TEXT OF THE DESCRIPTION

The device with coded rings and spheres with retractable freedom of movement, was born from a previous â € œsupport with ballsâ €, still in the state of an unpublished application, of an industrial patent (NA2009A000073), which the same owner filed on 01 / 12/2009 at the UIBM of Naples.

In summary, the aforementioned application NA2009A000073 exposes a â € œsupport with ballsâ € for the realization of locks, where the balls in question are housed in rings with a fixed position without the possibility of being able to translate along a radial direction of the rings themselves. This constraint condition circumscribes the industrial use of the â € œball locksâ € to the creation of locks with a single key entry, with an optional defined rotation (right or left) and within the limit of one revolution of the locking Cam. In other words, with the device already deposited it is possible to produce locks only for specific uses, for example: safes, alarms, car doors, etc., where it is particularly required to open the window from one side only with one rotation right or left of the Key.

Said â € œsupport with ballsâ € deposited in Italy, it has already undergone the EPO evaluation, and has been recognized as valid as an industrial invention applicable in the field of locks, as its characteristics are neither known nor made obvious by the previous one â € œavailable artâ € (written opinion by the examiner).

Furthermore, again with regard to the current application (NA2009A000073), in the â € œReport of

Researchâ € patents from the last century have been mentioned, of locks containing balls inside that simply have the task of pushing on Yale-type pistons: these balls do not perform any active function in determining, with the rotation of the key, the secret combination of the door lock.

In fact â € œ the state of the previous art â € has no correspondence with the mechanism of the deposited invention, where the innovation consists of the union of coded rings and spheres with a particular cylindrical key which carries on the cylindrical circumference, a series of curved and concentric channels, programmed at various angles: the rotation of the key progressively engages the spheres of the rings in different positions, which by turning different angles determine the secret coding of the lock.

The new device with coded rings containing â € œa retractableâ € spheres, referred to in the title of the present invention and subject of the current patent application, allows the creation of locks having a rotating body with bidirectional motion, that is with the possibility of operating the closing with one or more turns, both with a right rotation of the key and at the same time also left.

Furthermore, with this device with â € œa retractableâ € spheres, it is possible to create doors and windows with key entry only on one side (single entry locks) and also on two sides (double entry locks).

The Drawing Tables from 1/5 to 5/5 are attached to the Description of the new encoded ring device containing â € œa disappearingâ € spheres:

Functional description of the New Device with Rings and Spheres â € œa retractableâ €

The `` retractable '' Ring and Sphere Device previously illustrated in its constructive parts (see the Drawing Tables), appears as a complex mechanical device, where the Device coupled with a particular cylindrical key makes the assembly specifically suitable for the creation of security locks.

The description takes as a model a lock of the bidirectional type, widely used on the market and particularly used in armored doors, with a new Ball Device inside (Plate 1/5 - Fig. La), where the aforementioned spheres, pushed from the Key, they can disappear into Chambers (2a) made on the rotating Body (2).

Note that the rotating body (2) cannot rotate because it is stopped by the blocking balls (11) which contrast in the channel (lb) of the fixed body (1).

The Device is therefore composed of a series of encoded rings (9): their quantity determines the number of encodings (ciphers). In the type of lock taken as an example in this description there are five coded rings.

It is possible to create locks with a different number of rings coded according to the many and various applications required by the market. Each Ring (Tab. 3/5) has its own distinctive code (01, 02, 03, ..etc). The codes are not detectable with probes inserted in the key entry hole (tamper-proof peculiarity), because the coding is carried out on the invisible part of the Rings. The coded rings are activated by a key, new of its kind, not existing on the market and manufactured only with special tools and machines built for the purpose. The Key (Fig. 3) and a variant of it (Fig. 4) are shown in Table 1/5. In Table 2/5, Fig. 5 shows a non-coded key: note the grooves (5a) which, when the key is inserted into the lock, will engage the device spheres (5) present in the coded rings.

The two grooves (5a), with their shape, also have the function of making the key enter the lock by sliding along the device spheres (5) present in the rings described above. Also in Table 2/5 - Fig.6a the channels (6a) are shown which are mirrored with respect to the central axis; also the other channels, in the different positions (1, 2, 3, 4, 5) are mirrored with respect to the central axis of the key: the different angular lengths define the coding of the key.

The channels made on the key are concentric with lengths of arches having different angles (xl, x2, x3 etc ..), complementary to the angles (yl, y2, y3 etc ..) of the Cavities (c) present on the Coded Rings; when the aforementioned Cavities (c), due to the effect of the combinatorial action of the Key, are all aligned, the Blocking Spheres (11) will be able to release from the Channel (lb) of the fixed Body (1); at this point the rotating body (2) and the cam (4) connected to it, together will be able to rotate allowing the opening.

In other words, simplifying, after having completely inserted the Key into the Lock,. turning it will engage the Rings in a progressive and casual way, according to the codification present on the Key itself; the Rings will each rotate by its own angle in order to align the Cavities (c). This allows the locking balls (11) to be released from the fixed body (1) thus allowing the rotating body (2) and the cam (4) to rotate as well and thus allow the lock to open.

The Keys can be â € œspecularâ € (Fig. 6), or â € œnot specularâ € (Fig. 7); this feature leads to a significant increase in possible encryption.

The Keys can be further differentiated with some significant variants (v) of special keys as shown in Fig. 4 -Tav. 1/5.

Before analyzing Table 5/5, which shows the kinematics of the new device with coded rings and â € œa disappearingâ € spheres, for preparatory purposes, it is necessary to examine the task of some mechanical parts functional to the device.

In Table 4/5 we have: the separator ring (Fig. 14). which carries out the task of keeping the different coded rings separated and braked in the initial position (note the ears (14a) constrained in the chambers (2a) of the rotating body) and the positioning and braking bosses (14b) of the rings; the control ring (Fig. 15) with two spheres (5) and the control ring (Fig. 16) with a single sphere (note that both rings have grooves (g) and cavities (c) ; the Cap (Fig. 17) which performs the task of closing the device (note the â € œpâ € profile which allows only keys with the same shape to enter); the Rotating body (2) with the Chambers (2a ) where the spheres will go in. Table 5/5 shows the operation of the device with coded rings and â € œa retractableâ € spheres, particularly aimed at making safety locks.

It should be noted that with this device, once the right key has been inserted, it is possible to open or close the lock by turning the key to the right or to the left, even by making several turns (in the case of locks for multiple-throw doors).

Also in Table 5/5 some typical sequences of the new kinematics are shown with the following sections taken as reference: Section AA of the Key (Table 2/5-Fig. 6), Section AA of Ring code 01 ( Tab.3 / 5-Fig.8), Section CC of the single ball control ring (Tab.4 / 5-Fig.l6); observe the rotation sequence of the key with the beginning of the corner

A = zero (Fig. 18): note the subsequent movements of the key with the angles Al, A2, A3 which characterize some phases of the lock opening cycle (Figs. 18a, 18b, 18c). In this opening cycle, the key turns clockwise (right); however, as already mentioned above, the device is bidirectional, so depending on the type of lock, it is possible to have opening cycles with the key turning counterclockwise

(left); again in Table 5/5, Fig. 19 shows a simplified section of the kinematics for demonstration purposes (Sect. DD-Table 1/5): note the rotating body (2) bound by the locking sphere (11) to the fixed body (1) which for simplicity is shown cylindrical; The Ring (9) coded 01 (Fig.8-Tab.3 / 5); the Spheres (5sx) and (5dx); the Sphere (11); in the central part the key is shown, as seen in Fig. 18 with angle A = zero. Figures 19a, 19b, 19c show some significant phases of the lock opening cycle: observe that by turning the key at an angle of â € œAlâ € (Fig.18a), the Groove (6s - dx) initially engages the Sphere (5 right) ) thus forcing the ring (9) coded 01 to rotate (Figs. 19, 19a); at the end of the â € œAlâ € corner phase, the Key pushed the Sphere (5 right) into the Chamber (2a - right) of the rotating body (2); at the same time the Key, with the Canal (6a - left) engaged the Sphere (5sx). Detect the fact that the Sphere (5dx) has `` disappeared '' from the socket of the key: the Key can now push the coded Ring to rotate from the `` A2 '' angle (Fig.l8b) until it reaches the Cavity ( c - dx) in the release position of the locking ball (11); a further rotation increase (angle â € œA3â € - Fig. 18c) and the lock is open. Note (Fig. 19c) how the locking Sphere (11) has re-entered the Cavity (c - right) of the coded Ring: therefore the rotating body (2) no longer constrained can turn and operate the Cam (4) (with one or more turns) for the lock opening command.

Simultaneously, the phases of the other coded rings take place: the rings rotate with different angles, correlated to the different angular lengths (arcs) of the coded channels 6a, 6b, 6c, 6d, 6e of the key (Fig. 6 - Table 2 / 5); simplifying: when all the cavities (c) of the rings are aligned, the locking balls (11) can free themselves from the channel (lb) of the fixed body (1); finally, the rotating body (2) can turn together with the key, activate the Cam and open the lock. Note in Fig.20, the Control Ring (8a) in its initial position, before the opening cycle. Turning the key pushes the Sphere (5) and the Cavity (c) to engage (Figs. 20a, 20b) the locking Sphere (11); a further rotation of the key releases the sphere (11) from the channel (lb) of the fixed body (1) forcing the rotating body (2) to turn together with the key with the consequent opening of the lock. By turning the key in the opposite direction, the closing phases of the lock take place (Figures shown on the right of Table 5/5).
