Description

The present invention relates to an articulated lock. Such an articulated lock comprises a lock body which has a locking mechanism, and an articulated bar bracket which has a plurality of articulated bars which are pivotally connected to one another and a locking bar. A first end of the hinge rod bracket is permanently attached to the lock body. The locking bar forms a free second end of the hinge bar bracket, wherein the locking bar can be locked to the lock body by means of the locking mechanism.

Such an articulated lock is used, for example, to secure a two-wheeler to a bicycle stand, a lamppost or the like, or to secure a two-wheeler against unauthorized driving away. For this purpose, the articulated bars of the articulated bar bracket, which are articulated one behind the other or in a row, are unfolded to form an open loop, which is guided, for example, around a frame section of the two-wheeler and the bicycle stand, lamppost or the like, or is merely guided through a rim of the two-wheeler. The locking bar is then locked on the lock body in order to thereby close the loop and thus secure the two-wheeler against unauthorized removal or unauthorized driving away.

For the transport of the articulated lock by the authorized user, the articulated rods and the locking rod can typically be folded into a compact arrangement - the so-called folding rule configuration. For this purpose, the joint rods and the locking rod are pivoted in the manner of a foldable folding rule and thereby brought into parallel alignment with one another.

Such a joint lock is from the document DE102005040066A1 known, the locking mechanism of this joint lock has a lock cylinder with positive guidance of the bolt. From the document DE102013210475A1 an articulated lock with an automatic function is known in which the locking bar (and thus the second end of the articulated bar bracket) can be automatically locked to the lock body by inserting the locking bar into a receiving opening of the lock body.

When not in use, an articulated lock of the type mentioned can be stored and transported in a storage device (for example a bag, quiver or holder), such as this one from the DE202005013390U1 is known. For this purpose, the jointed bar bracket is folded into the compact folding rule configuration mentioned.

In the event of a manipulation attempt on a joint lock of the type mentioned in order to steal a two-wheeler secured thereby, the time required for unauthorized opening of the joint lock is an important aspect. The less time a thief has, the more difficult it is to attempt manipulation.

It is therefore conceivable to equip the articulated lock with an alarm device which emits an acoustic and / or visual alarm signal as soon as a manipulation attempt is detected. In practice, however, convenient operation of such an alarm device by the authorized user is difficult, in particular with regard to arming the alarm device (hereinafter referred to as "activating" the alarm device). An alarm device that is sensitive to vibrations, for example, must not be triggered during the transport of the articulated lock and must not be activated every time the motorcycle is locked activation of the alarm device is also desirable (for example securing the two-wheeler to a bicycle rack of a motor vehicle).

It is therefore an object of the invention to provide an articulated lock which, with comfortable operation, offers increased security against manipulation attempts.

This object is achieved for an articulated lock with the features mentioned at the outset in that the lock body further comprises an alarm device for emitting an alarm signal, the locking bar being lockable on the lock body either in a first closed position or in a second closed position, the alarm device not being able to be activated is when the locking bar assumes the first closing position, and the alarm device can be activated or activated when the locking bar assumes the second locking position.

In the articulated lock according to the invention, the locking bar can optionally be locked in one of two different closed positions on the lock body. Furthermore, the articulated lock comprises an alarm device which, in the event of a detected attempt at manipulation, outputs an acoustic alarm signal, for example. With regard to the activation or arming of the alarm device, a first closed position of the locking bar forms an unset closed position, and a second closed position of the locking bar forms the arming closed position. In the first closed position, the locking bar can be locked on the lock body to secure the two-wheeler against unauthorized removal or unauthorized driving away; however, in the first closed position, the alarm device cannot be activated at the same time, especially not inadvertently. In the second closed position, however, the locking rod can be locked on the lock body and the alarm device can also be activated (or this happens automatically, as follows will be explained). The authorized user can thus determine whether or not the alarm device should be activated or activated by selecting the closing position of the locking rod. This results in comfortable and, in particular, also fail-safe operation of the articulated lock.

The joint lock according to the invention increases security against attempts at manipulation by providing an alarm device in addition to a locking function. The alarm device can be activated directly or indirectly via the locking rod. The two closed positions mentioned can be selected in a simple manner, for example, by simply moving the locking bar during the securing process of the two-wheeler. The equipment of the articulated lock with an alarm device helps to protect against possible manipulation attempts. The acoustic and / or visual alarm signal effectively shortens the time for an attempt at manipulation, since a thief must expect the user to arrive soon or the intervention of passers-by or law enforcement officers who have been made aware of the attempted manipulation by the alarm signal. As mentioned above, the time factor is crucial to prevent successful theft or at least to make it very difficult. Furthermore, it has been shown that knowledge of the presence of an alarm device alone has a deterrent effect on possible thieves. The two-stage and easy-to-use activation of the alarm device also takes into account situations in which the triggering of an alarm signal is not desired, but the two-wheeler should nevertheless be comprehensively secured, such as during transportation on a motor vehicle bicycle rack.

Advantageous embodiments of the invention can be found in the dependent claims, the description and the drawing.

According to one embodiment, the alarm device can be activated in that the locking rod is brought into the second closed position. The alarm device can thus be automatically armed for the user in a particularly simple and convenient manner, only one detector being required to detect the second closed position.

As an alternative to this, the alarm device can be activated in that the locking bar is brought into the second closed position and that the locking mechanism is also brought into a locking position in which the locking mechanism locks the locking bar on the lock body. In this embodiment, it is therefore necessary for the alarm device to be activated that the locking rod assumes the second closing position and that the locking rod is additionally locked on the lock body in the second locking position. A detection of whether the locking rod assumes the second closed position can be carried out, for example, by means of an assigned first detector. A detection whether the locking mechanism is in the locking position can be carried out by means of a second detector; For example, an actuating element can be provided on a movable element of the locking mechanism (e.g. locking element or driver), which actuates a contact switch in the locking position. The signals of the two detectors can be supplied with a logical AND link in order to activate the alarm device when the second closing position of the locking rod and the locking position of the locking mechanism are detected. In this embodiment, the waiting interval can be shortened, which must elapse before the start of a monitoring operation of the alarm device, so that the authorized user can properly end the locking process.

According to a further alternative, it is also possible for the alarm device to be activated in that the locking bar is brought into the second closed position and that an additional switching device is also actuated. A Detection as to whether the locking rod is in the second closed position can in turn be carried out by means of an assigned detector (for example contact switch). The additional switching device mentioned can be a switching device which can be operated from the outside, in particular a switch which is arranged on the lock body and which can be operated from the outside (for example a slide switch, rocker switch, pushbutton, etc.). Said additional switching device can, however, also comprise a switching device which can be operated wirelessly from the outside and which, for example, has a radio receiving unit and is controlled by means of its own radio remote control unit assigned to the articulated lock or by means of a cell phone (for example via Bluetooth, NFC, WLAN). In this embodiment, too, the signals of the closed position detector and the additional switching device can be supplied with a logical AND link in order to activate the alarm device if necessary.

According to one embodiment, the signal from the detector, which detects the second closed position of the locking bar, can be used to activate the alarm device directly. Or the signal of the detector is first evaluated and / or logically linked by an evaluation and control circuit of the alarm device.

With regard to the detector mentioned for detecting the second closed position of the locking rod, it can be designed, for example, for contactless detection of the locking rod, e.g. in the form of a Hall sensor or a reed switch.

According to an advantageously simple embodiment, the lock body can have a switch which is actuated directly or indirectly by means of the locking bar when the locking bar is brought into the second closed position. This can be done, for example, using a contact switch that has a direct (mechanical) Allows actuation of the switch by means of the locking rod. The switch can be actuated in particular by means of the tip of the locking rod.

According to one embodiment, the lock body can have an insertion channel for inserting the locking rod into the lock body, said switch being arranged in the lock body outside the insertion channel and outside an axial extension of the insertion channel, and wherein the lock body has a transmission element via which the switch can be actuated indirectly by means of the locking rod. Thus, the switch for detecting the second closed position of the locking bar can be arranged away from the insertion channel for the locking bar and in particular outside the alignment of the insertion channel for the locking bar. This protects the switch from contamination that could get into the interior of the lock body via the insertion channel. This also protects the switch from external damage or manipulation. Said transmission element, for example a pivotable element and / or a translationally movable element, ensures transmission of an actuation by the locking rod to the switch. The transmission element can be biased in the direction of an OFF position of the switch, for example by means of a compression spring.

The second closed position of the locking rod is advantageously located lower in the lock body than the first closed position with respect to an insertion direction of the locking rod into the lock body. In other words, in this embodiment, the locking bar is first brought into the first closed position, which can also be referred to as the unset closed position. Only when the locking bar is moved beyond the first closed position can the locking bar reach the second closed position, which can also be referred to as the arming closed position. As a result, the two-stage operation of the locking bar for the selection of the desired state of the alarm device is particularly clearly illustrated to the user.

According to an alternative embodiment, however, it is also possible for this sequence of the first closed position and the second closed position to be interchanged with respect to the insertion direction. According to a further alternative embodiment, it is also possible for two different receiving openings to be provided for inserting the locking rod into the lock body, for example lying next to one another or on opposite sides of the lock body, the locking rod assuming the first closed position when the locking rod passes through the one receiving opening has been inserted into the lock body, and wherein the locking rod assumes the second closed position when the locking rod has been inserted into the lock body through the other receiving opening.

• einen Beschleunigungssensor,
• eine Auswerte- und Steuerschaltung,
• einen akustischen und/oder optischen Signalgeber, und/oder
• eine Funksendeeinheit zum drahtlosen Aussenden eines Alarmsignals.

According to one embodiment, the alarm device comprises at least one (preferably several or all) of the following components:

• an electrical energy source for supplying energy to further components of the alarm device,
• an acceleration sensor,
• an evaluation and control circuit,
• an acoustic and / or visual signal generator, and / or
• a radio transmission unit for wireless transmission of an alarm signal.

The energy source can include one or more commercially available batteries and / or an electrical accumulator. If a rechargeable battery is provided, the articulated lock on the lock body can also have a power supply connection in order to be able to charge the battery.

As far as the acceleration sensor is concerned, it can be designed as a static acceleration sensor or as a dynamic acceleration sensor, wherein the static acceleration sensor can be designed as an inclination sensor for detecting an orientation and / or change of position and the dynamic acceleration sensor can be used for detecting a vibration.

The evaluation and control circuit can, for example, evaluate the signal of the detector mentioned for detecting the second closed position of the locking rod and, if appropriate, the respective signal of further detectors or switches. Furthermore, the evaluation and control circuit can also evaluate the signal of the aforementioned acceleration sensor, in order to trigger the output of an alarm signal, in particular when a change in position or vibration is detected during a monitoring operation.

The acoustic and / or optical signal transmitter can comprise, for example, a loudspeaker, in particular a piezo loudspeaker, and / or a light-emitting diode.

As an alternative or in addition to the output of an acoustic or optical alarm signal, the articulated lock can have a radio transmission unit for wireless transmission of an alarm signal, in particular to a radio reception unit of the authorized user. Such a radio reception unit can be a dedicated device assigned to the articulated lock (for example the radio remote control unit already mentioned) or a mobile phone. The signal can be transmitted according to a common standard (e.g. Bluetooth, WLAN, GSM).

According to one embodiment, the lock body has a housing with a storage chamber for the alarm device, the storage chamber having an alarm device mounting opening, and the locking rod at least partially blocking the alarm device mounting opening when the locking rod assumes the second closed position. Through the alarm device assembly opening At least one component of the alarm device (preferably the entire alarm device) can be inserted into the storage compartment, for example in the manufacture of the articulated lock or for replacing the battery (s). Since the locking bar is typically made of a particularly robust material, the locking bar can thus be used in a particularly simple manner to protect the alarm device in the storage chamber against manipulation from the outside in the second closed position, that is to say when the alarm device can be activated or activated ,

In this embodiment, the lock body can furthermore have a securing element which can be moved into a securing position by means of the locking rod when the locking rod is brought into the second closing position, the securing element at least partially blocking the alarm device mounting opening in the securing position. In other words, the security element can be used in addition to the locking rod to protect the alarm device in the storage chamber against manipulation from the outside. For this purpose, the securing element can, for example, partially engage in an opening (e.g. depression) in a housing of the lock body and partially cover the alarm device mounting opening. The securing element can be formed, for example, by a securing pin or a securing plate. The securing element can in particular be moved into the securing position by means of the tip of the locking rod.

According to a further embodiment, the lock body can have a sound outlet opening on at least two different sides, which communicates with the acoustic signal transmitter of the alarm device via a respective sound guide channel. A plurality of sound outlet openings on two or more sides of the lock body, for example two three or four sound outlet openings, can prevent or at least make it more difficult that in the case of a detected manipulation attempt, the output of the acoustic alarm signal is suppressed by closing a single sound outlet.

In this embodiment, it is preferred if the acoustic signal generator is arranged outside the alignment of the respective sound guide channel. In other words, the acoustic signal generator in this embodiment is not in the extension of the respective sound guide channel, but is laterally offset, so that the acoustic signal generator is not easily accessible from the outside and could be damaged, for example by inserting a pointed tool through the respective sound outlet opening.

According to one embodiment, the evaluation and control circuit is designed to allow a waiting interval and then a calibration interval to elapse before activating the alarm device before the evaluation and control circuit changes to monitoring mode. Furthermore, the evaluation and control circuit is designed to detect and store a position of the articulated lock by means of the acceleration sensor during the calibration interval, the evaluation and control circuit being further designed to repeatedly repeat a current position detected by the acceleration sensor during monitoring operation to compare the articulated lock with the stored position and to trigger an alarm signal if the comparison yields a predetermined minimum deviation. The waiting interval allows the authorized user to end the locking process without triggering an alarm signal.

In particular, a waiting interval is preferably also taken into account for triggering the alarm signal, so that the authorized user has enough time to take the lock and unlock it, in order to thereby deactivate the alarm device. Alternatively, only an acoustic one can be used initially and / or optical pre-alarm signal are output before the alarm signal is triggered after the waiting interval has elapsed.

For the activation of the alarm device, the evaluation and control circuit can also check whether the locking rod assumes the second closing position for a predetermined minimum period. In this way it can be prevented that an inadvertent briefly moving the locking bar into the second closed position unintentionally leads to activation of the alarm device.

The evaluation and control circuit is advantageously designed to deactivate the alarm device when the locking bar leaves the second closed position. This assumes that the locking bar has been unlocked first, i.e. the locking mechanism must be in an unlocked position. Leaving the second closed position can be detected by means of the same detector, which also detects the second closed position for activating the alarm device.

According to one embodiment, the lock body comprises a common housing for the locking mechanism and the alarm device, the common housing having a first chamber for the locking mechanism and a second chamber for the alarm device which is separate from the first chamber. This separation makes possible manipulation attempts more difficult and thus increases the security of the alarm device. The second chamber can in particular be the storage chamber for the alarm device already mentioned.

In this embodiment, the common housing can be formed by a single casting, for example made of hardened cast steel.

Furthermore, it is advantageous if the second chamber for the alarm device is arranged on the side of the first chamber facing away from the joint bar bracket. As a result, the first chamber with the locking mechanism located therein is protected in the lateral direction by the hinge rod bracket on the one hand and the second chamber on the other.

It is also preferred if the first chamber (for the locking mechanism), with the exception of a locking mechanism mounting opening, a key insertion opening (for inserting a key), an optional entry opening for inserting the locking rod (if a separate opening is provided for this), an optional passage opening for passing the locking rod into the second chamber (if a separate opening is provided for this) and optional fixing openings for inserting fixing elements (eg fixing pins) for fixing the locking mechanism. In particular, an at least substantially closed partition can be provided between the first chamber (for the locking mechanism) and the second chamber (for the alarm device). Through the locking mechanism assembly opening, the locking mechanism can be inserted into the first chamber when producing the articulated lock. In this embodiment, the locking bar can at least partially block the locking mechanism mounting opening when the locking bar is in the first closed position or the second closed position. Since the locking bar is typically made of a particularly robust material, the locking bar can thus be used in a particularly simple manner to protect the locking mechanism in the first chamber against manipulation from the outside while the locking bar is locked on the lock body.

According to one embodiment, the lock body has a latching device which is designed to hold the locking bar in a force-locking manner in the first closed position and / or in the second closed position.

For example, the latching device can have an elevation and a depression which are provided on a section of the lock body and on the locking rod and interact in an elastically engaging manner. In particular, the latching device can comprise an elastic section of a housing or a housing shell of the lock body, which interacts with a counter-section of the locking bar. The housing shell can be made of silicone, for example.

According to one embodiment (in particular also without the latching device mentioned), the hinge bar bracket can be folded into a folding rule configuration in which the hinge bars and the locking bar run parallel to one another. This enables space-saving transportation of the articulated lock. Here, the articulated bar bracket can preferably be brought into the folding rule configuration when the locking bar is in the first closed position. Alternatively or in addition to this, the articulated bar bracket can be brought into the folding rule configuration if the locking bar assumes an unlocked transport position (ie if the locking bar is not locked to the lock body). Furthermore, it is preferred if the articulated bar bracket cannot be brought into the folding rule configuration when the locking bar is in the second closed position. This prevents the user from transporting the articulated lock in the folded state in a particularly simple and effective manner (for example in the bag, quiver or holder mentioned at the beginning) and thereby accidentally activating the alarm device, which is due to changes in position and vibrations during transport or driving the two-wheeler would lead to an unwanted output of an alarm signal. Incorrect operation in this regard is thus prevented in that, on the one hand, the alarm device can only be activated in the second closed position of the locking bar and, on the other hand, the articulated bar bracket in this second closed position cannot be brought into the folding rule configuration, which is, however, a prerequisite for storage in a normal bag.

In order to enable a compact arrangement of the articulated lock, the longitudinal axes of the articulated rods and of the locking rod can run parallel to one another in one plane in the folding rule configuration of the articulated rod bracket. Furthermore, the lock body can extend along a longitudinal axis, the longitudinal axis of the lock body extending within a plane which, in the folding rule configuration of the hinge bar bracket, is spanned by the longitudinal axes of the hinge bars and the locking bar. Furthermore, in the ruler configuration of the hinge bar bracket, the lock body can be arranged within an extension plane of the hinge bar bracket, so that the lock body and the hinge bar bracket together form a flat package.

In an advantageous embodiment, the lock body has at least one receiving opening into which the locking rod projects in the first closed position and in the second closed position. In this case, the locking bar can preferably be inserted axially into the receiving opening of the lock body with respect to its longitudinal axis, a limitation of the receiving opening surrounding the locking bar circumferentially.

For locking the locking bar on the lock body, it is preferred if the locking bar of the hinge bar bracket has a locking section and the locking mechanism of the lock body has a bolt which, when the locking bar assumes the first closed position or the second closed position, can be brought into engagement with the locking section of the locking bar to lock the locking bar on the lock body. The locking section can be designed as a depression (in particular a blind hole), a through hole or a lateral recess.

Furthermore, the locking mechanism can have a locking cylinder and a driver which can be driven to rotate by a rotary actuation of the locking cylinder in order to bring about a locking movement and / or an unlocking movement of the bolt.

In this embodiment, the locking mechanism can in particular also have a conversion device which converts a rotary movement of the driver of the locking cylinder into a linear movement of the bolt, wherein the converter device can have, for example, an inclined surface on the driver and an inclined surface on the bolt which interact with one another ,

According to one embodiment, the bolt can be moved in both directions (locking and unlocking) by a corresponding actuation of the locking cylinder. As an alternative to this, an automatic function can be provided, the locking bar being automatically lockable on the lock body in the first closed position and / or the second closed position by insertion into the receiving opening of the lock body. In this case, the locking mechanism preferably comprises a pretensioning device which pretensions the bolt into the locking position, the bolt being temporarily movable out of the locking position into an unlocking position by incomplete insertion of the locking rod into the receiving opening of the lock body, and the pretensioning device for this purpose is adapted to move the bolt back into the locking position when the locking rod is inserted into the receiving opening up to the first closed position and / or the second closed position.

According to a modification, the invention further relates to an articulated lock with a lock body, which has a locking mechanism, and an articulated rod bracket, which has a plurality of articulated rods pivotally connected to one another and having a locking bar, a first end of the hinge bar bracket being permanently attached to the lock body and the locking bar forming a free second end of the hinge bar bracket, the locking bar being lockable on the lock body by means of the locking mechanism, the lock body further comprising an alarm device for emitting an alarm signal comprises, and wherein the alarm device can be activated by means of the locking rod when the locking rod assumes a closed position in which the locking rod is locked to the lock body.

As explained above, a detector for detecting the closed position of the locking rod can be provided for this. In particular, the lock body can have a switch (e.g. contact switch) which can be actuated by means of the locking rod when the locking rod is brought into the closed position. The switch can be actuated directly by means of the locking rod (in particular by means of the tip of the locking rod); or the switch can be confirmed indirectly via a transmission element. An evaluation and control circuit can evaluate the signal of the detector or switch. The other embodiments and features explained above can also be implemented analogously in this modification.

A possible embodiment of the invention is explained below by way of example only with reference to the drawings. The same or similar elements are identified therein with the same reference symbols.

Fig. 1

shows a schematic representation of an articulated lock in a first closed position of the locking bar.

Fig. 2

shows a schematic representation of an articulated lock in a second closed position of the locking rod.

This in Fig. 1 The articulated lock shown comprises a lock body 10 and an articulated bar bracket 40. The lock body 10 has a housing 20. The housing 20 forms a first chamber 21 for a locking mechanism 60 and a separate second chamber 22 for an alarm device 80. The first chamber 21 is accessible via a locking mechanism mounting opening 31, and the second chamber 22 is accessible via an alarm device mounting opening 32 , A passage opening 23 is provided between the first chamber 21 and the second chamber 22. The alarm device mounting opening 32 is closed by means of a chamber cover 34, although the chamber cover 34 can also be part of a removable inner housing (not shown) which fixes the various components of the alarm device 80 relative to one another. The housing 20 also has a receiving opening 24, a key insertion opening 26 and a support recess 28. The housing 20 is partially provided with an elastic housing sleeve 36, which covers the locking mechanism mounting opening 31 and there has a locking lug 38 pointing in the direction of the locking mechanism 60.

The hinge rod bracket 40 has a first end 41, which is permanently attached to the lock body 10, and a free second end 42, which can optionally be locked on the lock body 10. The joint rod bracket 40 takes in in Fig. 1 shown condition a so-called folding rule configuration. In the unlocked state of the articulated lock, the articulated bar bracket 40 can be unfolded from the folding rule configuration shown in order to form an open loop which can be placed around parts of a two-wheeler or another object. The free second end 42 of the hinge rod bracket 40 can then be inserted into the receiving opening 24 of the housing 20 and locked therein on the lock body 10 by means of the locking mechanism 60. As a result, the loop formed is closed and the two-wheeler is locked or secured to the object in question (for example a bicycle stand).

The articulated bar bracket 40 comprises a plurality of articulated bars 44 and (at the free second end 42) a locking bar 46. The articulated bars 44 and the locking bar 46 are each flat. The joint rods 44 and the locking rod 46 are articulated to one another in such a way that their joint axes 48 run parallel or coaxially to one another. The articulated rod bracket 40 can hereby be folded into a compact unit in the folding rule configuration shown, in which the articulated rods 44 and the locking rod 46 run parallel to one another in one plane. The locking bar 46 has a first locking recess 51 and a second locking recess 52 near its tip on the side facing the locking mechanism 60. Between the first locking recess 51 and the second locking recess 52, on the side facing away from the locking mechanism 60, the locking bar 46 has a locking recess 54. In addition, the locking bar 46 also has a latching shoulder 56.

The locking mechanism 60 located in the first chamber 21 of the housing 20 comprises a lock cylinder 62 accessible via the key insertion opening 26, into which a key 64 can be inserted in order to actuate the lock cylinder 62 by rotating the cylinder core and thereby a bolt coupled to the lock cylinder 62 66 to move in a straight line between a locking position and an unlocking position.

The alarm device 80 located in the second chamber 22 of the housing 20 comprises an electrical energy source 82 in the form of a battery for energy supply, an acceleration sensor 84, an evaluation and control circuit 86 and an acoustic signal generator 88 in the form of a piezo loudspeaker. The alarm device 80 further comprises a switch 92 which can be actuated via a transmission element 90 and which is connected to the evaluation and control circuit 86 in terms of signals. The switch 92 is in the embodiment shown here formed by a contact switch responsive to mechanical contact. A securing element 94 and a compression spring 96 for prestressing the transmission element 90 are also assigned to the transmission element 90.

In the in Fig. 1 In the state shown, the articulated lock is locked, the locking bar 46 being only partially inserted into the receiving opening 24 of the housing 20. In this position, the locking bar 46 is in a first closed position (disarmed closed position). By means of the key 64 inserted through the key insertion opening 26, the locking cylinder 62 can be rotated in order to lock the bolt 66 into the position shown in FIG Fig. 1 bring locking position shown, in which the bolt 66 engages in the first locking recess 51 of the locking bar 46 and thereby locks the locking bar 46 on the lock body 10. By turning the locking cylinder 62 in the opposite direction, the bolt 66 can be moved back into an unlocking position in which the bolt 66 releases the locking rod 46 for removal from the receiving opening 24 of the housing 20. In the first closed position of the locking bar 46, the locking bar 46 covers the locking mechanism mounting opening 31.

So that the user can easily feel the first closed position of the locking bar 46 when the locking bar 46 is inserted into the receiving opening 24, the locking lug 38 of the elastic housing shell 36 is arranged such that the locking lug 38 snaps into the locking recess 54 of the locking bar 46 as soon as the locking bar 46 occupies the first closed position. In the unlocked state, the locking bar 46 is held in the first closed position by the locking connection between the locking lug 38 and the locking recess 54, which facilitates handling when locking and unlocking.

The first closed position of the locking bar 46 according to Fig. 1 at the same time forms a transport position of the articulated rod bracket 40 for transporting the articulated lock. In the transport position, the articulated lock can be comfortably in one Storage device (eg bag, quiver or holder) are stored and carried, which encompasses the articulated bar bracket 40, which is compactly folded in the folding rule configuration.

In the in Fig. 1 The alarm device 80 cannot be activated in the first closed position of the locking bar 46 shown. This is only possible in a second closed position of the locking bar 46 and, in the exemplary embodiment shown, can in particular take place automatically, as follows using FIG Fig. 2 is explained.

Fig. 2 shows in one of the Fig. 1 corresponding representation, the articulated lock in a state in which the locking bar 46 is fully inserted into the receiving opening 24 of the lock body 10. In this position, the locking rod 46 is in the second closed position (arming-closed position), the tip of the locking rod 46 being guided through the passage opening 23 between the first chamber 21 and the second chamber 22 of the housing 20 and thus into the second chamber 22 protrudes. However, this complete insertion movement of the locking bar 46 into the receiving opening 24 is only possible if the hinge bar bracket 40 corresponds to the folding rule configuration Fig. 1 leaves. In Fig. 2 this can be seen from the fact that the four middle joint rods 44 rest on the lock body 10 in an oblique orientation, ie with respect to the illustration according to FIG Fig. 2 the four middle joint rods 44 are pivoted out of the plane of the paper. The articulated lock is locked in the second closed position in an analogous manner to the first closed position, whereby by actuating the locking cylinder 62 the bolt 66 is brought into the locking position in which the bolt 66 engages in the second locking recess 52 of the locking rod 46 and the locking rod 46 thereby locked on the lock body 10.

In the second closed position of the locking bar 46, the alarm device 80 is activated by means of the locking bar 46, which allows the alarm device 80 to be armed automatically in a simple manner. To detect the second closed position of the locking bar 46, the readout and control circuit 86 is connected to the switch 92, which is actuated indirectly via the transmission element 90 by the tip of the locking bar 46 as soon as the locking bar 46 is brought into the second closed position. By interposing the transmission element 90, which is designed, for example, as a linearly movable, laterally projecting actuating arm, the switch 92 can be arranged outside the alignment of the receiving opening 24 of the lock body 10, as a result of which the switch 92 can be better protected against contamination, damage or manipulation ,

The securing element 94, which is pin-shaped in the exemplary embodiment shown here and is surrounded by the compression spring 96, is connected to the movable transmission element 90. In the second closed position of the locking rod 46, the securing element 94 together with the transmission element 90 is moved against the bias of the compression spring 96 into a securing position in which the securing element 94 engages in the support recess 28 of the housing 20. In the second closed position of the locking bar 46 according to Fig. 2 The locking bar 46 and the securing element 94 each partially block the alarm device mounting opening 32 of the housing 20 in order to protect the alarm device 80 against manipulation from outside, the securing element 94 being supported in the support recess 28 of the housing 20.

In the second closed position of the locking bar 46 according to Fig. 2 engages behind the locking lug 38 of the elastic housing sleeve 36 the locking shoulder 56 of the locking bar 46, so that a locking lock is again formed, which also ensures in the unlocked state that the locking bar 46 is secured against unintentional slipping out.

After the articulated lock has been brought into the second closed position and the switch 92 has been actuated by the locking rod 46 via the transmission element 90, the evaluation and control circuit 86 first allows a waiting interval and then a calibration interval to elapse before it goes into a monitoring mode. During the calibration interval, the position of the joint lock (orientation relative to gravity) is detected and stored by means of the inclination and vibration-sensitive acceleration sensor 84. In the subsequent monitoring mode, the evaluation and control circuit 86 then repeatedly compares a current position of the articulated lock, respectively detected by means of the acceleration sensor 84, with the stored position and triggers an alarm signal if the comparison exceeds a predetermined minimum deviation. The waiting interval enables the user to end the locking process without triggering an alarm signal.

The acoustic alarm signal generated in the event of an alarm by means of the acoustic signal generator 88 is conducted between the first chamber 21 and the second chamber 22 of the housing 20 and can leave the housing 20 via several sound outlet openings (not shown) on different sides of the housing 20. Since the acoustic signal generator 88 is hidden in the interior of the lock body 10 by this design, it cannot be manipulated itself, which further increases the security of the alarm device 80.

The output of such an alarm signal can only be stopped by the authorized user. For this purpose, it is necessary to first unlock the locking bar 46 by actuating the locking cylinder 62 by means of the key 64 and then pull the locking bar 46 out of the lock body 10 a little, as a result of which the transmission element 90, which is biased by the compression spring 96, loses contact with the switch 92 (OFF Position of the switch 92) and the readout and control circuit 86 prevents the output of the alarm signal. The Alarm device 80 can therefore only be deactivated when the locking cylinder 62 is unlocked. In this state, the hinge bar bracket 40 can be returned to the folding rule configuration for transport, and the locking bar 46 can be locked in the first closed position for transport.
