Definitions

  • the invention relates to a device on a door lock, the bolt of which is closed when the cylinder core of a locking cylinder is actuated with the aid of the locking lug of the cylinder, and with at least one additional bolt which locks the door leaf at a distance from the door lock and which is locked when the cylinder core is actuated a drive rod is closed with the aid of a gearbox acted upon by the cylinder core, which is housed in a housing of the door leaf.
  • Such a device is known from DE-A-29 29 368.
  • the gearbox is housed in the lock case, which is located in the door leaf.
  • the gearbox acts on a swivel lever, which in turn adjusts a drive rod present within the lock box upwards or downwards and at the same time causes the bolt to be closed or closed.
  • the drive rod has protruding rod sections protruding from the lock case, which carry locking pins at a distance from the door lock, with which the door leaf can be locked in place.
  • the known device has the disadvantage that it must be accommodated within the lock case. With regard to its structural design, it is limited to the volumes present in the lock case, which limits the design options, especially since the usual lock set-up must still be accommodated in the lock case.
  • the invention has for its object to improve a device with the features mentioned so that there are freedoms for the structural design, in particular in the area of arrangement and design of the components for driving the additional bolt or several additional bolts, in particular with regard to one increased security against destruction and improved stability.
  • the housing of the transmission for the additional bolt is arranged at the location of an inner door plate, and that the locking cylinder passes through the housing approximately to its visible side and, in addition to the locking lug, has a further locking element which acts on the outside of the door leaf Gearbox serves.
  • the housing of the transmission for the additional bolt is arranged on the inside of the wing, namely instead of an inside door plate.
  • the housing can be designed to be voluminous to the constructional requirements without being noticed as a nuisance.
  • the device can then also be retrofitted, that is to say attached to door leaves, without the existing lock having to be replaced.
  • the only exception to this is the locking cylinder.
  • This is designed according to the invention so that it penetrates the housing and of course the door leaf in the rest so that it ends approximately with the visible side of the housing.
  • the locking cylinder has another locking element that acts outside the door leaf to actuate the gearbox.
  • the locking lug with the drive of the additional bolt not concerned and all additional components for driving the additional bolt can be arranged outside the lock case area.
  • the arrangement of the device on the inside of the door also means an increase against unauthorized access, since it is protected in accordance with the overall door leaf thickness or in accordance with the construction of the door leaf. In principle, it is also readily possible to design the housing in such a way that unauthorized intervention in the transmission is made very difficult.
  • a configuration such that the housing has the longitudinal extent of an outer long plate and is screwed to it by means of inner screws serves to further improve the device with regard to avoiding a malfunction or destruction.
  • the adaptation of the longitudinal extent of the housing to that of an outer long plate enables the use of conventional connection techniques for this outer long plate and the housing for the burglar-proof connection of both parts through the door leaf.
  • hardened screws that cannot be removed are used, which make external and internal manipulations considerably more difficult.
  • a further advantageous embodiment of the device results from the fact that the housing in the area of the locking cylinder has a depth that allows the arrangement of pin tumblers of the locking cylinder on the front side of the further locking element. This not only guarantees the use of conventional keys for actuating the locking cylinder on the inside, but also the additional locking element is located in an area between the pin tumblers, i.e. in the case of a burglar-proof locking cylinder in a protected area, which gives unauthorized access to the drive parts of the device difficult for the additional bolt. At the same time, the housing also protects the locking cylinder on the inside of the door.
  • Such internal protection of the housing against opening is achieved in a special way in that the housing has a protective ring surrounding the inner end of the locking cylinder and if necessary is designed to be break-in-proof.
  • the break-in security of the housing itself which is to be set up as required, also protects against external opening, namely against opening through the door leaf.
  • the device is advantageously designed such that the housing essentially consists of two parallel, long shield-shaped housing walls, the spacing of which is coordinated with the dimensioning of the gear.
  • the housing With the help of the two housing walls, a flat and stable housing can be formed, the volume of which is limited to a minimum. This minimum is determined by the required dimensioning of the gear, that is by the thickness of any gears and / or levers or by the required design effort for bearing interventions of gear wheels.
  • a device can be further developed in that the gear is a reduction gear consisting of several gears, the wheel axles of which are mounted in the housing walls and / or in internal projections thereof.
  • the storage of the wheel axles in the housing walls enables a compact design, but this is due to perforations in the housing wall concerned.
  • inner projections can be formed on the housing wall, with which the wheel axles or pivotable levers can be mounted if the transmission does not consist of gear wheels, but of levers.
  • a drive wheel of the gear as concentric with the cylinder core of the lock cylinder is rotatable Gear part is formed. Rotations of the cylinder core lead due to its torsion-resistant connection to the gear part to corresponding twisting movements of the latter, which are correspondingly transmitted to the transmission, which adjusts the drive rod for the additional bolt accordingly.
  • the gear part can be a gear provided with teeth all around, but also a gear part which is only provided with a toothing on a partial circumference, if it is otherwise ensured that there is a permanent drive connection between the lock cylinder and the drive rod.
  • the device can be designed in such a way that the drive wheel is non-rotatably connected to the locking lug of the cylinder. A rigid connection is thus created between the gear part and the locking lug, which enables a 1: 1 transmission of the twisting forces acting on the cylinder core.
  • a torsion-proof connection of the drive wheel to the locking lug can be achieved in that a sleeve is connected at one end of its outer circumference to the locking lug and at the other end of its outer circumference to the gearwheel part, so that there is space for transmission elements in its interior for the functional connection of the cylinder core halves of a double cylinder.
  • the sleeve has the advantage that further necessary components of the locking cylinder can be arranged in its interior, in particular transmission elements for the functional connection of the cylinder core halves of a double cylinder, namely when a closing movement of the thumb is to be achieved from the inside of the wing or when a from the outside of the wing It should not be possible to turn the cylinder core if there is a key inside.
  • the device can be further developed such that the drive rod is guided in a guide housing of the housing and on the wing corner side and / or on the wing edge side in a wing-fixed guide housing.
  • Guidance is particularly necessary, namely in the area of the housing for the gear, where the gear function must be ensured, and in the area of a wing corner, where a wing-proof guide housing ensures that the drive rod has the required exact positioning.
  • the device can be designed such that the additional bolt is provided on the bolt side with a locking bolt which is guided longitudinally in a bolt guide piece of the guide housing.
  • the locking bolt and the bolt guide piece can each be designed so that a high level of security and precision results.
  • the drive rod only needs to be dimensioned in such a way that it is able to transmit the necessary adjusting forces and is itself sufficiently rigid.
  • the particularly enlarged cross sections of the locking bolt and, if necessary, of the bolt guide piece serve to be able to absorb larger shear forces which occur when the door leaf is loaded when the door is broken open.
  • the locking bolt is enlarged in cross section parallel to the wing plane.
  • the device can also be designed in such a way that the locking bolt can be closed at an angle to the direction of adjustment of the drive rod, which acts on the locking bolt with a corner deflection which has its driving force on the locking bolt.
  • the arrangement of the locking bolt at an angle to the drive rod offers the possibility of interlocking the additional bolt where it is most appropriate. If, for example, an intervention in the floor is not possible, a wall-side locking can be achieved by means of a corner deflection of the drive rod, which, with a corresponding structural design, is just as effective as a floor locking.
  • a particularly high level of security results from the fact that in the wing corner region two locking bolts which can be adjusted in different directions can be driven by a drive rod. There is then double intervention at different points, which secures the door wing corner particularly. Such double intervention is advisable, for example, if the additional bolt is made of e.g. should be kept particularly thin for optical reasons or if very high burglar resistance is to be aimed for. Double intervention can also be used to lock an additional wing.
  • FIGS. 1 to 5 all show an interior view of a door leaf 18 with devices according to the invention, which engage with locking bolts 39 in the frame 41 of a wall 42.
  • the engagement of the locking bolts 39 does not take place directly in recesses in the frame, as could be assumed on the basis of FIGS. 1 to 5, but there are locking pockets 43 which are embedded in the frame and are fastened there in a suitable manner.
  • Such closing pockets are also in a suitable configuration in the floor if the door wing 18 is to be locked on the floor.
  • the locking bolts 39 are driven from the device present in the area of the door handle 44, namely with a locking cylinder 13 which is turned by means of a key.
  • the rotation of the lock cylinder 13 is transmitted to a reduction gear 15, which drives one or more drive rods 19.
  • the drive rods then move the locking bolts 39.
  • 1 to 5 show that door leaves can be secured in very different ways by a device.
  • 1 shows a securing of the door leaf 18 on the leaf opening side on the upper frame spar and on the vertical frame spar below.
  • security is represented by a horizontal additional bolt in the middle area of the opening-side frame spar and in the middle area of the hinge-side frame spar, the hinges for the door wing not being shown.
  • 2 shows a simplified embodiment of the device with additional locking of the door leaf 18 on the opening side on the upper frame and on the opening side in the floor 45. If locking cannot be carried out there because the floor cannot be provided with a closing pocket 43 or should remain smooth, an additional locking is carried out on the wing opening side in the lower part of the vertical frame spar near the floor 45.
  • Figure 4 shows a locking of the door leaf 19 exclusively on the sash opening side frame up and down.
  • 5 shows the locking of a double door leaf 18, wherein the main leaf has additional bolts 14 which act vertically on the main leaf opening side with locking bolts vertically including the top of the window frame spar and the bottom 45 in the floor 45, but at the same time also horizontally exclusive locking bolts 39 which engage in locking pockets of the additional leaf 18 ' , which is also pivotable with hinges that have been designated 46.
  • FIGS. 6, 7, which is fastened on the inside of the door leaf opening side on the door leaf 18, serves to drive the locking bolts 39.
  • a lock 10 is arranged in a conventional manner, which has been shown schematically. It is equally spaced between the outer door surface 48 and the inner door surface 49.
  • the bolt not shown here and also in FIG. 6, is acted upon directly by the locking lug 17 of the locking cylinder 13 when the key can turn the cylinder core 12 if the pin tumblers 23, which are only indicated schematically, allow the cylinder core 12 to be rotated.
  • the locking cylinder 13 is aligned with its outer end face 50 with the outside of an outer long plate 52 to which a knob 53 is attached.
  • the knob 53 can be firmly connected to the lever handle 44 via a square 54.
  • the square 54 is mounted in a manner not shown in the outer long plate 52 and in the housing 16 so that it can pivot to a limited extent in order to drive the latch 10, which is not shown.
  • the inner end face 51 of the locking cylinder 13 projects beyond the outer surface 16 ′ of the housing 16, which is why it has a protective ring 25 which covers the projection of the locking cylinder 13.
  • the pin tumblers 23 of the inner part of the locking cylinder 13 designed as a double cylinder are arranged.
  • a further closing element 21, which is designed as a drive wheel 33, is arranged between these pin tumblers 23 and the locking lug 17.
  • This drive wheel 33 can be driven by the lock cylinder 13 and in turn acts on a reduction gear 15, which consists of a plurality of intermeshing gear wheels 28.
  • the driven wheel is referred to as driven wheel 31 and engages with its teeth in the toothing of a rack 32, which it adjusts vertically upwards or downwards according to FIG. 6 and according to its direction of rotation.
  • Such adjustment movements of the toothed racks 32 are transmitted via drive pieces 57 connected thereto to drive rods 19 which, according to FIG. 7, are guided by guide bushes 37 of the housing 16.
  • the required relative movement of the drive rods 19 with respect to connecting bushes 58 between the housing walls 26, 27 of the housing 16 are ensured by corresponding elongated holes 59.
  • the housing walls 26, 27 serve to support the gear wheels 28 of the transmission 15.
  • Axes 29 are present, each of which engages with one end in holes in the inner housing wall 26, while the outer housing wall 27 has inner projections 30, in the blind bores of which the ends of axles 29 engage, each of which has an annular collar 61 to hold the gears 28 in place and in engagement with each other and with the racks 32.
  • the locking cylinder 13 is designed in a special way, as was shown in FIG. It has already been mentioned that the drive wheel 33 is arranged between the two groups of pin tumblers 23 of the locking cylinder 13 designed as a double cylinder, as is the locking lug 17. Both have the same axis of rotation, namely the axis of rotation 62 of the cylinder core 12.
  • the driving wheel 33 and the locking lug 17 are connected to one another by a sleeve 35 which has the groove 63 shown on the outer circumference side and is connected to the locking lug 17 and at the same time also to the drive wheel 33 in a rotationally locking manner.
  • Each movement transmitted from the cylinder core 12 to the locking lug 17 therefore also causes a corresponding pivoting or rotating movement of the drive wheel 33.
  • the interior 36 of the sleeve offers space for transmission elements which connect the two halves of the cylinder core 12 to one another.
  • schematic coupling pieces 64 are shown, which bring about the required twisting coupling, in which they engage with connecting pins 65 in the interior 36 of the sleeve 35, for example, each being pressed together with the sleeve 35.
  • the locking device of an additional locking bolt 14 shown in FIGS. 9 to 11 is arranged on the leaf opening side at the bottom near the bottom edge of the door leaf.
  • the guide housing 38 serves to guide a locking bolt 39 and is provided with a bolt guide piece 40 for this purpose.
  • the locking pin 39 is rigidly coupled to a drive rod 19 by means of a guide slide 67 so that it carries out any longitudinal movement which is initiated by the drive rod 19.
  • the guide slide 67 is cranked according to Fig.10, so that the drive rods 19 and the locking bolt 39 are arranged coaxially.
  • the drive rod 19 is provided outside of the guide housing 38 with a cover cap 68 fastened thereon and to the housing 16, which in turn has a rod guide part 69 with a bore in which the drive rod 19 is guided.
  • a closing pocket 43 is arranged, which receives the bolt 39 which is closed by the drive rod 19. In this case, the door leaf 18 cannot be opened.
  • the cross section of the locking bolt 39 is dimensioned correspondingly large.
  • the cross section of the locking bolt 39 can be selected to be comparatively large, as shown in FIG. 12 in the drawing, namely trapezoidal.
  • the cross section of the locking bolt 39 is enlarged parallel to the wing plane and ensures a correspondingly greater opening resistance in the attempt to break open.
  • the relative section modulus can also be in the case of an additional bolt 14 according to FIG. 9 to 11 are enlarged, for example by choosing an oval configuration of the cross section of the locking bolt 39 according to the drawing in FIG. The enlargement of the cross-section parallel to the sash plane enables the locking bolt to be flatter than the round one, given the same section modulus.
  • the locking pin 39 can also be used when arranged at an angle to the drive rod 19, for example in order to avoid inclusion in the floor 45 according to FIG. 13, 14 show such a configuration using a corner deflection 70, in which the drive rod 19 and the locking bolt 39 are connected to a flexible deflection element 71 which is fixed at one end to the drive rod 19 and the locking bolt at its other end 39 advances and withdraws.
  • a wire rope is provided as a flexible deflection element 71, which is deflected by guide pins 72 and by a concave guide curve located in the guide housing 38, so that a vertical movement of the drive rod 19 results in a horizontal movement of the locking bolt 39.
