Description

The present invention relates to a padlock comprising a lock body and a hoop which is held displaceably at the lock body and which has a first and a second shank. The padlock furthermore has a rotational bolt, which is rotatable about an axis of rotation at least between a release position and a latching position, and at least one blocking element. The lock body comprises a first and a second reception passage for receiving the first and second shanks of the hoop respectively as well as a reception opening for replaceably receiving a lock cylinder which is shaped asymmetrically in cross-section, with a cylinder housing of the lock cylinder merging into an elongate flange section starting from a circular cross-section of a core reception section, said lock cylinder having a rotatable closing nose which is or can be drive-effectively coupled to the rotational bolt. The rotational bolt comprises at least one drive section which, in the latching position of the rotational bolt, is adapted to urge the blocking element radially outwardly with respect to the axis of rotation in the direction of a blocking recess of the first shank.

With such a padlock, the lock cylinder is actuated by a matching key for unlocking. A cylinder core of the lock cylinder is thereby rotated whose rotational movement is transferred to the rotational bolt via the closing nose. The closing nose of a lock cylinder is a rotational drive element eccentric with respect to the axis of rotation. The closing nose can be fastened at a variable angle position to the cylinder core of the lock cylinder. In the assembled state of the lock cylinder, the closing nose is, however, rotationally fixedly connected to the cylinder core.

In the release position of the rotational bolt, the hoop of the padlock can be opened, i.e. at least one shank of the hoop can be removed from the associated reception passage of the lock body. In the latching position of the rotational bolt, in contrast, both shanks of the hoop are fixed in the associated reception passages of the lock body.

It is desired for some applications that the lock cylinder of the padlock can be replaced by the user. The padlock can be integrated in a simple manner into already existing locking systems, for example, due to the replaceability of the lock cylinder. A lock cylinder can thus be installed into the padlock with a locking mechanism associated with the locking system, whereby a key of the locking system can also be used for the padlock and thus a wide range of uses results for the padlock. The padlock can in this respect selectively be equipped with a plurality of different lock cylinders - for example also from different manufacturers. The padlock can also be offered without its own lock cylinder for this purpose, i.e. for retrofitting by the user with the user's own lock cylinder.

The lock cylinders used in such a padlock are typically standardized. This means that the padlock has to be dimensioned at least with respect to the size of the associated reception opening such that it can receive the lock cylinder. In addition, it is possible to combine a conventional latching mechanism of a padlock with a replaceable lock cylinder. Known such padlocks are, however, undesirably large and/or material intensive and labor intensive in manufacture. A padlock in accordance with the preamble of claim 1 is known from GB 2 424 670 A. US 2,141,748 and EP 0 971 087 A1 describe padlocks in which the hoop can be locked twice. EP 1 460 212 A2 discloses a padlock into which a standard half-lock cylinder in accordance with DIN 18252 can be inserted. Finally, a padlock comprising a replaceable standard half-lock cylinder in accordance with DIN 18252 is known from WO 2006/032416 Al.

It is an object of the invention to provide a padlock which is characterized by compact dimensions, an inexpensive manufacture and a high security against unauthorized opening.

This object is satisfied by a padlock having the features of claim 1 and in particular in that the rotational bolt furthermore comprises a blocking section which, in the latching position of the rotational bolt, is adapted to engage into an associated blocking recess of the second shank in a tangential direction with respect to the axis of rotation.

The hoop is therefore secured in the lock body in the latching position of the rotational bolt by two different latching methods, namely on the one hand, by the (at least one) blocking element urged radially outwardly in the direction of the blocking recess of the first shank. On the other hand, a blocking section of the rotational bolt is brought in the tangential direction, i.e. along the direction of rotation of the rotational bolt, into engagement with the blocking recess of the second shank of the hoop. The anyway necessary rotation of the rotational bolt is thus advantageously used for the additional latching of the hoop, whereby a double latching is achieved (i.e. a latching of both hoop shanks). In addition, a customary second blocking element can be saved in this respect.

In addition, an off-center arrangement of the axis of rotation of the rotational bolt and/or an off-center arrangement of the axis of rotation of the cylinder core of the lock cylinder in the lock body is/are possible by the use of the blocking section of the rotational bolt (in particular when the rotational bolt engages directly into the blocking recess of the second hoop shank via the blocking section). The axis of rotation of the rotational bolt and/or of the cylinder core can be arranged close to the second shank of the hoop, that is close to an axis of the corresponding reception passage of the lock body, whereby the lock cylinder can be better accommodated in the lock body and the dimensions of the lock body can thus be reduced.

The lock body can therefore in particular be configured as smaller because the lock cylinder respectively only has to observe a minimal spacing from the axes of the reception passages and thus from the shanks of the hoop. In comparison with an axis of rotation of the rotational bolt and/or of the cylinder core arranged centrally between the reception passages, unused space in the lock body is thus omitted, whereby the padlock in accordance with the invention can be configured more compactly.

The customary appearance of a usual padlock advantageously results for the end consumer due to the compact design of the padlock in accordance with the invention since the lock body (i.e. the lock housing) can be designed as comparatively slim and the key introduction opening can as usual be arranged at the lower side of the lock body.

In accordance with the slim construction shape, a reduced material effort results for the lock body which is accompanied by low manufacturing costs.

The manufacturing process of the padlock can therefore also be configured inexpensively since only the introduction of bores (i.e. of straight-line holes of constant diameter) is required for generating the reception passages for the hoop shanks and for generating the reception opening for the lock cylinder and undercuts (i.e. lateral recesses in the bores) with the necessity of using special tools being able to be avoided.

In addition, the padlock is particularly well protected against an unauthorized opening (e.g. forced pulling of the hoop out of the lock body, manipulation of the latching mechanism) by the use of two different latching methods and directions of the latching of the two hoop shanks. For example, a method for the forced radial urging back of the blocking element is not necessarily also suitable for overcoming the tangentially guided blocking section of the rotational bolt.

The blocking section of the rotational bolt can advantageously engage directly into the blocking recess of the second hoop shank. In this way, no mechanical unit interposed between the rotational bolt and the blocking section is required which would in turn increase the size of the padlock.

To actuate the blocking element, the drive section forms a cam track, which differs from a circular path, for displacing the blocking element. The blocking element can be moved radially outwardly on the rotation of the rotational bolt due to the cam track and can thus engage into the blocking recess of the first shank. On an attempt to remove the hoop from the lock body in the latching position, the blocking element can thus be wedged in the blocking recess. At the same time, the blocking section of the rotational bolt contacts the associated blocking recess areally, whereby the blocking element and the blocking section at both shanks prevent the removal of the hoop. The stability of the latching mechanism is in particular increased in comparison with a use of thin bolt plates due to the combination of the blocking element and the blocking section.

The padlock in accordance with the invention is particularly well suited for a replaceable reception of commercial lock cylinders having a rotatable closing nose which is drive-effectively coupled to the rotational bolt of the padlock. In particular a commercial halfcylinder can be used as the lock cylinder since the lock cylinder is anyway only accessible from one side on use in a padlock. For example, without the necessity of mechanical adaptations, commercial profile cylinders can be used which are standardized in accordance with DIN 18252 and whose cylinder housings have a core reception section and a flange section.

The introduction of the lock cylinder into the associated reception opening of the lock body in this respect takes place from the side of the lock body remote from the hoop, i.e. from the lower side in the position of use of the padlock. Generally, the region of the hoop is called the upper side and the region remote from the hoop is called the lower side of the padlock.

The rotational bolt can in particular be arranged within the reception opening for the lock cylinder such that the rotational bolt forms an abutment for the lock cylinder on the introduction of the lock cylinder into the lock body and the rotational bolt is thus captured in an axial direction between the boundary of the reception opening at the upper side and the lock cylinder (and/or an adapter piece such as will be explained in the following). A simple replacement of the lock cylinder is possible by this arrangement of the rotational bolt at the longitudinal end of the lock cylinder since said lock cylinder can be removed or inserted at the lower side of the lock body. On the insertion and removal, the rotational bolt and the blocking element can remain in the lock body.

Advantageous embodiments of the invention are described in the description, in the dependent claims and in the drawings.

In accordance with an advantageous embodiment, the axis of rotation of the rotational bolt and/or the axis of rotation of the closing nose (or of the cylinder core) of the lock cylinder received in the reception opening is/are arranged off-center with respect to the first and second reception passages of the lock body (for the two hoop shanks), i.e. the respective axis of rotation is not arranged exactly at the center between the two reception passages. The axis of rotation of the rotational bolt can thus be disposed closer to the second shank of the hoop, whereby the radius of the rotational bolt can be reduced. The padlock can in turn be configured as more space saving and material saving due to the smaller rotational bolt. If the axis of rotation of the closing nose or of the cylinder core of the lock cylinder is disposed closer to the second shank of the hoop, the lock cylinder can be better accommodated in the lock body.

In accordance with a further advantageous embodiment, the axis of rotation of the rotational bolt coincides with the axis of rotation of the closing nose (or of the cylinder core) of the lock cylinder received in the reception opening. In this manner, the closing nose can be coupled to the rotational bolt, e.g. by a direct form-fitted connection, without any complex mechanical unit on the introduction of the lock cylinder. As a result, both the rotational bolt and the lock cylinder (cylinder core) are disposed off-center and thus particularly close to the second shank, whereby an unnecessary space consumption is avoided.

In accordance with a preferred embodiment, the drive section and the blocking section are formed integrally at the rotational bolt. The drive section and the blocking section can therefore in particular be configured in one piece with the rotational bolt, whereby a rotational movement of the rotational bolt is always transferred both to the blocking element and to the blocking section and the rotational bolt can engage via the blocking section directly into the associated blocking recess of the second hoop shank. In this manner, a secure and uniform latching of the padlock is ensured by means of the blocking element moved synchronously with the blocking section.

Alternatively to this, the blocking section can, however, generally also be configured as a separate part which is connected to the rotational bolt rigidly or with rotational clearance. For example, the blocking section can be manufactured from hardened metal, whereas the rotational bolt can be formed from another material (e.g. plastic) for saving weight.

In accordance with a further advantageous embodiment, the blocking element is elongate. Such an elongate extent of the blocking element can in particular be provided along the direction of the latching movement of the blocking element (i.e. in a radial direction with respect to the axis of rotation of the rotational bolt). The spacing between the drive section of the rotational bolt and the blocking recess of the first shank caused by the off-center arrangement of the axis of rotation of the rotational bolt is bridged by the elongate design of the blocking element.

The blocking element advantageously has at least one rounded, preferably circular, end.

On an attempt of a forced removal of the hoop from the lock body, the circular end is thus wedged with the blocking recess of the first hoop shank, with a favorable force distribution over an enlarged surface of the blocking element and of the blocking recess resulting due to the circular design. The circular or rounded end thus makes shearing off of the end of the blocking element more difficult. In this manner, the force required to break open the padlock is greatly increased.

The shape of the elongate blocking element can in particular be formed by two semispheres which are connected via a cylindrical connection section.

Alternatively, at least two blocking spheres can be provided as a blocking element and are arranged behind one another, with the force of the drive section of the rotational bolt being transmitted from the first blocking sphere to the second blocking sphere.

In accordance with a preferred embodiment, the blocking element and the blocking section of the rotational bolt are arranged offset relative to one another with respect to the axis of rotation of the rotational bolt. The blocking element and the blocking section can therefore be arranged at different tiers (i.e. levels) viewed along the axis of rotation. If, for example, the blocking section of the rotational bolt (and thus the associated blocking recess of the second shank of the hoop when it is fully introduced into the lock body) is further downward in the lock body, only the blocking recess of the first shank can thus be removed from the lock body on the opening of the hoop (in the release position of the rotational bolt), whereas the blocking recess of the second shank remains within the lock body.

The rotational bolt advantageously comprises a first and a second tier which are each formed substantially in disk shape and which are arranged above one another along the axis of rotation of the rotational bolt. The rotational bolt can thus be built up in the manner of a tower, with the centers of the disks each lying on the axis of rotation of the rotational bolt. Each of the named tiers can in particular extend perpendicular to the axis of rotation of the rotational bolt.

The first tier preferably comprises the drive section and the second tier comprises the blocking section of the rotational bolt. Due to the arrangement of the blocking section and the drive section on different tiers, they can be disposed offset relative to one another with respect to the axis of rotation. In addition, the mechanical load on the rotational bolt can be distributed over different tiers.

The second tier can also comprise, in addition to the blocking section, a release section and optionally furthermore an assembly section. In the region of the release section, the second tier of the rotational bolt can have a smaller radius than in the region of the blocking section, with the release section of the rotational bolt being able to be brought into the region of the second shank by a rotation of the rotational bolt into the release position. There is thereby no engagement of the release section into the blocking recess of the second shank and the hoop can be partly removed from the lock body until, for example, a securing section of the hoop areally contacts the release section and thus prevents a complete removal of the hoop from the lock body.

If the rotational bolt is rotated even further into an assembly position, the assembly section of the rotational bolt can be brought into the region of the second hoop shank, with the radius of the second tier again being smaller in the region of the assembly section than in the region of the release section. As a result, the securing section of the hoop can be moved past the assembly section and the hoop can be completely removed from the lock body.

The hoop can likewise be introduced into the lock body in this assembly position of the rotational bolt on the manufacture of the padlock.

In accordance with a preferred embodiment, the rotational bolt comprises a third tier between the first and the second tiers, the rotational bolt being able to be supported at the lock cylinder in the radial and/or axial direction in said third tier. In this respect, the first and third tiers can be designed as hollow and can each be provided with a peripheral cutout. The flange section of the lock cylinder can, for example, project out of the peripheral cut-out. At the same time, the rotational bolt can form an abutment for the lock cylinder in the axial direction.

The named lock cylinder does not necessarily have to be a component of the padlock, namely if the padlock is provided to be retrofitted with a commercial lock cylinder (e.g. an existing locking system). In accordance with a preferred embodiment, the lock cylinder is, however, a component of the padlock. In this embodiment, the lock cylinder can comprise a cylinder core which is rotatably supported in a cylinder housing and to which the named closing nose is rotationally fixedly connected.

The closing nose of the lock cylinder preferably projects into a cut-out of the rotational bolt, with a rotational clearance preferably being present between the closing nose and the rotational bolt. The closing nose can in particular project into the named peripheral cut-out of the second tier and can come into contact with the sidewalls of the cut-out on a rotational movement of the closing nose to transmit a rotational movement of the closing nose to the rotational bolt. In other words, the two lateral boundaries of the peripheral cutout serve as abutment edges. Due to the rotational clearance, the closing nose of the lock cylinder can be more easily introduced into the peripheral cut-out of the rotational bolt and/or can be brought into a flush angular position with the lock cylinder on the insertion of the lock cylinder into the lock body in order to be able to insert the lock cylinder into the lock body or remove it from the lock body.

An adapter piece is preferably arranged in the reception opening of the lock body between the lock cylinder and the lock body and forms a rotational abutment for the closing nose of the lock cylinder in the release position and/or in the latching position of the rotational bolt. A rotation of the rotational bolt into an unwanted position can thus be prevented by the adapter piece. At the same time, the adapter piece can at least regionally adapt the contour of the reception opening of the lock body to the contour of the lock cylinder and the adapter piece can furthermore hold the rotational bolt and the blocking element within the reception opening of the lock body. The adapter piece can, for example, be fastened in the reception opening of the lock body by means of a pin or a screw or by a press fit. The adapter piece is preferably permanently fastened in the lock body. Alternatively to this, however, a releasable fastening in the lock body can be provided, whereby the padlock can be adapted to different lock cylinders by replacing the adapter piece.

In accordance with a further advantageous embodiment, the reception passages of the lock body (for the two hoop shanks) extend in parallel with the axis of rotation of the rotational bolt. The lock cylinder can thereby be introduced into the padlock from the lower side thereof, whereby the customary design for a user of the padlock results with a key introduction opening arranged at the lower side of the housing.

In accordance with a further advantageous embodiment, a passage bore for a cylinder fixing screw is provided in the lock body and the lock cylinder can be secured in the reception opening of the lock body by means of said cylinder fixing screw. The lock cylinder is thus additionally secured by the cylinder fixing screw against a pulling out of the lock body.

The lock cylinder is preferably a profile cylinder standardized in accordance with DIN 18252 which comprises a cylinder housing with a hollow cylindrical core reception section for a rotatable support of the cylinder core and a flange section which projects radially away from the core reception section and in which pin tumblers can be provided. The lock cylinder is thus shaped asymmetrically (i.e. not circularly) in cross-section in accordance with the invention, with the cylinder housing merging into an elongate flange section from a circular cross-section of the core reception section. When the cylinder housing is inserted into the padlock (i.e. into the associated reception opening of the lock body), the core reception section of the cylinder housing can come to lie closer to the axis of the second reception passage of the lock body (for the second shank of the hoop), with the flange section of the cylinder housing extending from the core reception section in the direction of the axis of the first reception passage (for the first shank).

It is in particular possible due to the embodiment of the rotational bolt in accordance with the invention that a plane of symmetry of the lock cylinder (in particular the plane of symmetry of a profile cylinder which extends along the axis of rotation of the cylinder core through the core reception section and the flange section) coincides with or extends in parallel with the center plane of the lock body which is spanned by the axes of the two reception passages of the lock body for the hoop shanks. For this purpose, a plane of symmetry of the named reception opening of the lock body can in particular coincide with or extend in parallel with the center plane of the lock body. The customary appearance of a usual padlock can thus be realized for the end consumer with which the keyway of the lock cylinder (i.e. the slot-shaped key introduction opening of the cylinder core) extends along the center plane of the lock body or in parallel therewith.

The invention will be explained in the following only by way of example with reference to the drawings. Elements which are the same or of the same kind are marked by the same reference numerals therein.

There are shown:

Fig. 3 a rotational bolt in (a) a perspective view from below and (b) a view from above;

Fig. 5 an adapter piece in a perspective view; and

Fig. 6 the padlock of Fig. 1 in the assembled state without a lock body in (a) a first perspective side view and (b) a second perspective side view.

The padlock 10 shown in Fig. 1 comprises a lock body 12 and a hoop 14. The hoop 14 is formed in U shape from a cylindrical material and comprises a first shank 16 and a second shank 18. The shanks 16, 18 are each straight.

The padlock 10 can be moved from a latched state into an unlatched state and vice versa by means of a key 20. The key 20 can in this respect be introduced into a key introduction opening at a lower side of the lock body 12 which is opposite the hoop 14.

The padlock 10 of Fig. 1 is shown in an exploded view in Fig. 2. A first blocking recess 22 is provided in the hoop 14 in its first shank 16 and is arranged at a lower end of the first shank 16 and is of cylinder segment shape or circular segment shape.

The hoop 14 is formed throughout from a substantially circular cross-section.

The second shank 18 is longer than the first shank 16 and comprises in a region disposed beneath the end of the first shank 16 a second blocking recess 24 which is formed by removal of a parallelepiped-shaped region. A release recess 26 adjoins the second blocking recess 24 from below and is formed by a concave recess of the second shank 18 facing the first shank 16. A rotational section 28 adjoins beneath the release recess 26 and has a circular cross-section which is reduced in size with respect to the usual cross-section of the hoop 14, i.e. the rotational section 28 forms an annular groove. A securing section 30 with a round cross-section which corresponds to the usual cross-section of the hoop 14 forms the end of the second shank 18.

In the latched state of the padlock 10, the first shank 16 extends into a first reception passage 32 and the second shank 18 extends into a second reception passage 34 of the lock body 12. The reception passages 32, 34 can be recognized as upper side openings outside the lock body 12. The reception passages 32, 34 are adapted to the cross-section of the hoop 14.

The lock body 12 is shown in more detail in Fig. 4. The lock body 12 has a substantially rectangular cross-section, with the longitudinal sides being outwardly arched. A reception opening 36 is introduced into the lock body 12 from below. The reception opening 36 tapers step-wise toward the top. A passage bore 38 for a cylinder fixing screw is provided at a side surface. A rotational bolt 40 (Fig. 2) is inserted into the reception opening 36 and is in direct contact with a blocking element 42. The blocking element 42 has an elongate shape which is formed by two semi-spherical sections 44 and a cylindrical section 46 connecting the semi-spherical sections 44.

The rotational bolt 40 is built up of three tiers like a tower (Fig. 3a). In the installed state, a first tier 48 faces the U-shaped region of the hoop 14 and thus lies at the top. A second tier 50 forms the lower end of the rotational bolt 40. A third tier 52 is arranged between the first and second tiers 48, 50.

All the tiers 48, 50, 52 have an outer surface of substantially cylinder jacket shape - apart from peripheral cut-outs and/or recesses - with the radius of the tiers increasing from the top to the bottom. This means that the radius of the first tier 48 is smaller than that of the third tier 52. The radius of the third tier 52 is in turn smaller than that of the second tier 50 (Fig. 3b). A cylindrical depression which serves together with the peripherally adjacent region as a drive section 54 is introduced into the first tier 48, i.e. into the upper tier.

The third tier 52, i.e. the middle tier, is hollow cylindrical, with a jacket surface being cut open in an angular region of approximately 70°. This cut-out 55 is bounded by two abutment surfaces 56a, 56b.

The second tier 50, i.e. the lower tier, comprises a cut-out 57 of its jacket surface of approximately 20°, with drive surfaces 58a, 58b defining the cut-out 57 being formed as converging by flattened portions. A region of the second tier having the maximum radius defines a blocking section 60 at which a release section 62 is peripherally adjacently arranged which has a smaller radius than the blocking section 60. A part-cylindrical cut-out is provided in the second tier 50, in turn peripherally adjacent to the release section 62, and forms an assembly section 64. The assembly section 64 is continued in the third (i.e. middle) tier 52. A lock cylinder 66 in the form of a commercial half-profile cylinder is arranged beneath the rotational bolt 40 (Fig. 2). The lock cylinder 66 has a rotatable cylinder core 68 which is supported in a core reception section 70 and is rotatable about an axis of rotation. A flange section 72 in which pin tumblers 74 are arranged extends perpendicular to the axis of rotation. A threaded bore 76 for a cylinder fixing screw (not shown) is provided in the flange section 72. The core reception section 70 and the flange section 72 together form a cylinder housing 77 of the lock cylinder 66 (Fig. 2). A closing nose 78 rotationally fixedly connected to the cylinder core 68 is arranged at the longitudinal end of the cylinder core 68 (upper end in the position of use of the assembled lock cylinder 66). The closing nose 78 is thus rotatable together with the cylinder core 68 about its axis of rotation. The lock cylinder 66 furthermore comprises an integral support and covering section 80 at its rear end.

The lock cylinder 66 is held in an adapter piece 82 (Fig. 5) whose outer dimensions are adapted to the reception opening 36. The adapter piece 82 comprises an inner recess 84 adapted to the lock cylinder 66 as well as a support surface 86 at its end face (upper side in the position of use of the assembled adapter piece 82) and said support surface falls abruptly at two abutment surfaces 88a, 88b. In the outer jacket surface of the adapter piece 82 a part-cylindrical passage cut-out 90 is additionally provided which extends in parallel with the direction of the axis of rotation of the cylinder core 68. The adapter piece 82 has a peripheral interruption 92 which serves for the reception of the flange section 72 of the lock cylinder 66.

Fig. 6 shows the assembled padlock 10 in the latching position. The adapter piece 82 is permanently fastened in the lock body 12 (Figs. 1 and 2) by means of a pin (not shown) extending in the transverse direction. In the assembled state, the rotational bolt 40 lies with a lower end face of the second (i.e. lower) tier 50 on the support surface 86 of the adapter piece 82. In addition, the support and termination section 80 of the lock cylinder 66 extends through the cut-out 55 of the third (i.e. middle) tier 52 into the third tier 52 of the rotational bolt 40. In this respect, the rotational bolt 40 is rotatably supported at the support and termination section 80 of the lock cylinder 66 provided in extension for this purpose about an axis which corresponds to the named axis of rotation of the cylinder core 68 or of the closing nose 78.

The closing nose 78, whose rotational movement is bounded by the abutment surfaces 88a, 88b of the adapter piece 82, projects out of the cut-out 57 of the second tier 50 (Fig. 6a).

The lock cylinder 66 is held in the adapter piece 82, with the flange section 72 of the lock cylinder 66 projecting through the peripheral interruption 92 out of the adapter piece 82 radially to the axis of rotation of the rotational bolt 40. The adapter piece 82 and the lock cylinder 66 form at their lower ends a flush end which coincides with the lower side of the lock body 12.

The first shank 16 of the hoop 14 is configured substantially aligned with a radial end of the flange section 72 of the lock cylinder 66 in the direction of the axis of rotation of the rotational bolt 40.

The cylinder fixing screw is first removed from the lock body 12 for replacing the lock cylinder 66. Subsequently, the cylinder core 70 is rotated by the key 20 such that the closing nose 78 is oriented in alignment with the flange section 72 of the lock cylinder 66. In order in this respect to avoid a rotation of the rotating bolt 40, the cut-out 57 of the second tier 50 of the rotational bolt 40 is somewhat larger than the closing nose 78 so that a slight rotational clearance of the rotational bolt 40 results relative to the closing nose 78. In the aligned position of the closing nose 78, the lock cylinder 66 can be pulled out of the lock body 12 by means of the key 20.

On an insertion of the lock cylinder 66 (or of a different lock cylinder 66) into the reception opening 36 of the lock body 12 (i.e. into the adapter piece 82), the closing nose 78 is again oriented in alignment with the flange section 72 of the lock cylinder 66. The lock cylinder 66 is introduced so far into the lock body 12 until the support and termination section 80 of the lock cylinder 66 contacts the rotational bolt 40. The rotational bolt 40 thus lies in the axial extension of the cylinder core 70. Subsequently, the lock cylinder 66 is secured in the lock body 12 by means of the cylinder fixing screw. The key 20 can now be brought into a zero position and can be removed from the cylinder core 70, whereby the rotational bolt 40 is brought into the latching position in which the rotational bolt 40 is rotated relative to the flange section 72 of the lock cylinder 66.

In the latching position of the rotational bolt 40, the closing nose 78 of the lock cylinder 66 is rotated toward the drive surface 58a and the rotational bolt 40 is rotated so far that the drive surface 58 a, viewed in the direction of the axis of rotation, is oriented approximately in alignment with the abutment surface 88a of the adapter piece 82 (Fig. 6a). The blocking section 60 of the rotational bolt 40 is thereby arranged in the second blocking recess 24 of the hoop 14 (Fig. 6b). In addition, the blocking element 42 is urged by the drive section 54 of the rotational bolt 40 in the direction of the first blocking recess 22 of the hoop 14 and is held in its position by the corresponding section of the jacket surface of the first (i.e. upper) tier 48. With respect to the axis of rotation of the cylinder core 68 and thus to the axis of rotation of the rotational bolt 40, the blocking element 42 engages into the first blocking recess 22 of the hoop 14 in a radial direction and the blocking section 60 of the rotational bolt 40 engages into the second blocking recess 24 of the hoop 14 in a tangential direction.

If an attempt is made to remove the hoop 14 from the lock body 12 in the latching position, a lower surface of the hoop 14 defined by the second blocking recess 24 abuts the blocking section 60 of the rotational bolt 40. In addition, the radially outer semi-spherical section 44 of the blocking element 42 is wedged with the first blocking recess 22 of the hoop 14. In this manner, a removal of the hoop 14 in the latching position of the rotational bolt 40 is effectively prevented.

If the padlock 10 is to be unlatched and the hoop 14 released, the cylinder core 68 is rotated by means of the key 20 starting from the named zero position, whereby the closing nose 78 is likewise rotated (in the shown embodiment with a view from above counter clockwise) through the flange section 72 of the lock cylinder 66 to the other side of the flange section 72. The closing nose 78 in this respect first overcomes the named rotational clearance of the rotational bolt 40 before it is drive-effectively brought into contact with the drive surface 58b of the rotational bolt 40 and the rotational bolt 40 lying on the support surface 86 and on the support and termination section 80 is rotated counter clockwise. The drive section 54 of the rotating bolt 40 is thereby brought into the region of the radially inner semi-spherical section 44 of the blocking element 42, i.e. the blocking element 42 can escape back radially in the direction of the depression formed by the drive section 54. In addition, the release section 62 of the rotational bolt 40 is rotated into the angular region of the second blocking recess 24 of the hoop 14, i.e. the blocking section 60 of the rotational bolt 40 is rotated out of the second blocking recess 24. A rotation of the closing nose 78 only along a small angular region is required for this double latching action - despite the named rotational clearance of the rotational bolt 40. The closing nose 78 of the lock cylinder 66 in particular does not have to be brought into a rectangular alignment (90° position) relative to the flange section 72 of the lock cylinder 66 on any side of the flange section 72 of the lock cylinder 66. The lock body 12 can thus be relatively flat - as shown in the lower view in accordance with Fig. 4.

In this position of the rotational bolt 40 called a release position, the hoop 14 can be moved partly upwardly out of the lock body 12, whereby the blocking element 42 is urged into the drive section 54. On a moving out, the release recess 26 of the second hoop shank 18 and the release section 62 of the rotational bolt 40 move past one another until the securing section 30 of the second hoop shank 18 abuts the release section 62 from below. In this position, the rotational section 28 of the second hoop shank 18 is located at the tier of the release section 62 of the rotational bolt 40, whereby the hoop 14 is rotatable about the second shank 18.

In the release position, the closing nose 78 of the lock cylinder 66 contacts the abutment surface 88b of the adapter piece 82. To be able to move the rotational bolt 40 even further counter clockwise, the lock cylinder 66 has to be removed. With a removed lock cylinder 66, a rotation of the rotational bolt 40 beyond the release position into the so-called assembly position is possible. For this purpose, the rotational bolt 40 has an engagement slot 94 (Fig. 3a) e.g. for a screwdriver by means of which the rotational bolt 40 can be rotated into the assembly position with a removed lock cylinder 66. In the assembly position, the rotational bolt 40 is aligned such that the assembly section 64 is rotated into the angular position of the second hoop shank 18 and is thus arranged in alignment with the passage cut-out 90 of the adapter piece 82 in the axial direction. The securing section 30 is thus no longer blocked by the release section 62 of the rotational bolt 40 and the hoop 14 can be completely removed from the lock body 12.

Again starting from the release position, the hoop 14 is completely introduced into the lock body 12 for latching the padlock 10 and a rotation of the cylinder core 68 is carried out clockwise (with a view from above) by means of the key 20, said rotation rotating the rotational bolt 40 into the latching position shown (in Fig. 6). In this respect, the blocking element 42 is urged radially by the drive section 54 of the rotational bolt 40 into the first blocking recess 22 of the hoop 14 and the blocking section 60 of the rotational bolt 40 engages along its direction of rotation into the second blocking recess 24 of the hoop 14. An unauthorized opening of the hoop 14 is then no longer possible.
