<< AUTOMATIC LOCKING SYSTEM APPLICABLE ON SHUTTERS AND SHUTTERS

ROLLING SHUTTERS >>

The present invention relates to an automatic locking system which can be applied to roller shutters and shutters, in residential, commercial and industrial applications.

The process of continuous technical/regulatory updating, which started in 2011 with the introduction of CPR 305/2011, i.e. the regulation of construction products in the European Union, has focused the market's attention on the performance of both blackout closures, such as shutters, and technical closures, such as rolling shutters.

Among the services recently requested? counted the resistance to? Theft or the capacity? of said closures to resist break-in interventions by criminals. This performance is now evaluated according to the UNI EN 1627:2011 standard, inherent to pedestrian doors, windows, curtain walls, railings and swinging closures, for which they are standardized, in addition to the related characteristics of resistance to burglary, their classification requirements. This standard therefore indicates the classification requirements based on burglary resistance tests conducted on typological models of doors, windows, gratings and shutters. The classification ranges in a range between the numerical values ?one? and ?are you? on a scale of increasing values: for example a product in class ?are you? ? characterized by maximum safety, while in class ?one? it is less secure against burglary attempts.

The difference between the individual anti-burglary classes? growing in correlation to the characteristics of the means used in the break-in attempt and the attitude of the thief.

In particular:

? the class ?one? foresees that an occasional burglar who tries to force the door, the window, or the shutter closed using small tools and physical strength by means, for example, of kicks and shoulders, probably without knowing the real resistance of the product, even if he pays attention to the times and to the noises, as well as? to avoid major risks;

? the class ?two? provides that the burglar tries to force the window, the door or the locking system with rudimentary tools such as screwdrivers, pincers or wedges, without using tools capable of piercing and having basic knowledge of the resistance of the security system, placing, also? close attention to times and noises, as well as not to take high risks;

? the class ?three? provides that the burglar, to break into the locking system, uses a crowbar and at the same time a screwdriver, hand tools and mechanical drilling tools suitable for damaging the locking means, possessing general knowledge of the sealing means of the locking means and placing attention to noise and technical times, being willing to take only medium-sized risks;

? the class ?four? foresees that the expert burglar, in addition to being able to use all the tools listed in the previous classes, uses hammers, hatchets, chisels and portable battery-operated drills, being also willing to take a greater risk. high, being more noisy said means that can be used for burglary;

? the class ?five? foresees that the expert burglar uses, in addition to power tools, such as drills, also saber saws and angle grinders with a maximum disc of one hundred and twenty-five millimeters in diameter, which considerably increase the possibilities of burglary; said burglar? now otherwise? sufficiently motivated and discreetly organized, as well as willing to bear considerable risks, given the high noise level? of the equipment used;

? the class ?are you? requires the burglar to be an expert in the sector, capable of using more powerful electric tools, for example drills, saber saws and angle grinders with a maximum disc of two hundred and thirty millimeters in diameter, i.e. tools with a high level of effectiveness, even if used by a single person, the latter being very organized and motivated, as well as not at all concerned by the noise produced and willing to take very high risks.

After the previous overview illustrating the break-in classes in a complete way, ? possible to better understand how important it is to develop a passive security system tailored to the type of application and the context for which the locking system ? been designed and/or chosen.

The combination of more security products can for example, greatly lengthen the times of the burglary attempt, inducing the criminal to surrender.

The means currently used to give rolling shutters or shutters better resistance to burglary consist of locks or bolts operated manually by the user.

Are there also inherent blocks in the unit? of motorization or anti-lifting systems applied in the upper part of the mantle.

By way of example, mention is made of the patent application commercially denominated ?SIPAR? and filed with number IT102018000010031, which concerns a central lock block equipped with a servomotor for activating the anti-theft bolts, which block requires a specific power supply with twenty-four Volt power supply voltage, which is? strictly necessary to install on the mobile leaf, with the relative triggering of the unwanted electrical risk.

? otherwise? note also the application commercially denominated ?PREFER?, of which at the moment it is not ? possible to know the relative patent application, but what ? possible to deduce through the video film at the web address https://www.youtube.com/watch?v=hVzUQtnq16U, through which ? It is possible to deduce a power supply cable for the servomechanism for activating the bolts, similar to the previous patent commercially denominated ?SIPAR?.

From the patent search carried out in the UIBM database, similar applications did not appear, having searched for patents deposited by the main national producers of locking systems for doors (PREFER ? VIRO ? MOTTURA ? POTENT). From this prior art search, no applications similar to the present one developed by other manufacturers at EU and non-EU level appear, having searched the European database for keywords such as: ?lock system for shutter?, ?door lock?, ?bolt?, ? electric lock?.

From this search carried out ? the only result was a patent filed by in particular the patent IT102018000010031, which is, however, totally different from the present invention.

Furthermore, all said known anti-burglary devices have the drawback of being not very effective against the burglar? If the motorisation is activated, he ends up forgoing the application of the same devices or, at most, their manual engagement. Purpose of the present invention ? that of overcoming said limitations of the prior art, creating in an innovative way a mechanism which activates automatically in the limit switch position of the roller shutter, not being subject to any intervention by the operator and thus being able to guarantee always, as well as? seamlessly, the effectiveness of its application, for the purpose cos? also to increase the burglary resistance class of the locking system.

Another object of the present invention, which also makes it inventive, ? that of definitively solving the problem related to the difficult activation of the current locking systems, such as, for example, the manual locks and bolts, which, often being at a height close to that of the floor level, are inactivable or, in any case , not easy to activate, especially by disabled users.

The object of the present invention is, therefore, to solve said problems and drawbacks of the prior art, by devising and realizing an automatic locking system applicable to rolling shutters and shutters, in residential, commercial and industrial applications, which is characterized precisely by the no need for power supply cables on the leaf, as it does not have servo-mechanisms that move the locking bolts.

Another object of the present invention, certainly no less important than the previous ones, is that of also guaranteeing the legislative and regulatory requirements established by the harmonized product standards, in particular:

? CPR 305/2011 (?EU construction products regulation?);

? 2006/42/CE (?Machinery Directive?);

? UNI EN 13659 (?Blackout closures and external Venetian blinds - Performance requirements including safety?);

? UNI EN 13241 (?Industrial, commercial and garage doors and gates - product standard, performance characteristics?).

An additional purpose? also inherent in the fact that the closure must never imprison the user and that dangerous situations such as to compromise the user's health must never arise.

Another important purpose? to predict the possibility? to manually unlock the mechanism using the key lock block.

These aims are achieved by realizing an innovative and valid automatic blocking system S applicable to roller shutters and shutters, in residential, commercial and industrial applications, according to what is claimed at the bottom of the present description and described below.

Said purposes and the consequent advantages, as well as the characteristics of the invention according to the present invention will be more? clearly evident from the following detailed description of a preferred solution, given by way of non-limiting example with reference to the attached drawings, in which:

- Fig.1 ? an image showing a three-dimensional view of the present automatic locking system S applicable to rolling shutters and shutters, in residential, commercial and industrial applications, from which ? possible to deduce, with a view inside the shutter, the beach 1 to which? applied the closure means or lock 2 and the side profile 9 for anchoring the guide;

- Fig.2 ? an image showing a side view of the same automatic locking system S as in Fig.1, where the right side? the one facing the internal side, closed by the shutter;

- Fig.3 ? an image showing a three-dimensional view of the same automatic locking system S as in Fig.1, where ? now it is possible to deduce also the internal lateral guide 8;

- Fig.4 ? an image showing a bottom plan view of the same automatic locking system S as in Fig.1;

- Fig.5 ? an image showing a front view from the internal side of the same automatic locking system S as in Fig.1, in which ? the detail P has been highlighted with a circumference;

- Fig.6 ? an image showing a top plan view of the same automatic locking system S as in Fig.1;

- Fig.7 ? another image showing, in a three-dimensional view and again from the inside, the same automatic locking system S as in Fig.1;

- Fig.8 ? a further cross-sectional image of the same automatic locking system S in Fig.1, now showing the inner part of the damper on the left;

- Fig.9 ? a further image showing, in a three-dimensional view and again from the inside, the same automatic locking system S as in Fig.1;

- Fig.10 ? a first image showing the slightly enlarged detail P referred to in Fig.5, from which the modality? closure of the lock 2, by inserting the small cylinder 4 constrained to the bolt 3 inside the seat of the rotating hook 10;

- Fig.11 ? an image now showing, in a three-dimensional view and still from the inside, the same automatic locking system S as in the preceding Fig.10;

- Fig.12 ? an exploded three-dimensional view image of the automatic locking system S according to the present invention, from which ? now it is better possible to deduce all the single components of the same system S and to deduce the simple modalities? by Assembly; - Fig.13 ? a further three-dimensional view of the automatic locking system S, from which its operation during the closing of the damper can be seen from its internal side;

- Fig.14 ? a further image, now in a frantal view of the automatic blocking system S, from which for an expert in the art ? it is easy to deduce, from its internal side, its functioning, once the damper has closed;

From the fourteen figures attached hereto below and showing a preferred but non-limiting solution of the innovative idea, an expert in the art can easily deduce how the present invention brilliantly solves said limitations of the prior art, in that it concerns an innovative and valid automatic locking system S applicable to roller shutters and shutters, in residential, commercial and industrial applications, provided with a high resistance to burglary or rather an automatic blocking system S conferring an? excellent capacity? to the closure to which it is applied in order to resist any burglary interventions carried out by ill-intentioned people.

The mechanism of the present automatic locking system S is therefore activated automatically in the limit switch position of the rolling closure, not being subject to any intervention by the operator and thus being able to always guarantee the effectiveness of its application in order to increase the burglary resistance class of the closure.

The present invention S is characterized in that it has eliminated the need to install electrical power wiring on the door as they are no longer? needed, how? possible to deduce in particular from the exploded view of Fig.12.

The present invention S is further characterized in that it has a pair of electromagnetic induction servo-mechanisms suitable for keeping the bolt 3 locked and/or unlocked, provided with a small cylinder 4 for locking it.

Said servo-mechanisms are in particular constituted by the coupling: - of a proximity sensor? by electro-magnetic induction 20 of the rotating hook 10 to the cylinder 4;

- a proximity sensor? by electro-magnetic induction 19 of block 11 with magnetic latch on cylinder 4;

Cylinder 4? constrained to the bolt 3 by means of a screw or locking pin 5 of variable length according to the guide.

As ? possible to deduce from the attached drawings, in particular from the exploded view of Fig.12, the bolt 3 ? sliding horizontally inside the lock 2 of the traditional and, therefore, known type, applicable by means of a set of screws or pins 6 with relative nuts 7 to the rail 1 of the shutter, on which, in correspondence with the constraint axes (indicated with thin lines dash-dot) of said screws 6 as many holes have been made, in addition to one, with a larger diameter, necessary for the application of the external side of the patch 23, through the hole of which ? It is possible to lock the damper from the external side (as well as ?, however it is also possible to do it from the internal side of the damper).

The beach 1? constituted, as known, by a metal element shaped like a curl 22 at the top to be able to be hooked to the first upper slat of the mantle constituting the rolling shutter or damper to which it is connected. applied, as well as by a terminal element or rib 21, able to resist the contact stresses of the covering of the closing system in the floor abutment phase.

The rotating hook 10, as well as the block with magnetic latch 11, can be secured on the internal side of the ?L? 9, suitable in turn for anchoring the guide shaped like a ?U? 8.

The rotating hook 10 ? consisting of a metal element provided with a recess 24 suitable for the sliding inside it of the cylinder 4 rigidly constrained to the bolt 3 by means of the locking screw 5, said sliding taking place during the opening and closing phases of the roller shutter. The rotating hook 10 ? otherwise? provided with a hole necessary for its hinging constraint on the ?L? 9 via a hexagonal head screw 17 and a threaded insert 18.

A pair of hexagonal-head threaded screws 15-16 rigidly constrains a leaf spring 14, the latter able to keep the rotating hook 10 elastically constrained, when the latter is released. rotated by approximately ninety degrees under the lowering action of the bottom rail 1 (as shown, with the arrow pointing downwards, in Fig.14, where the arrow indicates the lowering direction of the rolling shutter), thus guaranteeing closure of the roller shutter.

One of the two hexagonal head threaded screws 16 ? also equipped with a milling to allow a perfected elastic operation of the spring in its locking and unlocking action of the rotating hook 10.

Said rotating hook 10 ? made up of a metal profile shaped like a stirrup with an L? cross section? 9 and ? elastically hinged on said stiffening profile 9, through the insertion in one of its holes of a screw 17 with a threaded insert 18.

Said elastic hinge? obtained by means of the leaf spring 14, the latter being constrained to the ?L? 14 and able to carry out, together with the combined stress of the block 11 with magnetic latch 25, the action of constraint and release of the small cylinder 4 from its hooking seat 24 longitudinally obtained in said rotating hook 10.

The proximity sensor? electro-magnetic 20 positioned adjacent to the rotating hook signals that the automatic system S has blocked.

In case of reopening of the rolling shutter, system S, through the block with magnetic latch 11, gives a lifting impulse (and, therefore, rotation and release of the cylinder 4 from said constraint seat 24 present in the rotating hook), through its latch 25 consisting of a vertically sliding wedge-shaped bolt.

The proximity sensor? electro-magnetic 19 placed adjacent to the block with magnetic latch 11 signals that the automatic system S has been released.

Obviously ? Is it possible to install these proximity sensors? electromagnetic signals 19-20 in such a way as to invert said signals or create further and possible installation configurations of the elements constituting the present invention.

The block with magnetic latch 11 ? in turn equipped with electric power supply microcables 12 terminating in an electric terminal 13 (female) to which ? possible to insert an electric terminal suitable for its electric power supply.

From what has been described, depicted and exhibited, an art technician can easily deduce how the? activity? invention contained in the present invention, is inherent in the fact that it has devised a locking system S, which can be applied to a motorized rolling shutter or shutter, which is activated automatically during the closing phase and deactivated during the opening phase, the drives of which do not require power supply integral with the leaf. Proximity sensors located in the mechanism control the locking and unlocking of the closure. Only when the mechanism ? in block status, the unit? control deactivates the flashing light, communicating to the user the safety status of the mobile leaf, made up in this case by the mobile side rail in the vertical direction (downwards when closing and upwards when opening). Only during the opening phase, therefore, and only after the blocking lever, constituted by the leaf spring 14, has been released, does the unit? command ? enabled to operate the gearmotor, eliminating any possible unsafe starting of the latter.

Thereby ? possible to guarantee the fact that the closure can never imprison the user, as well as being capable of not creating, during its operation, dangerous situations such as to compromise the user's health;

The main advantage is, therefore, constituted by the fact of having inserted a pair of electro-magnetic induction sensors for the electronic control of the deactivation of the mechanism before the activation of the geared motor.

A further advantage is, moreover, represented by the fact that ? it is always possible to manually unlock the mechanism through the key lock block.

A further advantage of the present invention with respect to the prior art? represented by the fact that the rotating hook ? able to block the bolt cylinder in a completely automatic way;

A further and undoubted advantage? constituted by the fact that it also solves the problem of the difficult activation of the current locking systems (manual locks or bolts), which, being often located at floor level, are inactivated by users with disabilities.

The further advantages, no less important than the previous ones, derive from the further innovative aspects of the present invention, namely the fact that:

? The blocking means of said rotating hook ? consisting of a block with latch operated by a magnet;

? The control device of said block with latch? been created by inserting proximity sensors;

? The rotary hook engagement control device ? also made using proximity sensors, capable of deactivating the flashing light (not shown in the attached drawings) signaling movement of the rolling shutter, communicating to the user that the mechanism has been blocked;

? The sealing in closure and the facilitation of the release of the rotating hook ? guaranteed by the leaf spring, designed to keep the rotating hook in closing thrust and at the same time, under the release action of the magnetic latch, to release the cylinder located on the bolt;

? The manual release of the mechanism? equally guaranteed by the retraction movement of the bolt rod, under the manual action of the double bit key inserted in the lock.

? it is also clear that numerous adjustments, adaptations, additions, variations and replacements of elements with other functionally equivalent ones could be made to the embodiment previously described by way of non-limiting example, without departing from the scope of protection of the following claims.
