Definitions

  • the invention relates to an electronic padlock with a lock body and at least one shackle, which can be optionally locked to the lock body or detached from the lock body.
  • the lock body comprises a first insertion opening for inserting a first insertion section of the at least one shackle and a second insertion opening for inserting a second insertion section of the at least one shackle into the lock body, wherein the first insertion section of the at least one shackle and the second insertion section of the at least one shackle are connected to one another by a connecting section and can be inserted into the first insertion opening and the second insertion opening along an insertion direction.
  • the lock body further comprises an electromechanical locking device with a cam that can be rotated about an axis of rotation and with an electric motor for driving the cam, as well as a control circuit.
  • Such padlocks can be used in particular to guide the shackle through or around a section of an object to be secured, in order to then form a closed loop from the shackle and the lock body by locking the shackle to the lock body and thereby secure the object.
  • the shackle of a padlock for securing a door or flap can be guided through an eyelet of a hasp and then locked to the lock body to prevent the door or flap from being opened.
  • padlocks can be used, for example, to secure two-wheelers, in particular bicycles, against theft or unauthorized driving away, for which purpose the shackle of the padlock can be guided around a frame section of the two-wheeler and around a stationary object, for example a bicycle stand, and then locked to the lock body so that the frame section of the two-wheeler is securely connected to the stationary object and the two-wheeler is connected to the stationary object.
  • the shackle can also be guided around a spoke of a wheel of the two-wheeler in such a way that the padlock prevents the wheel from turning after the shackle is locked and secures the two-wheeler against unauthorized driving away.
  • padlocks By designing the padlock electronically and having an electromechanical locking device, a convenient way for the user to handle the padlock can be created without, for example, having to carry a mechanical key to operate the padlock.
  • padlocks can be used for a variety of different applications, it may be desirable to be able to adapt the padlock flexibly to the requirements of the respective application and to be able to use a single padlock, for example, to secure a door or hatch or to secure a two-wheeler. To achieve this, it may be necessary, for example, to be able to connect different shackle to the lock body in order to create loops of different sizes from the shackle and the lock body.
  • control circuit is designed to control the electric motor for driving the cam optionally into the locking rotary position, the unlocking rotary position or the removal rotary position.
  • the shackle By allowing the cam to be selectively rotated into the locking rotation position, the unlocking rotation position or the removal rotation position, the shackle can be selectively locked to the lock body, held to the lock body via the lower holding section of the first insertion section or completely released for release from the lock body.
  • the second insertion section can be detachable from the lock body in the unlocking rotation position of the cam, so that the loop formed by the lock body and the shackle in the locked state of the shackle can be opened by moving the cam into the unlocking rotation position, but without the shackle having to be completely released from the lock body.
  • the bracket can be designed as a substantially U-shaped, rigid U-bracket and have a long leg and a short leg, wherein the long leg can form the first insertion section and the short leg the second insertion section.
  • the short leg of the U-bracket can be detachable from the lock body, while the long leg of the bracket is held on the lower holding section by the cam.
  • the U-bracket held on the lower holding section of the first insertion section on the lock body can be rotated around the long leg in the unlocking rotational position of the cam. be pivotable in order to be able to guide the bracket comfortably around a section of an object to be secured.
  • the first insertion section connected to the second insertion section via the connecting section can also be moved along the insertion direction, so that the upper locking notch can be arranged at the same height as the cam by inserting the bracket and the bracket can then be locked to the lock body by rotating the cam into the locking rotation position and engaging the cam in the locking notch of the first insertion section.
  • While the unlocking rotational position of the cam can thus enable the second insertion section to be released from the lock body in order to release a secured object or to guide the shackle around a section of an object to be secured without the shackle having to be completely separated from the lock body, rotating the cam to the removal rotational position also enables the lower holding section of the first insertion section to be released and the shackle to be optionally completely released from the lock body.
  • such a complete release of the shackle can be provided in order to be able to separate a relatively long or large U-shackle for securing a bicycle from the lock body and to be able to guide it comfortably around a frame section of the bicycle and a stationary object, whereupon the shackle can be reinserted into the lock body and locked by turning the cam into the locking position.
  • the removal position of the cam can thus enable comfortable operation of the padlock in situations in which the lock body and the shackle have to be brought together from different sides, for example, in order to secure an object.
  • the removal rotation position of the cam can make it possible to optionally connect different shackle to the lock body and thereby increase the flexibility of the electronic padlock.
  • a shackle of a different type can be inserted so that the lock body can be used with a U-shackle, a chain shackle or a rope shackle, for example.
  • the possibility of completely detaching the shackle from the lock body means that different shackles of basically the same type, such as different U-shackles but different sizes, different materials and/or different diameters, can be optionally connected to the lock body in order to be able to use shackles adapted to different requirements or conditions.
  • the cam Since the cam is further designed to engage in the upper locking notch of the first insertion section in the locking rotation position, the cam can in particular make direct mechanical contact with the locking notch.
  • the cam cannot in particular only be provided to displace a separate intermediate element, in particular a bolt, for example a spherical bolt, in the direction of the first and/or the second insertion opening of the lock body or - in the unlocking rotation position or the removal rotation position - to release it for a movement radially inwards with respect to the axis of rotation of the cam in order to lock the shackle or to release it for release from the lock body.
  • the shackle can be locked directly by the cam, without a further locking element being provided.
  • the cam can also be designed to directly mechanically contact the lower holding section of the first insertion section in the unlocking rotation position in order to thereby hold the first insertion section on the lock body.
  • the lower holding section can be designed as a plate-like radial widening of the first insertion section, which strikes the cam when moving out of the lock body when the cam is in the unlocking rotation position.
  • the first insertion section can therefore also be held directly by the cam and not by an intermediate element contacted by the cam, for example a latch.
  • Such direct engagement of the cam in the upper locking notch and direct holding of the lower holding section means that the shackle can be securely and reliably locked to the lock body, since - unlike padlocks known from the prior art with bolts driven by a cam - no intermediate elements are required to lock the shackle, which in any case can in principle offer opportunities for manipulation. Rather, the cam can provide a single stable locking element.
  • the cam can also be secured axially, in particular by a stop on a stable housing of the padlock, so that forces developed by pulling on the shackle can be diverted directly to the housing in the course of a break-in attempt.
  • the diameters of the insertion sections can be coordinated with the diameters of the insertion openings in such a way that any objects can be inserted through the insertion openings to manipulate the rotational position of the cam and the cam cannot be moved out of the locking rotational position by unauthorized persons.
  • the reduction in the components of the electromechanical locking device and the elimination of intermediate elements driven by a cam result in simplified assembly of the padlock, since a smaller number of components have to be incorporated into the lock body.
  • the at least one bracket can be designed in particular as a rigid U-bracket, wherein the first insertion section and the second insertion section can be formed by respective legs of the U-bracket.
  • the first insertion section can be formed by a long leg of the U-bracket and the second insertion section can be formed by a short leg of the U-bracket, although embodiments with legs of equal length can also be provided.
  • the connecting portion can be formed by a rigid, in particular curved portion, which connects the two legs.
  • the bracket can be designed, for example, as a flexible cable or chain bracket, in which the insertion sections can be designed in particular by respective blocks which are connected to one another by a flexible connecting section designed as a cable, in particular a wire cable, or chain.
  • the cam is designed to continue to engage in the upper locking notch of the first insertion section in the unlocking rotational position, but to release the second insertion section for release from the lock body, since a partial release of the first insertion section is not necessarily required in a cable or chain lock due to the flexible connection to the second insertion section in order to be able to release the second insertion section from the lock body. Therefore, the first insertion section of a cable or chain lock does not necessarily have to have a lower holding section.
  • the second insertion section may have a further locking notch and the cam may be designed to also engage the further locking notch in the locking rotational position in order to directly lock both the first insertion section and the second insertion section.
  • the second insertion section can be detachable from the lock body in the unlocking rotational position of the cam.
  • the second insertion section can be formed in particular by a shorter leg of a U-bracket with a long and a short leg, wherein the U-bracket can be pivoted about the lower holding section formed on the long leg, in particular in the unlocking rotational position of the cam.
  • the insertion sections can also be formed by respective blocks connected to one another, for example by a rope or a chain, wherein the block forming the second insertion section can be detachable from the lock body when the cam is in the unlocking rotational position.
  • the first insertion section may have a greater extension than the second insertion section with respect to the insertion direction, wherein the bracket may be pivotable about the first insertion section in the unlocking rotational position of the cam.
  • first locking section can be aligned in the direction of the first insertion opening when the cam is rotated into the locking rotation position
  • the blocking section can be aligned in the direction of the first insertion opening when the cam is rotated into the unlocking rotation position.
  • both the first locking section and the blocking section can have a radial extension such that the first locking section and the blocking section engage in the first insertion opening when the cam is rotated into the locking rotation position or the unlocking rotation position.
  • the first locking section can rest against a boundary, in particular a lower boundary, of the first locking notch when the shackle is inserted into the lock body and the cam is in the locking rotation position, and the blocking section can rest against the holding section when the shackle is inserted into the lock body and the cam is in the unlocking rotation position.
  • the release section can have a radial extension such that the release section does not engage in the first insertion opening when the cam is rotated into the removal rotational position, so that the first insertion opening can be released in the removal rotational position of the cam and the first insertion section can be completely removed from the first insertion opening.
  • the axis of rotation of the cam can be aligned parallel to the insertion direction and the first insertion opening and the second insertion opening can be arranged radially offset from the axis of rotation of the cam.
  • the first insertion opening and the second insertion opening can also open into respective insertion channels extending along the insertion direction, into which the first insertion section and the second insertion section of the bracket inserted into the lock body can extend.
  • the first locking portion can be designed to engage in such an insertion channel when the cam is rotated into the locking rotational position
  • the blocking portion can be designed to engage in the insertion channel when the cam is rotated into the unlocking rotational position
  • the release portion can be designed not to protrude into such an insertion channel when the cam is rotated into the removal rotational position and the release portion is aligned in the direction of the insertion channel.
  • the cam can also have a further release section which is offset radially inwardly relative to the blocking section and which is aligned in the direction of the second insertion opening in the removal rotational position of the cam.
  • the further release section can in particular have a radial extension with respect to the rotational axis of the cam, which corresponds to a radial extension of the release section.
  • the The further release section can be designed not to engage in the second insertion opening or a second insertion channel when the cam is rotated into the removal rotation position.
  • the cam engages neither in the first insertion opening nor in the second insertion opening in the removal rotation position, so that a removed shackle can be inserted into the lock body without striking the cam and thereby damaging the cam or another component of the electromechanical locking device.
  • the cam can have an unlocking section which is aligned in the direction of the second insertion opening in the unlocking rotational position of the cam.
  • the extension of the unlocking section of the cam in the radial direction can in particular be such that the unlocking section does not engage in the second insertion opening in the unlocking rotational position, so that the second insertion section can be released from the lock body when the cam is in the unlocking rotational position.
  • the unlocking section can in particular be offset radially inwards with respect to the blocking section and/or have a radial extension corresponding to the release section and/or the further release section.
  • the cam can be moved from the locking rotation position by rotation along a first rotation direction into the unlocking rotation position and by rotation along a second rotation direction opposite to the first rotation direction into the removal rotation position. Due to such an opposite rotation of the cam during operation of the padlock, that section of the cam, in particular the said first locking section, which in the locking rotation position of the cam engages in the upper locking notch of the first insertion section, can only be rotated slightly and in particular by less than 90 degrees out of the locking rotation position.
  • the section of the cam engaging in the locking notch can define a maximum radial extension of the cam, which is deflected by rotating the cam out of the locking rotation position relative to a connecting line between the insertion openings. Since this deflection can be kept small by rotating the cam along opposite directions of rotation, the extension of the lock body required to enable the rotational movements of the cam can also be limited along a transverse direction aligned perpendicular to the connecting line between the insertion openings, so that a narrow design of the lock body can be achieved.
  • the counter-rotation of the cam enables a reduction in the extension of the lock body in the transverse direction in embodiments explained in more detail below, in which the cam has a second locking section in order to also engage in a locking notch formed on the second insertion section in the locking rotation position, so that the cam is deflected on both sides relative to the connecting line between the insertion openings when rotating starting from the locking rotation position.
  • the cam can be moved from the locking rotational position into the unlocking rotational position by a rotation of less than 45 degrees, in particular by a rotation of 30 degrees or less than 30 degrees.
  • the cam can be moved from the locking rotational position into the removal rotational position by a rotation of less than 45 degrees, in particular by a rotation of 30 degrees or less than 30 degrees.
  • it can be alternatively or additionally provided that the cam can be moved from the unlocking rotational position into the removal rotational position by a rotation of less than 90 degrees, in particular by a rotation of 60 degrees or less than 60 degrees.
  • a narrow construction of the lock body can be realized by carrying out only such slight rotational movements.
  • the lock body can have a maximum extension in a transverse direction oriented perpendicular to the insertion direction and perpendicular to a connecting line between the first insertion opening and the second insertion opening, which is less than a maximum extension of the cam in a plane oriented perpendicular to the insertion direction.
  • the lock body can be designed to be particularly narrow and extend primarily along the connecting line between the first insertion opening and the second insertion opening. Such a narrow design of the lock body can be achieved in particular in embodiments in which the cam does not have to be rotated by 90 degrees or more along a direction of rotation in order to be moved between the locking rotation position, the unlocking rotation position and the removal rotation position.
  • the upper locking notch can be rectangular in cross-section and have a flat boundary surface which is designed to rest against a flat stop surface of the cam when the shackle is locked to the lock body.
  • a flat contact can enable the first insertion section to be held in a positive-locking manner by the cam.
  • the boundary surface and the stop surface can also be aligned in particular perpendicular to the insertion direction, so that the boundary surface and the stop surface can be aligned in particular perpendicular to a force to be developed by pulling on the shackle during a break-in attempt, in order to prevent a diversion of such a force, which could possibly lead to a torque exerted on the cam, and to achieve a secure locking.
  • the second insertion section may have a further locking notch, wherein the cam may be designed to engage in the further locking notch in the locking rotation position and the further locking notch in the unlocking rotation position to release.
  • the cam can have a second locking section which is designed to engage in the further locking notch in the locking rotational position of the cam.
  • the second locking section can in particular have a radial extension corresponding to a radial extension of the already mentioned first locking section.
  • the further locking notch can be designed to correspond to the upper locking notch of the first insertion section and can be rectangular in cross section, for example.
  • the upper locking notch of the first insertion section and the further locking notch can be arranged axially at the same height with respect to the insertion direction when the shackle is inserted into the lock body.
  • the first locking section and the above-mentioned second locking section can be offset from one another by less than 180 degrees with respect to the axis of rotation.
  • the axis of rotation of the cam can in particular be arranged off-center with respect to the lock body and/or not intersect a connecting line from the first insertion opening to the second insertion opening, in particular a connecting line between respective centers of the insertion openings.
  • Such an off-center arrangement can in particular make it possible to provide space for further components of the electromechanical locking device and/or the control circuit on a side of the lock body facing away from the axis of rotation.
  • a sensor for detecting the bracket and/or the rotational position of the cam can be arranged on this side, as explained in more detail below.
  • the holding section can be formed by a circumferential radial widening of the first insertion section, wherein the holding section can be formed in particular at a lower end section of the first insertion section. Furthermore, the holding section can in particular have a flat contact surface which can strike the aforementioned stop surface of the cam when the cam is rotated into the unlocking rotation position.
  • the lock body can also have a pre-tensioning element which is designed to pre-tension the bracket inserted into the lock body in the opposite direction to the insertion direction.
  • a pre-tensioning element can ensure that the first insertion section and thus the bracket as a whole are forced out of the lock body when the cam is rotated into the unlocking position, so that the user of the lock does not have to pull the bracket out of the lock body separately.
  • the pre-tensioning element can serve to hold the lower holding section in contact with the cam when the cam is rotated into the unlocking position, for example to enable a U-bracket to pivot around a long leg without the bracket being able to slip back into the lock body.
  • the pre-tensioning element can be designed as a spring, for example.
  • the lock body may comprise a lock for the shackle, which is designed to hold the shackle inserted into the lock body against the preload in the lock body.
  • the lock can be designed to hold the shackle inserted into the lock body in the lock body in such a way that the upper locking notch of the first insertion section is arranged axially with respect to the axis of rotation of the cam at the same height as the cam, so that the cam can be moved into the locking rotation position without striking the insertion section.
  • the lock can thus serve in particular to hold the shackle against the preload in a position in which the cam is released for trouble-free rotation into the locking rotation position, so that a user of the padlock does not have to hold the inserted shackle against the preload in order to be able to lock the shackle.
  • the lock can be designed to hold the bracket on the lower holding section of the first insertion section.
  • the lock can be arranged in alignment with the first insertion opening in order to be able to hold the bracket in the lock body via the first insertion section.
  • the lock can only be designed to hold the shackle in the lock body against the pre-tension, but without performing a safety-related function with regard to locking. Locking can instead be achieved by the cam engaging in the locking notch.
  • the lock can therefore be made of die-cast zinc or plastic and can therefore be manufactured in a simple manner.
  • the cam may be configured to contact the lock upon rotation from the locking rotation position to the unlocking rotation position and to move it to a release position in which the lock releases the shackle for release from the lock body.
  • the lock can be pivoted between a locking position, in which the lock holds the shackle inserted into the lock body in the lock body, and the release position, and the cam can be designed to contact the lock with a driver section of the cam during a rotation from the locking rotation position to the unlocking rotation position and to pivot it into the release position in order to release the shackle for release from the lock body.
  • the lock held in the release position by the driver section can be pushed under the cam, in particular by the shackle, and the lock can also be pre-tensioned in the direction of a locking position, so that the lock can automatically snap back into the locking position and hold the shackle as a result of the pushing under the cam, in particular under the driver section.
  • a pivot axis of a pivotable lock can be guided axially with respect to the insertion direction in a groove in order to enable an axial movement of the lock to push the lock under the cams and a pivoting of the lock pushed under the cams into the locking position.
  • the lock can be moved axially in the opposite direction to the insertion direction as soon as the lock is released for such axial movement by the cam, in particular a driver section of the cam.
  • the lock can be pre-tensioned in the opposite direction to the insertion direction, or the axial movement of the lock released by the cam can occur in the opposite direction to the insertion direction due to the pre-tensioning of the bracket already mentioned.
  • the axial movement of the lock in the opposite direction to the insertion direction can, however, be limited by a boundary surface of the upper locking notch of the first insertion section striking a stop surface of the cam or by a housing stop provided specifically for the lock on a housing of the padlock.
  • the lock can be arranged axially again in such a way that the lock can be contacted by a driver section of the cam.
  • the locking notch can therefore, in some embodiments, have an axial extent that is greater than the axial extent of the cam, so that the cam can engage in the locking notch in different axial positions of the lock and the held shackle.
  • the lock body may comprise a sensor which is designed to detect when the shackle in the lock body is in a locking position in which the shackle can be locked to the lock body, and to detect when the first insertion section is held on the holding section by the cam positioned in the unlocking rotation position.
  • the sensor may further be designed to transmit respective detection signals to the control circuit.
  • the lock body can comprise such a sensor, in particular a locking position of the shackle and an unlocking position can be detected, wherein the control circuit can in particular be designed to distinguish between the respective detection signals.
  • the upper locking notch can in particular be at the same height as the cam with respect to the insertion direction, so that the cam can be brought into engagement with the upper locking notch without interference by turning it into the locking rotation position.
  • the lock body may include a contact element configured to contact the sensor when the shackle is in the locking position and to release the sensor when the shackle is held by the cam on the holding portion.

Since the axis of rotation D is arranged off-center in the lock body 13, the locking sections 39 and 41 are less than 180 degrees apart from each other with respect to the axis of rotation D.
  • the cam 27 also has a blocking section 43 which is offset radially inwardly relative to the locking section 39, wherein the blocking section 43 can be aligned in the direction of the first insertion opening 17 by rotating the cam 27 along a first direction of rotation D1, in order to thereby enable the bracket 15 to be unlocked (cf. Fig. 5B ).
  • an unlocking section 45 of the cam 27 can also be aligned in the direction of the second insertion opening 19, whereby a complete release of the second insertion section 23 or the short leg of the U-bracket 15 from the lock body 13 can be made possible. This will be explained below using the Figures 4A to 5B explained in more detail.
  • the cam 27 has a driver section 73 pointing in the direction of the lock 59 or the contact element 69. If the cam 27 is controlled for rotation along the first direction of rotation D1 into the unlocking rotation position U, the driver section 73 contacts the lock 59 or the contact element 69, so that the lock 59 or the contact element 69 is pivoted into the release position F against the pretension developed by the pretensioning element 75 and the bracket 15 can thereby be released from the lock 59 for release from the lock body 13 (see in particular Fig. 5A ).
  • the locking surface 103 of the lock 59 can be brought out of engagement with the lower holding section 37, so that the lower holding section 37 can be moved past the lock 59 against the insertion direction E. Due to the pre-tensioning of the bracket 13 against the insertion direction E, the bracket 13 released by the lock 59 can also be pushed directly out of the lock body 13 when the cam 27 is rotated into the unlocking rotation position U, without a user having to transfer a force to the bracket 13 that is opposite to the insertion direction E.
  • the cam 27 is designed to hold the first insertion section 21 in the unlocking rotational position U on the lower holding section 37 and thereby hold the bracket 15 on the lock body 13 (cf. Fig. 4A to 4C ).
  • the holding section 37 which has a larger radial extent than the limits of the locking notch 35, therefore strikes the blocking section 43 due to the prestressing developed by the prestressing element 57, so that the first insertion section 21 cannot be completely released from the lock body 13 and the bracket 15 is held on the lock body 13 when the cam 27 is rotated into the unlocking rotational position U.
  • the unlocking section 45 of the cam 27, which is oriented in the direction of the second insertion opening 19, does not engage in the second insertion opening 19, so that the second insertion section 23 or the short leg of the bracket 15 can be completely released from the lock body 13 in the unlocking rotation position U of the cam 27.
  • This can make it possible, for example, to guide the bracket 15 through an eyelet of a latch in order to be able to securely lock the latch by subsequently locking the bracket 15 to the lock body 13 without the bracket 15 having to be completely released from the lock body 13.
  • the bracket 15 can be pivoted in the unlocking rotation position U, in particular about the long leg or the first insertion section 21, which is held on the lock body 13 (see also Fig. 10E ).
  • the contact element 69 or its contact section 99 does not contact the sensor 61 when the lock 59 or the contact element 69 is in the release position F and the cam 27 is in the unlocking rotational position U.
  • the sensor 61 can consequently transmit a release signal 67 to the control circuit 31, so that the sensor 61 can detect that the shackle 15 is held on the lower holding section 37 and not locked to the lock body 13 in order to transmit a corresponding detection signal, the release signal 67, to the control circuit 31.
  • FIGS. 10A to 10E show, the pivot axis A of the contact element 69 or of the lock 59 is guided on the housing 93 of the padlock 11 axially with respect to the axis of rotation D in a groove 71, wherein a movement of the lock 59 against the insertion direction E is limited in particular by a housing stop 95 formed on the housing 93.
  • This guidance of the pivot axis A in a groove 71 makes it possible to move the shackle 15, which is in the closed position G and locked, together with the lock 59 holding the shackle 15 against the pretension of the pretensioning elements 57 and 75 into a locking position B, in which the shackle 15 is inserted further into the lock body 13 compared to the closed position G (cf. Fig. 6A to 7 ).
  • This mobility of the locked bracket 15 makes it possible to generate an unlocking command by pressing the locked bracket 15 and to transmit it to the control circuit 31, as a result of which the control circuit 31 can control the electric motor 29 to drive the cam 27 from the locking rotational position V into the unlocking rotational position U.
  • an unlocking command can be detected by the control circuit 31 in that the sensor 61 first transmits the first sensor signal 63 and then a second sensor signal 65 to the control circuit 31 when the contact element 69 contacts the lower sensor section 79 as a result of pressing the bracket 15.
  • the control circuit 31 can also be designed to rotate the cam 27 into the unlocking rotation position U only when, in addition to the unlocking command transmitted by pressing the bracket 15, the Fig.1 shown mobile opening device 97, the authentication signal 83 is received at the radio module 81.
  • a radio connection for example a Bluetooth connection, exists between the mobile opening device 97 and the radio module 81, so that the authorized user only has to move with his mobile opening device 97, in particular a smartphone, near the padlock 11 and press the shackle 15 into the lock body 13 in order to be able to open the padlock 11.
  • the axial mobility of the lock 59 or the contact element 69 also makes it possible to hold the bracket 15 released from the lock body 13 after insertion into the lock body 13 in the locking position B, in which the cam 27 can be rotated without interference from the unlocking rotation position U into the locking rotation position V.
  • the Figures 6A to 7 illustrate a position of the bracket 15 and the lock 59 after the bracket 15 and in particular its second insertion section 23 have been reinserted into the lock body 13, wherein the cam 27 is in the unlocking rotation position U.
  • the lock 59 or the contact element 69 can be urged under the cam 27 as a result of the insertion of the bracket 15, in that the inserted bracket 15 moves the lock 59 or the contact element 69 against the pretension of the pretensioning elements 57 and 75 along the insertion direction E.
  • the lock 59 or the contact element 69 comes under the driver section 73 of the cam 27, the lock 59 or the contact element 69 is released for movement into the locking position S, so that the lock 59 or the contact element 69 is pivoted into the locking position S due to the preload developed by the preload element 75 and engages over the holding section 37 of the bracket 15 with the locking surface 103 in order to hold the bracket 15 in the locking position B, in which the locking notches 35 and 55 are arranged at the same height as the locking sections 39 and 41 of the cam 27, so that the cam 27 can rotate smoothly from the unlocking position U into the locking rotational position V.
  • the bracket 15 Since the lock 59 or the contact element 69 is arranged below the cam 27 when the bracket 15 is moved into the locking position B, the bracket 15 must be moved, as it were, beyond the closed position G along the insertion direction E in order to reach the locking position B.
  • the locking notches 35 and 55 have a greater extension than the cam 27 in an axial direction with respect to the axis of rotation D of the cam 27, so that the cam 27 with the locking sections 39 and 41 can engage in the locking notches 35 and 55 both when the bracket 15 is in the closed position G and when the bracket 15 is in the locking position V.
  • control circuit 31 can therefore be designed in particular to control the cam 27 directly from the unlocking rotation position U into the locking rotation position V when the control circuit 31 first receives the release signal 67 and then the second detection signal 65.
  • Such a sequence of the release signal 67 and the second detection signal 65 clearly indicates that the contact element 69 initially by moving the cam 27 into the unlocking rotational position U, it has been released from the sensor 61 and the bracket 15 has reached the open position O, the subsequent second detection signal 65 indicating that the bracket 15 has been moved into the locking position B and that locking should therefore take place.
  • the transmitted second detection signal 65 ensures that the bracket 15 is in the locking position B and that the cam 27 can therefore be rotated into the locking rotational position V without interference.
  • the control circuit 31 can be designed to rotate the cam 27 directly from the unlocking rotational position U into the locking rotational position V if the sensor 61 first transmits the release signal 67 and then the second detection signal 65.
  • the control circuit 31 is designed to rotate the cam 27 into the locking rotation position V only when the locking command 87 is additionally received at the radio module 81, so that the padlock 11 can also be locked exclusively by the authorized user.
  • the cam 27 While the design of the cam 27 thus initially makes it possible to reliably lock the bracket 15 in the closed position G on the lock body 13 or to release it for movement into the open position O, the cam 27 also has a release section 47 which is offset radially inwards with respect to the blocking section 43, wherein the release section 47 can be aligned by rotating the cam 27 starting from the unlocking rotational position U along a second rotational direction D2 opposite to the first rotational direction D1 in the direction of the first insertion opening 17 and the cam 27 can be transferred into a release rotational position R.
  • a release section 47 which is offset radially inwards with respect to the blocking section 43, wherein the release section 47 can be aligned by rotating the cam 27 starting from the unlocking rotational position U along a second rotational direction D2 opposite to the first rotational direction D1 in the direction of the first insertion opening 17 and the cam 27 can be transferred into a release rotational position R.
  • the lock 59 or the contact element 69 is released by the driver section 73 for movement into the locking position S by rotating the cam 27 along the second direction of rotation D2, so that the contact element 69 comes into contact with the sensor 61 and in particular the upper sensor section 67.
  • the sensor 61 can consequently transmit the first detection signal 63 to the control circuit 31.
  • the control circuit 31 is designed to rotate the cam 27 into the removal rotation position R exclusively in response to the release command 85 received from the mobile opening device 97, so that only the authorized user can release the shackle 15 from the lock body 13.
  • Such a complete detachment of the shackle from the lock body 13 can, for example, make it possible to connect a respective shackle 15 from a selection of different shackle 15 to the lock body 13 and to use the padlock 11 flexibly.
  • This option allows the U-bracket 15 shown in the figures to be replaced by a rope and/or a chain shackle, or a larger or smaller U-bracket and/or a U-bracket with a larger and/or smaller diameter to be connected to the lock body 13.
  • shackle 15 made of different materials can generally be connected to the lock body 13 in order to achieve a security standard appropriate to the specific use of the padlock 11.
  • the lock 59 In order to enable the removed bracket 15 or another bracket 15 to be reinserted into the lock body 13 when the cam 27 is in the removal rotational position R, but the lock 59 is in the locking position S, the lock 59 has an inclined contact surface 101, so that the lock 59 can be pivoted into the release position F against the preload of the preload element 75 by inserting the bracket 15, which contacts the inclined contact surface 101. However, as soon as the bracket 15 reaches the closed position G, the lock 59 pivots again into the locking position S due to the preload, so that the locking surface 103 engages over the holding section 37 and the bracket 15 is held in the closed position G by the lock 59 (see in particular Fig. 9B ).
  • the contact element 69 contacts the sensor 61, in particular the upper sensor section 77, as a result of the insertion of the bracket 15, and the control circuit 31 can be designed to rotate the cam 27 from the removal rotation position R into the locking rotation position V as a result of a briefly interrupted contact of the upper sensor section 77 or as a result of a briefly interrupted first detection signal 63, since the insertion of the removed bracket 15 can be detected by this signal sequence.
  • the control circuit 31 can also be designed to control the cam 27 into the locking rotation position V exclusively in response to a locking command 87 received from the opening device 97.
  • it can be necessary to press the bracket 15 inserted into the lock body 13 again into the locking position B in order to transmit a locking command through the contact of the lower sensor section 79.
  • the electromechanical locking device 25 in the embodiment shown also has a measuring device 89 which is designed to detect the rotational position of the cam 27. In this respect, information about the rotational position of the cam 27 can be transmitted directly to the control circuit 31 and taken into account in the control.
  • a user can, based on the Figure 9B shown position, the bracket 15 must move along the insertion direction E so that the sensor 61 is contacted by the contact portion 99 of the contact element 69 on the lower sensor portion 79, wherein the control circuit 31 can be designed to drive the electric motor 29 for driving the cam 27 from the removal rotational position R into the locking rotational position V when the measuring device 89 detects the removal rotational position R and the sensor 61 transmits the second detection signal 65.
  • the lock body 13 can be designed to be narrow and with a small extension along a transverse direction Q that is oriented perpendicular to a connecting line between the insertion openings 17 and 19 and perpendicular to the insertion direction E, wherein the extension of the lock body 13 in the transverse direction Q can in particular be less than a maximum extension of the cam 27 in a plane oriented perpendicular to the insertion direction E.
