Abstract

A frame lock for a two-wheeler comprises a lock body, a rotary lock ring, a main lock bolt, a locking device, a lock tongue bolt and a spring. The lock body has a lock cylinder receiver, a lock tongue receiver and a rotary lock ring receiver. The rotary lock ring is accommodated in the rotary lock ring receiver and is adjustable between an open position and a closed position. The main lock bolt is laterally linearly adjustable between a locked position and an unlocked position. The locking device is accommodated in the lock cylinder receiver and has a clutch by which the locking device is coupled to the main lock bolt such that the main lock bolt is adjustable to its unlocked position by the locking device via the clutch. The lock tongue bolt is laterally linearly adjustable between a locked position and an unlocked position. The spring pre-tensions the lock tongue bolt in the direction of its locked position. In this regard, a coupling of the main lock bolt and a coupling of the lock tongue bolt are coupled to each other such that on the one hand the lock tongue bolt is adjustable to its unlocked position by the locking device via the main lock bolt and on the other hand the main lock bolt is pre-tensioned in the direction of its locked position by the spring via the lock tongue bolt.

Description

Technical Field

[0001] This invention relates to frame locks for two-wheeled vehicles. Background Technology

[0002] Frame locks differ from portable two-wheeler locks in that they are typically fixed and usually permanently attached to the frame of the two-wheeler, for example, screwed onto the frame. In this respect, frame locks are arranged such that the hook of the frame lock can be selectively adjusted to a position where the frame lock engages between the spokes of the two-wheeler's wheels, thereby preventing the two-wheeler from moving. The hook is conveniently secured in this position by a latch of the frame lock, which can be adjusted at least in surface contact by the lock cylinder or another locking device of the frame lock, where the user must have a combination (such as a key) to actuate the lock cylinder or the other locking device. Typical designs of the hook are, on the one hand, a pivot hook configuration with a straight path, and on the other hand, a rotary hook configuration with an arcuate path.

[0003] Specifically, a frame lock for a two-wheeled vehicle may include a lock body and a rotating locking ring, wherein the rotating locking ring extends along a circular path and is adjustable relative to the lock body along the circular path between an open position and a closed position, the rotating locking ring releasing the wheels of the two-wheeled vehicle for rotation in the open position, and the rotating locking ring preventing the wheels from rotating in the closed position. In this respect, the frame lock may also include a latch adjustable between an unlocked position and a locked position, wherein when the rotating locking ring is in its closed position and the latch is in its locked position, the latch prevents the rotating locking ring from being adjusted to the open position.

[0004] When the frame lock is in the closed state, that is, when the rotary lock ring is in its closed position, the wheel of the two-wheeled vehicle equipped with the frame lock is prevented from rotating, thereby preventing the two-wheeled vehicle from moving. However, due to the rotary lock ring, the two-wheeled vehicle is generally not fixed in a specific position, that is, it is prevented from being moved from that position in a way other than riding (e.g., taking it away). Also for the safety of the two-wheeled vehicle in this respect, a safety chain, safety rope, or other safety element (especially a long rope-like safety element) that can be securely connected to the frame lock can be provided as part of the frame lock or as an accessory to the frame lock. Through this safety element, the frame lock (and thus the two-wheeled vehicle) can then be connected to a fixed object, such as a street lamp or a two-wheeled vehicle rack. To secure the safety element to the frame lock, the safety element can have a bolt, especially at one end of its long rope shape, and a bolt receiver can be formed at the lock body of the frame lock, in which the bolt can be received and locked.

[0005] Therefore, two blocking mechanisms can be combined in a single frame lock, where ease of operation is advantageous if the two blocking mechanisms can be actuated in a coordinated manner. Operation can thus be improved, in particular, by the fact that the rotating lock ring and the bolt can be unlocked together, preferably by the same locking device. Not only is one of the two blocking mechanisms typically released, for example, before the two-wheeled vehicle moves, but both are released. Operating the frame lock may be easier when locking the two-wheeled vehicle, for example, by first inserting the bolt into the bolt receiver and then adjusting only the rotating lock ring to its locked position. However, the subsequent locking of the rotating lock ring and the bolt can again occur simultaneously.

[0006] The possibility of inserting the bolt into the bolt receiver even when the rotary lock ring has been adjusted to its closed position and locked in that position further contributes to the comfortable use of the frame lock, wherein the bolt is subsequently, preferably, automatically locked in the bolt receiver like an insert. Furthermore, it may be advantageous that if the rotary lock ring is in the open position, it is also possible to insert the bolt into the bolt receiver and then retain the bolt in the receiver so that it does not fall out. In this way, the user can subsequently adjust the rotary lock ring to its closed position and then lock the rotary lock ring and bolt together without having to pay further attention to the bolt in this regard.

[0007] The coordinated operation of these two blocking mechanisms may require additional space due to the connection between the blocking mechanism and additional components (in some cases). However, it is generally considered desirable to keep the frame lock as compact as possible. Furthermore, improvements in operation resulting from the coordinated operation of the blocking mechanisms can be made without compromising the security of the frame lock. Summary of the Invention

[0008] One object of the present invention is to provide a frame lock for two-wheeled vehicles that is simple and flexible to use, has the most compact design possible, and provides a high level of security.

[0009] This objective is achieved by a frame lock having the features described in claim 1. Advantageous further extensions of the invention are derived from the dependent claims, the description, and the drawings.

[0010] A frame lock according to the invention for a two-wheeled vehicle comprises: a lock body extending longitudinally from a first end to a second end and having a rotating lock ring receiver, the lock body having a lock cylinder receiver at the first end and a lock tongue receiver at the second end; a rotating lock ring at least partially housed in the rotating lock ring receiver and adjustable between an open position and a closed position, wherein in the open position the rotating lock ring releases the wheels of the two-wheeled vehicle to rotate, and in the closed position the rotating lock ring prevents the wheels from rotating; a main latch adjustable laterally and linearly in the longitudinal direction between a locked position and an unlocked position, wherein in the locked position the main latch engages with the rotating lock ring receiver by means of a joint to block the rotating lock ring at least in its closed position, and in the unlocked position the main latch releases the rotating lock ring for adjustment; and a locking device housed in the lock cylinder receiver. The device includes a clamp, through which the locking device is connected to the main latch so that the main latch can be adjusted to its unlocked position by the locking device via the clamp; a latch bolt, which is linearly adjustable laterally to longitudinally between a locked position and an unlocked position, wherein in the locked position, the latch bolt engages with a latch receiver by means of a joint to block the latch received therein, and in the unlocked position, the latch bolt releases the latch to disengage it from the latch receiver; and a spring preloads the latch bolt in the direction of the locked position, wherein the connecting portions of the main latch and the latch bolt are connected to each other, particularly directly connected, such that, on the one hand, the latch bolt can be adjusted to its unlocked position by the locking device via the main latch, and on the other hand, the main latch is preloaded by the spring in the direction of its locked position via the latch bolt.

[0011] According to the present invention, the lock body of the frame lock extends longitudinally from its first end to its second end, wherein the lock body has a lock cylinder receiver at the first end and a lock tongue receiver at the second end. Therefore, the first end and the second end are oriented relative to each other with respect to the longitudinal direction.

[0012] At least a central portion of the lock body (e.g., a generally parallelepiped-shaped portion) may extend specifically from the first end to the second end. At both ends, the lock body or the aforementioned central portion may, for example, have corresponding end faces, wherein the two end faces may be specifically oriented to be at least substantially parallel to each other and perpendicular to the longitudinal direction.

[0013] The extension of the lock body does not preclude the lock body from extending beyond the first end and / or the second end, particularly extending obliquely in the longitudinal direction. For example, the lock body may have two arcuate branches that extend obliquely in the longitudinal direction from the corresponding corners of the parallelepiped shape of the central portion of the lock body at the first or second end.

[0014] The cylinder receiver and bolt receiver conveniently extend from the outside into the lock body; that is, they are accessible from the outside—at least if there is no locking device or bolt housed therein. In this respect, they preferably have routes parallel to the longitudinal direction and extend toward each other. The cylinder receiver may extend into the lock body from the end face at a first end of the lock body, and the bolt receiver may extend into the lock body from the end face at a second end of the lock body.

[0015] The lock cylinder receiver and the bolt receiver may each have at least substantially a cylindrical shape and / or a circular cross-section. In this respect, the axis of symmetry of the lock cylinder receiver and / or the axis of symmetry of the bolt receiver (which may (each) correspond to the cylindrical axis of the cylindrical shape) are preferably aligned parallel to the longitudinal direction. The lock cylinder receiver and the bolt receiver may be arranged coaxially with respect to their respective axes of symmetry, which is not absolutely necessary.

[0016] Regardless of its name, a lock cylinder receiver can be specifically used to house a lock cylinder, but is not limited to it; another locking device can also be housed in said lock cylinder receiver. This naming is more suitable for conceptually distinguishing it from a bolt receiver. A bolt receiver can be specifically used to house a bolt, wherein the bolt is conveniently formed at the free end of a fixing element (especially a long rope-like element), which can be used with or provided as part of a frame lock. The fixing element can in particular be a safety chain or safety rope.

[0017] The lock body also has a rotary lock ring receiver. The rotary lock ring is at least partially housed in the rotary lock ring receiver and is adjustable between its open position and its closed position. In the open position, the rotary lock ring releases the wheels of the two-wheeled vehicle to rotate, and in the closed position, the rotary lock ring prevents the wheels from rotating.

[0018] In its closed position, when the frame lock is properly installed on the two-wheeler, the rotary lock ring naturally only prevents the corresponding two-wheeler's wheel from rotating. In other words, the frame lock is configured to be positioned on the two-wheeler such that the rotary lock ring, in its closed position, prevents the two-wheeler's wheel from rotating (especially by engaging through the wheel), and in its open position, releases the wheel to allow it to rotate.

[0019] The rotating locking ring can extend specifically along a circular path, and thus can be adjusted along this circular path between its open and closed positions. Therefore, the adjustment of the rotating locking ring along the circular path corresponds to rotation about an axis of rotation that extends through the center of the circular path, perpendicular to the plane of the circular path (i.e., perpendicular to the plane in which the circular path is disposed). The plane of the circular path is preferably parallel to the longitudinal direction. The axis of symmetry of the lock cylinder receiver, the axis of symmetry of the latch receiver, and / or the axis in which the lock cylinder receiver and the latch receiver are coaxial with each other can be specifically disposed in this plane.

[0020] Depending on the rotational position, the rotating ring can be received along a circular path in the rotating ring receiver of the lock body using a corresponding portion of its extension. In its open position, the rotating ring can, for example, be at least almost completely accommodated in the rotating ring receiver, while in its closed position, the rotating ring protrudes from the rotating ring receiver with a blocking portion and engages with the wheel between the spokes of the respective wheels of a two-wheeled vehicle to block the wheel. This adjustability between the open and closed positions can be attributed in particular to the support of the rotating ring in the rotating ring receiver.

[0021] The main latch is linearly adjustable laterally in the longitudinal direction between a locked position and an unlocked position. In the locked position, the main latch engages with the rotating lock ring receiver via its engagement portion to block the rotating lock ring at least in its closed position. In the unlocked position, the main latch releases the rotating lock ring for adjustment.

[0022] The main latch is preferably disposed entirely within the lock body so that it cannot be accessed from the outside. The main latch can engage with the rotary lock ring receiver because it protrudes from the outside (i.e., from the outside of the rotary lock ring receiver, but within the lock body) into the rotary lock ring receiver. Therefore, the main latch can specifically engage behind the blocking structure of the rotary lock ring housed in the rotary lock ring receiver, thereby blocking the rotary lock ring from adjustment. Conversely, in its unlocked position, the main latch does not engage with the rotary lock ring receiver, or at least does not block the rotary lock ring in that position.

[0023] The rotary lock ring can be specifically configured such that the main latch, adjusted to its locked position and thus engaged in the rotary lock ring receiver, can cooperate with the blocking structure of the rotary lock ring at least in the closed position, thereby preventing the rotary lock ring from deviating from that position. The rotary lock ring is preferably further configured such that the main latch can also cooperate with the blocking structure of the rotary lock ring in the open position, thereby preventing the rotary lock ring from deviating from that position. In this way, the rotary lock ring can not only be locked in its closed position to prevent the frame lock from opening, but can also be secured in its open position by the main latch to prevent accidental closing of the frame lock, especially during travel.

[0024] The linear adjustment of this substance specifically means that the adjustment corresponds to a displacement along a defined straight line direction, that is, a linear distance displacement along that direction or in the opposite direction. In particular, linear adjustment can be a parallel displacement. Linear adjustment preferably corresponds to a pure translation.

[0025] The linear adjustable direction of the main latch is transverse to the longitudinal direction. Here and also hereinafter, "transverse" means that the two corresponding elements arranged laterally to each other are oriented at an angle to each other, the total angle being at least 45°, preferably at least 60°, and especially at least substantially 90°. Therefore, the main latch can be adjusted linearly perpendicular to the longitudinal direction, particularly between its locked and unlocked positions. In this respect, the linear adjustable direction can be oriented at least substantially radially, for example, relative to the center of the rotating locking ring along its extended circular path.

[0026] The locking device is housed in the lock cylinder receiver and has a clamp. The locking device is connected to the main bolt via the clamp, so that the main bolt can be adjusted to its unlocked position by the locking device via the clamp.

[0027] The locking device can be, in particular, a lock cylinder. The locking device is preferably actuated only by a combination, for example, in the form of a key. Actuation of the locking device can, in particular, include adjusting the locking device between a normal position and a released position. In the case of a locking device configured as a lock cylinder, these positions can, for example, correspond to the rotational positions of the lock cylinder body. The key inserted into the cylinder body can then be used in the corresponding rotational position.

[0028] The clamp is preferably disposed entirely within the lock body so that it cannot be accessed from the outside. In this respect, the clamp can be configured as a separate component from the locking device. However, typically, the clamp can also be integrated into the locking device and / or can be formed as a part of the locking device.

[0029] When actuating the locking device, the clamp is preferably always adjusted as well. For example, the clamp can be attached to the core of the locking device configured as a lock cylinder so as to similarly complete each rotation of the core and always have the same rotational position as the core.

[0030] Because of the connection between the main latch and the locking device via the clamp, the main latch can be adjusted to its unlocked position by actuating the locking device. Therefore, a drive transmission occurs from the locking device to the main latch via the clamp in the direction of its unlocked position. Because of the connection between the main latch and the locking device via the clamp, the adjustment of the locking device from its normal position to its released position can, in particular, be guided to cause the main latch to adjust from its locked position to its released position.

[0031] Preferably, the locking device and the main latch are also connected by a clamp, so that the main latch can also be adjusted to its locked position by the locking device via the clamp. However, this connection is not absolutely necessary, at least not when the main latch is pre-tightened to its locked position.

[0032] Furthermore, it is preferable to connect the locking device to the main latch via a clamp, such that there is a clear relationship between the corresponding state or position of the locking device (especially the corresponding rotational position of the lock cylinder if the locking device is configured as a lock cylinder) and the corresponding position of the main latch. Thus, if the main latch is not adjusted simultaneously, the locking device does not need to be adjusted, and vice versa.

[0033] The locking device and the main latch are preferably directly connected via a clamp, i.e., such that no other elements of the frame lock are involved in this drive-effective coupling. The clamp may be, in particular, part of the locking device or acted upon directly by the locking device, and may in turn act directly on the main latch. In this respect, the main latch is preferably formed as a single component. If the clamp is formed separately from the locking device, the clamp may also be, in particular, formed as a single component.

[0034] Furthermore, apart from the connection that links the locking device to the main latch via a clamp, preferably no other effective transmission connection is provided between the locking device and the main latch.

[0035] The latch can be adjusted laterally and linearly between a locked position and an unlocked position. In the locked position, the latch engages with the latch receiver to block the latch contained therein. In the unlocked position, the latch releases the latch to disengage from the latch receiver.

[0036] The latch is preferably fully disposed within the lock body so that it cannot be approached from the outside. Furthermore, the latch is preferably formed as a single component. The latch can engage with the latch receiver using its engagement portion, because the engagement portion protrudes from the outside (i.e., from the outside of the latch receiver, but within the lock body) into the latch receiver. Therefore, the engagement portion can particularly engage behind a blocking structure of the latch received in the latch receiver, which can, for example, include an annular groove formed at the latch to prevent the latch from deviating from the latch receiver. Conversely, in its unlocked position, the latch latch does not engage with the latch receiver using its engagement portion, or at least currently does not prevent the latch from leaving the latch receiver.

[0037] The linear adjustable direction of the latch bolt is preferably perpendicular to the longitudinal direction, and may, for example, be oriented at least substantially radially relative to the center of the circular path along which the rotating lock ring extends. In particular, it is preferred that the linear adjustable direction of the latch bolt is parallel to the linear adjustable direction of the main latch.

[0038] Similar to the main bolt, the latch bolt also has a locked position and an unlocked position. The two locked positions of the latch bolt and the main bolt, and the two unlocked positions of the latch bolt and the main bolt, do not necessarily correspond to each other in terms of their positions, the degree of engagement with the corresponding receivers, and / or another standard. The main bolt and the latch bolt do not necessarily both be in their respective locked positions or their respective unlocked positions in each case. Furthermore, adjustment of the main bolt in at least one direction is possible even if the latch bolt is not also adjusted in this respect; conversely, adjustment of the latch bolt in at least one direction is possible even if the main bolt is not also adjusted in this respect.

[0039] The spring preloads the latch in the direction of its locked position (i.e., in the direction in which the latch bolt moves from its unlocked position to its locked position during adjustment). Specifically, at least in its unlocked position, the latch bolt can be preloaded by the spring in this direction, i.e., act in this direction. Preload is preferably also present in each intermediate position between the unlocked and locked positions, such that the latch bolt is adjusted by the spring to and into its locked position, unless it is temporarily prevented from doing so by another element (e.g., the master latch).

[0040] The spring can be, in particular, a helical spring, preferably a helical tension spring. Preferably, the latch bolt is directly acted upon by the spring. Thus, preload is transmitted from the spring to the latch bolt through direct contact between the spring and the latch bolt. Besides the aforementioned direct action of the spring on the latch bolt, preferably, no other effective transmission connection is provided between the spring and the main latch. Furthermore, no other preload (e.g., via another spring) acts on the latch bolt preloaded in its locked position.

[0041] According to the present invention, the connecting portion of the main latch and the connecting portion of the latch bolt are connected to each other, especially directly connected, such that: on the one hand, the latch bolt can be adjusted to its unlocked position by the locking device via the main latch; on the other hand, the main latch is pre-tightened by a spring in the direction of its locked position via the latch bolt.

[0042] In other words, due to the aforementioned connection between the main bolt and the latch bolt, on the one hand, the locking device and the latch bolt are also indirectly connected to each other (i.e., via the main bolt), and on the other hand, the spring and the main bolt are also indirectly connected to each other (i.e., via the latch bolt). In this respect, the locking device and the latch bolt are only indirectly connected to each other (i.e., only through the main bolt), such that the force flow between the locking device and the latch bolt must be transmitted through the main bolt; and / or the spring and the main bolt are only indirectly connected to each other (i.e., only through the latch bolt), such that the force flow between the spring and the main bolt must be transmitted through the latch bolt. Therefore, apart from the connection via the main bolt, there is no effective transmission connection between the locking device or clamp and the latch bolt that guides through the main bolt; and / or, apart from the connection via the latch bolt, there is no effective transmission connection between the spring and the main bolt that guides through the latch bolt.

[0043] In this article, "connection" should be understood as a transmission connection between two interconnected elements, such that when one of the two elements is adjusted in at least one direction, its movement is directly or indirectly transmitted to the other element, thereby causing the other element to also be adjusted in the corresponding direction.

[0044] The main bolt and the latch bolt can be connected to each other in the manner described above, wherein the connecting portions of the main bolt and the latch bolt interact with each other. Specifically, it can be configured such that when the latch bolt is in its locked position and the main bolt is adjusted (by the locking device) from its locked position to its unlocked position, the connecting portion of the main bolt acts on the connecting portion of the latch bolt; conversely, when the main bolt is in its unlocked position and the latch bolt is adjusted (by the spring) from its unlocked position to its locked position, the connecting portion of the latch bolt acts on the connecting portion of the main bolt.

[0045] When the bolt is received in the bolt receiver, the bolt latch can preferably be adjusted to its unlocked position solely by means of the locking device (i.e., by means of the main bolt), and in fact, especially the main bolt is adjusted to its unlocked position by means of the locking device. Conversely, preferably, the bolt latch can be adjusted to its locked position by preload of a spring. The main bolt can preferably be adjusted to its locked position by means of the locking device, and can be adjusted by preload of a spring—i.e., by means of the bolt latch—at least in the direction of its locked position, especially at least reaching and being in the partially locked position, and possibly also entering the locked position beyond the partially locked position. Conversely, the main bolt can preferably be adjusted to its unlocked position solely by means of the locking device.

[0046] Typically, a frame lock may include multiple springs for pre-tensioning the latch bolt or the main bolt. However, the latch bolt and the main bolt are preferably pre-tensioned only by the springs in the direction of their respective locked positions, i.e., directly pre-tensioning the latch bolt and indirectly pre-tensioning the main bolt via the latch bolt. If multiple springs are provided for pre-tensioning, each of these springs preferably pre-tensions the latch bolt directly (i.e., by direct action) and preferably pre-tensions the main bolt only indirectly (i.e., via the latch bolt).

[0047] The aforementioned connection type (which effectively and pulsatively connects the locking device, its clamp, the main latch, the bolt latch, and the spring to each other) allows the two blocking mechanisms of the frame lock to cooperate comfortably and harmoniously, simplifying the operation of the frame lock. This is achieved by locking the blocking mechanism of the rotating lock ring on one hand and the bolt of the additional fixing element on the other. In this respect, the effective pulsative connection extends entirely along the drive chain formed by the aforementioned elements of the frame lock (from the locking device via the clamp, the main latch, and the bolt latch to the spring, or vice versa), without branches. Therefore, a particularly compact arrangement of these elements along the longitudinal length of the lock body and thus a particularly compact design of the entire frame lock can be achieved.

[0048] According to an advantageous embodiment, the latch has a U-shaped cross-section relative to its linearly adjustable direction (i.e., the direction in which the latch is linearly adjustable between its locked and unlocked positions).

[0049] This U-shape can be formed specifically by a central portion and two other portions, the central portion corresponding to the base of the U-shape, the two portions being adjacent to the central portion on opposite sides and corresponding to the respective branches of the U-shape. In this respect, the central portion can be specifically oriented at least substantially perpendicular to the two other portions. The transition between the portions can be rounded. Furthermore, the central portion can be shorter than the two other portions, where the two other portions do not necessarily have to have the same length.

[0050] Typically, the U-shape may also include at least one further section adjacent to the end of one of the two branches of the U-shape and opposite the central portion, but said at least one further section preferably has a shorter length than the corresponding branch. In this respect, preferably, the U-shape includes at most one such further section. However, typically, the latch may also have more such further sections.

[0051] The two branches of the U-shape are preferably oriented to extend transversely to the longitudinal direction, and more particularly perpendicular to the longitudinal direction. The base of the U-shape is preferably oriented to extend parallel to the longitudinal direction.

[0052] According to another advantageous embodiment, the connecting portion of the latch is formed on a first side surface of the latch, and the engaging portion of the latch is formed on a second side surface of the latch, wherein the latch has a third side surface that connects the first and second side surfaces and contacts the inner wall surface of the lock body.

[0053] The three side surfaces of the latch bolt preferably have a length exceeding the material thickness of the latch bolt (which may specifically correspond to the thickness of the metal sheet forming the latch bolt), and indeed especially in all directions parallel to the respective side surfaces. Thus, the side surfaces are particularly different from the edge surfaces at the end faces of the latch bolt, wherein the length of the edge surfaces in directions parallel to the respective edge surfaces precisely corresponds to the material thickness of the latch bolt and is therefore much smaller than the length of the side surfaces. Along the linearly adjustable direction of the latch bolt, each of the three side surfaces of the latch bolt preferably extends beyond the distance the latch bolt can be adjusted between its unlocked and locked positions, especially more than twice that length, and / or especially at each such position of the latch bolt that spans the position of the axis of symmetry of the latch bolt receiver relative to that direction.

[0054] Each of the first, second, and third side surfaces can be aligned, in particular, parallel to the linearly adjustable direction of the latch bolt. In this respect, the first and second side surfaces are preferably oriented perpendicular to the longitudinal direction and thus aligned parallel to each other. Conversely, the third side surface is preferably aligned parallel to the longitudinal direction and thus can be oriented, in particular, perpendicular to the other two side surfaces. If the latch bolt has the U-shape, the first side surface may correspond to one branch of the U-shape, the second side surface to another branch, and the third side surface to the base of the U-shape. Latch bolts including such side surfaces can be manufactured relatively easily, especially by stamping and bending sheet metal. In particular, the connecting and engaging portions of the latch bolt can also be formed by punching.

[0055] The inner wall may specifically correspond to the inner side of the wall of the lock body. In this respect, the wall may be part of the outer shell of the lock body, wherein the outer side of the wall may be the outer side of the lock body. However, this is not necessarily the case. The wall is preferably formed by an additional metal protective plate of the lock body, disposed within the outer shell of the lock body.

[0056] Because the third side surface contacts the inner wall surface of the lock body, it can also slide along and contact the inner wall when adjusting the bolt. This makes the guidance of the bolt within the lock body particularly stable.

[0057] According to another advantageous embodiment, the main latch has an L-shaped cross-section relative to its linearly adjustable direction (i.e., relative to the direction in which the main latch is linearly adjustable between its locked position and its unlocked position).

[0058] This L-shape can be formed specifically by a first part and a second part, the first part corresponding to the first branch of the L-shape, and the second part adjacent to and oriented perpendicular to the first part and corresponding to the second branch of the L-shape. The transition between the parts can be rounded. Furthermore, the second part can be shorter than the first part.

[0059] Typically, the L-shape may also include at least one distal portion that is adjacent to one of the two portions of the L-shape but preferably has a shorter length than that portion. In this respect, it is preferred that the L-shape includes at most one such distal portion. However, in general, the master latch may also have more such distal portions.

[0060] One of the two branches of the L-shape (especially the first branch) is preferably oriented to extend laterally to the longitudinal direction, and more particularly perpendicular to the longitudinal direction. The other of the two branches of the U-shape (especially the second branch) is preferably oriented to extend parallel to the longitudinal direction.

[0061] According to another advantageous embodiment, the connecting portion of the main latch and the engaging portion of the main latch are formed on a first side surface of the main latch, wherein the main latch has a second side surface that abuts the first side surface and contacts the inner wall surface of the lock body.

[0062] The two side surfaces of the main latch preferably have a length exceeding the material thickness of the main latch (which may specifically correspond to the thickness of the metal sheet forming the main latch), and indeed especially in all directions parallel to the respective side surfaces. Thus, the side surfaces are particularly different from the edge surfaces at the end faces of the main latch, wherein the length of the edge surfaces in directions parallel to the respective edge surfaces precisely corresponds to the material thickness of the main latch and is therefore much smaller than the length of the side surfaces. Along the linearly adjustable direction of the main latch, each of the two side surfaces of the main latch preferably extends beyond the length of the adjustable distance between its unlocked and locked positions, especially more than twice that length, and / or especially at each such position of the main latch that spans the position of the axis of symmetry of the lock cylinder receiver relative to that direction.

[0063] Each of the first and second side surfaces can be aligned, in particular, parallel to the linearly adjustable direction of the main latch. In this respect, the first side surface is preferably oriented perpendicular to the longitudinal direction. Conversely, the second side surface is preferably aligned parallel to the longitudinal direction and can therefore be oriented, in particular, perpendicular to the first side surface. If the main latch has the L-shape, the first side surface may correspond to the first branch of the L-shape, and the second side surface may correspond to the second branch of the L-shape. A main latch including such side surfaces can be manufactured relatively easily, in particular, by stamping and bending metal sheets. The connecting and engaging portions of the main latch can also be formed, in particular, by punching.

[0064] The inner wall of the main latch, which contacts the inner wall of the lock body via its second side surface, can correspond to the inner wall of the lock body, particularly in a manner consistent with the inner wall of the bolt latch, which contacts the inner wall via its third side surface. This inner wall can be formed by a sheet-like metal protective plate disposed within the lock body. In both cases, it can be the same inner wall.

[0065] Because the second side surface contacts the inner wall surface of the lock body, it can also slide along and contact the inner wall when adjusting the main latch. This makes the guidance of the main latch within the lock body particularly stable.

[0066] According to an advantageous embodiment, the linearly adjustable directions of the main bolt and the bolt latch are parallel to each other. This allows for a relatively simple and efficient transmission connection through direct interaction between the main bolt and the bolt latch at their connection points.

[0067] According to another advantageous embodiment, the spring is arranged in a lateral direction adjacent to the latch bolt and / or the main bolt, this lateral direction being perpendicular on one hand to the longitudinal direction and on the other hand to the linearly adjustable direction of the latch bolt and / or the main bolt. This arrangement of the spring adjacent to the latch bolt and / or the main bolt in the lateral direction contributes to the compact design of the frame lock.

[0068] Specifically, the spring can be arranged on the side of the lock body facing the lateral direction, and / or can extend along that side. For example, with respect to the lateral direction, the spring can be arranged (especially captured) between one side of the latch bolt and / or main bolt and the other side of an inner wall of the lock body perpendicular to the lateral direction. This inner wall can particularly correspond to the inner side of a wall of the lock body, which can be part of the lock body housing. Furthermore, the inner wall can particularly be positioned opposite to the inner wall in which the third side surface of the latch bolt and / or the second side surface of the main bolt contacts. Along the side of the lock body facing the lateral direction, the spring preferably extends with respect to the linearly adjustable direction of the latch bolt across the axis of symmetry of the lock cylinder receiver and / or the latch receiver. In this respect, the spring is conveniently aligned at least substantially parallel to this direction. However, in general, the spring can also be oriented at least slightly obliquely.

[0069] According to another advantageous embodiment, the spring, particularly with respect to its direction of action on the latch bolt, is at least substantially aligned parallel to the linearly adjustable direction of the latch bolt. In some cases, especially for installation space reasons, the orientation of the spring may need to deviate from a direction precisely parallel to the linearly adjustable direction of the latch bolt. However, the orientation of the spring is preferably deviated from precise parallel alignment by at most 10°, and especially at most 5°. In this way, the latch bolt can be subjected to maximum force in its locked position. Furthermore, this orientation of the spring also contributes to the compact design of the frame lock.

[0070] Regardless of the arrangement and orientation of the spring, in each case, the spring also preferably acts on the connecting portion of the latch bolt. The connecting portion of the latch bolt then serves not only as an effective drive connection from the latch bolt to the main bolt, but also as an effective drive connection from the latch bolt to the spring, i.e., as an engagement point for pre-tensioning the latch bolt by the spring. The spring may act specifically on one side of the connecting portion of the latch bolt, where said side of the connecting portion is opposite to the other side of the connecting portion, where the connecting portion can be acted upon by the connecting portion of the main bolt. The action of the spring on the connecting portion of the latch bolt is preferably direct. In other words, advantageously, no additional component is provided between the spring and the latch bolt, through which the force applied by the spring is transmitted to the latch bolt, and which would require additional installation space.

[0071] According to another advantageous embodiment, the connecting portion of the latch bolt is formed by a protrusion formed at the latch bolt, which preferably protrudes transversely to the longitudinal direction and transversely to the linearly adjustable direction of the latch bolt (the rest of the latch bolt). In this respect, the connecting portion specifically protrudes relative to one or more portions of the adjacent connecting portion of the latch bolt in the aforementioned manner. In this respect, the connecting portion need not only extend transversely to the longitudinal direction and transversely to the linearly adjustable direction of the latch bolt, but may also extend at least partially parallel to the longitudinal direction, especially to extend to the connecting portion of the main bolt adjacent in the longitudinal direction. For this purpose, the connecting portion of the latch bolt may, for example, be bent accordingly.

[0072] According to another advantageous embodiment, the connecting portion of the main latch is formed by a protrusion formed at the main latch, which preferably protrudes from the main latch (the remainder) transverse to the longitudinal direction and transverse to the linearly adjustable direction of the main latch. In this respect, the connecting portion specifically protrudes relative to one or more portions of the main latch adjacent to the connecting portion in the aforementioned manner. In this respect, the connecting portion need not only extend transverse to the longitudinal direction and transverse to the linearly adjustable direction of the main latch, but may also extend at least partially parallel to the longitudinal direction, especially to extend to the connecting portion of the main latch adjacent in the longitudinal direction. For this purpose, the connecting portion of the main latch may, for example, be bent accordingly.

[0073] According to another advantageous embodiment, when the main latch and the bolt latch are in their respective unlocked positions, the connecting portions of the main latch and the bolt latch are in contact with each other. In this respect, the connecting portions interact with each other in particular.

[0074] Specifically, this state can be achieved by adjusting the main latch to its unlocked position via the locking device, and in this respect, adjusting the bolt latch to its unlocked position via the cooperation of the two connecting parts. In this respect, the bolt latch is adjusted against the preload of a spring, which acts on the bolt latch in the direction of its locked position and also indirectly preloads the main latch in the direction of its locked position via the cooperation of the two connecting parts. The bolt latch can remain in its unlocked position in its unlocked position against this preload by the main latch.

[0075] According to another advantageous embodiment, when the latch bolt is in its locked position and the main bolt is in a partially locked position between its unlocked and locked positions, the connecting portions of the main bolt and the latch bolt contact each other. In this respect, the connecting portions interact with each other in particular.

[0076] Specifically, this state can be achieved by adjusting the latch bolt to its locked position via a spring, and doing so adjusts the main bolt in the direction of its locked position through the cooperation of the two connecting parts. Typically, the travel (i.e., the adjustment distance between the respective unlocked and locked positions) can be the same for both bolts, such that the main bolt is adjusted to its locked position and the two connecting parts are in continuous contact with each other in this respect. However, in this embodiment, the two bolts have different travels, such that by adjusting the latch bolt to its locked position, only the main bolt is adjusted to reach and be in the partially locked position. In this respect, the main bolt is pre-tensioned to this partially locked position by the spring via the latch bolt.

[0077] In this regard, in particular, the partial locking position can be positioned approximately centered between the locked and unlocked positions of the main latch. For example, the length of the adjustment distance between the unlocked and partial locking positions can be equal to at least 30%, preferably at least 40%, and / or at most 70%, preferably at most 60%, of the length of the adjustment distance between the unlocked and locked positions of the main latch.

[0078] In the partially locked position, the master latch is preferably partially engaged with the rotary lock ring receiver by means of its engagement portion, especially up to this point, so that the rotary lock ring is thus prevented from deviating from the open position in the direction of the closed position. Due to the incomplete engagement of the engagement portion, the master latch cannot in this respect engage with the blocking structure of the rotary lock ring in a blocking manner and make it as reliable as if it were in its locked position. However, at least in the open position of the rotary lock ring, this is sufficient to prevent the rotary lock ring from accidentally closing. Conversely, in the closed position of the rotary lock ring, the blocking must also undergo an attempt to disengage, so that the master latch is preferably not only adjusted to the partially locked position but also beyond that partially locked position to reach the locked position—albeit not by preload of a spring.

[0079] In the open position of the rotary lock ring, the linear adjustability of the main latch can be specifically limited between the unlocked and partially locked positions of the rotary lock ring by a corresponding design of the rotary lock ring or a cover or band located at the rotary lock ring. This ensures that when the rotary lock ring is in the open position, the main latch cannot be adjusted to reach and be in the locked position at all. Since the main latch is connected to the locking device via a clamp, it prevents the locking device from being adjusted to its normal position corresponding to the locked position of the main latch. If the key can only be removed from the locking device in this normal position, it can be prevented from being removed in the open position of the rotary lock ring in this way. This corresponds to the so-called key retention function, especially the key retention function required in some European countries.

[0080] In this embodiment, when the latch bolt is in its locked position and the main bolt is in its partially locked position, the connecting parts contact each other, thereby allowing this key retention function, but not necessarily limiting the frame lock to this function. Instead, this embodiment allows the key retention function to be selectively implemented or omitted by using a rotary lock ring of appropriate construction (or a rotary lock ring with a correspondingly formed cover or band).

[0120] L longitudinal direction Detailed Implementation

[0121] The accompanying drawings illustrate an embodiment of a frame lock 11 according to the invention. The frame lock 11 includes a lock body 13 having a housing 15 that is at least substantially C-shaped, wherein the central portion of the C-shape is widened into a parallelepiped shape, and two remaining portions form a first branch 17 and a second branch 19 of the lock body 13, wherein the first branch 17 and the second branch 19 extend from the corners of the parallelepiped shape. Utilizing the central portion, the lock body 13 extends along a longitudinal direction L from a first end 21 to a second end 23, wherein the lock body 13 has corresponding end faces oriented perpendicular to the longitudinal direction L at both ends 21 and 23.

[0122] like Figure 2The cross-sectional view specifically shows that a cylinder receiver 25 extends from the end face of the first end 21 parallel to the longitudinal direction L into the lock body 13, wherein a locking device 27 in the form of a cylinder is housed within the cylinder receiver 25. The locking device 27 can be actuated only in a conventional manner, i.e., adjusted between different rotational positions of the cylinder core of the locking device 27 by a key 29 associated with the locking device 27. A bolt receiver 31 extends from the end face of the second end 23 parallel to the longitudinal direction L into the lock body 13, wherein a bolt 33 of a long rope-like fixing element in the form of a safety chain (not shown further) can be housed within the bolt receiver 31. Furthermore, an entrainer 35, a main bolt 37, and a bolt latch 39 are housed within the central portion of the lock body 13.

[0123] The frame lock 11 also has a rotating locking ring 41 that extends along a circular path and is at least partially received in the housing 15, i.e., received in the rotating locking ring receiver 43 (see...). Figure 2 The rotating lock ring receiver 43 extends through the first branch 17, enters the central portion of the parallelepiped shape of the lock body 13, and reaches and enters the second branch 19. In this respect, the rotating lock ring 41 is supported relative to the lock body 13, allowing it to... Figure 1 and Figure 3 The closed position shown is the same as Figure 7 The open positions shown are adjustable along their longitudinal range (i.e., along the circular path), meaning they can rotate about a rotation axis extending through the center of the circular path in a plane perpendicular to it. The rotating locking ring 41 is made of metal and has a constant circular cross-section, but it can also typically have another shape, such as a regular polygon.

[0124] In the closed position, the rotating locking ring 41 extends from the first branch 17 and reaches the second branch 19, entering the second branch 19, thus connecting the two branches 17 and 19, as well as the lock body 13 and the rotating locking ring 41, thereby forming a closed loop (see...). Figure 1 In this way, for the corresponding arrangement of the frame lock 11 on the frame of the two-wheeled vehicle (not shown), the rotary lock ring 41 can be engaged between the spokes of the two-wheeled vehicle by the wheels of the two-wheeled vehicle, and thus can prevent the wheels from rotating.

[0125] Conversely, in the open position, the swivel lock 41 is at least substantially completely contained within the housing 15, or extends only slightly from the first branch 17 of the housing 15, thus maintaining free space between the two branches 17, 19, in which the spokes of the wheel can move through between the branches 17, 19 of the frame lock 11. Therefore, in its open position, the swivel lock 41 releases the wheels of the two-wheeled vehicle for rotation.

[0126] Main latch 37 can be Figure 2 and Figure 3 The lock position shown is the same as Figure 5 and Figure 6 The unlocking positions shown are linearly adjustable perpendicular to the longitudinal direction L. In the locked position, the main latch 37 engages with the rotary lock ring receiver 43 via a coupling 45. This is particularly feasible when the rotary lock ring 41 is in its closed position. In the locked position of the main latch 37, the coupling 45 of the main latch 37 then engages with the blocking structure of the rotary lock ring 41, such that the coupling 45 blocks the adjustment of the rotary lock ring 41 in the direction of the open position, in particular, such that the coupling 45 engages behind one or more adjacent portions of the blocking structure of the rotary lock ring 41 relative to the path of the circular path. Conversely, in the unlocked position of the main latch 37, the coupling 45 does not engage with the rotary lock ring receiver 43, or at most engages only with the rotary lock ring receiver 43, allowing the rotary lock ring 41 to be adjusted between its closed and open positions.

[0127] Specifically, such as Figure 6 As shown, in the illustrated embodiment, the engagement portion 45 of the main latch 37 has a semi-circular profile, wherein the engagement portion 45, in its locked position, utilizes this semi-circular profile to join approximately half of the circumference of the rotating lock ring 41. In this respect, the engagement portion 45 of the main latch 37 is forked. Therefore, the engagement portion 45 can engage behind the web 65, which protrudes from the plane of the rotating lock ring 41 perpendicular to the circular path on both sides of the rotating lock ring 41 (i.e., on both sides of the plane defined by the circular path along which the rotating lock ring 41 extends) and is part of the blocking structure. In this respect, the abutment is formed by the end face of the web 65, oriented perpendicular to the circular path. Only when the main latch 37 is in its unlocked position, as... Figure 6 As shown, the rotating locking ring 41 can be guided along with the web plate 65 through the main latch 37, and thus can be adjusted from its closed position to its open position.

[0128] The clamp 35 is configured as a separate component from the locking device 27 and is coupled to the core of the locking device 27 for co-rotation (see [link]). Figure 3 , Figure 5 and Figure 7The main latch 37 is also connected to the locking device 27 via a clamp 35, and in effect, it can be adjusted between its unlocked and locked positions by means of the key 29 actuating the locking device 27. In this respect, in particular, there is a clear relationship between the corresponding positions of the main latch 37 and the corresponding rotational positions of the clamp 35, the core of the locking device 27, and the key 23. In this respect, the locked position of the main latch 37 corresponds to the normal position of the locking device 27 or the key 23, and in this respect, the unlocked position of the main latch 37 corresponds to the released position of the locking device 27 or the key 23.

[0129] The locking bolt 39 can be linearly adjustable in a direction perpendicular to the longitudinal direction L and parallel to the main bolt 37. Figure 2 , Figure 3 , Figure 4 and Figure 7 The lock position shown is the same as Figure 5 The unlocked positions are linearly adjusted. In the locked position, the latch 39 engages with the latch receiver 31 via a engagement 47. If the latch 33 of the fixing element associated with the frame lock 11 is received in the latch receiver 31, the engagement 47 of the latch latch 39 can then cooperate in its locked position with a blocking structure (in particular in the form of an annular groove 49) formed on the latch 33, such that it blocks the latch 33 away from the latch receiver 31, in particular that the engagement 47 engages in the annular groove 49 and thus engages behind the adjacent portion that laterally defines the annular groove 49 relative to the longitudinal direction L. Conversely, in the unlocked position of the latch latch 39, the engagement 47 does not engage in the latch receiver 31, or at most engages only in the latch receiver 31 so that the latch 33 can be removed from the latch receiver 31.

[0130] Specifically, such as Figure 4 As shown, in the illustrated embodiment, the engagement portion 47 of the latch 39 has a semi-circular profile, which engages in the annular groove 49 of the latch 33 in its locked position, such that the engagement portion 47 contacts the annular groove 49 (i.e., its base) at approximately more than half, but at least more than one-quarter, and preferably more than one-third, of the perimeter of the annular groove 49. The latch 33 is thus locked particularly reliably by the latch 39.

[0131] Spring 51 in the form of a helical compression spring (which can be Figure 3 , Figure 5 and Figure 7(As seen in the image) is further housed within the lock body 13. The spring 51 is aligned generally parallel to the linearly adjustable direction of the main latch 37 and the bolt latch 39, and is arranged transversely to this direction and transversely to the longitudinal direction L adjacent to the bolt latch 39. Thus, the spring 51 is constrained between the bolt latch 39 and a sidewall of the housing 15 that defines the lock body 13 transversely to the longitudinal direction L and transversely to the linearly adjustable direction of the bolt latch 39. Figure 1 In the middle, the sidewall (its in Figure 3 , Figure 5 and Figure 7 (Not shown in the image) is arranged facing outward relative to the image plane. Spring 51 acts on the latch 39 and thus preloads it in the direction of its locked position. Due to this preload, the latch 39 automatically adjusts to its locked position unless it is pushed into or held in another position by the latch 33 or the main latch 37.

[0132] Each of the main bolt 37 and the latch bolt 39 has a connecting portion 53 or 55, which is formed by a protrusion formed at the main bolt 37 or the latch bolt 39 and protruding from the main bolt 37 or the latch bolt 39 in a linearly adjustable direction transverse to the longitudinal direction L and transverse to the main bolt 37 and the latch bolt 39 (see...). Figures 3 to 7 In particular, it also refers to Figure 4 and Figure 6 Specifically, the connecting portions 53 and 55 protrude in the direction in which the spring 51 is arranged adjacent to the latch 39. Therefore, the spring 51 can act directly on the connecting portion 55 of the latch 39.

[0133] A portion of the connecting portion 55 of the latch bolt 39 (which is distal relative to the rest of the latch bolt 39) bends relative to its proximal portion, such that the connecting portion 55 also protrudes from the rest of the latch bolt 39 parallel to the longitudinal direction L, and in fact protrudes toward the main bolt 37. Therefore, the connecting portion 55 of the latch bolt 39 (i.e., its distal portion) and the connecting portion 53 of the main bolt 37 overlap with respect to the linearly adjustable direction of the main bolt 37 and the latch bolt 39. In this respect, the connecting portion 55 of the latch bolt 39 is offset relative to the connecting portion 53 of the main bolt 37 in the direction in which the main bolt 37 and the latch bolt 39 can be adjusted from their respective locked positions to their respective unlocked positions. As a result, when the main latch 37 is adjusted in the direction of its unlocked position, the connecting part 53 of the main latch 37 acts on the connecting part 55 of the latch bolt 39, and when the latch bolt 39 is adjusted in the direction of its locked position, the connecting part 55 of the latch bolt 39 acts on the connecting part 53 of the main latch 37.

[0134] Due to the cooperation of the connecting portions 53 and 55 of the main latch 37 and the latch bolt 39, the main latch 37 and the latch bolt 39 are connected to each other, such that: on the one hand, the latch bolt 39 can be adjusted to its unlocked position by the locking device 27 via the main latch 37; on the other hand, the main latch 37 is pre-tightened by the spring 51 in the direction of its locked position via the latch bolt 39. That is, entering... Figure 7 The partial locking position is shown, wherein the partial locking position is located between the unlocked position and the locked position of the main latch 37. Due to this connection, the actuation of the key 29 from the normal position to the released position is ultimately transmitted through the core of the locking device 27, the clamp 35, and the main latch 37 to the bolt latch 39, which then moves against the preload of the spring 51 to its unlocked position and releases the bolt 33. In the opposite direction, the spring 51 not only preloads the bolt latch 39 to its locked position, but also preloads the main latch 37 via the bolt latch 39 to enter the partial locking position, and preloads the core of the locking device 27 and the key 29 inserted therein in the direction of the normal position via the main latch 37 and the clamp 35 to enter the rotational position (see [link]). Figure 7 The rotational position is set between the normal position and the release position and corresponds to the partially locked position of the main latch 37.

[0135] Both the main latch 37 and the tongue latch 39 are formed as perforated sheet metal assemblies. In this respect, the main latch 37 is bent along a curved edge, such that it has a substantially L-shaped cross-section, at least relative to its linearly adjustable direction (see...). Figure 6 The longer first branch of the L-shape corresponds to the first side surface 57.1 of the main latch 37, which is oriented perpendicular to the longitudinal direction L, and the shorter second branch of the L-shape corresponds to the second side surface 57.2 of the main latch 37, which is aligned parallel to the longitudinal direction L. Both the engagement portion 45 and the connecting portion 53 of the main latch 37 are formed at the first side surface 57.1 of the main latch 37.

[0136] The latch 39 is curved along its two curved edges, such that it has at least substantially a U-shaped cross-section relative to its linearly adjustable direction (see...). Figure 4 The two branches of the U-shape correspond to the first side surface 59.1 or the second side surface 59.2 of the latch 39, each oriented perpendicular to the longitudinal direction L. The central portion of the U-shape connecting the two branches corresponds to the third side surface 59.3 of the latch 39, aligned parallel to the longitudinal direction L. The connecting portion 55 of the latch 39 is formed at the first side surface 59.1 of the latch 39, while the engaging portion 47 of the latch 39 is formed at the second side surface 59.2 of the latch 39.

[0137] The two side surfaces parallel to the longitudinal direction L, namely the second side surface 57.2 of the main latch 37 and the third side surface 59.3 of the bolt latch 39, contact the inner wall 61 formed by the inner side of the metal protective plate 63 housed in the lock body 13 (see...). Figure 3 , Figure 5 and Figure 7 Due to contact, the main latch 37 and the bolt latch 39 slide along the inner wall 61 during adjustment and are thereby guided. In this way, tilting of the main latch 37 or the bolt latch 39 can be particularly reliably avoided.

[0138] exist Figure 3 In the closed state of the frame lock 11 shown, the rotary lock ring 41 is in its closed position, and both the main bolt 37 and the bolt latch 39 are in their locked positions, thereby preventing the rotary lock ring 41 from adjusting from its closed position and preventing the bolt 33 housed in the bolt receiver 31 from leaving the bolt receiver 31. By using the key 29 from Figure 3 Rotate to the normal position shown Figure 5 The main latch 37 is adjusted to the release position shown by the clamp 35. Figure 5 The unlock position is shown, where, Figure 3 In the normal position shown, key 29 can be inserted into and removed from locking device 27. Figure 5 In the release position shown, key 29 is captured in locking device 27.

[0139] When the main latch 37 is adjusted to its unlocked position, the connecting portion 53 of the main latch 37 strikes the connecting portion 55 of the bolt latch 39, and then acts on it, causing the bolt latch 39 to also be adjusted to the unlocked position. Figure 5 The unlocked position is shown, and in fact, it resists the preload of the spring 51. As a result, the engagement portion 47 of the latch 39 no longer engages with the annular groove 49 of the latch 33, allowing the latch 33 to be removed from the latch receiver 31.

[0140] Since the main latch 37 is adjusted to its unlocked position, the rotating locking ring 41 is no longer prevented from adjusting in its open position by the engagement of the engagement portion 45 of the main latch 37. The rotating locking ring 41 is preferably pre-tensioned to the open position by a spring 67 configured as a helical tension spring, so that the rotating locking ring 41 subsequently automatically adjusts to the open position due to this pre-tension. However, in Figure 5 and Figure 6In the intermediate state of the frame lock 11 shown, the rotating lock ring 41 has not yet reached its open position. During the adjustment of the rotating lock ring 41 between its open and closed positions, the main latch 37, and indirectly via the main latch 37, also keeps the latch bolt 39 in their respective unlocked positions by means of the band 69, which is arranged as a cover at the rotating lock ring 41, and specifically extends between the two webs 65 of the rotating lock ring 41 that project in the same direction (see...). Figure 5 ).

[0141] When the rotary locking ring 41 reaches the open position, the main latch 37 and the bolt latch 39 are no longer held in their respective unlocked positions by the band 69. Therefore, the bolt latch 39 is adjusted to its locked position by the preload of the spring 51, thereby adjusting the main latch 37 in the direction of its locked position due to the connection via the connecting parts 53 and 55. Since the bolt latch 39 cannot be adjusted beyond the locked position, the preload of the spring 51 acts on the main latch 37 via the bolt latch 39 only before the bolt latch 39 reaches its locked position. In this respect, the main latch 37 is only adjusted to its partially locked position, in which the main latch 37 is partially engaged with the rotary locking ring receiver 43 by its engagement part 45 and is engaged behind the web 65 of the rotary locking ring 41, thus fixing the rotary locking ring 41 in its open position. This open state of the frame lock 11... Figure 7 As shown in the image.

[0142] Normally, in this state, the main latch 37 can still be adjusted to reach and be in its locked position, i.e., manually adjusted by turning the key 29 to the normal position. However, in the illustrated embodiment, the strip 69 is configured such that when it is in the open position of the rotating lock ring 41 together with the rotating lock ring 41, it limits the linear adjustability of the main latch 37 to adjustment between the unlocked position and the partially locked position. Therefore, in the open position of the rotating lock ring 41, the main latch 37 may not be able to be adjusted beyond the partially locked position in the direction of the locked position. Therefore, it is particularly impossible to remove the key 29 in this state from the lock. Figure 7 The shown intermediate position is rotated to the normal position. In this way, in terms of the key retention function, it is ensured that the key 29 can only be removed from the locking device 27 when the frame lock 11 is in the closed state.

[0143] To close the frame lock 11, key 29 can be turned to the release position, thereby adjusting the main bolt 37 and the latch bolt 39 to their respective unlocked positions, and rotating the lock ring 41 can then overcome the preload of spring 67 and be adjusted to its closed position. With the lock ring 41 in the closed position, the preload of spring 51 causes the latch bolt 39 to enter its locked position, and via the latch bolt 39, the main bolt 37 is also forced to reach and be in its partially locked position. Furthermore, with the lock ring 41 in the closed position, by turning key 29 to the normal position, the main bolt 37 can be adjusted beyond the partially locked position to reach and be in its locked position, so that the frame lock 11 is then back in its closed state and key 29 can be removed from the frame lock 11.

[0144] Because the preload of spring 51 adjusts the main latch 37 to its partially locked position via the latch 39 when the rotary lock ring 41 reaches the closed position, the rotary lock ring 41 is automatically secured to prevent it from being adjusted back to the open position by spring 67. Since the rotary lock ring 41 can be released after being adjusted to the open position and before the key 29 is subsequently turned to its normal position to adjust the main latch 37 to its locked position and thus fully lock the rotary lock ring 41, this allows the frame lock 11 to be closed with only one hand.

[0145] In this respect, the bolt 33 can be inserted into the bolt receiver 31 in both the open and closed states (and in between) of the frame lock 11. For the bolt latch 39, if it is not in its unlocked position in any way, it can only be held in its locked position by the preload of the spring 51. Therefore, when the bolt latch 39 is in its locked position, it can always (especially independently of the corresponding position of the main bolt 37) overcome the preload of the spring 51 and be adjusted to its unlocked position, and advantageously, in fact, directly by inserting the bolt 33 into the bolt receiver 31.

[0146] In this respect, the arrangement can be specifically made such that (as in the example shown) the diameter of the latch 33 decreases toward the free end in the end portion of the latch 33, particularly in the portion between the annular groove 49 and the free end of the latch 33, thereby forming a continuous chamfer, particularly a tapered continuous chamfer. In this respect, the continuous chamfer is formed such that when the latch 33 is introduced into the latch receiver 31 in the longitudinal direction L, the latch latch 39 is pushed back from its locked position in the direction of its unlocked position by the continuous chamfer transversely to the longitudinal direction L, so that the end portion can be guided through the latch latch 39. Subsequently, the latch latch 39 can be readjusted back to its locked position by the preload of the spring 51 while locked in the latch 33 (particularly locked in its annular groove 49).

[0147] In this way, the latch 33 can always be easily and comfortably inserted into the frame lock 11 and can then be automatically secured in the latch receiver 31—in which case the frame lock 11 closes so as to not only block the respective wheels of the two-wheeled vehicle by rotating the lock ring 41, but also to connect the entire two-wheeled vehicle to a stationary object by means of the fixing element in which the latch 33 is provided; or in which case the frame lock 11 opens so that the latch 33 can be inserted, and then the rotating lock ring 41 can be freely closed and locked by hand.
