Definitions

  • the present invention belongs to the technical field of electronic locks.
  • this invention relates to a locking mechanism intended for use in electronic cylinder locks in which the closure system is provided with an eccentric.
  • the eccentric In mechanical cylinders, the eccentric is integrally attached to the rotor when the rotor is interlocked by the pins when the key is removed; the eccentric, being integrally attached to the rotor, is also interlocked. This, however, does not happen in electronic cylinders, and certain activation or locking functions of closures or systems are limited.
  • the actuating mechanism of the electronic cylinder lock in its resting position, is not connected to the eccentric, therefore it does not transmit any movement to the same.
  • the actuating mechanism engages with the eccentric. Once engaged, the eccentric can rotate and move in the desired way, allowing opening or closing. Once the operation is finished (in other words, once the door has been opened or closed), the electronic cylinder returns to its resting condition, disengaging itself.
  • the locking mechanism of the eccentric should be adapted to the reduced length of the cylinder in this type of locks.
  • the most commonly used cylinder in these locks is the European profile half cylinder, whose length is half that of a conventional cylinder, which is a major impediment when designing the locking mechanism.
  • the present invention aims to address all of the limitations, disadvantages and drawbacks of electronic cylinder locks from the prior art described above.
  • a first object of the invention relates to an eccentric locking mechanism for an electronic cylinder lock, characterised in that it comprises:
  • the operating procedure of the eccentric locking mechanism according to the present invention comprises the following steps:
  • the described locking situations of the eccentric correspond to the opening and closing positions of the lock, the eccentric always remaining locked when the lock is closed.
  • the locking mechanism according to the present invention can be used both in locks opening to the right and to the left.
  • the arrangement and shape of the recesses in the rotor insert is such that, when the rotor insert rotates the unlocking angle ( ⁇ ), the locking pin is positioned at the height of the inner edge of the bushing.
  • said rotor insert couples to the bushing in a coupling position, the following recess of the rotor insert also being aligned with the following opening in the bushing.
  • the bushing is provided with two openings spaced 90° apart, the rotor insert also being provided with two recesses spaced apart by an angle greater than or equal to 90° + ( ⁇ ), where ( ⁇ ) is the unlocking angle.
  • the rotor insert and bushing are positioned during the manufacturing process based on whether the lock opens to the right or to the left.
  • the bushing is provided with two openings spaced 180° apart, the rotor insert also being provided with two recesses spaced apart by an angle greater than or equal to 180° + ( ⁇ ), ( ⁇ ) being the unlocking angle.
  • This particular embodiment of the invention has the advantage that the locking mechanism can be used both with a lock that opens to the right and another that opens to the left (if the opening is to the right, closing occurs when the eccentric is located at 270°, and if, on the other hand, the opening is to the left, it will be the other way around, meaning the closing occurs when the eccentric is located at 90°). In this way a more universal solution is obtained.
  • the openings in the bushing preferably have chamfered and/or rounded walls. This particular shape of the walls of the openings makes it easier for the locking pin to completely come out of the corresponding opening once the bushing has been coupled to the rotor insert and the locking pin has been aligned with the inner edge of the bushing.
  • the coupling means comprise a window provided in the rotor insert and a lug provided in the bushing.
  • the coupling positions are reached when one of the lateral edges of the window of the rotor insert comes into contact with the corresponding lateral end of the lug, provided in the bushing.
  • the width of the window i.e., the distance between the lateral edges thereof
  • the length of the rotor insert window is such that, when the rotor insert rotates at least the unlocking angle ⁇ and the coupling position of the rotor insert with the bushing is reached, one of the recesses of the rotor insert is aligned with one of the openings in the bushing.
  • the coupling means comprise a window provided in the bushing and a lug provided in the rotor insert.
  • the coupling positions are reached when one of the lateral ends of the lug of the rotor insert comes into contact with the corresponding lateral edge of the bushing window. Therefore, in this embodiment, the width of the window also depends on the unlocking angle ⁇ .
  • the length of the bushing window is such that, when the rotor insert rotates at least the unlocking angle ⁇ and the coupling position of the rotor insert with the bushing is reached, one of the recesses of the rotor insert is aligned with one of the openings in the bushing.
  • the eccentric is provided with an anchoring pin loaded with a coil spring and, moreover, the bushing is provided with holes intended to house said anchoring pin of the eccentric. Thanks to this particular configuration of the mechanism of the invention, it is possible to place the eccentric in different positions and choose, during the lock installation operation by the user, the position in which the closure is best secured (it does not always have to close at 90° or 270°).
  • a second object of the invention relates to an electronic cylinder lock, characterised in that it is provided with a locking mechanism according to the first aspect of the invention.
  • Figure 1 shows a first eccentric locking mechanism according to the present invention.
  • the locking mechanism comprises a stator body (1), which has a hollow cylindrical inner portion or inner core (1a).
  • the stator body (1) is provided with a borehole (2) inside which the locking pin (3), the spring (4) and a closing plug (11) are housed.
  • the stator body (1) is provided with a mortise (12) that allows the passage of an eccentric (10) in its rotation.
  • a bushing (7) is also inserted in the inner core (1a) coaxially with the rotor insert (5) and externally to the same.
  • the bushing is also provided with openings (8) intended to house the locking pin (3).
  • the openings (8) have chamfered and/or rounded walls.
  • the coupling means responsible for coupling the rotor insert (5) to the bushing (7) during the activation of the electronic lock, comprise a lug (9b) provided in the bushing (7) and a window (9a) made in the rotor insert (5).
  • Figure 2 shows in greater detail how the rotor insert (5) and the bushing (7) are coupled once one of the lateral edges of the window (9a) of the rotor insert (5) comes into contact with one of the lateral ends of the lug (9b) of the bushing (7).
  • Figure 2 shows more clearly how, in this embodiment of the invention, the bushing (7) is provided with a notch (7a) to house a clip for axial attachment of the bushing (20) to the stator body (1).
  • the rotor insert (5) is provided with a slot (19) to house a clip for axial attachment of the rotor insert (21) to the stator body (1).
  • FIG. 3A-3D and 4A-4D A second embodiment of the locking mechanism of the present invention is shown in Figures 3A-3D and 4A-4D .
  • Said mechanism is very similar to the one illustrated in Figure 1 , but the coupling means vary slightly: here the window (9d) is made in the bushing (7), whereas the lug (9c) is provided in the rotor insert (5).
  • the eccentric (10), the attachment clips and the spring (4) have been removed to be able to see how the other elements move during the operation of the locking mechanism.
  • Figures 3A and 4A show an initial locked position of the mechanism of the invention.
  • the locking pin (3) due to the action of the spring (4), has passed through one of the openings (8) in the bushing (7) reaching a corresponding recess (6) of the rotor insert (5) aligned with said opening (8).
  • the bushing (7) is locked by the locking pin (3).
  • Figures 3B and 4B represent the moments immediately after the activation of the electronic lock.
  • the rotor insert (5) engages with a transmission mechanism between the rotor and rotor insert of the lock and begins to turn inside the bushing (7) and, thanks to the shape of its recesses (6), pushes the locking pin (3) into the borehole (2).
  • the rotor insert (5) turns a total unlocking angle ( ⁇ ) until the locking pin (3) is at the same height as the inner edge of the bushing (7).
  • the rotor insert (5) is coupled to the bushing (7) when it has rotated at least the total unlocking angle ( ⁇ ), and the situation may arise where it is necessary to rotate an angle greater than the total unlocking angle ( ⁇ ) so that coupling between the rotor insert (5) and the bushing (7) occurs.
  • ⁇ total unlocking angle
  • one of the lateral ends of the lug (9c) of the rotor insert (5) comes into contact with a lateral edge of the window (9d) provided in the bushing (7).
  • Figures 3C and 4C represent a subsequent step in which the rotor insert (5) continues its rotation coupled to the bushing (7). Thanks to the drag of the rotor insert (5) and the fact that the locking pin (3) is aligned with the inner edge of the bushing (7), the wall of the opening (8) in the bushing (7), in which the locking pin (3) was interlocked thanks to its shape, exerts pressure on said locking pin (3) during rotation, pushing it inside the borehole (2) against the action of the spring (4) until the locking pin (3) completely comes out of said opening (8). Once out of the opening (8), the bushing (7), being released from the locking pin (3), is free to rotate in the direction of rotation induced by the rotor insert (5).
  • Figures 3D and 4D show the final step, in which the bushing (7) continues to rotate until it reaches a position in which the following opening (8) is aligned with the locking pin (3). In this way, as in the first step described, the bushing (7) (and by extension, the eccentric (10) of the electronic lock) are locked again.
  • the described locking situations of the eccentric (10) correspond to the opening and closing positions of the lock, the eccentric always remaining locked when the lock is closed.
  • this locking mechanism can be used in locks that open to both the right and the left.
  • the arrangement of the recesses (6) in the rotor insert (5) and the arrangement of the openings (8) in the bushing (7) is such that, when the rotor insert (5) rotates at least the unlocking angle ⁇ ° and couples to the bushing (7) in a coupling position, the following recess (6) of the rotor insert (5) is aligned with the following opening (8) in the bushing (7).
  • the rotor insert (5) is provided with two recesses (6) spaced apart by an angle greater than or equal to 180° + ⁇ , the bushing (7) also being provided with two openings (8) spaced 180° apart.
  • This first embodiment of the invention has the advantage that the locking mechanism can be used both with a lock that opens to the right and another that opens to the left (if the opening is to the right, closing occurs when the eccentric is located at 270°, and if, on the other hand, the opening is to the left, it will be the other way around, meaning the closing occurs when the eccentric is located at 90°). In this way a universal solution is obtained.
  • the rotor insert (5) is provided with two recesses (6) spaced apart by an angle greater than or equal to 90° + ⁇ , the bushing (7) also being provided with two openings (8) spaced 90° apart.
  • the positioning of the rotor insert (5) and bushing (7) is carried out at the factory depending on whether the lock opens to the right or to the left.
  • FIGS 5A to 5D are cross-sectional views of a locking mechanism according to the present invention, wherein the eccentric (10) has been represented so as to show the eccentric locking process by means of a locking mechanism according to the present invention.
  • the arrows located on the rotor insert (5) represent the direction of rotation.
  • FIGS 5A to 5D will explain different operating options provided by the first embodiment of the locking mechanism object of the present invention.
  • the eccentric (10) is locked in the 270° position (i.e., pointing to the left) by the locking pin (3).
  • the lug (9b) does not act because the coupling between the rotor insert (5) and the bushing (7) has not yet taken place.
  • Figure 5C shows that by continuing the 90° anticlockwise rotation of the rotor insert (5), it engages with the bushing (7), causing it to turn and displacing the locking pin (3) towards the inside of the borehole (2) thanks to the chamfered and/or rounded walls of the opening (8).
  • the eccentric (10) turns until it is hidden in the mortise (12) of the stator body (1), reaching the open position.
  • Figure 5D shows how, if the user wants to leave the eccentric (10) also locked at 90° (i.e., pointing to the right), from the position illustrated in Figure 5C he or she can continue rotating the rotor insert (5) coupled to the bushing (7) another 90° in the anticlockwise direction until the locking pin (3) enters a new opening (8) so that it locks the eccentric (10) at 90°.
  • This position of the eccentric (10) locked in Figure 5D after having carried out the movements of the previous Figures 5A to 5C , can be a new closing position of the lock or an opening position where it is of interest to have the eccentric (10) locked.
  • Figures 6A to 6D show an additional embodiment of a locking mechanism according to the present invention which allows the locking positions of the eccentric (10) to be adjusted, wherein the eccentric (10) is provided with an anchoring pin (13) loaded by a coil spring (14) and furthermore the bushing (7) is provided with holes (15) intended to house said anchoring pin (13).
  • the holes (15) of the bushing (7) are provided every 30°.
  • an indicator (16) can be provided, which can be for example a sticker, that illustrates the position of the different angles that the holes are at (marked as 30°, 60°, 90°, and so on).
  • the locking mechanism according to Figures 6A to 6D has the advantage that it allows the eccentric (10) to be placed in different positions (in this case, there is a different hole (15) every 30°) and to choose, during the lock installation operation by the user, the position in which the closure is best secured.
  • a groove (17) is provided, through which the user can insert a screwdriver or other similar tool into the indentation (18) of the anchoring pin (13) and pull it upwards until it is removed from the hole (15) in which it was fitted, to release the eccentric (10) and place it in the desired position.
