A barrier device for a locking device is provided with a stator, with a rotor with a rotor axis and with an electromechanical actuator in the rotor. The rotor has two rotor elements, with the first rotor element and the second rotor element being arranged axially one behind the other in relation to the rotor axis. The two rotor elements are connected to each other in a rotationally fixed manner. The electromechanical actuator is arranged in one of the rotor elements. A locking device is provided with a locking device housing and the barrier device. The barrier device is received in the locking cylinder housing. In particular, the locking device includes a fastening element which is inserted from the outside into the locking device housing in order to fasten the stator to the locking device housing in a rotationally fixed manner.

A lock (1) is described, comprising: a body (2) suitable to define a housing (3) having a longitudinal development direction (L) along an insertion direction (I) of a key (200), said housing (3) comprising a first portion (4) and a second portion (5) mutually adjacent along the longitudinal development direction (L) of the body (2); a first rotor (37) suitable to be rotationally housed within the first portion (4) of said housing (3) of such body (2) about the longitudinal development direction (L) of the body (2), said first rotor (37) being suitable to define a further housing (38); a second rotor (39) comprising a first portion (55) suitable to be rotationally housed within the second portion (5) of said housing (3) of the body (2) about the longitudinal development direction (L) of such body (2), said second rotor (39) comprising a second portion (56) suitable to be rotationally housed within the further housing (38) defined by the first rotor (37) about the longitudinal development direction (L) of such body (2). The second rotor (39), by the insertion of the key (200), is suitable to translate along the longitudinal development direction (L) of the body (2) with respect to the first rotor (37). The second rotor (39), by a first rotation portion of the key (200), is suitable to rotate about the longitudinal development direction (L) of the body (2) with respect to the first rotor (37), to pass from a disengagement position to an engagement position with said first rotor (37). In the engagement position, said first rotor (37) and said second rotor (39), by a second portion of rotation of the key (200), are suitable to integrally translate along the longitudinal development direction (L) of the body (2) to reach an actuating position of the lock (1).

A barrier device for a locking device is provided with a stator and with a rotor as two components and with a barrier element. The rotor is mounted in the stator. The barrier element is mounted in a first component of the components and can be moved between a first position and a second position. In the first position, the barrier element engages in a second component of the components. In the second position, the barrier element is disengaged from the second component. The second component has a first contact surface for the barrier element, which moves the barrier element from the first position into the second position when the rotor rotates. The second component further has a second contact surface for the barrier element, which leaves the barrier element in the first position when the rotor begins to rotate. A locking device is provided with the barrier device.

A barrier device for a locking device is provided with a stator, with a rotor with a rotor axis and with an electromechanical actuator in the rotor. The rotor has two rotor elements, with the first rotor element and the second rotor element being arranged axially one behind the other in relation to the rotor axis. The two rotor elements are connected to each other in a rotationally fixed manner. The electromechanical actuator is arranged in one of the rotor elements. A locking device is provided with a locking device housing and the barrier device. The barrier device is received in the locking cylinder housing. In particular, the locking device includes a fastening element which is inserted from the outside into the locking device housing in order to fasten the stator to the locking device housing in a rotationally fixed manner.

The invention relates to a push-in-plunger-lock and housing-cylinder that facilitates an easy removal and installation of the push-in-plunger-lock as it attaches to a lockable device. Normally the push-in-plunger-lock can be mounted to a lockable device using two flanges with holes or threads on the lock being secured in place with a locknut ring. In certain particular applications of using the push-in-plunger-lock there is no suitable application to mount the lock other than metal welding the push-in-plunger-lock to the lockable device. One of these particular applications is mounting the push-in-plunger-lock on a ratchet chain binder to block the use of the U-pawl preventing the normal operational removal of the ratchet chain binder from a chain. The invention provides a housing-cylinder to insert the push-in-plunger-lock into while securing the lock in place with a pin. The pin can only be removed when the push-in-plunger-lock is in the unlocked position. The invention allows the push-in-plunger-lock to be easily changed and matched to keyed alike other push-in-plunger-locks instead of re-keying the push-in-plunger-locks or allowing the replacing of a defective push-in-plunger-lock that would involve grinding the defective push-in-plunger-lock from the lockable device and metal welding a replacement push-in-plunger-lock onto the lockable device.
