Definitions

  • the invention relates to a door handle and / or a knob for actuating a lock cylinder, each serving for actuating a box lock a door.
  • the door handle or the knob has an output shaft and a handle facing away from the door, which have a common axis of rotation and are connected to each other via an electromechanical clutch.
  • the output shaft has on the handle side facing a recess for a motor between an open position and a closed position axially displaceable coupling element and the handle has the recess opposite a receptacle for the coupling element.
  • 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 At least the case can usually be withdrawn via a door handle, usually in the form of a door handle to open the door. In so-called anti-panic locks and the bolt is coupled to the pusher, so that this is withdrawn upon actuation of the pusher.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 rotary movement of the door handle into the box lock, the box lock has a so-called nut, into which a square shaft extending orthogonally to the door leaf is usually inserted, so that it projects beyond the door leaf on at least one side.
  • 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 on a shaft, usually a square shaft on the so-called pusher nut, in short 'nut', a mortise lock (see, eg, DIN 18 251).
  • a door handle generally has two legs: a first leg whose longitudinal axis usually coincides, ie preferably coincides with the axis of rotation of the nut, and an angled second leg which acts as a lever. To actuate the door handle, the second leg is pivoted about the longitudinal axis of the first leg and rotates it accordingly. Usually, the first leg is significantly shorter than the second leg.
  • 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. If the user is granted authorization, the lock cylinders allow the lock cam to rotate, either with 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 lock bit In order to release the lock, the lock bit must be coupled in a rotationally fixed manner to a handle, for example with the knob, in the case of electromagnetic lock cylinders, ie be coupled.
  • a handle for example with the knob
  • the lock bit In the non-released state, at least the handle arranged on the outside of the door is not non-rotatably connected to the lock bit (decoupled).

  • the energy is usually supplied by batteries, so the energy needs of the clutch for a closing and opening process must be as low as possible.
  • 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, ie 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 electromechanical, so that a lock control can switch the clutch between the two states.
  • 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 slidably mounted in two slots of a connecting element, 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.

  • the invention has the object to improve the known from DE 10 2014 103 666 door handle to the effect that it is cheaper manufacturable and also works even more reliable. This object is achieved by the actuator door handle according to claim 1 and the drive carrier described below. Advantageous embodiments of the invention are specified in the subclaims.
