Description

padlock

The invention relates to a padlock having a lock body and a lock ring, wherein the lock ring is removably retained at the lock body and has a first shank and a second shank. The padlock also has a rotatable latch and at least one blocking element, wherein the rotatable latch is rotatable about the axis of rotation at least between the release position and the latched position. The lock body includes a first receiving passage and a second receiving passage for receiving the first and second stem portions of the lock ring, respectively, and a receiving opening for removably receiving the lock cylinder, wherein the lock bladder has a coupling to or A rotatable closure tab that is operatively coupled to the rotatable latch can be driven. The rotatable latch member includes at least one drive portion adapted to urge the blocking element radially outward relative to the axis of rotation in a latching position of the rotatable latch in a blocking recess direction of the first stem.

This padlock is unlocked by a matching key actuating the lock. As a result, the lock cylinder of the lock cylinder is rotated, and the rotational movement of the lock cylinder is transmitted to the rotatable latch by closing the projection. The closing projection of the lock cylinder is a rotary drive element that is eccentric with respect to the axis of rotation. The closure tab can be fastened to the lock cylinder of the lock cylinder at a variable angular position. However, in the assembled state of the lock cylinder, the closing projection is rotationally fixedly coupled to the lock cylinder.

In the release position of the rotatable latch, the lock ring of the padlock can be opened to remove at least one of the stems of the lock ring from the associated receiving passage of the lock body. Conversely, in the latched position of the rotatable latch, both stems of the locking ring are secured in the associated receiving passages of the lock body.

For some applications, what is expected is that the lock of the padlock can be replaced by the user. For example, due to the interchangeability of the lock cylinder, the padlock can be integrated into an existing locking system in a simple manner. The lock can thus be mounted into a padlock having a locking mechanism associated with the locking system, whereby the key of the locking system can also be used for padlocks, and thus the use of the padlock is broader. For this purpose, the padlock can optionally be equipped with a plurality of different lock cylinders - for example from different manufacturers. For this purpose, it is also possible to provide a padlock that does not have its own lock, ie for modification by the user with his own lock.

The lock cylinder used in this type of padlock is usually a standardized lock. This means that the padlock must be sized for the associated receiving opening to enable the padlock to receive the lock. Alternatively, the conventional latching mechanism of the padlock can be combined with a replaceable lock cylinder. However, such padlocks are known to be too large and/or material intensive and labor intensive in manufacturing.

It is an object of the present invention to provide a padlock that is compact in size, inexpensive to manufacture, and highly secure against unauthorized unlocking.

This object is achieved by a padlock having the features of claim 1 and in particular the rotatable latch further comprising a blocking portion adapted to be rotatable in a tangential direction with respect to the axis of rotation The latching position of the latch engages into an associated blocking recess of the second stem.

Thus, in the latched position of the rotatable latch, the locking ring is fixed in the lock body by two different latching methods, ie on the one hand, radially outward in the direction of the blocking recess of the first stem Push (at least one) blocking element. On the other hand, the blocking portion of the rotatable latch member engages the blocking recess of the second stem portion of the lock ring in the tangential direction (ie, in the direction of rotation of the rotatable latch member). Thus, any necessary rotation of the rotatable latch is advantageously used for the additional latching of the lock ring, thereby enabling double latching (i.e., latching of the two lock ring stems). In addition, conventional blocking elements can be dispensed with for this purpose.

In addition, the rotatable latch in the lock body can be performed by using a blocking portion of the rotatable latch member (specifically, when the rotatable latch member is directly engaged into the blocking recess of the second lock ring portion by the blocking portion) An eccentric arrangement of the axis of rotation of the lock and/or an eccentric arrangement of the axis of rotation of the lock cylinder of the lock cylinder. The axis of rotation of the rotatable latch and/or the axis of rotation of the lock cylinder of the lock cylinder may be disposed adjacent the second stem of the lock ring, ie adjacent the axis of the respective receiving passage of the lock body, thereby making the lock better It is housed in the lock body, so that the size of the lock body can be reduced.

The lock body can thus be configured in particular to be smaller, since the lock cylinder only has to comply with a minimum distance from the axis of the receiving channel and thus a minimum distance from the shank of the lock ring. Thus, the unused space in the lock body is omitted as compared to the rotational axis of the rotatable latch and/or the lock cylinder centrally disposed between the receiving passages, whereby the padlock according to the invention can be made more compact Configuration.

Due to the compact design of the padlock according to the invention, the usual appearance of the padlock is generally more attractive to the end consumer, since the lock body (ie the lock housing) can be designed to be relatively slender and the key insertion opening can be placed in the lock body as usual. The underside.

According to the slender structural shape, efforts to reduce materials can achieve a low cost manufacturing of the lock body.

Since only the receiving passage for generating the locking ring stem and the insertion opening for generating the receiving opening and the undercut of the lock cylinder (ie the undercut in the bore) are required, the necessity of using a special tool is avoided, so The manufacturing process of the padlock can be achieved at low cost.

In addition, by using two different latching methods and the latching direction of the two locking ring shanks, the padlock is particularly well protected from unauthorized unlocking (eg, forcibly pulling the locking ring out of the lock body, Operate the latch mechanism). For example, the method for forced radial retraction of the blocking element does not have to be adapted to overcome the tangentially guided blocking of the rotatable latch.

The blocking portion of the rotatable latch can advantageously be directly engaged into the blocking recess of the second locking ring stem. Thus, there is no need to insert a mechanical unit that increases the size of the padlock between the rotatable latch and the barrier.

In order to actuate the blocking element, the drive section forms a cam track for transferring the blocking element, which is different from the circular path. Due to the cam track, the blocking element can be moved radially outwards as the rotatable latch rotates, so that the blocking element can engage into the blocking recess of the first stem. It is therefore possible to squeeze the blocking element into the blocking recess when attempting to remove the locking ring from the lock body in the latching position. At the same time, the blocking area of the rotatable latch The associated blocking recess is contacted such that the blocking element and the barrier at the two stems prevent removal of the locking ring. The stability of the latching mechanism is particularly enhanced due to the engagement of the blocking element and the barrier as compared to the use of a thinner latching plate.

The padlock according to the present invention is particularly suitable for removably receiving a commercial lock with a rotatable closure projection wherein the rotatable closure projection is operatively coupled to the rotatable latch drive of the padlock. Since the lock cylinder can only be accessed from one side when used in a padlock, a commercial semi-locking bladder can be specifically used as the lock cylinder. For example, in the case of no mechanical adaptation, a commercial profile lock which is standardized according to DIN 18252 and has a core receiving portion and a flange section, can be used.

To this end, the lock collar is inserted into the associated receiving opening of the lock body from the side of the lock body remote from the lock ring, ie from the underside of the use position of the padlock. Typically, the lock ring area is referred to as the upper side of the padlock and the area remote from the lock ring is referred to as the underside of the padlock.

In particular, the rotatable latch can be disposed within the receiving opening for the lock cylinder such that the rotatable latch forms an abutment for the lock when inserting the lock into the lock body, and thus the receiving opening on the upper side The boundary captures the rotatable latch in a radial direction between the bladder (and/or adapter, such as the adapter that will be described below). Since the lock can be removed or inserted on the underside of the lock body, a simple lock replacement can be made by this arrangement of the rotatable latch at the longitudinal end of the lock. The rotatable latch and the blocking element can remain in the lock body upon insertion and removal.

Advantageous embodiments of the invention will be described in the description, the appended claims, and the accompanying drawings.

According to an advantageous embodiment, the axis of rotation of the rotatable latch and/or the axis of rotation of the locking projection of the lock cylinder (or of the lock cylinder) received in the receiving opening are arranged relative to the first receiving channel of the lock body and The second receiving channel is offset from the center (for the two locking ring shanks), ie the respective axes of rotation are not arranged at the centre between the two receiving channels. Thus, the axis of rotation of the rotatable latch can be placed closer to the second stem of the lock ring, thereby reducing the radius of the rotatable latch. Since the rotatable latch is small, the padlock can be configured to be more space and material in turn. If the axis of rotation of the closing projection or the axis of rotation of the lock cylinder of the lock body is set closer to the second stem of the locking ring, the lock can be better accommodated in the lock body.

According to a further advantageous embodiment, the axis of rotation of the rotatable latch coincides with the axis of rotation of the closing projection (or lock cylinder) of the lock received in the receiving opening. In this way, the closure tab can be coupled to the rotatable latch by, for example, a direct form mounting connection without any complicated mechanical unit inserted into the lock cylinder. Therefore, both the rotatable latch and the lock cylinder (cylinder) are disposed off-center, and thus are particularly close to the second stem, thereby avoiding unnecessary space waste.

According to a preferred embodiment, the drive portion and the blocking portion are integrally configured at the rotatable latch. Thus, the drive portion and the blocking portion are specifically configurable in one piece with the rotatable latch member, whereby the rotational movement of the rotatable latch member is always transmitted to the blocking member and the blocking portion, and the rotatable latch member can be blocked The portion is directly joined to the associated blocking recess of the second lock ring stem. In this way, a secure and consistent latch of the padlock is ensured by means of a blocking element that moves in synchronism with the blocking portion.

Alternatively, however, the blocking portion can also generally be configured to be connected to a separate part of the rotatable latch member either rigidly or with a rotational gap. For example, the hardened metal can be used to make the barrier while the other material (such as plastic) can be used to form the rotatable latch to reduce weight.

According to a further advantageous embodiment, the blocking element is elongate. This length of the blocking element can be set in particular in the direction of the latching movement of the blocking element (i.e. in the radial direction relative to the axis of rotation of the rotary latch). The spacing between the drive portion of the rotatable latch and the blocking recess of the first stem caused by the eccentric arrangement of the axis of rotation of the rotatable latch is bridged by the elongated design of the blocking element.

The barrier element preferably has at least one rounded (preferably annular) end. Therefore, when attempting to forcibly remove the lock ring from the lock body, the annular end portion is squeezed into the blocking recess of the first lock ring stem portion, wherein due to the annular design, a good force distribution on the enlarged surface of the blocking member and the blocking recess portion is caused. . Thus, the rounded or annular end makes it more difficult to shear the ends of the blocking element. This greatly increases the force required to break the padlock.

The shape of the elongated blocking element may in particular be formed by two hemispheres connected by a cylindrical joint.

Alternatively, at least two blocking spheres may be provided as blocking elements and one blocking sphere may be disposed behind the other blocking sphere, wherein the force of the driving portion of the rotatable latch is transmitted from the first blocking sphere to the first Two blocks the sphere.

According to a preferred embodiment, the blocking element and the blocking portion of the rotatable latch are relative to each other with respect to the axis of rotation of the rotatable latch Offset setting. Thus, the blocking element and the blocking portion can be arranged at different layers (ie horizontal) when viewed along the axis of rotation. If, for example, the blocking portion of the rotatable latch (and thus the blocking recess of the second stem of the locking ring when fully inserted into the lock) is further down in the lock body, then when the lock ring is opened (in the rotatable latch) The release position of the lock member can only remove the blocking recess of the first rod portion from the lock body, while the blocking recess portion of the second rod portion remains in the lock body.

The rotatable latch member advantageously includes a first layer and a second layer, each of which is generally formed in a disk shape and disposed up and down along a rotational axis of the rotatable latch member. Thus, the rotatable latch can be formed in the form of a tower wherein the center of each disc is located on the axis of rotation of the rotatable latch. Each layer may extend specifically perpendicular to the axis of rotation of the rotatable latch.

The first layer preferably includes a drive portion and the second layer includes a barrier portion of the rotatable latch member. Due to the arrangement of the blocking portion and the driving portion on the different layers, the blocking portion and the driving portion can be offset relative to each other with respect to the axis of rotation. In addition, the mechanical loads on the rotatable latch can be distributed over different layers.

In addition to the barrier, the second layer may also include a release portion and preferably also an assembly portion. In the region of the release portion, the radius of the second layer of the rotatable latch member can be smaller than the radius in the region of the blocking portion, wherein the release portion of the rotatable latch member can be rotated by the rotatable latch member to the release position Bring into the area of the second pole. Therefore, the release portion is not engaged into the blocking recess of the second stem portion, and the lock ring can be partially removed from the lock body until, for example, the fixed portion area of the lock ring contacts the release portion, thereby preventing the lock from being completed Remove the lock ring completely.

If the rotatable latch is further rotated to the assembled position, the fitting portion of the rotatable latch can be brought into the region of the second lock ring portion, wherein the radius of the second layer in the radius of the fitting portion region is less than The radius of the second layer in the area of the release. Therefore, the fixing portion of the lock ring can be moved through the fitting portion, and the lock ring can be completely removed from the lock body. Similarly, when the padlock is manufactured, the lock ring can be inserted into the lock body when the rotatable latch is in the assembled position.

According to a preferred embodiment, the rotatable latch comprises a third layer between the first layer and the second layer, wherein the rotatable latch can be in the third layer in the radial and/or axial direction Supported at the lock. To this end, the first and third layers can be designed to be hollow and each can be provided with a peripheral slit. The flange portion of the lock can protrude from the peripheral slit, for example. At the same time, the rotatable latch member can also form an abutment for the lock cylinder in the axial direction.

The lock may not necessarily be a component of a padlock, i.e., where the provided padlock is to be retrofitted by a commercial lock (e.g., an existing lockout system). However, according to a preferred embodiment, the lock cylinder is an assembly of a padlock. In this embodiment, the lock cylinder may include a lock cylinder, the lock cylinder is rotatably supported in the lock case, and the closing protrusion is rotatably fixedly coupled to the lock cylinder.

The closure projection of the lock cylinder preferably projects into the slit of the rotatable latch member, wherein there is preferably a rotational gap between the closure projection and the rotatable latch member. The closing protrusion may specifically protrude into the above-mentioned peripheral slit of the second layer, and may be in contact with the slit when the rotational movement of the protruding portion is closed The side walls are in contact to transmit rotational motion of the closure projection to the rotatable latch. In other words, the two lateral boundaries of the peripheral slit function as abutting edges. Due to the rotational gap, it is easier to insert the closure projection of the lock cylinder into the peripheral cutout of the rotatable latch and or to bring the closure projection of the bladder into the flush angle with the lock when inserting the lock into the lock body Position so that the lock can be inserted into the lock body or the lock can be removed from the lock body.

Preferably, the adapter is disposed in the receiving opening of the lock body between the lock cylinder and the lock body, and the adapter is rotatable in the release position and/or the latch position of the rotatable latch member for the closing projection of the lock cylinder Adjacent part. Thus, the adapter can be prevented from rotating the rotatable latch to an undesired position. At the same time, the adapter can also at least partially adapt the contour of the receiving opening of the lock body to the contour of the lock collar, and the adapter can also hold the rotatable latch and the blocking element in the receiving opening of the lock body. For example, the adapter can be secured within the receiving opening of the lock body by a pin or screw or by a press fit. Alternatively, however, a releasable fixation can be provided in the lock body whereby the padlock can be adapted to a different lock cylinder by replacing the adapter.

According to a further advantageous embodiment, the receiving channel of the lock body (for the two locking ring shanks) extends parallel to the axis of rotation of the rotatable latch. Thereby, the lock cylinder can be inserted into the padlock from the underside of the padlock, so that the conventional design is effective for the user, wherein the key insertion opening is provided on the lower side of the housing.

According to a further advantageous embodiment, a channel opening for the locking screw is provided in the locking body, and the locking screw can be fastened in the receiving opening of the locking body by the locking screw. The lock cylinder is additionally fixed by the lock screw to prevent the lock cylinder from being pulled out of the lock body.

The lock cylinder is preferably a profile cylinder standardized according to DIN 18252 and includes a lock housing having a rotatably supported hollow cylindrical core receiving portion for the lock cylinder and a flange portion, the flange The portion protrudes radially away from the core receiving portion, and a marble may be provided in the flange portion. Thus the shape of the cross-section of the lock bladder is asymmetrical (i.e. not annular), wherein the lock-shell housing incorporates the elongate flange portion from the annular cross-section of the core receiving portion. When the lock housing is inserted into the padlock (ie, inserted into the associated receiving opening of the lock body), the core receiving portion of the lock housing can be closer to the second receiving passage of the lock body (for the second stem of the lock ring) An axis, wherein the flange portion of the lock housing extends from the core receiving portion in the axial direction of the first receiving passage (for the first stem portion).

Due to the embodiment of the rotatable latch according to the invention, it is possible in particular to be the plane of symmetry of the lock cylinder (in particular the plane of symmetry of the profile lock that extends through the axis of rotation of the core receiver and the lock cylinder of the flange) and The central plane of the lock body coincides or extends parallel to the central plane of the lock body, wherein the axis of the two receiving passages of the lock body for the lock ring portion spans the central plane of the lock body. To this end, the plane of symmetry of the aforementioned receiving opening, in particular the lock body, may coincide with the central plane of the lock body or parallel to the central plane of the lock body. Thus, the end consumer can be provided with a conventional appearance of a usual padlock, wherein the keyhole of the lock cylinder (i.e., the slot key insertion opening of the lock cylinder) extends along the central plane of the lock body or parallel to the central plane of the lock body.

Components of the same or the same type are denoted by the same reference numerals in the drawings. 1 is a perspective view of a padlock according to the present invention; FIG. 2 is an exploded view of the padlock of FIG. 1; FIG. 3a is a bottom perspective view of the rotatable latch; FIG. 3b is a plan view of the rotatable latch; 4 is a bottom perspective view of the lock body; FIG. 5 is a perspective view of the adapter; FIG. 6a is a first side perspective view of the padlock of FIG. 1 in an assembled state without the lock body; and FIG. 6b is a view A second side perspective view of the padlock of Figure 1 in an assembled state without a lock body.

The padlock 10 shown in Figure 1 includes a lock body 12 and a lock ring 14. A U-shaped lock ring is formed from a cylindrical material, and the lock ring includes a first stem portion 16 and a second stem portion 18. Both the first stem portion 16 and the second stem portion 18 are straight.

The padlock 10 can be moved from the latched state to the unlatched state and from the unlatched state to the latched state with the key 20. To this end, the key 20 can be inserted into the key insertion opening on the underside of the lock body 12, wherein the lower side of the lock body 12 is on the opposite side of the lock ring.

The padlock 10 of Fig. 1 is shown in an exploded view in Fig. 2. The first blocking recess 22 is provided in the first stem portion 16 of the lock ring 14, is disposed at the lower end portion of the first stem portion 16, and is partially cylindrical or partially annular in shape.

The lock ring 14 is formed entirely of a substantially annular cross section.

The second stem portion 18 is longer than the first stem portion 16 and is at the first A second blocking recess 24 is included in a region disposed below the end of the stem portion 16, wherein the second blocking recess 24 is formed by removing the parallelepiped-shaped region. The release recess 26 abuts the second blocking recess 24 from below, and the release recess 26 is formed by a concave recess facing the second stem portion 18 of the first stem portion 16.

The rotating portion 28 is adjacent the lower portion of the release recess 26 and has an annular cross-section that is reduced in size relative to the generally cross-section of the lock ring 14, i.e., the rotating portion 28 forms an annular groove.

The fixing portion 30 has a circular cross section corresponding to a general cross section of the lock ring 14, and the fixing portion 30 forms an end portion of the second rod portion 18.

In the latched state of the padlock 10, the first stem portion 16 extends into the first receiving channel 32 of the lock body 12 and the second stem portion 18 extends into the second receiving channel 34 of the lock body 12. The receiving passages 32, 34 can be considered to be open toward the upper side of the exterior of the lock body 12. The receiving channels 32, 34 are adapted to the cross section of the locking ring 14.

The lock body 12 is shown in more detail in Figure 4. The lock body 12 has a generally rectangular cross section with the longitudinal sides being arcuate outwardly. The receiving opening 36 is introduced into the lock body 12 from below. The receiving opening 36 is stepped down towards the top. A passage hole 38 for the lock screw is provided at the side surface.

A rotatable latch 40 (Fig. 2) is inserted into the receiving opening 36 and is in direct contact with the blocking element 42. The blocking element 42 is elongate and is formed by two hemispherical portions 44 and a cylindrical portion 46 that joins the hemispherical portion 44.

The rotatable latch 40 is formed of three layers like a tower (first 3a)). In the mounted state, the first layer 48 faces the U-shaped region of the lock ring 14 and is therefore at the top. The second layer 50 forms the lower end of the rotatable latch 40. The third layer 52 is disposed between the first layer 48 and the second layer 50.

In addition to the peripheral cuts and/or recesses, all of the layers 48, 50, 52 have a generally cylindrical outer surface with a radius of the layer increasing from top to bottom. This means that the radius of the first layer 48 is smaller than the radius of the third layer 52. The radius of the third layer 52 is less than the radius of the second layer 50 (Fig. 3b).

A cylindrical recess that cooperates with the peripheral adjacent region as the drive portion 54 is inserted into the first layer 48, i.e., inserted into the upper layer.

The third layer 52 (i.e., the intermediate layer) is hollow cylindrical, and its sleeve surface is cut in an angular region of about 70°. The slit 55 is defined by two adjacent surfaces 56a, 56b.

The second layer 50 (i.e., the lower layer) includes a slit 57 in which the sleeve surface is cut by about 20, having drive surfaces 58a, 58b, and the drive surfaces 58a, 58b defining the slit 57 are formed by the convergence of the flat portions. The region of the second plane having the largest radius defines a barrier 60 at which a release portion 62 having a smaller radius than the barrier portion 60 is circumferentially adjacently disposed. A partially cylindrical cutout is provided in the second plane 50, the slit being circumferentially adjacent to the release portion 62, and the fitting portion 64 is formed. The fitting portion 64 is continuous in the third (i.e., intermediate) layer 52.

A lock 66 in the form of a commercial semi-conical lock can be placed under the rotatable latch 40 (Fig. 2). The lock cylinder 66 has a rotatable lock cylinder 68 that is supported in the lock cylinder receiving portion 70 and rotatable about an axis of rotation. The flange portion 72 provided with the marble 74 extends perpendicular to the rotation axis. For locking A threaded hole 76 (not shown) of the screw is provided in the flange portion 72. The lock cylinder receiving portion 70 and the flange portion 72 together form the lock housing 77 of the lock cylinder 66 (Fig. 2).

A closing projection 78 that is rotationally fixedly coupled to the lock cylinder 68 is provided at the longitudinal end of the lock cylinder 68 (the upper end portion of the use position of the lock cylinder 66 after assembly). Thus the closure tab 78 can rotate with the lock cylinder 68 about its axis of rotation. The bladder 66 also includes an integral support and cover 80 at its rear end.

The bladder 66 is retained in the adapter 82 (Fig. 5) and the outer dimensions of the adapter 82 are adapted to receive the opening 36. The adapter 82 includes an inner recess 84 adapted to the bladder 66 and a bearing surface 86 at its end face (on the upper side of the use position of the assembled adapter 82), and the bearing surface is abruptly adjacent the adjacent surfaces 88a, 88b decline. The outer sleeve surface of the adapter member 82 is provided with a partial cylindrical passage slit 90 extending parallel to the direction of the axis of rotation of the lock cylinder 68. The adapter 82 has a peripheral interruption 92 for receiving the flange portion 72 of the lock cylinder 66.

Figure 6 shows the assembled padlock 10 in the latched position. The adapter 82 is permanently fixed in the lock body 12 by pins (not shown) extending in the lateral direction (Figs. 1 and 2). In the assembled state, the rotatable latch 40 is positioned on the bearing surface 86 of the adapter 82 through the lower end surface of the second layer (ie, the lower layer) 50. Additionally, the support and termination portion 80 of the bladder 66 extends through the slit 55 of the third layer (i.e., intermediate layer) 52 into the third layer 52 of the rotatable latch 40. To this end, the rotatable latch 40 is rotatably supported at the support and terminator 80 of the bladder 66, for which purpose the extension is arranged to surround An axis corresponding to the aforementioned rotation axis of the lock cylinder 68 or the closing projection 78.

The locking projection 78 projects from the slit 57 of the second layer 50 (Fig. 6a), and the rotational movement of the locking projection 78 is constrained by the adjacent surfaces 88a, 88b of the adapter 82.

The bladder 66 is retained in the adapter 82 with the flange portion 72 of the bladder 66 projecting radially from the adapter 82 relative to the axis of rotation of the rotatable latch 40 by the peripheral interruption 92. The adapter member 82 and the lock cylinder 66 form a flush end portion at their lower end portions that coincides with the lower side of the lock body 12.

The first stem portion 16 of the lock ring 14 is configured to be substantially aligned with the radial end of the flange portion 72 of the bladder 66 in the direction of the axis of rotation of the rotatable latch 40.

In order to replace the lock cylinder 66, the lock screw is first removed from the lock body 12. Subsequently, the lock cylinder 70 is rotated by the key 20 such that the locking projection 78 is oriented in alignment with the flange portion 72 of the bladder 66. In order to avoid rotation of the rotary latch 40, the slit 57 of the second layer 50 of the rotatable latch 40 is slightly larger than the closure projection 78 to form a small amount of the rotatable latch 40 relative to the closure projection 78. Rotate the gap. In the aligned position in which the tab 78 is closed, the lock 66 can be pulled out of the lock body 12 by the key 20.

When the bladder 66 (or a different bladder 66) is inserted into the receiving opening 36 of the lock body 12 (ie, the insert adapter 82), the closure projection 78 is again oriented to align with the flange portion 72 of the bladder 66. The lock 66 is inserted into the lock body 12 until the support and termination 80 of the lock 66 contacts the rotatable latch 40. Thus, the rotatable latch 40 is located in the axial extension of the lock cylinder 70. Subsequently, the lock cylinder 66 is fixed in the lock body 12 by a lock screw. The key can now be set to a zero position and can be removed from the lock cylinder 70, thereby providing the rotatable latch 40 in a latched position wherein the rotatable latch 40 is rotated relative to the flange portion 72 of the bladder 66 .

In the latched position of the rotatable latch 40, the locking projection 78 of the bladder 66 rotates toward the drive surface 58a, and the rotatable latch 40 rotates until the drive surface 58a (as viewed in the direction of the axis of rotation) The orientation is generally aligned with the abutment surface 88a of the adapter 82 (Fig. 6a). Thereby, the blocking portion 60 of the rotatable latch 40 is disposed in the second blocking recess 24 of the lock ring 14 (Fig. 6b). In addition, the blocking element 42 is pushed by the drive portion 54 of the rotatable latch 40 in the direction of the first blocking recess 22 of the locking ring 14, and the blocking element is passed through the corresponding portion of the sleeve surface of the first layer (ie the upper layer) 48. 42 is kept in place. The blocking element 42 engages in a radial direction into the first blocking recess 22 of the locking ring 14 with respect to the axis of rotation of the lock cylinder 68 and thus with respect to the axis of rotation of the rotatable latch 40, the rotatable latch 40 The blocking portion 60 engages in the tangential direction into the second blocking recess 24 of the lock ring 14.

If an attempt is made to remove the lock ring 14 from the lock body 12 in the latched position, the lower surface of the lock ring 14 defined by the second stop recess 24 abuts the barrier 60 of the rotatable latch 40. In addition, the radially outer hemispherical portion 44 of the blocking element 42 is forced into the first blocking recess 22 of the locking ring 14. In this way, the removal of the lock ring 14 at the latched position of the rotatable latch 40 is effectively prevented.

If the padlock 10 will be unlocked and the lock ring 14 is released, then The lock cylinder 68 is rotated from the zero position by the key 20, so that the closing projection 78 is similarly rotated (in the counterclockwise plan view in the illustrated embodiment) to the flange portion 72 by the flange portion 72 of the lock cylinder 66. The other side. To this end, the projection is closed before the drive effectively contacts the closure tab 78 with the drive surface 58b of the rotatable latch 40 and counterclockwise rotation of the rotatable latch 40 on the support surface 86 and the support and termination 80 The portion 78 first overcomes the aforementioned rotational gap of the rotatable latch 40. Thereby, the driving portion 54 of the rotary latch 40 is brought into the region of the radially inner hemispherical portion 44 of the blocking member 42, that is, the blocking member 42 can be radially retracted in the direction of the recess formed by the driving portion 54. In addition, the release portion 62 of the rotatable latch 40 is rotated into the angular region of the second blocking recess 24 of the locking ring 14, ie the blocking portion 60 of the rotatable latch 40 is rotated out of the second blocking recess 24. This double latching action requires the closure tab 78 to rotate only along the small angle region, despite the aforementioned rotational gap of the rotatable latch 40. In particular, it is not necessary to have the closed projections 78 of the bladder 66 aligned with respect to the flange portion 72 of the bladder 66 on either side of the flange portion 72 of the bladder 66 (90° position). Thus, the lock body 12 can be relatively flat, as shown in the bottom view according to Fig. 4.

In this position of the rotatable latch 40, referred to as the release position, the lock ring 14 can be partially moved upwardly out of the lock body 12, thereby pushing the blocking member 42 into the drive portion 54. Upon removal, the release recess 26 of the second lock ring lever 18 and the release portion 62 of the rotatable latch 40 move past each other until the fixed portion 30 of the second lock ring portion 18 abuts the release portion 62 from below. In this position, the rotating portion 28 of the second locking ring portion 18 is located on the layer of the release portion 62 of the rotatable latch 40 such that the locking ring 14 can be wound around the second portion 18 rotations.

In the released position, the closure tab 78 of the bladder 66 contacts the abutment surface 88b of the adapter 82. In order to be able to move the rotatable latch 40 further counterclockwise, the bladder 66 must be removed. With the bladder 66 removed, the rotatable latch 40 can be rotated beyond the release position and into the so-called assembled position. To this end, the rotatable latch 40 has an engagement slot 94 (Fig. 3a), for example, for a screwdriver, and the rotatable latch 40 can be rotated to the assembled position by the engagement slot 94 with the lock 66 removed. . In the assembled position, the rotatable latch 40 is aligned such that the mounting portion 64 is rotated to the angular position of the second lock ring portion 18, thereby arranging the mounting portion 64 in the axial direction with the adapter 82 The channel slits 90 are aligned. Therefore, the fixing portion 30 is no longer blocked by the release portion 62 of the rotatable latch 40, and the lock ring 14 can be completely removed from the lock body 12.

Starting again from the release position, the lock ring 14 is fully inserted into the lock body 12 to lock the padlock 10, and the lock cylinder 68 is rotated clockwise (as viewed from above) with the key 20, which rotates the rotatable latch 40 to the position shown (Figure 6) The latch position. To this end, the blocking element 42 is pushed into the first blocking recess 22 of the locking ring 14 by the drive portion 54 of the rotatable latch 40, and the rotatable latch 40 is coupled to the second of the locking ring 14 in its rotational direction. The recess 24 is blocked. It is then impossible to open the lock ring 14 without authorization.
