Definitions

  • the invention relates to a cylinder lock with a cylinder housing and a cylinder core, in the cylinder core one or more axially displaceable and according to their axial position enabling the rotation of the cylinder core locking bars are provided, the displaceability of which is controlled by a key inserted into a key channel.
  • the cylinder lock mentioned at the outset is characterized in that pin tumblers which are divided one or more times are provided, which are arranged in recesses in the locking strips and the cylinder core, can be displaced in the direction of the key channel and away from it, and are controlled by recesses or control surfaces of the key , so that the divisions of the pin tumblers are arranged with the correct key in the parting plane between the locking bar and the cylinder core.
  • the locking strips have locking pieces projecting radially outward into an axial recess, which, when the locking strip is in the released position, are aligned with annular grooves in the housing such that the axial displacement of the locking strip is given by a locking ring with run-up surfaces which interact with the running surfaces of the locking bar and that the locking ring with the cylinder housing via a Limit force clutch is connected.
  • the locking bar with projections preferably engages behind an undercut in the recess for the locking bar, as a result of which the locking bar is secured against displacement in the radial direction.
  • the pin tumblers and the associated bores can be offset, the portion of the pin tumblers closer to the key channel having the smaller diameter.
  • the one or more locking strips can be arranged with their parting plane parallel to the key channel, the control surfaces of the key being arranged on its side surfaces.
  • the section of the pin tumblers remaining in the locking bar preferably has a recess for the spring, the spring being supported with respect to the locking bar.
  • the second combination feature (basic profiles and variable profiles are nested, arranged in columns and rows) is shown in FIGS. 13 to 19.
  • 13 to 15 relate to an exemplary embodiment
  • FIGS. 16 to 19 illustrate another such example.
  • FIGS. 20 to 27 also relate to the second combination feature.
  • a cylinder lock is shown in elevation
  • Fig. 21 is the key to it
  • Fig. 22 shows a cross-section according to Fig. 20.
  • the profile according to the invention is in an enlarged section along the line XXIII-XXIII 21 can be seen.
  • 24, 25, 26 and 27 illustrate constructive details which are decisive for the understanding of the invention.
  • the drawings are partly schematic.
  • a cylinder core 2 is rotatably arranged in a cylinder housing 1.
  • a key 5 is inserted in the key channel 4.
  • a locking bar 3 is arranged in a recess 11 of the cylinder core. This recess 11 and the locking bar 3 extend in the axial direction of the cylinder core parallel to the key channel.
  • Each locking bar 3 is approximately T-shaped in cross-section, the projections 18 engaging in undercuts 10 of the axial recess 11. The locking bar 3 can be moved in the axial direction, but is held in the radial direction on both sides.
  • the locking bars 3 On the surface facing the housing, the locking bars 3 have massive locking pieces 16. In the position shown in the lock, ie when the key is in the inserted position, the locking pieces 16 protrude into the associated axially continuous recesses 19 in the housing. As a result of this axial recess 19, the lock can be moved freely pieces 16 and the locking bar 3 guaranteed in the axial direction.
  • annular grooves 17 are arranged in the housing.
  • the cross-section of the annular grooves 17 corresponds to the cross-section of the locking pieces 16.
  • the assignment of the locking pieces 16 and the annular grooves 17 to one another is such that, with a certain axial position of the locking bar 3, all locking pieces 16 are aligned with one of the annular grooves 17, whereby the cylinder core rotates freely can be.
  • Bores 12 for pin tumblers 6 are arranged in the locking bar 3.
  • the bores 6 extend on the one hand into the locking bar 3 and on the other hand in the cylinder core 2 up to the key channel 4. With a certain axial position of the locking bar 3, the bores of the locking bar are aligned with the associated bores of the cylinder core.
  • the bores 12 are stepped in the area of the cylinder core 2, so that the stepped pin tumblers can only protrude to a certain extent into the key channel.
  • the pin tumblers In the area of the locking bar 3, the pin tumblers have recesses 13 in which a compression spring 14 lies and prestresses the pin tumbler in the direction of the key channel.
  • the pin tumblers have graduations 8.
  • a division can be provided, but a plurality of divisions can also be provided by inserting intermediate plates 21.
  • the key 5 has recesses or control surfaces 7, which can be formed by blind bores due to the reasons.
  • the depth of the control surfaces 7 is variable, so that closing differences can be provided.
  • the tumblers 6 are under the pressure of the springs 14 with the correct key placed in such a position that the divisions 8 of all tumblers are aligned with the parting plane 9 between the locking bar 3 and the cylinder core 2. In this position, the locking bar 3 is displaceable in the axial direction.
  • the axial displacement of the locking strips 3 is made possible in a known manner by a locking ring 22 (FIG. 1).
  • the locking ring 22 is locked to the cylinder housing 1 via a limit force clutch 23.
  • the limit force coupling in this case consists of a ball catch with the ball 24, spring 25 and the conical recess 26 in the locking ring.
  • the locking ring 22 has recesses 27 for each locking bar 3 and each of the two components has contact surfaces 28, 29, which come into effect when the components rotate relative to one another.
  • the one contact surface 29 of the locking bar 3 abuts the associated contact surface 28 of the locking ring and the locking bar 3 is shown in the representation according to Pig. 1 shifted to the left.
  • the locking pieces 16 are then aligned with the radial annular grooves 17 and the cylinder core can be rotated freely.
  • the locking bar is returned when the cylinder core is turned back into the starting position by further run-up surfaces 30, 31 at the other end of the locking bar.
  • the run-up surfaces 31 are formed by an insert ring 32 which is inserted in the housing.
  • the run-up surfaces 30 sit on the locking bar 3.
  • the locking bar 3 remains locked with its contact surfaces 29 in the recess 27 and the torque from the key 5 via the cylinder core 2 ge reaches on thin locking ring 22.
  • the locking ring 22 rotates with the cylinder core until the locking pieces 16 abut the walls 33 of the recess 19 in the housing. The torque is thereby absorbed by the massive locking pieces 16 and the walls 33.
  • balls 33, 34 are also drawn in as further blocking possibilities in order to achieve larger numbers of variations. These balls sit in corresponding holes in the cylinder core and work together with control edges or control surfaces of the key. The balls denoted by 33 are locked by the key into corresponding recesses 35 in the housing, which makes rotation of the cylinder core impossible. The key drawn would therefore be a wrong key. Due to the corresponding recess 35 in the key, the ball 34 can be displaced inwards in the cylinder core, which would allow the cylinder core A to be rotated. With a correct key, all four balls shown in FIG. 2 would have to assume a position as the ball 34 occupies.
  • reference number 36 denotes a control pin which is under spring pressure. At this point it is absolutely necessary to arrange an associated ball in the cylinder core, otherwise the control pin will enter the hole in the cylinder core and catch it.
  • a key retaining pin 37 is provided in FIG. 1, which acts with the associated ball 38 as a ball catch.
  • the lock construction is given a precisely defined central position for the position of the cylinder core.
  • the coupling construction is mounted in axial bores 41 of the two cylinder cores and consists of a coupling device 42 which can be displaced in the axial direction and has contact surfaces 43 on each side and an area with an enlarged diameter 44 each .
  • Cylindrical coupling pieces 46 are slidably mounted in bores 45. The coupling pieces act on the one hand with the run-up surfaces 43 and, on the other hand, engage in a recess 47 of the locking nose ring when the position is shifted. In the position shown in FIG.
  • the key 5 is inserted from the left, through the key tip of which the coupling bolt 42 is displaced to the right.
  • the coupling piece 46 sits on the area with an enlarged diameter 44 and is locked at the top with the locking nose ring 39.
  • the locking nose ring can therefore be rotated together with the cylinder core 2.
  • the right coupling piece 46 is in the expressed position, ie outside the recess 47 of the locking nose ring 39, so that the right cylinder core 40 is disengaged.
  • the coupling device 42 can be made in one piece, so that the two regions 44 with an enlarged diameter always have the same position relative to one another.
  • the coupling device is composed of several parts and is suitable for an emergency closing operation using a special emergency key.
  • the coupling device has a bolt 49, at the ends of which there are two coupling sleeves 50. Between the two coupling sleeves sits a compression spring 51, by means of which the two coupling sleeves are pressed apart into their end position. Furthermore, a spacer sleeve 52 is provided, whereby the two coupling sleeves are supported against lateral pressure and are thus guided.
  • the emergency key function is as follows: In Fig. 1, a normal key is inserted from the left and the coupling construction is shifted to the right, as already described above. An emergency key is now inserted from the right, which has a recess 53 at its tip. In addition to this recess, the emergency key has special elongated recesses for the tumbler pins on the side surfaces (see further below for FIG. 4), as a result of which these tumbler pins are already brought into the unlocked position when the key is not fully inserted.
  • the emergency key is thus inserted from the right and the pin tumblers are unlocked.
  • the cylinder core and the emergency key 54 are rotated under pressure until the coupling piece 46, which lies in the region of this cylinder core, lies opposite the recess 47 of the locking nose ring and enters this recess.
  • This twisting is only necessary when the inserted key 5 is in the twisted position. Otherwise the recess 47 is aligned with the coupling piece 46 in the inserted position of the emergency key.
  • the associated coupling sleeve 50 is displaced inward against the pressure of the spring 51, so that the coupling piece 46 is pushed upward through the run-up surface 43 into the recess 47 of the locking nose ring.
  • the emergency key 54 is thus connected to the locking nose ring 39 for rotation so that the lock can be operated.
  • the two cylinder cores are coupled to one another in a rotationally locking manner.
  • the illustrated locking nose ring 39 engages with claws 100 behind the two turned core ends (turning 101), whereby the two cylinder cores of the double cylinder lock are held together against train.
  • FIG. 3 shows another embodiment of the lock according to the invention according to FIG. 2, the balls 33, 34 being omitted as additional locking elements.
  • the key retaining pin 37 is preferably made of hard metal in order to simultaneously serve as a drill protection.
  • control surfaces 7 for the tumbler pins of the lock are formed by blind holes 55 of different depths.
  • the control surfaces can also be formed in other ways, e.g. through continuous grooves or webs with oblique transitions between the individual control surface levels.
  • blind bores 55 are shown in broken lines (56). If all blind holes are widened in this way, the key can be used as an emergency key, the recess 53, also shown in broken lines, having to be arranged at the top.
  • a corresponding compression spring can also be arranged as a counter-curve for the return movement of the locking bar.
  • the recess 27 in the locking ring 22 has a certain free travel for the movement of the run-up surface 29 to both sides. The purpose of this empty path is that the one the key tumblers can be adjusted at rest and that the locking bar is only axially displaced after a defined rotation of the cylinder core, so that the tumbler pins are not disturbed when the key is inserted quickly or when torque is applied to the key.
  • the separating surface between the cylinder core and the locking strips and also the divisions of the tumbler pins can be made completely flat, the accuracy being in the range of a hundredth of a millimeter.
  • This is different from conventional tumbler pins, the divisions of which lie in the curved separating surface between the cylinder core and the cylinder housing and therefore have to be dome-shaped.
  • the completely flat design according to the invention scanning is made practically impossible. If an attempt were made to scan the pin tumblers from the key channel with a spy, they would have to be brought into the correct position to within 1/100 mm, which is practically impossible. All the more so since a large number of such tumbler pins can be provided.
  • the number of pin tumblers can be kept very high in spite of the limited, predetermined dimension of the cylinder core, since they can be dimensioned small as a result of the locking construction without being exposed to destructive forces.
  • the construction according to the invention can advantageously also be combined with magnetic rotors.
  • Such magnetic rotor designs are already known.
  • the key must have a rib at this point.
  • the corresponding ball has a smaller diameter. If the corresponding rib is missing from the key at the relevant point, the ball with the reduced diameter dips too far into the cylinder core and the control pin engages with the pressure of its spring in the bore in the cylinder core, as a result of which the cylinder core is caught.
  • the lock according to the invention is particularly well suited for the development of complicated locking systems.
  • the requirements of the most complex locking plans can also be met.
  • the points of attack of the pin tumblers are indicated in FIGS. 6 and 7 with dashed lines 58.
  • the key shown has further incisions 59 on the narrow sides of the key for additional conventional pin tumblers.
  • the two narrow sides of the key are symmetrical, so that there is a reversible key here.
  • FIG. 8 shows a further preferred embodiment of the key according to FIGS. 5 to 7, the sectional illustration corresponding exactly to FIG. 7 with regard to the locking differences.
  • the course of the grooves 57 is, however, not curved, but curved.
  • the embodiment according to Figure 8 is obtained in an advantageous manner, a particularly smooth transition between the individual control surfaces, whereby with respect to reliability and wear resistance after years of Benefits of using the key are given.
  • a flat key for locks of the type described here is thus provided, with recesses on the key sides for scanning by scanning and locking elements of the castle are provided, which is characterized in that the. are arranged in a row in a row along the central longitudinal axis of the key in a continuous groove, the control surfaces are formed by sections of different depths of the groove.
  • the flat key according to the invention is then characterized in that the transitions between the control surfaces of a groove are curved, so that the depth of the grooves is wave-shaped.
  • FIG. 9 shows the profile system according to the invention on the basis of a cross section through a key.
  • the two envelopes 60, 61 on the side flanks of the key-S run essentially parallel to one another from the key back 62 over the region 63 to approximately the middle of the key height. From then on, the two envelopes run conically towards the key chest 64.
  • the envelopes 60, 61 run symmetrically to the central longitudinal plane 65.
  • the zero profile is zigzag-shaped.
  • This zig-zag design forms approximately V-shaped profiling areas 66 to 70, which can either be filled with key material or designed as grooves.
  • the filled sections of the profiling areas are referred to as ribs and the unfilled sections as grooves.
  • the profiling regions 67 to 70 have cross sections which are essentially congruent to one another, and within the Cross-section of each of these grooves two ribs or two grooves can be accommodated .. Sotrichliert in Fig. 9 in the grooves 67, 69 and 70 each have a rib, which are referred to as basic profile ribs A, B and C. The arrangement of these basic profile ribs is only one example: Within a locking system, the basic profile ribs always remain in the same place. The remaining sections of the profiling areas 66 to 70 can be designed either as ribs or as grooves to create the necessary variations for superordinate and subordinate keys. These variation elements are designated with the letters o, p, q, r, s, t.
  • the profiling area 66 offers space only for a profile element, which is either present as a rib when this area is completely filled or as a groove.

  • the remaining groove in this area 69 then has a larger cross-sectional area than the rib (here basic profile rib A).
  • the profiling area 69 is provided with two ribs, then this area 69 is completely filled up to the envelope 60.
  • profile sections protrude up to the envelopes 60 and 61. If the profiling areas 66 to 70 are designed as grooves, these sections remain stand as ribs on the key side surfaces.

  • the key corresponds to FIG. 15, which is the superordinate general key (master key).

  • profile elements of the basic profile and of the variable profile are arranged in a column 86, 87 (FIGS. 16 to 19).
  • a superordinate key is relatively simple (few ribs and Grooves) and a subordinate key relatively complicated (many ribs and grooves).
  • a superordinate key (general key) is relatively complicated (many ribs and grooves) and a subordinate key is relatively simple (few ribs and grooves).
  • the master key (master key) is the most complex key, see Fig. 16 or 17 and the subordinate key, Fig. 19 is the simplest.
  • the basic profile can be arranged anywhere. It is essential to the invention that the two types of profile are arranged distributed over the entire effective key area, and these profiles can be connected to one another in any order without the basic profile being only in the immediate vicinity of the key spine.
  • the invention shows that the profile ribs of the basic profile, which generally remain in the cylinder core, can be arranged in such a way that it is difficult to scan the pin tumblers.
  • the cylinder housing is designated 135, 136 is the cylinder core.
  • the core 136 can only be rotated relative to the housing 135 in a known manner if the recessed 117 has brought the tumbler pins 118 into such a position by the inserted correct key 111 that the division points 121 in the separating surface 145 between the housing 135 and the Core 136 lie.
  • each profile element comprises a profile sink 114 and a profile tip 115, both parts are connected by an intermediate part, not shown. All of these profile elements have an essentially rhombic shape.
  • profile parts 114 are provided in the area of the key center plane 113, which extend beyond the key center plane 113 and are arranged so that they overlap, reference numeral 146.
  • This profile further comprises profile elements 114, 115 with different divisions, that is to say with different distances from profile depression 114 to profile tip 115.
  • the envelope 116 of the profile is conical in cross section.
  • the key profile 111 may have recesses 117 (FIG. 21) which interact with tumbler pins 118. Furthermore, it can be seen from FIG. 23 that the distances 123, 124, 125 in the upper region of the key 111 in the vicinity of the key back 126 of adjoining profile elements 114, 115 are provided in a decreasing manner, whereas in the lower region and in the middle region all these distances 125, 127, 128, 129, 130 are kept the same. Finally it can also be seen that, starting from the back of the key 126, the profile is provided to taper conically towards the lower end 131 of the key. As already mentioned, according to the invention, all of the above-mentioned objects are achieved by all of these profile determination pieces.
  • FIG. 24 to 27 serve to explain an exemplary embodiment in which the key has recesses 117 (FIG. 21) which interact with the tumbler pins.
  • FIG. 24 corresponds to point 137 in FIG. 23, but without overlap 146.
  • the tip 147 is under pressure from the spring 120 against the material 148 (delimitation of the recess 117) of the key 111.
  • the tumbler pin 118 is, as drawn with full lines, for an actuation this key in the correct position.
  • the division point 121 between the tumbler pins and the separating surface 145 between the cylinder housing 135 and the cylinder core 136 then coincide.
  • FIG. 25 An overlap 146 according to the invention is shown in FIG. 25 below. Compared to the tip 147 of the tumbler pin 118 there is now no material from the key 111 due to the overlap. The tumbler pin 118 would therefore be pushed into the position shown in dashed lines under the action of its spring 120. Only in this position is the tip 147 of the tumbler pin 118 on the material 148 at 149. The tumbler pin 118 is then shifted too far by the distance 150 and the lock cannot be actuated since the dividing point 121 and separating surface 145 no longer coincide or are no longer sufficiently close to one another.
  • the invention is not restricted to the exemplary embodiment shown.
  • the end of the tumbler pins which cooperates with the recesses 117 can also be provided in a trapezoidal shape.
  • the various profile determination pieces have element protection.
  • the invention thus also includes each such profile determining piece a), b), c) or d) each individually.
  • the various divisions can of course be adapted to the respective conditions and do not have to be dimensioned as determined by FIG. 23.
  • the invention comprises not only the keys described and illustrated, but also the locks belonging to these keys, thus always the entire profile system according to the invention.
