Description

The invention relates to a padlock with a lock body and with a shackle, in particular a rigid and essentially U-shaped U-shackle, the shackle having a first leg and a second leg and wherein the lock body has a first insertion channel for introducing the first leg and has a second insertion channel extending parallel to the first insertion channel for introducing the second leg of the bracket.

Such padlocks can be used, for example, to secure a door leaf on a door frame in order to prevent unauthorized opening of the door and to be able to block access to a building or room. For this purpose, the shackle of a padlock can for example be passed through the eyelet of a hold-up and then locked after the legs have been inserted into the insertion channels on the lock body, so that a pivoting or sliding movement for opening the door can be blocked. Padlocks can also be provided for mobile use so that they can be used to secure objects as required. For example, padlocks can be used to securely lock container doors or loading flaps of trucks or to store objects in lockers or lockers in a secure manner for a limited period of time. Padlocks can also be used to securely connect two detached links of a chain and to close the chain, for example to securely connect a two-wheeler to a stationary object such as a bicycle stand or a lantern via the chain.

In particular with such mobile padlocks, which can often be used in different locations and under different external circumstances, the problem arises that a padlock is usually not suitable for each of the applications desired by a user. For example, the diameter of a shackle of a padlock may prove to be too large to block a locker, for example in a sports facility, so that a user cannot use the padlock in question for this purpose. Conversely, a bracket that is too thin cannot offer the necessary or desired security for certain applications. Furthermore, especially in the case of padlocks which are frequently used and which are transported between different locations and which are accordingly regularly opened and locked, it is necessary to provide convenient and simple operability for the user.

Another problem with padlocks with lock cylinders is that a key assigned to the lock cylinder can be lost and the padlock can then no longer be opened by the owner.

It is therefore an object of the invention to create a padlock which enables flexible use for numerous applications with a high level of security and ease of use.

This object is achieved by a padlock with the features of claim 1 and in particular in that the lock body houses a combination locking mechanism, the combination locking mechanism having several rotatable code rings, a first blocking element for securing the first leg in the first insertion channel, a second blocking element for securing the second leg in the second insertion channel and an operating rod which extends between the first insertion channel and the second insertion channel parallel to the first insertion channel and the second insertion channel along an operating axis. Starting from an angular locking position in which the first blocking element and the second blocking element are pushed radially outward with respect to the operating axis into the first insertion channel and the second insertion channel, the operating rod can be rotated about the operating axis along a direction of rotation into an unlocking angular position , in which the first blocking element and the second blocking element are released for movement radially inward. The lock body and in particular the combination locking mechanism are designed so that the operating rod can only be brought into the unlocking angular position when a locking secret is set on the code rings.

The control rod is used to operate the padlock and to be able to open or lock it as desired, in that the legs of the bracket are optionally locked to the lock body. By urging the blocking elements radially outwards with respect to the operating axis, the blocking elements can intervene in the insertion channels in the locking angular position in order to lock the inserted legs of the shackle on the lock body and to block an axial movement of the shackle along the operating axis out of the insertion channels . For this purpose, in the locking angular position of the operating rod, the blocking elements can, in particular, engage in respective retaining depressions formed on the legs and thereby axially fix or hold the legs in the insertion channels. If, on the other hand, the operating rod is moved into the unlocking angular position so that the blocking elements are released for movement radially inward, the Legs are released for axial movement out of the insertion channels in order to be able to detach the bracket at least partially from the lock body. Because the operating rod can be rotated between the locking angular position and the unlocking angular position, the respective position of the blocking elements can be set particularly securely against violent attempts at manipulation, and it is even possible to set additional angular positions (e.g. release angular position), as follows will be explained.

It can be provided here that the operating rod only releases the blocking elements in the unlocking angular position for a movement radially inward, without this movement of the blocking elements already occurring as a result of the rotation of the operating rod. Rather, the blocking elements can be pushed radially inward with respect to the operating axis, in particular by the legs of the bracket being moved out of the respective insertion channels, so that the blocking elements can be moved radially inwards by pulling the bracket in the unlocking angular position of the operating rod by pulling on the bracket to release the legs from the insertion channels. For this purpose, the operating rod can, for example, have a cam or be coupled to one which extends further radially outward in the locking angular position than in the unlocking angular position in order to push the blocking elements radially outward with respect to the operating axis into the insertion channels or release for movement radially inward.

The operating rod can for example be arranged approximately centrally between the first insertion channel and the second insertion channel in order to urge the first blocking element and the second blocking element radially outward into the first and the second insertion channel, respectively. Furthermore, the operating axis can be aligned coaxially to an axis of rotation of the code rings, so that the axis of rotation of the code rings can also be provided centrally between the two insertion channels and the code rings can be arranged axially along the operating axis. The code rings can be rotated accordingly around the operating axis. The first blocking element and the second blocking element can each be in one piece or in several parts, for example the first blocking element and the second blocking element can each have one or two blocking balls or other blocking bodies (e.g. rounded, elongated blocking bodies) mounted in a guide channel of the lock body.

By means of the combination locking mechanism, a rotary movement of the operating rod from the locking angular position into the unlocking angular position can optionally be released or blocked (directly or indirectly, as explained below) by setting or adjusting a locking secret on the code rings. It is therefore necessary to set the locking secret in order to be able to rotate the operating rod so that the padlock can be secured against unauthorized opening by adjusting the locking secret on the code rings. In particular, the code rings can be labeled with numbers in order to be able to set or adjust a predetermined number sequence as a locking secret by rotating the code rings. As an alternative to this, the code rings can also have different shapes or color codings, for example.

By designing the padlock with a combination locking mechanism, the padlock can be operated without a key, so that the risk of being unable to operate the padlock if a key is lost, especially with padlocks that are frequently used and regularly transported, can be excluded. Furthermore, the operation of the padlock, which only requires an adjustment of the code rings, can be made easier compared to an operation with a key and made more comfortable for a user.

If the locking secret is set on the code rings, the operating rod can be moved from the locking angular position to the unlocking angular position by rotating the operating rod (in particular after an axial movement thus enabled, as explained below) around the operating axis along a direction of rotation . It is therefore necessary to first set the locking code in order to release the operating rod for rotation and to be able to reach the unlocking angular position. It can be provided, for example, that a U-bracket can be completely detached from the lock body as a result of moving the operating rod into the unlocking angular position, wherein the legs of the U-bracket can in particular be essentially of the same length. In some embodiments, however, as will be explained below, such a U-bracket can have a short leg and a long leg, with only the short leg in the unlocked angular position of the operating rod being able to be completely detached from the corresponding insertion channel, while the long leg partially remains in the lock body or the associated insertion channel. For this purpose, the first blocking element can be released in the unlocking angular position for a less far-reaching movement radially inward than the second blocking element in order to hold a long leg of a U-bracket in the unlocking angular position in the lock body and the loosened second leg, for example, to be able to pivot the long leg.

If, however, the locking secret is not set, the operating rod is blocked in the locking angular position at least against rotations up to the unlocking angular position and the blocking elements are pushed radially outward into the respective insertion channel in order to lock the inserted legs of the bracket. In particular, if the locking code is not set, the operating rod can be blocked at least against rotations in such angular positions in which the blocking elements are released for sufficient movement radially inward in order to be able to release the first leg and / or the second leg from the respective insertion channel. If the locking secret is not set, the operating rod can therefore at best be rotated about the operating axis between such angular positions in which the blocking elements sufficiently engage in the insertion channels to prevent the legs from loosening. In particular, if the locking code is not set, the operating rod can be fixed in a rotationally fixed manner in the locking angular position with respect to rotations about the operating axis, apart from any manufacturing tolerances.

Provision can be made for at least one further action and / or further movement of the operating rod to be required after the locking code has been set in order to be able to rotate the operating rod into the unlocking angular position. For example, as a result of setting the locking code, the operating rod can be released for an axial movement with respect to the operating axis, in particular out of the lock body, and can only be rotated into the unlocking angular position after such an axial movement. Such an axial movement of the operating rod can also be blocked if the locking code is not set. Furthermore, it can be provided that the operating rod must be released for such an axial movement by an additional action by the user after the locking code has been set, or the axial movement must be actively carried out or initiated before the operating rod can be rotated into the unlocking angular position can.

In this respect, setting the locking secret can be a necessary, but not necessarily a sufficient condition to be able to move the operating rod into the unlocking angular position. In principle, however, it is conceivable that the operating rod can be brought into the unlocking angular position simply by setting the locking code, with the rotary movement of the operating rod in the unlocking angular position in particular having an axial component and, for example, by axially pretensioning the operating rod and via a link guide can be done.

In the context of the present disclosure, all directional information relating to an axis or described rotations, in particular the terms radial and axial, are to be understood in principle as relating to the operating axis, unless another axis is explicitly stated as the reference axis.

Further embodiments of the invention can be found in the dependent claims, the description and the drawings.

In some embodiments, the operating rod can have a cam or be coupled to a cam that cooperates with the first blocking element and the second blocking element.

Such a cam can also be referred to as a rotary latch and be shaped as an eccentric with respect to the operating axis. The cams are used to push the blocking elements radially outward to different degrees in different rotational positions of the operating rod or the cam and thereby optionally to lock the legs of the shackle inserted into the insertion channels of the lock body or to release them for loosening from the lock body. For this purpose, the cam can have several sections along the direction of rotation which differ in their radial extent with respect to the operating axis. In particular, the cam can have a first drive section which extends radially outward in such a way that the first blocking element is forced into the first insertion channel when the operating rod or the cam is brought into the locking angular position and the first drive section in the direction of the first blocking element or the first insertion channel is aligned. Furthermore, the cam can have a first release section which, compared to the first drive section, extends radially outwards less far, so that the first blocking element is released for a movement radially inwards when the cam or the operating rod is in the unlocking angular position brought and the first release portion is aligned in the direction of the first blocking element or the first insertion channel. At the same time, the cam can have a second drive section in order to urge the second blocking element in the locking angular position radially outward into the second insertion channel, and a second release section in order to release the second blocking element in the unlocking angular position for a movement radially inward.

In some embodiments, the cam can be rotatably connected to the operating rod, as will be explained in more detail below. The operating rod can in particular be axially movable relative to the cam with respect to the operating axis, the rotationally effective coupling with the cam being or being able to exist in various axial positions of the operating rod. As an alternative to a two-part design with a rotationally effective coupling, the cam can also be designed in one piece with the operating rod, the cam in particular being able to have a sufficient axial extension along the operating axis to be able to interact with the blocking elements in various axial positions of the operating rod. For example, it can be provided that the operating rod is axially movable with respect to the operating axis as a result of setting the locking secret, wherein the cam can have a sufficient extension in the axial direction to contact the axially immobile blocking elements in all axial positions of the operating rod and depending on the To be able to drive or release the angular position of the operating rod.

In some embodiments, the first blocking element and the second blocking element can be locked in the locking angular position of the operating rod by the cam against a radial retreat inward with respect to the operating axis, and the first blocking element and the second blocking element can be in the unlocking angular position of the operating axis from the cam must be released for a radial movement inward with respect to the operating axis. The cam can be moved into the respective angular position together with the operating rod and, depending on the angular position, have different radial extensions in the direction of the first insertion channel and the second insertion channel in order to block a movement of the blocking elements radially inward in the locking angular position and in to release the unlocking angular position.

It can be provided that the operating rod is coupled to the cam in a rotationally fixed but axially displaceable manner. In particular, the operating rod can be axially movable relative to the cam during operation of the padlock, but remain non-rotatably coupled to the cam (i.e. fixed in rotation) regardless of the axial positions occurring during operation in order to prevent the cam from moving when the locking device moves -Angled position in the unlocking angular position and especially vice versa to be able to take.

In some embodiments, in the unlocked angular position, the cam can extend further in the direction of the first insertion channel than in the direction of the second insertion channel. The first blocking element can consequently be less radially inwardly movable than the second blocking element due to a contact with the cam which already takes place earlier with respect to a radial movement in the unlocking angular position. For example, such a design of the cam can make it possible to release a relatively shorter second leg of a U-bracket in the unlocking angular position from the lock body or to remove it from the second insertion channel, while a relatively longer first leg of the U-bracket in the unlocking angular position by the second blocking element protruding radially into the second insertion channel, even if less far than in the locking angular position, in particular at a lower end portion, can be held in the second insertion channel. The first blocking body can engage in the unlocking angular position, for example, in a holding section of the first leg, which can in particular be designed as a circumferential groove around the U-bracket or the second leg released from the lock body in the unlocking angular position around the first To be able to pivot legs. As a result, starting from the released second leg, the bracket can be comfortably passed through the eyelet of a hold-up, for example, in order to block the hold-up by subsequently inserting the second leg into the second insertion channel and moving the operating rod into the locking angle position and adjusting the locking mechanism.

In the unlocking angular position, the first blocking element can be moved radially inward less than the second blocking element. As explained above, this can enable a comfortable use of the padlock by, for example, a U-bracket can also be held on the lock body in the unlocking angular position and the bracket therefore does not have to be separated from the lock body in order to close the lock with a to connect the securing object.

It can be provided that the first leg of the bracket is longer than the second leg and has a holding section, wherein the second leg can be guided out of the second insertion channel in the unlocking angular position of the operating rod, and the first leg in the unlocking -Angled position of the operating rod can be held on the lock body by engaging the first blocking element in the holding section. In particular, the holding section can be designed as a circumferential groove, so that when the second limb is released, the bracket around the second limb held in the second insertion channel Leg can be pivotable, wherein the bracket can be designed in particular as a U-bracket.

In some embodiments, the operating rod can be rotatable in the direction of rotation from the unlocking angular position into a release angular position in which the first blocking element is released for further movement radially inward. In particular, the operating rod can be rotationally coupled to the aforementioned cam, wherein the cam in the release angular position can have a smaller radial extent with respect to the operating axis in the direction of the first insertion channel than in the unlocking angular position. In particular, the cam can thus have a correspondingly designed third release section. The first blocking element can consequently come into contact with the cam in the release angular position further radially inward than in the unlocking angular position, so that the first blocking element can be moved further radially inward.

In particular, it can be provided that when the locking angle position is normalized to 0 °, the unlocking angle position is reached when the operating rod is rotated about the operating axis by approx. 90 ° and / or that the release angle position is reached when rotating by approx. 135 ° is reached.

In some embodiments, the shackle can be completely detachable from the lock body in the release angular position. Since the bracket is completely detachable from the lock body in the release angular position, while in particular the first leg can be held on the lock body in the unlocking angular position, the bracket can be deliberately and optionally separated from the lock body. The padlock can, however, be opened and locked, and thus used, comfortably and without separating the shackle and lock body. The possibility of being able to optionally detach the bracket from the lock body, in particular, offers additional flexibility in the use of the lock, for example by optionally connecting differently designed brackets to the lock body and locking them to the lock body in order to use the lock for a large number of To be able to use applications optimally. For example, U-brackets of different diameters can optionally be connected to the lock body depending on the application, in particular with regard to a section of the bracket which is arranged outside the lock body even when the legs of the bracket are fully inserted into the insertion channels, in order to be able to use the padlock as required. Furthermore, depending on the application and flexibly, different types of brackets can also be connected to the lock body, for example rope or chain brackets as an alternative to U-brackets, at the ends of which clamps that can be inserted into the insertion channels of the lock body can be formed.

In some embodiments, the first blocking element and the second blocking element can be spherical. In particular, such a spherical design can enable the blocking elements to be easily displaced radially inward when the legs are axially withdrawn from the insertion channels when the operating rod is in the unlocking angular position. A rotation of the operating rod, in particular from the unlocking angular position into the locking angular position, in the course of which the blocking elements are pushed radially outward, can thereby take place smoothly and comfortably. In general, however, the blocking elements can also be shaped differently (e.g. elongated, in particular conical-shaped, with a longitudinal axis oriented radially to the operating axis) and / or constructed in several parts, as already explained.

The operating rod can be locked against rotation from the locking angular position into the unlocking angular position if the locking code is not set on the code rings. The setting of the locking secret can thus represent a necessary condition in order to be able to transfer the operating rod into the unlocking angular position and to be able to open the lock. In particular, apart from any manufacturing tolerances, the operating rod can essentially be held non-rotatably in the lock body if the locking secret is not set on the code rings.

In some embodiments, the operating rod can be axially movable with respect to the operating axis between a blocking position and an operating position. In particular, it can be provided that the operating rod can only be moved axially out of the blocking position into the operating position when the locking code is set. If, on the other hand, the locking secret is not set on the code rings, the operating rod can be blocked in the locked position or an axial movement of the operating rod can be prevented before the operating position is reached, so that the operating position based on the locked position can only be reached when the locking secret is set.

In some embodiments, the operating rod in the (axial) operating position can be rotated from the locking angular position into the unlocking angular position if the code rings - as explained - the locking code is set, although the operating rod is not yet in the (axial) locking position is rotatable, but is locked against rotation from the locking angular position into the unlocking angular position, even if the locking secret is set on the code rings. In particular, it can be provided that the operating rod can only be brought into the unlocking angular position in the operating position. In this respect, in addition to setting the locking code on the code rings, it may initially be necessary to transfer the operating rod from the locked position to the (axial) operating position in order to then be able to turn the operating rod from the locking angle position to the unlocking angle position. In such embodiments it can furthermore be provided that the operating rod is also locked in axial positions between the locking position and the operating position against rotation from the locking angular position into the unlocking angular position.

It can thus be provided in such embodiments that the operating rod can be moved from the locked position to the operating position when the locking code is set on the code rings, whereby an axial movement of the operating rod into the operating position can be blocked if the locking code is not set. In particular, the operating rod can be fixed in the locked position when the locking code is not set, or an axial movement of the operating rod in the direction of the operating position can be prevented before the operating position is reached if the locking code is not set on the code rings. Furthermore, the operating rod can only be rotated into the unlocking angular position when the operating rod is in the operating position, so that by blocking the axial movement of the operating rod if the locking code is not set, the operating rod can also be rotated into the unlocking angular position and accordingly Release of the blocking elements can be blocked for a movement radially inward. It can be provided that the control rod can be transferred directly or automatically to the operating position by setting the locking code on the code rings, while it can also be provided that a further action by the user is required in addition to or after the setting of the locking code, to move the operating rod from the locked position to the operating position. In turn, setting the locking secret can consequently represent a necessary, but not necessarily a sufficient condition for moving the operating rod into the operating position.

The explained two-step movement or the additional axial movement of the operating rod enables advantageous operating concepts, for example to protectively accommodate the operating rod within the lock body or completely within a housing of the lock body when the padlock is closed and the combination locking mechanism is adjusted by moving the operating rod axially into the locked position , or in order to enable the blocking elements to be actuated by the authorized user by an axial movement of the operating rod out of the lock body into the operating position.

In some embodiments, the code rings can be non-rotatably connected to a respective transmission ring, which has a retaining web extending in the circumferential direction on an inner circumference, the retaining webs of the transmission rings being interrupted by a respective unlocking recess and the operating rod having a number of transmission rings corresponding to the number of transmission rings may have radially outwardly projecting locking elevations which, depending on the angular position of the code rings, are aligned with the retaining web of an associated transmission ring or with the unlocking recess of the associated transmission ring.

In particular, the transmission rings can have at least one respective radially outwardly extending coupling bump which engages in a coupling recess formed on an inner circumference of the code rings in order to couple the transmission rings to the code rings in a rotationally fixed manner. Correspondingly, the transmission rings can be rotated together with the code rings in order to align either the retaining web or the unlocking recess of a respective transmission ring in alignment with the corresponding locking projection of the operating rod.

The retaining webs can be interrupted exclusively by the respective unlocking recess and, apart from the unlocking recess, be formed continuously in the circumferential direction. In principle, however, the retaining webs can also be formed by different sections that can be separated from one another by small or narrow interruptions, for example.

In some embodiments, the unlocking recesses of all the transmission rings can be aligned with one another in order to allow the locking elevations of the operating rod to pass axially when the locking code is set on the code rings.

If the locking secret is set on the code rings, a movement of the operating rod axially out of the above can in particular Locked position take place in said operating position, the locking elevations being able to be guided through the respective unlocking recesses during this movement. Correspondingly, the unlocking recesses can be aligned by setting the locking secret in such a way that all of the locking protrusions of the operating rod are aligned with the unlocking recess of the assigned transmission ring. In particular, the locking bumps can be aligned with one another, so that the unlocking recesses of the transmission rings can also be brought into alignment with one another by setting the locking secret. In principle, however, a different alignment of the locking elevations can also be provided, the alignment of the unlocking recesses being coordinated with the alignment of the associated locking elevations in such a way that the locking elevations are aligned with the unlocking recesses when the locking code is set on the code rings.

If, on the other hand, the locking secret is not set, at least one of the unlocking elevations can be aligned out of alignment with the associated locking elevation of the operating rod, so that the locking elevation is arranged in alignment with the corresponding retaining web. An axial movement of the operating rod into the operating position can thus be blocked by the interaction of this locking elevation with the retaining web, so that the operating position cannot be reached if the locking code is not set.

At least one of the retaining webs of the transmission rings can block an axial movement of the operating rod from the locking position into the operating position by contacting the associated locking protrusion if the locking code is not set on the code rings. At least one of the retaining webs can thus be arranged in alignment with the associated locking projection of the operating rod if the locking code is not set on the code rings.

In addition to the locking elevations, the operating rod can have further radial elevations, in particular for blocking the rotation into the unlocking angular position when the locking code is not set or in an axial position of the operating rod that differs from the operating position. The operating rod can also have a radial elevation for coupling with the aforementioned cam.

In some embodiments, the retaining webs can have separating elements extending axially with respect to the operating axis in the direction of the locking position, with the engagement of the respective locking elevation in a space between two separating elements of the associated retaining web in axial positions between the blocking position and the operating position causing a rotary movement of the transmission ring in question connected code rings can block relative to the operating rod.

For example, it can be provided that the operating rod can be moved in the direction of the operating position by an action by a user, but the movement is prevented by at least one retaining web before the operating position is reached if the code rings are not locked. Due to the non-set locking secret or the axial position differing from the operating position, the operating rod can be secured against rotation and held in the lock body in a rotationally fixed manner. Since the locking protrusions of the operating rod can engage in respective spaces between two separating elements in such axial positions, the transmission rings and, accordingly, the code rings connected to the transmission rings in a rotationally fixed manner can also be locked against rotation about the operating axis, which can in particular correspond to its axis of rotation. As a result, successive setting of the locking secret, in particular by an unauthorized person, can be prevented.

If the locking secret is not set and an attempt is made to move the operating rod, in particular unauthorized, into the operating position, an axial movement of the operating rod can be prevented before the operating position is reached and the locking secret can be prevented from being set in such intermediate positions. The locking secret can therefore only be set in the locked position and / or the operating position.

In some embodiments, the operating rod can be moved axially in the direction of the locking position in the unlocking angular position. This can in particular make it possible to change the locking secret. In the unlocking angular position, the operating rod and, together with it, also its locking elevations, are rotated relative to the locking angular position in which the operating rod is moved from the locking position into the operating position. The locking bumps can consequently be arranged in the unlocking angular position out of alignment with the respective unlocking recesses of the transmission rings and instead in alignment with the corresponding retaining webs, so that an axial movement of the operating rod in the direction of the Locked position can be transferred to the transmission rings via the respective retaining webs.

In some embodiments, it can be provided that the transmission rings can be moved axially into a decoupling position relative to the code rings in a decoupling position relative to the code rings during the movement of the operating rod out of the operating position in the direction of the locking position, the non-rotatable connection the transmission rings with the code rings can be canceled in the decoupling position.

It can consequently be provided that an axial movement of the operating rod in the unlocking angular position can be transmitted to the transmission rings in order to be able to move them axially with respect to the operating axis relative to the code rings. For example, in this way respective coupling elevations arranged on the outer circumferences of the transmission rings can be brought out of engagement with coupling depressions which are arranged on the inner circumferences of the assigned code rings. By canceling the non-rotatable connection, the code rings can be rotatable in the decoupling position relative to the transmission rings about their axis of rotation or the operating axis. After the code rings have been rotated, the transmission rings, together with the operating rod, can be brought back axially in the direction of the operating position and thereby into a non-rotatable coupling with the code rings, with the aforementioned coupling bumps in particular now being able to engage in a respective coupling recess at another point on the code rings. The operating rod can then be in the operating position and the unlocking angular position again, with the code rings indicating the changed locking code. In particular, a number of coupling depressions corresponding to the number of numbers or symbols shown on the code rings for forming the locking secret can be formed on the code rings, in which a coupling projection of the respective transmission ring can intervene depending on the relative rotational position of the code rings to the transmission rings.

In some embodiments, the transmission rings can be biased axially with respect to their axis of rotation, which can in particular correspond to the operating axis, against the movement into the decoupling position. When the operating rod is axially moved back in the direction of the operating position, the transmission rings can thereby automatically be moved back into an axial position in which the transmission rings are coupled to the code rings in a rotationally fixed manner. The control rod can also be prestressed in the unlocking angular position in the direction of the operating position, so that the operating rod can automatically be moved back in the direction of the operating position if a user starts this movement releases from the decoupling position of the transmission rings. Furthermore, the operating rod itself can also be pretensioned in the direction of the operating position, independently of the transmission rings.

In some embodiments, the operating rod can be positively guided at least in sections with regard to its axial mobility and its rotational mobility, in particular by a forced guidance (e.g. link guide) in cooperation with the lock body. In particular, rotation of the operating rod into the unlocking angular position can be blocked if the locking code is not set on the code rings and / or if the operating rod is not in the intended axial position (in particular in the mentioned operating position).

In some embodiments, the operating rod can have a guide elevation protruding radially outwardly with respect to the operating axis, which in the locked position of the operating rod engages in a guide channel of the lock body that extends axially with respect to the operating axis Operating axis can be blocked. In particular, walls of the guide channel extending axially with respect to the operating axis can block a rotary movement of the guide elevation and thus of the operating rod when the operating rod is in the locked position. In particular, the guide elevations can also engage in the guide channel in axial positions between the blocking position and the operating position, so that a rotation of the operating rod about the operating axis can be blocked in such axial positions. As a result of the engagement of the guide elevation in the guide channel, rotation in the direction of rotation or from the locking angular position to the unlocking angular position can be blocked, while the operating rod can also be held in the lock body completely non-rotatably by this engagement, apart from any manufacturing tolerances .

In some embodiments, the guide channel can open into a rotary guide channel of the lock body that extends in the direction of rotation, it being possible for the guide elevation to be guided through the rotary guide channel in the operating position of the operating rod. The rotary guide channel can be open on one side, so that the guide elevation does not necessarily during a rotation of the operating rod must be guided on both sides by the rotary guide channel. For example, the rotary guide channel can be arranged on an underside of the lock body opposite the bracket and can be designed to be open on this side. During a rotation of the operating rod, the guide elevation can thus be guided essentially in a depression formed on the underside of the lock body, which recess forms the rotation guide channel.

During an axial movement of the operating rod from the locking position to the operating position, the guide elevation can be guided through the guide channel extending in the axial direction, so that rotations of the operating rod in axial positions between the locking position and the operating position are blocked by the guide elevation engaging the guide channel can. Only when the operating position is reached can the guide elevation be arranged axially in the rotary guide channel and thus be able to be guided through the rotary guide channel in order to enable the operating rod to be rotated into the unlocking angular position.

In some embodiments, the rotary guide channel can form a stop for the guide elevation in the locking angular position. In particular, when the operating rod is rotated back from the unlocking angular position into the locking angular position, reaching it can be clearly detected, so that the rotary guide channel can act as an operating aid and over-rotation beyond the locking angular position can be prevented. Furthermore, the rotary guide channel can also form a stop for the guide elevation in the aforementioned release angular position, so that reaching this angular position can be detected haptically by a user.

In some embodiments, the guide channel can be formed on a guide ring of the lock body, which can in particular be inserted as a separate element in a housing of the lock body. The guide ring can in particular be designed as a hollow cylinder and held firmly in the lock body. Furthermore, the rotary guide channel, into which the guide channel can merge in some embodiments, can also be formed on the guide ring. The guide ring can in particular be arranged or inserted on an underside of a housing of the padlock axially opposite the bracket with respect to the operating axis, wherein the rotary guide channel can be open in particular on this side.

In some embodiments it can be provided that the lock body has a housing, the operating rod in the operating position being able to protrude axially with respect to the operating axis on an underside of the housing, the underside of the housing having respective insertion openings for introducing the first leg into the first insertion channel and of the second leg is axially opposite in the second insertion channel. As a result, the operating rod can be easily reached by a user in the operating position for rotating into the unlocking angular position, without the bracket (arranged at the other end of the housing) making it difficult to reach the operating rod.

In such embodiments, it can also be provided that the operating rod in the (axial) locking position is received completely or essentially completely in the housing of the lock body and is thereby protected.

Furthermore, in some embodiments, the operating rod can be pretensioned axially in the direction of the operating position.

The lock body can have an operating lock which can be released by the user and which optionally blocks a movement of the operating rod due to its axial pretension. Accordingly, even with the locking secret set, the operating rod can initially remain in the locked position and only have to be released for an axial movement into the operating position by releasing the operating lock. Furthermore, the operating rod can be held in the locked position by the operating lock, for example in order to be able to turn the code rings and to be able to set or adjust the locking code. Transmission rings connected non-rotatably to the code rings can thereby be rotatable relative to the operating rod, while such rotational movements can be blocked in positions of the operating rod between the blocking position and the operating position, in particular as explained above.

In some embodiments, the operating lock can have a locking element which is prestressed radially inwardly with respect to the operating axis and which, in the locked position of the operating rod, engages in a holding recess formed on the operating rod. As a result of this radial engagement, the operating rod can be held in the blocking position against its axial bias, in particular also when the locking code is set.

Furthermore, in some embodiments, the operating lock can have an operating element, by means of which the locking element can be moved against the radial prestress and can be brought out of engagement with the holding recess. This also allows the operating rod for an axial movement in the Operating position are released, which the operating rod can execute automatically when the locking secret is set due to its axial pretension, in particular automatically as a result of removing the locking element from the retaining recess. In particular, the operating element can be arranged on an underside of a housing of the padlock, which is axially opposite to the bracket.

In some embodiments, while the operating rod is being transferred from the locking angular position into the unlocking angular position, the locking element can engage in a locking channel of the operating rod extending in the direction of rotation. In particular, as a result of an axial movement of the operating rod into the operating position, the locking element can come into engagement with the locking channel extending in the direction of rotation.

In some embodiments, the locking channel can form a stop for the locking element in the unlocking angular position of the operating rod. The locking channel can be designed as a recess on the operating rod extending in the direction of rotation, in which the locking element engages due to its radial bias after the operating rod has been transferred into the operating position and during a rotation of the operating rod into the unlocking angular position. The locking channel can extend in such a way that the locking element engaging the locking channel strikes one end of the locking channel when it reaches the unlocking angular position and blocks rotation of the operating rod beyond the unlocking angular position. Accordingly, the locking element can function in particular as an operating aid in order to indicate to a user that the unlocking angular position has been reached and to facilitate its precise control. However, it can be provided that the locking element can be deliberately brought out of engagement with the locking channel by means of the operating element in the unlocking angular position in order to be able to move the operating rod further in the direction of rotation, for example, and in particular to be able to transfer it to the aforementioned unlocking angular position.

In some embodiments, the locking channel can merge into a decoupling channel extending axially with respect to the operating axis in the direction of the operating position, the locking element being able to engage in the decoupling channel in the unlocking angular position of the operating rod. The blocking channel and the decoupling channel can in this respect form respective sides of an L-shaped channel. In particular, the engagement of the locking element in the decoupling channel in the unlocking angular position of the operating rod can make it possible to move the operating rod axially in the unlocking angular position in the direction of the locking position in order to transfer the transmission rings relative to the code rings into an uncoupling position and as explained above to be able to adjust.

the 1 A until 1C show a padlock 11th , which has a lock body 13th and a substantially U-shaped bracket 15th with a first leg 17th and a second leg 19th comprises, wherein the first leg 17th via a connection section 21 with the second leg 19th connected is. The first leg 17th of the bracket 15th is in a first insertion channel 23 and the second leg 19th of the bracket 15th into a parallel to the first insertion channel 23 extending second insertion channel 25th introduced to optionally on the lock body 13th locked or for release from the lock body 13th to be released. The insertion channels 23 and 25th extend into a housing 79 of the lock body 13th into it, so that the into the insertion channels 23 and 25th introduced sections of the thighs 17th and 19th are secured against external access.

Around the thighs 17th and 19th in the lock body 13th lock or the padlock 11th To be able to lock, the lock body houses 13th a combination lock mechanism 27 , the one accessible from the outside for a user and around an axis of rotation D. rotatable code rings 29 having. Further comprises the combination lock mechanism 27 how in particular 2 shows a first blocking element 31 to secure the first leg 17th in the first insertion channel 23 and a second blocking element 33 to secure the second leg 19th in the second insertion channel 25th . In addition there are the blocking elements 31 and 33 , as in 2 shown in a locking angular position R1 one with a cam 39 coupled operating rod 35 radial with respect to an operating axis B. along which the control rod is 35 extends outward into respective retaining depressions 115 of the first leg 17th and the second leg 19th pushed to the thighs 17th and 19th in the lock body 13th to lock and against removal from the insertion channels 23 and 25th to lock. The operating axis B. is coaxial with the axis of rotation D. the code rings 29 aligned. By turning around the operating axis B. along a direction of rotation R. can the operating pole 35 into an unlocking angular position R2 be brought into which the cam 39 the first blocking element 31 and the second blocking element 33 for a movement radially inwards with respect to the operating axis B. releases and the thighs 17th and 19th from the respective insertion channels 23 and 25th can be moved out (cf. in particular 3C ).

The code rings 29 of the combination locking mechanism 27 serve in particular to be able to set or adjust a locking secret, which here consists of a sequence of five numbers. It is necessary that the locking secret on the code rings 29 is set to the operating pole 35 into the unlocking angle position R2 to be able to bring and an axial movement of the legs 17th and 19th from the insertion channels 23 and 25th to enable out. If, on the other hand, the locking secret is not set, it is in the lock body 13th introduced stirrups 15th on the lock body 13th locked and in particular the operating rod 35 in the locking angle position already mentioned R1 blocked (cf. 2 , 3A and 3B) .

To set a combination of numbers on the code rings 29 to facilitate is for each of the code rings 29 one by means of a respective spring 101 radial with respect to the axis of rotation D. the code rings 29 marker pen biased inwards 99 provided (cf. 2 ). These marker pens 99 when turning the code rings 29 briefly pushed radially outward against the bias, so that when a new number set as part of the number sequence is reached, it changes to one between the number on the code rings 29 numbers shown, so that the user can haptically grasp the setting of the numbers.

the end 1 A it can be seen that the code rings 29 through window 129 of the housing 79 accessible through the housing 79 formed lateral boundaries 179 the window 129 close to the code rings 29 issue. This tight enclosure prevents thin tools from getting through the window 129 be introduced, for example, to feel the locking secret.

As the 1 A until 1C also show is the operating pole 35 at a bottom 81 of the housing 79 accessible and extends centrally between the insertion channels 23 and 25th along the operating axis B. that are parallel to the insertion canals 23 and 25th is aligned (cf. also 2 ). The operating axis runs here B. coaxial with the axis of rotation D. the code rings 29 so the code rings 29 around the operating axis B. rotatable and axially along the operating axis B. are arranged.

The operating pole 35 is between an in 1A shown locking position S1 , in which the control pole 35 inside the lock body 13th is arranged, and one in the 1B and 1C operating position shown S2 axially with respect to the operating axis B. movable, with a user operating the control rod 35 in the operating position S2 actuate and especially in the unlocking angular position R2 can bring. In the operating position S2 protrudes the control pole 35 on the bottom 81 of the housing 79 out so that the operating pole 35 is easily accessible for the user.

In particular, the operating rod is used 35 to do this, the cam 39 being able to twist around the thighs 17th and 19th of the bracket 15th optionally in the insertion channels 23 and 25th of the lock body 13th to lock or release from the lock body 13th to release. This is the control pole 35 rotatably with the cam 39 connected and can from the locking angle position R1 (see. 3A and 3B) along the direction of rotation R. into the unlocking angle position R2 (see. 3C ) be transferable to the blocking elements 31 and 33 in the locking angle position R1 radial with respect to the Operating axis B. outwards into the insertion channels 23 and 25th to push in and in the unlocking angular position R2 release for a radially inward movement. At its lower, out of the housing 79 the stick has a protruding end 35 a handle portion 36 to a user to operate or rotate the operating rod 35 to facilitate. Further is at the bottom 81 of the housing 79 a control element 90 an operating lock 89 accessible, which the user has to operate in order to control the operating rod 35 in the operating position S2 to be transferred, as will be explained in more detail below (see also 6th and 7th ).

One turn of the operating rod 35 on the cam 39 to be able to transmit, the cam 39 a channel-like in the axial direction with respect to the operating axis B. extending coupling section 59 in which a radial with respect to the operating axis B. from the operating pole 35 protruding coupling section 57 the control pole 35 intervenes (cf. also 4A until 4D ). By turning the operating rod 35 can thereby also the cam 39 be transferred into different angular positions, so that the cam 39 act as rotary latches and the blocking elements 31 and 33 into the insertion channels 23 and 25th push or for a radial with respect to the operating axis B. can release inward movement. The channel-like design of the coupling section 59 of the cam 39 makes it possible to use the control rod 35 axially with respect to the operating axis B. relative to the cam 39 to move, the rotating coupling remains.

As the 3A and 3B show, the cam is in the locking angular position R1 the control pole 35 aligned such that a first drive section 105 in the direction of the first blocking element 31 and a second drive section 109 in the direction of the second blocking element 33 shows. Through the contact of the drive sections 105 and 109 are the blocking elements 31 and 33 in the locking angle position R1 radial with respect to the operating axis B. pushed outwards to get into the holding indentations 115 the thigh 17th and 19th to intervene and the bracket 15th on the lock body 13th to lock (see also 2 ).

Will the operating pole 35 however, in the in 3C Unlocking angular position shown R2 brought the cam 39 brought into a position in which a first release section 107 in the direction of the first insertion channel 23 and thus the first blocking element 31 is aligned and in which a second release section 111 in the direction of the second insertion channel 25th and the second blocking element 33 is aligned. In the unlocking angular position R2 are the first blocking element 31 and the second blocking element 33 therefore for a movement radially inwards with respect to the operating axis B. Approved. By pulling on the bracket 15th can the blocking elements 31 and 33 from the thighs 17th and 19th of the bracket 15th radially inward and out of a path of the legs 17th and 19th be pushed so that the thighs 17th and 19th from the insertion channels 23 and 25th can be guided. The spherical design of the blocking elements makes it possible 31 and 33 their smooth displacement radially inwards.

Here is the cam 39 however designed in such a way that the cam 39 in the unlocking angular position R2 radial with respect to the operating axis B. further in the direction of the first blocking element 31 than in the direction of the second blocking element 33 extends. The first blocking element is corresponding 31 in the unlocking angular position R2 for a less wide movement radially inwards with respect to the operating axis B. released as the second blocking element 33 . As a result, the second, here shorter leg 19th of the bracket 15th in the unlocking angular position R2 completely from the lock body 13th be released while the first blocking element 31 as a result of pulling out the bracket 15th in engagement with one on a lower portion of the longer first leg 17th trained holding portion 37 device and the first leg 17th in the first insertion channel 23 holds (cf. also 2 ). The coat hanger 15th can thus be in the unlocking angular position R2 continue, over the first leg 17th , on the lock body 13th held and by the formation of the holding portion 37 as a circumferential groove around the leg 17th be pivoted so that the short second leg 19th For example, comfortably guided through the eyelet of a hold-up and the hold-up by subsequently inserting the second leg 19th into the second insertion channel 25th can be locked.

As 3D shows, the control pole can 35 and together with the control rod 35 also the cam 39 also in a release angular position R3 are transferred, which starting from the unlocking angular position R2 by a further turn in the direction of rotation R. is attainable. In this release angular position R3 is a third sharing section 113 of the cam 39 in the direction of the first blocking element 31 aligned so that the first blocking element 31 compared to the unlocking angular position R2 for a further movement radially inwards with respect to the operating axis B. is released. This allows the first blocking element 31 in the release angular position R3 also from the holding section 37 of the first leg 17th out radially with respect to the operating axis B. pushed inside and the temple 15th completely from the lock body 13th be solved. This enables the hanger 15th Replace and differently designed brackets with the Lock body 13th to be able to connect. For example, you can optionally use U-brackets 15th different shape and / or different dimensions can be used. During use or opening and locking of the padlock 11th becomes the bracket 15th but on the lock body 13th held so that a comfortable and easy operation of the padlock 11th can be made possible.

As mentioned above, it is necessary that the code rings 29 the locking secret is set to the operating rod 35 from the locking angle position R1 into the unlocking angle position R2 to be able to convict. In addition, such an actuation of the operating rod requires 35 however also that the operating pole 35 in the in the 1B and 1C illustrated operating position S2 is located in which the control rod 35 axially with respect to the operating axis B. from the bottom 81 of the housing 79 of the padlock 11th protrudes (cf. also 8th ). In the locked position S1 as well as in axial positions of the operating rod 35 between the locked position S1 and the operating position S2 is a turning movement of the operating rod 35 however, blocked by a link guide, which is attached to a hollow cylindrical guide ring 73 is formed at the bottom 81 of the housing 79 used and with respect to the lock body 13th is arranged non-rotatably (cf. 5A until 5C as 6th and 8th ).

This guide ring 73 has a guide channel extending in the axial direction 71 in which one is radial with respect to the operating axis B. from the operating pole 35 protruding leadership survey 69 in the locked position S1 as well as in axial positions of the operating rod 35 between the locked position S1 and the operating position S2 intervenes (cf. 5A until 5C as 6th ). Through this intervention by the leadership survey 69 in the guide channel 71 are rotary movements of the operating rod 35 around the operating axis B. blocked in said axial positions, whereas the guide elevation 69 axially with respect to the operating axis B. through the guide channel 71 Can be moved to the operating pole 35 in the operating position S2 to convict.

Towards the bottom 81 of the housing 79 goes the guide channel 71 into a rotary guide channel 75 about where the leadership survey 69 by transferring the control rod 35 in the operating position S2 arrives and which extends in the circumferential direction along the direction of rotation R. extends. The rotary guide channel 75 is in the direction of the bottom 81 open and insofar as one turns in the direction of rotation R. extending depression on the underside 81 trained in which the leadership survey 69 in the operating position S2 the control pole 35 is arranged. The leadership survey 69 is thus in the operating position S2 the control pole 35 for a rotary movement in the direction of rotation R. released and during such through the rotary guide channel 75 maneuverable so that the operating rod 35 in the operating position S2 into the unlocking angle position R2 can be brought (cf. in particular also 8th ).

Furthermore, the rotary guide channel forms 75 a stop 77 for the leadership survey 69 in the locking angle position R1 the control pole 35 (see in particular 5C ). In particular, this stop 77 overturning the operating rod 35 when returning from the unlocking angular position R2 into the locking angle position R1 prevents and the achievement of the correct locking angle position R1 be understandable for the user. With regard to the unlocking angular position R2 the rotary guide channel extends 75 but continue in the direction of rotation R. up to the release angular position R3 so that the leadership survey 69 until the release angular position is reached R3 through the rotary guide channel 75 can be performed. Also in the release angle position R3 forms the rotary guide channel 75 a stop 78 to enable the user to reach the release angular position R3 to be able to display.

In the axial operating position S2 can the operating pole 35 thus in the unlocking angular position R2 be rotated to the blocking elements 31 and 33 for a movement radially inwards with respect to the operating axis B. release and the thighs 17th and 19th of the bracket 15th from the insertion channels 23 and 25th to be able to solve. However, it is about the operating pole 35 in the operating position S2 To be able to transfer, that required on the code rings 29 the locking secret is set. In this respect, the operating pole 35 only then in the unlocking angular position R2 be brought when on the code rings 29 the locking secret is set. Otherwise, in terms of the operating position S2 different axial positions of the operating rod 35 , are rotary movements of the operating rod 35 through the intervention of the leadership survey 69 in the guide channel 71 blocked and those in the insertion canals 23 and 25th introduced thigh 15th and 17th of the bracket 15th secure on the lock body 13th locked. This is explained below using the 4A until 4E explained.

As in particular from the 4A and 4B shows, includes the padlock 11th one of the number of code rings 29 corresponding number of transmission rings 41 , each of the transmission rings 41 non-rotatably with a respective code ring 29 is coupled or can be coupled. The transmission rings show this 41 respective coupling elevations projecting radially outward 51 on which in on an inner circumference 53 the code rings 29 trained coupling depressions 49 intervene to the transmission ring concerned 41 non-rotating with the code ring 29 connect to. One rotation of the code rings 29 around the axis of rotation D. or the operating axis B. to set or adjust the locking secret can thereby directly on the transmission rings 41 be transmitted.

The transmission rings 41 point at their inner circumference 43 a respective retaining bar 45 which extends in the circumferential direction and only through an unlocking recess 47 is interrupted (see in particular 4A until 4C ). At the service pole 35 are like in particular 4C shows one of the number of transmission rings 41 corresponding number of locking bumps 55 formed which with respect to the operating axis B. protruding radially outward and are arranged in alignment with one another.

By setting the locking secret on the code rings 29 can now use the transmission rings 41 be arranged such that the unlocking recesses 47 in alignment with one another and in alignment with the locking elevations 55 which is in the locking angle position R2 located control rod 35 are arranged. This creates the unlocking recesses 47 aligned to the locking bumps 55 the control pole 35 axially with respect to the operating axis B. to let pass, and the operating pole 35 can in particular axially from the locking position S1 in the operating position S2 be transferred (cf. also 1 A until 1C and 8th ).

On the other hand, if the locking secret is on the code rings 29 not set, so is at least one of the transmission rings 41 not the respective unlocking recess 47 , but the retaining bar 45 in alignment with the assigned locking elevation 55 the control pole 35 arranged. An axial movement of the operating rod 35 in the direction of the operating position S2 is thus due to the interaction of the restraint web in question 45 with the associated locking elevation 55 blocked. If the locking secret is not set, the operating rod 35 the operating position S2 therefore do not reach so that the operating pole 35 if the locking code is not set, it is also not in the unlocking angle position R2 can be brought, but through the intervention of the leadership survey 69 in the guide channel 71 of the guide ring 73 compared to rotations around the operating axis B. is blocked (cf. 5A until 5C and 6th ).

On the retaining bars 45 are also several in the circumferential direction in the direction of the locking position S1 extending separators 61 arranged, the locking bumps 55 in a respective space 63 between two dividers 61 advised when the operating pole 35 when attempting to move into the operating position S2 if the locking code is not set in an axial position between the blocking position S1 and the operating position S2 from one of the retention bars 45 blocked. Due to the between the locked position S1 and the operating position S2 rotatably in the lock body 13th held operating pole 35 can through this engagement of the locking bumps 55 in a respective one of the spaces 63 a rotation of the code rings 29 around the axis of rotation D. or the operating axis B. can be prevented, so that successive setting or scanning of the locking secret can be counteracted.

The locking secret must therefore be in the locked position S1 the control pole 35 adjusted, whereupon the operating rod 35 by axial movement into the operating position S2 transferred and then by turning in the unlocking angular position R2 can be brought to the second leg 19th from the second insertion channel 25th to be able to solve. It is also in the unlocking angular position R2 possible to change the locking secret and to set a desired combination of numbers as the locking secret.

In the unlocking angular position R2 are the locking bumps 55 due to the rotation around the operating axis B. compared to the locking angle position R1 , in which the transfer of the control rod 35 from the locked position S1 in the operating position S2 takes place, no longer in alignment with the unlocking recesses 47 , but in flight to the retaining bars 45 arranged (see in particular 4E) . Furthermore, the locking bumps 55 due to the passage through the unlocking recesses 47 in the operating position S2 axially towards the bottom 81 offset from the retaining bars 45 of the respective assigned transmission ring 41 arranged.

This alignment of the operating rod 35 can use the transmission rings 41 by an interaction of the locking bumps 55 with the retaining bars 45 in the course of an axial movement of the operating rod 35 in the direction of the locking position S1 relative to the code rings 29 axially in a decoupling position E. be moved. The locking bumps 55 get at a respective point of attack 48 in contact with the retention bar 45 of the assigned transmission ring 41 and slide the transmission ring 41 in the direction of the locking position S1 , as in 4E exemplary for one of the locking elevations 55 and the associated transmission ring 41 is illustrated. To this axial movement of the operating rod 35 in the unlocking angular position R2 to enable shows the guide ring 73 a decoupling channel extending in the axial direction 97 on by which the leadership survey 69 in the unlocking angular position R2 the control pole 35 is feasible (cf. 5A until 5C ).

As 4D shows, the coupling bumps can 51 the transmission rings 41 by this axial movement out of engagement with the coupling recesses 49 the code rings 29 be brought so that the code rings 29 in the decoupling position E. the transmission rings 41 relative to the transmission rings 41 around its axis of rotation D. or the operating axis B. can be twisted. Will the transmission rings 41 now after such a twisting of the code rings 29 again from the decoupling position E. out and in non-rotatable coupling with the code rings 29 brought the coupling bumps 51 the transmission rings 41 in engagement with another one of the coupling recesses 49 of the assigned code ring 29 than before twisting, so that the locking secret is changed.

The transmission rings 41 are by means of a spring 65 against a movement in the decoupling position E. biased so that the transmission rings 41 automatically engages with the code rings 29 be brought when over the control pole 35 no force in the direction of the locking position S2 on the transmission rings 41 is brought. Also the control pole 35 can through the interaction of the locking bumps 55 with the retaining bars 45 automatically returns to the operating position after changing the locking code S2 get with the operating rod 35 also about another feather myself 67 in the direction of the operating position S2 is biased.

However, to avoid unwanted axial movement of the operating rod 35 due to the preload of the spring 67 to prevent and the locking bumps 55 especially in the locked position S1 outside the spaces 63 the retention bars 45 to keep so the code rings 29 twisted and the locking code can be set or adjusted, is the aforementioned operating lock 89 intended. This has a locking element 85 on, which by one on the guide ring 73 formed engagement opening 103 through and how 7th shows in the locked position S1 the control pole 35 into one at the service pole 35 trained retaining recess 91 intervenes (cf. also 5A and 6th ). This intervention causes the operating rod to move 35 in or in the direction of the operating position S2 blocked, the locking element 85 by means of a spring 87 radially inwards with respect to the operating axis B. and thus in engagement with the retaining recess 91 is biased.

To the handle 35 for a movement into the operating position S2 to release, it is therefore necessary, in addition to setting the locking secret, that the user activates the locking element 85 by means of the control element 90 against the bias out of engagement with the holding section 91 brings. The control rod can then 35 due to the by the spring 67 generated preload 77 automatically to the operating position S2 be transferred (cf. also 7th ). As a result of such movement of the operating rod 35 in the operating position S2 arrives the locking element 85 engaged with one on the control pole 35 trained and moving in the direction of rotation R. extending locking channel 93 in which the control element 85 during a rotary movement of the operating rod 35 into the unlocking angle position R2 is guided accordingly (cf. 9A until 9C ).

In the unlocking angular position R2 goes the blocking channel 93 into one axially with respect to the operating axis B. extending decoupling channel 97 over so that the locking element 85 in the unlocking angular position R2 in the decoupling channel 97 intervenes. The locking channel 93 and the decoupling channel 97 thereby form respective sides of an L-shaped channel, the locking element 85 during a movement of the operating rod 35 in the direction of the locking position S2 to change the locking secret in the manner explained above through the decoupling channel 97 is guided to enable this movement.

The locking channel 93 also forms a stop 95 , through which reaching the unlocking angular position R2 can be detected by a user and it can be ensured that the operating rod 35 not inadvertently via the unlocking angle position R2 is turned out. Also an unintentional loosening of the bracket 15th from the lock body 13th can thus be prevented. Should the control pole 35 however, in the release angular position R3 (see. 3D ) are transferred to the hanger 15th deliberately completely from the lock body 13th To be able to solve, a user can first re-activate the locking element 85 by means of the control element 90 out of engagement with the locking channel 93 bring. The control rod can then 35 continue in the direction of rotation R. until reaching of the rotary guide channel 75 formed stop 78 for the leadership survey 69 and in the release angular position R3 be moved.

The padlock shown here 11th consequently enables extremely flexible use with simple and convenient operability. With the option of using the hanger 15th optionally from the lock body 13th to be able to solve different brackets with the lock body, depending on the needs and the application 13th get connected. During use of the padlock 11th or one Locking or opening is the handle 15th however, on the lock body 13th held so that the padlock 11th can be operated comfortably. By blocking both axial movement of the operating rod 35 as well as a rotary movement of the operating rod 35 if the locking secret is not set, the shackle can also be locked extremely securely 15th on the lock body 13th can be achieved. By having the operating pole 35 is rotatable, the respective position of the blocking elements 31 , 33 can be set particularly precisely and reliably, with several angular positions as explained R1 , R2 , R3 can be adjusted. The axial mobility of the operating rod 35 allows the operating pole 35 with the padlock closed 11th and misaligned combination locking mechanism 27 inside the lock body 13th or the housing 79 and thereby largely protect against attempted break-in or manipulation.
