Definitions

  • Conventional locking devices on apartment doors etc. today usually consist of a rectangular, flat lock case, usually made of metal, which is inserted into the front of the door leaf and screwed there by means of the metal cover protruding above and below the lock case.
  • a square recess extends through this lock case, generally in the upper area transversely to the door leaf, which receives a corresponding square, which is non-rotatably connected to the two door handles, and actuates the snap lock of the door.
  • the security lock cylinder which is standardized in its external dimensions, by locking and releasing the door latch from the front surface of the panel and thus out of the door leaf and into the corresponding recess in the Strike plate of the door frame can be moved into it.
  • the security effect of a door only consists in the locking bolt actuated by the security locking cylinder.
  • the security lock cylinder known from DE-A-2 622 816 is held in the lock case and thus in the door by a locking screw which is inserted in the door leaf level through the cover of the lock case, and in the lock case and through the lower area of the security locking cylinder extends across it.
  • a locking screw which is inserted in the door leaf level through the cover of the lock case, and in the lock case and through the lower area of the security locking cylinder extends across it.
  • the locking screw can be removed unnoticed, especially on heavily frequented doors during the normal course of the day, in which this door is likely to be open for a long period of time, so that the supposedly locked door can still be opened later by simply removing the security locking cylinder.
  • the security locking cylinder is to be secured against being pulled out by a bolt running through its transverse bore, but the possibility of pulling out this bolt is in turn definitely controllable in terms of accessibility.
  • a non-threaded locking bolt preferably made of hardened steel, is used, which is coupled in its front end facing the cover of the lock case to a lock.
  • a lock modified from the commercially available plug lock is preferably used for this purpose, at the rear end of which the securing bolt is firmly connected by means of brazing or a cross pin.
  • the mortise lock which has the well-known keyhole-shaped outer contour, is not used to ensure the locking function directly in the lock case, but in a correspondingly designed locking block, which is either inserted subsequently into the lock case or during the new creation, u. U. also in one piece, can be formed together with this.
  • This locking block has a through opening parallel to the door leaf level, that is to say transversely to the longitudinal direction of the security locking cylinder, which in the assembled state of the locking block and of the security locking cylinder in the lock case with the cross hole of the security lock cylinder.
  • the locking block sits in the lock case so that one of its sides lies in the plane of the cover of the lock case or is parallel to it and accessible from the outside through a corresponding opening in the cover.
  • the securing bolt striving at the rear end of the mortise lock extends through the corresponding transverse bore in the security locking cylinder, thereby securing it.
  • part of the narrow, beard-shaped extension can generally be pivoted by 90 ° with respect to the rest of the plug lock. In this pivoted, locked position, the key of the plug lock can be removed.
  • the locking block therefore has, in the course of its continuous opening, an enlarged recess which allows the movable beard part of the plug lock to pivot and then prevents the plug lock from being pulled out by the turned part of the beard resting against one of the end faces of the enlarged recess.
  • the key in the plug lock can be turned and removed, so that the plug lock can only be removed by destruction.
  • the transition between the securing bolt which as a rule has a smaller outer diameter than the rounded, thicker part of the plug lock and the plug lock itself, is a widened collar which runs around the securing bolt and which coincides with this in one piece and therefore usually consists of hardened steel.
  • This collar has an outer diameter which corresponds as closely as possible to the inner diameter of the through bore in the locking block, so that this collar must be guided exactly through the bore of the locking block in order to pull out the securing bolt.
  • the plug lock which is generally made of soft metal, is destroyed, and u. U. Even if the collar is drilled in further, it is completely or partially separated from the rest of the securing bolt. However, the chips generated during drilling usually result in jamming if the securing bolt accessible in this way is to be pulled out using mechanical means or a magnet. Even a very small chip is sufficient to no longer be able to insert the collar into the through opening of the locking block, which completely prevents the safety bolt from being removed.
  • a spiral spring is also pushed over the shaft of the security bolt, which presses the security lock cylinder against the corresponding wall of the lock case and retracts with it when the security pin and thus plug lock is inserted supports the other end either on the collar of the securing bolt or a corresponding end face of the plug lock or the locking block.
  • the corresponding opening is most easily created by removing the front panel from the lock case and replacing it with a new front panel equipped with the corresponding front opening.
  • Fig. 1 the door leaf 16 can be seen in a cut view, with the fold 17 of the door.
  • the lock case 2 is inserted into a corresponding recess in the door leaf 16 from the narrow side of the door leaf, that is to say the fold 17.
  • the rotatable socket with the inner square 18 can be seen, through which the corresponding, continuous profile bar, which is connected to the door handles on both sides, passes.
  • the security lock cylinder 1 In the lower area of the lock case 2, the security lock cylinder 1 is shown, which fits into a corresponding recess in the lock case 2 and is inserted into the lock case 2 with its longitudinal axis transversely to the plane of the lock case 2, i.e. parallel to the axis of rotation of the square 18.
  • the security lock cylinder 1 has in its lower, beard-shaped area a through hole 3 transverse to the longitudinal axis of the security lock cylinder 1 and thus in the plane of the lock case 2, through which a locking screw 4 extending from the front side of the door 16 extends through the panel 15 and the lock case 2 and the through hole 3 of the security lock cylinder 1 extends through it.
  • this securing screw 4 can only be seen from the front, only when the door 16 is open screwed in or unscrewed. Only after removing this locking screw 4 is it possible to remove the security locking cylinder 1 from the lock case 2 and thus the door leaf 16.
  • FIG. 2 shows a similar, somewhat enlarged representation of the lower region of the lock case 2.
  • a locking block 5 is inserted between the two cover plates of the lock case 2 from below and via fixed connections 19 to the cover plates of the lock case 2 connected.
  • the fold-side end face of the locking block 5 is partially visible and accessible through a corresponding opening 20 in the panel 15 of the lock case 2, namely in the region of the fold-side mouth of a through opening 6 through the locking block 5, which with the through opening 3 of the security lock cylinder 1 is aligned.
  • the rabbet-side end face of the locking block 5 has a square projection 21 which fits into the corresponding opening 20 of the panel 15 of the lock case 2 and closes flush with this in the outer surface of the door leaf 16.
  • FIG. 6 shows a view in the direction of the door leaf 16 toward the panel 15.
  • the locking block 5 can be connected to the lock case 2 by further connections 19 in the plane of the lock case 2, by screwing or riveting from the cover 15, above and below the projection 21, as also shown in FIG. 6.
  • the protrusion 21 protrudes through an opening 20 of the cover 15, which is substantially smaller than the entire face-side face of the locking block 5 shown in broken lines, so that it cannot be pulled out of the lock case through the cover.
  • the through opening 6 has in its front, fold-side area a keyhole shape 8 in such a size that a key lock 10 can be inserted into this keyhole shape 8 of the through opening 6.
  • a widening 7 of the opening 6 extends as an incision from the underside of the locking block 5 to beyond the upper edge of the through opening 6.
  • This widening 7 is arranged at such a point that when a plug-in lock is inserted into the key-shaped region 8 of the opening 6 and ends flush with the outer surface on the fold side, its rotatable part 11 of the beard is located in the region of the widening 7 and can thus be rotated .
  • Fig. 3 shows a lock case 2 equipped with a locking block 5 with security lock cylinder 1, in which a plug lock 10 is inserted with a locking pin 12 attached.
  • the mortise lock 10 ends flat on the fold side or set back somewhat in the fold-side outer surface of the panel 15 of the lock case 2.
  • a locking pin 12 At the rear, front end of the plug lock 10, which is usually made of brass or another soft metal alloy, a locking pin 12 striving on the longitudinal axis of the plug lock 10, made of hardened steel, is firmly connected to the plug lock 10.
  • the locking pin 12 is so long that it extends through the through hole 3 of the locking lock cylinder 1.
  • the mortise lock 10 By turning the rotatable part 11 of the beard of the mortise lock 10 by means of the key 23 of the mortise lock 10, the mortise lock 10 can be fixed in the locking block 5 and the key 23 can be removed. As a result, the locking pin can only be removed by those who have the key 23 for the plug lock and the door leaf 16 has opened, so usually has the key to the security lock cylinder 1, since the accessibility for the mortise lock 10 is only possible from the front side of the door leaf 16.
  • Fig. 4 shows an enlarged view of the lock 10 with the locking pin 12.
  • the lock 10 consists of the rotatable part 11, which also includes a part of the beard striving downward, and that facing the keyhole opening for the key 23 , fixed part of the plug lock.
  • the securing pin 12 is inserted sufficiently far and fastened by means of cross bolts or brazing, so that the securing pin 12 is connected to the mortise lock 10 in a tensile manner.
  • the locking pin 12 has a conical taper at its end facing away from the plug lock 10 and, over the central region, a diameter which is slightly smaller than the outer diameter of the round part of the plug lock 10.
  • the locking pin 12 In its end area facing the plug lock 10, the locking pin 12 is equipped with a circumferential collar 13 which, on the one hand, is used for bearing against the end face of the plug lock 10 when the locking pin 12 is inserted into the plug lock 10 and, on the other hand, to support one on the shaft of the locking pin 12 from the free end of the spiral spring 14.
  • the spring 14 which has a larger diameter than the through hole 3 of the Security lock cylinder 1, against this lock cylinder 1, and thus against the closest contact surfaces of the lock case 2, so that it is held firmly and rattle-free in the lock case 2.
  • This collar 13 thus serves not only for improved functional reliability, but also for easier assembly when assembling the locking pin with the plug lock 10.
  • circumferential collar 13 which is also made of hardened steel, acts as a drill protection.
  • the locking block 5 is again shown separately in perspective. Both the bores for the connection 19 between the sheets of the lock case 2 resting on the locking block 5 on both sides to recognize, as well as the continuous opening 6, which passes from the outer surface 9 of the projection 21 on the folded side to the opposite narrow side of the locking block 5.
  • the widening 7, which extends as an incision from the underside of the locking block 5 to the upper edge of the through opening 6, is still in the region of the keyhole shape 8, the through opening 6, which only ends somewhat within the widening 7.
