Definitions

  • the subject of the present invention is a cylinder lock, of the type comprising a lock body or stator, a cylinder or rotor, mounted so that it can turn in the body and having a passage for introduction of a key, and an aligned series of first pins mounted so that they can slide radially in the cylinder in positions distributed along the axis of the cylinder, and an aligned series of second pins, mounted so that they can slide radially in the stator and designed to co-operate with said first pins.
  • the present invention refers to a cylinder lock of the rekeyable type, which can be operated with different keys, following upon rekeying operations.
  • Cylinder locks of this type are by now extremely widespread and extensively used in the building sector, for providing, for example, during work-site operations, in which a complex of dwellings is being built, the possibility of using a single site key common to all the locks associated to each of the various dwellings, and, at the moment when the latter are handed over to the owners, the possibility of rekeying the locks with purposely provided means in such a way that each lock will be operated only using a specific owner's key.
  • Cylinder locks of a rekeyable type according to the known art have a very complex structure that requires extremely elaborate rekeying operations, so that providing locks of a rekeyable type according to the known art in sets of the type referred to above characterized by a large number proves extremely complicated and difficult to achieve.
  • a cylinder lock of the rekeyable type according to the preamble of claim 1 is for example known from documents WO 2007/007313 A1 or CH 652 164 A5 .
  • the purpose of the present invention is to provide a cylinder lock of a rekeyable type having a very simple structure that envisages rekeying means provided for offering ample possibilities of variation of the lock combination, so as to enable a user to obtain sets of locks of the type described above that, as will be illustrated in what follows, are suited to a wide range of settings of operation.
  • a cylinder lock of the type described in the preamble of Claim 1 comprises: a rekeying element, which is set in a position corresponding to the interface between the rotor and the stator, in a first position within said cylinder or rotor said rekeying element preventing two or more of said first pins from co-operating with respective second pins for determining the combination of the lock, said second pins being blocked by the rekeying element outside of the rotor; said lock being such that into said key passage a main key can be inserted that co-operates with said two or more first pins so as to displace said rekeying element into a second position such that, following upon rotation of the rotor, said rekeying element sets itself within a seat made in said rotor so as not to be able to interact any longer with said two or more first pins.
  • the rekeying element according to the present invention is provided for co-operating with a plurality of first pins of the stator so that, in an extremely simple way and with a far from complicated structure, it is possible to intervene on a number of rekeying characteristics of the lock. Furthermore, deactivation of the rekeying element, and hence rekeying of the lock, is obtained in a simple and fast way via the use of a main key specific for each lock.
  • a system of cylinder lock and key according to claim 13 is furthermore provided.
  • the lock 1 comprises a body 8 or stator traversed by a cylindrical passage 9, within which a rotor or cylinder 10 is mounted so that it can turn.
  • a series of first pins 11 mounted slidably and radially within respective radial holes 10a made in the cylinder 10 giving out into the passage 12 made axially through the cylinder 10, for introduction of a key.
  • the first pins 11 co-operate with second pins 13, mounted so that they can slide radially in respective holes 8a, which are made in an area corresponding to a flange extension 8b of the stator body 8, and recalled by springs 14 against the first pins 11.
  • a rekeying element 2 is set in an area corresponding to the interface between the cylinder 10 and the stator body 8, set between the first and second pins 11, 13.
  • the rekeying element 2 is formed by a bar that extends in an area corresponding to the interface between the cylinder 10 and stator 8, in a direction parallel to the axis of rotation of the cylinder 10.
  • a notch 4 is provided, extending parallel to the axial direction of the cylinder by at least a stretch equal to the length of the bar 2.
  • the notch 4 extends throughout the length of the cylinder 10.
  • the notch 4 develops also in depth in a radial direction of the cylinder 10.
  • the bar 2 can then set itself in the cylinder 10 so as to traverse a number of radial holes 10a and consequently intercept the respective first pins 11 provided therein.
  • a corresponding notch 5 is further envisaged in the stator body 8 (visible in Figure 8 ) in a position corresponding to the cylindrical passage 9 where the holes 8a within which the second pins 13 slide are made.
  • the notch 5 extends parallel to the axial direction of the cylindrical passage 9 for a stretch equal at least to the length of the bar 2.
  • the notch 5 extends throughout the length of the cylindrical passage 9.
  • the notch 5 develops also in depth in a direction substantially parallel to the direction of translation of the second pins 13.
  • the bar 2 can then be translated between the cylinder 10 and the stator 8 in a direction substantially parallel to the direction of sliding of the second pins 13.
  • the bottom surfaces of the notches 4 and 5 define end positions of the bar 2 within the cylinder 10 and the stator 8, respectively.
  • the notch 4 has a depth equal to the thickness, in the radial direction of the rotor, of the bar 2, in such a way that the bar 2 bearing upon the bottom of the notch 4 is substantially flush, at its opposite side facing the outside of the rotor, with the cylindrical surface of the latter.
  • the bar 2 blocked in said end position prevents the first pins 11 intercepted thereby from acting through the second pins 13 for determining the combination of the lock.
  • the first pins 11 do not co-operate with the respective second pins 13, which are blocked by the bar 2 outside of the rotor 10 so that the latter is free to rotate independently of the "keying" (i.e., the conformation of the key body) that a key inserted presents in the area corresponding to said first pins 11.
  • the first pins 11 on which the bar 2 acts are "de-activated".
  • the rekeying element 2 it is thus possible to "de-activate" a plurality of first pins 11 of the rotor 10 in such a way as to modify the combination of the lock.
  • the combination varies in the sense that a smaller number of pins, with respect to the total number of pins available, is active for determining the effective combination of the lock.
  • first pins 11 with the same keying characteristics, understood as height and position of the pins, so that by "de-activating", via the bar 2, the further first different pins 11, the aforesaid first pins 11 provide in each lock one and the same combination associated to the aforesaid site key.
  • the bar 2 is provided for acting on three first pins 11 of the cylinder 10 ( Figure 5 ).
  • the bar 2 can, however, have a length such as to act on the number of first pins 11 desired for the various applications.
  • cylinder locks With the cylinder locks according to the present invention, it is moreover possible to provide a set of locks, which, in an initial stage of use, provides a first common key, and, in a subsequent stage of use, is differentiated into sub-set of locks each provided with a respective second key, common to the locks of the same sub-set. In a final stage of use, the locks of each sub-set can be differentiated from one another by being provided with a specific keying configuration. In this particular arrangement of a set of locks, it is possible to provide a number of rekeying elements 2, which are removed (with the modalities described in what follows) in subsequent stages of use of the locks.
  • the various sub-sets of locks are defined, each formed by the locks with the "activated" pins that have the same keying characteristics.
  • the locks of different sub-sets are differentiated from one another as regards the various keying characteristics of said "activated” pins.
  • the locks of the same sub-set can be activated via the second common key thanks to the presence of the further rekeying element that acts on the remaining "de-activated” pins.
  • the cylinder locks according to the invention are consequently extremely flexible and suited for generating sets and sub-sets of cylinder locks with a worksite key and owner's keys, in the number and with the modalities required in the individual cases.
  • the locks according to the invention are extremely flexible and can be easily adapted to the requirements of use.
  • each lock so as to be prearranged for a given set and sub-set is extremely simple and easy to study at the design level, in so far as the bar, which constitutes the rekeying means according to the invention, enables a wide range of possibilities of setting since it is possible to choose selectively and vary according to the cases its length, and hence the number of rekeying elements (the first pins 11) on which it acts, the position, the number, and, in the case where a number of bars is envisaged, the number of steps for de-activation of said bars.
  • the cylinder 10 has a housing seat 6 at a radial end that is rotated through a certain angle with respect to the radial holes 10a of the cylinder 10.
  • the housing seat 6 extends in a direction substantially parallel to the axis of rotation of the cylinder 10.
  • the housing seat 6 extends throughout the length of the cylinder 10.
  • Figures 1 and 5 illustrate a condition where a site key 3a is inserted within the key passage 12.
  • the body of the site key has, at its longitudinal section designed to co-operate with the pin 11 "de-activated" via the bar 2, a cross section of dimensions such that the pin 11 and the bar 2 lie within the cylinder 10.
  • the notch 4 provided in the cylinder 10 has a depth equal to the radial thickness of the bar 2, in such a way that the second pin 13 that acts against the bar 2 remains on the borderline between the stator body 8 and the rotor 10, on the outside of the latter, the cylinder 10 consequently being free to rotate.
  • the body of the site key has a cross section co-operating with the first "de-activated" pins 11 of maximum dimension such that, also in the cylinder lock of the set of locks that has first pins 11 "de-activated” of greatest longitudinal extension, said pins and the bar 2 lie within the cylinder 10.
  • the site key has a key body with the aforesaid maximum dimension in an area corresponding to the entire portion thereof co-operating with the "de-activated" pins 11.
  • Figures 2 and 6 represent a condition where the owner's key 3b of the lock shown in said figures is inserted within the key passage 12.
  • the owner's key has keying characteristics, which, in combination with the keying characteristics of the first pin 11, provide a configuration such that the cylinder 10 is free to rotate.
  • the first pin 11 is in fact carried by the aforesaid specific key within the cylinder 10 flush with the external surface of the latter, as generally occurs during activation of conventional locks.
  • the displacement of the pin 11 brought about by the owner's key entails a translation of the bar 2 within the housing notch 5 provided in the stator body 8.
  • the present invention provides a cylinder lock of the rekeyable type characterized by a high simplicity of construction and use, in which rekeying of the cylinder lock is moreover carried out in a simple and fast way using a main specific key.
