Description

Technical Field

[0001] This application relates to a brake disc lock with a pawl, the pawl comprising a first pawl portion and a second pawl portion. The first pawl portion and the second pawl portion are movable relative to each other between an open position and a closed position. In the closed position, the pawl includes a predetermined clear width to engage a portion of the brake disc of a two-wheeled vehicle. Additionally, the pawl includes a locking mechanism configured to lock the pawl in the closed position. Background Technology

[0002] A brake disc lock is used to protect a two-wheeled vehicle from any unauthorized departure, where the brake disc of the two-wheeled vehicle is prevented from rotating. For this purpose, the brake disc lock may engage in an opening formed in the brake disc, for ventilation / cooling purposes or for weight reduction.

[0003] Such brake disc locks may include, for example, a receiving gap to accommodate the brake disc, and this receiving gap is then penetrated laterally by a latch to secure the brake disc lock to the brake disc. Operation of such brake disc locks can be unpleasantly cumbersome. In particular, two hands are required when the receiving gap of the brake disc lock needs to be aligned relative to the brake disc with one hand so that the locking device can be operated with the other hand to bring the latch into contact with the corresponding opening on the brake disc. Another known disadvantage of brake disc locks is that a fixed, predetermined depth of the receiving gap can result in an undesirable large gap between the brake disc lock and the brake disc in the closed position, which can lead to a loose fit of the brake disc lock at the brake disc. Ratchet-type brake disc locks may present similar problems if the user does not close the latch pawls sufficiently in the changing position and if unnecessarily large gaps are left between the pawls and the brake disc due to improper use. Summary of the Invention

[0004] One object of this application is to manufacture a brake disc lock that allows for simple and fault-proof operation and ensures a secure fit of the brake disc lock on a variety of brake discs.

[0005] This objective is achieved by a brake disc lock having the features of claim 1.

[0006] In the brake disc lock according to this application, in the closed position, the pawl has a predetermined clear width to engage a portion of the brake disc of a two-wheeled vehicle. In this closed position with the predetermined clear width, the pawl can be locked. The brake disc lock also includes an adjusting device configured to adjust the predetermined clear width of the pawl to different brake discs.

[0007] The relevant portion of the brake disc may be surrounded by claws, with one of the two claw portions engaging in an opening in the brake disc, and the other of the two claw portions engaging around the outer circumference of the brake disc, or engaging in another opening in the brake disc. In the closed position, the claws thus form a receiving space for the relevant portion of the brake disc. At this point, the net width of the claw specifies the effective internal dimension of the claw in its closed position. The net width of the claw should generally correspond as closely as possible to the extent of the surrounding portion of the brake disc; that is, the claw should be installed onto the portion of the brake disc with a small clearance, such that the brake disc is securely locked onto the brake disc.

[0008] Therefore, the net width of the pawl effectively limiting the accommodating space of the brake disc in the closed position is adjustable, i.e., a predetermined net width for subsequent use of the brake disc lock, and a net width maintained for subsequent use. Thus, by means of an adjustment device, the net width of the pawl for subsequent use of the brake disc lock can be adjusted to the size of a particular brake disc, particularly to the range of the circumferential portion of the brake disc. Therefore, this adjustment of the predetermined net width of the pawl relates to the subsequent re-locking and release of the brake disc lock at the brake disc in question.

[0009] In particular, due to the structure of the brake disc lock, it can be used in various vehicles with at least two wheels, such as motorcycles, scooters, E-bikes, cargo bicycles, bicycles, trailers, four-wheeled bicycles, etc. Specifically, due to the adjustability of the predetermined net width of the pawls, it prevents the brake disc lock from being released from the brake disc, even by slight bending, for example, because the ends of the two pawl portions are too far apart. Furthermore, it prevents prying tools (e.g., levers) from being inserted into the gap between the brake disc and the brake disc lock due to excessive clearance, or at least makes inserting a prying tool more difficult.

[0010] Another advantage of this application is its ease of operation and fault-proof design. Since locking only occurs in the closed position of the pawl, the predetermined clear width of the pawl is always maintained. Therefore, by fully encircling the pawl with a very small gap in the closed position, reliable mounting of the pawl to the brake disc is ensured without requiring the user to ensure the pawl is always closed with maximum possible lift. Due to the shape of the pawl, the brake disc lock can be suspended on the brake disc in the open position. This means it can be operated with one hand, as the brake disc lock does not need to be held and aligned relative to the brake disc for locking.

[0011] Other embodiments of this application are described below and in the dependent claims.

[0012] In some embodiments, at least when the brake disc lock is in use, the locking mechanism is fixedly connected to the first pawl portion. The second pawl portion is movable relative to the first pawl portion and the locking mechanism to move the pawl between an open position and a closed position. In some embodiments, the brake disc lock may also include a lock body in which the locking mechanism is held, and the second pawl portion is movably supported on the lock body. In this respect, the first pawl portion may also be referred to as a retaining portion, and the second pawl portion may be referred to as a locking portion.

[0013] In some implementations, the first claw portion and the second claw portion can move linearly relative to each other between the open position and the closed position, that is, move in a straight line.

[0014] In some embodiments, the first and second claw portions may include corresponding hook structures to engage around that portion of the brake disc. In particular, the claws may be configured in a generally C-shape.

[0015] To allow for the adjustment of the predetermined net width of the claw, various possibilities are possible, which will be explained below.

[0016] In some embodiments, at least one of the pawl portions may include a hook structure configured to partially engage around the brake disc, and when the pawl is closed and locked, the hook structure occupies an effective distance from the locking mechanism (and thus, specifically, an effective distance from the lock body of the brake disc lock). An adjustment device may be configured to adjust the effective distance of the hook structure from the locking mechanism or to the lock body. In particular, the effective distance may be related to the direction of movement of the pawl. In such embodiments, in particular, the mounting position of the retaining portion of the pawl may be adjustable, or the length of the retaining portion or the locking portion of the pawl may be adjustable.

[0017] In some embodiments, when the brake disc lock is in use, the first pawl portion may be mounted in an adjustable fixed position relative to the locking mechanism. The adjustment device may be configured to adjust the mounting position of the first pawl portion relative to the locking mechanism. This mounting position may be the position occupied by the first pawl portion at the locking mechanism during subsequent use of the brake disc lock for re-locking and releasing from the relevant brake disc, and for being maintained during use, particularly during movement of the pawl between the open and closed positions.

[0018] In such an embodiment, the brake disc lock may include a retainer supporting the locking mechanism, wherein a first pawl portion may be mounted on the retainer. Specifically, the retainer may be formed from the lock body.

[0019] In some embodiments, the adjustment device can be configured to adjust the predetermined net width of the pawls based on a form-fit connection between two components of the brake disc lock (e.g., between the pawl portion and the locking mechanism, or between the two pawl portions), according to a predetermined engagement pitch. Due to the form fit, a particularly high level of security is achieved in the adjustable connection to prevent any attempt to open it. The predetermined engagement pitch of the form-fit connection simplifies the user's adjustment of the net width.

[0020] In one possible implementation, the adjustment device may include an engagement profile (e.g., serrations) associated with the locking mechanism and an engagement-opposite profile (e.g., opposing serrations) associated with the first pawl portion. The engagement profile and engagement-opposite profile may engage with each other in different mounting positions and may be fixed to each other in corresponding mounting positions. Thus, different mounting positions can be used to adjust a predetermined net width of the pawl in the closed position for subsequent use of the brake disc lock. The engagement profile need not be formed directly at the locking mechanism, but may be provided, for example, at the retainer or the lock body of the brake disc lock. The engagement profile and engagement-opposite profile may include multiple teeth, which are, for example, tapered, particularly serrated, or rectangular in cross-section, allowing for incremental adjustment. Fixation at the various mounting positions may be specifically achieved by fixing elements, which will be described in more detail below.

[0021] As an alternative to a serrated engagement profile and a relatively serrated engagement profile, the adjusting device may, for example, include a row of holes for screw fasteners according to a predetermined engagement pitch, wherein, for example, threaded holes may be aligned with one of a plurality of through holes, or through holes may be aligned with one of a plurality of threaded holes, and wherein a corresponding threaded hole on one side and a corresponding through hole on the other side are associated with a locking mechanism or a first claw portion, or vice versa, i.e., the locking mechanism and the first claw portion are associated with a corresponding threaded hole on one side and a corresponding through hole on the other side.

[0022] In this embodiment with a fixed mounting position having an adjustable first claw portion, the first claw portion may be rigidly formed and / or have a fixed length. Specifically, the first claw portion may correspond to the retaining portion of the claw.

[0023] In other embodiments for adjusting the predetermined net width of the claw, at least one claw portion including the hook structure may include a locking structure, with a locking mechanism engaging the locking structure when the claw is closed and locked. The adjusting device may be configured to adjust the effective length between the hook structure and the locking structure of the claw portion. In this embodiment, the claw portion in question may be movable relative to another claw portion and / or relative to the locking mechanism (or lock body) to move the claw between an open position and a closed position. Thus, in particular, the claw portion in question may correspond to the locking portion of the claw, in which, in this embodiment, the length of the locking portion is adjustable.

[0024] In other embodiments for adjusting the predetermined net width of the pawl, the brake disc lock may include a retainer supporting the locking mechanism, wherein at least one pawl portion, including a hook structure, has a connecting end at which the pawl portion is connected to the retainer in a fixed position (either integrally formed as one piece or permanently connected as multiple pieces). The adjustment device may be configured to adjust the effective length between the connecting end of the hook structure and the pawl portion. Specifically, the retainer may be formed from the lock body. In this embodiment, the pawl portion in question may be arranged to be immovable when the pawl moves between an open position and a closed position. Specifically, the pawl portion in question may correspond to the retaining portion of the pawl, in which the length of the retaining portion of the pawl is adjustable.

[0025] In this embodiment with a length-adjustable (first or second) claw portion, the adjustment device may, for example, include a threaded rod and an internal thread movable along the threaded rod, through which the effective length of at least one claw portion is adjustable. The effective length can be achieved by rotating the threaded rod and the internal thread relative to each other in small increments. The threaded rod may be connected to a hook structure, and the internal thread may be connected to a locking structure or the mounting end of the claw portion, and vice versa; that is, the threaded rod may be connected to the mounting end of the locking structure or the claw portion, and the internal thread may be connected to the hook structure. Thus, the adjustment device (having a threaded rod and an internal thread) may be part of the length-adjustable claw portion.

[0026] In some implementations, the brake disc lock can be configured such that the adjustment device can be actuated only as a result of unlocking the locking mechanism to adjust the predetermined net width of the pawl to different brake discs. Therefore, an authorized user must first unlock the brake disc lock or locking mechanism via an associated identification device (e.g., by key, or by entering or sending a code, particularly by radio). For example, the adjustment device can only be actuated after the brake disc lock has been successfully unlocked, because the adjustment device is only accessible when the pawl is in the open position or when the brake disc lock is released from the brake disc, as will be explained below. By doing so, the brake disc lock is prevented from being released from the brake disc by manipulating the adjustment device.

[0027] In some embodiments, the adjusting device may include a fixing element configured to adjust the predetermined net width of the pawl (i.e., the adjustment value). The fixing element may be partially covered by a brake disc or brake disc lock, and / or may prevent movement of the fixing element when the brake disc lock is mounted on the brake disc and when the pawl is closed and locked. The fixing element may include, for example, at least one screw or nut for fixing the position of another element of the adjusting device, wherein the screw or nut is fixed by the pawl itself without any displacement when the pawl is in the closed position. Alternatively, the fixing element may be, for example, a metal pin for fixing to prevent displacement.

[0028] In some implementations, the pawl may be biased toward the open position. This bias can be achieved using a coil spring, torsion spring, or wave spring. Due to this bias, the pawl automatically moves to the open position after unlocking, making it easily identifiable to the user when the pawl is in the open position. Additionally, this bias ensures stability in the open position. This simplifies applying the brake disc lock to the brake disc (particularly in the explained mounting) and / or one-handed operation.

[0029] In some embodiments, the locking mechanism may include a latch that, when the pawl is closed, locks the second pawl portion to the first pawl portion in a locked position, and releases the second pawl portion to move relative to the first pawl portion in a released position. The locking mechanism may include a locking cylinder to actuate the latch.

[0030] In such an implementation, the latch can be biased toward the locking position, wherein the latch is configured to first be moved from the open position to the closed position by a pawl and then pushed back toward the release position, and then snapped into the locking position due to the bias. The biasing of the latch can be achieved, for example, by a helical spring or torsion spring, one end of which engages with the latch, while the other end is supported at the housing of the locking mechanism and / or the lock body. This bias enables automatic locking of the disc brake lock, eliminating the need for manual operation of the locking cylinder. This further simplifies the aforementioned one-handed operation of the disc brake lock.

[0031] In this embodiment with automatic locking, the latch is rotatably mounted and has a circumferential surface with a tangential groove, wherein the groove releases the locking protrusion of the second pawl portion in the latch's released position. Thus, the latch can be configured as a rotary latch, which is, for example, rotatably mounted on the circumferential surface of the locking cylinder. The axis of rotation of the rotary latch can be aligned with the axis of rotation of the locking cylinder.

[0032] As an alternative to a purely mechanical locking mechanism (with a locking cylinder), an electromechanical locking mechanism can also be provided, for example, with an electric motor or electromagnet as an electronically controlled actuator.

[0033] To simplify one-handed operation of the brake disc lock, at least one pawl portion, particularly the first pawl portion, can be configured to engage in an opening in the brake disc, thereby keeping the brake disc lock suspended on the brake disc. Thus, also in the open position of the pawl, the brake disc lock can be arranged to hang freely on the brake disc without the user needing to hold and position the brake disc lock with one hand, allowing the locking mechanism to be actuated with the other hand. For this purpose, in particular, the hook structure already mentioned can be formed at the pawl portion in question.

[0034] In some embodiments, the brake disc lock may include an alarm device for outputting an alarm signal, wherein the alarm device is configured to be actuated by moving the pawl to a closed position and deactivated by moving the pawl from the closed position to an open position. Thus, it is possible to automatically actuate and deactivate the alarm device, particularly due to the unlocking operation of the locking mechanism, when the user moves the pawl between the closed and open positions.

[0035] The alarm device may include a motion sensor that detects changes in position and / or acceleration or changes in acceleration. For example, when a threshold is exceeded, the change in position and / or acceleration or changes in acceleration trigger the output of an alarm signal. The acceleration sensor may also output an audible alarm signal to authorized users as a reminder to prevent them from forgetting to release the brake disc lock when moving the two-wheeled vehicle. Additionally, when the alarm device is activated, a short actuation tone may be emitted to acoustically confirm the activation of the alarm function.

[0036] In some embodiments, the alarm device may include an actuation switch configured to be automatically actuated by the second pawl portion or by a portion of the brake disc lock connected to the second pawl portion when the pawl is in the closed position. Specifically, the actuation switch may be configured as a contact switch. For example, actuation of the alarm device may be triggered by an actuation ramp interacting with the second pawl portion and the alarm device. In the open position of the pawl, if the actuation switch is no longer actuated, this triggers deactivation of the alarm device.

[0037] The evaluation of the signals from the motion sensor and / or the actuation switch can be performed by the control circuitry of the alarm device.

[0038] In such an implementation, the alarm device may be arranged within the housing portion of the brake disc lock, which is fixedly connected to the first pawl portion, wherein the alarm device is accessible only as a result of unlocking the locking mechanism. This ensures that the alarm device is accessible only to authorized users with an identification device (e.g., a key) associated with the locking mechanism (e.g., for battery replacement).

[0039] Specifically, the housing portion of the brake disc lock may include an access opening through which the alarm device can be accessed. For example, the brake disc lock may be configured such that, in the closed position of the pawl, the access opening is covered by a second pawl portion. Conversely, in the open position of the pawl, the access opening is exposed for access. In other embodiments, the access opening may be covered, for example, by a cover that can only be opened when the brake disc lock is in the unlocked state. In this way, the inherent protection of the alarm device is ensured against any attempt to tamper with the alarm device.

[0040] In some embodiments with additional securing functions, the brake disc lock may include a first securing portion associated with a first pawl portion and a second securing portion associated with a second pawl portion. In the open position of the pawls, the first and second securing portions may form receiving openings for inserting eyelets of flexible fasteners, particularly chains. In the closed position of the pawls, the first and second securing portions may form circumferentially closed boundaries of the receiving openings to secure the inserted eyelets to the brake disc lock. For example, one of the two securing portions may be formed by a portion of the lock body of the brake disc lock. Thus, the brake disc lock can be used not only to stop the brake disc of a two-wheeled vehicle, but also to secure the two-wheeled vehicle to surrounding objects and / or to other objects (e.g., helmets) attached to the two-wheeled vehicle.

[0047] Figure 3 A perspective view of components of an alternative embodiment of a brake disc lock with a threaded rod is shown. Detailed Implementation

[0048] Figure 1AA perspective view of the rear side of a brake disc lock 100 in the closed position is shown. The brake disc lock 100 includes a lock body 114 and a pawl 102, the pawl 102 having a first pawl portion 104 and a second pawl portion 106. As will be further explained below, in the use state of the brake disc lock 100, the first pawl portion 104 is immovably held at the lock body 114, and the second pawl portion 106 is movably guided on the lock body 114, and the second pawl portion 106 can be locked in the closed position of the pawl 102. The first pawl portion 104 and the second pawl portion 106 form respective hook structures 105 and 107 at their free ends. The lock body 114 may be formed by a metal casting (e.g., a zinc die casting). The first pawl portion 104 and the second pawl portion 106 may be formed by stamping and bending metal parts.

[0049] The brake disc lock 100 includes a first fixing portion 120 and a second fixing portion 122. The first fixing portion 120 is associated with a first claw portion 104 and is formed by a portion of the lock body 114. The second fixing portion 122 is formed by a portion of the second claw portion 106. In the open position of the claw 102, the first fixing portion 120 and the second fixing portion 122 form a receiving opening 123 for inserting a hole for a flexible fixing member 124. In the closed position of the claw 102, the first fixing portion 120 and the second fixing portion 122 form a circumferential closed boundary of the receiving opening 123 to secure the inserted hole at the brake disc lock 100.

[0050] Figure 1B A perspective view of a brake disc lock 100 without lock body 114 is shown with pawl 102 in the closed position. The brake disc lock 100 includes a locking mechanism 108 comprising a locking cylinder 126 located within a two-piece lock cylinder housing 125 and configured to lock pawl 102 in the closed position. For this purpose, the locking mechanism 108 includes a rotary latch 202, as if combined... Figure 2A and Figure 2B Further explanation: The locking mechanism 108 is arranged within the lock body 114, which in this respect serves as a retainer that holds the locking mechanism 108 and the first claw portion 104, and supports the movable second claw portion 106.

[0051] The brake disc lock 100 also includes an alarm device 110, which is disposed in the housing portion 132 of the brake disc lock 100. Figure 1C The alarm device 110 includes a housing 134, an actuation switch 112, a motion sensor (not shown), a control circuit (not shown), and an audio signal generator 113. Figure 1B ).

[0052] Additionally, cover 118 is configured to cover the open rear side of lock body 114, thereby covering locking mechanism 108 and alarm device 110. Figure 1C The image shows cover 118 being removed from its original position.

[0053] With the pawl 102 in the open position, the brake disc lock 100 can be mounted to the brake disc of a two-wheeled vehicle (not shown) by inserting the hook structure 105 of the first pawl portion 104 into the opening of the brake disc to partially engage around the brake disc. For this purpose, the brake disc lock 100 is arranged in a plane parallel to the extension plane of the brake disc, such that when the brake disc lock 100 is released, the brake disc is supported at a first support point 116 of the first pawl portion 104 and a second support point 130 of the lock body 114. This is achieved by moving the pawl 102 from the open position to... Figure 1A and Figure 1B In the closed position shown, the brake disc lock 100 is locked and secured to the brake disc. This is achieved by moving the second claw portion 106 of the claw 102 along the direction of the first claw portion 104 and the lock body 114, which will be explained in more detail below.

[0054] Figure 2A and Figure 2B Cross-sectional views (excluding lock body 114) of the brake disc lock 100 in the closed and open positions are shown in a top view. The claw portions 104 and 106 are movable relative to each other between the open and closed positions of claw 102. Figure 2A In the closed position shown, the pawl 102 has a predetermined net width for partial engagement around the brake disc of the two-wheeled vehicle. The net width of the pawl 102 represents the internal dimensions of the pawl 102 in its closed position, specifically, on one hand, the distance between the first support point 116 of the first pawl portion 104 and the second support point 130 of the lock body 114, and on the other hand, the distance between the first support point 116 of the first pawl portion 104 and the third support point 212 of the second pawl portion 106. In this exemplary embodiment, in the closed position of the pawl 102, the second support point 130 of the lock body 114 ( Figure 1A ) and the third support point 212 of the second claw part 106 Figure 2A They are arranged at approximately the same height. However, in conjunction with this application, the net width of the claw 102 may also refer to the internal dimension or distance between the ends of the two claw portions 104, 106.

[0055] In the operational state of the brake disc lock 100, the first claw portion 104 of the claw 102 is mounted in an adjustable fixed position relative to the lock body 114 and thus relative to the locking mechanism 108 and the aforementioned rotary latch 202. The adjustment device 217 of the brake disc lock 100 is configured to adjust the mounting position of the first claw portion 104 relative to the locking mechanism 108 for different brake discs. The adjustment device 217 can be configured to have an engagement profile and an engagement relative profile, the engagement profile being associated with the lock body 114 or the locking mechanism 108 in the form of serrations 218, and the engagement relative profile being associated with the first claw portion 104 in the form of relative serrations 220. The serrations 218 and the relative serrations 220 can engage and fix each other in different mounting positions. The serrations 218 associated with the locking mechanism 108 can be mounted on the side of the lock body 114 facing the first claw portion 104. The relative serrations 220 associated with the first claw portion 104 can be mounted on the side of the first claw portion 104 facing the lock body 114. The saw teeth 218 and the opposing saw teeth 220 can be fixed to each other by a fixing element, which is configured here as, for example, two fixing screws 214, to fix the mounting position of the first claw portion 104.

[0056] Therefore, the adjusting device 217 is configured to adjust the predetermined net width of the pawl 102 to different brake discs. For this purpose, the fixing screw 214 can be loosened in the open position of the pawl 102. Figure 2B This allows the releasable serration 218 and the opposing serration 220 to engage with each other. The net width of the claw 102 can be adjusted by moving the first claw portion 104 to the desired position. Once the desired position is reached, the serration 218 and the opposing serration 220 can re-engage and be secured to each other by the retaining screw 214.

[0057] exist Figure 1C The image shows two retaining screws 214 disengaged from their original positions. To secure the serrations 218 and 220, once the serrations 218 and 220 are engaged in the desired mounting position on the first claw portion 104, the retaining screws 214 are each inserted into the threaded holes 136 of the lock body 114. By rotating the retaining screws 214 clockwise, the first claw portion 104, and thus the 220, press against the serrations 218 and secure them to each other.

[0058] The first pawl portion 104 is thus adjusted to occupy the position of the brake disc lock 100 for subsequent use, for repeated locking and releasing of the brake disc in question relative to the lock body 114 and therefore relative to the locking mechanism 108, and for being held during use, particularly during the movement of the pawl 102 between the open and closed positions.

[0059] The operation of the locking mechanism 108 will be explained in more detail below. A rotary latch 202, operable by means of the locking cylinder 126, is configured to lock the pawl 102 in the closed position. Figure 2A The rotary latch 202 is biased, for example, by a torsion spring (not shown) in the direction of its locked position. According to... Figure 2A and 2B The offset is counterclockwise oriented. A rotary latch 202 is rotatably mounted on the circumferential surface 222 of the locking cylinder 126, wherein the axis of rotation of the rotary latch 202 coincides with the axis of rotation of the locking cylinder 126. The rotary latch 202 includes a tangential groove 208 on the outer cylindrical circumferential surface 222.

[0060] By moving the pawl 102, particularly the second pawl portion 106, from the open position to the closed position, the biased rotary latch 202 is temporarily pushed back toward the release position by a locking structure in the form of a locking protrusion 204 on the second pawl portion 106. For this purpose, the locking protrusion 204 engages with the boundary of the tangential groove 208 of the rotary latch 202. Once the locking protrusion 204 has pushed the rotary latch 202 back toward the release position to the extent that the tangential groove 208 extends substantially parallel to the direction of movement of the locking protrusion 204, further movement of the locking protrusion 204 toward the release position releases the contact between the locking protrusion 204 and the boundary of the tangential groove 208, and the rotary latch 202 can spring back to the locked position due to its bias. Thus, the pawl 102, particularly the second pawl portion 106, is locked in the closed position because the rotational latch 202 now prevents the locking protrusion 204 from retracting toward the open position. The locking mechanism 108 is only unlocked by operating the lock cylinder 126 with the associated key, that is, by moving the rotating bolt 202 from the locked position to the released position. The movement path of the locking protrusion 204 toward the open position of the release pawl 102 is unlocked, wherein the tangential groove 208 is oriented in the released position of the rotating bolt 202 and its axis is parallel to the movement direction of the locking protrusion 204.

[0061] The brake disc lock 100 includes a return spring 206 mounted as a coil spring between the second pawl portion 106 and the cover 118. When the brake disc lock 100 or pawl 102 is closed, the return spring 206 is biased as the second pawl portion 106 moves toward the first pawl portion 104. When the brake disc lock 100 is unlocked by actuating the lock cylinder 126 with the associated key, the second pawl portion 106 is pushed from the closed position of the pawl 102 to the open position by the return spring 206.

[0062] The alarm device 110 of the brake disc lock 100 can be actuated when the pawl 102 is moved from the open position to the closed position, and deactivated when the pawl 102 is moved from the closed position to the open position. For this purpose, once the pawl 102 moves from the open position to the closed position, the actuation protrusion 216 of the second pawl portion 106 can actuate the actuation switch 112 of the alarm device 110, which is configured as a contact switch. The actuation protrusion 216 can actuate the actuation switch 112 directly or indirectly. In the case of indirect actuation, as provided in the illustrated embodiment, the actuation protrusion 216 can press the movable housing 134 of the alarm device 110 against the lock body 114, thereby actuating the actuation switch 112 of the alarm device 110. The alarm device 110 is actuated as long as the pawl 102 is in the closed position.

[0063] As described above, by unlocking the brake disc lock 100, the second pawl portion 106 is pushed back to the open position of the pawl 102 by the return spring 206. As a result, the actuation switch 112 of the alarm device 110 is de-actuated. In the case of direct actuation, this can be done by releasing the actuation protrusion 216 from the actuation switch 112, or in the case of indirect actuation as shown, this can be done by pushing the second pawl portion 106 and thus the actuation protrusion 216 back to the open position of the pawl 102, and the housing 134 of the alarm device 110 can yield back to its original position. As a result, the housing 134 of the alarm device 110 will not press further against the lock body 114, and the actuation switch 112 will be de-actuated. The reset of the housing 134 of the alarm device 110 can occur due to a restoring force, which is generated, for example, by compression of the silicone layer between the housing 134 of the alarm device 110 and the lock body 114 based on the contact pressure from the actuation protrusion 216.

[0064] Figure 3 A perspective view of an alternative embodiment of a brake disc lock 100 is shown, which has a first claw portion 304 and a second claw portion 306 of a claw 302; it also has a locking mechanism 308 and an alarm device 310. The first claw portion 304 includes a hook structure 305 and is fixedly connected to the locking mechanism 308. The second claw portion 306 includes a hook structure 307 at one end and a threaded rod 312 with a locking structure 309 at the other end, which forms a block-like thickening. When the claw 302 is in the closed position shown, the locking structure 309 of the second claw portion 306 can be locked by the locking mechanism 308, similar to a combination. Figure 2A and 2BThe adjusting device 317 includes a threaded rod 312 and an internal thread 313 of a hook structure 307 of the second pawl portion 306, which is movable along the threaded rod 312. The adjusting device 317 allows the effective length of the second pawl portion 306 to be adapted to different brake disc sizes. The position of the hook structure 307 at the threaded rod 312, and thus the effective length of the second pawl portion 306, can be fixed by a fixing element 314, which is configured here as a nut. For this purpose, the fixing element 314 is fixed by form-fit to prevent rotation in the closed position of the brake disc lock 100, wherein the fixing element 314 is received in a form-fit manner within the lock body (…). Figure 3 (Not shown in the image). In the open position of the brake disc lock 100, the form fit of the retaining element 314 is released, and the effective length of the second pawl portion 306 can be adjusted by rotating the threaded rod 312 in small increments (depending on the thread pitch).
