Abstract

The lock, and especially a double-wheel lock for a joint rod assembly (13a-13c), has a lock body (11) and a plug (15) to be locked to it. The lock body has a cylinder, a bolt (35) coupled to it and a plug holder (27), to take the inserted plug. The cylinder and the plug in the holder lie along a common lock longitudinal axis (67). The bolt can be moved selectively between a locked and a released position. In the locked setting, the locking sections (41,57) of the bolt and the plug lie together on a flat, on a plane at right angles to the longitudinal axis.

Description

The invention relates to a lock, in particular a two-wheel lock, having at least one lock body and a lockable thereto, the lock body has a lock cylinder, with the lock cylinder - at least indirectly - coupled latch and a Klobenaufnahme, into which the block inserted or out of the the block is removable, and wherein the lock cylinder and located in the Klobenaufnahme block are arranged along a common lock assembly axis.

This lock type is thus characterized by a linear arrangement of lock cylinder and clamp, wherein the block is arranged along an extension of the lock cylinder or a rotational actuation axis of the lock cylinder. For example, it is known for such a linear arrangement, to couple a arranged at an end face of the lock cylinder rotary drive element with a rotatable carrier cage. The Mitnehmerkäfig forces, depending on the rotational position, stored in a storage pan steel balls to a radial entry into the Klobenaufnahme or to a radial retreat from the Klobenaufnahme. As a result, the steel balls for locking the block cooperate with a circumferential groove on the block or soft for unlocking from this circumferential groove back. The structure of this castle is undesirable consuming.

From US 4,075,878 a lock is known in which a lock cylinder drives a rotary latch to a rotational movement, wherein the rotary latch optionally engages laterally in an annular groove of a block.

US 6,055,832 describes a lock with a lock cylinder, a rotating bolt and a clamp, which are arranged along a common lock assembly axis.

It is therefore an object of the invention to provide a lock with the illustrated linear arrangement of lock cylinder and block, the at a simple and compact structure has a high stability against a violent unauthorized opening.

This object is solved by the features of claim 1.

In the case of the lock according to the invention, in each case at least one flat locking section is provided on the part of the block and on the side of the bolt. For locking the block in the clamp receiver of the lock body, these locking sections cooperate flatly, for example by abutting one another or facing one another. This surface interaction takes place along a transverse plane, in particular perpendicular to the lock arrangement axis.

This embodiment is based on the finding that a surface interaction of bolt and clamp causes a particularly high tensile stability with respect to an attempt to forcibly remove the locked block from the clamp receptacle. Due to the flat Design of the locking portion of the block and the locking portion of the bolt can be realized in the mutual locking engagement namely a high area coverage. In addition, the bolt and the clamp are claimed only on shearing. This higher tensile stability is particularly noticeable in comparison to known locks in which steel balls rest on the block for locking the block and thus ultimately only a point or linear contact between the block and the balls is realized.

In addition, since the surface cooperation takes place along a plane extending transversely to the lock arrangement axis, slippage of the tensile load-bearing block along an oblique locking surface of the bolt is avoided. Instead, it is ensured that the clamp and the bolt are subjected to a tensile load along the lock assembly axis substantially exclusively to shearing.

It should also be noted with the invention that a direction running transversely to the lock arrangement axis is to be understood as meaning a direction which is perpendicular or substantially perpendicular, in particular oblique to the lock arrangement axis.

According to a preferred embodiment of the invention, the movement of the bolt between the release position and the locking position takes place along a direction transverse to the lock arrangement axis. As a result, the surface interaction of the locking portions in the locking position can be realized particularly easily. In a conventional lock construction drives namely the lock cylinder a driver part for a rotational movement about the lock assembly axis. Such rotational movement has tangential components of movement which are perpendicular to the axis of rotation and thus to the lock assembly axis, and which thus can be easily translated into a latching movement transverse to the lock assembly axis. Thus, the lock according to the invention can ultimately be realized with a compact design of a driving and locking mechanism.

Furthermore, it is preferred; when the bar is substantially disc-shaped. By this design, the bolt - for example, as a metal disc - are made in a particularly simple manner, while at the same time have a flat and thus compact design and can be equipped with the required surface locking portion.

The movement of the bolt between the locking position and the release position can - depending on the coupling with a driver part and depending on leadership within the lock body, for example, as a curved displacement, linear displacement, pivoting, as a rotational movement about the lock assembly axis or as a combination of these types of movement. Preferably, the latch performs a combination of a turning and turning movement within the plane transverse to the lock assembly axis.

In order to bring about such a curve / rotary movement or a pure pivoting movement, the bolt can be hinged to a hinge device be, which is preferably provided with respect to the lock assembly axis in eccentric arrangement.

The release recess of the bolt can be formed by a passage opening, ie a circumferentially closed opening. In particular, in the case of a curve / rotary movement or a pivotal movement of the bolt, it is preferred if the release recess is provided on the bolt in an eccentric arrangement. As an alternative to the embodiment as a passage opening, the release recess can also be formed by a lateral indentation of the bolt, for example in the manner of a hook.

With regard to the drive of the bolt, it is preferred if the lock has a driver part, via which the bolt is coupled to the lock cylinder. Preferably, the latch on a driver portion on which the driver member engages to drive the latch to move to the locking position and / or in the release position. In particular, the latch and the driver member are coupled such that rotational movement of the driver member about the latch assembly axis translates into movement of the latch transverse to the latch assembly axis. The driver portion of the bolt may for example be formed by an end face of the bolt or - for a slotted guide - an engagement groove, which preferably extends within a transverse plane to the lock assembly axis.

Furthermore, it is preferred if the said driver part for the coupling with the bolt has at least one driver section, which is in particular designed sickle-shaped. Such a sickle or Crescent shape is particularly suitable for driving the latch to an eccentric pivoting or pivoting motion through cooperation with a catch portion of the latch. However, for this purpose, one or more driving pins, cams or pins may be provided, which engage a driver portion of the bolt.

The coupling engagement between driver part and latch can also be configured in reverse, so that ultimately a driver increase of the bolt engages in a driver recess of the driver part.

According to a preferred embodiment of the invention, the lock on a bracket, wherein a klobenseitiges bracket end connected to the clamp and a lock body side bracket end has a clasping, which is arranged on the lock body such that it engages behind the block or circumferentially engages around, if the block in the Klobenaufnahme is introduced.

In other words, a bracket is provided, which is fastened with one end to the lock body and the free end of which can be selectively locked by means of the clamp on the lock body, for example, to secure an embraced by means of the bracket object against removal. The arrangement explained causes a particularly stable connection of the lock body side bracket end with the clamp in the event of a violent tensile load. In this case, a gripping around the clamp along a closed circumference may be provided, for example by the Umgreifungseinrichtung an eyelet of a Gelenkstabbügels or a Starrbügels, or a loop of a Panzerkabelbügels or having a cable bracket. Alternatively, a gripping behind along an open circumference can take place, so in the manner of a hook.

This development is based on the finding that in many cases the violent breaking of a lock strap, the weak point at the connection of the strap ends on the lock body, as a Angriffszugbelastung the bracket is transmitted to this connection and there - despite locking the block on the lock body - to an undesirable Loosening the connection of the temple ends can lead.

Since in the described embodiment, in the event of a violent pulling apart of the strap, both strap ends ultimately engage the clamp, such an attack pull load is transmitted mainly or exclusively to the clamp, which can be solid and particularly stable. In contrast, such a Zugszugbelastung the strap is not or only slightly transferred to a locking mechanism of the castle, so that it is not easily damaged by a violent pulling apart of the bracket.

Since an attack tension load on the bracket is hardly transmitted to the locking mechanism of the lock, a comparatively compact construction of the locking mechanism and thus of the lock body is also possible.

For the described development, it is not absolutely necessary that during the normal, legitimate use of the castle, the lock body side bracket end always rests against the block. Instead it is to achieve the described advantageous load transfer to the block only required that the lock body side bracket end attacks in the event of a Angriffszugbelastung the bracket on the block. For this purpose, it is preferred that during a normal, legitimate use load of the bracket, the lock body side bracket end is rigidly secured to the lock body. Alternatively, however, it is also possible that the lock body-side end bracket is movably attached to the lock body, for example, slidably, so that this strap end in the event of any tensile load of the strap immediately attacks the block, if this is introduced into the Klobenaufnahme.

The said bracket may be, for example, a cable, a catenary cable, a chain, a rod bracket or a Gelenkstabbügel.

Preferably, the clip-side and the lock-body side bracket end are attached to the block or lock body in such a way that the strap ends engage in an opposing pull of the bracket in opposite directions, in particular diametrically opposite to the block, provided the block is in the block receiver. In such an embodiment, the attack tensile load can be particularly effectively absorbed by the block, so that the lock is particularly stable against a violent opening of the bracket.

In the illustrated embodiment, it is possible that the cloverleaf end of the strap is permanently connected to a separate block or formed integrally with a clamp. However, it is preferred if Also, the claw-side bracket end has a clasping device which engages behind the claw in a manner or circumferentially surrounds, as already explained in connection with the lock body side bracket end.

Figs. 1 to 5 show an inventively designed articulated lock. As can be seen from the side view of FIG. 1, this articulated bar lock has a lock body 11 to which a joint rod 13a is rigidly fastened. On the joint rod 13 a successively four joint rods 13 b and a joint rod 13 c are each pivotally and slightly articulated articulated. The joint rod 13c is provided with a clamp 15, of which in the closed state of the lock according to FIG. 1, only one mounting base 17 can be seen.

The constituents of the articulated bar lock according to FIG. 1 explained below and their respective configuration can be seen in particular from the exploded views according to FIGS. 2 and 3.

A lock cylinder housing 19 has the shape of a hollow truncated cone surrounding a lock cylinder receptacle 21, which serves to receive a lock cylinder, not shown in the figures of a conventional structure. The lock cylinder housing 19 also has a lateral Fixieraufnahme 23rd

A driver part 25 essentially has the shape of a hollow cylinder which surrounds a clamp receptacle 27. On an end face of this hollow cylindrical shape, the driver part 25 has a coupling opening 29 for enabling a coupling with said lock cylinder. At the opposite end face, the lateral surface of the driver part 25 is extended along approximately half the circumference to a protruding driver portion 31 which is sickle-shaped in cross-section (see Fig. 4c and 5c). The driver member 25 also has along a the driver portion 31 opposite portion of the outer circumferential surface a rotary clearance recess 33rd

A latch 35 has the shape of a circular disk with a circular passage opening 37 and a lateral Anlenkaussparung 39. The passage opening 37 is arranged eccentrically with respect to the circular shape of the bolt 35.

An adjacent to the passage opening 37 surface portion of the bolt 35 serves as a locking portion 41, as will be explained below.

Furthermore, a longitudinal cylindrical fixing pin 43 and a fastening ring 45 are provided. In addition, FIGS. 2 and 3 show that the free end 47 of the joint rod 13c has a fastening opening 49 serving as a gripping device.

The block 15 has a cylindrical neck neck 51, at one end of the mounting base 17 is formed. The other end of the Klobenhalses 51 is formed as a Klobenkopf 53. This is separated from the Klobenhals 51 by a locking recess 55 in the form of a circumferential groove. The klobenkopfseitige boundary surface of the locking recess 55 forms an annular flat locking portion 57 of the block 15th

In the illustration according to FIGS. 2 and 3, the free end 59 of the joint rod 13 a is inserted into the lock body 11. This articulation rod end 59 has a fastening opening 61 serving as encompassing device as well as a fixing opening 63 (compare FIG. 2). In addition, the lock body 11 is frontally provided with a keyhole 65 (see Fig. 3).

The lock body 11, the lock cylinder housing 19, the lock cylinder provided therein, the driver part 25, the latch 35, the mounting ring 45 and the clamp 15 are provided in the closed state of the articulated bar lock shown (FIG. 1) for arrangement along a common lock arrangement axis 67. In particular, the arrangement of the clamp 15 in extension of the provided within the lock cylinder housing 19 lock cylinder characterizes the characteristic linear structure of the lock shown. As shown in FIGS. 2 and 3, this Schlossanordnurigsachse 67 simultaneously forms the axis of symmetry of the rotationally symmetrical Klobenhalses 51 with the locking recess 55 of the block 15. Further, the Schlossanordnungsachse 67 coincides with the Drehbetätigungsachse - not shown in the figures - lock cylinder, and they also corresponds to the axis of rotation of the driver 25, as will be explained below.

4 and 5 show the arrangement of said components in the assembled and closed state of the articulated bar lock, for a release position and a locking position of the bolt 35th

In the assembled state, the lock cylinder housing 19 with the locking cylinder not shown in the figures, further the driver part 25 and the bolt 35 along the lock assembly axis 67 within the lock body 11 and there due to the introduced laterally into the lock body 11 hinge rod end 59 of the joint rod 13a caught. This joint rod 13a in turn is fixed in the lock body 11 by the fixing pin 43 against a lateral removal from the lock body 11. The fixing pin 43 is inserted through the fixing opening 63 of the joint rod 13a, through the Anlenkaussparung 39 of the bolt 35 and through the rotary clearance recess 33 of the driver 25 in the Fixieraufnahme 23 of the lock cylinder housing 19. The fixing pin 43 thus also secures the lock cylinder housing 19 against rotation about the lock arrangement axis 67.

The clamp 15 is fixed to the end 47 of the hinge rod 13c, namely by the Klobenhals 51 is guided through the mounting hole 49 and the mounting base 17 thus abuts against the hinge rod 13c. On the opposite side of the hinge rod end 47 of the mounting ring 45 is fixed - for example, by a radial constriction - on the Klobenhals 51, so that the block is caught in the mounting hole 49. The mounting base 17 and the fastening ring 45 are spaced apart from each other in such a way that the joint rod 13c is axially displaceable relative to the clamp 15 and / or slightly pivotable with respect to the lock arrangement axis 23. This facilitates the handling of the bracket. If the block 15, as shown in Fig. 4a, 4b, 5a and 5b, is introduced with the pawl head 53 in the Klobenaufnahme 27 of the driver 25, the mounting ring 45 forms a positive connection with a ring receiver 69, which is formed by the annular end face of the lock body 11.

The articulated bar lock shown in FIGS. 1 to 5 functions as follows:

If the latch 35 is in the release position (FIGS. 4 a, 4 b and 4 c), the clamp 15 can be removed from the clamp receptacle 27 along the lock arrangement axis 67. The hingedly connected joint rods 13a, 13b, 13c can then be guided around or through an object to be secured, for example a bicycle. The hinge rod 13c is then guided back to the lock body 11 to insert the clamp 15 along the lock assembly axis 67 into the clamp receiver 27. Finally, the block 15 is locked in this position, as will be explained below. The operation of the articulated bar lock shown thus corresponds substantially to that of, for example, a cable lock, the hinge rods serve as a lock bracket.

The locking of the clamp 15 at the lock shown is done as follows:

The latch 35 can be brought into a release position, as shown in Fig. 4a, 4b, 4c. In this release position, the passage opening 37 of the bolt 35 with respect to the Klobenaufnahme 27 of the Mitnehmerteils 25 and with respect to the mounting hole 61 of the hinge rod end 59 is aligned such that the Klobenaufnahme 27 extended to a cylindrical cavity and thus released for receiving the block 15 with the Klobenkopf 53 is. To the block 15 in this position too lock, the bolt 35 is moved perpendicular to the lock assembly axis 67, so that it partially protrudes into the Klobenaufnahme 27 and its axial extension and thus also in the locking recess 55 of the block 15 engages (see Fig. 5a, 5b, 5c). This transfer of the bolt 35 in the locking position is done as follows:

By means of a key or other identification means, which is inserted through the keyhole 65 of the lock body 11 in the lock cylinder housing 19 located in the lock cylinder, the lock cylinder is rotationally actuated. Thereby, a rotary drive member of the lock cylinder, which engages in the coupling opening 29 of the driver 25, is rotated about the lock assembly axis 67. This leads to a rotational movement of the driver 25 about the lock assembly axis 67. For this purpose, the driver member 25 is rotatably supported, namely by the end faces of the driver 25 on the lock cylinder housing 19 and the hinge rod end 59 and the outer circumferential surface of the driver 25 on the inner surface of the Rest against the lock body 11. This rotational actuation of the driver 15 is not hindered by the fixing pin 43, since this is within the rotary clearance recess 33.

The driver part 25 transmits this rotational movement to the bolt 35 in such a way that it performs a curve / rotational movement within a plane perpendicular to the lock arrangement axis 67. For this purpose, a portion of the peripheral end face of the disk-shaped bolt 35 is provided as a driver portion 71, with which cooperates the inner peripheral side of the crescent-shaped cam portion 31 of the driver part 25. The latch 35 is movably mounted within the plane perpendicular to the lock arrangement axis 67.

For this purpose it lies with one side on the facing end side of the driver part 25 and with the opposite side of the hinge rod end 59 (see Fig. 4a, 4b, 5a, 5b).

4c and 5c show the cooperation of bar 35 and driver part 25. In the release position of the bolt 35 according to FIG. 4c, the passage opening 37 of the bolt 35, as explained, aligned with respect to the block 15 and thus centered with respect to the lock arrangement axis 67. The Anlenkaussparung 39 engages around the fixing pin 43. The crescent-shaped cam portion 31 of the driver 25 is located with respect to the fixing pin 43 substantially opposite to the driver portion 71 of the bolt 35 at.

From this state, the latch 35 is moved to the locking position by the driver member 25 performs a rotation about the lock assembly axis 67, which extends in the clockwise direction with respect to the representation of FIG. 4c and 5c. The driver portion 31 of the driver 25 moves along along the driver portion 71 on the outer circumference of the bolt 35 and thereby forces the latch 35 to a locking movement in which the latch 35 pivots counterclockwise about one to the fixing pin 35 and the other from the fixing pin 43 radially away, so that the Anlenkaussparung 39 partially disengaged from the fixing pin 43.

5c shows the latching position of the bolt 35 achieved thereby. The passage opening 37 of the bolt 35 is now offset with respect to the lock arrangement axis 67 and thus with respect to the block 15. As a result, the latch 35 engages in a part of the locking recess 55 of the Klobens 15 one. Thus, the locking portion 41 of the bolt 35, which runs perpendicular to the lock arrangement axis 67, bears against the annular locking portion 57 of the bolt 15 (compare FIGS. 5a and 5b). The block 15 is thus secured against removal from the Klobenaufnahme 27.

The renewed release of the block 15 takes place in the reverse order, namely by the lock cylinder is actuated in the reverse direction of rotation and moves the latch 35 via the driver part 25 back into the release position shown in Fig. 4c.

A particular advantage of the illustrated locking of the clamp 15 within the clamp receptacle 27 is that in the locking position of the bolt 35 whose locking portion 41 flat with the locking portion 57 of the block 15 cooperates, as shown in Fig. 5a and 5b. As a result, tensile forces are transmitted uniformly - and not only at points or along contact lines - to the bolt 35 and thus to the lock body 11. Thus, the articulated bar lock shown has a particularly high tensile stability with respect to an attempt to forcibly remove the clamp 15 along the lock assembly axis 67 of the lock body 11. In such a tensile load of the bolt 35 and the cloche head 53 are only subjected to shearing, so that particularly high tensile forces needed to force a yielding of the bolt 35 or the cloche head 53 by force.

It is particularly advantageous that the flat locking portion 41 of the bolt 35 and the flat locking portion 57 of the block 15th each perpendicular to the lock assembly axis 67, so that the interaction of these locking portions 41, 57 is not the risk of slipping of the clamp on a locking slope.

By moving the latch 35 for transferring from the release position into the locking position within a plane perpendicular to the lock arrangement axis 67, the surface cooperation of the lock sections 41, 57 can be brought about without requiring any axial clearance along the lock arrangement axis 67 for the clamp 15 is that could simplify the attachment of a riser tool, for example between the mounting ring 45 of the block 15 and the ring receiver 69 of the lock body 11 and therefore undesirable.

Another particular advantage of the illustrated articulated bar lock consists in the manner of attachment of the joint rods 13a and 13c to the lock body 11 and the block 15. As soon as the block 15 is inserted into the lock body 11 and locked therein, embrace the ends 59, 47 both Joint rods 13a, 13c the Klobenhals 51. The joint rod end 47 of the joint rod 13c is namely, as explained, by means of the mounting ring 45 permanently attached to the clamp 15. The hinge rod end 59 of the hinge rod 13 a is attached to the lock body 11 in such a manner that the cock neck 51 penetrates the attachment hole 61 when the clamp 15 is inserted into the clamp receiver 27.

This double encompassing of the block 15 by the joint rods 13a, 13c has the advantage that in the case of an attack tensile load of the lock bars formed by the joint rods 13, 13b and 13c, this load is ultimately transferred mainly to the block 15 and the neck 51, respectively. As a result, excessive loading of the locking mechanism, in particular of the bolt 35 and the driver part 25 is avoided and prevents corresponding damage to the locking of the articulated bar lock.

The articulated bar lock shown in FIGS. 1 to 5 is designed such that the articulated rod 13a is fastened to the lock body 11 in the position shown in the figures by means of the fixing pin 43 for a service load in the normal operation of the lock. Only with excessive load on the hinge rod 13a, particularly in attempting to forcefully break or wind the lock bracket formed by the hinge rods 13a, 13b and 13c, the hinge rod 13a may move laterally due to slight bending of the fixing pin 43, so that the boundary surface of the attachment hole 61 comes to rest on the neck of the neck 51 and the further tensile load of the joint rod 13a is transmitted directly to the block 15.

It should also be noted with regard to the illustrated attack tensile load that this typically occurs when the lock strap formed by the joint rods 13a, 13b, 13c is swung open and guided around this object in order to secure an object. In such an attack tensile load, therefore, the lock does not have the collapsed configuration shown in Fig. 1, but the joint rods 13a, 13b, 13c are pivoted apart. This has the consequence that the joint rod 13 a and the joint rod 13 c attack during such an attack tensile load from opposite directions on the neck neck 51, so that it can absorb the load even more effective.

The transmission of such a Zugszugbelastung mainly on the block 15 is also supported by the fact that, as shown in particular in Fig. 4a, 4b, 5a, 5b, the joint rod 13a and the joint rod 13c the Klobenhals 51 each encompass within a plane perpendicular to the lock assembly axis 67 and thus extends to the longitudinal axis of the Klobenhalses 51.

1 to 5 is to be noted that the bolt 35 may also be composed of a plurality of disc-shaped locking elements, which have the same outline as the bolt 35 shown in the figures and arranged parallel to each other adjacent, in particular are attached to each other. In this way, a reinforced locking arrangement can be formed with an even higher shear stability, wherein the individual locking elements can still be manufactured as stampings according to a simple manufacturing process.

It should also be noted that in the lock shown preferably a positive lock is realized. This means that only by corresponding actuation of the lock cylinder by means of the associated identification means of the latch 35 is moved from the release position to the locking position and vice versa. Alternatively, however, an automatic function may be provided, in which the movement of the bolt 35 from the locking position to the release position by the lock cylinder associated with the identification means is triggered, the movement of the bolt 35 in the locked position, however - without the presence of the identification means - by introducing the clamp 15 can be brought into the Klobenaufnahme 27 against the bias by a spring.

Fig. 6 to 8 show a mortise lock, which corresponds to the articulated bar lock according to FIGS. 1 to 5 with regard to the construction of its locking mechanism. Similar components as in the illustrated articulated bar lock are marked with the same reference numerals.

In contrast to the articulated bar lock according to FIGS. 1 to 5, the mortise lock according to FIGS. 6 to 8 - for example as a brake disc lock - has a clamp 15 without hinge rods 13a, 13b, 13c and without any other lock bracket. The closure of the lock body 11 takes place at the end facing the clamp 15 by a radially inwardly directed constriction of the ring receptacle 69. At the end opposite the Klobenaufnahme 27 the lock body 11 is closed by a closing plate 73 which on the lock body 11 by a snap ring 75th is secured.

The locking of the clamp 15 within the clamp receiver 27 takes place, as explained in connection with FIGS. 1 to 5. Fig. 8a, 8b, 8c show the locking position of the bolt 35, corresponding to Fig. 5a, 5b, 5c.
