Definitions

  • the invention relates to an actuating device for a bolt of a lock provided with a receptacle for a lock cylinder, which can be actuated by the latter, of a window, a door and the like.
  • the lock should be a known type, in the receptacle of which a lock cylinder of conventional design can be used, the cross-section of the receptacle and lock cylinder housing agree.
  • Lock cylinders of this type are equipped with a rotary member, which can be rotated in its housing by at least 360 ° and has a lock bit, and can be driven by means of a key. A precisely defined stroke of the lock bolt is assigned to a key turn.
  • the lock bit is located in the assembly position within the cross-sectional contour of the housing, while it is radial over this contour after a certain angle of rotation and in particular in the working position coupled with the bolt of the lock protrudes.
  • Locks and, above all, locks built into a door are now almost completely equipped with locking cylinders of different cross-sectional shapes, especially for external doors.
  • profile cylinders which have a keyhole-like housing cross section, have prevailed.
  • Round cylinders are also known. In some other countries, they are the preferred cylindrical shape.
  • the lock cylinder can be replaced without having to remove the lock itself from the door, window or the like. The removal of a locking cylinder is particularly useful for security reasons if the key is lost.
  • Internal apartment doors i.e. doors that close the passage from one room to the next, are often equipped with so-called colored locks. The latter are relatively easy to overcome for a burglar.
  • knob cylinder which allows locking with the help of a knob or rotary knob on one side of the door.
  • Knauf cylinders of this type are, however, relatively expensive and they cannot be used in connection with inexpensive handle sets for bathrooms or the like.
  • the object of the invention is to provide an actuating device for a bolt of a lock provided with a receptacle for a lock cylinder of the type described above, which avoids the use of a special lock and which can be installed instead of a lock cylinder fitting in this lock and, if necessary, by a lock cylinder can be replaced or vice versa and which should also be as inexpensive to manufacture.
  • the installation of this actuating device should not be more difficult than that of the lock cylinder fitting in this lock.
  • This object is achieved according to the invention in an actuating device according to the preamble of claim 1 by the characterizing features of this claim.
  • This actuating device fulfills the demands placed on it, ie it can be installed at any time in a lock prepared for the installation of a lock cylinder and removed therefrom. So you can, for example, in the construction phase in such doors install, which is usually basically provided with a locking cylinder, in particular in external doors. You can equip this actuator with a relatively simple actuator that is cheaper to manufacture than a lock cylinder key, which actuator can even be left on the actuator during the construction phase. This means that anyone on the construction site or someone else who is authorized can open this door without a key. This actuating device can be exchanged for a locking cylinder at a later time.
  • this actuator is also suitable, for example, in the case of a bathroom that should only be lockable on one side, whereby again you can do without a key and instead use a simple handle that also aesthetically matches the handle set otherwise used on this door .
  • the lock bit To insert the actuating device into the receptacle of the lock, like in the case of a lock cylinder, its lock bit must assume a rotational position in which it does not protrude laterally beyond the cross-sectional contour. This assignment of the locking bar to the housing is referred to as the mounting position.
  • the lock bit In order to be able to actuate the bolt of the lock, the lock bit must be turned into its working position after fastening the actuating device in the lock, in which it locks onto the bolt of the Castle can act.
  • the lock bit is coupled with the same or similar lock bar design and corresponding rotary position as with the lock bit of the lock cylinder.
  • the bolt usually has a recess which is open at the edge and into which the lock bit can enter. If you turn it further in the same sense, it takes the bolt in the locking sense. Rotation of the actuating member and thus also of the rotary member having the lock bit in the opposite direction causes the bolt to be withdrawn, that is to say the unlocking of the lock
  • the locking bit is either shortly before the mentioned opening of the bolt or it already engages in it.
  • the lock bit of this actuating device in contrast to that of a lock cylinder which makes at least a 360 ° rotation, can only be rotated by a predetermined, limited angle of, for example, 50 °.
  • the stop member rests on one stop surface and in the other end of rotation position on the other stop surface of the rotation limiting device.
  • the distance between the two stop surfaces is selected so that with a lock bit of a predetermined thickness - Seen in the direction of movement - the full intended bolt stroke can be carried out.
  • the stop surfaces are arranged and designed so that the coupling between the bolt and the lock bit is maintained perfectly throughout the bolt stroke, although the bolt performs a sliding movement and the lock bit rotates.
  • the position of the bolt can be seen from a distance.
  • a 90 ° locking stroke is common for bathroom doors, for example.
  • the stop member and the two stop surfaces must also be attached so that the torque given by hand can only cause a sliding movement of the bolt and no other transverse force. This means that after the latching element has snapped in between the two stop surfaces, the coupling between the rotating element and the housing is always retained during normal operation. On the other hand, you have to design the corresponding parts so that you can get into the spring-locked locked working position by the rotary movement of the rotary member from the mounting position to the working position without any significant effort.
  • the stop member must therefore be under a spring-elastic tension before snapping between the two stop surfaces, which allows the snap-in as soon as the entire width of the stop member - measured in the direction of rotation - has been turned past one of the two stop surfaces or vice versa.
  • the stop member must consequently before Lock in a plane that is measured in the direction of the axis of rotation, in front of the plane of the two stop surfaces. At this level it can already be in the. Installation position of the actuating device are located or it must be brought into it in a suitable manner in good time before one of the two stop surfaces is reached.
  • the resilient force can be a resilience of a resiliently deflected part or the force of a load spring that is under tension as long as the stop member is in front of the plane of the stop surfaces or vice versa.
  • the rotary member has two protruding, in particular molded bearing pins protruding on opposite sides, each of which engage in a bearing bore of the housing, at least one of these bearing bores being located on a part of the housing which can be deflected in the axial direction approximately in the axial direction.
  • the use of a separate spring for the latching movement can therefore be dispensed with, rather the spring force is obtained from the spring-elastic deflection of the elastically deformable housing part. The latter assumes its normal position as soon as the stop member has snapped into the space between the two stop surfaces.
  • the pins and the bore lengths must be chosen so that despite the spring-elastic deflection at least one of these two bearing bores from their working plane still securely engage both pins in the bearing bores so that the rotating member rotates properly from the Installation position in the working position is guaranteed.
  • a further embodiment of the invention is characterized in that the housing is essentially U-shaped and both U-legs form a deflectable part of the housing, the housing preferably being made of plastic.
  • Plastic is ideally suited not only for inexpensive production, but also because of its good spring-elastic properties. In this case, a symmetrical configuration with respect to a central plane of the actuating device arranged perpendicular to the axis of rotation is appropriate.
  • a particularly preferred embodiment of the invention results from claim 4.
  • the rotary member is identical both at its left and at its right end and the same applies to the two U-legs of the housing.
  • the side spacing of the two U-legs of the housing is selected so that in the area of the pivot bearing the two inner surfaces rest snugly but not in an inhibiting manner on the respectively assigned end face of the rotating member. If the actuating device is to be installed in a lock prepared for a profile cylinder, the contact surface for the rotary member has an annular shape and at its lower end in the installed position the stop member protrudes inwards.
  • the rotary member can be actuated at all after assembly of the actuating device, it must be able to be coupled to an actuating member. This is achieved in a simple manner by a central axial bore of the rotary member for receiving a mandrel or the like.
  • the actuating member in particular by a square bore. In the latter case, the usual dimensions are used, so that instead of an actuator, at least initially, for example during construction, any conventional handle with a square actuator can be used.
  • the U-center piece of the housing is provided with a fastening thread, the axis of which runs perpendicular to the axis of rotation of the rotary member and of course also the corresponding distance from the Has axis of rotation.
  • a fastening thread the axis of which runs perpendicular to the axis of rotation of the rotary member and of course also the corresponding distance from the Has axis of rotation.
  • this actuating device consists of only two individual parts, both of which can be easily manufactured from plastic, in particular injection molded. These two parts can be connected to each other in a matter of seconds due to the resilient properties of the housing. Reworking of the parts can usually be avoided, machining only occurs in the area of the fastening thread, if such is provided.
  • the actuating device consists of only two parts, namely the rotary member 1 and the device housing 2, both parts being made of plastic.
  • a plastic with resilient properties is used in particular for the housing 2 because the housing 2 is expanded in the direction of the arrows 3 and 4 during assembly.
  • the rotary member 1 can be used in the direction of arrow 5.
  • the cross-sectional shape of the housing 2 corresponds to that of a conventional profile cylinder in the exemplary embodiment, so that it can be inserted into the receptacle of a lock, the housing of which has corresponding openings.
  • the housing 2 is essentially U-shaped, the two U-legs 6 and 7 consisting of flat, plate-shaped elements which are designed in the form of a circular arc at their free end and each have a bearing bore 8 or 9.
  • the bearing pins 10 and 11 of the rotary member snap into these two bearing bores as soon as the latter is inserted deeply enough in the direction of arrow 5 between the U-legs 6 and 7.
  • the rotary member 1 is equipped with a central axial bore, in particular a square bore, 12, into which an actuator with a corresponding square mandrel can be inserted after the actuating device has been installed in a lock, door or window. Furthermore, the locking bit 13 projects radially from the rotary member 1. 4 is in its assembly position between the two U-legs 6 and 7, so that it does not protrude beyond the cross-sectional contour of the housing 2. In contrast, it protrudes beyond this cross-sectional contour when it is in its working position. In Fig. 3, the one rotary end position of the lock bit 13 in its working position can be seen with solid lines, which is assigned to the ineffective position of the lock bolt.
  • the rotation limitation of the rotary member 1 and thus also the locking bit 13 in its working position is achieved with the aid of a rotation limitation device. It consists of at least one stop member 14 of one part and two stop surfaces 15 and 16, offset in the rotational or circumferential direction, per stop member on the other part. In the exemplary embodiment, two stop members are provided, these being located on the housing 2. As a result, there are two pairs of stop surfaces on the rotating member. As can easily be seen from the drawing, the actuating device is designed symmetrically with respect to a longitudinal center plane running perpendicular to the geometric axis of rotation 17.
  • the inner surfaces of the two U-legs 6 and 7 of the device housing 2 form, at least in the area of the bearings 8 and 9, contact surfaces 18 and 19 for the respectively assigned, face-end, annular segment-shaped contact counter surface 20 and 21 of the rotary member 1.
  • the two stop members 14 point inside the housing and thus exactly against each other. In other words, they protrude into the gap 22 of the housing 2 defined by the two U-legs.
  • the two end faces of each stop member 14 form stop counter surfaces 23 and 24 (FIG. 3) for the associated stop surfaces 15 and 16 of the associated stop surface pair. 3, they run perpendicular to the image plane and thus parallel to the geometric axis of rotation 17. In addition, they are arranged at least approximately radially. Because the abutment surfaces 15 and 16 (FIG.
  • the stop surfaces 15 and 16 limit, as can be seen in particular in FIG. 2, a latching groove 25 on each side of the rotary member 1 for the stop member 14. However, as mentioned, it only engages in the working rotary position of the rotary member 1.
  • a locking groove 26 is also provided on each side of the rotary member 1. Seen in the circumferential direction, it is shorter than the latching groove and accommodates the associated stop member 14 in the mounting position of the actuating device. However, the transition from the bottom of the locking groove 26 to the contact surfaces 18 and 19 does not take place in the locking groove via vertical end faces but via inclined end faces 27 and 28 forming run-up bevels. When one of these inclined end faces 27 or 28 hits the stop counter surface 24 or 25 of the stop member 14 when the rotating member 1 rotates in one direction or the other, the inclined end surface 27 or 28 of each side causes the U-legs 6 and 7 to spread apart in the direction of the arrows 3 and 4.
  • a fastening thread 30 is located on the U center piece 29 of the device housing 2, similarly to conventional profile locking cylinders.
