  • the rotational movement of the nut element can then be derived directly to an adjustment of the fitting element, that is about to a displacement of a drive rod, for example, by a peripheral portion of the nut member cooperates with themaschinestrange.
  • the transmission can thus couple the handle with the fitting arrangement, in particular with a drive rod of the fitting arrangement, in an effective manner, so that an adjustment of the handle in a specific adjustment direction to a corresponding chenden displacement of the drive rod leads and an adjustment of the handle in an opposite adjustment leads to an opposite displacement of the drive rod.
  • this drive-effective coupling of the handle with the drive rod by the transmission also have the consequence that, conversely, an outgoing from the drive rod adjustment is transmitted by the transmission to the handle.
  • Such originating from the drive rod adjustment movement can be done, for example, in a manipulation attempt, such as when trying to open the window, the door or the like in an unauthorized manner, such as from the outside.
  • Closing mechanisms may be provided, for example, can be operated only by means of a key and are suitable, the fitting arrangement, for. to lock in a locked position.
  • locking mechanisms are complex and increase the cost of the fitting arrangement.
  • the object is achieved by a transmission with the features of claim 1 and by a transmission with the features of claim 3.
  • the transmission according to the invention comprises a housing and a nut element which is movably mounted in a nut receptacle of the housing and which is drive-effectively coupled to a fitting element, in particular a drive rod, of the fitting arrangement, wherein the nut element is pivotable between a release position in which it is rotatable about a housing-fixed axis of rotation , and a blocking position, in it is locked in at least one direction of rotation against rotation about the axis of rotation, is displaceable radially to the axis of rotation, and wherein the nut member is adapted to be placed in the locking position when it is in the release position and from the fitting element to a Movement is driven in the aforementioned direction of rotation.
  • the transmission is adapted to transmit an outgoing from the nut element adjustment movement through the transmission to the fitting element, in the reverse direction but not allow (as in a manipulation attempt) from the fitting element outgoing adjustment movement.
  • This is achieved in that, when the nut element is moved from the fitting element to a movement into an e.g. If the window or the door-opening direction of rotation is driven, this drive movement of the fitting element initially (or at least also) leads to the nut element being set in the blocking position. In the blocking position, the nut element can then not be driven further in the aforementioned direction of rotation, since it is locked against rotation in this direction.
  • the transmission is thus designed to be self-locking against an outgoing movement of the fitting element.
  • the release position and the locking position differ in particular with respect to their distance from the axis of rotation.
  • the nut element is therefore arranged differently eccentric to the axis of rotation in the two positions, wherein it is preferably arranged concentrically in the release position to the axis of rotation.
  • the possible rotational paths of the nut element differ in the two positions.
  • the release position and the locking position of the nut member are to be understood solely based on its radial orientation to the axis of rotation.
  • the nut element in these positions is not generally fixed to a certain rotational position.
  • the nut element in the release position can take a variety of different rotational positions relative to the axis of rotation.
  • the fact that the nut element is rotatable about the rotation axis in the release position means that the nut element can be rotated about the axis of rotation at least within a certain "free" rotation angle range, whereby the free rotation angle range is not necessarily full 360 °. In particular, it may be at least about 180 ° so that the nut element is e.g. in an adjustment of a coupled to the nut member handle from a vertically downward position in a vertically upward position passes through the entire possible rotation angle range.
  • the rotation angle range within which the nut element can be rotated in its blocking position about the axis of rotation, limited.
  • the fact that the nut member is locked in the locked position against rotation about the axis of rotation, does not necessarily mean that in the locked position no rotation about the axis of rotation is possible, even if this is preferred.
  • the restricted rotation angle range preferably comprises less than a third, in particular less than a quarter of the free rotation angle range.
  • the nut element is not necessarily displaceable in each rotational position between the release pitch and the blocking position.
  • the nut member is radially displaceable in the locked position, in particular to protect just this rotational position against a manipulation emanating from the fitting element.

  • the abutment surface can thus form just said blocking means, which is arranged within an eccentric rotational movement path of the nut element that corresponds to the blocking position and thereby restricts or even completely blocks its rotational mobility in at least one direction of rotation.
  • the abutment surface does not oppose a rotation of the nut element, since the rotational movement path corresponding to the release graduation runs past the abutment surface and is therefore not blocked by the abutment surface.

  • a regular operation is in particular present when the nut element is driven exclusively for rotation about the axis of rotation, ie substantially only a torque is experienced around the housing-fixed axis of rotation.

  • the nut element is not driven exclusively centrally about the axis of rotation, but rather tangentially to it.

  • the abutment surface can be aligned obliquely with respect to a radial direction to the axis of rotation, and be further offset with a radially inner end region in the direction of rotation to be blocked than with a radially outer end region. From a radial orientation, the orientation of the abutment surface can be adjusted by e.g. 30 ° to 45 °.
  • the angle is preferably chosen so that the resulting forces that the nut element exerts on the stop surface, depending on whether the nut element substantially exclusively experiences a torque about the axis of rotation or is acted upon by the fitting element, due to the inclination of the Stop surface are deflected to a displacement of the nut member in the release position or be absorbed by the stop surface blocking.

Position also a rotation through 90 ° in the opposite direction of rotation possible. In this case, in each case as a result of the rotation of the nut member 15, the fitting element in the longitudinal guide 53 is driven to a displacement.
