Abstract

An electronic locking cylinder comprises a housing (2) and a cylinder core (4) rotatably mounted in the housing about a rotation axis. The cylinder core comprises an external sector (44) configured to receive a key element (12) and an internal sector (46), separated from each other by a protection member (80). The internal sector comprises an authentication circuit and an actuator unit (6). An electrical interface (14) with the key element is provided to transfer energy to the authentication circuit and to the actuator unit and to exchange authentication data with the authentication circuit. The actuator unit comprises a locking member (8) which can be set in a blocking state and a release state. The actuator unit can be switched between an activatable state and a deactivated state. In the activatable state, the actuator unit is configured to be able to transfer the locking member from its blocking state to its release state. In the deactivated state, the actuator unit is configured to set the locking member into its blocking state. The electronic locking cylinder further comprises a mechanical transfer element (70) which is moved during the insertion movement of the key element from a first position to a second position. The actuator unit is in its activatable state when the mechanical transfer element is in its second position and the actuator unit controls the locking member to be transferred from its blocking state to its release state upon the exchange of the authentication data with the authentication circuit if the mechanical transfer element is in its second position. The actuator unit is in its deactivated state when the mechanical transfer element is in its first position. The electronic locking cylinder further comprises means (20) configured to force the mechanical transfer element into its first position by the pull-out movement of the key element. The means force the mechanical transfer element into its first position when the key element is pulled out. Consequently, the pull-out movement causes - via the mechanical transfer element - the actuator unit to be in the deactivated state. In this manner safety features of the electronic locking cylinder are improved.

Description

TECHNICAL FIELD

The present invention relates to an electronic lock. In particular, the invention relates to an electronic locking cylinder. The invention relates in particular to an electronic locking cylinder which comprises a cylinder core having an external sector and an internal sector, wherein the internal sector is separated from the external sector by a protection member.

BACKGROUND

Mechanical and electronic locking cylinders are known in the art, wherein electronic locking cylinders provide a plurality of advantages, e.g., flexibility in that keys and/or locking cylinders can be individually programmed. Electronic locking cylinders come in a variety designs, e.g., electronic locking cylinders with knobs for accommodating electronic parts and/or antennas are typically used with wireless electronic keys. There are also knobless electronic locking cylinders which are typically locked and unlocked by keys which are partly inserted in the locking cylinder body like a conventional mechanical key. Such keys contain additional electronic means, e.g. in form of an electronic circuit, for transmitting authentication data to the electronic locking cylinder.
Such a typical knobless electronic locking cylinder according to the prior art comprises a cylinder core rotatably mounted in a housing. The cylinder core often has an external sector and an internal sector, wherein the two sectors are separated from each other by a drilling protection member. To avoid manipulation, an actuator configured to control a locking member is typically provided within the internal sector, i.e., said actuator is protected by the drilling protection member. The actuator can switch the locking member from a release position to a blocking state and vice versa. In the blocking state, a rotation of the cylinder core is prevented and in the release state cylinder core is rotatable, i.e., the locking member does not prevent the rotation of the cylinder core. In order to control the electronic lock with an electronic key, the electronic locking cylinder further comprises an electrical interface to exchange authentication data between the electronic key, which is inserted into the cylinder core, and the actuator. Upon an exchange of proper authentication data and, additionally, a proper transmission of a mechanical force between the key and the actuator, the actuator is set into a state in which it is able to move the locking member from its blocking state into its release state.
An electronic key for operating a knobless electric lock cylinder typically has an extension pointing in the direction in which the key is to be inserted into the cylinder core, wherein the extension serves to transmit a mechanical force to the locking cylinder.
However, due to this mechanical interface with a key, some knobless electronic locking cylinders are susceptible to manipulating attempts aimed at fixing mechanical elements within the electronic locking cylinder in an open state.

SUMMARY

There is a need for an electronic locking cylinder having enhanced safety features. There is in particular a need for an electronic locking cylinder that provides enhanced safety against manipulation attempts aiming at fixing an actuator of an electronic locking cylinder in a state in which it is able to move a locking member of the electronic locking cylinder from a blocking state into a release state.
An electronic locking cylinder as recited in the independent claim is provided. The dependent claims define further preferred embodiments of the present invention.
According to the invention, an electronic locking cylinder is provided which comprises a housing and a cylinder core which is mounted in the housing so that it can be rotated relative to the housing about a rotation axis. The locking cylinder is not restricted to a specific type of cylinder and the present invention can be implemented in a plurality of different designs. For instance, the locking cylinder may be a profile cylinder (as illustrated in the figures), preferably a profile cylinder according to DIN 18252 / EN 1303. The cylinder may also be a Scandinavian oval cylinder, an American or Scandinavian round mortise cylinder or a Euro cylinder without being restricted to these examples.
The cylinder core is preferably configured to receive a key element. The key element can be inserted from an outside space into the cylinder core via an insertion movement into an inserted position, and the key element can be pulled out from the inserted position to the outside space via a pull-out movement.
Preferably, the cylinder core comprises an external sector configured to receive a key element, e.g., by providing an opening at the external sector, and an internal sector. The internal sector preferably comprises an authentication circuit and an actuator unit. The internal sector preferably is separated from the external sector by a protection member, e.g., a protection against drilling preferably made from hardened steel and/or metal ceramic inserts.
The external sector of the cylinder core comprises an opening through which the key element can be inserted from the outside space via an insertion movement into the inserted position and through which the key element can be pulled out from the inserted position to the outside space via a pull-out movement.
Preferably, the pull-out movement can only be carried out in a limited rotational range of the cylinder core. Preferably, the locking cylinder is configured such that the pull-out movement of the key element can only be carried out if the cylinder core is positioned within a limited rotational range with respect to the rotation axis.
Preferably, an electrical interface with the key element is provided to transfer energy to the authentication circuit and to the actuator unit and to exchange authentication data with the authentication circuit. Specifically, the electronic locking cylinder may further comprise an electrical interface which is configured to interact with the key element in order to transfer energy to the authentication circuit and to exchange authentication data with the authentication circuit.
The actuator unit may comprise a locking member which can be set in a blocking state and a release state, wherein in the blocking state a rotation of the cylinder core is prevented by the locking member and in the release state the locking member does not prevent the rotation of the cylinder core.
The actuator unit can be switched between an activatable state and a deactivated state, wherein in the activatable state, the actuator unit is configured to be able to transfer the locking member from its blocking state to its release state, and wherein in the deactivated state, the actuator unit is configured to set the locking member into its blocking state.
The electronic locking cylinder further comprises a mechanical transfer element. Preferably, the electronic locking cylinder is configured such that the mechanical transfer element is moved during the insertion movement of the key element from a first position to a second position, the actuator unit is in its activatable state when the mechanical transfer element is in its second position and the actuator unit controls the locking member to be transferred from its blocking state to its release state upon the exchange of the authentication data with the authentication circuit if the mechanical transfer element is in its second position. The configuration is further such that the actuator unit is in its deactivated state when the mechanical transfer element is in its first position.
The electronic locking cylinder further comprises means, e.g., in form of mechanical components, configured to force the mechanical transfer element into its first position by or upon the pull-out movement of the key element.
The means force the mechanical transfer element into its first position by the pull-out movement of the key element, i.e., when the key element is pulled out from its inserted position within the external sector of the cylinder core to the outside space. Consequently, the pull-out movement of the key element causes - via the mechanical transfer element - the actuator unit to be switched into its deactivated state.
In this way, unwanted manipulation of the electronic locking cylinder aimed at moving the locking member in its release state, when the key element is pulled out, is made more difficult. Accordingly, the safety of the electronic locking cylinder is enhanced.
The means configured to force the mechanical transfer element into its first position by or upon the pull-out movement of the key element are preferably configured such that they force the mechanical transfer element exclusively caused by the pull-out movement of the key element, i.e., without being supported by an external energy source, such as for example an electrical energy source. Preferably, the energy/force needed by the means to force the mechanical transfer element into its first position by or upon the pull-out movement of the key element is exclusively provided by the pull-out movement of the key element. In other words, the energy needed solely originates from the pull-out movement of the key element.
The mechanical transfer element may be mounted such that a movement of the mechanical transfer element, specifically a movement between the first position and the second position is at least predominantly rotational. This makes an unwanted manipulation of the electronic locking cylinder aiming at fixing the mechanical transfer element in its second position more difficult.
The mechanical transfer element may be supported by the protection member. The protection member may be e. g. a drilling protection member. The protection member may be arranged and configured to provide a seal between the external sector and the internal sector. The protection member may show a substantially circular cross-section perpendicular to the rotation axis.
The mechanical transfer element may comprise a first portion extending into the external sector of the cylinder core and a second portion extending into the internal sector of the cylinder core. The protection member may comprise a through-hole or a recess for supporting the mechanical transfer element. The through-hole or recess may comprise a main axis which is oriented parallel to the rotation axis of the cylinder core.
The mechanical transfer element may be essentially formed in a U-shape, wherein the two side pieces or limbs of the "U" are formed by the first portion and the second portion and the base line of the "U" connecting the limbs is formed by a middle portion of the mechanical transfer element which extends through the protection member, preferably in a direction parallel to the rotation axis. The middle portion may show a circular cross-section perpendicular to the rotation axis of the cylinder core. The middle portion of the mechanical transfer element may extend through the through-hole or recess of the protection member.
The mechanical transfer element may be mounted rotatable relative to a further rotation axis being oriented parallel to and having an offset relative to the rotation axis of the cylinder core. The mechanical transfer element can be arranged such that there is a distance between the mechanical transfer element and the rotation axis of the cylinder core, preferably a distance between the middle portion of the mechanical transfer element and the rotation axis of the cylinder core. In this way unwanted manipulation of the mechanical transfer element is made even more difficult.
The offset between the rotation axis of the cylinder core and the further rotation axis may be at least 10% of a maximum length of the opening of the external sector, measured perpendicular to the rotation axis, preferably at least 20%, preferably at least 30%, preferably at least 50%, preferably at least 60%.
The further rotation axis may be located outside the opening as seen in a projection along the rotation axis of the cylinder core if the cylinder core is positioned within the limited rotational range.
Preferably, the mechanical transfer element is made of an inflexible or rigid material. Preferably, the mechanical transfer element is configured such that a torque with respect to the further rotation axis acting on the first portion of the mechanical transfer element is directly transmitted via the middle portion to the second portion.
The electronic locking cylinder, particularly the means configured to force the mechanical transfer element into its first position by the pull-out movement of the key element may comprise a mechanical coupling element which is mounted to be movable between a first position and a second position, wherein the configuration is such that the mechanical transfer element is moved into its second position when the mechanical coupling element is moved from its first position into its second position, and the mechanical transfer element is moved, particularly inevitably or positive, into its first position when the mechanical coupling element is moved from its second position into its first position.
The mechanical coupling element allows a particularly suitable mechanical coupling between the insertion movement and the pull-out movement of the key on the one hand and the positioning of the mechanical transfer element into its first or second position on the other hand.
The mechanical coupling element may comprise a first area configured to interact with the key element during the insertion movement of the key element in order to move the mechanical coupling element from its first position into its second position.
The mechanical coupling element may further comprise a second area configured to interact with the key element during the pull-out movement of the key element in order to move the mechanical coupling element from its second position into its first position.
The configuration is preferably such that the mechanical coupling element is inevitably moved into its first position by the pull-out movement of the key element.
The mechanical coupling element may be mounted in the external sector to be pivotable between its first position and its second position. Preferably, the mechanical coupling element is mounted pivotable about a mechanical coupling element rotation axis which is oriented at least substantially perpendicular to the rotation axis of the cylinder core.
The configuration is preferably such that the mechanical coupling element can be moved into its first position exclusively when the cylinder core is in the limited rotational range.
The housing may comprise a recess configured to receive a portion of the mechanical coupling element if the mechanical coupling element is in its first position. In this way it can be achieved that a rotation of the cylinder core is prevented by an interaction between the portion of the mechanical coupling element and a wall segment of the recess, if the mechanical coupling element is in its first position. This can ensure that the key element can only be pulled out of the cylinder if the cylinder core is within a defined rotational range, for example within the limited rotational range.
The configuration is preferably such that if the mechanical coupling element is in its second position and the key element is inserted from the outside space into its inserted position, the mechanical coupling element is firstly moved by the key element into its first position and subsequently back into its second position.
In this case, the mechanical coupling element preferably comprises a surface segment which is designed to move the mechanical coupling element from its second position into its first position during a first period of the insertion movement of the key element. Preferably, during a second period of the insertion movement, subsequent to the first period, the mechanical coupling element is moved from its first position into its second position.
The electronic locking cylinder may be a knobless electronic cylinder.
The electronic locking cylinder may be configured to be operated without a battery.
The electronic locking cylinder may be a half cylinder or a double cylinder.
According to a further aspect of the invention, an electronic locking cylinder system is provided which comprises an electronic locking cylinder according to the present description and the key element.

DETAILED DESCRIPTION OF EMBODIMENTS

Embodiments of the invention will be described in detail with reference to the drawings.
Fig. 1 is a partial broken-away perspective view of a portion of an electronic locking cylinder 42 according to an embodiment. The electronic locking cylinder 42 comprises a housing 2 and a cylinder core 4 which is mounted in the housing 2 so that it can be rotated relative to the housing 2 about a rotation axis R1. The cylinder core 4 may comprise a lock bit 3 or may be torque-proof connected with a lock bit 3.
The cylinder core 4 comprises an external sector 44 configured to receive a key element 12 (note that only a portion of the key element is illustrated in Fig. 1) and an internal sector 46 comprising an authentication circuit and an actuator unit 6. The internal sector 46 is separated from the external sector 44 by a protection member 80. The protection member 80 may be arranged and configured to provide a seal, particularly a hermetical seal between the external sector 44 and the internal sector 46. The protection member 80 may be made of carbide. The protection member 80 may be a drilling protection member. The protection member 80 may be essentially plate shaped and oriented perpendicular to the rotation axis R1. The protection member 80 may be designed such that it covers at least 70%, preferably at last 80% of the cylinder core 4 as seen in a projection along the rotation axis R1.
The internal sector 46 may be configured as a hermetically protected sector, providing protection against attack and weather conditions. Accordingly, a modularity is achieved through the two sectors 44, 46.
The external sector 44 comprises an opening 10 through which the key element 12 can be inserted from an outside space A via an insertion movement into an inserted position. When the key element 12 is in the inserted position, it preferably exclusively engages the external sector 44, specifically, it preferably does not extend into or through the protection member 80 in a direction along the rotation axis R1.
The key element 12 can be pulled out through the opening 10 from the inserted position to the outside space A via a pull-out movement.
Both, the insertion movement and the pull-out movement of the key element 12 are preferably directed parallel to the rotation axis R1.
The configuration is preferably such that the pull-out movement can only be carried out if the cylinder core 4 is within a limited rotational range with respect to the rotation axis R1. For example, the limited rotational range may be less than 10°, preferably less than 5°, preferably less than 3°.
The electronic locking cylinder 42 may further comprise an electrical interface 14 configured to interact with the key element 12 in order to transfer energy to the authentication circuit and in order to exchange authentication data with the authentication circuit. The configuration is such that the exchange of the authentication data is a necessary condition for regularly opening the electronic locking cylinder with the key element 12.
The actuator unit 6 comprises a locking member 8 which can be set alternatively into a blocking state and into a release state. Fig. 1 illustrates a state in which the locking member 8 is in its blocking state. Fig. 2 illustrates a state of the electronic locking cylinder 42 in which the locking member 8 is in its release state. A rotation of the cylinder core 4 is prevented by the locking member 8 if the locking member 8 is in its blocking state. A rotation of the cylinder core 4 is not prevented by the locking member 8 if the locking member 8 is in its release state.
The housing 2 may comprise a locking member receiving recess 88 configured to receive a portion of the locking member 8 when the locking member 8 is in its blocking state, such that a rotation of the cylinder core 4 is prevented by an interaction of the portion of the locking member 8 with a wall section of the locking member receiving recess 88. Preferably, the design of the locking member 8 and the locking member receiving recess 88 is such that a rotation of the cylinder core 4 with respect to the rotation axis R1 is limited to a limited rotational range which may be less than 10°, preferably less than 5°, preferably less than 3°. This limited rotational range may constitute a clearance of the cylinder core 4 with respect to the locking member 8.
The actuator unit 6 can be switched between a deactivated state and an activatable state. The actuator unit 6 is configured to be able to transfer the locking member 8 from its blocking state to its release state when it is in the activatable state. The actuator unit 6 is configured to set the locking member 8 into its blocking state when it is in the deactivated state.
The electronic locking cylinder 42 further comprises a mechanical transfer element 70. The configuration is such that the mechanical transfer element 70 is moved during the insertion movement of the key element 12 from a first position, as exemplarily illustrated in Fig. 1 into a second position as exemplarily illustrated in Fig. 2 and further such that the mechanical transfer element 70 is moved during the pull-out movement of the key element 12 from its second position into its first position.
The configuration is further such that the actuator unit 6 is in its activatable state when the mechanical transfer element 70 is in its second position and such that the actuator unit 6 is in its deactivated state when the mechanical transfer element 70 is in its first position.
The electronic locking cylinder 42 preferably further comprises first coupling element(s) (not illustrated in the figures) arranged and configured to couple the mechanical transfer element 70 with the actuator unit 6 such that the actuator unit 6 is in its activatable state when the mechanical transfer element 70 is in its second position and such that the actuator unit 6 is in its deactivated state when the mechanical transfer element 70 is in its first position.
The configuration is further such that the actuator unit 6 controls the locking member 8 to be transferred from its blocking state into its release state upon the exchange of the authentication data with the authentication circuit if the mechanical transfer element 70 is in its second position.
The electronic locking cylinder 42 further comprises means configured to force the mechanical transfer element 70 into its first position by the pull-out movement of the key element 12.
Thus, when the key element 12 has been pulled out, the mechanical transfer element 70 is in its first position and consequently, the actuator unit 6 is in its deactivated state and the locking member 8 is in its blocking state.
The mechanical transfer element 70 is preferably mounted such that a movement of the mechanical transfer element 70 is at least predominantly rotational, specifically the movement of the mechanical transfer element 70 from its first position into its second position and a further movement vice versa are at least predominantly rotational.
The mechanical transfer element 70 is preferably supported by the protection member 80. The protection member 80 may comprise a recess 82 or a through-hole (see Fig. 2) configured to support the mechanical transfer element 70. The recess 82 or through-hole may comprise a main axis that is oriented parallel to the rotation axis R1. The protection member 80 may comprise, as seen along the rotation axis R1, a circular shape except for the recess 82 or through-hole. The center of the circular shape may coincide with the rotation axis R1. Preferably, the recess 82 or through-hole is formed at an edge region of the protection member 80.
The mechanical transfer element 70 is preferably mounted such that it can be rotated relative to a further rotation axis R2 which is oriented parallel to the rotation axis R1 of the cylinder core 4, wherein the further rotation axis R2 has an offset δ with respect to the rotation axis R1 of the cylinder core 4.
Preferably, the design of the protection member 80 is such that the recess 82 or through-hole does not include the rotation axis R1 as seen in a projection along the rotation axis R1. Preferably, a distance between the recess 82 or the through-hole and the rotation axis R1, as seen in the projection, is at least 30%, preferably at least 40% of a maximum length e (see Fig. 2) of the opening 10 measured perpendicular to the rotation axis R1.
The electronic locking cylinder 42, particularly the means configured to force the mechanical transfer element into its first position by the pull-out movement of the key element may further comprise a mechanical coupling element 20 which is mounted to be movable between a first position and a second position. The configuration may be such that the mechanical transfer element 70 is moved into its second position when the mechanical coupling element 20 is moved from its first position into its second position, and the mechanical transfer element 70 is moved into its first position when the mechanical coupling element 20 is moved from its second position into its first position. To this end, the electronic locking cylinder preferably further comprises second coupling element 72 arranged and configured to couple the mechanical coupling element 20 with the mechanical transfer element 70 correspondingly. An example of a preferred second coupling means is shown in the figures without being restricted to said design.
Fig. 3 is an enlarged section of Fig. 1 showing an area around the mechanical coupling element 20. The mechanical coupling element 20 may comprise a first area 22 configured to interact with the key element 12 during the insertion movement of the key element 12 in order to move the mechanical coupling element 20 from its first position into its second position. The mechanical coupling element 20 may further comprise a second area 24 configured to interact with the key element 12 during the pull-out movement of the key element 12 in order to move the mechanical coupling element 20 from its second position into its first position.
Correspondingly, the key element 12 may comprise a first surface portion 11 configured to interact with the first area 22 of the of the mechanical coupling element 20 during the insertion movement and a second surface portion 13 configured to interact with the second area 24 of the of the mechanical coupling element 20 during the pull-out movement.
The mechanical coupling element 20 may be mounted in the external sector 44 to be pivotable between its first position and its second position. Preferably, the mechanical coupling element 20 is mounted pivotable about a mechanical coupling element rotation axis R3 (see Figures 2 and 3) which is oriented at least substantially perpendicular to the rotation axis R1 of the cylinder core 4.
The configuration may be such that the mechanical coupling element 20 can be moved into its first position exclusively when the cylinder core 4 is in the limited rotational range.
The housing 2 may comprise a mechanical coupling element receiving recess 18 configured to receive a portion of the mechanical coupling element 20 if the mechanical coupling element 20 is in its first position. Preferably, the design of the mechanical coupling element 20 and the mechanical coupling element receiving recess 18 is such that a rotation of the cylinder core 4 with respect to the rotation axis R1 is limited to a further limited rotational range which may be less than 10°, preferably less than 5°, preferably less than 3°. This further limited rotational range may constitute a clearance of the cylinder core 4 with respect to the mechanical coupling element 20.
Preferably, the clearance of the cylinder core 4 with respect to the mechanical coupling element 20 is smaller than the clearance of the cylinder core 4 with respect to the locking member 8. In this way the risk of the locking member 8 being trapped is reduced.
The configuration may be such that if the mechanical coupling element 20 is in its second position and the key element 12 is being inserted from the outside space A into its inserted position, the mechanical coupling element 20 is firstly moved by the key element 12 into its first position and subsequently back into its second position. To this end, the mechanical coupling element 20 may comprises a surface segment 26 (see Figures 2 and 3) which is designed to move the mechanical coupling element 20, preferably by interaction with the first surface portion 11 of the key element 12, from its second position into its first position during a first period of the insertion movement of the key element 12. During a subsequent second period of the insertion movement, the mechanical coupling element 20 is moved into its second position.
While embodiments have been described with reference to the drawings, alterations and modifications may be implemented in other embodiments.
