    Description

    Technical field



    [0001] The invention relates to a mechatronic cylinder lock comprising a housing in which is rotatably mounted a mechanical coding part of the lock with a key channel for a profiled key shank, whereby the mechanical coding part of the lock is coupled to at least one rotatable element for transmitting rotary motion of the key to a lock detent and the housing accommodates at least one blocking element of rotation of the mechanical coding part of the lock, which is coupled to an electronically controlled unblocking means, which is provided with means for communication with an electronic control means in the key.

    Background art



    [0002] With the development of technology, synergistic effects of mechanical and electronic elements find application in more and more fields, giving rise to mechatronic solutions.

    [0003] In the field of locks, mechatronic solutions are used especially so as to increase the coding capabilities of the lock-key system.

    [0004] The mechatronic concept of such locks generally consists in that a displaceable mechanical element of the lock is associated in a suitable way with a blocking means, which is controlled, or triggered, electronically on the basis of the interaction between the electronics in the key and the electronics in the lock.

    [0005] US 5,826,450 A discloses a locking device with at least one key and a cylinder core with tumblers. The cylinder core is rotatably mounted in a housing and is provided with a key channel into which extend mechanical tumblers, which are associated both with the cylinder core and with the housing and which serve to block and release the rotation of the cylinder core depending on a proper key inserted into the key channel. In the housing below the cylindrical core a blocking element of the rotation of the cylinder core is disposed, being arranged reciprocatingly slidably, spring-loaded with compression springs. This blocking element is associated to a control element connected to a drive. In principle, the control element of the blocking element is displaceable by the drive between two positions, namely the blocking position and the release position. In the blocking position, the blocking element extends to at least one recess arranged on the cylindrical circumference of the cylinder core, spaced from the key channel. Consequently, the key never comes into contact with the blocking element. In this position, the control element of the blocking element is at the same time in such a position that it abuts the lower surface of the blocking element, which therefore cannot be moved out of its blocking position, i.e., it is blocked in this position, and the cylinder core cannot be turned in the lock housing even if a proper key is inserted. On the other hand, in the release position of the blocking element, the control element of the blocking element no longer prevents the blocking element from being pushed into the lower part of the housing, thereby enabling the cylinder core to turn, with a proper key inserted. The above-mentioned control element of the blocking element is formed, for example, by a flat body, which is mounted on a rotatable shaft of the control drive in a gap between the lower surface of the blocking element and the bearing surface of the housing, whereby the transverse dimension of the blocking element in one direction corresponds to the size of the gap between the bottom surface of the blocking element and the bearing surface of the housing in the blocking position of the blocking element and the transverse dimension of the blocking element in a direction perpendicular to the first direction is substantially smaller, thereby meeting the requirement for creating a sufficiently large free space below the rotatable cylinder core for pushing in the blocking element by rotating the cylinder core outside the profile of the rotation of the cylinder core, i.e. into the release position. The drive of the control element is connected to electronics mounted in the upper part of the housing, the electronics including a receiver of a control signal, the transmitter of which is arranged in the key, which thus serves as a data carrier containing identification data. Data transission is wireless. The drive of the control element is further connected to a source of electrical energy, which is accommodated in the housing, for example, in the lower part of the housing of the other side of the double-sided cylinder lock. The key is not provided with a source of energy; energy is supplied to the electronics of the key by VF wireless transmission on approaching the lock and by induction in a coil in the key.

    [0006] However, the drawback of this background art is the need to perform correcting operation in the rotary part of the lock for mechanical coding of the lock-key system, which limits the capabilities of mechanical coding. Another drawback is the arrangement of the power source in the lock, which in case of a capacity decrease of the source leads to the need to replace the whole lock and increases the risk of sudden failure of the lock in the event of a power failure.

    [0007] EP 2 765 263 A1 discloses a mechatronic cylinder lock comprising a housing, in which is rotatably mounted a mechanical coding part of the lock with a key channel for a profiled shank of the key. The housing accommodates at least one element for blocking the rotation of the mechanic coding part of the lock, which is coupled to an electronically controlled unblocking means, which is provided with means for communication with the electronic control means in the key. A radial recess is formed in the mechanic coding part and a contact element of the electronically controlled blocking system of the rotation of the mechanical coding part of the lock is placed in this recess. A part of the contact element can extend into the key channel. An opposite part of the contact element abuts the upper surface of a spring-loaded blocking tow bar, which is mounted slidably reciprocatingly in the housing of the lock. In the blocking position one end of the tow bar extends to the radial recess in the mechanical coding part whereas in the release position it is pushed out of the radial recess by the rotation of the mechanical coding part. The blocking tow bar is provided with a surface, against which in the blocking position a flat spacer cam is arranged with its wider dimension. This spacer cam is displaceable between the blocking position and a release position and is mounted on a movable element of an electrical drive. The blocking tow bar is further provided with a lateral arm, which extends to the plane of the axis of the rotation of the flat spacer cam and is at this point bent towards the axis of rotation of the flat spacer cam and extends as far as to the lateral surface of the flat spacer cam in the narrower transverse dimension of the flat spacer cam.

    [0008] A further similar mechatronic cylinder lock is disclosed in FR 2 849 083 A1.

    [0009] The goal of the invention is to find an alternative arrangement of the cylinder lock elements.

    Principle of the invention



    [0010] The goal of the invention is achieved by a mechatronic cylinder lock according to claim 1.

    [0011] The mechatronic cylinder lock according to the invention essentially differs from the state of the art in that the mechanical coding part of the lock is coupled to at least one rotatable element for transmitting rotary motion of the key to a lock detent.

    [0012] According to the invention, in the at least one rotatable element is thereby formed a radial recess, into which extends the working part of a contact element of the electronically controlled blocking system of the rotation of the mechanical coding part of the lock, whereby the contact element extends by the upper part of its working part into the key channel and at the same time extends to the radial recess in the end part of the mechanical coding part of the lock and abuts by its lower part the upper surface of the spring-loaded blocking tow bar.

    [0013] The advantage of this solution is reliability and relatively easy applicability in different specific designs of locks with a rotatable cylindrical core provided either with disc tumblers or with cylinder tumblers, etc. Another advantage is the fact that the invention enables to maintain the existing functions of the mechanical lock, while adding new functions to them in a suitable way and using avaliable means. Another benefit is the fact that the lock returns to the blocked state of the electronically controlled blocking mechanism automatically, all by itself and without the need for energy from the battery of the key thanks to the spring-loaded blocking tow bar and its lateral arm, which in its release position extends below the spacer cam.

    Examples of embodiment



    [0015] The invention will be described on an example of arrangement of a cylinder lock with a cylinder core having disc tumblers. However, the invention is also applicable to a cylinder lock with a cylinder core having cylinder tumblers radially arranged, as well as to other types of locks.

    [0016] The lock comprises a housing 1, in which the individual elements of the lock are arranged. The housing 1 is unified into a standard form. In the upper part 10 of the housing 1 is arranged a mechanical coding part 2 of the lock, in this case comprising a set of disc tumblers 20, separating discs 21 and other elements for creating a disc mechanical coding part 2 of the lock. The disc mechanical coding part 2 of the lock is along its length provided with a known key channel for inserting a profiled shank 40 of the key 4. In the key channel, a longitudinal guide 8 of the key 4 is arranged in a known manner.

    [0017] From the front end of the mechanical coding part 2 of the lock, an inlet opening 3 for the profiled shank 40 of the key 4 is formed in the housing 1 for inserting the shank 40 of the key 4 into the key channel. At its rear end, the disc mechanical coding part 2 of the lock is coupled to rotatable elements 5 for transmitting the rotary movement of the key 4 to the lock detent 7, e.g., through a coupling 6.

    [0018] In at least one rotatable element 5 is formed a radial recess 50, or a radial groove, into which extends the working part of a contact element 90 of an electronically controlled blocking system 9 of the rotation of the mechanical coding part 2 of the lock. In the exemplary embodiment shown in Fig. 7a, the contact element 90 is swingingly mounted in the rotatable element 5, being spaced from its working part. At the same time, the contact element 90 extends by the upper part 900 of its working part as far as to the key channel, more precisely, to the end of the key channel, extending in this position to the radial recess 22 in the end part of the mechanical coding part 2 of the lock, as is shown in Figs. 1a, 1b and 2a, thereby blocking the rotation of the mechanical coding part 2 of the lock without a key 4 having been properly inserted. The lower part of the contact element 90 abuts the upper surface 910 of a blocking tow bar 91, which is mounted slidably reciprocatingly in the lower part 11 of the housing 1 of the lock, whereas its upper end in certain positions, as will be described below, extends as far as to the radial recess 50 in the rotatable element 5 in such a manner as to block the rotation of the rotatable element 5 and, in combination, also the rotation of the mechanical coding part 2 of the lock.

    [0019] The blocking tow bar 91 is spring-loaded by a compression spring 92, by which it is pressed against the lower surface of the contact element 90. The compression spring 92 is mounted at its lower end in the lower part 11 of the housing 1 and its upper end rests on the bearing surface on the lower side of the blocking tow bar 91. In addition, the blocking tow bar 91 is on its lower side provided with a distance spacer pin 911, whose lower end 9110 is disposed opposite the blocking surface 9300 of the flat spacer cam 930, the flat spacer cam 930 being rotatably mounted on a shaft of a rotary electric drive 93. The blocking surface 9300 of the flat spacer cam 930 is formed by the peripheral surface of the flat spacer cam 930 in the largest transverse dimension of the flat spacer cam 930. In the basic position before insertion of the key 4 (Fig. 1b) into the key channel, the lower end 9110 of the spacer pin 911 is spaced from the blocking surface area 9300 of the flat spacer cam 930.

    [0020] The blocking tow bar 91 is further provided with a lateral arm 912, which is situated in a downward direction and in the basic position before insertion of the key 4 (Fig. 1b) extends to the plane of the axis of rotation of the flat spacer cam 930 and is bent there (bending 9120) towards the axis of rotation of the flat spacer cam 930, and extends to the lateral surface 9301 of the flat spacer cam 930 in the narrower transverse dimension of the flat spacer cam 930, i.e. inside the circle circumscribed by the blocking surface 9300 of the flat spacer cam 930 according to changes in the position of the flat spacer cam 930.

    [0021] In the illustrated exemplary embodiment, the blocking tow bar 91 is formed by a flat plate, whose surface (plane) is arranged perpendicularly to the longitudinal axis of the mechanical coding part 2 of the lock. This flat plate is rounded at its upper end forming an upper area 910, whereby it is further provided with a trio of arms directed downwards, the middle arm constituting a spacer pin 911, one outer arm constituting a lateral arm 912 with a bending 9120, the other outer arm constituting the other part of the longitudinal guide of slidable reciprocating movement of the blocking tow bar 91. Similarly, the first part of the longitudinal guide of slidable reciprocating movement of the blocking tow bar 91 is formed by a lateral arm 912 with a bending 9120.

    [0022] The rotary electric drive 93 is mounted in the lower part 11 of the housing 1, parallel to the mechanical coding part 2 of the lock. The rotary electric drive 93 is via the electronic control device 94 coupled to a feeding capacitor 95, which is also mounted in the lower part 11 of the housing 1.

    [0023] The electronic control device 94 and the feeding capacitor 95 are connected via a line 96 in the front part of the housing 1 to an annular collector 97, which is arranged along the circumference of one of the inlet rings 23 of the mechanical coding part 2 of the lock, whereby at least at one defined point of this circumference, the annular collector 97 is via a radially situated assembly consisting of a conductive pin 971 - contact cap 970, illustrated in Fig. 6, connected to an electric and data contact 41 on the shank 40 of the key 4. The contact cap 970 thus by its nature constitutes the electric and data contact of the lock. The assembly consisting of the conductive pin 971 and the contact cap 970 is in the illustrated exemplary embodiment mutually expanded by the compression spring 972. Consequently, the head 9710 of the conductive pin 971 is permanently pressed against the inner surface of the annular collector 97 and at the same time the rounded front end of the contact cap 970 is pushed into the key channel, i.e., with the key 4 inserted, it is forced into contact with the electric and data contact 41 on the shank 40 of the key 4.

    [0024] The electric and data contact 41 on the key is by the line 410 coupled to the electronics 42 of the key 4. The electronics 42 of the key 4 comprises, among other things, also a battery, preferably a replaceable battery, as a power source for the assembly consisting of the key 4 and the lock, as will be described below.

    [0025] The solution according to the invention operates in such a way that, in the initial state, in Figs. 1, 1a and 1b, i.e., when a key 4 with a properly profiled shank 40 is not inserted into the key channel, the contact element 90 of the electronically controlled blocking system 9 blocks the rotation of the mechanical coding part 2 of the lock by its presence in the radial recess 22 in the end part of the mechanical coding part 2 of the lock. Simultaneously, the blocking tow bar 91 is pushed by the compression spring 92 into the radial recess 50 in the rotatable element 5, thereby blocking the rotation of the rotatable element 5. The blocking surface 9300 of the flat spacer cam 930 is situated opposite the lower end 9110 of the spacer pin 911 of the blocking tow bar 91. To improve resistance of the flat spacer cam 930 against unwanted rotation when unlocking merely by the pressure of the lower end 9110 of the spacer pin 911 of the blocking tow bar 91, the flat spacer cam 930 is in the basic position set as "slightly" overturned behind the dead center in the opposite direction to its rotation during unlocking, whereby in this position, the lateral walls 9301 of the flat spacer cam 930 are aligned with stops 12 mounted in the lower part 11 of the housing 1. Furthermore, in this position of the flat spacer cam 930, suitable magnets can be built into at least one of the adjacent walls of the housing for retaining the flat spacer cam 930 in this initial position.

    [0026] After inserting a key 4 with a properly profiled shank 40 into the proper depth, which is determined by a stop of an appropriate configuration arranged on the key or in the system of the lock or in a lock-key 4 assembly, see Figs. 2 and 2a, the front end 400 of the shank 40 of the key 4 pushes onto the upper part 900 of the contact element 90 of the electronically controlled blocking system 9 of the rotation of the mechanical coding part 2 of the lock, which results in turning the contact element 90 and pushing the upper part 900 of the contact element 90 out of the radial recess 22 in the end part of the mechanical coding part 2 of the lock slightly downwards outside this recess 22. Consequently, the rotation of the mechanical coding part 2 of the lock is no longer blocked. In this position, also the compression spring 92 of the blocking tow bar 91, is partially compressed, while the blocking tow bar 91 by its lower end 9110 of its spacer pin 911 closely approaches the opposite blocking surface 9300 of the flat spacer cam 930, or it even abuts this surface. In addition, the flat spacer cam 930 does not allow inserting the blocking tow bar 9 more deeply, whereby the upper end of the blocking tow bar 9 is still inserted into the radial recess 50 in the rotatable element 5, thereby blocking the rotation of the rotatable element 5. Simultaneously, the bending 9120 of the lateral arm 912 shifts downwards, below the plane of the axis of rotation of the flat spacer cam 930.

    [0027] After inserting a key 4 to the proper depth, the electrical and data contact (not shown) in the lock comes into contact with the contact 41 on the shank 40 of the key 4, by which means the feeding capacitor 95 of the electronically controlled locking system 9 of the mechanical coding part 2 of the lock is charged from the battery of the electronics 42 in the key 4. This also activates the electronic control device 94 of the electronically controlled blocking system 9 of the mechanical coding part 2 of the lock, which receives the key identifier 4 via the feeding line by means of a coded signal from the electronics 42 of the key 4 and compares the identifier with the identifiers stored in the internal memory of the electronic control device 94. If the identifier of the key 4 matches the identifier (or one of the identifiers) stored in the internal memory of the electronic control device 94, the electronic control device 94 issues a command, whereupon the rotary electric drive 93 turns the flat spacer cam 930 into a position in which the lateral surface 9301 of the flat spacer cam 930 in the narrower transverse direction of the flat spacer cam 930 is situated opposite the lower end 9110 of the spacer pin 911 of the blocking tow bar 91, as shown in Fig. 3a, wherein the flat spacer cam 930 is turned by 90°. In addition, this increases the free space between the lower end 9110 of the spacer pin 911 of the blocking tow bar 91 and the now opposite lateral surface 9301 of the flat spacer cam 930, which allows the blocking tow bar 91 to be pushed further in a downward direction by continued rotation of the key 4, through continued rotation of the key 4 for positioning the disc tumblers 20 to the initial unlocking position of the mechanical coding part 2 of the lock, which is shown in Figs. 4 and 4a, since so far only the mechanical coding part 2 of the lock has been rotating. Due to continued rotation of the key 4, the mechanical coding part 2 of the lock will now be rotated again, this time also together with the rotatable elements 5, pushing the blocking tow bar 91 further on in the downward direction, this time as a result of the lower surface of the contact element 90 acting on the upper surface 910 of the blocking tow bar 91, which causes the lower end 9110 of the spacer pin 911 of the blocking tow bar 91 to approach (or abut) towards/on the lateral surface 9301 of the flat spacer cam 930, while the bending 9120 of the lateral arm 912 moves away from the adjacent lateral wall 9301 of the flat spacer cam 930, as is shown in Figs. 5 and 5a. This further turning of the mechanical coding part 2 of the lock together with the rotatable elements 5 results in turning also the lock detent 7. The lock is now unlocked.

    [0028] After drawing the key out of the lock, the key 4 must be brought back to the initial position by turning, by which means also the mechanical coding part 2 of the lock with the rotatable elements 5 of the lock is turned to the initial position. During that operation, at first the radial recess 50 in the rotatable element 5 and with the contact element 90 opposite the blocking tow bar 91 is set, whereby the blocking tow bar 91 is due to the action of the compression spring 92 pushed into this radial recess 50 in the rotatable element 5, coming into contact with the lower surface of the contact element 90, as is shown in Fig. 4a. The rotatable element 5 is thus fixed against further rotation and only the mechanical coding part 2 of the lock keeps rotating. By turning the key 4 to the initial position, it is possible to remove it out of the key channel, thereby releasing the pressure of the key 4 on the contact element 90 which turns back and its upper part 900 engages due to the action of the compression spring 92 through the blocking tow bar 91 into the radial recess 22 in the end element of the mechanical coding part 2 of the lock. In doing so, also the blocking tow bar 91 is inserted more deeply into the radial recess 50 in the rotatable element 5 and simultaneously during this further movement of the blocking tow bar 91 upwards pushes the bending 9120 of the lateral arm 912 to the adjacent lateral wall 9301 of the flat spacer cam 930, thereby turning the flat spacer cam 930 to the initial position, indicated in Fig. 1b. In this position, the blocking surface 9300 of the flat spacer cam 930 is again arranged opposite the lower end 9110 of the spacer pin 911 of the blocking tow bar 91 and thus blocks it again from being pushed in the downward direction. The lock is now locked.

    [0029] It is apparent from the above-mentioned that the blocking mechanism of the rotation of the mechanical coding part 2 of the lock and of the rotatable element 5 spontaneously returns to its blocking position solely due to the mechanical means, i.e., without the action of the rotary electric drive 93 and without consuming electric energy. Therefore, the rotary electric drive 93 rotates electrically only in one direction, i.e. during unlocking the lock.

    [0030] In the illustrated exemplary embodiment, the housing 1 of the lock is reinforced with at least one stirrup 12.

    [0031] It is obvious that the above-described solution can be used without any major adjustments and within the scope of the present invention also in other types of locks, especially in locks with spring-loaded pin tumblers in radial guide openings, etc. It is also evident that the illustrated rotary electric drive 93 in the bottom part 11 of the housing 1 may be replaced with another suitable type of drive, e.g. with a smaller rotary drive or a linear drive, etc., by which means a space is created in the lower part 11 of the housing 1, e.g., for a system of mechanical pin tumblers, etc.
