The housing has a partially spherical bearing surface with a cylindrical bore hole proceeding from it, wherein a partial ball with a first bearing for a closure drive shaft extending through the cylindrical bore hole and with a second bearing for the actuation lever is arranged in the cylindrical bore hole, and the two bearings enable a rotation of the partial ball in relation to the housing and a swiveling of the actuation lever in relation to the partial ball around an axis vertical to the closure drive shaft and to the extension of the lever.

Description

Electrically lockable swivel lever operation

Background of the Invention

The invention relates to an electrically lockable swivel lever operation, consisting of a trough which can be placed on a door leaf or the like, in which an operating lever for a fastener, such as a cam lock or rod fastener, is mounted such that it swings out of the trough in the position in which it enables a lock actuation, can be brought into a position pivoted into the trough, in which it does not enable a lock actuation and in which it can be locked by an electromechanical locking device.

Brief description of the state of the art

Such a pivot lever operation is already known, see for. B. EP 0 824 624 B1. The known swivel lever actuation requires a special arrangement on the door frame so that it works correctly. This is too complex for many applications.

Object of the invention

The object of the invention is to modify the electrically lockable pivot lever actuation of the type mentioned in such a way that it is simple in construction and in particular does not require any special devices which are constructed on the door frame or the like instead of on the door leaf or the like.

In particular, the arrangement should be designed so that it can be used with essentially conventional pivot lever locks.

Another task is to make the key for a cylinder lock or the like that has been used up to now, even in the state of the art, unnecessary. solutions

The object is achieved in that the electromechanical locking device is a unit which can be inserted or integrated into the trough and from which a pin or projection for locking the actuating lever can be extended or swung out by means of an electrical control signal.

These features ensure that, on the one hand, the pivot lever actuation according to the invention can be equipped with previously used pivot lever actuations without electrical locking, for example by the fact that this assembly can be used in conventional actuating levers - possibly with minor processing - and on the other hand there is the possibility of previous pivot lever actuations simply by switching to the version according to the invention.

The provided electrical locking means that the cylinder with the associated cylinder key previously used in the prior art can be dispensed with, which has the advantage that a key that was previously necessary is no longer required, and therefore cannot be lost or fall into the wrong hands ,

It is particularly expedient if, according to a further development, the handle has an opening on its top in the area of the structural unit, through which the structural unit inserted in the trough is accessible when the actuating lever is pivoted in. This has the advantage that no electrical connection to the actuating lever has to be created, so that the construction can be simplified and made more reliable.

In particular, there is no need for flexibly laid cables and plug contact constructions, which are very susceptible to faults.

There are several ways to access the assembly. A particularly favorable embodiment results when the opening has the size and shape of a fingerprint, and if the accessible surface of the assembly has a fingerprint sensor surface (also referred to as a biometric sensor device). This configuration gives the possibility, using the thumb of an operator, which is placed on the opening of the actuating lever and thereby touches the fingerprint sensor surface of the assembly, by means of corresponding electronic devices within the assembly to analyze its fingerprint lines in order to determine whether the person belonging to the fingerprint enjoys access authorization to the control cabinet. If this is the case, the module can react so that it outputs a control signal for driving its projection or pin and swivels it in or retracts and thereby opens the lock, whereupon the operator can then swivel out the actuating lever and open the lock.

Another possibility is to design the opening in the actuating lever in such a way that light (be it visible or invisible) can pass through, and if an optical sensor surface is applied to the surface of the unit that is accessible to the light and that reacts in a certain way to the light signal , provided that the light has a temporal or local modulation (pattern), which may represent an identifier which signals the electromechanical locking device connected downstream of the sensor surface, 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 the assembly that is accessible through the opening. Then, with the help of, for example, a simple pen or with a pointed finger, the keyboard can be operated and a z. B. coded message can be entered, which in turn can serve to unlock the locking device.

Yet another alternative is to access a key actuation arranged in the structural unit through this opening, which can be in the form of the previous cylinder key arrangement, but is not stored in the handle here, as in the prior art, but instead in that of the hollow worn unit. The operating lever is therefore slimmer and easier to handle.

The key in turn enables a pulse or other generation of a signal, which in turn leads to the fact that the locking device is electrically unlocked in the manner already described.

If one installs a transponder device in the unit, it may even be possible to dispense with the opening in the hand lever, since the electromagnetic wave, by means of which the transponder device can be actuated, by the material of a hand lever, if it is e.g. B. consists of plastic, can penetrate without major problems.

The transponder device has the further advantage that it can absorb energy from the external device, for example to trigger the opening process with this energy without z. B. battery devices should be available.

Another possibility of dispensing with a battery or simplifying its charging can be achieved by providing a photovoltaic arrangement in the area of the opening on the structural unit, the opening making this device accessible to the outside light.

In order to facilitate the recognition processes, in particular at higher security levels, it is advantageous if the structural unit comprises a microprocessor chip which can carry out sufficiently complicated calculation processes to enable high levels of security, for example when entering codes or when fingerprint scanning.

The chip has the further advantage that a configuration is possible in which the overall arrangement is connected to a network, for example to an internal network, which reports the state of the closure to a remote control center. Conversely, the remote control center can also unlock the Closure are 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 can be implemented by wiring or advantageously by a wireless connection, such as an infrared interface, to which, for example, a mobile phone provided with a corresponding counter interface can be connected.

According to yet another development of the invention, the operating lever can carry a displaceable or pivotable cover for the opening on its upper side. This makes it possible to protect the device, such as the sensor device, arranged under this breakthrough from damage and contamination.

It has been found to be particularly advantageous mechanically if the structural unit comprises a cup-shaped housing, the bottom of which has a receiving space that is accessible from the outside for sensor devices or the like that can be accessed through the opening in the hand lever. If the assembly comprises a cup-shaped housing, it is advantageous if the side wall has an opening for the passage of the locking pin or projection. Such a unit with a cup-shaped housing preferably has a flange-like edge, which edge has bores for the passage of clamping screws with which the cup (together with, for example, a cover) can be accommodated and fixed in a corresponding recess area of the trough. The fastening screws could at the same time serve to clamp the trough within a door leaf or the like.

It has proven to be expedient if the structural unit comprises an electric motor drive which, when actuated, alternately extends or retracts the locking pin or the locking projection. An actuation pulse can, for example, cause the locking pin or locking projection to extend and lock the pivoted-in lever in the recess, while another pulse then leads to the pin or the projection being retracted, 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 turn off power consuming circuit areas after a certain idle time. As soon as any trigger signal arrives from the sensor surface, the microprocessor switches the power supply on again immediately. In this way, a possibly provided in the device (rechargeable electricity energy storage) battery is protected.

Switching on can take place, for example, by pushing an existing cover slide or the like away, so that the sensor surface is hit by light, for example. Alternatively, however, the slide itself can also have a contact which, when actuated, supplies a pulse to the microelectronic device in order to then start it up.

In this way it is possible to operate the assembly unexpectedly for months, i.e. That is, long operating times can be bridged with a battery or a battery charge.

The swivel lever actuation according to the invention can be used with very different locks, for example with cam locks, with rod locks, etc.

Best ways of carrying out the invention

1A shows an electrically lockable pivot lever actuation 10, consisting of a trough 14 which can be placed on a door leaf 12 or the like and in which an actuation lever 16 is mounted such that it can be swiveled out of the trough from a position, see the pivoting axis 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 mounted flat bars 24 are pushed outwards, in which pushing out in a known manner, see the prior art, a door leaf, for example, in one Frame is unlocked. 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 a unit 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 a shoulder or an intermediate wall 34 which is formed by the bottom and side walls 36 of the actuating lever 16 which form a trough, see FIG. 3 , are formed. 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 picked up, 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 has the shape of the fingertip of a thumb or index finger with bevels 50, 52 adapted to it, 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.

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 certain local fluctuation or pattern (locally modulated light) or pulsed light of certain coding (temporally modulated light), a sensor output signal can also be generated, which, when processed, leads to an opening of the locking device. In the case of pulsed light, scattering effects 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 a key must be kept that can be lost. B. connected to a cylinder that takes up a relatively large amount of space.

The surface 42 can also be a so-called transponder, which I have a coil that a second near the operating lever 16th passed coil absorbs energy, for example, to supply the linear motor 28 for displacing the pin 30 with energy, and at the same time also transmit digital information which indicates, for example, 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 control cabinet was opened could be logged.

Such a transponder 111 can also be installed on a key 110, as shown in FIG. Plastic 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 power 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 cooperate with a contact which can be triggered by a magnetic field, such as Riedkontakt, which is located in a transponder reader arranged in the electrically lockable swivel lever actuation, such that when the magnet approaches the contact switches on the voltage 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, so that this device, which includes photodiodes for example, due to the striking Light can generate energy.

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, 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, the edge of which 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 62 of the trough 14, see FIG. 2, can be determined in that, after placing a cover 72 with corresponding bores 74, cap screws can be inserted through these bores 74, 68, and the bores 78, 76, which on the one hand press the cup with its annular shoulder 77 onto the flange 66 of the cup 60 , on the other hand, the door leaf is clamped between itself and the trough 14 with an edge 79, so that the entire arrangement is held in a clamped manner at this point. Dashed lines, see Fig. 1A, shows that the other end of the trough 14 can also be clamped in a similar manner by providing a lock case or gearbox 80 in such a way that the thin wall 12 is also there with the help of screws 170 the trough 14 on the one hand and the box 80 on the other hand is clamped. Box 80 also shows dashed lines protruding locking rods 24 and a closure drive shaft 82, which is connected on the one hand to a pinion arranged within the housing 80, not shown, on the other hand supports the pivot lever 16 at its free end by means of the pin axis 18.

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. 5 shows a schematic representation of the mode of 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 S, 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 Opening 40 triggers signals and which can be covered by a protective cover device 56, a switch which may trigger the start of operation of the overall arrangement may be actuated by sliding or opening the opening 40 by means of the protective cover device 56. 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. z.
