Description

The present invention relates to a padlock with a lock body and a bracket, which is held displaceably on the lock body and having a first and a second leg. The padlock further comprises a rotary latch, which is rotatable about at least between a release position and a locking position about an axis of rotation, and at least one blocking element. The lock body comprises a first and a second receiving channel for receiving the first and second leg of the bracket and a receiving opening for interchangeable receiving a lock cylinder having a rotatable and with the rotary bolt drive-effectively coupled or coupled locking nose. The rotary latch comprises at least one drive section which is adapted, in the locking position of the rotary bolt, to urge the blocking element radially outward in the direction of a locking recess of the first leg with respect to the axis of rotation.

In such a padlock, the lock cylinder is actuated by a matching key to unlock. As a result, a cylinder core of the lock cylinder is rotated, the rotational movement is transmitted via the locking lug to the rotary latch. The closing nose of a lock cylinder is a rotary drive element which is eccentric with respect to the axis of rotation. The locking lug can be fastened in a variable angular position on the cylinder core of the lock cylinder. In the mounted state of the lock cylinder, however, the closing nose is non-rotatably connected to the cylinder core.

In the release position of the rotary latch, the bracket of the padlock can be opened, i. at least one leg of the bracket can be removed from the associated receiving channel of the lock body. In the locking position of the rotary bolt, however, both legs of the bracket are fixed in the associated receiving channels of the lock body.

For some applications, it is desirable that the lock cylinder of the padlock be replaced by the user. For example, due to the interchangeability of the lock cylinder, the padlock can be easily integrated into existing locking systems. Thus, a lock cylinder can be installed with a locking system associated closure in the padlock, whereby a key of the locking system can also be used for the padlock and thus results in a wide range of uses for the padlock. The padlock can be optionally equipped with a variety of lock cylinders - for example, from different manufacturers. The padlock can be offered for this purpose without its own lock cylinder, i. for retrofitting with its own lock cylinder by the user.

The locking cylinders used in such a padlock are usually standardized. This means that the padlock, at least in terms of the size of the associated receiving opening must be dimensioned so that it can accommodate the lock cylinder. In addition, it is possible to combine a conventional locking mechanism of a padlock with a replaceable lock cylinder. Known such padlocks, however, are undesirably large and / or material and labor intensive in the production.

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

This object is achieved by a padlock with the features of claim 1 and in particular in that the rotary latch further comprises a blocking portion which is adapted to engage in the locking position of the rotary latch with respect to the axis of rotation in the tangential direction in an associated locking recess of the second leg.

The bracket is thus secured in the locking position of the rotary bolt by two different locking methods in the lock body, namely on the one hand by the radially outwardly in the direction of the locking recess of the first leg crowded (at least one) blocking element. On the other hand, a blocking portion of the rotary latch in the tangential direction, i. along the direction of rotation of the rotary latch, brought into engagement with the locking recess of the second leg of the bracket. Advantageously, the rotation of the rotary bolt, which is necessary in any case, is used for additional locking of the bracket, whereby a double lock is achieved (i.e., locking of both arm legs). In addition, a conventional second blocking element can be saved in this case.

In addition, an eccentric arrangement of the axis of rotation of the rotary latch and / or an eccentric arrangement of the axis of rotation of the cylinder core of the lock cylinder in the lock body is possible by the use of the blocking portion of the rotary latch (in particular when the rotary latch engages over the blocking section directly into the locking recess of the second stirrup leg). The The axis of rotation of the rotary bolt and / or the cylinder core can be arranged near the second leg of the bracket, that is near an axis of the corresponding receiving channel of the lock body, whereby the lock cylinder can be better accommodated in the lock body and thus the dimensions of the lock body can be reduced.

The lock body can therefore be made smaller, in particular, because the lock cylinder only has to maintain a minimum distance to the axes of the receiving channels and thus to the legs of the bracket. In comparison to a centrally arranged between the receiving channels axis of rotation of the rotary latch and / or the cylinder core thus eliminates unused space in the lock body, whereby the padlock invention can be made more compact.

Advantageously, due to the compact design of the padlock according to the invention for the end user the usual appearance of a conventional padlock, since the lock body (i.e., the lock housing) can be made comparatively slim and the key insertion can be arranged as usual on the underside of the lock body.

According to the slim design results in a reduced material cost for the lock body, which is associated with low production costs.

The production process of the padlock can therefore also be carried out inexpensively, since the production of the receiving channels for the stirrup legs and the receiving opening for the lock cylinder, the introduction of only bores (ie straight holes of constant diameter) is required and undercuts (ie lateral recesses in the holes) can be avoided with the need of using special tools.

In addition, the padlock is particularly well protected against unauthorized opening (e.g., forcible removal of the strap from the lock body, manipulation of the lock mechanism) by the use of two different locking methods and directions of locking the two strap legs. For example, a method for violent radial retraction of the blocking element is not necessarily suitable for overcoming the tangentially guided blocking portion of the rotary latch.

Advantageously, the blocking portion of the rotary latch can engage directly in the locking recess of the second bracket leg. In this way, no mechanism connected between the rotary latch and the blocking section is needed, which in turn would increase the padlock.

For actuating the blocking element, the drive section forms a curved path deviating from a circular path for displacing the blocking element. Through the curved path, the blocking element can be moved radially outwardly during rotation of the rotary latch and thus engage in the locking recess of the first leg. When trying to remove the bracket in the locking position of the lock body, thus blocking the blocking element in the locking recess. At the same time, the blocking portion of the rotary latch lies flat against the associated locking recess, whereby the blocking element and the blocking section on both legs prevent the removal of the bracket. In particular, compared to the use of thin locking plates, the stability of the locking mechanism is increased by the combination of blocking element and blocking section.

Particularly well, the padlock according to the invention for exchangeable receiving commercially available lock cylinders with a rotatable locking lug, which is drivingly coupled to the rotary latch of the padlock. As a lock cylinder, in particular a commercial semi-cylinder can be used, since the lock cylinder is already accessible only on one side anyway when used in a padlock. For example, commercially available profile cylinders can be used without the need for mechanical adjustments DIN 18252 are standardized and the cylinder housing having a core receiving portion and a flange portion.

The insertion of the lock cylinder in the associated receiving opening of the lock body takes place from the side facing away from the bracket of the lock body, i. from the bottom in the position of use of the padlock. In general, the area of the bracket is referred to as the top side and the area facing away from the bracket as the bottom of the padlock.

The rotary latch may in particular be arranged within the receiving opening for the lock cylinder, that the rotary latch forms a stop for the lock cylinder during insertion of the lock cylinder in the lock body and the rotary latch thus in the axial direction between the upper-side boundary of the receiving opening and the lock cylinder (and / or an adapter piece, as will be explained below) is caught. By this arrangement, the rotary latch at the longitudinal end of the lock cylinder is a easy replacement of the lock cylinder possible because it can be removed or used on the underside of the lock body. When inserting and removing the rotary latch and the blocking element can remain in the lock body.

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

According to an advantageous embodiment, the axis of rotation of the rotary bolt and / or the axis of rotation of the locking nose (or cylinder core) of the lock cylinder accommodated in the receiving opening is arranged eccentrically with respect to the first and second receiving channels of the lock body (for the two shackles), i. the respective axis of rotation is not located exactly in the middle between the two receiving channels. The axis of rotation of the rotary latch can thus be closer to the second leg of the bracket, whereby the radius of the rotary latch can be reduced. Thanks to the reduced turning bolt, the padlock can again be designed to save space and material. If the axis of rotation of the locking nose or the cylinder core of the lock cylinder is closer to the second leg of the bracket, the lock cylinder can be better accommodated in the lock body.

According to a further advantageous embodiment, the axis of rotation of the rotary latch coincides with the axis of rotation of the closing nose (or of the cylinder core) of the lock cylinder accommodated in the receiving opening. In this way, during the insertion of the lock cylinder, the locking lug can be coupled to the rotary latch without complicated mechanics, e.g. by a direct positive connection. As a result, both the rotary latch and the lock cylinder (cylinder core) are off-center and thus particularly close to the second leg, whereby unnecessary space consumption is avoided.

According to a preferred embodiment, the drive portion and the blocking portion are integrally formed on the rotary latch. In particular, the drive portion and the blocking portion may thus be integrally formed with the rotary latch, whereby a rotary movement of the rotary latch is always transmitted to both the blocking element and the blocking and the rotary latch can engage directly in the associated locking recess of the second bracket leg on the blocking section. In this way, a secure and uniform locking of the padlock is ensured by means of the synchronously moving to the blocking portion blocking element.

Alternatively, however, the blocking portion may in principle also be formed as a separate part, which is rigidly connected or with torsional backlash with the rotary latch. For example, the blocking portion may be made of hardened metal, whereas the weight-saving rotating bolt may be formed of another material (e.g., plastic).

According to a further advantageous embodiment, the blocking element is elongated. In particular, such elongated extension of the blocking element may be provided along the direction of locking movement of the blocking element (i.e., in the radial direction with respect to the axis of rotation of the rotary latch). By the elongated blocking element of the conditional by the eccentric arrangement of the axis of rotation of the rotary latch distance between the drive portion of the rotary latch and the locking recess of the first leg is bridged.

Advantageously, the blocking element has at least one rounded, preferably circular, end. When trying to forcibly remove the strap from the lock body thus the circular end is wedged with the locking recess of the first stirrup leg, resulting in a circular distribution a favorable force distribution on an enlarged surface of the blocking element and the locking recess. The circular or rounded end thus complicates a shearing of the end of the blocking element. In this way, the force required to break the padlock can be greatly increased.

In particular, the shape of the elongate blocking element may be formed by two hemispheres connected by a cylindrical connecting portion.

Alternatively, at least two blocking balls can be provided as a blocking element, which are arranged one behind the other, wherein the force of the drive portion of the rotary latch is transmitted from the first to the second blocking ball.

According to a preferred embodiment, the blocking element and the blocking portion of the rotary bolt with respect to the axis of rotation of the rotary latch are arranged offset relative to each other. Seen along the axis of rotation, the blocking element and the blocking section can thus be arranged at different heights. For example, if the blocking portion of the rotary latch (and thus the associated locking recess of the second leg of the bracket when it is completely inserted into the lock body) in the lock body below, so when opening the bracket (in the release position of the rotary latch) only the locking recess of the first Legs are removed from the lock body, whereas the Locking recess of the second leg remains within the lock body.

Advantageously, the rotary latch comprises at least a first and second plane, which are each formed substantially disc-shaped and are arranged one above the other along the axis of rotation of the rotary latch. The rotary latch can thus be constructed tower-like, the centers of the discs are each on the axis of rotation of the rotary latch. Each of said planes may in particular extend perpendicular to the axis of rotation of the rotary latch.

The first plane preferably comprises the drive section and the second plane comprises the blocking section of the rotary latch. Due to the arrangement of blocking section and drive section on different planes, they can be offset relative to one another with respect to the axis of rotation. In addition, the mechanical load of the rotary latch can be distributed to the different levels.

The second level may include, in addition to the blocking portion, a release portion and, optionally, a mounting portion. In the region of the release portion, the second level of the rotary latch may have a smaller radius than in the region of the blocking portion, wherein by turning the rotary latch in the release position of the release portion of the rotary latch can be brought into the region of the second leg. As a result, no engagement of the release portion takes place in the locking recess of the second leg and the bracket can be partially removed from the lock body until, for example, a securing portion of the bracket rests flat against the release portion and thus prevents complete removal of the bracket from the lock body.

If the rotary latch is rotated further into a mounting position, the mounting portion of the rotary latch can be brought into the region of the second stirrup leg, wherein in the region of the mounting portion, the radius of the second plane is even lower than in the region of the release portion. As a result, the securing portion of the bracket can be moved past the mounting portion and the bracket completely removed from the lock body. Also can be introduced in this mounting position of the rotary latch of the bracket in the production of the padlock in the lock body.

According to a preferred embodiment, the rotary latch between the first and the second plane comprises a third plane in which the rotary latch can be mounted in the radial and / or axial direction on the lock cylinder. In this case, the first and the third level can be hollow and each provided with a circumferential recess. From the circumferential recess, for example, the flange portion of the lock cylinder protrude. At the same time, the rotary latch can form a stop for the lock cylinder in the axial direction.

The said lock cylinder does not necessarily have to be part of the padlock, namely if the padlock is intended to be retrofitted with a commercially available lock cylinder (for example an existing lock system). According to a preferred embodiment, however, the lock cylinder is part of the padlock. In this embodiment, the lock cylinder may comprise a cylinder housing rotatably mounted in a cylinder housing, with which said locking lug is rotatably connected.

Preferably, the locking lug of the lock cylinder protrudes into a recess of the rotary latch, wherein between the locking lug and the rotary latch preferably consists of a backlash. In particular, the locking lug can protrude into the said circumferential recess of the second level and come into contact with the side walls of the recess during a rotational movement of the closing lug in order to transmit a rotational movement of the closing lug to the rotary latch. In other words, the two lateral boundaries of the circumferential recess serve as stop edges. Due to the backlash, the locking lug of the lock cylinder when inserting the lock cylinder in the lock body can be easily inserted into the circumferential recess of the rotary latch and / or placed in a flush with the lock cylinder angular position to insert the lock cylinder in the lock body or remove from the lock body can.

Preferably, an adapter piece is arranged in the receiving opening of the lock body between the lock cylinder and the lock body, which forms a rotation stop for the locking lug of the lock cylinder in the release position and / or in the locking position of the rotary latch. A rotation of the rotary latch in an undesired position can thus be prevented by the adapter piece. At the same time, the adapter piece can at least partially adapt the contour of the receiving opening of the lock body to the contour of the lock cylinder, and the adapter piece can also hold the rotary latch and the blocking element within the receiving opening of the lock body. The adapter piece can be fixed, for example by means of a pin or a screw or by a press fit in the receiving opening of the lock body. Preferably, the adapter piece is permanently secured in the lock body. Alternatively, however, a releasable attachment may be provided in the lock body, whereby the padlock can be adapted by replacing the adapter piece to different lock cylinder.

According to a further advantageous embodiment, the receiving channels of the lock body (for the two bar arms) extend parallel to the axis of rotation of the rotary latch. As a result, the lock cylinder can be inserted from the underside of the padlock in this, resulting in the usual structure with a arranged at the bottom of the housing Schlüsseleinführöffnung for a user of the padlock.

According to a further advantageous embodiment, a through hole for a forend screw is provided in the lock body, by means of which the lock cylinder in the receiving opening of the lock body is securable. Thus, the lock cylinder is additionally secured by the forend screw against pulling out of the lock body.

Preferably, the lock cylinder is a according to DIN 18252 standardized profile cylinder, which comprises a cylinder housing with a hollow cylindrical core receiving portion for rotatably supporting the cylinder core and a radially projecting from the core receiving portion flange portion may be provided in the pin tumblers. The lock cylinder may thus be formed asymmetrically (ie not circular) in cross-section, wherein the cylinder housing, starting from a circular cross-section of the core receiving portion merges into an elongated flange portion. When the cylinder housing is inserted in the padlock (ie, in the associated receiving opening of the lock body), the core receiving portion of the cylinder housing can be closer to the axis of the second receiving channel of the lock body (for the second leg of the bracket), wherein the flange portion of the cylinder housing extends from the core receiving portion in the direction of the axis of the first receiving channel (for the first leg).

In particular, it is possible due to the inventive design of the rotary latch 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 receiving portion and the flange portion) with the center plane of the lock body, which through the axes of the two receiving channels of the lock body is clamped for the bar arms, coincides or runs parallel thereto. For this purpose, in particular a plane of symmetry of said receiving opening of the lock body coincide with the center plane of the lock body or run parallel thereto. Thus, the usual appearance of a conventional padlock in which the keyway of the lock cylinder (i.e., the slot-shaped key insertion opening of the cylinder core) extends along the center plane of the lock body or parallel thereto can be realized for the end user.

The invention will now be described by way of example only with reference to the drawings. Identical or similar elements are identified therein with the same reference numerals.

This in 1 shown padlock 10 includes a lock body 12 and a hanger 14 , The coat hanger 14 is U-shaped from a cylindrical material and includes a first leg 16 and a second leg 18 , The thigh 16 . 18 are each currently being trained.

The padlock 10 is by means of a key 20 from a locked state to an unlocked state and vice versa. The key 20 is in a key insertion opening on an underside of the lock body 12 insertable, which the hanger 14 opposite.

In 2 is the padlock 10 from 1 shown in exploded view. In the temple 14 is in the first leg 16 a first locking recess 22 provided at a lower end of the first leg 16 is arranged and cylindrical segment-shaped or spherical segment-shaped.

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

The second leg 18 is longer than the first leg 16 formed and includes in a below the end of the first leg 16 area located a second locking recess 24 , which is formed by removal of a cuboid region. To the second lock recess 24 closes below a release recess 26 which, by a the first leg 16 facing concave recess of the second leg 18 is formed.

Below the release recess 26 closes a rotary section 28 on, which has a circular cross section, which is opposite to the usual cross section of the bracket 14 is reduced, ie the rotary section 28 forms an annular groove.

The conclusion of the second leg 18 forms a security section 30 with round cross-section, the usual cross-section of the temple 14 equivalent.

In the locked state of the padlock 10 extends the first leg 16 in a first receiving channel 32 and the second leg 18 in a second receiving channel 34 of the lock body 12 into it. The recording channels 32 . 34 are outside the lock body 12 to recognize as top-side openings. The recording channels 32 . 34 are at the cross section of the temple 14 customized.

The lock body 12 is more detailed in 4 shown. The lock body 12 has a substantially rectangular cross section, wherein the longitudinal sides are curved outwardly. From below is in the lock body 12 a receiving opening 36 brought in. The receiving opening 36 tapers stepwise upwards. On one side surface is a through hole 38 intended for a forend screw.

Into the receiving opening 36 is a rotary latch 40 ( 2 ) used with a blocking element 42 directly in contact. The blocking element 42 has an oblong shape, which is defined by two hemispherical sections 44 and one of the hemispherical sections 44 connecting cylindrical section 46 educated.

The rotary latch 40 is tower-like constructed of three levels ( 3a ). In the installed state is a first level 48 the U-shaped area of the temple 14 turned and thus lies above. A second level 50 forms the lower end of the rotary bolt 40 , A third level 52 is between the first and the second level 48 . 50 arranged.

All levels 48 . 50 . 52 have - except for circumferential recesses and / or recesses - on a substantially cylindrical outer surface, wherein the radius of the planes increases from top to bottom. This means the radius of the first level 48 is smaller than the third level 52 , Again, the radius is the third level 52 smaller than the second level 50 ( 3b ).

In the first level 48 , That is, the upper level, a cylindrical recess is introduced, which, together with the circumferentially adjacent area as a drive section 54 serves.

The third level 52 , ie, the middle plane, is formed as a hollow cylinder, wherein a lateral surface is cut in an angular range of about 70 °. This recess 55 is by two stop surfaces 56a . 56b limited.

The second level 50 ie the lower level, includes a recess 57 its lateral surface of about 20 °, wherein the recess 57 defining drive surfaces 58a . 58b formed by flattening tapered. An area of the second level with the maximum radius defines a blocking section 60 to which circumferentially adjacent a release portion 62 is arranged, which has a smaller radius than the blocking portion 60 having. Again circumferentially adjacent to the release section 62 is a partially cylindrical recess in the second plane 50 provided, which is a mounting section 64 forms. The mounting section 64 sits down in the third (ie middle) level 52 continued.

Below the rotary latch 40 is a lock cylinder 66 arranged in the form of a commercially available semi-profile cylinder ( 2 ). The lock cylinder 66 has a rotatable cylinder core 68 which is in a core receiving section 70 is mounted and rotatable about an axis of rotation. Perpendicular to the axis of rotation extends a flange 72 in which pin tumblers 74 are arranged. In the flange section 72 is a threaded hole 76 for a forend screw (not shown). The core receiving section 70 and the flange portion 72 together form a cylinder housing 77 of the lock cylinder 66 ( 2 ).

At the longitudinal end of the cylinder core 68 (Upper end in the position of use of the assembled lock cylinder 66 ) is one with the cylinder core 68 non-rotatably connected locking nose 78 arranged. The closing nose 78 is thus together with the cylinder core 68 rotatable about its axis of rotation. The lock cylinder 66 further comprises an integral bearing and cover portion at its rear end 80 ,

The lock cylinder 66 is in an adapter piece 82 held ( 5 ), whose External dimensions to the receiving opening 36 are adjusted. The adapter piece 82 includes one to the lock cylinder 66 adapted inner recess 84 and on its front side (top in the position of use of the mounted adapter piece 82 ) a bearing surface 86 , which jump on two stop surfaces 88a . 88b drops. In the outer surface of the adapter piece 82 is also a partially cylindrical channel recess 90 provided, which is parallel to the direction of the axis of rotation of the cylinder core 68 runs. The adapter piece 82 has a major interruption 92 on, which is for receiving the flange portion 72 of the lock cylinder 66 serves.

6 shows the mounted padlock 10 in the locked position. The adapter piece 82 is by means of a transversely extending pin (not shown) in the lock body 12 ( 1 and 2 permanently attached. When mounted, the rotary latch is located 40 with a lower face of the second (ie lower) plane 50 on the support surface 86 of the adapter piece 82 , In addition, the storage and final section extends 80 of the lock cylinder 66 through the recess 55 the third (ie middle) level 52 to the third level 52 of the rotary latch 40 into it. Here is the rotary latch 40 at the core receiving portion 70 as well as at the storage and final section provided for this purpose in extension 80 of the lock cylinder 66 about an axis that is the said axis of rotation of the cylinder core 68 zbw. the closing nose 78 corresponds, rotatably mounted.

From the recess 57 the second level 50 protrudes the locking nose 78 out, their rotational movement through the stop surfaces 88a . 88b of the adapter piece 82 is limited ( 6a ).

The lock cylinder 66 is in the adapter piece 82 held, wherein the flange portion 72 of the lock cylinder 66 through the extensive interruption 92 from the adapter piece 82 radial to the axis of rotation of the rotary latch 40 protrudes. The adapter piece 82 and the lock cylinder 66 form at their lower end a flush conclusion, with the underside of the lock body 12 coincides.

The first leg 16 of the temple 14 is in the direction of the axis of rotation of the rotary latch 40 substantially in alignment with a radial end of the flange portion 72 of the lock cylinder 66 educated.

To replace the lock cylinder 66 First, the forend screw from the lock body 12 away. Subsequently, by the key 20 the cylinder core 70 twisted so that the locking lug 78 flush with the flange portion 72 of the lock cylinder 66 is aligned. To make a twist of the rotary latch 40 to avoid is the recess 57 the second level 50 of the rotary latch 40 slightly larger than the closing nose 78 formed, so that a slight torsional backlash of the rotary latch 40 relative to the locking nose 78 results. In the flush position of the locking nose 78 can the lock cylinder 66 by means of the key 20 from the lock body 12 be pulled out.

When inserting the lock cylinder 66 (or another lock cylinder 66 ) in the receiving opening 36 of the lock body 12 (ie in the adapter piece 82 ) becomes the locking nose 78 flush with the flange section 72 of the lock cylinder 66 aligned. The lock cylinder 66 gets so far into the lock body 12 introduced until the storage and finishing section 80 of the lock cylinder 66 at the rotary latch 40 is applied. The rotary latch 40 is thus in the axial extension of the cylinder core 70 , Subsequently, the lock cylinder 66 by means of the forend screw in the lock body 12 secured. Now the key 20 brought into a zero position and out of the cylinder core 70 be removed, causing the rotary latch 40 is brought into the locking position, in which the rotary latch 40 relative to the flange portion 72 of the lock cylinder 66 is twisted.

In the locking position of the rotary latch 40 presses the locking nose 78 of the lock cylinder 66 against the drive surface 58a and the rotary latch 40 is turned so far that the drive surface 58a , seen in the direction of the axis of rotation, approximately in alignment with the stop surface 88a of the adapter piece 82 is aligned ( 6a ). This is the blocking section 60 of the rotary latch 40 in the second locking recess 24 of the temple 14 arranged ( 6b ). In addition, the blocking element 42 through the drive section 54 of the rotary latch 40 in the direction of the first locking recess 22 of the temple 14 is urged and penetrated by the corresponding section of the lateral surface of the first (ie upper) level 48 held in their position. Relative to the axis of rotation of the cylinder core 68 and thus on the axis of rotation of the rotary latch 40 grab the blocking element 42 in the radial direction in the first locking recess 22 of the temple 14 and the blocking section 60 of the rotary latch 40 in the tangential direction in the second locking recess 24 of the temple 14 one.

Attempted in the locked position, the bracket 14 from the lock body 12 To remove, so a lower beats through the second locking recess 24 defined area of the temple 14 at the blocking section 60 of the rotary latch 40 at. In addition, the radially outer hemispherical section wedged 44 of the blocking element 42 with the first locking recess 22 of the temple 14 , In this way, a removal of the strap 14 in the locking position of the rotary latch 40 effectively prevented.

Shall the padlock 10 unlocked and the strap 14 be released, so by means of the key 20 starting from the said zero position of the cylinder core 68 twisted, which also causes the locking nose 78 (In the embodiment shown in top view counterclockwise) through the flange portion 72 of the lock cylinder 66 through to the other side of the flange portion 72 is twisted. The closing nose 78 initially overcomes the aforementioned torsional backlash of the rotary latch 40 before using the drive surface 58b of the rotary latch 40 drivably brought into contact and on the support surface 86 and the storage and finishing section 80 resting rotary bolt 40 is rotated counterclockwise. This will cause the drive section 54 of the rotary latch 40 in the region of the radially inner hemispherical section 44 of the blocking element 42 brought, ie the blocking element 42 can be radial in the direction of the drive section 54 recede formed well. In addition, the release section 62 of the rotary latch 40 in the angular range of the second locking recess 24 of the temple 14 rotated, ie the blocking section 60 of the rotary latch 40 becomes from the second lock recess 24 unscrewed. For this double locking effect is - despite the mentioned backlash of the rotary latch 40 - A rotation of the locking lug 78 only required along a small angular range. In particular, the locking nose needs 78 of the lock cylinder 66 on neither side of the flange section 72 of the lock cylinder 66 in a rectangular orientation (90 ° position) relative to the flange portion 72 of the lock cylinder 66 to be brought. Thus, the lock body 12 - as in the bottom view according to 4 shown - be made relatively flat.

In this designated as release position position of the rotary latch 40 can the temple 14 partly upwards out of the lock body 12 be moved out, causing the blocking element 42 in the drive section 54 is urged. When moving out, the release recess move 26 of the second stirrup leg 18 and the release section 62 of the rotary latch 40 past each other until the fuse section 30 of the second stirrup leg 18 from below on the release section 62 strikes. In this position is the rotary section 28 of the second stirrup leg 18 at the level of the clearance cutout 62 of the rotary latch 40 , causing the hanger 14 around the second leg 18 is rotatable.

In the release position is the locking nose 78 of the lock cylinder 66 at the stop surface 88b of the adapter piece 82 at. To the rotary latch 40 to be able to move even further counterclockwise, the lock cylinder must 66 be removed. With the lock cylinder removed 66 is a rotation of the rotary latch 40 beyond the release position into the so-called assembly position possible. For this purpose has the rotary latch 40 an engagement slot 94 ( 3a ) eg for a screwdriver, by means of which the rotary latch 40 with the lock cylinder removed 66 can be rotated in the mounting position. In the installation position is the rotary latch 40 aligned such that the mounting portion 64 in the angular range of the second stirrup leg 18 rotated and thus aligned in the axial direction with the channel recess 90 of the adapter piece 82 is arranged. Thus, the security section 30 no longer through the release section 62 of the rotary latch 40 blocked and the hanger 14 can completely out of the lock body 12 be removed.

Again starting from the release position is to lock the padlock 10 the coat hanger 14 completely in the lock body 12 introduced, and by means of the key 20 will be a rotation of the cylinder core 68 (when viewed from above) in a clockwise direction, which is the rotary latch 40 into the (in 6 ) shown locking position rotates. In this case, the blocking element 42 from the drive section 54 of the rotary latch 40 radially into the first locking recess 22 of the temple 14 urged and the blocking section 60 of the rotary latch 40 engages along its direction of rotation in the second locking recess 24 of the temple 14 one. An unauthorized opening of the bracket 14 is then no longer possible.
