Description

The invention relates to an actuating handle, for example a door or window handle, according to the preamble of claim 1.

Doors or windows usually have a locking mechanism in order to close building openings in the form of door or window openings against access from outside or against weather influences. The locking mechanism can be actuated from the inside by means of an actuating handle if the locking mechanism is not locked. Often no moveable handles are mounted on the outside of doors or windows, which are directly coupled to the locking mechanism. Door plates with rigid handles or knobs only require the locking mechanism to be unlocked by means of a key inserted in a lock.

Electromechanical door locks are unlocked by motor after a key (mechanical or digital) has been recognized. For example, a key card or a transponder must be held up in front of a reader. So two manipulations are necessary. On the one hand the transponder must be held in front of the reader and on the other hand the door or the window must be opened.

This results in the task of proposing an actuating handle, in particular in the form of a window or door handle, with which the handling effort when unlocking a door lock by means of a transponder is facilitated.

Main features of the invention are set out in the characterizing part of claim 1. Refinements are the subject of claims 2 to 15.

An actuating handle for attachment to an outside of a door is proposed, which has an access control system designed to control a motor lock with an evaluation unit and a reading unit for reading and identifying a transponder that is located in a first detection area defined by the reading unit. The reading unit is integrated in the operating handle. Furthermore, a sensor coupled to the evaluation unit and integrated into the actuating handle is provided for detecting an object, which is located in a second detection area defined by the sensor. The sensor is arranged on a first section and the second detection area extends outward from the first section. The evaluation unit is also designed to activate the sensor for detecting an object in the second detection area after identifying a transponder.

The actuating handle is to be understood as a device that is used to open and close a door or a window. In the sense of this invention, however, the provision of an element to be moved by a user is not necessary. The operating handle could therefore also refer to a rigid, immovable door or window handle.

The access control system is intended to read out and identify a transponder located in the vicinity of the reading unit via the reading unit. This means that it is checked whether the transponder is a transponder previously announced to the system. If such a door is recognized, the door in question can in particular be opened. The actuating handle according to the invention integrates such an access control system in a particularly advantageous manner.

The evaluation unit can be an electronic device which could be designed to receive read data from a transponder and to process it for the purpose of access control. It is coupled to the reading unit in order to receive data read from it. The installation location and the design of the evaluation unit are not of considerable importance for the design of the actuating handle according to the invention. Rather, it is necessary for the evaluation unit to be coupled to the reading unit and the sensor. The evaluation unit can also be integrated in the reading unit or the sensor and fulfill the intended function there.

The reading unit is a device that is capable of reading transponders in a first detection area. Various radio based techniques exist to accomplish this purpose. For this purpose, the reading unit has one or more suitable antennas and a radio circuit connected to them. It is conceivable that the reading unit emits a continuous or clocked radio signal which has a very limited range. This range forms the first detection area around the installation location of the reading unit. If there is a transponder in the first detection area, i.e. the radio range of the reading unit, it can react to the transmitted radio signal. For this purpose, the transponders can be designed to be passive, so that a circuit located therein is supplied with energy by the radio signal and sends a desired data record back to the reading unit. In this case, the first detection area is usually so small that the transponder is practically placed on the reading unit or at least has to approach it very closely. Active transponders are also conceivable that send an identification immediately after receiving a radio signal or respond to a radio signal after actuating an input device, for example a push button. The type and design of the reading unit and suitable transponder are not significant for the execution of the actuating handle. However, it may be appropriate to coordinate the reading unit and the transponders in such a way that a range of several decimeters up to a little more than one meter can be achieved. This allows a user to only carry a transponder with them when they approach the operating handle.

In addition to the reading unit, the sensor is arranged on the actuating handle in such a way that a second detection area is formed which extends outward from the actuating handle. However, the function of the sensor differs significantly from the function of the reading unit and is intended to target an object in the second detection area detect. The second detection area can preferably differ from the first detection area, in particular in the spatial orientation relative to the actuating handle.

The sensor and the second detection area enable the actuation handle to recognize, for example, a gesture of a foot or a hand as a control command. If a transponder is read out and identified in the first detection area and an object or a gesture is subsequently recognized in the second detection area, a door opening signal can be generated. To carry out this process, the evaluation unit is consequently designed to activate the sensor for detecting an object in the second detection area after identifying a transponder.

Consequently, the handle according to the invention forms an extremely convenient way of opening a door or initiating the opening, since it is not necessary to move a door or window handle. It is easy to perform a gesture, especially with a foot. The first detection area can also be selected such that a user carries the transponder in a pocket, for example, and only initiates the opening of the door by a gesture or the like after approaching the operating handle.

In a preferred embodiment, the reading unit is arranged in a first housing and forms a first structural unit. The reading unit can have a large number of individual components, for example a control unit, one or more antennas, signal electronics and the like. The reading unit can be provided as an electronics module, which is arranged, for example, on a circuit board and can be connected to external components via electrical lines. The reading unit can be arranged and encapsulated in the first housing to protect the individual components, to simplify assembly and to increase the robustness. The reading unit then forms a single component that can be integrated on or in the operating handle.

The reading unit is preferably cast in a resin in the first housing. This ensures a particularly high level of robustness against external physical influences and a long service life.

In a preferred embodiment, the reading unit is adapted to a cavity in the actuating handle. The reading unit or the first housing is consequently such dimensioned that it can preferably be completely inserted into the cavity. The adjustment can be made by selecting a cross section that is slightly smaller than the cross section of the cavity. The external appearance of the actuating handle is not disturbed by the integration in the actuating handle and the reading unit is mechanically very well protected.

In an advantageous embodiment, the actuating handle is rod-shaped at least in sections and has a first end and a second end opposite the first end, the first section being located at the first end. The actuating handle can therefore essentially have the shape of a bar handle or bow handle, which extends over a more or less pronounced length on the door. Often these actuation handles are oriented vertically so that a first end can be a lower end of such a bar handle, while the second end is located vertically above. The first section can be arranged at the first end such that the first section and the first end coincide. If the actuating handle is to be arranged vertically, the sensor can be directed downwards. The second detection area can therefore extend to the floor in front of the door. However, if the actuating handle is to be arranged horizontally, for example, the second detection area can also extend transversely to it and be directed towards the floor. However, other variants are also possible in which the second detection area and the orientation of the actuating handle are independent, selectable or adjustable from one another.

The actuating handle preferably has a main extension axis and the second detection area runs parallel to the main extension axis. The sensor is consequently preferably located at one end of the actuating handle and is oriented such that a sensor axis is largely parallel to the main extension axis. An object to be detected is therefore to be passed, in particular at a distance from the end in question, as an extension of the main extension axis.

The sensor could at least partially protrude from the operating handle. For this purpose, the actuating handle in the first section may have a cutout or an opening into which the sensor is fitted. The detection behavior of the sensor can then be determined solely by its design and is one possible installation situation is not limited. By sticking out, cleaning or maintenance can also be simplified.

In an advantageous embodiment, the sensor could be designed as an ultrasonic sensor. Such an emits sound waves in the ultrasound range, which are reflected on objects that are in the second detection range. By determining a transit time of the reflected sound waves, the distance to the object reflecting the sound waves can be determined. In certain installation situations, there may always be a floor or wall surface in the second detection area, which surface always reflects the sound waves when the sensor is activated. The sensor, the evaluation unit or another higher-level component could be designed by adapting a circuit or programming such that this reflection is not interpreted as the object to be detected. If another object is moved into the second detection area, which is then located between the sensor and the wall or floor surface in question, the determined transit times become shorter. This temporary decrease in the runtime should then be interpreted as the object to be recorded.

Instead of an ultrasonic sensor, other variants can also be used. These could include a camera, an infrared sensor, an optical flow sensor, laser scanner or the like.

The actuating handle can furthermore have a lighting unit which emits light in the direction of the second detection region during the detection process. This creates the possibility of signaling to a user that a gesture or the like is expected in the second detection range. This could be initiated if, for example, a known transponder was recognized and the sensor was activated.

The lighting unit is preferably coupled to the sensor. The lighting unit therefore only emits light when the sensor is activated and a corresponding input is awaited.

In a particularly advantageous embodiment, a lens bundles the light emitted by the lighting unit to form a light spot. Bundling can create a light spot that is projected onto a floor or wall surface. A user's attention can be directed to the wall or floor surface by the light spot. The lens can be colored or colorless transparent. It lends itself to having a spot of light generate a diameter of up to 20 cm on the surface in question, which is easily recognizable. The light spot can preferably have a diameter of up to 12 cm. The lighting unit can also be designed so that the light spot can be seen in daylight. It is also advantageous to sharply demarcate the contour of the light spot from the background.

The lighting unit is particularly preferably designed to emit a light cone. The second detection area preferably completely surrounds the light cone.

The sensor and the lighting unit are preferably arranged in a second housing and form a second structural unit. Since the function of the sensor and the lighting unit are coupled to one another in a preferred case, it makes sense to integrate these functions into a single structural unit. The lighting unit can then be coupled directly to the sensor. The second detection area and a light cone emitted by the lighting unit can then be easily adapted to one another. The second structural unit can be completely encapsulated in order to be integrated into the actuating handle in question. This simplifies assembly and reduces the steps required to make electrical contact with the lighting unit.

In an advantageous embodiment, the second housing is also adapted to a cavity of the actuating handle. Depending on the version, this can be a bar handle or a similar device which is not solid, but is designed as a hollow body. Since an integration of the sensor and the lighting unit on the actuating handle is provided, it can make sense to insert these components directly into the cavity. By means of a suitable design of the second housing, this or the second structural unit can be pushed completely into the cavity of the actuating handle in order to fasten it there.

The second housing preferably has a groove for receiving a sealing ring. The groove is preferably circumferential and a sealing ring is to be shaped accordingly. Depending on the design of the operating handle, different shapes for the groove and the sealing ring can of course result.

A projection window can be provided in the second housing. This could then be in the direction of the lens or the light unit and the passage of light rays allow. The projection window can be provided with a specific contour, which influences the contour of the light spot in the desired way.

The sensor can also have a sensor circuit which is designed to recognize a predetermined movement from sensor signals supplied by the sensor and to send a confirmation signal to the evaluation unit when a movement is detected. Depending on the design of the sensor, more or less complex movements can be determined. If the sensor is designed as an ultrasonic sensor, which only makes it possible to determine a distance from an object, a time-limited entry of an object into the second detection area can be detected. This means that the sensor first recognizes no object in a detection period, then detects an object for a certain period of time, after which no object is detected again. This can correspond, for example, to a hand or foot being passed through the second detection area. The sensor circuit is designed to pass on a corresponding signal if such a movement is detected. It is not necessary to forward all measurement data to the evaluation unit without being processed.

In an advantageous embodiment, the reading unit and / or the sensor is / are fastened in a cavity of the actuating handle by clamping or screwing. By clamping, no dedicated fastening devices are necessary and the cross section of the actuation handle can be chosen flexibly in a wide range without requiring a multitude of different designs of the reading unit and / or sensor. A housing surrounding the reading unit or the sensor is preferably clampable. In a particularly advantageous case, the housing in question could have at least one threaded bore into which a screw body is screwed. By turning the screw body so that it is screwed out of the threaded hole, the clear width of the combination of housing and screw body can be increased. If the housing is located together with the screw body inside the actuating handle, this inevitably leads to the housing being jammed. The screw body could be actuated via a through hole which is arranged in the actuating handle. This is preferably arranged on a side that is not visible to the user in the installed state on the door. Such a design for clamping also has the advantage that assembly and removal can be carried out very easily. It could be advisable to provide a type of shoulder or a stop inside the actuating handle, beyond which the housing in question does not enter the cavity can be pushed in. The alignment of the screw body and the through hole can be facilitated. Alternatively, a screw connection, for example with a single screw, would also be conceivable, which extends through a through hole from the outside into the relevant component. It would be advantageous to use a countersunk screw that is flush with the outer surface of the actuating handle.

For haptic feedback when clamping, the first housing could have spring webs on edge or side surfaces which extend outward from the first housing and are compressed when the first housing is clamped. This results in a noticeable pre-tension when screwing. If an available suspension travel is run through completely, the force required for screwing is immediately significantly higher, which is an indication of sufficient clamping. The spring bars can also generate a certain holding force, which counteracts slipping of the through holes relative to the screws when the reading unit is installed in the actuating handle.

In an advantageous embodiment, the actuating handle consequently has through bores for introducing a tool into the cavity for driving screws for clamping or loosening the reading unit and / or the sensor.

The reading unit preferably has an active surface which lies in a cutout of the actuation handle and is flush with an outer surface of the actuation handle. The range and thus the first detection area can be set precisely and implemented without interference.

is a schematic representation of an access control system with reading unit and sensor integrated in the actuating handle.

Fig. 1a shows an outside of a door 2, which is designed as an example of a front door. On this an actuating handle 4 is arranged, which is designed in the form of a rod-shaped handle and is aligned perpendicular to the door 2. The actuating handle 4 has an in Fig. 1b indicated cavity 6, in which a reading unit 8 and a sensor 10 are located.

The reading unit 8 and the sensor 10 are components of an access control system. This is intended to initiate the opening of a motor lock by reading out and identifying transponders and then detecting an object by the sensor 10. For this purpose, the reading unit 8 has a first detection area 12, in which a transponder carried by a user can be read out. The sensor 10 has a second detection area 14, in which the presence of an object can be detected after identification of a transponder authorized for opening. The sensor 10 can be understood in the broadest sense as an input means that can be triggered by a gesture with a foot or hand and is used to actually control the opening of a motor lock.

In the illustration of the actuation handle 4 shown, the second detection area can extend outwards from a first end 16 as the first section of the actuation handle 4. The second detection area concentrates, for example, on an approximately cylindrical, conical or club-shaped area that extends outward from the sensor 10. In this case, the orientation of the sensor 10 becomes an extension direction

18 of the second detection area 14, which for example essentially coincides with a main extension axis 20 of the actuation handle 4. In the illustration shown, the second detection area 14 consequently extends from a lower end of the actuating handle 4 to a floor 22 in front of the door 2. If an object occurs in this second detection area 14, which is shown in a detailed representation in FIG Fig. 1c This is shown by way of example as a foot or shoe 15, this can be recognized by the sensor 10.

In order to intuitively display the second detection area 14 and the activation of the sensor 10 to a user, a lighting unit (not shown here) is available which projects a light spot 24 onto the floor 22. The configurations of the above-mentioned components are explained in more detail with reference to the subsequent figures.

Fig. 2 shows a section of the operating handle 4, in which the reading unit 8 is integrated. As an example, the actuating handle 4 has a cross section which is curved on one side but is flattened on the other side. The curved side can face the door 2 in an installed state, while the flattened side 28 then points away from the door 2. Of course, it would also be possible to design the actuating handle 4 with a different cross section.

It can be seen in this illustration that the reading unit 8 is integrated in the actuating handle 4 in the form of a closed structural unit, which is referred to below as the first structural unit 30. This first structural unit 30 has a first housing 32 which surrounds the reading unit 8. At two ends 34 and 36, threaded bores 38 are provided, into which screws 40 are screwed. In addition to this, the actuating handle 4 has on its curved side 26 through bores 42 positioned in alignment with the threaded bores 38, through which a user can insert a tool for turning the screws 40. If the screws 40 are unscrewed from the respective threaded bore 38, they abut on the inside of the actuating handle 4 and consequently jam the first housing 32 in the cavity 6. This not only ensures secure attachment of the reading unit 8, but also a simple disassembly option.

Fig. 3a shows the first assembly 30 in an enlarged view. It can be seen here that the first housing 32 is dimensioned significantly larger than is necessary for the actual accommodation of the reading unit 8. Electrical connection lines 44 are shown that are made of the inside of the first housing 32 to the outside. As an example, there are notches 46 for inserting the connecting lines 44 and a clip 48 which can be inserted into the first housing 32 for fixing the connecting lines 44 to the first housing 32. The first is provided for sealing the reading unit 8 and for encapsulating the entire first unit 30 Fill housing 32 with a potting resin. As a result, the reading unit 8 is irreversibly completely surrounded by a waterproof cover and is robustly protected against external mechanical influences. In the process of pouring out the first housing 32, the clamp 48 serves to seal the first housing 32. The first housing 32 can essentially have a trough shape in which one side is open and all other sides are closed or closable.

The reading unit 8 may have a dedicated, active surface 50 which is shown in FIG Fig. 3b is shown on a lid, which should not be covered when integrated into the actuating handle, in order to maintain a sufficient range. The active surface 50, which could also be called the visible surface, protrudes from the first housing 32. It is advantageous if the active surface 50 lies in a corresponding section of the actuating handle 4.

Fig. 4a shows a portion of the operating handle 4 in a three-dimensional representation. In particular, a section 52 can be seen here, which penetrates the actuating handle 4 on its flattened side 28. The active surface 50 of the reading unit 8 can be introduced into the rear of the latter. It should be noted at this point that the active surface 50 is preferably arranged on the first structural unit 30 in such a way that the flattened side 28 and the active surface 50 are arranged flush with one another and are flush with the surface. This enables a harmonious surface design to be achieved, which does not interfere with the high-quality appearance of the actuating handle 4.

Provision can also be made to provide an additional sealing ring 54 between the active surface 50 and the cutout 52. This could be configured in such a way that the part of the sealing ring 54 visible on the cutout 52 is narrower than in the interior of the cavity 6, so that the latter presses against the cutout 52 from the inside when the first assembly 30 is clamped, but does not penetrate through the configuration can and thus achieve a flush appearance with the sealing ring 54.

As already explained above, the actuating handle 4 can have different shapes, which are shown in FIGS Figures 4b and 4c being represented. Fig. 4b shows an actuating handle 4 with a substantially square cross section. Fig. 4c shows a classic, completely cylindrical cross-section, as is often used with bar handles. During the active area 50 of the variants Figures 4a and 4b can be designed in the same way, with the variant in Fig. 4c a curved version of the active surface 50 is used.

The Figures 5a and 5b show a second structural unit 56 which is to be positioned at the first end 16 of the actuating handle 4 and has the sensor 10 arranged therein. A second housing 58 is provided here, which is adapted to the cavity 6 of the actuating handle 4. It can therefore be inserted into the actuation handle 4 through an opening in the first end 16. A threaded bore 60 is also provided here for fastening, in which a screw 62 is arranged. This is an example of a countersunk screw. As a result, the second housing 58 and consequently the second structural unit 56 can also be fastened in the cavity 6 of the actuating handle 4.

To seal the transition between an inner wall of the actuating handle 4 and the second structural unit 56, the second housing 58 has a circumferential groove 64 into which a suitably shaped sealing ring is inserted. When designing the groove 64 and the sealing ring, care should be taken that the sealing ring is held so securely by the groove 64 that detachment or shearing off is prevented when the second structural unit 56 is inserted into the cavity 6. In Fig. 5b A sealing ring 66 is shown, which is held completely in the groove 64 and is supported on the inside of the cavity 6.

In addition, in the Figures 6a and 6b the second assembly 56 is illustrated in an exploded view with the separate second housing 58. The second housing 58 has a first receiving space 68, which is designed to receive the sensor 10. This is arranged, for example, on a circuit board 70, which has a sensor evaluation circuit, for example. In addition, a lighting unit 72 is shown in dashed lines, which is likewise located on the circuit board 70 by way of example and is arranged next to the sensor 10. This lighting unit 72 can be electrically coupled to the sensor 10 or the circuit board 70, so that when the sensor 10 is activated, the lighting unit 72 is also in operation and emits light.

A lens 74 is provided for focusing the light and can be inserted into a second receiving space 76. This is placed next to the first receiving space 68 in the second housing 58. If the sensor 10 and the lens 74 are introduced into the associated receiving spaces 68 and 76, the circuit board 70 lies flush on the second housing 58. The lighting unit 72 can be implemented as a light-emitting diode soldered onto the circuit board 70, to which a first lens 73 is already connected. For example, this can be arranged on the circuit board 70 via a carrier 78. The lens 74, the carrier 78 and the first lens 72 can be preassembled via a tube 79.

As an example, an electrical connector 80 is placed on the circuit board 70 on a side facing away from the sensor 10 and the lighting unit 72. The connector 80 allows coupling to a higher-level system. It is conceivable that the circuit board 70 has a sensor evaluation circuit which controls the sensor 10 and the lighting unit 72 and in particular evaluates signals or data provided by the sensor 10. The sensor evaluation circuit is preferably designed to detect an object located in the second detection area from the raw signals. A signal can then be provided via the electrical connector 80 that a corresponding object has been detected. It is then not necessary to send all signals from sensor 10 to a higher-level unit in order to carry out the processing there.

The Figures 7a, 7b and 7c also show a greatly simplified structure of an access control system 82, which is formed by the reading unit 8, the sensor 10 and an evaluation unit 84. The evaluation unit 84 is connected to the reading unit 8 or forms part of it. It can compare the read-in data of a transponder, for example, with data from a stored data record of access-authorized transponders and recognize whether the transponder located in the first detection area is an access-authorized transponder.

If an authorized transponder is recognized, the evaluation unit 84 can activate the sensor 10 for detecting an object in the second detection area. The latter can, for example, send a signal of such a detection to the evaluation unit 84 or transmit raw data or raw signals for evaluation in the evaluation unit 84.

The connection between the sensor 10 and the evaluation unit 84 can be made directly or via a serial line via the reading unit 8. A wired connection is conceivable. Alternatively, a wireless connection would also be conceivable. If a wireless connection is being considered, the evaluation unit 84 and the sensor are to be equipped with corresponding connection devices, for example a transmitting and receiving unit in each case.

To provide electrical power, the sensor 10 can be supplied via a long-term battery or an electrical line.

The reading unit 8 can also be connected directly or indirectly to the evaluation unit 84. In the reading unit, however, the power supply can preferably take place via electrical lines. Corresponding connection devices, for example one transmitting and receiving unit each, must also be provided here in the case of a wireless connection.

The invention is not limited to one of the above-described embodiments, but can be modified in many ways.

All of the features and advantages arising from the claims, the description and the drawing, including constructive details, spatial arrangements and method steps, can be essential to the invention both individually and in the most varied of combinations. <b> List of reference symbols </b> 2nd door 44 electrical connection cable 4th Operating handle 46 score 6 cavity 48 Bracket 8th Reading unit 50 active area 10th sensor 52 Neckline 12th first detection area 54 Sealing ring 14 second detection area 56 second unit 15 object 58 second housing 16 first end / first section 60 Tapped hole 18th Extension direction of the second detection area 62 Grub screw 64 Groove 20th Main extension axis 66 Sealing ring 22 ground 68 first recording room 24th Spot of light 70 circuit board 26 curved side 72 Light unit 28 flattened side 73 first lens 30th first unit 74 lens 32 first housing 76 second recording room 34 End of the first housing 78 carrier 36 End of the first housing 79 Tube 37 Spring bar 80 electrical connector 38 Tapped hole 82 Access control system 40 screw 84 Evaluation unit 42 Through hole
