Abstract

Device has a cradle (14) fitted to a door panel (12) or similar with a lock actuating lever (16) that can be pivoted out of the cradle to enable a lock to be actuated and into the cradle, where it is retained by an electromechanical locking device, to prevent actuation. Electromechanical locking device is a unit set into the cradle from which a pin (28) or protrusion can be deployed by an electric drive signal to lock the actuating lever. Independent claims are also included for the following: the use of an electrically locking pivoting lever actuator for a rod lock, casement lock and bar lock and a key for an electrically locking pivoting lever actuator.

Description

The invention relates to an electrically lockable pivot lever actuation, consisting of a trough that 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 operation and in which it can be locked by an electromechanical locking device.

Such a pivot lever operation is already known, see for. B. EP 0 824 624 B1. The known swivel lever actuation requires a special one Arranged on the door frame so that it works correctly. It is for many Use cases too expensive, so that it is the object of the invention, the electrical lockable pivot lever actuation of the type mentioned to modify that it is simple and in particular not a special one Requires facilities that are on the door frame or on the door panel or the like Like. are built.

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.

The problem is solved in that the electromechanical Locking device can be inserted or integrated 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.

These features 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 operating 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 so far is at the state of the Technology used cylinders with the corresponding cylinder key dispensable, 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. Especially It is advantageous if, according to a further development, the handle on its top in Area of the assembly has an opening through which at 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, flexible cables and plug-in contact constructions are no longer required are very prone to failure.  

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 an operator who is placed on the opening of the operating lever and touches the fingerprint sensor surface of the assembly by appropriate electronic devices within the unit whose fingerprint lines analyze to determine whether the person associated with the fingerprint Enjoys access authorization to the control cabinet. If this is the case, the Unit respond so that they have a drive signal for driving their projection outputs or pin and swings it in or retracted and thereby the lock opens, whereupon the operator swings out the operating lever and can open the shutter.

Another possibility is to open the 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 signal patterns generated by the light comes from an operator who is authorized to the control cabinet or the like to open. Another alternative is to use a keyboard on the assembly to be arranged, which is accessible through the opening. Then with help, for example a simple pen or with a pointed finger, the keyboard and one e.g. B. coded 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 of a signal possible, which in turn leads to the fact that the locking device is unlocked electrically.

If you install a transponder device in the unit, you may be able to even the opening in the hand lever can be dispensed with, since the electromagnetic Wave by means of which the transponder device can be actuated by the Material of a hand lever when it is e.g. B. is made of plastic, without large Problems can get through.

The transponder device has the further advantage that it is different from the Outdoor facility can absorb energy, for example, with this energy Trigger opening process without z. B. battery devices may be present ought to.

Another way to make a battery unnecessary 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 convenient 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, an unlocking of the lock can also be carried out from the one control center  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 Pollution is protected.

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 the side wall of an opening to Has 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 tab 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.

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 Pollution is protected.

The microprocessor can also be used to save power Switch off circuit areas after a certain rest period. As soon as then any trigger signal arrives from the sensor surface, the microprocessor switches the power supply then immediately on again. This way, a Possibly provided in the facility (rechargeable electricity energy storage) Battery protected.

The activation can take place, for example, in that an existing one Cover slide or the like. Is pushed away, so that the sensor surface, for example is struck by light. Alternatively, the slide itself can have a contact have a pulse that delivers a pulse to the microelectronic device when actuated, to put it 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.

The invention is explained in more detail below with the aid of exemplary embodiments which  are shown in the drawings.

Fig. 6 shows a key for transponder operation.

In Fig. 1A, an electrically blockable swiveling lever control 10 is shown consisting of a on a door leaf 12 or the like. Attachable trough 14, in which an actuating lever 16 is mounted such that it, from a swung out of the trough position, see the Ausschwenkachse 18 in which a closure operation is made possible, e.g. 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 box 22 stored flat bars 24 are pushed outwards, when sliding out in a known manner, see the prior art, a door leaf is unlocked, for example, in a frame. Conversely, if the actuating lever 16 is in the pivoted -in position shown in FIG. 1A, actuation of the lock is not possible. In order to secure the hand lever and thus the closure in this position, an electromechanical locking device is used which holds the pivot lever 16 in its pivoted-in position.

According to the invention, the electromechanical locking device 10 comprises an assembly 26 which can be inserted into the trough 14 and from which a pin or projection 28 for locking the actuating lever 16 can be extended or swung out by means of an electrical setting signal. When the pin 28 is extended in the direction of the arrow 30 , the pin 28 penetrates into a bore 32 which is formed by an extension or an intermediate wall 34 which is formed by the bottom and side walls 36 , 38 of the actuating lever 16 which form a trough, see FIG are formed. 3,. The pin thus holds the operating lever 16 in its pivoted position when it is extended. As can further be seen from FIGS. 3 and 4, but also see FIG. 1A, the actuating lever 16 on its upper side, which is formed by the bottom wall of the trough-shaped profile 38 , has an opening 40 in the region of the structural unit 26 through which through when the actuating lever is pivoted in, as can be seen in FIG. 1A, the structural unit 26 inserted in the trough 14 is accessible. The embodiment shown in the figures shows an opening 40 which is designed in size and shape in such a way that a thumb or finger can be comfortably accommodated, such that a larger part of the fingertip or thumb on the surface 42 accessible under the opening 40 the assembly 26 comes to rest. In this case, this area 42 is a so-called biometric sensor area, which can detect the fingerprint lines that differ individually from person to person and processes a corresponding image signal to a processing device, such as a microprocessor chip 44 , and is compared with an input comparison pattern in order to find a match To generate a control pulse or a control signal that controls an electric linear drive 46 , which then, for example, then retracts the pin 28 from the locked position in the direction of the arrow 48 and thereby releases the actuating lever 16 for folding out about the shaft 18 . The opening 40 in the actuating lever 16 is in the form of the fingertip of a thumb or index finger with bevels 50 , 52 fitted thereon 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 the detection of the fingerprint lines enlarged.

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 lying below the opening 40 represents an optical sensor surface. By irradiating this area with a light of a certain local fluctuation or pattern (locally modulated light) or pulsed light of a certain coding (time-modulated light), a sensor output signal can also be produced, which leads to an opening of the locking device when processed accordingly. In the case of pulsed light, scattering influences play no role, so that the opening 40 could then also be closed by opalized glass or plexiglass, which is not clearly translucent, whereas in the case of flatly modulated light radiation it would be important for such a protective wall to be translucent to clear map this spatial distribution of light unaffected by scattering influences on the sensor surface.

The surface 42 could also carry a keyboard, for example a four-key keyboard, which would enable the entry of coded data by pressing on these keys, for example with a pen, or with a fingertip if the individual keys are sufficiently large.

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, which is a coil that takes up energy from a second coil passed near the actuating lever 16 , for example to supply the linear motor 28 with energy for displacing the pin 30 , and at the same time also to transmit digital information which, for example, indicates whether the transponder device is carried outside the actuating lever 16 by an authorized operator. A transponder device has the advantage that it can also write information into the memory chip of the microprocessor device of the rocker arm actuation, for example to change the approval coding and read actuation times and actuation frequencies and read them out later and process them in a data processing device.

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 shown in FIG . B. Plastic injection molded key 110 is shown.

It is particularly favorable if the key also has a magnet 112 in addition to the transponder 111 .

The key 110 could then interact with the electrically lockable pivot lever actuation in such a way that the magnet 112 arranged on the key 110 switches on the voltage supply for this pivot lever actuation when the key 110 approaches the pivot lever actuation (e.g. via a reed contact accommodated in the pivot lever actuation).

In particular, the key could have a contact that can be triggered by a magnetic field, such as Riedkontakt, which is in an 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 supplying energy to the circuit and the motor drive or battery via a transponder, this can also be supplied by a photovoltaic device, provided that the opening 40 makes a photovoltaic device arranged on the structural unit accessible to outside light. B. device comprising photodiodes can generate energy due to the incident 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 soiling and damage, it can be advantageous, depending on the application, to provide the actuating lever on its upper side with a displaceable or pivotable cover for the opening 40 , which cover 56 can be pivoted away, for example, about an axis 58 or along the lever axis is movable.

As can be seen in FIG. 1B, the structural unit comprises a cup-shaped housing 60 , the bottom 62 of which has a receiving space 64 which is accessible from the outside and for sensor devices 42 or the like which can be accessed through the opening 40 in the hand lever 16 . Furthermore, the housing 60 has a flange-like edge 66 , which edge has bores 68 through which fastening or clamping screws 70 can be passed, with which the housing 60, after being pushed into a corresponding receiving space 72 of the trough 14 , see FIG. 2, can be determined that, after placing a cover 72 with corresponding holes 74 cap screws through these holes 74 , 68 , and the holes 78 , 76 can be inserted, which press the cup with its annular shoulder 78 on the flange 66 of the cup 60 on the one hand , on the other hand with an edge 80 clamps the door leaf between itself and the trough 14 , so that the entire arrangement is held clamped at this point. Dashed lines, see Fig. 1A, that the other end of the trough 14 can also be clamped in a similar manner by providing a lock case or gear housing 80 in such a way that the thin wall 12 between there with the help of screws 170 the trough 14 on the one hand and the box 80 on the other hand is clamped. Also shown in dashed lines are locking rods 24 protruding from the box 80 and a lock drive shaft 82 which, on the one hand, is connected to a pinion (not shown) arranged inside the housing 80 , and on the other hand supports the pivot lever 16 at its free end by means of the pin axis 18 .

See also the construction according to the prior art.

Also enclosed by the cover 72 is an electronic locking mechanism for the housing 84, which is intended to ensure that the housing is not disassembled unnoticed and undocumented. Fig. 5 shows a schematic representation of the operation of the pivot lever actuation according to the invention. The actuating lever 16 is shown in block form and is held within the recess 14 by a pin 28 when the linear drive 46 has pushed it into the locking position. The position of the motor or the drive can be checked by a microprocessor MY, which in turn also connects the drive 46 to a battery 54 in order to supply it with a current pulse. A generator G, alternatively a photovoltaic device 5 , or alternatively a transponder device T could be used to charge the battery 54 , if it is an accumulator. The microprocessor MY, in turn, is controlled, for example, by the biometric sensor device 42 , which by means of the thumb through the triggered opening 40 provides signals, and which can be covered by a protective cover means 56, a switch may be actuated by sliding or opening the opening 40 by means of the protective cover means 56, which may trigger the start of operation of the overall arrangement. Alternatively, a keyboard or keypad device 142 , shown here with nine keys, is connected to the microprocessor MY, and a transponder device 242 is also shown, controlled by an external transceiver 243 .

Also indicated is the generation of electrical energy for charging a battery 54 with the aid of a photovoltaic device V. Also shown is an optical sensor device 342 and an interface 86 which works either by means of plug-in devices or preferably by means of an infrared connection 87 in order to connect to a network device 88 . e.g. B. to connect a mobile phone network.
