Definitions

  • the invention relates to a door handle, in particular a door handle, with a door-side output shaft and a handle facing away from the door leaf, the output shaft and the handle having a common axis of rotation and being connected to one another 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.
  • the shifting clutch is closed, however, the handle and the output shaft are connected to one another in a torque-proof manner.
  • case locks are generally used in doors, which are also referred to as mortise locks. Case locks are pushed into a recess in the narrow side of the door that is released when the door is opened and are fastened there.
  • box locks have a latch and usually a bolt. At least the latch can usually be pulled back via a door handle, usually in the form of a door handle, in order to open the door.
  • the bolt is also coupled to the handle, so that this is also pulled back when the handle is actuated.
  • the case lock In order to initiate the rotary movement of the door handle in the case lock, the case lock has a so-called nut into which a square shaft 17, which generally extends orthogonally to the door leaf, is inserted so that it protrudes over the door leaf on at least one side. The door handle is then placed on this free end in a rotationally locked manner.
  • the door is usually locked or released by so-called cylinder locks, which are inserted into the case locks.
  • the cylinder locks have a locking cam arranged on a shaft, which interacts with the box lock.
  • the locking cylinders allow the locking cam to be rotated if the user has the appropriate authorization; either a key or a knob is used to actuate the locking cam.
  • Electromechanical locking systems are based on electronic identification of a key.
  • the key can be an active or passive transponder.
  • a lock controller exchanges data with the key, checking the authorization of the key and releasing the lock if necessary.
  • the cam of electromagnetic locking cylinders In order to release the lock, the cam of electromagnetic locking cylinders must be connected to a handle, e.g. In the non-released state, at least the handle arranged on the outside of the door is not connected (uncoupled) in a rotationally fixed manner to the lock bit.
  • a clutch that can be switched by the lock controller is required, which on the one hand has to be so small that it can be integrated into a lock cylinder and on the other hand has to absorb comparatively high torques, so that stiff, e.g jammed locks can be opened.
  • Energy is usually supplied by batteries, which is why the energy requirement of the clutch for a closing and opening process must be as low as possible.
  • an electromechanical lock cylinder is described with an outer knob which can be non-rotatably coupled to a lock bit via an electric motor-actuated clutch.
  • a shaft is guided from the outer knob into an inner knob, where it carries a holder for a linear drive.
  • a coupling element can be pushed into a recess of a hollow shaft that is also led out of the lock cylinder.
  • the protruding end of the hollow shaft is expanded like a 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 the non-rotatable connection of two knobs with a lock bit.
  • the outer knob sits on a pin mounted in the lock cylinder, which is non-rotatably connected to a hollow shaft.
  • a clutch gear sits non-rotatably on the hollow shaft.
  • the clutch gear wheel is located in the half of the lock cylinder on the inside of the door and is overlapped by clutch claws that can be moved axially.
  • the clutch claws each have a driver projection pointing radially inward, which can be inserted between the teeth of the clutch gear wheel.
  • the claws can be coupled to the hollow shaft in a torque-proof manner.
  • the lock can be actuated by turning the outer knob.
  • the claws are seated on an axially slidable ring and extend from the ring towards the outside of the door.
  • the ring is also constantly non-rotatably connected to a flange carrying the inner knob. By moving the ring accordingly, the claws can be disengaged from the counter-claws, which decouples the inner knob from the cam.
  • US 6,460,903 B1 discloses a door lock with an inside knob and an outside knob acting on a door latch.
  • the inner knob is permanently connected to the door latch via a drive shaft so that it can be pulled back by turning the inner knob.
  • the outer knob has a ring which is non-rotatably connected to the corresponding handle and has face teeth, into which a coupling ring can be pushed by means of a slide.
  • the coupling ring has two radially attached driver wings, which each have two teeth complementary to the spur gearing.
  • the driver wings are mounted in two slots of a connecting element in an axially displaceable manner, 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 is seated in a rotationally fixed manner.
  • WO 2011/119097 A1 discloses a window handle with a lock that can be adjusted by an electric motor. Balls can be inserted in the radial direction into corresponding receptacles of a rosette screwed to the window by means of an axial slide, as a result of which the window handle is locked against rotation.
  • couplings are also known which are arranged under a cover arranged directly on the door leaf and are used to connect a door handle to the nut of a case lock ( EP 1662 076 B1 , EP 1 881 135 A1 , EP 1522659B , 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 door latch via a clutch.
  • a variant has an axially displaceable coupling element. In this variant, the knob on the inside acts on the latch.
  • the external knob acts on a shaft that can be coupled to an output shaft of the internal knob.
  • US 2010/0122561 A1 discloses another door lock for the American market with an internal handle and an external handle.
  • the inside handle is firmly connected to an inside drive sleeve to take a drive unit.
  • the external handle is first coupled to a drive socket.
  • the drive sleeve slides over an outer drive tube.
  • a clutch member is axially displaceable 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. The clutch is closed only when the clutch element engages in the two recesses at the same time.
  • KR 2011/0096955A branches a door handle set with an inside handle and an outside handle.
  • the door handle set has an axially displaceable slide with a circular-cylindrical lateral surface.
  • the slider seems to have a projection inside for coupling two shafts.
  • the object of the invention is to simplify the release of the lock by means of a lock cylinder, which is often perceived as cumbersome.
  • a door handle also known as a doorknob, is a lever-like device used to open and close a door's latch.
  • the door handle acts via a shaft, usually a square shaft, on what is known as the follower of a mortise lock (cf. e.g. DIN 18 251).
  • a door handle usually has two legs: a first leg, the longitudinal axis of which mostly, i.e. preferably, coincides with the rotation axis of the follower and a second leg attached to it at an angle, 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 usually significantly shorter than the second leg.
  • the door handle has an output shaft on the door side and a handle facing away from the door.
  • the output shaft can be connected to the nut of a box lock using a square shaft, for example.
  • the handle is used to pivot the door handle around an axis of rotation.
  • the handle and the output shaft have a common axis of rotation and are connected to one another via a preferably electromechanical clutch.
  • a clutch is understood to be a clutch that can be opened and closed.
  • the handle When open, the handle can be rotated freely in relation to the output shaft, i.e. the door cannot be opened.
  • the clutch When the clutch is closed (hereinafter referred to as the clutch), the handle and the output shaft are connected to one another in a torque-proof manner, which means that the door can be opened.
  • the adjustment of the shifting clutch between the two states “closed” and “open” preferably takes place electromechanically, so that a lock control can switch the shifting clutch between the two states.
  • the output shaft preferably has a recess on the side facing the handle, in which a coupling element is mounted, preferably in an axially displaceable manner.
  • the handle has a receptacle for the coupling element, preferably directly opposite the recess.
  • the recess, the coupling element and the receptacle are complementary to each other and at least in one section each are not rotationally symmetrical to the axis of rotation, so that a rotary movement is transmitted from the handle to the output via the coupling element if the coupling element, more precisely the at least one non-rotationally symmetrical section, engages the complementary portions of both the recess and the socket.
  • the clutch When the coupling element engages in the recess and the receptacle in a rotationally locked manner, the clutch is closed and the coupling element is correspondingly in its closed position. If the coupling element only engages in the receptacle or only in the recess in a rotationally locked manner, then the clutch is open and the Kupplungslement in the open position. Ultimately, the recording is a recess of the handle. The term is only used for the linguistic distinction between the two recesses. Alternatively, one could also speak of a first recess (the recess) and a second recess (the receptacle).
  • a linear drive is arranged in the handle, which acts on the coupling element in order to displace the coupling element in the axial direction far enough out of the recess to close the clutch that it engages both in the recess and in the receptacle, and it to open the clutch shifted from the recording back into the recess.
  • Such a clutch is very reliable, compact and can also transmit large torques with only a small amount of material used.
  • this clutch can be arranged in a very narrow shaft, i.e. in a narrow leg of a door handle on the door side. The door handle can therefore be correspondingly slim and does not necessarily differ optically from the usual rigid door handles without a clutch.
  • the recess preferably completely accommodates the coupling element in its open position. In the closed position of the coupling element, it is preferably completely in a cavity formed by the recess and the receptacle.
  • the clutch can be made particularly compact.
  • the end faces of the output shaft and the handle lie against one another (forming a rotary gap or a plain bearing), which means that tilting moments can be introduced from the handle into the output shaft, which increases the stability of the door handle.
  • the output shaft is preferably rotatably mounted in a door-side recess of the handle. This can ensure that a displacement of the coupling element is not disturbed by forces acting radially to the axis of rotation on the handle.
  • the handle is preferably rotatably mounted relative to the door leaf.
  • a rosette spanning the end of the handle on the door side can be designed as a bearing for the handle.
  • Such a rosette can also be screwed to the door leaf from the inside of the door and thus make it more difficult to attack the coupling of the door handle mounted on the outside.
  • the rosette preferably has no function, in this respect the door handle is then self-sufficient.
  • the coupling element is preferably pretensioned in the direction of the handle. Then it is sufficient to close the clutch to release the path of the clutch element in the direction of the recording. As soon as the output shaft and the handle are then aligned with one another, the coupling element is displaced so that it engages in the receptacle and in the recess. The clutch is now closed. To open the clutch, the clutch element is pushed out of the receptacle, which increases the preload again.
  • a preloading spring for example a coil spring, can be arranged between the bottom of the recess and the coupling element for preloading.
  • a rosette for attachment to a door leaf preferably overlaps the handle and is connected to the handle via a return spring in such a way that the handle is pretensioned in the direction of its closed position against a stop.
  • the handle is in a well-defined position, e.g. the usual horizontal position, even when the clutch is open.
  • the handle preferably has a hollow shaft on the door side, in which the output shaft and at least part of the linear drive are arranged.
  • the handle protects the output shaft from unauthorized access and a particularly compact design is made possible.
  • the output shaft is particularly preferably rotatably mounted in the hollow shaft; when the clutch is engaged, the ability to rotate is of course blocked or at least restricted.
  • the handle can have a handpiece which is connected to the hollow shaft in a torque-proof manner and has two legs which are arranged at an angle to one another.
  • the door handle then has the form of a conventional door handle.
  • the handpiece has at least two half-shells, between which at least one fastening section of the hollow shaft is arranged.
  • the half-shells can have an external thread on the door side, on which a union nut is seated, which fixes the half-shells on the hollow shaft.
  • the union nut should preferably be protected against unauthorized opening, e.g. be reached over by a rosette or be locked by a stop that can only be reached when the door handle is dismantled.
  • At least one battery for supplying energy to the door handle can be arranged in the leg of the handpiece facing away from the door, i.e. in the leg of the handpiece which is at least approximately parallel to the door leaf.
  • the ends of the two half-shells facing away from the door can end in a hollow profile, which holds the ends together and, for example, offers space for at least one battery or also for at least parts of a circuit, for example a lock control.
  • the linear drive preferably has at least one control slide which is mounted in the handle in an axially displaceable and rotatable manner and which acts on the coupling element in such a way that a displacement of the control slide causes a displacement of the coupling element.
  • the control slide has at least one 'open position' in which the clutch is open and a 'closed position' in which the clutch is closed.
  • the control slide preferably has at least one e.g. Alternatively, the control slide can also only have a thread-like contact surface for the pin or the thread section, in which case the control slide and/or the pin or thread section are spring-loaded against one another. As a result, a rotary movement of the control slide can be converted into a linear movement, i.e. a rotation of the control slide also causes a linear movement, preferably axially to the axis of rotation.
  • the control slide can be driven by a motor controlled by a lock control, for example.
  • the motor can preferably be arranged in the handle and at least indirectly drive a drive wheel for the control slide.
  • the drive wheel can preferably be arranged coaxially to the axis of rotation of the control slide.
  • the drive wheel is connected to the spool valve in order to take it with it when it rotates.
  • the control slide and the drive wheel are connected to each other via a spring element, e.g. a coil spring.
  • the spring element compensates for the changes in the distance between the actuating element and the drive wheel during an axial displacement of the actuating element, and it also serves as an energy store when the actuating element is blocked.
  • the control slide is to be moved in the direction of the output shaft, it may be that the coupling element is loaded, e.g. by an actuation of the pusher, so that it jams. Accordingly, a movement of the control slide in the direction of the coupling element is not possible.
  • the motor can be controlled by the lock control, thereby driving the drive wheel and tensioning the spring element in the corresponding direction of rotation. As soon as the coupling element is relieved, i.e. is no longer jammed, the blockage of the control slide is also lifted. The energy stored in the spring element is converted into a displacement of the control slide and the clutch element is thus also displaced accordingly.
  • the drive wheel is preferably partially toothed, ie it has a toothed area and, in its extension, a non-toothed area, with the angular range spanned by the toothed area corresponding to the angle of rotation of the drive wheel that is necessary to move the control slide between its 'open position' in which the clutch is open and its 'closed position' in which the clutch is closed to adjust.
  • Electrical components e.g. a lock control or a part thereof, can be arranged in the handle, in particular in a cavity between at least two half-shells of the handle.
  • the lock control is set up to exchange data with an electronic key, e.g. an RFID transponder, via a data path, e.g. a radio data path. Based on the data, the lock control checks the locking authorization of the key and controls the linear drive if the locking authorization does not correspond to the status of the clutch, i.e. if the locking authorization is given, the clutch is closed and otherwise opened if necessary.
  • FIG. 1 shows a door handle 1.
  • the door handle has a handle 10 that can be pivoted about an axis of rotation 2, with a door-side first leg 11, the longitudinal axis 2 of which is oriented approximately orthogonally to a door leaf (not shown) in the assembled state, and with a second leg 12 that is angled thereto
  • the area where the first and second legs meet at an angle consists of two half-shells 13, 14 held together by a nut 15 on the door side and a sleeve 16 on the other side.
  • the door handle 1 can have a receptacle for a square shaft 17 in order to couple the door handle to the nut of a box lock in a torque-proof manner.
  • a rosette 18 can be provided for fastening and mounting the door handle 1 on a door leaf and can protect the clutch, which is described in more detail below, against manipulation.
  • Covered by the handle 10 is an output shaft 30 (cf. Figures 2a to 3b ), which acts on the square shaft 17 shown, i.e. is connected to the square shaft 17 in a manner that transmits rotational movement, i.e. rotational movements about the longitudinal axis 2 are transmitted, whereas tilting moments acting orthogonally to the longitudinal axis 2 are preferably at least largely derived from the mounting of the handle 10 intercepted by 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 preferably supported on the rosette 18 via a return spring 19, so that the door handle 1 does not hang down when the clutch is open.
  • the rosette 18 in turn can preferably be screwed to the door leaf from the inside of the door or fastened thereto in some other way.
  • the door handle 1 has an output shaft 30 on the door side, 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 connected to one another in a torque-proof manner via the clutch.
  • the output shaft 30 can be connected to the square shaft 17 in a torque-proof manner.
  • the hollow shaft 50 is connected to the handle 10 in a torque-proof manner.
  • the hollow shaft 50 has a fastening section 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 is seated so that it can be displaced axially but not freely rotated.
  • the coupling element 40 can be (circular)cylindrical, for example, and has a cam 401 (two cams 401 are shown) on at least one side, which (each) engages in a complementary groove of the recess 31.
  • the coupling element 40 can have at least one flat area which interacts with a complementary flat area 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 to the axis of rotation.
  • the hollow shaft 50 has a receptacle 51 that is also complementary to the shape of the coupling element 40.
  • the coupling element 40 is pushed into the receptacle 51 in the axial direction until the coupling element 30 engages both in the recess 31 and in the receptacle 51 , the hollow shaft 50 and thus the handle 10 are rotatably connected to the output shaft 30, ie the clutch is closed.
  • the output shaft 30 is therefore carried along and the rotary motion is transmitted to the square shaft 17 .
  • the clutch element 40 is preferably adjusted by means of a control slide 41.
  • the control slide 41 shown by way of example is mounted on a rod 54 in the hollow shaft 50 so that it can rotate and be axially displaceable.
  • the control slide 41 has a thread-shaped slot 42 (more generally: a thread 42) in which a pin 53 engages radially as a complementary threaded section, the threaded section 53 being at least substantially rigidly connected to the handle 10 via the rod 54.
  • the rod 54 is held by a gear block 61, but other attachments are also possible. It is only important that the rod 54 and the control slide 41 can be rotated about the longitudinal axis 2 relative to one another.
  • control slide 41 When the control slide 41 rotates about its longitudinal axis 2, it is either advanced in the direction of the output shaft 30 or retracted in the opposite direction, depending on the direction of rotation, due to the interaction of the threaded section 53 and the thread turn 42.
  • the control slide 41 When the control slide 41 is advanced, it presses the coupling element 40 against the force of a spring 32, which is supported on the bottom of the recess 31, so far into the recess 30 that the coupling element 40 does not engage in the receptacle 51; the clutch is now open.
  • the control slide has reached one of its two end positions, namely its 'open end position'.
  • control slide 41 If the control slide 41 is turned back and thereby pulled back, then the coupling element 40 follows the control slide 41 into the receptacle 51 of the hollow shaft 50 because of the spring 32, the spring 32 being at least somewhat relaxed; the clutch is closed.
  • the control slide 41 has now reached the other end position, the so-called closed end position.
  • a motor 45 controlled by a lock control drives a drive wheel 44 which is preferably arranged coaxially to the control slide 41 via a preferably self-locking gear.
  • the drive wheel 44 takes along a first end of a spring element 43 (at least indirectly).
  • the other, second end of the spring element 43 is attached to the control slide 41 (at least indirectly), so that when the drive wheel 44 rotates, the control slide 41 is rotated, provided the coupling element is not blocked.
  • the actuating element 41 and thus also the coupling element 40 are displaced axially due to the threaded section 53 engaging axially in the thread.
  • the spring element 43 is tensioned by the rotation of the two ends against one another. As soon as the blockage is removed, the control slide 41 follows the rotation of the drive wheel 44, the spring element being relaxed again.
  • the handle 10 When the drive wheel 44 is driven to to open the clutch, ie to advance the control slide 41, it may be that the handle 10 is actuated at the same time.
  • the coupling element 40 is clamped between the output shaft 30 and the hollow shaft 50 and thereby blocks an axial displacement of the control slide 41. Therefore, only the spring element 43 is tensioned by the rotation of the drive wheel 44, i.e. kinetic energy is stored as potential energy in the spring element 43 . If the handle 10 is now released, the clamping of the coupling element 40 is released, ie the control slide 41 prestressed by the spring element 43 can move the coupling element 40 out of the receptacle 51 and thus into the 'open position'.
  • the clutch is open when the door handle is actuated. Then the receptacle 51 of the hollow shaft 50, i.e. the handle, is rotated against the recess 31 of the output shaft 30 and the coupling element 40 cannot engage in the receptacle 51 even if the control slide 41 is pulled back. The coupling element 40 can therefore not follow the control slide 41 despite the prestressing by the prestressing spring 32 . However, 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 part-toothed gear, ie the drive wheel has at least a first toothed area and a second non-toothed area, the non-toothed area being arranged in the imaginary extension of the toothed area.
  • an output element driven by the motor 45 for example a worm (shown in Fig Figure 2a ), a rack or other gear into the toothed area of the drive wheel 44.
  • the toothed area is arranged on the drive wheel in such a way that the toothing no longer engages in the driven element as soon as the first end of the spring element 43 has reached one of 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'. In order to adjust the control slide 41 between its corresponding end positions, it is therefore sufficient to control the motor with the corresponding direction of rotation for a sufficiently measured time. As soon as the entrained end of the spring element 43 has assumed its desired end position, the output element and the drive wheel 44 are disengaged. The motor 45 can therefore be operated in a time-controlled manner and sensors that detect an end position of the first end of the spring element are not necessary. It is sufficient to select a sufficiently large time constant for controlling the motor.
  • the control slide is now spring-loaded in the direction of its corresponding end position and the 'last tooth' of the toothed area is moved by the spring element 43 accordingly pressed against the complementary teeth of the output element. If now the control slide 41 is to be moved into its other end position, then it is sufficient to activate the motor 45 again for a sufficiently measured period of time, but now with the reverse direction of rotation. The toothings engage in one another again until the entrained end of the spring element 43 reaches its second end position.
  • control slide is now spring-loaded in the direction of its corresponding (other) end position and the 'first tooth' of the toothed area lies against the complementary toothing of the output element due to the spring load. Therefore, if the direction of rotation of the motor 45 were reversed again, the drive wheel 44 would be taken along again by the driven element.
  • the door handle was described using 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.
  • the output shaft can be kept relatively short, which makes it difficult to attack.
  • the clutch can be rotated through 180°, then the clutch element 40 would be in the open position in the handle.
  • the linear drive can be arranged in the handle or in or on the output shaft.
  • An essential advantage of the invention is that the rosette does not house any elements that are necessary for shifting the clutch.
