Definitions

  • the invention relates to a door handle, in particular a door handle having a door-side output shaft and a handle facing away from the door leaf, wherein the output shaft and the handle have a common axis of rotation and are connected to each other via a preferably electromechanical clutch, so that when the clutch is open, the handle is actuated, ie can be rotated without taking the output shaft. When the clutch is closed, however, the handle and the output shaft are rotatably connected.
  • box locks are usually used in doors, which are also referred to as mortise locks. Caste locks are inserted into a recess in the open when opening narrow side of the door and are fixed there. These box locks have a trap and usually a bolt. At least the case can usually be withdrawn via a door handle, usually in the form of a door handle to open the door. In so-called anti-panic locks and the bolt is coupled to the pusher, so that this is withdrawn upon actuation of the pusher.
  • the box lock In order to initiate the rotational movement of the door handle in the box lock, the box lock has a so-called nut in which usually a square shaft 17 extending orthogonal to the door leaf is inserted so that it protrudes on at least one side over the door leaf. On this free end of the door handle is then placed rotationally.
  • Locking or releasing the door is usually done by so-called cylinder locks, which are used in the box locks.
  • the cylinder locks have a locking cam arranged on a shaft, which cooperates with the box lock.
  • the lock cylinder allow for a given authorization of the user rotation of the lock cam, either serves a key or a knob for actuating the lock cam.
  • Electromechanical locking systems are based on an electronic identification of a key.
  • the key may be, for example, an active or passive transponder.
  • a lock control exchanges data with the key, checking the authorization of the key and releasing the lock if necessary.
  • the cam In order to release the lock, in the case of electromagnetic lock cylinders, the cam must be engaged with a handle, e.g. rotatably connected with a knob, so be coupled. In the non-released state at least arranged on the outside of the door handle is not rotatably connected to the cam (decoupled).
  • an electromechanical lock cylinder described with an outside knob, which can be rotatably coupled via an electric motor-operated clutch with a lock bit.

  • a coupling element can be inserted into a recess of a likewise guided out of the lock cylinder hollow shaft.
  • the led out end of the Hollow shaft is extended flange and carries the inner knob.
  • the other end of the hollow shaft carries the cam.
  • DE 10 2004 056 989 A1 also describes a lock cylinder with a coupling for non-rotatable connection of two knobs with a cam.
  • the outside knob sits on a pin mounted in the lock cylinder, which is connected to a hollow shaft in a torque-proof manner.
  • On the hollow shaft is rotatably a clutch gear.
  • the clutch gear is located in the door inside half of the lock cylinder and is overlapped by axially movable coupling jaws.
  • the coupling claws each have at their distal end a radially inwardly facing driver projection, which can be inserted between the teeth of the clutch gear. As a result, the claws can be coupled with the hollow shaft in a rotationally fixed manner.
  • the lock can be actuated by turning the outer knob.
  • the claws sizten on an axially displaceable ring and extend from the ring towards the outside of the door.
  • the ring is also constantly rotatably connected to a inner knob bearing flange. By appropriate displacement of the ring, the claws can be disengaged from the counter-jaws, whereby the inner knob is decoupled from the cam.
  • US Pat. No. 6,460,903 B1 discloses a door lock with an inner knob and an outer knob, which act on a door latch.
  • the inner knob is constantly connected via an output shaft with the door latch, so that it can be constantly retracted by a rotation of the inner knob.
  • the outer knob has a rotatably connected to the corresponding handle ring with a spur gear teeth, in which a coupling ring can be inserted by means of a slider.
  • the coupling ring has two radially arranged driving wing, each having two complementary to the spur teeth teeth.
  • the driver wings are axially displaceable in two slots of a connecting element stored, so that a rotation of the coupling ring is transmitted to the connecting element.
  • the connecting element has a receptacle in which the output shaft rotatably seated.
  • a window handle with an electromotive adjustable locking disclosed in the WO 2011/119097 A1 is a window handle with an electromotive adjustable locking disclosed.
  • an axial slide balls can be inserted in the radial direction into corresponding receptacles of a bolted to the window rosette, whereby the window handle is locked against rotation.
  • couplings are also known, which are arranged under a cover arranged directly on the door leaf and serve to connect a door latch to the nut of a box lock ( EP 1662 076 B1 . EP 1 881 135 A1 . EP 1522659 B . DE 10 2009 018 471 A ). For aesthetic reasons, however, these are only accepted to a limited extent.
  • WO96 / 41486A1 describes an electronic door lock for the US market. Accordingly, it has two knobs that act on a clutch on a door latch. A variant has an axially displaceable coupling element. In this variant, the inside knob acts on the trap. The outer knob acts on a shaft that can be coupled to an output shaft of the inner knob.
  • US 2010/0122561 A1 discloses another door lock for the American market with an internal handle and an external handle.
  • the internal handle is firmly connected to an inside drive sleeve to take a drive unit.
  • a clutch Between the outer handle and the drive unit is a clutch.
  • the external handle is first coupled to a drive socket.
  • the drive bush slides over an outer drive tube.
  • a coupling member may be axially displaced to couple the outer drive tube to the outer drive sleeve.
  • the outer drive tube and the outer drive bush each have an axial recess. Only when the coupling element simultaneously engages in the two recesses, the clutch is closed.
  • KR 2011 / 0096955A branches a doorknob set with an inner pawl and an outer pawl.
  • the door handle set has an axially movable slide with a circular cylindrical surface.
  • the slider seems to have in its interior a projection for coupling two waves.
  • the invention has for its object to simplify the often perceived as cumbersome release of the lock by means of a lock cylinder.
  • a door handle also referred to as a door handle, is a lever-type device for opening and closing the door of a door.
  • the door handle acts via a shaft, usually a square shaft on the so-called pusher nut, in short 'nut', a mortise lock (see, for example, DIN 18 251).
  • a door handle usually has two legs: a first leg whose longitudinal axis is usually, i. preferably coincides with the axis of rotation of the nut and an angled attached thereto second leg which acts as a lever.
  • the second leg is pivoted about the longitudinal axis of the first leg and rotates it accordingly.
  • the first leg is significantly shorter than the second leg.
  • the door handle has a door-side output shaft and a handle facing away from the door.
  • the output shaft can be connected as usual via e.g. a square shaft can be connected to the nut of a box lock.
  • the handle serves to pivot the door handle about an axis of rotation.
  • the handle and the output shaft have a common axis of rotation and are connected to each other via a preferably electromechanical clutch.
  • a clutch Under a clutch is a clutch understood that can be opened and closed. In the open state, the handle is freely rotatable relative to the output shaft, i. the door can not be opened. In the closed state of the clutch (hereafter short clutch), the handle and the output shaft are rotatably connected to each other, therefore, the door can be opened.
  • the adjustment of the clutch between the two states 'closed' and 'open' is preferably carried out electromechanically, so that a lock control can switch the clutch between the two states.
  • the recess preferably directly opposite the handle has a receptacle for the coupling element.
  • the recess, the coupling element and the receptacle are complementary to each other and at least in each case a portion not rotationally symmetrical to the axis of rotation, so that via the coupling element, a rotational movement is transmitted from the handle to the output, when the coupling element, more precisely the at least one non-rotationally symmetric portion engages in the complementary portions of both the recess and the receptacle.
  • the clutch When the coupling element rotatably engages in the recess and the receptacle, then the clutch is closed and the Kupplungslement according to its closed position. If the Kupplungselment engages only in the receptacle or only in the recess rotationally, then the clutch is open and the Kupplungslement in the open position. Finally, the recording is a recess of the handle. Only the linguistic distinction between the two recesses, the term is used. Alternatively, one could also speak of a first recess (the recess) and a second recess (the receptacle).
  • a linear drive is arranged, which acts on the coupling element to move the coupling element for closing the clutch in the axial direction as far out of the recess that it engages in both the recess and in the receptacle, and to open the clutch from the receptacle back into the recess moves.
  • a clutch is very reliable, compact and can also transmit high torques with little use of material.
  • this clutch can be in a very narrow shaft, i. Arrange in a narrow door-side leg of a door handle. The door handle can therefore be correspondingly slim and visually does not necessarily differ from the usual rigid door handles without clutch.
  • the recess takes the coupling element in its open position completely. In the closed position of the coupling element, it is preferably completely formed in one of the recess and the receptacle Cavity.
  • the clutch can be made particularly compact.
  • the end faces of the output shaft and the handle abut each other (forming a rotating nip or a sliding bearing), whereby tilting moments can be introduced from the handle to the output shaft, which increases the stability of the door handle.
  • the output shaft is rotatably mounted in a door-side recess of the handle.
  • the handle is preferably rotatably mounted relative to the door leaf.
  • a the door-side end of the handle cross-rosette be designed as a bearing for the handle.
  • Such a rosette can also be screwed from the inside of the door with the door leaf and thereby complicate an attack on the coupling of the door handle mounted on the outside.
  • the rosette preferably has no function, in this regard, the door handle is then self-sufficient.
  • the coupling element is biased in the direction of the handle. Then it is sufficient to close the clutch release the path of the coupling element in the direction of recording. As soon as then the output shaft and the handle are aligned according to each other, the coupling element is moved so that it engages in the receptacle and in the recess. The clutch is now closed. To open the clutch, the coupling element is moved out of the receptacle, whereby the bias voltage is increased again.
  • a biasing spring such as a coil spring.
  • a rosette for attachment to a door leaf engages over the handle and is connected via a return spring in such a manner with the handle, that the handle is biased in the direction of its closed position against a stop.
  • the handle is in a well-defined, e.g. the usual horizontal position.
  • the handle has a door-side hollow shaft, in which the output shaft and at least a part of the linear drive are arranged.
  • the handle protects the output shaft against unauthorized access and it allows a particularly compact design.
  • the output shaft is rotatably mounted in the hollow shaft, when closing the clutch rotation is of course blocked or at least limited.
  • the handle may have a rotatably connected to the hollow shaft handpiece with two angularly arranged legs.
  • the door handle then has the shape of a conventional door handle.
  • the handpiece has at least two half-shells, between which at least one fastening portion of the hollow shaft is arranged.
  • the half shells on the door side have an external thread on which a union nut sits, which fixes the half-shells on the hollow shaft.
  • the union nut should preferably be protected against unauthorized opening, e.g. be overlapped by a rosette or locked by a reachable only with disassembled door handle stop.
  • At least approximately parallel leg of the handpiece can be arranged at least one battery for powering the door handle.
  • the ends of the two half-shells facing away from the door can open into a hollow profile which holds their ends together and, for example, space for at least one half Battery or even for at least parts of a circuit, for example, a lock control offers.
  • the linear drive preferably has at least one axially displaceable and rotatably mounted in the handle spool, which acts on the coupling element such that a displacement of the spool causes a displacement of the coupling element.
  • the spool has at least one 'open position' in which the clutch is open and a 'closed position' in which the clutch is closed.
  • the spool preferably has at least one e.g. slit-shaped thread, in which engages a pin or a complementary threaded portion which is rigidly connected to the handle.
  • the spool may also have only a thread-like contact surface for the pin or the thread portion, in which case the spool and / or the pin or thread portion are spring-loaded against each other.
  • the drive of the spool can be done via an example controlled by a lock control motor.
  • the motor may preferably be arranged in the handle and at least indirectly drive a drive wheel for the spool.
  • the drive wheel may for this purpose preferably be arranged coaxially to the axis of rotation of the spool.
  • the drive wheel is connected to the spool to take it with a rotary motion.
  • the spool and the drive wheel via a spring element, such as a coil spring are connected together.
  • the spring element compensates for a change in the distance between the actuator and the drive wheel with an axial displacement of the actuating element and it also serves as energy storage, when the actuator is blocked.
  • the motor can be controlled by the lock control, while it drives the drive wheel and biases the spring element in the corresponding direction of rotation. Once the coupling element is relieved, that is no longer jammed, the blockage of the spool is repealed. The stored energy in the spring element is converted into a displacement of the spool and thereby also the coupling element is moved accordingly.
  • the drive wheel is serrated, i. it has a toothed portion and in its extension a non-toothed portion, wherein the angular range spanned by the toothed portion corresponds to the rotation angle of the drive wheel, which is necessary to the spool between its 'open position' in which the clutch is opened and its 'Closed position' in which the clutch is closed to adjust.
  • a lock control In the handle, in particular in a cavity between at least two half shells of the handle electrical components, such as a lock control or a part thereof may be arranged.
  • the lock control is set up to exchange data with an electronic key, eg an RFID transponder, over a data link, for example a radio data link. Based on the data, the lock control checks the locking authorization of the key and controls the linear drive, if the lock authorization does not correspond to the state of the clutch, ie at a given locking authorization, the clutch is closed and otherwise open, if necessary.

  • a rosette 18 may be provided for attachment and storage of the door handle 1 on a door leaf and protect the clutch described in more detail below from manipulation.
  • Covered by the handle 10 is an output shaft 30 (see. Fig. 2a to 3b ), which acts on the illustrated square shaft 17, that is connected rotationally transmitting with the square shaft 17, ie rotational movements about the longitudinal axis 2 are transmitted, whereas tilting moments acting orthogonally to the longitudinal axis 2 are preferably at least largely intercepted by the mounting of the handle 10 through the rosette 18 and introduced into the door leaf.
  • a clutch to the handle 10 by a lock control rotatably connected to the output shaft 17 (clutch closed) or to decouple the two (clutch open).
  • the handle 10 is supported by a return spring 19 on the rosette 18, then hangs lever handle 1 with open clutch not down.
  • the rosette 18, in turn, may preferably be bolted or otherwise secured to the door panel from inside the door.
  • the operation of the door handle is based on the two sections AA and BB ie the Figures 2a to 3b explains:
  • the door handle 1 has the door side, an output shaft 30 which is rotatably mounted in a hollow shaft 50 of the handle 10.
  • the output shaft 30 and the hollow shaft 50 have a common axis of rotation 2 and can be rotatably connected to each other via the clutch.
  • the output shaft 30 may be rotatably connected to the square shaft 17 as shown.
  • the hollow shaft 50 is rotatably connected to the handle 10.
  • the hollow shaft 50 has a mounting portion 52, with which it is fixed between the two half-shells 13, 14.
  • the output shaft 30 has on its side facing the hollow shaft 50 a recess 31 in which a coupling element 40 axially slidably but not freely rotatably seated.
  • the coupling element 40 may, for example, be (circular) cylindrical and has on at least one side a cam 401 (shown are two cams 401) which engage (respectively) a complementary groove of the recess 31 (engage).
  • the coupling element 40 may have at least one flattening which cooperates with a complementary flattening of the hollow shaft 50 and the output shaft 30. It is only important that the coupling element 40 can form a torque-transmitting positive connection with the hollow shaft 50 and / or with the output shaft 30 depending on the position.
  • the cylindrical part of the coupling element 40 is arranged coaxially with the axis of rotation.
  • the recess 30 opposite the hollow shaft 50 has a likewise complementary to the shape of the coupling element 40 receptacle 51.
  • the adjustment of the coupling element 40 is preferably carried out by means of a control slide 41.
  • the control spool 41 shown by way of example is rotatably and axially displaceably mounted in the hollow shaft 50 on a rod 54.
  • the spool 41 has a thread-shaped slot 42 (formulated more generally: a thread 42) in which a pin 53 radially engages as a complementary threaded portion, wherein the threaded portion 53 is at least substantially rigidly connected to the handle 10 via the rod 54.
  • the rod 54 is held by a gear block 61, other fasteners are possible. It is only important that the rod 54 and the spool 41 relative to each other about the longitudinal axis 2 can be rotated.
  • a motor 45 (not shown) controlled by a lock control drives, via a preferably self-locking transmission, a drive wheel 44, which is preferably arranged coaxially with the control slide 41.
  • the drive wheel 44 thereby takes a first end of a spring element 43 (at least indirectly).
  • the other, second end of the spring element 43 is (at least indirectly) attached to the spool 41, so that upon rotation of the drive wheel 44 of the spool 41 is rotated, unless the coupling element is blocked.
  • the actuating element 41 and thus also the coupling element 40 are displaced axially due to the threaded portion engaging axially into the threaded portion 53.
  • the spring element 43 is tensioned by the rotation of the two ends against each other. Once the blockage is lifted, the spool 41 follows the rotation of the drive wheel 44, wherein the spring element is relaxed again.
  • the clutch is open when the door handle is pressed. Then, the receptacle 51 of the hollow shaft 50, i. the handle against the recess 31 of the output shaft 30 is rotated and the coupling element 40 can not even into the receptacle 51 engage, when the spool 41 is withdrawn. The coupling element 40 can therefore not follow the spool 41 despite the bias by the biasing spring 32. But as soon as the door handle is released, the grooves of the recess 31 and the receptacle 51 are aligned, so that the coupling element 40 engages in the receptacle 51 of the hollow shaft 50 and thereby closes the clutch.
  • the drive wheel 44 is a partially toothed gear, that is, the drive wheel has at least a first toothed portion and a second untoothed portion, wherein the untoothed portion is disposed in the imaginary extension of the toothed portion.
  • a driven by the motor 45 driven element such as a worm (shown in FIG Fig. 2a ), a rack or other gear in the toothed portion of the drive wheel 44 a.
  • the toothed area is arranged on the drive wheel so that the teeth are no longer in the driven element engages as soon as the first end of the spring element 43 has reached its two end positions.
  • the control slide In the first end position, the control slide is spring-loaded in the direction of its 'closed end position' and in the other end position in the direction of its 'open end position'.
  • the motor In order to adjust the spool 41 between its corresponding end positions, it is therefore sufficient for the motor to drive a sufficiently long time with the corresponding direction of rotation.
  • the output element and the drive wheel 44 become disengaged.
  • the motor 45 can therefore be operated time-controlled and sensors that detect an end position of the first end of the spring element are not necessary. It is sufficient to choose the time constant for driving the motor sufficiently large.
  • the spool 41 When the desired end position of the entrained first end of the spring element 43 is reached and the drive wheel 44 and the output element are not toothed together, the spool is now spring-loaded in the direction of its corresponding end position and the 'last tooth' of the toothed portion is corresponding to the spring element 43 pressed against the complementary teeth of the output element. Now, if the spool 41 is to be moved to its other end position, then it is sufficient to drive the motor 45 again for a sufficiently sized period, but now with the reverse direction of rotation. The teeth engage again in each other until the entrained end of the spring element 43 reaches its second end position.
  • the spool is spring-loaded in the direction of its corresponding (other) end position and 'first tooth' of the toothed region is due to the spring load on the complementary toothing of the output element. Therefore, the drive wheel 44 would be taken in a renewed reversal of the motor 45 again by the output element.
  • the door handle has been described with reference to an example in which the coupling element is seated in the output shaft when the clutch is open and the linear drive is integrated in the handle. This allows the output shaft be held relatively short, which makes it difficult to attack.
  • the clutch can be rotated by 180 °, then sitting the coupling element 40 in the open position in the handle. Regardless of the linear drive can be arranged in the handle or in or on the output shaft.
  • a significant advantage of the invention is that the rosette accommodates no necessary for the switching of the clutch elements.
