Abstract

A padlock comprises a lock body, a bracket, which is held displaceably on the lock body, a cylinder core, in which at least one core pin is inserted and which is rotatably mounted directly in a receiving opening of the lock body about a cylinder axis to the bracket either to the lock body lock or release, and a tumbler housing, in which at least one housing pin is inserted and which is received in a fixed position in a further receiving opening of the lock body. The tumbler housing is substantially cylindrical, and / or the further receiving opening is formed as a cylindrical receiving bore.

Description

The present invention relates to a padlock with a lock body and a bracket which is held displaceably on the lock body and can be optionally locked or released on the lock body, according to the preamble of claim 1. Such a padlock is also in EP 0 605 932 A2 described.

The bracket of such a padlock is typically U-shaped with two stirrup legs and can be displaced between a closed position in which both stirrup legs are inserted into the lock body and an open position in which one of the stirrup legs is still held in the lock body while the other emerges from the lock body.

In order to lock the bracket in the closed position on the lock body, so to lock against displacement in the open position, a locking device may be provided in the lock body, which are actuated by a lock cylinder and secured in this manner against unauthorized opening of the padlock , Only by means of a key associated with the lock cylinder, the padlock can then be opened regularly.

Typically, the lock cylinder comprises a cylinder housing with a hollow cylindrical core receiving portion in which a cylinder core is rotatably mounted about a cylinder axis, and with an integrally formed on the core receiving portion eccentric web portion, wherein in the two sections a plurality of pin tumblers are provided. These pin tumblers each include a core-side core pin and a barrel-side case pin coaxially aligned flush with each other, and a pin spring which supports the case pin and biases the core pin in the direction of the cylinder core. Only when a suitable key is inserted into a key receptacle of the cylinder core, the pin tumblers are axially displaced against the bias that the respective interface between the core pin and housing pin is arranged in the transition between the cylinder core and cylinder housing, so that the cylinder core can be rotated in the cylinder housing to open the padlock. Otherwise, the cylinder core is locked by the pin tumblers against rotation in the cylinder housing.

Such padlocks are for example from the documents DE 10 2009 023 561 A1 and the DE 10 2011 009 591 A1 known and are due to their high quality and safety comparatively high priced.

In such padlocks, the lock body before assembly with the other parts of the padlock (especially before the onset of the lock cylinder) can be dyed without much effort or refined in any other way.

Colored padlocks are used, for example, to identify and easily identify various padlocks. In recent years, moreover, the importance of colored padlocks has increased as a result of the widespread custom of fixing padlocks as so-called "love locks" on bridge railings or other special places. Here and in other areas, the color of an individualization and embellishment of the appearance of a padlock.

A refinement of the lock body can serve not only the visual, but also the qualitative enhancement of the padlock by giving the padlock advantageous properties. Thus, a refinement, such as, for example, galvanizing, chromating and / or phosphating the lock body, serve as corrosion protection. By refining, furthermore, the hardness and / or the feel of the surface of the lock body can be modified in a targeted manner. In particular, the lock body can be both dyed and finished in another way, wherein the dyeing and finishing can be done simultaneously by a single method, for example by anodizing, through which a surface can be colored at the same time and corrosion resistant. If the lock body is finished by attaching a corrosion protection, relatively inexpensive materials can be used for the manufacture of the lock body, which can also be machined well.

In order to produce padlocks cost-effective, but may alternatively be provided to the design with inserted lock cylinder that is dispensed with a cylinder housing and that the functions of the cylinder housing, namely to store the cylinder core rotatably and to receive the housing pins, are realized directly in the lock body. Such a padlock is in AU 2006230686 A1 and CN 202 139 932 U disclosed. In the absence of a cylinder housing are in such a padlock directly in the lock body itself designed as holes pin channels for inserting the housing pins provided while the corresponding pin channels for the core pins are still provided in the cylinder core. The pin channels are drilled from the outside into the lock body so that they are accessible to the pin tumblers from the outside. In the case of a lock body and a cylinder core made of a good material to be machined as brass, the pin channels can advantageously be drilled from the outside through the lock body and into the cylinder core into it.

Brass also has the advantage that it has very good corrosion properties. Brass is relatively expensive. Therefore, if the comparatively high cost of brass is to be avoided, alternative materials may also be used be like brass allow bores over long distances. Due to the higher susceptibility to corrosion of such materials, however, the application of additional corrosion protection is required.

In the illustrated construction without a cylinder housing, that is, when the rotatable cylinder core is mounted directly in the lock body, said pin channels must be reliably closed after the onset of Stiftzuhaltungen to the outside, so that the security of the castle is not compromised. For this purpose, the pin channels can be closed with closure means, such as with brass plugs (for example, in padlocks with a lock body made of brass or other metal) or with another material. In such embodiments, it is necessary after closing the pin channels to secure the closure means against loosening and ideally to make unrecognizable, in order to offer no points of attack for manipulation of the padlock and in particular not to affect the corrosion resistance of the padlock. In this case, the transitions between the closure means and the lock body, for example, grinded and / or reworked in some other way (especially post-processed).

However, such reworking in connection with colored and / or differently finished padlocks is problematic because it is not or only with uneconomical effort possible to perform said, for safe and optically seamless closure of the pin channels reworking such that one before assembly the padlock was staining and / or finishing the lock body is not affected. Such a deterioration can result, for example, from the fact that a surface coloration or a corrosion protection layer is removed locally as a result of wear or that a color appears optically different on the lock body and the closure means, for example if the lock body and the closure means consist of different materials.

A cost-effective way to make a color or other refinement of the lock body only after the assembly of the padlock or to fix a local existing impairment, as explained above, in an optically inconspicuous manner, is not known.

A problem is thus to produce a padlock of the type mentioned on the one hand cost, by no complete (ie separately functional) lock cylinder is required and the lock body can be used a material that is sufficiently good to work, but cheaper than brass, and on the other the lock body prior to assembly of the padlock nevertheless with a uniform and consistent color and / or other finishing (especially with a corrosion protection layer) to be able to provide.

It is therefore an object to provide a padlock, which have a colored and / or finished lock body and can be manufactured inexpensively in a simple manner.

The object is achieved by a padlock with the features of claim 1.

The padlock comprises a cylinder core into which at least one core pin is inserted and which is rotatably mounted directly in a receiving opening of the lock body about a cylinder axis to selectively lock or unlock the bracket to the lock body. The padlock further comprises a tumbler housing, in which at least one housing pin is inserted and which is received fixed in position in the lock body.

It is on the one hand essential that the cylinder core is rotatably mounted directly in a receiving opening of the lock body. The padlock is therefore zylindergehäuselos. A core receiving portion, as explained in the prior art, does not exist. The cylinder core is supported directly by the lock body. In this case, for example, an outer circumferential surface of the cylinder core abut directly on an inner circumferential surface of the receiving opening, wherein in particular during a rotational movement of the cylinder core, the lateral surface of the cylinder core is slidably guided on the lateral surface of the receiving opening. Preferably, the cylinder core is at least substantially over its entire longitudinal extension in the direction of the cylinder axis away at the receiving opening. In this way, the cylinder core can be reliably rotated about its cylinder axis relative to the lock body, without a cylinder housing would be provided.

On the other hand, a separate from the lock body or own tumbler housing is provided for the function to receive the at least one pin tumbler, which is arranged fixed in position in the particular solid lock body. The tumbler housing is thus arranged relative to the lock body in particular against rotation and axially secured. The function of receiving respective pin tumblers is thus not taken over by the lock body in the case of the padlock according to the invention, as is the bearing of the cylinder core. In particular, in the tumbler housing one or more Stiftzuhaltungskanäle, about in the form of Stiftzuhaltungsbohrungen provided, in which the housing pins are inserted. In addition, they can record the pen spring of a respective pin tumbler. The lock body, however, is free of Stiftzuhaltungskanälen or Stiftzuhaltungsbohrungen. As well as in the entire description, the term "bore" is to be understood in each case geometrically and independently of a respective manufacturing process. A bore in a body thus has a geometry as may arise by drilling, but may also be formed by casting the body or otherwise.

In particular, a respective core pin inserted into the cylinder core is associated with a respective housing pin inserted into the tumbler housing, which then together with a respective pin spring form a pin tumbler of the padlock. In order for the interaction of the core pin and the housing pin between the cylinder core and the tumbler housing to lock or unlock a rotation of the cylinder core relative to the tumbler housing (or the lock body), it is provided in particular that the cylinder core and the tumbler housing adjacent to each other and / or adjacent to each other are arranged. However, the tumbler does not completely surround the cylinder core in the manner of a cylinder housing. Rather, the cylinder core adjoins with a large part of its circumference directly to the lock body, while only a smaller part directly adjacent to the tumbler housing.

Typically, a padlock, the locking mechanism of which includes pin tumblers for locking the cylinder core, has a plurality of pin tumblers to allow a variety of different codings for different keys. But it is also conceivable to provide a locking mechanism which has only a single pin tumbler, for example, if the locking mechanism further tumblers of other kind, such as platelet and / or Scheibenzuhaltungen includes, and thus different types of tumblers are combined in a castle.

Compared to a conventional cylinder housing, the tumbler housing can be made particularly simple and inexpensive. This is due in particular to the fact that the tumbler housing advantageously does not need to have a receiving opening for the rotatable mounting of the cylinder core. The decoupling of the two functions, which usually exerts a cylinder housing, namely the storage of the cylinder core and the inclusion of respective pin tumblers, and the distribution of these functions on the lock body on the one hand and on a Instead of a cylinder housing provided tumbler housing on the other hand thus allows a particularly economical production of the padlock, without causing the lock body would be injured by pin channels for each pin tumblers.

Since the lock body has no pin channels bored from outside into the lock body for respective pin tumblers, no closure plugs, as explained above with respect to the prior art, are required for the padlock according to the invention. This ensures that the lock body can be colored and / or finished before the assembly of the padlock. A post-processing to secure, protect and / or obscure originally existing openings, plugs and / or transitions after assembly is not required, so that the coloring or finishing remains unimpaired. Furthermore, the material for the lock body can be selected regardless of whether it can be well finished or can be easily connected to a specific closure means, or whether it has a particularly good corrosion resistance. Rather, the material of the lock body, for example, from the viewpoints of high security, good processability, dyeability, finability and / or the price can be selected.

For receiving the tumbler housing, the lock body has a further receiving opening. The tumbler housing is substantially cylindrical and / or the further receiving opening is formed as a cylindrical receiving bore.

According to one embodiment, the tumbler housing is pressed in the lock body. The tumbler housing and the lock body can thus be non-positively connected to each other without separate connection means. For this purpose, the tumbler housing can be pressed into the lock body. For example can the lock body, as will be explained below, have a receiving opening for the tumbler housing into which the tumbler housing is inserted. In this case, the tumbler housing and the receiving opening may be formed to each other in the manner of an interference fit to produce a frictional connection between the tumbler housing and the lock body. It is also conceivable that at least parts of the surface of the tumbler housing by a force, such as a shock interact with surfaces of the lock body and are pressed or pressed in this way to the lock body. All types of compression (or combinations thereof) is common that they are structurally particularly simple and therefore can be done very inexpensively. In addition, the lock body is not attacked by such pressing, so that even a coloring and / or finishing of the lock body remains unaffected.

Alternatively or in addition to a crimping, the tumbler housing may, for example, also be accommodated in a form-locking manner in a fixed position in the lock body. For example, an axial fixing of the tumbler housing in the lock body by means of a snap ring engages in an associated groove in the lock body, while a positional fixation of the tumbler in the rotational direction by a complementary shape of the tumbler housing on the one hand and the cylinder core can be achieved on the other hand.

In another embodiment, a locking pin is provided to hold the cylinder core axially fixed in the lock body. In this case, the locking pin is used to immovably fix the cylinder core in the axial direction, so that the cylinder core can not slide or pulled out of the lock body. In this case, the cylinder core is merely axially fixed by means of the securing pin, while the rotation of the cylinder core about the cylinder axis is not blocked. However, in cooperation with the security pin the Rotation of the cylinder core to be limited to an angular range, as will be explained.

According to a development of the locking pin is inserted in a parallel to the at least one housing pin extending locking pin channel of the tumbler, in particular in a bore. In this case, the locking pin and the respective housing pins of the padlock can be aligned parallel to each other extending from the tumbler housing in the direction of the cylinder core. In particular, in the tumbler housing one or more of the safety pin channel similar or identical pin channels for a respective housing pin, in particular one or more holes provided. In this case, the pin channels for the locking pin and respective housing pins preferably have the same diameter so that they may be e.g. can be inexpensively manufactured with the same tool. Accordingly, the securing pin can be shaped substantially similar to a housing pin and in particular have the same diameter. In contrast to a longitudinally displaceable pin tumbler, the securing pin can be used immovably in the pin channel, at least with respect to its longitudinal extent.

Consequently, when the locking pin is inserted in the tumbler housing, the cylinder core is held axially in the lock body indirectly by axially fixing the cylinder core via the locking pin relative to the tumbler housing while the tumbler housing is fixedly received in the lock body.

Furthermore, it is advantageous if the locking pin is inserted in a continuous pin channel of the tumbler housing. Continuous pin channels can be produced in a particularly simple manner. Also, respective pin channels for a respective housing pin may be formed in the tumbler housing as a continuous pin channels. The locking pin and respective housing pins with respective pen springs can then be very easily inserted into the pin channels. Due to the fact that the tumbler housing is accommodated in the lock body, the end stop which is missing in the case of continuous pin channels can be formed in particular by the lock body itself.

In an advantageous embodiment of the locking pin is arranged in Schlüsseleinführrichtung behind the at least one housing pin. The axial fixation of the cylinder core in the lock body then takes place particularly deep in the cylinder core, that is, particularly far away from the key insertion opening of a keyway formed in the cylinder core. As a result, an improved security of the fixing of the cylinder core is achieved in the padlock, since the locking pin is not accessible from the outside.

Preferably, the cylinder core is held axially fixed only by the locking pin in the lock body. In this way, the cylinder core can be coupled via the locking pin with the tumbler housing and fixed on the tumbler housing axially in the lock body. Since the cylinder core is thus not coupled directly to the lock body, the cylinder core and the tumbler housing can be used together with respective pin tumblers arranged therebetween and the locking pin in the lock body. For example, by the above-described pressing the tumbler housing can then be firmly connected to the lock body, whereby the cylinder core is held axially fixed in the lock body. This simple and reliable assembly allows cost-effective high flexibility, e.g. when combining different, e.g. different colored, lock body coded for different key units of cylinder core and tumbler housing.

According to one embodiment, the securing pin engages in a groove of the cylinder core extending in the circumferential direction with respect to the cylinder axis. by virtue of this course of the groove, the cylinder core and the tumbler housing can be coupled by the engagement of the locking pin in the groove such that a rotational movement of the cylinder core is made possible around its cylinder axis, an axial movement of the cylinder core relative to the tumbler housing, however, is not possible.

In this case, the coupling of the cylinder core with the tumbler housing by means of engaging in said groove locking pin not only serve the axial fixation of the cylinder core with simultaneous rotational mobility, but also selectively restrict this rotational mobility through the length of the groove. In an advantageous embodiment, the rotation of the cylinder core is thereby limited to an angular range of less than 180 °, in particular less than 120 °, preferably about 110 °, that the groove extends only over a corresponding angular range of the circumference of the cylinder core. For actuating a locking device of the padlock by means of an inserted into the aforementioned keyway of the cylinder core key such an angular range may be sufficient. In principle, the angle range through the course and the shape of the groove or by other elements even much more, be limited to about 45 ° or less.

Preferably, the groove is arranged in Schlüsseleinführrichtung behind the at least one core pin. Thus, the key insertion in the front and predominant part of the cylinder core can accommodate an axial keyway and provide for each radial Kernstiftkanäle, while in a distal of the opening of the key channel area in which a key at most protrudes with its tip, space for said groove remains ,

According to an advantageous embodiment, both the receiving opening for receiving the cylinder core and the further receiving opening for receiving the tumbler housing are each formed as a cylindrical receiving bore. In this case, the respective receiving opening is preferably adapted to the shape of the cylinder core or the tumbler housing such that the cylinder core and / or the tumbler housing are substantially completely received in the lock body and in particular flush or approximately flush with an outer surface of the lock housing.

According to a further development, the two receiving bores are arranged next to one another and overlapping one another. In particular, the two receiving openings are cylindrical and aligned parallel to each other. Such receiving openings can be easily drilled in a solid lock body. If the receiving openings have the same diameter, advantageously the same tool can be used for this purpose. In this case, a boundary region between the cylinder core and the tumbler housing can be formed by the overlap of the two receiving openings, in which the cylinder core and the tumbler housing can cooperate with each other in particular via respective pin tumblers and / or the locking pin.

In another embodiment, the tumbler housing is substantially cylindrical in shape and aligned parallel to the cylinder core. In this case, the tumbler housing as well as the cylinder core can be integrally formed. The cylinder core and the tumbler housing preferably have the same diameter. In a cylindrical tumbler housing pin channels, in particular holes for vertical respective housing pins or for a locking pin, the cylinder axis of the tumbler housing perpendicular intersect and in particular be formed as a continuous pin channels.

According to an advantageous development, the tumbler housing has an axially extending, in cross-section circular arc-shaped recess on which rests the cylinder core. This allows a positive rotation the tumbler housing relative to the cylinder core can be effected. The recess can just correspond to the said overlap of the receiving openings for the cylinder core or for the tumbler housing. In the concave surface formed by the recess of the tumbler housing then pin channels for respective housing pins or a safety pin can open. In this way, respective pin tumblers or the locking pin on this concave surface, which forms an interface between the tumbler housing and the cylinder core, with associated pin channels, in particular holes, for respective core pins or with the groove in the cylinder core cooperate.

In a preferred embodiment, a locking device is provided for selectively locking and releasing the bracket, which includes a drive with the cylinder core coupled rotary latch and two blocking balls, which can be urged by means of the rotary latch in a respective locking recess of the stirrup legs of the bracket. This locking device then forms together with the driving cylinder core a structurally simple and reliable locking mechanism of the padlock.

The invention further relates to a method for producing a padlock, as described above, in which initially the lock body of the padlock is finished, in particular colored, and then the padlock is assembled. The assembly of the padlock includes in particular that the tumbler housing is pressed in the lock body.

In Fig. 1 an exemplary embodiment of a padlock 11 according to the invention is shown. The padlock 11 comprises a solid lock body 13, for example of iron or an iron alloy such as steel, which is refined on its outer surface (eg provided with a corrosion protection) and / or colored. In this case, the lock body 13 may be formed in particular by cutting to length a strand material. But it is also conceivable that the lock body 13 is made by casting. In two bracket shots (not visible in the figures) of the lock body 13 is a bracket 15 with a long bar leg 17 and a short bar leg 19 (see. Fig. 2 and 3 ) used. The bracket 15 is held linearly displaceable in the bracket receptacles, so that the short bar leg 19 emerge in an open position of the padlock 11 from the associated bow holder and so can open the padlock.

On the opposite side of the temple holders of the lock body 13, a receiving opening in the form of a receiving bore 21 for a cylinder core 23 inserted therein and a similar further receiving opening in the form of a further receiving bore 25 for a tumbler housing 27 inserted therein are formed. The receiving bores 21, 25 of circular cross-section are arranged side by side and overlapping each other. The cylinder core 23 and the tumbler housing 27 terminate substantially flush with the lock body 13, wherein in the cylinder core 23 a circumferential chamfer to the slightly protruding from the lock body 13 outer end surface of the cylinder core 23 passes. In this end face there is a key insertion opening 29, which has an opening to a profiled in the cylinder core 23 profiled keyway 31 (see. Fig. 3 ).

As in the Fig. 2 and 3 can be seen, the cylinder core 23 is integrally formed cylindrical and aligned according to a cylinder axis Z. Likewise, the tumbler housing 27 is formed in one piece cylindrical and has the same diameter as the cylinder core 23, to which it is aligned in parallel. In this case, the tumbler housing 27 has a recess extending in the axial direction in cross-section arcuate recess, which corresponds to the overlap of the circular in cross-section receiving holes 21, 25. At this overlap of the cylinder core 23 abuts on the tumbler housing 27.

The remaining lateral surface 33 of the cylinder core 23 abuts directly against the inner lateral surface of the receiving bore 21 in the lock body 13 and is guided in a sliding manner upon rotation of the cylinder core 23 by the lateral surface of the receiving bore 21. In this way, the cylinder core 23 is mounted rotatably about the cylinder axis Z directly in the lock body 13.

On the other hand, the tumbler housing 27 is accommodated in a fixed position in the further locating bore 25 of the lock body 13 and fixed in a force-locking manner by pressing in the locating bore 25 for this purpose. Perpendicular to the cylinder axis Z to a locking pin 35 extends from the tumbler housing 27 into a groove 37 of the cylinder core 23, which extends in a distal to the Schlüsseleinführöffnung 29 region of the cylinder core 23 in the circumferential direction. By engaging the locking pin 35 in the groove 37 of the cylinder core 23 is held relative to the tumbler housing 27 axially immovable. Since the tumbler housing 27 is pressed in a fixed position in the lock body 13, thus the cylinder core 23 is fixed relative to the lock body 13 in its axial position. Another fixing of the cylinder core 23 in the lock body 13 does not take place. The Groove 37 extends over an angular range of about 110 ° along the circumference of the cylinder core 23, so that the interaction of locking pin 35 and groove 37 also causes a rotational movement of the cylinder core 23 in the receiving bore 21 is limited to at most this angular range.

In the Fig. 2 and 3 Furthermore, a locking device 39 can be seen which comprises a drive bolt 41 operatively coupled to the cylinder core 23 and two blocking balls 43. Depending on its rotational position of the rotary latch 41 urges the blocking balls 43 radially outwardly into respective locking recesses 45 of the stirrup legs 17, 19 of the bracket 15 or allows the blocking balls 43 can escape from the locking recesses 45. In this way, the bracket 15 in its illustrated closed position by means of the locking device 39 optionally (as shown) will be locked or released.

The drive-effective coupling between the cylinder core 23 and the rotary latch 41 does not have to be torsionally rigid, but may have a defined clearance in order to allow a known automatic manner such that the bracket 15 in the position shown in the figures of the cylinder core 23 from the open position can be latched into the closed position. For this purpose, a return spring 47 is further provided, which is arranged between the cylinder core 23 and the rotary latch 41. Another spring 49 is disposed in the long bar leg 17 associated bracket receptacle and biases the bracket 15 in its open position, so that when the rotary latch 41 assumes a releasing position, the blocking balls 41 are urged out of Verrieglungsvertiefungen 45 and the bracket 15 in his open position is shifted.

Especially in Fig. 3 can be seen, the cylinder core 23 has a parallel to the cylinder axis Z extending row of six equidistant bores 51, 51 ' of the same diameter, which extend perpendicular to the cylinder axis Z radially from the outside to the keyway 31 through. In the of the Schlüsseleinführöffnung 29 furthest spaced bore 51 'protrudes partially into the locking pin 35, wherein the groove 37 opens into this bore 51'. In the remaining bores 51 respective core pins 53 of different lengths are used.

In the closed position of the cylinder core 23 shown in the figures, the bores 51, 51 'are aligned with corresponding through bores 55, 55' of the tumbler housing 27. The securing pin 35 is arranged in the bore 55 'furthest from the key insertion opening 29. In the remaining bores 55, respective housing pins 57 are inserted toward the cylinder core 23 and respective pin springs 59 are inserted toward the other side. If the tumbler housing 27 is inserted into the further receiving bore 25 of the lock body 13 as shown, the pin springs 59 are supported directly against the lock body 13 and thus clamp the housing pins 57 and the core pins 53 in the direction of the keyway 31.

The core pin 53, the housing pin 57 and the pin spring 59 of two aligned holes 51, 55 each form a pin tumbler. In the figures, just that position of the pin tumblers is shown, which is taken against the bias of the pin springs 59 usually only when a padlock assigned to the padlock (not shown) is inserted into the keyway 31. The associated key straightens the pin tumblers 53, 57, 59 so that the interface between the core pins 53 and the housing pins 57 coincides with the interface between the cylinder core 23 and the tumbler housing 27, so that the cylinder core 23 can be rotated. In all other positions of the pin tumblers 53, 57, 59 of the cylinder core 23 is locked by at least one Stiftzuhaltung 53, 57, 59 against rotation.

The illustrated embodiment of a padlock 11 according to the invention can be made particularly cost-effective due to the simplified structure in which instead of a complete lock cylinder only a cylinder core 23 is provided without a cylinder housing without the safety of the padlock 11 would be disproportionately impaired. In particular, due to the provided Zuhaltungsgehäuses 27, in the bores 55, the housing pins 57 are used, the lock body 13 unhurt and must not be post-processed or post-refurbished even after assembly of the padlock 11. This is not only advantageous in terms of safety, but also makes it possible to color the lock body 13 prior to assembly and / or to refine, without the coloring or finishing would be affected by the further production. In this way, it is possible to manufacture safe padlocks 11 with colored and / or finished appearance even in the entry-level price segment.
