The present invention, in a non-limiting example embodiment provides a locking apparatus and method for securing locking hardware without the use of a key. In an example embodiment, the apparatus comprises at least a keyless insertion rotatable disk-style, barrel locking apparatus that, in a locked state can be inserted into a securing device without first unlocking, and then, thereafter, locking after insertion. In a nonlimiting example embodiment, unlocking and re-locking requires a key. The present invention, in an example embodiment, also provides features that allow the locking apparatus to enter and exit multiple apertures without requiring a key.

Certain embodiments described herein are directed to locks that include one or more cylinder members effective to deter removal of a lock cylinder. In some configurations, the cylinder member is configured to engage a circumferential surface of the lock cylinder to deter removal of the lock cylinder on circumferential rotation of the lock cylinder. In other instances, the cylinder member is configured to etch the lock cylinder upon circumferential rotation of the lock cylinder.

A door lock includes an outer enclosure constituted by a body that is substantially shaped like a flattened parallelepiped. The lock has a hole passing through the enclosure, with an axis of extension that is perpendicular to the base of the body, and is suitable for the insertion of a double handle unit. The lock further includes a spring latch exiting from a side wall of the body, through an opening, the spring latch being connected to the edge of the through hole and adapted to be actuated by the handle unit. The lock includes a seat for a cylinder, of the mortise type, the latter provided with an end cam and being accessible from the side of the enclosure that is adapted to correspond to the outside of the door, the cylinder being adapted to release the lock.

A handle assembly includes a lock cylinder of a selected one of a first standard or a different second standard. A tail piece extends from the lock cylinder. The handle assembly also includes a vertical tubular member, a horizontal tubular member and a transition plate. The transition plate is disposed within the vertical tubular member and is moveable between a first position and a different second position. The transition plate accommodates installation of the lock cylinder of the first standard when in the first position and installation of the lock cylinder of the second standard when in the second position. A mechanical linkage is coupled to the tail piece and effects movement of a locking bolt in response to turning of a key in the lock cylinder.

A door handle assembly includes a bracket mountable to the door and an insertion member received in and retained in the bracket via a retaining mechanism. The retaining mechanism includes a biasing member and a movable locking member that retains the insertion member in the bracket. The movable locking member is biased into a securing position by the biasing member when the insertion member is fully received in the bracket to retain the insertion member in the bracket. The movable locking member is selectively displaceable from the securing position against a force of the biasing member either to permit insertion of the insertion member in the bracket during assembly or to accommodate disassembly by permitting the insertion member to be removed from the bracket.

A cylinder-lock assembly configured to allow affixing accessories that are designed to be operatively coupled with a standard European locking cylinder to operate an American mortise type lock system. The cylinder-lock assembly includes a cylinder-lock-member that includes a cylinder-housing having an external shape of a European cylinder-housing, and a cylindrical lock core. The cylinder-housing defines a cylindrical through bore configured to receive the cylindrical shaft, and the cylindrical shaft is adapted to rotate there inside the cylinder-housing. The cylinder-lock assembly further includes an adapting-ring, a cylindrical American housing and a rotation-conveyor, configured to operatively convey rotational motion of a fitted key, which is disposed inside the cylindrical shaft, to an American-lock type cam, to thereby actuate the door lock/unlock mechanism of the American type mortise lock.

A lock insert for a cylinder lock is disclosed for locking an electric switch, including a main part with an opening for receiving the cylinder lock. In an embodiment, the inner wall of the opening is designed to at least partially contact an outer wall of the cylinder lock, and in the inner wall at least one slot is formed to allow freedom of radial movement of locking elements in the cylinder lock, the positions of which correspond to a locked position of the cylinder lock.

The present invention relates to a safety device for locks including a casing with a system for entering an opening code, a cylinder for activating the lock, and a dial, fixed to the casing with capacity of rotation, and firmly attached to a tab which blocks opening based on the position in which it is located by means of a connecting part and the cylinder, the tab being firmly fixed to the cylinder. The dial includes a drive bushing firmly fixed to the cylinder by means of a connecting part, and a cover bushing including a flange, for fixing to the inside of the casing, and a gripping area projecting from the casing to activate the tab, wherein the cover bushing is fixed to the drive bushing by pressure.
