Definitions

  • the present invention relates to a cylinder lock with an interchangeable key, comprising: a stator with a cavity for a cylinder, at least one longitudinal groove formed in said cavity, and a series of seats opening in the cavity of the stator; a cylinder comprising a key slot, seats cutting said key slot, as well as a first slot and a second slot, orthogonal to said seats and parallel to the axis of the cylinder; a series of slides inserted with longitudinal and transverse mobility in the seats of said cylinder to cooperate with the notches of a key inserted in said key slot, each slide being provided, on one side, with projections; a series of studs slidably mounted in the seats of said cylinder and able to cooperate with parts of the stator, said studs being provided with a series of first notches turned towards the projections of said sliders, and at least one second notch, turned towards the side opposite to said slides; a stop bar, inserted in said first orthogonal slot of the cylinder, provided with projections turned towards
  • Such a cylinder lock with an interchangeable key is known from US-A 3,999,413.
  • this lock does not have the operational security which is required of a quality lock.
  • the studs can move laterally with the sliders during the change of the key, and when this occurs it is no longer possible to correctly code the lock with a new key.
  • the sliders can remain engaged with the studs, or else be in an inclined position, when the translation bar is moving, thus preventing a new codification of the lock.
  • such a lock cannot be produced in the forms, sometimes preferred, comprising counter-studs.
  • the key must be of a special type having complementary notches on both sides, so that this key is expensive, requires special equipment for its production, and includes the possibility of a relatively small number of codifications.
  • the main object of the present invention is to provide a cylinder lock of the indicated type, in which the reported drawbacks, or at least some of them, are systematically avoided.
  • a particular object of the invention is to produce such a lock allowing a greater number of codifications.
  • Another object of the invention is also to make it possible to subject several cylinder locks to one and the same opening key, as well as to allow easy replacement. normal industrial production cylinder locks by interchangeable key locks.
  • a cylinder lock of the indicated type characterized in that the cylinder comprises, in addition to the series of first seats, in which said slides are inserted, a separate series of second seats, parallel to the first seats, in which said studs are inserted; that each slide is provided with an associated spring and, on the side opposite to the projections, with a sliding coupling element; that the stop bar is associated with springs which push it outwards; and that the translation bar associated with springs which push it outwards and comprises sliding coupling elements capable of engaging with the sliding coupling elements of said sliders.
  • the characteristics of the object of the invention are compatible with the requirements of a rational and mechanized assembly of the lock, and they assure the user the greatest ease of execution of the operations relating to the recodification of the lock, that is to say the change of its key. It is therefore easy to subject several locks to a single key.
  • the lock according to the invention can be produced with a space corresponding to that of a usual lock, thus making it easy to replace existing locks.
  • the cylinder lock with interchangeable key is formed by a stator 1 provided with a cavity 2 in which is installed in a rotary manner a rotor formed by a cylinder 8 and by a head. 9.
  • a stator 1 provided with a cavity 2 in which is installed in a rotary manner a rotor formed by a cylinder 8 and by a head.
  • In the wall of the cavity 2 of the stator 1 is hollowed out at least one longitudinal stop groove 3.
  • Each bolt 5 has a portion of concave cylindrical surface 5 ', which, in a position fixed with the bolt 5, corresponds to the skirt surface of the cylinder 8 ( and therefore allows free rotation).
  • the studs can all be identical to each other.
  • the shape and external dimensions of the stator of the lock according to the invention can be identical to those of common cylinder locks, so as to allow easy replacement of a common lock with
  • a longitudinal slot 10 for the introduction of a key is formed in the cylinder 8 and in the head 9 of the latter.
  • the slot 10 is shown with flat and parallel walls, but it is understood that it can have any of the profiles provided for the keys.
  • the cylinder 8 is provided, at its rear end, with a transverse cavity 11 by means of which it can be connected to any known mechanism, intended to be actuated by the lock, for example a retraction mechanism which can be actuated by rotating the cylinder 8 by means of an appropriate key inserted in the slot 10.
  • the cylinder 8 is provided with two diametrically opposite lateral slots, 12 and 13, parallel to the axis of the cylinder 8 and perpendicular to the key slot 10, which are intended to receive, respectively, a stop bar and a bar translation.
  • the cylinders 8 are formed seats 13 and 15, orthogonal to the axis of the cylinder 8 and to the slots 12 and 13; the seats 14 cut the key slot 10 and are intended to receive sliders cooperating with the notches of the key, while the seats 15 are intended to receive studs which cooperate with said slides, with the studs 5 installed in the stator of the lock and with the stop bar. Walls partially separate said slots and seats formed in the cylinder 8.
  • a cover 6 is provided for closing the ends of the seats 14 formed in the cylinder 8.
  • each seat 15 of the cylinder 8 is inserted a stud 17 corresponding to one of the studs 5 of the stator 1.
  • Each stud 17 has a portion of convex cylindrical surface 17 ', complementary to the concave surface 5' of the stud 5, and it has on its outer surface a number of shallow notches 18 and a deeper notch 19, and on its inner face a similar number of notches 20.
  • the notches 18-20 may for example be conical, in the form of a dihedral or a rack, or d 'a similar configuration.
  • the deeper notch 19 is located in a position such that it appears in correspondence with the slot 12 of the cylinder 8 when the surface 17 ′ corresponds to the surface of the outer surface of the cylinder 8, and it is the only notch of the series 18-19 which has an operative function; the other notches 18 have a simulation function to obstruct actions tending to decipher the code of the lock.
  • notches 18 of reduced depth are sufficient for the simulation effect, for reasons of constructive expediency the notches 18 can also be made with the same depth of the notch 19.
  • the studs 17 can all be identical to each other.
  • each seat 14 of the cylinder 8 is inserted a slide 21, a side of which has one or more protrusions 22, for example conical or chisel point or rack, suitable for engaging with the notches 20 of the studs 17, while that the opposite flank has a groove 23 with sliding coupling, for example in the form of a dovetail.
  • Each slide 21 is slidably mounted in the corresponding seat 14 and it is pushed outwards by a spring 24 which bears on the cover 16; in addition, each slide 21 is mounted in the seat 14 with a certain clearance, so as to be able to move transversely between two positions, in one of which its projections 22 are engaged with the notches 20 of the corresponding stud 17, while in the other position the projections 22 are disengaged.
  • the slides 21 can all be identical between them.
  • a stop bar 25 having, for each stud 17, one or more projections 26, for example conical or chisel point, suitable for engaging in the notches 18 or 19 of the studs 17.
  • This engagement is made possible by holes 12 'hollowed out in the wall which separates the slot 12 from the seats 15.
  • the stop bar On the side opposite to the projections 26, the stop bar has a stop projection 27 suitable for entering the groove stator stop 1.
  • the stop bar 25 has seats 28 for springs (not shown) intended to push it elastically outward in the slot 12 which receives the stop bar.
  • the seats 28 for the springs can also be hollowed out in the cylinder 8 instead of in the stop bar 25.
  • a translation bar 29 having, on the outside, a similar projection 30 of the stop projection 27 of the stop bar 25, and, on the inside, sliding coupling projections 31, in number equal to the number of slides 21.
  • the projections 31 can be, for example, in the shape of a dovetail (as shown), or else with an enlarged circular end edge, and they are intended to engage in the sliding coupling grooves 3 of the slides 21, which are configured in a complementary manner.
  • This engagement is made possible by slots 13 ′ formed in the wall which forms the separation between the slot 13 and the seats 14 of the cylinder 8, through which slots the protrusions with sliding coupling 31 protrude into the seats 14.
  • the translation bar 29 has seats 32 for springs (not shown) intended to push it elastically outwards in the slot 13 which receives the translation bar.
  • the seats 32 for the springs can also be hollowed out in the cylinder 8 instead of in the translation bar 29.
  • the holes 12 'and the slots 13' have less weakening of the cylinder 8, and therefore they are to be expected when the cylinder is made of a metal of low resistance.
  • the cylinder 8 is made of a metal of high resistance, such as for example stainless steel, the holes 12 'and the slots 13' can be replaced by more extensive millings 13 ", as is has shown, for one of them, by broken lines, in FIGS. 10 to 12. This allows the machining of cylinder 8 to be exemplified.
  • the lock is finally completed by inserting into the stator 1 the studs 5, the springs 6 and the plugs 7 relating thereto.
  • these operations can be carried out easily even by mechanical means, especially because they do not require any choice of parts corresponding to a codification of the lock, as long as the studs are all equal to one of the other, and so are the studs and slides.
  • the lock thus prepared is in no way codified, and it can be actuated by a neutral key or by any instrument inserted in the key slot 10 without moving the sliders 21.
  • the lock will be coded successively, as is will explain later, in the meantime it can be stored without any reference to corresponding keys, so with a subsequent advantage of organization and economy.
  • the lock will be installed and, if desired, it can still be used with a neutral key; this procedure allows, among other things, the use of a single neutral key for all the locks of a building being finished. Only when the user takes possession of the premises, the lock must be coded by a key chosen by the user, which key was not previously in the possession of any other person, and which, if desired, can be equal for all the locks being part of the same relevance.
  • FIG. 2 a section of the lock, coded in any way and in the condition of rest, that is to say that the key is taken from the slot 10.
  • the bolts 5 of the stator 1 pushed by the springs 6, partially penetrate the seats 15 of the cylinder 8, blocking the latter.
  • the stop bar 25 does not block the studs 17 because it, pushed by its springs, penetrates by its projection 27 in the longitudinal groove 3 of the stator, thus disengaging the projections 26 from the holes 19 of the studs 17; the latter are raised by the action of the slides 21, engaged with them by means of the projections 22 and the notches 20, and pushed by the springs 24.
  • the cylinder 8 cannot rotate; the lock is blocked.
  • the translation bar 29 finds the groove 3 of the stator opposite its own projection 30 and, pushed by its springs, it moves outwards. By this movement it also causes the slides 21 to move transversely, since their sliding coupling elements 23 are engaged with the sliding coupling elements 31 of the translation bar 30. Consequently, the projections 22 of the slides 21 are released from the notches 20 of the studs 17 which, moreover, are held stationary by the action of the stop bar 25.
  • the position described above constitutes a position authorizing the change of the key. Indeed, the slides 21 which, being released from the studs 17, have resumed their mobility, no longer retain the key K, which therefore can be extracted ( Figure 6). The sliders 21 are then pushed all at the end of their travel by the springs 24 and, if at this point the cylinder was still turned without a key, the lock would return to an uncoded condition, and it could then be actuated at using a neutral key. If, on the other hand, a new key K 'is inserted into the slot 10 (FIG. 7), the slides 21 are arranged in a new position corresponding to the series of notches of the new key K'.
  • the key change positions can one or more. In special cases, it is also possible to coincide with the key change position with the lock open position.
  • sliding coupling elements have been indicated in the form of studs 31 arranged on the translation bar 29 and of mortise grooves 23 provided on the slides 21, it is understood that this arrangement can be reversed.
  • the sliding couplings indicated as being made in the form of a dovetail, could on the other hand be in the shape of a T or with any other suitable profile.
  • the invention can find its application either to locks for the doors of buildings and the like, or also to locks for safes, armored cabinets, and so on.
  • the invention has been described in relation to a lock in which the seats 4 of the stator extend on one side and have relative studs and springs, but it should be understood that it can also be applied to locks in which the seats 4 of the stator extend on both sides relative to the cavity 2 of the stator and, in this case, they may possibly be devoid, on one or both sides, of studs and springs relating thereto; the seats 15 of the cylinder are then piercing and the studs 17 inserted in these seats must conform, at their two ends, to the profile of the cylinder in the open and change position of the key.
  • the stator 1 has, in this case, a thickness cor corresponding to the stroke of the 17 "studs, and it can be substantially cylindrical.
  • the 17" studs are limited at both ends by surfaces which, in the open position of the lock (shown in FIG. 28), correspond to the outer surface of the cylinder.
  • the stator 4 "seats extend on both sides of the cylinder, and they have no studs and springs.
  • the components included in the cylinder in addition to the 17" studs are identical to those already described, and also identical is their operation.
  • FIG. 28 also shows a ball 33 with a pressure spring 34 retained by a cover 35. These parts are inserted in the stator 1 "in the position to which the internal end of the key K corresponds when the lock is in the change position of the key (see also Figure 9) The ball 33 engages with the cylinder preventing its rotation if the key K is not fully inserted in its seat, thus preventing any possibility of faulty coding.
  • a similar arrangement of ball with spring can be provided at 36 (figure 9) to prevent the extraction of the key, in the change position, if the key has a notch corresponding to ball 36.
  • This allows prediction keys that do not allow the change operation to be performed. This operation can be carried out, in this case, only by the use of keys devoid of said notch, which will be consigned only to authorized persons.
