Description

The invention falls within the technical sector of high-security locks according to claim 1.
The need to combat increasingly skilful and evolved burglars and safebreakers does not permit respites in the search for increasingly better technical solutions so as to raise the security standard of the locks, whose inviolability often remains a relative value rather than absolute as by contrast is desirable.
In the field of mechanical locks, double bitted keys by now emerge as definitively outdated, even if recently ameliorative devices have been introduced, while the state of the art is today represented by the cylinder with a consolidated European profile, better if supplemented by magnets in the key. In order to externally protect the keyhole, the afore-mentioned locks with European cylinder are usually equipped with the so-called "defender", comprising a half-shell protection device, which incorporates an idle rotating bush in front of the keyhole, with anti-drill functions, while the body of the protection device is studied form-wise to prevent it being possible to enter a tube or pipe used as leverage to break said protective device and/or the cylinder. And then there are mechanical locks which are combined with complementary electromechanical or electronic devices which increase the security of the same, for example registering attempts of housebreaking and sending signals, and/or operating ancillary mechanisms aimed at blocking the lock in an irreversible manner with the normal key.
In addition to these, there are keyless mechanical locks, for example featuring combination dials such as those on safes, and also keyless electronic locks, featuring keypads with alphanumeric combination, or with transponders, cards with embedded chips (for example those used for hotel rooms), or further still featuring fingerprint recognition or, for the most sophisticated versions, iris recognition.
The aspects mentioned above represent, as is obvious, just an indication of the various types of lock on the market, since a more complete scrutiny would be extremely vast and essentially not particularly useful for contextualising the technical problem which it is intended be resolved with this invention.
In essence, the common denominator of the locks of a predominantly mechanical nature lies in the fact that there is a key, to be introduced in the related keyhole, more or less protected but accessible from outside, where the same key, if bearing the correct combination, acts directly for unblocking the mechanism linked to the retention devices, such as bolts, and controls the rotation in the direction of opening or closing.
Practically, the key represents both an opening device and a protection system; if one manages to bypass the latter, the lock is violated.
Also certain types of cylinder with European profile, especially the most economic models, have been forced with skill: without going into the merits of the various lock-picking techniques and/or devices, mention is made of just the so-called "bumping" which involves delivering small and repeated axial blows to a lock-picking key profiled if necessary, while the rotation is forced, so as to make the pistons of the combination hole pop out and find the opening combination.
For domestic or office applications, it becomes necessary to guarantee - for the lock - unflinching reliability, which does not require maintenance or periodic controls, limiting the presence of electrically-powered parts as far as possible, compatibly with the degree of security one wishes to obtain.
The purpose of this invention is therefore that of proposing a keyed device for operating locks, in particular combinable with euro profile cylinders, for example featuring the European profile, which makes it possible to overcome the traditional construction concept of known locks, which sees the key as the mechanical connection device which receives the manual act and directly transmits the opening (and/or closing) action to the mechanism, in this way avoiding all the inconveniences and risks associated with security which afflict the afore-mentioned well-known locks.
Another purpose of the invention involves envisaging a lock which is inaccessible from outside, and also protected against attacks of elevated force, in particular for that which concerns the area in which the particular key of the device presents its cuts to the mechanical combination means which must attest to the compliance, so as to permit the subsequent opening manoeuvre.
Another purpose of the invention concerns the desire to prevent any action aimed at the reverse detection of the correct combination cut of the key, thanks to the afore-mentioned inaccessibility of the area.
A further purpose of the invention envisages that the parts tasked with the passive protection of the lock, or rather those exposed to attack with devices such as drills, cutting disks or similar, can be suitably scaled, and in a variable manner according to the degree of resistance desired, as well as made of material appropriately treated to resist the cutting and/or drilling action.
Another additional purpose of the invention aims to obtain a key which can be contaihed and protected in a portable element, with said key destined to be detached from the latter so as to be inserted, in a retractable manner, in the device which is suitable for being operated by the same portable element, grasped like a device.
These and other purposes are fully achieved by means of a keyed device for operating locks, in particular incorporating euro profile cylinders, suitable for installation on security doors, armoured doors and the like, comprising at least one cylinder-operated deadbolt and a euro profile cylinder in which a cam can be rotated in either direction, respectively to open or close at least one deadbolt, since the following is envisaged in said device:

one mechanism for operating the cam comprising: an actuator plug situated inside the euro profile cylinder and coaxial with the rotation axis of the cam, which causes the cam to rotate; a manipulator head, connected to the actuator plug, and which causes the plug to rotate; mechanical combination means for blocking and releasing the rotation of the manipulator head and the connected actuator plug;
an opening/closing assembly, accessible from the exterior of the security doors, armoured doors and the like, for operating the manipulator head and the mechanical combination means, where the opening/closing assembly comprises: an outer shell, incorporating an axial pass-through cylindrical seat that houses a rotor coaxial with the manipulator head and the actuator plug, where the rotor is able to slide axially toward the manipulator head, in opposition to the spring-loaded components which retain it, when at rest, against a shoulder within the cylindrical seat; a defender block, for impeding external access to the manipulator head, supported by a pin inside the rotor, with the ability to rotate on an axis perpendicular to the rotation of the rotor, where the defender block is partially accessible externally and close to the manipulator head with its corresponding internal part, and where the defender block comprises a first profiled face that can be stably paired with a removable flat key, and a second profiled fade, diametrically opposite to the first, that can be provisionally paired with a locking/unlocking device, and where the defender block is able to rotate between at least two characteristic positions, one where the first profiled face is turned outward and can receive the flat key, and another where the first profiled face is turned toward the manipulator head white the second profiled face is turned outward and can receive the locking/unlocking device, which can be manually operated on to achieve: the axial translation of the rotor - defender block - flat key assembly, so that the key engages with the mechanical combination means for releasing the rotation of the manipulator head; the rotation, in one or the other direction, of the rotor-defender block - flat key - manipulator head - actuator plug assembly, with consequent rotation in the same direction of the cam to open or close the lock.

The features of the invention will emerge as clear from the following description of a preferred form of realisation of the keyed device for operating locks in question, in accordance with the matters indicated in the claims and with the aid of the attached drawings, in which:

In the afore-listed drawings, the keyed device for operating locks in question is indicated, in its entirety, using the reference 100.
The keyed device (100) is suitable for being associated with locks (S), in combination with euro profiled cylinders (E), in particular those with so-called "European" profile.
These locks (S), with the related cylinders (E), are suitable for being installed on security doors of homes and offices, armoured doors of safes or security lockers, and the like (not illustrated), and comprising at least one deadbolt (P) with lock operated by a cam (C) of the cylinder (E) (specifically see Dwg. 12).
The cam (C) is rotated in either direction, respectively to open or close said deadbolt (P), via the mechanisms of the aforementioned lock (S).
According to the invention, the device (100) includes a (1) mechanism for operating said cam (C), in which the following is envisaged:

an actuator plug (10) situated inside the euro profile cylinder (E) and coaxial with the rotation axis of the cam (C), causing the cam to rotate;
a manipulator head (11), associated with the actuator plug (10) and intended to rotate the latter;
mechanical combination means (12) for blocking and releasing the rotation of the afore-mentioned manipulator head (11) and the connected actuator plug (10).

The actuator plug (10) can slide axially, in opposition to the reaction of spring-loaded components (13), while the manipulator head (11) is inserted rotating in a cylindrical compartment (14) situated in a flange (15), with the latter integral to the afore-mentioned euro profile cylinder (E).
The mechanical combination means (12) are advantageously made up of a number of combination pins (120) (of which only two visible in Dwg. 3), housed inside said manipulator head (11) and arranged in a circle according to a predefined geometry, for example a circumference, with the respective axes parallel to that of the manipulator head (11).
The combination pins (120) protrude from the rear of the manipulator head (11) beyond the end of the cylindrical compartment (14) and are partially inserted into corresponding holes (16) situated in the flange (15); each of the combination pins (120) is made up of two consecutive parts, the first (121) and the second (122).
The total emerging length of each combination pin (120) can be the same or differ with respect to that of the remaining pins (120), as can the length of the first part (121) with respect to the second part (122), or with respect to those of the other pins (120).
In an alternative embodiment of the mechanical combination means (12), at least one of the afore-mentioned combination pins (120) includes a third part (123), for example a spheroid, placed between said first and second parts (121) (122) (Dwg. 3).
The insertion or removal of the third part (123) makes it possible, conveniently, to modify the combination cuts of the mechanical combination means (12) at a later stage.
Each combination pin (120) in two parts (121) (122) (or three), is subject to the action of the spring-loaded components (124) inserted in the related hole (16), which drive it axially to protrude from the front side of the manipulator head (11), up until a pre-established position defined by a stop (17) envisaged in the latter.
The device (100) also comprises an opening/closing assembly (2), accessible from the external side of the afore-mentioned security doors, armoured dolors and the like, intended to operate on the afore-mentioned manipulator head (11) and on the mechanical combination means (12).
The opening/closing assembly (2) comprises an outer shell (20), incorporating an axial pass-through cylindrical seat (21) that houses a rotor (22) coaxial with said manipulator head (11) and the actuator plug (10).
The outer shell (20), solidly and robustly constructed in highly-resistant steel, is integral with said euro profile cylinder (E) and protrudes at least partially outward from the related security door, armoured door, or the like.
The outer shell (20) is ring-shaped and externally formed with decreasing cross-section moving outward from said door, armoured door, or the like, for example tapered as illustrated in the drawings.
The described structure emerges as advantageous since it makes it impossible to fit a pipe or tube in the outer shell (20) used with force to break or eradicate the opening/closing assembly (2).
The rotor (22) is able to slide axially toward the manipulator head (11), in opposition to the spring-loaded components (23) which retain it, when at rest, against a shoulder (24) within the afore-mentioned seat (21).
The shoulder (24) has a lesser diameter than that of the axial cylindrical seat (21) and is situated near the outermost end of the cylindrical seat.
Within the rotor (22), a defender block (25), for impeding external access to the manipulator head (11), is supported rotating, by a pin (25P) with an axis perpendicular to the rotation of the rotor (22).
The defender block (25) is conveniently made of highly-resistant steel, for example in alloy with molybdenum and vanadium, capable of granting the same elevated anti lock-picking and anti-drilling properties.
The defender block (25) is partially accessible externally and close to said manipulator head (11) with the respective internal part, and in the related lateral surface area presents a first profiled face (251) that can be stably paired with a removable flat key (26), and a second profiled face (252), diametrically opposite to the first, which can be provisionally paired with an opening/closing device (27).
In the preferred construction solution as per the drawings, the aforesaid defender block (25) has an essentially spherical shape where at least the first profiled face (251) is flattened and parallel to the rotation axis of the block (25) itself.
In order to obtain a likewise spherical housing, within the rotor (22), it is envisaged that the latter is composed of two parts (22A, 22B), joined to each other by said rotation pin (25P) of the defender block (25) (Dwgs. 3 and 4).
The defender block (25) is envisaged to rotate between at least two characteristic positions, one where the first profiled face (251) is turned outward and can receive the flat key (26).
In the second position of the defender block (25), the first profiled face (251) is turned towards the manipulator head (11) while the second profiled face (252) is turned outward and can receive said opening/closing device (27).
In the first profiled face (251), a male dovetail profile (261) is envisaged, which can engage with a complementary female dovetail profile (262) on the back of the flat key (26) to achieve the stable removable coupling between it and said block (25).
In the second profiled face (252), at least two dead holes (272) are envisaged, parallel to each other and parallel and symmetrically off-centre from the rotation axis of said rotor (22).
The two afore-mentioned dead holes (272) are there to accommodate corresponding plugs (270) protruding from the opening/closing device (27), to accomplish the provisional coupling between it and the defender block (25) (see in particular Dwg. 4).
The flat key (26), illustrated in the drawings from 8 to 11 and adapted for the spherical defender block (25), has an outer face shaped like a spherical cap, with radius equal to that of the block (25), so as to restore the continuity of the spherical shape when they are joined together.
The same spherical cap-shaped outer face of the flat key (26) comprises a number of combination holes (260), of differing lengths, arranged in a circle according to a predefined geometry, for example a circumference, with their axes parallel to each other.
The combination holes (260) are destined to be directed toward the manipulator head (11) and parallel to its axis in concomitance with said second position of the defender block (25), and are suitable for engaging with the corresponding combination pins (120) protruding from the manipulator head (11) to push them along their predefined routes envisaged to release the head, as more fully explained further on.
The lateral surface of the defender block (25) envisages a number of notches (25T), that can be gripped by a fingernail or flat-blade tool, to facilitate the rotation of the block (25) between its two characteristic positions (Dwgs. 1, 2, 12).
In order to more fully define and stabilise the latter, respective centring means (30) have been envisaged, represented in the example by an initial circular cavity (31) made in the centre of the flat key (26) and a second circular cavity (32), identical to the first, made in the centre of the second profiled face (252).
Each cavity (31, 32), in relation to the position adopted by the defender block (25), is alternatively destined to elastically engage with a reference situated in the manipulator head (11), for example the headend of the actuator plug (10), protruding slightly from the latter.
In an initial alternative embodiment, not illustrated, the afore-mentioned defender block (25) has an essentially cylindrical shape whose axis coincides with the rotation axis of the block (25) itself; likewise, at least the first profiled face (251) is flattened and parallel to the rotation axis.
In a second alternative embodiment, also not illustrated, the defender block (25) has an essentially prismatic shape whose longitudinal axis coincides with the rotation axis of the block (25) itself, and where the first and second profiled faces (251, 252) coincide with the corresponding lateral faces of the prism.
Dwgs. 4, 5, 6, 7 illustrate the opening/closing device (27) in the form adapted for the described preferred form for creating the defender block (25).
Conveniently, the opening/closing device (27) can house, within it, the flat key (26) for the transportation of the same, placed in such a way so that the back is presented with the female dovetail profile (262) turned outward.
Therefore, the opening/closing device (27) has a main body (28), shaped to provide an ergonomic grip for the fingers of one hand, which envisages: a compartment (29) for holding, retaining and transporting the flat key (26); a cover (29C) for the closure, at least partial, of said compartment (29); coupling means (271) consisting of a cavity shaped to match the second profiled face (252) of the defender block (25) and at least two parallel plugs (270).
In the example illustrated, the cover (29C) (Dwg. 7) is extractable, but it is possible to envisage a version in which the same is joined via hinge to the main body (28).
In the case in question, the cavity of the coupling means (271) adopts a concave form with a spherical radius equal to that of the defender block (25) and contains, appropriately positioned and protruding outward, the afore-mentioned plugs (270) which, as already mentioned above, can be inserted in the aforesaid dead holes (272) in the second profiled! face (252), so as to accomplish the provisional coupling between said device (27) and the defender block (25).
The sequence of operations necessary for opening the lock (S) by means of the described keyed device (100) is now described, along with the functioning of the latter, already partly intuitable from the previous structural description.
The user observes the defender block (25) to check which of the related profiled faces (251, 252) is turned outward.
In the event that it is not already the first face (251), they take steps to appropriately rotate the defender block (25), possibly with the aid of the notches (25T).
Then, they extract the opening/closing device (27), for example from their pocket or bag, and remove the cover (29C), uncovering the back of the flat key (26).
Using the device (27), they take steps to engage the female dovetail profile (262) of the flat key (26) in the complementary male dovetail profile (261) envisaged in the first profiled face (251).
Disengaging the device (27), the flat key (26) remains stably engaged in the defender block (25), which is subsequently rotated, again with the possible aid of the notches (25T), in its afore-mentioned second position, in which the same flat key (26) is drawn inside, in front of the manipulator head (11).
The slight click by means of which the actuator plug (10) engages in the cavity (31) at the centre of the flat key (26), signals the achievement of the correct position.
Griping the device (27), the plugs (270) engage in the dead holes (272) of the second profiled face (252), until the concave cavity joins the spherical defender block (25).
At this point, acting with suitable manual action on the opening/closing device (27), the following is implemented in order:

the axial translation of the rotor (22) - defender block (25) - flat key (26) assembly, achieving the reaction of the spring-loaded components (23) and with a corresponding sliding of the actuator plug (10), in opposition to the reaction of the respective spring-loaded components (13); the combination holes (260) of the flat key (26) are thus made to couple with the corresponding combination pins (120) protruding from the manipulator head (11), and to push them along their predefined routes envisaged to release the rotation of the latter; the release is achieved when the diametral plane, on which the adjoining first and second parts (121, 122) of each combination pin (120) meet, is flush with the end of the compartment (14), thus all the second parts (122) of the pins (120) are completely inserted in the related holes (16) and emerge as flush with the end of said compartment (14); in this condition, the rotation of the manipulator head (11) is permitted, which causes the angular separation of all the first parts (121) from the respective second parts (122) of the combination pins (120), which remain inside the holes (16) in the flange (15);
the rotation, in the appropriate direction, of the rotor (22) - defender block (25) - flat key (26) - manipulator head (11) and actuator plug (10) assembly, with consequent rotation in the same direction of said cam (C) to open the lock (S).
the release of the pressure on the device (27) and the disengagement of the later from the defender block (25);
the opening of the door or hatch or the like;
the rotation of the defender block (25) and the extraction of the flat key (26).

Obviously, the closure of the lock (S) is performed by means of a similar procedure, which has not been described.
All the innovative aspects of the keyed device proposed emerge from the above, radically changing the construction concept adopted to-date.
The most important of these aspects involves having removed - from the key - the function of mechanical connection device which receives the manual act directly and transmits the opening and closing action of the look to the mechanism, delegating it to the opening/closing device which also acts as container and protection for said key when not in use.
Another advantage derives from having made the area in which the flat key of the device presents its cuts to the mechanical combination means inaccessible from outside, as well as well protected from attacks of elevated force.
The construction-related aspect just mentioned also prevents any action aimed at the reverse detection of the correct combination cut of the key, with a considerable increase in security.
The construction-related attention dedicated to the "passive" protection of the lock is of particular significance, envisaging the parts subject to attack as generously sized and made of highly-resistant steel, neutralising lock-picking attempts using devices such as drills, cutting disks or the like, or at least making them very difficult.
The structure of the keyed device described makes it possible to combine it with additional accessory devices, both mechanical and electromechanical, aimed at further increasing the security of the same.
It is therefore understood that the aspects described are by way of example but not limited to, therefore any detail changes which might become necessary for technical and/or functional reasons, are considered to fall from this point on within the same protective sphere defined by the claims made below.

Keyed device according to any one of the preceding claims, characterised by the fact that the flat key (26) and the second profiled face (252) both have centring means (30), identical to each other, that can alternately elastically engage with a reference situated in the manipulator head (11), to define and stabilise the two characteristic positions of the defender block (25).
Keyed device according to any one of the preceding claims, characterised by the fact that the main body (28) of the locking/unlocking tool (27) has a compartment (29) for holding, retaining and transporting the flat key (26), and a cover (29C) for at least partially closing the compartment (29).
Flat key (26) for use with a keyed device (100) for operating locks (S) according to any one of the claims 1 to 10, characterized by the fact that it comprises: a number of combination notes (260), of differing lengths, arranged in a circle according to a predefined geometry, with their axes parallel to each other, and which can be directed toward the manipulator head (11) and parallel to its axis, in concomitance with the second position of the defender block (25), where the combination holes (260) can couple with the corresponding combination pins (120) projecting from the manipulator head (11) to push them along the predefined distances for releasing the head; a female dovetail profile (262), along the back of the flat key (26), can couple with a complementary male dovetail profile (261), in the defender block (25) to establish a stable and removable coupling between them.
Locking/untocking tool (27) for use with a keyed device (100) for operating locks (S) according to any one of the claims 1 to 10, characterised by the fact that it has a main body (28), shaped to provide an ergonomic grip for the fingers of one hand and comprising: a compartment (29) for holding, retaining and transporting the flat key (26); coupling means (271) consisting of a cavity shaped to match the second profiled face (252) of the defender block (25) and at least two parallel plugs (270), that project outward and can be inserted into corresponding dead holes (272) in the second profiled face (252), for achieving the provisional coupling between the tool (27) and the block (25).
