Definitions

  • the invention relates to a lock cylinder for an electronic locking system with at least one actuating element and a closing element, which can be coupled together by an electronically acted coupling element rotatably coupled or blocked.
  • Such lock cylinders are manufactured either as a solid cylinder or as a half cylinder.
  • Solid cylinders are actuated with proof of an appropriate authorization both from a door inside and from a door outside, whereas in half cylinders, which are used for example for key switch in conjunction with garage doors, an actuation only from one side is sufficient.
  • an actuator such as a doorknob
  • a closing element so that this closing element can cause the operation of a lock provided in a lock, for example when turning a door knob.
  • actuator and closing element must be decoupled from each other or a movement of the actuating element to be blocked, so that in this case, for example, by turning a doorknob no movement of a bolt can be triggered.
  • An object of the invention is to provide a lock cylinder of the type mentioned above, which is characterized on the one hand by low power consumption and on the other hand at any time in a defined operating condition in which impermissible manipulations are practically impossible.
  • the lever is either stable in the first or in the second pivot position, without that for the maintenance of these stable pivot positions electrical energy is needed.
  • Electrical energy is only required to activate the electromagnet according to the invention, which is intended to move the lever in the first and / or second pivot position.
  • Such a movement can be accomplished by a very short-term activation of the electromagnet, so that only a short current pulse is needed here, which causes only a very low power consumption.
  • the electromagnet can be provided in the end region of the lever arm facing away from the axis of rotation of the lever. Since, in this case, the electromagnet can generate a torque acting on the lever over a comparatively long lever arm, the force to be applied by the electromagnet can be kept relatively low while further saving electrical energy. The force only has to be so great that the force of each acting permanent magnet or spring acting in each case can be overcome in order to be able to move the lever between the two pivoting positions.
  • the solenoid can be operated optionally with different polarity. In this case, then a single solenoid is sufficient to move the lever from both the first to the second and from the second to the first pivot position. Each of the two movements is accomplished with one polarity each.
  • each of two lever arms of the lever is associated with its own electromagnet, wherein the electromagnets can preferably be arranged on the same side of the lever.
  • a first electromagnet is responsible for a movement of the lever from the first pivot position to the second pivot position and a second electromagnet for the movement of the lever from the second pivot position to the first pivot position. It is sufficient if both electromagnets are operable only with one polarity.
  • both solenoids can be operated with mutually equal polarities, since then both solenoids must either attract or repel the lever to produce the desired lever movements.
  • a respective permanent magnet is assigned to each lever arm, wherein the permanent magnets are preferably arranged on the side of the lever opposite the electromagnet.
  • a permanent magnet is provided to hold the lever stable in its first pivot position, whereas the second permanent magnet is adapted to hold the lever stable in its second pivot position.
  • a permanent magnet can also be replaced by a spring, which biases the lever in the respective pivot position.
  • the two lever arms of the lever may be substantially the same length and extend at an angle to each other, wherein preferably the axis of rotation of the lever is arranged at the connection point of the two lever arms.
  • the lock cylinder according to the invention has two actuating elements, one of which is coupled in a rotationally fixed manner to the closing element only in the first pivot position and the other only in the second pivot position of the lever.
  • Each of the actuators can be rotatably connected to one actuating knob.
  • the lever between the two actuators i. extend between an inner and an outer actuating element, wherein the opposite ends of the lever protrude into the inner and the outer actuating member to provide there by corresponding actuation of the lever for a coupling between the respective actuating element and the closing element.
  • the lever itself can be pivotally mounted in the closing element.
  • the lever can be arranged within an actuating knob, wherein a lever arm is connected to an actuating element designed as a coupling pin which rotatably coupled in the first pivot position of the lever, the operating knob with a non-rotatably connected to the closing element actuating shaft, and which in the second pivot position decouples the actuating knob from the actuating shaft.
  • the lever according to the invention is not within the lock cylinder, but rather within an operating knob arranged.
  • the said coupling pin is located in this embodiment within the operating knob and rotatably connected to the closing element actuating shaft extends into the operating knob, so that they can be rotatably coupled there in a suitable manner via the coupling pin with the operating knob.
  • This variant can be used for half cylinders or for solid cylinders, in which a further actuating knob is always coupled to the closing element.
  • a corresponding device is provided both in an inner and in an outer operating knob, an insert in such a solid cylinder is possible, which allows an actuation of the closing element both from the inside and from the outside only if evidence of authorization.
  • the closing element is firmly connected to a rotatable sleeve together with him arranged within an operating knob lever.
  • the actuating knob forms the actuating element according to the invention.
  • a coupling element is rotatably and axially displaceably mounted in the sleeve and movable over a push rod acted upon by the lever between two different positions. In the first position, the coupling element for non-rotatable connection of the closing element with the actuating knob in the sleeve, and in the second position for decoupling between closing element and operating knob is completely outside the sleeve.
  • Such an arrangement can be used in particular in a half-cylinder.
  • the lever may in turn be located within the lock cylinder and be formed as a leaf spring.
  • the end of that lever arm is associated with an electromagnet, having an engagement portion which engages in the first pivot position of the lever for blocking a rotational movement of the closing element in at least one groove of a rotatably connected to the closing element actuating element and which is in the second pivot position out of engagement with said groove.
  • Fig. 1 shows a lateral sectional view of a lock cylinder 10 which has the shape of a commercial profile cylinder.
  • a closing element 14 and two actuating elements 16, 18 are rotatably mounted about an axis of rotation 12.
  • the actuating elements 16, 18 are arranged adjacent to the two end walls of the closing element 14, so that an end face of the actuating element 16 of an end face of the closing element 14 and an end face of the actuating element 18 of the other end face of the closing element 14 are facing.
  • the closing element 14 has in its central region a in the position shown in Fig. 1 downwardly extending locking lug 20, which is suitable in a conventional manner upon rotation of the closure member 14 about the rotation axis 12 for actuating a lock bolt, not shown.
  • a lever 22 with two lever arms 24, 26 rotatably mounted about a perpendicular to the plane and thus also perpendicular to the axis of rotation 12 extending axis.
  • the orientation of this axis changes accordingly upon rotation of the closing element 14.
  • the mutually equal length lever arms 24, 26 extend at an angle to each other, wherein the axis of rotation of the lever 22 at the connection point of the two lever arms 24, 26 and thus in the middle of the closing element 14 is located.
  • the two lever arms 24, 26 are dimensioned so that they extend with their end portions in end-side cavities of the actuating elements 16, 18 in.
  • a pivoting of the lever 22 can be effected via electromagnets 28, 30, wherein the electromagnet 28 is assigned to the lever arm 24 and the electromagnet 30 to the lever arm 26.
  • the lever arm 24 is pulled to its position shown in Fig. 1.
  • the electromagnet 30 is moved in its aligned with the rotation axis 12 pivoting position counterclockwise.
  • the respective electromagnet 28, 30 is immediately deactivated again.
  • two permanent magnets 32, 34 are provided, which are relative to the lever 22, the electromagnets 28, 30 are arranged opposite each other.
  • the permanent magnet 32 is assigned to the lever arm 24 and the permanent magnet 34 to the lever arm 26.
  • the lever 22 In the pivot position shown in Fig. 1, the lever 22 is held by the permanent magnet 34 in a stable position. If, starting from this position, the electromagnet 30 is activated, the current through the electromagnet 30 must be chosen so large that the force acting on the lever arm 26 attraction of the electromagnet 30, the attraction of the permanent magnet 34 overcomes, so that the lever 22 ultimately counterclockwise is pivoted so far until the lever arm 24 bears against the permanent magnet 32 and is held by this in turn in a stable position. In this position, the lever arm 26 is then aligned with the axis of rotation 12. To return from this position to pivot back into the pivot position shown in FIG. 1, the electromagnet 28 must be activated in such a way that the attractive force of the permanent magnet 32 on the lever arm 24 is overcome.
  • FIG. 2 is a lock cylinder 36, which may also have the shape of a commercial profile cylinder, provided with a closing element 38 which analogous to the embodiment of FIG. 1 has a locking lug 40 and which together with the locking lug 40 to a Rotation axis 42 is rotatably mounted in the lock cylinder 36.
  • the closing element 40 is rigidly connected to a rotatable about the axis of rotation 42 together with it shaft 44, which extends into an actuating knob 46 in which the front side is rotatably mounted on one side of the lock cylinder 36.
  • the shaft 44 is rigidly coupled to a perpendicular to the axis of rotation 42 extending disc 48, which is provided along its circumference with a plurality of equidistantly arranged bores whose longitudinal axes extend parallel to the axis of rotation 42.
  • a coupling pin 50 actuating element which axially displaceable is guided in a bearing element 52, wherein the coupling pin 50 extends parallel to the axis of rotation 42 and relative to the bores of the disc 48 aligned with these is arranged.
  • the disc 48 facing away from the front end of the coupling pin 50 is coupled via a spring 54 with a lever arm 26 of a lever 22.
  • the lever 22 also has a further lever arm 24, wherein the lever arms 24, 26 each have an electromagnet 28, 30 and a permanent magnet 32, 34 is assigned.
  • the arrangement of the magnets 28, 30, 32, 34 and the lever 22 corresponds to the arrangement already explained in connection with FIG. 1, with the difference that the lever arm 26 according to FIG. 2 is longer than the lever arm 24.
  • pivotal position of the lever 22 of the coupling pin 50 is displaced by the lever arm 26 in one of the holes of the disc 48, wherein the lever 22 is held by the permanent magnet 34 stably in this position. If the rotationally fixed coupling between the actuating knob 46 and closing element 38 is to be canceled, it is necessary to activate the electromagnet 30 for a short time, so that the lever arm 26 is attracted by this electromagnet 30. As a result, the lever arm 26 moves away from the disc 48 and takes the coupling pin 50 so that it moves out of the respective bore of the disc 48. In this position, the lever 22 is then held stable by the permanent magnet 32.
  • the electromagnet 28 is briefly activated, so that the coupling pin 50 is acted upon by the lever arm 26 in the direction of the disk 48.
  • the spring 54 is compressed, so that the coupling pin abuts the disc 48 under pretension.
  • the lever 22 is already in its pivot position shown in Fig. 2.
  • a closing element 59 rotatable about an axis of rotation 58 is provided which consists of a sleeve 60 and a locking nose 62 fixedly connected thereto.
  • a rotatable actuating knob 64 On one end face of the lock cylinder 56 is coupled to a rotatable actuating knob 64, in which analogous to the embodiment of FIG. 2, a lever 22 is provided with lever arms 24, 26, which is acted upon by electromagnets 28, 30 and permanent magnets 32, 34 can be. The latter components are in turn fixed in a rotationally fixed relative to the housing of the actuating knob 64.
  • the sleeve 60 of the closing element 59 has a central recess whose inner circumferential line deviates from a circular line extending concentrically with the axis of rotation 58.
  • a complementary coupling element 66 axially, but rotatably inserted, wherein the insertion direction extends parallel to the axis of rotation 58.
  • the coupling element 66 is fixedly connected to a push rod 68, which extends from the coupling element 66 into the actuating knob 64 inside.
  • the push rod 68 ends before the lever arm 26, with which it is connected by a spring 70.
  • the push rod 68 can be moved with the coupling element 66 by pivoting the lever 22 into the sleeve 60 or out of the sleeve 60.
  • the coupling element 66 is inside the sleeve 60, there is a positive connection between the coupling element 66 and the closing element 59, so that a rotation of the actuating knob 64 also leads to a rotation of the closing element 59.
  • Such a position is drawn in FIG.
  • lever 22 is pivoted counterclockwise, moves the lever arm 26 via the spring 70, the push rod 68 and thus the coupling element 66 out of the sleeve 60 of the closing element 59, so that the operating knob 64 is freely rotatable relative to the closing element 59.
  • the lever 22 is not drawn to scale in Fig. 3, since for a complete movement of the coupling member 66 from the sleeve 60 out a larger pivoting of the lever arm 26 would be necessary, as illustrated in FIG.
  • a lock cylinder 72 is provided with a closing element 74 with a closing nose 76, wherein the closing element 74 is rotationally fixedly coupled to an actuating knob 80 via a shaft 78.
  • rotation of the operating knob 80 basically results in rotation of the closure member 74.
  • the shaft 78 is provided along its circumference with grooves 86, in which an engagement portion 84 of a two-armed lever 22 ', which is rotatably mounted about a rotation axis 82, can engage.
  • the lever 22 ' is acted upon by a bistable magnet 88 which is fixedly connected to a lever arm of the lever 22'.
