Description

The invention relates to a ring shackle padlock, comprising a ring shackle rotatable about an axis of rotation, a lock cylinder which has a cylinder housing and a rotatable cylinder core, a driver coupled to the cylinder core for driving the ring shackle, a housing which has a housing front part and a housing rear part, and an insert part in which the lock cylinder is held.

The invention also relates to methods for assembling such ring bracket padlocks.

Ring shackle padlocks are a particularly tamper-proof type of padlock, in which a ring-shaped shackle is permanently held in a housing of the lock. By unlocking the lock cylinder, which can include a locking mechanism, for example with pin or plate tumblers, with a suitable key and rotating the cylinder core relative to the cylinder housing, the ring bracket can be rotated about its axis of rotation between an open position and be moved to a closed position. Typically, the housing can include an indentation released by the ring bracket in the open position, so that the ring bracket can be guided through an object to be secured, for example an eyelet of a hasp or two links of a chain. In the closed position, the ring shackle traverses and blocks the indentation and an object within can be attached to the lock be secured. A possible embodiment of a ring padlock is, for example, in EP 0 872 615 B1 shown.

Ring bracket padlocks can include insert parts that are inserted into the housing and can be used in particular to accommodate and store the lock cylinder. Such insert parts can have, for example, a front plate and a back plate, which can be connected to one another, for example, via a number of pins that are riveted on.

A ring shackle padlock with such an insert, which comprises a front plate and a back plate, is in U.S. 2012/167641 A1 described. In this ring shackle padlock, the front plate and the back plate are inserted in a form-fitting manner into an outer housing of the ring shackle padlock. In addition, the front panel and the back panel have respective connecting surfaces that correspond to one another in order to achieve a form-fitting and planar connection, so that the front panel and the back panel form a stable unit. In addition, engagement bumps are formed on a rear side of the front panel, which engage with receptacles formed on a front side of the back panel, and securely connect the front panel and the back panel to each other.

Furthermore, it is possible to firmly connect such an insert part, formed from a front plate and a back plate, to the housing, for which purpose the insert part can be welded in particular to the housing of the ring shackle padlock. However, the assembly of such ring bracket padlocks turns out to be undesirably complex.

It is therefore an object of the invention to create a ring padlock which allows simplified manufacture and assembly thereof.

This object is achieved by a ring bracket padlock with the features of claim 1.

The shackle padlock has a single integral one-piece insert in which the lock cylinder is retained.

An integral, one-piece insert part is to be understood as meaning a part originally formed as a single material bond, which can be produced, for example, by casting or injection molding. It differs in particular from insert parts that are originally assembled from two or more parts and whose individual components are connected to form a detachable or permanent joint, such as by welding or screwing.

Such an integral one-piece insert allows a simplified and quick assembly of the ring bracket padlock by the number of required Assembly steps is minimized, and can also form a defined leadership of the ring bracket in the housing, as will be explained below.

Directions given in connection with the invention generally relate, unless otherwise stated, to the axis of rotation of the ring bracket.

Possible embodiments can be found in the dependent claims, the description and the drawings.

In some embodiments, the ring yoke may include a peripheral cutout, wherein the insert is adapted to be laterally inserted through the peripheral cutout of the ring yoke into an interior space of the ring yoke. The insert can consequently be inserted into the interior of the ring bracket along the extension plane of the ring bracket or from a direction perpendicular to the axis of rotation of the ring bracket, which means that the two parts can be easily joined together during assembly of the padlock.

The insert part can comprise a holding section with a receiving opening in which the lock cylinder is held in a rotationally fixed manner, the holding section having a minimum width which is less than the clear width of the peripheral section of the ring bracket. The stated width of the holding section relates in particular to the extent of the holding section in the plane of extension of the ring bracket or in a plane normal to the axis of rotation of the ring bracket.

Due to the non-rotatable holding of the lock cylinder in the receiving opening of the holding section, it can be secured and fixed in the insert part against twisting. The receiving opening can be positioned in such a way that the axis of rotation of the cylinder core used is aligned with the axis of rotation of the Ring bracket matches, while it is also possible to arrange the cylinder core eccentrically to the ring bracket.

Furthermore, such a dimensioning of the holding section enables a lateral insertion of the insert part through the peripheral cutout of the ring bracket into its interior, which can simplify the assembly of the ring bracket padlock in particular. The central holding section of the insert part with the receiving opening for the lock cylinder can be cylindrical or circular in cross-section, whereby the holding section can also be designed in such a way that its width or extension is in a specific angular position in relation to the axis of rotation of the ring bracket or the Cylinder core is less than in other angular positions. In general, it can be sufficient if the holding section of the insert part has a width or an extension in at least one angular position that is smaller than the clear width of the peripheral section of the ring bracket. An oval cross section of the central holding section of the insert is also possible, for example.

In some embodiments, the insert may be made of a plastic. As a result, the insert part can have an elasticity, in particular minimal or slight, so that tolerance compensation between the lock cylinder and the housing can be made possible. Furthermore, a sufficiently high level of burglary security of the ring shackle padlock can be achieved, since due to the circular design of the housing and in particular the ring shackle, only relatively small forces or torques can be applied to the insert part in the event of unauthorized opening attempts.

The front part of the housing and the rear part of the housing can be formed by half-shells.

Furthermore, the front part of the housing and the rear part of the housing can be peripherally connected to one another, in particular welded. In this way, a secure and firm connection of the housing parts and thus a stable housing can be formed, so that this can prove resistant to unauthorized attempts to open or break open.

The front housing part and the rear housing part can be connected to one another along a common parting plane.

In some embodiments, the front part of the housing and the rear part of the housing can form a radially inwardly directed indentation, which is traversed by the ring bracket in a closed position of the ring bracket, the insert part captured within the housing being supported against rotational movement by the indentation of the housing. This makes it possible to mount the insert part in the housing in a rotationally fixed manner. Since the lock cylinder in some embodiments can also be surrounded by a holding section of the insert part in a rotationally fixed manner or held in it in a rotationally fixed manner, the ring shackle padlock can be protected in particular against any attempts to open it without authorization by forcibly rotating the shackle or the cylinder housing of the lock cylinder .

In some embodiments, the insert may provide a guide for rotational movement of the ring yoke. As a result, a defined positioning and/or movement of the ring bracket can be achieved, so that, for example, a smooth rotary movement of the ring bracket is possible and noise generation during the closing process can be avoided. Furthermore, the guide can prevent signs of wear and possible wedging of the ring bracket in the lock and in particular on its housing or an insertion opening, into which the ring bracket penetrates the junction in the closed position.

In some embodiments, the guide may also allow for lash adjustment.

The insert part can form a guide for an inner circumference and/or a front side and/or a back side of the ring bracket.

The insert part can have at least one, preferably two, three or four guide section(s) which, viewed along the axis of rotation of the ring bracket, are arranged between an inner peripheral area of the ring bracket and the front part of the housing and/or between an inner peripheral area of the ring bracket and the rear part of the housing /are. In particular, the respective guide section of the insert part can be arranged between a front side of the ring bracket and the front part of the housing and/or between a rear side of the ring bracket and the rear part of the housing. However, the respective guide section does not have to completely cover the front side or the rear side of the ring bracket, but can only overlap with the ring bracket at a radially inner area of the ring bracket. The guiding section or the guiding sections can in particular be wing-shaped or lobed and thin, whereby a defined and smooth guiding of the ring bracket can be achieved with a small space requirement. Furthermore, by arranging guide sections on the ring bracket, possible manufacturing and assembly tolerances of the housing can be compensated for, if necessary, and a possible wedging of the bracket on the housing can be avoided.

The guide section or sections can be formed from an elastic material. In particular, this can also enable manufacturing tolerances to be compensated for and make assembly easier, in that the guide section or sections can be pushed out during assembly of the Can be used with other components, for example, elastically and in particular deformed resiliently.

In some embodiments, the respective guide section can extend at least essentially along a normal plane to the axis of rotation of the ring bracket. This enables an axially flat design of the ring bracket padlock.

As explained above, the insert part can comprise a holding section with a receiving opening in which the lock cylinder is held in a rotationally fixed manner, with the respective guide section protruding from the holding section laterally or in the radial direction with respect to the axis of rotation of the ring bracket. In particular, the holding section can be arranged centrally in the insert part, so that the respective radially protruding guide section can hold the ring bracket spaced radially from the holding section or guide it during a rotary movement.

Provision can be made for the at least one guide section to be deflectable laterally with respect to its extension direction and/or in a direction parallel to the axis of rotation of the ring bracket, with the at least one guide section being able to be deflected in particular elastically. In particular, the at least one guide section can be designed to be resilient after an elastic deflection. Such a deflectable design of the at least one guide section can, for example, facilitate the insertion of the insert part into the interior of the ring bracket, particularly if this insertion is from a lateral direction or a direction perpendicular to the axis of rotation of the ring bracket through a peripheral cutout of the ring bracket. Such a deflection of the at least one guide section can also occur when the insert part is inserted laterally into the interior of the ring bracket if the guide section has a greater extent in the circumferential direction than the clear width of the circumferential cutout of the ring bracket. Further a secure guidance of the ring bracket in the lock can be achieved by the at least one guide section resting against the ring bracket with a non-positive fit.

For the non-positive fit of the at least one guide section on the ring bracket in this and generally the following embodiments, a surface contact or just a linear contact between the respective guide section and the ring bracket can be provided, for example if the respective guide section with an edge or a peripheral area rests against the ring bracket. Full-area contacting or covering is not necessary.

In some embodiments, the insert may have a plurality of guide portions, wherein at least one of the plurality of guide portions is associated with a front peripheral portion of the ring bracket, and at least another one of the plurality of guide portions is associated with a rear peripheral portion of the ring bracket. The ring bracket can be surrounded on two sides by the guide sections, so that the ring bracket can be supported and guided in a stable manner in the axial direction and noise can be avoided, particularly during a movement of the ring bracket from the open position into the closed position or vice versa.

It can be provided that one of the several guide sections bears against the front peripheral section of the ring bracket and the other of the several guide sections bears against the rear peripheral section of the ring bracket. In particular, one and the other of the several guide sections can rest against the front and rear peripheral sections of the ring bracket with a non-positive fit, so that the ring bracket is guided between the one and the other guide section in the axial direction with respect to the axis of rotation.

In some embodiments, viewed along the axis of rotation of the ring bracket, the cross-sectional diameter of the ring bracket relative to the distance between one and the other of the plurality of guide sections can be selected such that one of the plurality of guide sections abuts the front peripheral cutout of the ring bracket with a force fit and the other of the plurality Guide sections on the rear peripheral portion of the ring bracket rests frictionally. In particular, the cross-sectional diameter of the ring bracket can be oversized relative to the distance mentioned, as a result of which the desired non-positive guidance of the ring bracket along the guide sections can be achieved.

In some embodiments, one of the plurality of guide portions abutting the front peripheral portion of the ring yoke and the other one abutting the rear peripheral portion of the ring yoke may be circumferentially offset from one another. For example, three guide sections can be provided in an arrangement of two front and one rear guide section or in the reverse arrangement, with these guide sections offset from one another in the circumferential direction resting against the associated circumferential sections of the ring bracket. As a result, the ring bracket can be guided over a large circumferential area in contact with at least one of the guide sections, so that the ring bracket can be guided in a controlled manner.

Furthermore, the insert part can comprise at least one pair of guide sections, which are axially offset with respect to the axis of rotation of the ring bracket, but are arranged in alignment with one another, one guide section of the pair being assigned to the front peripheral section of the ring bracket and the other guide section of the pair being assigned to the rear peripheral section of the ring bracket is. The guide sections of a pair are arranged at least partially overlapping each other in the axial direction, so that the ring bracket in one The area in which the pair of guide sections is arranged can be encompassed by the guide sections, in particular essentially on both sides.

In particular, it can be provided that one guide section of the pair rests on the front peripheral section of the ring bracket and/or that the other guide section of the pair rests on the rear peripheral section of the ring bracket, with the respective guide sections being able to bear in a non-positive manner. The ring bracket can be encompassed on two sides by the guide sections of the at least one pair, which thereby enable stable mounting and positioning of the ring bracket in the axial direction. Any noise generated during the closing process due to imprecise guidance of the ring bracket can also be avoided in this way.

The insert part can comprise two such pairs of guide sections, which are offset from one another in the circumferential direction with respect to the axis of rotation of the ring bracket. The guide sections of the two pairs can guide the ring bracket in particular on peripheral sections that are essentially diametrically opposite one another, so that reliable guidance of the ring bracket can be achieved over a wide peripheral area. Furthermore, the pairs of guide sections can be arranged on different sides of the indentation traversed by the ring clip in the closed position within the housing, so that the ring clip is guided into the indentation during a transfer from the open position to the closed position, for example surrounded by the first pair and after passing through it the indentation and an insertion into an insertion opening of the housing of the second pair can be received encompassing.

In some embodiments, the cylinder core can have a drive section and the driver can have a connection opening, the drive section of the cylinder core positively engages in the connection opening of the driver. Due to the form-fitting engagement of the drive section of the cylinder core in the connection opening of the driver, a uniform and direct transmission of a rotation of the cylinder core to the ring bracket can be achieved. Furthermore, by being coupled to the drive section of the cylinder core held in the insert part, the driver can be secured against detachment therefrom in the radial direction with respect to the axis of rotation of the ring bracket.

The insert part can comprise a lateral clearance into which the driver is inserted, the driver projecting radially out of the lateral clearance with respect to the axis of rotation and being pivotable in the circumferential direction along the lateral clearance with respect to the axis of rotation of the ring bracket. Due to the radial protrusion of the driver from the lateral clearance or from the insert part, it can be in engagement with the ring bracket spaced radially from the insert part, so that it can be driven by a rotation or pivoting of the driver transmitted from the cylinder core to the driver.

Provision can be made for the ring bracket to have a drive recess into which the driver engages with essentially no play and in particular with a positive fit with respect to its pivoting direction. By engaging the driver in the drive recess, the ring bracket can be moved between a closed position and an open position by rotating the cylinder core using a key and resulting pivoting of the driver. A substantially play-free or form-fitting engagement of the driver in the drive recess in the pivoting direction makes it possible, in particular, to transmit a rotation of the cylinder core directly and without delay to the ring bracket. This also makes it possible to achieve a uniform closing process in relation to the force required to drive the ring bracket, and any noise caused by the driver striking the boundaries of the drive recess can be avoided. In radial On the other hand, the driver can optionally be movably mounted in the drive recess in order to compensate for a possible eccentricity of the axis of rotation of the cylinder core or of the driver relative to the axis of rotation of the ring bracket during pivoting of the driver and movement of the ring bracket.

The insert part can form a limitation of the lateral clearance in the circumferential direction with respect to the axis of rotation, with a pivoting movement of the driver in the circumferential direction being restricted by the limitation. The delimitation formed by the insert part can act in particular in the sense of respective stops against which the driver bears in the closed position or in the open position of the ring bracket. The positions of the driver and correspondingly also of the ring bracket in the closed position and in the open position can be clearly specified and defined by these stops. Furthermore, the driver can be supported by the associated limitation in the circumferential direction, particularly in the closed position of the ring shackle, so that attempts can be counteracted to open the ring shackle padlock without authorization by moving the driver beyond its predetermined position in the closed position of the ring shackle.

In some embodiments, the insert part can have an inner lateral surface of a hollow cylinder section, against which a part of the driver that does not protrude from the lateral clearance is guided during a pivoting movement, wherein the inner lateral surface can extend in particular over an angular range of at least 180° (180 angular degrees). Due to this abutting guidance of the driver within the insert, its movement can be coordinated and uniform. Furthermore, the inner lateral surface can at least partially absorb forces that are applied from the radial direction to the part of the driver protruding from the clearance and, for example, to the housing as a result of impacts, and direct them to the insert part. Through this Supporting the driver in the radial direction, such forces are at least not completely transferred to a cylinder core connected to the driver, so that possible damage to it during such attempts to break open can be counteracted.

In some embodiments, the lateral clearance of the insert can form a lateral bearing opening for the driver, with the insert forming a peripherally closed boundary of the lateral bearing opening, and with the driver protruding radially and/or in the axial direction relative to the peripherally closed boundary of the lateral bearing opening the axis of rotation of the ring bracket is secured against loosening from the cylinder core of the lock cylinder. The lateral bearing opening can in particular be designed in the manner of a slot in order to enable a driver which is designed in particular to be flat to be accommodated and guided with the greatest possible precision.

In such embodiments, the driver can be secured in the radial direction with respect to the axis of rotation of the ring bracket by a connection to the cylinder core, in particular by a positive connection to a drive section of the cylinder core, and in the axial direction by the limitations of the insert part (circumferentially closed limitation of the lateral bearing opening). loosening from the lateral bearing opening must be secured. As a result, the driver is reliably held in the lateral bearing opening and connected to the cylinder core, so that attempts to remove the driver from the cylinder core can be prevented. Furthermore, the assembly of the ring bracket padlock can be simplified in that the insert part, the driver and the lock cylinder can be manufactured as prefabricated parts which can form an intrinsically stable assembly after they have been assembled, as will be explained below.

As an alternative to designing the lateral clearance as a lateral bearing opening (with a peripherally closed boundary), in some embodiments the insert part can have or form an assembly opening on a rear side, into which the driver can be inserted along an axial direction with respect to the axis of rotation of the ring bracket. The lateral clearance can thus be open towards the rear of the insert. When the ring bracket padlock is in the installed state, the back of the insert part points in the direction of the inside of the rear part of the housing.

Since the driver can be inserted into this assembly opening axially with respect to the axis of rotation, the driver can be connected in a simple manner, for example during assembly, to a cylinder core inserted axially into a holding section of the insert part, with a positive connection being achieved in particular by a resulting engagement of a drive section of the cylinder core can be provided in a connection opening of the driver. Furthermore, all the steps for assembling the insert part, the cylinder core and the driver can be carried out from the axial direction during assembly of the ring shackle padlock, with the exclusively linear movements required for this along an axis possibly also being able to be carried out at least partially automatically. In such embodiments, too, the driver can be reliably connected to the cylinder core in the assembled state of the ring bracket padlock in the axial direction, in that the driver can rest, for example, on an inside of the housing rear part and can be secured by this against loosening from the cylinder core.

In some embodiments, the driver can have at least one sliding element on a side facing away from the cylinder core, with which the driver rests on the inside of the housing rear part and/or with which the driver rests on an inside of the insert part. By such Sliding element, a smooth movement of the driver during a pivoting movement for driving the ring bracket from the closed position to the open position or vice versa can be made possible by not using the driver with its entire surface, but only with the at least one sliding element on the inside of the rear part of the housing or an inside of the insert rests, so that the friction to be overcome during a movement of the driver can be reduced.

The at least one sliding element can be in the form of an elevation, in which case the elevation can be in particular pin-shaped, cylindrical, conical, spherical, hemispherical or a truncated cone. A sliding element of this type can, in particular, be an elevation, starting from a surface of the driver in an area in which it does not protrude radially from a lateral clearance of the insert part, in the direction of an inside of the housing rear part or in Extend towards an inside of the insert part. Such an elevation can thus extend in particular from a rear side of the driver or from a side of the driver facing away from the cylinder core in the direction of the rear part of the housing.

By forming such elevations on a surface of the carrier facing the rear part of the housing, it can be achieved that the carrier only rests with these elevations and not with its entire surface on the inside of the rear part of the housing or on an inner side of the insert part and is guided during a movement. so that frictional forces to be overcome can be reduced during a pivoting movement of the driver. For this purpose, in particular several, for example three or five, elevations can be formed on a region of the driver resting on the rear part of the housing or the insert part, in particular along a ring or along several concentric rings can be arranged with respect to the axis of rotation of the ring bracket or the cylinder core.

In some embodiments, the ring shackle padlock can consist exclusively of the ring shackle, the insert part, the lock cylinder, the driver, the front housing part, the rear housing part and optionally a keyhole cover assigned to the front housing part. By providing such a small number of components, the assembly of the ring bracket padlock can be made easier and faster.

The invention also relates to a method for assembling a ring shackle padlock which is designed as explained above and which has a ring shackle which can be rotated about an axis of rotation, a lock cylinder which has a rotatable cylinder core, a driver for driving the ring shackle, a single integral one-piece insert part and a housing having a front housing and a rear housing. The driver is inserted along a radial direction with respect to the axis of rotation into a lateral clearance of the insert part, the lock cylinder is inserted along an axial direction into a receiving opening of the insert part, and the insert part is pushed through along a lateral direction together with the lock cylinder and the driver introduced a peripheral section of the ring bracket in an interior of the ring bracket. The resulting arrangement of insert, lock cylinder, driver and ring bracket is surrounded by the front housing part and the rear housing part, and the front housing part and the rear housing part are permanently connected to one another around the circumference.

Such a method for assembling a ring padlock can be carried out in a simple manner and in a small amount of time, since only a small number of easy-to-carry assembly steps are provided. This can in particular also the cost of producing a Ring shackle padlock can be reduced. Furthermore, at least some of the assembly steps can optionally be carried out in an automated manner due to their simplicity. In particular, if the insert part of the ring shackle padlock to be assembled is formed integrally in one piece, previous or additional steps are also omitted in order to assemble an insert part comprising two or more separate parts, for example.

In the final step, the front part of the housing and the rear part of the housing can in particular be welded to one another in order to achieve a secure and stable connection of these parts to form a housing. The two housing parts can be connected along a parting plane, with the housing parts being able to be designed in particular as half-shells.

As explained, the lateral release of the insert part can form a lateral bearing opening for the driver, with the insert part forming a peripherally closed boundary of the lateral bearing opening, and with the driver being axially guided by the peripherally closed boundary of the lateral bearing opening in relation to the axis of rotation of the ring bracket is secured against loosening from the cylinder core of the lock cylinder. The driver can be secured against removal in the radial direction from the lateral bearing opening by the connection to the lock cylinder and also against detachment from the cylinder core in the axial direction by the peripheral delimitation of the lateral bearing opening. This reliable and stable mounting of the driver in the insert part can be achieved with just two simple assembly steps, the lateral insertion of the driver into the lateral bearing opening and the axial insertion of the lock cylinder into the receiving opening of the insert part, so that the formed arrangement of insert part, driver and Lock cylinder can form an inherently stable assembly that can be flexibly supplied to the further assembly steps.

The invention also relates to a method for assembling a ring shackle padlock, which is designed as explained above and which has a ring shackle that can be rotated about an axis of rotation, a lock cylinder that has a rotatable cylinder core, a driver for driving the ring shackle, a single integral one-piece formed insert and a housing having a front housing part and a rear housing part comprises. The driver, the lock cylinder and the insert part are connected to one another in the axial direction with respect to the axis of rotation, and the insert part is inserted before or after this step of connecting along a lateral or radial direction through a peripheral cutout of the ring clip into an interior space of the ring clip. Then the resulting arrangement of insert, lock cylinder, driver and ring bracket is surrounded by the front housing part and the rear housing part, and the front housing part and the rear housing part are permanently connected to one another around the circumference.

With such an assembly method, the driver, the lock cylinder and the insert part can be connected exclusively from the axial direction and can therefore be carried out in a simplified manner. For example, the insert can first be inserted through a peripheral cutout of the ring bracket into its interior, with the insert being able to have guide sections, for example, against which the ring bracket bears in a non-positive manner after the insertion of the insert. With such a non-positive connection, a sufficiently stable connection can be produced between the insert part and the ring bracket, based on the requirements of the further assembly steps, so that the driver and the cylinder core then, in particular in a simple manual or automated manner, enter the insert part from the axial direction can be used while the insert part is held together with the ring bracket, for example.

Alternatively, it can also be provided to first connect the insert part to the driver and the cylinder core from the axial direction and then to insert the arrangement formed from it laterally through a peripheral cutout of the ring bracket into its interior.

In order to enable the driver to be inserted into the insert part from an axial direction and to be connected to the cylinder core, the insert part can have an assembly opening on a side facing the rear part of the housing. The connection of the insert part, lock cylinder and driver can, for example, take place in such a way that first the lock cylinder is inserted from the axial direction through the assembly opening into a receiving opening of the insert part provided for receiving the lock cylinder, whereupon the driver is inserted from the same direction through the assembly opening into a lateral clearance of the insert is used and connected to the lock cylinder. Alternatively, it can be provided that the lock cylinder is connected to the insert part from a side opposite the assembly opening and only the driver is inserted through the assembly opening, in which case the lock cylinder and the driver can be connected to the insert part simultaneously or in any order one after the other.

Again, the front housing part and the rear housing part can be welded to one another in the final step in order to achieve a permanent and stable connection of the two housing parts.

The driver can rest on the inside of the rear part of the housing and/or be secured by the rear part of the housing against loosening from the cylinder core in the axial direction. As a result, the driver can be securely supported in the axial direction and the driver can be prevented from becoming detached from the cylinder core, even if the driver is not held in the axial direction by the insert part itself, but rather this, for example, on one of the rear housing parts facing rear has a mounting hole to allow insertion of the driver from the axial direction.

In some embodiments, the driver can, as explained, have at least one sliding element with which the driver rests on the inside of the rear part of the housing.

In the above-mentioned embodiments of various assembly methods, the cylinder core can have a drive section and the driver can have a connection opening, whereby as a result of the connection of the lock cylinder and the driver, the drive section of the cylinder core can engage in the connection opening of the driver with a form fit, so that the driver can be held against a lateral or radial Loosening is secured from the cylinder core.

In some embodiments, the insert part can form a guide for the rotary movement of the ring bracket. The insert part can in particular have a plurality of guide sections, with at least one of the plurality of guide sections being assigned to a front peripheral section of the ring bracket and in particular bearing thereon, and at least one other of the plurality of guide sections being assigned to a rear peripheral section of the ring bracket and bearing in particular there. In particular, the respective guide sections can rest against the peripheral sections of the ring bracket in a non-positive manner, as a result of which a defined and clear guidance of the ring bracket can be achieved during the closing process. Furthermore, such a non-positive holding of the insert part in the interior of the ring bracket can be used to establish a stable connection between the insert part and the ring bracket, based on the requirements during assembly, so that the out of the insert part and the ring bracket formed arrangement in a simple manner fed to further assembly steps and while this can be moved, for example, without the connection between the insert part and the ring bracket unintentionally loosens.

The invention is explained in more detail below purely by way of example with reference to the drawings using two exemplary embodiments.

The embodiments of a ring shackle padlock 11 shown in the figures have a respective housing 35 which surrounds the other components of the ring shackle padlock 11 . This housing 35 is composed of a front housing part 37 and a rear housing part 39, which in the fully assembled state are firmly connected to one another along a parting plane and can be welded to one another, for example (cf. 8 ). The housing front part 37 can optionally have a rotatable keyhole cover with key insertion slot (not shown).

Within the housing 35, a ring bracket 13 is rotatably mounted about an axis of rotation A, which, as in FIG 1 shown, in a closed position, an indentation 41 formed on the housing 35 traverses, so that it is blocked in its mouth region. In this way, for example, two links of a chain (not shown) can be securely connected to one another, or a hasp can be closed by guiding the ring bracket 13 through its eyelet.

Furthermore, a respective insert part 43 is arranged inside the housing 35 of the ring shackle padlock 11, which is integrally formed in one piece (cf. also Figures 2a to 2c and Figures 9a to 9d ). The insert part 43 has a holding section 45 which is arranged approximately centrally between the ring bracket 13 and the indentation 41 and has a receiving opening 47 into which a lock cylinder 25 is inserted in a rotationally fixed manner. This lock cylinder 25, which can have a locking mechanism designed with pin or plate tumblers, for example, comprises a cylinder housing 27 and a cylinder core 29 rotatably mounted in the cylinder housing 27. By inserting a suitable key 55 (cf. 8 ) the tumblers of such a locking mechanism are sorted in the direction of the parting plane between the cylinder core 29 and the cylinder housing 27 in order to release the cylinder core 29 for a subsequent rotary movement.

In both shown embodiments of the ring shackle padlock 11, the insert part 43 has two pairs 53 of guide sections 51, which are arranged essentially diametrically opposite one another with respect to the axis of rotation A of the ring shackle 13 (cf. 1 and Figures 2a to 2c respectively. Figures 9a to 9d ). The guide sections 51 are wing-shaped and are designed as thin, tab-like structures at least in the area of the ring bracket 13, with the respective guide sections 51 of a pair 53 being offset axially in the direction of the axis of rotation A of the ring bracket 13, but aligned with one another and at least with one another in the axial direction are arranged essentially overlapping. The wing-shaped or tab-like design of the guide sections 51 enables interaction with the ring bracket 13 to guide it during a movement from the open position to the closed position or vice versa, and an axially flat design of the ring bracket padlock 11 (cf. 1 , 7a and 7b respectively. 13a and 13b ).

The distance between the guide sections 51 belonging to a pair 53 in the axial direction with respect to the axis of rotation A is selected in such a way that one guide section 51 of the respective pair 53 is on the front side 15 of the ring bracket 13 and the other guide section 51 of the pair 53 is on the back side 17 of the Ring bracket 13 rests (in each case on a radially inner region of the ring bracket 13). The respective peripheral section of the ring bracket 13, which is located in the region of a pair 53 of guide sections 51, can thereby be encompassed on both sides by the guide sections 51 and, in particular, can be guided in a force-fitting manner during a movement about the axis of rotation A (cf. 1 , 7a and 7b or 13a and 13b). Here, a substantially circular line takes place Contact between the guide portions 51 and the ring bracket 13 along a respective peripheral area.

Since the annular bracket 13 is encompassed on both sides by the pairs 53 of guide sections 51 in the axial direction, stable mounting and positioning of the annular bracket 13 in this direction can be achieved. Furthermore, a possible noise generation during the locking process and during transport of the ring bracket padlock 11 can be counteracted by such a guidance and the abutting of the ring bracket 13 on the guide sections 51 . Signs of wear, which are based on the ring bracket 13 hitting the housing 35 and in particular the indentation 41 during a movement of the ring bracket 13, can also be avoided by clearly guiding the ring bracket 13.

The guidance of the ring bracket 13 along several circumferential sections by the pairs 53 of guide sections 51 causes, in particular, a defined path of movement of the ring bracket 13 in a plane normal to its axis of rotation A, in order to prevent the ring bracket 13 from jamming during the closing process. In particular, this guide reliably prevents the ring bracket 13 from striking a boundary of an insertion opening 57 formed on the housing 35 , into which the ring bracket 13 is inserted after passing through the indentation 41 in order to block the indentation 41 . Due to the exact guidance of the ring bracket 13, the insertion opening 57 can also be designed with an advantageously small diameter and without major tolerances to the cross-sectional diameter of the ring bracket 13.

In principle, other arrangements of guide sections 51 than the one shown here are also possible, for example only a pair 53 of (in particular relatively large) guide sections 51 or an arrangement of three, four, five or more guide sections 51 may be provided alternately on the front side 15 and the back side 17 of the ring bracket 13 .

The insert part 43 can in particular be made from a material with a certain inherent elasticity, for example from a plastic. As a result, manufacturing and assembly tolerances can be compensated for, in particular with regard to the arrangement of ring bracket 13, lock cylinder 25 and housing 35 relative to one another. Because the guide sections 51 are elastic and can be deflected in a spring-back manner in the axial direction with respect to the axis of rotation A of the ring bracket 13 , the ring bracket 13 can be held and guided by the guide sections 51 in a non-positive manner. The cross-sectional diameter of the ring bracket 13, as shown in Figure 7a or in 13a shown, be greater than the distance in the axial direction of two overlapping guide sections 51 of a pair 53 in order to achieve a non-positive connection and reliable guidance.

That in the Figures 2a to 2c The shown insert part 43 of the first embodiment of the ring shackle padlock 11 also has a lateral clearance 59 which extends along part of the circumference of the insert part 43 . A driver 31 for driving the ring bracket 13 is inserted into this lateral clearance 59 and is mounted in the clearance 59 such that it can pivot with respect to the axis of rotation A of the ring bracket 13 . A part of the driver 31 protrudes laterally or in the radial direction from the opening 59 in order to be able to engage in the ring bracket 13, which is radially spaced apart from the lateral opening 59, and to be able to drive it (cf. 3 , 4a , 4b and 7b ).

For this purpose, the driver 31 engages with its free end in a drive recess 23 which is formed on the rear side 17 of the ring bracket 13 (cf. Figure 7b and also Figure 13b ). The driver 31 itself is coupled to the cylinder core 29, which has a drive section 30 at its rear end, the positively engages in a connection opening 33 of the driver 31 (cf. Figures 6a to 6c ). Such a form-fitting engagement means that the driver 31 is connected in a rotationally fixed manner to the cylinder core 29 and—if the lock cylinder 25 is held in the insert part 43—also secured against radial release from the lateral clearance 59 of the insert part 43 . Furthermore, this form-fitting engagement of the drive section 30 of the cylinder core 29 in the connection opening 33 of the driver 31 allows a rotation of the cylinder core 29 to be transmitted directly and without delay to the driver 31 and thus the ring bracket 13 .

The ring bracket 13 is coupled in a torque-proof manner to the lock cylinder 25 or the rotatable cylinder core 29 via the drive recess 23 and the driver 31, so that the ring bracket 13 can be moved either into the closed position or the open position by rotating the cylinder core 29 using the associated key 55 . In particular, the driver 31 can engage in the drive recess 23 of the ring bracket 13 essentially without play with respect to its pivoting direction, so that a rotation of the cylinder core 29 directly causes a movement of the ring bracket 13 . The closing process can thus take place without a time delay and noise during closing and any signs of wear due to the driver 31 hitting the boundaries of the drive recess 23 can be avoided. Furthermore, the driver 31 can be movably guided in the drive recess 23 in the radial direction in order to be able to compensate for an eccentricity of the axis of rotation of the cylinder core 29 or of the driver 31 relative to the axis of rotation A of the ring bracket 13 .

In the first embodiment of the ring bracket padlock 11 (cf. Figures 2a to 7b ) the insert part 43 forms a peripheral delimitation 61, 62 and 67 of the lateral clearance 59, so that this is designed as a slot-shaped bearing opening 49, through which the flat driver protrudes (cf. Figure 2c , 3 , 4a, 4b , 5a to 5c and 7b , also Figures 6a to 6c ). Limitations 61 and 62 act as stops that limit the pivoting movement of driver 31, so that clearly defined positions in the closed position and the open position can be specified for driver 31 in particular and accordingly also for ring bracket 13 driven by it, in that driver 31 in can rest against the respective limits 62 and 61 in these positions. In addition, the driver 31 is held in the axial direction in the lateral bearing opening 49 by the boundary 67 extending in the circumferential direction with respect to the axis of rotation A on a side facing the housing rear part 39 and is secured against loosening from the cylinder core 29 in this direction. Furthermore, the driver 31 is also securely connected to the drive section 30 of the cylinder core 29 in the radial direction by the positive engagement of the drive section 30 of the cylinder core 29 in the connection opening 33 of the driver 31 .

Regarding the insert part 43 (of both embodiments), it is inserted into the housing 35 in such a way that in the area of the indentation 41 formed by the front housing part 37 and the rear housing part 39 in the radial direction, it rests against the indentation 41 and in particular through respective supports 42 is secured against turning (cf. 3 and 10 ). This contact with the indentation 41 or the supports 42, which is effective in the direction of rotation, can ensure that the insert part 43 does not move in the direction of rotation as a result of a force applied to the ring bracket 13 in the event of an unauthorized attempt to open it, and the indentation 41 is reliably blocked by the ring bracket 13 remains blocked.

Since the ring bracket padlock 11 here consists exclusively of the ring bracket 13, the insert part 43, the locking cylinder 25, the driver 31, the housing front part 37 and the housing rear part 39, the ring bracket padlock 11 can be assembled easily. Optionally, also at the Front housing part 37 can be provided with a keyhole cover that is not formed in the embodiments shown, without this resulting in fundamental changes in the assembly of the ring bracket padlock 11 .

With regard to the assembly of the first embodiment of the ring shackle padlock 11, the first step is to insert the driver 31 from a lateral direction into the lateral bearing opening 49 of the insert part 43, so that the driver 31 is in the axial direction with respect to the axis of rotation A of the ring shackle 13 is held in the insert part 43 or in the lateral bearing opening 49 by the limitation 67 (cf. Figures 2a to 2c , 4a and 4b ).

The lock cylinder 25 can then be inserted into the receiving opening 47 provided on the holding section 45 of the insert part 43 from an axial direction with respect to the axis of rotation A of the ring bracket 13 on a front side of the insert part 43 facing the front part 37 of the housing (cf. Figure 2a and Figures 5a to 5c ). The lock cylinder 25 inserted into the receiving opening 37 can be frictionally connected thereto in order to enable stable and reliable mounting of the lock cylinder 25 in the center of the holding section 45 of the insert part 43 . Furthermore, the cylinder housing 27 can be fixed positively and non-rotatably in the insert part 43 as a result of being inserted into the receiving opening 47, so that only the cylinder core 29 of the lock cylinder 25 remains rotatable in order to open or close the ring bracket padlock 11 by actuating the locking mechanism enable. However, any unauthorized opening attempts aimed at moving the ring bracket 13 located in the closed position out of this position by rotating the cylinder housing 27 can be counteracted.

As the Figures 6a to 6c show, the driver 31 has the aforementioned connection opening 33, into which the drive section 30 of the cylinder core 29 engages in a form-fitting manner in order to direct a rotation transmitted by the key 55 to the cylinder core 29 to the driver 31 and through its engagement in the drive recess 23 to the ring bracket 13, so that the latter can be moved either into the closed position or into the open position (cf. also Figure 7b ). The form-fitting connection between the drive section 30 and the connection opening 33 can be produced in particular during assembly in the course of the axial insertion of the lock cylinder 25 into the receiving opening 47 of the holding section 45 .

As a result, even after this assembly step, the driver 31 is secured in the lateral bearing opening 49 by the limitation 67 both against detachment from the cylinder core 29 in the axial direction with respect to the axis of rotation A of the ring bracket 13 and by the drive section 30 of the cylinder core 30 against removal from the lateral bearing opening 49 secured in the radial direction. In addition to the secure mounting of the driver 31 within the housing 35, the arrangement formed can also be fed to the further steps for assembling the ring bracket padlock 11 as an inherently stable assembly.

After inserting the lock cylinder 25 into the receiving opening 47, the arrangement of the insert part 43, driver 31 and lock cylinder 25 is inserted into the interior space 21 of the ring bracket 13 and positioned there. The insert part 43 can be guided from a radial direction through the peripheral cutout 19 of the ring bracket 13, the central holding section 45 of the insert part 43, which is circular here in cross section, having an outer diameter that is smaller than the clear width of the peripheral cutout 19 of the ring bracket 13 ( see. Figures 7a and 7b ). In addition to a cylindrical configuration or one with a circular cross-section, other configurations of the holding section 45 are also possible, in which case the width of the holding section 45 or its extent in a plane normal to the axis of rotation A is less than in other Angular positions can be. In order to enable the insert part 43 to be inserted laterally into the interior space 21 through its peripheral cutout 19 in the manner described, it may in principle be sufficient if the minimum width of the holding section 45 or its width in at least one angular position is less than the clear width of the Scope section 19 is.

The insert part 43 and in particular the guide sections 51 arranged in two pairs 53 can be designed to be elastic and resiliently deflectable in particular in the axial direction in order to simplify the introduction of the insert part 43 into the interior 21 of the ring bracket 13 through its peripheral cutout 19 . In particular, the guide sections 51 of a respective pair 53 can be temporarily bent apart during insertion of the insert part 43 in order to increase their distance from one another in the axial direction. As a result, the ring bracket 13 or its ends adjoining the peripheral cutout 19 can be guided between the two guide sections 51 of a pair 53 during the insertion of the insert part 43 into the interior space 21 of the ring bracket 13, which have a larger circumferential extent than the peripheral cutout 19 of the Have ring bracket 13 and can block insertion of the insert part 43 without such an axial deflection.

As soon as the insert part 43 has been fully inserted into the interior space 21 of the ring bracket 13, the guide sections 51 can spring back in the axial direction, so that the ring bracket 13 in the area of the pairs 53 of guide sections 51 has a non-positive fit with its front side 15 and its rear side 17 on a respective guide section 51 may be present. This non-positive holding of the ring bracket 13 by the guide sections 51 can create a stable connection between the insert part 43 and the locking cylinder 25 arranged therein and the driver 31 on the one hand and the ring bracket 13 on the other hand with regard to the requirements for the assembly of the ring bracket lock 11, so that this arrangement further assembly steps without the risk of an unexpected Solving the components can be supplied from each other. Furthermore, the ring bracket 13 can be guided safely and in a defined manner by the guide sections 51 during a rotation about the axis of rotation A in the course of a later closing process and can be held stably by them in the axial direction.

In a final assembly step, the front housing part 37 and the rear housing part 39 of the housing 35, which are designed here as respective half-shells, are firmly connected to one another along a parting plane, which can be done, for example, by welding. 8 shows a front view of the fully assembled ring shackle padlock 11 in the closed position of the ring shackle 13. The ring shackle 13 traverses the indentation 41 formed by the housing 35 in the radial direction, so that the ring shackle padlock 11 can be connected, for example, to an object not shown.

The other components of the ring bracket padlock 11 are covered by the housing 35 or surrounded by it, so that unauthorized access to them can be prevented. Only the cylinder core 29 of the lock cylinder 25 remains accessible in an approximately central recess in the front part of the housing 37 in order to be able to unlock the ring shackle padlock 11 using the key 55 and then turn the cylinder core 29 so that the ring shackle 13 can be moved from the closed position to the the open position or vice versa can be transferred.

In particular, the formation of the ring shackle padlock 11 of this first embodiment with only a minimal number of parts and the integrally one-piece formed insert part 43 enables simplified assembly compared to conventional ring shackle padlocks, since only a few easy-to-perform steps are required. Furthermore, all steps are carried out from the axial or from the radial direction with respect to the axis of rotation A of the Ring bracket 13, so that this can be done by clearly specifiable movements and, if necessary, at least some of the assembly steps can also be automated.

the Figures 9a to 9d show an insert part 43 of a second embodiment of the ring shackle padlock 11, which is also integrally formed in one piece and has two pairs 53 of respective aligned, tab-like guide sections 51. Again, the ring bracket 13 can be held in a non-positive manner by these opposite pairs 53 of guide sections 51 with respect to the circumferential direction of the ring bracket 13 and can be guided during a movement from the closed position to the open position or vice versa, so that uniform and reliable guidance can be achieved (cf. also 1 , 13a and 13b ). In this regard, to the extent similar to the first embodiment according to Figures 2 to 8 referred.

Furthermore, this insert part 43 is also designed with an approximately centrally arranged retaining section 45 and a receiving opening 47 for the lock cylinder 25, into which the lock cylinder 25 can be inserted from an axial direction with respect to the axis of rotation A of the ring bracket 13, so that the cylinder housing 27 is frictionally engaged and non-rotatable is held in the receiving opening 47 (cf. also 10 and 11a ).

Likewise, the insert 43 has a lateral clearance 59 into which a driver 31 is or can be inserted and from which the inserted driver 31 protrudes in the radial direction with respect to the axis of rotation A of the ring bracket 13, around the radially to the holding section 45 of the insert 43 spaced ring bracket 13 to be able to drive (see also 10 , 11a to 11e , 12a to 12c , 13a and 13b ). For this purpose, the driver 31 is mounted pivotably in the lateral clearance 59 of the insert part 43 and engages in a space provided for this purpose the back of the ring bracket 13 formed drive recess 23 of the ring bracket 13 (see also Figure 13b ).

Here, too, the movement of the driver 31 in the circumferential direction is restricted by two limitations 61 and 62 which are formed by the insert part 43 . These limitations 61 and 62, which act in the sense of respective stops, can be used to position the driver 31 and accordingly also the ring bracket 13 in the closed position and the open position in a targeted and predetermined manner by the driver 31 being in the closed position on the limitation 62 and in the open position rests against the limit 61 (cf. also Figure 9b , 9d , 11a to 11e and 13b ). The limitation 62 can also counteract any attempts to push the ring bracket 13 beyond the closed position, for example, and thereby open the ring bracket padlock 11 .

Limitations 61 and 62, which act as a stop for a pivoting movement of driver 31, are connected to one another by a hollow cylinder section 65, on whose inner lateral surface 63 the part of driver 31 that does not protrude from lateral clearance 59 can be guided during a pivoting movement (cf. Figure 9b , 9d , 11c , 11d and 13b ). This inner lateral surface 63 extends over an angular range of approximately 180° and, in addition to guiding the driver 31 during a pivoting movement, can also serve in particular to absorb any forces acting from the radial direction with respect to the axis of rotation A on the ring bracket 13 or the driver 31, at least derive partially on the insert 43. Possible damage to the ring bracket padlock 11 or the locking cylinder 25 connected to the driver 31 and removal of the driver 31 from the ring bracket 13 can be prevented in this way.

Basically, the insert 43 can also be in the Figures 2a to 7b shown first embodiment form such an inner lateral surface 63 of a hollow cylinder section 65 on a side radially opposite the lateral bearing opening 49 on which the driver 31 is guided during a pivoting movement (angular range of maximum 180°).

In contrast to the one in the Figures 2a to 7b illustrated first embodiment forms the in the Figures 9a to 9d The shown insert part 42 of the second embodiment of the ring shackle padlock 11 has no peripheral delimitation of the lateral clearance 59 and in particular has no delimitation 67 on the rear side of the insert part 42 facing the rear part 39 of the housing (cf Figure 2c , 4a , 4b and 5a to 5c of the first embodiment). Rather, the lateral clearance 59 delimited by the inner surface 63 of the hollow cylinder section 65 is accessible from the axial direction in relation to the axis of rotation A of the ring bracket 13 through an assembly opening 69, so that the driver 31 can be inserted through this assembly opening 69 from the axial direction into the lateral clearance 59 (see. Figures 9b to 9d , 11a to 11e and 13b ). This can allow for another way of mounting the ring bail padlock 11, as will be explained below.

As the Figures 12a to 12c show, the cylinder core 29 of the lock cylinder 25 of this embodiment in turn has a drive section 30 which positively engages in a connection opening 33 of the driver 31 . This form-fitting engagement of the drive section 30 of the cylinder core 29 in the connection opening 33 of the driver 31 allows a rotational movement transmitted to the cylinder core 29 by means of the key 55 to be transmitted directly and without delay to the driver 31 for driving the ring bracket 13. Since the driver 31 can also positively engage in the drive recess 23 of the ring bracket 13 with respect to the circumferential direction, a smooth and smooth closing process can be achieved (cf. also figure 13b ). This connection to the drive section 30 also secures the driver 31 against lateral release or release in the radial direction with respect to the axis of rotation A from the cylinder core 29 and from the lateral clearance 59 when the lock cylinder 25 is inserted into the receiving opening 47 of the insert part 45 used and connected to the driver 31.

In order to also secure the driver 31 against loosening from the cylinder core 29 in the axial direction with respect to the axis of rotation A of the ring bracket 13, the side of the driver 31 facing away from the cylinder core 29 can bear against an inner side of the housing rear part 39 (cf. 10 ). For this purpose, the driver 31 is less flat in the axial direction with respect to the axis of rotation A than the driver 31 of the first embodiment in the area in which the driver 31 is inserted into the assembly opening 69 and is designed with an axial extension which is approximately the height corresponds to the inner lateral surface 63 of the hollow cylinder section 65 (cf. for the design of the respective driver 31 in particular Figure 6b and Figure 12b ). This driver 31, which is of less flat design, can thus be connected both to the drive section 30 of the cylinder core 29 and to the inside of the housing rear part 39 (cf. Figures 11a to 11e and 13b ), while the flat driver 31 is provided for a precise fit in the lateral bearing opening 49 (cf. Figures 4a, 4b and 5a to 5c ).

In order to enable the driver 31 to be guided as smoothly as possible during a movement along the inside of the housing rear part 39 for driving the ring bracket 13, the driver 31 has five sliding elements 71 on the side facing the housing rear part 39 in the area that does not protrude from the lateral opening 59 , which are designed as elevations extending from the surface of the driver 31 in this area (cf. 11c , 11d , 12b , 12c and 13b ). These sliding elements 71, which can be designed, for example, in the form of pins, cones, truncated cones, spheres or hemispheres, the friction between the driver 31 and the inside of the housing rear part 39 can be reduced during a movement of the driver 31 in order to achieve smooth guidance of the ring bracket 13. The sliding elements 71 are arranged along a ring around the axis about which the driver 31 pivots during a movement, so that the driver 31 can be supported evenly.

In principle, the design of the driver 31 with sliding elements 71, which in particular can also be provided in a different way, in a different number or in a different arrangement, is not limited to this second embodiment of the ring bracket padlock 11. Rather, the driver 31 of the first in the Figures 2a to 7b illustrated embodiment of the ring bracket padlock 11 with such sliding elements 71 in order to reduce the friction between the driver 31 and the inside of the insert part 43, on which the driver 31 rests during a movement, and to enable a smooth pivoting movement.

Due to the fact that the insert part 43 is designed differently from the insert part 43 of the first embodiment of the ring bracket padlock 11 and has an axial assembly opening 69, there is also the possibility of a modified assembly method.

In a first step, the insert part 43, the lock cylinder 25 and the driver 31 can be connected to one another from the axial direction. For example, the lock cylinder 25 can first be inserted through the assembly opening 69 into the receiving opening 47 of the holding section 45 of the insert part 43, whereupon the driver 31 can also be connected to the cylinder core 29 through the assembly opening 69. In particular, the insert part 43 can be held fixed during the connection to the lock cylinder 25 and the driver 31, so that only movements from a single axial direction are required by guiding both the lock cylinder 25 and the driver 31 through the assembly opening 69 during insertion. In principle, these clearly defined and simple movements from one direction can also make it possible to carry out this assembly step automatically.

Provision can also be made for locking cylinder 25 and driver 31 to be inserted into insert part 43 from different axial directions and, for example, simultaneously or one after the other, so that, for example, only driver 31 can be inserted through assembly opening 69, while locking cylinder 25 can be inserted from the axially opposite direction Front of the insert part 43 is inserted into the receiving opening 47.

Irrespective of the order in which the insert part 43, the lock cylinder 25 and the driver 31 are connected to one another, the drive section 30 of the cylinder core 29 can positively engage in the connection opening 33 of the driver 31 as a result of this axial connection of the named parts, so that the driver 31 is secured against lateral detachment from the cylinder core 29 (cf. also Figures 12a to 12c ). Furthermore, the lock cylinder 25 or the cylinder housing 27 can be held in the receiving opening 47 of the holding section 45 of the insert part 43, for example by friction, so that a stable connection of the insert part 43 and the lock cylinder 25 is achieved and the arrangement of insert part 43, lock cylinder 25 and driver 31 in particular in an orientation in which a gravitational detachment of the driver 31 from the cylinder core 29 is avoided, the further steps for the assembly of the ring bracket padlock 11 can be supplied flexibly.

For example, in a subsequent step, the arrangement of insert part 43, driver 31 and locking cylinder 25 can be guided from a lateral direction through the circumferential cutout 19 of the ring bracket 13 into its interior 21, for which purpose the holding section 45, which is circular in cross section, again has a has a smaller outer diameter than the clear width of the peripheral cutout 19. The elastic and resilient guide sections 53 can be bent apart during insertion into the interior 21 of the ring bracket 13 in order to facilitate the connection of the insert part 43 to the ring bracket 13.

Equally, it can also be provided—in reverse order—to guide the insert part 43 through the peripheral cutout 19 of the ring bracket 13 into its interior space 21 and to arrange it there in a first step of the assembly. The lock cylinder 25 and the driver 31 can then be connected to the insert part 43 arranged in the interior space 21 of the ring bracket 13 from the axial direction, as described above. In particular, a non-positive connection between the pairs 53 of guide sections 51 and the ring bracket 13 can form a stable arrangement of the insert part 43 and the ring bracket 13, which enables simple subsequent insertion of the lock cylinder 25 and the driver 31 into the insert part 43. without the need for special care to prevent the ring bracket 13 from becoming detached from the insert part 43 during this process.

At the end of the assembly process, the already assembled components consisting of the insert part 43, the locking cylinder 25, the driver 31 and the ring bracket 13 can be inserted into the housing 35 and the front part 37 of the housing can be firmly connected to the rear part 39 of the housing. This assembly can also take place in particular from the axial direction and, if necessary, in an automated manner, in which case the rear housing part 39, on which the driver 31 rests with the sliding elements 71 in the assembled state, can be guided, in particular from above, in order to prevent the driver 31 from detaching from the cylinder core 29 due to gravity to prevent in reverse arrangement. Again, the assembled housing 35 surrounds the components located within it and only the Cylinder core 29 remains accessible from the outside in order to be able to be turned using the key 55 (cf. 8 ).

Due to the small number of components, this assembly method can also be carried out more quickly and easily than conventional methods, in particular, apart from the lateral introduction of the insert part 43 into the interior 21 of the ring bracket 13, exclusively axial movements with respect to the axis of rotation A of the ring bracket are required for all steps 13 are necessary. These simple, clearly defined assembly steps, which are to be carried out in a straight line, can in principle also enable automated or at least partially automated assembly of the ring bracket padlock 11 .
