It is characterized in that: a) the casing has a longitudinal plane of symmetry; b) two tongue stops opposite the coins and a dog engaging with one or both tongue stops are provided, the three elements being arranged on the same pivoting axis; c) the tongue has an opening with a notch with which the ends of the dogs interfere when the tongue is displaced in the absence of coins, and with an end seat for said ends when the tongue is displaced in the presence of coins; d) below the opening and on each side of the tongue there are respective fixed stops and respective movable stops which are coupled together by means of a positioning lever driven by the tongue via a pin on which it is able to pivot.

Abstract: Locking system for furniture drawers, including a rivet attached to the drawer which operates a locking device, all these locking devices are correlated through a base-plate fitted to the piece of furniture. The drawers have a height (H) such that this is a multiple of a predetermined dimension (d1). Each locking device includes a rocker, for actuation by the rivet, incorporated in a one-piece element bearing a surface cam for the rivet and a T-shaped back projection for sliding thereof in the base-plate. The height (m) of the one-piece element is such that the predetermined quantity (d1) is a multiple of said height (m); in such a way that the one-piece elements of the system interlock. The rivet is positioned at a distance (Z) from the side that is a multiple of the height (m) of the one-piece element.

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: A programmable electronic lock with a closing tongue is actuated with an actuating mechanism formed by a mobile knob acting as a button joined to the closing tongue. Actuation of the mobile knob generates a movement of the closing tongue and closure of the lock. Recovery of the mobile knob to its initial position generates an opening of the lock. Furthermore, an electronics board is activated with a transponder key and controls operation of the lock by deactivating and subsequently activating a blocking mechanism formed by a motor that actuates a punch via a gear mechanism. When the punch is in a blocking position it is located against the actuating mechanism. When the punch is in an unblocking position, it is separated from the actuating mechanism and allows the movement of the closing tongue by unblocking the actuating mechanism.

Abstract: The invention relates to an electronic blocking module for closing systems with a casing (1) internally having a blocking mechanism (2) which prevents or allows the opening of a closing system, and which is controlled by an electronics board (3), which communicates with an external electronic control system which transmits signals to it for blocking and unblocking the closing system, and receives from it signals of the position of the blocking mechanism (2). The electronics board (3) comprises at least a first microswitch (4) and a second microswitch (5) which detect the movement towards the blocking and unblocking position of the blocking mechanism (2), and a third microswitch (6) detecting the blocking and unblocking position of the blocking mechanism (2), transmitting it to the electronic control system.

Abstract: Master-keyed pin tumbler lock and relative master-key, where each pin has an inner window with an outer protuberance, which a spring acts upon and an inner projection, which the key acts upon, giving rise to the movement of the pin. The inner projections are at different heights and the pins are placed so that some move in one direction and others in the opposite direction, each pin having, in its inner window, a step placed on the opposite side to that of the inner projection. On one of the sides of the key there is a notch whose minimum width is the distance between the maximum level reached by the projections of the pins that move in one direction and the maximum level reached by those of the pins that move in the opposite direction; on the opposite side they have a double serration combined with the steps of the inner windows of the pins.
