Description

Lock system with key and lock cylinder

Technical Field

The present invention relates to a lock system having a key and a cylinder.

Background

It is known to use lock systems comprising a key and a cylinder.

This type of lock system comprises a key with a key blade (blade) which has 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 receiving portion present in the lock cylinder. The key cylinder comprises a stator and a rotor rotating inside the stator, which is provided with a plurality of receptacles, such that in each of the receptacles a rotor pin and a stator pin are received which can be displaced in the radial direction of the key cylinder, such that when an active key blade is fully inserted into the key cylinder, the rotor pin and the stator pin are positioned in accordance with a code, thereby enabling the rotor to rotate, which results in the lock being opened.

EP2360334B1 describes a lock system in which the lock cylinder comprises a verification element which extends at least partially into the key channel, and in which the key comprises a control recess which is configured such that it corresponds to the locking element, so that the locking element is accommodated in the recess when the key is inserted into the key channel. In the lock system described in document EP2360334B1, the recess is longer than the length along which the locking element is inserted into the recess.

Disclosure of Invention

It is an object of the present invention to provide a lock system as defined in the claims.

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 after the other in the longitudinal direction of the key blade.

The lock system of the present invention also includes a lock cylinder. The key cylinder includes a stator and a rotor configured to rotate in an opening of the stator, the rotor including a key receiving portion configured to receive a key. The lock cylinder further comprises a plurality of receiving portions, each receiving at least one rotor pin and one stator pin, which are displaceable in a radial direction of the lock cylinder, the code surfaces of the rotor pin and the key being configured to cooperate with each other when the key has been fully inserted into the lock cylinder. The lock cylinder further includes an authentication element located in the key receiving portion, the authentication element configured to be received in the control recess when the key is inserted.

In the lock system of the invention, the control recess partially overlaps with the stator pin when the key has been fully inserted into the lock cylinder and rotated to a position in which the control recess faces at least one stator pin, which stator pin serves as an additional locking element in the case of using a counterfeit key having a control recess that fully overlaps with the stator pin. The stator pin thus has a dual function, increasing the security provided by the locking system without increasing the number of elements of the locking system.

These and other advantages and features of the present invention will become apparent in view of the drawings and detailed description of the invention.

Detailed Description

Fig. 1 to 6 relate to a first embodiment of a lock system 100 according to the invention.

The lock system 100 of the present invention includes a lock key 1 having a key blade 11. The key blade 11 comprises a front face 115, two larger side faces 113, 114 and two

smaller side faces

111, 112.

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.

The lock system 100 of the present invention also includes a lock cylinder 2. The key cylinder 2 includes a stator 21 and a rotor 22. The rotor 22 is configured to rotate in the opening of the stator 21, and includes a key receiving portion 23 configured to receive the key blade 11. The key receiving portion 23 extends longitudinally along the rotor 22 and includes an access opening on the front face 220 of the rotor 22.

The key cylinder 2 further comprises a plurality of receptacles 24, each receptacle 24 accommodating at least one rotor pin 25 and one stator pin 26 which are displaceable in a radial direction of the key cylinder 2, the rotor pins 25 and the code surface 14 being configured to cooperate with each other when the key 1 has been fully inserted into the key cylinder 2. As shown in fig. 3, in this embodiment, the rotor pin 25 and the stator pin 26 are urged toward the key accommodating portion 23 by the action of the spring 27 accommodated in each accommodating portion 24. However, it is known in the art to use other means such as magnets, discs, etc. to push the rotor pins 25 and the stator pins 26 toward the key cylinder of the key receiving portion 23.

The lock cylinder 2 further comprises an authentication element 231 located in the key receiving portion 23, the authentication element 231 being configured to be received in the control recess 12 when the key 1 is inserted.

The position in which the key 1 has been fully inserted into the lock cylinder 2 can be determined by the verification element 231, so that when said verification element 231 abuts the control recess 12, it defines said position. However, in the present invention, the verification element 231 does not necessarily have to abut against the control recess 12 to define said position of the key 1. The position in which the key 1 has been fully inserted into the lock cylinder 2 can also be determined by the stop element 19, the stop surface 190 of the stop element 19 abutting the front face 220 of the rotor 22, as shown in fig. 3. Once the key 1 has been fully inserted into the rotor 22, the code surfaces 14 are arranged so that each code surface is aligned and contacts a corresponding rotor pin 25, with each rotor pin 25 and stator pin 26 being urged towards the key receptacle 23 by a corresponding spring 27. In said position, the contact surface between each rotor pin 25 and each stator pin 26 coincides with the outer surface 28 of the rotor 22, allowing the rotor 22 to rotate inside the stator 21.

In the lock system 100 of the invention, when the key 1 has been fully inserted into the lock cylinder 2 and rotated to a position in which the control recess 12 faces at least one stator pin 26, the control recess 12 partially overlaps said stator pin 26, the stator pin 26 acting as an additional locking element in the case of a forged key with a control recess 12 that completely overlaps said stator pin 26. Thus, the stator pin 26 has a dual function: on the one hand, it cooperates with the code surface 14 and, on the other hand, it serves as an additional locking element. A more secure locking system is thereby obtained without increasing the number of components of the locking system.

Fig. 4 shows a part of the lock system 100 of this embodiment, wherein the key 1 has been fully inserted into the lock cylinder 2 and rotated until the control recess 12 is arranged facing the stator pin 26 furthest away from the front face 220 of the rotor 22. Furthermore, the control recess 12 partially overlaps the stator pin 26 furthest away from the front face 220 of the rotor 22, so that the key blade 11 prevents the insertion of said stator pin 26 into the control recess 12.

In contrast, if a counterfeit key having the control recess 12 completely overlapping the stator pin 26 farthest from the front face 220 of the rotor 22 is used, the stator pin 26 slides into the control recess 12, is accommodated in the control recess 12, and prevents the rotor 22 from rotating, as shown in fig. 5.

However, in the case of using a counterfeit key in which the size of the control recess 12 is insufficient to accommodate the authentication element 231 in the control recess 12 when the key 1 has been fully inserted into the key cylinder 2, the authentication element 231 abuts against the control recess 12, preventing the key 1 from being fully inserted into the key cylinder 2, so that the plurality of code surfaces 14 are not engaged with the plurality of rotor pins 25, thereby preventing the rotor 22 from rotating.

In this embodiment, the control recess 12 is arranged on the front face 115 of the key blade 11, on one of the smaller side faces 111 and on the larger side faces 113 and 114.

In the lock system 100 of this embodiment, the control recess 12 partially overlaps the stator pin 26 in the lateral direction of the key 1, as shown in fig. 4. In this embodiment, when the control recess 12 overlaps the stator pin 26 in the transverse direction of the key 1, the control recess 12 partially overlaps the single stator pin 26, which stator pin 26 is the stator pin 26 furthest from the front face 220 of the rotor 22. In the key 1 of this embodiment, the control recess 12 is arranged on the front face 115, on the smaller side face 111, and on the two larger side faces 113 and 114.

In another embodiment of the lock system 100, the control recess 12 partially overlaps the stator pin 26 in the longitudinal direction of the key 1. In this further embodiment, the control recess 12 is arranged on the front face 115, on the smaller side face 111 and on one of the larger side faces 113 or 114, wherein the control recess 12 can be elongated in the longitudinal direction of the key 1. In this further embodiment, the control recess 12 overlaps at least the stator pin 26 that is furthest away from the front face 220 of the rotor 22 or the last stator pin, wherein the control recess 12 may overlap more stator pins 26 depending on how much the control recess 12 is elongated in the longitudinal direction of the key 1. Thus, depending on how much the control recess 12 is elongated, said control recess 12 will overlap from only the last stator pin 26 or the stator pin 26 furthest from the front face 220 of the rotor 22 to one or more additional stator pins 26, said overlap progressing according to the length of said control recess 12, starting from the last stator pin 26 and ending to the first stator pin 26 or the stator pin 26 closest to the front face 220 of the rotor 22.

In the lock system 100 of the embodiment shown in fig. 1 to 6, the verification element 231 is in the form of a ramp and extends longitudinally in a section of the key receiving portion 23, the height of the verification element 231 decreasing in a direction opposite to the direction in which the key 1 is inserted, as shown in fig. 6.

In the lock system 100 of this embodiment, the lock cylinder 2 comprises, in a direction opposite to the direction of insertion of the key 1, an additional authentication element 232 located behind the authentication element 231, and the key 1 comprises a corresponding recess 13, the corresponding recess 13 being configured to accommodate the additional authentication element 232.

In the case of using a forged key in which the size of the respective recess 13 is insufficient to accommodate the additional authentication element 232 in the respective recess 13 when the key 1 has been fully inserted, the additional authentication element 232 abuts the respective recess 13, preventing the key 1 from being fully inserted into the key cylinder 2, so that the plurality of code surfaces 14 are not engaged with the plurality of rotor pins 25, thereby preventing the rotor 22 from rotating.

In the lock system 100 of this embodiment, the corresponding recess 13 of the key 1 is a longitudinal groove 15, as shown in fig. 1 and 2.

In another embodiment of the lock system 100 of the invention, the corresponding recess 13 of the key 1 is an extension of the control recess 12.

As shown in fig. 6, in the lock system 100 of this embodiment, the additional verification element 232 is in the form of a slope and extends longitudinally in a section of the key receiving portion 23, and the height of the additional verification element 232 decreases in a direction opposite to the direction in which the key 1 is inserted.

In this embodiment of the lock system 100 of the present invention, the combination surface 14 of the lock key 1 is located on a minor side 112 of the key blade 11, the minor side 112 being opposite to the minor side 111 of the key blade 11 where the control recess 12 is located.

In the lock system 100 of this embodiment, as shown in fig. 4, when the key 1 has been fully inserted into the key cylinder 2 and rotated by 180 °, the control recess 12 partially overlaps with the stator pin 26.

Fig. 7 and 8 show a second embodiment of the lock system 100 of the present invention. In this second embodiment, the code surface 14 of the lock key 1 is located on at least one

larger side

113 or 114 of the lock key 1.

In the lock system 100 of this second embodiment, when the key 1 has been fully inserted into the lock cylinder 2 and rotated 90 ° or 270 ° (the key 1 is arranged in the position shown in fig. 8), the control recess 12 partially overlaps with the stator pin 26.

In the lock system 100 of the present invention, the rotor 22 includes an unlocking ramp 221, as shown in FIG. 5. In the case of using a counterfeit key having a control recess 12 that completely overlaps at least the stator pin 26 farthest from the front face 220 of the rotor 22, the stator pin 26 slides into the control recess 12 to be accommodated in the control recess 12, thereby preventing the rotor 22 from rotating, as shown in fig. 5. The unlocking ramp 221 of the rotor 22 allows the key 1 to be rotated in the opposite direction, allowing the rotor 22 to be rotated in the opposite direction to the opening direction, and allowing the key 1 to be withdrawn from the key cylinder 2.

In the case where the control recess 12 completely overlaps the plurality of stator pins 26, the stator pins 26 are slid into the control recess 12 to be received in the control recess 12, thereby preventing the rotor 22 from rotating, and the unlocking slope 221 allows the key 1 to be retracted.
