Definitions

  • the invention relates to locking cylinders with a housing and a core rotatable therein and carrying one or more tumblers, in particular magnetic rotors, at least one axially displaceable locking bar is provided in the core, the displaceability of which is controlled by the tumblers and the locking bar has outwardly projecting locking projections, the Has housing arranged on the inner wall longitudinal housing grooves and annular grooves, the annular grooves are arranged in such an axial position that in the displaced position of the locking bar, in which inwardly projecting scanning elements lie in recesses of the tumblers, a release for the outwardly projecting locking projections when twisting of the core is given.
  • the above-mentioned locking cylinders are state of the art and e.g. in AT-PS 357 430.
  • a locking bar is used, which is prestressed from one side by spring force and is pressed against the control surface of a locking ring with a control lug.
  • the effect of the locking ring as a limit force coupling depends on the mechanical accuracy. Relatively high forces are necessary for triggering the limit force coupling, which adversely affect them magnetic rotors work. Incorrect installation can lead to tension and bending of the locking ring, so that it does not retain its exact effect.
  • the object of the present invention is to avoid the above-mentioned disadvantages and to provide a lock construction which meets the high requirements for locking accuracy and operational security.
  • the locking bar has two oppositely directed control lugs, which are guided on opposite control surfaces connected to the cylinder housing in a rotationally fixed manner, thereby giving positive control, one control surface being a concave section and the other Control surface opposite comprises a convex section, and that the control lug assigned to the concave section is resiliently displaceable against the other control lug, whereby after exceeding a limit force, a relative displacement between the control surface and the locking bar and thus a rotation of the cylinder core is possible without axial displacement of the locking bar.
  • the invention is characterized in that the displaceable control lug is resiliently mounted as a control pin in a recess in the locking bar and that - the displacement movement of the control pin to the outside is limited by a stop.
  • the control pin is pivotable about its longitudinal axis, so that the rotational position of the control lug can adapt to the course of the control surface on the concave section.
  • FIG. 1 schematically shows a partial section through a cylinder lock according to the invention, the section lying in the plane of the axes of the magnet rotors, see section line II in FIG. 2.
  • FIG. 2 is a plan view of the locking cylinder according to arrow II in FIG . 1, wherein the cylinder housing is shown broken.
  • FIG. 3 is a view of section line III-III through the locking bar in FIG. 1.
  • the basic structure of the locking cylinder according to the invention is similar to that of AT-PS 357 430.
  • a recess 3 is arranged parallel to the key channel 2, in which the magnetic gates 4 are arranged to rotate freely.
  • the magnet rotors 4 are brought into the position shown in FIG. 1, the recesses 5 of the magnet rotors being aligned such that the scanning elements 6 of a locking bar 22 are axially displaced and can enter the recesses 5.
  • the locking bar according to AT-PS 357 430 is in one piece and has both the function of scanning the position of the rotary tumblers and the function of locking the locking cylinder against rotation.
  • the locking bar 22 shown here comprises a scanning slide 7 and a locking slide 10.
  • the scanning slide 7 lies opposite the rotary tumblers 4 and has scanning elements 6.
  • a driver 8 is provided on the other side of the scanning slide. This driver engages in a recess 9 of the locking slide 10, whereby the two slides are non-positively connected.
  • a core cover 11 is arranged between the two mentioned slides and is inserted tightly in the recess 3 in the core 1. For the movement of the driver 8, the core cover 11 has a slot 12. To seal this slot 12 to the outside, a sealing plate 13 is arranged between the locking slide 10 and the core cover 11, which can be moved with the driver 8 on the core cover 11.
  • the locking slide 10 has on its surface the locking projections 14, which are arranged in a known manner in the 0 position of the locking cylinder in an axial groove 23 of the cylinder housing 24 and can thus be moved axially with the locking slide.
  • the locking slide 10 assumes such an axial position that the locking extensions 14 can be aligned with the associated ring channels 31 of the cylinder core the cylinder core is rotated and the associated lock (not shown here) can be operated.
  • the locking bar or its locking slide 10 has two control lugs 15, 16 directed in opposite directions. These control lugs interact with control surfaces 17, 18 of two control rings 19, 20.
  • the control surface 17 has a convex section 21 and the control surface 18 has a corresponding concave section 26.
  • the control rings 19 and 20 are rotatably connected to the cylinder housing 24.
  • the control ring 19 sits in a recess in the cylinder housing, the shoulder 27 engaging in the axial groove 23 and thus preventing the control ring from rotating relative to the cylinder housing.
  • the control ring 20 is seated in an annular recess in the cylinder core 1 and is preferably made in two parts for assembly reasons.
  • the projection 28 protrudes outwards into the axial groove 23 of the housing in order to prevent the control ring 20 from rotating with the cylinder core 1.
  • control lug 16 assigned to the concave section 26 can be moved resiliently against the other control lug 15.
  • the control lug 16 is designed as a control pin 32 which is slidably mounted in a recess 33 in the locking slide 10. The control lug 16 is pushed outwards by the spring 34, a bolt 35 in cooperation with a locking groove 36 of the control pin giving a stop for the movement of the control lug 16.
  • the locking bar 10 remains in the position shown in FIGS. 1 and 2, i.e. the lock bar is not moved to the right.
  • the width of the axial groove 23 results in a relative displacement between the control rings 19, 20 and the locking bar, the control lug 16 running onto the concave control surface 26 and the control lug 16 being pushed entirely into the step-shaped recess 33 of the locking slide 10.
  • This allows a further relative rotation of the cylinder core until the locking projections 14 strike the stop surfaces 37, which are formed by the axial groove 23 and remain between the annular grooves 31.
  • the further rotation of the cylinder core and actuation of the lock is thus effectively prevented, the forces being absorbed by the relatively large-sized locking extensions 14.
  • the magnet rotors 4 are largely relieved and only have to absorb the pressure force of the spring 34.
  • the control pin 32 By appropriately dimensioning the locking groove 36 and the bolt 33, the control pin 32 has so much play that it can be pivoted about its longitudinal axis by a certain amount.
  • the rotational position of the control nose can thus adapt to the course of the concave control surface.
  • the wear of the control ring 20 is reduced and the manufacture of the control ring is simplified since the concave portion 26 of the control surface can be provided as a simple milling, and the Fräswig does not have to be spherical.
  • the device according to the invention has the advantage that the forces for triggering the limit force clutch can be set precisely since they only depend on the strength of the spring 34.
  • the spring 34 only has to be so strong that it ensures for normal operation that the control lug 16 remains in its outer end position, so that the positive control by the two control surfaces 18, 17 is actually given.
  • the parts of the magnetic rotors and other control parts can be dimensioned weak, since they only have to absorb small forces.
  • the sensitive interior of the locking cylinder is reliably protected against dust, vapors, moisture, etc.
  • control rings are arranged so that the concave portion is inside the lock.
  • the whole arrangement can also be reversed in the lock, so that the displacement of the locking bar takes place in the other direction.
  • the control rings can also be formed in one piece with the housing.
  • the magnet rotor construction is shown in FIG. 1 with the associated locking elements only on one side of the cylinder core. Symmetrically to this, a similar construction can also be arranged on the other side of the lock, as a result of which the number of variations and the blocking forces to be absorbed are increased.
  • the core lid 11 can be made of plastic or metal.
  • the core cover has raised edges 38, 39 on both sides, which effect the guidance in the direction of displacement.
  • the inventive design of the limit force clutch with the two control rings and the two control lugs which are variable in their spacing from one another can also advantageously be used together with other types of guard locking.
  • Wei ters the locking bar can also be provided in one piece, as is known according to AT-PS 357 430.
  • the locking groove 36 of the control pin 32 and the bolt 35 pressed into the locking bar 22 are dimensioned such that the control pin can be pivoted or rotated about its longitudinal axis, so that the rotational position of the associated control nose (reference number 16 in FIGS 1 and 2) can adapt to the shape of the control surface 18 on the concave section 26.
