Definitions

  • the invention relates to a locking device consisting of a bolt lock and key-operated locking cylinder according to the preamble of claim 1.
  • Such a locking device which is suitable for use on doors of lockers, is known from AT-PS 310 610.
  • the bolt lock is fixed on the inside of the door, while the locking cylinder passes through the door and can be actuated with a key which can be inserted from the outside of the door. If the bolt is in the closed position, the key cannot be removed. This can only be done after the pre-closing movement has been completed, which requires the insertion of a coin. If the user of a locker then loses the key, the locking device can be opened by means of a master key in the hands of a supervisor. However, if such a master key gets into unauthorized hands, appropriate lockers can be opened and closed again without leaving any traces.
  • the object of the invention is based on a locking device of the type in question simple to manufacture so that there is at least one key that allows opening, but the opening always leaves traces.
  • a locking device of the type in question of increased security value is created.
  • the locking device can be actuated in the usual manner by means of the normal key. If this key z. B. have been lost, the removal key can be used. After the same has been inserted into the key channel of the cylinder core, the latter can only be displaced, for example, by a limited partial rotation angle range. The bolt is not yet in its release position. However, turning the removal key around the limited angle of rotation section allows the locking cylinder to be removed. The locking device can then be opened. After removal, the lock cylinder can no longer be used with this removal key and the door can therefore no longer be locked. It is therefore necessary to install a new locking cylinder using a normal key.
  • such a configuration is provided that when the removal key is used, this releases the locking of the locking cylinder to its retaining bush after the limited rotation angle partial area has been covered. Only then is it possible to remove the locking cylinder.
  • One version is characterized by a finger which can be pivoted in front of the bolt actuation opening as a function of the bolt movement and blocks the latter. If the locking cylinder was removed using a removal key and the bolt was then closed using an auxiliary tool via the bolt actuation opening, then it is not possible to subsequently install the locking cylinder because its locking element finds the bolt actuation opening in the wrong position. If the bolt is pre-closed by means of the auxiliary tool, an aligned position of both can be achieved.
  • the pivotable finger then comes into action, which completely or partially blocks the bolt actuation opening.
  • a push-through opening arranged in the lock cover of a mortise lock and adapted to the locking member.
  • Such a removal key is to be used with which the locking member is in the position corresponding to the key insertion position is rotatable up to the aligned arrangement to the push-through opening.
  • the locking cylinder can thus be removed when the locking member is displaced by the removal key by the partial angle of rotation.
  • a push-through locking finger enters the area of the push-through opening and prevents the subsequent installation of the locking cylinder, which condition of the locking device is therefore an indication of the removal of the locking cylinder.
  • the push-through locking finger can only be brought into the unlocked position by using the correct key, which key then takes the place of the removal key.
  • Another option is to install a completely new locking cylinder with a normal key.
  • the push-through locking finger it is a simple component which can be incorporated inexpensively into the structure of a lock. When actuated by means of the normal key, the push-through locking finger is displaced against the spring load due to the leading flanks provided on it. It proves to be particularly cost-saving if the push-through locking finger is designed as a spring.
  • the locking device according to the first embodiment shown in FIGS. 1 to 16 has a bolt lock 2 fastened to the inside of a locker door 1 of a bathing establishment, the lock case of which has a lock base 3 and the lock case side walls 4, 5, 6 and 7 angled therefrom .
  • the upper lock case side wall 7 continues to form a hood which, on its one inclined side wall 8, contains a slide 9 with a calibrated coin slot 10.
  • the castle interior is covered by a castle ceiling 11.
  • the same is the carrier of a holding bushing 12.
  • Screws S which engage in the bottom region 13 of the holding bushing 12, are used to fix it in place from the inside of the lock cover 11.
  • the bottom region 13 is equipped with a bearing opening 15 which runs eccentrically to the sleeve wall 14 and through which the cylinder core 16 of a locking cylinder 18 mounted in the cylinder housing 17 passes.
  • Whose end surface is flush with the outer end wall of the holding sleeve 12 in the installed position.
  • the locking cylinder 18 in the retaining bush 12 receives a rotation and trigger lock by means of a catch 19.
  • a locking pin 20 which is guided in the secant-like orientation in the cylinder housing 17 and is cushioned in the outward direction, which is located at the inner end of the locking cylinder 18 and the protrudes with a region, not shown, in the cylinder core 16.
  • a normal key 21 illustrated in FIG. 8 and belonging to the locking cylinder 18 is not able to reach the locking pin 20 in its inserted position according to FIG. 7. This is only possible by means of a removal key 22 shown in FIG. 9, which has a longer key shaft than the key 21.
  • the key tip 23 of the inserted removal key 22 protrudes up to the catch 19.
  • the projection 27 of the cylinder core 16 protruding over the inner end of the locking cylinder 18 is equipped with a circumferential groove 28 on the inside of the lock case, to which a locking member 29 achieved by flattening on both sides is connected.
  • the key channel 30 of the cylinder core 16 continues into the locking member 29.
  • the latter engages in a cross-section-adapted recess 31 of a bolt driver 32.
  • the hub 33 contains on the inside of the lock case a radial slot 35 running transversely to the longitudinal axis of the lock cylinder. This is designed in the form of a partial annular groove which lies at the level of the circumferential groove 28. Resistant plastic is selected as the material for the bolt driver 32 plus hub 33.
  • the bolt driver 32 forms a control arm 36, which with a coupling pin 37 directed towards the lock is equipped. This engages in a transverse slot 38 of a bolt 39 guided in the bolt lock 2.
  • Its locking head 40 passes through a cross-section-adapted opening 41 of the lock case side wall 6 and interacts with a fixed frame-side locking plate, not shown, of the locker.
  • a slot 43 is provided in the bolt tail 42, which extends in the exclusion direction and is open at the edge and into which a square pin 44 on the bottom of the lock is inserted.
  • the bolt tail 42 is the carrier of a torsion spring 45 which loads the bolt 39 in the direction of the lock, that is to say in the opening direction.
  • a tumbler 47 designed as a one-armed lever is mounted around a lock pin 46 on the bottom of the lock base. The same is loaded by a spring 48 in the clockwise direction. From the broad side of the tumbler 47 facing the bolt tail 42, a locking finger 49 extends as far as the lock base 3 and penetrates a cutout 50 of the bolt tail 42 that runs in the form of a figure.
  • the recess 50 is equipped with locking edges 51, 52 running transversely to the closing direction of the bolt. When the bolt 39 is closed, the locking finger 49 is supported in the front region of the recess 50 on its lower edge, cf. Fig. 3.
  • a one-arm rocker 54 is supported around a bolt-tail pin 53 and is loaded by a leaf spring 55 in the clockwise direction.
  • a locking tail-side projection 56 on which the lower end of the rocker 54 is supported, serves to limit the swing of the rocker 54.
  • the latter is the carrier of a support pin 57, which passes through a recess 58 of the bolt tail 42 reaches and reaches to the castle floor 3.
  • the support pin 57 acts together with a bolt-side support shoulder 59. The distance between this and the support pin 57 is smaller than the diameter of a coin 60 inserted into the coin insertion slot 10, so that, as shown in Fig. 3, this only after it has been inserted by the support shoulder 59 and the support pin 57 is held.
  • a coin 60 can be inserted with the locker door open. Then the key 21 is also in the lock.
  • the closing rotation can now be carried out, with the control arm 36 of the bolt driver 32 carrying the bolt 39 in the exclusion direction.
  • the coin 60 is also taken along, which acts on the locking projection 49 with its edge and thus raises the tumbler 47 into such a position that the locking projection 49 does not interfere in the path of the locking edges 51, 52 of the bolt tail 42.
  • the bolt 39 can be fully locked into the position according to FIG. 4, from which the individual key 21 can be removed from the locking cylinder 18.
  • the rocker 54 abuts against a bend 11 'of the lock cover 11, pivots accordingly and releases the coin 60 to fall through, which is then held by a housing-side shoulder 61 and a support pin 62 of the bolt 39 in an intermediate position.
  • the coin 60 goes into a money return compartment 63, so that the bolt lock operates according to the deposit principle.
  • the lock cover 11 supports a pivot arm 65 in the area of the bolt head 40 of the closed bolt 39 around a pin 64, which arm forms a finger 66 pointing in the direction of the locking cylinder. This through engages the radial slot 35 of the hub 33 of the bolt driver 32 and dips into the circumferential groove 28.
  • the finger 66 is still supported on the connecting web 67 of the hub 33, which limits the immersion of the finger 66.
  • the upper end 68 of the swivel arm 65 is below the curved edge 69 of the tumbler 47.
  • the bolt lock can be actuated by means of an auxiliary key 70 according to FIGS. 10 'and 10'.
  • Its shaft 71 carries at its end a stepped guide extension 72, the cross section of which is adapted to that of the recess 31 of the bolt driver 32.
  • this auxiliary key 70 it is possible to lock the bolt 39 without inserting a coin. If the auxiliary key 70 is inserted when the bolt is closed, its narrow edge 71 acts upon the finger 66 during the pre-closing movement and lifts the finger 66 while at the same time taking the tumbler 47 in such a way that its locking projection 49 does not impair the closing of the bolt 39. In the pre-closed position, the finger falls into the position illustrated in FIG. 14 and thus extends in the area of the locking member push-through cross section.
  • closing the bolt 39 is also possible by means of the auxiliary key 70.
  • the corresponding narrow edge of the key shaft 71 acts on the finger 66.
  • the corresponding lock cylinders 18 are then to be installed in the holding bushes 12.
  • the user of a locker does not return the individual key 21 and the bolt 39 is pre-locked, it is possible to remove the locking cylinder 18 by means of the removal key 22, namely after turning the cylinder core 16 back by the limited angle of rotation area in which the catch 19 is canceled. If the locking cylinder 18 is now pulled out, the one run-on slope 73 of the locking member 29 acts on the finger 66 and lifts it up, which allows the cylinder 18 to be removed without interference. After pulling the same out, the torsion spring 45 comes into effect and moves the bolt 39 into its open position, along with a rotation of the bolt driver 32 as a result of coupling engagement between the latter and the bolt 39.
  • the locking cylinder 18 can no longer be inserted into the holding bush 12 by means of the removal key 22 , since the closing member 29 finds the recess 31 of the bolt driver 32 in an angularly rotated arrangement. A corresponding single key or a new locking cylinder must therefore be obtained.
  • the locker can be opened and closed again with an unauthorized remanufactured key 22 without leaving any traces. Opening is possible; then the lock cylinder 18 can no longer be used. E.g. then tries to pre-close the bolt by means of a screwdriver, the finger 66 falls into the cross-section of the locking member in the locking position of the bolt 39 and likewise prevents the locking cylinder from being inserted by means of the removal key.
  • the inventive concept can be extended to create a master key which is used both as a removal key and as an insertion key is cash and which can also include a main key function in terms of closure, taking into account a fine function. This means that in such a case the master key can be used to unlock and lock without inserting a coin and removing the deposit coin kept by the lock.
  • This master key could differ from the removal key in that it has a notch in its key shaft, which is elongated compared to the individual key, and which interacts with a rotation-limiting pin of the locking cylinder.
  • the master key could be designed so that it retracts the latch to insert the lock cylinder.
  • the locking device has a bolt lock 74, illustrated in sections, with bolt 91 guided therein.
  • the lock cover 75 of the bolt lock 74 carries a retaining bush 76, the inner contour of which is adapted to that of a profile locking cylinder 77 .
  • the locking cylinder 77 is designed as a half cylinder. It can be closed by means of a normal key 78 and a removal key 79, the shaft of which is longer than that of the key 78.
  • a latch 80 is also provided between the holding sleeve 76 and the locking cylinder 77, which can only be canceled by means of the longer-shaped removal key 79, in that the elongated tip 81 of the latch 80 removes the latch 80 after a rotation angle of less than 90 ° has been covered .
  • the removal key 79 forms stops which determine the angle of rotation of the cylinder limit core 83.
  • the normal key 78 of the cylinder core can be turned freely in both directions.
  • the lock member 82 of the lock cylinder 77 is located behind the lock cover 75, in a rotationally offset arrangement to a push-through opening 84 of the lock cover 75 running radially to the cylinder core 83.
  • the layout of the push-through opening 84 is somewhat larger than that of the lock member 82.
  • the push-through opening 84 also extends into the holding sleeve 76.
  • a spring-loaded push-through locking finger 85 protrudes into the push-through opening 84.
  • the same is designed as a spring and is clamped in a bracket 86 on the lock case side in such a way that the angled free end of the locking finger 85 projects into the push-through opening 84 and thus also lies in the turning circle of the locking member 82.
  • bevels 87 and 88 are provided on the locking finger 85. Accordingly, the locking finger 85 deflects resiliently during the closing rotation, in order then to pivot again into the forward position.
  • Removal of the locking cylinder 77 requires the removal key 79.
  • the locking member 82 can only be rotated by a small amount of angle, and only clockwise. This rotational movement is limited in which rotationally limited position the catch 80 between the lock cylinder 77 and the holding bush 76 is canceled. Then the locking member 82, which has shifted the locking finger 85 into the position shown in FIG. 23, is aligned with the push-through opening 84 of the lock ceiling 75. The lock cylinder 77 can thus be removed. As soon as the locking member 82 releases the locking finger 85, it moves into its locking position, so that it is no longer possible to insert the locking cylinder 77 again by means of the removal key 79. In the event of an attempted insertion, the closing member 82 pushes against the locking finger 85, so that the insertion movement is limited. An unauthorized attempt to open the door with a counterfeit key will leave traces because the burglar can no longer install the locking cylinder.
  • the bolt 75 can be pre-closed, the locking member 82 being immersed in the bolt actuation opening 89 or 90 of the bolt 91.
  • the pivoting of the locking member into the bolt actuation opening 89, 90, on the other hand, by means of the removal key 79 is not possible due to the stop angle range of rotation of the locking member.
  • the basic principle of the lock cylinder which can be removed but cannot be used with the same means, can also be used advantageously, for. B. in the delivery of locks.
  • Solutions of AT-PS 310 610 are the installation of the locks in the locker door so that the lock must be delivered together with the cylinder core. The installer of the lock must therefore either be given the individual key belonging to the respective lock or a higher-level key in order to check the locking function of the lock used. This does not exclude that keys can get into unauthorized hands, so that illegally manufactured duplicate keys give access to locked lockers in order to steal items stored there.
  • the object can additionally be achieved to optimize the lock of a generic locking device in terms of installation and security such that neither the individual key nor a superordinate key has to be handed over to the lock installer.
  • a lock of a locking device of the type in question is specified, which is characterized not only by advantages in terms of installation technology, but also by an increased security value.
  • the lock cylinder does not have to be fixed to the lock.
  • the lock is delivered in this pre-assembled state. So that the lock builder can still close the bolt during installation to check the functionality, he is trained instead of a single key or a superordinate master key only makes the connection to the bolt.
  • the corresponding locking cylinders are then used by a person of trust so that, on the one hand, the cylinder core engages in the coupling and, on the other hand, the cylinder housing comes into the plug connection.
  • One version is characterized by providing the cylinder core and the auxiliary key with a pinion at their free end.
  • the auxiliary key allows the bolt to be operated when installing the lock, which is equipped for this purpose by means of a toothed rack. If the locking cylinder is installed, the pinion of the cylinder core meshes with the toothed bar of the bolt.
  • Another possibility of coupling the cylinder core or the auxiliary key to the bolt is to provide a driver mounted in the lock for coupling / plug-in engagement with the cylinder core and for actuation with the auxiliary key.
  • the driver is no longer part of the cylinder core or sits on the end of the cylinder core, but the cylinder core can now be brought into the coupling / plug engagement to the driver, combined with the advantages mentioned above.
  • Different coupling / plug-in interventions can be implemented on this basis.
  • One embodiment is shown to store the driver in an opening in the castle ceiling.
  • the provision of the coupling connection between the driver and the cylinder core is facilitated by the measure that the driver consists of a disc mounted in the opening of the lock top.
  • One version consists of two discs connected in the direction of their axis of rotation share to form.
  • One disc part then directly engages the bolt with its control arm, while the other disc part, which is coupled in a rotationally connected manner to the one disc part, has the polygonal recess for clutch engagement with the cylinder core.
  • the disk part which otherwise faces the cylinder core, can then be brought into the correct position in which the locking cylinder can be inserted. If the orientation of this disk part differs from that of the cylinder core, the clutch engagement cannot be accomplished.
  • a position is preferably selected in which the locked position of the bolt is then present. This means that the key cannot be removed after inserting the locking cylinder in this position.
  • the corresponding coin In order to be able to lock this, the corresponding coin must be inserted as a control element, which then releases the locking function when the bolt is closed.
  • the disc In order to allow the bolt to be closed without a coin being inserted when the lock cylinder is not assigned, the disc has a breakthrough extending into the lock interior for a control projection of the auxiliary key. This can also be the construction key so that the functionality of the lock can be checked when the lock is mounted on the door.
  • the bracket protruding from the lock ceiling, into the cavity of which the lock cylinder can be inserted, is used to securely hold the lock cylinder to be subsequently installed. In the final phase of the insertion movement, a stop then comes into effect, which fixes the locking cylinder or its housing.
  • the locker can then be brought back into a locked position and can only be opened using the auxiliary key in the hands of the supervisory staff.
  • the transmission means which the auxiliary key shifts with its control projection when it is actuated, is the swivel arm that controls the guard locking in the release position. If the bolt is locked, the swivel arm has no influence on the guard locking.
  • the locking cylinder cannot be installed in this pre-closed position. This requires the locking of the bolt, in which process the control projection shifts the swivel arm, which in turn lifts the tumbler and holds it in the closed position of the bolt in the raised position.
  • the locking cylinder can be installed in this position because the clutch engagement between the cylinder core and the disc can be established.
  • the bolt can be closed without a coin being inserted due to the release position of the tumbler by the swivel arm.
  • the release of the guard locking basically requires the bolt to be closed.
  • the lifting position is secured by the frictional engagement of the swivel arm end on the lower edge of the tumbler.
  • the bondage is only released when the closing When the bolt is locked, the tumbler bumps against a corresponding bolt slope after the corresponding distance has been traveled. It is slightly raised, so that the swivel arm then returns to its original position.
  • the frictional engagement between the swivel arm and guard locking takes place in the area of the crescent nose thereof, the contact edges of the crescent nose and swivel arm end pivoting on intersecting arches, which require a deliberate release of the frictional engagement system.
  • the disc is designed as a hub equipped with a control arm, which has a polygonal recess for coupling with an extension of the cylinder core. Then the disc can be designed in one piece. It itself contains the recess for coupling with the extension of the cylinder core. In such a case, it proves to be advantageous if the extension of the cylinder core forms the opening, from which a partial annular groove emerges on the inside of the lock, into which the control projection of the auxiliary key projects. If the locking cylinder is not installed, the auxiliary key can take effect by applying its control projection to the corresponding flank of the swivel arm during its locking rotation.
  • the hub has a bearing collar which is connected to the control arm via an arch web.
  • the correct coupling can therefore always be generated, namely in the corresponding rotational position of the hub or disc.
  • the lock cylinder receives a sufficiently tight fit in that the carrier is designed as a sleeve, in the Floor area the pane is accessible. In the case of a two-part disk, this sleeve can also take on the function of storing the disk part to be coupled to the cylinder core. Then the sleeve can still be used to store the auxiliary key. However, this presupposes that the bearing opening for the corresponding disk part runs concentrically with the inner wall of the bush. In such a case, the width of the plate-shaped auxiliary key must be adapted to the inner diameter of the sleeve.
  • the lock according to the first embodiment, shown in FIGS. 1a to 16a, has a lock case 2a fastened to the inside of a locker door 1a of a bathing establishment, which has a lock bottom 3a and the lock case side walls 4a, 5a, 6a and 7a angled therefrom.
  • the upper lock case side wall 7a continues to form a hood, which on its one inclined side wall 8a contains a slide 9a with a calibrated coin slot 10a.
  • the lock set-up is covered by a lock cover 11a.
  • the same serves to hold a carrier designed as a sleeve 12a.
  • Screws (not shown), which are screwed in from the inside of the lock cover 11a and which engage in the bottom region 13a of the sleeve 12a, can be used to fix the sleeve 12a.
  • the bottom region 13a is equipped with a bearing opening 15a which runs eccentrically to the sleeve wall 14a and which is penetrated by the cylinder core 16a of a locking cylinder 18a which is mounted in the cylinder housing 17a and which is installed in the sleeve 12a and which, in the installed position, has its end face with the outer end wall Bushes 12a flush.

  • An individual key 21a illustrated in FIG. 8a and belonging to the locking cylinder 18a cannot reach the locking pin 20a in its inserted position according to FIG. 7a.
  • This is only possible by means of a special key 22a which is elongated compared to the individual key 21a, the key tip 23a of which protrudes in the inserted position up to the catch 19a.

  • the control arm 34a is a carrier of a coupling pin 40a directed towards the lock, which engages in a transverse slot 41a of a bolt 42a guided in the lock case 2a. Its locking head 43a passes through a cross-section-adapted opening 44a of the lock case side wall 6a and interacts with a striker plate, not shown, of the locker.
  • a slot 46a is provided in the bolt tail 45a, which extends in the exclusion direction and is open at the edge and into which a square pin 47a on the lock case side is inserted.
  • the bolt tail 45a is a carrier of a torsion spring 48a, which loads the bolt 42a in the direction of the lock.
  • a tumbler 50a designed as a one-armed lever, is mounted around a stay pin 49a on the lock case side. It is loaded clockwise by a leaf spring 51a. From the broad side of the tumbler 50a facing the bolt tail 45a a locking finger 52a extends to the inner surface of the lock bottom 3a, which has a figure-extending one Recess 53a of the bolt tail 45a penetrated. This recess 53a is equipped with locking edges 54a, 55a running transversely to the closing direction. The rear area of the recess 53a forms a locking bevel 56a, the effect of which will be described later. When the bolt 42a is closed, the locking finger 52a is supported in the front region of the recess 53a on the lower edge thereof, cf. Fig. 3a.
  • a one-armed rocker 58a is mounted around a bolt 57a on the bolt tail side and is loaded in the clockwise direction by a leaf spring 59a.
  • a locking tail-side projection 60a on which the lower end of the rocker 58a is supported, serves to limit the swing of the rocker.
  • the rocker arm is the carrier of a support pin 61a, which extends through a recess 62a of the bolt tail 45a and extends to the lock base 3a.
  • the support pin 61a interacts with a bolt-side support shoulder 63a.
  • the distance between this and the support pin 61a is smaller than the diameter of a coin 64a inserted into the coin insertion slot 10a, so that, as shown in FIG. 3a, it is only held by the support shoulder 63a and the support pin 61a after it has been inserted.
  • the coin 64a can be inserted because the locker door is in the open position. Then the individual key 21a is also in the lock. The closing rotation can now be carried out, with the control arm 34a of the hub 35a entraining the bolt 42a in the exclusion direction. Along with the pre-closing movement of the same, the coin 64a is also carried, which acts on the locking finger 52a with its marginal edge and thus the tumbler 50a into one Position raises that the locking finger is not disturbing in the path of the locking edges 54a, 55a of the locking tail 45a. As a result, the latch 42a can be fully locked into the position according to FIG. 2a, from which the individual key 21a can be removed from the locking cylinder 18a.
  • the rocker 58a abuts against a bend 11a 'of the lock cover 11a, pivots and releases the coin 64a to fall through, which is then held in an intermediate position by a shoulder 79a on the housing and a support pin 80a of the bolt 42a.
  • the latch 42a is closed, the coin 64a enters a money return compartment 81a.
  • the castle works on the deposit principle.
  • the lock cover 11a supports in its lower area facing the bolt head 43a around a pin 65a a swivel arm 66a which is guided in an arc around the control arm 34a such that the swivel arm end 67a lies below the end 68a of the tumbler 50a.
  • the lower edge of the end 68a is shaped into a crescent nose 69a.
  • the tumbler 50a has a recess 70a facing the lock cover 11a, which in turn lies in the plane of the swivel arm 66a or the swivel arm end 67a.
  • a contact edge 71a is formed by the recess 70a, which cooperates with the contact edge 72a of the swivel arm end 67a.
  • flank 73a which, when the locking cylinder 18a is inserted, dips into the circumferential groove 28a and is supported on the bottom thereof, cf. Fig. 5a. Then the contact edges 71a, 72a lie one above the other and are accordingly not in engagement. The entry of the flank 73a is possible through the partial annular groove 29a of the hub 35a.
  • auxiliary key 74a receives a plug-in limitation from transverse steps 79a lying at the same height.
  • the area 75a 'adjoining this in the direction of the coupling piece 76a' is adapted in its width to the diameter of the bearing opening 15a in the bottom area 13a of the sleeve 12a.
  • this auxiliary key 74a it is possible to lock the bolt without inserting a coin. If, when the bolt is closed, the auxiliary key 74a is inserted in the correct position, the flank 73a of the swivel arm 66a acts on the control projection 77a during the pre-closing movement. This action is possible through the partial ring groove 39a, into which the pivot arm dips with its flank 73a. When the auxiliary key 74a is closed, the bolt 42a is pre-locked.
  • control projection 77a pivots the swivel arm 66a counterclockwise. The latter raises the tumbler 50a with its swivel arm end 67a in such a way that the locking finger 52a does not impair the pre-closing. In the closed position, the finger 52a is then supported on the locking bevel 56a, as is also shown in FIG. 6a.
  • the locking bar 42a can also be closed by means of the auxiliary key 74a.
  • the control projection 77a acts on and displaces the flank 73a of the swivel arm 66a, the contact edges 71a and 72a of the tumbler 50a and swivel arm end 67a engaging.
  • This engagement remains even if the return rotation has been completed, i. that is, the latch is retracted.
  • An automatic release of the frictional connection between the contact edges does not occur, since the contact edges 71a, 72a pivot on bends B1 and B2 which cross each other, cf. in particular Fig. 15a.
  • This position is the one usually left by the lock builder.
  • the locking cylinder 18a can then be used in the manner described above, the extension 27a of the cylinder core 16a in coupling engagement with the driver or disk 33a mounted on the lock side and the locking cylinder 18a coming into the externally detachable plug connection.
  • This design also opens up the possibility, if the user of a locker does not return the key 21a, to remove the lock cylinder 18a, after closing the bolt 42a by means of the special key 22a, during which shifting of the coin 64a falls into the coin return compartment 81a. In the closed position, the lock cylinder 18a can be removed and replaced by another. However, if the compartment is to be closed again without inserting a coin, the auxiliary key can be used, by means of which the bolt can be locked and then closed again, so that the position according to FIG. 15a is obtained. Then the tumbler 50a, carried by the swivel arm 66a, is in a recess Order. The new locking cylinder is to be used in this. When the pre-closing movement then takes place, which can be carried out without coins, the engagement between the contact edges 71a, 72a of the tumbler 50a and the swivel arm 66a is canceled.
  • the locking of the bolt 42a presupposes the insertion of a coin.
  • the tool key 82a illustrated in FIG. 11a is used, which only forms a coupling piece 76a and has no control projection.
  • the tool key 82a is provided with cut-outs 82a ⁇ on the edge edge, to which the bearing area 82a ′ of the tool key 82a adjoins.
  • the locking cylinder bears the reference number 83a.
  • This is provided with a locking pin 84a which can be controlled by a special key.
  • Another spring-loaded pin 85a is adjacent to the latter and does not require any special control by the special key.
  • the pins 84a and 85a act together with corresponding holes 86a, 87a of a bush 88a to be fixed in a similar manner on the lock cover 11a.
  • a spherical adjustment projection 89a is also provided, for which the sleeve 88a forms a groove 90a which is open on the inside.
  • the sleeve 88a has a centering collar 91a which is form-fitting is received by a bore 92a of the castle ceiling 11a.
  • the driver moving the bolt likewise consists of a disk mounted in the opening of the lock cover 11a, which in turn is formed by two disk parts 93a, 94a which are connected in the direction of its axis of rotation.
  • the one disk part 93a continues into a control arm 95a which engages on the bolt 42a and has a coupling pin 96a.
  • the other disk part 94a is equipped with a polygonal recess 97a for clutch engagement with the facing end 98a 'of the cylinder core 98a.
  • This disk part 94a is supported in a stepped central bore 99a in the bottom area 100a of the bushing 88a.
  • the end 101a of the disk part 94a projecting over the base area engages in a form-fitting manner in a coupling recess 102a of the coupling part 93a.
  • the disk consisting of the two disk parts 93a, 94a has an opening 103a which extends in the extension of the key channel of the cylinder core 98a.
  • This opening 103a allows the use of an auxiliary key 104a illustrated in dash-dot lines in FIG. 18a, the control projection 105a of which projects into the opening 103a and dips into the circumferential groove 109a there and controls the swivel arm.
  • the insertion position of this auxiliary key 104a is limited by shoulders 106a, which are supported on the inside bottom surface of the sleeve 88a.
  • the control of the lock by means of the auxiliary key 104a corresponds to that of the embodiment described above.
  • auxiliary key 104a In order to be able to store the auxiliary key 104a well, it is designed as a plate whose width x is adapted to the inner diameter of the sleeve y.
  • the tool wrench 107a illustrated in FIG. 19a is equipped at its shaft end with a driver projection 108a, which only allows a coupling engagement to be made between the disk part 94a. A control of the swivel arm 66a cannot take place during the closing rotation.
  • Both embodiments can also allow the direct fine function without the detour via the auxiliary key. Then the special key representing a cylinder change key only has to be extended into the area of the circumferential groove 28a of the cylinder core 16a or circumferential groove 109a of the disk part 94a.
  • the extended special key can be limited to the fine function (without cylinder change function) if the back of the key is released in the bush in the area of the locking of the cylinder housing.
  • FIGS. 20a to 22a largely corresponds to that of the first embodiment.
  • the cylinder core 16a now carries at its free end a toothed pinion 110a, which is preceded by a circumferential groove 28a.
  • the flank 73a of the swivel arm 66a plunges into it and thus forms a support for the latter.
  • the key slot 111a projects into the pinion 110a.
  • the latter meshes with the teeth of a toothed strip 112a of the bolt 42a flanking a bolt opening. Provision is also made to ensure that the key is only available at locked bolt is removable from the lock cylinder. During the normal closing operation by means of the key, the bolt can only be piloted if the required coin 64a is entered into the lock.
  • the pinion 110a has a lifting bevel 113a for the swivel arm 66a at the end facing the circumferential groove 28a. If the bolt is in the closed position and the lock cylinder with cylinder core 16a is removed, the lifting bevel 113a acts on the swivel arm 66a in the region of the flank 73a and displaces it so far that the pinion gear 110a can pass through the swivel arm. Then the swivel arm 66a falls back due to gravity, which swivel movement is limited by a stop pin 121a of the lock cover 11a.
  • the insertion of the lock cylinder also requires a control slope 114a, which is located on the front of the pinion 110a.
  • the bevels 113a, 114a can either extend over the entire circumference or only over the corresponding angle of rotation, which allows the locking cylinder to be inserted or removed.
  • the auxiliary key 115a illustrated in FIG. 22a largely corresponds to the auxiliary key 74a.
  • the coupling piece is now a pinion 116a.
  • the latter like the toothed pinion 110a of the cylinder core for controlling the swivel arm 66a during the assembly or disassembly of the lock cylinder, is provided with corresponding bevels 117a, 118a.
  • a control projection 119a adjoins the toothed pinion 116a, which is opposite a recess 120a.
  • the auxiliary key 115a allows the bolt 42a to be locked without inserting a coin. With the corresponding closing rotation, the control projection 119a shifts the swivel arm 66a over its flank 73a. The operation of this auxiliary key 115a is equivalent to the auxiliary key 74a. Such a dimensional coordination between the pinion 116a and the control projection 119a is created such that when the auxiliary key 115a is removed, the swivel arm 66a does not leave the raised position of the tumbler 50a. The new locking cylinder can then be inserted, the control bevel 114a of the cylinder core not taking effect.
