Definitions
- the invention relates to a locking system in a door, wall, chest, safe, cupboard or the like, which is covered by an outer plate, a locking bolt, gripper or the like, coupled to a main lever rotating about a pivot bearing, with a holding plate , a bar or the like. cooperates.
- the protective function in the private and business sector is first and foremost a personal responsibility and thus self-protection.
- the daily break-ins are increasing alarmingly, despite the well-built and secured house entrance doors, alarm systems or the like.
- the present invention has for its object to significantly improve the security of a locking system.
- the rotation of the main lever depends on the movement of a magnetic block placed on the outer plate, the main lever having at least one hole for receiving at least one locking pin, which is unlocked by pulling out of the hole on the outer plate ⁇ set magnetic block is assigned.
- This locking system can be located anywhere in a door leaf, but the door leaf is completely smooth when viewed from the outside. This makes it extremely difficult for the burglar to determine the position of the locking system.
- the same also applies to the arrangement of this locking system, for example in the wall of a chest, with a corresponding lid being held in the closed position by the locking system.
- the list for which areas or for which furniture this locking system is to be used is only exemplary; the scope of the invention also includes other possible uses.
- An opening or a closing process is triggered by attaching magnetic blocks to the outer plate, these magnetic blocks as magnetic keys perform separate functions. They interact with inner magnetic blocks.
- the inner magnetic block that holds the locking pins can be called the technical heart of the entire system.
- the locking pins are mounted in this magnetic block so that they are pulled out of the holes in the main lever when the outer magnetic block is attached to the outer plate. This happens, for example, in that the locking pin is connected to a pull magnet. The locking pin is then returned to its closed position using an appropriate compression spring.
- the locking pin there is also an indirect possibility of movement for the locking pin by connecting it to a pressure magnet via a rocker arm.
- the rocker arm has a center of rotation approximately in the center, so that when the magnetic block is attached, the locking pin is pulled out of the corresponding bore when the pressure magnet is pushed away.
- these bores should preferably be arranged on circular arc sections around the pivot bearing of the main lever. On these arcs located "are then also the locking pins, so that they can, after a certain Dre ⁇ hung the main lever in the corresponding holes ein ⁇ rest.
- a single locking pin is sufficient.
- the locking pins in the magnetic block there are a variety of possible arrangements for the locking pins in the magnetic block. However, since a locking system with a high number of locks is to be created, a plurality of locking pins are provided in the magnetic block. It is possible both to vary the position of the individual securing pins relative to one another, to alternate with push and pull magnets or to provide dummy magnets. There in the outer magnetic block there must be a congruent number of magnets corresponding in number in order to pull all the safety pins, only one specific magnetic block matched to an arrangement of these safety pins is suitable. This allows the number of locks to be expanded extensively.
- the outer magnetic block is assigned an inner magnetic block on a rotary shaft, the rotational movement of which is transmitted via a rotary shaft to a spur gear, which in turn meshes with a toothed segment or a toothed rack on the main lever. This causes the main lever to pivot.
- a second spur gear can also be provided on the rotary shaft, which cooperates with a second toothed segment or a second toothed rack on a second lever.
- a corresponding abutment can also be assigned to the gripper of the one main lever, however During a closing movement, the gripper first passes through an eyelet in a bolt and then moves into a recess in the abutment. This results in a much better securing of the bolt on the gripper.
- the bolt is indirectly connected to the main lever via a ratchet lever and a connecting lever.
- This embodiment should also be encompassed by the present invention.
- a symmetrical arrangement of two ratchet levers is also possible by means of a second connecting lever.
- the present locking system according to the invention also includes a corresponding magnetic key, which has a special design, especially when the magnetic block is turned.
- a main body carries on one side the outer magnetic block for unlocking the locking pins. On the other side, a hole is formed in it, in which the other outer magnetic block can rotate.
- the main body with the outer magnetic block for unlocking the locking pins is first placed on the outer plate, with its corresponding magnets in the inner magnetic block due to its integrated magnets. finds and so sticks to the outer plate.
- the position of the hole simultaneously provides an indication of the position of the magnetic wheel, so that now only the second outer magnetic block needs to be inserted into the hole, the locking system being unlocked or locked by a rotary movement of this magnetic block .
- an air cushion should remain between this magnetic block and the surface. This is caused by the fact that outer magnetic block, an insert is formed with an annular shoulder, the thickness of the insert being less than the thickness of the main body. The diameter of the insert is slightly smaller than the diameter of the hole.
- This locking system according to the invention can also be used in wooden doors or wooden walls which are never as conspicuous as steel doors or steel safes.

- Fig. 13 shows a cross section through the magnetic key. 11 along line XIII - XIII.
- a locking system R has a lever arrangement which is mounted ready for installation on a carrier plate 3.
- the carrier plate 3 sits in a door leaf 32, its lever arrangement cooperating with a holding plate 14 in a door frame 33.
- a main lever 1 is arranged on the carrier plate 3 and is connected to the carrier plate 3 via a pivot bearing 4. This main lever 1 can rotate about the pivot bearing 4 in the direction a.
- the pivot bearing 4 divides the main lever 1 into an upper lever arm 1 a and a lower lever arm 1 b.
- a magnetic block 18 is provided, the function of which will be described later.
- the connecting lever 11 forms an articulation point 13 with the pawl 35.
- a locking bolt 15 can move into and out of a locking groove 36 in the holding plate 14.
- the holding plate 14 is embedded in a door frame 33, as is not to be shown in more detail.
- the entire carrier plate 3 with the main lever 1 and the pawl 35 is inserted into the door leaf 32 and by one Outer plate 32a is covered. As a result, the locking system R is not visible from the outside.
- An inner magnet block 18 is provided on the upper lever arm la for moving the main lever 1.
- Corresponding pull magnets 19 are arranged in this magnetic block 18. Rotation of the main lever 1 about the rotary bearing 4 is brought about by a magnetic block 25 indicated in FIG. 4, which is placed on the outer plate 32a above the magnetic block 18 and pivoted in the direction a. The main lever 1 then follows this movement. The movement is transmitted via the connecting lever 11 to the pawl 35, which is thus guided either into or out of the closing groove 36.
- FIG. 2 A bearing bush 5 can also be seen in FIG formed as a pivot bolt pivot bearing 4 and which holds the main lever 1 at a desired distance from a second inner magnetic block 2, which also receives the locking pins 6.
- This magnetic block 2 is the "technical heart" of the present locking system R.
- the locking pins 6 are connected to pull magnets 27 which can slide in blind holes 31 in the magnetic block 2.
- the blind hole 31 is pushed onto each locking pin 6 a spring 8 which is supported between the magnet block 2 and an annular collar fixed on the locking pin 6.
- a magnetic block 26 for unlocking is placed on the outer plate 32a, the pulling magnets 27 are thereby attracted and the locking pins 6 move out of the bores 16.
- the Main lever 1 released.
- the magnet block 26 adheres by its magnetic effect on the outer leaf of the door or a corresponding container, so that it need not be further firmly held by the user.
- the user then only has to feel the magnetic block 18 with the other magnetic block 25 and pivot this magnetic block 25 in direction a, so that the main lever 1 can rotate about the rotary bearing 4.
- the opening angle a of the upper lever arm 1 a to the lower lever arm 1 b runs via the pivot bearing 4 and forms the same angle a to a central axis A that is also determining for all intersection points that arise with the radii to the pivot point 4. These radii are also determining for the bores 16 in the main lever 1 and the corresponding recesses for the centering pins 6 in the magnet block 2 and also for the corresponding magnets 27.
- FIG. 5 An embodiment is selected in FIG. 5, in which work is carried out instead of pulling magnets with pushing magnets 20.
- the pressure magnet 20 is articulated via a rocker lever 22 to a locking pin 24, which in turn is closed by a recoil spring 21, i.e. retracted into the bore 16 is held. If the pressure magnet 20 is repelled via the appropriately designed magnetic block 26, it lifts the locking pin 24 out of the bore 16 via the rocker arm 22.
- This configuration offers a further security for the locking system R.
- a recess 24a is indicated in the carrier plate 3 in FIG. 3, by which the rotary movement of the main lever 1 is limited.
- a closed position of the system is shown as a solid line, while an open position of the magnetic block 18 is indicated by dash-dotted lines.
- the locking system works freely on the bearings 4 and 12 (balanced) without any significant friction losses; only the weight of the light metal levers can be moved with the magnetic effect.
- a change in the magnets in the inner magnetic blocks 2 and 18 also always requires a change in the outer magnetic blocks 25 and 26 for the functional fitting with the integrated individual magnets 19 and 27.
- a second connecting lever 11a can also be connected to one second pawl, not shown in detail, this arrangement then being symmetrical.
- the main lever 1A is also designed as a pawl, with a gripper 40 being associated with it. In the locked position, this gripper 40 overlaps a corresponding latch 41.
- the main lever is rotatably arranged about a pivot bearing 4.
- the pivot bearing 4 sits on a carrier plate 3.
- a magnetic block 2a with the corresponding locking pins 6 can be seen.
- a tooth segment 42A is placed on the main lever 1A.
- a toothing 43 of a spur gear 44A which is supported on a rotary shaft 45, engages in the toothing of this toothed segment 42A.
- a further wheel 46 is seated on the rotating shaft 45, into which inner magnets 47 are embedded. If the magnetic block 25 is now placed on the outer plate 32a above the wheel 46 and rotated, the wheel 46 also rotates, so that a magnetic coupling is produced. The rotation of the wheel 46 is transmitted via the rotary shaft 45 to the spur gear 44A, the toothing 43 of which rolls the toothed segment 42A and pivots the lever 1A.
- a second closing lever 1B on which a further toothed segment 42B is placed, is also arranged rotatably on the rotary bearing 4.
- This toothed segment 42B interacts with a further spur gear 44B in the same way as the spur gear 44A with the toothed segment 42A.
- This spur gear 44B is also arranged on the same rotary shaft 45.
- An opening movement of the levers 1A and 1B is otherwise limited by a slide shoe 48, which forms a stop shoulder 49.
- this locking system R2 is not inserted into a door but into a chest, the outer plate 32a forming a front wall of this chest.
- This front wall is overlapped by a cover 50, on which the bolt 41 is also fixed by means of a fastening bracket 51.
- the main lever 1 is assigned a hook-shaped gripper 40 which interacts with an abutment 53.
- the gripper 40 passes through an eyelet 54 in the bolt 41a and engages in a recess 55 in the abutment 53.
- the gripper 40 is secured in a particularly good manner on train.
- the latch 41a cannot slide off the gripper 40.
- the abutment 53 can also have a notch 56, indicated by dashed lines, into the lever, into which the main lever 1 is inserted and guided when it is closed. Furthermore, there is a further locking pin 57 at the end of the main lever 1A opposite the gripper 40 To be determined, which engages in a corresponding locking trough 58 in a counter bearing 59 in the closed position.
- a magnetic key M according to the invention.
- Figures 11-13 can be made of wood, plastic or a metal.
- This magnetic key M essentially has a main body 60 which carries the magnetic block 26 at one end.
- a hole 61 is formed in the main body 60, into which the magnetic block 25 can be inserted, this magnetic block 25 rotating in the hole 61 and transmitting its rotary movement to the wheel 46.
- This magnetic key is particularly suitable for the embodiment of the locking system R2 and R3.
- the magnetic block 25 essentially consists of a rotary housing 62, in which a four-pole rotary magnet 63 is inserted.
- the rotary housing 62 forms a circular insert 65 with the formation of an annular shoulder 64, the diameter d of which is somewhat smaller than the diameter d1 of the hole 61.
- the thickness e is somewhat less than the thickness f of the main body 60, so that after the magnetic block 25 has been inserted, the lower surface of the insert 65 encloses an air gap 66 with, for example, the surface of the outer plate 32a. This ensures that the surface of the outer plate 32a is not damaged when the magnetic block is rotated, so that it is also not possible to see at which point the magnetic block 25 has to be applied in order to rotate the wheel 44. This is particularly important when using the locking system in security products such as safes, cupboards, safes, security doors or the like.
- a plurality of magnets 67 and also dummy magnets can be used in the magnetic block 26, the interaction also also relating to the system
