lock body via at least one lock notch in the shackle, an unlocked state in which the ball bearing is released from the lock notch to unlock the shackle and subsequently engages a revolved notch on a distal end of the shackle to prevent removal of the shackle from the lock body, and a removal state in which the ball bearing is released from the lock notch and the revolved notch to allow the shackle to be removed from the lock body. A shackle detector can detect a shackle in the locked state. Externally accessible electrical contacts allow for jumpstarting a discharged battery.

U-shaped locks are provided with an external shell made from a relatively soft metal that clogs grindings disks and reduces their cutting effectiveness.

An exemplary shackle is configured for use with a crossbar having a pair of openings and a locking mechanism including a pair of deadbolts. The shackle includes a substantially flat plate portion having a length in a longitudinal direction, a width in a transverse direction, and a thickness along a lateral axis defining a proximal direction and a distal direction. The length is greater than the width, which is greater than the thickness. The shackle further includes a pair of longitudinally-offset legs extending distally from the plate portion. Each leg has a diameter, and includes a bumper and a notch positioned distally of the bumper. An offset distance is defined between the distal surface of the plate portion and the distal faces of the bumpers. The width of the plate portion is greater than each of the diameter and the offset distance.

Described herein are systems and apparatuses for securing and locking a ride-able board to a fixed object. In general, a ride-able board may optionally include a planar body configured for moving across a solid surface and for carrying a rider. In general, a ride-able board may include a planar body mounted to a steering apparatus and any number of wheels. In a preferred embodiment, the security device containing a shackle and housing comprising an open cavity is used to secure the board to any fixed object. In a preferred embodiment, the housing cavity slides over the steering apparatus and has two openings for each end of the shackle. The lock secures the shackle in place and prevents the removal of the board from the fixed object. The housing working in conjunction with the u-shackle prevents removal of the locking device from the board.
