Definitions

  • the invention relates to a multi-point locking system for a door with an espagnolette lock with a bolt which can be actuated by a key, a latch and a drive rod with which a bolt of a locking swivel bracket lock can be actuated, the bolt being lockable by means of a handle arranged on the inside of the door of the locking swivel bracket lock is and can be closed by means of the drive rod.
  • the AT-PS 366 750 also shows a locking swivel bracket lock, which is driven by a drive rod.
  • the bolt of the locking swivel bracket lock is both forward and closed via the drive rod.
  • the invention is therefore based on the object, a multiple locking system of the type mentioned to train that when the espagnolette lock is opened, ie when the bolt is closed, the door remains secured by the bolt of the locking swivel lock.
  • This object is achieved in that a cam wheel driven by the drive rod is provided which engages in one direction of movement of the drive rod on the pre-locked bolt of the locking swivel lock and closes it back and performs an idle stroke in the other direction of movement of the drive rod.
  • the cam wheel of the locking swivel bracket lock is driven via the drive rod and the cam wheel leads one Idle stroke out, so that the bolt of the safety catch lock remains in its pre-closed position and secures the door.
  • the latch of the espagnolette lock is now locked from its position releasing the door, the espagnolette and the cam wheel of the locking swivel lock are actuated again. In this case, the cam wheel engages on the bolt of the locking swivel bracket lock and closes it back. In this case, the door is locked by the Espagnolette lock locked. If this is closed, the door is open.
  • the multi-point locking system has the significant advantage that when the door is unlocked and the bolt of the locking swivel bracket lock is locked, the door can be opened a little, but is held over the locking swivel bracket and therefore cannot be fully opened. A complete unlocking of the door by pressing the key once is therefore not possible.
  • the locking swivel shackle lock has a shackle which engages in the drive rod and is driven by it.
  • This bracket has the essential advantage that the drive rod for coupling the locking swivel bracket lock does not have to be interrupted or disconnected but only has to be prepared so that the bracket can be attached or hooked in.
  • the drive rod is provided with one or more recesses into which pins provided on the bracket can engage and the bolt of the locking swivel bracket lock can be locked past the drive rod. In this way, such a locking swivel bracket lock can be easily retrofitted without having to replace the drive rod.
  • the recesses for coupling the bracket and for the latch can be easily retrofitted.
  • the cam wheel preferably has two cams, the first cam engaging in the working path of the drive rod or the bracket and the second cam interacting with the bolt of the locking swivel bracket lock.
  • the first cam is driven by a sliding body, in particular by an extension of the drive rod or the bracket, i.e. postponed.
  • the second cam serves as a sliding body for the bolt.
  • the first cam is driven by the drive rod in a first pivoting direction, then the second cam bears against the bolt and moves it into its closed rest position. If the first cam is driven into the second swivel position by the drive rod, the second cam moves away from the bolt and carries out an idle stroke.
  • the cam wheel is preferably held in a rest position by a return spring. If the drive rod is moved from one end position to the other end position and takes the cam wheel with it over the first cam, then the first cam and the drive rod disengage before the drive rod reaches its other end position. The return spring then causes the cam wheel to be turned back and to assume its rest position. If the drive rod is actuated again, this time in the other direction, then the drive rod engages on the other side of the first cam and takes the cam wheel with it until shortly before the drive rod assumes its end position the first cam out of engagement with the Drive rod is coming. The cam wheel is then pivoted back into its rest position via the return spring. The return spring thus allows the cam wheel to be pivoted out of the rest position in both pivot directions.
  • the return spring preferably serves as a swivel limiter for the cam wheel.
  • a further development of the return spring provides that it acts on a nut for the handle and holds the nut in one or more defined rest positions. These rest positions correspond to the forward or closed position of the bolt of the locking swivel lock.
  • the width of the locking swivel lock corresponds to the width of the espagnolette lock.
  • the same milling tool can be used for milling the locking swivel bracket lock as for milling the espagnolette lock. Since the locking swivel shackle lock can be coupled to a conventional drive rod for additional bolts, there is no need for separate cutouts in the area of the faceplate. In particular, the drive rod rests on the back of the faceplate and / or is aligned symmetrically to it. Thus, the conventional milling tools can also be used for the milling of the drive rod or the faceplate.
  • the bolt of the locking swivel lock is preferably closed when the espagnolette lock closes.
  • the door remains locked via the espagnolette lock and is only unlocked by the subsequent subsequent unlocking of the espagnolette lock.
  • FIG. 1 An illustration of a drive rod lock driving a drive rod 1 has been dispensed with, since this can be designed as known from the prior art.
  • the espagnolette 1 extends upwards and possibly also downwards.
  • a locking swivel bracket lock 2 is attached to this drive rod 1 connected.
  • 1 to 3 show a first embodiment of such a locking swivel lock.
  • This has a housing 4 provided with stiffening ribs 3.
  • This housing 4 has a width b, which corresponds to the width of an espagnolette lock.
  • Fastening openings 5 are provided for fastening the housing 4 in a door, into which two screws can be screwed when the swivel-type lock is inserted.
  • the drive rod 1 is arranged symmetrically to the central plane 6 of the housing 4 and extends parallel to a faceplate 7.
  • the drive rod 1 can be continuous over the entire length of the locking swivel bracket lock 2 or, as shown, interrupted, the two ends of the drive rod being connected via a bracket 8.
  • This bracket 8 is essentially C-shaped and engages with its two free ends 9 and 10 in corresponding recesses 11 and 12 of the drive rod 1. In this way, the displacement movement can be transmitted from one drive rod 1 via the bracket 8 to the other drive rod 1, the bracket 8 being correspondingly displaced in the housing 4.
  • This bracket 8 is plate-shaped and engages over a bolt 13, which is shown in the drawing in the closed position.
  • This bolt 13 is provided in the region of its free end on the top and bottom with a groove 14 and 15, through which it can engage in a locked position in a locking bracket, not shown.
  • the bracket 8 is provided on its side facing away from the bolt 13 with a wart-shaped extension 16. If the drive rod 1 is moved from its one end position to its other end position, then the bracket 8 describes a displacement movement in which the extension 16 is displaced from its position shown in FIG. 1 to a position which is indicated by 16 '.
  • the cam wheel 18 has a second cam 20, which lies outside the working path of the extension 16 and engages over the bolt 13.
  • the bolt 13 has on its bolt extension 21 a pin 22 which is located in the closed position of the bolt 13 (as shown in the drawing) outside the pivoting range of the second cam 20. If the bolt 13 is closed, the pin 22 is in the position indicated by 22 '.
  • the second cam 20 shifts the pin 22 from the position indicated by 22 'to the right into the position shown.
  • the bolt 13 is closed in this way.
  • a first leg 24 of the return spring 23 is in a 24 'indicated position swung out. Since, when the cam wheel 18 is rotated, the first cam 17 pivots out of the working path of the extension 16, the cam wheel 18 is pivoted back into the rest position shown in the drawing under the force of the return spring 23 as soon as the extension 18 can slide past the first cam 17.
  • the extension 16 then assumes the position 16 'indicated in FIG. 1.
  • the bracket 5 If the bracket 5 is moved back, ie upwards, the pin 16 is moved from the position 16 'into the position shown in the drawing. It comes to rest on the underside of the first cam 17 and rotates the cam wheel 18 in the clockwise direction. As a result, the first leg 24 of the return spring 23 is deflected into the position indicated by 24 ". As soon as the extension 16 can slide past the first cam 17, the return force of the return spring 23 causes the cam wheel 18 to be returned to the position shown in FIG. The pivoting of the cam wheel 18 in the clockwise direction does not cause the bolt 13 to be displaced, irrespective of whether it is in the closed position shown in FIG. 1 or in the closed position not shown, since the second cam 20 is rotating of the cam wheel 18 is always removed from the pin 22.
  • the upward movement of the bracket 8 corresponds to the unlocking of the drive rod lock, ie Unlocking process. If the bolt 13 were thus locked, a door would still be secured via the bolt 13 engaging in the locking bracket even if the drive rod lock was
  • the bolt 13 is closed by means of a rotary handle, not shown, the axis of which is mounted in a square cross section 25 of a nut 26.
  • This nut 26 is formed over a part of its circumference as a pinion and engages in a section 27 of the bolt extension 21, which is designed as a rack 28.
  • a tooth 29 of the pinion of the nut 26 locks the bolt 13 against unintentional displacement by resting on an edge of a tooth 30 of the rack 28.
  • the nut 26 has on its underside a straight surface 31 on which the other leg 32 of the return spring 23 abuts. If the nut 26 is rotated counterclockwise to close the bolt 13, the leg 32 of the return spring 23 is pivoted into a position 32 ', as is indicated by a dash-dotted line. Since the nut 26 is held in a defined manner in the rest position shown in FIG. 1 by the leg 32 of the return spring 23, the bolt 13 cannot automatically shift into a pre-closed position but becomes in the closed position held, in which one end of an extension limiting the extension 33 of the bolt extension 21 abuts a pin 34.
  • FIGS. 4 and 5 show a second exemplary embodiment of a locking swivel shackle lock 2 of the multiple locking system according to the invention, the same elements having been given the same reference numerals.
  • the leg 24 of a return spring 23 acts on the cam wheel 18, the other leg 35 of which is supported on a stiffening rib 3 of the housing 4.
  • the leg 24 is bent at its free end and engages in an elongated hole 36 of the cam wheel 18, which has a substantially V-shaped recess 37 in which the cam wheel 18 has a smaller width.
  • the two walls 38 and 39 of the V-shaped recess 37 serve as a pivot limiter and are in the respectively pivoted-out position of the cam wheel 18 on the leg 24 of the return spring 23, the leg 24 assuming the position 24 'or 24' '.
  • the cranked end of the leg 24 moves in the elongated hole 36.
  • the stable rest position of the nut 26 is maintained by a spring 40 which is essentially U-shaped and has two legs 41 and 42.
  • the leg 42 is located on a stiffening rib 3 of the housing 4 and the leg 41 on the straight surface 31 of the nut 26.
  • the spring 40 can be designed as a leaf spring.
  • FIGS. 6 to 8 show a third exemplary embodiment of a locking swivel shackle lock 2 of the multi-point locking system according to the invention, the same elements having been given the same reference numerals.
  • the drive rod 1 is not continuous, but ends at the cam wheel 18. However, the use of a continuous drive rod is easily possible.
  • the free end 43 of the drive rod 1 bears against the cam 17 of the cam wheel 18, which is rotatably mounted about the axis 19.
  • the free end 43 of the drive rod 1 corresponds in function to the extension 16 of the bracket 8 according to the first two embodiments. If the drive rod 1 is moved in the direction of the arrow 44 (FIG.
  • the free end 43 drives the cam wheel 18 via the first cam 17 and rotates it in the clockwise direction about the axis 19.
  • the return spring 23, one of which is The end is fixed to a pin 45 of the housing 4 and the other end of which is fixed to a pin 46 lying in the rest position of the cam wheel 18 between the pin 45 and the axis 19 and projecting axially parallel to the axis 19 on the cam wheel 18, and this on the pin 46 fixed end unscrewed from the connecting line between pin 45 and axis 19. In this way, a restoring torque is generated in the rest position.
  • the bolt 13 is shown in its closed position, whereas in FIG. 7 the bolt 13 is pre-locked.
  • the bolt extension 21, which is bent is adjacent to the cam wheel 18 with an oblique side surface. If, as described above, the cam wheel 18 is rotated, then the second cam 20 presses on the oblique side surface 47 on the locking extension 21, which is described in more detail below.
  • a locking plate 48 is provided on the bolt extension 21, which is also provided with an elongated hole 36, in which the pin 34 engages.
  • the securing plate 48 has a second elongated hole 49, in which a pin 50 protruding from the locking extension 21 engages. In this way, the locking plate 48 is at least slightly displaceable in the forward direction of the bolt 13 with respect to the bolt extension 21, as can be seen from FIGS. 6 and 7.
  • the tooth 29 not only engages and displaces the toothed rack 28 of the bolt extension 21, but also a correspondingly shaped flank 51 of the securing plate 48 on the one hand together with the bolt extension 21 in the forward direction of the bolt 13 and relative to Bolt extension 21 or bolt 13.
  • the elongated hole 36 of the securing plate 48 is made slightly longer than the elongated hole 36 of the bolt extension 21.
  • the tooth 29 becomes the nut 26 via the flank 51 of the securing plate 48 behind the edge of the tooth of the rack 48 of the bolt extension 21 so far highlighted that the lock is released. If the securing plate 48 has been displaced by the second cam 20 by a small amount, then the second cam lies 20 additionally on the side surface 47 of the locking extension 21 and closes it back.
  • the nut 26 is provided on the side approximately opposite the tooth 29 with respect to the axis of rotation with a receiving opening into which a pin 53 of a holding arm 54 engages.
  • This holding arm 54 is adjustable in length and is pivotally mounted on a pin 55 fixed to the housing with its end opposite the pin 53.
  • the holding arm 54 is biased in the longitudinal direction by the spring 40 such that the pin 53 is always pushed away from pin 55 due to the spring force 40. In this way, the nut 26 is pushed into the rest position with the bolt 13 closed and held there, in which the tooth 29 abuts an edge of the tooth 30 of the rack 28 and thereby secures the rack 28 in the current position. In the pre-closed position of the bolt 13, the nut 26 is rotated, as shown in FIG.
  • the cam wheel 18, which is also equipped with two cams 17 and 20, is driven by the extension 16 of the drive rod 1.
  • the resting position of the Cam wheel 18, which is rotatable about the axis 19, is effected via the return spring 23, which is suspended on the pin 46 of the cam wheel 18 and on the pin 45 fixed to the housing.
  • this embodiment corresponds to that described above.
