Definitions

  • the invention relates to a cylinder lock, consisting of a fixed in an outer cylinder provided with two 180 0 offset longitudinal recesses inner cylinder in which a spring-less plate-shaped tumblers bearing cage cylinder is rotatably arranged, and the tumbler plates are controlled by a key, whose upper and lower edge is profiled so that the distance between the upper and lower edge (profile width) is the same at the different profile levels and the tumbler plates for the key passage have window cutouts, the distance between the upper and lower edge of a window cutout corresponding to the profile width of the key, so that the tumbler plates are positively controlled in their longitudinal movement by the key profile in both directions, in such a way that when the key is inserted into the lock cylinder, the tumbler plates are all in their open position.
  • Known cylinder locks with plate-shaped, springless tumblers are locked when the key is removed by the fact that the tumblers by gravity in engage a longitudinal recess in the outer cylinder.
  • the inner cylinder is blocked against twisting. All tumblers lie on the bottom of the locking groove and are therefore at the same height or in the same immersion depth.
  • Such a cylinder lock can now be opened quite easily by unauthorized persons, for example by inserting a hard round brush through the keyhole, which is firmly attached to the inside of the windows in the tumbler plates. Due to the friction of the bristles, it is possible to simultaneously lift the tumbler plates until they are all in the open position. The inner cylinder can now simply be turned and the lock opened.
  • This opening possibility can be eliminated by designing the immersion depths of the tumbler plates in the locking groove differently. It is known to carry out the longitudinal movement of the tumbler plates by means of projections and corresponding recesses on the side flanks of the tumbler plates or on the cage cylinder. A particular problem is the execution of such a lock, which should be inexpensive to manufacture the individual parts and easy to assemble. It is easily conceivable to divide the cage cylinder carrying the tumblers or to assemble it from disks. The cage cylinder could be filled with the tumbler plates before assembly with the outer cylinder and then inserted into the outer cylinder. The usual assembly is not possible due to the projections and recesses. An embodiment with a divided cage cylinder or disc-shaped cage cylinder is complex and expensive both in the manufacture of the parts and in the assembly.
  • the object of the invention is therefore to provide a cylinder lock of the type described above, which is simple and inexpensive to manufacture and quick and easy to assemble.
  • This object is achieved in that in order to limit the longitudinal movement of the tumbler plates in their guide slots on both outer flanks of the tumbler plates at the same height and with equal longitudinal cutouts, and a beam protruding into these longitudinal cutouts, provided over the entire length of the cage cylinder, which is provided in a can be slid in the cage ut cylinder provided for this purpose and N so as to project which limits the longitudinal movement of the tumbler plates into the longitudinal cut-outs.
  • the tumbler plates can be mounted as in a known cylinder lock without limiting the immersion depths of the tumblers.
  • the tumbler plates with the recesses in their side flanks are simply inserted into an undivided cylinder before assembly. Only now is a bar simply inserted into the longitudinal groove in the inner cylinder, which now engages in the cutouts on the tumbler plates and limits their movement in both directions.
  • This arrangement also makes it possible to easily change the combination number of the lock by changing tumbler plates if a key has been lost or gotten into someone else's hangers.
  • the bar is located in a central axis of the cage cylinder which is transverse to the longitudinal movement of the tumbler plates, as a result of which the bar also rotates the longitudinal movement of the tumbler plates in their reverse as well as in 180 degrees Can limit location.
  • Another feature of the invention is that the length of the longitudinal cutouts on the side flanks of the tumbler plates is dimensioned such that their depth of immersion in the longitudinal recesses is different in both directions of movement.
  • a key 1 is in the windows of the tumblers 3.
  • the key has five step heights, the distance 2 between the upper and lower profile edge being the same in all steps.
  • the distance between the top and bottom edges for the insertion The window cutouts provided for the key is the same as the width of the key profile 2 for all tumbler plates.
  • the window sections are offset in the individual tumbler plates so that the outer edges 3a of all tumbler plates are at the same height when the key is inserted. Since the height differences between the five stages of the key profile 1 are all equal, the particular for the profile height 1 tumbler plate 3 can be rotated through 180 0 also be used for the profile height. 5 In the same way, the tumbler plate for profile height 2 can also be used for profile height 4, so that only three differently manufactured tumbler plates are required for the embodiment shown.
  • a fixed inner cylinder is arranged in an outer cylinder 7, which is flattened on its top and bottom, so that there are an upper and lower locking groove 8 and sharp edges 9.
  • the tumblers 3 have longitudinal cutouts 11, 11a and recesses 10 on their side flanks.
  • a bar 14, which engages in the longitudinal cutouts 11, 11a, is inserted into a groove 15 in the region of the longitudinal cutouts 11, 11a.
  • a double key 1, 1a formed from two key halves is shown, the two key halves of which have different profile sequences.
  • recesses 10 are provided on the two lower side flanks of the tumbler plates, which get caught on the edges 9 of the inner cylinder when the cage cylinder is turned in its closed position. These recesses 10 are provided only on one side of the tumbler, so that, when the same tumbler plate 180 0 twists used in another guide slot, the other edge also prevents smooth rotation of the cage, the smallest cylinder.
  • Different immersion depths 16 in the lower locking groove 8 are achieved in that the longitudinal cutouts 11, 11a of the individual tumbler plates 3 are of different lengths. These longitudinal cutouts 11, 11a in connection with the extension of the bar 14 limit the movement of the tumblers 3 into the locking groove 8 after the key has been removed, and the tumblers 3 are placed at different heights or immersion depths.
  • the dimension 4 (FIG. 2) at the recess 11 must be at least as large as the height 4 (FIG. 1) of the profile height corresponding to the tumbler plate, calculated from the lowest profile height. This dimension 4 determines the immersion depth 16 of the tumbler plate 3 in the locking groove 8.
  • the dimension 4a determines the immersion depth in the upper locking groove 8 and can be selected independently of the profile height.
  • the total length of the recess 11 is then equal to the sum of the dimension 4 plus the dimension 4a and the thickness of the bar 14.
  • FIG. 3 shows a tumbler plate 3 (window section not drawn) which, when the key has been pulled out, has fallen down into the locking groove 8 and whose movement is limited by the bar 14.
  • Figure 4 shows the cage cylinder during the assembly of the tumblers. As long as the bar 14 has not yet been pushed into or pulled out of its groove, the tumbler plates can be pushed freely into the guide slots of the cage cylinder.
