Definitions

  • the invention relates to a door lock for a door with a first actuating element, which is at least indirectly coupled to a generator and with a closing element to drive the generator via the first actuating element, while a closing element is actuated to open the door with the first actuating element.
  • a second actuating element may be coupled to the generator in order to drive the generator via the second actuating element, while a closing element for opening the door is actuated with the second actuating element
  • Electromechanical door locks can usually be unlocked by a mostly electronic key is queried and checked for access authorization. If the check reveals that an access authorization exists, in many cases an electronically controlled clutch is closed so as to couple an actuating element with a closing element. After the door has been opened via the actuating element, the coupling can be opened again so that a key has to be interrogated again to reopen the door.
  • Typical keys are character strings stored in RFID transponders which are preferably encrypted via a contactless data link.
  • Other systems provide electrical and / or mechanical contact between the key and the door lock. In other systems, a code must be entered via an HMI (Human Machine Interface). Typical HMIs are keyboards, fingerprint or iris scanners.
  • the electrical components of the door locks must be supplied with electrical energy.
  • batteries have been used in practice so far in the Lock and / or be inserted in the key.
  • the locks are connected via corresponding lines to a power grid.
  • the connection to a power grid is complex and error-prone. This is especially true if an electromechanical door lock to be retrofitted and the necessary lines must be relocated. Batteries have the disadvantage that they must be replaced regularly.
  • a variety of systems have been described in which when the door lock is actuated by the user, mechanical energy or power is converted into electrical energy or power by means of a generator.
  • DE 195 19 789 B4 describes an electromechanical door lock with a mechanical energy storage, which is charged in the operation of a door handle or when inserting a key until a predetermined energy is stored in the mechanical energy storage.
  • the mechanical energy storage is discharged within a predetermined time, where it drives a generator.
  • the electrical components for this period of time can be supplied with a defined power. Consequently, the electrical power available for the electrical components is decoupled from the manner of actuation of the door handle or key.
  • the DE 32 08 818 describes an electromechanical door lock with a lock cylinder in the operation of the castle as usual, first inserted a key and then rotated.
  • a lock cylinder In order to provide the energy for the electrical components of the door lock of the lock cylinder has a slide which is displaced parallel to the lock cylinder axis against the force of a spring upon insertion of a key, while meshing a gear which is coupled to a generator shaft.
  • turns the gear and the generator provides an electrical power that depends, inter alia, on the speed with which the key is inserted or withdrawn.
  • box locks are usually installed in doors between two rooms of a building or building entrance doors. These box locks usually have a latch and a latch.
  • the trap is usually operated via a door handle.
  • the door handle sits mostly on a square shaft, which was inserted through a driver of the box lock.
  • the latch can be actuated by a cam of a replaceable lock cylinder.
  • the latch can also be operated by means of the lock cylinder when the latch is retracted. Thereby, e.g. On the inside of the door a door handle can be attached to operate the trap. Then the unlocked lock can be opened from the inside without a key.
  • On the outside usually a rigid knob is arranged, which is not coupled with the box lock. Then the door can be opened from the outside only by means of the lock cylinder.
  • the bolt can be pulled back from the inside of the door by pressing the door handle, which makes sense in escape doors.
  • Such locks are referred to as anti-panic locks or panic locks.
  • no door handle on the outside is constantly connected to the box lock, because then it makes no sense to advance the bolt, because he would in any case retracted when pressing one of the two door handle.
  • the invention has for its object to provide a door lock that converts mechanical power into electrical power when operating a door handle.
  • the invention is based on several findings: Firstly, the angle range in which a door handle is usually pivoted is comparatively small (about 30 °) and the time span in which this takes place is quite short. Therefore occur on the components with which the generator coupled to the actuator are high (rotational) moments, which require a strong dimensioning of these components. In addition, the recoverable upon actuation of a door handle electrical energy is quite small, therefore, even with panic locks every actuation of a door handle, so whether inside or outside and whether driving before or after a successful authorization check a generator. However, the outer door handle must not take the inner, because this would open the door without authorization check.
  • the door lock has at least a first actuating element.
  • the actuating element is typically a door handle or a rotatable knob, which are summarized by the term "door handle” or “pusher” and usually sit on a square shaft.
  • the lock is actuated via the door handle. This operation is transmitted for example via a shaft, for example via the known square shaft. In this sense, a shaft for transmitting the pivoting movement of a door handle is also an actuating element.
  • the actuating element is preferably connected to at least one closing element, for example via an electromechanical coupling for separating and coupling the first actuating element with the closing element.
  • the closing element usually has at least one latch and / or one latch, which is retracted during a rotation of the shaft. Especially in panic locks and a bolt is withdrawn when a pusher operated on the inside of the door, so the shaft is rotated.
  • the actuating element is at least indirectly coupled to a generator.
  • Coupled means standing in operative connection, here so that an introduced via the actuator in the door lock mechanical power drives the generator, so that at least part of the mechanical power is converted by the generator into electrical power. Consequently, when a person actuates the actuator to open the door, a portion of the kinetic energy applied thereby may be converted to electrical energy to provide circuitry and, optionally, an actuator of an electromechanical clutch.
  • the circuit may e.g. check an authorization and if necessary close the coupling and thereby connect the corresponding actuating element and the closing element with each other or cancel a blocking of the closing element.
  • the door lock may have a first rotor, which is coupled for transmitting an actuation of a first actuating element to a generator with this.
  • the door lock may have a second rotor for transmitting an actuation of a second actuating element.
  • the first and / or the second rotor may or may be formed by a respective shaft on the side facing away from the door, a door handle is formed.
  • the door lock has a third rotor which drives a generator for supplying an electrical circuit.
  • the third rotor can be a runner of the generator in the simplest case.
  • the feed is preferably carried out with the interposition of at least one memory module for storing electrical energy, for example at least one capacitor and / or at least one accumulator.
  • the generator is via the third rotor with the first and the second Rotor coupled to each drive the generator during rotation of the first and / or the second rotor, wherein the first rotor does not entrain the second rotor and / or the second rotor does not entrain the first rotor.
  • the first and / or the second rotor can be connected, for example via at least one freewheel to the third rotor. Consequently, the two actuators can be actuated independently, each driving the generator.
  • the first (eg outer) actuating element via an electrically controlled coupling and the second (eg inner) actuating element permanently be connected to at least one closing element, whereby upon actuation of the second actuating element, the door can be opened without checking a key.
  • an emergency exit can be realized, which, however, can only be opened from the outside after checking a key, ie a circuit checks the key and controls the clutch accordingly. This corresponds to a so-called panic lock or anti-panic lock.
  • At least the first and / or the second actuating element is coupled with the interposition of at least one elastic coupling with the generator, the elastic coupling when exceeding a given torque to be transmitted or a given force to be transmitted part of the introduced via at least one of the actuators kinetic Converts energy into potential energy and preferably falls below the torque to be transmitted, or the force to be transmitted below a given value at least a portion of the potential energy as kinetic energy outputs to the generator.
  • This can be achieved for example by the interposition of a spiral and / or coil spring as an elastic coupling.
  • the torque is to be considered when the movement to be transmitted by the elastic coupling is a rotary movement and the force is to be considered when the movement to be transmitted by the spring element is a translatory, eg linear movement.
  • An intermediate elastic coupling can be used to flatten load peaks that occur during the transmission of mechanical power.
  • load peaks can arise, for example, in the case of very rapid and / or abrupt actuation of the actuating element.
  • When "flattening" the load peaks at least a portion of the kinetic energy introduced into the door lock by the user via the actuator is stored in the flexible coupling, i. It transforms kinetic energy into potential energy. Later, so preferably when the corresponding peak stress subsides, this stored potential energy is released as kinetic energy to the generator. This is done, unlike in the prior art, not only after reaching a minimum value of the stored potential energy, but as soon as the load is less than that due to the tension of the elastic coupling, e.g. a spring element resulting force. This allows a particularly secure and durable function of the door lock can be achieved. You could also (alternatively or additionally) provide a slip clutch to prevent the components are overstressed. This would give you a worse efficiency.
  • the limit beyond which the elastic coupling stores potential energy can be adjusted by the selection of a bias, e.g. by a spring preload.
  • a bias e.g. by a spring preload.
  • spring element is used as a synonym for a flexible coupling.
  • the limit below which this potential energy is delivered is preferably dependent on the respective spring tension and in the simplest and thus preferred case, the restoring force of the spring element or the restoring torque of the spring element in the given stored potential energy.
  • the electrical energy generated by the generator is preferably stored at least in part, for example in at least one capacitor and / or in one Accumulator. Their capacity should preferably be sufficient to store the energy required for at least one authorization check. Preferably enough energy is stored for multiple authorization checks.
  • authorization check preferably includes all sub-steps that are necessary for checking a key and possibly for closing and / or opening the clutch and / or for unlocking and / or locking the closing element.
  • the door lock has a second actuating element, which is coupled via the first spring element and / or a second spring element with the generator.
  • Each of the two actuating elements is preferably arranged on each of the two sides of the door, that is, the first actuating element on one (first) side of the door lock and the second actuating element on the other (second) side of the door lock.
  • the generator is activated. This sounds trivial at first, but it is not, because the two actuators unlike electromechanical door locks usually not rigidly coupled together, but are independently operable.
  • a freewheel is arranged between the first and / or second actuating element and the generator, which decouples at least the first actuating element from the generator when the first actuating element is moved back from an end position to an initial position.
  • This freewheel has two effects: First, the mechanical stress on the components of the door lock is reduced because the moving components of the generator and possibly provided gears or the like are not abruptly decelerated upon reaching the end stop of the actuator.
  • the generator as well as the freewheel downstream optional gears or other rotating components can run until they get their kinetic energy delivered to the generator. The corresponding kinetic energy is therefore also used to generate electrical energy.
  • the starting position is the position of the actuating element in which the actuating element is located before a user actuates it. It is usually reset by a return spring in this initial position when the actuator is released. As a rule, the position is defined by a stop. If the actuator is actuated, it usually has an end position, which is usually defined by a second stop. In the usual door handles corresponds to a horizontal door handle an actuator in the starting position. A door handle in the end position is about 30 ° (usually 25-35 °) pivoted against the horizontal down. The angle between the starting position and the end position is also referred to as the maximum operating angle.
  • the freewheel may have a self-locking roller clutch. This has the advantage that it is very reliable because it has no locking lugs.
  • very small slip angles can be realized with a roller clutch. As a slip angle of the angle is referred to the input and output of the freewheel maximum in the reverse direction against each other can be rotated.
  • the freewheel is arranged in a recess of a gear of a transmission, which couples the actuating element with the generator or with the spring element.
  • the output side of the freewheel is preferably the gear.
  • it acts like a flywheel, so as a kinetic energy storage.
  • it preferably has the largest possible circumference, so that, in conjunction with a smaller gear, which is at least indirectly coupled to the rotor of the generator, the number of revolutions of the rotor per degree of deflection of the actuating element (at a pivotable Actuator) increases, whereby the stored kinetic energy is further increased.
  • the voltage supplied by the generator can be increased.
  • the freewheel is arranged coaxially to a rotational axis of the actuating element, which allows a particularly space-saving arrangement.
  • the freewheel may include the third rotor, e.g. as a particular disc-shaped third rotor, which forms an inner body of the freewheel.
  • the inner body is coupled on a first side with the first actuating element.
  • the first rotor may be coupled to a second actuator having the function of the above-mentioned second rotor. Coupled here means that the first and second actuator each take the third rotor when they are operated.
  • Coaxially with the third rotor, on the third rotor e.g.
  • an outer body of a freewheel sitting as a fourth rotor which is freely rotatable against the third and thus also against the first and the second rotor in only one direction.
  • the third rotor and the outer body are rotatably coupled together. This can be done for example via a self-locking roller clutch, a pawl freewheel, a sprag freewheel or the like.
  • the coupling between the first and / or second actuating element or rotor and the third rotor via at least one coupling extension engages in a complementary recess to take the third rotor, ie in the direction of rotation, the boundary of the recess forms a stop.
  • the boundary of the recess is preferably set back so far that the third rotor can be rotated in the actuating direction at least by the maximum operating angle, without taking along the first and / or second actuating element.
  • this can be realized by a preferably annular segment-shaped recess be.
  • the first actuating element can engage in the recess from a first side and the second actuating element can engage in the recess from a second, opposite side.
  • each coupling extension can engage in a separate recess.
  • the third rotor on each of its two end faces could each have at least one coupling extension, each engaging in a ring-segment-shaped recess of the first and the second rotor.
  • a panic lock for example, the first rotor via an electromechanical coupling for separating and connecting to the second actuating element and / or the closing element at least indirectly rotatably connected.
  • a panic lock can then, for example, the second (eg door inside) actuator constantly in operative connection with the closing element, whereas the first (eg door outside) actuator is coupled only after a successful authorization examination, for example with the closing element by means of the electromechanical coupling with the closing element. Coupled means that two components are non-positively and / or torque-transmitting connected to each other, for example, rotatably connected to each other. In the uncoupled state, the force and / or torque transmitting connection is canceled.
  • Coupled components may e.g. a shaft and a gear with the interposition of a clutch.
  • first and / or second actuating element and the generator can preferably be a kinetic energy storage, for.
  • a flywheel be arranged. Thereby, the period in which the generator provides electrical power upon actuation of the actuator can be extended.
  • the first actuating element and the second actuating element may be coupled via a coupling element with the generator, wherein the coupling element has at least one recess into which a coupling extension of the first actuating element and a coupling extension of the second actuating element engage, whereby upon actuation of the first and / or second actuator, the coupling element is taken.
  • the third rotor described above may for example be such a coupling element. In basically the same way, a linear actuated coupling element can be realized.

  • the shaft 20 may also be referred to as the first control element 20, although strictly speaking, of course, the door handle itself is the operating element, however, the movement of the door handle on the shaft 20 is introduced into the module and this is what matters.
  • a second actuator such as an internal second door handle can be coupled to the assembly.
  • This square shaft usually passes through a driver of a conventional box lock, preferably a panic lock (not shown).

If a channel is released on the side facing away from the coupling element, the coupling element presses the blocking element into the channel and can thereby engage in the opening, as a result of which the two rotors are coupled to one another in a torque-proof manner.
  • the adapter 60 corresponds to one rotor and the outer body 40 corresponds to the other rotor.
  • the coupling is not limited to the application shown in the drawing.
