    [0010] The use of lock systems comprising a key and a lock cylinder is known.
    [0011]
    [0012] Such a lock system comprises a key with a key blade having a plurality of code surfaces arranged one after the other in the longitudinal direction of the key blade, and which is inserted into a key housing existing in a lock cylinder. The lock cylinder comprises a stator and a rotor that rotates inside the stator, the cylinder being provided with a plurality of housings, so that in each of these housings a rotor pin and a stator pin moveable in the radial direction of the lock cylinder, so that when the blade of a valid key is completely inserted into the lock cylinder, said rotor and stator pins are positioned in code, enabling rotation of the rotor, which causes the opening of the lock.
    [0013]
    [0014] EP2360334B1 describes a lock system where the lock cylinder comprises a validation element that at least partially extends into the key channel, and where the key comprises a control recess configured to correspond to the lock element in such a way that the locking element is housed in the recess when the key is inserted into the key channel. In the lock system described in EP2360334B1, the recess is longer than the length along which the locking element is inserted into the recess.
    [0015] STATEMENT OF THE INVENTION
    [0016]
    [0017] The object of the invention is to provide a lock system, as defined in the claims.
    [0018]
    [0019] The lock system of the invention comprises a lock key comprising a key blade, a control recess on at least one of the faces of the key blade, and a plurality of code surfaces arranged one following the another in the longitudinal direction of the key blade.
    [0020]
    [0021] The lock system of the invention further comprises a lock cylinder. Said lock cylinder comprises a stator and a rotor configured to rotate in a hole in the stator, the rotor comprising a key housing configured to receive the key.

    [0044] DETAILED EXHIBITION OF THE INVENTION
    [0045]
    [0046] Figures 1 to 6 refer to a first embodiment of the lock system 100 according to the invention.
    [0047]
    [0048] The lock system 100 of the invention comprises a lock key 1 comprising a key blade 11. The key blade 11 comprises a front face 115, two major lateral faces 113, 114 and two minor lateral faces 111, 112.
    [0049]
    [0050] The lock key 1 further comprises a control recess 12 on at least one of the faces 111, 112, 113, 114, 115 of the key blade 11, and a plurality of code surfaces 14 arranged one after the other in the longitudinal direction of the key blade 11.
    [0051]
    [0052] The lock system 100 of the invention further comprises a lock cylinder 2. The lock cylinder 2 comprises a stator 21, and a rotor 22. The rotor 22 is configured to rotate in a hole in the stator 21 and comprises a key housing 23 configured to receive the key blade 11. The key housing 23 extends longitudinally along the rotor 22 and comprises an inlet port on the front face 220 of the rotor 22.
    [0053]
    [0054] The lock cylinder 2 further comprises a plurality of housings 24 each housing 24 containing at least one rotor pin 25 and one stator pin 26 movable in the radial direction of the lock cylinder 2, with the rotor pins 25 and the surfaces of code 14 configured to cooperate with each other when key 1 has been fully inserted into lock cylinder 2. Rotor pins 25 and stator pins 26 are pushed into key housing 23 in this embodiment by the action of a spring 27 housed in each of housings 24, as shown in Figure 3. However, Lock cylinders in which the rotor pins 25 and the stator pins 26 are pushed into the key housing 23 are known in the state of the art using other means such as magnets, discs, etc.
    [0055]
    [0056] The lock cylinder 2 further comprises a validation element 231 in the key housing 23 configured to be housed in the control recess 12 when the key 1 is inserted.
    [0057]
    [0058] The position in which the key 1 has been completely inserted into the lock cylinder 2 can be determined by the validation element 231, such that when said validation element 231 abuts the control recess 12, it defines said position. However, it is not necessary that the validation element 231 abuts the control recess 12 to define said position of the key 1 in the invention. The position where key 1 has been fully inserted into lock cylinder 2 may come also determined by a stop element 19, whose stop surface 190 abuts the front face 220 of the rotor 22, as shown in Figure 3. Once the key 1 has been fully inserted into the rotor 22, the Code surfaces 14 are arranged aligned and each in contact with the corresponding rotor pin 25, since each rotor pin 25 and stator pin 26 are pushed towards the key housing 23 by the corresponding spring 27. In said position, the contact surface between each of the rotor pins 25 and each of the stator pins 26 coincides with the outer surface 28 of the rotor 22, allowing the rotor 22 to rotate inside the stator 21.
    [0059]
    [0060] In the lock system 100 of the invention, the control recess 12 partially overlaps with at least one stator pin 26 when the key 1 has been fully inserted into the lock cylinder 2 and has been rotated to a position where the control recess 12 is confronted with said stator pin 26, the stator pin 26 acting as an additional locking element in case a fraudulent key is used with a control recess 12 that completely overlaps with said stator pin 26 Thus, the stator pin 26 performs a double function: on the one hand it cooperates with the code 14 surfaces and on the other it acts as an additional locking element. In this way a more secure lock system is obtained without increasing the number of elements of the lock system.
    [0061]
    [0062] Figure 4 shows a part of the lock system 100 of this embodiment, where the key 1 has been fully inserted into the lock cylinder 2 and has been rotated until the control recess 12 is arranged facing the farthest stator pin 26 of the front face 220 of the rotor 22. In addition, the control recess 12 partially overlaps with the stator pin 26 farthest from the front face 220 of the rotor 22, in such a way that the key blade 11 prevents the insertion of said stator python 26 in control recess 12.
    [0063]
    [0064] Conversely, if a fraudulent wrench is used with a control recess 12 that fully overlaps with the stator pin 26 farthest from the front face 220 of the rotor 22, said stator pin 26 slides into the recess of control12, and preventing rotation of the rotor 22, as shown in Figure 5.
    [0065]
    [0066] However, if a fraudulent key is used where control recess 12 does not have sufficient dimensions for validation element 231 to lodge in recess control 12 when the key 1 has been completely inserted into the lock cylinder 2, the validation element 231 abuts the control recess 12, preventing the key 1 from entering the lock cylinder 2 completely, so that the plurality of code surfaces 14 do not cooperate with the plurality of rotor pins 25, preventing rotor 22 from rotating.
    [0067]
    [0068] In this embodiment, the control recess 12 is disposed on the front face 115, on one of the minor side faces 111 and on the major side faces 113 and 114 of the key blade 11.
    [0069]
    [0070] In the lock system 100 of this embodiment, the control recess 12 partially overlaps in the transverse direction of the key 1 with the stator pin 26, as shown in Figure 4. In this embodiment, when the recess overlaps control 12 in the transverse direction of the key 1 with the stator pin 26, the control recess 12 partially overlaps with a single stator pin 26, the furthest from the front face 220 of the rotor 22. In the key 1 In this embodiment, the control recess 12 is arranged on the front face 115, on the minor lateral face 111 and on both major lateral faces 113 and 114.
    [0071]
    [0072] In another embodiment of the lock system 100, the control recess 12 partially overlaps in the longitudinal direction of the key 1 with the stator pin 26. In this other embodiment, the control recess 12 is arranged on the front face 115, in the minor lateral face 111 and in one of the major lateral faces 113 or 114, the control recess 12 being able to be extended in the longitudinal direction of the key 1. In this other embodiment, the control recess 12 overlaps at least with the spigot of stator 26 furthest from the front face 220 of rotor 22, or last stator pin, and it may overlap with more stator pins 26 depending on how long the control recess 12 is extended in the longitudinal direction of the key 1. Therefore depending on how long the control recess 12 is prolonged, said control recess 12 would go from overlapping only with the last stator pin 26 or stator pin 26 furthest from the front face 220 of the rotor 22, to sol mate with one or more additional stator pins 26, said overlapping being progressive as a function of the length of said control recess 12, beginning with the last stator pin 26 and ending with the first stator pin 26 or stator pin 26 plus close to the front face 220 of the rotor 22.
    [0073]
    [0074] In the lock system 100 of the embodiment shown in Figures 1 to 6, the element Validation 231 has a slope shape and extends longitudinally in a section of the key housing 23, decreasing its height in the opposite direction to the direction of insertion of the key 1, as shown in Figure 6.
    [0075]
    [0076] In the lock system 100 of this embodiment, the lock cylinder 2 comprises an additional validation element 232 following the validation element 231 in the opposite direction to the direction of introduction of key 1, and key 1 comprises a respective recess 13 configured to house additional validation element 232.
    [0077]
    [0078] In case of using a fraudulent key where the respective recess 13 does not have the sufficient dimensions so that the additional validation element 232 is lodged in the respective recess 13 when the key 1 has been completely inserted, the additional validation element 232 does abutment with the respective recess 13, preventing the key 1 from entering the lock cylinder 2 completely, so that the plurality of code surfaces 14 do not cooperate with the plurality of rotor pins 25, preventing the rotor 22 from rotating.
    [0079]
    [0080] In the lock system 100 of this embodiment the respective recess 13 of the key 1 is a longitudinal groove 15, as shown in Figures 1 and 2.
    [0081]
    [0082] In another embodiment of the lock system 100 of the invention, the respective recess 13 of the key 1 is an extension of the control recess 12.
    [0083]
    [0084] As shown in Figure 6, in the lock system 100 of this embodiment, the additional validation element 232 has a slope shape and extends longitudinally in a section of the key housing 23, decreasing its height in the opposite direction to key entry direction 1.
    [0085]
    [0086] In this embodiment of the lock system 100 of the invention, the code 14 surfaces of the lock key 1 are located on the minor side face 112 of the key blade 11 opposite to the minor side face 111 of the key blade 11 in which the control recess is located 12.
    [0087]
    [0088] In the lock system 100 of this embodiment, the control recess 12 partially overlaps with the stator pin 26 when the key 1 has been inserted into the lock cylinder. lock 2 fully and has been rotated 180 ° as shown in Figure 4.
    [0089]
    [0090] Figures 7 and 8 show a second embodiment of the lock system 100 of the invention. In this second embodiment, the code 14 surfaces of the lock key 1 are located on at least one major lateral face 113o114 of the lock key 1.
    [0091]
    [0092] In the lock system 100 of this second embodiment the control recess 12 partially overlaps with the stator pin 26 when the key 1 has been inserted into the lock cylinder 2 completely and has been rotated 90 ° or 270 °, the key 1 in the position shown in Figure 8.
    [0093]
    [0094] In the lock system 100 of the invention, the rotor 22 comprises an unlocking chamfer 221, as shown in Figure 5. In the case of using a fraudulent key with a control recess 12 that totally overlaps with at least the stator python 26 farthest from the front face 220 of the rotor 22, said stator python 26 slides, housed in the control recess 12, and preventing the rotor 22 from rotating, as shown in Figure 5. The chamfer Release 221 of rotor 22 allows key 1 to be rotated in the opposite direction, allowing rotor 22 to rotate in the opposite direction to that of opening and recovery of key 1 from lock cylinder 2.
    [0095]
    [0096] In the event that the control recess 12 totally overlaps with several stator pins 26, said stator pins 26 slide, staying in the control recess 12, and preventing the rotor 22 from rotating, allowing the unlocking chamfer 221 to key recovery 1.
