Definitions

  • the invention relates to a locking device consisting of a key and lock.
  • Locks of various types are known, the tumblers of which can be actuated by means of an appropriately designed key and brought into the release position.
  • the key shaft has various elevations and depressions or a correspondingly designed key bit, which acts on the tumblers. If the key is lost and no replacement key is available or can be produced, the lock is worthless and must be replaced with another one.
  • different locks are arranged on the different doors to be locked etc., which requires a large number of keys.
  • Keyless locks so-called permutation locks, are also known, in which the respective key secret can be set as a sequence of numbers by twisting. If the key secret is known, the lock can be opened.
  • the object of the invention is to provide a locking device consisting of a key and lock, which can be used anywhere, so that the authorized user only needs a single key for all locks, it being ensured that only the authorized person is able to to open the locks to be opened, but on the other hand it should also be ensured that another user, with the consent of the authorized person, can open the locks or certain locks without being able to research and recognize the entire key secret.
  • the locking device should be compact and should be easy to manufacture, especially in large series. The dimensions should be such that existing locking devices, for example the cylinder locks used on doors, can be exchanged and converted without difficulty.
  • the locking device should also be readily usable, for example, in motor vehicles, be it as an ignition lock, door lock, trunk lock, etc., so that the authorized person gets by with a single key.
  • the locking device thus consists of a lock with at least two locking or locking elements which cooperate with cams of a shaft arranged in the lock.
  • the locking elements can be piston-like or cassette-like and can be arranged within shafts of the lock body, wherein they are slidably displaceable within the shafts in the unlocked state and locked within the shafts in the locked or blocked state.
  • the locking elements lock within the respective shaft in a radially inner position, in which they abut approximately on the shaft in the region of the cam base, so that the cam is locked in a non-rotatable manner.
  • the locking elements can also be locked within the respective shaft in a radially outer position, in which they are so far outside that the cams of the shaft can slide past them, so that the shaft can thus be rotated. Rotation of the shaft is also achieved when the locking elements are unlocked, the cams pressing the unlocked locking elements outwards when the shaft is rotated.
  • a specific key secret is assigned to each blocking element.
  • the shaft carries two diametrically opposed cams and two diametrically opposed locking elements are provided within the lock body, two key secrets must be observed. These key secrets that are permanently set within the lock, but can be changed if necessary, can now be set on the key, i.e. the identically formed keys are only adapted to the key secrets of the lock known to them by the authorized user.
  • stepped locking pins arranged which engage under the action of springs in the locked position in holes in the lock body and prevent displacement of the locking elements.
  • Corresponding plungers or counter pins interacting with the locking pins are provided for the key, the effective length of which can be adjusted in accordance with the length of the locking pins - the differently graduated lengths of all locking pins result in the key secret of the respective locking element - whereby the required key secret on the key is obtained.
  • a rotatable shaft comes into a rotationally fixed connection with the cam-bearing shaft of the lock, the counter pins of the key press - correctly set - the locking pins of the locking elements into the release position, so that the key shaft and thus the lock shaft can now be rotated.
  • the actual locking element is arranged on the lock shaft, which, for example, cooperates with the latch of the lock and, when the lock shaft is rotated, shifts the latch from the blocking position into the release position.
  • length-matched supplementary pins are assigned to the locking pins.
  • the locking pins are slidably mounted within the lock body.
  • the locking elements are designed as pivotally mounted locking or locking plates within the lock body, which are equipped with blocking approaches. These locking lugs cooperate with the locking pins, the locking pins having a passage opening into which the locking lugs of the locking plates enter when the locking pins are moved into the unlocking position by the plunger of the key. This allows the locking plates to be pivoted outwards into the unlocking position, in which the lock shaft with the cams can be freely rotated.
  • the locking device according to the invention can be used wherever conventional locking devices are attached.
  • the dimensions of the closing body or closing core are chosen so that the closing device can simply be used instead of the conventional devices.
  • All locks only require a single standard key, which can be bought at petrol stations, for example, and can then be adapted to the locks by the user by setting the key secrets.
  • the key is only slightly larger than a normal motor vehicle key; in a preferred embodiment of the invention, it is adjustable one hundred million times.
  • the key secret is set in a few seconds, even in complete darkness, because the number of necessary adjustment steps can be checked by means of a ratchet sound.
  • the fact that the lock has at least two key secrets that are independent of one another makes it possible, for example, to give a car to a friend who only knows one key secret while the other key secret remains unknown to him. After returning the key and unlocking the locking element previously set in the outer blocking position, the unauthorized user can no longer open the lock.
  • the invention is also advantageous to use in offices or workshops, in which employees etc. can open or close the locks according to the invention attached there during working hours, but after the working hours the boss locks and nobody but himself can then open again. Even with electronic devices, the key secrets cannot be intercepted or felt.
  • the lock itself is safe from drilling.
  • the code setting of the lock can be changed by any specialist, but also by technically talented laypersons.
  • the production costs, especially in large series are relatively low and in no way higher than with conventional locking systems.
  • the locking device consists of the actual lock and the associated key, which can be adapted to the lock. 1 and 2, the lock is shown in the locked state.
  • the structural design of the castle is also clear from Fig. 8.
  • the lock body 6 is cylindrical, the dimensions being such that the lock can be exchanged for a conventional cylinder lock without difficulty.
  • a shaft 1 is provided in a central arrangement, one end 2 of which is designed, for example, as a hexagon, while at the other end the closing element 3, which acts, for example, on the lock latch, which is not shown, is rotationally fixed is arranged.
  • On the lock shaft 1 diametrically opposite two cams 4 and 5 are arranged, as can also be clearly seen in Fig. 2.
  • two shafts 7 and 8 are recessed in the lock body, in which the two locking or locking elements 9 and 10 are fitted.
  • the two shafts 7 and 8 run in the radial direction and thus form a single continuous shaft which is traversed by the lock shaft 1.
  • the locking elements 9, 10 are - in accordance with the cross-sectional shape of the shafts 7, 8 - designed as pistons or cassettes and contain a plurality - in the present case four - of adjacent locking pins 11, to which compression springs 12 are assigned in a coaxial arrangement, which strive to provide the locking pins 11 to press and hold in bores 13 of the lock body 6, in which the locking elements 9 and 10 are locked in a radially inner position, as shown in FIGS. 1 and 2. In this blocking position, rotation of the lock shaft 1 is not possible because the two cams 4 and 5 are held clamped between the locking elements 9, 10.
  • the length of the locking pins 11 is different. That is, the lengths of two adjacent locking pins 11 of a locking pin row can be different from one another, a total of ten locking pins 11 being available which have ten different lengths in a stepped manner (cf. also FIG. 9).
  • the decisive factor here is the length with which the locking pins 11 project from the shaft 7 or 8 into the bores 13 of the lock body 6 (in FIG. 9, the dividing line between the shafts 7, 8 and the mouths of the bores 13 with the reference symbol Designated 26).
  • the shortest length can be 0.3 mm (in FIG.
  • each locking element 9 and 10 is thus determined by the number of locking pins - here four - each with a different length. Each row of locking pins thus represents a four-digit key secret, whereby each digit can be changed 10 times. Since the key secrets for each locking element 9 or 10 can be set independently of one another by inserting the correspondingly graduated locking pins 11, the key secrets are therefore changed hundreds of millions of times.
  • Each locking pin 11 is assigned a supplementary pin 27 which is arranged within the bores 13.
  • These bores 13 initially have a larger diameter when viewed from the shafts 7, 8, which corresponds to the diameter of the part of the locking pins 11 entering them, while the diameter decreases towards the outside.
  • the supplementary pins 27 are also reduced in diameter on the outward-facing side.
  • the length of the thickened part of the supplementary pins 27 is matched to the length of the thickened part of the associated locking pin 11, such that the sum of the lengths of the locking and supplementary pins is constant in each case.
  • the supplementary pins 27 arranged in the bores are flush with the end face 28 of the lock body 6.
  • the locking elements 9 and 10 are unlocked with a specially designed socket wrench, as shown in FIGS. 5 to 7.
  • the key 17 consists essentially of a pin 15 rotatably mounted in the key body 14, the projecting end 16 of which is designed in accordance with the shaft end 2 of the lock shaft 1, so that after the key 17 has been inserted, a rotationally fixed coupling between the pin 15 and the lock shaft 1 is produced.
  • a handle 18 is rotatably connected thereto.
  • each setting wheels 19 are rotatably supported on each side, which have projections or teeth 20 distributed over the circumference and carry a helically shaped support surface 21.
  • the plunger or counter pins 22 consist of an inner plunger 29, the free end of which rests on the spiral surface or screw 21, and the outer plunger 30, which leads outwards and is connected to the inner plunger 29 via the connecting web 31. Furthermore, each counter pin 22 still has a relatively long guide part 32.
  • the setting wheels 19, which are mounted on the axles 33, are all in a position in which the inner plungers 29 rest on the radially most retracted part of the spiral surface 21, ie the counter pins 22 have the smallest effective one Length and are most retracted into the key body 14;
  • the outer plunger 30 protrudes from the key body by the first of ten steps by 14.
  • recesses 23 are provided in the area of the setting wheels 19, so that the setting wheels 19 are gripped and adjusted with the finger, ie. can be twisted.
  • the thickened end 24 of a spring 25 engages, which acts as a ratchet and allows the setting wheels 19 to be rotated in both directions of rotation.
  • a characteristic ratchet sound which indicates to the user, even in the dark, by how many steps he has adjusted the respective setting wheel and thus has shifted the outer plunger 3o to the outside .
  • the dials 19 have taken different positions, the respective associated outer plunger 30 protruding to different extents from the key body according to the key secret of the one locking element.
  • the key secret of the other locking element 10 is set with the lower four setting wheels 19. After ten different stages can be set, there are also 10 teeth 20 distributed over the circumference and a corresponding number of tooth gaps into which the thickened end 24 of the ratchet spring 25 falls.
  • a nose 34 is also arranged.
  • this nose 34 is passed through a corresponding recess 35 (see FIG. 10) and engages in a circumferential groove 36 (also in FIG. 1) recognize), so that the key 17 is held firmly on the lock after plugging onto the lock and twisting.
  • each locking element 9 and 10 has a plurality of adjacent locking pins 11, which are of different lengths to form the key secret.
  • Each of these locking pins 11 is now assigned an identically designed retaining pin 37, which is also under the action of a compression spring 38 which tends to press the retaining pin 37 toward the bores 13.
  • the holding pins 37 are also next to each other in a row, this row of holding pins 37 being displaced radially inwards or closer to the axis or lock shaft 1.
  • Each locking element 9 and 10 thus has locking pins 11 and retaining pins 37 in a paired arrangement, each pair each having identical pins.
  • the authorized user who knows the key secret of the two locking elements 9 and 10, sets these key secrets by turning the setting wheels 19 on the key 17 accordingly.
  • the key 17 is attached to the lock, more precisely, when the projecting end 16 of the key pin 15 is attached to the end 2 of the lock shaft 1, the outer plunger 30 penetrate into the bores 13 of the lock body 6, in each case exactly so far that the Supplementary pins 27 and thus the locking pins 11 are displaced counter to the action of the compression springs 12 in such a way that the free end of the locking pins 11 is flush with the dividing line 26, that is to say with the wall of the shaft 7 and 8. In this position Both the locking element 9 and the locking element 10 are unlocked, so that the two locking elements 9 and 10 are freely displaceable in the shafts 7 and 8.
  • the key shaft 15 can thus be rotated via the handle 18 because the lock shaft 1 is unlocked.
  • the two cams 4 and 5 push the locking elements 9, 10 radially outward, so that they reach the position shown in FIGS. 3 and 4.
  • the closing element 3 is also taken, which acts on the actual locking mechanism.
  • the key secret of locking element 9 is still needed to open the lock. A stranger commissioned by the authorized user can therefore only do so recognize a key secret, but not the key secret of the locked locking element. If the key secret of the locked locking element on the key is now set again, the locking element can be moved freely again and slides back into its inner position, where it is locked again after the key has been removed.
  • the lock is compact and due to its dimensions - in Fig. 10 the lock is shown approximately in natural size - easily interchangeable with a cylinder lock of a conventional type. It should also be noted with regard to FIG. 8 that a closure disk 39 is attached after the individual parts of the lock have been assembled.
  • the displacement of the locking elements 9, 10 in the unlocked state is effected by springs 4o, which are fastened to the lock body 6 by screws 41 and the free end of which rests on the locking elements 9, 10.
  • These springs 40 are designed as leaf springs.
  • Small stepping motors can also be provided, for example, for actuating the setting wheels 19 on the key 17. It can also be operated by means of a time relay at the push of a button, if necessary also digitally.
  • FIGS. 11 and 12 Another embodiment is shown in FIGS. 11 and 12, in each of which only one half of the lock body 6 is shown; the other half is largely a mirror image of the half shown.
  • a plurality of locking units 42 are arranged next to one another, that is to say in a row perpendicular to the plane of the drawing, each in a one-piece design with a locking pin and one Summarize the holding pin.
  • the locking units 42 are approximately cuboid, ie they have a rectangular cross section. One side is roughly fork-shaped.
  • the lock body 6 consists of two fork projections 43 and 44, which represent the locking pin 11 (better locking part) and the holding pin 37 (better holding part).
  • a centering pin 45 On the other side of the locking unit 42 protrudes a centering pin 45, which is used to center a compression spring 46, which strives to push the associated locking unit 42 out of the locking element 9 or to push it outwards.

Since only a single spring 46 is required for each locking unit 42, this spring 46 can have a relatively large diameter, so that large spring forces are also available, which lock the locking units 42 with certainty in the locking bore 13 or in the retaining bore 47.
