Abstract

A padlock having a lock body and a hoop that is displaceably supported at the lock body between a closed position in which its first hoop end and its opposite second hoop end engage into the lock body and an open position in which at least its second hoop end is released from the lock body comprises a cylinder arrangement that is formed separately from the lock body and a cylinder core rotatable about a cylinder axis by means of an associated key, with the cylinder core directly contacting the lock body. In this respect, the cylinder arrangement is inserted into a receiver of the lock body and cooperates with a latch mechanism of the padlock such that the latch mechanism blocks the hoop against a displacement from the closed position in a latched position of the cylinder core and releases it for a displacement into the open position in an unlatched position of the cylinder core. The cylinder arrangement furthermore comprises at least one tumbler that is movably received in the cylinder arrangement, blocks the cylinder core against a rotation out of the latched position, or releases it for a rotation into the unlatched position in dependence on its respective position and is completely arranged within the cylinder arrangement as well as a resiliently supported holding pin that engages behind an abutment edge of the lock body to hold the cylinder arrangement in the receiver of the lock body with shape matching.

Description

   Padlock   

The invention relates to a padlock, which has a lock body and a hoop which is supported at the lock body between the closed position and the open position. Engages into the lock body, and at least the second hoop end of the hoop is released from the lock body in the open position.

The padlock includes a cylindrical configuration, which is formed separately from the lock body and around a cylindrical core that is rotatable against a cylindrical shaft by a corresponding key. In this purpose, the cylindrical configuration is inserted into the receiving cylinder of the lock body and cooperates with the latch mechanism of the padlock, so that the latch mechanism prevents the hoop from being displaced from the closed position in the latch position of the cylindrical core, and Release the hoop displacement into the open position at the unlocked position of the cylindrical core. The cylindrical configuration further includes at least one brake bolt, the at least one brake bolt is movably received in the cylindrical configuration, and according to the individual position of the at least one brake bolt, the cylindrical core is prevented from rotating away from the latch position or the cylindrical core is released Rotate into this unlocked position.

Padlocks of this type are known, for example, from DE 10 2009 023 561 A1 and DE 10 2011 009 591 A1.

Since the padlock in particular provides fixing of objects, it is important that the padlock is closed reliably. However, how much obstruction is perceived by authorized persons who want to open the padlock violently also contributes to padlock security. It is therefore helpful if the padlock appears as sturdy and as stable as possible. Especially with a low-priced padlock, it is even more important that the authorized person cannot establish the impression that the padlock can easily be opened.

In comparison, the material that can contribute to the padlock in a beneficial manner that is perceived to be solid and weighty is die casting, especially zinc die casting, which can be used in particular on the lock body of the padlock. A particular advantage of the casting process is also in this purpose, such as the large number of "drillings" of the hoop receiving barrel for the end of the hoop and the receiving barrel for the barrel configuration does not require drilling, but even This casting shape can be determined in advance. This method not only simplifies the production, but also reduces the waste caused in the production. However, there may be disadvantages to drilling, especially smaller ones, which must be additionally provided and cannot be produced during casting. Zinc casting is more difficult to drill than higher quality materials such as brass .

A further disadvantage of this material or an equivalent material may also result from this smaller corrosion resistance. Parts of the padlock formed from such materials, especially the lock body, must generally be provided with corrosion protection. This protection also applies to, for example, a lock body made of iron. However, components made of such materials can be fully corrosion resistant by corresponding treatments, for example, through the use of coatings for corrosion protection, brushing and varnishing, and can also display similar to higher quality materials, For example, brushed stainless steel.

However, in a padlock in which the lock body itself includes such materials, however, difficulty may arise in the component having the lock body in which the component is received in the lock body.

For example, it is conventional for a padlock having a lock body composed of brass to provide a receiving barrel for a ball of the padlock and when drilling directly into the lock body, the lock body is drilled into The inside of the lock body and the lock body are subsequently blocked by the brass stop pin to the outside such that the borehole is imperceptible or imperceptible. It is not possible for the lock body to provide such a step with a corrosion-protective coating because the coating will be damaged by the drilling and the lock body will therefore be corroded in the area of the drilling and the stop pin. Repeated coatings are costly and time consuming and are generally unnecessary from this point of view in the manufacturing process. Furthermore, the stop pin composed of the individual material cannot be provided in a correspondingly universal manner like a brass stop pin. In addition, such steps are relatively expensive and time consuming from a technical production standpoint. Another disadvantage is more likely to come from the fact that the stop pin may be released again from the borehole under certain circumstances, such as when the padlock is dropped and thus subjected to a heavy impact.

In addition to providing the cylinder bore drilled in the lock body to receive the cylindrical configuration of the padlock at least partially directly in the lock body, in addition to the cylindrical core, the cylindrical configuration may include a cylindrical housing, where The cylindrical core is received so that the cylindrical core is surrounded by the cylindrical casing in a peripheral direction with respect to the cylindrical axis. For this purpose, the cylindrical housing has a sufficiently radial extension at least in partial angles so that a receiving cylinder for a brake bolt can be provided in this area. When such a cylindrical configuration is inserted into the inside of the lock body, the cylindrical core is not directly supported in the lock body, but is fitted to the cylindrical housing via the cylindrical housing and via the brake bolt so that the key is correctly in accordance with the key. Pushing into the key receiving cylinder of the cylindrical core, the cylindrical core is blocked to prevent rotation against the cylindrical axis or released for rotation in a manner known per se.

However, it may be advantageous not to provide such a cylindrical housing around the cylindrical core for reasons of space or cost. However, the problem then arises where the receiving cylinder for the brake bolt can be provided. As mentioned above, depending on the particular material used, the standard solution to this problem, that is, the so-called provision of a receiving cylinder for the brake bolt as a bore directly into the lock body, may be inappropriate. In addition, for reasons of increased effort and / or cost, it has preferably been avoided to use the described drilling and blocking process of a cylindrical configuration without a cylindrical housing.

It must be further considered that the padlock needs to be configured so that the final assembly of the lock can be in the stage of downstream deployment of the individual component. It is particularly advantageous if the cylindrical configuration and the remaining padlock can be made at least substantially in advance, for example also in different production sites. It is particularly advantageous here if the cylindrical core does not need to be produced in a specific way for the padlock, but rather some standard cylindrical core known per se. This individual final assembly should then generally be able to be performed first at the dealer or agent. To this end, in particular the insertion and the fixing of the cylinder arranged in the lock body must be able to be handled in the simplest manner possible and preferably also reversible, for example for possible corrections or for replacement. In addition, the fixation should be reliable so that the security of the lock is not compromised.

The object of the present invention is to provide a padlock that can be produced inexpensively with simplicity, but with regard to individual materials and a reliable final assembly of the structural complexity.

A padlock having the features of the scope of application for patent item 1 is consistent with the purpose of the present invention and in particular that the cylindrical core directly contacts the lock body; wherein the brake bolt, especially each brake bolt, is completely disposed in the cylindrical configuration; and wherein The cylindrical configuration further has a retaining pin that is elastically supported behind the abutting edge of the lock body, and the cylindrical configuration is retained in the receiving cylinder of the lock body in a shape matching manner.

With this type of padlock, because the cylindrical core is in direct contact at the lock body, a cylindrical housing that engages around the cylindrical core cannot be provided. In contrast, the support of the cylindrical core in the lock body is produced directly at the lock body, especially at the inner surface of the receiving cylinder provided for receiving the cylindrical core. The receiving borehole does not necessarily need to be drilled in this respect, but can also be formed by casting in particular. This configuration of the cylindrical housing facilitates cheap production of the padlock.

Because a cylindrical shell is not provided, there is no brake pin in the cylindrical configuration provided in the cylindrical shell. In the padlock according to the present invention, the brake pin is not yet contained in the lock body itself. Instead, the brake bolster is completely disposed within the cylindrical configuration. The interactions communicated by the brake bolt and the blocking or release of the cylindrical core against its own cylindrical shaft are therefore not generated between the cylindrical core and the lock body, but instead can be used in different ways for this purpose. The cylindrical configuration is formed inside-however, without a cylindrical shell of known type.

The reliable fixing of the cylinder arranged in the lock body is therefore important for the overall safety of the padlock. To this end, the cylinder is provided with a retaining pin with elastic support. Since the retaining pin engages the abutting edge of the lock body, the cylindrical configuration is retained in a shape-matching manner, especially in the axial direction of the cylinder axis in the receiving cylinder of the lock body. This makes the displacement of the cylindrical configuration favorable to avoid reliably. This type of shape matching has a substantially increased security in this respect compared to pure force matching, for example by press-fitting.

This elasticity can be provided here to cancel the shape matching at least temporarily. For example, the elasticity may be necessary when the elastic configuration is inserted into the receiving cylinder of the lock body. The retaining pin is preferably displaced into the position here to engage the abutting edge of the lock body, and at the latest when it reaches the fully inserted position in which the cylinder is disposed in the lock body, it is retained in the interior As a result of this elastic support. The insertion of the cylindrical configuration in the final assembly of the padlock can be a way of latching which helps to be particularly simple, but nevertheless a reliable assembly.

In addition, the elastic support of the retaining pin enables it to resist the elastic force from the position of itself engaging behind the abutting edge of the lock body, so that the cylindrical configuration can be released again by the lock body, for example for replacement. However, only when the hoop of the padlock is in the open position, the best push back is preferably necessary. Conversely, in the closed position of the hoop, the retaining pin is preferably inaccessible so that release from the cylindrical configuration of the lock body is not possible.

According to the advantages of the embodiment, the outer surface of the cylindrical core directly contacts the lock body. When the cylindrical core rotates against the cylindrical shaft, the outer surface of the cylindrical core therefore slides directly at the inner surface of the receiving cylinder of the lock body for the cylindrical configuration. From a structural point of view, a particularly simple support and guidance of the cylindrical core in the lock body is presented in this way.

According to a further advantage of the embodiment, there is no separate cymbal receiving cylinder formed in the lock body for receiving the brake bolt of the cylindrical configuration. In particular, no receiving bore is provided in the lock body, which will be provided to receive the brake bolt therein at least partially directly. This simplifies the production of the lock body, especially when the lock body is produced by die casting.

According to a further advantage of the embodiment, the cylindrical configuration includes a brake bolt housing with the brake bolts, and in particular each brake bolt is partially received in the cylindrical core and partially in the brake bolt housing. The brake bolt housing occupies to some extent the work added to the cylindrical housing in known padlocks, but does not receive the cylindrical core like a cylindrical housing or engage in any way in the process. The cylindrical core. The blocking or release of the cylindrical core against rotation against its own cylindrical axis then depends in particular on which position the individual brake bolster is received in the cylindrical core and in which position of the brake bolster is adopted, respectively. .

In this regard, the brake pins may be formed in a manner known per se as pin bolts, each of which includes a core pin and a housing pin. As long as one of the brake pins is configured, the brake pin core is resistant to rotation, so that the core pin or the shell pin meshes through the boundary surface between the cylindrical core and the brake housing. The rotation of the cylindrical core is possible for all brake pins with the boundary surface between the cylindrical core and the brake pin housing only when the boundary surface between the core pin and the housing pin coincides. of. In this aspect, the brake bolt is advantageous to become an individual blocking position via a preload, from which the brake bolt is ideally all only moved to its own individual release position through a key combined with the padlock.

According to the advantage of further development, the brake bolt housing is radially disposed directly adjacent to the cylindrical core relative to the cylindrical shaft. The cylindrical core and the brake bolt housing therefore directly contact each other in the region of the periphery of the portion of the cylindrical core. In this way, the cylindrical configuration can be delicately formed. The cylindrical configuration can be at least substantially composed of the cylindrical core, the brake bolt housing, the brake bolt received in the two components, and the retaining pin. form. The final assembly of the padlock may therefore include a corresponding brake pin via a code selected for the padlock and a corresponding retaining pin inserted between the cylindrical core and the bolt housing. The cylindrical configuration formed in this way can therefore be inserted into the interior of the lock body, especially in a latching manner as described above to end the assembly. Since these steps are relatively simple and can be advantageously produced without the need for tools, the final assembly does not need to be performed by a technician, but can also be carried out further offline, for example in the sales end.

According to another or additional further development, a coupling element is formed between the brake bolt housing and the cylindrical core, and the coupling element is fixed, and in particular has a shape matching. The cylindrical core and the cylindrical housing are opposed to each other. They are arranged axially relative to each other with respect to the axis of the cylinder. Due to the axial coupling of the cylindrical core and the brake bolt housing realized in this way, the cylindrical core can also be fixed in the lock body via the brake bolt housing, in particular. For the brake bolt housing, the shape is matched and held in the receiving cylinder of the lock body by the retaining pin, and the cylindrical core may be fixed, especially by the coupling element in turn having a shape matching axially opposite In the brake bolt housing, the coupling element may be formed in a pin shape similar to the retaining pin.

The coupling element may, for example, be provided at the stopper housing and can be engaged inside the cutout at the cylindrical core. Despite the engagement of the coupling element, the cutout is then formed in this respect so that the rotation of the cylindrical core is at least not completely blocked. For example, the cut may be formed as an annular groove extending around the cylindrical axis. However, such an annular groove preferably does not extend beyond the entire perimeter, but is limited by a valid angular range, such as close to 90 °, or at least close to 90 °. Limitation of the rotation of the cylindrical core sufficiently for the angular range of the opening of the padlock can be achieved in a simple manner by such a design. The movability of the cylindrical core can in particular limit the rotation between its own latched position and its own unlocked position.

According to a further alternative or further development, the retaining pin is supported in the brake bolt housing. In this respect, the retaining pin can in particular protrude via the brake bolt housing and can be pushed back into the brake bolt housing as far as possible against the preload. In the extreme pushback state, the retaining pin can then be terminated in particular in alignment with the surface of the bolt housing so that the brake housing can be inserted into the receiving cylinder of the lock body or can be borrowed from It is removed by the receiving cylinder which is not obstructed by the holding pin.

According to the present invention, it is more preferable if the retaining pin and the coupling element are elastically supported by the same spring device, especially by a coil spring. The retaining pin and the coupling element can in particular be supported against the same spring device in opposite directions along the same axis. For example, the retaining pin may therefore be preloaded radially outwardly relative to the cylindrical housing to engage behind the abutting edge at the lock body and the coupling element may be preloaded radially inwardly relative to the brake pin The cylindrical core is fixed axially by the casing. In this aspect, the retaining pin, the coupling element and the spring device may be received at least partially in a continuous bore of the brake bolt housing, and it is preferable that the retaining pin and the coupling element are pre-prepared by the spring device. The load enters the individual ridge positions and partially protrudes from the borehole.

According to an advantageous embodiment, the retaining pin is at least substantially movable transversely to the cylindrical surface and is preloaded in the direction away from the cylindrical axis. The movability of the retaining pin is therefore aligned at least substantially at right angles to the cylindrical axis, and the directionality without movement necessarily intersects the cylindrical axis. As a preferred special example of this embodiment, the retaining pin is radially movable with respect to the cylindrical axis.

In a comparable manner, the at least one brake pin of the cylindrical configuration may be at least substantially laterally movable with respect to the cylindrical axis and may in particular be preloaded by individual spring means in a direction towards the cylindrical axis. , Such as a coil spring or the brake pin. This approach can be used in particular for all examples of the brake bolster in the cylindrical configuration. In this regard, an individual drilled hole in which the brake bolt is at least partially accommodated is advantageously provided in the brake bolt housing for each brake bolt. For example, the brake pin may include a core pin, a housing pin, and a spring device in each example, and it is preferable that the spring device is always completely received in the individual bore in the brake pin housing, Depending on the position, having the housing pin bolt is completely or partially received in the borehole and having the core pin bolt is partially or not entirely received in the borehole depending on the position.

For the drilling and selection of the brake bolt housing of the brake bolt, further drilling for the retaining pin can be arranged in parallel with each other and / or at regular intervals.

According to an advantageous embodiment, the continuation of the second hoop end of the hoop receiving cylinder or the hoop receiving cylinder by the retaining pin engaged behind the abutting edge is formed in the hoop receiving cylinder with the continuation In particular, the retaining pin, which is engaged behind the abutting edge, is configured to be accessible through the hoop receiving cylinder for the pushing back of the retaining pin and the continuation of the retaining pin, preferably along a straight path. If it is not provided that the hoop can be completely released by the lock body, the hoop receiving cylinder through which the retaining pin can be accessed, especially the hoop receiving cylinder is exposed to the open position of the hoop. In this method, since the hoop receiving cylinder is closed by engaging the hoop in the abutting edge, the retaining pin is obviously not accessible in the closed position of the hoop. The cylindrical configuration can therefore not be released by the lock body in the closed position. However, in the open position of the hoop, the retaining pin can be pushed back as far as possible through the hoop receiving cylinder so that the retaining pin no longer engages behind the abutting edge and the cylindrical configuration can therefore be released by the lock body.

Further use for the lock body preferably includes die casting, especially zinc die casting. As explained initially, this die-casting is particularly advantageous for related costs. In this respect, die-casting, especially zinc die-casting, can have advantages over other cheap materials in terms of simplification of production and a heavy and solid impression.

The present invention will be described in more detail in the following only by referring to the examples of the drawings.

Fig. 1 shows an embodiment of a padlock according to the invention in a schematic perspective view; Fig. 2 shows the cylindrical configuration of the same embodiment; Fig. 3 shows the same embodiment with the brake bolster housing shown separately The cylindrical configuration; Figures 4A and 4B show the same embodiment of the lock body with a separate display shown in a cross-sectional representation (Figure 4B); and Figures 5A and 5B show a brake bolt and retaining pin to isolate The same embodiment shown in the state (Figure 5A) and the lock body with the remaining components individually shown in the figure received in a sectional view (Figure 5B).

The padlock 11 shown in FIG. 1 includes a lock body 13 and a hoop 15, the first hoop end 17 of the hoop 13 and the second hoop end 19 of the hoop 13 are respectively engaged in the closed position shown in the closed position. The lock body 13 is in the first hoop receiving cylinder 21 and the second hoop receiving cylinder 23. The lock body 13 is produced by zinc die casting. The key 25 related to the padlock 11 is further shown, and the hoop 15 can be released using the key to move into the open position, where only the first hoop end 17 of the hoop 15 engages the first hoop Inside the receiving cylinder 21.

As is particularly recognized in FIG. 4A, the key 25 is inserted into a key groove of the cylindrical core 27. The cylindrical core 27 is formed in a substantially cylindrical shape with respect to the cylindrical axis Z, and is a part of the cylindrical configuration 29 shown in FIG. 2. In addition to the cylindrical core 27, it also includes a brake bolt housing 31 and 5 The stopper 33, the retaining pin 35, a pin-shaped coupling element 37, and a spring device 39 configured as a coil spring. The arrangement of these elements and themselves can be identified in FIG. 3 in particular, wherein the brake bolt housing 31 is shown in a radial displacement away from the cylindrical axis Z, but otherwise corresponds to FIG. 2.

Each of the brake pin 33 shown in FIG. 5A that is isolated from the retaining pin 35, the coupling element 37, and the spring device 39 includes a core pin 41, a housing pin 43, and a coil spring The spring device 45. Each brake bolt 33 is at least partially received in an individual brake bolt receiving cylinder 47, which is formed by two drilled holes, one of which is formed in the brake bolt housing 31, and another bore is formed in the cylindrical core 27, and the two bores are radially aligned toward the cylindrical axis Z.

The lock body 13 has a receiving cylinder 49 for receiving the cylindrical arrangement 29 (see Figs. 4B and 5B). When the cylindrical configuration 29 is received in the lock body 13, the stopper receiving cylinder 47 terminates in alignment with the inside of the receiving cylinder 49. The spring device 45 can be supported at the lock body, and the core pin and the housing pin 41, 43 can be preloaded in the direction radially toward the cylindrical axis Z.

The cylindrical arrangement 29 is encoded by the relative combination of core pins 41 of different lengths for a particular key 25. If the key 25 introduced into the cylindrical core 27 has appropriately coded teeth, the core pin and the housing pin 41, 43 are displaced against the load of the spring device 45, so that the core pin 41 and the The boundary surface between the housing pins 43 corresponds to the boundary surface between the cylindrical core 27 and the brake pin housing 31 for all the brake pins 33. Only in this state, the cylindrical core 27 can then rotate against the cylindrical axis Z relative to the brake bolt housing 31 itself, and can therefore be displaced to the unlocked position via the position of the display latch for release The hoop 15.

The bolt housing 31 further has a bolt receiving cylinder 51 aligned in parallel with the bolt receiving cylinder 47 and is therefore also aligned radially toward the cylindrical axis Z. The bolt receiving cylinder 51 and the brake bolt receiving cylinder 47 are arranged at regular intervals. The bolt receiving cylinder 51 is the farthest from the end of the padlock 11. The key can be introduced at the padlock 11 and It is therefore closest to the second hoop receiving cylinder 23.

The retaining pin 35, the coupling element 37, and the spring device 39 between the retaining pin 35 and the coupling element 37 are inserted into the pin receiving cylinder 51, so that the spring device 39 has a Z diameter relative to the cylindrical axis The retaining pin 35 is preloaded outward and the coupling element 37 is preloaded radially inward. In this aspect, the coupling element 37 projects radially inward from the brake bolt housing 31 and can be engaged in this way into a cutout 53 at the cylindrical core 27. The cutout 53 is formed by a portion of an annular groove that extends beyond the angular range effectively approaching 90 ° in the peripheral direction along the outer surface 55 of the cylindrical core 27 facing the cylindrical axis Z. This means that the movability of the rotation of the cylindrical core 27 is limited to the corresponding angular range to maintain the length of the degree as a result of the meshing of the coupling element 37. The axial displacement of the cylindrical core 27 in a direction away from the receiving cylinder 49 with respect to the brake bolt housing 31 by the coupling element 37 in the axial direction relative to the cylindrical axis Z is Additional blocking. In this manner, the cylindrical core 27 is axially held in the receiving cylinder of the lock body 13 via the brake bolt housing 31.

For this purpose, the brake bolt housing 31 must in turn be fixed relative to the lock body 13. For this purpose, the retaining pin 35 elastically supported by the spring device 39 projects radially outward from the pin receiving cylinder 51 and can be engaged in this manner with the receiving cylinder 49 formed in the lock body 13. Behind the edge 57 in the area. As recognized in the cross-sectional representation of Figures 4B and 5B, the abutting edge is located at the end of the continuation 59 of the second hoop receiving cylinder 23 extending in the extension of the second hoop receiving cylinder 23 But has a reduced diameter relative to the continuation 59. In this way, the retaining pin 35 engaged behind the abutting edge 57 can be accessed through the second hoop receiving cylinder 23 and can be pushed out of the shape-matching engagement behind the abutting edge 57 to release the The cylinder arrangement 29 in the lock body is fixed. However, this is only possible if the hoop 15 is not in its closed position.

As can be seen in Fig. 4A, the cylindrical core 27 is combined with a latch mechanism 63 including two relatively pre-loaded latch pins via a front end surface entrainment structure 61 (see also Figs. 2 and 3). The latch 65 is pre-loaded into the indicated position conforming to the latched position of the cylindrical core 27, and wherein the latch 65 engages a separate blocking section 67 of the hoop 15 with the hoop 15 fully inserted. In this regard, the latch 65 is chamfered such that when the hoop 15 is introduced into the lock body 13, the latch 65 is pushed back as much as possible against its own preload until the latch 65 is latched into the Within the blocking section 67. The hoop 15 is substantially blocked in a shape-matching manner in the opposite direction by the movement of the latch 65. The release of the hoop 15 can then only be caused by the cylindrical core 27 being rotated out of the displayed latch position into the unlocked position against the cylindrical axis Z, wherein the entrainment structure 61 displaces the latch 65 to resist coming from the block The preload of the segment 67 itself. As long as the hoop 15 is released, the latch is automatically displaced into its own open position by a further spring device 69, which is inserted into the first hoop receiving cylinder 21, and the spring device 69 Acts on the front end surface of the first hoop end 17 of the hoop 15.

The cylindrical core 27 is directly supported by the lock body 13 in rotation, and the outer surface 55 having the cylindrical core 27 directly contacts or slides along the inside of the receiving cylinder 49. The cylindrical housing for receiving and guiding the cylindrical core 27 can therefore be omitted, so that the padlock 11 can be simplified in structure and a relatively delicate design can be achieved.
