Technical Field
The invention relates to a lock with an alarm function for a two-wheeled vehicle, having a lock body and having a securing ring which is movable relative to the lock body between a securing position for securing the two-wheeled vehicle and an open position for releasing the two-wheeled vehicle, wherein the lock body has a locking mechanism to selectively lock the securing ring to the lock body in the securing position, and wherein the lock body further comprises an alarm device for outputting an alarm signal.
Background
For example, such a lock can be configured as a U-ring lock with a rigid, substantially U-shaped securing ring having a plurality of connecting rods pivotably connected to one another or as a folding lock with a connecting rod as securing ring. A two-wheel vehicle lock of the type described can also be configured as a so-called frame lock, in which a rotatable ring or a pivot ring is engaged between spokes of one of the wheels of the bicycle. In addition, such a lock may be configured as a brake disc lock, for example, wherein the retaining ring engages into a vent opening of a brake disc of a motorcycle or scooter. The securing ring may also be flexible, for example in the form of a chain or cable, which may be selectively locked to the lock body.
Locks of the type described are used, for example, to secure a two-wheeled vehicle to a bicycle stand, a lamp post or another stationary object, or to secure a two-wheeled vehicle against unauthorized riding. When the retaining ring is unlocked, the retaining ring may be moved to an open position where the retaining ring is released at one end or completely from the lock body. Starting from the open position, the securing ring can be guided, for example, around a frame part of the two-wheeled vehicle and a bicycle stand, a lamp post or the like, or the securing ring can be guided only by moving parts of the two-wheeled vehicle (for example, a rim, a brake disc). The retainer ring can then be (fully) closed and locked at the lock body, thereby securing the two-wheeled vehicle to prevent unauthorized removal or unauthorized riding. Unlocking the securing ring may be achieved by an authorized user actuating the locking mechanism of the lock by means of an associated key or another identification means.
The time required for unauthorized opening of the lock is an important aspect in the case of an attempt to manipulate a lock of a given type in order to steal a two-wheeled vehicle secured by the lock. The less time available to a thief, the more difficult it is to successfully maneuver an attempt. It is therefore conceivable to equip the lock with an alarm device which outputs an acoustic and/or optical alarm signal as soon as a manipulation attempt is detected, for example by determining a change in position or vibration during a monitoring operation. However, in practice, it is difficult for an authorized user to comfortably operate such an alarm device, particularly with respect to arming of the alarm device (hereinafter referred to as "activation" of the alarm device). For example, a vibration sensitive warning device may not trigger an output warning signal during transportation of the lock, and may not need to be activated each time the two-wheeled vehicle is locked (e.g., the two-wheeled vehicle is secured to a bicycle frame of a motor vehicle).
Therefore, an object of the present invention is to provide a two-wheeled vehicle lock with an alarm function, which enables comfortable and reliable operation of an alarm device.
Disclosure of Invention
This object is achieved by a two-wheeled vehicle lock comprising an alarm function having the features of claim 1, in particular the locking mechanism being selectively movable to an unlocked position, a locked position or an alarm activated position, wherein in the unlocked position the securing ring is released for movement to an open position, wherein in the locked position the securing ring in the secured position is locked at the lock body, and wherein the alarm device is activated or activatable by setting the locking mechanism to the alarm activated position.
In addition to the unlocked and locked positions of the locking mechanism, the locking mechanism may be moved, at least temporarily, to an alarm activated position. The alarm device of the two-wheeled vehicle lock can be activated as long as the lock mechanism is in the alarm activated position. It can also be provided that the alarm device is activated by temporarily moving the locking mechanism to an alarm activation position, wherein the alarm device can remain activated even if the locking mechanism is automatically moved to a different position. As described below, the alarm activated position may form another (i.e., second) locked position relative to the locking mechanism.
At least the following facts can be utilized:
in any case, the actuation of the locking mechanism of the two-wheeled vehicle lock, in particular for unlocking or locking, by an authorized user is provided, for example, by means of an associated key, electronic identification means, transmission code or a combination thereof. The authorized user may not only select the locked or unlocked state of the locking mechanism by appropriate actuation of the locking mechanism, i.e. by moving the locking mechanism to the alarm enabled state, but may also determine whether the alarm device should become enabled or be enabled or not. In this regard, the alarm initiation position may be determined indirectly (e.g., from a control signal for the locking mechanism) or directly (e.g., via a position detector). This makes the operation of the two-wheeled vehicle lock, in particular of the alarm device, comfortable and particularly failsafe.
Advantageous embodiments of the invention can be seen in the dependent claims, the description and the drawings.
In some embodiments, the two-wheeled vehicle lock may be configured such that the alarm device is automatically activated by moving the locking mechanism to the alarm activated position.
In some embodiments, the locking mechanism is designed to be purely mechanical.
In particular, the locking mechanism may have a lock cylinder which can be actuated rotationally by a key. The lock cylinder may be directly or indirectly connected to one or more latches to release the retaining ring in the unlocked position and to lock the retaining ring (assuming it is in the secured position) to the lock body in the locked position. In some embodiments, the alarm device is directly or indirectly activatable by rotational actuation of the lock cylinder by means of a key, wherein the lock cylinder is moved to an alarm activation position, wherein the alarm activation position is different from the unlocked position and the locked position or the first locked position.
In some embodiments, the lock cylinder may have a cylinder housing and a cylinder core rotatably supported in the cylinder housing, wherein a locked position of the locking mechanism corresponds to a first rotational position of the cylinder core, wherein an alarm-activated position of the locking mechanism corresponds to a second rotational position of the cylinder core, and wherein an unlocked position of the locking mechanism corresponds to a third rotational position of the cylinder core. Thus, the user can easily distinguish the different positions or states of the locking mechanism from each other, and can select these positions or states without an operational error.
In some embodiments, it can be provided that the lock cylinder can be started from the unlocking position into a first rotational direction or a second rotational direction opposite to the first rotational direction. Thus, the unlocked position forms a central position for actuating the lock cylinder to selectively move the locking mechanism or lock cylinder to different positions. In other embodiments, it can be provided that the lock cylinder can be started from the locking position into a first rotational direction or into a second rotational direction opposite to the first rotational direction. Thus, the locking position forms a central position for activating the lock cylinder.
In some embodiments, the first, second and third rotational positions of the cylinder core may in each case be offset by 90 ° with respect to one another. Thus, the clear, easily visible difference in the different rotational positions enables the user to operate the locking mechanism without error. For example, the first rotational position of the cylinder core may be offset by an angle of 90 ° with respect to the third rotational position of the cylinder core, wherein the second rotational position of the cylinder core is offset by an angle of 90 ° with respect to the third rotational position of the cylinder core and by an angle of 180 ° with respect to the first rotational position of the cylinder core.
In some embodiments, the key may be introduced into the cylinder core and may be removed from the cylinder core in two different positions of the cylinder core. Two different positions of the locking mechanism can thereby be selected, wherein the associated key can be removed from the lock cylinder. In particular, the two different positions may be two locking positions to lock the securing ring to the lock body (with the alarm device activated or deactivated), respectively. For example, it can be provided that an associated key can be introduced into the cylinder core and can be removed from the cylinder core in a first rotational position of the cylinder core and in a second rotational position of the cylinder core.
In some embodiments, the plug may have a plurality of pins that are moved into the plug core by the introduction of a key into the plug core. The specific combination of each plug may be encoded by the plurality of pins.
In particular, the lock cylinder may be configured as a disc tumbler lock cylinder having a plurality of disc tumblers, such as is known from DE102014108355 a 1. Disc tumbler lock cylinders constitute a possible configuration in which the associated key can be removed from the cylinder core in two different rotational positions, in particular, shifted by 180 ° with respect to each other.
With regard to the mechanical locking of the securing ring to the lock body, in some embodiments, the locking mechanism may have one or more latches that lock the securing ring at the lock body if it is in a secured position. In particular, the locking mechanism may have at least one latch which is drivable by an associated key (in particular via the lock cylinder) and which engages with the securing ring at a locking position of the locking mechanism to lock the securing ring to the lock body.
In some embodiments, a latch or another latch that may be driven by the lock cylinder may engage the retaining ring at an alarm activated position of the locking mechanism. In this regard, the alarm activated position may form another locked position of the locking mechanism.
In some embodiments, the securing ring may have at least one locking recess, wherein the latch engages into the locking recess when the locking mechanism is in the locked position (or in another locked position). In the unlocked position of the locking mechanism, the respective latch does not engage in contrast into the associated locking recess or recesses of the securing ring. The corresponding locking recess may be formed, for example, as a groove or a hole.
In some embodiments, the lock cylinder may be coupled to at least one latch via a deflection device that deflects rotational motion of the lock cylinder into linear motion of the latch. The deflection means may have at least one eccentric extension (e.g. a pin), another cam or ramp, wherein an associated reversing element (e.g. a guide path, slotted section or reversing ramp) can be provided. One element of the deflection device may be associated with the lock cylinder and another element of the deflection device may be associated with the corresponding latch. The linear movement of the latch may be a lateral movement, in particular a radial movement, with respect to the rotational axis of the lock cylinder, or may be an axial movement, in particular an axial movement which is offset coaxially or parallel to the rotational axis of the lock cylinder.
However, in other embodiments, a rotational or pivoting movement of the respective latch can also be provided, wherein the lock cylinder can be coupled directly to the at least one latch or indirectly, in particular via a deflection device.
As an alternative to purely mechanical embodiments, in some embodiments the locking mechanism may be designed in an electromechanical fashion.
In particular, the locking mechanism may have an electric motor which serves as an actuating motor, in particular for driving at least one latch of the locking mechanism. Such a motor may be coupled directly or indirectly to one or more latches to release the securing ring in the unlocked position and to lock the securing ring (assuming it is in the secured position) at the lock body in the locked position. In some embodiments, the alarm device can be activated directly or indirectly by a rotational movement of the electric motor, wherein a drive element or the electric motor arranged downstream is moved into an alarm activation position which is different from the unlocking position and the locking position or the first locking position.
In an electromechanical embodiment, the locking mechanism can therefore also have at least one latch which can be electrically driven for a locking and/or unlocking movement and which engages with the securing ring in the locking position of the locking mechanism to lock the securing ring at the lock body.
The actuation of the electromechanical locking mechanism by the authorized user may be realized, for example, by means of an electronic identification device (e.g. a transponder), a code transmission (e.g. by radio, in particular by a mobile terminal device), an actuation of a switch provided at the two-wheeled vehicle lock, or a combination thereof.
As an alternative to an electric motor, the electromechanical locking mechanism can have, for example, an electromagnetic drive.
In some embodiments, the alarm activated position of the locking mechanism as already mentioned may form another locking position, i.e. if the securing ring is in a fixed position, the securing ring may be locked at the lock body in the locking position and the alarm activated position. In these embodiments, the alarm device may be deactivated in one locked position, wherein the alarm device is activated in another locked position. Thus, in addition to the unlocked position, the user can select one of two different locking positions, wherein the alarm device can be deactivated, wherein the securing ring is likewise mechanically locked (in particular purely mechanically or electromechanically), but the alarm device is activated or deactivated.
Such an embodiment is particularly suitable for two-wheeled vehicle locks with so-called positive locking, wherein the locking mechanism must be moved to the locking position in order to be able to remove the associated key. Thus, by actuating the locking mechanism to lock the securing ring by means of the relevant key, the user can not only achieve the desired mechanical locking, but also simultaneously and in a simple manner select whether the alarm device should be activated or not.
In some embodiments, the securing ring can have at least one first locking recess and at least one second locking recess, wherein the securing ring is locked at the first locking recess in a locking position of the locking mechanism, and wherein the securing ring is locked at the second locking recess in another locking position of the locking mechanism. It is thus possible that the locking mechanism can assume different locking positions (for example different rotational positions of the lock cylinder, the electric motor or a drive element arranged downstream) in which the locking of the securing ring takes place, wherein different states of the warning device can be selected or set by means of the different locking positions.
In some embodiments, the locking mechanism can have two latches, wherein one of the two latches engages into a first locking recess of the securing ring in a locking position of the locking mechanism, and wherein the other of the two latches engages into a second locking recess of the securing ring in another locking position of the locking mechanism.
In particular, in this embodiment with two latches, it can be provided that, when the locking mechanism is actuated in a first rotational direction, the two latches are driven in a mutually opposed manner, and that, when the locking mechanism is actuated in a rotational direction opposite to the first rotational direction, the two latches are also driven in a mutually opposed manner. Thus, a similar movement of the latch (i.e. in a manner opposite to each other) is provided despite the different actuation directions of the locking mechanisms, wherein the desired state of the alarm device can be selected by the actuation direction.
In particular, it can be provided in some embodiments that the securing ring has a first ring end and a second ring end, each ring end having a first locking recess and a second locking recess, wherein in the locking position of the locking mechanism one of the two latches engages into the first locking recess of the first ring end and the other latch engages into the first locking recess of the second ring end, and wherein in the other locking position of the locking mechanism one of the two latches engages into the second locking recess of the second latch and the other of the two latches engages into the second locking recess of the first ring end.
However, the locking mechanism does not absolutely have to have two latches. In some embodiments, the locking mechanism may have only a single latch which, starting from the unlocked position of the locking mechanism, moves in the same direction independently of the direction of locking actuation of the locking mechanism (in particular independently of the direction of rotational actuation of the lock cylinder or the motor). In particular, it can be provided that, starting from the unlocked position of the locking mechanism, actuation can take place in two different directions in order to move the locking mechanism into the respective locked position, for example by rotational actuation of the associated key in two different rotational directions. In this respect, the two different actuation directions may achieve the same locking movement direction of the latch. For this purpose, it can be provided that the locking mechanism has a deflection device (in particular the already named deflection device) with mutually symmetrical drive portions which drive the latch in the same direction independently of the actuating direction of the locking mechanism. Such a deflection device may have, for example, mutually symmetrical ramps, by means of which the latch is driven. However, the two different actuation directions of the locking mechanism may differ from each other with respect to the control of the alarm device in that, for example, the respective position detector (e.g. sensor or switch) is addressed in only one of the two possible actuation directions (e.g. by a permanent magnet or a raised portion).
In some embodiments, the alarm device may be alternately enabled and disabled by multiple movements of the locking mechanism to the alarm enabled position. The desired state of the alarm device can thus be selected by temporarily moving the locking mechanism to the alarm activated position, without the locking mechanism having to remain in the alarm activated position. In particular, switching between the activated state of the alarm device and the deactivated state of the alarm device may be achieved by moving the locking mechanism to the alarm activated position accordingly. Thus, it is for example possible to specifically set the two positions (locked and unlocked position) or the mechanical locking function of the locking mechanism and to specifically set the other position (alarm activation position) for activating the alarm device.
In particular, such an embodiment is suitable for a two-wheeled vehicle lock with a so-called automatic function, wherein, unlike the forced locking, an automatic locking of the securing ring at the lock body takes place, wherein the securing ring enters the securing position from the open position, the locking mechanism is moved briefly from the locking position into the unlocked position and automatically back into the locking position. In particular, such automatic return to the locked position may be based on a spring preload of the locking mechanism. For example, at least one spring-loaded latch can be pushed back briefly by the securing ring while the securing ring is introduced into the lock body, and then the respective latch can be latchingly engaged at the securing ring.
With such a two-wheeled vehicle lock with automatic function, the alarm-activated position of the locking mechanism can be set by actuating the locking mechanism, for example by means of an associated key, which can be done against a spring preload (in particular against a spring preload provided in addition to the spring preload for the automatic function). Thus, the authorized user can also select the desired state of the alarm device (activated or deactivated) by the fact that he needs the key for unlocking the locking mechanism anyway. Alternatively, different kinds of actuation of the electromechanical locking mechanism may be provided to selectively activate the alarm device.
Independent of the embodiment of the locking mechanism, the two-wheeled vehicle lock may have a position detector configured to determine whether the locking mechanism is in the alarm activated position. Thus, the position detector may be used to determine whether a particular state of the alarm device is to be set based on the set state of the locking mechanism. The position detector may have a suitable sensor system for this purpose. The position detector may be configured to generate a positive determination signal if the position detector determines that the locking mechanism is in the alarm enabled position. In some embodiments, the position detector may be part of the evaluation and control circuitry of the alarm device. The position detector may be helpful or configured for activating the alarm device if it is determined that the locking mechanism is in the alarm activated position. In some embodiments, the position detector determines that the locking mechanism is only momentarily in the alarm activated position is sufficient for this purpose.
In some embodiments, the position detector may have a magnetic field sensor, a magnetic switch (e.g., a reed switch), or a contact switch. In particular, the magnetic field sensor or the magnetic switch may cooperate with a permanent magnet that is connected to an element of the locking mechanism (e.g., a latch, a key cylinder, a motor, a drive element, or a deflection device) and that moves relative to the magnetic field sensor or the magnetic switch upon actuation of the locking mechanism. Depending on the relative position between the magnetic field sensor or magnetic switch and the permanent magnet, it can be determined whether the locking mechanism is in the alarm activated position. In particular, the contact switch may cooperate with a raised portion (e.g., a latch, a key cylinder, a motor, a drive element, or a deflector) formed at an element of the locking mechanism and move relative to the contact upon actuation of the locking mechanism.
The alarm means of the two-wheeled vehicle lock may be configured to output an acoustic and/or optical alarm signal upon detection of a manoeuvre attempt at the lock, for example by determining a change in position or vibration of the lock when the device has been activated and is in a monitoring operating state.
In some embodiments, the alert device may have at least one (specifically, a plurality or all) of the following components:
a power source for providing power to other components of the alarm device;
an acceleration sensor or a vibration sensor;
an evaluation and control circuit;
an acoustic and/or optical signal generator; and/or
A radio transmission unit for wirelessly transmitting the alarm signal.
The power source herein may include one or more commercial batteries and/or rechargeable batteries.
With respect to the acceleration sensor, it may be configured as a static acceleration sensor and/or a dynamic acceleration sensor, wherein the static acceleration sensor may be configured as an inclinometer for identifying alignment and/or position changes (gravity detection), and the dynamic acceleration sensor may be used to identify time-dependent accelerations (e.g., based on blows applied to the lock). In particular, the acceleration sensor or the associated evaluation and control circuit may compare one or more detected acceleration values with corresponding threshold values. Therefore, the acceleration sensor may also be configured as a vibration sensor. However, it is also possible to provide a different kind of vibration sensor, which in particular can directly detect the predetermined vibration.
In some embodiments, the evaluation and control circuit may be configured to evaluate the signal of the position detector. In addition, the evaluation and control circuit may be configured, in particular, to evaluate the signal of the acceleration sensor or of the vibration sensor, so as to trigger the output of an alarm signal when a change in position or a vibration is detected during the monitoring operation (for example on the basis of a comparison with a threshold value). In some embodiments, the evaluation and control circuitry may be configured to trigger the output of the pre-warning signal first upon detection of a change in position or vibration, and to trigger the output of the primary alarm signal only after the passage of a primary alarm delay interval and continued detection of a change in position or vibration. The evaluation and control circuit may also be configured to take into account a motion detection delay interval, for example the known brake disc lock of DE102005043927a 1.
The acoustic and/or optical signal generator may for example comprise a loudspeaker, in particular a piezoelectric loudspeaker, and/or a light emitting diode.
As an alternative or in addition to the output of an acoustic or optical alarm signal, the two-wheeled vehicle lock may have a radio transmission unit for wirelessly transmitting the alarm signal, in particular to a radio receiving unit of an authorized user. Such a radio receiving unit may be a separate device associated with a two-wheeled vehicle lock (e.g., a named radio control unit) or a cellular telephone. The signal transmission may be according to a common standard (e.g. bluetooth, wireless LAN, GSM).
In some embodiments, in particular those with an automatic function of a positive locking or locking mechanism, it can be provided that the alarm device outputs an acoustic and/or optical confirmation signal when a particular state of the alarm device is set. In particular, it can be provided that different confirmation signals (for example, different sound sequences or pitches or different colors of the light signal) are output depending on whether the alarm device has been activated or deactivated. In particular, the output of such an acknowledgement signal may be triggered by the evaluation and control circuit.
With regard to the design and function of the securing ring, in some embodiments, the securing ring may be fully released from the lock body in the open position (e.g., by a so-called U-ring). In other embodiments, the securing ring may be permanently fixed at the lock body, but may be movably supported at the lock body. For example, the securing ring may be permanently (in particular rigidly or rotatably or pivotably) secured at one end to the lock body, wherein different free ends of the securing ring can be selectively locked at the lock body.
In some embodiments, the securing ring may be U-shaped and have two ring ends, wherein the lock body has two introduction openings for receiving the ring ends.
In some embodiments, the retaining ring may be rigid. In other embodiments, the securing ring may be flexible (particularly in the form of a wire rope or chain). In some embodiments, the securing ring may be configured as a connecting rod having a plurality of connecting rods pivotably connected to one another.
In some embodiments, the two-wheel vehicle lock may be configured as a U-hoop lock (e.g. known from DE 10026701 a1 or DE 102007035122 a1), a folding lock with a connecting rod (e.g. known from DE102005040066 a1), a brake disc lock (e.g. known from DE102005043927a 1), or a frame lock. In particular, such a frame lock may have a rotatable ring (for example known from (DE 10252080 a 1)), a pivoting hoop (for example known from DE 102011015313 a1), or a linearly movable hoop (for example known from DE 102012002903 a 1).
The two-wheel lock can be a portable lock and can also be fixedly arranged on the two-wheel vehicle.

Starting from the unlocked position, the cylinder core 44 can be selectively actuated in rotation by the key 42 into a first direction of rotation or into a second direction of rotation opposite thereto. Thus, the unlocked position forms a central position for actuating the lock cylinder to selectively move the
In this regard, the first, second and third rotational positions (corresponding to the central position of the cylinder core 44) may be offset from each other by 90 °. In other words, the first rotational position of the cylinder core 44 may be offset by an angle of 90 ° with respect to the third rotational position, and the second rotational position of the cylinder core 44 may be offset by an angle of 90 ° with respect to the third rotational position and by an angle of 180 ° with respect to the first rotational position. Thus, the clear, easily visible distinction of the different rotational positions enables the user to operate the
