Description

DESCRIPTION

A) The proposed invention is part of the field of automatic mechanisms for use in the industrial and construction fields, suitable for locking and / or unlocking of movable walls, external and internal frames, doors in general of doors and gates, shutters, all swing or sliding, roller shutters, tilting shutters, sliding shutters with horizontal or vertical translation.

B) In the current state of the art, to the best of my knowledge, the locking and / or unlocking in opening and closing of the elements referred to in point (A) takes place exclusively through manual mechanical systems such as lever, handle, key with lock, produced in various types and models: recessed and not, with or without single central latch, equipped with single or double bolt of different sizes; or electrically operated only for. central single latch locks. In each product currently on the market, the mechanism can be inserted and activated on one side of the door in general, in a horizontal or vertical position and each closing line corresponds to a single command point.

C) The invention consists of an electromechanical mechanism that can be recessed into the upright (s) and horizontal or oblique crosspieces capable of ensuring optimal locking and / or unlocking of the closure through the simple contact of the leaves equipped with corresponding electrical terminals . In particular, it should be noted that the aforementioned mechanism can be inserted into the profiles in aluminum, steel, PVC, wood or any suitable support. When the electrical contact has been made, the motor activates two opposing rack rods which, sliding in special guides, insert the rods and latches in the appropriate housings, activating the locking and therefore the closure. To unlock and allow opening, simply activate the mechanism with the button on the electrical system and / or remote control which starts the mechanism in reverse.

The technical problem and the relative advantageous effects that can be overcome with this mechanism are:

the overcoming of the manual action that is carried out today on the current locking and unlocking mechanisms;

- the possibility of activating several locking / unlocking points arranged along the perimeter of the single lock with a single non-manual command;

the freedom to shape the door or any element to open / close in any shape as long as it has sides of such length as to allow the mechanism to be housed;

the possibility of arranging the mechanism on all sides of the door or just some of them;

- the locking and / or unlocking command of several locks arranged in parallel;

- the combination with any electromechanical or manual door closing system for doors and windows arranged at heights that are not easily accessible.

The electric impulse generated by the switch and / or remote control activates the motor (C) which drives the two opposing rack rods (E); these, sliding in the appropriate guides (G), through the leaf thrust spring fN}, activate the movement of the latches (F) which rotate around the pin (L) taking them to an orthogonal position for transverse locking; at the same time the rack rods (E) push the rods (P), arranged in axis with the rods (E) as a continuation of these, into the housing for locking in the longitudinal direction. The presence of the limit switch (H) controls the shutdown of the motor (C). To unlock and open it is sufficient to command the system button and / or remote control which activates the mechanism in reverse. In particular, the motor (C) draws the rods (P) from the locking position through the rack rods (E) which simultaneously act on the return springs (l) of the latches (F) which, rotating around the pin (L) they lead to a longitudinal position allowing unlocking and therefore opening. When the rods (E) and latches (F) return perfectly to the release position, the limit switch pin (D) and the limit switch (H) disconnect the electrical contact, stopping the motor (B). the system itself also has a "buffer" battery recharging circuit that allows it to work even in the absence of electricity. The mechanism and the electrical system are protected against overvoltages and overcurrents in compliance with current regulations.

It can be mounted on all the currents of the perimeter of the element to be blocked or only on one or some of them, however inclined with respect to the frame and in any case inclined to each other as long as they are alternatively staggered in such a way as to allow the terminal rods (P) to fit into the locked position without hitting each other. 3) Motorized electromechanical automatic mechanism according to the preceding claims which, by simply pressing on an external button placed at any distance or on a remote control, ensures the unlocking of the parts in contact. 4) Motorized electromechanical automatic mechanism according to the preceding claims equipped with a low voltage DC motor (B) (actuator) served by a suitably designed electrical circuit which controls the locking / unlocking by means of two N.A pulses which can be inserted in any support for systems residential electrical / industrial equipment.

The mechanism and the electrical system are protected against overvoltages and overcurrents in compliance with current standards. 5) Electromechanical automatic mechanism according to the previous claims characterized by the fact that inserted in the profiles of generic fixtures of any door leaf, with the manual or mechanical push action on the leaves with the aid of the switch and / or remote control, the electric impulse that starts the motor (B) fixed to the support (A) by means of the support (C), which, by rotating, acts on the rack rod (s) (E) causing their movement inside the guides (G) and consequently, the simultaneous synchronized movement of the end rod (s) (P) and of the latches (F) which stops when the limit switch pin (D) reaches the limit switch (H); moreover and in particular, the opening movement of the latches takes place with a rotation around the pin (M) thanks to the removal action caused by the leaf spring (N); the limit switch (H) through the contacts (S) stops the motor (B) which stops the system in the locking position. The system is placed in the unlocking position with the opposite movement to the locking one of all its parts which is activated by means of a switch and / or remote control; in particular, the return movement of the latches (F) is forced by the return spring (I); the simultaneous synchronized movement of the end rod (s) (P) and the latches (F) stops in the open position when the limit switch pin (D) reaches the limit switch position (H).

The entire lock relating to the latch (F) is not mounted. 8) Electromechanical automatic mechanism according to the preceding claims with single locking realized only with the latches (F) activated by the motor (B) which are inserted centrally to one of the uprights allowing the stop and the locking.

All can be controlled in locking or unlocking with a single electrical impulse which simultaneously activates the motors (B) of each single mechanism, with obvious advantages in relation to safety windows. 9) Electromechanical automatic mechanism according to the preceding claims which can be coupled to all the electromechanical systems for closing the hinged or sliding or tilting doors using the same electric command and suitably interfacing the relative system. 10) Electromechanical automatic mechanism according to the preceding claims which can be mounted in intermediate position, single or multiple, of articulated and non-articulated movable walls, roller or tilting shutters, horizontally articulated and non-articulated shutters.
