Definitions

  • the invention relates to a combination of a flat key and a locking cylinder with pin tumblers, with a cylinder housing in which a core with a circular cross section with a longitudinal profile or longitudinal rib profile is rotatably mounted in the key channel for the flat key with variable cutouts provided on the narrow sides, and with itself to the core longitudinal axis transversely extending spring-loaded tumblers, which are each arranged in a row or in rows in levels which, for. B.
  • DE-A-3 603 687 also relates to a locking device consisting of a locking cylinder and associated flat key, in which the flat key in the area of its back zones opposite the narrow notch side has a guide cross-section which cannot be cut out even by the deepest locking notches and which has a guide groove on one broad side , which is provided in addition to the profile variation grooves / ribs arranged on both broad sides, and which guide section in its end region facing the roof-shaped key tip has a widening open towards the tip for retracting a nose on the key channel side, the flank lying on the closing groove side of the widening lying overlying the guiding groove at its end facing the key tip merges into a first run-on bevel that runs out on the closing notch side of the tip, which opposite one another at a greater distance from the tip opposite, inclined second run-up slope, the distance from the End of the widening is greater than the diameter or the thickness of the nose with rounded outer zones, which sits on the side flank of a supplementary tumbler
  • the second bevel opens into the back flank of the flat key.
  • the locking device is also characterized in that the flank of the widening on the closing notch side forms a slideway closer to the back flank following the first run-up slope, which slides into the end section of the widening in parallel with the second run-up slope.
  • the supplementary tumbler is arranged in the open position with both front ends on the lock cylinder core joint and the distance of the nose from one end of the supplementary tumbler is equal to the height distance of the slideway from the lower flank of the end section.
  • the locking device is provided by a plurality of supplementary tumblers one behind the other in the direction of insertion with lugs lying in the open position at different distances from the back surface and a corrugation of the rear end section of the widening associated therewith.
  • the depth of the widening is smaller than that of the guide groove.
  • the control device consists of a control pin which is under the action of a compression spring which is stronger than the pin spring of the tumbler pin pair with which the control pin cooperates and that the control pin rests on the roof surface of the core pin when the key is not inserted.
  • the control pin should be mounted in a hole that penetrates the end of the cylinder core centrally in the direction of the longitudinal axis of the cylinder core.
  • two mutually resiliently supporting control bolts each penetrating one of the cylinder core ends, are provided. In its locked position, the locking core pin only projects into the key channel with its rounded or conical end.
  • FR-A-2 388 966 shows a cylinder lock with a lock cylinder, to which a rotatable core is assigned, which has a key channel in which a flat key can be inserted, which is provided with longitudinal rib profile, which cooperate with tumblers, the lock housing being connected by a Jacket is protected from a relatively hard material, which can consist of hardened steel, for example.
  • the cylinder lock is assigned a slide at its rear, inner end, which controls a rod-shaped element. The slide engages in a notch in the flat key designed as a longitudinal rib profile flat key.
  • DE-A-3 225 952 shows a lock cylinder flat key with at least one lateral recess for entry of the inner ends of cylinder core pins, the recess open to the tip end of the key being equipped with undercut longitudinal flanks for withdrawing the one equipped with a form-fitting head Cylinder core pin.
  • This depression is designed as a dovetail-shaped groove and the head in the form of a truncated cone. The cross-section of the depression channel widens on the mouth side. The groove has a lateral widening opening from the cross section of the head.
  • the invention has for its object to provide a combination of a flat key and a lock cylinder with pin tumblers, the security against unlocking, unlocking and scanning security is increased considerably.
  • "Unlocking security” means the degree of difficulty in non-destructively overcoming the locking elements of a locking cylinder with tools without knowledge of the associated key.
  • Locking security is the degree of difficulty in operating the locking cylinder with a key other than the associated key.
  • “Scanning security” is to be understood as the degree of difficulty in determining the locking coding of the tumblers of a locking cylinder using suitable aids without using a force and without a trace in order to produce a duplicate key according to the determined values (dimensions).
  • the key Because a protective body is arranged in the deepest part of the key channel in the area of the key tip, the key must be specially designed so that it can be inserted and fits into the key channel as far as it will go.
  • the position of the locking slide with respect to the protective body can be determined so that normally no locking tools can be pushed between the protective body and locking slide.
  • the previous break-in method can no longer be used, which consists in inserting a picking gun or other picking set into the key channel in order to push up the core pins and at the same time the core in Keep the circumferential direction under tension.
  • the spring forces that load the various, displaceably mounted core pins, the indexing pin and the locking slide are of different sizes. Impression technology, however, uses a material that reacts to pressure. Places are then worked away based on prints. If this were to be carried out with the lock according to the invention, it would lock the lock immediately because imitations are made that cannot be removed.
  • a lock cylinder according to the invention is easy to manufacture.
  • the protective body is connected to the core.
  • This connection can be made by inserting the pin-shaped or rod-shaped protective body into a bore in the core under prestress. Because the protective body is inserted through a bore orthogonal to the longitudinal axis of the core and passes through the key channel in the area of the key tip, there are particularly narrow spaces between the core pin, protective body and any indexing pin, so that locking tools can hardly be used to push back the locking slide.
  • the special design of the locking cylinder results in an indexing of the core, so that a radial clamping of the tumbler pins is eliminated. The spring back of the indexing pin pushes the key back into the open position.
  • the distance between the indexing pin and the protective body at the entry of the key tip can be kept particularly small, making manipulation with locking tools even more difficult.
  • there is a good introduction of the forces into the cylinder core at the shortest distance which means that the locking slide cannot be tilted.
  • such a locking slide can be manufactured inexpensively and stably.
  • An embodiment according to claim 2 is easy to manufacture.
  • An embodiment according to claim 4 is easy to manufacture in terms of production.
  • the core pin is lifted over the slope and the locking slide so that it locks the core against the cylinder housing.
  • a further core pin lying in front of this core pin then rests with its longitudinal end face on the incline.
  • the locking position is precisely determined, since a defined locking position results in the front position of the locking slide by striking the flag against the protective body.
  • claims 15 to 18 ensure that the unlocking security, the locking security and the scanning security are increased considerably. In particular, it is then no longer possible for impressions to be made in accordance with the impression technique in order to form corresponding recesses on a blank and thereby produce a duplicate key. Since no system is recognizable for an outsider, the key features of the key blank cannot be prefabricated in order to adapt them to the lock setup. Rather, the internal arrangement and design of the lock components are completely unknown to an outsider. Without destroying the lock, opening is no longer possible without the right key.
  • Reference number 1 in the drawing denotes a cylinder housing in which a core 2 is rotatably mounted.
  • housing pins 3 are arranged longitudinally displaceably in parallel and at a distance from one another against the restoring force, in each case at least one spring element 4.
  • a core pin 5 is assigned to each of the housing pins 3.
  • Each of the core pins 5 is mounted in a bore 6 in the core so as to be longitudinally displaceable. All core pins have a circumferential bevel in order to enable them to be lifted by the key tip and to be immersed in the cutouts 7 of a flat key 8.
  • the flat key 8 can also be designed as a longitudinal rib profile flat key.
  • the reference number 9 denotes a key channel.
  • the key back is designated by the reference number 10.
  • the flat key 8 has an auxiliary slot 11 in its tip, the transverse dimensions of which are dimensioned such that the key with the two key tips 12 and 13 formed thereby encompasses a rod-shaped protective body 14 with little play on opposite sides .
  • the rod-shaped protective body 14 runs with its longitudinal axis orthogonal to the longitudinal axis of the flat key 8 and also orthogonal to the longitudinal axis of the core 2.
  • the rod-shaped protective body 14 is arranged with its end sections in a bore 15, the protective body 14 being held in the bore by pretensioning. With its central length section, it passes through the key channel 9.
  • an indexing pin 16 is arranged diametrically opposite and with its longitudinal axis orthogonal to the rod-shaped protective body 14 is arranged on the side of the cylinder housing facing the key spine 10.
  • This indexing pin 16 is attached to a clamp spring 17, which is the cylinder housing 1 engages and (Fig. 15) is arranged in grooves 18.
  • the clamp spring 17 engages around the cylinder housing 1 under pretension.
  • the indexing pin 16 is mounted in a bore in the cylinder housing 1 against the restoring force of a compression spring 19.
  • the indexing pin 16 is tapered at its free end section facing the key channel 9 and ends with its tip at a short distance from the surface of the rod-shaped protective body 14. This distance must be dimensioned such that the flat key 8 with its key tip 12 penetrate this distance and can push the indexing pin 16 back to the parting plane between the cylinder housing 1 and the core 2.
  • the key tip 13 of the flat key 8 pushes the row of core pins 5 back to the separation level, except for core pins which are closer to the area of the key tip when these no longer protrude into the key channel 9 and which are described below.
  • a locking slide 21 is longitudinally displaceable, ie in the direction of the key longitudinal axis, against the restoring force of a spring element 22.
  • the spring element 22 is supported against an axially adjustable abutment 23, which is shown in the Embodiments is designed as a screw plug that can be screwed into a bore 24 with a thread.
  • FIGS. 1, 2, 5, 13 and 14 each have a blind bore 26 in which the spring element 22 is guided and supported.
  • a shoulder or shoulder 27 is integrally connected to the control nose 28, which is directed to the side of the cylinder housing 1 on which the key spine is located 10 is located.
  • a control lug 28 which has a run-on slope 29 is integrally connected to the locking slide in all embodiments.
  • the run-up slope 29 merges into a plane-parallel surface 30 with which the locking slide 21 rests on the recess guide 20.
  • the surface 30 runs plane-parallel to the support and guide surfaces 31, 32.
  • the guide surface is formed by the lateral surface 33 of a bore.
  • the control lug 28 is controlled by the end face of the flat key 8 starting from the key tip 13 and pushed back against the restoring force of the spring element 22.
  • FIG. 3 shows the starting position in which there is still no suitable flat key 8 in the key channel 9. If a suitable flat key 8 is now inserted into the key channel 9, the core pins are pushed back one after the other against the restoring force of the springs assigned to them down to the parting plane, since they can fall into the key cutouts 7 that match them.
  • the penultimate core pins shown in FIGS. 1, 3, 4, 5, 6 and 8, which are provided with an annular shoulder fall into the associated key incisions 7, while the pin which is furthest away from the key stop on the plane-parallel surface 30 of the Locking slide 21 slides up to the inclined support and guide surface (FIG. 4) 29 to surface 42, in which it also releases the separation between cylinder housing 1 and core 2.
  • a pin 34 which is fixedly arranged in the cylinder housing 1 is arranged behind the core pin 5 which is the most distant from the key stop.
  • This pin 34 has an end portion 35 in a longitudinal groove 36 of the locking slide 21, which locks when the flat key 8 is removed by the side walls of the longitudinal groove 36 of the locking slide 21 and releases the end portion 35 when a suitable flat key 8 is inserted into the key channel 9.
  • the penultimate core pin 5 has an annular groove which is formed by an approximately centrally arranged recess and which is dimensioned such that the locking slide 21 with its control lug 28 engages in this ring groove (z. B. Fig. 1, 6, 8 and 13) blocking.
  • This condition arises when the lock has been tampered with with an inappropriate key or intrusion tools. After that, the lock can no longer be opened with a suitable key. If such a lock is to be made functional again without destruction occurring, the locking tools shown in FIGS. 10 and 11, which consist of a screwdriver-like handle and a part made of spring steel, are particularly necessary.
  • this includes a special auxiliary key 38, which has a longitudinal groove 39 on one side, through which the locking tool 37 with its resilient part can be inserted in the correct position (FIG. 8).
  • the locking tool 37 moves below the penultimate core pin 5 (FIG. 8) and bumps against the rod-shaped protective body 14, whereupon it is deflected because of its elasticity and then bumps against the locking slide 21 and the latter pushed back against the restoring force of the spring element 22.
  • the control lug 28 emerges from the annular groove of the penultimate core pin 5 and allows the auxiliary key 38 to be pushed so that this previously locked core pin 5 can now be pushed up against the restoring force of the associated spring via the key tip slope of the key tip 13 and then the adjustment of the auxiliary key 38 to the control lug 28 of the locking slide 21 is permitted. Then the starting position shown in FIG. 3 is reached again, in which the lock can be operated again with a conventional, suitable flat key 8. Only the very small in its transverse dimensions, e.g. B. needle-shaped, resilient locking tool 37 is able to overcome the small transverse distance between the tip of the locked core pin 5 (Fig. 8) and the rod-shaped protective body 14.
  • a rigid element could not overcome the distance formed by the end face of the penultimate of the core pins 5 and the rod-shaped protective body 14.
  • dimension A measured from the longitudinal center line of said core pin 5, the center line running through the center point of the rod-shaped protective body 14 is 3.5 mm. If you draw a line orthogonal to the longitudinal axis of this core pin 5, which just touches the tip of this core pin 5 and the center line which runs through the center of the rod-shaped protective body, the highest point (tip) of the penultimate core pin 5 can touch this line but also be set back from this line by a few tenths of a millimeter. The line is identified in the drawing by reference numeral 40. Characterized in that the rod-shaped protective body 14 is rounded in its outer surface, a deflection of the free, spring-elastic end of the locking tool 37 is facilitated.
  • the core pins 5 which are the most distant from the key stop cannot be opened according to the Hobbian opening method because access to the free ends of these core pins 5 through the locking slide 21 is not possible. To do this, it would first be necessary to push the locking slide 21 back against the restoring force of the spring element 22. Should this nevertheless succeed, in such a way that the locking slide 21 is pushed all the way back until it stops, then these core pins 5 slide off the locking slide 21, so that the housing pins 3 block the core 2 relative to the cylinder housing 1.
  • the commercially available locking tools described in the introduction to the description cannot be used in a lock according to the invention in order to be able to unlock it without traces and destruction and without noise.
  • FIG. 4 A further embodiment of the invention can be seen from FIG.
  • a surface 42 is provided between the control lug 28 and the control surface or the bevels 29, on which the last of the core pins 5 rests with its tapered end surface when the locking slide 21 has been pushed back by the appropriate key against the restoring force of the spring .
  • the lock is unlocked (Fig. 4).
  • the cuts may vary. 18, these incisions have been indicated schematically with X1, X2, X3 and X4.
  • the length B of the surface 42 can also vary. This also applies to the shape.
  • the surface 42 can be designed to be concave, convex or in some other way, for example in a wave shape. It is also possible to arrange a rectilinearly delimited surface 42 not parallel to the core longitudinal axis 43, but at an acute angle to it.
  • Fig. 20 it can be seen that the control lug 28 can also engage in a recess 44 of the key.
  • the shape, dimension and distance of this recess 44 from the core longitudinal axis 43 can also be varied.
  • the thickness of the locking slide 21 has been designated D in FIG. 20. This dimension D must be smaller than the dimension H, measured from the tip of the penultimate of the core pins 5 to the transition of the conical part into the cylindrical part (Fig. 4).
