Description

Padlock basic kit and padlock system

The invention relates to a padlock basic kit for assembling a padlock in a configuration selectable from a plurality of configurations. The configurations from which each can be selected differ with regard to the type of lock cylinder used in the padlock. The basic kit thus enables a respective lock cylinder to be selected from lock cylinders of different types and used for assembling a padlock. Such a basic kit is therefore suitable both for assembling a padlock with a lock cylinder of a specific type and for assembling a padlock with a lock cylinder of a specific different type. Thus, the basic kit is not limited to a single lock cylinder type, but can be used in a variety of ways, since a padlock with a lock cylinder of the preferred type can be assembled as required using the same basic kit.

In addition, the configurations can also differ, at least optionally, with regard to the type of hasp used in the padlock. Such a padlock basic kit thus makes it possible to assemble either a padlock with a hasp of a specific type or a padlock with a hasp of a specific other type. In such a basic kit, the possible configurations differ from one another in pairs either with regard to the type of lock cylinder or with regard to the type of striker or with regard to the respective type of both components. It cannot be ruled out that the overall possible configurations in which a padlock can be assembled using the padlock basic kit will differ with regard to other components, which may be of different types. It is a general goal that the padlock basic kit can be used to create a padlock that is as compact as possible in as many different configurations as possible, especially with regard to locking cylinders that can be used in the padlock, which at the same time has the highest possible level of security, for example at least the requirements of the class CEN 5 of DIN EN 12320:2012-12 fulfilled.

The invention also relates to a padlock system for the variable formation of padlocks in various configurations, which differ in terms of the type of in the respective differentiate between the lock cylinder used in the padlock. In contrast to the basic kit, such a system includes all the basic components to be able to assemble padlocks in the various configurations, ie in particular lock cylinders of different types. Optionally, the configurations of such a padlock system can also differ in the same way as in the padlock basic kit with regard to the type of hasp used in the respective padlock, with the system then also including different types of hasps in contrast to the corresponding basic kit.

Lock cylinders are used in very different types of locks. The lock cylinder essentially serves to be rotated and to transmit this rotation to a bolt mechanism of the respective lock, the lock cylinder being designed to only allow rotation if this is done using a key assigned to the lock cylinder. The lock cylinder ensures that the lock can only be actuated by means of the key, in particular only unlocked by means of the key, and possibly only locked by means of the key. Different lock cylinders have been developed for different types of locks, which are adapted in a special way to the respective lock and therefore differ in terms of their shape and dimensions, especially with regard to their profile, and the respective mechanism for releasing or blocking a rotary actuator be able.

For example, so-called profile cylinders are typically used for door locks, the profile of which, i.e. the basic cross-section that is essentially constant over the entire length and transverse to the direction in which the key is inserted into the lock cylinder, is standardized. This profile comprises a circular cylinder section, in which the cylinder core is accommodated, as well as a web section protruding radially from the center point of the cylinder section for receiving the tumblers, the width (tangential extension) is smaller than the diameter of the cylinder section and the length (radial extension) corresponds approximately to the diameter of the cylinder section. However, there are also numerous lock cylinders of other types with a large number of different profiles.

However, the basic functional principle of the locking cylinder is usually the same in each case. It is therefore fundamentally conceivable to use locking cylinders of different types for a specific lock. This has the advantage that the lock can be variably assembled in different configurations by depending on the desired configuration with a lock cylinder of a respective type, in particular a respective profile, is equipped. For example, the benefit of assembling a lock in different configurations may be that a particular lock can easily be offered one time with a lock cylinder that offers normal tamper resistance and another time with a higher quality lock cylinder that offers improved protection against tampering. The advantage of being able to use different lock cylinders for the same lock can also consist in the fact that one or the other type of lock cylinder can be used for assembling the lock, depending on the availability of different lock cylinders.

Padlocks, in particular, can be used in many different ways for very different purposes, with different locking cylinders being advantageous depending on the area of use. Therefore, a high degree of variability is desirable, especially with padlocks. The variability can not only consist in the fact that the padlock can be assembled in different configurations, but the variability can also advantageously include the fact that the padlock can be reconfigured relatively easily, i.e. in particular the lock cylinder installed in the padlock can be exchanged for a lock cylinder from another type can be exchanged.

If a basic kit for a padlock is designed so that lock cylinders of different types, in particular different profiles, can be used for the padlock, the problem arises that each of the different lock cylinders can be accommodated and fastened in the padlock essentially equally reliably, despite the different design have to be. In particular, enabling the various configurations must not result in the padlock in some or even all configurations offering deteriorated security compared to a conventional padlock, for example because there are more access options for manipulation of the lock cylinder due to gaps or the lock cylinder due to a poorly secured Fastening can be removed more easily from the padlock.

It is an object of the invention to provide a padlock basic kit and a padlock system of the type mentioned above, which offer a high degree of variability with regard to the configuration of the padlock to be assembled, while still ensuring reliable and safe assembly of the padlock.

The object is achieved by a padlock basic kit with the features of claim 1 and by a padlock system with the features of claim 17. Partial embodiments result from the dependent claims, the present description and the figures.

The padlock basic kit according to the invention for assembling a padlock in a configuration that can be selected from several configurations, the configurations differing in terms of the type of lock cylinder used in the padlock and optionally also in terms of the type of hasp used in the padlock, comprises a lock body, at least two various locking cylinder adapters and a locking plate. The lock cylinders of different types differ in particular at least with regard to their respective profile, i.e. their cross section transverse to a key insertion direction in which a key assigned to the respective lock cylinder can be inserted into the lock cylinder. In particular, the cross section can be constant at least essentially over the entire length (extension in the key insertion direction) of the lock cylinder. In any case, preferably no section of the lock cylinder extends transversely to the key insertion direction beyond the cross section. In this case, the profile corresponds to the outer contour of the lock cylinder when viewed in the direction parallel to the key insertion direction.

A first of the at least two lock cylinder adapters has a receiving channel that is designed to receive a lock cylinder of a first type, and a second of the at least two lock cylinder adapters has a receiving channel that is designed to receive a lock cylinder of a second type . The padlock basic kit can also include additional lock cylinder adapters, each of which has a receiving channel that is designed to receive a lock cylinder of a different type.

The fact that the receiving channels are each designed to receive a lock cylinder of a respective type preferably means that the lock cylinder fits exactly into the receiving channel, in particular in such a way that it rests flush against the receiving channel at least substantially over the entire circumference after receiving. The receiving channels of the lock cylinder adapters can in particular each be designed to be continuous, ie they can extend from an outer side of the respective adapter to an outer side opposite thereto. Furthermore, the receiving channels each preferably have a constant cross-section transversely to the direction of their extension in or through the respective adapter, at least in regions. Furthermore, the lock body has a lock cylinder receptacle, which extends in a longitudinal direction into the lock body and is designed to selectively accommodate the first lock cylinder adapter with a lock cylinder of the first inserted therein, i.e. received in the receiving channel of the first lock cylinder adapter Type or the second lock cylinder adapter with a inserted therein, ie received in the receiving channel of the second lock cylinder adapter, lock cylinder of the second type.

The lock cylinder receptacle can, for example, extend into the lock body from an end face of the lock body, which corresponds to that side of the padlock to be assembled, on which the key is inserted into the respective lock cylinder of the padlock. The lock cylinder receptacle preferably does not extend through the lock body, but rather ends within the lock body, and it can also open into another cavity in the lock body, e.g. a rotary bolt receptacle for receiving a rotary bolt that interacts with the lock cylinder.

The lock cylinder receptacle of the lock body is preferably designed to optionally accommodate the first lock cylinder adapter with a lock cylinder of the first type inserted therein, the second lock cylinder adapter with a lock cylinder of the second type inserted therein, or a lock cylinder of a third type. Unlike when using a lock cylinder of the first type or the second type, the lock cylinder of the third type is accommodated directly in the lock cylinder receptacle of the lock body, i.e. without being inserted into a lock cylinder adapter, which in turn is accommodated in the lock cylinder receptacle will.

Correspondingly to the receiving channels, the design of the lock cylinder receptacle to receive a lock cylinder of the third type preferably includes the lock cylinder fitting exactly into the lock cylinder receptacle, in particular in such a way that after it has been received it is at least essentially completely flush with the lock cylinder -Recording pending.

The design of the lock cylinder receptacle of the lock body in relation to the at least two lock cylinder adapters for lock cylinders of the first or second type and, if applicable, to the lock cylinder of the third type makes it possible for the basic kit not to be limited to a specific type of lock cylinder, but that either a locking cylinder of the first or the second type with the respective speaking lock cylinder adapter or possibly also a lock cylinder of the third type can be used without a lock cylinder adapter in the lock cylinder receptacle. Thus, using the basic kit according to the invention, a padlock can be assembled in at least two, preferably three, different configurations that differ in terms of the type of lock cylinder used in the padlock, with only two different lock cylinder adapters being required. The desired configuration can be freely selected. For example, the type of lock cylinder used for the padlock to be assembled can be selected depending on the level of security desired for the padlock.

According to the invention, it is further provided that the closure plate is designed to close the lock cylinder receptacle in such a way that it essentially completely covers, in particular apart from, a respective lock cylinder accommodated in the lock cylinder receptacle (depending on its type with or without a lock cylinder adapter). by a key opening formed in the lock plate for inserting a key into the respective lock cylinder.

The locking plate can completely cover the locking cylinder accommodated in the locking cylinder receptacle, in particular to the extent that the locking cylinder is located completely within an outer contour of the locking plate when projecting parallel to the mentioned longitudinal direction, regardless of what type of locking cylinder it is acts.

The closure plate can consist of a hardened metal, for example. The lock cylinder receptacle is preferably closed by fastening the locking plate in an opening area of the lock cylinder receptacle. In this case, the opening area can in particular directly adjoin the named end face, from which the lock cylinder receptacle extends into the lock body.

By closing the lock cylinder mount, the locking plate (separate from the lock cylinders and lock cylinder adapters) not only holds the respective lock cylinder, possibly including the corresponding lock cylinder adapter, securely in the lock cylinder mount, but also prevents access by covering it to the lock cylinder from the outside - possibly disregarding access to a key channel in a cylinder core of the respective lock cylinder, which may be necessary for inserting a key. In this way it can be done using the Padlock created from the basic kit has a particularly safe and reliable assembly despite the variability in terms of the locking cylinder used.

According to an advantageous embodiment, it is provided that the receiving channel of the first lock cylinder adapter extends along an insertion direction into the first lock cylinder adapter and at least partially has a constant receiving cross section that is complementary to the profile of a lock cylinder of the first type (so that a Lock cylinder of the first type can be inserted into the receiving channel of the first locking cylinder adapter in the insertion direction), and that the receiving channel of the second locking cylinder adapter extends along an insertion direction into the second locking cylinder adapter and, at least in some areas, has a constant receiving cross section that is complementary to the profile of a lock cylinder of the second type (so that a lock cylinder of the second type can be inserted in the insertion direction into the receiving channel of the second lock cylinder adapter), the lock cylinder receptacle of the lock body has a constant receiving cross-section at least in some areas with respect to the longitudinal direction, and the at least two lock cylinder adapters each have a profile that is complementary to the receiving cross-section of the lock cylinder seat of the lock body (so that optionally one of the at least two lock cylinder adapters with a inserted lock cylinder of the first or second type can be inserted into the lock cylinder receptacle, in particular with the insertion direction aligned parallel to the longitudinal direction of the lock body).

If the lock cylinder receptacle of the lock body is designed to optionally receive the first lock cylinder adapter with a lock cylinder of the first type, the lock cylinder adapter with a lock cylinder of the second type or a third lock cylinder adapter, the cross section of the receptacle of the lock cylinder receptacle of the lock body is preferably complementary to the profile of a lock cylinder of the third type. In this case, the profiles of the two locking cylinder adapters correspond to the profile of a locking cylinder of the third type.

The receiving cross-sections mentioned in each case limit the maximum cross-section that an object can have that is received in the insertion direction or longitudinal direction in the receiving channel of the respective lock cylinder adapter or in the lock cylinder receptacle of the lock body. The receiving cross-sections of the receiving channels of the lock cylinder adapter are each related to the direction of insertion of the respective adapter, while the receiving cross-section of the lock cylinder receptacle of the lock body is related to the longitudinal direction. The receiving cross sections of the receiving channels of the lock cylinder adapter and the receiving cross section of the locking cylinder receptacle of the lock body do not necessarily have to be constant throughout, but can only be constant at least in certain areas, in particular insofar as the cross section can be expanded in other areas, for example to form an undercut . In addition, cavities formed deeper in the lock body and adjacent to the lock cylinder receptacle can also have narrower cross sections, although such areas are not taken into account since they are not used to accommodate a lock cylinder or lock cylinder adapter and are therefore not part of the lock cylinder receptacle.

The profiles of the lock cylinders or lock cylinder adapters each correspond to an outer cross section of the respective lock cylinder, in particular a cylinder housing of the respective lock cylinder, or an outer cross section of the respective lock cylinder adapter transverse to the direction in which a key is inserted or removed from the lock cylinder. a lock cylinder can be inserted into the lock cylinder adapter. In particular, all lock cylinders of the same type each have the same profile, while lock cylinders of different types have different profiles in relation to one another.

As a result of the aforementioned complementary design of a respective receiving cross section to a respective profile, the profile and the receiving cross section are flush with one another when inserted, which ensures a secure and stable seat of the respective lock cylinder or the respective lock cylinder adapter in the respective lock cylinder adapter or the lock body is achieved. Certain tolerances can be provided, e.g. a clearance fit, which facilitates insertion or replacement. Alternatively, a transition fit can also be provided for a firmer fit. If simple interchangeability is not desired, a press fit can also be considered, at least in principle.

According to an advantageous embodiment, lock cylinders of a particular type, in particular, for example, the first type mentioned, have a profile which comprises a circular cylinder section and a web section which protrudes radially from the cylinder section with respect to the center point of the cylinder section and is preferably rounded at its free end, the width of which is ( tangential extent) is less than the diameter of the circular shape of the cylinder section and whose length (radial extent) corresponds at least essentially, preferably up to a maximum of one millimeter, to the diameter of the cylinder section. All locking cylinders of this type preferably have the same file up. In particular, the locking cylinders of this type can be what are known as profile cylinders, for example in accordance with the DIN EN 1303/2005 standard. Accordingly, the diameter of the circular shape of the cylinder section can be, for example, 17 mm, the width of the bar section can be, for example, 10 mm and the length of the bar section can be, for example, 16.3 mm, so that the profile along the direction in which the bar section extends has a total extent of, for example 33.3 mm.

According to an advantageous embodiment, locking cylinders of a particular type, in particular, for example, the second type mentioned, have a profile that includes a circular cylinder section and a tumbler section with a circular contour that is offset relative to the cylinder section, so that the cylinder section and the tumbler section together have the shape of two offset cylinders and partially overlapping circular areas. In particular, it can be provided that the two circular surfaces have at least essentially the same diameter, i.e. apart from a few, preferably one, millimetres. In addition, the offset between the circular areas can in particular be less than the diameter of the circular areas (in the case of different diameters: the larger circular area), so that the profile has at least essentially the shape of a figure eight. All lock cylinders of this type preferably have the same profile.

According to an advantageous embodiment, locking cylinders of a particular type, in particular, for example, the third type mentioned, have a profile whose shape corresponds to the convex envelope of two mutually offset circular surfaces which preferably have at least essentially, i.e. up to a few, preferably one, millimeters, the same diameter exhibit. All lock cylinders of this type preferably have the same profile. In particular, the locking cylinders of this type can be so-called oval cylinders, e.g. according to the DIN EN 1303/2005 standard. Accordingly, the diameter of both circular areas can each be 20 mm, for example, and the offset of the two circular areas can be 15 mm, for example, so that the profile has a total extension of 35 mm, for example, along the direction of the offset.

Furthermore, it is preferred if the profiles of at least two lock cylinder types are designed in the above-mentioned manner. It is particularly preferred if the lock cylinder receptacle of the lock body is designed to accommodate a lock cylinder of a first type, a lock cylinder of a second type or a lock cylinder of a third type either by means of a respective lock cylinder adapter or directly (i.e. without a lock cylinder adapter). , The profiles of all three lock cylinder types are designed in one of the above-mentioned ways. According to an advantageous embodiment, the basic kit comprises at least two different rotary bolts, each of which is designed to be mounted in the lock body so that it can rotate about an axis of rotation parallel to the longitudinal direction, in order, depending on the rotary position, to prevent a striker, which is displaceably mounted on the lock body, from leaving a closed position lock, with a first of the at least two rotary bolts being designed to be coupled in a rotationally effective manner to a driver section of a lock cylinder of at least one of the types mentioned, and a second of the at least two rotary bolts being designed to be coupled to a driver section of a lock cylinder of at least one other of the types mentioned to be rotationally coupled. At least one of the two rotating bolts is preferably designed to be able to be coupled in a rotationally effective manner to the respective driver section of two lock cylinder types.

In such an embodiment, depending on the lock cylinder used, a rotary bolt suitable for rotationally effective coupling with its driver section can be selected from the various rotary bolts and used for assembling the padlock. In particular, the rotary bolt can be rotatably mounted in the lock body in such a way that its axis of rotation is coaxial with the axis of rotation of a cylinder core of the respective lock cylinder accommodated in the lock body (with or without a lock cylinder adapter, depending on the type).

The driver sections of the lock cylinders can each be, for example, a structure that protrudes axially from the cylinder core with respect to an axis of rotation of a cylinder core of the respective lock cylinder, which can be aligned in particular parallel to the longitudinal direction mentioned, with a complementary structure on an axial end face of the respective Rotating bolt-trained structure can be brought into coupling engagement. If a rotating bolt is designed in such a way, it can simply adjoin the lock cylinder axially for the rotationally effective coupling. One of the structures mentioned can be designed as a web, for example, while the other can then be designed as a groove.

However, the driver sections can each also be designed as a structure that protrudes radially with respect to the axis of rotation of the cylinder core of the respective lock cylinder, for example in the manner of a so-called locking nose of a profile cylinder. In such a design, it is expedient if the rotating bolt at least partially surrounds at least one end section of the respective lock cylinder or the respective lock cylinder adapter with the respective lock cylinder inserted therein in the direction of rotation around the axis of rotation. Of the In this respect, the twist lock can be designed to be slipped onto the named end section, in particular in the radial direction.

In particular, the driver section, to which the first rotary bolt can be rotationally operatively coupled, and the driver section, to which the second rotary bolt can be rotationally operatively coupled, can differ.

Accordingly, according to an advantageous embodiment, it is provided that the first rotating bolt is designed to be rotationally coupled to a driver section of a lock cylinder of at least one of the types mentioned, which is formed by a structure that protrudes radially from the cylinder core with respect to an axis of rotation of a cylinder core of the respective lock cylinder , and the second rotating bolt is designed to be rotationally coupled to a driver section of a lock cylinder of at least one other of the types mentioned, which is formed by a structure that protrudes axially from the cylinder core with respect to an axis of rotation of a cylinder core of the respective lock cylinder.

For said locking of the respective striker by means of a respective rotary bolt, the rotary bolts do not necessarily have to be designed to interact directly with the striker. Rather, provision can be made for the locking to take place indirectly, e.g. via one or more locking elements mounted movably in the lock body radially to the axis of rotation of the rotating bolt.

According to an advantageous embodiment, it is provided that the basic kit comprises two locking elements, in particular in the form of locking balls, which are arranged diametrically with respect to the axis of rotation and are mounted so that they can move radially, and that the rotating locks each have a control section which is at least essentially cylindrical in shape, on whose two diametrically opposed recesses are formed on the outer circumference with respect to the axis of rotation, whereby a control link is formed for the locking elements, which forces the locking elements into a locking position, depending on the rotational position of the rotary bolt, in which they lock the striker against leaving the closed position, or for a radial movement releases. In this respect, the rotating bolts can each be designed in particular in the manner of a so-called spherical slide.

According to a further advantageous embodiment, the closure plate has a key opening for inserting a key through the key opening in the respective lock cylinder used in the lock cylinder receptacle of the lock body, the Key opening has at least essentially the shape of two mutually oppositely arranged sectors of a circle with an identical central angle. The central angles can, for example, have a size between 45° and 90°, preferably between 55° and 70°, in particular about 65°. The centers of the circle sectors do not necessarily have to lie on top of each other. Rather, the circle sectors can overlap each other with their tips by an amount that essentially corresponds to the thickness of the respective key. This creates a kind of butterfly shape.

Said design of the key opening allows both the insertion of the key and turning of the inserted key through an angle which is limited by the central angle mentioned. The center angle is therefore advantageously chosen such that it corresponds to the angle of a rotation of the cylinder core required for actuation of the lock cylinder. The key opening is preferably minimal, i.e. it is only as large as is absolutely necessary for the insertion and turning of the key. In this way, the locking cylinder used in the lock body is covered to the maximum extent by the locking plate and secured against unauthorized access from the outside.

In order to fasten the closure plate to the lock body so that it can securely close the lock cylinder receptacle, an undercut can be formed in the lock cylinder receptacle, in particular in the mentioned opening area of the lock cylinder receptacle, into which the closure plate can engage with a projection . Inserting the closure plate to close the lock cylinder receptacle can then involve bringing the projection of the closure plate into engagement with the undercut at an angle to the longitudinal direction and then pivoting the closure plate about a pivot axis defined by this engagement into a position in which it Lock cylinder receptacle locked perpendicular to the longitudinal direction. In order to be reliably secured in this locking position, the locking plate can then be lockable on the lock body, in particular on its side opposite the said projection.

According to a further advantageous embodiment, it is provided that the lock body has a screw channel for a screw, by means of which the locking plate can be locked when it closes the lock cylinder receptacle, with the screw channel extending into the lock body transversely to the longitudinal direction, and that the Lock body also has a blocking channel for a blocking element, which opens parallel to the longitudinal direction in the screw channel to block access from the outside through the screw channel to the screw by means of the blocking channel inserted into the locking channel and engaging in the screw channel locking element. The screw channel and the locking channel each preferably have a straight course.

The screw channel can in particular extend from the outside into the lock body and open into the lock cylinder receptacle so that the screw can be screwed into the screw channel from the outside and screwed against or into the locking plate inserted into an opening area of the lock cylinder receptacle in order to lock it . The screw can, for example, be a so-called grub screw, i.e. a threaded pin. In principle, it can be provided that the screw for locking the closure plate is only screwed so tightly against a side surface of the closure plate that the closure plate is locked by the screw in a clamping manner.

However, the closure plate preferably has a recess or undercut into which the screw engages in the screwed-in state in order to lock the closure plate. The recess can also be designed as a threaded bore into which the screw can be screwed for a particularly firm locking. If the closure plate has the aforesaid projection for engaging in an undercut of the lock cylinder receptacle, the closure plate preferably interacts with the screw on its side opposite this projection. In particular, said recess can be formed on the side of the closure plate opposite the projection.

In order to prevent the locking plate from being unlocked simply by unscrewing the screw, access to the screw from the outside through the screw channel is suitably blocked by means of the blocking element by inserting the blocking element into the blocking channel. Since the blocking channel opens into the screw channel, which can also include crossing the screw channel, the blocking element can be used in such a way that it engages in the screw channel, i.e. it extends at least into the screw channel or even through the screw channel, so that it it is not possible to remove the screw from the screw channel past the blocking element. The blocking element is designed, for example, as a preferably at least essentially cylindrical blocking pin or blocking bolt. However, the blocking element can also be designed as a small plate. The blocking channel advantageously has a cross section that is complementary to the cross section of the blocking element.

According to an advantageous further development of such an embodiment, the lock body is designed so that the blocking element only has a trained in the lock body Striker recording for receiving a leg of a hasp used in the padlock can be removed from the locking channel. This has the advantage that access to the screw for unlocking the locking plate can only be permitted by removing the blocking element if the striker holder is free and the padlock is not locked. In this way, unlocking the locking plate requires opening the padlock, so that locking the locking plate is just as secure as locking the padlock as a whole.

In particular, the blocking channel can extend from the striker receptacle to the screw channel. If the blocking channel extends further beyond the screw channel, it preferably ends inside the lock body, ie before it reaches an outside of the lock body. In this case, however, a passage to the outside of the lock body can be provided in an extension of the blocking channel, which passage has a different, in particular (much) smaller cross section than the blocking channel. Such a passage can be used to insert a (narrow) tool, e.g. a needle, by means of which the blocking element can be pushed through the passage in the direction of the striker retainer until it has at least left the screw channel.

The various ways in which the locking plate can be designed and lock the lock cylinder receptacle are also advantageous independently of a padlock basic kit and are part of a separate aspect of the invention that is fundamentally independent of the padlock basic kit. In this respect, the invention also relates to a padlock that includes a lock body with a lock cylinder receptacle for receiving a lock cylinder and a locking plate that is designed to close the lock cylinder receptacle in such a way that they receive a respective lock cylinder receptacle Lock cylinder is essentially completely concealed, with an undercut being formed in the lock cylinder receptacle, in particular in an opening area of the lock cylinder receptacle, and the closure plate being designed to engage in the undercut with a projection and, in particular, on one opposite the projection side of the lock plate to be locked to the lock body.

For this purpose, the lock body can have a screw channel for a screw, which extends from the outside into the lock body and opens into the lock cylinder receptacle, so that the screw can be screwed against the locking plate or into an engagement section of the locking plate, e.g. a recess or undercut to lock the locking plate when it locks the lock cylinder receptacle. But he can The lock body also has a blocking channel for a blocking element, which opens into the screw channel, so that by inserting the blocking element into the blocking channel in such a way that the blocking element engages in the screw channel, access from the outside through the screw channel to the screw can be at least partially blocked. Preferably, the lock body is designed so that the blocking element can only be removed from the locking channel via a striker receptacle formed in the lock body, which is designed to receive a leg of a striker used in the padlock. For example, the blocking channel can extend from the striker retainer to the screw channel.

Furthermore, the locking plate can have a key opening for inserting a key through the key opening into the respective lock cylinder inserted into the lock cylinder receptacle of the lock body, the key opening being at least essentially in the form of two circular sectors arranged opposite one another and having an identical central angle.

Otherwise, the lock body, the locking plate, the screw channel, the screw, the locking channel, the locking element and/or the striker retainer can each be designed in one or more of the ways described above or below for the respective corresponding element of a padlock basic kit . This relates in particular to the shape, the spatial position and/or the spatial orientation of the respective element.

According to an advantageous embodiment of the padlock basic kit, the lock body has a first striker mount and a second striker mount, which extend parallel to the longitudinal direction into the lock body and are designed to accommodate one of two legs of a striker, the basic kit a reducer adapted to be inserted into the first striker seat to reduce the depth thereof, i.e. the longitudinal extent thereof from the entrance to the bottom of the respective striker seat. The striker retainers preferably have identical, in particular circular, cross sections.

The striker retainers of a padlock are advantageously adapted to the lengths of the two legs of a respective striker provided on the padlock. In particular, one of the legs can be longer than the other, which makes it possible even with a rigid hasp that when the padlock is opened, only one of the Leg exits from the striker retainer assigned to it, while the other leg is only displaced in the striker retainer assigned to it, without leaving it completely, so that the striker does not have to be completely detached from the lock body to open the padlock.

Different strikers can have legs with different length differences. By providing a reducing element as part of the padlock basic kit, the difference in the depths of the two hasp receptacles can be optionally set (by inserting or omitting the reducing element) to two different values, which can correspond to the length differences of two different types of hasp. In this way, the variability made possible by the padlock basic kit is expanded even more when assembling the padlock, since the configurations in which a respective padlock can be assembled can then also differ in terms of the type of striker used.

Accordingly, according to an advantageous embodiment, the depth of the first striker receptacle (without the reducing element inserted therein) differs from the depth of the second striker receptacle by an amount which corresponds to the difference in the lengths of the two legs of a striker of a first type, the reducing element is configured to reduce the depth of the first striker receptacle such that the reduced depth of the first striker receptacle differs from the depth of the second striker receptacle by an amount equal to the difference in the lengths of the two legs of one striker of a second type.

According to a further advantageous embodiment, the depth of the first striker retainer is greater than the depth of the second striker retainer, the reducing element being designed to reduce the depth of the first striker retainer to the depth of the second striker retainer. Such an embodiment is particularly useful when hasps of a certain type that is intended to be used for the padlock have legs of the same length. In addition, such an embodiment is also advantageous if, in addition to a hasp type that is rigid and has two legs of different lengths, flexible hasps, for example designed as a cable or chain, should also be usable for the padlock.

The padlock system according to the invention for the variable formation of padlocks in various configurations, which differ in terms of the type of lock cylinder used in the respective padlock and optionally also in terms of the type of in the Distinguish the respective padlock used hasp, comprises at least one padlock basic kit according to one of the preceding claims and at least one lock cylinder of a first type and at least one lock cylinder of a second type

The lock cylinder receptacle of the lock body is preferably designed to optionally accommodate the first lock cylinder adapter with a lock cylinder of the first type inserted therein, the second lock cylinder adapter with a lock cylinder of the second type inserted therein, or a lock cylinder of a third type, and the padlock system also includes at least one lock cylinder of the third type.

Using such a padlock system, a padlock can then be assembled in a desired configuration, in particular with a lock cylinder of a desired type, by the following steps: selecting a lock cylinder of the desired type; if it is a lock cylinder of the first type, inserting the selected lock cylinder into the receiving channel of the first lock cylinder adapter and inserting the first lock cylinder adapter into the lock cylinder receptacle of the lock body; if it is a lock cylinder of the second type, inserting the selected lock cylinder into the receiving channel of the second lock cylinder adapter and inserting the second lock cylinder adapter into the lock cylinder receptacle of the lock body; if lock cylinders of said third type are also provided and it is a lock cylinder of the third type, inserting the selected lock cylinder directly (i.e. without a lock cylinder adapter) into the lock cylinder receptacle of the lock body; and closing the lock cylinder receptacle by means of the closing plate.

According to an advantageous embodiment, it is further provided that the padlock basic kit is designed according to one of the mentioned embodiments, in which the basic kit includes a reducing element for reducing the depth of a hasp receptacle, and the padlock system also has at least one hasp of a first type and at least one hasp of a second type. With such a padlock system, either a hasp of the first type or a hasp of the second type can be used to assemble the padlock, so that together with the two, preferably three, possible lock cylinder types, there are already four, preferably six, different configurations , in which the padlock can be assembled. Preferably, the strikers of the first and the second type each have a U-shape with two legs, the legs of the striker of the first type have different lengths from each other and the legs of the striker of the second type have the same length.

The padlock system according to the invention preferably includes all components that are required for assembling a padlock in the various configurations. Not all components are used in every configuration. In particular, although the system includes locking cylinders of different types, only one locking cylinder of the respectively desired type is used for a respective padlock. Similarly, while the system may include different types of strikers, only one striker of the desired type is used for each padlock. Depending on the type of locking cylinder used, it may then be necessary to use one of the various locking cylinder adapters. In addition, the rotary bolt used can be selected from a number of different rotary bolts depending on the type of lock cylinder used. And depending on the type of hasp used, the use of the reducer may be appropriate. However, some elements of the padlock system, in particular the padlock basic kit, are used in every configuration, namely in particular the lock body and the locking plate, which ensure a uniform appearance of the padlock despite different configurations.

The invention is explained in more detail below, merely by way of example, with reference to the figures.

The figures show various padlocks 11, which can be assembled using an exemplary embodiment of a padlock basic kit according to the invention and locking cylinders 13 of different types and hasps 15 of different types or using a padlock system according to the invention, in at least the eight different configurations shown that can be differ in terms of the type of lock cylinder 13 used in the padlock 11 and the type of hasp 15 used in the padlock 11 .

In the first and second configuration shown in Figures 1 and 2A and 2B, respectively, a lock cylinder 13.1 of a first type is used in the padlock 11; in the third and fourth configuration shown in Figures 3 and 4A and 4B, respectively, a lock cylinder 13.2 of a second type is used in the padlock 11; in the fifth and sixth configuration shown in Figures 5 and 6A and 6B, respectively, a lock cylinder 13.3 of a third type is used in the padlock 11; and in the seventh and eighth configurations shown in Figures 7 and 8A and 8B, respectively, a lock cylinder 13.4 of a fourth type is used in the padlock 11. In addition, in the first, third, fifth and seventh configuration shown in FIGS. 1 and 2A, 3 and 4A, 5 and 6A or 7 and 8A, a hasp 15.1 of a first type is used in the padlock 11, whereas in the second, fourth, sixth and eighth configurations shown in Figures 2B, 4B, 6B and 8B respectively, a hasp 15.2 of a second type is used in the padlock 11, respectively.

The numbering of the configurations, like the numbering of the lock cylinder and striker types, is for conceptual distinction only and is not intended to imply any order or other relationship between the numbered items.

In all eight configurations shown in the figures, the padlock 11 has the same lock body 17 and the same locking plate 19 in each case. The lock body 17 is off made of solid metal and has a lock cylinder receptacle 21, which extends along a longitudinal direction L of the lock body 17 or the padlock 11 and serves to accommodate a lock cylinder 13, which can be selected from several lock cylinders of different types. In addition, the lock body 17 has a first striker retainer 23.1 and a second striker retainer 23.2, which extend parallel to the longitudinal direction L into the lock body 17 and each serve to receive a leg 25 of the respective striker 15 used in the padlock 11 , in order thereby to mount the striker 15 on the lock body 17 so as to be displaceable parallel to the longitudinal direction L. The lock cylinder receptacle 21 and the striker receptacles 23 as well as the overall internal structure of the lock body 17 can be understood in particular in the sectional three-dimensional representation of the lock body 17 in FIGS. 1, 3, 5 and 7.

The lock cylinder receptacle 21 on the one hand and the striker receptacles 23 on the other extend from opposite sides into the lock body 17. The two striker receptacles 23 are arranged transversely to the longitudinal direction L in opposite edge regions of the lock body 17. The first striker receptacle 23.1 has a greater depth than the second striker receptacle 23.2, since the first striker receptacle 23.1 extends deeper into the lock body 17 from the same longitudinally facing outside of the lock body 17 than the second striker receptacle 23.2. The lock cylinder receptacle 21 is partially arranged in a central area of the lock body 17 located between the two edge areas and also partially extends into those of the two named edge areas in which the second striker retainer 23.2 is arranged, which is possible because the lock cylinder - Receptacle 21 with respect to the longitudinal direction L overlaps with the first striker receptacle 23.1, but not with the second striker receptacle 23.2.

When the padlock 11 is assembled, one of the lock cylinders 13 included in the padlock basic kit is accommodated in the lock cylinder receptacle 21 . The locking cylinders are referred to below as locking cylinders 13.1 of a first type, locking cylinders 13.2 of a second type, locking cylinders 13.3 of a third type and locking cylinders 13.4 of a fourth type is to be understood as limiting to the types of lock cylinders mentioned above. . In particular, the numbering of the lock cylinder types shown in the figures is essentially arbitrary and could also be different. In other words, for example, the lock cylinder 13.2 shown in FIGS. 3, 4A and 4B could also be used as a lock cylinder. linders of a first type and/or the lock cylinder 13.4 shown in Figs. 7, 8A and 8B as a lock cylinder of a second type, etc. Only the designation of the lock cylinder 13.3 of the third type can in any case seem fixed insofar as a lock cylinder of this Type without lock cylinder adapter 33 in the lock cylinder receptacle 21 of the lock body 17 can be used. In principle, the figures could also show another lock cylinder of another type, then the fifth type if the numbering is consecutive, which can also be inserted into the lock cylinder receptacle 21 of the lock body 17 without a lock cylinder adapter 33, in which case it would then be conceivable, for example, to use this further lock cylinder as a lock cylinder of the third type and instead to consider the lock cylinder 13.3 of the third type as a lock cylinder of a fifth type.

In the first and the second configuration (FIGS. 1, 2A and 2B), the lock cylinder is in each case a lock cylinder 13.1 of a first type, which is designed as a so-called profile cylinder. Accordingly, the lock cylinder 13.1 of the first type has a profile that includes a circular cylinder section 27 and a web section 29.1 that protrudes radially from the cylinder section 27 with respect to the center point of the cylinder section 27 and is rounded at its free end, the width of which is less than the diameter of the cylinder section 27 and whose length corresponds to the diameter of the cylinder section 27 substantially. The cylinder core of the lock cylinder 13.1 is accommodated in the area of the lock cylinder 13.1 of the first type corresponding to the cylinder section 27 of the profile, while the area corresponding to the web section 29.1 serves to at least partially accommodate the tumblers of the lock cylinder 13.1.

The third and fourth configurations (FIGS. 3, 4A and 4B) each involve a lock cylinder 13.2 of a second type. In the embodiment shown, lock cylinders of the second type 13.2 have a profile that includes a circular cylinder section 27 and a tumbler section 29.2 with a circular contour that is offset relative to cylinder section 27, so that cylinder section 27 and tumbler section 29.2 together have the shape of two mutually offset and each other partially overlapping circular areas. Similar to the locking cylinder 13.1 of the first type, the cylinder core is accommodated in the area of the locking cylinder 13.2 of the second type corresponding to the cylinder section 27 of the profile, while the area corresponding to the web section 29.2 serves to at least partially accommodate the tumblers.

The fifth and sixth configurations (FIGS. 5, 6A and 6B) each involve a lock cylinder 13.3 of a third type, which is designed as a so-called oval cylinder. Accordingly, the locking cylinder 13.3 of the third type has a profile whose shape corresponds to the convex envelope of two mutually offset circular surfaces which have at least essentially the same diameter. One of the two circular areas can be viewed as a cylinder section 27 corresponding to the locking cylinders 13.1, 13.2 of the first and second type, in which the cylinder core of the locking cylinder 13.3 of the third type is accommodated, while the remaining area serves to hold the tumblers at least partially record.

The seventh and eighth configurations (FIGS. 7, 8A and 8B) each involve a lock cylinder 13.4 of a fourth type, which is similar to the lock cylinder 13.2 of the second type in that this lock cylinder 13.4 also has a circular cylinder section 27 and a tumbler section 29.3 with a circular contour that is offset relative to the cylinder section 27. Apart from different dimensions, in particular along the longitudinal direction L, the lock cylinders 13.2, 13.4 of the second and fourth type differ in particular in that the tumbler section 29.3 has a circumferential expansion 30 on the key side.

A driver section 31, which serves to output a turning of the cylinder core, which is possible by means of a key 32 assigned to the respective lock cylinder 13, to a locking mechanism in order to thereby release or lock the respective striker, is designed as a so-called locking lug in the lock cylinder 13.1 of the first type 13.1. With respect to an axis of rotation parallel to the longitudinal direction L of the cylinder core, it is radially separated from the cylinder core and from the rest of the lock cylinder 13.1. presides. In contrast, the lock cylinder 13.2 of the second type, the lock cylinder 13.3 of the third type and the lock cylinder 13.4 of the fourth type each have a structure as driver section 31 that does not protrude radially with respect to the axis of rotation of the cylinder core, but rather axially on one end face of the respective cylinder core and thereby has the form of an elongate web.

The lock cylinders 13.1, 13.2, 13.4 of the first, second and fourth types cannot be inserted directly into the lock cylinder receptacle 21, since their profile is smaller than the cross section of the lock cylinder receptacle 21 referred to as the receptacle cross section, so that they Lock cylinder recording 21 would not be stored stably. The padlock basic kit or the padlock system therefore includes three lock cylinder adapters 33, each of which has a continuous receiving channel 35 that extends along an insertion direction into the respective lock cylinder adapter 33, and which are designed to fill the space between a Lock cylinder 13.1, 13.2, 13.4 of the first, the second Type or the fourth type and the lock cylinder receptacle 21 of the lock body 17 essentially, in particular transversely to the longitudinal direction L, to fill out (in the sectional views of Figs. 2A, 2B, 4A, 4B, 8A and 8B, the lock cylinder adapters 33 are shown hatched).

The receiving channel 35 of the first lock cylinder adapter 33.1 has a constant receiving cross section which is complementary to the profile of the lock cylinder 13.1. is of the first type, the receiving channel 35 of the second lock cylinder adapter 33.2 has a constant receiving cross-section which is complementary to the profile of the lock cylinder 13.2. is of the second type, and the receiving channel 35 of the third lock cylinder adapter 33.3 has a constant receiving cross-section which is complementary to the profile of the lock cylinder 13.4. is of the fourth type. Thus, the lock cylinders 13.1, 13.2, 13.4 of the first, the second and the fourth type can each be inserted flush into the receiving channel 35 of the corresponding lock cylinder adapter 33.1, 33.2, 33.3. The receiving channel 35 of the third lock cylinder adapter 33.3 is widened on the key side in the area of the tumbler section 29.3, so that it has an undercut 36. In this way, the lock cylinder 13.4 of the fourth type can be accommodated at least essentially flush in the accommodation channel 35 despite the aforementioned peripheral expansion 30.

Since the locking cylinder adapters 33 each have a profile, i.e. an outer cross section, which corresponds to the receiving cross section of the locking cylinder receptacle 21 of the lock body 17, the first locking cylinder adapter 33.1 with the locking cylinder 13.1 of the first type inserted therein can then the second lock cylinder adapter 33.2 with the lock cylinder 13.2 of the second type inserted therein or the third lock cylinder adapter 33.3 with the lock cylinder 13.4 of the fourth type inserted therein are inserted flush into the lock cylinder receptacle 21 (cf. in particular the sectional views of Fig. 2A, 2B, 4A, 4B, 8A and 8B).

For lock cylinders 13.3 of the third type, on the other hand, no lock cylinder adapter 33 is required, since the lock cylinder receptacle 21 has a constant receptacle cross section that is complementary to the profile of a lock cylinder 13.3 of the third type, so that the lock cylinder 13.3 of the third type is directly flush in the lock cylinder receptacle 21 can be used (cf. in particular the sectional views of FIGS. 6A and 6B).

Said locking mechanism for locking the legs 25 of a respective striker 15 in the striker receptacles 23 includes two locking balls designed as locking elements 37, which are part of the padlock basic kit or the padlock systems are. The locking elements 27 are mounted in the lock body 17 so that they can be displaced transversely to the longitudinal direction L and can be moved into a respective locking bar position, which is shown in FIGS. 2A, 2B, 4A, 4B, 6A, 6B, 8A and 8B. Receptacles 23 (one locking element 37 in one striker receptacle 23 and the other in the other) protrude in order to engage there in a recess 38 of the respective leg 25 of the striker 15 and thereby prevent the striker 15 from leaving its position shown in the figures to lock the closed position shown.

In order that a rotation output by the driver section 31 of the respective lock cylinder 13 can be used to force the locking elements 37 into their locking position and then to lock them therein or to release them for leaving the locking position for unlocking the striker 15, the locking mechanism also includes a rotating bolt 39 , which is rotatable about an axis of rotation D in a rotating bolt receptacle 41 of the lock body 17, which adjoins the lock cylinder receptacle 21 in the longitudinal direction L, but has a smaller cross section and is in particular arranged exclusively in the central region of the lock body 17 mentioned. The rotating bolt 39 is arranged in such a way that its axis of rotation D is coaxial with the axis of rotation of the cylinder core of the respective lock cylinder 13 .

So that the bolt mechanism can be driven by the different driver sections 31 of the lock cylinder 13 of different types, the padlock basic kit or the padlock system comprises a first rotary bolt 39.1, a second rotary bolt 39.2 and a third rotary bolt 39.3.

The first rotary latch 39.1 is designed to be rotationally coupled to the driver section 31 of the lock cylinder 13.1 of the first type and to partially encompass an end section of the lock cylinder 13.1 in the direction of rotation about the axis of rotation of its cylinder core. In particular, the rotating bolt 39.1 is designed to be slipped onto the end section of the locking cylinder 13.1 in a radial direction with respect to the axis of rotation of the cylinder core of the locking cylinder 13.1 of the first type (cf. FIG. 1).

The second rotary bolt 39.2 and the third rotary bolt 39.3, on the other hand, are designed to be rotationally coupled to the mutually similar driver sections 31 of the lock cylinders 13.2, 13.3, 13.4 of the second, third and fourth types, and for this purpose have a to the web-shaped driver section 31 of the respective lock cylinder 13 complementary groove, in which the driver section 31 can engage axially (see. Fig. 4A, 4B, 6A, 6B, 8A and 8B). The second rotating bolt 39.2 and the third Turnbuckles 39.3 differ from one another in particular with regard to their length and in that the second turnbuckle 39.2 has a circumferential expansion in the area of the front side mentioned, while the third turnbuckle 39.3 has an at least essentially circular cross section with a constant diameter.

All three rotary latches 39 each have a control section 43 which is at least essentially cylindrical in shape, on the outer circumference of which two recesses 45 diametrically opposed with respect to the axis of rotation D are formed, as a result of which a control link is formed for the locking elements 37, which the locking elements 37 depending on the rotational position of the rotating bolt 39, forces it into a locking position in which it locks the striker 15 against leaving the closed position, or releases it for radial movement.

The recesses 45 mentioned each have the shape of a spherical shell in the case of the first rotating bolt 39.1. On the other hand, in the case of the second rotary bolt 39.2 and the third rotary bolt 39.3, the recesses 45 each have the shape of a cylinder jacket segment. This has the advantage that the second rotary bolt 39.2 (like the third rotary bolt 39.3) is not fixed in a precise axial position with respect to the longitudinal direction L relative to the locking ball locking elements 37 and is therefore connected to the locking cylinder

13.2 of the second type as well as with the slightly longer lock cylinder in comparison

13.3 of the third type can be used. To ensure that the second rotating bolt 39.2 does not have too much axial play when used with the shorter lock cylinder 13.2 of the second type and cannot get out of engagement with the driver section 31 of the lock cylinder 13.2, the padlock basic kit or the padlock system also includes a spacer element 47, which has the shape of a circular disc, the diameter of which corresponds to the diameter of the control section 43 (see Figs. 3, 4A and 4B). In this way, by means of the spacer element 47, the second rotating bolt 39.2 can be lengthened, so to speak, and the shorter length of the lock cylinder 13.2 of the second type can be compensated for in comparison to the lock cylinder 13.3 of the third type.

So that the lock cylinder 13 can be easily inserted into the lock cylinder receptacle 21 but is then reliably secured therein and largely protected against access, the lock cylinder receptacle 21 is closed by the closure plate 19 mentioned. For this purpose, the closure plate 19 has a projection 49 with which it engages in an undercut 51 which is formed in a side wall of the lock cylinder receptacle 21 in the area of the opening of the lock cylinder receptacle 21 to the outside. the back Intersection 51 is arranged in that edge area of the lock body 17 in which the second striker receptacle 23.2 is also located.

The projection 49 is beveled so that the locking plate 19 can be inserted into the undercut 51 at an angle with respect to the longitudinal direction L and then pivoted around the region of engagement in the undercut 51 such that it closes the lock cylinder receptacle 21 perpendicular to the longitudinal direction L and essentially flush with the outside of the lock body 17 .

On the side opposite the projection 49 , the closure plate 19 has a threaded bore 53 which, when the closure plate 19 closes the lock cylinder receptacle 21 , is aligned with a screw channel 55 formed in the lock body 17 . The screw channel 55 extends in that edge area of the lock body 17 in which the first striker mount 23.1 is also located, transversely to the longitudinal direction L from the outside into the lock body 17 and ends in the lock cylinder mount 21. This allows a screw 57 in the form of a threaded pin can be screwed through the screw channel 55 into the threaded hole 53 of the closure plate and thereby partially engage in the screw channel 55 so that it locks the closure plate 19 as a result. The lock cylinder receptacle 21 closed by the closure plate 19 can then only be opened again once the screw 57 has been unscrewed from the threaded bore 53 again.

In order to ensure that the screw 57 cannot be unscrewed when the padlock 11 is locked, the lock body 17 has a locking channel 59, which runs parallel to the longitudinal direction L from the first striker retainer 23.1 to the screw channel 55 extends and in which a locking element 61 can be used in the form of a bolt. When the blocking element 61 is inserted into the blocking channel 59, at least part of the blocking element 61 also engages in the screw channel 55 and thereby blocks access to the screw 57 from the outside.

In order to be able to unscrew the screw 57, the blocking element 61 must first be removed from the blocking channel 59. However, since the blocking element 61 has essentially the same length as the blocking channel 59, the blocking element 61 cannot be moved out of the blocking channel 59 as long as a leg 25 of the respective striker 15 is received in the first striker retainer 23.1 and extends down to the ground of the striker retainer 23.1, into which the locking channel 59 opens. In this way, unlocking the locking plate 19 is subject to the condition that the slope lock 11 is unlocked and the leg 25 of the respective striker 15 can consequently be removed from the first striker receptacle 23.1.

In order to be able to easily move the blocking element 61 at least far enough so that it no longer blocks access to the screw 57 when the first striker retainer 23.1 is free, a passage 63 is provided between the blocking channel 59 and the outside of the lock body 17, from which the lock cylinder receptacle 21 extends into the lock body 17 is provided. This passage 63 has a smaller diameter than the blocking channel 59, so that the blocking element 61 cannot pass through it. However, the blocking element 61 can be acted upon from the outside through the passage 63 by means of a correspondingly narrow tool and thus be pressed in the direction of the first striker receptacle 23.1 at least out of the screw channel 55, so that access to the screw 57 is then free.

When the locking plate 19 closes the lock cylinder receptacle 21, it essentially completely covers the respective lock cylinder 13 accommodated therein, i.e. in particular as far as possible without preventing the lock cylinder 13 from being actuated by means of the associated key 32. The locking plate 19 therefore has a key opening 65 through which the respective key 32 can be inserted into the respective lock cylinder 13 inserted into the lock cylinder receptacle 21, with the key opening 65 only being as large as is required for the insertion of the key 32 and for turning the inserted key 32 for locking or unlocking the padlock 11 is absolutely necessary. For this purpose, the key opening 65 has the shape of two circular sectors arranged opposite one another and overlapping one another with their tips, the central angle of which is approximately 65° in each case, which corresponds to the largest of the angles of rotation required for key actuation of the lock cylinders 13 of the first, second and third types.

The padlock 11 can be assembled both in configurations in which it has a hasp 15.1 of the first type and in configurations in which it has a hasp 15.2 of the second type, with the lengths of the two legs 25 of the respective hasp 15 being differ from the striker 15.1 of the first type and are identical in the case of the striker 15.2 of the second type (cf. Fig. 2A, 4A, 6A and 8A on the one hand and Fig. 2B, 4B, 6B and 8B on the other hand). The two striker shots 23 extend so far into the lock body 17 that the depth of the first striker shot 23.1 and the depth of the second striker shot 23.2 differed by an amount which corresponds to the difference in the lengths of the two legs 25 of the lock bush - gels 15.1 of the first type. In this way, when the padlock 11 is closed, both legs 25 of the striker 15.1 of the first type can reach the bottom of the respective striker receptacle 23 (see FIGS. 2A, 4A, 6A and 8A).

However, due to the leg 25 of the second type of striker 15.2 being of the same length, this is not possible in the configurations with this type of striker. If a padlock 11 is locked in a configuration in which it has a striker 15.2 of the second type, a distance therefore remains between the leg 25 of the striker 15.2 accommodated in the first striker receptacle 23.1 and the bottom of the first striker receptacle 23.1. If this distance simply remains free, the locking element 61 accommodated in the locking channel 59 is not secured against being displaced from the screw channel 55 when the padlock 11 is closed, so that it would always be possible to easily gain access to the screw 57.

In order to prevent this, the padlock basic kit or the padlock system includes a reducing element 67 in the form of a bolt whose diameter corresponds to the diameter of the two striker receptacles 23 and which can therefore be inserted into the first striker receptacle 23.1 to reduce their depth. The length of the reducing element 67 corresponds to the difference in the depths of the two striker mounts 23, so that it reduces the depth of the first striker mount 23.1 to the depth of the second striker mount 23.2 (cf. Fig. 2B, 4B, 6B and 8B).

Thus, when the reducing element 67 is inserted, there remains a distance between the leg 25 of the second type of striker 15.2 received in the first striker retainer 23.1 and the bottom of the first striker retainer 23.1, but no free space, so that even in such a configuration of the padlock 1 1 the respective lock cylinder 13 is reliably secured in the lock body 17 via the locking of the locking plate 19 by means of the screw 57 and the blocking element 61 .
