The invention relates to a method for securing and/or locking an object. At least one metal key element (1.1) which is at least partly provided with at least one coding along the longitudinal direction of the key element is introduced into a key receiving area (2.2). The first coding is read by means of a reading device (3.2) in the key receiving area (2.2). A method is provided in whichthe key element (1.1) is rotated in the key receiving area (2.2) relative to the key receiving area by a user, thereby generating a relative rotational movement, the relative rotational movement is detected, the detected relative rotational movement is converted into a display signal which varies with the rotation, the display signal is imparted to a display means (2.4) for displaying purposes, an additional coding is adjusted on the display means (2.4) in an interactive manner by means of the user by rotating the key element (1.1), and the securing and/or locking or unlocking process of the object (2.1) is actuated on the basis of the additional coding, wherein for securing purposes, an introduced coding can be used by means of a key element, and an additional coding can be used in an interactive manner with the user. A corresponding device carries out the steps using corresponding means.

A lock includes a housing, a cylindrical core body and a tumbler unit. The core body is rotatably mounted in the housing, and includes a core axle, and a core tube sleeved on the core axle. The core axle has a helical keyway. The tumbler unit includes a housing pin hole formed in the housing, a tube through hole formed through the core tube, a pin assembly movably mounted in the housing pin hole and the tube through hole, a hole-defining surface defining the tube through hole and having a shoulder surface portion, and a resilient member disposed in the housing and resiliently biasing the pin assembly to abut against the shoulder surface portion and extend into the helical keyway.

The invention relates to a closing system having a key (1.1) coded in a quantum-physical manner, which withstands very high mechanical forces, wear, or temperatures. The key consists, for example, of a solid stainless-steel bar having, for example, a diameter of 8 mm and, for example, a length of 120 mm. The coding of the key (1.1) is based on a quantum-physical solid body cryptography. The matter of the solid main body is partially changed in such a way that this change can be read out by means of read-out methods suitable therefor. The coding occurs into the depth of the main body such that external influences such as damage to the surface do not impair the function of the key. The quantum key processed in such a way has no visible or perceptible features of the coding. More than 500 billion different codings are accommodated on a length of approximately 50 mm. The locking system comprises a decoding unit on the lock for decoding the codings, which have been introduced into the solid metal of the key in a quantum-physical manner. The arrangement according to the invention offers a locking system that is extremely resistant to forgery and manipulation, on the basis of quantum-physical solid body cryptography.

A lock comprises: a body with a housing comprising a first and a second portion mutually adjacent along an longitudinal development direction corresponding to an insertion direction of a key; a first rotor with a further housing, rotationally housed within the first portion of the housing of the body; a second rotor comprising a first portion rotationally housed within the second portion of the housing of the body; a second portion rotationally housed within the further housing of the first rotor. The second rotor, inserting the key, translates along the longitudinal development direction of the body with respect to the first rotor and, by a first rotation portion of the key, rotates with respect to the first rotor, passing from disengaging to engaging the first rotor, wherein the first rotor and the second rotor, by a second portion of rotation of the key, integrally translate to actuate the lock.

A magnetic unlocking device and a magnetic unlocking structure of a magnetic encoding key. The magnetic unlocking structure includes a lock core device and a magnetic unlocking device. The lock core device includes a lock core casing, a lock knob which is provided in the internal cavity of the lock core casing, a lock care front end cover and a lock core rear end cover that are located at both ends of the lock core casing. The internal wall of the lock core casing is provided with a monad longitudinal moving groove and a monad horizontal rotating groove. The lock knob is provided with an unlocking hole. The external wall of the lock knob is provided with a monad longitudinal slide-way. The monad longitudinal slide-way and the monad longitudinal moving groove correspond to each other and form a monad moving cavity.

A lock includes a housing, a cylindrical core body and a tumbler unit. The core body is rotatably mounted in the housing, and includes a core axle, and a core tube sleeved on the core axle. The core axle has a helical keyway. The tumbler unit includes a housing pin hole formed in the housing, a tube through hole formed through the core tube, a pin assembly movably mounted in the housing pin hole and the tube through hole, a hole-defining surface defining the tube through hole and having a shoulder surface portion, and a resilient member disposed in the housing and resiliently biasing the pin assembly to abut against the shoulder surface portion and extend into the helical keyway.

A tumbler pin lock includes one or two auxiliary locking mechanisms including an auxiliary locking pin, and an auxiliary blocking component to provide enhance locking in addition to the locking provided by the tumbler pins so that the lock remains locked even if the tumblers are picked or bumped into their unlocked positions. A cylinder lock is provided with an auxiliary locking pin which projects into the keyway, which, with the proper key, is slid forward with a mobile device into an area in the lock housing where an auxiliary groove allows the cylinder plug to turn. The second locking component, which is approximately rectangular similarly has a post that is moved forward with the insertion of the proper key into an annular groove allowing the cylinder plug to turn.

A pickproof lock has a hollow housing, a lock shaft and a sleeve mounted in the housing, multiple axial pin sets mounted in the lock shaft and the sleeve, and at least one radial pin set mounted in the housing and the lock shaft. When unlocking the pickproof lock, the key is able to push the axial pin sets and the at least one radial pin set to unlocking positions, so as to drive the lock shaft to rotate and to unlock the pickproof lock. The complexity of the pickproof lock is increased. People with bad intentions are unable to unlock the pickproof lock with a lock picking tool, such as a round tube. Accordingly, personal goods or private matters can be safely protected by the pickproof lock.

A trapped key interlock system is disclosed. A pair of hollow tubular casings located one inside the other and each having a series of elongate slots are used. When the lock is in a locked condition the elongate slots are aligned as inner and outer pairs with engaging members extending through the pairs of slots is preventing rotational movement of the tubular casings relative to each other. The engaging members are biased towards this locked condition. On insertion of the correctly coded key the engaging members are caused to move against the biasing force out of engagement with the slots in the outer tubular casing thereby allowing the inner tubular casing to rotate relative to the outer tubular casing and moving the lock to an unlocked condition.

A dual-ring tubular lock assembly is provided. Inner and outer walls of a key are formed with inner-ring and outer-ring notches. A lock cylinder is inserted in a central through hole of a lock housing. A front end of the lock cylinder is formed with a tubular keyhole. The tubular keyhole is formed with inner-ring and outer-ring grooves corresponding to the inner-ring and outer-ring notches and mounted with inner-ring and outer-ring key pins. A rear end of the lock cylinder passes through a central perforation of a lower bead seat and extends out of the lock housing. The lower bead seat is fixed in the center through hole. The lower bead seat is formed with inner-ring and outer-ring holes corresponding to the inner-ring and outer-ring grooves and mounted with inner-ring and outer-ring driver pins and springs. The latch is fixed to the rear end of the lock cylinder.
