Detailed description of the invention

1 A, 1 B, 1 C and 1 D show a side view, top view, axial section and sectional plan view of an electronic locking system 10 consisting of a standardized, on a door leaf 12 or the like. Mountable recessed handle 14, in the lockable handle lever 16 with its one end 18 around the door leaf 12 parallel axis 20 of the recessed grip 14 or of one held therein Drive shaft 22 for a rod lock 24, sash or the like. Swiveling is, and from a locking device 26 with which the handle lever 16 in its in Trough 14 pivoted position can be locked (by means of bolt 28).

This locking device 126 can according to FIGS. 9 and 10 outside the Area of the lever 116 may be arranged. This requires a change in the Trough to accommodate the locking device 126 and leads also to an increased overall length. It is cheaper, according to FIGS. 1A, 1B, 1C and 1 D the locking device 126 in an already existing breakthrough to provide, which is usually provided for a cylinder lock, but here in of appropriate shape, see FIG. 3, locking devices for Is made available. In this case, the operating lever 16 is modified required, while the trough can remain unchanged. The result is a shorter one Overall length.

a) ein Grundmodul 32 mit einem beweglichen Riegel 28, der eine Schwenkbewegung oder, wie hier, über eine Translationsbewegung in Richtung der Pfeile 30 ausführt, siehe die Fig. 3 und 4. Beim Ausfahren legt sich die Riegelzunge 28 in eine schlitzförmige Öffnung 34, die in der Stirnwand 36 des Handhebels 16 gebildet ist, siehe Fig. 1 A, 1 C und 4.

Basically, the locking unit is also modular and includes in particular the following interchangeable components:

a) a basic module 32 with a movable latch 28, which carries out a pivoting movement or, as here, via a translational movement in the direction of the arrows 30, see FIGS. 3 and 4. When extended, the latch tongue 28 lies in a slot-shaped opening 34, which is formed in the end wall 36 of the hand lever 16, see Fig. 1 A, 1 C and 4th

The latch forms an inclined surface 38 and also allows movement along the left arrowhead 30 against the force of the spring 40 similar to a door latch and thus allows the hand lever 16 to be pressed into the recess 14, without having to operate the lock itself: when the lever is swung in 16, the inclined surface 38 of the bolt 28 reaches the edge of the end wall 36 and is pushed back by this against the force of the spring 40 and slides along the End wall until it reaches the area of the opening 34, whereupon due to the spring force of the spring 40 the latch back out into the Locked position is pushed.

In the locked locking position, the latch 28 holds the handle lever 16 in its pivoted or folded position firmly. Unlocking this spring-loaded case 38 is carried out by means of a cam track 42 into which the eccentric 44th of a geared motor 48 engages when the eccentric 44 in Direction of arrow 46 rotates. The eccentric pushes the rotary motion Latch 30 against the force of the spring 40 along a guide 50 (FIG. 4) or 51 (FIG. 1D) so far that the bolt 28 comes out of the opening 34 and the Hand lever, which has been pressed in, for example, against spring force, releases and can swing out.

As soon as the eccentric 44 leaves the cam track at the edge 52 again, the Latch 28 is released and is returned to the outside by the force of the spring pushed position.

A device for supplying an electrical device is used to drive the motor 48 Voltage that can also be contained in the basic module, for example in Form of an (optionally rechargeable) battery that can be stored in a space this battery is housed, see reference number 54. On the basic module 32 is a Application module 56 attachable or attachable, which has the shape of an aperture and thus closes the space of the basic module in which the motor is contained, see Fig. 1 C and 2. The outer surface of the aperture extends through an opening or Incision 58 in the free end of the hand lever 16, and carries controls for the locking movement of the locking device 26 of the basic module 32. In Fig. 1 B carries the cover of the application module 56 one of several, here 12 keys existing keyboard 60 and a multi-digit, such as 5-digit character display 62 and one or more light-emitting diodes 64. basic module 32 and application module 56 together form an "opener module" 57 according to the module concept in FIG. 13.

The application module 56 can be replaced and, for example, by a 6, replace the one instead of the keyboard 60 Reading device for a magnetic stripe of a magnetic stripe card, which by slot 66 must be pulled to read data from the magnetic stripe.

Light-emitting diodes 64 or other display devices can also be used be provided, see FIG. 6.

7 shows an application module 356, which in connection with the same basic module 32, according to FIGS. 5 and 6, makes it possible to read a chip card, which is inserted into a slot 68.

8 finally shows an application module 456 with a biometric Fingerprint reader 70 with the thumb or finger through side walls 72 is performed.

The basic module can also be connected to a network via cable connections 74 in FIG. not shown here, are connected.

An application module in which a transmitting / receiving device is not shown is intended for radio waves. The same applies to an application module, the one Infrared interface forms. An application module is also not shown a transponder.

The basic module, and possibly also the application modules, are usually one Data storage include, the read data a microprocessor, which in the Basic module can be made available.

As can be seen from the above, this enables the invention Locking system to create a range of electronic locks which can be used in standard recessed grips. There is only one Replacement of the handle and lock shoulder required while the complete Disassembly of the handle mechanism is unnecessary. Furthermore, the castle engages directly the handle and thus provides a particularly stable protection against unauthorized opening. The system according to the invention enables variants for operation without power supply (battery-powered) and for continuous operation with power supply. This can also be combined by continuous operation with mains and emergency operation without Network with battery is made possible.

As already mentioned, the construction is very simple and consists of FIG. 11 a basic module (including battery module, control module and drive module) and an application module. The basic module contains a voltage generation, whereby for example from a battery voltage of 1.2 V for the operation of the Microprocessor necessary voltage of 5 V can be generated. The voltage the battery or accumulator are monitored during operation and State of charge weaknesses optically with, for example, the light emitting diodes (LED) displayed. When connected to the network, this message can also be evaluated centrally be, e.g. B. in the control module of a center 78, which is also a software package (Software module 80) (FIG. 13). A is connected to the basic module Battery module with two 1.5 V rechargeable batteries or a battery, for example Voltage terminal adapter.

The interchangeability of the application module enables a code lock (Code is entered by keyboard), a transponder lock, one Fingerprint identification (using biometrics), as well as a network version, which is also available in Combination with the above applications is possible. Furthermore is a Application module with magnetic stripe, chip card and transponder possible.

Code keyboard :

The application module is placed on the basic module and receives z. B. at Code lock a 12-way keyboard and a digit display with 4 digits. More jobs are possible, but mostly not necessary.

An LED shows the input status and optionally the battery status.

In the operating state with external power supply z. B. in the display z. B. 4 dashes are displayed, in operation without this the display is shown after actuation a button to save electricity. It will only be a 4-digit number (on request multi-digit code entered. The lock is then entered correctly 4th position open. When entering a programming code (e.g. 4 digits plus 4 digits program or more) a code can be added or deleted.

Transponder :

When using a transponder, the application module is in turn on the Basic module attached, but contains a closed panel and a light emitting diode. Also a hidden read contact. Then transponders are used, which are wound on a permanent magnet. An LED shows that Input status or optionally the battery status. The module can also be self-sufficient function.

The operational function would be e.g. B. such that in the operating state with external Power supply the LED lights up red. When operating without external Power supply is displayed in green after the correct one is available Magnetic transponders. The code is now read from the transponder, the lock opens when the transponder is correct. Permissions are over assign a master transponder or via a connected PC / network.

Network :

When using a network (Fig. 12), an application module on the Basic module put on and receives a closed panel and z. Legs Led. An LED shows the input status and optionally the Mains connection.

In the operating state (only with external power supply, e.g. using power supply 84 The LED is red via line 82, 182, 282 (FIG. 12)). After the opening command via network 86 and line 186, 286, 384 this is red. For many network-compatible devices, there is a control module 76 (FIG. 13), which the can operate individual devices 57.

Fingerprint :

If the fingerprint recognition method or biometrics is used, this will be Application module placed on the basic module and receives an aperture integrated fingerprint sensor and a light emitting diode. An LED shows that Input status and optionally the network connection.

In the operating state (only with an external power supply, e.g. according to Fig. 12) the LED is red. After the opening command via the control module 76, this is green. For several fingerprint devices z. B. each have a control module, which can operate the individual devices and the data from the sensors on the doors can evaluate.

The data for the finger are contained in the control module.

The basic module designated 32 in FIG. 3 is made with its upper, possibly narrower Part inserted into the recessed grip from below and screwed to it, e.g. B. By means Screws 33. Then the selected application module 56 is inserted from above the recessed grip and placed on the upper end of the basic module 32 and z. B. also screwed and electrically connected (e.g. via cable or Connector).

11, the concept of the modular construction is again clear excelled. Thus, a system equipped according to the invention consists of one Sensor unit that is connected to the control electronics, also a module. With the Control electronics is also connected to the drive unit, which is the bolt movement allows.

The control electronics can optionally either with an external solar cell, with a optional external battery or accumulator or with an internal battery or Battery device must be connected.

Internal is the sensor with sensor unit, the drive unit, the control electronics and an internal battery.

The solar cell or the external battery is external. To externally optional The sensor unit as well as the Control electronics can be equipped with appropriate voltage contacts.

A voltage and charging feed can also be fed to the control electronics (to charge a battery), a digital opening input (to an external a digital closing output (order trigger an external closing process) and a serial interface 88 (to a network 86), see FIG. 12.

Fig. 12 shows how several modules can be networked together. So are 12 modules 1 and 2 via line 82 with a Power supply 84 connected while modules 3 and 4 of module 2 are supplied via lines 386, 286. Module 1 supplies a first interface Data. Module 2, 3 and 4 are supplied with data by the interface 88. This again stands over block TCP / IP with the Internet or another network or with further modules according to the invention or electronic Locking control centers 78 ("EL-KEY MASTER") in connection.
