Description

The invention relates to a locking cylinder in the preamble of claims 1 and 22 Art.

The use of electronics for actuating locking cylinders results in special Problems with the independence of the mode of operation by inserting a own electrical source and reaching an extremely reduced Size so that everything can be accommodated in the small space that is in the flat vertical approach of a lock cylinder with a European profile (that of the Shape of a pear reminiscent) is available. This European profile has one widespread and represents the worst case of a kind of the farthest widespread locking cylinders because the available space is the smallest.

The energy consumption results largely from the actuation of the electromechanical Device for blocking or locking the rotation. ever the lower the friction in this locking device, the lower the electrical energy consumption and thus the independence of the mode of operation.

In this regard, there are several electromechanical locking devices the rotational movement is known in which the locking is achieved with the help of a part that is vertical in the radial direction to the cylindrical rotatable member is displaceable, the rotation of which is to be blocked.

DE-A-195 19 789 discloses a locking cylinder with an electromechanical one Rotary lock known that a double-body stator housing for actuating the Lock cylinder from the outside and inside of the lock and has respective outer and / or inner rotors, which are located inside the body of the Rotate the stator housing and one channel each for the insertion of the shaft one have corresponding electronic key that with an interactive is provided electronic circuit that is electronically encodable. A vertical Retractable latch is in the radial direction opposite the outer rotor movable and forms part of an electromechanical locking device the rotation of the outer rotor that forms electrically with an electronic Processor unit is connected, which has a micromotor for driving the bolt in the Lock position and controls from this.

In such devices, it is also known the positions of the vertical sliding bolt for locking or releasing the rotary movement a rotor directly over a right-angled cam with rounded ends determine the diametrical on the rotary output shaft of an electric micromotor is attached. The locking position is established when the cam is vertical stands (with its main pages standing vertically), and vice versa.

The operating time of the device is all the more for a given feed source greater, the lower the friction against the drive by the micromotor. To for this purpose there is an upper and a lower play in this type of device with respect to the ends of themselves in the vertical position or in the locking position located cam provided, this game is relatively large to ensure that there is no friction with the rotation of the cam by the Micromotor results.

As a result, the right-angled cam is cantilevered. On this cantilever act on the considerable forces that are created if rotation is attempted while the device is in the Locked position. These forces are entirely from the cantilever Part included and are on the shaft of the micromotor in the form of bending moments transmitted, which cause deformations and a permanent game, which further intensifies the process and the negative effects every time be enlarged.

Another disadvantage of this type of known device is that a great precision with regard to the arrangement of the cam in the vertical Locking position is required; in such micromotors there are no means which ensure this precision so that some other complementary agent is required which detects and ensures the vertical locking position, thereby reducing costs and a space requirement, the availability of which is critical.

If this vertical locking position of the right-angled cam is not exact the game is greater at the ends of this cam, which results in three negatives Effects result: first, the bending moment on the shaft of the micromotor an attempted rotation enlarged; secondly, a torque occurs on the shaft of the Micromotor on; third, the locking position loses strength and the Device is not very reliable.

The invention has for its object a locking cylinder of the beginning to create mentioned type, in which these disadvantages are eliminated and in low-friction operation has high reliability.

This object is achieved by the features specified in claims 1 and 22.

Advantageous refinements and developments result from the Dependent claims.

The electronic lock cylinder according to the invention comprises in a preferred one Design the following: a double-body stator housing with a European profile in Shape of a bulb for actuating the locking cylinder from the outside and the Inside of the lock; respective outer and inner rotatable cores or Rotors that rotate inside the body of the stator housing and each a channel for the insertion of the shaft of a corresponding electronic Have a key which is provided with an interactive electronic circuit, which is electronically encodable; an electrical contact that is in a radial seat is arranged in each of the outer and inner rotors, that with the key channel communicates at the point where any of two electrical Contacts that face each other on the shaft of the electronic key are provided, is arranged when this is operationally in the key channel is inserted; an annular electrical contact path connecting each of the outer and inner rotors and on the inside electrically with the respective electrical contact of these rotors is connected; an electric one Sliding contact that in each rotor with the outside of the annular contact track is in electrical connection and elastic against a second compression spring is biased; an electronic processor unit that is electrically connected to the electrical sliding contacts of the outer and inner rotor is connected; a vertically retractable latch that locks in against a compression coil spring Radial direction is attached to the outer rotor and part of one Electromechanical device for blocking the rotation of the outer rotor forms, which is electrically connected to the electronic processor unit; one first eccentric installed between the outer and inner rotors; a outer sleeve, which is in the axial direction between the first eccentric and the outer Rotor is inserted; an inner sleeve that extends axially between the first Eccentric and the inner rotor is inserted; an outer slider that with Axial play is arranged between the first eccentric and the outer rotor, the outer slider facing the inside of the outer sleeve and slidable relative to a first flat diametrical end of the outer rotor is arranged, which is arranged inside the outer slider; an inner Slider that has axial play between the first eccentric and the inner rotor is arranged, the inner slider opposite the inside of the inner Sleeve and slidable relative to a second flat diametrical end is arranged, which is arranged inside the inner slide, a first Module housing that is adjacent to the inside of a first recess outer rotor has adapted dimensions, the first recess in the double-body stator housing is arranged, the first module housing the electrical sliding contact of the outer rotor, the electronic processor unit and the electromechanical device for locking the rotation of the outer Contains rotors; a second module housing attached to the inside of a second Has recess adjacent to the inner rotor adapted dimensions, wherein the recess is arranged in the double-body stator housing and wherein the second module housing an autonomous electrical power source and the contains electrical sliding contact that corresponds to the inner rotor; and one electrical conductor that is switched between the first and second module housings is.

Regardless of the type of lock cylinder, the electromechanical includes Device for blocking the rotation of the outer rotor, preferably one Bracket, an autonomous electric micromotor that rotates horizontally Output shaft and is arranged in a seat of the bracket, a vertical disc cams, a vertically retractable latch that fits into the seat of the Bracket is arranged and projects over the upper level of the bracket, a Compression coil spring extending vertically between respective first and second horizontal walls of the holder or the retractable latch is arranged, a base that is under the bracket in vertical alignment with the retractable latch is attached, and a ball that is free in a changeable Space is arranged between the disc cam, the retractable Latch and the base part is bounded; the disc cam being vertical Has cam face, which is opposite the ball in the horizontal direction and protrudes continuously; the retractable latch is level Top in constant contact with the circumference of the outer sleeve with the Has flattening in the circumferential direction, the retractable latch opposite to the flat upper end face on its underside an inclined Plane with a concave cross profile that of an arc with a larger Radius as the sphere is circumscribed and opposite the sphere; being the Base part on its top a horizontal plane with a concave cross profile has, which is circumscribed by an arc with a larger radius than the ball and is in constant contact with the ball and in the vertical direction of the inclined Opposite level of the retractable latch; with the ball one Has a diameter sufficient to simultaneously with the cam face, the inclined concave plane of the retractable latch and the concave to be in horizontal plane of the base part in contact, being in the longitudinal direction with this horizontal concave plane between the sphere and its contact point the inclined concave plane has a maximum distance equal to Change the horizontal projection between the more or less protruding portions of the cam face.

In the device according to the invention occurs the vertically displaceable part that the Locking does not result in direct (in this case the retractable latch) Contact with the cam (in this case a disc cam), which was originally the Locking or release states of the device are determined. The relationship between the retractable latch and the disc cam is a ball, which is freely supported along the concave plane of the bracket fastened base part can move and by means of the inclined concave plane formed which forms part of the retractable latch itself.

The disc cam only requires play on its back because of the ball is free and their contact with the rotating disc cam is not essential Causes friction, so that the micromotor does not exert a greater force and not the Independence of the available electrical supply is impaired.

The locking position is formed when the disc cam with its on strongest projecting part of its cam end face is opposite the ball; here this ball stands with the inclined concave plane of the retractable Riegel in contact without the simultaneous contact with the horizontal concave level of the base part and with the cam end face is lifted.

If a rotation is forced in this locking position, the will on retractable latch force generated to a large extent on the bracket over the Transfer base part. Only the rest of the power is transferred to the cam, and this in a way that is hardly disadvantageous for the output shaft of the micromotor, because this force in a direction parallel to this shaft of the micromotor and in a small amount radial distance from this is transmitted; this force can only continue transmitted along the very greatly reduced game, which in this case is only present on the back of the cam. This solution gives one great robustness for the device and reliable operation.

Another feature of the invention is that on the back of the Disc cam a projection is provided which is arranged in the area in which the cam end surface protrudes furthest towards the ball, this protrusion spanning a distance less than the game, that is present on the remaining part of the rear of the disc cam, which is not of the lead is taken.

This projection enables a reduction in the back play of the disc cam, especially in the area of this disc cam in which the Locking state is caused; therefore this lead does not change the frictionless properties with the remaining part of the rotary movement of the Scheibennockens.

It should be emphasized the extensive possibility of adaptation that results from the modular construction between first and second housings, which over a electrical conductors are interconnected. You can on a particularly large Stator body (for doors with a special width that is larger than the normal) simple be applied in that the electrical connection conductor becomes longer. Furthermore, an application to stator bodies with other profiles is possible are always wider than European profiles. Furthermore, the application for a electrical remote supply possible, for this purpose an external electrical Conductor is provided with the first module housing and a power source is connected outside the lock cylinder.

Regarding the electrical connection between the electronic processor unit and the electronic key that this electrical connection is maintained throughout the rotation of the rotor due to the arrangement of the annular contact track compared to the electrical Contact and the electrical sliding contact. This enables an interaction regarding data and command transmission during the rotary movement starting from the special starting time at which the coding of the electronic key when it is simply inserted into the key channel has been validated.

The fact that the annular contact path, the electrical contact of the rotor and the electrical sliding contact inside the Lock cylinders are protected.

Explanation of a preferred embodiment

Figure 1 shows a preferred embodiment of the new electronic Lock cylinder, which has an electronic key (64) from both the Outside as well as the inside of the lock can be actuated. This electronic lock cylinder has a double body stator housing (1) with European Profile in the form of a pear for actuating the locking cylinder of the Outside and inside of the castle from. Respectively on the outside of the Locks or a door lying or outer and on the inside of the lock or a rotating or inner rotating cores or rotors (2 or 3) are in the Inside the body of the stator housing (1) rotatably arranged and each have a channel (2a, 3a) for the insertion of the shaft (65) of a corresponding one electronic key (64) with an interactive electronic circuit is provided, which is electronically encodable. An electrical contact (5) is in one radial seat of each of the outer and inner rotors (2 and 3), and this seat is connected to the key channel (2a, 3a) and is in place is arranged to lie on one or the other of the electrical contacts come opposite on the shaft (65) of the electronic key (64) are arranged when this is operationally in the key channel (2a, 3a) is used. An electrically conductive annular contact track surrounds each of the outer (2) and inner (3) rotors and is electrically on the inside with the respective electrical contact (5) of the rotors (2, 3) in connection. An electric conductive sliding contact (7) is on each of the rotors (2, 3) electrically with the Outside of the annular electrical contact track (6) in connection and is biased elastically by a second compression spring (7a). An electronic one Processor unit (31) is electrical with the electrical sliding contacts (7) of the outer (2) and inner (3) rotor connected.

A vertically retractable bolt (16) is pretensioned by a compression coil spring (17) attached in the radial direction to the outer rotor (2) and forms part of an electromechanical device for blocking the rotation thereof outer rotor (2) electrically with the electronic processor unit (31) connected is.

A first eccentric (4) is between the outer rotor (2) and the inner rotor (3) installed. An outer sleeve (32) is in the axial direction between the first Eccentric (4) and the outer rotor (2) inserted while an inner sleeve (35) in the axial direction between the first eccentric (4) and the inner rotor (3) is inserted. An outer slide (41) is with axial play between the first Eccentric (4) and the outer rotor (2) installed, the outer slide (41) towards the inside of the outer sleeve (32) and towards a first plane diametrically flattened end (47) of the outer rotor (2) is arranged displaceably, this diametrically flattened end (47) inside this outer Slider (41) is arranged. An inner slide (44) is with axial play between the first eccentric (4) and the inner rotor (3) installed, the inner Slider (44) against the inside of the inner sleeve (35) and against one second flat diametrically flattened end (48) of the inner rotor (3) is arranged, which is arranged inside this inner slide (44).

A first module housing (8) in the locking cylinder has dimensions that the inside of a first recess (1a) are adapted to the outer rotor (2), which is formed in the double-body stator housing (1), the first module housing the electrical sliding contact (7) of the outer rotor (2) electronic processor unit (31) and the electromechanical device for Locking the rotation of the outer rotor (2) contains.

A second module housing (9) points to the inside of a second recess (1b) adapted dimensions, which is adjacent to the inner rotor (3) and in which Double-body stator housing (1) is formed, the second module housing (9) an independent electrical supply source and the electrical sliding contact (7) contains, which corresponds to the inner rotor (3).

An electrical conductor (10) is between the first (8) and second (9) module housings turned on.

The unit of the electrical contact (5), the annular contact track (6) and the electrical sliding contact (7) causes the the electronic key (64) performs a permanent connection between the electronic key (64) and the processor unit (31) is what a interactive reading, transmission and modification of data enables which results in a wide range of applications. This unit repeats with respect to the inner or inner rotor (3).

If it is necessary that the first module housing (8) with an external power source is connected, an external electrical conductor (10a) is provided, which with the first module housing (8) and a supply source outside the locking cylinder connected is.

The modularity that results from the first (8) and second (9) module housing can can also be used when the locking cylinder is a single body with a European Profile is. In this case it is necessary to have an auxiliary recess in the door to produce for the second module housing (9), which is very simple.

The aforementioned electromechanical device for locking the rotary movement of the outer rotor (2) comprises a holder (11), an electric micromotor (12), which has a rotatable horizontal output shaft (13) and in a seat (14) the bracket (11) is arranged, a vertical disc cam (15), a vertical retractable latch (16) which is arranged in the seat (14) of the holder (11) and protrudes from the upper level of the bracket (11), a compression coil spring (17), which in the vertical direction between the respective first (27) and second (28) horizontal walls of the holder (11) or of the retractable latch (16) is arranged, a base part (18) below the holder (11) in vertical Alignment is secured with the retractable latch (16) and a ball (19), which is freely arranged in a changeable space between the Disc cam (15), the retractable latch (16) and the base part (18) is delimited; the disc cam (15) having a vertically oriented cam face (20) which is opposite the ball (19) in the horizontal direction and with a continuously changing distance from the back (24) of the Disc cam protrudes. The retractable latch (16) has a flat top End face (21) in constant contact with the circumference of the outer sleeve (32), which has a flattened portion (33). The bolt (16) still points to it the flat upper end face (21) opposite side obliquely on the Cam end face facing plane or end face (22) with a concave Cross profile, which has an arc with a larger radius than the ball (19) and opposite the ball (19). The base part (18) has one on its top horizontal plane or surface (23) with a concave cross profile on one Arc with a larger radius than the ball (19) in constant contact with the Ball (19) stands and in the vertical direction of the inclined lower end face (22) of the retractable bolt (16) is opposite.
