Description

Cylinder core is blocked. If the correct key is intended to be a rib at such a point bear, no ball may be contained in the associated bore 11 at this point.

To further increase the unlocking security, the ball 14 is arranged in a bore 11, which, however The cylinder core can only be rotated if the key has a Has rib 8 and not a recess 9 as in

(e.g. DE-OS 29 05 941). Has on the relevant recess (groove) 12 in the axial direction. Construction elements and their mode of operation are Weist a wrong key at a point where one is therefore only briefly discussed in the following. In the cylinder housing 1, if a cylinder core 2 is rotatable rib 8, the corresponding ball 10 abuts, which has a keyway 3, into which a 5 the run-up surface 37 and a further rotation of the key 4 is fully inserted. The key channel is arranged centrally in the cylinder core, ie that
also the upper long edge 5 of the key (with
conventional keys of the key return) from
Material of the cylinder core is enclosed, and not ok

completes (see Flg. 5). The key 4 has four
continuous magnetic pills 25 on which to both
Pages can be magnetized differently. In the cylinder core 2, balls 10 are arranged parallel to the magnetic pills of the key 15. The action of the ball 14 results from magnet rotors 26, which, depending on the magnet, in cooperation with the same rotational plane of the key pill, a certain rotational position arranged multi-part key holder pin 17 and take. In a known manner, the circumferential annular groove 15 in the housing 1 is correct. On the side facing the housing In a known catfish, the shell retaining pin 18 carries the axial locking strip 30 locking pieces 3i, which engage in an axial groove 32 of the cylinder housing through the depth of the recess 16 of the key. The division is held so that the core pin lies opposite the most inner locking piece 31 can be moved in a housing pin. Through the irich recess 33 of a locking ring 34, the outside around 25 terförmlge formation (funnel 38) of the housing pin around the cylinder core 2 and free against it 18 is given a certain locking effect, by which the can be rotated. The position of the locking ring with respect to the cylinder core with respect to the housing is a defined central position of the housing 1 by means of a ball catch 35. Fixed when turning the cylinder core. In Fig. 1, the parts 30, 31, 34 are phantom-like running the lower of the two balls 21 in the annular groove in the central section. 30 15 as well as the ball 14, which is held in position by the rib 8 when the cylinder core 2 is held with the key 4. After a rotation of the twisted, the innermost locking piece 31 runs on a key 4 by 180 °, the ball 14 comes to the sloping flank of the recess 33 of the locking ring 34 häusestlft 18 and slides over this, with the open and the axial locking bar to the left The locking effect caused by the funnel 38 can be neglected. As a result, all locking pieces 31 get into a 35 can. The cylinder core can thus be rotated further and such an axial position that it can be carried out with annular grooves 50 on the locking or unlocking process. The inner surface of the housing is aligned and when rotated, however, instead of the rib 8, the cylinder core is falsely guided. In these grooves, a recess 9, as swirled da-geste! U, so the rotation by 180 ° by tion, whereby the axial locking bar can not be moved to the left 40, the housing pin 18 under the pressure of the spring 19, the innermost locking piece remains pushed inwards, whereby the funnel-shaped 31 with the recess 33 of the locking ring in engagement
and when force is applied, the holding force of the ball catch 35 is overcome. The cylinder core can then be turned around

and thus locking the locking device is in
further consequence impossible.

In the cylinder core 2 are carried along the longitudinal edges of the 50 mung, the ball 39 is arranged by the spring 41 and key channel bores 11, which are pressed by the housing pin 40 into the recess, where the key channel up to the interface between the cylinder and the housing pin 40 In the bore 11 engages and the housing and cylinder core reach. The Zv lower core is blocked in the bores in relation to the housing. 11 balls 10, 14, 39 are arranged displaceably. When turning the cylinder core with a correct As can be seen in particular in Fig. 3, the 55 key reaches the opposite point of the core bores Il blind bores that allow penetration of the jacket In the form of a tongue 20 to the ball 39 (see balls 10 In allow the key channel only so far, Fig. 4, arrow S1). The tongue 20 is designed so that, as required for the release position of the Kugeirr, the housing pin 40 is on the surface of the cylinder. The key 4 has on its longitudinal edges 5, 6 core slides and nid «In the slot 28 for the copper to the direction of insertion 7 lying ribs 8 and plungelemenl 27 engages. Otherwise the recesses 9 would appear. Each ball 10 is caught by a housing pin in the slot 28 and assigned to a world server recess 9.

The mobility of the balls bar and can engage in a coupling disk 42 connected with a locking lug 29 transversely to the insertion direction 7 of the key. This enables the cylinder housing to have a clutch disc for this purpose with a locking groove 43. That

107 or 106 arrives and blocks the cylinder core 101 with respect to the housing 102 . The balls 111, 112 can be referred to as control balls.

The balls 113 and 114 correspond to the balls 10 in FIG. I and the bevel incision 117 corresponds to the design 9. These balls, which can be calculated as variation balls, must, in contrast to the control balls, disappear when twisting within the lateral surface 118 of the cylinder core. The mobility of the balls in the rest position of the cylinder core is ensured by the axially guided recesses 119 and 120. The In Flg. 8 ball 114 drawn at the bottom left lies opposite the bevel incision is 117 of the key, which enables the ball 114 to evade into the bore 109 when the cylinder core is rotated and to assume the position shown.

The ball 113 shown on the right in Hg. 8 is not opposite any bevel incision on the key and cannot enter the bore when the cylinder core is rotated

In the Flg. 9 and 10, the key 104 according to the invention associated with the construction according to FIG. 8 is shown in cracks assigned to one another. In this embodiment, the Schl'wisel carries magnetic pills 122 and on the In Flg. 9 visible flat side, the longitudinal grooves 123, 124. The key plate 125 is indicated broken off. The longitudinal edges of the key 104 are broken by bevels 126, 127 and 128. The fourth too. In the Flg. 9, 10 longitudinal edge of the key, not shown, is beveled. These bevels 126 to 128 serve as a running surface for the balls 111 to 109 when the key is inserted into the key channel, which reduces wear on these edges compared to sharp edges.

The chamfer incisions 129, 130 are drawn in at points A and B along the bevel 126. There are no chamfer incisions at points C and D. On the other longitudinal edge of the key (bevel 128) are located at points / 1, C, bevel cuts 131 and 132. On the beard side of the key (bevel 127) , for the sake of simplicity, no bevel cuts are drawn. With

133 , a sphere is indicated by a dashed line, which is assigned to the bevel incision 130 . If the key is a correctly coded key, the function of the ball 133 must correspond to the ball 114 in FIG. At the point D, a ball 134 is also indicated by a dashed line, which is opposite the bevel 126 of the key edge as a web. If the key is correctly coded, as I said, the ball must

134 of a control ball according to balls 111 or 112 in FIG. 8 correspond.

The chamfer cuts are made so deep that they extend into the longitudinal groove 123 . This is advantageous in that it avoids the creation of sharp edges along the flat side of the key.

In the F i g. Various key cross-sections are shown in FIGS. 11-14, illustrating essentially all possible variations at points A, B, C and D. 11 corresponds to point C in FIGS. 9 and 10, fl. 12 corresponds to position B. Flg. 13 corresponds to the position A and Flg. 14 of position I). The same variations are of course also possible on the lower edge, the beard side of the key.

Another possible variation is in the Flg. II to 14 given on the upper edge of the key in that the key also has a groove 135 along the narrow side or a groove 136 on the lower narrow side. The grooves 135, 136 must be assigned projections 137 in the core, which is no longer difficult given the intermediate arrangement of the key channel in the cylinder core.

The lock-key system shown can also be carried out without the arrangement of magnetic pills 122 and the associated rotor magnets. In this case, the annular grooves 15 and 50 are not available in the housing. It must therefore with the arrangement of control balls according to the balls 111

Also in the embodiment according to FIGS. 8th to 14 Is one in the arrangement of magnetic pills Variation is possible because ζ. B. with four possible digits (i.e. eight encodable areas) only three these places are provided with coded pills.

In the key according to the invention according to Flg. 8 to 14 there are therefore the following possible variations to disposal:

a) Longitudinal grooves and / or ribs 123, 124

b) the arrangement of longitudinal grooves or ribs on the back of the key and / or on the key base 135, 136, 137

c) arranging or not arranging chamfer incisions at the possible points of the key, with a variation being given both at the individual positions A, B, C or D through different individual or simultaneous arrangement of the chamfer incisions on the four longitudinal edges of the key, as well as through the variation these incisions with the various possible locations A, B, C, D along the key

d) finally there is also the possibility of variation of the magnetic pills used are available on the key.
