Description

[Technical Field]

[0001] This invention relates to a frame lock for a two-wheeled vehicle. [Previous Technology]

[0002] Generally speaking, frame locks differ from portable two-wheeler locks because frame locks are fixedly 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 rings of the frame lock can be selectively adjusted to engage between the spokes of the two-wheeler's wheels, thereby preventing travel with the two-wheeler. The rings are conveniently secured in this position by a latch of the frame lock, ideally adjustable at least by the lock cylinder of the frame lock or another locking device, which the user must actuate with a secret code such as a key. Typical designs of the rings are, on the one hand, the construction of a pivot ring with a straight path, and on the other hand, the construction of a rotating ring with an arcuate path.

[0003] Specifically, the frame lock may include a lock body and a rotating ring, the lock body including a latch, the rotating 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 ring releases the wheels of a two-wheeled vehicle to rotate, and in the closed position, the rotating ring prevents the wheels from rotating, wherein the rotating ring has a blocking structure including an adjacent portion. The latch is adjustable between an unlocked position and a locked position, and wherein when the rotating ring is in its closed position and the latch is in its locked position, the latch engages behind the adjacent portion, thereby preventing the rotating ring from adjusting into the open position.

[0004] The stability of the rotating ring is a decisive factor affecting the reliability of the frame lock. Therefore, to prevent the frame lock from being opened by force, the rotating ring must be particularly robust. At the same time, efforts should be made to manufacture the rotating ring as cost-effectively and with the greatest possible degree of automation. In this regard, the rotating ring is preferably formed from a particularly hard and strong material, such as a hardened metal. In particular, the rotating ring can be made from a rod material such as metal wire.

[0005] In order to be adjustable relative to the lock body, the rotating ring can be at least partially housed in the housing of the lock body, particularly in a rotating ring receiver formed in the housing, and can be movably supported in the rotating ring receiver. In this respect, the rotating ring receiver also serves to guide the rotating ring, so that the rotating ring can be adjusted at least substantially only along a circular path. In particular, due to the blocking structure formed on the rotating ring, the rotating ring can have a raised portion and / or a recessed portion extending along its longitudinal direction, so that in some cases, the rotating ring may not contact the inner wall surface of the rotating ring receiver, or may only contact the inner wall surface of the rotating ring receiver in a portion extending longitudinally and be guided at the inner wall. To prevent the rotating ring from tilting or getting stuck in the rotating ring receiver, a certain gap is usually also provided between the outer periphery of the rotating ring and the inner periphery of the rotating ring receiver. For these reasons, the rotating ring can usually make small movements laterally to its longitudinal direction in the rotating ring receiver, and in doing so, may impact the edge of the rotating ring receiver. In particular, this can occur during a trip using a two-wheeled vehicle equipped with a frame lock, and can then result in a noticeable and disturbing rattling noise.

[0006] To enable the actuation of the rotating ring, i.e., to manually adjust the rotating ring between its open and closed positions, a handle is typically provided on the frame lock and fastened to the rotating ring. The handle extends outward from the frame lock, allowing it to be gripped and moved about the center of a circular path, thereby adjusting the rotating ring accordingly along the circular path. In this respect, the handle or a fastening lug to which the handle is fastened can be, for example, welded to the rotating ring for a stable connection. Alternatively, the handle or fastening lug can also be screwed onto the rotating ring. However, fixing to the rotating ring in this type may result in damage to the material structure, thereby compromising the mechanical stability of the rotating ring. [Summary of the Invention]

[0007] One object of this application is to provide a frame lock or frame lock system including a low-noise frame lock for a two-wheeled vehicle, wherein the rotating ring of the frame lock or frame lock system is particularly stable and easily actuated in this respect, the frame lock or frame lock system is also flexible in use, and the frame lock or frame lock system can be manufactured in a manner that is as automated as possible.

[0008] This objective is achieved by the frame lock and frame lock system described below.

[0009] The frame lock for a two-wheeled vehicle according to this application includes a lock body and a rotating ring device. The lock body has a latch, and the rotating ring device includes a rotating ring and a belt. In this respect, the rotating 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 ring releases the wheels of the two-wheeled vehicle to rotate, and in the closed position, the rotating ring blocks the wheels from rotating.

[0010] The swivel ring is preferably made of metal, while the belt is preferably made of plastic. The swivel ring is preferably formed of a rod material, particularly a metal wire such as steel wire, wherein the rod material preferably has a fixed cross-section, particularly a circular cross-section. This cross-section may be the standard cross-section of the swivel ring, having this cross-section along most of its longitudinal extension and / or at least along a blocking portion disposed outside the lock body, particularly outside the lock body housing in the closed position of the swivel ring, such that in its closed position, the swivel ring can engage with the blocking portion into the wheel of a two-wheeled vehicle, thereby preventing the wheel from rotating. The diameter of the circular path may, for example, be in the range of 10 cm to 15 cm, and may reach, for example, approximately 13 cm. In the cross-section, the swivel ring may have a diameter on the order of several millimeters to several centimeters. For example, the diameter of the cross-section may be at least on average about 8 mm or 9 mm. Due to the range along the circular path, the rotating ring has an arcuate shape extending over a specific portion of the circular closed circular path, for example, extending over 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°.

[0011] Since the rotating 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, and conversely, from the closed position to the open position and enter the open position in the opening direction opposite to the closing direction. However, it is therefore not excluded that the rotating ring can also be adjusted in another way, particularly in the closing direction other than the closed position and / or in the opening direction other than the open position.

[0012] When adjusting the rotating ring along the circular path, the rotating ring moves along the circular path in its arc-shaped longitudinal extension such that it does not leave the circular path, but only extends over a portion of the circular path, i.e., changes relative to its position rather than relative to its angular range. In this respect, the adjustment of the rotating ring corresponds to rotation 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.

[0013] The adjustability of the rotating ring along a circular path is a fundamental adjustability, which in particular can be caused by the corresponding support of the rotating ring at the lock body. However, this adjustability is not necessarily permanent, but can be blocked by the latch, particularly by the ability to fix the rotating ring in one or more different specific positions via the latch. The rotating ring can preferably 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 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 the adjustment.

[0014] The circular path may extend partially through the lock body of the frame lock, such that the rotating ring may extend partially into or through the lock body and cooperate with the latch within the lock body in this respect. In this respect, the latch is preferably arranged entirely within the housing of the lock body to make it as inaccessible as possible from the outside. The rotating ring may also be partially received within the housing of the lock body. In particular, the rotating ring may be at least partially received in and movably supported in a rotating ring receiver formed in the lock body, i.e., adjustable relative to the lock body between an open position and a closed position.

[0015] In the closed position, the rotating ring preferably extends out of the lock body, particularly out of the housing of the lock body, and then at least its free end returns to the lock body, particularly extending into the housing, such that the lock body and the rotating ring preferably form a closed loop in the closed position. In this way, rotation of the corresponding wheel can be stopped particularly reliably. Conversely, in the open position, the rotating 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 housing.

[0016] In the closed position of the swivel ring, when the frame lock is properly mounted on the two-wheeled vehicle, the swivel ring naturally blocks only the rotation of the wheels of the respective two-wheeled vehicle. In other words, the frame lock is configured to be arranged on the two-wheeled vehicle such that the swivel ring blocks the wheels of the two-wheeled vehicle from rotating in their closed position (particularly by engaging through the wheels) and releases the wheels to rotate in their open position.

[0017] According to this application, the rotating 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 ring is in its closed position and the latch is in its locked position, the latch engages behind the adjacent portion, thereby blocking the adjustment of the rotating ring and preventing it from entering the open position.

[0018] In particular, the latch can be adjustable relative to the housing of the lock body between an unlocked position and a locked position. This adjustment can be, for example, a linear displacement. Preferably, the latch can be adjusted only by a locking device disposed at, and particularly within, the lock body, preferably in the form of a lock cylinder, the latch being connected to the lock body, for example, by a clamp, and the latch being actuated only by the key associated therewith.

[0019] The adjustability of the latch is also a fundamental adjustability, which does not need to be permanent but can be specifically dependent on the corresponding position of the rotating ring. The latch can preferably 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, at least when the rotating ring is in its closed position. Additionally, particularly when the rotating 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 from the locked position to the unlocked position and into the unlocked position.

[0020] Therefore, the rotating 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 ring. If the adjacent portion is oriented at least substantially perpendicular to the direction of movement to be blocked, i.e., perpendicular to the circular path of the rotating ring, the adjustment of the blocking rotating ring along the circular path is particularly reliable, and therefore this is the preferred option.

[0021] The adjacent portion is preferably, but not necessarily, formed as an adjacent surface, i.e., formed as a plane. The adjacent portion may also typically be formed by the edge or outline of a barrier structure.

[0022] The blocking structure can be formed in many different ways. A commonly conceivable manner is that the blocking structure includes a cut or notch in the rotating ring, wherein the cut or notch may 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 may be formed as a sidewall of such a cut or notch. However, the adjacent portion may also be formed by a sidewall of a structure protruding from the rotating ring.

[0023] The blocking structure may have multiple adjacent portions, each of which may be engaged at the rear by a latch to fix different positions of the rotating ring in at least one adjustment direction and prevent it from deviating from the corresponding position. In this respect, multiple adjacent portions may be used to fix the same position relative to the same adjustment direction or mutually opposite adjustment directions.

[0024] The engagement of the latch behind the adjacent portion should be understood as relating to the adjustment of the rotating ring to be blocked. In this respect, in particular, if the latch is in its unlocked position and the rotating ring is adjusted along the circular path in the direction of adjustment to be blocked, the latch engages transversely to the circular path into the movement path of the adjacent portion, through which the adjacent portion will pass.

[0025] When the rotating 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 between it and the adjacent portion, for example, less than 1 mm, particularly a few hundred micrometers. Therefore, the rotating ring is advantageously fixed and will not deviate from the closed position in the direction of the open position at all. However, the latch may also typically have a larger gap from the adjacent portion, such that the rotating ring can be practically adjusted from the closed position to a distance corresponding to this gap, but in any case, it is blocked from reaching a position where the rotating ring will no longer reliably prevent the wheel from rotating.

[0026] In addition to the rotating ring, the rotating ring device also includes the belt. According to this application, the belt is disposed on the rotating ring, extends along a circular path, and is configured such that at least a portion of the belt extending longitudinally along the rotating ring and at least a portion of the periphery of the rotating ring cover the rotating ring.

[0027] In this respect, in particular, the belt is arranged on the rotating ring such that the belt is adjusted together with the rotating ring when the rotating ring is adjusted. In this respect, the rotating ring device formed by the rotating ring and the belt forms a functional unit of the frame lock. During the assembly of the frame lock, at least after the belt has been arranged on the rotating ring, the rotating ring and the belt can only move together, that is, there is no relative movement between them.

[0028] Therefore, the corresponding position of the rotating ring also represents the corresponding position of the belt and the entire rotating ring device. In particular, in the open position of the rotating ring, the belt and the rotating ring device as a whole are also in the open position, and in particular, in the closed position of the rotating ring, the belt and the rotating ring device as a whole are also in the closed position, and can be adjusted between these positions.

[0029] Since the belt at least partially covers the rotating ring along its longitudinal direction, the belt extends along the circular path in a manner corresponding to the rotating ring. Thus, in particular, the belt may have at least a substantially arcuate route, along which the belt may at least partially have a fixed cross-section.

[0030] Along the circular path, the band may extend, for example, at least 120° and / or at most 150°, particularly approximately 135°. The longitudinal extension of the band, i.e., its extent along the circular path, may be particularly limited to the support portion disposed within the lock body, especially within the housing of the lock body, both in the closed position and the open position of the rotating ring (and all positions in between). In this respect, the band preferably extends in the open direction to the corresponding end of the rotating ring. In the opposite closing direction, the band preferably extends over at least a majority of the support portion. In particular, the band may extend at least substantially over the entire support portion.

[0031] In this respect, the belt extends not only along the circular path but also in the circumferential direction of the route around the circular path, thereby covering at least a portion of the periphery of the rotating ring, wherein the periphery corresponds to a corresponding cross-section of the rotating ring in a plane orthogonal to the route of the circular path. In this way, the belt can be engaged around the rotating ring, particularly, more or less depending on the position along its longitudinal direction. This can contribute to a particularly stable arrangement of the belt at the rotating ring.

[0032] To cover the rotating ring, the belt may contact the rotating ring in the area it covers, particularly in surface contact with the rotating ring. Due to this coverage, the belt can provide protection for the rotating ring, such as preventing mechanical damage, dirt, and / or moisture. Additionally, the free space between the rotating ring and one or more inner walls of the rotating ring receiver of the lock body can be filled by the belt, allowing the rotating ring to be guided substantially without gaps within the rotating ring receiver, thereby avoiding rattling noise, wherein the rotating ring assembly can be at least partially accommodated in this free space and movably supported. The design of the belt, made of plastic, can also contribute to this, with the plastic being specifically selected or formed according to its elasticity and / or surface properties, allowing the belt to slide easily along the corresponding inner wall of the rotating ring receiver. The belt can also be used to connect the rotating ring to the handle, which will be explained further below.

[0033] Due to these different functions, the belt may also be specifically designated as a “cover”, “track”, especially a “guide rail”, or a “connector”.

[0034] According to this application, the belt is also provided to extend more than 180° in the circumferential direction around the rotating ring, preferably more than at least 210°, and particularly more than about 225°.

[0035] The angular range is defined relative to the center of the cross-section of the rotating ring, which preferably corresponds to the centroid region of the cross-section. Specifically, the cross-section may be a cross-section of the rotating ring at a corresponding position extending longitudinally along the rotating ring, or, if desired, a standard cross-section of the rotating ring that can conceptually extend to a corresponding position along a circular path. In particular, the cross-section may be circular.

[0036] The belt has the range at least generally in the circumferential direction, that is, the belt does not necessarily extend beyond the angular range in the circumferential direction around the rotating ring at a single position along its longitudinal direction, but can extend as far as possible in one circumferential direction at one position and as far as possible in the opposite circumferential direction at another position, wherein the angle between these ranges is equal to or greater than 180°, preferably at least 210°, and particularly about 225°.

[0037] However, in one or more longitudinally extending regions of the belt, the belt preferably extends more than 180°, preferably more than at least 210°, and particularly more than about 225°, along the entire corresponding region in the circumferential direction around the rotating ring. In other words, it applies to every location along the longitudinal extension of the belt within a corresponding region of these regions, where the belt extends beyond the said angular range in the circumferential direction around the rotating ring.

[0038] The portion of the belt extending more than 180°, preferably more than at least 210°, and particularly more than about 225° in the circumferential direction around the rotating ring, preferably together have a length greater than half the longitudinal extension of the belt (i.e., the range along the circular path). Particularly preferred is that the longest portion of these portion of the belt extends more than half the longitudinal extension of the belt.

[0039] Typically, the rotating ring covered by the band may have interruptions in the circumferential direction, i.e., it may be distributed across multiple individual portions that together extend more than 180°, preferably more than at least 210°, and particularly more than about 225° around the periphery of the rotating ring. However, the rotating ring is preferably covered by portions of a band that are continuous in the circumferential direction within the said angular range, i.e., without interruption.

[0040] Because the belt extends more than 180° in the circumferential direction around the rotating ring, it covers more than half of the circumference of the rotating ring and surrounds the engaging rotating ring from at least three side surfaces. In other words, the belt thus covers the rotating ring with respect to at least three directions, two of which are opposite to each other, and the third is perpendicular to the rotating ring, wherein these directions are oriented transversely to the longitudinal extension of the belt or the rotating ring, and in particular, can be radially oriented relative to the said center of the cross-section of the rotating ring. Due to this surrounding engagement, the belt can be arranged particularly reliably at the rotating ring. In addition, the belt can support the rotating ring on most of the circumference of the rotating ring relative to the rotating ring receiver in such a way that the rotating ring is guided particularly reliably in the rotating ring receiver.

[0041] According to an advantageous embodiment, the belt at least partially covers the rotating ring in a direction perpendicular to the plane of the circular path, at least partially covers the rotating ring in a direction opposite to that direction, and at least partially covers the rotating ring in a direction facing or away from the center of the circular path. The area of ​​the belt covering the rotating ring in one of said directions may overlap along the circular path. The guide rail preferably covers the rotating ring in one or more portions of its longitudinal extension in all three directions, particularly in the aforementioned portions. In this respect, coverage in a particular direction should be understood as such that the belt is arranged to be adjacent to the rotating ring in that direction, so that, viewed from that direction, the belt covers the rotating ring. In this respect, it is preferred that, at least at the location where the belt covers the rotating ring, the belt contacts the rotating ring along its longitudinal extension, particularly, face-to-face contact with the rotating ring.

[0042] In the longitudinally extending portion of the band, the band covers a rotating ring in a direction perpendicular to the plane of the circular path, in a direction opposite to that direction, and in a direction facing or away from the center of the circular path. This cover may be mirror-symmetrical with respect to the plane of the circular path. In particular, the band may be mirror-symmetrical with respect to the plane in these portion of the band, or it may be symmetrical along its entire longitudinal extension, possibly except for at least one end of its longitudinal extension.

[0043] Additionally, the belt may have a U-shaped or C-shaped cross-section (perpendicular to the circular path), preferably having a U-shaped or C-shaped cross-section that is at least substantially fixed in these partial regions or along its entire longitudinal direction, with exceptions made for at least one end of its longitudinal extension. In this respect, the open side of the U-shape or C-shape is preferably oriented toward a radial direction relative to the center of the circular path, particularly radially outward.

[0044] According to an advantageous embodiment, the belt is formed as a component separate from the rotating ring, and has fixed and / or flexible dimensions. For this purpose, plastic is particularly suitable as a material for the belt, wherein the plastic can be formed into the shape of the belt, for example, by injection molding.

[0045] According to another advantageous embodiment, the belt is fastened to the rotating ring in a form-fit manner. In this respect, in particular, the form fit exists in all spatial directions, such that there is no direction in which the belt can move relative to the rotating ring, or at least no situation where the belt must deform for this purpose. The form-fit fastener can be integrally provided over at least 80% of the longitudinal extension of the belt. In this respect, the form-fit fastener does not necessarily extend only over a single continuous portion area in the longitudinal extension, but can also be distributed over multiple separate portion areas.

[0046] The belt is preferably fastened to the rotating ring by a latching method, i.e., by a resiliently reversible form-fit. For example, the belt can be attached to the rotating ring by a snap-fit ​​connection. In this respect, the fastening of the belt to the rotating ring requires at least a slight elastic deformation, particularly widening the belt, giving it a corresponding elasticity so that the belt is positioned at the rotating ring, whereby the elasticity at least largely reverses again, such that the belt then engages around the rotating ring in a form-fit manner, i.e., beyond half of its circumference. In particular, this temporary widening and subsequent engagement along the longitudinal direction of the belt can occur anywhere the belt extends circumferentially beyond half the circumference of the rotating ring.

[0047] In addition to the shape fit, the belt may also contact the rotating ring at least partially in a press-fit manner. In this respect, particularly due to the elasticity of the belt, a portion of the belt can preload the rotating ring. The additional press-fit further improves the fastening of the belt to the rotating ring.

[0048] The shape fit of the belt to the rotating ring, particularly the latching advantage, lies in its independence from the angular range of the belt's extension around the rotating ring in the circumferential direction. In particular, this shape fit helps ensure that the belt is reliably positioned on the rotating ring, allowing the rotating ring to be supported by the belt in the rotating ring receiver and guided slidably within the receiver with particularly low interference. In this respect, regardless of the measurement of the belt's circumferential range around the rotating ring, this application also relates to a frame lock for a two-wheeled vehicle, comprising a lock body and a rotating ring assembly. The lock body includes a latch, and the rotating ring assembly includes a rotating ring and a belt. The rotating ring is preferably made of metal, and the belt is preferably made of plastic. The rotating ring extends along a circular path and is adjustable relative to the lock body along this circular path between an open position and a closed position. In the open position, the rotating ring releases the wheels of the two-wheeled vehicle to rotate, and in the closed position, the rotating ring prevents the wheels from rotating. The rotating ring has a blocking structure including an adjacent portion, wherein a latch is adjustable between an unlocked position and a locked position, wherein when the rotating ring is in its closed position and the latch is in its locked position, the latch engages behind the adjacent portion, thereby preventing the rotating ring from being adjusted into the open position, wherein a band is disposed at the rotating ring, extending along a circular path, and configured such that at least a portion of the band extending longitudinally along the rotating ring and at least a portion of the periphery of the rotating ring cover the rotating ring, and wherein the band is fastened to the rotating ring in a form-fitting manner, particularly as a latch. The foregoing and following explanation of the above-described frame lock, particularly its rotating ring device, and the description of different possibilities for the design of the frame lock, also apply to the frame lock of this application to the extent applicable. In particular, not only the embodiments of the above-described frame lock, but also advantageous embodiments of the frame lock of this application can arise from the features of the appended items.

[0049] According to an advantageous embodiment of the frame lock of this application, the end of the rotating ring and the corresponding end of the belt form a pivotal connection having a pin extending along a longitudinal axis perpendicular to the plane of the circular path, wherein the belt is pivotable relative to the rotating ring about the longitudinal axis of the pin. The end of the rotating ring includes one of two longitudinally extending ends of the rotating ring and extends a distance along the circular path from that end. The corresponding end of the belt includes one of two longitudinally extending ends of the belt, i.e., that end corresponds to the end of the rotating ring with respect to its orientation along the circular path, and extends a distance along the circular path from that end. The distances extending from the end of the rotating ring and the corresponding end of the belt may each have a length of several millimeters, for example, up to 15 mm, preferably up to 10 mm, and / or up to 10% of the longitudinal extension of the rotating ring, preferably up to 5%. For the end of the rotating ring and the corresponding end of the belt, this distance is preferably an equal length.

[0050] In particular, the longitudinal axis along which the pin extends may be the axis of symmetry of the pin. The pin may have at least substantially a cylindrical shape, wherein the longitudinal axis is the cylindrical axis of the cylindrical pin. The cross-section of the pin perpendicular to the longitudinal axis is at least partially fixed, preferably along the total length of the pin (i.e., along the longitudinal axis), except for the free end of the pin, which may in particular have a chamfer.

[0051] The longitudinal axis of the pin is preferably oriented in a plane perpendicular to the circular path along which the rotating ring extends. Therefore, when the belt pivots relative to the rotating ring around the longitudinal axis of the pin, the belt can pivot against the rotating ring in at least an approximately radial direction relative to the center of the circular path, so as to be positioned at the rotating ring, particularly fastened in a form-fit manner. Specifically, the belt can be configured to pivot from the inner space of the circular path to the inner side of the arcuate shape of the rotating ring, i.e., the side radially inward (towards the center) relative to the center of the circular path, so as to be positioned on the rotating ring, particularly fastened to the rotating ring in a form-fit manner.

[0052] According to an advantageous embodiment, the form fit between the belt and the rotating ring can be achieved by pivoting the belt around the longitudinal axis of the pin toward the rotating ring. In this respect, the pivoting movement may include the belt's latch at the rotating ring, particularly the latch described further above. Due to this design, the advantageous form fit between the belt and the rotating ring can be achieved in a clearly defined manner.

[0053] Conversely, the belt can also be configured to pivot away from the rotating ring via the longitudinal axis of the pin, thereby releasing the form fit between the belt and the rotating ring. This may facilitate belt replacement in a simple manner.

[0054] According to another advantageous embodiment, a hole is formed in the end of the rotating ring, wherein a pin is formed at the corresponding end of the belt and engages in the hole, preferably perpendicular to the plane of the circular path, specifically through the hole. This design represents a particularly simple type of pivot connection whose components can be easily manufactured, especially in an automated manner, and can be connected to each other. The pin is preferably integrally formed at the corresponding end of the belt and / or connected to the belt in an engaged manner. However, generally, the pin can also be formed as a separate element and can be fixedly connected to the belt.

[0055] As an alternative to this embodiment, the following arrangement may also be made, namely, that, conversely, a pin is formed at the end of the rotating ring, particularly integrally formed at the end of the rotating ring and / or connected to the end of the rotating ring in a coupled manner, and preferably engaged in a hole perpendicular to the circular path plane, particularly through a hole, wherein the hole is formed in the corresponding end of the belt.

[0056] According to an advantageous embodiment, the frame lock further includes a spring for preloading a rotating ring relative to the lock body, wherein the spring is fastened to the pin. The spring is preferably a helical spring, particularly a helical tension spring. Specifically, the rotating ring can be preloaded by the spring in the opening direction.

[0057] To secure the pin, the spring may have an eye formed at one end of the spring, through which the pin can be wound. Specifically, the pin may first engage through the eye of the spring, and then engage or at least engage into the eye. In this respect, the eye is advantageously trapped between the swivel ring and the belt, such that the connection between the swivel ring and the spring is secured in some way by the belt. The eye does not necessarily have to be closed around its entire circumference; it is sufficient if the eye can engage the pin like a hook at least on the main portion of its circumference.

[0058] The rotating ring may be permanently fixed to the lock body, particularly the lock body housing, via a spring, especially solely via a spring. For this purpose, the spring may have another eyelet at its end opposite to the said eyelet, or may be configured in another way to be coupled to the lock body. In its closed position and / or its open position, if the latch engages behind the corresponding adjacent portion formed on the rotating ring, the rotating ring may be additionally secured by the latch and cannot be released from the lock body.

[0059] Therefore, at its end, the rotating ring is not only pivotally connected to the belt, but also to the lock body. Advantageously, no additional structure is required for this purpose; the same structure (pin and hole) can be used for the pivotal connection design as well as for the connection to the lock body.

[0060] According to another advantageous embodiment, the belt has a handle for manually adjusting the rotating ring or a fastening lug for securing such a handle to the belt. The handle or fastening lug may be fastened to the belt or may be integrally formed, particularly integrally formed on the belt, for example, molded on the belt. The handle or fastening lug preferably projects radially outward from the center of the circular path relative to the belt, or projects from the belt in a plane perpendicular to the circular path, and may extend in this direction, for example, through a slot in the housing of the lock body, extending out of the rotating ring receiver. In this way, the handle can be in a position where it can be easily gripped and actuated in both the open and closed positions of the rotating ring device.

[0061] According to another advantageous embodiment, the rotating ring extends longitudinally and has at least one raised portion that engages in a recess in the belt, such that (due to this engagement) a form fit is formed between the belt and the rotating ring relative to the circular path. Alternatively or additionally, the rotating ring may be configured to extend longitudinally and have at least one recess into which the raised portion of the belt engages, such that (due to this engagement) a form fit is formed between the belt and the rotating ring relative to the circular path.

[0062] The recess may be, for example, an opening or cut in the belt or a cut in the rotating ring. The recess in the belt may specifically be formed as a depression extending away from the rotating ring, i.e., extending radially outward relative to the center of the rotating ring's cross-section into the belt. In particular, the recess in the rotating ring may be formed as a depression extending into the rotating ring, i.e., extending radially inward relative to the center of the rotating ring's cross-section.

[0063] The raised portion and / or recess that may be provided on the rotating ring may be part of the blocking structure of the rotating ring. Depending on the shape, arrangement and / or orientation of the respective raised portion or recess, the shape fit effect caused thereby may be limited to one of two possible directions along the circular path.

[0064] In this respect, the form fit along the circular path can in various cases arise, particularly from the engagement of a corresponding raised portion of one component (rotating ring or belt) with a corresponding recess of another component. In other words, if applicable, the belt is fixed in a form fit manner due to the engagement of multiple raised portions and recesses to prevent the belt from moving relative to the rotating ring along the circular path. This results in additional stability to the arrangement of the rotating ring and the belt along the longitudinal extension through their form fit engagement. This (potentially additional) fixation and stability of the rotating ring assembly can be particularly advantageous because, when adjusting the rotating ring assembly, friction acts on the belt, which slides along the inside of the rotating ring receiver; otherwise, this friction would force the belt away from its proper arrangement at the rotating ring.

[0065] According to another advantageous embodiment, the blocking structure includes at least two adjacent portions corresponding to a closed position and an open position of the rotating ring, wherein when the rotating ring is in its closed position or its open position and the latch is in its locked position, the latch engages behind the respective adjacent portion, thereby blocking the rotating ring from being adjusted from the corresponding position. In this aspect, one of the two adjacent portions corresponds to the closed position, i.e., when the rotating ring is in its closed position and the latch is in its locked position, its path relative to the circular path is engaged behind it by the latch, so that it cannot be guided through the latch in the opening direction, and thus prevents the rotating ring from being adjusted from the closed position in the opening direction. In this aspect, the other of the two adjacent portions corresponds to the open position, i.e., when the rotating ring is in its open position and the latch is in its locked position, its path relative to the circular path is engaged behind it by the latch, so that it cannot be guided through the latch in the closing direction, and thus prevents the rotating ring from being adjusted from the open position in the closing direction.

[0066] In this embodiment, the belt preferably extends along a circular path between at least two adjacent portions, i.e., from at least one of the two adjacent portions to the other. In this respect, the belt may also extend along a circular path beyond one or both of the two adjacent portions, but the portion of the belt extending at least longitudinally along the rotating ring covers the rotating ring, with the two adjacent portions surrounding that portion.

[0067] According to an advantageous further development of this embodiment, the blocking structure includes at least two webs projecting from the rotating ring, preferably in the same direction, wherein each of the two webs has one of two adjacent portions, i.e., one web has one adjacent portion and the other web has another adjacent portion. In this respect, the adjacent portions are preferably formed directly on the respective webs, particularly as end faces of the respective webs.

[0068] The direction in which the webs project is preferably perpendicular to the longitudinal extension of the rotating ring, i.e., perpendicular to the path of the circular path. In particular, since the two webs preferably project from the rotating ring in the same direction, the webs can project parallel to each other from the rotating ring. However, the webs can also project from the rotating ring in the same direction, i.e., both webs project from the rotating ring in the same radial direction relative to the center of the circular path. For example, both webs can project radially inward, or both can project radially outward relative to the center of the circular path. The two webs preferably project from the rotating ring in the same axial direction, i.e., in a direction perpendicular to the plane of the circular path.

[0069] In this respect, the entire corresponding web does not need to protrude from the rotating ring; it is sufficient if only part of the web protrudes from the rotating ring. Part of the web may also extend into the rotating ring, particularly transversely to the longitudinal direction of the rotating ring. In particular, the portion of the web protruding from the rotating ring may be a structure that bulges relative to its environment.

[0070] For example, the web may protrude relative to the cross-section of the adjacent portion of the rotating ring, particularly relative to the cross-section of the bar material on which the rotating ring is formed before the blocking structure or at least the web is formed. In this respect, in particular, a web protruding in cross-section means that the web extends beyond the outer contour of the cross-section as viewed along the range of the rotating ring along a circular path.

[0071] Therefore, the portion of the web forming the blocking structure engages with this portion of the blocking structure to prevent the rotating ring from being adjusted from the corresponding position. For this purpose, the web is advantageously formed at the corresponding position of the rotating ring. In other words, the web is configured such that (in particular, arranged such that) when the rotating ring is in its closed position or in its open position and the latch is in its locked position, the latch engages behind the adjacent portion of the corresponding web of the two webs.

[0072] The web, particularly the entire blocking structure, is preferably arranged within the support portion of the rotating ring, i.e., within the longitudinal extension of the rotating ring that remains within the lock body when the rotating ring is adjusted between the closed and open positions, thus advantageously preventing external access.

[0073] In this respect, in particular, a band extending along a circular path between two adjacent portions of the two webs may contact the outer side of the rotating ring from one of the two webs to the other web, the outer side facing the direction of the protrusion. In this respect, the band preferably contacts this outer side directly. However, in general, at least locally, a certain gap may be maintained. Additionally, preferably, the band or at least a portion of the band extends along the outer contour of the rotating ring, which connects the two webs in a manner along a circular path, particularly in a straight line.

[0074] Each of the two webs also has at least two opposing parallel side surfaces extending substantially along a circular path, wherein the adjacent portions of the respective webs are formed by end faces of the webs that connect to the side surfaces of the webs and are oriented at least substantially perpendicular to the circular path.

[0075] In this respect, the two side surfaces are preferably aligned parallel to the direction in which the web protrudes from the rotating ring. In this respect, the web may extend along a circular path. Depending on the direction in which the web protrudes from the rotating ring, the side surfaces may therefore have a path that curves according to the circular path. However, in particular, a relatively short web may also have a straight path tangent to the circular path.

[0076] The direction of the route and the protrusion, transverse to the circular path, at least where the side surface protrudes from the rotating ring, allows the side surfaces to be connected to each other via corresponding edges or edge sides of the web. In this respect, the edge side may also include the end face through which the abutment portion is formed. The edge side is preferably oriented at least substantially perpendicular to the side surface. In particular, this also applies to the end face forming the abutment portion. The orientation of the abutment portion is preferably deviated from the direction perpendicular to the circular path by at most 10°.

[0077] This web, comprising two parallel side surfaces, can be formed relatively easily and inexpensively by cold forming. In a longitudinally extending portion of the rotating ring (or the material forming the rotating ring), where the length corresponds to the length of the web to be formed, the outer region of this portion can be pressed, for example, between a punch and a support from opposing directions, such that the material in this portion is reshaped into the web, which protrudes outward at least partially perpendicular to these directions. Thus, the two side surfaces of the web are oriented perpendicular to the two opposing directions of the pressed portion region.

[0078] In this embodiment, preferably, the belt is further configured to have side surfaces that are at least substantially aligned with one of the side surfaces of one of the two webs and one of the side surfaces of the other web. In this respect, the belt preferably extends at least substantially from one of the two webs to the other. In this respect, the side surfaces of the belt may define the belt in the circumferential direction extending longitudinally around the rotating ring, at least in the region between the two webs.

[0079] Due to the alignment, the three side surfaces (i.e., the two side surfaces of the two webs and the side surface of the belt) can form a continuous path, with the corresponding gaps at the two transitions being excluded. In this respect, in particular, the three side surfaces can be arranged in a plane, or can form a curved path corresponding to a circular path.

[0080] In this respect, in particular, the side surface may face a direction corresponding to the adjustment of the latch from its locked position to its unlocked position. The latch may be preloaded in the opposite direction, i.e., 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 ring, the latch may slide along and abut against the path formed by the side surface for preload, while the rotating ring is adjusted. In this way, during the adjustment of the rotating ring, the latch may be held in its unlocked position by the strap, or at least held in a position that does not obstruct the rotating ring.

[0081] According to another advantageous embodiment, the blocking structure has at least a first adjacent portion facing the closing direction and a second adjacent portion facing the opening direction opposite to the closing direction. The closing direction corresponds to the aforementioned closing direction, wherein the rotating ring is adjusted from its open position to its closed position, and the opening direction corresponds to the aforementioned opening direction, wherein the rotating ring is adjusted from its closed position to its open position. The adjacent portions face their respective directions, specifically meaning that the direction is aligned parallel to and away from the surface normal of the surface of the adjacent portion.

[0082] In particular, the first adjacent portion facing the closing direction may be arranged along a circular path closer to the end of the rotating ring than the second adjacent portion facing the opening direction, forming a pivotal connection with the belt at the end of the rotating ring. The blocking structure may also include two webs projecting from the rotating ring, particularly the aforementioned two webs, wherein one of the two webs has the first adjacent portion and the other of the two webs has the second adjacent portion.

[0083] It can also be configured such that when the rotating ring is in its closed position and the latch is in its locked position, the latch engages behind the first adjacent portion (relative to the opening direction), thereby preventing the rotating ring from being adjusted to the open position, and when the rotating ring is in its open position and the latch is in a partially locked position between its locked position and its unlocked position, the latch engages behind the second adjacent portion (relative to the closing direction), thereby preventing the rotating ring from being adjusted to the closed position, wherein a band is formed in a portion of its longitudinal extension that is adjacent to, and particularly directly adjacent to, the second adjacent portion in the opening direction, such that the band restricts the adjustability of the latch for adjustment between the unlocked position and the partially locked position.

[0084] In other words, in this embodiment, with the rotating ring in the open position, the latch can start from its unlocked position, adjust upwards only in the direction of the locked position, and enter a partially locked position (and return from the partially locked position again), because its adjustability is limited by the belt, wherein the partially locked position can be specifically set approximately at the center between the locked and unlocked positions. Since the latch has already engaged behind the second adjacent portion in the partially locked position (although there may be a small overlap), the rotating ring can still be locked in its open position by the latch. However, when the rotating ring is in the open position, the belt prevents the latch from being adjusted to the locked position.

[0085] Specifically, the band can limit the adjustability of the latch, adjusting between the unlocked position and the partially locked position, because the portion of the band that adjoins the longitudinal extension of the second adjacent portion in the opening direction extends radially outward relative to the center of the circular path than the portion of the band that adjoins the longitudinal extension of the first adjacent portion in the closing direction, such that in the former portion, the band extends into the movement path of the latch between the unlocked and locked positions. When adjusting the latch from the unlocked position, the latch is already adjacent to the band in the partially locked position, and therefore cannot be adjusted to the locked position and enter the locked position. If the second adjacent portion is formed on the web protruding from the rotating ring and, as described above, has two side surfaces, the band can extend in its longitudinally extending portion that adjoins the second adjacent portion in the opening direction, specifically, extending to the plane disposed between the two side surfaces of the web.

[0086] When a frame lock includes a locking device, particularly a lock cylinder, the limitation explained by the adjustability of the latch is particularly advantageous. This latch, housed in the lock body, is actuated by a key associated with the locking device and connected to the latch, for example via a clip, for adjusting the latch such that there is a clear relationship (except for possible gaps) between the corresponding rotational positions and corresponding positions of the key, wherein the key can only be removed from the locking device when it is in the rotational position corresponding to the locked position of the latch. If the clip does not limit the adjustability of the latch, then the latch can therefore be adjusted to its locked position, and the key can then be removed in both the locked and open positions of the rotating ring. However, because the design of the clip limits the adjustability of the latch, it is possible that, with the same functionality in other aspects of the frame lock, the latch can only be adjusted to the locked position in the closed position, not in the open position of the rotating ring, and therefore the key can only be removed when the rotating ring is locked by the latch in its closed position. This corresponds to the so-called key-holding function of frame locks, which is particularly needed in some European countries.

[0087] According to this embodiment, the key-holding function can be advantageously achieved by a belt, particularly a correspondingly formed structure of the belt, and therefore need not be achieved by a specific structure of the rotating ring that might compromise the stability of the rotating ring. Thus, the rotating ring can always be configured in the same way regardless of whether the key-holding function is present, which is particularly advantageous for the manufacture of the rotating ring. The key-holding function can be achieved, as needed, by or without providing a correspondingly formed belt at the rotating ring. Typically, the key-holding function can even be provided or removed subsequently by replacing the belt.

[0088] In this respect, this application also relates to a frame lock system including the frame lock according to this application, the frame lock system therefore including a rotating ring device comprising a rotating ring and a belt, and particularly, the rotating ring device may be constructed in one or more of the above-described manner, wherein the belt is constructed in the above-described manner to achieve a key holding function, and the frame lock system includes, in addition to the belt, another belt selectively disposed at the rotating ring instead of the belt, wherein the other belt is formed such that its longitudinally extending portion corresponds to the portion adjacent to the second adjacent portion in the opening direction, such that the other belt allows adjustability of the latch from the unlocked position to the locked position and into the locked position. Compared to the belt, the other belt therefore does not limit the adjustability of the latch to the partially locked position, such that the latch has the same adjustability in the open position of the rotating ring, particularly, the latch can be adjusted to the locked position and adjusted in the locked position, the latch can also be adjusted from its unlocked position to the locked position in the closed position of the rotating ring so as to engage behind the corresponding adjacent portion, thereby blocking the rotating ring from adjustment.

[0089] Therefore, in such a frame lock system, the resulting frame lock can be equipped with a key retention function or omit the key retention function by selecting the appropriate strap, as needed or by preference. In this respect, the frame lock of the frame lock system can at least initially exist in an unassembled state, such that the preferred form of the strap can be directly arranged at the rotating ring on the assembly of the frame lock.

Implementation Method

[0098] An embodiment of the frame lock 11 according to the present application is shown in FIG1. ​​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, the first branch 17 and the second branch 19 extending out of the corners of the parallelepiped shape.

[0099] A locking device, in the form of a lock cylinder not visible, and a latch 21 (see FIG. 6) connected to the locking device are received in the central portion. The locking device can be actuated in a conventional manner only by means of a key 23 associated with the locking device. In this respect, the latch 21 is connected to the locking device, so that the latch can be adjusted between an unlocked position and a locked position by driving the locking device with the key 23. In this respect, in particular, there is a clear relationship between the corresponding positions of the latch 21 and the corresponding rotational positions of the key 23.

[0100] The frame lock 11 also has a rotating ring 25 that extends along a circular path and is at least partially housed in the housing 15, i.e., housed in a rotating 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 ring 25 is supported relative to the lock body 13 in this respect, allowing it to be adjusted along its longitudinal extension, i.e., along the circular path, between an open and closed position. The rotating ring 25 is made of metal and has a fixed circular cross-section (see FIG. 7), but may also typically have another shape, such as a regular polygon. In this respect, the portion with the fixed cross-section together forms the (largely) principal portion of the longitudinal extension of the rotating ring 25, for example, more than 80%, particularly at least 90%.

[0101] In the closed position, the rotating ring 25 extends from the first branch 17 with its free end 27 and upwards to the second branch 19, thereby connecting the first branch 17, the second branch 19, the lock body 13, and the rotating ring 25 to form a closed loop. In this way, in the corresponding arrangement of the frame lock 11 on the frame of the two-wheeled vehicle (not shown), the rotating ring 25 can engage between the spokes of the wheels of the two-wheeled vehicle, thereby preventing the wheels from rotating.

[0102] Conversely, in the open position, the swivel ring 25 is at least substantially completely contained within the housing 15, or extends only slightly beyond the first branch 17 of the housing 15, particularly only at its free end 27, thereby maintaining free space between the two branches 17, 19, within which the spokes of the wheel can move through the branches 17, 19 of the frame lock 11. Thus, in the open position of the swivel ring, the swivel ring 25 releases the wheels of the two-wheeled vehicle for rotation.

[0103] The portion of the rotating ring 25 arranged outside the housing 15 in the closed position forms a blocking portion 29 of the rotating ring 25, the blocking portion 29 having a through circular cross-section. The blocking portion 29 extends along the circular path within an angular range of approximately 60°. The remaining portion of the rotating ring 25, which is always disposed within the housing 15, forms a support portion 41 of the rotating ring 25.

[0104] If the rotating ring 25 is not prevented from adjustment by the latch 21, the rotating ring 25 can be manually moved from the open position to the closed position via the handle 31, and conversely, returned from the closed position to the open position along the circular path, corresponding to the rotation of the rotating ring 25 about the center M of the circular path. For this purpose, the handle 31 is coupled to the rotating ring 25 and extends perpendicular to the plane of the circular path along which the rotating ring 25 extends, with the handle passing through a groove 33 formed in the first branch 17. The groove 33 has an arcuate path in this respect, wherein the arcuate shape of the groove 33 corresponds to the path of the circular path, and in particular, is coaxial with the circular path, i.e., has the same center M.

[0105] Figure 1 shows the frame lock 11 from a viewing direction perpendicular to the circular path. In Figures 2 and 4, the viewing directions are exactly opposite.

[0106] Figures 2 to 5 show the rotating ring device 47 of the frame lock 11, which includes a rotating ring 25 on one side and a belt 51 and a spring 57 on the other. As can be seen in these figures, the free end 27 of the rotating ring 25 has a tapered bevel. The rotating ring 25 is fastened to the spring 57 at its end opposite to the free end, and is fastened to the lock body 13 via the spring 57. In this respect, this end forms the connecting end 35 of the rotating ring 25.

[0107] At the connecting end 35, the rotating ring 25 flattens on both sides of the plane perpendicular to the circular path, and in particular, has a hole 37 for connecting to the lock body 13, which extends perpendicular to the plane through the circular path of the rotating ring 25.

[0108] To enable the rotating ring 25 to be blocked by the latch 21 and thus prevented from being adjusted between the open and closed positions, the rotating ring 25 has a blocking structure comprising a plurality of webs 39. Each of these webs 39 protrudes from the rotating ring 25 at least partially perpendicular to a plane perpendicular to the circular path. In this respect, in particular, each of the webs 39 protrudes in a circular cross-section as shown in FIG. 7, and specifically the portion of the rotating ring 25 adjacent to the corresponding web 39 along the circular path has this circular cross-section. The webs 39 extend outward beyond the outer contour of this cross-section.

[0109] Each of the webs 39 has two opposing parallel side surfaces 43, which are oriented radially outward or inward relative to the center M of the circular path and thus extend substantially tangentially to the circular path. Additionally, each of the webs 39 has an abutment portion 49 formed by an end face connecting the two side surfaces 43 of the respective web 39, and this end face is at least substantially perpendicular to the route orientation of the circular path (see also FIG. 6).

[0110] The latch 21 and the rotating 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 passes unobstructed as the rotating ring 25 adjusts along a circular path. When the rotating ring 25 is in its closed position or its open position and the latch 21 is in its locked position, the latch 21 thus engages behind the adjacent portion 49 of the corresponding web 39 closest to the direction of adjustment. When the rotating ring 25 adjusts in the corresponding direction, this adjacent portion 49 thus contacts the latch 21, thereby preventing further adjustment of the rotating ring 25 in that direction. In the detailed illustration of FIG. 6, this is shown as an example to illustrate the state in which the rotating ring 25 is in its closed position and the latch 21 is in its locked position.

[0111] The belt 51 of the rotating ring device 47 arranged at the rotating ring 25 extends along a circular path, similar to the rotating ring 25. Therefore, like the rotating ring 25, the belt 51 has at least a substantially arcuate shape. The belt 51, which is formed as an inherently stable member made of plastic, is shaped in this respect and arranged at the rotating ring 25 such that the belt 51 covers the rotating ring 25 along its longitudinally extending portion and its peripheral portion (in the circumferential direction of the route around the circular path). The belt 51 contacts the surface of the rotating ring 25 at the position where it covers the rotating ring 25.

[0112] The belt 51 engages with the hole 37 at the connecting end 35 of the rotating ring 25 by means of a pin 53 formed on the belt 51, and extends from there beyond half of the longitudinal extension of the rotating ring 25, i.e. at least substantially over the entire support portion 41.

[0113] The spring 57 is also secured to the pin 53, which engages in the hole 37. For this purpose, the spring 53 has an eyelet 67 at one end, through which the pin 53 engages before it engages in the hole 37. In this way, the spring 53 is captured between the rotating ring 25 and the belt 51 (see Figures 3 and 5). At the end opposite to the eyelet 67, the spring 53 has another eyelet 69 through which it is connected to the lock body 13.

[0114] The fastening lug 71 is integrally formed on the belt 51 and protrudes from a plane perpendicular to the circular path of the belt 51 (see Figures 3 and 5). The fastening lug 71 is used to fasten the handle 31 to the belt 51. Thus, the handle 31 is connected to the rotating ring 25 via the belt 51, so that the belt 51 acts as a "connector" in this respect. In particular, in this way, the handle 31 or the fastening lug 71 does not need to be directly mounted on the rotating ring 25.

[0115] The belt 51 has a fixed cross-section over most of its longitudinal extension (see FIG7). In particular, the belt 51 has a fixed cross-section between the adjacent portions 49 of the web 39, which correspond to the closed or open position of the rotating ring 25, and the adjacent portions of the web 39 then engage behind when the rotating ring 25 is in its closed or open position and the latch 21 is in its locked position.

[0116] As can be seen in Figure 7, at least in those longitudinally extending portions of the band 51 having the fixed cross-section, the band 51 extends more than halfway around the periphery of the rotating ring 25 in the direction surrounding the outer periphery of the rotating ring 25 (i.e., the route around the circular path). With respect to the center M' of the cross-section of the rotating ring 25 corresponding to the center of the area of ​​this cross-section, the band 51 extends in an angular range of approximately 225° in the circumferential direction around the rotating ring 25. In this respect, the band 51 contacts the outer contour surface of the cross-section of the rotating ring 25, i.e., extends longitudinally along the surface of the rotating ring on its surface. For this purpose, the cross-section of the band 51 has an inner contour complementary to the cross-section of the rotating ring 25, and in the example shown, the band 51 has an arcuate shape due to the circular shape of the cross-section of the rotating ring 25.

[0117] Due to the extension of the belt 51 in the circumferential direction around the rotating ring 25, the belt 51 has a C-shaped cross-section, through which the belt 51 covers the rotating ring 25 in three directions, which are radial with respect to the center M' of the cross-section of the rotating ring 25, and each direction differs from the other by 90° in its orientation. Specifically, the belt 51 covers the rotating ring 25 in the direction perpendicular to the plane of the circular path and in the direction opposite to that direction (left or right in FIG. 7) and in the direction facing the center M of the circular path, wherein the direction facing the center M of the circular path is radially inward (downward in FIG. 7). The cross-section is mirror-symmetric in this respect with respect to the plane of the circular path.

[0118] The cross-section of the band 51 flattens outward relative to the three directions. Thus, the band 51 has three outer sides 59, each of which is planar. The first outer side 59.1 and the second outer side 59.2 are aligned parallel to each other and aligned with the plane of the circular path (i.e., each is positioned on a plane parallel to the plane of the circular path), and define the band 51 in a direction perpendicular to the plane of the circular path. The third outer side 59.3 is oriented perpendicular to the plane of the circular path (i.e., has the shape of a circular band or a cylinder liner), and defines the band 51 in a radial direction relative to the center M of the circular path, i.e., radially inward in the example shown. In this way, the outer sides 59 of the band 51 can slide along the correspondingly oriented in-plane walls of the rotating ring receiver, thereby reliably guiding the entire rotating ring device 47.

[0119] In the circumferential direction surrounding the rotating ring 25, the cross-section of the band 51 is defined by two side surfaces 55, which face radially outward relative to the center M of the circular path. The side surfaces 55 extend along the circular path, in any case from the web 39 corresponding to the closed position of the rotating ring 25 to the web 39 corresponding to the open position of the rotating ring 25, and in this respect are aligned with the two side surfaces 43 of these two webs 39, which face radially outward relative to the center M of the circular path. Thus, the corresponding three side surfaces 49, 55 form a substantially continuous path that the latch 21 can contact and slide along, while the rotating ring 25 adjusts from its open position to its closed position or from its closed position to its open position.

[0120] Due to the engagement of the rotating ring 25 on more than half of its periphery, the belt 51 is fastened to the rotating ring 25 in a form-fitting manner in a radial direction relative to the center M of the circular path. In this respect, the belt 51 has elasticity that allows it to overcome this form fit. Thus, the belt 51 can be fastened to the rotating ring 25 in a latching manner, or it can be released from the rotating ring 25 again.

[0121] The end 61 of the rotating ring 25 forming the hole 37 and the corresponding end 63 of the belt 51 in which the pin 53 is formed form a pivot connection 65. Due to the cooperation between the pin 53 and the hole 37, the pivot connection allows the belt 51 to pivot about the longitudinal axis of the pin 53 relative to the rotating ring 25. The longitudinal axis of the pin 53 corresponds to the cylindrical axis of the pin 53.

[0122] Therefore, in order to arrange the strap 51 at the rotating ring 25 during the assembly of the rotating ring device 47 (or the entire frame lock 11), the strap 51 can first be inserted into the hole 37 of the rotating ring 25 through its pin 53, thereby forming the pivot connection 65, and the strap 51 adopts the position relative to the rotating ring 25 as shown in Figures 4 and 5. Then, starting from this position, the strap 51 can pivot radially from the inside to the outside against the rotating ring 25 relative to the center M of the circular path until it is in the position shown in Figures 2 and 3, in which the strap 51 is in face contact with the rotating ring 25 and engages around it in the portion having the fixed cross section (see Figure 7). Shortly before reaching this position, the C-shaped branch of the strap 51 temporarily widens in this respect, so that the strap 51 snaps onto the rotating ring 25, thereby achieving a form fit in a radial latching manner.

[0123] In the direction along the circular path, the additional shape fit between the belt 51 and the rotating ring 25 is also caused by the belt 51 disposed at the rotating ring 25, the belt 51 extending along the circular path between the webs 39, the webs 39 including adjacent portions 49 corresponding to the closed or open positions of the rotating ring 25. In this respect, the belt 51 extends relative to the plane of the circular path on both sides of the rotating ring 25, in various cases extending from the webs 39 corresponding to the closed position of the outer contour of the rotating ring 25 along the circular path to the webs 39 protruding in the same direction and corresponding to the open position. At the corresponding points along its longitudinal extension, the belt 51 for this purpose has a cutout 45 corresponding to these webs 39, and due to this cutout, the belt 51 extends shorter in the circumferential direction around the rotating ring 25 compared to the longitudinally extending portion of the belt 51 having the fixed cross-section, particularly compared to the portion between the webs 39 corresponding to the closed or open position. Since the webs 39 engage with these cuts 45, the band 51 is held between these webs 39, thus securing it to the rotating ring 25 along a circular path in a form-fit manner. In addition to the webs 39 and cuts 45, further raised portions or recesses may be formed at the rotating ring 25 and the band 51, which, due to their engagement with each other, form a form-fit between the rotating ring 25 and the band 51 relative to the circular path.

[0124] The cut 45 extends not only along the circular path along the length of the corresponding web 39, but also beyond the circular path at the side of the corresponding adjacent portion 49, thereby providing free space where the latch 21 can engage behind the adjacent portion 49. Unlike the embodiment shown in the figure, the cut 45 engaging the web 39 corresponding to the open position can be smaller in the area engaging the adjacent portion 49 than shown in the figure, i.e., the band 51 extends radially outward relative to the center M of the circular path in this area further than shown in the figure, particularly extending approximately to the center between the two side surfaces 43 of the web 39. When the rotating ring 25 is in its open position, the band 51 can thereby restrict the adjustability of the latch 21, adjusting between an unlocked position and a partially locked position, wherein the partially locked position is provided between the unlocked position and the locked position. Thus, a key retention function can be achieved, wherein the key 23 cannot be removed from the lock body 13 in the open position of the rotating ring because the latch 21 cannot be adjusted to the locked position, and therefore the key 23 cannot be adjusted to the corresponding rotational position that allows removal.

[0125] In the frame lock 11, in addition to the strip 51 shown, a strip 51 formed in this optional manner may also be provided to form a frame lock system, wherein one or the other strip 51 may be selectively arranged at the rotating ring 25 to selectively realize the key holding function as needed.
