^w Cylinder lock with permanent magnet "15p 33 6 4

Lock cylinders for furniture, shop fittings, building locks, Motor vehicles, safes, containers or detachable connections of all kinds, in which the locking or unlocking by means of several permanent magnets built into the lock cylinder takes place in connection with other permanent magnets located in the key, where the permanent magnet · according to the number and shape of poles are matched.

2.) State of the art

Reference is made to our own patent application H 56 738 Ic / 68a taken. This is limited to lock cylinders with permanent magnets. There is therefore no need to rely on the already known embodiments of locks, locks, etc., with magnetic locking or on the use of electromagnets to enter into such locking systems. These do not affect the present invention.

As far as locking cylinders with permanent magnets have already been proposed, it is a matter of transferring the ratios with normal mechanical lock cylinders with replacement of the steel pins with pins made of permanent magnets. With these is the inner cylinder is in one position with the cylinder housing coupled, i.e. not rotatable. These in the following property rights

The embodiments described make the inventive step spoiled, which is possible through the use of permanent magnets. The state of the art remains characterized primarily by the last mentioned © DBGM 1 916 23 ^ f ₉ in which, analogous to the sea-hariisoll ScJiließjäylinder locking pin © as a permanent magnet, under spring pressure, the inner cylinder is coupled to the cylinder housing, diösa locking pins by importing an appropriately polarized one Keys provided with permanent magnets are pressed outwards and thereby make the locking cylinder freely rotatable so that the locking process can be carried out.

The disadvantage is that these locking pins must be held as permanent magnets with springs or additional permanent magnets. In the locked state, they are subjected to shearing stress when using force. Besides, they only leave a small one Number of locks and therefore only provide a low level of security. Such lock cylinders offer little protection against twisting of the inner cylinder through the use of force.

The outer cylinder (5 (contains:

The inner cylinder (2) with the two ring magnets (3) (the second ring magnet on the back is not shown), which are rotatably mounted independently of one another, the coupling element (^, 8,9,1O) and the driver (6).

The intermediate cylinder (l6) with the recesses (2O) ₍ the inner cylinder (12) with the magnetic canoes (2l), in which the magnetic bodies (13) are located (the second magnet on the back is not shown) are located in the outer cylinder (15). are axially freely displaceable and the detent slide (lk) as a coupling element between the inner cylinder (l2) and the intermediate cylinder (l6).

Functional explanation The inner cylinder (12) accommodates the key * organ (ll). The freely displaceable magnetic bodies (13) are each provided with a magnetron which is at a certain distance from a groove (17) located in the magnetic body (13). The key organ (ll), which is also equipped with a magnetic body, is magnetized in such a way that the magnetic zones of the key organ (ll) coincide with the magnetic zones of the magnetic body (13). When the key organ (ll) is inserted into the inner cylinder (12), the magnetic bodies (13) move exactly over the magnetic zones of the key organ (ll), so that the groove (17) is aligned with the catch (l8) and the spring (19) the locking slide (lk) engages in the recess (20) of the intermediate cylinder (l6). Now there is a force-fit connection between the key organ (II) and the intermediate cylinder (16), so that force can be transmitted.

When the key member (ll) is withdrawn, the latching slide (14) is lifted into the rest position via a latching curve (22) of the keying member (ll), so that the connection between the latching slide (lk) and the intermediate cylinder (16) is released. At the same time, the magnetic bodies (13) are released and adjusted by being carried along by the key organ (ll) through the magnetic adhesive force in the end division within the magnet chamber (2l). The locking adhesive (lk) sits on the magnet body (13) by means of the tensioned spring (I9) next to the grooves (17) and blocks them. The coupling between Rastechiober (lk) and

Intermediate cylinder (l6) remains released and the inner cylinder (12) cd lets you turn empty.

Fig «5

The coupling rings (A, B, C, D) are located in the outer cylinder (27) with the coupling magnet (25), the hollow shaft (24) and driver (28).

Functional explanation: The hollow shaft (24) accommodates the key element (23). The power is transmitted from the key organ (23) directly onto the coupling ring (A). The magnetic bodies (26) located in the key organ (23) collide with the correct polarity Coupling magnets (25) so that they move radially into the recesses (29) of the adjacent coupling flange. In this way the power is transmitted from the coupling ring (A) to the coupling ring (b) and from the coupling ring (b) to Coupling ring (C), from coupling ring (c) to coupling ring (d) and then to driver (28).

When pulling out the key organ (23) the coupling magnets (25) of each coupling ring (A ₁ B, C, D) attract each other and loosen all couplings, the hollow shaft (24) can be rotated empty. If an incorrectly polarized key organ (13) (see Fig. 5) is introduced, one or more coupling magnets (25) are not repelled but rather attracted, so that coupling with the next coupling flange cannot take place. Thus, the positive connection between the key member (23) and the driver (28) remains interrupted, so that the key member (23) of the hollow shaft (2k) can be rotated empty.

Fig. 6

The coupling rings (E, F, G, H, l] are located in the outer cylinder (34) with the coupling magnet (32), the hollow shaft (31) and the Driver (35).

Functional explanation The hollow shaft (31) accommodates the key element (30). The power is transmitted from the key element (30) directly to the coupling ring (E). The magnet bodies (33) in the key organ (30) are polarized so that they attract the coupling magnets (32) and take them along in the axial direction, so that they fit into the recesses of the coupling rings co (F ₁ G ₁ H ₁ I ,) and engage in the driver (35). Now a to power transmission can take place from the key member (30) to the driver (35) ^, since the coupling rings (Β-!) And driver (35) are coupled together. When pulling out the key

Key organ (30), one or more coupling magnets (32) are not taken along, so that there is no coupling with the next coupling ring at this point. Hence the connection between kraftschilissige key member (30) and follower (35) is interrupted at one or more points, so _a to d ß the key member (30) of the hollow shaft (3l) can rotate empty.

Coupling ring I, functional explanationί In contrast to the coupling rings (F, G, H) and drivers (35), the coupling ring (l) has no magnets. The coupling ring (i) can be inserted at any point between the coupling rings (Eu. F) or (Fu. G) or (Gu. H) or, as shown in the figure, between the coupling ring (H) and the driver (35). The coupling ring (1) reverses the direction of the movement of the coupling magnets (32). In the figure, the coupling magnets (32) move from the coupling ring (H) to the right into the coupling ring (i) and the coupling magnets (3 £,) ^from the driver (35) to the left into the coupling ring (l).

In the outer cylinder (4θ) are: The inner cylinder (37) as Hollow shaft for receiving "the key organ (3 ^)" on the circumference circumferential grooves (46), the locking magnet © (38), a compression spring (44) and the driver (4l).

Functional explanation s In the idle state, the inner cylinder (37) can be rotated empty. In the outer cylinder (4θ) in the chambers (45) are the locking magnets (38), which attract each other and slide up to about half their length into the circumferential grooves (46) of the inner cylinder (3)), so that the inner cylinder (37) is locked against axial displacement.

polarized key organ (36) are one or more blocking magnets (38) not repelled but attracted, so that the inner cylinder (37) remains locked against axial displacement. The inner cylinder (37) can be rotated empty, a coupling cannot take place.

k. ) Advantages over the prior art The lock cylinder according to the invention allows all possibilities to be exploited through the use of permanent magnets, namely through the use of magnetic ring bodies or sliding magnets. This results in a large number of locking devices and a high level of security from the large number of possible pole arrangements or zones. The inner cylinder can always be rotated. This means that any use of force with the wrong key or other tool is useless. The coupling of the Innenzylindex M with the outer cylinder or housing only takes place after the associated key has been inserted. This results in increased safety, no shearing off of the coupling elements. The small number of individual parts and the simple assembly enable economical mass and series production, although this lock cylinder offers significant advantages.
