Patent Description:
Some electromechanical lock cylinders comprise a cylinder housing, a locking member rotatably arranged in the cylinder housing, a rotatable knob and an electromechanical coupling device for selectively coupling the knob with the locking member. When a user has been authorized, the coupling device couples the knob and the locking member and the lock can be opened by manually rotating the knob.

Some of these lock cylinders comprise a battery for powering the coupling device and electronics, such as credential evaluation electronics, arranged in the knob. The battery and the electronics are typically arranged in the rotatable knob in order to prevent cables from getting entangled or disconnected. When the knob rotates, the battery, the electronics and the coupling device rotate. This leads to a product which relies on a coupling device housing to absorb most forces during use. Moreover, if the knob is smashed away by a criminal in a so-called brute force attack, electronics inside the knob may be exposed for unauthorized tampering.

<CIT> discloses an electromechanical lock cylinder comprising a cylinder housing, a knob, a clutch and an electromotor working as a generator.

<CIT> discloses an electromechanical lock cylinder comprising a coupling unit which couples a handle to a locking member using an electromechanical clutch. Rotating wire electrical contacts are employed to transmit signals between rotating and non-rotating parts.

<CIT> discloses an electromechanical lock cylinder comprising a motor for direct actuation of a lock member. Rotating wire electrical contacts and alternatively inductive wireless power transmission are employed between the rotating handle and the cylinder for energy transfer.

One object of the present invention is to provide an actuating device for a lock device, which actuating device is secure.

A further object of the present invention is to provide an actuating device for a lock device, which actuating device has a less complicated design and/or operation.

A still further object of the present invention is to provide an actuating device for a lock device, which actuating device has a reliable design and/or operation.

A still further object of the present invention is to provide an actuating device for a lock device, which actuating device has a cost effective design and/or operation.

A still further object of the present invention is to provide an actuating device for a lock device, which actuating device solves several or all of the foregoing objects in combination.

A still further object of the present invention is to provide a lock device comprising an actuating device, which lock device solves one, several or all of the foregoing objects.

According to the invention, there is provided an actuating device for a lock device, the actuating device comprising a stationary structure; an actuating element rotatable relative to the stationary structure; an electric power source; a spindle arranged to be rotated by rotation of the actuating element; a locking member movable between a locked position and an unlocked position; an electromechanical transfer device arranged in the spindle, the transfer device being configured to adopt a locked state, in which the locking member cannot be moved from the locked position to the unlocked position by rotation of the actuating element, and an unlocked state in which the locking member can be moved from the locked position to the unlocked position by rotation of the actuating element; a receiver device fixed with respect to the spindle, the receiver device being electrically connected to the transfer device; and a transmitter device fixed with respect to the stationary structure and arranged to be electrically powered by the power source, the transmitter device being configured to wirelessly transmit power to the receiver device.

The stationary transmitter device is thus arranged to wirelessly transfer electric power to the rotatable receiver device. Moreover, since the spindle is arranged to be rotated by rotation of the actuating element, mechanical energy can be transferred from the actuating element to the spindle by manual rotation of the actuating element.

By arranging the transfer device in the spindle, unauthorized access to the transfer device is made more difficult. Consequently, the actuating device is made more secure.

The actuating element may be rotatable about an actuation axis. The actuating element may be a knob.

The spindle may be arranged to rotate in common with the actuating element. Alternatively, or in addition, the spindle may be arranged to rotate about the actuation axis. Alternatively, or in addition, the actuating device may further comprise a transmission arranged to transmit a rotation of the actuating element to a rotation of the spindle. The transmission may comprise a gear train. The spindle may comprise a plug.

The power source may be fixed with respect to the stationary structure. Electric cables may be provided between the power source and the transmitter device. The locking member may be rotatable between the locked position and the unlocked position.

The transfer device may be arranged entirely within the stationary structure. Alternatively, or in addition, the transfer device may be fixed to the spindle. In this way, the transfer device rotates in common with the spindle.

The transfer device may comprise a coupling device configured to couple the spindle to the locking member when adopting the locked state, and configured to decouple the spindle from the locking member when adopting the unlocked state. In this case, the spindle and the locking member may rotate in common when the coupling device adopts the locked state. When the coupling device adopts the unlocked state, the actuating element can be rotated but this rotation is not transferred to any movement of the locking member.

Alternatively, the transfer device may comprise a blocking device configured to block rotation of the spindle when adopting the locked state, and configured to unblock rotation of the spindle when adopting the unlocked state. In this case, the spindle and the locking member may be fixedly connected or integrally formed. When the blocking device adopts the locked state, the actuating element cannot be rotated. When the blocking device adopts the unlocked state, rotation of the actuating element is transferred to a common rotation of the spindle and the locking member.

The power source may comprise an electromagnetic generator arranged to be driven by rotation of the actuating element to thereby generate electric energy. The actuating device comprising the generator is an energy harvesting actuating device. The generator may comprise a stator and a rotor, where the rotor is arranged to be rotationally driven relative to the stator by rotation of the actuating element to thereby generate electric energy.

The actuation device may for example comprise power management electronics configured to manage the energy harvesting and to control the supply of power to the transfer device. To this end, the power management electronics may comprise energy harvesting electronics, such as diodes for rectifying the voltage from the electric generator and a passive non-chemical electric energy storage device, such as a capacitor. Thereby, electric energy can be harvested from rotation of the actuating element in either direction about the actuation axis. The electric energy storage device may or may not comprise a battery.

The electric energy storage device may be fixed with respect to the stationary structure, i.e. provided on the "outside". Alternatively, the electric energy storage device may be fixed with respect to the spindle, i.e. provided on the "inside". In the former case, harvested electric energy may initially be bulked in the electric energy storage device prior to transmission from the transmitter device to the receiver device. In the latter case, harvested electric energy may be directly transmitted from the transmitter device to the receiver device and then stored in the electric energy storage device on the "inside".

Alternatively, or in addition, the power source may comprise a battery instead of a generator.

The transmitter device may be configured to inductively transmit power to the receiver device. The transmitter device may comprise an electromagnetic wave transmission coil and the receiver device may comprise an electromagnetic wave receiving coil. The electromagnetic wave transmission coil and the electromagnetic wave receiving coil may be near field communication (NFC) transmission coils. Each of the transmitter device and the receiver device may comprise a resonant capacitance. Electric power can be transferred from the transmitter device to the receiver device through magnetic field resonance between the electromagnetic wave transmission coil and the electromagnetic wave receiving coil. The transmitter device may further comprise an amplifier unit having a switching circuit. The receiver device may further comprise a power reception unit having a rectifying and smoothing circuit. The electromagnetic wave transmission coil and the electromagnetic wave receiving coil together form a transformer. An alternating current through the electromagnetic wave transmission coil creates an oscillating magnetic field by Ampere's law. The magnetic field passes through the electromagnetic wave receiving coil where it induces an alternating electromotive force, EMF, (voltage) by Faraday's law of induction, which creates an alternating current in the electromagnetic wave receiving coil.

The spindle may be rotatable about a rotation axis. In this case, each of the transmitter device and the receiver device may be substantially centered, or centered, with respect to the rotation axis. In this way, the transmitter device and the receiver device are always coaxially arranged. Moreover, the transmitter device and the receiver device may be arranged at a fixed distance. In these ways, energy transfer efficiency between the transmitter device and the receiver device can be maximized. The rotation axis may be concentric with the actuation axis.

The spindle may be arranged inside the stationary structure. In this way, the stationary structure protects the transfer device from unauthorized tampering should the actuating element be removed in a brute force attack.

The actuating device may further comprise a connection member functionally connected between the actuating element and the spindle. In this case, the connection member may be arranged to release upon removal of the actuating element. With functionally connected is meant that a rotation of the actuating element transmitted to a rotation of the spindle at least partly by the connection member. In case the actuating device is subjected to a brute force attack such that the actuating element is removed, the release of the connection member makes it difficult to rotate the spindle. Moreover, the force from the brute force attack is not transmitted to the transfer device once the connection member has released. In this way, the security of the actuating device is further improved.

The transmitter device may comprise a transmitter device opening and the receiver device may comprise a receiver device opening. In this case, the connection member may pass through the transmitter device opening and the receiver device opening.

The connection member may be connected to the spindle by means of a shape lock. A first end of the connection member may be connected to the spindle by means of the shape lock. A second end of the connection member may be fixed to the actuating element, such as integrally formed with the actuating element. Alternatively, the second end of the connection member may be fixed to a part of a transmission of the actuating device.

The connection member may comprise a polygonal cross-sectional profile and the spindle may comprise an opening having a corresponding polygonal cross-sectional profile. One example of such polygonal cross-sectional profile is a square shape.

The connection member may be a bar. Alternatively, or in addition, the connection member may be made of metal.

The transmitter device may be configured to wirelessly transmit a signal to the receiver device. Alternatively, or in addition, the receiver device may be configured to wirelessly transmit a signal to the transmitter device. In these ways, data can be wirelessly transmitted between the receiver device and the transmitter device.

The actuating device may further comprise credential evaluation electronics provided in the spindle and credential reading electronics. In this case, the credential evaluation electronics may be configured to evaluate an access signal from the credential reading electronics and to issue an authorization signal to the transfer device to adopt the unlocked state upon a granted evaluation of the access signal. The access signal may contain credential data associated with a user.

The credential reading electronics may comprise a receiving unit, such as an antenna, for receiving an input signal, and a reading unit. The credential reading electronics may be configured to send the access signal to the credential evaluation electronics. The credential evaluation electronics may be configured to determine whether or not authorization should be granted based on the access signal. If access is granted, e.g. if a valid credential is presented, the credential evaluation electronics may issue the authorization signal. If access is not granted, e.g. if an invalid credential is presented or if no credential is presented, the credential evaluation electronics may not issue the authorization signal.

The power management electronics and the credential reading electronics may be arranged inside the actuating element and the credential evaluation electronics may be arranged inside the spindle. The credential reading electronics may be arranged to communicate wirelessly with an external device, such as a mobile phone. The wireless communication may for example be carried out by means of BLE (Bluetooth Low Energy) or RFID (Radio Frequency Identification). As an alternative to wireless communication, a user may input a code to the credential reading electronics, for example via a keypad. If an authorization request is denied, the transfer device is not switched, i.e. remains in the locked state.

By arranging the credential evaluation electronics in the spindle, unauthorized access to the credential evaluation electronics is made more difficult. The credential evaluation electronics is thus arranged deep inside the actuating device. Consequently, the actuating device is made more secure.

The actuating device may further comprise a feedback indicator. The actuating device may be configured to issue a feedback indication to the user by means of the feedback indicator based on an outcome of the evaluation of the access signal. Examples of feedback indicators are a loud speaker for issuing an audible indication, a light source for issuing a visible indication and a vibration device for issuing a tactile indication. The feedback indication may be of a first type upon a granted authorization of the access signal, and of a second type, different from the first type, upon a denied authorization of the access signal.

In case the actuating device comprises the feedback indicator, the receiver device may be configured to wirelessly transmit a feedback signal to the transmitter device. The feedback signal may be issued by the credential evaluation electronics.

The credential reading electronics may be fixed with respect to the stationary structure. In this case, the transmitter device may be configured to wirelessly, such as inductively, transmit the access signal to the receiver device. Alternatively, the credential reading electronics may be fixed with respect to the spindle, e.g. arranged in the spindle.

The power source may be fixed with respect to the stationary structure.

According to one aspect, there is provided a lock device comprising an actuating device according to the present invention.

The lock device may further comprise a cylinder housing. The locking member may be rotatably arranged within the cylinder housing.

The lock device may further comprise a driver. In this case, movement of the locking member from the locked position to the unlocked position may cause the driver to move from a driver locked position to a driver unlocked position. Conversely, movement of the locking member from the unlocked position to the locked position may cause the driver to move from the driver unlocked position to the driver locked position.

Further details, advantages and aspects of the present invention will become apparent from the following description taken in conjunction with the drawings, wherein:.

In the following, an actuating device for a lock device, and a lock device comprising an actuating device, will be described. The same or similar reference numerals will be used to denote the same or similar structural features.

<FIG> schematically represents a side view of a lock device <NUM>. The lock device <NUM> comprises an actuating device <NUM>. The lock device <NUM> of this specific example further comprises a first cylinder half <NUM>, a second cylinder half <NUM> and a driver <NUM>. The first cylinder half <NUM> and the second cylinder half <NUM> form one example of a cylinder housing. The driver <NUM> can actuate a bolt (not shown) of the lock device <NUM>.

<FIG> schematically represents an exploded perspective view of the actuating device <NUM>. The actuating device <NUM> comprises a stationary structure <NUM>, an actuating element <NUM>, an electromagnetic generator <NUM>, a spindle <NUM>, a locking member <NUM> and an electromechanical coupling device <NUM>. The actuating element <NUM> of this example is a knob.

The generator <NUM> is one example of an electric power source according to the present invention. The coupling device <NUM> is one example of an electromechanical transfer device according to the present invention. The coupling device <NUM> of this example comprises an actuator having an actuator pin (not shown).

The actuating device <NUM> further comprises a transmitter device <NUM> and a receiver device <NUM>. The transmitter device <NUM> comprises a transmitter device opening <NUM>. The receiver device <NUM> comprises a receiver device opening <NUM>.

The stationary structure <NUM> of this specific example comprises a body <NUM> and a through hole <NUM>. The through hole <NUM> extends through the body <NUM>.

The actuating device <NUM> of this specific example further comprises a first gear wheel <NUM> and a second gear wheel <NUM>. The first gear wheel <NUM> meshes with the second gear wheel <NUM>. The first gear wheel <NUM> comprises a square through hole <NUM>.

The actuating device <NUM> of this specific example further comprises credential reading electronics <NUM> and power management electronics <NUM>. The credential reading electronics <NUM> comprises a receiving unit (not shown), such as an antenna, for receiving an input signal, and a reading unit (not shown). The credential reading electronics <NUM> is arranged to communicate wirelessly with an external device, such as a mobile phone, for example by means of BLE.

The actuating device <NUM> further comprises a feedback indicator <NUM>. The feedback indicator <NUM> is configured to issue a feedback indication to a user. The feedback indicator <NUM> may for example be a loud speaker, a light source or a vibration device.

The actuating device <NUM> of this specific example further comprises a connection member <NUM>. The connection member <NUM> of this example is a bar integrally formed with the actuating element <NUM>. The connection member <NUM> protrudes distally from an end <NUM> of the actuating element <NUM> into the interior of the actuating element <NUM>. As used herein, a distal direction is a direction away from the user (e.g. towards the locking member <NUM>) and a proximal direction is a direction towards the user.

<FIG> schematically represents a perspective cross-sectional view of the actuating device <NUM>, and <FIG> schematically represents a cross-sectional side view of the actuating device <NUM>. With collective reference to <FIG> and <FIG>, the spindle <NUM> is arranged inside the body <NUM> of the stationary structure <NUM>. The stationary structure <NUM> may be bolted to a lock case (not shown) of the lock device <NUM>. The generator <NUM> is fixed to the stationary structure <NUM>.

The connection member <NUM> engages the first gear wheel <NUM> and the spindle <NUM>. Moreover, the connection member <NUM> passes through the transmitter device opening <NUM> and the receiver device opening <NUM>. The connection member <NUM> of this example comprises a square cross-sectional profile. The square cross-sectional profile of the connection member <NUM> engages the square through hole <NUM> of the first gear wheel <NUM>. The square cross-sectional profile of the connection member <NUM> further engages the spindle <NUM>. To this end, the spindle <NUM> comprises a proximal opening in which an end of the connection member <NUM> is received. The connection member <NUM> engages the spindle <NUM> by means of a shape lock <NUM>. Due to the shape lock <NUM>, rotation of the connection member <NUM> is transferred to a rotation of the spindle <NUM>. However, the connection member <NUM> can be retracted proximally away from the spindle <NUM>. One or more bearings (not shown) are provided between the stationary structure <NUM> and the actuating element <NUM>.

The coupling device <NUM> is arranged in and fixed to the spindle <NUM>. The stationary structure <NUM> thereby protects the coupling device <NUM> from unauthorized tampering. The spindle <NUM> is arranged to be rotated by manual rotation of the actuating element <NUM> about an actuation axis <NUM>.

The locking member <NUM> comprises a recess <NUM> for receiving the actuator pin of the coupling device <NUM>. The recess <NUM> faces in the proximal direction.

The locking member <NUM> is rotatable between a locked position <NUM> and an unlocked position. In <FIG> and <FIG>, the locking member <NUM> is in the locked position <NUM>. The locking member <NUM> is rotatably arranged within the cylinder housing (see <FIG>).

The coupling device <NUM> is configured to adopt a locked state <NUM> and an unlocked state. In <FIG> and <FIG>, the coupling device <NUM> is in the locked state <NUM>. In the locked state <NUM> of the coupling device <NUM>, the spindle <NUM> can be rotated by means of manual rotation of the actuating element <NUM>, but the rotation of the spindle <NUM> is not transmitted to a rotation of the locking member <NUM> by means of the coupling device <NUM>. In the unlocked state of the coupling device <NUM>, the spindle <NUM> is coupled to the locking member <NUM> by means of the coupling device <NUM>. The spindle <NUM> and the locking member <NUM> thereby rotate in common and the locking member <NUM> can be rotated from the locked position <NUM> to the unlocked position by manual rotation of the actuating element <NUM>. When the transfer device is constituted by the coupling device <NUM>, the locked state <NUM> and the unlocked state are thus constituted by an uncoupled state and a coupled state, respectively.

The receiver device <NUM> is fixed to the spindle <NUM>. The receiver device <NUM> and the spindle <NUM> thereby rotate in common. The receiver device <NUM> is electrically connected to the coupling device <NUM>. The transmitter device <NUM> is fixed to the stationary structure <NUM>. The transmitter device <NUM> is electrically powered by the generator <NUM>.

In this specific example, rotation of the actuating element <NUM> about the actuation axis <NUM> causes the first gear wheel <NUM> to rotate by means of the engagement between the connection member <NUM> and the first gear wheel <NUM>. The rotation of the first gear wheel <NUM> is transmitted to a rotation of the second gear wheel <NUM> by means of the meshing engagement therebetween. Rotation of the second gear wheel <NUM> drives a rotor (not shown) relative to a stator (not shown) of the generator <NUM> to thereby generate electric energy. The generator <NUM> is thus arranged to be driven by manual rotation of the actuating element <NUM> to harvest electric energy.

Moreover, in this specific example, rotation of the actuating element <NUM> about the actuation axis <NUM> causes the spindle <NUM> to rotate due to the engagement between the connection member <NUM> and the spindle <NUM> by means of the shape lock <NUM>. This is one of many realizations of arranging the spindle <NUM> to rotate by means of rotation of the actuating element <NUM>. The connection member <NUM> is thus functionally connected between the actuating element <NUM> and the spindle <NUM>.

The power management electronics <NUM> is configured to manage the energy harvesting and to control the supply of power to the coupling device <NUM>. To this end, the power management electronics <NUM> comprises energy harvesting electronics (not shown), such as diodes for rectifying the voltage from the generator <NUM> and a passive non-chemical electric energy storage device (not shown), such as a capacitor. Thereby, electric energy can be harvested from rotation of the actuating element <NUM> in either direction about the actuation axis <NUM>. In this example, the power management electronics <NUM> is fixed with respect to the stationary structure <NUM>.

When the actuating element <NUM> is manually rotated relative to the stationary structure <NUM> about the actuation axis <NUM>, the receiver device <NUM> rotates but the transmitter device <NUM> is stationary. The transmitter device <NUM> and the receiver device <NUM> are arranged at a fixed distance. The transmitter device <NUM> and the receiver device <NUM> are separated by an air gap <NUM>.

The transmitter device <NUM> is configured to wirelessly and inductively transmit power and signals to the receiver device <NUM>. To this end, the transmitter device <NUM> comprises an electromagnetic wave transmission coil and the receiver device <NUM> comprises an electromagnetic wave receiving coil. The receiver device <NUM> is also configured to wirelessly and inductively transmit signals to the transmitter device <NUM>. The transmission coil and the receiving coil are concentric with respect to a rotation axis of the spindle <NUM>. In this non-limiting example, the rotation axis of the spindle <NUM> is concentric with the actuation axis <NUM>.

The actuating device <NUM> further comprises credential evaluation electronics <NUM>. The credential evaluation electronics <NUM> is arranged in the spindle <NUM>. Unauthorized access to the credential evaluation electronics <NUM> is thereby made more difficult. The credential reading electronics <NUM> is arranged on the "outside", i.e. fixed with respect to the stationary structure <NUM>. In this example, the power management electronics <NUM> and the credential reading electronics <NUM> are arranged inside the actuating element <NUM>, but outside the spindle <NUM>, while the credential evaluation electronics <NUM> is arranged inside the spindle <NUM>.

The credential reading electronics <NUM> is configured to send an access signal <NUM> to the credential evaluation electronics <NUM>. The access signal <NUM> contains credential data associated with a user. As shown in <FIG> and <FIG>, the access signal <NUM> is transmitted wirelessly from the transmitter device <NUM> to the receiver device <NUM>. The credential evaluation electronics <NUM> is configured to evaluate the access signal <NUM>. In addition to authorization, the credential evaluation electronics <NUM> may be configured to authenticate the access signal <NUM>, i.e. to determine an authenticity of the user based on the access signal <NUM>.

If access is denied, i.e. if the access signal <NUM> contains an invalid credential or no credential, the credential evaluation electronics <NUM> sends a denied feedback signal to the feedback indicator <NUM>. In response to the denied feedback signal, the feedback indicator <NUM> issues a denied feedback indication, e.g. a sound of a first type. The denied feedback signal is wirelessly transmitted from the receiver device <NUM> to the transmitter device <NUM>.

If access is granted, i.e. if the access signal <NUM> contains a valid credential, the credential evaluation electronics <NUM> sends an authorization signal <NUM> to the coupling device <NUM>. In response to the authorization signal <NUM>, the coupling device <NUM> moves from the locked state <NUM> to the unlocked state. Moreover, the credential evaluation electronics <NUM> sends a granted feedback signal to the feedback indicator <NUM>. In response to the granted feedback signal, the feedback indicator <NUM> issues a granted feedback indication, e.g. a sound of a second type, different from the first type. The granted feedback signal is wirelessly transmitted from the receiver device <NUM> to the transmitter device <NUM>.

<FIG> schematically represents a cross-sectional side view of the actuating device <NUM> when the coupling device <NUM> has adopted the unlocked state <NUM>. In <FIG>, the actuator pin <NUM> of the coupling device <NUM> can be seen. In the unlocked state <NUM>, the actuator pin <NUM> is driven to protrude to engage the recess <NUM> of the locking member <NUM>. When the coupling device <NUM> has adopted the unlocked state <NUM>, manual rotation of the actuating element <NUM> is transmitted to a rotation of the locking member <NUM> from the locked position <NUM> to the unlocked position. Rotation of the locking member <NUM> from the locked position <NUM> to the unlocked position causes the driver <NUM> to move from a driver locked position to a driver unlocked position to open the lock device <NUM>.

In case the actuating device <NUM> is subjected to a brute force attack, for example if the actuating element <NUM> is smashed by a hammer, removal of the actuating element <NUM> will cause the connection member <NUM> to fall out from the shape lock <NUM>. In this way, generation of electric energy and rotation of the spindle <NUM> is made difficult. Moreover, the credential evaluation electronics <NUM> is not exposed even if the actuating element <NUM> is removed. <FIG> schematically represents a cross-sectional side view of a further example of an actuating device <NUM>. Mainly differences with respect to <FIG> will be described. Instead of the generator <NUM>, the actuating device <NUM> in <FIG> comprises a battery <NUM>. Moreover, instead of the coupling device <NUM>, the actuating device <NUM> comprises a blocking device <NUM>. The battery <NUM> and the blocking device <NUM> are further examples of a power source and a transfer device, respectively, according to the present invention.

In <FIG>, the locking member <NUM> is fixed to the spindle <NUM>. The actuator pin <NUM> is arranged to selectively engage a recess <NUM> in the stationary structure <NUM>. In <FIG>, the actuator pin <NUM> engages the recess <NUM> and the blocking device <NUM> thereby adopts the locked state <NUM>. When the blocking device <NUM> adopts the locked state <NUM>, the spindle <NUM> cannot be rotated. Consequently, also the actuating element <NUM> cannot be rotated.

If access is granted, i.e. if the access signal <NUM> contains a valid credential, the credential evaluation electronics <NUM> sends an authorization signal <NUM> to the blocking device <NUM>. In response to the authorization signal <NUM>, the blocking device <NUM> moves from the locked state <NUM> to the unlocked state <NUM>. Moreover, the credential evaluation electronics <NUM> sends a granted feedback signal to the feedback indicator <NUM>. In response to the granted feedback signal, the feedback indicator <NUM> issues a granted feedback indication, e.g. a sound. The granted feedback signal is wirelessly transmitted from the receiver device <NUM> to the transmitter device <NUM>.

<FIG> schematically represents a cross-sectional side view of the actuating device <NUM> in <FIG> when the blocking device <NUM> adopts the unlocked state <NUM>. In the unlocked state <NUM>, the actuator pin <NUM> is retracted out from the recess <NUM> and rotation of the spindle <NUM> is consequently unblocked. The spindle <NUM> and the locking member <NUM> can thereby be rotated in common by manual rotation of the actuating element <NUM>. When the transfer device is constituted by the blocking device <NUM>, the locked state <NUM> and the unlocked state <NUM> are thus constituted by a blocked state and an unblocked state, respectively. <FIG> schematically represents a cross-sectional side view of the actuating device <NUM> in <FIG> and <FIG> when the locking member <NUM> is in the unlocked position <NUM>.
