Abstract
Description
[0001] Ring shackle lock
[0002] The invention relates to a lock with a ring shackle and a locking device, wherein the ring shackle has a first longitudinal end and a second longitudinal end.
[0003] Such locks can be used in a wide variety of applications to protect an object from unauthorized access and / or a space from unauthorized entry. For example, the ring shackle of such a lock can be opened at at least one long end, allowing, for instance, a section of a bicycle frame and a section of a stationary object, such as a bicycle rack, to be inserted into the interior of the ring shackle. The ring shackle can then be closed and locked using the locking mechanism to form a closed loop around the inserted sections, thereby securing the bicycle to the stationary object.Furthermore, the ring shackle of such a lock can, for example, be used to connect a bicycle wheel to a section of the frame, preventing the wheel from rotating and thus preventing unauthorized riding of the bicycle. Similarly, the ring shackle can be threaded through an eyelet of a hasp and then closed and locked to block a door and prevent access to a room enclosed by the door.
[0004] With locks of this type, the primary goal is to make opening, closing, and locking the shackle as simple and convenient as possible, especially given their often mobile use, which frequently involves operating the shackle. For example, when using a lock to secure bicycles, frequent opening and closing of the shackle may be necessary to secure the bicycle at different locations while allowing it to be unlocked for riding in between. Furthermore, particularly with such applications, convenient and space-saving storage and / or transport of the lock is often desirable.
[0005] Therefore, an object of the invention is to provide a lock of the described type which offers a simple and convenient means of selectively opening and locking the ring shackle and which can also be stored or transported compactly. This object is achieved by a lock with the features of claim 1.
[0006] The ring shackle of the lock has a first pivot at its first longitudinal end and is divided at its second longitudinal end, forming a left shackle section and a right shackle section. Furthermore, the ring shackle can be selectively opened or closed by a pivoting movement at the first pivot. The locking mechanism is also formed at the second longitudinal end of the ring shackle and is designed to selectively lock the ring shackle in the closed position.
[0007] By having a first joint at its first longitudinal end, the ring shackle can be divided, in particular by this first joint, into a left shackle section and a right shackle section, whereby the left and right shackle sections can be movable relative to each other at the joint. For example, the two shackle sections can be pivoted relative to each other at the first joint to open the ring shackle, such that the shackle sections at the second longitudinal end are moved apart, creating an opening between each end of the shackle sections. This opening allows, for instance, a section of a bicycle frame and a section of a stationary object to be inserted into an interior of the ring shackle. Therefore, in the open state of the ring shackle, an opening can exist between each end of the shackle sections, through which a section of an object to be secured can be inserted into an interior of the ring shackle.
[0008] To secure an object, after inserting one section into the interior, the shackle sections can be moved towards each other at the first joint by a pivoting motion opposite to the opening motion. This closes the opening between the shackle sections at the second longitudinal end. In the closed position, the ring shackle can therefore form a closed loop that completely encloses and / or surrounds the interior of the ring shackle. Subsequently, or during the pivoting motion to close the ring shackle, the shackle sections can also be locked together to prevent unauthorized opening of the ring shackle.
[0009] The lock can thus be operated, in a sense, like a pair of pliers, to open and close the shackle. The shackle sections can be moved apart (opening) or together (closing) by pivoting them at the first joint located at the first longitudinal end. This allows for simple and intuitive operation of the lock. Furthermore, the locking mechanism, by being integrated directly into the second longitudinal end of the shackle, can be integrated into the shackle itself, resulting in a compact and elegant lock design. For example, this eliminates the need to insert the shackle sections into a separate lock housing during use.Rather, the bracket sections can be directly moved into a position by the pivoting movement at the first joint in which the bracket sections can be locked together.
[0010] For example, the locking device can have a locking mechanism at one end section of a shackle section of the two shackle sections (left shackle section or right shackle section) and a locking section at one end section of the other shackle section, which can optionally be locked by means of the locking mechanism on one shackle section when the ring shackle is in the closed state.
[0011] Furthermore, it may be provided, for example, that the left and right shackle sections can be locked together solely and / or exclusively by performing the pivoting movement at the first joint to close the ring shackle, so that securely locking the lock may only require moving the ring shackle into the closed position and / or forming a closed loop using the ring shackle. The locking device may therefore, in some embodiments, provide an automatic function for locking the shackle sections, as explained in more detail below. However, it may also be provided that the ring shackle must first be moved into the closed position in order to then lock it deliberately and intentionally in a further step, for example, by operating a lock cylinder with a key.
[0012] In principle, the locking device and / or the aforementioned locking mechanism for locking the shackle sections together can, for example, include a locking cylinder that can be operated by a mechanical key, by means of which a bolt can be driven. Furthermore, it can also be provided, for example, that the locking device includes an electronic cylinder for driving such a bolt, whereby such an electronic cylinder can, in particular, be set in rotation by an electric motor.Furthermore, the lock can, for example, be designed as a combination lock and have several rotatable code rings, whereby the interlocked shackle sections can be released from each other and the shackle opened by setting a code on the code rings, whereas the shackle sections can be secured against separation from each other when no code is set. Therefore, when no code is set, a bolt of the locking mechanism can, for example, be blocked from moving into an unlocked position, while when a code is set, the bolt can be released to move into the unlocked position. Such a function of combination locks is generally known to those skilled in the art, so it need not be discussed in detail here.
[0013] The ring shackle can be made of steel, for example, round or flat steel. It can also be hardened. However, the lock may have a covering, particularly made of plastic, that surrounds the ring shackle and / or its shackle sections.
[0014] Further embodiments can be found in the dependent claims, the description and the figures.
[0015] In some embodiments, the locking device may be designed to automatically lock the left bracket section and the right bracket section together when the ring bracket is closed by the pivoting movement at the first joint.
[0016] For this purpose, the locking device can, for example, have a bolt pre-tensioned towards a locking position, which is designed to be contacted by one of the shackle sections at the first joint during the pivoting movement and thus displaced from the locking position. However, the bolt can be designed to return to the locking position after the pivoting movement has ended due to the pre-tension, thereby locking the shackle sections together. Therefore, such a pre-tensioned bolt can provide an automatic function for the lock, enabling it to lock automatically and immediately as a result of the shackle closing by performing the pivoting movement at the first joint, without requiring any separate actuation of the locking device.While such a pre-tensioned bolt can thus be forced out of the locking position by the pivoting movement to close the ring yoke, the bolt in the locking position can block the yoke sections relative to each other against a pivoting movement at the first joint to open the ring yoke after the ring yoke has been closed. For example, the bolt and / or the yoke section lockable by the bolt, and in particular a closing section of the yoke section, can have a chamfer by which the bolt can be forced out of the locking position against the pre-tension when the ring yoke is closed.Furthermore, the bolt and the lockable shackle section, in particular the locking section, can, for example, have stop surfaces oriented perpendicular to a direction of the pivoting movement for opening the ring shackle, which lie against each other when the ring shackle is locked and can thereby prevent the shackle sections from separating from each other.
[0017] However, in order to open the ring bolt, the bolt can be connected to an actuator, for example a locking cylinder or an electric drive, so that authorized persons can, by actuating the actuator and, for example, turning a locking cylinder with an assigned key, selectively force the bolt into an unlocking position against the preload, thereby releasing the bolt sections from each other.
[0018] In some embodiments, the aforementioned bolt can be translationally movable between the locked and unlocked positions and, in particular, can be biased into the locked position by a spring. In other embodiments, however, the bolt can be designed as a rotary bolt and be rotatable between the unlocked and locked positions. In such embodiments, the bolt can therefore be biased into the locked position, in particular, by a torsion spring.
[0019] In some embodiments, the locking device can be purely mechanical. In other embodiments, however, the locking device can be electromechanical.
[0020] For example, a purely mechanical locking device can have a locking cylinder that can be operated by an associated key in order to lock the two shackle sections together. A rotary bolt can be coupled to such a locking cylinder of a purely mechanical locking device in a rotationally effective manner, so that a rotation of the locking cylinder can be transferred to the rotary bolt to drive the rotary bolt from a locked position to an unlocked position – and, if necessary, vice versa.Alternatively, a purely mechanical locking device can, for example, have a number wheel with several rotatable code rings on which a key secret can be set or adjusted, wherein the lever sections can be locked to each other by a bolt when the ring lever is in the closed state and the key secret is not set, but can be released from each other by setting the key secret.
[0021] An electromechanical locking device, on the other hand, can have an electric drive for operating a bolt, in order to selectively lock the shackle sections together in the closed state of the ring shackle or to release them from each other and open the ring shackle. For this purpose, an electromechanical locking device (or its electromechanical locking mechanism) can, in particular, have an electric motor for generating drive power to operate the bolt and an electrical energy source for providing the electrical energy required by the electric motor.
[0022] Furthermore, an electromechanical locking device may, for example, include a radio receiver to receive commands for selectively releasing and / or locking the closed ring bar via a radio connection, such as a cellular connection, Bluetooth connection, NFC (Near Field Communication) connection, RFID (Radio Frequency Identification) connection, and / or WLAN / WiFi connection. Additionally, a control unit (e.g., a microprocessor) may be provided to control the electric drive according to the received commands, which may be sent from a smartphone, for example.As an alternative to transmitting commands via a radio link, an electromechanical locking device can, for example, also have sensors for capturing biometric features, such as a fingerprint sensor, in order to transmit and execute a command to release the ring clasp, for example, after verifying a respective biometric parameter, such as a fingerprint.
[0023] In some embodiments, the ring bracket can have a second hinge on both the left and right bracket sections, dividing each section into a front and a rear bracket segment. Furthermore, in such embodiments, the ring bracket can be selectively folded into a storage position by means of a pivoting movement at the second hinges. Consequently, in such embodiments, the ring bracket can be opened or closed by a pivoting movement at the first hinge, i.e., moved between an open and a closed state.In this configuration, the ring clasp can be open at its second longitudinal end in the open state, particularly to allow a section of an object to be secured to be inserted into an interior space of the ring clasp. Conversely, as a result of the pivoting movement at the first joint and the movement of the ring clasp into the closed state, the ring clasp can form a closed loop that encloses the inserted section of the object to be secured. Since the clasp sections only need to perform a pivoting movement at the first joint to open and close the ring clasp, they can be guided in a plane of extension of the ring clasp during this pivoting movement. Thus, in the closed state, after the pivoting movement at the first joint, the ring clasp can extend as a closed loop in this plane of extension.
[0024] However, in some embodiments, the two shackle sections can be divided into respective front shackle segments and rear shackle segments, which are connected to each other via a respective second joint. This allows the ring shackle to allow further pivoting movements at the second joints of the shackle sections in addition to the pivoting movement at the first joint, which increases the flexibility of handling and, in particular, allows the lock to be moved into a compact storage position.
[0025] For example, by using second joints whose joint axes are aligned parallel to the joint axis of the first joint, the shape of the ring loop can be changed within the aforementioned plane of extension, allowing for the formation of a relatively narrower or wider loop. Conversely, joint axes of the second joints aligned perpendicular to the joint axis of the first joint can allow the loop segments to pivot out of the aforementioned plane of extension, thus enabling flexible adjustment of the ring loop during use.
[0026] In particular, the shackle and / or the lock can optionally be folded into a storage position by means of the pivoting movement at the second joints, in order to store and / or transport the lock in a compact arrangement. Because the lock can be folded into the storage position, its extension in this position can be fundamentally reduced compared to its extension when not in the storage position. Furthermore, for example, the distance between the two longitudinal ends of the shackle in the storage position can be smaller than in a working position of the lock or shackle, in which the shackle segments are not deflected relative to each other at the second joints.
[0027] In general, a position of use of the ring bracket within the scope of the present disclosure can denote a position of the ring bracket in which the bracket segments of a respective bracket section are not pivoted relative to each other at the second joints.
[0028] In particular, the ring clasp can also extend in the aforementioned plane of extension in the storage position, in which the ring clasp is in the closed state when it forms a closed loop, without the clasp segments being deflected or pivoted relative to each other at the second joints. For example, if the joint axes of the second joints are oriented perpendicular to the joint axis of the first joint, it can be provided that the clasp segments are first folded out of the plane of extension to fold the ring clasp into the storage position, and then folded back into the plane of extension. In particular, folding the ring clasp into the storage position can therefore involve a pivoting movement of the clasp segments of a respective clasp section by 180 degrees relative to each other at the second joints.In contrast, if the joint axes of the second joints are aligned parallel to the joint axis of the first joint, it may be provided that folding into the storage position takes place within the extension plane of the ring bracket, whereby, for example, the front bracket segments can be pivoted into the rear bracket segments or pivoted outwards against the rear bracket segments.
[0029] In some embodiments, the ring bracket can be folded by means of a pivoting movement at the second joints in such a way that the rear bracket segment and the front bracket segment of the respective bracket section lie next to each other. Thus, the front bracket segment of a given bracket section can, in a sense, be folded back into its storage position relative to the rear bracket segment during folding, in order to lie next to the rear bracket segment and thereby reduce the extension of the ring bracket, while still achieving an arrangement of the ring bracket within a single plane of extension.
[0030] In some embodiments, the rear shackle segments of the shackle sections can, in the storage position, run along the respective front shackle segment of the associated shackle section and extend in a storage plane defined by the extension of the front shackle segments. In particular, in such embodiments, it can be provided that, starting from a working position of the ring shackle in which the shackle segments are not pivoted relative to each other at the second pivot points and the ring shackle can extend as a whole in a single plane, the rear shackle segments can be folded relative to the front shackle segments around the second pivot axes in the direction of the front shackle segments in order to be folded into a storage plane defined by the front shackle segments and thereby transfer the lock or ring shackle into a compact storage position.With the front shackle segments remaining stationary during this folding process, the storage plane can correspond to the extension plane. Furthermore, by allowing the front shackle segments to extend along the rear shackle segments in the storage position, the lock's overall extension in this position can be minimized, as the rear shackle segments can directly connect to an outer or inner surface of the front shackle segments. In particular, the shape of the lock in the storage position can therefore be essentially determined by the shape of the front shackle segments.
[0031] In general, the lock can be folded into the storage position by the pivoting movement of the rear shackle segments relative to the front shackle segments, so that to move the ring shackle into the storage position the rear shackle segments, the front shackle segments and / or both the rear shackle segments and the front shackle segments can be moved.
[0032] Furthermore, in some embodiments, the first longitudinal end and the second longitudinal end of the ring bracket can be arranged directly adjacent to each other in the storage position.
[0033] In a working position of the ring bracket, in which the bracket segments are not pivoted relative to each other at the second joints, the first longitudinal end and the second longitudinal end can be arranged in opposite directions and separated from each other by an interior space enclosed by the ring bracket. In the working position, the interior space of the ring bracket can therefore separate the longitudinal ends, which are thus not adjacent to each other in the working position, but rather form opposite ends of the loop created by the ring bracket in its closed state. However, due to the pivoting movement at the second joints, the front bracket segments can be folded relative to the rear bracket segments in such a way that the second longitudinal end comes into closer proximity to the first longitudinal end.Therefore, in the storage position, the two longitudinal ends can lie directly against each other or be separated only by a gap between the respective front and rear bracket segments of a bracket section. In a sense, the two longitudinal ends can thus be arranged directly one behind the other in the storage position.
[0034] In some embodiments, the rear bracket segments can be rotated 360 degrees around the second joints relative to the front bracket segments.
[0035] In some embodiments, the front shackle segments can be pivoted relative to the rear shackle segments about the second joints when the shackle is in the closed position. Such a design of the ring shackle can, in particular, make it possible to pivot the ring shackle out of a plane of extension, even when closed, instead of forming a flat loop, and / or to change the shape of the loop within the plane of extension, thereby achieving greater flexibility in the use of the lock.
[0036] In some embodiments, the pivot axes of the second joints can coincide. In particular, the pivot axes of the second joint axes can fold together in such embodiments when the ring shackle is in the operating position and in the closed state. In such embodiments, the front shackle segments can thus pivot about a common pivot axis relative to the rear shackle segments, so that the shackle segments can be moved and, in particular, pivoted in the same way to move the lock into the storage position. In particular, this allows for a symmetrical and controlled operation of the ring shackle.
[0037] In some embodiments, the joint axes of the second joints can be aligned perpendicular to the joint axis of the first joint.
[0038] In particular, in such embodiments, the joint axes of the second joints can intersect the joint axis of the first joint without, however, cutting through it. Therefore, in such embodiments, the joint axes of the second joints can be arranged perpendicular to and spaced apart from the joint axis of the first joint.
[0039] For example, in such embodiments, the ring bracket can be selectively opened or closed by a pincer-like movement and a pivoting of the bracket sections about the pivot axis of the first joint, whereby such a movement can occur, in particular, within a plane of extension of the ring bracket to which the pivot axis of the first joint is consequently perpendicular. Conversely, the ring bracket can be folded into the storage position by a pivoting movement about a pivot axis perpendicular to it—the pivot axis of the second joints—so that, in the course of folding into the storage position, the rear bracket segments can be pivoted out of the aforementioned plane of extension relative to the front bracket segments.However, in the storage position, the shackle segments can again be folded into the extension plane, so that a flat and compact arrangement of the ring shackle or lock can result once more in the storage position. In particular, the ring shackle can therefore be folded into the storage position, starting from a closed loop formed in an extension plane, by a pivoting movement of the rear shackle segments relative to the front shackle segments by 180 degrees around a pivot axis of the second joints running in the extension plane.
[0040] Alternatively, in some embodiments, the joint axes of the second joints may be aligned parallel to the joint axis of the first joint. In particular, the joint axes of the second joints may run parallel to the joint axis of the first joint without intersecting it. In such embodiments, the front bracket sections may be pivotable relative to the rear bracket sections in a plane to move the ring bracket into the storage position. This plane is also used to selectively open or close the ring bracket at the first joint.
[0041] Such a pivoting movement can also enable the ring clasp to be folded into a compact storage position, for which the front clasp segments, especially when viewed relative to the rear clasp segments, can be folded back by a pivoting movement at the second joints, so that, for example, the respective outer sides of the front clasp segments and rear clasp segments of a respective clasp section can come into contact with each other when the ring clasp is in the storage position.In some embodiments, the ring bracket can be pivoted into a substantially oval or circular shape by means of the pivoting movement at the first joint, which spans a plane of extension in the closed state of the ring bracket, not folded into the storage position, wherein the joint axis of the first joint can run perpendicular to the plane of extension and wherein the joint axes of the second joints can run within the plane of extension.
[0042] In particular, the ring clasp can be brought into a closed state and into the form of a closed loop by means of a pivoting movement at the first joint, whereby this loop can, in particular, have an oval or circular shape. However, it is also possible, for example, for the ring clasp to be brought into a rectangular, triangular, or rhombus shape by means of a pivoting movement at the first joint and its being brought into the closed state.
[0043] As previously explained, due to the perpendicular orientation of the first joint's axis to the plane of extension, the bracket segments can be moved, particularly within the plane of extension, by the pivoting movement at the first joint. Conversely, moving the bracket segments to fold the ring bracket into its storage position can initially move the bracket segments out of the plane of extension. However, in the storage position of the ring bracket, the bracket segments may again be arranged in the plane of extension or the aforementioned storage plane. Therefore, the ring bracket can also extend within the plane of extension in its storage position, although, due to the folding into this position, the ring bracket may have a smaller overall extension within the plane of extension compared to its oval or round shape (or, more generally, its respective loop shape).
[0044] In some embodiments, each of the bracket segments can be curved. In particular, each of the bracket segments can be substantially J-shaped or C-shaped. This can make it possible, in particular, to arrange the bracket segments side by side in the storage position, since the bracket segments can have a corresponding shape. Furthermore, substantially J-shaped bracket segments can form a total of substantially C-shaped bracket sections, which, in the closed state, can form respective halves of a closed loop with an oval, circular, or substantially rectangular shape. In general, in some embodiments, the respective end sections of the front bracket segments, which lie against each other at the second longitudinal end when the ring bracket is closed, can also lie against each other in the storage position.Alternatively or additionally, in some designs the ring bracket can also be locked and / or locked in the storage position.
[0045] In some embodiments, the ring clasp can be folded into the storage position when closed. In such embodiments, it may therefore be necessary to first move the ring clasp into the closed position and then fold it into the storage position. In this respect, the clasp sections of the ring clasp can also be connected to each other in the storage position, so that the ring clasp can be stored stably and, for example, transported.
[0046] The front bracket segments can essentially form an I-shape when the ring bracket is closed, and the rear bracket segments can also essentially form an I-shape when the ring bracket is closed. Furthermore, the I-shape of the rear bracket segments can pivot into the U-shape of the front bracket segments by means of the pivoting movement at the second joints.
[0047] In particular, the respective U-shapes of the rear and front bracket segments can be mirror images of each other in the closed and operational state of the ring bracket, so that the respective legs of the U-shapes face each other to form a closed loop using the ring bracket. In the storage position, however, the respective U-shapes can be identically oriented and, in particular, lie within each other to create a compact arrangement of the ring bracket. Specifically, the U-shape of the rear bracket sections can be folded into the U-shape of the front bracket sections in the storage position, so that the respective outer sides of the rear bracket segments extend along the respective inner sides of the front bracket segments.Alternatively, a reverse arrangement can also be provided, in which a U-shape of the front temple segments can be pivoted into a U-shape of the rear temple segments, so that respective outer sides of the front temple segments can extend along respective inner sides of the rear temple segments in the storage position.
[0048] In particular, the ring clasp can therefore have a U-shape in some embodiments when stored. Furthermore, in such embodiments, the ring clasp can form a closed loop, especially when closed and in the operating position.
[0049] In the context of this revelation, a U-shape is generally to be understood broadly as a shape in which two legs are connected by a connecting section or at a connecting point and extend from the connecting section or point in the same direction. In this respect, for example, a half-rectangular shape or a V-shape can also be understood as U-shaped within the meaning of this revelation.
[0050] In some embodiments, the locking device may have a locking section on one yoke section of an insertion opening and a locking section on the other yoke section, which can be inserted into the insertion opening by pivoting at the first joint along an insertion direction. Furthermore, the locking device may have a rotary latch on one yoke section, which is rotatable about a pivot axis between an unlocked position and a locked position, and which may be biased into the locked position. Additionally, the rotary latch can be forced into the unlocked position against the bias by a cam formed on the locking section when the locking section is inserted, and may be designed to rotate back into the locked position as a result of the locking section being fully inserted into the insertion opening.
[0051] The axis of rotation of the rotary bolt can generally be aligned perpendicular to the insertion direction of the locking section of the aforementioned other bolt section.
[0052] In particular, the rotary bolt can be designed to return to the locked position due to preload as soon as the locking section is fully inserted into the insertion opening. The rotary bolt can therefore enable an automatic function of the lock, as the two shackle sections can be locked together immediately upon insertion of the locking section into the insertion opening. For this purpose, the rotary bolt can be preloaded into the locked position, in particular by means of a torsion spring, so that the bolt must be rotated against the tension of the torsion spring in order to reach the unlocked position and release the locking section from the insertion opening.In comparison to translationally movable bolts that are pre-tensioned into a locking position, such a rotary bolt can therefore offer particular protection against break-in attempts using the so-called hammer blow method, in which a blow is applied to a lock housing to briefly push back a translationally pre-tensioned bolt against the pre-tension and at the same time pull on a locking section so that the locking section can be released from the lock housing.
[0053] In particular, the rotary bolt can be rotated from the locked position to the unlocked position by a force transmitted tangentially to the rotary bolt from the cam to the rotary bolt during insertion of the locking section. While a subsequent pull on the shackle section containing the locking section can, in principle, transmit a tangential force to the rotary bolt opposite to the tangential force transmitted during insertion, any resulting rotation of the rotary bolt can be blocked by the locking mechanism, and the inserted locking bar can be locked against such release from the insertion opening. Therefore, to move the rotary bolt to the unlocked position and remove the locking section when it is inserted and locked, proper operation of the locking mechanism may be necessary.
[0054] For example, the rotary bolt can have a removal recess which, in the unlocked position of the rotary bolt, can be aligned with a path described by the locking bar or its cam when removed from the insertion opening, so that, in particular, the cam can be guided through such a removal recess when the rotary bolt is in the unlocked position. In the locked position, however, the removal recess can be rotated in such a way that the cam cannot be guided through the removal recess, but instead abuts a limit of the rotary bolt when a force directed out of the insertion opening is exerted on the locking section.
[0055] In some embodiments, the locking device may also include a locking cylinder or an electric drive on one of the shackle sections, which may be designed to drive an eccentric to rotate. Furthermore, with the locking section inserted into the insertion opening, the rotary bolt can be moved into the unlocked position by rotating the eccentric.
[0056] In particular, a lock cylinder can be operated and rotated by means of an associated mechanical key, thereby also enabling the eccentric, which can be rotatably coupled to a part of the lock cylinder, to rotate. Such a lock cylinder can, in particular, have a cylinder core rotatably mounted in a cylinder housing and several tumblers which can be sorted by the associated key, but which, when the key is not inserted, block rotation of the cylinder core relative to the cylinder housing.
[0057] An electric drive can, in particular, include an electric motor to generate a rotary motion in order to drive an eccentric to the rotation described.
[0058] In particular, the eccentric can be designed to contact the rotary bolt in the locked position and block it against rotation, for example, due to a forceful pulling action on the locking section. However, due to such contact, the eccentric can engage the rotary bolt when rotated by the locking cylinder or the electric drive, thus turning the rotary bolt into the unlocked position and releasing the inserted locking section for removal from the insertion opening. Specifically, the eccentric can therefore rest against a stop surface of the rotary bolt in the locked position to prevent rotation of the rotary bolt by pulling on the locking section against the insertion direction and, at the same time, to selectively drive the rotary bolt into the unlocked position.
[0059] According to one embodiment, the rotary bolt can be rotatable about an axis of rotation oriented perpendicular to the insertion direction of the locking section, wherein the locking cylinder or electric drive is oriented parallel to the insertion direction and the eccentric can be driven to rotate about an axis of rotation oriented parallel to the insertion direction. If the axis of rotation of the eccentric and the locking cylinder or the electric drive are oriented parallel to the insertion direction, the axis of rotation of the eccentric can correspond to, or be aligned parallel to, the axis of rotation of a cylinder core of the locking cylinder or a motor shaft of an electric motor of the electric drive.
[0060] In some embodiments, the axis of rotation of the eccentric and / or the cylinder core and / or the electric motor can be arranged perpendicular to the axis of rotation of the rotary bolt, particularly if the axis of rotation of the rotary bolt is aligned perpendicular to the insertion direction of the locking section. This allows for a more compact design of the locking device, as not all components of the locking device are aligned along the insertion direction, but rather the perpendicular orientation of the rotary bolt saves space in this direction.
[0061] In general, the aforementioned locking mechanism of the locking device can be arranged on one shackle section in order to selectively lock the locking section of the locking device located on the other shackle section. The locking mechanism can therefore comprise one or more of the components mentioned above as being arranged on one shackle section.
[0062] In some embodiments, the lock can have a lock body and a protective housing at the second longitudinal end of the ring shackle, which surround at least part of the locking device and to which one of the shackle sections is fixed. The protective housing can be hooked onto the lock body at one attachment point – in particular at one end – and attached to the lock body at another attachment point – in particular at another end – of the lock body, with one shackle section being trapped between the lock body and the protective housing.
[0063] In particular, components of the locking mechanism can be arranged within the lock body, and the protective housing can serve to close any openings in the lock body required to accommodate these components, thereby securing them against unauthorized access. However, the protective housing may, for example, have the aforementioned insertion opening for inserting a locking section, or the insertion opening may remain open on the lock body. It is not necessary for the lock body and the protective housing to completely enclose the locking mechanism.
[0064] By allowing the protective housing to be hooked onto one mounting point of the lock body, it only needs to be attached to the other mounting point, thus enabling quick and easy installation. Furthermore, the protective housing can be made of a hardened material to provide reliable protection against forced entry and / or sawing.
[0065] Furthermore, attaching the protective housing to the lock body can also enable the connection of the aforementioned shackle section to the components of the locking device provided thereon, by means of which the shackle section can be captured, in particular directly between the lock body and the protective housing. Specifically, the shackle section can be captured between the lock body and the protective housing by positive locking. In some embodiments, the aforementioned rotary bolt, as well as the aforementioned locking cylinder or the aforementioned electric drive, can be held in the lock body and / or the protective housing can at least partially surround the rotary bolt.
[0066] In some embodiments, the lock body, the protective housing, and one shackle section can be held together by a single fastening means. For example, the protective housing can be fastened to the lock body at the end where it is attached by a rivet passing through both the protective housing and the lock body, with one shackle section being trapped between the rivet and the protective housing in such a way that it cannot slip out of the lock body. For example, retaining projections can also be provided on the protective housing to engage in openings formed on the shackle section and prevent the shackle section from slipping out of the gap formed by the rivet and the protective housing.Furthermore, a sufficiently small distance between the rivet and the protective housing can prevent the shackle section from detaching from the retaining projections, in order to securely connect the shackle section to the lock body and the protective housing.
[0067] In some embodiments, the locking section can be covered by a sleeve that is pre-tensioned in the direction of one of the shackle sections. Such a sleeve can, in particular, be pushed back against the pre-tension when the ring shackle is closed, so that the locking section can emerge from the sleeve and be inserted into the insertion opening. Conversely, when the ring shackle is open, the sleeve can cover the locking section to protect it, for example, from damage or contamination.
[0068] The invention is explained below by way of example using a specific embodiment with reference to the drawings.
[0069] They show:
[0070] Figs. 1A to 1C are respective perspective views of a lock with a ring shackle in an open state, in a closed state in which the ring shackle forms a closed loop, and in a state folded into a storage position; Figs. 2A and 2B show a further view of the lock with the ring shackle cover removed, as well as a detail view of a second longitudinal end of the ring shackle, on which a locking device is formed;
[0071] Figs. 3A and 3B are respective exploded views of components of the locking device arranged on a front bracket segment of a left bracket section of the ring bracket;
[0072] Figs. 4A to 4C show respective illustrations of a rotary latch rotatable between a locking position and an unlocking position with the rotary latch in the locking position, with the rotary latch in the locking position and the locking bolt section, and with the rotary latch in the unlocking position; and
[0073] Fig. 5 shows an exploded view of components of the locking device arranged on a front bracket segment of a right bracket section of the ring bracket.
[0074] Fig. 1A shows a lock 11 with a ring shackle 13, which in Fig. 1A is in an open state O. The ring shackle 13 extends between a first longitudinal end 15 and a second longitudinal end 17 and has a first joint 21 at the first longitudinal end 15, so that the ring shackle 13 is divided into two shackle sections 25 and 27 which can pivot relative to each other at the first joint 21, forming a left shackle section 25 and a right shackle section 27. Furthermore, in a working position H, the ring shackle 13 extends within a plane of extension E, with a pivot axis G1 of the first joint 21 being oriented perpendicular to the plane of extension E.
[0075] As can be seen from the combined view of Figs. 1A and 1B, the design of the ring bracket 13 with the first joint 21 allows the ring bracket 13 to be pivoted, like a pair of pliers, by a pivoting movement P1 of the bracket sections 25 and 27 at the first joint 21 from the open state O shown in Fig. 1A to a closed state C shown in Fig. 1B (or vice versa). Fig. 1A shows that in the open state O, the bracket sections 25 and 27 are separated from each other at the second longitudinal end 17 of the ring bracket 13, so that an opening 29 exists at the second longitudinal end 17 between the respective ends of the bracket sections 25 and 27, and a frame section of a bicycle and a section of a stationary object, for example a bicycle stand, can be inserted into an interior 19 of the ring bracket 13.By means of the pivoting movement P1 and the movement of the ring clasp 13 into the closed state C, the ring clasp 13 forms a closed loop S extending in the plane E, so that in the aforementioned example the frame section of the bicycle and the stationary object can be connected to each other by the closed ring clasp 13, and removal of the bicycle from the stationary object can be prevented. Furthermore, Fig. 1B shows that the ring clasp 13 has an oval shape 43 in the closed state and in the operating position H, and thus forms an oval closed loop S, which ultimately spans the plane E.
[0076] Furthermore, Figures 1A and 1B illustrate that a locking device 23 is formed at the second longitudinal end 17, at which the ring yoke 13 can be selectively opened or closed. This locking device has a locking section 47 covered by a sleeve 87 on the right yoke section 27 and a locking mechanism 18 on the left yoke section 25. As explained in more detail below, the locking section 47, and thus the right yoke section 27, can be selectively locked to the left yoke section 25 by means of a rotary bolt 49, which can be operated by a key 61, in order to secure the ring yoke 13 in the closed state C (see also Figures 3A to 40).
[0077] As explained in more detail below, the locking device 23 is also designed to automatically lock the left shackle section 25 and the right shackle section 27 together when the ring shackle 13 is closed by the pivoting movement P1 at the first joint 21 and moved from the open state O to the closed state C. In this respect, the lock 11 allows for easy operation to open, close, and lock the ring shackle 13, as the shackle sections 25 and 27 can be selectively moved apart at the second longitudinal end 17 to open the lock 11, or brought together to move the lock 11 to the closed state C and lock the shackle sections 25 and 27 directly to each other.
[0078] However, in order to also enable compact storage and convenient transport of the lock 11, a second joint 31 is formed on the left shackle section 25 and a second joint 37 on the right shackle section 27, so that the left shackle section 25 is divided into a rear shackle segment 35 and a front shackle segment 33, and the right shackle section 27 into a rear shackle segment 41 and a front shackle segment 39. As can be seen particularly in Fig. 1B, the joint axes G2 of the second joints 31 and 37 are aligned within the plane of extension E of the ring shackle 13 when the ring shackle 13 is in the closed state C and in the operating position H, and coincide in this state of the ring shackle 13.
[0079] The second joints 31 and 37 therefore make it possible in particular to move the ring bracket 13 from the position shown in Fig. 1 B by a pivoting movement P2 at the second joints 31 and 37 into a storage position A illustrated in Fig. 1C, in which the rear bracket segments 35 and 41 run along the respective front bracket segments 33 and 39 of the associated bracket section 25 or 27. Since the second pivot axes G2 are aligned within the extension plane E, the rear shackle segments 35 and 41 can, in a sense, initially be folded out of the extension plane E of the ring shackle 13 relative to the front shackle segments 33 and 39, whereby the rear shackle segments 35 and 41, however, return to the extension plane E in the storage position A, so that the lock 11 also forms a flat arrangement in the storage position A and extends in the extension plane E.Furthermore, the rear bracket segments 35 and 41 are thus in storage position A in a storage plane F defined by the front bracket segments 33 and 39, which corresponds to the extension plane E in the case of the front bracket segments 33 and 39 remaining unmoved during the pivoting movement P2.
[0080] In particular, the folding of the ring clasp 13 into storage position A can also take place in the closed state C of the ring clasp 13, so that the ring clasp 13 can, for example, first be brought into the closed state C shown in Fig. 1B in order to then be folded into storage position A. In addition, the two clasp sections 25 and 27 can also be locked together and / or locked together, particularly in storage position A.
[0081] Furthermore, it is particularly evident from Figures 1B and 1C that the respective bracket segments 33, 35, 39 and 41 of the bracket sections 25 and 27 are all essentially J-shaped. This allows the bracket sections 25 and 27 to be designed as a whole in a C-shape, in order to form the closed loop S with oval shape 43 illustrated in Figure 1B when the ring bracket 13 is closed.Furthermore, due to the shape of the bracket segments 33, 35, 39 and 41, folding the ring bracket 13 into storage position A allows the respective rear bracket segments 35 and 41 to extend along the associated front bracket segments 33 and 39, and the respective rear bracket segments 35 and 41 to lie next to the associated front bracket segments 33 and 39 in storage position A, whereby the bracket sections 25 and 27 can remain connected to each other at the second longitudinal end 17 in storage position A.
[0082] Furthermore, Figures 1B and 1C show that the front bracket segments 33 and 39, when the ring bracket 13 is in its closed position C and in the operating position H, form a U1 shape, while the rear bracket segments 35 and 41 also form a U2 shape. In the operating position H, where the bracket segments 33, 35, 39, and 41 are not pivoted relative to each other at the second joints 31 and 37, the U1 and U2 shapes are, in a sense, mirror images of each other, with their respective legs facing each other. By folding into storage position A, the U-shape U2 of the rear shackle segments 35 and 41 can be pivoted into the U-shape U1 of the front shackle segments 33 and 39, so that the lock 11 forms a U-shape overall in storage position A.Furthermore, the longitudinal ends 15 and 17 of the ring bracket 13 are arranged directly adjacent to each other in the storage position A, whereas the longitudinal ends 15 and 17 are opposite each other in the operating position H and in the closed state C of the ring bracket 13 and are separated from each other by the interior space 19 enclosed by the ring bracket 13.
[0083] Folding the ring shackle 13 into storage position A therefore makes it possible in particular to transfer the ring shackle 13 and thus the lock 11 into a compact arrangement, in order to be able to transport the lock 11 comfortably, for example while riding a bicycle.
[0084] Figures 2A and 2B further illustrate the design of the locking device 23 formed at the second longitudinal end 17, wherein the aforementioned locking section 47 is formed with a cam 51 formed as a projection at one end of the front bracket segment 39 of the right bracket section 27. At one end of the left bracket section 25 or its front bracket segment 33, an insertion opening 45 is provided, into which the locking section 47 can be inserted along an insertion direction R as a result of the pivoting movement P1 at the first joint 21. In particular Fig. 2B also illustrates that a lock body 63 is arranged on the front bracket segment 33 of the left bracket section 25, wherein a protective housing 65 is hooked onto the lock body 63 at one end 73 of the lock body 63 and is attached to the lock body 63 at another end 75 of the lock body 63 by means of a fastening element 71 designed as a rivet 77.The protective housing 65 also features, in particular, the aforementioned insertion opening 45 for the locking section 47. The design of the components of the locking device 23, and in particular the locking mechanism 18, arranged on the left shackle section 25 and its front shackle segment 33, is further illustrated in Figures 3A and 3B.
[0085] As can be seen from these figures, the locking device 23 has, in particular, a rotary bolt 49 that is rotatable about a pivot axis D oriented perpendicular to the insertion direction R and which can be actuated by a locking cylinder 57 operated by the aforementioned key 61 (see also Figs. 4A and 4C). The locking device 23 is therefore designed as a purely mechanical locking device 23 in the embodiment shown. Alternatively, however, it would also be possible, for example, to design the locking device 23 as an electromechanical locking device, in which, for instance, an electric drive could be used to actuate the rotary bolt 49 instead of the locking cylinder 57.
[0086] The locking cylinder 57 is rotatable about a pivot axis B aligned parallel to the insertion direction R, which is thus perpendicular to the pivot axis D of the rotary bolt 49. Furthermore, Figures 3A and 3B show that the rotary bolt 49 is biased in the direction of a locking position V by a torsion spring 85, as will be explained in more detail below (see also Figures 4A to 4C).
[0087] The lock body 63 is specifically designed to house the locking cylinder 57 and the rotary bolt 49. To accommodate the locking cylinder 57 and the rotary bolt 49, the lock body 63 therefore has a mounting opening 99. Furthermore, a groove 91 is formed on the locking cylinder 57, and a pin 79 is provided which, when the locking cylinder 57 is inserted, can be guided through respective openings 101 in the lock body 63 to engage in the groove 91 and thereby axially fix the locking cylinder 57 in the lock body 63.
[0088] The aforementioned protective housing 65 is specifically designed to protect the locking cylinder 57 and the rotary bolt 49 from unauthorized access and to close the mounting opening 99. As illustrated in Figures 3A and 3B, the lock body 63 has a slot 67 at end 73 into which a tongue 69 formed on the protective housing 65 can be inserted to hook the protective housing 65 onto the lock body 63. At the end 75 of the lock body 63 opposite end 73, openings 93 are formed in the lock body 63, and the protective housing 65 has corresponding openings 93, so that the protective housing 65 can be attached to the end 75 of the lock body 63 by means of the rivet 77, which is guided through the openings 93 of the lock body 63 and the protective housing 65.Therefore, the protective housing 65 can be easily attached to the lock body 63 by simply hooking it onto the end 73 and then fastening it to the other end 75 using a single fastening element 71, the rivet 77.
[0089] Furthermore, Fig. 3B shows in particular that two retaining projections 83 are formed on the protective housing 65, while openings 81 are formed on the front shackle segment 33 of the left shackle section 25. In the assembled state, the retaining projections 83 of the protective housing 65 engage in the openings 81 of the shackle segment 33 to prevent the shackle segment 33 from slipping off the protective housing 65. In addition, the rivet 77 prevents the openings 81 of the shackle section 25 from loosening from the retaining projections 83, so that the front shackle segment 33 is trapped between the protective housing 65 and the rivet 77, and thus between the protective housing 65 and the lock body 63, and cannot be detached from the lock body 63.
[0090] Figures 4A to 4C illustrate the locking and unlocking of the bracket sections 25 and 27 to each other.
[0091] As already explained, the rotary bolt 49 is biased by the torsion spring 85 into a locking position V illustrated in Fig. 4A, in which a removal recess 53 formed on the rotary bolt 49 points opposite to the insertion direction R and is oriented towards the insertion opening 45. In addition, an eccentric 55, which can be driven by the locking cylinder 57 and is rotationally coupled to the locking cylinder, rests against a stop 95 formed on the rotary bolt 49, with a recess 97 formed on the rotary bolt 49 adjoining the stop 95.
[0092] Due to this arrangement of the rotary bolt 49 and its design with the recess 97, the rotary bolt 49 can be rotated out of the locked position V by inserting the locking section 47 through the cam 51 against the preload of the torsion spring 85 (counterclockwise in the figures), whereby the eccentric 55 can be guided in the recess 97 during this rotation. The cam 51 can, in particular, engage against the limits of the removal recess 53 to achieve the rotation of the rotary bolt 49 by transmitting a tangential force.
[0093] As shown in Fig. 4B, however, after the locking section 57 has been fully inserted, the rotary bolt 49 can, due to the preload provided by the torsion spring 85, rotate back into the locking position V, so that automatic locking can be achieved as a result of the insertion of the locking section 47 into the insertion opening 45. If, in the position illustrated in Fig. 4B, the front bracket segment 39 of the right bracket section 27 is pulled against the insertion direction R in order to separate the two bracket sections 25 and 27, a tangential force is transmitted to the rotary bolt 49 via the cam 51, which could, in principle, cause it to rotate in the opposite direction to the rotation during the insertion of the locking section 47, i.e., in the figures, in a clockwise direction.However, since the eccentric 55 abuts the stop 95 of the rotary latch 49, such a rotation of the rotary latch 49 is blocked and the locking section 47 of the front bracket segment 39 of the right bracket section 27 cannot be removed from the insertion opening 45.
[0094] Consequently, it is necessary to actuate the locking cylinder 57 in order to remove the locking section 47. As shown in Fig. 4C, by a corresponding rotation of the locking cylinder 57, the rotary bolt 49 can be moved into an unlocking position W, with the eccentric 55 carrying the rotary bolt 49 over the stop 95. This allows the removal recess 53 to be positioned in a path of movement which the cam 51 describes when the locking section 47 is released from the insertion opening 45, so that the shackle sections 25 and 27 can be separated from each other and the ring shackle 13 can be moved into the open state O.
[0095] Fig. 5 further illustrates that the closing section 47 is formed by the sleeve 87 already mentioned in connection with Fig. 1A, which is biased by a spring 89 towards the left shackle section 25. In the open state O of the ring shackle 13, the sleeve 87 therefore covers the closing section 47 to protect it (cf. Fig. 1A). However, due to the pivoting movement P1 at the first joint 21, the sleeve 87 can abut a boundary of the insertion opening 45 and be pushed back against the force of the spring 89 to allow the closing section 47 to be inserted into the insertion opening 45.
