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.

The object of the present invention is to propose an actuating handle, in particular in the form of a window or door handle, which has an alternative and flexible structure and which enables a door lock to be unlocked by means of a transponder.

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 fastening to a door is proposed, comprising an access control system designed to control a motor lock or a clutch with an evaluation unit and a reading unit for reading and identifying a transponder that is located in a detection area defined by the reading unit. The actuating handle has a modular functional assembly with a carrier which has a plurality of receiving sections for receiving at least one bearing device for storing a grip part, at least one cladding element and the reading unit.

The actuating handle is to be understood as a device that is used to open and close a door or a window. For the purposes of this invention, this relates to an element to be moved by a user in combination with a reading unit which can be used to unlock a motor lock or a coupling which can establish or separate a connection to a door lock mechanism. The actuating handle could therefore refer in particular to a movable 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, in particular opening of the relevant door or unlocking of a motor lock located therein or the establishment of a connection with a door lock mechanism can be initiated. 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 that the evaluation unit is coupled to the reading unit. The evaluation unit can also be integrated in the reading unit and fulfill the intended function there.

The reading unit is a device that is able to read transponders in the 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 detection area around the installation location of the reading unit. If there is a transponder in the 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 detection range 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.

If a transponder is read out and identified in the detection area, a door opening signal can be generated. This can be sent to a motor lock, which is located in the door. The motor lock can be activated for unlocking. In particular, this can mean withdrawing a bolt. Alternatively or in addition, the retraction of a trap. Depending on the design of the motor lock, the handle part can also be actively coupled or uncoupled to a component of the motor lock, for example for pulling back the latch. This can therefore be a controllable clutch.

The carrier of the modular functional assembly can be understood as a mechanical basis that can accommodate different modules and combines their functions with one another in the form of the compact functional assembly. To accommodate the various modules the carrier has at least one receiving section which is matched to at least one module to be received and is positioned accordingly. The receiving sections can be realized in the form of depressions, recesses, projections, webs, flanges, bores or similar shape features. Depending on requirements, different reading units or storage facilities can be provided, which can be selected according to customer requirements, country-specific preferences or security levels or motor locks used.

The carrier can be attached directly to the door using a cover, an adapter plate or the like. The cladding element preferably covers the carrier and all modules located on it in order to achieve a shapely outer shape of the actuating handle. By using the carrier and a covering element covering the carrier, the shape of the actuating handle is not directly dependent on the size and design of the individual components. Consequently, the actuating handle according to the invention forms a flexible possibility for equipping a door in order to allow it to be opened comfortably.

In an advantageous embodiment, the carrier has a first cutout for the passage of a drive pin, which can be connected to the handle part. The first cutout allows a drive pin connected or connectable to the handle part to be passed through from one side through the carrier. The carrier is therefore able, for example, to arrange the bearing device on one side, while on an opposite side of the carrier a drive pin can be guided to a side facing away from the handle part. A motor lock or just a controllable clutch could be arranged there, with an input for a drive pin. Depending on the structure and arrangement of the individual components, a return spring or the like could also be present, which can be connected to the drive pin.

The bearing device preferably has a bearing frame on which a pin bearing is arranged on at least one side, which extends outward from the bearing frame and in which a first drive pin can be connected to the pin bearing in a tensile manner. The bearing frame can be connected to the carrier in such a way that the bearing axis, ie the central axis of the pin bearing, coincides with the central axis of the first cutout. The first drive pin can be connected to the pin bearing in such a way that it cannot be released from the pin bearing by applying a tensile force. It can also be provided that a handle part as well is tensile attached to the first drive pin. The first drive pin can be designed as a polygon, in particular as a square, as in conventional drive pins of an actuating handle. By attaching the handle part, it can consequently be mounted by means of the pin bearing and conduct torque in the direction of the carrier. In a special case, the rear of the pin bearing could have a coupling section which is designed to receive a further drive pin. As an alternative to this, it would be conceivable to design the first drive pin in such a way that it extends completely through the actuating handle and can be connected outside of it with a motor lock or a coupling which can be coupled to a door lock mechanism.

In a preferred embodiment, the bearing frame is designed as a sheet metal that has been folded multiple times, the first receiving section of the carrier being designed correspondingly to receive the bearing frame flush with the surface. The first receiving section could, in particular, be designed as a projection which, at least in some areas, has a circumferential surface which is adapted to an inner contour of the bearing frame. The circumferential surface could also be penetrated by resilient elements which deflect when the bearing frame is pushed on or plugged on and thereby apply a prestress to an inner surface of the bearing frame. However, it would also be conceivable for the bearing frame to have an undercut, at least in some areas, which correspond to recesses in a lateral surface or circumferential surface of the projection, so that they snap into or slide into the bearing frame after the latter. In this way, at least a temporary mounting of the bearing frame on the carrier can take place. A final attachment could be done with separate, dedicated screws. Alternatively, screws can be used which, after all components of the actuating handle according to the invention have been plugged together, clamp or hold them together.

In an advantageous embodiment, the first receiving section is designed as a projection and the bearing frame at least partially surrounds the first receiving section. As a result, the bearing frame can nestle well against the projection and forms a mechanically robust arrangement in the region of the first receiving section.

The pin bearing may have a radially around the central axis, at least partially cylindrical surface, which extends from the bearing frame in the direction of the handle part. The actual bearing can be arranged within this section, so that the entire Bearing frame can be made from a single sheet and at the same time an elegant finish is visible to the user. The separate production and arrangement of a pin bearing and its attachment in the bearing frame can be saved. The necessary variety of parts is reduced and assembly is made easier.

The reading unit can be arranged on a side of the carrier facing away from the handle part. As a result, it faces away from the operating side of the actuating handle and is consequently protected between the carrier and the door to which the actuating handle is finally attached. Additional encapsulation of the reading unit is therefore not necessary if the support is dimensioned to be sufficiently robust. This is particularly the case if the actuating handle according to the invention is attached to an inside of the door and a particularly watertight design is not required.

The reading unit is preferably arranged on the carrier above the first section. In the case of reading units which have a shorter range, a marking could be arranged on the side facing the user, to which the transponder is to be held. When the reading unit is arranged above the first section, the area facing the user and the installation location of the reading unit almost coincide.

In an advantageous embodiment, the actuating handle has an optical indication device which is coupled to the reading unit and / or the evaluation unit and is designed to emit an optical indication when reading in and / or during identification. In particular, this could be arranged together with the reading unit on a common board and directed towards the handle part. A light signal can be emitted when an authorized transponder is identified. If the reading unit is located above the first section, the light signal emitted can consequently emerge from the actuating handle on a side facing the user above the handle part and give the user immediate feedback that a transponder is being identified.

The at least one cladding element preferably has a first cladding element which completely surrounds a surface facing the handle part. The first cladding element can thus act as a mechanical termination of the actuating handle.

The first cladding element could be formed from a metallic material and have a window arranged above the bearing device. The metallic design increases the mechanical robustness against impacts and other accidental or deliberate influences. The detection area of the reading unit is not shielded by the window, at least in a direction facing the user.

In an advantageous embodiment, the at least one cladding element has a second cladding element which is at least partially formed from a plastic and is arranged on a side of the first cladding element facing the handle part. The plastic version can be used to cover the window without affecting the detection area at least in the direction facing the user.

The carrier is preferably made of a plastic. Injection molding can be used to inexpensively produce a complex structure of virtually any shape that is suitable for realizing the receiving sections.

To return the handle part from an actuated position to a neutral position, a return spring unit can be arranged on a side of the carrier facing away from the handle part. The return spring unit can be implemented in the form of a compact package, which can be arranged as a module on the carrier.

A cover is preferably arranged on a side of the carrier facing away from the handle part as the outermost component and completely closes the carrier. The operating handle can thus be screwed directly onto the door as a complete unit.

Furthermore, the cover can have at least one threaded bore for receiving a screw which is inserted through the carrier and at least one component facing the handle part. The at least one component can be any of the aforementioned modules, which can include the storage device, the reading unit, the return spring unit or other. The components can be held together by the continuous screw.

Further features, details and advantages of the invention emerge from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. Show it:

Fig. 1 shows an actuating handle 2 according to the invention in an exploded view. The actuating handle 2 is provided in particular for arrangement on an inside of a door or an inside door. For operation, a handle part 4 is provided, which is exemplarily rectangular and can be operated like a conventional door handle.

The actuating handle 2 has a modular structure, a carrier 6 being used as the core component. This can consist, for example, of a plastic and is intended to accommodate various other components, so that a modular functional assembly is formed from these. The carrier 6 has a first cutout 7 through which a drive pin can extend.

First, a bearing device 8 is provided, which has a bearing frame 10 on which a pin bearing 12 is provided for storing a first drive pin 14. The bearing frame 10 can be based on a sheet which is folded several times. When folding, two side tabs 16 are formed, which run essentially parallel to each other. A bottom flap 18 is provided on an underside and extends essentially between the two side flaps perpendicular to the side flaps 16. The tabs 16 and 18 do not have to be connected to one another.

A first receiving section 20 of the carrier 6 is designed as a projection with two side surfaces 22, which are designed to correspond to the side flaps 16. The bearing frame 10 can consequently be placed on the first receiving section 20, so that the two side tabs 16 are pushed or placed on the two side surfaces 22 of the carrier 6. By means of a corresponding design, for example with an undercut, resilient elements or other features, one can at least Temporary positive or non-positive connection between the bearing frame 10 and the carrier 6 are made.

The pin bearing 12 extends outward from the bearing frame 10. It has a cylindrical surface 26 which extends radially around a central axis 24 and extends from the bearing frame 10 in the direction of the handle part 4. The pin bearing 12 is limited, for example, by the cylindrical surface 26 or formed thereby. A corresponding roller bearing having a cylindrical outer surface can be introduced and fastened into the cavity enclosed by the cylindrical surface 26. By appropriate means, which are not shown here, the first drive pin 14 can be held axially immovable on the pin bearing 12.

A second receiving section 28 in the form of a recess is provided on a side of the carrier 6 opposite the bearing device. The second receiving section 28 can receive a reading unit 30 which is arranged above the central axis 24 and in particular above the first section 7. The reading unit 30 then lies above the bearing device 8 and in a side of the carrier 6 facing away from it.

The reading unit 30 is a component of an access control system. This is intended to initiate the opening of a motor lock or a coupling, which is coupled to a door lock mechanism, by reading and identifying transponders. For this purpose, the reading unit 30 has a detection area in which a transponder carried by a user can be read out. By arranging the reading unit 30 on a side of the carrier 6 facing away from the handle part 4 and the bearing device 8, protection of the reading unit 30 against mechanical damage can be achieved. The reading unit 30 can have an electrical connection line 32, which can be connected, for example, to a motor lock (not shown here) or the corresponding coupling. As a result, the reading unit 30 can be supplied with electrical voltage and also initiate the opening or unlocking of the motor lock. As explained further below, the reading unit 30 can have or be connected to an evaluation unit which could be located outside the actuation handle 2.

A return spring unit 34 is provided to enable the handle part 4 to move normally. This has, in particular, a spring assembly, not shown here, which counteracts a rotation of the first drive pin 14 driven by the handle part 4.

Return spring unit 34 may be connected to a second drive pin (not shown). However, the first drive pin 14 can also be designed such that it extends into the return spring unit 34 or beyond. The detailed design can be chosen freely according to standard standards. For this purpose, it is also conceivable that the bearing device 8 has a coupling for coupling to the first drive pin 14 on a side facing away from the handle part 4. Finally, the first drive pin 14 or a second drive pin should provide a connection to a motor lock (not shown here) or a latch mechanism.

On a side of the carrier 6 facing the handle part 4, a first cladding element 36 is provided, which is formed, for example, from a metallic material. In order to ensure an optimal detection area for the reading unit 30, the first cladding element 36 has a window 38 on a side lying above the central axis 24. This represents an opening that is aligned with the orientation of the reading unit 30. Overall, the first cladding element 36 is trough-shaped, so that the carrier 6 with the bearing device 8 arranged thereon is completely enclosed and covered to the outside. Of course, a second cutout 40 is provided for this purpose, through which the pin bearing 12 extends outwards. In the area of the window 38, the frame 6 and the first cladding element 36 are wedge-shaped.

A second cladding element 42 is provided for optically complete coverage, which is formed in particular from a plastic. The radio signal between a transponder and the reading unit 30 is not disturbed by the plastic. The second cladding element 42 is arranged on a side of the first cladding element 36 facing the grip part 4 and has a third cutout 44 through which the pin bearing 12 can extend outwards. In addition, a rosette 45 can be provided to cover the pin bearing 12. This can be followed by a tolerance sleeve 47 through which the grip part 4 can be guided.

Finally, a cover 46 is provided on a rear side of the actuating handle 2, the extent of which coincides with the area of the carrier 6. Several threaded bores 48 are arranged here, which can accommodate screws (not shown here). These screws can extend through bores 50 in the bearing device 8, bores 52 in the carrier 6 and bores 54 in the return spring unit 34 and can be screwed into the threaded bores 48. This will make everyone Components firmly connected to each other. An opening 56 is provided for the connecting line 32, which is formed, for example, as a notch. This adjoins a fourth section 58.

Fig. 2 shows the actuating handle 2 in an assembly. It can be seen here that the pin bearing 12 protrudes from the second cladding element 42 and the grip part 4 comes to rest flush against it. It is conceivable that the actuation handle is coupled in combination with another actuation handle on the other side of a door. The reading unit 30 could therefore also be used for both sides.

Fig. 3 shows an access control system 60 in a very simplified, schematic representation. A reading unit 30 is shown here, which is connected to an evaluation unit 62. The evaluation unit 62 could be designed to compare read data from a transponder with known data and to identify whether an authorized transponder is within the detection range of the reading unit 30. The evaluation unit 62 can also be integrated in the reading unit 30. It would also be conceivable to connect the evaluation unit 62 to a further reading unit which is located at a different location on the door or entirely outside.

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 Operating handle 36 first cladding element 4th Handle part 38 window 6 carrier 40 second section 7 first section 42 second cladding element 8th Storage facility 44 third section 10th Bearing frame 45 rosette 12th Pin bearing 46 cover 14 first drive pin 47 Tolerance sleeve 16 Side tab 48 Tapped hole 18th Bottom flap 50 drilling 20th first recording section 52 drilling 22 Side surface 54 drilling 24th Central axis 56 score 26 cylindrical surface 58 fourth section 28 second receiving section 60 Access control system 30th Reading unit 62 Evaluation unit 32 electrical connection cable 34 Return spring unit
