Abstract: 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.

Abstract: A lock (1) with an exterior activation sensor (2) includes an interior electromechanical mechanism (3) with a corresponding power supply unit (4) and an exterior activation sensor (2) situated on the external part of the locker, and which is used in community lockers or similar, wherein the exterior activation sensor (2) contains at least two respective internal electrical contacts (5) which, by means of a conductive circuit (6), reach the inside of the lock and connect in parallel to the interior poles of the circuit (4a) of the power supply unit (4).

Abstract: Interchangeable cylinder for locks that have an outer cylinder and an inner cylinder that has a locking device that uses a master key to unlock it is provided. The object of the invention is the inner cylinder, which carries an associated wing in functions of a handle, the wing and the body of the cylinder forming a single whole. The wing is integrated in the cylinder itself, and is extended radially beyond its body. The wing is of thin, flat or extra-flat configuration, and is attached to or integrated into the front of the cylinder itself. For application in interchangeable cylinder locks, to comply with ADA regulations.

Abstract: A locking system with infrared communications includes a lock (1) and a programming key (2). The lock (1) includes an interacting device (3) for interacting with the user, a first communications module (4) having an infrared sensor which receives and sends information when communications with the key (2) is established. A first control module (5) manages the received information and a mechanical device (6) opens and locks the locking system a first warning (7) and a first power supply (8). The programming key (2) includes a second communications module (10) including an infrared sensor for communicating with the lock (1), a second control module (11), a storage module (12), a second warning (13), a connector for connection externally (14) and a second power supply (15).

Abstract: The invention relates to a lock comprising a lockable knob, formed by a closure tongue (1) non-rotatably mounted on the shaft of a cylinder (2) which rotates in a casing (3) under the action of a knob (4). The knob (4) is mounted on the cylinder (2) and casing (3) such that it can move linearly between two end positions, namely an operating position and a locked position. The casing (3) and the knob (4) include at least two geometrically arranged linear guides (33, 43) which, during the linear movement of the knob (4), are engaged with, or released from one another. In addition, the cylinder (2) and the knob (4) include radial openings (20, 40) which are positioned coaxially in the locked position and offset axially in the operating position. The cylinder (2) and the casing (3) include geometrically arranged cams (22, 32) which limit the rotational movement of the cylinder (2) in the casing (3) between the tongue (1) -opening and -closing positions.

Abstract: An electronic lock includes optical detection for detecting an enabler (card or coin), including an inserter (1) for allowing the introduction of an enabler (2) in the lock (10); a retainer (5) for retaining the enabler (2) in a reading position; an optical detector (4) for detecting the enabler (2) when it is introduced in the reading position; an interactive device (7) for capturing a user access information; a control module for receiving and verifying the access information and the information from the optical detecotr (4) and if both verifications are correct, generating a signal for operating the lock.
