Definitions

  • the invention relates to a permutation lock with a cam disc which can be actuated by means of a rotary knob for setting a plurality of setting secrets, the circumference of which is provided with a tumbler disc each with an incidence recess, with an engagement lever articulated on a bolt which has a nose or the like engaging on the circumference of the cam disc. and has a lateral finger, which is arranged transversely over the circumferences of the tumbler disks, wherein for the entry of the finger into the associated recesses of each tumbler disk, when these are aligned with one another under the finger, an aperture for the latch lever is provided on the circumference of the cam disk, and wherein a cam of the cam disc is also provided for moving the bolt into its closed position.
  • Permutation locks of this type are known, for example, from DE-A-23 20 816 and DE-A 2816 969. With such permutation locks, it is possible to exclude the bolt with the help of the rotation of the cam disc, that is to say to move it into the closed position so that the tumbler discs have not yet been twisted or rejected. This can be a convenience for the frequent user of this permutation lock, because he then does not have to first set the number sequence according to the setting secret to reopen the lock. Such a bar, which is closed or closed, of course, does not perform its function properly. “Excluding” the bolt is understood to mean the closing movement that brings the bolt out of the lock into its closed position in the lock counterpart.
  • the solution to this problem consists essentially in the fact that a coupling is provided on the bolt which can be moved out of the region of the cam path of the cam disk for the bolt movement and which can only be brought into the region of the cam path after at least partially twisting at least one tumbler plate , only then to implement the rotary movement of the rotary knob in a displacement of the bolt in its closed position.
  • the principle of the invention is thus practically to delay the bolt movement by the releasable intermediate coupling mentioned and by disengaging it until at least one tumbler disc is rotated sufficiently far by the turning of the knob in the closing direction to prevent the finger of the lever in the orderly and aligned recesses could again occur.
  • the user of the lock therefore inevitably rotates at least one, or several, or all tumbler disks in a configuration of the invention described later, when carrying out the closing movement of the bolt.
  • the coupling is fastened to the bolt and is designed as a pivotable coupling lever which can be pivoted into its coupling position in particular by means of a projection located on a tumbler disc via a linkage.
  • a pivotable coupling lever which can be pivoted into its coupling position in particular by means of a projection located on a tumbler disc via a linkage.
  • the length of the lever which can be lifted out from behind a locking stop prior to the twisting of the tumbler disks for carrying out the closing movement can be changed. It is thereby achieved that the rotary knob is turned and the lever and its finger can already be lifted out of the recesses in the tumbler discs without the bolt already being moved. First and foremost, a shortening of the drop lever is possible, so that the drop area having the nose can already be raised and brought behind the locking stop without the corresponding movement of the lock taking place at the other end. If the initially delayed bolt movement is then carried out, the drop lever is lengthened again accordingly.
  • the drop lever is designed as a toggle lever attached to the bolt, one of the toggle levers of which is articulated directly on the bolt and can be swung up when the drop lever is raised while shortening the entire drop lever.
  • a stop can be provided on the side facing the bolt for extending the insertion lever when the bolt is excluded. If the rotary knob has been turned so far that the clutch lever has been pivoted into the functional position, the further rotary movement leads to the aforementioned exclusion movement of the bolt, which leads to a corresponding displacement of the articulation point of the toggle lever leg of the drop lever. If the toggle joint is now prevented from doing this movement, the entire toggle lever and thus the drop lever are stretched again. After a certain stretch, even the toggle joint can fall into its final locking position due to gravity.
  • the locking position of the bolt is often monitored by electrical means. However, this is of no use if the lock is not turned into a really secure position, i.e. if the tumbler disks have not all been discarded.
  • the present invention therefore has the additional advantage that such bolt monitoring can now be carried out in a really sensible manner.
  • a permutation lock designated as a whole by 1, hereinafter also referred to as lock 1 for short, has a cam disk 3 which can be actuated by a rotary knob (not shown in more detail) via a shaft 2 for setting a plurality of tumbler disks 5 which can be adjusted to any setting secrets and are provided on their circumference with a recess 4 each Furthermore, the lock 1 has an engagement lever articulated on a bolt 6, generally designated 7, which has a nose 8 engaging on the circumference of the cam disk 3 and a lateral finger 9 which is arranged transversely over the circumferences of the tumbler disks 5, wherein for the entry of the finger 9 into the associated recesses 4 of each tumbler disc 5, when these are aligned with one another under the finger 9, an incidence opening 10 for the lever 7 is provided on the circumference of the cam disc 3. On the cam disc 3, a cam 11 is also provided for moving the bolt 6 into its closed position.
  • a clutch lever 12 to be described in more detail below - is provided, which only after at least partially rotating at least one Locking disc 5 in the coupling position (FIG. 5), ie in the area of the path of the cam 11 is brinbar.
  • the clutch is fastened to the bolt and, as already mentioned, is designed as a pivotable clutch lever 12 which can be pivoted into its clutch position in particular by means of a projection 13 located on a tumbler disc 5a (see FIG. 1) via a linkage to be described.
  • the drop lever 7 is designed as a toggle lever attached to the latch 6, one of the toggle levers 15 of which is articulated directly to the latch 6 and when the drop lever 7 is lifted out, the entire drop lever is shortened to the position shown in FIG. 4 can be swung up.
  • a stop 17 is provided on the side facing the bolt 6 for extending the drop lever 7 when the bolt 6 is excluded. If the bolt 6 is shifted from the position shown in FIGS.
  • the projection 13 designed as a pin in the exemplary embodiment which of course could also be a recess into which a pin or the like element can fall from the other side, and serves to actuate the clutch lever 12 cooperating with the cam disk 3, is in the exemplary embodiment arranged on the last tumbler disc 5a seen from the cam disc 3, so that all tumbler discs must first be rotated before the clutch lever 12 reaches the engaged position according to FIG. 5 and the bolt 6 can be excluded by further rotation of the shaft 2. Under no circumstances does this exemplary embodiment enable the bolt 6 to be so narrowly excluded that the lock 1 could be opened again immediately without the opening secret having to be reset. At the same time, conclusions on the difference between the individual opening numbers are made impossible from the outset by this measure.
  • the coupling lever 12 articulated on the bolt 6 has two end positions which can be releasably fixed. This can be done in a manner not shown with the aid of locking balls and the like.
  • a magnet 19 engaging the clutch lever 12 itself or its actuating linkage is provided for the top position of the clutch lever 12, that is to say its disengaged state. This can hold the clutch lever 12 securely in the up position, but exerts practically no force on this lever after adjusting the clutch lever in the clutch position, in contrast to a return spring.
  • the cam 11 of the cam disk 3 is shaped and rounded in particular in its upper region at the transition 20 into the contour corresponding to the outer circumference of the cam disk 3 so that when the bolt 6 is closed to open the lock 1 on the correspondingly beveled and also engages the rounded end 21 of the clutch lever 12 and pivots it upwards. It is readily understandable and recognizable in the figures that when the cam disc moves against the arrow Pf 2, the area 20 detects the cam-shaped end 21 of this clutch lever when it protrudes into the contour of the cam disc 3 according to FIG a further rotation to the position shown in FIG. 3, where the clutch lever 12 can then be held by the magnet 19.
  • the actuating linkage which has already been mentioned a number of times, via which the clutch lever 12 returns to the clutch position, is formed in the exemplary embodiment in that on the inside 22 of the lock housing or lock case 23 facing away from the cam disk 3, a control lever 24 can be acted upon by the pin-like projection 13 of the tumbler disk 5a for control purposes of the clutch lever 12 - in the exemplary embodiment on a stud 25 - is mounted, which control lever 24 preferably has a slot guide 26, into which a pin 27 connected to the clutch lever 12 (cf. especially FIG. 1) engages.
  • control lever 24 consists of a partly stamped, partly varnish edged sheet metal part, the guide slot 26 being formed by angled legs 29. These legs 29 for forming the guide slot 26 could also be attached to a corresponding control lever 24.
  • a counter force directed against its locking movement i.e. against the arrow Pf 1
  • Shortening the drop lever 7 can result in a premature, at least partial exclusion of the bolt 6 in the direction of the arrow Pf 1.
  • the toggle lever geometry of the drop lever 7 is chosen so that when the drop lever 7 is stretched in the locked position according to FIG. 2, the imaginary connecting line from the locking edge 30 of the drop lever 7 to the swivel joint 18 on the bolt 6 extends above the toggle lever joint 16 and that the connecting line from that Point of engagement 31 of the cam disk 3 on the nose 8 of the drop lever 7 to the swivel joint 18 on the bolt 6 runs below the middle toggle joint 16, a support 32 being provided downward for the toggle joint 16 to fix this position.
  • an actuating pawl 34 is provided on the free end of the control lever 24, the front side 35 of which is concave, this concave curve region of the front side 35 being arranged in such a way that that in the disengaged state (cf. especially Fig. 4) cuts the swivel circle of the projection 13 located on the tumbler disc 5a, while in the coupled state (cf. Fig. 5) this contour of the clamp 34 with the swivel path of the outermost point or the outermost surface line 36 of the projection 13 of the tumbler disc 5a approximately coincides.
  • the center point of the circular arc forming the concave contour of the end face 35 of the pawl 34 of the control lever 24 lies to the side of the imaginary center line through the pawl 34 and its pivot bearing 37, so that the contour into the coaxial position only becomes when the control lever is pivoted into the coupling position reaches the center of the cam disk 3.
  • the pawl 34 is namely pivotally mounted relative to the control lever 24, the pivoting path of the pawl 34 on this control lever 24 in the direction of the coupling movement being limited or prevented by a stop 38 and a counterforce in the opposite pivoting, in the exemplary embodiment the force of a spring 39 must be overcome. This makes it possible to turn the tumbler disc 5a with the projection 13 in the position shown in FIG. 4 against the direction of the arrow Pf 2 without damage to this projection or the pawl, because then the pawl 34 is the projection 13 can escape under tension of the spring 39.
  • the bolt movement itself is formed in a known manner by a guide pin 41 engaging in an elongated slot 40 and a projection 43 connected to the bolt and sliding on the inside of the lock case 42.
