Definitions

  • the present invention relates to an articulated lock according to the respective preamble of claim 1 and claim 15.
  • Such an articulated lock is known from EP 1 353 029 A1 known.
  • the articulated lock comprises a lock body and an articulated bar bracket, the lock body accommodating a locking cylinder and a bolt which can be moved through the locking cylinder selectively from a closed position into a release position, and wherein the articulated bar bracket comprises a plurality of articulated bars articulated to one another, a first end of the articulated bar bracket one has elongated locking rod which can be inserted into an insertion opening of the lock body and locked in the lock body by means of the bolt.
  • Such an articulated lock is used, for example, to secure a two-wheeler to a bicycle stand, a lamppost or the like.
  • the articulated rods of the articulated bar bracket which are articulated one behind the other or in a row, are folded apart, and the locking bar, which forms the free end of the articulated bar bracket, is locked on the lock body, in order to thereby form a closed loop.
  • This closed loop can, for example, encompass a frame section of the two-wheeler and the bicycle stand, lamppost or the like, or the articulated bar bracket only surrounds one rim of the two-wheeler in order to prevent unauthorized persons from moving away.
  • the articulated bars can be folded into a compact arrangement, it being possible in particular to lock the locking bar in the lock body even when the articulated bar bracket is in the folded state, the articulated bar bracket maintaining the folded shape.
  • a disadvantage of the known articulated locks is that, in order to insert the locking rod into the insertion opening of the lock body, the bolt must be moved into the release position by means of the locking cylinder and the appropriate key. The bolt must then be brought into the closed position using the key in order to lock the locking rod in the lock body. Both the insertion of the locking rod into the lock body and the locking of the locking rod in the lock body therefore require manual operation.
  • the lock body also houses a pretensioning device which pretensions the bolt into the closed position, the bolt being temporarily movable from the closed position into the release position against the pretension by inserting the locking bar into the lock body, the pretensioning device being adapted to return the bolt to to move the closed position when the locking bar is fully inserted into the lock body.
  • the bolt is moved briefly from the closed position into the release position, so that the locking bar can be inserted into the lock body without additional movement of the locking cylinder.
  • the locking bar is inserted against a pretension of the bolt, which is generated by means of the pretensioning device.
  • a section of the locking bar intended for insertion into the lock body is inserted into the lock body, ie when the locking bar is fully inserted into the lock body, the bolt is pushed back into the closed position by the pretension, whereby the locking bar is locked in the lock body. Removing the inserted locking rod from the lock body is not possible in the closed position.
  • the locking bar can only be removed from the lock body again when the bolt is moved from the closed position into the release position by the locking cylinder.
  • the articulated lock according to the invention thus enables an automatic function for locking the inserted locking rod without actuating the locking cylinder.
  • the handling of the articulated lock according to the invention when locking is thus simple and inexpensive, since only the locking bar has to be inserted into the lock body and is automatically locked there.
  • the bolt is designed as a rotary bolt.
  • the rotary bolt is rotatably mounted on an outer surface of the locking cylinder.
  • the rotary latch can rest on an outer lateral surface of the locking cylinder, in particular on a cylindrical lateral surface of a cylinder housing, as a result of which the locking cylinder forms a bearing surface for the rotary latch.
  • the rotary bolt can have the shape of a sector of a hollow cylinder, the inner surface of the hollow cylinder abutting the cylindrical outer surface of the locking cylinder. In this way, a simple storage of the rotating latch is possible.
  • the use of a rotary bolt significantly increases security against unauthorized opening of the articulated lock, since if a linearly displaceable bolt is used, the bolt could be briefly moved from the closed position to the release position, for example by a hammer blow on the lock body. However, triggering a rotary movement to bring the rotary bolt into the release position is not possible by striking the lock body with a hammer.
  • the aforementioned pretensioning device can be designed as a torsion spring.
  • the rotary latch comprises a circumferential surface with a recess, which in the release position of the rotary latch releases a movement path of the locking bar.
  • the rotary latch In the release position, the rotary latch can be positioned in such a way that the recess lies in the path of movement of the locking bar and in particular releases a locking bar elevation. If the recess is arranged in the movement path of the locking bar, the locking bar can be inserted into the lock body or pulled out of it. In the closed position, however, the recess of the rotary bolt is moved out of the path of movement of the locking rod, whereby the path of movement of the locking rod or the aforementioned security elevation is blocked and the inserted locking rod is locked in the lock body.
  • the locking bar has a locking section at a free end, which is in operative engagement with the locking bar in the locking position of the locking bar in order to lock the locking bar in the lock body.
  • the free end is defined as the end of the locking bar that can be inserted into the lock body.
  • a second end of the locking bar, which lies opposite the free end, is articulated on a hinge bar of the hinge bar bracket. The locking section can be in operative engagement with the bolt in particular when the locking bar is fully inserted into the lock body.
  • the locking section of the locking bar is preferably formed by a safety elevation, that is to say by an elevation relative to the surface of the locking bar.
  • the securing elevation is preferably provided on a broad side of the normally flat locking bar.
  • the bolt can be arranged in the closed position in such a way that it is in active engagement with the securing elevation in order to be pulled out to prevent the locking rod from the lock body by the bolt blocking the path of movement of the securing elevation and / or wedging it with the securing elevation.
  • the pretensioning device is fastened to the locking cylinder and to the bolt. This means that the pretensioning device engages both the locking cylinder and the bolt in order to clamp the locking cylinder and the bolt to one another, whereby the pretensioning device, locking cylinder and bolt can form an independent unit.
  • the biasing device can be designed, for example, as a spring.
  • the axis of rotation of the rotary bolt coincides with an axis of rotation of the locking cylinder or runs parallel to it.
  • the rotary bolt and the locking cylinder can therefore be arranged coaxially or almost coaxially.
  • the aforesaid recess runs in a tangential direction along the lateral surface of the rotary bolt with respect to the axis of rotation of the rotary bolt.
  • the rotary latch can essentially have the shape of a hollow cylinder or a sector of a hollow cylinder, the recess extending in the circumferential direction of the lateral surface of the rotary latch and extending along a certain angular range of the lateral surface.
  • the locking cylinder has a cylinder housing and a cylinder core which is rotatably mounted in the cylinder housing and which is coupled to the rotary latch in a drive-effective manner but with a backlash.
  • the cylinder core can optionally be rotated by the user by means of a key assigned to the locking cylinder.
  • the rotary bolt By a rotary movement of the cylinder core, which can be transferred to the rotary bolt, the rotary bolt can be rotated about its axis of rotation in order, for example, to release the path of movement of the locking rod or a securing elevation provided thereon.
  • the rotary bolt Due to the backlash, which is provided between the cylinder core and the rotary bolt, the rotary bolt can also be temporarily rotated into the release position when the locking rod is inserted into the lock body, without a rotary movement of the cylinder core being necessary. Then, due to the pretension, the rotary bolt can return from the release position into the closed position without the rotary movement of the cylinder core being necessary.
  • the cylinder core has a drive extension, the cross section of which is partly formed by a circular section and partly by a stop edge, the drive extension engaging in a coupling opening of the rotary latch, and the cross section of the coupling opening partly by a circular section, partly by a first Stop edge and is partially formed by a second stop edge which is adjacent to the first stop edge and encloses an angle different from 0 ° and 180 °.
  • a rotary movement of the cylinder core can be transmitted to the rotary latch in order to rotate the rotary latch and, for example, to change the position of the recess in the rotary latch.
  • the drive extension is an extension of the cylinder core, which is defined by a circular section delimited by a secant.
  • the drive extension is also set in rotation by a rotation of the cylinder core and transmits its rotary movement, for example, to the first stop edge of the rotating bolt.
  • the coupling opening can be formed by a circular section into which a triangular stop protrudes, wherein the first stop edge can be formed by a first secant section and the second stop edge can be formed by a second secant section, which enclose an angle with one another.
  • the aforementioned torsional backlash between the cylinder core and the rotary bolt can be defined by this angle, namely in that either the mentioned first stop edge or the second stop edge of the coupling opening of the rotary bolt bears against the mentioned stop edge of the drive extension.
  • the lock body in particular the inner housing to be explained below, can furthermore comprise a stop which limits a rotary movement of the cylinder core and / or the rotary bolt in order to at least to prevent the cylinder core in the cylinder housing from over-rotating or the rotating bolt from over-rotating.
  • the locking bar can advantageously be inserted into the insertion opening of the lock body along its longitudinal axis, with an axis of rotation of the locking cylinder being oriented perpendicular to a plane which is spanned by the longitudinal axis of the locking bar (ie the direction of insertion of the locking bar) and the hinge axis of the locking bar when the locking bar is inserted into the lock body.
  • the rotary bolt can be rotated about its axis of rotation. This in turn can cause the recess of the rotary bolt to be displaced into the movement path of the locking bar, as a result of which the locking bar can be inserted completely into the lock body.
  • the aforementioned plane corresponds in particular to the plane of extension of the joint rods and the locking rod if the joint rod bracket is folded up in the manner of a folding rule and the joint rods and the locking rod lie next to one another parallel to one another.
  • An alignment of the lock cylinder, in which the direction of insertion of the key runs perpendicular to the plane mentioned, is also advantageous in the following way: when not in use, the articulated lock can be kept in an associated lock pocket during transport, which is typically mounted on the frame tube of a bicycle in this way, that the longitudinal axes of the joint rods run parallel to the longitudinal axis of the frame tube and the broad side of the joint rod package formed faces the frame tube (cf., for example, that in FIG DE 20 2005 013 390 U1 shown lock pocket).
  • the insertion opening of the key on the lock body is oriented perpendicular to the aforementioned plane, the key can remain inserted in the lock cylinder during the transport of the articulated lock without the key protruding into the range of movement of the cyclist and thereby interfering with the cyclist's movements.
  • the locking bar can be pivoted laterally into the insertion opening of the lock body, an axis of rotation of the locking cylinder being aligned parallel to the longitudinal axis of the locking bar when the locking bar is inserted into the lock body.
  • the path of movement of the locking bar when it is inserted laterally into the lock body can therefore be approximately perpendicular to a plane in the area of the lock body, which plane is defined by the axis of rotation of the rotary bolt and the longitudinal axis of the locking bar in the fully inserted state.
  • the bolt can also be designed as a snap bolt which projects into the movement path of the locking bar.
  • the snap bolt can be temporarily pushed back from an end face of the locking bar and, after the locking bar has been fully inserted into the lock body, engage in a recess in the locking bar or can engage behind a locking protrusion of the locking bar in order to lock the locking bar in the lock body.
  • the snap bolt and / or the end face of the locking bar can comprise an inclined surface through which the locking bar is pushed back when the locking bar is inserted into the lock body.
  • a security survey on the locking bar is not absolutely necessary, since an intervention of the bolt - as explained - can for example be provided in a recess of the locking bar.
  • the locking bar has at least one protective elevation, which — viewed along the longitudinal axis of the locking bar — is provided between the insertion opening of the lock body and the bolt when the locking bar is fully inserted into the lock body.
  • a protection elevation serves to protect against manipulation of the bolt from the outside, for example if an attempt is made to move the bolt in the direction of its release position through the insertion opening of the lock body using a flat tool.
  • the protection bar of the locking bar prevents access to the effective area between the bolt and the locking bar.
  • the protection elevation can be designed as an increase in relation to a broad side of the normally flat locking bar.
  • the protection elevation can in particular be provided on that side of the locking bar which faces the bolt within the lock body.
  • the protection elevation can be provided between the insertion opening of the lock body and the aforementioned security elevation of the locking bar when the locking bar is fully inserted into the lock body.
  • a particularly cost-effective production of the articulated lock can be achieved in particular in that the lock body has a one-piece inner housing with two bearing openings on two opposite sides, the locking cylinder having a cylinder housing and a cylinder core rotatably mounted in the cylinder housing (in particular the cylinder housing and cylinder core already mentioned ), wherein the locking cylinder is caught between the two opposite sides of the inner housing, and wherein the cylinder core in the two bearing openings of the inner housing is rotatably supported.
  • the one-piece inner housing can be made of metal as a stamped and bent part.
  • the one-piece inner housing mentioned has at least one bent retaining tongue which fixes the cylinder housing against rotation.
  • the cylinder housing can be rigidly fixed in the inner housing in a particularly simple manner.
  • Two holding tongues of this type are preferably provided, which engage on two different sides of a flange section of the cylinder housing.
  • the lock body has a sleeve which surrounds the aforementioned one-piece inner housing in order to additionally stabilize it.
  • the sleeve is preferably made of metal and fully opened at one end in order to be able to pull the sleeve onto the inner housing.
  • the sleeve can be fixed to the inner housing by positive locking, for example by selective deformation and corresponding engagement of the inner housing at several points along the circumference.
  • a second end of the hinge rod bracket is permanently attached to the lock body.
  • the hinge bar bracket can be rotatably attached to the lock body, whereby the lock body can be pivoted relative to the hinge bar bracket.
  • the rotatable attachment of the second end of the hinge rod bracket to the lock body can be provided in the region of the longitudinal axis of the lock body, ie the axis of rotation coincides with the longitudinal axis of the lock body or is only slightly spaced therefrom to maximize the length of the closed loop.
  • the plastic jacket of the first end of the hinge bar bracket is of a different color than that of the second end of the hinge bar bracket, which is articulated to the lock body. If the lock body and the second end of the hinge bar bracket are of the same color, the color-distinguishable first end of the hinge bar bracket already visually indicates to the user which end of the hinge bar bracket can be detached from the lock body.
  • the respective plastic jacket of the locking bar and all of the hinge bars can be designed in a first color, while the hinge bar corresponding to the second end of the hinge bar bracket and the lock body are designed in a different second color.

  • the hinge bar bracket 14 has a plurality of hinge bars 16, one of which is designed as a locking bar 18.
  • the joint rods 16 and the locking rod 18 are each formed flat and preferably consist of steel, which is surrounded by a plastic jacket 20, in order to avoid damage to the two-wheeler to be locked.

Since the recess 70 of the turning bolt 54 is turned away from the securing elevation 76 in the closed position , The safety elevation 76 cannot pass between the lock body reinforcement 38 and the rotary bolt 54. The locking bar 18 is thus locked in the lock body 12.
  • the protective elevation 78 counteracts manipulation of the rotational position of the rotary bolt 54 through the insertion opening 34 of the lock body 12.
  • the protection elevation 78 namely prevents a flat tool from being inserted into the insertion opening 34 along the locking rod 18 in order to urge the rotary latch 54 in the direction of its release position inside the lock body 12.
  • the authorized user wants to remove the locking bar 18 from the lock body 12, for example in order to detach his two-wheeler from a bicycle stand, he inserts the key 32 into the locking cylinder 40. Subsequently, the cylinder core 50 is rotated with the key 32 (in FIG Fig. 3a clockwise), by which the drive extension 42 is set in a rotary motion. As a result, the stop edge 46 of the cylinder core 50 drives the first stop edge 62 of the coupling region 58 of the rotary bolt 54 and also sets the rotary bolt 54 in rotation (in Fig. 3a clockwise).
  • the recess 70 is brought into the movement path of the locking bar 18 (release position of the rotary bolt 54), as a result of which the securing elevation 76 is released and can pass between the lock body reinforcement 38 and the rotary bolt 54.
  • the locking bar 18 can thus be pulled out of the lock body 12.
  • the locking bar 18 can be so short that the hinge bar bracket 14 can be folded into a common plane of extension of the hinge bars 16 and the locking bar 18 without the locking bar 18 being inserted into the lock body 12.
  • the articulated lock 10 can be stored or transported in the folded state, it being possible for the locking bar 18 to be inserted into the insertion opening 34 of the lock body 12 for a subsequent closing of the articulated lock 10, without the locking bar 18 first being released from the lock body 12 by means of the key 32 must become. Since - as explained - no key actuation of the locking cylinder 40 is required to lock the locking rod 18 on the lock body 12, the use of the articulated lock 10 is thus particularly convenient.
