The present invention relates to a security locking system of the type comprising a cylinder (3) provided with a set of pistons (8) that are able to be positioned by elastic means on the impression formed in the edge (7b, 7c) of a control key (7) perpendicularly to the direction in which said key (7) is introduced into the cylinder (3), these pistons (8) being able to take up two positions, namely a position retracted into the cylinder (3) when the key (7) is introduced into the latter and an extended position when the key (7) is withdrawn there from. This system is characterized in that:—the cylinder is made up of a locking block (3) of parallelepipedal shape that is able to be received in a receiving block (5),—it comprises locking means which are activated when the locking block (3) is introduced into the receiving block (5).

Systems and methods for controlling access to a secured space are disclosed. The system includes a locking device having a body having a rotatable locking cam having a locked paddle and an unlocked paddle. The cam is rotatable between a first position and a second position. The body also has a locking pin and a power supply for supplying electrical power to circuit components of the locking device. The locking device also includes a shackle having two arms. One of the two arms has a groove in a bottom portion thereof configured to engage with the locking pin when the shackle is in a closed position. In the first position, the locked paddle of the rotatable locking cam engages the locking pin in the groove. In the second position, the locked paddle of the rotatable locking cam is disengaged from the locking pin.

Examples of devices are described herein. In some examples, a device may include a plurality of electronic elements. In some examples, each of the electronic elements is mechanically interlockable to another of the electronic elements. In some examples, each of the electronic elements is to control a lock state based on a broadcast signal to modify a shape of the device to a predetermined target shape.

The electronic actuator of an electronic padlock according to the invention is arranged to turn the cam piece (5) to release the latch parts (7) from a locking state and to turn the cam piece (5) to hold the latch parts (7) in the locking state. The cam piece (5) comprises a cover part (5A) and a shaft part (5B). The cover part has a central hole (12) for the shaft part. The shaft part (5B) has a shaft pin (15), which is set into the central hole (12). The shaft part also has a connecting part 19, which is arranged to be in contact with the electronic actuator 4. The cam piece further comprises a spring (9) which is between the shaft pin (15) and the cover part (5A). The spring comprises a first end (9A) and a second end (9B). The first end 9A is arranged to be in contact with the cover part 5A. The second end 9B is arranged to be in contact with the shaft part 5B. The spring is arranged to transmit turning force of the electronic actuator from the shaft pin 15 to the cover part 5A in the direction of said locking state.

The lock(100) comprises a controller, a data storage device, a lock mechanism operable by the controller in a locked state or an unlocked state, and a data communication frontend comprises a first data port(108) and a second data port; Wherein the controller is configured to enter into data communication via second data port after successful completion of data communication via the first data port(108). An electronic key(200) comprises a key controller, a data storage device, a power source and a data communication frontend comprising a first data port(202) and a second data port; wherein the electronic key(200) is a physical key having a key body and is configured to work with the lock(100).

A locking system has a housing and a spring positioned in a body. The system has a locking element on which a spring is attached such that the locking system is inside the housing, and provides locking. At least one fixing element is engaged with the housing, and enables the locking element to be fixed to the housing. At least one guide element is combined with the locking element, and allows the spring to remain on the locking element and the locking element to move in the housing. At least one ring is connected with the guide element and the locking element and ensures the fixation of the locking element to the housing.

The disclosed invention relates to a padlock comprising a U-shaped-shackle. The invention discloses a sleeve that fits tightly, mostly covering or surrounding a portion of the straight portion of the shackle-toe and wherein the sleeve also fits loosely and mostly covering or surrounding a small portion of the U-shaped-shackle-head nearest the shackle-toe. The sleeve being designed to deter a jawed manual bolt-cutting tool from cutting apart the shackle-toe of a padlock that comprises a U-shaped shackle. The sleeve also being designed large enough to be prevented from being pulled through the hole, staple, or link the padlock shackle is secured therein, therefore, mandating the shackle-toe remains in the hole, staple, or link the shackle-toe is secured therein. After cutting the shackle-heel or the shackle-head apart and wherein a portion of the U-shaped shackle-head remains attached to the shackle-toe, the disclosed invention sleeve will remain secured in place on the shackle-toe as any curved portion of the shackle-head will not allow the sleeve to slide off of its position on the shackle-toe, therefore, the padlock remains locked and secured in place.
