Definitions

  • the invention falls within the technical sector of high-security locks according to claim 1.
  • keyless mechanical locks for example featuring combination dials such as those on safes
  • 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 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.
  • the key represents both an opening device and a protection system; if one manages to bypass the latter, the lock is violated.
  • 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.
  • 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:
  • 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).
  • the device (100) includes a (1) mechanism for operating said cam (C), in which the following is envisaged:
  • 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).
  • each of 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).
  • 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 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.
  • 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).
  • 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.
  • 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).
  • 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).
  • 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).
  • 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).
  • 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.
  • 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.
  • 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).
  • 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.
  • 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).
  • 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).
  • 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 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 plugs (270) engage in the dead holes (272) of the second profiled face (252), until the concave cavity joins the spherical defender block (25).
  • 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 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.
