Padlock basic kit and padlock system

Description

[0001] The invention relates to a basic padlock assembly kit for constructing a padlock in a configuration selectable from several options. The configurations from which a particular one can be selected differ with respect to the type of locking cylinder used in the padlock. The basic assembly kit thus allows a specific locking cylinder to be selected from various types and used for assembling a padlock. Consequently, such a basic assembly kit is suitable both for assembling a padlock with a locking cylinder of one specific type and for assembling a padlock with a locking cylinder of a different specific type.Thus, the basic kit is not limited to a single type of locking cylinder, but is versatile, as a padlock with a locking cylinder of the preferred type can be assembled using the same basic kit as needed.

[0002] Furthermore, the configurations can optionally differ with regard to the type of shackle used in the padlock. Such a basic padlock kit thus allows the assembly of either a padlock with a shackle of one specific type or a padlock with a shackle of a different specific type. With such a basic kit, the possible configurations therefore differ in pairs, either with regard to the type of lock cylinder, the type of shackle, or the respective types of both components. It is also possible that the total number of possible configurations for assembling a padlock using the basic kit may differ further with regard to other components, which may be available in various types.The general aim is to enable the creation of a padlock that is as compact as possible in as many different configurations as possible, particularly with regard to the locking cylinders that can be used in the padlock, using the basic padlock kit, while at the same time offering the highest possible level of security, for example at least meeting the requirements of class CEN 5 of DIN EN 12320:2012-12.

[0003] The invention further relates to a padlock system for the variable assembly of padlocks in different configurations, which differ with respect to the type of locking cylinder used in the respective padlock. In contrast to the basic kit, such a system comprises all the fundamental components necessary to assemble padlocks in the various configurations, including, in particular, locking cylinders of different types. Optionally, the configurations of such a padlock system can also differ, as with the basic padlock kit, with respect to the type of locking shackle used in the respective padlock, whereby the system then also includes locking shackles of different types, unlike the corresponding basic kit.

[0004] Lock cylinders are used in a wide variety of locks. Essentially, the lock cylinder serves to be turned and to transmit this rotation to a bolt mechanism within the respective lock. The lock cylinder is designed to allow rotation only when performed with a key assigned to it. Thus, the lock cylinder ensures that the lock can only be operated with the key, specifically unlocked and, if applicable, locked only with the key. Different lock cylinders have been developed for different types of locks, each specifically adapted to the respective lock and therefore differing in their shape and dimensions, particularly their profile, as well as in the mechanism for releasing or locking the rotation.

[0005] For example, so-called profile cylinders are typically used for door locks. Their profile, i.e., the basic cross-section that is essentially constant along its entire length and perpendicular to the direction in which the key is inserted into the cylinder, is standardized. This profile comprises a circular cylinder section containing the cylinder core, and a web section projecting radially from the center of the cylinder section to receive the tumblers. The width (tangential extent) of this web section is smaller than the diameter of the cylinder section, and its length (radial extent) is approximately equal to the diameter of the cylinder section. However, numerous other types of locking cylinders with a variety of different profiles also exist.

[0006] The basic operating principle of lock cylinders is generally the same. Therefore, it is generally possible to use different types of lock cylinders for a single lock. This has the advantage that the lock can be assembled in various configurations by equipping it with a lock cylinder of a specific type, particularly a specific profile, depending on the desired configuration. The benefit of assembling a lock in different configurations can be, for example, that a particular lock can be offered, for instance, with a lock cylinder that provides standard manipulation resistance, and at other times with a higher-quality lock cylinder that offers improved manipulation resistance.The advantage of being able to use different locking cylinders for the same lock can also be that, depending on the availability of different locking cylinders, one or the other type of locking cylinder can be used for assembling the lock.

[0007] Padlocks, in particular, can be used in a wide variety of ways for very different purposes, and different locking cylinders can be advantageous depending on the application. Therefore, a high degree of variability is especially desirable for padlocks. This variability can consist not only of the padlock being able to be assembled in different configurations, but also, advantageously, of the ability to reconfigure the padlock relatively easily, meaning, in particular, that the locking cylinder installed in the padlock can be replaced with a locking cylinder of a different type.

[0008] If a basic padlock kit is designed to accommodate different types of cylinders, particularly those with different profiles, the challenge arises that each cylinder, despite its different design, must be able to be reliably inserted and secured within the padlock. Specifically, allowing for various configurations must not result in the padlock offering reduced security compared to a conventional padlock in some or all configurations. This could occur, for example, because gaps create more opportunities for tampering with the cylinder, or because a less secure fastening makes it easier to remove the cylinder from the padlock.

[0009] Padlock basic kits with the features of the preamble of claim 1 are known, for example, from WO 2020 / 173986 A1 and WO 01 / 65036 A1. Another similar padlock basic kit is described in EP 2 868 850 A1.

[0010] 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 a reliable and secure assembly of the padlock.

[0011] The problem is solved by a padlock basic kit with the features of claim 1 and by a padlock system with the features of claim 14. Advantageous embodiments are described in the dependent claims, the present description and the figures.

[0012] The padlock basic kit according to the invention for assembling a padlock in a configuration selectable from several options, wherein the configurations differ with respect to the type of locking cylinder used in the padlock and optionally also with respect to the type of locking shackle used in the padlock, comprises a lock body, at least two different locking cylinder adapters, and a locking plate. The different types of locking cylinders differ in particular at least with respect to their respective profiles, i.e., their cross-section transverse to a key insertion direction in which a key associated with the respective locking cylinder can be inserted into the locking cylinder. The cross-section can, in particular, be constant at least substantially over the entire length (extension in the key insertion direction) of the locking cylinder.Preferably, no section of the lock cylinder extends beyond the cross-section transversely to the key insertion direction. In this case, the profile corresponds to the outer contour of the lock cylinder when viewed parallel to the key insertion direction.

[0013] One of the at least two lock cylinder adapters has a receiving channel designed to accept a lock cylinder of a first type, and a second of the at least two lock cylinder adapters has a receiving channel designed to accept a lock cylinder of a second type. The basic padlock kit may also include further lock cylinder adapters, each with a receiving channel designed to accept a lock cylinder of a further type.

[0014] The fact that the receiving channels are each designed to accommodate a locking cylinder of a particular type preferably includes ensuring that the locking cylinder fits precisely into the receiving channel, in particular such that, after being received, it rests at least substantially flush against the receiving channel. The receiving channels of the locking cylinder adapters can, in particular, each be continuous, i.e., extending from one outer surface of the respective adapter to the opposite outer surface. Preferably, the receiving channels also each have, at least in certain areas, a constant cross-section transverse to the direction of their extension in or through the respective adapter.

[0015] Furthermore, the lock body features a cylinder receptacle extending longitudinally into the lock body. This receptacle is designed to accommodate either the first cylinder adapter with a cylinder of the first type inserted therein (i.e., received in the receiving channel of the first cylinder adapter), or the second cylinder adapter with a cylinder of the second type inserted therein (i.e., received in the receiving channel of the second cylinder adapter), or a cylinder of a third type. Unlike the use of a cylinder of the first or second type, the cylinder of the third type is received directly into the cylinder receptacle of the lock body, without being inserted into a cylinder adapter that is itself received into the cylinder receptacle.As with the receiving channels, the design of the lock cylinder receptacle for receiving a lock cylinder of the third type includes, preferably, that the lock cylinder fits exactly into the lock cylinder receptacle, in particular in such a way that, after receiving, it lies at least substantially flush with the lock cylinder receptacle.

[0016] The cylinder receptacle can extend, for example, from an end face of the lock body, corresponding to the side of the padlock being assembled where the key is inserted into the respective cylinder, into the lock body. Preferably, the cylinder receptacle does not extend through the lock body, but terminates within the lock body, and may also open into another cavity of the lock body, e.g., a rotary bolt receptacle for receiving a rotary bolt that interacts with the cylinder.

[0017] The aforementioned design of the lock cylinder receptacle of the lock body relative to the at least two cylinder adapters for cylinders of the first and second types, as well as to the cylinder of the third type, allows the basic kit to be used without being limited to a specific type of cylinder. Instead, either a cylinder of the first or second type with the corresponding cylinder adapter, or a cylinder of the third type without a cylinder adapter, can be inserted into the cylinder receptacle. Thus, using the basic kit according to the invention, a padlock can be assembled in at least three different configurations, differing in the type of cylinder used in the padlock, requiring only two different cylinder adapters. The desired configuration can be freely selected. For example,The type of locking cylinder used for the padlock to be assembled can be selected depending on the desired security level for the padlock.

[0018] According to the invention, it is further provided that the closing plate is designed to close the lock cylinder receptacle in such a way that it essentially completely conceals each lock cylinder received in the lock cylinder receptacle (depending on its type with or without a lock cylinder adapter), in particular apart from a key opening formed in the closing plate for inserting a key into the respective lock cylinder.

[0019] The cover plate can completely conceal the lock cylinder received in the lock cylinder receptacle, in particular insofar as the lock cylinder is completely within an outer contour of the cover plate when projected parallel to the aforementioned longitudinal direction, regardless of the type of lock cylinder.

[0020] The locking plate can, for example, be made of hardened metal. The locking cylinder receptacle is preferably closed by attaching the locking plate in an opening area of ​​the locking cylinder receptacle. This opening area can, in particular, be directly adjacent to the aforementioned end face from which the locking cylinder receptacle extends into the lock body.

[0021] By closing the cylinder receptacle, the locking plate (separate from the cylinders and cylinder adapters) not only securely holds the respective cylinder, including any corresponding cylinder adapter, in the receptacle, but also prevents external access to the cylinder – except, if necessary, for accessing a keyway in the cylinder core. In this way, the padlock assembled using the basic kit can exhibit a particularly secure and reliable assembly despite the variability of the cylinder used.

[0022] According to an advantageous embodiment, the receiving channel of the first locking cylinder adapter extends along an insertion direction into the first locking cylinder adapter and has, at least in some areas, a constant receiving cross-section that is complementary to the profile of a locking cylinder of the first type (so that a locking cylinder of the first type can be inserted into the receiving channel of the first locking cylinder adapter in the insertion direction), and the receiving channel of the second locking cylinder adapter extends along an insertion direction into the second locking cylinder adapter and has, at least in some areas, a constant receiving cross-section that is complementary to the profile of a locking cylinder of the second type (so that a locking cylinder of the second type can be inserted into the receiving channel of the second locking cylinder adapter in the insertion direction).wherein the cylinder receptacle of the lock body has a constant receiving cross-section at least in some areas with respect to the longitudinal direction, and wherein the at least two cylinder adapters each have a profile that is complementary to the receiving cross-section of the cylinder receptacle of the lock body (so that optionally one of the at least two cylinder adapters with a cylinder of the first or second type inserted therein can be inserted into the cylinder receptacle, in particular with an insertion direction aligned parallel to the longitudinal direction of the lock body).

[0023] Furthermore, the receiving cross-section of the lock cylinder receptacle in the lock body is preferably complementary to the profile of a third-type lock cylinder. In this case, the profiles of the two lock cylinder adapters correspond to the profile of a third-type lock cylinder.

[0024] The specified receiving cross-sections each limit the maximum cross-section that an object can have when inserted into the receiving channel of the respective cylinder adapter or into the cylinder receptacle of the lock body, either in the insertion direction or longitudinal direction. The receiving cross-sections of the receiving channels of the cylinder adapters refer to the insertion direction of the respective adapter, while the receiving cross-section of the cylinder receptacle of the lock body refers to the longitudinal direction.

[0025] The cross-sectional areas of the receiving channels for the cylinder adapters and the receiving cross-section of the cylinder receptacle in the lock body do not necessarily have to be constant throughout, but may only be constant in certain areas, particularly insofar as the cross-section may be enlarged in other areas, for example, to form an undercut. Furthermore, cavities deeper within the lock body and adjacent to the cylinder receptacle may also have narrower cross-sections; however, such areas are disregarded because they do not serve to receive a cylinder or cylinder adapter and are therefore not part of the cylinder receptacle.

[0026] The aforementioned profiles of the locking cylinders or locking cylinder adapters each correspond to an outer cross-section of the respective locking cylinder, in particular a cylinder housing of the respective locking cylinder, or to an outer cross-section of the respective locking cylinder adapter perpendicular to the direction in which a key can be inserted into the locking cylinder or a locking cylinder can be inserted into the locking cylinder adapter. In particular, all locking cylinders of the same type have the same profile, while locking cylinders of different types have different profiles.

[0027] Due to the aforementioned complementary design of each receiving cross-section to its respective profile, the profile and the receiving cross-section lie flush against each other when installed, thus ensuring a secure and stable fit of the respective locking cylinder or locking cylinder adapter within the respective locking cylinder adapter or the lock body. Certain tolerances may be incorporated, such as a clearance fit, which facilitates insertion or replacement. Alternatively, a transition fit may be provided for a tighter fit. If easy interchangeability is not required, an interference fit is also a viable option, at least in principle.

[0028] According to an advantageous embodiment, locking cylinders of a given type, particularly, for example, of the aforementioned first type, have a profile comprising a circular cylinder section and a web section projecting radially from the cylinder section's center point, preferably rounded at its free end, the width (tangential extent) of which is less than the diameter of the cylinder section's circular shape, and the length (radial extent) which corresponds at least substantially, preferably to a maximum of one millimeter, to the diameter of the cylinder section. Preferably, all locking cylinders of this type have the same profile. In particular, the locking cylinders of this type can be so-called profile cylinders, e.g., according to the standard DIN EN 1303 / 2005.Accordingly, the diameter of the circular shape of the cylinder section can be, for example, 17 mm, the width of the web section can be, for example, 10 mm, and the length of the web section can be, for example, 16.3 mm, so that the profile has a total extent of, for example, 33.3 mm along the direction in which the web section extends.

[0029] According to an advantageous embodiment, locking cylinders of a particular type, in particular, for example, of the aforementioned second type, have a profile comprising a circular cylinder section and a tumbler section with a circular contour offset from the cylinder section, such that the cylinder section and the tumbler section together form the shape of two offset and partially overlapping circular surfaces. It can be provided, in particular, that the two circular surfaces have at least substantially the same diameter, i.e., except for a few, preferably one, millimeters. Furthermore, the offset between the circular surfaces can be, in particular, less than the diameter of the circular surfaces (or, in the case of different diameters, the larger circular surface), so that the profile has at least substantially the shape of a figure eight. Preferably, all locking cylinders of this type have the same profile.

[0030] According to an advantageous embodiment, locking cylinders of a particular type, in particular, for example, of the aforementioned third type, have a profile whose shape corresponds to the convex hull of two offset circular surfaces, which preferably have at least substantially the same diameter, i.e., to the extent of a few, preferably one, millimeters. Preferably, all locking cylinders of this type have the same profile. In particular, the locking cylinders of this type can be so-called oval cylinders, e.g., according to standard DIN EN 1303 / 2005. Accordingly, the diameter of each of the two circular surfaces can be, for example, 20 mm and the offset of the two circular surfaces from each other can be, for example, 15 mm, so that the profile has a total extent of, for example, 35 mm along the direction of the offset.

[0031] Furthermore, it is preferred if the profiles of at least two types of locking cylinders are designed in the manner described above. It is particularly preferred that the profiles of all three types of locking cylinders are designed in one of the manners described above.

[0032] According to an advantageous embodiment, the basic assembly comprises at least two different rotary bolts, each designed to be rotatably mounted in the lock body around an axis of rotation parallel to the longitudinal direction, in order to lock a locking bar, which is movably mounted on the lock body, against leaving a closed position, depending on the rotational position. A first of the at least two rotary bolts is designed to be rotationally coupled to a drive section of a locking cylinder of at least one of the aforementioned types, and a second of the at least two rotary bolts is designed to be rotationally coupled to a drive section of a locking cylinder of at least another of the aforementioned types. Preferably, at least one of the two rotary bolts is designed to be rotationally coupled to the respective drive section of two different locking cylinder types.

[0033] In such an embodiment, depending on the locking cylinder used, a suitable rotary bolt for rotationally effective coupling with its drive 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 such that its axis of rotation is coaxial with the axis of rotation of a cylinder core of the respective locking cylinder housed in the lock body (depending on the type, with or without a locking cylinder adapter).

[0034] The drive sections of the locking cylinders can each, for example, be a structure projecting axially from the cylinder core with respect to a rotational axis of the cylinder core of the respective locking cylinder, which can be aligned parallel to the aforementioned longitudinal direction. This structure can be brought into coupling engagement with a complementary structure formed on an axial end face of the respective rotary bolt. If a rotary bolt is designed in this way, it can simply abut the locking cylinder axially for rotational coupling. One of the aforementioned structures can, for example, be designed as a rib, while the other can be designed as a groove.

[0035] The drive sections can also be designed as a structure projecting radially with respect to the axis of rotation of the cylinder core of the respective locking cylinder, e.g., in the manner of a so-called locking lug of a profile cylinder. With such a design, it is advantageous if the rotary bolt engages at least one end section of the respective locking cylinder or the respective locking cylinder adapter, with the respective locking cylinder inserted therein, at least partially in the direction of rotation around the axis of rotation. The rotary bolt can therefore be designed to be attached to the aforementioned end section, particularly in the radial direction.

[0036] In particular, the drive section with which the first rotary latch can be coupled in a rotationally effective manner and the drive section with which the second rotary latch can be coupled in a rotationally effective manner may differ.

[0037] Accordingly, in an advantageous embodiment, the first rotary bolt is designed to be rotationally coupled to a drive section of a locking cylinder of at least one of the types mentioned, which is formed by a structure projecting radially from the cylinder core with respect to an axis of rotation of a cylinder core of the respective locking cylinder, and the second rotary bolt is designed to be rotationally coupled to a drive section of a locking cylinder of at least another of the types mentioned, which is formed by a structure projecting axially from the cylinder core with respect to an axis of rotation of a cylinder core of the respective locking cylinder.

[0038] For the aforementioned locking of the respective locking bolt by means of a respective rotary bolt, the rotary bolts do not necessarily have to be designed to interact directly with the locking bolt. Rather, it may be provided that the locking is achieved indirectly, e.g. via one or more locking elements movably mounted radially to the axis of rotation of the rotary bolt within the lock body.

[0039] According to an advantageous embodiment, the basic assembly comprises two locking elements, particularly in the form of locking balls, arranged diametrically opposite to the axis of rotation and mounted for radial movement. Each locking bolt has a control section, which is at least substantially cylindrical and has two recesses on its outer circumference that are diametrically opposed to the axis of rotation. This recess forms a control cam for the locking elements, which, depending on the rotational position of the locking bolt, forces the locking elements into a locking position, in which they lock the locking bar against leaving the closed position, or releases them for radial movement. The locking bolts can, in particular, be designed in the manner of a so-called ball slide.

[0040] According to a further advantageous embodiment, the locking plate has a keyhole for inserting a key through the keyhole into the respective cylinder inserted into the cylinder receptacle of the lock body, wherein the keyhole has at least substantially the shape of two opposing circular sectors with identical central angles. The central angles can, for example, be between 45° and 90°, preferably between 55° and 70°, and particularly around 65°. The centers of the circular sectors need not necessarily coincide. Rather, the circular sectors can overlap each other at their tips by an amount that essentially corresponds to the thickness of the respective key. This creates a butterfly shape.

[0041] The aforementioned design of the keyway allows both the insertion of the key and its rotation through an angle limited by the specified central angle. This central angle is therefore advantageously chosen to correspond to the angle of rotation of the cylinder core required to operate the lock cylinder. The keyway is preferably minimal, meaning it is only as large as absolutely necessary for inserting and rotating the key. In this way, the respective lock cylinder inserted into the lock body is maximally covered by the locking plate and secured against unauthorized external access.

[0042] To attach the locking plate to the lock body so that it can securely close the cylinder receptacle, an undercut can be formed in the cylinder receptacle, particularly in the aforementioned opening area, into which the locking plate can engage with a projection. Inserting the locking plate to close the cylinder receptacle can then involve bringing the projection of the locking plate into engagement with the undercut at an angle to the longitudinal direction and then pivoting the locking plate about a pivot axis defined by this engagement into a position in which it closes the cylinder receptacle perpendicular to the longitudinal direction. To ensure reliable locking in this closed position, the locking plate can subsequently be locked to the lock body, particularly on its side opposite the aforementioned projection.

[0043] According to a further advantageous embodiment, the lock body has a screw channel for a screw by means of which the locking plate, when it closes the cylinder receptacle, can be locked, the screw channel extending transversely to the longitudinal direction into the lock body, and the lock body further having a locking channel for a locking element that opens into the screw channel parallel to the longitudinal direction in order to block access from the outside through the screw channel to the screw by means of the locking element inserted into and engaging in the locking channel. The screw channel and the locking channel each preferably have a straight course.

[0044] The screw channel can extend into the lock body from the outside and open into the cylinder receptacle, allowing the screw to be inserted into the channel from the outside and screwed against or into the locking plate, which is inserted into an opening in the cylinder receptacle, to lock it. The screw can be, for example, a set screw, i.e., a threaded stud. Generally, it may be designed so that the screw is tightened against a side surface of the locking plate only to such an extent that the locking plate is clamped in place by the screw.

[0045] Preferably, however, the locking plate has a recess or undercut into which the screw engages when screwed in, in order to lock the locking plate. The recess can also be designed as a threaded bore into which the screw can be screwed for a particularly secure locking mechanism. If the locking plate has the aforementioned projection for engaging an undercut in the lock cylinder receptacle, the locking plate preferably interacts with the screw on its side opposite this projection. In particular, the aforementioned recess can be formed on the side of the locking plate opposite the projection.

[0046] To prevent the locking plate from being easily disengaged by simply unscrewing the screw, access to the screw from the outside through the screw channel is expediently blocked by a locking element, which is inserted into the locking channel. Since the locking channel opens into the screw channel, which may involve crossing the screw channel, the locking element can be inserted in such a way that it engages within the screw channel, extending at least into or even through it, thus preventing the screw from being removed from the screw channel past the locking element. The locking element is designed, for example, as a locking pin or bolt, preferably at least substantially cylindrical. However, the locking element can also be designed as a plate.The barrier channel advantageously has a cross-section complementary to the cross-section of the barrier element.

[0047] According to an advantageous further development of such an embodiment, the lock body is designed such that the locking element can only be removed from the locking channel via a locking bar receptacle formed in the lock body for receiving a leg of a locking bar used in the padlock. This has the advantage that access to the screw for unlocking the locking plate is only permitted by removing the locking element when the locking bar receptacle is clear and the padlock is therefore not locked. In this way, unlocking the locking plate requires opening the padlock, so that the locking of the locking plate is just as secure as the locking of the padlock as a whole.

[0048] In particular, the locking channel can extend from the shackle receptacle to the screw channel. If the locking channel extends even further, beyond the screw channel, it preferably terminates within the lock body, i.e., before reaching an outer surface of the lock body. However, a passage to the outer surface of the lock body can be provided as an extension of the locking channel, which has a different, in particular (significantly) smaller, cross-section than the locking channel. Such a passage can serve to insert a (narrow) tool, e.g., a needle, by means of which the locking element can be pushed through the passage towards the shackle receptacle until it has at least exited the screw channel.

[0049] The various ways in which the locking plate can be designed and the cylinder receptacle can be closed are also advantageous independently of a padlock basic kit.Therefore, a padlock (not claimed in itself) is generally advantageous, comprising a lock body with a cylinder receptacle for receiving a cylinder and a locking plate designed to close the cylinder receptacle in such a way that it substantially completely conceals a respective cylinder received in the cylinder receptacle, wherein an undercut is formed in the cylinder receptacle, in particular in an opening area of ​​the cylinder receptacle, and the locking plate is designed to engage with a projection in the undercut and to be locked to the lock body, in particular on a side of the locking plate opposite the projection.

[0050] The lock body of the (unclaimed) padlock can have a screw channel for a screw that extends from the outside into the lock body and opens into the cylinder receptacle, so that the screw can be screwed against the strike plate or into an engagement section of the strike plate, e.g., a recess or undercut, to lock the strike plate when it closes the cylinder receptacle. The lock body can also have a locking channel for a locking element that opens into the screw channel, so that by inserting the locking element into the locking channel in such a way that the locking element engages 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 such that the locking element can only be removed from the locking channel via a locking shackle receptacle formed in the lock body, which is designed to receive one leg of a locking shackle used in the padlock. For example, the locking channel can extend from the locking shackle receptacle to the screw channel.

[0051] Furthermore, in the (unclaimed) padlock, the locking plate can have a key opening for inserting a key through the key opening into the respective locking cylinder inserted into the locking cylinder receptacle of the lock body, wherein the key opening has at least essentially the form of two mutually opposite circular sectors with identical central angle.

[0052] Furthermore, the lock body, the locking plate, the screw channel, the screw, the locking channel, the locking element, and / or the shackle receptacle of the (unclaimed) padlock can each be designed in one or more of the ways described above or below for the respective corresponding element of a basic padlock kit. This applies in particular to the shape, the spatial position, and / or the spatial orientation of the respective element.

[0053] According to an advantageous embodiment of the padlock basic kit, the lock body has a first shackle receptacle and a second shackle receptacle extending parallel to the longitudinal direction into the lock body and configured to receive one of two legs of a shackle, respectively. The basic kit includes a reducing element configured to be inserted into the first shackle receptacle to reduce its depth, i.e., its longitudinal extension from the entrance to the bottom of the respective shackle receptacle. The shackle receptacles preferably have identical, in particular circular, cross-sections.

[0054] The shackle receptacles of a padlock are advantageously adapted to the lengths of the two legs of each shackle provided on the padlock. In particular, one leg can be longer than the other, which means that even with a rigid shackle, when the padlock is opened, only one leg emerges from its corresponding shackle receptacle, while the other leg is merely shifted within its corresponding shackle receptacle without completely leaving it. This means that the shackle does not have to completely detach from the lock body to open the padlock.

[0055] Different locking shackles can have legs with different length differences. By including a reducing element as part of the basic padlock kit, the difference in depth between the two locking shackle recesses can be set to two different values ​​(by inserting or omitting the reducing element), corresponding to the length differences of two different locking shackle types. This further expands the variability in padlock assembly already offered by the basic kit, as the possible configurations for assembling a padlock can then also vary depending on the locking shackle type used.

[0056] Accordingly, in an advantageous embodiment, the depth of the first locking bar receptacle (without a reducing element inserted therein) differs from the depth of the second locking bar receptacle by an amount which corresponds to the difference in the lengths of the two legs of a locking bar of a first type, wherein the reducing element is designed to reduce the depth of the first locking bar receptacle such that the reduced depth of the first locking bar receptacle differs from the depth of the second locking bar receptacle by an amount which corresponds to the difference in the lengths of the two legs of a locking bar of a second type.

[0057] According to a further advantageous embodiment, the depth of the first shackle receptacle is greater than the depth of the second shackle receptacle, with the reducing element being designed to reduce the depth of the first shackle receptacle to the depth of the second shackle receptacle. Such an embodiment is particularly advantageous when shackles of a specific type, intended for use with the padlock, have legs of the same length. Furthermore, such an embodiment is also advantageous when, in addition to a rigid shackle type with two legs of different lengths, flexible shackles, for example, designed as cables or chains, are also intended for use with the padlock.

[0058] The padlock system according to the invention for the variable design of padlocks in different configurations, which differ with regard to the type of locking cylinder used in the respective padlock and optionally also with regard to the type of locking shackle used in the respective padlock, comprises at least one padlock basic kit according to one of the preceding claims as well as at least one locking cylinder of a first type, at least one locking cylinder of a second type and at least one locking cylinder of a third type.

[0059] The lock cylinder receptacle of the lock body is designed to optionally accommodate the first lock cylinder adapter with a lock cylinder of the first type inserted therein, or the second lock cylinder adapter with a lock cylinder of the second type inserted therein, or to directly accommodate a lock cylinder of the third type.

[0060] Using such a padlock system, a padlock can then be assembled in a desired configuration, in particular with a cylinder of a desired type, by the following steps: selecting a cylinder of the desired type; if it is a cylinder of the first type, inserting the selected cylinder into the receiving channel of the first cylinder adapter and inserting the first cylinder adapter into the cylinder receptacle of the lock body; if it is a cylinder of the second type, inserting the selected cylinder into the receiving channel of the second cylinder adapter and inserting the second cylinder adapter into the cylinder receptacle of the lock body; if it is a cylinder of the third type, inserting the selected cylinder directly (i.e.,(without cylinder adapter) into the cylinder receptacle of the lock body; and closing the cylinder receptacle using the locking plate.

[0061] According to an advantageous embodiment, the padlock basic kit is further designed according to one of the aforementioned embodiments, in which the basic kit includes a reducing element for reducing the depth of a shackle receptacle, and the padlock system further comprises at least one shackle of a first type and at least one shackle of a second type. With such a padlock system, either a shackle of the first type or a shackle of the second type can be used for assembling the padlock, so that, together with the two, preferably three, possible cylinder types, four, preferably six, different configurations result in which the padlock can be assembled.Preferably, the locking bars of the first and second type each have a U-shape with two legs, wherein the legs of the locking bar of the first type have different lengths and the legs of the locking bar of the second type have the same length.

[0062] The padlock system according to the invention preferably comprises all components required for assembling a padlock in various configurations. Not all components are used in every configuration. In particular, while the system includes different types of locking cylinders, only one cylinder of the desired type is used for each padlock. Similarly, while the system may include different types of locking bolts, only one locking bolt of the desired type is used for each padlock. Depending on the type of locking cylinder used, the use of one of the various locking cylinder adapters may also be necessary. Furthermore, the rotary bolt used can be selected from several different types, depending on the type of locking cylinder used.Depending on the type of locking shackle used, the use of the reducing element may be advantageous. However, some elements of the padlock system, particularly the basic padlock kit, are used in every configuration, namely the lock body and the locking plate, which ensure a uniform appearance of the padlock despite different configurations.

[0063] The invention will be further explained below using the figures as examples only.

Fig. 7 Fig. 8B shows a sectional view of a padlock assembled in an eighth configuration using the same embodiment of a padlock basic kit or padlock system according to the invention, which differs from the seventh configuration with regard to the type of locking shackle used.

[0064] The figures show various padlocks 11 which can be assembled by means of an exemplary embodiment of a padlock basic kit according to the invention, as well as locking cylinders 13 of different types and locking bars 15 of different types, or by means of a padlock system according to the invention, in at least the eight different configurations shown, which differ with regard to the type of locking cylinder 13 used in the padlock 11 and the type of locking bar 15 used in the padlock 11.

[0065] In the first and second configurations, which are in the Fig. 1 and 2A In the padlock 11, a locking cylinder 13.1 of the first type is used; in the third and fourth configurations, which are shown in the Fig. 3 and 4Aor 4B, a locking cylinder 13.2 of a second type is used in the padlock 11; in the fifth and sixth configurations, which are shown in the Fig. 5 and 6A or 6B, a third-type locking cylinder 13.3 is used in each padlock 11; and in the seventh and eighth configurations, which are shown in the Fig. 7 and 8A As shown in Figures 8B, a locking cylinder 13.4 of the fourth type is used in each padlock 11. Furthermore, in the first, third, fifth, and seventh configurations, which are shown in the Fig. 1 and 2A , 3 and 4A , 5 and 6A or 7 and 8A, in the padlock 11 a locking shackle 15.1 of the first type is used in each case, whereas in the second, fourth, sixth and eighth configurations, which are shown in Fig. 2B , 4B , 6Bor 8B, in which a locking shackle 15.2 of a second type is used in each padlock 11.

[0066] The numbering of the configurations, as well as the numbering of the lock cylinder and locking bar types, serves only for conceptual differentiation and is not intended to imply any order or other relationship between the numbered elements.

[0067] In all eight configurations shown in the figures, the padlock 11 has the same lock body 17 and the same locking plate 19. The lock body 17 is made of solid metal and has a cylinder receptacle 21 extending along a longitudinal direction L of the lock body 17 or padlock 11. This receptacle serves to accommodate a cylinder 13, which can be selected from several different types. The lock body 17 also has a first shackle receptacle 23.1 and a second shackle receptacle 23.2 extending parallel to the longitudinal direction L into the lock body 17. Each shackle receptacle serves to receive a leg 25 of the respective shackle 15 used in the padlock 11, thereby allowing the shackle 15 to be mounted on the lock body 17 in a position that is movable parallel to the longitudinal direction L.The cylinder receptacle 21 and the locking bar receptacles 23 as well as the entire internal structure of the lock body 17 are shown in particular in the cutaway three-dimensional representation of the lock body 17 in the . Fig. 1 , 3 , 5 and 7 understandable.

[0068] The cylinder receptacle 21 and the shackle receptacles 23 extend into the lock body 17 from opposite sides. The two shackle receptacles 23 are arranged transversely to the longitudinal direction L in opposite edge regions of the lock body 17. The first shackle receptacle 23.1 has a greater depth than the second shackle receptacle 23.2, since the first shackle receptacle 23.1 extends deeper into the lock body 17 from the same longitudinally oriented outer surface than the second shackle receptacle 23.2. The cylinder receptacle 21 is partially located in a central region of the lock body 17 situated between the two edge regions and also extends partially into the one of the two aforementioned edge regions in which the second shackle receptacle 23.1 is located.2 is arranged, which is possible because the lock cylinder receptacle 21 overlaps with the first locking bar receptacle 23.1 with respect to the longitudinal direction L, but not with the second locking bar receptacle 23.2.

[0069] In the cylinder receptacle 21, one of the cylinders 13 included in the basic padlock kit is held when the padlock 11 is assembled. The cylinders are referred to below as cylinder 13.1 of a first type, cylinder 13.2 of a second type, cylinder 13.3 of a third type, and cylinder 13.4 of a fourth type. This designation serves only for linguistic differentiation and is not to be understood as restricting a specific order, ranking, or assignment to the aforementioned types of cylinders. In particular, the numbering of the cylinder types shown in the figures is essentially arbitrary and could also be different. In other words, for example, the cylinder shown in the figures could also be... Fig. 3 , 4A und 4B The lock cylinder shown 13.2 is to be considered a lock cylinder of the first type and / or the one shown in the Fig. 7 , 8A und 8B The lock cylinder 13.4 shown can be considered a lock cylinder of a second type, etc. Only the designation of the lock cylinder 13.3 of the third type seems to be fixed insofar as a lock cylinder of this type can be inserted into the lock cylinder receptacle 21 of the lock body 17 without a lock cylinder adapter 33. In principle, however, the figures could also show another lock cylinder of a different, fifth type (if numbering continues consecutively), which can also be inserted into the lock cylinder receptacle 21 of the lock body 17 without a lock cylinder adapter 33. In this case, it would be conceivable, for example, to consider 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.

[0070] In the first and second configurations ( Fig. 1 , 2A und 2B The locking cylinder in each case is a locking cylinder 13.1 of the first type, designed as a so-called profile cylinder. Accordingly, the locking cylinder 13.1 of the first type has a profile comprising a circular cylinder section 27 and a web section 29.1 projecting radially from the center point of the cylinder section 27, rounded at its free end, the width of which is less than the diameter of the cylinder section 27 and whose length essentially corresponds to the diameter of the cylinder section 27. The cylinder core of the locking cylinder 13.1 is received in the area of ​​the locking 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 receive the tumblers of the locking cylinder 13.1.

[0071] In the third and fourth configurations ( Fig. 3 , 4A und 4B Each of these is a locking cylinder 13.2 of a second type. In the illustrated embodiment, locking cylinders of the second type 13.2 have a profile comprising a circular cylinder section 27 and a tumbler section 29.2 with a circular contour offset from the cylinder section 27, such that the cylinder section 27 and the tumbler section 29.2 together form the shape of two offset and partially overlapping circular surfaces. Similar to the locking cylinder 13.1 of the first type, the cylinder core is received 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 receive the tumblers.

[0072] In the fifth and sixth configurations ( Fig. 5 , 6A und 6B Each of these is a third-type locking cylinder 13.3, designed as a so-called oval cylinder. Accordingly, the third-type locking cylinder 13.3 has a profile whose shape corresponds to the convex hull of two offset circular surfaces that have at least substantially the same diameter. One of the two circular surfaces can be considered, in accordance with the first and second-type locking cylinders 13.1 and 13.2, as cylinder section 27, in which the cylinder core of the third-type locking cylinder 13.3 is received, while the remaining area serves to at least partially receive the tumblers.

[0073] In the seventh and eighth configurations ( Fig. 7 , 8A und 8B Each of these is a locking cylinder 13.4 of a fourth type, which is similar to the locking cylinder 13.2 of the second type in that this locking cylinder 13.4 also comprises a circular cylinder section 27 and a tumbler section 29.3 with a circular contour offset from the cylinder section 27. Apart from different dimensions, especially along the longitudinal direction L, the locking cylinders 13.2, 13.4 of the second and fourth types differ in particular in that the tumbler section 29.3 has a circumferential extension 30 on the key side.

[0074] A drive section 31, which serves to transmit a rotation of the cylinder core possible by means of a key 32 assigned to the respective locking cylinder 13 to a locking mechanism in order to release or lock the respective locking bolt, is designed in the first-type locking cylinder 13.1 as a so-called locking lug, which projects radially from the cylinder core and from the rest of the locking cylinder 13.1 with respect to an axis of rotation parallel to the longitudinal direction L of the cylinder core. In contrast, the second-type locking cylinder 13.2, the third-type locking cylinder 13.3 and the fourth-type locking cylinder 13.4 each have a drive section 31 that does not project radially with respect to the axis of rotation of the cylinder core, but rather axially from an end face of the respective cylinder core and has the form of an elongated rib.

[0075] The locking cylinders 13.1, 13.2, 13.4 of the first, second, and fourth types cannot be directly inserted into the locking cylinder receptacle 21 because their profile is smaller than the cross-section of the locking cylinder receptacle 21, which is referred to as the receiving cross-section. Therefore, they would not be stably supported in the locking cylinder receptacle 21. Consequently, the basic padlock kit or padlock system comprises three locking cylinder adapters 33, each with a continuous receiving channel 35 extending along an insertion direction into the respective locking cylinder adapter 33. These adapters are designed to substantially fill the gap between a locking cylinder 13.1, 13.2, 13.4 of the first, second, or fourth type and the locking cylinder receptacle 21 of the lock body 17, particularly transversely to the longitudinal direction L (as shown in the sectional views of the Fig. 2A, 2B , 4A, 4B , 8A und 8B (The lock cylinder adapters 33 are shown hatched).

[0076] The receiving channel 35 of the first locking cylinder adapter 33.1 has a constant receiving cross-section that is complementary to the profile of the locking cylinder 13.1 of the first type; the receiving channel 35 of the second locking cylinder adapter 33.2 has a constant receiving cross-section that is complementary to the profile of the locking cylinder 13.2 of the second type; and the receiving channel 35 of the third locking cylinder adapter 33.3 has a constant receiving cross-section that is complementary to the profile of the locking cylinder 13.4 of the fourth type. Thus, the locking cylinders 13.1, 13.2, 13.4 of the first, second, and fourth types can each be inserted flush into the receiving channel 35 of the corresponding locking cylinder adapter 33.1, 33.2, 33.3. The receiving channel 35 of the third locking 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 locking cylinder 13.4 of the fourth type can be received at least essentially flush in the receiving channel 35 despite the aforementioned extension 30.

[0077] Since the cylinder adapters 33 each have a profile, i.e., an outer cross-section, that corresponds to the receiving cross-section of the cylinder receptacle 21 of the lock body 17, the first cylinder adapter 33.1 with the cylinder 13.1 of the first type inserted therein, the second cylinder adapter 33.2 with the cylinder 13.2 of the second type inserted therein, and the third cylinder adapter 33.3 with the cylinder 13.4 of the fourth type inserted therein can subsequently be inserted flush into the cylinder receptacle 21 (see in particular the sectional views of the Fig. 2A, 2B , 4A, 4B , 8A und 8B ).

[0078] For locking cylinders 13.3 of the third type, however, no locking cylinder adapter 33 is required, since the locking cylinder receptacle 21 has a constant receiving cross-section that is complementary to the profile of a locking cylinder 13.3 of the third type, so that the locking cylinder 13.3 of the third type can be inserted directly flush into the locking cylinder receptacle 21 (see in particular the sectional views of the Fig. 6A und 6B ).

[0079] The aforementioned locking mechanism for locking the legs 25 of a respective locking bar 15 in the locking bar receptacles 23 comprises two locking elements 37 designed as locking balls, which are part of the basic padlock kit or the padlock system. The locking elements 27 are mounted transversely to the longitudinal direction L in the lock body 17 and can be in a locking position which is in the Fig. 2A, 2B , 4A, 4B , 6A, 6B , 8A und 8B As shown, the locking elements 37 protrude into each of the locking bar receptacles 23 (one locking bar receptacle 37 into one locking bar receptacle 23 and the other into the other) in order to engage in a recess 38 of the respective leg 25 of the locking bar 15 and thereby lock the locking bar 15 against leaving its closed position shown in the figures.

[0080] In order to utilize the rotation generated by the drive section 31 of the respective locking cylinder 13 to force the locking elements 37 into their locking position and subsequently lock them therein, or to release them from the locking position to unlock the locking bolt 15, the locking mechanism also includes a rotary bolt 39, which is rotatably received about a pivot axis D in a rotary bolt receptacle 41 of the lock body 17. This receptacle adjoins the locking cylinder receptacle 21 in the longitudinal direction L, but has a smaller cross-section and is located exclusively in the aforementioned central region of the lock body 17. The rotary bolt 39 is arranged such that its pivot axis D is coaxial with the pivot axis of the cylinder core of the respective locking cylinder 13.

[0081] In order for the locking mechanism to be driven by the different drive sections 31 of the locking cylinders 13 of different types, the padlock basic kit or padlock system includes a first rotary bolt 39.1, a second rotary bolt 39.2 and a third rotary bolt 39.3.

[0082] The first rotary bolt 39.1 is designed to be rotationally coupled to the drive section 31 of the first-type locking cylinder 13.1 and, for this purpose, to partially engage an end section of the locking cylinder 13.1 in the direction of rotation around the axis of rotation of its cylinder core. In particular, the rotary bolt 39.1 is designed to be placed 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 first-type locking cylinder (see Figure 1). Fig. 1 ).

[0083] 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 similar driver sections 31 of the locking cylinders 13.2, 13.3, 13.4 of the second, third and fourth types, and for this purpose have on one end face a groove complementary to the web-shaped driver section 31 of the respective locking cylinder 13, into which the driver section 31 can engage axially (cf. Fig. 4A, 4B , 6A, 6B , 8A und 8B ). The second rotary latch 39.2 and the third rotary latch 39.3 differ from each other in particular with regard to their length and in that the second rotary latch 39.2 has a circumferential extension in the area of ​​the aforementioned end face, while the third rotary latch 39.3 has an at least substantially circular cross-section with a constant diameter.

[0084] All three rotary latches 39 each have a control section 43 which has an at least substantially cylindrical shape, on the outer circumference of which two recesses diametrically opposed to the axis of rotation D are formed, thereby forming a control cam for the latch elements 37 which forces the latch elements 37 into a locking position depending on the rotational position of the rotary latch 39, in which they lock the locking bar 15 against leaving the closed position, or release it for radial movement.

[0085] The aforementioned recesses 45 in the first rotary bolt 39.1 each have the shape of a spherical shell. In contrast, in the second rotary bolt 39.2 and the third rotary bolt 39.3, the recesses 45 each have the shape of a cylindrical segment. This has the advantage that the second rotary bolt 39.2 (as well as the third rotary bolt 39.3) is not fixed to a precise axial position relative to the locking ball elements 37 with respect to the longitudinal direction L and can therefore be used with both the locking cylinder 13.2 of the second type and the comparatively slightly longer locking cylinder 13.3 of the third type. To prevent the second rotary bolt 39.2 from having excessive axial play when used with the shorter locking cylinder 13.2 of the second type and from disengaging from the drive section 31 of the locking cylinder 13.2, the basic padlock kit includes...the padlock system also includes a spacer element 47, which has the form of a circular disc, the diameter of which corresponds to the diameter of the control section 43 (cf. . Fig. 3 , 4A und 4B ). In this way, the second rotary bolt 39.2 can be extended, so to speak, by means of the spacer element 47, thereby compensating for the shorter length of the locking cylinder 13.2 of the second type compared to the locking cylinder 13.3 of the third type.

[0086] To ensure that the locking cylinders 13 can be easily inserted into the locking cylinder receptacle 21, but are subsequently reliably secured and largely protected from unauthorized access, the locking cylinder receptacle 21 is closed by the aforementioned locking plate 19. For this purpose, the locking plate 19 has a projection 49 that engages in an undercut 51 formed in a side wall of the locking cylinder receptacle 21 in the area of ​​its opening. The undercut 51 is located in the same edge region of the lock body 17 where the second locking bolt receptacle 23.2 is also situated.

[0087] The projection 49 is chamfered so that the locking plate 19 can be inserted obliquely into the undercut 51 with respect to the longitudinal direction L and then pivoted around the area of ​​engagement in the undercut 51 so that it closes the locking cylinder receptacle 21 perpendicular to the longitudinal direction L and is essentially flush with the outside of the lock body 17.

[0088] On the side opposite the projection 49, the locking plate 19 has a threaded bore 53 which, when the locking plate 19 closes the cylinder receptacle 21, aligns with a screw channel 55 formed in the lock body 17. The screw channel 55 extends transversely to the longitudinal direction L from the outside into the lock body 17 in that edge region of the lock body 17 where the first locking bolt receptacle 23.1 is also located, and opens into the cylinder receptacle 21. This allows a screw 57 in the form of a threaded stud to be screwed through the screw channel 55 into the threaded bore 53 of the locking plate and to partially engage in the screw channel 55, thus locking the locking plate 19. The locking cylinder receptacle 21, which is closed by the locking plate 19, can only be opened again once the screw 57 has been unscrewed from the threaded bore 53.

[0089] To ensure that the screw 57 cannot be unscrewed when the padlock 11 is locked, the lock body 17 has a locking channel 59 extending parallel to the longitudinal direction L from the first locking shackle receptacle 23.1 into the screw channel 55, into which a locking element 61 in the form of a bolt can be inserted. When the locking element 61 is inserted into the locking channel 59, at least part of the locking element 61 also engages in the screw channel 55, thus blocking access to the screw 57 from the outside.

[0090] In order to unscrew the screw 57, the locking element 61 must first be removed from the locking channel 59. Since the locking element 61 is essentially the same length as the locking channel 59, it cannot be moved out of the locking channel 59 as long as a leg 25 of the respective locking shackle 15 is engaged in the first locking shackle receptacle 23.1 and extends to the bottom of the locking shackle receptacle 23.1, into which the locking channel 59 opens. Thus, unlocking the locking plate 19 is contingent upon the padlock 11 being unlocked and the leg 25 of the respective locking shackle 15 being removed from the first locking shackle receptacle 23.1.

[0091] To allow the locking element 61 to be easily repositioned, at least to the point where it no longer obstructs access to the screw 57, when the first locking bolt receptacle 23.1 is free, a passage 63 is provided between the locking channel 59 and the outer surface of the lock body 17, from which the cylinder receptacle 21 extends into the lock body 17. This passage 63 has a smaller diameter than the locking channel 59, so that the locking element 61 cannot pass through it. However, the locking element 61 can be actuated from the outside through the passage 63 using a suitably narrow tool and thereby pushed towards the first locking bolt receptacle 23.1 at least as far as the screw channel 55, so that access to the screw 57 is then unobstructed.

[0092] When the locking plate 19 closes the cylinder receptacle 21, it essentially completely conceals the respective cylinder 13 housed therein, i.e., as far as possible, without preventing the cylinder 13 from being operated by the associated key 32. Therefore, the locking plate 19 has a keyhole 65 through which the respective key 32 can be inserted into the respective cylinder 13 inserted into the cylinder receptacle 21. The keyhole 65 is only as large as is absolutely necessary for inserting the key 32 and for turning the inserted key 32 to lock or unlock the padlock 11.The key opening 65 has the form of two circular sectors arranged opposite to each other and overlapping at their tips, the central angle of which is approximately 65°, which corresponds to the largest of the rotation angles required for key operation of the locking cylinders 13 of the first, second and third type.

[0093] The padlock 11 can be assembled in configurations both in which it has a locking shackle 15.1 of the first type and in configurations in which it has a locking shackle 15.2 of the second type, wherein the lengths of the two legs 25 of the respective locking shackle 15 differ in the locking shackle 15.1 of the first type and are identical in the locking shackle 15.2 of the second type (cf. Fig. 2A , 4A , 6A and 8A on the one hand and Fig. 2B , 4B , 6B and 8Bon the other hand). The two shackle receptacles 23 extend into the lock body 17 to such an extent that the depth of the first shackle receptacle 23.1 and the depth of the second shackle receptacle 23.2 differ by an amount corresponding to the difference in length of the two legs 25 of the shackle 15.1 of the first type. In this way, when the padlock 11 is closed, both legs 25 of the shackle 15.1 of the first type can each reach down to the bottom of their respective shackle receptacle 23 (cf. Fig. 2A , 4A , 6A and 8A ).

[0094] However, due to the equal length of the legs 25 of the second-type locking shackle 15.2, this is not possible in configurations with this locking shackle type. Therefore, when a padlock 11 is locked in a configuration with a second-type locking shackle 15.2, a gap remains between the leg 25 of the locking shackle 15.2, which is received in the first locking shackle receptacle 23.1, and the base of the first locking shackle receptacle 23.1. If this gap simply remains open, the locking element 61, which is received 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 easy to gain access to the screw 57.

[0095] To prevent this, the basic padlock kit or padlock system includes a reducing element 67 in the form of a bolt, the diameter of which corresponds to the diameter of the two locking shackle receptacles 23 and which can therefore be inserted into the first locking shackle receptacle 23.1 to reduce its depth. The length of the reducing element 67 corresponds to the difference in depth between the two locking shackle receptacles 23, so that it reduces the depth of the first locking shackle receptacle 23.1 to the depth of the second locking shackle receptacle 23.2 (see Figure 1). Fig. 2B , 4B , 6B and 8B ).

[0096] Thus, when the reducing element 67 is inserted, there remains a gap, but no free space, between the leg 25 of the locking bar 15.2 of the second type, which is received in the first locking bar receptacle 23.1, and the base of the first locking bar receptacle 23.1, so that even in such a configuration of the padlock 11 the respective locking cylinder 13 is reliably secured in the lock body 17 by means of the locking of the locking plate 19 by means of the screw 57 and the locking element 61.
