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. To this end, 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] The frame lock specifically includes a lock body and a rotating lock ring, wherein the lock body includes a latch, and the rotating lock 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. In the open position, the rotating lock ring releases the wheels of a two-wheeled vehicle for rotation, and in the closed position, it prevents the wheels from rotating. The rotating lock ring has a blocking structure including an adjacent portion, wherein the latch is adjustable between an unlocked position and a locked position, and wherein, when the rotating lock ring is in its closed position and the latch is in its locked position, the latch engages behind the adjacent portion and thereby prevents the rotating lock ring from being adjusted to the open position.

[0004] The stability of the rotary lock ring is a decisive factor affecting the reliability of frame locks. Therefore, frame locks should be designed to be as difficult to open as possible through destructive means, requiring the rotary lock ring to be exceptionally robust. Simultaneously, the rotary lock ring should be manufactured as cost-effectively and automatically as possible.

[0005] The swivel lock ring for a frame lock can be manufactured, for example, from a bar bent into an arc shape, particularly from metal wire. To form the blocking structure including the abutment, a notch can be formed in the bar by chip forming machining, such as punching or milling. In this respect, the sidewall of the notch can form the abutment. However, a disadvantage of chip forming machining is that the machined material is weakened because the fibers running longitudinally through the bar are cut. This can especially cause deformation during the subsequent hardening of the swivel lock ring, which may even lead to a halt in subsequent straightening. Summary of the Invention

[0006] One object of the present invention is to provide a frame lock for a two-wheeled vehicle, the frame lock comprising a rotating locking ring for such a frame lock, which can be easily manufactured, as inexpensive as possible and automated, has a particularly stable structure in this respect, and is suitable for securing a two-wheeled vehicle in a particularly reliable manner.

[0007] The objective is achieved by a frame lock having the features of claim 1. Advantageous embodiments arise from the dependent claims, this specification, and the drawings.

[0008] The frame lock for a two-wheeled vehicle according to the invention includes a lock body and a rotating lock ring, the lock body having a latch, the rotating lock ring extending along a circular path and adjustable relative to the lock body along the circular path 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.

[0009] The swivel ring is preferably formed from a bar, particularly from a metal wire such as steel wire, wherein the bar preferably has a constant cross-section. The diameter of the circular path can, for example, be in the range of 10 cm to 15 cm, and can, for example, reach about 13 cm. In the cross-section, the swivel ring can have a diameter on the order of several millimeters to several centimeters. For example, the diameter of the cross-section can be at least on average about 8 or 9 mm. Due to the length of the circular path, the swivel ring has an arcuate shape that extends overlapping with a specific portion of the circularly closed circular path, for example, extending overlapping with an angular range of at least 200° and / or at most 250°, preferably at least 210° and / or at most 240°, particularly about 225° or 230°.

[0010] Since the rotating locking ring can be adjusted between the open and closed positions, it can be adjusted from the open position to the closed position and enter the closed position in the closing direction; conversely, it can be adjusted from the closed position to the open position and enter the open position in the opening direction, which is opposite to the closing direction. However, it is therefore possible that the rotating locking ring can also be adjusted in another way, particularly by adjusting beyond the closed position in the closing direction and / or by adjusting beyond the open position in the opening direction.

[0011] When adjusting the rotating locking ring along the circular path, the rotating locking ring moves along the circular path, and its longitudinal curvature is such that it does not leave the circular path, but extends only overlapping with a portion of the circular path that changes relative to its position (rather than relative to its angular range). In this respect, the adjustment of the rotating locking ring corresponds to the rotation of the rotating locking ring about a rotation axis that extends through the center of the circular path and is oriented perpendicular to the plane in which the circular path is arranged.

[0012] The adjustability of the rotating locking ring along a circular path is a fundamental adjustability, which can be caused in particular by the corresponding support of the rotating locking ring at the lock body. However, adjustability is not necessarily permanent, but can be blocked by the latch, in particular by which the rotating locking ring can be fixed in one or more different specific positions. Preferably, if the latch or any obstruction in the path of movement (e.g., the spokes of a two-wheeled vehicle's wheel) does not obstruct adjustment, the rotating locking ring can be adjusted at least from the open position to the closed position and into the closed position, and from the closed position to the open position and into the open position.

[0013] The circular path can extend partially through the lock body of the frame lock, allowing the rotating lock ring to extend partially into or through the lock body and, in this respect, cooperate with the latch within the lock body. Preferably, the latch is entirely housed within the lock body's outer casing so that it is as inaccessible as possible from the outside. The rotating lock ring can also be partially housed within the lock body's outer casing. The rotating lock ring can be specifically supported at this casing.

[0014] In the closed position, the rotating locking ring preferably extends out of the lock body, particularly out of the outer casing of the lock body, and then at least its free end returns to the lock body, particularly extending into the outer casing, such that the lock body and the rotating locking ring preferably form a closed loop in the closed position. In this way, rotation of the corresponding wheel can be prevented particularly reliably. Conversely, in the open position, the rotating locking ring extends out of the lock body but does not return to the lock body, or is at least almost completely contained within the lock body, particularly within the outer casing.

[0015] In its closed position, when the frame lock is properly mounted on a two-wheeled vehicle, the rotary lock ring naturally only prevents the wheels of the corresponding two-wheeled vehicle from rotating. In other words, the frame lock is configured to be arranged on the two-wheeled vehicle such that the rotary lock ring prevents the wheels of the two-wheeled vehicle from rotating in its closed position (specifically by engaging through the wheels), and releases the wheels to rotate in its open position.

[0016] According to the present invention, the rotary locking ring has a blocking structure including an adjacent portion, wherein the latch is adjustable between an unlocked position and a locked position, and wherein, when the rotary locking ring is in its closed position and the latch is in its locked position, the latch engages behind the adjacent portion to prevent the rotary locking ring from adjusting into the open position.

[0017] The latch can be adjustable, in particular, relative to the housing of the lock body, between an unlocked position and a locked position. This adjustment can be, for example, a linear shift. Preferably, the latch can be adjusted solely by a locking device, preferably in the form of a lock cylinder, located at (particularly within) the lock body, wherein the latch is coupled to the lock cylinder, for example, via a clamp, and the lock cylinder can be actuated solely by the key associated with it.

[0018] The adjustability of the latch is also a fundamental adjustability, which need not be permanent but can be specifically dependent on the corresponding position of the rotating locking ring. Preferably, at least when the rotating locking ring is in its closed position, the latch can be adjusted from the unlocked position to the locked position and into the locked position; and conversely, from the locked position to the unlocked position and into the unlocked position. Furthermore, in particular, when the rotating locking ring is in its open position, the latch can also be adjusted from the unlocked position to the locked position and into the locked position, and vice versa.

[0019] Therefore, the rotating locking ring can be secured in its closed position by a latch, wherein the latch is adjusted to its locked position and then engages behind the adjacent portion of the blocking structure of the rotating locking ring. If the adjacent portion is oriented at least substantially perpendicular to the direction in which the movement of the rotating locking ring is to be blocked (i.e., towards the path of the circular path), then preventing the adjustment of the rotating locking ring along the circular path is particularly reliable, and is therefore preferred.

[0020] The adjacent portion is preferably (but not necessarily) formed as an adjacent surface, i.e., formed as a face. The adjacent portion can also typically be formed by the edge or contour of the barrier structure.

[0021] The blocking structure can be formed in many different ways. A commonly conceivable approach is that the blocking structure includes a cut or notch in the rotating ring, wherein the cut or notch can extend radially from the outside to the inside of the rotating ring, particularly relative to the center of the circular path. In this respect, the adjacent portion can be formed as a sidewall of such a cut or notch.

[0022] The blocking structure may have multiple adjacent portions, each of which may be latched at the rear to ensure that different positions of the rotating locking ring do not deviate from their respective positions in at least one adjustment direction. In this respect, the multiple adjacent portions can be used to fix the same position in any of the same adjustment direction or mutually opposite adjustment directions.

[0023] The engagement of the latch behind the adjacent portion should be understood as relating to the adjustment of the rotating locking ring to be blocked. In this respect, the latch engages in the movement path of the adjacent portion in particular transverse to the circular path, wherein the adjacent portion will pass through the latch if the latch is in its unlocked position and the rotating locking ring is adjusted along the circular path in the direction of adjustment to be blocked.

[0024] When the swivel ring is in its closed position and the latch is in its locked position, the latch preferably contacts the adjacent portion, or at least has only a small gap from the adjacent portion, for example, less than 1 mm, particularly a few hundred micrometers. Therefore, the swivel ring is advantageously secured and will not deviate from the closed position in the direction of the open position at all. However, typically, the latch can also have a larger gap from the adjacent portion, such that the swivel ring can actually be adjusted from the closed position to a distance corresponding to that gap, but in any case, it is prevented from reaching a position where the swivel ring will no longer reliably prevent the wheel from rotating.

[0025] In the frame lock, the blocking structure is also configured such that it includes at least one web protruding from the rotating lock ring, particularly transverse to the longitudinal extent of the rotating lock ring, and has an adjacent portion.

[0026] In this respect, it is not necessary for the entire web to protrude from the rotating ring; rather, it is sufficient for the web to protrude partially from the rotating ring. A portion of the web may also extend into the rotating ring, particularly extending transversely to the longitudinal extent of the rotating ring. The portion of the web protruding from the rotating ring can, in particular, be a convex structure relative to its surroundings.

[0027] For example, the web may protrude relative to the cross-section of the adjacent portion of the swivel ring, particularly relative to the cross-section of the bar from which the swivel ring is formed before the blocking structure or at least the web has been formed thereon. In this respect, a web protruding in cross-section specifically means that, when viewed along the length of the swivel ring in a circular path, the web extends beyond the outer contour of the cross-section.

[0028] The direction in which the web protrudes is preferably perpendicular to the longitudinal range of the swivel ring. In particular, this direction may be at least substantially radial relative to the center of the cross-section of the swivel ring that is perpendicular to the longitudinal range of the swivel ring.

[0029] The adjacent portion is preferably formed directly on the web. For example, the adjacent portion may be formed from the end face of the web. In this respect, the adjacent portion may also protrude completely or at least partially from the swivel ring.

[0030] Therefore, the web represents part of a blocking structure, in which the latch cooperates to prevent the rotating locking ring from adjusting from its corresponding position. For this purpose, the web is advantageously formed at the corresponding position of the rotating locking ring. In other words, the web is configured such that (in particular, arranged such that) when the rotating locking ring is in its closed position and the latch is in its locked position, the latch engages behind the adjacent portion of the web.

[0031] The web (in particular the entire blocking structure) is preferably arranged in a section of the longitudinal range of the rotating lock ring (i.e., the length of the rotating lock ring along the circular path), wherein this section is arranged in the lock body, in particular in the outer shell of the lock body, whether the rotating lock ring is in the closed position or in the open position (and in any position in between), and is therefore advantageously inaccessible from the outside.

[0032] The object of the invention is achieved not only by the frame lock as a whole, but also by the rotating locking ring for such a frame lock (which is constructed in a manner corresponding to the rotating locking ring of the described frame lock). In this respect, independent of the frame lock described, the invention also relates to a rotating locking ring for a frame lock for a two-wheeled vehicle, the rotating locking ring extending along a circular path and having a blocking structure including an abutment portion, wherein the abutment portion is configured to be engaged rearward by an adjustable latch of the lock body of the frame lock, such that the rotating locking ring is thereby blocked in at least one adjustment direction to prevent adjustment along the circular path, wherein the rotating locking ring is characterized in that the blocking structure includes at least one web plate projecting from the rotating locking ring and having the abutment portion. The foregoing and subsequent explanations regarding the frame lock according to the invention, particularly regarding its rotating locking ring, and the description of different possibilities for the design of the frame lock, also apply to the rotating locking ring of the invention to the extent applicable. Not only embodiments of the frame lock according to the invention, but also advantageous embodiments of the rotating locking ring according to the invention, at least if these embodiments can be applied to the rotating locking ring, are particularly derived from the features of the dependent claims.

[0033] According to a preferred embodiment, the adjacent portion (preferably the entire web) is formed by cold forming. Specifically, the web can be formed by means of a punch moving against a support member, wherein the portion of the rotating ring disposed between them is extruded, such that this portion is compressed parallel to the extrusion direction and stretched laterally. Thus, the portion deformed in this way partially protrudes from the rest of the rotating ring. In this respect, the cold forming can be performed by impact extrusion, particularly transverse impact extrusion, or at least in a similar manner. The entire blocking structure is preferably formed by non-chip forming machining of the rotating ring. The entire rotating ring, except for the end sections at both ends in the longitudinal direction of the rotating ring, can be particularly machined only by non-chip forming.

[0034] For example, a recess can be formed in a rotary lock ring by cold forming. The adjacent portion can then be formed by a sidewall of the recess that defines the recess in the direction along the circular path.

[0035] Compared to chip forming of rotary lock rings, cold forming offers the advantage of causing less damage to the material structure. In particular, cold forming can prevent the breakage of fibers important to the stability of the material structure, especially the main fibers extending along the longitudinal direction of the rotary lock ring.

[0036] This advantage also depends on the formation of the web protruding from the rotating lock ring. Therefore, in particular, the object of the invention can also be achieved by means of cold forming the adjacent portion. In this respect, independent of the aforementioned frame lock, the invention also relates to a frame lock for a two-wheeled vehicle comprising a lock body and a rotating lock ring, the lock body including a latch, the rotating lock ring extending along a circular path and adjustable relative to the lock body along the circular path between an open position and an open position, in which the rotating lock ring releases the wheels of the two-wheeled vehicle for rotation, and in a closed position, the rotating lock ring prevents the wheels from rotating, wherein the rotating lock ring has a blocking structure including an adjacent portion, wherein the latch is adjustable between an unlocked position and a locked position, and wherein, when the rotating lock ring is in its closed position and the latch is in its locked position, the latch engages behind the adjacent portion to prevent the rotating lock ring from adjusting to the open position, wherein the frame lock is characterized in that the adjacent portion is formed by cold forming. Preferably, the entire blocking structure is formed by non-chip forming machining of the rotating lock ring. Except for the end sections at both ends of the longitudinal range of the swivel ring, the entire swivel ring can be specifically machined only in a non-chip forming manner.

[0037] Furthermore, the object of the invention is also achieved by a corresponding rotary locking ring for a frame lock. In this respect, independent of the aforementioned frame lock and rotary locking ring, the invention also relates to a rotary locking ring for a two-wheeled vehicle frame lock that extends along a circular path and has a blocking structure comprising an abutment configured to be engaged rearward by an adjustable latch of the frame lock body, such that the rotary locking ring is thereby blocked in at least one direction to prevent adjustment along the circular path, wherein the rotary locking ring is characterized in that the abutment is formed by cold forming. Preferably, the entire blocking structure is formed by non-chip forming machining of the rotary locking ring. Except for the end sections at both ends of the longitudinal range of the rotary locking ring, the entire rotary locking ring can be particularly machined only by non-chip forming.

[0038] Based on an embodiment of the frame lock or swivel ring according to the invention, wherein the blocking structure includes at least one web protruding from the swivel ring and having an adjacent portion, the swivel ring can be formed from a bar having a constant cross-section, particularly a circular cross-section, wherein the web protrudes outward beyond the cross-section, particularly beyond the outer contour of the cross-section. In this respect, the web thus protrudes from the swivel ring, wherein, in particular, the web extends outward in a specific direction relative to the center of the cross-section of the swivel ring than the unmachined portion (other than the portion bent into an arc) of the bar from which the swivel ring is formed.

[0039] The swivel lock ring may include a blocking section having a constant cross-section (particularly a circular cross-section) that extends along a portion of the longitudinal range of the swivel lock ring and is configured to engage with the wheel in the closed position of the swivel lock ring, particularly between the spokes of the wheel, thereby preventing wheel rotation. For this purpose, in the closed position of the swivel lock ring, the blocking section is preferably arranged entirely outside the housing of the lock body of the frame lock. In this respect, the web may protrude outward from the swivel lock ring beyond the cross-section of the blocking section, particularly beyond the outer contour of that cross-section. Since the web is formed outside the blocking section, for this purpose, the constant cross-section of the blocking section must, in principle, continue along a circular path to the web.

[0040] According to an advantageous embodiment, the swivel ring comprises at least two webless sections relative to its extent along a circular path. These sections are disposed on opposite sides of the web and have the same constant cross-section, particularly a circular cross-section, wherein the web protrudes outward beyond this cross-section, particularly beyond the outer contour of the cross-section. Thus, the web is arranged between the two webless sections having the same cross-section and protrudes from the swivel ring because the web extends further outward in a particular direction than the two webless sections, especially relative to the center of the swivel ring's cross-section.

[0041] In this respect, the swivel ring may also have other sections comprising the same cross-section. All sections arranged along a circular path between the two webs protruding from the swivel ring, preferably all webless sections of the swivel ring (possibly except for the end sections at both ends of the longitudinal extent of the swivel ring) may particularly have the same cross-section.

[0042] When referring to the cross-section of the swivel ring, unless otherwise stated, in each case the cross-section refers to the longitudinal extent perpendicular to the swivel ring, and due to the arcuate path of the longitudinal extent, the cross-section is oriented substantially radially at least relative to the center of the circular path.

[0043] According to an advantageous embodiment, the web has at least two mutually opposing and parallel side surfaces extending substantially along a circular path, wherein the adjacent portion is formed by an end face of the web, which connects to the side surfaces and is at least substantially perpendicular to the circular path orientation. In this respect, the two side surfaces are preferably aligned parallel to the direction in which the web protrudes from the swivel ring. In this respect, the web can extend along a circular path. Depending on the direction in which the web protrudes from the swivel ring, the side surfaces can therefore have a path curved according to the circular path. However, a relatively short web can also have a straight path tangential to the circular path.

[0044] The side surfaces, transverse to the circular path and transverse to the direction of the protrusion, can be connected to each other via corresponding edges or edge sides of the web, at least where they protrude from the rotating locking ring. In this respect, the edge side may also include the end face through which an abutment is formed. The edge side is preferably oriented at least substantially perpendicular to the side surface. This also applies in particular to the end face forming the abutment. The orientation of the abutment is preferably deviated from the direction perpendicular to the circular path by at most 10°.

[0045] Such a web, comprising two parallel side surfaces, can be formed relatively easily and inexpensively by cold forming. In a segment of the swivel ring (or the material forming the swivel ring) whose length (the length of the segment) corresponds to the length of the web to be formed, the outer region of this segment can be pressed, for example, from opposite directions between the punch and the support, such that the material in this portion is reshaped into a web that bulges outward at least partially perpendicular to these directions. Thus, the two side surfaces of the web are oriented perpendicular to the two opposite directions from which the portion is pressed.

[0046] If the swivel ring has a web comprising the two side surfaces, it can be configured according to an advantageous embodiment such that the transition portion between the end face forming the abutment and the outer side of the web, which connects the two side surfaces and is oriented away from the swivel ring, has a radius of curvature of at most 1 mm, preferably at most 0.5 mm, particularly at most 0.3 mm of the radius of the circular path, and / or at most 1.5%, preferably at most 1%, particularly at most 0.5%. The outer side can be one of the edge sides of the web. Since the outer side is oriented away from the swivel ring, the outer side and the end face forming the abutment can be oriented, in particular, at least substantially perpendicular to each other.

[0047] According to another advantageous embodiment, with respect to the section of the rotating ring that abuts the web along a circular path, preferably with respect to the section of the rotating ring that abuts the web on both sides along a circular path, the side surface of the web extends both further out of and further into the rotating ring, particularly with respect to the surface of the corresponding section that faces outward in the convex direction of the web and extends along a circular path. In this way, the web can not only protrude from the rotating ring but also extend at least partially into the rotating ring, thereby allowing it to be anchored to the rotating ring in a particularly stable manner.

[0048] According to another advantageous embodiment, the corresponding recesses formed in the swivel ring abut two side surfaces of the web. These recesses can, in particular, each be formed as a concave structure in the swivel ring. Furthermore, the recesses may abut the corresponding side surfaces perpendicular to them. In this respect, a portion of the corresponding side surface, particularly a portion of the corresponding side surface extending into the swivel ring as described above, can form the wall of the corresponding recess.

[0049] The two recesses preferably have a constant cross-section, particularly the same cross-section, relative to the direction perpendicular to the side surface. The two recesses can also be considered as single recesses with a constant cross-section, divided (particularly precisely in half) by the web. Besides the web, the recesses facilitate locking of the rotary locking ring. For this purpose, when the rotary locking ring is in its closed position and the latch is in its locked position, it can be configured such that the latch engages not only behind the adjacent surface of the web but also in at least one of the two recesses, preferably in both. In this respect, the latch preferably engages in the corresponding recess, thereby preventing the rotary locking ring from adjusting along a circular path in at least one direction.

[0050] According to another advantageous embodiment, the web may protrude from the swivel ring in a direction perpendicular to the plane of the circular path. Thus, the web protrudes axially from the swivel ring, i.e., parallel to the axis of rotation extending through the center of the circular path and perpendicular to the plane of the circular path. Relative to the center of the swivel ring's cross-section, the web (as already mentioned) preferably protrudes radially outward.

[0051] The material forming the swivel ring can have main fibers extending in a region of the swivel ring that is a central region relative to a direction perpendicular to the circular path and is important for the stability of the swivel ring. Since the web is formed to bulge axially relative to the circular path, damage, particularly interruption, to these main fibers due to the formation of the web can be avoided. Therefore, the stability of the swivel ring is essentially fully maintained despite machining the web. This axial alignment of the webs is particularly advantageous if the blocking structure of the swivel ring includes at least one pair of such webs, wherein the two webs are arranged at the same position along the circular path and bulge from the swivel ring in opposite directions (as will be explained further below), and thus the two webs preferably bulge axially opposite to each other from the swivel ring.

[0052] In order to conceptually distinguish another web protruding from the rotating lock ring that may be provided, the web protruding from the rotating lock ring and whose adjacent portion is engaged by the latch when the rotating lock ring is in its closed position and the latch is in its locked position may also be referred to as the first web, and this designation is not to be construed as referring to a specific minimum, maximum or total number or a specific sorting order or spatial order of the plurality of webs protruding from the rotating lock ring (if applicable).

[0053] According to another advantageous embodiment, the blocking structure includes a plurality of webs projecting from the rotating locking ring, each web having an abutment portion and, in another aspect, can be constructed according to one of the methods described for the first web, wherein, when the rotating locking ring is in a specific position and the latch is in its locked position, the latch engages behind the abutment portion of a corresponding one of the webs, thereby preventing the rotating locking ring from adjusting from the specific position in at least one of two opposite adjustment directions along the circular path. In this respect, in particular, the latch engages behind the corresponding abutment portion relative to the adjustment direction to be blocked.

[0054] A specific position can be the closed position of one or more webs. For example, in the closed position of the rotating lock ring, not only can the adjacent portion of the first web be engaged rearward by the latch in the locked position of the latch, but also the (corresponding) adjacent portions of one or more other webs protruding from the rotating lock ring can be engaged. In this way, the closed position can be secured particularly reliably by the multiple webs protruding from the rotating lock ring.

[0055] However, for one or more webs protruding from the rotating ring, a specific position can also be a position of the rotating ring other than its closed position. In this way, not only in its closed position, but also in one or more other positions, especially in its open position, the rotating ring can be blocked by the latch and thus cannot be adjusted (in at least one direction along the circular path).

[0056] According to an advantageous embodiment, the blocking structure may include another web protruding from the rotating locking ring, this other web having an abutment portion and, in another respect, may be constructed according to one of the methods described for the first web, wherein when the rotating locking ring is in its open position and the latch is in its locked position, the latch engages behind the abutment portion of the other web (relative to the adjustment direction to be blocked), thereby preventing the rotating locking ring from adjusting from the open position. Thus, in particular, at least the rotating locking ring is prevented from reaching the closed position, but preferably, the rotating locking ring is prevented from leaving the open position in the direction of the closed position.

[0057] The other web may be one of the aforementioned webs that protrude from the rotating lock ring. For conceptual distinction, the other web may also be referred to as the second web, and this designation is not to be construed as referring to a specific minimum, maximum, or total number, or a specific arrangement or spatial order, of the multiple webs (if applicable) protruding from the rotating lock ring.

[0058] Therefore, in this embodiment, the same latch that blocks the rotating ring from the open position can also be used to prevent adjustment of the rotating ring from the closed position. This may be advantageous in ensuring that the rotating ring does not adjust accidentally in the closed direction, especially not during two-wheeled vehicle operation, and thus can be engaged with the wheel.

[0059] According to another advantageous embodiment, the blocking structure may include another web protruding from the rotary locking ring, the other web having an abutment portion and, on the other hand, may be constructed according to one of the methods described for the first web, wherein, when the rotary locking ring is in its closed position and the latch is in its locked position, the latch engages behind the abutment portion of the other web (relative to the adjustment direction to be blocked) and thereby blocks adjustment of the rotary locking ring from the closed position in a direction away from the open position (i.e., in a closing direction beyond the closed position). In this respect, in particular, the rotary locking ring can be prevented from deviating from the closed position in this direction.

[0060] The other web may be one of the aforementioned webs protruding from the rotating ring. For conceptual distinction, the other web may also be referred to as the third web, and this designation is not to be construed as referring to a specific minimum, maximum, or total number, or a specific arrangement or spatial order, of the multiple webs protruding from the rotating ring (if applicable). In particular, the presence of the third web does not require the presence of the second web.

[0061] In such an embodiment, the rotating locking ring can thus be fixed in its closed position, thereby preventing adjustment not only in the opening direction but also in the closing direction. This additional fixation may be advantageous in ensuring that the rotating locking ring cannot be forcibly pulled out of the lock body in the closing direction.

[0062] According to another advantageous embodiment, in a blocking structure comprising a plurality of webs protruding from a rotating locking ring, at least two webs may have the same position along a circular path and may protrude from the rotating locking ring in opposite directions relative to the center of the rotating locking ring's cross-section, particularly in the diametrical direction relative to each other, wherein the latch is configured such that when the rotating locking ring is in the corresponding position to be blocked and the latch is in its locked position, the latch engages behind the adjacent portion of one web and the adjacent portion of the other web.

[0063] The fact that these two webs are in the same position means that they are arranged in the same location, at least regionally, along the circular path. Their two adjacent portions can also be in the same location, particularly along the circular path. Their adjacent portions are preferably arranged in a plane.

[0064] The corresponding position to be blocked can be, in particular, the aforementioned specific position of the rotating locking ring, in which the rotating locking ring is blocked by the engagement behind the abutment of the respective one of the two webs and thus cannot be adjusted from that position, and this specific position can be, in particular, the closed position or the open position of the rotating locking ring.

[0065] In order for the latch to cooperate with the adjacent portions of the two webs that protrude from the rotating ring in opposite directions, the latch can be formed in particular as a fork shape having a profile that engages around the rotating ring in a semi-circular manner and extends to two arms that engage behind the adjacent portion of the respective one of the webs in the locked position of the latch.

[0066] The blocking structure may include one or more pairs of webs, each web having the same position along a circular path and protruding from the rotating ring in opposite directions. Specifically, it may be configured such that, for each web protruding from the rotating ring, the blocking structure includes a web arranged at the same position relative to the corresponding web along the circular path and protruding from the rotating ring in opposite directions.

[0067] According to another advantageous embodiment, in a blocking structure comprising a plurality of webs protruding from a rotating locking ring, at least two webs protrude from the rotating locking ring in the same direction, wherein a strip, particularly a strip made of plastic, is arranged at the rotating locking ring, and the strip contacts the outer side of the rotating locking ring facing that direction along a circular path from one of the two webs to the other. In other words, the strip extends at least along a circular path from one web to the other web, and in this respect contacts the outer side of the rotating locking ring. In this respect, the strip preferably contacts the outer side of the rotating locking ring directly. However, generally, at least regionally, a certain gap can be maintained. Furthermore, preferably, the strip or at least a segment of the strip extends along the outer contour of the connecting two webs of the rotating locking ring in a manner following the circular path (particularly in a straight line). A handle for manually adjusting the rotating locking ring can also be provided on the strip, as will be explained further below, and / or the strip can be coupled to one end of the rotating locking ring. Thus, the strip can also be ordered as a connector or a cover.

[0068] The strip is formed separately from the swivel locking ring and is preferably made of plastic. In particular, the strip can be formed as a dimensionally stable and / or as an elastic component. Depending on the shape of the swivel locking ring, the profile of the strip can have an arc shape.

[0069] Specifically, the two webs can be the first web and the second web as described above.

[0070] The strip may extend along a circular path beyond one or two webs. Specifically, in the open position of the rotating lock ring, the strip may extend at least substantially along the longitudinal extent of the rotating lock ring housed within the lock body's outer casing. Preferably, the strip does not extend beyond the outer casing in the closed position of the rotating lock ring. For example, the strip may extend along a circular path at least 120° and / or at most 150°, particularly approximately 135°.

[0071] The fact that the strip contacts the outer side does not preclude it from also contacting or at least being arranged in other areas of the swivel ring. In particular, the strip may engage around the swivel ring at least segmentally in the longitudinal direction from three side surfaces or at an angle greater than 180° (preferably greater than 210°, especially greater than 240°) around the swivel ring.

[0072] Regarding the center of the circular path, the two webs can, for example, both protrude radially inward from the swivel ring, both protrude radially outward, or both protrude in the same axial direction (i.e., perpendicular to the plane of the circular path). Therefore, the outer side of the swivel ring that contacts the strip can be the outer side facing radially inward, radially outward, or axially, and can correspond to the arc-shaped strip area extending from the surface of the swivel ring.

[0073] Because the strip extends along a circular path from one web to the other, it widens the swivel ring in the direction in which the two webs protrude from the swivel ring (at least in the region between the two webs). Preferably, the strip widens the swivel ring by at least the same amount as the amount by which the webs protrude from the swivel ring, such that the strip fills the region between the two webs. This is advantageous for reliably (particularly with as little clearance as possible) guiding the swivel ring into the swivel ring receiver of the lock body, where the swivel ring is at least partially received and adjustably supported. In particular, if the strip widens the swivel ring beyond the amount by which the webs protrude from the swivel ring, the swivel ring can slide along one or more inner walls of the swivel ring receiver with the strip, thus being guided particularly reliably. The at least largely clearance-free guidance of the swivel ring in the swivel ring receiver also helps prevent rattling noise, which could otherwise occur during the operation of a two-wheeled vehicle.

[0074] Advantageously, a handle for manually adjusting the rotary locking ring or at least one fastening lug for fastening such a handle to the strip can be arranged or formed (particularly molded to the strip). In this respect, the handle or fastening lug preferably protrudes from a plane of the strip perpendicular to the circular path. However, in general, different orientations are also conceivable. In particular, the handle or fastening lug may also protrude radially outward from the center of the circular path relative to the strip.

[0075] Providing a handle at the strip, rather than forming or securing it directly to the swivel ring, helps to prevent damage to the material structure of the swivel ring. In particular, the handle or its fastening lug does not need to be welded to the swivel ring.

[0076] According to an advantageous embodiment, the strip has a side surface that is aligned at least substantially with both the side surface of one of the two webs (particularly one of the side surfaces) and the side surface of the other of the two webs (particularly one of the side surfaces). In this respect, the side surface of the strip may define the strip in the circumferential direction at least in the region between the two webs around the longitudinal extent of the rotating lock ring.

[0077] Due to the alignment, the three side surfaces of the two webs and the strip can form a continuous path, potentially away from the corresponding gaps at the two transition sections. In this respect, these three side surfaces can be specifically arranged in a plane, or they can form a curved path corresponding to the route of a circular path.

[0078] In this respect, the side surface can be specifically oriented in a direction corresponding to the adjustment of the latch from its locked position to its unlocked position. The latch can be pre-tightened in the opposite direction, i.e., pre-tightened from the unlocked position to its locked position, and after the latch has moved to its unlocked position to release the locking position of the rotating lock ring, the latch can slide along the path formed by the side surface pre-tightened against the path while the rotating lock ring is being adjusted. In this way, during the adjustment of the rotating lock ring, the latch can be held in its unlocked position by the strip, or at least in a position that does not obstruct the rotating lock ring.

[0079] According to another advantageous embodiment, the strip is fastened to the swivel ring in a form-fitting manner, particularly by a latching mechanism. In this respect, the strip can form a form-fitting with at least one of a plurality of webs protruding from the swivel ring (if applicable). The strip can particularly be captured between two webs, wherein the strip extends at least between said two webs such that the strip is uniquely fixed relative to the swivel ring along a circular path, i.e., the strip cannot move relative to the swivel ring along the circular path (but only together with the swivel ring). The strip is preferably fastened to the swivel ring in a form-fitting manner in any spatial direction.

[0080] Furthermore, the object of the present invention is achieved by a method for manufacturing a rotary lock ring for a frame lock, particularly a rotary lock ring as described above, which can be constructed in one or more of the aforementioned manner, wherein the method comprises at least: providing a metal wire extending along a longitudinal range; bending the metal wire into an arc shape; and forming a web protruding from the metal wire by cold forming, wherein, in such a section of the longitudinal range of the metal wire (the length of which (i.e., the length of the section along the longitudinal range) corresponds to the length of the web to be formed), a portion of the section facing a first transverse direction perpendicular to the longitudinal range is pressed from a second transverse direction perpendicular to the longitudinal range and the first transverse direction and in a direction opposite to the second transverse direction, such that two recesses are pressed into the metal wire, and the material thereby displaced is reshaped into a web protruding from the metal wire between the two recesses in the first transverse direction. A punch and a support against which the punch presses can be used, for example, for cold forming, wherein the portion is clamped between the punch and the support and pressed against the support by the punch (and, according to the reaction principle, also pressed against the punch by the support).

[0081] In this respect, the order of the steps of bending and forming the web is not fixed relative to the order mentioned above. During the extrusion of a portion of the longitudinal range of the wire, the wire can therefore still be stretched, particularly in a straight manner, or may have already been bent into an arc shape.

[0082] Furthermore, the object of the present invention is achieved by a method for manufacturing a frame lock, particularly a frame lock as described above, which can be constructed in one or more of the aforementioned manner, wherein the method comprises at least: performing the method for manufacturing a rotary lock ring for the frame lock; and assembling the frame lock using the manufactured rotary lock ring. The assembly may particularly include a rotary lock ring that is at least partially inserted into the housing of the lock body of the frame lock and connected to the housing at one end along its longitudinal direction.

[0115] Figure 1 An embodiment of a frame lock 11 according to the invention is shown. 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 extending from the corners of the parallelepiped shape.

[0116] An invisible locking device in the form of a lock cylinder is housed in the central portion, along with a latch 21 connected to the locking device (see...). Figure 6 and Figure 7 The locking device can be actuated in a conventional manner using only the key 23 associated with it. In this respect, the latch 21 is coupled to the locking device, allowing the latch to be adjusted between an unlocked and locked position by using the key 23 to drive the locking device. In this respect, there is a particularly clear relationship between the corresponding positions of the latch 21 and the corresponding rotational positions of the key 23.

[0117] The frame lock 11 also has a rotating locking ring 25 that extends along a circular path and is at least partially housed in the housing 15, i.e., housed in a rotating locking ring receiver that extends through the first branch 17 and into the central portion of the parallelepiped shape of the lock body 13. The rotating locking ring 25 is supported relative to the lock body 13 in this respect, allowing it to be adjusted between an open and closed position along its longitudinal extent (i.e., along the circular path). The rotating locking ring 25 has a constant cross-section (which is circular in the illustrated example), but it can typically also have another shape, such as a regular polygon. In this respect, the segments with the constant cross-section together form the (largest) main portion of the longitudinal extent of the rotating locking ring 25, for example, more than 80%, and particularly more than 90%.

[0118] In the closed position, the swivel ring 25 extends from the first branch 17 with its free end 27 and extends into the second branch 19, connecting the two branches 17 and 19, the lock body 13, and the swivel ring 25 to form a closed loop. In this way, for a corresponding arrangement of the frame lock 11 on the frame of a two-wheeled vehicle (not shown), the swivel ring 25 can engage the wheels passing through the spokes of the two-wheeled vehicle, thereby preventing wheel rotation. The section of the swivel ring 25 arranged outside the housing 15 in the closed position forms a blocking section 29 of the swivel ring 25, which has the circular cross-section from beginning to end. The blocking section 29 extends along the circular path within an angular range of approximately 60°.

[0119] Conversely, in the open position, the swivel lock 25 is fully contained within the housing 15, or only slightly protrudes from the first branch 17 of the housing 15 at its free end 27, thus maintaining free space between the two branches 17, 19, within 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 25 releases the wheels of the two-wheeled vehicle to allow them to rotate.

[0120] If the rotating locking ring 25 is not obstructed by the latch 21 and cannot be adjusted, the rotating locking ring 25 can be manually moved from the open position to the closed position via the handle 31; conversely, it returns from the closed position to the open position along the circular path, which corresponds to the rotation of the rotating locking ring 25 about the center M of the circular path. For this purpose, the handle 31 is coupled to the rotating locking ring 25 and extends perpendicularly to the plane of the circular path (along which the rotating locking ring 25 extends) through a slot 33 formed in the first branch 17. The slot 33 has an arcuate path in this respect, wherein the arcuate shape of the slot 33 corresponds to the path of the circular path, and in particular is coaxial with the circular path, i.e., having the same center M.

[0121] Figure 1 The frame lock 11 is shown in a view obtained from one side of the circular path extending from the rotating locking ring 25 perpendicular to the frame lock 11. Figure 2 and Figure 4 In the middle, the direction of observation is exactly the opposite.

[0122] exist Figure 2 The rotating lock ring 25 of the frame lock 11 is shown separately. In this respect, it can be seen that the free end 27 of the rotating lock ring 25 has a tapered chamfer. The rotating lock ring 25 is fixed to the lock body 13 by means of its end opposite to the free end 27. In this respect, this end forms the connecting end 35 of the rotating lock ring 25. At the connecting end 35, the rotating lock ring 25 flattens on both sides of a plane perpendicular to the circular path, and in particular has a hole 37 for connecting to the lock body 13, which extends perpendicularly through the rotating lock ring 25 to the plane of the circular path.

[0123] In order to be prevented from being adjusted between the open and closed positions by being blocked by the latch 21, the rotary lock ring 25 has a blocking structure comprising a plurality of webs 39. Each of these webs 39 protrudes from the rotary lock ring 25 at least partially perpendicular to a plane perpendicular to the circular path. In this respect, each web 39 specifically protrudes above the circular cross-section of the rotary lock ring 25, particularly along the circular path adjacent to the corresponding web 39. Thus, the webs 39 extend outward beyond the outer contour of this cross-section.

[0124] The web is formed by cold forming. For this purpose, the bar (the rotating locking ring 25 is formed from the bar and has the constant cross-section) is either bent into an arc shape (i.e., with a still straight path) or with an already arc-shaped path, sandwiched between a punch and a support in a section of the bar's longitudinal length corresponding to the length of the web 39 to be formed. A portion of this section facing the direction in which the web 39 is to protrude is pressed from the opposite direction by the punch and support perpendicular to that direction and perpendicular to the longitudinal length of the bar, such that the two recesses 41 are pressed into the bar and the material thereby displaced is reshaped into the web 39, which protrudes from the bar between the two recesses 41 in that direction.

[0125] As a result of this design, the corresponding web 39 has two parallel side surfaces 43 that are oriented radially outward or inward relative to the center M of the circular path and thus extend substantially tangentially to the circular path. Relative to the center of the cross-section of the rotating ring 25, and compared to the surface of the section of the web 39 adjacent to the rotating ring 25 along the circular path, the side surfaces 43 extend both outside and into the rotating ring 25, such that the portion of the corresponding side surface 43 extending into the rotating ring 25 forms the sidewall of the recess 41 adjacent to the corresponding side surface 43.

[0126] As in Figure 3 As can be seen in particular, for some webs 39, the two side surfaces 43 of the corresponding web 39 are connected by an edge side that is oriented perpendicular to the side surfaces 43 and thus substantially radially toward the center M of the circular path, and this edge side includes two end faces 45 facing opposite directions along the circular path and an outer surface 47 perpendicular to the circular path toward the direction in which the web 39 protrudes from the swivel ring 25. The transition between the end faces 45 and the outer surface 47 is rounded in each case because they are formed by cold forming; however, the side surfaces 43 preferably have a relatively small radius of curvature, particularly not exceeding 0.3 mm.

[0127] The latch 21 and the rotating locking ring 25 are arranged opposite to each other such that, in the locked position, the latch 21 is at least partially located in the movement path of the web 39, through which the web 39 will pass unimpeded as the rotating locking ring 25 is adjusted along the circular path. When the latch 21 is in its locked position, the latch 21 thus engages behind the one of the end faces 45 of the web 39 closest to the direction of adjustment of the rotating locking ring 25. When the rotating locking ring 25 is adjusted along this direction, the end face 45 thus abuts the latch 21, thereby preventing further adjustment of the rotating locking ring 25 along this direction. In this respect, the end face 45 forms an abutment portion 49 of the blocking structure of the rotating locking ring 25, which is oriented at least substantially perpendicular to the path of the circular path. In this respect, the small radius of curvature facilitates that the rotating locking ring 25, including the corresponding abutment portion 49, cannot be pushed through the latch 21.

[0128] In relative to Figure 2 and Figure 4 In the outward direction of the image plane, a total of three webs 39 protrude from the rotating locking ring 25, namely the first web 39.1, the second web 39.2 and the third web 39.3.

[0129] In this respect, the first web 39.1 is arranged along the longitudinal range of the rotating locking ring 25, such that when the rotating locking ring 25 is in its closed position and the latch 21 is adjusted to its locked position, the latch 21 engages alongside the first web 39.1 in its movement path. Thus, the end face 45 of the first web 39.1 facing the opening direction along the circular path forms an abutment 49 adjacent to the latch 21, thereby preventing the rotating locking ring 25 from deviating from its closed position in the opening direction, where the rotating locking ring 25 can typically be adjusted from its closed position to its open position (in...). Figure 2 and Figure 4 In the middle, the opening direction corresponds to the counterclockwise direction.

[0130] The second web 39.2 is arranged along the longitudinal range of the rotating locking ring 25 such that when the rotating locking ring 25 is in its open position and the latch 21 is adjusted to its locked position, the latch 21 engages alongside the second web 39.2 in its movement path. Thus, the end face 45 of the second web 39.2 facing the closing direction along the circular path forms an abutment 49 adjacent to the latch 21, thereby preventing the rotating locking ring 25 from deviating from its open position in the closing direction through the engagement of the latch 21 with the abutment 49. In the closing direction, the rotating locking ring 25 can typically be adjusted from its open position to its closed position (in... Figure 2 and Figure 4 In the middle, the closing direction corresponds to the clockwise direction.

[0131] The third web 39.3 is arranged along the longitudinal range of the rotating locking ring 25 such that when the rotating locking ring 25 is in its closed position and the latch 21 is adjusted to its locked position, the latch 21 engages next to the third web 39.3 in its movement path. Thus, the end face 45 of the third web 39.2 facing the closing direction along the circular path forms an abutment 49 adjacent to the latch 21, thereby preventing the rotating locking ring 25 from being adjusted beyond the closed position in the closing direction through the engagement of the latch 21 with the abutment 49.

[0132] Therefore, in the closed position of the rotating locking ring 25, the latch 21 engages in its locked position between the first web 39.1 and the third web 39.3, particularly between the adjacent portions 49 of these two webs 39.1 and 39.3 (see...). Figure 6 This causes the rotating locking ring 25 to be blocked along the circular path in both adjustment directions (open and closed). Due to the additional obstruction in the closed direction, the rotating locking ring 25 is fixed and will not be pulled off the lock body 13 in its closed position.

[0133] The rotating locking ring 25 also has a fourth web 39.4, which can be... Figure 3 and Figure 5 As seen in the image, the fourth web 39.4 has the same position as the first web 39.1 along the circular path but in the opposite direction (i.e., perpendicular to the path). Figure 2 and Figure 4 The rotating locking ring 25 protrudes from the image plane described in the image. Furthermore, the rotating locking ring 25 also has a fifth web 39.5, which has the same position as the second web 39.2 along a circular path, but protrudes from the rotating locking ring 25 in the opposite direction. The fifth web 39.5 in... Figure 1 The handle 31 can be seen through the slot 33. The fourth web 39.4 and the fifth web 39.5 are not only formed in substantially the same manner as the first web 39.1 or the second web 39.2 (except for the opposite orientation), but also have the same function, namely, cooperating with the latch 21 to prevent the rotating locking ring 25 from deviating from the closed position in the opening direction or from deviating from the open position in the closing direction, so that the reliability of the rotating locking ring 25 being locked in the corresponding position is further improved by the fourth web 39.4 and the fifth web 39.5.

[0134] The frame lock 11 also includes a strip 51 made of plastic, which is arranged at the rotating lock ring 25 and is particularly suitable for use with plastic. Figures 4 to 7 As seen in the image, the strip 51 engages with a hole 37 at the connecting end 35 of the swivel ring 25 via a pin 53 formed thereon, and extends from there across most of the longitudinal extent of the swivel ring 25, particularly extending at least substantially to the blocking section 29. In this respect, the strip 51 has a substantially C-shaped cross-section at least partially, i.e. particularly in the section between the first web 39.1 and the second web 39.2, and thus covers the swivel ring 25 both radially inward relative to the circular path and in both axial directions (i.e., directions perpendicular to the plane of the circular path).

[0135] A portion of the strip 51 contacts the surface of the swivel ring 25 along its outer contour, which extends from the first web 39.1 along a path corresponding to the circular path to the second web 39.2. In this respect, the height of the strip 51 (i.e., the length of the strip 51 extending radially to the center of the cross-section of the swivel ring) corresponds to the amount by which the first web 39.1 and the second web 39.2 protrude from the swivel ring 25, such that the strip 51 fills the area between the two webs 39.1 and 39.2. The side surfaces 55 of the strip 51 (which define the strip 51 in this area in the circumferential direction around the swivel ring 25) are aligned with the two side surfaces 43 of the two webs 39.1 and 39.2, which face radially outward relative to the center M of the circular path, such that the three side surfaces 49, 55 form a substantially continuous path.

[0136] The strip 51 (except for its end which is connected to the connecting end 35 of the rotating locking ring 25 via a pin 53) is symmetrical with respect to a plane parallel to the plane of the circular path. Therefore, the strip 51 also utilizes an orientation relative to... Figure 4 The image plane points inward and therefore in Figure 4 A portion not visible in the middle fills the area between the fourth web 39.4 and the fifth web 39.5, and has a side surface 55 that defines the band 51 circumferentially in this area, wherein the side surface 55 is aligned with the two side surfaces 43 of the two webs 39.4 and 39.5 that face radially outward relative to the center M of the circular path and thus forms a substantially continuous path with them (see...). Figure 5 ).

[0137] Due to the length of the strip 51, from the first web 39.1 to the second web 39.2, and from the fourth web 39.4 to the fifth web 39.5, the strip 51 forms a form fit with these webs 39 at least relative to the circular path. Furthermore, the strip 51 can be locked (i.e., through a resiliently reversible form fit) to the swivel ring 25 and can be clamped between the webs 39 in this way, preventing it from moving relative to the swivel ring 25 along the circular path. In this way, the material structure of the swivel ring 25 is not damaged by the strip 51 and the handle 31 disposed thereon being fastened to the swivel ring 25. To fasten the handle 31 to the strip 51, the strip 51 has a fastening protrusion integrally formed (i.e., molded onto the strip 51). This fastening protrusion extends perpendicular to the circular path and is therefore perpendicular to... Figure 4 The image plane extends into the image plane and therefore cannot be seen.

[0138] Figure 6 and Figure 7 The engagement of the latch 21 with the rotating locking ring 25, particularly its web 39 and the strip 51, is shown.

[0139] Figure 6 The diagram shows the state in which the rotating locking ring 25 is in its closed position and the latch 21 is in its locked position. In this state, the latch 21 engages with the rotating locking ring 25 in the opening direction (i.e., in the direction toward the open position) behind the abutment portion 49 of the first web 39.1 and the abutment portion 49 of the fourth web 39.4, which is oriented opposite to the first web 39.1 (see [reference]). Figure 7 This prevents such adjustment. Simultaneously, the latch 21 in this state also engages with the rear of the adjacent portion 49 of the third web 39.3 relative to the adjustment in the closing direction (see...). Figure 7 Therefore, this regulation is also prevented.

[0140] Because the latch 21 is forked and has a profile that engages around the rotating ring 25 according to its cross-section (i.e., in a semi-circular manner in the example shown), this allows the latch 21 to simultaneously cooperate with webs 39.1 and 39.3 protruding from the rotating ring 25 in a direction perpendicular to the circular path and with web 39.4 protruding from the rotating ring 25 in the opposite direction. Therefore, the latch 21 has two arms, with the profile extending to one or more arms on one side and thus the arms can engage with one or more corresponding webs 39 on opposite sides of the rotating ring 25 (axially relative to the circular path), and the arms can specifically engage behind the abutment 49 of the corresponding webs 39.

[0141] Figure 7 The image shows a state where the latch 21 has been moved to its unlocked position, causing the latch 21 to release the rotating locking ring 25 for adjustment along a circular path. Figure 6 Compared to the closed position shown, in Figure 7 In the illustrated state, the rotating locking ring 25 is adjusted a certain distance in the opening direction, but has not yet reached the open position. In this regard, the latch 21 contacts the side surfaces 55 of the strip 51 on both sides of the rotating locking ring 25 using the arm, wherein the side surfaces 55 define the strip 51 in the peripheral direction around the longitudinal extent of the rotating locking ring 25. During the adjustment of the rotating locking ring 25 along a circular path, the latch 21 can thereby slide along both sides of two consecutive paths, wherein the two consecutive paths are defined by one side surface 55 of the strip 51 and the side surfaces 43 of the first web 39.1 and the second web 39.2, or by the other side surface 55 of the strip 51 and the side surfaces 43 of the fourth web 39.4 and the fifth web 39.5.

[0142] Thus, during the adjustment from the closed position to the open position and from the open position to the closed position, the latch 21 is held in its unlocked position and therefore does not need to be adjusted back to the unlocked position before reaching the corresponding position, allowing the corresponding one of the web plates 39 to be guided through the latch 21. If the locking device is configured to be coupled to the latch 21 such that the key 23 can only be removed from the locking device when the latch 21 is in its locked position, this simultaneously ensures that the key 23 cannot be removed in the intermediate position between the open and closed positions of the rotating lock ring 25.

[0143] Therefore, the described exemplary embodiments generally show that the design of the swivel lock ring 25 according to the invention (which includes the swivel lock ring 25 including the abutment portion 49 formed by cold forming and / or formed at the web 39 protruding from the swivel lock ring 25) allows for various advantageous functions, wherein such a swivel lock ring 25 can be manufactured simply and inexpensively (especially also automatically), with little compromise in its material structure and thus has a particularly stable structure, making it suitable for securing two-wheeled vehicles in a particularly reliable manner.
