  • the gear housing 2 further includes a latching device 15 housed in its interior, which in two opposite, the opening or closing position of the window or door fitting corresponding end positions of the drive rods 5, 6 engages with one of the drive rods 6 to the Drive rod 6 to lock in the open or closed position of the window or door fitting with the gear housing 2.
  • the gear housing 2 consists of two in plan view substantially mirror-symmetrical housing halves 20, of which only one is shown in the drawing.
  • the two housing halves 20 produced, for example, from A-die-cast aluminum, have at their opposite front ends in each case an outlet opening 22 or 23 for the drive rod 5 or 6 and are on their broad side surfaces each with opposite cylindrical bearing recesses for the drive gear 3 and for the coupling gear 10 provided.
  • the gear housing has a seat 24 for releasably inserting the latching device 15.
  • the two housing halves 20 are joined together after the insertion of the drive rods 5 and 6, the drive gear 3, the coupling gear 10 and the latching device 15 and firmly connected.
  • the drive gear 3 has two surrounding the through hole 19 and projecting at its opposite end faces cylindrical bearing pin 24 (only one visible), which engage in the one pair of opposite bearing recesses of the housing halves 20.
  • the drive gear 3 is provided with a radially projecting circular segment-like flange 25 which is slidably guided between two parallel inner walls of the housing halves 20.
  • the flange 25 is provided on its outer periphery over an angle of about 90 °, corresponding to about a quarter circle segment, with a total of five protruding teeth 7, the mesh with the drive gear 3 with drive gear recesses 8 a spline of the drive rod 6 and thereby the drive rod 6 in response to the direction of rotation of the drive gear 3 in the direction of arrow A or B. relocate.
  • the axis of rotation 4 of the drive gear 3 is nut perennial care of the drive rod 6 is arranged.
  • coupling gear 10 also has two projecting on its opposite end faces cylindrical bearing pin 26 (only one visible), which engage in the other pair of opposite bearing recesses of the housing halves 20.
  • the coupling gear 10 is provided on its entire circumference with teeth 27, the number of which is six in the illustrated embodiment. Of these teeth 27 mesh one to two on one side of the coupling gear 10 with coupling gear recesses 11 further splines of the drive gear 3 driven drive rod 6. On the opposite side of the coupling gear 10 also mesh one to two of the teeth 27 with coupling gear recesses 12 of a longitudinal toothing of the other drive rod 5.
  • the distance between the recesses 12 corresponds exactly to the distance of the recesses 11, wherein the straight with the coupling gear 10 in meshing recesses 11 and 12 are seen from the axis of rotation 18 of the coupling gear 10 on diametrically opposite sides ,
  • the drive rod 5 is displaced axially by an axial displacement of the drive rod 6 by the same amount as this, but in the opposite direction.
  • the coupling gear recesses 11, 12 are each arranged in the end region of the drive rods 6 and 5 so that they are exactly opposite, when the drive rods 5 and 6 are located in a mid-position between their two end positions middle position.

  • the drive gear 3 also rotates clockwise. Since the teeth 7 of the drive gear 3 mesh with the recesses 8 of the drive rod 6, this is axially displaced in the direction of the arrow A.
  • the coupling gear 10 is also rotated in a clockwise direction, since the coupling gear recesses 11 mesh with the teeth of the coupling gear 10.
