Abstract

The lock, particularly a shackle lock, has lock housings (15,21), where a free space (45) is provided in an axial extension of a lock cylinder (27). The lock cylinder or a part of the lock cylinder is shifted from an operating position into the free space by a pre-determined force impingement in the axial direction of the lock cylinder. The lock cylinder or a part of the lock cylinder takes sabotage position, in which the coupling of a latch (19) sets a cylinder core (33) out of function.

Description

The present invention relates to a lock, in particular a U-lock, with a lock housing, in which a lock cylinder of the lock is arranged, comprising a cylinder housing, a rotatably mounted in the cylinder housing cylinder core and an in drivingly effective relationship with the cylinder core entrainment means, and at least a bolt which is coupled via the entrainment device with the cylinder core. As a result, due to a rotation of the cylinder core in the opening direction of the bolt from a locking position into a release position movable, in particular by forced operation or by the latch is released only for movement from the locking position to the release position.

In a violent attempt to break such a lock, for example, a screwdriver is driven into the keyway of the cylinder core to achieve wedging of the screwdriver with the cylinder core. An attempt is then made to forcibly turn the cylinder core to shear the pin tumblers of the lock cylinder. This is intended to be achieved to rotate the driver in the opening direction to ultimately achieve a movement of the bolt from the locking position to the release position.

The invention has for its object to provide a lock of the type mentioned, which has an increased security against breakage.

This object is achieved by a lock with the features of claim 1 and in particular in that the lock housing in the axial extension of the lock cylinder has a receiving space, the lock cylinder or a part thereof by a predetermined application of force in the axial direction of the lock cylinder from an operating position in the Free space is displaceable to take a sabotage in which the coupling of the bolt with the cylinder core is disabled.

The receiving clearance makes it possible to use the force which is exerted on the cylinder core in the axial direction during a forceful introduction of a breaking tool, in order to consciously allow an axial movement of the lock cylinder or the part thereof. Here, the lock cylinder or the part thereof is transferred from the operating position in the sabotage, in which the chain of action is interrupted by the rotation of the cylinder core to the movement of the bolt in the release position, i. The bolt can not be moved in sabotage.

In the normal case moves in such a attempt to break the entire lock cylinder in the axial direction. If only a part of the lock cylinder is moved axially, this may in particular be the cylinder core of the lock cylinder and the driver device.

The driver device may generally be an integral part of the cylinder core or separately formed therefrom. In the latter case, said drive-effective relationship between the cylinder core and the driver device may be formed by a non-rotatable relationship in both directions of rotation, for example by positive locking Engagement between the cylinder core and the driving device. Or it is a so-called automatic function provided. In this case, the entrainment device is biased in the closing direction, optionally, the bolt is biased in the direction of the release position, and the cylinder core cooperates with the entrainment device in the opening direction.

The predetermined application of force is to be understood as a force application of the lock cylinder or of the cylinder core which is greater than the axial application of force during normal operation of the lock, that is to say when the lock is actuated by the authorized user by means of the associated identification means (for example key). In particular, said predetermined force is sufficient to move the lock cylinder or said part thereof from the operating position to the sabotage position.

As a longitudinal axis of the lock cylinder is generally to understand the axis of rotation of the cylinder core.

In order to fix the lock cylinder or the part thereof in the operating position at least in the axial direction in the operating position during normal operation, fixing means can be provided which can be overcome by said predetermined application of force by the lock cylinder or the part thereof.

For example, the fixing means may be formed as at least one fixing lug of the lock housing for the lock cylinder in order to achieve an attachment of the lock cylinder in the lock housing preferably made of zinc die-cast or plastic. A fixation can also be achieved by a press fit or a frictional engagement between the lock housing and the lock cylinder. alternative or in addition, a wall portion may be provided for the cylinder core, wherein the wall portion is formed at an axial end of the lock cylinder to fix the cylinder core in the operating position.

Preferably, the fixing means, in particular the said fixing projection and / or the wall section provided at the axial end of the lock cylinder, are designed to disengage or break upon reaching the predetermined application of force. The fixing then serve as predetermined breaking points, which yield upon reaching the predetermined application of force and clear the way for an axial movement of the lock cylinder or the part thereof.

As an alternative or in addition to the fixing means, retaining means may also be provided which, in the operating position, in particular in the region of the receiving clearance, adjoin the latch and hold, guide and / or support it, wherein the holding means can be overcome by the predetermined force application from the latch.

The retaining means may comprise at least one retaining lug of the lock housing for the bolt. Preferably, in the presence of two bars for each of the bars a separate holding approach is provided.

Preferably, the holding means are adapted to break off upon reaching the predetermined application of force in order to allow penetration of the area of the receiving space located part of the bolt and / or the lock cylinder or the part thereof in the receiving space.

It is also advantageous if the lock housing has retaining means which are designed to lock the lock cylinder or the part thereof to keep in the sabotage after putting it, ie it is ensured that the lock cylinder or the part thereof is no longer traceable to the operating position in which a drive-effective coupling of the bolt with the cylinder core could be restored under certain circumstances.

The retaining means may for example be formed as a taper of the cavity of the lock housing, in which the lock cylinder is inserted in the operating position to achieve a displacement between the lock cylinder and the lock housing when moving the lock cylinder in the sabotage. In principle, it is preferred if, in the sabotage position, the lock cylinder assumes a clamping seat in the lock housing.

According to one embodiment of the invention, the lock has locking means which in the sabotage position of the lock cylinder or part thereof prevent the lock from moving from the lock position to the release position, i. the movement of the bolt is blocked.

This can be achieved, for example, in that, in the sabotage position of the lock cylinder or of the part thereof, the bolt is in operative connection with a stop section of the lock housing. The stopper portion is in this case in the path of movement of the bolt to lock the bolt in the locked position.

When moving the lock cylinder or the part thereof, the bolt can undergo a plastic deformation, ie the bolt then has in the sabotage of the lock cylinder or the part thereof a shape that is opposite to the mold, the at least one bolt in the operating position of the lock cylinder or of the part thereof, plastically deformed is. This makes it possible, in particular, to bring the latch into operative connection with said abutment portion of the lock housing.

A blockade of the movement of the bolt in the sabotage can be further achieved in that in the sabotage of the lock cylinder or the part thereof, a blocking portion of the lock cylinder prevents the latch from moving from the locking position to the release position. In this case, the displacement of the blocking portion of the lock cylinder is responsible for setting the bolt in the sabotage position of the lock cylinder or the part thereof and blocking movement to the release position. The blocking section of the lock cylinder is preferably an outer section of the cylinder housing of the lock cylinder.

According to another embodiment of the invention, at least one coupling portion of the driving device and at least one associated coupling portion of the bolt are decoupled from each other in the sabotage of the lock cylinder or the part thereof. By the axial displacement of the lock cylinder or the part thereof, the coupling portion of the driver and the associated coupling portion of the bolt can be disengaged to disable the drive-effective coupling of the bolt with the cylinder core, so that the cylinder core turns empty relative to the bolt.

According to yet another embodiment of the invention, the drive-effective relationship of the driver device is achieved to the cylinder core in the sabotage. This can be achieved, for example, in that the entrainment device, which in the operating position is preferably fixedly connected to the rotatable cylinder core, is separated into two fragments breaks, the one fragment is connected to the cylinder core and the other fragment is connected to the latch. The associated with the cylinder core fragment of the driver is then due to the axial displacement of the cylinder core axially offset from the connected to the latch fragment of the driver, so that the cylinder core rotates empty relative to the bolt. Alternatively, a loosening of the drive-effective relationship of the driver device to the cylinder core but also be achieved in that the driver is made in two parts, the two parts in the operating position of the cylinder core drivingly and in the axial direction releasably engage each other, and wherein the one part of the driver rotatably connected to the cylinder core and the other part of the driver is coupled to the latch.

Preferably, the receiving space in the direction of the longitudinal axis of the lock cylinder has a smaller extent than the lock cylinder. The lock cylinder or the part thereof in this case only partially immersed in the receiving space, so that a lock with a small overall depth in the region of the lock cylinder can be realized.

The entrainment device can be arranged in the axial extension of the cylinder core and / or coaxially with the cylinder core.

According to one embodiment of the invention, the at least one latch is articulated to the driver device, for example via a drive cam formed eccentrically on the carrier device. In particular, two bars are provided, wherein the entrainment device then has two eccentrically arranged driving cam, on each of which one of the two bars is articulated.

According to another embodiment of the invention, in the operating position of the lock cylinder or part thereof, the latch is biased towards the driver and engages a contact peripheral region of the driver which is eccentric (e.g., elliptical or oval) with respect to the axis of rotation of the driver. By turning the cylinder core and thus the driver device, consequently, the distance of the present at the driver end of the bolt can be changed to the longitudinal axis of the lock cylinder, whereby a movement of the bolt between the release position and the locking position is made possible.

Preferably, the direction of movement of the bolt is perpendicular to the longitudinal axis of the lock cylinder. In principle, it is also possible that the latch usually designed as a locking bar has a ring-like shape for rotation about a center, for example, to be used in a padlock with rotary latch (eg series "Diskus" (registered trademark) of ABUS August Bremicker Söhne KG ).

It is also advantageous if the bolt is formed at its end facing the driver device as a bolt plate and / or at its end facing a locking portion as a bolt block. The solid bolt block is then intended to engage in a counter-locking element of the lock to be locked in order to ensure a robust locking. However, in the area of the entrainment device, the latch does not need to be so solid, so that weight can be saved. In addition, a locking plate is easier to deform laterally, whereby the explained production of an operative connection between the latch and the said stop portion of the lock housing in the axial displacement of the lock cylinder or the part thereof is simplified.

Further embodiments of the invention are set forth in the subclaims, the description and the drawing.

The invention will now be described by way of example only with reference to the drawings.

a cross-sectional view of a lock according to a third embodiment of the invention, in the region of a lock cylinder.

This in Fig. 1 illustrated U-lock according to the invention has a lock body 11 and an attachable thereto lock bracket 13, which is shown only in the region of its two strap ends. The U-lock can be used, for example, to lock a bicycle or secure it to another object, such as a bicycle stand. Fig. 1a shows a cross-sectional view of the U-lock, whereas in Fig. 1b the padlock off Fig. 1a shown in a cutaway perspective view and an in Fig. 1a shown outer lock housing 15 is omitted.

In Fig. 1 the U-lock is shown in a locking position, in which the two ends of the lock bracket 13 are respectively inserted into an associated U-bracket 17 of the lock body 11. For locking the lock bracket 13 on the lock body 11, two bolts 19 are provided, which are arranged in an inner lock housing 21 of the lock body 11 slidably in the longitudinal direction and each projecting into one of the two Bügelendaufnahmen 17. There, the latch 19 engage in trained at the two ends of the lock bracket 13 bolt receptacles 23 to secure the lock bracket 13 against removal from the lock body 11. The latch 19 are formed at their respective ends, with which they each engage in the associated latch receptacles 23 of the lock bracket 13, as a solid latch block 25, so that a stable locking is realized.

The bolt 19 are arranged by means of a center of the lock body 11 in the inner lock housing 21 arranged lock cylinder 27 between the in Fig. 1 shown locking position and a release position (not shown) movable, wherein in the release position, the two bars 19 are withdrawn from the bolt receptacles 23 of the lock bracket 13. The direction of movement of the two latches 19 in each case runs perpendicular to the longitudinal axis 29 of the lock cylinder 27.

The lock cylinder 27 has a cylinder housing 31 and a cylinder core 33 rotatably mounted in the cylinder housing 31. The cylinder core 33 is in rotationally fixed relation to a driver 35, which is arranged in the axial extension of the cylinder core 33 and coaxial with the cylinder core 33. The driver 35 may be an integral part of the cylinder core 33 or otherwise connected in a rotationally fixed manner (for example by positive engagement) with the cylinder core 33. Alternatively, a so-called automatic function can be realized.

The driver 35 has two to the longitudinal axis 29 of the lock cylinder 27 each eccentrically arranged driver cam 37, on each of which one of the two bars 19 is hinged, wherein the latch 19 are formed at their the driver 35 facing ends in each case as a latch plate 39. Thus, the latch 19 are respectively drivingly coupled via the driver 35 with the cylinder core 33, so that by a rotation of the cylinder core 33, the latch 19 are each movable between the release position and the locking position.

The lock cylinder 27 is arranged in a lock cylinder receptacle 41. The lock cylinder receptacle 41 is limited at its end facing the bolts 19 by two fixing lugs 43 of the inner lock housing 21, in each of the two possible positions of the lock cylinder 27 in the lock body 11, the cylinder housing 31 and thus the lock cylinder 27 against axial movement along the To secure longitudinal axis 29 of the lock cylinder 27. The fixing lugs 43 act as predetermined breaking points, i. from reaching a predetermined, exerted on the lock cylinder 27 axial force, such as occurs in a break-in attempt by breaking a breaking tool in the keyway of the cylinder core 33, the fixing lugs 43 break off and give the lock cylinder 27 for axial movement along the longitudinal axis 29 of the lock cylinder 27 free ,

The axial movement is thereby made possible that in the axial extension of the lock cylinder 27 within the outer lock housing 15, a receiving space 45 is formed, in which the lock cylinder 27 and especially the hinged to the lock cylinder 27 ends of the bolt 19 can dip when the bolt 19 are in the locked position shown. The lock cylinder 27 can thus from an operating position, as they are in Fig. 1 is shown, by overcoming the respective relevant Fixieransatzes 43 in a sabotage (not shown) are added.

In addition to the two fixing lugs 43 two retaining lugs 47 are further formed on the inner lock housing 21, wherein in Fig. 1 only a holding lug 47 is shown. The two holding lugs 47 are each in the receiving space 45 before, each associated with one of the two hinged to the driver 35 ends of the latch 19 and adjacent thereto, wherein each of the hinged to the driver 35 ends of the latch 19 in the region of the associated Holding approach 47 ends, so that immersion of these ends of the bolt 19 in the receiving space 45 due to an axial displacement of the lock cylinder 27 in the direction of the receiving space 45 is basically possible. The retaining lugs 47 also act as predetermined breaking points, 27 break off on reaching the predetermined axial force along the longitudinal axis 29 of the lock cylinder 27 due to the force exerted by the hinged to the driver 35 ends of the bolt 19.

As a result, these ends of the bolts 19 can be bent by plastic deformation in each case around an associated support portion 49 of the inner lock housing 21 into the receiving space, wherein in Fig. 1 only a single such support portion 49 is shown. As a result, a clamping connection is created between the respective latch 19 and the respective support section 49 of the inner lock housing 21, which ensures that movement of the respective latch 19 from the locking position into the release position is at least made more difficult. Above all, due to the illustrated bending, the respective end of the two latches 19 is provided from the movement plane provided in normal operation in the direction of a respective stop section 50 of the inner lock housing 21 offset, wherein in Fig. 1b only one of the two stop portions 50 is shown. Each abutment portion 50 is formed by an end face on which the respective holding lug 47 is formed, as long as it has not been canceled. The stopper portions 50 thus serve as stops for the bolt ends, blocking the bolt 19 against displacement from the locking position into the release position, ie the bolts 19 are fixed in the sabotage position of the lock cylinder 27.

In order to keep the lock cylinder 27 in the sabotage position, the lock cylinder receptacle 41 has a taper 51 in the region of its end facing the bolts 19. In an axial movement of the lock cylinder 27, this is jammed in the taper 51, wherein the taper 51 acts as a retaining means to return the lock cylinder 27 in the in Fig. 1 To prevent shown operating position.

The padlock according to the invention is thus constructed such that in a violent attempt to break the lock cylinder 27 passes from an operating position in a sabotage, in which a displacement of the latch 19 is prevented in the release position by a violent rotation of the cylinder core 33.

The following are based on the FIGS. 2 and 3 described further embodiments of the invention, wherein the same or similar components are provided with the same reference numerals.

The in Fig. 2a in a cross-sectional view and in Fig. 2b in a plan view shown detail of the U-lock according to the second embodiment of the invention shows a lock cylinder 27 which comprises a cylinder housing 31 and a cylinder core 33 rotatably mounted therein. A driver 35 of the lock cylinder 27 is rotatably connected to the cylinder core 33 in the axial extension of the cylinder core 33 via a driving lug 53 of the cylinder core 33. The driver 35 has the shape of an oval cylinder, as in Fig. 2b is recognizable.

In addition, two with respect to the lock cylinder 27 opposing bolt 19 are provided, which are each biased in the direction of the driver 35, as can be seen with reference to the arrows 55. In the in Fig. 2 shown locking position, the bolt 19 are at a contact peripheral portion 59 of the driver 35, wherein the major semi-axes of the driver 35 are aligned with the locking shafts 19. To move the latch 19 in a release position (not shown), the cylinder core 33 is rotated by 90 ° about the longitudinal axis 29 of the lock cylinder 27, so that then the small half-axes of the driver 35 are aligned with the locking shafts 19.

Will now try that in Fig. 2 shown lock by a predetermined application of force in the axial direction of the lock cylinder 27, the lock cylinder 27 moves with the driver 35 along a direction of movement 57, which corresponds to the direction of the longitudinal axis 29 of the lock cylinder 27, from the in Fig. 2 shown operating position in a receiving space 45 so far into that the original position of the driver 35 through the upper end 63 of the cylinder housing 31 of the lock cylinder 27, which defines a blocking portion, is taken (sabotage). Since the lock cylinder 27 is formed in a circular cylindrical shape at its upper end 63 and the diameter in the region 63 approximately corresponds to the diameter of the driver 35 in the region of the major half-axes, the bolt 19 remain unchanged in the sabotage in the in Fig. 2 illustrated locking position. However, the latch 19 are decoupled from the driver 35 in the sabotage.

If the cylinder core 33 is rotated in the sabotage position, the driver 35 also rotates. The bolt 19 are in the sabotage but no longer on the contact peripheral portion 59 of the driver 35, but on the cylinder housing 31 of the lock cylinder 27, so that the bolt 19 in their in Fig. 2 remain shown locking position.

Consequently, the circular cylindrical cylinder housing 31 in the plane of movement of the bolt 19 replaces the oval cylindrical cam 35, so that regardless of the rotational position of the cylinder core 33, the bolt 19 are blocked against movement into the release position. The bars 19 are not deformed in this embodiment of the invention.

The in Fig. 3 shown section of a lock according to the third embodiment of the invention comprises a lock cylinder 27 which has a cylinder housing 31 and a cylinder core 33 rotatably mounted therein. The cylinder core 33 is rotatably connected via a driving lug 53 of the cylinder core 33 with a driver 35. The driver 35 forms an end wall for the cylinder core 33. A rotation of the cylinder core 33 results in a corresponding rotation of the driver 35. The driver 35 is laterally coupled to at least one latch (not shown), the latch being between a release position and a latch position is movable.

Is the cylinder core 33, which in Fig. 3 is shown in an operating position, acted upon by a sufficient force along the longitudinal axis 29 of the lock cylinder 29, the driver 35 breaks at a circumferential predetermined breaking point 61, so that the inner part 65 of the driver 35th and an upper end of the cylinder core 33 can be immersed in a receiving space 45 arranged in the axial extension of the lock cylinder 27 (sabotage position, not shown). The broken outer edge of the driver 35, with which the latch cooperates, remains in its position between the cylinder housing 31 and a portion of an outer lock housing 15. In sabotage thus the rotationally fixed relationship of the driver 35 is released to the cylinder core 33. The in Fig. 3 For example, the mechanism shown can also be used in a padlock with a rotary latch.

Alternatively, it is also possible that the driver is already carried out in two parts, wherein the two parts rotatably in an operating position of the cylinder core, but in the axial direction releasably engage each other, for example via a toothing, and wherein the one part of the driver rotationally fixed or otherwise drivingly connected to the cylinder core and the other part of the driver is coupled to the latch (not shown). Such a lock can analogously to the lock according to Fig. 3 be formed, wherein only the portion 61 is not designed as a predetermined breaking point, but as an area in which the two parts of the driver engage releasably drive-effective one another.

Essential in all the embodiments described above is that in the axial extension of the lock cylinder, a receiving space is formed, which allows axial movement of the lock cylinder or the cylinder core in a tamper position to put the driving effective coupling between the cylinder core and at least one bar out of function.
