In one aspect of the present disclosure, a locking device is provided including an interchangeable core (IC), a barrel, an anti-rotation plate, a prong driver, a bolt and a backplate. The barrel is coupled to the backplate and includes a hollow interior to receive the IC. The bolt is slidably disposed in a slot of the backplate. The IC includes a key hole. The prong driver is coupled to the IC and the bolt, such that, when a proper key is inserted into the key hole and rotated the bolt can be extended from the slot in a direction away from the locking device or retracted into the slot in a direction toward the interior of the locking device. The anti-rotation plate of the locking device is coupled to the barrel to prevent the locking device from being rotated relative to a structure the locking device is mounted to.

The invention refers to a lock system consisting of a hub cap (1), with a decentralized hole (2) for key insertion (3), where the lid (1) has appropriately inclined levels of pin pressure (7) and a key (8). The lid (1) is rotatable and it pushes a roller (21) through the sloping pin pressure level (7) which is located on the upper side of the lid (19) which pushes down a cluster of springs (15), (18) from locking (16) and alignment (17) pins, in order for the latter to align, allowing the case (9) and the hub (10) to rotate. At the same time, the rotation of the lid (1) pushes the key (3) inside the hub (10) in order to engage the two gears (24), (30), which will allow, through a knob (28), the opening of the latch bolt (26).

A pick-resistant lock assembly is provided. The lock assembly includes a housing having a main bore and a chamber including a plurality of channels holding a corresponding plurality of pin stacks, a core having a keyway and having a plurality of core openings configured to align with the channels of the housing, and a sleeve configured to fit within the main bore. The pin stacks are each configured to provide a plurality of decoy shear lines in which rotation of the core and the sleeve together is limited by a blocking position and a true shear line which permits rotation of the core and the sleeve together for actuation of the lock assembly when the true shear line is provided in each pin stack of the plurality of pin stacks.

The invention provides a lock body having a keyway and a throughbore parallel to the keyway with the throughbore having two portions separated by a shoulder. A first cable passes through the throughbore, the first cable having a knob at one end and a chevron at a second end. A second cable depends from and is attached to the lock body. The cable body also has a bolt that is biased partially into the first portion of the throughbore. The keyway has a plug that is rotatable with the proper key to retract the bolt from the throughbore. The chevron can pass by the bolt in an axial first direction by urging the chevron and allowing the taper to move the bolt transversely against the bias, but not in a second axial direction. A base accommodates the lock body and cables and is captured by the second cable.

A folding lock comprises a folding plate assembly, a lock seat, a fixing sleeve, a lock core seat, a lock core, a connecting swivel, a lock column, and a fixing collar. A fixed folding plate of the assembly is provided with a connecting seat, the lock seat is disposed on the connecting seat and provided with an insertion hole, an inlay protrudes from the insertion hole, the fixing sleeve inserts into the connecting seat and disposes in the lock seat, the lock core disposes in the lock core seat, the connecting swivel is assembled on the lock core seat, a torsion spring disposes between the lock core seat and the connecting swivel, the lock column is assembled on the connecting swivel, a compression spring is sleeved on the connecting swivel and the lock column, and the fixing collar is disposed in the fixing sleeve.

The invention relates to a cross-sectional profile (1) for a flat key or the keyway of a cylinder lock, comprising a back surface (2), a first lateral surface (4) and a second lateral surface (4′), wherein the lateral surfaces (4, 4′) extend in the vertical direction to the back surface (2), the lateral surfaces (4, 4′) are arranged offset to one another by a distance (5), which varies along their extension, and the outline of the cross-sectional profile (1) defines a preferably substantially rectangular base profile (6), and wherein the lateral surfaces (4, 4′) each extend at least in sections along sinusoidal profiling lines (7, 7′), wherein the centerlines (8, 8′) of the profiling lines (7, 7′) lie within the base profile (6). Further, the invention relates to a flat key (16) with such a cross-sectional profile (1) and a cylinder lock with a keyway (13) for receiving such a flat key (16).

A bumping preventing arrangement (10) for a lock device (38, 52, 68), the bumping preventing arrangement (10) comprising transfer member (12, 46, 64, 74) having a magnet (14), the transfer member (12, 46, 64, 74) being movable along an actuation axis (18) between a locked position (16) and an unlocked position (36); a plurality of electric conductors (20), each electric conductor (20) enclosing the actuation axis (18); and a plurality of switches (22), each switch (22) being associated with a respective electric conductor (20), and being arranged to selectively close an electric circuit comprising the associated electric conductor (20) such that eddy currents are induced in the electric conductors (20) when the magnet (14) moves along the actuation axis (18) from the locked position (16) towards the unlocked position (36). A lock device (38, 52, 68) and a method of controlling a lock device (38, 52, 68) are also provided.

A security system with multifactor authentication, and may comprise a lock assembly configured to secure an object and having a secured condition and an unsecured condition, a lock actuating element for actuating the lock assembly between the secured and unsecured conditions, a first authentication structure configured to permit actuation of the lock assembly by the lock actuating element when authenticated by the first authenticating structure, and a second authentication structure configured to permit actuation of the lock assembly by the lock actuating element when authenticated by the second authentication structure, so that authentication by the first authentication structure and the second authentication structure is required to actuate the lock assembly.
