Definitions

  • the invention relates to an overrun tongue for a cam lock or the like.
  • Screw-in sash lock with a torsionally rigidly attached to the end of the actuating shaft of the lock central part, from which a lever part extends radially away, which at the end merges into a tongue part, one in forms a substantially part-circular arc-shaped friction surface running around the actuating shaft axis, which has a run-off bevel in the direction of both ends.
  • a good rear rub can only be achieved with a sufficiently large tongue width.
  • the larger the tongue width the longer the ramp surface and the flatter its inclination, which can make the closing process much easier.
  • tolerance compensation must be as large as possible so that the door does not have to be pressed against the force of the seals when closing to the extent that when the lock is actuated, the tongue engages behind the door frame in the first place.
  • This construction makes it possible to change the angular orientation of the overrun tongue with respect to the actuating shaft as required, for example in steps of 90 ° with a square cross section of the actuating shaft end and a correspondingly adapted cross section of the opening in the central part of the tongue. If, however, a fastening nut is used for fastening the central part of the overrun tongue on the actuating shaft end, care must again be taken to ensure that this tongue fastening nut does not hinder the sliding of the sash lock fastening nut.
  • a further constriction can be provided between the neck part and the central part according to a development of the overrun tongue according to the invention, which allows the closure fastening nut to be slipped over the shaft end with the tongue fastening nut.
  • This constriction can advantageously be formed by two opposing depressions.
  • Fig. 1 is a side view of a so-called rotary bolt or sash door lock, as it is often used in electrical control cabinets. It consists of a lock bearing 10, in which an actuating shaft 14 having a toggle handle 12 at its free end is rotatably supported by 90 °. The angle of rotation is limited by a nose 16, which is attached to the actual grater or tongue 18 and strikes two stop surfaces 20 of a depression at the end of the bearing cylinder 10 to limit the angle of rotation.
  • FIG. 4 shows a top view of an overrun tongue which can be used in conjunction with a sash lock according to FIG. 1 and which avoids the disadvantages described above.
  • the advantageous single-hole mounting, as permitted by the cam locks according to FIG. 1 is possible, on the other hand, however, the overrun tongue has a friction surface extension which corresponds to the embodiment according to FIG. 3.
  • the overrun tongue consists of a central part 48 which is fixed in a torsionally rigid manner on the end of the actuating shaft 14, from which a lever part 50 extends radially away in one piece and at the end merges into a tongue part 52 which forms a friction surface 56 which extends essentially in the form of an arc of a circle around the actuating shaft axis 54, which has an overrun bevel 58 in the direction of both ends of the tongue part 52, see FIG. 5, which shows a view from the left of the outer tongue shown in FIG. 4. Between the two inclined surfaces 58 there is a flat surface 60 with which the overrun tongue rests on the door frame in the closed state, so that none of the ver conclusion to try to open torsional forces due to the slope 58 can occur in the closed state.
  • the closure with its overlay tongue 18b can also be threaded through the corresponding hole in the door leaf 26 before this nut 34 is pushed on, since the inside diameter of the hole corresponds to that of the nut 34 or even by the thread height is larger.
  • the central part 48 of the overlay tongue 18b can be welded or riveted to the end of the actuating shaft 14, since disassembly of the overlay tongue for the purpose of fastening the sash lock in a door is not necessary according to the invention.
  • it will be preferred in most cases to make the overrun tongue 18b nonetheless detachable for example by providing the central part 48 with a prismatic, in particular square aperture 66 with which the overflow tongue 18b has a corresponding cross section on the end part of the Actuating shaft 14 can be plugged on, so that there is a torsionally rigid connection.
  • the central part 48 can then be fixed on the shaft end either with the aid of a screw 22 according to FIG.
  • overrun tongue 18b is fastened in this way by means of a screw or nut 21, 22, care must of course again be taken to ensure that this type of fastening does not hinder the threading of the closure through the door leaf opening or the pushing over of the fastening nut 34.
  • the depression 66 could be continued over the entire lever part 50, see the dashed lines 70 in FIG. 4, but this continuation is for the pushing over of the fastening nut 34 as well as for the threading of the closure through the door opening not absolutely necessary.
  • the overrun tongue in its entirety, as shown in FIG. 4, for example, can be produced in a single stamping-deep-drawing operation, which results in a particularly stable and economical design.
  • a z. B. circular curved ramp surface can be provided, whereby the pressure forces can be increased shortly before reaching the flat surface 60 with the same actuation torque, which can be favorable with certain sealing strips reduced flexibility.
