Definitions

  • the invention relates to a door handle according to the preamble of patent claim 1.
  • Door handles for actuating an opening and/or closing mechanism of a door are known in a wide variety of design variants. These are part of a door fitting and are used in particular to open and/or close the locking mechanism of doors or similar components.
  • Such door handles usually have at least one handle, which is preferably non-rotatably connected via a driver element, in particular an actuating polygon or a rod-shaped square pin, also referred to as a square shaft, for rotary entrainment of an actuating and/or locking device accommodated in the leaf of a door.
  • a handle is usually provided at both ends of the driver element, with at least one of the handles preferably being arranged detachably on it for assembly reasons.
  • the opening and/or closing mechanism accommodated in the wing of the door is usually formed by a so-called case lock comprising, inter alia, at least one latch accommodated in an elongate housing and a bolt, which are also referred to as mortise locks. These are inserted into a correspondingly shaped recess in the door leaf or door leaf, which is standardized in Europe, and are fastened there in such a way that their end face is approximately flush with the narrow side of the door leaf or door leaf that is exposed when opening.
  • the latch engages in a lock plate arranged in the door frame and located opposite the box lock.
  • the case of the box lock is pulled back from the lock plate when the handle is actuated.
  • the handle is pressed downwards and, via the pivoting movement of the handle thus generated, a rotary movement is initiated in the driver element, which is correspondingly rotated about its axis of rotation.
  • the turning or rotational movement of the driver element is a in the box lock rotatably mounted coupling means, such as a nut in a return movement case implemented.
  • the connection between the latch and the lock plate is released and the door leaf released, ie the door can be opened.
  • Electromechanical locking systems in particular locking cylinders with an electric motor drive unit, have also become known in the recent past, in which, instead of a conventional key, the lock can be opened and/or locked using an electronic key, for example by entering a password or transmitting an identifier using the electric motor Drive unit takes place.
  • the disadvantage is that the lock is opened and/or locked via a lock cylinder, which is known per se and is actuated by the electromotive drive unit, i.e. the lock cylinder is actuated manually by inserting the key and turning it in the lock replaced by an actuating movement generated by the electromotive drive unit.
  • a further disadvantage here is to provide a locking cylinder in the lock in addition to the electromechanical components.
  • an "electronic" door handle which has an electromechanical clutch for producing a non-rotatable connection between a door-side output shaft and a handle facing away from the door leaf shortened driver element in the form of an actuating polygon.
  • the locking mechanism is released without the use of a locking cylinder by appropriate activation of the electromechanical clutch, and this can be used to mechanically decouple the handle from the output shaft in such a way that actuating the handle does not actuate the
  • the electromechanical clutch has a large number of drive and clutch components which are operatively connected to an associated electromechanical drive unit ng can be brought and actuated by an electric motor drive.
  • the clutch movement takes place along the axis of rotation or rotation of the output shaft.
  • the coupling mechanism extends over the entire neck section of the handle into the adjoining rosette of the door handle, with the free end of the actuating polygon being mounted in the rosette via the drive shaft.
  • the essential aspect of the door handle according to the invention can be seen in the fact that the electromechanical coupling device is accommodated in the handle section of the handle and that the at least one coupling element for producing the non-rotatable operative connection with the driver element can be displaced radially to the axis of rotation by a motor.
  • the electromechanical clutch device is particularly advantageously fully integrated in the pusher section of the handle and the non-rotatable operative connection between the driver element and the handle is established by means of a clutch movement along a movement direction running radially to the axis of rotation.
  • the inventors have recognized that an arrangement of the coupling point in the intersection of the pivoting and rotation axis of the door handle and the longitudinal axis of the handle ensures an extremely reliable and furthermore axially stable connection between the driver element and the handle.
  • Such "electronic" door handles can advantageously be used to control access to rooms and sections of buildings.
  • the electromechanical clutch device can advantageously be transferred from a coupled state to a decoupled state and vice versa.
  • the driver element and the at least one handle are particularly advantageously connected to one another in a rotationally fixed manner, whereas in the decoupled state the at least one handle can be freely pivoted about the pivot or rotation axis.
  • the handle in the decoupled state, the handle can still be pivoted about the axis of rotation, but without this triggering an actuation of the door lock, in particular a return movement of the latch.
  • the coupling element and an electric motor drive unit are arranged one behind the other along the longitudinal axis of the handle and are accommodated in the handle section of the handle.
  • an electronically controllable actuator unit or a corresponding control element can also be used.
  • the electromechanical clutch device preferably has at least one electromotive drive unit.
  • the assignment according to the invention of an electromotive drive unit likewise integrated in the handle section to the clutch element enables reliable actuation of the electromechanical clutch device by appropriate activation of the integrated electromotive drive unit.
  • the electromotive drive unit for motor drive of the coupling element is formed radially to the axis of rotation of the actuating polygon.
  • the electronically locked door handle can thus be switched quickly and reliably from the uncoupled state to the uncoupled state and vice versa.
  • the electromotive drive unit is drivingly connected to the coupling element via a drive element, preferably a drive element designed in the manner of a spindle.
  • the drive element which is preferably designed as a threaded spindle, can be integrated in the pusher section in a space-saving manner and enables the coupling element to be delivered quickly and reliably to the driver element and vice versa.
  • the coupling element located in the coupled position is also secured in position due to the non-rotatable connection established via the spindle-like drive element between the electromotive drive unit and the driver element, so that a reliable non-rotatable operative connection can be produced.
  • the coupling element is guided in the pusher section of the handle along a longitudinal axis of the pusher, for example by means of a sleeve-like guide element in the pusher section.
  • the Guidance preferably takes place on at least two opposite ones
  • the coupling element can advantageously be brought into lateral engagement with the driver element by displacing the coupling element radially to the axis of rotation and in the direction of the driver element. Likewise, an existing lateral engagement of the coupling element with the driver element can be released again by shifting the coupling element radially to the axis of rotation and away from the driver element. It is particularly advantageous for the mechanical clutch according to the invention not to require a great deal of force, so that an electromechanical drive unit with low power and therefore also reduced energy consumption can be used.
  • the driver element has a free, cylindrical end section accommodated in the neck section of the handle.
  • the cylindrical end section particularly advantageously forms a bearing axis for the handle in such a way that the neck section of the handle can be mounted on the cylindrical end section via a sleeve-shaped bearing element so that it can rotate about the axis of rotation.
  • An axially stable actuation of the handle is thus particularly advantageously possible even in the decoupled state, since the axial connection to the driver element continues to exist in the region of the neck section of the handle.
  • the free end of the driver element and the free end of the coupling element facing the driver element form a plug-in coupling with a male and female plug-in coupling part.
  • the male plug-in coupling part is preferably formed on the free, cylindrical end section of the driver element and the female plug-in coupling part is formed on the free end of the coupling element or vice versa.
  • a corresponding plug-in coupling can be produced in a space-saving and reliable manner using an electromechanical coupling device.
  • the cylindrical end section of the driver element has a nose-like projection which forms the male plug-in coupling part.
  • the nose-like projection preferably extends from the axis of rotation or longitudinal axis of the driver element along the longitudinal axis of the handle in the direction of the coupling element.
  • the female plug-in coupling part is correspondingly formed by a front coupling recess at the free end of the coupling element, which extends along the longitudinal axis of the handle and is open in the direction of the driver element.
  • the coupling recess on the end face is particularly advantageously designed to receive the nose-like projection of the cylindrical end section in a form-fitting manner.
  • the tongue-and-groove design of the plug-in coupling enables the torque generated by operating the handle to be optimally transmitted to the driver element.
  • the coupling element can have a cuboid coupling body with the front-side coupling recess, in such a way that the front-side free end of the coupling element is designed like a fork.
  • a cuboid coupling body enables a particularly reliable displacement of it within the pusher section.
  • a cylindrical coupling body or other suitable shapes, in particular several coupling bodies, can also be used.
  • At least one electronic control unit and one power supply are accommodated in the pusher section of the handle.
  • the complete control including the required energy supply, is then advantageously located in the door handle, i.e. it is wireless and ready for use without any further control components. Also, due to the integration into the door handle, no further assembly steps are required on the door.
  • an externally accessible fingerprint sensor can advantageously be arranged in the handle section, preferably on its underside or on its inner side facing the door leaf.
  • the pusher section particularly preferably has a recess adapted to the shape of a finger for receiving the fingerprint sensor.
  • the access authorization of the person is checked at the same time as usual gripping the door handle. A cumbersome further identification movement is thus eliminated.
