Description

[0001] The present invention relates to a locking device with a clamp which is designed to be inserted into a clamp receptacle of an associated lock body and locked in the clamp receptacle.

[0002] To secure a movable object, particularly against theft, it can be fixed to another, immovable object. For example, bicycles are typically secured against theft by locking them to an immovable object, such as a bicycle rack or lamppost, using a bicycle lock, provided the lock is designed for this purpose and a suitable immovable object is available. Alternatively, the movable object can be locked in such a way that unauthorized movement of the object is at least made more difficult and / or that the object is unusable when locked. For instance, a bicycle lock can block one wheel of a bicycle being secured, preventing the bicycle from being ridden or easily pushed away.Some bicycle locks, especially if they form a sufficiently large loop when closed, can be used both for locking and for the described locking process, while frame locks or spoke locks, for example, are specifically designed for locking in the sense of internal blocking.

[0003] The security of any locking device used to protect a movable object from being moved depends on how easily, and therefore how quickly, the device can be bypassed. In principle, any locking device can be bypassed, at the latest by destroying it, if an attacker has sufficiently long, uninterrupted access to it (and, of course, possesses the necessary tools). Therefore, the security of a movable object protected by a locking device is enhanced if precautions are taken to ensure that attempted break-ins do not go unnoticed, but are signaled, in particular, by the transmission of an alarm.

[0004] For example, a bicycle lock can, in addition to preventing the bicycle from being moved, also have an alarm function, thus constituting a mobile alarm device. Alternatively, a separate mobile alarm device can be provided, which can be attached to the movable object independently of any mechanical locking or unlocking mechanisms. Since the mere emission of an alarm signal can alert the perpetrator to an attempted theft and deter the assailant, attaching such a mobile alarm device can be sufficient to reliably prevent the unauthorized movement of the movable object.

[0005] A mobile alarm device comprising a fastening means by which the alarm device can be attached to and locked on an object is described in DE 10 2017 111 833 A1. A hinged lock with an alarm device is known from DE 10 2017 105 031 A1. DE 10 2010 008 054 A1, DE 103 58 300 A1, and DE 102 52 080 A1 each describe a bicycle lock, which can, for example, be designed as a frame lock and, in addition to a locking bolt, has a clamping receptacle for a clamp of a safety cable. DE 10 2010 025 383 A1 describes a loop lock.

[0006] It is an object of the invention to provide a locking device for detachable attachment to a lock for securing a movable object, in particular a two-wheeler, which offers increased security against manipulation attempts while being easy to use.

[0007] This problem is solved by a safety device having the features of claim 1 and in particular by the fact that the safety device has an alarm module with an alarm device for outputting at least one alarm signal.

[0008] The alarm module is attached to the clamp directly or indirectly, in particular via a securing element, for example a safety cable or chain (as explained below). The securing device thus forms an autonomous alarm unit and is characterized in particular by the fact that it can be attached to an associated lock, for example a frame lock of a bicycle, by means of the clamp, e.g., rigidly or rotatably. In particular, the securing device can also be retrofitted to an existing lock of the user. With frame locks, it is often problematic to accommodate an alarm system including the necessary electronics and power supply. The securing device according to the invention is characterized in that the alarm module can be housed outside the frame lock or the lock body.When the frame lock is engaged, the clamp of the locking device, including the alarm module attached to the clamp, can also be secured to the frame lock, depending on the design of the frame lock. When the frame lock is disengaged, i.e., a locking bolt (e.g., a shackle) of the frame lock is open for riding the bicycle, the locking device can, depending on the design of the frame lock, be disengaged, remain locked, or at least be attached to the clamp receptacle of the frame lock via a releasable latch. Furthermore, the locking device according to the invention can be used not only in conjunction with such a frame lock, but also in combination with other types of locks, for example, cable locks or loop locks, which have a clamp receptacle for the clamp of the locking device according to the invention.

[0009] At least one alarm signal can be issued, for example, in the form of a visual, an acoustic and / or a radio-transmitted alarm signal.

[0010] The alarm module can form a base body of the security device, with the clamp being firmly connected to the base body and protruding from the base body.

[0011] According to one embodiment, the clamp is pin-shaped at least in a free insertion section provided for insertion into the clamp receptacle. The insertion section of the clamp can have at least one locking recess and / or an insertion chamfer. The clamp or the insertion section can, in particular, be designed as a cylindrical bolt, i.e., straight and elongated with a circular cross-section. The locking recess can, for example, be designed as a detent, annular groove, or lateral groove. In principle, several locking recesses can also be provided. The insertion chamfer can be provided as a circumferential chamfer or as a lateral chamfer at the free end of the clamp. The alarm module is provided at the end opposite the free end of the clamp.

[0012] According to a further embodiment, the alarm module is permanently attached to the hinge pin in such a way that it is impossible to detach the alarm module from the hinge pin, at least when the hinge pin is locked in the hinge pin receptacle of the associated lock body. This permanent attachment means, in particular, that the alarm module cannot be detached from the hinge pin without damage when the hinge pin is locked in the hinge pin receptacle. In particular, a mechanical connection between the alarm module and the hinge pin, or (optionally additionally) with a locking element, especially a flexible locking element such as a locking cable or chain, may be provided. Such a locking element may be attached to the end of the hinge pin opposite its free end. The mechanical connection may, for example, be provided at a fastening point between the hinge pin and the locking element.If the hinge pin is not locked in the hinge recess of the associated lock body, the alarm module can be detached from the hinge pin, for example, for disposal purposes. This allows compliance with legal requirements that mandate the separate disposal of electronic or electrical components. Detaching the alarm module can be done without tools, for example, by attaching the alarm module to the hinge pin with a snap-fit ​​connection.

[0013] In some embodiments, the alarm device includes at least one of the following components: - an accelerometer, - an evaluation and control circuit, - an acoustic and / or an optical signaling device for emitting an alarm signal, and / or - a radio transmitter unit for wirelessly transmitting an alarm signal.

[0014] Alternatively or additionally, the alarm module can include an electrical power source to supply power to the alarm system. Using the aforementioned components of the alarm system, tampering attempts on an object secured by the security device or on the security device itself can be detected, and at least one alarm signal can be issued. For example, the accelerometer can detect movement of an object secured by the security device and / or register a forced entry attempt on the lock and / or an attempt to destroy or remove the alarm module. In the evaluation and control circuit, measured values ​​from the accelerometer can be evaluated and processed, and, if necessary, the aforementioned signal transmitter can be activated to issue the alarm signal, or the radio transmitter can be instructed to wirelessly transmit an alarm signal.The electrical energy source, for example a battery or a rechargeable battery, can provide the electrical energy necessary to operate the alarm device.

[0015] One possible way in which such an alarm device can be used is described in detail, for example, in DE 10 2017 111 833 A1, the content of which is incorporated in full into the present application by reference.

[0016] According to one embodiment, the alarm module surrounds at least the clamp completely, particularly concentrically. The alarm module can, for example, have a substantially cylindrical shape, with the elongated clamp extending axially and preferably coinciding with the axis of symmetry of the alarm module. The alarm module can also surround an end section of a locking element connected to the clamp, so that a connection point between the clamp and the locking element is located within the alarm module. These measures ensure good handling of the locking device, as they allow the individual components of the alarm module to be distributed evenly around the circumference of the clamp in a space-saving manner.Since the alarm module completely surrounds the hinge, access to any interface or connection point between the alarm module and the hinge is also made more difficult, thus improving security against attempts at manipulation or destruction, especially the forced removal of the alarm module from the hinge.

[0017] As an alternative to a coaxial design, a longitudinal axis of the clamp and a longitudinal axis of the alarm module can also be aligned at an angle to each other other than 0°, in particular at an angle of 90°. In some embodiments, the clamp and the alarm module can be articulated together.

[0018] Advantageously, the alarm module has an access opening for inserting and / or removing components of the alarm module, in particular an electrical power source for the alarm device. This access opening is arranged such that it is concealed or inaccessible when the bolt is inserted into the bolt receptacle of the associated lock body and, in particular, locked. These measures prevent manipulation or disabling of the security device by unauthorized removal of individual components. No further measures are required to secure the access opening. It is generally sufficient to provide a cover for the access opening as protection against dust or moisture, which cannot be opened or removed when the bolt is locked.

[0019] In this context, it can be advantageous if the access opening is located on an end face of the alarm module surrounding the clamp and / or on an end face of the alarm module facing the clamp receptacle. The access opening can also, in particular, provide access to a fastening device that secures the alarm module to the clamp and whose actuation allows the alarm module to be released from the clamp.

[0020] According to a further advantageous embodiment of the invention, the alarm module has a contact switch connected to the alarm device, which is configured to detect when the bolt is inserted into the bolt receptacle of the associated lock body and / or when the bolt is locked in the bolt receptacle of the associated lock body, wherein the alarm device is configured to be activated depending on a switching state of the contact switch. Accordingly, the contact switch is configured to detect a relative position of the locking device with respect to the associated lock body. This relative position can be evaluated in a suitable manner. For example, if the bolt is located within the bolt receptacle and, in particular, is locked there, the alarm device can be activated or be capable of being activated.This activation, however, does not have to be exclusively and necessarily via the contact switch. An AND gate with a mode switch can also be used, for example, allowing the locking device to be selectively placed in either an alarm mode or a transport mode. In transport mode, the bicycle can be moved while the locking device is in the clamp mount without triggering an unintentional alarm. Only in alarm mode can the alarm be activated by the contact switch.

[0021] In this context, it can be advantageous if the contact switch includes an actuating element located on an end face of the alarm module surrounding the clamp and / or facing the clamp receptacle. This end face is the one facing the clamp receptacle when the locking device is received and, in particular, locked in it. This makes it possible to arrange the contact switch inside the alarm module in a tamper-proof manner, with the actuating element being able to transmit any adjustment of the actuating element caused by inserting the locking device into the clamp receptacle to the contact switch. The actuating element can, in particular, be a pin or lever (preferably spring-loaded) which, for example, can be displaced parallel to a longitudinal axis of the locking device or the clamp.

[0022] In some embodiments, the clamp can be configured to latch or lock at two different insertion depths in the clamp receptacle of the associated lock body, with the contact switch being configured to be inactive at the first insertion depth and activated at the second. The second insertion depth is, in particular, greater than the first. Thus, it is possible, for example, to lock the clamp at the first insertion depth in the clamp receptacle for transport purposes or while driving, in which the locking device is secured against loss, but the alarm device is not yet activated.To activate the alarm device, possibly also depending on the position of the aforementioned mode switch, the clamp can be locked at the second insertion depth, whereby the contact switch can transmit a corresponding activation signal to the alarm device.

[0023] In such an embodiment, the bolt can have a first and a second locking recess, in particular designed as a locking groove, which are intended to interact with a locking mechanism of the associated lock body. The first insertion depth is defined by the interaction of the locking mechanism with the first locking recess, and the second insertion depth is defined by the interaction of the locking mechanism with the second locking recess. The two locking recesses can, in particular, define a respective engagement position in which the bolt is held securely in the respective insertion depth within the bolt receptacle of the lock body. For this purpose, the locking mechanism of the lock body can, in some embodiments, include a spring-loaded engagement element (e.g., a bolt).By providing the two locking recesses, a latch can be implemented in a particularly simple manner which can be engaged or locked at two different insertion depths without requiring any modifications to the lock body or the locking mechanism. This also makes it possible to engage or lock the inventive locking device on lock bodies that are not specifically configured to accommodate a latch with two different insertion depths.

[0024] In some embodiments, the alarm module has a mode switch connected to the alarm device, which is configured to selectively put the alarm device into either a transport mode or an alarm mode. In transport mode, the alarm device is inactive, and in alarm mode, it is active or can be activated. This mode switch can be provided as an alternative to, or in addition to, the aforementioned contact switch. In an embodiment where the alarm device is (necessarily) active in alarm mode, the contact switch is not required. In an embodiment where the alarm device can be activated in alarm mode, but is not necessarily active, the switching state of the aforementioned contact switch or a comparable device can also be taken into account to actually activate the alarm device.In this case, the alarm mode can first be preselected using the mode switch, and the alarm device can only actually be activated by actuating the contact switch, i.e., in particular by inserting or locking the clamp in the clamp receptacle.

[0025] In an embodiment with a selectable transport mode, it is possible that the alarm device remains inactive in transport mode even when the bolt is inserted into the bolt receptacle of the associated lock body and, in particular, locked. If the mode switch is provided in addition to the aforementioned contact switch, the mode switch, in particular, overrides any activation triggered by the contact switch in transport mode.

[0026] In an embodiment with a mode switch, the mode switch can be actuated by a user mechanically and / or electrically by means of a wireless signal, in particular a radio signal. The mode switch can, for example, be designed as a slide switch or as an on / off push button that controls a bistable switching element or flip-flop, the state of which puts the alarm device into transport mode or alarm mode. The wireless signal for electrical actuation of the mode switch can be transmitted, for example, by means of a suitable operating device, such as a radio or infrared remote control, or via the user's smartphone, for example, via a WLAN or Bluetooth connection. Transmission of the wireless signal from an associated lock, in particular a frame lock, is also possible, for example, depending on the position of a locking bolt of the frame lock.If the mode switch is designed as an on / off button that controls a bistable switching element, the state of the switching element can optionally also be switched using the wireless operating device.

[0027] If the mode switch is a mechanically operated switch, it can be located on an end face of the alarm module surrounding the bolt and / or facing the bolt receptacle. The mode switch, which can be designed, for example, as a slide switch or push button, can thus be operated by the user before the locking device is inserted into the bolt receptacle or locked to the associated lock body. After the locking device is inserted into the bolt receptacle or locked, the mode switch is no longer accessible and therefore cannot be operated tamperingly or accidentally. Alternatively, the mode switch can be electrically or mechanically locked in its current position when the aforementioned contact switch is actuated.

[0028] The alarm system can be deactivated, in particular, using the contact switch, for example, automatically by unlocking and releasing the locking device from the associated lock body. Alternatively or additionally, the alarm system can also be deactivated using the mode switch by setting the transport mode. In both cases, after detecting a change in position and / or a vibration, a waiting interval can be observed before an alarm signal is issued, allowing the authorized user sufficient time to unlock the associated lock body and subsequently deactivate the alarm system.

[0029] In some embodiments, the safety device may consist solely of the clamp and the alarm module. In particular, the safety device may also be designed without the aforementioned safety element (e.g., safety cable or safety chain).

[0030] In some embodiments, however, the safety device further comprises an elongated, flexible safety element. This elongated, flexible safety element may, for example, be a safety cable or a safety chain. The safety element may be rigidly connected to the clamp at one end. If, as mentioned, the alarm module forms a base body of the safety device, the clamp may protrude from the base body on one side, and the safety element may protrude from the base body on another side, particularly an opposite side.

[0031] In some embodiments, the securing element can have an eyelet at its free end, opposite the clamp, in particular a rigid or a flexible eyelet (e.g., a folded rope end or ring). A loop can be formed using the eyelet by first passing the clamp through the eyelet and then locking it in the associated clamp receptacle, for example, to secure a bicycle to a fixed object.

[0032] The invention further relates to a lock with a locking device according to one of the aforementioned embodiments and with the associated lock body, wherein the lock body has the bolt receptacle for the bolt and a locking mechanism, and wherein the bolt received in the bolt receptacle can be locked to the lock body by means of the locking mechanism. The locking mechanism can, for example, be operated by means of a key, as is generally known.

[0033] In some embodiments, the lock may have an elongated, flexible locking element (as explained above), wherein the locking element has a first end connected to the locking device or the bolt and a second end opposite the first end, the second end of the locking element having an eyelet or being permanently attached to the lock body. The locking element connected to the locking device is thus either designed as a separate element of the lock (e.g., a locking cable or chain for a frame lock), or it forms a unit with the lock body (e.g., a locking cable or chain that can be gathered into a closed loop and locked).

[0034] According to one embodiment, the lock body is designed as a frame lock for a two-wheeler and includes a locking bolt that is adjustable between a closed and an open position. The locking mechanism is configured to lock both the clamp and the locking bolt to the lock body, either directly or indirectly. Alternatively, an additional locking mechanism for the clamp can also be provided. A frame lock is a lock in which the locking bolt blocks the rotation of a wheel of the vehicle or two-wheeler in the closed position and releases it in the open position. The locking bolt can, in particular, engage in the space between two spokes of the wheel.

[0035] Alternatively, the lock can also be designed as a loop lock, in particular a chain lock or a cable lock, to form a closed loop. In such an embodiment, the first end of the locking element is permanently connected to the bolt, and the second end of the locking element is permanently connected to the lock body. An advantage of this embodiment is that the alarm device does not need to be housed in the lock body (which has the bolt receptacle), but can be located on the side of the bolt.

[0036] The invention also relates to the use of a security device of the type described for equipping a lock body, in particular an existing lock body, with an alarm module. This allows, for example, an existing bicycle frame lock, which has a lockable clamping receptacle for an associated security element, to be easily retrofitted with an alarm device.

[0037] Further embodiments of the invention are described in the dependent claims, the description, and the drawings. Advantageous further developments of the invention can also be achieved by combining features for which a combination is not explicitly described.

[0038] The invention is described below with reference to an exemplary embodiment and the drawings. The drawings show: Fig. 1 a side view of a locking device mounted in a hinge receptacle of a lock body according to an embodiment of the invention; Fig. 2 a sectional view of the safety device of Fig. 1; and Fig. 3 a front view of the locking device of Fig. 1 and Fig. 2.

[0039] Fig. Figures 1 to 3 show a safety device 10 with a clamp 12, which has an alarm module 14. In the illustrations according to Fig. 1 and Fig. 2 The clamp 12 is received in a clamp receptacle 52 of a lock body 50, for example a lock body of a bicycle frame lock, and can be latched and locked in the clamp receptacle 52 by means of locking elements 54. The in Fig. 1 and Fig. The lock body 50, shown in section 2, is not an integral part of the locking device 10 and is therefore only indicated schematically by dashed lines. Locking the bolt 12 in the bolt receptacle 52 can be achieved by means of a generally known locking mechanism, which can actuate or control the locking elements 54 such that they either lock the bolt 12 in the bolt receptacle 52 or release it for removal. It should be noted that the additional detent function of the locking elements 54 (force-locking holding of the bolt 12 in the unlocked state) is not strictly necessary.

[0040] The clamp 12 is essentially cylindrical, at least at its insertion section projecting from the alarm module 14, and has a circumferential conical insertion chamfer 20 at a first, free end. Furthermore, two spaced-apart locking recesses in the form of circumferential locking grooves 18a, 18b are provided on the circumferential side of the clamp 12, wherein, depending on the insertion depth of the locking device 10 into the clamp receptacle 52, the locking elements 54 interact either with the locking groove 18a or the locking groove 18b.

[0041] In the present embodiment, the clamp 12 is permanently connected to an elongated, flexible securing element 34, for example, a securing cable or chain. According to a modification not shown, the securing element 34 can also be omitted, i.e., the securing device 10 comprises only the clamp 12 and the alarm module 14.

[0042] The alarm module 14 surrounds the clamp 12 along its circumference, with the alarm module 14 covering the connection between the clamp 12 and the locking element 34. The alarm module 14 can be permanently attached to the clamp 12, for example, by means of a suitable fastening device, such as a snap-fit ​​or screw connection, which is not accessible from the outside. The alarm module 14 includes a cavity in which various components of the alarm module are arranged. These components include an alarm device 16, an electrical power source 24 for supplying the alarm device 16 with electrical energy, and an actuating element 30, which penetrates an end face 28 of the alarm module 14 facing the clamp receptacle 52.When the locking device 10 is inserted into the clamp receptacle 52, the actuating element 30 can come into contact with the lock body 50 and thereby be displaced in an axial direction, which actuates a contact switch integrated in the alarm device 16 (not shown separately).

[0043] The alarm device 16 can, for example, comprise an accelerometer, an evaluation and control circuit, and at least one device for outputting an alarm signal, wherein the device for outputting an alarm signal can include an acoustic and / or an optical signal generator and / or a radio transmitter for wirelessly transmitting an alarm signal. In the present embodiment, a concealed acoustic signal generator (not shown) and an optical signal generator 22 arranged on the outer circumference of the alarm module 14 are provided. A radio transmitter (not shown) can be integrated into the alarm device 16.

[0044] A mode switch 32 is also provided on the outer circumference of the alarm module 14, which is configured to selectively put the alarm device 16 into either a transport mode or an alarm mode. In transport mode, the alarm device 16 is inactive. In alarm mode, the alarm device 16 can be activated by means of the contact switch. When the alarm device 16 is in alarm mode and the bolt 12 is located outside the bolt receptacle 52 or in the bolt receptacle 52 at the first insertion depth, at which the locking elements 54 engage with the locking groove 18b, the alarm device 16 is still deactivated. If the locking device 10 or...When the bolt 12 is moved to the second insertion depth, in which the locking elements 54 engage with the locking groove 18a, the actuating element 30 comes into contact with the lock body 50 and is moved inwards into the alarm module 14, thereby actuating the contact switch provided in the alarm device 16. This actuation of the contact switch activates the locking device 10. In the activated state, the alarm device 16 reacts in particular to acceleration forces acting on the locking device 10. If these acceleration forces meet predefined criteria for triggering an alarm, the acoustic signal generator and the optical signal generator 22 can be activated and / or an alarm signal can be transmitted wirelessly.

[0045] The alarm module 14 also has an access opening 26 on its end face 28 surrounding the insertion section of the clamp 12. This opening allows, among other things, the removal and / or insertion of the power source 24. The access opening 26 can be closed by a removable cover (not shown), which protects the interior of the alarm module 14 from dirt and moisture. When the locking device 10 is locked to the lock body 50, the access opening 26 is covered by the lock body 50, so that it is not possible to disable the locking device 10 by unauthorized removal of the power source 24. The access opening also allows the snap-fit ​​or screw connection with which the alarm module 14 is attached to the clamp 12 to be released, which may be necessary, for example, for repair or disposal purposes.

[0046] According to a modification, the mode switch 32 can also be arranged on the front face 28 to prevent manipulation by intentionally or accidentally changing the set mode. The distance between the front face 28 of the module 14 and the lock body 50 is not shown to scale. This distance can also be minimized, in particular to ensure the best possible protection against manipulation.

[0047] In the illustrated embodiment, the mode switch 32 can be locked against unintentional or unauthorized actuation, for example, by coupling the mode switch 32 with the actuating element 30 in such a way that switching the alarm device 16 from alarm mode to transport mode by means of the mode switch 32, and thus deactivating the alarm device 16, is not possible when the locking device 10, as shown in Fig. 1 and Fig. 2 shown, in the second insertion depth is locked by the engagement of the locking elements 54 with the locking groove 18a.

[0048] According to a modification, instead of the mechanical mode switch 32, an electronic mode switch provided inside the alarm module 14 can also be used, which can, for example, be integrated into the alarm device 16 and can be actuated by means of a wireless signal, such as a radio or infrared signal. Signals for actuating the mode switch can be transmitted in encrypted form, in particular, to prevent manipulation of the security device 10.

[0049] If the lock body 50, as mentioned, is a lock body of a two-wheel frame lock, the elongated flexible locking element 34 can be attached to its other, in Fig. 1 and Fig. 2. The ends not shown have an eyelet so that a closed loop can be formed by threading the clamp 12 through the eyelet before the clamp 12 is locked in the clamp receptacle 52 (see, for example, DE 103 58 300 A1, there Fig. 1 and Fig. 2) According to an alternative embodiment, the elongated flexible locking element 34 can be attached to its other, in Fig. 1 and Fig. The 2 ends not shown, however, are also permanently connected to the lock body 50 to form a loop lock with alarm function.
