Description

Background of the Invention

The invention relates to an electrically lockable pivot lever actuation, consisting of a trough which can be placed on a door leaf or the like, in which a Actuating lever for a lock, such as a cam lock or rod lock in such a way is mounted that he from a position swung out of the trough, in which he a Lock actuation enables a position pivoted into the trough can be brought in which it does not allow a shutter actuation and in which it can be locked by an electromechanical locking device, the electromechanical Locking device insertable into the trough Representing assembly, of which a pin or projection for locking the Actuating lever extend or by means of an electrical control signal can be swung out.

Brief description of the state of the art

Such a pivot lever operation is already known, see for. B. DE 298 06 974 U or EP 0 824 624 B1. The known pivot lever actuation from EP 0 824 624 B1 requires a special one Arranged on the door frame so that it works correctly. It is for many Use cases too expensive.

Object of the invention

The object of the invention is the electrically lockable pivot lever actuation to change the type mentioned in that it is simple and in particular does not require any special facilities that take place on the door leaf or the like. are built on the door frame or the like.

In particular, the arrangement should be able to be designed so that in the essential conventional swivel lever locks can be used.

Another task is the one used up to now, also with the status of Technology available keys for a cylinder lock or the like do.

solutions

The task is solved in that the operating lever on his Top side in the area of the assembly has an opening through which pivoted-in operating lever, the structural unit used in the trough is accessible.

This has the advantage that no electrical connection to the Operating lever must be created so that the construction is simplified and can be made reliable.

In particular, there is no need for flexibly laid cables and plug contact constructions, that are very prone to failure.

The features of claim 1 ensure that, on the one hand, the invention Swing lever operation with previously used swivel lever operations without electrical locking can be equipped, for example, in that this unit in conventional actuation lever - possibly with a slight Processing - can be used, on the other hand there is the possibility of previous ones Swivel lever operations simply by exchanging for the invention Switch version.

The electrical interlock provided in EP 0 824 624 B1 used cylinder with associated cylinder key unnecessary, which the The advantage is that a key that was previously necessary is no longer required, ie cannot get lost or fall into the wrong hands.

There are several ways to access the assembly. A special one favorable embodiment arises when the opening has the size and shape of a fingerprint, and if the accessible area of the assembly is one Fingerprint sensor surface (also known as a biometric sensor device) having. This configuration gives the possibility of using the Thumb of an operator placed on the opening of the operating lever is touching the fingerprint sensor surface of the assembly corresponding electronic devices within the structural unit thereof Analyze fingerprint lines to determine if that matches the fingerprint belonging person enjoys access to the control cabinet. Is this the Case, the assembly can respond so that it provides a drive signal for the drive of their projection or pin and swings it in or retracts and thereby the lock opens, whereupon the operator releases the operating lever can swing out and open the shutter.

Another possibility is that of opening in the operating lever to design that light (be it visible or invisible) can pass through, and if there is an optical sensor surface on the surface of the unit accessible to light is applied, which responds to the light signal in a certain way, provided that the light has a temporal or local modulation (pattern) that represents an identifier likes that of the electromechanical downstream of the sensor surface Locking device signals that the signal pattern generated by the light comes from an operator who is authorized to operate the control cabinet or the like. to open.

Another alternative is to place a keyboard on top of the assembly is accessible through the opening. Then, for example, a simple one Pen or with a pointed finger pressed the keyboard and a z. B. encoded Message can be entered, which in turn can serve the Unlock locking device.

Another alternative is through this opening to one in the Access to the unit arranged key actuation, which is quite in the form the previous cylinder key arrangement can be, but not in the handle here is stored, as in the prior art, but instead in that of the trough worn unit. The operating lever is therefore slimmer and lighter manageable.

The key in turn is a pulse trigger or other generation a signal possible, which in turn leads to the fact that the locking device is unlocked electrically.

You can install a transponder device in the unit.

The transponder device has the further advantage that it Outdoor equipment can absorb energy, for example, with this energy Trigger opening process without z. B. battery devices may be present would.

Another way to dispense with a battery or to charge it To simplify, can be achieved in that in the area of the opening on the Unit is provided a photovoltaic arrangement, the opening of this Makes equipment accessible to the outside light.

To facilitate the detection processes, especially at higher ones Security levels, it is beneficial if the assembly uses a microprocessor chip which can perform sufficiently complex calculations to high levels of security, for example when entering codes or when entering To allow fingerprint scanning.

The chip has the further advantage that an embodiment is possible in which the Overall arrangement is connected to a network, for example with a internal network that reports the status of the lock to a remote control center. Conversely, the remote control center can also unlock the Closure can be made possible, for example in the event of an emergency or the like.

Such an interface for connection to a data network or the like Wiring done or advantageously by a wireless connection, such as for example, through an infrared interface to which, for example, one with a mobile phone provided with the appropriate counter interface can.

According to yet another development of the invention, the operating lever on its top a sliding or swiveling cover for the Wearing breakthrough. This makes it possible to arrange the one located under this breakthrough Device, such as sensor device, from damage and To protect pollution.

It has been found to be particularly favorable mechanically if the structural unit is a includes cup-shaped housing, the bottom of which is accessible from the outside Storage space for accessible through the opening in the hand lever Has sensor devices or the like. If the assembly is a cup-shaped Enclosed housing, it is advantageous if its side wall has an opening to Passage of the locking pin or projection. Preferably one such a unit with a cup-shaped housing has a flange-like edge, which edge has holes for the passage of clamping screws with which the Cup (together with a lid, for example) in a corresponding one The recess area of the trough can be accommodated and fixed. The Fastening screws could also serve to secure the trough within one To jam door leaf or the like.

It has proven to be useful if the unit is an electromotive Drive includes the locking pin or the control Locking projection alternately extends or retracts. An actuation pulse can for example, cause the locking pin or locking projection extends and locks the pivoted lever in the recess while a repeated impulse then leads to a retraction of the pin or the projection, and thus releases the operating lever.

This type of actuation of the locking pin or locking projection is particularly reliable and energy-saving.

The microprocessor can also be used to save power Switch off circuit areas after a certain rest period. As soon as then if any trigger signal arrives from the sensor surface, the Microprocessor then immediately turns the power on again. In this way a (rechargeable Power storage) Battery protected.

The activation can take place, for example, in that an existing Cover slide or the like. Is pushed away, so that the sensor surface for example hit by light. Alternatively, the slider itself can also be used have a contact which, when actuated, sends a pulse to the Microelectronic device supplies to put them into operation.

In this way it is possible to operate the arrangement unexpectedly for months, d. that is, bridges long operating times with a battery or a battery charge can be.

The pivot lever actuation according to the invention can be done with very different Use closures, for example for cam locks, at Rod closures, etc.

Best ways to carry out the invention

1A, an electrically lockable pivot lever actuation 10 is shown, consisting of a trough 14 which can be placed on a door leaf 12 or the like, in which a Actuating lever 16 is mounted such that it comes from one of the trough pivoted position, see the pivot axis 18, in one Lock actuation is made possible, for. B. by rotating the pivoted Hand lever 16 about the axis 20 z. B. a flat bar lock box 22, at which rotation, for example, in the lock case 22 stored flat ribbon rods 24 are pushed outwards, with which pushing out in itself known way, see the prior art, a door leaf, for example, in one Frame is unlocked. Conversely, when the operating lever 16 in FIG. 1A shown pivoted position, a shutter operation is not allows. To in this position the hand lever and thus the lock To secure, is an electromechanical locking device that the Holds pivot lever 16 in its pivoted position.

According to the electromechanical locking device comprises an in the trough 14 insertable assembly 26, from which a pin or projection 28 to Locking the operating lever 16 by means of an electrical setting signal can be extended or swung out. When extending the pin 28 in the direction of Arrow 30 pushes the pin 28 into a bore 32, the one approach or one Partition wall 34 is formed by the bottom and a trough forming Side walls 36 of the actuating lever 16, see Fig. 3, are formed. The pencil thus holds the operating lever 16 in its pivoted position when he is extended. 3 and 4, see also the Fig. 1A, the operating lever 16 has on its top, that of the bottom wall of the trough-shaped profile 38 is formed, an opening in the area of the unit 26 40, through which the operating lever is pivoted in, as in FIG. 1A recognize that the unit 26 used in the trough 14 is accessible. The in the The embodiment shown in the figures shows an opening 40 which is of size and shape is designed so that a thumb or finger can be comfortably picked up, such that a larger part of the fingertip or the thumb on the under the Opening 40 accessible surface 42 of the assembly 26 comes to rest. This area 42 is in this case a so-called biometric sensor surface, which the individual can capture different fingerprint lines from person to person and a corresponding image signal to a processing device, such as a microprocessor chip 44 processed and compared with in the case of an entered comparison pattern in order generate a control pulse or a control signal if this matches controls an electric linear drive 46, which then, for example, turns off the pin 28 withdraws the locked position in the direction of arrow 48 and thereby Actuating lever 16 for unhooking around the shaft 18 releases. The opening 40 in the Actuation lever 16 has the shape of the fingertip of a thumb or index finger with matching bevels 50, 52 so that the surface of the fingertip is not unnecessarily distorted when the thumb is pressed into the opening 40, which increases the accuracy of fingerprint line detection.

It is advantageous that the locking opening 32 is enclosed on all sides, so that Manipulations of unauthorized persons on the locking device are difficult.

Instead of a biometric sensor device as described above an alternative embodiment is also conceivable, for example in the Form that the surface 42 below the opening 40 is an optical Represents sensor surface. By irradiating this area with a certain light local fluctuation or patterning (locally modulated light) or pulsed light certain coding (time-modulated light) can also be a Sensor output signal are generated, which is processed accordingly to a Opening of the locking device leads. In pulsed light, scatter influences play no role, so that the opening 40 is then also through a not clearly translucent, but opalized glass or plexiglass could be closed while at a surface modulated light radiation it would be important that such protective wall is translucent to this spatial distribution of the Imaging light unaffected by stray influences on the sensor surface.

The surface 42 could also carry a keyboard, for example a keyboard of four Keys that would allow the entry of encoded data by clicking on this Keys are pressed, for example with a pen, or if the size is sufficient the individual buttons with a fingertip.

A normal key operation is also conceivable, although this has the disadvantage that that a key must be kept that can be lost is also a normal key operation z. B. connected to a cylinder, the relatively much Takes up space.

The surface 42 can also be a so-called transponder, I got a coil from a second one near the operating lever 16 passed coil absorbs energy, for example, to the linear motor 28 Moving the pen 30 to provide energy, and at the same time To transmit digital information that indicates, for example, whether the Transponder device outside of the operating lever 16 by one approved operator is worn. A transponder device has the advantage that it also stores information in the memory chip of the microprocessor device Swing lever operation can enroll, for example, the Admission code change and actuation times and actuation frequencies read and later read out again and in a data processing device to process.

For example, the time and day the cabinet was opened be logged.

Such a transponder 111 can also be installed on a key 110, as in Fig. 6 with one of e.g. Plastic molded key 110 is shown.

It is particularly favorable if the key is also next to the Transponder 111 has a magnet 112.

The key 110 could then be locked electrically Cooperate lever actuation in such a way that the key 110 arranged magnet 112 when the key 110 approaches the The power supply for this Swing lever operation (e.g. via one in the swivel lever operation housed reed contact) switches on.

In particular, the key could have a contact that can be triggered by a magnetic field, such as Riedkontakt, which is in one in the electrically lockable Swivel lever actuation arranged transponder reader is such cooperate that when the magnet approaches the contact Turns on the power supply of at least the reader.

Instead of the circuit and the motor drive or battery via a transponder To supply energy, this can also be supplied by a photovoltaic device if the opening 40 is a photovoltaic arranged on the assembly Make the device accessible to outside light so that it e.g. photodiodes comprehensive facility can generate energy due to the striking light.

Another alternative to the power supply is the arrangement of an accumulator 54 or a replaceable battery.

In order to protect the sensor surface 42 against contamination and damage Depending on the application, it may be convenient to have the actuating lever on its top with a slidable or pivotable cover for the opening 40 to provided which cover 56 can be pivoted away, for example, about an axis 58 or is displaceable along the lever axis.

As can be seen in FIG. 1B, the structural unit comprises a cup-shaped housing 60, the bottom 62 of an externally accessible receiving space 64 for through the Opening 40 in the hand lever 16 accessible sensor devices 42 or the like. having. Furthermore, the housing 60 has a flange-like edge 66, which edge has bores 68 by the fastening or clamping screws 70 can be passed, with which the housing 60 after insertion into a corresponding receiving space 62 of the trough 14, see FIG. 2, thereby can be determined that, after placing a lid 72 with corresponding bores 74 cap screws through these bores 74, 68, and the holes 78, 76 can be inserted, which the one hand with the cup press its ring shoulder 77 onto the flange 66 of the cup 60, on the other hand with an edge 79 clamps the door leaf between itself and the trough 14, so that the entire arrangement is clamped at this point. Is dashed 1A, see also the other end of the trough 14 in a similar manner can be clamped by a lock case or gearbox 80 is provided in such a way that the 170 there with the help of screws thin wall 12 between the trough 14 on the one hand and the box 80 on the other is pinched. Box 80 also shows dashed lines outstanding locking rods 24 and a lock drive shaft 82, the on the one hand with a pinion arranged inside the housing 80, not shown, is connected, on the other hand, the pivot lever 16 at its free end by means of the pin axis 18.

Fig. 5 shows a schematic representation of the operation of the swivel lever actuation according to the invention. The block is shown Operating lever 16, which is held within the trough 14 by a pin 28 when the linear drive 46 has pushed it into the locking position. The Position of the motor or drive can be checked by a microprocessor MY be, which in turn connects the drive 46 to a battery 54 to him to deliver a current pulse. To charge the battery 54, if it is one Actuates accumulator, a generator G could serve, alternatively a photovoltaic Device S, or alternatively a transponder device T. The microprocessor MY in turn, it is controlled, for example, by the biometric sensor device 42, which delivers signals triggered by thumb through opening 40, and which through a protective cover device 56 can be covered, by sliding or opening the opening 40 by means of the protective cover 56 a switch may be operated, which may trigger the start of operation of the overall arrangement.
